whether to be settled by the delivery of securities, cash or otherwise, (ii) any
option to enter into any of the foregoing, and (iii) any other similar
agreement, contract or transaction that, in the case of this clause (iii) only,
would (in the reasonable, good-faith judgment of one nationally-recognized
investment banking firm selected by each of the Issuer, on the one hand, and the
Stockholders holding a majority of the securities proposed to be included in
such Hedging Transaction, on the other hand) make it commercially impracticable
for more than one Hedging Counterparty to jointly effect such agreement,
contract or transaction or any related market hedge of the Hedging
Counterparty's economic exposure thereunder.

                  "Permitted Transferee" means any Person to whom a Stockholder

include any successor (by merger or otherwise) of such entity.

counsel to the effect that the securities evidenced thereby may be publicly sold

outside securities counsel to the Issuer, that either (1) such filing would
reasonably be expected to prevent the offer and sale of the Issuer Common Stock
to MediaOne under the

                                                                               9

Restructuring Agreement from being eligible for an exemption from registration
under the Securities Act or (2) the Commission's rules and regulations or the
Staff of the Commission would not permit a re-sale shelf Registration Statement
to be filed or declared effective prior to issuance of the Registrable
Securities. Subject to Section 3.5(b), if , pursuant to the preceding sentence,
the Issuer does not file the Shelf Registration Statement prior to the Closing,
the Issuer agrees that it shall file the Shelf Registration Statement promptly
(and in no event more than three Business Days) after the Closing and use all
commercially reasonable efforts to have the Shelf Registration Statement
declared effective as soon as practicable thereafter.

                           (c)      Subject to Section 3.1(b), the Issuer shall
use all commercially reasonable efforts to have the Shelf Registration Statement
declared effective on the Closing Date or promptly thereafter and shall use all
commercially reasonable efforts to keep the Shelf Registration Statement
continuously effective, subject to the provisions of Section 3.5, during the
time (the "Effectiveness Period") commencing on the date such Shelf Registration
Statement is declared effective (the "Effective Time") and ending on the earlier
to occur of (i) one year after the Closing and (ii) such time as all of the
Registrable Securities cease to be Registrable Securities; provided, however,
that (1) before filing a Registration Statement or Prospectus or any amendments
or supplements thereto, the Issuer shall provide counsel to MediaOne with a
reasonable opportunity to review and comment on such Registration Statement and
each Prospectus included therein (and each amendment and supplement thereto) to
be filed with the Commission, subject to such documents being under the Issuer's
control, and (2) the Issuer shall notify MediaOne and counsel to MediaOne of any
stop order issued or threatened by the Commission and take all commercially
reasonable actions required to prevent the entry of such stop order or to remove
it if entered. The one-year period in clause (i) of this Section 3.1(c) shall be
extended for a number of days equal to the number of days that elapse from (x)
the date any written notice contemplated by Section 3.5(a) is given by the
Issuer to (y) the date on which the Issuer delivers to the Stockholders the
supplement or amendment contemplated by Section 3.5(a).

                           (d)      At the Effective Time, each Stockholder (and
each Subsidiary of such Stockholder designated by such Stockholder) shall be
named as a selling securityholder in the Shelf Registration Statement and
related Prospectus in such a manner as to permit such Stockholder (and such
designee) to deliver such Prospectus to purchasers of Registrable Securities in
accordance with applicable law under ordinary circumstances. The "Plan of
Distribution" section of the Shelf Registration Statement and Prospectus shall
state that the Registrable Securities may be sold by the selling securityholders
following the Effective Time in any legal manner selected by the Stockholders.

                           (e)      If the Shelf Registration Statement ceases
to be effective for any reason at any time during the Effectiveness Period, the
Issuer shall, subject to the provisions of Section 3.5, use all commercially
reasonable efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event within 15 days after such cessation of
effectiveness amend the Shelf Registration Statement in a manner reasonably
expected by the Issuer to obtain the withdrawal of such order

                                                                              10


suspending the effectiveness thereof or, as promptly as practicable thereafter,
file an additional registration statement (the "Subsequent Registration
Statement") covering the resale by the Stockholders of all of the then
Registrable Securities on a delayed or continuous basis pursuant to Rule 415
under the Securities Act. If the Subsequent Registration Statement is filed, the
Issuer shall use all commercially reasonable efforts, subject to the provisions
of Section 3.5, to cause the Subsequent Registration Statement to become
effective under the Securities Act and remain continuously effective during the
Effectiveness Period.

                           (f)      The Issuer shall pay all Registration
Expenses incurred in connection with the Shelf Registration Statement, any
Subsequent Registration Statement and any supplements or amendments to them,
whether or not they become effective, and whether all, none or some of the
Registrable Securities are sold pursuant to any Registration Statement. It is
understood and agreed that the Issuer may also register for public offering and
sale pursuant to the Shelf Registration Statement or any Subsequent Registration
Statement, initially or by amendment, securities other than Registrable
Securities, but in doing so shall not limit any Stockholder's rights hereunder
(including any limitation arising by application of applicable rules under the
Securities Act with respect to securities of the Issuer sold pursuant to such
Shelf Registration Statement or Subsequent Registration Statement by any Person
other than a Stockholder) or adversely affect the Stockholder's ability to sell
its Registrable Securities.

                  3.2      Registration Procedures.

                           (a)      In connection with each Registration
Statement, subject to the provisions of Section 3.5, to effect the registration
of such Registrable Securities in accordance with the intended method of
distribution thereof, the Issuer shall, as promptly as practicable, use all
commercially reasonable efforts to:

                                    (i)      supplement or amend, if necessary,
the Registration Statement, as required by the registration form utilized by the
Issuer or by the instructions applicable to such registration form or by the
Securities Act or as reasonably required by the Requisite Holders, and the
Issuer shall furnish to the holders of the Registrable Securities to which the
Registration Statement relates copies of any such supplement or amendment prior
to its being used and/or filed with the Commission;

                                    (ii)     prepare and file with the
Commission such amendments and supplements to the Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep the
Registration Statement effective as required under Section 3.1 and to comply
with the provisions of the Securities Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement until the
expiration of the Effectiveness Period; notwithstanding anything to the contrary
in this Agreement, the Issuer shall not be required to file or have declared
effective more than one post-effective amendment to the Registration Statement
and shall not be required to file more than five supplements to the Prospectus
contained in such Registration Statement, in each case, in connection with one
or more Hedging Transactions or changes requested by the Stockholders to the
Plan of Distribution therein;

<PAGE>
                                                                              11


                                    (iii)    furnish to each seller of
Registrable Securities, prior to filing a Registration Statement, copies of such
Registration Statement in accordance with Section 3.1(c), and promptly
thereafter furnish such number of conformed 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 summary Prospectus) and any other
Prospectus filed under Rule 424 under the Securities Act, and such other
documents, as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities of such seller; in addition, the
Issuer shall promptly after receipt furnish to each Stockholder copies of the
portions of any and all transmittal letters and any other correspondence
(including, but not limited to, comment letters) with the Commission or any
other Governmental Entity relating to the sections of such Registration
Statement or amendment or supplement thereto entitled "Plan of Distribution" or
"Selling Stockholders"; and the Requisite Holders shall have the right to
request that the Issuer modify any such information contained in such
Registration Statement or amendment and supplement thereto pertaining to such
Stockholders in such sections, and the Issuer shall use all commercially
reasonable efforts to comply with such request; provided, however, that the
Issuer shall not have any obligation to modify any information if the Issuer
reasonably expects that so doing would cause the Registration Statement to
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
not misleading;

                                    (iv)     (1) register or qualify all
Registrable Securities and other securities covered by the Registration
Statement under such other securities or "blue sky" laws of such States of the
United States of America where an exemption is not available and as the sellers
of Registrable Securities covered by the Registration Statement shall reasonably
request, (2) keep such registration or qualification in effect during the
Effectiveness Period, (3) obtain the withdrawal of any order or other
determination suspending such registration or qualification during the
Effectiveness Period and (4) take all other commercially reasonable action which
may be reasonably necessary or advisable to enable such sellers to consummate
the disposition in such jurisdictions of the securities to be sold by such
sellers, except that the Issuer shall not for any such purpose be required to
(A) qualify generally to do business as a foreign corporation in any
jurisdiction wherein it would not but for the requirements of this clause (iv)
be obligated to be so qualified, (B) subject itself to taxation in any such
jurisdiction or (C) consent to general service of process in any such
jurisdiction;

                                    (v)      cause all Registrable Securities
covered by the Registration Statement to be registered with or approved by such
Governmental Entities as may be necessary in the written opinion of counsel to
the Issuer and counsel to the seller or sellers of Registrable Securities to
enable the seller or sellers thereof to consummate the disposition of such
Registrable Securities within the United States of America;

                                    (vi)     (1) cause all Registrable
Securities covered by such Registration Statement to be listed, effective as of
the Closing (or if not possible, as promptly thereafter as possible), subject to
official notice of issuance, on the New York

<PAGE>
                                                                              12


Stock Exchange, and (2) comply with all applicable rules of the New York Stock
Exchange so as to permit the continued listing of such securities on the New
York Stock Exchange;

                                    (vii)    during the time when a Prospectus
is required to be delivered under the Securities Act, promptly give notice to
all Stockholders selling securities pursuant to such Prospectus (1) of the
receipt by the Issuer 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 or threat in writing
of any proceeding for such purpose, (2) of the occurrence of any of the events
described in Section 3.5(a) (provided, however, that no notice by the Issuer
shall be required pursuant to this subclause (2) in the event that the Issuer
either promptly files a Prospectus supplement or amendment to update the
Prospectus or a Form 8-K or other appropriate Exchange Act report that is
incorporated by reference into the Registration Statement, which, in either
case, contains the requisite information with respect to such event that results
in the Registration Statement no longer containing any untrue statement of
material fact or omitting to state a material fact necessary to make the
statements contained therein not misleading) and (3) of the determination by the
Issuer that a post-effective amendment to a Registration Statement will be filed
with the Commission;

                                    (viii)   comply with all applicable rules
and regulations of the Commission, and, if requested, make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering the period of at least 12 months, but not more than 18 months,
beginning with the first full calendar month after the effective date of the
Registration Statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act and Rule 158 promulgated thereunder, and
promptly furnish to each such seller of Registrable Securities a copy of any
amendment or supplement to the Registration Statement or prospectus;

                                    (ix)     timely file the reports and
materials required to be filed by it under the Securities Act and the Exchange
Act and the rules and regulations adopted by the Commission thereunder
(including but not limited to the reports under Sections 13 and 15(d) of the
Exchange Act referred to in subparagraph (c) of Rule 144) and shall take all
commercially reasonable actions as a Stockholder or any broker or dealer
facilitating a sale of Registrable Securities may reasonably request to enable
such Stockholder to sell or hedge Registrable Securities without registration
under the Securities Act within the limitation of the exemptions provided by (a)
Rule 144 under the Securities Act, as such rule may be amended from time to
time, or (b) any similar rules or regulations hereafter adopted by the
Commission; upon the reasonable request of any Stockholder the Issuer shall
deliver to such Stockholder a written statement as to whether it has complied
with such request;

                                    (x)      cooperate with each holder to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities sold pursuant to a Registration Statement, and provide
the transfer agent for the Registrable Securities with certificates for the
Registrable Securities that are in a form eligible for deposit with The
Depository Trust Company; and

<PAGE>
                                                                              13


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

                           (b)      The Issuer may require each seller of
Registrable Securities to (1) furnish the Issuer such information regarding such
seller and the distribution of such securities as the Issuer may from time to
time reasonably request in writing, (2) agree to comply with the Securities Act
and the Exchange Act and all applicable state securities laws and to use all
commercially reasonable efforts to comply with all applicable regulations in
connection with the registration and distribution of the Registrable Securities,
and (3) use all commercially reasonable efforts to enter into and perform
customary agreements (including agreements relating to an Underwriting) and take
such other actions as are prudent and reasonably required in order to expedite
or facilitate the disposition of such Registrable Securities.

                           (c)      Each holder of Registrable Securities agrees
by acquisition of such Registrable Securities that, upon receipt of any notice
from the Issuer of the happening of any event of the kind described in clauses
(i), (ii) and (iii) of the first sentence of Section 3.5(b) and subject to the
last two sentences of Section 3.5(b), such holder shall forthwith discontinue
such holder's disposition of Registrable Securities pursuant to the Registration
Statement until such holder receives copies of the supplemented or amended
Prospectus contemplated by Section 3.5(a) or 3.2(a)(vii) and, if so directed by
the Issuer, will promptly deliver to the Issuer (at the Issuer's expense) all
copies, other than permanent file copies, then in such holder's possession of
the Prospectus relating to such Registrable Securities current at the time of
receipt of such notice.

                           (d)      If any shares of Issuer Common Stock are to
be sold in an underwritten public offering, which, for the avoidance of doubt,
the parties agree includes (1) a transaction in which the underwriter or
underwriters act as principal for the sale of Registrable Class Securities
pursuant to any Registration Statement (including in order to hedge its economic
exposure to a Hedging Transaction) and (2) a transaction that constitutes an "at
the market offering" (as such term is defined in Rule 415 under the Securities
Act), in which the counterparty acts as agent (and not as principal) (each, an
"Underwriting"):

                                    (i)      Subject to subclauses (ii) and
(iii) of this Section 3.2(d), the Issuer shall enter into an underwriting or
similar agreement of the type customary or reasonably appropriate for the types
of offerings which are most similar to such Underwriting, among the Issuer, the
selling Stockholder or Stockholders and the counterparties, which agreement
shall include, without limitation, customary provisions relating to: (1)
representations and warranties of the Issuer and the selling Stockholder or
Stockholders to the counterparties; (2) the performance by the counterparties
and their representatives of a reasonable "due diligence" investigation of the
Issuer; (3) receipt by the counterparties of accountant's "comfort" letters,
addressed to such counterparties, in customary form and covering such matters as
are customarily covered by "cold comfort" letters delivered in connection with
such type of transaction; (4) receipt by the counterparties of disclosure
opinions, addressed to such counterparties, of internal

<PAGE>
                                                                              14


counsel to the Issuer (or, at the Stockholders' expense, of nationally
recognized outside counsel to the Issuer), in customary form and covering such
matters as are customarily covered by such opinions delivered in connection with
such type of transaction, which opinion is reasonably acceptable to the
counterparty; (5) receipt by the counterparties of other reasonable and
customary certificates and closing documents; and (6) indemnification of, and
contribution in connection with the liability of, the counterparties and their
control persons arising from the Underwriting, which indemnity is reasonably
acceptable to the counterparty. Notwithstanding anything to the contrary in this
Agreement, the employees of the Issuer shall not be required to participate in
any "road shows" or similar marketing activities.

                                    (ii)     Subject to subclause (iii), in the
case of any Underwriting that is an "at the market offering" (as such term is
defined in Rule 415 under the Securities Act) in which the counterparty acts as
agent (and not as principal), the Issuer shall be required to enter into only
one such underwriting or similar agreement on or prior to the commencement date
of such offering (a "Dribble Out Agreement"). Such Dribble Out Agreement shall
remain effective until the end of the Effectiveness Period, and the comfort
letters, opinions, certificates and closing documents described in subclause (i)
shall be delivered only at the time of execution of such Dribble Out Agreement
(except as required under Section 3.2(d)(iv)).

                                    (iii)    Notwithstanding the foregoing, the
Issuer shall not be obligated to enter into any underwriting or similar
agreement, furnish the documents and information set forth in Section 3.2(d)(i),
permit the counterparties to conduct due diligence investigations or provide
indemnification or contribution, in each case, as contemplated by Section
3.2(d)(i) or (ii), on more than three occasions. The Issuer shall use all
commercially reasonable efforts to provide such comfort letters, opinion,
certificates and closing documents contemplated by this Section 3.2(d) within 10
Business Days after a request therefor by the Stockholders.

                                    (iv)     In addition, on one occasion only,
in connection with an Underwriting pursuant to a Dribble Out Agreement as to
which sales of securities thereunder were prohibited pursuant to Section 3.5
prior to the 20th trading day on the New York Stock Exchange after the
effectiveness of such Dribble Out Agreement, the Issuer shall use all
commercially reasonable efforts to obtain the comfort letters, opinions,
certificates and other documents described in Section 3.2(d)(i), at the end of
such Deferral Period.

                  3.3      Indemnification.

                           (a)      The Issuer agrees to indemnify and hold
harmless each Stockholder, its partners, directors, officers, other Affiliates
and each Person who controls (within the meaning of Section 15 of the Securities
Act) such Stockholder from and against any and all losses, claims, damages,
liabilities and expenses, or any action or proceeding in respect thereof
(including reasonable costs of investigation and reasonable attorneys' fees and
expenses) (each, a "Liability" and collectively, "Liabilities"), arising out of
or based upon any untrue, or allegedly untrue, statement of a material fact
<PAGE>
                                                                              15


contained in any Registration Statement, Prospectus or preliminary Prospectus or
notification or offering circular (as amended or supplemented if the Issuer
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; provided, however,
that the Issuer shall not be liable (i) in any such case to the extent that any
such Liability arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in such Registration
Statement, Prospectus or preliminary Prospectus or notification or offering
circular in reliance upon and in conformity with written information furnished
to the Issuer by or on behalf of such Stockholder (including, without
limitation, the information provided pursuant to Section 3.2(b) or 3.3(b)),
specifically for use in the preparation thereof and (ii) for any Liability if
(1) the Issuer has notified such Stockholder to suspend use of the Prospectus
pursuant to Section 3.5(a) or (b), (2) such Stockholder continues to use the
relevant Prospectus notwithstanding such notice, and (3) such Liability arises
from or is based upon an untrue statement or alleged untrue statement of any
material fact or omission to state a material fact that was cured in the
supplemented or amended Prospectus contemplated by Section 3.5(a) or (b).

                           (b)      Indemnification by each Stockholder. Each
Stockholder shall promptly furnish to the Issuer in writing such information
with respect to such Stockholder and the distribution of the Registrable
Securities as the Issuer may reasonably request or as may be required by law for
use in connection with any Registration Statement or Prospectus and all
information required to be disclosed in order to make the information previously
furnished to the Issuer by such Stockholder not materially misleading or
necessary to cause such Registration Statement not to omit a material fact with
respect to such Stockholder necessary in order to make the statements therein
not misleading. Each Stockholder agrees, severally but not jointly, to indemnify
and hold harmless the Issuer, any underwriter retained by the Issuer, their
respective directors, officers and other Affiliates and each Person who controls
the Issuer or such underwriter (within the meaning of Section 15 of the
Securities Act) to the same extent as the indemnity from the Issuer to such
Stockholder under Section 3.3(a) but only with respect to information provided
by such Stockholder or on such Stockholder's behalf expressly for use in the
Registration Statement or Prospectus relating to the Registrable Securities;
provided, however, that the liability of each Stockholder under this Section
3.3(b) shall be limited to the amount of net proceeds received by such
Stockholder in the transaction giving rise to such Liability.

                           (c)      Notices of Claims, etc. Any Person entitled
to indemnification under this Section 3.3 (each, an "Indemnified Party") agrees
to give prompt written notice to each indemnifying party (each, an "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 forfeits substantive

<PAGE>
                                                                              16


rights or defenses by reason of such failure), and in no event shall such
failure relieve the Indemnifying Party from any other Liability it may have to
such Indemnified Party. 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. 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 the defense of such
action, (iii) the Indemnifying Party and the Indemnified Party shall have
mutually agreed to the retention of such counsel or (iv) 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 presents a conflict of interest or (y)
there may be one or more legal defenses available to the Indemnified Party which
are different from, inconsistent with or additional to those available to the
Indemnifying Party. In any of the cases specified in clauses (ii) and (iv) of
the immediately preceding sentence, 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)      If the indemnification provided for in this
Section 3.3 shall for any reason be held by a court of competent jurisdiction to
be unavailable to an Indemnified Party, in respect of any Liability, then, in
lieu of the amount paid or payable under Section 3.3(a) or (b), as the case may
be, the Indemnified Party and the Indemnifying Party shall contribute to the
aggregate Liabilities in such proportion as is appropriate to reflect the
relative fault of the Issuer and the prospective sellers of Registrable
Securities covered by the Registration Statement in connection with the
statements or omissions which resulted in such loss, claim, damage or liability,
or action or proceeding in respect thereof, as well as any other relevant
equitable considerations (the relative fault of the Issuer and such prospective
sellers to 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 Issuer
or such prospective sellers and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or
omission). The parties hereto acknowledge that in no event shall the obligation
of any Indemnifying Party to contribute under this Section 3.3(d) exceed the
amount that such Indemnifying Party would have been obligated to pay by way of
indemnification if the indemnification provided for under Section 3.3(a) or (b)
had been available under the circumstances. The

Issuer and each Stockholder agree that it would not be just and equitable if
contribution pursuant to this Section 3.3(d) were determined by pro rata
allocation (even if such Stockholders were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the first sentence of this Section
3.3(d). 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. Such prospective
sellers' obligations to contribute as provided in this Section 3.3(d) are
several in proportion to the relative value of their respective Registrable
Securities covered by such Registration Statement and not joint.

                           (e)      Indemnification Payments. The
indemnification and contribution required by this Section 3.3 shall be made by
prompt periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.

                  3.4      Transfer of Registration Rights.

                           (a)      Each Stockholder may transfer Registrable
Securities with the associated registration rights under this Agreement to a
Permitted Transferee or pledgee ("Pledgee") only if (1) such Permitted
Transferee or Pledgee agrees in writing to be bound as a Stockholder by the
provisions of this Agreement insofar as it pertains to the holding, owning and
disposition of Registrable Securities and (2) immediately following such
transfer or pledge, the further disposition of such Registrable Securities by
such Permitted Transferee or Pledgee would be restricted under the Securities
Act.

                           (b)      Upon any transfer of Registrable Securities
other than as set forth in this Section 3.4, such securities shall no longer
constitute Registrable Securities, except that any Registrable Securities that
are pledged or made the subject of a Hedging Transaction, which Registrable
Securities are not ultimately disposed of by the Stockholders pursuant to such
pledge or Hedging Transaction shall, to the extent such securities remain
"restricted securities" under the Securities Act, be deemed to remain
"Registrable Securities" notwithstanding the release of such pledge or the
completion of such Hedging Transaction.

                           (c)      If a Stockholder assigns its rights under
this Agreement in connection with the transfer of less than all of its
Registrable Securities, such Stockholder shall retain its rights under this
Agreement with respect to its remaining Registrable Securities. If a Stockholder
assigns its rights under this Agreement in connection with the transfer of all
of its Registrable Securities, such Stockholder shall have no further
obligations under this Agreement, except under Section 3.3, with respect to
transactions occurring prior to such assignment.

                  3.5      Suspension of Sales.

                           (a)      The Issuer shall promptly notify each
Stockholder selling securities pursuant to a Prospectus (1) upon discovery that,
or upon the happening of any

<PAGE>
                                                                              18


event as a result of which, the Prospectus or the Registration Statement
includes 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, or the
occurrence of any event specified in clause (b) below; (2) of the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement or (3) of any written request by the Commission for
amendments to the Registration Statement or supplements or amendments to the
Prospectus. In no event shall the Issuer be required, in such notice to the
Stockholders, to set forth the details of any such event, order or request.
Immediately following any such event (x) upon the request of the Issuer, each
Stockholder shall suspend the use of the Prospectus and shall not sell any
Registrable Securities until such Stockholder has received copies of the
supplemented or amended Prospectus or until it is advised by the Issuer that the
Prospectus may be used, and (y) the Issuer shall use all commercially reasonable
efforts to, as promptly as practicable or in the case of an event specified in
clause (b) below, by the end of the Deferral Period (as defined below), prepare
and file a post-effective amendment to the Registration Statement or a
supplement or amendment to the related Prospectus or any document that would be
incorporated by reference into the Registration Statement and Prospectus so that
the Registration Statement does 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 such Prospectus
does 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 light of the circumstances under which they were made, not
misleading and promptly thereafter deliver to the holders of the Registrable
Securities a reasonable number of copies of the supplement or amendment of such
Prospectus complying with the foregoing, and, in the case of a post-effective
amendment to a Registration Statement, use all commercially reasonable efforts
to cause it to be declared effective as promptly as is reasonably practicable.

                           (b)      The Issuer shall not be required to file any
Registration Statement pursuant to this Agreement, file any amendment thereto,
furnish any supplement or amendment to a Prospectus included in a Registration
Statement pursuant to Section 3.2(a)(i) or 3.2(a)(ii), make any other filing
with the Commission, cause any Registration Statement or other filing with the
Commission to become effective, or take any similar action (collectively,
"Registration Actions") and may withdraw any Registration Statement or other
filing with the Commission, and any and all sales of Registrable Securities by a
holder thereof pursuant to a Registration Statement shall be suspended: (i) if
such Registration Action would, in the good-faith judgment of the Board of
Directors, materially interfere with business activities or plans of the Issuer,
or (ii) if such Registration Action would, in the good-faith judgment of the
Board of Directors, require the disclosure of material non-public information
which disclosure, in the good-faith judgment of the Board of Directors, would be
detrimental to the Issuer or (iii) if such Registration Action would require the
inclusion of audited financial statements of the Issuer that are not then
available. Upon the occurrence of any condition described in clauses (i), (ii)
or (iii) of the first sentence of this Section 3.5(b), the Issuer shall give
prompt notice thereof (which notice shall state whether it intends to delay any
of the Registration Actions and/or suspend sales of Registrable Securities) to
the

<PAGE>
                                                                              19


Stockholders. Upon the termination of the condition described in clauses (i),
(ii) or (iii) of the first sentence of this Section 3.5(b), the Issuer shall
give prompt notice to the holders of Registrable Securities and shall promptly
proceed with the Registration Actions and make any other filing with the
Commission required of it or terminate any suspension of sales it has put into
effect and shall take all such other commercially reasonable actions to permit
registered sales of Registrable Securities as contemplated by this Agreement. It
is understood and agreed that the foregoing provisions of this Section 3.5(b)
shall not prevent a sale or hedge pursuant to Rule 144 by a holder of
Registrable Securities or pursuant to any other exemption from the registration
requirements under the Securities Act. Notwithstanding anything to the contrary
in this Section 3.5(b), the Issuer may only delay Registration Actions or
suspend sales of Registrable Securities for three periods (each, a "Deferral
Period") of up to 120 days, in the aggregate, in any period of twelve
consecutive months. In addition, no suspension pursuant to Section 3.5(b) shall
be effective unless (x) each director and executive officer of the Issuer is
also prohibited by the Issuer's insider trading policy or otherwise from making
purchases and sales (other than those made pursuant to plans designed to comply
with Rule 10b5-1(c)(1)(i) under the Exchange Act) by reason of the condition
specified in the first sentence of Section 3.5(b) and (y) each other holder
entitled to sell equity securities of the Issuer pursuant to registration rights
under a selling stockholder prospectus is, or agrees to be, subject to deferral
provisions substantially similar to or more restrictive than those contained in
Section 3.5(b).

                  3.6      Registration in Connection with Hedging Transactions.

                           (a)      The Issuer acknowledges that from time to
time a Stockholder may seek to enter into one or more Hedging Transactions with
a Hedging Counterparty. Notwithstanding anything to the contrary provided
herein, the Issuer agrees that, in connection with any proposed Hedging
Transaction, if, in the reasonable judgment of Stockholder Counsel (after
good-faith consultation with counsel to the Issuer), it is necessary or
desirable to register under the Securities Act such Hedging Transaction or sales
or transfers (whether short or long) of Registrable Class Securities in
connection therewith, then the Issuer shall use all commercially reasonable
efforts to take such actions (which may include, among other things, the filing
of a post-effective amendment to the Registration Statement to include
additional or changed information that is material or is otherwise required to
be disclosed, including, without limitation, a description of such Hedging
Transaction, the name of the Hedging Counterparty, identification of the Hedging
Counterparty or its Affiliates as underwriters or potential underwriters, if
applicable, or any change to the Plan of Distribution) as may reasonably be
required to register such Hedging Transactions or sales or transfers of
Registrable Class Securities in connection therewith under the Securities Act in
a manner consistent with the rights and obligations of the Issuer hereunder with
respect to the registration of Registrable Securities.

                           (b)      The Issuer further agrees to include under
the caption "Plan of Distribution" (or the equivalent caption) in each
Registration Statement, and any related prospectus (to the extent such inclusion
is permitted under applicable Commission regulations and is consistent with
comments received from the Commission during any

<PAGE>
                                                                              20


Commission review of the Registration Statement), language in substantially the
form of Annex A hereto and to include in each prospectus supplement filed in
connection with any proposed Hedging Transaction language mutually agreed upon
by the Issuer, the relevant Stockholder and the Hedging Counterparty describing
such Hedging Transaction.

                           (c)      Any information regarding the Hedging
Transaction included in a Registration Statement or Prospectus pursuant to this
Section 3.6 shall be deemed to be information provided by the Stockholders
selling Registrable Securities pursuant to such Registration Statement for
purposes of Section 3.3.

                           (d)      If in connection with a Hedging Transaction
a Hedging Counterparty or any Affiliate thereof is (or may be considered) an
underwriter or selling stockholder, then it shall be required to provide
customary indemnities to the Issuer regarding itself, the Plan of Distribution
and like matters.

                           (e)      In addition, regardless of whether the
Hedging Counterparty in any Hedging Transaction is considered under applicable
law to be an underwriter, in any Hedging Transaction other than an OTC Hedging
Transaction, where the aggregate Market Value of Registrable Securities proposed
to be hedged is greater than $375 million, (i) the Stockholders holding a
majority of the securities proposed to be included in such Hedging Transaction
shall have the right to select one nationally-recognized investment banking firm
to act as a co-lead book-running Hedging Counterparty (or the equivalent) with
respect to such Hedging Transaction, which firm shall be reasonably acceptable
to the Issuer; and (ii) the Issuer shall have the right to select one
nationally-recognized investment banking firm to act as a co-lead book-running
Hedging Counterparty (or the equivalent) with respect to such Hedging
Transaction, which firm shall be reasonably acceptable to the Stockholders
holding a majority of the securities proposed to be included in such Hedging
Transaction. To the extent that the Issuer has the right to select a
nationally-recognized investment banking firm to act as a co-lead book-running
Hedging Counterparty (or the equivalent) pursuant to this Section 3.6(e), the
Stockholders proposing to effect such Hedging Transaction shall give the Issuer
reasonable notice, taking into account the type of Hedging Transaction, of their
intention to enter into such Hedging Transaction, which notice shall contain a
reasonably detailed description of the terms of such Hedging Transaction.

                  3.7      Underwriting. In any underwritten public offering of
Registrable Securities (other than an OTC Hedging Transaction) pursuant to a
Registration Statement filed under this Agreement in which at least $500 million
of Registrable Securities or all remaining Registrable Securities are proposed
to be sold, (i) Stockholders holding a majority of the Registrable Securities to
be sold pursuant to such offering shall have the right to select one
nationally-recognized investment banking firm to act as a co-lead book running
manager (or the equivalent) with respect to such offering, which firm shall be
reasonably acceptable to the Issuer; and (ii) the Issuer shall have the right to
select only one nationally-recognized investment banking firm as a co-lead book
running manager (or the equivalent) with respect to such offering, which firm
shall be reasonably

                                                                              21


acceptable to Stockholders holding a majority of the Registrable Securities to
be sold pursuant to such offering.

exchange for or in substitution of, such shares of Issuer 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 Issuer shall cause any successor or assign or acquiror (whether by merger,

Stockholder than the terms provided under this Agreement as a condition of any
such transaction.

place of receipt. Any party to this Agreement may change the address to which

                  4.3      Entire Agreement; No Inconsistent Agreement.

                           (a)      This Agreement constitutes the entire
agreement among the parties hereto and supersedes any prior understandings,
agreements or representations by or among the parties hereto, or any of them,
written or oral, with respect to the subject matter hereof.

                           (b)      The Issuer shall not hereafter enter into or
amend any agreement with respect to its securities which would adversely affect
the rights granted to the holders of Registrable Securities in this Agreement.

                  4.4      Further Assurances. Each of the parties shall execute
such documents and perform such further acts as may be reasonably required or
desirable to carry out or perform the provisions of this Agreement.

                  4.5      Other Agreements. Nothing contained in this Agreement
shall be deemed to be a waiver of, or release from, any obligations any party
hereto may have under any of the other Transaction Agreements.

                  4.6      No Third-Party Beneficiaries. Except as provided in
Section 3.3, this Agreement is not intended, and shall not be deemed, to confer
any rights or remedies upon any Person other than the parties hereto and their
respective successors and permitted assigns or to otherwise create any
third-party beneficiary hereto.

                  4.7      Assignment. This Agreement shall be binding upon and
inure to the benefit of and shall be enforceable by the parties hereto and their
respective successors and assigns and, with respect to each Stockholder, any
Permitted Transferee. No assignment or transfer shall be effective hereunder
unless and until the purported transferee executes and delivers an agreement, in
form and substance reasonably acceptable to the parties, agreeing to be bound by
the terms hereof.

                  4.8      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 the Issuer and the Requisite
Holders.

                  4.9      Nominees for Beneficial Owners. In the event that any
Registrable Securities are held by a nominee for the beneficial owner thereof,
the beneficial owner thereof may, at its election in writing delivered to the
Issuer, be treated as the holder of such Registrable Securities for purposes of
any request, consent, waiver or other action by any holder or holders of
Registrable Securities pursuant to this Agreement or any

                                                                              24


determination of any number or percentage of shares of Registrable Securities
held by any holder or holders of Registrable Securities contemplated by this
Agreement. If the beneficial owner of any Registrable Securities so elects, the
Issuer may require assurances reasonably satisfactory to it of such owner's
beneficial ownership of such Registrable Securities.

                  4.10     Severability. Any term or provision of this Agreement
that is invalid or unenforceable in any situation in any jurisdiction shall not
affect the validity or enforceability of the remaining terms and provisions
hereof or the validity or enforceability of the offending term or provision in
any other situation or in any other jurisdiction. If the final judgment of a
court of competent jurisdiction declares that any term or provision hereof is
invalid or unenforceable, the parties hereto agree that the court making such
determination shall have the power to limit the term or provision, to delete
specific words or phrases, or to replace any invalid or unenforceable term or
provision with a term or provision that is valid and enforceable and that comes
closest to expressing the intention of the invalid or unenforceable term or
provision, and this Agreement shall be enforceable as so modified. In the event
such court does not exercise the power granted to it in the prior sentence, the
parties hereto agree to replace such invalid or unenforceable term or provision
with a valid and enforceable term or provision that shall achieve, to the extent
possible, the economic, business and other purposes of such invalid or
unenforceable term.

                  4.11     Counterparts and Signature. This Agreement may be
executed in two or more counterparts, each of which shall be deemed an original
but all of which together shall be considered one and the same agreement and
shall become effective when counterparts have been signed by each of the parties
hereto and delivered to the other parties, it being understood that all parties
need not sign the same counterpart. This Agreement may be executed and delivered
by facsimile transmission.

                  4.12     Interpretation. When reference is made in this
Agreement to an Article or Section, such reference shall be to an Article or
Section of this Agreement, unless otherwise indicated. The headings contained in
this Agreement are for convenience of reference only and shall not affect in any
way the meaning or interpretation of this Agreement. The language used in this
Agreement shall be deemed to be the language chosen by the parties hereto to
express their mutual intent, and no rule of strict construction shall be applied
against any party. Whenever the context may require, any pronouns used in this
Agreement shall include the corresponding masculine, feminine or neuter forms,
and the singular form of nouns and pronouns shall include the plural, and vice
versa. Any reference to any federal, state, local or foreign statute or law
shall be deemed also to refer to all rules and regulations promulgated
thereunder, unless the context requires otherwise. Whenever the words "include",
"includes" or "including" are used in this Agreement, they shall be deemed to be
followed by the words "without limitation."

                  4.13     Governing Law. This Agreement shall be governed by
and construed in accordance with the internal laws of the State of New York
without giving effect to any choice or conflict of laws provision or rule
(whether of the State of

                                                                              25


New York or any other jurisdiction) that would cause the application of laws of
any jurisdictions other than those of the State of New York.

                  4.14     Submission to Jurisdiction. Any suit, action or
proceeding seeking to enforce any provision of, or based on any matter arising
out of or in connection with, this Agreement or the transactions contemplated
hereby shall be brought exclusively in any federal or state court located in the
State and City of New York, and each of the parties hereby consents to the
jurisdiction of such courts (and of the appropriate appellate courts therefrom)
in any such suit, action or proceeding and irrevocably waives, to the fullest
extent permitted by law, any objection that it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding in any such court or
that any such suit, action or proceeding brought in any such court has been
brought in an inconvenient forum. Process in any such suit, action or proceeding
may be served on any party anywhere in the world, whether within or without the
jurisdiction of any such court. Without limiting the foregoing, each party
agrees that service of process on such party as provided in Section 4.2 as to
giving notice hereunder shall be deemed effective service of process on such
party.

                  4.15     Remedies. Except as otherwise provided herein, any
and all remedies herein expressly conferred upon a party shall be deemed
cumulative with and not exclusive of any other remedy conferred hereby, or by
law or equity upon such party, and the exercise by a party of any one remedy
shall not preclude the exercise of any other remedy. The parties hereto agree
that irreparable damage would occur in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or
were otherwise breached. It is accordingly agreed that the parties shall be
entitled to an injunction or injunctions to prevent breaches of this Agreement
and to enforce specifically the terms and provisions of this Agreement, this
being in addition to any other remedy to which the parties are entitled at law
or in equity.

                  4.16     WAIVER OF JURY TRIAL. EACH OF THE ISSUER AND THE
STOCKHOLDERS HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR
OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THE ACTIONS OF THE ISSUER AND THE STOCKHOLDERS IN THE
NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

                              PLAN OF DISTRIBUTION

                  A selling stockholder may also enter into hedging and/or
monetization transactions. For example, a selling stockholder may:

(a)      enter into transactions with a broker-dealer or affiliate of a
broker-dealer or other third party in connection with which that other party
will become a selling stockholder and engage in short sales of the common stock
under this prospectus, in which case the other party may use shares of common
stock received from the selling stockholder to close out any short positions;

(b)      itself sell short common stock under this prospectus and use shares of
common stock held by it to close out any short position;

(c)      enter into options, forwards or other transactions that require the
selling stockholder to deliver, in a transaction exempt from registration under
the Securities Act, common stock to a broker-dealer or an affiliate of a
broker-dealer or other third party who may then become a selling stockholder and
publicly resell or otherwise transfer that common stock under this prospectus;
or

(d)      loan or pledge common stock to a broker-dealer or affiliate of a
broker-dealer or other third party who may then become a selling stockholder and
sell the loaned shares or, in an event of default in the case of a pledge,
become a selling stockholder and sell the pledged shares, under this prospectus.
