any Holder shall have the right to request that the Company effect a
registration under the Securities Act of all or any part of such Holder's
Registrable Securities. Any such request for registration by any Holder
pursuant to this Section 2.1 shall hereinafter be referred to as a "Demand
Registration Request" and the registrations so requested are referred to
herein as "Demand Registrations" (with respect to any Demand Registration,
the Holder(s) making such demands for registration


<PAGE>

                                                                        Page 3

being referred to as the "Initiating Holder"). Each Demand Registration
Request shall be delivered in writing to the Company and shall specify the
aggregate amount of Registrable Securities to be included in such
registration by the Company and the intended method of distribution
thereof.

                   (ii) After receiving a Demand Registration Request, the
Company shall, as promptly as practicable but in any event within
seventy-five (75) days, file a registration statement relating to such
Registrable Securities for distribution in accordance with such intended
method of distribution, and use its reasonable best efforts to cause such
registration statement to be declared effective under the Securities Act as
promptly as practicable.

               (b) The Company, subject to Sections 2.2 and 2.4, may elect
to include in any registration statement and offering made pursuant to this
Section 2.1 any other shares of Common Stock which are requested to be
included in such registration pursuant to the exercise of piggyback
registration rights granted by the Company.

               (c) A Holder may withdraw its request to include Registrable
Securities in a Demand Registration at any time prior to the related
registration statement's being declared effective by giving written notice
to the Company of its intent to withdraw.

               (d) A registration of Registrable Securities shall not
constitute a Demand Registration until a registration statement with
respect to such Registrable Securities shall have become effective.

          2.2. Limitation on Obligations to Effect Demand Registration.

               (a) The Demand Registration rights granted to Holders in
Section 2.1 are subject to the following limitations:

                   (i) the Company shall not be required to effect more
than three (3) Demand Registrations;

                   (ii) the Company shall not be required to effect more
than one (1) Demand Registration in any 180 day period;

                   (iii) the Company shall not be required to effect a
Demand Registration if the number of Registrable Securities requested to be
included is less than 1,500,000; provided, however, that in the event a
Demand Registration Request includes less than 1,500,000 Registrable
Securities, the Company shall be obligated to effect a registration if all
of the Holder's remaining Registrable Securities are included in such
Demand Registration Request;

                   (iv) the Company shall not be required to cause a
registration pursuant to Section 2.1(a) to be declared effective within a
period of one hundred thirty-five (135) days after the effective date of
any registration statement of the Company other than a registration
statement on Form S-8 (or an equivalent registration form then in effect);
and

<PAGE>


                                                                        Page 4

                    (v) if the Board of Directors of the Company, in its
reasonable business judgment, determines that any registration of
Registrable Securities should not be made or continued (the "Board
Decision") because it would interfere with any material financing,
acquisition, corporate reorganization or merger or result in premature
disclosure thereof (a "Valid Business Reason"), (A) the Company may
postpone filing a registration statement relating to a Demand Registration
until such Valid Business Reason no longer exists, but in no event for more
than ninety (90) days from the date of the Board Decision, and (B) in case
a registration statement has been filed relating to a Demand Registration,
the Company may cause such registration statement to be withdrawn and its
effectiveness terminated or may postpone amending or supplementing such
registration statement until such Valid Business Reason no longer exists,
but in no event for more than ninety (90) days from the date of the Board
Decision (such period of postponement or withdrawal under subclauses (A) or
(B) of this clause (vi), the "Postponement Period"); and the Company shall
give written notice to the Initiating Holder of its determination to
postpone or withdraw a registration statement, and of the fact that the
Valid Business Reason for such postponement or withdrawal no longer exists,
in each case, promptly after the occurrence thereof; provided, however, the
Company shall not be permitted to postpone or withdraw a registration
statement after the expiration of any Postponement Period until twelve
months after the expiration of such Postponement Period without the prior
written approval of the Initiating Holder of such Demand Registration and
the Company shall not be permitted to postpone or withdraw a registration
statement during the period commencing on the date hereof and ending on the
270th day following the date hereof.

               (b) If the Company shall give any notice of postponement or
withdrawal of any registration statement, the Company shall not, during the
period of postponement or withdrawal, register any Company Securities,
other than pursuant to a registration statement on Form S-4 or S-8 (or an
equivalent registration form then in effect). Each Holder of Registrable
Securities agrees that, upon receipt of any notice from the Company that
the Company has determined to withdraw any registration statement pursuant
to clause 2.2(a)(v) above, such Holder will discontinue its disposition of
Registrable Securities pursuant to such registration statement and, if so
directed by the Company, will deliver to the Company all copies, other than
permanent file copies, then in such Holder's possession of the prospectus
covering such Registrable Securities that was in effect at the time of
receipt of such notice. If the Company shall have withdrawn or prematurely
terminated a registration statement filed under Section 2.1 (whether
pursuant to clause 2.2(a)(v) above or as a result of any stop order,
injunction or other order or requirement of the Commission or any other
governmental agency or court), the Company shall not be considered to have
effected an effective registration for the purposes of this Agreement until
the Company shall have filed a new registration statement covering the
Registrable Securities covered by the withdrawn registration statement and
such registration statement shall have been declared effective and shall
not have been withdrawn. If the Company shall give any notice of withdrawal
or postponement of a registration statement, the Company shall file the
applicable registration statement as soon as practicable after the Board of
Directors of the Company determines, in its reasonable business judgment,
that such Valid Business Reason no longer exists (but in no event later
than ninety (90) days after the date of the postponement or withdrawal) and
use its reasonable best efforts to effect the registration under the
Securities Act of the Registrable Securities covered by the withdrawn or
postponed registration statement in accordance with this Section 2.2
(unless the Holder shall have


<PAGE>


                                                                        Page 5

withdrawn its Demand Registration Request, in which case the Company shall
not be considered to have effected an effective registration for the
purposes of this Agreement, such request shall not be counted for purposes
of the Demand Registration Requests to which the Initiating Holders are
entitled pursuant to Section 2.1 and the Company shall pay all Registration
Expenses in connection therewith).

               (c) In the event that any Demand Registration shall involve,
in whole or in part, an underwritten offering, the Initiating Holder shall
select the managing underwriter or underwriters in connection with such
registration, which underwriter(s) shall be of national standing and shall
be reasonably acceptable to the Company.

               (d) Demand Registrations pursuant to Section 2.1 shall be on
an appropriate form of the SEC selected by the Company.

               (e) Holders may not request, and the Company shall not be
obligated, to effect an offering on a delayed or continuous basis pursuant
to Rule 415 (or any successor rule to similar effect) under the Securities
Act.

          2.3. Piggyback Registrations.

               (a) If, at any time, the Company proposes or is required to
register any of its Common Stock under the Securities Act (other than
pursuant to registrations on such form or similar form(s) solely for
registration of securities in connection with an employee benefit plan,
dividend reinvestment plan, or a merger or consolidation or other than
incidental to an issuance of securities intended to be resold under Rule
144A of the Securities Act) on a registration statement on Form S-1, Form
S-2, or Form S-3 (or an equivalent general registration form then in
effect), whether or not for its own account, the Company shall give prompt
written notice of its intention to do so to each of the Holders of record
of Registrable Securities. Upon the written request of any such Holder,
made within twenty (20) days following the receipt of any such written
notice (which request shall specify the maximum number of Registrable
Securities intended to be disposed of by such Holder and the intended
method of distribution thereof), the Company shall, subject to Sections
2.3(b), 2.4, 2.7(b), and 2.8 hereof, include in such filing the Registrable
Securities for which registration is requested by any such Holder and shall
use its reasonable best efforts to cause all such Registrable Securities,
the Holders of which have so requested the registration thereof, to be
registered under the Securities Act on the same terms and conditions as any
Common Stock which the Company at the time proposes to register to permit
the sale or other disposition by the Holders (in accordance with the
intended method of distribution thereof) of the Registrable Securities to
be so registered (each, a "Piggyback Registration"). There is no limitation
on the number of such Piggyback Registrations pursuant to the preceding
sentence which the Company is obligated to effect. No registration effected
under this Section 2.3(a) shall relieve the Company of its obligations to
effect a Demand Registration.

               (b) If, at any time after giving written notice of its
intention to register any Common Stock and prior to the effective date of
the registration statement filed in connection with such registration, the
Company shall determine for any reason not to register or to delay
registration of such Common Stock, the Company may, at its election, give
written notice of such determination to all Holders of record of
Registrable Securities and (i) in the case of a

<PAGE>

                                                                        Page 6

determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such abandoned
registration, without prejudice, however, to the rights of Holders under
Section 2.1 or Section 2.6, and (ii) in the case of a determination to
delay such registration of its equity securities, shall be permitted to
delay the registration of such Registrable Securities for the same period
as the delay in registering such other Common Stock.

               (c) Any Holder shall have the right to withdraw its request
for inclusion of its Registrable Securities in any registration statement
pursuant to this Section 2.3 by giving written notice to the Company of its
request to withdraw; provided, however, that (i) such request must be made
in writing prior to the effective date of such registration statement, and
(ii) such withdrawal shall be irrevocable and, after making such
withdrawal, a Holder shall no longer have any right to include Registrable
Securities in the registration as to which such withdrawal was made.

          2.4. Allocation of Securities Included in Registration Statement.

               (a) If any requested registration pursuant to Section 2.1
involves an underwritten offering and the lead managing underwriter of such
offering (the "Manager") shall advise the Company in writing that, in its
view, the number of securities requested to be included in such
registration by the Holders or any other persons (including those shares of
Common Stock requested by the Company to be included in such registration)
exceeds the largest number (the "Demand Sale Number") that can be sold in
an orderly manner in such offering within a price range acceptable to the
Initiating Holder, the Company shall include in such registration:

                   (i) first, all Registrable Securities requested to be
included in such registration by Holders of Registrable Securities;
provided, however, that, if the number of such Registrable Securities
exceeds the Demand Sale Number, the number of such Registrable Securities
(not to exceed the Demand Sale Number) to be included in such registration
shall be allocated on a pro rata basis among all Holders requesting that
Registrable Securities be included in such registration statement, based on
the number of Registrable Securities then owned by each Holder requesting
inclusion in relation to the number of Registrable Securities owned by all
Holders requesting inclusion;

                   (ii) second, to the extent that the number of
Registrable Securities to be included by all Holders pursuant to clause (i)
of this Section 2.4(a) is less than the Demand Sale Number and in
accordance with Section 2.1(b), securities that the Company proposes to
register; and

                   (iii) third, to the extent that the number of
Registrable Securities to be included by all Holders plus the number of
securities to be included by the Company is less than the Demand Sale
Number and in accordance with Section 2.1(b), any other securities other
than Registrable Securities that the holders thereof propose to register
pursuant to the exercise of piggyback registration rights.

          If, as a result of the proration provisions of this Section
2.4(a), any Holder shall not be entitled to include all Registrable
Securities in a registration that such Holder has requested be included,
such Holder may elect to withdraw his request to include Registrable

<PAGE>

                                                                        Page 7

Securities in such registration or may reduce the number requested to be
included; provided, however, that (x) such request must be made in writing
prior to the earlier of the execution of the underwriting agreement or the
execution of the custody agreement with respect to such registration, and
(y) such withdrawal shall be irrevocable and, after making such withdrawal,
a Holder shall no longer have any right to include Registrable Securities
in the registration as to which such withdrawal was made; provided,
however, that in the event that the Manager subsequently advises the
Company in writing that a larger number of securities may be sold in an
orderly manner in such offering within a price range acceptable to the
Initiating Holder, such withdrawal may be revoked.

               (b) If any registration pursuant to Section 2.3 involves an
underwritten offering and the Manager shall advise the Company in writing
that, in its view, the number of securities requested to be included in
such registration exceeds the number (the "Section 2.3 Sale Number") that
can be sold in an orderly manner in such registration within a price range
acceptable to the Company, the Company shall include in such registration:

                   (i) first, all Common Stock, or securities convertible
into or exchangeable or exercisable for, Common Stock (the "Company
Securities") that the Company proposes to register for its own account;

                   (ii) second, to the extent that the number of Company
Securities to be included pursuant to clause (i) of this Section 2.4(b) is
less than the Section 2.3 Sale Number, all Registrable Securities requested
to be included by all Holders, allocated on a pro rata basis based on the
number of shares of Registrable Securities subject to registration rights
owned by each Holder requesting inclusion in relation to the number of
shares of Registrable Securities subject to registration rights then owned
by all Holders requesting inclusion; and

                   (iii) third, to the extent that the number of Company
Securities, Registrable Securities and other securities to be included
pursuant to clause (ii) of this Section 2.4(b) is less than the Section 2.3
Sale Number, any other securities other than Registrable Securities that
the holders thereof propose to register pursuant to the exercise of
piggyback registration rights.

               2.5. Registration Procedures.

          If and whenever the Company is required by the provisions of this
Agreement to use its reasonable best efforts to effect or cause the
registration of any Registrable Securities under the Securities Act as
provided in this Agreement, the Company shall:

               (a) prepare and file with the Commission a registration
statement on an appropriate registration form of the Commission (and such
amendments and post-effective amendments and supplements to such
registration statement as may be required by the Securities Act) for the
disposition of such Registrable Securities in accordance with the intended
method of disposition thereof, which form shall be selected by the Company
and comply as to form in all material respects with the requirements of the
applicable form, and the Company shall use its reasonable best efforts to
cause such registration statement to become and remain effective, provided,
however, that before filing a registration statement or prospectus or any
amendments

<PAGE>

                                                                        Page 8

or supplements thereto, or comparable statements under securities or blue
sky laws of any jurisdiction, the Company will furnish to one counsel for
the Holders participating in the planned offering (selected by the
Initiating Holder, in the case of a registration pursuant to Sections 2.1,
and selected by the Major Holder, in the case of a registration pursuant to
Section 2.3) and the underwriters, if any, copies of all such documents
proposed to be filed (including all exhibits thereto), which documents will
be subject to the reasonable review and reasonable comment of such counsel;

               (b) prepare and file with the Commission such amendments,
post-effective amendments and supplements to such registration statement
and the prospectus used in connection therewith as may be necessary to keep
such registration statement effective for a period of time as necessary to
complete the offering, which period shall be not less than one hundred
eighty (180) days (or such shorter period that shall terminate when all
Registrable Securities covered by such registration statement have been
sold or withdrawn, but not prior to the expiration of the time period
referred to in Section 4(3) of the Securities Act and Rule 174 thereunder,
if applicable) and comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of
disposition set forth in such registration statement;

               (c) furnish, without charge, to each Selling Holder of such
Registrable Securities and each underwriter, if any, of the securities
covered by such registration statement such number of copies of such
registration statement, each amendment and supplement thereto (in each case
including all exhibits), and the prospectus included in such registration
statement (including each preliminary prospectus) in conformity with the
requirements of the Securities Act, and other documents (including the
documents incorporated by reference in the registration statement), as such
Selling Holder and underwriter may reasonably request in order to
facilitate the public sale or other disposition of the Registrable
Securities owned by such Selling Holder;

               (d) use its reasonable best efforts to register or qualify
the Registrable Securities covered by such registration statement under
such other securities or "blue sky" laws of such jurisdictions as any
Selling Holders or any managing underwriter, if any, shall reasonably
request, provided that in no event shall the Company be required to qualify
to do business as a foreign corporation in any jurisdiction where it would
not, but for the requirements of this paragraph (d), be required to be so
qualified, to subject itself to taxation in any such jurisdiction or to
consent to general service of process in any such jurisdiction;

               (e) promptly notify each Selling Holder covered by such
registration statement and each managing underwriter, if any: (i) when the
registration statement, any pre-effective amendment, the prospectus or any
prospectus supplement related thereto or post-effective amendment to the
registration statement has been filed and, with respect to the registration
statement or any post-effective amendment, when the same has become
effective; (ii) of any request by the Commission or state securities
authority for amendments or supplements to the registration statement or
the prospectus related thereto or for additional information; (iii) of the
issuance by the Commission of any stop order suspending the effectiveness
of the registration statement or the initiation of any proceedings for that
purpose; and (iv) of the receipt by the Company of any notification with
respect to the suspension of the

qualification of any Registrable Securities for sale under the securities
or blue sky laws of any jurisdiction or the initiation of any proceeding
for such purpose;

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

               (g) otherwise use its reasonable best efforts to obtain a
"cold comfort" letter or letters from the Company's independent public
accountants in customary form and covering such matters of the type
customarily covered by "cold comfort" letters as counsel for each Selling
Holder or the managing underwriter, if any, reasonably request;

               (h) otherwise use its reasonable best efforts to furnish, at
the request of each Selling Holder, on the date such Registrable Securities
are delivered to the underwriters for sale pursuant to such registration
or, if such Registrable Securities are not being sold through underwriters
on the date the registration statement with respect to such Registrable
Securities becomes effective, an opinion, dated as of such date, of counsel
representing the Company for the purposes of such registration, addressed
to the underwriters, if any, and to each Selling Holder, covering such
legal matters with respect to the registration as each Selling Holder may
reasonably request and are customarily included in such opinions.

               (i) use its reasonable best efforts to obtain the withdrawal
of any SEC order suspending the effectiveness of the registration statement
and promptly notify each Holder upon obtaining the withdrawal of such
order;

               (j) otherwise use its reasonable best efforts to comply with
all applicable rules and regulations of the Commission;

               (k) cause all such Registrable Securities to be listed on

other securities of the same class issued by the Company are then listed
(subject to notice of issuance), provided, that the applicable listing
requirements are satisfied;

               (l) cooperate with the Selling Holders and the managing
underwriter, if any, to facilitate the timely preparation and delivery of
certificates not bearing any restrictive legends representing the

                                                                        Page 10

agreement prior to any sale of Registrable Securities to the underwriters
or, if not an underwritten offering, in accordance with the instructions of
the Selling Holders;

               (m) make generally available to the Holders an earnings
statement satisfying the provisions of Section 11(a) of the Securities Act
no later than 45 days after the end of the 12-month period (or 90 days if
such period is a fiscal year) beginning with the first day of the Company's
first fiscal quarter commencing after the effective date of a registration
statement, which earnings statement shall cover said 12-month period, and
which requirement will be deemed to be satisfied if the Company timely
files complete and accurate information on Forms 10-Q, 10-K and 8-K under
the Exchange Act and otherwise complies with Rule 158 under the Securities
Act;

               (n) cooperate with each Holder and each underwriter
participating in the disposition of such Registrable Securities and their
respective counsel in connection with any filings required to be made with
the National Association of Securities Dealers, Inc.; and

               (o) during the period when the prospectus is required to be
delivered under the Securities Act, promptly file all documents required to
be filed with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the
Exchange Act.

          The Company may require as a condition precedent to the Company's
obligations under this Section 2.5 that each Selling Holder as to which any
registration is being effected furnish the Company such information
regarding such Selling Holder and the distribution of such securities as
the Company may, from time to time, reasonably request to consummate such
registration.

2.6.     Expenses.The Company shall pay all Registration Expenses in
connection with any registration requested pursuant to this Section 2.
Notwithstanding the foregoing, if (i) a Holder withdraws its Demand
Registration Request under Sections 2.1(c) or (ii) a Holder withdraws its
request for a Piggyback Registration pursuant to Section 2.3(c), then in any
such case such withdrawing Holder shall pay a portion of the Registration
Expenses pro-rated in accordance with the number of such Holder's Registrable
Securities requested to be included in such withdrawn or excluded request,
provided, however, that upon the payment of such expenses by such Holder in
connection with a Demand Registration Request, such Holder shall not be
deemed to have made a Demand Registration; provided, further, that for
purposes of clause (ii) hereof, Registration Expenses shall only include
Registration Expenses incurred through the date of withdrawal of any
Piggyback Registration Request pursuant to Section 2.3(c).

          2.7.     Underwritten Offerings.

               (a) Requested Underwritten Offerings. If requested by the
underwriters for any underwritten offering by the Initiating Holders
pursuant to a registration requested under Section 2.1, the Company shall
enter into a customary underwriting agreement with the managing
underwriter. Such underwriting agreement shall contain such representations
and warranties by, and such other agreements on the part of, the Company
and such other terms and provisions as are customarily contained in
underwriting agreements with respect to secondary distributions, including,
without limitation, provisions relating to indemnification and

<PAGE>

                                                                        Page 11

contribution. The Holders on whose behalf the Registrable Securities are to
be distributed by such underwriters shall be parties to such underwriting
agreement and may, at their option, require that any or all of the
representations and warranties by, and the other agreements on the part of,
the Company to and for the benefit of such underwriters shall also be made
to and for the benefit of such Holders.

               (b) Piggyback Underwritten Offerings. In the case of a
registration pursuant to Section 2.3 hereof, if the Company shall have
determined to enter into any underwriting agreements in connection
therewith, all of the Registrable Securities to be included in such
registration shall be subject to such underwriting agreements. The Holders
may, at their option, require that any or all of the representations and
warranties by, and the other agreements on the part of, the Company to and
for the benefit of such underwriters shall also be made to and for the
benefit of the Holders.

          2.8.     Indemnification.

               (a) Indemnification by the Company. The Company agrees that
in the event of any registration of any Registrable Securities of the
Company under the Securities Act, the Company shall, and hereby does,
indemnify and hold harmless the Holders, their respective directors,
officers, members, partners, agents and Affiliates and each other Person
who participates as an underwriter in the offering or sale of such
securities and each other Person, if any, who controls the Holders or any
such underwriter within the meaning of the Securities Act (collectively,
"Company Indemnitees"), against any losses, claims, damages, or
liabilities, joint or several, to which the Holders or any such director,
officer, member, partner, agent or Affiliate or underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities, joint or several (or actions
or proceedings, whether commenced or threatened, in respect thereof), arise
out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in any registration statement
under which such Registrable Securities were registered under the
Securities Act, any preliminary prospectus, final prospectus or summary
prospectus contained therein, or any amendment or supplement thereto, (ii)
any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein in light
of the circumstances in which they were made not misleading or (iii) any
violation by the Company of the Securities Act or Exchange Act, and, in
each case, the Company shall reimburse the Company Indemnitees for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding, provided, that the Company shall not be liable in any such case
to the Company Indemnitees to the extent that any such loss, claim, damage,
liability (or action or proceeding in respect thereof) or expense arises
out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in such registration statement, any such
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Holders, specifically for
inclusion therein.

               (b) Indemnification by the Holders. As a condition to
including any Registrable Securities in any registration statement, the
Company shall have received an undertaking reasonably satisfactory to it
from each Holder so including any Registrable

<PAGE>

                                                                        Page 12

Securities to severally, but not jointly indemnify and hold harmless (in
the same manner and to the same extent as set forth in paragraph (a) of
this Section 2.8) the Company, and each director of the Company, each
officer of the Company and each other Person, if any, who controls the
Company within the meaning of the Securities Act (collectively "Holder
Indemnitees"), with respect to any statement or alleged statement in or
omission or alleged omission from such registration statement, any
preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, but only to the extent
such statement or alleged statement or omission or alleged omission was
made in reliance upon and in conformity with written information furnished
to the Company by the Holders specifically for inclusion in such
registration statement, preliminary prospectus, final prospectus, summary
prospectus, amendment or supplement. Notwithstanding the provisions of this
Section 2.8(b) or Section 2.8(d), no Holder shall be required to indemnify
any Holder Indemnitee pursuant to this Section 2.8(b) or to contribute
pursuant to Section 2.8(d) in an amount in excess of the amount of the net
proceeds received by such Holder in connection with any such registration
under the Securities Act.

               (c) Notices of Claims, etc. Promptly after receipt by an
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subsections of this Section
2.8, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party, give written notice to the latter of
the commencement of such action or proceeding; provided, however, that the
failure of any indemnified party to give notice as provided herein shall
not relieve the indemnifying party of its obligations under the preceding
subsections of this Section 2.8, except to the extent that the indemnifying
party is actually prejudiced by such failure to give notice, and shall not
relieve the indemnifying party from any liability which it may have to the
indemnified party otherwise than under this Section 2.8. In case any such
action or proceeding is brought against an indemnified party, the
indemnifying party shall be entitled to participate therein and, unless in
the opinion of outside counsel to the indemnified party a conflict of
interest between such indemnified and indemnifying parties may exist in
respect of such claim, to assume the defense thereof, jointly with any
other indemnifying party similarly notified to the extent that it may wish,
with counsel reasonably satisfactory to such indemnified party; provided,
however, that if the defendants in any such action or proceeding include
both the indemnified party and the indemnifying party and if in the opinion
of outside counsel to the indemnified party there may be legal defenses
available to such indemnified party and/or other indemnified parties which
are different from or in addition to those available to the indemnifying
party, the indemnified party or parties shall have the right to select
separate counsel to defend such action or proceeding on behalf of such
indemnified party or parties; provided, however, that the indemnifying
party shall be obligated to pay for only one counsel for all indemnified
parties. After notice from the indemnifying party to such indemnified party
of its election to so assume the defense thereof and approval by the
indemnified party of such counsel, the indemnifying party shall not be
liable to such indemnified party for any legal expenses subsequently
incurred by the latter in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall be liable
for any settlement of any action or proceeding effected without its written
consent. No indemnifying party shall, without the consent of the
indemnified party, consent to entry of any judgment or enter into any
settlement which (i) commits the indemnified party to take, or forebear to
take, any action, (ii) does not include as an unconditional term thereof
the giving by

<PAGE>

                                                                        Page 13

the claimant or plaintiff to such indemnified party of a release from all
liability in respect to such claim or litigation, or (iii) does not relate
solely to monetary damages.

               (d) Contribution. If the indemnification provided for in
this Section 2.8 shall for any reason be held by a court to be unavailable
to an indemnified party under subsection (a) or (b) hereof in respect of
any loss, claim, damage or liability, or any action in respect thereof,
then, in lieu of the amount paid or payable under subsection (a) or (b)
hereof, the indemnified party and the indemnifying party under subsection
(a) or (b) hereof shall contribute to the aggregate losses, claims, damages
and liabilities (including legal or other expenses reasonably incurred in
connection with investigating the same), (i) 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, which resulted in such
loss, claim, damage or liability, or action in respect thereof, with
respect to the statements or omissions which resulted in such loss, claim,
damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations, or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law or if the allocation
provided in this clause (ii) provides a greater amount to the indemnified
party than clause (i) above, in such proportion as shall be appropriate to
reflect not only the relative fault but also the relative benefits received
by the indemnifying party and the indemnified party from the offering of
the securities covered by such registration statement as well as any other
relevant equitable considerations. The Parties hereto agree that it would
not be just and equitable if contributions pursuant to this Section 2.8(d)
were to be determined by pro rata allocation or by any other method of
allocation which does not take into account the equitable considerations
referred to in the preceding sentence of this Section 2.8(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. In addition, no
Person shall be obligated to contribute hereunder any amounts in payment
for any settlement of any action or claim effected without such Person's
consent, which consent shall not be unreasonably withheld. Notwithstanding
the foregoing, if any Holder is the indemnifying party, any contribution
pursuant to this Section 2.8(d) shall be limited to the amount of net
proceeds received by such Holder from the sale of Registrable Securities in
connection with the applicable registration.

               (e) Other Indemnification. Indemnification and contribution
similar to that specified in the preceding subsections of this Section 2.8
(with appropriate modifications) shall be given by the Company and the
Holders with respect to any required registration or other qualification of
securities under any federal, state or blue sky law or regulation of any
governmental authority other than the Securities Act. The indemnification
agreements contained in this Section 2.8 shall be in addition to any other
rights to indemnification or contribution which any indemnified party may
have pursuant to law or contract.

          2.9. Rule 144.With a view to making available to Holders the
benefits of certain rules and regulations of the Commission which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees to use its reasonable best efforts to:

               (a) Make and keep public information available, as those
terms are understood and defined in Commission Rule 144 or any similar or
analogous rule promulgated under the Securities Act; and

<PAGE>

                                                                        Page 14


               (b) File with the Commission, in a timely manner, all
reports and other documents required of the Company under the Exchange Act
and any rules or regulations promulgated thereunder.

          2.10. Limitations on Sale or Distribution of Other Securities. If
requested in writing by the managing underwriter(s), if any, of any
registration effected pursuant to Section 2.1 or 2.3, each Holder of
Registrable Securities agrees not to effect any public sale or
distribution, including, without limitation, any sale pursuant to Rule 144
under the Securities Act, of any Registrable Securities, or any other
equity security of the Company or any security convertible into or
exchangeable or exercisable for any equity security of the Company (other
than as part of such underwritten public offering) during the time period
reasonably requested by the managing underwriters(s), if any.

          2.11. Access to Information.

          So long as Avaya and its Affiliates collectively hold at least 5%
of the outstanding shares of the Company's Common Stock, the Company shall
furnish to Avaya such financial and operating information with respect to
the business and properties of the Company as Avaya shall reasonably
request. The Company's costs and expenses of providing such information
shall be promptly reimbursed by Avaya upon request. Notwithstanding the
foregoing, the Company shall not be obligated to, and shall not, furnish
access to any information which the Company, in its reasonable judgment,
believes (i) to be a trade secret or competitively sensitive information;
(ii) would breach a then existing confidentiality agreement between the
Company and a third party; (iii) if any law, treaty, rule or regulation of
any court or administrative agency restricts such access; or (iv) the
disclosure of such information would have a material adverse effect on the
Company or its subsidiaries. Avaya acknowledges and agrees that Avaya will
have access to material, nonpublic information concerning the Company,
therefore, Avaya agrees that it will not, nor cause another person to,
enter into any agreement, contract, right, or obligation, to buy, sell or
trade any securities of the Company based on any information provided to it
hereunder which is not publicly available, or provide such nonpublic
information to any person under circumstances in which it is reasonably
foreseeable that such person may purchase, sell or trade such securities
resulting in a violation of the Exchange Act, Securities Act or any other
applicable law. Avaya agrees, and agrees to cause its Affiliates and their
respective directors, officers, employees, agents or representatives
(collectively, "Representatives") to maintain the confidentiality of, and
not disclose, any nonpublic information (whether oral, in writing or in any
other form) furnished by the Company, or on behalf of the Company, to Avaya
pursuant to this Section 2.11 (" Confidential Information"); provided,
however, such Confidential Information does not include information which
(i) is or becomes generally available to the public other than as a result
of a disclosure by Avaya or any of its respective Affiliates or
Representatives, or (ii) was or becomes available to Avaya or any of its
respective Affiliates or Representatives on a non-confidential basis from a
source other than the Company or its Affiliates or its Representatives,
provided such source is not bound by a confidentiality agreement with the
Company or its Affiliates or Representatives or otherwise prohibited from
transmitting the Confidential Information by a contractual, legal or
fiduciary obligation. In the event that Avaya is requested or required (by
oral questions, interrogatories, requests for information or

<PAGE>

                                                                        Page 15

documents, subpoena, civil investigative demand or similar process) to
disclose any Confidential Information, it is agreed that Avaya will provide
the Company with prompt notice of each such request so that the Company may
seek an appropriate protective order or other appropriate remedy, or both,
or waive Avaya's compliance with this Section 2.11. It is further agreed
that, if in the absence of a protective order or the receipt of a waiver of
this Section 2.11, Avaya is nonetheless, in the opinion of its counsel,
compelled to disclose information concerning the Company to any tribunal or
else stand liable for contempt or suffer other censure or penalty, Avaya
may furnish only that portion of the Confidential Information which it is
advised by its counsel is legally required to be furnished and shall
exercise its reasonable commercial efforts to obtain reliable assurance
that confidential treatment will be accorded such Confidential Information.
The rights set forth in this Section 2.11, are solely for the benefit of
Avaya and cannot be transferred or assigned to any person without the prior
written consent of the Company, such consent not to be unreasonably
withheld.

          3. GENERAL

          3.1. Governing Law.This Agreement shall be construed and enforced

has been brought in an inconvenient forum.

          3.2. Waiver of Jury Trial.Each of the parties hereto hereby
waives to the fullest extent permitted by applicable law, any right it may
have to a trial by jury in respect of any litigation directly or indirectly
arising out of, under or in connection with this Agreement. Each of the
parties hereto (a) certifies that no representative of any other party has
represented, expressly or otherwise, that such other party would not, in
the event of litigation, seek to enforce the foregoing waiver and (b)
acknowledges that it and the other parties hereto have been induced to
enter into this Agreement by, among other things, the mutual waivers and
certifications in this Section 3.2.

If the Company shall so request, any such successor or assign shall agree
in writing to acquire and hold the Registrable Securities acquired from
