                                    RECITALS

      A. Concurrently with the execution of this Agreement, the Purchaser is
purchasing from the Company a Warrant to Purchase Stock (the "Warrant") pursuant
to which Purchaser has the right to acquire from the Company the Shares (as
defined in the Warrant).

      B. By this Agreement, the Purchaser and the Company desire to set forth
the registration rights of the Shares all as provided herein.

      NOW, THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth, the parties hereto mutually agree as follows:

      1. REGISTRATION RIGHTS. The Company covenants and agrees as follows:

      1.1 DEFINITIONS. For purposes of this Section 1:

      (a) The term "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Securities Act"), and the declaration or ordering of effectiveness of such
registration statement or document;

      (b) The term "Registrable Securities" means (i) those shares of Class A
Common Stock of the Company issuable or issued to Purchaser pursuant to the
Warrant and (ii) any Common Stock of the Company issued as (or issuable upon the
conversion or exercise of any warrant, right or other security which is issued
as) a dividend or other distribution with respect to, or in exchange for or in
replacement of, any stock referred to in (i).

      (c) The terms "Holder" or "Holders" means the Purchaser or qualifying
transferees under subsection 1.8 hereof who hold Registrable Securities.

      (d) The term "SEC" means the Securities and Exchange Commission.

      1.2 COMPANY REGISTRATION.

      (a) Registration. If at any time or from time to time, the Company shall
determine to register any of its securities, for its own account or the account
of any of its shareholders, other than a registration on Form S-8 relating
solely to employee stock option or purchase plans or any successor to such form,
which does not include substantially the same information as would be required
to be included in a registration statement covering the sale of Registrable
Securities, the Company will:

      (i) promptly give to each Holder written notice thereof (which shall
include a list of the jurisdictions in which the Company intends to attempt to
qualify such securities


                                       1
<PAGE>
GREYROCK CAPITAL                                   REGISTRATION RIGHTS AGREEMENT


under the applicable blue sky or other state securities laws); and

      (ii)include in such registration (and compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 30 days after receipt of such written notice from the
Company, by any Holder or Holders, except as set forth in subsection 1.2(b)
below.

      (b) Underwriting. If the registration of which the Company gives notice is
for a registered public offering involving an underwriting, the Company shall so
advise the Holders as a part of the written notice given pursuant to subsection
1.2(a)(i). In such event the right of any Holder to registration pursuant to
this subsection 1.2 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other shareholders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1 to the contrary, if the
underwriter or the Company determines that marketing factors require a
limitation of the number of securities to be underwritten, the underwriter may
exclude some or all of the Registrable Securities from such registration and
underwriting. In the event the number of Registrable Securities to be registered
is limited in accordance with the provisions of this Section 1.2(b), the Company
shall so advise all Holders (except those Holders who have indicated to the
Company their decision not to distribute any of their Registrable Securities
through such underwriting), and the number of shares of the Registrable
Securities that may be included in the registration and underwriting shall be
allocated among such Holders, if available, in proportion, as nearly as
practicable, to the respective amount of the Registrable Securities owned by
such Holders at the time of filing of the registration statement. No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.

      1.3 EXPENSES OF REGISTRATION. All expenses incurred in connection with any
registration, qualification or compliance pursuant to this Section 1 including
without limitation, all registration, filing and qualification fees, printing
expenses, fees and disbursements of counsel for the Company and expenses of any
special audits incidental to or required by such registration, shall be borne by
the Company except the Company shall not be required to pay underwriters' fees,
discounts or commissions relating to Registrable Securities. All expenses of any
registered offering not otherwise borne by the Company shall be borne pro rata
among the Holders participating in the offering and the Company.

      1.4 REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this
Registration Rights Agreement, the Company will keep each Holder participating
therein advised in writing as to the initiation of each registration,
qualification and compliance and as to the completion thereof. Except as
otherwise provided in subsection 1.3, at its expense the Company will:

      (a) Prepare and file with the SEC a registration statement with respect to
such Registrable Securities and use its best efforts to cause such registration
statement to become effective, and, upon the request of the Holders of a
majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to 120 days.

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

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

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

      (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

      (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act or the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

      1.5 INDEMNIFICATION.

      (a) The Company will indemnify each Holder of Registrable Securities and
each of its officers, directors and partners, and each person controlling such
Holder, with respect to which such registration, qualification or compliance has
been effected pursuant to this Rights Agreement, and each underwriter, if any,
and each person who controls any underwriter of the Registrable Securities held
by or issuable to such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereto) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any prospectus, offering circular or other document (including any related
registration statement, notification or the like) incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statement therein not misleading, or any violation or
alleged violation by the Company of the Securities Act, the Securities Exchange
Act of 1934, as amended ("Exchange Act"), or any state securities law applicable
to the Company or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any such state law and relating to action or inaction
required of the Company in connection with any such registration, qualification
of compliance, and will reimburse each such Holder, each of its officers,
directors and partners, and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, within a
reasonable amount of time after incurred for any reasonable legal and any other
expenses incurred in connection with investigating, defending or settling any
such claim, loss, damage, liability or action; provided, however, that the
indemnity agreement contained in this subsection 1.5(a) shall not apply to
amounts paid in settlement of any such claim, loss, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld); and provided further, that the Company will
not be liable in any such case to the extent that any such claim, loss, damage
or liability arises out of or is based on any untrue statement or omission based
upon written information furnished to the Company by an instrument duly executed
by such Holder or underwriter specifically for use therein.

      (b) Each Holder will, if Registrable Securities held by or issuable to
such Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company within the meaning of the Securities Act, and each other such
Holder, each of its officers, directors and partners and each person controlling
such Holder, against all claims, losses, expenses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or 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, and will reimburse
the Company, such Holders, such directors, officers, partners, persons or
underwriters for any reasonable legal or any other expenses incurred in
connection with investigating, defending or settling any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder
specifically for use therein; provided, however, that the indemnity agreement
contained in this subsection 1.5(b) shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability or action if such
settlement is effected without the consent of the Holder (which consent shall
not be unreasonably withheld); and provided further, that the total amount for
which any Holder shall be liable under this subsection 1.5(b) shall not in any
event exceed the aggregate proceeds received by such Holder from the sale of
Registrable Securities held by such Holder in such registration.

      (c) Each party entitled to indemnification under this subsection 1.5 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense; and provided further, that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations hereunder, unless such failure resulted in prejudice to the
Indemnifying Party; and provided further, that an Indemnified Party (together
with all other Indemnified Parties which may be represented without conflict by
one counsel) shall have the right to retain one separate counsel, with the fees
and expenses to be paid by the Indemnifying Party, if representation of such
Indemnified Party by the counsel retained by the Indemnifying Party would be
inappropriate due to actual or potential differing interests between such
Indemnified Party and any other party represented by such counsel in such
proceeding. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of


                                       3
<PAGE>
GREYROCK CAPITAL                                   REGISTRATION RIGHTS AGREEMENT


any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

      1.6 INFORMATION BY HOLDER. Any Holder or Holders of Registrable Securities
included in any registration shall promptly furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to herein.

      1.7 RULE 144 REPORTING. With a view to making available to Holders the
benefits of certain rules and regulations of the SEC which may permit the sale
of the Registrable Securities to the public without registration, the Company
agrees at all times to:

      (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144;

      (b) file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act (at any
time after it has become subject to such reporting requirements); and

      (c) so long as a Holder owns any Registrable Securities, to furnish to
such Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 and of the
Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents so filed
by the Company as the Holder may reasonably request in complying with any rule
or regulation of the SEC allowing the Holder to sell any such securities without
registration.

      1.8 TRANSFER OF REGISTRATION RIGHTS. Holders' rights to cause the Company
to register their securities and keep information available, granted to them by
the Company under subsections 1.2 and 1.7 may be assigned to a transferee or
assignee of a Holder's Registrable Securities not sold to the public, provided,
that the Company is given written notice by such Holder at the time of or within
a reasonable time after said transfer, stating the name and address of said
transferee or assignee and identifying the securities with respect to which such
registration rights are being assigned. The Company may prohibit the transfer of
any Holders' rights under this subsection 1.8 to any proposed transferee or
assignee who the Company reasonably believes is a competitor of the Company.

      1.9 STAND STILL AGREEMENT. Holder hereby agrees that for a period of up to
one hundred eighty (180) days following the effective date of a registration
statement of the Company covering Common Stock (or other securities) to be sold
on its behalf in an underwritten public offering, it shall not, to the extent
requested by the Company or any underwriter, sell or otherwise transfer or
dispose of (other than to transferees who agree to be similarly bound) any
securities of the Company held by Holder at any time during such period except
securities included in such registration. To enforce the foregoing covenant, the
Company may impose stop-transfer instructions with respect to the securities
held by Holder (and the shares or securities of every other person subject to
the foregoing restriction) until the end of such period.

      1.10 TERMINATION OF REGISTRATION RIGHTS. All rights provided for in this
Section 1 will expire on the third anniversary of the Company's initial public
offering. In addition, the rights provided for in this Section 1 shall terminate
as to any Holder once such Holder is free to sell all of its Registrable
Securities to the public pursuant to Rule 144(k).

      2. GENERAL.

      2.1 WAIVERS AND AMENDMENTS. With the written consent of the record or
beneficial holders of at least a majority of the Registrable Securities, the
obligations of the Company and the rights of the Holders of the Registrable
Securities under this agreement may be waived (either generally or in a
particular instance, either retroactively or prospectively, and either for a
specified period of time or indefinitely), and with the same consent the
Company, when authorized by resolution of its Board of Directors, may enter into
a supplementary agreement for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement;
provided, however, that no such modification, amendment or waiver shall reduce
the aforesaid percentage of Registrable Securities. Upon the effectuation of
each such waiver, consent, agreement of amendment or modification, the Company
shall promptly give written notice thereof to the record holders of the
Registrable Securities who have not previously consented thereto in writing.
This Agreement or any provision hereof may be changed, waived, discharged or
terminated only by a statement in writing signed by the party against which
enforcement of the change, waiver, discharge or termination is sought, except to
the extent provided in this subsection 2.1.

      2.2 GOVERNING LAW. This Agreement shall be governed in all respects by the
laws of the State of New York.

      2.3 SUCCESSORS AND ASSIGNS. Except as otherwise expressly provided herein,
the provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors and administrators of the parties hereto.

      2.4 ENTIRE AGREEMENT. Except as set forth below, this Agreement and the
other documents delivered pursuant hereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects
hereof and thereof.

invalid, illegal, or unenforceable, the validity, legality and enforceability of
the remaining provisions of this Agreement or any provision of the other
Agreements shall not in any way be affected or impaired thereby.

      2.7 TITLES AND SUBTITLES. The titles of the sections and subsections of
this Agreement are for convenience of reference only and are not to be

of Purchase (and any assignee or transferee) is fully subordinate to, and shall
not adversely affect, any shareholder rights under the Registration Rights
Agreement, dated as of May 17, 1999, among the Company and the other parties
thereto (as amended from time to time, the "Senior Registration Agreement"). The
Purchaser hereby waives any and all rights hereunder to the extent such rights
in any way adversely affect or interfere in any manner with the rights of the
shareholder under the Senior Registration Agreement. The Shareholders under the
Senior Registration Agreement shall be third party beneficiaries of this Section
entitle to enforce their rights hereunder.
