SECTION 2. RESTRICTION.

     2.1 Demand Registration.

          (a) Subject to the conditions of this Section 2.1, if the Company
shall receive a written request from the Holders of at least fifty percent (50%)
of the Registrable Securities (the "Initiating Holders") that the Company file a
registration statement under the Securities Act covering the registration of at
least twenty percent (20%) of the Registrable Securities then outstanding (or a
lesser percent if the anticipated aggregate offering price, net of underwriting
discounts and commissions, would exceed $5,000,000), then the Company shall,
within thirty (30) days of the receipt thereof, give written notice of such
request to all Holders, and subject to the limitations of this Section 2.1,
effect, as expeditiously as reasonably possible, the registration under the
Securities Act of all Registrable Securities that the Holders request to be
registered.

          (b) If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise the Company as a part of their request made pursuant to this Section 2.1
or any request pursuant to Section 2.3 and the Company shall include such
information in the written notice referred to in Section 2.1(a) or Section
2.3(a), as applicable. In such event, the right of any Holder to include its
Registrable Securities in such registration 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
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by the Company (which underwriter or
underwriters shall be reasonably acceptable to a majority in interest of the
Initiating Holders). Notwithstanding any other provision of this Section 2.1 or
Section 2.3, if the underwriter advises the Company that marketing factors
require a limitation of the number of securities to be underwritten (including
Registrable Securities) then the Company shall so advise all Holders of
Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares that may be included in the underwriting shall be
allocated to the Holders of such Registrable Securities on a pro rata basis
based on the number of Registrable Securities held by all such Holders
(including the Initiating Holders); provided, however, that the number of shares
of Registrable Securities to be included in such underwriting and registration
shall not be reduced unless all other securities of the Company or of those
stockholders permitted to participate in the offering pursuant to the terms of a
Prior Registration Rights Agreement are first entirely excluded from the
underwriting and registration. Any Registrable Securities excluded or withdrawn
from such underwriting shall be withdrawn from the registration.

                                      -3-
<PAGE>

     (c) In the event of dissolution of Forstmann Little or any of its
affiliates then holding Registrable Securities, or in the event that the Company
shall receive an opinion of counsel to Forstmann Little or any of its affiliates
then holding Registrable Securities, in form and substance reasonably
satisfactory to the Company, that the continued ownership of Registrable
Securities by Forstmann Little or any of its affiliates then holding Registrable
Securities would more likely than not: (i) result in a material violation of any
statute, rule, regulation, license, permit or similar approval or order of a
governmental authority that is applicable to Forstmann Little or any of its
affiliates then holding Registrable Securities; or (ii) subject Forstmann Little
or any of its affiliates then holding Registrable Securities to any penalty
material to any such entity under law or of any governmental authority, in any
such case that cannot be cured without a material cost to such entity; or (iii)
impair the "venture capital operating company" status of Forstmann Little or any
of its affiliates then holding such Registrable Securities, then the Company
shall, upon the written request of such entity, file a registration statement
under the Securities Act covering all, but not less than all, of the Registrable
Securities then held by such entity and effect the registration of such
Registrable Securities.

     (d) The Company shall not be required to effect a registration pursuant to
this Section 2.1:

          (i) prior to the date that is one hundred eighty (180) days following
the effective date of the registration statement pertaining to the Initial
Offering;

          (ii) after the Company has effected one (1) registration pursuant to
this Section 2.1, and such registration has been declared or ordered effective
and kept effective by the Company as required by Section 2.5(a) of this
Agreement unless the registration was made pursuant to Section 2.1(c) and
provided, that a demand made pursuant to Section 2.1(c) hereof shall not qualify
as a registration for the purposes of this Section 2(d)(ii).

          (iii) if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 2.1, a certificate signed by the
Chairman of the Board stating that in the good faith and reasonable judgment of
the Board of Directors of the Company, it would be seriously detrimental to the
Company and its stockholders for such registration statement to be effected at
such time, in which event the Company shall have the right to defer such filing
for a period of not more than ninety (90) days after receipt of the request of
the Initiating Holders; provided that such right to delay a request shall be
exercised by the Company not more than once in any twelve (12) month period; or

          (iv) if the Initiating Holders propose to dispose of shares of
Registrable Securities that may be immediately registered on Form S-3 pursuant
to a request made pursuant to Section 2.3 below.

     2.2 Piggyback Registrations. The Company shall notify all Holders of
Registrable Securities in writing at least fifteen (15) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company, but excluding Special Registration Statements and the filing of a
Registration

                                      -4-
<PAGE>

Statement in connection with a Qualified Initial Public Offering) and will
afford each such Holder an opportunity to include in such registration statement
all or part of such Registrable Securities held by such Holder as set forth
herein. Each Holder desiring to include in any such registration statement all
or any part of the Registrable Securities held by it shall, within fifteen (15)
days after the above-described notice from the Company, so notify the Company in
writing. Such notice shall state the intended method of disposition of the
Registrable Securities by such Holder as set forth herein. If a Holder decides
not to include all of its Registrable Securities in any registration statement
thereafter filed by the Company, such Holder shall nevertheless continue to have
the right to include any Registrable Securities in any subsequent registration
statement or registration statements as may be filed by the Company with respect
to offerings of its securities, all upon the terms and conditions set forth
herein.

          (a) Underwriting. If the registration statement under which the
Company gives notice under this Section 2.2 is for an underwritten offering, the
Company shall so advise the Holders of Registrable Securities. In such event,
the right of any such Holder to be included in a registration pursuant to this
Section 2.2 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 Registrable Securities through such underwriting shall 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 the Agreement, if the underwriter determines in good faith that
marketing factors require a limitation of the number of shares to be
underwritten, the number of shares that may be included in the underwriting
shall be allocated first to all stockholders who are entitled to participate and
who have elected to participate in the offering whether pursuant to the terms of
this Agreement or pursuant to the terms of the Prior Registration Rights
Agreements on a pro rata basis based upon the total number of shares held by
each such Participating Stockholder that are subject to piggyback registration
rights pursuant hereto or thereto (the "Prior Securities"); second, to the
Company; and third, to any other stockholder of the Company on a pro rata basis.
Notwithstanding the foregoing, however, no such reduction shall reduce the
amount of securities of the selling Holders included in the registration below
twenty percent (20%) of the aggregate amount of securities of the selling
Holders so requested to be included in such registration, unless such offering
is the Qualified Initial Offering in which event no Holder shall have any right
to participate therein. If any Holder disapproves of the terms of any such
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company and the underwriter, delivered at least ten (10) business days prior
to the effective date of the registration statement. Any Registrable Securities
excluded or withdrawn from such underwriting shall be excluded and withdrawn
from the registration. For any Holder which is a partnership or corporation, the
partners, retired partners, stockholders, subsidiaries, parents and affiliates
of such Holder, or the estates and family members of any such partners and
retired partners and any trusts for the benefit of any of the foregoing person
shall be deemed to be a single "Holder", and any pro rata reduction with respect
to such "Holder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"Holder", as defined in this sentence.

          (b) Right to Terminate Registration. The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 2.2
prior to the

                                      -5-
<PAGE>

effectiveness of such registration whether or not any Holder has elected to
include securities in such registration. The Registration Expenses of such
withdrawn registration shall be borne by the Company in accordance with Section
2.4 hereof.

     2.3 Form S-3 Registration. In case the Company shall receive from any
Holder or Holders of Registrable Securities a written request or requests that
the Company effect a registration on Form S-3 (or any successor to Form S-3) or
any similar short-form registration statement and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company will:

          (a) promptly give written notice of the proposed registration, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

          (b) as soon as practicable, file such registration statement and use
its best efforts to have such registration statement declared effective and
obtain all such qualifications and compliances as may be so requested and as
would permit or facilitate the sale and distribution of all or such portion of
such Holder's or Holders' Registrable Securities as are specified in such
request, together with all or such portion of the Registrable Securities of any
other Holder or Holders joining in such request as are specified in a written
request given within fifteen (15) days after receipt of such written notice from
the Company; provided, however, that the Company shall not be obligated to
effect any such registration, qualification or compliance pursuant to this
Section 2.3:

               (i) if Form S-3 is not available for such offering by the
Holders;

               (ii) if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public of less than one million dollars ($1,000,000);

               (iii) if the Company shall furnish to the Holders a certificate
signed by the Chairman of the Board of Directors of the Company stating that in
the good faith and reasonable judgment of the Board of Directors of the Company,
it would be seriously detrimental to the Company and its stockholders for such
Form S-3 registration to be effected at such time, in which event the Company
shall have the right to defer the filing of the Form S-3 registration statement
for a period of not more than sixty (60) days after receipt of the request of
the Holder or Holders under this Section 2.4; provided, that such right to delay
a request shall be exercised by the Company not more than once in any twelve
(12) month period;

               (iv) after the Company has effected two (2) registrations on Form
S-3 pursuant to this Section 2.3 in any twelve (12) month period, and such
registrations have been declared or ordered effective; or

               (v) in any particular jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance.

                                      -6-
<PAGE>

          (c) Subject to the foregoing, the Company shall file a Form S-3
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. Registrations effected pursuant to this
Section 2.3 shall not be counted as demands for registration or registrations
effected pursuant to Sections 2.1 or 2.2, respectively.

     2.4 Expenses of Registration. Except as specifically provided herein, all
Registration Expenses incurred in connection with any registration,
qualification or compliance hereunder shall be borne by the Company. All Selling
Expenses incurred in connection with any registrations hereunder, shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to
pay for expenses of any registration proceeding begun pursuant to Section 2.1 or
2.3, the request of which has been subsequently withdrawn by the Initiating
Holders unless (a) the withdrawal is based upon material adverse information
concerning the Company that the Company had not publicly revealed at least
forty-eight (48) hours prior to the Initiating Holders request or that the
Company had not otherwise notified the Initiating Holders of at the time of such
request or (b) the Holders of a majority of Registrable Securities agree to
forfeit their right to one requested registration pursuant to Section 2.1 or
Section 2.3, as applicable, in which event such right shall be forfeited by all
Holders). If the Holders are required to pay the Registration Expenses, such
expenses shall be borne by the holders of securities (including Registrable
Securities) requesting such registration in proportion to the number of shares
for which registration was requested. If the Company is required to pay the
Registration Expenses of a withdrawn offering pursuant to clause (a) above, then
the Holders shall not forfeit their rights pursuant to Section 2.1 or Section
2.3.

     2.5 Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

          (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use all commercially reasonable
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 ninety (90)
days or, if earlier, until the Holder or Holders have completed the distribution
related thereto.

          (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 for the period set forth in paragraph (a) above.

          (c) Furnish to the Holders such number 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.

                                      -7-
<PAGE>

          (d) Use its commercially reasonable 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(s) 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 of 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. The Company will use reasonable efforts to amend or supplement such
prospectus in order to cause such prospectus not to include any untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing.

          (g) Use its commercially reasonable efforts to furnish, on the date
that such Registrable Securities are delivered to the underwriters for sale, if
such securities are being sold through underwriters, (i) an opinion, dated as of
such date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and (ii)
a letter dated as of such date, from the independent certified public
accountants of the Company, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten
public offering addressed to the underwriters.

     2.6 Termination of Registration Rights. Except for the registration rights
set forth in Section 2.1(c) hereof, all registration rights granted under this
Section 2 shall terminate and be of no further force and effect seven (7) years
after the date of the Company's Qualified Initial Offering. In addition, a
Holder's registration rights shall expire if (a) the Company has completed its
Initial Offering and is subject to the provisions of the Exchange Act, (b) such
Holder (together with its affiliates, partners and former partners) holds less
than 1% of the Company's outstanding Common Stock (treating all shares of Series
B Preferred Stock on an as converted basis) and (c) all Registrable Securities
held by and issuable to such Holder (and its affiliates, partners, former
partners, members and former members) may be sold under Rule 144 during any
ninety (90) day period.

     2.7 Delay of Registration; Furnishing Information.

          (a) No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Section 2.

                                      -8-
<PAGE>

          (b) It shall be a condition precedent to the obligations of the
Company to take any action pursuant to Section 2.1, 2.2 or 2.3 that the selling
Holders shall furnish to the Company such information regarding themselves, the
Registrable Securities held by them and the intended method of disposition of
such securities as shall be required to effect the registration of their
Registrable Securities.

          (c) The Company shall have no obligation with respect to any
registration requested pursuant to Section 2.1 or Section 2.3 if the number of
shares or the anticipated aggregate offering price of the Registrable Securities
to be included in the registration does not equal or exceed the number of shares
or the anticipated aggregate offering price required to originally trigger the
Company's obligation to initiate such registration as specified in Section 2.1
or Section 2.3, whichever is applicable.

     2.8 Indemnification. In the event any Registrable Securities are included
in a registration statement under Sections 2.1, 2.2 or 2.3:

          (a) The Company will indemnify and hold harmless each Holder, the
partners, officers and directors of each Holder, any underwriter (as defined in
the Securities Act) for such Holder and each person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements, omissions or violations (collectively a
"Violation") by the Company: (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any Violation or alleged
Violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law in connection with the offering
covered by such registration statement (provided, however, that the Company will
not be required to indemnify any of the foregoing persons on account of any
losses, claims, damages or liabilities arising from a Violation if and to the
extent that such Violation was made in a preliminary prospectus and was
corrected in a subsequent prospectus that was required by law to be delivered to
the person making the claim with respect to which indemnification is sought
hereunder, and such subsequent prospectus was made available by the Company to
permit delivery of such prospectus in a timely manner, and such subsequent
prospectus was so delivered to such person); and the Company will pay as
incurred to each such Holder, partner, officer, director, underwriter or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 2.8(a) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Company, which consent shall not be unreasonably withheld,
nor shall the Company be liable in any such case for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon
a Violation which occurs in reliance upon and in conformity with written

                                      -9-
<PAGE>

information furnished expressly for use in connection with such registration by
such Holder, partner, officer, director, underwriter or controlling person of
such Holder.

     (b) Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such registration qualifications or
compliance is being effected, indemnify and hold harmless the Company, each of
its directors, its officers and each person, if any, who controls the Company
within the meaning of the Securities Act, any underwriter and any other Holder
selling securities under such registration statement or any of such other
Holder's partners, directors or officers or any person who controls such Holder,
against any losses, claims, damages or liabilities (joint or several) to which
the Company or any such director, officer, controlling person, underwriter or
other such Holder, or partner, director, officer or controlling person of such
other Holder may become subject under the Securities Act, the Exchange Act or
other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder under an instrument duly executed by such Holder and
stated to be specifically for use in connection with such registration; and each
such Holder will pay as incurred any legal or other expenses reasonably incurred
by the Company or any such director, officer, controlling person, underwriter or
other Holder, or partner, officer, director or controlling person of such other
Holder in connection with investigating or defending any such loss, claim,
damage, liability or action if it is judicially determined that there was such a
Violation; provided, however, that the indemnity agreement contained in this
Section 2.8(b) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Holder, which consent shall not be unreasonably withheld;
provided further, that in no event shall any indemnity under this Section 2.8
exceed the net proceeds from the offering received by such Holder.

     (c) Promptly after receipt by an indemnified party under this Section 2.8
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 2.8, deliver to the indemnifying party
a written notice of the commencement thereof and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
the defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party shall have the right to retain one counsel of
their own, with the reasonable fees and expenses of such counsel 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. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.8, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section 2.8.

     (d) If the indemnification provided for in this Section 2.8 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the Violation(s) that resulted in such loss, claim, damage or
liability, as well as any other relevant equitable considerations. The relative
fault of the indemnifying party and of the indemnified party shall be determined
by a court of law by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission to state a material
fact relates to information supplied by the indemnifying party or by the
indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission;
provided, that in no event shall any contribution by a Holder hereunder exceed
the net proceeds from the offering received by such Holder.

     (e) The obligations of the Company and Holders under this Section 2.8 shall
survive completion of any offering of Registrable Securities in a registration
statement and the termination of this Agreement. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation.

     2.9 Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to this Agreement may be assigned by a
Holder to a transferee or assignee of Registrable Securities to which (a) there
is transferred to such transferee no less than twenty thousand (20,000) shares
of Registrable Securities, appropriately adjusted to reflect any stock splits,
stock dividends, subdivisions, reverse splits and similar events, (b) there is
transferred to such transferee at least ten percent (10%) of the shares of
Registrable Securities held by the Holder, (c) such transferee is an affiliate,
subsidiary or parent company of a party hereto or (d) such transferee or
transferees are partners of a Holder, who agree to act through a single
representative; provided, however, (i) the transferor shall, within ten (10)
days after such transfer, furnish to the Company written notice of the name and
address of such transferee or assignee and the securities with respect to which
such registration rights are being assigned and (ii) such transferee shall agree
to be subject to all restrictions set forth in this Agreement.

     2.10 Amendment of Registration Rights. Any provision of this Section 2 may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and the Holders of a majority of the Registrable
Securities then outstanding. Any amendment or waiver effected in accordance with
this Section 2.10 shall be binding upon each Holder and the Company. By
acceptance of any benefits under this Section 2, Holders of Registrable
Securities hereby agree to be bound by the provisions hereunder.

     2.11 Limitation on Subsequent Registration Rights. After the date of this
Agreement, the Company shall not, without the prior written consent of the
Holders of a majority

                                      -11-
<PAGE>

of the Registrable Securities then outstanding, enter into any agreement with
any holder or prospective holder of any securities of the Company that would
grant such holder registration rights senior to or on parity with those granted
to the Holders hereunder.

     2.12 "Market Stand-Off" Agreement; Agreement to Furnish Information. Each
Holder hereby agrees that such Holder shall not sell, transfer, make any short
sale of, grant any option for the purchase of, or enter into any hedging or
similar transaction with the same economic effect as a sale, any Common Stock
(or other securities) of the Company held by such Holder (other than those
included in the registration) for a period specified by the representative of
the underwriters of Common Stock (or other securities) of the Company not to
exceed one hundred eighty (180) days following the effective date of a
registration statement of the Company filed under the Securities Act with
respect to an Initial Public Offering, Qualified Initial Offering or other
underwritten public offering of the Company's Common Stock; provided that all
officers and directors of the Company and holders of at least five percent (5%)
of the Company's voting securities enter into similar agreements.

     Each Holder agrees to execute and deliver such other agreements as may be
reasonably requested by the Company or the underwriter which are consistent with
the foregoing or which are necessary to give further effect thereto. In
addition, if requested by the Company or the representative of the underwriters
of Common Stock (or other securities) of the Company, each Holder shall provide,
within ten (10) days of such request, such information as may be required by the
Company or such representative in connection with the completion of any public
offering of the Company's securities pursuant to a registration statement filed
under the Securities Act. The obligations described in this Section 2.12 shall
not apply to a registration relating solely to employee benefit plans on Form
S-1 or Form S-8 or similar forms that may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4 or
similar forms that may be promulgated in the future. The Company may impose
stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the foregoing restriction until the end of said one
hundred eighty (180) day period. Each Holder agrees that any transferee of any
shares of Registrable Securities shall be bound by this Section 2.12.

     2.13 Rule 144 Reporting. With a view to making available to the 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 to use its best efforts to:

          (a) Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times after the effective date of
the first registration filed by the Company for an offering of its securities to
the general public;

          (b) File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act; and

          (c) So long as a Holder owns any Registrable Securities, 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 of the Securities
Act, and of the Exchange Act (at

                                      -12-
<PAGE>

any time after it has become subject to such reporting requirements); a copy of
the most recent annual or quarterly report of the Company; and such other
reports and documents as a Holder may reasonably request in availing itself of
any rule or regulation of the SEC allowing it to sell any such securities
without registration.

SECTION 3. MISCELLANEOUS.

     3.1 Governing Law. This Agreement shall be construed under Delaware General
Corporation Law as to matters of corporate law and, as to all other matters of
law, shall be governed and construed under the laws of the State of Delaware as
such laws are applied to agreements between Delaware residents entered into and
performed entirely in the State of Delaware.

     3.2 Survival. The representations, warranties, covenants, and agreements
made herein shall survive any investigation made by any Holder and the closing
of the transactions contemplated hereby. All statements as to factual matters
contained in any certificate or other instrument delivered by or on behalf of
the Company pursuant hereto in connection with the transactions contemplated
hereby shall be deemed to be representations and warranties by the Company
hereunder solely as of the date of such certificate or instrument.

     3.3 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
and shall inure to the benefit of and be enforceable by each person who shall be
a holder of Registrable Securities from time to time; provided, however, that
prior to the receipt by the Company of adequate written notice of the transfer
of any Registrable Securities specifying the full name and address of the
transferee, the Company may deem and treat the person listed as the holder of
such shares in its records as the absolute owner and holder of such shares for
all purposes, including the payment of dividends or any redemption price.

     3.4 Entire Agreement. This Agreement, the Purchase Agreement and the other
documents delivered pursuant thereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects
hereof and no party shall be liable or bound to any other in any manner by any
representations, warranties, covenants and agreements except as specifically set
forth herein and therein.

     3.5 Severability. In the event one or more of the provisions of this
Agreement should, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality, or unenforceability
shall not affect any other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein.

     3.6 Amendment and Waiver.

          (a) Except as otherwise expressly provided, this Agreement may be
amended or modified only upon the written consent of the Company and the holders
of at least a majority of the Registrable Securities.

                                      -13-
<PAGE>

          (b) Except as otherwise expressly provided, the obligations of the
Company and the rights of the Holders under this Agreement may be waived only
with the written consent of the holders of at least a majority of the
Registrable Securities.

          (c) Notwithstanding the foregoing, this Agreement may be amended with
only the written consent of the Company to include additional purchasers of
Shares as "Investors," "Holders" and parties hereto.

          (d) For the purposes of determining the number of Holder or Investors
entitled to vote or exercise any rights hereunder, the Company shall be entitled
to rely solely on the list of record holders of its stock as maintained by or on
behalf of the Company.

     3.7 Delays or Omissions. It is agreed that no delay or omission to exercise
any right, power, or remedy accruing to any Holder, upon any breach, default or
noncompliance of the Company under this Agreement shall impair any such right,
power, or remedy, nor shall it be construed to be a waiver of any such breach,
default or noncompliance, or any acquiescence therein, or of any similar breach,
default or noncompliance thereafter occurring. It is further agreed that any
waiver, permit, consent, or approval of any kind or character on any Holder's
part of any breach, default or noncompliance under the Agreement or any waiver
on such Holder's part of any provisions or conditions of this Agreement must be
in writing and shall be effective only to the extent specifically set forth in
such writing. All remedies, either under this Agreement, by law, or otherwise
afforded to Holders, shall be cumulative and not alternative.

     3.8 Notices. All notices required or permitted hereunder shall be in
writing and shall be deemed effectively given: (a) upon personal delivery to the
party to be notified, (b) when sent by confirmed electronic mail or facsimile if
sent during normal business hours of the recipient; if not, then on the next
business day, (c) five (5) days after having been sent by registered or
certified mail, return receipt requested, postage prepaid, or (d) one (1) day
after deposit with a nationally recognized overnight courier, specifying next
day delivery, with written verification of receipt. All communications shall be
sent to the party to be notified at the address as set forth on the signature
pages hereof or Exhibit A hereto or at such other address as such party may
designate by ten (10) days advance written notice to the other parties hereto.

     3.9 Priority of Registration Rights. Not withstanding anything herein to
the contrary, in the event of any conflict between the provisions of this
Agreement and the provisions of any of the Prior Registration Rights Agreements,
the provisions of this Agreement shall govern.

     3.10 Attorneys' Fees. In the event that any suit or action is instituted to
enforce any provision in this Agreement, the prevailing party in such dispute
shall be entitled to recover from the losing party all fees, costs and expenses
of enforcing any right of such prevailing party under or with respect to this
Agreement, including without limitation, such reasonable fees and expenses of
attorneys and accountants, which shall include, without limitation, all fees,
costs and expenses of appeals.

     3.11 Titles and Subtitles. The titles of the sections and subsections of
this Agreement are for convenience of reference only and are not to be
considered in construing this Agreement.

     3.12 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

     3.13 Mutual Drafting. This Agreement is the result of the joint efforts of
the Company and each of the Investors and each provision hereof has been subject
to the mutual consultation, negotiation and agreement of the parties and there
shall be no construction against any party based on any presumption of the
party's involvement in the drafting thereof.
