SECTION 2. REGISTRATION; RESTRICTIONS ON TRANSFER

         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 a majority of the Series D
Preferred Stock (including holders of a majority of Common Stock issued upon
conversion of the Series D Preferred Stock) Then Outstanding (the "Initiating
Holders") that the Company file a registration statement under the Securities
Act covering the registration of all or a portion of the Registrable Securities
at any time after six months following the date hereof, 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, use
its best efforts to effect, as soon as practicable, 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
and the Company shall include such information in the written notice referred to
in Section 2.1(a). 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

                                       2.

<PAGE>

enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by a majority in interest of the
Initiating Holders (which underwriter or underwriters shall be reasonably
acceptable to the Company). Notwithstanding any other provision of this Section
2.1 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 are first entirely excluded from the
underwriting and registration.

             (c) The Holders shall have no more than two demand registrations
under this Section 2.1.

         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 effected by the Company for securityholders other than
the Holder, but excluding registration statements on Form S-4 or S-8) 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. 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. 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 the Company, second to the Series A Preferred

                                       3.

<PAGE>

Stockholders and third to the Series B, C and D Preferred Stockholders on a PRO
RATA basis based on the total number of securities requested to be included by
the holders of such securities. Any Registrable Securities excluded from such
underwriting shall be excluded from the registration. For any holder of Series
A, B, C or D Preferred Stock which is a partnership or corporation, the
partners, retired partners and shareholders 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 effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. No such
termination by the Company shall affect the rights of the Holders hereunder to
demand registration up to the number of times permitted by Section 2.1 hereof.
The Registration Expenses of such withdrawn registration shall be borne by the
Company in accordance with Section 2.3 hereof.

         2.3 EXPENSES OF REGISTRATION. Except as specifically provided herein,
all Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.1 or 2.2 herein shall be borne
by the Company; PROVIDED that the Company shall only be required to pay
Registration Expenses in connection with one registration pursuant to Section
2.1. 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 2.2, the request of which has been subsequently
withdrawn by the Initiating Holders unless the withdrawal is based upon material
adverse information concerning the Company of which the Initiating Holders were
not aware at the time of such request). 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 to any of its demand registrations.

         2.4 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 reasonable efforts to cause
such registration statement to become effective (provided that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company shall furnish to the counsel selected by the Holders covered by such

                                       4.

<PAGE>

registration statement copies of all such documents proposed to be filed) and,
upon the request of the Holders of a majority of the Registrable Securities
registered thereunder, keep such registration statement effective for up to one
hundred eighty (180) 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.

             (d) use its reasonable 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(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.

             (g) use its best 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.

                                       5.

<PAGE>

             (h) cause all such securities to be listed on each securities
exchange on which similar securities issued by the Company are then listed and,
if not so listed, to be listed on the NASD automated quotation system and, if
listed on the NASD automated quotation system, use its best efforts to secure
designation of all such securities covered by such registration statement as a
NASDAQ national market security within the meaning of Rule 11Aa2-1 of the
Securities and Exchange Commission or, failing that, to secure NASDAQ
authorization for such securities and, without limiting the generality of the
foregoing, to arrange for at least two market makers to register as such with
respect to such securities with the NASD;

             (i) provide a transfer agent and registrar for all such securities
not later than the effective date of such registration statement;

             (j) make available for inspection by any seller of securities, any
underwriter participating in any disposition pursuant to such registration
statement and any attorney, accountant or other agent retained by any such
seller or underwriter, all financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors, employees and independent accountants to supply all information
reasonably requested by any such seller, underwriter, attorney, accountant or
agent in connection with such registration statement;

             (k) otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve months beginning with
the first day of the Company's first full calendar quarter after the effective
date of the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

             (l) permit the Holders which, in its sole and exclusive judgment,
might be deemed to be an underwriter or a controlling person of the Company, to
participate in the preparation of such registration or comparable statement and
to require the insertion therein of material, furnished to the Company in
writing, which in the reasonable judgment of the Holders and its counsel should
be included;

             (m) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Common Stock included in such registration statement for sale in any
jurisdiction, the Company shall use its best efforts promptly to obtain the
withdrawal of such order.

         2.5 DELAY OF REGISTRATION; FURNISHING INFORMATION.

         It shall be a condition precedent to the obligations of the Company to
take any action pursuant to Section 2.1 or 2.2 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.

                                       6.

         2.6 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under Sections 2.1 or 2.2:

             (a) To the extent permitted by law, 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; 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 2.6(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 information furnished expressly for
use in connection with such registration by such Holder, partner, officer,
director, underwriter or controlling person of such Holder.

             (b) To the extent permitted by law, 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

                                       7.

<PAGE>

instrument duly executed by such Holder and stated to be specifically for use in
connection with such registration and which remained in the final prospectus
delivered to the purchaser of such securities; 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; PROVIDED, HOWEVER, that the indemnity agreement contained
in this Section 2.6(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 2.6
exceed the net proceeds from the offering received by such Holder, unless such
liability arises out of or is based upon the intentional misconduct of such
Holder.

             (c) Promptly after receipt by an indemnified party under this
Section 2.6 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 2.9, 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,
together with all other indemnified parties which may be represented without
conflict by one counsel shall have the right to retain its own 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. If such defense is assumed, the indemnifying party shall not be
subject to any liability for settlement made by the indemnified party without
its consent (which consent shall not be unreasonably withheld). 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 2.6, 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 2.6.

             (d) If the indemnification provided for in this Section 2.6 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

                                       8.

<PAGE>

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 proceeds from the offering received by such Holder.

             (e) The obligations of the Company and Holders under this Section
2.6 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.

         2.7 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company
to register Registrable Securities pursuant to this Section 2 may be assigned by
a Holder to a permissible transferee or assignee of Registrable Securities, as
provided in Section 3.3; 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
become a signatory to this Agreement. Unless registered pursuant to the
provisions of this Agreement, the certificate or certificates evidencing the
Registrable Securities shall bear the following legend:

         THESE PREFERRED SHARES AND THE COMMON STOCK UNDERLYING THE CONVERSION
         OF THESE PREFERRED SHARES, HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933, AS AMENDED AND MAY NOT BE SOLD, TRANSFERRED,
         ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNTIL A
         REGISTRATION STATEMENT WITH RESPECT THERETO IS DECLARED AND REMAINS
         EFFECTIVE UNDER SUCH ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL
         FOR THE COMPANY THAT AN EXEMPTION FROM REGISTRATION REQUIREMENTS OF
         SUCH ACT IS AVAILABLE.

         2.8 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 at least a majority of the
Registrable Securities Then Outstanding. Any amendment or waiver effected in
accordance with this Section 2.8 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.

         2.9 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 of the Registrable Securities Then Outstanding, enter into
any agreement with any holder of any securities of the Company authorized on the
date hereof that would grant such holder registration rights senior to those

                                       9.

<PAGE>

granted to the Holders hereunder; provided that the Company, without requiring
any consent hereunder, may grant registration rights PARI PASSU with (but not
senior to) the Holders hereunder to independent third party holders of any newly
authorized class of security.

         2.10 "MARKET STAND-OFF" AGREEMENT; AGREEMENT TO FURNISH INFORMATION.
Each Holder hereby agrees that such Holder shall not sell or otherwise transfer
or dispose of 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;
PROVIDED that all officers and directors of the Company and holders of at least
two percent (2%) 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 2.10 shall
not apply to a registration relating solely to employee benefit plans on 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.

         2.11 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;

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