contrary, if the actual number of shares of Common Stock issuable upon exercise
of the Warrants exceeds one hundred percent (100%) of the number of shares of

be deemed to include such additional shares of Common Stock.

any additional registration statements contemplated by Section 2, including (in
each case) the Prospectus, amendments and supplements to such registration

any event on or prior to the

                                      -3-
<PAGE>

Filing Date, a "shelf" Registration Statement covering all Registrable
Securities for an offering to be made on a continuous basis pursuant to Rule
415. The Registration Statement shall be on Form S-3 (except if the Company is
not then eligible to register for resale the Registrable Securities on Form S-3,
in which case such registration shall be on another appropriate form in
accordance herewith). The Company shall (i) not permit any securities other than
the Registrable Securities to be included in the Registration Statement, (ii)
use its best efforts to cause the Registration Statement to be declared
effective under the Securities Act (including filing with the Commission a
request for acceleration of effectiveness in accordance with Rule 12d1-2
promulgated under the Exchange Act within five (5) Business Days of the date
that the Company is notified (orally or in writing, whichever is earlier) by the
Commission that a Registration Statement will not be "reviewed," or not be
subject to further review) as soon as possible after the filing thereof, but in
any event prior to the Effectiveness Date, and to keep such Registration
Statement continuously effective under the Securities Act until such date as is
the earlier of (x) the date when all Registrable Securities covered by such
Registration Statement have been sold or (y) the date on which the Registrable
Securities may be sold without any restriction pursuant to Rule 144(k) as
determined by the counsel to the Company pursuant to a written opinion letter,
addressed to the Company's transfer agent to such effect (the "Effectiveness
Period"). If an additional Registration Statement is required, for any reason,
to be filed because the actual number of shares of Common Stock into which the
Warrants are exercisable exceeds the number of shares of Common Stock initially
registered in respect of the Warrant Shares based upon the computation on the
Closing Date, the Company shall have twenty (20) Business Days to file such
additional Registration Statement, and the Company shall use its best efforts to
cause such additional Registration Statement to be declared effective by the
Commission as soon as possible, but in no event later than thirty (30) days
after filing.

         3. Registration Procedures.

                  In connection with the Company's registration obligations
hereunder, the Company shall:

                  (a) Prepare and file with the Commission on or prior to the
Filing Date, a Registration Statement on Form S-3 (or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith) in
accordance with the method or methods of distribution thereof as specified by
the Holders (except if otherwise directed by the Holders), and cause the
Registration Statement to become effective and remain effective as provided
herein; provided, however, that not less than five (5) Business Days prior to
the filing of the Registration Statement or any related Prospectus or any
amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall (i) furnish to the Holders
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of such Holders and such Special Counsel, and (ii) at the request of
any Holder cause its officers and directors, counsel and independent certified
public accountants to respond to such inquiries as shall be necessary, in the
reasonable opinion of counsel to such Holders, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file the Registration Statement or any such Prospectus or any amendments or
supplements thereto to which the Holders of a majority of

                                      -4-
<PAGE>

the Registrable Securities or any Special Counsel shall reasonably object in
writing within three (3) Business Days of their receipt thereof.

                  (b) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holders true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holders of Registrable Securities to be sold
and any Special Counsel as promptly as possible (and, in the case of (i)(A)
below, not less than five (5) Business Days prior to such filing) and (if
requested by any such Person) confirm such notice in writing no later than one
(1) Business Day following the day (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is proposed
to be filed; (B) when the Commission notifies the Company whether there will be
a "review" of such Registration Statement and whenever the Commission comments
in writing on such Registration Statement and (C) with respect to the
Registration Statement or any post-effective amendment, when the same has become
effective; (ii) of any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to the Registration
Statement or Prospectus or for additional information; (iii) of the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the
initiation of any Proceedings for that purpose; (iv) if at any time any of the
representations and warranties of the Company contained in any agreement
contemplated hereby ceases to be true and correct in all material respects; (v)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event that makes
any statement made in the Registration Statement or Prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any
material respect or that requires any revisions to the Registration Statement,
Prospectus or other documents so that, in the case of the Registration Statement
or the Prospectus, as the case may be, it will not contain any untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

                                      -5-
<PAGE>

                  The Company shall promptly furnish to Special Counsel, without
charge, (i) any correspondence from the Commission or the Commission's staff to
the Company or its representatives relating to any Registration Statement and
(ii) promptly after the same is prepared and filed with the Commission, a copy
of any written response to the correspondence received from the Commission.

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of, (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) If requested by the Holders of a majority in interest of
the Registrable Securities, (i) promptly incorporate in a Prospectus supplement
or post-effective amendment to the Registration Statement such information as
the Company reasonably agrees should be included therein and (ii) make all
required filings of such Prospectus supplement or such post-effective amendment
as soon as practicable after the Company has received notification of the
matters to be incorporated in such Prospectus supplement or post-effective
amendment.

                  (f) Furnish to each Holder and any Special Counsel, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

                  (g) Promptly deliver to each Holder and any Special Counsel,
without charge, as many copies of the Registration Statement, Prospectus or
Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons may reasonably request; and the Company
hereby consents to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders in connection with the offering and sale
of the Registrable Securities covered by such Prospectus and any amendment or
supplement thereto.

                  (h) Prior to any public offering of Registrable Securities,
use its best efforts to register or qualify or cooperate with the selling
Holders and any Special Counsel in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Holder requests in
writing, to keep each such registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or things necessary or advisable to enable the disposition in such
jurisdictions of the Registrable Securities covered by a Registration Statement;
provided, however, that the Company shall not be required to qualify generally
to do business in any jurisdiction where it is not then so qualified or to take
any action that would subject it to general service of process in any such
jurisdiction where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

                  (i) Cooperate with the Holders to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration

                                      -6-
<PAGE>

Statement,  which certificates shall be free of all restrictive  legends, and to
enable such Registrable Securities to be in such denominations and registered in
such names as any Holder may request at least two (2) Business Days prior to any
sale of Registrable Securities.

                  (j) Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment, including
a post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an 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,
in the light of the circumstances under which they were made, not misleading.

                  (k) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on Nasdaq and any other
securities exchange, quotation system, market or over-the-counter bulletin
board, if any, on which similar securities issued by the Company are then listed
as and when required pursuant to the Purchase Agreement.

                  (l) Comply in all material respects with all applicable rules
and regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than forty-five (45) days after the end of
any twelve (12)-month period (or ninety (90) days after the end of any twelve
(12)-month period if such period is a fiscal year) commencing on the first day
of the first fiscal quarter of the Company after the effective date of the
Registration Statement, which statement shall conform to the requirements of
Rule 158.

                  (m) Require each selling Holder to furnish to the Company
information regarding such Holder and the distribution of such Registrable
Securities as is required by law to be disclosed in the Registration Statement,
and the Company may exclude from such registration the Registrable Securities of
any such Holder who fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

                  If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

                                      -7-
<PAGE>

                  Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv),
3(c)(v) or 3(c)(vi), such Holder will forthwith discontinue disposition of such
Registrable Securities under the Registration Statement until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement contemplated by Section 3(j), or until it is advised in writing (the
"Advice") by the Company that the use of the applicable Prospectus may be
resumed, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by
reference in such Prospectus or Registration Statement.

                  (n) If (i) there is material non-public information regarding
the Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may suspend effectiveness of
a registration statement and suspend the sale of Registrable Securities under a
Registration Statement for a period not to exceed twenty (20) consecutive days,
provided that the Company may not suspend its obligation under this Section 3(n)
for more than forty-five (45) days in the aggregate during any twelve (12) month
period (each, a "Blackout Period"); provided, however, that no such suspension
shall be permitted for consecutive twenty (20) day periods, arising out of the
same set of facts, circumstances or transactions.

                  (o) Within two (2) Business Days after the Registration
Statement which includes the Registrable Securities is ordered effective by the
Commission, the Company shall deliver, and shall cause legal counsel for the
Company to deliver, to the transfer agent for such Registrable Securities (with
copies to the Holders whose Registrable Securities are included in such
Registration Statement) confirmation that the Registration Statement has been
declared effective by the Commission in the form attached hereto as Exhibit A.

         4. Registration Expenses

majority of Registrable Securities may designate)), (ii) printing expenses

any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, and the respective successors, assigns, estate and personal

contained in the Registration Statement, any Prospectus or any form of

prospectus, or arising out of or relating to any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, except to the extent, but only to the extent, that such
untrue statements or omissions are based solely upon information regarding such
Holder furnished in writing to the Company by such Holder expressly for use
therein, which information was reasonably relied on by the Company for use
therein or to the extent that such information relates to such Holder or such
Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. The

transfer of the Registrable Securities by the Holders.

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, the directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents and employees of such controlling Persons,
and the respective successors, assigns, estate and personal representatives of
each of the foregoing, to the fullest extent permitted by applicable law, from
and against all Losses, as incurred, arising solely out of or based solely upon
any untrue statement of a material fact contained in the Registration Statement,
any Prospectus, or any form of prospectus, or arising solely out of or based
solely upon any omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, to the extent, but only to the extent,
that such untrue statement or omission is contained in or omitted from any
information so furnished in writing by such Holder to the Company specifically
for inclusion in the Registration Statement or such Prospectus and that such
information was reasonably relied upon by the Company for use in the
Registration Statement, such Prospectus or such form of prospectus or to the
extent that such information relates to such Holder or such Holder's proposed
method of distribution of Registrable Securities and was reviewed and expressly
approved in writing by such Holder expressly for use in the Registration
Statement, such Prospectus or such form of Prospectus Supplement.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable under this Section 5(b) for only that amount as does not exceed the net
proceeds to such Holder as a result of the sale of Registrable Securities
pursuant to such Registration Statement.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party promptly shall notify the
Person from whom indemnity is sought (the "Indemnifying Party) in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably

                                      -10-
<PAGE>

satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party because of a failure or
refusal of a governmental authority to enforce such indemnification in
accordance with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses, in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and Indemnified Party in connection with the
actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such Indemnifying
Party and Indemnified Party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been taken or made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms. Notwithstanding anything to the contrary contained
herein, the Holder shall be liable or required to contribute under this Section
5(c) for only that amount as does not exceed the net proceeds to such Holder as
a result of the sale of Registrable Securities pursuant to such Registration
Statement.

                                      -11-
<PAGE>

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

                  The indemnity and contribution agreements contained in this
Section shall be in addition to (a) any cause of action or similar rights of the
indemnified party against the indemnifying party or others, and (b) any
liabilities the indemnifying party may be subject to pursuant to the law.

         6. Rule 144.

                  As long as any Holder owns Notes, Warrants or Warrant Shares,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act and to promptly furnish the Holders with true and complete copies
of all such filings. As long as any Holder owns Notes, Warrants or Warrant
Shares, if the Company is not required to file reports pursuant to Section 13(a)
or 15(d) of the Exchange Act, it will prepare and furnish to the Holders and
make publicly available in accordance with Rule 144(c) promulgated under the
Securities Act annual and quarterly financial statements, together with a
discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included
in reports required by Section 13(a) or 15(d) of the Exchange Act, as well as
any other information required thereby, in the time period that such filings
would have been required to have been made under the Exchange Act. The Company
further covenants that it will take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such
Person to sell Warrant Shares without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 promulgated under
the Securities Act, including providing any legal opinions of counsel to the
Company referred to in the Purchase Agreement. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements.

         7. Miscellaneous.

                  (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

                                      -12-
<PAGE>

                  (b) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has, as of the date hereof entered into and currently in
effect, nor shall the Company or any of its subsidiaries, on or after the date
of this Agreement, enter into any agreement with respect to its securities that
is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Except as disclosed in or
pursuant to the Purchase Agreement, neither the Company nor any of its
subsidiaries has previously entered into any agreement currently in effect
granting any registration rights with respect to any of its securities to any
Person.

                  (c) No Piggyback on Registrations. Except as set forth on
Schedule 7(c), neither the Company nor any of its security holders (other than
the Holders in such capacity pursuant hereto) may include securities of the
Company (other than the Registrable Securities) in the Registration Statement,
and the Company shall not after the date hereof enter into any agreement
providing such right to any of its security holders, unless the right so granted
is subject in all respects to the prior rights in full of the Holders set forth
herein, and is not otherwise in conflict with the provisions of this Agreement.

                  (d) Piggy-Back Registrations. If at any time when there is not
an effective Registration Statement covering any Registrable Securities, the
Company shall determine to prepare and file with the Commission a registration
statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4
or Form S-8 (each as promulgated under the Securities Act) or its then
equivalents relating to equity securities to be issued solely in connection with
any acquisition of any entity or business or equity securities issuable in
connection with stock option or other employee benefit plans, the Company shall
send to each holder of Registrable Securities written notice of such
determination and, if within thirty (30) days after receipt of such notice, any
such holder shall so request in writing (which request shall specify the
Registrable Securities intended to be disposed of by the Holders), the Company
will cause the registration under the Securities Act of all Registrable
Securities which the Company has been so requested to register by the holder, to
the extent requisite to permit the disposition of the Registrable Securities so
to be registered, provided that if at any time after giving written notice of
its intention to register any securities and prior to the effective date of the
registration statement filed in connection with such registration, the Company
shall determine for any reason not to register or to delay registration of such
securities, the Company may, at its election, give written notice of such
determination to such holder and, thereupon, (i) in the case of a determination
not to register, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation to
pay expenses in accordance with Section 4 hereof), and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Registrable Securities being registered pursuant to this Section 7(d) for the
same period as the delay in registering such other securities. The Company shall
include in such registration statement all or any part of such Registrable
Securities such holder requests to be registered; provided, however, that the
Company shall not be required to register any Registrable Securities pursuant to
this Section 7(d) that are eligible for sale pursuant to Rule 144(k) of the
Securities Act. In the case of an underwritten public offering, if the managing
underwriter(s) or underwriter(s) should reasonably object to the inclusion of
the Registrable Securities in such registration statement, then if the Company
after consultation with the managing underwriter

                                      -13-
<PAGE>

should reasonably determine that the inclusion of such Registrable Securities
would materially adversely affect the offering contemplated in such registration
statement, and, based on such determination, recommends inclusion in such
registration statement of fewer or none of the Registrable Securities of the
Holders, then, as applicable (x) the number of Registrable Securities of the
Holders included in such registration statement shall be reduced pro-rata among
such Holders (based upon the number of Registrable Securities requested to be
included in the registration), if the Company after consultation with the
underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y)
none of the Registrable Securities of the Holders shall be included in such
registration statement, if the Company after consultation with the
underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other
persons or entities as well as the Company, such reduction of the number of
Registrable Securities intended to be offered by the Holders shall not represent
a greater fraction than the fraction of similar reductions imposed on such other
persons or entities (other than the Company).

                  (e) Failure to File Registration Statement and Other Events.
The Company and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Period or
if certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or prior to the
Filing Date, or is not declared effective by the Commission on or prior to the
Effectiveness Date (or in the event an additional Registration Statement is
filed because the actual number of shares of Common Stock into which the
Warrants are exercisable exceeds the number of shares of Common Stock initially
registered is not filed and declared effective within the time periods set forth
in Section 2 hereof), or (ii) the Company fails to file with the Commission a
request for acceleration in accordance with Rule 461 promulgated under the
Securities Act within five (5) Business Days of the date that the Company is
notified (orally or in writing, whichever is earlier) by the Commission that a
Registration Statement will not be "reviewed," or not subject to further review,
or (iii) the Registration Statement is filed with and declared effective by the
Commission but thereafter ceases to be effective as to all Registrable
Securities at any time prior to the expiration of the Effectiveness Period,
without being succeeded immediately by a subsequent Registration Statement filed
with and declared effective by the Commission, or (iv) trading in the Common
Stock shall be suspended or if the Common Stock is delisted from Nasdaq and each
other securities exchange or market on which Registrable Securities are required
hereunder to be listed, for any reason for more than three (3) Business Days in
the aggregate, or (v) the conversion rights of the Holders are suspended for any
reason, including by the Company, or (vi) the Company breaches in a material
respect any covenant or other material term or condition to this Agreement, the
Purchase Agreement (other than a representation or warranty contained therein)
or any other agreement, document, certificate or other instrument delivered in
connection with the transactions contemplated hereby and thereby, and such
breach continues for a period of thirty days after written notice thereof to the
Company, or (vii) the Company has breached Section 3(n) of this Agreement (any
such failure or breach being referred to as an "Event"), the Company shall pay
as liquidated damages for such failure and not as a penalty (the "Liquidated
Damages") to each Holder an amount equal to two percent (2%) of the purchase

                                      -14-
<PAGE>

price paid by the Purchasers for the Notes purchased pursuant to the Purchase
Agreement for each thirty (30) day period following the Event until the earlier
of the date (x) the applicable Event has been cured, or (y) the Company prepays
the amounts owing on the Notes pursuant to the terms thereof, which amount shall
be pro rated for any period less than thirty (30) days (the "Periodic Amount").
Payments to be made pursuant to this Section 7(e) shall be due and payable
immediately upon demand at the option of the Holders in cash or as an accrual to
the amount outstanding under the Notes. The parties agree that the Periodic
Amount represents a reasonable estimate on the part of the parties, as of the
date of this Agreement, of the amount of damages that may be incurred by the
Holders if the Registration Statement is not filed on or prior to the Filing
Date or has not been declared effective by the Commission on or prior to the
Effectiveness Date and maintained in the manner contemplated herein during the
Effectiveness Period or if any other Event as described herein has occurred.

                  (f) Specific Enforcement, Consent to Jurisdiction.

                           (i) The Company and the Holders acknowledge and agree
that irreparable damage would occur in the event that any of the provisions of
this Registration Rights Agreement or the Purchase Agreement were not performed
in accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Registration
Rights Agreement or the Purchase Agreement and to enforce specifically the terms
and provisions hereof or thereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

                           (ii) Each of the Company and the Purchasers (i)
hereby irrevocably submits to the jurisdiction of the United States District
Court for the Southern District of New York and the courts of the State of New
York located in New York county for the purposes of any suit, action or
proceeding arising out of or relating to this Agreement or the Purchase
Agreement and (ii) hereby waives, and agrees not to assert in any such suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. Each of the Company and the Purchasers consents to process being
served in any such suit, action or proceeding by mailing a copy thereof to such
party at the address in effect for notices to it under this Agreement and agrees
that such service shall constitute good and sufficient service of process and
notice thereof. Nothing in this Section 7(f) shall affect or limit any right to
serve process in any other manner permitted by law.

                  (g) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and each of the Holders. Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders and that does not directly or indirectly
affect the rights of other Holders may be given by Holders of at least a
majority of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence

                                      -15-
<PAGE>

may not be amended, modified, or supplemented except in accordance with the
provisions of the immediately preceding sentence.

                  (h) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earlier of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice prior to 5:00 p.m., eastern
standard time, on a Business Day, (ii) the Business Day after the date of

facsimile telephone number specified for notice later than 5:00 p.m., eastern
standard time, on any date and earlier than 11:59 p.m., eastern time, on such
date, (iii) the Business Day following the date of mailing, if sent by
nationally recognized overnight courier service or (iv) actual receipt by the
party to whom such notice is required to be given. The addresses for such
communications shall be with respect to each Holder at its address set forth
under its name on Schedule A attached hereto, or with respect to the Company,
addressed to:

                  (i) Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties and their successors and permitted
assigns and shall inure to the benefit of each Holder and its successors and
assigns. The Company may not assign this Agreement or any of its rights or
obligations hereunder without the prior written consent of each Holder. Each
Holder may assign its rights hereunder in the manner and to the Persons as
permitted under the Purchase Agreement.

                  (j) Assignment of Registration Rights. The rights of each
Holder hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
automatically assignable by each Holder to any transferee of such Holder of all
or a portion of the Notes or Warrants or shares of Registrable Securities if:
(i) the Holder agrees in writing with the transferee or assignee to assign such
rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment, (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b)

                                      -16-
<PAGE>

the securities with respect to which such registration rights are being
transferred or assigned, (iii) following such transfer or assignment the further
disposition of such securities by the transferee or assignees is restricted
under the Securities Act and applicable state securities laws, (iv) at or before
the time the Company receives the written notice contemplated by clause (ii) of
this Section, the transferee or assignee agrees in writing with the Company to
be bound by all of the provisions of this Agreement, and (v) such transfer shall
have been made in accordance with the applicable requirements of the Purchase
Agreement. In addition, each Holder shall have the right to assign its rights
hereunder to any other Person with the prior written consent of the Company,
which consent shall not be unreasonably withheld. The rights to assignment shall
apply to the Holders (and to subsequent) successors and assigns.

                  (k) Counterparts. This Agreement may be executed in any number
of counterparts, each of which when so executed shall be deemed to be an
original and, all of which taken together shall constitute one and the same
Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile signature were the original
thereof.

                  (l) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law thereof. This Agreement shall not be
interpreted or construed with any presumption against the party causing this
Agreement to be drafted.

                  (m) Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

                  (n) Severability. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or
unenforceable in any respect, the remainder of the terms, provisions, covenants
and restrictions set forth herein shall remain in full force and effect and
shall in no way be affected, impaired or invalidated, and the parties hereto
shall use their reasonable efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

                  (o) Headings. The headings herein are for convenience only, do
not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof.

                  (p) Shares Held by the Company and its Affiliates. Whenever
the consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than any Holder or transferees or successors or assigns
thereof if such Holder is deemed to be an Affiliate solely by reason of its
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage and shall not be counted as outstanding.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Registration Rights Agreement to be duly executed by their respective authorized
persons as of the date first indicated above.
