resale of 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-1
(except if the Company is not then eligible to register for resale the
Registrable Securities on Form S-1, in which case such registration shall be on

promulgated thereunder). The Company shall (i) not permit any securities other
than the Registrable Securities and the securities to be listed on Schedule II
hereto to be included in the Registration Statement and (ii) use its best

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
sixty (60) 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-1 (or if the Company is not
then eligible to register for resale the Registrable Securities on Form S-1 such
registration shall be on another appropriate form in accordance with the
Securities Act and the rules promulgated thereunder) in accordance with the
method or methods of distribution thereof as specified by the Holders (except if
otherwise directed by the Holders), and use its reasonable best efforts to 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 the 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) 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 Special
Counsel, to conduct a reasonable investigation within the meaning of the
Securities Act. Unless otherwise advised by outside counsel to the Company, 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 the
Registrable Securities or the Special Counsel shall reasonably object in writing
within three (3) Business Days of their receipt thereof.

                  (b)      (i) 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 as
necessary 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

                                       -4-
<PAGE>

as promptly as possible, but in no event later than ten (10) Business Days, 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 the Special Counsel as promptly as possible (and, in the case of (i)(A)
below, not less than five (5) 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 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.

                  (d)      Use its reasonable 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.

                                       -5-

                  (f)      Furnish to each Holder and the 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 (all of which documents may be furnished in
electronic format).

                  (g)      Promptly deliver to each Holder and the Special
Counsel, without charge, as many copies of the 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 reasonable best efforts to register or qualify or cooperate
with the selling Holders and the 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 Statement, which certificates shall be free
of all restrictive legends (provided that the issuance of such unlegended
certificates is in compliance with applicable securities laws), and to enable
such Registrable Securities to be in such denominations and registered in such
names as any Holder may request in writing 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)      Upon the Company becoming eligible to quote its
Common Stock on the OTC Bulletin Board, use its reasonable best efforts to cause
all Registrable Securities relating to the Registration Statement to be listed
on the OTC Bulletin Board or any other securities

                                       -6-
<PAGE>

exchange, quotation system or market, if any, on which similar securities issued
by the Company are then listed or traded 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 45 days after the end of any
12-month period (or 90 days after the end of any 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)      The Company may 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 unreasonably fails to furnish such
information within a reasonable time after receiving such request.

                  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 or the applicable rules and regulations of the Commission promulgated
thereunder) 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.

                  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), 3(c)(vi) or 3(n), 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, (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or

                                       -7-
<PAGE>

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, or (iii) the Company is required to file a
post-effective amendment to the Registration Statement to incorporate the
Company's quarterly and annual reports and audited financial statements on Forms
10-Q and 10-K, then the Company may (x) postpone or suspend filing of a
registration statement for a period not to exceed thirty (30) consecutive days
or (y) postpone or suspend effectiveness of a registration statement for a
period not to exceed twenty (20) consecutive days; provided that the Company may
not postpone or suspend effectiveness of a registration statement under this
Section 3(n) for more than forty-five (45) days in the aggregate during any
three hundred sixty (360) day period; provided, however, that no such
postponement or suspension shall be permitted for consecutive twenty (20) day
periods arising out of the same set of facts, circumstances or transactions.

         4.       Registration Expenses.

                  All fees and expenses incident to the performance of or

of Common Stock), investment advisors and employees of each of them, each Person

of or relating to any violation of securities laws or untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any

the foregoing indemnity agreement is subject to the condition that, insofar as
it relates to any untrue statement, allegedly untrue statement, omission or
alleged omission made in any preliminary prospectus but eliminated or remedied

indemnity agreement shall not inure to the benefit of any Holder, underwriter,
broker or other Person acting on behalf of holders of the Registrable
Securities, from whom the Person asserting any loss, claim, damage, liability or
expense purchased the Registrable Securities which are the subject thereof, if a
copy of such final prospectus had been made available to such Person and such
Holder, underwriter, broker or other Person acting on behalf of holders of the
Registrable Securities and such final prospectus was not delivered to such
Person with or prior to the written confirmation of the sale of such Registrable

final judgment not subject to appeal or review), 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 any
information so furnished in writing by such Holder or other Indemnifying Party
to the Company specifically for inclusion in the Registration Statement or such
Prospectus.

                                       -9-

Notwithstanding anything to the contrary contained herein, each 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 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 (which shall be reasonably
acceptable to the Indemnifying Party) 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. 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

                                      -10-
<PAGE>

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 benefits received by the Indemnifying Party
on the one hand and the Indemnified Party on the other from the offering of the
Notes and Warrants. If, but only if, the allocation provided by the foregoing
sentence is not permitted by applicable law, the allocation of contribution
shall be made in such proportion as is appropriate to reflect not only the
relative benefits referred to in the foregoing sentence but also the relative
fault, as applicable, 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. In no event shall any selling Holder be
required to contribute an amount under this Section 5(d) in excess of the net
proceeds received by such Holder upon sale of such Holder's Registrable
Securities pursuant to the Registration Statement giving rise to such
contribution obligation.

                  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 are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties. Notwithstanding anything to the contrary contained
herein, the Holders shall be liable under this Section 5(d) 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.

         6.       Rule 144.

                  As long as any Holder owns any Registrable Securities, Notes
or Warrants, 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. The Holders acknowledge that the
Company is in the process of attempting to restate its financial statements for
the years ended December 31, 2003 and 2002 (and the quarterly periods contained
therein) and that the Company cannot

                                      -11-
<PAGE>

determine at this time whether it will be able to complete such restatements in
a reasonable amount of time or at all. The Holders further acknowledge that the
Company has not yet filed reports on Form 10-Q for the quarters ended June 30,
2005 and September 30, 2005 and that the Company expects to file such reports on
Form 10-Q within the next two months. The Holders also acknowledge that they
have been advised by the Company that it will not be able to file its annual
report on Form 10-K for the year ended December 31, 2005 on a timely basis (or
within the applicable grace period). As long as any Holder owns any Registrable
Securities, Notes or Warrants, 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 the Registrable Securities 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 relating to such sale pursuant to Rule 144.

         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.

                  (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 Schedule
2.1(c) of the Purchase Agreement or Schedule II hereto, 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. Without limiting the generality of the foregoing, without the
written consent of the Holders of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any Person the right to request the
Company to register any securities of the Company, under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Holders set forth herein, and are not otherwise in conflict with the
provisions of this Agreement.

                                      -12-
<PAGE>

                  (c)      No Piggyback on Registrations. Neither the Company
nor any of its security holders (other than the Holders in such capacity
pursuant hereto or as disclosed on Schedule 2.1(c) of the Purchase Agreement or
Schedule II hereto) may include securities of the Company in the Registration
Statement, and the Company shall not after the date hereof enter into any
agreement providing such right to any of its securityholders, 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)      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 (A) the Registration Statement is
not filed on or prior to the Filing Date, or (B) the Registration Statement is
not declared effective by the Commission on or prior to the Effectiveness Date,
or (C) the Company fails to file with the Commission a request for acceleration
in accordance with Rule 461 promulgated under the Securities Act within three
(3) 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 (D) 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 (E) the Company has breached Section
3(n), or (F) trading in the Common Stock shall be suspended or if, after initial
quotation of the Common Stock on the OTC Bulletin Board, the Common Stock is no
longer quoted on the OTC Bulletin Board (or listed on another principal exchange
on which the Common Stock is traded) for any reason for more than three (3)
Business Days in the aggregate (any such failure or breach being referred to as
an "Event," and for purposes of clauses (A) and (B) the date on which such Event
occurs, or for purposes of clause (C) the date on which such three (3) Business
Day period is exceeded, or for purposes of clause (D) after more than fifteen
(15) Business Days, or for purposes of clause (F) the date on which such three
(3) Business Day period is exceeded, being referred to as "Event Date"), the
Company shall pay an amount as liquidated damages to each Holder in cash equal
to one percent (1.0%) for each calendar month (prorated for shorter periods) of
the Holder's initial investment in the Notes, from the Event Date until the
applicable Event is cured. Notwithstanding anything to the contrary in this
Section 7(d), if (i) any of the Events described in clauses (A), (B), (C) or (D)
shall have occurred, (ii) on or prior to the applicable Event Date, the Company
shall have exercised its rights under Section 3(n) hereof and (iii) the
postponement or suspension permitted pursuant to such Section 3(n) shall remain
effective as of such applicable Event Date, then the applicable Event Date shall
be deemed instead to occur on the second Business Day following the termination
of such postponement or suspension. Liquidated damages payable by the Company
pursuant to this Section 7(d) shall be payable on the first (1st) business day
of each thirty (30) day period following the Event Date.

                  (e)      Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or

                                      -13-
<PAGE>

consents to departures from the provisions hereof may not be given, unless the
same shall be in writing and signed by the Company and the Holders of
three-fourths (3/4) of the Registrable Securities outstanding.

                  (f)      Notices. Any notice, demand, request, waiver or other
communication required or permitted to be given hereunder shall be in writing
and shall be effective (a) upon hand delivery, telecopy or facsimile at the
address or number designated below (if delivered on a business day during normal
business hours where such notice is to be received), or the first business day
following such delivery (if delivered other than on a business day during normal
business hours where such notice is to be received) or (b) on the second
business day following the date of mailing by express courier service, fully

whichever shall first occur. The addresses for such communications shall be:

to the other party hereto.

                  (g)      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

                                      -14-
<PAGE>

Agreement or any of its rights or obligations hereunder without the prior
written consent of each Holder. Each Purchaser may assign its rights hereunder
in the manner and to the Persons as permitted under the Purchase Agreement.

                  (h)      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 Person of all or a portion of the
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) 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. The rights to assignment shall apply to the Holders (and to
subsequent) successors and assigns.

                  (i)      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.

                  (j)      Governing Law; Jurisdiction. This Agreement shall be
governed by and construed in accordance with the internal laws of the State of
New York, without giving effect to any of the conflicts of law principles which
would result in the application of the substantive law of another jurisdiction.
This Agreement shall not be interpreted or construed with any presumption
against the party causing this Agreement to be drafted. The Company and the
Holders agree that venue for any dispute arising under this Agreement will lie
exclusively in the state or federal courts located in New York County, New York,
and the parties irrevocably waive any right to raise forum non conveniens or any
other argument that New York is not the proper venue. The Company and the
Holders irrevocably consent to personal jurisdiction in the state and federal
courts of the state of New York. The Company and the Holders consent 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(j) shall affect or limit any right
to serve process in any other manner permitted by law. The parties hereby waive
all rights to a trial by jury.

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

                                      -15-
<PAGE>

                  (l)      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.

                  (m)      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.

                  (n)      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.

                  (o)      Independent Nature of Purchasers. The Company
acknowledges that the obligations of each Purchaser under the Transaction
Documents are several and not joint with the obligations of any other Purchaser,
and no Purchaser shall be responsible in any way for the performance of the
obligations of any other Purchaser under the Transaction Documents. The Company
acknowledges that nothing contained herein, or in any Transaction Document, and
no action taken by any Purchaser pursuant hereto or thereto (including, but not
limited to, the (i) inclusion of a Purchaser in the Registration Statement and
(ii) review by, and consent to, such Registration Statement by a Purchaser)
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Purchasers are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Documents. The
Company acknowledges that each Purchaser shall be entitled to independently
protect and enforce its rights, including without limitation, the rights arising
out of this Agreement or out of the other Transaction Documents, and it shall
not be necessary for any other Purchaser to be joined as an additional party in
any proceeding for such purpose. The Company acknowledges that for reasons of
administrative convenience only, the Transaction Documents have been prepared by
counsel for one of the Purchasers and such counsel does not represent all of the
Purchasers. The Company acknowledges that it has elected to provide all
Purchasers with the same terms and Transaction Documents for the convenience of
the Company and not because it was required or requested to do so by the
Purchasers. The Company acknowledges that such procedure with respect to the
Transaction Documents in no way creates a presumption that the Purchasers are in
any way acting in concert or as a group with respect to the Transaction
Documents or the transactions contemplated hereby or thereby.
