<PAGE>

                  (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 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 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) 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 any 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 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, 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.

<PAGE>

                  (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) 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.

                  (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 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.

                                      -5-
<PAGE>

                  (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 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 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 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) Use its reasonable best efforts to cause all Registrable
Securities relating to the Registration Statement to be listed on the Nasdaq
National Market or any other securities exchange, quotation system or market, 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 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) 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.

                                      -6-
<PAGE>

                  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) 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, then the Company may (x) postpone or suspend filing
of a registration statement for a period not to exceed 30 consecutive days or
(y) postpone or suspend effectiveness of a registration statement for a period
not to exceed 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 45 days in the aggregate during any 12 month period; provided,
however, that no such postponement or suspension shall be permitted for
consecutive 20 day periods arising out of the same set of facts, circumstances
or transactions.

     5.           Indemnification.

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
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, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, costs of preparation and attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or relating to any untrue
or alleged untrue statement of a material fact contained in the Registration
Statement, any Prospectus or any form of prospectus or in any amendment or
supplement thereto or in any preliminary 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 (i) such untrue statements or omissions are based
solely upon information regarding such Holder or such other Indemnified Party
furnished in writing to the Company by such Holder expressly for use therein and
(ii) that 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 in the final prospectus (filed pursuant to Rule 424 of the
Securities Act), such 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 Securities to such Person. The Company shall notify the
Holders promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by
this Agreement.

<PAGE>

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, its 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,
to the fullest extent permitted by applicable law, from and against all Losses
(as determined by a court of competent jurisdiction in a 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. 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 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 Shares 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.

<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 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 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 any 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 in writing, all to the extent
required from time to time to enable such Person to sell the 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 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.

                                      -11-
<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 Schedule
2.1(c) of 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. 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.

              (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) 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) Intentionally Omitted.

              (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 Time 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 135th day after the Closing 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 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 (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 promptly 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 the Common Stock is delisted from the
Nasdaq National Market for any reason for more than three 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 five Business Day period is
exceeded, or for purposes of clause (D) after more than fifteen Business Days,
or for purposes of clause (F) the date on which such three Business Day period
is exceeded, being referred to as "Event Date"), the Company shall pay an amount
as liquidated damages to each Holder equal to 3% for the first calendar month
and 1.5% per calendar month thereafter or portion thereof of the Holder's
initial investment in the Shares from the Event Date (provided that, with
respect to the Event described in clause (B), the "first calendar month" shall
be deemed to commence on the 30th day prior to the applicable Event Date) until
the applicable Event is cured; provided, that, liquidated damages for the first
calendar month upon the occurrence of an Event shall be payable in cash only,
and for each calendar month thereafter shall be payable at the Company's option
in cash or shares of Common Stock. Notwithstanding anything to the contrary in
this paragraph (e), if (i) any of the Events described in clauses (A), (B) or
(C) 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. If the Company elects to pay in shares of
Common Stock, the number of such shares of Common Stock to be issued to the
Holders pursuant to this paragraph (e) shall be based on the liquidated damage
amount divided by the average closing bid price of the Common Stock for the five
trading days prior to such Event Date and shall be issuable promptly upon
receipt by the Company of a written demand from a Holder made on or after the
Event Date.

              (f) 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 the Holders of a majority of the Registrable Securities outstanding.

              (g) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing

facsimile telephone number specified for notice prior to 5:00 p.m., New York
City 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., New York
City time, on any date and earlier than 11:59 p.m., New York City 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

or to such other address or addresses or facsimile number or numbers as any such
party may most recently have designated in writing to the other parties hereto
by such notice.

                  (h) 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
Purchaser may assign its rights hereunder in the manner and to the Persons as
permitted under the Purchase Agreement.

                  (i) 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 Affiliate of such Holder or any
other Holder or Affiliate of any other Holder 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. 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.

                  (j) 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.

                  (k) 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.

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

                  (m) 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.

                  (n) 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.

                  (o) 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.

                  (p) 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 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 but only such
Purchaser and the other Purchasers have retained their own individual counsel
with respect to the transactions contemplated hereby. The Company acknowledges
that all Purchasers have been provided with the same terms and Transaction
Documents for the purpose of closing the transaction with multiple Purchasers
and not because it was required or requested to do so by the Purchasers.
