promulgated thereunder). Such Registration Statement shall cover to the extent
allowable under the Securities Act and the rules promulgated thereunder

Stock resulting from stock splits, stock dividends or similar transactions with
respect to the Registrable Securities. 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 efforts to cause the Registration Statement to be declared effective

Securities may be sold without any restriction pursuant to Rule 144(k) as

Period"). The Company shall request that the effective time of the Registration
Statement is 4:00 p.m. Eastern Time on the effective date. If at any time and
for any reason, an additional Registration Statement is required to be filed
because at such time the actual number of shares of Common Stock into which the
Warrants are exercisable exceeds the number of shares of Registrable Securities
remaining under the Registration Statement, 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 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-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 and the
Securities Act and the rules promulgated thereunder) in accordance with the plan
of distribution as set forth on Exhibit A hereto and in accordance with
applicable law, 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, 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 (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 the Holders, to conduct a reasonable
review of the documents. 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 shall reasonably object in
writing within five (5) Business Days of their receipt thereof.

                                       4

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be

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 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 to
provide the Holders, within such ten (10) Business Day period, true and complete
copies of all correspondence from and to the Commission relating to the
Registration Statement; (iv) file the final prospectus pursuant to Rule 424 of
the Securities Act no later than 9:00 a.m. Eastern Time on the Business Day
following the date the Registration Statement is declared effective by the
Commission; and (v) 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
Effectiveness 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 as promptly as
possible (and, in the case of (i)(A) below, not less than three (3) Business
Days prior to such filing, and in the case of (iii) below, on the same day of
receipt by the Company of such notice from the Commission) 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 or threatening 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 best efforts to avoid the issuance of, or, if issued,
obtain the withdrawal of, as promptly as possible, (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.

                                       5
<PAGE>

            (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) If requested by any Holder, furnish to such Holder, 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) If requested by any Holder, promptly deliver to each Holder,
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 subject to the provisions of Sections 3(m) and 3(n), 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) If requested by any Holder, prior to any public offering of
Registrable Securities, use its best efforts to register or qualify or cooperate
with the selling Holders 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, to the extent
permitted by the Purchase Agreement and applicable federal and state securities
laws, 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 connection with 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.

                                       6
<PAGE>

            (k) Use its best efforts to cause all Registrable Securities
relating to the Registration Statement to be listed on the Nasdaq Capital Market
or any other securities 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 all documents filed or required to be filed with the Commission.

            (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, Prospectus, or any amendment or supplement thereto, 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.

            Each Holder covenants and agrees that it will not sell any
Registrable Securities under the Registration Statement until the Company has
electronically filed the Prospectus as then amended or supplemented as
contemplated in Section 3(g) and notice from the Company that the Registration
Statement and any post-effective amendments thereto have become effective as
contemplated by Section 3(c).

            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.

                                       7
<PAGE>

            (n) At any time following the date that the Registration Statement
is declared effective by the Commission, if (i) there is material non-public
information regarding the Company which the Company's Board of Directors (the
"Board") 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 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 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 compliance

      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, managers, partners, members, shareholders,
agents, brokers, 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 violation of securities laws or 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 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. 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.

            (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
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 be entitled to 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.

                                       9
<PAGE>

            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 parties 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 one separate counsel at the expense of the
Indemnifying Party, the Indemnifying Party shall not have the right to assume
the defense thereof and the reasonable fees and expenses of 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 or delayed. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, effect any settlement of any pending or threatened Proceeding in respect
of which any Indemnified Party is a party and indemnity has been sought
hereunder, 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 reasonable 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 Indemnified Party shall 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 due but 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 Common Stock 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

                                       10
<PAGE>

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
pursuant to the law.

      6.    Rule 144.

            As long as any Holder owns any Warrants or Registrable Securities,
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, upon the request of any Holder, to promptly furnish such
Holder with true and complete copies of all such filings. As long as any Holder
owns any Warrants or Registrable Securities, 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 and
the 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 relating to such sale
pursuant to Rule 144. 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.

                                       11

      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, such 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, the Commission Documents 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.

            (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) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) Shares or (ii) Warrant Shares, 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 their 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 written notice of such determination and, if within thirty
(30) days after receipt of such notice, or within such shorter period of time as
may be specified by the Company in such written notice as may be necessary for
the Company to comply with its obligations with respect to the timing of the
filing of such registration statement, any such Holder shall so request in
writing (which request shall specify the Registrable Securities intended to be
disposed of by the Purchasers), 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

                                       12
<PAGE>

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 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 (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 shall not represent a greater fraction of the number of Registrable
securities intended to be offered by the Holders 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 (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 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 with the
time periods set forth in Section 2), 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

                                       13
<PAGE>

Period, without being succeeded promptly by a subsequent Registration Statement
filed with and declared effective by the Commission in accordance with Section 2
hereof, 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 Capital Market (or other principal exchange on which the Common Stock is
listed or traded) for any reason for more than three (3) Business Days in the
aggregate without subsequent listing on another exchange or the quotation of the
Common Stock on the OTC Bulletin Board (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 in cash as liquidated damages to
each Holder equal to one percent (1%) for each calendar month (prorated for
shorter periods) of the Holder's initial investment in the Shares from the Event
Date, less any number of Shares that have been sold by such Holder, until the
applicable Event is cured; provided, however, that in no event shall the amount
of liquidated damages payable at any time and from time to time to any Holder
pursuant to this Section 7(e) exceed an aggregate of eighteen percent (18%) of
the amount of the Holder's initial investment in the Shares. Notwithstanding
anything to the contrary in this paragraph (e), if (i) any of the Events
described in clauses (A), (B), (C), (D) or (F) 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(e) shall be payable on the first (1st) Business Day of each thirty (30) day
period following the Event Date. Notwithstanding anything to the contrary
contained herein, in no event shall any liquidated damages be payable with
respect to the Warrants or the Warrant Shares.

            (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
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
(evidenced by a successful transmission) at the 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 transmission, if such notice or
communication is delivered via facsimile at the 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 overnight delivery 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 I attached hereto with copies to its legal counsel named therein, or
with respect to the Company, addressed to:

            (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 Person of all or a portion of the
Shares or 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.

                                       15
<PAGE>

            (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 and
shall become effective when counterparts have been signed by each party and
delivered to the other parties hereto, it being understood that all parties need
not sign the same counterpart. 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; 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(k) shall affect or limit any right to
serve process in any other manner permitted by law. The Company and the Holders
hereby agree that the prevailing party in any suit, action or proceeding arising
out of or relating to this Agreement or the Purchase Agreement, shall be
entitled to reimbursement for reasonable legal fees from the non-prevailing
party. The parties hereby waive all rights to a trial by jury.

            (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.

                                       16
<PAGE>

            (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
the decision of each Purchaser to purchase Securities pursuant to the Purchase
Agreement has been made by such Purchaser independently of any other Purchaser
and independently of any information, materials, statements or opinions as to
the business, affairs, operations, assets, properties, liabilities, results of
operations, condition (financial or otherwise) or prospects of the Company or of
its Subsidiaries which may have made or given by any other Purchaser or by any
agent or employee of any other Purchaser, and no Purchaser or any of its agents
or employees shall have any liability to any Purchaser (or any other person)
relating to or arising from any such information, materials, statements or
opinions. 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 the placement agent and
such counsel does not represent the Purchasers and the Purchasers have retained
their own individual counsel with respect to the transactions contemplated
hereby. 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.

                                    Exhibit A
                              Plan of Distribution

      The selling security holders and any of their pledgees, donees, assignees
and successors-in-interest may, from time to time, sell any or all of their
shares of common stock being offered under this prospectus on any stock
exchange, market or trading facility on which shares of our common stock are
traded or in private transactions. These sales may be at fixed or negotiated
prices. The selling security holders may use any one or more of the following
methods when disposing of shares:

      o     ordinary brokerage transactions and transactions in which the
            broker-dealer solicits purchasers;

      o     block trades in which the broker-dealer will attempt to sell the
            shares as agent but may position and resell a portion of the block
            as principal to facilitate the transaction;

      o     purchases by a broker-dealer as principal and resales by the
            broker-dealer for its account;

      o     an exchange distribution in accordance with the rules of the
            applicable exchange;

      o     privately negotiated transactions;

      o     to cover short sales made after the date that the registration
            statement of which this prospectus is a part is declared effective
            by the Commission;

      o     broker-dealers may agree with the selling security holders to sell a
            specified number of such shares at a stipulated price per share;

      o     a combination of any of these methods of sale; and

      o     any other method permitted pursuant to applicable law.

      The shares may also be sold under Rule 144 under the Securities Act of
1933, as amended ("Securities Act"), if available, rather than under this
prospectus. The selling security holders have the sole and absolute discretion
not to accept any purchase offer or make any sale of shares if they deem the
purchase price to be unsatisfactory at any particular time.

      The selling security holders may pledge their shares to their brokers
under the margin provisions of customer agreements. If a selling security holder
defaults on a margin loan, the broker may, from time to time, offer and sell the
pledged shares.

      Broker-dealers engaged by the selling security holders may arrange for
other broker-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the selling security holders (or, if any
broker-dealer acts as agent for the purchaser of shares, from the purchaser) in
amounts to be negotiated, which commissions as to a particular broker or dealer
may be in excess of customary commissions to the extent permitted by applicable
law.

      If sales of shares offered under this prospectus are made to
broker-dealers as principals, we would be required to file a post-effective
amendment to the registration statement of which this prospectus is a part. In
the post-effective amendment, we would be required to disclose the names of any
participating broker-dealers and the compensation arrangements relating to such
sales.

      The selling security holders and any broker-dealers or agents that are
involved in selling the shares offered under this prospectus may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with these
sales. Commissions received by these broker-dealers or agents and any profit on
the resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act. Any broker-dealers or agents
that are deemed to be underwriters may not sell shares offered under this
prospectus unless and until we set forth the names of the underwriters and the
material details of their underwriting arrangements in a supplement to this
prospectus or, if required, in a replacement prospectus included in a
post-effective amendment to the registration statement of which this prospectus
is a part.

      The selling security holders and any other persons participating in the
sale or distribution of the shares offered under this prospectus will be subject
to applicable provisions of the Exchange Act, and the rules and regulations
under that act, including Regulation M. These provisions may restrict activities
of, and limit the timing of purchases and sales of any of the shares by, the
selling security holders or any other person. Furthermore, under Regulation M,
persons engaged in a distribution of securities are prohibited from
simultaneously engaging in market making and other activities with respect to
those securities for a specified period of time prior to the commencement of
such distributions, subject to specified exceptions or exemptions. All of these
limitations may affect the marketability of the shares.

      If any of the shares of common stock offered for sale pursuant to this
prospectus are transferred other than pursuant to a sale under this prospectus,
then subsequent holders could not use this prospectus until a post-effective
amendment or prospectus supplement is filed, naming such holders. We offer no
assurance as to whether any of the selling security holders will sell all or any
portion of the shares offered under this prospectus.

      We have agreed to pay all fees and expenses we incur incident to the
registration of the shares being offered under this prospectus. However, each
selling security holder and purchaser is responsible for paying any discounts,
commissions and similar selling expenses they incur.

      We and the selling security holders have agreed to indemnify one another
against certain losses, damages and liabilities arising in connection with this
prospectus, including liabilities under the Securities Act.
