Securities for an offering to be made on a continuous basis pursuant to Rule
415.  The Registration Statement shall be on Form S-1, Form S-2, Form S-3 or

3. Registration Procedures.
   -----------------------

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

           (a)  Prepare and file with the Commission on or prior to the
Filing Date, a Registration Statement on Form S-1, Form S-2 or Form SB-2 (or
if the Company is not then eligible to register for resale the Registrable
Securities on Form S-1, Form S-2 or Form SB-2 such registration shall be on
another appropriate form in accordance herewith) in accordance with the
method or methods of distribution thereof as specified by the Holders (except
if otherwise directed by the Holders), and cause the Registration Statement
to become effective and remain effective as provided herein; provided,
however, that not less than five (5) Business Days prior to the filing of the
Registration Statement or any related Prospectus or any amendment or
supplement thereto (including any document that would be incorporated therein
by reference), the Company shall (i) furnish to the Holders and any Special
Counsel, copies of all such documents proposed to be filed, which documents
(other than those incorporated by reference) will be subject to the review of
such Holders and such Special Counsel, and (ii) cause its officers and
directors, counsel and independent certified public accountants to respond to
such inquiries as shall be necessary, in the reasonable opinion of counsel to
such Holders, to conduct a reasonable investigation within the meaning of the
Securities Act.  The Company shall not file the Registration Statement or any
such Prospectus or any amendments or supplements thereto to which the Holders
of a majority of 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
to any comments received from the Commission with respect to the Registration
Statement or any amendment thereto and as promptly as possible provide the
Holders true and complete copies of all correspondence from and to the
Commission relating to the Registration Statement; and (iv) comply in all
material respects with the provisions of the Securities Act and the Exchange
Act with respect to the disposition of all Registrable Securities covered by
the Registration Statement during the applicable period in accordance with
the intended methods of disposition by the Holders thereof set forth in the
Registration Statement as so amended or in such Prospectus as so
supplemented.

       (c) Notify the Holders of Registrable Securities to be sold and
any Special Counsel as promptly as possible (and, in the case of (i)(A)
below, not less than five (5) days prior to such filing) and (if requested by
any such Person) confirm such notice in writing no later than one (1)
Business Day following the day (i)(A) when a Prospectus or any Prospectus
supplement or post-effective amendment to the Registration Statement is
proposed to be filed; (B) when the Commission notifies the Company whether

-4-
<PAGE>

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 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 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 at least two (2) Business Days prior to any sale of Registrable
Securities.

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

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

       (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 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

-6-
<PAGE>

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 (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 postpone or suspend
filing or effectiveness of a registration statement for a period not to
exceed 20 consecutive days, provided that the Company may not postpone or
suspend its obligation 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.

     4. Registration Expenses.
        ---------------------

        All fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall be borne by the Company

-7-
<PAGE>

Registration Statement.  The fees and expenses referred to in the foregoing
sentence shall include, without limitation, (i) all registration and filing

hereunder to be listed, (B) with respect to filings required to be made with
the National Association of Securities Dealers, Inc. and the NASD Regulation,
Inc. and (C) in compliance with state securities or Blue Sky laws (including,
without limitation, fees and disbursements of counsel for the Holders in
connection with Blue Sky qualifications of the Registrable Securities and
determination of the eligibility of the Registrable Securities for investment
under the laws of such jurisdictions as the Holders of a majority of
Registrable Securities may designate)), (ii) printing expenses (including,
without limitation, expenses of printing certificates for Registrable
Securities and of printing prospectuses if the printing of prospectuses is

associated with the delivery by independent public accountants of a comfort

limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder.

     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 such
untrue statements or omissions are based solely upon information regarding
such Holder furnished in writing to the Company by such Holder expressly for
use therein, which information was reasonably relied on by the Company for

-8-
<PAGE>

use therein or to the extent that such information relates to such Holder or
such Holder's proposed method of distribution of Registrable Securities and
was reviewed and expressly approved in writing by such Holder expressly for
use in the Registration Statement, such Prospectus or such form of Prospectus
or in any amendment or supplement thereto.  The 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, the directors,
officers, agents and employees, each Person who controls the Company (within
the meaning of Section 15 of the Securities Act and Section 20 of the
Exchange Act), and the directors, officers, agents or 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 to the Company
specifically for inclusion in the Registration Statement or such Prospectus
and that such information was reasonably relied upon by the Company for use
in the Registration Statement, such Prospectus or such form of prospectus or
to the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed
and expressly approved in writing by such Holder expressly for use in the
Registration Statement, such Prospectus or such form of Prospectus.

         (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

-9-
<PAGE>

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

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

        (d) Contribution.  If a claim for indemnification under Section 5(a)
or 5(b) is unavailable to an Indemnified Party because of a failure or refusal
of a governmental authority to enforce such indemnification in accordance
with its terms (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a
result of such Losses, in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party and Indemnified Party in connection
with the actions, statements or omissions that resulted in such Losses as
well as any other relevant equitable considerations.  The relative fault of
such Indemnifying Party and Indemnified Party shall be determined by
reference to, among other things, whether any action in question, including
any untrue or alleged untrue statement of a material fact or omission or
alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying, Party or Indemnified Party, and
the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such action, statement or omission.  The
amount paid or payable by a party as a result of any Losses shall be deemed
to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have
been indemnified for such fees or expenses if the indemnification provided
for in this Section was available to such party in accordance with its terms.

     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

     6. Rule 144.
        --------

        As long as any Holder owns Put Shares, Warrants or Warrant Shares,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed
by the Company after the date hereof pursuant to Section 13(a) or 15(d) of
the Exchange Act and to promptly furnish the Holders with true and complete
copies of all such filings.  As long as any Holder owns Put Shares, Warrants
or Warrant Shares, if the Company is not required to file reports pursuant to
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to
the Holders and make publicly available in accordance with Rule 144(c)
promulgated under the Securities Act annual and quarterly financial
statements, together with a discussion and analysis of such financial
statements in form and substance substantially similar to those that would
otherwise be required to be included in reports required by Section 13(a) or
15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been
made under the Exchange Act.  The Company further covenants that it will take
such further action as any Holder may reasonably request, all to the extent
required from time to time to enable such Person to sell Put Shares and
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.

       7. Miscellaneous.
          -------------

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

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

-11-
<PAGE>

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 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) Put 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 of Registrable Securities
written notice of such determination and, if within thirty (30) days after
receipt of such notice, any such holder shall so request in writing, (which
request shall specify the Registrable Securities intended to be disposed of
by the Purchaser), the Company will cause the registration under the
Securities Act of all Registrable Securities which the Company has been so
requested to register by the holder, to the extent requisite to permit the
disposition of the Registrable Securities so to be registered, provided that
if at any time after giving written notice of its intention to register any
securities and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for
any reason not to register or to delay registration of such securities, the
Company may, at its election, give written notice of such determination to
such holder and, thereupon, (i) in the case of a determination not to
register, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration (but not from its obligation
to pay expenses in accordance with Section 4 hereof), and (ii) in the case of
a determination to delay registering, shall be permitted to delay registering
any Registrable Securities being registered pursuant to this Section 7(d) for
the same period as the delay in registering such other securities. The
Company shall include in such registration statement all or any part of such
Registrable Securities such holder requests to be registered; provided,
however, that the Company shall not be required to register any Registrable
Securities pursuant to this Section 7(d) that are eligible for sale pursuant
to Rule 144(k) of the Securities Act.  In the case of an underwritten public
offering, if the managing underwriter(s) or underwriter(s) should reasonably
object to the inclusion of the Registrable Securities in such registration
statement, then if the Company after consultation with the managing
underwriter 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

-12-
<PAGE>

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 Purchaser agree that the Holders will suffer damages if the
Registration Statement is not 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 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 within a reasonable time (but in no event later than thirty (30)
days after the Registration Statement ceased to be effective) by a subsequent
Registration Statement filed with and declared effective by the Commission,
or (B) trading in the Common Stock shall be suspended or if the Common Stock
is delisted from The Nasdaq SmallCap Market or the OTC Bulletin Board for any
reason for more than three (3) consecutive Business Days, provided, however,
this clause (B) shall not apply if the Company is delisted from The Nasdaq
SmallCap Market and is then listed on the OTC Bulletin Board within three (3)
Business Days thereafter, or (C) the Company has breached Section 3(n) (any
such failure or breach being referred to as an "Event," and for purposes of
clause (A) after more than fifteen Business Days, or for purposes of clause
(B) the date on which such three Business Day period is exceeded, being
referred to as an "Event Date"), the Company shall pay in cash as liquidated
damages to each Holder an amount equal to 1% for the first thirty (30) day
period and 2% for each thirty (30) day period thereafter of the aggregate
purchase price of all the Registrable Securities then held by such Holder
pursuant to the Purchase Agreement until the applicable Event has been cured,
which shall be pro rated for any period less than thirty (30) days (the
"Periodic Amount").  Payments to be made pursuant to this Section 7(e) shall
be due and payable immediately upon demand in immediately available funds.
The parties agree that the Periodic Amount represents a reasonable estimate
on the part of the parties, as of the date of this Agreement, of the amount
of damages that may be incurred by the Holders if the Registration Statement
is not maintained in the manner contemplated herein during the Effectiveness
Period or if any other Event as described herein has occurred.

         (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 each of the Holders.  Notwithstanding the foregoing, a waiver
or consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders and that does not directly or

-13-
<PAGE>

indirectly affect the rights of other Holders may be given by Holders of at
least a majority of the Registrable Securities to which such waiver or
consent relates; provided, however, that the provisions of this sentence may
not be amended, modified, or supplemented except in accordance with the
provisions of the immediately preceding sentence.

         (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 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 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 1 attached hereto, 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.  The
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,

-14-
<PAGE>

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.
