                    (a) REGISTRATION STATEMENTS.

                    (i) REGISTRABLE SECURITIES. Promptly following the closing
of the purchase and sale of Common Stock and Warrants contemplated by the
Purchase Agreement (the "Closing Date") (but no later than thirty (30) days
after the Closing Date), the Company shall prepare and file with the SEC one
Registration Statement on Form S-3 (or, if Form S-3 is not then available to the
Company, on such form of registration statement as is then available to effect a
registration for resale of the Registrable Securities, subject to the Investors'
consent), covering the resale of the Registrable Securities in an amount equal
to the number of shares of Common Stock issued to the Investors on the Closing
Date plus the number of shares of Common Stock necessary to permit the exercise
in full of the Warrants. Such Registration Statement also shall cover, to the
extent allowable under the 1933 Act and the Rules promulgated thereunder
(including Rule 416), such indeterminate number of additional shares of Common
Stock resulting from stock splits, stock dividends or similar transactions with
respect to the Registrable Securities. The Company shall use its best efforts to
obtain from each person who now has piggyback registration rights a waiver of
those rights with respect to the Registration Statement. Except up to 50,000
shares of Common Stock underlying certain warrants issued by the Company and
identified to the Investors, no securities shall be included in the Registration
Statement without the consent of each Investor. The Registration Statement (and
each amendment or supplement thereto, and each request for acceleration of
effectiveness thereof) shall be provided in accordance with Section 3(c) to the
Investors and their counsel prior to its filing or other submission.

                    (ii) ADDITIONAL REGISTRABLE SECURITIES. Upon the written
demand of any Investor and following the issuance of any additional shares of
Common Stock to such Investor pursuant to Section 7.1, of the Purchase
Agreement, the Company shall prepare and file with the SEC one Registration
Statement on Form S-3 (or, if Form S-3 is not then available to the Company, on
such form of registration statement as is then available to effect a
registration for resale of the Additional Registrable Securities, subject to the
Investor's consent) covering the resale of the Additional Registrable Securities
in an amount equal to the number of shares of Common Stock issued to such
Investor. Such Registration Statement also shall cover, to the extent allowable
under the 1933 Act and the Rules promulgated thereunder (including Rule 416),
such indeterminate number of additional shares of Common Stock resulting from
stock splits, stock dividends or similar transactions with respect to the
Additional Registrable Securities. The Company shall use its best efforts to
obtain from each person who now has piggyback registration rights a waiver of
those rights with respect to the Registration Statement. Except up to 50,000
shares of Common Stock underlying certain warrants issued by the Company and
identified to the Investors, no securities shall be included in the Registration
Statement without the consent of the Investor. The Registration Statement (and
each amendment or supplement thereto, and each request for acceleration of
effectiveness thereof) shall be provided in accordance with Section 3(c) to the
Investor and its counsel prior to its filing or other submission.

                    (b)EXPENSES. The Company will pay all expenses associated
with each registration, including the Investors' reasonable expenses in
connection with the registration but excluding discounts, commissions, fees of
underwriters, selling brokers, dealer managers or similar securities industry
professionals.

                    (c) EFFECTIVENESS.

                    (i) The Company shall use its best efforts to have each
Registration Statement declared effective as soon as practicable. if (A) the
Registration Statement covering Registrable Securities is not declared effective
by the SEC within three (3) months following the Closing Date, or the
Registration Statement covering Additional Registrable Securities is not
declared effective by the SEC within three (3) months following the demand of an
Investor relating to the Additional Registrable Securities covered thereby, or
with respect to either a Registration Statement which is subject to full review
by the SEC staff (which shall not include a "plain English" review), within four
(4) months following the Closing Date or demand, as the case may be (each, a
"Registration Date"), (B) after a Registration Statement has been declared
effective by the SEC, sales cannot be made pursuant to such Registration
Statement for any reason (including without limitation by reason of a stop
order, or the Company's failure to update the Registration Statement) but except
as excused pursuant to subparagraph (ii) below, or (C) the Common Stock
generally or the Registrable Securities specifically are not listed or included
for quotation on the Nasdaq National Market System, the Nasdaq Small Cap Market,
the New York Stock Exchange or the American Stock Exchange, then the Company
will make pro-rata payments to each Investor, as liquidated damages and not as a
penalty, in an amount equal to 2% of the aggregate amount paid by such Investor
on the Closing Date to the Company for shares of Common Stock still held by such
Investor for any month or pro rata for any portion thereof following the
Registration Date during which any of the events described in (A) or (B) or (C)
above occurs and is continuing (the "Blackout Period"), provided, however, that
in the case of the events described in (A) or (B) above with respect only to the
Additional Registrable Securities, such penalty shall equal 2% of the aggregate
market value of such Additional Registrable Securities for the duration of the
Blackout Period. Each such payment shall be due and payable within five (5) days
of the end of each month (or ending portion thereof) of the Blackout Period.
Such payments shall be in partial compensation to the Investors, and shall not
constitute the Investors' exclusive remedy for such events. The Blackout Period
shall terminate upon (x) the effectiveness of the applicable Registration
Statement in the case of (A) and (B) above; (y) listing or inclusion of the
Common Stock on the Nasdaq National Market System, the Nasdaq Small Cap Market,
the New York Stock Exchange or the American Stock Exchange in the case of (C)
above; and (z) in the case of the events described in (A) or (B) above, the
earlier termination of the Registration Period (as defined in Section 3(a)
below). The amounts payable as liquidated damages pursuant to this paragraph
shall be payable, at the option of the Investors, in lawful money of the United
States or in shares of Common Stock at the Market Price (as defined in the
Purchase Agreement), and amounts payable as liquidated damages shall be paid
monthly within two (2) business days of the last day of each month following the
commencement of the Blackout Period until the termination of the Blackout
Period. Amounts payable as liquidated damages hereunder shall cease when an
Investor no longer holds Warrants or Registrable Securities, or Additional
Registrable Securities, as applicable.

                    (ii) For not more than ten (10) consecutive trading days or
for a total of not more than twenty (20) trading days in any twelve (12) month
period, the Company may delay the disclosure of material non-public information
concerning the Company, by terminating or suspending effectiveness of any
registration contemplated by this Section containing such information, the
disclosure of which at the time is not, in the good faith opinion of the
Company, in the best interests of the Company (an "Allowed Delay"); provided,
that the Company shall promptly (a) notify the Investors in writing of the
existence of (but in no event, without the prior written consent of an Investor,
shall the Company disclose to such Investor any of the facts or circumstances
regarding) material non-public information giving rise to an Allowed Delay, and
(b) advise the Investors in writing to cease all sales under the Registration
Statement until the end of the Allowed Delay. The duration of the Restricted
Period provided for in the Purchase Agreement will be extended by the number of
days of any and all Allowed Delays.

                    (d) UNDERWRITTEN OFFERING. If any offering pursuant to a
Registration Statement pursuant to Section 2(a) hereof involves an underwritten
offering, the Company shall have the right to select an investment banker and
manager to administer the offering, which investment banker or manager shall be
reasonably satisfactory to the Investors.

          3. COMPANY OBLIGATIONS. The Company will use its best efforts to
effect the registration of the Registrable Securities and Additional Registrable
Securities in accordance with the terms hereof, and pursuant thereto the Company
will, as expeditiously as possible:

                    (a) use its best efforts to cause such Registration
Statement to become effective and to remain continuously effective for a period
that will terminate upon the earlier of (i) the date on which all Registrable
Securities or Additional Registrable Securities, as the case may be, covered by
such Registration Statement, as amended from time to time, have been sold, and
(ii) the date on which all Registrable Securities or Additional Registrable
Securities, as the case may be, may be sold pursuant to Rule 144(k) (the
"Registration Period");

                    (b) prepare and file with the SEC such amendments and
post-effective amendments to the Registration Statement and the Prospectus as
may be necessary to keep the Registration Statement effective for the period
specified in Section 3(a) and to comply with the provisions of the 1933 Act and
the 1934 Act with respect to the distribution of all Registrable Securities and
Additional Registrable Securities; provided that, at least five (5) business
days prior to the filing of a Registration Statement or Prospectus, or any
amendments or supplements thereto, the Company will furnish to the Investors

the comments of the Investors, which must be received within such five (5)
business day period;

                    (c) permit counsel designated by the Investors to review
each Registration Statement and all amendments and supplements thereto no fewer
than seven (7) days prior to their filing with the SEC and not file any document
to which such counsel reasonably objects;

                    (d) furnish to the Investors and their legal counsel (i)
promptly after the same is prepared and publicly distributed, filed with the

amendment thereto, each preliminary prospectus and Prospectus and each amendment
or supplement thereto, and each letter written by or on behalf of the Company to
the SEC or the staff of the SEC, and each item of correspondence from the SEC or
the staff of the SEC, in each case relating to such Registration Statement
(other than any portion of any thereof which contains information for which the
Company has sought confidential treatment), and (ii) such number of copies of a
Prospectus, including a preliminary prospectus, and all amendments and
supplements thereto and such other documents as each Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities and
Additional Registrable Securities owned by such Investor;

                    (e) in the event the Company selects an underwriter for the
offering, the Company shall enter into and perform its reasonable obligations
under an underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
underwriter of such offering;

                    (f) if required by the underwriter, or if any Investor is
described in the Registration Statement as an underwriter, the Company shall
furnish, on the effective date of the Registration Statement, on the date that
Registrable Securities or Additional Registrable Securities, as applicable, are
delivered to an underwriter, if any, for sale in connection with the
Registration Statement and at periodic intervals thereafter from time to time on
request, (i) an opinion, dated as of such date, from independent legal counsel
representing the Company for purposes of such Registration Statement, in form,

date, from the Company's independent certified public accountants in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriter
and the Investors;

                    (g) make effort to prevent the issuance of any stop order or
other suspension of effectiveness and, if such order is issued, obtain the
withdrawal of any such order at the earliest possible moment;

                    (h) furnish to each Investor at least five copies of the
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules by air mail within two business days of the
effective date thereof;

                    (i) prior to any public offering of Registrable Securities
or Additional Registrable Securities, use its reasonable best efforts to
register or qualify or cooperate with the Investors and their counsel in
connection with the registration or qualification of such Registrable Securities
or Additional Registrable Securities, as applicable, for offer and sale under
the securities or blue sky laws of such jurisdictions requested by the Investor
and do any and all other reasonable acts or things necessary or advisable to
enable the distribution in such jurisdictions of the Registrable Securities or
Additional Registrable Securities covered by the Registration Statement;

                    (j) cause all Registrable Securities or Additional
Registrable Securities covered by a Registration Statement to be listed on each
securities exchange, interdealer quotation system or other market on which
similar securities issued by the Company are then listed;

                    (k) immediately notify the Investors, at any time when a
Prospectus relating to the Registrable Securities or Additional Registrable
Securities is required to be delivered under the Securities Act, upon discovery
that, or upon the happening of any event as a result of which, the Prospectus
included in such Registration Statement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, and at the request of any such holder,
promptly prepare and furnish to such holder a reasonable number of copies of a
supplement to or an amendment of such Prospectus as may be necessary so that, as
thereafter delivered to the purchasers of such Registrable Securities or
Additional Registrable Securities, as applicable, such Prospectus shall not
include 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 not
misleading in the light of the circumstances then existing; and

                    (l) otherwise use its best efforts to comply with all

Date (as defined below), an earnings statement covering a period of at least
twelve months, beginning after the effective date of each Registration
Statement, which earnings statement shall satisfy the provisions of Section
11(a) of the 1933 Act (for the purpose of this subsection 3(l), "Availability
Date" means the 45th day following the end of the fourth fiscal quarter that
includes the effective date of such Registration Statement, except that, if such
fourth fiscal quarter is the last quarter of the Company's fiscal year,
"Availability Date" means the 90th day after the end of such fourth fiscal
quarter).

          4. DUE DILIGENCE REVIEW; INFORMATION. The Company shall make
available, during normal business hours, for inspection and review by the
Investors, advisors to and representatives of the Investors (who may or may not
be affiliated with the Investors and who are reasonably acceptable to the
Company), any underwriter participating in any disposition of Common Stock on
behalf of the Investors pursuant to the Registration Statement or amendments or
supplements thereto or any blue sky, NASD or other filing, all financial and
other records, all SEC Documents and other filings with the SEC, and all other
corporate documents and properties of the Company as may be reasonably necessary
for the purpose of such review, and cause the Company's officers, directors and
employees, within a reasonable time period, to supply all such information
reasonably requested by the Investors or any such representative, advisor or
underwriter in connection with such Registration Statement (including, without
limitation, in response to all questions and other inquiries reasonably made or
submitted by any of them), prior to and from time to time after the filing and
effectiveness of the Registration Statement for the sole purpose of enabling the
Investors and such representatives, advisors and underwriters and their
respective accountants and attorneys to conduct initial and ongoing due
diligence with respect to the Company and the accuracy of the Registration
Statement.


          The Company shall not disclose material nonpublic information to the
Investors, or to advisors to or representatives of the Investors, unless prior
to disclosure of such information the Company identifies such information as
being material nonpublic information and provides the Investors, such advisors
and representatives with the opportunity to accept or refuse to accept such
material nonpublic information for review. The Company may, as a condition to
disclosing any material nonpublic information hereunder, require the Investors'
advisors and representatives to enter into a confidentiality agreement
(including an agreement with such advisors and representatives prohibiting them
from trading in Common Stock during such period of time as they are in
possession of material nonpublic information) in form reasonably satisfactory to
the Company and the Investors. Nothing herein shall require the Company to
disclose material nonpublic information to the Investors or their advisors or
representatives.

          5. OBLIGATIONS OF THE INVESTORS.

                    (a) Each Investor shall furnish in writing to the Company
such information regarding itself, the Registrable Securities or Additional
Registrable Securities, as applicable, held by it and the intended method of
disposition of the Registrable Securities or Additional Registrable Securities,
as applicable, held by it, as shall be reasonably required to effect the
registration of such Registrable Securities or Additional Registrable
Securities, as applicable, and shall execute such documents in connection with
such registration as the Company may reasonably request. At least fifteen (15)
business days prior to the first anticipated filing date of any Registration
Statement, the Company shall notify each Investor of the information the Company
requires from such Investor if such Investor elects to have any of the
Registrable Securities or Additional Registrable Securities included in the
Registration Statement. An Investor shall provide such information to the
Company at least five (5) business days prior to the first anticipated filing
date of such Registration Statement if such Investor elects to have any of the
Registrable Securities or Additional Registrable Securities included in the
Registration Statement.

                    (b) Each Investor, by its acceptance of the Registrable
Securities and Additional Registrable Securities, if any, agrees to cooperate
with the Company as reasonably requested by the Company in connection with the
preparation and filing of a Registration Statement hereunder, unless such
Investor has notified the Company in writing of its election to exclude all of
its Registrable Securities or Additional Registrable Securities, as applicable,
from the Registration Statement.

                    (c) In the event the Company, at the request of the
Investors, determines to engage the services of an underwriter, such Investor
agrees to enter into and perform its obligations under an underwriting
agreement, in usual and customary form, including, without limitation, customary
indemnification and contribution obligations, with the managing underwriter of
such offering and take such other actions as are reasonably required in order to
expedite or facilitate the dispositions of the Registrable Securities or
Additional Registrable Securities, as applicable.

                    (d) Each Investor agrees that, upon receipt of any notice
from the Company of the happening of any event rendering a Registration
Statement no longer effective, such Investor will immediately discontinue
disposition of Registrable Securities or Additional Registrable Securities
pursuant to the Registration Statement covering such Registrable Securities or
Additional Registrable Securities, until the Investor's receipt of the copies of
the supplemented or amended prospectus filed with the SEC and declared effective
and, if so directed by the Company, the Investor shall deliver to the Company
(at the expense of the Company) or destroy (and deliver to the Company a
certificate of destruction) all copies in the Investor's possession of the
prospectus covering the Registrable Securities or Additional Registrable
Securities, as applicable, current at the time of receipt of such notice.

                    (e) No Investor may participate in any third party
underwritten registration hereunder unless it (i) agrees to sell the Registrable
Securities or Additional Registrable Securities, as applicable, on the basis
provided in any underwriting arrangements in usual and customary form entered
into by the Company, (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements, and (iii) agrees to
pay its pro rata share of all underwriting discounts and commissions and any
expenses in excess of those payable by the Company pursuant to the terms of this
Agreement.

         6. INDEMNIFICATION.

                    (a) INDEMNIFICATION BY COMPANY. The Company agrees to
indemnify and hold harmless, to the fullest extent permitted by law the
Investors, each of their officers, directors, partners and employees and each
person who controls the Investors (within the meaning of the 1933 Act) against
all losses, claims, damages, liabilities, costs (including, without limitation,
reasonable attorney's fees) and expenses imposed on such person caused by (i)
any untrue or alleged untrue statement of a material fact contained in any
Registration Statement, Prospectus or any preliminary prospectus or any
amendment or supplement thereto or any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as the same are based upon any
information furnished in writing to the Company by such Investors, expressly for
use therein, or (ii) any violation by the Company of any federal, state or
common law, rule or regulation applicable to the Company in connection with any
Registration Statement, Prospectus or any preliminary prospectus, or any
amendment or supplement thereto, and shall reimburse in accordance with
subparagraph (c) below, each of the foregoing persons for any legal and any
other expenses reasonably incurred in connection with investigating or defending
any such claims. The foregoing is subject to the condition that, insofar as the
foregoing indemnities relate to any untrue statement, alleged untrue statement,
omission or alleged omission made in any preliminary prospectus or Prospectus
that is eliminated or remedied in any Prospectus or amendment or supplement
thereto, the above indemnity obligations of the Company shall not inure to the
benefit of any indemnified party if a copy of such corrected Prospectus or
amendment or supplement thereto had been made available to such indemnified
party and was not sent or given by such indemnified party at or prior to the
time such action was required of such indemnified party by the 1933 Act and if
delivery of such Prospectus or amendment or supplement thereto would have
eliminated (or been a sufficient defense to) any liability of such indemnified
party with respect to such statement or omission. Indemnity under this Section
5(a) shall remain in full force and effect regardless of any investigation made
by or on behalf of any indemnified party and shall survive the permitted
transfer of the Registrable Securities and Additional Registrable Securities.

                    (b) INDEMNIFICATION BY HOLDER. In connection with any
registration pursuant to the terms of this Agreement, each Investor will furnish
to the Company in writing such information as the Company reasonably requests
concerning the holders of Registrable Securities and Additional Registrable
Securities or the proposed manner of distribution for use in connection with any
Registration Statement or Prospectus and agrees, severally but not jointly, to
indemnify and hold harmless, to the fullest extent permitted by law, the
Company, its directors, officers, employees, stockholders and each person who
controls the Company (within the meaning of the 1933 Act) against any losses,
claims, damages, liabilities and expense (including reasonable attorney's fees)
resulting from any untrue statement of a material fact or any omission of a
material fact required to be stated in the Registration Statement or Prospectus
or preliminary prospectus or amendment or supplement thereto or necessary to
make the statements therein not misleading, to the extent, but only to the
extent that such untrue statement or omission is contained in any information
furnished in writing by such Investor to the Company specifically for inclusion
in such Registration Statement or Prospectus or amendment or supplement thereto
and that such information was substantially relied upon by the Company in
preparation of the Registration Statement or Prospectus or any amendment or
supplement thereto. In no event shall the liability of an Investor be greater in
amount than the dollar amount of the proceeds (net of all expense paid by such
Investor and the amount of any damages such holder has otherwise been required
to pay by reason of such untrue statement or omission) received by such Investor
upon the sale of the Registrable Securities or Additional Registrable Securities
included in the Registration Statement giving rise to such indemnification
obligation.

                    (c) CONDUCT OF INDEMNIFICATION PROCEEDINGS. Any person
entitled to indemnification hereunder shall (i) give prompt notice to the
indemnifying party of any claim with respect to which it seeks indemnification
and (ii) permit such indemnifying party to assume the defense of such claim with
counsel reasonably satisfactory to the indemnified party; PROVIDED that any
person entitled to indemnification hereunder shall have the right to employ
separate counsel and to participate in the defense of such claim, but the fees
and expenses of such counsel shall be at the expense of such person unless (a)
the indemnifying party has agreed to pay such fees or expenses, or (b) the
indemnifying party shall have failed to assume the defense of such claim and
employ counsel reasonably satisfactory to such person or (c) in the reasonable
judgment of any such person, based upon written advice of its counsel, a
conflict of interest exists between such person and the indemnifying party with
respect to such claims (in which case, if the person notifies the indemnifying
party in writing that such person elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such claim on behalf of such person); and
PROVIDED, FURTHER, that the failure of any indemnified party to give notice as
provided herein shall not relieve the indemnifying party of its obligations
hereunder, except to the extent that such failure to give notice shall
materially adversely affect the indemnifying party in the defense of any such
claim or litigation. It is understood that the indemnifying party shall not, in
connection with any proceeding in the same jurisdiction, be liable for fees or
expenses of more than one separate firm of attorneys at any time for all such
indemnified parties. No indemnifying party will, except with the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability
in respect of such claim or litigation.

                    (d) CONTRIBUTION. If for any reason the indemnification
provided for in the preceding paragraphs (a) and (b) is unavailable to an
indemnified party or insufficient to hold it harmless, other than as expressly
specified therein, then the indemnifying party shall contribute to the amount
paid or payable by the indemnified party as a result of such loss, claim, damage
or liability in such proportion as is appropriate to reflect the relative fault
of the indemnified party and the indemnifying party, as well as any other
relevant equitable considerations. No person guilty of fraudulent
misrepresentation within the meaning of Section 11(f) of the 1933 Act shall be
entitled to contribution from any person not guilty of such fraudulent
misrepresentation. In no event shall the contribution obligation of a holder of
Registrable Securities or Additional Registrable Securities be greater in amount
than the dollar amount of the proceeds (net of all expenses paid by such holder
and the amount of any damages such holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission) received by it upon the sale of the Registrable Securities or
Additional Registrable Securities giving rise to such contribution obligation.

          7.   MISCELLANEOUS.

                    (a) AMENDMENTS AND WAIVERS. This Agreement may be amended
