clearing the Registrable Securities for sale under applicable state securities
laws, listing fees, but excluding discounts, commissions, fees of underwriters,
selling brokers, dealer managers or similar securities industry professionals
fees and other expenses (including fees and disbursements of counsel to the
Investors) incurred by the Investors in connection with the registration with
respect to the Registrable Securities being sold.

                        (c)     EFFECTIVENESS.

                        (i)     The Company shall use its best efforts to have
the Registration Statement declared effective as soon as practicable. The
Company shall notify the Investors by facsimile or e-mail as promptly as
practicable, and in any event, within twenty-four (24) hours, after any
Registration Statement is declared effective and shall simultaneously provide
the Investors with copies of any related Prospectus to be used in connection
with the sale or other disposition of the securities covered thereby. If a
Registration Statement covering the Registrable Securities is not declared
effective by the SEC prior to July 31, 2006, then the Company will make pro rata
payments to each Investor, as liquidated damages and not as a penalty, in an
amount equal to 1.0% of the portion of Purchase Price (as defined in the
Purchase Agreement) paid by each Investor pursuant to the Purchase Agreement,
for each 30-day period or pro rata for any portion thereof following the date by
which such Registration Statement should have been effective (the "Blackout
Period"); provided, however, that in no event shall the Company be liable for
liquidated damages in excess of 10% of the Purchase Price. Such payments shall
constitute the Investors' exclusive monetary remedy for such events, but shall
not affect the right of the Investors to seek injunctive relief. The amounts
payable as liquidated damages pursuant to this paragraph shall be paid monthly
within three (3) Business Days of the last day of each month following the
commencement of the Blackout Period until the termination of the Blackout
Period. Such payments shall be made to each Investor in cash.

                        (ii)    For not more than twenty (20) consecutive days
or for a total of not more than forty-five (45) days in any twelve (12) month
period, the Company may delay the disclosure of material non-public information
concerning the Company, by suspending the use of any Prospectus included in 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,
however, that the Company may suspend the use of any Prospectus included in any
registration contemplated by this Section, and such suspension shall not be
included in the number of days constituting an Allowed Delay, for a period
commencing on the date that the Company publicly announces its quarterly or
annual earnings and ending on the date that the SEC declares effective a
post-effective amendment to the related Registration Statement including updated
financial statements reflecting such earnings (an "Update Delay). Upon the
occurrence of an Allowed Delay or an

                                      -3-
<PAGE>

Update Delay that the Company shall promptly (a) notify the Investors in writing
of the existence of an Allowed Delay or an Update Delay (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, (b) advise the Investors in writing
to cease all sales under the Registration Statement until the end of the Allowed
Delay or Update Delay and (c) use commercially reasonable efforts to terminate
an Allowed Delay or Update Delay as promptly as practicable.

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

                        (a)     use commercially reasonable efforts to cause
such Registration Statement to become effective and to remain continuously

which all Registrable Securities covered by such Registration Statement as
amended from time to time, have been sold, and (ii) the date on which all
Registrable Securities covered by such Registration Statement may be sold
pursuant to Rule 144(k) (assuming that all of the Warrants are exercisable on a
cashless basis) (the "Effectiveness Period") and advise the Investors in writing
when the Effectiveness Period has expired;

                        (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
Effectiveness Period and to comply with the provisions of the 1933 Act and the
1934 Act with respect to the distribution of all of the Registrable Securities
covered thereby;

                        (c)     provide copies to and permit counsel designated
by the Investors to review each Registration Statement and all amendments and
supplements thereto no fewer than three (3) Business 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
SEC, or received by the Company (but not later than two (2) Business Days after
the filing date, receipt date or sending date, as the case may be) one (1) copy
of any Registration Statement and any amendment thereto, each preliminary
prospectus and Prospectus and each amendment or supplement thereto, 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 owned by such Investor that are covered by the related Registration
Statement;

                        (e)     use commercially reasonable efforts to (i)
prevent the issuance of any stop order or other suspension of effectiveness and,
(ii) if such order is issued, obtain the withdrawal of any such order at the
earliest possible moment;

                        (f)     prior to any public offering of Registrable
Securities, use commercially reasonable efforts to register or qualify or
cooperate with the Investors and their

                                      -4-
<PAGE>

counsel in connection with the registration or qualification of such Registrable
Securities for offer and sale under the securities or blue sky laws of such
jurisdictions requested by the Investors and do any and all other commercially
reasonable acts or things necessary or advisable to enable the distribution in
such jurisdictions of the Registrable Securities covered by the Registration
Statement; provided, however, that the Company shall not be required in
connection therewith or as a condition thereto to (i) qualify to do business in
any jurisdiction where it would not otherwise be required to qualify but for
this Section 3(f), (ii) subject itself to general taxation in any jurisdiction
where it would not otherwise be so subject but for this Section 3(f), or (iii)
file a general consent to service of process in any such jurisdiction;

                        (g)     use commercially reasonable efforts to cause all
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;

                        (h)     immediately notify the Investors, at any time
prior to the end of the Effectiveness Period, upon discovery that, or upon the
happening of any event as a result of which, the Prospectus 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
light of the circumstances then existing, and promptly prepare, file with the
SEC and furnish to such holder a supplement to or an amendment of such
Prospectus as may be necessary so that 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
light of the circumstances then existing; and

                        (i)     otherwise use commercially reasonable efforts to
comply with all applicable rules and regulations of the SEC under the 1933 Act
and the 1934 Act, including, without limitation, Rule 172 under the 1933 Act,
file any final Prospectus, including any supplement or amendment thereof, with
the SEC pursuant to Rule 424 under the 1933 Act, promptly inform the Investors
in writing if, at any time during the Effectiveness Period, the Company does not
satisfy the conditions specified in Rule 172 and, as a result thereof, the
Investors are required to deliver a Prospectus in connection with any
disposition of Registrable Securities and take such other actions as may be
reasonably necessary to facilitate the registration of the Registrable
Securities hereunder; and make available to its security holders, as soon as
reasonably practicable, but not later than the Availability Date (as defined
below), an earnings statement covering a period of at least twelve (12) 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, including Rule 158 promulgated thereunder (for the purpose of this
subsection 3(i), "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).

                        (j)     With a view to making available to the Investors
the benefits of Rule 144 (or its successor rule) and any other rule or
regulation of the SEC that may at any time permit the Investors to sell shares
of Common Stock to the public without registration, the Company covenants and
agrees to: (i) make and keep public information available, as those

                                      -5-
<PAGE>

terms are understood and defined in Rule 144, until the earlier of (A) six
months after such date as all of the Registrable Securities may be resold
pursuant to Rule 144(k) or any other rule of similar effect or (B) such date as
all of the Registrable Securities shall have been resold; (ii) file with the SEC
in a timely manner all reports and other documents required of the Company under
the 1934 Act; and (iii) furnish to each Investor upon request, as long as such
Investor owns any Registrable Securities, (A) a written statement by the Company
that it has complied with the reporting requirements of the 1934 Act, (B) a copy
of the Company's most recent Annual Report on Form 10-KSB or Quarterly Report on

order to avail such Investor of any rule or regulation of the SEC that permits
the selling of any such Registrable Securities without registration.

        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), all financial and other records, all SEC Filings (as defined in the
Purchase Agreement) 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, promptly, 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 such 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 and any Investor wishing to
obtain such information enters into an appropriate confidentiality agreement
with the Company with respect thereto.

        5.      OBLIGATIONS OF THE INVESTORS.
                        (a)     Each Investor shall furnish in writing to the

Company such information regarding itself, the Registrable Securities held by it
and the intended method of disposition of the Registrable Securities held by it,
including, without limitation, a completed Selling Stockholder Questionnaire in
the form attached hereto as EXHIBIT B, as shall be reasonably required to effect
the registration of such Registrable Securities and shall execute such documents
in connection with such registration as the Company may reasonably request. At
least five (5) 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 included in the Registration Statement.
An Investor shall provide such information to the Company at least three (3)
Business Days prior to the first anticipated filing date of such Registration
Statement if

                                      -6-
<PAGE>

such Investor elects to have any of the Registrable Securities included in the
Registration Statement. The Company shall not have any obligation hereunder with
respect to Registrable Securities held by an Investor that does not comply with
the terms and conditions of this Agreement.

                        (b)     Each Investor, by its acceptance of the
Registrable Securities 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 from
such Registration Statement.

                        (c)     Each Investor agrees that, upon receipt of any
notice from the Company of either (i) the commencement of an Allowed Delay or an
Update Delay pursuant to Section 2(c)(ii) or (ii) the happening of an event
pursuant to Section 3(h) hereof, such Investor will immediately discontinue
disposition of Registrable Securities pursuant to the Registration Statement
covering such Registrable Securities, until the Investor is advised by the
Company that such dispositions may again be made.

        6.      INDEMNIFICATION.

                        (a)     INDEMNIFICATION BY THE COMPANY. The Company will
indemnify and hold harmless each Investor and its officers, directors, members,
employees and agents, successors and assigns, and each other person, if any, who
controls such Investor within the meaning of the 1933 Act, against any losses,
claims, damages or liabilities, joint or several, to which they may become
subject under the 1933 Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon:
(i) any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, any preliminary Prospectus or final
Prospectus, or any amendment or supplement thereof; (ii) any blue sky
application or other document executed by the Company specifically for that
purpose or based upon written information furnished by the Company filed in any
state or other jurisdiction in order to qualify any or all of the Registrable
Securities under the securities laws thereof (any such application, document or
information herein called a "Blue Sky Application"); (iii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading; (iv) any violation
by the Company or its agents of any rule or regulation promulgated under the
1933 Act applicable to the Company or its agents and relating to action or
inaction required of the Company in connection with such registration; or (v)
any failure to register or qualify the Registrable Securities included in any
such Registration in any state where the Company or its agents has affirmatively
undertaken or agreed in writing that the Company will undertake such
registration or qualification on an Investor's behalf and will reimburse such
Investor, and each such officer, director or member and each such controlling
person for any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability or
action; PROVIDED, HOWEVER, that the Company will not be liable in any such case
if and to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission so made in conformity with information furnished by such
Investor or any such controlling person in writing specifically for use in such
Registration Statement or Prospectus.

                                      -7-
<PAGE>

                        (b)     INDEMNIFICATION BY THE INVESTORS. Each Investor
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 fees) resulting from (i) any breach of
the terms hereof by such Investor, (ii) any violation by such Investor or its
agents of any rule or regulation promulgated under the 1933 Act applicable to
the Investor or its agents and relating to the sale or other disposition of such
Investor's Registrable Securities, or (iii) 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. 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 in connection with any claim relating to this
Section 6 and the amount of any damages such Investor 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 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

                                      -8-
<PAGE>

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 be greater in amount than the
dollar amount of the proceeds (net of all expenses paid by such holder in
connection with any claim relating to this Section 6 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 giving rise to such contribution
obligation.

        7.      MISCELLANEOUS.

                        (a)     AMENDMENTS AND WAIVERS. This Agreement may be
amended only by a writing signed by the Company and the Required Investors. The
Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, only if the Company shall have obtained the
written consent to such amendment, action or omission to act, of the Required
Investors.

                        (b)     NOTICES. All notices and other communications
provided for or permitted hereunder shall be made as set forth in Section 9.4 of
the Purchase Agreement.

                        (c)     ASSIGNMENTS AND TRANSFERS BY INVESTORS. The
provisions of this Agreement shall be binding upon and inure to the benefit of
the Investors and their respective successors and assigns. An Investor may
transfer or assign, in whole or from time to time in part, to one or more
persons its rights hereunder in connection with the transfer of Registrable
Securities by such Investor to such person, provided that such Investor complies

                                                                       EXHIBIT A

                              PLAN OF DISTRIBUTION

        The selling stockholders, which as used herein includes donees,
pledgees, transferees or other successors-in-interest selling shares of common
stock or interests in shares of common stock received after the date of this
prospectus from a selling stockholder as a gift, pledge, partnership
distribution or other transfer, may, from time to time, sell, transfer or
otherwise dispose of any or all of their shares of common stock or interests in
shares of common stock on any stock exchange, market or trading facility on
which the shares are traded or in private transactions. These dispositions may
be at fixed prices, at prevailing market prices at the time of sale, at prices
related to the prevailing market price, at varying prices determined at the time
of sale, or at negotiated prices.

        The selling stockholders may use any one or more of the following
methods when disposing of shares or interests therein:

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

        - 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;

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

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

        - privately negotiated transactions;

        - short sales effected after the date the registration statement of
which this Prospectus is a part is declared effective by the SEC;

        - through the writing or settlement of options or other hedging
transactions, whether through an options exchange or otherwise;

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

        - a combination of any such methods of sale.

        The selling stockholders may, from time to time, pledge or grant a
security interest in some or all of the shares of common stock owned by them
and, if they default in the performance of their secured obligations, the
pledgees or secured parties may offer and sell the shares of common stock, from
time to time, under this prospectus, or under an amendment to this prospectus
under Rule 424(b)(3) or other applicable provision of the Securities Act
amending the list of selling stockholders to include the pledgee, transferee or
other successors in interest as

                                      -23-
<PAGE>

selling stockholders under this prospectus. The selling stockholders also may
transfer the shares of common stock in other circumstances, in which case the
transferees, pledgees or other successors in interest will be the selling
beneficial owners for purposes of this prospectus.

        In connection with the sale of our common stock or interests therein,
the selling stockholders may enter into hedging transactions with broker-dealers
or other financial institutions, which may in turn engage in short sales of the
common stock in the course of hedging the positions they assume. The selling
stockholders may also sell shares of our common stock short and deliver these
securities to close out their short positions, or loan or pledge the common
stock to broker-dealers that in turn may sell these securities. The selling
stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions or the creation of one or more
derivative securities which require the delivery to such broker-dealer or other
financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

        The aggregate proceeds to the selling stockholders from the sale of the
common stock offered by them will be the purchase price of the common stock less
discounts or commissions, if any. Each of the selling stockholders reserves the
right to accept and, together with their agents from time to time, to reject, in
whole or in part, any proposed purchase of common stock to be made directly or
through agents. We will not receive any of the proceeds from this offering. Upon
any exercise of the warrants by payment of cash, however, we will receive the
exercise price of the warrants.

        The selling stockholders also may resell all or a portion of the shares
in open market transactions in reliance upon Rule 144 under the Securities Act
of 1933, provided that they meet the criteria and conform to the requirements of
that rule.

        The selling stockholders and any underwriters, broker-dealers or agents
that participate in the sale of the common stock or interests therein may be
"underwriters" within the meaning of Section 2(11) of the Securities Act. Any
discounts, commissions, concessions or profit they earn on any resale of the
shares may be underwriting discounts and commissions under the Securities Act.
Selling stockholders who are "underwriters" within the meaning of Section 2(11)
of the Securities Act will be subject to the prospectus delivery requirements of
the Securities Act.

        To the extent required, the shares of our common stock to be sold, the
names of the selling stockholders, the respective purchase prices and public
offering prices, the names of any agents, dealer or underwriter, any applicable
commissions or discounts with respect to a particular offer will be set forth in
an accompanying prospectus supplement or, if appropriate, a post-effective
amendment to the registration statement that includes this prospectus.

        In order to comply with the securities laws of some states, if
applicable, the common stock may be sold in these jurisdictions only through
registered or licensed brokers or dealers. In addition, in some states the
common stock may not be sold unless it has been registered or qualified for sale
or an exemption from registration or qualification requirements is available and
is complied with.

                                      -24-

        We have advised the selling stockholders that the anti-manipulation
rules of Regulation M under the Exchange Act may apply to sales of shares in the
market and to the activities of the selling stockholders and their affiliates.
In addition, to the extent applicable we will make copies of this prospectus (as
it may be supplemented or amended from time to time) available to the selling
stockholders for the purpose of satisfying the prospectus delivery requirements
of the Securities Act. The selling stockholders may indemnify any broker-dealer
that participates in transactions involving the sale of the shares against
certain liabilities, including liabilities arising under the Securities Act.

        We have agreed to indemnify the selling stockholders against
liabilities, including liabilities under the Securities Act and state securities
laws, relating to the registration of the shares offered by this prospectus.

        We have agreed with the selling stockholders to keep the registration
statement of which this prospectus constitutes a part effective until the
earlier of (1) such time as all of the shares covered by this prospectus have
been disposed of pursuant to and in accordance with the registration statement
or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the
Securities Act.
