receipt and sufficiency of which are hereby acknowledged, the Company and each
of the Investors hereby amend and restate the Prior Agreement to read in its
entirety as follows:

                  1. DEFINITIONS.

shall have the following meanings:

                                    (i) "INVESTORS" has the meaning set forth in

assignee who agrees to become bound by the provisions of this Agreement in
accordance with Section 9 hereof.

                                    (ii) "REGISTER," "REGISTERED," and

pursuant to Rule 415 under the 1933 Act or any successor rule providing for

ordering of effectiveness of such Registration Statement by the United States
Securities and Exchange Commission (the "SEC").


                                       1
<PAGE>

                                    (iii) "REGISTRABLE SECURITIES" means (i) the
Conversion Shares issued or issuable upon conversion or otherwise pursuant to
the Debentures, (ii) the Warrant Shares issuable, upon exercise or otherwise
pursuant to the Warrants, (iii) any shares of Common Stock which were
"Registrable Securities" as defined in the Prior Agreement, (iv) shares and
shares of common stock issued or issuable upon conversion of warrants issued by
the Company to Alpha Capital Aktiengesellschaft pursuant to that certain
Subscription Agreement, dated December 30, 2004, and (v) any shares of capital
stock issued or issuable as a dividend on or in exchange for or otherwise with
respect to any of the foregoing.

                                    (iv) "REGISTRATION STATEMENT" means a
registration statement of the Company under the 1933 Act.

                           b. Capitalized terms used herein and not otherwise
defined herein shall have the respective meanings set forth in the New Purchase
Agreement, the Debentures, or the Warrants.

                  2. REGISTRATION.

                           a. MANDATORY REGISTRATION. Pursuant to the Prior
Agreement, the Company has filed with the SEC a Registration Statement on Form
SB-2, SEC File no. 333-120449, covering the resale of certain securities issued
pursuant to the Prior Purchase Agreement. The Company shall prepare, and, on or
prior to January 31, 2005 (the "AMENDMENT FILING DATE"), file a pre-effective
amendment to such Registration Statement so that the Registration Statement (as
amended) shall cover the resale of all of the Registrable Securities, which
Registration Statement, to the extent allowable under the 1933 Act and the rules
and regulations promulgated thereunder (including Rule 416), shall state that
such Registration Statement also covers such indeterminate number of additional
shares of Common Stock as may become issuable upon conversion of or otherwise
pursuant to the Debentures and Warrants to prevent dilution resulting from stock
splits, stock dividends or similar transactions. The Company acknowledges that
the number of shares to be included in the Registration Statement (as amended)
represents a good faith estimate of the maximum number of shares issuable upon
conversion of the Debentures and upon exercise of the Warrants.

                           b. UNDERWRITTEN OFFERING. If any offering pursuant to
a Registration Statement pursuant to Section 2(a) hereof involves an
underwritten offering, (i) the Investors who hold a majority in interest of the
Registrable Securities subject to such underwritten offering shall have the
right to select one legal counsel and an investment banker or bankers and
manager or managers to administer the offering, which investment banker or
bankers or manager or managers shall be reasonably satisfactory to the Company,
and (ii) the Original Investors who hold a majority in interest of the
Registrable Securities among the Original Investors subject to such underwritten
offering shall have the right to select one legal counsel.

                           c. PAYMENTS BY THE COMPANY. The Company shall use its
best efforts to obtain effectiveness of the Registration Statement as soon as
practicable. If (i) the pre-effective amendment to the Registration Statement
covering the Registrable Securities required to be filed by the Company pursuant
to Section 2(a) hereof is not filed by the Amendment Filing Date or the
Registration Statement (as amended) is not declared effective by the SEC on or
prior to one hundred thirty-five (135) days from the date of this Agreement, or
(ii) after the Registration Statement has been declared effective by the SEC,
sales of all of the Registrable Securities cannot be made pursuant to the
Registration Statement, or (iii) the Common Stock is not listed or included for
quotation on the Nasdaq National Market ("NASDAQ"), the Nasdaq SmallCap Market


                                       2
<PAGE>

("NASDAQ SMALLCAP"), the New York Stock Exchange (the "NYSE") or the American
Stock Exchange (the "AMEX") after being so listed or included for quotation, or
(iv) the Common Stock ceases to be traded on the Over-the-Counter Bulletin Board
(the "OTCBB") or any equivalent replacement exchange prior to being listed or
included for quotation on one of the aforementioned markets, then the Company
will make payments to the Investors in such amounts and at such times as shall
be determined pursuant to this Section 2(c) as partial relief for the damages to
the Investors by reason of any such delay in or reduction of their ability to
sell the Registrable Securities (which remedy shall not be exclusive of any
other remedies available at law or in equity). The Company shall pay to each
holder of the Debentures or Registrable Securities an amount equal to the
original principal amount of Debentures ("ORIGINAL PRINCIPAL Amount"),
multiplied by the Applicable Percentage (as defined below) times the sum of: (i)
the number of months (prorated for partial months) after the Amendment Filing
Date or the end of the aforementioned ninety (90) day period and prior to the
date the Registration Statement is declared effective by the SEC, provided,
however, that there shall be excluded from such period any delays which are
solely attributable to changes required by the Investors in the Registration
Statement with respect to information relating to the Investors, including,
without limitation, changes to the plan of distribution, or to the failure of
the Investors to conduct their review of the Registration Statement pursuant to
Section 3(h) below in a reasonably prompt manner; (ii) the number of months
(prorated for partial months) that sales of all of the Registrable Securities
cannot be made pursuant to the Registration Statement after the Registration
Statement has been declared effective (including, without limitation, when sales
cannot be made by reason of the Company's failure to properly supplement or
amend the prospectus included therein in accordance with the terms of this
Agreement, but excluding any days during an Allowed Delay (as defined in Section
3(f)); and (iii) the number of months (prorated for partial months) that the
Common Stock is not listed or included for quotation on the OTCBB, Nasdaq,
Nasdaq SmallCap, NYSE or AMEX or that trading thereon is halted after the
Registration Statement has been declared effective. The term "APPLICABLE
PERCENTAGE" means three percent (3%).

                           d. PIGGY-BACK REGISTRATIONS. Subject to the last
sentence of this Section 2(d), if at any time prior to the expiration of the
Registration Period (as hereinafter defined) the Company shall determine to file
with the SEC a Registration Statement relating to an offering for its own
account or the account of others under the 1933 Act of any of its equity
securities (other than on Form S-4 or Form S-8 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 BONA FIDE, employee benefit plans), the
Company shall send to each Investor who is entitled to registration rights under
this Agreement written notice of such determination and, if within fifteen (15)
days after the effective date of such notice, such Investor shall so request in
writing, the Company shall include in such Registration Statement all or any
part of the Registrable Securities such Investor requests to be registered,
except that if, in connection with any underwritten public offering for the
account of the Company the managing underwriter(s) thereof shall impose a
limitation on the number of shares of Common Stock which may be included in the
Registration Statement because, in such underwriter(s)' judgment, marketing or
other factors dictate such limitation is necessary to facilitate public
distribution, then the Company shall be obligated to include in such
Registration Statement only such limited portion of the Registrable Securities
with respect to which such Investor has requested inclusion hereunder as the
underwriter shall permit. Any exclusion of Registrable Securities shall be made
pro rata among the Investors seeking to include Registrable Securities in
proportion to the number of Registrable Securities sought to be included by such
Investors; PROVIDED, HOWEVER, that the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding securities, the
holders of which are not entitled to inclusion of such securities in such
Registration Statement or are not entitled to pro rata inclusion with the
Registrable Securities; and PROVIDED, FURTHER, HOWEVER, that, after giving
effect to the immediately preceding proviso, any exclusion of Registrable
Securities shall be made pro rata with holders of other securities having the
right to include such securities in the Registration Statement other than
holders of securities entitled to inclusion of their securities in such


                                       3
<PAGE>

Registration Statement by reason of demand registration rights. No right to
registration of Registrable Securities under this Section 2(d) shall be
construed to limit any registration required under Section 2(a) hereof. If an
offering in connection with which an Investor is entitled to registration under
this Section 2(d) is an underwritten offering, then each Investor whose
Registrable Securities are included in such Registration Statement shall, unless
otherwise agreed by the Company, offer and sell such Registrable Securities in
an underwritten offering using the same underwriter or underwriters and, subject
to the provisions of this Agreement, on the same terms and conditions as other
shares of Common Stock included in such underwritten offering. Notwithstanding
anything to the contrary set forth herein, the registration rights of the
Investors pursuant to this Section 2(d) shall only be available in the event the
Company fails to timely file, obtain effectiveness or maintain effectiveness of
any Registration Statement to be filed pursuant to Section 2(a) in accordance
with the terms of this Agreement.

                           e. ELIGIBILITY FOR FORM S-3, SB-2 OR S-1; CONVERSION
TO FORM S-3. The Company represents and warrants that it meets the requirements
for the use of Form S-3, SB-2 or S-1 for registration of the sale by the
Investors of the Registrable Securities. The Company agrees to file all reports
required to be filed by the Company with the SEC in a timely manner so as to
remain eligible or become eligible, as the case may be, and thereafter to
maintain its eligibility, for the use of Form S-3. If the Company is not
currently eligible to use Form S-3, not later than five (5) business days after
the Company first meets the registration eligibility and transaction
requirements for the use of Form S-3 (or any successor form) for registration of
the offer and sale by the Investors of Registrable Securities, the Company shall
file a Registration Statement on Form S-3 (or such successor form) with respect
to the Registrable Securities covered by the Registration Statement on Form SB-2
or Form S-1, whichever is applicable, filed pursuant to Section 2(a) (and
include in such Registration Statement on Form S-3 the information required by
Rule 429 under the 1933 Act) or convert the Registration Statement on Form SB-2
or Form S-1, whichever is applicable, filed pursuant to Section 2(a) to a Form
S-3 pursuant to Rule 429 under the 1933 Act and cause such Registration
Statement (or such amendment) to be declared effective no later than forty-five
(45) days after filing. In the event of a breach by the Company of the
provisions of this Section 2(e), the Company will be required to make payments
pursuant to Section 2(c) hereof.

                  3. OBLIGATIONS OF THE COMPANY.

         In connection with the registration of the Registrable Securities, the
Company shall have the following obligations:

                           a. The Company shall prepare promptly, and file with
the SEC not later than the Amendment Filing Date, a pre-effective amendment to
the Registration Statement so that the Registration Statement (as amended)
covers all of the Registrable Securities, as provided in Section 2(a), and
thereafter use its best efforts to cause such Registration Statement relating to
Registrable Securities to become effective as soon as possible after such filing
but in no event later than ninety (90) days from the date of this Agreement, and
keep the Registration Statement effective pursuant to Rule 415 at all times
until such date as is the earlier of (i) the date on which all of the
Registrable Securities have been sold and (ii) the date on which the Registrable
Securities (in the opinion of counsel to the Investors) may be immediately sold
to the public without registration or restriction (including, without
limitation, as to volume by each holder thereof) under the 1933 Act (the
"REGISTRATION Period"), which Registration Statement (including any amendments
or supplements thereto and prospectuses contained therein) shall not contain any
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.

                           b. The Company shall prepare and file with the SEC
such amendments (including post-effective amendments) and supplements to the
Registration Statements and the prospectus used in connection with the


                                       4
<PAGE>

Registration Statements as may be necessary to keep the Registration Statements
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act with respect to the disposition of
all Registrable Securities of the Company covered by the Registration Statements
until such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in the Registration Statements. In the event the number of
shares available under a Registration Statement filed pursuant to this Agreement
is insufficient to cover all of the Registrable Securities, the Company shall
amend the Registration Statement, or file a new Registration Statement (on the
short form available therefor, if applicable), or both, so as to cover all of
the Registrable Securities, in each case, as soon as practicable, but in any
event within fifteen (15) days after the necessity therefor arises (based on the
market price of the Common Stock and other relevant factors on which the Company
reasonably elects to rely). The Company shall use its best efforts to cause such
amendment and/or new Registration Statement to become effective as soon as
practicable following the filing thereof, but in any event within thirty (30)
days after the date on which the Company reasonably first determines (or
reasonably should have determined) the need therefor. The provisions of Section
2(c) above shall be applicable with respect to such obligation, with the ninety
(90) days running from the day the Company reasonably first determines (or
reasonably should have determined) the need therefor.

                           c. The Company shall furnish to each Investor whose
Registrable Securities are included in a Registration Statement and its legal
counsel (i) promptly (but in no event more than two (2) business days) after the
same is prepared and publicly distributed, filed with the SEC, or received by
the Company, one copy of each Registration Statement and any amendment thereto,
each preliminary prospectus and prospectus and each amendment or supplement
thereto, and, in the case of the Registration Statement referred to in Section
2(a), 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) promptly (but in no event more than two
(2) business days) after the Registration Statement is declared effective by the
SEC, such number of copies of a prospectus, including a preliminary prospectus,
and all amendments and supplements thereto and such other documents as such
Investor may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such Investor. The Company will immediately
notify each Investor by facsimile of the effectiveness of each Registration
Statement or any post-effective amendment. The Company will promptly (but in no
event more than five (5) business days) respond to any and all comments received
from the SEC (which comments shall promptly be made available to the Investors
upon request), with a view towards causing each Registration Statement or any
amendment thereto to be declared effective by the SEC as soon as practicable,
shall promptly file an acceleration request as soon as practicable (but in no
event more than two (2) business days) following the resolution or clearance of
all SEC comments or, if applicable, following notification by the SEC that any
such Registration Statement or any amendment thereto will not be subject to
review and shall promptly file with the SEC a final prospectus as soon as
practicable (but in no event more than two (2) business days) following receipt
by the Company from the SEC of an order declaring the Registration Statement
effective. In the event of a breach by the Company of the provisions of this
Section 3(c), the Company will be required to make payments pursuant to Section
2(c) hereof.

                           d. The Company shall use reasonable efforts to (i)
register and qualify the Registrable Securities covered by the Registration
Statements under such other securities or "blue sky" laws of such jurisdictions
in the United States as the Investors who hold a majority in interest of the
Registrable Securities being offered reasonably request, (ii) prepare and file
in those jurisdictions such amendments (including post-effective amendments) and
supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and


                                       5
<PAGE>

qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; PROVIDED, HOWEVER, that
the Company shall not be required in connection therewith or as a condition
thereto to (a) qualify to do business in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(d), (b) subject itself
to general taxation in any such jurisdiction, (c) file a general consent to
service of process in any such jurisdiction, (d) provide any undertakings that
cause the Company undue expense or burden, or (e) make any change in its charter
or bylaws, which in each case the Board of Directors of the Company determines
to be contrary to the best interests of the Company and its shareholders.

                           e. In the event Investors who hold a
majority-in-interest of the Registrable Securities being offered in the offering
select underwriters for the offering, the Company shall 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 underwriters of such offering.

                           f. As promptly as practicable after becoming aware of
such event, the Company shall notify each Investor of the happening of any
event, of which the Company has knowledge, as a result of which the prospectus
included in any Registration Statement, as then in effect, includes an untrue
statement of a material fact or omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
use its best efforts promptly to prepare a supplement or amendment to any
Registration Statement to correct such untrue statement or omission, and deliver
such number of copies of such supplement or amendment to each Investor as such
Investor may reasonably request; provided that, for not more than ten (10)
consecutive trading days (or 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 (as well as prospectus or
Registration Statement updating) 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, further, that the Company shall promptly (i) 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 (ii) advise the Investors in writing to cease all
sales under such Registration Statement until the end of the Allowed Delay. Upon
expiration of the Allowed Delay, the Company shall again be bound by the first
sentence of this Section 3(f) with respect to the information giving rise
thereto.

                           g. The Company shall use its best efforts to prevent
the issuance of any stop order or other suspension of effectiveness of any
Registration Statement, and, if such an order is issued, to obtain the
withdrawal of such order at the earliest possible moment and to notify each
Investor who holds Registrable Securities being sold (or, in the event of an
underwritten offering, the managing underwriters) of the issuance of such order
and the resolution thereof.

                           h. The Company shall permit a single firm of counsel
designated by the Investors (the "PRIMARY INVESTOR COUNSEL") and one other
single firm of counsel designated by the Original Investors, to review such
Registration Statement and all amendments and supplements thereto (as well as
all requests for acceleration or effectiveness thereof) a reasonable period of
time prior to their filing with the SEC, and not file any document in a form to
which Primary Investor Counsel reasonably objects and will not request
acceleration of such Registration Statement without prior notice to Primary
Investor Counsel. The sections of such Registration Statement covering
information with respect to the Investors, the Investor's beneficial ownership
of securities of the Company or the Investors intended method of disposition of
Registrable Securities shall conform to the information provided to the Company
by each of the Investors.


                                       6
<PAGE>

                           i. The Company shall make generally available to its
security holders as soon as practicable, but not later than ninety (90) days
after the close of the period covered thereby, an earnings statement (in form
complying with the provisions of Rule 158 under the 1933 Act) covering a
twelve-month period beginning not later than the first day of the Company's
fiscal quarter next following the effective date of the Registration Statement.

                           j. At the request of any Investor, the Company shall
furnish, on the date that Registrable Securities are delivered to an
underwriter, if any, for sale in connection with any Registration Statement or,
if such securities are not being sold by an underwriter, on the date of
effectiveness thereof (i) an opinion, dated as of such date, from counsel
representing the Company for purposes of such Registration Statement, in form,
scope and substance as is customarily given in an underwritten public offering,
addressed to the underwriters, if any, and the Investors and (ii) a letter,
dated such 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
underwriters, if any, and the Investors.

                           k. The Company shall make available for inspection by
(i) any Investor, (ii) any underwriter participating in any disposition pursuant
to a Registration Statement, (iii) one firm of attorneys and one firm of
accountants or other agents retained by the Investors, (iv) one firm of
attorneys and one firm of accountants or other agents retained by all other
Investors, and (v) one firm of attorneys retained by all such underwriters
(collectively, the "INSPECTORS") all pertinent financial and other records, and
pertinent corporate documents and properties of the Company, including without
limitation, records of conversions by other holders of convertible securities
issued by the Company and the issuance of stock to such holders pursuant to the
conversions (collectively, the "RECORDS"), as shall be reasonably deemed
necessary by each Inspector to enable each Inspector to exercise its due
diligence responsibility, and cause the Company's officers, directors and
employees to supply all information which any Inspector may reasonably request
for purposes of such due diligence; PROVIDED, HOWEVER, that each Inspector shall
hold in confidence and shall not make any disclosure (except to an Investor) of
any Record or other information which the Company determines in good faith to be
confidential, and of which determination the Inspectors are so notified, unless
(a) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (b) the release of such
Records is ordered pursuant to a subpoena or other order from a court or
government body of competent jurisdiction, or (c) the information in such
Records has been made generally available to the public other than by disclosure
in violation of this or any other agreement. The Company shall not be required
to disclose any confidential information in such Records to any Inspector until
and unless such Inspector shall have entered into confidentiality agreements (in
form and substance satisfactory to the Company) with the Company with respect
thereto, substantially in the form of this Section 3(k). Each Investor agrees
that it shall, upon learning that disclosure of such Records is sought in or by
a court or governmental body of competent jurisdiction or through other means,
give prompt notice to the Company and allow the Company, at its expense, to
undertake appropriate action to prevent disclosure of, or to obtain a protective
order for, the Records deemed confidential. Nothing herein (or in any other
confidentiality agreement between the Company and any Investor) shall be deemed
to limit the Investor's ability to sell Registrable Securities in a manner which
is otherwise consistent with applicable laws and regulations.

                           l. The Company shall hold in confidence and not make
any disclosure of information concerning an Investor provided to the Company
unless (i) disclosure of such information is necessary to comply with federal or
state securities laws, (ii) the disclosure of such information is necessary to
avoid or correct a misstatement or omission in any Registration Statement, (iii)
the release of such information is ordered pursuant to a subpoena or other order
from a court or governmental body of competent jurisdiction, or (iv) such
information has been made generally available to the public other than by
disclosure in violation of this or any other agreement. The Company agrees that


                                       7
<PAGE>

it shall, upon learning that disclosure of such information concerning an
Investor is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to such Investor prior
to making such disclosure, and allow the Investor, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, such information.

                           m. The Company shall (i) cause all the Registrable
Securities covered by the Registration Statement to be listed on each national
securities exchange on which securities of the same class or series issued by
the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange, or (ii) to the
extent the securities of the same class or series are not then listed on a
national securities exchange, secure the designation and quotation, of all the
Registrable Securities covered by the Registration Statement on Nasdaq or, if
not eligible for Nasdaq, on Nasdaq SmallCap or, if not eligible for Nasdaq or
Nasdaq SmallCap, on the OTCBB and, without limiting the generality of the
foregoing, to arrange for at least two market makers to register with the
National Association of Securities Dealers, Inc. ("NASD") as such with respect
to such Registrable Securities.

                           n. The Company shall provide a transfer agent and
registrar, which may be a single entity, for the Registrable Securities not
later than the effective date of the Registration Statement.

                           o. The Company shall cooperate with the Investors who
hold Registrable Securities being offered and the managing underwriter or
underwriters, if any, to facilitate the timely preparation and delivery of
certificates (not bearing any restrictive legends) representing Registrable
Securities to be offered pursuant to a Registration Statement and enable such
certificates to be in such denominations or amounts, as the case may be, as the
managing underwriter or underwriters, if any, or the Investors may reasonably
request and registered in such names as the managing underwriter or
underwriters, if any, or the Investors may request.

                           p. At the request of the holders of a
majority-in-interest of the Registrable Securities, the Company shall prepare
and file with the SEC such amendments (including post-effective amendments) and
supplements to a Registration Statement and any prospectus used in connection
with the Registration Statement as may be necessary in order to change the plan
of distribution set forth in such Registration Statement.

                           q. Other than those security holders to be included
as selling security holders in the Registration Statement pursuant to
registration rights disclosed in the Company's Disclosure Schedule, from and
after the date of this Agreement, the Company shall not, and shall not agree to,
allow the holders of any securities of the Company to include any of their
securities in any Registration Statement under Section 2(a) hereof or any
amendment or supplement thereto under Section 3(b) hereof without the consent of
the holders of two-thirds of the Registrable Securities.

                           r. The Company shall take all other reasonable
actions necessary to expedite and facilitate disposition by the Investors of
Registrable Securities pursuant to a Registration Statement.

                  4. OBLIGATIONS OF THE INVESTORS.

         In connection with the registration of the Registrable Securities, the
Investors shall have the following obligations:

                           a. It shall be a condition precedent to the
obligations of the Company to complete the registration pursuant to this
Agreement with respect to the Registrable Securities of a particular Investor
that such Investor shall furnish to the Company such information regarding


                                       8
<PAGE>

itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it 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 three (3) business days prior to the first
anticipated filing date of the pre-effective amendment to the Registration
Statement (and any other amendments), the Company shall notify each Investor of
the information the Company requires from each such Investor.

                           b. Each Investor, by such Investor's 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 any
Registration Statements hereunder, unless such Investor has notified the Company
in writing of such Investor's election to exclude all of such Investor's
Registrable Securities from such Registration Statements.

                           c. In the event Investors holding a
majority-in-interest of the Registrable Securities being registered determine to
engage the services of an underwriter, each Investor agrees to enter into and
perform such Investor's 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 disposition of the Registrable Securities, unless such Investor
has notified the Company in writing of such Investor's election to exclude all
of such Investor's Registrable Securities from such Registration Statement.

                           d. Each Investor agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
Section 3(f) or 3(g), such Investor will immediately discontinue disposition of
Registrable Securities pursuant to the Registration Statement covering such
Registrable Securities until such Investor's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3(f) or 3(g) and, if
so directed by the Company, such 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 such Investor's possession, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice.

                           e. No Investor may participate in any underwritten
registration hereunder unless such Investor (i) agrees to sell such Investor's
Registrable Securities 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 Section 5 below.

                  5. EXPENSES OF REGISTRATION.

         All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualification fees, printers and accounting fees, the
fees and disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel selected by the Investors and one counsel selected
by the Original Investors pursuant to Sections 2(b) and 3(h) hereof shall be
borne by the Company.

                  6. INDEMNIFICATION.

         In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

                           a. To the extent permitted by law, the Company will
indemnify, hold harmless and defend (i) each Investor who holds such Registrable
Securities, (ii) the directors, officers, partners, employees, agents and each
person who controls any Investor within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 ACT"), if any, (iii) any
underwriter (as defined in the 1933 Act) for the Investors, and (iv) the
directors, officers, partners, employees and each person who controls any such
underwriter within the meaning of the 1933 Act or the 1934 Act, if any (each, an
"INDEMNIFIED PERSON"), against any joint or several losses, claims, damages,
liabilities or expenses (collectively, together with actions, proceedings or
inquiries by any regulatory or self-regulatory organization, whether commenced
or threatened, in respect thereof, "CLAIMS") to which any of them may become
subject insofar as such Claims arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact in a Registration
Statement or the omission or alleged omission to state therein a material fact
required to be stated or necessary to make the statements therein not
misleading; (ii) any untrue statement or alleged untrue statement of a material
fact contained in any preliminary prospectus if used prior to the effective date
of such Registration Statement, or contained in the final prospectus (as amended
or supplemented, if the Company files any amendment thereof or supplement
thereto with the SEC) or the omission or alleged omission to state therein any
material fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading; or
(iii) any violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any other law, including, without limitation, any state securities
law, or any rule or regulation thereunder relating to the offer or sale of the
Registrable Securities (the matters in the foregoing clauses (i) through (iii)
being, collectively, "Violations"). Subject to the restrictions set forth in
Section 6(c) with respect to the number of legal counsel, the Company shall
reimburse the Indemnified Person, promptly as such expenses are incurred and are
due and payable, for any reasonable legal fees or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(a): (i) shall not apply to a Claim arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Company by any Indemnified Person
or underwriter for such Indemnified Person expressly for use in connection with
the preparation of such Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) hereof; (ii) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld; and
(iii) with respect to any preliminary prospectus, shall not inure to the benefit
of any Indemnified Person if the untrue statement or omission of material fact
contained in the preliminary prospectus was corrected on a timely basis in the
prospectus, as then amended or supplemented, such corrected prospectus was
timely made available by the Company pursuant to Section 3(c) hereof, and the
Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a Violation and such Indemnified
Person, notwithstanding such advice, used it. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9.

                           b. In connection with any Registration Statement in
which an Investor is participating, each such Investor agrees severally and not
jointly to indemnify, hold harmless and defend, to the same extent and in the
same manner set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the Registration Statement, each person, if any, who
controls the Company within the meaning of the 1933 Act or the 1934 Act, any
underwriter and any other shareholder selling securities pursuant to the


                                       10
<PAGE>

Registration Statement or any of its directors or officers or any person who
controls such shareholder or underwriter within the meaning of the 1933 Act or
the 1934 Act (collectively and together with an Indemnified Person, an
"INDEMNIFIED PARTY"), against any Claim to which any of them may become subject,
under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim arises out
of or is based upon any Violation by such Investor, in each case to the extent
(and only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished to the Company by such Investor
expressly for use in connection with such Registration Statement; and subject to
Section 6(c) such Investor will reimburse any legal or other expenses (promptly
as such expenses are incurred and are due and payable) reasonably incurred by
them in connection with investigating or defending any such Claim; PROVIDED,
HOWEVER, that the indemnity agreement contained in this Section 6(b) shall not
apply to amounts paid in settlement of any Claim if such settlement is effected
without the prior written consent of such Investor, which consent shall not be
unreasonably withheld; PROVIDED, FURTHER, HOWEVER, that the Investor shall be
liable under this Agreement (including this Section 6(b) and Section 7) for only
that amount as does not exceed the net proceeds to such Investor as a result of
the sale of Registrable Securities pursuant to such Registration Statement. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Party and shall survive the transfer of
the Registrable Securities by the Investors pursuant to Section 9.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(b) with respect to any preliminary
prospectus shall not inure to the benefit of any Indemnified Party if the untrue
statement or omission of material fact contained in the preliminary prospectus
was corrected on a timely basis in the prospectus, as then amended or
supplemented.

                           c. Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action (including any governmental action), such Indemnified Person or
Indemnified Party shall, if a Claim in respect thereof is to be made against any
indemnifying party under this Section 6, deliver to the indemnifying party a
written notice of the commencement thereof, and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel mutually satisfactory to the
indemnifying party and the Indemnified Person or the Indemnified Party, as the
case may be; PROVIDED, HOWEVER, that an Indemnified Person or Indemnified Party
shall have the right to retain its own counsel with the fees and expenses to be
paid by the indemnifying party, if, in the reasonable opinion of counsel
retained by the indemnifying party, the representation by such counsel of the
Indemnified Person or Indemnified Party and the indemnifying party would be
inappropriate due to actual or potential differing interests between such
Indemnified Person or Indemnified Party and any other party represented by such
counsel in such proceeding. The indemnifying party shall pay for only one
separate legal counsel for the Indemnified Persons or the Indemnified Parties,
as applicable, and such legal counsel shall be selected by Investors holding a
majority-in-interest of the Registrable Securities included in the Registration
Statement to which the Claim relates, if the Investors are entitled to
indemnification hereunder, or the Company, if the Company is entitled to
indemnification hereunder, as applicable. The failure to deliver written notice
to the indemnifying party within a reasonable time of the commencement of any
such action shall not relieve such indemnifying party of any liability to the
Indemnified Person or Indemnified Party under this Section 6, except to the
extent that the indemnifying party is actually prejudiced in its ability to
defend such action. The indemnification required by this Section 6 shall be made
by periodic payments of the amount thereof during the course of the
investigation or defense, as such expense, loss, damage or liability is incurred
and is due and payable.


                                       11
<PAGE>

                  7. CONTRIBUTION.

         To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; PROVIDED, HOWEVER, that
(i) no contribution shall be made under circumstances where the maker would not
have been liable for indemnification under the fault standards set forth in
Section 6, (ii) no seller of Registrable Securities guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any seller of Registrable Securities who was not
guilty of such fraudulent misrepresentation, and (iii) contribution (together
with any indemnification or other obligations under this Agreement) by any
seller of Registrable Securities shall be limited in amount to the net amount of
proceeds received by such seller from the sale of such Registrable Securities.

                  8. REPORTS UNDER THE 1934 ACT.

         Whether, with a view to making available to the Investors the benefits
of Rule 144 promulgated under the 1933 Act or any other similar rule or
regulation of the SEC that may at any time permit the Investors to sell
securities of the Company to the public without registration ("RULE 144") or
otherwise, the Company agrees to:

                           a. make and keep public information available, as
those terms are understood and defined in Rule 144;

                           b. file with the SEC in a timely manner all reports
and other documents required of the Company under the 1933 Act and the 1934 Act
so long as the Company remains subject to such requirements and the filing of
such reports and other documents is required for the applicable provisions of
Rule 144; and

                           c. furnish to each Investor so long as such Investor
owns Registrable Securities, promptly upon request, (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144,
the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested to
permit the Investors to sell such securities pursuant to Rule 144 without
registration.

                  9. ASSIGNMENT OF REGISTRATION RIGHTS.

         The rights under this Agreement shall be automatically assignable by
the Investors to any transferee of all or any portion of Registrable Securities
if: (i) the Investor agrees in writing with the transferee or assignee to assign
such rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment, (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b) the securities with
respect to which such registration rights are being transferred or assigned,
(iii) following such transfer or assignment, the further disposition of such
securities by the transferee or assignee is restricted under the 1933 Act and
applicable state securities laws, (iv) at or before the time the Company
receives the written notice contemplated by clause (ii) of this sentence, the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein, (v) such transfer shall have been made in
accordance with the applicable requirements of the New Purchase Agreement, and
(vi) such transferee shall be an "accredited investor" as that term defined in
Rule 501 of Regulation D promulgated under the 1933 Act.

observance of any term of this Agreement may be waived (either generally or in a
particular instance and either retroactively or prospectively) only with the
written consent of the Company and the holders of 75% of the Registrable
Securities. Any termination, amendment or waiver effected in accordance with
this paragraph shall be binding upon each holder of the Registrable Securities,
each future holder of the Registrable Securities, their successors and assigns,
and the Company.

                  11. MISCELLANEOUS.

                           a. A person or entity is deemed to be a holder of
Registrable Securities whenever such person or entity owns of record such
Registrable Securities. If the Company receives conflicting instructions,
notices or elections from two or more persons or entities with respect to the
same Registrable Securities, the Company shall act upon the basis of
instructions, notice or election received from the registered owner of such
Registrable Securities.

                           b. Any notices required or permitted to be given

receipt requested) or delivered personally or by courier (including a recognized
overnight delivery service) or by facsimile and shall be effective five days

                           d. THIS AGREEMENT SHALL BE ENFORCED, GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS. THE PARTIES HERETO HEREBY SUBMIT TO THE

MAINTENANCE OF SUCH SUIT OR PROCEEDING. THE PARTIES FURTHER AGREE THAT SERVICE
OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN EVERY
RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR

                           e. In the event that any provision of this Agreement
is invalid or unenforceable under any applicable statute or rule of law, then
such provision shall be deemed inoperative to the extent that it may conflict
therewith and shall be deemed modified to conform to such statute or rule of
law. Any provision hereof which may prove invalid or unenforceable under any law
shall not affect the validity or enforceability of any other provision hereof.

                           f. This Agreement constitutes the entire agreement
among the parties hereto with respect to the subject matter hereof. There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein. This Agreement supersedes all prior agreements and
understandings among the parties hereto with respect to the subject matter
hereof, including the Prior Agreement.

                           g. Subject to the requirements of Section 9 hereof,
this Agreement shall be binding upon and inure to the benefit of the parties and
their successors and assigns.

                           h. The headings in this Agreement are for convenience
of reference only and shall not form part of, or affect the interpretation of,
this Agreement.

                           i. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original but all of which shall
constitute one and the same agreement and shall become effective when
counterparts have been signed by each party and delivered to the other party.
This Agreement, once executed by a party, may be delivered to the other party
hereto by facsimile transmission of a copy of this Agreement bearing the
signature of the party so delivering this Agreement.

                           j. Each party shall do and perform, or cause to be
done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other party may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

                           k. Except as otherwise provided herein, all consents
and other determinations to be made by the Investors pursuant to this Agreement
shall be made by Investors holding 75% of the Registrable Securities, determined
as if all of the Debentures and Warrants outstanding have been converted into or
exercised for Registrable Securities.

                           l. The Company acknowledges that a breach by it of
its obligations hereunder will cause irreparable harm to each Investor by
vitiating the intent and purpose of the transactions contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for breach of its
obligations under this Agreement will be inadequate and agrees, in the event of
a breach or threatened breach by the Company of any of the provisions under this


                                       14

Agreement, that each Investor shall be entitled, in addition to all other
available remedies in law or in equity, and in addition to the penalties
assessable herein, to an injunction or injunctions restraining, preventing or
curing any breach of this Agreement and to enforce specifically the terms and
provisions hereof, without the necessity of showing economic loss and without
any bond or other security being required.

                           m. The language used in this Agreement will be deemed
to be the language chosen by the parties to express their mutual intent, and no
rules of strict construction will be applied against any party.
