"Securities Act"), and applicable state securities laws with respect to the
Subscribed Shares;

        NOW, THEREFORE, in consideration of the premises and the mutual

business and affairs of the Company, or (b) any material engagement or activity
by the Company which would, in the good faith determination of the Board of
Directors of the Company, be adversely affected by disclosure in a Registration
Statement at such time, which determination shall be accompanied by a good faith
determination by the Board of Directors of the Company that the Registration
Statement would be materially misleading absent the inclusion of such
information.

        (iv) "Subscriber", has the meaning set forth in the preamble to this
Agreement.

        (v) "Register", "registered" and "registration" refer to a registration

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

        (vi) "Registrable Securities" means the shares of Common Stock issued on
conversion of or as dividends on the Subscribed Shares, the Periodic Amount

Company under the Securities Act.

        (b) Capitalized terms used herein and not otherwise defined herein shall

        2. REGISTRATION.

        (a) MANDATORY REGISTRATION. The Company shall prepare and file with the
SEC, no later than sixty (60) business days after the Subscription Date
("Required Filing Date") with respect to the Series F Convertible Preferred
Stock, a Registration Statement on Form S-1, (or such other form of Registration
Statement as the Company shall be eligible to utilize) ("Registration
Statement"), in either event registering the resale by the Subscriber of a
sufficient number of shares of Common Stock for the Subscribers to sell the
Registrable Securities, and in any event not less than two hundred percent
(200%) of Registrable Securities (the "Initial Registrable Securities") on the
Subscription Date. Such Registration Statement shall state that, in accordance
with the Securities Act, it also covers such indeterminate number of additional
shares of Subscribed Shares as may become issuable to prevent dilution resulting
from stock splits, or stock dividends. If at any time (i) the number of
Subscribed Shares and (ii) the number of shares of Common Stock issuable upon
exercise of the Warrants exceeds seventy-five (75%) percent of the aggregate
number of shares of Common Stock then registered, the Company shall, within ten
(10) business days (such event the,

                                        2
<PAGE>
"Additional Registration Date") file with the SEC an additional Registration
Statement on Form [____] or any other applicable registration statement, to
register two hundred (200%) percent of the Registrable Securities that exceed
the aggregate number of shares of Common Stock already registered.

        (b) DEFAULT BY THE COMPANY. If the Registration Statement covering the
Registrable Securities required to be filed by the Company pursuant to Section
2(a) hereof is not declared effective within ninety (90) days from the
Subscription Date ("Required Effective Date"), or ten (10) days after the
Additional Registration Date ("Additional Required Effective Date") or a
Registration Default as defined in Section 3(g) hereof occurs; or the
Registration Statement is suspended for more than ten (10) days as set forth in
Section 3(i) hereof, or the Common Stock is delisted from trading on the OTC
Bulletin Board or an automated securities exchange as defined in Rule 144 under
the Securities Act (collectively "Default Events"), then (i) the commitment to
purchase the Series F Convertible Preferred Stock contained in the Private
Equity Credit Agreement and in this Agreement (the "Commitment") shall terminate
and the Subscriber shall be entitled to the sums and the Warrants set forth in
Section 2.1(b) and 2.7of the Private Equity Credit Agreement and (ii)the Company
will make payments to Subscriber in terms of SECTION 2(c) below.

        The Company acknowledges the occurrence of one or more Default Events
shall cause the Subscriber to suffer damages in an amount that shall be
difficult to ascertain. Accordingly, the parties agree that it is appropriate to
include in the Private Equity Credit Agreement a provision for liquidated
damages. The parties acknowledge and agree that the liquidated damages provision
set forth in this section represents the parties' good faith effort to quantify
such damages and, as such, agree that the form and amount of such liquidated
damages are reasonable and will not constitute a penalty. The payment of
liquidated damages shall not relieve the Company from its obligations to
register the Common Stock and deliver the Common Stock pursuant to the terms of
this Agreement and the Subscribed Shares.

        (c) PAYMENTS BY THE COMPANY.

                      (i) If the Registration Statement covering the Registrable
Securities with respect to the Registrable Shares is not effective by the
relevant Required Effective Date or by the Additional Required Effective Date,
as the case may be, or if Subscriber is restricted from making sales of
Registrable Securities covered by a previously effective Registration Statement
at any time (the date such restriction commences, a "RESTRICTED SALE DATE")
after the Effective Date other than during a Suspension Period (as defined
below), then the Company will make payments to Subscriber in such amounts and at
such times as shall be determined pursuant to this SECTION 2(c);

                      (ii) The amount (each a "PERIODIC AMOUNT") to be paid by
the Company to Subscriber shall be determined as of each Computation Date (as
defined below) and the Periodic Amount shall be equal to the Periodic Amount
Percentage (as defined below) of the Purchase Price for all the Series F
Convertible Preferred Stock then held by the Investor for the period from the
date

                                        3
<PAGE>
following the relevant Required Effective Date, Additional Required Effective
Date or Restricted Sale Date, as the case may be, to the first relevant
Computation Date, and thereafter to each subsequent Computation Date. The
"PERIODIC AMOUNT PERCENTAGE" means (A) two percent (2%) of the Purchase Price
for the period from the date following the relevant Required Effective Date,
Additional Required Effective Date or Restricted Sale Date, as the case may be,
to the second relevant Computation Date, and (B) three percent (3%) of the
Purchase Price to each Computation Date thereafter (prorated on a daily basis if
such period is less than thirty (30) days). By way of illustration and not in
limitation of the foregoing, if the Registration Statement for the Registrable
Securities relating to the Common Stock and Warrants issued on the Initial
Closing Date is timely filed but is not declared effective until one hundred
sixty-five (165) days after the date of the Initial Closing, the Periodic Amount
will aggregate five and one-half percent (5 1/2%) of the Purchase Price (2% for
days 91-20, 2% for days 121-150, and 1 1/2% for days 151-165). The Registration
Statement will include shares of Common Stock to pay the periodic Amount due, if
any.

                      (iii) Each Periodic Amount will be payable by the Company,
at the option of the Subscriber, in cash or other immediately available funds,
shares of Common Stock which have been included in a Registration Statement on
Form S-1 or Subscribed Shares (the "Periodic Amount Shares"), to Subscriber at
the end of each Computation Period, without requiring demand therefor by
Subscriber;

                      (iv) The parties acknowledge that the damages which may be
incurred by Subscriber if the Registration Statement has not been declared
effective by a Required Effective Date, including if the right to sell
Registrable Securities under a previously effective Registration Statement is
suspended, may be difficult to ascertain. The parties agree that the Periodic
Amount represents a reasonable estimate on the part of the parties, as of the
date of this Agreement, of the amount of such damages;

                      (v) Notwithstanding the foregoing, the amounts payable by
the Company pursuant to this SECTION 2(c) shall not be payable to the extent any
delay in the effectiveness of the Registration Statement occurs because of an
act of, or a failure to act or to act timely by Subscriber or its counsel, or in
the event all of the Registrable Securities may be sold pursuant to Rule 144 or
another available exemption under the Securities Act; and

                      (vi) "COMPUTATION DATE" means (A) the date which is the
earlier of (1) thirty (30) days after the any relevant Required Effective Date
or a Restricted Sale Date, as the case may be, or (2) the date after the such
Required Effective Date or Restricted Sale Date on which the Registration
Statement is filed (with respect to payments due as contemplated by SECTION
2(c)(i) hereof) or is declared effective or has its restrictions removed (with
respect to payments due as contemplated by SECTION 2(c)(ii) hereof), as the case
may be, and (B) each date which is the earlier of (1) thirty (30) days after the
previous Computation Date or (2) the date after the previous Computation Date on
which the Registration Statement is filed (with respect to payments due as
contemplated by SECTION 2(c)(i) hereof) or is declared effective or has its
restrictions removed (with

                                        4
<PAGE>
respect to payments due as contemplated by SECTION 2(c)(ii) hereof), as the case
may be.

        3. OBLIGATION OF THE COMPANY. In connection with the registration of the
Registrable Securities, the Company shall do each of the following:

        (a) Prepare promptly, and file with the SEC within thirty (30) Business
Days of the Subscription Date, a Registration Statement with respect to not less
than the number of Registrable Securities provided in Section 2(a) above, and,
thereafter, use all diligent efforts to cause the Registration Statement
relating to the Registrable Securities to become effective the earlier of (a)
five (5) business days after notice (oral or written) from the Securities and
Exchange Commission that the Registration Statement may be declared effective,
or (b) ninety (90) days after the Subscription Date, or (c)twenty (20) days
after the Additional Registration Date, and keep the Registration Statement
current and effective at all times until the earliest of (i) the date that is
one year after the completion of the last Closing Date under the Purchase
Agreement, (ii) the date when the Subscriber may sell all Registrable Securities
under Rule 144 without volume limitations, or (iii) the date the Subscriber no
longer owns any of the Registrable Securities (collectively, 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, in the light of the
circumstances under which they were made, not misleading;

        (b) Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration Statement effective at all times during the
Registration Period, and, during the Registration Period, and to comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities of the Company covered by the Registration Statement
until the expiration of the Registration Period.

        (c) Permit a single firm of counsel designated by Subscriber to review
the Registration Statement and all amendments and supplements thereto a
reasonable period of time (but not less than three (3) Business Days prior to
their filing with the SEC and not file any document in a form to which such
counsel reasonably objects.

        (d) Notify Subscriber and Subscriber's legal counsel identified to the
Company (which, until further notice, shall be deemed to be Krieger & Prager,
LLP, ATTN: Samuel Krieger, Esq.; "SUBSCRIBER'S COUNSEL") (and, in the case of
(i)(A) below, not less than three (3) Business Days prior to such filing) and
(if requested by any such person) confirm such notice in writing no later than
three (3) Business Days following the day (i): (A) when a prospectus or any
prospectus supplement or post-effective amendment to the Registration Statement
is proposed to be filed; (B) whenever the SEC notifies the Company whether there
will be a "review" of such Registration Statement; (C) whenever the Company
receives (or a representative of the Company receives on its behalf) any oral or
written comments from the SEC in respect of a Registration Statement (copies or,
in the case of

                                        5
<PAGE>
oral comments, written or oral summaries of such comments shall be promptly
furnished by the Company to Subscriber's Counsel); and (D) with respect to the
Registration Statement or any post- effective amendment, when the same has
become effective; (ii) of any request by the SEC or any other Federal or state
governmental authority for amendments or supplements to the Registration
Statement or the prospectus or for additional information; (iii) of the issuance
by the SEC of any stop order suspending the effectiveness of the Registration
Statement covering any or all of the Registrable Securities or the initiation of
any proceedings for that purpose; (iv) if at any time any of the representations
or warranties of the Company contained in any agreement (including any
securities purchase agreement) contemplated hereby ceases to be true and correct
in all material respects; (v) of the receipt by the Company of any notification
with respect to the suspension of the qualification or exemption from
qualification of any of the Registrable Securities for sale in any jurisdiction,
or the initiation or threatening of any proceeding for such purpose; and (vi) of
the occurrence of any event that to the knowledge of the Company makes any
statement made in the Registration Statement or the prospectus or any document
incorporated or deemed to be incorporated therein by reference untrue in any
material respect or that requires any revisions to the Registration Statement,
the prospectus or other documents so that, in the case of the Registration
Statement or the prospectus, as the case may be, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. In addition, the
Company shall furnish Subscriber's Counsel with copies of all intended written
responses to the comments contemplated in clause (c) of this Section not later
than one (1) Business Day in advance of the filing of such responses with the
SEC so that Subscriber shall have the opportunity to comment thereon.

        (e) Furnish to Subscriber, (i) promptly after the same is prepared and
publicly distributed, filed with the SEC, or received by the Company, one (1)
copy of the Registration Statement, each preliminary prospectus and the
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 the Subscriber may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by the Subscriber;

        (f) Use all diligent efforts to (i) register and/or qualify the
Registrable Securities covered by the Registration Statement under such other
securities or blue sky laws of such jurisdictions as the Subscriber may
reasonably request and in which significant volumes of shares of Common Stock
are traded, (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 at all
times during the Registration Period, (iii) take such other actions as may be
necessary to maintain such registrations and qualification 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(f), (B)

                                        6
<PAGE>
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 more than nominal expense or burden to the Company or
(E) make any change in its charter or by-laws or any then existing contracts,
which in each case the Board of Directors of the Company determines to be
contrary to the best interests of the Company and its stockholders;

        (g) As promptly as practicable after becoming aware of such event,
notify the Subscriber of the happening of any event of which the Company has
knowledge, as a result of which the prospectus included in the Registration
Statement, as then in effect, includes any untrue statement of a material fact
or omits to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, or the Registration Statement is not otherwise
effective (each a"Registration Default"), and uses all diligent efforts to
promptly prepare a supplement or amendment to the Registration Statement or
other appropriate filing with the SEC to correct such untrue statement or
omission, and any other necessary steps to cure the Registration Default, and
deliver a number of copies of such supplement or amendment to the Subscriber as
the Subscriber may reasonably request. Failure to cure the Registration Default
within ten (10) business days shall result in the Company incurring a liquidated
damage penalty of $1,000 per day for so long as more than 10,000 shares of
Common Stock are held by the Subscriber;

        (h) As promptly as practicable after becoming aware of such event,
notify the Subscriber (or, in the event of an underwritten offering, the
managing underwriters) of the issuance by the SEC of any notice of effectiveness
or any stop order or other suspension of the effectiveness of the Registration
Statement at the earliest possible time;

        (i) Notwithstanding the foregoing, if at any time or from time to time
after the date of effectiveness of the Registration Statement, the Company
notifies Subscriber in writing of the existence of a Potential Material Event
("Blackout Notice"), Subscriber shall not offer or sell any Registrable
Securities, or engage in any other transaction involving or relating to the
Registrable Securities, from the time of the giving of notice with respect to a
Potential Material Event until Subscriber receives written notice from the
Company that such Potential Material Event either has been disclosed to the
public or no longer constitutes a Potential Material Event; PROVIDED, HOWEVER,
that (a) the Company may not so suspend the right to such holders of Registrable
Securities for more than two five (5) day periods in the aggregate during any
12-month period ("Blackout Period") with at least a ten (10) Business Day
interval between such periods, during the periods the Registration Statement is
required to be in effect, or (b) that if such Blackout Period exceeds the
permitted five (5) day periods, the Company shall pay damages of 2% of the cost
of all common stock then held by the Subscriber for each fifteen (15) day period
or portion thereof, beginning on the date of the suspension.

        (j) Use its commercially reasonable efforts, if eligible, either to (i)
cause all the Registrable Securities covered by the Registration Statement to be
listed on a national securities exchange and on each additional national
securities exchange on which securities of the same class or series issued by

                                        7
<PAGE>
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) secure
designation of all the Registrable Securities covered by the Registration
Statement as a National Association of Securities Dealers Automated Quotations
System ("Nasdaq) "Small Capitalization" within the meaning of Rule 11Aa2-1 of
the SEC under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and the quotation of the Registrable Securities on the Nasdaq Small Cap
Market; or if, despite the Company's commercially reasonable efforts to satisfy
the preceding clause (i) or (ii), the Company is unsuccessful in doing so, to
secure NASD authorization and quotation for such Registrable Securities on the
over-the-counter bulletin board 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.

        (k) Provide a transfer agent for the Registrable Securities not later
than the Subscription Date of the Registration Statement;

        (l) Cooperate with the Subscriber to facilitate the timely preparation
and delivery of certificates for the Registrable Securities to be offered
pursuant to the Registration Statement and enable such certificates for the
Registrable Securities to be in such denominations or amounts as the case may
be, as the Subscriber may reasonably request and registration in such names as
the Subscriber may request; and, within five (5) business days after a
Registration Statement which includes Registrable Securities is ordered
effective by the SEC, the Company shall deliver, and shall cause legal counsel
selected by the Company to deliver, to the transfer agent for the Registrable
Securities (with copies to the Subscriber) an appropriate instruction and
opinion of such counsel, if so required by the Company's transfer agent; and

        (m) Take all other reasonable actions necessary to expedite and
facilitate distribution to the Subscriber of the Registrable Securities pursuant
to the Registration Statement.

        4. OBLIGATIONS OF THE SUBSCRIBER. In connection with the registration of
the Registrable Securities, the Subscriber 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 the Subscriber that the Subscriber shall timely
furnish 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, as shall be reasonably required to effect the
registration of such Registrable Securities and shall timely execute such
documents in connection with such registration as the Company may reasonably
request At least ten (10) days prior to the first anticipated filing date of the
Registration Statement, the Company shall notify each Subscriber of the
information the Company requires from each such Subscriber (the "Requested
Information") if such Subscriber has any Registrable Securities included in the
Registration Statement. If at least two (2) business days prior to the filing
date the Company has not received the Requested Information from an Subscriber
(a "Non-Responsive Subscriber"), then

                                        8
<PAGE>
the Company may file the Registration Statement without including Registrable
Securities of such Non-Responsive Subscriber. Once the Company has received the
Requested Information it shall within ten (10) days file either an amendment to
the Registration Statement or a new Registration Statement. All reasonable
expenses incurred in connection with the filing of the amendment to the
Registration Statement or a new Registration Statement in terms of this SECTION
4(A) shall be borne by the Non-Responsive Subscriber.

        (b) The Subscriber by such Subscriber'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 the Registration
Statement hereunder; and

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

        5. EXPENSES OF REGISTRATION. (a) All reasonable expenses other than
underwriting discounts and commissions incurred in connection with
Registrations, filings or qualifications pursuant to SECTION 3, including,
without limitation, all Registration, listing, and qualifications fees, printers
and accounting fees, the fees and disbursements of counsel for the Company and a
fee for a single counsel for Subscriber of $3,500 for the initial Registration
Statement and $2,000 for each Amendment or Additional Registration Statement
covering the Registrable Securities shall be borne by the Company.

        6. INDEMNIFICATION. After Registrable Securities are included in a
Registration Statement under this Agreement:

        (a) To the extent permitted by law, the Company will indemnify and hold
harmless, the Subscriber, the directors, if any, of such Subscriber, the
officers, if any, of such Subscriber, each person, if any, who controls the
Subscriber within the meaning of the Securities Act or the Exchange Act (each,
an "Indemnified Person"), against any losses, claims, damages, liabilities or
expenses (joint or several) incurred (collectively, "Claims") to which any of
them may become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such Claims (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any post-effective amendment thereof or 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, (ii) any
untrue statement or alleged untrue statement of a material fact contained in any
preliminary prospectus if used prior to the Subscription Date of such
Registration Statement, or contained in the final prospectus (as

                                        9
<PAGE>
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 the
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
Securities Act, the Exchange Act, any state securities law or any rule or
regulation under the Securities Act, the Exchange Act or any state securities
law (the matters in the foregoing clauses (i) through (iii) being collectively
referred to as "Violations"). The Company shall reimburse the Subscriber,
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) shall not (i) apply to any Claims 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 or on behalf of any
Indemnified Person expressly for use in connection with the preparation of the
Registration Statement or any such amendment thereof or supplement thereto, if
such prospectus was timely made available by the Company pursuant to Section
3(b) hereof; (ii) with respect to any preliminary prospectus, inure to the
benefit of any such person from whom the person asserting any such Claim
purchased the Registrable Securities that are the subject thereof (or to the
benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus was corrected
in the prospectus, as then amended or supplemented, if such prospectus was
timely made available by the Company pursuant to Section 3(b) hereof; (iii) be
available to the extent such Claim is based on a failure of the Subscriber to
deliver or cause to be delivered the prospectus made available by the Company;
or (iv) 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. The Subscriber will indemnify the Company, its
officers, directors and agents (including legal counsel) against any claims
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 or on behalf
of such Subscriber, expressly for use in connection with the preparation of the
Registration Statement, subject to such limitations and conditions set forth in
the previous sentence. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of the Indemnified Person
or Indemnified Party.

        (b) Promptly after receipt by an Indemnified Person under this Section 6
of notice of the commencement of any action (including any governmental action),
such Indemnified Person 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, as the case may be; PROVIDED,
HOWEVER, that an Indemnified Person shall have the right to retain its own
counsel with the reasonable 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 and the
indemnifying party would be inappropriate due to actual or potential differing
interests

                                       10
<PAGE>
between such Indemnified Person and any other party represented by such counsel
in such proceeding. In such event, the Company shall pay for only one separate
legal counsel for the Subscriber selected by the Subscriber. 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 under this Section 6, except to the extent
that the indemnifying party is 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.

        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 (a) 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; (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation; and (c)
contribution 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 EXCHANGE ACT. With a view to making available to the
Subscriber the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the
Subscriber to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to use its reasonable best efforts 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 Exchange Act; and

        (c) furnish to the Subscriber so long as the Subscriber 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 Securities Act
and the Exchange 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
Subscribers to sell such securities pursuant to Rule 144 without registration.

        9. MISCELLANEOUS.

        (a) REGISTERED OWNERS. 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

                                       11
<PAGE>
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) RIGHTS CUMULATIVE; WAIVERS. The rights of each of the parties under
this Agreement are cumulative. Any provision of this Agreement may be amended
and the observance thereof may be waived (either generally or in a particular
instance and either retroactively or prospectively), only with the written
consent of the Company and Subscribers who hold a sixty-seven (67%) percent
interest of the Registrable Securities (as calculated by the stated value of the
Preferred Stock without any reference to the Warrant Shares). Any amendment or
waiver effected in accordance with this Section 9(b) shall be binding upon each
Subscriber and the Company. Any failure to exercise or any delay in exercising
any of such rights shall not operate as a waiver or variation of that or any
other such right. Any defective or partial exercise of any of such rights shall
not preclude any other or further exercise of that or any other such right. No
act or course of conduct or negotiation on the part of any party shall in any
way preclude such party from exercising any such right or constitute a
suspension or any variation of any such right.

        (c) BENEFIT; SUCCESSORS BOUND. This Agreement and the terms, covenants,
conditions, provisions, obligations, undertakings, rights, and benefits hereof,
shall be binding upon, and shall inure to the benefit of, the undersigned
parties and their heirs, executors, administrators, representatives, successors,
and permitted assigns.

        (d) ENTIRE AGREEMENT. This Agreement contains the entire agreement
between the parties with respect to the subject matter hereof. There are no

covenants or representations, oral or written, express or implied, between them
with respect to this Agreement or the matters described in this Agreement,
except as set forth in this Agreement and in the other documentation relating to
the transactions contemplated by this Agreement. Any such negotiations,
promises, or understandings shall not be used to interpret or constitute this
Agreement.

        (e) ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the
Company register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the Subscribers to any transferee of the Registrable
Securities (or all or any portion of any unconverted Preferred Stock or
unexercised Warrant) only if: (a) the Subscriber 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, (b) the
Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (i) the name and address of such transferee or
assignee and (ii) the securities with respect to which such registration rights
are being transferred or assigned, (c) immediately following such transfer or
assignment the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act and applicable state securities
laws, (d) at or before the time the Company received the written notice
contemplated by clause (b) of this sentence the transferee or assignee agrees in
writing with the Company to be bound by all of the provisions

                                       12
<PAGE>
contained herein, and (e) such transfer of Registrable Securities is completed
and disclosed to the Company prior to the initial Effective Date or involves the
transfer of Registrable Securities resulting from the conversion of Preferred
Stock having a stated value of at least $200,000. In the event of any delay in
filing or effectiveness of the Registration Statement as a result of such
assignment, the Company shall not be liable for any damages arising from such
delay, or the payments set forth in Section 2(b) hereof arising from such delay.

        (f) SEVERABILITY. Each part of this Agreement is intended to be
severable. In the event that any provision of this Agreement is found by any
court or other authority of competent jurisdiction to be illegal or
unenforceable, such provision shall be severed or modified to the extent
necessary to render it enforceable and as so severed or modified, this Agreement
shall continue in full force and effect.

        (g) Notices required or permitted to be given hereunder shall be given
in the manner contemplated by the Securities Purchase Agreement, (i) if to the
Company or to the Initial Subscriber, to their respective address contemplated
by the Securities Purchase Agreement, and (ii) if to any other Subscriber, at
such address as such Subscriber shall have provided in writing to the Company,
or at such other address as each such party furnishes by notice given in
accordance with this Section 9(h).

conflicts of laws rules or principles. Each of the parties consents to the
exclusive jurisdiction of the federal courts of the State of Delaware in

Agreement and the transactions contemplated hereby.

                               FORM OF WARRANT

      THESE SECURITIES (THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE
      AND MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE
      REGISTRATION STATEMENT FOR THE SECURITIES OR AN OPINION OF COUNSEL OR
      OTHER EVIDENCE ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT
      REQUIRED.

                            HENLEY HEALTHCARE, INC.

                        COMMON STOCK PURCHASE WARRANT

            1. ISSUANCE; CERTAIN DEFINITIONS. In consideration of good and
valuable consideration, the receipt of which is hereby acknowledged by HENLEY
HEALTHCARE, INC., a Texas corporation (the "Company"),________________ or
registered assigns (the "Holder") is hereby granted the right to purchase at any
time until 5:00 P.M., New York City time, on ________, 200_(1) (the "Expiration
Date"), _________________ Thousand (_______) (2) fully paid and nonassessable
shares of the Company's Common Stock, $____ par value per share (the "Common
Stock") at an initial exercise price per share (the "Exercise Price") of $
_____(3) per share, subject to further adjustment as set forth herein. This
Warrant is being issued pursuant to the terms of that certain Securities
Purchase Agreement, dated as of October _____, 2000 (the "Securities Purchase
Agreement"), to which the Company and Holder (or Holder's predecessor in
interest) are parties. Capitalized terms not otherwise defined herein shall have
the meanings ascribed to them in the Securities Purchase Agreement.

--------

      (1) Insert date which is last day of month in which fifth anniversary of
the Closing Date occurs.

      (2) Insert (x) 50% of the number of shares issued at the the aggregate
stated value of the Preferred Stock issued to the Buyer on the relevant Closing
Date divided by (y) the Fixed Conversion Price (as defined in Certificate of
Designations).

      (3) Insert 110% of the Fixed Conversion Price (as defined in Certificate
of Designations)

                                      1
<PAGE>
            2. EXERCISE OF WARRANTS. (This Warrant is exercisable in whole or in
part at the Exercise Price per share of Common Stock payable hereunder, payable
in cash or by certified or official bank check, or by "cashless exercise", by
means of tendering this Warrant Certificate to the Company to receive a number
of shares of Common Stock equal in Market Value to the difference between the
aggregate Market Value of the shares of Common Stock issuable upon exercise of
this Warrant and the total cash exercise price thereof divided by the Market
Price. Upon surrender of this Warrant Certificate with the annexed Notice of
Exercise Form duly executed, together with payment of the Exercise Price for the
shares of Common Stock purchased, the Holder shall be entitled to receive a
certificate or certificates for the shares of Common Stock so purchased. For the
purposes of this Section 2, "Market Value" shall be an amount equal to the
closing price of a share of Common Stock for the day preceding the Company's
receipt of the Notice of Exercise Form duly executed (the "Market Price")
multiplied by the number of shares of Common Stock to be issued upon surrender
of this Warrant Certificate.

                  (b) For purposes of Rule 144 promulgated under the Securities
Act, it is intended, understood and acknowledged that the Warrant Shares issued
in a cashless exercise transaction shall be deemed to have been acquired by the
Holder and the holding period for the Warrant Shares shall be deemed to have
been commenced, on the issue date

                  (c) Notwithstanding the provisions of this Warrant, or of the
other Transaction Agreements (as defined in the Securities Purchase Agreement),
in no event (except (i) with respect to an mandatory conversion, if any, of the
Preferred Stock as provided in the Certificate of Designations, (ii) as
specifically provided in the Certificate of Designations as an exception to this
provision, or (iii) if the Company is in default hereunder or under any of the
Transaction Agreements, and the Holder has asserted such default in writing and
the applicability of this provision to such default) shall the Holder be
entitled to exercise this Warrant or shall the Company have the obligation, to
issue shares upon such exercise of all or any portion of this Warrant to the
extent that, after such conversion, the sum of (1) the number of shares of
Common Stock beneficially owned by the Holder and its affiliates (other than
shares of Common Stock which may be deemed beneficially owned through the
ownership of the unconverted portion of the Preferred Stock or unexercised
portion of the Warrants), and (2) the number of shares of Common Stock issuable
upon the conversion of the Preferred Stock or exercise of the Warrants with
respect to which the determination of this proviso is being made, would result
in beneficial ownership by the Holder and its affiliates of more than 9.99% of
the outstanding shares of Common Stock (after taking into account the shares to
be issued to the Holder upon such conversion or exercise). For purposes of the
proviso to the immediately preceding sentence, beneficial ownership shall be
determined in accordance with Section 13(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act"), except as otherwise provided in clause (1) of
such sentence.

                                      2
<PAGE>
            3. RESERVATION OF SHARES. The Company hereby agrees that at all
times during the term of this Warrant there shall be reserved for issuance upon
exercise of this Warrant such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").

            4. MUTILATION OR LOSS OF WARRANT. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) receipt of
reasonably satisfactory indemnification and affidavit, and (in the case of
mutilation) upon surrender and cancellation of this Warrant, the Company will
execute and deliver a new Warrant of like tenor and date and any such lost,
stolen, destroyed or mutilated Warrant shall thereupon become void.

            5. RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

            6. PROTECTION AGAINST DILUTION.

                  6.1 ADJUSTMENT MECHANISM. If an adjustment of the Exercise
Price is required pursuant to this Section 6, the Holder shall be entitled to
purchase such number of additional shares of Common Stock as will cause (i) the
total number of shares of Common Stock Holder is entitled to purchase pursuant
to this Warrant, multiplied by (ii) the adjusted Exercise Price per share, to
equal (iii) the dollar amount of the total number of shares of Common Stock
which the Holder is entitled to purchase before adjustment, multiplied by the
total Exercise Price before adjustment.

                  6.2 CAPITAL ADJUSTMENTS. In case of any stock split or reverse
stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of this Section 6 shall be
applied as if such capital adjustment event had occurred immediately prior to
the date of this Warrant and the original Exercise Price had been fairly
allocated to the stock resulting from such capital adjustment; and in other
respects the provisions of this Section shall be applied in a fair, equitable
and reasonable manner so as to give effect, as nearly as may be, to the purposes
hereof. A rights offering to stockholders shall be deemed a stock dividend to
the extent of the bargain purchase element of the rights.

                  6.3 ADJUSTMENT FOR SPIN OFF. If, for any reason, prior to the
exercise of this Warrant in full, the Company spins off or otherwise divests
itself of a part of its business or operations or disposes all or of a part of
its assets in a transaction (the "Spin Off") in which the Company does not
receive compensation for such business, operations or assets, but causes
securities of another entity (the "Spin Off Securities") to be issued to
security holders of the Company, then

                                      3
<PAGE>
            (a) the Company shall cause (i) to be reserved Spin Off Securities
      equal to the number thereof which would have been issued to the Holder had
      all of the Holder's unexercised Warrants outstanding on the record date
      (the "Record Date") for determining the amount and number of Spin Off
      Securities to be issued to security holders of the Company (the
      "Outstanding Warrants") been exercised as of the close of business on the
      trading day immediately before the Record Date (the "Reserved Spin Off
      Shares"), and (ii) to be issued to the Holder on the exercise of all or
      any of the Outstanding Warrants, such amount of the Reserved Spin Off
      Shares equal to (x) the Reserved Spin Off Shares multiplied by (y) a
      fraction, of which (I) the numerator is the amount of the Outstanding
      Warrants then being exercised, and (II) the denominator is the amount of
      the Outstanding Warrants; and

            (b) the Exercise Price on the Outstanding Warrants shall be adjusted
      immediately after consummation of the Spin Off by multiplying the Exercise
      Price by a fraction (if, but only if, such fraction is less than 1.0), the
      numerator of which is the Average Market Price of the Common Stock (as
      defined below) for the five (5) trading days immediately following the
      fifth trading day after the Record Date, and the denominator of which is
      the Average Market Price of the Common Stock on the five (5) trading days
      immediately preceding the Record Date; and such adjusted Exercise Price
      shall be deemed to be the Exercise Price with respect to the Outstanding
      Warrants after the Record Date. As used herein, the term "Average Market
      Price of the Common Stock" means the average closing bid price of a share
      of Common Stock, as reported by Bloomberg, LP or, if not so reported, as
      reported by the securities exchange or automated system on which the
      Common Stock is listed or on the over-the-counter market for the relevant
      date.

            7. TRANSFER TO COMPLY WITH THE SECURITIES ACT; REGISTRATION RIGHTS.

                  7.1 TRANSFER. This Warrant has not been registered under the
Securities Act of 1933, as amended, (the "Act") and has been issued to the
Holder for investment and not with a view to the distribution of either the
Warrant or the Warrant Shares. Neither this Warrant nor any of the Warrant
Shares or any other security issued or issuable upon exercise of this Warrant
may be sold, transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel satisfactory to the Company that registration is not required under the
Act. Each certificate for the Warrant, the Warrant Shares and any other security
issued or issuable upon exercise of this Warrant shall contain a legend on the
face thereof, in form and substance satisfactory to counsel for the Company,
setting forth the restrictions on transfer contained in this Section.

                  7.2 REGISTRATION RIGHTS. (a) Reference is made to the
Registration Rights Agreement. The Company's obligations under the Registration
Rights Agreement and the other terms and conditions thereof with respect to the
Warrant Shares, including, but not necessarily limited to, the Company's
commitment to file a registration statement including the Warrant Shares,

                                      4
<PAGE>
to have the registration of the Warrant Shares completed and effective, and to
maintain such registration, are incorporated herein by reference.

                  (b) In addition to the registration rights referred to in the
preceding provisions of Section 7.2(a), effective after the expiration of the
effectiveness of the Registration Statement as contemplated by the Registration
Rights Agreement, the Holder shall have piggy-back registration rights with
respect to the Warrant Shares then held by the Holder or then subject to
issuance upon exercise of this Warrant (collectively, the "Remaining Warrant
Shares"), subject to the conditions set forth below. If, at any time after the
Registration Statement has ceased to be effective, the Company participates
(whether voluntarily or by reason of an obligation to a third party) in the
registration of any shares of the Company's stock (other than a registration on
Form S-8), the Company shall give written notice thereof to the Holder and the
Holder shall have the right, exercisable within ten (10) business days after
receipt of such notice, to demand inclusion of all or a portion of the Holder's
Remaining Warrant Shares in such registration statement. If the Holder exercises
such election, the Remaining Warrant Shares so designated shall be included in
the registration statement at no cost or expense to the Holder (other than any
