Securities for an offering to be made on a continuous basis pursuant to Rule
415. The Registration Statement shall be on Form S-3 (except if the Company is
not then eligible to register for resale the Registrable Securities on Form S-3,
in which case such registration shall be on another appropriate form in

Commission as soon as possible, but in no event later than forth-five (45) days

     3. Registration Procedures.

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

          (a) Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement on Form S-3 (or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith) in
accordance with the method or methods of distribution thereof as specified by
the Holders (except if otherwise directed by the Holders), and cause the
Registration Statement to become effective and remain effective as provided
herein; provided, however, that not less than five (5) Business Days prior to
the filing of the Registration Statement or any related Prospectus or any
amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall (i) furnish to the Holders
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of such Holders and such Special Counsel, and (ii) at the request of
any Holder cause its officers and directors, counsel and independent certified
public accountants to respond to such inquiries as shall be necessary, in the
reasonable opinion of counsel to such Holders, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file the Registration Statement or any such Prospectus or any amendments or
supplements thereto to which the Holders of a majority of the Registrable
Securities or any Special Counsel shall reasonably object in writing within
three (3) Business Days of their receipt thereof.

          (b) (i) Prepare and file with the Commission such amendments,
including post- effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holders true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

<PAGE>


          (c) Notify the Holders of Registrable Securities to be sold and any
Special Counsel as promptly as possible (and, in the case of (i)(A) below, not
less than five (5) Business Days prior to such filing) and (if requested by any
such Person) confirm such notice in writing no later than one (1) Business Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

          (d) Use its best efforts to avoid the issuance of, or if issued,
obtain the withdrawal of, (i) any order suspending the effectiveness of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment.

          (e) If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment.

          (f) Furnish to each Holder and any Special Counsel, without charge, at
least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

<PAGE>


          (g) Promptly deliver to each Holder and any Special Counsel, without
charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

          (h) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
any Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

          (i) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to a Registration Statement, which certificates shall be free of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any Holder may request at least
two (2) Business Days prior to any sale of Registrable Securities.

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

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

          (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions os Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period (or 90 days after the end of any 12-month period if such period is a




<PAGE>


fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

          (m) The Company may require each selling Holder to furnish to the
Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement, and the Company may exclude from such registration the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until Such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

          (n) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement or suspension shall be permitted for consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

     4. Registration Expenses

          All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company whether or not
the Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with the OTC
Bulletin Board and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings
required to be made with the Commission, (C) with respect to filings required to
be made under Nasdaq SmallCap Market Rules and (C) in compliance with state
securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the Holders in connection with Blue Sky
qualifications of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such
jurisdictions as the Holders of a majority of Registrable Securities may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is requested by the holders of a majority of the
Registrable Securities included in the Registration Statement), (iii) messenger,
telephone and delivery expenses, (iv) fees and disbursements of counsel for the
Company and Special Counsel for the Holders, in the case of the Special Counsel,
to a maximum amount of $10,000, (v) Securities Act liability insurance, if the
Company so desires such insurance, and (vi) fees and expenses of all other
Persons retained by the Company in connection with the consummation of the
transactions contemplated by this Agreement, including, without limitation, the
Company's independent public accountants (including the expenses of any comfort
letters or costs associated with the delivery by independent public accountants
of a comfort letter or comfort letters). In addition, the Company shall be
responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder.


     5. Indemnification

          (a) Indemnification by the Company. The Company shall, notwithstanding
any termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to
perform under a margin call of Common Stock), investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, to
the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation,



<PAGE>


costs of preparation and attorneys' fees) and expenses (collectively, "Losses"),
as incurred, arising out of or relating to any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based solely upon
information regarding such Holder furnished in writing to the Company by such
Holder expressly for use therein, which information was reasonably relied on by
the Company for use therein or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus or in any amendment or supplement thereto. The Company shall notify
the Holders promptly of the institution, threat or assertion of any Proceeding
of which the Company is aware in connection with the transactions contemplated
by this Agreement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of an Indemnified Party and
shall survive the transfer of the Registrable Securities by the Holders.

          (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or arising solely out of or based solely upon any omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus and that such information was reasonably relied
upon by the Company for use in the Registration Statement, such Prospectus or
such form of prospectus or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus. Notwithstanding anything to the contrary contained herein, the
Holder shall be liable under this Section 5(b) for only that amount as does not
exceed the net proceeds to such Holder as a result of the sale of Registrable
Securities pursuant to such Registration Statement.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment



<PAGE>


of counsel reasonably satisfactory to the Indemnified Party and the payment of
all fees and expenses incurred in connection with defense thereof; provided,
that the failure of any Indemnified Party to give such notice shall not relieve
the Indemnifying Party of its obligations or liabilities pursuant to this
Agreement, except (and only) to the extent that it shall be finally determined
by a court of competent jurisdiction (which determination is not subject to
appeal or further review) that such failure shall have proximately and
materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

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

          (d) Contribution. If a claim for indemnification under Section 5(a) or
5(b) is unavailable to an Indemnified Party because of a failure or result of a
governmental authority to enforce such indemnification in accordance with its
terms (by reason of public policy or otherwise), then each Indemnifying Party,
in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions, statements or
omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified



<PAGE>


Party shall be determined by reference to, among other things, whether any
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission of a material fact, has been taken
or made by, or relates to information supplied by, such Indemnifying Party, or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in
this Section was available to such party in accordance with its terms.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable or required to contribute under this Section 5(c) for only that amount as
does not exceed the net proceeds to such Holder as a result of the sale of
Registrable Securities pursuant to such Registration Statement.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6. Rule 144.

          As long as any Holder owns Common Stock, Warrants or Warrant Shares,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act and to promptly furnish the Holders with true and complete copies
of all such filings. As long as any Holder owns Common Stock, Warrants or
Warrant Shares, if the Company is not required to file reports pursuant to
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the
Holders and make publicly available in accordance with Rule 144(c) promulgated
under the Securities Act annual and quarterly financial statements, together
with a discussion and analysis of such financial statements in form and
substance substantially similar to those that would otherwise be required to
have been made under the Exchange Act. The Company further covenants that it
will take such further action as any Holder may reasonably request, all to the
extent required from time to time to enable such Person to sell Common Stock and
Warrant Shares without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act, including providing any legal opinions referred to in the
Purchase Agreement. Upon the request of any Holder, the Company shall deliver to
such Holder a written certification of a duly authorized officer as to whether
it has complied with such requirements.

     7. Miscellaneous.

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

          (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof entered into and currently in effect,
nor shall the Company or any of its subsidiaries, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Without limiting the generality
of the foregoing, without the written consent of the Holders of a majority of
the then outstanding Registrable Securities, the Company shall not grant to any
Person the right to request the Company to register any securities of the
Company under the Securities Act unless the right so granted are subject in all
respects to the prior rights in full of the Holders set forth herein, and are
not otherwise in conflict with the provisions of this Agreement, or the
Registration Rights Agreement has been declared effective by the SEC.

          (c) No Piggyback on Registrations. Neither the Company nor any of its
security holders (other than the Holders in such capacity pursuant hereto and
the Persons listed on Schedule 7(c) hereto) may include securities of the
Company in the Registration Statement, and the Company shall not after the date
hereof enter into any agreement providing such right to any of its security
holders, unless the right so granted is subject in all respects to the prior
rights in full of the Holders set forth herein, and is not otherwise in conflict
with the provisions of this Agreement.

          (d) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) the Shares of Common Stock or (ii)
the Warrant Shares, the Company shall determine to prepare and file with the
Commission a registration statement relating to an offering for its own account
or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or its then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, the Company shall send to each holder of Registrable Securities
written notice of such determination and, if within thirty (30) days after
receipt of such notice, any such holder shall so request in writing (which
request shall specify the Registrable Securities intended to be disposed of by
the Purchasers), the Company will cause the registration under the Securities
Act of all Registrable Securities which the Company has been so requested to
register by the holder, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to



<PAGE>


the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to such holder and, thereupon, (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities being registered pursuant to
this Section 7(d) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 7(d) that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the managing
underwriter should reasonably determine that the inclusion of such Registrable
Securities, would materially adversely affect the offering contemplated in such
registration statement, and based on such determination recommends inclusion in
such registration statement of fewer or none of the Registrable Securities of
the Holders, then (x) the number of Registrable Securities of the Holders
included in such registration statement shall be reduced pro-rata among such
Holders (based upon the number of Registrable Securities requested to be
included in the registration), if the Company after consultation with the
underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y)
none of the Registrable Securities of the Holders shall be included in such
registration statement, if the Company after consultation with the
underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other
persons or entities as well as the Company, such reduction shall not represent a
greater fraction of the number of Registrable Securities intended to be offered
by the Holders than the fraction of similar reductions imposed on such other
persons or entities (other than the Company).

          (e) Failure to File Registration Statement and Other Events. The
Company and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Time or if
certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or prior to the
Filing Date, (or is not declared effective by the Commission on or prior to the
Effectiveness Date or in the event an additional Registration Statement is filed
because the actual number of shares of Common Stock into which the Warrants are
exercisable exceeds the number of shares of Common Stock initially registered is
not filed and declared effective within the time periods set forth in Section
2(a)), or (ii) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 12dl-2 promulgated under the Exchange Act
within five (5) Business Days of the date that the Company is notified (orally
or in writing, whichever is earlier) by the Commission that a Registration
Statement will not be "reviewed," or not subject to further review, or (iii) the
Registration Statement is filed with and declared effective by the Commission




<PAGE>


but thereafter ceases to be effective as to all Registrable Securities at any
time prior to the expiration of the Effectiveness Period, without being
succeeded immediately by a subsequent Registration Statement filed with and
declared effective by the Commission, and such cessation continues for a period
of thirty days after written notice thereof to the Company, or (iv) trading in
the Common Stock shall be suspended or if the Common Stock is delisted from the
Nasdaq SmallCap Market for any reason for more than three Business Days in the
aggregate, and such suspension or delisting continues for a period of fourteen
days after written notice thereof to the Company, or (v) the Company breaches in
a material respect any covenant or other material term or condition to this
Agreement, Purchase Agreement (other than a representation or warranty contained
therein) or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated hereby and thereby,
and such breach continues for a period of thirty days after written notice
thereof to the Company, or (vii) the Company has breached Section 3(n) of this
Agreement (any such failure or breach being referred to as an ("Event"), the
Company shall pay in cash as liquidated damages for such failure and not as a
penalty to each Holder an amount equal to 2% of such Holder's pro rata share of
the purchase price paid by all Holders for all shares of Common Stock purchased
and then outstanding pursuant to the Purchase Agreement for each thirty (30) day
period until the applicable Event has been cured, which shall be pro rated for
such periods less than thirty (30) days (the "Periodic Amount"). Payments to be
made pursuant to this Section 7(e) shall be due and payable in cash immediately
upon demand. The parties agree that the Periodic Amount represents a reasonable
estimate on the part of the parties, as of the date of this Agreement, of the
amount of damages that may be incurred by the Holders if the Registration
Statement is not filed on or prior to the Filing Date or has not been declared
effective by the Commission on or prior to the Effectiveness Date and maintained
in the manner contemplated herein during the Effectiveness Time or if any other
Event as described herein has occurred.

          (f) Specific Enforcement, Consent to Jurisdiction.

               (i) The Company and the Purchasers acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Registration Rights Agreement or the Purchase Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Registration
Rights Agreement or the Purchase Agreement and to enforce specifically the terms
and provisions hereof or thereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

               (ii) Each of the Company and the Purchasers (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the Southern District of New York for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement or the
Purchase Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is improper.
Each of the Company and the Purchasers consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 7(f) shall affect or limit any right to serve
process in any other manner permitted by law.

including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and each of the Holders. Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders and that does not directly or indirectly
affect the rights of other Holders may be given by Holders of at least a
majority of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the
immediately preceding sentence.

          (j) Assignment of Registration Rights. The rights of each Holder
hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
automatically assignable by the Holder to any transferee of such Holder of all

rights, and a copy of such agreement is furnished to the Company within a

                    Re: Pollution Research and Control Corp.
                        ------------------------------------

Ladies and Gentlemen:

          We are counsel to Pollution Research and Control Corp., a California
corporation (the "Company"), and have represented the Company in connection with
(i) that certain Debenture (the "Debenture") issued by the Company in favor of
The Venezuela Recovery Fund, N.V. (the "Holder") which Debenture is convertible
into shares of the Company's common stock, par value $.01 per share (the "Common
Stock"), and (ii) warrants issued to the Holder to purchase shares of the Common
Stock (the "Warrants"). Pursuant to the Debenture, the Company also has entered
into a Registration Rights Agreement with the Holder (the "Registration Rights
Agreement") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined the Registration Rights
Agreement), including the shares of Common Stock issuable upon exercise of the
Warrants, under the Securities Act of 1933, as amended (the "1933 Act"). In
connection with the Company's obligations under the Registration Rights
Agreement, on _______ __, 1999, the Company filed a Registration Statement on
Form S-3 (File No. 333-____________) (the "Registration Statement") with the
Securities and Exchange Commission (the "SEC") relating to the Registrable
Securities which names each of the Holders as a selling stockholder thereunder.

          In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                              Very truly yours,

                                              [COMPANY'S COUNSEL]



                                              By:_______________________________
