          (i) The Holder of this Warrant, by acceptance hereof, acknowledges
     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under
     the Securities Act and any applicable state securities laws.

          (ii) Except as provided in paragraph (iii) below, this Warrant and all
     certificates representing share of Warrant Stock issued upon exercise
     hereof shall be stamped or imprinted with a legend in substantially the
     following form:

                    THIS WARRANT AND THE SHARE OF COMMON STOCK ISSUABLE UPON
                    EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE
                    SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
                    OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,
                    TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER
                    THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES
                    LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF ITS
                    COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
                    SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
                    SECURITIES LAWS IS NOT REQUIRED.

<PAGE>

          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any

<PAGE>

federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

               (i) not permit the par value, if any, of its Common Stock to
          exceed the then effective Warrant Price,

               (ii) no amend or modify an provision of the Certificate of
          Incorporation or by-laws of the Issuer in any manner that would
          adversely affect in any way the powers, preferences or relative
          participating, optional or other special rights of the Common Stock or
          which would adversely affect the rights of the Holders of the
          Warrants,

               (iii) take all such action as may be reasonably necessary in
          order that the Issuer may validly and legally issue fully paid and
          nonassessable shares of Common Stock, free and clear of any liens,
          claims, encumbrances and restrictions (other than as provided herein)
          upon the exercise of this Warrant, and

               (iv) use its best efforts to obtain all such authorizations,
          exemptions or consents from any public regulatory body having
          jurisdiction thereof as may be reasonably necessary to enable the
          Issuer to perform its obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the

<PAGE>

Issuer will make and deliver, in lieu of such lost, stolen, destroyed or
mutilated Warrant, a new Warrant of like tenor and representing the right to
purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
          Issuer shall not be the continuing or surviving corporation of such
          consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
          Issuer and the Issuer shall be the continuing or surviving Person but,
          in connection with such consolidation or merger, any Capital Stock of
          the Issuer shall be changed into or exchanged for Securities of any
          other Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
          to any other Person, or

               (d) effect a capital reorganization or reclassification of its
          Capital Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the

<PAGE>

adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

     (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer
under this Warrant (and if the Issuer shall survive the consummation of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from, and continuing obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance with the foregoing provisions of this subsection
(a), such Holder shall be entitled to receive, and such Person shall have
similarly delivered to such Holder an opinion of counsel for such Person, which
counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of the subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to delivery upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

     (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a  combination  of shares,

<PAGE>

the Warrant Price shall be proportionately increased (as at the effective date
of such combination or, if the Issuer shall take a record of Holders of its
Common Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately

<PAGE>

after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.

<PAGE>

          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>

     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable

of any agreement contained herein or by an injunction against a violation of any
of the terms hereof or otherwise.

shall inure to the benefit of and be binding upon the successors and assigns of

Warrant Stock issued pursuant hereto, and shall be enforceable by any such
Holder or Holder of Warrant Stock.

agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     15. Headings. The headings of the Sections of this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

     IN WITNESS WHEREOF, the Issuer has executed this Warrant as of the day and

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.

<PAGE>

     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

<PAGE>

employment 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.

<PAGE>

     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

                    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
Britannica Associates Limited (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:_______________________________
