                                                                     TO FORM 8-K

         THIS WARRANT AND THE SHARES ISSUABLE UPON THE EXERCISE OF THIS WARRANT
         HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
         EXCEPT AS OTHERWISE SET FORTH HEREIN OR IN A SECURITIES PURCHASE
         AGREEMENT DATED AS OF FEBRUARY 24, 2000, NEITHER THIS WARRANT NOR ANY
         OF SUCH SHARES MAY BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF

                                                               Right to Purchase
                                                             1,085,973 Shares of
                                                                   Common Stock,
                                                       par value $.005 per share

                             STOCK PURCHASE WARRANT

         THIS CERTIFIES THAT, for value received, RGC INTERNATIONAL INVESTORS,
LDC or its registered assigns, is entitled to purchase from Biospherics
Incorporated, a Delaware corporation (the "Company"), at any time or from time
to time during the period specified in Paragraph 2 hereof, One Million
Eighty-Five Thousand Nine Hundred Seventy-Three (1,085,973) fully paid and
nonassessable shares of the Company's Common Stock, par value $.005 per share
(the "Common Stock"), at an exercise price of $6.90625 per share (the "Exercise
Price"). The term "Warrant Shares," as used herein, refers to the shares of
Common Stock purchasable hereunder. The Warrant Shares and the Exercise Price
are subject to adjustment as provided in Paragraph 4 hereof. The term Warrants
means this Warrant and the other warrants issued pursuant to that certain
Securities Purchase Agreement, dated February 24, 2000, by and among the Company
and the Buyers listed on the execution page thereof (the "Securities Purchase
Agreement").

         This Warrant is subject to the following terms, provisions, and
conditions:

         1. MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.
Subject to the provisions hereof, this Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant, together with a
completed exercise agreement in the form attached hereto (the "Exercise
Agreement"), to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the holder hereof), and upon (i)
payment to the Company in cash, by certified or official bank check or by wire
transfer for the account of the

                                       26
<PAGE>

Company of the Exercise Price for the Warrant Shares specified in the Exercise
Agreement or (ii) if at any time after June 23, 2000 the resale of the Warrant
Shares by the holder is not then registered pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), delivery to the Company of a written notice of an election to
effect a "Cashless Exercise" (as defined in Section 11(c) below) for the Warrant
Shares specified in the Exercise Agreement. The Warrant Shares so purchased
shall be deemed to be issued to the holder hereof or such holder's designee, as
the record owner of such shares, as of the close of business on the date on
which this Warrant shall have been surrendered, the completed Exercise Agreement
shall have been delivered, and payment shall have been made for such shares (or
an election to effect a Cashless Exercise has been made) as set forth above.
Certificates for the Warrant Shares so purchased, representing the aggregate
number of shares specified in the Exercise Agreement, shall be delivered to the
holder hereof within a reasonable time, not exceeding three (3) business days,
after this Warrant shall have been so exercised. The certificates so delivered
shall be in such denominations as may be requested by the holder hereof and
shall be registered in the name of such holder or such other name as shall be
designated by such holder. If this Warrant shall have been exercised only in
part, then, unless this Warrant has expired, the Company shall, at its expense,
at the time of delivery of such certificates, deliver to the holder a new
Warrant representing the number of shares with respect to which this Warrant
shall not then have been exercised.

         Notwithstanding anything in this Warrant to the contrary, in no event
shall the Holder of this Warrant be entitled to exercise a number of Warrants
(or portions thereof) in excess of the number of Warrants (or portions thereof)
upon exercise of which the sum of (i) the number of shares of Common Stock
beneficially owned by the Holder and its affiliates (other than shares of Common
Stock which may be deemed beneficially owned through the ownership of the
unexercised Warrants and the unexercised or unconverted portion of any other
securities of the Company subject to a limitation on conversion or exercise
analogous to the limitation contained herein) and (ii) the number of shares of
Common Stock issuable upon exercise of the Warrants (or portions thereof) with
respect to which the determination described herein is being made, would result
in beneficial ownership by the Holder and its affiliates of more than 9.9% of
the outstanding shares of Common Stock. For purposes of the immediately
preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
13D-G thereunder, except as otherwise provided in clause (i) hereof.

         2. PERIOD OF EXERCISE. This Warrant is exercisable at any time or from
time to time on or after the date on which this Warrant is issued and delivered
pursuant to the terms of the Securities Purchase Agreement (the "Issue Date")
and before 5:00 p.m., New York City time on the fourth (4th) anniversary of the
Issue Date (the "Exercise Period").

         3. CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants and
agrees as follows:

                  (a) SHARES TO BE FULLY PAID. All Warrant Shares will, upon
issuance in accordance with the terms of this Warrant, be validly issued, fully
paid, and nonassessable and free from all taxes, liens, and charges with respect
to the issue thereof.

                                       27
<PAGE>

                  (b) RESERVATION OF SHARES. During the Exercise Period, the
Company shall at all times have authorized, and reserved for the purpose of
issuance upon exercise of this Warrant, a sufficient number of shares of Common
Stock to provide for the exercise in full of this Warrant.

                  (c) LISTING. The Company shall promptly secure the listing of
the shares of Common Stock issuable upon exercise of this Warrant upon each
national securities exchange or automated quotation system, if any, upon which
shares of Common Stock are then listed (subject to official notice of issuance
upon exercise of this Warrant) and shall maintain, so long as any other shares
of Common Stock shall be so listed, such listing of all shares of Common Stock
from time to time issuable upon the exercise of this Warrant; and the Company
shall so list on each national securities exchange or automated quotation
system, as the case may be, and shall maintain such listing of, any other shares
of capital stock of the Company issuable upon the exercise of this Warrant if
and so long as any shares of the same class shall be listed on such national
securities exchange or automated quotation system.

                  (d) CERTAIN ACTIONS PROHIBITED. The Company will not, by
amendment of its charter or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed by it hereunder, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and
in the taking of all such action as may reasonably be requested by the holder of
this Warrant in order to protect the exercise privilege of the holder of this
Warrant against dilution or other impairment, consistent with the tenor and
purpose of this Warrant. Without limiting the generality of the foregoing, the
Company (i) will not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the Exercise Price then in
effect, and (ii) will take all such actions as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and
nonassessable shares of Common Stock upon the exercise of this Warrant.

                  (e) SUCCESSORS AND ASSIGNS. This Warrant will be binding upon
any entity succeeding to the Company by merger, consolidation, or acquisition of
all or substantially all the Company's assets.

         4. ANTIDILUTION PROVISIONS. During the Exercise Period, the Exercise
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Paragraph 4. In the event that any adjustment of the
Exercise Price as required herein results in a fraction of a cent, such Exercise
Price shall be rounded up to the nearest cent.

                  (a) ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES UPON
ISSUANCE OF COMMON STOCK. Except as otherwise provided in Paragraphs 4(c) and
4(e) hereof, if and whenever on or after the Issue Date of this Warrant, the
Company issues or sells, or in accordance with Paragraph 4(b) hereof is deemed
to have issued or sold, any shares of Common Stock for no consideration or for a
consideration per share (before deduction of reasonable expenses or commissions
or underwriting discounts or allowances in connection therewith) less than the
Market Price (as hereinafter defined) on the date of issuance (or deemed
issuance) of

                                       28
<PAGE>

such Common Stock (a "Dilutive Issuance"), then immediately upon the Dilutive
Issuance, the Exercise Price will be reduced to a price determined by
multiplying the Exercise Price in effect immediately prior to the Dilutive
Issuance by a fraction, (i) the numerator of which is an amount equal to the sum
of (x) the number of shares of Common Stock actually outstanding immediately
prior to the Dilutive Issuance, plus (y) the quotient of the aggregate
consideration, calculated as set forth in Paragraph 4(b) hereof, received by the
Company upon such Dilutive Issuance divided by the Market Price in effect
immediately prior to the Dilutive Issuance, and (ii) the denominator of which is
the total number of shares of Common Stock Deemed Outstanding (as defined below)
immediately after the Dilutive Issuance.

                  (b) EFFECT ON EXERCISE PRICE OF CERTAIN EVENTS. For purposes
of determining the adjusted Exercise Price under Paragraph 4(a) hereof, the
following will be applicable:

                  (i) ISSUANCE OF RIGHTS OR OPTIONS. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities convertible into or exchangeable for Common Stock ("Convertible
Securities") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "Options") and the price
per share for which Common Stock is issuable upon the exercise of such Options
is less than the Market Price on the date of issuance or grant of such Options,
then the maximum total number of shares of Common Stock issuable upon the
exercise of all such Options will, as of the date of the issuance or grant of
such Options, be deemed to be outstanding and to have been issued and sold by
the Company for such price per share. For purposes of the preceding sentence,
the "price per share for which Common Stock is issuable upon the exercise of
such Options" shall be determined by dividing (i) the total amount, if any,
received or receivable by the Company as consideration for the issuance or
granting of all such Options, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the exercise of all such
Options, plus, in the case of Convertible Securities issuable upon the exercise
of such Options, the minimum aggregate amount of additional consideration
payable upon the conversion or exchange thereof at the time such Convertible
Securities first become convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise of all such Options
(assuming full conversion of Convertible Securities, if applicable). No further
adjustment to the Exercise Price will be made upon the actual issuance of such
Common Stock upon the exercise of such Options or upon the conversion or
exchange of Convertible Securities issuable upon exercise of such Options.

                  (ii) ISSUANCE OF CONVERTIBLE SECURITIES. If the Company in any
manner issues or sells any Convertible Securities, whether or not immediately
convertible (other than where such Convertible Securities are issuable upon the
exercise of Options), and the price per share for which Common Stock is issuable
upon such conversion or exchange is less than the Market Price on the date of
issuance of such Convertible Securities, then the maximum total number of shares
of Common Stock issuable upon the conversion or exchange of all such Convertible
Securities will, as of the date of the issuance of such Convertible Securities,
be deemed to be outstanding and to have been issued and sold by the Company for
such price per share. For the purposes of the preceding sentence, the "price per
share for which Common Stock

                                       29
<PAGE>

is issuable upon such conversion or exchange" shall be determined by dividing
(i) the total amount, if any, received or receivable by the Company as
consideration for the issuance or sale of all such Convertible Securities, plus
the minimum aggregate amount of additional consideration, if any, payable to the
Company upon the conversion or exchange thereof at the time such Convertible
Securities first become convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the conversion or exchange of all
such Convertible Securities. No further adjustment to the Exercise Price will be
made upon the actual issuance of such Common Stock upon conversion or exchange
of such Convertible Securities.

                  (iii) CHANGE IN OPTION PRICE OR CONVERSION RATE. If there is a
change at any time in (i) the amount of additional consideration payable to the
Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the conversion or exchange of
any Convertible Securities; or (iii) the rate at which any Convertible
Securities are convertible into or exchangeable for Common Stock (other than
under or by reason of provisions designed to protect against dilution), the
Exercise Price in effect at the time of such change will be readjusted to the
Exercise Price which would have been in effect at such time had such Options or
Convertible Securities still outstanding provided for such changed additional
consideration or changed conversion rate, as the case may be, at the time
initially granted, issued or sold.

                  (iv) TREATMENT OF EXPIRED OPTIONS AND UNEXERCISED CONVERTIBLE
SECURITIES. If, in any case, the total number of shares of Common Stock issuable
upon exercise of any Option or upon conversion or exchange of any Convertible
Securities is not, in fact, issued and the rights to exercise such Option or to
convert or exchange such Convertible Securities shall have expired or
terminated, the Exercise Price then in effect will be readjusted to the Exercise
Price which would have been in effect at the time of such expiration or
termination had such Option or Convertible Securities, to the extent outstanding
immediately prior to such expiration or termination (other than in respect of
the actual number of shares of Common Stock issued upon exercise or conversion
thereof), never been issued.

                  (v) CALCULATION OF CONSIDERATION RECEIVED. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting discounts or allowances or other reasonable expenses
paid or incurred by the Company in connection with such issuance, grant or sale.
In case any Common Stock, Options or Convertible Securities are issued or sold
for a consideration part or all of which shall be other than cash, the amount of
the consideration other than cash received by the Company will be the fair value
of such consideration, except where such consideration consists of securities,
in which case the amount of consideration received by the Company will be the
Market Price thereof as of the date of receipt. In case any Common Stock,
Options or Convertible Securities are issued in connection with any acquisition,
merger or consolidation in which the Company is the surviving corporation, the
amount of consideration therefor will be deemed to be the fair value of such
portion of the net assets and business of the non-surviving corporation as is
attributable to such Common Stock, Options or Convertible Securities, as the
case may be. The fair value of any consideration other than cash or securities
will be determined in good faith by the Board of Directors of the Company.

                                       30
<PAGE>

                  (vi) EXCEPTIONS TO ADJUSTMENT OF EXERCISE PRICE. No adjustment
to the Exercise Price will be made (i) upon the exercise of any warrants,
options or convertible securities granted, issued and outstanding on the date of
issuance of this Warrant; (ii) upon the grant or exercise of any stock or
options which may hereafter be granted or exercised under any employee benefit
plan of the Company now existing or to be implemented in the future, so long as
the issuance of such stock or options is approved by a majority of the
independent members of the Board of Directors of the Company or a majority of
the members of a committee of independent directors established for such
purpose; or (iii) upon the exercise of the Warrants.

                  (c) SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company
at any time subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) the shares of Common Stock
acquirable hereunder into a greater number of shares, then, after the date of
record for effecting such subdivision, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company at any
time combines (by reverse stock split, recapitalization, reorganization,
reclassification or otherwise) the shares of Common Stock acquirable hereunder
into a smaller number of shares, then, after the date of record for effecting
such combination, the Exercise Price in effect immediately prior to such
combination will be proportionately increased.

                  (d) ADJUSTMENT IN NUMBER OF SHARES. Upon each adjustment of
the Exercise Price pursuant to the provisions of this Paragraph 4, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable upon
exercise of this Warrant immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

                  (e) CONSOLIDATION, MERGER OR SALE. In case of any
consolidation of the Company with, or merger of the Company into any other
corporation, or in case of any sale or conveyance of all or substantially all of
the assets of the Company other than in connection with a plan of complete
liquidation of the Company, then as a condition of such consolidation, merger or
sale or conveyance, adequate provision will be made whereby the holder of this
Warrant will have the right to acquire and receive upon exercise of this Warrant
in lieu of the shares of Common Stock immediately theretofore acquirable upon
the exercise of this Warrant, such shares of stock, securities or assets as may
be issued or payable with respect to or in exchange for the number of shares of
Common Stock immediately theretofore acquirable and receivable upon exercise of
this Warrant had such consolidation, merger or sale or conveyance not taken
place. In any such case, the Company will make appropriate provision to insure
that the provisions of this Paragraph 4 hereof will thereafter be applicable as
nearly as may be in relation to any shares of stock or securities thereafter
deliverable upon the exercise of this Warrant. The Company will not effect any
consolidation, merger or sale or conveyance unless prior to the consummation
thereof, the successor or acquiring entity (if other than the Company) and, if
an entity different from the successor or acquiring entity, the entity whose
capital stock or assets the holders of the Common Stock of the Company are
entitled to receive as a result of such consolidation, merger or sale or
conveyance assumes by written instrument the obligations of the Company under
this Warrant (including under this Paragraph 4) and the obligations to deliver
to

                                       31
<PAGE>

the holder of this Warrant such shares of stock, securities or assets as, in
accordance with the foregoing provisions, the holder may be entitled to acquire.

                  (f) DISTRIBUTION OF ASSETS. In case the Company shall declare
or make any distribution of its assets (including cash) to holders of Common
Stock as a partial liquidating dividend, by way of return of capital or
otherwise, then, after the date of record for determining stockholders entitled
to such distribution, but prior to the date of distribution, the holder of this
Warrant shall be entitled upon exercise of this Warrant for the purchase of any
or all of the shares of Common Stock subject hereto, to receive the amount of
such assets which would have been payable to the holder had such holder been the
holder of such shares of Common Stock on the record date for the determination
of stockholders entitled to such distribution.

                  (g) NOTICE OF ADJUSTMENT. Upon the occurrence of any event
which requires any adjustment of the Exercise Price, then, and in each such
case, the Company shall give notice thereof to the holder of this Warrant, which
notice shall state the Exercise Price resulting from such adjustment and the
increase or decrease in the number of Warrant Shares purchasable at such price
upon exercise, setting forth in reasonable detail the method of calculation and
the facts upon which such calculation is based. Such calculation shall be
certified by the chief financial officer of the Company.

                  (h) MINIMUM ADJUSTMENT OF EXERCISE PRICE. No adjustment of the
Exercise Price shall be made in an amount of less than 1% of the Exercise Price
in effect at the time such adjustment is otherwise required to be made, but any
such lesser adjustment shall be carried forward and shall be made at the time
and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

                  (i) NO FRACTIONAL SHARES. No fractional shares of Common Stock
are to be issued upon the exercise of this Warrant, but the Company shall pay a
cash adjustment in respect of any fractional share which would otherwise be
issuable in an amount equal to the same fraction of the Market Price of a share
of Common Stock on the date of such exercise.

                  (j) OTHER NOTICES. In case at any time:

                                       32
<PAGE>

                           (i) the Company shall declare any dividend upon the
Common Stock payable in shares of stock of any class or make any other
distribution (including dividends or distributions payable in cash out of
retained earnings) to the holders of the Common Stock;

                           (ii) the Company shall offer for subscription pro
rata to the holders of the Common Stock any additional shares of stock of any
class or other rights;

                           (iii) there shall be any capital reorganization of
the Company, or reclassification of the Common Stock, or consolidation or merger
of the Company with or into, or sale of all or substantially all its assets to,
another corporation or entity; or

                           (iv) there shall be a voluntary or involuntary
dissolution, liquidation or winding-up of the Company; then, in each such case,
the Company shall give to the holder of this Warrant (a) notice of the date on
which the books of the Company shall close or a record shall be taken for
determining the holders of Common Stock entitled to receive any such dividend,
distribution, or subscription rights or for determining the holders of Common
Stock entitled to vote in respect of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up and (b) in
the case of any such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding-up, notice of the date (or, if not
then known, a reasonable approximation thereof by the Company) when the same
shall take place. Such notice shall also specify the date on which the holders
of Common Stock shall be entitled to receive such dividend, distribution, or
subscription rights or to exchange their Common Stock for stock or other
securities or property deliverable upon such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation, or winding-up, as the
case may be. Such notice shall be given at least 30 days prior to the record
date or the date on which the Company's books are closed in respect thereto.
Failure to give any such notice or any defect therein shall not affect the
validity of the proceedings referred to in clauses (i), (ii), (iii) and (iv)
above.

                  (k) CERTAIN EVENTS. If any event occurs of the type
contemplated by the adjustment provisions of this Paragraph 4 but not expressly
provided for by such provisions, the Company will give notice of such event as
provided in Paragraph 4(g) hereof, and the Company's Board of Directors will
make an appropriate adjustment in the Exercise Price and the number of shares of
Common Stock acquirable upon exercise of this Warrant so that the rights of the
Holder shall be neither enhanced nor diminished by such event.

                  (l) STOCKHOLDER RIGHTS PLAN; CERTAIN OPTIONS.

                           (i) Nothing contained herein or in the Securities
Purchase Agreement shall preclude the Board of Directors of the Company from
adopting a stockholder rights plan and the adoption of any such plan shall not
result in any adjustment to the Exercise Price or the number of Warrant Shares
issuable upon exercise of this Warrant; provided, however, if such plan is
adopted and any securities are issued thereunder that would require any
adjustment to the Exercise Price or the number of Warrant Shares, such
adjustment shall be made as and when required in accordance with the terms
hereof.

                                       33
<PAGE>

                           (ii) Notwithstanding anything to the contrary
contained in this Warrant, the grant by the Company of the options described in
Section 4(m) of the Securities Purchase Agreement shall not result in any
adjustment to the Exercise Price or the number of Warrant Shares issuable upon
exercise of this Warrant; provided, however, if any such options are exercised,
the Exercise Price and the number of Warrant Shares issuable upon the exercise
of this Warrant shall be adjusted in accordance with the terms hereof.

                  (m)      CERTAIN DEFINITIONS.

                           (i) "COMMON STOCK DEEMED OUTSTANDING" shall mean the
number of shares of Common Stock actually outstanding (not including shares of
Common Stock held in the treasury of the Company), plus (x) pursuant to
Paragraph 4(b)(i) hereof, the maximum total number of shares of Common Stock
issuable upon the exercise of Options, as of the date of such issuance or grant
of such Options, if any, and (y) pursuant to Paragraph 4(b)(ii) hereof, the
maximum total number of shares of Common Stock issuable upon conversion or
exchange of Convertible Securities, as of the date of issuance of such
Convertible Securities, if any.

                           (ii) "MARKET PRICE," as of any date, (i) means the
average of the last reported sale prices for the shares of Common Stock on the
Nasdaq Stock Market ("Nasdaq") for the five (5) trading days immediately
preceding such date as reported by Bloomberg Financial Markets or an equivalent
reliable reporting service mutually acceptable to and hereafter designated by
the holder of this Warrant and the Company ("Bloomberg"), or (ii) if Nasdaq is
not the principal trading market for the shares of Common Stock, the average of
the last reported sale prices on the principal trading market for the Common
Stock during the same period as reported by Bloomberg, or (iii) if market value
cannot be calculated as of such date on any of the foregoing bases, the Market
Price shall be the fair market value as reasonably determined in good faith by
(a) the Board of Directors of the Corporation or (b) at the option of a
majority-in-interest of the holders of the outstanding Warrants, by an
independent investment bank of nationally recognized standing in the valuation
of businesses similar to the business of the corporation. The manner of
determining the Market Price of the Common Stock set forth in the foregoing
definition shall apply with respect to any other security in respect of which a

Paragraph 4, includes the Common Stock, par value $.005 per share, and any
additional class of stock of the Company having no preference as to dividends or
distributions on liquidation, provided that the shares purchasable pursuant to

         5. ISSUE TAX. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

         6. NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a shareholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

         7. TRANSFER, EXCHANGE, AND REPLACEMENT OF WARRANT.

                  (a) RESTRICTION ON TRANSFER. This Warrant and the rights
granted to the holder hereof are transferable, in whole or in part, upon
surrender of this Warrant, together with a properly executed assignment in the
form attached hereto, at the office or agency of the Company referred to in
Paragraph 7(e) below; provided, however, that any transfer or assignment shall
be subject to the conditions set forth in Paragraph 7(f) hereof and to the
applicable provisions of the Securities Purchase Agreement. Until due
presentment for registration of transfer on the books of the Company, the
Company may treat the registered holder hereof as the owner and holder hereof
for all purposes, and the Company shall not be affected by any notice to the
contrary. Notwithstanding anything to the contrary contained herein, the
registration rights described in Paragraph 8 are assignable only in accordance
with the provisions of that certain Registration Rights Agreement, dated as of
February 24, 2000, by and among the Company and the other signatories thereto
(the "Registration Rights Agreement").

                  (b) WARRANT EXCHANGEABLE FOR DIFFERENT DENOMINATIONS. This
Warrant is exchangeable, upon the surrender hereof by the holder hereof at the
office or agency of the Company referred to in Paragraph 7(e) below, for new
Warrants of like tenor representing in the aggregate the right to purchase the
number of shares of Common Stock which may be purchased hereunder, each of such
new Warrants to represent the right to purchase such number of shares as shall
be designated by the holder hereof at the time of such surrender.

                  (c) REPLACEMENT OF WARRANT. Upon receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction, or
mutilation of this Warrant and, in the case of any such loss, theft, or
destruction, upon delivery of an indemnity agreement reasonably satisfactory in
form and amount to the Company, or, in the case of any such mutilation, upon
surrender and cancellation of this Warrant, the Company, at its expense, will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

                  (d) CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of
this Warrant in connection with any transfer, exchange, or replacement as
provided in this Paragraph 7, this Warrant shall be promptly canceled by the
Company. The Company shall pay all taxes

                                       35

the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.

                  (f) EXERCISE OR TRANSFER WITHOUT REGISTRATION. If, at the time
of the surrender of this Warrant in connection with any exercise, transfer, or
exchange of this Warrant, this Warrant (or, in the case of any exercise, the
Warrant Shares issuable hereunder), shall not be registered under the Securities
Act and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such exercise, transfer, or exchange, (i)
that the holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel, which opinion and counsel are
acceptable to the Company, to the effect that such exercise, transfer, or
exchange may be made without registration under said Act and under applicable
state securities or blue sky laws, (ii) that the holder or transferee execute
and deliver to the Company an investment letter in form and substance acceptable
to the Company and (iii) that the transferee be an "accredited investor" as
defined in Rule 501(a) promulgated under the Securities Act; provided that no
such opinion, letter or status as an "accredited investor" shall be required in
connection with a transfer pursuant to Rule 144 under the Securities Act.

         8. REGISTRATION RIGHTS. The initial holder of this Warrant (and certain
assignees thereof) is entitled to the benefit of such registration rights in
respect of the Warrant Shares as are set forth in Section 2 of the Registration
Rights Agreement.

                  (a) AMENDMENTS.  This Warrant and any provision hereof may
only be amended by an instrument in writing signed by the Company and the holder
hereof.

                  (b) DESCRIPTIVE HEADINGS. The descriptive headings of the
several paragraphs of this Warrant are inserted for purposes of reference only,
and shall not affect the meaning or construction of any of the provisions
hereof.

                  (c) CASHLESS EXERCISE. Notwithstanding anything to the
contrary contained in this Warrant, if the resale of the Warrant Shares by the

under the Securities Act, this Warrant may be exercised by presentation and
surrender of this Warrant to the Company at its principal executive offices with
a written notice of the holder's intention to effect a cashless exercise,
including a calculation of the number of shares of Common Stock to be issued
upon such exercise in accordance with the terms hereof (a "Cashless Exercise").
In the event of a Cashless Exercise, in lieu of paying the Exercise Price in
cash, the holder shall surrender this Warrant for that number of shares of
Common Stock determined by multiplying the number of Warrant Shares to which it
would otherwise be entitled by a fraction, the numerator of which shall be the
difference between the then current Market Price per share of the Common Stock
and the Exercise Price, and the denominator of which shall be the then current
Market Price per share of Common Stock.

Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Warrant will be inadequate and agrees, in the event of a
breach or threatened breach by the Company of the provisions hereunder, that the
holder shall be entitled, in addition to all other available remedies at law or
in equity, to an injunction or injunctions restraining, preventing or curing any
breach of this Warrant and to enforce specifically the terms and provisions
hereof, without the necessity of showing economic loss and without any bond or
other security being required.

                          REGISTRATION RIGHTS AGREEMENT

         REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT"), dated as of February
24, 2000, by and among Biospherics Incorporated, a Delaware corporation, with
its headquarters located at 12051 Indian Creek Court, Beltsville, MD 20705 (the
"COMPANY"), and each of the undersigned (together with their respective
affiliates and any assignee or transferee of all of their respective rights
hereunder, the "INITIAL INVESTORS").

                                    WHEREAS:

         A. In connection with the Securities Purchase Agreement by and among
the parties hereto of even date herewith (the "SECURITIES PURCHASE AGREEMENT"),
the Company has agreed, upon the terms and subject to the conditions contained
therein, to issue and sell to the Initial Investors 723,982 units (the "Units"),
each Unit consisting of (i) one share of the Company's common stock, par value
$.005 per share (the "COMMON STOCK"); and (ii) one and one-half (1.5) warrants
(the "WARRANTS"), each Warrant to acquire one (1) share of Common Stock, upon
the terms and conditions and subject to the limitations and conditions set forth
in the Warrants dated February 24, 2000; and

         B. To induce the Initial Investors to execute and deliver the
Securities Purchase Agreement, the Company has agreed to provide certain
registration rights under the Securities Act of 1933, as amended, and the rules
and regulations thereunder, or any similar successor statute (collectively, the
"1933 ACT"), and applicable state securities laws;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and each
of the Initial Investors hereby agree as follows:

<PAGE>

         1. DEFINITIONS.

                  a. As used in this Agreement, the following terms shall have
the following meanings:

                           (i) "INVESTORS" means the Initial Investors and any
transferee or assignee who agrees to become bound by the provisions of this
Agreement in accordance with Section 9 hereof.

                           (ii) "REGISTER," "REGISTERED," and "REGISTRATION"
refer to a registration effected by preparing and filing a Registration
Statement or Statements in compliance with the 1933 Act and pursuant to Rule 415
under the 1933 Act or any successor rule providing for offering securities on a
continuous basis ("RULE 415"), and the declaration or ordering of effectiveness
of such Registration Statement by the United States Securities and Exchange
Commission (the "SEC").

                           (iii) "REGISTRABLE SECURITIES" means (a) the Common
Shares issued pursuant to the Securities Purchase Agreement, (b) the Warrant
Shares issued or issuable upon exercise of or otherwise pursuant to the Warrants
issued pursuant to the Securities Purchase Agreement and (c) any shares of
capital stock issued or issuable as a dividend on or in exchange for or
otherwise with respect to any of the foregoing.

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

                  b. Capitalized terms used herein and not otherwise defined
herein shall have the respective meanings set forth in the Securities Purchase
Agreement.

         2. REGISTRATION.

                  a. MANDATORY REGISTRATION. The Company shall prepare, and, on
or prior to the date (the "FILING DATE") which is twenty (20) days after the
date of the Closing under the Securities Purchase Agreement (the "CLOSING
DATE"), file with the SEC a Registration Statement on Form S-3 (or, if Form S-3
is not then available, on such form of Registration Statement as is then
available to effect a registration of the Registrable Securities, subject to the
consent of the Initial Investors, which consent will not be unreasonably
withheld) and pursuant to Rule 415 covering the resale from time to time by the
holders thereof of the Registrable Securities, which Registration Statement, to
the extent allowable under the 1933 Act and the rules and regulations
promulgated thereunder (including Rule 416), shall state that such Registration
Statement also covers such indeterminate number of additional shares of Common
Stock as may become issuable upon exercise of or otherwise pursuant to the
Warrants (i) to prevent dilution resulting from stock splits, stock dividends or
similar transactions or (ii) by reason of changes in the exercise price of the
Warrants in accordance with the terms thereof. The number of shares of Common
Stock initially included in such Registration Statement shall be no less than
the sum of

                                       43
<PAGE>

(x) the number of Common Shares issued pursuant to the Securities Purchase
Agreement and (y) one hundred (100%) of the aggregate number of Warrant Shares
that are then issuable upon exercise of or otherwise pursuant to the Warrants,
without regard to any limitation on the Investors' ability to exercise the
Warrants. The Company acknowledges that the number of Warrant Shares initially
included in the Registration Statement represents a good faith estimate of the
maximum number of shares issuable upon exercise of or otherwise pursuant to the
Warrants. The Registration Statement (and each amendment or supplement thereto,
and each request for acceleration of effectiveness thereof) shall be provided to
(and subject to the approval of) the Initial Investors and their counsel prior
to its filing or other submission.

                  b. [Intentionally Omitted].

                  c. PAYMENTS BY THE COMPANY. The Company shall use its best
efforts to obtain effectiveness of the Registration Statement as soon as
practicable, but in any event not later than one hundred twenty (120) days after
the Closing Date (the "REGISTRATION DEADLINE"). If (i) the Registration
Statement covering the Registrable Securities required to be filed by the
Company pursuant to Section 2(a) hereof is not declared effective by the SEC by
the Registration Deadline, or (ii) after the Registration Statement has been
declared effective by the SEC, sales of all of the Registrable Securities cannot
be made pursuant to the Registration Statement, or (iii) the Common Stock is not
listed or included for quotation on the Nasdaq National Market ("NASDAQ"), the
Nasdaq SmallCap Market ("NASDAQ SMALLCAP"), the New York Stock Exchange (the
"NYSE") or the American Stock Exchange (the "AMEX") after being so listed or
included for quotation, then the Company will make payments to the Investors in
such amounts and at such times as shall be determined pursuant to this Section
2(c) as partial relief for the damages to the Investors by reason of any such
delay in or reduction of their ability to sell the Registrable Securities (which
remedy shall not be exclusive of any other remedies available at law or in
equity). The Company shall pay to each holder of Registrable Securities an
amount equal to (x) the aggregate purchase price paid by such holder pursuant to
the Securities Purchase Agreement (or upon exercise of the Warrants) for the
Common Shares and Warrant Shares held by such holder at the time of an event
specified in clause (i), (ii) or (iii) above (the "AGGREGATE PURCHASE PRICE"),
multiplied by (y) the Applicable Percentage (as defined below), multiplied by
(z) the sum of: (i) the number of months (prorated for partial months) after the
end of the Registration Deadline and prior to the date the Registration
Statement is declared effective by the SEC; PROVIDED, HOWEVER, that there shall
be excluded from such period any delays which are solely attributable to (A)
changes required by the Investors in the Registration Statement with respect to
information relating to the Investors, including, without limitation, changes to
the plan of distribution, (B) the failure of the Investors to conduct their
review of the Registration Statement pursuant to Section 3(h) below in a
reasonably prompt manner or (C) any objection to such Registration Statement
being declared effective by the SEC based primarily on the structure of the
transactions contemplated by the Securities Purchase Agreement; (ii) the number
of months (prorated for partial months) during the Registration Period (as
defined below) that sales of all of the Registrable Securities cannot be made
pursuant to the Registration Statement after the Registration Statement has been
declared effective (including, without limitation, when sales cannot be made by
reason of the Company's failure to properly supplement or amend the prospectus
included therein in accordance with the terms of this Agreement (including
Section

                                       44
<PAGE>

3(b) hereof or otherwise), but excluding any days during an Allowed Delay (as
defined in Section 3(f)); and (iii) the number of months (prorated for partial
months) that the Common Stock is not listed or included for quotation on the
Nasdaq, Nasdaq SmallCap, NYSE or AMEX or that trading thereon is halted after
the Registration Statement has been declared effective. The term "APPLICABLE
PERCENTAGE" means two hundredths (.02). (For example, if the Registration
Statement becomes effective one (1) month after the Registration Deadline, the
Company would pay $20,000 for each $1,000,000 of Aggregate Purchase Price. If
thereafter, sales of all of the Registrable Securities could not be made
pursuant to the Registration Statement for an additional period of one (1)
month, the Company would pay an additional $20,000 for each $1,000,000 of
Aggregate Purchase Price.) Such amounts shall be paid in cash or, at each
Investor's option, in shares of Common Stock valued at the closing bid price of
such shares on the trading day immediately preceding the date of payment. Any
shares of Common Stock delivered pursuant to this Section 2(c) shall be
Registrable Securities. If the Investor desires to receive the amounts due
hereunder in shares of Common Stock, it shall so notify the Company in writing
within two (2) business days of the date on which such amounts are first payable
in cash. Payments of cash pursuant hereto shall be made within five (5) days
after the end of each period that gives rise to such obligation, provided that,
if any such period extends for more than thirty (30) days, interim payments
shall be made for each such thirty (30) day period.

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

                                       45
<PAGE>

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

                  e. ELIGIBILITY FOR FORM S-3. The Company represents and
warrants that it meets the registrant eligibility and transaction requirements
for the use of Form S-3 for registration of the sale by the Initial Investors
and any other Investors of the Registrable Securities and the Company shall file
all reports required to be filed by the Company with the SEC in a timely manner
so as to maintain such eligibility for the use of Form S-3.

         3. OBLIGATIONS OF THE COMPANY.

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

                  a. The Company shall prepare promptly, and file with the SEC
as soon as practicable after the Closing Date (but no later than the Filing
Date), a Registration Statement with respect to the number of Registrable
Securities provided in Section 2(a), and thereafter use its best efforts to
cause such Registration Statement relating to Registrable Securities to become
effective as soon as possible after such filing (but in no event later than the
Registration Deadline), and keep the Registration Statement effective pursuant
to Rule 415 at all times until such date as is the earlier of (i) the date on
which all of the Registrable Securities have been sold and (ii) the date on
which the Registrable Securities (in the opinion of counsel to the Initial
Investors) may be immediately sold to the public without registration or
restriction (including without limitation as to volume by each holder thereof)
under the 1933 Act (including under Rule 144(k)) (the "REGISTRATION PERIOD"),
which Registration Statement (including any amendments or supplements thereto
and prospectuses contained therein) shall not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein, or
necessary to make the statements therein not misleading.

                  b. The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) and supplements to the
Registration Statements and the prospectus used in connection with the
Registration Statements as may be necessary to keep the Registration Statements
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act with respect to the disposition of
all

                                       46
<PAGE>

Registrable Securities of the Company covered by the Registration Statements
until such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in the Registration Statements. In the event that on any
date (the "REGISTRATION TRIGGER DATE") the number of shares available under a
Registration Statement filed pursuant to this Agreement is insufficient to cover
all of the Registrable Securities (based on the number of Common Shares then
held by Investors and the number of Warrant Shares issued or issuable upon
exercise of or otherwise pursuant to the Warrants, without giving effect to any
limitations on the Investors' ability to exercise the Warrants), the Company
shall amend the Registration Statement, or file a new Registration Statement (on
the short form available therefor, if applicable), or both, so as to cover all
of the Registrable Securities so issued or issuable (without giving effect to
any limitations on exercise contained in the Warrants) as of the Registration
Trigger Date, in each case, as soon as practicable, but in any event within
twenty (20) business days after the necessity therefor arises (based on the
market price of the Common Stock and other relevant factors on which the Company
reasonably elects to rely). The Company shall use its best efforts to cause such
amendment and/or new Registration Statement to become effective as soon as
practicable following the filing thereof, but in any event within sixty (60)
days of the Registration Trigger Date. The provisions of Section 2(c) above
shall be applicable with respect to the Company's obligations under this Section
3(b).

                  c. The Company shall furnish to each Investor whose
Registrable Securities are included in a Registration Statement and its legal
counsel (i) promptly after the same is prepared and publicly distributed, filed
with the SEC, or received by the Company, one copy of each Registration
Statement and any amendment thereto, each preliminary prospectus and prospectus
and each amendment or supplement thereto, and, in the case of the Registration
Statement referred to in Section 2(a), each letter written by or on behalf of
the Company to the SEC or the staff of the SEC, and each item of correspondence
from the SEC or the staff of the SEC, in each case relating to such Registration
Statement (other than any portion of any thereof which contains information for
which the Company has sought confidential treatment), and (ii) such number of
copies of a prospectus, including a preliminary prospectus, and all amendments
and supplements thereto and such other documents as such Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such Investor. The Company will immediately notify each Investor by
facsimile of the effectiveness of each Registration Statement or any
post-effective amendment. The Company will promptly respond to any and all
comments received from the SEC, with a view towards causing each Registration
Statement or any amendment thereto to be declared effective by the SEC as soon
as practicable and shall file an acceleration request as soon as practicable
following the resolution or clearance of all SEC comments or, if applicable,
following notification by the SEC that any such Registration Statement or any
amendment thereto will not be subject to review.

                  d. The Company shall use its best efforts to (i) register and
qualify the Registrable Securities covered by the Registration Statements under
such other securities or "blue sky" laws of such jurisdictions in the United
States as the Investors who hold a majority in interest of the Registrable
Securities being offered reasonably request, (ii) prepare and file in those
jurisdictions such amendments (including post-effective amendments) and
supplements to

                                       47
<PAGE>

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

                  e. [Intentionally Omitted].

                  f. As promptly as practicable after becoming aware of such
event, the Company shall notify each Investor of the happening of any event, as
a result of which the prospectus included in any Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and use its best efforts promptly to prepare and file
with SEC a supplement or amendment to such Registration Statement to correct
such untrue statement or omission, and deliver such number of copies of such
supplement or amendment to each Investor as such Investor may reasonably
request; provided that, for not more than 10 consecutive days or for a total of
not more than 30 days during any one-year period, the Company may delay the
filing of such supplement, amendment or other document or other public
disclosure of the material non-public information concerning the Company, the
disclosure of which at the time is not, in the good faith opinion of the Board
of Directors of the Company, in the best interests of the Company and, in the
opinion of counsel to the Company, otherwise required (an "Allowed Delay"); and
provided, further, that the Company shall promptly (i) notify the Investors in
writing of the existence of (but in no event, without the prior written consent
of an Investor, shall the Company disclose to such Investor any of the facts or
circumstances regarding) material non-public information giving rise to an
Allowed Delay and (ii) advise the Investors in writing to cease all sales under
such Registration Statement until the end of the Allowed Delay. Upon expiration
of the Allowed Delay, the Company shall again be bound by the first sentence of
this Section 3(c) with respect to the information giving rise thereto.

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

                  h. The Company shall permit a single firm of counsel
designated by the Initial Investors to review such Registration Statement and
all amendments and supplements thereto (as well as all requests for acceleration
or effectiveness thereof) a reasonable period of time prior to their filing with
the SEC, and not file any document in a form to which such

                                       48
<PAGE>

counsel reasonably objects and will not request acceleration of such
Registration Statement without prior notice to such counsel. The Initial
Investors shall cause such counsel to respond promptly to all documents
submitted for such counsel's review. The sections of such Registration Statement
covering information with respect to the Investors, the Investor's beneficial
ownership of securities of the Company or the Investors intended method of
disposition of Registrable Securities shall conform to the information provided
to the Company by each of the Investors.

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

                  j. [Intentionally Omitted]

                  k. The Company shall make available for inspection by (i) any
Investor, (ii) any underwriter participating in any disposition pursuant to a
Registration Statement, (iii) one firm of attorneys and one firm of accountants
or other agents retained by the Initial Investors, (iv) one firm of attorneys
and one firm of accountants or other agents retained by all other Investors, and
(v) one firm of attorneys retained by all such underwriters (collectively, the
"INSPECTORS") all pertinent financial and other records, and pertinent corporate
documents and properties of the Company (collectively, the "RECORDS"), as shall
be reasonably deemed necessary by each Inspector to enable each Inspector to
exercise its due diligence responsibility, and cause the Company's officers,
directors and employees to supply all information which any Inspector may
reasonably request for purposes of such due diligence; PROVIDED, HOWEVER, that
each Inspector shall hold in confidence and shall not make any disclosure
(except to an Investor) of any Record or other information which the Company
determines in good faith to be confidential, and of which determination the
Inspectors are so notified, unless (a) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement, (b) the release of such Records is ordered pursuant to a subpoena or
other order from a court or government body of competent jurisdiction, or (c)
the information in such Records has been made generally available to the public
other than by disclosure in violation of this or any other agreement. The
Company shall not be required to disclose any confidential information in such
Records to any Inspector until and unless such Inspector shall have entered into
confidentiality agreements (in form and substance satisfactory to the Company)
with the Company with respect thereto, substantially in the form of this Section
3(k). Each Investor agrees that it shall, upon learning that disclosure of such
Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, the Records deemed
confidential. Nothing herein (or in any other confidentiality agreement between
the Company and any Investor) shall be deemed to limit the Investors' ability to
sell Registrable Securities in a manner which is otherwise consistent with
applicable laws and regulations.

                                       49
<PAGE>

                  l. The Company shall hold in confidence and not make any
disclosure of information concerning an Investor provided to the Company unless
(i) disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other order
from a court or governmental body of competent jurisdiction, or (iv) such
information has been made generally available to the public other than by
disclosure in violation of this or any other agreement. The Company agrees that
it shall, upon learning that disclosure of such information concerning an
Investor is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to such Investor prior
to making such disclosure, and allow the Investor, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, such information.

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

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

                  o. The Company shall cooperate with the Investors who hold
Registrable Securities being offered and the managing underwriter or
underwriters, if any, to facilitate the timely preparation and delivery of
certificates (not bearing any restrictive legends) representing Registrable
Securities to be offered pursuant to such Registration Statement and enable such
certificates to be in such denominations or amounts, as the case may be, as the
managing underwriter or underwriters, if any, or the Investors may reasonably
request and registered in such names as the managing underwriter or
underwriters, if any, or the Investors may request, and, within three (3)
business days after a Registration Statement which includes Registrable
Securities is ordered effective by the SEC, the Company shall deliver, and shall
cause legal counsel selected by the Company to deliver, to the transfer agent
for the Registrable Securities (with copies to the Investors whose Registrable
Securities are included in such Registration Statement) an instruction in the
form attached hereto as EXHIBIT 1 and an opinion of such counsel in the form
attached hereto as EXHIBIT 2.

                  p. At the request of any Investor, the Company shall prepare
and file with the SEC such amendments (including post-effective amendments) and
supplements to a Registration

                                       50
<PAGE>

Statement and any prospectus used in connection with the Registration Statement
as may be necessary in order to change the plan of distribution set forth in
such Registration Statement.

                  q. The Company shall not, and shall not agree to, allow the
holders of any securities of the Company to include any of their securities in
any Registration Statement under Section 2(a) hereof or any amendment or
supplement thereto under Section 3(b) hereof without the consent of the holders
of a majority-in-interest of the Registrable Securities. In addition, the
Company shall not offer any securities for its own account or the account of
others in any Registration Statement under Section 2(a) hereof or any amendment
or supplement thereto under Section 3(b) hereof without the consent of the
holders of a majority-in-interest of the Registrable Securities.

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

                  s. The Company shall comply with all applicable laws related
to a Registration Statement and offering and sale of securities and all
applicable rules and regulations of governmental authorities in connection
therewith (including without limitation the 1933 Act and the 1934 Act and the
rules and regulations promulgated by the SEC).

         4. OBLIGATIONS OF THE INVESTORS.

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

                  a. It shall be a condition precedent to the obligations of the
Company to complete the registration pursuant to this Agreement with respect to
the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the registration
of such Registrable Securities and shall execute such documents in connection
with such registration as the Company may reasonably request. At least five (5)
business days prior to the first anticipated filing date of the Registration
Statement, the Company shall notify each Investor of the information the Company
requires from each such Investor.

                  b. Each Investor, by such Investor's acceptance of the
Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the
Registration Statements hereunder, unless such Investor has notified the Company
in writing of such Investor's election to exclude all of such Investor's
Registrable Securities from the Registration Statements.

                  c. [Intentionally Omitted]

                                       51
<PAGE>

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

                  e. No Investor may participate in any underwritten
registration hereunder unless such Investor (i) agrees to sell such Investor's
Registrable Securities on the basis provided in any underwriting arrangements in
usual and customary form entered into by the Company, (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements, and (iii) agrees to pay its pro rata share of all
underwriting discounts and commissions and any expenses in excess of those
payable by the Company pursuant to Section 5 below.

         5. EXPENSES OF REGISTRATION.

         All reasonable expenses, other than underwriting discounts and
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualification fees, printers and accounting fees, the
fees and disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel selected by the Initial Investors pursuant to
Sections 2(b) and 3(h) hereof shall be borne by the Company; provided, however,
so long as the Company has paid to the Initial Investors the amount required by
Section 4(f) of the Securities Purchase Agreement, no further payment for the
fees and disbursements of such counsel pursuant to this Section 5 shall be
required.

         6. INDEMNIFICATION.

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

                  a. To the extent permitted by law, the Company will indemnify,
hold harmless and defend (i) each Investor who holds such Registrable
Securities, (ii) the directors, officers, partners, employees, agents and each
person who controls any Investor within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 ACT"), if any, (iii) any
underwriter (as defined in the 1933 Act) participating in any disposition of
Registrable Securities and (iv) the directors, officers, partners, employees and
each person who controls any such underwriter within the meaning of the 1933 Act
or the 1934 Act, if any (each,

                                       52
<PAGE>

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

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

                                       53
<PAGE>

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

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

                                       54
<PAGE>

Section 6 shall be made by periodic payments of the amount thereof during
the course of the investigation or defense, as such expense, loss, damage or
liability is incurred and is due and payable.

         7. CONTRIBUTION.

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

         8. REPORTS UNDER THE 1934 ACT.

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

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

                  b. file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents is required for the applicable provisions of Rule 144; and

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

         9. ASSIGNMENT OF REGISTRATION RIGHTS.

                                       55
<PAGE>

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

         10. AMENDMENT OF REGISTRATION RIGHTS.

         Provisions of this Agreement may be amended and the observance thereof
may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with written consent of the Company, each
of the Initial Investors (to the extent such Initial Investor still owns
Warrants or Registrable Securities) and Investors who hold a
majority-in-interest of the remaining Registrable Securities or, in the case of
a waiver, with the written consent of the party charged with the enforcement of
any such provision. Any amendment or waiver effected in accordance with this
Section 10 shall be binding upon each Investor and the Company.

         11. MISCELLANEOUS.

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

                  b. Any notices required or permitted to be given under the
terms hereof shall be sent by certified or registered mail (return receipt
requested) or delivered personally or by courier (including a recognized
overnight delivery service) or by facsimile and shall be effective five days
after being placed in the mail, if mailed by regular United States mail, or upon
receipt, if delivered personally or by courier (including a recognized overnight
delivery service) or by facsimile, in each case addressed to a party. The
addresses for such communications shall be:

                           Facsimile: (215) 568-6603

                  c. Failure of any party to exercise any right or remedy under
this Agreement or otherwise, or delay by a party in exercising such right or
remedy, shall not operate as a waiver thereof.

                  d. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to agreements made
and to be performed in the State of Delaware (without regard to principles of
conflict of laws). Both parties irrevocably consent to the jurisdiction of the
United States federal courts and the state courts located in Delaware with
respect to any suit or proceeding based on or arising under this Agreement, the
agreements entered into in connection herewith or the transactions contemplated
hereby or thereby and irrevocably agree that all claims in respect of such suit
or proceeding may be determined in such courts. Both parties irrevocably waive
the defense of an inconvenient forum to the maintenance of such suit or
proceeding. Both parties further agree that service of process upon a party
mailed by first class mail shall be deemed in every respect effective service of
process upon the party in any such suit or proceeding. Nothing herein shall
affect either party's right to serve process in any other manner permitted by
law. Both parties agree that a final non-appealable judgment in

                                       57
<PAGE>

any such suit or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on such judgment or in any other lawful manner.

                  e. This Agreement, the Securities Purchase Agreement, and the
Warrants (including all schedules and exhibits thereto) constitute the entire
agreement among the parties hereto with respect to the subject matter hereof and
thereof. There are no restrictions, promises, warranties or undertakings, other
than those set forth or referred to herein and therein. This Agreement, the
Securities Purchase Agreement and the Warrants supersede all prior agreements
and understandings among the parties hereto with respect to the subject matter
hereof and thereof.

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

                  g. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

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

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

                  j. Except as otherwise provided herein, all consents and other
determinations to be made by the Investors pursuant to this Agreement shall be
made by Investors holding a majority-in-interest of the Registrable Securities,
determined as if the all of the Warrants then outstanding have been exercised
for Registrable Securities.

                  k. The Company acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to each Investor by vitiating
the intent and purpose of the transactions contemplated hereby. Accordingly, the
Company acknowledges that the remedy at law for breach of its obligations
hereunder will be inadequate and agrees, in the event of a breach or threatened
breach by the Company of any of the provisions hereunder, that each Investor
shall be entitled, in addition to all other available remedies in law or in
equity, to an injunction or injunctions to prevent or cure breaches of the
provisions of this Agreement and to enforce specifically the terms and
provisions hereof, without the necessity of showing economic loss and without
any bond or other security being required.

                                       58

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

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

                  n. The initial number of Registrable Securities included in
any Registration Statement and each increase to the number of Registrable
Securities included therein shall be allocated pro rata among the Investors
based on the number of Registrable Securities held by each Investor at the time
of such establishment or increase, as the case may be. In the event an Investor
shall sell or otherwise transfer any of such holder's Registrable Securities,
each transferee shall be allocated a pro rata portion of the number of
Registrable Securities included in a Registration Statement for such transferor.
Any shares of Common Stock included in a Registration Statement and which remain
allocated to any person or entity which does not hold any Registrable Securities
shall be allocated to the remaining Investors, pro rata based on the number of
shares of Registrable Securities then held by such Investors. For the avoidance
of doubt, the number of Registrable Securities held by an Investor shall be
determined as if all the Warrants then outstanding and held by an Investor were
exercised for Registrable Securities.

Investors have caused this Agreement to be duly executed as of the date first
