                          CHANGE IN CONTROL AGREEMENT

         CHANGE IN CONTROL AGREEMENT (this "Agreement") entered into as of
January 7, 2003, by and between J. Paul Quinn (the "Executive") and N2H2, Inc.,
a Washington corporation (the "Company").

                                    RECITALS

         A. The Executive was hired by the Company on or about November 2000,
and now serves as the Company's CFO.

         B. The Board of Directors of the Company (the "Board") recognizes that
the possibility of a Change in Control (as defined below) exists and that the
threat or the occurrence of a Change in Control can result in significant
distractions to its key personnel because of the uncertainties inherent in such
a situation.

         C. The Board has determined that it is in the best interests of the
Company and its shareholders to retain the services of the Executive in the
event of a threat or occurrence of a Change in Control and to ensure the
Executive's continued dedication and efforts in such event without undue concern
for the Executive's personal, financial and employment security.

         D. In order to induce the Executive to continue employment with the
Company, as well as to remain with the Company in the event of a threat or
occurrence of a Change in Control, the Company desires to enter into this
Agreement with the Executive to provide the Executive with certain benefits in
the event that the Executive's employment is terminated as a result of, or in
connection with, an impending or actual Change in Control.

                                    AGREEMENT

the Notice of Termination shall be at least fifteen (15) days from the date the
Notice of Termination is given to the Executive.

2. Effective Date and Term of Agreement. This Agreement is effective on the date
hereof and shall continue in effect until the Company shall have given one (1)
year's written notice of cancellation; provided, however, that notwithstanding
the delivery of any such notice, this Agreement shall continue in effect for a
period of nine (9) months after a Change in Control, if such Change in Control
shall have occurred during the term of this Agreement. Except as provided in
Section 3, this Agreement shall terminate if the Executive or the Company
terminates the Executive's employment prior to a Change in Control.

3. Termination of Employment.

         (a) If, during the term of this Agreement, the Executive's employment
with the Company shall be terminated within nine (9) months following a Change
in Control, the Executive shall be entitled to the following compensation and
benefits:

                  (i) If the Executive's employment with the Company shall be
terminated (A) by the Company for Cause or Disability, (B) by reason of the
Executive's death or (C) by the Executive other than for Good Reason, the
Company shall pay to the Executive the Accrued Compensation.

                  (ii) If the Executive's employment with the Company shall be
terminated for any reason other than as specified in Section 3(a)(i), the
Executive shall be entitled to the following:

                        (1) the Company shall pay the Executive all Accrued
Compensation;

                                      -3-
<PAGE>
                        (2) the Company shall pay the Executive as severance pay
and in lieu of any further compensation for periods subsequent to the
Termination Date, in a single payment, an amount in cash equal to nine twelfths
(9/12) of the Base Compensation; and

                        (3) for a period of nine (9) months after the
Termination Date (the "Continuation Period"), the Company shall, at its expense,
continue on behalf of the Executive and the Executive's dependents and
beneficiaries the [life insurance, disability, medical, dental and
hospitalization] benefits provided (A) to the Executive at any time during the
ninety (90) day period prior to the Change in Control or at any time thereafter
or (B) to other similarly situated employees who continue in the employ of the
Company during the Continuation Period. The coverage and benefits (including
deductibles and costs) provided in this Section 3(a)(ii)(3) during the
Continuation Period shall be no less favorable to the Executive and his or her
dependents and beneficiaries than the most favorable of such coverages and
benefits during any of the periods referred to in clauses (A) and (B) above. The
Company's obligation hereunder with respect to the foregoing benefits shall be
limited to the extent that the Executive obtains any such benefits pursuant to a
subsequent employer's benefit plans, in which case the Company may reduce the
coverage of any benefits it is required to provide the Executive hereunder as
long as the aggregate coverages and benefits of the combined benefit plans are
no less favorable to the Executive than the coverages and benefits required to
be provided hereunder. This subsection (3) shall not be interpreted so as to
limit any benefits to which the Executive or his or her dependents or
beneficiaries may be entitled under any of the Company's benefit plans, programs
or practices following the Executive's termination of employment, including,
without limitation, retiree, medical and life insurance benefits.

         (b) If, during the term of this Agreement, the Executive's employment
with the Company shall be terminated in connection with an impending Change in
Control for any reason other than the reasons specified in Section 3(a)(i), the
Executive shall be entitled to the compensation and benefits described in
Section 3(a)(ii) above. The Board shall determine in good faith whether such a
termination or resignation is occurring in connection with an impending Change
in Control. However, such a termination shall in any event be deemed to be in
connection with an impending Change in Control if such termination or
resignation (i) is required by the definitive merger agreement or other
instrument relating to such Change in Control or (ii) is made at the express
request of the other party to the transaction constituting such Change in
Control.

         (c) The amounts provided for in Section 3(a) shall be paid in a
lump-sum cash payment not more than fifteen (15) business days following the
Executive's Termination Date (or earlier, if required by applicable law).

         (d) The severance pay and benefits provided for in this Section 3 shall
be in lieu of any other post termination of employment payments to which the
Executive may be entitled under any Company severance or termination plan,
program, practice or arrangement.

         (e) Notwithstanding Section 3(d), or anything to the contrary herein,
nothing in this Agreement shall be construed to modify or amend the terms of any
stock option grant made to the Executive, the terms of which shall continue to
be governed by the applicable stock option

                                      -4-
<PAGE>
letter agreement between the Executive and the Company and the applicable stock
option plan under which such stock option was granted.

         (f) The Executive shall not be required to mitigate the amount of any
payment contemplated by this Section 3 (whether by seeking new employment or in
any other manner). No such payment shall be reduced by earnings that the
Executive may receive from any other source.

         (g) The Executive's right to the severance payments under this
Agreement shall be conditioned upon the Executive's execution and delivery of a
release agreement in a form satisfactory to the Company, that is not revoked by
the Executive.

4.       Notice of Termination

         Within twelve (12) months following a Change in Control, any purported
termination of the Executive's employment shall be communicated by a Notice of
Termination to the Executive. For purposes of this Agreement, no such purported
termination shall be effective without such Notice of Termination.

5.       Tax Effect of Payments.

         (a) Tax Restoration Payment. In the event that it is determined that
any payment or distribution of any type to or for the benefit of the Executive
made by the Company, by any of its affiliates, by any person who acquires
ownership or effective control of the Company or ownership of a substantial
portion of the Company's assets (within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended, and the regulations thereunder (the
"Code")) or by any affiliate of such person, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise (the "Total Payments"), would be subject to the excise tax imposed by
Section 4999 of the Code or any interest or penalties with respect to such
excise tax (such excise tax, together with any such interest or penalties, are
collectively referred to as the "Excise Tax"), then the Total Payments shall be
either (i) the full payment or (ii) such lesser amount that would result in no
portion of the payment being subject to excise tax under Section 4999 of the
Code, whichever of the foregoing amounts, taking into account the applicable
federal, state and local employment taxes, income taxes and the Excise Tax,
results in the receipt by the Executive, on an after-tax basis, of the greatest
amount of the Total Payments notwithstanding that all or some portion of the
Total Payments may be taxable under Section 4999 of the Code.

         (b) Determination by Auditors. All mathematical determinations and all
determinations of whether any of the Total Payments are "parachute payments"
(within the meaning of Section 280G of the Code) that are required to be made
under this Section 5, shall be made by the independent auditors retained by the
Company most recently prior to the Change in Control (the "Auditors"), who shall
provide their determination (the "Determination"), together with detailed
supporting calculations regarding the amount of any relevant matters, both to
the Company and to the Executive within seven (7) business days of the
Executive's termination date, if applicable, or such earlier time as is
requested by the Company or by the Executive. The Auditors shall furnish the
Executive with a written statement that such Auditors have concluded

                                      -5-
<PAGE>
that no Excise Tax is payable (including the reasons therefor) and that the
Executive has substantial authority not to report any Excise Tax on the
Executive's federal income tax return. Any Determination by the Auditors shall
be binding upon the Company and the Executive, absent manifest error. The
Company shall pay the fees and costs of the Accountants.

6.       Successors.

         (a) Company's Successors. The Company shall require any successor and
assigns (whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Company's business and/or assets, by an agreement in substance and form
satisfactory to the Executive, to assume this Agreement and to agree expressly
to perform this Agreement in the same manner and to the same extent as the
Company would be required to perform it in the absence of a succession.

         (b) Executive's Successors. This Agreement and all rights of the
Executive hereunder shall inure to the benefit of, and be enforceable by, the
Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees.

7.       Miscellaneous Provisions.

         (a) Notice. Notices and all other communications contemplated by this
Agreement shall be in writing and shall be deemed to have been duly given when
personally delivered or when mailed by U.S. registered or certified mail, return
receipt requested and postage prepaid. In the case of the Executive, mailed
notices shall be addressed to him or her at the home address that he or she most
recently communicated to the Company in writing. In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its CEO and President.

         (b) Waiver. No provision of this Agreement shall be modified, waived or
discharged unless the modification, waiver or discharge is agreed to in writing
and signed by the Executive and by an authorized officer of the Company (other
than the Executive). No waiver by either party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party
shall be considered a waiver of any other condition or provision or of the same
condition or provision at another time.

         (c) Entire Agreement. No agreements, representations or understandings
(whether oral or written and whether express or implied) that are not expressly
set forth in this Agreement have been made or entered into by either party with
respect to the subject matter hereof.

         (d) No Setoff; Withholding Taxes. There shall be no right of setoff or
counterclaim, with respect to any claim, debt or obligation, against payments to
the Executive under this Agreement. All payments made under this Agreement shall
be subject to reduction to reflect taxes required to be withheld by law.

         (e) Choice of Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the state of
Washington.

                                      -6-

         SCOLR, INC., a Delaware corporation (the "Issuer"), for value received,
hereby promises to pay to __________ , or registered assigns, the principal sum

punctually paid, on any Interest Payment Date will be paid to the person (the
"Registered Holder") in whose name this Note is registered at the close of

in whose name this Note is registered at the close of business on such Regular
Record Date.

                           (a)  So long as any Notes remain Outstanding (as
defined in Section 13), the Issuer shall maintain at its principal executives
offices in the United States an office or agency where Notes may be presented or
surrendered for payment, where Notes may be surrendered for registration of
transfer or exchange, where Notes may be surrendered for conversion pursuant to
Sections 9 or 10 hereof, and where notices and demands to or upon the Issuer in
respect of the Notes may be served. The Issuer will at all times act as its own
note registrar and paying and transfer agent for such purposes and agrees to
cause to be kept at such office a register (the "Note Register") in which,
subject to such reasonable regulations as it may prescribe, the Issuer will
provide for the registration of Notes and registration of transfers of Notes. As
of the date this Note was originally issued, such principal executive offices of
the Issuer were located at 8340 154th Avenue N.E., Redmond, Washington 98052.
The Issuer shall not change the location of its principal executive offices
unless the Issuer provides all Registered Holders with no less than thirty (30)
days prior written notice.

                           (b)  The transfer of a Note is registrable on the
Note Register upon surrender of such Note at the principal executive offices of
the Issuer duly endorsed by, or accompanied by a written instrument of transfer
in form reasonably satisfactory to the Issuer duly executed by the Registered
Holder thereof, or the Registered Holder's attorney duly authorized in writing,
together with any certifications and representations which the Issuer may
reasonably require to reflect compliance with all applicable securities laws,
rules and regulations and the due authorization of the transaction. Upon such
surrender of this Note for registration of transfer, the Issuer shall execute
and deliver, in the name of the designated transferee or transferees, one or
more new Notes, dated the date of the execution thereof, of any authorized
denominations and of a like tenor, form and aggregate principal amount.

                           (c)  At the option of the Registered Holder, upon
request confirmed in writing, Notes may be exchanged for Notes of any authorized
denominations and of a like tenor, form and aggregate principal amount upon
surrender of the Notes to be exchanged at the principal executive offices of the
Issuer. Whenever any Notes are so surrendered for exchange, the Issuer shall
execute and deliver the Notes which the Registered Holder making the exchange is
entitled to receive. Any registration of transfer or exchange will be effected
only upon the

                                        3

<PAGE>

Issuer being reasonably satisfied with the documents of title and identity of
the person making the request and subject to compliance with applicable Federal
and state securities laws.

                           (d)  All Notes issued upon any registration of
transfer or exchange of Notes shall be the valid obligations of the Issuer,
evidencing the same debt, and entitled to the same benefits, as the Notes
surrendered upon such registration of transfer or exchange. No service or other
charges shall be made for any registration of transfer or exchange, but the
Issuer may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

                           (e)  Prior to due presentment of this Note for
registration of transfer, the Issuer may treat the person in whose name this
Note is registered as the owner hereof for all purposes, whether or not this
Note be overdue, and the Issuer shall not be affected by notice to the contrary.

                  4.       Payments When Banking Institutions are Closed. In any
case where the due date for the payment of the principal of or interest on any
Note shall be, at any place of payment, a day on which banking institutions are
authorized or obligated by law to close, then payment of principal or interest,
as the case may be, need not be made on such date at such place but may be made
on the next succeeding day at such place which is not a day on which banking
institutions are authorized or obligated by law to close, with the same force
and effect as if made on the date for such payment, and interest shall accrue
and be paid for the period through and including the date of payment.

                  5.       Taxes.

                           (a)      The Issuer shall pay all stamp and other
duties and taxes, if any, which may be imposed by the United States or any
political subdivision thereof, any state or any political subdivision thereof or
any other taxing authority with respect to the issuance of the Notes.

                           (b)      Except as specifically provided in this
Note, the Issuer shall not be required to make any payment with respect to any
tax, assessment or other governmental charge imposed by any government or any
political subdivision or taxing authorities thereof or therein.

                  6.       Representations and Warranties of the Issuer. The
Issuer hereby makes to the Registered Holder as of the Original Issue Date the
same representations and warranties which the Issuer makes in Section 2 of that
certain Note Purchase Agreement ("Purchase Agreement") entered into between the
Issuer and the original Registered Holder of this Note on or about the Original
Issue Date. Such representations and warranties are incorporated herein by
reference and are hereby deemed to be made by the Issuer to the Registered
Holder as though the Registered Holder were the "Purchaser" in said Section 2 of
the Purchase Agreement.

                  7.       Covenants of the Issuer. The Issuer hereby covenants
and agrees that for so long as any of the Notes shall remain Outstanding:

                           (a)      it will duly and punctually pay the
principal of and any interest on the Notes in accordance with the terms hereof;

                           (b)      it will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence, rights
(charters and statutory) and franchises;

                           (c)      it will cause all material properties used
or useful in the conduct of its business to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the reasonable judgment of the
Issuer may be necessary so that the business carried on in connection therewith
may be properly and advantageously conducted at all times; provided, however,
that the foregoing shall not prevent the Issuer from discontinuing the operation
or maintenance of any such properties if such discontinuance is, in the
reasonable judgment of the Issuer, desirable in the conduct of its business or
the business of any of its subsidiaries, and not disadvantageous in any material
respect to the holders of Notes; and, provided, further, that the failure to
comply herewith shall not be deemed a breach or Event of Default (as hereinafter
defined) hereof unless such failure would have a material adverse effect on the
business, financial condition or results of operations of the Issuer and its
subsidiaries, taken as a whole (a "Material Adverse Effect");

                           (d)      it will pay or discharge or cause to be paid
or discharged, before the same shall become delinquent, (i) all taxes,
assessments and governmental charges levied or imposed upon the Issuer or upon
the income, profits or property of the Issuer, and (ii) all lawful claims for
labor, materials and supplies which, if unpaid, might by law become a lien upon
the property of the Issuer; provided, however, that the Issuer shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings; and, provided, further, that
the failure to comply herewith shall not be deemed a breach or Event of Default
if it would not have a Material Adverse Effect;

                           (e)      it will furnish to each Registered Holder of
Notes a copy of all documents it is required to send to its shareholders at the
time the same are sent to shareholders, including, without limitation, annual
reports and proxy statements;

                           (f)      as soon as it becomes aware of the same, it
will give written notice to each Registered Holder of Notes of any event or
occurrence which by itself or with notice or lapse of time or both would entitle
the holders of the Notes to declare the principal of and any interest on the
Notes immediately due and payable pursuant to Section 15 hereof, and it will
give

                                        5

<PAGE>

written notice to each Registered Holder of Notes and to the Collateral Agent
(as defined below) immediately upon the occurrence of a Probiotics Sale or the
Release of Liens (each as defined below);

                           (g)      it will promptly obtain and maintain from
time to time all authorizations, permits, approvals, consents, licenses and
exemptions which are required under any applicable law or regulation to enable
it to perform all of its payment, conversion and other material obligations
under the Notes or which may be required for the validity or enforceability of
the Notes; provided, however, that the failure to obtain and maintain such
authorizations, permits, approvals, consents, licenses and exemptions as to
material obligations other than payment and conversion shall not constitute a
breach or Event of Default unless such non-compliance materially adversely
affects the Issuer's ability to comply with its obligations under the Notes;

                           (h)      it will duly and punctually comply with and
observe all statutes now or hereafter in force and all ordinances, regulations
and by-laws thereunder and all requirements and orders of any government or
other public authority, provided, however, that the failure to comply herewith
shall not be deemed a breach or Event of Default if it would not have a Material
Adverse Effect;

                           (i)      subject to reasonable limitations as may be
imposed by the Issuer, it will permit any representative of any Registered
Holder or Holders of at least $250,000 aggregate principal amount of the Notes
to make, during normal business hours and after reasonable notice, inspections
of the property of, and business operations being carried out by, the Issuer or
any of its subsidiaries;

                           (j)      it will maintain and keep in force with
reputable insurers and in adequate amounts, property, casualty, third party
liability, business interruption and all such other insurances as would
prudently be effected and maintained in the case of a company carrying on a
business similar to that of the Issuer;

                           (k)      it will authorize and reserve a sufficient
number of shares of Common Stock to provide for conversion of the Notes into
shares of Common Stock;

                           (l)      it will not incur any additional
indebtedness which is senior in priority to the Notes unless such indebtedness
is to a financial institution and is secured by all or substantially all of the
Issuer's assets and properties;

                           (m)      in the event of a Probiotics Sale (as
defined below), it will repay in full the amounts it owes to lenders that, as of
the Original Issue Date, have a security interest in the Issuer's assets; and

                                        6

<PAGE>

                           (n)      simultaneously with the release of the liens
on the Issuer's assets existing as of the Original Issue Date ("Release of
Liens"), either in connection with the sale or other disposition of all or
substantially all of the business described in the Memorandum as the Issuer's
probiotics business or the assets relating thereto (a "Probiotics Sale") or
earlier for any other reason, the Company shall grant to Taglich Brothers, Inc.
or its designee (the "Collateral Agent"), as agent for the Registered Holders, a
first priority security interest, which security interest shall be fully
perfected, on all of the intellectual property in which the Issuer holds any
rights or interests, including, but not limited to, all trademarks, trade names,
service marks, designs, styles, copyrights, patents and derivative works,
applications, registrations, recordings and goodwill relating to any of the
foregoing.

                  8.       Registration Rights; Collateral Agent.

                           This Note is subject to the Registration Rights
provisions set forth in Supplement A hereto and the Conversion Price (as
hereinafter defined) is subject to reduction in accordance with the provisions
set forth in such Supplement A. By accepting this Note or receiving any benefits
hereunder, the Registered Holder, and each successor Registered Holder, (i)
hereby agrees to the provisions set forth in Supplement A hereto and (ii) hereby
appoints Taglich Brothers, Inc. as the Collateral Agent with the right to
designate any successor Collateral Agents.

                  9.       Voluntary Conversion.

                           (a)      Each Registered Holder of Notes may at any
time convert all or any amount of the principal amount of the Notes then owned
by such Registered Holder into shares of Common Stock of the Issuer at a
conversion price equal to $1.05 (One Dollar Five Cents) per share of Common
Stock, subject to adjustment as provided in this Section 9 and in Supplement A.

                           (b)      The conversion right granted in Section 9(a)
hereof may be exercised only by a Registered Holder of Notes, in whole or in
part, by the surrender of the certificate or certificates representing the Notes
to be converted at the principal executive offices of the Issuer against
delivery of that number of shares of whole Common Stock as shall be computed by
dividing the face amount of the Notes being converted by the Conversion Price on
the Conversion Date. At the time of conversion of Notes, the Issuer shall pay in
cash to the Registered Holder thereof an amount equal to all accrued and unpaid
interest, if any, to and including the Conversion Date. Each Note surrendered
for conversion shall be endorsed by the Registered Holder. The Issuer will
transmit the Common Stock certificates issuable upon conversion of any Notes and
a certificate representing the balance of the Notes to the Registered Holder via
express courier within three (3) business days after the Conversion Date. The
term "Conversion Date" shall mean the date the original Notice of Conversion and
Notes being converted are received by the Issuer. The term "Notice of
Conversion" shall mean the written

                                        7

<PAGE>

notice from the Registered Holder to the Issuer requesting conversion of the
Note or Notes pursuant to this Section 9.

                           (c)      All Common Stock which may be issued upon
conversion of the Notes will, upon issuance, be duly issued, fully paid and
non-assessable and free from all taxes, liens, and charges with respect to the
issue thereof. At all times that any Notes are Outstanding, the Issuer shall
have authorized and shall have reserved for the purpose of issuance upon such
conversion into Common Stock of all Notes, a sufficient number of shares of
Common Stock to provide for the conversion of all Outstanding Notes at the then
effective Conversion Price. Without limiting the generality of the foregoing,
if, at any time, the Conversion Price is decreased or increased, the number of
shares of Common Stock authorized and reserved for issuance by the Issuer upon
the conversion of the Notes shall be proportionately increased or decreased, as
the case may be.

                           (d)      The Initial Conversion Price is $1.05 (One
Dollar Five Cents) per share of Common Stock ("Initial Conversion Price"). The
Initial Conversion Price shall be adjusted as provided for below in this Section
9(d) (the Initial Conversion Price and the Initial Conversion Price, as
thereafter then adjusted, shall be referred to as the "Conversion Price") and
the Conversion Price from time to time shall be further adjusted as provided for
below in this Section 9(d). Upon each adjustment of the Conversion Price, the
Registered Holders of the Notes shall thereafter be entitled to receive upon
conversion, at the Conversion Price resulting from such adjustment, the number
of shares of Common Stock obtained by dividing the face amount of the Notes
being converted by the Conversion Price, as then adjusted. The Conversion Price
shall be adjusted as follows:

                                    (i)      In the case of any amendment to the
Certificate of Incorporation of the Issuer to change the designation of the
Common Stock or the rights, privileges, restrictions or conditions in respect to
the Common Stock or division of the Common Stock, the Notes shall be adjusted so
as to provide that upon conversion thereof the Registered Holder shall receive,
in lieu of each share of Common Stock theretofore issuable upon such conversion,
the kind and amount of shares, other securities, money and property receivable
upon such designation, change or division by such holder issuable upon such
conversion had the conversion occurred immediately prior to such designation,
change or division. The Notes shall be deemed thereafter to provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 9. The provisions of this Subsection
9(d)(i) shall apply in the same manner to successive reclassifications, changes,
consolidations and mergers.

                                    (ii)     If the Issuer shall at any time
subdivide its outstanding shares of Common Stock into a greater number of shares
of Common Stock, or declare a dividend or make any other distribution upon the
Common Stock payable in shares of Common Stock, the Conversion Price in effect
immediately prior to such subdivision or dividend or other

                                        8

<PAGE>

distribution shall be proportionately reduced, and conversely, in case the
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Conversion Price in effect immediately prior to such
combination shall be proportionately increased.

                                    (iii)    If the Issuer shall at any time
issue or otherwise sell or distribute shares of Common Stock for a consideration
per share in cash or property, or the Issuer shall issue options, warrants or
other rights to purchase Common Stock that are exercisable at, or the Issuer
shall issue or otherwise sell or distribute rights to subscribe for or
securities convertible into or exchangeable for Common Stock at, a price that is
less than the then effective Conversion Price (the "Lower Price"), the
Conversion Price then in effect shall automatically be reduced to the Lower
Price. Notwithstanding anything herein to the contrary, no adjustment shall be
made to the Conversion Price upon any of: (A) the grant or exercise of options
to purchase Common Stock pursuant to directors' and employee stock option and
stock purchase plans; (B) shares or options issued in connection with an
acquisition of another entity (regardless of whether such acquisition is
consummated by the purchase of assets or equity securities) or in connection
with a licensing transaction to which the Issuer is a party; (C) the exercise of
any options, warrants or other rights to purchase Common Stock or upon
conversion of any securities or other rights convertible into Common Stock,
which options, warrants, securities or other rights were outstanding as of April
30, 2003; or (D) the issuance, sale or distribution by the Issuer of up to
750,000 shares of Common Stock in the aggregate (regardless of price).

                                    (iv)     For purposes of the foregoing
subsection (d)(iii)

                                    (A)      the consideration for the issue or
sale of any shares of Common Stock shall, irrespective of the accounting
treatment of such consideration,

                                             (1) insofar as it consists of cash,
                  be computed at the amount of cash received by the Issuer,
                  without deducting any expenses paid or incurred by the Issuer
                  or any commissions or compensations paid or concessions or
                  discounts allowed to underwriters, dealers or others
                  performing similar services in connection with such issue or
                  sale,

                                             (2) insofar as it consists of
                  property (including securities) other than cash, be computed
                  at the Fair Value (as hereinafter defined) thereof at the time
                  of such issue or sale, and

                                             (3) in the case where shares of
                  Common Stock are issued or sold together with other stock or
                  securities or other assets of the Issuer for a consideration
                  which covers both, be the portion of such consideration so
                  received, computed as provided in clauses (1) and (2) above,
                  allocable to such shares of Common Stock, such allocation to
                  be determined in the same manner that the Fair

                                        9

<PAGE>

                  Value of property not consisting of cash or securities is to
                  be determined as provided in the definition of "Fair Value"
                  herein;

                                    (B)      Shares of Common Stock deemed to
have been issued pursuant to the foregoing subsection (d)(iii), relating to
stock options and convertible securities, shall be deemed to have been issued
for a consideration per share determined by dividing

                                             (1) the total amount, if any,
                  received and receivable by the Issuer as consideration for the
                  issue, sale, grant or assumption of the stock options or
                  convertible securities in question, plus the minimum aggregate
                  amount of additional consideration (as set forth in the
                  instruments relating thereto, without regard to any provision
                  contained therein for a subsequent adjustment of such
                  consideration to protect against dilution) payable to the
                  Issuer upon the exercise in full of such options or the
                  conversion or exchange of such convertible securities or, in
                  the case of options for convertible securities, the exercise
                  of such options for convertible securities and the conversion
                  or exchange of such convertible securities, in each case
                  computing such consideration as provided in the foregoing
                  subdivision (A),

                  by

                                             (2) the maximum number of shares of
                  Common Stock (as set forth in the instruments relating
                  thereto, without regard to any provision contained therein for
                  a subsequent adjustment of such number to protect against
                  dilution) issuable upon the exercise of such options or the
                  conversion or exchange of such convertible securities;

                                    (C)      Should the Conversion Price be
adjusted for shares of Common Stock deemed to have been issued pursuant to the
foregoing subsection (d)(iii), relating to stock options and convertible
securities, upon the expiration of any such stock option or convertible security
or termination of any right to convert or exchange such convertible security, to
the extent such options or convertible securities are not exercised, converted
or exchanged, the Conversion Price then in effect hereunder shall forthwith be
adjusted to the Conversion Price which would have been in effect at the time of
such expiration or termination had such option or convertible security, to the
extent outstanding immediately prior to such expiration or termination, never
been issued;

                                    (D)      With respect to stock options and
convertible securities issued by the Issuer after the date set forth in the
foregoing subsection (d)(iii)(C), no adjustment to the Conversion Price pursuant
to the foregoing subsection (d)(iii) will be made upon exercise or conversion of
such options or convertible securities, provided, however, that any downward
adjustment to the exercise or conversion price of any such option or convertible
security pursuant

                                       10

<PAGE>

to any reset provision shall cause the Conversion Price to be recomputed in
accordance with subsection (d)(iii) to reflect such adjustment; and

                                    (E)      "Fair Value" means, on any date
specified herein (1) in the case of cash, the dollar amount thereof, (2) in the
case of a security admitted for trading on any national securities exchange or
Nasdaq or quoted in the over-the-counter market, the 10-day average closing bid
prices of a share of such security as reported on such exchange or market for
the period of 10 consecutive trading days ending on the date of determination,
and (3) in all other cases as determined in good faith by the Issuer's Board of
Directors.

                                    (v)      If any capital reorganization or
reclassification of the capital stock of the Issuer, or any consolidation or
merger of the Issuer with another corporation or entity, or the sale of all or
substantially all of the Issuer's assets to another corporation or other entity
shall be effected in such a way that holders of shares of Common Stock shall be
entitled to receive stocks, securities, other evidence of equity ownership or
assets with respect to or in exchange for shares of Common Stock, then, as a
condition of such reorganization, reclassification, consolidation, merger or
sale (except as otherwise provided below in this Section 9), lawful and adequate
provisions shall be made whereby the Registered Holder shall thereafter have the
right to receive upon the basis and upon the terms and conditions specified
herein, such shares of stock, securities, other evidence of equity ownership or
assets as may be issued or payable with respect to or in exchange for a number
of outstanding shares of such Common Stock equal to the number of shares of
Common Stock immediately theretofore purchasable and receivable upon the
conversion of this Note under this Section 9 had such reorganization,
reclassification, consolidation, merger or sale not taken place, and in any such
case appropriate provisions shall be made with respect to the rights and
interests of such Registered Holder to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the Conversion
Price and of the number of shares of Common Stock receivable upon the conversion
of this Note) shall thereafter be applicable, as nearly as may be, in relation
to any shares of stock, securities, other evidence of equity ownership or assets
thereafter deliverable upon the conversion hereof (including an immediate
adjustment, by reason of such consolidation or merger, of the Conversion Price
to the value for the Common Stock reflected by the terms of such consolidation
or merger if the value so reflected is less than the Conversion Price in effect
immediately prior to such consolidation or merger). Subject to the terms of this
Note, in the event of a merger or consolidation of the Issuer with or into
another corporation or other entity as a result of which the number of shares of
common stock of the surviving corporation or other entity issuable to holders of
Common Stock of the Issuer, is greater or lesser than the number of shares of
Common Stock of the Issuer outstanding immediately prior to such merger or
consolidation, then the Conversion Price in effect immediately prior to such
merger or consolidation shall be adjusted in the same manner as though there
were a subdivision or combination of the outstanding shares of Common Stock of
the Issuer. The Issuer shall not effect any such consolidation, merger or sale,
unless, prior to the consummation thereof, the successor corporation (if other
than the Issuer) resulting from such

                                       11

<PAGE>

consolidation or merger or the corporation purchasing such assets shall assume
by written instrument executed and mailed or delivered to the Registered Holder,
the obligation to deliver to the Registered Holder such shares of stock,
securities, other evidence of equity ownership or assets as, in accordance with
the foregoing provisions, the Registered Holder may be entitled to receive or
otherwise acquire. If a purchase, tender or exchange offer is made to and
accepted by the holders of more than fifty percent (50%) of the outstanding
shares of Common Stock of the Issuer, the Issuer shall not effect any
consolidation, merger or sale with the Person having made such offer or with any
Affiliate (as hereinafter defined) of such Person, unless prior to the
consummation of such consolidation, merger or sale the Registered Holder of this
Note shall have been given a reasonable opportunity to then elect to receive
upon the conversion of this Note the amount of stock, securities, other evidence
of equity ownership or assets then issuable with respect to the number of shares
of Common Stock of the Issuer in accordance with such offer.

                           (e)      Whenever the Conversion Price shall be
adjusted pursuant to Section 9(d) hereof, the Issuer shall issue a certificate
signed by its President or Vice President and by its Treasurer, Assistant
Treasurer, Secretary or Assistant Secretary, setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board of Directors of the Issuer made any determination
hereunder), and the Conversion Price after giving effect to such adjustment, and
shall cause copies of such certificates to be mailed (by first-class mail,
postage prepaid) to each Registered Holder of Notes. The Issuer shall make such
certificate and mail it to each such holder promptly after each adjustment.

                           (f)      No fractional Common Stock shall be issued
in connection with any conversion (or forced conversion, if applicable) of
Notes, but in lieu of such fractional shares, the Issuer shall make a cash
payment therefor equal in amount to the product of the applicable fraction
multiplied by the Conversion Price then in effect.

                  10.      Forced Conversion. All, but not less than all, of the
principal amount of the outstanding Notes are convertible, at the option of the
Issuer, into shares of Common Stock at the Conversion Price, provided that on
the day that the Forced Conversion Notice (as hereinafter defined) is given by
the Issuer to all Registered Holders and on the Forced Conversion Date (as
hereinafter defined), the following conditions are satisfied: (i) the Conversion
Shares have been registered by the Issuer pursuant to the 1933 Act as provided
for in Section 8 above and Supplement A hereto and such registration is then
currently effective; and (ii) the average of the closing bid price per share of
the Common Stock, as reported on the principal national securities exchange or
quotation system on which the Common Stock then trades, during twenty (20)
trading days out of the thirty (30) consecutive trading days ending five (5)
trading days immediately prior to the date the Forced Conversion Notice is sent,
is at least two hundred percent (200%) of the Conversion Price. Any notice of
conversion ("Forced Conversion Notice") must be given by the Issuer to all
Registered Holders no less than thirty (30) days nor

                                       12

<PAGE>

more than forty-five (45) days prior to the date set forth for conversion (the
"Forced Conversion Date"). The Forced Conversion Notice shall remain effective
only if the registration statement provided for in Section 8 and Supplement A
remains effective continually throughout the notice period. On the Forced
Conversion Date, the Issuer shall pay to all Registered Holders of Notes, all
accrued and unpaid interest on the Notes through and including the Forced
Conversion Date.

                  11.      Change of Control.

                           (a)      In the event of a Change of Control (as
hereinafter defined) of the Issuer, the Issuer shall immediately notify each
Registered Holder. Each Registered Holder may, within fifteen (15) days after
written notice from the Issuer, elect to accelerate the maturity date of the
Note owned by such Registered Holder to a date not less than thirty (30) but not
more than forty-five (45) days after the date of such notice from the Issuer
("Redemption Date").

                           (b)      For purposes hereof, a "Change of Control"
shall be deemed to have occurred if (i) any "person" (as such term is defined at
Section 13(d) of the Securities Exchange Act of 1934) other than the Issuer or
an entity then controlled by the Issuer is or becomes the beneficial owner,
directly or indirectly of securities of the Issuer representing fifty percent
(50%) or more of the combined voting power of the Issuer's then outstanding
securities, including securities such person may have acquired directly from the
Issuer; (ii) the Issuer merges or consolidates with another corporation and the
holders of one-hundred percent (100%) of the voting power of the Issuer
immediately prior to the merger or consolidation do not own, immediately after
the merger or consolidation, fifty percent (50%) or more of the voting power of
the surviving entity; or (iii) a sale, lease, exchange or other disposition of
all or substantially all of the assets of the Issuer takes place, provided,
however, that a sale of any or all of the assets comprising the Issuer's
probiotics business shall not be deemed a Change of Control for purposes hereof.

                  12.      Issuance of New Notes.

                           (a)      If any mutilated Note is surrendered to the
Issuer, the Issuer shall execute and deliver in exchange therefor a new Note of
like tenor and principal amount, bearing a number not contemporaneously
outstanding.

                           (b)      If there is delivered to the Issuer (a)
evidence to its reasonable satisfaction of the destruction, loss or theft of any
Note and (b) such reasonable security or indemnity as may be required by it to
save it harmless, then, in the absence of notice to the Issuer that such Note
has been acquired by a bona fide purchaser, the Issuer shall execute and deliver
in lieu of any such destroyed, lost or stolen Note a new Note of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

                           (c)      Upon the issuance of any new Note under this
Section 12, the Issuer

                                       13

<PAGE>

may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses connected therewith.

                           (d)      Any new Note delivered pursuant to this
Section 12 shall be so dated that neither gain nor loss in interest shall result
from such exchange.

                           (e)      The provisions of this Section 12 are
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Notes.

                  13.      Meetings.

                           (a)      A meeting of holders of the Notes may be
called at any time and from time to time to make, give or take any request,
demand, authorization, direction, notice, consent, waiver or other action
provided by the Notes to be made, given or taken by holders of Notes or to
modify, amend or supplement the terms of the Notes as hereinafter provided.
Notice of every meeting of holders of Notes, setting forth the time and the
place of such meeting and in general terms the action proposed to be taken at
such meeting, shall be given as provided for in the terms of the Notes, not less
than fifteen (15) nor more than sixty (60) days prior to the date fixed for the
meeting. Such meetings may be called at any time for any such purpose by the
Issuer or by the holders of at least twenty-five percent (25%) in the aggregate
principal amount of the Outstanding Notes by, in the case of the holders,
written request to the Issuer setting forth in reasonable detail the action
proposed to be taken at the meeting. Upon receipt of any such request, the
Issuer shall call such meeting for such purposes by giving notice thereof.

                           (b)      To be entitled to vote at any meeting of
holders of Notes, a person shall be a registered holder of Outstanding Notes or
a person duly appointed by an instrument in writing as proxy for such a holder.
The persons entitled to vote more than fifty percent (50%) in principal amount
of the Outstanding Notes shall constitute a quorum. The Issuer may make such
reasonable and customary regulations as it shall deem advisable for any meeting
of holders of Notes with respect to the appointment of proxies in respect of
holders of Notes, the record date for determining the registered owners of Notes
who are entitled to vote at such meeting (which date shall be set forth in the
notice calling such meeting hereinabove referred to and which shall be not less
than fifteen (15) nor more than sixty (60) days prior to such meeting), the
adjournment and chairmanship of such meeting, the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall deem appropriate.

                           (c)      At any meeting of holders of Notes duly
called and held as specified above, upon the affirmative vote, in person or by
proxy thereunto duly authorized in writing, of the Registered Holders of not
less than seventy-five percent (75%) in aggregate principal amount of
Outstanding Notes, or with the written consent of the Registered Holders of not
less than

                                       14

<PAGE>

seventy-five percent (75%) in aggregate principal amount of Outstanding Notes,
the Issuer may modify, amend or supplement the terms of the Notes in any way,
and the holders of Notes may make, take or give any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
the terms of the Notes to be made, given or taken by holders of Notes; provided,
however, that no such action may, without the consent of Registered Holders of
Notes owning ninety percent (90%) or more in the aggregate principal amount of
Outstanding Notes affected thereby, (a) change the due date for the payment of
the principal of or any installment of interest on any Note, (b) reduce the
principal amount of any Note, the portion of such principal amount which is
payable upon acceleration of the maturity of such Note or the interest rate
thereon, (c) change the coin or currency in which or the required places at
which payment with respect to interest or principal in respect of Notes is
payable, (d) permit the Issuer to redeem the Notes (other than as specifically
provided in this Note), or (e) reduce the proportion of the principal amount of
Notes the vote or consent of the holders of which is necessary to modify, amend
or supplement the terms and conditions of the Notes or to make, take or give any
request, demand, authorization, direction, notice, consent, waiver or other
action provided hereby or thereby to be made, taken or given.

                           (d)      Any instrument given by or on behalf of any
Registered Holder of a Note in connection with any consent to or vote for any
such modification, amendment, supplement, request, demand, authorization,
direction, notice, consent, waiver or other action will be irrevocable once
given and will be conclusive and binding on all subsequent holders of such Note
or any Note issued directly or indirectly in exchange or substitution therefor
or in lieu thereof. Any such modification, amendment, supplement, request,
demand, authorization, direction, notice, consent, waiver or other action will
be conclusive and binding on all holders of Notes, whether or not they have
given such consent or cast such vote, and whether or not notation of such
modification, amendment, supplement, request, demand, authorization, direction,
notice, consent, waiver or other action is made upon the Notes. Notice of any
modification or amendment of, supplement to, or request, demand, authorization,
direction, notice, consent, waiver or other action with respect to the Notes
shall be given to each registered holder of Notes affected thereby, in all cases
as provided herein.

                           (e)      Notes executed and delivered after the
effectiveness of any such modification, amendment, supplement, request, demand,
authorization, direction, notice, consent, waiver or other action shall bear a
notation in the form reasonably approved by the Issuer as to any matter provided
for in such modification, amendment, supplement, request, demand, authorization,
direction, notice, consent, waiver or other action. New Notes modified to
conform to any such modification, amendment, supplement, request, demand,
authorization, direction, notice, consent, waiver or other action may be
prepared by the Issuer and executed and delivered in exchange for Outstanding
Notes.

                           (f)      For purposes of the provisions of the Notes,
any Note executed and delivered by the Issuer shall, as of any date of
determination, be deemed to be "Outstanding",

                                       15

<PAGE>

except:

                                    (i)      Notes theretofore canceled by the
Issuer or delivered to the Issuer for conversion or cancellation or held by the
Issuer for reissuance but not reissued by the Issuer; or

                                    (ii)     Notes that have become due and
payable at Maturity or otherwise and with respect to which monies sufficient to
pay the principal thereof and any interest thereon shall have been made
available to the Registered Holders thereof; or

                                    (iii)    Notes in lieu of or in substitution
for which other Notes shall have been authenticated and delivered pursuant to
the terms of the Notes;

provided, however, that in determining whether the Registered Holders of the
requisite principal amount of Outstanding Notes are present at a meeting of
holders of Notes for quorum purposes or have consented to or voted in favor of
any request, demand, authorization, direction, notice, consent, waiver,
amendment, modification or supplement hereunder, Notes owned directly or
indirectly by the Issuer or any Affiliate of the Issuer shall be disregarded and
deemed not to be Outstanding.

                  14.      Notice. Where the terms of the Notes provide for
notice to the holders of any event, such notice shall be sufficiently given if
given in writing and mailed, first class postage prepaid, to each Registered
Holder affected by such event, at his address as it appears in the register for
the Notes. Any notice may be waived in writing by the Person entitled thereto,
either before or after the event, and such waiver shall be equivalent of such
notice.

                  15.      Events of Default. The occurrence of any of the
following events or conditions shall constitute an event of default ("Event of
Default") with respect to the Issuer:

                           (a)      Any interest due under this Note, or any of
the other Notes, is not paid within five (5) days after the date such interest
is due; or

                           (b)      The principal amount of this Note, or any of
the other Notes, is not paid at Maturity; or

                           (c)      The Issuer (i) becomes insolvent or is
unable generally to pay its debts or fails or admits in writing its inability
generally to pay its debts as they become due; (ii) makes a general assignment,
arrangement or composition with or for the benefit of its creditors; (iii)
institutes or has instituted against it a proceeding seeking a judgment of
insolvency or bankruptcy or any other relief under any bankruptcy or insolvency
law or other similar law affecting creditors' rights, (iv) has a distress,
execution, attachment, sequestration or other legal process levied, enforced or
sued on or against all or substantially all its assets; (v) causes or is

                                       16

<PAGE>

subject to any event with respect to it which, under the applicable laws of any
jurisdiction, has an analogous effect to any of the events specified in clauses
(i) through (iv); or (vi) takes any action in furtherance of, or indicating its
consent to, approval of, or acquiescence in, any of the foregoing acts; or

                           (d)      The Issuer materially breaches any other
covenant, agreement or condition set forth in the Notes or in the Purchase
Agreement and such breach remains uncured for a period of ten (10) days after
the Issuer is first given written notice of such breach by a Registered Holder
or Holder(s) of a Note or Notes representing twenty-five percent (25%) or more
of the aggregate principal amount of the Notes; or

                           (e)      Any representation or warranty made by the
Issuer in any of the Notes or in the Purchase Agreement shall prove to have been
false, incorrect or misleading in any material respect on the date as of which
made; or

                           (f)      The Issuer defaults under one or more bonds,
debentures, notes or other evidence of Indebtedness (as hereinafter defined) in
excess of $100,000 in the aggregate, whether such Indebtedness is secured or
unsecured and whether such Indebtedness now exists or shall hereinafter be
created, which default has not been cured within a period of thirty (30) days
after written notice is delivered to the Issuer of such default; or

                           (g)      The Memorandum contains any misstatement of
a material fact or omission of a material fact necessary to make the information
in the Memorandum not misleading (regardless of any investigation made by any
Registered Holders); or

                           (h)      Any final non-appealable judgment is entered
against the Issuer for an amount exceeding $50,000 or any of the Issuer's
properties or assets is attached or levied or a restraining notice is placed
thereon, provided, however, that no such judgment or action shall be deemed an
Event of Default unless the enforcement of such judgment or action shall have a
Material Adverse Effect on the Issuer; or

                           (i)      Any of the Notes or the Purchase Agreement

interest.

Upon the occurrence and during the continuance of an Event of Default, a
Registered Holder or Registered Holders of a Note or Notes representing
twenty-five percent (25%) or more of the aggregate principal amount of the Notes
may, at their option, declare the principal of this Note and the interest
accrued hereon to be due and payable immediately (such date being the
"Acceleration Date") by written notice to the Issuer at its principal executive
offices, and unless

                                       17

<PAGE>

all such defaults shall have been cured by the Issuer prior to receipt of such
written notice, the principal of this Note and the interest accrued thereon
shall become and be immediately due and payable, in which case the Issuer shall
immediately pay all such amounts without presentment, demand, protest or notice
of any kind.

                  16.      Expenses of Enforcement. The Issuer shall pay all

of or based upon this Note ("Action"); (b) waives, to the extent not prohibited
by applicable law, rule or regulation, and agrees not to assert, by way of

any such action brought in the aforementioned court is brought in an
inconvenient forum, that the venue of any such action brought in the
aforementioned court is improper, or that this Note may not be enforced in or by
such court, and (c) consents to service of process in any such Action by

supported, subject to any limitation as to amount contained in the instrument or
agreement creating or evidencing such Contingent Obligation; or in the case of
Contingent Obligations referred to in clause (iii) above, the mark-to-market
value of such Contingent Obligation at the relevant date of determination.

of an obligation (including, without limitation, any conditional sale or other

effect as the foregoing).

                        SUPPLEMENT A TO CONVERTIBLE NOTE

         Registration Rights.

                           (a)      As soon as possible after the Final Closing
Date (as defined in the Memorandum), but in no event later than sixty (60) days
after the Final Closing Date (regardless of whether the maximum principal amount
of Notes shall have been sold), the Issuer shall, at its sole cost and expense,
file a registration statement on the appropriate form under the 1933 Act with
the Securities and Exchange Commission ("SEC") covering the resale of all of the
Conversion Shares (collectively, the "Registrable Securities"), time being of
the essence. The Issuer will use its best efforts to have such registration
statement declared effective as soon as possible thereafter, and shall keep such
registration statement current and effective for at least three (3) years from
the Final Closing Date (as defined in the Memorandum), subject to extension for
the number of days by which the filing or effectiveness of the registration
statement is delayed beyond the 60 and 150-day periods contemplated in this
subsection (a), or until such earlier date as all of the Registrable Securities
registered pursuant to such registration statement shall have been sold or
otherwise transferred. If the registration statement is not filed within such
sixty (60) days, the Conversion Price shall be reduced (and concomitantly, the
number of Conversion Shares shall increase) by the percentage resulting from
multiplying three percent (3%) by the number of thirty (30) day periods, or any
part thereof, beyond such sixty (60) day period until the registration statement
covering the Registrable Securities is filed with the SEC. Notwithstanding
anything to the contrary contained herein, and in addition to the adjustments
set forth in the preceding sentence, if the registration statement shall not be
declared effective within 150 days after the Final Closing Date (regardless of
whether the maximum principal amount of Notes shall have been sold), then the
Conversion Price shall be reduced (and concomitantly the number of shares of
Common Stock issuable upon the conversion of the Notes shall increase) by the
percentage resulting from multiplying two percent (2%) by the number of thirty
(30) day periods, or any part thereof, beyond the 150-day period until the
registration statement described herein covering the Registrable Securities is
declared effective. Notwithstanding the foregoing, the Conversion Price shall
not be reduced pursuant to this subsection (a) by more than thirty-six percent
(36%) in the aggregate.

                           (b)      In the event the Issuer effects any
registration under the 1933 Act of any Registrable Securities pursuant to
subsection (a) above or subsection (g) below, the Issuer shall indemnify, to the
extent permitted by law, and hold harmless any Registered Holder whose
Registrable Securities are included in such registration statement (each, a
"Seller"), any underwriter, any officer, director, employee or agent of any
Seller or underwriter, and each other person, if any, who controls any Seller or
underwriter within the meaning of Section 15 of the 1933 Act, against any
losses, claims, damages or liabilities, judgment, fines, penalties, costs and
expenses, joint or several, or actions in respect thereof (collectively, the
"Claims"), to which each such indemnified party becomes subject, under the 1933
Act or otherwise, insofar as such Claims arise out of or are based upon any
untrue statement or alleged untrue statement of any material

                                       22

<PAGE>

fact contained in the registration statement or prospectus or any amendment or
supplement thereto or any document filed under a state securities or blue sky
law (collectively, the "Registration Documents") or insofar as such Claims arise
out of or are based upon the omission or alleged omission to state in any
Registration Document a material fact required to be stated therein or necessary
to make the statements made therein not misleading, and will reimburse any such
indemnified party for any legal or other expenses reasonably incurred by such
indemnified party in investigating or defending any such Claim; provided,
however, that the Issuer shall not be liable in any such case to the extent such
Claim is based upon an untrue statement or alleged untrue statement of a
material fact or omission or alleged omission of a material fact made in any
Registration Document in reliance upon and in conformity with written
information furnished to the Issuer by or on behalf of any indemnified party
specifically for use in the preparation of such Registration Document.

                           (c)      In connection with any registration
statement in which any Seller is participating, each Seller, severally and not
jointly, shall indemnify, to the extent permitted by law, and hold harmless the
Issuer, each of its directors, each of its officers who have signed the
registration statement, each other person, if any, who controls the Issuer
within the meaning of Section 15 of the 1933 Act, each other Seller and each
underwriter, any officer, director, employee or agent of any such other Seller
or underwriter and each other person, if any, who controls such other Seller or
underwriter within the meaning of Section 15 of the 1933 Act against any Claims
to which each such indemnified party may become subject under the 1933 Act or
otherwise, insofar as such Claims (or actions in respect thereof) are based upon
any untrue statement or alleged untrue statement of any material fact contained
in any Registration Document, or insofar as any Claims are based upon the
omission or alleged omission to state in any Registration Document a material
fact required to be stated therein or necessary to make the statements made
therein not misleading, and will reimburse any such indemnified party for any
legal or other expenses reasonably incurred by such indemnified party in
investigating or defending any such claim; provided, however, that such
indemnification or reimbursement shall be payable only if, and to the extent
that, any such Claim arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any
Registration Document in reliance upon and in conformity with written
information furnished to the Issuer by the Seller specifically for use in the
preparation thereof.

                           (d)      Any person entitled to indemnification under
subsection (b) or subsection (c) above shall notify promptly the indemnifying
party in writing of the commencement of any Claim if a claim for indemnification
in respect thereof is to be made against an indemnifying party under this
subsection (d), but the omission of such notice shall not relieve the
indemnifying party from any liability which it may have to any indemnified party
otherwise than under subsection (b) or subsection (c) above, except to the
extent that such failure shall materially adversely affect any indemnifying
party or its rights hereunder. In case any action is brought against the
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate in, and, to the

                                       23

<PAGE>

extent that it chooses, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party; and, after notice from the indemnifying
party to the indemnified party that it so chooses, the indemnifying party shall
not be liable for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable
costs of investigation; provided, however, that (i) if the indemnifying party
fails to take reasonable steps necessary to defend diligently the Claim within
twenty (20) days after receiving notice from the indemnified party that the
indemnified party believes it has failed to do so; (ii) if the indemnified party
who is a defendant in any action or proceeding which is also brought against the
indemnifying party reasonably shall have concluded that there are legal defenses
available to the indemnified party which are not available to the indemnifying
party; or (iii) if representation of both parties by the same counsel is
otherwise inappropriate under applicable standards of professional conduct, the
indemnified party shall have the right to assume or continue its own defense as
set forth above (but with no more than one firm of counsel for all indemnified
parties in each jurisdiction, except to the extent any indemnified party or
parties reasonably shall have concluded that there are legal defenses available
to such party or parties which are not available to the other indemnified
parties or to the extent representation of all indemnified parties by the same
counsel is otherwise inappropriate under applicable standards of professional
conduct) and the indemnifying party shall be liable for any reasonable expenses
therefor; provided, however, that no indemnifying party shall be subject to any
liability for any settlement of a Claim made without its consent (which may not
be unreasonably withheld, delayed or conditioned). If the indemnifying party
assumes the defense of any Claim hereunder, such indemnifying party shall not
enter into any settlement without the consent of the indemnified party if such
settlement attributes liability to the indemnified party (which consent may not
be unreasonably withheld, delayed or conditioned).

                           (e)      If for any reason the indemnity provided in
subsection (b) or subsection (c) above is unavailable, or is insufficient to
hold harmless, an indemnified party, then the indemnifying party shall
contribute to the amount paid or payable by the indemnified party as a result of
any Claim in such proportion as is appropriate to reflect the relative benefits
received by the indemnifying party on the one hand and the indemnified party on
the other from the transactions contemplated by this Note. If, however, the
allocation provided in the immediately preceding sentence is not permitted by
applicable law, or if the indemnified party failed to give the notice required
by subsection (d) above, then each indemnifying party shall contribute to the
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the indemnifying party and the indemnified party as well as any other
relevant equitable considerations. The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The amount paid or
payable in respect of any Claim shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection

                                       24

<PAGE>

with investigating or defending any such Claim. Notwithstanding the foregoing,
no underwriter or controlling person thereof, if any, shall be required to
contribute, in respect of such underwriter's participation as an underwriter in
the offering, any amount in excess of the amount by which the total price at
which the Registrable Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. The obligation of any underwriters to
contribute pursuant to this subsection (e) shall be several in proportion to
their respective underwriting commitments and not joint.

                           (f)      The provisions of subsections (b) through
(e) hereof shall be in addition to any other rights to indemnification or
contribution which any indemnified party may have pursuant to law or contract
and shall remain operative and in full force and effect regardless of any
investigation made or omitted by or on behalf of any indemnified party and shall
survive the transfer of the Registrable Securities by any such party.

                           (g)      If the registration requirements of
subsection (a) above have not been fulfilled, and the registration statement as
filed pursuant to subsection (a) above is not then effective, then Registered
Holders shall have certain "piggy-back" registration rights as set forth in this
subsection (g).

                                    A.       If at any time after the Initial
Closing Date (as defined in the Memorandum), the Issuer shall file with the SEC
a registration statement under the 1933 Act registering any shares of Common
Stock owned by any person or entity, the Issuer shall give written notice to
each Registered Holder thereof prior to such filing.

                                    B.       Within fifteen (15) days after such
notice from the Issuer, each Registered Holder shall give written notice to the
Issuer whether or not the Registered Holder desires to have all of the
Registered Holder's Registrable Securities included in the registration
statement. If a Registered Holder fails to give such notice within such period,
such Registered Holder shall not have the right to have such Registered Holder's
Registrable Securities registered pursuant to such registration statement. If a
Registered Holder gives such notice, then the Issuer shall include such
Registered Holder's Registrable Securities in the registration statement, at the
Issuer's sole cost and expense, subject to the remaining terms of this
subsection (g).

                                    C.       If the registration statement
relates to an underwritten offering, and the underwriter shall determine in
writing that the total number of shares of Common Stock to be included in the
offering, including the Registrable Securities, shall exceed the amount which
the underwriter deems to be appropriate for the offering, the number of shares

                                       25

<PAGE>

of the Registrable Securities shall be reduced in the same proportion as the
remainder of the shares in the offering and each Registered Holder's Registrable
Securities included in such registration statement will be reduced
proportionately. For this purpose, if other securities in the registration
statement are derivative securities, their underlying shares shall be included
in the computation. The Registered Holders shall enter into such agreements as
may be reasonably required by the underwriters and the Registered Holders shall
pay to the underwriters commissions relating to the sale of their respective
Registrable Securities.

                                    D.       The Registered Holders shall have
two (2) opportunities to have the Registrable Securities registered under this
subsection (g).

                                    E.       The Registered Holder shall furnish
in writing to the Issuer such information as the Issuer shall reasonably require
in connection with a registration statement.

                                    F.       The Issuer shall keep the
registration statement filed pursuant to this subsection (g) current and
effective for at least three (3) years from the Final Closing Date, subject to
extension for the number of days by which the filing or effectiveness of the
registration statement is delayed beyond the 60 and 150-day periods contemplated
in subsection (a) of this Supplement A, or until such earlier date as all of the
Registrable Securities registered pursuant to such registration statement shall
have been sold or otherwise transferred.

                           (h)      If and whenever the Issuer is required by
the provisions of this Supplement A to use its best efforts to register any
Registrable Securities under the 1933 Act, the Issuer shall, as expeditiously as
possible under the circumstances:

                                    A.       Prepare and file with the SEC a
registration statement with respect to such Registrable Securities and use its
best efforts to cause such registration statement to become effective as soon as
possible and remain effective.

                                    B.       Prepare and file with the SEC such
amendments and supplements to such registration statement and the prospectus
used in connection therewith as may be necessary to keep such registration
statement current and to comply with the provisions of the 1933 Act, and any
regulations promulgated thereunder, with respect to the sale or disposition of
all Registrable Securities covered by the registration statement required to
effect the distribution of the securities, but in no event shall the Issuer be
required to do so for a period of more than three (3) years following the
effective date of the registration statement.

                                    C.       Furnish to the Sellers
participating in the offering, copies (in reasonable quantities) of summary,
preliminary, final, amended or supplemented prospectuses, in conformity with the
requirements of the 1933 Act and any regulations promulgated thereunder, and
other documents as reasonably may be required in order to facilitate

                                       26

<PAGE>

the disposition of the securities, but only while the Issuer is required under
the provisions hereof to keep the registration statement current.

                                    D.       Use its best efforts to register or
qualify the Registrable Securities covered by such registration statement under
such other securities or blue sky laws of such jurisdictions of the United
States as the Sellers participating in the offering shall reasonably request,
and do any and all other acts and things which may be reasonably necessary to
enable each participating Seller to consummate the disposition of the
Registrable Securities in such jurisdictions.

                                    E.       Notify each Seller selling
Registrable Securities, at any time when a prospectus relating to any such
Registrable Securities covered by such registration statement is required to be
delivered under the 1933 Act, of the Issuer's becoming aware that the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, and promptly prepare and furnish to
each such Seller selling Registrable Securities a reasonable number of copies of
a prospectus supplemented or amended so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
the light of the circumstances then existing.

                                    F.       As soon as practicable after the
effective date of the registration statement, and in any event within eighteen
(18) months thereafter, make generally available to Sellers participating in the
offering an earnings statement (which need not be audited) covering a period of
at least twelve (12) consecutive months beginning after the effective date of
the registration statement which earnings statement shall satisfy the provisions
of Section 11(a) of the 1933 Act, including, at the Issuer's option, Rule 158
thereunder. To the extent that the Issuer files such information with the SEC in
satisfaction of the foregoing, the Issuer need not deliver the above referenced
earnings statement to Seller.

                                    G.       Upon request, deliver promptly to
counsel of each Seller participating in the offering copies of all
correspondence between the SEC and the Issuer, its counsel or auditors and all
memoranda relating to discussions with the SEC or its staff with respect to the
registration statement and permit each such Seller to do such investigation at
such Seller's sole cost and expense, upon reasonable advance notice, with
respect to information contained in or omitted from the registration statement
as it deems reasonably necessary. Each Seller agrees that it will use its best
efforts not to interfere unreasonably with the Issuer's business when conducting
any such investigation and each Seller shall keep any such information received
pursuant to this subsection (h)G confidential.

                                    H.       Provide a transfer agent and
registrar located in the United

                                       27

<PAGE>

States for all such Registrable Securities covered by such registration
statement not later than the effective date of such registration statement.

                                    I.       If required, list the Registrable
Securities covered by such registration statement on such exchanges, NASDAQ,
and/or the OTC Bulletin Board on which the Common Stock is then currently
listed.

                                    J.       Pay all Registration Expenses (as
hereinafter defined) incurred in connection with a registration of Registrable
Securities, whether or not such registration statement shall become effective.
All expenses incurred by the Issuer in complying with this Supplement A,
including, without limitation, all registration and filing fees, printing
expenses, fees and disbursements of counsel and independent public accountants
for the Issuer and all other Persons retained by the Issuer in connection with
such Registration Statement, fees and expenses (including counsel fees) incurred
in connection with complying with state securities or "blue sky" laws, transfer
taxes and fees of transfer agents and registrars, fees and disbursements (in
total not exceeding $10,000) of one counsel, other than the Issuer's counsel,
representing the Holders of all of the Registrable Shares and selected by such
Holders, and fees and disbursements of underwriters customarily paid by the
issuers or sellers of securities, but excluding any Selling Expenses, are called
"Registration Expenses". All underwriting discounts and selling commissions
applicable to the sale of Registrable Shares are called "Selling Expenses". The
Issuer will pay all Registration Expenses in connection with the Registration
Statement. All Selling Expenses in connection with the Registration Statement
shall be borne by the participating sellers in proportion to the number of
shares sold by each, or by such participating sellers other than the Issuer
(except to the extent the Issuer shall be a seller) as they may agree.

                           (i)      The Issuer acknowledges that there is no
adequate remedy at law for failure by it to comply with the provisions of this
Supplement A and that such failure would not be adequately compensable in
damages, and therefore agrees that its agreements contained in this Supplement A
may be specifically enforced. In the event that the Issuer shall fail to file
such registration statement when required pursuant to subsection (a) above or to
keep any registration statement effective as provided in this Supplement A or
otherwise fails to comply with its obligations and agreements in this Supplement
A, then, in addition to any other rights or remedies the Registered Holders may
have at law or in equity, including without limitation, the right of rescission,
the Issuer shall indemnify and hold harmless the Registered Holders from and
against any and all manner or loss which they may incur as a result of such
failure. In addition, the Issuer shall also reimburse the Registered Holders for
any and all reasonable legal fees and expenses incurred by them in enforcing
their rights pursuant to this Supplement A, regardless of whether any litigation
was commenced.
