becoming bound by this security agreement (whether as a new debtor, a transferee

agreement) as the debtor and indicating the Collateral. Debtor shall not file a
Correction Statement relating to the Collateral or to any Financing Statement or
Fixture Filing filed by the Bank without the Bank's prior written consent. If
the Debtor is a corporation, limited liability company, limited partnership or
other Registered Organization (as that term is defined in Article 9 of the
Uniform Commercial Code as in effect in Connecticut) the Debtor shall, at its
expense, furnish to Bank a certified copy of Debtor's organization documents
verifying its correct legal name or, at Bank's election, shall permit the Bank
to obtain such certified copy at Debtor's expense. From time to time, at Bank's

property) at all times insured against risks of loss or damage by fire

certificates of such insurance or other evidence satisfactory to the Bank as to
compliance with the provisions of this paragraph. Debtor hereby irrevocably
appoints the Bank to act as attorney-in-fact for the Debtor in making, adjusting
and settling claims under such policies of insurance or endorsing the Debtor's
name on any drafts drawn by insurers of the Collateral or any other documents to
effect collection. Such insurance maintained by the Debtor shall include,
without limitation, insurance coverage on Collateral in the possession of the
Bank or its agent or contractor. Debtor, and any other Obligor by becoming bound
by the Obligations, hereby indemnifies the Bank against any loss or damage to
Collateral not insured by Debtor and for any deficiency in any effective
insurance coverage required to be maintained by Debtor pursuant to this section,
which indemnification obligation shall constitute part of the Obligations.

the Collateral; may place and pay for insurance on the Collateral; may order and
pay for the repair, maintenance and preservation of the Collateral; and may pay
any fees for filing or recording such instruments or documents as may be
necessary or desirable to perfect the security interest granted herein. The
Debtor agrees to reimburse the Bank on demand for any payment made or any
expense incurred by the Bank pursuant to the foregoing authorization, and all
such payments and expenses shall constitute part of the principal amount of
Obligations hereby secured and shall bear inters at the highest rate payable on
the Obligations of the Debtor to the Bank.

security interest, mortgage or encumbrance upon any of its property or assets

agreement related to the Obligations, it will secure the Obligations or cause
them to be secured by any such lien, pledge, security interest, mortgage or
encumbrance equally and ratably with any and all indebtedness thereby secured,
provided, that nothing contained herein shall be construed or interpreted to
permit the Borrower to create, assume or permit to exist any lien, pledge,
security interest, mortgage or encumbrance not otherwise agreed to in writing by
the Bank. In the event that any other security interest or lien attaches to the
Collateral, other than Permitted Liens or the security interest to the Bank,
Debtor hereby grants to Bank a power of attorney to, in the name of the Debtor,
request and to enforce any right of Debtor to obtain, accountings and
information from such other secured party or lienor relating to the obligations
secured and collateral securing such security interest or lien, which power,
being coupled with an interest, shall not be revocable by Debtor. Debtor agrees
to pay or reimburse Bank upon demand for any charges resulting from such
requests for information.

(k) If any part of the Collateral is a Fixture, the Debtor will, on demand,
furnish the Bank with a disclaimer or release signed by all persons having an
interest in the real estate or any interest in the Collateral which is recorded
or filed, or which may be, prior to the Bank's interest.

in this Agreement or in any supporting or supplemental documentation or
statement are, will be, and shall continue to be true and correct in all
material respects.

satisfactory to the Bank), either: (i) cause a Document of title, in form and
content satisfactory to the Bank, to be issued in the name of the Bank or (ii)

holding such Collateral for the benefit of the Bank.

Collateral ceases to be such Inventory; and (ii) not cause or permit a
Certificate of Title to be issued in another state which does not list the
Bank's security interest.

by the Debtor, of the brief details of the Commercial Tort Claim and shall grant

of the Obligations shall, at the option of the Bank or automatically, as the
case may be as provided in the instrument or agreement evidencing the defaulted
Obligations, without demand, notice or legal process of any kind, accelerate and
become immediately due and payable.

Upon and after an Event of Default, the Bank shall have the following additional
rights and remedies (which the Debtor , and, by becoming bound by the
Obligations or this Agreement, all other Obligors, Guarantors and any New
Debtors accept and agree upon):

(a) All of the rights and remedies of a secured party under the Uniform
Commercial Code or any other applicable law or at equity, all of which rights
and remedies shall be cumulative and non-exclusive, to the extent permitted by
law, in addition to any other rights and remedies contained in this Security
Agreement or in any other agreement, document or instrument evidencing,
governing or securing the Obligations.

(b) The right to (i) take possession of the Collateral, without resort to legal
process and without prior notice to Debtor, and for the purpose Debtor hereby
irrevocably appoints the Bank its attorney-in-fact to enter upon any premises on
which the Collateral or any part thereof may be situated and remove the
Collateral therefrom, (ii) require the Debtor to assemble the Collateral and
make it available to Bank in a place to be designated by the Bank, in its sole
discretion, or

                                        9
<PAGE>

(iii) the right to locate, disable or to take possession of the Collateral by
electronic, digital, magnetic or wireless optical electromagnetic or similar
means after giving any notices required under applicable law. The Debtor shall
make available to the Bank all premises, locations and facilities necessary for
the Bank's taking possession of the Collateral or for removing or putting the
Collateral in saleable form.

(c) The right to sell or otherwise dispose of all or any part of the Collateral
by public or private sale or sales. Unless the Collateral is perishable or
threatens to decline speedily in value or is of a type customarily sold on a
recognized market, the Bank will give the Debtor at least five (5) days prior
written notice of the time and place of any public sale thereof or of the time
after which any private sale or any other intended disposition (which may
include, without limitation, a public sale or lease of a all or part of the
Collateral) is to be made. The Debtor agrees that 5 days is a reasonable time
for such notice. The Bank, its employees, attorneys and agents may bid and
become purchasers at any such sale, if public, and may purchase at any private
sale of the Collateral that is of a type customarily sold on a recognized market
or which is subject to widely distributed standard price quotations. A public or
private sale of the Collateral or any portion thereof may be accomplished by
digital or electronic means, such as through use of the internet or other
telecommunications means.

At any public or private sale the Collateral shall be sold "as is" with no
warranties by the Bank, whether express or implied. Any public or private sale
shall be free from any right of redemption which the Debtor waives and releases
and which Debtor and any Guarantors agree that they will confirm in a separate
written agreement after any default. If there is a deficiency after such sale
and the application of the net proceeds from such sale, the Debtor shall be
responsible for the same, with interest at the maximum rate allowable by law,
and the costs and expenses of collection of such deficiency, including without
limitation, attorney's fees.

the Debtor for this purpose, such appointment being coupled with an interest),
without prior notice to Debtor and without resort to legal process, to notify
the persons liable for payment of the Accounts, Chattel Paper, Instruments and
General Intangibles at any time and direct such persons to make payments
directly to the Bank, and to perform all acts the Debtor could take to collect
on such Accounts, Chattel Paper, Instruments and General Intangibles, including,

    SENIOR CONVERTIBLE
PROMISSORY NOTE 2

     

    FOR VALUE
RECEIVED, the undersigned, QUICK-MED TECHNOLOGIES, INC. (the “Borrower”),
promises unconditionally to pay to the order of Michael Granito, his successors
or assigns (the “Lender”) at the Lender’s offices at 1088 Shady Avenue,
Pittsburgh, Pennsylvania 15232, or at such other place as the Lender may from
time to time designate, the principal amount of up to three hundred thousand
dollars ($300,000.00) (the “Principal Amount”) or so much thereof as is
disbursed to Borrower pursuant to this Note, together with interest on the
unpaid Principal Amount outstanding from time to time at the rate or rates
hereafter specified and any and all other sums which may be owing to the Lender
by the Borrower pursuant to this Note.   The following terms
shall apply to this Promissory Note:

     

    1. Receipts of
Funds.  Borrower acknowledges that it received Fifty Thousand
Dollars ($50,000) each (the “Advance”) on the following dates – October 30,
2007, November 29, 2007, December 13, 2007, December 27, 2007, January 14, 2008,
and January 30, 2008.   Lender shall have no obligations to make
an additional funding the Borrower hereunder if the total principal amount
outstanding at any time exceed $300,000.00.

     

    2. Interest
Rate.  Interest shall accrue on the outstanding Principal
Amount at the rate of eight percent (8%) per annum.  Interest shall be
calculated on the basis of a year of three hundred sixty five (365) days applied
to the actual days on which there exists an unpaid balance under this
Note.

     

    3. Interest
Payments.  The Borrower shall pay accrued and unpaid interest
on the Maturity Date, as the case may be and as hereinafter defined, and
thereafter on demand until all sums due under this Note, whether principal,
interest, or other sums, have been paid in full.

     

    4. Principal.  Unless
sooner paid or converted, the entire outstanding Principal Amount as well as all
other sums under this Note that remain unpaid shall be due and payable on
October 29, 2010 (the “Maturity Date”); provided that, the Borrower shall make
amortized payments on the outstanding principal plus interest during the term of
this Note depending on the free cash flow from operations in excess of
anticipated cost from operations as determined in the discretion of the
Borrower’s Board of Directors.

     

    5. Prepayment.  Borrower
may prepay any portion of the outstanding principal amount of this Promissory
Note with 30 days prior written notice.

     

    6. Conversion.  This
Note shall be convertible into shares of Common Stock of the Borrower, on the
terms and conditions set forth in this Section 6.

    (a)  Conversion
Right.  Subject to the provisions of Section 6(d), at any time
or times on or after the first date of this Note, the Lender shall be entitled
to convert any portion of the outstanding and unpaid Conversion Amount (as
defined below) into validly issued, fully paid and nonassessable shares of
Common Stock in accordance with Section 7(c), at the Conversion Rate (as defined
below).

     

              (b) Conversion
Rate.  The number of shares of Common Stock issuable upon
conversion of any Conversion Amount pursuant to Section 6(a) shall be determined
by dividing (x) such Conversion Amount by (y) the Conversion Price (the
“Conversion Rate”).

     

                    (i) “Conversion
Amount” means the portion of the Principal and interest to be converted,
redeemed or otherwise with respect to which this determination is being
made.

     

                    (ii) “Conversion
Price” means, as of any Conversion Date (as defined below), the closing price
per share of the Borrower’s common stock at the date each Advance is
received.

     

     

    

      
        
           

        

        
          -1-

          
            

          

        

         

      

    

     

                     (iii) Mechanics of
Conversion.

     

                    (iv) Optional
Conversion.  To convert any Conversion Amount into shares of
Common Stock on any date (a “Conversion Date”), the Lender shall (A) transmit by
facsimile (or otherwise deliver), for receipt on or prior to 5:00 p.m., Pacific
Time, on such date, a copy of an executed notice of conversion in the form
attached hereto as Exhibit A (the
“Conversion Notice”) to the Borrower and (B) if required by Section 6(c)(iii),
surrender this Note to a common carrier for delivery to the Borrower as soon as
practicable on or following such date (or an indemnification undertaking with
respect to this Note in the case of its loss, theft or
destruction).  The Borrower shall transmit by facsimile a confirmation
of receipt of such Conversion Notice to the Lender and the Borrower’s transfer
agent, (the “Transfer Agent”).  The Transfer Agent shall issue and
deliver to the address as specified in the Conversion Notice, a certificate or
certificates, registered in the name of the Lender or its designee, for the
number of shares of Common Stock to which the Lender shall be
entitled.  If this Note is physically surrendered for conversion as
required by Section 6(c)(iii) and the outstanding Principal of this Note is
greater than the Principal portion of the Conversion Amount being converted,
then the Borrower shall as soon as practicable and in no event later than ten
(10) Business Days after receipt of this Note and at its own expense, issue and
deliver to the holder a new Note (in accordance with Section 15(d)) representing
the outstanding Principal not converted.  The Person or Persons
entitled to receive the shares of Common Stock issuable upon a conversion of
this Note shall be treated for all purposes as the record holder or holders of
such shares of Common Stock on the Conversion Date.

     

                    (v) Book-Entry.  Notwithstanding
anything to the contrary set forth herein, upon conversion of any portion of
this Note in accordance with the terms hereof, the Lender shall not be required
to physically surrender this Note to the Borrower unless (A) the full Conversion
Amount represented by this Note is being converted or (B) the Lender has
provided the Borrower with prior written notice (which notice may be included in
a Conversion Notice) requesting physical surrender and reissue of this
Note.  The Lender and the Borrower shall maintain records showing the
Principal converted and the dates of such conversions or shall use such other
method, reasonably satisfactory to the Lender and the Borrower, so as not to
require physical surrender of this Note upon conversion.

     

                    (vi) Legend.  The
Converted Shares shall bear a legend that reads:

     

    THE
SECURITIES EVIDENCED BY THIS STOCK CERTIFICATE MAY NOT BE OFFERED FOR SALE,
SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE
REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT
REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

     

    7. Adjustment.  If
the Borrower at any time on or after the date of this Note subdivides (by any
stock split, stock dividend, recapitalization or otherwise) one or more classes
of its outstanding shares of Common Stock into a greater number of shares, the
Conversion Price in effect immediately prior to such subdivision will be
proportionately reduced.  If the Borrower at any time on or after the
Closing Date combines (by combination, reverse stock split or otherwise) one or
more classes of its outstanding shares of Common Stock into a smaller number of
shares, the Conversion Price in effect immediately prior to such combination
will be proportionately increased..

     

    8. Negative Covenants.
During the term of this Promissory Note and until all obligations hereunder are
satisfied,  Borrower shall not, without first obtaining the
affirmative written consent of the Lender, which shall not be unreasonably
withheld: (i) pay or declare any dividend or distribution on any common
stock or preferred stock (“Capital Stock”), or apply any of its assets to the
redemption, purchase or acquisition, directly or indirectly, through
subsidiaries or otherwise, of any share capital or assets of another entity;
(ii)  sell, transfer, lease, offer as collateral or otherwise dispose
of any of its Capital Stock, assets or properties other than in the ordinary
course of business transactions or as unanimously approved by the Board of
Directors; (iii)  enter into any  joint venture, business
combination, merger, consolidation, recapitalization or other
reorganization or permit any subsidiary to enter into any merger, consolidation,
recapitalization or other reorganization; (iv) enter into any agreement, or
allow any subsidiary, to enter any agreement to issue or offer any security,
including, without limitation, any equity security, convertible note, secured
note or promissory note and (v)  amend or repeal any provision of, or add
any provision to, the Borrower's certificate of incorporation or by-laws other
than for subject matters not involving the items subject to Lender’s prior
written consent listed above;
provided however, Lender shall not be obligated to provide affirmative written
consent, if in Lender’s reasonable opinion, consent to any of the foregoing
actions would: (a) impair Lender’s ability to be repaid under this Promissory
Note or (b) impair Borrower’s ability to perform its obligations under the Share
Exchange Agreement.

     

    

      
        
           

        

        
          -2-

          
            

          

        

         

      

    

     

    9. Repayment
Extension.  If any payment of principal or interest shall be
due on a Saturday, Sunday or any other day on which banking institutions in the
State of Florida are required or permitted to be closed, such payment shall be
made on the next succeeding business day and such extension of time shall be
included in computing interest under this Note.

     

    10. Manner and Application of
Payments.  All payments due hereunder shall be paid in lawful
money of the United States of America which shall be legal tender in payment of
all debts and dues, public and private, in immediately available funds, without
offset, deduction or recoupment. Any payment by check or draft shall be subject
to the condition that any receipt issued therefore shall be ineffective unless
the amount due is actually received by the Lender.

     

    11. Collateral; Security
Interest.  The Borrower hereby grants to the Lender as
collateral security for its obligations hereunder a security interest in and to
all right, title and interest of the Borrower in and to all of the Borrower’s
personal property assets of each and every type more specifically identified in
Article 9 of the Uniform Commercial Code as in effect in the State of Florida,
whether now owned or hereafter acquired, wherever located.  The Lender
is hereby authorized to file a financing statement naming the Borrower, as
debtor, and the Lender, as secured party, in respect of all such
collateral.  Lender’s interest in the collateral security shall be
limited to the outstanding principal and interest under the
Note.  Notwithstanding the foregoing, the Lender shall not
unreasonably withhold the Borrower’s request to restructure the security
interest in case of a future debt or equity financing.

     

    12. No Other Outstanding
Notes. The Borrower represents to the Lender that it has no other
outstanding obligations, of which the Lender is unaware, and that this
Promissory Note shall rank senior to all outstanding obligations of the Lender,
unless previously agreed by the Lender; this Note shall rank pari passu with all senior
debt obligations owed to Michael Granito.

     

    13. Events of
Default.  The occurrence of any one or more of the following
events shall constitute an “Event of Default” under this Note:

     

    (a) the
failure of the Borrower to pay any sum due under this Note within three (3) days
after such payment was first due, whether by demand or otherwise;

     

    (b) the
occurrence or commencement of a liquidation or bankruptcy or similar proceeding
in respect of the Borrower or any of its assets and;

     

    (c) the
breach by Lender of any of the Negative Covenants set forth in Section 9 of this
Promissory Note.

     

    14. Rights and Remedies Upon
Default.  Upon the occurrence of an Event of Default hereunder,
the Lender, in the Lender’s sole discretion and without notice to the Borrower
may:

     

    (a)
declare the entire outstanding Principal Amount, together with all accrued
interest and all other sums due under this Note to be immediately due and
payable, and the same shall thereupon become immediately due and payable without
presentment, demand or notice which are hereby expressly waived; (b) exercise
its right of setoff against any money, funds, credits or other property of any
nature whatsoever of the Borrower now or at any time hereafter in the possession
of, in transit to or from, under the control or custody of, or on deposit with,
the Lender in any capacity whatsoever, including without limitation, any balance
of any deposit account and any credits with the Lender; (c) terminate any
outstanding commitments of the Lender to the Borrower; (d) exercise all rights
and remedies of a secured party in respect of the collateral referred to above
as provided under Article 9 of the Uniform Commercial Code as in effect on the
date hereof in the State of Florida; and (e) exercise any or all rights, powers,
and remedies now or hereafter existing at law, in equity, by statute or
otherwise.

     

    15. Remedies
Cumulative.  Each right, power and remedy of the Lender
hereunder, or now or hereafter existing at law, in equity, by statute or
otherwise shall be cumulative and concurrent, and the exercise or beginning of
the exercise of any one or more of them shall not preclude the simultaneous or
later exercise by the Lender of any or all such other rights, powers or
remedies. No failure or delay by the Lender to insist upon the strict
performance of any one or more provisions of this Note or to exercise any right,
power or remedy consequent upon a breach thereof or default hereunder shall
constitute a waiver thereof or preclude the Lender from exercising any such
right, power or remedy. By accepting full or partial payment after the due date
of any amount of principal of or interest on this Note, or other amounts payable
on demand, the Lender shall not be deemed to have waived the right either to

    16. Maximum Rate of
Interest.  Notwithstanding any provision of this Note to the
contrary, the Borrower shall not be obligated to pay interest pursuant to this
Note in excess of the maximum rate of interest permitted by the laws of any
state determined to govern this Note or the laws of the United States applicable
to loans in such state. If any provisions of this Note shall ever be construed
to require the payment of any amount of interest in excess of that permitted by
applicable law, then the interest to be paid pursuant to this Note shall be held
subject to reduction to the amount allowed under applicable law and any sums
paid in excess of the interest rate allowed by law shall be applied in reduction
of the principal balance outstanding pursuant to this Note.  The
Borrower acknowledges that it has been contemplated at all times by the Borrower
that the laws of the State of Florida will govern the maximum rate of interest
that it is permissible for the Lender to charge the Borrower pursuant to this
Note.

     

    17. Waiver of
Presentment.  The Borrower waives demand, presentment, protest,
and notice of demand, of non-payment, of dishonor, protest and all other demands

Note.

     

    18. Choice of Law; Forum
Selection; Consent to Jurisdiction.  This Note shall be

whatsoever arising under, in connection with, or incident to this Note shall be
litigated, if at all, in and before a court located in the State of Florida to
the exclusion of the courts of any other state or country and (b) irrevocably
submits to the non-exclusive jurisdiction of any Florida court or federal court
sitting in the State of Florida in any action or proceeding arising out of or
relating to this Note, and hereby irrevocably waives any objection to the laying
of venue of any such action or proceeding in any such court and any claim that
any such action or proceeding has been brought in an inconvenient forum. A final
judgment in any such action or proceeding shall be conclusive and may be
enforced in any other jurisdiction by suit on the judgment or in any other
manner provided by law.

suit, action or proceeding. Nothing in this Note shall affect the right of the
Lender to serve process in any other manner otherwise permitted by law, and
nothing in this Note will limit the right of the Lender otherwise to bring
proceedings against the Borrower in the courts of any other jurisdiction or
jurisdictions.
