**SENIOR
      CONVERTIBLE PROMISSORY NOTE**




THIS
      PROMISSORY NOTE IS SUBJECT TO THE PROVISIONS OF A CERTAIN INTERCREDITOR


AGREEMENT
      DATED AS OF SEPTEMBER 27, 2007 AMONG MICHAEL GRANITO, PHRONESIS PARTNERS, L.P.
      AND QUICK-MED TECHNOLOGIES, INC.







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 seventy
      five
      thousand dollars ($375,000.00) (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 Borrower acknowledges it has already
      received proceeds of THREE HUNDRED SEVENTY FIVE THOUSAND DOLLARS ($375,000)
      as
      of July 30, 2007 from Lender and that therefore this is the current Principal
      Amount as of the date of this Note. The following terms shall apply to this
      Promissory Note:




1.  Use
      of
      Proceeds .
      ONE
      HUNDRED TWENTY FIVE THOUSAND DOLLARS ($125,000) are to be used to pay the 12
      month salary for the Borrower’s Chief Executive Officer as approved by its Board
      of Directors on June 14, 2007 and to otherwise fund the operations of the
      Borrower for the next 12 months. Should the Chief Executive Officer unable
      to
      remain in his executive position during the first 12 month period, any remaining
      balance of $125,000 at that time shall be returned to Lender. Lender shall
      have
      no obligations to make an additional funding the Borrower hereunder if the
      total
      principal amount outstanding at any time exceed $375,000.00.




2.  Interest
      Rate .
      Interest shall accrue on the outstanding Principal Amount at the rate of eight
      percent (8%) per annum. The Borrower acknowledges that the principal was loaned
      in six installments, such that the cumulative outstanding Principal Amount
      was
      $143,160 at April 26, 2007, $203,160 at May 1, 2007 (based on $60,000 advance),
      $243,160 at June 1, 2007 (based on $40,000 advance), $253,160 at June 13, 2007
      (based on $10,000 advance), $303,160 at June 25, 2007 (based on $50,000 advance)
      and $375,000 since July 30, 2007 (based on $71,840 advance). 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 July
      13, 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 for the 20 trading days (approximately
      30 calendar days) preceding the date of the Advance, or $0.74 per
      share.




(c)  Mechanics
      of Conversion .




**(i)**  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.




(ii)  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.




(iii)  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.




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
      Lender represents to the Borrower that it has no other outstanding obligations
      and that this Promissory Note shall rank senior to all outstanding obligations
      of the Lender; provided that, this Note shall rank *pari
      passu* with all
      other debt obligations owed to Michael Granito and debt issued concurrently
      with
      this Note to Phronesis Partners LP.




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 require prompt payment when due and payable of all other
      amounts of principal of or interest on this Note or other amounts payable on
      demand, or to exercise any rights and remedies available to it in order to
      collect all such other amounts due and payable under this Note.




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 in connection with
      the
      delivery, acceptance, performance or enforcement of this Note.




18.  Choice
      of Law; Forum Selection; Consent to Jurisdiction .
      This
      Note shall be governed by, construed and interpreted in accordance with the
      laws
      of the State of Florida. The Borrower hereby (a) agrees that all disputes and
      matters 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.




19.  Service
      of Process .
      The
      Borrower hereby consents to process being served in any suit, action or
      proceeding instituted in connection with this Note by the mailing of a copy
      thereof to the Borrower by certified mail, postage prepaid, return receipt
      requested. The Borrower hereby irrevocably agrees that such service shall be
      deemed to be service of process upon the Borrower in any such 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.




20.  Notice .
      Any
      notice, demand, request or other communication which the Lender or the Borrower
      may be required to give hereunder shall be in writing and shall be effective
      when delivered and at the address provided below:

      upon the receipt thereof by the Borrower regardless of the procedure or method
      utilized to accomplish delivery thereof to the Borrower.
