    COMMON
      STOCK, PAR VALUE $0.01 PER SHARE

    

    For
      VALUE
      RECEIVED, ____________________ (“Warrantholder”), is entitled to purchase,
      subject to the provisions of this Warrant, from Precision Optics Corporation,
      Inc., a Massachusetts corporation (“Company”), at any time from and after the
      Amendment Effective Date and not later than 5:00 P.M., Eastern time, on the
      Expiration Date (as defined above), at an exercise price per share equal to
      $0.07 (the exercise price in effect being herein called the “Warrant Price”),
      ______ shares (“Warrant Shares”) of the Company’s Common Stock, par value $0.01
      per share (“Common Stock”). The number of Warrant Shares purchasable upon
      exercise of this Warrant and the Warrant Price shall be subject to adjustment
      from time to time as described herein. This Warrant is being issued pursuant
      to
      the Purchase Agreement, dated as of June 25, 2008 (the “Purchase Agreement”),
      among the Company and the initial holders of the Company Warrants (as defined
      below). Capitalized terms used herein have the respective meanings ascribed
      thereto in the Purchase Agreement unless otherwise defined herein.

    

    Section
      1. Registration.
      The
      Company shall maintain books for the transfer and registration of the Warrant.
      Upon the initial issuance of this Warrant, the Company shall issue and register
      the Warrant in the name of the Warrantholder.

    

    Section
      2. Transfers.
      As
      provided herein, this Warrant may be transferred only pursuant to a registration
      statement filed under the Securities Act of 1933, as amended (the “Securities
      Act”), or an exemption from such registration. Subject to such restrictions, the
      Company shall transfer this Warrant from time to time upon the books to be
      maintained by the Company for that purpose, upon surrender hereof for transfer,
      properly endorsed or accompanied by appropriate instructions for transfer and
      such other documents as may be reasonably required by the Company, including,
      if
      required by the Company, an opinion of its counsel reasonably satisfactory
      to
      the Company to the effect that such transfer is exempt from the registration
      requirements of the Securities Act, to establish that such transfer is being
      made in accordance with the terms hereof, and a new Warrant shall be issued
      to
      the transferee and the surrendered Warrant shall be canceled by the
      Company.

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    Section
      3. Exercise
      of Warrant.
      This
      Warrant shall not be exercisable prior to the Amendment Effective Date. Subject
      to the provisions hereof, the Warrantholder may exercise this Warrant, in whole
      or in part, at any time from and after the Amendment Effective Date and prior
      to
      its expiration upon surrender of the Warrant, together with delivery of a duly
      executed Warrant exercise form, in the form attached hereto as Appendix A (the
      “Exercise Agreement”) and payment by cash, certified check or wire transfer of
      funds (or
      by
      cashless exercise as provided below) of
      the
      aggregate Warrant Price for that number of Warrant Shares then being purchased,
      to the Company during normal business hours on any business day at the Company’s
      principal executive offices (or such other office or agency of the Company
      as it
      may designate by notice to the Warrantholder). The Warrant Shares so purchased
      shall be deemed to be issued to the Warrantholder or the Warrantholder’s
      designee, as the record owner of such shares, as of the close of business on
      the
      date on which this Warrant shall have been surrendered (or the date evidence
      of
      loss, theft or destruction thereof and security or indemnity satisfactory to
      the
      Company has been provided to the Company), the Warrant Price shall have been
      paid and the completed Exercise Agreement shall have been delivered.
      Certificates for the Warrant Shares so purchased shall be delivered to the
      Warrantholder within a reasonable time, not exceeding three (3) business days,
      after this Warrant shall have been so exercised. The certificates so delivered
      shall be in such denominations as may be requested by the Warrantholder and
      shall be registered in the name of the Warrantholder or such other name as
      shall
      be designated by the Warrantholder, as specified in the Exercise Agreement.
      If
      this Warrant shall have been exercised only in part, then, unless this Warrant
      has expired, the Company shall, at its expense, at the time of delivery of
      such
      certificates, deliver to the Warrantholder a new Warrant representing the right
      to purchase the number of shares with respect to which this Warrant shall not
      then have been exercised. As used herein, “business day” means a day, other than
      a Saturday or Sunday, on which banks in New York City are open for the general
      transaction of business. Each exercise hereof shall constitute the
      re-affirmation by the Warrantholder that the representations and warranties
      contained in Section 5 of the Purchase Agreement are true and correct in all
      material respects with respect to the Warrantholder as of the time of such
      exercise.

    

    If
      (1) a
      certificate representing the Warrant Shares is not delivered to the
      Warrantholder within three (3) Business Days of the due exercise of this Warrant
      by the Warrantholder and (2) prior to the time such certificate is received
      by
      the Warrantholder, the Warrantholder, or any third party on behalf of the
      Warrantholder or for the Warrantholder’s account, purchases (in an open market
      transaction or otherwise) shares of Common Stock to deliver in satisfaction
      of a
      sale by the Warrantholder of shares represented by such certificate (a
“Buy-In”), then the Company shall pay in cash to the Warrantholder (for costs
      incurred either directly by such Warrantholder or on behalf of a third party)
      the amount by which the total purchase price paid for Common Stock as a result
      of the Buy-In (including brokerage commissions, if any) exceeds the proceeds
      received by such Warrantholder as a result of the sale to which such Buy-In
      relates. The Warrantholder shall provide the Company written notice indicating
      the amounts payable to the Warrantholder in respect of the
      Buy-In.

    In
      the
      event that a Change of Control (as defined in the Note) occurs prior to the
      Amendment Effective Date, the Company shall redeem as of the effective time
      of
      the Change of Control (the “Redemption Date”) this Warrant at a cash redemption
      price equal to the product of (i) the number of shares of Common Stock into
      which this Warrant would have been exercisable if the Warrant was fully
      exercisable on the Redemption Date and (ii) the amount, if any, by which the
      Fair Market Value of the consideration per share to be received by holders
      of
      Common Stock in connection with such Change of Control as of the Redemption
      Date
      exceeds the Warrant Price in effect immediately prior to the effective time
      of
      the Change of Control. For purposes of determining such “Fair Market Value”, (i)
      publicly traded securities shall be deemed to have a Fair Market Value equal
      to
      their Market Price, and (ii) any other securities or other assets shall be
      deemed to have a Fair Market Value equal to the fair market value thereof as
      determined by the Board in the good faith exercise of its reasonable business
      judgment. The Company shall provide written notice to the Warrantholder of
      any
      pending Change of Control not less than 15 days prior to the effective date
      of
      such Change of Control, which notice shall include the Company’s estimate of the
      Redemption Price. On the Redemption Date, the Company shall pay the Redemption
      Price to the Warrantholder in immediately available funds to an account
      previously specified in writing by the Warrantholder. The Warrantholder shall
      not be required to surrender this Warrant prior to payment of the Redemption
      Price. Upon the indefeasible payment in full of the Redemption Price to the
      Warrantholder as provided in this Section 3, this Warrant shall be deemed to
      have been extinguished and shall no longer be outstanding for any
      purpose.

    

    Section
      4. Compliance
      with the Securities Act of 1933.
      Except
      as provided in the Purchase Agreement, the Company may cause the legend set
      forth on the first page of this Warrant to be set forth on each Warrant, and
      a
      similar legend on any security issued or issuable upon exercise of this Warrant,
      unless counsel for the Company is of the opinion as to any such security that
      such legend is unnecessary.

    

    Section
      5. Payment
      of Taxes.
      The
      Company will pay any documentary stamp taxes attributable to the initial
      issuance of Warrant Shares issuable upon the exercise of the Warrant; provided,
      however, that the Company shall not be required to pay any tax or taxes which
      may be payable in respect of any transfer involved in the issuance or delivery
      of any certificates for Warrant Shares in a name other than that of the
      Warrantholder in respect of which such shares are issued, and in such case,
      the
      Company shall not be required to issue or deliver any certificate for Warrant
      Shares or any Warrant until the person requesting the same has paid to the
      Company the amount of such tax or has established to the Company’s reasonable
      satisfaction that such tax has been paid. The Warrantholder shall be responsible
      for income taxes due under federal, state or other law, if any such tax is
      due.

    

    Section
      6. Mutilated
      or Missing Warrants.
      In case
      this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall
      issue in exchange and substitution of and upon surrender and cancellation of
      the
      mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen
      or destroyed, a new Warrant of like tenor and for the purchase of a like number
      of Warrant Shares, but only upon receipt of evidence reasonably satisfactory
      to
      the Company of such loss, theft or destruction of the Warrant, and with respect
      to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with
      respect thereto, if requested by the Company.

    Section
      7. Reservation
      of Common Stock.
      The
      Company hereby represents and warrants that, from and after the Amendment
      Effective Date, there will have been reserved, and, from and after the Amendment
      Effective Date, the Company shall at all applicable times keep reserved until
      issued (if necessary) as contemplated by this Section 7, out of the authorized
      and unissued shares of Common Stock, sufficient shares to provide for the
      exercise of the rights of purchase represented by this Warrant. The Company
      agrees that all Warrant Shares issued upon due exercise of the Warrant shall
      be,
      at the time of delivery of the certificates for such Warrant Shares, duly
      authorized, validly issued, fully paid and non-assessable shares of Common
      Stock
      of the Company.

    

    Section
      8. Adjustments.
      Subject
      and pursuant to the provisions of this Section 8, the Warrant Price and number
      of Warrant Shares subject to this Warrant shall be subject to adjustment from
      time to time as set forth hereinafter.

    

    (a) If
      the
      Company shall, at any time or from time to time while this Warrant is
      outstanding, pay a dividend or make a distribution on its Common Stock in shares
      of Common Stock, subdivide its outstanding shares of Common Stock into a greater
      number of shares or combine its outstanding shares of Common Stock into a
      smaller number of shares or issue by reclassification of its outstanding shares
      of Common Stock any shares of its capital stock (including any such
      reclassification in connection with a consolidation or merger in which the
      Company is the continuing corporation), then (i) the Warrant Price in effect
      immediately prior to the date on which such change shall become effective shall
      be adjusted by multiplying such Warrant Price by a fraction, the numerator
      of
      which shall be the number of shares of Common Stock outstanding immediately
      prior to such change and the denominator of which shall be the number of shares
      of Common Stock outstanding immediately after giving effect to such change
      and
      (ii) the number of Warrant Shares purchasable upon exercise of this Warrant
      shall be adjusted by multiplying the number of Warrant Shares purchasable upon
      exercise of this Warrant immediately prior to the date on which such change
      shall become effective by a fraction, the numerator of which is shall be the
      Warrant Price in effect immediately prior to the date on which such change
      shall
      become effective and the denominator of which shall be the Warrant Price in
      effect immediately after giving effect to such change, calculated in accordance
      with clause (i) above. Such adjustments shall be made successively whenever
      any
      event listed above shall occur.

    

    (b) If
      any
      capital reorganization, reclassification of the capital stock of the Company,
      consolidation or merger of the Company with another corporation in which the
      Company is not the survivor, or sale, transfer or other disposition of all
      or
      substantially all of the Company’s assets to another corporation shall be
      effected, then, as a condition of such reorganization, reclassification,
      consolidation, merger, sale, transfer or other disposition, lawful and adequate
      provision shall be made whereby each Warrantholder shall thereafter have the
      right to purchase and receive upon the basis and upon the terms and conditions
      herein specified and in lieu of the Warrant Shares immediately theretofore
      issuable upon exercise of the Warrant, such shares of stock, securities or
      assets as would have been issuable or payable with respect to or in exchange
      for
      a number of Warrant Shares equal to the number of Warrant Shares immediately
      theretofore issuable upon exercise of the Warrant, had such reorganization,
      reclassification, consolidation, merger, sale, transfer or other disposition
      not
      taken place, and in any such case appropriate provision shall be made with
      respect to the rights and interests of each Warrantholder to the end that the
      provisions hereof (including, without limitation, provision for adjustment
      of
      the Warrant Price) shall thereafter be applicable, as nearly equivalent as
      may
      be practicable in relation to any shares of stock, securities or assets
      thereafter deliverable upon the exercise hereof. The Company shall not effect
      any such consolidation, merger, sale, transfer or other disposition unless
      prior
      to or simultaneously with the consummation thereof the successor corporation
      (if
      other than the Company) resulting from such consolidation or merger, or the
      corporation purchasing or otherwise acquiring such assets or other appropriate
      corporation or entity shall assume the obligation to deliver to the
      Warrantholder, at the last address of the Warrantholder appearing on the books
      of the Company, such shares of stock, securities or assets as, in accordance
      with the foregoing provisions, the Warrantholder may be entitled to purchase,
      and the other obligations under this Warrant. The provisions of this paragraph
      (b) shall similarly apply to successive reorganizations, reclassifications,
      consolidations, mergers, sales, transfers or other
      dispositions.

    
      
        
        

      

      
        -4-

        
          

        

      

      
        
        

      

    

    (c) In
      case
      the Company shall fix a payment date for the making of a distribution to all
      holders of Common Stock (including any such distribution made in connection
      with
      a consolidation or merger in which the Company is the continuing corporation)
      of
      evidences of indebtedness or assets (other than cash dividends or cash
      distributions payable out of consolidated earnings or earned surplus or
      dividends or distributions referred to in Section 8(a)), or subscription rights
      or warrants, the Warrant Price to be in effect after such payment date shall
      be
      determined by multiplying the Warrant Price in effect immediately prior to
      such
      payment date by a fraction, the numerator of which shall be the total number
      of
      shares of Common Stock outstanding multiplied by the Market Price (as defined
      below) per share of Common Stock immediately prior to such payment date, less
      the fair market value (as determined by the Company’s Board of Directors in good
      faith) of said assets or evidences of indebtedness so distributed, or of such
      subscription rights or warrants, and the denominator of which shall be the
      total
      number of shares of Common Stock outstanding multiplied by such Market Price
      per
      share of Common Stock immediately prior to such payment date. “Market Price” as
      of a particular date (the “Valuation Date”) shall mean the following: (a) if the
      Common Stock is then listed on the Nasdaq Global Market or the Nasdaq Capital
      Market (“Nasdaq”) or any other national stock exchange, the closing sale price
      of one share of Common Stock on such exchange on the last trading day prior
      to
      the Valuation Date; (b) if the Common Stock is then quoted on the National
      Association of Securities Dealers, Inc. OTC Bulletin Board (the “Bulletin
      Board”) or such similar quotation system or association, the closing sale price
      of one share of Common Stock on the Bulletin Board or such other quotation
      system or association on the last trading day prior to the Valuation Date or,
      if
      no such closing sale price is available, the average of the high bid and the
      low
      asked price quoted thereon on the last trading day prior to the Valuation Date;
      or (c) if the Common Stock is not then listed on a national stock exchange
      or
      quoted on the Bulletin Board or such other quotation system or association,
      the
      fair market value of one share of Common Stock as of the Valuation Date, as
      determined in good faith by the Board of Directors of the Company and the
      Warrantholder. If the Common Stock is not then listed on a national securities
      exchange, the Bulletin Board or such other quotation system or association,
      the
      Board of Directors of the Company shall respond promptly, in writing, to an
      inquiry by the Warrantholder prior to the exercise hereunder as to the fair
      market value of a share of Common Stock as determined by the Board of Directors
      of the Company. In the event that the Board of Directors of the Company and
      the
      Warrantholder are unable to agree upon the fair market value in respect of
      subpart (c) of this paragraph, the Company and the Warrantholder shall jointly
      select an appraiser, who is experienced in such matters. The decision of such
      appraiser shall be final and conclusive, and the cost of such appraiser shall
      be
      borne equally by the Company and the Warrantholder. Such adjustment shall be
      made successively whenever such a payment date is fixed.

    
      
        
        

      

      
        -5-

        
          

        

      

      
        
        

      

    

     

    (d) An
      adjustment to the Warrant Price shall become effective immediately after the
      payment date in the case of each dividend or distribution and immediately after
      the effective date of each other event which requires an
      adjustment.

    

    (e) In
      the
      event that, as a result of an adjustment made pursuant to this Section 8, the
      Warrantholder shall become entitled to receive any shares of capital stock
      of
      the Company other than shares of Common Stock, the number of such other shares
      so receivable upon exercise of this Warrant shall be subject thereafter to
      adjustment from time to time in a manner and on terms as nearly equivalent
      as
      practicable to the provisions with respect to the Warrant Shares contained
      in
      this Warrant.

    

    (f) Except
      as
      provided in subsection (g) hereof, if and whenever the Company shall issue
      or
      sell, or is, in accordance with any of subsections (f)(l) through (f)(7) hereof,
      deemed to have issued or sold, any Additional Shares of Common Stock for no
      consideration or for a consideration per share less than the Warrant Price
      in
      effect immediately prior to the time of such issue or sale, then and in each
      such case (a “Trigger Issuance”) the then-existing Warrant Price, shall be
      reduced, as of the close of business on the effective date of the Trigger
      Issuance, to a price determined as follows:

    

    
      	
              Adjusted Warrant Price = 

            	
              (A
                x B) + D

            
	 	
                    
                A+C

            

    

    

    where

    

    “A”
      equals the number of shares of Common Stock outstanding, including Additional
      Shares of Common Stock (as defined below) deemed to be issued hereunder,
      immediately preceding such Trigger Issuance (but excluding the Additional Shares
      included in “C” below);

    

    “B”
      equals the Warrant Price in effect immediately preceding such Trigger
      Issuance;

    

    “C”
      equals the number of Additional Shares of Common Stock issued or deemed issued
      hereunder as a result of the Trigger Issuance; and

    
      
        
        

      

      
        -6-

        
          

        

      

      
        
        

      

    

    

    “D”
      equals the aggregate consideration, if any, received or deemed to be received
      by
      the Company upon such Trigger Issuance;

    

    provided,
      however, that in no event shall the Warrant Price after giving effect to such
      Trigger Issuance be greater than the Warrant Price in effect prior to such
      Trigger Issuance.

    

    For
      purposes of this subsection (f), “Additional Shares of Common Stock” shall mean
      all shares of Common Stock issued by the Company or deemed to be issued pursuant
      to this subsection (f), other than Excluded Issuances (as defined in subsection
      (g) hereof).

    

    For
      purposes of this subsection (f), the following subsections (f)(l) to (f)(7)
      shall also be applicable:

    

    (f)(1)
      Issuance of Rights or Options. In case at any time the Company shall in any
      manner grant (directly and not by assumption in a merger or otherwise) any
      warrants or other rights to subscribe for or to purchase, or any options for
      the
      purchase of, Common Stock or any stock or security convertible into or
      exchangeable for Common Stock (such warrants, rights or options being called
      “Options” and such convertible or exchangeable stock or securities being called
“Convertible Securities”) whether or not such Options or the right to convert or
      exchange any such Convertible Securities are immediately exercisable, and the
      price per share for which Common Stock is issuable upon the exercise of such
      Options or upon the conversion or exchange of such Convertible Securities
      (determined by dividing (i) the sum (which sum shall constitute the applicable
      consideration) of (x) the total amount, if any, received or receivable by the
      Company as consideration for the granting of such Options, plus (y) the
      aggregate amount of additional consideration payable to the Company upon the
      exercise of all such Options, plus (z), in the case of such Options which relate
      to Convertible Securities, the aggregate amount of additional consideration,
      if
      any, payable upon the issue or sale of such Convertible Securities and upon
      the
      conversion or exchange thereof, by (ii) the total maximum number of shares
      of
      Common Stock issuable upon the exercise of such Options or upon the conversion
      or exchange of all such Convertible Securities issuable upon the exercise of
      such Options) shall be less than the Warrant Price in effect immediately prior
      to the time of the granting of such Options, then the total number of shares
      of
      Common Stock issuable upon the exercise of such Options or upon conversion
      or
      exchange of the total amount of such Convertible Securities issuable upon the
      exercise of such Options shall be deemed to have been issued for such price
      per
      share as of the date of granting of such Options or the issuance of such
      Convertible Securities and thereafter shall be deemed to be outstanding for
      purposes of adjusting the Warrant Price. Except as otherwise provided in
      subsection 8(f)(3), no adjustment of the Warrant Price shall be made upon the
      actual issue of such Common Stock or of such Convertible Securities upon
      exercise of such Options or upon the actual issue of such Common Stock upon
      conversion or exchange of such Convertible Securities.

    
      
        
        

      

      
        -7-

        
          

        

      

      
        
        

      

    

    

    (f)(2)
      Issuance of Convertible Securities. In case the Company shall in any manner
      issue (directly and not by assumption in a merger or otherwise) or sell any
      Convertible Securities, whether or not the rights to exchange or convert any
      such Convertible Securities are immediately exercisable, and the price per
      share
      for which Common Stock is issuable upon such conversion or exchange (determined
      by dividing (i) the sum (which sum shall constitute the applicable
      consideration) of (x) the total amount received or receivable by the Company
      as
      consideration for the issue or sale of such Convertible Securities, plus (y)
      the
      aggregate amount of additional consideration, if any, payable to the Company
      upon the conversion or exchange thereof, by (ii) the total number of shares
      of
      Common Stock issuable upon the conversion or exchange of all such Convertible
      Securities) shall be less than the Warrant Price in effect immediately prior
      to
      the time of such issue or sale, then the total maximum number of shares of
      Common Stock issuable upon conversion or exchange of all such Convertible
      Securities shall be deemed to have been issued for such price per share as
      of
      the date of the issue or sale of such Convertible Securities and thereafter
      shall be deemed to be outstanding for purposes of adjusting the Warrant Price,
      provided that (a) except as otherwise provided in subsection 8(f)(3), no
      adjustment of the Warrant Price shall be made upon the actual issuance of such
      Common Stock upon conversion or exchange of such Convertible Securities and
      (b)
      no further adjustment of the Warrant Price shall be made by reason of the issue
      or sale of Convertible Securities upon exercise of any Options to purchase
      any
      such Convertible Securities for which adjustments of the Warrant Price have
      been
      made pursuant to the other provisions of subsection 8(f).

     

    (f)(3)
      Change in Option Price or Conversion Rate. Upon the happening of any of the
      following events, namely, if the purchase price provided for in any Option
      referred to in subsection 8(f)(l) hereof, the additional consideration, if
      any,
      payable upon the conversion or exchange of any Convertible Securities referred
      to in subsections 8(f)(l) or 8(f)(2), or the rate at which Convertible
      Securities referred to in subsections 8(f)(l) or 8(f)(2) are convertible into
      or
      exchangeable for Common Stock shall change at any time (including, but not
      limited to, changes under or by reason of provisions designed to protect against
      dilution), the Warrant Price in effect at the time of such event shall forthwith
      be readjusted to the Warrant Price which would have been in effect at such
      time
      had such Options or Convertible Securities still outstanding provided for such
      changed purchase price, additional consideration or conversion rate, as the
      case
      may be, at the time initially granted, issued or sold. On the termination of
      any
      Option for which any adjustment was made pursuant to this subsection 8(f) or
      any
      right to convert or exchange Convertible Securities for which any adjustment
      was
      made pursuant to this subsection 8(f) (including without limitation upon the
      redemption or purchase for consideration of such Convertible Securities by
      the
      Company), the Warrant Price then in effect hereunder shall forthwith be changed
      to the Warrant Price which would have been in effect at the time of such
      termination had such Option or Convertible Securities, to the extent outstanding
      immediately prior to such termination, never been issued.

     

    
      
        
        

      

      
        -8-

        
          

        

      

      
        
        

      

    

     

    (f)(4)
      Stock Dividends. Subject to the provisions of this Section 8(f), in case the
      Company shall declare or pay a dividend or make any other distribution upon
      any
      stock of the Company (other than the Common Stock) payable in Common Stock,
      Options or Convertible Securities, then any Common Stock, Options or Convertible
      Securities, as the case may be, issuable in payment of such dividend or
      distribution shall be deemed to have been issued or sold without
      consideration.

    

    (f)(5)
      Consideration for Stock. In case any shares of Common Stock, Options or
      Convertible Securities shall be issued or sold for cash, the consideration
      received therefor shall be deemed to be the net amount received by the Company
      therefor, after deduction therefrom of any expenses incurred or any underwriting
      commissions or concessions paid or allowed by the Company in connection
      therewith. In case any shares of Common Stock, Options or Convertible Securities
      shall be issued or sold for a consideration other than cash, the amount of
      the
      consideration other than cash received by the Company shall be deemed to be
      the
      fair value of such consideration as determined in good faith by the Board of
      Directors of the Company, after deduction of any expenses incurred or any
      underwriting commissions or concessions paid or allowed by the Company in
      connection therewith. In case any Options shall be issued in connection with
      the
      issue and sale of other securities of the Company, together comprising one
      integral transaction in which no specific consideration is allocated to such
      Options by the parties thereto, such Options shall be deemed to have been issued
      for such consideration as determined in good faith by the Board of Directors
      of
      the Company. If Common Stock, Options or Convertible Securities shall be issued
      or sold by the Company and, in connection therewith, other Options or
      Convertible Securities (the “Additional Rights”) are issued, then the
      consideration received or deemed to be received by the Company shall be reduced
      by the fair market value of the Additional Rights (as determined using the
      Black-Scholes option pricing model or another method mutually agreed to by
      the
      Company and the Warrantholder). The Board of Directors of the Company shall
      respond promptly, in writing, to an inquiry by the Warrantholder as to the
      fair
      market value of the Additional Rights. In the event that the Board of Directors
      of the Company and the Warrantholder are unable to agree upon the fair market
      value of the Additional Rights, the Company and the Warrantholder shall jointly
      select an appraiser, who is experienced in such matters. The decision of such
      appraiser shall be final and conclusive, and the cost of such appraiser shall
      be
      borne evenly by the Company and the Warrantholder.

    

    (f)(6)
      Record Date. In case the Company shall take a record of the holders of its
      Common Stock for the purpose of entitling them (i) to receive a dividend or
      other distribution payable in Common Stock, Options or Convertible Securities
      or
      (ii) to subscribe for or purchase Common Stock, Options or Convertible
      Securities, then such record date shall be deemed to be the date of the issue
      or
      sale of the shares of Common Stock deemed to have been issued or sold upon
      the
      declaration of such dividend or the making of such other distribution or the
      date of the granting of such right of subscription or purchase, as the case
      may
      be.

    
      
        
        

      

      
        -9-

        
          

        

      

      
        
        

      

    

     

    (f)(7)
      Treasury Shares. The number of shares of Common Stock outstanding at any given
      time shall not include shares owned or held by or for the account of the Company
      or any of its wholly-owned subsidiaries, and the disposition of any such shares
      (other than the cancellation or retirement thereof) shall be considered an
      issue
      or sale of Common Stock for the purpose of this subsection (f).

    

    (g) Anything
      herein to the contrary notwithstanding, the Company shall not be required to
      make any adjustment of the Warrant Price in the case of the issuance of
(A)
      capital stock, Options or Convertible Securities issued to directors, officers,
      employees or consultants of the Company in connection with their service as
      directors of the Company, their employment by the Company or their retention
      as
      consultants by the Company pursuant to an equity compensation program approved
      by the Board of Directors of the Company or the compensation committee of the
      Board of Directors of the Company, (B) shares of Common Stock issued upon the
      conversion or exercise of Options or Convertible Securities issued prior to
      the
      date hereof, provided such securities are not amended after the date hereof
      to
      increase the number of shares of Common Stock issuable thereunder or to lower
      the exercise or conversion price thereof, (C) securities issued pursuant to
      the
      Purchase Agreement and securities issued upon the exercise or conversion of
      those securities, and (D) shares of Common Stock issued or issuable by reason
      of
      a dividend, stock split or other distribution on shares of Common Stock (but
      only to the extent that such a dividend, split or distribution results in an
      adjustment in the Warrant Price pursuant to the other provisions of this
      Warrant) (collectively, “Excluded Issuances”).

    

    (h) Upon
      any
      adjustment to the Warrant Price pursuant to Section 8(f) above, the number
      of
      Warrant Shares purchasable hereunder shall be adjusted by multiplying such
      number by a fraction, the numerator of which shall be the Warrant Price in
      effect immediately prior to such adjustment and the denominator of which shall
      be the Warrant Price in effect immediately thereafter.

    

    (i) To
      the
      extent permitted by applicable law and the listing requirements of any stock
      market or exchange on which the Common Stock is then listed, the Company from
      time to time may decrease the Warrant Price by any amount for any period of
      time
      if the period is at least twenty (20) days, the decrease is irrevocable during
      the period and the Board shall have made a determination that such decrease
      would be in the best interests of the Company, which determination shall be
      conclusive. Whenever the Warrant Price is decreased pursuant to the preceding
      sentence, the Company shall provide written notice thereof to the Warrantholder
      at least five (5) days prior to the date the decreased Warrant Price takes
      effect, and such notice shall state the decreased Warrant Price and the period
      during which it will be in effect.

    

    Section
      9. Fractional
      Interest.
      The
      Company shall not be required to issue fractions of Warrant Shares upon the
      exercise of this Warrant. If any fractional share of Common Stock would, except
      for the provisions of the first sentence of this Section 9, be deliverable
      upon
      such exercise, the Company, in lieu of delivering such fractional share, shall
      pay to the exercising Warrantholder an amount in cash equal to the Market Price
      of such fractional share of Common Stock on the date of
      exercise.

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

    

    Section
      10. Extension
      of Expiration Date.
      Except
      as excused pursuant to Section 2(d) of the Registration Rights Agreement
      relating to the Warrant Shares (the “Registration Rights Agreement”), if the
      Company fails to cause any Registration Statement covering Registrable
      Securities (as defined in the Registration Rights Agreement) to be declared
      effective prior to the applicable dates set forth therein, or if any of the
      events specified in Section 2(c)(ii) of the Registration Rights Agreement
      occurs, and the Blackout Period (as defined in the Registration Rights
      Agreement) (whether alone, or in combination with any other Blackout Period)
      continues for more than 60 days in any 12 month period, or for more than a
      total
      of 90 days, then the Expiration Date of this Warrant shall be extended one
      day
      for each day beyond the 60-day or 90-day limits, as the case may be, that the
      Blackout Period continues.

    

    Section
      11. Benefits.
      Nothing
      in this Warrant shall be construed to give any person, firm or corporation
      (other than the Company and the Warrantholder) any legal or equitable right,
      remedy or claim, it being agreed that this Warrant shall be for the sole and
      exclusive benefit of the Company and the Warrantholder.

    

    Section
      12. Notices
      to Warrantholder.
      Upon
      the happening of any event requiring an adjustment of the Warrant Price, the
      Company shall promptly give written notice thereof to the Warrantholder at
      the
      address appearing in the records of the Company, stating the adjusted Warrant
      Price and the adjusted number of Warrant Shares resulting from such event and
      setting forth in reasonable detail the method of calculation and the facts
      upon
      which such calculation is based. Failure to give such notice to the
      Warrantholder or any defect therein shall not affect the legality or validity
      of
      the subject adjustment.

    

    Section
      13. Identity
      of Transfer Agent.
      The
      Transfer Agent for the Common Stock is Computershare Investor Services. Upon
      the
      appointment of any subsequent transfer agent for the Common Stock or other
      shares of the Company’s capital stock issuable upon the exercise of the rights
      of purchase represented by the Warrant, the Company will mail to the
      Warrantholder a statement setting forth the name and address of such transfer
      agent.

    

    Section
      14. Notices.
      Unless
      otherwise provided, any notice required or permitted under this Warrant shall
      be
      given in writing and shall be deemed effectively given as hereinafter described
      (i) if given by personal delivery, then such notice shall be deemed given upon
      such delivery, (ii) if given by telex or facsimile, then such notice shall
      be
      deemed given upon receipt of confirmation of complete transmittal, (iii) if
      given by mail, then such notice shall be deemed given upon the earlier of (A)
      receipt of such notice by the recipient or (B) three days after such notice
      is
      deposited in first class mail, postage prepaid, and (iv) if given by an
      internationally recognized overnight air courier, then such notice shall be
      deemed given one business day after delivery to such carrier. All notices shall
      be addressed as follows: if to the Warrantholder, at its address as set forth
      in
      the Company’s books and records and, if to the Company, at the address as
      follows, or at such other address as the Warrantholder or the Company may
      designate by ten days’ advance written notice to the other:

    Section
      15. Registration
      Rights.
      The
      initial Warrantholder is entitled to the benefit of certain registration rights
      with respect to the shares of Common Stock issuable upon the exercise of this
      Warrant as provided in the Registration Rights Agreement, and any subsequent
      Warrantholder may be entitled to such rights.

    

    Section
      16. 
      Successors.
      All the
      covenants and provisions hereof by or for the benefit of the Warrantholder
      shall
      bind and inure to the benefit of its respective successors and assigns
      hereunder. 

    

    Section
      17. Governing
      Law; Consent to Jurisdiction; Waiver of Jury Trial.
      This
      Warrant shall be governed by, and construed in accordance with, the internal
      laws of the State of New York, without reference to the choice of law provisions
      thereof (other than Section 5-1401 of the New York General Obligation Law).
      The
      Company and, by accepting this Warrant, the Warrantholder, each irrevocably
      submits to the exclusive jurisdiction of the courts of the State of New York
      located in New York County and the United States District Court for the Southern
      District of New York for the purpose of any suit, action, proceeding or judgment
      relating to or arising out of this Warrant and the transactions contemplated
      hereby. Service of process in connection with any such suit, action or
      proceeding may be served on each party hereto anywhere in the world by the
      same
      methods as are specified for the giving of notices under this Warrant. The
      Company and, by accepting this Warrant, the Warrantholder, each irrevocably
      consents to the jurisdiction of any such court in any such suit, action or
      proceeding and to the laying of venue in such court. The Company and, by
      accepting this Warrant, the Warrantholder, each irrevocably waives any objection
      to the laying of venue of any such suit, action or proceeding brought in such
      courts and irrevocably waives any claim that any such suit, action or proceeding
      brought in any such court has been brought in an inconvenient forum.
EACH
      OF THE COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE WARRANTHOLDER HEREBY WAIVES
      ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS
      WARRANT AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS
      WAIVER.

    Section
      18. Call
      Provision.
      Notwithstanding any other provision contained in this Warrant to the contrary,
      from and after the second anniversary of the Closing Date (as defined in the
      Purchase Agreement) in the event that the closing bid price per share of Common
      Stock as traded on the Bulletin Board (or such other exchange or stock market
      on
      which the Common Stock may then be listed or quoted) equals or exceeds $0.50
      (appropriately adjusted for any stock split, reverse stock split, stock dividend
      or other reclassification or combination of the Common Stock occurring after
      the
      date hereof) for twenty (20) consecutive trading days commencing after the
      Registration Statement (as defined in the Registration Rights Agreement) has
      been declared effective, the Company, upon thirty (30) days prior written notice
      (the “Notice
      Period”)
      given
      to the Warrantholder within one business day immediately following the end
      of
      such twenty (20) trading day period, may call this Warrant, in whole but not
      in
      part, at a redemption price equal to $0.01 per share of Common Stock then
      purchasable pursuant to this Warrant; provided that (i) the Company
      simultaneously calls all Company Warrants (as defined below) on the same terms,
      (ii) all of the shares of Common Stock issuable hereunder either (A) are
      registered pursuant to an effective Registration Statement (as defined in the
      Registration Rights Agreement) which is not suspended and for which no stop
      order is in effect, and pursuant to which the Warrantholder is able to sell
      such

      of
      the aggregate Warrant Price in respect of the shares of Common Stock to be
      acquired, shares of Common Stock of equal value to the value of this Warrant,

      (including both shares to be issued to the Warrantholder and shares as to which
      the purchase rights are to be canceled as payment therefor);

    A
      = the
      “Market Price” of one share of Common Stock as at the date the net issue
      election is made; and

    

    B
      = the
      Warrant Price in effect under this Warrant at the time the net issue election
      is
      made.

    

    Section
      20. No
      Rights as Stockholder.
      Prior

      Waiver.

      RECEIVED, Precision Optics Corporation, Inc., a Massachusetts corporation (the

      hereby unconditionally promises to pay to the order of ________________ (the
      “Holder”),
      having an address at [527 Madison Avenue, 26th
      Floor,
      New York, NY 10022][address of other Holders], at such address or at such other
      place as may be designated in writing by the Holder, or its assigns, the
      aggregate principal sum of _____________ United States Dollars
      ($______________), together with interest from the date set forth above on
      the
      unpaid principal balance of this Note outstanding at a rate equal to ten percent
      (10.0%) (computed on the basis of the actual number of days elapsed in a 360-day
      year) per annum and continuing on the outstanding principal until this 10%
      Senior Secured Convertible Note (the “Note”)
      is
      converted into Common Stock as provided herein or indefeasibly and irrevocably
      paid in full by the Company. Subject to the other provisions of this Note,
      the
      principal of this Note and all accrued and unpaid interest hereon shall mature
      and become due and payable on June 25, 2010 (the “Stated
      Maturity Date”).
      Except as provided herein, all payments of principal and interest by the Company
      under this Note shall be made in United States dollars in immediately available
      funds to an account specified by the Holder. At the option of the Holder,

      date of payment equal to the interest due hereon.

     

    In
      the
      event that any amount due hereunder is not paid when due, such overdue amount
      shall bear interest at an annual rate of fifteen percent (15%) until paid in
      full. In no event shall any interest charged, collected or reserved under this
      Note exceed the maximum rate then permitted by applicable law and if any such
      payment is paid by the Company, then such excess sum shall be credited by the
      Holder as a payment of principal.

     

    This
      Note
      is one of a series of Notes (the “Company
      Notes”)

    3. No

    (a) This
      Note
      shall not be prepayable or redeemable by the Company prior to the Stated
      Maturity Date.

     

    (b) In
      the
      event that a Change of Control occurs prior to the Amendment Effective Date,
      the
      Company shall redeem as of the effective time of the Change of Control (the
      “Redemption
      Date”)
      all,
      but not less than all, of the principal amount of this Note and all accrued
      interest thereon at a cash redemption price equal to the product of (i) the
      number of shares of Common Stock into which this Note and all accrued and unpaid
      interest thereon would have been convertible if the Note was convertible on
      the
      Redemption Date and (ii) the Fair Market Value of the consideration per share
      to
      be received by holders of Common Stock in connection with such Change of Control
      as of the Redemption Date (the “Redemption
      Price”).

      Market Value”,
      (i)
      publicly traded securities shall be deemed to have a Fair Market Value equal
      to
      their Market Price, and (ii) any other securities or other assets shall be
      deemed to have a Fair Market Value equal to the fair market value thereof as
      determined by the Board in the good faith exercise of its reasonable business
      judgment. The Company shall provide written notice to the Holder of this Note
      of
      any pending Change of Control not less than 15 days prior to the effective
      date
      of such Change of Control, which notice shall include the Company’s estimate of
      the Redemption Price. On the Redemption Date, the Company shall pay the
      Redemption Price to the Holder in immediately available funds to an account
      previously specified in writing by the Holder. The Holder shall not be required
      to surrender this Note prior to payment of the Redemption Price. Upon the
      indefeasible payment in full of the Redemption Price to the Holder as provided
      in this Section 3, this Note shall be deemed to have been paid in full and
      shall
      no longer be outstanding for any purpose.

    4. Conversion
      Rights.

     

    (a) Prior
      to
      the Amendment Effective Date, this Note shall not be convertible. From and
      after
      the Amendment Effective Date, prior to the Stated Maturity Date and subject
      to
      and upon compliance with the provisions of this Note, the Holder shall have
      the
      right, at its option at any time, to convert some or all of the Note into such
      number of fully paid and nonassessable shares of Common Stock as is obtained
      by:
      (i) adding (A) the principal amount of this Note to be converted and (B) the
      amount of any accrued but unpaid interest with respect to such portion of this
      Note to be converted; and (ii) dividing the result obtained pursuant to clause
      (i) above by the Conversion Price then in effect. The rights of conversion
      set
      forth in this Section 4 shall be exercised by the Holder by giving written
      notice to the Company that the Holder elects to convert a stated amount of
      this
      Note into Common Stock and by surrender of this Note (or, in lieu thereof,
      by
      delivery of an appropriate lost security affidavit in the event this Note shall
      have been lost or destroyed) to the Company at its principal office (or such
      other office or agency of the Company as the Company may designate by notice
      in
      writing to the Holder) at any time on the date set forth in such notice (which
      date shall not be earlier than the Company’s receipt of such notice), together
      with a statement of the name or names (with address) in which the certificate
      or
      certificates for shares of Common Stock shall be issued.

     

    (b) Promptly
      after receipt of the written notice referred to in Section 4(a) above and
      surrender of this Note (or, in lieu thereof, by delivery of an appropriate
      lost
      security affidavit in the event this Note shall have been lost or destroyed),
      but in no event more than three (3) Business Days thereafter, the Company shall
      issue and deliver, or cause to be issued and delivered, to the Holder,
      registered in such name or names as the Holder may direct in writing, a
      certificate or certificates for the number of whole shares of Common Stock
      issuable upon the conversion of such portion of this Note. To the extent
      permitted by law, such conversion shall be deemed to have been effected, and
      the
      Conversion Price shall be determined, as of the close of business on the date
      on
      which such written notice shall have been received by the Company and this
      Note
      shall have been surrendered as aforesaid (or, in lieu thereof, an appropriate
      lost security affidavit has been delivered to the Company), and at such time,
      the rights of the Holder shall cease with respect to the principal amount of
      the
      Notes being converted, and the Person or Persons in whose name or names any
      certificate or certificates for shares of Common Stock shall be issuable upon
      such conversion shall be deemed to have become the holder or holders of record
      of the shares represented thereby.

     

    (c) No
      fractional shares shall be issued upon any conversion of this Note into Common
      Stock. If any fractional share of Common Stock would, except for the provisions
      of the first sentence of this Section 4(c), be delivered upon such conversion,
      the Company, in lieu of delivering such fractional share, shall pay to the
      Holder an amount in cash equal to the Market Price of such fractional share
      of
      Common Stock. In case the principal amount of this Note exceeds the principal
      amount being converted, the Company shall, upon such conversion, execute and
      deliver to the Holder, at the expense of the Company, a new Note for the
      principal amount of this Note surrendered which is not to be
      converted.

    
       

      
        
          
          

        

        
          -7-

          
            

          

        

        
          
          

        

      

       

    

    (d) If
      the
      Company shall, at any time or from time to time while this Note is outstanding,
      pay a dividend or make a distribution on its Common Stock in shares of Common
      Stock, subdivide its outstanding shares of Common Stock into a greater number
      of
      shares or combine its outstanding shares of Common Stock into a smaller number
      of shares or issue by reclassification of its outstanding shares of Common
      Stock
      any shares of its capital stock (including any such reclassification in
      connection with a consolidation or merger in which the Company is the continuing
      corporation), then the Conversion Price in effect immediately prior to the
      date
      upon which such change shall become effective, shall be adjusted by the Company
      so that the Holder thereafter converting this Note shall be entitled to receive
      the number of shares of Common Stock or other capital stock which the Holder
      would have received if the Note had been converted immediately prior to such
      event upon payment of a Conversion Price that has been adjusted to reflect
      a
      fair allocation of the economics of such event to the Holder, without regard
      to
      any conversion limitation specified in this Section 4. Such adjustments shall
      be
      made successively whenever any event listed above shall occur.

     

    (e) If
      any
      capital reorganization, reclassification of the capital stock of the Company,
      consolidation or merger of the Company with another corporation in which the
      Company is not the survivor, or sale, transfer or other disposition of all
      or
      substantially all of the Company’s assets to another corporation shall be
      effected, then, as a condition of such reorganization, reclassification,
      consolidation, merger, sale, transfer or other disposition, lawful and adequate
      provision shall be made whereby the Holder shall thereafter have the right
      to
      purchase and receive upon the basis and upon the terms and conditions herein
      specified and in lieu of the shares of Common Stock immediately theretofore
      issuable upon conversion of this Note such shares of stock, securities or assets
      as would have been issuable or payable with respect to or in exchange for a
      number of shares of Common Stock equal to the number of shares of Common Stock
      immediately theretofore issuable upon conversion of this Note, had such
      reorganization, reclassification, consolidation, merger, sale, transfer or
      other
      disposition not taken place, and in any such case appropriate provision shall
      be
      made with respect to the rights and interests of the Holder to the end that
      the
      provisions hereof (including, without limitation, provision for adjustment
      of
      the Conversion Price) shall thereafter be applicable, as nearly equivalent
      as
      may be practicable in relation to any shares of stock, securities or assets
      thereafter deliverable upon the conversion hereof. The Company shall not effect
      any such consolidation, merger, sale, transfer or other disposition unless
      prior
      to or simultaneously with the consummation thereof the successor corporation
      (if
      other than the Company) resulting from such consolidation or merger, or the
      corporation purchasing or otherwise acquiring such assets or other appropriate
      corporation or entity shall assume the obligation to deliver to the Holder,
      at
      the last address of the Holder appearing on the books of the Company, such
      shares of stock, securities or assets as, in accordance with the foregoing
      provisions, the Holder may be entitled to purchase, without regard to any
      conversion limitation specified in Section 4, and the other obligations under
      this Note. The provisions of this paragraph (e) shall similarly apply to
      successive reorganizations, reclassifications, consolidations, mergers, sales,
      transfers or other dispositions.

    
       

      
        
          
          

        

        
          -8-

          
            

          

        

        
          
          

        

      

       

    

    (f) In
      case
      the Company shall fix a payment date for the making of a distribution to all
      holders of Common Stock (including any such distribution made in connection
      with
      a consolidation or merger in which the Company is the continuing corporation)
      of
      evidences of indebtedness or assets (other than cash dividends or cash
      distributions payable out of consolidated earnings or earned surplus or
      dividends or distributions referred to in Section 4(d)), or subscription rights
      or Notes, the Conversion Price to be in effect after such payment date shall
      be
      determined by multiplying the Conversion Price in effect immediately prior
      to
      such payment date by a fraction, the numerator of which shall be the total
      number of shares of Common Stock outstanding multiplied by the Market Price
      of
      Common Stock immediately prior to such payment date, less the fair market value
      (as determined by the Board in good faith) of said assets or evidences of
      indebtedness so distributed, or of such subscription rights or Notes, and the
      denominator of which shall be the total number of shares of Common Stock
      outstanding multiplied by such Market Price immediately prior to such payment
      date. Such adjustment shall be made successively whenever such a payment date
      is
      fixed.

     

    (g) An
      adjustment to the Conversion Price shall become effective immediately after
      the
      payment date in the case of each dividend or distribution and immediately after
      the effective date of each other event which requires an
      adjustment.

     

    (h) In
      the
      event that, as a result of an adjustment made pursuant to this Section 4, the
      Holder shall become entitled to receive any shares of capital stock of the
      Company other than shares of Common Stock, the number of such other shares
      so
      receivable upon conversion of this Note shall be subject thereafter to
      adjustment from time to time in a manner and on terms as nearly equivalent
      as
      practicable to the provisions contained in this Note.

     

    (i) Except
      as
      provided in Section 4(j) hereof, if and whenever the Company shall issue or
      sell, or is, in accordance with any of Sections 4(i)(i) through 4(i)(vii)
      hereof, deemed to have issued or sold, any shares of Common Stock for no
      consideration or for a consideration per share less than the Conversion Price
      in
      effect immediately prior to the time of such issue or sale, then and in each
      such case (a “Trigger
      Issuance”)
      the
      then-existing Conversion Price, shall be reduced, as of the close of business
      on
      the effective date of the Trigger Issuance, to a price determined as
      follows:

     

    
      
        	
                Adjusted Conversion Price = 
                  

              	
                (A
                  x B) + D

              
	
                 

              	
                A+C

              

      

    

     

    where

    

    “A”
      equals the number of shares of Common Stock outstanding, including Additional
      Shares of Common Stock (as defined below) deemed to be issued hereunder,
      immediately preceding such Trigger Issuance (but excluding the Additional Shares
      included in “C” below);

    

    “B”
      equals the Conversion Price in effect immediately preceding such Trigger
      Issuance;

     

    
      
        
        

      

      
        -9-

        
          

        

      

      
        
        

      

    

    

    “C”
      equals the number of Additional Shares of Common Stock issued or deemed issued
      hereunder as a result of the Trigger Issuance; and

    

    “D”
      equals the aggregate consideration, if any, received or deemed to be received
      by
      the Company upon such Trigger Issuance;

    

    provided,
      however, that in no event shall the Conversion Price after giving effect to
      such
      Trigger Issuance be greater than the Conversion Price in effect prior to such
      Trigger Issuance.

    

    For
      purposes of this subsection (i), “Additional Shares of Common Stock” shall mean
      all shares of Common Stock issued by the Company or deemed to be issued pursuant
      to this subsection (i), other than Excluded Issuances (as defined in subsection
      (j) hereof).

     

    For
      purposes of this Section 4(i), the following subsections (i)(i) to (i)(vii)
      shall also be applicable (subject, in each such case, to the provisions of
      Section 4(j) hereof):

    

    (i) In
      case
      at any time the Company shall in any manner grant (directly and not by
      assumption in a merger or otherwise) any Notes or other rights to subscribe
      for
      or to purchase, or any options for the purchase of, Common Stock or any stock
      or
      security convertible into or exchangeable for Common Stock (such Notes, rights
      or options being called “Options”
and
      such convertible or exchangeable stock or securities being called “Convertible
      Securities”)
      whether or not such Options or the right to convert or exchange any such
      Convertible Securities are immediately exercisable, and the price per share
      for
      which Common Stock is issuable upon the exercise of such Options or upon the
      conversion or exchange of such Convertible Securities (determined by dividing
      (i) the sum (which sum shall constitute the applicable consideration) of (x)
      the
      total amount, if any, received or receivable by the Company as consideration
      for
      the granting of such Options, plus (y) the aggregate amount of additional
      consideration payable to the Company upon the exercise of all such Options,
      plus
      (z), in the case of such Options which relate to Convertible Securities, the
      aggregate amount of additional consideration, if any, payable upon the issue
      or
      sale of such Convertible Securities and upon the conversion or exchange thereof,
      by (ii) the total maximum number of shares of Common Stock issuable upon the
      exercise of such Options or upon the conversion or exchange of all such
      Convertible Securities issuable upon the exercise of such Options) shall be
      less
      than the Market Price of the Common Stock immediately prior to the time of
      the
      granting of such Options, then the total number of shares of Common Stock
      issuable upon the exercise of such Options or upon conversion or exchange of
      the
      total amount of such Convertible Securities issuable upon the exercise of such
      Options shall be deemed to have been issued for such price per share as of
      the
      date of granting of such Options or the issuance of such Convertible Securities
      and thereafter shall be deemed to be outstanding for purposes of adjusting
      the
      Conversion Price. Except as otherwise provided in subsection 4(i)(iii), no
      adjustment of the Conversion Price shall be made upon the actual issue of such
      Common Stock or of such Convertible Securities upon exercise of such Options
      or
      upon the actual issue of such Common Stock upon conversion or exchange of such
      Convertible Securities.

     

    (ii) In
      case
      the Company shall in any manner issue (directly and not by assumption in a
      merger or otherwise) or sell any Convertible Securities, whether or not the
      rights to exchange or convert any such Convertible Securities are immediately
      exercisable, and the price per share for which Common Stock is issuable upon
      such conversion or exchange (determined by dividing (i) the sum (which sum
      shall
      constitute the applicable consideration) of (x) the total amount received or
      receivable by the Company as consideration for the issue or sale of such
      Convertible Securities, plus (y) the aggregate amount of additional
      consideration, if any, payable to the Company upon the conversion or exchange
      thereof, by (ii) the total number of shares of Common Stock issuable upon the
      conversion or exchange of all such Convertible Securities) shall be less than
      the Market Price of the Common Stock immediately prior to the time of such
      issue
      or sale, then the total maximum number of shares of Common Stock issuable upon
      conversion or exchange of all such Convertible Securities shall be deemed to
      have been issued for such price per share as of the date of the issue or sale
      of
      such Convertible Securities and thereafter shall be deemed to be outstanding
      for
      purposes of adjusting the Conversion Price, provided that (a) except as
      otherwise provided in subsection 4(i)(iii), no adjustment of the Conversion
      Price shall be made upon the actual issuance of such Common Stock upon
      conversion or exchange of such Convertible Securities and (b) no further
      adjustment of the Conversion Price shall be made by reason of the issue or
      sale
      of Convertible Securities upon exercise of any Options to purchase any such
      Convertible Securities for which adjustments of the Conversion Price have been
      made pursuant to the other provisions of subsection 6(i).

     

    
      
        
        

      

      
        -10-

        
          

        

      

      
        
        

      

    

     

    (iii) Upon
      the
      happening of any of the following events, namely, if the purchase price provided
      for in any Option referred to in subsection 4(i)(i) hereof, the additional
      consideration, if any, payable upon the conversion or exchange of any
      Convertible Securities referred to in subsections 4(i)(i) or 4(i)(ii), or the
      rate at which Convertible Securities referred to in subsections 4(i)(i) or
      4(i)(ii) are convertible into or exchangeable for Common Stock shall change
      at
      any time (including, but not limited to, changes under or by reason of
      provisions designed to protect against dilution), the Conversion Price in effect
      at the time of such event shall forthwith be readjusted to the Conversion Price
      which would have been in effect at such time had such Options or Convertible
      Securities still outstanding provided for such changed purchase price,
      additional consideration or conversion rate, as the case may be, at the time
      initially granted, issued or sold. On the termination of any Option for which
      any adjustment was made pursuant to this subsection 4(i) or any right to convert
      or exchange Convertible Securities for which any adjustment was made pursuant
      to
      this subsection 4(i) (including without limitation upon the redemption or
      purchase for consideration of such Convertible Securities by the Company),
      the
      Conversion Price then in effect hereunder shall forthwith be changed to the
      Conversion Price which would have been in effect at the time of such termination
      had such Option or Convertible Securities, to the extent outstanding immediately
      prior to such termination, never been issued.

     

    (iv) Subject
      to the provisions of this Section 4(i), in case the Company shall declare a
      dividend or make any other distribution upon any stock of the Company (other
      than the Common Stock) payable in Common Stock, Options or Convertible
      Securities, then any Common Stock, Options or Convertible Securities, as the
      case may be, issuable in payment of such dividend or distribution shall be
      deemed to have been issued or sold without consideration.

     

    (v) In
      case
      any shares of Common Stock, Options or Convertible Securities shall be issued
      or
      sold for cash, the consideration received therefor shall be deemed to be the
      net
      amount received by the Company therefor, after deduction therefrom of any
      expenses incurred or any underwriting commissions or concessions paid or allowed
      by the Company in connection therewith. In case any shares of Common Stock,
      Options or Convertible Securities shall be issued or sold for a consideration
      other than cash, the amount of the consideration other than cash received by
      the
      Company shall be deemed to be the fair value of such consideration as determined
      in good faith by the Board, after deduction of any expenses incurred or any
      underwriting commissions or concessions paid or allowed by the Company in
      connection therewith. In case any Options shall be issued in connection with
      the
      issue and sale of other securities of the Company, together comprising one
      integral transaction in which no specific consideration is allocated to such
      Options by the parties thereto, such Options shall be deemed to have been issued
      for such consideration as determined in good faith by the Board of Directors
      of
      the Company. If Common Stock, Options or Convertible Securities shall be issued
      or sold by the Company and, in connection therewith, other Options or
      Convertible Securities (the “Additional
      Rights”)
      are
      issued, then the consideration received or deemed to be received by the Company
      shall be reduced by the fair market value of the Additional Rights (as
      determined using the Black-Scholes option pricing model or another method
      mutually agreed to by the Company and the Holder). The Board shall respond
      promptly, in writing, to an inquiry by the Holder as to the fair market value
      of
      the Additional Rights. In the event that the Board and the Holder are unable
      to
      agree upon the fair market value of the Additional Rights, the Company and
      the
      Holder shall jointly select an appraiser, who is experienced in such matters.
      The decision of such appraiser shall be final and conclusive, and the cost
      of
      such appraiser shall be borne evenly by the Company and the Holder.

     

    
      
        
        

      

      
        -11-

        
          

        

      

      
        
        

      

    

     

    (vi) In
      case
      the Company shall take a record of the holders of its Common Stock for the
      purpose of entitling them (i) to receive a dividend or other distribution
      payable in Common Stock, Options or Convertible Securities or (ii) to subscribe
      for or purchase Common Stock, Options or Convertible Securities, then such
      record date shall be deemed to be the date of the issue or sale of the shares
      of
      Common Stock deemed to have been issued or sold upon the declaration of such
      dividend or the making of such other distribution or the date of the granting
      of
      such right of subscription or purchase, as the case may be.

     

    (vii) The
      number of shares of Common Stock outstanding at any given time shall not include
      shares owned or held by or for the account of the Company or any of its
      wholly-owned subsidiaries, and the disposition of any such shares (other than
      the cancellation or retirement thereof) shall be considered an issue or sale
      of
      Common Stock for the purpose of this subsection (i).

     

    (j) Anything
      herein to the contrary notwithstanding, the Company shall not be required to
      make any adjustment of the Conversion Price in the case of the issuance of
      (A)
      capital stock, Options or Convertible Securities issued to (i) directors,
      officers, employees or consultants of the Company in connection with their
      service as directors of the Company, their employment by the Company or their
      retention as consultants by the Company pursuant to an equity compensation
      program approved by the Board of Directors of the Company or the compensation
      committee of the Board of Directors of the Company or (ii) landlords and/or
      commercial lenders; provided, that in the case of any issuance pursuant to
      this
      clause (A), the exercise or conversion price of any such Options or Convertible
      Securities shall be at least equal to the Market Price on the date of grant,
      (B)
      shares of Common Stock issued upon the conversion or exercise of Options or
      Convertible Securities issued prior to the date hereof, provided such securities
      are not amended after the date hereof, (C) securities issued pursuant to the
      Purchase Agreement and securities issued upon the exercise or conversion of
      those securities, and (D) shares of Common Stock issued or issuable by reason
      of
      a dividend, stock split or other distribution on shares of Common Stock (but
      only to the extent that such a dividend, split or distribution results in an
      adjustment in the Conversion Price pursuant to the other provisions of this
      Note) (collectively, “Excluded
      Issuances”).

     

    
      
        
        

      

      
        -12-

        
          

        

      

      
        
        

      

    

     

    (k) In
      case
      at any time:

     

    (i) the
      Company shall declare any dividend upon its Common Stock or any other class
      or
      series of capital stock of the Company payable in cash or stock or make any
      other distribution to the holders of its Common Stock or any such other class
      or
      series of capital stock;

     

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

     

    (iii) there
      shall be any capital reorganization or reclassification of the capital stock
      of
      the Company, any acquisition or a liquidation, dissolution or winding up of
      the
      Company; 

     

    then,
      in
      any one or more of said cases, the Company shall give, by delivery in person
      or
      by certified or registered mail, return receipt requested, addressed to the
      Holder at the address of such Holder as shown on the books of the Company,
      (a)
      at least 20 Business Days’ prior written notice of the date on which the books
      of the Company shall close or a record shall be taken for such dividend,
      distribution or subscription rights or for determining rights to vote in respect
      of any event set forth in clause (iii) of this Section 4(k) and (b) in the
      case
      of any event set forth in clause (iii) of this Section 4(k), at least 20
      Business Days’ prior written notice of the date when the same shall take place.
      Such notice in accordance with the foregoing clause (a) shall also specify,
      in
      the case of any such dividend, distribution or subscription rights, the date
      on
      which the holders of Common Stock or such other class or series of capital
      stock
      shall be entitled thereto and such notice in accordance with the foregoing
      clause (b) shall also specify the date on which the holders of Common Stock
      and
      such other series or class of capital stock shall be entitled to exchange their
      Common Stock and other stock for securities or other property deliverable upon
      consummation of the applicable event set forth in clause (iii) of this Section
      4(k).

    (l) Upon
      any
      adjustment of the Conversion Price, then and in each such case the Company
      shall
      give prompt written notice thereof, by delivery in person or by certified or
      registered mail, return receipt requested, addressed to the Holder at the
      address of such Holder as shown on the books of the Company, which notice shall
      state the Conversion Price resulting from such adjustment and setting forth
      in
      reasonable detail the method upon which such calculation is based.

     

    (m) From
      and
      after the Amendment Effective Date, the Company shall at all times reserve
      and
      keep available out of its authorized Common Stock, solely for the purpose of
      issuance upon conversion of this Note as herein provided, such number of shares
      of Common Stock as shall then be issuable upon the conversion of this Note.
      The
      Company covenants that all shares of Common Stock which shall be so issued
      shall
      be duly and validly issued and fully paid and nonassessable, and free from
      all
      taxes, liens and charges with respect to the issue thereof, and, without
      limiting the generality of the foregoing, and that the Company will from time
      to
      time take all such action as may be requisite to assure that the par value
      per
      share of the Common Stock is at all times equal to or less than the Conversion
      Price in effect at the time. The Company shall take all such action as may
      be
      necessary to assure that all such shares of Common Stock may be so issued
      without violation of any applicable law or regulation, or of any requirement
      of
      any national securities exchange or trading market upon which the Common Stock
      may be listed. The Company shall not take any action which results in any
      adjustment of the Conversion Price if the total number of shares of Common
      Stock
      issued and issuable after such action upon conversion of this Note would exceed
      the total number of shares of Common Stock then authorized by the Company’s
      Certificate of Incorporation.

    
       

      
        
          
          

        

        
          -13-

          
            

          

        

        
          
          

        

      

       

    

    (n) The
      issuance of certificates for shares of Common Stock upon conversion of this
      Note
      shall be made without charge to the holders thereof for any issuance tax in
      respect thereof, provided that the Company shall not be required to pay any
      tax
      which may be payable in respect of any transfer involved in the issuance and
      delivery of any certificate in a name other than that of the
      Holder.

     

    (o) The
      Company will not at any time close its transfer books against the transfer,
      as
      applicable, of this Note or of any shares of Common Stock issued or issuable
      upon the conversion of this Note in any manner which interferes with the timely
      conversion of this Note, except as may otherwise be required to comply with
      applicable securities laws.

     

    (p) To
      the
      extent permitted by applicable law and the listing requirements of any stock
      exchange or trading market on which the Common Stock is then listed, the Company
      from time to time may decrease the Conversion Price by any amount for any period
      of time if the period is at least twenty (20) days, the decrease is irrevocable
      during the period and the Board shall have made a determination that such
      decrease would be in the best interests of the Company, which determination
      shall be conclusive. Whenever the Conversion Price is decreased pursuant to
      the
      preceding sentence, the Company shall provide written notice thereof to the
      Holder at least fifteen (15) days prior to the date the decreased Conversion
      Price takes effect, and such notice shall state the decreased Conversion Price
      and the period during which it will be in effect.

     

    5. Covenants.

     

    (a) So
      long
      as any amount due under this Note is outstanding and until indefeasible payment
      in full of all amounts payable by the Company hereunder:

     

    (i) The
      Company shall and shall cause each of its Subsidiaries to (A) carry on and
      conduct its business in substantially the same manner and in substantially
      the
      same fields of enterprise as it is presently conducting, (B) do all things
      necessary to remain duly organized, validly existing, and in good standing
      as a
      domestic corporation under the laws of its state of incorporation and (C)
      maintain all requisite authority to conduct its business in those jurisdictions
      in which its business is conducted.

     

    
      
        
        

      

      
        -14-

        
          

        

      

      
        
        

      

    

     

    (ii) The
      Company shall promptly notify the Holder in writing of (A) any change in the
      business or the operations the Company or any Subsidiary which could reasonably
      be expected to have a Material Adverse Effect, and (B) any information which
      indicates that any financial statements which are the subject of any
      representation contained in the Transaction Documents, or which are furnished
      to
      the Holder pursuant to the Transaction Documents, fail, in any material respect,
      to present fairly, as of the date thereof and for the period covered thereby,
      the financial condition and results of operations purported to be presented
      therein, disclosing the nature thereof.

     

    (iii) The
      Company shall promptly notify the Holder of the occurrence of any Event of
      Default or any event which, with the giving of notice, the lapse of time or
      both
      would constitute an Event of Default, which notice shall include a written
      statement as to such occurrence, specifying the nature thereof and the action
      (if any) which is proposed to be taken with respect thereto.

     

    (iv) The
      Company shall promptly notify the Holder of any action, suit or proceeding
      at
      law or in equity or by or before any governmental instrumentality or other
      agency against the Company or any Subsidiary or to which the Company or any
      Subsidiary may be subject which alleges damages in excess of One Hundred
      Thousand United States Dollars ($100,000).

     

    (v) The
      Company shall promptly notify the Holder of any default in the performance,
      observance or fulfillment of any of the obligations, covenants or conditions
      contained in any agreement or instrument to which the Company or any Subsidiary
      is a party which default could reasonably be expected to have a Material Adverse
      Effect.

     

    (vi) The
      Company shall and shall cause each Subisidiary to promptly take any and all
      actions necessary to execute any definitive documentation (which documentation
      shall include customary representations, warranties, covenants, conditions
      and
      agreements, and any UCC financing statements) reasonably requested by the
      Holder, for obtaining the benefits of the Security Agreement, subject to the
      terms and conditions stated therein.

     

    (vii) The
      Company shall deliver to the Holder, within thirty (30) days after the end
      of
      each fiscal quarter, a certificate signed by either the Chief Executive Officer
      or the Chief Financial Officer of the Company (which shall include an updated
      perfection certification) as to such officer’s knowledge, of the Company’s

      (iv) shall not exceed $1,000,000 in the aggregate, and (C) no such payment
      may
      be made if an Event of Default or an event which, with the giving of notice,
      the
      lapse of time or both would constitute an Event of Default has occurred and
      is
      continuing or would result from such payment.

      election of the Holder, with respect to (a) through (d) and (f) through (k),

      be immediately due and payable, pursue any available remedy, whether at law
      or

    7. No
      Waiver.
      No
      delay or omission on the part of the Holder in exercising any right under this
      Note shall operate as a waiver of such right or of any other right of the
      Holder, nor shall any delay, omission or waiver on any one occasion be deemed
      a
      bar to or waiver of the same or any other right on any future
      occasion.

     

    8. Amendments
      in Writing.
      Any
      term of this Note may be amended or waived upon the written consent of the
      Company and the holders of Company Notes representing at least 50% of the
      principal amount of Company Notes then outstanding (the “Majority
      Holders”);
      provided,
      that
      (x) any such amendment or waiver must apply to all outstanding Company Notes;
      and (y) without the consent of the Holder hereof, no amendment or waiver shall
      (i) change the Stated Maturity Date of this Note, (ii) reduce the principal
      amount of this Note or the interest rate due hereon, (iii) change the Conversion
      Price or (iv) change the place of payment of this Note. No such waiver or

      of Jury Trial.

      COMPANY HEREBY WAIVES ITS RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
      ARISING OUT OF OR BASED UPON THIS NOTE OR ANY CONTEMPLATED TRANSACTION,

      REVIEWED THIS WAIVER WITH ITS COUNSEL.

      Obligation.

      Note is one of the Notes referred to in the Security Agreement and is secured
      by
      the collateral described therein. The Security Agreement grants the Holder
      certain rights with respect to such collateral upon an Event of
      Default.

     

    12. Governing
      Law; Consent to Jurisdiction.
      This
      Note shall be governed by and construed under the law of the State of New York,

      in
      connection with any such suit, action or proceeding may be served on each party
      hereto anywhere in the world by the same methods as are specified for the giving
      of notices under this Note. The Company and, by accepting this Note, the Holder,
      each irrevocably consents to the jurisdiction of any such court in any such
      suit, action or proceeding and to the laying of venue in such court. The Company
      and, by accepting this Note, the Holder, each irrevocably waives any objection
      to the laying of venue of any such suit, action or proceeding brought in such
      courts and irrevocably waives any claim that any such suit, action or proceeding
      brought in any such court has been brought in an inconvenient
      forum.
