IV. CONVERSION

A.

Optional and Mandatory Conversion

(i)

Optional Conversion.

Holders of shares of Series A Preferred Stock may at their option convert all or any portion of their shares of Series A Preferred Stock into Common Stock of the Corporation at any time or from time to time (an “Optional Conversion”).

Conversion Price then in effect

B.

Mechanics of Conversion. In order to effect an Conversion, a Holder of shares of Series A Preferred Stock shall: (i) fax (or otherwise deliver) a copy of the fully executed Notice of Conversion to the Corporation (Attention: Secretary) and (ii) surrender or cause to be surrendered the original certificates representing the Series A Preferred Stock being converted (the "Series A Preferred Stock Certificates"), duly endorsed, along with a copy of the Notice of Conversion as soon as practicable thereafter to the Corporation.  Upon receipt by the Corporation 

3

of a facsimile copy of a Notice of Conversion from a Holder, the Corporation shall promptly send, via facsimile, a confirmation to such Holder stating that the Notice of Conversion has been received, the date upon which the Corporation expects to deliver the Common Stock issuable upon such conversion and the name and telephone number of a contact person at the Corporation regarding the conversion.  The Corporation shall not be obligated to issue shares of Common Stock upon a conversion unless either the Series A Preferred Stock Certificates are delivered to the Corporation as provided above, or the Holder notifies the Corporation that such Series A Preferred Stock Certificates have been lost, stolen or destroyed and delivers the documentation to the Corporation required by Article XII. B hereof.

(i)

Delivery of Common Stock Upon Conversion. Upon the surrender of Series A Preferred Stock Certificates accompanied by a Notice of Conversion, the Corporation (itself, or through its transfer agent, as appropriate) shall, no later than the later of (a) the tenth Business Day following the Conversion Date and (b) the Business Day following the date of such surrender (or, in the case of lost, stolen or destroyed certificates, after provision of indemnity pursuant to Article XI B) (the "Delivery Period"), issue and deliver (i e., deposit with a nationally recognized overnight courier service portage prepaid) to the Holder or its nominee (x) that number of shares of Common Stock issuable upon conversion of such shares of Series A Preferred Stock being converted and (y) a certificate representing the number of shares of Series A Preferred Stock not being converted, if any.  Notwithstanding the foregoing, if the Corporation's transfer agent is participating in the Depository Trust Corporation ("DTC") Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend (pursuant to the terms of the Securities Purchase Agreement) and the Holder thereof is not then required to return such certificate for the placement of a legend thereon (pursuant to the terms of the Securities Purchase Agreement), the Corporation shall cause its transfer agent to promptly electronically transmit the Common Stock issuable upon conversion to the Holder by crediting the account of the Holder or its nominee with DTC through its Deposit Withdrawal Agent Commission system ("DTC Transfer").  If the aforementioned conditions to a DTC Transfer are not satisfied, the Corporation shall deliver as provided above to the Holder physical certificates representing the Common Stock issuable upon conversion. Further, a Holder may instruct the Corporation to deliver to the Holder physical certificates representing the Common Stock issuable upon conversion in lieu of delivering such shares by way of DTC Transfer.

(ii)

Taxes. The Corporation shall pay any and all taxes that may be imposed upon it respect to the issuance and delivery of the shares of Common Stock upon the conversion of the Series A Preferred Stock.

(iii)

No Fractional Shares.  If any conversion of Series A Preferred Stock would result in the issuance of a fractional share of Common Stock (aggregating all shares of Series A Preferred Stock being converted pursuant to a given Notice of Conversion), such fractional share shall be payable in cash based upon the Conversion Price per share, and the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock shall be the next lower whole number of shares.  If the Corporation elects not to, or is unable to, make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.

(iv)

Conversion Disputes.   In the case of any dispute with respect to a conversion, the Corporation shall promptly issue such number of shares of Common Stock in accordance with subparagraph (i) above as are not disputed. If such dispute involves the calculation of the Conversion Price, and such dispute is not promptly resolved by discussion between the relevant Holder and the Corporation, the Corporation shall submit the disputed 

4

calculations to an independent outside accountant via facsimile within three Business Days of receipt of the Notice of Conversion. The accountant, at the Corporation's sole expense, shall promptly audit the calculations and notify the Corporation and the Holder of the results no later than three Business Days from the date it receives the disputed calculations. The accountant's calculation shall be deemed conclusive, absent manifest error. The Corporation shall then issue the appropriate number of shares of Common Stock in accordance with subparagraph (i) above,

(v)

Payment of Accrued Amounts.  Upon conversion of any shares of Series A Preferred Stock, all amounts then accrued or payable on such shares under this Certificate of Designation (including, without limitation, all Dividends) or the Registration Rights Agreement through and including the Conversion Date shall be paid by the Corporation in cash or at the Corporation's option in stock, or, in the case of any Dividend, in the manner described in Article III, In the event that the Corporation elects to effect a payment-in-kind, the number of fully paid and nonassessable shares of Common Stock due shall be determined in accordance with the following formula:

All Amounts Accrued or Payable

Conversion Price

V. RESERVATION OF SHARES OF COMMON STOCK

A

Reserved Amount.   On or prior to the Issuance Date, the Corporation shall reserve not less than 15,000,000 shares of its authorized but unissued shares of Common Stock for issuance upon conversion of the Series A Preferred Stock (including any Dividend payable thereon), and, thereafter, the number of authorized but unissued shares of Common Stock so reserved (the "Reserved Amount") shall at all times be sufficient to provide for the full conversion of all of the Series A Preferred Stock (including any Dividend payable thereon) outstanding at the current Conversion Price thereof, and any anticipated adjustments to such Conversion Price.

B

Increases to Reserved Amount. During the period that the Corporation remains privately held and not listed on any recognized stock exchange in the United States or abroad or the OTC Bulletin Board, the Corporation shall, twice annually, review the Reserved Amount for any stock splits, or dividends on the Series A Preferred Stock, or similar situations to determine whether the Reserved Amount needs to be increased

VI. RANK

All shares of the Series A Preferred Stock shall rank (i) senior to the Corporation's Common Stock any other class of securities which is specifically designated as junior to the Series A Preferred Stock (collectively, with the Common Stock, the "Junior Securities"); (ii) senior to or pari passu with any other class or series of Preferred Stock of the Corporation hereafter created specifically ranking, by its terms, on parity with the Series A Preferred Stock (the "Pari Passu Securities"); and (iii) junior to any class or series of capital stock of the Corporation hereafter created (with the written consent of the Majority Holders obtained in accordance with Article IX hereof) specifically ranking, by its terms, senior to the Series A Preferred Stock (collectively, the "Senior Securities"), in each case as to distribution of assets upon liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary.

5

VII. LIQUIDATION PREFERENCE

A.

In the event of a merger, sale (of substantially all assets or stock), any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Corporation, then, either (i) after any distribution or payment on Senior Securities, (ii) simultaneous with any distribution or payment on Pari Passu Securities, and (iii) before any distribution or payment shall be made to the Holders of the Common Stock or any other Junior Securities, each Holder of Series A Preferred Stock then outstanding shall be entitled to be paid, out of the assets of the Corporation available for distribution to its stockholders, an amount (the "Liquidation Preference") equal to (i) aggregate number of shares of Series A Preferred Stock then outstanding multiplied by its Stated Value per share; and (ii) any accrued but unpaid Dividends.  If the assets of the Corporation are not sufficient to generate cash sufficient to pay in full the Liquidation Preference, then the Holders of Series A Preferred Stock shall share ratably (together with holders of any Pari Passu Securities) in any distribution of cash generated by such assets in accordance with the respective amounts that would have been payable in such distribution as if the amounts to which the Holders of outstanding shares of Series A Preferred Stock are entitled were paid in full.

VIII. ADJUSTMENTS

The Conversion Price and the number of Conversion Shares shall be subject to adjustment as follows:

A.

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

B.

Adjustment in Number of Shares.  Upon each adjustment of the Conversion Price pursuant to the provisions of this Article VIII, the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock shall be adjusted by multiplying a number equal to the Conversion Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon exercise of Series A Preferred Stock immediately prior to such adjustment and dividing the product so obtained by the adjusted Conversion Price.

C .

Consolidation, Merger or Sale.  In case of any consolidation of the Corporation with, or merger of the Corporation into any other corporation, or in case of any sale or conveyance of all or substantially all of the assets of the Corporation other than in connection with a plan of complete liquidation of the Corporation, then as a condition of such consolidation, merger or sale or conveyance, adequate provision will be made whereby the Holder of the Series A Preferred Stock will have the right to acquire and receive upon conversion of the Series A Preferred Stock in lieu of the shares of Common Stock immediately theretofore acquirable upon the conversion of the Series A Preferred Stock, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for the number of shares of Common Stock immediately theretofore acquirable and receivable upon conversion of the Series A Preferred 

6

Stock had such consolidation, merger or sale or conveyance not taken place.  In any such case, the Corporation will make appropriate provision to insure that the provisions of this Article VIII hereof will thereafter be applicable as nearly as may be in relation to any shares of stock or securities thereafter deliverable upon the conversion of the Series A Preferred Stock.  The Corporation will not effect any consolidation, merger or sale or conveyance unless prior to the consummation thereof, the successor corporation (if other than the Corporation) assumes by written instrument the obligations under this Article VIII and the obligations to deliver to the Holder of the Series A Preferred Stock such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to acquire.

D.

Distribution of Assets.  In case the Corporation shall declare or make any distribution of its assets (including cash) to holders of Common Stock as a partial liquidating dividend, by way of return of capital or otherwise, then, after the date of record for determining shareholders entitled to such distribution, but prior to the date of distribution, the Holder of the Series A Preferred Stock shall be entitled upon conversion of the Series A Preferred Stock for the purchase of any or all of the shares of Common Stock subject hereto, to receive the amount of such assets which would have been payable to the Holder had the Holder been the holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such distribution.

E.

Adjustment Due to Dilutive Issuance.  If, at any time when any Series A Preferred Stocks are issued and outstanding, the Corporation issues or sells, or in accordance with this Article VIII is deemed to have issued or sold, any shares of Common Stock for no consideration or for a consideration per share (before deduction of reasonable expenses or commissions or underwriting discounts or allowances in connection therewith) less than the Conversion Price in effect on the date of such issuance (or deemed issuance) of such shares of Common Stock (a “Dilutive Issuance”), then immediately upon the Dilutive Issuance, the Conversion Price will be reduced to the price determined by multiplying the Conversion Price in effect immediately prior to the Dilutive Issuance by a fraction, (i) the numerator of which is an amount equal to the sum of (x) the number of shares of Common Stock actually outstanding immediately prior to the Dilutive Issuance, plus (y) the quotient of the aggregate consideration, calculated as set forth in Article VIII, received by the Corporation upon such Dilutive Issuance divided by the Conversion Price in effect immediately prior to the Dilutive Issuance, and (ii) the denominator of which is the Common Stock Deemed Outstanding (as defined below) immediately after the Dilutive Issuance; provided that only one adjustment will be made for each Dilutive Issuance.  The term “Common Stock Deemed Outstanding” shall mean the number of shares of Common Stock actually outstanding (not including shares of Common Stock held in the treasury of the Corporation), plus (i) the maximum total number of shares of Common Stock issuable upon the exercise of Options, as of the date of such issuance or grant of such Options, if any, and (ii) the maximum total number of shares of Common Stock issuable upon conversion or exchange of Convertible Securities, as of the date of issuance of such Convertible Securities, if any.  No adjustment to the Conversion Price shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment.

F.

Effect on Conversion Price of Certain Events.  For purposes of determining the adjusted Conversion Price, the following will be applicable:

(i)

Issuance of Rights or Options.  If the Corporation in any manner issues or grants any warrants, rights or options, whether or not immediately exercisable, to subscribe for or to purchase Common Stock (such rights and options to purchase Common Stock or 

7

Convertible Securities are hereinafter referred to as “Options”) or and the price per share for which Common Stock is issuable upon the exercise of such Options less than the Conversion Price on the date of issuance or grant of such Options, then the maximum total number of shares of Common Stock issuable upon the exercise of all such Options will, as of the date of the issuance or grant of such Options, be deemed to be outstanding and to have been issued and sold by the Corporation for such price per share.  For purposes of the preceding sentence, the “price per share for which Common Stock is issuable upon the exercise of such Options” is determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the issuance or granting of all such Options, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the exercise of all such Options, plus, in the case of Convertible Securities (as hereinafter defined) issuable upon the exercise of such Options, the minimum aggregate amount of additional consideration payable upon the conversion or exchange thereof at the time such Convertible Securities first become convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the exercise of all such Options (assuming full conversion of Convertible Securities, if applicable).  No further adjustment to the Conversion Price will be made upon the actual issuance of such Common Stock upon the exercise of such Options or upon the conversion or exchange of Convertible Securities issuable upon exercise of such Options.

(ii)

Issuance of Convertible Securities.  If the Corporation in any manner issues or sells any other series or classes of Preferred Stock or other securities that are convertible into or exchangeable for Common Stock (“Convertible Securities”), whether or not immediately convertible (other than where the same are issuable upon the exercise of Options) and the price per share for which Common Stock is issuable upon such conversion or exchange is less than the Conversion Price on the date of issuance, then the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities will, as of the date of the issuance of such Convertible Securities, be deemed to be outstanding and to have been issued and sold by the Corporation for such price per share.  For the purposes of the preceding sentence, the “price per share for which Common Stock is issuable upon such conversion or exchange” is determined by dividing (i) the total amount, if any, received or receivable by the Corporation as consideration for the issuance or sale of all such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange thereof at the time such Convertible Securities first become convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities.  No further adjustment to the Conversion Price will be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities.

(iii)

Change in Option Price or Conversion Rate.  If there is a change at any time in (i) the amount of additional consideration payable to the Corporation upon the exercise of any Options; (ii) the amount of additional consideration, if any, payable to the Corporation upon the conversion or exchange of any Convertible Securities; or (iii) the rate at which any Convertible Securities are convertible into or exchangeable for Common Stock (other than under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of such change will 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 additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold.

(iv)

Subdivision or Combination of Common Stock.  If the Corporation at 

8

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

(v)

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

(vi)

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

 (G)

Exceptions to Adjustments.  No adjustment to the Conversion Price or Conversion Shares will be made (A) upon the issuance of shares of Common Stock or Options or Convertible Securities to employees of the Corporation pursuant to any stock or option plan duly adopted by the Board of Directors of the Corporation; or (B) the issuance of shares of Common Stock, Convertible Securities or Optionis in connection with any merger with any other Person, or as full or partial consideration for the acquisition of the securities or assets of any other Person, whether by merger, tender offer, asset purchase, stock purchase, or like combination or consolidation (a “Business Combination”).

(H)

Notice of Adjustment.  Upon the occurrence of any event which requires any adjustment of the Conversion Price, then, and in each such case, the Corporation shall give notice thereof to the Holder of the Series A Preferred Stock, which notice shall state the Conversion Price resulting from such adjustment and the increase or decrease in the number of Class A Conversion Shares purchasable at such price upon exercise, setting forth in reasonable detail the 

9

method of calculation and the facts upon which such calculation is based.  Such calculation shall be certified by the Chief Financial Officer of the Corporation.

(I)

Minimum Adjustment of Conversion Price.  No adjustment of the Conversion Price shall be made in an amount of less than 1% of the Conversion Price in effect at the time such adjustment is otherwise required to be made, but any such lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to not less than 1% of such Conversion Price.

(J)

No Fractional Shares.  No fractional shares of Common Stock are to be issued upon the conversion of the Series A Preferred Stock, but the Corporation shall pay a cash adjustment in respect of any fractional share which would otherwise be issuable in an amount equal to the same fraction of the average Market Price per share of the Common Stock for the five (5) Trading Days immediately prior to the date of such exercise.

(K)

Other Notices.  In case at any time:

(i)

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

(ii)

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

(iii)

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

(iv)

there shall be a voluntary or involuntary dissolution, liquidation or winding up of the Corporation;

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

CLASS A STOCK PURCHASE CLASS A WARRANT

THIS CERTIFIES THAT, for value received, _______________________________, or its registered assigns, (the “Holder”) is entitled to purchase from VISCORP, INC. (to be renamed Tianyin Pharmaceutical Co., Inc.), a Delaware corporation, (the “Company”), at any time or from time to time during the period specified in Section 2 hereof, that that number of shares of the Company’s Common Stock, without par value per share (the “Common Stock”), as shall be equal to fifty percent (50%) of the number of shares of Common Stock (the “Conversion Shares”) that are issuable upon conversion of the amount of Series A Preferred Stock of the Company to be received by the Holder in exchange for his or its Note, all pursuant to the terms and conditions of the “Securities Purchase Agreement” (as hereinafter defined), at an exercise price of equal to (U.S.) $2.50 per share (the “Exercise Price”). 

As used herein, the term “Class A Warrant Shares” shall mean the shares of Common Stock that are purchasable hereunder.  The number of Class A Warrant Shares and the Exercise Price per Class A Warrant Share are subject to adjustment as provided in Section 4 hereof.  The term “Class A Warrants” means this Class A Warrant and the other Class A Warrants issued pursuant to that certain Securities Purchase Agreement, dated as of January 16, 2008, by and among the Company, the Corporate Parties thereto, the Viscorp Principal Stockholder and the Investors listed on the execution page thereof (the “Securities Purchase Agreement”). 

As provided in the Securities Purchase Agreement, in the event that the Series A Preferred Stock Issuance is not consummated by April 30, 2008, this Class A Warrant may be exercised to purchase that number of Class A Warrant Shares as shall be equal to 100% of the number of Conversion Shares that would otherwise have been issuable upon conversion of the Series A Preferred Stock if such Series A Preferred Stock had been exchanged for the Note at any time on or after May 1, 2008, all in accordance with the provisions of Section 7c(iv) of the Securities Purchase Agreement. 

Unless otherwise defined in this Class A Warrant, all capitalized terms, when used herein, shall have the same meaning as is defined in the Securities Purchase Agreement.

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

1.

Manner of Exercise.

a.

Procedure.  Subject to the provisions hereof, this Class A Warrant may be exercised by the Holder, in whole or in part, by the surrender of this Class A Warrant, together with a completed exercise agreement in the form attached hereto (the “Exercise Agreement”), to the Company during normal business hours on any day that banks are generally open for business in New York City (a “Business Day”) at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the Holder), and upon (i) payment to the Company in cash, by certified or official bank check or by wire transfer for the account of the Company of the Exercise Price for the Class A Warrant Shares specified in the Exercise Agreement or (ii) if by June 30, 2008, the Class A Warrant Shares have not been registered for resale by the Holder pursuant to an effective registration statement under the Securities Act of 1933, as amended, (the “Securities Act”) or under applicable state securities laws, by delivery to the Company of a written notice of an election to effect a Cashless Exercise (as defined in Section 1(c) below) for the Class A Warrant Shares specified in the Exercise Agreement; provided, however, that the ability of the Holder to utilize the Cashless Exercise provisions of this Class A Warrant shall cease as soon as the Class A Warrant Shares shall have been registered for resale pursuant to an effective registration statement.  The Class A Warrant Shares so purchased shall be deemed to be issued to the Holder or such Holder’s designee, as the record owner of such shares, as of the close of business on the date on which the completed Exercise Agreement shall have been delivered, and payment shall have been made for such shares as set forth above.  Certificates for the Class A Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall be delivered to the Holder (without restrictive legend thereon when such exercise occurs while a registration statement registering under the Securities Act the resale of the Class A Warrant Shares so purchased is effective or such Class A Warrant Shares so purchased may be resold by the Holder pursuant to Rule 144(k) or any similar successor rule) within a reasonable time, not exceeding three (3) Business Days, after this Class A Warrant shall have been so exercised.  The certificates so delivered shall be in such denominations as may be requested by the Holder and shall be registered in the name of the Holder or such other name as shall be designated by the Holder.  If this Class A Warrant shall have been exercised only in part, then, at the option of the Holder (i) the Holder may surrender this Class A Warrant to the Company and, unless this Class A Warrant has expired, the Company shall, at its expense, within a reasonable time, not exceeding three (3) Business Days, after this Class A Warrant shall have been so exercised, deliver to the Holder a new Class A Warrant representing the number of shares with respect to which this Class A Warrant shall not then have been exercised, or (ii) the Holder may retain this Class A Warrant and the Class A Warrant Shares purchasable under this Class A Warrant shall be reduced by such number of Class A Warrant Shares so exercised by the Holder and properly delivered by the Company hereunder.

b.

Exercise Limit.  In no event, at any time that the Company has any class of its securities registered under Section 12(b) or Section 12(g) of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”), shall the Holder of this Class A Warrant be entitled to exercise any portion of this Class A Warrant in excess of that portion of this Class A Warrant upon exercise of which the sum of (i) the number of shares of Common 

2

Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unexercised portion of this Class A Warrant and the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein) and (ii) the number of shares of Common Stock issuable upon exercise of the portion of this Class A Warrant with respect to which the determination described herein is being made, would result in beneficial ownership by the Holder and its affiliates of more than 9.99% of the outstanding shares of Common Stock.  For purposes of this Section 1(b), beneficial ownership shall be determined in accordance with Section 13(d) of Exchange Act and Regulation 13D-G thereunder, except as otherwise provided in clause (i) of the preceding sentence.  The Holder may waive the provisions of this Section 1(b) as to itself (and solely as to itself) upon not less than 61 days’ prior notice to the Company, and the provisions of this Section 1(b) shall continue to apply until such 61st day (or such later date as may be specified in such notice of waiver).  No exercise in violation of this Section 1(b), but otherwise in accordance with this Class A Warrant, shall affect the status of the Common Stock issued upon such exercise as validly issued, fully-paid and nonassessable.

c.

Cashless Exercise.

In the event (and only in the event) that, by 5:00 p.m. (Eastern Standard Time) on June 30, 2008, the resale of the Class A Warrant Shares by the Holder shall have not registered pursuant to an effective registration statement under the Securities Act, then the Holder may exercise this Class A Warrant in whole or in part by presentation and surrender of this Class A Warrant to the Company at its principal executive offices, with a written notice of the Holders intention to effect a cashless exercise, including a calculation of the number of share of Common Stock to be issued upon such exercise in accordance with the terms hereof (a “Cashless Exercise”).  In the event of a Cashless Exercise, in lieu of paying the Exercise Price in cash, the Holder shall surrender this Class A Warrant for that number of shares of Common Stock determined by multiplying the number of Class A Warrant Shares to which such Holder would otherwise be entitled by a fraction (i) the numerator of which shall be the difference between (A) the average Market Price (as defined in Section 4) per share of the Common Stock for the five (5) Trading Days (as defined in Section 4) immediately prior to the date the completed Exercise Agreement shall have been delivered to the Company (the “Cashless Exercise Market Price”) and (B) the Exercise Price, and (ii) the denominator of which shall be the Cashless Exercise Market Price.

2.

Period of Exercise.

This Class A Warrant is exercisable at any time or from time to time on or after February 1, 2008 and before 6:00 p.m., New York, New York time on January 31, 2013 (the “Exercise Period”).

3.

Certain Agreements of the Company.  

The Company hereby covenants and agrees as follows:

a.

Shares to be Fully Paid.  All Class A Warrant Shares will, upon issuance in accordance with the terms of this Class A Warrant, be validly issued, fully paid, and nonassessable and free from all taxes, liens, and charges with respect to the issue thereof.

b.

Reservation of Shares.  During the Exercise Period, the Company shall at all times have authorized, and reserved for the purpose of issuance upon exercise of this 

3

Class A Warrant, a sufficient number of shares of Common Stock to provide for the exercise of this Class A Warrant.

c.

Listing.  If the Company’s Common Stock is listed as of the date of this Class A Warrant, or if so listed in the future, the Company shall maintain its listing of its Common Stock on each national securities exchange or automated quotation system, as the case may be, and shall maintain such listing of any other shares of capital stock of the Company issuable upon the exercise of this Class A Warrant if and so long as any shares of the same class shall be listed on such national securities exchange or automated quotation system.

d.

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

e.

Successors and Assigns.  This Class A Warrant will be binding upon any entity succeeding to the Company by merger, consolidation, or acquisition of all or substantially all the Company’s assets.

f.

Delivery of Common Stock by Electronic Transfer.  In lieu of delivering physical certificates representing the Common Stock issuable upon exercise, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program and the Company has activated such programs, upon request of the Holder and its compliance with the provisions contained in Section 1, the Company shall use its best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon exercise to the Holder by crediting the account of Holder’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission system.

4.

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

a.

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

4

reclassification or otherwise) the shares of Common Stock acquirable hereunder into a smaller number of shares, then, after the date of record for effecting such combination, the Exercise Price in effect immediately prior to such combination will be proportionately increased.

b.

Adjustment in Number of Shares.  Upon each adjustment of the Exercise Price pursuant to the provisions of this Section 4, the number of shares of Common Stock issuable upon exercise of this Class A Warrant shall be adjusted by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon exercise of this Class A Warrant immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price.

c.

Consolidation, Merger or Sale.  In case of any consolidation of the Company with, or merger of the Company into any other corporation, or in case of any sale or conveyance of all or substantially all of the assets of the Company other than in connection with a plan of complete liquidation of the Company, then as a condition of such consolidation, merger or sale or conveyance, adequate provision will be made whereby the Holder of this Class A Warrant will have the right to acquire and receive upon exercise of this Class A Warrant in lieu of the shares of Common Stock immediately theretofore acquirable upon the exercise of this Class A Warrant, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for the number of shares of Common Stock immediately theretofore acquirable and receivable upon exercise of this Class A Warrant had such consolidation, merger or sale or conveyance not taken place.  In any such case, the Company will make appropriate provision to insure that the provisions of this Section 4 hereof will thereafter be applicable as nearly as may be in relation to any shares of stock or securities thereafter deliverable upon the exercise of this Class A Warrant.  The Company will not effect any consolidation, merger or sale or conveyance unless prior to the consummation thereof, the successor corporation (if other than the Company) assumes by written instrument the obligations under this Section 4 and the obligations to deliver to the Holder of this Class A Warrant such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to acquire.

d.

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

e.

Adjustment Due to Dilutive Issuance.  If, at any time when any Class A Warrants are issued and outstanding, the Company issues or sells, or in accordance with this Section 4e or Section 4f is deemed to have issued or sold, any shares of Common Stock for no consideration or for a consideration per share (before deduction of reasonable expenses or commissions or underwriting discounts or allowances in connection therewith) less than the Exercise Price in effect on the date of such issuance (or deemed issuance) of such shares of Common Stock (a “Dilutive Issuance”), then immediately upon the Dilutive Issuance, the Exercise Price will be reduced to the price determined by multiplying the Exercise Price in effect 

5

immediately prior to the Dilutive Issuance by a fraction, (A) the numerator of which is an amount equal to the sum of (x) the number of shares of Common Stock actually outstanding immediately prior to the Dilutive Issuance, plus (y) the quotient of the aggregate consideration, calculated as set forth in Section 4f, received by the Company upon such Dilutive Issuance divided by the Exercise Price in effect immediately prior to the Dilutive Issuance, and (B) the denominator of which is the Common Stock Deemed Outstanding (as defined below) immediately after the Dilutive Issuance; provided that only one adjustment will be made for each Dilutive Issuance.  The term “Common Stock Deemed Outstanding” shall mean the number of shares of Common Stock actually outstanding (not including shares of Common Stock held in the treasury of the Company), plus (i) the maximum total number of shares of Common Stock issuable upon the exercise of Options, as of the date of such issuance or grant of such Options, if any, and (ii) the maximum total number of shares of Common Stock issuable upon conversion or exchange of Convertible Securities, as of the date of issuance of such Convertible Securities, if any.  No adjustment to the Exercise Price shall have the effect of increasing the Exercise Price above the Exercise Price in effect immediately prior to such adjustment.

Notwithstanding the foregoing the issuance of Common Stock of the Company upon conversion of its Series A Preferred Stock shall not be deemed to be a Dilutive Issuance for the purposes of this Class A Warrant.

f.

Effect on Exercise Price of Certain Events.  For purposes of determining the adjusted Exercise Price, the following will be applicable:

1)

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

6

2)

Issuance of Convertible Securities.  If the Company in any manner issues or sells any Convertible Securities, whether or not immediately convertible (other than where the same are issuable upon the exercise of Options) and the price per share for which Common Stock is issuable upon such conversion or exchange is less than the Exercise Price on the date of issuance, then the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities will, as of the date of the issuance of such Convertible Securities, be deemed to be outstanding and to have been issued and sold by the Company for such price per share.  For the purposes of the preceding sentence, the “price per share for which Common Stock is issuable upon such conversion or exchange” is determined by dividing (i) the total amount, if any, received or receivable by the Company as consideration for the issuance or sale of all such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof at the time such Convertible Securities first become convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities.  No further adjustment to the Exercise Price will be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities.

3)

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

4)

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

5)

Treatment of Expired Options and Unexercised Convertible Securities.  If, in any case, the total number of shares of Common Stock issuable upon exercise of any Option or upon conversion or exchange of any Convertible Securities is not, in fact, issued and the rights to exercise such Option or to convert or exchange such Convertible Securities shall have expired or terminated, the Exercise Price then in effect will be readjusted to the Exercise Price which would have been in effect at the time of such expiration or termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such 

7

expiration or termination (other than in respect of the actual number of shares of Common Stock issued upon exercise or conversion thereof), never been issued.

6)

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

7)

Exceptions to Adjustment of Exercise Price.  No adjustment to the Exercise Price will be made (A) upon the issuance of shares of Common Stock or options or Class A Warrants to purchase Common Stock to employees of the Company pursuant to any stock or option plan duly adopted by the Board of Directors of the Company on or before June 14, 2006, or (B) the issuance of shares of Common Stock upon conversion of any of the Notes issued under the Securities Purchase Agreement.

g.

Notice of Adjustment.  Upon the occurrence of any event which requires any adjustment of the Exercise Price, then, and in each such case, the Company shall give notice thereof to the Holder of this Class A Warrant, which notice shall state the Exercise Price resulting from such adjustment and the increase or decrease in the number of Class A Warrant Shares purchasable at such price upon exercise, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.  Such calculation shall be certified by the Chief Financial Officer of the Company.

h.

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

i.

No Fractional Shares.  No fractional shares of Common Stock are to be issued upon the exercise of this Class A Warrant, but the Company shall pay a cash adjustment in respect of any fractional share which would otherwise be issuable in an amount equal to the same fraction of the average Market Price per share of the Common Stock for the five (5) Trading Days immediately prior to the date of such exercise.

8

j.

Other Notices.  In case at any time:

i.

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

ii.

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

iii.

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