SECURED CONVERTIBLE NOTE



          FOR VALUE RECEIVED, CERAGENIX PHARMACEUTICALS, INC., a Delaware corporation (hereinafter called "Borrower"), hereby promises to pay to ____________________________, ____________________________________________________________ (the "Holder") or order, without demand, the sum of ________________________________________ Dollars ($_________), with unpaid accrued interest, on November ___, 2007 (the "Maturity Date"), or sooner as described herein.


          This Note has been entered into pursuant to the terms of a subscription agreement between the Borrower and the Holder, dated of even date herewith (the "Subscription Agreement"), and shall be governed by the terms of such Subscription Agreement.  Unless otherwise separately defined herein, all capitalized terms used in this Note shall have the same meaning as is set forth in the Subscription Agreement.  The following terms shall apply to this Note:


ARTICLE I

GENERAL PROVISIONS


          1.1          Interest Rate.   Subject to Section 5.6 hereof, interest payable on this Note shall accrue at a rate per annum (the "Interest Rate") equal to ten percent (10%) per year on the outstanding principal balance, compounded annually.   Interest on the Principal Amount shall first be payable on the sooner of 120 days after the Issue Date, or five Business Days after the Actual Effective Date and on the same day of the month each three months thereafter and on the Maturity Date, whether by acceleration or otherwise.  Provided an Event of Default has not occurred and interest is paid timely, the Borrower may pay one-half the interest payable on this Note with registered free-trading shares of Common Stock with an attributed value per share equal to 85% of the volume weighted average price of the Common Stock as reported by Bloomberg L.P. for the Principal Market for the five consecutive trading days ending on the trading day preceding the date interest is due to be paid hereunder.  Interest shall compound annually.  This Note may be pre-paid at any time without penalty in accordance with the terms of Section 2.5 hereof.


          1.2          Conversion Privileges.  The Conversion Privileges set forth in Article II shall remain in full force and effect immediately from the date hereof and until the Note is paid in full regardless of the occurrence of an Event of Default.  The Note shall be payable in full on the Maturity Date, unless previously converted into Common Stock in accordance with Article II hereof, provided, that if an Event of Default has occurred, the Holder may extend the Maturity Date for up to a time period equal to the duration of the Event of Default.


          1.3          Default Interest Rate.   A default interest rate of fifteen percent (15%) per annum shall apply to amounts owed hereunder which are not paid on their respective due dates.


ARTICLE II

CONVERSION RIGHTS


          The Holder shall have the right to convert the outstanding principal and interest due under this Note into Shares of the Borrower's Common Stock, no par value per share ("Common Stock") as set forth below.


                    2.1.          Conversion into the Borrower's Common Stock.


                    (a)          Subject to the terms of this Note, the Holder shall have the right from and after the date of the issuance of this Note and then at any time until this Note is fully paid, to convert any outstanding and unpaid principal portion of this Note, and accrued interest, at the election of the Holder (the date of giving of such notice of conversion being a "Conversion Date") into fully paid and nonassessable shares of Common Stock as such stock exists on the date of issuance of this Note, or any shares of capital stock of Borrower into which such Common Stock shall hereafter be changed or reclassified, at the conversion price as defined in Section 2.1(b) hereof (the "Conversion Price"), determined as provided herein.  Upon delivery to the Borrower of a completed Notice of Conversion, a form of which is annexed hereto, Borrower shall issue and deliver to the Holder within three (3) business days from the Conversion Date (such third day being the "Delivery Date") that number of shares of Common Stock for the portion of the Note converted in accordance with the foregoing.  At the election of the Holder, the Borrower will deliver accrued but unpaid interest on the Note through the Conversion Date directly to the Holder on or before the Delivery Date.  The number of shares of Common Stock to be issued upon each conversion of this Note shall be determined by dividing that portion of the principal of the Note and interest to be converted, by the Conversion Price.


                    (b)          Subject to adjustment as provided in this Section 2.1(b) and Section 2.1(c) hereof, the Conversion Price per share shall be $____ [the lesser of $2.05, or the average of the Volume Weighted Average Prices of the Common Stock as reported by Bloomberg L.P. for the OTC Bulletin board for the twenty trading days ending on the last trading day before the Closing Date] per share of Common Stock, subject to adjustment as described herein.  From and after (i) the occurrence of an Event of Default, or (ii) the occurrence of a Milestone Default (as defined below), the Conversion Price shall be reduced (but not increased) to the lesser of the Conversion Price in effect prior to the occurrence of the Milestone Default or the average of the volume weighted average prices of the Common Stock as reported by Bloomberg L.P. for the Principal Market for the five trading days preceding the Reporting Date (as defined below).  A Milestone Default shall occur if the Borrower does not report as of a Reporting Date on a Form 10-Q, 10-QSB, 10-K or 10-KSB (or successor forms, each a "Form") Revenues and EBITDA equal or greater than the amounts set forth on Schedule A hereto, for any one or more of the periods as set forth on Schedule A hereto.  The Reporting Date shall be the last date the Form is required to be filed after permitted extensions or, if sooner, the date the Form is actually filed.


                    (c)           The Conversion Price and number and kind of shares or other securities to be issued upon conversion determined pursuant to Section 2.1(a), shall be subject to adjustment from time to time upon the happening of certain events while this conversion right remains outstanding, as follows:


                              A.          Merger, Sale of Assets, etc.  If the Borrower at any time shall consolidate with or merge into or sell or convey all or substantially all its assets to any other corporation, this Note, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase such number and kind of shares or other securities and property as would have been issuable or distributable on account of such consolidation, merger, sale or conveyance, upon or with respect to the securities subject to the conversion or purchase right immediately prior to such consolidation, merger, sale or conveyance as if the Holder had converted this Note immediately prior to such event.  The foregoing provision shall similarly apply to successive transactions of a similar nature by any such successor or purchaser.  Without limiting the generality of the foregoing, the anti-dilution provisions of this Section shall apply to such securities of such successor or purchaser after any such consolidation, merger, sale or conveyance.


                              B.          Reclassification, etc.  If the Borrower at any time shall, by reclassification or otherwise, change the Common Stock into the same or a different number of securities of any class or classes that may be issued or outstanding, this Note, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change as if the Holder had converted this Note immediately prior to such event.


                              C.          Stock Splits, Combinations and Dividends.  If the shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, or if a dividend is paid on the Common Stock in shares of Common Stock, the Conversion Price shall be proportionately reduced in case of subdivision of shares or stock dividend or proportionately increased in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately before such event bears to the total number of shares of Common Stock outstanding immediately after to such event..


                              D.          Share Issuance.   So long as this Note is outstanding, if the Borrower shall issue or agree to issue any shares of Common Stock except for the Excepted Issuances for a consideration less than the Conversion Price in effect at the time of such issue, then, and thereafter successively upon each such issue, the Conversion Price shall be reduced to such other lower issue price.  For purposes of this adjustment, the issuance of any security carrying the right to convert such security into shares of Common Stock or of any warrant, right or option to purchase Common Stock shall result in an adjustment to the Conversion Price upon the issuance of the above-described security and again upon the issuance of shares of Common Stock upon exercise of such conversion or purchase rights if such issuance is at a price lower than the then applicable Conversion Price.  The reduction of the Conversion Price described in this paragraph is in addition to other rights of the Holder described in this Note and the Subscription Agreement.


                    (d)          Whenever the Conversion Price is adjusted pursuant to Section 2.1(c) above, the Borrower shall promptly mail to the Holder a notice setting forth the Conversion Price after such adjustment and setting forth a statement of the facts requiring such adjustment.


                    (e)          During the period the conversion right exists, Borrower will reserve from its authorized and unissued Common Stock not less than 175% of the number of shares of Common Stock issuable upon the full conversion of this Note.  Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable.  Borrower agrees that its issuance of this Note shall constitute full authority to its officers, agents, and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Note.


                    2.2          Method of Conversion.  This Note may be converted by the Holder in whole or in part as described in Section 2.1(a) hereof and the Subscription Agreement.  Upon partial conversion of this Note, a new Note containing the same date and provisions of this Note shall, at the request of the Holder, be issued by the Borrower to the Holder for the principal balance of this Note and interest which shall not have been converted or paid.


                    2.3          Maximum Conversion.  The Holder shall not be entitled to convert on a Conversion Date that amount of the Note in connection with that number of shares of Common Stock which would be in excess of the sum of (i) the number of shares of Common Stock beneficially owned by the Holder and its affiliates on a Conversion Date, (ii) any Common Stock issuable in connection with the unconverted portion of the Note, and (iii) the number of shares of Common Stock issuable upon the conversion of the Note with respect to which the determination of this provision is being made on a Conversion Date, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock of the Borrower on such Conversion Date.  For the purposes of this Section 2.3, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder.  Subject to the foregoing, the Holder shall not be limited to aggregate conversions of only 4.99% and aggregate conversion by the Holder may exceed 4.99%.  The Holder shall have the authority and obligation to determine whether the restriction contained in this Section 2.3 will limit any conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Notes are convertible shall be the responsibility and obligation of the Holder.  The Holder may waive the conversion limitation described in this Section 2.3, in whole or in part, upon and effective after 61 days prior written notice to the Borrower.  The Holder may decide whether to convert a Note or exercise this Warrant to achieve an actual 4.99% ownership position.


                    2.4.          Mandatory Conversion.  Provided an Event of Default (or an event that with the passage of time or the giving of notice could become an Event of Default) has not occurred, whether or not such Event of Default has been cured, then commencing after the Actual Effective Date, the Borrower will have the option by written notice to the Holder ("Notice of Mandatory Conversion") of compelling the Holder to convert the outstanding and unpaid Principal Amount, and accrued interest, of this Note into Common Stock at the Conversion Price then in affect ("Mandatory Conversion"). The Notice of Mandatory Conversion must be given, if at all, within ten (10) days following any consecutive twenty (20) day trading period ("Lookback Period") during which the closing bid price for the Borrower's Common Stock as reported by Bloomberg, LP for the Principal Market is more than 200% of the Conversion Price each day during the Lookback Period. The date the Notice of Mandatory Conversion is given is the "Mandatory Conversion Date." The Notice of Mandatory Conversion shall specify the aggregate principal amount of the Note which is subject to Mandatory Conversion.  Mandatory Conversion Notices must be given proportionately to all Holders of Notes who hold Notes similar in terms and tenure as this Note.  A Notice of Mandatory Conversion may not be given unless the Registration Statement has been effective for the unrestricted public resale of the Registrable Securities each day during the Lookback Period and for the three trading days thereafter.  Notices of Mandatory Conversion may not be given in connection with the aggregate amount of Common Stock that would exceed 20% of the amount of Common Stock traded on the Principal Market during the Lookback Period as reported by Bloomberg L.P.  The amount of Note principal included in a Mandatory Conversion Notice shall be further reduced to an amount that would not cause the Holder to exceed the limitation described in Section 2.3 of this Note.  A further Mandatory Conversion Notice may not be given until twenty (20) trading days have elapsed from the preceding Mandatory Conversion Date.  Each Mandatory Conversion Date shall be a deemed Conversion Date and the Borrower will be required to deliver the Common Stock issuable pursuant to a Mandatory Conversion Notice in the same manner and time period as described in Section 2.1 above.


                    2.5.          Optional Redemption of Principal Amount.  From and after the Actual Effective Date (as defined in the Subscription Agreement) and provided an Event of Default (or an event that with the passage of time or the giving of notice could become an Event of Default) has not occurred, whether or not such Event of Default has been cured, unless waived by the Holders, the Borrower will have the option of prepaying the outstanding and unpaid Principal amount, and accrued interest, of this Note ("Optional Redemption"), in whole or in part, by paying to the Holder a sum of money equal to one hundred and twenty percent (120%) of the principal amount to be redeemed, together with accrued but unpaid interest thereon and any and all other sums due, accrued or payable to the Holder arising under this Note or any Transaction Document through the Redemption Payment Date as defined below (the "Redemption Amount").  Borrower's election to exercise its right to prepay must be by notice in writing ("Notice of Redemption").  The Notice of Redemption shall specify the date for such Optional Redemption (the "Redemption Payment Date"), which date shall be thirty (30) days after the date of the Notice of Redemption (the "Redemption Period"). A Notice of Redemption shall not be effective with respect to any portion of the Principal Amount for which the Holder has a pending election to convert; for conversions initiated or made by the Holder during the Redemption Period; nor for principal and interest amounts, the conversion of which would exceed the limits set forth in Section 2.3 of this Note. On the Redemption Payment Date, the Redemption Amount, less any portion of the Redemption Amount against which the Holder had exercised its conversion rights shall be paid in good funds to the Holder. In the event the Borrower fails to pay the Redemption Amount on the Redemption Payment Date as set forth herein, then at the election of the Holder (i) such Notice of Redemption will be null and void, (ii) Borrower will not have the right to deliver another Notice of Redemption, and (iii) Borrower's failure may be deemed by Holder to be non-curable Event of Default.  A Redemption Notice may be given only at a time when the Registration Statement is effective.


ARTICLE III

EVENT OF DEFAULT


          The occurrence of any of the following events of default ("Event of Default") shall, at the option of the Holder hereof, make all sums of principal and interest (to the extent accrued) then remaining unpaid hereon and all other amounts payable hereunder immediately due and payable, upon demand, without presentment, or grace period, all of which hereby are expressly waived, except as set forth below:

This Note is secured by a security interest granted to the Collateral Agent for the benefit of the Holder pursuant to a Security Agreement, as delivered by Borrower to Holder.  The Borrower acknowledges and agrees that should a proceeding under any bankruptcy or insolvency law be commenced by or against the Borrower, or if any of the Collateral (as defined in the Security Agreement) should become the subject of any bankruptcy or insolvency proceeding, then the Holder should be entitled to, among other relief to which the Holder may be entitled under the Transaction Documents and any other agreement to which the Borrower and Holder are parties (collectively, "Loan Documents") and/or applicable law, an order from the court granting immediate relief from the automatic stay pursuant to 11 U.S.C.

The Borrower hereby consents to any motion for relief from stay that may be filed by the Holder in any bankruptcy or insolvency proceeding initiated by or against the Borrower and, further, agrees not to file any opposition to any motion for relief from stay filed by the Holder.  The Borrower represents, acknowledges and agrees that this provision is a specific and material aspect of the Loan Documents, and that the Holder would not agree to the terms of the Loan Documents if this waiver were not a part of this Note. The Borrower further represents, acknowledges and agrees that this waiver is knowingly, intelligently and voluntarily made, that neither the Holder nor any person acting on behalf of the Holder has made any representations to induce this waiver, that the Borrower has been represented (or has had the opportunity to he represented) in the signing of this Note and the Loan Documents and in the making of this waiver by independent legal counsel selected by the Borrower and that the Borrower has discussed this waiver with counsel.

ARTICLE V

MISCELLANEOUS


                    5.1          Failure or Indulgence Not Waiver.  No failure or delay on the part of Holder hereof in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege.
