The estimated portions of the shares of Common Stock of the Issuer and the Second Replacement Credit Opportunities Note distributed pursuant to the Redemption Agreements (the “Estimated Allocation”) were disclosed in Amendment No. 5. Immediately following the Securities Distribution, as of July 16, 2012, the Credit Opportunities Fund did not beneficially own any securities of the Issuer.

Pursuant to the terms of the First Amendment, (i) on September 21, 2012, the Issuer issued and sold to the VPC Onshore Fund a Senior Secured Convertible Note in the aggregate principal amount of $4,000,000 (the “First Amendment VPC Onshore Fund Note”), with a conversion price of $0.05 per share, for a purchase price of $4,000,000, and (ii) on September 24, 2012, the Initial Delaware Fund Note, the Initial Cayman Fund Note, the Second Replacement VPC Note and the Initial VPC Offshore Note, which each had a conversion price of $0.70 per share (subject to adjustment as set forth therein), were each reissued by the Issuer to the applicable Fund with a conversion price of $0.15 per share (subject to adjustment as set forth therein) (the Initial Delaware Fund Note, as so reissued, the “Reissued Delaware Fund Note”; the Initial Cayman Fund Note, as so reissued, the “Reissued Cayman Fund Note”; the Second Replacement VPC Note, as so reissued, the “Reissued VPC Onshore Fund Note”; and the Initial VPC Offshore Note, as so reissued, the “Reissued VPC Offshore Fund Note” and, together with the Reissued Delaware Fund Note, the Reissued Cayman Fund Note and the Reissued VPC Onshore Fund Note, the “Reissued Notes” and, together with the First Amendment VPC Onshore Fund Note, the “Existing Convertible Notes”). Pursuant to the Security Documents (as defined in the Amended and Restated Financing Agreement), the Existing Convertible Notes are secured by a first priority lien on all current and future assets of the Issuer.

As disclosed in Amendment No. 7, on December 19, 2012, Jacob Capital transferred and assigned to RNL VPC all of the outstanding equity interests held by it in each of GP I and GP II (the “GP Interest Transfer”).

On December 28, 2012, Richard Levy made a gift of approximately 22% of the outstanding non-voting interests in RNL VPC to a trust established for the benefit of his minor child.

On April 8, 2013 the Funds, the Agent and the Issuer entered into a Second Amendment to the Amended and Restated Financing Agreement (the “Second Amendment”). Pursuant to the terms of the Second Amendment, on April 8, 2013, the Issuer issued and sold to the VPC Onshore Fund a Senior Secured Convertible Note in the aggregate principal amount of $750,000 (the “Second Amendment Note” and, together with the Existing Convertible Notes and the Re-Loan Note (as defined below), the “Convertible Notes”), with a conversion price of $0.09 per share (subject to adjustment as set forth therein) for a purchase price of $750,000. The Issuer received a net amount of $700,000 from the VPC Onshore Fund after the Issuer deposited $50,000 with the Agent, which amount will be used to reimburse the Funds and the Agent for fees, costs and expenses incurred by the Funds and the Agent in connection with the Second Amendment and all transactions contemplated thereby. Pursuant to the Security Documents, the Second Amendment Note is secured by a first priority lien on all current and future assets of the Issuer. The maturity date of the Second Amendment Note is the earlier of (i) June 7, 2013 and (ii) such earlier date as the unpaid principal balance of the Second Amendment Note becomes due and payable pursuant to the terms of the Second Amendment Note. The Issuer took such steps as were necessary to cause the transactions contemplated by the Second Amendment, including the deemed issuance of the shares of Common Stock issuable to the VPC Onshore Fund upon conversion of the Second Amendment Note, to be exempt from Section 16(b) of the Act, pursuant to Rule 16b-3 thereunder.

On April 16, 2013, as a result one or more events of default occurring and continuing under the Amended and Restated Financing Agreement, the Agent, pursuant to the terms of the Amended and Restated Financing Agreement, the Security Documents and Section 5/9-610 of the Illinois Uniform Commercial Code, for the benefit of the Funds, held a public auction (the “Article 9 Auction”) for the sale of all of the personal property and assets (the “Biotechnology Assets”) pledged as collateral under the Amended and Restated Financing Agreement that related to the Issuer’s biotechnology business (the “Biotechnology Business”). At the Article 9 Auction, the Funds made a credit bid in an aggregate amount of $15 million outstanding under the Reissued Notes and were deemed to be the highest bidder for the Biotechnology Assets.

As disclosed in Amendment No. 8, on April 25, 2013, the Biotechnology Assets were transferred to the Funds in consideration of the satisfaction and discharge of an aggregate of $15 million outstanding under the Reissued Notes (the “Article 9 Sale”) consisting of the discharge of (i) $1,930,175 of principal and $2,688,006 of accrued but unpaid interest outstanding under the Reissued Delaware Fund Note, (ii) $1,705,221 of principal and $2,374,729 of accrued but unpaid interest outstanding under the Reissued Cayman Fund Note, (iii) $2,414,474 of principal and $1,466,011 of accrued but unpaid interest outstanding under the Reissued VPC Onshore Fund Note, and (iv) $1,012,021 of principal and $1,409,363 of accrued but unpaid interest outstanding under the Reissued VPC Offshore Fund Note.

The Issuer took such steps as were necessary to cause the transactions contemplated by the Article 9 Sale, including any deemed disposition of the shares of Common Stock issuable to the Funds upon conversion of the portion of the Reissued Notes that were satisfied and discharged in consideration of the Biotechnology Assets, to be exempt from Section 16(b) of the Act, pursuant to Rule 16b-3 thereunder.

Immediately following the Article 9 Sale, an aggregate of $36,754,718.50 remained outstanding under the Reissued Notes, consisting of (i) $12,907,024.14 of principal outstanding under the Reissued Delaware Fund Note, (ii) $11,402,759.42 of principal outstanding under the Reissued Cayman Fund Note, (iii) $5,677,580.91 of principal outstanding under the Reissued VPC Onshore Fund Note and (iv) $6,767,354.04 of principal outstanding under the Reissued VPC Offshore Fund Note. Pursuant to the Security Documents, the Convertible Notes are secured by a first priority lien on all assets of the Issuer that were not sold pursuant to the Article 9 Sale and all future assets of the Issuer.

Following the consummation of the Article 9 Sale, the Funds contributed the Biotechnology Assets to Enteris BioPharma, Inc., an affiliate of the Funds.

On May 1, 2013, the Issuer granted to Mr. Levy a stock option to purchase 75,000 shares of Common Stock (the “2013 Option” and, together with the 2010 Option, the 2011 Option and the 2012 Option, the “Options”). The exercise price of the 2013 Option is $0.0354 per share of Common Stock. The 2013 Option will become exercisable on May 1, 2014 and will expire on April 30, 2023.

On May 14, 2013, the Issuer used the proceeds from the sale of its interest in Nu-Co Development GmbH to prepay an aggregate of $1,000,000 outstanding under the Existing Notes. Immediately following the prepayment, VPC Onshore Fund re-loaned $500,000 of such proceeds (the “Re-Loan”) to the Issuer in exchange for a senior secured convertible note in the aggregate principal amount of $500,000 (the “Re-Loan Note”) with a conversion price of $0.09 per share (subject to adjustment as set forth therein). Pursuant to the Security Documents, the Re-Loan Note is secured by a first priority lien on all current and future assets of the Issuer. The maturity date of the Re-Loan Note is the earlier of (i) June 7, 2013 and (ii) such earlier date as the unpaid principal balance of the Re-Loan Note becomes due and payable pursuant to the terms of the Re-Loan Note.

Immediately following the Re-Loan, an aggregate of $36,103,888.33 remained outstanding under the Reissued Notes, consisting of (i) $12,678,474.42 of principal outstanding under the Reissued Delaware Fund Note, (ii) $11,200,846.30 of principal outstanding under the Reissued Cayman Fund Note, (iii) $5,577,045.76 of principal outstanding under the Reissued VPC Onshore Fund Note and (iv) $6,647,521.85 of principal outstanding under the Reissued VPC Offshore Fund Note.

The remaining $500,000 of the proceeds will be re-loaned to the Issuer following the execution and delivery of an agreement among the Issuer, the Agent, the Jaynjean Levy Family Limited Partnership and Jean Levy (collectively, the “Levys”) regarding certain indebtedness of the Issuer held by the Levys, which agreement shall be in form and substance acceptable to the Agent in its sole discretion. The obligation of the Funds to reloan such proceeds to the Issuer is conditioned upon the absence of any event of default under the Amended and Restated Financing Agreement (other than those events of default forebeared upon pursuant to the First Amendment and those Events of Default in existence on May 10, 2013 for which the Issuer has provided notice to the Agent or for which the Agent otherwise had actual knowledge).

On May 22, 2012, the Agent notified the Issuer that certain events of default had occurred and are continuing under the Amended and Restated Financing Agreement. As a result of such events of default occurring and continuing, the Agent, pursuant to the terms of the Amended and Restated Financing Agreement, the Security Documents and Section 5/9-610 of the Illinois Uniform Commercial Code, for the benefit of the Funds, will sell all of the personal property and assets pledged as collateral under the Amended and Restated Financing Agreement (the “Second Article 9 Transaction”). Such assets will be sold pursuant to public auction to be held at the offices of Katten Muchin Rosenman LLP, 525 West Monroe Street, Chicago, Illinois 60661 on June 4, 2013 at 11:00 a.m. Central time.

Item 3. Source and Amount of Funds or Other Consideration

Item 3 is hereby amended to replace the first sentence thereof with the following:

As of the date hereof, (a) the Delaware Fund is the direct beneficial owner of 4,856,750 shares of Common Stock and 44,451,198 shares of Common Stock issuable to the Delaware Fund upon conversion of the Reissued Delaware Fund Note prior to the filing of the Charter Amendment (as defined below), (b) the Cayman Fund is the direct beneficial owner of 4,290,714 shares of Common Stock and 39,270,580 shares of Common Stock issuable to the Cayman Fund upon conversion of the Reissued Cayman Fund Note prior to the filing of the Charter Amendment, (c) the VPC Onshore Fund is the direct beneficial owner of 47,671,920 shares of Common Stock issuable to the VPC Onshore Fund upon conversion of the Reissued VPC Onshore Fund Note, the First Amendment VPC Onshore Fund Note, the Second Amendment Note and the Re-Loan Note, in each case prior to the filing of the Charter Amendment, (d) the VPC Offshore Fund is the direct beneficial owner of 23,306,456 shares of Common Stock issuable to the VPC Offshore Fund upon conversion of the Reissued VPC Offshore Fund Note prior to the filing of the Charter Amendment, and (e) Mr. Levy is the direct beneficial owner of an aggregate of 225,000 shares of Common Stock (the “Option Shares”) issuable to Mr. Levy upon exercise of the Options. The Shares set forth in the foregoing sentence, as set forth on the cover pages hereto, are referred to collectively in this Schedule 13D as the “Subject Shares.” As of the date of the Second Amendment (as defined below), the Issuer lacked sufficient authorized shares of Common Stock to deliver all of the shares of Common Stock issuable to the holders of the Convertible Notes (as defined below) upon conversion of the Convertible Notes (the “Conversion Shares”). Pursuant to the terms and subject to the conditions set forth in the First Amendment, the Issuer is required to seek stockholder approval to amend its certificate of incorporation to increase the number of authorized shares to at least 650,000,000 shares (the “Charter Amendment”), and, pursuant to the terms of each of the Existing Convertible Notes, prior to the filing of the Charter Amendment, the Issuer is not obligated to, nor shall, issue any shares of Common Stock upon conversion of such Existing Convertible Note in excess of the number of shares of Common Stock that is required to be reserved for conversions of the Existing Convertible Notes and allocated to the holder of such Convertible Note in accordance with the Amended and Restated Financing Agreement, as amended by the First Amendment and the Second Amendment (less any shares of Common Stock previously issued to such holder upon conversions of the Convertible Notes). The numbers of shares set forth above issuable to the Funds upon conversion of the Convertible Notes reflects such restriction. Pursuant to the terms of the Second Amendment, the Issuer is required to reserve and keep available, solely for any conversions of the Second Amendment Note, the number of shares of Common Stock issuable upon conversion of the Second Amendment Note. If the Charter Amendment had been filed as of the date hereof, (w) an aggregate of 84,861,255 shares of Common Stock would be issuable to the Delaware Fund as of the date hereof upon conversion of the Reissued Delaware Fund Note, (x) an aggregate of 74,970,998 shares of Common Stock would be issuable to the Cayman Fund as of the date hereof upon conversion of the Reissued Cayman Fund Note, (y) an aggregate of 140,730,137 shares of Common Stock would be issuable to the VPC Onshore Fund as of the date hereof upon conversion of the Reissued VPC Onshore Fund Note, the First Amendment VPC Onshore Fund Note, the Second Amendment Note and the Re-Loan Note, and (z) an aggregate of 44,494,080 shares of Common Stock would be issuable to the VPC Offshore Fund as of the date hereof upon conversion of the Reissued VPC Offshore Fund Note.

Item 3 is also hereby amended to add the following:

On May 14, 2013, the Issuer used the proceeds from the sale of its interest in Nu-Co Development GmbH to prepay an aggregate of $1,000,000 outstanding under the Existing Notes. Immediately following the prepayment, VPC Onshore Fund re-loaned $500,000 of such proceeds to the Issuer in exchange for a senior secured convertible note in the aggregate principal amount of $500,000 with a conversion price of $0.09 per share (subject to adjustment as set forth therein). Pursuant to the Security Documents, the Re-Loan Note is secured by a first priority lien on all current and future assets of the Issuer. The maturity date of the Re-Loan Note is the earlier of (i) June 7, 2013 and (ii) such earlier date as the unpaid principal balance of the Re-Loan Note becomes due and payable pursuant to the terms of the Re-Loan Note.

The remaining $500,000 of the proceeds will be re-loaned to the Issuer following the execution and delivery of an agreement among the Issuer, the Agent and the Levys regarding certain indebtedness of the Issuer held by the Levys, which agreement shall be in form and substance acceptable to the Agent in its sole discretion. The obligation of the Funds to reloan such proceeds to the Issuer is conditioned upon the absence of any event of default under the Amended and Restated Financing Agreement (other than those events of default forebeared upon pursuant to the First Amendment and those Events of Default in existence on May 10, 2013 for which the Issuer has provided notice to the Agent or for which the Agent otherwise had actual knowledge).

On May 22, 2012, the Agent notified the Issuer that certain events of default had occurred and are continuing under the Amended and Restated Financing Agreement. As a result of such events of default occurring and continuing, the Agent, pursuant to the terms of the Amended and Restated Financing Agreement, the Security Documents and Section 5/9-610 of the Illinois Uniform Commercial Code, for the benefit of the Funds, will sell all of the personal property and assets pledged as collateral under the Amended and Restated Financing Agreement.

Item 4. Purpose of Transaction

Item 4 is hereby amended to add the following:

The information set forth in Item 6 is incorporated herein by reference.

The transactions contemplated by the Second Article 9 Transaction will result in certain actions specified in Items 4(a) through (j) of Schedule 13D, including an extraordinary corporate transaction involving the Issuer, a transfer of a material amount of the assets of the Issuer, a material change in the present capitalization of the Issuer and a change in the Issuer’s charter, and may result in the acquisition of additional shares of Common Stock by the Reporting Persons. The Reporting Persons may review the Issuer’s operating, management, business affairs, capital needs and general industry and economic conditions, and, based on such review, the Reporting Persons may, from time to time, determine to increase or decrease their respective ownership of Common Stock, vote to approve an extraordinary corporate transaction with regard to the Issuer or engage in any of the events set forth in Items 4(a) through (j) of Schedule 13D. In addition, the Agent and the Funds reserve the right to pursue and exercise any or all remedies available to them under the Amended and Restated Financing Agreement, the Security Documents or applicable law as the senior creditors of the Issuer and in respect of the assets of the Issuer. Except as otherwise provided herein, the Reporting Persons currently have no intention of engaging in any of the events set forth in Items 4(a) through (j) of Schedule 13D.

Item 5. Interest in Securities of the Issuer

Item 5 is hereby amended and restated as follows:

(a), (b) According to the Issuer’s Annual Report on Form 10-Q for the fiscal quarter ended March 31, 2013, as filed with the Securities and Exchange Commission on May 14, 2013, 95,978,952 shares of the Common Stock of the Issuer were outstanding as of April 30, 2013. Based on the foregoing, the Subject Shares, in the aggregate, represented approximately 65.4% of the Common Stock of the Issuer outstanding as of such date, calculated by dividing (i) all of the Subject Shares by (ii) the sum of (A) 95,978,952 shares of the Common Stock of the Issuer outstanding as of April 30, 2013, as set forth in the Issuer’s Annual Report on Form 10-Q for the fiscal quarter ended March 31, 2013, (B) an aggregate of 154,700,154 shares of the Common Stock of the Issuer issuable upon conversion of the outstanding Convertible Notes prior to the filing of the Charter Amendment and (C) 225,000 Option Shares. For each Reporting Person, the percentage of the outstanding Common Stock of the Issuer represented by the shares of Common Stock of the Issuer beneficially owned by such Reporting Person is calculated by dividing (x) the number of Subject Shares directly or indirectly beneficially owned by such Reporting Person by (y) the sum of (I) the number of shares of Common Stock of the Issuer outstanding as set forth in the immediately preceding sentence and (II) the number of shares of Common Stock of the Issuer issuable upon conversion of the outstanding Convertible Notes prior to the filing of the Charter Amendment and/or exercise of the Options directly or indirectly beneficially owned by such Reporting Person.

The Convertible Notes provide for interest to be paid in kind at the Current Rate. In addition, since there is a continuing event of default under the Amended and Restated Financing Agreement, the Convertible Notes currently bear interest at a rate equal to the Current Rate plus 3%. Accordingly, the number of shares of Common Stock into which the Convertible Notes are convertible may increase and, accordingly, the shares of Common Stock beneficially owned by each of the Reporting Persons in respect of the Convertible Notes may increase over time (subject to the filing of the Charter Amendment, as described herein).

As of the date hereof, (a) the Delaware Fund is the direct beneficial owner of 4,856,750 shares of Common Stock and 44,451,198 shares of Common Stock issuable to the Delaware Fund upon conversion of the Reissued Delaware Fund Note prior to the filing of the Charter Amendment, (b) the Cayman Fund is the direct beneficial owner of 4,290,714 shares of Common Stock and 39,270,580 shares of Common Stock issuable to the Cayman Fund upon conversion of the Reissued Cayman Fund Note prior to the filing of the Charter Amendment, (c) the VPC Onshore Fund is the direct beneficial owner of 47,671,920 shares of Common Stock issuable to the VPC Onshore Fund upon conversion of the Reissued VPC Onshore Fund Note, the First Amendment VPC Onshore Fund Note, the Second Amendment Note and the Re-Loan Note, in each case prior to the filing of the Charter Amendment, (d) the VPC Offshore Fund is the direct beneficial owner of 23,306,456 shares of Common Stock issuable to the VPC Offshore Fund upon conversion of the Reissued VPC Offshore Fund Note prior to the filing of the Charter Amendment, and (e) Mr. Levy is the direct beneficial owner of 225,000 shares of Common Stock issuable to Mr. Levy upon exercise of the Options. GP I, as the general partner of each of the Delaware Fund and the Cayman Fund, may each be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Subject Shares beneficially owned directly by the Delaware Fund and the Subject Shares beneficially owned directly by the Cayman Fund as of the date hereof. GP II, as the general partner of each of the VPC Onshore Fund and the VPC Offshore Fund, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Subject Shares beneficially owned directly by the VPC Onshore Fund and the Subject Shares beneficially owned directly by the VPC Offshore Fund as of the date hereof. As the investment manager of each of the Funds, Capital Advisors may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) all of the Subject Shares (excluding the Option Shares). As the sole manager of each of GP I and GP II, RNL VPC may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) all of the Subject Shares (excluding the Option Shares). As the sole manager of Capital Advisors, Jacob Capital may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) all of the Subject Shares (excluding the Option Shares). By virtue of Richard Levy’s positions as sole member of Jacob Capital and the sole manager of RNL VPC, Mr. Levy may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) all of the Subject Shares (excluding the Option Shares).

See Item 3 above for a discussion of additional shares of Common Stock issuable to the Funds upon conversion of the Convertible Notes following the filing of the Charter Amendment.

Richard Levy intends to enter into agreements with one or more of the Funds whereby Mr. Levy will hold the Options for the economic benefit of one or more of the Funds.

(c) Except for the transactions described in Item 6, none of the Reporting Persons has effected any transaction in the Common Stock during the past 60 days.

(d) No other person is known to the Reporting Persons to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Subject Shares covered by this Schedule 13D.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Item 6 is hereby amended to add the following:

On May 14, 2013, the Issuer used the proceeds from the sale of its interest in Nu-Co Development GmbH to prepay an aggregate of $1,000,000 outstanding under the Existing Notes. Immediately following the prepayment, VPC Onshore Fund re-loaned $500,000 of such proceeds to the Issuer in exchange for the Re-Loan Note. Pursuant to the Security Documents, the Re-Loan Note is secured by a first priority lien on all current and future assets of the Issuer. The maturity date of the Re-Loan Note is the earlier of (i) June 7, 2013 and (ii) such earlier date as the unpaid principal balance of the Re-Loan Note becomes due and payable pursuant to the terms of the Re-Loan Note.

The remaining $500,000 of the proceeds will be re-loaned to the Issuer following the execution and delivery of an agreement among the Issuer, the Agent and the Levys regarding certain indebtedness of the Issuer held by the Levys, which agreement shall be in form and substance acceptable to the Agent in its sole discretion. The obligation of the Funds to reloan such proceeds to the Issuer is conditioned upon the absence of any Event of Default (other than those Events of Default forebeared upon pursuant to the First Amendment and those Events of Default in existence on May 10, 2013 for which the Issuer has provided notice to the Agent or for which the Agent otherwise had actual knowledge).
