                  6. RIGHTS AND REMEDIES UPON DEFAULT. Upon the occurrence of any Event of Default and while such Event of Default is continuing:

Upon the written consent of the Secured Party, the Secured Party may exercise in addition to all other rights and remedies granted to it under this Security Agreement and the Purchase Agreement all rights and remedies of a Secured Party under the UCC. Without limiting the generality of the foregoing, each Grantor expressly agrees that in any such event the Secured Party, without demand of performance or other demand, advertisement or notice of any kind (except the notice specified below of time and place of public or private sale) to or upon either Grantor or any other person, may (i) reclaim, take possession, recover, store, maintain, finish, repair, prepare for sale or lease, shop, advertise for sale or lease and sell or lease (in the manner provided herein) the Collateral, and in connection with the liquidation of the Collateral and collection of the accounts receivable pledged as Collateral, use any Trademark, Copyright, or process used or owned by either Grantor and (ii) forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and may forthwith sell, lease, assign, give an option or options to purchase or sell or otherwise dispose of and deliver said Collateral (or contract to do so), or any part thereof, in one or more parcels at public or private sale or sales, at any exchange or broker's board or at the Secured Party's offices or elsewhere at such prices as it may deem commercially reasonable, for cash or on credit or for future delivery without assumption of any credit risk.

Each Grantor agrees that the Secured Party need not give more than thirty (30) days' notice of the time and place of any public sale or of the time after which a private sale may take place and that such notice is reasonable notification of such matters.

      6.     As to any Collateral constituting certificated securities or uncertificated securities, if, at any time when Secured Party shall determine to exercise its right to sell the whole or any part of such
              Collateral hereunder, such Collateral or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under Securities Act of 1933, as amended (as so amended the
             "Act"), the Secured Party may, in their reasonable discretion (subject only to applicable requirements of law), sell such Collateral or part thereof by private sale in such manner and under such
              circumstances as the Secured Party may deem necessary or advisable, but subject to the other requirements of this Section 6(b), and shall not be required to effect such registration or cause the

                same to be effected. Without limiting the generality of the foregoing, in any such event the Secured Party may, in their discretion, (i) in accordance with applicable securities laws, proceed to
                make such private sale notwithstanding that a registration statement for the purpose of registering such Collateral or part thereof could be or shall have been filed under the Act; (ii) approach and
                negotiate with a single possible purchaser to effect such sale; and (iii) restrict such sale to a purchaser who will represent and agree that such purchaser is purchasing for its own account, for
                investment, and not with a view to the distribution or sale of such Collateral or part thereof. In addition to a private sale as provided above in this Section 6(b), if any of such Collateral shall not
                be freely distributable to the public without registration under the Act at the time of any proposed sale hereunder, then the Secured Party shall not be required to effect such registration or cause
                the same to be effected but may, in their discretion (subject only to applicable requirements of law), require that any sale hereunder (including a sale at auction) be conducted subject to such
                restrictions as the Secured Party may, in their discretion, deem necessary or appropriate in order that such sale (notwithstanding any failure so to register) may be effected in compliance with the
                Bankruptcy Code and other laws affecting the enforcement of creditors' rights and the Act and all applicable state securities laws.

Each Grantor also agrees to pay all fees, costs and expenses of the Secured Party, including, without limitation, reasonable attorneys' fees, incurred in connection with the enforcement of any of its rights and remedies hereunder.

Each Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Security Agreement or any Collateral.

FIRST , to the Secured Party in an amount sufficient to pay in full the reasonable costs of such the Secured Party in connection with such sale, disposition or other realization, including all fees, costs, expenses, liabilities and advances incurred or made by the Secured Party in connection therewith, including, without limitation, reasonable attorneys' fees;

SECOND , to the Secured Party of the then unpaid Secured Obligations of the Secured Party; and

FINALLY , upon payment in full of the Secured Obligations, to Platinum, PIP LP or their respective representatives, in accordance with the UCC or as a court of competent jurisdiction may direct.

              7. ACTIONS BY THE SECURED PARTY AND AMENDMENTS. All actions, omissions and decisions of the Secured Party hereunder or any amendment of this Security Agreement (each called herein an "Act of the Secured Party") shall be determined by and require the written consent of the Secured Party. The Secured Party shall take such actions and execute such documents as may be necessary to confirm or accomplish any Act of the Secured Party.

              8. INDEMNITY.
