                                the foregoing, nothing herein shall be deemed to
                                constitute an assignment of any
                                asset which, in the event of an assignment, becomes
                                void by operation of
                                applicable law or the assignment of which is otherwise
                                prohibited by applicable
                                law (in each case to the extent that such applicable
                                law is not overridden by

                                other similar applicable law);
                                provided, however, that to the extent permitted by

                                extent permitted by applicable law, this Agreement
                                shall create a valid security
                                interest in the proceeds of such asset.

                                limiting the generality of the foregoing, the term
“Obligations” shall include,
                                without limitation: (i) principal of, and interest
                                on the Debentures and the

                                payable but for the fact that the obligations to
                                pay such amounts are
                                unenforceable or not allowable due to the existence
                                of a bankruptcy,
                                reorganization or similar proceeding involving any

                                 "Organizational Documents"means with respect to any Debtor, the
                                documents by which such Debtor was organized (such
                                as a certificate of

                                governance of such Debtor (such as bylaws, a partnership
                                agreement or an
                                operating, limited liability or members agreement)

                                 "UCC" means the Uniform Commercial Code of the

                                which has jurisdiction
                                with respect to all, or any portion of, the Collateral
                                or this Agreement, from
                                time to time. It is the intent of the parties that
                                defined terms in the UCC
                                should be construed in their broadest sense so that
                                the term “Collateral” will
                                be construed in its broadest sense. Accordingly if
                                there are, from time to time,
                                changes to defined terms in the UCC that broaden
                                the definitions, they are
                                incorporated herein and if existing definitions in
                                the UCC are broader than the
                                amended definitions, the existing ones shall be controlling.

                                payment, performance and
                                discharge in full, as the case may be, of all of
                                the Obligations, each Debtor
                                hereby unconditionally and irrevocably pledges, grants
                                and hypothecates to the
                                Secured Parties a continuing security interest in
                                and to, a lien upon and a
                                right of set-off against all of their respective
                                right, title and interest of

                                  execution of this Agreement, each Debtor shall
                                  deliver or cause to be delivered

                                that payments received
                                by any Debtor after an Event of Default occurs and

                                the Agent and, if received by such Debtor, shall
                                be held in trust for and
                                immediately paid over to the Agent unless otherwise

                                unless prohibited by applicable law which cannot
                                be waived, purchase all or any
                                part of the Collateral being sold, free from and
                                discharged of all trusts,
                                claims, right of redemption and equities of any Debtor,
                                which are hereby waived

                                (iv) The
                                Secured Parties shall have the right (but not the
                                obligation) to notify any
                                account debtors and any obligors under instruments
                                or accounts to make payments
                                directly to the Secured Parties and to enforce the
                                Debtors’ rights against such
                                account debtors and obligors.
                              (v) The
                                Secured Parties may (but are not obligated to) direct
                                any financial intermediary
                                or any other person or entity holding any investment
                                property to transfer the
                                same to the Secured Parties or their designee.
                              (vi) The
                                Secured Parties may (but are not obligated to) transfer
                                any or all Intellectual
                                Property registered in the name of any Debtor at
                                the United States Patent and
                                Trademark Office and/or Copyright Office into the
                                name of the Secured Parties or
                                any designee or any purchaser of any Collateral.
                              (b) The
                                Agent
                                may comply with any applicable law in connection
                                with a disposition of
                                Collateral and such compliance will not be considered
                                adversely to affect the
                                commercial reasonableness of any sale of the Collateral.
                                The Agent may sell the
                                Collateral without giving any warranties and may
                                specifically disclaim such
                                warranties. If the Agent sells any of the Collateral
                                on credit, the Debtors will
                                only be credited with payments actually made by the
                                purchaser. In addition, each
                                Debtor waives any and all rights that it may have
                                to a judicial hearing in
                                advance of the enforcement of any of the Agent’s rights and remedies hereunder,
                                including, without limitation, its right following
                                an Event of Default to take
                                immediate possession of the Collateral and to exercise
                                its rights and remedies
                                with respect thereto.
                              (c) For
                                the
                                purpose of enabling the Agent to further exercise
                                rights and remedies under this
                                Section 8 or elsewhere provided by agreement or applicable
                                law, each Debtor
                                hereby grants to the Agent, for the benefit of the
                                Agent and the Secured
                                Parties, an irrevocable, nonexclusive license (exercisable
                                without payment of
                                royalty or other compensation to such Debtor) to
                                use, license or sublicense
                                following an Event of Default, any Intellectual Property
                                now owned or hereafter
                                acquired by such Debtor, and wherever the same may
                                be located, and including in
                                such license access to all media in which any of
                                the licensed items may be
                                recorded or stored and to all computer software and
                                programs used for the
                                compilation or printout thereof.
                              9.  Applications
                                of Proceeds.
                                The
                                proceeds of any such sale, lease or other disposition
                                of the Collateral
                                hereunder shall be applied first, to the expenses
                                of retaking, holding, storing,
                                processing and preparing for sale, selling, and the
                                like (including, without
                                limitation, any taxes, fees and other costs incurred
                                in connection therewith) of
                                the Collateral, to the reasonable attorneys’ fees and expenses incurred by the
                                Secured Parties in enforcing their rights hereunder
                                and in connection with
                                collecting, storing and 
17
                                disposing
                                of the Collateral, and then to satisfaction of the
                                Obligations pro rata among
                                the Secured Parties (based on then-outstanding principal
                                amounts of Debentures
                                at the time of any such determination), and to the
                                payment of any other amounts
                                required by applicable law, after which the Secured
                                Parties shall pay to the
                                applicable Debtor any surplus proceeds. If, upon
                                the sale, license or other
                                disposition of the Collateral, the proceeds thereof
                                are insufficient to pay all
                                amounts to which the Secured Parties are legally
                                entitled, the Debtors will be
                                liable for the deficiency, together with interest
                                thereon, at the rate of 10%
                                per annum or the lesser amount permitted by applicable
                                law (the “Default Rate”),
                                and the reasonable fees of any attorneys employed
                                by the Secured Parties to
                                collect such deficiency. To the extent permitted
                                by applicable law, each Debtor
                                waives all claims, damages and demands against the
                                Secured Parties arising out
                                of the repossession, removal, retention or sale of
                                the Collateral, unless due
                                solely to the gross negligence or willful misconduct
                                of the Secured Parties as
                                determined by a final judgment (not subject to further
                                appeal) of a court of
                                competent jurisdiction.
                              10. Securities
                                Law Provision.
                                Each
                                Debtor recognizes that Agent may be limited in its
                                ability to effect a sale to
                                the public of all or part of the Pledged Securities
                                by reason of certain
                                prohibitions in the Securities Act of 1933, as amended,
                                or other federal or
                                state securities laws (collectively, the “Securities
                                Laws”),
                                and
                                may be compelled to resort to one or more sales to
                                a restricted group of
                                purchasers who may be required to agree to acquire
                                the Pledged Securities for
                                their own account, for investment and not with a
                                view to the distribution or
                                resale thereof. Each Debtor agrees that sales so
                                made may be at prices and on
                                terms less favorable than if the Pledged Securities
                                were sold to the public, and
                                that Agent has no obligation to delay the sale of
                                any Pledged Securities for the
                                period of time necessary to register the Pledged
                                Securities for sale to the
                                public under the Securities Laws. Each Debtor shall
                                cooperate with Agent in its
                                attempt to satisfy any requirements under the Securities
                                Laws (including,
                                without limitation, registration thereunder if requested
                                by Agent) applicable to
                                the sale of the Pledged Securities by Agent.
                              11.  Costs
                                and Expenses.
                                Each
                                Debtor agrees to pay all reasonable out-of-pocket
                                fees, costs and expenses
                                incurred in connection with any filing required hereunder,
                                including without
                                limitation, any financing statements pursuant to
                                the UCC, continuation
                                statements, partial releases and/or termination statements
                                related thereto or
                                any expenses of any searches reasonably required
                                by the Secured Parties. The
                                Debtors shall also pay all other claims and charges
                                which in the reasonable
                                opinion of the Secured Parties might prejudice, imperil
                                or otherwise affect the
                                Collateral or the Security Interest therein. The
                                Debtors will also, upon demand,
                                pay to the Secured Parties the amount of any and
                                all reasonable expenses,
                                including the reasonable fees and expenses of its
                                counsel and of any experts and
                                agents, which the Secured Parties may incur in connection
                                with (i) the
                                enforcement of this Agreement, (ii) the custody or
                                preservation of, or the sale
                                of, collection from, or other realization upon, any
                                of the Collateral, or (iii)
                                the exercise or enforcement of any of the rights
                                of the Secured Parties under
                                the Debentures. Until so paid, any fees payable hereunder
                                shall be added to the
                                principal amount of the Debentures and shall bear
                                interest at the Default
                                Rate.

                                12.  Responsibility
                                for Collateral.
                                The
                                Debtors assume all liabilities and responsibility
                                in connection with all
                                Collateral, and the Obligations shall in no way be
                                affected or diminished by
                                reason of the loss, destruction, damage or theft
                                of any of the Collateral or its
                                unavailability for any reason. Without limiting the
                                generality of the foregoing,
                                (a) neither the Agent nor any Secured Party (i) has

                                deemed by final order of a court of competent jurisdiction

                                other than the Secured Parties, then, in any such
                                event, each Debtor’s

                                assets, or to pursue any other remedy. Each Debtor
                                waives any defense arising by
                                reason of the application of the statute of limitations
                                to any obligation
                                secured hereby.

                                forth in this Agreement, no provision of this Agreement

                                the
                                event any provision of this Agreement is held to
                                be invalid, prohibited or
                                unenforceable in any jurisdiction for any reason,
                                unless such provision is
                                narrowed by judicial construction, this Agreement
                                shall, as to such
                                jurisdiction, be construed as if such invalid, prohibited
                                or unenforceable
                                provision had been more narrowly drawn so as not
                                to be invalid, prohibited or
                                unenforceable. If, notwithstanding the foregoing,
                                any provision of this

                                in any
                                jurisdiction, such provision, as to such jurisdiction,
                                shall be ineffective to
                                the extent of such invalidity, prohibition or unenforceability
                                without
                                invalidating the remaining portion of such provision
                                or the other provisions of
                                this Agreement and without affecting the validity
                                or enforceability of such
                                provision or the other provisions of this Agreement
                                in any other
                                jurisdiction.
                              (e)
                                 No
                                waiver
                                of any breach or default or any right under this
                                Agreement shall be considered
                                valid unless in writing and signed by the party giving
                                such waiver, and no such
                                waiver shall be deemed a waiver of any subsequent
                                breach or default or right,
                                whether of the same or similar nature or otherwise.

                                and its successors and assigns.

                                and deliver such further
                                documents as may be necessary or appropriate in order
                                to carry out the
                                provisions and purposes of this Agreement.

                                sufficient service of process and notice thereof.
                                Nothing contained herein shall
                                be deemed to limit in any way any right to serve

                                provisions of this Agreement, then the prevailing
                                party in such proceeding shall
                                be reimbursed by the other party for its reasonable

                                executed shall be deemed to be an original and, all

                                delivered by facsimile transmission, such signature
                                shall create a valid binding
                                obligation of the party executing (or on whose behalf
                                such signature is

                                as if such facsimile signature

                                the obligations of each Debtor
                                to the Secured Parties hereunder.
                              (k) Each
                                Debtor shall indemnify, reimburse and hold harmless

                                competent jurisdiction. This
                                indemnification provision is in addition to, and
                                not in limitation of, any other
                                indemnification provision in the Debentures, the

                                its right to be substituted
                                for such Debtor as a partner or member, as applicable,
