      related thereto, (iv) all trade secrets arising under the laws of the
      United States, any other country or any political subdivision thereof, (v)

            (d) "Majority in Interest" shall mean, at any time of determination,
      the majority in interest (based on then-outstanding principal amounts of
      Debentures at the time of such determination) of the Secured Parties.

            (e) "Necessary Endorsement" shall mean undated stock powers endorsed
      in blank or other proper instruments of assignment duly executed and such
      other instruments or documents as the Agent (as that term is defined
      below) may reasonably request.

            (f) "Obligations" means all of the liabilities and obligations
      (primary, secondary, direct, contingent, sole, joint or several) due or to
      become due, or that are now or may be hereafter contracted or acquired, or
      owing to, of any Debtor to the Secured Parties, including, without
      limitation, all obligations under this Agreement, the November Notes, the
      Debentures, the Guaranty and any other instruments, agreements or other
      documents executed and/or delivered in connection herewith or therewith,
      in each case, whether now or hereafter existing, voluntary or involuntary,
      direct or indirect, absolute or contingent, liquidated or unliquidated,
      whether or not jointly owed with others, and whether or not from time to
      time decreased or extinguished and later increased, created or incurred,
      and all or any portion of such obligations or liabilities that are paid,
      to the extent all or any part of such payment is avoided or recovered
      directly or indirectly from any of the Secured Parties as a preference,
      fraudulent transfer or otherwise as such obligations may be amended,
      supplemented, converted, extended or modified from time to time. Without
      limiting the generality of the foregoing, the term "Obligations" shall
      include, without limitation: (i) principal of, and interest on the
      Debentures and the November Notes and the loans extended pursuant thereto;
      (ii) any and all other fees, indemnities, costs, obligations and
      liabilities of the Debtors from time to time under or in connection with

      in connection herewith or therewith; and (iii) all amounts (including but
      not limited to post-petition interest) in respect of the foregoing that
      would be 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 Debtor.


                                       4

            (g) "Organizational Documents" means with respect to any Debtor, the
      documents by which such Debtor was organized (such as a certificate of
      incorporation, certificate of limited partnership or articles of
      organization, and including, without limitation, any certificates of
      designation for preferred stock or other forms of preferred equity) and
      which relate to the internal governance of such Debtor (such as bylaws, a

            (h) "UCC" means the Uniform Commercial Code of the State of
      California and or any other applicable law of any state or states 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.

      2. Grant of Perfected First Priority Security Interest. As an inducement
for the Secured Parties to extend the loans as evidenced by the Debentures and
to secure the complete and timely 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 Agent, for the benefit
of the Secured Parties, a continuing and perfected security interest in and to,
a lien upon and a right of set-off against all of their respective right, title
and interest of whatsoever kind and nature in and to, the Collateral (the
"Security Interest").

      3. Delivery of Certain Collateral. Contemporaneously or prior to the
execution of this Agreement, each Debtor shall deliver or cause to be delivered
to the Agent (a) any and all certificates and other instruments representing or
evidencing the Pledged Securities, and (b) any and all certificates and other
instruments or documents representing any of the other Collateral, in each case,
together with all Necessary Endorsements. The Debtors are, contemporaneously
with the execution hereof, delivering to Agent, or have previously delivered to
Agent, a true and correct copy of each Organizational Document governing any of
the Pledged Securities.

      4. Representations, Warranties, Covenants and Agreements of the Debtors.
Except as set forth under the corresponding section of the disclosure schedules
delivered to the Agent concurrently herewith (the "Disclosure Schedules") which
Disclosure Schedules shall be deemed a part hereof, each Debtor represents and
warrants to, and covenants and agrees with, the Secured Parties as follows:

            (a) Each Debtor has the requisite corporate, partnership, limited
      liability company or other power and authority to enter into this
      Agreement and otherwise to carry out its obligations hereunder. The
      execution, delivery and performance by each Debtor of this Agreement and
      the filings contemplated therein have been duly authorized by all
      necessary action on the part of such Debtor and no further action is
      required by such Debtor. This Agreement has been duly executed by each
      Debtor. This Agreement constitutes the legal, valid and binding obligation
      of each Debtor, enforceable against each Debtor in accordance with its
      terms except as such enforceability may be limited by applicable
      bankruptcy, insolvency, reorganization and similar laws of general
      application relating to or affecting the rights and remedies of creditors
      and by general principles of equity.


                                       5

            (b) The Debtors have no place of business or offices where their
      respective books of account and records are kept (other than temporarily
      at the offices of its attorneys or accountants) or places where Collateral
      is stored or located, except as set forth on Schedule A attached hereto.
      Except as specifically set forth on Schedule A, each Debtor is the record
      owner of the real property where such Collateral is located, and there
      exist no mortgages or other liens on any such real property except for
      Permitted Liens (as defined in the Debentures). Except as disclosed on
      Schedule A, none of such Collateral is in the possession of any consignee,
      bailee, warehouseman, agent or processor.

            (c) Except for Permitted Liens (as defined in the Debentures) and
      except as set forth on Schedule B attached hereto, the Debtors are the
      sole owner of the Collateral (except for non-exclusive licenses granted by
      any Debtor in the ordinary course of business), free and clear of any
      liens, security interests, encumbrances, rights or claims, and are fully
      authorized to grant the Security Interest. Except as set forth on Schedule
      B, there is not on file in any governmental or regulatory authority,
      agency or recording office an effective financing statement, security
      agreement, license or transfer or any notice of any of the foregoing
      (other than those that will be filed in favor of the Agent, for the
      benefit of the Secured Parties pursuant to this Agreement) covering or
      affecting any of the Collateral. So long as this Agreement shall be in
      effect, the Debtors shall not execute and shall not knowingly permit to be
      on file in any such office or agency any other financing statement or
      other document or instrument (except to the extent filed or recorded in
      favor of the Agent, for the benefit of the Secured Parties pursuant to the
      terms of this Agreement).

            (d) No written claim has been received that any material portion of
      the Collateral or Debtor's use of any material portion of the Collateral
      violates the rights of any third party. There has been no adverse decision
      to any Debtor's claim of ownership rights in or exclusive rights to use
      any material portion of the Collateral in any jurisdiction or to any
      Debtor's right to keep and maintain such Collateral in full force and
      effect, and there is no proceeding involving said rights pending or, to
      the best knowledge of any Debtor, threatened before any court, judicial
      body, administrative or regulatory agency, arbitrator or other
      governmental authority.

            (e) Each Debtor shall at all times maintain its books of account and
      records relating to the Collateral at its principal place of business and
      its Collateral at the locations set forth on Schedule A attached hereto
      and may not relocate such books of account and records or tangible
      Collateral unless it delivers to the Agent at least 30 days prior to such
      relocation (i) written notice of such relocation and the new location
      thereof (which must be within the United States) and (ii) evidence that
      appropriate financing statements under the UCC and other necessary
      documents have been filed and recorded and other steps have been taken to
      perfect the Security Interest to create in favor of the Secured Parties,
      through the Agent, a valid, perfected and continuing perfected lien in the
      Collateral.


                                       6
<PAGE>

            (f) This Agreement creates in favor of the Agent, for the benefit of
      the Secured Parties a valid security interest in the Collateral, subject
      only to Permitted Liens (as defined in the Debentures) securing the
      payment and performance of the Obligations. Upon making the filings
      described in the immediately following paragraph, all security interests
      created hereunder in any Collateral which may be perfected by filing
      Uniform Commercial Code financing statements shall have been duly
      perfected. Except for the filing of the Uniform Commercial Code financing
      statements referred to in the immediately following paragraph, the
      recordation of the Intellectual Property Security Agreement (as defined
      below) with respect to copyrights and copyright applications in the United
      States Copyright Office referred to in paragraph (m), the execution and
      delivery of deposit account control agreements satisfying the requirements
      of Section 9-104(a)(2) of the UCC with respect to each deposit account of
      the Debtors, and the delivery of the certificates and other instruments
      provided in Section 3, no action is necessary to create, perfect or
      protect the security interests created hereunder. Without limiting the
      generality of the foregoing, except for the filing of said financing
      statements, the recordation of said Intellectual Property Security
      Agreement, and the execution and delivery of said deposit account control
      agreements, no consent of any third parties and no authorization, approval
      or other action by, and no notice to or filing with, any governmental
      authority or regulatory body is required for (i) the execution, delivery
      and performance of this Agreement, (ii) the creation or perfection of the
      Security Interests created hereunder in the Collateral or (iii) the
      enforcement of the rights of the Agent and the Secured Parties hereunder.

            (g) Each Debtor hereby authorizes the Agent to file one or more
      financing statements under the UCC, with respect to the Security Interest
      with the proper filing and recording agencies in any jurisdiction deemed
      proper by it.

            (h) The execution, delivery and performance of this Agreement by the
      Debtors does not (i) violate any of the provisions of any Organizational
      Documents of any Debtor or any judgment, decree, order or award of any
      court, governmental body or arbitrator or any applicable law, rule or
      regulation applicable to any Debtor or (ii) conflict with, or constitute a
      default (or an event that with notice or lapse of time or both would
      become a default) under, or give to others any rights of termination,
      amendment, acceleration or cancellation (with or without notice, lapse of
      time or both) of, any agreement, credit facility, debt or other instrument
      (evidencing any Debtor's debt or otherwise) or other understanding to
      which any Debtor is a party or by which any property or asset of any
      Debtor is bound or affected. No consent (including, without limitation,
      from stockholders or creditors of any Debtor) is required for any Debtor
      to enter into and perform its obligations hereunder.

            (i) The capital stock and other equity interests listed on Schedule
      H hereto (the "Pledged Securities") represent all of the capital stock and
      other equity interests of the Guarantors, and represent all capital stock
      and other equity interests owned, directly or indirectly, by the Company
      (other than the stock of the Immaterial Subsidiaries). All of the Pledged
      Securities are validly issued, fully paid and nonassessable, and the
      Company is the legal and beneficial owner of the Pledged Securities, free
      and clear of any lien, security interest or other encumbrance except for
      the security interests created by this Agreement and other Permitted Liens
      (as defined in the Debentures).


                                       7

            (j) The ownership and other equity interests in partnerships and
      limited liability companies (if any) included in the Collateral (the
      "Pledged Interests") by their express terms do not provide that they are
      securities governed by Article 8 of the UCC and are not held in a
      securities account or by any financial intermediary.

            (k) Except for Permitted Liens (as defined in the Debentures), each
      Debtor shall at all times maintain the liens and Security Interest
      provided for hereunder as valid and perfected first priority liens and
      security interests in the Collateral in favor of the Agent for the benefit
      of the Secured Parties until this Agreement and the Security Interest
      hereunder shall be terminated pursuant to Section 11 hereof. Each Debtor
      hereby agrees to use commercially reasonable efforts to defend the same
      against the claims of any and all persons and entities. Each Debtor shall
      safeguard and protect all Collateral for the account of the Secured
      Parties through the Agent. At the request of the Agent, each Debtor will
      sign and deliver to the Agent on behalf of the Secured Parties at any time
      or from time to time one or more financing statements pursuant to the UCC
      in form reasonably satisfactory to the Agent and will pay the cost of
      filing the same in all public offices wherever filing is, or is deemed by
      the Agent to be, necessary or desirable to effect the rights and
      obligations provided for herein. Without limiting the generality of the
      foregoing, each Debtor shall pay all fees, taxes and other amounts
      necessary to maintain the Collateral and the Security Interest hereunder,
      and each Debtor shall obtain and furnish to the Agent from time to time,
      upon demand, such releases and/or subordinations of claims and liens which
      may be required to maintain the priority of the Security Interest
      hereunder.

            (l) No Debtor will transfer, pledge, hypothecate, encumber, license,
      sell or otherwise dispose of any of the Collateral (except for
      non-exclusive licenses granted by a Debtor in its ordinary course of
      business and sales of inventory by a Debtor in its ordinary course of
      business) without the prior written consent of a Majority in Interest.

            (m) Each Debtor shall keep and preserve its equipment, inventory and
      other tangible Collateral in good condition, repair and order and shall
      not operate or locate any such Collateral (or cause to be operated or
      located) in any area excluded from insurance coverage.

            (n) Each Debtor shall maintain with financially sound and reputable
      insurers, insurance with respect to the Collateral against loss or damage
      of the kinds and in the amounts customarily insured against by entities of
      established reputation having similar properties similarly situated and in
      such amounts as are customarily carried under similar circumstances by
      other such entities and otherwise as is prudent for entities engaged in
      similar businesses but in any event sufficient to cover the full
      replacement cost thereof. Each Debtor shall cause each insurance policy
      issued in connection herewith to provide, and the insurer issuing such
      policy to certify to the Agent that (a) the Agent will be named as lender
      loss payee and additional insured under each such insurance policy; (b) if
      such insurance be proposed to be cancelled or materially changed for any
      reason whatsoever, such insurer will promptly notify the Agent and such
      cancellation or change shall not be effective as to the Agent for at least
      thirty (30) days after receipt by the Agent of such notice, unless the
      effect of such change is to extend or increase coverage under the policy;
      and (c) the Agent will have the right (but no obligation) at its election
      to remedy any default in the payment of premiums within thirty (30) days
      of notice from the insurer of such default. If no Event of Default (as
      defined in the Debentures) exists, loss payments in each instance will be
      applied by the applicable Debtor to the repair and/or replacement of
      property with respect to which the loss was incurred to the extent
      reasonably feasible, and any loss payments or the balance thereof
      remaining, to the extent not so applied, shall be payable to the
      applicable Debtor; provided, however, that payments received by any Debtor
      after an Event of Default occurs and is continuing shall be paid to the
      Agent on behalf of the Secured Parties and, if received by such Debtor,
      shall be held in trust for the Secured Parties and immediately paid over
      to the Agent unless otherwise directed in writing by the Agent. Copies of
      such policies or the related certificates, in each case, naming the Agent
      on behalf of the Secured Parties as lender loss payee and additional
      insured shall be delivered to the Agent upon its request and at the time
      any new policy of insurance is issued.

      interest hereunder, substantially in a form reasonably acceptable to the

      approvals that are required by any governmental or regulatory body in
      order to permit the sale of the Pledged Securities to the Transferee or

      Transferee or Agent to continue the business of the Debtors and their
      direct and indirect subsidiaries.

            (mm) Without limiting the generality of the other obligations of the
      Debtors hereunder, each Debtor shall promptly (i) cause to be registered
      at the United States Copyright Office all of its material copyrights and
      (ii) cause the security interest contemplated hereby with respect to all
      Intellectual Property registered at the United States Copyright Office or
      United States Patent and Trademark Office to be duly recorded at the
      applicable office.

            (nn) Each Debtor will from time to time, at the joint and several
      expense of the Debtors, promptly execute and deliver all such further
      instruments and documents, and take all such further action as may be
      necessary or desirable, or as the Agent may reasonably request, in order
      to perfect and protect any security interest granted or purported to be
      granted hereby or to enable the Secured Parties, through the Agent, to

      respect of such Collateral.

      5. Effect of Pledge on Certain Rights. If any of the Collateral subject to
this Agreement consists of nonvoting equity or ownership interests (regardless
of class, designation, preference or rights) that may be converted into voting
equity or ownership interests upon the occurrence of certain events (including,
without limitation, upon the transfer of all or any of the other stock or assets
of the issuer), it is agreed that the pledge of such equity or ownership
interests pursuant to this Agreement or the enforcement of any of Agent's rights
hereunder shall not be deemed to be the type of event which would trigger such
conversion rights notwithstanding any provisions in the Organizational Documents
or agreements to which any Debtor is subject or to which any Debtor is party.

            (a) Upon the occurrence of any Event of Default and at any time
      thereafter, each Debtor shall, upon receipt of any revenue, income,
      dividend, interest or other sums subject to the Security Interest, whether
      payable pursuant to the Debentures, the November Notes or otherwise, or of

      Pledged Securities or instruments representing Pledged Securities acquired
      after the date hereof, or any options, warrants, rights or other similar
      property or certificates representing a dividend, or any distribution in
      connection with any recapitalization, reclassification or increase or
      reduction of capital, or issued in connection with any reorganization of
      such Debtor or any of its direct or indirect subsidiaries) in respect of

      8. Rights and Remedies Upon Default.

            (a) Upon the occurrence of any Event of Default declared by holders
      of at least 30% aggregate principal amount of Debentures and at any time
      thereafter, the Secured Parties, acting through the Agent, shall have the
      right to exercise all of the remedies conferred hereunder and under the
      Debentures, and the Secured Parties shall have all the rights and remedies
      of a secured party under the UCC. Without limitation, the Agent, for the
      benefit of the Secured Parties, shall have the following rights and
      powers:

                  (i) The Agent shall have the right to take possession of the
            Collateral and, for that purpose, enter, with the aid and assistance
            of any person, any premises where the Collateral, or any part
            thereof, is or may be placed and remove the same, and each Debtor
            shall assemble the Collateral and make it available to the Agent at
            places which the Agent shall reasonably select, whether at such
            Debtor's premises or elsewhere, and make available to the Agent,
            without rent, all of such Debtor's respective premises and
            facilities for the purpose of the Agent taking possession of,
            removing or putting the Collateral in saleable or disposable form.

                  (ii) Upon notice to the Debtors by Agent, all rights of each
            Debtor to exercise the voting and other consensual rights which it
            would otherwise be entitled to exercise and all rights of each
            Debtor to receive the dividends and interest which it would
            otherwise be authorized to receive and retain, shall cease. Upon
            such notice, Agent shall have the right to receive, for the benefit
            of the Secured Parties any interest, cash dividends or other
            payments on the Collateral and, at the option of Agent, to exercise
            in such Agent's discretion all voting rights pertaining thereto.
            Without limiting the generality of the foregoing, Agent shall have
            the right (but not the obligation) to exercise all rights with
            respect to the Collateral as it were the sole and absolute owner
            thereof, including, without limitation, to vote and/or to exchange,
            at its sole discretion, any or all of the Collateral in connection
            with a merger, reorganization, consolidation, recapitalization or
            other readjustment concerning or involving the Collateral or any
            Debtor or any of its direct or indirect subsidiaries.

                  (iii) The Agent shall have the right to operate the business
            of each Debtor using the Collateral and shall have the right to
            assign, sell, lease or otherwise dispose of and deliver all or any
            part of the Collateral, at public or private sale or otherwise,
            either with or without special conditions or stipulations, for cash
            or on credit or for future delivery, in such parcel or parcels and
            at such time or times and at such place or places, and upon such
            terms and conditions as the Agent may deem commercially reasonable,
            all without (except as shall be required by applicable statute and
            cannot be waived) advertisement or demand upon or notice to any
            Debtor or right of redemption of a Debtor, which are hereby
            expressly waived. Upon each such sale, lease, assignment or other
            transfer of Collateral, the Agent, for the benefit of the Secured
            Parties, may, 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 and released.

                  (iv) The Agent 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 Agent, on behalf of the
            Secured Parties, and to enforce the Debtors' rights against such
            account debtors and obligors.

                  (v) The Agent, for the benefit of 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 Agent, on behalf of the Secured Parties, or their
            designee.

                  (vi) The Agent 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 shall 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.


                                       16

      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 Agent in enforcing the Secured
Parties' rights hereunder and in connection with collecting, storing and
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 and November Notes 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 provide
reasonable cooperation with Agent in its attempt to satisfy any requirements
under the Securities Laws 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 Agent. The Debtors shall also pay all other claims
and charges which in the reasonable opinion of the Agent is reasonably likely to
prejudice, imperil or otherwise affect any material portion of the Collateral or
the Security Interest therein. The Debtors will also, upon demand, pay to the
Agent 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 Agent,
for the benefit of 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 or November Notes. Until so paid, any fees payable hereunder
shall be added to the principal amount of the Debentures or November Notes and
shall bear interest at the Default Rate.


                                       17
<PAGE>

      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 any duty (either before or after an Event of Default) to collect
any amounts in respect of the Collateral or to preserve any rights relating to
the Collateral, or (ii) has any obligation to clean-up or otherwise prepare the
Collateral for sale, and (b) each Debtor shall remain obligated and liable under
each contract or agreement included in the Collateral to be observed or
performed by such Debtor thereunder. Neither the Agent nor any Secured Party
shall have any obligation or liability under any such contract or agreement by
reason of or arising out of this Agreement or the receipt by the Agent or any
Secured Party of any payment relating to any of the Collateral, nor shall the
Agent or any Secured Party be obligated in any manner to perform any of the
obligations of any Debtor under or pursuant to any such contract or agreement,
to make inquiry as to the nature or sufficiency of any payment received by the
Agent or any Secured Party in respect of the Collateral or as to the sufficiency
of any performance by any party under any such contract or agreement, to present
or file any claim, to take any action to enforce any performance or to collect
the payment of any amounts which may have been assigned to the Agent or to which
the Agent or any Secured Party may be entitled at any time or times.

      13. [RESERVED].

      14. Term of Agreement. This Agreement and the Security Interest shall
terminate on the date on which all payments under the Debentures and November
Notes have been indefeasibly paid in full and all other Obligations have been
paid or discharged; provided, however, that all indemnities of the Debtors
contained in this Agreement (including, without limitation, Annex B hereto)
shall survive and remain operative and in full force and effect regardless of
the termination of this Agreement.

      15. Power of Attorney; Further Assurances.

            (a) Each Debtor authorizes the Agent, and does hereby make,
      constitute and appoint the Agent and its respective officers, agents,
      successors or assigns with full power of substitution, as such Debtor's
      true and lawful attorney-in-fact, with power, in the name of the Agent or
      such Debtor, to, after the occurrence and during the continuance of an
      Event of Default, (i) endorse any note, checks, drafts, money orders or
      other instruments of payment (including payments payable under or in
      respect of any policy of insurance) in respect of the Collateral that may
      come into possession of the Agent; (ii) to sign and endorse any financing
      statement pursuant to the UCC or any invoice, freight or express bill,
      bill of lading, storage or warehouse receipts, drafts against debtors,
      assignments, verifications and notices in connection with accounts, and
      other documents relating to the Collateral; (iii) to pay or discharge
      taxes, liens, security interests or other encumbrances at any time levied
      or placed on or threatened against the Collateral; (iv) to demand,
      collect, receipt for, compromise, settle and sue for monies due in respect
      of the Collateral; (v) to transfer any Intellectual Property or provide
      licenses respecting any Intellectual Property; and (vi) generally, at the
      option of the Agent, and at the expense of the Debtors, at any time, or
      from time to time, to execute and deliver any and all documents and
      instruments and to do all acts and things which the Agent deem necessary
      to protect, preserve and realize upon the Collateral and the Security
      Interest granted therein in order to effect the intent of this Agreement
      and the Debentures and November Notes all as fully and effectually as the
      Debtors might or could do; and each Debtor hereby ratifies all that said
      attorney shall lawfully do or cause to be done by virtue hereof. This
      power of attorney is coupled with an interest and shall be irrevocable for
      the term of this Agreement and thereafter as long as any of the
      Obligations shall be outstanding. The designation set forth herein shall
      be deemed to amend and supersede any inconsistent provision in the
      Organizational Documents or other documents or agreements to which any
      Debtor is subject or to which any Debtor is a party. Without limiting the
      generality of the foregoing, after the occurrence and during the
      continuance of an Event of Default, each Secured Party is specifically
      authorized to execute and file any applications for or instruments of
      transfer and assignment of any patents, trademarks, copyrights or other
      Intellectual Property with the United States Patent and Trademark Office
      and the United States Copyright Office.


                                       18
<PAGE>

            (b) On a continuing basis, each Debtor will make, execute,
      acknowledge, deliver, file and record, as the case may be, with the proper
      filing and recording agencies in any jurisdiction, including, without
      limitation, the jurisdictions indicated on Schedule C attached hereto, all
      such instruments, and take all such action as may reasonably be deemed
      necessary or advisable, or as reasonably requested by the Agent, to
      perfect the Security Interest granted hereunder and otherwise to carry out
      the intent and purposes of this Agreement, or for assuring and confirming
      to the Agent the grant or perfection of a perfected security interest in
      all the Collateral under the UCC.

            (c) Each Debtor hereby irrevocably appoints the Agent as such
      Debtor's attorney-in-fact, with full authority in the place and instead of
      such Debtor and in the name of such Debtor, from time to time in the
      Agent's discretion, to take any action and to execute any instrument which
      the Agent may deem necessary or advisable to accomplish the purposes of
      this Agreement, including the filing, in its sole discretion, of one or
      more financing or continuation statements and amendments thereto, relative
      to any of the Collateral without the signature of such Debtor where
      permitted by law, which financing statements may (but need not) describe
      the Collateral as "all assets" or "all personal property" or words of like
      import, and ratifies all such actions taken by the Agent. This power of
      attorney is coupled with an interest and shall be irrevocable for the term
      of this Agreement and thereafter as long as any of the Obligations shall
      be outstanding.

      16. Notices. All notices, requests, demands and other communications
hereunder shall be subject to the notice provision of the Purchase Agreement (as
such term is defined in the Debentures).


                                       19
<PAGE>

      17. Other Security. To the extent that the Obligations are now or
hereafter secured by property other than the Collateral or by the guarantee,
endorsement or property of any other person, firm, corporation or other entity,
then the Agent shall have the right, in its sole discretion, to pursue,
relinquish, subordinate, modify or take any other action with respect thereto,
without in any way modifying or affecting any of the Secured Parties' rights and
remedies hereunder.

      18. Appointment of Agent. The Secured Parties hereby appoint Midsummer
Investment Ltd. to act as their agent ("Midsummer" or "Agent") for purposes of
exercising any and all rights and remedies of the Secured Parties hereunder.
Such appointment shall continue until revoked in writing by a Majority in
Interest, at which time a Majority in Interest shall appoint a new Agent;
provided, that Midsummer may not be removed as Agent unless Midsummer shall then
hold less than $50,000 principal amount of Debentures. The Agent shall have the
rights, responsibilities and immunities set forth in Annex B hereto.

      19. Miscellaneous.

            (a) No course of dealing between the Debtors and the Secured
      Parties, nor any failure to exercise, nor any delay in exercising, on the
      part of the Secured Parties, any right, power or privilege hereunder or
      under the Debentures shall operate as a waiver thereof; nor shall any
      single or partial exercise of any right, power or privilege hereunder or
      thereunder preclude any other or further exercise thereof or the exercise
      of any other right, power or privilege.

            (b) All of the rights and remedies of the Secured Parties with
      respect to the Collateral, whether established hereby or by the
      Debentures, the November Notes or by any other agreements, instruments or
      documents or by law shall be cumulative and may be exercised singly or
      concurrently.

            (c) This Agreement constitutes the entire agreement of the parties
      with respect to the subject matter hereof and is intended to supersede all
      prior negotiations, understandings and agreements with respect thereto.
      Except as specifically set forth in this Agreement, no provision of this
      Agreement may be modified or amended except by a written agreement
      specifically referring to this Agreement and signed by the Agent,
      Qualified Purchasers (as defined in the Purchase Agreement) and the
      Company.

            (d) In 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 Agreement is held to be invalid,
      prohibited or unenforceable 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.


                                       20
<PAGE>

            (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.

            (f) This Agreement shall be binding upon and inure to the benefit of
      each party hereto and its successors and assigns.

            (g) Each party shall take such further action and execute and
      deliver such further documents as may be necessary or appropriate in order
      to carry out the provisions and purposes of this Agreement.

            (h) All questions concerning the construction, validity, enforcement
      and interpretation of this Agreement shall be governed by and construed
      and enforced in accordance with the internal laws of the State of New
      York, without regard to the principles of conflicts of law thereof. Each
      Debtor agrees that all proceedings concerning the interpretations,
      enforcement and defense of the transactions contemplated by this Agreement
      and the Debentures (whether brought against a party hereto or its
      respective affiliates, directors, officers, shareholders, partners,
      members, employees or agents) shall be commenced exclusively in the state
      and federal courts sitting in the City of New York, Borough of Manhattan.
      Each Debtor hereby irrevocably submits to the exclusive jurisdiction of
      the state and federal courts sitting in the City of New York, Borough of
      Manhattan for the adjudication of any dispute hereunder or in connection
      herewith or with any transaction contemplated hereby or discussed herein,
      and hereby irrevocably waives, and agrees not to assert in any proceeding,
      any claim that it is not personally subject to the jurisdiction of any
      such court, that such proceeding is improper. Each party hereto hereby
      irrevocably waives personal service of process and consents to process
      being served in any such proceeding by mailing a copy thereof via
      registered or certified mail or overnight delivery (with evidence of
      delivery) to such party at the address in effect for notices to it under
      this Agreement and agrees that such service shall constitute good and
      sufficient service of process and notice thereof. Nothing contained herein
      shall be deemed to limit in any way any right to serve process in any
      manner permitted by law. Each party hereto hereby irrevocably waives, to
      the fullest extent permitted by applicable law, any and all right to trial
      by jury in any legal proceeding arising out of or relating to this
      Agreement or the transactions contemplated hereby. If any party shall
      commence a proceeding to enforce any provisions of this Agreement, then
      the prevailing party in such proceeding shall be reimbursed by the other
      party for its reasonable attorney's fees and other costs and expenses
      incurred with the investigation, preparation and prosecution of such
      proceeding.

            (i) This Agreement may be executed in any number of counterparts,
      each of which when so executed shall be deemed to be an original and, all
      of which taken together shall constitute one and the same Agreement. In
      the event that any signature is delivered by facsimile transmission, such
      signature shall create a valid binding obligation of the party executing
      (or on whose behalf such signature is executed) the same with the same
      force and effect as if such facsimile signature were the original thereof.


                                       21
<PAGE>

            (j) All Debtors shall jointly and severally be liable for the
      obligations of each Debtor to the Secured Parties hereunder.

            (k) Each Debtor shall indemnify, reimburse and hold harmless the
      Agent and the Secured Parties and their respective partners, members,
      shareholders, officers, directors, employees and agents (and any other
      persons with other titles that have similar functions) (collectively,
      "Indemnitees") from and against any and all losses, claims, liabilities,
      damages, penalties, suits, costs and expenses, of any kind or nature,
      (including reasonable fees relating to the cost of investigating and
      defending any of the foregoing) imposed on, incurred by or asserted
      against such Indemnitee in any way related to or arising from or alleged
      to arise from this Agreement or the Collateral, except any such losses,
      claims, liabilities, damages, penalties, suits, costs and expenses which
      result from the gross negligence or willful misconduct of the Indemnitee
      as determined by a final, nonappealable decision of a court of competent
      jurisdiction. This indemnification provision is in addition to, and not in
      limitation of, any other indemnification provision in the Debentures, the
      November Notes, the Purchase Agreement or any other agreement, instrument
      or other document executed or delivered in connection herewith or
      therewith.

            (l) Nothing in this Agreement shall be construed to subject Agent or
      any Secured Party to liability as a partner in any Debtor or any if its
      direct or indirect subsidiaries that is a partnership or as a member in
      any Debtor or any of its direct or indirect subsidiaries that is a limited
      liability company, nor shall Agent or any Secured Party be deemed to have
      assumed any obligations under any partnership agreement or limited
      liability company agreement, as applicable, of any such Debtor or any if
      its direct or indirect subsidiaries or otherwise, unless and until any
      such Secured Party exercises its right to be substituted for such Debtor
      as a partner or member, as applicable, pursuant hereto.

            (m) To the extent that the grant of the security interest in the
      Collateral and the enforcement of the terms hereof require the consent,
      approval or action of any partner or member, as applicable, of any Debtor
      or any direct or indirect subsidiary of any Debtor or compliance with any
      provisions of any of the Organizational Documents, the Debtors hereby
      grant such consent and approval and waive any such noncompliance with the
      terms of said documents.

            (n) This Agreement supersedes and replaces any prior security
      agreements or understandings regarding any of the Collateral entered into
      between the Company and any of the Secured Parties, including the Prior
      Security Agreement.

                                    SECURITY
                                    AGREEMENT

                                    THE AGENT

            1. Appointment. The Secured Parties (all capitalized terms used
herein and not otherwise defined shall have the respective meanings provided in
the Security Agreement to which this Annex B is attached (the "Agreement")), by
their acceptance of the benefits of the Agreement, hereby designate Midsummer
Investment Ltd. ("Midsummer" or "Agent") as the Agent to act as specified herein
and in the Agreement. Each Secured Party shall be deemed irrevocably to
authorize the Agent to take such action on its behalf under the provisions of
the Agreement and any other Transaction Document (as such term is defined in the
Debentures) and to exercise such powers and to perform such duties hereunder and
thereunder as are specifically delegated to or required of the Agent by the
terms hereof and thereof and such other powers as are reasonably incidental
thereto. The Agent may perform any of its duties hereunder by or through its
agents or employees.

            2. Nature of Duties. The Agent shall have no duties or
responsibilities except those expressly set forth in the Agreement. Neither the
Agent nor any of its partners, members, shareholders, officers, directors,
employees or agents shall be liable for any action taken or omitted by it as
such under the Agreement or hereunder or in connection herewith or therewith, be
responsible for the consequence of any oversight or error of judgment or
answerable for any loss, unless caused solely by its or their gross negligence
or willful conduct as determined by a final judgment (not subject to further
appeal) of a court of competent jurisdiction. The duties of the Agent shall be
mechanical and administrative in nature; the Agent shall not have by reason of
the Agreement or any other Transaction Document a fiduciary relationship in
respect of any Debtor or any Secured Party; and nothing in the Agreement or any
other Transaction Document, expressed or implied, is intended to or shall be so
construed as to impose upon the Agent any obligations in respect of the
Agreement or any other Transaction Document except as expressly set forth herein
and therein.

            3. Lack of Reliance on the Agent. Independently and without reliance
upon the Agent, each Secured Party, to the extent it deems appropriate, has made
and shall continue to make (i) its own independent investigation of the
financial condition and affairs of the Company and its subsidiaries in
connection with such Secured Party's investment in the Debtors, the creation and
continuance of the Obligations, the transactions contemplated by the Transaction
Documents, and the taking or not taking of any action in connection therewith,
and (ii) its own appraisal of the creditworthiness of the Company and its
subsidiaries, and of the value of the Collateral from time to time, and the
Agent shall have no duty or responsibility, either initially or on a continuing
basis, to provide any Secured Party with any credit, market or other information
with respect thereto, whether coming into its possession before any Obligations
are incurred or at any time or times thereafter. The Agent shall not be
responsible to the Debtors or any Secured Party for any recitals, statements,
information, representations or warranties herein or in any document,
certificate or other writing delivered in connection herewith, or for the
execution, effectiveness, genuineness, validity, enforceability, perfection,
collectibility, priority or sufficiency of the Agreement or any other
Transaction Document, or for the financial condition of the Debtors or the value
of any of the Collateral, or be required to make any inquiry concerning either
the performance or observance of any of the terms, provisions or conditions of
the Agreement or any other Transaction Document, or the financial condition of
the Debtors, or the value of any of the Collateral, or the existence or possible
existence of any default or Event of Default under the Agreement, the Debentures
or any of the other Transaction Documents.

            4. Certain Rights of the Agent. The Agent shall have the right to
take any action with respect to the Collateral, on behalf of all of the Secured
Parties. To the extent practical, the Agent shall request instructions from the
Secured Parties with respect to any material act or action (including failure to
act) in connection with the Agreement or any other Transaction Document, and
shall be entitled to act or refrain from acting in accordance with the
instructions of Secured Parties holding a majority in principal amount of
Debentures (based on then-outstanding principal amounts of Debentures at the
time of any such determination); if such instructions are not provided despite
the Agent's request therefor, the Agent shall be entitled to refrain from such
act or taking such action, and if such action is taken, shall be entitled to
appropriate indemnification from the Secured Parties in respect of actions to be
taken by the Agent; and the Agent shall not incur liability to any person or
entity by reason of so refraining. Without limiting the foregoing, (a) no
Secured Party shall have any right of action whatsoever against the Agent as a
result of the Agent acting or refraining from acting hereunder in accordance
with the terms of the Agreement or any other Transaction Document, and the
Debtors shall have no right to question or challenge the authority of, or the
instructions given to, the Agent pursuant to the foregoing and (b) the Agent
shall not be required to take any action which the Agent believes (i) could
reasonably be expected to expose it to personal liability or (ii) is contrary to
this Agreement, the Transaction Documents or applicable law.

            5. Reliance. The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, statement,
certificate, telex, teletype or telecopier message, cablegram, radiogram, order
or other document or telephone message signed, sent or made by the proper person
or entity, and, with respect to all legal matters pertaining to the Agreement
and the other Transaction Documents and its duties thereunder, upon advice of
counsel selected by it and upon all other matters pertaining to this Agreement
and the other Transaction Documents and its duties thereunder, upon advice of
other experts selected by it.

            6. Indemnification. To the extent that the Agent is not reimbursed
and indemnified by the Debtors, the Secured Parties will jointly and severally
reimburse and indemnify the Agent, in proportion to their initially purchased
respective principal amounts of Debentures, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in performing its duties
hereunder or under the Agreement or any other Transaction Document, or in any
way relating to or arising out of the Agreement or any other Transaction
Document except for those determined by a final judgment (not subject to further
appeal) of a court of competent jurisdiction to have resulted solely from the
Agent's own gross negligence or willful misconduct. Prior to taking any action
hereunder as Agent, the Agent may require each Secured Party to deposit with it
sufficient sums as it determines in good faith is necessary to protect the Agent
for costs and expenses associated with taking such action.

            7. Resignation by the Agent.

            (a) The Agent may resign from the performance of all its functions
      and duties under the Agreement and the other Transaction Documents at any
      time by giving 30 days' prior written notice (as provided in the
      Agreement) to the Debtors and the Secured Parties. Such resignation shall
      take effect upon the appointment of a successor Agent pursuant to clauses
      (b) and (c) below.

            (b) Upon any such notice of resignation, the Secured Parties, acting
      by a Majority in Interest, shall appoint a successor Agent hereunder.

            (c) If a successor Agent shall not have been so appointed within
      said 30-day period, the Agent shall then appoint a successor Agent who
      shall serve as Agent until such time, if any, as the Secured Parties
      appoint a successor Agent as provided above. If a successor Agent has not
      been appointed within such 30-day period, the Agent may petition any court
      of competent jurisdiction or may interplead the Debtors and the Secured
      Parties in a proceeding for the appointment of a successor Agent, and all
      fees, including, but not limited to, extraordinary fees associated with
      the filing of interpleader and expenses associated therewith, shall be
      payable by the Debtors on demand.

            8. Rights with respect to Collateral. Each Secured Party agrees with
all other Secured Parties and the Agent (i) that it shall not, and shall not
attempt to, exercise any rights with respect to its security interest in the
Collateral, whether pursuant to any other agreement or otherwise (other than
pursuant to this Agreement), or take or institute any action against the Agent
or any of the other Secured Parties in respect of the Collateral or its rights
hereunder (other than any such action arising from the breach of this Agreement)
and (ii) that such Secured Party has no other rights with respect to the
Collateral other than as set forth in this Agreement and the other Transaction
Documents.
