HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM

ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN
AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE

                          COMMON STOCK PURCHASE WARRANT

               To Purchase __________ Shares of Common Stock of

                          TNX Television Holdings, Inc.

            THIS COMMON STOCK PURCHASE WARRANT (the "Warrant") certifies that,
for value received, _____________ (the "Holder"), is entitled, upon the terms
and subject to the limitations on exercise and the conditions hereinafter set
forth, at any time on or after the date hereof (the "Initial Exercise Date") and
on or prior to the close of business on the three year anniversary of the
Initial Exercise Date (the "Termination Date") but not thereafter, to subscribe
for and purchase from TNX Television Holdings, Inc., a Delaware corporation (the
"Company"), up to ______ shares (the "Warrant Shares") of Common Stock, par
value $0.001 per share, of the Company (the "Common Stock"). The purchase price
of one share of Common Stock under this Warrant shall be equal to the Exercise
Price, as defined in Section 2(b).

      Section 1. Definitions. Capitalized terms used and not otherwise defined
herein shall have the meanings set forth in that certain Securities Purchase
Agreement (the "Purchase Agreement"), dated April 6, 2005, among the Company and
the purchasers signatory thereto.

      Section 2. Exercise.

            a) Exercise of Warrant. Exercise of the purchase rights represented
      by this Warrant may be made, in whole or in part, at any time or times on
      or after the Initial Exercise Date and on or before the Termination Date
      by delivery to the Company of a duly executed facsimile copy of the Notice
      of Exercise Form annexed hereto (or such other office or agency of the
      Company as it may designate by notice in writing to the registered Holder
      at the address of such Holder appearing on the books of the Company);
      provided, however, within 5 Trading Days of the date said Notice of
      Exercise is delivered to the Company, the Holder shall have surrendered
      this Warrant to the Company and the Company shall have received payment of
      the aggregate Exercise Price of the shares thereby purchased by wire
      transfer or cashier's check drawn on a United States bank.

                                       1
<PAGE>

            b) Exercise Price. The exercise price of the Common Stock under this
      Warrant shall be $0.30, subject to adjustment hereunder (the "Exercise
      Price").

            c) Cashless Exercise. If at any time after one year from the date of
      issuance of this Warrant there is no effective Registration Statement
      registering, or no current prospectus available for, the resale of the
      Warrant Shares by the Holder, then this Warrant may also be exercised at
      such time by means of a "cashless exercise" in which the Holder shall be
      entitled to receive a certificate for the number of Warrant Shares equal
      to the quotient obtained by dividing [(A-B) (X)] by (A), where:

            (A) = the VWAP on the Trading Day immediately preceding the date of
                  such election;

            (B) = the Exercise Price of this Warrant, as adjusted; and

            (X) = the number of Warrant Shares issuable upon exercise of this
                  Warrant in accordance with the terms of this Warrant by means
                  of a cash exercise rather than a cashless exercise.

            Notwithstanding anything herein to the contrary, on the Termination
      Date, this Warrant shall be automatically exercised via cashless exercise
      pursuant to this Section 2(c).

            d) Exercise Limitations; Holder's Restrictions. The Holder shall not
      have the right to exercise any portion of this Warrant, pursuant to
      Section 2(c) or otherwise, to the extent that after giving effect to such
      issuance after exercise, the Holder (together with the Holder's
      affiliates), as set forth on the applicable Notice of Exercise, would
      beneficially own in excess of 4.99% of the number of shares of the Common
      Stock outstanding immediately after giving effect to such issuance. For
      purposes of the foregoing sentence, the number of shares of Common Stock
      beneficially owned by the Holder and its affiliates shall include the
      number of shares of Common Stock issuable upon exercise of this Warrant
      with respect to which the determination of such sentence is being made,
      but shall exclude the number of shares of Common Stock which would be
      issuable upon (A) exercise of the remaining, nonexercised portion of this
      Warrant beneficially owned by the Holder or any of its affiliates and (B)
      exercise or conversion of the unexercised or nonconverted portion of any
      other securities of the Company (including, without limitation, any other
      Debentures or Warrants) subject to a limitation on conversion or exercise
      analogous to the limitation contained herein beneficially owned by the
      Holder or any of its affiliates. Except as set forth in the preceding
      sentence, for purposes of this Section 2(d), beneficial ownership shall be
      calculated in accordance with Section 13(d) of the Exchange Act, it being

                                       2
<PAGE>

      acknowledged by Holder that the Company is not representing to Holder that
      such calculation is in compliance with Section 13(d) of the Exchange Act
      and Holder is solely responsible for any schedules required to be filed in
      accordance therewith. To the extent that the limitation contained in this
      Section 2(d) applies, the determination of whether this Warrant is
      exercisable (in relation to other securities owned by the Holder) and of
      which a portion of this Warrant is exercisable shall be in the sole
      discretion of such Holder, and the submission of a Notice of Exercise
      shall be deemed to be such Holder's determination of whether this Warrant
      is exercisable (in relation to other securities owned by such Holder) and
      of which portion of this Warrant is exercisable, in each case subject to
      such aggregate percentage limitation, and the Company shall have no
      obligation to verify or confirm the accuracy of such determination. For
      purposes of this Section 2(d), in determining the number of outstanding
      shares of Common Stock, the Holder may rely on the number of outstanding
      shares of Common Stock as reflected in (x) the Company's most recent Form
      10-Q or Form 10-K, as the case may be, (y) a more recent public
      announcement by the Company or (z) any other notice by the Company or the
      Company's Transfer Agent setting forth the number of shares of Common
      Stock outstanding. Upon the written or oral request of the Holder, the
      Company shall within two Trading Days confirm orally and in writing to the
      Holder the number of shares of Common Stock then outstanding. In any case,
      the number of outstanding shares of Common Stock shall be determined after
      giving effect to the conversion or exercise of securities of the Company,
      including this Warrant, by the Holder or its affiliates since the date as
      of which such number of outstanding shares of Common Stock was reported.
      The provisions of this Section 2(d) may be waived by the Holder, at the
      election of the Holder, upon not less than 61 days' prior notice to the
      Company, and the provisions of this Section 2(d) shall continue to apply
      until such 61st day (or such later date, as determined by the Holder, as
      may be specified in such notice of waiver).

            e) Mechanics of Exercise.

                  i. Authorization of Warrant Shares. The Company covenants that
            all Warrant Shares which may be issued upon the exercise of the
            purchase rights represented by this Warrant will, upon exercise of
            the purchase rights represented by this Warrant, be duly authorized,
            validly issued, fully paid and nonassessable and free from all
            taxes, liens and charges in respect of the issue thereof (other than
            taxes in respect of any transfer occurring contemporaneously with
            such issue).

                  ii. Delivery of Certificates Upon Exercise. Certificates for
            shares purchased hereunder shall be transmitted by the transfer
            agent of the Company to the Holder by crediting the account of the
            Holder's prime broker with the Depository Trust Company through its
            Deposit Withdrawal Agent Commission ("DWAC") system if the Company
            is a participant in such system, and otherwise by physical delivery
            to the address specified by the Holder in the Notice of Exercise
            within 3 Trading Days from the delivery to the Company of the Notice
            of Exercise Form, surrender of this Warrant and payment of the
            aggregate Exercise Price as set forth above ("Warrant Share Delivery
            Date"). This Warrant shall be deemed to have been exercised on the
            date the Exercise Price is received by the Company. The Warrant

                                       3
<PAGE>

            Shares shall be deemed to have been issued, and Holder or any other
            person so designated to be named therein shall be deemed to have
            become a holder of record of such shares for all purposes, as of the
            date the Warrant has been exercised by payment to the Company of the
            Exercise Price and all taxes required to be paid by the Holder, if
            any, pursuant to Section 2(e)(vii) prior to the issuance of such
            shares, have been paid.

                  iii. Delivery of New Warrants Upon Exercise. If this Warrant
            shall have been exercised in part, the Company shall, at the time of
            delivery of the certificate or certificates representing Warrant
            Shares, deliver to Holder a new Warrant evidencing the rights of
            Holder to purchase the unpurchased Warrant Shares called for by this
            Warrant, which new Warrant shall in all other respects be identical
            with this Warrant.

                  iv. Rescission Rights. If the Company fails to cause its
            transfer agent to transmit to the Holder a certificate or
            certificates representing the Warrant Shares pursuant to this
            Section 2(e)(iv) by the Warrant Share Delivery Date, then the Holder
            will have the right to rescind such exercise.

                  v. Compensation for Buy-In on Failure to Timely Deliver
            Certificates Upon Exercise. In addition to any other rights
            available to the Holder, if the Company fails to cause its transfer
            agent to transmit to the Holder a certificate or certificates
            representing the Warrant Shares pursuant to an exercise on or before
            the Warrant Share Delivery Date, and if after such date the Holder
            is required by its broker to purchase (in an open market transaction
            or otherwise) shares of Common Stock to deliver in satisfaction of a
            sale by the Holder of the Warrant Shares which the Holder
            anticipated receiving upon such exercise (a "Buy-In"), then the
            Company shall (1) pay in cash to the Holder the amount by which (x)
            the Holder's total purchase price (including brokerage commissions,
            if any) for the shares of Common Stock so purchased exceeds (y) the
            amount obtained by multiplying (A) the number of Warrant Shares that
            the Company was required to deliver to the Holder in connection with
            the exercise at issue times (B) the price at which the sell order
            giving rise to such purchase obligation was executed, and (2) at the
            option of the Holder, either reinstate the portion of the Warrant
            and equivalent number of Warrant Shares for which such exercise was
            not honored or deliver to the Holder the number of shares of Common
            Stock that would have been issued had the Company timely complied
            with its exercise and delivery obligations hereunder. For example,
            if the Holder purchases Common Stock having a total purchase price
            of $11,000 to cover a Buy-In with respect to an attempted exercise
            of shares of Common Stock with an aggregate sale price giving rise
            to such purchase obligation of $10,000, under clause (1) of the
            immediately preceding sentence the Company shall be required to pay
            the Holder $1,000. The Holder shall provide the Company written
            notice indicating the amounts payable to the Holder in respect of

                                       4
<PAGE>

            the Buy-In, together with applicable confirmations and other
            evidence reasonably requested by the Company. Nothing herein shall
            limit a Holder's right to pursue any other remedies available to it
            hereunder, at law or in equity including, without limitation, a
            decree of specific performance and/or injunctive relief with respect
            to the Company's failure to timely deliver certificates representing
            shares of Common Stock upon exercise of the Warrant as required
            pursuant to the terms hereof.

                  vi. No Fractional Shares or Scrip. No fractional shares or
            scrip representing fractional shares shall be issued upon the
            exercise of this Warrant. As to any fraction of a share which Holder
            would otherwise be entitled to purchase upon such exercise, the
            Company shall pay a cash adjustment in respect of such final
            fraction in an amount equal to such fraction multiplied by the
            Exercise Price.

                  vii. Charges, Taxes and Expenses. Issuance of certificates for
            Warrant Shares shall be made without charge to the Holder for any
            issue or transfer tax or other incidental expense in respect of the
            issuance of such certificate, all of which taxes and expenses shall
            be paid by the Company, and such certificates shall be issued in the
            name of the Holder or in such name or names as may be directed by
            the Holder; provided, however, that in the event certificates for
            Warrant Shares are to be issued in a name other than the name of the
            Holder, this Warrant when surrendered for exercise shall be
            accompanied by the Assignment Form attached hereto duly executed by
            the Holder; and the Company may require, as a condition thereto, the
            payment of a sum sufficient to reimburse it for any transfer tax
            incidental thereto.

                  viii. Closing of Books. The Company will not close its
            stockholder books or records in any manner which prevents the timely
            exercise of this Warrant, pursuant to the terms hereof.

            f) Call Provision. Subject to the provisions of Section 2(d) and
      this Section 2(f), if after the later of the Shareholder Approval Date and
      the Effective Date the VWAP for each of 30 consecutive Trading Days (the
      "Measurement Period", which period shall not have commenced until after
      the Effective Date) exceeds $1.00 (subject to adjustment for forward and
      reverse stock splits, recapitalizations, stock dividends and the like
      after the Initial Exercise Date) (the "Threshold Price"), then the Company
      may, within five Trading Days of the end of such period, call for
      cancellation of all or any portion of this Warrant for which a Notice of
      Exercise has not yet been delivered (such right, a "Call"). To exercise
      this right, the Company must deliver to the Holder an irrevocable written
      notice (a "Call Notice"), indicating therein the portion of unexercised
      portion of this Warrant to which such notice applies. If the conditions
      set forth below for such Call are satisfied from the period from the date
      of the Call Notice through and including the Call Date (as defined below),
      then any portion of this Warrant subject to such Call Notice for which a
      Notice of Exercise shall not have been received by the Call Date will be

                                       5
<PAGE>

      cancelled at 6:30 p.m. (New York City time) on the tenth Trading Day after
      the date the Call Notice is received by the Holder (such date, the "Call
      Date"). Any unexercised portion of this Warrant to which the Call Notice
      does not pertain will be unaffected by such Call Notice. In furtherance
      thereof, the Company covenants and agrees that it will honor all Notices
      of Exercise with respect to Warrant Shares subject to a Call Notice that
      are tendered through 6:30 p.m. (New York City time) on the Call Date. The
      parties agree that any Notice of Exercise delivered following a Call
      Notice shall first reduce to zero the number of Warrant Shares subject to
      such Call Notice prior to reducing the remaining Warrant Shares available
      for purchase under this Warrant. For example, if (x) this Warrant then
      permits the Holder to acquire 100 Warrant Shares, (y) a Call Notice
      pertains to 75 Warrant Shares, and (z) prior to 6:30 p.m. (New York City
      time) on the Call Date the Holder tenders a Notice of Exercise in respect
      of 50 Warrant Shares, then (1) on the Call Date the right under this
      Warrant to acquire 25 Warrant Shares will be automatically cancelled, (2)
      the Company, in the time and manner required under this Warrant, will have
      issued and delivered to the Holder 50 Warrant Shares in respect of the
      exercises following receipt of the Call Notice, and (3) the Holder may,
      until the Termination Date, exercise this Warrant for 25 Warrant Shares
      (subject to adjustment as herein provided and subject to subsequent Call
      Notices). Subject again to the provisions of this Section 2(f), the
      Company may deliver subsequent Call Notices for any portion of this
      Warrant for which the Holder shall not have delivered a Notice of
      Exercise. Notwithstanding anything to the contrary set forth in this
      Warrant, the Company may not deliver a Call Notice or require the
      cancellation of this Warrant (and any Call Notice will be void), unless,
      from the beginning of the 30th consecutive Trading Days used to determine
      whether the Common Stock has achieved the Threshold Price through the Call
      Date, (i) the Company shall have honored in accordance with the terms of
      this Warrant all Notices of Exercise delivered by 6:30 p.m. (New York City
      time) on the Call Date, (ii) the Registration Statement shall be effective
      as to all Warrant Shares and the prospectus thereunder available for use
      by the Holder for the resale of all such Warrant Shares and (iii) the
      Common Stock shall be listed or quoted for trading on the Trading Market.
      The Company's right to Call the Warrant shall be exercised ratably among
      the Holders based on each Holder's initial purchase of Common Stock
      pursuant to the Purchase Agreement.

      Section 3. Certain Adjustments.

            a) Stock Dividends and Splits. If the Company, at any time while
      this Warrant is outstanding: (A) pays a stock dividend or otherwise make a
      distribution or distributions on shares of its Common Stock or any other
      equity or equity equivalent securities payable in shares of Common Stock
      (which, for avoidance of doubt, shall not include any shares of Common
      Stock issued by the Company pursuant to this Warrant), (B) subdivides
      outstanding shares of Common Stock into a larger number of shares, (C)
      combines (including by way of reverse stock split) outstanding shares of
      Common Stock into a smaller number of shares, or (D) issues by
      reclassification of shares of the Common Stock any shares of capital stock
      of the Company, then in each case the Exercise Price shall be multiplied
      by a fraction of which the numerator shall be the number of shares of
      Common Stock (excluding treasury shares, if any) outstanding immediately
      before such event and of which the denominator shall be the number of
      shares of Common Stock outstanding immediately after such event and the

                                       6
<PAGE>

      number of shares issuable upon exercise of this Warrant shall be
      proportionately adjusted. Any adjustment made pursuant to this Section
      3(a) shall become effective immediately after the record date for the
      determination of stockholders entitled to receive such dividend or
      distribution and shall become effective immediately after the effective
      date in the case of a subdivision, combination or re-classification.

            b) Subsequent Equity Sales. If the Company or any Subsidiary
      thereof, as applicable, at any time while this Warrant is outstanding,
      shall offer, sell, grant any option to purchase or offer, sell or grant
      any right to reprice its securities, or otherwise dispose of or issue (or
      announce any offer, sale, grant or any option to purchase or other
      disposition) any Common Stock or Common Stock Equivalents entitling any
      Person to acquire shares of Common Stock, at an effective price per share
      less than the then Exercise Price (such lower price, the "Base Share
      Price" and such issuances collectively, a "Dilutive Issuance"), as
      adjusted hereunder (if the holder of the Common Stock or Common Stock
      Equivalents so issued shall at any time, whether by operation of purchase
      price adjustments, reset provisions, floating conversion, exercise or
      exchange prices or otherwise, or due to warrants, options or rights per
      share which is issued in connection with such issuance, be entitled to
      receive shares of Common Stock at an effective price per share which is
      less than the Exercise Price, such issuance shall be deemed to have
      occurred for less than the Exercise Price), then, the Exercise Price shall
      be reduced to equal the Base Share Price and the number of Warrant Shares
      issuable hereunder shall be increased such that the aggregate Exercise
      Price payable hereunder, after taking into account the decrease in the
      Exercise Price, shall be equal to the aggregate Exercise Price prior to
      such adjustment. Such adjustment shall be made whenever such Common Stock
      or Common Stock Equivalents are issued. The Company shall notify the
      Holder in writing, no later than the Trading Day following the issuance of
      any Common Stock or Common Stock Equivalents subject to this section,
      indicating therein the applicable issuance price, or of applicable reset
      price, exchange price, conversion price and other pricing terms (such
      notice the "Dilutive Issuance Notice"). For purposes of clarification,
      whether or not the Company provides a Dilutive Issuance Notice pursuant to
      this Section 3(b), upon the occurrence of any Dilutive Issuance, after the
      date of such Dilutive Issuance the Holder is entitled to receive a number
      of Warrant Shares based upon the Base Share Price regardless of whether
      the Holder accurately refers to the Base Share Price in the Notice of
      Exercise.

            c) Pro Rata Distributions. If the Company, at any time prior to the
      Termination Date, shall distribute to all holders of Common Stock (and not
      to Holders of the Warrants) evidences of its indebtedness or assets
      (including cash and cash dividends) or rights or warrants to subscribe for
      or purchase any security other than the Common Stock (which shall be
      subject to Section 3(b)), then in each such case the Exercise Price shall
      be adjusted by multiplying the Exercise Price in effect immediately prior
      to the record date fixed for determination of stockholders entitled to
      receive such distribution by a fraction of which the denominator shall be
      the VWAP determined as of the record date mentioned above, and of which
      the numerator shall be such VWAP on such record date less the then per
      share fair market value at such record date of the portion of such assets
      or evidence of indebtedness so distributed applicable to one outstanding
      share of the Common Stock as determined by the Board of Directors in good
      faith. In either case the adjustments shall be described in a statement

                                       7
<PAGE>

      provided to the Holder of the portion of assets or evidences of
      indebtedness so distributed or such subscription rights applicable to one
      share of Common Stock. Such adjustment shall be made whenever any such
      distribution is made and shall become effective immediately after the
      record date mentioned above.

            d) Fundamental Transaction. If, at any time while this Warrant is
      outstanding, (A) the Company effects any merger or consolidation of the
      Company with or into another Person, (B) the Company effects any sale of
      all or substantially all of its assets in one or a series of related
      transactions, (C) any tender offer or exchange offer (whether by the
      Company or another Person) is completed pursuant to which holders of
      Common Stock are permitted to tender or exchange their shares for other
      securities, cash or property, or (D) the Company effects any
      reclassification of the Common Stock or any compulsory share exchange
      pursuant to which the Common Stock is effectively converted into or
      exchanged for other securities, cash or property (in any such case, a
      "Fundamental Transaction"), then, upon any subsequent exercise of this
      Warrant, the Holder shall have the right to receive, for each Warrant
      Share that would have been issuable upon such exercise immediately prior
      to the occurrence of such Fundamental Transaction, at the option of the
      Holder, (a) upon exercise of this Warrant, the number of shares of Common
      Stock of the successor or acquiring corporation or of the Company, if it
      is the surviving corporation, and Alternate Consideration receivable upon
      or as a result of such reorganization, reclassification, merger,
      consolidation or disposition of assets by a Holder of the number of shares
      of Common Stock for which this Warrant is exercisable immediately prior to
      such event or (b) if the Company is acquired in an all cash transaction,
      cash equal to the value of this Warrant as determined in accordance with
      the Black-Scholes option pricing formula (the "Alternate Consideration").
      For purposes of any such exercise, the determination of the Exercise Price
      shall be appropriately adjusted to apply to such Alternate Consideration
      based on the amount of Alternate Consideration issuable in respect of one
      share of Common Stock in such Fundamental Transaction, and the Company
      shall apportion the Exercise Price among the Alternate Consideration in a
      reasonable manner reflecting the relative value of any different
      components of the Alternate Consideration. If holders of Common Stock are
      given any choice as to the securities, cash or property to be received in
      a Fundamental Transaction, then the Holder shall be given the same choice
      as to the Alternate Consideration it receives upon any exercise of this
      Warrant following such Fundamental Transaction. To the extent necessary to
      effectuate the foregoing provisions, any successor to the Company or
      surviving entity in such Fundamental Transaction shall issue to the Holder
      a new warrant consistent with the foregoing provisions and evidencing the
      Holder's right to exercise such warrant into Alternate Consideration. The
      terms of any agreement pursuant to which a Fundamental Transaction is
      effected shall include terms requiring any such successor or surviving
      entity to comply with the provisions of this Section 3(d) and insuring
      that this Warrant (or any such replacement security) will be similarly
      adjusted upon any subsequent transaction analogous to a Fundamental
      Transaction.

            e) Exempt Issuance. Notwithstanding the foregoing, no adjustments,
      Alternate Consideration nor notices shall be made, paid or issued under
      this Section 3 in respect of an Exempt Issuance.

                                       8
<PAGE>

            f) Calculations. All calculations under this Section 3 shall be made
      to the nearest cent or the nearest 1/100th of a share, as the case may be.
      For purposes of this Section 3, the number of shares of Common Stock
      deemed to be issued and outstanding as of a given date shall be the sum of
      the number of shares of Common Stock (excluding treasury shares, if any)
      issued and outstanding.

            g) Voluntary Adjustment By Company. The Company may at any time
      during the term of this Warrant reduce the then current Exercise Price to
      any amount and for any period of time deemed appropriate by the Board of
      Directors of the Company.

            h) Notice to Holders.

                  i. Adjustment to Exercise Price. Whenever the Exercise Price
            is adjusted pursuant to this Section 3, the Company shall promptly
            mail to each Holder a notice setting forth the Exercise Price after
            such adjustment and setting forth a brief statement of the facts
            requiring such adjustment. If the Company issues a variable rate
            security, despite the prohibition thereon in the Purchase Agreement,
            the Company shall be deemed to have issued Common Stock or Common
            Stock Equivalents at the lowest possible conversion or exercise
            price at which such securities may be converted or exercised in the
            case of a Variable Rate Transaction (as defined in the Purchase
            Agreement), or the lowest possible adjustment price in the case of
            an MFN Transaction (as defined in the Purchase Agreement.

                  ii. Notice to Allow Exercise by Holder. If (A) the Company
            shall declare a dividend (or any other distribution) on the Common
            Stock; (B) the Company shall declare a special nonrecurring cash
            dividend on or a redemption of the Common Stock; (C) the Company
            shall authorize the granting to all holders of the Common Stock
            rights or warrants to subscribe for or purchase any shares of
            capital stock of any class or of any rights; (D) the approval of any
            stockholders of the Company shall be required in connection with any
            reclassification of the Common Stock, any consolidation or merger to
            which the Company is a party, any sale or transfer of all or
            substantially all of the assets of the Company, of any compulsory
            share exchange whereby the Common Stock is converted into other
            securities, cash or property; (E) the Company shall authorize the
            voluntary or involuntary dissolution, liquidation or winding up of
            the affairs of the Company; then, in each case, the Company shall
            cause to be mailed to the Holder at its last address as it shall
            appear upon the Warrant Register of the Company, at least 20
            calendar days prior to the applicable record or effective date
            hereinafter specified, a notice stating (x) the date on which a
            record is to be taken for the purpose of such dividend,
            distribution, redemption, rights or warrants, or if a record is not
            to be taken, the date as of which the holders of the Common Stock of
            record to be entitled to such dividend, distributions, redemption,
            rights or warrants are to be determined or (y) the date on which

                                       9
<PAGE>

            such reclassification, consolidation, merger, sale, transfer or
            share exchange is expected to become effective or close, and the
            date as of which it is expected that holders of the Common Stock of
            record shall be entitled to exchange their shares of the Common
            Stock for securities, cash or other property deliverable upon such
            reclassification, consolidation, merger, sale, transfer or share
            exchange; provided, that the failure to mail such notice or any
            defect therein or in the mailing thereof shall not affect the
            validity of the corporate action required to be specified in such
            notice. The Holder is entitled to exercise this Warrant (or any part
            hereof) during the 20-day period commencing on the date of such
            notice to the effective date of the event triggering such notice.

      Section 4. Transfer of Warrant.

            a) Transferability. Subject to compliance with any applicable
      securities laws and the conditions set forth in Sections 5(a) and 4(d)
      hereof and to the provisions of Section 4.1 of the Purchase Agreement,
      this Warrant and all rights hereunder are transferable, in whole or in
      part, upon surrender of this Warrant at the principal office of the
      Company, together with a written assignment of this Warrant substantially
      in the form attached hereto duly executed by the Holder or its agent or
      attorney and funds sufficient to pay any transfer taxes payable upon the
      making of such transfer. Upon such surrender and, if required, such
      payment, the Company shall execute and deliver a new Warrant or Warrants
      in the name of the assignee or assignees and in the denomination or
      denominations specified in such instrument of assignment, and shall issue
      to the assignor a new Warrant evidencing the portion of this Warrant not
      so assigned, and this Warrant shall promptly be cancelled. A Warrant, if
      properly assigned, may be exercised by a new holder for the purchase of
      Warrant Shares without having a new Warrant issued.

            b) New Warrants. This Warrant may be divided or combined with other
      Warrants upon presentation hereof at the aforesaid office of the Company,
      together with a written notice specifying the names and denominations in
      which new Warrants are to be issued, signed by the Holder or its agent or
      attorney. Subject to compliance with Section 4(a), as to any transfer
      which may be involved in such division or combination, the Company shall
      execute and deliver a new Warrant or Warrants in exchange for the Warrant
      or Warrants to be divided or combined in accordance with such notice.

            c) Warrant Register. The Company shall register this Warrant, upon
      records to be maintained by the Company for that purpose (the "Warrant
      Register"), in the name of the record Holder hereof from time to time. The
      Company may deem and treat the registered Holder of this Warrant as the
      absolute owner hereof for the purpose of any exercise hereof or any
      distribution to the Holder, and for all other purposes, absent actual
      notice to the contrary.

            d) Transfer Restrictions. If, at the time of the surrender of this
      Warrant in connection with any transfer of this Warrant, the transfer of
      this Warrant shall not be registered pursuant to an effective registration
      statement under the Securities Act and under applicable state securities
      or blue sky laws, the Company may require, as a condition of allowing such

                                       10
<PAGE>

      transfer (i) that the Holder or transferee of this Warrant, as the case
      may be, furnish to the Company a written opinion of counsel (which opinion
      shall be in form, substance and scope customary for opinions of counsel in
      comparable transactions) to the effect that such transfer may be made
      without registration under the Securities Act and under applicable state
      securities or blue sky laws, (ii) that the holder or transferee execute
      and deliver to the Company an investment letter in form and substance
      acceptable to the Company and (iii) that the transferee be an "accredited
      investor" as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8)
      promulgated under the Securities Act or a qualified institutional buyer as
      defined in Rule 144A(a) under the Securities Act.

      Section 5. Miscellaneous.

            a) Title to Warrant. Prior to the Termination Date and subject to
      compliance with applicable laws and Section 4 of this Warrant, this
      Warrant and all rights hereunder are transferable, in whole or in part, at
      the office or agency of the Company by the Holder in person or by duly
      authorized attorney, upon surrender of this Warrant together with the
      Assignment Form annexed hereto properly endorsed. The transferee shall
      sign an investment letter in form and substance reasonably satisfactory to
      the Company.

            b) No Rights as Shareholder Until Exercise. This Warrant does not
      entitle the Holder to any voting rights or other rights as a shareholder
      of the Company prior to the exercise hereof. Upon the surrender of this
      Warrant and the payment of the aggregate Exercise Price (or by means of a
      cashless exercise), the Warrant Shares so purchased shall be and be deemed
      to be issued to such Holder as the record owner of such shares as of the
      close of business on the later of the date of such surrender or payment.

            c) Loss, Theft, Destruction or Mutilation of Warrant. The Company
      covenants that upon receipt by the Company of evidence reasonably
      satisfactory to it of the loss, theft, destruction or mutilation of this
      Warrant or any stock certificate relating to the Warrant Shares, and in
      case of loss, theft or destruction, of indemnity or security reasonably
      satisfactory to it (which, in the case of the Warrant, shall not include
      the posting of any bond), and upon surrender and cancellation of such
      Warrant or stock certificate, if mutilated, the Company will make and
      deliver a new Warrant or stock certificate of like tenor and dated as of
      such cancellation, in lieu of such Warrant or stock certificate.

            d) Saturdays, Sundays, Holidays, etc. If the last or appointed day
      for the taking of any action or the expiration of any right required or
      granted herein shall be a Saturday, Sunday or a legal holiday, then such
      action may be taken or such right may be exercised on the next succeeding
      day not a Saturday, Sunday or legal holiday.

            e) Authorized Shares.

                  At any time after the Shareholder Approval Date, the Company
            covenants that during the period the Warrant is outstanding, it will
            reserve from its authorized and unissued Common Stock a sufficient
            number of shares to provide for the issuance of the Warrant Shares
            upon the exercise of any purchase rights under this Warrant. The

                                       11
<PAGE>

            Company further covenants that its issuance of this Warrant shall
            constitute full authority to its officers who are charged with the
            duty of executing stock certificates to execute and issue the
            necessary certificates for the Warrant Shares upon the exercise of
            the purchase rights under this Warrant. The Company will take all
            such reasonable action as may be necessary to assure that such
            Warrant Shares may be issued as provided herein without violation of
            any applicable law or regulation, or of any requirements of the
            Trading Market upon which the Common Stock may be listed.

                  Except and to the extent as waived or consented to by the
            Holder, the Company shall not by any action, including, without
            limitation, amending its certificate of incorporation or through any
            reorganization, transfer of assets, consolidation, merger,
            dissolution, issue or sale of securities or any other voluntary
            action, avoid or seek to avoid the observance or performance of any
            of the terms of this Warrant, but will at all times in good faith
            assist in the carrying out of all such terms and in the taking of
            all such actions as may be necessary or appropriate to protect the
            rights of Holder as set forth in this Warrant against impairment.
            Without limiting the generality of the foregoing, the Company will
            (a) not increase the par value of any Warrant Shares above the
            amount payable therefor upon such exercise immediately prior to such
            increase in par value, (b) take all such action as may be necessary
            or appropriate in order that the Company may validly and legally
            issue fully paid and nonassessable Warrant Shares upon the exercise
            of this Warrant, and (c) use commercially reasonable efforts to
            obtain all such authorizations, exemptions or consents from any
            public regulatory body having jurisdiction thereof as may be
            necessary to enable the Company to perform its obligations under
            this Warrant.

                  Before taking any action which would result in an adjustment
            in the number of Warrant Shares for which this Warrant is
            exercisable or in the Exercise Price, the Company shall obtain all
            such authorizations or exemptions thereof, or consents thereto, as
            may be necessary from any public regulatory body or bodies having
            jurisdiction thereof.

            f) Jurisdiction. All questions concerning the construction,
      validity, enforcement and interpretation of this Warrant shall be
      determined in accordance with the provisions of the Purchase Agreement.

            g) Restrictions. The Holder acknowledges that the Warrant Shares
      acquired upon the exercise of this Warrant, if not registered, will have
      restrictions upon resale imposed by state and federal securities laws.

            h) Nonwaiver and Expenses. No course of dealing or any delay or
      failure to exercise any right hereunder on the part of Holder shall
      operate as a waiver of such right or otherwise prejudice Holder's rights,
      powers or remedies, notwithstanding the fact that all rights hereunder
      terminate on the Termination Date. If the Company willfully and knowingly
      fails to comply with any provision of this Warrant, which results in any
      material damages to the Holder, the Company shall pay to Holder such
      amounts as shall be sufficient to cover any costs and expenses including,
      but not limited to, reasonable attorneys' fees, including those of
      appellate proceedings, incurred by Holder in collecting any amounts due
      pursuant hereto or in otherwise enforcing any of its rights, powers or
      remedies hereunder.

                                       12
<PAGE>

            i) Notices. Any notice, request or other document required or
      permitted to be given or delivered to the Holder by the Company shall be
      delivered in accordance with the notice provisions of the Purchase
      Agreement.

            j) Limitation of Liability. No provision hereof, in the absence of
      any affirmative action by Holder to exercise this Warrant or purchase
      Warrant Shares, and no enumeration herein of the rights or privileges of
      Holder, shall give rise to any liability of Holder for the purchase price
      of any Common Stock or as a stockholder of the Company, whether such
      liability is asserted by the Company or by creditors of the Company.

            k) Remedies. Holder, in addition to being entitled to exercise all
      rights granted by law, including recovery of damages, will be entitled to
      specific performance of its rights under this Warrant. The Company agrees
      that monetary damages would not be adequate compensation for any loss
      incurred by reason of a breach by it of the provisions of this Warrant and
      hereby agrees to waive the defense in any action for specific performance
      that a remedy at law would be adequate.

            l) Successors and Assigns. Subject to applicable securities laws,
      this Warrant and the rights and obligations evidenced hereby shall inure
      to the benefit of and be binding upon the successors of the Company and
      the successors and permitted assigns of Holder. The provisions of this
      Warrant are intended to be for the benefit of all Holders from time to
      time of this Warrant and shall be enforceable by any such Holder or holder
      of Warrant Shares.

            m) Amendment. This Warrant may be modified or amended or the
      provisions hereof waived with the written consent of the Company and the
      Holder.

            n) Severability. Wherever possible, each provision of this Warrant
      shall be interpreted in such manner as to be effective and valid under
      applicable law, but if any provision of this Warrant shall be prohibited
      by or invalid under applicable law, such provision shall be ineffective to
      the extent of such prohibition or invalidity, without invalidating the
      remainder of such provisions or the remaining provisions of this Warrant.

            o) Headings. The headings used in this Warrant are for the
      convenience of reference only and shall not, for any purpose, be deemed a
      part of this Warrant.

among TNX Television Holdings, Inc., a Delaware corporation (the "Company" or
the "Debtor") and the holder or holders of the Company's Secured Convertible
Debenture due April 6, 2007 in the original aggregate Principal Amount of up to
$5,000,000 (the "Debenture") and Warrants, signatory hereto, their endorsees,

<PAGE>

                  Without limiting the generality of the foregoing, the
            "Collateral" shall include all investment property and general
            intangibles respecting ownership and/or other equity interests in
            subsidiaries of the Company (the "Subsidiaries"), including, without
            limitation, the shares of capital stock and the other equity
            interests listed on Schedule H hereto (as the same may be modified
            from time to time pursuant to the terms hereof), and any other
            shares of capital stock and/or other equity interests of any other
            direct or indirect subsidiary of the Debtor obtained in the future,
            and, in each case, all certificates representing such shares and/or
            equity interests and, in each case, all rights, options, warrants,
            stock, other securities and/or equity interests that may hereafter
            be received, receivable or distributed in respect of, or exchanged
            for, any of the foregoing (all of the foregoing being referred to
            herein as the "Pledged Securities") and all rights arising under or
            in connection with the Pledged Securities, including, but not
            limited to, all dividends, interest and cash.

                  Notwithstanding 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 Sections 9-406, 9-407 and/or 9-408 of the UCC or other similar
            applicable law); provided, however, that to the extent permitted by
            applicable law, this Agreement shall create a valid security
            interest in such asset and, to the extent permitted by applicable
            law, this Agreement shall create a valid security interest in the
            proceeds of such asset.

            (b) "Intellectual Property" means the collective reference to all
      rights, priorities and privileges relating to intellectual property,
      whether arising under United States, multinational or foreign laws or
      otherwise, including, without limitation, (i) all copyrights arising under
      the laws of the United States, any other country or any political
      subdivision thereof, whether registered or unregistered and whether
      published or unpublished, all registrations and recordings thereof, and
      all applications in connection therewith, including, without limitation,
      all registrations, recordings and applications in the United States
      Copyright Office, (ii) all letters patent of the United States, any other
      country or any political subdivision thereof, all reissues and extensions
      thereof, and all applications for letters patent of the United States or
      any other country and all divisions, continuations and
      continuations-in-part thereof, (iii) all trademarks, trade names,
      corporate names, company names, business names, fictitious business names,
      trade dress, service marks, logos, domain names and other source or
      business identifiers, and all goodwill associated therewith, now existing
      or hereafter adopted or acquired, all registrations and recordings
      thereof, and all applications in connection therewith, whether in the
      United States Patent and Trademark Office or in any similar office or
      agency of the United States, any State thereof or any other country or any

<PAGE>

      political subdivision thereof, or otherwise, and all common law rights
      related thereto, (iv) all trade secrets arising under the laws of the
      United States, any other country or any political subdivision thereof, (v)
      all rights to obtain any reissues, renewals or extensions of the
      foregoing, (vi) all licenses for any of the foregoing, and (vii) all
      causes of action for infringement of the foregoing.

            (c) "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.

            (d) "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.

            (e) "Obligations" means all of the Debtor's obligations under this
      Agreement, the Purchase Agreement, the Debentures 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 loans extended
      pursuant thereto; (ii) any and all other fees, indemnities, costs,
      obligations and liabilities of the Debtor from time to time under or in
      connection with this Agreement, the Debentures and any other instruments,
      agreements or other documents executed and/or delivered 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 the Debtor.

(f)   "Organizational  Documents"  means  with  respect  to  the  Debtor,  the
      documents by which the 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 the Debtor (such as bylaws,
      a partnership  agreement or an operating,  limited  liability or members
      agreement).

<PAGE>

(g)   "UCC" means the Uniform  Commercial Code of the State of Delaware 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 First Priority Perfected 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, the Debtor hereby unconditionally
and irrevocably pledges, grants and hypothecates to the Secured Parties a
continuing and perfected first priority 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, the 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.

      4. Representations, Warranties, Covenants and Agreements of the Debtor.
The Debtor represents and warrants to, and covenants and agrees with, the
Secured Parties as follows:

            (a) The 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 the Debtor of this Agreement and
      the filings contemplated therein have been duly authorized by all
      necessary action on the part of the Debtor and no further action is
      required by the Debtor. This Agreement has been duly executed by the
      Debtor. This Agreement constitutes the legal, valid and binding obligation
      of the Debtor, enforceable against the 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.

            (b) The Debtor has no place of business or offices where its
      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.
      No Debtor owns any real property. Except as disclosed on Schedule A, none
      of such Collateral is in the possession of any consignee, bailee,
      warehouseman, agent or processor.

<PAGE>

            (c) Except for Permitted Liens (as defined in the Debenture) and
      except as set forth on Schedule B attached hereto, the Debtor is the sole
      owner of the Collateral (except for non-exclusive licenses granted by the
      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. 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 Secured Parties pursuant to this Agreement) covering or
      affecting any of the Collateral. So long as this Agreement shall be in
      effect, the Debtor shall not execute and shall not knowingly permit to be
      on file in any such office or agency any such financing statement or other
      document or instrument (except to the extent filed or recorded in favor of
      the Secured Parties pursuant to the terms of this Agreement).

            (d) No written claim has been received that any Collateral or
      Debtor's use of any Collateral violates the rights of any third party.
      There has been no adverse decision to the Debtor's claim of ownership
      rights in or exclusive rights to use the Collateral in any jurisdiction or
      to the 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 the Debtor, threatened before any court, judicial
      body, administrative or regulatory agency, arbitrator or other
      governmental authority.

            (e) The 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 Secured Parties 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 a valid, perfected and continuing perfected first priority lien in
      the Collateral.

            (f) This Agreement creates in favor of the Secured Parties a valid,
      first priority security interest in the Collateral, subject only to
      Permitted Liens, 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

<PAGE>

      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 Debtor, 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 Secured Parties
      hereunder.

             (g) The Debtor hereby authorizes the Secured Parties, or any of
      them, 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 them.

             (h) The execution, delivery and performance of this Agreement by
      the Debtor does not (i) violate any of the provisions of any
      Organizational Documents of the Debtor or any judgment, decree, order or
      award of any court, governmental body or arbitrator or any applicable law,
      rule or regulation applicable to the 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 the Debtor's debt or otherwise) or other
      understanding to which the Debtor is a party or by which any property or
      asset of the Debtor is bound or affected. No consent (including, without
      limitation, from stockholders or creditors of the Debtor) is required for
      the Debtor to enter into and perform its obligations hereunder.

             (i) The capital stock and other equity interests listed on Schedule
      H hereto represent all of the capital stock and other equity interests of
      the Subsidiaries, and represent all capital stock and other equity
      interests owned, directly or indirectly, by the Company. 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.

            (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.

<PAGE>

            (k) Unless the Agent (as defined in Section 18) in its sole
      discretion, consents in writing to a senior lien, the 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 Secured Parties until this Agreement and the
      Security Interest hereunder shall be terminated pursuant to Section 11
      hereof; provided, however, the Agent (as defined in Section 18), in its
      sole discretion, consents in writing to a senior lien. The Debtor hereby
      agrees to defend the same against the claims of any and all persons and
      entities. The Debtor shall safeguard and protect all Collateral for the
      account of the Secured Parties. At the request of the Secured Parties, the
      Debtor will sign and deliver to 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 Secured Parties and will pay the cost of
      filing the same in all public offices wherever filing is, or is deemed by
      the Secured Parties to be, necessary or desirable to effect the rights and
      obligations provided for herein. Without limiting the generality of the
      foregoing, the Debtor shall pay all fees, taxes and other amounts
      necessary to maintain the Collateral and the Security Interest hereunder,
      and the Debtor shall obtain and furnish to the Secured Parties 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) The Debtor will not transfer, pledge, hypothecate, encumber,
      license, sell or otherwise dispose of any of the Collateral (except for
      non-exclusive licenses granted by the Debtor in its ordinary course of
      business and sales of obsolescent inventory and of inventory by the Debtor
      in its ordinary course of business) without the prior written consent of a
      Majority in Interest.

            (m) The Debtor shall use its reasonable best efforts to keep and
      preserve its equipment, inventory and other tangible Collateral in good
      condition, repair and order (with the exception of reasonable wear and
      tear) and shall not operate or locate any such Collateral (or cause to be
      operated or located) in any area excluded from insurance coverage.

            (n) The 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. The 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

<PAGE>

      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 Debenture) exists and if the proceeds arising out of any
      claim or series of related claims do not exceed $100,000, loss payments in
      each instance will be applied by the 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 Debtor,
      provided, however, that payments received by the Debtor after an Event of
      Default occurs and is continuing or in excess of $100,000 for any
      occurrence or series of related occurrences shall be paid to the Agent
      and, if received by the Debtor, shall be held in trust for 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 as lender loss payee and additional insured shall be delivered
      to the Agent at least annually and at the time any new policy of insurance
      is issued.

            (o) The Debtor shall, within ten (10) business days of obtaining
      knowledge thereof, advise the Agent promptly, in sufficient detail, of any
      substantial change in the Collateral, and of the occurrence of any event
      which would have a material adverse effect on the value of the Collateral
      or on the Secured Parties' security interest therein.

             (p) The Debtor shall promptly execute and deliver to the Agent such
      further deeds, mortgages, assignments, security agreements, financing
      statements or other instruments, documents, certificates and assurances
      and take such further action as the Agent may from time to time request
      and may in its sole discretion deem necessary to perfect, protect or
      enforce its security interest in the Collateral including, without
      limitation, if applicable, the execution and delivery of a separate
      security agreement with respect to the Debtor's Intellectual Property
      ("Intellectual Property Security Agreement") in which the Secured Parties
      have been granted a security interest hereunder, substantially in a form
      acceptable to the Agent, which Intellectual Property Security Agreement,
      other than as stated therein, shall be subject to all of the terms and
      conditions hereof.

            (q) The Debtor shall permit the Agent and its representatives and
      agents to inspect the Collateral upon reasonable notice during regular
      business hours, and to make copies of records pertaining to the Collateral
      as may be reasonably requested by the Agent from time to time.

<PAGE>

            (r) The Debtor shall take all steps reasonably necessary to
      diligently pursue and seek to preserve, enforce and collect any rights,
      claims, causes of action and accounts receivable in respect of the
      Collateral.

            (s) The Debtor shall promptly notify the Agent in sufficient detail
      upon becoming aware of any attachment, garnishment, execution or other
      legal process levied against any Collateral and of any other information
      received by the Debtor that may materially affect the value of the
      Collateral, the Security Interest or the rights and remedies of the
      Secured Parties hereunder.

            (t) All information heretofore, herein or hereafter supplied to the
      Secured Parties by or on behalf of the Debtor with respect to the
      Collateral is accurate and complete in all material respects as of the
      date furnished.

            (u) The Debtor shall at all times preserve and keep in full force
      and effect its valid existence and good standing and any rights and
      franchises material to its business.

            (v) The Debtor will not change its name, type of organization,
      jurisdiction of organization, organizational identification number (if it
      has one), legal or corporate structure, or identity, or add any new
      fictitious name unless it provides at least 30 days prior written notice
      to the Agent of such change and, at the time of such written notification,
      the Debtor provides any financing statements or fixture filings necessary
      to perfect and continue perfected the perfected security Interest granted
      and evidenced by this Agreement.

            (w) The Debtor may not consign any of its Inventory or sell any of
      its Inventory on bill and hold, sale or return, sale on approval, or other
      conditional terms of sale without the consent of a Majority in Interest
      which shall not be unreasonably withheld, except to the extent such
      consignment or sale does not exceed 15% of the total value of all of the
      Company's finished goods in Inventory.

            (x) The Debtor may not relocate its chief executive office to a new
      location without providing 30 days prior written notification thereof to
      the Secured Parties and so long as, at the time of such written
      notification, the Debtor provides any financing statements or fixture
      filings necessary to perfect and continue perfected the perfected security
      Interest granted and evidenced by this Agreement.

             (y) The Debtor was organized and remains organized solely under the
      laws of the state set forth next to the Debtor's name in the first
      paragraph of this Agreement. Schedule D attached hereto sets forth the
      Debtor's organizational identification number or, if the Debtor does not
      have one, states that one does not exist.

<PAGE>

            (z) (i) The actual name of the Debtor is the name set forth in the
      preamble above; (ii) the Debtor has no trade names except as set forth on
      Schedule E attached hereto; (iii) the Debtor has not used any name other
      than that stated in the preamble hereto or as set forth on Schedule E for
      the preceding five years; and (iv) no entity has merged into the Debtor or
      been acquired by the Debtor within the past five years except as set forth
      on Schedule E.

            (aa) At any time and from time to time that any Collateral consists
      of instruments, certificated securities or other items that require or
      permit possession by the secured party to perfect the security interest
      created hereby, the Debtor shall deliver such Collateral to the Agent.

            (bb) The Debtor, in its capacity as issuer, hereby agrees to comply
      with any and all orders and instructions of Agent regarding the Pledged
      Interests consistent with the terms of this Agreement without the further
      consent of the Debtor as contemplated by Section 8-106 (or any successor
      section) of the UCC. Further, the Debtor agrees that it shall not enter
      into a similar agreement (or one that would confer "control" within the
      meaning of Article 8 of the UCC) with any other person or entity.

            (cc) The Debtor shall cause all tangible chattel paper constituting
      Collateral to be delivered to the Agent, or, if such delivery is not
      possible, then to cause such tangible chattel paper to contain a legend
      noting that it is subject to the security interest created by this
      Agreement. To the extent that any Collateral consists of electronic
      chattel paper, the Debtor shall cause the underlying chattel paper to be
      "marked" within the meaning of Section 9-105 of the UCC (or successor
      section thereto).

            (dd) To the extent that any Collateral consists of letter-of-credit
      rights, the Debtor shall cause the issuer of each underlying letter of
      credit to consent to an assignment of the proceeds thereof to the Secured
      Parties.

            (ee) To the extent that any Collateral is in the possession of any
      third party, the Debtor shall join with the Secured Parties in notifying
      such third party of the Secured Parties' security interest in such
      Collateral and shall use its commercially reasonable efforts to obtain an
      acknowledgement and agreement from such third party with respect to the
      Collateral, in form and substance satisfactory to the Agent.

            (ff) If the Debtor shall at any time hold or acquire a commercial
      tort claim, the Debtor shall promptly notify the Agent in a writing signed
      by the Debtor of the particulars thereof and grant to the Secured Parties
      in such writing a security interest therein and in the proceeds thereof,
      all upon the terms of this Agreement, with such writing to be in form and
      substance satisfactory to the Agent.

<PAGE>

            (gg) The Debtor shall immediately provide written notice to the
      Agent of any and all accounts which arise out of contracts with any
      governmental authority and, to the extent necessary to perfect or continue
      the perfected status of the Security Interest in such accounts and
      proceeds thereof, shall execute and deliver to the Agent an assignment of
      claims for such accounts and cooperate with the Agent in taking any other
      steps required, in their judgment, under the Federal Assignment of Claims
      Act or any similar federal, state or local statute or rule to perfect or
      continue the perfected status of the Security Interest in such accounts
      and proceeds thereof.

            (hh) In the event that the Company creates any subsidiaries after
      the date of this Agreement, the Debtor shall cause each such subsidiary of
      the Debtor to immediately become a party hereto (an "Additional Debtor"),
      by executing and delivering an Additional Debtor Joinder in substantially
      the form of Annex A attached hereto and comply with the provisions hereof
      applicable to the Debtor. Concurrent therewith, the Additional Debtor
      shall deliver replacement schedules for, or supplements to all other
      Schedules to (or referred to in) this Agreement, as applicable, which
      replacement schedules shall supersede, or supplements shall modify, the
      Schedules then in effect. The Additional Debtor shall also deliver such
      opinions of counsel, authorizing resolutions, good standing certificates,
      incumbency certificates, organizational documents, financing statements
      and other information and documentation as the Agent may reasonably
      request. Upon delivery of the foregoing to the Agent, the Additional
      Debtor shall be and become a party to this Agreement with the same rights
      and obligations as the Debtor, for all purposes hereof as fully and to the
      same extent as if it were an original signatory hereto and shall be deemed
      to have made the representations, warranties and covenants set forth
      herein as of the date of execution and delivery of such Additional Debtor
      Joinder, and all references herein to the "Debtor" shall be deemed to
      include each Additional Debtor.

            (ii) The Debtor shall vote the Pledged Securities to comply with the
      covenants and agreements set forth herein and in the Debentures.

            (jj) The Debtor shall register the pledge of the applicable Pledged
      Securities on the books of the Debtor. The Debtor shall notify each issuer
      of Pledged Securities to register the pledge of the applicable Pledged
      Securities in the name of the Secured Parties on the books of such issuer.
      Further, except with respect to certificated securities delivered to the
      Agent, the Debtor shall deliver to Agent an acknowledgement of pledge
      (which, where appropriate, shall comply with the requirements of the
      relevant UCC with respect to perfection by registration) signed by the
      issuer of the applicable Pledged Securities, which acknowledgement shall
      confirm that: (a) it has registered the pledge on its books and records;
      and (b) at any time directed by Agent during the continuation of an Event
      of Default, such issuer will transfer the record ownership of such Pledged
      Securities into the name of any designee of Agent, will take such steps as
      may be necessary to effect the transfer, and will comply with all other
      instructions of Agent regarding such Pledged Securities without the
      further consent of the Debtor.

<PAGE>

            (kk) In the event that, upon an occurrence of an Event of Default,
      the Agent shall sell all or any of the Pledged Securities to another party
      or parties (herein called the "Transferee") or shall purchase or retain
      all or any of the Pledged Securities, the Debtor shall, to the extent
      applicable: (i) deliver to Agent or the Transferee, as the case may be,
      the articles of incorporation, bylaws, minute books, stock certificate
      books, corporate seals, deeds, leases, indentures, agreements, evidences
      of indebtedness, books of account, financial records and all other
      Organizational Documents and records of the Debtor and its direct and
      indirect subsidiaries; (ii) use commercially reasonable efforts to obtain
      resignations of the persons then serving as officers and directors of the
      Debtor and its direct and indirect subsidiaries, if so requested; and
      (iii) use commercially reasonable efforts to obtain any approvals that are
      required by any governmental or regulatory body in order to permit the
      sale of the Pledged Securities to the Transferee or the purchase or
      retention of the Pledged Securities by Agent and allow the Transferee or
      Agent to continue the business of the Debtor and its direct and indirect
      subsidiaries.

             (ll) Without limiting the generality of the other obligations of
      the Debtor hereunder, the Debtor shall promptly (i) cause to be registered
      at the United States Copyright Office all of its material copyrights, (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, and (iii) give the Agent notice whenever it acquires
      (whether absolutely or by license) or creates any additional material
      Intellectual Property.

             (mm) The Debtor will from time to time, at the expense of the
      Debtor, 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 Secured Parties may reasonably request, in order to
      perfect and protect any security interest granted or purported to be
      granted hereby or to enable the Agent to exercise and enforce their rights
      and remedies hereunder and with respect to any Collateral or to otherwise
      carry out the purposes of this Agreement.

            (nn) Schedule F attached hereto lists all of the patents, patent
      applications, trademarks, trademark applications, registered copyrights,
      and domain names owned by the Debtor as of the date hereof. Schedule F
      lists all material licenses in favor of the Debtor for the use of any
      patents, trademarks, copyrights and domain names as of the date hereof.
      All material patents and trademarks of the Debtor have been duly recorded
      at the United States Patent and Trademark Office and all material
      copyrights of the Debtor have been duly recorded at the United States
      Copyright Office.

<PAGE>

            (oo) Except as set forth on Schedule G attached hereto, none of the
      account debtors or other persons or entities obligated on any of the
      Collateral is a governmental authority covered by the Federal Assignment
      of Claims Act or any similar federal, state or local statute or rule in
      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 the Debtor is subject or to which the Debtor is party.

      6. Defaults. The following events shall be "Events of Default":

            (a) The occurrence of an Event of Default (as defined in the
      Debenture) under the Debenture;

            (b) Any representation or warranty of the Debtor in this Agreement
      shall prove to have been incorrect in any material respect when made, and
      the failure of the same to be correct has a material adverse effect on
      such Debtor taken as a whole, or the ability of such Debtor to perform its
      obligations hereunder;

            (c) The failure by the Debtor to observe or perform any of its
      obligations hereunder for ten (10) business days after delivery to the
      Debtor of notice of such failure by or on behalf of a Secured Party unless
      such default is capable of cure but cannot be cured within such time frame
      and the Debtor is using commercially reasonable efforts to cure same in a
      timely fashion; or

            (d) If any provision of this Agreement shall at any time for any
      reason be declared to be null and void, or the validity or enforceability
      thereof shall be contested by the Debtor, or a proceeding shall be
      commenced by the Debtor, or by any governmental authority having
      jurisdiction over the Debtor, seeking to establish the invalidity or
      unenforceability thereof, or the Debtor shall deny that the Debtor has any
      liability or obligation purported to be created under this Agreement.

      7. Duty To Hold In Trust.

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

<PAGE>

      note, trade acceptance or other instrument evidencing an obligation to pay
      any such sum, hold the same in trust for the Secured Parties and shall
      forthwith endorse and transfer any such sums or instruments, or both, to
      the Secured Parties, pro-rata in proportion to their initial purchases of
      Debentures for application to the satisfaction of the Obligations (and if
      any Debenture is not outstanding, pro-rata in proportion to the initial
      purchases of the remaining Debentures).

            (b) If the Debtor shall become entitled to receive or shall receive
      any securities or other property (including, without limitation, shares 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
      the Debtor or any of its direct or indirect subsidiaries) in respect of
      the Pledged Securities (whether as an addition to, in substitution of, or
      in exchange for, such Pledged Securities or otherwise), the Debtor agrees
      to (i) accept the same as the agent of the Secured Parties; (ii) hold the
      same in trust on behalf of and for the benefit of the Secured Parties; and
      (iii) to deliver any and all certificates or instruments evidencing the
      same to Agent on or before the close of business on the fifth business day
      following the receipt thereof by the Debtor, in the exact form received
      together with the Necessary Endorsements, to be held by Agent subject to
      the terms of this Agreement as Collateral.

            8. Rights and Remedies Upon Default.

            (a) Upon the occurrence of any Event of Default and at any time
      thereafter, the Secured Parties, acting through any agent appointed by
      them for such purpose, 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 Secured Parties shall have the following
      rights and powers:

                  (i) The Secured Parties 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
            the Debtor shall assemble the Collateral and make it available to
            the Secured Parties at places which the Secured Parties shall
            reasonably select, whether at the Debtor's premises or elsewhere,
            and make available to the Secured Parties, without rent, all of the
            Debtor's respective premises and facilities for the purpose of the
            Secured Parties taking possession of, removing or putting the
            Collateral in saleable or disposable form.

                  (ii) Upon notice to the Debtor by Agent, all rights of the
            Debtor to exercise the voting and other consensual rights which it
            would otherwise be entitled to exercise and all rights of the Debtor
            to receive the dividends and interest which it would otherwise be

<PAGE>

            authorized to receive and retain, shall cease. Upon such notice,
            Agent shall have the right to receive 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
            owners 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 the Debtor or any of its direct or indirect
            subsidiaries.

                  (iii) The Secured Parties shall have the right to operate the
            business of the 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 Secured Parties 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 the Debtor or right of redemption of the Debtor, which are hereby
            expressly waived. Upon each such sale, lease, assignment or other
            transfer of Collateral, 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 the Debtor,
            which are hereby waived and released.

                  (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 Debtor's 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
            the 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.

<PAGE>

            (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 Debtor will only be credited
      with payments actually made by the purchaser. In addition, the 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, the 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 the
      Debtor) to use, license or sublicense following an Event of Default, any
      Intellectual Property now owned or hereafter acquired by the 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 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
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 Debtor 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, the 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.

<PAGE>

      10. Securities Law Provision. The 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. The 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. The 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. The 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 Debtor 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 Debtor 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 Debtor assumes 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) the Debtor shall remain obligated and liable under
each contract or agreement included in the Collateral to be observed or
performed by the 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 the 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.

<PAGE>

      13. Security Interest Absolute. All rights of the Secured Parties and all
obligations of the Debtor hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Agreement,
the Debentures or any agreement entered into in connection with the foregoing,
or any portion hereof or thereof; (b) any change in the time, manner or place of
payment or performance of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Debentures or any other agreement entered into in connection with the
foregoing; (c) any exchange, release or nonperfection of any of the Collateral,
or any release or amendment or waiver of or consent to departure from any other
collateral for, or any guaranty, or any other security, for all or any of the
Obligations; (d) any action by the Secured Parties to obtain, adjust, settle and
cancel in its sole discretion any insurance claims or matters made or arising in
connection with the Collateral; or (e) any other circumstance which might
otherwise constitute any legal or equitable defense available to the Debtor, or
a discharge of all or any part of the Security Interest granted hereby. Until
the Obligations shall have been paid and performed in full, the rights of the
Secured Parties shall continue even if the Obligations are barred for any
reason, including, without limitation, the running of the statute of limitations
or bankruptcy. The Debtor expressly waives presentment, protest, notice of
protest, demand, notice of nonpayment and demand for performance. In the event
that at any time any transfer of any Collateral or any payment received by the
Secured Parties hereunder shall be deemed by final order of a court of competent
jurisdiction to have been a voidable preference or fraudulent conveyance under
the bankruptcy or insolvency laws of the United States, or shall be deemed to be
otherwise due to any party other than the Secured Parties, then, in any such
event, the Debtor's obligations hereunder shall survive cancellation of this
Agreement, and shall not be discharged or satisfied by any prior payment thereof
and/or cancellation of this Agreement, but shall remain a valid and binding
obligation enforceable in accordance with the terms and provisions hereof. The
Debtor waives all right to require the Secured Parties to proceed against any
other person or entity or to apply any Collateral which the Secured Parties may
hold at any time, or to marshal assets, or to pursue any other remedy. The
Debtor waives any defense arising by reason of the application of the statute of
limitations to any obligation secured hereby.

      14. Term of Agreement. This Agreement and the Security Interest shall
terminate on the date on which all payments under the Debentures have been
indefeasibly paid in full and all other Obligations have been paid or
discharged; provided, however, that all indemnities of the Debtor 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.

<PAGE>

            (a) The Debtor authorizes the Agent, and does hereby make,
      constitute and appoint the Agent and its officers, agents, successors or
      assigns with full power of substitution, as the Debtor's true and lawful
      attorney-in-fact, with power, in the name of the various Secured Parties
      or the 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 Secured Parties; (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 Debtor, 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 deems 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 all as fully and effectually as the Debtor might or
      could do; and the 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 the Debtor is subject or to which
      the Debtor is a party. Without limiting the generality of the foregoing,
      after the occurrence and during the continuance of an Event of Default,
      the Agent 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.

             (b) On a continuing basis, the 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 Secured Parties the grant or perfection of a perfected first
      priority security interest in all the Collateral under the UCC.

<PAGE>

            (c) The Debtor hereby irrevocably appoints the Agent as the Debtor's
      attorney-in-fact, with full authority in the place and instead of the
      Debtor and in the name of the 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 the 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).

      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 Secured Parties 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 Smithfield
Fiduciary, LLC ("Smithfield" or the "Agent") to act as their 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 Smithfield may not be removed as Agent unless Smithfield shall
then hold less than $100,000 of 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 Debtor 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
      or by any other agreements, instruments or documents or by law shall be
      cumulative and may be exercised singly or concurrently.

<PAGE>

            (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 parties hereto.

            (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.

            (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. The
      Debtor agrees that all proceedings concerning the interpretations,
      enforcement and defense of the transactions contemplated by this Agreement
      and the Debenture (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.
      The 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

<PAGE>

      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 attorneys 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.

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

            (k) The Debtor shall indemnify, reimburse and hold harmless the
      Secured Parties and its respective partners, members, shareholders,
      officers, directors, employees and agents (collectively, "Indemnitees")
      from and against any and all losses, claims, liabilities, damages,
      penalties, suits, costs and expenses, of any kind or nature, (including
      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 Purchase Agreement
      (as such term is defined in the Debentures) or any other agreement,
      instrument or other document executed or delivered in connection herewith
      or therewith.

<PAGE>

            (l) Nothing in this Agreement shall be construed to subject Agent or
      any Secured Party to liability as a partner in the Debtor or any if its
      direct or indirect subsidiaries that is a partnership or as a member in
      the 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 the 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 the 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 the Debtor
      or any direct or indirect subsidiary of the Debtor or compliance with any
      provisions of any of the Organizational Documents, the Debtor hereby grant
      such consent and approval and waive any such noncompliance with the terms
      of said documents.

                                     ANNEX B
                                       to
                                    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 __________
(the "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 the 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 Debtor, 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

<PAGE>

responsible to the Debtor 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 Debtor 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 Debtor, 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
Debtor 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 Debtor, 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 Debtor 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 Debtor 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 Debtor 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.
