         4. REPRESENTATIONS AND WARRANTIES. Debtor represents and warrants to
Secured Party that:

                  (a) Purchase Agreement. Each of the representations and
         warranties of Debtor set forth in the Purchase Agreement are
         incorporated in this Security Agreement by reference and, and each such
         representation and warranty is true and correct in all material
         respects as of the date hereof as if expressly stated herein.

                  (b) Binding Obligations. This Security Agreement creates a
         legal, valid, and binding Lien in and to the Collateral in favor of
         Secured Party and enforceable against Debtor, except as may be limited
         by laws affecting creditors rights or equitable principles generally.
         For Collateral in which the Security Interest may be perfected through
         possession or "control" (within the meaning of Sections 8-106 and 9-106
         of the UCC) by Secured Party, the Security Interest constitutes a
         first-priority Lien in and to the Collateral. The creation of the
         Security Interest does not require the consent of any person that has
         not been obtained.

                  (c) Securities. The Pledged Securities are duly authorized,
         validly issued, fully paid, and non-assessable, and the transfer
         thereof is not subject to any restrictions, other than restrictions
         imposed by applicable securities and corporate laws. Debtor has good
         title to the Collateral, free and clear of all Liens and encumbrances
         thereon (except for the Security Interest created hereby), and, to the
         extent certificated has delivered to Secured Party all stock
         certificates or other instruments or documents representing or
         evidencing the securities, together with corresponding assignment or
         transfer powers duly executed in blank by Debtor, and such powers have
         been duly and validly executed and are binding and enforceable against
         Debtor in accordance with their terms, except as may be limited by laws
         affecting creditors rights or equitable principles generally; and the
         pledge of the securities in accordance with the terms hereof creates a
         valid and perfected first-priority Security Interest in the securities
         securing payment of the Obligations. Other than as set forth in this
         Security Agreement, there exist as of the date hereof, no agreement
         which could affect the transferability of any of the Pledged Shares.

                  (d) Governmental Authority. No authorization, approval, or
         other action by, and no notice to or filing with, any Governmental
         Authority is required either (i) for the pledge by Debtor of the
         Pledged Shares pursuant to this Security Agreement or for the
         execution, delivery, or performance of this Security Agreement by
         Debtor (including the filing of a financing statement under the UCC),
         or (ii) for the exercise by Secured Party of the voting or other rights

                                       4

                                                              Security Agreement

<PAGE>

         provided for in this Security Agreement or the remedies in respect of
         the Collateral pursuant to this Security Agreement (except as
         contemplated by SECTION 6 hereof).

                  (e) Liens. Debtor owns all presently existing Collateral free
         and clear of all Liens.

         5. COVENANTS. Until such time as the Obligations are paid in full,
Debtor and the Company covenant and agree with Secured Party that such party
will:

                  (a) Promptly upon knowledge thereof notify Secured Party of
         any material change in any fact or circumstances represented or
         warranted by Debtor with respect to any of the Collateral or
         Obligations and any claim, action, or proceeding affecting title to all
         or any of the Collateral or the Security Interest and, at the request
         of Secured Party, appear in and defend, at Debtor's expense, any such
         action or proceeding;

                  (b) At Debtor's or the Company's expense and Secured Party's
         request, (i) after the occurrence and continuation of a Default (as
         hereinafter defined), file or cause to be filed such applications and
         take such other actions as Secured Party may request to obtain the
         consent or approval of any Governmental Authority to Secured Party's
         rights hereunder to sell the Collateral; (ii) from time to time
         promptly execute and deliver to Secured Party all such other
         assignments, certificates, supplemental documents, and financing
         statements, and do all other acts or things as Secured Party may
         reasonably request in order to more fully create, evidence, perfect,
         continue, and preserve the priority of the Security Interest; and (iii)
         pay all filing fees in connection with any financing, continuation, or
         termination statement or other instrument with respect to the Security
         Interests.

                  (c) Impairment of Collateral. Not use any of the Collateral,
         or permit the same to be used, for any unlawful purpose, in any manner
         that is reasonably likely to adversely impair the value or usefulness
         of the Collateral, or in any manner inconsistent with the provisions or
         requirements of any policy of insurance thereon.

                  (d) Pledged Shares. Not sell, exchange, or otherwise dispose
         of, or grant any option, warrant, or other right with respect to, any
         of the Pledged Shares.

                  (e) FCC Licenses. Not sell, exchange, or otherwise dispose of,
         mortgage or encumber, or enter into any agreement to sell, exchange or
         otherwise dispose of, mortgage or encumber, or suffer to exist any
         claim, Lien or encumbrance on, or grant any option or other right with
         respect to, the FCC Licenses.

                                       5

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

                  (f) Existence. Not issue any additional securities in the
         Company, terminate the corporate existence of the Company, to be a
         party to any merger or consolidation, or to sell, lease, or dispose of
         all or substantially all of its assets and properties in a single
         transaction or a series of related transactions of the Company, except
         that Debtor may take such actions as would occur in the ordinary course
         of the Debtor's business.

                  (g) Removal of Legends. In the event Secured Party decides to
         foreclose upon or dispose of the Pledged Shares, Debtor agrees to use
         commercially reasonable efforts (subject to the requirements of
         applicable law) to assist Secured Party in expeditiously removing any
         legends on the Pledged Shares which, in Secured Party's sole judgment,
         would or could delay Secured Party's foreclosure upon or disposition of
         such Pledged Shares.

         6. DEFAULT; REMEDIES. In the event there is a default (meaning failure
to pay on a due date as set forth in each Promissory Note or within 5 business
days after written notice of such failure from the Payee) under either
Promissory Note or there exists any material breach of any representation made
by the Debtor or the Company herein, or the Debtor or the Company breaches any
covenant hereunder or if any of the following events shall occur and be
continuing for any reason whatsoever (and whether such occurrence shall be
voluntary or involuntary or come about or be effected by operation of law or
otherwise): (i) if Debtor or Company makes an assignment for the benefit of
creditors or admits in writing an inability to pay its debts generally as they
become due; or (ii) if an order, judgment or decree is entered adjudicating
Debtor or Company bankrupt or insolvent; or (iii) if Debtor or Company petitions
or applies to any tribunal for the appointment of a trustee or receiver of
Debtor or Company, or of any substantial part of the assets of Debtor or
Company, or commences any proceedings relating to Debtor or Company under any
bankruptcy, reorganization, arrangement, insolvency, readjustment of debt,
dissolution or liquidation law of any jurisdiction, whether now or hereafter in
effect; or (iv) if any such petition or application is filed, or any such
proceedings are commenced, against Debtor or Company, and Debtor or Company by
any act indicates its approval thereof, consent thereto, or acquiescence
therein, or an order is entered appointing any such trustee or receiver, or
approving the petition in any such proceedings, and such order remains unstayed
and in effect for more than 90 days; or (v) if Debtor or Company dissolves or
otherwise ceases to conduct business in the ordinary course of the Debtor's or
Company's business as generally presently conducted (any and each such event
described in this sentence being a "DEFAULT") Secured Party may exercise any and
all rights available to a secured party under the UCC, in addition to any and
all other rights afforded by this Agreement, at law, in equity, or otherwise,
including, without limitation applying by appropriate judicial proceedings for
appointment of a receiver for all or part of the Collateral (and Debtor hereby
consents to any such appointment). If a foreclosure sale on Pledged Shares is

                                       6

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

subject to SECTION 6 herein, then Secured Party will not foreclose on such
Pledged Shares unless it has given at least ten (10) days written notice to
Debtor and to the FCC, to the extent such notice is required under 47C.F.R.
22.937(f).

                  (a) Notice. To the extent that any notice of a public, private
         or other foreclosure sale is required under the UCC, such notice shall
         be sent to Debtor and to any other Person entitled to notice under the
         UCC; provided that, if any of the Collateral threatens to decline
         speedily in value or is of the type customarily sold on a recognized
         market, Secured Party may sell or otherwise dispose of the Collateral
         without notification, advertisement, or other notice of any kind.

                  (b) Sales of Pledged Shares.

                           (i) Debtor agrees that, because of the Securities Act
                  of 1933, as amended, or the rules and regulations promulgated
                  thereunder (collectively, the "SECURITIES ACT"), or any other
                  laws or regulations, and for other reasons, there may be legal
                  or practical restrictions or limitations affecting Secured
                  Party in any attempts to dispose of certain portions of the
                  Pledged Shares and for the enforcement of its rights. For
                  these reasons, Secured Party is hereby authorized by Debtor,
                  but not obligated, upon the occurrence and during the
                  continuation of a Default, to sell all or any part of the
                  Pledged Shares at private sale, subject to investment letter
                  or in any other manner which will not require the Pledged
                  Shares, or any part thereof, to be registered in accordance
                  with the Securities Act or any other laws or regulations, and
                  make a reasonable effort to sell the Pledged Shares and/or the
                  FCC Licenses at a commercially reasonable value at such
                  private sale or other distribution in the manner mentioned
                  above. Debtor understands that Secured Party may in its
                  discretion approach a limited number of potential purchasers
                  and that a sale under such circumstances may yield a lower
                  price for the Pledged Shares, or any part thereof, than would
                  otherwise be obtainable if such Collateral were either
                  afforded to a larger number or potential purchasers,
                  registered under the Securities Act, or sold in the open
                  market. Debtor agrees that any such private sale made under
                  this PARAGRAPH 6(B) shall be deemed to have been made in a
                  commercially reasonable manner, and that Secured Party has no
                  obligation to delay the sale of any Pledged Shares to permit
                  the issuer thereof to register it for public sale under any
                  applicable federal or state securities laws.

                           (ii) Secured Party is authorized, in connection with
                  any such sale, (A) to restrict the prospective bidders on or
                  purchasers of any of the Pledged Shares to a limited number of
                  sophisticated investors who will represent and agree that they
                  are purchasing for their own account for investment and not
                  with a view to the distribution or sale of any of such Pledged
                  Shares, and (B) to impose such other limitations or conditions
                  in connection with any such sale as Secured Party reasonably

                                       7

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

                  deems necessary in order to comply with applicable law. Debtor
                  covenants and agrees that it will execute and deliver such
                  documents and take such other action as Secured Party
                  reasonably deems necessary in order that any such sale may be
                  made in compliance with applicable law. Upon any such sale
                  Secured Party shall have the right to deliver, assign, and
                  transfer to the purchaser thereof the Pledged Shares so sold.
                  Each purchaser at any such sale shall hold the Pledged Shares
                  so sold absolutely free from any claim or right of Debtor of
                  whatsoever kind, including any equity or right of redemption
                  of Debtor. Debtor, to the extent permitted by applicable law,
                  hereby specifically waives all rights of redemption, stay, or
                  appraisal which it has or may have under any law now existing
                  or hereafter enacted.

                           (iii) To the extent that any notice of a public,
                  private or other foreclosure sale is required under the UCC,
                  Debtor agrees that ten (10) days' written notice from Secured
                  Party to Debtor of Secured Party's intention to make any such
                  public, private or other foreclosure sale shall constitute
                  "reasonable authenticated notification" within the meaning of
                  the UCC. Such notice shall (A) in case of a public sale, state
                  the time and place fixed for such sale, and (B) in the case of
                  a private sale, state the day after which such sale may be
                  consummated. Any public sale shall be held at such time or
                  times within ordinary business hours and at such place or
                  places as Secured Party may fix in the notice of such sale. At
                  any such sale, the Pledged Shares may be sold in one lot as an
                  entirety or in separate parcels, as Secured Party may
                  reasonably determine, and Secured Party may be the purchaser
                  thereof. Secured Party shall not be obligated to make any such
                  sale pursuant to any such notice. Secured Party may, without
                  notice or publication, adjourn any public or private sale or
                  cause the same to be adjourned from time to time by
                  announcement at the time and place fixed for the sale, and
                  such sale may be made at any time or place to which the same
                  may be so adjourned.

                           (iv) In case of any sale of all or any part of the
                  Pledged Shares on credit or for future delivery, the Pledged
                  Shares so sold may be retained by Secured Party until the
                  selling price is paid by the purchaser thereof, but Secured
                  Party shall not incur any liability in case of the failure of
                  such purchaser to take up and pay for the Pledged Shares so
                  sold and in case of any such failure, such Pledged Shares may
                  again be sold. Secured Party, instead of exercising the power
                  of sale herein conferred upon it, may proceed by a suit or
                  suits at law or in equity to foreclose the Security Interests
                  and sell the Pledged Shares, or any portion thereof, under a
                  judgment or decree of a court or courts of competent
                  jurisdiction.

                           (v) Without limiting the foregoing, or imposing upon
                  Secured Party any obligations or duties not required by
                  applicable law, Debtor acknowledges and agrees that, in
                  foreclosing upon any of the Pledged Shares, or exercising any
                  other rights or remedies provided Secured Party hereunder or
                  under applicable law, Secured Party may, but, except to the
                  extent required by law, shall not be required to: (A) qualify
                  or restrict prospective purchasers of the Pledged Shares by
                  requiring evidence of sophistication or creditworthiness and,
                  to the extent required consents are necessary as contemplated
                  by SECTION 6 hereof, evidence of capability to obtain such
                  required consents, and requiring the execution and delivery of
                  confidentiality agreements or other documents and agreements
                  as a condition to such prospective purchasers' receipt of
                  information regarding the Pledged Shares or participation in
                  any public or private foreclosure sale process, (B) provide to
                  prospective purchasers business and financial information
                  regarding Debtor available in the files of Secured Party at
                  the time of commencing the foreclosure process, without the
                  requirement that Secured Party obtain, or seek to obtain, any
                  updated business or financial information or verify, or
                  certify to prospective purchasers, the accuracy of any such
                  business or financial information, or (C) offer for sale and
                  sell the Pledged Shares with, or without, first employing an
                  appraiser, investment banker, or broker with respect to the
                  evaluation of the Pledged Shares, the solicitation of
                  purchasers for Pledged Shares, or the manner of sale of
                  Pledged Shares.

                  (c) Application of Proceeds. Secured Party shall apply the
         proceeds of any sale or other disposition of the Collateral under this
         PARAGRAPH 6 in the following order: first, to the payment of all
         expenses incurred in retaking, holding, and preparing any of the
         Collateral for sale(s) or other disposition, in arranging for such
         sale(s) or other disposition, and in actually selling or disposing of
         the same (all of which are part of the Obligations); second, toward
         payment of the balance of the Obligations. Any surplus remaining shall
         be delivered to Debtor or as a court of competent jurisdiction may
         direct. If the proceeds are insufficient to pay the Obligations in
         full, Debtor shall remain liable for any deficiency.

                                            Execution Copy - 11/25/2003 11:27 AM

         7. OTHER RIGHTS OF SECURED PARTY.

                  (a) Performance. If Debtor fails to keep the Collateral in
         good standing and condition, as required in this Security Agreement, or
         fails to preserve the priority of the Security Interest in any of the
         Collateral, or otherwise fails to perform any of the Obligations, then
         Secured Party may, at its option, but without being required to do so,
         take all other action which Debtor is required, but has failed or
         refused, to take. Any sum which may be expended or paid by Secured
         Party under this subparagraph (including, without limitation, court
         costs and reasonable attorneys' fees) shall bear interest from the
         dates of expenditure or payment at the interest rate set for a default
         under the Promissory Notes until paid and, together with such interest,
         shall be payable by Debtor to Secured Party upon demand and shall be
         part of the Obligations.

                  (b) Record Ownership of Securities. If a Default exists,
         Secured Party at any time may have any Collateral that is Pledged
         Shares and that is in the possession of Secured Party, or its nominee
         or nominees, registered in its name, or in the name of its nominee or
         nominees, as pledgee; and, as to any Pledged Shares so registered,
         Debtor shall execute and deliver (or cause to be executed and
         delivered) to Secured Party all such proxies, powers of attorney,
         dividend coupons or orders, and other documents as Secured Party may
         reasonably request for the purpose of enabling Secured Party to
         exercise the voting rights and powers which it is entitled to exercise
         under this Security Agreement or to receive the dividends and other
         payments in respect of such Collateral that is Pledged Shares which it
         is authorized to receive and retain under this Security Agreement.

                  (c) Voting of Securities. As long no Default exists, Debtor is
         entitled to exercise all voting rights pertaining to any Collateral
         that is Pledged Shares. If a Default exists and is continuing, and if
         Secured Party elects to exercise such right by delivering written
         notice of such election to Debtor, then the right to vote any
         Collateral that is Pledged Shares shall be vested exclusively in
         Secured Party. To this end, Debtor hereby irrevocably constitutes and
         appoints Secured Party the proxy and attorney-in-fact of Debtor, with
         full power of substitution, to vote, and to act with respect to, any
         and all Collateral that is Pledged Shares standing in the name of
         Debtor or with respect to which Debtor is entitled to vote and act,
         subject to the understanding that such proxy may not be exercised
         unless a Default exists and is continuing. The proxy herein granted is
         coupled with an interest, is irrevocable, and shall continue until the
         Obligations has been paid and performed in full.

                  (d) Certain Proceeds. Any and all stock dividends or
         distributions in property made on or in respect of any Pledged Shares,
         and any proceeds of any Pledged Shares, whether such dividends,

                                       10

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

         distributions, or proceeds result from a subdivision, combination, or
         reclassification of the outstanding capital stock of any issuer thereof
         or as a result of any merger, consolidation, acquisition, or other
         exchange of assets to which any issuer may be a party, or otherwise,
         shall be part of the Collateral hereunder, shall, if received by
         Debtor, be held in trust for the benefit of Secured Party, and shall
         forthwith be delivered to Secured Party (accompanied by proper
         instruments of assignment and/or stock and/or bond powers executed by
         Debtor in accordance with Secured Party's instructions) to be held
         subject to the terms of this Security Agreement. Any cash proceeds of
         Collateral which come into the possession of Secured Party (including,
         without limitation, insurance proceeds) may, at Secured Party's option,
         be applied in whole or in part to the Obligations (to the extent then
         due), be released in whole or in part to or on the written instructions
         of Debtor for any general or specific purpose, or be retained in whole
         or in part by Secured Party as additional Collateral.

                  (e) Use and Operation of Collateral. Should any Collateral
         come into the possession of Secured Party, Secured Party may use or
         operate such Collateral for the purpose of preserving it or its value
         pursuant to the order of a court of appropriate jurisdiction or in
         accordance with any other rights held by Secured Party in respect of
         such Collateral. Debtor covenants to promptly reimburse and pay to
         Secured Party, at Secured Party's request, the amount of all reasonable
         expenses (including, without limitation, the cost of any insurance and
         payment of taxes or other charges) incurred by Secured Party in
         connection with its custody and preservation of Collateral, and all
         such expenses, costs, taxes, and other charges shall bear interest at
         the default rate until repaid and, together with such interest, shall
         be payable by Debtor to Secured Party upon demand and shall become part
         of the Obligations. However, the risk of accidental loss or damage to,
         or diminution in value of, Collateral is on Debtor, and Secured Party
         shall have no liability whatever for failure to obtain or maintain
         insurance, nor to determine whether any insurance ever in force is
         adequate as to amount or as to the risks insured. With respect to
         Collateral that is in the possession of Secured Party, Secured Party
         shall have no duty to fix or preserve rights against prior parties to
         such Collateral and shall never be liable for any failure to use
         diligence to collect any amount payable in respect of such Collateral,
         but shall be liable only to account to Debtor for what it may actually
         collect or receive thereon. The provisions of this subparagraph are
         applicable whether or not a Default exists.

                  (f) Power of Attorney. For use following and during the
         continuation of a Default, Debtor hereby irrevocably constitutes and
         appoints Secured Party as Debtor's attorney-in-fact, with full
         irrevocable power and authority in the place and stead of Debtor and in
         the name of Debtor, Secured Party or otherwise, from time to time in

                                       11

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

         Secured Party's discretion, for the sole purpose of carrying out the
         terms of this Security Agreement, enforcing Secured Party's rights
         under this Security Agreement, and, to the extent permitted by
         applicable law, to take any action and to execute any document and
         instrument which Secured Party may deem necessary or advisable to
         execute on behalf of Debtor any continuation statement with respect to
         the Security Interests created hereby, and to do any and all acts and
         things to protect, preserve and (following a Default) foreclose upon
         the Collateral, including, without limitation, the protection and
         prosecution of all rights included in the Collateral.

                  (G) INDEMNIFICATION. DEBTOR HEREBY ASSUMES ALL LIABILITY FOR
         THE COLLATERAL AND FOR THE SECURITY INTEREST ARISING AS A RESULT OF OR
         IN CONNECTION WITH, THE TRANSACTIONS CONTEMPLATED HEREIN. DEBTOR AGREES
         TO INDEMNIFY, SAVE, AND HOLD SECURED PARTY HARMLESS FROM AND AGAINST,
         AND COVENANTS TO DEFEND SECURED PARTY AGAINST, ANY AND ALL LOSSES,
         DAMAGES, CLAIMS, COSTS, PENALTIES, LIABILITIES, AND EXPENSES
         (COLLECTIVELY, "CLAIMS"), INCLUDING, WITHOUT LIMITATION, COURT COSTS
         AND REASONABLE ATTORNEYS' FEES, AND ANY OF THE FOREGOING ARISING FROM
         SECURED PARTY'S ENFORCEMENT OF THIS SECURITY AGREEMENT UPON A DEFAULT
         BY DEBTOR OR THE COMPANY. WITHOUT LIMITING THE FOREGOING, AND
         NOTWITHSTANDING THE EXISTENCE OF A DEFAULT, DEBTOR AND COMPANY
         EXPRESSLY RELEASE AND HOLD HARMLESS SECURED PARTY FROM ANY OBLIGATIONS
         OR RESPONSIBILITIES WITH RESPECT TO SECURED PARTY'S REASONABLE STEPS
         TAKEN TO ENSURE THE PRESERVATION OF THE FCC LICENSES, INCLUDING ANY
         OBLIGATION OR RESPONSIBLITY RELATING TO COMPLIANCE WITH ANY REGULATION
         OR REQUIREMENT OF THE FCC.

         8. ACKNOWLEDGMENT OF REGULATORY CONSIDERATIONS

         If any consents, authority, or approval of the FCC or any applicable
PUC (collectively, "REQUIRED CONSENTS") is required in connection with the
exercise by Secured Party of any rights granted, or action to be taken,
hereunder with respect to the Collateral, then the following provisions shall
apply:

                  (a) FCC Approval. Notwithstanding anything to the contrary
         contained in this Security Agreement, Secured Party will not consummate
         any foreclosure sale or take any other actions pursuant to this
         Security Agreement which would constitute a transfer of control or an
         assignment of an FCC License if such transfer of control or assignment
         would require under then-existing law (including the written rules and
         regulations promulgated by the FCC or any other applicable PUC with

                                       12

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

         jurisdiction) any consents, without first obtaining such consents. To
         the fullest extent permitted by applicable laws, Secured Party
         nevertheless may, without limiting other rights and remedies available
         to it by applicable laws or agreement, give notice of a proposed
         foreclosure sale, prepare for such sale, and conduct such sale, subject
         to a requirement (to the extent required by applicable laws) that such
         sale will not be consummated until Required Consents are obtained.
         Debtor further acknowledges that any such approval process would
         substantially delay the consummation of a foreclosure sale,
         significantly restrict the number of possible bidders at any such
         foreclosure sale, and reduce the price which would be bid or paid in
         connection with any such foreclosure sale; and notwithstanding the
         foregoing, conduct of such a foreclosure, subject to such approval
         procedure, shall be commercially reasonable and Secured Party shall
         have no obligation or liability to Debtor in connection therewith.

                  (b) Actions by Debtor. Debtor agrees to take, and cause to be
         taken, any action which Secured Party may reasonably request in order
         to obtain and enjoy the full rights and benefits granted to Secured
         Party by this Security Agreement and any other instruments or
         agreements executed pursuant hereto, including, without limitation,
         Debtor, at its sole cost and expense, agrees to use its best efforts to
         secure the Required Consents and to cooperate with Secured Party in any
         action commenced by Secured Party to secure such consent. Upon the
         occurrence and during the continuation of a Default, Debtor shall
         promptly prepare and execute or cause the preparation and execution
         (including the preparation and execution by Communications) of all
         applications, certificates, instruments, and other documents and papers
         that may be required to file in order to obtain any required consents,
         and if Debtor fails or refuses to prepare or execute (or cause
         preparation and execution of) such documents, then, on the order of any
         court of competent jurisdiction, the Clerk of the Court with
         jurisdiction may prepare and execute such documents on behalf of
         Debtor. Debtor further recognizes that a violation of this covenant
         would result in irreparable harm to Secured Party for which monetary
         damages are not readily ascertainable and which might not fully
         compensate Secured Party. Therefore, in addition to any other remedy
         which may be available to Secured Party, at law or in equity, Secured
         Party shall have the remedy of specific performance of the provisions
         of this subsection.

         9. MISCELLANEOUS.

                  (a) Continuing Security Interest. This Security Agreement
         creates a continuing security interest in the Collateral and shall (i)
         remain in full force and effect until the termination of the
         Obligations of Secured Party; (ii) be binding upon Debtor, its
         successors, and assigns; and (iii) inure to the benefit of and be

                                       13

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM
<PAGE>

         enforceable by the Secured Party, and its respective successors,
         transferees, and assigns. Without limiting the generality of the
         foregoing CLAUSE (III), the Secured Party may assign or otherwise
         transfer any of its respective rights under this Security Agreement to
         any other Person who acquires an interest in either Promissory Note,
         and such Person shall thereupon become vested with all the rights and
         benefits in respect thereof granted herein or otherwise to the Secured
         Party to the extent of such assignment or transfer. Upon payment in
         full of the Obligations, Debtor shall be entitled to the return, upon
         its request and at its expense, of such of the Collateral as shall not
         have been sold or otherwise applied pursuant to the terms hereof.

                  (b) Actions Not Releases. The Security Interest and Debtor's
         obligations and Secured Party's rights hereunder shall not be released,
         diminished, impaired, or adversely affected by the occurrence of any
         one or more of the following events: (i) the taking or accepting of any
         other security or assurance for any or all of the Obligations; (ii) any
         release, surrender, exchange, subordination, or loss of any security or
         assurance at any time existing in connection with any or all of the
         Obligations; (iii) the insolvency, bankruptcy, or lack of corporate or
         trust power of any party at any time liable for the payment of any or
         all of the Obligations, whether now existing or hereafter occurring;
         (iv) any renewal, extension, or rearrangement of the payment of any or
         all of the Obligations, either with or without notice to or consent of
         Debtor, or any adjustment, indulgence, forbearance, or compromise that
         may be granted or given by Secured Party to Debtor; (v) any neglect,
         delay, omission, failure, or refusal of Secured Party to take or
         prosecute any action in connection with any other agreement, document,
         guaranty, or instrument evidencing, securing, or assuring the payment
         of all or any of the Obligations; (vi) any failure of Secured Party to
         notify Debtor of any renewal, extension, or assignment of the
         Obligations or any part thereof, or the release of any security, or of
         any other action taken or refrained from being taken by Secured Party
         against Debtor or any new agreement between Secured Party and Debtor,
         it being understood that Secured Party shall not be required to give
         Debtor any notice of any kind under any circumstances whatsoever with
         respect to or in connection with the Obligations, including, without
         limitation, notice of acceptance of this Security Agreement or any
         Collateral ever delivered to or for the account of Secured Party
         hereunder; (vii) the illegality, invalidity, or unenforceability of all
         or any part of the Obligations against any party obligated with respect
         thereto by reason of the fact that the Obligations, or the interest
         paid or payable with respect thereto, exceeds the amount permitted by
         law, the act of creating the Obligations, or any part thereof, is ultra
         vires, or the officers, partners, or trustees creating same acted in
         excess of their authority, or for any other reason; or (viii) if any

                  (e) Multiple Counterparts. This Security Agreement has been
         executed in a number of identical counterparts, each of which shall be
         deemed an original for all purposes and all of which constitute,
         collectively, one agreement; but, in making proof of this Security
         Agreement, it shall not be necessary to produce or account for more
         than one such counterpart.

                  (f) Parties Bound; Assignment. This Security Agreement shall
         be binding on Debtor and the Company's and Debtor and the Company's

         obligations hereunder.

                  (g) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED AS TO ITS
         VALIDITY, INTERPRETATION, AND EFFECT SOLELY IN ACCORDANCE WITH THE LAWS
         OF THE STATE OF FLORIDA, EXCEPT IF THE VALIDITY OR PERFECTION OF THE
         SECURITY INTERESTS HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY
         PARTICULAR COLLATERAL, ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER
         THAN THE STATE OF FLORIDA. UNLESS THE CONTEXT OTHERWISE REQUIRES, ALL
         TERMS USED HEREIN WHICH ARE DEFINED IN THE UNIFORM COMMERCIAL CODE AS
         ENACTED IN THE STATE OF FLORIDA SHALL HAVE THE MEANINGS THEREIN STATED.

                  (h) Jurisdiction and Venue; Service of Process; Waiver of
         Trial by Jury; Attorneys' Fees. If any dispute or controversy shall
         arise between any of the parties hereto, such dispute or controversy

                                                              Security Agreement
                                            Execution Copy - 11/25/2003 11:27 AM

         may only be brought for resolution solely in the federal and/or state
         courts located in Broward County, Florida. Each of the parties hereto
         hereby consent solely to the jurisdiction and venue of such courts, and
         agree that they shall not contest or challenge the jurisdiction or
         venue of such courts. Each of the parties hereto agrees that service of
         any process, summons, notice or document, by U.S. registered or
         certified mail, to its address set forth in or as provided in Section
         8.08 of the Purchase Agreement shall be effective service of process
         for any action, suit or proceeding brought against it in any such
         court. In recognition of the fact that the issues which would arise
         under or relating to this Security Agreement, are of such a complex
         nature that they could not be properly be tried before a jury, each of
         the parties hereto waives trial by jury. The prevailing party in any
         action and/or proceeding shall be entitled to recover its reasonable
         attorneys' fees and costs from the other party/parties to such action,
         suit or proceeding.

                  (i) Return of Collateral. Upon timely payment in full to
         Secured Party of the Obligations, Secured Party shall immediately
         return the Collateral unencumbered to the Company and the Debtor.
