have the right, at any time during normal business hours, upon reasonable prior
notice, to visit and inspect the properties of the Company and its corporate,
financial and operating records, and make abstracts therefrom, and to discuss
the Company's affairs, finances and accounts with its directors, officers and
independent public accountants.

Subsidiaries shall fail to observe or perform any other covenant, obligation,
condition or agreement contained in this Note or the other Transaction Documents
(other than those specified in Sections 7(a) and 7(b)) and (i) such failure
shall continue for fifteen (15) days, or (ii) if such failure does not result
from the payment of money or the failure to pay money and is not curable within

days or (B) the Company or its Subsidiary shall not have commenced a cure in a
manner reasonably satisfactory to the Holder within the initial fifteen (15) day
period; or

             (d) Representations and Warranties. Any representation, warranty,
certificate, or other statement (financial or otherwise) made or furnished by or
on behalf of the Company to the Holder in writing in connection with this Note

continue beyond any period of grace provided with respect thereto, or (B)
default in the observance or performance of any other agreement, term or
condition contained in any such bond, debenture, note or other evidence of
Indebtedness, and (ii) the effect of such failure or default is to cause, or
permit the holder or holders thereof to cause, Indebtedness in an aggregate
amount of Two Hundred Fifty Thousand Dollars ($250,000) or more to become due
prior to its stated date of maturity, unless such acceleration shall have been
rescinded and such failure to pay cured within thirty (30) days from the date of

property thereof, or an involuntary case or other proceedings seeking

of its Subsidiaries or the debts thereof under any bankruptcy, insolvency or
other similar law now or hereafter in effect shall be commenced and an order for
relief entered or such proceeding shall not be dismissed or discharged within
sixty (60) days of commencement; or

             (h) Judgments. A final judgment or order for the payment of money
in excess of Two Hundred Fifty Thousand Dollars ($250,000) (exclusive of amounts
covered by insurance issued by an insurer not an affiliate of Company) shall be
rendered against the Company or any of its Subsidiaries and the same shall
remain undischarged for a period of thirty (30) days during which execution
shall not be effectively stayed, or any judgment, writ, assessment, warrant of
attachment, or execution or similar process shall be issued or levied against a
substantial part of the property of the Company or any of its


                                     -11-
   12
Subsidiaries and such judgment, writ, or similar process shall not be released,
stayed, vacated or otherwise dismissed within thirty (30) days after issue or
levy; or

             (i) Transaction Documents. Any Transaction Document (other than the
Merger Agreement) or any material term thereof shall cease to be, or be asserted
by the Company not to be, a legal, valid and binding obligation of Company
enforceable in accordance with its terms or if the Liens of the Holder in any of
the assets of Company or its Subsidiaries shall cease to be or shall not be
valid and perfected Liens or the Company or any Subsidiary shall assert that
such Liens are not valid and perfected Liens.

          8. RIGHTS OF HOLDER UPON DEFAULT. Upon the occurrence or existence of
any Event of Default (other than an Event of Default referred to in
Sections 7(f) and 7(g)) and at any time thereafter during the continuance of
such Event of Default, the Holder may, by written notice to the Company, declare
all outstanding Obligations payable by the Company hereunder to be immediately
due and payable without presentment, demand, protest or any other notice of any
kind, all of which are hereby expressly waived, anything contained herein or in
the other Transaction Documents to the contrary notwithstanding. Upon the
occurrence or existence of any Event of Default described in Sections 7(f) and
7(g), immediately and without notice, all outstanding Obligations payable by
Company hereunder shall automatically become immediately due and payable,
without presentment, demand, protest or any other notice of any kind, all of
which are hereby expressly waived, anything contained herein or in the other
Transaction Documents to the contrary notwithstanding. In addition to the
foregoing remedies, upon the occurrence or existence of any Event of Default,
the Holder may exercise any other right, power or remedy granted to it by the
Transaction Documents or otherwise permitted to it by law, either by suit in
equity or by action at law, or both.

          9. SUBORDINATION. The indebtedness evidenced by this Note is hereby
expressly subordinated, to the extent and in the manner hereinafter set forth,
in right of payment to the prior payment in full of the Senior Indebtedness.

             (a) Insolvency Proceedings. If there shall occur any receivership,
insolvency, assignment for the benefit of creditors, bankruptcy, reorganization,
or arrangements with creditors (whether or not pursuant to bankruptcy or other
insolvency laws), sale of all or substantially all of the assets, dissolution,
liquidation, or any other marshaling of the assets and liabilities of the
Company, (i) no amount shall be paid by the Company in respect of the principal
of, interest on or other amounts due with respect to this Note at the time
outstanding, unless and until the principal of and interest on the Senior
Indebtedness then outstanding shall be paid in full, and (ii) no claim or proof
of claim shall be filed with the Company by or on behalf of Holder of this Note
which shall assert any right to receive any payments in respect of the principal
of and interest on this Note except subject to the payment in full of the
principal of and interest on all of the Senior Indebtedness then outstanding.

             (b) Default on Senior Indebtedness. If there shall occur an event
of default which has been declared in writing with respect to any Senior
Indebtedness, as defined therein, or in the instrument under which it is
outstanding, permitting the holder to accelerate the maturity thereof and the
Holder shall have received written notice thereof from the holder of such Senior
Indebtedness, then, unless and until 


                                      -12-
   13
such event of default shall have been cured or waived or shall have ceased to
exist, or all Senior Indebtedness shall have been paid in full, no payment shall
be made in respect of the principal of or interest on this Note, unless within
one hundred eighty (180) days after the happening of such event of default, the
maturity of such Senior Indebtedness shall not have been accelerated. Not more
than one notice may be given to Holder pursuant to the terms of this Section
9(b) during any 360 day period.

             (c) Further Assurances. By acceptance of this Note, the Holder
agrees to execute and deliver customary forms of subordination agreement
requested from time to time by holders of Senior Indebtedness, and as a
condition to the Holder's rights hereunder, the Company may require that the
Holder execute such forms of subordination agreement; provided that such forms
shall not impose on the Holder terms less favorable than those provided herein
and in the Security Agreement.

             (d) Other Indebtedness. No indebtedness which does not constitute
Senior Indebtedness shall be senior in any respect to the indebtedness
represented by this Note.

             (e) Subrogation. Subject to the payment in full of all Senior
Indebtedness, the Holder shall be subrogated to the rights of the holder(s) of
such Senior Indebtedness (to the extent of the payments or distributions made to
the holder(s) of such Senior Indebtedness pursuant to the provisions of this
Section 9) to receive payments and distributions of assets of the Company
applicable to the Senior Indebtedness. No such payments or distributions
applicable to the Senior Indebtedness shall, as between the Company and its
creditors, other than the holders of Senior Indebtedness and the Holder, be
deemed to be a payment by the Company to or on account of this Note; and for
purposes of such subrogation, no payments or distributions to the holders of
Senior Indebtedness to which the Holder would be entitled except for the
provisions of this Section 9 shall, as between the Company and its creditors,
other than the holders of Senior Indebtedness and the Holder, be deemed to be a
payment by the Company to or on account of the Senior Indebtedness.

             (f) No Impairment. Subject to the rights, if any, of the holders of
Senior Indebtedness under this Section 9 to receive cash, securities or other
properties otherwise payable or deliverable to the Holder, nothing contained in
this Section 9 shall impair, as between the Company and the Holder, the
obligation of the Company, subject to the terms and conditions hereof, to pay to
the Holder the principal hereof and interest hereon as and when the same become
due and payable, or shall prevent the Holder, upon default hereunder, from
exercising all rights, powers and remedies otherwise provided herein or by
applicable law.

             (g) Lien Subordination. Any Lien of the Holder, whether now or
hereafter existing in connection with the amounts due under this Note, on any
assets or property of the Company or any proceeds or revenues therefrom which
the Holder may have at any time as security for any amounts due and obligations
under this Note shall be subordinate to all Liens now or hereafter granted to a
holder of Senior Indebtedness by Company or by law, notwithstanding the date,
order or method of attachment or perfection of any such Lien or the provisions
of any applicable law.

             (h) Reliance of Holders of Senior Indebtedness. The Holder, by its
acceptance hereof, shall be deemed to acknowledge and agree that the foregoing
subordination provisions are, and are 

                                      -13-
   14
intended to be, an inducement to and a consideration of each holder of Senior
Indebtedness, whether such Senior Indebtedness was created or acquired before or
after the creation of the indebtedness evidenced by this Note, and each such
holder of Senior Indebtedness shall be deemed conclusively to have relied on
such subordination provisions in acquiring and holding, or in continuing to
hold, such Senior Indebtedness.

          10. CONVERSION.

             (a) Conversion by Holder. In the event that the Merger Agreement is
terminated pursuant to Section 8(a), 8(b) or 8(d) (i) through 8(d)(iv) thereof
or upon the occurrence of an Event of Default hereunder, then from and after
such date, the Holder shall have the right, at such Holder's option, at any time
prior to payment in full of the principal balance of this Note, to convert this
Note, in accordance with the provisions of Section 10(c) hereof, in whole or in
part, into fully paid and nonassessable shares of Series A Preferred, provided
that the Holder shall provide at least thirty (30) days notice to the Company of
Holder's election to convert this Note into shares of Series A Preferred upon
the occurrence of an Event of Default. The number of shares of Series A
Preferred into which this Note may be converted shall be determined by dividing
the aggregate amount of this Note to be converted by the Conversion Price (as
defined below) in effect at the time of such conversion. The initial "Conversion
Price" shall be equal to $1.00 per share. The Conversion Price shall be subject
to adjustment from time to time pursuant to Section 12 hereof and the terms of
the Company's Certificate.

             (b) Conversion by the Company. In the event that the Merger
Agreement is terminated pursuant to Section 8(c), 8(d)(v) or 8(d)(vi) thereof,
the Company shall have the right, at the Company's option, to convert this Note,
in accordance with the provisions of Section 10(c) hereof, in whole or in part,
into fully paid and nonassessable shares of Series A Preferred. The number of
shares of Series A Preferred into which this Note may be converted shall be
determined by dividing the aggregate amount of this Note to be converted by the
Conversion Price in effect at the time of such conversion.

             (c) Conversion Procedure.

                 (i) Conversion Pursuant to Section 10(a). Before the Holder
shall be entitled to convert this Note into shares of Series A Preferred, it
shall surrender this Note, duly endorsed, at the office of the Company and shall
give written notice, postage prepaid, to the Company at its principal corporate
office, of the election to convert the same pursuant to Section 10(a), and shall
state therein the amount of the unpaid principal amount of this Note to be
converted and the name or names in which the certificate or certificates for
shares of Series A Preferred are to be issued. The Company shall, as soon as
practicable thereafter (but in any event within ten (10) days thereafter), issue
and deliver to the Holder of this Note a certificate or certificates for the
number of shares of Series A Preferred to which the Holder shall be entitled
upon conversion (bearing such legends as are required by applicable state and
federal securities laws), together with a replacement Note (if any principal
amount is not converted) and any other securities and property to which the
Holder is entitled upon such conversion under the terms of this Note, including
a check payable to Holder for any cash amounts payable as described in
Section 10(d). The conversion shall be deemed to have been made immediately
prior to the close of business on the date 

                                      -14-
   15
of the surrender of this Note, and the Person or Persons entitled to receive the
shares of Series A Preferred upon such conversion shall be treated for all
purposes as the record holder or holders of such shares of Series A Preferred as
of such date.

                 (ii) Conversion Pursuant to Section 10(b). If this Note is
converted by the Company pursuant to Section 10(b), written notice shall be
delivered to the Holder notifying the Holder of the conversion to be effected,
specifying the Conversion Price, the principal amount of the Note to be
converted, the date on which such conversion is expected to occur and calling
upon such Holder to surrender to Company, in the manner and at the place
designated, the Note. Upon such conversion of this Note, the Holder shall
surrender this Note, duly endorsed, at the principal office of Company. At its
expense, the Company shall, as soon as practicable thereafter (but in any event
within ten (10) days thereafter), issue and deliver to such Holder a certificate
or certificates for the number of shares to which Holder shall be entitled upon
such conversion (bearing such legends as are required by applicable state and
federal securities laws), together with any other securities and property to
which the Holder is entitled upon such conversion under the terms of this Note,
including a check payable to the Holder for any cash amounts payable as
described in Section 10(d). Any conversion of this Note pursuant to
Section 10(b) shall be deemed to have been made immediately prior to the closing
of the issuance and sale of shares as described in Section 10(b) and on and
after such date the Person entitled to receive the shares issuable upon such
conversion shall be treated for all purpose as the record Holder of such shares
as of such date.

             (d) Fractional Shares; Interest; Effect of Conversion. No
fractional shares shall be issued upon conversion of this Note. In lieu of the
Company issuing any fractional shares to the Holder upon the conversion of this
Note, the Company shall pay to the Holder an amount equal to the product
obtained by multiplying the Conversion Price by the fraction of a share not
issued pursuant to the previous sentence. In addition, the Company shall pay to
the Holder any interest accrued on the amount converted and on the amount to be
paid to the Company pursuant to the previous sentence. Upon conversion of this
Note in full and the payment of the amounts specified in this Section 10(d), the
Company shall be forever released from all its obligations and liabilities under
this Note.

          11. ISSUANCES OF WARRANTS. In the event that the Holder elects to
convert all or any portion of this Note into shares of Series A Preferred
pursuant to Section 10(a) hereof, or in the event the Company elects to convert
all or any portion of this Note into shares of Series A Preferred pursuant to
Section 10(b) hereof the Company hereby agrees to issue to the Holder warrants
to purchase shares of Series A Preferred (the "Warrant") as set forth below:

             (a) No Warrant shall be issued if the principal amount of this Note
to be converted together with any principal amount of this Note previously
converted is less than $5,000,001.

             (b) If the principal amount of this Note to be converted together
with any principal amount of this Note previously converted is more than
$5,000,000, the Company shall issue to the Holder concurrent with the issuance
of the shares of Series A Preferred to be issued upon such conversion, a Warrant
to purchase up to 7,500,000 shares of Series A Preferred. The number of shares
subject to the first Warrant to be issued shall be determined by multiplying
7,500,000 times a fraction, the numerator 


                                      -15-
   16
of which is the amount by which the aggregate principal amount to be converted
exceeds $5,000,000 and the denominator of which is $20,000,000. The number of
shares subject to any subsequent Warrant to be issued shall be determined by
multiplying 7,500,000 times a fraction, the numerator of which is the aggregate
principal amount to be converted and the denominator of which is $20,000,000.

             (c) Each Warrant to be issued by the Company pursuant to this
Section 11 shall have an exercise price of $2.00 per share, a term of five (5)
years and such other terms as are set forth in the form of Warrant attached
hereto as Exhibit A.

             (d) The shares of Series A Preferred issuable upon the exercise of
any Warrants issued pursuant to this Section 11 shall be entitled to
registration rights which are pari passu with the registration rights held by
the holders of the Company's Series A Preferred Stock.

          12. CONVERSION PRICE ADJUSTMENTS.

             (a) Adjustments for Stock Splits and Subdivisions. In the event the
Company should at any time or from time to time after the date of issuance
hereof fix a record date for the effectuation of a split or subdivision of the
outstanding shares of Series A Preferred or the determination of holders of
Series A Preferred entitled to receive a dividend or other distribution payable
in additional shares of Series A Preferred or other securities or rights
convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Series A Preferred (hereinafter referred to as
"Series A Preferred Equivalents") without payment of any consideration by such
holder for the additional shares of Series A Preferred or the Series A Preferred
Equivalents (including the additional shares of Series A Preferred issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such dividend distribution, split or subdivision if no record date is fixed),
the Conversion Price of this Note shall be appropriately decreased so that the
number of shares of Series A Preferred issuable upon conversion of this Note
shall be increased in proportion to such increase of outstanding shares.

             (b) Adjustments for Reverse Stock Splits. If the number of shares
of Series A Preferred outstanding at any time after the date hereof is decreased
by a combination of the outstanding shares of Series A Preferred, then,
following the record date of such combination, the Conversion Price for this
Note shall be appropriately increased so that the number of shares of Series A
Preferred issuable on conversion hereof shall be decreased in proportion to such
decrease in outstanding shares.

             (c) Conversion or Redemption of Series A Preferred Stock. Should
all of Company's Series A Preferred Stock be, or if outstanding would be, at any
time prior to full payment of this Note, redeemed or converted into shares of
Company's Common Stock in accordance with the Certificate, then this Note shall
immediately become convertible into that number of shares of Company's Common
Stock equal to the number of shares of the Common Stock that would have been
received if this Note had been converted in full and the Series A Preferred
Stock received thereupon had been simultaneously converted immediately prior to
such event, and the Conversion Price shall be immediately adjusted to equal the
quotient obtained by dividing (x) the aggregate Conversion Price of the maximum
number of shares of Series A Preferred Stock into which this Note was
convertible immediately prior to such conversion or 

                                      -16-
   17
redemption, by (y) the number of shares of Common Stock for which this Note is
convertible immediately after such conversion or redemption.

             (d) Notices of Record Date, etc. In the event of:

                 (i) Any taking by the Company of a record of the holders of any
class of securities of the Company for the purpose of determining the holders
thereof who are entitled to receive any dividend (other than a cash dividend
payable out of earned surplus at the same rate as that of the last such cash
dividend theretofore paid) or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right; or

                (ii) Any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
transfer of all or substantially all of the assets of the Company to any other
Person or any consolidation or merger involving the Company; or

               (iii) Any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, the Company will mail to Holder of this Note at least
ten (10) days prior to the earliest date specified therein, a notice specifying
(A) the date on which any such record is to be taken for the purpose of such
dividend, distribution or right, and the amount and character of such dividend,
distribution or right; and (B) the date on which any such reorganization,
reclassification, transfer, consolidation, merger, dissolution, liquidation or
winding-up is expected to become effective and the record date for determining
stockholders entitled to vote thereon.

             (e) Reservation of Stock Issuable Upon Conversion. The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of Series A Preferred solely for the purpose of effecting the conversion
of this Note such number of its shares of Series A Preferred (and shares of its
Common Stock for issuance on conversion of such Series A Preferred) as shall
from time to time be sufficient to effect the conversion of the Note; and if at
any time the number of authorized but unissued shares of Series A Preferred (and
shares of its Common Stock for issuance on conversion of such Series A
Preferred) shall not be sufficient to effect the conversion of the entire
outstanding principal amount of this Note, without limitation of such other
remedies as shall be available to the holder of this Note, the Company will use
its best efforts to take such corporate action as may, in the opinion of
counsel, be necessary to increase its authorized but unissued shares of Series A
Preferred (and shares of its Common Stock for issuance on conversion of such
Series A Preferred) to such number of shares as shall be sufficient for such
purposes.

          13. Successors and Assigns. Neither this Note nor any of the rights,
interests or obligations hereunder may be assigned, by operation of law or
otherwise, in whole or in part, by the Company without the prior written consent
of the Holder or, prior to the termination of the Merger Agreement, by the
Holder without the prior written consent of the Company. Subject to the
foregoing and the  

                                      -17-
   18
restrictions on transfer described in Section 15 below, the rights and
obligations of the Company and the Holder shall be binding upon and benefit the
successors, assigns, heirs, administrators and transferees of the parties.

          14. WAIVER AND AMENDMENT. Any provision of this Note may be amended,
waived or modified upon the written consent of the Company and the Holder.

          15. TRANSFER OF THIS NOTE OR SECURITIES ISSUABLE ON CONVERSION HEREOF.
With respect to any offer, sale or other disposition of this Note or any
securities into which this Note may be converted, the Holder will give written
notice to the Company prior thereto, describing briefly the manner thereof,
together with a written opinion of the Holder's counsel, to the effect that such
offer, sale or other distribution may be effected without registration or
qualification under any federal or state law then in effect. Promptly upon
receiving such written notice and reasonably satisfactory opinion, if so
requested and subject to Section 13, the Company, as promptly as practicable,
shall notify the Holder that the Holder may sell or otherwise dispose of this
Note or such securities, all in accordance with the terms of the notice
delivered to the Company. If a determination has been made pursuant to this
Section 15 that the opinion of counsel for the Holder is not reasonably
satisfactory to the Company, the Company shall so notify the Holder promptly
after such determination has been made. Each Note thus transferred and each
certificate representing the securities thus transferred shall bear a legend as
to the applicable restrictions on transferability in order to ensure compliance
with the Act, unless in the opinion of counsel for the Company such legend is
not required in order to ensure compliance with the Act. The Company may issue
stop transfer instructions to its transfer agent in connection with such
restrictions.

          16. NOTICES. Any notice, request or other communication required or
permitted hereunder shall be in writing and shall be deemed to have been duly
given if personally delivered or mailed by registered or certified mail, postage
prepaid, or by recognized overnight courier or personal delivery, addressed
(i) if to the Holder, at such Holder's address set forth at the end of this
Agreement, or at such other address as such Holder shall have furnished the
Company in writing, or (ii) if to the Company, at its address set forth at the
end of this Agreement, or at such other address as the Company shall have
furnished to the Holder in writing. Any party hereto may by notice so given
change its address for future notice hereunder. Notice shall conclusively be
deemed to have been given when received.

          17. PAYMENT. Payment shall be made in lawful tender of the United
States.

of after-acquired Collateral, at the time Debtor acquires rights in the
Collateral, will be the owner thereof) and that no other Person has (or, in the
case of after-acquired Collateral, at the time Debtor acquires rights therein,
will have) any right, title, claim or interest (by way of Lien or otherwise) in,
against or to the Collateral, other than Permitted Liens; (b) Secured Party has
(or in the case of after-acquired Collateral, at the time Debtor acquires rights
therein, will have) a perfected security interest in the Collateral to the

hereafter produced Inventory, will be) produced in compliance with applicable
laws, including the Fair Labor Standards Act; (d) each Receivable is genuine and

preserve, protect and perfect the Collateral, the Lien granted to Secured Party
therein and the first priority of such Lien, except for Permitted Liens; (b) not
to use or permit any Collateral to be used (i) in violation of any provision of
any Transaction Document, (ii) in violation of any applicable law, rule or
regulation, or (iii) in violation of any policy of insurance covering the

charges, all Liens and all other charges now or hereafter imposed upon or

written notice to Secured Party, (i) not to change Debtor's name or place of
business (or, if Debtor has more than one place of business, its chief executive
office), or the office in which Debtor's records relating to Receivables are
kept, (ii) not to keep Collateral consisting of chattel paper at any location
other than its chief executive office set forth in item 1 of Attachment 2
hereto, and (iii) not to keep Collateral consisting of Equipment or Inventory at
any location other than the locations set forth in item 6 of Attachment 2
hereto, (e) to deposit, or cause to be deposited, all remittances and checks
received with respect to Receivables to an account of Debtor at a bank or other
depository institution which has been given notice of Secured Party's security
interest in such account in substantially the form of the Notice of Security
Interest which is attached hereto as Attachment 3, and in which account Secured
Party has a perfected security interest; (f) to procure, execute and deliver
from time to time any endorsements, assignments, financing statements and other
writings reasonably deemed necessary or appropriate by Secured Party to perfect,
maintain and protect its Lien hereunder and the priority thereof and, at Secured
Party's request, to deliver promptly to Secured Party all originals of
Collateral consisting of instruments other than negotiable instruments received
in the ordinary course of business; (g) to appear in and defend any action or
proceeding which may affect its title to or Secured Party's interest in the
Collateral; (h) if Secured Party gives value to enable Debtor to acquire rights
in or the use of any Collateral, to use such value for such purpose; (i) to keep
separate, accurate and complete records of the Collateral and to provide Secured
Party with such records and such other reports and information relating to the
Collateral as Secured Party may 




                                      -2-
   23
reasonably request from time to time; (j) except as permitted under the terms of
the Note, not to surrender or lose possession of (other than to Secured Party),
sell, encumber, lease, rent, or otherwise dispose of or transfer any Collateral
or right or interest therein, and to keep the Collateral free of all Liens
except Permitted Liens; (k) upon request by Secured Party, to type, print or
stamp conspicuously on the face of all original copies of all Collateral
consisting of chattel paper a legend satisfactory to Secured Party indicating
that such chattel paper is subject to the security interest granted hereby; (m)
to collect, enforce and receive delivery of the Receivables in accordance with
past practice until otherwise notified by Secured Party; (n) to comply with all
material requirements of law relating to the production, possession, operation,
maintenance and control of the Collateral (including the Fair Labor Standards
Act); and (o) to complete and deliver Attachment 2 to Secured Party as promptly
as practicable after the date hereof, and in any event within ten (10) days
following the date hereof.

         5.       Authorized Action by Agent. Debtor hereby irrevocably appoints
Secured Party as its attorney-in-fact and agrees that Secured Party may perform
(but Secured Party shall not be obligated to and shall incur no liability to
Debtor or any third party for failure so to do) any act which Debtor is
obligated by this Security Agreement to perform, and to exercise such rights and
powers as Debtor might exercise with respect to the Collateral, including the
right to (a) collect by legal proceedings or otherwise and endorse, receive and
receipt for all dividends, interest, payments, proceeds and other sums and
property now or hereafter payable on or on account of the Collateral; (b) enter
into any extension, reorganization, deposit, merger, consolidation or other
agreement pertaining to, or deposit, surrender, accept, hold or apply other
property in exchange for the Collateral; (c) insure, process and preserve the
Collateral; (d) make any compromise or settlement, and take any action it deems
advisable, with respect to the Collateral; (e) pay any Indebtedness of Debtor
relating to the Collateral; and (f) execute UCC financing statements and other
documents, instruments and agreements required hereunder; provided, however,
that Secured Party shall not exercise any such powers prior to the occurrence of
an Event of Default and shall only exercise such powers during the continuance
of an Event of Default. Debtor agrees to reimburse Secured Party upon demand for
any reasonable costs and expenses, including reasonable attorneys' fees, Secured
Party may incur while acting as Debtor's attorney-in-fact hereunder, all of
which costs and expenses are included in the Obligations. It is further agreed
and understood between the parties hereto that such care as Secured Party gives
to the safekeeping of its own property of like kind shall constitute reasonable
care of the Collateral when in Secured Party's possession; provided, however,
that Secured Party shall not be required to make any presentment, demand or
protest, or give any notice and need not take any action to preserve any rights
against any prior party or any other person in connection with the Obligations
or with respect to the Collateral.

         6.       Default and Remedies. Debtor shall be deemed in default under 
this Security Agreement upon the occurrence and during the continuance of an
Event of Default (as defined in the Note). Upon the occurrence and during the
continuance of any such Event of Default, Secured Party shall have the rights of
a secured creditor under the UCC, all rights granted by this Security Agreement
and by law, including the right to: (a) require Debtor to assemble the
Collateral and make it available to Secured Party at a place to be designated by
Secured Party; and (b) prior to the disposition of the Collateral, store,
process, repair or recondition it or otherwise prepare it for disposition in any
manner and to the extent Secured Party deems appropriate and in connection with
such preparation and disposition, without charge, use any trademark, trade name,
copyright, patent or technical process used by Debtor. Debtor hereby agrees that
ten (10) days' notice of any intended sale or disposition of any Collateral is
reasonable. In furtherance of Secured Party's rights hereunder, Debtor hereby
grants to Secured Party an irrevocable, non-exclusive license (exercisable
without royalty or other payment by Secured Party, but only in connection with
the exercise of remedies hereunder) to use, license or sublicense any patent,
trademark, trade name, copyright or other intellectual property in which 



                                      -3-
   24
Debtor now or hereafter has any right, title or interest together with the right
of access to all media in which any of the foregoing may be recorded or stored.

         7.       Miscellaneous.

                  (a)      Notices.  Except as otherwise provided herein, all

                  (b)      Nonwaiver. No failure or delay on Secured Party's
