     with an amount equal to an 18% annual yield from the date hereof on the
     Principal Amount (calculated after giving effect to any and all payments
     made by Borrower to Lender under the Debenture) through the date of
     redemption (the "Redemption Date").

          (b) The Holder may exercise its right to require that the Company

<PAGE>

     the average closing bid price for the Common Stock for the 20 consecutive
     trading days prior to the date of notice exceeds an amount equal to three
     times the Conversion Price then in effect, and the Common Stock is listed
     or quoted on the Nasdaq, the Nasdaq SmallCap System, American Stock
     Exchange or New York Stock Exchange; (ii) the average daily trading volume
     for the Common Stock for the 20 consecutive trading days prior to the date
     of the irrevocable notice shall be no less than 50,000 shares; (iii) the
     market price for the Common Stock at the time of notice reflects a
     price-to-earnings ratio of no greater than 25 times fully diluted earnings

     Stock issuable upon conversion of this Debenture shall have been fully
     registered under applicable U.S. securities laws. The Company's right of
     redemption is subject to the Holder's prior right of conversion of the
     Debenture.

          (b) Upon the Holder's notification to the Company in writing of its
     intent to sell, assign or transfer the Debenture pursuant to Section 14
     hereof, this Debenture is redeemable at the Borrower's option, in whole but

     pursuant to Sections 5(a) and (b) prior to maturity by giving notice
     thereof to the Holder of this Debenture as such name appears on the books
     of the Borrower, which notice shall specify the terms of redemption
     (including the place at which the Holder may obtain payment), the total
     redemption payment and the Redemption Date.

     6. CONVERSION RIGHT.

          (a) The Holder of this shall have the right, at Holder's option, at
     any time, to convert all, or, in multiples of $100,000, any part of this
     Debenture into such number of fully paid and nonassessable shares of Common
     Stock as provided herein. The Holder of this Debenture may exercise the
     conversion right by giving written notice (the "Conversion Notice") to
     Borrower of the exercise of such right and stating the name or names in
     which the stock certificate or stock certificates for the shares of Common
     Stock are to be issued and the address to which such certificates shall be
     delivered. The Conversion Notice shall be accompanied by the Debenture. The
     number of shares of Common Stock that shall be issuable upon conversion of
     the Debenture shall equal the outstanding Principal Amount of the Debenture
     divided by the Conversion Price (as defined below) and in effect on the
     date the Conversion Notice is given; provided, however, that in the event
     that this Debenture shall have been partially redeemed, shares of Common
     Stock shall be issued pro rata, rounded to the nearest whole share.
     Conversion shall be deemed to have been effected on the date the Conversion
     Notice is received (the "Conversion Date"). In the case of any Debenture
     called for redemption, the conversion rights will expire at the close of
     business on the Redemption Date. Within 20 business days after receipt of
     the Conversion Notice, Borrower shall issue and deliver by hand against a
     signed receipt therefor or by United States registered mail, return receipt
     requested, to the address designated in the Conversion Notice, a stock
     certificate

                                      -3-
<PAGE>

     or stock certificates of Borrower representing the number of shares of
     Common Stock to which Holder is entitled and a check or cash in payment of
     all interest accrued and unpaid on the Debenture up to and including the
     Conversion Date. The conversion rights will be governed by the following
     provisions:

          (b) CONVERSION PRICE. On the issue date hereof and until such time as
     an adjustment shall occur, the Conversion Price shall be $0.50 per share;
     provided, however, that the Conversion Price shall be subject to adjustment
     at the times and in accordance with the provisions set forth
     below.

              (i)    ADJUSTMENT FOR ISSUANCE OF SHARES AT LESS THAN THE
                     CONVERSION PRICE. If and whenever any Additional Common
                     Stock (as defined below) shall be issued by Borrower (the
                     "Stock Issue Date") for a consideration per share less than
                     the Conversion Price, then in each such case the initial
                     Conversion Price shall be reduced to a new Conversion Price
                     in an amount equal to the price per share for the
                     Additional Common Stock then issued, if issued in
                     connection with a sale of shares, or the value of the
                     Additional Common Stock then issued, as determined in
                     accordance with generally accepted accounting principles,
                     if issued other than for cash, and the number of shares
                     issuable to Holder upon conversion shall be proportionately
                     increased; and, in the case of Additional Common Stock
                     issued without consideration, the initial Conversion Price
                     shall be reduced in amount and the number of shares issued
                     upon conversion shall be increased in an amount so as to
                     maintain for the Holder the right to convert the Debenture
                     into shares equal in amount to the same percentage interest
                     in the Common Stock of the Company as existed for the
                     Holder immediately preceding the Stock Issue Date.

              (ii)   SALE OF SHARES. In case of the issuance of Additional
                     Common Stock for a consideration part or all of which shall
                     be cash, the amount of the cash consideration therefor
                     shall be deemed to be the gross amount of the cash paid to
                     Borrower for such shares, before deducting any underwriting
                     compensation or discount in the sale, underwriting or
                     purchase thereof by underwriters or dealers or others
                     performing similar services or for any expenses incurred in
                     connection therewith. In case of the issuance of any shares
                     of Additional Common Stock for a consideration
                     part or all of which shall be other than cash, the amount
                     of the consideration therefor, other than cash, shall be
                     deemed to be the then fair market value of the property
                     received.

              (iii)  STOCK SPLITS, SUBDIVISIONS OR COMBINATIONS. In the event of
                     a stock split or subdivision of shares of Common Stock into
                     a greater

                                      -4-
<PAGE>

                     number of shares, the Conversion Price shall be
                     proportionately decreased and the number of shares of
                     Common Stock which shall be issued upon such conversion
                     shall be proportionally increased, and in the event of a
                     combination of shares of Common Stock into a smaller number
                     of shares, the Conversion Price shall be proportionately
                     increased and the number of shares of Common Stock which
                     shall be issued upon such conversion shall be
                     proportionally decreased, such increase or decrease, as the
                     case may be, becoming effective at the record date.

              (iv)   STOCK DIVIDENDS. Shares of Common Stock issued as a
                     dividend or other distribution on any class of capital
                     stock of Borrower shall be deemed to have been issued
                     without consideration.

              (v)    EXCEPTIONS. The term "Additional Common Stock" herein shall
                     mean all shares of Common Stock or securities convertible
                     or exercisable into shares of Common Stock hereafter issued
                     by Borrower (including Common Stock held in the treasury of
                     Borrower), except (A) Common Stock issued upon the
                     conversion of any of the Debentures or the Renaissance
                     Debentures; (B) Common Stock issuable upon exercise of
                     presently outstanding warrants or employee or director
                     stock options; or (C) Common Stock issuable upon exercise
                     of stock options to be granted in the future to employees
                     or directors pursuant to Borrower's existing stock option
                     plans.

          (c) ADJUSTMENT FOR MERGERS AND CONSOLIDATIONS. In the event of any
     consolidation or merger of the Company with or into, or the sale of all or
     substantially all of the properties and assets of the Company, to any
     person, and in connection therewith, consideration is payable to holders of
     Common Stock in cash, securities or other property, then as a condition of
     such consolidation, merger or sale, lawful provision shall be made, and
     duly executed documents evidencing the same shall be delivered to the
     Holder, so that the Holder shall have the right at any time prior to the
     maturity of this Debenture to purchase, at a total price equal to the
     Conversion Price immediately prior to such event, the kind and amount of
     cash, securities or other property receivable in connection with such
     consolidation, merger or sale, by a holder of the same number of shares of
     Common Stock as were convertible by the Holder immediately prior to such
     consolidation, merger or sale. In any such case, appropriate provisions
     shall be made with respect to the rights and interest of the Holder so that
     the provisions hereof shall thereafter be applicable with respect to any
     cash, securities or property deliverable upon exercise hereof.
     Notwithstanding the foregoing, (i) if the Company merges or consolidates
     with, or sells all or substantially all of its property and assets to, any
     other person, and consideration is payable to holders of Common Stock in
     exchange for their Common Stock in connection with such merger,
     consolidation or sale which consists solely of cash, or (ii) in the event
     of the dissolution, liquidation or winding up of the

                                      -5-
<PAGE>

     Company, then the Holder shall be entitled to receive distributions on the
     date of such event on the same basis with holders of Common Stock as if
     this Debenture had been converted immediately prior to such event, less the
     Conversion Price. Upon receipt of such payment, if any, the rights of the
     Holder shall terminate and cease and this Debenture shall expire. In case
     of any such merger, consolidation or sale of assets, the surviving or
     acquiring person and, in the event of any dissolution, liquidation or
     winding up of the Company, the Company shall promptly, after receipt of
     this surrendered Debenture, make payment by delivering a check in such
     amount as is appropriate (or, in the case of consideration other than cash,
     such other consideration as is appropriate) to such person as it may be
     directed in writing by the Holder surrendering this Debenture.

          (d) DISTRIBUTIONS. In the event of distribution to all Common Stock
     holders of any securities, cash or properties or assets or other rights to
     purchase securities or assets, then, after such event, this debenture will
     also be convertible into the kind and amount of securities, cash and other
     property which the Holder would have been entitled to receive if the Holder
     owned the Common Stock issuable upon conversion of the Debenture
     immediately prior to the occurrence of such event.

          (e) CAPITAL REORGANIZATION AND RECLASSIFICATION. In case of any
     capital reorganization or reclassification of the Common Stock of Borrower
     (other than a change in par value or as a result of a stock dividend,
     subdivision, split up or combination of shares), this Debenture shall be
     convertible into the kind and number of shares of stock or other securities
     or property of Borrower to which the Holder of the Debenture would have
     been entitled to receive if the Holder owned the Common Stock issuable upon
     conversion of the Debenture immediately prior to the occurrence of such
     event. The provisions of the immediately foregoing sentence shall similarly
     apply to successive reorganizations, reclassifications, consolidations,
     exchanges, leases, transfers or other dispositions or other share
     exchanges.

          (f) NOTICE. In the event Borrower shall propose to take any action
     which shall result in an adjustment in the Conversion Price, Borrower shall
     give notice to the Holder of this Debenture, which notice shall specify the
     record date, if any, with respect to such action and the date on which such
     action is to take place. Such notice shall be given on or before the
     earlier of 10 days before the record date or the date which such action
     shall be taken. Such notice shall also set forth all facts (to the extent
     known) material to the effect of such action on the Conversion Price and
     the number, kind or class of shares or other securities or property which
     shall be deliverable or purchasable upon the occurrence of such action or
     deliverable upon conversion of this Debenture.

          (g) CERTIFICATE. Following completion of an event which results in an
     adjustment to the Conversion Price, Borrower shall furnish to the Holder of
     this Debenture a statement, signed by the Chief Financial Officer and the
     Secretary of the Borrower, of the facts creating such adjustment and
     specifying the resultant adjusted Conversion Price then in effect, which
     statement shall constitute an amendment to this Debenture.


                                      -6-
<PAGE>

          (h) In the event of an adjustment to the Conversion Price due to a
     sale of securities by the Borrower below the Conversion Price which would
     result in the holders of all debentures evidencing the Loan having the
     right to acquire more than 20% of the then outstanding shares of Common
     Stock, on a fully-diluted basis, the Borrower agrees to hold a vote of the
     shareholders within 150 days to authorize such an adjustment; provided such
     approval is required by Nasdaq. In the event the shareholders reject the
     authorization, the Holder shall have the right to cause the Company to
     redeem the Debenture in accordance with the provisions of Section 4.

     7. ONE-TIME ADJUSTMENT TO CONVERSION PRICE.

          (a) Notwithstanding the of Section 6 hereof, if the Company does not
     achieve $3,000,000 of Trailing Twelve Months EBITDA at the end of fiscal
     year 2002, and the market price of the Common Stock is below the Conversion
     Price at the time of publication of the Company's results for that period,
     then the Conversion Price shall be automatically adjusted downward to an
     amount equal to average closing bid price of the Common Stock, as reported
     in THE WALL STREET JOURNAL, for the ten consecutive trading days (the
     "Trading Period") following Borrower's public press release of its fiscal
     year 2002 financial results. If an adjustment occurs pursuant to this
     Section 7, then the Borrower shall furnish to the holder of this Debenture
     a statement, within ten days of the occurrence thereof, signed by the Chief
     Financial Officer and the Secretary of Borrower, of the facts creating such
     adjustment and specifying the adjusted Conversion Price then in effect. The
     Holder shall not convert this Debenture or sell any shares of Common Stock
     during the Trading Period.

          (b) Under no circumstance will this adjustment to the Conversion Price
     cause the holders of all debentures evidencing the Loan to acquire greater
     than 20% of the Borrower's then outstanding shares of Common Stock. In the
     event that this adjustment to the Conversion Price allows the holders of
     all debentures evidencing the Loan to acquire greater than 20% of the
     Borrower's then outstanding shares of Common Stock, then the debenture
     holders will be entitled to decrease the Conversion Price, so that their
     potential and actual ownership is equal to twenty percent (20%) of the
     issued and outstanding Common Stock, on a fully-diluted basis, at the time
     this adjustment becomes effective.

     8. RESERVATION OF SHARES. Borrower warrants and agrees that it shall at all
times reserve and keep available, free from preemptive rights, sufficient
authorized and unissued shares of Common Stock or treasury shares of Common
Stock necessary to effect conversion of this Debenture.

     9. TAXES. The Company shall pay any documentary or other transactional
taxes attributable to the issuance or delivery of this Debenture or the shares
of Common Stock issued upon conversion by the Holder (excluding any federal,
state or local income taxes and any franchise taxes or taxes imposed upon the
Holder by the jurisdiction, or any political subdivision thereof, under which
such Holder is organized or is qualified to do business).

     10. DEFAULT.

          (a) EVENT OF DEFAULT. An "Event of Default" shall exist if an of
     Default" (as defined in the Loan Agreement) shall occur and be continuing.

          (b) REMEDIES UPON EVENT OF DEFAULT. If an Event of Default shall have
     occurred and be continuing, then the Holder may exercise any one or more of
     the rights and remedies provided in the Loan Documents, as the Holder, in
     its sole discretion, may deem necessary or appropriate.

          (c) REMEDIES NONEXCLUSIVE. right, power or remedy of the Holder hereof
     upon the occurrence of any Event of Default as provided for in this
     Debenture or now or hereafter existing at law or in equity or by statute
     shall be cumulative and concurrent and shall be in addition to every other
     right, power or remedy provided for in this Debenture or now or hereafter
     existing at law or in equity or by statute, and the exercise or beginning
     of the exercise by the Holder or transferee hereof of any one or more of
     such rights, powers or remedies shall not preclude the simultaneous or
     later exercise by the Holder of any or all such other rights, powers or
     remedies.


          (d) EXPENSES. Upon the occurrence of a Default or an Event of Default,
     which occurrence is not cured within the notice provisions, if any provided
     therefore, Borrower agrees to pay and shall pay all reasonable costs and
     expenses (including attorneys' fees and expenses) incurred by the Holder in
     connection with the preservation and enforcement of Holder's rights under
     the Loan Agreement, the Debenture, or any other Loan Document.

     11. FAILURE TO ACT AND WAIVER. No failure or delay by the Holder hereof to
require the performance of any term or terms of this Debenture or not to
exercise any right or any remedy shall constitute a waiver of any such term or
of any right or of any default, nor shall such delay or failure preclude the
Holder hereof from exercising any such right, power or remedy at any later time
or times. By accepting payment after the due date of any amount payable under
this Debenture, the Holder hereof shall not be deemed to waive the right either
to require payment when due of all other amounts payable, or to later declare a
default for failure to effect such payment of any such other amount. The failure
of the Holder of this Debenture to give notice of any failure or breach of the
Borrower under this Debenture shall not constitute a waiver of any right or
remedy in respect of such continuing failure or breach or any subsequent failure
or breach.

     12. CONSENT TO JURISDICTION. The Company hereby agrees and consents that
any action, suit or proceeding arising out of this Debenture may be brought in
any state or federal court in the State of New York, including the United States
District Court for the Southern District of New York, or in any other court
having jurisdiction over the subject matter, all at the sole election of the
Holder hereof, and by the issuance and execution of this Debenture, the Borrower
irrevocably consents to the jurisdiction of each such court. The Company hereby
irrevocably appoints CT Corporation System, New York, New York, as agent for the
Borrower

                                      -8-

to accept service of process for and on behalf of the Borrower in any action,
suit or proceeding arising out of this Debenture. Except for default in payment
of interest or principal when and as they become due, and except as otherwise
specifically set forth herein or otherwise agreed to in writing by the parties,
any action, dispute, claim or controversy (all such herein called "Dispute")
between or among the parties as to the facts or the interpretation of the
Debenture shall be resolved by arbitration as set forth in the Loan Agreement.

     13. HOLDER'S RIGHT TO REQUEST MULTIPLE DEBENTURES. The Holder shall, upon
written request and presentation of the Debenture, have the right, at any
interest payment date, to request division of this Debenture into two or more
instruments, each of such to be in such amounts as shall be requested; provided
however, that no Debenture shall be issued in denominations of face amount less
than $100,000.

     14. TRANSFER. Subject to Section 12.07 of the Loan Agreement, this
Debenture may be transferred on the books of the Borrower by the registered
Holder hereof, or by Holder's attorney duly authorized in writing, in multiples
of $100,000 only upon (i) delivery to the Borrower of a duly executed assignment
of the Debenture, or part thereof, to the proposed new Holder, as well as an
executed investor representation letter signed by the proposed transferee and
such other transfer documents and instruments as the Company may reasonably
request, along with a current notation of the amount of payments received and
net Principal Amount yet unfunded, and presentment of such Debenture to the
Borrower for issue of a replacement Debenture, or Debentures, in the name of the
new Holder, (ii) the designation by the new Holder of the Lender's agent for
notice, such agent to be the sole party to whom Borrower shall be required to
provide notice when notice to Holder is required hereunder and who shall be the
sole party authorized to represent Lender in regard to modification or waivers
under the Debenture, the Loan Agreement, or other Loan Documents; and any
action, consent or waiver (other than a compromise of principal and interest)
when given or taken by Lender's agent for notice, shall be deemed to be the
action of the holders of a majority in amount of the Principal Amount of the
Debenture, as such holders are recorded on the books of the Borrower, and (iii)
in compliance with the legend to read as follows:

                  "This Debenture has not been registered under the Securities
                  Act of 1933, as amended ("Act"), or applicable state
                  securities laws ("State Acts"), and shall not be offered,
                  sold, pledged, hypothecated, or otherwise transferred, unless
                  such transfer is made in compliance with the Act and the State
                  Acts."

     Holder shall notify the Company in writing of its intent to sell, assign or
transfer the Debenture prior to any such sale, assignment or transfer.

     The Company shall be entitled to treat any holder of record of the
Debenture as the Holder in fact thereof and of the Debenture and shall not be
bound to recognize any equitable or other claim to or interest in this Debenture
in the name of any other person, whether or not it shall have express or other
notice thereof, except as otherwise provided by applicable law.

     15. NOTICES. All notices and communications under this Debenture shall be
in writing and shall be either delivered in person or by overnight service, such
as FedEx, and accompanied by a signed receipt therefor; or mailed first-class
United States certified mail, return receipt requested, postage prepaid, and
addressed as follows: (i) if to the Borrower at its address for notice as stated
in the Loan Agreement; and (ii) if to the Holder of this Debenture, to the
address (a) of such Holder as it appears on the books of the Borrower or (b) in
the case of a partial assignment to one or more Holders, to the Lender's agent
for notice, as the case may be. Any notice of communication shall be deemed
given and received as of the date of such delivery if delivered; or if mailed,
then three days after the date of mailing.

     16. MAXIMUM INTEREST RATE.

          (a) Regardless of any provision contained in this Debenture, Lender
     shall never be entitled to receive, collect or apply as interest on the
     Debenture any amount in excess of interest calculated at the Maximum Rate
     (as defined below), and, in the event that Lender ever receives, collects
     or applies as interest any such excess, the amount which would be excessive
     interest shall be deemed to be a partial prepayment of principal and
     treated hereunder as such; and, if the principal amount of the Debenture is
     paid in full, any remaining excess shall forthwith be paid to Borrower. In
     determining whether or not the interest paid or payable under any specific
     contingency exceeds interest calculated at the Maximum Rate, Borrower and
     Lender shall, to the maximum extent permitted under applicable law, (i)
     characterize any non principal payment as an expense, fee or premium rather
     than as interest, (ii) exclude voluntary prepayments and the effects
     thereof, and (iii) amortize, pro rate, allocate and spread, in equal parts,
     the total amount of interest throughout the entire contemplated term of the
     Debenture; provided that, if the Debenture is paid and performed in full
     prior to the end of the full contemplated term thereof, and if the interest
     received for the actual period of existence thereof exceeds interest
     calculated at the Maximum Rate, Lender shall refund to Borrower the amount
     of such excess or credit the amount of such excess against the principal
     amount of the Debenture and, in such event, Lender shall not be subject to
     any penalties provided by any laws for contracting for, charging, taking,
     reserving or receiving interest in excess of interest calculated at the
     Maximum Rate.

          (b) "Maximum Rate" shall mean, on any day, the highest nonusurious
     rate of interest (if any) permitted by applicable law on such day that, at
     any time or from time to time, may be contracted for, taken, reserved,
     charged or received on the Indebtedness evidenced by the Debenture under
     the laws which are presently in effect of the United States of America or
     by the laws of any other jurisdiction which are or may be applicable to the
     Holders of the Debenture and such Indebtedness or, to the extent permitted
     by law, under such applicable laws of the United States of America or by
     the laws of any other jurisdiction which are or may be applicable to the
     Holder of the Debenture and which may hereafter be in effect and which
     allow a higher maximum nonusurious interest rate than applicable laws now
     allow.
