Bridge Financing Notes that have been authorized by the Company (the "Series 1
Bridge Notes") and are alike except for principal amount and issue date, and are
in registered form. This Series 1 Bridge Note replaces the Bridge Note

the Company in favor of SovCap Equity Partners, Ltd. in connection with the
First Closing and tendered to and cancelled by the Company on the date hereof as
part of the making and issuance of this Series 1 Bridge Note. This Series 1
Bridge Note is convertible, into shares of the Company's Common Stock, $.01 par

conversion, the Common Stock so issued shall be subject to all terms and
conditions and shall enjoy all rights, privileges, and preferences applicable to
such Common Stock under the Company's Certificate of Incorporation (the
"Certificate of Incorporation"). The Common Stock issuable upon conversion of
this Series 1 Bridge Note (the "Conversion Shares") are entitled to registration
rights pursuant to a Registration Rights Agreement between Holder, the Company,
and certain other signatures thereto dated March 16, 1999, as amended (the
"Registration Rights Agreement"). This Series 1 Bridge Note is secured by
certain specified equipment of the Company having a value of approximately 130%
of the principal amount of this Series 1 Bridge Note pursuant to the terms of a
Series 1 Bridge Note Purchase and Security Agreement dated March 16, 1999, as
amended (the "Purchase Agreement"), and is otherwise entitled to all of the
rights and benefits thereunder.

     Section 2. Office for Registration and Conversion. The Company shall
maintain an office where this Series 1 Bridge Note shall be surrendered or
presented for registration of transfers or exchanges and conversions. This
office will initially be located at the offices of the Company at 120 Ricefield
Lane, Hauppauge, New York 11788. The Company shall keep a register of the Series
1 Bridge Notes and of their transfer and exchange, including the names and
addresses of Holders of the Series 1 Bridge Notes. Holder shall give the Company
notice of any change in Holder's address to the office indicated in this Section
2. Upon two (2) business days written request, the Company shall permit Holder

     Section 3. Redemption.

          (a) Mandatory Redemption. If this Series 1 Bridge Note is outstanding
     on the Maturity Date, this Series 1 Bridge Note shall be due and payable as
     follows:

               (i) if on the Maturity Date a Registration Statement is effective
          with respect to the Conversion Shares, the Company shall give written
          notice to Holder of its intent to redeem the then outstanding
          principal amount of this Series 1 Bridge Note, which notice shall
          state the election of the Company to pay the redemption price in cash
          or by conversion of this Series 1 Bridge Note into Common Stock, in
          the manner contemplated by Section 3(c) hereof. Regardless of the
          manner in which paid, the redemption price (the "Maturity Date
          Redemption Price") shall be equal to 117.5% of the then outstanding
          principal amount of this Series 1 Bridge Note plus accrued and unpaid
          interest thereon at the Note Rate through and including the Maturity
          Date and at the Default Rate after the Maturity Date through and
          including the date the payment is disbursed (whether by issuance of
          Conversion Shares or a payment in cash).

               (ii) if on the Maturity Date a Registration Statement is not
          effective with respect to the Conversion Shares, Holder may, in
          addition to all other rights and remedies of Holder hereunder and
          under the Purchase Agreement, elect to make written demand to the
          Company to redeem, all or part of the then outstanding principal under
          this Series 1 Bridge Note. Such demand shall specify Holder's election
          to accept payment of the redemption price in cash or by conversion of
          this Series 1 Bridge Note into Common Stock, in the manner
          contemplated by Section 3(c) hereof. The Company shall have two (2)
          Business Days after its receipt of such demand to confirm its
          intention to redeem this Series 1 Bridge Note by tendering to Holder
          either (A) cash or (B) Conversion Shares (as specified in Holder's
          demand), in the manner contemplated by Section 3(c) hereof. In either
          case the redemption price shall be equal to the Maturity Date
          Redemption Price.

               (iii) The date of any redemption under either subparagraph (i) or
          (ii) above shall be referred to as a "Redemption Date."

          (b) Voluntary Redemption. At any time from and after the Original
     Issue Date up to but not including the Maturity Date, the Company may, at
     its option, call and redeem this Series 1 Bridge Note, at the redemption
     price set forth in subparagraph (i), below, plus accrued and unpaid
     interest on such redeemed amount through and including the Voluntary
     Redemption Date, as such term is defined below (such redemption being the
     "Voluntary Redemption"), under and in accordance with the following terms
     and procedures:

               (i) The Company at its option prior to the Maturity Date may
          redeem this Series 1 Bridge Note at the Redemption Price set forth
          below plus all accrued and unpaid interest on the principal amount
          through and including the Voluntary Redemption Date (the "Voluntary
          Redemption Price") as of a Voluntary Redemption Date:

               (ii) At least ten (10) days before a Voluntary Redemption, the
          Company shall mail a notice of redemption to Holder, stating (A) the
          redemption date, which shall be a business day in New York, New York

          this Series 1 Bridge Note must be presented to receive payment if
          required pursuant to paragraph (iv) below. Once notice of redemption
          is mailed and the Company shall have complied with paragraph (iii)
          below, the Voluntary Redemption Price shall become due and payable on
          the Voluntary Redemption Date.

               (iii) On or before the third (3rd) day prior to the Voluntary
          Redemption Date, the Company shall deposit into a bank trust account
          for the benefit of the Holder of this Series 1 Bridge Note money
          sufficient to pay the Redemption Price and all accrued and unpaid
          interest.

               (iv) The Company may, at its option, require as a condition to
          the receipt of a payment pursuant to this Section 3(b) that Holder
          present the Series 1 Bridge Notes to the Person specified in paragraph
          (ii) above for surrender.

               (v) No Voluntary Redemption of this Series 1 Bridge Note can be
          effected after the 179th day after the Original Issue Date.

          (c) Conversion into Common Stock in Lieu of Payments.

               (i) In lieu of payment of cash to Holder pursuant to Section
          3(a)(i) hereof and Section 3(b) hereof, the Company may, elect to pay
          all or part of the Maturity Date Redemption Price or the Voluntary
          Redemption Price in Conversion Shares, under the terms of Section 3(d)
          hereof.

               (ii) In lieu of cash, pursuant to Section 3(a)(ii) hereof, Holder
          may require the Company to pay all or part of the Maturity Date
          Redemption Price in Conversion Shares, under the terms of Section 3(d)
          hereof.

     The Repricing Warrant shall apply to each share of Common Stock received by
     Holder pursuant to this Section 3(c).

          (d) The number of shares of Common Stock issuable in payment of the
     Mandatory Redemption Price or the Voluntary Redemption Price is equal to
     the quotient of the Mandatory



                                      -3-
<PAGE>

     Redemption Price or the Voluntary Redemption Price (as the case may be)
     divided by $1.1375 (the "Conversion Price"). Fractional shares will not be
     issued. In lieu of any fraction of a share, the Company shall deliver its
     check for the dollar amount of the less-than full share remainder.

     Section 4. Method of Payment.

          (a) Interest accruing through and including the Maturity Date shall be
     computed at the Note Rate. Interest accruing after the Maturity date shall
     be computed at the Default Rate. Accrued and unpaid interest shall be due
     and payable at the time the principal and premium of this Series 1 Bridge
     Note is paid. All such interest shall be computed on the basis of the
     actual number of days elapsed during any interest period in a year of 360
     days. Interest shall begin to accrue on the Original Issue Date.

          (b) The Company shall pay interest and principal on this Series 1
     Bridge Note (except defaulted interest) to the Person who is the registered
     Holder of this Series 1 Bridge Note on the day on which the interest or
     principal payment is due. If the Company defaults in a payment of interest
     on this Series 1 Bridge Note, it may pay the defaulted interest, plus any
     interest on the defaulted interest if permitted provided by Section 4(d)
     below, to the Person who is the registered Holder of this Series 1 Bridge
     Note on the date such payment is made.

          (c) The Company shall pay interest by check payable in money of the
     United States of America that at the time of payment is legal tender for
     public and private debts. Payments of interest shall be mailed to Holder's
     address shown in the register maintained pursuant to Section 2; provided
     however, that with respect to the final payment of principal and accrued
     and unpaid interest necessary to pay this Series 1 Bridge Note in full, to
     receive such payment Holder must surrender this Series 1 Bridge Note for
     cancellation to the Company or to a paying agent appointed by the Company.
     Principal and interest shall be considered paid on the date due, and no
     interest shall accrue thereafter, if there is on deposit on that date, in a
     bank trust account for the benefit of Holder of this Series 1 Bridge Note,
     money sufficient to pay the Redemption Price and all accrued and unpaid
     interest due under this Series 1 Bridge Note.

     Section 5. Conversion Price and Adjustments.

          (a) At anytime after the Maturity Date, Holder may convert all or any
     portion of the Redemption Price and accrued and unpaid interest due on this
     Series 1 Bridge Note into shares of Common Stock.

          (b) If Holder elects to convert less than the full Redemption Price of
     this Series 1 Bridge Note, such conversion shall be permitted only in one
     hundred (100)-share increments unless the Company has given its
     contemporaneous consent to conversion of an odd lot. The provisions hereof
     that apply to conversion of the entire Redemption Price of this Series 1
     Bridge Note shall also apply to conversion of a portion of the Redemption
     Price. Upon surrender of the Series 1 Bridge Note for conversion in part,
     the Company shall issue new Series 1 Bridge Notes in substantially the same
     form as this Series 1 Bridge Note, except that the principal amount shall
     be reduced by the principal amount so converted (exclusive of the
     redemption premium).

          (c) The number of shares of Common Stock issuable upon conversion of
     this Series 1 Bridge Note is equal to the quotient of the Redemption Price
     of this Series 1 Bridge Note being converted divided by Conversion Price.
     Fractional shares will not be issued. In lieu of any fraction of a share,
     the Company shall deliver its check for the dollar amount of the less than
     full share remainder. Accrued and unpaid interest shall be included in
     computing the number of



                                      -4-
<PAGE>

     Conversion Shares issuable upon conversion of this Series 1 Bridge Note.
     Interest shall cease to accrue on that portion of the Redemption Price
     converted from and after the Conversion Date.

     Section 6. Procedures for Conversion, and Issuance of Conversion Shares.

          (a) Holders' Delivery Requirements. To convert this Series 1 Bridge
     Note into Common Stock, (the "Conversion Date"), the Holder hereof shall
     (A) deliver or transmit by facsimile, for receipt on or prior to 11:59
     P.M., Eastern Time, on such date, a copy of a fully executed notice of
     conversion in the form attached hereto as Exhibit A (the "Conversion
     Notice") to the Company or its designated Transfer Agent, and (B) surrender
     to a common carrier for delivery to the Company or the Transfer Agent as
     soon as practicable following such date, the original Series 1 Bridge Note
     being converted (or an indemnification undertaking with respect to such
     shares in the case of the loss, theft, or destruction of the Series 1
     Bridge Note) and the originally executed Conversion Notice. The date the
     Company receives the Conversion Note and this Series 1 Bridge Note is
     hereinafter the "Conversion Date."

          (b) Company's Response. Upon receipt by the Company of a facsimile
     copy of a Conversion Notice, the Company shall immediately send, via
     Facsimile, a confirmation of receipt of such Conversion Notice to Holder.
     Upon receipt by the Company or the Transfer Agent of the Series 1 Bridge
     Note to be converted pursuant to a Conversion Notice, together with the
     originally executed Conversion Notice, the Company or the Transfer Agent
     (as applicable) shall, within five (5) business days following the date of
     receipt, (A) issue and surrender to a common carrier for overnight delivery
     to the address as specified in the Conversion Notice, a certificate,
     registered in the name of Holder or its designee, for the number of shares
     of Common Stock to which Holder shall be entitled or (B) credit the
     aggregate number of shares of Common Stock to which such Holder shall be
     entitled to the Holder's or its designee's balance account at The
     Depository Trust Company.

          (c) Record Holder. The Person or persons entitled to receive the
     shares of Common Stock issuable upon a conversion of this Series 1 Bridge
     Note shall be treated for all purposes as the "Record Holder" or Holder of
     such shares of Common Stock on the Conversion Date.

          (d) Company's Failure to Timely Convert. If the Company shall fail to
     issue to Holder within five (5) business days following the date of receipt
     by the Company or the Transfer Agent of this Series 1 Bridge Note to be
     converted pursuant to a Conversion Notice, a certificate for the number of
     shares of Common Stock to which each Holder is entitled upon Holder's
     conversion of this Series 1 Bridge Note, in addition to all other available
     remedies which such Holder may pursue hereunder and under the Purchase
     Agreement between the Company and the initial Holder of this Series 1
     Bridge Note (including indemnification pursuant to Section 7.18 thereof),
     the Company shall pay additional damages to Holder on each day after the
     fifth (5th) business day following the date of receipt by the Company or
     the Transfer Agent an amount equal to 1.0% of the product of (A) the number
     of shares of Common Stock not issued to Holder and to which Holder is
     entitled multiplied by (B) the Closing Bid Price of the Common Stock on the
     business day following the date of receipt by the Company or the Transfer
     Agent of the Conversion Notice. The foregoing notwithstanding, Holder at
     its option may withdraw a Conversion Notice, and remain a Holder of this
     Series 1 Bridge Note, if Holder has otherwise complied with this Section 6.

          (e) If any adjustment to the Conversion Price to be made pursuant to
     Section 7 becomes effective immediately after a record date for an event as
     therein described, and conversion occurs prior to such event but after the
     record date, the Company may defer issuing, delivering, or paying to Holder
     any additional shares of Common Stock or check for any cash remainder
     required



                                      -5-
<PAGE>

     by reason of such adjustment until the occurrence of such event, provided
     that the Company delivers to Holder a due bill or other appropriate
     instrument evidencing the Holders' right to receive such additional shares
     or check upon the occurrence of the event giving rise to the adjustment.

          (f) Until such time as this Series 1 Bridge Note has been fully
     redeemed, the Company shall reserve out of its authorized but unissued
     Common Stock enough shares of Common Stock to permit the conversion of the
     entire Redemption Price and all accrued and unpaid interest due on this
     Series 1 Bridge Note at any time. All shares of Common Stock issued upon
     conversion of this Series 1 Bridge Note shall be fully paid and
     nonassessable. The Company covenants that if any shares of Common Stock,
     required to be reserved for purposes of conversion of this Series 1 Bridge
     Note hereunder, require registration with or approval of any governmental
     authority under any federal or state law or listing upon any national
     securities exchange before such shares may be issued upon conversion, the
     Company shall in good faith, as expeditiously as possible, endeavor to
     cause such shares to be duly registered, approved or listed, as the case
     may be.

     Section 7. Adjustments to Conversion Price. The Conversion Price shall be
subject to adjustment from time to time as follows:

          (a) If the Company at any time subdivides (by any stock split, stock
     dividend, recapitalization, or otherwise) one or more classes of its
     outstanding shares of Common Stock into a greater number of shares, the
     Conversion Price in effect immediately prior to such subdivision will be
     proportionately reduced. If the Company at any time combines (by
     combination, reverse stock split, or otherwise) one or more classes of its
     outstanding shares of Common Stock into a smaller number of shares, the
     Conversion Price in effect immediately prior to such combination will be
     proportionately increased.

          (b) Prior to the consummation of any Organic Change (as defined
     below), the Company will make appropriate provision (in form and substance
     satisfactory to the Holder to insure that Holder will thereafter have the
     right to acquire and receive in lieu of, or in addition to, (as the case
     may be) the shares of Common Stock immediately theretofore acquirable and
     receivable upon the conversion of this Holder's Series 1 Bridge Note, such
     shares of stock, securities, or assets as may be issued or payable with
     respect to, or in exchange for, the number of shares of Common Stock
     immediately theretofore acquirable and receivable upon the conversion of
     this Series 1 Bridge Note had such Organic Change not taken place. In any
     such case, the Company will make appropriate provision (in form and
     substance satisfactory to Holder with respect to such Holder's rights and
     interests to insure that the provisions of this Section 7b) and Sections
     7(c) and 7(d) below will thereafter be applicable. The Company will not
     effect any such consolidation, merger, or sale, unless prior to the
     consummation thereof the successor entity (if other than the Company)
     resulting from consolidation or merger or the entity purchasing such assets
     assumes, by written instrument (in form and substance satisfactory to
     Holder, the obligation to deliver to Holder such shares of stock,
     securities, or assets as, in accordance with the foregoing provisions, that
     Holder may be entitled to acquire. For purposes of this Agreement, "Organic
     Change" means any recapitalization, reorganization, reclassification,
     consolidation, merger, or sale of all or substantially all of the Company's
     assets to another Person (as defined below), or other similar transaction
     which is effected in such a way that holders of Common Stock are entitled
     to receive (either directly or upon subsequent liquidation) stock,
     securities, or assets with respect to or in exchange for Common Stock; and
     "Person" means an individual, a limited liability company, a partnership, a
     joint venture, a corporation, a trust, an unincorporated organization, and
     a government or any department or agency thereof.


                                      -6-

     Section 8. Notices. The Company shall give the following notices at the
times specified:

          (a) Immediately upon any adjustment of the Conversion Price, the
     Company will give written notice thereof to Holder, setting forth in
     reasonable detail and certifying the calculation of such adjustment.

          (b) The Company will give written notice to Holder, at least twenty
     (20) days prior to the date on which the Company closes its books or takes
     a record (i) with respect to any dividend or distribution upon the Common
     Stock, (ii) with respect to any pro rata subscription offer to Holder of
     Common Stock, or (iii) for determining rights to vote with respect to any
     Organic Change, dissolution, or liquidation.

          (c) The Company will also give written notice to Holder at least
     twenty (20) days prior to the date on which any Organic Change, Major
     Transaction (as defined below), dissolution, or liquidation will take
     place.

     Section 9. Successors to the Company. The Company shall not consolidate or
merge with or into, or sell all or substantially all of its assets to, any
Person unless: (i) the Person is a corporation; (ii) such Person executes, and
mails to Holder a copy of, an instrument by which such Person or an affiliate
assumes the due and punctual payment of the principal of and interest on this
Series 1 Bridge Note and the performance and observance of all the obligations
of the Company under this Series1 Bridge Note; and (iii) immediately after
giving effect to the transaction, no Event of Default or event which after
notice or lapse of time or both would become an Event of Default shall have
occurred. Upon compliance with this Section 9, Successor Corporation shall
succeed to and be substituted for the Company under this Series 1 Bridge Note
with the same effect as if the Successor Corporation had been named as the
Company herein. Nothing in this Series 1 Bridge Note shall prevent any
consolidation or merger in which the Company is the surviving corporation, or
any acquisition by the Company by purchase or otherwise of all or any part of
the assets of any other Person, and no such consolidation, merger, or
acquisition shall require compliance with this Section 9.

     Section 10. Events of Default and Remedies.

          (a) As used herein, an "Event of Default" occurs if:

               (i) The Company defaults in the payment of principal and/or
          interest when the same becomes due and payable.

               (ii) the Company fails to comply with any other provision
          contained in this Series 1 Bridge Note, the Purchase Agreement, the
          Warrant, the Repricing Warrant, or the Registration Rights Agreement,
          and such failure is not cured within five (5) days after the Company
          receives written demand from Holder to remedy the same;

               (iii) the Company defaults in any payment of principal of or
          interest on any Debt (excluding trade payables) in excess of $100,000
          beyond any period of grace provided with respect thereto and the
          effect of such failure is to cause the holder of such Debt to
          accelerate the Debt such that such Debt becomes due prior to its

     subsequent Event of Default or impair any right consequent thereon.

          (c) A delay or omission by the Holder of this Series 1 Bridge Note in
     exercising any right or remedy arising upon an Event of Default shall not
     impair such right or remedy or constitute a waiver of or an acquiescence in
     the Event of Default.

          (d) If any Event of Default shall occur and be continuing, the Holder
     of this Series 1 Bridge Note may proceed to protect and enforce their
     rights under this Agreement and this Series 1 Bridge Note by exercising
     such remedies as are available to such Holder either by suit in equity or
     by action at law, or both, whether for specific performance of any covenant
     or other agreement contained in this Agreement or in aid of the exercise of
     any power granted in this Agreement. No remedy conferred in this Agreement
     upon Holder is intended to be exclusive of any other remedy, and each and
     every such remedy shall be cumulative and shall be in addition to every
     other remedy conferred herein or now or hereafter existing at law or in
     equity or by statute or otherwise.

     Section 11. Exchange, Transfer, Replacement or Cancellation.

          (a) This Series 1 Bridge Note may be exchanged for an equal principal
     amount of Series 1 Bridge Notes in denominations of US$25,000.00 or in
     greater multiples of US$5,000.00 upon written request to the Company
     accompanied by surrender of this Series 1 Bridge Note to the Company or to
     an agent designated for that purpose. Any Series 1 Bridge Notes issued in
     exchange for this Series 1 Bridge Note shall be one of this Series 1 Bridge
     Note referred to in Section 1, and shall be entitled to all the rights
     thereof.

          (b) The Series 1 Bridge Notes may not be transferred except upon the
     conditions specified in this Section 11(b), which conditions are intended
     to insure compliance with the provisions of the Securities Act of 1933, as
     amended (the "Securities Act"). Prior to any proposed transfer of this
     Series 1 Bridge Note the Holder hereof shall give written notice to the
     Company of the proposed disposition and shall furnish to the Company a
     statement of the circumstances surrounding the proposed disposition and an
     opinion of counsel reasonably satisfactory to the Company to the effect
     that (i) such disposition will not require registration of such securities
     under the Securities Act or qualification of such securities under the blue
     sky or state securities laws of any state in which such qualification would
     be required, or (ii) appropriate action necessary for compliance with the
     Securities Act or the blue sky or securities laws of such states has been
     taken. The Holder hereof shall cause any proposed transferee of such
     securities to agree to take and hold such securities subject to the
     provisions and upon the conditions specified in this Section 11. The
     Company or any co-registrar appointed by the Company may require the Holder
     to furnish appropriate endorsements and/or transfer documents, including
     information regarding any proposed transferee's name, address and social
     security or taxpayer identification number, and to pay any issue or
     transfer taxes or fees as may be required by law. The registered Holder of
     this Series 1 Bridge Note may be treated as its owner for all purposes.

          (c) If Holder claims this Series 1 Bridge Note has been lost,
     destroyed, or wrongfully taken, the Company shall issue a replacement
     Series 1 Bridge Note upon (i) receipt of any indemnity bond or other
     assurance requested by the Company to protect it from any loss which it may
     suffer by reason of such replacement or subsequent presentment of the
     original Series 1 Bridge Note, and (ii) payment of any expenses reasonably
     incurred by the Company in replacing the Series 1 Bridge Note.

     Section 12. Amendments and Waivers. This Series 1 Bridge Note may, with the
consent of the Company and the Holder be amended or any provision thereof
waived.

     Section 13. Notice. Any notice or communication hereunder shall be in
writing and delivered by first-class mail, return receipt requested, to each
Holder at its address shown in the register kept by the

Company or any co-registrar appointed by the Company and to the Company at the
address of its office to be maintained pursuant to Section 2. Failure to mail,
or any defect in, a notice or communication to any other Holder of this Series 1
Bridge Note shall not affect its sufficiency with respect to the other Holders.
If a notice or communication is mailed to Holder in the manner provided above
within the time prescribed, it shall be deemed duly given and effective on the
tenth (10th) business day after it was deposited in the mail, whether or not
Holder actually receives it.

     Section 14. No Recourse Against Others. A director, officer, employee, or
shareholder, as such, of the Company shall not have any liability for any
obligations of the Company under this Series 1 Bridge Note or for any claim
based on, in respect of or by reason of such obligations or their creation. The
Holder of this Series 1 Bridge Note by accepting this Series 1 Bridge Note
waives and releases all such liability and such waiver and release are part of
the consideration for the issue of the Series 1 Bridge Note.

     Section 15. Governing Law. The Series 1 Bridge Notes shall be governed by
and construed in accordance with the laws of the State of New York, irrespective
of the choice of law provisions thereof. The parties agree that any appropriate
state court located in New Castle County, Delaware, or any Federal Court located
in Wilmington, Delaware, including without limitation to the United States
District Court of Delaware, shall have exclusive jurisdiction of any case or
controversy arising under or in connection with this Agreement and shall be a
proper forum in which to adjudicate such case or controversy. The parties
consent to the jurisdiction of such courts.

     IN WITNESS WHEREOF, the parties have caused this Series 1 Bridge Financing
Note to be duly executed as of day and year first above written.
