[LOGO] CHASE                                            THE CHASE MANHATTAN BANK

                                MASTER GRID NOTE

$2,000,000.00                                                     Plainview N.Y.
                                                                    July 1, 1999

      On the due date for each Advance or on Demand (as recorded on the grid
attached hereto or on any additional pages thereof), but in any event on June
30, 2000 if outstanding on such date, for value received, the undersigned
hereby promises to pay to the order of THE CHASE MANHATTAN BANK (hereinafter
the "Bank") at its offices at 7600 Jericho Tpke., Woodbury, New York, the
principal sum of the aggregate unpaid principal amount of each Advance (as
recorded on the grid attached hereto or on any additional pages thereof) made
by the Bank to the undersigned. The undersigned further promises to pay
interest on the unpaid principal amount of each Advance (computed on the
basis of the actual number of days elapsed on the basis of a 360-day year) on
7/31 (specific date) and the last day of each month (insert "month", "third
month", "quarter", etc.) thereafter, and at maturity, at the per annum rate
of interest recorded for such Advance on the grid attached hereto or on any
additional page thereof, but in no event higher than the maximum interest
rate permitted under applicable law. Advances for which the designated rate
of interest is or includes "Prime Rate", "Prime", "P" or similar designations
(e.g., "P + 1%") shall be read to refer to a floating rate equaling or based
upon the Bank's Prime Rate, and shall be adjusted on the date of each change
thereof. Prime Rate shall be the rate of interest as is publicly announced at
the Bank's principal office from time to time as its prime rate. Interest on
any past due amount, whether at the due date thereof or by acceleration,
shall be paid at a rate of three percent (3%) per annum in excess of the
above stated rate, but in no event higher than the maximum permitted under
applicable law. Time for payment extended by law shall be included in the
computation of interest.

      If any principal of any Advance hereunder which bears interest at a fixed
rate of interest is paid prior to the scheduled maturity date set forth on the
grid attached hereto or on any additional pages thereof (whether by
acceleration, prepayment or otherwise), the undersigned also agrees to pay to
the Bank, on demand, such amount as is reasonably determined by the Bank to
represent the aggregate losses, costs, and expenses incurred or suffered by the
Bank as a result of such payment (including losses, costs and expenses resulting
from not receiving the rate of interest set forth above for the entire loan
period and/or the liquidation or redeployment of funds). A certificate of the
Bank setting forth the foregoing amount shall, absent manifest error, be
conclusive and binding for all purposes.

      The undersigned hereby grants to the Bank a lien on, security interest in
and right of set-off against all monies, securities and other property of the
undersigned and the proceeds thereof now or hereafter delivered to remain with
or in transit in any manner to the Bank, its correspondents or its agents from
or for the undersigned, whether for safekeeping, custody, pledge, transmission,
collection or for any other purpose, or coming into possession, control or
custody of the Bank, Chase Securities Inc., or any other affiliate of the Bank
in any way, and, also, any balance of any deposit account and credits of the
undersigned with, and any other claims of the undersigned against, the Bank,
Chase Securities Inc., or any other affiliate of the
<PAGE>

Bank at any time existing (all of which are hereinafter collectively called
"Collateral"), as collateral security for the payment of this note and all other
liabilities and obligations now or hereafter owed by the undersigned to the
Bank, contracted with or acquired by the Bank, whether joint, several, direct,
indirect, absolute, contingent, secured, unsecured, matured or unmatured (all of
which are hereafter collectively called "Liabilities"), hereby authorizing the
Bank at any time or times, without notice or demand, to apply any such
Collateral or any proceeds thereof to any of such Liabilities in such amounts as
it in its sole discretion may select, whether contingent, unmatured or otherwise
and whether any other collateral security therefor is deemed adequate or not.
The undersigned authorizes the Bank to deliver to others a copy of this note as
written notification of the undersigned's transfer of a security interest in the
Collateral. The Bank further is authorized at any time or times, without demand
or notice to the undersigned, to transfer to or register in the name of its
nominee or nominees all or any part of the Collateral and to exercise any and
all rights, power and privileges (except that prior to an Event of Default the
Bank shall not have the right to vote or to direct the voting of any
Collateral). The collateral security and other rights described herein shall be
in addition to any other collateral security described in any separate agreement
executed by the undersigned.

      In the event of: default in the prompt payment of any Liabilities; default
in any other indebtedness of the undersigned (which, for the purposes of this
sentence, means the undersigned or any guarantor, surety or endorser of, or any
person or entity which has pledged any of its property to secure, any
Liabilities); complete or partial liquidation or suspension of any business of
the undersigned; dissolution, merger, consolidation or reorganization of the
undersigned; death of or loss of employment by an individual or any member of
any partnership (if the undersigned is an individual or a partnership); failure
to furnish any financial information or to permit inspection of any books or
records at the Bank's request; a representation, warranty or statement of the
undersigned proving false in any material respect when made or furnished;
general assignment for the benefit of creditors or insolvency of the
undersigned; commencement of any proceeding supplementary to any execution
relating to any judgment against the undersigned; attachment; distraint, levy,
execution or final judgment against the undersigned or against the property of
the undersigned; assignment by the undersigned of any equity in any of the
Collateral without the written consent of the Bank; appointment of a receiver,
conservator, rehabilitator or similar officer for the undersigned, or for any
property of the undersigned; tax assessment by the United States Government or
any state or political subdivision thereof against the undersigned; the taking
of possession of, or assumption of control over, all or any substantial part of
the property of the undersigned by the United States Government, or any state or
political subdivision thereof, foreign government (de facto or de jure)or any
agency of any thereof; calling of a meeting of creditors, assignment for the
benefit of creditors or bulk sale or notice thereof; any mortgage, pledge of or
creation of a security interest in any assets without the consent of the holder
of this note; filing of a petition in bankruptcy, commencement of any proceeding
under any bankruptcy or debtor's law (or similar law analogous in purpose or
effect) for the relief, reorganization, composition, extension, arrangement or
readjustment of any of the obligations by or against the undersigned; then, and
in any of those events (each, an "Event of Default"), all Liabilities, although
otherwise unmatured or contingent, shall forthwith become due and payable
without notice or demand and notwithstanding anything to the contrary contained
herein or in any other instrument. Further, acceptance of any payments shall not
waive or affect any prior demand or acceleration of these Liabilities, and each
such payment made shall be applied first to the payment of accrued interest,
then to the aggregate unpaid

                                       2
<PAGE>

principal or otherwise as determined by the Bank in its sole discretion. The
undersigned hereby irrevocably consents to the in personam jurisdiction of the
federal and/or state courts located within the State of New York over
controversies arising from or relating to this note or the Liabilities and
irrevocably waives trial by jury and the right to interpose any counterclaim or
offset of any nature in any such litigation. The undersigned further irrevocably
waives presentment, demand, protest, notice of dishonor and all other notices or
demands of any kind in connection with this note or any Liabilities. The
undersigned shall be jointly and severally liable hereon.

      The Bank may, at its option, at any time when in the judgment of the Bank
the Collateral is inadequate or the Bank deems itself insecure, or upon or at
any time after the occurrence of an Event of Default, proceed to enforce payment
of the same and exercise any of or all the rights and remedies afforded the Bank
by the Uniform Commercial Code (the "Code") or otherwise possessed by the Bank.
Any requirement of the Code for reasonable notice to the undersigned shall be
deemed to have been complied with if such notice is mailed, postage prepaid, to
the undersigned and such other persons entitled to notice, at the addresses
shown on the records of the Bank at least four (4) days prior to the time of
sale, disposition or other event requiring notice under the Code.

      The undersigned agrees to pay to the Bank, as soon as incurred, all costs
and expenses incidental to the care, preservation, processing, sale or
collection of or realization upon any of or all the Collateral or incurred in
connection with the enforcement or collection of this note, or in any way
relating to the rights of the Bank hereunder, including reasonable inside or
outside counsel fees and expenses. Each and every right and remedy hereby
granted to the Bank or allowed to it by law shall be cumulative and not
exclusive and each may be exercised by the Bank from time to time and as often
as may be necessary. The undersigned shall have the sole responsibility for
notifying the Bank in writing that the undersigned wishes to take advantage of
any redemption, conversion or other similar right with respect to any of the
Collateral. The Bank may release any party (including any partner of any
undersigned) without notice to any of the undersigned, whether as co-makers,
endorsers, guarantors, sureties, assigns or otherwise, without affecting the
liability of any of the undersigned hereof or any partner of any undersigned
hereof.

      Upon any transfer of this note, the undersigned hereby waiving notice of
any such transfer, the Bank may deliver the Collateral or any part thereof to
the transferee who shall thereupon become vested with all the rights herein or
under applicable law given to the Bank with respect thereto and the Bank shall
thereafter forever be relieved and fully discharged from any liability or
responsibility in the matter; but the Bank shall retain all rights hereby given
to it with respect to any Liabilities and Collateral not so transferred. No
modification or waiver of any of the provisions of this note shall be effective
unless in writing, signed by the Bank, and only to the extent therein set forth;
nor shall any such waiver be applicable except in the specific instance for
which given. This agreement sets forth the entire understanding of the parties,
and the undersigned acknowledges that no oral or other agreements, conditions,
promises, understandings, representations or warranties exist in regard to the
obligations hereunder, except those specifically set forth herein.

      If the undersigned is a partnership, the agreement herein contained shall
remain in force and applicable, notwithstanding any changes in the individuals
composing the partnership or any

                                       3

release of any partner or partners and their partners shall not thereby be
released from any liability. If this note is signed by more than one party, the
terms "undersigned", as used herein, shall include and mean the "undersigned and
each of them" and each undertaking herein contained shall be their joint and
several undertaking, provided, however, that in the phrases "of the
undersigned", "by the undersigned", "against the undersigned", "for the
undersigned", "to the undersigned", and "on the undersigned", the term
"undersigned" shall mean the "undersigned or any of them", and the Bank may
release or exchange any of the Collateral belonging to any of the parties hereto
and it may renew or extend any of the liabilities of any of them and may make
additional advances or extensions of credit to any of them or release or fail to
set off any deposit account or credit to any of them or grant other indulgences
to any of them, all from time to time, before or after maturity hereof, with or
without further notice to or assent from any of the other parties hereto. Each
reference herein to the Bank shall be deemed to include its successors,
endorsees, and assigns, in whose favor the provisions hereof shall also inure.
Each reference herein to the undersigned shall be deemed to include the heirs,
executors, administrators, legal representatives, successors and assigns of the
undersigned, all of whom shall be bound by the provisions hereof.

      The provisions of this note shall be construed and interpreted and all

Mr. Alvin Ring
President

Plainview, New York 11803

Dear Al,

I am pleased to inform you that The Chase Manhattan Bank ("Chase") has approved
a $2,000,000 secured line of credit in favor of Real Time Strategies, Inc. (the
"Borrower") to be used for normal short term working capital needs, subject to
the terms set forth in this letter.

Any advances which Chase may extend will be on the terms and conditions as we
may require at the time the Borrower requests an advance and must be evidenced
by documents in form and substance satisfactory to Chase.

All outstanding borrowings under this arrangement will bear interest at Chase's
Prime Rate plus one percent (Prime +1%) in effect from time to time and shall be
evidenced by documentation in form and substance satisfactory to Chase.

To compensate Chase for the cost of its ongoing credit review, an annual fee of
2,500 per annum will be charged against the total line of credit.

This line of credit shall be further subject to the requirement that for 30
consecutive days during each twelve month period or during the term hereof,
whichever is shorter, there shall be no loans outstanding hereunder.

This line of credit shall expire on June 30, 2000, unless terminated earlier by
Chase in its sole discretion. This letter does not constitute a commitment or in
any way obligate Chase to lend. This letter constitutes the entire understanding
between Chase and the Borrower on this subject.
<PAGE>

Please acknowledge your understanding of the foregoing by signing and returning
the enclosed copy of this letter along with the pro-rated origination fee to the
undersigned no later than August 1, 1999.

We appreciate the opportunity to be of service to you.

Very truly yours,

THE CHASE MANHATTAN BANK
