Shared Payment and remit such amount to each Lender, accompanied by computations
in reasonable detail showing the manner of calculation of the amounts
distributable to each Lender pursuant to Section 3.2 hereof.

         3.4      INVALIDATED PAYMENTS.

         If any amount paid by any Lender to the Distribution Agent for
distribution in accordance with the provisions of this Agreement is subsequently
required to be returned or repaid to any of the Subsidiary Guarantors or their
representatives or successors in interest, whether by court order, settlement or
otherwise, such Lender shall promptly notify the Distribution Agent and each
other Lender of such requirement, and request that the Distribution Agent notify
each of the Lenders thereof, and each Lender shall, promptly upon its receipt of
such notice from the Distribution Agent or any other Lender, pay to the
Distribution Agent the pro rata portion received by it of such amount, without
any interest thereon, for payment to the appropriate Subsidiary Guarantors or
their representatives or successors in interest. If any such amounts are

their representatives or successors in interest, such Lender shall remit such
amounts to the Distribution Agent and the Distribution Agent shall redistribute

such amounts were originally distributed. The obligations of the Lenders and the
Distribution Agent under this Section 3.4 shall survive the repayment of the

to receive payments from the Subsidiary Guarantors applicable to the Guarantied

such Receiving Lender shall be paid in full, and for purposes of such
subrogation, no such payment received by such other Lenders shall, as between
the Subsidiary Guarantors or any of them, their respective creditors other than
the holders of any Guarantied Obligations, and the holders of any Guarantied
Obligations, be deemed to be a payment by any of the Subsidiary Guarantors to

EXHIBIT 4.2 Second Amendment to First Common Stock Purchase Warrant of View
Systems, Inc. (Company), Dated February 18, 2000, Issued to Rubin Investment
Group (Holder) and to Subscription and Investment Agreement, dated February 18,
2000, Between Company and Holder

                                  VIEW SYSTEMS, INC.

                                  July 19, 2000

Rubin Investment Group
Attention:  Mr. Dan Rubin

Dear Mr. Rubin:

         This letter refers to the rights of Rubin Investment Group ("RIG") as
to shares of common stock of View Systems, Inc. ("View") currently owned and
which may be acquired by RIG (collectively, the "Initial Shares"). The Initial
Shares consist of 1,065,000 shares currently owned and 2,235,000 shares which
may be acquired by RIG upon the exercise of warrants.

         View has filed a registration statement on Form SB-2 with the
Securities and Exchange Commission to register 853,000 Initial Shares. View
further confirms and agrees that:

              (1) View will file a registration statement on Form SB-2 or other
appropriate form to register 939,000 additional Initial Shares within thirty
(30) days after written demand is given to View by RIG to register any
additional Initial Shares; and

              (2) View will file a second registration statement on Form SB-2 or
other appropriate form to register all remaining Initial Shares then owned by
RIG within thirty (30) days after a second written demand is given to View by
RIG to register additional Initial Shares.

         In the event RIG makes a written demand to register Initial Shares but
does not directly own the number of Initial Shares covered by the registration
statement filed by View hereunder, RIG will exercise its warrants within 30 days
after the effective date of the registration statement so that it owns directly
that number of Initial Shares covered by the registration statement. The demand
registration rights provided in this letter shall expire on December 31, 2001.

         View further agrees that the warrants currently owned by RIG are hereby
amended to extend the exercise period to the 30th day following the effective
date of a second registration statement filed by View pursuant to a second
demand by RIG to register Initial Shares.

         If the following accurately reflects our agreement, please sign in the
space below.

                                  Sincerely,
                                  VIEW SYSTEMS, INC.

                                  By:/s/ Gunther Than
                                     ------------------------
                                     Gunther Than, President

ACCEPTED AND AGREED
Rubin Investment Group
