EXHIBIT 10.20(a)

                       AMENDMENT TO FORBEARANCE AGREEMENT
                       AND PAYMENT OF INTEREST WITH STOCK
   CAN-CAL RESOURCES LTD. AND FIRST COLONY MERCHANT AND TOBIAN TRADING LIMITED

                                January 29, 2002

     This Amendment is entered into between Can-Cal Resources Ltd. (the
"Borrower") and First Colony Merchant and Tobian Trading Limited (collectively
the "Lender").

     Whereas, the Lender loaned Borrower $300,000 on or about November 23, 2000
under a Loan Agreement, requiring interest to be paid semiannually on May 24 and
November 24 of each year; and

     Whereas, the Borrower did not pay the interest due on May 24, 2001 and as a
result, the Lender and the Borrower entered into a Forbearance Agreement on
August 7, 2001, under which the May 24, 2001 interest due of $24,000 was added
to the principal amount of the loan, and said $24,000 was to be paid on or
before November 24, 2001; and

     Whereas, as of the date of this Amendment, the Borrower has not paid either
the $24,000 of interest originally due May 24, 2001 but by the Forbearance
Agreement deferred to November 24, 2001, or the $24,000 of interest due November
24, 2001;

     The  Lender and the Borrower agree:

     1.   The $48,000 of interest due to be paid by the Borrower to the Lender
          on or before November 24, 2001, is by this Amendment signed by
          Borrower and Lender, paid in full by the Borrower agreeing to issue
          309,677 shares of restricted common stock to the Lender, determined in
          the same manner as section 3 b of the Forbearance Agreement: A
          purchase price per share of $0.155, being 50% of the lowest trading
          price for the Borrower's common stock as published by Yahoo! Finance
          Historical Quote during the period from November 23, 2000 through
          Friday, December 31, 2001 ($0.31 x 50% = $0.155). The Borrower shall
          instruct its stock transfer agent to deliver the stock certificate for
          the shares to the Lender, in the name of the Lender or Tobian Trading,
          as requested by the Lender, as soon as possible.

     2.   Except as amended by section 1 above, the Forbearance Agreement, and
          the original Loan Agreement, remain in full force and effect.

     Signed in Las Vegas, Nevada.

               FINANCIAL ADVISORY AND INVESTMENT BANKING AGREEMENT

         This Agreement is made and entered as of December 1, 2001 between
EarlyBirdCapital, Inc. ("EBC" or the "Consultant") and Network-1 Security
Solutions, Inc. (the "Company").

         In consideration of the mutual promises made herein and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1.  The Company hereby engages the Consultant to render financial
consulting and investment banking advice to the Company upon the terms and
conditions set forth herein. The term of this Agreement shall be for 12 months
commencing on December 1, 2001. This engagement of Consultant by the Company
shall be on a non-exclusive basis and shall not prevent the Company from
engaging another party to act in the same or similar capacity.

         2.  During the term of this Agreement, Consultant shall provide the
Company with such regular and customary financial consulting advice as is
reasonably requested by the Company. It is understood and acknowledged by the
parties that the value of Consultant's advice is not readily quantifiable, and
that although Consultant shall be obligated to render the advice contemplated by
this Agreement upon the reasonable request of the Company, Consultant shall not
be obligated to spend any specific amount of time in so doing. Consultant's
duties may include, but will not necessarily be limited to:

             (a) Assisting in the Company's financial public relations;

             (b) Rendering advice with regard to internal operations, including:
                 (i)   the formation of corporate goals and their
                       implementation;
                 (ii)  the Company's financial structure and its divisions or
                       subsidiaries;
                 (iii) securing, when and if necessary and possible, additional
                       financing through banks and/or insurance companies; and
                 (iv)  corporate organization and personnel.

             (c) Rendering advice with regard to any of the following corporate
                 finance matters:
                 (i)   changes in the capitalization of the Company;
                 (ii)  changes in the Company's corporate structure;
                 (iii) redistribution of shareholdings of the Company's stock;
                 (iv)  offerings of securities in public and private
                       transactions;
                 (v)   alternative uses of corporate assets;
                 (vi)  structure and use of debt; and
                 (vii) sales of stock by insiders pursuant to Rule 144 or
                       otherwise.

             In addition to the foregoing, Consultant shall also render such
other financial consulting and/or investment banking services (including mergers
and acquisitions or financings of the Company) as may from time to time be
agreed upon by Consultant and the Company.

             Consultant may engage other companies to furnish certain of the
consulting services provided for hereunder, subject to consultant's supervision,
and remit a portion of its compensation to these companies in exchange for these
services, provided, however, that this arrangement shall not increase the total
compensation that must be paid by the Company under this Agreement.

         3.  The Company shall pay Consultant the following compensation:

             (a) A cash fee of $200,000, of which $35,000 shall be payable upon
signing this Agreement and the balance of $165,000 shall be payable as follows:
(i) nine monthly installments of $10,000 on the first day of each calendar month

each, payable on May 31, 2002, August 31, 2002 and November 30, 2002.

             (b) In addition to the above, upon the written request of the

compensate Consultant in amounts to be mutually agreed upon, in the event that:

                 (i)   Consultant originates a financing;
                 (ii)  Consultant acts as an underwriter or placement agent in
                       the sale or distribution of securities by the Company to
                       the public or in a private transaction;
                 (iii) Consultant provides a fairness opinion or other valuation
                       analysis; or
                 (iv)  Consultant introduces to the Company a source for
                       business from which the Company derives revenue.

         4.  (a) The Company acknowledges that all opinions and advice (written
or oral) given by Consultant to the Company in connection with Consultant's
engagement are intended solely for the benefit and use of the Company in
considering the transaction to which they relate, and the Company agrees that no
person or entity other than the Company shall be entitled to make use of or rely
upon the advice of Consultant to be given hereunder, and no such opinion or
advice shall be used for any manner or for any purpose, nor may the Company make
any public references to Consultant, or use the Consultant's name in any annual
reports or any other reports or releases of the Company, without Consultant's
prior written consent.

             (b) The Company acknowledges that Consultant makes no commitment to
make a market in the Company's securities, to recommend or advise its clients to
purchase the Company's securities, or to prepare research or corporate finance
reports.

         5.  Consultant will hold in confidence any confidential information
which the Company provides to Consultant pursuant to this Agreement which is
designated by an appropriate stamp or legend as being confidential.
Notwithstanding the foregoing, Consultant shall not be required to maintain
confidentiality with respect to information (i) which is or becomes part of the
public domain not due to the breach of this Agreement by Consultant; (ii) of
which it had independent knowledge prior to disclosure; (iii) which comes into
the possession of Consultant in the normal and routine course of its own
business from and through independent non-confidential sources; or (iv) which is
required to be disclosed by Consultant by laws, rules or regulations. If
Consultant is requested or required to disclose any confidential information
supplied to it by the Company, Consultant shall, unless prohibited by law,
promptly notify the Company of such request(s) so that the Company may seek an
appropriate protective order.

         6.  Consultant shall perform its services hereunder as an independent
contractor and not as an employee or agent of the Company or any affiliate
thereof. Consultant shall have no authority to act for, represent or bind the
Company or any affiliate thereof in any manner, except as may be expressly
agreed to by the Company in writing from time to time.

         7.  This Agreement constitutes the entire agreement between the parties
with respect to the subject matter hereof. No provision of this Agreement may be
amended, modified or waived, except in a

                                        2

to the benefit of each of the parties and their respective successors, legal
representatives and assigns. This Agreement may be executed in counterparts. In
the event of any dispute under this Agreement, then and in such event, each

in accordance with its rules and regulations then in effect. Each of the parties
agrees that the decision and/or award made by the AAA may be entered as judgment
of the Courts or the State of New York, and shall be enforceable as such. This
Agreement shall be construed and enforced in accordance with the laws of the
