     THIS NINTH AMENDMENT TO LOAN AND SECURITY AGREEMENT AND
FIRST NOTE MODIFICATION AGREEMENT (this "Amendment") is made and
entered into as of July 23, 1997, by and among TELTRONICS, INC.,
a Delaware corporation (hereinafter referred to as "Teltronics"),
with its chief executive office and principal place of business
at 2150 Whitfield Industrial Way, Sarasota, Florida 34243; AT

and principal place of business at 4706 Shavano Oak, Suite 104,

and principal place of business at 2150 Whitfield Industrial Way,

INC., a Delaware corporation (hereinafter referred to as

York, New York 10036.

                            RECITALS:

     Lender, Teltronics and ATS are parties to a certain Loan and
Security Agreement dated October 28, 1994, as amended by a
certain letter agreement dated December 27, 1994, a certain
Second Amendment to Loan and Security Agreement dated as of
December 29, 1995, a certain letter agreement dated March 11,
1996, a certain letter agreement dated May 14, 1996, a certain
letter agreement dated June 4, 1996, a certain letter agreement
dated July 31, 1996, a certain Seventh Amendment to Loan and
Security Agreement dated January 13, 1997 and a certain Eighth
Amendment to Loan and Security Agreement dated February 11, 1997
(as at any time amended, the "Loan Agreement"), pursuant to which
Lender has made revolving credit and term loans to Borrowers.

     On October 18, 1996, Borrowers executed a certain Secured
Promissory Note in favor of Lender in the original principal
amount of $616,300 (the "Term Note") to evidence a term loan made
by Lender to Borrowers.

     In order to utilize the financial powers of Borrowers in the
most efficient and economic manner and as a matter of
administrative convenience, Teltronics, ATS and Interactive
desire that Interactive become a party to the Loan Agreement and
that Lender make revolving loans thereunder to Borrowers based
upon the value of the assets of Borrowers.

     Borrowers' business is a mutual and collective enterprise
and Borrowers believe that the consolidation of all loans and
other financial accommodations under the Loan Agreement will
enhance the aggregate borrowing powers of Borrowers and ease the
administration of their loan relationships with Lender, all to
the mutual advantage of Borrowers.

     As an accommodation to Borrowers and at Borrowers' request
in furtherance of Borrowers' mutual and collective enterprise,
Lender is willing to extend credit to Borrowers and to administer
Borrowers' collateral security therefor on a combined basis in
accordance with the terms of the Loan Agreement as amended
hereby.

     The parties now desire to further amend the Loan Agreement
and to modify the Term Note as hereinafter set forth.

     NOW, THEREFORE, for and in consideration of TEN DOLLARS
($10.00) in hand paid and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound hereby, agree as
follows:

          1.   DEFINITIONS.  All capitalized terms used in this
Amendment, unless otherwise defined herein, shall have the
meaning ascribed to such terms in the Loan Agreement.

          2.   ASSUMPTION OF LOANS.  In consideration of Lender's
consent to Interactive becoming a party to the Loan Agreement,
Interactive assumes and agrees to be jointly and severally liable
with Teltronics and ATS for all Revolving Loans and the Term Loan
outstanding on the date of this Agreement and hereafter
outstanding from time to time under the Loan Agreement, together
with all fees, expenses and other charges payable in the
collection thereof or otherwise in connection therewith.

          3.   CO-BORROWING ARRANGEMENT.  Borrowers acknowledge
that they have requested Lender to extend financial
accommodations to them, on a combined basis, in accordance with
the provisions of the Loan Agreement as hereby amended. 
Borrowers shall be jointly and severally liable for the payment
of the Term Loan and all Revolving Loans heretofore or hereafter
made by Lender under the Loan Agreement and all interest, fees
and other charges payable in connection with the Term Loan and
the Revolving Loans.  A request by Teltronics for a Revolving
Loan shall be deemed to be a request for a Revolving Loan by each
Borrower, and each shall be an agent for the other for such
purposes, and each Revolving Loan made by Lender under the Loan
Agreement, whether or not advanced to a bank account in the name
of only one of them, shall be deemed to be for the account and
mutual benefit of each of them. Interactive hereby appoints
Teltronics as, and Teltronics shall act under the Loan Agreement
as, the representative of Interactive for all purposes, including
requesting borrowings and receiving account statements and other
notices and communications to Borrowers (or any of them) from
Lender.  Lender may rely, and shall be fully protected in relying
on any request for borrowing, disbursement instructions, reports,
information or any other notice or communication made or given by
Teltronics, whether in its own name, on behalf of Interactive or
on behalf of the "Borrowers" and Lender shall have no obligation
to make any inquiry or request any confirmation from or on behalf
of Interactive as to the binding effect on Interactive of any
such request, instruction, report, information, notice or
communication, nor shall the joint and several character of
Borrowers' liability for the Obligations be affected.  Each loan
made by Lender shall be disbursed to the loan account of the
Borrower for whom such loan was requested, and each Borrower
confirms that such arrangement shall have no effect on the joint
and several character of their liability for the Obligations to
the extent provided herein and in the Loan Agreement.

          4.   CONFORMING GLOBAL AMENDMENTS.  The Loan Agreement
is hereby amended to effect the following conforming global
amendments:
     
          (a)  All references to "Borrower" shall mean each of 
Teltronics, ATS and Interactive, or any of them; 

          (b)  All references to Eligible Accounts or Eligible
Inventory shall be understood to mean and include any accounts of
Teltronics, ATS or Interactive that meet the criteria for
Eligible Accounts pursuant to subsection 2.1(d) of the Loan
Agreement and any inventory of Teltronics, ATS or Interactive
that meets the criteria for Eligible Inventory under subsection
2.1(e) of the Loan Agreement; and 

          (c)  Any requirement for the giving by Lender of any
notice to Borrowers shall be deemed fully complied with and
discharged by the giving of such notice to Teltronics, and notice
to Teltronics shall be deemed to constitute an effective notice
to all.

          5.   SPECIFIC AMENDMENTS TO LOAN AGREEMENT.  The Loan
Agreement is hereby amended as follows:

          (a)  By adding the following new Section 1.5 to the
Loan Agreement:

               1.5. "INTERACTIVE" means Interactive Solutions,
     Inc., a Delaware corporation, and its successors and
     assigns.

          (b)  By deleting Section 9.1 of the Loan Agreement in
its entirety and by substituting the following new Section 9.1 in
lieu thereof:

          9.1  This Agreement shall continue in full force
     and effect until October 28, 2000 (the "INITIAL TERM")
     and shall be deemed automatically renewed for
     successive terms of two (2) years each thereafter (each
     a "RENEWAL TERM") unless terminated as of the end of
     the Initial Term or any Renewal Term by either party
     giving the other written notice at least sixty (60)

     early termination fee provided below.  Lender shall
     also have the right to terminate this Agreement at any
     time upon or after the occurrence of an Event of
     Default.  If Lender terminates this Agreement upon or
     after the occurrence of an Event of Default, or if
     Borrowers shall terminate this Agreement as permitted
     herein effective prior to the end of the Initial Term
     or any Renewal Term, as applicable, in addition to all
     other Obligations, Borrowers jointly and severally
     shall pay to Lender, upon the effective date of
     termination, in view of the impracticality and extreme
     difficulty of ascertaining actual damages and by mutual
     agreement of the parties as to a reasonable calculation
     of Lender's lost profits, an early termination fee
     equal to (a) four percent (4%) of the Maximum Credit if
     termination occurs at any time prior to October 28,
     1995, (b) two percent (2%) of the Maximum Credit if
     termination occurs during the period from October 28,
     1995 through October 28, 1996; (c) one and one-half
     percent (1.5%) of the Maximum Credit if termination
     occurs during the period from October 29, 1996 through
     October 28, 1998; and (d) one percent (1.0%) of the
     Maximum Credit if termination occurs at any time after
     October 28, 1998.
          
          (d)  By deleting Sections 9.12 and 9.13 of the Loan
Agreement in their entireties and by substituting the following
new Sections 9.12 and 9.13 in lieu thereof:

               9.12. JOINT AND SEVERAL LIABILITY.

               (a)  JOINT AND SEVERAL LIABILITY.  All of the
     Obligations shall constitute the joint and several,
     direct and general obligation of each Borrower, and
     Borrowers shall be jointly and severally, directly and
     unconditionally liable to Lender for all of the
     Obligations, it being agreed that the advances to any
     of Teltronics, ATS or Interactive inure to the benefit
     of each Borrower, and that the Lender is relying on the
     joint and several liability of Borrowers in extending
     Revolving Loans and other financial accommodations
     hereunder.  Teltronics, ATS and Interactive each hereby
     unconditionally and irrevocably agrees that upon
     default in the payment when due (whether at stated
     maturity, by acceleration or otherwise) of any
     principal of, or interest owed on, any Revolving Loan
     or other Obligation payable to Lender, it will
     forthwith pay the same, without notice or demand.  

               (b)  NO REDUCTION IN OBLIGATIONS.  No payment
     or payments made by Teltronics, ATS or Interactive or
     any other Person or received or collected by Lender
     from Teltronics, ATS or Interactive or any other Person
     by virtue of any action or proceeding or any setoff or
     appropriation or application at any time or from time
     to time in reduction of or in payment of the
     Obligations shall be deemed to modify, reduce, release
     or otherwise affect the liability of Teltronics, ATS or
     Interactive under this Agreement, each of whom shall
     remain jointly and severally liable for the payment of
     all of the Obligations until paid in full and this
     Agreement is terminated.

               9.13.  WAIVER OF SURETYSHIP DEFENSES. 
     Teltronics, ATS and Interactive each agree that the
     joint and several liability of Borrowers provided for
     in subsection 9.12 of this Agreement shall not be
     impaired or affected by any modification, supplement,
     extension or amendment or any contract or agreement to
     which Teltronics, ATS or Interactive may hereafter
     agree (other than an agreement signed by the Lender
     specifically releasing such liability), nor by any
     delay, extension of time for the payment of, renewal,
     compromise or other indulgence granted by Lender with
     respect to any of the Obligations, nor by any release
     of subordination of any Lien with respect to any or all
     of the Collateral other agreements or arrangements
     whatever with the other or with anyone else, each
     hereby waiving all notices of such delay, extension,
     release, substitution, renewal, compromise or other
     indulgence, and hereby consenting to be bound thereby
     as fully and effectually as if it had expressly agreed
     thereto in advance.  The liability of Teltronics, ATS
     and Interactive is direct and unconditional as to all
     of the Obligations, and may be enforced without
     requiring Lender first to resort to any other right,
     remedy or security.  Teltronics, ATS and Interactive
     each expressly waives promptness, diligence, notice of
     acceptance and any other notice with respect to any of
     the Obligations, this Agreement or any other loan
     documents and any requirement that Lender protect,
     secure, perfect or insure any Lien or any property
     subject thereto or exhaust any right or take any action
     against Teltronics, ATS, Interactive or any Person or
     any Collateral.
    
          (c)  By deleting Section 10.1(a) of the Loan Agreement
and by substituting the following new Section 10.1(a) in lieu
thereof:

          10.1(a) Maximum Credit:  $7,000,000

          (d)  By inserting the following new text immediately
after Section 10.1(e) and immediately preceding Section 10.2:

     In the event that Teltronics sells all of the
     outstanding capital stock of ATS owned by Teltronics,
     or sells all or substantially all of the assets of ATS,
     on or before  July 23, 1998, then Teltronics and
     Interactive may (without incurring any additional
     premiums or fees) elect to reduce the Maximum Credit
     under Section 10.1(a) from $7,000,000 to $5,500,000. If
     such reduction in the Maximum Credit occurs, then the
     Minimum Borrowing under Section 10.1(e) shall be
     reduced from $4,000,000 to $3,500,000.

          (e)  By deleting Sections 10.4(a),(b),(c) and (d) of
the Loan Agreement in their entirety and by substituting the
following new Sections 10.4(a),(b), (c) and (d) in lieu thereof:

          (a)  Interest Rate:  A variable rate per
               annum equal to the Prime Rate in
               effect from time to time plus two
               and one-half percent (2.5%) per
               annum; provided, however that
               effective August 1, 1997, the
               interest rate hereunder shall be a
               variable rate per annum equal to
               the Prime Rate plus two percent
               (2%) per annum.  The Prime Rate in
               effect on July 23, 1997, is 8.5%
               and therefore the Interest Rate in
               effect on and as of July 23, 1997,
               expressed in simple interest terms,
               is 11.0%. 

          (b)  Facility Fee:

               (i)  INITIAL TERM. In
                    consideration of Lender's
                    willingness to make
                    advances to Borrowers
                    from time to time under
                    the credit facility,
                    Borrowers jointly and
                    severally shall pay to
                    Lender, a fee in the
                    amount of $70,000 for
                    each year during the
                    Initial Term, which fees
                    shall be fully earned
                    upon execution and
                    delivery of the Ninth
                    Amendment to Loan and
                    Security Agreement by
                    Borrowers, and shall be
                    payable on October 28,
                    1997 and each subsequent

          (ii) Renewal Terms. If the Maximum
               Credit is renewed after the Initial
               Term, then Borrowers jointly and
               severally shall pay to Lender an
               additional Facility Fee of $70,000
               for each year during such Renewal
               Term, which fees shall be fully
               earned on the first day of each
               such Renewal Term and shall be
               payable on the first day of each
               such Renewal Term and on the first
               anniversary of each such Renewal
               Term. 

          (c)  Minimum Loan Fee:  If the average
               outstanding amount of the loans
               (including all Revolving Loans and
               any Term Loan) in any Loan Year (as
               defined below) is less than
               $4,000,000, then Lender shall be
               entitled to receive a fee, payable
               as of the last day of each Loan
               Year, equal to the difference
               between $4,000,000 and the actual
               annual average daily loan balance
               for the Loan Year in question,
               multiplied by the Interest Rate in
               effect on the last day of the Loan
               Year in question.  As used herein,
               the term "Loan Year" shall mean a
               year beginning on November 1 of a
               year in which this Agreement is in
               effect and ending on October 31st
               of the next year.

          (d)  Unused Line Fee:  .5% per annum
               payable monthly, in arrears, on the
               first day of each month, based upon
               the difference between (i) the
               Maximum Credit and (ii) the greater
               of (A) the Minimum Borrowing in
               effect at the date of determination
               or (B) the Average Monthly Loan
               Balance each month (including all
               Revolving Loans and any Term Loan). 
               For purposes hereof, "Average
               Monthly Loan Balance" shall mean,
               for any month, the amount obtained
               by adding the unpaid balance of all

               owing by Borrowers to Lender at the
               end of each day during the month in
               question and by dividing such sum
               by the number of days in such month
               that the credit facility is in
               effect.
