<PAGE>

         (b)      Section 10.3 is amended in its entirety to read as follows:


                  10.3 Minimum Tangible Net Worth. The Companies' consolidated
         Tangible Net Worth shall not at any time be less than the sum of (a)
         the Base Amount plus (b), for any determination date after December 31,
         2001, an amount equal to seventy five percent (75%) of the Companies'
         consolidated Net Income (without deduction for losses) for each fiscal
         quarter ending after September 30, 2001, and on or before the date of
         determination plus (c) one hundred percent (100%) of the net (i.e.,
         gross less usual and customary brokerage and after related costs and
         expenses) proceeds from the issuance and sale of any equity securities
         by any Company after December 31, 2000, other than the proceeds of any
         issuance and sale of any capital stock which is required to be
         redeemed, or is redeemable at the option of the holder, if certain
         events or conditions occur or exist or otherwise. As used herein, "Base
         Amount" means the sum of (i) Forty Six Million Five Hundred Thousand
         Dollars ($46,500,000) from January 1, 2001 to and including September
         30, 2001, Forty Eight Million Dollars ($48,000,000) from October 1,
         2001 to and including December 31, 2001 and Fifty Three Million Five
         Hundred Thousand Dollars ($53,500,000) thereafter., plus (ii) the
         amount of any deferred tax benefits which will lower future statutory
         tax liability when Borrower reports taxable income if and to the extent
         the independent auditors for Borrower permits Borrower to include such
         deferred tax benefits as an asset on Borrower's balance sheet.

         (c)      Section 10.4 is amended in its entirety to read as follows:

         assets or leaseholds (excluding expenditures properly chargeable to
         repairs or maintenance) for the Companies shall not exceed (a) Six
         Million Dollars ($6,000,000) for the fiscal year ending December 31,
         2000, and, (b) for the fiscal year ending December 31, 2001, the sum of
         Two Million Dollars ($2,000,000) plus up to an additional Two Million
         Dollars ($2,000,000) for capitalized software costs.

3.       Waivers.

         (a) Administrative Agent and Lenders hereby waive any Event of Default
         or Potential Default arising under Section 10.1 of the Credit Agreement
         with respect to the fact that the negative consolidated Operating
         EBITDA for the twelve months ended March 31, 2001 was greater than a
         negative Eight Hundred Fifty Thousand Dollars (-$850,000).

                                                         Ultrak Credit Agreement


<PAGE>


         (b) Administrative Agent and Lenders hereby waive any Event of Default
         or Potential Default arising under Section 10.3 of the Credit Agreement
         with respect to the fact that the Tangible Net Worth as of March 31,
         2001 was less than the required amount.

         (c) Administrative Agent and Lenders hereby grant a temporary,
         revocable waiver (the "Fourth TROL Default Waiver") with respect to the
         Event of Default existing on the date hereof under Section 11.10 of the
         Credit Agreement as a result of the fact that a TROL Default has
         occurred because of the failure of the Companies (i) to maintain as of
         September 30 and December 31, 2000 and March 31, 2001 the leverage
         ratio required by Section 6.01 of the Amended and Restated Guaranty
         dated as of March 22, 2000 given by Parent under the TROL Financing for
         the benefit of the TROL Lenders (the "TROL Guaranty") and the debt
         service coverage ratio required by Section 6.02 of the TROL Guaranty
         and (ii) to maintain as of December 31, 2000 and March 31, 2001 the
         minimum net worth required by Section 6.03 of the TROL Guaranty. The
         Fourth TROL Default Waiver will automatically expire and terminate on
         the earlier of (1) the date on which Administrative Agent or either
         Lender exercises its unconditional revocation right pursuant to the
         next sentence hereof, (2) the date on which the TROL Lenders accelerate
         the maturity of the Lease Obligations (as defined in the TROL Guaranty)
         and (3) the date on which the TROL Lenders commence the exercise of any
         remedies under the TROL Financing Documents. Administrative Agent and
         each Lender hereby reserve the absolute and unconditional right to
         revoke the Fourth TROL Default Waiver at any time, in the sole
         discretion of Administrative Agent or either Lender, with or without
         cause, by giving verbal or written notice of such revocation to
         Borrower, effective immediately at the time such notice is given (with
         any verbal notice to be followed by written notice, but effective as of
         the time of the verbal notice).

4. Conditions Precedent. Unless one or more of the following conditions
precedent is waived by Lenders, this Agreement is effective only if, as and
when:

         (a) Administrative Agent receives counterparts of this Agreement
         executed by Parent, Borrower, Administrative Agent, each Lender and
         each Subsidiary whose name appears on the Subsidiary Joinder at the end

         Administrative Agent and each Lender, including unpaid fees and
         expenses of counsel.

         (c) Borrower delivers to Administrative Agent a certificate of the
         Secretary of Borrower and the Secretary of Parent certifying as to
         resolutions of the board of directors or executive committee of
         Borrower and Parent authorizing and approving the execution of this
         Agreement.

5. Ratifications. Except as expressly modified and superseded by this Agreement,
the Credit Documents are ratified and confirmed and continue in full force and
effect. The Credit Documents, as amended by this Agreement, continue to be
legal, valid, binding and enforceable in accordance

Administrative Agent may reasonably request in order to perfect and protect
those Liens and preserve and protect the Rights of Administrative Agent and

Agreement or any other Credit Document to be delivered under this Agreement, (c)
the execution, delivery and performance by Borrower and the other Companies of
this Agreement and any other Credit Documents to be delivered under this

Borrower or any other Company is a party or by which Borrower or any other
Company is bound, (d) the representations and warranties contained in the Credit
Agreement, as amended by this Agreement, and any other Credit Documents are true

agents, directors, officers, employees, affiliates, accountants, consultants,
contractors, advisors and attorneys (collectively, the "Benefited Parties") from
all Claims (as defined below) and jointly and severally agree to indemnify the
Benefited Parties, and hold them harmless from any and all claims, losses,
causes of action, costs and expenses of every kind or character in connection
with the Claims. As used in this Agreement, the term "Claims" means any and all
possible claims, demands, actions, causes of actions, costs, expenses and
liabilities whatsoever, known or unknown, at law or in equity, originating in

interest in excess of the maximum rate on interest chargeable under applicable
Law and any loss, cost or damage, of any kind or character, arising out of or in
any way connected with or in any way resulting from the actions or omissions of

or similar obligations to Borrower, Parent or any agents, employees or
affiliates of Borrower or Parent and that their relationships are strictly that

each Lender pursuant to this Agreement and shall not be construed as an
admission of liability by Administrative Agent, any Lender or any other
Benefited Party.
