                     AMENDED AND RESTATED CREDIT AGREEMENT


         THIS AMENDED AND RESTATED CREDIT AGREEMENT (this "AGREEMENT") is
entered into as of March 22, 2000 among ULTRAK OPERATING, L.P., a Texas limited
partnership ("BORROWER"), ULTRAK, INC., a Delaware corporation ("PARENT"),
AMERICAN NATIONAL BANK AND TRUST COMPANY OF CHICAGO, as LENDER (defined below),
and AMERICAN NATIONAL BANK AND TRUST COMPANY OF CHICAGO, as ADMINISTRATIVE AGENT
(defined herein) for itself and future Lenders.


                              PRELIMINARY STATEMENT

         A. Parent is a U.S.-based multinational corporation with domestic and
foreign subsidiaries that design, manufacture, market, sell and service
electronic products and systems for use in security and surveillance, industrial
and medical video and professional audio markets worldwide. Ultrak Operating,
L.P., the "Borrower" under this Agreement, is the principal domestic operating
subsidiary of Parent.

         B. Parent (as borrower), Bank One, Texas, N.A. ("BANK ONE") (as agent
and lender) and Wells Fargo Bank (Texas), National Association ("WELLS FARGO")
(as lender) (Bank One and Wells Fargo being herein called the "PRIOR LENDERS")
were parties to the Prior Credit Agreement (defined herein) whereby Prior
Lenders extended credit to Parent to provide for, among other things, (i) a term
loan facility in the aggregate principal amount of Twenty Million Dollars
($20,000,000), and (ii) a revolving loan and standby letter of credit facility
in the aggregate principal amount of up to Thirty Million Dollars ($30,000,000).

         C. The "Obligation", as defined in the Prior Credit Agreement, is
herein called the "PRIOR OBLIGATION". Immediately prior to the Closing Time
under this Agreement, Parent will pay to Prior Lenders all non-principal amounts
due and owing on the Prior Obligation, leaving a "Principal Debt" due and owing
under the Prior Credit Agreement at the Closing Time of no more than the lesser
of (i) Forty Five Million Dollars ($45,000,000) or (ii) the Borrowing Base
(herein defined), all of which constituted "Base Rate Borrowings" under the
Prior Credit Agreement. Immediately after such paydown, Lender will purchase
from Prior Lenders, at par, all of the Prior Obligations, and Lender hereunder
will receive from each Prior Lender an assignment, without recourse,
representation or warranty (the "PRIOR LENDER ASSIGNMENTS"), of (A) the Prior
Obligations, (B) all Liens securing payment and performance of the Prior
Obligations or any part thereof and all guaranties, security agreements,
mortgages, pledges, assignments, deeds of trust and documents and agreements
related thereto and all Rights of Prior Lenders thereunder, (C) the Prior Credit
Agreement and all of Rights of Prior Lenders thereunder and (D) the "Credit
Documents", as defined in the Prior Credit Agreement, and all Rights of Prior
Lenders thereunder.

         D. The Prior Obligations (i) are guaranteed, pursuant to the Prior
Credit Agreement, by unlimited guaranties from Ultrak Operating, L.P. and each
of Parent's other Domestic Subsidiaries (defined herein), (ii) are secured by
Liens (defined herein) on all of the assets of the Domestic Companies (defined
herein) and (iii) are secured by Liens on a certain percentage of the capital
stock of Parent's directly-owned Foreign Subsidiaries (defined herein) and by a

Account.

         "ACCOUNTS" means all present and future rights of Borrower or any

are not evidenced by instruments or chattel paper, and whether or not they have
been earned by performance.

business or division of a Person, (b) the acquisition by any Company of fifty
percent (50%) or more of any class of Voting Stock (or similar ownership
interests) of any Person (provided that, formation or organization of any entity
shall not constitute an "Acquisition" to the extent that the amount of the loan,
advance, investment, or capital contribution in such entity constitutes a
permitted investment under Section 9.7), or (c) a merger, consolidation,
amalgamation, or other combination by any Company with another Person.

         "ADMINISTRATIVE AGENT" means, at any time, American National Bank and
Trust Company of Chicago (or its successor appointed under Section 13), acting

         "AMERICAN NATIONAL" means American National Bank and Trust Company of
Chicago, the initial sole Lender hereunder.

         "APPLICABLE MARGIN" means, for any day, the percentage of interest over
the Base Rate, the LIBOR Rate, or the Eurocurrency Rate, as the case may be,
that is applicable when the Base Rate, the LIBOR Rate, or the Eurocurrency Rate,
as applicable, is determined under this Agreement, which margin of interest
shall be determined in accordance with the provisions as follows:

                  (a) From the Closing Date through the initial EBITDA Rate
         Determination Date, the Applicable Margin shall be two and
         three-fourths percent (2.75%) for LIBOR Rate Borrowings and

                                           AMENDED AND RESTATED CREDIT AGREEMENT

<PAGE>   9





         Eurocurrency Borrowings, and one-fourth of one percent (0.025%) for
         Base Rate Borrowings. The "EBITDA RATE DETERMINATION DATE" is as of the
         last day of each fiscal quarter, beginning September 30, 2000, and any
         rate adjustment will be effective as of the first day of the second
         month (the "EBITDA RATE ADJUSTMENT EFFECTIVE DATE") following the
         applicable EBITDA Rate Determination Date (e.g., if Borrower qualifies
         for a rate adjustment based on the calculation as of September 30,
         2000, the rate adjustment will become effective on November 1, 2000).
         No rate adjustment in Borrower's favor will become effective unless
         Administrative Agent has received the quarterly Financials and
         Compliance Certificate for the applicable EBITDA Rate Determination
         Date, and has therefor received the Financials and Compliance
         Certificates for all prior quarters, in each case, the receipt of which
         occurred within the time periods prescribed by this Agreement.

                  (b) If, as of the end of any month ("DETECTION SYSTEMS RATE
         DETERMINATION DATE"), (i) all of the interest of Parent in Detection
         Systems was sold during such month for cash to a Person who is not an
         Affiliate, and (ii) the Net Proceeds were applied in accordance with
         Section 3.2(c), and (iii) Borrower had at least Ten Million Dollars of
         Excess Availability, without including any amount for the Over-Advance
         Availability in the Borrowing Base, for the entire month ending on the
         Detection Systems Rate Determination Date, and (iv) the Over-Advance
         Availability has been cancelled and terminated at Borrower's written
         request and clause (g) has been eliminated from the definition of
         "Borrowing Base", and (v) no Potential Default or Event of Default has
         occurred and is continuing, then, in such event, the Applicable Margin
         will be reduced by one-fourth of one percent (0.25%) on the first day
         of the month following Detection Systems Rate Determination Date, which
         reduction shall continue in effect until the earlier of (A) the first
         EBITDA Rate Adjustment Effective Date on which Borrower is entitled to
         a reduction pursuant to paragraph (d) of this definition of "Applicable
         Margin" or (B) the last day of a month in which Borrower has less than
         Ten Million Dollars of Excess Availability, without including any
         amount for the Over-Advance Availability in the Borrowing Base.

                  (c) No rate adjustment in favor of Borrower will become
         effective unless, on the applicable EBITDA Rate Adjustment Effective
         Date, (i) the Over-Advance Availability has been cancelled and
         terminated at Borrower's written request and clause (g) has been
         eliminated from the definition of "Borrowing Base", and (ii) no
         Potential Default or Event of Default has occurred and is continuing.

                  (d) After Administrative Agent's timely receipt of the
         Financials and Compliance Certificates referred to in the preceding
         clause (a) with respect to any EBITDA Rate Determination Date, if
         Operating EBITDA is Ten Million Two Hundred Thousand Dollars
         ($10,200,000) or more for the nine months ending September 30, 2000
         with respect to the initial EBITDA Rate Determination Date or Thirteen
         Million Seven Hundred Thousand Dollars ($13,700,000) or more for the
         twelve months ending on any subsequent EBITDA Rate Determination Date,
         the Applicable Margin in effect for the three-month period beginning on
         the applicable EBITDA Rate Adjustment Effective Date shall be adjusted
         based on the average daily Excess Availability, without including any
         amount for the Over-Advance Availability in the Borrowing Base, during
         the quarter ended on the applicable EBITDA Rate Determination Date as
         reflected in the table below. The calculations will be determined from
         such Financials and related Compliance Certificate; provided, however,
         at all times the foregoing shall be subject to the provisions of clause
         (e) of this definition.

         (compliance with the procedures set forth in Section 2.4 and elsewhere
         herein being required for LIBOR Rate Borrowings and Eurocurrency
         Borrowings). Borrower agrees to deliver promptly to Administrative
         Agent a written confirmation, if such confirmation is requested by
         Administrative Agent, of each telephonic notice signed by an Authorized
         Officer. If the written confirmation differs in any material respect
         from the action taken by Administrative Agent, the records of
         Administrative Agent shall govern absent manifest error.


         2.4 Borrowing Procedure. The following procedures apply to all
Borrowings other than Base Rate Borrowings pursuant to Section 2.3:

         (a) Borrowing Request. Borrower may request a Borrowing only by making
or delivering a Borrowing Request to Administrative Agent (or, alternatively, to
the Eurocurrency Lending Installation in the case of Eurocurrency Borrowings),
which is irrevocable and binding on Borrower, stating the Type, amount and
Interest Period for each Borrowing and which must be received by Administrative
Agent (or, alternatively, the Eurocurrency Lending Installation in the case of
Eurocurrency Borrowings) no later than (i) 12:00 noon on the third Business Day
before the date on which funds are requested (the "BORROWING DATE") for any
LIBOR Rate Borrowing, (ii) 10:00 a.m. (London time) on the fourth Business Day
before the Borrowing Date for any Eurocurrency Borrowing, or (iii) 12:00 noon on
the Borrowing Date for any Base Rate Borrowing. If the Borrowing Request for a
Eurocurrency Borrowing delivered pursuant to the immediately-preceding sentence
is sent by facsimile, Borrower shall promptly deliver the originally-executed
Borrowing Request to the Eurocurrency Lending Installation. Administrative Agent
(or, alternatively, the Eurocurrency Lending Installation in the case of
Eurocurrency Borrowings) shall promptly notify each Lender (or any Lending
Installation designated in writing by such Lender to make Eurocurrency
Borrowings on behalf of such Lender) of any Borrowing Request.

         (b) Funding. Each Lender (or its applicable Lending Installation) shall
remit its Commitment Percentage of each requested Borrowing to Administrative
Agent's principal office in Chicago, Illinois (or, alternatively, at the
Eurocurrency Lending Installation in the case of Eurocurrency Borrowings), in
funds that are available for immediate use by Administrative Agent or the
Eurocurrency Lending Installation, as the case may be, by 2:00 p.m. (local time)
on the applicable Borrowing Date. Subject to receipt of those funds,
Administrative Agent or the Eurocurrency Lending Installation, as the case may
be, shall (unless to its actual knowledge any of the applicable conditions
precedent have not been satisfied by Borrower or waived by the requisite Lenders
under Section 14.10) make those funds available to Borrower by (at Borrower's
option) (i) wiring the funds to or for the account of Borrower at the direction
of Borrower or (ii) depositing the funds in one of Borrower's accounts with
Administrative Agent or, in the case of Eurocurrency Borrowings, the
Eurocurrency Lending Installation.

         (c) Funding Assumed. Absent contrary written notice from a Lender,
Administrative Agent or the Eurocurrency Lending Installation, as the case may
be, may assume that each Lender has made its Commitment Percentage of the
requested Borrowing available to Administrative Agent or the Eurocurrency
Lending Installation, as the case may be, on the applicable Borrowing Date, and
Administrative Agent or the Eurocurrency Lending Installation, as the case may
be, may, in reliance upon such assumption (but shall not be required to), make
available to Borrower a corresponding amount. If a Lender fails to make its
Commitment Percentage of any requested Borrowing available to Administrative
Agent or the Eurocurrency

Lending Installation, as the case may be, on the applicable Borrowing Date,
Administrative Agent or the Eurocurrency Lending Installation, as the case may
be, may recover the applicable amount on demand, (i) from that Lender together
with interest, commencing on the Borrowing Date and ending on (but excluding)
the date Administrative Agent or the Eurocurrency Lending Installation, as the
case may be, recovers the amount from that Lender, at an annual interest rate
equal to the Fed Funds Rate (or, alternatively, in the case of Eurocurrency
Borrowings, the Eurocurrency Lending Installation's cost of funds for that
amount and for the period stated above), or (ii) if that Lender fails to pay its
amount upon demand, then from Borrower. No Lender is responsible for the failure
of any other Lender to make its Commitment Percentage of any Borrowing; however,
failure of any Lender to make its Commitment Percentage of any Borrowing does
not excuse any other Lender from making its Commitment Percentage of any
Borrowing.

         2.5      Letters of Credit.

         (a) Conditions. Subject to the terms and conditions of this Agreement
and applicable Laws, Administrative Agent (itself or through one of its
Affiliates, and references in this Section 2.4 to "Administrative Agent" include
those Affiliates) agrees, if requested by Borrower, to issue LCs upon Borrower's
making or delivering an LC Request and delivering an LC Agreement, both of which
must be received by Administrative Agent no later than the fifth Business Day
before the Business Day on which the requested LC is to be issued, so long as
(i) no LC may have an expiration date more than one year from its date of
issuance, (ii) no LC may expire after a date 30 Business Days before the
Revolving Facility Termination Date, (iii) the LC Exposure does not exceed Five
Million Dollars ($5,000,000), (iv) the limitations in Section 2.2 are not
exceeded, and (v) each LC will be denominated in Dollars.

         (b) Participation. Immediately upon Administrative Agent's issuance of
any LC, Administrative Agent shall be deemed to have sold and transferred to
each other Lender, and each other Lender shall be deemed irrevocably and
unconditionally to have purchased and received from Administrative Agent,
without recourse or warranty, an undivided interest and participation to the
extent of such Lender's Commitment Percentage under the Revolving Facility in
the LC and all applicable Rights of Administrative Agent in the LC (other than
Rights to receive certain fees provided in Section 4.4 to be for Administrative
Agent's sole account).

<PAGE>   32



         (c) Reimbursement Obligation. To induce Administrative Agent to issue
and maintain LCs, and to induce Lenders to participate in issued LCs, Borrower
agrees to pay or reimburse Administrative Agent (i) on the date when any draft
or draw request is presented under any LC, the amount paid or to be paid by
Administrative Agent and (ii) promptly, upon demand, the amount of any
additional fees Administrative Agent customarily charges for the application and
issuance of an LC, for amending LC Agreements, for honoring drafts and draw
requests, and for taking similar action in connection with letters of credit. If
Borrower has not reimbursed Administrative Agent for any drafts or draws paid or
to be paid by the date of Administrative Agent's demand for reimbursement,
Administrative Agent is irrevocably authorized to fund Borrower's reimbursement
obligations as a Base Rate Borrowing under the Revolving Facility if proceeds
are available under the Revolving Facility and if the conditions in this
Agreement for such a Borrowing (other than any notice requirements or minimum
funding amounts) have, to Administrative Agent's knowledge, been satisfied. The
proceeds of that Borrowing shall be advanced directly to Administrative Agent to
pay Borrower's unpaid reimbursement obligations. If funds cannot be advanced
under the Revolving Facility, then Borrower's reimbursement obligation shall
constitute a demand obligation. Borrower's obligations under this Section are
part of the Obligation and are absolute and unconditional under any and all
circumstances and irrespective of any setoff, counterclaim, or defense to
payment that Borrower may have at any time against Administrative Agent or any
other Person. From Administrative Agent's demand for reimbursement to the date
paid (including any payment from proceeds of a Base Rate Borrowing), unpaid
reimbursement amounts accrue interest that is payable on demand at the Default
Rate thereafter.

         (d) General. Administrative Agent shall promptly notify Borrower of the
date and amount of any draft or draw request presented for honor under any LC
(but failure to give notice will not affect Borrower's obligations under this
Agreement). Administrative Agent shall pay the requested amount upon presentment
of a draft or draw request unless presentment on its face does not comply with
the terms of the applicable LC. When making payment, Administrative Agent may
disregard (i) any default or potential default that exists under any other
agreement and (ii) obligations under any other agreement that have or have not
been performed by the beneficiary or any other Person (and Administrative Agent
is not liable for any of those obligations). Borrower's reimbursement
obligations to Administrative Agent and Lenders, and each Lender's obligations
to Administrative Agent, under this section are absolute and unconditional
irrespective of, and Administrative Agent is not responsible for, (i) the
validity, enforceability, sufficiency, accuracy, or genuineness of documents or
endorsements (even if they are in any respect invalid, unenforceable,
insufficient, inaccurate, fraudulent, or forged), (ii) any dispute by any
Company with or any Company's claims, setoffs, defenses, counterclaims, or other
Rights against Administrative Agent, any Lender, or any other Person, or (iii)
the occurrence of any Potential Default or Event of Default. However, nothing in
this Agreement constitutes a waiver of Borrower's Rights to assert any claim or
defense based upon the gross negligence or willful misconduct of Administrative
Agent or any Lender. Administrative Agent shall promptly distribute
reimbursement payments received from Borrower to all Lenders according to their
Pro Rata Part of the Revolving Facility.

         (e) Obligation of Lenders. If Borrower fails to reimburse
Administrative Agent as provided in Section 2.4(c) within 24 hours after
Administrative Agent's demand for reimbursement, and funds cannot be advanced
under the Revolving Facility to satisfy the reimbursement obligations,
Administrative Agent shall promptly notify each Lender of Borrower's failure, of
the date and amount paid, and of each Lender's Commitment Percentage of the
unreimbursed amount. Each Lender shall promptly and unconditionally make
available to Administrative Agent in immediately available funds its Commitment
Percentage of the unpaid reimbursement obligation, subject to the limitations of
Section 2.2(d). Funds are due and payable to Administrative Agent before the
close of business on the Business Day when Administrative Agent gives notice to
each Lender of Borrower's reimbursement failure (if notice is given before 1:00
p.m.) or on the next succeeding Business Day (if notice is given after 1:00
p.m.). All amounts payable by any Lender accrue interest


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 26               ULTRAK OPERATING, L.P.

<PAGE>   33



after the due date, and each Lender shall pay to Administrative Agent on demand
interest, at the Fed Funds Rate from the day the applicable draft or draw is
paid by Administrative Agent to (but not including) the date the amount is paid
by the Lender to Administrative Agent.

         (f) Duties of Administrative Agent. Administrative Agent agrees with
each Lender that it will exercise and give the same care and attention to each
LC as it gives to its other letters of credit. Each Lender and Borrower agree
that, in paying any draft or draw under any LC, Administrative Agent has no
responsibility to obtain any document (other than any documents expressly
required by the respective LC) or to ascertain or inquire as to any document's
validity, enforceability, sufficiency, accuracy, or genuineness or the authority
of any Person delivering it. Neither Administrative Agent nor its
Representatives will be liable to any Lender or any Company for any LC's use or
for any beneficiary's acts or omissions. Any action, inaction, error, delay, or
omission taken or suffered by Administrative Agent or any of its Representatives
in connection with any LC, applicable draws, drafts or documents, or the
transmission, dispatch, or delivery of any related message or advice, if in good
faith and in conformity with applicable Laws and in accordance with the
standards of care specified in the Uniform Customs and Practices for Documentary
Credits (1993 Revision), International Chamber of Commerce Publication No. 500
(as amended or modified), is binding upon the Companies and Lenders and does not
place Administrative Agent or any of its Representatives under any resulting
liability to any Company or any Lender. Administrative Agent is not liable to
any Company or any Lender for any action taken or omitted, in the absence of
gross negligence or willful misconduct, by Administrative Agent or its
Representatives in connection with any LC.

         (g) Cash Collateral. On the Revolving Facility Termination Date, and if
requested by Required Lenders while an Event of Default or Potential Default
exists, Borrower shall provide Administrative Agent, for the benefit of Lenders,
cash collateral in an amount to equal the then-existing LC Exposure. After the
expiration of ninety (90) days from the date on which all existing Events of
Default and Potential Defaults have been cured, Administrative Agent will, upon
request of Borrower, release the cash collateral if no Events of Default or
Potential Defaults exist at the time of the release.

         (h) INDEMNIFICATION. BORROWER AND PARENT, JOINTLY AND SEVERALLY, SHALL,
AND HEREBY AGREE TO, PROTECT, INDEMNIFY, PAY, AND SAVE ADMINISTRATIVE AGENT,
EACH LENDER, AND THEIR RESPECTIVE REPRESENTATIVES HARMLESS FROM AND AGAINST ANY
AND ALL CLAIMS, DEMANDS, LIABILITIES, DAMAGES, LOSSES, COSTS, CHARGES, AND
EXPENSES (INCLUDING REASONABLE ATTORNEYS' FEES) WHICH ANY OF THEM MAY INCUR OR
BE SUBJECT TO AS A CONSEQUENCE OF THE ISSUANCE OF ANY LC, ANY DISPUTE ABOUT IT,
OR THE FAILURE OF ADMINISTRATIVE AGENT TO HONOR A DRAFT OR DRAW REQUEST UNDER
ANY LC AS A RESULT OF ANY ACT OR OMISSION (WHETHER RIGHT OR WRONG) OF ANY
PRESENT OR FUTURE GOVERNMENTAL AUTHORITY. HOWEVER, NO PERSON IS ENTITLED TO
INDEMNITY UNDER THE FOREGOING FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT.

         (i) LC Agreements. Although referenced in any LC, terms of any
particular agreement or other obligation to the beneficiary are not incorporated
into this Agreement in any manner. The fees and other amounts payable with
respect to each LC are as provided in this Agreement, drafts and draws under
each LC are part of the Obligation, only the events specified in this Agreement
as an Event of Default shall constitute a default under any LC, and the terms of
this Agreement control any conflict between the terms of this Agreement and any
LC Agreement.

         2.6 Borrowing Requests and LC Requests. Each Borrowing Request and LC
Request constitutes a representation and warranty by Borrower that as of the
Borrowing Date or the date of issuance of the requested LC, as the case may be,
that all of the conditions precedent in SECTION 6 have been satisfied.

         2.7 Termination. Upon giving at least five Business Days prior written
and irrevocable notice to Administrative Agent, Borrower may permanently
terminate all of the unused portion of the Revolving Facility and the Commitment
but may not terminate it in part, except as stated in the next sentence. Upon
the sale of all or a substantial part of the Detection Systems (the Net Proceeds
of which are applied to reduce the Obligation in accordance with Section
3.2(c)(iii)), Borrower may permanently terminate a portion of the Revolving
Facility and reduce the total Commitments to Thirty Five Million Dollars
($35,000,000). Each partial termination must be ratable in accordance with each
Lender's Commitment Percentage. Any partial terminations shall reduce
availability under the Eurocurrency Sublimit on a pro rata basis in the same
proportion which the Eurocurrency Sublimit at the time bears to the total
Commitments. At the time of any termination, Borrower shall pay to
Administrative Agent (or, alternatively, to the Eurocurrency Lending
Installation in the case of Eurocurrency Borrowings), for the account of each
Lender, as applicable, all accrued and unpaid fees under this Agreement, the
interest attributable to the amount of that reduction, and any related Funding
Loss. Any part of the Commitment for the Revolving Facility that is terminated
may not be reinstated.

SECTION 3. TERMS OF PAYMENT.

         3.1 Notes and Payments.

         (a) Notes. The Term Notes and Revolving Notes under the Prior Credit
Agreement acquired by American National from Bank One and Wells Fargo
immediately before the execution of this Agreement will, at the Closing Time, be
renewed and replaced by a single Note hereunder in the face amount of Forty Five
Million Dollars ($45,000,000), executed by Ultrak Operating, L.P., as Borrower,
payable to the order of American National, as Lender, to evidence the Principal
Debt under the Revolving Facility. If American National subsequently sells a
portion of the Obligation to another Entity which assumes a portion of the
Commitment, or if, thereafter, a Lender sells a portion of the Obligation held
by it to another Entity which assumes a portion of the Commitment, then, each
time, Administrative Agent will prepare a new Schedule 2 reflecting the
post-transfer Commitment of each Lender, which will be executed by all Lenders,
and a copy thereof will be sent by Administrative Agent to Borrower and each
Lender. Administrative Agent will cause to be prepared and delivered to Borrower
replacement Notes for each Lender who made a transfer and each Lender who was
the recipient of a transfer, in the face amount of the Commitment of each such
transferee and recipient, and Borrower will promptly execute and deliver such
replacement Notes to Administrative Agent for delivery to the Lenders who are
payees thereof.

         (b) Payment. Except for payment made on Base Rate Borrowings by
appropriate debits to Borrower's Loan Account pursuant to Section 2.3 and
Section 3.4, Borrower must make each payment and prepayment on the Obligation to
Administrative Agent's principal office in Chicago, Illinois (or, alternatively,
at the Eurocurrency Lending Installation in the case of payments and prepayments
made in respect of Eurocurrency Borrowings) in immediately available funds by
1:00 p.m.(local time) on the day due; otherwise, but subject to Section 3.8,
those funds continue to accrue interest as if they were received on the next
Business Day. Administrative Agent or the Eurocurrency Lending Installation, as
applicable, shall promptly pay to each Lender (or a Lending Installation of that
Lender designated in writing to Administrative Agent or the Eurocurrency Lending
Installation, as appropriate) the part of any payment or prepayment to which
that Lender is entitled under this Agreement (in the same type of funds which
the Administrative Agent or the Eurocurrency Lending Installation received) on
the same day Administrative Agent or the Eurocurrency Lending Installation, as
the case may be, receives the funds from Borrower.

         (c) Payment Assumed. Unless Administrative Agent (or, alternatively,
the Eurocurrency Lending Installation in the case of Eurocurrency Borrowings)
has received notice from Borrower prior to the date on


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 28               ULTRAK OPERATING, L.P.

<PAGE>   35



which any payment is due under this Agreement that Borrower will not make that
payment in full, Administrative Agent (or, alternatively, the Eurocurrency
Lending Installation in the case of Eurocurrency Borrowings) may assume that
Borrower has made the full payment due and Administrative Agent (or,
alternatively, the Eurocurrency Lending Installation in the case of Eurocurrency
Borrowings) may, in reliance upon that assumption, cause to be distributed to
each Lender (or a Lending Installation of that Lender designated in writing to
Administrative Agent or the Eurocurrency Lending Installation, as appropriate)
on that date the amount then due to each Lender. If and to the extent Borrower
does not make the full payment due to Administrative Agent (or, alternatively,
the Eurocurrency Lending Installation in the case of Eurocurrency Borrowings),
each Lender shall repay to Administrative Agent (or, alternatively, the
Eurocurrency Lending Installation in the case of Eurocurrency Borrowings) on
demand the amount distributed to that Lender by Administrative Agent (or,
alternatively, the Eurocurrency Lending Installation in the case of Eurocurrency
Borrowings) together with interest for each day from the date that Lender
received payment from Administrative Agent (or, alternatively, the Eurocurrency
Lending Installation in the case of Eurocurrency Borrowings) until the date that
Lender repays Administrative Agent (or, alternatively, the Eurocurrency Lending
Installation in the case of Eurocurrency Borrowings) (unless such repayment is
made on the same day as such distribution), at an interest rate equal to the Fed
Funds Rate (or, alternatively, in the case of Eurocurrency Borrowings, the
Eurocurrency Lending Installation's cost of funds for that amount and for the
period stated above).

         (d) Currency of Payment. All payments and prepayments on the Obligation
must be made in the currency borrowed (the "SPECIFIED CURRENCY") and at the
Lending Installation specified by the Administrative Agent (the "SPECIFIED
PLACE"). The payment of the Obligation shall not be discharged by an amount paid
in another currency or in another place, whether pursuant to a judgment or
otherwise, to the extent that the amount so paid on conversion to the Specified
Currency and transfer to the Specified Place under normal banking procedures
does not yield the amount of the Specified Currency at the Specified Place due
hereunder. If, for the purpose of obtaining judgment in any court, it is
necessary to convert a sum due hereunder in the Specified Currency into another
currency (the "SECOND CURRENCY"), the rate of exchange which shall be applied
shall be that at which in accordance with normal banking procedures the
Administrative Agent could purchase the Specified Currency with the Second
Currency on the Business Day next preceding that on which such judgment is
rendered. The obligation of Borrower in respect of any such sum due from it to
the Administrative Agent or any Lender hereunder (an "ENTITLED PERSON") shall,
notwithstanding the rate of exchange actually applied in rendering such
judgment, be discharged only to the extent that on the Business Day following
receipt by such Entitled Person of any sum adjudged to be due hereunder or under
the other Credit Documents in the Second Currency, such Entitled Person may in
accordance with normal banking procedures purchase and transfer to the Specified
Place the Specified Currency with the amount of the Second Currency so adjudged
to be due; and Borrower hereby, as a separate part of the Obligation and
notwithstanding such judgment, agrees to indemnify such Entitled Person against,
and to pay such Entitled Person on demand, in the Specified Currency, any
difference between the sum originally due to such Entitled Person in the
Specified Currency and the amount of the Specified Currency so purchased and
transferred.

         3.2 Interest and Principal Payments.

         (a) Interest. Accrued interest on each LIBOR Rate Borrowing is due and
payable on the first day of each month, commencing on the first day of the month
following the Closing Date, and on the last day of its respective Interest
Period. Accrued interest on each Base Rate Borrowing is due and payable on the
first day of each month, commencing on the first day of the month following the
Closing Date. Accrued interest on each Eurocurrency Borrowing is due and payable
on the last day of its respective Interest Period (provided that accrued
interest on any Eurocurrency Borrowing having an Interest Period longer than
three months shall also be payable on the last day of each three-month interval
during such Interest Period) and on any date that the Eurocurrency Borrowing is
prepaid, whether by acceleration or otherwise. Accrued interest is also due and
payable (irrespective of the Type of Borrowing) on the Revolving Facility
Termination Date.

         (b) Revolving Facility Principal. The Principal Debt is due and payable
on the Revolving Facility Termination Date. Before that date, Borrower may at
any time prepay, without penalty (except as provided in this Agreement) and in
whole or in part, the Principal Debt, so long as (i) each voluntary partial
prepayment must be in a principal amount not less than Five Hundred Thousand
($500,000) (or its Dollar Equivalent) in the case or prepayments of Eurocurrency
Borrowings or LIBOR Rate Borrowings, (ii) Borrower shall pay any related Funding
Loss upon demand, and (iii) in the case of prepayments of Eurocurrency
Borrowings, Borrower has given the Eurocurrency Lending Installation five days'
advance notice of its intention to make such prepayment. Conversions under
Section 3.14 are not prepayments.

         (c) Mandatory Prepayments.

                  (i) At any time a Borrowing Base Deficiency exists, Borrower
         shall immediately make a prepayment to Administrative Agent or the
         Eurocurrency Lending Installation (with any related Funding Loss) under
         the Revolving Facility so that a Borrowing Base Deficiency no longer
         exists; provided that, notwithstanding the foregoing, Borrower may take
         up to five (5) Business Days to cure a Borrowing Base Deficiency after
         becoming aware of same so long as the amount of the Borrowing Base
         Deficiency does not exceed five percent (5%) of the total Borrowing
         Base.

                  (ii) Immediately upon a sale, lease or other disposition of
         assets by any Company other than a Permitted Asset Sale, Borrower shall
         make a mandatory prepayment to Administrative Agent or the Eurocurrency
         Lending Installation (with any related Funding Loss) under the
         Revolving Facility in an amount equal to one hundred percent (100%) of
         the Net Proceeds of such sale, lease or other disposition.

                  (iii) Immediately upon the sale or other disposition of any of
         Borrower's investment or interest in Detection Systems, Borrower shall
         make a mandatory prepayment on the Obligation to Administrative Agent
         or the Eurocurrency Lending Installation (with any related Funding
         Loss) equal to all of the Net Proceeds of such sale(s) until such time
         as the aggregate of all of such Net Proceeds from Detection Systems
         sales paid hereunder equals Thirteen Million Dollars ($13,000,000).
         With respect to any Net Proceeds in excess of Thirteen Million Dollars
         ($13,000,000), the required mandatory prepayment will be the amount
         included within clause (c) of the Borrowing Base immediately prior to
         the sale or other disposition in question.

                  (iv) If the aggregate principal amount of Eurocurrency
         Borrowings outstanding (after converting each Eurocurrency to its
         Dollar Equivalent) at any time exceeds the Eurocurrency Sublimit, then,
         upon five Business Days' written notice from the Eurocurrency Lending
         Installation, Administrative Agent or any Lender, Borrower shall prepay
         an aggregate principal amount of


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 30               ULTRAK OPERATING, L.P.

<PAGE>   37



         Eurocurrency Borrowings sufficient to bring the aggregate of the
         Eurocurrency Borrowings outstanding within the Eurocurrency Sublimit.

         3.3 Interest Options. Except that the LIBOR Rate and the Eurocurrency
Rate may not be selected when an Event of Default or Potential Default exists,
and except as otherwise provided in this Agreement, Borrowings bear interest at
an annual rate equal to the lesser of (a) the Base Rate plus the Applicable
Margin and (b) the Maximum Rate, unless Borrower has elected to make a LIBOR
Rate Borrowing or a Eurocurrency Borrowing or has elected to convert a portion
of the Base Rate Borrowings to a LIBOR Rate Borrowing or a Eurocurrency
Borrowing. LIBOR Rate Borrowings will bear interest at an annual rate equal to
the lesser of (i) the LIBOR Rate plus the Applicable Margin and (ii) the Maximum
Rate. Eurocurrency Borrowings will bear interest at an annual rate equal to the
lesser of (A) the Eurocurrency Rate plus the Applicable Margin and (B) the
Maximum Rate. Each change in the Base Rate, LIBOR Rate, Eurocurrency Rate, or
Maximum Rate is effective, without notice to Borrower or any other Person, upon
the effective date of change.

         3.4 Collection of Accounts and Payments. Borrower shall establish lock
box accounts ("LOCK BOX ACCOUNTS") and blocked accounts (the "BLOCKED ACCOUNTS")
with Administrative Agent and with such banks as are acceptable to
Administrative Agent (collectively, the "COLLECTING BANKS") to which all Account
Debtors shall directly remit all payments on Accounts and in which Borrower and
each other Company will immediately deposit all cash and other payments made for
Inventory and other payments constituting proceeds of Collateral in the
identical form in which such payment was made, whether by cash or check. The
Collecting Banks shall acknowledge and agree, in a manner satisfactory to
Administrative Agent, that all payments made to the Blocked Accounts are the
sole and exclusive property of Administrative Agent, for the benefit of Lenders,
that the Collecting Banks have no right to setoff against the Blocked Accounts
and that the Collecting Banks will wire or otherwise transfer immediately
available funds in a manner satisfactory to Administrative Agent, funds
deposited into the Blocked Accounts to Administrative Agent on a daily basis as
soon as such funds are collected. Borrower hereby agrees that all payments made
to the Lock Box Accounts, Blocked Accounts or otherwise received by the
Collecting Banks or Administrative Agent or any Lender, whether on the Accounts
or as proceeds of Borrower's other Collateral or otherwise will be the sole and
exclusive property of Administrative Agent, for the ratable benefit of Lenders,
and will be applied on account of Borrower's Liabilities as follows: (i) when
the funds have become available, for collection of checks and other instruments
(including automatic clearing house electronic funds transfers and depository
transfer checks) received by Administrative Agent at its offices in Chicago,
Illinois, Administrative Agent will credit (conditional upon final collection)
all such payments to Borrower's Loan Account and (ii) all cash payments received
by Administrative Agent at its offices in Chicago, Illinois, including, without
limitation, payments made by wire transfer of immediately available funds
received by Administrative Agent in time for posting to the account of
Administrative Agent, for the ratable benefit of Lenders (and, in any event, not
later than 4:00 p.m. Chicago time) on the date received, will be credited to
Borrower's Loan Account immediately upon receipt. Borrower and each of its
Affiliates, Subsidiaries, members, managers, officers, employees, agents or
those Persons acting for or in concert with Borrower shall, acting as trustee
for Administrative Agent, receive, as the sole and exclusive property of
Administrative Agent, any monies, checks, notes, drafts or any other payment
relating to and/or proceeds of Borrower's Accounts or other Collateral which
come into the possession or under the control of Borrower or any of its
Affiliates, Subsidiaries, shareholders, members, managers, employees, agents or
those Persons acting for or in concert with Borrower and immediately upon
receipt thereof, Borrower shall remit the same or cause the same to be remitted,
in kind, to Administrative Agent, at Administrative Agent's address set forth
below. Borrower agrees to pay to Administrative Agent any and all fees, costs
and expenses which Administrative Agent incurs in connection with opening and
maintaining Borrower's Lock Box Accounts and Blocked Accounts and depositing for
collection by Administrative Agent any check or item of payment received and/or
delivered to any Collecting Bank or Administrative Agent, respectively, on
account of the Liabilities and Borrower further


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 31               ULTRAK OPERATING, L.P.

agrees to reimburse Administrative Agent and Lenders for any claims asserted by
the Collecting Banks in connection with Borrower's Blocked Accounts and any
amounts paid to any Collecting Bank arising out of Administrative Agent's or
Lenders' indemnification of such Collecting Bank against damages incurred by the
Collecting Bank in the operation of any Blocked Account.

         3.5 Appointment of Administrative Agent as Borrower's Attorney-in-Fact.
Borrower hereby irrevocably designates, makes, constitutes and appoints
Administrative Agent (and all officers, employees, agents and other Persons
designated by Administrative Agent) as Borrower's true and lawful
attorney-in-fact, and authorizes Administrative Agent, in Borrower's or
Administrative Agent's name, to: (a) following the occurrence and during the
continuance of a Default (i) demand payment of Accounts; (ii) enforce payment of
Accounts by legal proceedings or otherwise; (iii) exercise all of Borrower's
rights and remedies with respect to proceedings brought to collect an Account;
(iv) sell or assign any Account upon such terms, for such amount and at such
time or times as Administrative Agent deems advisable; (v) settle, adjust,
compromise, extend or renew any Account; (vi) discharge and release any Account;
(vii) prepare, file and sign Borrower's name on any proof of claim in bankruptcy
or other similar document against an Account Debtor; (viii) notify the post
office authorities to change the address for delivery of Borrower's mail to an
address designated by Administrative Agent, and open and deal with all mail
addressed to Borrower; and (ix) do all acts and things which are necessary, in
Administrative Agent's sole discretion, to fulfill Borrower's obligations under
this Agreement; and (b) at any time (i) take control in any manner of any item
of payment or proceeds thereof; (ii) have access to any lockbox or postal box
into which Borrower's mail is deposited; (iii) endorse Borrower's name upon any
items of payment or proceeds thereof and deposit the same in Administrative
Agent's account on account of the Liabilities; (iv) endorse Borrower's name upon
any chattel paper, document, instrument, invoice, or similar document or
agreement relating to any Account or any goods pertaining thereto; and (v) sign
Borrower's name on any verification of Accounts and notices thereof to Account
Debtors.

         3.6 Instruments and Chattel Paper. Immediately upon Borrower's receipt
thereof, Borrower shall deliver or cause to be delivered to Administrative
Agent, with appropriate endorsement and assignment to vest title and possession
in Administrative Agent, with full recourse to Borrower, all chattel paper and
instruments which Borrower now owns or may at any time or times hereafter
acquire in order to permit Administrative Agent to perfect its security interest
in such property.

         3.7 Notice to Account Debtors. Administrative Agent may, in its sole
discretion, exercised in a commercially reasonable manner, at any time or times
and without prior notice to Borrower if an Event of Default has occurred and is
continuing (or five (5) days prior written notice to Borrower if no Event of
Default has occurred and is continuing), notify any or all Account Debtors that
the Accounts have been assigned to Administrative Agent and that Administrative
Agent has a security interest therein. Administrative Agent may direct any or
all Account Debtors to make all payments upon the Accounts directly to
Administrative Agent. Administrative Agent shall furnish Borrower with a copy of
any such notice.

         3.8 Quotation of Rates. Borrower may call Administrative Agent or the
Eurocurrency Lending Installation before delivering a Borrowing Request to
receive an indication of the interest rates then in effect, but the indicated
rates do not bind Administrative Agent, the Eurocurrency Lending Installation or
Lenders or affect the interest rate that is actually in effect when Borrower
makes a Borrowing Request, on the date any rate of interest is determined under
this Agreement, or on the applicable Borrowing Date.

         3.9 Default Rate. All past-due Principal Debt and, unless prohibited by
applicable Government Requirements, past-due interest accruing on the Principal
Debt shall, at Administrative Agent's option, bear interest on the amount
thereof from time to time outstanding from the date due (stated or by
acceleration) at the Default Rate until paid, regardless whether payment is made
before or after entry of a judgment.

<PAGE>   39



         3.10 Interest Recapture. If the designated interest rate applicable to
any Borrowing exceeds the Maximum Rate, the interest rate on that Borrowing is
limited to the Maximum Rate, but any subsequent reductions in the designated
rate shall not reduce the interest rate thereon below the Maximum Rate until the
total amount of accrued interest equals the amount of interest that would have
accrued if that designated rate had always been in effect. If at maturity
(stated or by acceleration), or at final payment of the Obligation, the total
interest paid or accrued is less than the interest that would have accrued if
the designated rates had always been in effect, then, at that time and to the
extent not prohibited by applicable Laws, Borrower shall pay an amount equal to
the difference between (a) the lesser of the amount of interest that would have
accrued if the designated rates had always been in effect and the amount of
interest that would have accrued if the Maximum Rate had always been in effect,
and (b) the amount of interest actually paid or accrued on the Obligation.

         3.11 Interest Calculations. Interest on all Borrowings will be
calculated on the basis of actual number of days (including the first day but
excluding the last day) elapsed but computed as if each calendar year consisted
of (a) 360 days in the case of all Borrowings other than Eurocurrency Borrowings
denominated in pounds sterling (unless such calculation would result in the
interest on the Borrowings exceeding the Maximum Rate in which event such
interest shall be calculated on the basis of a year of 365 or 366 days, as the
case may be), and (b) 365 days in the case of Eurocurrency Borrowings
denominated in pounds sterling. All interest rate determinations and
calculations by Administrative Agent are conclusive and binding absent manifest
error.

         3.12 Maximum Rate. It is the intent of Administrative Agent, Lenders
and Borrower in the execution and performance of the Credit Documents to remain
in strict compliance with applicable Laws from time to time in effect, including
applicable laws limiting the amount or rate of interest. Administrative Agent,
Lenders and Borrower stipulate and agree that none of the terms and provisions
contained in the Credit Documents shall ever be construed to create a contract
to pay for the use, forbearance or detention of money with interest at a rate or
in an amount in excess of the Maximum Rate or Maximum Amount. For purposes of
the Credit Documents, "interest" shall include the aggregate of all charges
which constitute interest under applicable Laws that are contracted for,
charged, reserved, received or paid under the Credit Documents. Borrower shall
never be required to pay unearned interest and shall never be required to pay
interest at a rate or in an amount in excess of the Maximum Rate or Maximum
Amount, and the provisions of this section shall control over all other
provisions of the Credit Documents, and of any other instrument pertaining to or
securing the Obligation, which may be in actual or apparent conflict herewith.
If the Obligation is prepaid, or if the maturity of the Obligation is
accelerated for any reason, or if under any contingency the effective rate or
amount of interest which would otherwise be payable under the Credit Documents
would exceed the Maximum Rate or Maximum Amount, or in the event any Lender or
any holder of the Obligation shall charge, contract for, take, reserve or
receive monies that are deemed to constitute interest which would, in the
absence of this provision, increase the effective rate or amount of interest
payable under the Credit Documents to a rate or amount in excess of that
permitted to be charged, contracted for, taken, reserved or received under
applicable Laws then in effect, then the principal amount of the Obligation or
the amount of interest which would otherwise be payable on the Obligation or
both shall be reduced to the amount allowed under applicable Laws as now or
hereinafter construed by the courts having jurisdiction, and all such moneys so
charged, contracted for, taken, reserved or received that are deemed to
constitute interest in excess of the Maximum Rate shall immediately be returned
to or credited to the account of Borrower upon such determination.
Administrative Agent, Lenders and Borrower further stipulate and agree that,
without limitation of the foregoing, all calculations of the rate or amount of
interest contracted for, charged, taken, reserved or received under the Credit
Documents which are made for the purpose of determining whether such rate or
amount exceeds the Maximum Rate or Maximum Amount, shall be made to the extent
not prohibited by applicable Laws, by amortizing, prorating, allocating and
spreading during the period of the full stated term of the Obligation, all
interest at any time contracted for, charged, taken, reserved or received from
Borrower or


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 33               ULTRAK OPERATING, L.P.

<PAGE>   40



otherwise by Lenders or any other holder of the Notes. If the Laws of the State
of Texas are applicable for purposes of determining the "Maximum Rate", such
term shall mean "the "weekly rate ceiling" from time to time in effect under
Chapter 1D., Subtitle 1, Title 79, Revised Civil Statutes of Texas (Article
5069-1D.001 et seq.), as amended, or, if permitted by applicable Law and
effective upon the giving of the notices required by such applicable Law (or
effective upon any other date otherwise specified by applicable Law), the
"monthly ceiling," the "quarterly ceiling," or "annualized ceiling" from time to
time in effect under such applicable Law whichever that the Lenders shall elect
to substitute for the "weekly rate ceiling,"

         3.13 Interest Periods. When Borrower requests any LIBOR Rate Borrowing
or any Eurocurrency Borrowing, Borrower may elect the applicable interest period
(each an "INTEREST PERIOD"), which may be, at Borrower's option, one, three or
six months, subject to the following conditions: (i) the initial Interest Period
for a LIBOR Rate Borrowing or a Eurocurrency Borrowing commences on the
applicable Borrowing Date or conversion date, and each subsequent Interest
Period applicable to any Borrowing commences on the day when the next preceding
applicable Interest Period expires; (ii) if any Interest Period for a LIBOR Rate
Borrowing or a Eurocurrency Borrowing begins on a day for which no numerically
corresponding Business Day in the calendar month at the end of the Interest
Period exists, then the Interest Period ends on the last Business Day of that
calendar month; (iii) if Borrower is required to pay any portion of a LIBOR Rate
Borrowing or a Eurocurrency Borrowing before the end of its Interest Period in
order to comply with the payment provisions of the Credit Documents, Borrower
shall also pay any related Funding Loss and accrued interest on the prepaid
amount; (iv) no Interest Period for any portion of Principal Debt may extend
beyond the scheduled repayment date for that portion of Principal Debt; and (v)
no more than six Interest Periods may be in effect at one time.

         3.14 Conversions.

         (a) Domestic Borrowings. Subject to the dollar limits of Section 2.2(b)
and provided that Borrower may not convert to or select a new Interest Period
for a LIBOR Rate Borrowing at any time when an Event of Default exists, Borrower
may (i) convert a LIBOR Rate Borrowing on the last day of the applicable
Interest Period to a Base Rate Borrowing, (ii) convert a Base Rate Borrowing at
any time to a LIBOR Rate Borrowing, and (iii) elect a new Interest Period for a
LIBOR Rate Borrowing. That election may be made by delivering a Conversion
Notice to Administrative Agent no later than 12:00 noon on the Business Day
before the conversion date or the last day of the Interest Period, as the case
may be (for conversion to a LIBOR Rate Borrowing or election of a new Interest
Period), and no later than 12:00 noon on the last day of the Interest Period
(for conversion to a Base Rate Borrowing). If the Conversion Notice for a
Eurocurrency Borrowing delivered pursuant to the immediately-preceding sentence
is delivered by facsimile, Borrower shall promptly deliver the
originally-executed Conversion Notice to the Administrative Agent. Absent
Borrower's request for conversion or election of a new Interest Period or if an
Event of Default exists, then, a LIBOR Rate Borrowing shall be deemed converted
to a Base Rate Borrowing effective when the applicable Interest Period expires.
For the avoidance of doubt, no portion of any Domestic Borrowing may be
converted to a Eurocurrency Borrowing (but, subject to compliance with the other
terms and conditions of this Agreement, a Eurocurrency Borrowing may be made to
pay all or any portion of any Domestic Borrowing).

         (b) Eurocurrency Borrowings. Subject to the dollar limits of Section
2.2(b) and provided that Borrower may not convert to or select a new Interest
Period for a Eurocurrency Borrowing at any time when an Event of Default exists,
Borrower may elect a new Interest Period for a Eurocurrency Borrowing. That
election may be made by delivering a Conversion Notice to the Eurocurrency
Lending Installation no later than 10:00 a.m. (London time) on the fourth
Business Day before the last day of the Interest Period. If the Conversion
Notice delivered pursuant to the immediately-preceding sentence is delivered by
facsimile, Borrower shall promptly deliver the originally-executed Conversion
Notice to the Eurocurrency Lending Installation. Absent

AMERICAN NATIONAL BANK              Page 34               ULTRAK OPERATING, L.P.

<PAGE>   41



Borrower's request for election of a new Interest Period or if an Event of
Default exists, then a Eurocurrency Borrowing shall be continued for successive
one-month Interest Periods (at the option of Administrative Agent), each
beginning on the date following the last day of the immediately-preceding
Interest Period. For the avoidance of doubt, no portion of any Eurocurrency
Borrowing may be converted to a Base Rate Borrowing or a LIBOR Rate Borrowing
(but, subject to compliance with the other terms and conditions of this
Agreement, a Domestic Borrowing may be made to pay any Eurocurrency Borrowing).

         3.15 Order of Application. Any payment or prepayment shall be applied
to the Obligation in such order and manner as Administrative Agent, in its sole
discretion, may elect. Each payment or prepayment shall be distributed to each
Lender in accordance with its Pro Rata Part of that payment or prepayment.

         3.16 Sharing of Payments, Etc. If any Lender obtains any payment or
prepayment with respect to the Obligation (whether voluntary, involuntary, or
otherwise, including as a result of exercising its Rights under Section 3.17)
that exceeds the part of that payment or prepayment that it is then entitled to
receive under the Credit Documents, then that Lender shall purchase from the
other Lenders participations that will cause the purchasing Lender to share the
excess payment or prepayment ratably with each other Lender. If all or any
portion of any excess payment or prepayment is subsequently recovered from the
purchasing Lender, then the purchase shall be rescinded and the purchase price
restored to the extent of the recovery. Borrower agrees that any Lender
purchasing a participation from another Lender under this section may, to the
fullest extent permitted by applicable Laws, exercise all of its Rights of
payment (including the Right of offset) with respect to that participation as
fully as if that Lender were the direct creditor of Borrower in the amount of
that participation.

         3.17 Offset. If an Event of Default exists, to the extent not
prohibited by applicable Laws, each Lender may exercise (for the benefit of all
Lenders in accordance with Section 3.16) the Rights of offset and banker's Lien
against each and every account and other property, or any interest therein, that
any Company may now or hereafter have with, or which is now or hereafter in the
possession of, that Lender to the extent of the full amount of the Obligation
owed (directly or participated) to it.

         3.18 Booking Borrowings. To the extent permitted by applicable Laws,
any Lender may make, carry, or transfer its Borrowings at, to, or for the
account of any of its Lending Installations, and may change such Lending
Installations from time to time. All terms of this Agreement shall apply to any
such Lending Installation and the Notes shall be deemed held by each Lender for
the benefit of such Lending Installation. Each Lender may, by written notice to
the Administrative Agent and Borrower, designate a Lending Installation through
which Borrowings are made and for whose account loan payments and prepayments
are to be made. Unless otherwise notified to the contrary, all Eurocurrency
Borrowings shall be made by the Lending Installations of each Lender designated
on Schedule 2.

         3.19 Basis Unavailable or Inadequate for LIBOR Rate or Eurocurrency
Rate. If on or before any date when a LIBOR Rate or a Eurocurrency Rate is to be
determined for a Borrowing, Administrative Agent or any Lender determines (and
Required Lenders agree with that determination) that the basis for determining
the applicable rate is not available or that the resulting rate does not
accurately reflect the cost to Lenders of making or converting Borrowings at
that rate for the applicable Interest Period, then Administrative Agent shall
promptly notify Borrower and Lenders of that determination (which is conclusive
and binding on Borrower absent manifest error), and the applicable Borrowing
shall bear interest (i) in the case of Domestic Borrowings, at the sum of the
Base Rate plus the Applicable Margin, and (ii) in the case of Borrowings under
the Eurocurrency Sublimit, at a rate of interest for such period as is
agreed-upon by Administrative Agent, Lenders and Borrower prior to the making of
such Borrowing. Until Administrative Agent notifies Borrower that those
circumstances giving rise to such notice no longer exist, Lenders' commitments
under this Agreement to make, or to convert to, LIBOR Rate Borrowings or
Eurocurrency Borrowings, as the case may be, shall be suspended.


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 35               ULTRAK OPERATING, L.P.

<PAGE>   42



         3.20 Additional Costs. Each Lender severally and not jointly agrees to
notify Administrative Agent, the other Lenders, and Borrower within 180 days
after it has actual knowledge that any circumstances exist that would give rise
to any payment obligation by Borrower under clauses (a) through (c) below.
Although no Lender shall have any liability to Administrative Agent, any other
Lender, or any Company for its failure to give that notice, Borrower is not
obligated to pay any amounts under those clauses that arise, accrue or are
imposed more than 180 days before that notice to the extent it is applicable to
those amounts. To demand payment under this section, any such Lender must
generally be making similar demand for similar additional costs under credit
agreements to which it is party that contain similar provisions to this section.

         (a) Reserves. With respect to any LIBOR Rate Borrowing or Eurocurrency
Borrowing (i) if any change in any present Law, any change in the interpretation
or application of any present Law, or any future Law imposes, modifies or deems
applicable (or if compliance by any Lender or any applicable Lending
Installation with any requirement of any Governmental Authority results in) any
requirement that any reserves (including any marginal, emergency, supplemental,
or special reserves) be maintained (other than any reserve included in the
Reserve Requirement) and if (ii) those reserves reduce any sums receivable by
that Lender or any applicable Lending Installation under this Agreement or
increase the costs incurred by Lender or any applicable Lending Installation in
advancing or maintaining any portion of any LIBOR Rate Borrowing or Eurocurrency
Borrowing, then (iii) that Lender (through Administrative Agent) shall deliver
to Borrower a certificate setting forth in reasonable detail the calculation of
the amount necessary to compensate it or the applicable Lending Installation for
its reduction or increase (which certificate is conclusive and binding absent
manifest error), and (iv) Borrower shall pay that amount to that Lender or
applicable Lending Installation within ten Business Days after demand. The
provisions of and undertakings and indemnifications in this clause (a) survive
the satisfaction and payment of the Obligation and termination of this
Agreement.

         (b) Capital Adequacy. With respect to any Borrowing or LC, if any
change in any present Law, any change in the interpretation or application of
any present Law, or any future Law regarding capital adequacy, or if compliance
by Administrative Agent (as issuer of LCs) or any Lender with any request,
directive or requirement imposed in the future by any Governmental Authority
regarding capital adequacy, or if any change in its written policies or in the
risk category of this transaction, in any of the foregoing events or
circumstances, reduces the rate of return on its capital as a consequence of its
obligations under this Agreement to a level below that which it otherwise could
have achieved (taking into consideration its policies with respect to capital
adequacy) by an amount deemed by it to be material (and it may, in determining
the amount, utilize reasonable assumptions and allocations of costs and expenses
and use any reasonable averaging or attribution method), then (unless the effect
is already reflected in the rate of interest then applicable under this
Agreement) Administrative Agent or that Lender (through Administrative Agent)
shall notify Borrower and deliver to Borrower a certificate setting forth in
reasonable detail the calculation of the amount necessary to compensate it
(which certificate is conclusive and binding absent manifest error), and
Borrower shall pay that amount to Administrative Agent or that Lender within ten
Business Days after demand. The provisions of and undertakings and
indemnification in this clause (b) shall survive the satisfaction and payment of
the Obligation and termination of this Agreement.

         (c) Taxes. Any Taxes payable by Administrative Agent, any Lender, or
any applicable Lending Installation, or ruled by a Governmental Authority to be
payable by Administrative Agent, any Lender, or any applicable Lending
Installation in respect of this Agreement or any other Credit Document shall, if
permitted by applicable Laws, be paid by Borrower, together with interest and
penalties, if any, except for Taxes payable on or measured by the overall net
income of Administrative Agent or that Lender (or any other Person with whom
Administrative Agent or that Lender files a consolidated, combined, unitary, or
similar Tax return) and


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 36               ULTRAK OPERATING, L.P.

<PAGE>   43



except for interest and penalties incurred as a result of the gross negligence
or willful misconduct of Administrative Agent or that Lender. Administrative
Agent or that Lender (through Administrative Agent) shall notify Borrower and
deliver to Borrower a certificate setting forth in reasonable detail the
calculation of the amount of Taxes payable, which certificate is conclusive and
binding (absent manifest error), and Borrower shall pay that amount to
Administrative Agent for its account or the account of that Lender or the
applicable Lending Installation, as the case may be, within ten Business Days
after demand. If Administrative Agent, that Lender or the applicable Lending
Installation subsequently receives a refund of the Taxes paid to it by Borrower,
then the recipient shall promptly pay the refund to Borrower.

         3.21 Change in Laws.

         (a) Domestic Borrowings. If any Law makes it unlawful for any Lender to
make or maintain LIBOR Rate Borrowings, then that Lender shall promptly notify
Borrower and Administrative Agent, and (i) as to undisbursed funds, that
requested Borrowing shall be made as a Base Rate Borrowing and (ii) as to any
outstanding Borrowing (a) if maintaining the Borrowing until the last day of the
applicable Interest Period is unlawful, the Borrowing shall be converted to a
Base Rate Borrowing as of the date of notice, in which event Borrower will not
be required to pay any related Funding Loss or (b) if not prohibited by
applicable Laws, the Borrowing shall be converted to a Base Rate Borrowing as of
the last day of the applicable Interest Period or (c) if any conversion will not
resolve the unlawfulness, Borrower shall promptly prepay the Borrowing, without
penalty but with related Funding Loss.

         (b) Eurocurrency Borrowings. If any Law makes it unlawful for any
Lender to make or maintain Eurocurrency Borrowings, then that Lender shall
promptly notify Borrower and Administrative Agent, and (i) as to undisbursed
funds, that requested Borrowing shall be made at a rate of interest for the
applicable Interest Period as is agreed-upon by Administrative Agent, Lenders
and Borrower prior to the making of such Borrowing, and (ii) as to any
outstanding Borrowing (a) if maintaining the Borrowing until the last day of the
applicable Interest Period is unlawful, the Borrowing shall be converted to a
Borrowing at a rate of interest for the applicable Interest Period as is
agreed-upon by Administrative Agent, Lenders and Borrower or (b) if
Administrative Agent, Lenders and Borrower are unable to agree on a new rate of
interest for that Borrowing, Borrower shall promptly prepay the Borrowing,
without penalty but with related Funding Loss.

         3.22 Funding Loss. BORROWER AND PARENT, JOINTLY AND SEVERALLY, SHALL,
AND HEREBY AGREE TO, INDEMNIFY EACH LENDER AGAINST, AND PAY TO IT UPON DEMAND,
ANY FUNDING LOSS OF THAT LENDER. WHEN ANY LENDER DEMANDS THAT BORROWER PAY ANY
FUNDING LOSS, THAT LENDER SHALL DELIVER TO BORROWER AND ADMINISTRATIVE AGENT A
CERTIFICATE SETTING FORTH IN REASONABLE DETAIL THE BASIS FOR IMPOSING THE
FUNDING LOSS AND THE CALCULATION OF THE AMOUNT, WHICH CALCULATION IS CONCLUSIVE
AND BINDING ABSENT MANIFEST ERROR. THE PROVISIONS OF AND UNDERTAKINGS AND
INDEMNIFICATION IN THIS SECTION SURVIVE THE SATISFACTION AND PAYMENT OF THE
OBLIGATION AND TERMINATION OF THIS AGREEMENT.

         3.23 Foreign Lenders, Participants, and Assignees. Each Lender,
Participant (by accepting a participation interest under this Agreement), and
Assignee (by executing a Note and Lien Assignment) that is not organized under
the Laws of the United States or one of its states (a) represents to
Administrative Agent and Borrower that (i) no Taxes are required to be withheld
by Administrative Agent or Borrower with respect to any payments to be made to
it in respect of the Obligation and (ii) it has furnished to Administrative
Agent and Borrower two duly completed copies of either U.S. Internal Revenue
Service Form 4224, Form 1001, Form W-8, or any other form acceptable to
Administrative Agent and Borrower that entitles it to a complete exemption from
U.S. federal withholding Tax on all interest or fee payments under the Credit
Documents, and (b) covenants to


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 37               ULTRAK OPERATING, L.P.

<PAGE>   44


(i) provide Administrative Agent and Borrower a new Form 4224, Form 1001, Form
W-8, or other form acceptable to Administrative Agent and Borrower upon the
expiration or obsolescence according to applicable Laws of any previously
delivered form, duly executed and completed by it, entitling it to a complete
exemption from U.S. federal withholding Tax on all interest and fee payments
under the Credit Documents, and (ii) comply from time to time with all
applicable Laws with regard to the withholding Tax exemption. If any of the
foregoing is not true at any time or the applicable forms are not provided, then
Borrower and Administrative Agent (without duplication) may deduct and withhold
from interest and fee payments under the Credit Documents any Tax at the maximum
rate under the IRC or other applicable Law, and amounts so deducted and withheld
shall be treated as paid to that Lender, Participant, or assignee, as the case
may be, for all purposes under the Credit Documents.

SECTION 4. FEES.

         4.1 Treatment of Fees. The fees described in this Section 4 (i) are not
compensation for the use, detention or forbearance of money, (ii) are in
addition to, and not in lieu of, interest and expenses otherwise described in
the Credit Documents, (iii) are payable in accordance with Section 3.1, (iv) are
non-refundable, (v) to the fullest extent not prohibited by applicable Laws,
bear interest, if not paid when due, on the amount thereof from time to time
unpaid at the Default Rate and (vi) with respect to the fees referenced in
Sections 4.3 and 4.4, are calculated on the basis of the actual number of days
(including the first day but excluding the last day) elapsed, as if each
calendar year consisted of 360 days, unless such amount is determined to
constitute interest and if so, such computation would result in an interest rate
deemed to exceed (notwithstanding the foregoing) the Maximum Rate in which event
the computation is made on the basis of a year of 365 or 366 days, as the case
may be.

         4.2 Arrangement and Underwriting Fees. Borrower shall pay to
Administrative Agent arrangement, structure, management, documentation, due
diligence and custodial fees in amounts and upon such payment terms as may be
separately agreed upon by Borrower and Administrative Agent in writing.

         4.3 Unused Facility Fee. Borrower shall pay to Administrative Agent for
the account of each Lender, according to each Lender's Commitment Percentage on
the day the fee is payable, an unused facility fee for the Revolving Facility.
The fee accrues on the last day of each month (the "ACCRUAL MONTH"), commencing
March 31, 2000 and is due and payable in arrears on the first day of the month
following the Accrual Month and on the Revolving Facility Termination Date. The
fee is equal to the product of (i) three-eighths of one percent (0.375%) times
(ii) the amount by which the average-daily total Commitment exceeds the sum of
the average-daily Principal Debt (including the Dollar Equivalent of any
Eurocurrency Borrowings) plus the average-daily LC Exposure, times (iii) a
fraction with the number of days in the applicable Accrual Month or portion of
it as the numerator and 360 as the denominator.

                  (a) For the account of each Lender, according to each Lender's
         Commitment Percentage on the day the fee is payable, an issuance fee,
         payable monthly in arrears, equal to two percent (2%) per annum of the
         average, undrawn face amount of that LC during each applicable month;
         and

                  (b) For the account of Administrative Agent, payable on the
         date of issuance, a fronting fee of the greater of (A) Three Hundred
         Dollars ($300) or (B) one eighth of one percent (0.125%) of the face
         amount of each standby LC.

         4.5 Agency Fee. Borrower shall pay an agency fee to Administrative
Agent equal to One Hundred Thousand Dollars ($100,000) for the initial two years
of the Revolving Facility, payable in advance in equal quarterly installments of
Twelve Thousand Five Hundred Dollars ($12,500) each on the Closing Date and on
each July 1, October 1, January 1 and April 1 thereafter. Any unpaid portion of
the $100,000 agency fee shall be due and payable in full if the Obligation is
prepaid in full (other than from the proceeds of a refinancing provided by an
Affiliate of Administrative Agent). Although Administrative Agent and Lenders
have no obligation to extend the Revolving Facility beyond the Revolving
Facility Termination Date, if the Revolving Facility is extended by mutual
agreement of the parties, the agency fee will be $50,000 per year, or portion
thereof, payable in quarterly installments of Twelve Thousand Five Hundred
Dollars ($12,500) in advance.

         4.6 Prepayment Fee. If the Obligation is entirely prepaid (at one time
or as part of a series of related transactions) at any time prior to March 31,
2002, Borrower shall pay to Administrative Agent for the account of each Lender,
according to each Lender's Commitment Percentage on the day the fee is payable,
a prepayment fee equal to one percent (1.0%) of the total Commitments of all
Lenders as of the Closing Date, unless the prepayment is the direct and
immediate result of the sale of all of the Companies to a third party who is not
an Affiliate of any of the Companies, in which case the prepayment fee will be
one half of one percent (0.50%) of the total Commitments of all Lenders as of
the Closing Date; provided that if the prepayment represents the proceeds of a
refinancing provided after December 31, 2000 by an Affiliate of Administrative
Agent, no prepayment fee will be payable.

SECTION 5. SECURITY.

         5.1 Guaranties. Borrower and Parent shall, and shall cause each present
Subsidiary to, (a) unconditionally reaffirm their existing Guaranties of the
full payment and performance of the Obligation by due execution and delivery on
the Closing Date of an Amended and Restated Guaranty substantially in the form
of Exhibit B (other than any Foreign Subsidiary the execution of a Guaranty by
which would create a material Tax obligation for the Companies that would not
otherwise exist) and (b) unconditionally reaffirm the existing Credit Documents
granting Liens in all Collateral now or hereafter owned by any of the Domestic
Companies, by due execution and delivery on the Closing Date of an Amended and
Restated Security Agreement to Administrative Agent for the benefit of Lenders
substantially in the form of Exhibit C. Parent shall on the Closing Date, and
Parent and Borrower shall cause each future Subsidiary at the time of
organization to, (a) execute and deliver a Guaranty unconditionally guaranteeing
the full payment and performance of the Obligation (other than any Foreign
Subsidiary the execution of a Guaranty by which would create a material Tax
obligation for the Companies that would not otherwise exist) and (b) execute and
deliver a Security Agreement granting Liens in all Collateral now or hereafter
owned by Parent and each future Subsidiary to Administrative Agent for the
benefit of Lenders.

         5.2 Collateral. Borrower and Parent shall cause full payment and
performance of the Obligation to be secured, or to continue to be secured, by

Documents creating Lender Liens, including:

         (a) Present and future accounts receivable, inventory, general

<PAGE>   46



         (b) One hundred percent (100%) of the present and future issued and
outstanding capital stock, partnership interests, and other equity interests of
all present and future Domestic Subsidiaries;

         (c) Approximately all (but not less than sixty five percent (65%)) of
the present and future issued and outstanding capital stock, partnership
interests, and other equity interests of all present and future Foreign
Subsidiaries the pledge of which would not create a material Tax obligation for
the Companies that would not otherwise exist; and

         (d) All present and future notes receivable executed by a Foreign
Subsidiary in favor of Parent or Borrower.

         5.3 Creation of Liens and Further Assurances. Borrower covenants and

created and perfected as a condition to funding any Borrowings or the issuance
of any LC. Furthermore, Borrower shall, and shall cause each other appropriate
Company to, perform the acts, duly authorize, execute, acknowledge, deliver,
file, and record any additional writings, and pay all filing fees and costs as
Administrative Agent or Required Lenders may reasonably deem appropriate or
necessary to perfect and maintain the Lender Liens and their priority and
preserve and protect the Rights of Administrative Agent and Lenders under any
Credit Document.

         5.4 Change in Tax Laws. Notwithstanding anything to the contrary set
forth in this Section 5, in the event the Tax laws regarding Foreign
Subsidiaries are changed to remove the creation of a material Tax obligation for
the Companies, each such Foreign Subsidiary may, at Borrower's discretion,
execute a Guaranty in exchange for a release of the pledge of its securities.

         5.5 Release of Collateral. Whenever Lenders no longer have any
commitment to extend credit under any Credit Document and the Obligation has
been fully paid and performed, then Administrative Agent and Lenders shall, upon
Borrower's written request and at Borrower's cost and expense, cause the Lender
Liens on all Collateral to be released and all Guaranties to be terminated and
released.

severally, represent and warrant to Administrative Agent and Lenders as follows:

         7.1 Purpose and Regulation U.

         (a) Subject to the other provisions in the Credit Documents, including
clause (b) below, initially, the Note delivered hereunder represents the renewal
and replacement of the Revolving Notes and Term Notes under the Prior Credit
Agreement, and the proceeds of any future borrowings hereunder will be used for
general corporate purposes, working capital uses in the ordinary course of
business and permitted stock repurchases.

         (b) None of the proceeds of the Revolving Facility will be used for the
purpose of purchasing or carrying any "margin stock" as defined in Regulation U
of the Board of Governors of the Federal Reserve System (12 C.F.R. Part 221), or
for the purpose of reducing or retiring any indebtedness which was originally
incurred to purchase or carry a margin stock or for any other purpose which
might constitute this transaction a "purpose credit" within the meaning of such
Regulation U. No Company is engaged in the business of extending credit for the
purpose of purchasing or carrying margin stocks. No Company, nor any Person
acting on behalf of any Company, has taken or will take any action that might
cause the Notes or any other of the Credit Documents, including this Agreement,
to violate Regulations U or any other regulations of the Board of Governors of
the Federal Reserve System or to violate Section 7 of the Securities Exchange
Act of 1934 or any rule or regulation thereunder, in each case as now in effect
or as the same may hereinafter be in effect. For the avoidance of doubt, no
proceeds of the Revolving Facility or Term Loan may be used to purchase any
securities, including without limitation, any of the Permitted Investments
described in clauses (f) through (h) of Section 9.7.

         (c) No portion of any advance or loan made hereunder shall be used
directly or indirectly to purchase ineligible securities, as defined by
applicable regulations of the Federal Reserve Board, underwritten by any
affiliate of Banc One Corporation during the underwriting period and for 30 days
thereafter.

Company is duly qualified to transact business and is in good standing as a
foreign corporation or partnership (as

of its obligations under those Credit Documents (i) are within its corporate or
partnership power (as applicable), (ii) have been duly authorized by all
necessary corporate or partnership action (as applicable), (iii) require no

         7.5 Binding Effect. Upon execution by each Company of each Credit

legal and binding obligation of each such party, enforceable against each such
party in accordance with that Credit Document's terms except as that

equity.

proceedings under ERISA to terminate that plan, deliver a certificate of a
Responsible Officer of Borrower setting forth details as to that reportable
event and the action which Borrower or an ERISA Affiliate, as the case may be,
proposes to take with respect to it, together with a copy of any notice of that
reportable event which may be required to be filed with the PBGC, or any notice
delivered by the PBGC evidencing its intent to institute those proceedings or

and status of any Litigation or Environmental Liability that if determined

required), each Company shall allow Administrative Agent or any Lender (or their
respective Representatives) to inspect any of that Company's properties, to
review reports, files and other records and to make and take away copies, to
conduct tests or investigations and to discuss any of its affairs, conditions
and finances with the Company's Representatives and with other creditors of the
Company from time to time, during reasonable business hours (but during the

SETTLEMENT, DAMAGES, JUDGMENTS, PENALTIES, COURT COSTS, LIABILITIES AND
OBLIGATIONS, AND ALL PRESENT AND FUTURE COSTS, EXPENSES AND DISBURSEMENTS
(INCLUDING ALL REASONABLE ATTORNEYS' FEES AND EXPENSES WHETHER OR NOT SUIT OR
OTHER PROCEEDING EXISTS OR ANY INDEMNITEE IS PARTY TO ANY SUIT OR OTHER
PROCEEDING) IN ANY WAY RELATED TO ANY OF THE FOREGOING, THAT MAY AT ANY TIME BE
IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST, ANY INDEMNITEE AND IN ANY WAY
RELATING TO OR ARISING OUT OF ANY (1) CREDIT DOCUMENT OR TRANSACTION
CONTEMPLATED BY ANY CREDIT DOCUMENT, (2) ENVIRONMENTAL LIABILITY IN ANY WAY
RELATED TO ANY COMPANY, OR ACT, OMISSION, STATUS, OWNERSHIP, OR OTHER
RELATIONSHIP, CONDITION, OR CIRCUMSTANCE CONTEMPLATED BY, CREATED UNDER, OR
ARISING PURSUANT TO OR IN CONNECTION WITH ANY CREDIT DOCUMENT, OR (3)

INDEMNITEE'S INVESTIGATION, ACTUAL OR CONSTRUCTIVE KNOWLEDGE, COURSE OF DEALING,
OR WAIVER.

         (d) However, no Indemnitee is entitled to be indemnified under the
Credit Documents for its own fraud, gross negligence, or wilful misconduct.

         (e) Although failure to do so does not reduce or impair any
Indemnitor's obligations under this section, each Indemnitee shall promptly
notify Borrower of any event about which the Indemnitee has received written
notice and that is reasonably likely to result in any Indemnified Liability.
Each Indemnitor may, at its own cost and expense, participate in the defense in
any proceeding involving any Indemnified Liability. If no Event of Default or
Potential Default exists, Indemnitors may assume the defense in that proceeding
on behalf of the applicable Indemnitees, including the employment of counsel if
first approved (which approval may not be unreasonably withheld) by the
applicable Indemnitees. If Indemnitors assume any defense, they shall keep the
applicable Indemnitees fully advised of the status of, and shall consult with,
and receive the concurrence of, those Indemnitees before taking any material
position in respect of, that proceeding. If Indemnitors consent, if an Event of
Default, Potential Default or Material Adverse Event exists or if any Indemnitee
reasonably determines that an actual conflict of interests exists between
Indemnitors and that Indemnitee with respect to the subject matter of the
proceeding or that Indemnitors are not diligently pursuing the defense, then (i)
that Indemnitee may, at Indemnitors' joint and several expense, employ counsel
to represent that Indemnitee that is separate from counsel for Indemnitors or
any other Person in that proceeding and (ii) Indemnitors are no longer entitled
to assume the defense on behalf of that Indemnitee. No Indemnitor may agree to
the settlement of any Indemnified Liability, or any matters or issues material
to or necessary for the resolution of any such liability, without the prior
written consent of the applicable Indemnitees unless, as agreed to in writing by
an Indemnitee, that settlement fully relieves those Indemnitees of any liability
whatsoever for that Indemnified Liability. If an Indemnitee agrees to the
settlement of any Indemnified Liability without the prior written consent of
Indemnitors (which consent may not be unreasonably withheld), then Indemnitors
are no longer obligated for that Indemnified Liability in respect of that
Indemnitee.

         (f) THE PROVISIONS OF AND INDEMNIFICATION AND OTHER UNDERTAKINGS UNDER
THIS SECTION SURVIVE THE FORECLOSURE OF ANY LENDER LIEN OR ANY TRANSFER IN LIEU
OF THAT FORECLOSURE, THE SALE OR OTHER TRANSFER OF ANY COLLATERAL OR REAL
PROPERTY TO ANY PERSON, THE SATISFACTION OF THE OBLIGATION, THE TERMINATION OF
THE CREDIT DOCUMENTS AND THE RELEASE OF ANY OR ALL LENDER LIENS.

         (g) BORROWER AND EACH OTHER COMPANY ACKNOWLEDGE THAT THE VARIOUS
INDEMNITIES CONTAINED IN THIS AGREEMENT INCLUDE PROVISIONS INDEMNIFYING AND
HOLDING HARMLESS ADMINISTRATIVE AGENT, LENDERS, THEIR AFFILIATES AND THEIR
REPRESENTATIVES FOR, AMONG OTHER THINGS, THE ORDINARY NEGLIGENCE OF THE
INDEMNITEE. BORROWER AND EACH OTHER COMPANY AGREE THAT THE INDEMNITY PROVISIONS
CONTAINED HEREIN ARE HIGHLIGHTED TO CLEARLY IDENTIFY THE INDEMNITY PROVISIONS
AND, THEREFORE, ARE SO CONSPICUOUS THAT BORROWER AND EACH OTHER COMPANY HAVE
FAIR NOTICE OF THE EXISTENCE AND CONTENTS OF SUCH PROVISIONS AND WAIVE ANY RIGHT
THEY MAY HAVE TO CLAIM OTHERWISE.

         8.14 Post-Closing Covenants.

         (a) Borrower shall cooperate with Administrative Agent's counsel in a
timely manner to obtain, complete, file or otherwise complete all collateral
documents not obtained on the Closing Date.

         (b) Within thirty (30) days after Closing, Borrower will provide to
Administrative Agent a Mortgage in form and substance acceptable to
Administrative Agent (the "OHIO MORTGAGE"), duly executed, acknowledged and
delivered by Diamond, and duly recorded in the appropriate real property
records, creating a first and prior Lender Lien on approximately 9.21 acres of
land and the improvements located thereon, owned in fee simple by Diamond, being
Lots 2, 3 and 5, Greenfield Crossroads Subdivision, Greenfield Township,
Fairfield County, Ohio with addressees of 4460 Columbus Road NW, Carroll, Ohio
43112 and the main plant at 4465 Coonpath Rd, Carroll, Ohio 43112 (the "OHIO
FACILITY") to secure payment and performance of the Obligation, together with
(i) a mortgagee policy of title insurance in an amount acceptable to
Administrative Agent and issued by a title insurance company acceptable to
Administrative Agent insuring that the Lien created by the Ohio Mortgage creates
a valid, first and prior Lien on the Ohio Facility, subject to no prior or equal
Liens (other than easements, building restrictions, liens for taxes not yet due
and payable and other similar encumbrances which are not of a material nature
and do not secure Debt), (ii) a current, ALTA as-built boundary survey of the
real estate and improvements comprising the Ohio Facility reflecting no material

Net Worth shall not at any time be less than the sum of (a) Seventy Three
Million Dollars ($73,000,000) plus (b) an amount equal to seventy five percent

usual and customary brokerage and after related costs and expenses) proceeds

December 31, 1999, 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.

         10.4 Capital Expenditures. For any fiscal year of Borrower, Capital
Expenditures for the acquisition, construction, improvement or replacement of
land, buildings, equipment or other fixed or capital 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) Four Million Dollars ($4,000,000) for the

         11.6 Misrepresentation. Any representation or warranty made by any
Company in any Credit Document at any time proves to have been false or
incorrect in any material respect when made.

         11.7 Ownership of Other Companies. Except as a result of transactions

percent (75%) of Parent's or Borrower's, as the case may be, board of directors;

immediately or only after the passage of time), directly or indirectly, of more
than twenty five percent (25%) of the total voting power of the outstanding
capital stock (having full voting power) of Parent (for the purpose of this
clause (ii), such person shall be deemed to beneficially own any such capital
stock (having full voting power) of a specified

five percent (25%) of the total voting power of the capital stock (having full
voting power) of such parent corporation); (iii) the sale, transfer,

payment dates, or (iii) any of that Funded Debt is declared to be due and

         11.11 Validity and Enforceability. This Agreement, any Note, Guaranty
or any other Credit Document ceases to be in full force and effect or is
declared to be null and void, or the validity or enforceability of any Credit
Document or Lender Lien is contested by any Company or any other Person, or any
Company or any other Person asserts the absence of, or denies that it has, any
liability or obligations under any Credit Document to which it is a party except
in accordance with that document's express provisions, or any Lender Lien shall

         11.12 Material Agreement Default or Cancellation. The default under, or
breach or cancellation of, any agreement or other contractual arrangement to

significant impairment of (a) the ability of Borrower or any other Company to
perform any of its payment or other material obligations under any Credit
Document or (b) the ability of Administrative Agent or Lenders to enforce any of
those obligations or any of their respective Rights under the Credit Documents,

condition of the Borrower or of the Companies as a whole, as represented to
Lenders in the Financials then most recently received by them or (iii) event or
circumstance that could result in an Event of Default or Potential Default
pursuant to Sections 11.1 through 11.13 (inclusive) or Section 11.14.

         11.13 LCs. Administrative Agent is served with, or becomes subject to,
a court order, injunction, or other process or decree restraining or seeking to
restrain it from paying any amount under any LC and either


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 62               ULTRAK OPERATING, L.P.

<PAGE>   69




(a) a drawing has occurred under the LC, and Borrower has refused to reimburse
Administrative Agent for payment, or (b) the expiration date of the LC has
occurred, but the Right of the beneficiary to draw under the LC has been
extended past the expiration date in connection with the pendency of the related
court action or proceeding, and Borrower has failed to deposit with
Administrative Agent cash collateral in an amount equal to Administrative
Agent's maximum exposure under the LC.

SECTION 12. RIGHTS AND REMEDIES.

         12.1 Remedies Upon Event of Default.

         (a)  Debtor Relief. If an Event of Default exists under Section 11.3,
the commitment to extend credit under this Agreement automatically terminates
and the entire unpaid principal balance of the Obligation, together with all
interest accrued thereon, and all other amounts then accrued and unpaid,
automatically become and shall be due and payable without any action of any kind
whatsoever.

         (b)  Other Events of Default. If any Event of Default exists,
Administrative Agent may (with the consent of, and must, upon the request of
Required Lenders), do any one or more of the following: (i) If the maturity of
the Obligation has not already been accelerated under Section 12.1(a), declare
the entire unpaid principal balance of all or any part of the Obligation,
together with all interest accrued thereon, and all other amounts then accrued
and unpaid, immediately due and payable, whereupon it is due and payable; (ii)
terminate the commitments of Lenders to extend credit under this Agreement;
(iii) reduce any claim to judgment; (iv) demand payment of an amount equal to
the LC Exposure then existing and retain as collateral for the LC Exposure any
amounts received from any Company, from any property of any Company, through
offset or otherwise; and (v) exercise any and all other legal or equitable
Rights afforded by the Credit Documents, by applicable Laws or otherwise at law
or in equity.

         (c)  Offset. If an Event of Default exists, to the extent not
prohibited by applicable Laws, each Lender may exercise the Rights of offset and
banker's lien against each and every account and other property, or any interest
therein, which any Company may now or hereafter have with, or which is now or
hereafter in the possession of, that Lender to the extent of the full amount of
the Obligation owed to that Lender.

         12.2 Company Waivers. To the extent not prohibited by applicable Laws,
Borrower and (pursuant to its Guaranty or its execution and delivery of, or
consent to, any other Credit Document) each other Company waives, in respect to
any action taken by Administrative Agent or Lenders at any time and from time to
time pursuant to Section 12.1, presentment, demand for payment, protest,
acceleration, notice of protest and nonpayment, NOTICE OF INTENTION TO
ACCELERATE, NOTICE OF ACCELERATION, and all other notices and acts, and agrees
that its liability with respect to all or any part of the Obligation is not
affected by any renewal or extension in the time of payment of all or any part
of the Obligation, by any indulgence, increase or other modification to, or by
any release or change in any security for the payment of, all or any part of the
Obligation.

         12.3 Performance by Administrative Agent. If any Company's covenant,
duty or agreement is not performed in accordance with the terms of the Credit
Documents, Administrative Agent may at its option (but subject to the approval
of Required Lenders), perform or attempt to perform that covenant, duty or
agreement on behalf of that Company, and any amount expended by or on behalf of
Administrative Agent in its performance or attempted performance is payable by
the Companies, jointly and severally, to Administrative Agent on demand, becomes
part of the Obligation, and bears interest on the portion thereof from time to
time unpaid at the Default Rate from the date of Administrative Agent's
expenditure until paid. However, Administrative Agent does not assume and shall
never have, except by its express written consent, any liability or
responsibility for the performance of any Company's covenants, duties or
agreements.


                                           AMENDED AND RESTATED CREDIT AGREEMENT

<PAGE>   70




         12.4 Not in Control. Nothing in any Credit Document gives or may be
deemed to give to Administrative Agent or any Lender the Right to exercise
control over any Company's Real Property, other assets, affairs or management or
to preclude or interfere with any Company's compliance with any Law or require
any act or omission by any Company that may be harmful to Persons or property.
Any "Material Adverse Event" or other materiality or substantiality qualifier of
any representation, warranty, covenant, agreement or other provision of any
Credit Document is included for credit documentation purposes only and does not
imply and should not be deemed to mean that Administrative Agent or any Lender
acquiesces in any non-compliance by any Company with any applicable Law,
document, or otherwise or does not expect the Companies to promptly, diligently
and continuously carry out all appropriate removal, remediation, compliance,
closure or other activities required or appropriate in accordance with all
Environmental Laws. Administrative Agent's and Lenders' power is limited to the
Rights provided in, or referred to by, the Credit Documents. All of those Rights
exist solely to preserve and protect the Collateral and to assure payment and
performance of the Obligation in accordance with the terms of the Credit
Documents, and may be exercised in a manner determined to be appropriate by
Administrative Agent or Lenders in their sole respective good faith business
judgment.

         12.5 Course of Dealing. The acceptance by Administrative Agent or
Lenders of any partial payment on the Obligation is not a waiver of any Event of
Default then existing. No waiver by Administrative Agent, Required Lenders or
Lenders of any Event of Default is a waiver of any other then-existing or
subsequent Event of Default. No delay or omission by Administrative Agent,
Required Lenders or Lenders in exercising any Right under the Credit Documents
impairs that Right or is a waiver thereof or any acquiescence therein, nor will
any single or partial exercise of any Right preclude other or further exercise
thereof or the exercise of any other Right under the Credit Documents or
otherwise.

         12.6 Cumulative Rights. All Rights available to Administrative Agent,
Required Lenders and Lenders under the Credit Documents are cumulative of and in
addition to all other Rights granted to Administrative Agent, Required Lenders
and Lenders at law or in equity, whether or not the Obligation is due and
payable and whether or not Administrative Agent, Required Lenders or Lenders
have instituted any suit for collection, foreclosure, or other action in
connection with the Credit Documents.

         12.7 Application of Proceeds. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation according to Section 3.

         12.8 Certain Proceedings. Borrower shall promptly execute and deliver,
or cause the execution and delivery of, all applications, certificates,
instruments, registration statements, and all other documents and papers
Administrative Agent or Required Lenders reasonably request in connection with
the obtaining of any consent, approval, registration (other than securities law
registrations), qualification, permit, license or authorization of any
Governmental Authority or other Person necessary or appropriate for the
effective exercise of any Rights under the Credit Documents. Because Borrower
agrees that Administrative Agent's and Required Lenders' remedies under
applicable Laws for failure of Borrower to comply with the provisions of this
section would be inadequate and that failure would not be adequately compensable
in damages, Borrower agrees that the covenants of this section may be
specifically enforced.

         12.9 Expenditures by Administrative Agent or Lenders. Any sums spent by
Administrative Agent or any Lender in the exercise of any Right under any Credit
Document is payable by the Companies to


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 64               ULTRAK OPERATING, L.P.

<PAGE>   71




Administrative Agent within 15 Business Days of written demand, becomes part of
the Obligation, and bears interest on the portion thereof from time to time
unpaid at the Default Rate from the date spent until the date repaid.

         12.10 Diminution in Value of Collateral. Neither Administrative Agent
nor any Lender has any liability or responsibility whatsoever for any diminution
in or loss of value of any collateral now or in the future securing payment or
performance of any of the Obligation (other than diminution in or loss of value
caused by its own gross negligence or willful misconduct).

SECTION 13. ADMINISTRATIVE AGENT AND LENDERS.

         13.1 Administrative Agent.

         (a)  Appointment. Each Lender appoints Administrative Agent (including
each successor Administrative Agent in accordance with this Section 13) as its
nominee and agent to act in its name and on its behalf (and Administrative Agent
and each such successor accepts that appointment): (i) To act as its nominee and
on its behalf in and under all Credit Documents; (ii) to arrange the means
whereby its funds are to be made available to Borrower under the Credit
Documents; (iii) to take any action that it properly requests under the Credit
Documents (subject to the concurrence of other Lenders as may be required under
the Credit Documents); (iv) to receive all documents and items to be furnished
to it under the Credit Documents; (v) to be the secured party, mortgagee,
beneficiary, recipient and similar party in respect of any collateral for the
benefit of Lenders; (vi) to promptly distribute to it all material information,
requests, documents, and items received from Borrower under the Credit
Documents; (vii) to promptly distribute to it its ratable part of each payment
or prepayment (whether voluntary, as proceeds of collateral upon or after
foreclosure, as proceeds of insurance thereon, or otherwise) in accordance with
the terms of the Credit Documents; and (viii) to deliver to the appropriate
Persons requests, demands, approvals, and consents received from it. However,
Administrative Agent may not be required to take any action that exposes it to
personal liability or that is contrary to any Credit Document or applicable
Laws.

         (b)  Successor. Administrative Agent may assign all of its Rights and
obligations as Administrative Agent under the Credit Documents to any of its
Affiliates, which Affiliate shall then be the successor Administrative Agent
under the Credit Documents. Administrative Agent may also voluntarily resign and
shall resign upon the request of Required Lenders for cause (i.e.,
Administrative Agent is continuing to fail to perform its responsibilities as
Administrative Agent under the Credit Documents). If the initial or any
successor Administrative Agent ever ceases to be a party to this Agreement or if
the initial or any successor Administrative Agent ever resigns (whether
voluntarily or at the request of Required Lenders), then Required Lenders shall
(which, if no Event of Default or Potential Default exists, is subject to
Borrower's approval that may not be unreasonably withheld) appoint the successor
Administrative Agent from among Lenders (other than the resigning Administrative
Agent). If Required Lenders fail to appoint a successor Administrative Agent
within 30 days after the resigning Administrative Agent has given notice of
resignation or Required Lenders have removed the resigning Administrative Agent,
then the resigning Administrative Agent may, on behalf of Lenders, appoint a
successor Administrative Agent, which must be a commercial bank having a
combined capital and surplus of at least One Billion Dollars ($1,000,000,000)
(as shown on its most recently published statement of condition). Upon its
acceptance of appointment as successor Administrative Agent, the successor
Administrative Agent succeeds to and becomes vested with all of the Rights of
the prior Administrative Agent, and the prior Administrative Agent is discharged
from its duties and obligations of Administrative Agent under the Credit
Documents (but, when used in connection with LCs issued and outstanding before
the appointment of the successor Administrative Agent, "Administrative Agent"
shall


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 65               ULTRAK OPERATING, L.P.

<PAGE>   72




continue to refer solely to the prior Administrative Agent, but any LCs issued
or renewed after the appointment of any successor Administrative Agent shall be
issued or renewed by the successor Administrative Agent), and each Lender shall
execute the documents that any Lender, the resigning or removed Administrative
Agent, or the successor Administrative Agent reasonably request to reflect the
change. After any Administrative Agent's resignation or removal as
Administrative Agent under the Credit Documents, the provisions of this section
inure to its benefit as to any actions taken or not taken by it while it was
Administrative Agent under the Credit Documents.

         (c) Rights as Lender. Administrative Agent, in its capacity as a
Lender, has the same Rights under the Credit Documents as any other Lender and
may exercise those Rights as if it were not acting as Administrative Agent. The
term "LENDER", unless the context otherwise indicates, includes Administrative
Agent. Administrative Agent's resignation or removal does not impair or
otherwise affect any Rights that it has or may have in its capacity as an
individual Lender. Each Lender and Borrower agree that Administrative Agent is
not a fiduciary for Lenders or for Borrower but is simply acting in the capacity
described in this Agreement to alleviate administrative burdens for Borrower and
Lenders, that Administrative Agent has no duties or responsibilities to Lenders
or Borrower except those expressly set forth in the Credit Documents, and that
Administrative Agent in its capacity as a Lender has the same Rights as any
other Lender.

         (d) Other Activities. Administrative Agent or any Lender may now or in
the future be engaged in one or more loan, letter of credit, leasing, hedging
agreement, or other financing transactions with Borrower or other Companies, act
as trustee or depositary for Borrower or other Companies, or otherwise be
engaged in other transactions with Borrower or other Companies (collectively,
the "OTHER ACTIVITIES") not the subject of the Credit Documents. Without
limiting the Rights of Lenders specifically set forth in the Credit Documents,
neither Administrative Agent nor any Lender is responsible to account to the
other Lenders for those other activities, and no Lender shall have any interest
in any other Lender's activities, any present or future guaranties by or for the
account of Borrower or other Companies that are not contemplated by or included
in the Credit Documents, any present or future offset exercised by
Administrative Agent or any Lender in respect of those other activities, any
present or future property taken as security for any of those other activities,
or any property now or hereafter in Administrative Agent's or any other Lender's
possession or control that may be or become security for the obligations of
Borrower or other Companies arising under the Credit Documents by reason of the
general description of indebtedness secured or of property contained in any
other agreements, documents, or instruments related to any of those other
activities (but, if any payments in respect of those guaranties or that property
or the proceeds thereof is applied by Administrative Agent or any Lender to
reduce the Obligation, then each Lender is entitled to share ratably in the
application as provided in the Credit Documents).

         13.2 Expenses. Each Lender shall pay its Pro Rata Part of any
reasonable expenses (including court costs, reasonable attorneys' fees and other
costs of collection) incurred by Administrative Agent (while acting in such
capacity) in connection with any of the Credit Documents if Administrative Agent
is not reimbursed from other sources within 30 days after incurrence. Each
Lender is entitled to receive its Pro Rata Part of any reimbursement that it
makes to Administrative Agent if Administrative Agent is subsequently reimbursed
from other sources.

         13.3 Proportionate Absorption of Losses. Except as otherwise provided
in the Credit Documents, nothing in the Credit Documents gives any Lender any
advantage over any other Lender insofar as the Obligation is concerned or
relieves any Lender from ratably absorbing any losses sustained with respect to
the Obligation (except to the extent unilateral actions or inactions by any
Lender result in Borrower or any other Company having any credit, allowance,
setoff, defense, or counterclaim solely with respect to all or any part of that
Lender's Pro Rata Part of the Obligation).

         13.4 Delegation of Duties; Reliance. Lenders may perform any of their
duties or exercise any of their Rights under the Credit Documents by or through
Administrative Agent, and Lenders and Administrative Agent may perform any of
their duties or exercise any of their Rights under the Credit Documents by or
through their respective Representatives. Administrative Agent, Lenders, and
their respective Representatives (a) are entitled to rely upon (and shall be
protected in relying upon) any written or oral statement believed by it or them
to be genuine and correct and to have been signed or made by the proper Person
and, with respect to legal matters, upon opinion of counsel selected by
Administrative Agent or that Lender (but nothing in this clause (a) permits
Administrative Agent to rely on (i) oral statements if a writing is required by
this Agreement or (ii) any other writing if a specific writing is required by
this Agreement), (b) are entitled to deem and treat each Lender as the owner and
holder of its portion of the Obligation for all purposes until, written notice
of the assignment or transfer is given to and received by Administrative Agent
(and any request, authorization, consent, or approval of any Lender is
conclusive and binding on each subsequent holder, assignee, or transferee of or
Participant in that Lender's portion of the Obligation until that notice is
given and received), (c) are not deemed to have notice of the occurrence of an
Event of Default unless a responsible officer of Administrative Agent, who
handles matters associated with the Credit Documents and transactions
thereunder, has actual knowledge or Administrative Agent has been notified by a
Lender or Borrower, and (d) are entitled to consult with legal counsel
(including counsel for Borrower), independent accountants, and other experts
selected by Administrative Agent and are not liable for any action taken or not
taken in good faith by it in accordance with the advice of counsel, accountants,
or experts.

         13.5 Limitation of Administrative Agent's Liability.

         (a)  Exculpation. Neither Administrative Agent nor any of its
Affiliates or Representatives will be liable for any action taken or omitted to
be taken by it or them under the Credit Documents in good faith and believed by
it or them to be within the discretion or power conferred upon it or them by the
Credit Documents or be responsible for the consequences of any error of judgment
(except for fraud, gross negligence, or willful misconduct), and neither
Administrative Agent nor any of its Affiliates or Representatives has a
fiduciary relationship with any Lender by virtue of the Credit Documents (but
nothing in this Agreement negates the obligation of Administrative Agent to
account for funds received by it for the account of any Lender).

         (b)  Indemnity. Unless indemnified to its satisfaction against loss,
cost, liability, and expense, Administrative Agent may not be compelled to do
any act under the Credit Documents or to take any action toward the execution or
enforcement of the powers thereby created or to prosecute or defend any suit in
respect of the Credit Documents. If Administrative Agent requests instructions
from Lenders, or Required Lenders, as the case may be, with respect to any act
or action in connection with any Credit Document, Administrative Agent is
entitled to refrain (without incurring any liability to any Person by so
refraining) from that act or action unless and until it has received
instructions. In no event, however, may Administrative Agent or any of its
Representatives be required to take any action that it or they determine could
incur for it or them criminal or onerous civil liability. Without limiting the
generality of the foregoing, no Lender has any right of action against
Administrative Agent as a result of Administrative Agent's acting or refraining
from acting under this Agreement in accordance with instructions of Required
Lenders.

         (c)  Reliance. Administrative Agent is not responsible to any Lender or
any Participant for, and each Lender represents and warrants that it has not
relied upon Administrative Agent in respect of, (i) the creditworthiness of any
Company and the risks involved to that Lender, (ii) the effectiveness,
enforceability,


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 67               ULTRAK OPERATING, L.P.

<PAGE>   74




genuineness, validity, or the due execution of any Credit Document (except by
Administrative Agent), (iii) any representation, warranty, document,
certificate, report, or statement made therein (except by Administrative Agent)
or furnished thereunder or in connection therewith, (iv) the adequacy of any
collateral now or hereafter securing the Obligation or the existence, priority,
or perfection of any Lien now or hereafter granted or purported to be granted on
the collateral under any Credit Document, or (v) observation of or compliance
with any of the terms, covenants, or conditions of any Credit Document on the
part of any Company. EACH LENDER AGREES TO INDEMNIFY ADMINISTRATIVE AGENT AND
ITS REPRESENTATIVES AND HOLD THEM HARMLESS FROM AND AGAINST (BUT LIMITED TO SUCH
LENDER'S COMMITMENT PERCENTAGE OF) ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, REASONABLE EXPENSES, AND
REASONABLE DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER THAT MAY BE IMPOSED
ON, ASSERTED AGAINST, OR INCURRED BY THEM IN ANY WAY RELATING TO OR ARISING OUT
OF THE CREDIT DOCUMENTS OR ANY ACTION TAKEN OR OMITTED BY THEM UNDER THE CREDIT
DOCUMENTS IF ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES ARE NOT REIMBURSED FOR
SUCH AMOUNTS BY ANY COMPANY. ALTHOUGH ADMINISTRATIVE AGENT AND ITS
REPRESENTATIVES HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR
THEIR OWN ORDINARY NEGLIGENCE, ADMINISTRATIVE AGENT AND ITS REPRESENTATIVES DO
NOT HAVE THE RIGHT TO BE INDEMNIFIED UNDER THIS AGREEMENT FOR ITS OR THEIR OWN
FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT.

         13.6 Event of Default. While an Event of Default exists, Lenders agree
to promptly confer in order that Required Lenders or Lenders, as the case may
be, may agree upon a course of action for the enforcement of the Rights of
Lenders. Administrative Agent is entitled to act or refrain from taking any
action (without incurring any liability to any Person for so acting or
refraining) unless and until it has received instructions from Required Lenders.
In actions with respect to any Company's property, Administrative Agent is
acting for the ratable benefit of each Lender.

         13.7 Collateral Matters.

         (a) General Authorization. Each Lender authorizes and directs
Administrative Agent to enter into the Credit Documents for the Lender Liens and
agrees that any action taken by Administrative Agent concerning any Collateral
(with the consent or at the request of Required Lenders) in accordance with any
Credit Document, that Administrative Agent's exercise (with the consent or at
the request of Required Lenders) of powers concerning the Collateral in any
Credit Document and that all other reasonably incidental powers are authorized
and binding upon all Lenders.

         (b) Maintaining Lender Liens. Administrative Agent is authorized on
behalf of all Lenders, without the necessity of any notice to or further consent
from any Lender, from time to time before an Event of Default or Potential
Default, to take any action with respect to any Collateral or Credit Documents
related to Collateral that may be necessary to perfect and maintain perfected
the Lender Liens upon the Collateral.

         (c) Limitation of Obligations. Except to use the same standard of care
that it ordinarily uses for collateral for its sole benefit, Administrative
Agent has no obligation whatsoever to any Lender or to any other Person to
assure that the Collateral exists or is owned by any Company or is cared for,
protected, or insured or has been encumbered or that the Lender Liens have been
properly or sufficiently or lawfully created, perfected, protected, or enforced
or are entitled to any particular priority.

         (d) Standard of Care. Administrative Agent shall exercise the same care
and prudent judgment with respect to the Collateral and the Credit Documents as
it normally and customarily exercises in respect of similar collateral and
security documents.

<PAGE>   75




         (e) Release of Collateral. Lenders irrevocably authorize Administrative
Agent, at its option and in its discretion, to release any Lender Lien upon any
Collateral (i) upon full payment of the Obligation, (ii) constituting property
being disposed of as permitted under any Credit Document, (iii) constituting
property in which no Company owned any interest at the time the Lender Lien was
granted or at any time after that, (iv) constituting property leased to any
Company under a lease that has expired or been terminated in a transaction
permitted under the Credit Documents or is about to expire and that has not
been, and is not intended by that Company to be, renewed, (v) consisting of an
instrument evidencing Debt pledged to Administrative Agent (for the benefit of
Lenders), if the underlying Debt has been paid in full, or (vi) if approved,
authorized, or ratified in writing by Lenders. Upon request by Administrative
Agent at any time, Lenders shall confirm in writing Administrative Agent's
authority to release particular types or items of Collateral under this clause
(e).

         13.8 Limitation of Liability. No Lender or any Participant will incur
any liability to any other Lender or Participant except for acts or omissions in
bad faith, and neither Administrative Agent nor any Lender or Participant will
incur any liability to any other Person for any act or omission of any other
Lender or any Participant.

         13.9 Relationship of Lenders. The Credit Documents do not create a
partnership or joint venture among Administrative Agent and Lenders or among
Lenders.

         13.10 American National Bank Option To Purchase Lender Position. In the
event Administrative Agent recommends a course of action, amendment,
modification or waiver hereunder, and, if any Lender (a "NON-CONSENTING LENDER")
does not approve such course of action, amendment, modification or waiver within
thirty (30) days after requested to do so by Administrative Agent (the "REQUEST
PERIOD"), then, at any time during the sixty-day period (the "OPTION PERIOD")
after the end of the Request Period, American National shall the absolute right
and option, exercised by notice to the Non-Consenting Lender given on or before
the end of the Option Period, to purchase the Note held by the Non-Consenting
Lender, and all Liens and Rights of the Non-Consenting Lender related thereto,
for an amount equal to principal, interest, fees and expenses due and owing with
respect to the Non-Consenting Lender's Note on the date of purchase. The
consummation of the purchase will be held within ten (10) days after the
exercise notice is sent to the Non-Consenting Lender and will be subject to and
governed by the last sentence of Section 14,12(c), and, at the time of purchase,
the Non-Consenting Lender, as assignor, and American National, as assignee will
execute and deliver a Note and Lien Assignment.

         13.11 Benefits of Agreement. None of the provisions of this Section 13
(13.1-13.10, inclusive) inure to the benefit of any Company or any other Person
except Administrative Agent and Lenders. Therefore, no Company or any other
Person is entitled to rely upon, or entitled to raise as a defense, in any
manner whatsoever, the failure of Administrative Agent or any Lender to comply
with these provisions.

SECTION 14. MISCELLANEOUS.

         14.1 Nonbusiness Days. Any payment or action that is due under any
Credit Document on a non-Business Day may be delayed until the next-succeeding
Business Day (but interest shall continue to accrue on any applicable payment
until payment is in fact made) unless the payment concerns a LIBOR Rate
Borrowing or a Eurocurrency Borrowing, in which case if the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

         14.2 Communications. Unless otherwise specifically provided, whenever
any Credit Document requires or permits any consent, approval, notice, request
or demand from one party to another, communication


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 69               ULTRAK OPERATING, L.P.

<PAGE>   76




must be in writing (which may be by telex or fax) to be effective and shall be
deemed to have been given (i) if by telex, when transmitted to the appropriate
telex number and the appropriate answer back is received, (ii) if by fax, when
transmitted to the appropriate fax number (and all communications sent by fax
must be confirmed promptly thereafter by telephone; but any requirement in this
parenthetical shall not affect the date when the fax shall be deemed to have
been delivered), (iii) if by mail, on the third Business Day after it is
enclosed in an envelope and properly addressed, stamped, sealed and deposited in
the appropriate official postal service, or (iv) if by any other means, when
actually delivered. Until changed by notice pursuant to this Agreement, the
address (and fax number) for Administrative Agent, each initial Lender and
Borrower is stated beside their respective signatures to this Agreement. All
borrowing requests and conversion notices relating to Eurocurrency Borrowings
shall be delivered to the address for the Eurocurrency Lending Installation,
with no requirement that they also be delivered to Administrative Agent's
Chicago, Illinois office. All other notices, certificates and other items
required to be delivered under this Agreement or the other Credit Documents
shall be delivered to the address for the Administrative Agent and Lenders as
set forth herein, with no requirement that they also be delivered to the
Eurocurrency Lending Installation. Any required or optional delivery under the
Credit Documents shall only be deemed made if delivered in accordance with the
above-described requirements (i.e. no delivery to the Eurocurrency Lending
Installation of items other than borrowing requests and conversion notices
relating to Eurocurrency Borrowings shall be deemed made in accordance with the
requirements of the Credit Documents, and no delivery to the Administrative
Agent or any Lender of borrowing requests and conversion notices relating to
Eurocurrency Borrowings shall be deemed made in accordance with the requirements
of the Credit Documents). The address (and fax number) for each Lender who
becomes party to this Agreement after the Closing Date shall be stated beside
its name on the then most recently amended Schedule 2.

         14.3 Form and Number of Documents. The form, substance and number of
counterparts of each writing to be furnished under this Agreement must be
reasonably satisfactory to Administrative Agent and its counsel.

         14.4 Exceptions to Covenants. No Company may take or fail to take any
action that is permitted as an exception to any of the covenants contained in
any Credit Document if that action or omission would result in the breach of any
other covenant contained in any Credit Document.

         14.5 Survival. All covenants, agreements, undertakings,
representations, and warranties made in any of the Credit Documents survive all
closings under the Credit Documents and, except as otherwise indicated, are not
affected by any investigation made by any party.

         14.6 Governing Laws. Unless otherwise stated in any Credit Document,
the Laws of the State of Texas and of the United States govern the Rights and
duties of the parties to the Credit Documents and the validity, construction,
enforcement, and interpretation of the Credit Documents.

         14.7 Invalid Provisions. Any provision in any Credit Document held to
be illegal, invalid or unenforceable is fully severable; the appropriate Credit
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision. Administrative Agent, Lenders
and each Company party to the affected Credit Document agree to negotiate, in
good faith, the terms of a replacement provision as similar to the severed
provision as may be possible and be legal, valid and enforceable.

         14.8 Conflicts Between Credit Documents. The provisions of this
Agreement control if in conflict (i.e., the provisions contradict each other as
opposed to a Credit Document containing additional provisions not in conflict)
with the provisions of any other Credit Document.


                                           AMENDED AND RESTATED CREDIT AGREEMENT

<PAGE>   77




         14.9 Discharge and Certain Reinstatement. The obligations of Borrower
and the other Companies under the Credit Documents remain in full force and
effect until Lenders have no commitment to extend credit under the Credit
Documents and the Obligation is fully paid (except for provisions under the
Credit Documents which by their terms expressly survive payment of the
Obligation and termination of the Credit Documents). If any payment under any
Credit Document is ever rescinded or must be restored or returned for any
reason, then all Rights and obligations under the Credit Documents in respect of
that payment are automatically reinstated as though the payment had not been
made when due.

         14.10 Amendments, Consents, Conflicts, and Waivers.

         (a) Required Lenders. Unless otherwise specifically provided (i) the
provisions of this Agreement may be amended, modified, or waived, only by an
instrument in writing executed by Borrower, Administrative Agent, and Required
Lenders and supplemented only by documents delivered or to be delivered in
accordance with the express terms of this Agreement, and (ii) the other Credit
Documents may only be the subject of an amendment, modification, or waiver that
has been approved by Required Lenders and Borrower.

         (b) All Lenders. Any amendment to or consent or waiver under this
Agreement or any Credit Document that purports to accomplish any of the
following must be by an instrument in writing executed by Borrower and
Administrative Agent and executed (or approved, as the case may be) by each
Lender: (i) Extends the due date or decreases the amount of any scheduled
payment or amortization of the Obligation beyond the date specified in the
Credit Documents; (ii) decreases any rate or amount of interest, fees, or other
sums payable to Administrative Agent or Lenders under this Agreement (except
such reductions as are contemplated by this Agreement); (iii) changes the
definition of "COMMITMENT," "COMMITMENT PERCENTAGE," "REQUIRED LENDERS," or "PRO
RATA PART," or the percentages in the definition of "BORROWING BASE"; (iv)
increases any one or more Lenders' Commitment; (v) waives compliance with,
amends, or fully or partially releases -- except as expressly provided in the
Credit Documents or for when a Company merges into another Person or dissolves
when specifically permitted in the Credit Documents -- any Guaranty or
Collateral; or (vi) changes this clause (b) or any other matter specifically
requiring the consent of all Lenders under this Agreement.

         (c) Conflicts. Any conflict or ambiguity between the terms and
provisions of this Agreement and terms and provisions in any other Credit
Document is controlled by the terms and provisions of this Agreement.

         (d) Waivers. No course of dealing or any failure or delay by
Administrative Agent, any Lender, or any of their respective Representatives
with respect to exercising any Right of Administrative Agent or any Lender under
this Agreement operates as a waiver thereof. A waiver must be in writing and
signed by Administrative Agent and Lenders (or Required Lenders, if permitted
under this Agreement) to be effective, and a waiver will be effective only in
the specific instance and for the specific purpose for which it is given.

         14.11 Multiple Counterparts. Any Credit Document may be executed in a
number of identical counterparts, and by each party thereto on separate
counterparts (including, at Administrative Agent's discretion, counterparts or
signature pages executed and transmitted by fax) with the same effect as if all
signatories had signed the same document. All counterparts must be construed
together to constitute one and the same instrument.

         14.12 Parties; Participations; Assignments.


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 71               ULTRAK OPERATING, L.P.

<PAGE>   78






         (a) Parties Bound. Each Credit Document binds and inures to the parties
to it, any intended beneficiary of it, and each of their respective successors
and permitted assigns. No Company may assign or transfer any Rights or
obligations under any Credit Document without first obtaining all Lenders'
consent, and any purported assignment or transfer without such consent is void.

         (b) Participations. Any Lender may (subject to the provisions of this
section, in accordance with applicable Laws, in the ordinary course of its
business, and at any time) sell to one or more Persons (each a "PARTICIPANT")
participating interests in its portion of the Obligation. The selling Lender
remains a "Lender" under the Credit Documents, the Participant does not become a
"Lender" under the Credit Documents, and the selling Lender's obligations under
the Credit Documents remain unchanged. The selling Lender remains solely
responsible for the performance of its obligations and remains the holder of its
share of the Principal Debt for all purposes under the Credit Documents.
Borrower and Administrative Agent shall continue to deal solely and directly
with the selling Lender in connection with that Lender's Rights and obligations
under the Credit Documents, and each Lender must retain the sole right and
responsibility to enforce due obligations of the Companies. Participants have no
Rights under the Credit Documents except certain voting rights as provided
below. Subject to the following, each Lender may obtain (on behalf of its
Participants) the benefits of Section 3 with respect to all participations in
its part of the Obligation outstanding from time to time so long as Borrower is
not obligated to pay any amount in excess of the amount that would be due to
that Lender under Section 3 calculated as though no participations have been
made. No Lender may sell any participating interest under which the Participant
has any Rights to approve any amendment, modification, or waiver of any Credit
Document except as to matters in Section 14.10(b)(i) and (ii).

         (c) Assignments. Each Lender may make assignments to the Federal
Reserve Bank. Each Lender may also assign to one or more assignees (each an
"ASSIGNEE") all or any part of its Rights and obligations under the Credit
Documents so long as (i) the assignor Lender and Assignee execute and deliver to
Administrative Agent for its consent and acceptance (that may not be
unreasonably withheld in any instance and is not required if the Assignee is an
Affiliate of the assigning Lender) an assignment and assumption agreement in
substantially the form of Exhibit J (a "NOTE AND LIEN ASSIGNMENT") and pays to
Administrative Agent a processing fee of Two Thousand Five Hundred Dollars
($2,500), (ii) the assignment must be for a minimum total Commitment of Five
Million Dollars ($5,000,000) and, if the assigning Lender retains any
Commitment, it must be a minimum total Commitment of Five Million Dollars
($5,000,000), and (iii) the conditions for that assignment set forth in the
applicable Note and Lien Assignment are satisfied. The "Effective Date" in each
Note and Lien Assignment must (unless a shorter period is agreeable to Borrower
and Administrative Agent) be at least five Business Days after it is executed
and delivered by the assignor Lender and the Assignee to Administrative Agent
for acceptance. Once that Note and Lien Assignment is accepted by Administrative
Agent, and subject to all of the following occurring, then, on and after the
"Effective Date" stated in it (i) the Assignee automatically becomes a party to
this Agreement and, to the extent provided in that Note and Lien Assignment, has
the Rights and obligations of a Lender under the Credit Documents, (ii) the
assignor Lender, to the extent provided in that Note and Lien Assignment, is
released from its obligations to fund Borrowings under this Agreement and its
reimbursement obligations under this Agreement and, in the case of a Note and
Lien Assignment covering all of the remaining portion of the assignor Lender's
Rights and obligations under the Credit Documents, that Lender ceases to be a
party to the Credit Documents, (iii) Borrower shall execute and deliver to the
assignor Lender and the Assignee the appropriate Notes in accordance with this
Agreement following the transfer, (iv) upon delivery of the Notes under clause
(iii) preceding, the assignor Lender shall return to Borrower all Notes
previously delivered to that Lender under this Agreement, and (v) Schedule 2 is
automatically deemed to be amended to reflect the name, address, telecopy
number, and Commitment of the Assignee and the remaining Commitment (if any) of
the assignor


                                           AMENDED AND RESTATED CREDIT AGREEMENT
AMERICAN NATIONAL BANK              Page 72               ULTRAK OPERATING, L.P.

<PAGE>   79




Lender, and Administrative Agent shall prepare and circulate to Borrower and
Lenders an amended Schedule 2 reflecting those changes. By executing and
delivering a Note and Lien Assignment, the Lender assignor thereunder and the
assignee thereunder confirm to and agree with each other and the other parties
hereto as follows: (i) other than as provided in such Note and Lien Assignment,
such assigning Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with the Loan Documents or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of any Loan Document
or any other instrument or document furnished pursuant hereto; (ii) such
assigning Lender makes no representation or warranty and assumes no
responsibility with respect to the financial condition of Borrower or the
performance or observance by any of any Company of any of its obligations under
any Loan Document or any other instrument or document furnished pursuant hereto;
(iii) such assignee confirms that it has received a copy of this Agreement,
together with copies of the financial statements referred to in Section 5.1 and
such other documents and information as it has deemed appropriate to make its
own credit analysis and decision to enter into such Note and Lien Assignment;
(iv) such assignee will, independently and without reliance upon Administrative
Lender, such assigning Lender or any other Lender and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit decisions in taking or not taking action under the Loan Documents;
(v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee
appoints and authorizes Administrative Lender to take such action as agent on
its behalf and to exercise such powers under the Loan Documents as are delegated
to Administrative Lender by the terms thereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will
perform in accordance with their terms all of the obligations which by the terms
of this Agreement are required to be performed by it as a Lender.

         14.13 Venue, Service of Process, and Jury Trial. BORROWER AND (PURSUANT
TO ITS GUARANTY OR ITS EXECUTION AND DELIVERY OF, OR CONSENT TO, ANY OTHER
CREDIT DOCUMENT) EACH COMPANY, IN EACH CASE FOR ITSELF AND ITS SUCCESSORS AND
ASSIGNS, IRREVOCABLY (A) SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE
AND FEDERAL COURTS IN ILLINOIS, (B) WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAWS, ANY OBJECTION THAT IT MAY NOW OR IN THE FUTURE HAVE TO THE
LAYING OF VENUE OF ANY LITIGATION ARISING OUT OF OR IN CONNECTION WITH ANY
CREDIT DOCUMENT AND THE OBLIGATION BROUGHT IN THE FEDERAL OR STATE COURTS IN
CHICAGO, COOK COUNTY, ILLINOIS, (C) WAIVES ANY CLAIMS THAT ANY LITIGATION
BROUGHT IN ANY OF THE FOREGOING COURTS HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM, (D) CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THOSE COURTS IN ANY
LITIGATION BY THE MAILING OF COPIES OF THAT PROCESS BY CERTIFIED MAIL, RETURN
RECEIPT REQUESTED, POSTAGE PREPAID, BY HAND DELIVERY, OR BY DELIVERY BY A
NATIONALLY RECOGNIZED COURIER SERVICE, AND SERVICE SHALL BE DEEMED COMPLETE UPON
DELIVERY OF THE LEGAL PROCESS AT ITS ADDRESS FOR PURPOSES OF THIS AGREEMENT, (E)
AGREES THAT ANY LEGAL PROCEEDING AGAINST ANY PARTY TO ANY CREDIT DOCUMENT
ARISING OUT OF OR IN CONNECTION WITH THE CREDIT DOCUMENTS OR THE OBLIGATION MAY
BE BROUGHT IN ONE OF THE FOREGOING COURTS, AND (F) WAIVES TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAWS, ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM
OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY CREDIT DOCUMENT. The scope
of each of the foregoing waivers is intended to be all encompassing of any and
all disputes that may be filed in any court and that relate to the subject
matter of this transaction, including contract claims, tort claims, breach of
duty claims, and all other common law and statutory claims. BORROWER AND
(PURSUANT TO ITS GUARANTY OR ITS EXECUTION AND DELIVERY OF, OR CONSENT TO, ANY
OTHER CREDIT DOCUMENT) EACH OTHER COMPANY ACKNOWLEDGES THAT THESE WAIVERS ARE A
MATERIAL INDUCEMENT TO ADMINISTRATIVE AGENT'S AND EACH LENDER'S AGREEMENT TO
ENTER INTO A BUSINESS RELATIONSHIP, THAT ADMINISTRATIVE AGENT AND EACH LENDER
HAS ALREADY RELIED ON THESE WAIVERS IN ENTERING INTO THIS AGREEMENT, AND THAT
ADMINISTRATIVE

AGENT AND EACH LENDER WILL CONTINUE TO RELY ON EACH OF THESE WAIVERS IN RELATED
FUTURE DEALINGS. BORROWER AND (PURSUANT TO ITS GUARANTY OR ITS EXECUTION AND
DELIVERY OF, OR CONSENT TO, ANY OTHER CREDIT DOCUMENT) EACH OTHER COMPANY
FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THESE WAIVERS WITH ITS
LEGAL COUNSEL, AND THAT IT KNOWINGLY AND VOLUNTARILY AGREES TO EACH WAIVER
FOLLOWING CONSULTATION WITH LEGAL COUNSEL. The waivers in this section are
irrevocable, meaning that they may not be modified either orally or in writing,
and these waivers apply to any future renewals, extensions, amendments,
modifications, or replacements in respect of the applicable Credit Document. In
connection with any Litigation, this Agreement may be filed as a written consent
to a trial by the court.

         14.14 Arbitration of Disputes. In the event of a dispute, claim or
controversty arising out of or relating to this Agreement, or relating to any
claim or cause of action which may arise or be asserted under any federal,
state, local or foreign statutory, regulatory or common law, including, without
limitation, claims with respect to breach of contract, tort, obligation of good
faith and fair dealing and fiduciary duties, Administrative Agent, Lenders,
Parent, Borrower and each other Company (by execution of a Credit Document)
agree that upon the written demand of any party, whether made before or after
the institution of any legal proceedings, but prior to the rendering of any
judgment in that proceeding, all and all such disputes, claims and controversies
between them, whether individual, joint, or class in nature, arising from this
Agreement, any of the Credit Documents, or otherwise, shall be resolved by
binding arbitration pursuant to the Commercial Rules of the American Arbitration
Association ("AAA"). Any arbitration proceeding held pursuant to this
arbitration provision shall be conducted in Dallas, Texas, or at any other place
selected by mutual agreement of the parties. No act to take or dispose of any
collateral shall constitute a waiver of this arbitration agreement or be
prohibited by this arbitration agreement. This arbitration provision shall not
limit the right of either party during any dispute, claim or controversy to
seek, use, and employ ancillary, or preliminary rights and/or remedies, judicial
or otherwise, for the purposes of realizing upon, preserving, protecting,
foreclosing upon or proceeding under forcible entry and detainer for possession
of, any real or personal property, and any such action shall not be deemed an
election of remedies. Such remedies include, without limitation, obtaining
injunctive relief or a temporary restraining order, invoking a power of sale
under any deed of trust or mortgage, obtaining a writ of attachment or
imposition of a receivership, or exercising any rights relating to personal
property, including exercising the right of set-off, or taking or disposing of
such property with or without judicial process pursuant to the Uniform
Commercial Code. Any disputes, claims or controversies concerning the lawfulness
or reasonableness of an act, or exercise of any right or remedy concerning any
collateral, including any claim to rescind, reform or otherwise modify any
agreement relating to the collateral, shall also be arbitrated; provided,
however, that no arbitrator shall have the right or the power to enjoin or
restrain any act of either party. No punitive, exemplary or consequential
damages may ever be awarded by the arbitrator or anyone else, and each of the
parties hereby waives any and all rights to make, claim or recover any such
damages. Judgment upon any award rendered by any arbitrator may be entered in
any court having jurisdiction. The statute of limitations, estoppel, waiver,
laches and similar doctrines which would otherwise be applicable in an action
brought by a party shall be applicable in any arbitration proceeding, and the
commencement of an arbitration proceeding shall be deemed the commencement of
any action for these purposes. The Federal Arbitration Act (Title 9 of the
United States Code) shall apply to the construction, interpretation and
enforcement of this arbitration provision.

         14.15 Restatement of Existing Agreement. The parties to this Agreement
agree that, at the Closing Time, after all conditions precedent set forth in
Section 6.1 have been satisfied or waived: (a) the Obligations represents, among
other things, the renewal, amendment, extension, consolidation and modification
of the "Obligation" (as defined in the Existing Agreement); (b) this Agreement
is intended to, and does hereby, restate, renew, extend, amend, modify,
consolidate, supersede and replace the Existing Agreement; (c) the Notes
executed pursuant to this Agreement amend, renew, extend, modify, replace,
consolidate, substitute for and supercede in their entirety (but do not
extinguish the Debt arising under) the promissory notes executed pursuant to the
Existing Agreement; and (d) the entering into and performance of their
respective obligations under this Agreement and the transactions contemplated by
the Credit Documents do not constitute a novation.

         14.16 Entirety. THE CREDIT DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN BORROWER, THE OTHER COMPANIES, LENDERS, AND ADMINISTRATIVE AGENT AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

         DULY EXECUTED AND DELIVERED by each of the signatories hereto as of the
date first stated in this Agreement.
