authorized by the Obligor (but not obligated) to, record on any schedules

amount from the day after the due date thereof to the date of actual payment
(after as well as before judgment) at a rate per annum computed on the basis of
the actual number of days elapsed on the basis of a year consisting of 360
days, equal to the Designated Rate plus 4% per annum ("DEFAULT RATE").

         SECTION 2.05.    PAYMENTS.

         (a)     PRINCIPAL AND INTEREST.  If not sooner paid, the outstanding
principal amount of the Loan shall be paid on the Termination Date.  Interest
on the Loan shall be payable monthly in arrears on each Interest Payment Date,
commencing on February 1, 1998.  All payments by the Obligor pursuant to this
Note, whether in respect of principal, interest, or otherwise, shall be made
without setoff, counterclaim or deduction in same day funds by the Obligor to
the Holder.  All such payments required to be made to the Holder shall be made

Loan Account or such other account as the Holder shall specify from time to
time by notice to the Obligor.  Funds received after that time shall be deemed
to have been received by the Holder on the next following Business Day.
Whenever any payment to be made shall otherwise be due on a day which is not a
Business Day, such payment shall be made on the next succeeding Business Day
and such extension of time shall be included in computing interest, if any, in
connection with such payment.

         (b)     MANDATORY PAYMENTS.  Upon the occurrence of any Prepayment
Event, the principal amount outstanding hereunder, together with all accrued
interest hereon and any accrued unpaid fees and all other liabilities of the
Obligor accrued hereunder and under the other Loan Documents, shall
automatically become due and payable, both as to principal and interest,
without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived by the Obligor, anything contained herein to the
contrary notwithstanding.

         (c)     VOLUNTARY PAYMENTS. The Obligor may from time to time, upon at
least three days' prior written notice to the Holder, voluntarily prepay the
Loan in whole or in part without premium or penalty; provided that any partial
prepayment shall be in an aggregate principal amount of at least $100,000 and
in integral multiples of $25,000 in excess thereof.  Any partial prepayment
shall be applied to the principal amount of this Note.  All prepayments of
principal shall include interest accrued to the date of prepayment on the
principal amount being prepaid.  If the Obligor prepays the Loan in whole or in
part, or if the maturity of the Loan is accelerated, the Obligor shall pay the
Holder, at the time of any such prepayment or acceleration, a prepayment
premium in an amount equal to (i) the product of 4% multiplied by the aggregate
principal amount of the prepayment of the Loan, for any prepayment made prior
to the first anniversary of the Closing Date and (ii) the product of 3%
multiplied by the aggregate principal amount of the prepayment of the Loan, for
any prepayment made thereafter.

         (d)     REVIVAL OF PAYMENTS.  To the extent that the Obligor makes a
payment or payments to the Holder, which payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to a trustee, receiver or any other party under
any bankruptcy act, state or federal law, common law or equitable cause, then,
to the extent of such payment received, the Obligations or part thereof
intended to be satisfied shall be





                                      -9-
   15
revived and shall continue in full force and effect, as if such payments had
not been received by the Holder.

         (e)     ADDITIONAL AMOUNTS.  If the implementation of or any change in
any law or regulation or in the interpretation by any court or administrative
or governmental authority charged with their administration shall either (i)
impose, modify or deem applicable any reserve, special deposit, capital
adequacy or similar requirement not existing on the date of this Note against
any assets held by, deposits with or for the account of, or loans or
commitments by, the Holder in connection with this Note or the Loan (including
a request or requirement which affects the manner in which the Holder allocates
capital resources to its commitments, including its obligations hereunder); or
(ii) impose on the Holder any other condition not existing on the date of this
Note regarding this Note or the Loan and the result of any event referred to in
clause (i) or (ii) above shall be to (A) increase the cost to the Holder of
making or maintaining the Loan (which increase in cost shall be the result of
the Holder's reasonable allocation of the aggregate of such costs increases
resulting from such events), or (B) reduce any amounts payable by the Obligor
hereunder, or (C) reduce the rate of return on the Holder's capital as a
consequence of its making and maintaining of the Loan to a level below that
which the Holder could have achieved but for such circumstances, then, upon
demand by the Holder, the Obligor shall pay to the Holder, from time to time as
specified by the Holder, additional amounts which shall be sufficient to
compensate the Holder on an after-tax basis for such increased cost or
reduction in payment or in rate of return.  If any such amount is not paid on
demand by the Holder, the Obligor shall pay the Holder interest at the interest
rate specified in SECTION 2.04 on each such amount from the date when payment
was due until paid in full.  Each demand by the Holder hereunder shall be
accompanied by a certificate setting forth in reasonable detail such increased
cost or reduction in payment or in rate of return as a result of any event
mentioned in clause (i) or (ii) above and shall, absent manifest error, be
conclusive.  In determining such amounts, the Holder may use any reasonable
average and attribution methods.

         (f)     TAXES ON PAYMENTS.  All payments made by the Obligor under
this Note shall be made free and clear of, and without deduction or withholding
for or on account of, any future income, stamp or other taxes, levies, imposts,
deductions, charges, or withholdings excluding taxes imposed on net income of
the Holder (all such non-excluded taxes, levies, imposts, deductions, charges
or withholdings being hereinafter called "TAXES").  If any Taxes are required
to be withheld from any amounts so payable to the Holder hereunder, the amounts
so payable to the Holder shall be increased to the extent necessary to yield to
the Holder (after payment of all Taxes) interest or any such other amounts
payable hereunder at the rates or in the amounts specified in this Note.
Whenever any Tax is paid by the Obligor, as promptly as possible thereafter,
the Obligor shall send to the Holder a certified copy of any original official
receipt received by the Obligor showing payment thereof.  If the Obligor fails
to pay any Taxes when due to the appropriate taxing authority, the Obligor
shall indemnify the Holder for any incremental taxes, interest or penalties
that may become payable by the Holder as a result of any such failure.

                                      -14-
   20

Subsidiaries in the operation thereof (including all operations and conditions
at or in the properties of the Obligor and its Subsidiaries), and the assets
owned, leased, held or operated by the Obligor and its Subsidiaries, comply in
all material respects with all applicable laws, rules, regulations, ordinances
and codes of every kind, including Environmental Laws; (b) the Obligor and its
Subsidiaries have obtained all permits under Environmental Laws necessary to
its operations other than such permits the absence of which could not,
individually or in the aggregate, have a Material Adverse Effect, and all such
permits are in good standing and the Obligor and its Subsidiaries are in
compliance with all material terms and conditions of such permits; and (c)
neither the Obligor nor its Subsidiaries have received (i) any claim or notice
of violation, lien, complaint, suit, order or other claim or notice to the
effect that it is or may be liable to any Person as a result of (A) the
environmental condition of any of their respective properties or any other
property, or (B) the release or threatened release of any Hazardous Materials,
or (ii) any letter or request for information under Section 104 of the
Comprehensive Environmental Response, Compensation and Liability Act of 1980,
as amended (42 U.S.C. Section 9604), or comparable state laws, and to the best
of the Obligor's knowledge, none of the operations of the Obligor or its
Subsidiaries are the subject of any federal or state investigation evaluating
whether any remedial action is needed to respond to a release or threatened
release of any Hazardous Material at the Obligor's or its Subsidiaries'
properties or at any other location, including any location to which the
Obligor or its Subsidiaries have transported, or arranged for the
transportation of, any Hazardous Materials.

         SECTION 4.11.    AGREEMENTS.  Neither the Obligor nor its Subsidiaries
are a party to any agreement or instrument or subject to any restriction that

its Subsidiaries are engaged principally, or as of one of their important
activities, in the business of extending credit for the purpose of purchasing
or carrying Margin Stock.  Neither the Loan nor any of the proceeds thereof,
are for the purpose, whether immediate, incidental or ultimate of (a) buying or
carrying Margin Stock, or (b) extending credit to others for the purpose of
buying or carrying Margin Stock, or (c) refunding indebtedness originally
incurred for such purpose, or for any purpose which entails a violation of, or
which is inconsistent with, the provisions of Regulations of the Board,

         SECTION 4.13.    TAXES.  The Obligor and each of its Subsidiaries have
filed or caused to be filed all Federal, state and local tax returns which are
required to be filed by it, and has paid or caused to be paid all taxes shown
to be due and payable on such returns or on any assessments received by it,
other than any taxes or assessments, the validity of which the Obligor is
contesting in good faith by appropriate proceedings, and with respect to which
the Obligor shall have set aside on its books adequate reserves.

         SECTION 4.14.    LABOR AND EMPLOYMENT.  The Obligor, each ERISA
Affiliate and each Plan is in compliance in all material respects with those
provisions of ERISA, the Internal





                                      -15-
   21
Revenue Code of 1986 and the Age Discrimination in Employment Act, and the
regulations and published interpretations thereunder which are applicable to
the Obligor, any ERISA Affiliate or such Plan. As of the date hereof, no
Reportable Event has occurred with respect to any Pension Plan as to which the
Obligor or any ERISA Affiliate was required to file a report with the Pension
Benefit Guaranty Corporation.  No Pension Plan (other than a Multiemployer
Plan) has any material amount of unfunded benefit liabilities (within the
meaning of Section 4001(a)(18) of ERISA) or any accumulated funding deficiency
(within the meaning of Section 302(a)(2) of ERISA), whether or  not waived, and
neither the Obligor nor any of its ERISA Affiliates has incurred or expects to
incur any material withdrawal liability under Subtitle E of Title IV of ERISA
to a Multiemployer Plan. No Plan of the Obligor or any ERISA Affiliate
obligates any of such Persons to provide post-retirement medical benefits,
except as may be required by the Consolidated Omnibus Budget Reconciliation Act
of 1985.  The Obligor and each ERISA Affiliate is in compliance in all material
respects with all labor and employment laws, rules, regulations and
requirements of all applicable domestic and foreign jurisdictions.  There are
no pending or threatened (in writing) labor disputes, work stoppages or
strikes.

         SECTION 4.15.    INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING
COMPANY ACT.  Neither the Obligor nor any of its Subsidiaries is (a) an
"investment company" as defined in, or subject to regulation under, the
Investment Company Act of 1940, or (b) a "holding company" as defined in, or
subject to regulation under, the Public Utility Holding Company Act of 1935.

         SECTION 4.16.    CAPITALIZATION.  After giving effect to the
Transactions and after the date hereof the record and beneficial (within the
meaning of applicable rules and regulations promulgated by the Securities and
Exchange Commission) owners of the equity interests of the Obligor (other than
non- Affiliate members of the general investing public) are correctly set forth
in SCHEDULE 4.16.  Except for Liens granted pursuant to the Related
Transactions, all such equity interests of Larry L. Asche, Diane L. Asche,
Kevin M. Clark, Leon M. Monachos and Gary I. Goldberg are owned free and clear
of all Liens, such Persons have the unencumbered right to vote all of such
interests and there are no outstanding options, warrants (other than the
Warrant) or rights to purchase, nor any agreement for the subscription,
purchase or acquisition of, any of such interests.

         SECTION 4.17.    PROPERTIES.  The Obligor has good and marketable
title to, or valid leasehold interests in, all of its material assets and
properties reflected in its most recent balance sheet, except for such
properties as are no longer useful in the conduct of its business or have been
disposed of in the ordinary course of business, subject to no liens except for
Permitted Liens.  All such assets and properties are in good repair, working
order and condition and all such assets and properties are owned by the Obligor
free and clear of all Liens other than Permitted Liens.

         SECTION 4.18.    INTELLECTUAL PROPERTY; LICENSES.  The Obligor
possesses adequate assets, licenses, patents, patent applications, copyrights,
trademarks, trademark applications and tradenames to continue to conduct its
business as heretofore conducted.  No event has occurred which permits, or
after notice or lapse of time or both would permit, the revocation or
termination of any of the foregoing which taken in isolation or when considered
with all other such revocations or terminations could have a Material Adverse
Effect.  The Obligor has no notice or knowledge of





                                      -16-
   22
any fact or any past, present or threatened occurrence that could preclude or
impair the Obligor's ability to retain or obtain any authorization necessary
for the operation of its businesses.

         SECTION 4.19.    SOLVENCY.  Neither the Obligor nor STS is insolvent
and the execution and delivery of this Note and the other Loan Documents
pursuant thereto and the consummation of the Transactions and the Related
Transactions will not render the Obligor or STS insolvent.  Each of the fair
value and present fair saleable value of the assets of the Obligor or STS
exceeds its respective liabilities.  The Obligor understands that in this
context "insolvent" means, with respect to any Person, that the present fair
saleable value of the total assets of such Person is less than the amount of
the total liabilities of such Person.  The Obligor also understands that the
term "liabilities" includes any legal liability, whether matured or unmatured,
liquidated or unliquidated, absolute, fixed or contingent (with contingent
liabilities valued based on the Obligor's good faith estimate of the
probability of occurrence).  Neither the Obligor nor STS will be unable to pay
its debts as they become absolute and mature.  Neither the Obligor nor STS will
incur debts beyond its ability to pay as they mature.  The borrowing of the
Loan and the consummation of the Transactions and the Related Transactions will
not leave the Obligor or STS with property remaining in its hands constituting
unreasonably small capital with which to conduct its business.

         SECTION 4.20.    COMPLETE DISCLOSURE.  All factual information
furnished by or on behalf of the Obligor to the Holder for purposes of or in
connection with this Note or the Transactions or Related Transactions is, and
all other such factual information hereafter furnished by or on behalf of the
Obligor will be, true and accurate in all material respects on the date as of
which such information is furnished and not incomplete by omitting to state any
fact necessary to make such information not misleading at such time in light of
the circumstances under which such information was provided.

                                   ARTICLE V
                             AFFIRMATIVE COVENANTS

needful and proper repairs, renewals, additions, improvements and replacements
thereto necessary in order that the business carried on in connection therewith
may be properly conducted at all times.

policies issued by financially sound and reputable insurers having general
policyholder ratings of at least AA in Best's Insurance Guide or any successor
thereto, in such amounts as are customary with companies similarly situated and
in the same or similar business.  The Obligor shall pay all insurance premiums
payable by it and, at the Holder's request, shall deliver copies of
certificates of insurance (with copies of such policies) to the Holder.  In
case of any material loss, damage to or destruction of a substantial portion of
any material property of the Obligor, the Obligor shall promptly give written
notice thereof to the Holder generally describing the nature and extent of such
damage or destruction, and the Obligor, whether or not the insurance proceeds,
if any, received on account of such damage or destruction shall be sufficient
for that purpose, at the Obligor's sole cost and expense, will promptly repair
or replace the property so lost, damaged or destroyed.

premiums payable by it in respect thereof and, within twenty (20) Business Day
after the Closing Date, shall deliver the policy of such insurance (or
certificate of insurance with a copy of such policy) to the Holder.  Such
insurance policy shall contain an assignment or pledge, as the case may be, of
Obligor's beneficial interest in such policy to the Holder, in form and
substance reasonably satisfactory to the Holder, providing that such insurance
shall not be cancelable except upon 30 days' prior notice to the Holder.

when due all taxes, assessments and governmental charges or levies imposed upon

liens or charges upon such properties or any part thereof; provided, however,
that the Obligor shall not be required to pay and discharge or to cause to be
paid and discharged any such tax, assessment, charge, levy or claim so long as
the validity or amount thereof shall be contested in good faith by appropriate
proceedings and the Obligor shall have set aside on its books adequate reserves
with respect thereto.

         SECTION 5.05.    FINANCIAL STATEMENTS; REPORTS.  Furnish to the

         (b)     The Obligor agrees to indemnify the Holder and its Affiliates,

claims, damages, liabilities, penalties, actions, judgments, suits, costs, and

Indemnified Person





                                      -28-

solely from the gross negligence or willful misconduct of such Indemnified
Person.

         (c)     The provisions of this Section shall remain operative and in
full force and effect regardless of the expiration of the term of this Note or

this Note or any of the other Loan Documents, or any investigation made by or

special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by the Holder to or for the credit or the
account of the Obligor to amounts then due and payable under this Note and the
other Loan Documents, irrespective of whether or not the Holder shall have made

exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power.  The rights and remedies of the Holder hereunder are cumulative
and not exclusive of any rights or remedies which it would otherwise have.  No
waiver of any provision of this Note or the other Loan Documents, or consent to
any departure by the Obligor therefrom shall in any event be effective unless
the same shall be authorized as provided in SECTION 9.08, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given.  No notice or demand on the Obligor in any case shall entitle
the Obligor to any other or further notice or demand in similar or other

not in any way be affected or impaired thereby.

more counterparts, each of which shall constitute an original, but all of which

each of the parties hereto shall be delivered or mailed to the Holder and the
Obligor.

BEFORE A JURY.  THE TERMS AND PROVISIONS OF THIS SECTION CONSTITUTE A MATERIAL
INDUCEMENT FOR THE PARTIES ENTERING INTO THIS NOTE.

         SECTION 9.14.    INTEREST LIMITATION.  Anything in this Note or any
Loan Document to the contrary notwithstanding, the Obligor shall never be
required to pay interest at a rate in excess of the highest lawful rate, and if
the effective rate of interest that would otherwise be payable under this Note
or any Loan Document would exceed the highest lawful rate, or if any holder of
this Note shall receive monies that are deemed to constitute interest which
would increase the effective rate of interest payable under this Note or any
Loan Document to a rate in excess of the highest lawful rate, then (a) the
amount of interest that would otherwise be payable under this Note and the Loan
Documents shall be reduced to the amount allowed under applicable law, and (b)
any interest paid





                                      -30-

inconsistency between the terms and provisions of this Note and those of any
other Loan Document, the terms and provisions of this Note shall govern and
control to the extent of such conflict or inconsistency.
