         2.       AMOUNT AND TERMS OF THE LOANS
                  -----------------------------

         2.01. Loan. The Bank agrees, on the terms and conditions set forth in
this Agreement, to make a term loan (the "Loan") to the Borrower on the date
hereof in the original principal amount of $7,500,000.

         2.02. Interest on the Loan. (a) The Borrower shall pay interest to the
Bank on the outstanding and unpaid principal amount of the Loan made under this
Agreement at a rate per annum equal to the Base Rate or the LIBOR Rate for such
Interest Period, as Borrower may choose. In the absence of Borrower's
designation, the Loan shall be made and maintained as a Base Rate Loan. Such
interest, calculated on the basis of a 360-day year for the actual number of
days elapsed, shall accrue daily in each Interest Period and shall be payable
quarterly in arrears on the first day of each January, April, July and October,
commencing July 1, 1997, and on the Maturity Date hereof (each an "Interest
Payment Date"), to the Bank. Interest shall be paid in such manner as the
Borrower and the Bank shall agree. The Borrower may elect from time to time to
convert the Loan from a LIBOR Loan to a Base Rate Loan and vice versa by giving
the Bank notice of the proposed conversion before the beginning of the proposed
Interest Period.

         2.03. Term Loan Conversion to IRB. Borrower intends to, and shall use
best efforts to, convert the Loan to a tax exempt Industrial Revenue Bond
("IRB") pursuant to the terms of a Financing Agreement to be entered into by and
between Borrower, the Bank and Industrial Development Board of the City of
Huntsville. Borrower shall execute all documents required in connection with the
issuance of the IRB, which documents shall be in form reasonably satisfactory to
the Bank. The Loan will become immediately due and payable upon conversion of
the Note to the IRB, however the proceeds from the issuance of the IRB may be
used to pay the Loan.

         2.04. Note. The Loan made by the Bank under this Agreement shall be
evidenced by, and repaid with interest in accordance with a term loan note
delivered by the Borrower to the Bank, dated as of the date of this Agreement
(the "Note"), substantially in the form of Exhibit A attached hereto, as
amended, supplemented or modified.

         2.05. Maturity Date. The Loan shall mature and be repayable in full on
that date (the "Maturity Date") which is the earlier of (a) conversion of the
Loan to an IRB; (b) May 31, 2000 or (c) that date which is eighteen (18) months
from the date on which Bank makes written demand for repayment in full under
Section 2.08.

         2.06. Default Interest. At any time after the occurrence of an Event of
Default hereunder, the Bank may at its option begin to charge and accrue
interest on the unpaid principal balance of the Note, on any amounts outstanding
hereunder or thereunder and, to the extent permitted by law, on any overdue
interest thereon until paid in full, payable on demand, at a rate per annum (the
"Default Rate") equal to (a) during the then current Interest Period, the
interest rate per annum then in effect for the Loan plus 2.00% and (b)

                                        6

<PAGE>



from and after the end of the then current Interest Period for the Loan, the
Base Rate plus 1.50%.

         2.07.    Optional Prepayments.  (a) The Borrower may, at its option, 
prepay the Note in whole or in part, as follows:

                  (1) for a Base Rate Loan, on any Business Day, with unpaid
accrued interest to the date of such prepayment on the amount prepaid, provided
that each partial prepayment shall be in a principal amount of not less than
$100,000 or integral multiples of $5,000 in excess thereof.

                  (2) for a LIBOR Loan, on the last day of the applicable
Interest Period, in whole or in part (but if in part, in the principal amount of
$100,000 or integral multiples of $5,000 in excess thereof) at a prepayment
price equal to the principal amount so prepaid, together with unpaid accrued
interest to the date of prepayment.

                  If Borrower voluntarily elects to repay all or any portion of
principal of the Loan before the expiration of any LIBOR Interest Period, the
Borrower shall simultaneously pay to the Bank such amount as shall be sufficient
to compensate the Lender for any loss, cost or expense that the Bank reasonably
determines to be directly attributable to the prepayment, including costs,
losses and expenses incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by the Bank to make or maintain its investment
in the Loan at a LIBOR based fixed interest rate. The Bank shall provide the
Borrower with evidence of the calculation of any such loss, cost or expense.

                  The Borrower shall provide the Bank with notice of any
optional prepayment pursuant to this paragraph and the principal amount of the
Note to be redeemed, sent at least one (1) day before such prepayment date. On
each such prepayment date, payment of the prepaid principal having been made to
Bank as provided herein, the Note or the portion thereof prepaid shall become
due and payable on the prepayment date and interest shall cease to accrue
thereon from and after the prepayment date.

         2.08. Mandatory Prepayments. Not later than eighteen (18) months
following written demand by Bank, Borrower shall prepay such portion (even if
all) of the outstanding principal of the Loan, together with unpaid accrued
interest, as the Bank may specify in its sole discretion.

         2.09. Method of Payment. Each payment under this Agreement and under
the Note shall be due not later than 2:00 p.m. Philadelphia time on the date
when due and shall be made in lawful money of the United States to the Bank in
immediately available funds. The Borrower hereby authorizes the Bank, and the
Bank shall, debit the Account for the amount of each payment under this
Agreement and under the Note not later than 2:00 p.m. Philadelphia time on the
date such payment becomes due under this Agreement or the Note. The foregoing
rights of the Bank to debit the Account shall be in addition to, and not in

                                        7

<PAGE>



limitation of, any rights of set-off that the Bank may have under the Loan
Documents and any other rights and remedies of the Bank under the Loan Documents
or law and do not in any manner limit the provisions of Section 6.01. Whenever
any payment to be made under this Agreement or under the Note shall be stated to
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of the payment of interest.

         2.10. Illegality. Notwithstanding any other provision in this
Agreement, if the adoption of any applicable law, rule, or regulation, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank, or comparable agency charged with the
interpretation or administration thereof, or compliance by the Bank with any
request or directive (whether or not having the force of law) of any such
authority, central bank, or comparable agency shall make it unlawful or
impossible for the Bank to make or maintain any LIBOR Loan, then upon notice to
the Borrower by the Bank the LIBOR Loan shall be converted to a Base Rate Loan
either (1) immediately upon demand of the Bank if such change or compliance with
such request, in the reasonable judgment of the Bank, requires immediate
conversion; or (2) upon the earlier of (i) the expiration of the Interest Period
for such LIBOR Loan and (ii) the effective date of any such change or request.

         2.11.    Disaster.  Notwithstanding anything to the contrary herein, if
the Bankm determines (which determination shall be conclusive) that:

                  (1) quotations of interest rates for the relevant deposits
referred to in the definition of LIBOR Rate are not being provided in the
relevant amounts or for the relative maturities for purposes of determining the
rate of interest on a LIBOR Loan as provided in this Agreement; or

                  (2) the relevant rates of interest referred to in the
definition of LIBOR Rate upon the basis of which the rate of interest, for such
type of Loan is to be determined do not accurately cover the cost to the Bank of
making or maintaining such type of Loan,

then the Bank shall give notice thereof to the Borrower whereupon until the Bank
notifies the Borrower that the circumstances giving rise to such suspension no
longer exist, (a) the obligation of the Bank to maintain a LIBOR Loan shall be
suspended immediately or, if the Loan is then outstanding as a LIBOR Loan, from
the last day of the Interest Period for such LIBOR Loan; and (b) if the Loan is
then outstanding as a LIBOR Loan, the Borrower shall convert such LIBOR Loan to
a Base Rate Loan on the last day of the Interest Period for such LIBOR Loan.

         2.12. Increased Cost. The Borrower shall pay to the Bank from time to
time such amounts as the Bank may determine to be necessary to compensate the
Bank for any costs incurred by the Bank which the Bank determines are
attributable to its making or maintaining the Loan as a LIBOR Loan hereunder or
its obligation to make or maintain the Loan as a

                                        8

<PAGE>



LIBOR Loan hereunder, or any reduction in any amount receivable by the Bank
under this Agreement or the Note in respect of any such Loan or such obligation
(such increases in costs and reductions in amounts receivable being herein
called "Additional Costs"), resulting from any change after the date of this
Agreement in United States federal, state, municipal, or foreign laws or
regulations (including Regulation D) or the adoption or making after such date
of any interpretations, directives or requirements applying to a class of banks
including the Bank of or under any United States federal, state, municipal, or
any foreign laws or regulations (whether or not having the force of law) by any
court or governmental or monetary authority charged with the interpretation or
administration thereof ("Regulatory Change"), which: (a) changes the basis of
taxation of any amounts payable to the Bank under this Agreement or the Note in
respect of any of such Loan (other than taxes imposed on the overall net income
of the Bank or its partners for any of such Loans by the jurisdiction where the
Bank is located); or (b) imposes or modifies any reserve, special deposit, or
similar requirements relating to any extensions of credit or other assets of, or
any deposits with or other liabilities of, the Bank; or (c) imposes any other
condition affecting this Agreement or the Note (or any of such extensions of
credit or liabilities).

         2.13.    Bank's Determinations Conclusive; Notice of Amounts Due.
                  --------------------------------------------------------

                  (1) Determination by the Bank of Additional Costs pursuant to
Section 2.12 shall be conclusive absent manifest error.

                  (2) The Bank will notify the Borrower of any event occurring
after the date of this Agreement that will entitle the Bank to compensation
pursuant to Section 2.12 as promptly as practicable after it obtains knowledge
thereof and determines to request such compensation. Said notice shall be in
writing and shall specify the applicable Section or Sections of this Agreement
to which it relates and shall set forth the amount or amounts then payable
pursuant to Section 2.12 and the Bank's calculation of such amount or amounts.
The Borrower shall pay the Bank the amount shown as due on any such notice
within 10 days after its receipt of the same.

                  (3) Failure on the part of the Bank to demand compensation for
Additional Costs with respect to any period pursuant to Section 2.12 shall not
constitute a waiver of the Bank's right to demand compensation with respect to
such period or any other period.

         3.       CONDITIONS TO LENDING.
                  ----------------------

         4.12. Information. All information heretofore furnished by the Obligors
to the Bank orally or in writing for purposes of or in connection with the Loan
Documents or the borrowing contemplated thereby is true and accurate in every
material respect or based upon reasonable estimates on the date as of which such

diligently conducted and for which adequate reserves have been established;

                  (h) easements, rights-of-way, restrictions, and other similar

Bank under the Security Agreement and the Mortgage.

                  5.10. Indebtedness. The Obligors will not, and will not cause
any of their Subsidiaries to, incur, create or permit to exist any indebtedness
without the prior written consent of the Bank, except that the Borrower may
incur, create or permit to exist the following:

                  (a) existing indebtedness disclosed in the Company's Form 10-Q
for the period ended January 31, 1997, or listed and described on Schedule 5.10
attached hereto and renewals, extensions and refinancings thereof, provided that
the effective rate of amortization thereof is not increased by any such renewal,
extension or refinancing and any such renewal extension or refinancing shall not
be on terms less favorable to the Obligors and their Subsidiaries than those
provided in the existing agreements for such indebtedness;

                  (b) indebtedness to the Bank;

                  (c) indebtedness subordinated to the indebtedness evidenced by

<PAGE>



compliance with the covenants contained in this Agreement and neither the

such indebtedness) in incurring such indebtedness;

conditions set forth in the proposed Commitment from CoreStates Bank, N.A. dated

continue to be acceptable so long as they are not changed in a way that is
materially adverse to the Obligors and their Subsidiaries.

         5.11. Guarantees. The Obligors will not, and will not cause any of
their Subsidiaries to, guarantee or otherwise become liable or responsible for

10-Q for the period ended January 31, 1997 or listed and described on Schedule

the normal course of business;

                  (c) guarantees issued in favor of the Bank;

                  (d) guarantees executed and delivered in connection with
unsecured lines of credit or unsecured revolving lines of credit permitted under
Section 5.10(g), provided that the amount of the indebtedness guaranteed shall
not exceed $55,000,000 in the aggregate for Obligors and their Subsidiaries at
any time; and

relevant Obligor, or (2) the date on which an executive officer of any Obligor
otherwise became aware of such failure; or

                  (c) any representation or warranty made by any Obligor in this
Agreement or the other Loan Documents, or otherwise in writing in connection
with the Loan, shall prove to have been false, incorrect or misleading in any
material respect on the date when made; or

in full force and effect or the enforceability thereof shall be challenged or

law or statute alleging that such Person is insolvent or unable to pay its debts
as they mature; or

                  (f) the entry of any judgment against any Obligor or any of
their Subsidiaries in an amount exceeding $750,000 or the issuing of any

                  (g) any Obligor or any Subsidiary of any Obligor shall fail to
pay when due (after giving effect to any grace period applicable thereto), any

provided that upon the happening of an Event of Default specified in section

delivered to, or be in the possession of, or held by the Bank in any capacity
whatsoever, including the balance of the Account and all other accounts
maintained by the Borrower with the Bank from time to time. The Borrower

or all of the amounts due under the Note and this Agreement any and all monies,
credits, claims or deposit balances now or hereafter in the possession or
control of the Bank belonging to or owned by the Borrower. The rights of the
Bank under this Section 6.02 are in addition to all other rights and remedies
available to the Bank, including other rights of set-off that the Bank may have.

<PAGE>



the courts of Pennsylvania and of the courts of the United States sitting in
Pennsylvania in any litigation concerning this Agreement and the Loan Documents
and waive any objection based on venue or inconvenient forum. Service of the
summons and complaint and any other process may be served in any such suit,
action or proceeding by sailing or delivering a copy of the process to the
Borrower at its address specified in, or provided to the Bank pursuant to, this
Agreement and in accordance with Section 7.01. The Borrower agrees that a final
judgment in any such suit, action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other or
provided by law. The Borrower irrevocably waives the right to trial by jury in
any such suit, action or proceeding and the right to judgment for, and to
collect, damages in any such suit, action or proceeding other than for losses
and expenses actually incurred or paid.

         8.02. Entire Agreement. This Agreement and the other Loan Documents
executed and delivered pursuant hereto, constitute the entire agreement between
the parties relating to the subject matter hereof and the transactions
contemplated hereby.

         8.03. Fees, Costs and Expenses. The Borrower agrees to pay all
reasonable attorneys fees associated with the preparation in executable form of
the Loan Documents in form satisfactory to the Bank (excluding the preparation
of the IRB and related documents, and fees and expenses relating to the

reasonable out of pocket expenses including reasonable counsel fees and
expenses, incurred by the Bank in connection with any negotiation and further
documentation of the Loan Documents; (b) the preparation of the IRB and related
documents; (c) all reasonable out of pocket expenses, including reasonable
attorneys fees and expenses, incurred by the Bank in connection with the
preparation and recording of the Mortgage; (d) all reasonable out of pocket
expenses including reasonable counsel fees and expenses, incurred by the Bank in
connection with the administration of the Loan and in connection with any
amendments to or modifications from time to time of the Loan Documents; (e) all
costs of collection (including reasonable counsel fees) if default is made in
the payment of amounts due under the Note or under the Loan Documents; (f) all
recording and other taxes and all filing fees, if any, on any documents executed

all Alabama taxes imposed on Bank or its partners if the Loan and the
transactions contemplated hereby require the Bank to qualify to do business in
the State of Alabama and thereby subject the Bank or its partners to taxation by
the State of Alabama.

         8.04. Severability. In case any one or more of the provisions contained
in any Loan Document should be invalid, illegal or unenforceable in any respect,
the validity, legality and enforceability of the remaining provisions contained
herein and therein shall not in any way be affected or impaired thereby, and any
prohibition or unenforceability of any provision of such Loan Document in any
jurisdiction shall not render unenforceable such provisions in any other
jurisdiction.

                                       24

<PAGE>



         8.05. Survival. All covenants, agreements, representations and
warranties made herein and in the other Loan Documents and in any certificates
delivered pursuant hereto shall survive the making by the Bank of the Loan(s)
and the execution and delivery to the Bank of the Loan Documents and shall
continue in full force and effect for so long as any amount due under the Note
or any amount due hereunder is outstanding and unpaid.

         8.06. Binding Effect. This Agreement and the other Loan Documents shall
be binding upon and inure to the benefit of the Obligors and the Bank and their
respective successors and assigns, except that no Obligor may assign, transfer
or convey any of Documents or its rights thereunder without the prior written
consent of the Bank.

         8.07. Modification or Waiver. No modification or waiver of any
provision of this Agreement or any other Loan Document, nor consent to any
departure by any Obligor shall in any event be effective unless the same shall
be in writing, and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given.

         8.08. Cumulative Effect. Each and every right granted to the Bank
hereunder and under the other Loan Documents, or allowed it by law or equity,
shall be cumulative and may be exercised from time to time. No failure on the
part of the Bank to exercise, and no delay in exercising, any right shall
operate as a waiver thereof, nor shall any single or partial exercise by the
Bank of any right preclude any other or future exercise thereof or the exercise
of any other right.

         8.09. Counterparts.  This Agreement may be executed in one or more 
counterparts, all of which taken together shall constitute one and the same 
agreement.

15. Commitments and Contingent Liabilities:

Unusual Non-Recurring Omega(TM) Charge



The Company has become aware of installation problems in certain steel pipe
systems utilizing Omega(TM) sprinklers. The addition of stop-leak products or
the presence of excessive hydrocarbons has been found in certain circumstances
to impair the operation of such sprinklers. In order to assess the extent of the
problems, the Company has strongly recommended that a sampling of Omega(Tm)
sprinklers from each such installed system be returned to the Company for
testing. Based on the results of the tests, the Company will review each
situation with the building owner and develop an appropriate action plan, as
needed.

The Company did not install such sprinklers and installation of the sprinklers
is the responsibility of the building owner. However, the Company's primary
concern is to offer the finest possible fire protection to building owners while
working within its sales and warranty policy to maintain customer goodwill. In
the fourth quarter of 1996, the Company recorded an unusual non-recurring charge
in cost of sales of $3,750 ($2,362 net of tax or $.72 per share) for the
estimated costs to be incurred by the Company for this program. The Company will
continue to monitor the results of the tests and costs incurred.
