Outstandings to CIH, and the aggregate of all of the Banks' CIH Revolving Credit

obligation to make Revolving Credit Loans hereunder on or after the Expiration

separately with respect to the Term Loan Commitments, and CIH with respect to
the CIH Revolving Credit 


                                      -31-

Commitments, shall have the right at any time and from time to time upon not
less than three (3) Business Days' prior written notice to the Agent at the
Applicable Lending Office to permanently reduce, in a minimum amount of
$5,000,000 (or the Dollar Equivalent in the case of CIH) and in integral
multiples of $1,000,000 (or the Dollar Equivalent in the case of CIH), or
terminate their respective Commitments, both without penalty or premium, except
as hereinafter set forth, provided that any such reduction or termination shall
be accompanied by (a) the payment in full by the Borrower so reducing its
applicable Commitment of any applicable Commitment Fee then accrued on the
amount of such reduction or termination and (b) prepayment of the Revolving
Credit Notes and/or Term Notes of such Borrower in an amount equal to the amount
by which the then outstanding balance of (i) Revolving Credit Loans plus Bid
Loans plus Letter of Credit Outstandings to such Borrower exceeds the Revolving
Credit Commitments to such Borrower or (ii) the Term Notes exceeds the Term Loan
Commitments, in either case after such reduction or termination, as applicable,
together with the full amount of interest accrued on the principal sum to be
prepaid (and all amounts referred to in Section 5.6). From the effective date of
any such reduction or termination, the obligations of TEC or CIH, as the case
may be, to pay the relevant Commitment Fee pursuant to Section 2.3 shall
correspondingly be reduced or cease.

                  2.4.2 COLLATERAL FOR LETTER OF CREDIT/GUARANTEE OUTSTANDINGS
TO TEC.

            In the case of a voluntary reduction by TEC or the termination for
any reason of the TEC Revolving Credit Commitments, TEC shall deposit in a
non-interest bearing blocked cash collateral account with the Agent (provided
that (i) with the consent of the Agent, such account shall bear interest and
(ii) the Agent shall utilize good faith efforts to grant such consent), as cash
collateral for its Obligations in respect of the Letters of Credit and related
applications and agreements, the amount, if any, by which the resulting TEC
Revolving Credit Usage exceeds the TEC Revolving Credit Commitments as so
reduced or terminated, and TEC hereby pledges to the Agent and the Banks, and
grants to the Agent and the Banks a security interest in, all such cash as
security for such Obligations. From time to time the Agent shall return to TEC
any excess of the amount held in such account over the amount by which the TEC
Revolving Credit Usage then exceeds the TEC Revolving Credit Commitments. For
the purposes of this Section 2.4.2, the phrase "TEC Revolving Credit Usage"
shall mean, at any time, the sum of the TEC Revolving Credit Loans and TEC Bid
Loans outstanding plus the Letters of Credit/Guarantee Outstandings to TEC.

                  2.4.3 COLLATERAL FOR BANK GUARANTEE OUTSTANDINGS.

            In the case of a voluntary reduction by CIH or the termination, for
any reason, of the CIH Revolving Credit Commitments, CIH shall deposit in a
non-interest bearing blocked cash collateral account with the Agent (provided
that (i) with the consent of the Agent, such account shall bear interest and
(ii) the Agent shall utilize good faith efforts to grant such consent) or as the
Agent may direct, as cash collateral for its Obligations in respect of the Bank
Guarantees and related applications and agreements, the amount, if any, by which
the resulting CIH Revolving Credit Usage exceeds the CIH Revolving Credit
Commitments as so reduced or 


                                      -32-
<PAGE>   42

terminated, and CIH hereby pledges to the Agent and the Banks, and grants to the
Agent and the Banks a security interest in, all such cash as security for such
Obligations and agrees to grant to the Agent such further security over such
cash as it may require from time to time. From time to time the Agent shall
return to CIH any excess of the amount held in such account over the amount by
which the CIH Revolving Credit Usage then exceeds the CIH Revolving Credit
Commitments. For the purposes of this Section 2.4.3, the phrase "CIH Revolving
Credit Usage" shall mean, at any time, the sum of the CIH Revolving Credit Loans
and CIH Bid Loans outstanding plus the Letters of Credit/Guarantee Outstandings
to CIH.

            2.5 REVOLVING CREDIT LOAN REQUESTS.

            Except as otherwise provided herein, TEC may from time to time prior
to the Expiration Date request the Banks to make Revolving Credit Loans to it,

Revolving Credit Loans pursuant to Section 4.1.1, by delivering to the Agent, at
its Principal Office, not later than 12:00 p.m., Pittsburgh, Pennsylvania time,
(i) three (3) Business Days prior to the proposed Borrowing Date with respect to
the making of TEC Revolving Credit Loans to which the Revolving Credit Euro-Rate

Euro-Rate Option for any Revolving Credit Loans; and (ii) not later than 12:00
p.m., Pittsburgh, Pennsylvania time on the proposed Borrowing Date with respect
to the making of a Revolving Credit Loan to which the Revolving Credit Base Rate
Option applies or the last day of the preceding Interest Period with respect to
the conversion to the Revolving Credit Base Rate Option for any Revolving Credit
Loan, of a duly completed request therefor substantially in the form of EXHIBIT
2.5(A) or a request by telephone immediately confirmed in writing by letter,
facsimile or telex in such form (each, a "Revolving Credit Loan Request"), it
being understood that the Agent may rely on the authority of any individual
making such a telephonic request without the necessity of receipt of such
written confirmation. Each Loan Request shall be irrevocable and shall specify
the following information and such other information as is set forth on EXHIBIT
2.5(A): (i) the proposed Borrowing Date; (ii) the aggregate amount of the
proposed Revolving Credit Loans comprising each Borrowing Tranche, which shall
be in integral multiples of $1,000,000 and not less than $5,000,000 for each
Borrowing Tranche to which the Revolving Credit Euro-Rate Option applies and not
less than the lesser of $1,000,000 (or the Dollar Equivalent) or the maximum

Option applies; (iii) whether the Revolving Credit Euro-Rate Option or Revolving
Credit Base Rate Option shall apply to the proposed Revolving Credit Loans
comprising the applicable Borrowing Tranche; and (iv) in the case of a Borrowing

Interest Period for the proposed Revolving Credit Loans comprising such
Borrowing Tranche. CIH shall be entitled to make Drawings of the CIH Revolving
Credit Loan or renew or convert the Interest Rate Option applicable to its then
existing Revolving Credit Loans pursuant to Section 4.1.1 as set out above in
relation to TEC but substituting, as applicable, the Agent's London Office,
11:00 a.m. London time, Exhibit 2.5(B), a requirement that requests for

            2.6 MAKING REVOLVING CREDIT LOANS.

            The Agent shall, promptly after receipt by it of a Loan Request
pursuant to Section 2.5, notify the Banks of its receipt of the related Loan
Request specifying: (i) the proposed Borrower and Borrowing Date of such
Revolving Credit Loans; (ii) the amount and type of each such Revolving Credit
Loan and the applicable Interest Period (if any); and (iii) the apportionment
among the Banks of such Revolving Credit Loans as determined by the Agent in
accordance with Section 2.2. In addition, after the applicable interest rate is
determined, the Agent will promptly notify the Banks and each of the Borrowers
of the interest rate. After the Syndication Date, if the Loan Request is for a
CIH Revolving Credit Loan subject to the UK Euro-Rate Option for an Interest
Period of less than one Month, each co-agnet shall notify the Agent of its cost
of funds quote by the required time as contemplated in clause (B) of the
definition of UK Euro-Rate. Each Bank shall remit the principal amount of each
Revolving Credit Loan to the Agent (to such account as the Agent may nominate in
writing from time to time) such that the Agent is able to, and the Agent shall,
to the extent the Banks have made funds available to it for such purpose, fund
such Revolving Credit Loans to the requesting Borrower in Dollars or (as
applicable) Pounds Sterling at the Applicable Lending Office prior to (as
applicable) 2:00 p.m. Pittsburgh time or 1:00 p.m. London time in immediately
available funds on the applicable Borrowing Date, PROVIDED that if the Agent
assumes pursuant to Section 10.16 that a Bank will make available to the Agent
such Bank's portion of a Revolving Credit Loan and such Bank fails to remit such
funds to the Agent in a timely manner, the Agent may elect in its sole
discretion to fund with its own funds the Revolving Credit Loans of such Bank on
such Borrowing Date, and such Bank shall be subject to the repayment obligation
in Section 10.16.

            2.7 REVOLVING CREDIT NOTES.

            The Obligation of a Borrower to repay the aggregate unpaid principal
amount of the Revolving Credit Loans made to it by each Bank, together with
interest thereon, shall be evidenced by an appropriate Revolving Credit Note in
the form of EXHIBIT 1.1(R)(1) OR (2) payable to the order of such Bank in a face
amount equal to the Revolving Credit Commitment of such Bank to such Borrower.

            2.8 USE OF REVOLVING CREDIT PROCEEDS.

            The proceeds of the TEC Revolving Credit Loans shall be used for
general corporate purposes. The proceeds of the CIH Revolving Credit Loans shall
be used as follows: (i) to finance the acquisition by CIH of Ultra in an amount
not to exceed the lesser of $44,000,000 or the Dollar Equivalent of
(pound)26,000,000, in either case, minus the amount of financing of the purchase
price provided by the seller (the "Seller Loan"); (ii) if a Seller Loan is
obtained, to repay the Seller Loan; and (iii) the balance (not to exceed
$10,000,000 or its Dollar Equivalent), if any, for general corporate purposes.

            2.9 LETTERS OF CREDIT SUBFACILITY FOR TEC.

                  2.9.1 ISSUANCE OF LETTERS OF CREDIT FOR TEC'S ACCOUNT.

                  TEC may request the issuance of (or modification of any
issued) letters of credit (each a "Letter of Credit" and in the aggregate the
"Letters of Credit") on behalf of itself for its general corporate purposes by
delivering no later than 12:00 p.m., Pittsburgh, Pennsylvania time three (3)
Business Days prior to the requested date of issuance of such Letter of Credit
to the Agent a written notice specifying the proposed beneficiary, date of
issuance and expiry date for such Letter of Credit or modification to an
existing Letter of Credit and the nature of the transactions to be supported
thereby. Subject to the terms and conditions hereof and to the execution of a
completed application and continuing agreement for letters of credit in the form
attached hereto as EXHIBIT 2.9.1 or such other form as the Agent may specify
from time to time and in reliance on the agreements of the Banks set forth in
this Section 2.9, the Agent will issue a Letter of Credit provided that each
Letter of Credit shall (A) have a maximum maturity of 365 days from and
including the date of issuance, (B) in no event expire later than five Business
Days prior to the Expiration Date and provided further that in no event shall
(i) the Letter of Credit/Guarantee Outstandings to TEC exceed, at any one time,
$20,000,000 or (ii) the sum of the TEC Revolving Credit Loans plus TEC Bid Loans
plus Letter of Credit/Guarantee Outstandings to TEC then outstanding exceed, at
any one time, the TEC Revolving Credit Commitments. In the event of any conflict
between the terms of this Agreement and the terms of the forms of application
and agreement for letters of credit, the terms of this Agreement shall control
(provided that terms of the Agent's form of application and continuing agreement
for letters of credit which are in addition to those contained herein and which
do not expressly conflict with the terms contained herein shall not be deemed to
be in conflict with this Agreement), provided, however, that notwithstanding the
foregoing, the provisions of the application and agreement for letters of
credit, to the extent the same pertain to remedies, shall govern and control.
Notwithstanding the minimum draw requirements for Revolving Credit Loans, any
standby Letter of Credit may be requested for an amount greater than or equal to
$250,000 and any Documentary Letter of Credit may be requested for an amount
greater than or equal to $50,000.

                  2.9.2 PARTICIPATIONS.

                  Immediately upon issuance of each Letter of Credit, and
without further action, each Bank shall be deemed to, and hereby agrees that it
shall have irrevocably purchased for such Bank's own account and risk from the
Agent an individual participation interest in such Letter of Credit and drawings
thereunder in an amount equal to such Bank's Revolving Credit Ratable Share of
the maximum amount which is or at any time may become available to be drawn
thereunder, and each Bank shall be responsible to reimburse the Agent
immediately for its Revolving Credit Ratable Share of any disbursement under any
Letter of Credit which has not been reimbursed by TEC in accordance with Section
2.9.4 by making its Revolving Credit Ratable Share of the Revolving Credit Loans
referred to in Section 2.9.4 available to the Agent. Upon the request of any
Bank and upon the issuance and the termination of each Letter of 


                                      -35-
<PAGE>   45

Credit, the Agent shall notify each Bank of the amount of such Bank's
participation in Letters of Credit.

                  2.9.3 LETTER OF CREDIT FEES.

                  TEC shall pay to the Agent for the ratable account of the
Banks as provided in Section 5.2.1 fees ("Letters of Credit Fees") with respect
to Letter of Credit/Guarantee Outstandings to TEC in respect of Letters of
Credit in an amount equal to such Letter of Credit/Guarantee Outstandings to TEC
multiplied by a rate per annum (computed on the basis of a year of 360 days and
actual days elapsed) as specified in the definition of Applicable Margin
separately for standby Letters of Credit and for Documentary Letters of Credit,
for the applicable period specified in such definition, payable quarterly in
arrears on the first Business Day of each January, April, July and October
following the Closing Date and on the earlier of the Expiration Date or the
acceleration of the Notes. Such rates (per annum) of the foregoing Letters of
Credit Fees shall change on the effective date of any change in the Applicable
Margin.

                  TEC shall also pay to the Agent for its sole account (i) a
fronting fee equal to one-eighth of one percent (0.125%) per annum of the
aggregate undrawn face amount of each Letter of Credit payable quarterly in
arrears, and (ii) its then in effect customary issuance fees and administrative
expense payable with respect to its Letters of Credit as the Agent may generally
charge or incur from time to time in connection with the issuance, maintenance,
modification (if any), assignment or transfer (if any), negotiation, and
administration of letters of credit, payable at such times as the Agent may
specify.

                  2.9.4 DISBURSEMENTS; REIMBURSEMENT.

                  TEC shall be obligated immediately to reimburse the Agent for
all amounts which the Agent is required to pay pursuant to the Letters of Credit
issued by the Agent on or before the date on which the Agent is required to make
payment with respect to a draft presented thereunder. The Agent will promptly
notify TEC of each demand or presentment for payment or draft accepted for
payment or other drawing under each Letter of Credit issued by the Agent. The
Agent shall promptly notify each Bank of the amount required to be paid by such
Bank as a result of a drawing upon such Letter of Credit if TEC has not timely
reimbursed the Agent for such draw. If such notice is received by a Bank before
1:00 p.m., Pittsburgh, Pennsylvania time, such Bank shall deliver such Bank's
Revolving Credit Ratable Share of such payment in immediately available funds to
the Agent on that Business Day. If such notice is received by a Bank after 1:00
p.m., Pittsburgh, Pennsylvania time, such Bank shall before 10:00 a.m.,
Pittsburgh, Pennsylvania time, on the next succeeding Business Day, deliver to
the Agent such Bank's Ratable Share of such payment as a TEC Revolving Credit
Loan from such Bank in immediately available funds.

                  2.9.5 DOCUMENTATION.

                  TEC agrees to be bound by the terms of the Agent's application
and agreement for letters of credit and the Agent's written regulations and
customary practices relating to letters of credit, though such interpretation
may be different from TEC's own. In the event of a conflict between such
application or agreement and this Agreement, this Agreement shall govern
(provided that terms of the Agent's application and agreement for letters of
credit which are in addition to those contained herein and which do not
expressly conflict with the terms contained herein shall be deemed not to be in
conflict with this Agreement). It is understood and agreed that, except in the
case of gross negligence or willful misconduct, the Agent shall not be liable
for any error, negligence and/or mistakes, whether of omission or commission, in
following TEC's instructions or those contained in the Letters of Credit issued
by the Agent or any modifications, amendments or supplements thereto.

                  2.9.6 DETERMINATIONS TO HONOR DRAWING REQUESTS.

                  In determining whether to honor any request for drawing under
any Letter of Credit by the beneficiary thereof, the Agent shall be responsible
only to determine that the documents and certificates required to be delivered
under such Letter of Credit have been delivered and that they appear to comply
on their face with the requirements of such Letter of Credit.

                  2.9.7 NATURE OF PARTICIPATION AND REIMBURSEMENT OBLIGATIONS.

                  The obligation of the Banks to participate in Letters of
Credit pursuant to Section 2.9.2 and the obligation of the Banks pursuant to
Section 2.9.4 to fund TEC Revolving Credit Loans upon a draw under a Letter of
Credit or to make Participation Advances in Letters of Credit and the
Obligations of TEC to reimburse the Agent upon a draw under any Letter of Credit
pursuant to Section 2.9 shall be absolute, unconditional and irrevocable, and

                                    TEC Revolving Credit Loan, it being
                                    acknowledged that such conditions are not
                                    required for the making of a TEC Revolving
                                    Credit Loan under Section 2.9.4;

                           (ii)     any lack of validity or enforceability of

                                    was procured);

                           (v)      payment by the Agent under any Letter of

honor a drawing under any such Letter of Credit as a result of any act or
omission, whether rightful or wrongful, of any present or future de jure or de
facto government or governmental authority (all such acts or omissions herein
called "Governmental Acts").

                  2.9.9 LIABILITY FOR ACTS AND OMISSIONS.

                  As between any Borrower and the Agent, such Borrower assumes
all risks of the acts and omissions of, or misuse of the Letters of Credit by,
the respective beneficiaries of the Letters of Credit. In furtherance and not in
limitation of the foregoing, neither the Agent nor any Bank shall be responsible
for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect
of any document submitted by any party in connection with the application for
issuance of any Letter of Credit issued by the Agent, even if it should in fact
prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent
or forged (even if the Agent shall have been notified thereof); (ii) the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign any such Letter of Credit or the rights or
benefits thereunder or proceeds thereof, in whole or in part, which may prove to
be invalid or ineffective for any reason; (iii) failure of the beneficiary of
any such Letter of Credit to comply fully with any conditions required in order
to draw upon such Letter of Credit; (iv) errors, omissions, interruptions or
delays in transmission or delivery of any messages, by mail, cable, telegraph,
telex or otherwise, whether or not they be in cipher; (v) errors in
interpretation of technical terms; (vi) any loss or delay in the transmission or
otherwise of any document required in order to make a drawing under any such
Letter of Credit or of the proceeds thereof; (vii) the misapplication by the
beneficiary of any such Letter of Credit of the proceeds of any drawing under
such Letter of Credit; or (viii) any consequences arising from causes beyond the
control of the Agent, including any Governmental Acts, and none of the above
shall affect or impair, or prevent the vesting of, any of the Agent's rights or
powers hereunder.

                  In furtherance and extension and not in limitation of the
specific provisions set forth above, any action taken or omitted by the Agent
under or in connection with the Letters of Credit issued by it or any documents
and certificates delivered thereunder, if taken or omitted in good faith, shall
not put the Agent under any resulting liability to TEC or any Banks.

                  No Bank or Consolidated TEC Group Entity may commence a
proceeding against the Agent for wrongful disbursement under a Letter of Credit
issued by the Agent as a result of acts or omissions constituting gross
negligence or willful misconduct of the Agent, until the Banks have made and the
Borrowers have repaid the Revolving Credit Loans described in Section 2.9.4;
provided, however, that nothing in this Section 2.9.9 shall adversely affect the
right of TEC, after such payment, to commence any proceeding against the Agent
for any breach of its obligations hereunder.

            2.10 BANK GUARANTEE SUBFACILITY FOR CIH.

                  2.10.1 ISSUANCE OF BANK GUARANTEES ON BEHALF OF CIH.

                  CIH may request the Agent's London Office to issue one or more
Bank Guarantees (each a "Bank Guarantee" and collectively, the "Bank
Guarantees") in favor of nominated beneficiaries to guarantee CIH's liability
for deferred purchase consideration arising out of the closing of the Ultra
Acquisition or for other corporate purposes by delivering to the Agent at its
London Office by no later than 12:00 p.m., London time at least three Business
Days before the requested date of issuance of the relevant Bank Guarantee a
written notice (a "Request") in substantially the form of EXHIBIT 2.10.1
specifying the proposed beneficiary, date of issuance, the expiry date of the
Bank Guarantee, the nature of the transactions to be supported thereby and
whether or not the guaranteed liability is to be in Dollars or Pounds Sterling.
Subject to the terms and conditions of this Agreement and provided that at the
time of the delivery of the relevant Request and upon the proposed date of
issuance (a) the representations and warranties set out in Section 6 of this
Agreement are true and correct on and as of each such time as if each were made
with reference to the facts and circumstances existing at such time, and (b) no
Event of Default or Potential Default shall have occurred and be continuing or
would result from the issuance of the relevant Bank Guarantee, the Agent's
London Lending Office will issue the relevant Bank Guarantee.

                  2.10.2 RESTRICTIONS ON BANK GUARANTEES.

                  Each Bank Guarantee shall (A) expire no later than 365 days
from and including its date of issuance; and (B) not expire later than five (5)
Business Days prior to the Expiration Date. In any event, Bank Guarantee
Outstandings (i) shall not exceed at any one time the sum of the Bank Guarantees
issued in connection with the consummation of the Ultra Acquisition, plus the
equivalent in Pounds Sterling of $2,000,000 (measured at the time of incurrence)
with respect to Bank Guarantees not used in connection with the Ultra
Acquisition and (ii) the sum of the Bank Guarantee Outstandings, CIH Revolving
Credit Loans and CIH Bid Loans then outstanding shall not, at any one time,
exceed the CIH Revolving Credit Commitments.

                  2.10.3 PARTICIPATIONS.

                  Immediately upon the issuance of any Bank Guarantee, and
without further action, each Bank shall be deemed to, and hereby agrees that it
shall, have irrevocably purchased for such Bank's Revolving Credit own account
and risk from the Agent an individual participation interest in such Bank
Guarantee in an amount equal to such Bank's Revolving Credit Ratable Share of
the maximum amount of the Agent's liability under such Bank Guarantee, and each
Bank shall reimburse the Agent immediately for its Revolving Credit Ratable
Share of any payment by the Agent of its liability under any Bank Guarantee
which has not been reimbursed by CIH in accordance with Section 2.10.5.



                                      -40-
<PAGE>   50

                  Upon the request of any Bank and no less frequently than once
in each calendar month, the Agent shall notify each Bank of the amount of such
Bank's participation in Bank Guarantees.

                  2.10.4 BANK GUARANTEE FEES.

                  CIH shall pay to the Agent in Dollars into such account as the
Agent may nominate in writing from time to time for the ratable account of the
Banks fees ("Bank Guarantee Fee") with respect to Bank Guarantee Outstandings in
an amount equal to such Bank Guarantee Outstandings multiplied by a rate per
annum (computed on the basis of a year of 365 days and actual days elapsed) as
specified in the definition of Applicable Margin for Bank Guarantees, for the
applicable period specified in such definition, payable quarterly in arrears on
the first Business Day of each of January, April, July and October following the
Closing Date and on the earlier of the Expiration Date or the date upon which
any demand is made for the repayment of the Loans. Such rates (per annum) of the
Bank Guarantee Fees shall change on the effective date of any change in the
Applicable Margin.

                  CIH shall also pay to the Agent in the same manner and
currency as it shall pay the Bank Guarantee Fee for its sole account (i) a
fronting fee equal to 0.125% per annum of the aggregate guarantee liability of
the Agent under each Bank Guarantee issued, payable quarterly in arrears, and
(ii) all administrative and other costs and expenses incurred by the Agent in
connection with the issuance, maintenance, modification, assignment, transfer,
negotiation and administration of any Bank Guarantee, payable upon request from
the Agent.

                  2.10.5 COUNTER-INDEMNITIES.

                  CIH unconditionally and irrevocably agrees and undertakes to
the Agent and each of the Banks that:

                  (A) it will pay the Agent, on demand and in the currency in
                  which such amount shall have been demanded, made, suffered or
                  incurred, an amount equal to all payments made, suffered or
                  incurred by it (whether by direct payment or by way of
                  set-off, counterclaim or otherwise) under or in respect of any
                  Bank Guarantee; and

                  (B) it will at all times reimburse and indemnify the Agent and
                  each of the Banks and keep each of them indemnified, as
                  primary obligor and not merely as surety, and notwithstanding
                  the insufficiency, illegality or unenforceability of any Bank
                  Guarantee, from and against all actions, proceedings, claims,
                  liabilities, damages, losses, costs, charges and expenses
                  (including reasonable legal fees and disbursements, whether of
                  internal or external counsel) whatsoever in relation to or
                  arising out of each Bank Guarantee and/or its participation
                  therein, including without limitation any amount paid by any
                  Bank under Section 2.10.6, other than 


                                      -41-

<PAGE>   51
                  as a result of the gross negligence or willful misconduct of
                  the Agent (as determined by a final judgment of a court of
                  competent jurisdiction).

                  CIH and each of the Banks hereby irrevocably authorizes the
Agent to comply with the terms of and make any payment in accordance with any
demand made or appearing or purporting to be made on the Agent pursuant to any
Bank Guarantee without any reference to, or further authority from, and despite
any objection by, CIH or any Bank and without any inquiry by the Agent into the
justification for or validity of such demand. CIH agrees that any payment which
the Agent shall make in accordance or purporting to be in accordance with such a
demand shall be binding on CIH and the Banks and be accepted by them as
conclusive and binding evidence that the Agent was liable to comply with the
terms of such demand, in the manner and the amount demanded.

                  The obligations and liability of CIH under this Section 2.10.5
shall not be affected or impaired by (a) any waiver or time or indulgence
granted to or by the Agent; (b) any release or dealings with any rights or
security of the Agent; (c) any invalidity of any Bank Guarantee; (d) any
variation or extension of any Bank Guarantee provided that such variation or
extension shall have been approved by CIH and the Agent respectively; or (e) any
other circumstances which might but for this provision affect or impair, or
exonerate or discharge CIH from, such obligations or liability.

                  The indemnity contained in this Section shall constitute and
be a continuing security to the Agent and each of the Banks and shall be in
addition to, and shall not prejudice or be prejudiced by, any other security,
guarantee, indemnity, lien or other right of the Agent or any Bank.

                  CIH will forthwith inform the Agent of all facts or
circumstances of which it is or becomes aware which may result in any claim or
demand being made on the Agent under any Bank Guarantee.

                  Neither CIH nor any Bank may make any claim or commence a
proceeding against the Agent for wrongful payment under a Bank Guarantee arising
from the Agent's gross negligence or willful misconduct unless and until the
relevant Bank or Banks or CIH (as applicable) has made all such payments to the
Agent as are required pursuant to this Section 2.10.5 or Section 2.10.6.

                  2.10.6 CLAIMS UNDER BANK GUARANTEES.

                  If any claim or demand is made under a Bank Guarantee being or
purporting to be in accordance with its terms, the Agent shall promptly notify
CIH and each Bank, specifying:

                  (A) the Bank Guarantee in respect of which the claim or demand
                  has been made;


                                      -42-
<PAGE>   52


                  (B) the date on which payment is to be made; and

                  (C) the aggregate amount and currency of the claim or demand
                  and each Bank's participation in such amount.

                  If CIH fails to pay any amount to the Agent on demand under
Section 2.10.5, the Agent shall promptly notify each of the Banks. Each of the
Banks shall, if so notified under this paragraph, pay in accordance with Section
2.10.5 and by way of indemnity to the Agent for the Agent's account, not later
than 12:00 noon, London time on the due date for payment under the relevant Bank
Guarantee in immediately available funds, its Revolving Credit Ratable Share of
the amount which CIH has so failed to pay.

         2.11 TERM FACILITY.

                  2.11.1 TERM LOAN COMMITMENTS.

                  Subject to the terms and conditions hereof and relying upon
the representations and warranties herein set forth, each Bank severally agrees
to make a term loan (the "Term Loan") to TEC on the Closing Date in an amount
equal to such Bank's Term Loan Commitment.

                  2.11.2 NATURE OF BANKS' OBLIGATIONS WITH RESPECT TO TERM
LOANS.

                  The obligations of each Bank to make a Term Loan to TEC shall
be in the proportion that such Bank's Term Loan Commitment bears to the Term
Loan Commitments of all Banks to TEC, but each Bank's Term Loan to TEC shall
never exceed its Term Loan Commitment. The failure of any Bank to make a Term
Loan shall not relieve any other Bank of its obligations to make a Term Loan nor
shall it impose any additional liability on any other Bank hereunder. The Banks
shall have no obligation to make Term Loans hereunder after the Closing Date.
The Term Loan Commitments are not revolving credit commitments and TEC shall not
have the right to borrow, repay and reborrow under Section 2.11.1.

                  2.11.3 TERM LOAN NOTES.

                  The obligation of TEC to repay the unpaid principal amount of
the Term Loan made to it by each Bank, together with interest thereon, shall be
evidenced by a promissory note of TEC dated the Closing Date in substantially
the form attached hereto as EXHIBIT 1.1(T) payable to the order of each Bank in
a face amount equal to the Term Loan Commitment of such Bank. The outstanding
principal amount of the Term Notes shall be payable in the following
installments:

refinance existing indebtedness owed by it to Mellon Bank, N.A. and for other
general corporate purposes.

                           3. COMPETITIVE BID FACILITY

         3.1 BID LOAN REQUESTS.

         Except as otherwise provided herein, each Borrower may from time to

on a year of 365 or 366 days) specified by the Bank making such Bid Loan in its
Bid (a "Fixed Rate Bid Loan") or (B) the applicable Euro-Rate plus or minus a
margin (the "Margin") (which shall be expressed as a percentage rate per annum
in the form of a decimal to no more than four decimal places and based on a year

the case of TEC Bid Loans, or a year of 365 days in the case of CIH Bid Loans)
as specified by the Bank making such Bid Loan in its Bid (a "Euro-Rate Bid
Loan");

                  (iii) the term of the proposed Bid Loan (the "Bid Loan
Interest Period"), which may be (A) no less than seven (7) days and no longer
than ninety (90) days in the case of a Fixed Rate Bid Loan, or (B) one, two or
three Months in the case of a Euro-Rate Bid Loan; and in all cases, such term

integral multiple of $1,000,000, in the case of TEC Bid Loans, and (ii) not less
than (pound)1,000,000 and shall be an integral multiple of (pound)500,000 in the

         3.2 BIDDING FOR, ACCEPTING AND MAKING BID LOANS.

                  3.2.1 BIDDING.

                  The Agent shall promptly after receipt by it of a Bid Loan

Request, specifying (i) the proposed Borrower and Borrowing Date, (ii) the Bid
Loan Interest Period, (iii) the principal amount of the proposed Bid Loan and
(iv) whether such Bid Loan is to be a Euro-Rate Bid Loan or a Fixed Rate Bid
Loan. Each Bank may submit a bid (a "Bid") to the Agent at the Applicable
Lending Office by telephone (immediately confirmed in writing in the form of
EXHIBIT 3.2 by letter, facsimile or telex) not later than 10:00 A.M. Pittsburgh
time or London time (as applicable) on the proposed Borrowing Date specified in
the Bid Loan Request in the case of a Fixed Rate Bid Loan and 10:00 A.M.
Pittsburgh or London time (as applicable) three (3) Business Days before the
proposed Borrowing Date in the case of a Euro-Rate Bid Loan. Each Bid shall

(the "Offered Amount"), which (i) may be less than, but shall not exceed, the
Requested Amount, 


                                      -45-
<PAGE>   55

(ii) shall be at least $2,000,000 (or the Dollar Equivalent) and shall be an
integral multiple of $500,000 (or the Dollar Equivalent) if it is a Euro-Rate
Bid Loan or an integral multiple or $500,000 if it is a Fixed Rate Bid Loan, and
(iii) may exceed such Bank's Commitment, and (B) the interest rate in the case
of a Fixed Rate Bid Loan or the Margin in the case of a Euro-Rate Bid Loan
applicable to such proposed Bid Loan offered by such Bank. If any Bid omits
information required hereunder, the Agent may in its sole discretion attempt to
notify the Bank submitting such Bid. If the Agent so notifies a Bank, such Bank
may resubmit its Bid, provided that it does so prior to 10:00 A.M. Pittsburgh
time or London time (as applicable) on the Borrowing Date in the case of a Fixed
Rate Bid Loan or 10:00 A.M. Pittsburgh or London time (as applicable) three (3)
Business Days before the Borrowing Date in the case of a Euro-Rate Bid Loan. The
Agent shall promptly notify the Borrower of each Bid provided that the Agent has
received such Bid on or before 10:00 A.M. Pittsburgh time or London time (as
applicable) on the Borrowing Date in the case of a Fixed Rate Bid Loan or 10:00
A.M. Pittsburgh or London time (as applicable) three (3) Business Days before
the Borrowing Date in the case of a Euro-Rate Bid Loan. If the Agent in its
capacity as a Bank shall, in its sole discretion, make a Bid, it shall notify
the Borrower of such Bid before 9:30 A.M. Pittsburgh time or London time (as
applicable) on the Borrowing Date in the case of a Fixed Rate Bid Loan or 9:30
A.M. Pittsburgh or London time (as applicable) three (3) Business Days before
the Borrowing Date in the case of a Euro-Rate Bid Loan.

                  3.2.2 ACCEPTING BIDS.

                  The requesting Borrower shall, in its sole discretion,
irrevocably accept or reject any one or all of the Bids and shall notify the
Agent at the Applicable Lending Office of its acceptance or rejection by
telephone (immediately confirmed in writing by letter, facsimile or telex). If
the Borrower elects to accept any Bids, its acceptance must meet the following
conditions: (1) such acceptance must be received by Agent by 11:30 A.M.
Pittsburgh time or London time (as applicable) on the Borrowing Date if the
Borrower is accepting a Bid for a Fixed Rate Bid Loan and by 11:30 A.M.
Pittsburgh or London time (as applicable) three (3) Business Days before the
Borrowing Date if the Borrower is accepting a Bid for a Euro-Rate Bid Loan; (2)
the total amount which the Borrower accepts from all Banks must equal or exceed
$1,000,000 and be in an integral multiple of $500,000 (or in each case as
applicable, the Dollar Equivalent) if it is a Euro-Rate Bid Loan or an integral
multiple of $500,000 if it is a Fixed Rate Bid Loan and in either instance may
not exceed the Requested Amount; (3) the Borrower must accept Bids based solely
on the amount of the interest rates of each Bid in ascending order of the amount
of such interest rates; (4) the Borrower may not borrow Bid Loans from any Bank
on the relevant Borrowing Date in an amount exceeding such Bank's Offered
Amount; (5) if two or more Banks make Bids at the same interest rate and the
Borrower desires to accept a portion but not all of the Bids at such interest
rate, the Borrower shall accept a portion of each such Bid equal to the product
of the Offered Amount of each such Bid times the fraction obtained by dividing
the total amount of Bids which the Borrower is accepting at such interest rate
by the sum of the Offered Amounts of the Bids at such rate; PROVIDED that the
Borrower shall round the Bid Loan allocated to each such Bank upward or downward
as the Borrower may select to an integral multiple of $500,000 (or the Dollar
Equivalent). The Agent shall (i) promptly notify a

Bank that has made a Bid of the amount of its Bid that was accepted or rejected
by the Borrower and (ii) as promptly as practical notify all of the Banks of all
Bids submitted and those which have been accepted.

                  3.2.3 FUNDING BID LOANS.

                  Each Bank whose Bid or portion thereof is accepted shall remit
the principal amount of its Bid Loan to the Agent at its Applicable Lending
Office by 1:00 P.M. Pittsburgh time or 12:00 P.M. London time (as applicable) on
the Borrowing Date. The Agent shall make such funds available to the Borrower on
or before 2:00 P.M. on the Borrowing Date provided that the conditions precedent
to the making of such Bid Loan set forth in Section 7.3 have been satisfied not
later than 10:00 A.M. Pittsburgh time or London time (as applicable) on the
proposed Borrowing Date. The Agent may assume that the applicable Borrower has
satisfied such conditions precedent if such Borrower has not notified the Agent
that such Borrower has not satisfied any conditions precedent.

                  3.2.4 SEVERAL OBLIGATIONS.

                  The obligations of the Banks to make Bid Loans after their

failure of any other Bank to make any Bid Loan which another Bank has agreed to
make.

                  3.2.5 BID LOAN INTEREST PERIODS.

                  If any Bid Loan Interest Period for a Euro-Rate Bid Loan
Option is scheduled to end on a date which is not a Business Day, such Bid Loan
Interest Period shall be extended to the next succeeding Business Day unless
such Business Day falls in the next calendar month, in which case such Bid Loan
Interest Period shall end on the next preceding Business Day.

         3.3 BID LOAN NOTES.

         The obligation of each Borrower to repay the aggregate unpaid principal
amount of the Bid Loans made to it by each Bank, together with interest thereon,
shall be evidenced by a Bid Loan Note dated as of the Closing Date payable to
the order of such Bank in a face amount equal to the aggregate Revolving Credit
Commitments of all of the Banks to such Borrower.

                               4. INTEREST RATES

         4.1 INTEREST.

         Each Borrower shall pay interest in respect of the outstanding unpaid
principal amount of such Loans as selected by it from the Base Rate Option or
Euro-Rate Option set forth below applicable to the Loans, it being understood
that, subject to the provisions of this Agreement, the Borrowers may select
different Interest Rate Options and different Interest 



                                      -47-
<PAGE>   57



Periods to apply simultaneously to the Loans comprising different Borrowing
Tranches and may convert to or renew one or more Interest Rate Options with
respect to all or any portion of the Revolving Credit Loans or Term Loans
comprising any Borrowing Tranche by delivering to the Agent at the applicable
Lending Office a duly completed Loan Request by the time described in Section
2.5 for conversion or renewal of such Interest Rate Option for a Revolving
Credit, PROVIDED that there shall not be at any one time outstanding (i) more
than twelve (12) Borrowing Tranches in the aggregate for all the Loans to TEC or
(ii)more than four (4) Borrowing Tranches in the aggregate for all the Loans to
CIH. If at any time the designated rate applicable to any Loan made by any Bank
exceeds such Bank's highest lawful rate, the rate of interest on such Bank's
Loan shall be limited to such Bank's highest lawful rate. 

                  4.1.1 INTEREST RATE OPTIONS.

                  (i) The TEC Revolving Credit Loans and the Term Loans shall
accrue interest at the US Base Rate Option or at the US Euro-Rate Option as
selected by TEC in accordance with the provisions of this Agreement; and

                  (ii) The CIH Revolving Credit Loans shall accrue interest at
the UK Base Rate Option or the UK Euro-Rate Option as selected by CIH in
accordance with the provisions of this Agreement.

         4.2 REVOLVING CREDIT LOAN INTEREST PERIODS.

         The Interest Period specified in a Loan Request during which a Euro
Rate Option shall apply shall be one, two, three or six Months and as additional
periods, with respect to CIH Revolving Credit Loans only, one, two, or three
weeks; PROVIDED that prior to the Business Day following the Syndication Date,
no Interest Period may be longer than one month, and provided FURTHER, that:

                  4.2.1 ENDING DATE AND BUSINESS DAY.

                  Any such Interest Period which would otherwise end on a date
which is not a Business Day shall be extended to the next succeeding Business
Day unless such Business Day falls in the next calendar month, in which case
such Interest Period shall end on the next preceding Business Day;

                  4.2.2 AMOUNT OF BORROWING TRANCHE.

                  Each Borrowing Tranche of a Loan to which the Euro-Rate Option
applies shall be in integral multiples of (i) $1,000,000 and not less than
$5,000,000, with respect to TEC and (ii) (pound)500,000 and not less than
(pound)1,000,000, with respect to CIH;



                                      -48-
<PAGE>   58

                  4.2.3 TERMINATION BEFORE EXPIRATION DATE.

                  The Borrowers shall not select, convert to or renew an
Interest Period for any portion of the Loans that would end after the Expiration
Date; and

                  4.2.4 RENEWALS.

                  In the case of the renewal of a Euro-Rate Option at the end of
an Interest Period, the first day of the new Interest Period shall be the last
day of the preceding Interest Period, without duplication in payment of interest
for such day.

         4.3 INTEREST AFTER DEFAULT.

         To the extent permitted by Law, upon the occurrence of an Event of
Default and until such time such Event of Default shall have been cured or
waived:

                  4.3.1 LETTERS OF CREDIT FEES, BANK GUARANTEE FEES, INTEREST
RATE.

                  The Letters of Credit Fees, the Bank Guarantee Fees and the
rate of interest for each Loan otherwise applicable pursuant to Section 2.9.3,
2.10.4 or Section 4.1, respectively, shall be increased by 2.0% per annum;

                  4.3.2 OTHER OBLIGATIONS.

                  Each other Obligation hereunder if not paid when due shall
bear interest at a rate per annum equal to the sum of the rate of interest
applicable under the US Base Rate Option plus an additional 2.0% per annum from
the time such Obligation becomes due and payable and until it is paid in full;
and

                  4.3.3 ACKNOWLEDGMENT.

                  The Borrowers acknowledge that the increased rates referred to
in this Section 4.3 reflect, among other things, the fact that the Loans or
other amounts have become a substantially greater risk given their default
status and that the Banks are entitled to additional compensation for such risk.
All such interest payable by a Borrower shall be paid by it upon demand by the
Agent.

         4.4 EURO-RATE UNASCERTAINABLE.

                  4.4.1 UNASCERTAINABLE.

                  If on any date on which a Euro-Rate would otherwise be
determined, the Agent shall have determined that:

                        (i)   adequate and reasonable means do not exist for
                              ascertaining such Euro-Rate, or



                                      -49-
<PAGE>   59

                        (ii)  a contingency has occurred which materially and
                              adversely affects the London interbank market
                              relating to the Euro-Rate,

then the Agent shall have the rights specified in Section 4.4.3.

                  4.4.2 ILLEGALITY; INCREASED COSTS; DEPOSITS NOT AVAILABLE.

                  If at any time any Bank shall have determined that:

                        (i)   the making, maintenance or funding of any Loan to
                              which a Euro-Rate Option applies has been made
                              impracticable or unlawful by compliance by such
                              Bank in good faith with any Law or any
                              interpretation or application thereof by any
                              Official Body or with any request or directive of
                              any Official Body (whether or not having the force
                              of Law), or

                        (ii)  such Euro-Rate Option will not adequately and
                              fairly reflect the cost to such Bank of the
                              establishment or maintenance of any such Loan, or

                        (iii) in relation to any Drawing made in US Dollars and
                              after making all reasonable efforts, deposits of
                              the relevant amount in Dollars for the relevant
                              Interest Period for a Loan to which a Euro-Rate
                              Option applies, are not available to such Bank
                              with respect to such Loan in the London interbank
                              market,

then, subject to the provisions of Section 11.5.3, such Bank shall have the
rights specified in Section 4.4.3.

                  4.4.3 AGENT'S AND BANK'S RIGHTS.

                  In the case of any event specified in Section 4.4.1, the Agent
shall promptly so notify the Banks and the Borrowers thereof, and in the case of
a determination specified in Section 4.4.2, such Bank shall promptly so notify
the Agent and endorse a certificate to such notice as to the specific
circumstances of such notice, and the Agent shall promptly send copies of such
notice and certificate to the other Banks and the Borrowers. Upon such date as
shall be specified in such notice (which shall not be earlier than the date such
notice is given) the obligation of (A) the Banks, in the case of such notice
given by the Agent in respect of Section 4.4.1, or (B) such Bank, in the case of
such notice given by such Bank in respect of Section 4.4.2, to allow the
applicable Borrower to select, convert to or renew a Euro-Rate Option shall be
suspended until the Agent shall have later notified the applicable Borrower, or
such Bank shall have later notified the Agent, of the Agent's or such Bank's, as
the case may be, determination that the circumstances giving rise to such
previous determination no longer exist. 


                                      -50-
<PAGE>   60

If at any time the Agent makes a determination under Section 4.4.1 and either
Borrower has previously notified the Agent of its selection of, conversion to or
renewal of a Euro-Rate Option and such Interest Rate Option has not yet gone
into effect, such notification shall be deemed to provide for selection of,
conversion to or renewal of the Base Rate Option otherwise available with
respect to the affected Loans. If any Bank notifies the Agent of a determination
under Section 4.4.2, the applicable Borrower shall, subject to such Borrower's
indemnification Obligations under Section 5.6.2, as to any Loan of such Bank to
which a Euro-Rate Option applies, on the date specified in such notice convert
such Loan to the Base Rate Option otherwise available with respect to such Loan.
Absent due notice from the applicable Borrower of conversion, such Loan shall
automatically be converted to the Base Rate Option otherwise available with
respect to such Loan upon such specified date. Upon any such conversion, the
applicable Borrower shall have the right to prepay Loans in the amount of such
Loan on the date of such conversion without providing the notice otherwise
required by Section 5.4.1. If an event occurs that makes the applicable
Euro-Rate Option no longer available to a Borrower, such Borrower, the Agent and
the Banks shall negotiate in good faith to provide a replacement Interest Rate
Option for the affected Euro-Rate Option that is mutually satisfactory.

         4.5 SELECTION OF INTEREST RATE OPTIONS.

         If a Borrower fails (i) to select a new Interest Period to apply to any
Borrowing Tranche to which a Euro-Rate Option applies at the expiration of an
existing Interest Period applicable to such Borrowing Tranche in accordance with
the provisions of Section 4.2, or (ii) to select the Base Rate Option otherwise
available with respect to such Loan, TEC shall be deemed to have converted such
Borrowing Tranche to such Base Rate Option commencing upon the last day of such
Interest Period and CIH shall be deemed to have converted such Borrowing Tranche
to the UK Euro Rate Option for a one month Interest Period.

                                  5. PAYMENTS

         5.1 PAYMENTS.

         All payments and prepayments to be made in respect of principal,
interest, Commitment Fees, Letters of Credit Fees, the Agent's Fee, or other
amounts due from the Borrowers hereunder (other than the fees and expenses

provided in such Sections and the fees and expenses referenced in Section 10.15,
each of which shall be paid in accordance with such Sections) shall be payable

London Office or (ii) 12:00 p.m., Pittsburgh, Pennsylvania time, with respect to
all payments to be made at the Principal Office, on the date when due without
presentment, demand, protest or notice of any kind, all of which are hereby
expressly waived by such Borrower, and without set-off, counterclaim or other
deduction of any nature, and an action therefor shall immediately accrue to the
extent of any non-payment thereof. Payments of principal and interest on Loans
and of Commitment Fees, Letters of Credit Fees and Bank Guarantee Fees shall be
made to the Agent at the Applicable Lending Office (or as the Agent may direct
in writing from time to time) 


                                      -51-
<PAGE>   61


for the ratable accounts of the Banks in Dollars or (as applicable) Pounds
Sterling and in immediately available funds, and the Agent shall promptly
distribute such amounts to the Banks in immediately available funds; provided
that in the event payments are received by (x) 11:00 a.m., London time, with
respect to payments to be made at the London Office or (y) 12:00 p.m.
Pittsburgh, Pennsylvania time, with respect to all payments to be made at the
Principal Office, in the Applicable Lending Office by the Agent (or as the Agent
may have directed) with respect to the Loans and such payments are not
distributed to the Banks on the same day received by the Agent, the Agent shall
pay the Banks the Federal Funds Effective Rate with respect to the amount of
such payments for each day held by the Agent and not distributed to the Banks.
The Agent's and each Bank's statement of account, ledger or other relevant
record shall, in the absence of manifest error, be conclusive as the statement
of the amount of principal of and interest on the Loans and other amounts owing
under this Agreement and shall be deemed an "account stated."

         5.2 PRO RATA TREATMENT OF BANKS.

                  5.2.1 REVOLVING CREDIT LOANS.

                  Each borrowing of a Revolving Credit Loan shall be allocated
to each Bank according to its Revolving Credit Ratable Share, and each selection
of, conversion to or renewal of any Interest Rate Option and each payment or
prepayment by a Borrower with respect to principal, interest, Commitment Fees
related to the Revolving Credit Loans, Letters of Credit Fees, Bank Guarantee
Fees, or other fees (except for the Agent's Fee, and any fees to the Agent with
respect to the issuance, administration or payments under Letters of Credit or
Bank Guarantees) or amounts due from a Borrower hereunder to the Banks with
respect to Revolving Credit Loans to it, shall (except as provided in Section
4.4.2 [Illegality, Increased Costs; Deposits not Available], 5.4 [Voluntary
Prepayments] or 5.6 [Additional Compensation in Certain Circumstances]) be made
in proportion to the applicable Revolving Credit Loans to both Borrowers
outstanding from each Bank and, if no such Revolving Credit Loans are then
outstanding, in proportion to the Revolving Credit Ratable Share of each Bank.

                  5.2.2 TERM LOANS.

                  Each selection of, conversion to or renewal of any Interest
Rate Option and each payment or prepayment by TEC with respect to principal,
interest, Commitment Fees related to the Term Loans, or amounts due from TEC
hereunder to the Banks with respect to Term Loans to it, shall (except as
provided in Section 4.4.2 [Illegality, Increased Costs; Deposits not Available],
5.4 [Voluntary Prepayments] or 5.6 [Additional Compensation in Certain
Circumstances]) be made in proportion to the applicable Term Loans outstanding
from each Bank.

         5.3 INTEREST PAYMENT DATES.

         Interest on Loans to which a Base Rate Option applies shall be due and
payable in arrears on the first Business Day of each January, April, July and
October after the date hereof 


                                      -52-

Interest Period for those Loans and, if any such Interest Period is longer than
three Months, also on the last day of every third Month during such Interest
Period. Interest on Fixed Rate Bid Loans shall be due and payable in arrears on
the first Business Day of each January, April, July and October and at the

mandatory prepayment is due. Interest on the principal amount of each Loan or
other monetary Obligation shall be due and payable on demand after such
principal amount or other monetary Obligation becomes due and payable (whether
on the stated maturity date, upon acceleration or otherwise).

         5.4 VOLUNTARY PREPAYMENTS.

                  5.4.1 RIGHT TO PREPAY.

                  Each Borrower shall have the right at its option from time to
time to prepay its respective portion of the Loans in whole or part without
premium or penalty (except as provided in Section 5.6):

                        (i)   at any time with respect to any Loan to which the
                              Base Rate Option applies,

                        (ii)  on the last day of the applicable (A) Interest
                              Period with respect to Loans (other than Loans
                              described in subclause (B) hereof)to which a
                              Euro-Rate Option applies or (B) Bid Loan Interest
                              Period with respect to Bid Loans to which a
                              Euro-Rate Option or a Bid Loan Fixed Rate Option
                              applies, and

                        (iii) on the date specified in a notice by any Bank
                              pursuant to Section 4.4 [Euro-Rate
                              Unascertainable], with respect to any Loan to
                              which a Euro-Rate Option applies.

                  Whenever a Borrower desires to prepay any part of the Loans,
it shall provide a prepayment notice to the Agent not later than 10:00 a.m.,
Pittsburgh or London time (as applicable) in the Applicable Lending Office on
the Business Day prior to the date of prepayment of Loans setting forth the
following information (provided no notice from the applicable Borrower is
required pursuant to subsection (iii) above):

                  (w)   the date,  which  shall be a Business  Day, on which the
            proposed prepayment is to be made;

                                      -53-
<PAGE>   63


                  (x) a statement indicating the application of the prepayment
            to the Revolving Credit Loans, Bid Loans and/or Term Loans;

                  (y) the total principal amount of such prepayment, which shall
            not be less than $1,000,000 (or the Dollar Equivalent) or integral
            multiples thereof; and

                  (z) if applicable, that such prepayment is intended as an
            early payment of Excess Consideration (as defined in Section 8.2.6)
            to be credited against any mandatory prepayment that may become due
            with respect thereto pursuant to Sections 8.2.6 and 5.5.1.

                  All prepayment notices shall be irrevocable. The principal
amount of the Loans for which a prepayment notice is given, together with
interest on such principal amount shall be due and payable on the date specified
in such prepayment notice as the date on which the proposed prepayment is to be
made. If a Borrower prepays a Loan pursuant to this Section but fails to specify
the applicable Borrowing Tranche which such Borrower is prepaying, the
prepayment shall be applied first to Loans to which the Base Rate Option
applies, then to Loans to which the Bid Loan Fixed Rate Option applies, then to
Loans to which the Euro-Rate Option applies. If TEC prepays a Loan pursuant to
this Section but fails to specify whether the TEC Bid Loans, Term Loans or TEC
Revolving Credit Loans are being prepaid, unless the prepayment notice contains
the information in clause (z) above, the prepayment shall be applied first to
TEC Revolving Credit Loans, then to TEC Bid Loans and then to the Term Loans.
All prepayments, other than mandatory prepayments pursuant to Section 5.5.1 and
Section 8.2.6, applied to the Term Loans shall be applied to the then remaining
installments due in the order of maturity thereof. If such prepayment notice
contains the information in clause (z) above, then, whether or not TEC has
specified the application of such prepayment, such prepayment shall be applied
to Term Loans in the manner set forth in Section 5.5.1. Upon any voluntary
prepayment of Term Loans pursuant to this Section 5.4, the Term Loan Commitments
shall be automatically and permanently reduced in an amount equal to the amount
of the prepayment of the Term Loans. Any prepayment hereunder shall be subject
to the Borrower's Obligation to indemnify the Banks under Section 5.6.2.

         5.5 MANDATORY REDUCTION OF COMMITMENTS; MANDATORY PAYMENTS AND
             PREPAYMENTS.

                  5.5.1 SALE OF ASSETS.

                  Within five (5) Business Days after the end of any fiscal year
of TEC in which insufficient Qualified Investments were made so as to require a
prepayment pursuant to Section 8.2.6, TEC shall make a mandatory prepayment of
principal on the Term Loans (together with accrued interest on such principal
amount) equal to the lesser of (i) the amount of the prepayment so required or
(ii) the amount of the outstanding Term Loans, provided, however, that no such
prepayment shall be required (x) if and to the extent that TEC shall have made a
prepayment of the type described in clause (z) of Section 5.4 or (y) with
respect to the disposition described in clause (iv) of Section 8.2.6, the time
described in the final sentence of such Section 


                                      -54-
<PAGE>   64


8.2.6. All proceeds received for prepayment of Term Loans pursuant to this
Section 5.5.1 or pursuant to clause (z) of Section 5.4 shall be applied to the
payment PRO RATA of each of the then remaining scheduled installments of
principal. Further, all proceeds received for prepayment of Loans pursuant to
this Section 5.5.1 shall be first applied to Loans to which the US Base Rate
Option applies, then to Loans to which the US Euro-Rate Option applies. Upon
each mandatory prepayment of Term Loans pursuant to this Section 5.5.1, the Term
Loan Commitments automatically shall be permanently and irrevocably reduced by
an amount equal to such prepayment.

                  5.5.2 TERMINATION OF ULTRA ACQUISITION.

                  If the Ultra Acquisition does not close on or before January
31, 1997, or if prior to such date CIH's obligations to proceed to close the
Ultra Acquisition are terminated, then upon the earlier to occur of such events
the CIH Revolving Credit Commitments shall be automatically terminated.

                  5.5.3 QUALIFIED NOTE PLACEMENT.

                  If TEC issues notes pursuant to a Qualified Note Placement,
simultaneously with the closing thereof, the proceeds of such issuance shall be
applied and the Term Loan Commitments shall be reduced in the same manner as set
forth in Section 5.5.1.

                  5.5.4 MANDATORY PREPAYMENTS RESULTING FROM CURRENCY EXCHANGE.

                  If on the last day of an Interest Period or a Bid Loan
Interest Period or the last day of any fiscal quarter of TEC the Dollar
Equivalents of the outstanding CIH Revolving Credit Loans (including any Bank
Guarantee Outstandings) and CIH Bid Loans exceeds the CIH Revolving Credit
Commitments, then CIH shall immediately, without demand or notice, make a
mandatory pre-payment of CIH Revolving Credit Loans and CIH Bid Loans in an
amount sufficient to reduce the outstanding balance of the CIH Revolving Credit
Loans, CIH Bid Loans and Bank Guarantee Outstandings to an amount less than or
equal to the CIH Revolving Credit Commitments.

         5.6 ADDITIONAL COMPENSATION IN CERTAIN CIRCUMSTANCES.

                  5.6.1 INCREASED COSTS OR REDUCED RETURN RESULTING FROM TAXES,
                        RESERVES, CAPITAL ADEQUACY REQUIREMENTS, EXPENSES, ETC.

                  If any Law, guideline or interpretation or any change in any
Law, guideline or interpretation or application thereof by any Official Body
charged with the interpretation or administration thereof or compliance with any
request or directive (whether or not having the force of Law) of any central
bank or other Official Body:

                        (i)   subjects any Bank to any tax or changes the basis
                              of taxation with respect to this Agreement, the
                              Notes, the

                              Loans or payments by the Borrowers of principal,
                              interest, Commitment Fees, or other amounts due
                              from the Borrowers hereunder or under the Notes
                              (except for taxes on the overall net income of
                              such Bank),

                        (ii)  imposes, modifies or deems applicable any reserve,
                              special deposit or similar requirement against
                              credits or commitments to extend credit extended
                              by, or assets (funded or contingent) of, deposits
                              with or for the account of, or other acquisitions
                              of funds by, any Bank, or

                        (iii) imposes, modifies or deems applicable any
                              capital adequacy or similar requirement (A)
                              against assets (funded or contingent) of, or
                              letters of credit, bank guarantees, other credits
                              or commitments to extend credit extended by, any
                              Bank, or (B) otherwise applicable to the
                              obligations of any Bank under this Agreement,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Bank with respect to this Agreement, the Notes or the making, maintenance or
funding of any part of the Loans (or, in the case of any capital adequacy or
similar requirement, to have the effect of reducing the rate of return on any
Bank's capital, taking into consideration such Bank's customary policies with
respect to capital adequacy) by an amount which such Bank in its sole discretion
deems to be material, such Bank shall from time to time notify the applicable
Borrower and the Agent of the amount determined in good faith (using any
averaging and attribution methods employed in good faith, which shall be binding
upon the parties absent manifest error) by such Bank to be necessary to
compensate such Bank for such increase in cost, reduction of income or
additional expense or reduced rates of return. Such notice shall set forth in
reasonable detail the basis for such determination. Such amount shall be due and
payable by the applicable Borrower to such Bank ten (10) Business Days after
such notice is given, subject, however, to the provisions of Section 11.5.3.

                  5.6.2 INDEMNITY.

                  In addition to the compensation required by Section 5.6.1, the
Borrowers shall indemnify each Bank against all liabilities, losses or expenses
(including loss of margin, any loss or expense incurred in liquidating or
employing deposits from third parties and any loss or expense incurred in
connection with funds acquired by a Bank to fund or maintain Loans subject to a
Euro-Rate Option or a Bid Loan Fixed Rate Option) which such Bank sustains or
incurs as a consequence of any

                        (i)   payment, prepayment, conversion or renewal of any
                              Loan to which a Euro-Rate Option or a Bid Loan
                              Fixed Rate Option applies on a day other than the
                              last day of the corresponding Interest Period or
                              Bid Loan Interest Period, 


                                      -56-
<PAGE>   66

                              as applicable (whether or not such payment or
                              prepayment is mandatory, voluntary or automatic
                              and whether or not such payment or prepayment is
                              then due),

                        (ii)  attempt by either Borrower to revoke (expressly,
                              by later inconsistent notices or otherwise) in
                              whole or part any Loan Requests under Section 2.5
                              or any notice relating to prepayments under
                              Section 5.4, or

                        (iii) default by either Borrower in the performance or
                              observance of any covenant or condition contained
                              in this Agreement or any other Loan Document,
                              including any failure of either Borrower to pay
                              when due (by acceleration or otherwise) any
                              principal, interest, Commitment Fee or any other
                              amount due hereunder.

         If any Bank sustains or incurs any such loss or expense, it shall from
time to time notify the applicable Borrower of the amount determined in good
faith by such Bank (which determination may include such assumptions,
allocations of costs and expenses and averaging or attribution methods as such
Bank shall deem reasonable and shall be binding on the parties absent manifest
error) to be necessary to indemnify such Bank for such loss or expense. Such
notice shall set forth in reasonable detail the basis for such determination.
Such amount shall be due and payable by the applicable Borrower to such Bank ten
(10) Business Days after such notice is given.

         5.7 INTERBANK MARKET PRESUMPTION.

         For all purposes of this Agreement and each Note with respect to any
aspects of the Euro-Rate, any Loan under the Euro-Rate Option or any Optional
Currency, each Bank and Agent shall be presumed to have obtained rates, funding,
currencies, deposits, and the like in the applicable interbank market regardless
whether it did so or not; and, each Bank's and Agent's determination of amounts
payable under, and actions required or authorized by, Sections 4.4 and 5.6 shall
be calculated, at each Bank's and Agent's option, as though each Bank and Agent
funded its share of each Borrowing Tranche of Loans under the Euro-Rate Option
through the purchase of deposits of the types and maturities corresponding to
the deposits used as a reference in accordance with the terms hereof in
determining the Euro-Rate applicable to such Loans, whether in fact that is the
case.

         5.8 TAXES.

                  5.8.1 NO DEDUCTIONS.

                  All payments made by each Borrower hereunder and under each
Note shall be made free and clear of and without deduction for any present or
future taxes, levies, imposts, deductions, charges, or withholdings, and all
liabilities with respect thereto, excluding taxes 


                                      -57-
<PAGE>   67

imposed on the net income of any Bank and all income and franchise taxes
applicable to any Bank of the United States or the United Kingdom (all such
non-excluded taxes, levies, imposts, deductions, charges, withholdings, and
liabilities being hereinafter referred to as "TAXES"). If either Borrower shall
be required by Law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note, (i) the sum payable shall be increased as may be
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section) each Bank receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrower shall make such deductions and (iii) the applicable Borrower
shall timely pay the full amount deducted to the relevant tax authority or other
authority in accordance with applicable Law.

                  5.8.2 STAMP TAXES.

                  In addition, each Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges, or
similar levies which arise from any payment made hereunder or from the
execution, delivery, or registration of, or otherwise with respect to, this
Agreement or any Note (hereinafter referred to as "Other Taxes").

                  5.8.3 INDEMNIFICATION FOR TAXES PAID BY A BANK.

                  Each Borrower shall indemnify each Bank for the full amount of
Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section) paid by any
Bank and any liability (including penalties, interest, and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted. This indemnification shall be made within 30 days
from the date a Bank makes written demand therefor.

                  5.8.4 CERTIFICATE.

                  Within 30 days after the date of any payment of any Taxes by
either Borrower, such Borrower shall furnish to each Bank, at its address
referred to herein, the original or a certified copy of a receipt evidencing
payment thereof. If no Taxes are payable in respect of any payment by either
Borrower, such Borrower shall, if so requested by a Bank, provide a certificate
of an officer of such Borrower to that effect.

                  5.8.5 SURVIVAL.

                  Without prejudice to the survival of any other agreement of
Borrowers hereunder, the agreements and obligations of the Borrowers contained
in Sections 5.8.1 through 5.8.4 shall survive the payment in full of principal
and interest hereunder and under any instrument delivered hereunder.

         5.9 JUDGMENT CURRENCY AND OTHER CURRENCY CONVERSIONS.

                  5.9.1 CURRENCY CONVERSION PROCEDURES.

                  If for the purposes of obtaining judgment in any court or
calculating any fee payable under this Agreement it is necessary to convert a
sum due hereunder or under a Note or any other sum in any currency (the
"Original Currency") into another currency (the "Other Currency"), the parties
hereby agree, to the fullest extent permitted by Law, that the rate of exchange
used shall be that at which in accordance with normal banking procedures each
Bank or (as applicable) the Agent (in its capacity as Agent) could purchase the
Original Currency with the Other Currency after any premium and costs of
exchange on the Business Day preceding that on which final judgment is given or
any fee is to be paid.

                  5.9.2 INDEMNITY IN CERTAIN EVENTS.

                  The obligation of the Borrowers in respect of any sum due from
them to any Bank hereunder shall, notwithstanding any judgment in an Other
Currency, whether pursuant to a judgment or otherwise, be discharged only to the
extent that, on the Business Day following receipt by any Bank of any sum
adjudged to be so due in such Other Currency, such Bank may in accordance with
normal banking procedures purchase the Original Currency with such Other
Currency. If the amount of the Original Currency so purchased is less than the
sum originally due to such Bank in the Original Currency, the applicable
Borrower agrees, as a separate obligation and notwithstanding any such judgment
or payment, to indemnify such Bank against such loss.

                       6. REPRESENTATIONS AND WARRANTIES

         6.1 REPRESENTATIONS AND WARRANTIES.

         TEC, as to all matters below, and CIH, as to matters relating to it and
its Subsidiaries, represent and warrant to the Agent and each of the Banks as
follows:

                  6.1.1 ORGANIZATION AND QUALIFICATION.

                  Each Consolidated TEC Group Entity is a corporation or
partnership, duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization. Each Consolidated TEC Group Entity has
the lawful power to own or lease its properties and to engage in the business it
presently conducts or proposes to conduct. Each Consolidated TEC Group Entity is
listed on SCHEDULE 6.1.1 and is duly licensed or qualified and in good standing
in each jurisdiction where the property owned or leased by it or the nature of
the business transacted by it or both makes such licensing or qualification
necessary (except where the failure to be so licensed or qualified would not
constitute a Material Adverse Change), and upon request of the Agent, TEC will
promptly furnish a written list of every jurisdiction where each Consolidated
TEC Group Entity is so qualified.


                                      -59-

                  6.1.2 SUBSIDIARY AND JOINT VENTURE MATTERS.

                  SCHEDULE 6.1.2 (i) sets forth the authorized, issued and
outstanding capital stock of or ownership interest in each Subsidiary and each
Joint Venture and the record owner of such capital stock or other ownership
interest, as the case may be, and (ii) identifies each Subsidiary as a
Restricted Subsidiary or an Unrestricted Subsidiary. Other than as set forth on
SCHEDULE 6.1.2, each of TEC's Subsidiaries is directly or indirectly wholly
owned by TEC and all of the issued and outstanding shares of capital stock of
each such Subsidiary (referred to herein as the "Subsidiary Shares") are owned
free and clear in each case of any Lien and each Joint Venture interest is owned
by a Consolidated TEC Group Entity free and clear of any Lien. All Subsidiary
Shares have been validly issued, and all Subsidiary Shares are fully paid and,
except as otherwise set forth on such SCHEDULE 6.1.2, nonassessable. There are
no options, warrants or other rights outstanding to purchase any Subsidiary
Shares except as indicated on SCHEDULE 6.1.2.

                  6.1.3 POWER AND AUTHORITY.

                  Each Loan Party has full power to enter into, execute, deliver
and carry out this Agreement and the other Loan Documents to which it is a
party, to incur the Indebtedness contemplated by the Loan Documents and to
perform its Obligations under the Loan Documents to which it is a party, and all
such actions have been duly authorized by all necessary proceedings on its part.

                  6.1.4 VALIDITY AND BINDING EFFECT.

                  This Agreement has been duly and validly executed and
delivered by each Borrower and each other Loan Document which any Loan Party is
required to execute and deliver on or after the date hereof will have been duly
executed and delivered by such Loan Party on the required date of delivery of
such Loan Document. This Agreement and each other Loan Document constitutes, or
will constitute, legal, valid and binding obligations of each Loan Party which
is or will be a party thereto on and after its date of delivery thereof,
enforceable against such Loan Party in accordance with its terms, except to the
extent that enforceability of any such Loan Document may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforceability of creditors' rights generally or limiting the
right of specific performance.

                  6.1.5 NO CONFLICT.

                  Neither the execution and delivery of this Agreement or the
other Loan Documents by any Loan Party nor the consummation of the transactions
herein or therein contemplated or compliance with the terms and provisions
hereof or thereof by any of them (i) will conflict with, constitute a default
under or result in any breach of (A) the terms and conditions of the certificate
of incorporation, bylaws or other organizational documents of any Consolidated
TEC Group Entity which is a party thereto or (B) any Law or any agreement or
instrument or order, writ, judgment, injunction or decree to which any such
Consolidated TEC Group Entity is a party, is bound by or is subject, which
conflict, default or breach reasonably 


                                      -60-
<PAGE>   70

would be expected to result in a Material Adverse Change, or (ii) will result in
the creation or enforcement of any Lien whatsoever upon any property (now or
hereafter acquired) of any Consolidated TEC Group Entity (other than Liens
granted under the Loan Documents).

                  6.1.6 LITIGATION.

                  Except as set forth on SCHEDULE 6.1.6, there are no actions,
suits, proceedings or investigations pending or, to the knowledge of any
Consolidated TEC Group Entity, threatened against it at law or equity before any
Official Body which individually or in the aggregate may result in any Material
Adverse Change. No Consolidated TEC Group Entity is in violation of any order,
writ, injunction or any decree of any Official Body which reasonably would be
expected to result in any Material Adverse Change.

                  6.1.7 TITLE TO PROPERTIES.

                  Each Consolidated TEC Group Entity has good and marketable
title to or a valid leasehold interest in all material properties, assets and
other rights which it purports to own or lease or which are reflected as owned
or leased on its books and records, free and clear of all Liens except Permitted
Liens, and subject to the terms and conditions of the applicable leases. All
material leases of property are in full force and effect without the necessity
for any consent which has not previously been obtained upon consummation of the
transactions contemplated hereby.

                        (i)   HISTORICAL STATEMENTS OF TEC. TEC has delivered to

                              TEC Group for TEC's fiscal years 1996, 1997, 1998,
                              1999, 2000, and 2001 and (B) financial projections
                              of the Consolidated TEC Group for TEC's fiscal

                              each case, derived from various assumptions of
                              TEC's management (the "Financial Projections").
                              The Financial Projections reflect the reasonable
                              expectations of TEC's management as of the Closing
                              Date in light of the history of the business,
                              actual costs incurred, present and foreseeable
                              conditions and intentions of TEC's management
                              (excluding the anticipated closing of the Ultra
                              Acquisition), all based on the assumptions
                              thereto, which assumptions were made and based
                              upon information available at the time of
                              preparation of such projections and have been
                              provided to the Agent. The Financial Projections
                              accurately reflect the liabilities of the Combined
                              TEC Group or the Consolidated TEC Group, as the
                              case may be, incurred pursuant to the Loan
                              Documents upon consummation of the transactions
                              contemplated hereby as of the Closing Date; and

                        (iii) ACCURACY OF FINANCIAL STATEMENTS. No Consolidated
                              TEC Group Entity has as of the date of the TEC
                              Historical Statements, any material liabilities,
                              contingent or otherwise, or forward or long-term
                              commitments that are not disclosed in the TEC
                              Historical Statements or in the notes thereto, and
                              except as disclosed therein there are no
                              unrealized or anticipated losses from any
                              commitments of any Consolidated TEC Group Entity
                              which reasonably would be expected to cause a
                              Material Adverse Change.

                  No Combined TEC Group Entity engages or intends to engage
principally, or as one of its important activities, in the business of extending
credit for the purpose, immediately, incidentally or ultimately, of purchasing
or carrying margin stock (within the meaning of Regulation U), other than
purchases by TEC of capital stock of TEC. No part of the proceeds of any Loan
(other than purchases by TEC of capital stock of TEC or to refinance
Indebtedness incurred to do so) or issued Letter of Credit has been or will be
used, immediately, incidentally or ultimately, to purchase or carry any margin
stock or to extend credit to others for the purpose of purchasing or carrying
any margin stock or to refund Indebtedness originally incurred for such
purpose(other than the Term Loans), or for any purpose which entails a violation
of or which is inconsistent with the provisions of the regulations of the Board
of Governors of the Federal Reserve System.

                  6.1.10 FULL DISCLOSURE.

                  Neither this Agreement nor any other Loan Document, nor any
certificate, statement, agreement or other documents furnished to the Agent or
any Bank in connection herewith or therewith, contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements contained herein and therein, in light of the circumstances under
which they were made, not misleading. There is no fact known to any Executive
Officer of any Consolidated TEC Group Entity which materially adversely affects
the business, property, assets, financial condition, results of operations or
prospects of any Consolidated TEC Group Entity which has not been set forth in
this Agreement or in the certificates, statements, agreements or other documents
furnished in writing to the Agent and the Banks prior to or at the date hereof
in connection with the transactions contemplated hereby.

                  6.1.11 TAXES.

                  All federal, state, local and other tax returns required to
have been filed with respect to each Consolidated TEC Group Entity have been
filed, other than those for which the failure to file the same would not
reasonably be expected to result in a Material Adverse Change, and payment or
adequate provision has been made for the payment of all taxes, fees, assessments
and other governmental charges shown to be owing pursuant to said returns or to
assessments received, except to the extent that such taxes, fees, assessments
and other charges are being contested in good faith by appropriate proceedings
diligently conducted and for which such reserves or other appropriate
provisions, if any, as shall be required by GAAP shall have been made. Except
with respect to the Federal income tax return for the Consolidated TEC Group for
the fiscal year ended October 31, 1993, there are no agreements or waivers

tax return of any Consolidated TEC Group Entity for any period.

exists now or will exist after giving effect to and as a result of the
extensions of credit to be made on the Closing Date under the Loan Documents
which constitutes an Event of Default or Potential Default. No Consolidated TEC
Group Entity is in violation of (i) any term of its certificate of
incorporation, bylaws, or other organizational documents or (ii) any material
agreement or instrument to which it is a party or by which it or any of its
properties may be subject or bound where such violation would constitute a
Material Adverse Change.

                  6.1.14 PATENTS, TRADEMARKS, COPYRIGHTS, LICENSES, ETC.

                  Each Consolidated TEC Group Entity owns or possesses all the

properties and to carry on its business as presently conducted and planned to be
conducted by the Consolidated TEC Group taken as a whole, without known conflict

                  TEC has delivered to the Agent a true and correct listing of
the property and general liability insurance of the Consolidated TEC Group. No
notice has been given or claim made and to the best knowledge of the Executive
Officers and the individual responsible for insurance matters of the
Consolidated TEC Group Entities no grounds exist to cancel or avoid any of such
policies or bonds or to reduce the coverage provided thereby. Such policies and
bonds provide adequate coverage from reputable and financially sound insurers in
amounts sufficient to insure the assets and risks of each Consolidated TEC Group
Entity in accordance with prudent business practice in the industry of the
Consolidated TEC Group.

                  6.1.16 COMPLIANCE WITH LAWS.

                  The Consolidated TEC Group Entities are in compliance in all
material respects with all applicable Laws (other than Environmental Laws which
are specifically addressed in Section 6.1.21) in all jurisdictions in which any
Consolidated TEC Group Entity is presently or currently anticipates it will be
doing business except where the failure to do so would not constitute a Material
Adverse Change.

                              other member of the ERISA Group. TEC and all other
                              members of the ERISA Group have made when due any

                              thereto. With respect to each Plan and
                              Multiemployer Plan, TEC and each other member of
                              the ERISA Group (i) have fulfilled in all material

                              Plan, and no amendment with respect to which
                              security is required under Section 307 of ERISA

                              disclosed in, and as of the date of, the most
                              recent actuarial report for each such Plan, does
                              not exceed the aggregate fair market value of the

                              to be reorganized or terminated, within the
                              meaning of Title IV of ERISA;

                        (vii) To the extent that any Benefit Arrangement is

Laws including those related to equal employment opportunity and affirmative
action, labor relations, minimum wage, overtime, child labor, medical insurance
continuation, worker adjustment and relocation notices, immigration controls and
worker and unemployment compensation, where the failure to comply reasonably
would be expected to constitute a Material Adverse Change. There are no
outstanding grievances, arbitration awards or appeals therefrom arising out of
the Labor Contracts or current or threatened strikes, picketing, handbilling or
other work stoppages or slowdowns at facilities of any Consolidated TEC Group
Entity which in any case would constitute a Material Adverse Change.

                              acquirer of any Property from any Consolidated TEC

                              Environmental Conditions which reasonably would be
                              expected to result in a Material Adverse Change,

                  8.1.2 PAYMENT OF LIABILITIES, INCLUDING TAXES, ETC.

                  Each Borrower shall, and shall cause each other Consolidated
TEC Group Entity to, duly pay and discharge all liabilities to which it is
subject or which are asserted against it, promptly as and when the same shall
become due and payable, including all taxes, assessments and governmental
charges upon it or any of its properties, assets, income or profits, prior to

liabilities, including taxes, assessments or charges, are being contested in
good faith and by appropriate and lawful proceedings diligently conducted and
for which such reserve or other appropriate provisions, if any, as shall be

Group will pay all such liabilities forthwith upon the commencement of
proceedings to foreclose any Lien which may have attached as security therefor
unless and as long as such proceedings are stayed.

fire and such other insurable hazards as such assets are commonly insured
(including fire, extended coverage, property damage, workers' compensation,
public liability and business interruption insurance) and against other risks
(including errors and omissions with respect to directors and officers) in such
amounts as similar properties and assets are insured by prudent companies in
similar circumstances carrying on similar businesses, and with reputable and
financially sound insurers, including self-insurance to the extent customary,
for each such Consolidated TEC Group Entity within its respective industry. At
the request of the Agent, the Borrowers shall deliver to the Agent on the

TEC Group Entity to, maintain in full force and effect all patents, trademarks,

the Banks to visit and inspect any of its properties and to examine and make
excerpts from its books and records and discuss its business affairs, finances
and accounts with its Authorized Officers, all in such detail as any of the
Banks may reasonably request, PROVIDED that each Bank shall provide the Borrower
and the Agent with reasonable notice prior to any visit or inspection, the Banks
shall attempt to reasonably coordinate such requests and all information
obtained by any Bank shall be subject to Section 11.12.

                  8.1.7 KEEPING OF RECORDS AND BOOKS OF ACCOUNT.

                  Each Borrower shall, and shall cause each other Consolidated
TEC Group Entity to, maintain and keep proper books and records which will
enable the Consolidated TEC Group to issue consolidated and consolidating
financial statements and the Combined TEC Group to issue combined financial
statements, in each case in accordance with GAAP and as otherwise required by
applicable Laws of any Official Body having jurisdiction over any Consolidated
TEC Group Entity, and in which full, true and correct entries shall be made in

                              Executive Officer of TEC certifying as to
                              compliance with the foregoing clauses (A), (B) and
                              (C) above.

      As of the end of each fiscal year of TEC, it shall be determined whether
during such year the Combined TEC Group received Consideration aggregating in
excess of $5,000,000 with respect to transactions occurring during such year
under clauses (iv), (v) and (vii) above (such amount, if any, in excess of
$5,000,000 being herein called the "Excess Consideration"). If so, and if as of
the end of such fiscal year of TEC, the Combined TEC Group in the aggregate has
not made Qualified Investments during such fiscal year in an amount equal to the
Excess Consideration received during such fiscal year, then, subject to the
provisions of the final sentence of this paragraph, TEC shall make a mandatory
prepayment of the Term Loans pursuant to Section 5.5.1 in an amount equal to 75%
of the amount by which such Excess Consideration received during such fiscal
year exceeds such Qualified Investments made during such fiscal year. As used in
the foregoing sentence, "Qualified Investments" for any fiscal year period of
determination means the sum (determined in each case for the Combined TEC Group
in the aggregate during the relevant fiscal year) of the following: (i) capital
expenditures in excess of $9,000,000 made by any Combined TEC Group Entity
during such fiscal year, PLUS (ii) Acquisitions permitted pursuant to Section
8.2.5(vi) and made during such fiscal year. Notwithstanding anything contained
herein to the contrary, if any transaction described in clause (iv) shall be
consummated, TEC shall not be required to make a prepayment of the Term Loans
with any Excess Consideration which is attributable to such transaction until
six (6) months have elapsed since the closing thereof, and any Qualified
Investments made during such six (6) month period shall be deemed to be made
with the proceeds of such transaction.

                  8.2.7 AFFILIATE TRANSACTIONS.

                  Except as set forth on SCHEDULE 8.2.7 each of the Borrowers
shall not, and shall not permit any Consolidated TEC Group Entity to, enter into
or carry out any transaction with any of its Affiliates (including purchasing
property or services from or selling property or 


                                      -87-

otherwise prohibited by this Agreement and, is entered into in the ordinary
course of business upon fair and reasonable arm's-length terms and conditions or
is approved by the applicable Borrower's independent Board of Directors or an
appropriate committee thereof as being upon fair and reasonable arm's length
terms and conditions (including without limitation employment arrangements with
any Executive Officer of a Consolidated TEC Group Entity), all of which are
fully disclosed to the Agent and the Banks and are in accordance with all
applicable Law.

                  8.2.8 GUARANTIES BY MATERIAL DOMESTIC SUBSIDIARIES.

                  Each Borrower shall not, and shall not permit any of its
Subsidiaries to, own or create directly or indirectly any Material Domestic
Subsidiary which has not joined the Master Guarantee Agreement as a Guarantor
and executed the Master Intercompany Subordination Agreement.

                  8.2.9 CONTINUATION OF OR CHANGE IN BUSINESS.

                  Each Borrower shall not, and shall not permit any other
Consolidated TEC Group Entity to, engage in any line of business other than
substantially those lines of businesses as conducted and operated by the
Consolidated TEC Group on the Closing Date and those businesses reasonably

                              circumstances or set of circumstances resulting in
                              liability under ERISA, would constitute a Material

                              Multiple Employer Plan, where any such withdrawal
                              would result in a material liability of TEC or any
                              member of the ERISA Group;

                        (vii) terminate, or institute proceedings to terminate,

                              such failure would result in a Material Adverse
                              Change.

Documents or any action taken or omitted by the Agent hereunder or thereunder,
PROVIDED that the Borrowers shall not be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements (A) if the same results from the Agent's gross
negligence or willful misconduct, or (B) if the applicable Borrower was not
given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense (except that such Borrower shall remain liable
to the extent such failure to give notice does not result in a loss to 


                                     -103-
<PAGE>   113

such Borrower), or (C) if the same results from a compromise or settlement
agreement entered into without the consent of the applicable Borrower, which
shall not be unreasonably withheld. In addition, the Borrowers agree to
reimburse and pay all reasonable out-of-pocket expenses of the Agent's regular
employees and agents engaged to perform audits of the books, records and
properties of the Consolidated TEC Group. Notwithstanding the foregoing, CIH's
liability for the foregoing shall be limited to a PRO RATA share based on the
Commitments.

         10.6 EXCULPATORY PROVISIONS.

         None of the Agent or any of its respective directors, officers,
employees, agents, attorneys or Affiliates shall (a) be liable to any Bank for
any action taken or omitted to be taken by it or them hereunder, or in
connection herewith including pursuant to any Loan Document, unless caused by
its or its respective directors, officers, employees, agents, attorneys or
Affiliates own gross negligence or willful misconduct, (b) be responsible in any
manner to any of the Banks for the effectiveness, enforceability, genuineness,
validity or due execution of this Agreement or any other Loan Documents or for
any recital, representation, warranty, document, certificate, report or
statement herein or made or furnished under or in connection with this Agreement
or any other Loan Documents, or (c) be under any obligation to any of the Banks
to ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions hereof or thereof on the part of the Loan
Parties, or the financial condition of the Loan Parties, or the existence or
possible existence of any Event of Default or Potential Default. None of the
Agent or any Bank or any of their respective directors, officers, employees,
agents, attorneys or Affiliates shall be liable to any of the Loan Parties for
any consequential, special or indirect damages, losses or expenses (including
without limitation, counsel fees) resulting from any breach of contract, tort or
other wrong in connection with the negotiation, documentation, administration or
collection of the Loans or any of the Loan Documents.

         10.7 REIMBURSEMENT AND INDEMNIFICATION BY BANKS OF THE AGENT.

         Each Bank agrees to reimburse and indemnify the Agent (to the extent
not reimbursed by the Borrowers and without limiting the Obligation of the
Borrowers to do so) in proportion to its Ratable Share from and against all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in its capacity as such or
in its capacity of issuing Letters of Credit or Bank Guarantees, in any way
relating to or arising out of this Agreement or any other Loan Documents or any
action taken or omitted by the Agent hereunder or thereunder, PROVIDED that no
Bank shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
(a) if the same results from the Agent's gross negligence or willful misconduct,
or (b) if such Bank was not given notice of the subject claim and the
opportunity to participate in the defense thereof, at its expense (except that
such Bank shall remain liable to the extent such failure to give notice does not
result in a loss to the Bank), or (c) if the same results from a compromise and
settlement agreement entered into without the consent of such Bank, which shall
not be unreasonably withheld. In addition, each Bank agrees promptly upon demand
to 


                                     -104-
<PAGE>   114

reimburse the Agent (to the extent not reimbursed by the Borrowers and
without limiting the Obligation of the Borrowers to do so) in proportion to its
Ratable Share for all amounts due and payable by the Borrowers to the Agent in
connection with the Agent's periodic audit of the Loan Parties' books, records
and business properties.

         10.8 RELIANCE BY AGENT.

         The Agent shall be entitled to rely upon any writing, telegram, telex
or teletype message, resolution, notice, consent, certificate, letter,
cablegram, statement, order or other document or conversation by telephone or
otherwise believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons, and upon the advice and opinions of
counsel and other professional advisers selected by the Agent. The Agent shall
be fully justified in failing or refusing to take any action hereunder unless it
shall first be indemnified to its satisfaction by the Banks against any and all
liability and expense (other than a liability or expense relating to gross
negligence or willful misconduct) which may be incurred by it by reason of
taking or continuing to take any such action.

         10.9 NOTICE OF DEFAULT.

         The Agent shall not be deemed to have knowledge or notice of the
occurrence of any Potential Default or Event of Default unless the Agent has
received written notice from a Bank or the Borrowers referring to this
Agreement, describing such Potential Default or Event of Default and stating
that such notice is a "notice of default."

         10.10 NOTICES.

         The Agent shall promptly send to each Bank a copy of all notices and
other documents received from the Borrowers pursuant to the provisions of this
Agreement or the other Loan Documents promptly upon receipt thereof. The Agent
shall promptly notify the Borrowers and the other Banks of each change in the
Base Rate and the effective date thereof.

         10.11 BANKS IN THEIR INDIVIDUAL CAPACITIES.

         With respect to the Commitments and the Loans made by it, the Agent
shall have the same rights and powers hereunder as any other Bank and may
exercise the same as though it were not the Agent, and the term "Banks" shall,
unless the context otherwise indicates, include the Agent in its individual
capacity. The Agent and its Affiliates and each of the Banks and their
respective Affiliates may, without liability to account, except as prohibited
herein, make loans to, accept deposits from, discount drafts for, act as trustee
under indentures of, and generally engage in any kind of banking or trust
business with, the Consolidated TEC Group and their Affiliates, in the case of
the Agent, as though it were not acting as Agent hereunder and in the case of
each Bank, as though such Bank were not a Bank hereunder.


                                     -105-
<PAGE>   115

         10.12 HOLDERS OF NOTES.

         The Agent may deem and treat any payee of any Note as the owner thereof
for all purposes hereof unless and until written notice of the assignment or
transfer thereof shall have been filed with the Agent. Any request, authority or
consent of any Person who at the time of making such request or giving such
authority or consent is the holder of any Note shall be conclusive and binding
on any subsequent holder, transferee or assignee of such Note or of any Note or
Notes issued in exchange therefor.

         10.13 EQUALIZATION OF BANKS.

         The Banks and the holders of any participations in any Notes agree
among themselves that, with respect to all amounts received by any Bank or any
such holder for application on any Obligation hereunder or under any Note or
under any such participation, whether received by voluntary payment, by
realization upon security, by the exercise of the right of set-off or banker's
lien, by counterclaim or by any other non-pro rata source, equitable adjustment
will be made in the manner stated in the following sentence so that, in effect,
all such excess amounts will be shared ratably among the Banks and such holders
in proportion to their interests in payments under the Notes, except as
otherwise provided in Sections 4.4.2 or 5.6.1. The Banks or any such holder
receiving any such amount shall purchase for cash from each of the other Banks
an interest in such Bank's Loans in such amount as shall result in a ratable
participation by the Banks and each such holder in the aggregate unpaid amount
under the Notes, PROVIDED that if all or any portion of such excess amount is
thereafter recovered from the Bank or the holder making such purchase, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, together with interest or other amounts, if any, required by law
(including court order) to be paid by the Bank or the holder making such
purchase.

         10.14 SUCCESSOR AGENT.

         The Agent (i) may resign as Agent or (ii) shall resign if such
resignation is requested by the Required Banks (if the Agent is a Bank, the
Agent's Loans and its Commitment shall be considered in determining whether the
Required Banks have requested such resignation), in either case of (i) or (ii)
by giving not less than thirty (30) days' prior written notice to the Borrowers.
If the Agent shall resign under this Agreement, then subject to the consent of
the Borrowers (which consent shall not be unreasonably withheld and which
consent shall not be required during any period in which an Event of Default
exists) either (a) the Required Banks shall appoint from among the Banks a
successor agent for the Banks, or (b) if a successor agent shall not be so
appointed and approved within the thirty (30) day period following the Agent's
notice to the Banks of its resignation, then the Agent shall appoint a successor
agent who shall serve as Agent until such time as the Required Banks appoint a
successor agent. Upon its appointment, such successor agent shall succeed to the
rights, powers and duties of the Agent and the term "Agent" shall mean such
successor effective upon its appointment, and the former Agent's rights, powers
and duties as Agent shall be terminated without any other or further act or deed
on the part of such former Agent or any of the parties to this Agreement. After
the 


                                     -106-
<PAGE>   116

resignation of any Agent hereunder, the provisions of this Article 10 shall
inure to the benefit of such former Agent and such former Agent shall not by
reason of such resignation be deemed to be released from liability for any
actions taken or not taken by it while it was an Agent under this Agreement.
Notwithstanding anything herein to the contrary, any successor Agent must have a
London lending office so long as the CIH Revolving Credit Commitments, any Bank
Gurarantees or any CIH Bid Loans remain outstanding or in effect.

         10.15 OTHER FEES.

         The Borrowers shall pay to the Agent the fees, including in the case of
TEC a non-refundable fee (the "Bid Loan Processing Fee") in connection with each
processing of a Bid Loan Request (collectively the "Agent's Fees") due pursuant
to that certain commitment letter and related fee letter, each dated October 15,
1996 at the times and in the amounts set forth in such letters.

         10.16 AVAILABILITY OF FUNDS.

         Unless the Agent shall have been notified by a Bank prior to the date
upon which a Loan is to be made that such Bank does not intend to make available
to the Agent such Bank's portion of such Loan, the Agent may assume that such
Bank has made or will make such proceeds available to the Agent on such date and
the Agent may, in reliance upon such assumption (but shall not be required to),
make available to the Borrowers a corresponding amount. If such corresponding
amount is not in fact made available to the Agent by such Bank, the Agent shall
be entitled to recover such amount on demand from such Bank (or, if such Bank
fails to pay such amount forthwith upon such demand, from the Borrowers)
together with interest thereon, in respect of each day during the period
commencing on the date such amount was made available to the Borrowers and
ending on the date the Agent recovers such amount, at a rate per annum equal to
the Federal Funds Effective Rate.

         10.17 CALCULATIONS.

         In the absence of gross negligence or willful misconduct, the Agent
shall not be liable for any error in computing the amount payable to any Bank
whether in respect of the Loans, fees or any other amounts due to the Banks
under this Agreement. In the event an error in computing any amount payable to
any Bank is made, the Agent, the Borrowers and each affected Bank shall,
forthwith upon discovery of such error, make such adjustments as shall be
required to correct such error, and any compensation therefor will be calculated
at the Federal Funds Effective Rate.

         10.18 BENEFICIARIES.

         Except as expressly provided herein, the provisions of this Article 10
are solely for the benefit of the Agent and the Banks, and the Loan Parties
shall not have any rights to rely on or enforce any of the provisions hereof. In
performing its functions and duties under this Agreement, the Agent shall act
solely as agent of the Banks and does not assume and shall not be 


                                     -107-
<PAGE>   117

deemed to have assumed any obligation toward or relationship of agency or trust
with or for any of the Loan Parties.

                               11. MISCELLANEOUS

         11.1 MODIFICATIONS, AMENDMENTS OR WAIVERS.

         With the written consent of the Required Banks, the Agent, acting on
behalf of all the Banks, and the Borrowers, on behalf of the Loan Parties, may
from time to time enter into written agreements amending or changing any
provision of this Agreement or any other Loan Document or the rights of the
Banks or the Loan Parties hereunder or thereunder, or may grant written waivers
or consents to a departure from the due performance of the Obligations of the
Loan Parties hereunder or thereunder; provided, however, that the written
consent of the Required Banks shall not be required with respect to the joinder
of additional Loan Parties pursuant to Section 11.18. Any such agreement, waiver
or consent made with such written consent shall be effective to bind all the
Banks and the Loan Parties; PROVIDED, that, without the written consent of all
the Banks, no such agreement, waiver or consent may be made which will:

                  11.1.1 INCREASE OF COMMITMENTS; EXTENSION OF EXPIRATION DATE.

                  Increase the amount of the Commitment of any Bank hereunder or
extend the Expiration Date;

                  11.1.2 EXTENSION OF PAYMENT; REDUCTION OF PRINCIPAL, INTEREST
                         OR FEES; MODIFICATION OF TERMS OF PAYMENT.

                  Whether or not any Loans are outstanding, extend the time for
payment of principal or interest of any Loan, the Commitment Fee or any other
fee payable to any Bank, or reduce the principal amount of or the rate of
interest borne by any Loan or reduce the Commitment Fee or any other fee payable
to any Bank, or otherwise affect the terms of payment of the principal of or
interest of any Loan, the Commitment Fee or any other fee payable to any Bank;

                  11.1.3 RELEASE OF GUARANTOR.

                  Release any Material Domestic Subsidiary from its Obligations
under the Master Guarantee Agreement; or

                  11.1.4 MISCELLANEOUS.

                  Amend Sections 5.2 [Pro Rata Treatment of Banks], 10.6
[Exculpatory Provisions] or 10.13 [Equalization of Banks] or this Section 11.1,
alter any provision regarding the pro rata treatment of the Banks, change the
definition of Required Banks, or change any requirement providing for the Banks
or the Required Banks to authorize the taking of any action hereunder.


                                     -108-
<PAGE>   118

                  No agreement, waiver or consent which would modify the
interests, rights or obligations of the Agent in its capacity as Agent, or its
capacity as the issuer of Letters of Credit shall be effective without the
written consent of the Agent.

         11.2 NO IMPLIED WAIVERS; CUMULATIVE REMEDIES; WRITING REQUIRED.

         No course of dealing and no delay or failure of the Agent or any Bank
in exercising any right, power, remedy or privilege under this Agreement or any
other Loan Document shall affect any other or future exercise thereof or operate
as a waiver thereof, nor shall any single or partial exercise thereof or any
abandonment or discontinuance of steps to enforce such a right, power, remedy or
privilege preclude any further exercise thereof or of any other right, power,
remedy or privilege. The rights and remedies of the Agent and the Banks under
this Agreement and any other Loan Documents are cumulative and not exclusive of
any rights or remedies which they would otherwise have. Any waiver, permit,
consent or approval of any kind or character on the part of any Bank of any
breach or default under this Agreement or any such waiver of any provision or
condition of this Agreement must be in writing and shall be effective only to
the extent specifically set forth in such writing.

         11.3 REIMBURSEMENT AND INDEMNIFICATION OF BANKS BY THE BORROWERS;
              TAXES.

         The Borrowers agree unconditionally upon demand to pay or reimburse to
each Bank and to save each Bank harmless against (i) liability for the payment
of all reasonable out-of-pocket costs, expenses and disbursements (including
fees and expenses of counsel for each Bank except with respect to (A), (B) and
(C) below), incurred by such Bank (a) in connection with the administration and
interpretation of this Agreement, the other Loan Documents, and the other
instruments and documents to be delivered hereunder, provided such reimbursement
with respect to administration only shall be available to such Bank at a time
when an Event of Default shall have occurred and be continuing, (b) relating to
any amendments, waivers or consents pursuant to provisions hereof, (c) in
connection with the enforcement of this Agreement or any other Loan Document, or
collection of amounts due hereunder or thereunder or the proof and allowability
of any claim arising under this Agreement or any other Loan Document, whether in
bankruptcy or receivership proceedings or otherwise, and (d) in any workout,
restructuring or in connection with the protection, preservation, exercise or
enforcement of any of the terms hereof or of any rights hereunder or under any
other Loan Document or in connection with any foreclosure, collection or
bankruptcy proceedings; (ii) all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses and disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted by or
asserted against such Bank as a result of the use of the proceeds of the Loans;
and (iii) all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against such Bank,
in its capacity as such, in any way relating to or arising out of this Agreement
or any other Loan Documents or any action taken or omitted by such Bank
hereunder or thereunder, PROVIDED that the Borrowers shall not be liable for any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements (A) if the same results from


                                     -109-
<PAGE>   119

such Bank's gross negligence or willful misconduct, or (B) if a Borrower was not
given notice of the subject claim and the opportunity to participate in the
defense thereof, at its expense (except that such Borrower shall remain liable
to the extent such failure to give notice does not result in a loss to such
Borrower), or (C) if the same results from a compromise or settlement agreement
entered into without the consent of the applicable Borrower, which shall not be
unreasonably withheld. The Banks will attempt to minimize the fees and expenses
of legal counsel for the Banks which are subject to reimbursement by the
applicable Borrower hereunder by considering the usage of one law firm to
represent the Banks and the Agent if appropriate under the circumstances. The
Borrowers agree unconditionally to pay all stamp, document, transfer, recording
or filing taxes or fees and similar impositions now or hereafter determined by
the Agent or any Bank to be payable in connection with this Agreement or any
other Loan Document, and the Borrowers agree unconditionally to save the Agent
and the Banks harmless from and against any and all present or future claims,
liabilities or losses with respect to or resulting from any omission to pay or
delay in paying any such taxes, fees or impositions, except as provided
otherwise above.

         11.4 HOLIDAYS.

         Whenever any payment or action to be made or taken hereunder shall be
stated to be due on a day which is not a Business Day, such payment or action
shall be made or taken on the next following Business Day (except as provided in
Section 4.2.1 with respect to Interest Periods under a Euro-Rate Option), and
such extension of time shall be included in computing interest or fees, if any,
in connection with such payment or action.

         11.5 FUNDING BY BRANCH, SUBSIDIARY OR AFFILIATE.

                  11.5.1 NOTIONAL FUNDING.

                  Each Bank shall have the right from time to time, without
notice to the Borrowers, to deem any branch, Subsidiary or Affiliate (which for
the purposes of this Section 11.5 shall mean any corporation or association
which is directly or indirectly controlled by or is under direct or indirect
common control with any corporation or association which directly or indirectly
controls such Bank) of such Bank to have made, maintained or funded any Loan to
which a Euro-Rate Option applies at any time, PROVIDED that immediately
following (on the assumption that a payment were then due from the applicable
Borrower to such other office), and as a result of such change, the applicable
Borrower would not be under any greater financial obligation pursuant to Section
5.6 than it would have been in the absence of such change. Notional funding
offices may be selected by each Bank without regard to such Bank's actual
methods of making, maintaining or funding the Loans or any sources of funding
actually used by or available to such Bank.

                  11.5.2 ACTUAL FUNDING.

                  Each Bank shall have the right from time to time to make or
maintain any Loan by arranging for a branch, Subsidiary or Affiliate of such
Bank to make or maintain such 


                                     -110-
<PAGE>   120

Loan subject to the last sentence of this Section 11.5.2. If any Bank causes a
branch, Subsidiary or Affiliate to make or maintain any part of the Loans
hereunder, all terms and conditions of this Agreement shall, except where the
context clearly requires otherwise, be applicable to such part of the Loans to
the same extent as if such Loans were made or maintained by such Bank, but in no
event shall any Bank's use of such a branch, Subsidiary or Affiliate to make or
maintain any part of the Loans hereunder cause such Bank or such branch,
Subsidiary or Affiliate to incur any cost or expenses payable by the applicable
Borrower hereunder or require the applicable Borrower to pay any other
compensation to any Bank (including any expenses incurred or payable pursuant to
Section 5.6) which would otherwise not be incurred.

                  11.5.3 CHANGES TO OTHER BRANCHES, SUBSIDIARIES OR AFFILIATES.

                  If a Bank claims any additional amounts payable pursuant to
Section 5.6 or that it is unable to make Loans to which a Euro-Rate Option
applies, it shall use its reasonable efforts (consistent with legal and
regulatory restrictions) to avoid the need for paying such additional amounts or
such inability, including changing the jurisdiction of its applicable lending
office or moving the Loan to a Subsidiary or Affiliate; provided, however, that
the taking of any such action would not, in the reasonable judgment of such
Bank, be disadvantageous to such Bank.

         11.6 NOTICES.

         All notices, requests, demands, directions and other communications (as
used in this Section 11.6, collectively referred to as "notices") given to or
made upon any party hereto under the provisions of this Agreement shall be by
telephone or in writing (including telex or facsimile communication) unless
otherwise expressly permitted hereunder and shall be delivered or sent by telex
or facsimile to the respective parties at the addresses and numbers set forth
under their respective names on the signature pages hereof or in accordance with
any subsequent unrevoked written direction from any party to the others. All
notices shall, except as otherwise expressly herein provided, be effective (a)
in the case of telex or facsimile, when received, (b) in the case of
hand-delivered notice, when hand-delivered, (c) in the case of telephone, when
telephoned, PROVIDED, however, that in order to be effective, telephonic notices
must be confirmed in writing no later than the next day by letter, facsimile or
telex, (d) if given by mail, four (4) days after such communication is deposited
in the mail with first-class postage prepaid, return receipt requested, and (e)
if given by any other means (including by air courier), when delivered;
PROVIDED, that notices to the Agent shall not be effective until received. Any
Bank giving any notice to any Loan Party shall simultaneously send a copy
thereof to the Agent, and the Agent shall promptly notify the other Banks of the
receipt by it of any such notice.

         11.7 SEVERABILITY.

         The provisions of this Agreement are intended to be severable. If any
provision of this Agreement shall be held invalid or unenforceable in whole or
in part in any jurisdiction, such provision shall, as to such jurisdiction, be
ineffective to the extent of such invalidity or 


                                     -111-
<PAGE>   121

unenforceability without in any manner affecting the validity or enforceability
thereof in any other jurisdiction or the remaining provisions hereof in any
jurisdiction.

         11.8 GOVERNING LAW.

         Each Letter of Credit and Section 2.9 shall be subject to the Uniform
Customs and Practice for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No. 500, as the same may be revised or amended
from time to time, and to the extent not inconsistent therewith, the internal
laws of the Commonwealth of Pennsylvania without regard to its conflict of laws
principles and the balance of this Agreement shall be deemed to be a contract
under the Laws of the Commonwealth of Pennsylvania and for all purposes shall be
governed by and construed and enforced in accordance with the internal laws of
the Commonwealth of Pennsylvania without regard to its conflict of laws
principles. Each Bank Guarantee shall be governed by English Law and subject to
the non-exclusive jurisdiction of the English Courts.

         11.9 PRIOR UNDERSTANDING.

         This Agreement and the other documents and instruments executed in
connection herewith supersede all prior understandings and agreements, whether
written or oral, between the parties hereto and thereto relating to the
transactions provided for herein and therein, including any prior
confidentiality agreements and commitments except that the Borrowers' fee
payment obligations contained in the fee letter referred to in Section 10.15
shall continue in full force and effect.

         11.10 DURATION; SURVIVAL.

         All representations and warranties of the Borrowers contained herein or
made in connection herewith shall survive the making of Loans and issuance of
Letters of Credit and shall not be waived by the execution and delivery of this
Agreement, any investigation by the Agent or the Banks, the making of Loans,
issuance of Letters of Credit, or payment in full of the Loans. All covenants
and agreements of the Borrowers contained in Sections 8.1, 8.2 and 8.3 shall
continue in full force and effect from and after the date hereof so long as the
Borrowers may borrow or request Letters of Credit and Bank Guarantees hereunder
and until termination of the Commitments, repayment of all Loans and expiration
or termination of all Letters of Credit and Bank Guarantees. All covenants and
agreements of the Borrowers contained herein relating to the payment of
principal, interest, premiums, additional compensation or expenses and
indemnification, including those set forth in the Notes, Article 5 and Sections
10.5, 10.7 and 11.3, shall survive payment in full of the Loans, expiration or
termination of the Letters of Credit and Bank Guarantees and termination of the
Commitments.

         11.11 SUCCESSORS AND ASSIGNS.

         This Agreement shall be binding upon and shall inure to the benefit of
the Banks, the Agent, the Loan Parties and their respective successors and
assigns, except that, other than as 


                                     -112-
<PAGE>   122

contemplated by Sections 8.2.5 and 8.2.6, none of the Loan Parties may assign or
transfer any of its rights and Obligations hereunder or any interest herein
without consent of all Banks. Each Bank may, at its own cost, make assignments
of or sell participations in all or any part of its Commitment and Loans and its
Revolving Credit Ratable Share of Letter of Credit/Guarantee Outstandings to one
or more banks or other entities, subject to the consent of the Borrowers (which
consent shall not be required during any period in which an Event of Default
exists) and the Agent with respect to any assignee, such consents not to be
unreasonably withheld, and PROVIDED that (i) assignments may not be made in
amounts less than $5,000,000 and (ii) after giving effect to any such
assignment, no Bank which remains a Bank thereafter shall have Commitments of
less than $10,000,000. In the case of an assignment, upon receipt by the Agent
of the Syndication Assignment and Assumption Agreement with respect to all
assignments made as part of the initial syndication of the credit facilities
under this Agreement after the Closing Date, or the Assignment and Assumption
Agreement with respect to each subsequent assignment, the assignee or assignees
shall have, to the extent of such assignment (unless otherwise provided
therein), the same rights, benefits and obligations as it would have if it had
been a signatory Bank hereunder, the Commitments in Section 2.1 shall be
adjusted accordingly and Schedule 1.1(B) to this Agreement shall be modified by
Schedule I to the Syndication Assignment and Assumption Agreement with respect
to all assignments made as part of the initial syndication of the credit
facilities under this Agreement after the Closing Date or by Schedule I to each
Assignment and Assumption Agreement with respect to subsequent assignments, and
upon surrender of any Notes subject to such assignment, the Borrower shall
execute and deliver new Notes to the assignee in an amount equal to the amount
of the Commitments assumed by it and new Notes to the assigning Bank in an
amount equal to the Commitments retained by it hereunder. Any assigning Bank
shall pay to the Agent a service fee in the amount of $3,500 for each
assignment, which amount shall not be subject to reimbursement or
indemnification by the Borrowers. In the case of a participation, the
participant shall only have the rights specified in Section 9.2.3 (the
participant's rights against such Bank in respect of such participation to be
those set forth in the agreement executed by such Bank in favor of the
participant relating thereto and not to include any voting rights), all of such
Bank's obligations under this Agreement or any other Loan Document shall remain
unchanged, and all amounts payable by any Loan Party hereunder or thereunder
shall be determined as if such Bank had not sold such participation. Any
assignee or participant which is not incorporated under the Laws of the United
States of America or a state thereof shall deliver to the Borrowers and the
Agent (i) the form of certificate described in Section 11.17 relating to federal
income tax withholding, and (ii) if the assignment or participation includes an
interest in the Revolving Credit Commitments, the form of certificate described
in Section 11.17 relating to taxes in the United Kingdom. Each Bank may furnish
any publicly available information concerning any Consolidated TEC Group Entity
and any other information concerning any Consolidated TEC Group Entity in the
possession of such Bank from time to time to assignees and participants
(including prospective assignees or participants), PROVIDED that such assignees
and participants agree to be bound by the provisions of Section 11.12.
Notwithstanding any other language in this Agreement, any Bank may at any time
assign all or any portion of its rights under this 


                                     -113-

Agreement and its Notes to a Federal Reserve Bank as collateral in accordance
with Regulation A and the applicable Operating Circular of such Federal Reserve
Bank.

         11.12 CONFIDENTIALITY.

         The Agent and the Banks each agree to keep confidential all information
obtained from any Consolidated TEC Group Entity which is nonpublic and
confidential or proprietary in nature (including any information either Borrower
specifically designates as confidential), except as provided below, and to use
such information only in connection with their respective capacities under this
Agreement and for the purposes contemplated hereby. The Agent and the Banks
shall be permitted to disclose such information (i) to outside legal counsel,
accountants and other professional advisors who need to know such information in
connection with the administration and enforcement of this Agreement and who are
notified that the information is to be treated as confidential, (ii) to
assignees and participants as contemplated by Section 11.11, (iii) to the extent
requested by any bank regulatory authority or, with notice to the applicable
Borrower if not prohibited, as otherwise required by applicable Law or by any
subpoena or similar legal process, or in connection with any investigation or
proceeding arising out of the transactions contemplated by this Agreement, (iv)
if it becomes publicly available other than as a result of a breach of this
Agreement or becomes available from a source not known to be subject to
confidentiality restrictions, (v) if the applicable Borrower shall have
consented to such disclosure, or (vi) after notice to the applicable Borrower
unless such Borrower is an adverse party in such litigation, in connection with
any litigation to which any Bank is a party the subject matter of which involves
this Agreement or is deemed necessary upon the advice of legal counsel of such
Bank by such Bank in any defense of such litigation.

         11.13 COUNTERPARTS.

         This Agreement may be executed by different parties hereto on any
number of separate counterparts, including facsimiles, each of which, when so
executed and delivered, shall be an original, and all such counterparts shall
together constitute one and the same instrument.

         11.14 AGENT'S OR BANK'S CONSENT.

         Whenever the Agent's or any Bank's consent is required to be obtained
under this Agreement or any of the other Loan Documents as a condition to any
action, inaction, condition or event, the Agent and each Bank shall be
authorized to give or withhold such consent in its sole discretion and to
condition its consent upon the giving of additional collateral, the payment of
money or any other matter.

         11.15 EXCEPTIONS.

         The representations, warranties and covenants contained herein shall be
independent of each other, and no exception to any representation, warranty or
covenant shall be deemed to be an exception to any other representation,
warranty or covenant contained herein 


                                     -114-

unless expressly provided, nor shall any such exceptions be deemed to permit any
action or omission that would be in contravention of applicable Law.

         11.16 CONSENT TO FORUM; WAIVER OF JURY TRIAL.

         EACH LOAN PARTY HEREBY IRREVOCABLY CONSENTS TO THE NONEXCLUSIVE
JURISDICTION OF THE COURT OF COMMON PLEAS OF ALLEGHENY COUNTY AND THE UNITED
STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA, AND WAIVES
PERSONAL SERVICE OF ANY AND ALL PROCESS UPON IT AND CONSENTS THAT ALL SUCH
SERVICE OF PROCESS BE MADE BY CERTIFIED OR REGISTERED MAIL DIRECTED TO SUCH LOAN
PARTY AT THE ADDRESSES PROVIDED FOR IN SECTION 11.6 AND SERVICE SO MADE SHALL BE
DEEMED TO BE COMPLETED UPON ACTUAL RECEIPT THEREOF. EACH LOAN PARTY WAIVES ANY
OBJECTION TO JURISDICTION AND VENUE OF ANY ACTION INSTITUTED AGAINST IT AS
PROVIDED HEREIN AND AGREES NOT TO ASSERT ANY DEFENSE BASED ON LACK OF
JURISDICTION OR VENUE OR INCONVENIENT FORUM. EACH LOAN PARTY, THE AGENT AND THE
BANKS HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM
OF ANY KIND ARISING OUT OF OR RELATED TO THIS AGREEMENT, ANY OTHER LOAN DOCUMENT
OR THE COLLATERAL TO THE FULL EXTENT PERMITTED BY LAW.

         11.17 TAX WITHHOLDING CLAUSE.

         Each Bank or assignee or participant of a Bank that is not organized
under the Laws of the United States of America or a state thereof (each a
"non-US Bank") and each Bank or assignee or participant of a Bank that is not
organized under the Laws of the United Kingdom or a political subdivision
thereof (each, a "non-UK Bank") agrees that it will deliver to each of the
Borrowers and the Agent two (2) duly completed copies of the following: (i) for
a non-US Bank, United States Internal Revenue Service Form W-9, 4224 or 1001, or
other applicable form prescribed by the Internal Revenue Service, certifying
that such Bank, assignee or participant is entitled to receive payments under
this Agreement and the other Loan Documents without deduction or withholding of
any United States federal income taxes, or is subject to such tax at a reduced
rate under an applicable tax treaty, or (ii) Internal Revenue Service Form W-8
or other applicable form or a certificate of such Bank, assignee or participant
indicating that no such exemption or reduced rate is allowable with respect to
such payments and for a non-UK Bank, United Kingdom Inland Revenue Form REF FD
13, or other applicable form prescribed by Inland Revenue, certifying such Bank,
assignee, or participant is entitled to receive payments under this Agreement
and the other Loan Documents without deduction or withholding of any United
Kingdom or English income or other tax. Each Bank, assignee or participant
required to deliver to the Borrowers and the Agent a form or certificate
pursuant to the preceding sentence shall deliver such form or certificate as
follows: (A) each Bank which is a party hereto on the Closing Date shall deliver
such form or certificate at least five (5) Business Days prior to the first date
on which any interest or fees are payable by a Borrower hereunder for the
account of such 


                                     -115-
<PAGE>   125

Bank; (B) each assignee or participant shall deliver such form or certificate at
least five (5) Business Days before the effective date of such assignment or
participation (unless the Agent in its sole discretion shall permit such
assignee or participant to deliver such form or certificate less than five (5)
Business Days before such date in which case it shall be due on the date
specified by the Agent). Each Bank, assignee or participant which so delivers a
Form W-8, W-9, 4224 or 1001 or an Inland Revenue Form REF FD 13 further
undertakes to deliver to each of the Borrowers and the Agent two (2) additional
copies of such form (or a successor form) on or before the date that such form
expires or becomes obsolete or after the occurrence of any event requiring a
change in the most recent form so delivered by it, and such amendments thereto
or extensions or renewals thereof as may be reasonably requested by the
Borrowers or the Agent, either certifying that such Bank, assignee or
participant is entitled to receive payments under this Agreement and the other
Loan Documents without deduction or withholding of any United States federal
income taxes or United Kingdom or English income and other taxes or is subject
to such tax at a reduced rate under an applicable tax treaty or stating that no
such exemption or reduced rate is allowable. The Agent shall be entitled to
withhold United States federal income taxes and Borrowers shall be entitled to
withhold United Kingdom or English income and other taxes at the full
withholding rate unless the Bank, assignee or participant (x) with respect to
United States federal income taxes, establishes an exemption or that it is
subject to a reduced rate as established pursuant to the above provisions or (y)
with respect to United Kingdom or English income or other tax, provides such
Inland Revenue form as set forth above; and, (z) with respect to any Bank, the
provisions of Section 5.8.1 and 5.8.2 shall not apply as to United Kingdom or
English law matters until such Inland Revenue form is provided as set forth in
this Section 11.17. If at any time for any reason under applicable income or
other tax Law of the United Kingdom or England the Borrowers are required to
withhold any portion of any amounts owed to any Bank under this Agreement or the
Notes, such Bank shall not be permitted to claim additional compensation under
Section 5.6 unless it has notified the Agent and the Borrowers of the change in
Law or factual circumstances giving rise to such withholding requirement within
30 days after the occurrence thereof. In such event the Borrowers shall have the
right to require the affected Bank to assign, pursuant to an Assignment and
Assumption Agreement, its entire interest in the Loans and the Loan Documents to
an assignee selected by the Borrowers and consented to by the Agent (prior to
the occurrence and continuance of an Event of Default, such consent not to be
unreasonably withheld) for a purchase price at par.

         11.18 JOINDER OF SUBSIDIARIES.

         Any Consolidated TEC Group Entity which is required to join the Master
Guarantee Agreement pursuant to Section 8.2.8 shall execute and deliver to the
Agent a signature page to the Master Guarantee Agreement and to the Master
Intercompany Subordination Agreement. The Borrowers shall deliver such Guarantor
Joinder and the other documents required by this Section 11.18 to the Agent
within five (5) Business Days after the date of the filing of such Subsidiary's
articles of incorporation if the Subsidiary is a corporation, the date of the
filing of its certificate of limited partnership if it is a limited partnership
or the date of its organization if it is an entity other than a limited
partnership or corporation or, if acquired, the date of acquisition. The Agent
shall have received, for its benefit and the benefit of the Banks 


                                     -116-

opinions of such Loan Party's legal counsel in form and substance satisfactory
to the Agent together with such other documents, certificates and agreements as
the Agent may request to effectuate the provisions of this Section 11.18.
