be paid the same to a Federal Reserve Bank wire transfer confirmation  
number evidencing the wire transfer of such amount to the Federal Reserve

without counterclaim, setoff, condition or qualification, and free and clear of
and without deduction or withholding for or by reason of any present or future  
taxes, levies, imposts, deductions or charges of any nature whatsoever; in the  
event that the Company is compelled by law to make any such deduction of  
withholding, the Company or Trencor shall nevertheless pay to the Bank such  
amounts as will result in the receipt by the Bank of the sum it would have  
received had no such deduction or withholding been required to be made. 

 Section 2.6.	Reduction and Termination
  (a) The Trustee shall  
have the right at any time to permanently reduce, without penalty or  
premium, the Available Amount of the Letter of Credit upon not less than one  
(l) Business Day's prior written notice to the Bank by the Trustee in the form  
of Exhibit D or H to the Letter of Credit, designating the date (which shall be 
a Business Day) of such reduction and the amount of such reduction. Such  
reduction of the Available Amount shall be effective, after receipt of such  
notice, on the Business Day following the date of delivery of such notice. Any  
reduction other than by virtue of a payment at maturity shall be in an amount  
not less than $100,000. 

	(b)	If the Trustee shall partially reduce the Available Amount  
pursuant to paragraph (a) above, the Bank shall then have the right to require  
the Trustee to simultaneously surrender the outstanding Letter of Credit to the 
Bank on the effective date of such partial reduction of the Available Amount  
and to accept on such date, in substitution for the then outstanding Letter of  
Credit, a substitute irrevocable Letter of Credit, dated such date, for an  
amount equal to the amount to which the Available Amount shall have been  
so reduced but otherwise having terms identical to the then outstanding Letter  
of Credit. Alternatively, the Bank in its sole discretion may elect to
deliver to the Trustee a Notice of Amendment to the Letter of Credit in the
form of Exhibit I to the Letter of Credit, dated the effective date of such
partial reduction of the Available Amount of the Letter of Credit and stating
the amount to which the Available Amount has been reduced. 
 Section 2.7.	Reinstatement of the Amount of the Letter of Credit  
(a)  As set forth in the Letter of Credit, the Available Amount of the  
Letter of Credit shall be reduced and reinstated. 
	(b)	The Bank will promptly notify the Trustee, the Company  
and the Remarketing Agent of any reinstatement of the Letter of Credit, but  
failure to provide such notice shall not affect the reinstatement of the Letter
of Credit as provided above. 
	(c)	The Company hereby irrevocably and unconditionally  
instructs the Bank to reinstate the Letter of Credit in accordance with the  
terms of the Letter of Credit. 
	Section 2.8 Disbursement of Drawings
 The Company hereby  
directs the Bank to make payments under the Letter of Credit in the manner  
set forth therein. 

Section 2.9.	Computation of Interest

interest payable by the Company under this Agreement shall be made on the  
basis of a three hundred sixty (360) day year and actual days elapsed. Interest
shall accrue during each period during which interest is computed from and  
including the first day thereof to but excluding the last day thereof. 

  Section 2.10.	Payment Due on Non-Business Day to be Made on  
                Next Business Day

 If any sum becomes payable pursuant to this Agreement  
on a day which is not a Business Day, the date for payment thereof shall be  
extended, without penalty, to the next succeeding Business Day, and such  
extended time shall be included in the computation of interest and fee. 

  Section 2.11.	Late Payments
 If the principal amount of any  
Obligation is not paid when due, such Obligation shall bear interest  
(computed on the basis of a 360 day year and actual days elapsed) from the  
due date thereof until paid in full at a rate per annum equal to the Corporate  
Base Rate from time to time in effect plus 2%, payable on demand. 
	  Section 2.12.	Source of Funds
 All payments made by the Bank  
pursuant to the Letter of Credit shall be made from funds of the Bank, but in  
no event shall such payment be made with funds obtained from any other  
Person. 

	Section 2.13 Extension of Stated Termination Date
 At any  
time there shall remain no more than two and no less than three months to  
the then current Stated Termination Date, the Company may request the  
Bank to extend such Stated Termination Date for a period of one additional  
year. If the Bank, in its sole discretion, elects to extend the Stated  
Termination Date then in effect, it shall deliver to the Trustee a Notice of  
Amendment in the form of Exhibit K to the Letter of Credit (herein referred  
to as a Notice of Extension) designating the date to which the Stated  
Termination Date is being extended. Such extension of the Stated  
Termination Date shall be effective, after receipt of such notice, on the  
Business Day following the date of delivery of such Notice of Extension, and  
thereafter all references in this Agreement to the Stated Termination Date  
shall be deemed to be references to the date designated as such in the most  
recent Notice of Extension delivered to the Trustee. Any date to which the  
Stated Termination Date has been extended in accordance with this Section  
2.13 may be extended in like manner. 
   Section 2.14.	Amendments Upon Extension
  Upon any  
extension of a Stated Termination Date pursuant to Section 2.13 of this  
Agreement, the Bank reserves the right to renegotiate any of the provisions  
hereof.  The Company agrees that notwithstanding Article 9(d)(iii) of the  
Uniform Customs, amendments to the Letter of Credit contemplated by  
Exhibits I and K thereto shall not require acceptance by the beneficiary of the 
Letter of Credit in order to be binding against the Company and the Bank. 
  Section 2.15.	Operative Documents
  Payment Documents (as  
defined in the Letter of Credit) include documents sent by telecopier and  
tested telex with the original subsequently sent to the Bank.  In the event of  
any discrepancy between the versions of the Payment Documents submitted to

all purposes shall be the version submitted to the Bank by telecopier or tested
telex.

Article VII	Miscellaneous

 Section 7.1.	No Deductions; Increased Costs';. (a) Each  
payment by the Company to the Bank under this Agreement or any other  
Related Document shall be made without setoff or counterclaim and without  
withholding for or on account of any present or future taxes (other than  
overall net income taxes on the recipient imposed by any jurisdiction having  
control of such recipient) imposed by or within the jurisdiction in which the  
Company is domiciled, any jurisdiction from which the Company makes any  
payment hereunder, or (in each case) any political subdivision or taxing  
authority thereof or therein. If any such withholding is so required, the  
Company shall make the withholding, pay the amount withheld to the  
appropriate governmental authority before penalties attach thereto or interest  
accrues thereon and forthwith pay such additional amount as may be  
necessary to ensure that the net amount actually received by the Bank free and  
clear of such taxes (including such taxes on such additional amount) is equal  
to the amount which the Bank would have received had such withholding not  
been made. If the Bank pays any amount in respect of any such taxes,  
penalties or interest, the Company shall reimburse the Bank for that payment  
on demand in the currency in which such payment was made. If the Company  
pays any such taxes, penalties or interest, it shall deliver official tax
receipts evidencing that payment or certified copies thereof to the Bank on or
before the thirtieth day after payment. 
	(b)	If any newly adopted, or any change in any, law, treaty,  
regulation, guideline or directive or any new or modified interpretation of any 
of the foregoing by any authority or agency charged with the administration  
or interpretation thereof or any central bank or other fiscal, monetary or
other authority having jurisdiction over the Bank or the transactions
contemplated by this Agreement (whether or not having the force of law) shall: 
	(i)	limit the deductibility of interest on funds obtained by the  
Bank to pay any of its liabilities or subject the Bank to any tax, duty, 
charge, deduction or withholding on or with respect to payments relating to the 
Bonds, the Letter of Credit or this Agreement, or any amount paid or to be  
paid by the Bank as the issuer of the Letter of Credit (other than any tax  
measured by or based upon the overall net income of the Bank imposed by  
any jurisdiction having control over the Bank); 
	(ii)	impose, modify, require, make or deem applicable to the  
Bank any reserve requirement, capital requirement, special deposit  
requirement, insurance assessment or similar requirement against any assets  
held by, deposits with or for the account of, or loans, letters of credit or  
commitments by, an office of the Bank; 
	(iii)	change the basis of taxation of payments due the Bank  
under this Agreement or the Bonds (other than by a change in taxation of the  
overall net income of the Bank); 
	(iv)	cause or deem letters of credit to be assets held by the Bank  
and/or as deposits on its books; or 
	(v)	impose upon the Bank any other condition with respect to  
any amount paid or payable to or by the Bank or with respect to this  
Agreement, the Letter of Credit or the Bonds; 
and the result of any of the foregoing is to increase the cost to the Bank of  
making any payment or maintaining the Letter of Credit, or to reduce the  
amount of any payment (whether of principal, interest or otherwise)  
receivable by the Bank hereunder or under any other Related Document, or to  
reduce the rate of return on the capital of the Bank or to require the Bank to  
make any payment on or calculated by reference to the gross amount of any  
sum received by it, in each case by an amount which the Bank in its  
reasonable judgment deems material, then: 
	(1)	the Bank shall promptly notify the Company in writing of  
such event; 
	(2)	the Bank shall promptly deliver to the Company a  
certificate stating the change which has occurred or the reserve requirements  
or other costs or conditions which have been imposed on the Bank or the  
request, direction or requirement with which it has complied, together with  
the date thereof, the amount of such increased cost, reduction or payment and  
a reasonably detailed description of the way in which such amount has been  
calculated, and the Bank's determination of such amounts, absent fraud or  
manifest error, shall be conclusive; and 
	(3)	the Company shall pay to the Bank, from time to time as  
specified by the Bank, in the notice referred to in clause (l) above, such an  
amount or amounts as will compensate the Bank for such additional cost,  
reduction or payment. 
The protection of this Section 7.1(b) shall be available to the Bank regardless 
of any possible contention of invalidity or inapplicability of the law,  
regulation or condition which has been imposed; provided, however, that if it  
shall be later determined by the Bank that any amount so paid by the  
Company pursuant to this Section 7.1(b) is in excess of the amount payable  
under the provisions hereof, the Bank shall refund such excess amount to the  
Company. 
    Section 7.2.	Right of Setoff
 (a) Upon the occurrence and  
during the continuance of an Event of Default, the Bank is hereby authorized  
at any time and from time to time without notice to the Company (any such  
notice being expressly waived by the Company), and to the fullest extent  
permitted by law, to setoff, to exercise any banker's lien or any right of  
attachment and apply any and all balances, credits, deposits (general or  
special, time or demand, provisional or fixed), accounts or monies at any time  
held and other indebtedness at any time owing by the Bank to or for the  
account of the Company (irrespective of the currency in which such accounts,  
monies or indebtedness may be denominated and the Bank is authorized to  
convert such accounts, monies and indebtedness into dollars) against any and  
all of the Obligations of the Company, whether or not the Bank shall have  
made any demand hereunder or thereunder. 
	(b)	The rights of the Bank under this Section 7.2 are in  
addition to, in augmentation of, and, except as specifically provided in this  
Section 7.2, do not derogate from or impair other rights and remedies  
(including, without limitation, other rights of setoff) which the Bank may  
have. 
  
Section 7.3.	Indemnity, Costs, Expenses and Taxes
  The Company agrees to indemnify and hold the Bank harmless from and against,  
and to pay on demand, any and all claims, damages, losses, liabilities,  
reasonable costs and expenses whatsoever which the Bank may incur or suffer  
by reason of or in connection with the execution and delivery of this  
Agreement or the Letter of Credit, or any other documents which may be  
delivered in connection with this Agreement or the Letter of Credit, or in  
connection with any payment under the Letter of Credit, including, without  
limitation, the reasonable fees and expenses of counsel for the Bank with  
respect thereto and with respect to advising the Bank as to its rights and  
responsibilities under this Agreement and the Letter of Credit and all  
reasonable fees and expenses, if any, in connection with the enforcement or  
defense of the rights of the Bank in connection with this Agreement or the  
Letter of Credit, or the collection of any monies due under this Agreement or  
such other documents which may be delivered in connection with this  
Agreement or the Letter of Credit; except, only if, and to the extent that any  
such claim, damage, loss, liability, cost or expense shall be caused by the  
willful misconduct or gross negligence of the Bank in performing its  
obligations under this Agreement or in making payment against a drawing  
presented under the Letter of Credit which does not substantially comply with  
the terms thereof (it being understood and agreed by the parties hereto that in 
making such payment the Bank's exclusive reliance on the documents  
presented to the Bank in substantial compliance with the terms of the Letter  
of Credit as to any and all matters set forth therein, whether or not any  
statement or any document presented pursuant to the Letter of Credit proves  
to be forged, fraudulent, invalid or insufficient in any respect or any
statement therein proves to be untrue or inaccurate in any respect whatsoever
shall not be deemed willful misconduct or gross negligence of the Bank). The  
Company, upon demand by the Bank at any time, shall reimburse the Bank  
for any legal or other expenses incurred in connection with investigating or  
defending against any of the foregoing except if the same is directly due to
the Bank's gross negligence or willful misconduct.  Promptly after receipt by
the Bank of notice of the commencement, or threatened commencement, of any  
action subject to the indemnities contained in this Section 7.3, the Bank shall 
notify the Company thereof; but failure to so notify shall not relieve the  
Company from any liability which it may have to the Bank hereunder.  The  
obligations of the Company under this Section 7.3 shall survive payment of  
any funds due under this Agreement or the expiration of the Letter of Credit. 

  Section 7.4.	Obligations Absolute
 The obligations of the  
Company under this Agreement shall be absolute, unconditional and  
irrevocable, and shall be paid strictly in accordance with the terms of this  
Agreement, under all circumstances whatsoever, including, without  
limitation, the following circumstances: 
	(i)	any lack of validity or enforceability of the Letter of Credit,  
the Bond Documents, the Credit Agreement, the Astec Guaranty, or any other  
agreement or instrument relating thereto (collectively, the Related  
Documents); 
	(ii)	any amendment or waiver of or any consent to departure  
from all or any of the Related Documents; 
	(iii)	the existence of any claim, set-off, defense or other rights  
which the Company may have at any time against the Trustee, the  
Remarketing Agent or any other beneficiary or any transferee thereof, the  
Bank (other than the defense of payment to the Bank in accordance with the  
terms of this Agreement), or any other person or entity, whether in  
connection with this Agreement, the Bond Documents or any unrelated  
transaction; 
	(iv)	any statement or any other document presented under the  
Letter of Credit proving to be forged, fraudulent, or invalid or any statement  
therein being untrue or inaccurate in any respect whatsoever; and 
	(v)	payment by the Bank under the Letter of Credit against  
presentation of a certificate which substantially complies with the terms of 
the Letter of Credit. 
   Section 7.5.	Liability of the Bank
 The Company assumes all  
risks of the acts or omissions of the Trustee, the Remarketing Agent, the  
Tender Agent, or any other agent of the Trustee and any transferee of the  
Letter of Credit with respect to its use of the Letter of Credit. Neither the  
Bank nor any of its officers or directors shall be liable or responsible for:
 (a) the use which may be made of the Letter of Credit or for any acts or
 omissions of the Trustee and any transferee in connection therewith; (b) the
 validity or genuineness of documents, or of any endorsement(s) thereon, even
 if such documents should in fact prove to be in any or all respects invalid,
 fraudulent or forged; (c) payment by the Bank against presentation of
 documents which do not comply with the terms of the Letter of Credit,
 including failure of any documents to bear any reference or adequate reference
 to the Letter of Credit; or (d) any other circumstances whatsoever in making
 or failing to make payment under the Letter of Credit; provided, however, that
 the Company shall have a claim against the Bank, and the Bank shall be
 liable to the Company, to the extent of any direct, as opposed to
 consequential, damages suffered by the Company which the Company proves were
 caused by (i) the Bank's wilful misconduct or gross negligence in
 determining whether documents presented under the Letter of Credit comply with
 the terms of the Letter of Credit or (ii) the Bank's wilful or grossly
 negligent failure to make lawful payment under the Letter of Credit after the
 presentation to the Bank  
by the Trustee or a successor trustee under the Indenture of a certificate  
strictly complying with the terms and conditions of the Letter of Credit (it  
being understood that in making such payment the Bank's exclusive reliance  
on the documents presented to the Bank in substantial compliance with the  
terms of the Letter of Credit as to any and all matters set forth therein  
whether or not any statement or any document presented pursuant to the  
Letter of Credit proves to be forged, fraudulent, invalid or insufficient in
 any respect or any statement therein proves to be untrue or inaccurate in any  
respect whatsoever shall not be deemed willful misconduct or gross  
negligence of the Bank). 
  Section 7.6.	Waiver of Rights by the Bank
 No course of  
dealing or failure or delay on the part of the Bank in exercising any right,  
power or privilege hereunder or under the Letter of Credit or this Agreement  
shall operate as a waiver thereof, nor shall a single or partial exercise 
thereof  preclude any other or further exercise or the exercise of any other
 right or  
privilege. The rights of the Bank under the Letter of Credit and the rights of  
the Bank under this Agreement are cumulative and not exclusive of any rights  
or remedies which the Bank would otherwise have.  No notice to or demand  
on the Company in any case shall entitle the Company to any other or further  
notice or demand in the same, similar or other circumstances. 

   Section 7.7.	Severability
 In case any one or more of the  
provisions contained in this Agreement should be invalid, illegal or  
unenforceable in any respect, the validity, legality and enforceability of the  
remaining provisions contained herein shall not in any way be affected or  
impaired thereby. The parties shall endeavor in good faith negotiations to  
replace the invalid, illegal or unenforceable provisions with valid provisions  
the economic effect of which comes as close as possible to that of the invalid, 
illegal or unenforceable provisions. 
    Section 7.8.	Governing Law
 This Agreement shall be  
governed by and construed in accordance with the laws of the State of Illinois, 
without giving effect to Illinois' choice of law principles.

provided may be extended in a like manner.

event shall such payment be made with funds obtained from the Issuer or the  
Company or any other person.
