  	Section 2.02.  Issuance of Bonds; Terms of Bonds.  (a)  General   
Provisions.   
   
 The Bonds shall: (i)	be dated as provided in Section 2.02(i) below,     
	      
	       	(ii)	bear interest initially in the Weekly Rate Mode    
and, thereafter, as set forth in paragraphs (b) through (f) of this Section, 
until paid, at the rates therein provided (computed, while the Bonds are in
the Weekly Rate Mode, the CP Rate Mode or the Daily Rate Mode, on the basis   
of a 365- or 366-day year, for the actual number of days elapsed and,     
while the Bonds are in the Adjustable Rate Mode, on the basis    
of a 360-day year, composed of twelve 30-day months), payable on each   
Interest Payment Date,    
	      
	       	(iii)	all be in the same Mode at the same time, and     
	      
	       	(iv)	mature on April 1, 2019.    
	      
	  	(b)	Weekly Rate Provisions.    
			(i) The Bonds shall bear interest at  
 a Weekly Rate from the Closing Date (if applicable) and from each   
Weekly Rate Conversion Date to the earlier of their redemption, the following   
Conversion Date or their maturity date.  The Weekly Rate for each Weekly   
Interest Period shall be the lowest rate of interest which will, in the sole   
judgment of the Remarketing Agent, having due regard for prevailing   
financial market conditions, permit the Bonds to be remarketed at par on the   
first day of such Weekly Interest Period. Notwithstanding the foregoing, the   
Weekly Rate so established shall be not more than the Maximum Rate. Each     
determination of a Weekly Rate by the Remarketing Agent shall be conclusive   
and binding.      
   
	Notwithstanding the foregoing, if at any time the Remarketing    
Agent shall fail to determine a Weekly Rate as set forth above, then, until the 
Remarketing Agent shall next determine the Weekly Rate in such fashion, the   
Weekly Rate shall be the rate from time to time established as the J.J.
Kenney index rate for high grade tax-exempt obligations having maturities    
of 30 days.  If such index rate is not available, the Weekly Rate shall be the 
rate from time to time established by the Public Securities Association   
Municipal Swap Index, and if such index is not available, the Weekly Rate   
shall be the rate from time to time established by such other comparable index  
as may be selected by the Company upon notice to the Trustee.  In no event   
however may the interest rate on the Bonds exceed the Maximum Rate.    
	      
	  	(ii)	On Tuesday (unless Tuesday is not a Business Day,    
then on the next preceding Monday; unless Monday and Tuesday are not   
Business Days, then on the next subsequent Wednesday, whether or not a   
Business Day) of each calendar week during a Weekly Rate Period,     
with respect to each Weekly Interest Period, the Remarketing Agent shall   
determine and furnish to the Trustee, the Company, the Bank, and the Tender   
Agent, if any, the Weekly Rate for the ensuing Weekly Interest Period.  On   
the Business Day preceding each Weekly Rate Interest Payment Date,     
the Trustee shall furnish to the Company, the Bank and, if the Bonds are not   
in a Book-Entry  System, to the Tender Agent, the Weekly Rates applicable to   
the Bonds from the time of the prior notice of such rates.  Should any Owner   
or Beneficial Owner request such in writing, the Remarketing Agent shall   
also furnish (by first class mail, postage prepaid) the Weekly Rate to such     
requesting Owner or Beneficial Owner.    
 	      
  	(c)	Daily Rate Provisions.  (i)  The Bonds shall bear interest at a Daily 
Rate from the Closing Date (if applicable) and from each Daily Rate Conversion
Date to the earlier of their redemption, the following Conversion Date or their 
maturity date.  The Daily Rate for each Daily Interest Period shall be the   
interest rate determined by the Remarketing Agent on the first day of such   
Daily Interest Period (by not later than 11:00 a.m.), which    
shall be the lowest rate of interest which will, in the sole judgment of the   
Remarketing Agent having due regard for prevailing financial market   
conditions, permit the Bonds to be remarketed at par on the said first day of   
such Daily Interest Period. Notwithstanding the foregoing, the Daily Rate so    
established shall be not more than the Maximum Rate. In the event no Daily   
Rate is determined by the Remarketing Agent for a Daily Interest Period, then   
the Bonds shall automatically bear interest at the last Daily Rate previously   
determined pursuant to this Indenture.  Each determination of a Daily Rate by   
the Remarketing Agent shall be conclusive and binding.   	       
  	(ii)	On the Business Day preceding each Interest    
Payment Date during each Daily Rate Period, the Remarketing Agent will   
furnish to the Trustee, and the Trustee will furnish to the Bank,     
the Company, and the Tender Agent, if any, the Daily Rates applicable to the   
Bonds during such Daily Rate  Period.  Should any Owner or Beneficial   
Owner request in writing the Daily Rate applicable to the Bonds for any   
particular day, the Remarketing Agent will furnish such Daily Rate     
to such requesting Owner or Beneficial Owner.    
	      
  	(d)	CP Rate Provisions.  (i) The Bonds shall bear interest at a CP Rate from 
each CP Rate Conversion Date or CP Rate Reset Date, as appropriate, to the   
earlier of their redemption, the following Conversion Date or the following   
CP Rate Reset Date.  In the case of each CP Rate Period, on the first day   
thereof, the Remarketing Agent shall determine (i) the duration of the CP   
Rate Period and (ii) the CP Rate which shall apply during such CP    
Rate Period.  The duration of the CP Rate Period so determined shall be that   
which, in the sole judgment of the Remarketing Agent will provide the lowest   
overall interest cost with respect to the Bonds, with due regard to prevailing 
financial market conditions, foreseeable changes in such conditions, the   
anticipated duration of the period the Bonds may remain in the CP Rate   
Mode, and such other factors which  the Remarketing Agent, in its sole   
judgment, shall deem relevant and economically advantageous to     
consider.  Upon determination of the duration of the CP Rate  Period, the   
Remarketing Agent shall determine the CP Rate which shall be in effect   
during such CP Rate Period, which shall be the lowest rate of interest which,   
in the sole judgment of the Remarketing Agent, having due regard to     
prevailing financial market conditions, will permit the Bonds to be    
sold at par on the first day of such CP Rate Period.  Notwithstanding the   
foregoing, the CP Rate so determined shall not be more than the Maximum   
Rate.  Unless and until the Company elects to effect a conversion of the Bonds 
from the CP Rate Mode to another Mode, the Remarketing Agent shall    
continually redetermine the duration of, and the CP Rate to be effective   
during, each new CP Rate Period, which will commence, without further   
action on the part of the Company, on each CP Rate Reset Date.  If on any CP   
Rate Reset Date, the Remarketing Agent shall fail to determine either    
the duration of, or the CP Rate to be effective during, the CP Rate Period   
which commences on  such date, then, without further action on the part of   
any person, the Bonds shall automatically convert to the Weekly Rate Mode     
upon such date, and the Bonds shall thereupon bear interest of the    
Weekly Rate.  Upon such event the Trustee shall promptly notify the Owners,   
the Company, the Tender Agent, if any, and the Bank of such automatic   
conversion.  Each determination by the Remarketing Agent pursuant to this     
paragraph shall be conclusive and binding.    
	      
  	(ii)	On the first day of each CP Rate Period, the Remarketing Agent shall   
furnish to the Trustee, the Bank, the Company, and, if the Bonds are not in a   
Book-Entry System, the Tender Agent, notice of the duration of such CP Rate   
Period and the CP Rate to be effective during such     
CP Rate Period.  Should any Owner or Beneficial Owner request    
notice of such items in writing, the Remarketing Agent shall provide such   
notice (by first class mail, postage prepaid) to such requesting Owner or   
Beneficial Owner.    
	      
  	(e)	Adjustable Rate Provisions.  The Bonds shall bear    
interest at an Adjustable Rate from each Adjustable Rate Conversion Date or   
each Adjustable Rate Reset Date, as appropriate, to the  earlier of their   
redemption, the following Conversion Date, the following Adjustable Rate   
Reset Date, or the following date on which the Bonds shall be subject to    
mandatory tender for purchase pursuant to Section 2.04  hereof.  Upon a   
conversion of the Bonds to the Adjustable Rate Mode, the duration of the   
initial Adjustable Rate Period shall be that period specified in the Company's  
conversion notice delivered pursuant to Section 2.02(f)(i) for the    
purpose of effecting such conversion.  An Adjustable Rate Period shall be of   
at least one month's duration and shall end on the day preceding the first   
Business Day of a calendar month or, if  such Adjustable Rate Period     
extends to the final maturity of the Bonds, such final maturity date.     
The Bonds thereupon shall remain in the Adjustable Rate Mode for as long as   
the Company shall continue to deliver timely notices pursuant to Section   
2.02(f)(i) specifying the duration of the next subsequent Adjustable Rate     
Period which is to commence on the expiration of any current Adjustable Rate   
Period.  The Remarketing Agent, on or prior to the commencement of each    
Adjustable Rate Period, shalldetermine the Adjustable Rate to be borne by the   
Bonds during such Adjustable Rate Period, which     
shall be the lowest rate which, in its sole judgment having due    
regard for prevailing financial market conditions, will permit the Bonds to be 
sold at par on the first day of such Adjustable Rate Period.      
 Notwithstanding the foregoing, the Adjustable Rate shall not be    
more than the Maximum Rate.  If,  during any period the Bonds shall be in   
the Adjustable Rate Mode, either (i) the Company shall not     
deliver a timely conversion notice specifying the duration of the    
next subsequent Adjustable Rate Period, or (ii) on or prior to any Adjustable   
Rate Reset Date the Remarketing Agent shall fail to  determine the   
Adjustable Rate to be borne by the Bonds during such Adjustable Rate Period,   
then, any other provision hereof notwithstanding, the Bonds, without    
further action on the part of any other person, shall automatically convert to 
the Weekly Rate Mode on the date which otherwise would have been the   
Adjustable Rate Reset Date and, the Bonds shall thereupon bear interest at     
the Weekly Rate determined pursuant to Section 2.02(b)(i).  Upon    
such event, the Trustee shall promptly notify the Owners, the Company, the   
Tender Agent, if  any, and the Bank of such automatic     
conversion.  Each determination of an Adjustable Rate by the    
Remarketing Agent shall be conclusive and binding.     
	      
  	(f)	Conversion Options.  (i)  In General.  The interest    
rate Mode of the Bonds shall be converted from one Mode to another, and an   
Adjustable Rate Period of one duration shall be converted to an Adjustable   
Rate Period of the same or another duration, if the Company shall notify     
the Trustee, the Tender Agent, the Bank, and the Remarketing    
Agent of its election to effect such a conversion and each other condition to   
any such conversion set forth herein shall have been satisfied.  The   
Company"s conversion notice shall specify the date on which the Conversion   
Date will occur (which date shall be not sooner than 25 days after the date    
such notice is given) and if the conversion is to an Adjustable Rate Period,   
shall specify the Interest Payment Date which shall be the day following the   
last day of such Adjustable Rate Period. Notwithstanding the foregoing, no     
conversion from a Short Term Mode to a Long Term Mode or from    
a Long Term Mode to a Short Term Mode (as such terms are defined in   
Section 5.03(d) below), and no conversion effected in connection with either a 
change in the Bank issuing the Letter of Credit supporting payment of the     
Bonds, a change in the security for the Bonds, or an amendment to    
this Indenture or the Agreement, shall be effective unless the Company has   
delivered with such  notice an opinion of Bond Counsel     
(which opinion must be confirmed on the Conversion Date) stating    
that such conversion will not  adversely affect the excludability from gross   
income of interest on the Bonds for federal income tax purposes. The   
Conversion Date shall be the date specified in the Company notice; provided   
that no conversion from the Adjustable Rate Mode or the CP Rate Mode    
shall be effective prior to the Business Day following the last day of the   
Adjustable Rate Period or CP Rate Period, as the case  may be, which is then   
in effect. In the event any condition precedent to conversion (including, but  
not limited to, the establishment by the Remarketing Agent of the    
initial interest rate to be in effect after the Conversion Date or, if required,
the   
delivery of the Bond Counsel opinion described above) is not satisfied on or   
prior to the Conversion Date, the Bonds shall nonetheless be subject to     
mandatory tender on the Conversion Date and, upon such date, the    
Bonds, without any further action  on the part of any person, shall   
automatically convert to the Weekly Mode, and the Bonds shall     
thereupon bear interest at the Weekly Rate determined pursuant to    
Section 2.02(b)(i).    
	      
  	(ii)	Conversion Notice.  At least 20 days prior to each    
Conversion Date, the Trustee shall  give to each Owner notice by certified   
mail stating:  (A) the Conversion Date, (B) that on the     
Conversion Date, the Bonds are subject to mandatory tender and    
purchase, (C) that, subject to clause  (E) below, all Owners who fail to tender 
their Bonds for purchase on the mandatory tender date will     
nonetheless be deemed to have tendered their Bonds for purchase    
on such date, (D) that, subject   to clause (E) below, any Bonds not delivered
to the Tender Agent  on or prior to the mandatory  tender date, for which   
there has been irrevocably deposited in trust with the Trustee or the Tender   
Agent on or prior to the mandatory tender date Available Moneys    
sufficient to pay the purchase price of such Undelivered Bonds on the   
mandatory tender date,  shall be deemed to have been so purchased at the   
purchase price, and such Bonds shall no longer be  considered to be   
outstanding for purposes of this Indenture and shall no longer be entitled to   
the benefits of this Indenture, except for the payment of the purchase price   
thereof (and no interest shall  accrue thereon subsequent to the mandatory   
tender date), and (E) that notwithstanding the foregoing, while the Bonds are   
held in the Book-Entry System, Bonds need not be physically tendered    
on the mandatory tender date, and  transfers of beneficial Ownership interests
will be effected by the Securities Depository in accordance with its rules and
procedures.     
	      
	  (iii)	Letter of Credit Interest Coverage.  The interest    
component of each Letter of Credit in effect during any Mode shall be   
sufficient to provide Adequate Interest Coverage (as defined below).  With   
respect to the Weekly Rate Mode, the Daily Rate  Mode, or the CP Rate   
Mode, "Adequate Interest Coverage" shall mean the aggregate amount    
of interest which would accrue on  all Outstanding Bonds (other than Pledged   
Bonds and Company  Bonds) at a rate equal to 10% per annum, computed on   
the basis of a 365-day year, (1) for a period of  forty-eight (48) days, in the 
case  of Bonds in the Weekly Rate Mode or the Daily Rate Mode, and (2)    
for a period of two hundred ninety (290) days, in the case of Bonds in the CP   
Rate Mode or such shorter period acceptable to the Rating Agencies and   
which will not result in a withdrawal or  lowering of any rating on the Bonds 
from that which would otherwise accrue from a longer interest    
coverage period.  Notwithstanding the foregoing, Adequate Interest Coverage   
during the Weekly Rate Mode, the Daily Rate Mode, or the CP Rate Mode   
may cover interest on Bonds at a rate other than 10% per annum if, (1) the   
Company  provides the Trustee with an opinion of Bond Counsel to the effect    
that such coverage and the effect of such coverage upon clause (b) of the   
definition of "Maximum Rate" herein will not adversely  affect the exclusion   
from gross income of interest on the Bonds for federal income tax purposes,   
and   (2) if the applicable rate is to be less than 10% per annum, such    
lower rate will not result in a  withdrawal or lowering of any rating on the   
Bonds from that which would otherwise accrue from     
maintaining coverage at the 10% rate.  With respect to the    
Adjustable Rate Mode, "Adequate  Interest Coverage" shall mean the   
aggregate amount of interest  which would accrue on all Outstanding Bonds   
(other than Pledged Bonds and Company  Bonds) at a rate equal to the     
Adjustable Rate to be borne by the Bonds during such Mode,    
computed on the basis of a 360-day  year composed of twelve 30-day months,   
for a period of two  hundred (200) days or with respect to     
an Adjustable Rate Period of less than six months' duration, for a    
period equal to the number of days  in such Adjustable Rate Period plus   
twenty, or in either such case,  such shorter period acceptable     
to the Rating Agencies and which will not result in a withdrawal,    
or lowering of any rating on the Bonds from that which would otherwise   
accrue from a longer  interest coverage period.    
	      
  	(g)	Denominations; Numbering. The Bonds are    
issuable only as registered Bonds without coupons in Authorized   
Denominations.  The Bonds shall be numbered from 1 upwards, provided that     
the number assigned to each definitive Bond shall be prefixed by    
the letter "R." Temporary Bonds shall be prefixed by the letters "TR."   The   
Initial Bond hereinafter described shall be numbered T-1.    
	      
	  (h)	Payment Terms. Principal of, and premium, if any,    
on, the Bonds shall be payable by  the Trustee from moneys held by the   
Trustee in the Bond Fund to the Owners upon presentation     
and surrender of the Bonds as the same become due at the corporate    
trust office of the Trustee.  Interest on the Bonds shall be paid by the 
Trustee   
by check drawn  upon the Trustee and mailed by first class mail on the   
respective Interest Payment Dates to the Owners at their addresses shown on     
 the registration books of the Trustee, or such other addresses as are    
furnished to the Trustee (in form satisfactory to the Trustee) by such Owners, 
as of the close of business on the Record Date with respect to such Interest   
Payment Date; provided that payment of interest shall be made by the     
Trustee by wire transfer to any Owner of $1,000,000 or more in    
aggregate principal amount of Bonds upon such Owner providing the Trustee   
with written wire transfer instructions acceptable to the Trustee before the   
applicable Record Date. If and to the extent there  shall be a default in the   
payment of the interest due on an Interest Payment Date, such    
defaulted interest shall be paid to the Owners in whose names any such Bonds   
(or any Bond or Bonds issued upon registration of transfer or exchange   
thereof) are registered at the close of business on the  Business Day next   
preceding the date of payment of such defaulted interest. Payment of the   
principal  or purchase price of, and the premium, if any, and interest on, the 
Bonds shall be made in such  lawful money of the United States     
of America as, at the respective times of payment, shall be legal    
tender for the payment of public and  private debts.     
	      
  	(i)	Dating.  The Bonds shall be dated April 1, 1994    
and initially bear interest from the  Closing Date, and thereafter shall bear   
interest from the Interest Payment Date next preceding the     
date of authentication, unless (i) authenticated prior to the first    
Interest Payment Date, in which  event such Bonds shall bear interest from   
the Closing Date, (ii)  authenticated on an Interest Payment     
Date, in which event such Bonds shall bear interest from the date of    
authentication, or (iii)   authenticated after a Record Date and before the   
following Interest  Payment Date, in which event  such Bonds shall bear   
interest from the following Interest Payment  Date. If, as shown by the   
records   of the Trustee, interest on the Bonds is in default, Bonds issued in  
exchange for Bonds surrendered  for registration of transfer or exchange shall 
bear interest from the  date to which interest has been  paid in full on the   
Bonds, or, if no interest has been paid on the  Bonds, from the Closing Date.   
	      
	  Section 2.03.  Optional Tender.  (a)  While the Bonds are in    
the Weekly Rate Mode, any  Outstanding Bond or portion thereof in an   
Authorized Denomination (except any Pledged Bond or Company ond) shall   
be purchased on the demand of the registered  Owner thereof on any Business     
Day at a price equal to 100% of the principal amount thereof, plus    
accrued and unpaid interest  thereon to the date of purchase, upon delivery   
(by telecopy or  otherwise) to the Tender Agent at its Principal Office on any 
Business Day, of the following:   	      
  	(i)	a written irrevocable notice, which will be effective    
upon receipt, which (A) states the  name and address of the registered Owner,   
the principal amount of  such Bond (and the portion  thereof to be tendered, if 
less than the full principal amount is to be  tendered) and the Bond number,    
and (B) states the date on which such Bond shall be so purchased,    
which date shall be a Business Day  not prior to the seventh day next   
succeeding the date of the delivery  of such notice to the Tender     
Agent; and  	      
	  (ii)	such Bond (with all necessary endorsements and    
guarantee of signature) attached to such notice; provided, however, that the   
purchase price of such Bond shall be paid only upon the     
delivery of the Bond to the Tender Agent and provided such Bond    
shall conform in all material  respects to the description thereof in such   
notice; and provided, further, that if the registered Owner     
of the tendered Bond is an open-ended diversified management    
investment company (registered  under the Investment Company Act of 1940,   
as amended), the  delivery required under this paragraph  (ii) need not be   
made until 11:00 a.m., New York City time, on the  date such Bond is to be     
purchased from such registered Owner. Undelivered Bonds shall be    
deemed to have been delivered  at the time and on the date required, and as of 
such date and time  shall no longer be deemed to be Outstanding under this   
Indenture.  The registered Owner of any  Undelivered Bond shall be entitled     
only to the purchase price payable for such Bond on the required    
delivery date thereof, and such purchase price shall be paid to such registered
Owner only upon  surrender of such Bond to the Tender Agent.       
 	Notwithstanding the foregoing, if the Bonds in the Weekly    
Rate Mode are held in a  Book-Entry System, a Beneficial Owner shall have   
the right to  optionally tender for purchase its  beneficial interest in any   
Outstanding Bonds (or portion thereof in an Authorized Denomination) at     
 the purchase price set forth above, which right may be exercised as    
follows.  Such right shall be exercised by delivery by the Beneficial Owner to
the Remarketing  Agent at its Principal Office of a   notice identifying the   
name and address of such Beneficial Owner  and stating that such Beneficial     
Owner will cause its beneficial interest (or portion thereof in an    
Authorized Denomination) to be  purchased, the amount of such interest to be   
purchased, the date on  which such interest will be purchased (which date   
shall be a Business Day at least seven days after delivery of such notice to 
the  Remarketing Agent) and specifying the Remarketing Agent as the    
Participant through which the   Beneficial Owner maintains its interest. Upon   
delivery of such  notice, the Beneficial Owner shall cause its beneficial   
Ownership interest in the Bonds (or the portion  thereof specified in the   
foregoing  notice) being purchased to be transferred to the Remarketing   
Agent  at or prior to 11:00 a.m., on the optional tender date, in accordance   
with the rules and procedures of  the applicable Securities Depository.    
	      
  	(b)	While the Bonds are in the Daily Rate Mode, any    
Outstanding Bond or portion  thereof in an Authorized Denomination (except   
any Pledged Bond  or Company Bond) shall be purchased on the demand of   
the registered Owner thereof on any  Business Day at a price equal to     
100% of the principal amount thereof, plus accrued and unpaid    
interest thereon to the date of  purchase, upon delivery (by telecopy or   
otherwise) to the Tender  Agent at its Principal Office (i) no later than 10:30
a.m. on such Business Day, of a written irrevocable  notice, which will be   
effective  upon receipt, which states the name and address of the registered    
Owner, the principal amount of  such Bond (and the portion thereof to be   
tendered, if less than the  full principal amount is to be tendered) on such   
Business Day and the Bond number, and (ii) no  later than 11:00 a.m. on   
such  Business Day such Bond (with all necessary endorsements and    
guarantees of signature); provided,  however, that the purchase price of such   
Bond shall be paid only  upon the delivery of the Bond to     
the Tender Agent and provided such Bond shall conform in all    
material respects to the description  thereof in such notice. Undelivered Bonds 
shall be deemed to have  been delivered at the time and on the date required,   
and as of such date and time shall no longer  be deemed to be Outstanding     
under this Indenture.  The registered Owner of any Undelivered    
Bond shall be entitled only to the purchase price payable for such Bond on the 
required delivery date  thereof, and such purchase price     
shall be paid to such registered Owner only upon surrender of such    
Bond to the Tender Agent.   
      
  	Notwithstanding the foregoing, if the Bonds in the Daily    
Rate Mode are held in a Book-Entry System, a Beneficial Owner shall have   
the right to optionally tender  for purchase its beneficial     
interest in any Outstanding Bonds (or portion thereof in an    
Authorized Denomination) at the  purchase price set forth above, which right   
may be exercised as  follows. Such right shall be exercised by delivery, by the
Beneficial Owner to the Remarketing Agent at  its Principal Office no later   
than 10:30 a.m., on the date on which the beneficial interest of such    
Beneficial Owner is to be purchased,  of a notice identifying the name and   
address of such Beneficial  Owner and stating that such     
 Beneficial Owner will cause its beneficial interest (or portion    
thereof in an Authorized Denomination) to be purchased, the amount of such   
interest to be  purchased, and specifying the     
Remarketing Agent as the Participant through which the Beneficial    
Owner maintains its interest.  Upon delivery of such notice, the Beneficial   
Owner shall cause its  beneficial Ownership interest in     
 the Bonds (or the portion thereof specified in the foregoing notice)    
being purchased to be transferred   to the Remarketing Agent at or prior to   
11:00 a.m., on the optional  tender date, in accordance with     
 the rules and procedures of the applicable Securities Depository.    
	      
	  	Section 2.04.  Mandatory Tenders.  All Outstanding Bonds    
are subject to mandatory tender  in whole by the Owners to the Tender Agent   
at its Principal Office  on each date described below:     
	      
	  	(a)	On each Conversion Date;     
	      
	  	(b)	On each CP Rate Reset Date;     
	      
	       	(c)	On the second Business Day prior to the expiration    
or termination of the  Letter of Credit (except for a termination because of 
the occurrence of a "default" or an "event of default" under the Reimbursement
Agreement), if the  Trustee has not received  evidence satisfactory to it as   
required by Section 5.03(b) hereof  by the 25th day preceding the     
scheduled Letter of Credit expiration or termination date of    
either an extension of the then  existing Letter of Credit or the issuance of 
an Alternate Credit  Facility meeting the  requirements set forth therefor in 
the Agreement, including the  Maintenance of Rating requirement (as defined in
Section 5.03(b) of this Indenture);        
       	(d)	On the date of substitution of an Alternate Credit    
Facility for the then existing  Letter of Credit if the Trustee has not 
received evidence of a  Maintenance of Rating with   respect thereto by the 25th
day preceding such substitution date;  and    
	      
       	(e)	On each optional redemption date pursuant to    
Section 3.01 hereof for which  the Company has elected to purchase Bonds in   
lieu of an  optional redemption pursuant to Section 3.01(c) hereof; and    
	(f)	On any date on which the Guaranty is released as    
provided in Section 9.05  hereof.    
	      
	  	The purchase price of Bonds subject to mandatory tender    
shall be 100% of the principal  amount thereof (except in the case of a   
mandatory tender described  in paragraphs (c), (d), (e) or (f)     
above, during, but prior to the expiration date of, an Adjustable    
Rate Period in which case the purchase price shall include a premium equal   
to the then applicable  optional redemption premium,     
if any, on the Bonds), plus accrued interest, if any, to the    
mandatory tender date. Not later than 20 days prior to a mandatory tender   
date described in clauses (b), (c),  (d), or (f) above, the Trustee shall     
mail notice to all Owners of Bonds stating that (l) due to the    
occurrence of one of the events   described above (which event shall be   
specified), such Owner"s  Bonds will be subject to mandatory     
tender on the mandatory tender date (which date shall be specified),    
(2) that, subject to clause (4)   below, all Owners who fail to tender their   
Bonds for purchase on  the mandatory tender date will     
nonetheless be deemed to have tendered their Bonds for purchase    
on such date, (3) that, subject to  clause (4) below, any Bonds not delivered 
to the Tender Agent on  or prior to the mandatory tender     
date, for which there has been irrevocably deposited in trust with    
the Trustee or the Tender Agent  on or prior to the mandatory tender date   
Available Moneys  sufficient to pay the purchase price of     
such Undelivered Bonds on the mandatory tender date, shall be    
deemed to have been so purchased at the purchase price, and such Bonds   
shall no longer be considered  to be outstanding for purposes     
of this Indenture and shall no longer be entitled to the benefits of    
this Indenture, except for the payment of the purchase price thereof (and no   
interest shall accrue  thereon subsequent to the   mandatory tender date), and
(4) that notwithstanding the foregoing,  while the Bonds are held in the     
Book-Entry System, Bonds need not be physically tendered on the    
mandatory tender date, and  transfers of beneficial Ownership interests will   
be effected by the  Securities Depository in accordance with its rules and   
procedures.  Notice of mandatory tenders  described in clauses (a) and (e) of   
this  Section shall be given as part of the notice of conversion referenced    
in Section 2.02(f)(ii) hereof or  notice of redemption referenced in Section   
3.04 hereof,  respectively. No failure on the part of the Trustee to give such
notice shall affect the requirement that Bonds  be tendered on the mandatory  
 tender date.   	      
  	When Bonds are not in a Book-Entry System, Undelivered    
Bonds shall, if Available Moneys sufficient to pay the purchase price of such   
Bonds in full and  available for the purchase of such     
Bonds have been deposited with the Tender Agent on the    
mandatory tender date, be deemed to have been tendered for purchase on the   
mandatory tender date, and from    
such date will no longer be     
	  deemed to be Outstanding for purposes of this Indenture. Owners of    
such Bonds shall have no rights     
	  or benefits under this Indenture other than to receive the purchase    
price for such Bonds upon     
	  surrender of such Bonds to the Tender Agent.  Notwithstanding the    
foregoing, if on any mandatory     
	  tender date the Bonds shall be in the Book-Entry System, it shall    
not be necessary that Bonds be     
	  physically tendered to the Tender Agent on the mandatory tender    
date. Transfers of beneficial     
	  Ownership interests shall be effected in accordance with the rules    
and procedures established by the     
	  Securities Depository.    
	      
	  	Upon the occurrence of any mandatory tender described in    
paragraphs (c), (d), or (e) above     
	  during an Adjustable Rate Period, commencing on the date of such    
mandatory tender the Bonds shall     
	  bear interest in a Mode (and, in the case of the Adjustable Rate    
Mode, for an Adjustable Rate     
	  Period) to be designated by the Company by notice to the Trustee    
given to the Trustee at least 25     
	  days prior to such date, provided, however, the said designated    
Mode or Adjustable Rate Period shall     
	  be effective on the mandatory tender date only if each prerequisite    
to a conversion specified in     
	  Section 2.02(f) shall have been satisfied.  If no designation is of a    
Mode or an Adjustable Rate Period     
	  made by the Company, or if the prerequisites of Section 2.02(f)    
have not been satisfied, then, upon     
	  the mandatory tender date, the Bonds shall convert automatically to    
the Weekly Rate Mode, and the     
	  Bonds thereupon shall bear interest at the Weekly Rate determined    
pursuant to Section 2.02(b)(i).    
	      
	  	Section 2.05.  Form of Bonds.  The Bonds and the    
certificate of authentication, the provision     
	  for registration and the form of assignment thereof shall be in    
substantially the form set forth in     
	  Exhibit A hereto, with such appropriate variations, omissions,    
substitutions, insertions, notations,     
	  legends and endorsements as may be deemed necessary or    
appropriate by the officers of the Issuer     
	  executing the same and as shall be permitted or required by the Act    
and this Indenture.    
	      
	  	Section 2.06.  Execution and Authentication of Bonds;    
Limited Obligations.  (a)  The Bonds     
	  shall be executed on behalf of the Issuer with the manual or    
facsimile signature of the President or     
	  the Vice President of the Issuer, and attested, under a manual or    
facsimile impression of the seal of     
	  the Issuer, with the manual or facsimile signature of the Secretary    
or Assistant Secretary of the Issuer.     
	  In case any officer of the Issuer whose signature or a facsimile    
thereof appears on a Bond shall cease     
	  to be such officer before the delivery of such Bond, such signature    
or such facsimile shall nevertheless     
	  be valid and sufficient for all purposes, the same as if such officer    
had remained in the office until     
	  delivery.     
	      
	  	(b)	Except for the Initial Bond which shall be    
registered by the Comptroller of Public     
	  Accounts of the State, no Bond shall be valid or obligatory for any    
purpose or be entitled to any     
	  security or benefit under this Indenture unless and until a certificate    
of authentication on such Bond     
	  substantially in the form of Exhibit A hereto shall have been duly    
executed by the Trustee, or, in the     
	  case of purchased Bonds delivered by the Tender Agent pursuant to    
Section 3.10, by the Tender     
	  Agent.  Any such executed certificate upon any such Bond shall be    
conclusive evidence that such     
	  Bond has been authenticated and delivered under this Indenture.     
The Initial Bond shall be made     
	  payable to Cede & Co., as nominee of the purchaser, pursuant to    
Section 2.12(b) hereof.  The     
	  certificate of authentication on any Bond shall be deemed to have    
been executed by it if signed by     
	  an authorized officer or signatory of the Trustee, or the Tender    
Agent but it shall not be necessary     
	  that the same officer or signatory sign the certificate of    
authentication on all of the Bonds issued     
	  hereunder.    
	      
	  	(c)	The Bonds are not general obligations of the    
Issuer, but are limited obligations     
	  payable solely from Bond proceeds, the revenues of the Issuer from    
the Agreement and other moneys     
	  pledged thereto and held by the Trustee hereunder which constitute    
the Trust Estate.  Such proceeds,     
	  revenues and other moneys are hereby pledged and assigned as    
security for the equal and ratable     
	  payment of the Bonds and shall be used for no other purposes than    
to pay the principal of, premium,     
	  if any, and interest on the Bonds, except as may be otherwise    
expressly authorized in this Indenture     
	  or the Agreement.  The Bonds shall not be a debt of the State, or    
any political subdivision of the     
	  State within the meaning of any constitutional or statutory    
provision whatsoever; and neither the     
	  State nor any political subdivision thereof shall be liable thereon;    
nor in any event shall such Bonds     
	  or obligations be payable out of any funds or properties other than    
the Trust Estate, and then only     
	  to the extent herein provided.  Neither the members of the Issuer    
nor any persons executing the     
	  Bonds shall be liable personally on the Bonds by reason of such    
execution.    
	      
	  	Section 2.07.  Registration and Exchange of Bonds; Persons    
Treated as Owners.  (a)  Bonds     
	  may be transferred only on the registration books of the Issuer for    
the Bonds, maintained by the     
	  Trustee. Upon surrender for transfer of any Bond to the Trustee,    
duly endorsed for transfer or     
	  accompanied by an assignment duly executed by the Owner or the    
Owner"s attorney duly authorized     
	  in writing, the Trustee will authenticate a new Bond or Bonds in an    
equal total principal amount and     
	  registered in the name of the transferee.     
	      
	  	(b)	Bonds may be exchanged for an equal total    
principal amount of Bonds of different     
	  denominations. The Trustee will authenticate and deliver Bonds    
that the Owner making the exchange     
	  is entitled to receive, bearing numbers not then outstanding.     
	      
	  	(c)	The Trustee will not be required to transfer or    
exchange any Bond during the period     
	  beginning 10 Business Days before the mailing of notice calling    
such Bond or any portion of such     
	  Bond for redemption and ending on the redemption date, except as    
provided in Sections 2.03 and     
	  2.04 hereof.     
	      
	  	(d)	The Owner of a Bond shall, except as otherwise    
described herein with respect to     
	  certain rights of Beneficial Owners, be the absolute Owner of the    
Bond for all purposes, and payment     
	  of principal, interest or purchase price shall be made only to or    
upon the written order of the Owner     
	  or the Owner"s legal representative.     
	      
	  	(e)	The Trustee will require the payment by a Owner    
requesting exchange or transfer of     
	  any tax or other governmental charge required to be paid in respect    
of the exchange or transfer but     
	  will not impose any other charge on the Owner.     
	      
	  	(f)	Notwithstanding the foregoing, for so long as the    
Bonds are held under the     
	  Book-Entry System, transfers of beneficial Ownership will be    
effected pursuant to rules and     
	  procedures established by the Securities Depository.     
	       
	  	Section 2.08.  Mutilated, Lost, Stolen, or Destroyed Bonds.     
If any Bond is mutilated, lost,     
	  stolen, or destroyed, the Trustee will authenticate a new Bond of    
the same denomination if any     
	  mutilated Bond shall first be surrendered to the Trustee, and if, in    
the case of any lost, stolen, or     
	  destroyed Bond, there shall first be furnished to the Trustee for the    
benefit of the Issuer, the Trustee,     
	  the Bank, the Company, and the Guarantor evidence of such loss,    
theft, or destruction, together with     
	  an indemnity reasonably satisfactory to the Trustee to save each of    
them harmless from all risks     
	  related thereto, however remote. If the Bond has matured, instead    
of issuing a duplicate Bond, the     
	  Trustee may with the consent of the Company pay the Bond    
without requiring surrender of the Bond     
	  and make such requirements as the Trustee deems fit for its    
protection, including a lost instrument     
	  bond. The Issuer, the Company, the Guarantor, and the Trustee    
may charge their reasonable fees     
	  and expenses in this connection.     
	      
	  	Section 2.09.  Cancellation of Bonds.  Whenever a Bond is    
delivered to the Trustee for     
	  cancellation (upon payment, redemption, or otherwise), or for    
transfer, exchange, or replacement     
	  pursuant to Section 2.07 or 2.08, the Trustee will promptly cancel    
the Bond and deliver the canceled     
	  Bond or a certificate of destruction as appropriate to the Company    
at its request. Upon cancellation     
	  of any tendered Bond by the Tender Agent, the Tender Agent shall    
forward the canceled Bond to     
	  the Trustee.    
	      
	  	Section 2.10.  Temporary Bonds.  Until definitive Bonds are    
ready for delivery, the Issuer may     
	  execute and the Trustee or the Tender Agent will authenticate    
temporary Bonds substantially in the     
	  form of the definitive Bonds, with appropriate variations. The    
Issuer will, without unreasonable delay,     
	  prepare and the Trustee or the Tender Agent will authenticate    
definitive Bonds in exchange for the     
	  temporary Bonds. Such exchange shall be made by the Trustee or    
the Tender Agent without charge.     
	      
	  	Exchanges and transfers shall be made without charge to    
the Owners; provided that in each     
	  case the Trustee shall require the payment by the Owner requesting    
exchange or transfer of any tax     
	  or other governmental charge required to be paid with respect    
thereto.     
	      
	  	Section 2.11.  Conditions Precedent to Authentication and    
Delivery of Bonds.  Upon the     
	  execution and delivery of this Indenture, one initial Bond (the    
"Initial Bond"), representing the     
	  aggregate principal amount of the Bonds, payable to the initial    
purchaser(s), or its (their) designee(s),     
	  executed with the manual or facsimile signatures of the President    
and Secretary of the Issuer,     
	  approved by the Attorney General of the State, and registered and    
manually signed by the     
	  Comptroller of Public Accounts of the State, will be delivered to the    
initial purchaser or its designee.      
	  Upon payment for the Initial Bond, the Trustee shall cancel the    
Initial Bond and deliver to the     
	  Securities Depository on behalf of the purchaser one registered    
definitive Bond for each year of     
	  maturity of the Bonds, in the aggregate principal amount of all    
Bonds for such maturity, registered     
	  in the name of Cede & Co., as nominee for DTC.  Prior to and as a    
condition precedent to the     
	  authentication and delivery of the Bonds there shall be filed with    
and delivered to the Trustee:     
	      
	       	(i)	a copy, duly certified by an authorized    
representative of the Issuer, of the     
	       resolution adopted by the Issuer in accordance with the Act    
authorizing the execution and     
	       delivery of this Indenture and the issuance of the Bonds;     
	      
	       	(ii)	original duly executed and delivered counterparts    
of this Indenture, the     
	       Agreement, the Guaranty, and the Tax Agreement;     
	       
	       	(iii)	an opinion of Bond Counsel to the effect that    
Bonds executed, authenticated     
	       and delivered as provided in this Indenture will be duly and    
validly issued and will constitute     
	       valid and binding limited obligations of the Issuer;    
	      
	       	(iv)	the approving opinion of the Attorney General of    
the State;        
     	  		(v)	the approval of the Texas Department of    
Commerce; and    
	      
	       	(vi)	the duly executed and delivered Initial Letter of    
Credit.     
	      
	  	Section 2.12.  Book-Entry System.  (a)  The Bonds shall be    
issued pursuant to a Book-Entry     
	  System administered by the Securities Depository with no physical    
distribution of Bond certificates     
	  to be made except as provided in this Section 2.12. Any provision    
of this Indenture or the Bonds     
	  requiring physical delivery of the Bonds shall, with respect to any    
Bonds held under the Book-Entry     
	  System, be deemed to be satisfied by a notation on the registration    
books maintained by the Trustee     
	  that such Bonds are subject to the Book-Entry System.     
	      
	  	(b)	The Book-Entry System will be maintained by the    
Securities Depository and the     
	  Participants and Indirect Participants and will evidence beneficial    
Ownership of the Bonds in     
	  Authorized Denominations, with transfers of ownership effected on    
the records of the Securities     
	  Depository, the Participants, and the Indirect Participants pursuant    
to rules and procedures     
	  established by the Securities Depository, the Participants, and the    
Indirect Participants. The principal     
	  of and any premium on each Bond shall be payable to the Securities    
Depository Nominee or any     
	  other person appearing on the registration books maintained by the    
Trustee as the registered Owner     
	  of such Bond or his registered assigns or legal representative at the    
principal office of the Trustee.     
	  So long as the Book-Entry System is in effect, the Securities    
Depository will be recognized as the     
	  Owner of the Bonds for all purposes. Transfer of principal, interest,    
and any premium payments or     
	  notices to Participants and Indirect Participants will be the    
responsibility of the Securities Depository,     
	  and transfer of principal, interest, and any premium payments or    
notices to Beneficial Owners will     
	  be the responsibility of the Participants and the Indirect    
Participants. No other party will be     
	  responsible or liable for such transfers of payments or notices or for    
maintaining, supervising, or     
	  reviewing such records maintained by the Securities Depository, the    
Participants or the Indirect     
	  Participants. While the Securities Depository Nominee or the    
Securities Depository, as the case may     
	  be, is the registered Owner of the Bonds, notwithstanding any other    
provisions set forth herein,     
	  payments of principal of, redemption premium, if any, and interest    
on the Bonds shall be made to     
	  the Securities Depository Nominee or the Securities Depository, as    
the case may be, by wire transfer     
	  in immediately available funds to the account of such Owner.    
Without notice to or the consent of     
	  the Beneficial Owners, the Trustee, with the consent of the    
Company, and the Securities Depository     
	  may agree in writing to make payments of principal, redemption    
price, or purchase price and interest     
	  in a manner different from that set out herein. In such event, the    
Trustee shall make payments with     
	  respect to the Bonds in such manner as if set forth herein.     
	      
	  	(c)	With the consent of the Remarketing Agent and    
the Issuer, the Company may at any     
	  time elect (i) to provide for the replacement of any Securities    
Depository as the depository for the     
	  Bonds with another qualified Securities Depository, or (ii) to    
discontinue the maintenance of the     
	  Bonds under a Book-Entry System. In such event, the Trustee shall    
give 30 days" prior notice of such     
	  election to the Securities Depository (or such fewer number of days    
as shall be acceptable to such     
	  Securities Depository).     
	       
	  	(d)	Upon the discontinuance of the maintenance of the    
Bonds under a Book-Entry     
	  System, the Trustee will cause Bonds to be issued directly to the    
Beneficial Owners of Bonds, or their     
	  designees, as further described below. In such event, the Trustee    
shall make provisions to notify     
	  Participants and the Beneficial Owners of the Bonds, by mailing an    
appropriate notice to the     
	  Securities Depository, or by other means deemed appropriate by the    
Trustee in its discretion, that     
	  Bonds will be directly issued to the Beneficial Owners of Bonds as    
of a date set forth in such notice,     
	  which shall be a date at least 10 days after the date of mailing of    
such notice (or such fewer number     
	  of days as shall be acceptable to the Securities Depository).     
	      
	  	(e)	In the event that Bonds are to be issued to the    
Beneficial Owners of the Bonds, or     
	  their designees, the Trustee, at the expense of the Company, shall    
promptly have prepared Bonds in     
	  certificated form registered in the names of the Beneficial Owners    
of Bonds shown on the records     
	  of the Participants provided to the Trustee, as of the date set forth    
in the notice described above.     
	  Bonds issued to the Beneficial Owners, or their designees, shall be    
in fully registered form     
	  substantially in the form set forth in Exhibit A.     
	      
	  	(f)	If any Securities Depository is replaced as the    
depository for the Bonds with another     
	  qualified Securities Depository, the Trustee, at the expense of the    
Company, will issue to the     
	  replacement Securities Depository Bonds substantially in the form    
set forth in Exhibit A, registered     
	  in the name of such replacement Securities Depository.     
	      
	  	(g)	The Issuer, the Company, the Tender Agent, the    
Remarketing Agent, and the Trustee     
	  shall have no liability for the failure of any Securities Depository to    
perform its obligation to any     
	  Participant, any Indirect Participant or any Beneficial Owner of any    
Bonds, and the Issuer, the     
	  Company, the Tender Agent, the Remarketing Agent, or the    
Trustee shall not be liable for the     
	  failure of any Participant, Indirect Participant, or other nominee of    
any Beneficial Owner of any     
	  Bonds to perform any obligation that such Participant, Indirect    
Participant, or other nominee may     
	  incur to any Beneficial Owner of the Bonds.     
	      
	  	(h)	Notwithstanding any other provision of this    
Indenture, on or prior to the date of     
	  issuance of the Bonds the Trustee, the Company, and the Issuer    
shall have executed and delivered     
	  to the initial Securities Depository a Letter of Representations    
governing various matters relating to                                          
	  the Securities Depository and its activities pertaining to the Bonds.     
The terms and provisions of such     
	  Letter of Representations are incorporated herein by reference and,    
in the event there shall exist any     
	  inconsistency between the substantive provisions of the said Letter    
of Representations and any     
	  provisions of this Indenture, then, for as long as the initial    
Securities Depository shall serve with     
	  respect to the Bonds, the terms of the Letter of Representations    
shall govern.    
	      
	      
	  Article III    
	  Redemption of Bonds; Purchase and Remarketing of Bonds    
	      
	  	Section 3.01.  Optional Redemption.  The Bonds shall be    
subject to optional redemption only     
	  as follows:    
	      
	  	(a)	Weekly Rate Mode, CP Rate Mode, or Daily Rate    
Mode.  While the Bonds are in     
	  the Weekly Rate Mode or the Daily Rate Mode, the Bonds shall be    
subject to optional redemption,     
	  in whole or in part on any Business Day, and while the Bonds are    
in the CP Rate Mode the Bonds     
	  shall be subject to optional redemption in whole or in part on any    
Interest Payment Date, in all cases     
	  at the direction of the Company and with the Bank's consent if    
required by the Reimbursement     
	  Agreement, upon at least 40 days" prior written notice from the    
Company to the Trustee, the Bank,     
	  and the Remarketing Agent, at a redemption price equal to 100% of    
the aggregate principal amount     
	  of the Bonds to be redeemed, plus accrued interest thereon to the    
redemption date, without     
	  premium.    
	      
	  	(b)	Adjustable Rate Mode. While the Bonds are in the    
Adjustable Rate Mode, the Bonds     
	  shall be subject to optional redemption, after the dates specified in    
the table below, in whole or in     
	  part on any date at the direction of the Company and with the    
Bank's consent if required by the     
	  Reimbursement Agreement, upon at least 40 days" prior written    
notice from the Company to the     
	  Trustee, the Bank, and the Remarketing Agent, at the applicable    
redemption price (expressed as a     
	  percentage of the principal amount to be redeemed) set forth below,    
plus accrued interest thereon     
	  to the date of redemption:    
	      
	  Length of Currently Applicable Adjustable	Dates After Which    
Redemption Is    
	  Rate Period (expressed in whole years)	Allowed and    
Redemption Prices*    
	      
	  greater than 10 	after 10 years at 102%, declining by 1%    
	  	annually to 100%    
	      
	  less than or equal to 10 and greater than 7 	after 5 years at 102%,    
declining by 1%    
	  	annually to 100%    
	      
	  less than or equal to 7 and greater than 4 	after 3 years at 102%,    
declining by 1%    
	  	annually to 100%    
	      
	  less than or equal to 4 and greater than 2 	after 2 years at 102%,    
declining by 1%    
	  	annually to 100%    
	      
	  less than or equal to 2 	not callable    
[FN]	    
	  *measured from the start of the currently applicable Adjustable    
Rate Period    
	      
	  	The payment of any premium upon the optional redemption    
of Bonds shall be made solely     
	  from Available Moneys.     
	      
	  	Notwithstanding the foregoing, the Bonds when in an    
Adjustable Rate Period may be subject     
	  to optional redemption upon terms different than those set forth    
above if the Company delivers to     
	  the Trustee on or before the first day of such Adjustable Rate Period    
a certificate specifying different     
	  optional redemption dates or prices to be in effect during such    
period (or that the Bonds will not be     
	  subject to optional redemption during such Period) and an opinion    
of Bond Counsel to the effect that     
	  the adoption of such optional redemption provisions would not    
adversely affect the exclusion of     
	  interest on the Bonds from the federal gross income of the Owners    
thereof.    
	      
	  	(c)	Purchase in Lieu of Optional Redemption.  The    
Company shall have the option to     
	  cause the Bonds to be subject to mandatory tender and purchase    
pursuant to Section 2.04 hereof in     
	  lieu of an optional redemption of Bonds pursuant to Section 3.01(a)    
or (b) above.  Such option may     
	  be exercised by delivery by the Company to the Trustee and    
Remarketing Agent on or prior to the     
	  Business Day preceding the optional redemption date of a written    
notice specifying that the Bonds     
	  shall not be redeemed, but instead shall be subject to mandatory    
tender and purchase pursuant to     
	  Section 2.04 hereof.  Upon delivery of such notice, the Bonds shall    
not be redeemed but shall instead     
	  be subject to mandatory tender pursuant to Section 2.04 hereof at a    
tender price equal to the price     
	  at which the Bonds would have been redeemed on the date which    
would have been the optional     
	  redemption date.    
	      
	  	Section 3.02.  Extraordinary Optional Redemption.  While    
the Bonds are in the Adjustable     
	  Rate Mode or the CP Rate Mode, the Bonds are subject to    
extraordinary redemption in whole on     
	  any date at a redemption price equal to the principal amount of    
outstanding Bonds plus accrued     
	  interest to the redemption date, without premium, upon the exercise    
by the Company of its option     
	  to cause the Bonds to be redeemed as a result of the occurrence of    
any of the events described     
	  below:     
	      
	  	(1)	the Project has been damaged or destroyed to such    
an extent that, in the judgment of     
	  the Company, (i) it cannot be reasonably restored to substantially    
the condition thereof immediately     
	  preceding such damage or destruction, (ii) the Company is thereby    
prevented from carrying on normal     
	  operations at the Project for a period of nine or more consecutive    
months following such damage or     
	  destruction, or (iii) it would not be economically feasible for the    
Company to replace, repair, rebuild,     
	  or restore the same;    
	      
	  	(2)	title in and to, or the temporary use of, all or    
substantially all of the Project has been     
	  taken under the exercise of the power of eminent domain (or sold in    
lieu of such a taking) by any     
	  governmental authority, or person acting under governmental    
authority and such a taking or sale, in     
	  the judgment of the Company, may result in the Company being    
prevented thereby from carrying on     
	  normal operations at the Project for a period of nine or more    
consecutive months; or    
	      
	  	(3)	as a result of any changes in the Constitution of the    
State or the Constitution of the     
	  United States of America or by legislative or administrative action    
(whether State or federal) or by     
	  final decree, judgment, decision, or order of any court or    
administrative body (whether State or     
	  federal), the Agreement has become void or unenforceable or    
impossible of performance in     
	  accordance with the intent and purposes of the parties as expressed    
therein.     
	      
	  	To exercise its option to effect an extraordinary optional    
redemption, the Company must     
	  deliver to the Trustee written notice of the occurrence of any such    
event and of its election to cause     
	  the Bonds to be redeemed as a result thereof.  Such notice shall    
specify the redemption date which     
	  shall be at least 40 days after the date of delivery of such notice to    
the Trustee.    
	      
	  	Section 3.03.  Mandatory Redemption. The Bonds are    
subject to mandatory redemption in     
	  whole on the earliest redemption date for which timely notice of    
redemption can be given by the     
	  Trustee after the occurrence of a Determination of Taxability at a    
redemption price equal to the     
	  aggregate outstanding principal amount of the Bonds plus accrued    
interest thereon to the redemption     
	  date, without premium. The foregoing amount shall constitute the    
total amount required to be paid     
	  to the Owners as a result of the occurrence of a Determination of    
Taxability.     
	      
	  	Section 3.04.  Notice of Redemption.  (a)  At least 30 days    
prior to the date of any redemption     
	  of the Bonds, the Trustee shall cause notice of the call for    
redemption to be sent by first class mail,     
	  postage prepaid, to the Tender Agent, the Bank, the Remarketing    
Agent, the Company, the     
	  Guarantor, and the Owner of each Bond to be redeemed.  In    
addition, such notice shall also be given     
	  (at least two Business Days before the redemption notice described    
in the preceding sentence) by     
	  registered, certified, or overnight mail, to all registered securities    
depositories then in the business     
	  of holding substantial amounts of obligations of types comprising    
the Bonds and to one or more     
	  national information services that disseminate notices of    
redemption of obligations such as the Bonds.      
	  Neither the failure to give any such notice nor any defect in any    
notice so mailed shall affect the     
	  sufficiency or the validity of any proceedings for the redemption of    
the Bonds.     
	      
	  	(b)	The redemption notice shall identify the Bonds or    
portions thereof to be redeemed and     
	  shall state (l) the date of such notice and the redemption date, (2)    
the redemption price, (3) the     
	  original date of execution and delivery of the Bonds to be    
redeemed, (4) the rate of interest borne     
	  by the Bonds to be redeemed, (5) the date of maturity of the Bonds,    
(6) the numbers and CUSIP     
	  numbers of the Bonds to be redeemed, (7) that the redemption price    
of any Bond payable only upon     
	  the surrender of the Bond to be Trustee at its corporate trust office,    
(8) the address at which the     
	  Bonds must be surrendered, (9) that interest on the Bonds called for    
redemption ceases to accrue     
	  on the redemption date provided that on such date Available    
Moneys are on deposit in the Bond     
	  Fund sufficient to pay the redemption price of the Bonds in full,    
and (10) such additional descriptive     
	  information identifying the Bonds to be redeemed, including their    
interest rate and stated maturity     
	  date as may be deemed appropriate by the Trustee to effect the    
redemption.    
	      
	  	Any notice of optional redemption shall also state that the    
Company may elect that the Bonds     
	  be subject to mandatory tender and purchase in lieu of optional    
redemption at a tender price equal     
	  to the redemption price.  Any notice of optional redemption may    
also state (and shall state, if the     
	  Company shall so direct) that the redemption is conditioned on    
receipt of monies for such     
	  redemption by the Trustee on or prior to the redemption date; if    
such moneys are not received, the     
	  redemption of the Bonds for which notice was given shall not be    
made.    
	      
	  	Section 3.05.  Effect of Availability of Redemption Prices.     
If on any redemption date Available     
	  Moneys sufficient to pay in full the redemption price of the Bonds    
called for redemption have been     
	  deposited with the Trustee and shall be available to be utilized to    
pay the redemption price of such     
	  Bonds, such Bonds shall no longer be secured by or be deemed to    
be Outstanding under the     
	  provisions of this Indenture. Interest shall not continue to accrue on    
such Bonds after the redemption     
	  date. If Available Moneys shall not be on deposit on the redemption    
date, such Bonds or portions     
	  thereof shall continue to bear interest until paid at the same rate as    
they would have borne had they     
	  not been called for redemption.    
	      
	  	Section 3.06.  Partial Redemption.  (a)  Any partial    
redemption of Bonds shall be made only     
	  in Authorized Denominations. If fewer than all of the Bonds shall    
be called for redemption, the     
	  portion of Bonds to be redeemed shall be selected by lot by the    
Trustee from among all Outstanding     
	  Bonds; provided that the Trustee shall first select Pledged Bonds    
and Company Bonds for     
	  redemption.  Each Bond shall be considered separate Bonds in    
Authorized Denominations for     
	  purposes of selecting the Bonds to be redeemed. Subject to the    
provisions of the Bonds with respect     
	  to the Book-Entry System, if any Bond shall be called for    
redemption only in part, then the Owner     
	  of such Bond, upon surrender of such Bond to the Trustee for    
payment, shall be entitled to receive     
	  a new Bond or Bonds in the aggregate principal amount of the    
unredeemed balance of the principal     
	  amount of such Bond, without charge therefor.     
	      
	  	(b)	If the Owner of any Bond which is called for    
redemption only in part shall fail to     
	  present such Bond to the Trustee for payment and exchange as    
aforesaid, such Bond shall,     
	  nevertheless, become due and payable on the date fixed for    
redemption, to the extent called for     
	  redemption (and to that extent only) and to such extent such Bond    
shall no longer be deemed to be     
	  Outstanding for purposes of this Indenture.     
	      
	  	(c)	Notwithstanding the foregoing, if the Bonds are    
held in the Book-Entry System at the     
	  time of a partial redemption of the Bonds, beneficial Ownership    
interests in the series of Bonds shall     
	  be selected for redemption in accordance with the rules and    
procedures established by the Securities     
	  Depository.    
	      
	  	Section 3.07.  Purchase of Tendered Bonds.  (a)  In    
performing their duties hereunder, the     
	  Tender Agent and the Remarketing Agent shall act as an agent of    
the persons to whom purchased     
	  Bonds are to be delivered pursuant to Section 3.10, of persons    
tendering such Bonds and of the     
	  Company and shall not be considered to be purchasing Bonds for    
their own account and, in the     
	  absence of written notification from the Trustee to the contrary,    
shall be entitled to assume that any     
	  Bond tendered or deemed tendered to the Remarketing Agent or the    
Tender Agent for purchase     
	  is entitled under the Indenture to be so purchased. No acceptance of    
Bonds by the Tender Agent     
	  hereunder shall effect any merger or discharge of the indebtedness    
of the Issuer evidenced by the     
	  Bonds. The Tender Agent and the Remarketing Agent shall accept    
all Bonds properly tendered for     
	  purchase in accordance with the provisions of the Bonds and as set    
forth in this Indenture.     
	      
	  	(b)	During any period that no Book-Entry System for    
the Bonds is in effect, a Tender     
	  Agent shall be appointed as provided in Section 7.11 hereof.     
Immediately upon the effectiveness of     
	  such appointment, the Tender Agent shall establish a special trust    
fund designated as the "Grapevine     
	  Industrial Development Corporation Industrial Development    
Revenue Bonds (Trencor Jetco, Inc.     
	  Project), Series 1994--Purchase Fund" (the "Purchase Fund").    
The Tender Agent shall hold all Bonds     
	  delivered to it in trust for the exclusive benefit of the respective    
Owners of Bonds tendering such     
	  Bonds for sale until moneys representing the purchase price of such    
Bonds have been delivered to     
	  or for the account of such Owners of Bonds. The Tender Agent    
shall hold all moneys delivered to     
	  it for the purchase of Bonds in the Purchase Fund in trust, solely for    
the benefit of the persons     
	  delivering such moneys until the Bonds purchased with such    
moneys have been delivered to or for     
	  the account of such persons and thereafter solely for the benefit of    
the persons entitled to such     
	  moneys. Moneys held in the Purchase Fund shall not be invested.     
The Issuer and the Trustee hereby     
	  authorize and direct the Tender Agent to withdraw sufficient funds    
from the Purchase Fund to pay     
	  the purchase price of tendered Bonds as the same becomes due and    
payable, which authorization and     
	  direction the Tender Agent accepts.     
	      
	  	(c)	During any period the Bonds are held in a Book-   
Entry System, the purchase price of     
	  tendered Bonds, (i) if derived from the source described in Section    
3.09(a), shall be paid on the     
	  tender date by the Remarketing Agent from moneys received from    
the purchaser of the remarketed     
	  Bonds, (ii) if derived from either the source described in Section    
3.09(b) or 3.09(c) shall be paid on     
	  the tender date by the Trustee from moneys drawn on the Letter of    
Credit or received from the     
	  Company, as the case may be, and (iii) moneys paid by the    
Guarantor pursuant to Section 2.1(c) of     
	  the Guaranty.    
	      
	  	Section 3.08.  Remarketing of Tendered Bonds; Payment of    
Purchase Price.  (a)  The     
	  Remarketing Agent shall use its best efforts to remarket tendered    
Bonds of which it has received     
	  notice of tender from the Tender Agent (or Beneficial Owners, as    
the case may be), at a price equal     
	  to 100% of the principal amount thereof plus, accrued interest to    
the purchase date.  Such     
	  remarketing shall be made in accordance with, and subject to the    
conditions of, the provisions of the     
	  Remarketing Agreement.  Bonds which have been duly tendered for    
purchase and which have not     
	  been remarketed shall be purchased on the tender date with the    
proceeds of an appropriate draw     
	  under the Letter of Credit; provided, however, (i) during any period    
the Bonds are not secured by     
	  a Letter of Credit, or (ii) if the Bank shall fail to honor a draw on    
the Letter of Credit to provide     
	  for the purchase price of tendered Bonds, then such Bonds will be    
purchased by the Company on the     
	  tender date.    
	       
	  	(b)	Upon receipt of a duly tendered written notice of    
an optional tender of Bonds, the     
	  Tender Agent shall notify the Remarketing Agent, the Company,    
the Guarantor, and the Trustee of     
	  the principal amount of Bonds tendered and the date fixed for    
purchase of the tendered Bonds.      
	  During any period the Bonds are in the Book-Entry System, such    
notice will be given by the     
	  Remarketing Agent to the Company and the Trustee.    
	      
	  	(c)	Prior to 4:00 p.m. on the Business Day which    
immediately precedes the purchase date     
	  for any Bonds (or, in the case of Bonds in the Daily Rate Mode,    
prior to 11:30 a.m. on the purchase     
	  date of such Bonds), the Remarketing Agent shall give notice to the    
Tender Agent, the Company,     
	  the Guarantor, and the Trustee of the principal amount of such    
Bonds which have been remarketed,     
	  the names, addresses, and taxpayer identification numbers of the    
purchasers of such Bonds and the     
	  denominations in which the Bonds are to be purchased by and    
delivered to each purchaser. If less     
	  than all of the Bonds to be tendered on such purchase date have    
been remarketed, the Remarketing     
	  Agent shall, in addition, notify the Trustee, the Tender Agent, the    
Guarantor, and the Company prior     
	  to 10:30 a.m. (or, in the case of Bonds in the Daily Rate Mode,    
11:30 a.m.) on the purchase date of     
	  the principal amount of Bonds which have not been remarketed and    
the amount of accrued interest     
	  to be paid on such Bonds on such purchase date. Purchasers of    
Bonds which have been remarketed     
	  shall be required to deliver the purchase price thereof directly to the    
Tender Agent for deposit in     
	  the Purchase Fund (or, during any period the Bonds are in the    
Book-Entry System, such moneys shall     
	  be transferred to the account of the Remarketing Agent on the    
records of the Securities Depository)     
	  not later than 10:30 a.m. (or, in the case of Bonds in the Daily Rate    
Mode, 11:30 a.m.), on the     
	  purchase date.  By 11:30 a.m., on the purchase date, the Tender    
Agent shall notify (promptly     
	  confirmed in writing) the Trustee, the Remarketing Agent, the    
Company, the Guarantor, and the     
	  Bank of the amount of remarketing proceeds which have been    
deposited.  During any period the     
	  Bonds are in the Book-Entry System, such notice shall be given by    
the Remarketing Agent.     
	      
	  	(d)	Prior to 12:00 noon, on any purchase date (whether    
optional or mandatory), the Trustee     
	  shall draw upon the Letter of Credit, in an amount equal to the    
purchase price of all Bonds to be     
	  purchased on such purchase date, less the amount of remarketing    
proceeds of which the Trustee has     
	  notice were deposited with the Tender Agent (or the Remarketing    
Agent during any period the     
	  Bonds are in the Book-Entry System) by 11:30 a.m., on such date.     
In the event of a draw on the     
	  Letter of Credit upon a mandatory tender due to a substitution of an    
Alternate Credit Facility, the     
	  draw shall be made upon the Letter of Credit being replaced.  If the    
Bonds are not then secured by     
	  a Letter of Credit, by 1:30 p.m. on the purchase date for any Bonds,    
the Tender Agent (or the     
	  Trustee during any period the Bonds are in the Book-Entry System)    
shall receive from the Company,     
	  pursuant to Section 5.1(b) of the Agreement, an amount equal to    
the purchase price of all Bonds to     
	  be purchased on such date, less the amount of remarketing proceeds    
of which the Trustee has notice     
	  were on deposit with the Tender Agent or the Remarketing Agent,    
as the case may be, by 11:30 a.m.     
	  on such date. No draw on the Letter of Credit shall be made with    
respect to Pledged Bonds or     
	  Company Bonds.     
	      
	  	(e)	The Trustee shall, to the extent it has drawn    
moneys under the Letter of Credit for the     
	  purchase of Bonds, authorize direct payment by the Bank to the    
Tender Agent (or, during any period     
	  the Bonds are in the Book-Entry System, to the payee specified by    
the Securities Depository) of the     
	  moneys so drawn.     
	      
	  	(f)	Notices pursuant to this Section shall be by    
telephone, tested telecopy (receipt     
	  confirmed by telephone), telefacsimile transmittal, or telegram,    
promptly confirmed in writing, except     
	  that any drawing under the Letter of Credit shall be in accordance    
with the terms thereof.     
	       
	  	(g)	Anything in this Indenture to the contrary    
notwithstanding, there shall be no obligation     
	  on the part of the Remarketing Agent to remarket Bonds (i) if there    
shall have occurred and be     
	  continuing an Event of Default under this Indenture or a    
Determination of Taxability, or (ii) which     
	  are subject to mandatory tender hereunder, except as the    
Remarketing Agent and the Company have     
	  otherwise agreed in the Offering Agreement.    
	      
	  	(h)	Any Bond optionally tendered for purchase after    
the date on which such Bond has been     
	  selected for redemption or the Trustee has notified the Owners of    
pendency of a conversion of the     
	  interest rate Mode of the Bonds shall not be remarketed unless the    
purchaser has been notified by     
	  the Trustee of the redemption or the interest rate Mode conversion,    
as appropriate.  Any purchaser     
	  so notified must deliver a notice to the Trustee and the Tender    
Agent (or, during any period the     
	  Bonds are in the Book-Entry System, to the Remarketing Agent)    
stating that such purchaser is aware     
	  of the pendency of the redemption or of the interest rate Mode    
conversion, as appropriate, and     
	  agreeing not to resell the Bonds prior to the date of such    
redemption or conversion, as the case may     
	  be.     
	      
	  	Section 3.09.  Funds for Purchase Price of Bonds.  On the    
date Bonds are to be purchased     
	  pursuant to the optional or mandatory tender provisions of this    
Indenture, the Tender Agent shall     
	  deliver the purchase price to the tendering Owner (or, if the Bonds    
are in a Book-Entry System, the     
	  Remarketing Agent or the Trustee, as appropriate, shall deliver the    
purchase price to the appropriate     
	  payee on the records of the Securities Depository), but only from    
the funds listed below, in the order     
	  of priority indicated:     
	      
	  	(a)	the proceeds of the sale of such Bonds which have    
been remarketed by the     
	  Remarketing Agent to any person other than the Company, the    
Guarantor, or the Issuer (or any     
	  "insider" of the Company, the Guarantor, or the Issuer within the    
meaning of the Bankruptcy Code)     
	  which have been delivered to the Tender Agent or the Remarketing    
Agent by 11:30 a.m., on the     
	  purchase date;    
	      
	  	(b)	moneys drawn under the Letter of Credit;    
	      
	  	(c)	moneys deposited by the Company with the Trustee    
pursuant to the Agreement; and     
	      
	  	(d)	moneys paid by the Guarantor pursuant to Section    
2.1(c) of the Guaranty.    
	      
	  	Section 3.10.  Delivery of Purchased Bonds.  The Tender    
Agent shall make available by 4:00     
	  p.m. on the purchase date of any tendered Bonds (whether such    
tender was optional or mandatory),     
	  at its principal office in New York City, Bonds which have been    
purchased with moneys described     
	  in Section 3.09(a) for receipt by the purchaser thereof, which Bonds    
shall be authenticated by the     
	  Tender Agent.  Bonds purchased with moneys described in Section    
3.09(a) shall be registered in the     
	  manner directed by the Remarketing Agent and delivered to the    
Remarketing Agent for redelivery     
	  to the purchasers thereof.  Bonds purchased with moneys described    
in Section 3.09(b) shall be     
	  delivered by the Tender Agent to the Trustee, and registered by the    
Trustee in the name of the     
	  Company indicating their status as Pledged Bonds (or if the Bonds    
are held in the Book-Entry     
	  System, such Bonds shall be recorded in the books of the Securities    
Depository for the account of     
	  the Trustee and shall be deemed to be pledged to the Bank).  Bonds    
purchased with moneys     
	  described in Section 3.09(c) shall be registered in the name of the    
Company and delivered to the     
	  Company.  Bonds, purchased with moneys described in Section    
3.09(d) hereof shall be registered in     
	  the name of the Guarantor and delivered to the Guarantor.    
	       
	  	Notwithstanding anything herein to the contrary, so long as    
the Bonds are held under the     
	  Book-Entry System, Bonds will not be delivered as set forth in the    
preceding paragraph; rather,     
	  transfers of beneficial ownership of the Bonds to the persons    
indicated above will be effected     
	  pursuant to its rules and procedures established by the Securities    
Depository.    
	      
	  	Section 3.11.  Pledged Bonds.  If any Bond is purchased    
pursuant to Section 3.07 hereof with     
	  moneys drawn under the Letter of Credit pursuant to Section    
3.09(b) hereof, if no Book-Entry     
	  System is then in effect, that Bond shall be delivered to and held by    
the Trustee, registered in the     
	  name of the Company and shall constitute a Pledged Bond until    
released as herein provided. A     
	  Pledged Bond so held by the Trustee shall be released only upon    
receipt by the Trustee or the Bank     
	  of an amount equal to the principal amount thereof plus accrued    
interest, if any, thereon to the date     
	  of purchase and receipt by the Trustee of written confirmation of    
the reinstatement of the amounts     
	  available to be drawn under the Letter of Credit to cover the full    
principal amount of all Outstanding     
	  Bonds, plus Adequate Interest Coverage.  If a Book-Entry System is    
then in effect, Bonds purchased     
	  with Letter of Credit proceeds pursuant to Section 3.09(b) hereof    
shall be reflected on the records     
	  of the Securities Depository as being held for the account of the    
Trustee, and the Trustee agrees that     
	  it shall hold such Bonds solely for the benefit of the Bank.  While a    
Book-Entry System is in effect,     
	  the Trustee shall cause the release of such Bonds from its account    
on the records of the Securities     
	  Depository only under the conditions for release of Pledged Bonds    
previously set forth in this     
	  paragraph.    
	      
	  	During the Daily Rate Period, CP Rate Period, and the    
Weekly Rate Period, the Remarketing     
	  Agent shall use its best efforts to remarket Pledged Bonds in    
accordance with the provisions of the     
	  Offering Agreement.  If the Remarketing Agent remarkets any    
Pledged Bond, the Remarketing     
	  Agent shall give the notice described in the first sentence of Section    
3.08(c) hereof, and shall direct     
	  the purchaser of such Pledged Bond to transfer, by 10:00 a.m. (or,    
in the case of Bonds in the Daily     
	  Rate Mode, 11:30 a.m.) on the purchase date, the purchase price of    
such remarketed Pledged Bond     
	  to the Bank, with notice thereof to the Company and the Trustee.     
The Remarketing Agent shall     
	  deliver remarketed Pledged Bonds to the purchasers thereof in    
accordance with Section 3.10 hereof.    
	      
	  	On each Interest Payment Date prior to the release of    
Pledged Bonds, the Trustee shall apply     
	  moneys in the Non-Available Moneys Account of the Bond Fund to    
the payment of principal of and     
	  interest on such Pledged Bonds, but shall not draw on the Letter of    
Credit or use moneys in the     
	  Letter of Credit Account of the Bond Fund for such purpose to any    
extent whatsoever; and the     
	  Trustee shall receive for the account of the Bank the interest and    
principal paid in respect of such     
	  Pledged Bonds, and immediately upon such receipt the Trustee    
shall pay such interest and principal     
	  over to the Bank pursuant to written wire transfer instructions    
acceptable to the Trustee; provided,     
	  however, that if at such time the Trustee has been notified in    
writing by the Bank that there shall     
	  not remain any amount owed to the Bank under the Reimbursement    
Agreement, such interest and     
	  principal payments shall be paid over to the Company.     
	      
	  	It is recognized and agreed by the Trustee that while it    
holds Pledged Bonds, such Pledged     
	  Bonds are held by the Trustee for the benefit of the Bank as a first    
priority secured creditor.    
	      
	  	Notwithstanding anything herein to the contrary, so long as    
the Bonds are held under the     
	  Book-Entry System, Pledged Bonds shall not be delivered to and    
held by the Trustee; rather transfers     
	  of beneficial Ownership of Bonds to the persons indicated above    
will be effected pursuant to the     
	  rules and procedures established by the Securities Depository.    
	      
	       
	  Article IV    
	  General Provisions    
	      
	  	Section 4.01.  Payment of Principal, Premium, if any, and    
Interest.  The Issuer covenants that     
	  it will duly and punctually pay or cause to be paid the principal of,    
premium, if any, and interest on     
	  the Bonds issued under this Indenture at the place, on the dates,    
and in the manner provided herein     
	  and therein according to the true intent and meaning hereof and    
thereof, but solely from the     
	  payments, revenues, and receipts specifically assigned herein for    
such purposes as set forth in     
	  Section 5.01 of this Indenture.     
	      
	  	Section 4.02.  Instruments of Further Assurance.  (a)  The    
Issuer covenants that it will, at the     
	  expense of the Company, execute and deliver such indentures    
supplemental hereto and such further     
	  acts, instruments, and transfers as the Trustee or the Bank    
reasonably may require for the better and     
	  more effectual assignment to the Trustee of all payments, revenues,    
and other amounts payable under     
	  or with respect to the Agreement, the Letter of Credit, and any    
other income and other moneys     
	  assigned hereby to the payment of the principal of, premium, if any,    
and interest on the Bonds.  The     
	  Issuer further covenants that it will not create or, to its knowledge,    
suffer to be created any lien,     
	  encumbrance, or charge upon its interest in the revenues and other    
amounts payable under or with     
	  respect to the Trust Estate, except the lien and charge granted    
hereby.     
	      
	  	(b)	The Trustee agrees that it will, at the expense of    
the Company pursuant to the     
	  Agreement, cause the Company to record and file financing    
statements and all supplements thereto,     
	  and such other instruments (including, but not limited to,    
continuation statements) as may be required     
	  from time to time by the Issuer, the Bank, the Guarantor, or the    
Company to be recorded or filed,     
	  in such manner and at such places as from time to time may be    
required by law in order fully to     
	  preserve and protect the security of the Owners of the Bonds and    
the Bank, and the rights of the     
	  Trustee hereunder.     
	      
	  	Section 4.03. Tax-Exempt Status of Bonds.  The Issuer and    
the Trustee each covenant to     
	  commit or suffer no act within their control that would alter the    
status or character of the Bonds, or     
	  the interest to be paid on the Bonds, for purposes of Federal income    
taxation.  The provisions of this     
	  Section shall apply to the Trustee only to the extent that the Trustee    
is acting hereunder in its sole     
	  discretion.  Toward that end, the Issuer and the Trustee agree that    
they will comply with and take     
	  all actions required by the Tax Agreement.     
	      
	  	Section 4.04.  Books, Records and Accounts.  The Trustee    
agrees to keep proper books for     
	  the registration of, and transfer of Ownership of, each Bond, and    
proper books, records, and accounts     
	  in which complete and correct entries shall be made of all    
transactions relating to the receipt,     
	  disbursement, investment, allocation, and application of the    
proceeds received from the sale of the     
	  Bonds, the revenues received from the Agreement, the documents    
executed by the Company in     
	  connection therewith, the Letter of Credit, the funds and accounts    
created pursuant to this Indenture,     
	  and all other moneys held by the Trustee under.  The Trustee shall,    
during regular business hours     
	  and upon reasonable prior written notice, make such books,    
records, and accounts available for     
	  inspection by the Issuer, the Company, the Bank, and the    
Guarantor.  The Trustee shall also make     
	  such books, records, and account available for inspection by the    
Bond Owners, but subject to the     
	  following limitations:    
	      
	  	(a)	the Bond Owner provides the Trustee with at least    
five (5) Business Days' prior written     
	  notice of the proposed inspection;    
	       
	  	(b)	such notice specifies what the Bond Owner wishes    
to inspect and when the inspection     
	  is to take place;    
	      
	  	(c)	no documents other than those executed on the    
Closing Date in connection with the     
	  issuance and sale of the Bonds or documents which have been    
recorded or otherwise made a part     
	  of a public record will be made available for inspection;    
	      
	  	(d)	the Bond Owner provides evidence satisfactory to    
the Trustee of registered or beneficial     
	  ownership of Bonds;    
	      
	  	(e)	the scope of the proposed inspection is reasonably    
satisfactory to the Trustee; and    
	      
	  	(f)	no copies of documents are made of the Trustee's    
records, other than a copy of the

	  Industrial Development Corporation Industrial Development    
Revenue Bonds (Trencor Jetco, Inc.     
	  Project) Series 1994"Bond Proceeds Fund" (the "Bond Proceeds    
Fund").  The Bond Proceeds Fund     
	  shall have a Project Account and a Cost of Issuance Account.  The    
proceeds of the sale of the Bonds     
	  upon initial issuance thereof shall be deposited by the Trustee on    
the Closing Date in the Accounts     
	  in the Bond Proceeds Fund as directed by a certificate of the    
Company.  Moneys held in the Costs     
	  of Issuance Account shall be disbursed as set forth in such    
certificate of the Company.  Moneys held     
	  in the Project Account shall be disbursed pursuant to Requisitions,    
a form of which is set forth at     
	  Section 5.11 hereof.  Moneys, if any, remaining in the Bond    
Proceeds Fund on the Completion Date     
	  and any moneys in the Bond Proceeds Fund on the date the    
Company prepays all amounts, payable     
	  under Section 5.1(a) of the Agreement shall be transferred on such    
date to the Available Moneys     
	  Account of the Bond Fund to be applied as provided in Section 5.02    
hereof.    
	      
	  	Section 5.02.  Bond Fund.  There is hereby created by the    
Issuer and ordered established with     
	  the Trustee a trust fund to be designated the "Grapevine Industrial    
Development Corporation     
	  Industrial Development Revenue Bonds (Trencor Jetco, Inc.    
Project), Series 1994"Bond Fund" (the     
	  "Bond Fund").  Within the Bond Fund there are hereby created    
by the Issuer and ordered     
	  established with the Trustee three separate and segregated trust    
accounts to be designated,     
	  respectively, (a) the "Available Moneys Account," (b) the "Non-   
Available Moneys Account", and (c)     
	  the "Letter of Credit Account".     
	       
	  	There shall be deposited into the Bond Fund when received:    
(a) all payments specified in     
	  Section 5.1 of the Agreement or Section 2.1(a) or (b) of the    
Guaranty; (b) all moneys required to     
	  be so deposited in connection with any redemption of Bonds; (c) all    
moneys drawn by the Trustee     
	  under the Letter of Credit to pay interest, premium, if any, principal    
or the redemption price of any     
	  Bonds; (d) any amounts directed to be transferred into the Bond    
Fund pursuant to any provision of     
	  this Indenture; and (e) all other moneys when received by the    
Trustee which are required to be     
	  deposited into the Bond Fund or which are accompanied by    
directions that such moneys are to be     
	  paid into the Bond Fund.  Any amounts paid to the Trustee which    
do not constitute Available     
	  Moneys shall be held in the Non-Available Moneys Account and    
shall not be commingled with any     
	  other moneys held by the Trustee.  At such time as moneys in the    
Non-Available Moneys Account     
	  shall constitute Available Moneys, they shall be transferred to the    
Available Moneys Account.  Any     
	  amounts drawn under the Letter of Credit shall be held in the Letter    
of Credit Account and shall     
	  not be commingled with any other moneys held by the Trustee.     
Any amounts received for deposit     
	  in the Bond Fund which constitute Available Moneys (other than    
amounts drawn under the Letter     
	  of Credit), and any amounts deposited in the Non-Available    
Moneys Account which at a later date     
	  become Available Moneys, shall be held in the Available Moneys    
Account and shall not be     
	  commingled with any other moneys held by the Trustee.     
	      
	  	Section 5.03.  Letter of Credit; Alternate Credit Facility.  (a)     
Initial Letter of Credit.  The     
	  Initial Letter of Credit shall be delivered to the Trustee    
simultaneously with the original issuance and     
	  delivery of the Bonds.    
	      
	  	(b)	Alternate Credit Facility.  The Company may at    
any time substitute an Alternate Credit     
	  Facility for an existing Letter of Credit, subject to the limitations    
set forth in this Article V.  An     
	  Alternate Credit Facility shall be an irrevocable letter of credit,    
bank bond purchase agreement, bond     
	  insurance policy, revolving credit agreement, surety bond, or other    
agreement or instrument under     
	  which any person or entity (other than the Issuer or the Company)    
undertakes to make or provide     
	  funds to make payments of the principal and purchase price of, and    
interest on, the Bonds, as and     
	  when due, provided that the Alternate Credit Facility must be    
effective as of a date on or prior to     
	  the date of expiration of the then existing Letter of Credit and must    
provide coverage in an amount     
	  at least equal to the sum of (A) the aggregate principal amount of    
Bonds (other than Pledged Bonds     
	  or Company Bonds) at the time Outstanding, plus (B) Adequate    
Interest Coverage.     
	      
	  	Pursuant to Section 2.04 of this Indenture, if an Alternate    
Credit Facility is furnished, the     
	  Bonds shall be subject to mandatory tender unless the Company    
furnishes the Trustee by the 25th     
	  day prior to the scheduled Letter of Credit expiration or termination    
date written evidence from each     
	  Rating Agency having a rating in effect for the Bonds that the    
Rating Agency has reviewed the     
	  proposed Alternate Credit Facility and that its replacement of the    
current Letter of Credit will not     
	  by itself result in a withdrawal or reduction of the Rating    
Agency"s current rating for the Bonds (a     
	  "Maintenance of Rating").  Notwithstanding the foregoing, when    
the Bonds are in the CP Rate Mode     
	  or an Adjustable Rate Mode, an existing Letter of Credit may not be    
replaced prior to the expiration     
	  date of the then applicable Rate Period with an Alternate Credit    
Facility unless either (a) the Trustee     
	  is furnished with evidence of a Maintenance of Rating by the date    
described above (in which case     
	  the Bonds will not be subject to mandatory tender as a result    
thereof) or (b) in the event evidence     
	  of Maintenance of Rating is not received, the substitution occurs on    
a date on or after which the     
	  Bonds may be optionally redeemed pursuant to the Indenture and    
the mandatory tender price     
	  payable upon the mandatory tender of Bonds as a result of such    
substitution includes a premium     
	  equal to the redemption premium at that time payable pursuant to    
the optional redemption provisions     
	  of this Indenture.    
	       
	  	The Company shall notify the Trustee of its intention to    
deliver an Alternate Credit Facility     
	  at least 25 days prior to the date of such delivery.  Upon receipt of    
such notice, the Trustee will     
	  promptly mail a notice of the anticipated delivery of the Alternate    
Credit Facility by first class mail     
	  to the Issuer, the Remarketing Agent, and each Owner at the    
Owner"s registered address.    
	      
	  	On or prior to the delivery of any Alternate Credit Facility    
to the Trustee, the Company shall     
	  furnish to the Trustee (i) a written opinion of counsel acceptable to    
the Trustee stating that delivery     
	  of such Alternate Credit Facility to the Trustee is authorized under    
the Agreement and the     
	  Indenture, and complies with the terms hereof and thereof, and (ii)    
an opinion of counsel to the     
	  issuer of such Alternate Credit Facility to the effect that the    
Alternate Credit Facility is a valid and     
	  binding obligation of the issuer thereof, enforceable in accordance    
with its terms, subject to usual     
	  exceptions relating to bankruptcy and insolvency.  In addition, if    
the Alternate Credit Facility is issued     
	  in connection with a conversion of the interest rate Mode on the    
Bonds or if the Company grants     
	  a security interest in any cash, securities, or investment type    
property to the issuer or provider of the     
	  Alternate Credit Facility, the Company must furnish the Trustee an    
opinion of Bond Counsel stating     
	  that such grant will not adversely affect the exemption of interest    
on the Bonds from Federal income     
	  taxation.    
	      
	  	(c)	Surrender of Letter of Credit.  If at any time there    
shall have been delivered to the     
	  Trustee an Alternate Credit Facility, together with the other    
documents and opinions required by this     
	  Article V, then the Trustee shall accept such Alternate Credit    
Facility and promptly surrender the     
	  previously held Letter of Credit to the issuer thereof, in accordance    
with the terms thereof for     
	  cancellation.  If at any time there shall cease to be any Bonds    
Outstanding under this Indenture, or     
	  the Bonds are deemed paid under Section 10.01 of this Indenture,    
or if the Letter of Credit expires     
	  in accordance with its terms, the Trustee shall promptly surrender    
the Letter of Credit to the issuer     
	  thereof, in accordance with the terms thereof, for cancellation.  The    
Trustee shall comply with the     
	  procedures set forth in the Letter of Credit relating to the    
termination thereof.    
	      
	  	(d)	Federal Income Tax Requirements Pertaining to    
Substitutions of Letters of Credit     
	  Upon Certain Mode Conversions.  The CP Rate Mode, the Daily    
Rate Mode, the Weekly Rate     
	  Mode, and each Adjustable Rate Period of one year or less shall be    
referred to as a "Short-Term     
	  Mode" and each Adjustable Rate Period of greater than one    
year"s duration shall be referred to as     
	  a "Long-Term Mode."  Upon any conversion or change from a    
Short-Term Mode to a Long-Term     
	  Mode or from a Long-Term Mode to a Short-Term Mode, if the    
Company then proposes to either     
	  (i) add a Letter of Credit where none was then in effect, (ii)    
terminate a Letter of Credit then in     
	  effect without replacing it with an Alternate Credit Facility, or (iii)    
terminate an existing Letter of     
	  Credit and substitute an Alternate Credit Facility issued by a    
different Bank, the following shall apply:    
	      
	      	(A)	If the change or conversion is from a Long-Term    
Mode to a Short-Term Mode,     
	      the Bonds shall be supported by a Letter of Credit issued by an    
entity with the highest generic     
	      (i.e., without regard to "+" or "-" symbols) short-term rating    
on the effective date of such     
	      change or conversion by the Rating Agency then rating the    
Bonds.    
	      
	      	(B)	If the change or conversion is from a Short-Term    
Mode to an Adjustable Rate     
	      Period of greater than or equal to one but less than three years"    
duration, the Bonds shall be     
	      supported by a Letter of Credit issued by an entity with an "A"    
long-term rating (or its     
	      equivalent) on the effective date of such change or conversion by    
the Rating Agency than     
	      rating the Bonds.     
	       
	      	(C)	If the change or conversion is from a Short-Term    
Mode to an Adjustable Rate     
	      Period of greater than or equal to three years" duration, the    
Bonds shall not be supported by     
	      any Letter of Credit for at least the duration of the Adjustable    
Rate Period to which the     
	      Bonds are being converted.     
	      
	  	Notwithstanding any of the foregoing provisions of this    
Section 5.03(d), the Bonds may or may     
	  not be supported by a Letter of Credit in contravention of such    
provisions if there is delivered to the     
	  Trustee prior to the date of any such change or conversion an    
opinion of Bond Counsel to the effect     
	  that the deviation from the provisions of this Section 5.03(d) will    
not adversely affect the exclusion     
	  from gross income of interest on the Bonds.    
	      
	  	Section 5.04.  Letter of Credit Draws and Bond Fund    
Moneys to Pay Principal, Premium, or     
	  Interest.  (a) On or before each Interest Payment Date, redemption    
date, and date on which principal     
	  shall be due and payable on the Bonds, whether at maturity or upon    
acceleration, the Trustee shall     
	  draw under the Letter of Credit (if then in effect) an amount which    
shall be sufficient for the     
	  purpose of paying the principal of, premium, if any (if the Letter of    
Credit then covers premium) and     
	  interest due and payable on the Bonds (other than Pledged Bonds    
and Company Bonds) on such     
	  date.  Such drawing shall be made in a timely manner under the    
terms of the Letter of Credit in     
	  order that the Trustee may realize funds thereunder in sufficient    
time to pay Owners on the payment     
	  date as provided herein.  All amounts derived by the Trustee with    
respect to the Letter of Credit     
	  shall be deposited in the Letter of Credit Account of the Bond Fund    
upon receipt thereof by the     
	  Trustee, as provided in Section 5.03.  If no Letter of Credit is then    
in effect, by 11:00 a.m. on any     
	  Interest Payment Date, redemption date, acceleration date, or the    
maturity date of the Bonds, as the     
	  case may be, the Trustee shall receive from the Company pursuant    
to Section 5.1(a) of the     
	  Agreement the full amount of principal of, premium, if any, and    
interest due on the Bonds on that     
	  date.    
	      
	  	(b)	The Issuer hereby authorizes and directs the    
Trustee to withdraw sufficient funds from     
	  the Letter of Credit Account of the Bond Fund to pay the principal    
of, premium, if any, and interest     
	  on, the Bonds as the same become due and payable; and, in the    
event of a default under the Letter     
	  of Credit, or at such time as no Letter of Credit secures the Bonds,    
to use all moneys then on     
	  deposit, first in the Available Moneys Account and thereafter the    
Non-Available Moneys Account,     
	  of the Bond Fund to pay principal of, premium, if any, and interest    
on, the Bonds, which     
	  authorization and direction the Trustee hereby accepts.  On the    
Business Day which next succeeds     
	  any date on which moneys are to be disbursed from the Bond Fund    
pursuant to the preceding     
	  sentence, if moneys then remain in the Bond Fund, and if the    
Trustee's fees and expenses have been     
	  paid such moneys shall be disbursed to the Bank to the extent    
amounts are then owed to the Bank     
	  pursuant to the Reimbursement Agreement.  The Trustee may rely    
on a certificate from the Bank     
	  which certifies the amounts owed under the Reimbursement    
Agreement at any time.    
	      
	  	Section 5.05.  Investment of Moneys.  Subject to the    
restrictions hereinafter set forth in this     
	  Section 5.05 and in the Tax Agreement, any moneys held in the    
Non-Available Moneys Account of     
	  the Bond Fund and the Bond Proceeds Fund shall be invested and    
reinvested by the Trustee upon     
	  the written instructions of the Company in Qualified Investments,    
maturing no later than the date     
	  on which it is estimated that such moneys will be required to be    
paid out hereunder.  Moneys held     
	  in the Available Moneys Account of the Bond Fund shall be    
invested and reinvested solely in     
	  Government Obligations, maturing no later than the date on which    
such moneys will be required to     
	  be paid out hereunder.  Moneys held in the Purchase Fund and the    
Letter of Credit Account and     
	  moneys held pursuant to Section 5.06 hereof shall not be invested.     
The Trustee may make any and     
	  all such investments through its own investment department, or    
through any of its affiliates or     
	  subsidiaries.  The Trustee shall be entitled to rely on all written    
investment instructions or telephonic     
	  instructions subsequently confirmed in writing provided by the    
Company hereunder, and shall have     
	  no duty to monitor the compliance thereof with the restrictions set    
forth in this Section 5.05 or in     
	  the Tax Agreement.  The Trustee shall not be responsible or liable    
for the performance of any such     
	  investments or for keeping the moneys held by it hereunder fully    
invested at all times other than in     
	  accordance with the instructions of the Company.  Absent the    
provision of investment instructions     
	  hereunder, the Trustee shall not make any investment of the    
moneys held pursuant hereto; provided,     
	  however, that the Trustee shall notify the Company in the event any    
moneys are being held     
	  uninvested pursuant hereto.  Any obligations acquired by the    
Trustee as a result of such investment     
	  or reinvestment shall be held by or under the control of the Trustee    
and shall be deemed to     
	  constitute a part of the Fund or Account from which the moneys    
used for its purchase were taken.      
	  All investment income shall be retained in the Fund or Account to    
which the investment is credited     
	  from which such income is derived.    
	      
	  	Section 5.06.  Moneys to Be Held in Trust; Nonpresentment    
of Bonds.  (a)   All moneys     
	  required to be deposited with or paid to the Trustee for the account    
of any Fund or Account under     
	  any provisions of this Indenture shall be held by the Trustee in    
trust, and, except for moneys     
	  deposited with or paid to the Trustee for redemption of Bonds,    
notice of the redemption for which     
	  has been duly given, and moneys on deposit in the Rebate Fund,    
shall, while held by the Trustee,     
	  constitute part of the Trust Estate and be subject to the security    
interest created hereby.     
	      
	  	(b)	In the event any Bond shall not be presented for    
payment when the principal thereof     
	  becomes due, either at maturity or otherwise, or at the date fixed for    
redemption thereof, if Available     
	  Moneys sufficient to pay such Bond shall have been deposited in    
the Bond Fund, all liability of the     
	  Issuer to the Owner thereof for the payment of such Bond shall    
forthwith cease, determine, and be     
	  completely discharged, and thereupon it shall be the duty of the    
Trustee, subject to applicable escheat     
	  laws, to hold such moneys, without liability for interest thereon, for    
the benefit of the Owner of such     
	  Bond who shall thereafter be restricted exclusively to such moneys,    
for any claim of whatever nature     
	  on his part under this Indenture or on, or with respect to, said    
Bond.  Such moneys shall be held in     
	  a separate and segregated fund and shall not be invested.     
	      
	  	(c)	Any moneys so deposited with and held by the    
Trustee not so applied to the payment     
	  of Bonds for at least two years after the date on which the same    
shall have become due shall upon     
	  (i) payment of the Trustee's fees and expenses and (ii) delivery to    
the Trustee of indemnification     
	  reasonably satisfactory to it, then be paid by the Trustee to the    
Bank, upon the written direction of     
	  the Bank that amounts are due and owing the Bank under the    
Reimbursement Agreement, or in any     
	  other event, to the Company upon the written direction of the    
Company.  Thereafter Owners shall     
	  be entitled to look only to the Company for payment, the Company    
shall not be liable for any interest     
	  thereon and shall not be regarded as a trustee of such moneys and    
the Trustee shall have no further     
	  responsibilities with respect to such moneys.     
	      
	  	(d)	The obligation of the Trustee under this Section to    
pay any such funds to the Company     
	  shall be subject, however, to any provisions of law applicable to the    
Trustee or to such funds     
	  providing other requirements for disposition of unclaimed property.     
	      
	  	Section 5.07.  Repayment from Indenture Funds.  Any    
amounts remaining in any Fund or     
	  Account created under this Indenture, after payment or provision    
for payment in full of the Bonds     
	  in accordance with Article X hereof, the fees, charges, and    
expenses of the Issuer, the Trustee, the     
	  Tender Agent, the Remarketing Agent, and any co-trustee    
appointed hereunder, and all other     
	  amounts required to be paid hereunder or under the Agreement,    
and after and to the extent that the     
	  Company shall determine that the payment of such remaining    
amounts may be made without violation     
	  of the provisions of the Tax Agreement, shall be paid, upon the    
expiration of, or upon the sooner     
	  termination of, the terms of this Indenture, to the Bank to the extent    
money shall be owed to the     
	  Bank under the Reimbursement Agreement (as evidenced by    
written notice thereof given to the     
	  Trustee by the Bank) and, thereafter, to the Company.     
	      
	  	Section 5.08.  Tax Covenants.  (a) The Issuer and the    
Trustee covenant with the Owners of     
	  the Bonds that, notwithstanding any other provision of this    
Indenture or any other instrument, they     
	  will not knowingly make any investment or other use of the    
proceeds of the Bonds or any other     
	  moneys held under this Indenture which would cause the Bonds to    
be "arbitrage bonds" under     
	  section 148 of the Code or "federally guaranteed" obligations    
under section 149(b) of the Code, and     
	  they further covenant that they will comply with all applicable    
requirements of sections 103 and     
	  141-150 of the Code (except that the Issuer and the Trustee shall be    
deemed to have complied with     
	  these requirements as long as they act on the written direction of    
the Company).      
	      
	  	(b)	The Trustee shall maintain the Rebate Fund    
established by Section 5.10 hereof as a     
	  separate fund which shall be continuously held, invested, expended,    
and accounted for in accordance     
	  with the provisions of Section 5.10 hereof; provided, however that    
the Rebate Fund need not be     
	  maintained if the Company, the Issuer, and the Trustee shall have    
received an opinion of Bond     
	  Counsel to the effect that failure to maintain the Rebate Fund shall    
not adversely affect the exclusion     
	  of interest on the Bonds from the federal gross income of the    
Owners thereof.    
	      
	  	(c)	In maintaining the Rebate Fund, the Trustee will    
keep and retain the records described     
	  in Section 5.10 hereof to the extent such records relate to Funds    
held by the Trustee, and the Trustee     
	  will take such further action as the Company may direct pursuant to    
Section 5.10 hereof in order to     
	  comply with the rebate requirements contained in section 148(f) of    
the Code.    
	      
	  	(d)	Notwithstanding any other provision herein to the    
contrary, the Trustee shall be     
	  permitted to transfer moneys on deposit in any of the trust funds    
established hereunder (other than     
	  moneys representing remarketing proceeds or draws under the    
Letter of Credit to the extent needed     
	  to pay principal or purchase price of, premium, if any, or interest    
on the Bonds) to the Rebate Fund.    
	      
	  	Section 5.09.  Custody of Funds and Accounts.  Except as    
otherwise expressly provided herein,     
	  all Funds and Accounts created pursuant to this Indenture and held    
by the Trustee shall be held in     
	  trust, in the name of the Issuer, for the benefit of the Owners and,    
to the extent of amounts owed     
	  by the Company to the Bank under the Reimbursement Agreement,    
the Bank.  Notwithstanding the     
	  foregoing, the Rebate Fund shall be held for the benefit of the    
United States of America.    
	      
	  	Section 5.10.  Rebate Fund, Rebate.  (a)  There is hereby    
created by the Issuer and ordered     
	  established with the Trustee a Rebate Fund.  Moneys held from    
time to time in the Rebate Fund     
	  shall not constitute part of the Trust Estate, but shall be held solely    
for the purpose hereinbelow     
	  described.  Promptly after the end of each fifth Bond Year, the    
Trustee shall determine whether     
	  during the prior five Bond Years any of the funds which it held in    
any of the funds or accounts under     
	  this Indenture (other than the Rebate Fund) were invested in any    
permitted investment.  If the     
	  Trustee determines that any such funds were so invested (except for    
funds so invested in the Bond     
	  Fund which produce gross earnings which amount to less than    
$100,000 during each Bond Year), the     
	  Company shall retain (at its expense) a Rebate Analyst, and the    
following provisions shall apply:     
	  Pursuant to Section 2.2(n) of the Agreement, within thirty (30) days    
after each fifth Bond Year, the     
	  Company shall cause the Rebate Analyst to compute, and deliver to    
the Trustee written notice and     
	  direction of, the amount of any transfer or deposit to the Rebate    
Fund (or, if there has been a loss     
	  in any fund or account other than the Rebate Fund, the amount of    
any withdrawal from the Rebate     
	  Fund) which is necessary to cause the aggregate amount transferred    
to or otherwise deposited in such     
	  Rebate Fund to equal the amount required to be rebated to the    
United States pursuant to the     
	  requirements of section 148 of the Code.  If a deposit to the Rebate    
Fund is required in accordance     
	  with the written direction of the Rebate Analyst, the Trustee shall    
accept such payment from the     
	  Company and deposit it in the Rebate Fund for the benefit of the    
Issuer.  If the computations of the     
	  Rebate Analyst show that a withdrawal may be made from the    
Rebate Fund on account of a loss, the     
	  Trustee shall, upon receipt of an approving opinion of Bond    
Counsel to the effect that such     
	  withdrawal will not adversely affect the exclusion from gross    
income for federal income tax purposes     
	  of interest on the Bonds, and in accordance with the written    
directions of the Company and the     
	  Rebate Analyst, withdraw such amount from the Rebate Fund and    
pay such amount to the Company.      
	  Records of the actions required to be taken by the Trustee by this    
Section 5.10 must be retained by     
	  the Trustee until six (6) years after the last Bond is no longer    
outstanding.    
	      
	  	(b)  Not later than sixty (60) days after the fifth Bond Year    
and every fifth Bond Year     
	  thereafter, the Trustee shall, at the written direction of the Rebate    
Analyst, pay to the United States     
	  Government at least ninety percent (90%) of the amount specified    
in writing by the Rebate Analyst     
	  required to be rebated to the United States from funds on deposit in    
the Rebate Fund or from funds     
	  provided by the Company.  Not later than forty-five (45) days after    
the final retirement of the Bonds,     
	  the Rebate Analyst shall specify in writing to the Trustee the    
amount required to be rebated to the     
	  United States, whereupon the Trustee shall request that the    
Company deposit with the Trustee     
	  pursuant to the Section 2.2(n) of the Agreement such amount, if    
any, as is necessary to bring the     
	  balance in the Rebate Fund to the amount required to be rebated to    
the United States pursuant to     
	  the requirements of section 148 of the Code and, upon receipt of    
such funds from the Company, the     
	  Trustee shall pay to the United States the amount specified in    
writing by the Rebate Analyst to be     
	  paid to the United States; any balance remaining in the Rebate    
Fund after the final payment upon     
	  retirement of the Bonds shall be paid to the Company unless    
otherwise specified in writing by the     
	  Rebate Analyst.  The final payment by the Trustee to the United    
States shall be made no later than     
	  sixty (60) days after the final retirement of the Bonds, to the extent    
funds therefor are on deposit in     
	  the Rebate Fund at such time.    
	      
	  	(c)  The Trustee shall make information regarding the    
Bonds and investments hereunder     
	  available to the Rebate Analyst promptly following each fifth Bond    
Year, shall make deposits to and     
	  disbursements from the Rebate Fund in accordance with the    
directions received from the Rebate     
	  Analyst, shall invest moneys in the Rebate Fund as required by    
Section 5.05 hereof, and shall deposit     
	  income from such investments immediately upon receipt thereof in    
the Rebate Fund.    
	      
	  	(d)  This Section 5.10 is intended to comply with the    
requirements of section 148 of the Code     
	  and the regulations promulgated thereunder.  The requirements of    
this Section 5.10 shall be deemed     
	  modified and amended in the manner and to the extent necessary,    
in the written opinion of Bond     
	  Counsel delivered to the Issuer, the Company, and the Trustee, to    
permit compliance with the     
	  provisions of said section 148 applicable to the Bonds.    
	      
	  	Section 5.11.  Payments in the Project Account;    
Disbursements.  Proceeds of the issuance and     
	  delivery of the Bonds shall be deposited in the Project Account as    
provided in Section 5.01 hereof.      
	  Moneys in the Project Account shall be expended on orders signed    
by an Authorized Company     
	  Representative stating with respect to each payment to be made:    
	      
	      	(a)	The requisition number;    
	       
	      	(b)	The name and address of the person, firm, or    
corporation to whom payment is     
	      due or has been made, which may include the Company;    
	      
	      	(c)	The amount to be or which has been paid;    
	      
	      	(d)	That each obligation mentioned therein has been    
properly incurred, is a proper     
	      charge against the Project Account, and has not been the basis of    
any previous requisition;    
	      
	      	(e)	That each item for which payment is proposed to    
be made is or was necessary     
	      in connection with the Project;    
	      
	      	(f)	That after taking into account the costs proposed to    
be paid or reimbursed in said     
	      certificate, all of the costs paid or reimbursed out of the Project    
Account are amounts which     
	      will be chargeable to the Project's capital account or which would    
be so chargeable either with     
	      a proper election by the Company under the Code or but for a    
proper election by the     
	      Company to deduct such amount and were incurred and paid, or    
are to be incurred and paid,     
	      subsequent to January 17, 1994;    
	      
	      	(g)	That after taking into account the costs proposed to    
be paid or reimbursed in said     
	      certificate, at least 95% of the costs paid or reimbursed out of the    
Bond Proceeds Fund are     
	      for land costs or costs of property of a character subject to the    
allowance for depreciation for     
	      federal income tax purposes and were incurred and paid, or are    
incurred and paid, subsequent     
	      to January 17, 1994;    
	      
	      	(h)	That after taking into account the costs proposed to    
be paid or reimbursed in said     
	      certificate, no more than $160,000 of the costs paid or    
reimbursed out of the Bond Proceeds     
	      Fund are issuance costs within the meaning of the Code; and    
	      
	  		(i)	That no Event of Default exists under the    
Agreement.    
	      
	  	The Trustee is hereby authorized and directed to make each    
disbursement required by the     
	  provisions of the Agreement and to issue its checks therefor.  The    
Trustee shall keep and maintain     
	  adequate records pertaining to the Project Account and all    
disbursements therefrom, and after the     
	  Project has been completed and a certificate of payment of all costs    
is or has been filed as provided     
	  in Section 5.11 hereof, the Trustee shall file an accounting thereof    
with the Issuer, the Guarantor,     
	  and the Company.    
	      
	  	Section 5.12.  Completion of Project.  The completion of the    
Project and payment or provision     
	  made for payment of the full Cost of the Project shall be evidenced    
by the filing with the Trustee of     
	  a certificate required by the provisions of Section 3.3 of the    
Agreement.  Any balance remaining in     
	  the Project Account on the Completion Date shall be used in    
accordance with said Section.    
	      
	  	Section 5.13.  Transfer of Construction Fund.  If the    
Company should prepay all amounts     
	  payable under Section 5.1(a) of the Agreement, any balance then    
remaining in the Project Account     
	  shall without further authorization be deposited in the Bond Fund    
by the Trustee.    
	      
	  	Section 5.14.  Custody of Funds and Accounts.  Except as    
otherwise expressly provided herein,     
	  all Funds and Accounts created pursuant to this Indenture and held    
by the Trustee shall be held in     
	  trust, in the name of the Issuer, for the benefit of the Owners and,    
to the extent of amounts owed     
	  by the Company to the Bank under the Reimbursement Agreement,    
the Bank.     
	      
	  Article VI    
	  Defaults and Remedies    
	      
	  	Section 6.01.  Events of Default.  Each of the following    
shall constitute, and is referred to in     
	  this Indenture as, an "Event of Default":    
	      
	  	(a)	a default in the payment when due of interest on    
any Bond;    
	      
	  	(b)	a default in the payment of principal of, or    
premium, if any, on any Bond when due,     
	  whether at maturity, upon acceleration or redemption, or otherwise;    
	      
	  	(c)	a default in the payment when due of the purchase    
price of any Bond required to be     
	  purchased pursuant to Section 2.03 or Section 2.04;    
	      
	  	(d)	the Issuer fails to perform any of its agreements in    
this Indenture or the Bonds (except     
	  a failure that results in an Event of Default under clause (a), (b), or    
(c) above), the performance of     
	  which is material to the Owners, and which failure continues after    
the giving of the notice of default     
	  and the expiration of the grace period specified in this Section;    
	      
	  	(e)	the Company or the Guarantor fails to perform any    
of its agreements in the Agreement     
	  or the Guaranty (except a failure that results in an Event of Default    
under clause (a), (b), or (c) of     
	  this Section), and the failure continues after the notice and for the    
period specified in this Section;     
	      
	  	(f)	the Company or the Guarantor pursuant to or    
within the meaning of any Bankruptcy     
	  Law (as defined below) (l) commences a voluntary case, (2)    
consents to the entry of an order for     
	  relief against it in an involuntary case, (3) consents to the    
appointment of a Custodian (as defined     
	  below) for the Company or the Guarantor or any substantial part of    
its property, or (4) makes a     
	  general assignment for the benefit of its creditors;    
	      
	  	(g)	a court of competent jurisdiction enters an order or    
decree under any Bankruptcy Law     
	  that (l) is for relief against the Company or the Guarantor in an    
involuntary case, (2) appoints a     
	  Custodian for the Company or the Guarantor or any substantial part    
of its property or (3) orders the     
	  winding up or liquidation of the Company or the Guarantor, and    
the decree or order remains     
	  unstayed and in effect for 60 days;    
	      
	  	(h)	the Trustee receives notice from the Bank that a    
"default" or "event of default" has     
	  occurred and is continuing under the Reimbursement Agreement;    
and    
	      
	  	(i)	the Trustee receives notice from the Bank on or    
before the date or dates specified in     
	  the Letter of Credit following a drawing on the Letter of Credit to    
pay interest on the Bonds that     
	  it will not reinstate its Letter of Credit in the amount of the said    
interest drawing.    
	      
	  	"Bankruptcy Law" means Title 11 of the United States    
Code or any similar Federal or state     
	  law for the relief of debtors.  "Custodian" means any receiver,    
trustee, assignee, liquidator, custodian,     
	  or similar official under any Bankruptcy Law.    
	      
	  	A default under clause (d) or (e) of this Section is not an    
Event of Default until the Trustee     
	  or the Owners of at least a majority in principal amount of the    
Bonds then outstanding give the     
	  Issuer, the Guarantor, and the Company a notice specifying the    
default, demanding that it be     
	  remedied, and stating that the notice is a "Notice of Default,"    
and the Issuer or the Company (if the     
	  default is under clause (d)) or the Company or the Guarantor (if the    
default is under clause (e)) does     
	  not cure the default within 60 days after receipt of the notice, or    
within such longer period as the     
	  Trustee shall agree to.  The Trustee shall not unreasonably refuse to    
agree to a longer cure period     
	  if the default cannot reasonably be cured within 60 days after    
receipt of the notice and the Issuer,     
	  the Guarantor, or the Company has demonstrated to the Trustee    
that it has begun within 60 days and     
	  continued diligent efforts to cure the default and the Trustee has    
received indemnification reasonably     
	  satisfactory to it.  The Issuer authorizes the Company and the    
Guarantor to perform, in the name     
	  and on behalf of the Issuer and for the purpose of preventing the    
occurrence of an Event of Default,     
	  any agreement of the Issuer in this Indenture or the Bonds.    
	      
	  	Section 6.02.  Acceleration.  If an Event of Default under    
clause (h) or (i) of the foregoing     
	  Section occurs, the principal and accrued interest to the date of    
acceleration on the Bonds shall     
	  become due and payable immediately.  If any other Event of Default    
occurs and is continuing, the     
	  Trustee by notice to the Issuer, the Guarantor, and the Company, or    
the Owners of at least a     
	  majority in principal amount of the Bonds then outstanding by    
notice to the Issuer, the Company,     
	  the Guarantor, and the Trustee, may declare the principal of and    
accrued interest on the Bonds to     
	  be due and payable immediately.  Upon the principal of and    
accrued interest on the Bonds becoming     
	  due and payable as provided in this Section, the Trustee shall    
immediately draw on the Letter of     
	  Credit, if any, to pay the principal of and accrued interest on the    
Bonds.  The Trustee shall     
	  immediately give notice of acceleration to the Owners.  Interest on    
the Bonds shall cease to accrue,     
	  and the principal of and accrued and unpaid interest on the Bonds    
shall, without further action,     
	  become immediately due and payable, on the date of acceleration.     
	      
	  	The Trustee may, and upon the request of Owners of a    
majority in principal amount of the     
	  Bonds then outstanding shall, rescind an acceleration and its    
consequences if (a) all existing Events     
	  of Default have been cured or waived, (b) the rescission would not    
conflict with any judgment or     
	  decree, (c) all payments due the Trustee and any predecessor    
Trustee under Section 7.06 have been     
	  made, and (d) when a Letter of Credit is in effect, the Bank    
consents and the Letter of Credit is     
	  reinstated up to the full amount available under it immediately    
prior to such Event of Default.     
	      
	  	Section 6.03.  Other Remedies.  (a)  If an Event of Default    
occurs and is continuing, the     
	  Trustee may pursue any available remedy by proceeding at law or    
in equity to collect the principal     
	  of or interest on the Bonds or to enforce the performance of any    
provision of the Bonds, this     
	  Indenture, the Agreement, the Guaranty, and the Letter of Credit    
including, without limitation, the     
	  exercise of any remedy granted to it in the Agreement.     
	      
	  	(b)	The Trustee may maintain a proceeding even if it    
does not possess any of the Bonds     
	  or does not produce any of them in the proceeding.  A delay or    
omission by the Trustee or any     
	  Owner in exercising any right or remedy accruing upon an Event of    
Default shall not impair the right     
	  or remedy or constitute a waiver of or acquiescence in the Event of    
Default.  No remedy is exclusive     
	  of any other remedy.  All available remedies are cumulative.     
	      
	  	(c)	During any period the Bonds are secured by the    
Letter of Credit and draws thereunder     
	  have been duly honored by the Bank in accordance with the terms    
and provisions of the Letter of     
	  Credit, all remedies pursued by the Trustee upon the occurrence of    
an Event of Default (other than     
	  draws upon the Letter of Credit) shall be taken only with the prior    
consent of the Bank.    
	      
	  	Section 6.04.  Waiver of Past Defaults.  The Owners of a    
majority in principal amount of the     
	  Bonds then outstanding, together with the Bank, by written notice    
to the Trustee, may waive an     
	  existing Event of Default and its consequences if the Letter of    
Credit is reinstated up to the full     
	  amount available under it immediately prior to such Event of    
Default.  When an Event of Default     
	  is waived, it is cured and stops continuing, but no such waiver shall    
extend to any subsequent or other     
	  Event of Default or impair any right consequent to it.     
	      
	  	Section 6.05.  Control by Majority.  The Owners of a    
majority in principal amount of the Bonds     
	  then outstanding may (with the consent of the Bank) direct the    
time, method, and place of     
	  conducting any proceeding for any remedy available to the Trustee    
or of exercising any trust or power     
	  conferred on it.  However, the Trustee may refuse to follow any    
direction that conflicts with law or     
	  this Indenture or, subject to Section 7.01, that the Trustee    
determines is unduly prejudicial to the     
	  rights of other Owners, or would involve the Trustee in personal    
liability.     
	      
	  	Section 6.06.  Limitation on Suits.  An Owner may not    
pursue any remedy with respect to this     
	  Indenture or the Bonds unless (a) the Owner gives the Trustee    
notice stating that an Event of     
	  Default is continuing, (b) the Owners of at least 25% in principal    
amount of the Bonds then     
	  outstanding make a written request to the Trustee to pursue the    
remedy, (c) such Owner or Owners     
	  offer to the Trustee indemnity satisfactory to the Trustee against    
any loss, liability or expense, and     
	  (d) the Trustee does not comply with the request within 60 days    
after receipt of the request and the     
	  offer of indemnity.     
	      
	  	A Owner may not use this Indenture to prejudice the rights    
of another Owner or to obtain a     
	  preference or priority over the other Owners.     
	      
	  	Section 6.07.  Rights of Owners to Receive Payment.     
Notwithstanding any other provision of     
	  this Indenture, the right of any Owner to receive payment of    
principal of and interest on a Bond, on     
	  or after the due dates expressed in the Bond, or the purchase price    
of a Bond on or after the date     
	  for its purchase as provided in the Bond, or to bring suit for the    
enforcement of any such payment     
	  on or after such dates, shall not be impaired or affected without the    
consent of the Owner.     
	      
	  	Section 6.08.  Collection Suit by Trustee.  If an Event of    
Default under Section 6.01(a), (b)     
	  or (c) occurs and is continuing, the Trustee may recover judgment    
in its own name and as trustee of     
	  an express trust against the Company or the Bank for the whole    
amount remaining unpaid.     
	      
	  	Section 6.09.  Trustee May File Proofs of Claim.  The    
Trustee may file such proofs of claim     
	  and other papers or documents as may be necessary or advisable in    
order to have the claims of the     
	  Trustee and the Owners allowed in any judicial proceedings relative    
to the Company or the Bank,     
	  its creditors or its property and, unless prohibited by law or    
applicable regulations, may vote on behalf     
	  of the Owners in any election of a trustee in bankruptcy or other    
person performing similar functions.    
	      
	  	Section 6.10.  Priorities.  If the Trustee collects any money    
pursuant to this Article, it shall pay     
	  out the money in the following order:     
	      
	  	First:  To the Trustee and the Tender Agent for amounts to    
which they are entitled under     
	  Section 7.06 hereof or Section 5.2 of the Agreement, but the    
Trustee may not pay itself or the     
	  Tender Agent from money drawn under the Letter of Credit, from    
the proceeds of the remarketing     
	  of any Bonds, or from amounts held by the Trustee pursuant to    
Article X or Section 5.06(b).    
	      
	  	Second:  To Owners for amounts due and unpaid on the    
Bonds for principal and interest,     
	  ratably, without preference or priority of any kind, according to the    
amounts due and payable on the     
	  Bonds for principal and interest, respectively.       
	  	Third:  To the Bank to the extent the Bank certifies to the    
Trustee that the Company is     
	  indebted to the Bank on account of draws under the Letter of Credit    
or any other amounts due and     
	  payable to the Bank under the Reimbursement Agreement.     
	      
	  	Fourth:  To the Issuer.    
	      
	  	Fifth:  To the Company.     
	      
	  	The Trustee may fix a payment date for any payment to the    
Owners in accordance with this     
	  Section.     
	      
	  	Section 6.11.  Bank Deemed Owner of Certain Bonds.     
Notwithstanding any other provision     
	  in this Article, as long as the Letter of Credit is in effect the Bank    
shall be deemed to be the owner     
	  of all Bonds which are secured by the Letter of Credit and all    
Company Bonds and all Pledged Bonds     
	  for all purposes of this Article VI following the occurrence of an    
Event of Default.  In no event,     
	  however, may the Bank direct the Trustee not to draw on the Letter    
of Credit, or prevent the     
	  Trustee from so drawing, pursuant to the provisions of this Article    
VI after the occurrence of an     
	  Event of Default under clause (h) or (i) of Section 6.01 hereof.    
	      
	  	Section 6.12.  Bank Rights.  Notwithstanding any other    
provision of this Article, as long as the     
	  Letter of Credit is in effect or amounts are owed to the Bank under    
the Reimbursement Agreement,     
	  the Trustee shall take any action that it is required or permitted to    
take under this Article VI (except     
	  for the Trustee's obligations to draw under a Letter of Credit due to    
an Event of Default under     
	  clause (h) or (i) of Section 6.01, which shall be absolute and    
unconditional) solely at the written     
	  direction of the Bank, and the Trustee shall not take any such    
action without such written direction.    
	      
	      
	  Article VII    
	  Trustee, Remarketing Agent, and Tender Agent    
	      
	  	Section 7.01.  Duties of Trustee.  (a)  Prior to the occurrence    
of an Event of Default, the     
	  Trustee shall have no liability for any action or omission in the    
performance of its duties hereunder,     
	  except in the case of negligence or willful misconduct on the part of    
the Trustee.  During the     
	  existence of an Event of Default, the Trustee shall exercise its    
rights and powers and use the same     
	  degree of care and skill in their exercise as a prudent person would    
exercise or use under the     
	  circumstances in the conduct of such person"s own affairs.     
	      
	  	(b)	Except during the continuance of an Event of    
Default,     
	      
	      	(i)	the Trustee shall be required to perform only those    
duties that are specifically     
	      set forth in this Indenture and no others, and     
	      
	      	(ii)	in the absence of bad faith on its part, the Trustee    
may conclusively rely, as to     
	      the truth of the statements and the correctness of the opinions    
expressed, upon certificates or     
	      opinions furnished to the Trustee and conforming to the    
requirements of this Indenture.      
	      However, the Trustee shall examine the certificates and opinions    
to determine whether they     
	      conform to the requirements of this Indenture.     
	      
	  	(c)	The Trustee may not be relieved from liability for    
its own negligent action, its own     
	  negligent failure to act or its own willful misconduct, except that      
	      	(i)	this paragraph does not limit the effect of    
paragraph (b) of this Section,     
	      
	      	(ii)	the Trustee shall not be liable for any error of    
judgment made in good faith by     
	      any employee of the Trustee assigned by the Trustee to    
administer its corporate trust matters     
	      (a "Responsible Officer"), unless it is proved that the Trustee    
was negligent in ascertaining the     
	      pertinent facts;     
	      
	      	(iii)	the Trustee shall not be liable with respect to any    
action it takes or omits to take     
	      in good faith in accordance with a direction received by it    
pursuant to Section 6.05; and     
	      
	      	(iv)	no provision of this Indenture shall require the    
Trustee to expend or risk its own     
	      funds or otherwise incur any financial liability in the    
performance of any of its duties hereunder     
	      or in the exercise of any of its rights or powers, if it shall have    
reasonable grounds for believing     
	      that repayment of such funds or adequate indemnity against such    
risk or liability is not     
	      reasonably assured to it.     
	      
	  	(d)	Every provision of this Indenture that in any way    
relates to the Trustee is subject to all     
	  the paragraphs of this Section.     
	      
	  	(e)	The Trustee may refuse to perform any duty or    
exercise any right or power unless it     
	  receives indemnity satisfactory to it against any loss, liability, or    
expense, but the Trustee may not     
	  require indemnity as a condition to declaring the principal of,    
premium, if any, and interest on the     
	  Bonds to be due immediately under Section 6.02 or to drawing on    
the Letter of Credit or to making     
	  any payment of principal or interest on the Bonds.    
	      
	  	(f)	The Trustee shall not be liable for interest on any    
cash held by it.      
	      
	  	Section 7.02.  Rights of Trustee.  Subject to the foregoing    
Section:    
	      
	  	(a)	The Trustee may rely on any document reasonably    
believed by it to be genuine and to     
	  have been signed or presented by the proper person.  The Trustee    
need not investigate any fact or     
	  matter stated in the document.      
	      
	  	(b)	Before the Trustee acts or refrains from acting, it    
may require a certificate of an     
	  appropriate officer or officers of the Issuer or the Company or an    
opinion of counsel; provided that     
	  it may not require such a certificate as a condition to declaring the    
principal of and interest on the     
	  Bonds to be due immediately under Section 6.02 or to drawing on    
the Letter of Credit or to making     
	  any payment on the Bonds.  The Trustee shall not be liable for any    
action it takes or omits to take     
	  in good faith in reliance on the certificate or opinion of counsel.      
	      
	  	(c)	The Trustee may act through agents or co-trustees    
and shall not be responsible for the     
	  misconduct or negligence of any agent or co-trustee appointed with    
due care.      
	      
	  	Section 7.03.  Individual Rights of Trustee.  The Trustee in    
its individual or any other capacity     
	  may become the Owner or pledgee of Bonds and may otherwise    
deal with the Issuer or with the     
	  Company or its affiliates with the same rights it would have if it    
were not trustee.  Any paying agent     
	  may do the same with like rights.      
	      
	  	Section 7.04.  Trustee"s Disclaimer.  The Trustee makes    
no representation as to the validity     
	  or adequacy of this Indenture or the Bonds, it shall not be    
accountable for the Company"s use of     
	  the proceeds from the Bonds paid to the Company, and it shall not    
be responsible for any statement     
	  in the Bonds other than its certificate of authentication.      
	      
	  	Section 7.05.  Notice of Defaults.  (a) If an event occurs    
which with the giving of notice or     
	  lapse of time or both would be an Event of Default, and if the event    
is continuing and if it is known     
	  to the Trustee, the Trustee shall mail to each Owner and the Bank    
notice of the event within 30 days     
	  after it occurs.  Except in the case of a default in payment or    
purchase on any Bonds, the Trustee     
	  may withhold the notice if and so long as a committee of its    
Responsible Officers (as defined in     
	  Section 7.01(c)) in good faith determines that withholding the    
notice is in the interests of Owners.      
	      
	  	(b)	The Trustee shall not be required to take notice or    
be deemed to have notice of any     
	  default or Event of Default hereunder, or in any other document or    
instrument executed in     
	  connection with the execution and delivery of the Bonds, except an    
Event of Default under Section     
	  6.01(a), (b), (c), (h) or (i) hereof, unless the Trustee shall be    
specifically notified in writing of such     
	  default or Event of Default by the Issuer, the Tender Agent, the    
Bank, the Company, or the Owners     
	  of at least 25% in aggregate principal amount of the Bonds then    
Outstanding.  All notices or other     
	  instruments required by this Indenture to be delivered to a    
responsible officer of the Trustee shall     
	  be delivered at the corporate trust office of the Trustee and, in the    
absence of such notice so     
	  delivered, the Trustee may conclusively assume there is no default    
except as aforesaid.    
	      
	  	Section 7.06.  Compensation and Indemnity of Trustee.  For    
acting under this Indenture, the     
	  Trustee shall be entitled to payment of compensation as outlined in    
its fee schedule for its services     
	  and reimbursement of advances, counsel fees, and other expenses    
reasonably and necessarily made     
	  or incurred by the Trustee in connection with its services under this    
Indenture.      
	      
	  	To secure the payment or reimbursement to the Trustee    
provided for in this Section, the     
	  Trustee shall have a senior claim, to which the Bonds are made    
subordinate, on all money or property     
	  held or collected by the Trustee, except that held under Article X or    
otherwise held in trust to pay     
	  principal of and interest on particular Bonds and except amounts    
drawn under the Letter of Credit     
	  or remarketing proceeds held by the Trustee or Tender Agent    
hereunder.    
	      
	  	The Company has agreed in the Agreement to indemnify    
the Trustee for, and to hold it     
	  harmless against, certain losses, liabilities, and expenses incurred    
by the Trustee.      
	      
	  	Section 7.07.  Eligibility of Trustee.  The Trustee shall be a    
corporation organized and doing     
	  business under the laws of the United States or any state or the    
District of Columbia, authorized     
	  under such laws to exercise corporate trust powers in the State, and    
subject to supervision or     
	  examination by United States, state or District of Columbia

Trustee must be an institution     
	  acceptable to the Issuer, authorized to act as a trustee in the State,    
and rated at least "Baa3" by     
	  Moody"s Investors Service (or Moody"s Investors Service shall

	  such successor Trustee is otherwise acceptable to Moody"s    
Investors Service) if the Bonds are then     
	  rated by Moody"s Investors Service, and at least "BBB-" or    
"A-3" by Standard & Poor"s     
	  Corporation (or Standard & Poor"s Corporation shall have

Corporation) if the Bonds are then     
	  rated by Standard & Poor"s Corporation, and authorized by law to    
perform all the duties imposed     
	  upon it as Trustee by this Indenture.    
	      
	  	Section 7.08.  Replacement of Trustee.  The Trustee may    
resign by notifying the Issuer and     
	  the Company.  The Owners of a majority in principal amount of the    
Bonds then outstanding may     
	  remove the Trustee by notifying the removed Trustee and may    
appoint a successor Trustee with the     
	  Issuer"s, the Bank"s, and the Company"s prior written consent.     
If no Event of Default shall have     
	  occurred and be continuing, the Company may cause the Trustee to    
be removed, with the consent     
	  of the Remarketing Agent and the Issuer, by giving notice to the    
Issuer and the Bank requesting the     
	  Issuer to remove and replace the Trustee.  In addition, the Issuer    
shall, at the direction of the     
	  Company or on its own volition, remove the Trustee if (a) the    
Trustee fails to comply with     
	  Section 7.07 hereof, (b) the Trustee is adjudged a bankrupt or an    
insolvent, (c) a receiver or other     
	  public officer takes charge of the Trustee or its property or (d) the    
Trustee otherwise becomes     
	  incapable of acting.      
	      
	  	If the Trustee resigns or is removed from the office of    
Trustee for any reason, the Issuer, with     
	  the prior written consent of the Bank and the Company, shall    
promptly appoint a successor Trustee.      
	      
	  	A successor Trustee shall deliver a written acceptance of its    
appointment to the retiring     
	  Trustee and to the Issuer.  Immediately thereafter, the retiring    
Trustee shall transfer all property     
	  (including the Letter of Credit) held by it as Trustee to the    
successor Trustee, the resignation or     
	  removal of the retiring Trustee shall then (but only then) become    
effective, and the successor Trustee     
	  shall have all the rights, powers, and duties of the Trustee under    
this Indenture.      
	      
	  	If a successor Trustee does not take office within 60 days    
after the retiring Trustee resigns or     
	  is removed, the retiring Trustee, the Issuer, the Company, the    
Bank, the Guarantor, or the Owners     
	  of a majority in principal amount of the Bonds then outstanding    
may petition any court of competent     
	  jurisdiction for the appointment of a successor Trustee.      
	      
	  	If the Trustee fails to comply with the foregoing Section,    
any Owner may petition any court     
	  of competent jurisdiction for the removal of the Trustee and the    
appointment of a successor Trustee.    
	      
	  	Section 7.09.  Duties of Remarketing Agent.  The    
Remarketing Agent will determine the     
	  interest rate on the Bonds as provided in this Indenture as the    
designee of the Issuer.  The     
	  Remarketing Agent will remarket Bonds as provided in this    
Indenture as the designee of the     
	  Company.  The Remarketing Agent may for its own account or as    
broker or agent for others deal     
	  in Bonds and may do anything any other Owner may do to the    
same extent as if the Remarketing     
	  Agent were not serving as such.      
	      
	  	Section 7.10.  Eligibility of Remarketing Agent;    
Replacement.  The initial Remarketing Agent     
	  shall be The First National Bank of Chicago, Chicago Illinois.  Any    
successor Remarketing Agent     
	  must be an institution acceptable to the Issuer and rated at least    
"Baa3" by Moody"s Investors     
	  Service (or Moody"s Investors Service shall have provided written

	  Remarketing Agent is otherwise acceptable to Moody"s Investors    
Service) if the Bonds are then     
	  rated by Moody"s Investors Service, and at least "BBB-" or    
"A-3" by Standard & Poor"s     
	  Corporation (or Standard & Poor"s Corporation shall have

	  successor Remarketing Agent is otherwise acceptable to Standard &    
Poor"s Corporation) if the     
	  Bonds are then rated by Standard & Poor"s Corporation, and    
authorized by law to perform all the     
	  duties imposed upon it by this Indenture.      
	      
	  	A Remarketing Agent may at any time resign from its    
duties under this Indenture by giving at     
	  least 30 days" written notice to the Issuer, the Company, the    
Guarantor, the Bank, the Tender     
	  Agent, and the Trustee.  The Trustee shall mail a copy of such    
notice by certified mail to each of the     
	  Bond Owners.  A Remarketing Agent may be removed at any time    
at the direction of the Issuer and     
	  the Company by an instrument signed by the Issuer and the    
Company and filed at least 30 days prior     
	  to such removal with the Remarketing Agent, the Bank, and the    
Trustee.  No removal or resignation     
	  hereunder shall become effective prior to the acceptance of    
appointment of a successor Remarketing     
	  Agent hereunder.      
	      
	  	While the Bonds are in a Book-Entry System, the    
Remarketing Agent shall serve as the     
	  Participant on behalf of all of the Beneficial Owners of the Bonds.    
	      
	  	Section 7.11.  Tender Agent.  (a)  During any period the    
Bonds shall not be in a Book-Entry     
	  System, the Company shall appoint a Tender Agent for the Bonds,    
who shall be satisfactory to the     
	  Issuer, the Trustee, and the Remarketing Agent and who, upon    
acceptance of its duties, will perform     
	  the obligations of the Tender Agent set forth in this Indenture.  Any    
Tender Agent must be an     
	  institution rated at least "Baa3" by Moody"s Investors Service    
(or Moody"s Investors Service shall     
	  have provided written evidence that such successor Tender Agent is    
otherwise acceptable to Moody"s     
	  Investors Service) if the Bonds are then rated by Moody"s    
Investors Service, and at least "BBB-" or     
	  "A-3" by Standard & Poor"s Corporation (or Standard &    
Poor"s Corporation shall have provided     
	  written evidence that such successor Tender Agent is otherwise    
acceptable to Standard & Poor"s     
	  Corporation) if the Bonds are then rated by Standard & Poor"s    
Corporation, and authorized by law     
	  to perform all the duties imposed upon it as Tender Agent by this    
Indenture.  The initial Tender     
	  Agent and any successor Tender Agent shall accept its duties    
hereunder by a written certificate or     
	  tender agent agreement delivered to the Trustee, which certificate    
or agreement shall designate the     
	  Principal Office of the Tender Agent.      
	      
	  	(b)	The Tender Agent may at any time resign by    
giving thirty (30) days" notice to the     
	  Issuer, the Trustee, the Company, the Bank, and the Remarketing    
Agent.  Promptly upon the receipt     
	  of such notice, the Trustee shall mail copies thereof to each    
registered Owner of the Bonds.  In no     
	  event, however, shall any resignation of the Tender Agent take    
effect until a successor Tender Agent     
	  shall have been appointed.    
	      
	  	(c)	The Tender Agent may be removed at any time by    
an instrument in writing delivered     
	  to the Trustee and the Tender Agent by the Company, with the    
prior written approval of the Bank     
	  and the Issuer.  In no event, however, shall any removal of the    
Tender Agent take effect until a     
	  successor Tender Agent shall have been appointed.      
	      
	  	(d)	Written notice of the appointment of a Tender    
Agent shall immediately be given by the     
	  Trustee to the Issuer and to the Owners.  If no successor to a    
Tender Agent has accepted     
	  appointment in the manner provided above within 30 days after the    
Tender Agent has given notice     
	  of its resignation as provided above, the Trustee shall serve as    
Tender Agent or shall appoint an     
	  agent to act in its stead.      
	      
	  	Section 7.12.  Successor Trustee, Remarketing Agent, or    
Tender Agent by Merger.  If the     
	  Trustee, the Tender Agent, or the Remarketing Agent consolidates    
with, merges, or converts into,     
	  or transfers all or substantially all its assets (or, in the case of a    
bank or trust corporation, its     
	  corporate trust assets) to, another corporation, the resulting,    
surviving, or transferee corporation     
	  without any further act shall, if otherwise eligible to serve    
hereunder, be the successor Trustee,     
	  Tender Agent, or Remarketing Agent.      
	      
	      
	      
   
   
	  Article VIII    
	  Supplemental Indentures

	  	(a)	to cure any ambiguity, inconsistency, or formal    
defect or omission;     
	      
	  	(b)	to grant to the Trustee for the benefit of the    
Owners additional rights, remedies,     
	  powers, or authority;

	  	(d)	to modify this Indenture or the Bonds to permit    
qualification under the Trust Indenture

permit the qualification of the     
	  Bonds for sale under the securities laws of any state of the United    
States;     
	      
	  	(e)	to evidence the succession of a new Trustee or the    
appointment by the Trustee or the     
	  Issuer of a co-trustee;     
	      
	  	(f)	to make any change that does not materially    
adversely affect the rights of any Owner;     
	      
	  	(g)	to facilitate the use of the Book-Entry System; and    
	      
	  	(h)	to facilitate the substitution of an Alternate Credit    
Facility which is not an irrevocable     
	  letter of credit, but without modifying the payment terms of the    
Bonds.    
	      
	  	Section 8.02.  With Consent of Owners.  If an amendment    
of or supplement to this Indenture     
	  or the Bonds without any consent of Owners is not permitted by the    
preceding Section, the Issuer     
	  and the Trustee may enter into such amendment or supplement    
with the consent of the Owners of     
	  at least a majority in principal amount of the Bonds then    
Outstanding.  However, without the consent     
	  of each Owner affected, no amendment or supplement may (a)    
extend the maturity of the principal     
	  of, or the due date of the payment of interest on, any Bond, (b)    
reduce the principal amount of, or     
	  rate of interest on, any Bond, (c) effect a privilege or priority of any    
Bond or Bonds over any other     
	  Bond or Bonds, (d) reduce the percentage of the principal amount    
the Bonds required for consent     
	  to such amendment or supplement, (e) impair the excludability    
from gross income for federal income     
	  tax purposes of interest on any Bond, (f) eliminate the Owners"    
rights to demand that their Bonds     
	  be purchased, or any mandatory tender or redemption of the Bonds,    
(g) extend the due date for the     
	  purchase of Bonds put by the Owners thereof or call for mandatory    
tender or redemption or reduce     
	  the purchase or redemption price of such Bonds, (h) create a lien    
ranking prior to or on a parity with     
	  the lien of this Indenture on the property described in the Granting    
Clause of this Indenture not     
	  otherwise provided for herein, or (i) deprive any Owner of the lien    
created by this Indenture on such     
	  property.  In addition, if moneys or Governmental Obligations have    
been deposited or set aside with     
	  the Trustee pursuant to Article X for the payment of the Bonds and    
the Bonds shall not have in fact     
	  been actually paid in full, no amendment to the provisions of that    
Article shall be made without the     
	  consent of the Owners of each of those Bonds affected.    
	      
	  	Section 8.03.  Effect of Consents.  After an amendment or    
supplement becomes effective, it     
	  will bind every Owner unless it makes a change described in any of    
the lettered clauses of the     
	  preceding Section.  In that case, the amendment or supplement will    
bind each Owner who consented     
	  to it and each subsequent Owner of a Bond or portion of a Bond    
evidencing the same debt as the     
	  consenting Owner"s Bond.      
	      
	  	Section 8.04.  Notation on or Exchange of Bonds.  If an    
amendment or supplement changes     
	  the terms of a Bond, the Trustee may require the Owner to deliver    
it to the Trustee.  The Trustee     
	  may place an appropriate notation on the Bond about the changed    
terms and return it to the Owner.      
	  Alternatively, if the Trustee, the Issuer, and the Company    
determine, the Issuer in exchange for the     
	  Bond will issue and the Trustee will authenticate a new Bond that    
reflects the changed terms.      
	      
	  	Section 8.05.  Execution and Delivery by Trustee of    
Amendments and Supplements.  The     
	  Trustee shall execute and deliver any amendment or supplement to    
the Indenture or the Bonds     
	  authorized by this Article if the amendment or supplement does not    
adversely affect the rights, duties,     
	  liabilities, or immunities of the Trustee.  In signing such    
amendment or supplement, the Trustee will     
	  be entitled to receive and (subject to Section 7.01) will be fully    
protected in relying on an opinion     
	  of Bond Counsel stating that such amendment or supplement is    
authorized by this Indenture.      
	      
	  	Section 8.06.  Company and Bank Consent Required.  An    
amendment or supplement to this     
	  Indenture or the Bonds shall not become effective unless the    
Company and the Bank shall deliver     
	  to the Trustee their written consents to the amendment or    
supplement.  The Company shall be     
	  deemed to have consented if it shall fail to deliver a written    
objection to the Trustee within 30 days     
	  after receipt by the Company of a proposed form of an amendment    
or supplement.      
	      
	  	Section 8.07.  Notice to Owners.  The Trustee shall cause    
notice of the execution of each     
	  supplement or amendment to this Indenture or the Agreement to be    
mailed to the Owners.  The     
	  notice shall, at the option of the Trustee, either (a) briefly state the    
nature of the amendment or     
	  supplement and that copies of it are on file with the Trustee for    
inspection by Owners or (b) enclose     
	  a copy of such amendment or supplement.      
	      
	  Article IX    
	  Amendment of Agreement, Guaranty, or Letter of Credit    
	      
	  	Section 9.01.  Without Consent of Owners.  The Issuer may    
enter into, and the Trustee may     
	  consent to, any amendment of or supplement to the Agreement and    
the Trustee may enter into any     
	  amendment of or supplement to the Guaranty, without notice to or    
consent of any Owner, if the     
	  amendment or supplement is (a) required or permitted by the    
provisions of the Agreement, the     
	  Guaranty, or this Indenture, (b) to cure any ambiguity,    
inconsistency, or formal defect or omission,     
	  (c) in connection with any authorized amendment of or supplement    
to this Indenture, (d) to make     
	  any change that does not materially adversely affect the rights of    
any Owner, (e) to amend the     
	  description of the Project, provided the Trustee is provided an    
opinion of Bond Counsel to the effect     
	  that such amendment will not adversely affect the excludability    
from gross income of interest on the     
	  Bonds for federal income tax purposes, or (f) to facilitate the    
substitution of an Alternate Credit     
	  Facility which is not an irrevocable letter of credit, but without    
modifying the payment terms of the     
	  Bonds.    
	      
	  	Section 9.02.  With Consent of Owners.  If an amendment    
of or supplement to the Agreement     
	  or the Guaranty without any consent of Owners is not permitted by    
the foregoing Section, the Issuer     
	  may enter into, and the Trustee may consent to, such amendment or    
supplement (or in the case of     
	  the Guaranty, the Trustee may enter into such amendment or    
supplement) with the consent of the     
	  Owners of at least a majority in principal amount of the Bonds then    
outstanding.  However, without     
	  the consent of each Owner affected, no amendment or supplement    
may result in anything described     
	  in the lettered clauses of Section 8.02.      
	      
	  	Section 9.03.  Bank Consent Required.  An amendment or    
supplement to the Agreement or     
	  the Guaranty authorized by this Article shall not become effective    
unless the Bank delivers to the     
	  Trustee its written consent to the amendment or supplement.      
	      
	  	Section 9.04.  Modifications of Letter of Credit.  No Letter    
of Credit may be modified without     
	  the prior written consent of 100% of the Owners of the Bonds,    
except to (a) correct any formal     
	  defects therein, (b) effect transfers thereof, (c) effect extensions    
thereof, (d) effect reductions and     
	  reinstatements thereof in accordance with the terms of the Letter of    
Credit, (e) increase the stated     
	  amount thereof, (f) effect any change which does not have a    
material adverse effect upon the     
	  interests of the Owners, or (g) any amendment effective from and    
after a mandatory tender date     
	  hereunder.  Pursuant to this Indenture however, the Company has    
the right to obtain an Alternate     
	  Credit Facility, subject to the requirements set forth therein without    
the consent of the Owners.      
	      
	  	Section 9.05.  Release of Guaranty.  In connection with an    
assignment described in Section 8.1     
	  of the Agreement, the Trustee shall release the Guarantor from its    
obligations under the Guaranty     
	  if so directed in writing by the Company and the Guarantor.  In    
such event, the Bonds shall be     
	  subject to mandatory tender pursuant to Section 2.04(e) hereof and    
the Trustee shall give the notice     
	  to Owners described in said Section 2.04.  No consent of the    
Owners or the Bank and no notice to     
	  the Owners or the Bank other than that referenced above shall be    
required to be obtained or given     
	  in connection with such release.  Notwithstanding the foregoing, no    
such release shall then be     
	  permitted if (a) the Bonds are then in the CP Rate Mode, or (b) if    
the Bonds are then in an     
	  Adjustable Rate Period of greater than one year's duration, unless    
the release occurs on a date on     
	  which the Bonds may be optionally redeemed pursuant to the    
Indenture and the mandatory tender     
	  price payable upon the mandatory tender of Bonds as a result of    
such release includes a premium     
	  equal to the redemption premium at that time payable pursuant to    
the optional redemption provisions     
	  of the Indenture.    
	      
	      
	  Article X    
	  Discharge of Indenture    
	      
	  	Section 10.01.  Bonds Deemed Paid; Discharge of    
Indenture.  Any Bond will be deemed paid     
	  for all purposes of this Indenture when (a) payment of the principal    
of and interest on the Bond to     
	  the due date of such principal and interest (whether at maturity,    
upon redemption or otherwise)     
	  either (i) has been made in accordance with the terms of the Bond    
or (ii) has been provided for by     
	  depositing with the Trustee Available Moneys sufficient to make    
such payment and/or Government     
	  Obligations (purchased with Available Moneys) maturing as to    
principal and interest in such amounts     
	  and at such times as will, in the opinion of an independent certified    
pubic accountant delivered to     
	  the Trustee, ensure the availability of sufficient moneys to make    
such payment, and (b) all     
	  compensation and expenses of the Trustee pertaining to each Bond    
in respect of which such deposit     
	  is made have been paid or provided for to the Trustee"s    
satisfaction.  When a Bond is deemed paid,     
	  it will no longer be secured by or entitled to the benefits of this    
Indenture or be an obligation of the     
	  Issuer, except for payment from moneys or Government    
Obligations under clause (a)(ii) above.    
	      
	  	Notwithstanding the foregoing, no deposit under clause    
(a)(ii) of the first paragraph of this     
	  Section shall be deemed a payment of a Bond until the Company or    
the Guarantor has furnished the     
	  Trustee an opinion of Bond Counsel stating that the deposit of such    
cash or Government Obligations     
	  will not cause the Bonds, or any portion thereof, to become    
"arbitrage bonds" within the meaning     
	  of section 148 of the Code and (A) notice of redemption of the    
Bond is given in accordance with this     
	  Indenture or, if the Bond is not to be redeemed or paid within the    
next 60 days, until the Company     
	  has given the Trustee, in form satisfactory to the Trustee,    
irrevocable instructions (1) to notify, as     
	  soon as practicable, the Owner of the Bond, in accordance with this    
Indenture, that the deposit     
	  required by clause (a)(ii) above has been made with the Trustee and    
that the Bond is deemed to be     
	  paid under this Article and stating the maturity or redemption date    
upon which moneys are to be     
	  available for the payment of the principal of the Bond, and, if the    
Bond is to be redeemed rather     
	  than paid at maturity, (2) to give notice of redemption as provided    
herein for such Bond, or (B) the     
	  maturity of the Bond.  In addition, notwithstanding the foregoing,    
if the Bonds are then in the Daily     
	  Rate Mode or the Weekly Rate Mode, no deposit under clause    
(a)(ii) of the first paragraph of this     
	  Section shall be deemed a payment of a Bond unless the Trustee    
receives written evidence from the     
	  Rating Agency that such deposit would not result in a reduction or    
withdrawal of the ratings then     
	  maintained on the Bonds.    
	      
	  	When all outstanding Bonds are deemed paid under the    
foregoing provision of this Section,     
	  the Letter of Credit has been surrendered to the Bank for    
cancellation, and all amounts due and     
	  payable to the Bank under the Reimbursement Agreement have    
been paid in full, the Trustee will     
	  upon request acknowledge the discharge of the lien of this    
Indenture as to the Bonds, provided,     
	  however that the obligations under Article II in respect of the    
optional tender rights of the Owners     
	  of the Bonds and the transfer, exchange, registration, discharge    
from registration, and replacement     
	  of Bonds shall survive the discharge of the lien of the Indenture.      
	      
	  	The Trustee shall provide each Rating Agency then rating    
the Bonds with at least 10 days prior     
	  notice of any advance defeasance of the Bonds, together with a copy    
of the opinion of independent     
	  certified public accountant described in the first paragraph of this    
Section and any opinion of counsel     
	  delivered if Available Moneys described in clause (c) of the    
definition thereof are used to effect the     
	  defeasance.  The Trustee shall notify each Owner of the advance    
defeasance of the Bonds, within 10     
	  days after such defeasance.      
	      
	  	Section 10.02.  Application of Trust Money.  The Trustee    
shall hold in trust moneys or     
	  Governmental Obligations deposited with it pursuant to the    
preceding Section and shall apply the     
	  deposited money and the money from the Governmental    
Obligations in accordance with this     
	  Indenture only to the payment of principal of and interest on the    
Bonds and to the payment of the     
	  purchase price of Bonds demanded to be purchased by Owners.      
	      
	  	Section 10.03.  Repayment to Bank and Company.  At such    
time as no Bonds remain unpaid     
	  within the meaning of Section 10.01, the Trustee shall promptly    
pay first to the Bank (to the extent     
	  the Bank certifies to the Trustee that the Company is indebted to it    
for amounts owed under the     
	  Reimbursement Agreement) and then to the Company upon request    
(i) any excess money or     
	  securities held by the Trustee at any time under this Article and (ii)    
any money held by the Trustee     
	  under any provision of this Indenture for the payment of principal    
or interest or for the purchase of     
	  Bonds that remains unclaimed for two years.    
	      
	      
	  Article XI    
	  Miscellaneous    
	      
	  	Section 11.01.  Owners" Consent.  Any consent or other    
instrument required by this Indenture     
	  to be signed by Owners may be in any number of counterpart    
documents and may be signed by a     
	  Owner or by the Owner"s agent appointed in writing.  Proof of the    
execution of such instrument or     
	  of the instrument appointing an agent and of the Ownership of    
Bonds, if made in the following     
	  manner, shall be conclusive for any purposes of this Indenture with    
regard to any action taken by the     
	  Trustee or the Tender Agent under the instrument:     
	      
	  	(a)	The fact and date of a person"s signing an    
instrument may be proved by the certificate     
	  of any officer in any jurisdiction who by law has power to take    
acknowledgments within that     
	  jurisdiction that the person signing the writing acknowledged    
before the officer the execution of the     
	  writing, or by an affidavit of any witness to the signing.      
	      
	  	(b)	The fact of Ownership of Bonds, the amount or    
amounts, numbers and other     
	  identification of such Bonds and the date of holding shall be proved    
by the registration books kept     
	  pursuant to this Indenture.      
	      
	  	In determining whether the Owners of the required    
principal amount of Bonds outstanding     
	  have taken any action under this Indenture (and solely for such    
purposes), Bonds owned by the     
	  Company or any person controlling, controlled by, or under    
common control with the Company shall     
	  be disregarded and deemed not to be outstanding, unless the    
Company shall be the Owner of 100%     
	  of the Bonds.  In determining whether the Trustee and the Tender    
Agent shall be protected in     
	  relying on any such action, only Bonds which the Trustee knows to    
be so owned shall be disregarded.      
	      
	  	Any consent or other instrument shall be irrevocable and    
shall bind any subsequent Owner of     
	  such Bond or any Bond delivered in substitution therefor.      
	      
	  	Section 11.02.  Limitation of Rights.  Nothing expressed or    
implied in this Indenture or the     
	  Bonds shall give any person other than the Trustee, the Tender    
Agent, the Issuer, the Bank, the     
	  Company, the Guarantor, the Remarketing Agent, and the Owners    
any right, remedy, or claim under     
	  or with respect to this Indenture.      
	      
	  	Section 11.03.  No Personal Liability of Issuer.  No    
covenant, agreement, or obligation     
	  contained herein or in the Bonds shall be deemed to be a covenant,    
agreement, or obligation of any     
	  present or future officer, of the employee or agent of the Issuer in    
such person"s individual capacity,     
	  and neither the officials or officers of the Issuer executing this    
Indenture or the Bonds shall be liable     
	  personally on the Bonds or under this Indenture or be subject to any    
personal liability of     
	  accountability by reason of the issuance, execution or delivery of    
the Bonds.  No officer, employee,     
	  or agent of the Issuer shall incur any personal liability with respect    
to any other action taken, or not     
	  taken, by such person pursuant to this Indenture, the Agreement, or    
the Act provided such person     
	  does not act with malicious intent.    
	      
	  	Section 11.04.  Severability.  If any provisions of this    
Indenture shall be held or deemed to be     
	  or shall, in fact, be invalid, inoperative, or unenforceable, the same    
shall not affect any other

	  	This Bond is authorized and issued under and pursuant to    
authority conferred by the Act,     
	  certain proceedings of the Board of Directors of the Issuer and the    
Indenture of Trust dated as of     
	  April 1, 1994 (the "Indenture") between the Issuer and the    
Trustee.  Certain terms used and not     
	  defined in this Bond are defined in the Indenture.  This Bond is one    
of the Issuer"s duly authorized     
	  Industrial Development Revenue Bonds, Series 1994 (Trencor    
Jetco, Inc. Project) (the "Bonds"),     
	  which Bonds have been issued in the aggregate principal amount of    
$8,000,000 to provide funds to     
	  make a loan to Trencor Jetco, Inc., a Texas corporation (the    
"Company") pursuant to a Loan     
	  Agreement dated as of April 1, 1994 (the "Agreement") between    
the Issuer and the Company.  The     
	  proceeds of the Bonds will be used to finance a portion of the costs    
of acquisition, construction and     
	  equipping of certain facilities (the "Project") located in the Unit.     
As security for the payment of the     
	  Bonds, the Company has caused to be delivered to the Trustee a    
letter of credit (the "Initial Letter     
	  of Credit") of The First National Bank of Chicago (the "Bank"),    
against which the Trustee shall be     
	  entitled to draw, in accordance with the terms thereof, to pay when    
and as due, the principal or     
	  purchase price of, and interest on, the Bonds during the term of the    
Initial Letter of Credit.  Under     
	  certain conditions, the Company may cause to be delivered an    
Alternate Credit Facility (an     
	  "Alternate Credit Facility") in substitution for the Letter of    
Credit then in effect without the consent     
	  of the Owners of the Bonds.  The Initial Letter of Credit, together    
with any Alternate Credit Facility,     
	  is hereinafter referred to as the "Letter of Credit".  The Bonds are    
guaranteed by Astec Industries,     
	  Inc., a Tennessee corporation (the "Guarantor"), the owner of 100%    
of the outstanding stock of the     
	  Company, pursuant to a Guaranty Agreement dated April 1, 1994,    
between the Guarantor and the     
	  Trustee.  The Bonds are not secured by any lien on or security    
interest in the Project.    
	      
	  	The Bonds are issued under and entitled to the benefits of    
the Indenture.  Pursuant to the     
	  Indenture, the Issuer has pledged and assigned to the Trustee the    
Trust Estate as security for its     
	  obligation to pay the principal or purchase price of, premium, if    
any, and interest on the Bonds.      
	  Reference is made to the Indenture for a description of the Trust    
Estate and for the provisions     
	  thereof with respect to the nature and extent of the security granted    
by the Issuer to the Trustee     
	  thereunder, the rights, duties, and obligations of the Issuer and the    
Trustee, the rights of the     
	  registered Owners of the Bonds, and the terms on which the Bonds    
are issued and secured, to all of     
	  which provisions, and to all other provisions of the Indenture, the    
Registered Owner hereof by the     
	  acceptance of this Bond assents.    
	      
	  I.	Weekly Rate Provisions    
	      
	  	Optional Tender.  During a Weekly Rate Period, this Bond    
or any portion thereof in     
	  Authorized Denominations (except during any period this Bond is a    
Pledged Bond or Company     
	  Bond) shall be purchased on the demand of the registered Owner    
thereof on any Business Day at     
	  a price equal to 100% of the principal amount thereof, plus accrued    
and unpaid interest thereon to     
	  the date of purchase, upon delivery to the tender agent duly    
appointed in accordance with the     
	  provisions of the Indenture (together with any successor tender    
agent, the "Tender Agent") at its     
	  Principal Office, on any Business Day, of (a) a written irrevocable    
notice setting forth the information     
	  required by the Indenture, including the date on which such Bond,    
or the portion thereof being     
	  tendered for purchase, shall be so purchased, which date shall be a    
Business Day not prior to the     
	  seventh day next succeeding the date of the delivery of such notice    
to the Tender Agent, together     
	  with (b) this Bond, as provided in the Indenture; provided, that if    
the registered Owner of the     
	  tendered Bond is an open-ended diversified management    
investment company (registered under the     
	  Investment Company Act of 1940, as amended), the delivery    
required under this clause (b) need not     
	  be made until the date such Bond is to be purchased from such    
registered Owner as provided in the     
	  Indenture.  Notwithstanding the foregoing, if the Bonds, are held in    
a Book-Entry System, separate     
	  procedures for the optional tender of Bonds are set forth in the    
Indenture.    
	      
	  	Interest.  During any period this Bond is in the Weekly Rate    
Mode, interest on this Bond shall     
	  be paid on the first Business Day of each month next succeeding    
the Closing Date (if applicable),     
	  each Weekly Rate Conversion Date, and on the Maturity Date    
specified above or such other date     
	  as the outstanding principal amount of the Bonds is paid in full if    
the Bonds are in the Weekly Rate     
	  Mode at such time (each, a "Weekly Rate Interest Payment    
Date"), and shall be computed on the     
	  basis of a 365- or 366-day year, for the actual number of days    
elapsed.  Interest on this Bond for each     
	  Weekly Interest Period shall be calculated as provided below and in    
the Indenture.  During each     
	  Weekly Rate Period, "Weekly Interest Period" shall mean the    
period from and including the first day     
	  of the Weekly Rate Period through and including the following    
Tuesday, and after the first Weekly     
	  Interest Period of each Weekly Rate Period, from and including    
Wednesday of each week through     
	  and including the following Tuesday, whether or not such days are    
Business Days, provided, however,     
	  the initial Weekly Interest Period shall commence on the Closing    
Date and end on the following     
	  Tuesday.    
	      
	  	On Tuesday (unless Tuesday is not a Business Day, then on    
the next preceding Monday; unless     
	  Monday and Tuesday are not Business Days, then on the next    
subsequent Wednesday, whether or     
	  not a Business Day) of each calendar week during a Weekly Rate    
Period, with respect to each     
	  Weekly Interest Period, the Remarketing Agent shall determine the    
Weekly Rate for the ensuing or     
	  current (in the case of determinations made on Wednesday)     
Weekly Interest Period.  The     
	  determination of the Weekly Rate by the Remarketing Agent shall    
be conclusive and binding.    
	      
	  	The Weekly Rate for each Weekly Interest Period    
determined by the Remarketing Agent shall     
	  be the lowest rate of interest which will, in the sole judgment of the    
Remarketing Agent, having due     
	  regard for prevailing financial market conditions, permit the Bonds    
to be remarketed at a price of par,     
	  plus accrued interest, on the first day of the applicable Weekly    
Interest Period; provided that in no     
	  case shall the Weekly Rate be more than the Maximum Rate.  In    
the event no Weekly Rate is     
	  determined by the Remarketing Agent for a Weekly Interest Period,    
the Weekly Rate for such     
	  Weekly Interest Period shall be the rate from time to time    
established pursuant to the Indenture.    
	      
	  II.	Daily Rate Provisions    
	      
	  	Optional Tender.  During a Daily Rate Period, this Bond or    
any portion thereof in Authorized     
	  Denominations (except during any period this Bond is a Pledged    
Bond or Company Bond) shall be     
	  purchased on the demand of the registered Owner thereof on any    
Business Day at a price equal to     
	  100% of the principal amount thereof, plus accrued and unpaid    
interest thereon to the date of     
	  purchase, upon delivery (by telecopy of otherwise) to the Tender    
Agent at its principal office, (a) by     
	  10:30 a.m., New York time, on such Business Day, of a written    
irrevocable notice, which will be     
	  effective upon receipt, setting forth the information required by the    
Indenture and (b) by 11:00 a.m.,     
	  New York time, on such Business Day, this Bond, as provided in    
the Indenture.  Notwithstanding the     
	  foregoing, if the Bonds are held in a Book-Entry System, separate    
procedures for the optional tender     
	  of Bonds are set forth in the Indenture.    
	      
	  	Interest.  During any period this Bond is in the Daily Rate    
Mode, interest on this Bond shall     
	  be paid on the first Business Day of each month next succeeding    
the Closing Date (if applicable),     
	  each Daily Rate Conversion Date, and on the Maturity Date    
specified above or such other date as     
	  the outstanding principal amount of the Bonds is paid in full if the    
Bonds are in the Daily Rate Mode     
	  at such time (each, a "Daily Rate Interest Payment Date"), and    
shall be computed on the basis of     
	  a 365- or 366-day year, for the actual number of days elapsed.     
Interest on the Bonds for each Daily     
	  Interest Period shall be calculated as provided below and in the    
Indenture.  During each Daily Rate     
	  Period, "Daily Interest Period" shall mean the period from and    
including the first day of the Daily     
	  Rate Period to but excluding the immediately succeeding Business    
Day.    
	      
	  	On  the first day of each Daily Interest Period, the    
Remarketing Agent shall determine the     
	  Daily Rate for such Daily Interest Period.  The determination of the    
Daily Rate by the Remarketing     
	  Agent shall be conclusive and binding.    
	      
	  	The Daily Rate for each Daily Interest Period determined by    
the Remarketing Agent shall be     
	  the lowest rate of interest which will, in the sole judgment of the    
Remarketing Agent, having due     
	  regard for prevailing financial market conditions, permit the Bonds    
to be remarketed at a price of par,     
	  plus accrued interest, on the first day of the applicable Daily    
Interest Period; provided that in no case     
	  shall the Daily Rate be more than the Maximum Rate.  In the event    
no Daily Rate is determined by     
	  the Remarketing Agent for a Daily Interest Period, then the Bonds    
shall thereupon bear interest at     
	  the last Daily Rate previously determined pursuant to the Indenture.    
	      
	  III. 	CP Rate Provisions    
	      
	  	From and after each CP Rate Conversion Date or a CP Rate    
Reset Date, as appropriate, to     
	  the earlier of their redemption, the following Conversion Date, or    
the following CP Rate Reset Date,     
	  the interest rate of this Bond shall be a CP Rate, determined as    
provided below and in the Indenture.      
	  When the Bonds are in the CP Rate Mode, in the case of each CP    
Rate Period, on the first day     
	  thereof, the Remarketing Agent shall determine (i) the duration of    
the CP Rate Period and (ii) the     
	  CP Rate which shall apply during such CP Rate Period.  The    
duration of the CP Rate Period so     
	  determined shall be that which, in the sole judgment of the    
Remarketing Agent will provide the     
	  lowest overall interest cost with respect to the Bonds, with due    
regard to prevailing financial market     
	  conditions, foreseeable changes in such conditions, the anticipated    
duration of the period the Bonds     
	  may remain in the CP Rate Mode, and such other factors which the    
Remarketing Agent, in its sole     
	  judgment, shall deem relevant and economically advantageous to    
consider.  Upon determination of     
	  the duration of the CP Rate Period, the Remarketing Agent shall    
determine the CP Rate which shall     
	  be in effect during such CP Rate Period, which shall be the lowest    
rate of interest which, in the sole     
	  judgment of the Remarketing Agent, having due regard to    
prevailing financial market conditions, will     
	  permit the Bonds to be sold at par, plus accrued interest, on the first    
day of such CP Rate Period.      
	  Notwithstanding the foregoing, the CP Rate so determined shall not    
be more than the Maximum     
	  Rate.  Unless and until the Company elects to effect a conversion of    
the Bonds from the CP Rate     
	  Mode to another Mode, the Remarketing Agent shall continually    
redetermine the duration of, and     
	  the CP Rate to be effective during each new CP Rate Period, which    
will commence, without further     
	  action on the part of the Company on each CP Rate Reset Date.  If    
on any CP Rate Reset Date the     
	  Remarketing Agent shall fail to determine either the duration of, or    
the CP Rate to be effective     
	  during the CP Rate Period which commences on such date, then,    
without further action on the part     
	  of the Company, the Bonds shall thereupon bear interest at the    
Weekly Rate determined pursuant     
	  to the Indenture.  Each determination by the Remarketing Agent    
shall be conclusive and binding.      
	  While the Bonds are in the CP Rate Mode, interest on this Bond    
will be payable on the first Business     
	  Day which follows each CP Rate Period, and shall be computed on    
the basis of a 365- or 366-day     
	  year, and the actual number of days elapsed.    
	      
	      
   
   
	  IV.	 Adjustable Rate Provisions    
	      
	  	From and after each Adjustable Rate Conversion Date or    
Adjustable Rate Reset Date, the     
	  interest rate on this Bond shall be an Adjustable Rate, determined    
as provided below and in the     
	  Indenture.  When the Bonds are in the Adjustable Rate Mode, the    
Bonds will remain in such Mode     
	  for as long as the Company continues to deliver timely conversion    
notices specifying the duration of     
	  the next Adjustable Rate Period.  The Remarketing Agent, on or    
prior to the commencement of each     
	  Adjustable Rate Period, shall determine the Adjustable Rate to be    
borne by the Bonds during such     
	  Adjustable Rate Period, which will be the lowest rate which, in its    
sole judgment having due regard     
	  for prevailing financial market conditions, will permit the Bonds to    
be sold at par on the first day of     
	  such Adjustable Rate Period.  Notwithstanding the foregoing, the    
Adjustable Rate shall not be more     
	  than the Maximum Rate.  In the event no Adjustable Rate is    
determined by the Remarketing Agent     
	  for an Adjustable Rate Period, then the Bonds shall bear interest as    
provided in the Indenture.    
	      
	  	During each Adjustable Rate Period, interest on this Bond    
shall be paid on each Adjustable     
	  Rate Interest Payment Date and shall be computed on the basis of a    
360-day year consisting of twelve     
	  30-day months.    
	      
	  V.	Conversion Provisions    
	      
	  	The interest rate Mode of this Bond shall be converted from    
one Mode to another Mode, or     
	  from an Adjustable Rate Period of one duration to an Adjustable    
Rate Period of the same or a     
	  different duration within the Adjustable Rate Mode, if the Company    
shall give notice as provided in     
	  the Indenture of its election to effect such conversion, specifying in    
such notice the date on which     
	  the Conversion Date will occur (which date shall be at least 25 days    
after such notice is given) and,     
	  if the conversion is to an Adjustable Rate Period, specifying the    
Interest Payment Date which shall     
	  be the day following the last day of such Adjustable Rate Period    
(which Adjustable Rate Period shall     
	  be of a duration of at least six months).  The Bonds shall be subject    
to mandatory tender and     
	  purchase on the Conversion Date.  In the event any condition    
precedent to the conversion of the     
	  interest rate Mode of this Bond from one Mode to another Mode, or    
from an Adjustable Rate     
	  Period of one duration to an Adjustable Rate Period of the same or    
a different duration, is not     
	  satisfied, this Bond shall nonetheless be subject to mandatory    
tender on the Conversion Date and the     
	  Bonds shall commence bearing interest on the Conversion Date as    
provided in the Indenture.    
	      
	  VI.	 Mandatory Tender    
	      
	  	All Bonds are subject to mandatory tender in whole by the    
Owners to the Tender Agent at its     
	  Principal Office on each date described below:    
	      
	  	(a)	On each Conversion Date;    
	      
	  	(b)	On each CP Rate Reset Date;    
	      
	  	(c)	On the second Business Day prior to the expiration    
or termination of the Letter of     
	  Credit (except as provided in the Indenture), if the Trustee has not    
received evidence satisfactory to     
	  it as required by the Indenture by the 25th day preceding the    
scheduled expiration or termination     
	  date of the Letter of Credit of either an extension of the then    
existing Letter of Credit or the     
	  issuance of an Alternate Credit Facility meeting the requirements    
set forth therefor in the     
	  Agreement, including the Maintenance of Rating requirement (as    
defined therein);     
	       
	  	(d)	On the date of substitution of an Alternate Credit    
Facility for the then existing Letter     
	  of Credit if the Trustee has not received evidence of a Maintenance    
of Rating with respect thereto     
	  by the 25th day preceding such substitution date;     
	      
	  	(e)	On each optional redemption date pursuant to the    
Indenture for which the Company     
	  has elected to purchase Bonds in lieu of optional redemption    
pursuant to the Indenture; and    
	      
	  	(f)	On the date on which the Guaranty is released as    
provided in the Indenture.    
	      
	  	The purchase price of Bonds subject to mandatory tender    
shall be 100% of the principal     
	  amount thereof (except in the case of a mandatory tender described    
in paragraph (c), (d), (e), or (f)     
	  above, during, but prior to the expiration date of, an Adjustable    
Rate Period, in which case the     
	  purchase price shall include a premium equal to the then applicable    
optional redemption premium,     
	  if any, on the Bonds, as set forth in the Indenture), plus accrued    
interest, if any, to the mandatory     
	  tender date.  Not later than 20 days prior to any mandatory tender    
date, the Trustee shall mail notice     
	  to all Owners of Bonds subject to mandatory tender on such date    
stating that (1) due to the     
	  occurrence of one of the events described above (which event shall    
be specified), such Owner"s     
	  Bonds will be subject to mandatory tender to the Tender Agent at    
its Principal Office on the     
	  mandatory tender date at the purchase price described above, and    
(2) interest with respect to Bonds     
	  which are not tendered on the mandatory tender date will cease to    
accrue provided Available Moneys     
	  for such purchase are on deposit with the Tender Agent on the    
mandatory tender date.  Notice of     
	  mandatory tenders described in paragraphs (a) and (e) above shall    
be given as part of the notice of     
	  conversion or optional redemption referenced above.  No failure on    
the part of the Tender Agent     
	  to give such notice shall affect the requirement that Bonds be    
tendered on the mandatory tender     
	  date.    
	      
	  	Any Bond subject to mandatory tender which is not    
tendered on or before the mandatory     
	  tender date shall, if Available Moneys sufficient and available for    
the purchase of such Bonds have     
	  been deposited with the Tender Agent on the mandatory tender    
date, be deemed to have been     
	  tendered for purchase on the mandatory tender date, and from and    
after such date, interest will no     
	  longer accrue on such Bonds.  Owners of such Bonds shall have no    
rights or benefits under the     
	  Indenture with respect to such Bonds other than to receive the    
purchase price for such Bonds upon     
	  surrender of such Bonds to the Tender Agent.    
	      
	  VII.	 Redemption of Bonds    
	      
	  	The Bonds shall be subject to optional redemption only as    
follows:    
	      
	  	a.	Weekly Rate Mode, CP Rate Mode, or Daily Rate    
Mode.  While the Bonds are in the     
	  Weekly Rate Mode or the Daily Rate Mode, they are subject to    
optional redemption, in whole or     
	  in part on any Business Day in Authorized Denominations, and    
while the Bonds are in the CP Rate     
	  Mode, they are subject to optional redemption in whole or in part in    
Authorized Denominations on     
	  any Interest Payment Date, at the direction of the Company, at a    
redemption price equal to 100%     
	  of the principal amount of the Bond to be redeemed, plus accrued    
interest thereon to the redemption     
	  date.    
	      
	  	b.	Adjustable Rate Mode.     While the Bonds are in    
the Adjustable Rate Mode, they are     
	  subject to optional redemption in whole or in part on any date, at    
the direction of the Company, only     
	  on the dates and at the applicable redemption prices set forth in the    
Indenture.    
	       
	  	While the Bonds are in the Adjustable Rate Mode or the CP    
Rate Mode, the Bonds are     
	  subject to extraordinary optional redemption in whole on any date    
at a redemption price equal to the     
	  principal amount of Bonds plus accrued interest to the redemption    
date, without premium, upon the     
	  occurrence of certain events specified in the Indenture.    
	      
	  	The Bonds in any Mode are subject to mandatory    
redemption in whole on the next date for     
	  which timely notice of redemption can be given by the Trustee after    
the occurrence of a     
	  Determination of Taxability at a redemption price equal to the    
aggregate principal amount of the     
	  Bonds plus accrued interest thereon to the redemption date, without    
premium.    
	      
	  	At least 30 days prior to any redemption of Bonds, the    
Trustee shall cause notice of the call     
	  for redemption to be sent by first class mail, postage prepaid, to the    
Owner of each Bond to be     
	  redeemed at the address of such Owner shown on the registration    
books maintained by the Trustee.      
	  Neither the failure to give any such notice nor any defect in any    
notice so mailed shall affect the     
	  sufficiency or the validity of any proceedings for the redemption of    
the Bonds.    
	      
	  	If Available Moneys are deposited in the Bond Fund on the    
date Bonds are to be redeemed,     
	  Bonds or portions thereof redeemed shall no longer be secured by    
this Indenture and shall not be     
	  deemed to be outstanding under the provisions of this Indenture.     
Interest shall not continue to     
	  accrue on the Bonds after the date fixed for redemption, so long as    
Available Moneys are on deposit     
	  to pay all principal of, premium, if any, and interest accrued on the    
Bonds on such date.  However,     
	  if Available Moneys shall not be on deposit on the redemption date,    
such Bonds or portions thereof     
	  shall continue to bear interest until paid at the same rate as they    
would have borne had they not been     
	  called for redemption.    
	      
	  	Any partial redemption of Bonds shall be made only in    
integral multiples of $100,000.  If fewer     
	  than all of the Bonds shall be called for redemption, the portion of    
Bonds to be redeemed shall be     
	  selected by the Trustee as provided in the Indenture.    
	      
	  VIII.	General Provisions    
	      
	  	Except as provided in the Indenture, the Ownership of this    
Bond may be transferred (in     
	  Authorized Denominations) only upon presentation and surrender    
of this Bond at the corporate trust     
	  office of the Trustee, together with an assignment duly executed by    
the Registered Owner hereof or     
	  his duly authorized attorney-in-fact in such form as shall be    
satisfactory to the Trustee.    
	      
	  	Provisions may be made for the payment of amounts    
represented by the Bonds as provided in     
	  the Indenture, in which event all liability of the Issuer to the    
Owners of the applicable Bonds for the     
	  payment of such Bonds shall forthwith cease, terminate, and be    
completely discharged, and thereupon     
	  it shall be the duty of the Trustee to hold such funds (but only for    
the period specified and as     
	  provided in the Indenture), without liability for interest thereon, for    
the benefit of the Owners of     
	  such Bonds, who shall thereafter be restricted exclusively to such    
funds for any claims of whatever     
	  nature under the Indenture or on, or with respect to, said Bonds.    
	      
	  	It is hereby certified and covenanted that this Bond has been    
duly and validly authorized,     
	  issued, and delivered; that all acts, conditions, and things required    
or proper to be performed, exist     
	  and be done precedent to or in the authorization, issuance, and    
delivery of this Bond have been     
	  performed, exist, and have been done in accordance with law.    
	       
	  	The Bonds are secured by the Indenture, whereunder the    
Trustee undertakes to enforce the     
	  rights of the Owners of the Bonds and to perform other duties to the    
extent and under the conditions     
	  stated in the Indenture.  In case an Event of Default shall occur, the    
principal of and interest on the     
	  Bonds then outstanding may, and, under certain circumstances,    
shall, be declared to be due and     
	  payable immediately upon the conditions and in the manner    
provided in the Indenture.  Under the     
	  circumstances and conditions provided in the Indenture, the    
Trustee may, or shall, waive any Event     
	  of Default under the Indenture and its consequences.    
	      
	  	The Issuer has reserved the right to amend the Indenture,    
with the consent of the Bank, as     
	  provided therein.  Under some (but not all) circumstances,    
amendments thereto must also be     
	  approved by the Owners of either at least a majority or 100% in    
aggregate principal amount of the     
	  outstanding Bonds.

	  A SPECIAL AND LIMITED OBLIGATION OF THE ISSUER

	  by such Owner prior to such Record Date.  Registered Owners of    
$1,000,000 or more in aggregate     
	  principal amount of Bonds shall be entitled to receive interest    
payments by wire transfer by providing     
	  written wire instructions to the Trustee before the Record Date.    
	      
	  	This Bond is authorized and issued under and pursuant to    
authority conferred by the Act,     
	  certain proceedings of the Board of Directors of the Issuer and the    
Indenture of Trust dated as of     
	  April 1, 1994 (the "Indenture") between the Issuer and the    
Trustee.  Certain terms used and not     
	  defined in this Bond are defined in the Indenture.  This Bond is one    
of the Issuer"s duly authorized     
	  Industrial Development Revenue Bonds, Series 1994 (Trencor    
Jetco, Inc. Project) (the "Bonds"),     
	  which Bonds have been issued in the aggregate principal amount of    
$8,000,000 to provide funds to     
	  make a loan to Trencor Jetco, Inc., a Texas corporation (the    
"Company") pursuant to a Loan     
	  Agreement dated as of April 1, 1994 (the "Agreement") between    
the Issuer and the Company.  The     
	  proceeds of the Bonds will be used to finance a portion of the costs    
of acquisition, construction and     
	  equipping of certain facilities (the "Project") located in the Unit.     
As security for the payment of the     
	  Bonds, the Company has caused to be delivered to the Trustee a    
letter of credit (the "Initial Letter     
	  of Credit") of The First National Bank of Chicago (the "Bank"),    
against which the Trustee shall be     
	  entitled to draw, in accordance with the terms thereof, to pay when    
and as due, the principal or     
	  purchase price of, and interest on, the Bonds during the term of the    
Initial Letter of Credit.  Under     
	  certain conditions, the Company may cause to be delivered an    
Alternate Credit Facility (an     
	  "Alternate Credit Facility") in substitution for the Letter of    
Credit then in effect without the consent     
	  of the Owners of the Bonds.  The Initial Letter of Credit, together    
with any Alternate Credit Facility,     
	  is hereinafter referred to as the "Letter of Credit".  The Bonds are    
guaranteed by Astec Industries,     
	  Inc., a Tennessee corporation (the "Guarantor"), the owner of 100%    
of the outstanding stock of the     
	  Company, pursuant to a Guaranty Agreement dated April 1, 1994,    
between the Guarantor and the     
	  Trustee.  The Bonds are not secured by any lien on or security    
interest in the Project.    
	      
	  	The Bonds are issued under and entitled to the benefits of    
the Indenture.  Pursuant to the     
	  Indenture, the Issuer has pledged and assigned to the Trustee the    
Trust Estate as security for its     
	  obligation to pay the principal or purchase price of, premium, if    
any, and interest on the Bonds.      
	  Reference is made to the Indenture for a description of the Trust    
Estate and for the provisions     
	  thereof with respect to the nature and extent of the security granted    
by the Issuer to the Trustee     
	  thereunder, the rights, duties, and obligations of the Issuer and the    
Trustee, the rights of the     
	  registered Owners of the Bonds, and the terms on which the Bonds    
are issued and secured, to all of     
	  which provisions, and to all other provisions of the Indenture, the    
Registered Owner hereof by the     
	  acceptance of this Bond assents.    
	      
	  I.	Weekly Rate Provisions    
	      
	  	Optional Tender.  During a Weekly Rate Period, this Bond    
or any portion thereof in     
	  Authorized Denominations (except during any period this Bond is a    
Pledged Bond or Company     
	  Bond) shall be purchased on the demand of the registered Owner    
thereof on any Business Day at     
	  a price equal to 100% of the principal amount thereof, plus accrued    
and unpaid interest thereon to     
	  the date of purchase, upon delivery to the tender agent duly    
appointed in accordance with the     
	  provisions of the Indenture (together with any successor tender    
agent, the "Tender Agent") at its     
	  Principal Office, on any Business Day, of (a) a written irrevocable    
notice setting forth the information     
	  required by the Indenture, including the date on which such Bond,    
or the portion thereof being     
	  tendered for purchase, shall be so purchased, which date shall be a    
Business Day not prior to the     
	  seventh day next succeeding the date of the delivery of such notice    
to the Tender Agent, together     
	  with (b) this Bond, as provided in the Indenture; provided, that if    
the registered Owner of the     
	  tendered Bond is an open-ended diversified management    
investment company (registered under the     
	  Investment Company Act of 1940, as amended), the delivery    
required under this clause (b) need not     
	  be made until the date such Bond is to be purchased from such    
registered Owner as provided in the     
	  Indenture.  Notwithstanding the foregoing, if the Bonds, are held in    
a Book-Entry System, separate     
	  procedures for the optional tender of Bonds are set forth in the    
Indenture.    
	      
	  	Interest.  During any period this Bond is in the Weekly Rate    
Mode, interest on this Bond shall     
	  be paid on the first Business Day of each month next succeeding    
the Closing Date (if applicable),     
	  each Weekly Rate Conversion Date, and on the Maturity Date    
specified above or such other date     
	  as the outstanding principal amount of the Bonds is paid in full if    
the Bonds are in the Weekly Rate     
	  Mode at such time (each, a "Weekly Rate Interest Payment    
Date"), and shall be computed on the     
	  basis of a 365- or 366-day year, for the actual number of days    
elapsed.  Interest on this Bond for each     
	  Weekly Interest Period shall be calculated as provided below and in    
the Indenture.  During each     
	  Weekly Rate Period, "Weekly Interest Period" shall mean the    
period from and including the first day     
	  of the Weekly Rate Period through and including the following    
Tuesday, and after the first Weekly     
	  Interest Period of each Weekly Rate Period, from and including    
Wednesday of each week through     
	  and including the following Tuesday, whether or not such days are    
Business Days, provided, however,     
	  the initial Weekly Interest Period shall commence on the Closing    
Date and end on the following     
	  Tuesday.    
	      
	  	On Tuesday (unless Tuesday is not a Business Day, then on    
the next preceding Monday; unless     
	  Monday and Tuesday are not Business Days, then on the next    
subsequent Wednesday, whether or     
	  not a Business Day) of each calendar week during a Weekly Rate    
Period, with respect to each     
	  Weekly Interest Period, the Remarketing Agent shall determine the    
Weekly Rate for the ensuing or     
	  current (in the case of determinations made on Wednesday)     
Weekly Interest Period.  The     
	  determination of the Weekly Rate by the Remarketing Agent shall    
be conclusive and binding.    
	      
	  	The Weekly Rate for each Weekly Interest Period    
determined by the Remarketing Agent shall     
	  be the lowest rate of interest which will, in the sole judgment of the    
Remarketing Agent, having due     
	  regard for prevailing financial market conditions, permit the Bonds    
to be remarketed at a price of par,     
	  plus accrued interest, on the first day of the applicable Weekly    
Interest Period; provided that in no     
	  case shall the Weekly Rate be more than the Maximum Rate.  In    
the event no Weekly Rate is     
	  determined by the Remarketing Agent for a Weekly Interest Period,    
the Weekly Rate for such     
	  Weekly Interest Period shall be the rate from time to time    
established pursuant to the Indenture.    
	      
	  II.	Daily Rate Provisions    
	      
	  	Optional Tender.  During a Daily Rate Period, this Bond or    
any portion thereof in Authorized     
	  Denominations (except during any period this Bond is a Pledged    
Bond or Company Bond) shall be     
	  purchased on the demand of the registered Owner thereof on any    
Business Day at a price equal to     
	  100% of the principal amount thereof, plus accrued and unpaid    
interest thereon to the date of     
	  purchase, upon delivery (by telecopy of otherwise) to the Tender    
Agent at its principal office, (a) by     
	  10:30 a.m., New York time, on such Business Day, of a written    
irrevocable notice, which will be     
	  effective upon receipt, setting forth the information required by the    
Indenture and (b) by 11:00 a.m.,     
	  New York time, on such Business Day, this Bond, as provided in    
the Indenture.  Notwithstanding the     
	  foregoing, if the Bonds are held in a Book-Entry System, separate    
procedures for the optional tender     
	  of Bonds are set forth in the Indenture.    
	      
	  	Interest.  During any period this Bond is in the Daily Rate    
Mode, interest on this Bond shall     
	  be paid on the first Business Day of each month next succeeding    
the Closing Date (if applicable),     
	  each Daily Rate Conversion Date, and on the Maturity Date    
specified above or such other date as     
	  the outstanding principal amount of the Bonds is paid in full if the    
Bonds are in the Daily Rate Mode     
	  at such time (each, a "Daily Rate Interest Payment Date"), and    
shall be computed on the basis of     
	  a 365- or 366-day year, for the actual number of days elapsed.     
Interest on the Bonds for each Daily     
	  Interest Period shall be calculated as provided below and in the    
Indenture.  During each Daily Rate     
	  Period, "Daily Interest Period" shall mean the period from and    
including the first day of the Daily     
	  Rate Period to but excluding the immediately succeeding Business    
Day.    
	      
	  	On  the first day of each Daily Interest Period, the    
Remarketing Agent shall determine the     
	  Daily Rate for such Daily Interest Period.  The determination of the    
Daily Rate by the Remarketing     
	  Agent shall be conclusive and binding.    
	      
	  	The Daily Rate for each Daily Interest Period determined by    
the Remarketing Agent shall be     
	  the lowest rate of interest which will, in the sole judgment of the    
Remarketing Agent, having due     
	  regard for prevailing financial market conditions, permit the Bonds    
to be remarketed at a price of par,     
	  plus accrued interest, on the first day of the applicable Daily    
Interest Period; provided that in no case     
	  shall the Daily Rate be more than the Maximum Rate.  In the event    
no Daily Rate is determined by     
	  the Remarketing Agent for a Daily Interest Period, then the Bonds    
shall thereupon bear interest at     
	  the last Daily Rate previously determined pursuant to the Indenture.    
	      
	  III. 	CP Rate Provisions    
	      
	  	From and after each CP Rate Conversion Date or a CP Rate    
Reset Date, as appropriate, to     
	  the earlier of their redemption, the following Conversion Date, or    
the following CP Rate Reset Date,     
	  the interest rate of this Bond shall be a CP Rate, determined as    
provided below and in the Indenture.      
	  When the Bonds are in the CP Rate Mode, in the case of each CP    
Rate Period, on the first day     
	  thereof, the Remarketing Agent shall determine (i) the duration of    
the CP Rate Period and (ii) the     
	  CP Rate which shall apply during such CP Rate Period.  The    
duration of the CP Rate Period so     
	  determined shall be that which, in the sole judgment of the    
Remarketing Agent will provide the     
	  lowest overall interest cost with respect to the Bonds, with due    
regard to prevailing financial market     
	  conditions, foreseeable changes in such conditions, the anticipated    
duration of the period the Bonds     
	  may remain in the CP Rate Mode, and such other factors which the    
Remarketing Agent, in its sole     
	  judgment, shall deem relevant and economically advantageous to    
consider.  Upon determination of     
	  the duration of the CP Rate Period, the Remarketing Agent shall    
determine the CP Rate which shall     
	  be in effect during such CP Rate Period, which shall be the lowest    
rate of interest which, in the sole     
	  judgment of the Remarketing Agent, having due regard to    
prevailing financial market conditions, will     
	  permit the Bonds to be sold at par, plus accrued interest, on the first    
day of such CP Rate Period.      
	  Notwithstanding the foregoing, the CP Rate so determined shall not    
be more than the Maximum     
	  Rate.  Unless and until the Company elects to effect a conversion of    
the Bonds from the CP Rate     
	  Mode to another Mode, the Remarketing Agent shall continually    
redetermine the duration of, and     
	  the CP Rate to be effective during each new CP Rate Period, which    
will commence, without further     
	  action on the part of the Company on each CP Rate Reset Date.  If    
on any CP Rate Reset Date the     
	  Remarketing Agent shall fail to determine either the duration of, or    
the CP Rate to be effective     
	  during the CP Rate Period which commences on such date, then,    
without further action on the part     
	  of the Company, the Bonds shall thereupon bear interest at the    
Weekly Rate determined pursuant     
	  to the Indenture.  Each determination by the Remarketing Agent    
shall be conclusive and binding.      
	  While the Bonds are in the CP Rate Mode, interest on this Bond    
will be payable on the first Business     
	  Day which follows each CP Rate Period, and shall be computed on    
the basis of a 365- or 366-day     
	  year, and the actual number of days elapsed.    
	      
	  IV.	 Adjustable Rate Provisions    
	      
	  	From and after each Adjustable Rate Conversion Date or    
Adjustable Rate Reset Date, the     
	  interest rate on this Bond shall be an Adjustable Rate, determined    
as provided below and in the     
	  Indenture.  When the Bonds are in the Adjustable Rate Mode, the    
Bonds will remain in such Mode     
	  for as long as the Company continues to deliver timely conversion    
notices specifying the duration of     
	  the next Adjustable Rate Period.  The Remarketing Agent, on or    
prior to the commencement of each     
	  Adjustable Rate Period, shall determine the Adjustable Rate to be    
borne by the Bonds during such     
	  Adjustable Rate Period, which will be the lowest rate which, in its    
sole judgment having due regard     
	  for prevailing financial market conditions, will permit the Bonds to    
be sold at par on the first day of     
	  such Adjustable Rate Period.  Notwithstanding the foregoing, the    
Adjustable Rate shall not be more     
	  than the Maximum Rate.  In the event no Adjustable Rate is    
determined by the Remarketing Agent     
	  for an Adjustable Rate Period, then the Bonds shall bear interest as    
provided in the Indenture.    
	      
	  	During each Adjustable Rate Period, interest on this Bond    
shall be paid on each Adjustable     
	  Rate Interest Payment Date and shall be computed on the basis of a    
360-day year consisting of twelve     
	  30-day months.    
	      
	  V.	Conversion Provisions    
	      
	  	The interest rate Mode of this Bond shall be converted from    
one Mode to another Mode, or     
	  from an Adjustable Rate Period of one duration to an Adjustable    
Rate Period of the same or a     
	  different duration within the Adjustable Rate Mode, if the Company    
shall give notice as provided in     
	  the Indenture of its election to effect such conversion, specifying in    
such notice the date on which     
	  the Conversion Date will occur (which date shall be at least 25 days    
after such notice is given) and,     
	  if the conversion is to an Adjustable Rate Period, specifying the    
Interest Payment Date which shall     
	  be the day following the last day of such Adjustable Rate Period    
(which Adjustable Rate Period shall     
	  be of a duration of at least six months).  The Bonds shall be subject    
to mandatory tender and     
	  purchase on the Conversion Date.  In the event any condition    
precedent to the conversion of the     
	  interest rate Mode of this Bond from one Mode to another Mode, or    
from an Adjustable Rate     
	  Period of one duration to an Adjustable Rate Period of the same or    
a different duration, is not     
	  satisfied, this Bond shall nonetheless be subject to mandatory    
tender on the Conversion Date and the     
	  Bonds shall commence bearing interest on the Conversion Date as    
provided in the Indenture.    
	      
	  VI.	 Mandatory Tender    
	      
	  	All Bonds are subject to mandatory tender in whole by the    
Owners to the Tender Agent at its     
	  Principal Office on each date described below:    
	      
	  	(a)	On each Conversion Date;    
	      
	  	(b)	On each CP Rate Reset Date;    
	      
	  	(c)	On the second Business Day prior to the expiration    
or termination of the Letter of     
	  Credit (except as provided in the Indenture), if the Trustee has not    
received evidence satisfactory to     
	  it as required by the Indenture by the 25th day preceding the    
scheduled expiration or termination     
	  date of the Letter of Credit of either an extension of the then    
existing Letter of Credit or the     
	  issuance of an Alternate Credit Facility meeting the requirements    
set forth therefor in the     
	  Agreement, including the Maintenance of Rating requirement (as    
defined therein);     
	      
	  	(d)	On the date of substitution of an Alternate Credit    
Facility for the then existing Letter     
	  of Credit if the Trustee has not received evidence of a Maintenance    
of Rating with respect thereto     
	  by the 25th day preceding such substitution date;     
	      
	  	(e)	On each optional redemption date pursuant to the    
Indenture for which the Company     
	  has elected to purchase Bonds in lieu of optional redemption    
pursuant to the Indenture; and    
	      
	  	(f)	On the date on which the Guaranty is released as    
provided in the Indenture.    
	      
	  	The purchase price of Bonds subject to mandatory tender    
shall be 100% of the principal     
	  amount thereof (except in the case of a mandatory tender described    
in paragraph (c), (d), (e), or (f)     
	  above, during, but prior to the expiration date of, an Adjustable    
Rate Period, in which case the     
	  purchase price shall include a premium equal to the then applicable    
optional redemption premium,     
	  if any, on the Bonds, as set forth in the Indenture), plus accrued    
interest, if any, to the mandatory     
	  tender date.  Not later than 20 days prior to any mandatory tender    
date, the Trustee shall mail notice     
	  to all Owners of Bonds subject to mandatory tender on such date    
stating that (1) due to the     
	  occurrence of one of the events described above (which event shall    
be specified), such Owner"s     
	  Bonds will be subject to mandatory tender to the Tender Agent at    
its Principal Office on the     
	  mandatory tender date at the purchase price described above, and    
(2) interest with respect to Bonds     
	  which are not tendered on the mandatory tender date will cease to    
accrue provided Available Moneys     
	  for such purchase are on deposit with the Tender Agent on the    
mandatory tender date.  Notice of     
	  mandatory tenders described in paragraphs (a) and (e) above shall    
be given as part of the notice of     
	  conversion or optional redemption referenced above.  No failure on    
the part of the Tender Agent     
	  to give such notice shall affect the requirement that Bonds be    
tendered on the mandatory tender     
	  date.    
	      
	  	Any Bond subject to mandatory tender which is not    
tendered on or before the mandatory     
	  tender date shall, if Available Moneys sufficient and available for    
the purchase of such Bonds have     
	  been deposited with the Tender Agent on the mandatory tender    
date, be deemed to have been     
	  tendered for purchase on the mandatory tender date, and from and    
after such date, interest will no     
	  longer accrue on such Bonds.  Owners of such Bonds shall have no    
rights or benefits under the     
	  Indenture with respect to such Bonds other than to receive the    
purchase price for such Bonds upon     
	  surrender of such Bonds to the Tender Agent.    
	      
	  VII.	 Redemption of Bonds    
	      
	  	The Bonds shall be subject to optional redemption only as    
follows:    
	      
	  	a.	Weekly Rate Mode, CP Rate Mode, or Daily Rate    
Mode.  While the Bonds are in the     
	  Weekly Rate Mode or the Daily Rate Mode, they are subject to    
optional redemption, in whole or     
	  in part on any Business Day in Authorized Denominations, and    
while the Bonds are in the CP Rate     
	  Mode, they are subject to optional redemption in whole or in part in    
Authorized Denominations on     
	  any Interest Payment Date, at the direction of the Company, at a    
redemption price equal to 100%     
	  of the principal amount of the Bond to be redeemed, plus accrued    
interest thereon to the redemption     
	  date.     
	  	b.	Adjustable Rate Mode.     While the Bonds are in    
the Adjustable Rate Mode, they are     
	  subject to optional redemption in whole or in part on any date, at    
the direction of the Company, only     
	  on the dates and at the applicable redemption prices set forth in the    
Indenture.    
	      
	  	While the Bonds are in the Adjustable Rate Mode or the CP    
Rate Mode, the Bonds are     
	  subject to extraordinary optional redemption in whole on any date    
at a redemption price equal to the     
	  principal amount of Bonds plus accrued interest to the redemption    
date, without premium, upon the     
	  occurrence of certain events specified in the Indenture.    
	      
	  	The Bonds in any Mode are subject to mandatory    
redemption in whole on the next date for     
	  which timely notice of redemption can be given by the Trustee after    
the occurrence of a     
	  Determination of Taxability at a redemption price equal to the    
aggregate principal amount of the     
	  Bonds plus accrued interest thereon to the redemption date, without    
premium.    
	      
	  	At least 30 days prior to any redemption of Bonds, the    
Trustee shall cause notice of the call     
	  for redemption to be sent by first class mail, postage prepaid, to the    
Owner of each Bond to be     
	  redeemed at the address of such Owner shown on the registration    
books maintained by the Trustee.      
	  Neither the failure to give any such notice nor any defect in any    
notice so mailed shall affect the     
	  sufficiency or the validity of any proceedings for the redemption of    
the Bonds.    
	      
	  	If Available Moneys are deposited in the Bond Fund on the    
date Bonds are to be redeemed,     
	  Bonds or portions thereof redeemed shall no longer be secured by    
this Indenture and shall not be     
	  deemed to be outstanding under the provisions of this Indenture.     
Interest shall not continue to     
	  accrue on the Bonds after the date fixed for redemption, so long as    
Available Moneys are on deposit     
	  to pay all principal of, premium, if any, and interest accrued on the    
Bonds on such date.  However,     
	  if Available Moneys shall not be on deposit on the redemption date,    
such Bonds or portions thereof     
	  shall continue to bear interest until paid at the same rate as they    
would have borne had they not been     
	  called for redemption.    
	      
	  	Any partial redemption of Bonds shall be made only in    
integral multiples of $100,000.  If fewer     
	  than all of the Bonds shall be called for redemption, the portion of    
Bonds to be redeemed shall be     
	  selected by the Trustee as provided in the Indenture.

	  office of the Trustee, together with an assignment duly executed by    
the Registered Owner hereof or     
	  his duly authorized attorney-in-fact in such form as shall be    
satisfactory to the Trustee.    
	      
	  	Provisions may be made for the payment of amounts    
represented by the Bonds as provided in     
	  the Indenture, in which event all liability of the Issuer to the    
Owners of the applicable Bonds for the     
	  payment of such Bonds shall forthwith cease, terminate, and be    
completely discharged, and thereupon     
	  it shall be the duty of the Trustee to hold such funds (but only for    
the period specified and as     
	  provided in the Indenture), without liability for interest thereon, for    
the benefit of the Owners of     
	  such Bonds, who shall thereafter be restricted exclusively to such    
funds for any claims of whatever     
	  nature under the Indenture or on, or with respect to, said Bonds.    
	      
	  	It is hereby certified and covenanted that this Bond has been    
duly and validly authorized,     
	  issued, and delivered; that all acts, conditions, and things required

principal of and interest on the     
	  Bonds then outstanding may, and, under certain circumstances,    
shall, be declared to be due and     
	  payable immediately upon the conditions and in the manner    
provided in the Indenture.  Under the     
	  circumstances and conditions provided in the Indenture, the    
Trustee may, or shall, waive any Event     
	  of Default under the Indenture and its consequences.    
	      
	  	The Issuer has reserved the right to amend the Indenture,    
with the consent of the Bank, as     
	  provided therein.  Under some (but not all) circumstances,    
amendments thereto must also be     
	  approved by the Owners of either at least a majority or 100% in    
aggregate principal amount of the     
	  outstanding Bonds.

of the Issuer"s duly authorized     
	  Industrial Development Revenue Bonds, Series 1994 (Trencor

"Company") pursuant to a Loan     
	  Agreement dated as of April 1, 1994 (the "Agreement") between

	  Bonds, the Company has caused to be delivered to the Trustee a    
letter of credit (the "Initial Letter     
	  of Credit") of The First National Bank of Chicago (the "Bank"),

Initial Letter of Credit.  Under     
	  certain conditions, the Company may cause to be delivered an    
Alternate Credit Facility (an     
	  "Alternate Credit Facility") in substitution for the Letter of    
Credit then in effect without the consent     
	  of the Owners of the Bonds.  The Initial Letter of Credit, together    
with any Alternate Credit Facility,     
	  is hereinafter referred to as the "Letter of Credit".  The Bonds are

	  Inc., a Tennessee corporation (the "Guarantor"), the owner of 100%

	  Company, pursuant to a Guaranty Agreement dated April 1, 1994,    
between the Guarantor and the     
	  Trustee.  The Bonds are not secured by any lien on or security    
interest in the Project.    
	      
	  	The Bonds are issued under and entitled to the benefits of    
the Indenture.  Pursuant to the     
	  Indenture, the Issuer has pledged and assigned to the Trustee the    
Trust Estate as security for its     
	  obligation to pay the principal or purchase price of, premium, if    
any, and interest on the Bonds.      
	  Reference is made to the Indenture for a description of the Trust    
Estate and for the provisions     
	  thereof with respect to the nature and extent of the security granted    
by the Issuer to the Trustee     
	  thereunder, the rights, duties, and obligations of the Issuer and the    
Trustee, the rights of the     
	  registered Owners of the Bonds, and the terms on which the Bonds    
are issued and secured, to all of     
	  which provisions, and to all other provisions of the Indenture, the    
Registered Owner hereof by the     
	  acceptance of this Bond assents.    
	      
	      
   
   
	  I.	Weekly Rate Provisions    
	      
	  	Optional Tender.  During a Weekly Rate Period, this Bond    
or any portion thereof in     
	  Authorized Denominations (except during any period this Bond is a    
Pledged Bond or Company     
	  Bond) shall be purchased on the demand of the registered Owner    
thereof on any Business Day at     
	  a price equal to 100% of the principal amount thereof, plus accrued    
and unpaid interest thereon to     
	  the date of purchase, upon delivery to the tender agent duly    
appointed in accordance with the     
	  provisions of the Indenture (together with any successor tender    
agent, the "Tender Agent") at its     
	  Principal Office, on any Business Day, of (a) a written irrevocable    
notice setting forth the information     
	  required by the Indenture, including the date on which such Bond,    
or the portion thereof being     
	  tendered for purchase, shall be so purchased, which date shall be a    
Business Day not prior to the     
	  seventh day next succeeding the date of the delivery of such notice    
to the Tender Agent, together     
	  with (b) this Bond, as provided in the Indenture; provided, that if    
the registered Owner of the     
	  tendered Bond is an open-ended diversified management    
investment company (registered under the     
	  Investment Company Act of 1940, as amended), the delivery    
required under this clause (b) need not     
	  be made until the date such Bond is to be purchased from such    
registered Owner as provided in the     
	  Indenture.  Notwithstanding the foregoing, if the Bonds, are held in    
a Book-Entry System, separate     
	  procedures for the optional tender of Bonds are set forth in the    
Indenture.    
	      
	  	Interest.  During any period this Bond is in the Weekly Rate    
Mode, interest on this Bond shall     
	  be paid on the first Business Day of each month next succeeding    
the Closing Date (if applicable),     
	  each Weekly Rate Conversion Date, and on the Maturity Date    
specified above or such other date     
	  as the outstanding principal amount of the Bonds is paid in full if    
the Bonds are in the Weekly Rate     
	  Mode at such time (each, a "Weekly Rate Interest Payment    
Date"), and shall be computed on the     
	  basis of a 365- or 366-day year, for the actual number of days    
elapsed.  Interest on this Bond for each     
	  Weekly Interest Period shall be calculated as provided below and in    
the Indenture.  During each     
	  Weekly Rate Period, "Weekly Interest Period" shall mean the    
period from and including the first day     
	  of the Weekly Rate Period through and including the following    
Tuesday, and after the first Weekly     
	  Interest Period of each Weekly Rate Period, from and including    
Wednesday of each week through     
	  and including the following Tuesday, whether or not such days are    
Business Days, provided, however,     
	  the initial Weekly Interest Period shall commence on the Closing    
Date and end on the following     
	  Tuesday.    
	      
	  	On Tuesday (unless Tuesday is not a Business Day, then on    
the next preceding Monday; unless     
	  Monday and Tuesday are not Business Days, then on the next    
subsequent Wednesday, whether or     
	  not a Business Day) of each calendar week during a Weekly Rate    
Period, with respect to each     
	  Weekly Interest Period, the Remarketing Agent shall determine the    
Weekly Rate for the ensuing or     
	  current (in the case of determinations made on Wednesday)     
Weekly Interest Period.  The     
	  determination of the Weekly Rate by the Remarketing Agent shall    
be conclusive and binding.    
	      
	  	The Weekly Rate for each Weekly Interest Period    
determined by the Remarketing Agent shall     
	  be the lowest rate of interest which will, in the sole judgment of the    
Remarketing Agent, having due     
	  regard for prevailing financial market conditions, permit the Bonds    
to be remarketed at a price of par,     
	  plus accrued interest, on the first day of the applicable Weekly    
Interest Period; provided that in no     
	  case shall the Weekly Rate be more than the Maximum Rate.  In    
the event no Weekly Rate is     
	  determined by the Remarketing Agent for a Weekly Interest Period,    
the Weekly Rate for such     
	  Weekly Interest Period shall be the rate from time to time    
established pursuant to the Indenture.    
	      
	      
   
   
	  II.	Daily Rate Provisions    
	      
	  	Optional Tender.  During a Daily Rate Period, this Bond or    
any portion thereof in Authorized     
	  Denominations (except during any period this Bond is a Pledged    
Bond or Company Bond) shall be     
	  purchased on the demand of the registered Owner thereof on any    
Business Day at a price equal to     
	  100% of the principal amount thereof, plus accrued and unpaid    
interest thereon to the date of     
	  purchase, upon delivery (by telecopy of otherwise) to the Tender    
Agent at its principal office, (a) by     
	  10:30 a.m., New York time, on such Business Day, of a written    
irrevocable notice, which will be     
	  effective upon receipt, setting forth the information required by the    
Indenture and (b) by 11:00 a.m.,     
	  New York time, on such Business Day, this Bond, as provided in    
the Indenture.  Notwithstanding the     
	  foregoing, if the Bonds are held in a Book-Entry System, separate    
procedures for the optional tender     
	  of Bonds are set forth in the Indenture.    
	      
	  	Interest.  During any period this Bond is in the Daily Rate    
Mode, interest on this Bond shall     
	  be paid on the first Business Day of each month next succeeding    
the Closing Date (if applicable),     
	  each Daily Rate Conversion Date, and on the Maturity Date    
specified above or such other date as     
	  the outstanding principal amount of the Bonds is paid in full if the    
Bonds are in the Daily Rate Mode     
	  at such time (each, a "Daily Rate Interest Payment Date"), and    
shall be computed on the basis of     
	  a 365- or 366-day year, for the actual number of days elapsed.     
Interest on the Bonds for each Daily     
	  Interest Period shall be calculated as provided below and in the    
Indenture.  During each Daily Rate     
	  Period, "Daily Interest Period" shall mean the period from and    
including the first day of the Daily     
	  Rate Period to but excluding the immediately succeeding Business    
Day.    
	      
	  	On  the first day of each Daily Interest Period, the    
Remarketing Agent shall determine the     
	  Daily Rate for such Daily Interest Period.  The determination of the    
Daily Rate by the Remarketing     
	  Agent shall be conclusive and binding.    
	      
	  	The Daily Rate for each Daily Interest Period determined by    
the Remarketing Agent shall be     
	  the lowest rate of interest which will, in the sole judgment of the    
Remarketing Agent, having due     
	  regard for prevailing financial market conditions, permit the Bonds    
to be remarketed at a price of par,     
	  plus accrued interest, on the first day of the applicable Daily    
Interest Period; provided that in no case     
	  shall the Daily Rate be more than the Maximum Rate.  In the event    
no Daily Rate is determined by     
	  the Remarketing Agent for a Daily Interest Period, then the Bonds    
shall thereupon bear interest at     
	  the last Daily Rate previously determined pursuant to the Indenture.    
	      
	  III. 	CP Rate Provisions    
	      
	  	From and after each CP Rate Conversion Date or a CP Rate    
Reset Date, as appropriate, to     
	  the earlier of their redemption, the following Conversion Date, or    
the following CP Rate Reset Date,     
	  the interest rate of this Bond shall be a CP Rate, determined as    
provided below and in the Indenture.      
	  When the Bonds are in the CP Rate Mode, in the case of each CP    
Rate Period, on the first day     
	  thereof, the Remarketing Agent shall determine (i) the duration of    
the CP Rate Period and (ii) the     
	  CP Rate which shall apply during such CP Rate Period.  The    
duration of the CP Rate Period so     
	  determined shall be that which, in the sole judgment of the    
Remarketing Agent will provide the     
	  lowest overall interest cost with respect to the Bonds, with due    
regard to prevailing financial market     
	  conditions, foreseeable changes in such conditions, the anticipated    
duration of the period the Bonds     
	  may remain in the CP Rate Mode, and such other factors which the    
Remarketing Agent, in its sole     
	  judgment, shall deem relevant and economically advantageous to    
consider.  Upon determination of     
	  the duration of the CP Rate Period, the Remarketing Agent shall    
determine the CP Rate which shall     
	  be in effect during such CP Rate Period, which shall be the lowest    
rate of interest which, in the sole     
	  judgment of the Remarketing Agent, having due regard to    
prevailing financial market conditions, will     
	  permit the Bonds to be sold at par, plus accrued interest, on the first    
day of such CP Rate Period.      
	  Notwithstanding the foregoing, the CP Rate so determined shall not    
be more than the Maximum     
	  Rate.  Unless and until the Company elects to effect a conversion of    
the Bonds from the CP Rate     
	  Mode to another Mode, the Remarketing Agent shall continually    
redetermine the duration of, and     
	  the CP Rate to be effective during each new CP Rate Period, which    
will commence, without further     
	  action on the part of the Company on each CP Rate Reset Date.  If    
on any CP Rate Reset Date the     
	  Remarketing Agent shall fail to determine either the duration of, or    
the CP Rate to be effective     
	  during the CP Rate Period which commences on such date, then,    
without further action on the part     
	  of the Company, the Bonds shall thereupon bear interest at the    
Weekly Rate determined pursuant     
	  to the Indenture.  Each determination by the Remarketing Agent    
shall be conclusive and binding.      
	  While the Bonds are in the CP Rate Mode, interest on this Bond    
will be payable on the first Business     
	  Day which follows each CP Rate Period, and shall be computed on    
the basis of a 365- or 366-day     
	  year, and the actual number of days elapsed.    
	      
	  IV.	 Adjustable Rate Provisions    
	      
	  	From and after each Adjustable Rate Conversion Date or    
Adjustable Rate Reset Date, the     
	  interest rate on this Bond shall be an Adjustable Rate, determined    
as provided below and in the     
	  Indenture.  When the Bonds are in the Adjustable Rate Mode, the    
Bonds will remain in such Mode     
	  for as long as the Company continues to deliver timely conversion    
notices specifying the duration of     
	  the next Adjustable Rate Period.  The Remarketing Agent, on or    
prior to the commencement of each     
	  Adjustable Rate Period, shall determine the Adjustable Rate to be    
borne by the Bonds during such     
	  Adjustable Rate Period, which will be the lowest rate which, in its    
sole judgment having due regard     
	  for prevailing financial market conditions, will permit the Bonds to    
be sold at par on the first day of     
	  such Adjustable Rate Period.  Notwithstanding the foregoing, the    
Adjustable Rate shall not be more     
	  than the Maximum Rate.  In the event no Adjustable Rate is    
determined by the Remarketing Agent     
	  for an Adjustable Rate Period, then the Bonds shall bear interest as    
provided in the Indenture.    
	      
	  	During each Adjustable Rate Period, interest on this Bond    
shall be paid on each Adjustable     
	  Rate Interest Payment Date and shall be computed on the basis of a    
360-day year consisting of twelve     
	  30-day months.    
	      
	  V.	Conversion Provisions    
	      
	  	The interest rate Mode of this Bond shall be converted from    
one Mode to another Mode, or     
	  from an Adjustable Rate Period of one duration to an Adjustable    
Rate Period of the same or a     
	  different duration within the Adjustable Rate Mode, if the Company    
shall give notice as provided in     
	  the Indenture of its election to effect such conversion, specifying in    
such notice the date on which     
	  the Conversion Date will occur (which date shall be at least 25 days    
after such notice is given) and,     
	  if the conversion is to an Adjustable Rate Period, specifying the    
Interest Payment Date which shall     
	  be the day following the last day of such Adjustable Rate Period    
(which Adjustable Rate Period shall     
	  be of a duration of at least six months).  The Bonds shall be subject    
to mandatory tender and     
	  purchase on the Conversion Date.  In the event any condition    
precedent to the conversion of the     
	  interest rate Mode of this Bond from one Mode to another Mode, or    
from an Adjustable Rate     
	  Period of one duration to an Adjustable Rate Period of the same or    
a different duration, is not     
	  satisfied, this Bond shall nonetheless be subject to mandatory    
tender on the Conversion Date and the     
	  Bonds shall commence bearing interest on the Conversion Date as    
provided in the Indenture.    
	      
	      
   
   
	  VI.	 Mandatory Tender    
	      
	  	All Bonds are subject to mandatory tender in whole by the    
Owners to the Tender Agent at its     
	  Principal Office on each date described below:    
	      
	  	(a)	On each Conversion Date;    
	      
	  	(b)	On each CP Rate Reset Date;    
	      
	  	(c)	On the second Business Day prior to the expiration    
or termination of the Letter of     
	  Credit (except as provided in the Indenture), if the Trustee has not    
received evidence satisfactory to     
	  it as required by the Indenture by the 25th day preceding the    
scheduled expiration or termination     
	  date of the Letter of Credit of either an extension of the then    
existing Letter of Credit or the     
	  issuance of an Alternate Credit Facility meeting the requirements    
set forth therefor in the     
	  Agreement, including the Maintenance of Rating requirement (as    
defined therein);     
	      
	  	(d)	On the date of substitution of an Alternate Credit    
Facility for the then existing Letter     
	  of Credit if the Trustee has not received evidence of a Maintenance    
of Rating with respect thereto     
	  by the 25th day preceding such substitution date;     
	      
	  	(e)	On each optional redemption date pursuant to the    
Indenture for which the Company     
	  has elected to purchase Bonds in lieu of optional redemption    
pursuant to the Indenture; and    
	      
	  	(f)	On the date on which the Guaranty is released as    
provided in the Indenture.    
	      
	  	The purchase price of Bonds subject to mandatory tender    
shall be 100% of the principal     
	  amount thereof (except in the case of a mandatory tender described    
in paragraph (c), (d), (e), or (f)     
	  above, during, but prior to the expiration date of, an Adjustable    
Rate Period, in which case the     
	  purchase price shall include a premium equal to the then applicable    
optional redemption premium,     
	  if any, on the Bonds, as set forth in the Indenture), plus accrued    
interest, if any, to the mandatory     
	  tender date.  Not later than 20 days prior to any mandatory tender    
date, the Trustee shall mail notice     
	  to all Owners of Bonds subject to mandatory tender on such date    
stating that (1) due to the     
	  occurrence of one of the events described above (which event shall    
be specified), such Owner"s     
	  Bonds will be subject to mandatory tender to the Tender Agent at    
its Principal Office on the     
	  mandatory tender date at the purchase price described above, and    
(2) interest with respect to Bonds     
	  which are not tendered on the mandatory tender date will cease to    
accrue provided Available Moneys     
	  for such purchase are on deposit with the Tender Agent on the    
mandatory tender date.  Notice of     
	  mandatory tenders described in paragraphs (a) and (e) above shall    
be given as part of the notice of     
	  conversion or optional redemption referenced above.  No failure on    
the part of the Tender Agent     
	  to give such notice shall affect the requirement that Bonds be    
tendered on the mandatory tender     
	  date.    
	      
	  	Any Bond subject to mandatory tender which is not    
tendered on or before the mandatory     
	  tender date shall, if Available Moneys sufficient and available for    
the purchase of such Bonds have     
	  been deposited with the Tender Agent on the mandatory tender    
date, be deemed to have been     
	  tendered for purchase on the mandatory tender date, and from and    
after such date, interest will no     
	  longer accrue on such Bonds.  Owners of such Bonds shall have no    
rights or benefits under the     
	  Indenture with respect to such Bonds other than to receive the    
purchase price for such Bonds upon     
	  surrender of such Bonds to the Tender Agent.    
	       
	  VII.	 Redemption of Bonds    
	      
	  	The Bonds shall be subject to optional redemption only as    
follows:    
	      
	  	a.	Weekly Rate Mode, CP Rate Mode, or Daily Rate    
Mode.  While the Bonds are in the     
	  Weekly Rate Mode or the Daily Rate Mode, they are subject to    
optional redemption, in whole or     
	  in part on any Business Day in Authorized Denominations, and    
while the Bonds are in the CP Rate     
	  Mode, they are subject to optional redemption in whole or in part in    
Authorized Denominations on     
	  any Interest Payment Date, at the direction of the Company, at a    
redemption price equal to 100%     
	  of the principal amount of the Bond to be redeemed, plus accrued    
interest thereon to the redemption     
	  date.    
	      
	  	b.	Adjustable Rate Mode.     While the Bonds are in    
the Adjustable Rate Mode, they are     
	  subject to optional redemption in whole or in part on any date, at    
the direction of the Company, only     
	  on the dates and at the applicable redemption prices set forth in the    
Indenture.    
	      
	  	While the Bonds are in the Adjustable Rate Mode or the CP    
Rate Mode, the Bonds are     
	  subject to extraordinary optional redemption in whole on any date    
at a redemption price equal to the     
	  principal amount of Bonds plus accrued interest to the redemption    
date, without premium, upon the     
	  occurrence of certain events specified in the Indenture.    
	      
	  	The Bonds in any Mode are subject to mandatory    
redemption in whole on the next date for     
	  which timely notice of redemption can be given by the Trustee after    
the occurrence of a     
	  Determination of Taxability at a redemption price equal to the    
aggregate principal amount of the     
	  Bonds plus accrued interest thereon to the redemption date, without    
premium.    
	      
	  	At least 30 days prior to any redemption of Bonds, the    
Trustee shall cause notice of the call     
	  for redemption to be sent by first class mail, postage prepaid, to the    
Owner of each Bond to be     
	  redeemed at the address of such Owner shown on the registration    
books maintained by the Trustee.      
	  Neither the failure to give any such notice nor any defect in any    
notice so mailed shall affect the     
	  sufficiency or the validity of any proceedings for the redemption of    
the Bonds.    
	      
	  	If Available Moneys are deposited in the Bond Fund on the    
date Bonds are to be redeemed,     
	  Bonds or portions thereof redeemed shall no longer be secured by    
this Indenture and shall not be     
	  deemed to be outstanding under the provisions of this Indenture.     
Interest shall not continue to     
	  accrue on the Bonds after the date fixed for redemption, so long as    
Available Moneys are on deposit     
	  to pay all principal of, premium, if any, and interest accrued on the    
Bonds on such date.  However,     
	  if Available Moneys shall not be on deposit on the redemption date,    
such Bonds or portions thereof     
	  shall continue to bear interest until paid at the same rate as they    
would have borne had they not been     
	  called for redemption.    
	      
	  	Any partial redemption of Bonds shall be made only in    
integral multiples of $100,000.  If fewer     
	  than all of the Bonds shall be called for redemption, the portion of    
Bonds to be redeemed shall be     
	  selected by the Trustee as provided in the Indenture.    
	      
	  VIII.	General Provisions    
	      
	  	Except as provided in the Indenture, the Ownership of this    
Bond may be transferred (in     
	  Authorized Denominations) only upon presentation and surrender    
of this Bond at the corporate trust     
	  office of the Trustee, together with an assignment duly executed by    
the Registered Owner hereof or     
	  his duly authorized attorney-in-fact in such form as shall be    
satisfactory to the Trustee.    
	      
	  	Provisions may be made for the payment of amounts    
represented by the Bonds as provided in     
	  the Indenture, in which event all liability of the Issuer to the    
Owners of the applicable Bonds for the     
	  payment of such Bonds shall forthwith cease, terminate, and be    
completely discharged, and thereupon     
	  it shall be the duty of the Trustee to hold such funds (but only for    
the period specified and as     
	  provided in the Indenture), without liability for interest thereon, for    
the benefit of the Owners of     
	  such Bonds, who shall thereafter be restricted exclusively to such    
funds for any claims of whatever     
	  nature under the Indenture or on, or with respect to, said Bonds.    
	      
	  	It is hereby certified and covenanted that this Bond has been    
duly and validly authorized,     
	  issued, and delivered; that all acts, conditions, and things required    
or proper to be performed, exist     
	  and be done precedent to or in the authorization, issuance, and    
delivery of this Bond have been     
	  performed, exist, and have been done in accordance with law.    
	      
	  	The Bonds are secured by the Indenture, whereunder the    
Trustee undertakes to enforce the     
	  rights of the Owners of the Bonds and to perform other duties to the    
extent and under the conditions     
	  stated in the Indenture.  In case an Event of Default shall occur, the    
principal of and interest on the     
	  Bonds then outstanding may, and, under certain circumstances,    
shall, be declared to be due and     
	  payable immediately upon the conditions and in the manner    
provided in the Indenture.  Under the     
	  circumstances and conditions provided in the Indenture, the    
Trustee may, or shall, waive any Event     
	  of Default under the Indenture and its consequences.    
	      
	  	The Issuer has reserved the right to amend the Indenture,    
with the consent of the Bank, as     
	  provided therein.  Under some (but not all) circumstances,    
amendments thereto must also be     
	  approved by the Owners of either at least a majority or 100% in    
aggregate principal amount of the     
	  outstanding Bonds.    
	      
	      
   
   
	  	In Witness Whereof, the Issuer has caused this Bond to be    
executed in its name by the     
	  manual or facsimile signature of its President or Vice President and    
attested with the manual or     
	  facsimile signature of the Secretary of Assistant Secretary all as of    
the date first above written.
