	  Article III

  	Section 3.1.  Construction of Project.  The Company hereby   
agrees to acquire and construct the Project in accordance with this Article
III, substantially in accordance with the plans and specifications therefor  
prepared by it including any and all supplements, amendments, and additions    
(or deletions) thereto (or therefrom); provided, however, that such   
other facilities and property contemplated by such supplements, amendments,  
additions, or deletions to the plans and specifications shall not materially  
impair the effective use or character of the Project as contemplated    
by this Agreement or disqualify the Project as a project within the   
meaning of the Act, or result in  the interest on any Bonds becoming  
includable in the gross income of the owners of the Bonds for    
federal income tax purposes.   
	     
  	In the event that Exhibit A hereto is to be amended or   
supplemented in accordance with the provisions of Section 9.01 of the  
Indenture, the Issuer will enter into, and will instruct the Trustee    
to consent to, an amendment of or supplement to Exhibit A hereto   
upon receipt of:   
	     
	      (i)	a copy of the proposed form of amendment or   
supplement to Exhibit A hereto; and   
	     
      	(ii)	the written approving opinion of Bond Counsel to   
the effect that such amendment or supplement will not have the effect of   
disqualifying the Project as a project within the meaning of the Act or result  
in the interest on the Bonds becoming includable in the gross income of the  
owners of the Bonds for federal income tax purposes.   
	      
  	Section 3.2.  Operation of Project.  The Company will not   
make any material change in its use of the Project from that described in  
Exhibit A unless the Trustee and the Issuer receive an opinion of Bond  
Counsel to the effect that such change will not impair the exclusion of
interest on the Bonds from the gross income of owners of the Bonds for federal  
income tax purposes.   
	     
	So long as the Company operates the Project, it will operate   
it as a "project" as contemplated by the Act and will operate the Project in  
such a manner such that it will not impair the exclusion of interest on the  
Bonds from gross income of the owners of the Bonds for federal income tax    
purposes. 	     
 	Upon a sale of all or any portion of the Company"s interest   
in the Project, the Company will obtain the agreement of the purchaser of the  
Project or interest therein to comply with the provisions of this Section 3.2,  
regardless of whether such purchaser assumes the obligations of the Company    
under this Agreement generally.   
	     
  	Section 3.3.  Establishment of Completion Date; Obligation   
of Company to Complete.  The Completion Date shall be evidenced to the  
Trustee by a certificate signed by the Authorized Company Representative  
stating the Completion Date and the Cost of the Project and stating that    
(i) construction of the Project has been completed substantially in   
accordance with the plans, specifications, and work orders therefor and all  
labor, services, materials, and supplies used in such construction have been  
paid for (other than costs and expenses for which payment has been    
withheld), (ii) all other facilities necessary in connection with the   
Project have been constructed, acquired, and installed in accordance with the  
plans, specifications, and work orders therefor and all    
costs and expenses incurred in connection therewith (other than   
costs and expenses for which payment has been withheld) have been paid,  
and (iii) at least 95% of the costs previously disbursed    
and to be disbursed from the Project Account (including moneys to   
be disbursed in accordance with the next succeeding paragraph of this Section  
3.3) are Qualified Costs of Construction, and all of such    
costs are costs permitted by the Act.  The Company may withhold   
payment and direct the Trustee to retain in the Project Account an amount  
sufficient to pay any Cost of the Project which has been incurred; such  
retained moneys shall be disbursed after the Completion Date in the manner  
provided  in Section 4.2 thereof.  If the Company withholds the payment of   
any such cost or expense of the Project the certificate shall state the amount
of such withholding and the reason therefor.  Notwithstanding the foregoing,  
such certificate may state that it is given without prejudice to any    
rights against third parties which exist at the date of such certificate   
or which may subsequently come into being.  It shall be the duty of the  
Company to cause such certificate to be furnished to the    
Trustee within 60 days after the Project shall have been completed.   
	     
	  	Moneys (including investment proceeds) remaining in the   
Project Account on the Completion Date may be used, at the direction of the  
Authorized Company Representative, to the extent indicated, for one or more  
of the following purposes:   
	     
      	(1)	for the payment, in accordance with the provisions   
of this Agreement, of any Cost of the Project not theretofore paid,
as specified in the above-mentioned completion certificate; or      
 
      	(2)	for transfer to the Bond Fund, but only if, and to   
the extent that, the Trustee has been furnished with an opinion of Bond  
Counsel to the effect that such transfer is lawful under the Act and does not  
adversely affect the exclusion from federal gross income of interest    
on any of the Bonds.   
	      
  	Any moneys (including investment proceeds) remaining in   
the Project Account on the Completion Date and not set aside for the payment  
of Costs of the Project as specified in (1) above or transferred to the Bond  
Fund pursuant to (2) above shall on such date be deposited by the Trustee in a  
separate escrow account and used to pay all or part of the redemption price of  
Bonds at the earliest redemption date or dates on which Bonds may be   
redeemed without the payment of a premium or, at the option of the  
Company, at an earlier redemption date or dates; provided that,    
until so used such moneys may also be used, at the direction of the   
Authorized Company Representative, for one or more of the following  
purposes: 	     
	  (a)	to pay all or part of the price of purchasing Bonds   
on tender, in the open market or at private sale, at a purchase price not in  
excess of 100% of the principal amount of such Bonds plus accrued interest to  
the date of such purchase for the purpose of cancellation;   
	     
      	(b)	for the payment of qualifying costs of any   
additional improvements to be installed or constructed in connection with the  
Project; provided that such use of funds is permitted under the Act; or   
	     
      	(c)	for any other purpose permitted by the Act; provided, that  
the earnings on the investment of the moneys on deposit in such escrow  
account shall be transferred on each interest payment date on the Bonds to the 
Bond Fund and shall be used to  pay interest on the Bonds coming due on  
each interest payment date on the Bonds (or to reimburse the Bank for draws  
under the Letter of Credit to pay interest on the Bonds), but no moneys on    
deposit in such escrow account may be used for any of the purposes   
specified in this paragraph (including the redemption of Bonds) unless and  
until the Trustee has been furnished with an opinion of Bond Counsel to the  
effect that such use is lawful under the Act and does not adversely affect the  
exclusion from gross income for federal income tax purposes of the   
interest on the Bonds; and provided further that, until used for one or more of 
the foregoing purposes, moneys on deposit in such escrow account may be  
invested in investments authorized by Section 4.3 of this Agreement, but    
may not be invested to produce a yield on such moneys (computed   
from the Completion Date and taking into account any investment of uch  
moneys during the period from the Completion Date until    
such moneys were deposited in such escrow account) greater than   
the yield on the Bonds from which such proceeds were derived, all as such  
terms are used in and determined in accordance with section    
148 of the Code and regulations promulgated thereunder.   
	     
  	In the event the moneys in the Project Account available for   
payment of the Costs of the Project should not be sufficient to pay the costs  
therefor, in full, the Company agrees to pay directly    
or to deposit in the Project Account moneys sufficient to pay, the   
costs of completing the Project as may be in excess of the moneys available  
therefor in the Project Account.  The Issuer does not make any warranty,  
either express or implied, that the moneys which will be paid into the Project  
Account and which, under the provisions of this Agreement, will be   
available for payment of the Costs of the Project, will be sufficient to pay
all he costs which will be incurred in that connection.  The Company    
agrees that if after exhaustion of the moneys in the Project Account   
the Company should pay, or deposit moneys in the Project Account for the  
payment of any portion of the said costs of the Project    
pursuant to the provisions of this Section it shall not be entitled to   
any reimbursement therefor from  the Issuer or from the Trustee or from the  
owners of any of the bonds, nor shall it be entitled to any    
diminution of the amounts payable under this Agreement.

Indenture and the issuance by the Issuer of the Bonds.

Section by the Company are assigned by the Issuer to the Trustee pursuant to  
the Indenture for the benefit of the Bondholders.  The Company consents to  
such assignment.  Accordingly, the Company will pay directly to the Trustee

fees, of the Trustee for any extraordinary services rendered by it under the

in accordance with the terms of the Remarketing Agreement.   
	     
  	The Company agrees to pay all Project costs not paid or   
reimbursed with Bond proceeds.  The Company has not and will not maintain  
that it is entitled to an exemption from State sales taxes on personal property
acquired in conjunction with the Project. 	     
  	Section 5.3.  Prepayments.  The Company may prepay to   
the Trustee all or any part of the amounts payable under Section 5.1(a) at any  
time, provided that the Bonds shall be subject to redemption solely as  
provided in the Indenture and the Bonds.  A prepayment shall not relieve the    
Company of its obligations under this Agreement until all the   
Bonds have been paid or provision for the payment of all the Bonds has been  
made in accordance with the Indenture.  In the event of a mandatory  
redemption of the Bonds, the Company will prepay all amounts necessary for  
such  redemption.

payments provided for in Section 5.1 hereof, (b) will perform all its other  
agreements in this Agreement and (c) will not terminate this    
Agreement for any cause including any acts or circumstances that   
may constitute failure of consideration, destruction of or damage to the

in the laws of the United States or of the State or any political   
subdivision of either, or any failure of the Issuer to perform any of its

obligation arising from or connected with this Agreement.   
	     
	  	Section 5.5.  Letter of Credit.  The Company shall provide   
for the delivery of the initial Letter of Credit to the Trustee simultaneously

replacement for the then current Letter of Credit but only in accordance with   
Section 5.03 of the Indenture.     
	     
	  Section 5.6.  Purchase of Bonds Prohibited.  So long as a   
Letter of Credit is in effect, the Company shall not, directly or indirectly,  
purchase any Bonds with any funds that do not constitute Available Moneys,  
except as required by Section 5.1(b) of this Agreement.   
	     
  	Section 5.7.  Mode Conversions.  The Company has the   
option to cause the interest rate on the Bonds to be converted from one Mode

exercised by the Company as provided in the Indenture.

consolidate with or merge into another legal entity or permit one or more  
other legal entities (other than one or more subsidiaries of the Company) to  
consolidate with or merge into it, or sell or otherwise transfer to another
legal entity all or substantially all its assets as an entirety and dissolve,   
unless (a) in the case of any merger or consolidation, the Company is the  
surviving corporation, or (b)(i) the surviving, resulting, or    
transferee legal entity is organized and existing under the laws of   
the United States, a state thereof or the District of Columbia, and (if not the
Company) assumes in writing all the obligations of the    
 
 Company under this Agreement, the Remarketing Agreement, and   
the Tax Agreement and (ii) no event which constitutes, or which with the  
giving of notice or the lapse of time or both would constitute an Event of  
Default shall have occurred and be continuing immediately after such merger,    
consolidation, or transfer.   
	     
  	Section 6.2.  Qualification in State.  Subject to the   
provisions of Section 6.1 hereof, the Company agrees that throughout the  
term of this Agreement, it will remain qualified to do business in the State.

subsidiaries, if any, at the close of each fiscal year and the results of  
operations of the Company and its consolidated subsidiaries, if any, for each  
fiscal year, accompanied by the opinion of said accountants.  The   
Trustee will hold such reports solely for the purpose of making them available  
at its principal corporate trust office for examination by the Bondholders, and 
is not required to notify the Bondholders of the contents of any such report.   
	     
  	Section 6.4.  Arbitrage.  The Company covenants with the   
Issuer and for and on behalf of the purchasers and owners of the Bonds from  
time to time outstanding that so long as any of the Bonds remain outstanding,  
moneys on deposit in any fund in connection with the Bonds, whether or not    
such moneys were derived from the proceeds of the sale of the   
Bonds or from any other sources, will not be used in a manner which will  
cause the Bonds to be "arbitrage bonds" within the meaning of    
section 148 of the Code, and any lawful regulations promulgated   
thereunder, as the same exist on this date, or may from time to time hereafter  
be amended, supplemented, or revised.  The Company also covenants for the  
benefit of the Bondholders to comply with all of the provisions of the Tax    
Agreement and the Project Certificate.  The Company reserves the   
right, however, to make any investment of such moneys permitted by State  
law, if, when and to the extent that said section 148 or regulations  
promulgated thereunder shall be repealed or relaxed or shall be held void by  
final  judgment of a court of competent jurisdiction, but only if any   
investment made by virtue of such repeal, relaxation, or decision would not,  
in the written opinion of Bond Counsel, result in making    
the interest on the Bonds includible in the federal gross income of   
the owners of the Bonds.   
	     
  	Section 6.5.  Company"s Obligation with Respect to   
Exclusion of Interest Paid on the Bonds.  Notwithstanding any other  
provision hereof, the Company covenants and agrees that it will not take    
or authorize or permit, to the extent such action is within the   
control of the Company, any action to be taken with respect to the Project, or  
the proceeds of the Bonds (including investment earnings    
thereon), or any other proceeds derived directly or indirectly in   
connection with the Project, which will result in the loss of the exclusion of  
interest on the Bonds from the federal gross income of the    
owners of the Bonds under section 103 of the Code (except for any   
Bond during any period while any such Bond is held by a person referred to  
in section 147(a) of the Code; and the Company also will not omit to take any  
action in its power which, if omitted, would cause the above result.  Toward    
that end, the Company covenants that it will comply with all   
provisions of the Tax Agreement and the Project Certificate.  This provision  
shall control in case of conflict or ambiguity with any other provision of this 
Agreement. 	     
	  Section 6.6.  Payment of Taxes.  The Company will pay and   
discharge promptly all lawful taxes, assessments, and other governmental  
charges or levies imposed upon the Project, or upon any part    
thereof, as well as all claims of any kind (including claims for   
labor, materials, and supplies) which, if unpaid, might by law become a lien  
or charge upon the Project; provided that the Company shall    
not be required to pay any such tax, assessment, charge, levy, or   
claim (i) if the amount, applicability, or validity thereof shall currently be  
contested in good faith by appropriate proceedings promptly    
initiated and diligently conducted; (ii) if the Company shall have   
set aside on its books reserves (segregated to the extent required by generally 
accepted accounting principles) with respect thereto    
deemed adequate by the Company; and (iii) if failure to make such   
payment will not impair the use of the Project by the Company.

or cause to be maintained, all necessary insurance with respect to the Project

obligated to pay the Bonds except from revenues provided by the Company or  
from other sources specified in the Indenture.  The issuance of the Bonds will  
not directly or indirectly or contingently obligate the Issuer, the Unit, or    
the State to levy or pledge any form of taxation whatever or to make   
any appropriation for their payment.  Neither the Issuer or the Unit nor any  
member or officer of the Issuer or the Unit nor any person executing the

private, or municipal, arising or resulting from, or in any way connected with  
(i) the financing, installation, operation, use, or maintenance of the Project, 
(ii) any act, including negligent acts, failure to act, or intentional    
misrepresentation by any person, firm, corporation, or   
governmental authority, including the Issuer and the Unit (except that neither  
the Issuer nor the Unit shall be indemnified for its willful    
misconduct, bad faith, or fraud), in connection with the issuance,   
sale, or delivery of the Bonds,  (iii) any act, failure to act, or  
misrepresentation by the Issuer or the Unit in connection with, or in    
the performance of any obligation related to the issuance, sale, and   
delivery of the Bonds or under this Agreement or the Indenture, or any other  
agreement executed by or on behalf of the Issuer or the Unit, including all  
liabilities, costs, and expenses, including attorneys' fees, incurred in any  
action  or proceeding brought by reason of any such claim.  In the event   
that any action or proceeding is brought against the Issuer by reason of any  
such claim, such action or proceeding shall be defended against by counsel as  
the Issuer or the Unit shall determine, and the Company shall indemnify the    
Issuer and the Unit for costs of such counsel.  The Company upon   
notice from the Issuer shall defend such an action or proceeding on behalf of  
the Issuer or the Unit.  The Company shall also indemnify the Issuer and the  
Unit from and against all costs and expenses, including attorneys' fees,    
lawfully incurred in enforcing any obligation of the Company under   
this Agreement.   
	     
  	(b)	The Company shall indemnify the Trustee, the   
Tender Agent, any person who "controls" the Remarketing Agent, the Bank,  
the Tender Agent, or the Trustee within the meaning of Section 15 of the  
Securities Act of 1933, as amended, and any member, officer, director,  
official,  and employee of the Remarketing Agent, the Bank, the Tender   
Agent, or the Trustee (collectively called the "Indemnified Parties") from and  
against, any and all claims, damages, demands, expenses, liabilities, and  
losses of every kind, character, and nature asserted by or on behalf of any  
person arising out of, resulting from, or in any way connected with (except   
for the Indemnified Party's own ct of negligence or malfeasance or  
misrepresentation) (i) the Bonds or the execution of any    
documents or the performance of any duties relating thereto, and   
(ii) the condition, use, possession, conduct, management, planning, design,  
acquisition, construction, installation, renovation, or sale of    
the Project or any part thereof.  The Company also covenants and   
agrees, at its expense, to pay, and to indemnify and hold the Indemnified  
Parties harmless of, from and against, all costs, attorneys' fees,    
expenses, and liabilities incurred in any action or proceeding   
brought by reason of any such claim or demand (except for the Indemnified  
Party's own act of negligence, malfeasance, or misrepresentation).  In the  
event that any action or proceeding is brought against the Indemnified    
Parties by reason of any such claim or demand, the Indemnified   
Parties shall immediately notify the Company, which shall defend any action  
or proceeding on behalf of the Indemnified Parties, including    
the employment of counsel, the payment of all expenses and the   
right to negotiate and consent to settlement.  Any one or more of the  
Indemnified Parties shall have the right to employ separate    
counsel in any such action and to participate in the defense thereof,   
but the fees and expenses of such counsel shall be at the expense of such  
Indemnified Parties unless the employment of such    
counsel has been specifically authorized by the Company or unless   
the Indemnified Parties shall reasonably determine that a conflict of interest  
exists as between the Indemnified Parties and the Company, in either of  
which instances the fees and expenses of such counsel shall be paid by the    
Company.  If such separate counsel is employed, the Company may   
join in any such suit for the protection of its own interests.  The Company  
shall not be liable for any settlement of any such action effected without its  
consent, but if settled with the consent of the Company or if there be a final  
judgment for the plaintiff in any such action, the Company agrees   
to indemnify and hold harmless the Indemnified Parties.

either the Issuer or the Trustee, but no assignment will,    
except as provided in the following paragraph, relieve the Company   
from primary liability for any  obligations under this Agreement and no such  
assignment will be made unless the Company causes    
there to be delivered to the Trustee an opinion of Bond Counsel to   
the effect that such assignment will not cause interest on the Bonds to be

purposes.   
	     
  	Notwithstanding the provisions of the preceding paragraph,   
this Agreement may be assigned by the Company as provided in the

Default.   
	     
  	Section 9.2.  Delay Not Waiver; Remedies.  A delay or   
omission by the Issuer or the Trustee  in exercising any right or remedy  
accruing upon an Event of Default shall not impair the right or

are cumulative. 	     
 
  	Section 9.3.  Attorneys Fees and Expenses.  If the Company
