         WHEREAS, the Bonds will be further secured by the unconditional
guaranty of payment of principal of and interest on the Bonds by Central CPVC
Corporation, an Alabama corporation; and

         WHEREAS, the Bonds are the limited obligations of the Lessor payable

Trustee will not have a mortgage on or security interest in the Project. The

         WHEREAS, the Bonds never shall constitute the debt or indebtedness of
the City of Huntsville (the "City") or the State of Alabama (the "State"),
within the meaning of any provision or limitation of the constitution or
statutes of Alabama, and shall not constitute or give rise to a pecuniary
liability of the Lessor, its members or the City or the State or a charge

         Section 2.1 Representations and Warranties by the Lessor. The Lessor
represents and warrants that:

         (a) By proper corporate action, the Lessor has duly authorized the
execution and delivery of this Agreement, the Indenture, the Bonds and all other
instruments and documents previously or contemporaneously executed and delivered
by the Lessor in connection with the Bonds. Subject to Section 9.3 hereof, the
Lessor agrees that it will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence.

         (b) Notwithstanding anything herein to the contrary, any obligation
that the Lessor may incur pursuant to the terms of this Agreement for the
payment of money shall not be a general debt on its part but shall be payable
solely from proceeds derived from this Agreement, draws on the Letter of Credit,
the sale of the Bonds and the insurance and condemnation awards as herein
provided.

         Section 2.2 Representations and Warranties by Lessee. The Lessee
represents and warrants that:

          (a) The Lessee is a corporation duly organized, validly existing and
in good standing under the laws of the State of Alabama. Lessee has all
requisite power and authority, corporate and otherwise, to conduct its business
and to own its properties and is duly qualified as a foreign corporation in good
standing in all jurisdictions in which its failure so to qualify could have a
Material Adverse Effect on its financial condition or business.

         (b) The Lessee has, by all necessary action, duly authorized the
execution, delivery and performance of this Agreement, and when duly executed
and delivered by the Lessor, this Agreement will constitute a legal, valid and
binding obligation of the Lessee.

         (c) The Lessee will comply fully at all times with the Lessee's
Arbitrage and Tax Certificate, and the Lessee will not take any action, or omit
to take any action, which, if taken or omitted, respectively, would violate the
Lessee's Arbitrage and Tax Certificate.

         Section 2.3 Continuing Disclosure The Bonds are exempt from the
continuing disclosure requirements of Section (b)(5) of Rule 15c2-12 (the
"Rule") adopted by the Securities and Exchange Commission under the Securities
Exchange Act of 1934, as amended and supplemented, so long as they bear interest
at the Floating Rate (as defined in the Indenture). If the Bonds are converted

                                       12
<PAGE>

to the Fixed Rate (as defined in the Indenture), the Bonds may become subject to
the continuing disclosure requirements of the Rule. In such event, the Lessee
agrees to enter into a continuing disclosure agreement with the Trustee, in form
satisfactory to Bond Counsel. The Lessee hereby covenants and agrees with the
Bondholders that it will comply with and carry out all of the provisions of such
continuing disclosure agreement, as amended from time to time, applicable to it.
Notwithstanding any other provision of this Agreement, failure of the Lessee to
comply with such continuing disclosure agreement shall not be considered a
default or an event of default under this Agreement and the rights and remedies
provided by this Agreement upon the occurrence of a Default shall not apply to
any such failure, but the continuing disclosure agreement may be enforced only
as provided therein.

marketable title to the Project, free from all encumbrances other than Permitted
Encumbrances and other than the encumbrances set forth in the granting clauses
of the Indenture, and the Lessor has or will promptly obtain title insurance in
form and amount acceptable to the Trustee with respect to the Leased Land. The
Net Proceeds from such insurance shall be paid to the Trustee and applied in
accordance with Section 7.2 hereof. To the extent such insurance is available to
redeem Bonds pursuant hereto, no claim shall be made and no suit brought
hereunder against the Lessee by the title insurance company or anyone else
claiming on behalf of or by, through or under it.

         Section 3.3 Quiet Enjoyment and Possession. The Lessor covenants and
agrees that as long as the Lessee shall not be in default under this Lease

Agent and the Lessor. Any Substitute Letter of Credit shall be delivered to the
Trustee on an Interest Payment Date and not later than the thirtieth (30th)
Business Day prior to the expiration of the Letter of Credit it is being issued
to replace. On or before the date of the delivery of any Substitute Letter of
Credit to the Trustee, as a condition to the acceptance of any Substitute Letter
of Credit by the Trustee, the Lessee shall furnish to the Lessor, the Trustee
and the Remarketing Agent: (i) written evidence that the issuer of such
Substitute Letter of Credit is a commercial bank or other financial institution
organized and doing business in the United States or a branch or agency of a
foreign commercial bank located and doing business in the United States and
subject to regulation by state or federal banking regulatory authorities and
that it has been assigned the same or better rating as the Letter of Credit in
effect immediately prior to the substitution of the Substitute Letter of Credit;
(ii) an opinion of nationally recognized bond counsel to the effect that the
delivery of such Substitute Letter of Credit is authorized under this Agreement
and the Indenture and the Act and complies with the terms hereof, and, that the
delivery of such Substitute Letter of Credit does not adversely affect the
exclusion from gross income of the interest on the Bonds for federal income tax
purposes; and (iii) an opinion of Counsel satisfactory to the Trustee, the
Lessor, the Lessee and the Remarketing Agent to the effect that the Substitute
Letter of Credit is a legal, valid and binding obligation of the issuer (or, in
the case of a branch or agency of a foreign commercial bank, the branch or
agency) issuing the same, enforceable in accordance with its terms, that
payments of principal of, and to the extent the Letter of Credit covers same,
any premium on the Bonds, or Purchase Price of or interest on the Bonds from the
proceeds of a drawing on the Substitute Letter of Credit will not constitute

                                       14

regulations and that it is not necessary to register the Substitute Letter of
Credit under the Securities Act of 1933, as amended, or to qualify an indenture
with respect thereto under the Trust Indenture Act of 1939, as amended. On or
before the delivery of any Substitute Letter of Credit to the Trustee, as an
additional condition to the acceptance of any Substitute Letter of Credit by the
Trustee, the Lessee shall furnish to the Lessor, the Trustee and the Remarketing
Agent written evidence from each Rating Agency that the rating on the Bonds will
not be reduced or withdrawn as a result of the acceptance of the Substitute
Letter of Credit and that the short term unsecured debt of the Bank or
Substitute Bank, as applicable, shall then have been assigned a rating by
Moody's of "P-1" or the equivalent rating assigned by S&P. In the case of a
Substitute Letter of Credit issued by a branch or agency of a foreign commercial
bank there shall also be delivered an opinion of Counsel, satisfactory to the
Trustee, the Lessor, the Lessee and the Remarketing Agent and licensed to
practice law in the jurisdiction in which the head office of such bank is
located, to the effect that the Substitute Letter of Credit is the legal, valid
and binding obligation of such bank enforceable in accordance with its terms.
The Trustee shall accept any such Substitute Letter of Credit only in accordance
with the terms, and upon the satisfaction of the conditions, contained in this
Section 4.3 and any other provisions applicable to acceptance of a Substitute
Letter of Credit under this Agreement and the Indenture.

way connected with the Project, including but not limited to the condition, use,
possession, conduct or management of, or any work done in or about, the Project,
or from the planning, design, acquisition or improvement of the Project or any
part thereof, or from the lease or sale of any part thereof. The Lessee will
also pay and discharge and will indemnify and hold harmless the Lessor from: (a)
any lien or charge upon payments by the Lessee to the Lessor hereunder, and (b)
any taxes, assessments, impositions and other charges, in respect to the
Project. The Lessee also covenants and agrees to pay and to indemnify and save

<PAGE>

the Lessor harmless of, from and against, all of the Lessor's costs, expenses
(including reasonable counsel fees) and liabilities incurred in any action or
proceeding brought by reason of any such claim or demand. If any such claim is
asserted, or any such lien or charge upon payments, or any taxes, assessments,
impositions or other charges are sought to be imposed, and either the Lessor and
the Trustee has notice or knowledge thereof the Lessor or the Trustee, as the
case may be, will give prompt notice to the Lessee, and the Lessee shall have
the sole right and duty to assume, and will assume the defense thereof on the
Lessee's behalf and on behalf of the Lessor, with full power to litigate,
compromise or settle the same in the Lessee's sole discretion; provided,
however, if the Lessor deems it necessary, the Lessor may obtain its own Counsel
in such action and the Lessee agrees to pay the reasonable fees and expenses of
such counsel.

         Notwithstanding the foregoing, nothing set forth in this Section 5.5
shall be construed to indemnify the Lessor for or release the Lessor from any
liability which it would otherwise have had arising from the willful, wrongful
or negligent actions or failures to act on the part of the Lessor, its
employees, agents or representatives acting in their capacities other than as
contemplated by this Lease Agreement.

         Section 5.6 Obligation of Lessee Unconditional. The obligation of the
Lessee to make the payments pursuant to this Lease Agreement and to perform and
observe the other agreements on the Lessee's part set forth herein shall be
absolute and unconditional, shall not be subject to any defense or any right of
set-off, counterclaim, recoupment, abatement or otherwise, arising out of any
breach by the Lessor of any obligation to the Lessee, whether hereunder or
otherwise, or out of any indebtedness or liability at any time owing to the
Lessee by the Lessor. The Lessee hereby agrees to pay to the Trustee all of said
payments payable by the Lessee pursuant to Section 5.3 of this Lease Agreement.
Until such time as the principal of and interest on the Bonds shall have been
fully paid or provisions for the payment thereof shall have been made in
accordance with the Indenture, the Lessee: (i) will not suspend or discontinue
any payments pursuant to this Lease Agreement, (ii) will perform and observe all
the Lessee's other agreements set forth in this Lease Agreement, and (iii)
except as provided in Article XI hereof, will not terminate this Lease Agreement
for any cause including, without limiting the generality of the foregoing,
failure of the Lessor to complete the Project, failure of the Lessor's title to
the Project or any part thereof, loss of title to (or the temporary use of) the
Project by virtue of the exercise by others of the power of eminent domain, any
acts or circumstances, that may constitute failure of consideration, destruction
of or damage to the Project, commercial frustration of purpose, any change in
the tax or other laws of the United States of America or of the State of
Alabama, or any political subdivision of either thereof, or any failure of the
Lessor to perform and observe any agreement, whether express or implied, or any
duty, liability or obligation arising out of or connected with this Lease
Agreement.

         Nothing set forth in this Section 5.6 shall be construed to release the
Lessor from the performance of any of the agreements on its part herein set
forth. In the event the Lessor shall fail to perform any such agreement on its
part, the Lessee may institute such action against the Lessor as the Lessee may

                                       18
<PAGE>

deem necessary to compel performance or may pursue such other remedies for
non-performance as may be available to the Lessee so long as such action shall
not violate the agreements on the part of the Lessee set forth in the preceding
paragraph. In no event, however, shall the Lessee be entitled to any diminution
of the amounts payable under Section 5.3 hereof. The Lessee may, however, at the
Lessee's own cost and expense and in the Lessee's own name or in the name of the
Lessor, prosecute or defend any action or proceeding or take any other action
involving third persons which the Lessee deems reasonably necessary in order to
insure the acquisition, construction, installation and equipping of the Project
or to secure or protect the Lessee's right of possession, occupancy and use
hereunder, and in such event, the Lessor hereby agrees to cooperate fully with
the Lessee and to take all action necessary to effect the substitution of the
Lessee for the Lessor in any such action or proceeding if the Lessee shall so
request.

         Section 5.7 Ad Valorem Taxes. The Lessee and the Lessor acknowledge
that under present law the Project is not exempt, by reason of this Lease, from
ad valorem taxes. The Project, however, is subject to an abatement of certain
non-educational taxes.

         Section 5.8 Lessee Entitled to Certain Rent Abatements if Bonds Paid
Prior to Maturity. If at any time the aggregate monies available in a bond
escrow agreement approved by the Trustee shall be sufficient to retire all of
the Bonds outstanding in accordance with the provisions of the Indenture, and to
pay all fees and charges of the Trustee and paying agents due or to become due
through the date on which the last of the Bonds is retired under circumstances
not resulting in termination of the Lease Term, and if the Lessee is not at the
time otherwise in default hereunder, the Lessee shall be entitled to use and
occupy the Project from the date on which such aggregate monies are in the hands
of the Trustee to and including the last day of December, 2013 without the
payment of the rent specified in Section 5.3 during that interval (but otherwise
on the terms and conditions thereof).

                        --------------------------------

         Section 6.1 Maintenance and Modification of Project by Lessee. The
Lessee will, at the Lessee's sole expense, during the Lease Term, keep the
Project in as reasonably safe condition as its operations shall permit and in
good repair and in good operating condition, making from time to time all
necessary repairs thereto (including external and structural repairs). The
Lessee may, also at the Lessee's expense, make from time to time any additions,
modifications or improvements to the Project that the Lessee may deem desirable
for the Lessee's business purposes and that do not adversely affect the
structural integrity of the Project or substantially reduce its value. All such
renewals, replacements, additions, modifications and improvements so made by the
Lessee shall become part of the Project. The Lessee may, also at the Lessee's
own expense, locate on the Leased Land any tangible personal property not
purchased by the Lessor with the proceeds from the sale of the Bonds which, in
the Lessee's judgment, is essential to the operation of the Project.

         The Lessee will not permit any mechanics', materialmen's or other liens
(except Permitted Encumbrances) to be established or remain against the Project
for labor or materials furnished in connection with the Project or any
additions, modifications, improvements, repairs, renewals or replacements so
made by the Lessee; provided, that if the Lessee shall first notify the Trustee
of the Lessee's intention to do so, the Lessee may in good faith contest any
mechanics', materialmen's or other lien filed or established against the
Project, and in such event, may permit the items so contested to remain
undischarged and unsatisfied during the period of such contest and any appeal
therefrom unless (i) the Lessor or the Trustee and (ii) the Bank shall notify
the Lessee that, in the opinion of Independent Counsel, by non-payment of any
such items, the security afforded pursuant to the terms of the Indenture will be
materially endangered or the Project or any part thereof will be subject to loss
or forfeiture, and in either of such events, the Lessee shall promptly pay and
cause to be satisfied and discharged all such unpaid items or secure such
payment by posting a bond, in form satisfactory to the Lessor and the Trustee,
with the Trustee. The Lessor will cooperate fully with the Lessee in any such
contest.

         Section 6.2 Taxes, Other Governmental Charges and Utility Charges. The
parties to this Lease Agreement understand and acknowledge that: (i) under
present law the income and receipts, if any, of the Lessor from the Project are
not subject to either Federal or State income taxation, and (ii) this factor
among others, has induced Lessee to enter into this Lease Agreement.
Nevertheless, the Lessee will pay during the Lease Term, as the same
respectively become due, all taxes and governmental charges of any kind
whatsoever that may at any time be lawfully assessed or levied against or with
respect to the Project or any equipment or other personal property installed or
brought by the Lessee therein or thereon (including, without limiting the
generality of the foregoing, any taxes levied upon or with respect to the income
or profits of the Lessor from the Project which, if not paid, will become a
charge on the Project prior to or on a parity with the lien of the Indenture or

                                       20

a charge on the revenues and receipts from the Project prior to or on a parity
with the charge thereon and the pledge or assignment thereof to be created and
made in the Indenture, and including any ad valorem taxes lawfully assessed
thereupon), all utility and other charges incurred in the operation,
maintenance, use, occupancy and upkeep of the Project and all assessments and
charges lawfully made by any governmental body for public improvements that may
be secured by lien on the Project; provided, that with respect to special
assessments or other governmental charges that may lawfully be paid in
installments over a period of years, the Lessee shall be obligated to pay only
such installments as are required to be paid during the Lease Term. The
foregoing provisions of this Section 6.2 shall be effective only so long as any
Bonds remain outstanding or any part of the principal of or the interest on the
Bonds remains unpaid.

         The Lessee may, at its expense and in its own name and behalf, or in
the name and behalf of the Lessor, in good faith, contest any such taxes,
assessments and other charges and, in the event of any such contest, may permit
the taxes, assessments or other charges so contested to remain unpaid during the
period of such contest and any appeal therefrom unless (i) the Lessor or the
Trustee and (ii) the Bank shall notify the Lessee that, in the opinion of
Independent Counsel, by non-payment of any such items, the security afforded
pursuant to the terms of the Indenture will be materially endangered or the
Project or any part thereof will be subject to loss or forfeiture, and in either
of such events such taxes, assessments or charges shall be paid forthwith by the
Lessee. The Lessor will cooperate fully with the Lessee in any such contest.

         In the event that the Lessee shall fail to pay any of the foregoing
items required by this Section 6.2 to be paid by the Lessee, the Lessor, the
Trustee or the Bank may, but shall be under no obligation to pay the same and
any amounts so advanced therefor by the Lessor or the Trustee shall become an
additional obligation of the Lessee to the one making the advancement, which
amounts, together with interest thereon at a per annum rate equal to one
percentage point in excess of the Base Rate from the date thereof, the Lessee
agrees to pay.

         Section 6.3 Insurance Required to be Carried. The Lessee shall carry
such insurance as may be required in the Credit Agreement or, if none is
required therein, then the Lessee shall carry the following insurance:

         (a) Insurance to the extent of the full insurable value of the Project
         against loss thereto from, or damage by vandalism, fire, and lightning,
         with uniform standard form of extended coverage endorsement at the time
         in use in the State; and

         (b) Insurance against liability for injuries to, or death of any
         person, or damage to or loss of property arising out of or in any way
         relating to the condition or operation of the Project or any portion
         thereof, in the minimum amounts of $1,000,000 for death of or personal
         injury to any one person, and $200,000 for property damage in any one
         accident.

         Section 6.4 Destruction, Damage and Eminent Domain. If the Project
Facilities shall be wholly or partially destroyed or damaged by fire or other
casualty covered by insurance, or shall be wholly or partially condemned, taken
or injured by any Person, including any Person possessing the right to exercise
the power of or a power in the nature of eminent domain or shall be transferred
to such a Person by way of a conveyance in lieu of the exercise of such a power
by such a Person, the Lessee covenants that it will take all actions and will do
all things which may be necessary to enable recovery to be made upon such
policies of insurance or on account of such taking, condemnation, conveyance,
damage or injury. The Lessee is authorized, in its own name, as trustee of an
express trust, to demand, collect, sue, settle claims, receipt and release
monies which may be due and payable under policies of insurance covering such
damage or destruction or on account of such condemnations, damage or injury. Any
moneys recovered: (i) on policies of insurance required to be maintained
hereunder; or (ii) as a result of any taking, condemnation, conveyance, damage
or injury shall be deposited with the Trustee under the Indenture and shall be
applied in accordance with the provisions of Section 7.1 hereof; provided,
however, that as long as the Letter of Credit Bank is not in default under the
terms of the Letter of Credit, the applicable provisions of the Credit Agreement
shall control the disposition of casualty insurance and condemnation award
proceeds.

         Any appraisement or adjustment of loss or damage and any settlement or
payment therefor, shall be agreed upon by the Lessee, the Bank (as long as the
Letter of Credit Bank is not in default under the Letter of Credit) and the
appropriate insurer or condemnor or Person, and shall be evidenced to the Bank
by the certificate and approvals set forth in the Indenture. The Bank may rely
conclusively upon such certificates.

         Section 6.5. Notice of Property Loss. After the occurrence of loss or
damage to, or after receipt of notice of condemnation of, the Project
Facilities, the Lessee shall within five (5) Business Days thereof notify the
Trustee and the Bank, in writing, of such damage.


         Section 6.6 Advances by Lessor or Trustee. In the event the Lessee
shall fail to maintain the full insurance coverage required by this Agreement or
shall fail to keep the Project in as reasonably safe condition as its operating
conditions will permit, or shall fail to keep the Building in good repair and
good operating condition, the Lessor or the Bank, after first notifying the
Lessee of any such failure on the Lessee's part and after giving the Lessee a
reasonable opportunity to cure such default, may, but shall be under no
obligation to, take out the required policies of insurance and pay the premiums
on the same, or make the required repairs; and all amounts so advanced therefor
by the Lessor or the Bank shall become an additional obligation of the Lessee to
the one making the advancement.

         Section 6.7 Removal of Leased Equipment. The Lessor shall not be under
any obligation to renew, repair, or replace any inadequate, obsolete, worn out,
unsuitable, undesirable or unnecessary Leased Equipment. In any instance where
the Lessee, in the Lessee's sole discretion, determines that any items of Leased

                                       22
<PAGE>

Equipment have become inadequate, obsolete, worn out, unsuitable, undesirable or
unnecessary, the Lessee may, subject to the consent of the Bank, remove such
items of Leased Equipment from the Building and the Leased Land and, on behalf
of the Lessor, sell, trade-in, exchange or otherwise dispose of them, as a whole
or in part, without any responsibility or accountability to the Lessor therefor.

         The removal from the Project of any portion of the Leased Equipment
pursuant to the provisions of this Section shall not entitle the Lessee to any
abatement or diminution of the amounts payable under Section 5.3 hereof. The
Lessee will not remove, or permit the removal of any of the Leased Equipment
from the Leased Land except in accordance with the provisions of this Section
6.7.

         Section 7.1 Disposition of Casualty Insurance and Condemnation Award
Proceeds. Subject to the provisions of Section 6.4 hereof, and, if applicable in
accordance with Section 6.4 hereof, the Credit Agreement, and as long as the
Lessee is not in default under the terms of this Agreement, the Lessee may
elect, in its discretion, whether to apply the proceeds of any casualty
insurance coverage and/or condemnation awards to: (i) the repair, reconstruction
or replacement of damaged, destroyed or injured property comprising the Project
Facilities; or (ii) the redemption of Bonds pursuant to the applicable
provisions of the Indenture. Absent timely direction from the Lessee as to the
application of any casualty insurance coverage and/or condemnation awards or if
the Lessee shall be in default under the terms of this Agreement, the proceeds
thereof shall be applied to the extraordinary redemption of the Bonds at par
plus accrued interest through the date of redemption. For purposes of the
preceding sentence, "timely direction" shall mean 30 days after the Lessee has
agreed, in connection with any damage to or condemnation of the Project
Facilities, upon the settlement or payment with respect to any appraisement or
adjustment of loss or damage, as appropriate.

         Section 7.2 Condemnation or Failure of Title. Unless the Lessee shall
exercise its option to purchase pursuant to the provisions of Section 11.2
hereof, in the event that title to, or the temporary use of the Project or any
part thereof or the leasehold estate of the Lessee in the Project created by
this Lease Agreement or any part thereof shall be taken under the exercise of
power of eminent domain by any governmental body or by any person, firm or
corporation acting under governmental authority, or in the event of a failure of
title, the Lessee shall be obligated to continue to pay the amounts specified in
Section 5.3 hereof. Subject to any contrary provisions contained in Section 6.4
hereof, and, if applicable in accordance with Section 6.4 hereof, the Credit
Agreement, the Lessor and the Lessee will cause the Net Proceeds received by
them or any of them, from any award made in such eminent domain proceedings, or
from the title insurance policy purchased pursuant to Section 3.2 hereof to be
deposited with the Trustee and to be applied by the Trustee in one or more of
the following ways as shall be directed in writing by the Lessee:

                                       23
<PAGE>


         (a) The restoration of the Building and improvements comprising part of
the Project to substantially the same condition as they exist immediately prior
to the exercise of the said power of eminent domain or failure of title.

         (b) Redemption of the Bonds and payment of accrued interest thereon to
the date of redemption.

         If the Bonds have been fully paid (or provision for payment thereof has
been made in accordance with the provisions of the Indenture) all such Net
Proceeds shall be paid to the Lessee.

         The Lessor shall cooperate fully with the Lessee in the handling and
conduct of any prospective or pending condemnation, or failure of title
proceeding with respect to the Project or any part thereof and will, to the
extent it may lawfully do so, permit the Lessee to litigate in any such
proceeding in the name and behalf of the Lessor. In no event will the Lessor
voluntarily settle, or consent to the settlement of, any prospective or pending
condemnation or title proceeding with respect to the Project or any part thereof
without the prior written consent of the Lessee.

         Section 7.3 Condemnation of Lessee Owned Property. The Lessee shall
also be entitled to the Net Proceeds of any condemnation award or portion
thereof made for damages to, or takings of its own property not included in the
Project, provided that any Net Proceeds resulting from damages to, or a taking
of all or any part of the leasehold estate of the Lessee in the Project created
by this Lease Agreement shall be paid and applied in the manner provided in
Section 7.2 hereof.

         Section 8.2 Inspection of the Project. The Lessor, the Bank, the
Trustee, and their or any of their duly authorized agents shall have the right
at all reasonable times to enter at their own risk upon the site of the Project
and examine and inspect the Project. The Lessor and its duly authorized agents
shall also have such rights of access to the Project as may be reasonably
necessary for the proper maintenance of the Project in the event of failure by
the Lessee to perform the Lessee's obligations under Section 6.1 hereof. Any
inspection of the Project by the Lessor, the Bank, the Trustee, and their or any
of their duly authorized agents, shall be for the benefit of the Lessor, the
Bank and the Trustee, respectively, and no third party shall have the right to

provision of this Agreement, the parties hereto reserve the right at any time,
and from time to time, but only with the prior written consent of the Bank, to

Leased Land with respect to which the Lessor proposes to grant an easement or
convey fee title to a railroad, public utility or public body in order that
railroad, utility services or roads may be provided for the Project, provided

or of this Lease Agreement, and the Lessee is not, to the knowledge of the
Lessor, in default under any of the provisions of this Lease Agreement, (ii)
stating an adequate legal description of that portion of the Leased Land to be

release of such property from the lien of the Indenture;

         (c) A certificate of the Lessee approving such amendment and stating
that the Lessee is not in default under any of the provisions of this Agreement;

         Section 8.6  [Reserved]

         Section 8.7 Authorized Lessor Representative. Whenever under the
provisions of this Lease Agreement the approval of the Lessor is required or the
Lessor is required to take some action, such approval shall be made or such
action shall be taken by the Authorized Lessor Representative, and the Lessee
and the Trustee shall be authorized to act on any such approval or action;
provided, however, that in any case in which the Bank's consent or approval is
required, the Trustee shall also obtain the Bank's consent or approval before so
acting.

         Section 8.8 Authorized Lessee Representative. Whenever under the
provisions of this Lease, the approval of the Lessee is required or the Lessee
is required to take some action, such approval shall be made or such action
taken by the Authorized Lessee Representative, and the Lessor and the Trustee

         Section 8.9 Additional Covenants. The Lessee shall comply with each of
the covenants on its part set forth in the Credit Agreement, and any other
similar agreement entered into in connection with the issuance of any Substitute
Letter of Credit and any and all modifications, alterations, amendments and
supplements thereto.

         Section 8.10 Additional Tax Covenants and Representations. (a) The
Lessee covenants that it will not take any action, or fail to take any action,
if any such action or failure to take action would adversely affect the
exclusion from gross income of the interest on any Bond under Section 103 of the
Code. The Lessee will not directly or indirectly use or permit the use
(including the making of any investment) of any Bond Proceeds or any other funds
of the Lessor or the Lessee, or take or omit to take any action, that would
cause the Bonds to be "arbitrage bonds" within the meaning of Section 148(a) of
the Code.

         (b) The Lessee hereby covenants that in connection with complying with
the requirement for payment of the Rebatable Arbitrage to the United States with
respect to the Bonds, all of the gross Bond Proceeds (within the meaning of
Section 148(f) of the Code), other than gross Bond Proceeds on deposit in a bona
fide debt service fund (within the meaning of Section 148(f)(4) of the Code),
were expended on or prior to the Initial Rebate Computation Date.

         (c) The Lessee acknowledges that the Lessor shall have the right at any
time and in the sole and absolute discretion of the Lessor to obtain from the
Lessee and the Trustee the information necessary to determine the amount
required to be paid to the United States pursuant to Section 148(f) of the Code.
Additionally, the Lessor may, with reasonable cause, (A) review or cause to be
reviewed any determination of the amount to be paid to the United States made by
or on behalf of the Lessee and (B) make or retain a Rebate Expert to make the
determination of the amount to be paid to the United States. The Lessee hereby
agrees to be bound by any such review or determination, absent manifest error,
to pay the costs of such review, including without limitation the reasonable
fees and expenses of counsel or a Rebate Expert retained by the Lessor, and to
pay any Rebate that might be required as the result of any such review or
determination.

         (d) Notwithstanding any provision of this subsection to the contrary,
the Lessee shall be liable, and shall indemnify and hold the Lessor and the
Trustee harmless against any liability, for payments due to the United States
pursuant to Section 148(f) of the Code. Further, the Lessee specifically agrees
that neither the Lessor nor the Trustee shall be held liable, or in any way
responsible, and the Lessee shall indemnify and hold harmless the Trustee and
Lessor against any liability, for any mistake or error in the filing of the
payment or the determination of the amount due to the United States or for any
consequences resulting from any such mistake or error. The provisions of this
paragraph (vi) shall survive termination of this Agreement.

         (e) The Lessee will aid and assist the Lessor in connection with
preparing and submitting to the Internal Revenue Service a Form 8038 (or other
applicable information reporting statement) at the time and in the form required
by the Code.

         (f) The Lessee will comply fully at all times with the Lessee's
Arbitrage and Tax Certificate, and the Lessee will not take any action, or omit
to take any action, which, if taken or omitted, respectively, would violate the
Lessee's Arbitrage and Tax Certificate.

         (g) The Project was not acquired or placed in service by the Lessee
(determined in accordance with the provisions of Section 103 of the Code and
applicable regulations thereunder) more than one (1) year prior to the date of
issuance of the Bonds.

         (h) Subsequent to fifteen (15) days prior to the date the Bonds are
sold, the Lessee or any Related Person (or group of related persons which
includes the Lessee) has not, or will not, as the case may be, guarantied,
arranged, participated in, assisted with, borrowed the proceeds of, or leased
facilities financed by obligations issued pursuant to Section 103 of the Code by
any state or local governmental unit or any constituted authority empowered to
issue obligations by or on behalf of any state or local governmental unit other
than the Lessor. During the period commencing on the date of the sale of the
Bonds and ending fifteen (15) days thereafter, there will be no obligations
issued pursuant to Section 103 which are guarantied by the Lessee or any Related
Person (or group of related persons which includes the Lessee) or which are
issued with the assistance or participation of, or by arrangement with, the
Lessee or any Related Person (or group of related persons which includes the
Lessee) without the written opinion of Bond Counsel to the effect that the
issuance of such obligation will not adversely affect their opinion as to the
exclusion of interest on the Bonds from the gross income of the Purchaser under
Section 103 of the Code. Other than the Lessee or any Related Person (or group
of related persons including the Lessee), no person has (i) guarantied,
arranged, participated in, assisted with the issuance of, or paid any portion of
the cost of the issuance of the Bonds, or (ii) provided any property or any
franchise, trademark or trade name (within the meaning of Code Section 1253)
which is to be used in connection with the Project.

                                       27

         (i) The information contained in the Lessee's Arbitrage and Tax
Certificate, setting forth the respective cost, economic life, ADR midpoint
life, if any, under Rev. Proc. 87-56, 1987-2 C.B. 674, as supplemented and
amended from time to time, and guideline life, if any, under Rev. Proc. 62-21,
1962-2 C.B. 118, as supplemented and amended from time to time, of each asset
constituting the Project financed with the Bond Proceeds is true, accurate and
complete.

         (j) The Project does not share "substantial common facilities", within
the meaning of Section 144(a)(9) of the Code, with any other facility financed
by an outstanding tax-exempt bond.

         (k) The Lessee has not taken and will not take any action and knows of
no action that any other person has taken or intends to take, which would cause
interest income on the Bonds to be includable in the gross income of the
recipients thereof under Section 103 of the Code. The Lessee will take and will
cause its officers, employees and agents to take all affirmative actions legally
within its power necessary to ensure that the interest on the Bonds does not
become includable in gross income of the recipient for federal income tax
purposes under the Code (including, without limitation, the calculation of
rebate required to preserve such exclusion).

         (l) The Bonds will not be federally guaranteed within the meaning of
Section 149(b) of the Code. For purposes of this representation, no Principal
User of the Project has entered into any leases of the Project to, or any sales
or service contracts with, any federal government agency with the result that
the Bonds are so federally guaranteed within the meaning of Section 149(b) of
the Code.

         Section 9.1 Assignment and Subleasing. Subject to the consent of the
Bank so long as the Letter of Credit Bank is not in default of its obligations
under the Letter of Credit, this Lease may be assigned or subleased as a whole
or in part, by the Lessee without the necessity of obtaining the consent of
either the Lessor or the Trustee, provided that, however, no such assignment or
further sublease shall cause the Project to no longer constitute a "project"
under the Act, have any effect on the tax exempt status of the interest on the
Bonds or shall relieve the Lessee from primary liability for any of the Lessee's
obligations hereunder, and in the event of any such assignment or sublease, the
Lessee shall continue to remain primarily liable for payment of the amounts
specified in Section 5.3 hereof and for performance and observance of the other
agreements on the Lessee's part herein provided to be performed and observed by
the Lessee to the same extent as though no assignment or sublease had been made.

Lease Agreement and the rentals hereunder to the Trustee pursuant to the
Indenture, it will not mortgage, sell, assign, transfer or convey its interest
in the Project during the term of this Agreement, except as herein provided. If
the laws of the State of Alabama at the time shall permit such action to be
taken, nothing in this Section 9.3 shall prevent the consolidation of the Lessor
with, or merger of the Lessor into, or transfer of its remaining interest in the
Project or in this Lease Agreement as an entirety to, any public corporation
whose income is not subject to taxation and which has corporate authority to
exercise the Lessor's rights granted hereunder; provided: (i) that no such
action shall be taken without the prior written consent of the Lessee, unless
such action shall be required by law, (ii) that any such action shall be
approved by the governing body of the City of Huntsville, Alabama, and (iii)
that upon any such consolidation, merger or transfer, the due and punctual
payment of the principal of, premium, if any, and interest on the Bonds
according to their tenor, and the due and actual performance and observance of
all the agreements and conditions of this Lease Agreement to be kept and
performed by the Lessor shall be expressly assumed in writing by the corporation
resulting from such consolidation or surviving such merger or to which the
Project shall be transferred in its entirety.

         Section 9.4 Redemption of Bonds. If at any time the Lessee shall
deposit with the Trustee monies which, under any terms of the Indenture, are
sufficient to redeem all or part of the principal amount of the Bonds and to pay
any applicable redemption premium plus the fees and expenses of the Trustee in
connection with such redemption, the Lessor, at the request of Lessee, shall
forthwith take all steps necessary under the applicable redemption provisions of
the Indenture to effect redemption of the Bonds requested by the Lessee on a
redemption date selected by the Lessee.

         Section 9.5 Reference to Bonds Ineffective After Bonds Paid. Upon
payment in full of the Bonds (or provisions for payment thereof having been made
in accordance with the provisions of the Indenture) and payment of all fees and
charges of the Trustee, and reimbursement to the Letter of Credit Bank of all
sums drawn under the Letter of Credit, together with interest thereon and all
other sums due and payable to the Bank under the Credit Agreement, and the
termination of the Letter of Credit, all references in this Lease Agreement to
the Bonds and the Trustee and the Bank shall be ineffective and neither the
Trustee, the Bank nor the holders of any of the Bonds shall thereafter have any
rights hereunder, saving and excepting those that shall have theretofore vested.

indebtedness of the Lessee to the Trustee shall be a default under this Lease
Agreement. Any acceleration under this Lease Agreement shall also require an
acceleration under any other indebtedness of the Lessee to the Trustee, and any
acceleration under any other indebtedness of the Lessee to the Trustee shall
require an acceleration under this Ageement.

         Section 10.2 Remedies on Default. Subject to Section 10.6 hereof,
whenever any event of default referred to in Section 10.1 hereof shall have
happened and be continuing, the Lessor may take any one or more of the following
remedial steps:

         (a) By written notice to the Lessee, the Lessor may declare all

Lease Term to be immediately due and payable, whereupon the same shall become
immediately due and payable.

         (b) The Lessor or the Trustee on its own behalf or on behalf of the
Lessor, may re-enter and take possession of the Project without terminating this
Lease Agreement, and sublease the Project for the account of the Lessee, holding

such sublessee in such subleasing and the rents and other amounts payable by the
Lessee hereunder.

         (c) The Lessor or the Trustee on its own behalf or on behalf of the
Lessor may terminate the Lease Term, exclude the Lessee from possession of the
Project and use its best efforts to lease the Project to another party for the

due up to the effective date of such leasing and for the difference in the
amounts payable by such new lessee and the amounts payable by the Lessee under
this Lease Agreement.

         (d) In the event any of the Bonds shall at the time be outstanding and
unpaid, the Lessor may have access to, and inspect and examine and make copies
of the Lessee's books and records and all of its accounts.

         (e) The Lessor may take whatever action at law or in equity may appear
necessary or desirable to collect the rent, then due and thereafter to become
due, or to enforce performance and observance of any obligation, agreement or
covenant of the Lessee under this Lease Agreement.

         The Lessee acknowledges and understands that any lease or sublease
agreement entered into by the Lessor or the Trustee pursuant to either of
Subsections (b) or (c) of this Section 10.2 shall, if the Lessor and the Trustee
deem it advisable, grant an option to purchase the Project to the new lessee or
the sublessee on the terms and conditions acceptable to the Lessor and the
Trustee.

         Any amounts collected pursuant to action taken under this Section 10.2
shall be paid to the Trustee and applied in accordance with the provisions of

instructions of the Bank or the Trustee in the election or pursuit of any
remedies herein vested in it.

         Section 10.3 No Remedy Exclusive. Subject to Section 10.6 hereof, no
remedy herein conferred upon or reserved to the Lessor is intended to be
exclusive of any other available remedy or remedies, but each and every such
remedy shall be cumulative and shall be in addition to every other remedy given
under this Lease Agreement, or now or hereafter existing at law or in equity or
statute. No delay or omission to exercise any right or power shall be construed
to be a waiver thereof, but any such right and power may be exercised from time
to time and as often as may be deemed expedient. In order to entitle the Lessor
to exercise any remedy reserved to it in this Article X, it shall not be
necessary to give any notice, other than such notice as may be herein expressly
required. Such rights and remedies of the Lessor hereunder shall also extend to
the Trustee, and the Trustee and the holders of the Bonds, subject to the
provisions of the Indenture, shall be entitled to the benefit of all covenants
and agreements hereof.

         Section 10.4 Agreement to Pay Attorneys' Fees and Expenses. In the
event the Lessee should default under any of the provisions of this Lease
Agreement, and the Lessor or the Trustee should employ attorneys or incur other
expenses for the collection of amounts payable hereunder or the enforcement,
performance or observance of any obligation or agreement on the part of the
Lessee herein set forth, the Lessee agrees, on demand therefor, to pay to the
Lessor or the Trustee the reasonable fee of such attorney or attorneys and such
other expenses so incurred by the Lessor or the Trustee.

         Section 10.5 No Additional Waiver Implied by One Waiver. In the event
any obligation in this Lease Agreement is breached by either party and
thereafter waived by the other party, such waiver shall be limited to the
particular breach so waived and shall not be deemed to waive any other breach
hereunder.

         Section 10.6 Remedial Rights Assigned to Trustee. All rights and
remedies conferred upon or reserved to the Lessor in this Article X shall, upon
the execution and delivery of the Indenture, be deemed to have been assigned to
the Trustee and the Trustee shall have the exclusive right to exercise such
rights and remedies in the same manner and under the limitations and conditions
that the Trustee is entitled to exercise rights and remedies upon the occurrence
of an Event of Default pursuant to Article 10 of the Indenture.

options to cancel or terminate the term of this Lease Agreement:

         (a) At any time prior to full payment of the Bonds (or provisions for

Indenture), the Lessee may terminate the term of this Lease Agreement and
exercise the option to purchase granted in Section 11.2 hereof by paying to the
Trustee for the account of the Lessor an amount of cash which will be sufficient

to the condition thereof immediately preceding such damage or destruction, or
(ii) the Lessee is thereby prevented from carrying on its normal operations at

pursuant to the requirements of Section 6.4 hereof, plus the amounts for which
the Lessee is self-insured with respect to deductible amounts permitted under
Section 6.5 hereof;

         (b) Title to, or the temporary use of the Project, or any part thereof,
or the leasehold estate of the Lessee in the Project created by this Lease

corporation acting under governmental authority which results, or is likely to

operations therein for a period of four months or more;

         (c) As a result of any changes in the Constitution of the State or the
Constitution of the United States of America or of legislative or administrative
action (whether state or federal) or by final decree, judgment or order of any
court or administrative body, whether state or federal, entered after the
contest thereof by the Lessee in good faith, this Lease shall have become void

         Lease Agreement remains in effect, plus all costs and expenses incurred
         by the Lessor relative to the exercise of the option.

which the Lessee shall have the option to terminate this Lease Agreement
pursuant to Section 11.1(a) hereof, by paying to the Lessor a purchase price in
an amount equal to the sum of one-tenth of one percent (.1%) of the original
principal amount of the Bonds (i.e., $7,500,000) for each year (or portion of a
year) that the Lease Agreement remains in effect, plus all costs and expenses

         Section 11.4 Option to Purchase Unimproved Land. Prior to payment in
full of the Bonds, the Lessee shall have, and is hereby granted, the option to
purchase any Unimproved part of the Leased Land at any time, and from time to
time, at and for a purchase price equal to the fair market value thereof
provided that it furnishes the Lessor with the following:

                  (a) A notice in writing setting forth (i) an adequate legal
         description of that portion of the Leased Land with respect to which
         such option is to be exercised, and (ii) a statement that the Lessee
         intends to exercise its option to purchase such portion of the Leased

         be devoted will be in furtherance of the purpose for which the Lessor
         was organized;

                  (b) A certificate of an Independent Engineer acceptable to the
         Trustee, dated no more than ninety (90) days prior to the date of the
         purchase, stating that, in the opinion of the person signing such
         certificate, (i) the portion of the Leased Land with respect to which
         the option is exercised is not needed for the operation of the Project
         for the purposes hereinabove stated, and (ii) the purchase will not
         impair the usefulness of the Building and will not destroy the means of
         ingress thereto and egress therefrom;

                  (d) An amount of money equal to the fair market value of the
         real property to be purchased or as agreed.

         Upon receipt of the notice, certificate and money required in this
section to be furnished to it by the Lessee, the Lessor will promptly deliver
the same to the Trustee, will cause the Trustee to apply said money as a partial
redemption of the Bonds in accordance with the terms of the Indenture and will
secure from the Trustee a release from the security interest afforded by the
terms of the Indenture of such portion of the Leased Land with respect to which
the Lessee shall have exercised the option granted in this section. In the event
the Lessee shall exercise such option, the Lessee shall not be entitled to any
abatement or diminution of the amounts payable under Section 5.3 hereof.

         The Lessee may, at the Lessee's own expense, connect utility and other
similar facilities serving the Project to utility and other similar facilities
serving real property adjacent to or near the Leased Land, or partly on such
adjacent real property and partly on the Leased Land, but only if the Lessee
furnishes the Lessor and the Trustee a certificate by an Independent Engineer
who is acceptable to the Trustee, certifying that such connection of utility or
other similar facilities will not unreasonably interfere with the use of the
Project.

         Section 11.5 Conveyance on Exercise of Option to Purchase. At the
closing of the purchase pursuant to the exercise of any option to purchase
granted herein, the Lessor will, upon receipt of the purchase price, deliver to
the Lessee documents conveying to the Lessee good and marketable title to the
property with respect to which such option was exercised, as such property then
exists, subject to the following: (i) those liens and encumbrances, if any, to
which title to said property was subject when conveyed to the Lessor; (ii) those
liens and encumbrances created by the Lessee, or to the creation or suffering of
which the Lessee consented; (iii) those liens and encumbrances resulting from
the failure of the Lessee to perform or observe any of its obligations in this
Lease Agreement; and (iv) Permitted Encumbrances other than the Indenture and
this Lease Agreement.

         Section 11.6 Effect of Exercise on Options. Upon the exercise of any
option provided in this Article XI, the matured or accrued obligations of the
Lessee to the Lessor hereunder not theretofore performed, shall survive.

granted to the Lessee in this Article XI, shall be and remain prior and superior
to the Indenture and may be exercised whether or not the Lessee is in default
hereunder, provided that such default will not result in the non-fulfillment of
any condition to the exercise of such option.
