         SECTION 2.01. FORM, TERMS, SERIES AND DATING. The Notes shall be
issued in book-entry form without physical certificates. Notes issued in
book-entry form shall be deemed to include the terms of the form of Note
included as Exhibit A hereto. The Trustee may, upon direction of the Company
made in the sole discretion of the Company, issue definitive physical
certificates to represent one or more Notes. The holders of Notes in
book-entry form shall have no right to demand definitive physical
certificates be issued to represent their Notes.

         In the event Notes are issued in definitive form, the definitive
Notes and the Trustee's certificate of authentication shall be substantially
in the form of Exhibit A, which is incorporated in and made part of this
Indenture, with such insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture. The Notes may have
notations, legends or endorsements required by law, stock exchange rules,
agreements to which the Company is subject or usage. The Company shall
approve the form of the Notes and any notation, legend or endorsement on
them. Each Note shall be dated the date of its authentication.

         The definitive Notes, if any, shall be printed, lithographed or
engraved or produced by any combination of these methods on steel engraved
borders or may be produced in any other manner permitted by the rules of any
securities exchange on which the Notes may be listed, all as determined by
the Company.

         The Notes issued to former Cap Source I investors will be issued,
known and designated as the Variable Rate Junior Notes Callable on or After
the Date of Issuance, due January 15, 2008, Series A. The Notes issued to
former Cap Source II investors will be issued, known and designated as the
Variable Rate Junior Notes Callable on or After the Date of Issuance, due
January 15, 2008, Series B. Unless the context indicates otherwise, the term
"Notes" used herein shall refer to both Series A and Series B Notes. The
Maturity Date of the Notes shall be January 15, 2008 and the Notes shall bear
interest on the unpaid Principal at the Applicable Variable Rate. The Notes
shall be payable as follows:

                  (a)      annual installments of accrued interest, payable on
         each Interest Payment Date, commencing January 15, 2001, and continuing
         until the entire interest and Principal of each Note is paid in full;
         and

                  (b)      the unpaid Principal balance on the Maturity Date.

         The Principal of and interest on the Notes shall be payable at the
principal corporate office of the Paying Agent in Troy, Michigan, or of any
successor or co-Paying Agent; PROVIDED, HOWEVER, that installments of
interest, and, if applicable, Principal may be payable by check mailed to the
address of the person entitled thereto as such address shall appear on the
Notes Register, or for Holders of Notes aggregating more than $1,000,000 in
Outstanding Principal amount who have given written notice and wire transfer
instructions to the Paying Agent, by wire transfer.

         Interest and Principal shall be payable on any Interest Payment Date
or Maturity Date only to those Holders whose names and addresses are listed
on the Notes Register at the close of business on the applicable Record Date.

         The Notes shall bear interest first, at the Initial Interest Rate
during the Initial Interest Rate Period, payable on January 15, 2001.
Thereafter, the Notes shall bear interest for each subsequent Interest Rate
Period, at the Applicable Variable Rate, which shall be a rate per annum
equal to 120% of the Applicable Federal Rate for debt instruments with a term
of not over three years, and which interest rate shall be determined by the
Paying Agent each Interest Determination Date. The interest rate applicable
to any Interest Rate Period, shall become effective on the Interest Payment
Date that is the first day of such Interest Rate Period. Interest on the
Notes shall be borne from and including January 1, 2001, until payment of the
principal or redemption price thereof shall have been made or provided for in
accordance with the provisions hereof, whether at maturity, upon redemption
prior to maturity or otherwise. Interest on the Notes shall be computed on
the basis of a year of 360 days, for the actual number of days elapsed.

         SECTION 2.02. EXECUTION AND AUTHENTICATION. In the event Notes are
issued in definitive form, two Officers shall sign the Notes for the Company
by manual or facsimile signature. In the event Notes are issued in definitive
form, the Company's seal shall be reproduced by facsimile on the Notes. If an
Officer whose signature is on a Note no longer holds that office at the time
the Trustee authenticates the Note, the Note shall be valid nevertheless.

                                      9

<PAGE>

         A Note in definitive physical form shall not be valid until the
Trustee manually signs the certificate of authentication on the Note. The
signature shall be conclusive evidence that the Note has been authenticated
under this Indenture.

         The Trustee may authenticate Notes for original issue in an
aggregate Principal amount of up to $10,000,000 for Series A and $10,000,000
for Series B upon a written Officer's Certificate of the Company. The
Officer's Certificate shall specify the Principal amount of Notes to be
authenticated and the date on which the original issue of Notes is to be
authenticated. The aggregate Principal amount of Notes Outstanding at any
time may not exceed $20,000,000 collectively for Series A and Series B except
as provided in Section 2.07.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate the Notes. If so appointed, an authenticating agent
may authenticate Notes whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by such
agent. An authenticating agent has the same rights as an Agent to deal with
the Company or an Affiliate of the Company.

         The Notes shall be issuable only in registered form without coupons
and only in denominations of $1,000 and any integral multiple thereof.

         SECTION 2.03. REGISTRAR AND PAYING AGENT. The Company shall maintain
an office or agency where Notes may be presented for registration of transfer
or for exchange ("Registrar"), an office or agency where Notes may be
presented for payment ("Paying Agent"), and an office or agency where notices
and demands to or upon the Company in respect of the Notes and this Indenture
may be served. The Registrar shall keep a register of the Notes and of their
transfer and exchange (the "Notes Register"). The Company may have one or
more co-Registrars and one or more additional Paying Agents. The term
"Registrar" includes any co-Registrar and the term "Paying Agent" includes
any additional Paying Agent. Except for purposes of Article IX, the Company
or any Affiliate of the Company may act as Paying Agent.

         The Company may enter into an appropriate agency agreement with any
Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall
notify the Trustee of the name and address of any Agent not a party to this
Indenture. If the Company fails to maintain a Registrar, Paying Agent or
agent for service of notices and demands, or fails to give the foregoing
notice, the Trustee shall act as such.

         The Company initially appoints MMS Escrow and Transfer Agency, Inc.,
a Michigan corporation, as Registrar, Paying Agent and agent for service of
notices and demands.

         SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. Prior to each
Maturity Date or Interest Payment Date of the Principal of or interest on any
Notes, the Company shall deposit with the Paying Agent a sum sufficient to
pay such Principal or interest so becoming due. The Paying Agent shall hold
in trust for the benefit of the Noteholders or the Trustee all money held by
the Paying Agent for the payment of Principal of or interest on the Notes,
and shall notify the Trustee of any Default by the Company (or any other
obligor on the Notes) in making any such payment. If the Company or an
Affiliate of the Company acts as Paying Agent, it shall on or before each
Maturity Date or Interest Payment Date for the Principal of or interest on
any Notes

                                      10

<PAGE>

segregate the money and hold it as a separate trust fund. The Company at any
time may require a Paying Agent to pay all money held by it to the Trustee
and the Trustee may at any time during the continuance of any Default, upon
written request to a Paying Agent, require such Paying Agent to forthwith pay
to the Trustee all sums so held in trust by such Paying Agent. Upon doing so,
the Paying Agent (other than the Company) shall have no further liability for
the money.

         SECTION 2.05. NOTES REGISTER. The Registrar shall preserve in as
current a form as is reasonably practicable a list of the names and addresses
of Noteholders. If the Trustee is not the Registrar, the Company shall
furnish to the Trustee on or before each Interest Payment Date and at such
other times as the Trustee may request in writing a list of such names and
addresses.

         Further, the Company will furnish or cause to be furnished to the
Trustee:

                  (a)      semiannually, and not more than 5 days after each
         Record Date, a list, in such form as the Trustee may reasonably
         require, of the names and addresses of the Holders as of such Record
         Date; and

                  (b)      at such other times as the Trustee may request in
         writing, within 30 days after the receipt by the Company of any such
         request, a list of similar form and content as of a date not more than
         15 days prior to the time such list is furnished;

         Prior to due presentment of a Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Note is registered as the owner of such Note
for the purpose of receiving payment of Principal of and interest on such
Note and for all other purposes whatsoever, whether or not such Note be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

         SECTION 2.06. TRANSFER AND EXCHANGE. When a Note is presented to the
Registrar with a request to register a transfer thereof, the Registrar shall
register the transfer as requested and when Notes are presented to the
Registrar with a request to exchange them for an equal Principal amount of
Notes of other authorized denominations, the Registrar shall make the
exchange as requested; provided that every Note presented or surrendered for
registration of transfer or exchange shall be duly endorsed or be accompanied
by a written instrument of transfer in form satisfactory to the Company and
the Registrar duly executed by the Holder thereof or his attorney duly
authorized in writing. To permit registration of transfers and exchanges, the
Company shall execute and the Trustee shall authenticate Notes at the
Registrar's request. Any exchange or transfer shall be without charge, except
that the Company may require payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto, but this
requirement of payment shall not apply to any exchange pursuant to Section
2.10 or 10.05 not involving any transfer.

         SECTION 2.07. REPLACEMENT NOTES. If a mutilated Note is surrendered
to the Trustee, or if the Holder of a Note claims that the Note has been
lost, destroyed or wrongfully taken, and neither the Company nor the Trustee
has received notice that such Note has been acquired by a bona fide
purchaser, the Company shall issue and the Trustee shall authenticate a
replacement Note if the requirements of Section 8-405, Delaware Code, Title
6, as amended (the Delaware

                                      11

<PAGE>

Uniform Commercial Code), as in effect on the date of this Indenture, are
met, and there shall have been delivered to the Company and the Trustee
evidence to their satisfaction of the loss, destruction or theft of any Note
if such is the case. An indemnity bond may be required that is sufficient in
the judgment of the Company and the Trustee to protect the Company, the
Trustee or any Agent from any loss which any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note. Every
replacement Note is an additional obligation of the Company, and shall be
entitled to all the benefits of this Indenture equally and ratably with any
and all other Notes duly issued hereunder.

         In case any such mutilated, destroyed, lost or stolen Note has
become or is about to become due and payable, the Company, in its discretion,
may pay such Note instead of issuing a new Note.

         SECTION 2.08. OUTSTANDING NOTES. Notes Outstanding at any time are
all Notes authenticated by the Trustee, except for those cancelled by it,
those delivered to it for cancellation and those described in this Section
2.08 as not Outstanding.

         If a Note is replaced pursuant to Section 2.07 hereof, it ceases to
be Outstanding until the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

         If the Paying Agent (other than the Company or an Affiliate of the
Company) holds on a Redemption Date or maturity date money sufficient to pay
the Principal of and accrued interest on Notes payable on that date, then on
and after that date such Notes cease to be Outstanding and interest on them
ceases to accrue.

         A Note does not cease to be Outstanding because the Company or an
Affiliate of the Company holds the Note.

         SECTION 2.09. TREASURY NOTES. In determining whether the Holders of
the required Principal amount of Notes have concurred in any notice,
direction, waiver or consent, Notes owned by the Company or any other obligor
on the Notes or by any Affiliate of the Company or of such other obligor
shall be disregarded, except that for purposes of determining whether the
Trustee shall be protected in relying on any such notice, direction, waiver
or consent, only Notes which the Trustee knows are so owned shall be so
disregarded. Notes so owned which have been pledged in good faith shall not
be disregarded if the pledgee establishes to the satisfaction of the Trustee
the pledgee's right so to act with respect to the Notes and that the pledgee
is not the Company or any other obligor upon the Notes or any Affiliate of
the Company or of such other obligor.

         SECTION 2.10. TEMPORARY NOTES. Until definitive Notes are ready for
delivery, the Company may prepare, and, upon the order of the Company, the
Trustee shall authenticate, temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that
the Company considers appropriate for temporary Notes. Without unreasonable
delay, the Company shall prepare and the Trustee shall authenticate
definitive Notes, which shall then be exchanged for the temporary Notes.
Until so exchanged, the temporary Notes shall be entitled in all respects to
the same benefits under this Indenture as definitive Notes.

                                      12

<PAGE>

         SECTION 2.11. CANCELLATION. The Company at any time may deliver
Notes to the Trustee for cancellation. The Registrar and Paying Agent shall
forward to the Trustee any Notes surrendered to them for transfer, exchange
or payment. The Trustee and no one else shall cancel all Notes surrendered
for transfer, exchange, payment or cancellation. The Company may not issue
new Notes to replace Notes it has paid or delivered to the Trustee for
cancellation.

         SECTION 2.12. DEFAULTED INTEREST. If the Company Defaults in a
payment of interest on the Notes, it shall pay the Defaulted interest to the
Persons who are Noteholders on a subsequent Special Record Date, and such
term as used in this Section 2.12 with respect to the payment of any
Defaulted interest shall mean the fifteenth day next preceding the special
payment date fixed by the Company, whether or not such day is a Business Day.
At least 15 days before any Special Record Date, the Company shall mail to
each Noteholder and the Trustee a notice that states the Special Record Date,
the special payment date and the amount of Defaulted interest to be paid.

                                   ARTICLE III

                                   REDEMPTION

         SECTION 3.01. OPTIONAL REDEMPTION. The Company, at its option
exercised at any time after the execution of this Indenture, may redeem all,
or from time to time any part of, the Notes upon written notice as set forth
in Sections 3.03 and 11.02. The Redemption Price for the Notes to be redeemed
shall be paid by the Company to the Paying Agent on or before the Redemption
Date, and by the Paying Agent to the Noteholder(s) on the Redemption Date.
Amounts distributed to Noteholders in accordance with the settlement
agreement (the "Settlement Agreement") described in the Prospectus shall
constitute partial prepayment of the Notes, and the principal amount
Outstanding under each series of Notes shall be reduced accordingly, pro rata
for each series, upon payment of such amounts. The Company and the Paying
Agent shall give notice to the Trustee within 15 days following payment to
the Noteholders of the Redemption Price under this Section 3.01, if any, and
the amounts paid under the Settlement Agreement.

         SECTION 3.02. MANDATORY PREPAYMENT. The Company shall utilize 80% of
the Net Proceeds of any Sale or Refinancing of Cap Source I Designated
Assets, which occurs after the Transaction, to redeem the maximum number of
Series A Notes which can be redeemed with 80% of such Net Proceeds, and shall
utilize 80% of the Net Proceeds of any Sale or Refinancing of Cap Source II
Designated Assets, which occurs after the Transaction, to redeem the maximum
number of Series B Notes which can be redeemed with 80% of such Net Proceeds;
provided, that such Net Proceeds of any Sale or Refinancing of Designated
Assets shall be accumulated by the Trustee in a segregated trust account for
each series of Notes until the amount in the applicable account benefiting
the affected series of Notes is at least $5,000,000 before redeeming Notes.
Notwithstanding any other remedy for an Event of Default hereunder or
otherwise, the Series A Notes shall have a first priority claim to the funds
in any such trust account segregated for the benefit of Series A Noteholders
until the Series A Notes are paid in full and the Series B Notes shall have a
first priority claim to the funds in any such trust account segregated for
the benefit of Series B Noteholders until the Series B Notes are paid in
full. The Company may, in its sole discretion, waive such $5,000,000
accumulation amount and direct the Trustee or Paying Agent to use 80% of such
Net Proceeds to redeem Notes immediately. The Company shall fix a

                                      13

<PAGE>

Redemption Date pursuant to this Section 3.02 which is no later than 90 days
following receipt of such net proceeds or the accumulation of $5,000,000, as
the case may be.

         This mandatory redemption will be made on Notes, chosen by lot by
the Trustee, until all of the Notes of the applicable series are paid in full
and redeemed.

         Such mandatory redemption is not at the discretion of the Company or
of the Holders of the Notes.

         Any Default in the prepayment provisions of this Section 3.02 with
respect to only one series of Notes shall not constitute an Event of Default
with respect to the other series of Notes.

         SECTION 3.03. NOTICE OF REDEMPTION; PARTIAL REDEMPTION. At least 30
days but not more than 60 days before a Redemption Date, the Company, or the
Trustee at the written direction of the Company, shall mail a notice of
redemption by first-class mail, postage prepaid, to each Holder of Notes
which are to be redeemed pursuant to Section 3.01 or Section 3.02 hereof.

         The notice shall state:

                  (a)      the Redemption Date;

                  (b)      the Redemption Price;

                  (c)      the name and address of the Paying Agent;

                  (d)      that if the Notes being redeemed are represented by
         physical certificates, the certificates must be surrendered to the
         Paying Agent to collect the Redemption Price; and

                  (e)      that, unless the Company Defaults in making the
         redemption payment, interest on the Notes called for redemption ceases
         to accrue on and after the Redemption Date and the only remaining right
         of the Holder is to receive payment of the Redemption Price upon
         surrender to the Paying Agent of the Notes.

         At the Company's written request, the Trustee shall give the notice
of redemption in the Company's name and at the Company's expense.

         If less than all the Notes are to be redeemed, the Trustee shall
select the Notes to be redeemed by lot in whatever manner the Trustee
determines to be efficient and fair. The Trustee shall promptly notify the
Company in writing of the Notes selected for redemption. For all purposes of
this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Notes shall relate, in the case of any Note
redeemed or to be redeemed only in part, to the portion of the Principal
amount of such Note which has been or is to be redeemed.

         SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION. Once notice of
redemption is mailed, the subject Notes will become due and payable on the
Redemption Date at the Redemption Price. Upon surrender to the Paying Agent,
such Notes shall be paid at the Redemption Price.

                                      14

<PAGE>

         Any notice which is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives the notice. Failure to give notice by mail, or any defect in the
notice to the Holder of any Note designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of
any other Note.

         SECTION 3.05. DEPOSIT OF REDEMPTION PRICE. On or before the
Redemption Date, the Company shall deposit with the Paying Agent (or, if the
Company is its own Paying Agent, shall segregate and hold in trust) money
sufficient to pay the Redemption Price of all Notes to be redeemed on that
date, other than Notes or portions thereof called for redemption on that date
which have been delivered by the Company to the Trustee for cancellation.

         On and after the Redemption Date (unless the Company shall Default
in the payment of such Notes at the Redemption Price), interest on the Notes
or portions of Notes so called for redemption shall cease to accrue and,
except as provided in Section 9.01 hereof, such Notes shall cease from and
after the Redemption Date to be entitled to any benefit or security under
this Indenture, and the Holders thereof shall have no right in respect of
such Notes except the right to receive the Redemption Price thereof.

                                   ARTICLE IV

                               PAYMENT PROVISIONS

         SECTION 4.01. NOTES PART OF JUNIOR INDEBTEDNESS. The Notes shall be
on a par with, and part of, the Junior Indebtedness of the Company. In
addition, subject to Section 3.02, all Series A Notes and Series B Notes rank
as to payment of Principal and interest equally and ratably, without priority
one over the other.

         SECTION 4.02. OBLIGATIONS OF THE COMPANY UNCONDITIONAL. Nothing
contained in this Article IV or elsewhere in this Indenture or in any Note is
intended to or shall impair, as among the Company, its creditors and the
Holders, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders the Principal of and interest on the Notes, as and when
the same shall become due and payable in accordance with the terms of the
Notes, or to affect the relative rights of the Holders and other creditors of
the Company nor shall anything herein or therein prevent the Trustee or any
Holder from exercising all remedies otherwise permitted by applicable law
upon the happening of an Event of Default under this Indenture, subject to
the provisions of Article VII. Nothing contained in this Article IV or
elsewhere in this Indenture or in the Notes shall, except during the pendency
of any dissolution, winding-up, liquidation or reorganization of the Company,
affect the obligation of the Company to make, or prevent the Company from
making, at any time payment of Principal of or interest on the Notes.

         The Company shall give prompt notice to the Trustee of any
dissolution, winding-up, liquidation or reorganization of the Company.

         SECTION 4.03. APPLICATION BY TRUSTEE OF MONEYS DEPOSITED WITH IT.
Subject to Sections 7.10 and 8.07, Money or U.S. Government Obligations
deposited in trust with the Trustee pursuant to and in accordance with
Sections 5.04 and 9.01 hereof shall be for the sole benefit of Noteholders.

                                      15

                                    ARTICLE V

                                    COVENANTS

         SECTION 5.01. PAYMENT OF NOTES. The Company shall pay the Principal of
and interest on the Notes on the dates and in the manner provided in the Notes
and this Indenture. An installment of Principal or interest shall be considered
paid on the date it is due if the Paying Agent (other than the Company or an
Affiliate of the Company) holds on that date money designated for and sufficient
to pay the installment. The Company shall pay interest on overdue Principal at
the interest rate per annum borne by the Notes; it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

         SECTION 5.02. SEC REPORTS. The Company shall file all reports and other
information and documents which it is required to file with the SEC pursuant to
Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and within 15 days after it files them with the SEC, the
Company shall file copies of all such reports, information and other documents
with the Trustee. The Company will cause any quarterly and annual reports which
it mails to its stockholders to be mailed to the Holders of the Notes.

         If the Company is not subject to the reporting requirements of Section
13 or Section 15(d) of the Exchange Act, the Company will prepare, for the first
three quarters of each fiscal year, quarterly financial statements substantially
equivalent to the financial statements required to be included in a report on
Form 10-Q under the Exchange Act. The Company will also prepare, on an annual
basis, complete audited consolidated financial statements including, but not
limited to, a balance sheet, a statement of income and retained earnings, a
statement of changes in financial position and all appropriate notes, along with
a "Management's Discussion and Analysis of Financial Condition and Results of
Operations." All such financial statements will be prepared in accordance with
generally accepted accounting principles consistently applied, except for
changes with which the Company's independent accountants concur, and except that
quarterly statements may be subject to year-end adjustments. The Company will
cause a copy of such financial statements to be filed with the Trustee and
mailed to the Holders of the Notes within 15 days after the date the Company
would have been required to file such information with the SEC. The Company will
also comply with the other provisions of TIA Section 314(a).

         SECTION 5.03. WAIVER OF USURY DEFENSE. The Company agrees that it will
not assert, plead (as a defense or otherwise) or in any manner whatsoever claim
(and will actively resist any attempt to compel it to assert, plead or claim) in
any action, suit or proceeding that the interest rate on the Notes violates
present or future usury or other laws relating to the interest payable on any
indebtedness and will not otherwise avail itself (and will actively resist any
attempt to compel it to avail itself) of the benefits or advantage of such laws.

         SECTION 5.04. LIQUIDATION. The General Partner or the Unitholders of
the Company may not adopt a plan of liquidation which plan provides for,
contemplates or the effectuation of which is preceded by (a) the sale, lease,
conveyance or other disposition of all or substantially all of the assets of the
Company otherwise than substantially as an entirety (Article 6 of this Indenture
being the Article which governs any such sale, lease, conveyance or other
disposition

                                     16

<PAGE>

substantially as an entirety), and (b) the distribution of all or
substantially all of the proceeds of such sale, lease, conveyance or other
disposition and of the remaining assets of the Company to the holders of the
Units of the Company, unless the Company shall in connection with the
adoption of such plan make provision for, or agree that prior to making any
liquidating distributions it will make provision for, the satisfaction of the
Company's obligations hereunder and under the Notes as to the payment of the
Principal and interest. The Company shall be deemed to make provision for
such payments only if (1) the Company irrevocably deposits in trust with the
Trustee money and/or U.S. Government Obligations maturing as to Principal and
interest in such amounts and at such times as are sufficient, without
consideration of any reinvestment of such interest, to pay the Principal of
and interest on the Notes then Outstanding to maturity and to pay all other
sums payable by it hereunder, or (2) there is an express assumption of the
due and punctual payment of the Company's obligations hereunder and under the
Notes and the performance and observance of all covenants and conditions to
be performed by the Company hereunder, by the execution and delivery of a
supplemental indenture in form satisfactory to the Trustee by a Person who
acquires, or will acquire (otherwise than pursuant to a lease) a portion of
the assets of the Company, and which Person will have assets (immediately
after the acquisition) and aggregate earnings (for such Person's four full
fiscal quarters immediately preceding the acquisition) equal to not less than
the assets of the Company (immediately preceding the acquisition) and the
aggregate earnings of the Company (for its four full fiscal quarters
immediately preceding such acquisition), respectively, and which Person is a
corporation or partnership organized under the laws of the United States, any
state thereof or the District of Columbia; provided, however, that the
Company shall not make any liquidating distribution until after the Company
shall have certified to the Trustee with an Officers' Certificate at least
five days prior to the making of any liquidating distribution that it has
complied with the provisions of this Section 5.04.

         SECTION 5.05. COMPLIANCE CERTIFICATES. The Company shall deliver to the
Trustee within 120 days after the end of each fiscal year of the Company, an
Officers' Certificate stating whether or not the signers know of any Default or
Event of Default. If they do know of such a Default or Event of Default, the
Certificate shall describe the Default or Event of Default and the efforts to
remedy the same. The Certificate need not comply with Section 11.04.

         SECTION 5.06. NOTICE OF DEFAULTS. In the event that any indebtedness of
the Company is declared due and payable before its maturity because of the
occurrence of any Default under such indebtedness, the Company will promptly
give written notice to the Trustee of such declaration or of the occurrence of
any event which, with the giving of notice or the passage of time, or both,
would entitle the holder or holders of such indebtedness to declare such
indebtedness due and payable before its maturity.

         SECTION 5.07. PAYMENT OF TAXES AND OTHER CLAIMS. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all material taxes, assessments and governmental charges levied
or imposed upon the Company, directly or by reason of its ownership of any
Subsidiary or upon the income, profits or property of the Company; and (2) all
material lawful claims for labor, materials, and supplies, which, if unpaid,
might by law become a lien upon the property of the Company; provided, however,
that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such

                                     17

<PAGE>

tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which adequate provision has been made.

         SECTION 5.08. VALID EXISTENCE. Subject to Section 5.04 and Article 6
hereof, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its partnership existence and rights (charter
and statutory); provided, however, that the Company shall not be required to
preserve any right if the General Partner shall determine that the preservation
is no longer desirable in the conduct of the Company's business and that the
loss thereof is not, and will not be, adverse in any material respect to the
Holders.

         SECTION 5.09. MAINTENANCE OF PROPERTIES. Subject to Section 5.04, the
Company will cause all material properties owned, leased or licensed in the
conduct of its business to be maintained and kept in good condition, repair and
working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof and thereto, all as in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times while any Notes are Outstanding; provided,
however, that nothing in this Section 5.09 shall prevent the Company from
distinguishing the maintenance of any such properties if such discontinuance is,
in the judgment of the General Partner, desirable in the conduct of the
Company's business and is not, and will not be, adverse in any material respect
to the Holders.

         SECTION 5.10. LIMITATIONS ON INDEBTEDNESS. Notwithstanding any
provision herein to the contrary, the Company shall not incur any indebtedness
if such new indebtedness would cause the Aggregate Indebtedness of the Company
then outstanding to exceed 70% of the Appraised Value of the Assets of the
Company.

                                   ARTICLE VI

                                SUCCESSOR ENTITY

         SECTION 6.01. WHEN COMPANY MAY MERGE, ETC. The Company will not, in any
transaction or series of transactions, merge or consolidate with or into, or
sell, assign, transfer, lease or otherwise dispose of all or substantially all
of its properties and assets as an entirety to, any Person or Persons, and the
Company will not permit any of its wholly owned Subsidiaries to enter into any
such transaction or series of transactions if such transactions or series of
transactions, in the aggregate, would result in a sale, assignment, transfer,
lease or other disposition of all or substantially all of the properties and
assets of the Company and its Subsidiaries on a consolidated basis to any other
Person or Persons, unless at the time and after giving effect thereto (i) either
(A) if the transaction or transactions is a merger or consolidation, the Company
shall be the surviving Person of such merger or consolidation, or (B) the Person
formed by such consolidation or into which the Company or such Subsidiary is
merged or to which the properties and assets of the Company or such Subsidiary,
as the case may be, substantially as an entirety, are transferred (any such
surviving Person or transferee Person being the "Surviving Entity") shall be a
corporation organized and existing under the laws of the United States of
America, any state thereof or the District of Columbia and shall expressly
assume by a supplemental indenture executed and delivered to the Trustee, in
form satisfactory

                                        18

<PAGE>

to the Trustee, all the obligations of the Company under the Notes and this
Indenture, and in each case, this Indenture shall remain in full force and
effect; (ii) immediately before and immediately after giving effect to such
transaction or series of transactions on a pro forma basis (including,
without limitation, any Indebtedness incurred or anticipated to be incurred
in connection with or in respect of such transaction or series of
transactions), no Default or Event of Default shall have occurred and be
continuing, and the Company or the surviving entity, as the case may be,
after giving effect to such transaction or series of transactions on a pro
forma basis, could incur $1.00 of additional indebtedness under the first
paragraph of Section 5.10 hereof (assuming a market rate of interest with
respect to such additional Indebtedness); and (iii) immediately after giving
effect to such transaction or series of transactions on a pro forma basis,
the Consolidated Net Worth of the Company or the Surviving Entity, as the
case may be, is at least equal to the Consolidated Net Worth of the Company
immediately before such transaction or series of transactions.

         The Company shall deliver to the Trustee prior to the proposed
transaction an Officers' Certificate and an Opinion of Counsel, each of which
shall comply with Section 11.04 and each of which shall state in effect that
such consolidation, merger or transfer comply with this Article 6 and that all
conditions precedent herein provided for relating to such transaction have been
complied with.

         SECTION 6.02. SUCCESSOR ENTITY SUBSTITUTED. Upon any consolidation or
merger, or any transfer of all or substantially all of the assets of the Company
in accordance with Section 6.01, the successor entity formed by such
consolidation or into which the Company is merged or to which such transfer is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company under this Indenture with the same effect as if such
successor entity had been named as the Company herein.

                                   ARTICLE VII

                              DEFAULT AND REMEDIES

         SECTION 7.01.  EVENTS OF DEFAULT.  An "Event of Default" shall occur
hereunder if:

                  (1)      the Company Defaults in the payment of interest on
         any Note when the same becomes due and payable and the Default
         continues for a period of 30 days;

                  (2)      the Company Defaults in the payment of the Principal
         of any Note when the same becomes due and payable at maturity, upon
         redemption or otherwise;

                  (3)      the Company fails to comply with any of its other
         agreements contained in the Notes or this Indenture and the Default
         continues for the period and after the notice specified below;

                  (4)      there shall be a Default under any bond, debenture,
         note or other evidence of indebtedness for money borrowed or under any
         mortgage, indenture or other instrument under which there may be issued
         or by which there may be secured or evidenced any indebtedness for
         money borrowed by the Company or under any guarantee

                                        19

<PAGE>

         of payment by the Company of indebtedness for money borrowed,
         whether such indebtedness or guarantee now exists or shall
         hereafter be created, which Default relates to (A) the obligation
         to pay the Principal of or interest on any such indebtedness or
         guarantee or (B) an obligation other than the obligation to pay the
         Principal of or interest on any such indebtedness and the effect of
         such Default is to cause such indebtedness to become due prior to
         its stated maturity; provided, however, that no Default under this
         Section 7.01(4) shall exist unless all such Defaults relating to
         such indebtedness or such guarantees aggregate to a Principal
         amount in excess of $25,000,000;

                  (5)      the Company or any Subsidiary pursuant to or within
         the meaning of any Bankruptcy Law: (A) commences a voluntary case or
         proceeding; (B) consents to the entry of an order for relief against it
         in an involuntary case or proceeding; (C) consents to the appointment
         of a Custodian of it or for all or substantially all of its property;
         or (D) makes a general assignment for the benefit of its creditors; or

                  (6)      a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that: (A) is for relief against the
         Company or any Subsidiary in an involuntary case or proceeding; (B)
         appoints a Custodian of the Company or any Subsidiary or for all or
         substantially all of the property of any of them; or (C) orders the
         liquidation of the Company or any Subsidiary; and in each case the
         order or decree remains unstayed and in effect for 60 days.

         A Default under clause (3) of this Section 7.01 shall not become an
Event of Default until the Trustee notifies the Company, or the Holders of at
least 25% in Principal amount of the Notes then Outstanding notify the Company
and the Trustee, of the Default, and the Company does not cure the Default
within 30 days after receipt of such notice; provided, that the 30-day cure
period may be extended for a reasonable time in the discretion of the Trustee or
shall be extended for up to a maximum of 180 days until a cure is accomplished
if the Company begins work on a cure during the 30-day period and diligently
proceeds to accomplish the cure. The notice given pursuant to this Section 7.01
must specify the Default, demand that it be remedied and state that the notice
is a "Notice of Default." When a Default is cured, it ceases.

         Defaults under clauses (2), (4) and (5) of this Section 7.01 shall
become Events of Default immediately, with no waiting period.

         Subject to the provisions of Sections 8.01 and 8.02, the Trustee shall
not be charged with knowledge of any Event of Default unless written notice
thereof shall have been given to a Trust Officer at the corporate trust office
of the Trustee by the Company, the Paying Agent, any Holder or an agent of any
Holder.

         SECTION 7.02. ACCELERATION. If an Event of Default (other than an Event
of Default specified in Section 7.01(5) or (6)) occurs and is continuing, the
Trustee may, by notice to the Company, or the Holders of at least 25% in
Principal amount of the Notes then Outstanding may, by notice to the Company and
the Trustee, and the Trustee shall, upon the request of such Holders, declare
all unpaid Principal of and accrued interest to the date of acceleration on the
Notes then Outstanding (if not then due and payable) to be due and payable and
upon any such declaration, the same shall become and be immediately due and
payable. If an Event of Default

                                        20

<PAGE>

specified in Section 7.01(5) or (6) occurs, all unpaid Principal
and accrued interest on the Notes then Outstanding shall IPSO FACTO
become and be immediately due and payable without any declaration
or other act on the part of the Trustee or any Noteholder. The
Holders of a majority in Principal amount of the Notes then
Outstanding by notice to the Trustee may rescind an acceleration
and its consequences if (i) all existing Events of Default, other
than the non-payment of the Principal of the Notes which has become
due solely by such declaration of acceleration, have been cured or
waived; (ii) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue Principal,
which has become due otherwise than by such declaration of
acceleration, has been paid; (iii) the rescission would not
conflict with any judgment or decree of a court of competent
jurisdiction; and (iv) all payments due to the Trustee and any
predecessor Trustee under Section 9.07 have been made. Anything
herein contained to the contrary notwithstanding, in the event of
any acceleration pursuant to this Section 7.02, the Company shall
not be obligated to pay any premium which it would have had to pay
if it had then elected to redeem the Notes pursuant to paragraph 5
of the Notes. No such rescission shall affect any subsequent
default or impair any right consequent thereon.

         SECTION 7.03. OTHER REMEDIES. 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 payment of the Principal of or interest on the Notes or
to enforce the performance of any provision of the Notes or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder 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 to the
extent permitted by law.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

         SECTION 7.04. WAIVER OF DEFAULT AND EVENTS OF DEFAULT. Subject to
Sections 7.07 and 10.02 hereof, the Holders of a majority in Principal amount of
the Notes then outstanding by notice to the Trustee may waive an existing
Default or Event of Default and its consequences, except a Default in the
payment of the Principal of or interest on any Note as specified in clauses (1)
and (2) of Section 7.01 hereof. When a Default or Event of Default is waived, it
is cured and ceases.

         SECTION 7.05. CONTROL BY MAJORITY. The Holders of a majority in
Principal amount of the Notes then Outstanding may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture,

                                     21

<PAGE>

that the Trustee determines may be unduly prejudicial to the rights
of another Noteholder, or that may involve the Trustee in personal
liability; provided that the Trustee may take any other action
deemed proper by the Trustee which is not inconsistent with such
direction.

         SECTION 7.06.  LIMITATION ON SUITS.  A Noteholder may not pursue any
remedy with respect to this Indenture or the Notes unless:

                  (a)      the Holder has given to the Trustee written notice of
         a continuing Event of Default;

                  (b)      the Holders of at least 25% in Principal amount of
         the Outstanding Notes have made a written request to the Trustee to
         pursue the remedy;

                  (c)      such Holder has offered to the Trustee indemnity
         satisfactory to the Trustee against any loss, liability or expense;

                  (d)      the Trustee has not complied with the request within
         60 days after receipt of the request and the offer of indemnity; and

                  (e)      no direction inconsistent with such written request
         has been given to the Trustee during such 60-day period by the Holders
         of a majority in Principal amount of the Notes then Outstanding.

         A Noteholder may not use this Indenture to prejudice the rights of
another Noteholder or to obtain a preference or priority over such other
Noteholder.

         SECTION 7.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any
other provision of this Indenture, the right of any Holder of a Note to receive
payment of the Principal of or the interest on the Note, on or after the
respective due dates expressed in the Note, or to bring suit for the enforcement
of any such payment on or after such respective dates, is absolute and
unconditional and shall not be impaired or affected without the consent of the
Holder.

         SECTION 7.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default in the
payment of Principal or interest specified in Section 7.01(1) or (2) hereof
occurs and is continuing, the Trustee may recover judgment in its own name and
as trustee of an express trust against the Company or any other obligor on the
Notes for the whole amount of Principal and accrued interest remaining unpaid,
together with interest on overdue Principal and, to the extent that payment of
such interest is lawful, interest on overdue installments of interest, in each
case at the rate per annum borne by the Notes, and such further amount as shall
be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and legal counsel.

         SECTION 7.09. 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 (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and legal counsel) and the Noteholders allowed in any
judicial proceedings relative to the Company (or any other obligor on the
Notes), its creditors or its property and shall be entitled and empowered to
collect and receive any

                                     22

<PAGE>

moneys or other property payable or deliverable on any
such claims and to distribute the same, and any Custodian in any such judicial
proceeding is hereby authorized by each Noteholder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Noteholders, to pay to the Trustee any amount due to it
for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and legal counsel, and any other amounts due the Trustee
under Section 8.07 hereof. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Noteholder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such
proceeding.

         SECTION 7.10. APPLICATION OF MONEY COLLECTED. If the Trustee collects
any money pursuant to this Article 7, it shall pay out the money in the
following order:

                  FIRST: to the Trustee for amounts due under Section 8.07
         hereof;

                  SECOND: to Noteholders for amounts due and unpaid on the Notes
         for Principal and interest, ratably, without preference or priority of
         any kind, according to the amounts due and payable on the Notes for
         Principal and interest, respectively; and

                  THIRD:  to the Company.

The Trustee may fix a Special Record Date and payment date for any payment to
Noteholders pursuant to this Section 7.10.

         SECTION 7.11. UNDERTAKING FOR COSTS. All parties to this Indenture
agree, and each Holder of any Note, by his acceptance thereof shall be deemed to
have agreed, that in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 7.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 7.06 hereof or a suit by Holders of more than 10% in
Principal amount of the Notes then outstanding.

                                  ARTICLE VIII

                                     TRUSTEE

         SECTION 8.01. DUTIES OF TRUSTEE.

                  (a)      If an Event of Default has occurred and is
         continuing, the Trustee shall exercise such of the rights and powers
         vested in it by this Indenture 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 his own affairs.

                                        23

<PAGE>

                  (b)      Except during the continuance of an Event of Default:
         (i) the Trustee need perform only those duties as 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
         therein, upon certificate or opinions furnished to the Trustee and
         conforming to the requirements of this Indenture. The Trustee, however,
         shall examine the certificates and opinions to determine whether or not
         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 8.01; (ii) the Trustee shall
         not be liable for any error of judgment made in good faith by a Trust
         Officer, unless it is proved that the Trustee was negligent in
         ascertaining the pertinent facts; and (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
         7.05 hereof.

                  (d)      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, expense or fee.

                  (e)      Every provision of this Indenture that in any way
         relates to the Trustee is subject to paragraphs (a), (b) (c) and (d) of
         this Section 8.01.

                  (f)      The Trustee shall not be liable for interest on any
         money received by it except as the Trustee may agree with the Company.
         Money held in trust by the Trustee need not be segregated from other
         funds except to the extent required by law.

         SECTION 8.02.  RIGHTS OF TRUSTEE.  Subject to Section 8.01 above:

                  (a)      The Trustee may rely on any document 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 an Officers' Certificate or an Opinion of Counsel, which
         shall conform to Section 11.04(b) hereof. The Trustee shall not be
         liable for any action it takes or omits to take in good faith in
         reliance on such Certificate or Opinion.

                  (c)      The Trustee may act through its agents and shall not
         be responsible for the misconduct or negligence of any agent appointed
         with due care.

                  (d)      The Trustee shall not be liable for any action it
         takes or omits to take in good faith which it reasonably believes to be
         authorized or within its rights or powers.

                  (e)      The Trustee may consult with counsel and the advice
         or opinion of such counsel as to matters of law shall be full and
         complete authorization and protection in respect of any action taken,
         omitted or suffered by it hereunder in good faith and in accordance
         with the advice or opinion of such counsel.

                                       24

<PAGE>

         SECTION 8.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and
may otherwise deal with the Company or an affiliate of the Company with the same
rights it would have if it were not Trustee. Any Agent may do the same with the
like rights. However, the Trustee is subject to Sections 8.10 and 8.11
hereunder.

         SECTION 8.04. TRUSTEE'S DISCLAIMER. The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes and it shall
not be responsible for any statement in the Notes other than the Trustee's
certificate of authentication.

         SECTION 8.05. NOTICE OF DEFAULTS OR EVENTS OF DEFAULT. If a Default or
an Event of Default occurs and is continuing and if it is known to the Trustee,
the Trustee shall mail to each Noteholder written notice of the Default or Event
of Default within 90 days after it occurs. Except in the case of a Default or an
Event of Default in payment of the Principal of (including payment of sinking
fund installments) or interest on any Note, the Trustee may withhold the notice
if and so long as a committee of its Trust Officers in good faith determines
that withholding the notice is in the interest of Noteholders.

         SECTION 8.06. REPORTS BY TRUSTEE TO HOLDERS. Within 60 days after each
May 15 beginning with the May 15 following the date of this Indenture, the
Trustee shall mail to each Noteholder a brief report dated as of such May 15
that complies with TIA Section 313(a). The Trustee also shall mail to each
Noteholder reports which comply with TIA Section 313(b).

         A copy of each report at the time of its mailing to Noteholders shall
be mailed to the Company and filed with the SEC and each stock exchange, if any,
on which the Notes are listed or, in the event the Notes are listed on NASDAQ,
with the National Association of Securities Dealers, Inc., if such filing is
required. The Company shall notify the Trustee whenever the Notes become listed
on any stock exchange or on NASDAQ.

         SECTION 8.07. COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee from time to time reasonable compensation for its services (which
compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust). The Company shall reimburse the
Trustee upon request for all reasonable disbursements, expenses and advances
incurred or made by it. Such expenses may include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

         To secure the Company's payment obligations in this Section 8.07, the
Trustee shall have a senior claim to which the Notes are hereby made subordinate
on all money or property held or collected by the Trustee, except such money or
property held in trust to pay the Principal of and interest on particular Notes.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 7.01(5) and (6) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

         SECTION 8.08. REPLACEMENT OF TRUSTEE. The Trustee may resign by so
notifying the Company; provided, that such resignation shall become effective
only upon the appointment of a successor trustee and such successor's acceptance
of the appointment. The Holders of a majority in Principal amount of the Notes
then Outstanding may remove the Trustee by so notifying the Trustee and may
appoint a successor Trustee with the Company's written consent. The Company may
remove the Trustee if: (a) the Trustee fails to comply with Section 8.10 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 hereunder.

         If the Trustee resigns, is removed by the Company, or is removed by
Holders of a majority in Principal amount of the Notes then Outstanding and such
Holders do not appoint a successor Trustee, or if a vacancy exists in the office
of Trustee for any other reason, the Company shall promptly appoint a successor
Trustee.

         If a successor Trustee does not take office within 45 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of 10% in Principal amount of the Notes then Outstanding may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

         If the Trustee at any time fails to comply with Section 8.10 hereof,
the Trustee shall resign. If the Trustee fails to resign after such an
occurrence, any Noteholder may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee. If the
Trustee has or shall acquire any conflicting interest within the meaning of
Section 310(b) of the TIA with respect to the Notes, it shall either eliminate
such conflicting interest or resign with respect to the Notes, to the extent and
in the manner provided by, and subject to the provisions of, the TIA and this
Indenture.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee, the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers
and duties of the Trustee under this Indenture. A successor Trustee shall mail
notice of its succession to each Noteholder.

         Notwithstanding replacement of the Trustee pursuant to this Section
8.08, the Company's obligations under Section 8.07 hereof shall continue for the
benefit of the retiring Trustee.

                                        26

<PAGE>

         SECTION 8.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all of its corporate trust assets to, another corporation, the resulting,
surviving or transferee corporation without any further act shall be the
successor Trustee, provided such transferee corporation shall qualify and be
eligible under Section 8.10 hereof.

         SECTION 8.10. ELIGIBILITY; DISQUALIFICATION. This Indenture shall
always have a Trustee that satisfies the requirements of TIA Section 310(a)(1).
The Trustee shall have a combined capital and surplus of at least $50,000,000 as
set forth in its most recent published annual report of condition. No obligor
upon the Notes or person directly or indirectly controlling, controlled by, or
under common control with, such obligor shall serve as Trustee for the Notes.
The Trustee shall comply also with TIA Section 310(b).

         SECTION 8.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. If and
when the Trustee becomes a creditor of the Company (or any other obligor on the
Notes), the Trustee shall comply with TIA Section 311(a), excluding from the
operation of TIA Section 311(a) any creditor relationship listed in TIA Section
311(b). A trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated therein.

                                   ARTICLE IX

                     SATISFACTION AND DISCHARGE OF INDENTURE

         SECTION 9.01. TERMINATION OF COMPANY'S OBLIGATIONS. The Company may
terminate all of its obligations under the Notes and this Indenture (except
those obligations referred to in the immediately succeeding paragraph) if all
Notes previously authenticated and delivered (other than destroyed, lost or
stolen Notes which have been replaced or paid or Notes for whose payment money
has theretofore been held in trust and thereafter repaid to the Company, as
provided in Section 9.03 hereof) have been delivered to the Trustee for
cancellation and the Company has paid all sums payable and to be paid by it
hereunder, or if the Company irrevocably deposits in trust with the Trustee
within 10 days of the applicable payment date, money or U.S. Government
Obligations maturing as to Principal and interest in such amounts and at such
times as are sufficient, without consideration of any reinvestment of such
interest, to pay the Principal of and interest on the Notes then Outstanding to
maturity and to pay all other sums payable by it hereunder.

         The Company's obligations in paragraph 12 of the Notes and in Sections
2.03, 2.04, 2.05, 2.06, 2.07, 5.01, 8.07, 8.08 and 9.04 hereof shall survive
until the Notes are no longer Outstanding. Thereafter, the Company's obligations
in such paragraph 12 and in Section 8.07 hereof shall survive.

         After an irrevocable deposit by the Company under this Section 9.01,
the Trustee upon request shall acknowledge in writing the discharge of the
Company's obligations under the Notes and this Indenture, except for those
surviving obligations specified above.

         SECTION 9.02. APPLICATION OF TRUST MONEY. The Trustee or Paying Agent
shall hold in trust, for the benefit of the Holders, money or U.S. Government
Obligations deposited with it pursuant to Section 9.01 hereof, and shall apply
the deposited money and the money from U.S.

                                  27

<PAGE>

Government Obligations in accordance with this Indenture to the
payment of the Principal of and interest on the Notes.

         SECTION 9.03. REPAYMENT TO COMPANY. Subject to Section 9.01, the
Trustee and the Paying Agent shall promptly pay to the Company upon request any
excess money or U.S. Government Obligations held by them at any time after no
Notes remain Outstanding.

         Subject to state escheat or other similar laws, the Trustee and the
Paying Agent shall pay to the Company upon written request any money held by
them for the payment of Principal or interest that remains unclaimed for two
years after a right to such money on the part of Holders of the Notes has
matured; provided, however, that the Trustee or such Paying Agent, before being
required to make any such payment, may at the expense of the Company cause to be
published once in a newspaper of general circulation in the City of New York or
mail to each Holder entitled to such money, notice that such money remains
unclaimed and that after a date specified therein, which shall be at least 30
days from the date of such publication or mailing, any unclaimed balance of such
money then remaining will be repaid to the Company. After payment to the
Company, Noteholders entitled to money must look to the Company for payment as
general creditors unless otherwise prohibited by law.

         SECTION 9.04. REINSTATEMENT. If the Trustee or Paying Agent is unable
to apply any money or U.S. Government Obligations in accordance with Section
9.01 hereof by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 9.01 hereof until such time as the Trustee or
Paying Agent is permitted to apply all such money or U.S. Government Obligations
in accordance with Section 9.01 hereof; provided, however, that if the Company
has made any payment of the Principal of or interest on any Notes because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Notes to receive such payment from the money or U.S.
Government Obligations held by the Trustee or Paying Agent.

                                    ARTICLE X

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

         SECTION 10.01. WITHOUT CONSENT OF HOLDERS. The Company and the Trustee
may amend or supplement this Indenture or the Notes without notice to or consent
of any Noteholder:

                  (a)      to comply with Section 5.04 or 6.01 hereof;

                  (b)      to provide for uncertificated Notes in addition to or
         in place of certificated Notes;

                  (c)      to add covenants and events of default for the
         protection of the Holders of the Notes;

                  (d)      to evidence the acceptance of appointment by a
         successor trustee; or

                                      28

<PAGE>

                  (e)      to cure any ambiguity, defect or inconsistency, or to
         make any other change that does not adversely affect the rights of any
         Noteholder.

         SECTION 10.02. WITH CONSENT OF HOLDERS. The Company and the Trustee may
amend or supplement this Indenture or the Notes without notice to any Noteholder
but with the written consent of the Holders of a majority in Principal amount of
the Notes then Outstanding. The Holders of a majority in Principal amount of the
Notes then Outstanding may waive compliance in a particular instance by the
Company with any provision of this Indenture or the Notes without notice to any
Noteholder. Subject to Section 10.04 hereof, without the consent of each
Noteholder affected, however, an amendment, supplement or waiver, including a
waiver pursuant to Section 7.04 hereof, may not:

                  (a)      reduce the amount of Notes whose Holders must consent
         to an amendment, supplement or waiver;

                  (b)      reduce the rate of or change the time for payment of
         interest on any Note;

                  (c)      reduce the Principal of or change the fixed maturity
         of any Note or alter the redemption provisions with respect thereto;

                  (d)      waive a Default in the payment of the Principal of or
         interest on any Note;

                  (e)      make any changes in Section 7.04 or 7.07 or this
         sentence;

                  (f)      modify the provisions of Article IV hereof in a
         manner adverse to the Holders; or

                  (g)      make any Note payable in money other than that stated
         in the Note.

         It shall not be necessary for the consent of the Holders under this
Section 10.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

         After an amendment, supplement or waiver under this Section 10.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of such amendment, supplement or waiver,
provided that the failure to mail notice does not impair the rights of the
Holders affected thereby.

         SECTION 10.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to
or supplement of this Indenture or the Notes shall comply with the TIA as then
in effect.

         SECTION 10.04. REVOCATION AND EFFECT OF CONSENTS. Until an amendment or
waiver becomes effective, a consent to it by a Holder is a continuing consent by
the Holder and every subsequent Holder of a Note or portion of a Note that
evidences the same debt as the consenting Holder's Note, even if notation of the
consent is not made on any Note. However, any such Holder or subsequent Holder
may revoke the consent as to his Note or portion of a Note if the

                                       29

<PAGE>

Trustee receives the notice of revocation before the date the
amendment, supplement or waiver becomes effective.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Noteholder, unless it makes a change described in any of clauses (a)
through (g) of Section 10.02. In that case the amendment, supplement or waiver
shall bind each Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note.

         SECTION 10.05. NOTATION ON OR EXCHANGE OF NOTES. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee may require the
Holder of the Note to deliver it to the Trustee. The Trustee may place an
appropriate notation on the Note about the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Note shall issue and the Trustee shall authenticate a new
Note that reflects the changed terms.

         SECTION 10.06. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall sign
any amendment or supplement authorized pursuant to this Article X if the
amendment or supplement does not adversely affect the rights, duties,
liabilities or immunities of the Trustee. If it does, the Trustee may but need
not sign it. In signing or refusing to sign such amendment or supplement, the
Trustee shall be entitled to receive and, subject to Section 8.01 hereof, shall
be fully protected in relying upon an Opinion of Counsel stating that such
amendment or supplement is authorized or permitted by this Indenture. The
Company may not sign an amendment or supplement until its General Partner
approves it.

                                  MISCELLANEOUS

         SECTION 11.01. TRUST INDENTURE ACT CONTROLS. If any provision of this
Indenture limits, qualifies or conflicts with another provision which is
required to be included in this Indenture by the TIA, the required provision
shall control; provided, however, that if any provision of this Indenture
modifies or excludes any provision of the TIA that may be so modified or
excluded, such provision as so modified or excluded, as the case may be, shall
control.

         2. METHOD OF PAYMENT. The Company will pay interest on this Note
(except Defaulted interest) to the Person who is the registered Holder of this
Note as listed on the Notes Register maintained by the Registrar, at the close
of business on the Record Date next preceding the Interest Payment Date. The

provided, that Holders of Notes having $1,000,000 or more in aggregate
outstanding Principal amount of Notes may elect to have payments of interest on
the Notes made by wire transfer by providing to the Paying Agent a notice,
together with wire transfer instructions, in form acceptable to the Paying

This Note is subject to all such terms, and the Holder of this Note is referred
to

                                  3

<PAGE>

the Indenture and said Trust Indenture Act for a statement of them. The Notes
are unsecured obligations of the Company limited to $20,000,000 aggregate
Principal amount collectively for both series of Notes.

         5. OPTIONAL REDEMPTION.  The Notes may be redeemed in whole or
in part, at any time, or from time to time, at the option of the Company, at
a price equal to the Principal amount thereof plus accrued and unpaid
interest to the date fixed for redemption.

         6. MANDATORY REDEMPTION. The Company shall utilize 80% of any Net
Proceeds of any Sale or Refinancing of Cap Source I Designated Assets, occurring
at any time after the Transaction, to redeem Series A Notes by lot, to the
extent of such Net Proceeds, and the Company shall utilize 80% of any Net
Proceeds of any Sale or Refinancing of Cap Source II Designated Assets,
occurring at any time after the Transaction, to redeem Series B Notes by lot, to
the extent of such Net Proceeds; provided, that such Net Proceeds of any Sale or
Refinancing of Designated Assets shall be accumulated by the Trustee in a
segregated trust account until the amount therein is at least $5,000,000 before
calling Notes for redemption. The Company shall fix a Redemption Date pursuant
to the Indenture which is no later than 90 days following receipt of such net
proceeds or the accumulation of $5,000,000, as the case may be.

         Such mandatory redemption is not at the discretion of the Company or of
the Holders of the Notes.

         7. NOTICE OF REDEMPTION. Notice of redemption will be mailed by
first-class mail at least 30 days but not more than 60 days before a redemption

On and after the Redemption Date, interest ceases to accrue on Notes or portions
of them called for redemption.

         8. JUNIOR DEBT. The indebtedness evidenced by the Notes is on a par
with, and part of, the Junior Indebtedness of the Company, as defined in the
Indenture.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples thereof. A
Holder may register the transfer of or exchange Notes in accordance with the
Indenture. The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay any taxes or other
governmental charges that may be imposed by law or permitted by the Indenture.

         10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as the owner of it for all purposes.

         11. UNCLAIMED MONEY. Subject to state escheat or other similar laws, if
money for the payment of Principal or interest remains unclaimed for two years,
the Trustee or Paying Agent will pay the money back to the Company at its
request. After that, Holders entitled to money must look to the Company for
payment.

         12. AMENDMENT, SUPPLEMENT, WAIVER. Subject to certain exceptions, the
Indenture may be amended or supplemented with the consent of the Holders of a
majority in Principal amount of the Notes then Outstanding, and any existing
Default or compliance with any

                                      4

<PAGE>

provision may be waived in a particular instance with the consent of the
Holders of a majority in Principal amount of the Notes then Outstanding.
Without the consent of or notice to any Noteholder, the Company and the
Trustee may amend or supplement the Indenture to, among other things, provide
for uncertificated Notes in addition to or in place of certificated Notes, to
cure any ambiguity, defect or inconsistency or make any other change that
does not adversely affect the rights of any Noteholder.

         13. SUCCESSOR COMPANY. When a successor Company assumes all the
obligations of its predecessor Company under the Notes and the Indenture, the
predecessor Company will be released from those obligations.

         14. DEFAULTS AND REMEDIES. An Event of Default is defined in the
Indenture generally as: Default for 30 days in payment of interest on the Notes;
Default in payment of Principal on them; failure by the Company for 30 days
after notice to it to comply with any of its other agreements in the Indenture
or the Notes; certain events of bankruptcy or insolvency of the Company or any
of its Subsidiaries; and certain Defaults on other indebtedness. If an Event of
Default (other than as a result of certain events of bankruptcy or insolvency)
occurs and is continuing, the Trustee or the Holders of at least 25% in
Principal amount of the Notes then Outstanding may declare all unpaid Principal
of and accrued interest to the date of acceleration on the Notes then
Outstanding to be due and payable immediately, all as and to the extent provided
in the Indenture. If an Event of Default occurs as a result of certain events of
bankruptcy or insolvency, all unpaid Principal of and accrued interest on the
Notes then Outstanding shall become due and payable immediately without any
declaration or other act on the part of the Trustee or any Noteholder, all as
and to the extent provided in the Indenture. Noteholders may not enforce the
Indenture or the Notes except as provided in the Indenture. The Trustee may
require indemnity satisfactory to it before it takes action to enforce the
agreements in the Indenture or the Notes. Subject to certain limitations,
Holders of a majority in Principal amount of the Notes then Outstanding may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Noteholders notice of any continuing Default (except a Default in
payment of Principal or interest) if it determines that withholding notice is in
their interests.

         15. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from and perform
services for the Company or an Affiliate of the Company, and may otherwise deal
with the Company or an Affiliate of the Company, as if it were not Trustee.

         16. NO RECOURSE AGAINST OTHERS. A director, officer, employee or
partner, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, or in respect or by reason of, such obligations or their creation. The
holder of this Note by accepting this Note waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
this Note.

         17. DISCHARGE PRIOR TO MATURITY. If the Company deposits with the
Trustee or Paying Agent within 10 days of the payment date, money or U.S.
Government Obligations sufficient to pay the Principal of and interest on the
Notes to maturity, the Company will be discharged from the Indenture except for
certain Sections thereof.
