Debenture Register, not later than the latest date and not earlier than the
earliest date prescribed for the giving of such notice.  In any case where
notice to Debentureholders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Debentureholders.
Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before

filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     United Homes, Inc., a corporation created under the laws of the State of

corporation under the Indenture hereinafter referred to), for value received,
hereby promises to pay to ______________________ or registered assigns, the
principal sum of ______________ Thousand Dollars ($______) on March 15, 2005
(the "Final Maturity Date") and to pay interest hereon from the Original
Interest Accrual Date set forth above, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, beginning on March
15, 1998 ("Initial Interest Payment Date") and on the 15th day of each March,

Debentures) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Principal or Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Debentureholders not less than 10 days

manner not inconsistent with the applicable requirements of any securities
exchange or market on which the Debentures may be listed or included, and upon

other office or agency as may be selected by the Company in accordance with the

time of payment is legal tender for payment of public and private debts,
provided, however, that at the option of the Company payment of interest may be
made in United States dollars by check mailed to the address of the Person
entitled thereto as such address shall appear in the Debenture Register.  THE
HOLDER MUST PRESENT THIS DEBENTURE TO COLLECT PRINCIPAL; AND WHEN FULLY PAID,
THE DEBENTURE SHALL BE SURRENDERED AND CANCELLED.

     Reference is hereby made to the further provisions of this Debenture set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     No recourse shall be had for the payment of the principal or interest of
this Debenture against any Company stockholder, officer, director, employee or
agent by virtue of any statute or by enforcement of any assessment or otherwise;
and any and all liability of stockholders, directors, officers, employees and

SECTION 203.   FORM OF REVERSE SIDE OF DEBENTURE.

     This Debenture is one of a duly authorized issue of 11% Mandatory
Redemption Debentures of the Company designated as its 11% Mandatory Redemption
Debentures (the "Debentures") in the maximum aggregate principal amount of up to
$7,000,000, issued and to be issued under an Indenture, dated as of November 25,
1997 (the "Indenture"), between the Company and National City Bank of
Minneapolis, as Trustee (the "Trustee", which term includes any successor
Trustee under the Indenture).  Reference is hereby made to the Indenture and all
indentures supplemental thereto for a statement of the respective rights,
limitation of rights, duties and immunities thereunder of the Company, the
Trustee and the Debentureholders, and for a statement of the terms upon which
the Debentures are, and are to be, authenticated and delivered.  Capitalized and
certain other terms used herein and not otherwise defined have the meanings set
forth in the Indenture.

     The Debentures are general unsecured obligations of the Company.

     The Debentures are subject to redemption (either at the option of the
Company or upon call by the Trustee) in whole at any time or in part from time
to time.  Beginning on the Initial Amortization Date and semiannually thereafter
until final maturity, the Trustee shall redeem a portion of the Outstanding
Debentures, chosen by lot, at a Redemption Price equal to par, plus interest
accrued to the date of redemption.  The Company may, at its option, at any time
on or after December 15, 1997, redeem the Debentures either as a whole or from
time to time in part in a minimum aggregate principal amount of $100,000, chosen
by lot, at the following Redemption Prices (expressed in percentages of the
principal amount thereof), together with interest accrued and unpaid thereon to

     Notice of redemption will be mailed at least 30 days, but not more than 60
days, before the Redemption Date to the Holder at the registered address
thereof.

     If this Debenture shall be redeemed by call for redemption, and payment be
duly provided therefor as specified in the Indenture, interest shall cease to
accrue on this Debenture.

     Interest installments whose Stated Maturity is on or before the Redemption
Date will be payable to the Holders of such Debentures, or one or more of the
Predecessor Debentures, of record at the close of business on the relevant
Record Date referred to on the face hereof, all as provided in the Indenture.

     If an Event of Default as defined in the Indenture shall occur and be
continuing, the outstanding principal of all the Debentures may be declared due
and payable in the manner and with the effect provided in the Indenture.  The
Company shall pay all costs of collection, whether or not judicial proceedings
are instituted, in the manner provided in the Indenture.  The Indenture provides
that such declaration and its consequences may, in certain events, be annulled
by the Holders of a majority in principal amount of the Debentures Outstanding.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Debentureholders under the Indenture at any time
by the Company and the Trustee with the consent of the Debentureholders of
two-thirds in aggregate principal amount of the Debentures at the time
Outstanding. The Indenture also contains provisions permitting the
Debentureholders of specified percentages in aggregate principal amount of the
Debentures at the time Outstanding, on behalf of the Holders of all of the
Debentures, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Debenture shall be conclusive
and binding upon such Holder and upon all future Holders of this Debenture and
of any Debenture issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Debenture.

     No reference herein to the Indenture and no provision of this Debenture or
of the Indenture or amendment or modification hereof or thereof shall alter or
impair the obligation of the Company to pay the principal of and interest (and
premium, if any) on this Debenture at the times, place and rate and in the coin
or currency herein prescribed.

     In the event of a consolidation or merger of the Company into, or of the
transfer of its assets substantially as an entirety to, a successor corporation
in accordance with the Indenture, such successor corporation shall assume
payment of the Debentures and the performance of every covenant of the Indenture
on the part of the Company, and in the event of any such transfer, the
predecessor corporation shall be discharged from all obligations and covenants
in respect of the Debentures and the Indenture and may be dissolved and
liquidated, all as more fully set forth in the Indenture.

     The Debentures are issuable only in registered form without coupons in
denominations of $1,000 or any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, the Debentures
are exchangeable for a like aggregate principal amount of Debentures of a
different authorized denomination, as requested by the Holder surrendering the
same; and, the transfer of this Debenture is registerable in the Debenture
Register, upon surrender of this Debenture for registration of transfer at the
office or agency of the Company in any place where the principal of and interest
on this Debenture are payable, duly endorsed by or accompanied by a written
instrument of transfer in the form printed on this Debenture or in another form
satisfactory to the Company and the Debenture Registrar duly executed by the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Debentures, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.   No service charge


                                          20
<PAGE>

shall be made for any such registration of transfer or exchange, but the Company
may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.

     Prior to due presentment of this Debenture for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Debenture is registered as the owner hereof for
all purposes, whether or not this Debenture be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

     This Debenture shall be governed by and construed in accordance with the
laws of the State of Minnesota.

     All terms used in this Debenture which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

     The Debentures shall be redeemable at the option of the Company as provided

                                          23
<PAGE>

SECTION 302.   DENOMINATIONS.

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

SECTION 303.   EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

     The Debentures shall be executed on behalf of the Company by its President
or any Vice President and attested by its Secretary or Assistant Secretary.  The
signature of any of these officers on the Debentures may be manual or facsimile.

     Debentures bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Debentures or did not
hold such offices at the date of such Debentures.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Debentures executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Debentures.  The Trustee in accordance with such Company
Order shall authenticate and deliver such Debentures as in this Indenture
provided and not otherwise.

     Upon the initial issuance, each Debenture shall be dated November 25, 1997,
and thereafter, Debentures issued hereunder shall be dated the date of their
authentication.

     No Debenture shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Debenture a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Debenture shall be conclusive evidence, and the only evidence, that such
Debenture has been duly authenticated and delivered hereunder and is entitled to
the benefits of the Indenture.

SECTION 304.   TEMPORARY DEBENTURES.

     Pending the preparation of definitive Debentures, the Company may execute,
and upon Company Order the Trustee shall authenticate and deliver, temporary
Debentures which are printed, lithographed, typewritten, mimeographed or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Debentures, in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Debentures may determine, as evidenced by their
execution of such Debentures.

     If temporary Debentures are issued, the Company will cause definitive
Debentures to be prepared without unreasonable delay. After the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures upon surrender of the


                                          24
<PAGE>

temporary Debentures at any office or agency of the Company designated pursuant
to Section 1002, without charge to the Holder.  Upon surrender for cancellation
of any one or more temporary Debentures, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Debentures of authorized denominations.  Until so exchanged
the temporary Debentures shall in all respects be entitled to the same benefits
under this Indenture as definitive Debentures.

SECTION 305.   REGISTRATION, TRANSFER, AND EXCHANGE.

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office or any other office
or agency pursuant to Section 1002 being herein sometimes referred to as the
"Debenture Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Debentures and of
transfers of Debentures.  The Trustee is hereby appointed "Debenture Registrar"
for the purpose of registering Debentures and transfers of Debentures as herein
provided.

     Upon surrender for registration of transfer of any Debenture at an office
or agency of the Company designated pursuant to Section 1002 for such purpose,
the Company shall execute, and the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Debentures
of any authorized denomination, of a like aggregate principal amount.

     At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Debentures to be exchanged at such office or
agency.  Whenever any Debentures are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Debentures
which the Holder making the exchange is entitle to receive.

     All Debentures issued upon any registration of transfer or exchange of
Debentures shall be valid obligations of the Company, evidencing the same debt
and entitled to the same benefits under this Indenture as the Debentures
surrendered upon such registration of transfer or exchange.

     Every Debenture presented or surrendered for registration of transfer or
for exchange shall be duly endorsed for transfer (if so required by the Company
or the Trustee), or shall be accompanied by a written instrument of transfer in
form satisfactory to the Company and the Debenture Registrar duly executed by
the Holder thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange of Debentures, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Debentures, other than
exchanges pursuant to Section 304 or 905 not involving any transfer.


                                          25
<PAGE>

     The Company shall not be required to issue or register the transfer of any
Debenture during a period beginning at the opening of business 15 days before
the day of the mailing of a notice of redemption of Debentures selected for
redemption pursuant to Section 1106 and ending at the close of business on the
day of such mailing.

SECTION 306.   MUTILATED, DESTROYED, LOST AND STOLEN DEBENTURES.

     If any mutilated Debenture is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Debenture of like series, tenor and principal amount and bearing a number
not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Debenture and (ii)
such security or indemnity as may be required by them to save each of them
harmless, then, in the absence of notice to the Company or the Trustee that such
Debenture has been acquired by a bona fide purchaser, the Company shall execute
and upon its request the Trustee shall authenticate and deliver, in lieu of any
such destroyed, lost or stolen Debenture, a new Debenture of like series, tenor
and principal amount and bearing a number not contemporaneously outstanding.

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

     Upon the issuance of any new Debenture under this Section, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Debenture issued pursuant to this Section in lieu of any
destroyed, lost or stolen Debenture shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Debenture shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture.

     The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debentures.

SECTION 307.   PAYMENTS OF PRINCIPAL AND INTEREST; RIGHTS PRESERVED.

     Any installment of interest or interest and principal under any Debenture
which is payable, and is punctually paid or duly provided for, on any Interest
Payment Date or Principal Payment Date, as the case may be, shall be paid to the
Person in whose name that Debenture (or one or more Predecessor Debentures) is
registered at the close of business on the Regular Record Date for such
installment.

     Any installment of interest or principal and interest on any Debenture
which is payable, but is not punctually paid or duly provided for, on any
Interest Payment Date (herein called "Defaulted Interest") or on any Principal
Payment Date (herein called "Defaulted Principal"), as the case may be, shall
forthwith cease to be payable to the Holder on the relevant Regular Record Date
by virtue of having been such Holder, and such Defaulted Interest or Defaulted
Principal, as the case may be, shall be paid by the Company, at its election in
each case, as provided in paragraph (1) or (2) below:

     (1)  The Company may elect to make payment of any Defaulted Interest or
Defaulted Principal to the Persons in whose names the Debentures (or their
respective Predecessor Debentures) are registered at the close of business on a
Special Record Date for the payment of such Defaulted Interest or Defaulted
Principal, which shall be fixed in the following manner.  The Company shall
notify the Trustee in writing of the amount of Defaulted Interest or Defaulted
Principal proposed to be paid on each Debenture and the date of the proposed
payment and, at the same time, the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of
such Defaulted Interest or Defaulted Principal or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest or Defaulted Principal as in this
Clause provided.  Thereupon the Trustee shall fix a Special Record Date for the
payment of such Defaulted Interest or Defaulted Principal which shall be not
more than 15 days and not less than 10 days prior to the date of the proposed
payment and not less than 10 days after the receipt by the Trustee of the notice
of the proposed payment.  The Trustee shall promptly notify the Company of such
Special Record Date and, in the name and at the expense of the Company, shall
cause notice of the proposed payment of such Defaulted Interest or Defaulted
Principal and the Special Record Date therefor to be mailed, first-class postage
prepaid, to each Holder of an affected Debenture at such Holder's address as it
appears in the Debenture Register, not less than 10 days prior to such Special
Record Date.  Notice of the proposed payment of such Defaulted Interest or
Defaulted Principal and the Special Record Date therefor having been so mailed,
such Defaulted Interest or Defaulted Principal shall be paid to the Persons in
whose names the Debentures (or their respective Predecessor Debentures) are
registered at the close of business on such Special Record Date and shall no
longer be payable pursuant to the following Paragraph (2).

     (2)  The Company may make payment of any Defaulted Interest or Defaulted
Principal in any other lawful manner not inconsistent with the requirements of
any securities exchange or market on which the Debentures may be listed or
included and, upon such notice as may be required by such exchange or market if,
after notice given by the Company to the Trustee


                                          27
<PAGE>

of the proposed payment pursuant to this Clause, such manner of payment shall be
deemed practicable by the Trustee and the Trustee shall have sent written
notification to the Company to such effect.

     If any installment of interest whose Stated Maturity is on or prior to the
Redemption Date for any Debentures called for redemption pursuant to Article
Eleven is not paid or duly provided for on or prior to the Redemption Date in
accordance with the foregoing provisions of this Section, such interest shall be
payable as part of the Redemption Price of such Debentures.

     Subject to the foregoing provisions of this Section, each Debenture
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Debenture shall carry the rights to interest accrued
and unpaid and to accrue which were carried by such other Debenture.

     All payments of interest on the Debentures to the person entitled thereto,
whether made by the Company, the Trustee or any Paying Agent, as authorized
pursuant to this Indenture, shall be made (subject to collection) by check
mailed to the address of the person entitled thereto as such address shall
appear on the Debenture Register, unless the Trustee determines such methods to
be inappropriate in the circumstances.

     Holders must present and surrender the Debentures to collect the principal
of such Debentures.

SECTION 308.   PERSONS DEEMED OWNERS.

     Prior to due presentment of a Debenture for registration of transfer, the
Company, the Trustee, the Debenture Registrar and any agent of the Company or
the Trustee may treat the Person in whose name such Debenture is registered as
the owner of such Debenture for the purpose of receiving payment (subject to
Section 307) of principal of (and premium, if any) and interest on such
Debenture and for all other purposes whatsoever, whether or not such Debenture
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 309.   CANCELLATION.

     All Debentures surrendered for payment, redemption, registration of
transfer or exchange if surrendered to any Person other than the Trustee, shall
be delivered to the Trustee and shall be promptly cancelled by it.  The Company
may at any time deliver to the Trustee for cancellation any Debentures
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Debentures so delivered shall be
promptly cancelled by the Trustee.  No Debentures shall be authenticated in lieu
of or in exchange for any Debentures cancelled as provided in this Section,
except as expressly permitted by this Indenture.  All cancelled Debentures held
by the Trustee shall be disposed of and a destruction certificate shall be
delivered to the Company.

SECTION 310.   COMPUTATION OF INTEREST.

     Interest on the Debentures shall be computed on the basis of a 360-day year
comprised of twelve 30-day months.

SECTION 311.   AUTHENTICATION AND DELIVERY OF ORIGINAL ISSUE.

     Forthwith upon the execution and delivery of this Indenture, or from time
to time thereafter, Debentures up to the aggregate principal amount of
$7,000,000 may be executed by the Company and delivered to the Trustee for
authentication and delivered by the Trustee upon Company Order, without any
further action by the Company.

SECTION 401.   SATISFACTION AND DISCHARGE OF INDENTURE.

     This Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of Debentures herein
expressly provided for), and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

     (1)  either

          (a)  all Debentures theretofore authenticated and delivered (other
than (i) Debentures which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 306 and (ii) Debentures for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter paid to the Company or discharged from such
trust, as provided in Section 1003) have been delivered to the Trustee for
cancellation; or

          (b)  all such Debentures not theretofore delivered to the Trustee for
cancellation (i) have become due and payable, or (ii) will become due and
payable at their Stated Maturity within one year, or (iii) are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company; and the Company, in the case of this subsection (b)
(i), (ii) or (iii) above, has deposited or caused to be deposited with the
Trustee as trust funds in trust for the purpose an amount sufficient to pay and
discharge the entire indebtedness on such Debentures not theretofore delivered
to the Trustee for cancellation, for principal (and premium, if any) and
interest to the date of such deposit (in the case of Debentures which have
become due and payable) or to the Stated Maturity or Redemption Date, as the
case may be;

     (2)  the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

     (3)  the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607 shall survive, and,
if the money shall have been deposited with the Trustee pursuant to subclause
(b) of clause (1) of this Section, the obligations of the Trustee under Section
402 and the last paragraph of Section 1003 shall survive.

SECTION 402.   APPLICATION OF TRUST MONEY.

     All money deposited with the Trustee pursuant to Section 401 shall be held
in trust and applied by it, in accordance with the provisions of the Debentures
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.

SECTION 501.   EVENTS OF DEFAULT.

     "Event of Default," wherever used herein, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

     (1)  default in the payment of any interest upon any Debenture when it

shall have filed with the Trustee a certification of Ernst & Young, LLP, or such
other certified independent public auditor, certifying that such breach has been
cured; or

     (4)  default in the performance, or breach, of any covenant or warranty of
the Company in this Indenture (other than a covenant or warranty default in

after there has been given, by registered or certified mail, to the Company by
the Trustee or to the Company and the Trustee by the Holders of at least 25% in
principal amount of the Outstanding Debentures, a written notice (and the
Trustee shall give such written notice to the Company upon the request of the

GAAP), or a default under any mortgage, indenture or instrument under which
there may be issued or by which there may be secured or evidenced any
Indebtedness of the Company or Subsidiary, (including such leases), whether such
indebtedness now exists or shall hereafter be created, which default shall have
resulted in such indebtedness in excess of $100,000 being declared due and
payable prior to the date on which it would otherwise have become due and
payable or such obligations in excess of $100,000 being accelerated, without
such acceleration having been rescinded or annulled or such Indebtedness shall
not have been discharged within a period of 30 days after such default or
acceleration; provided, however, that this Section 501(5) shall not apply to (a)
a default under any purchase money obligation of


                                          32
<PAGE>

the Company if, and so long as, the Company is in good faith and in the exercise
of its reasonably prudent business judgment, contesting its obligations
thereunder in accordance with a reasonable interpretation of the documentation
of such obligation; or (b) a default in a contractual obligation not otherwise
constituting Indebtedness if and so long as, the Company is in good faith
contesting such obligation and has posted a bond sufficient to pay such
obligation in the event it is determined to be due and payable; or

     (6)  the entry of a decree or order by a court having jurisdiction in the
premises adjudging the Company or any Subsidiary a bankrupt or insolvent, or
approving as properly filed a petition seeking reorganization, arrangement,
adjustment or composition of or in respect of the Company or any Subsidiary,
under Federal bankruptcy law, as now or hereafter constituted, or any other
applicable Federal or State bankruptcy, insolvency or other similar law, or

similar official of the Company or any Subsidiary or of any substantial part of
its property, or ordering the winding up or liquidation of its affairs, and the
continuance of any such decree or order unstayed and in effect for a period of
sixty (60) consecutive days; or

     (7)  the commencement by the Company or any Subsidiary of a voluntary case
under Federal bankruptcy law, as now or hereafter constituted, or any other
applicable Federal or State bankruptcy, insolvency, or other similar law, or the
consent by it to the institution of bankruptcy or insolvency proceedings against
it, or the filing by it of a petition or answer or consent seeking
reorganization or relief under Federal bankruptcy law or any other applicable
Federal or State law, or the consent by it to the filing of such petition or to
the appointment of a receiver, liquidator, assignee, trustee, sequestrator or
similar official of the Company or any Subsidiary or of any substantial part of
its property, or the making by it of an assignment for the benefit of creditors,
or the admission by it in writing of its inability to pay its debts generally as
they become due, or the taking of corporate action by the Company or any
Subsidiary in furtherance of any such action; or

     (8)  the rendering of a final judgment or judgments (not subject to appeal)
for the payment of money against the Company or any Subsidiary not fully insured
against in an aggregate amount in excess of $250,000 by a court or courts of
competent jurisdiction, which judgment or judgments remain unsatisfied for a
period of 30 days after the right to appeal all such judgments has expired or
otherwise terminated.

SECTION 502.   ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If an Event of Default occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures may, and the Trustee upon request of the Holders of not
less than 25% in principal amount of the Outstanding Debentures shall, declare
the principal of all the Debentures to be due and payable immediately, by notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such entire principal amount and all interest shall become
immediately due and payable. Collection actions or judicial proceedings may be
commenced as set forth in Section 503.


                                          33
<PAGE>

     At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter in this Article provided, the Holders of a majority
in principal amount of the Outstanding Debentures, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:

     (1)  the Company has paid or deposited with the Trustee a sum sufficient to
pay

          (a)  all overdue installments of interest on all Debentures,

          (b)  the principal of (and premium, if any, on) any Debentures which
have become due otherwise than by such declaration of acceleration and interest
thereon at the rate borne by the Debentures,

          (c)  to the extent that payment of such interest is lawful, interest
upon overdue installments of interest at the rate borne by the Debentures, and

          (d)  all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel and the Holders and their agents and counsel if such
Holders have initiated action in accordance with this Section 502; and

     (2)  all Events of Default, other than the non-payment of the principal of
Debentures which have become due solely by such declaration of acceleration,
have been cured or waived as provided in Section 513.

     No such rescission shall affect any subsequent default or impair any right
consequent thereon.

SECTION 503.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

     The Company covenants that if

     (1)  default is made in the payment of any installment of interest on any
Debenture when such interest becomes due and payable and such default continues
for a period of 15 days, or

     (2)  default is made in the payment of the principal of (or premium, if
any, on) any Debenture at its Maturity,

the Company will upon demand of the Trustee or Holders of not less than  25% in
aggregate principal amount of the Outstanding Debentures, pay to the Trustee,
for the benefit of all the Holders of such Debentures, the whole amount then due
and payable on such Debentures for principal, premium, if any, and interest,
with interest upon the overdue principal (and premium,


                                          34
<PAGE>

if any) and, to the extent that payment of such interest shall be legally
enforceable, upon overdue installments of interest, at the rate borne by the
Debentures and, in addition thereto, 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 counsel or the Holders as set forth herein, their agents and counsel, as the
case may be, whether or not judicial proceedings are commenced.

     If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name as trustee of an express trust, or the Holders of not
less than 25% in principal amount of the Debentures Outstanding, on behalf of
all Holders, may institute a judicial proceeding for the collection of the sums
so due and unpaid, may prosecute such proceeding to judgment or final decree and
may enforce the same against the Company or any other obligor upon the
Debentures and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon the Debentures, wherever situated.

     If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Debentureholders by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in the
exercise of any power granted herein, or to enforce any other proper remedy.
Holders of not less than 25% in principal amount of Debentures Outstanding, on
behalf of all Holders, may initiate such appropriate judicial proceedings in the
same manner as the Trustee.  The Trustee or the Holders initiating action
hereunder, as the case may be, shall be reimbursed for the costs of collection
incurred as provided for above in this Section 503.

SECTION 504.   TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Debentures or the property of the Company or of such other obligor, the Trustee
(irrespective of whether the principal of the Debentures shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company for the payment of
overdue principal or interest) shall be entitled and empowered, by intervention
in such proceeding or otherwise,

     (1)  to file and prove a claim for the whole amount of principal, premium,
if any, and interest owing and unpaid in respect of the Debentures and to file
such 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 counsel) and
of the Debentureholders allowed in such judicial proceeding, and

     (2)  to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each


                                          35
<PAGE>

Holder 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 Debentureholders,
to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 607 hereof.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 505.   TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF DEBENTURES.

     All rights of action and claims under this Indenture or the Debentures may
be prosecuted and enforced by the Trustee without the possession of any of the
Debentures or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Debentures in respect of which such judgment has been
recovered.

SECTION 506.   APPLICATION OF MONEY COLLECTED.

     Any money collected by the Trustee or the Holders directly pursuant to this
Article shall be applied in the following order, at the date or dates fixed by
the Trustee and, in case of the distribution of such money on account of
principal or interest, upon presentation of the Debentures and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid.

     FIRST:   to the payment of all amounts due the Trustee under Section 607
hereof;

     SECOND:   to the payment of the amounts then due and unpaid for costs of
collection, principal, premium, if any, and interest on the Debentures in
respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Debentures for principal, premium, if any, and interest,
respectively; and

     THIRD:   to the payment of the remainder, if any, to the Company or any
other person lawfully entitled thereto.

SECTION 507.   LIMITATION ON SUITS.

          (a)  Prior to the declaration of acceleration provided for in Section
502 hereof, no Holder of any Debenture shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

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

     (2)  the Holders of not less than 25% in principal amount of the
Outstanding Debentures shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

     (3)  such Holder or Holders have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

     (4)  the Trustee for 30 days after its receipt of such notice, request and
offer of indemnity has failed to institute any such proceeding; and

     (5)  no direction inconsistent with such written request has been given to
the Trustee during such 30-day period by the Holders of a majority in principal
amount of the Outstanding Debentures;

it being understood and intended that no one or more Debentureholders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Debentureholders, or to obtain or to seek to obtain priority or preference over
any other Debentureholders or to enforce any right under this Indenture, except
in the manner herein provided and for the equal and ratable benefit of all the
Debentureholders.

     (b)  After the declaration of acceleration provided for in Section 502
hereof, Holders of 5% or more in principal amount of Outstanding Debentures may
institute judicial proceedings in respect to such Event of Default which
triggers the declaration of acceleration in their own name in the manner
provided in Section 503 if the Trustee has not instituted such proceedings
within 60 days after such declaration, it being understood that such Holders
shall not have any right in any manner whatever by virtue of, or by availing of,
any provision of the Indenture to affect, disturb or prejudice the rights of any
other Holders of Debentures, or to obtain or to seek to obtain priority or
preference over any other Holders or to enforce any rights under this Indenture,
except in the manner herein provided and for the equal and ratable benefit of
all the Holders of Debentures.

SECTION 508.   UNCONDITIONAL RIGHT OF DEBENTUREHOLDERS TO RECEIVE PRINCIPAL,
PREMIUM AND INTEREST.

     Notwithstanding any other provision in this Indenture, the Holder of any
Debenture shall have the right to receive payment (subject to Section 307) of
the principal of (and premium, if any) and interest on such Debenture on the
Stated Maturity thereof (or, in the case of redemption, on the Redemption Date)
and to institute suit for the enforcement of any such payment, and such rights
shall not be impaired without the consent of such Holder.

SECTION 509.   RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding shall have been
discontinued or abandoned for any reason or shall have 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
Debentureholders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Debentureholders shall continue as though no such proceeding had been
instituted.

SECTION 510.   RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Debentures in the last paragraph of Section
306, no right or remedy herein conferred upon or reserved to the Trustee or to
the Debentureholders is intended to be exclusive of any other right or remedy,
and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

SECTION 511.   DELAY OR OMISSION NOT WAIVER.

     No delay or omission of the Trustee or of any Holder of any Debenture to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article or by law to
the Trustee or to the Debentureholders may be exercised from time to time, and
as often as may be deemed expedient, by the Trustee or by the Debentureholders,
as the case may be.

SECTION 512.   CONTROL BY DEBENTUREHOLDERS.

     The Holders of a majority in principal amount of the Outstanding Debentures
shall have the right to 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 the Trustee, provided that


                                          38
<PAGE>

     (1)  such direction shall not be in conflict with any rule of law or with
this Indenture, and

     (2)  the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction.

SECTION 513.   WAIVER OF PAST DEFAULTS.

     The Holders of not less than a majority in aggregate principal amount of
the Outstanding Debentures may on behalf of the Holders of all the Debentures
waive any past default hereunder and its consequences, provided that a default
in the payment of the principal of, premium, if any, or interest on any
Debenture, or in respect of certain other covenants or provisions hereof cannot
be modified or amended except as set forth in Section 902 hereof.

     Upon any such waiver, such default shall cease to exist and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture, but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

SECTION 514.   UNDERTAKING FOR COSTS.

     All parties to this Indenture agree, and each Holder of any Debenture by
such Holder's acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require 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, suffered or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant.  The
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Debentures,
or to any suit instituted by any Holder for the enforcement of the payment of
the principal of, premium, if any, or interest on any Debenture on or after the
Stated Maturity thereof (or, in the case of redemption, on or after the
Redemption Date).

SECTION 515.   WAIVER OF STAY OR EXTENSION LAWS.

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                END OF ARTICLE FIVE.

                                    THE TRUSTEE

SECTION 601.   CERTAIN DUTIES AND RESPONSIBILITIES.

     (1)  Except during the continuance of an Event of Default,

          (a)  the Trustee undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture, and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

          (b)  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 certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture, but in the case of
any such certificates or opinions which by any provision hereof are specifically
required to be furnished to the Trustee, the Trustee shall be under a duty to
examine the same to determine whether or not they conform to the requirements of
this Indenture.

     (2)  In case 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
such person's own affairs.

     (3)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

          (a)  this Subsection shall not be construed to limit the effect of
Subsection (1) (a) of this Section;

          (b)  the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Trustee
was negligent in ascertaining the pertinent facts;

          (c)  the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the direction of
the Holders of a majority in principal amount of the Outstanding Debentures
relating to the time, method and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred upon
the Trustee, under this Indenture; and

          (d)  no provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for


                                          40
<PAGE>

believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it.

     (4)  Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.

SECTION 602.   NOTICE OF DEFAULTS.

     Within 60 days after the occurrence of any default hereunder, the Trustee
shall transmit by mail to all Debentureholders, as their names and addresses
appear in the Debenture Register, notice of such default hereunder known to a
Responsible Officer of Trustee, unless such default shall have been cured or
waived, provided that (i) except in the case of a default in the payment of the
principal of (or premium, if any) or interest on any Debenture, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the interests of the Debentureholders, and (ii) in the case
of any default of the character specified in Section 501(4), no such notice to
Debentureholders shall be given until at least 30 days after the occurrence
thereof.  For the purpose of this Section, the term "default" means any event
which is, or after notice or lapse of time or both would become, an Event of
Default.

SECTION 603.   CERTAIN RIGHTS OF TRUSTEE.

     Except as otherwise provided in Section 601:

     (1)  the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, note or
other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

     (2)  any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the board of directors of the Company may be sufficiently evidenced by a
Company Resolution;

     (3)  whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

     (4)  the Trustee may consult with counsel (who may be counsel to the
Company) and the advice of such counsel or any Opinion of Counsel shall be full
and complete authorization and protection in respect of any action taken,
suffered or omitted by it hereunder in good faith and in reliance thereon;


                                          41
<PAGE>

     (5)  the Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request or direction of any of
the Debentureholders pursuant to this indenture, unless such Debentureholders
shall have offered to the Trustee reasonable indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such
request or direction;

     (6)  prior to the occurrence of an Event of Default hereunder and after the
curing of all Events of Default, the Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent,
order, bond, debenture, note or other paper or document unless requested to do
so by the Holders of not less than a majority in aggregate principal amount of
the Debentures then outstanding, but the Trustee, in its discretion, may make
such further inquiry or investigation into such facts or matters as it may see
fit, and, provided that if the payment within a reasonable time to the Trustee
of the costs, expenses and liabilities likely to be incurred in the making of
such investigation is not, in the opinion of the Trustee, reasonably assured to
the Trustee by the terms of this Indenture, the Trustee may require reasonable
indemnity against such expense or liability as a condition to so proceeding; and

     (7)  the Trustee shall have no duty to inquire as to the performance of the
Company's covenants in Article Ten.  In addition, the Trustee shall not be
deemed to have knowledge of any Default or Event of Default, except (i) any
Default or Event of Default occurring pursuant to Section 501(1), 501(2) or
1001, or (ii) any Default or Event of Default of which the Trustee shall have
received written notification or obtained actual knowledge.

SECTION 604.   NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF DEBENTURES.

     The recitals contained herein and in the Debentures, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company
and the Trustee assumes no responsibility for their correctness.  The Trustee
makes no representations as to the validity or sufficiency of this Indenture or
of the Debentures.  The Trustee shall not be accountable for the use or
application by the Company of Debentures or the proceeds thereof.

SECTION 605.   TRUSTEE MAY HOLD DEBENTURES.

     The Trustee, any Authenticating Agent, any Paying Agent, any Debenture
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Debentures and, subject to Section
612, may otherwise deal with the Company with the same rights it would have it
if were not Trustee, Authenticating Agent, Paying Agent, Debenture Registrar or
such other agent.

SECTION 606.   MONEY HELD IN TRUST.

     Money held by the Trustee in trust hereunder need not be segregated from

liability for interest on any money received by it hereunder except as otherwise
agreed in writing with the Company.

SECTION 607.   COMPENSATION AND REIMBURSEMENT.

     The Company agrees

     (1)  to pay to the Trustee from time to time reasonable compensation for
all services rendered by it hereunder (which compensation shall not be limited

trust);

     (2)  except as otherwise expressly provided for herein, to reimburse the
Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this
Indenture (including the reasonable compensation and the expenses and
disbursements of its agents and counsel), except any such expense, disbursement
or advance as may be attributable to its negligence or bad faith; and

     (3)  to indemnify the Trustee for, and to hold it harmless against, any
loss, liability or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of this
trust, including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder.

this Section, the Trustee shall have a lien prior to the Debentures upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of, premium, if any or interest on
Debentures.

SECTION 608.   DISQUALIFICATION; CONFLICTING INTERESTS.

     (1)  If the Trustee has or shall acquire any conflicting interest, as
defined in this Section 608, then, within 90 days after ascertaining that it has
such conflicting interest, and if the default (as defined in Section 608(3)) to
which such conflicting interest relates has not been cured or duly waived or
otherwise eliminated before the end of such 90-day period, the Trustee shall
either eliminate such conflicting interest or resign in the manner and with the
effect hereinafter specified in this Article.

     (2)  In the event that the Trustee shall fail to comply with the provisions
of Subsection (1) of this Section, within ten (10) days after the expiration of
such 90-day period, the Trustee shall transmit by mail to all Debentureholders,
as their names and addresses appear in the Debenture Register, notice of such
failure.


                                          43
<PAGE>

     (3)  For the purposes of this Section, the Trustee shall be deemed to have
a conflicting interest if:

          (a)  the Trustee is trustee under another indenture under which any
other securities, or certificates of interest or participation in any other
securities, of the Company are outstanding, unless such other indenture is a
collateral trust indenture under which the only collateral consists of
Debentures issued under this Indenture, provided that there shall be excluded
from the operation of this paragraph any indenture or indentures under which
other securities, or certificates of interest or participation in other
securities, of the Company are outstanding, if

               (i)  this Indenture and such other indenture or indentures are
wholly unsecured and such other indenture or indentures are hereafter qualified
under the Trust Indenture Act, unless the Commission shall have found and
declared by order pursuant to Section 306(b) or Section 307(1) of the Trust
Indenture Act that differences exist between the provisions of this Indenture
and the provisions of such other indenture or indentures which are so likely to
involve a material conflict of interest as to make it necessary in the public
interest or for the protection of investors to disqualify the Trustee from
acting as such under this Indenture and such other indenture or indentures, or

               (ii) the Company shall have sustained the burden of proving, on
application to the Commission and after opportunity for hearing thereon, that
trusteeship under this Indenture and such other indenture or indentures is not
so likely to involve a material conflict of interest as to make it necessary in
the public interest or for the protection of investors to disqualify the Trustee
from acting as such under one of such indentures;

          (b)  the Trustee or any of its directors or executive officers is an
underwriter for the Company;

          (c)  the Trustee directly or indirectly controls or is directly or
indirectly controlled by or is under direct or indirect common control with an
underwriter for the Company;

          (d)  the Trustee or any of its directors or executive officers is a
director, officer, partner, employee, appointee or representative of the
Company, or of an underwriter (other than the Trustee itself) for the Company
who is currently engaged in the business of underwriting, except that the
Trustee may be designated by the Company or by any underwriter for the Company
to act in the capacity of transfer agent, registrar, custodian, paying agent,
fiscal agent, escrow agent or depositary, or in any other similar capacity or,
subject to the provisions of paragraph (a) of this Subsection, to act as
trustee, whether under an indenture or otherwise;

          (e)  10% or more of the voting securities of the Trustee is
beneficially owned either by the Company or by any director or executive officer
thereof, or 20% or more of such voting securities is beneficially owned,
collectively, by any two or more of such persons; or 10% or more of the voting
securities of the Trustee is beneficially owned either by an underwriter for


                                          44
<PAGE>

the Company or by any director, partner or executive officer of any such
underwriter, or is beneficially owned, collectively, by any two or more such
persons;

          (f)  the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default (as hereinafter in this
Subsection defined), (i) 5% or more of the voting securities, or 10% or more of
any other class of security of the Company not including the Debentures issued
under this Indenture and securities issued under any other indenture under which
the Trustee is also trustee, or (ii) 10% or more of any class of security of an
underwriter for the Company;

          (g)  the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default (as hereinafter in this
Subsection defined), 5% or more of the voting securities of any person who, to
the knowledge of the Trustee, owns 10% or more of the voting securities of, or
controls directly or indirectly or is under direct or indirect common control
with, the Company;

          (h)  the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default (as hereinafter in this
Subsection defined), 10% or more of a class of security of any person who, to
the knowledge of the Trustee, owns 50% or more of the voting securities of the
Company;

          (i)  the Trustee owns, on the date of default upon the Debentures or
on any anniversary of such default while the default upon the Debentures remains
outstanding, in the capacity of executor, administrator, testamentary or inter
vivos trustee, guardian, committee or conservator, or in any other similar
capacity, an aggregate of 25% or more of the voting securities, or of any class
of security, of any person, the beneficial ownership of a specified percentage
of which would have constituted a conflicting interest under paragraph (f), (g)
or (h) of this Subsection.  As to any such securities of which the Trustee
acquired ownership through becoming executor, administrator or testamentary
trustee of an estate which included them, the provisions of the preceding
sentence shall not apply, for a period of two years from the date of such
acquisition, to the extent that such securities included in such estate do not
exceed 25% of such voting securities or 25% of any such class of security.
Promptly after the date of any such default and annually each succeeding year
that the Debentures remain in default, the Trustee shall make a check of its
holdings of such securities in any of the above-mentioned capacities as of such
dates.  If the Company fails to make payment in full of the principal of (or
premium, if any) or interest on any of the Debentures when and as the same
becomes due and payable, and such failure continues for 30 days thereafter, the
Trustee shall make a prompt check of its holdings of such securities in any of
the above-mentioned capacities as of the date of the expiration of such 30-day
period, and after such date, notwithstanding the foregoing provisions of this
paragraph, all such securities so held by the Trustee, with sole or joint
control over such securities vested in it, shall, but only so long as such
failure shall continue, be considered as though beneficially owned by the
Trustee for the purposes of paragraphs (f), (g) and (h) of this Subsection; or


                                          45
<PAGE>

          (j)  except under the circumstances described in paragraphs (1), (3),
(4), (5) or (6) of Section 311(b) of the Trust Indenture Act, the Trustee shall
be or become a creditor of the Company.

     The specification of percentages in paragraphs (e) to (i), inclusive, of
this Subsection shall not be construed as indicating that the ownership of such
percentage of the securities of a person is or is not necessary or sufficient to
constitute direct or indirect control for the purposes of paragraph (c) or (g)
of this Subsection.

     For the purposes of paragraphs (f), (g), (h) and (i) of this Subsection
only, (i) the terms "security" and "securities" shall include only such

any note or other evidence of indebtedness issued to evidence an obligation to
repay moneys lent to a person by one or more banks, trust companies or banking
firms, or any certificate of interest or participation in any such note or
evidence of indebtedness; (ii) an obligation shall be deemed to be "in default"
when a default in payment of principal shall have continued for 30 days or more
and shall not have been cured; and (iii) the Trustee shall not be deemed to be
the owner or holder of (A) any security which it holds as collateral security,
as trustee or otherwise, for an obligation which is not in default as defined in
clause (ii) above, or (B) any security which it holds as collateral security
under this Indenture, irrespective of any default hereunder, or (C) any security
which it holds as agent for collection, or as custodian, escrow agent or
depositary, or in any similar representative capacity.

     (4)  For the purposes of this Section:

          (a)  The term "underwriter," when used with reference to the Company
means every person who, within one year prior to the time as of which the
determination is made, has purchased from the Company with a view to, or has
offered or sold for the Company in connection with, the distribution of any
security of the Company outstanding at such time, or has participated or has had
a direct or indirect participation in any such undertaking, or has participated
or has had a participation in the direct or indirect underwriting of any such
undertaking, but such term shall not include a person whose interest was limited
to a commission from an underwriter or dealer not in excess of the usual and
customary distributors' or sellers' commission.

          (b)  The term "director" means any director of a corporation or any

affairs of a person, or any


                                          46
<PAGE>

security issued under or pursuant to any trust, agreement or arrangement whereby
a trustee or trustees or agent or agents for the owner or holder of such
security are presently entitled to vote in the direction or management of the

which with notice or passage of time, or both, would constitute an Event of
Default.

          (a)  A specified percentage of the voting securities of the Trustee,
the Company or any other person referred to in this Section (each of whom is
referred to as a "person" in this paragraph) means such amount of the
outstanding voting securities of such person as entitles the holder or holders
thereof to cast such specified percentage of the aggregate votes which the

cast in the direction or management of the affairs of such person.

          (b)  A specified percentage of a class of securities of a person means
such percentage of the aggregate amount of securities of the class outstanding.

otherwise;

an obligation of the issuer not in default as to principal or interest or
otherwise; and

<PAGE>

               (iv)   securities held in escrow if placed in escrow by the
issuer thereof, provided, that any voting securities of an issuer shall be
deemed outstanding if any person other than the issuer is entitled to exercise
the voting rights thereof.

          (e)  A security shall be deemed to be of the same class as another
security if both securities confer upon the holder or holders thereof
substantially the same rights and privileges, provided, that, in the case of
secured evidences of indebtedness, all of which are issued under a single
indenture, differences in the interest rates or maturity dates of various series
thereof shall not be deemed sufficient to constitute such series different
classes and provided, further, that, in the case of unsecured evidences of
indebtedness, differences in the interest rates or maturity dates thereof shall
not be deemed sufficient to constitute them securities of different classes,
whether or not they are issued under a single indenture.

condition so published.  If at any time the Trustee shall cease to be eligible
in accordance with the provisions of this Section, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article.

SECTION 610.   RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 611.

     (2)  The Trustee may resign at any time by giving written notice thereof to
the Company.  If an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after the giving of such

jurisdiction for the appointment of a successor Trustee.  Such court may
thereupon after such notice, if any, as it may deem proper and prescribe, remove
the Trustee and appoint a successor Trustee.

     (3)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Debentures, delivered to the
Trustee and to the Company.  If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 30 days after the
giving of such notice of removal, the Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.


                                          48

     (4)  If at any time:

          (a)  the Trustee shall fail to comply with Section 608(1) after
written request therefor by the Company or by any Holder who has been a bona
fide Holder of a Debenture for at least six months, or

          (b)  the Trustee shall cease to be eligible under Section 609 and
shall fail to resign after written request therefor by the Company or by any
Holder who has been a bona fide Holder of a Debenture for at least six months,
or

          (c)  the Trustee shall become incapable of acting or shall be adjudged
a bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, THEN, in any such case, (i) the Company by a Company Resolution may
remove the Trustee, or (ii) subject to Section 514, any Holder who has been a
bona fide Holder of a Debenture for at least six months, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee.

     (5)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company,
by a Company Resolution, shall promptly appoint a successor Trustee.  If, within
one year after such resignation, removal or incapability, or the occurrence of
such vacancy, a successor Trustee shall be appointed by Act of the Holders of a
majority in principal amount of the Outstanding Debentures delivered to the
Company and the retiring Trustee, the successor Trustee so appointed, forthwith
upon its acceptance of such appointment, shall become the successor Trustee and
supersede the successor Trustee appointed by the Company.  If no successor
Trustee shall have been so appointed by the Company or the Debentureholders and
accepted appointment in the manner hereinafter provided, any Holder who has been
a bona fide holder of a Debenture for at least six months, on behalf of himself
and all others similarly situated, may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

     (6)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee by mailing written
notice of such event by first-class mail, postage prepaid, to all
Debentureholders as their names and addresses appear in the Debenture Register.
Each notice shall include the name of the successor Trustee and the address of
its Corporate Trust Office.

SECTION 611.   ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     Every successor Trustee appointed hereunder shall execute, acknowledge and
deliver to the Company and to the retiring Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the retiring Trustee
shall become effective and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the


                                          49
<PAGE>

rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring Trustee, upon payment of its
charges, shall execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder, subject nevertheless to its lien, if
any, provided for in Section 607. Upon request of any such successor Trustee,
the Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts.

     No successor Trustee shall accept its appointment unless at the time of
such acceptance such Successor Trustee shall be qualified and eligible under
this Article.

SECTION 612.   MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided that
such corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  In case any Debentures shall have been authenticated
but not delivered by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Debentures so authenticated with the same effect
as if such successor Trustee had itself authenticated such Debentures.

SECTION 613.   PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     (1)  Subject to Subsection (2) of this Section, if the Trustee shall be or
shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within three months prior to a default, as defined in Subsection (3) of
this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Debentures and the holders of other indenture securities, as defined in
Subsection (3) of this Section:

          (a)  an amount equal to any and all reductions in the amount due and
owing upon any claim as such creditor in respect of principal or interest,
effected after the beginning of such three-month period and valid as against the
Company and its other creditors, except any such reduction resulting from the
receipt or disposition of any property described in paragraph (2) of this
Subsection, or from the exercise of any right of set off which the Trustee could
have exercised if a petition in bankruptcy had been filed by or against the
Company upon the date of such default; and

          (b)  all property received by the Trustee in respect of any claims as
such creditor, either as security therefor, or in satisfaction or composition
thereof or otherwise, after the beginning of such three-month period, or an
amount equal to the proceeds of any such


                                          50
<PAGE>

property if disposed of, subject, however, to the rights, if any, of the Company
and its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee:

               (i)    to retain for its own account (A) payments made on
account of any such claim by any Person (other than the Company) who is liable
thereon, (B) the proceeds of the bona fide sale of any such claim by the Trustee
to a third Person, and (C) distributions made in cash, securities or other
property in respect of claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law;

               (ii)   to realize for its own account upon any property held by
it as security for any such claim, if such property was so held prior to the
beginning of such three-month period;

               (iii)  to realize for its own account but only to the extent of
the claim hereinafter mentioned, upon any property held by it as security for
any such claim, if such claim was created after the beginning of such three-
month period and such property was received as security therefor simultaneously
with the creation thereof, and if the Trustee shall sustain the burden of
proving that at the time such property was so received the Trustee had no
reasonable cause to believe that a default, as defined in Subsection (3) of this
Section, would occur within three months; or

               (iv)   to receive payment on any claim referred to in paragraph
(ii) or (iii), against the release of any property held as security for such
claim as provided in paragraph (ii) or (iii), as the case may be, to the extent
of the fair value of such property.

     For the purposes of paragraphs (ii), (iii) and (iv), property substituted
after the beginning of such three-month period for property held as security at
the time of such substitution, to the extent of the fair value of the property
released, shall have the same status as the property released and, to the extent
that any claim referred to in any of such paragraphs is created in renewal of or
in substitution for or for the purpose of repaying or refunding any preexisting
claim of the Trustee as such creditor, such claim shall have the same status as
such pre-existing claim.

     If the Trustee shall be required to account, the funds and property held in
such special account and the proceeds thereof shall be apportioned among the
Trustee, the Debentureholders and the holders of other indenture securities in
such manner that the Trustee, the Debentureholders and the holders of other
indenture securities realize, as a result of payments from such special account
and payments of dividends on claims filed against the Company in bankruptcy or
receivership or in proceedings for reorganization pursuant to the Federal
Bankruptcy Act or applicable State law, the same percentage of their respective
claims, figured before crediting to the claim of the Trustee anything on account
of the receipt by it from the Company of the funds and property in such special
account and before crediting to the respective claims of the Trustee and the
Debentureholders and the holders of other indenture securities


                                          51
<PAGE>

dividends on claims filed against the Company in bankruptcy or receivership or
in proceedings for reorganization pursuant to the Federal Bankruptcy Act or
applicable State law, but after crediting thereon receipts on account of the
indebtedness represented by their respective claims from all sources other than
from such dividends and from the funds and property so held in such special
account.  As used in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such claim, in
bankruptcy or receivership or proceedings for reorganization pursuant to the
Federal Bankruptcy Act or applicable State law, whether such distribution is
made in cash, securities or other property, but shall not include any such
distribution with respect to the secured portion, if any, of such claim.  The
court in which such bankruptcy, receivership or proceedings for reorganization
is pending shall have jurisdiction (i) to apportion among the Trustee, the
Debentureholders and the holders of other indenture securities, in accordance
with the provisions of this paragraph, the funds and property held in such
special account and proceeds thereof, or (ii) in lieu of such apportionment, in
whole or in part, to give to the provisions of this paragraph due consideration
in determining the fairness of the distributions to be made to the Trustee and
the Debentureholders and the holders of other indenture securities with respect
to their respective claims, in which event it shall not be necessary to
liquidate or to appraise the value of any securities or other property held in
such special account or as security for any such claim, or to make a specific
allocation of such distributions as between the secured and unsecured portions
of such claims, or otherwise to apply the provisions of this paragraph as a
mathematical formula.

     Any Trustee which has resigned or been removed after the beginning of such
three-month period shall be subject to the provisions of this Subsection as
though such resignation or removal had not occurred.  If any Trustee has
resigned or been removed prior to the beginning of such three-month period, it
shall be subject to the provisions of this Subsection if and only if the
following conditions exist: (i) the receipt of property or reduction of claim,
which would have given rise to the obligation to account, if such Trustee had
continued as Trustee, occurred after the beginning of such three-month period;
and (ii) such receipt of property or reduction of claim occurred within three
months after such resignation or removal.

     (2)  There shall be excluded from the operation of subsection (a) of this
Section a creditor relationship arising from:

          (a)  the ownership or acquisition of securities issued under any
indenture, or any security or securities having a maturity of one year or more
at the time of acquisition by the Trustee;

          (b)  advances authorized by a receivership or bankruptcy court of
competent jurisdiction or by this Indenture for the purpose of preserving any
property which shall at any time be subject to the lien of this Indenture or of
discharging tax liens or other prior liens or encumbrances thereon, if notice of
such advances and of the circumstances surrounding the making thereof is given
to the Debentureholders at the time and in the manner provided in this
Indenture;


                                          52
<PAGE>

          (c)  disbursements made in the ordinary course of business in the
capacity of trustee under an indenture, transfer agent, registrar, custodian,
paying agent, fiscal agent or depositary, or other similar capacity;

          (d)  an indebtedness created as a result of services rendered or
premises rented; or an indebtedness created as a result of goods or securities
sold in a cash transaction, as defined in Subsection (3) of this Section;

          (e)  the ownership of stock or other securities of a corporation
organized under the provisions of Section 25(a) of the Federal Reserve Act, as
amended, which is directly or indirectly a creditor of the Company; and

          (f)  the acquisition, ownership, acceptance or negotiation of any
drafts, bills of exchange, acceptances or obligations which fall within the
classification of self-liquidating paper, as defined in Subsection (3) of this
Section.

     (3)  For the purposes of this Section only:

          (a)  the term "default" means any failure to make payment in full of
the principal of or interest on any of the Debentures or upon the other
indenture securities when and as such principal or interest become due and
payable;

          (b)  the term "other indenture securities" means securities upon which
the Company is an obligor outstanding under any other indenture (i) under which
the Trustee is also trustee, (ii) which contains provisions substantially
similar to the provisions of this Section, and (iii) under which a default
exists at the time of the apportionment of the funds and property held in such
special account;

          (c)  the term "cash transaction" means any transaction in which full
payment for goods or securities sold is made within seven days after delivery of
the goods or securities in currency or in checks or other orders drawn upon
banks or bankers and payable upon demand;

          (d)  the term "self-liquidating paper" means any draft, bill of
exchange, acceptance or obligation which is made, drawn, negotiated or incurred
by the Company for the purpose of financing the purchase, processing,
manufacturing, shipment, storage or sale of goods, wares or merchandise and
which is secured by documents evidencing title to, possession of, or a lien
upon, the goods, wares or merchandise or the receivables or proceeds arising
from the sale of the goods, wares or merchandise previously constituting the
security, provided the security is received by the Trustee simultaneously with
the creation of the creditor relationship with the Company arising from the
making, drawing, negotiating or incurring of the draft, bill of exchange,
acceptance or obligation;

          (e)  the term "Company" means any obligor upon the Debentures; and


                                          53
<PAGE>

          (f)  the term "Federal Bankruptcy Act" means the Bankruptcy Act or
Title II of the United States Code.

SECTION 614.   APPOINTMENT OF AUTHENTICATING AGENT.

     At any time when any of the Debentures remain Outstanding, the Trustee may
appoint an Authenticating Agent or Agents which shall be authorized to act on
behalf of the Trustee to authenticate Debentures issued upon original issuance,
exchange, registration of transfer or partial redemption thereof or pursuant to
Section 307, and Debentures so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Wherever reference is made in this
Indenture to the authentication and delivery of Debentures by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $10,000,000 and
subject to supervision or examination by Federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of such supervising or examining authority, for
the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Debentureholders
as their names and addresses appear in the Debenture Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like


                                          54
<PAGE>

effect as if originally named as an Authenticating Agent herein.  No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

     The Trustee agrees to pay to each Authenticating Agent from time to time
reasonable compensation for its services under this Section, and the Trustee
shall be entitled to be reimbursed for such payments, subject to the provisions
of Section 607.

     If an appointment is made pursuant to this Section, the Debentures may have
endorsed thereon, in lieu of the form of certificate of authentication set forth
in Section 204, a certificate of authentication in the following form:


                                          55

Indenture."

             DEBENTUREHOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

SECTION 701.   COMPANY TO FURNISH TRUSTEE NAMES AND ADDRESSES OF
DEBENTUREHOLDERS.

     The Company will furnish or cause to be furnished to the Trustee, if not
already provided to the Trustee:

     (1)  quarterly, not later than first day of the month in which an Interest
Payment Date occurs, a list, in such form as the Trustee may reasonably require,
of the names and addresses of the Debentureholders as of such Regular Record
Date, and

     (2)  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 fifteen (15) days prior to the time
such list is furnished;

provided, however, that such list need not be furnished so long as the Trustee
is the Debenture Registrar.

     The Trustee shall furnish, and the Company shall cause the Trustee to
furnish, to Miller & Schroeder Financial, Inc. or its successor ("Miller &
Schroeder") at such times as Miller & Schroeder may reasonably request in
writing, within 30 days of the receipt by the Trustee of such request, a list of
the names and addresses of the Debentureholders as of a date not more than 15
days prior to the time such list is furnished.

SECTION 702.   PRESERVATION OF INFORMATION; COMMUNICATIONS TO DEBENTUREHOLDERS.

     (1)  The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Debentureholders contained in the most
recent list furnished to the Trustee as provided in Section 701 and the names
and addresses of Debentureholders received by the Trustee in its capacity as
Debenture Registrar. The Trustee may destroy any list furnished to it as
provided in Section 701 upon receipt of a new list so furnished.

     (2)  If three or more Debentureholders (herein referred to as "applicants")
apply in writing to the Trustee, and furnish to the Trustee reasonable proof
that each such applicant has owned a Debenture for a period of at least six
months preceding the date of such application, and such application states that
the applicants desire to communicate with other Debentureholders with respect to
their rights under this Indenture or under the Debentures and is accompanied by
a copy of the form of proxy or other communication which such applicants propose
to transmit, then the Trustee shall, within five business days after the receipt
of such application, at its election, either


                                          57
<PAGE>

          (a)  afford such applicants access to the information preserved at the
time by the Trustee in accordance with Section 702(1), or

          (b)  inform such applicants as to the approximate number of
Debentureholders whose names and addresses appear in the information preserved
at the time by the Trustee in accordance with Section 702(1) and as to the
approximate cost of mailing to such Debentureholders the form of proxy or other
communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder whose name and address appears in the information preserved
at the time by the Trustee in accordance with Section 702(1) a copy of the form
of proxy or other communication which is specified in such request, with
reasonable promptness after a tender to the Trustee of the material to be mailed
and of payment, or provision for the payment, of the reasonable expenses of
mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the
Debentureholders or would be in violation of applicable law.  Such written
statement shall specify the basis of such opinion.  If the Commission, after
opportunity for a hearing upon the objections specified in the written statement
so filed and, on notice to the Trustee, shall enter an order refusing to sustain
any of such objections or if, after the entry of an order sustaining one or more
of such objections, the Commission shall find, after notice and opportunity for
hearing, that all the objections so sustained have been met and shall enter an
order so declaring, the Trustee shall mail copies of such material to all such
Debentureholders with reasonable promptness after the entry of such order and
the renewal by such applicants of their applications.

     (3)  Every Holder of Debentures, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the
Debentureholders in accordance with Section 702(2), regardless of the source
from which such information was derived, and that the Trustee shall not be held
accountable by reason of mailing any material pursuant to a request made under
Section 702(2).

SECTION 703.   REPORTS BY THE COMPANY.

     The Company shall:

     (1)  File with the Trustee, within 15 days after the Company is required to
file the same with the Commission or to mail the same to its shareholders,
copies of the quarterly reports, annual reports and the information, documents
and other reports (or copies of such portions of the foregoing as the Commission
may from time to time by rules and regulations prescribe) which the Company may
be required to file with the Commission pursuant to Section 12 or 13 or Section
15(d) of the Securities Exchange Act of 1934, as amended (the "1934 Act"), or to
mail to its shareholders pursuant to Section 14(a) thereof.  The Company agrees
to make all


                                          58
<PAGE>

filings with the Commission required by Section 15(d) of the 1934 Act without
regard to the number of holders of record of the Debentures.

     (2)  File with the Trustee and the Commission, in accordance with rules and
regulations prescribed from time to time by the Commission, such additional
information, documents and reports with respect to compliance by the Company
with the conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations.

     (3)  Within 15 days after the date on which the Company is required to file
reports with the Commission under the 1934 Act, or within 15 days after such
date would have occurred had the Company been required to file reports under the
1934 Act, the Company shall transmit copies of such reports by mail to all
Debentureholders, as their names and addresses appear on the Debenture Register,
without cost to such Debentureholders.

     (4)  Transmit by mail to all Debentureholders, as their names and addresses
appear in the Debenture Register, within 30 days after the filing thereof with
the Trustee (unless some other time shall be fixed by the Commission) (a) any
annual report filed with the Trustee pursuant to paragraph (1) of this Section;
(b) summaries, including a balance sheet and income statement, of the quarterly
reports filed with the Trustee pursuant to paragraph (1) of this Section,
provided, however, that, if requested by a Debentureholder, the Company shall
transmit to such Debentureholder, within 15 days after such request, a copy of
the Company's quarterly report as filed with the Commission; and (c) any other
information, documents or reports required to be filed by the Company pursuant
to paragraphs (1) and (2) of this Section as may be required by rules and
regulations prescribed from time to time by the Commission.

     (5)  File with the Trustee within 45 days after the end of each of the
Company's fiscal quarters a certificate of the Chief Executive Officer and the
Controller of the Company stating that the Company is in compliance with Article
Ten, setting forth the calculations supporting such certification, where
applicable, and attaching the unaudited financial statements of the Company, and
file a supplemental certificate to the same effect attaching the audited
financial statements of the Company promptly after such statements become
available.

     (6)  File with the Trustee, within 90 days after the end of each fiscal
year of the Company ending after the date hereof, a certificate of the Chief
Executive Officer and Controller of the Company as to such person's knowledge of
the Company's compliance with all conditions and covenants under this Indenture,
such compliance to be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

     (1)  Within sixty (60) days of May 15 each year commencing with the year
1998, the Trustee shall transmit by mail to all Debentureholders, as hereafter
provided for, a brief report with respect to the following, provided that no

SECTION 801.   COMPANY MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS.

     The Company shall not consolidate with or merge into any other Person or
convey, transfer or lease its properties and assets substantially as an entirety
to any Person, and the Company shall not permit any Person to consolidate with
or merge into the Company or any Subsidiary or convey, transfer or lease its
properties and assets substantially as an entirety to the Company or any
Subsidiary, unless:

     (1)  in case the Company shall consolidate with or merge into another
corporation, trust or entity, the Person formed by such consolidation or into
which the Company is merged shall be a trust, corporation or other entity
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 an indenture
supplemental hereto, executed and delivered to the Trustee, in form satisfactory
to the Trustee and counsel to the Trustee, the due and punctual payment of the
principal of (and premium, if any) and interest on all the Debentures and the
performance of every covenant of this Indenture on the part of the Company to be
performed or observed;

     (2)  immediately after giving effect to such transaction, and treating any
indebtedness which becomes an obligation of the Company or a Subsidiary as a
result of such transaction as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default, and no event
which, with the passage of time or the giving of notice, would become an Event
of Default, shall have occurred and be continuing;

     (3)  the Company, or the surviving entity, as the case may be, immediately
before and immediately after giving effect to such transaction or series of
transactions (including, without limitation, any Indebtedness incurred or
anticipated to be incurred in connection with or in respect of such transaction
or series of transactions) shall have an Adjusted Consolidated Tangible Net
Worth equal to or greater than the amount required by Section 1011 hereof;

     (4)  the Company, or the surviving entity, as the case may be, immediately

connection with or in respect of such transaction or series of transactions)
shall have an Adjusted Consolidated Tangible Net Worth equal to or greater than
the Company's Adjusted Consolidated Tangible Net Worth immediately before giving
effect to such transaction or series of transactions;

     (5)  in case the Company shall consolidate with or merge into United
Development Management Company, an Illinois corporation (together with any
successor or assign, the "Corporate Parent") or the Corporate Parent shall merge
into the Company, all Indebtedness of the Corporate Parent incurred in
connection with or in respect of the transaction, shall be subordinated to

however (i) if an Event of Default occurs and notice is provided to the Company
pursuant to Section 502, or (ii) the Company fails to make any payment of
principal or interest in a timely manner, without giving effect to any cure
periods or notice requirements, or (iii) if the Company breaches the covenants
contained in Section 1011, the Company shall not make any payment of principal,
interest or any other payment in any other form, on such Indebtedness, until

been made; and (iv) upon the occurrence of any bankruptcy, reorganization or
similar proceedings, the Company shall not make any payment of principal,
interest or any other payment in any form on such Indebtedness, nor shall any

occurrence of any bankruptcy, reorganization, or similar proceeding, the
Debentures will be paid in full before any further payments are made on such
Indebtedness.  The Corporate Parent covenants and agrees that it will notify
every Affiliate of the Company's agreement under this Section 801(5), and the
Corporate Parent shall obtain an agreement from every Affiliate or other person
loaning money to Corporate Parent for the Benefit of Affiliates, to the effect
that such Affiliate or person agrees, upon the occurrence of a bankruptcy,
reorganization or similar event, that the Affiliate or person shall be
prohibited from receiving any payment with respect to any Indebtedness, whether
principal or interest, until the Debentures shall have been indefensibly paid in
full, in the form and substance satisfactory to the Trustee and counsel to the
Trustee;

transactions, the Company or the surviving entity, as the case may be, could
incur $1.00 of Indebtedness pursuant to paragraph (3) of Section 1007 hereof;
and

     (7)  the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that such consolidation, merger, conveyance,
transfer or lease and, if a supplemental indenture is required in connection
with such transaction, such supplemental indenture comply with this Article and
that all conditions precedent herein provided for relating to such transaction
have been complied with.

SECTION 802.   SUCCESSOR SUBSTITUTED.

     Upon any consolidation or merger of the Company with or into any other
corporation, trust or other entity in accordance with Section 801, the successor
Person formed by such consolidation or into which the Company is merged 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
Person had been named as the Company herein, and thereafter the predecessor
Person shall be relieved of all obligations and covenants under this Indenture
and the Debentures.

<PAGE>

institute suit for the enforcement of any such payment on or after the Stated

     (2)  reduce the percentages in principal amount of the Outstanding
Debentures, the consent of whose Debentureholders is required for any such
supplemental indenture, or the consent of whose Debentureholders is required for

defaults hereunder and their consequences) provided for in this Indenture, or

     (3)  modify any of the provisions of this Section, Section 513, or Section
1012, except to increase any such percentage or to provide that certain other
provisions of this Indenture cannot be modified or waived without the consent of
the Holder of each Outstanding Debenture affected thereby.

     It shall not be necessary for any Act of Debentureholders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

SECTION 903.   EXECUTION OF SUPPLEMENTAL INDENTURES.

     In executing, or accepting the additional trusts created by, any

SECTION 1001.  PAYMENT OF PRINCIPAL AND INTEREST.

     The Company will duly and punctually pay the principal of, premium, if any,
and interest on the Debentures in accordance with the terms of the Debentures
and this Indenture.

SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in Minneapolis, Minnesota, an office or agency
where Debentures may be presented or surrendered for payment, where Debentures
may be surrendered for registration of transfer or exchange, and where notices
and demands to or upon the Company in respect of the Debentures and this
Indenture may be served.  The Company will give prompt written notice to the
Trustee of the location and any change in the location, of such office or
agency.  Until otherwise designated by the Company in a written notice to the
Trustee, and if at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee its agent to receive such presentations, surrenders, notices and
demands.

     The Company may also from time to time designate one or more other offices
or agencies where the Debentures may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations, provided that
no such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in Minneapolis, Minnesota, for such
purposes.  The Company will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

     The Company hereby initially designates the Corporate Trust Office of the
Trustee set forth in the first paragraph of this instrument as an agency of the
Company.

SECTION 1003.  MONEY FOR DEBENTURE PAYMENTS TO BE HELD IN TRUST.

     If the Company shall at any time act as its own Paying Agent, it will, on
or before each due date of the principal of (and premium, if any) or interest on
any of the Debentures, segregate and hold in trust for the benefit of the
persons entitled thereto a sum sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action.

     Whenever the Company shall have one or more Paying Agents, on or prior to
each due date of the principal of (and premium, if any) or interest on any
Debentures, it will deposit with a


                                          67
<PAGE>

Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal (and premium, if any) or interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

     The Company will cause each Paying Agent other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree
with the Trustee, subject to the provisions of this Section, that such Paying
Agent will:

     (1)  hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Debentures in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided;

     (2)  give the Trustee notice of any default by the Company (or any other
obligor upon the Debentures) in the making of any payment of principal (and
premium, if any) or interest on the Debentures; and

     (3)  at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent.  Upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

     Unless otherwise required by applicable law, any money deposited with the
Trustee or any Paying Agent, or then held by the Company, in trust for the
payment of the principal of (and premium, if any) or interest on any Debenture
and remaining unclaimed for two years after such principal (and premium, if any)
or interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust.
The Holder of such Debenture shall thereafter, as an unsecured general creditor,
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease, provided that the Trustee or
such Paying Agent, before being required to make any such repayment, at the
expense of the Company, may cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of
general circulation in Minneapolis, Minnesota, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
thirty (30) days from the date of such publication, any unclaimed balance of
such money then remaining will be repaid to the Company.

all things necessary to preserve and keep in full force and effect the corporate
existence of the Company and each Subsidiary, and all material rights,
certificates, authorities, licenses, permits and approvals of any of them, and
shall conduct its business in conformity with the requirements of such rights,
certificates, authorities, licenses, permits and approvals, provided that the
Company shall not be required to preserve any such right, certificate,
authority, license or permit if the Board of Directors of the Company shall
reasonably and in good faith determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company or of its
Subsidiaries and that the loss thereof is not disadvantageous in any material
respect to the Debentureholders.  The Company shall not change (and the Company
shall not allow any Subsidiary to change) its fundamental line of business from
land development and the design, construction and sale of homes to any other
line of business.

SECTION 1005.  PAYMENT OF TAXES AND ASSESSMENTS.

Company or any Subsidiary before the same shall be in default, as well as all
lawful claims for labor, materials and supplies which, if unpaid, might become a
lien or charge upon such property or any part thereof, provided that the Company
or any Subsidiary shall not be required to cause to be paid or discharged any
such tax, assessment, charge, levy or claim so long as the validity or amount
thereof shall be contested in good faith by appropriate proceedings and for
which disputed amounts adequate reserves (in the good faith judgment of the
Board of Directors of the Company or any Subsidiary, as the case may be) have
been established.

SECTION 1006.  MAINTENANCE OF PROPERTIES, INSURANCE; BOOKS AND RECORDS;
COMPLIANCE WITH LAW.

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,
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; provided, however, that nothing in this subsection (2) shall
prevent the Company or any Subsidiary from discontinuing the operation and
maintenance of any of its properties if such discontinuance is, in


                                          69
<PAGE>

the good faith judgment of the Board of Directors of the Company, desirable in
the conduct of its business and not disadvantageous in any material respect to
the Debentureholders.

     (3)  The Company and each of its Subsidiaries shall keep proper books of
record and account, in which full and correct entries shall be made of all
financial transactions and the assets and business of the Company and each
Subsidiary, in accordance with GAAP consistently applied to the Company and its
Subsidiary taken as a whole.

     (4)  The Company and each of its Subsidiaries shall comply with all
statutes, laws, ordinances, or government rules and regulations, including
rules, regulations and orders of governmental agencies, decrees, orders,
injunctions, writs to which it is subject, noncompliance with which would
adversely affect the business, prospects, earnings, properties, assets or
condition (financial or otherwise) of the Company and its Subsidiary taken as a
whole.

SECTION 1007.  LIMITATION ON ADDITIONAL INDEBTEDNESS.

     The Company shall not, and shall not permit any Subsidiary to, create,
incur, assume or issue, directly or indirectly, or guarantee or in any manner
become, directly or indirectly, liable for or with respect to the payment of any
Indebtedness, except for:

     (1)  Indebtedness under the Debentures and this Indenture;

     (2)  Indebtedness of the Company and any Subsidiary not otherwise referred

associated therewith) that, immediately after giving pro forma effect to the
incurrence thereof, does not cause the ratio of Adjusted Total Liabilities to
Consolidated Tangible Net Worth to exceed 7:1; or

     (4)  any deferrals, renewals, extensions, replacements, refinancings or
refundings of, or amendments, modifications or supplements to, Indebtedness
incurred under clause (2) or clause (3) above, whether involving the same or any
other lender or creditor or group of lenders or creditors, provided that any
such deferrals, renewals, extensions, replacements, refinancings, refundings,
amendments, modifications or supplements (i) shall not provide for any mandatory
redemption, amortization or sinking fund requirement in an amount greater than
or at a time prior to the amounts and times specified in the Indebtedness being
deferred, renewed, extended, replaced, refinanced, refunded, amended, modified
or supplemented, (ii) shall not exceed the principal amount (plus accrued
interest and prepayment premium, if any) of the Indebtedness being renewed,

SECTION 1008.  LIMITATIONS ON RESTRICTED PAYMENTS.

     The Company shall not make and shall not permit any Subsidiary to make,
directly or indirectly, any Restricted Payment; provided, however, that the
Company may make S Corp Tax Dividends if at the time of such action no Default
or Event of Default exists or would result therefrom; and provided further that
the Company may make such additional Restricted Payments:

     (1)  if at the time of such action no Default or Event of Default exists or
would result therefrom; and

     (2)  if at the time, upon giving effect to such Restricted Payment, the
Company could  incur at least $1.00 of Indebtedness pursuant to paragraph (3) of

     (3)  if, immediately after giving effect to such Restricted Payment, the
aggregate of all Restricted Payments declared or made from the date of this
Indenture, through and including the date of such Restricted Payment (the "Base

during the Base Period and 100% of the aggregate net proceeds received by the
Company from the issue or sale during the Base Period of capital stock of the
Company.

of transactions with or for the benefit of any Affiliate or any Subsidiary of
the Company, or any holder of 5% or more of any class of capital stock of the
Company (each an "Affiliate Transaction"), except in good faith and on terms
that are, in the aggregate, no less favorable to the Company or such Subsidiary,
as the case may be, than those that could have been obtained in a comparable
transaction on an arm's-length basis from a Person not an Affiliate of the
Company or such Subsidiary.  Any loans to the Company or any Subsidiary from any
Affiliate, incurred after the Issue Date, whether by deferrals, renewals,

notify every Affiliate who makes a loan to the Company after the Issue Date of
the Company's agreement under this Section 1009, and the Company shall obtain an
agreement from every Affiliate making a loan to the Company to the effect that

those under or pursuant to the agreement being replaced or the agreement
evidencing the Indebtedness being refinanced or replaced.

SECTION 1011.  NET WORTH.

     The Company will at all times during the term of the Debentures keep and

Trustee a certificate from the Company's independent public accountants as to
subsequent compliance to cure any such default.
