                      ULTRAMAR DIAMOND SHAMROCK CORPORATION

     UDS was the  surviving  corporation  in the  merger  of two  leading  North
American independent refining and marketing companies,  Ultramar Corporation and
Diamond Shamrock, Inc., effective in December 1996. UDS is a leading independent
refiner and marketer of high-quality  petroleum products in the Southwest United
States,  the Northeast United States and Eastern Canada.  On September 25, 1997,
UDS completed the acquisition of Total Petroleum (North America) Ltd. ("Total"),
a Denver, Colorado based petroleum refining and marketing company

     In the Southwest United States,  UDS owns and operates a 150,000 barrel per
day (bpd)  refinery,  near  Amarillo,  Texas,  a 90,000  bpd  refinery  near San
Antonio, Texas and a 100,000 bpd refinery near Los Angeles, California. With the
acquisition of Total,  UDS acquired three  additional  refineries,  a 68,000 bpd
refinery in Ardmore,  Oklahoma,  a 51,000 bpd  refinery in Alma,  Michigan and a
28,000 bpd refinery in Denver,  Colorado.  UDS markets petroleum  products and a
broad range of convenience  store merchandise in the Southwest under the Diamond
Shamrock,  Beacon,  Ultramar,  and  Total  brand  names  through  a  network  of
approximately  6,000  outlets  across  22  central  and  southwest  states.  The
Southwest  operations  also  include the storing  and  marketing  of natural gas
liquids, and the manufacture and marketing of anhydrous ammonia and polymergrade
propylene at its facilities at Mont Belvieu, near Houston, Texas.

     In the  Northeast,  the Company owns and operates a 160,000 bpd refinery in
St. Romuald,  Quebec Canada and markets petroleum products through approximately
1,300 retail  outlets and 84 cardlocks.  In addition,  the Northeast  operations
include  one  of  the  largest   retail  home  heating  oil  businesses  in  the
northeastern  region of North  America,  selling  heating  oil to  approximately
300,000 households.

     In January,  1998,  UDS announced  that it had entered into a memorandum of
understanding  regarding the formation of a refining and marketing joint venture
with Petro-Canada, one of Canada's largest integrated oil and gas companies. UDS
will contribute  substantially  all of its  Northeastern  assets to the venture,
including the Alma,  Michigan  refinery and 187 company operated Michigan retail
sites  acquired  from Total.  The joint venture will operate  refineries  with a
total   throughput   capacity  of  500,000  bpd  and  market  gasoline   through
approximately  3,500  retail  outlets.  It will  operate  UDS's home heating oil
marketing  businesses in the northeastern  United States and Canada.  Control of
the joint venture will be shared.  Petro-Canada  will own 51% and UDS 49% of the
voting units in the  partnership.  Major decisions will require approval of both
partners. Profits from the venture will be shared 64% by Petro-Canada and 36% by
UDS, based upon the relative values of assets each partner expects to contribute
to the joint venture. Formation of the joint venture is subject to completion of
due diligence, definitive documentation,  regulatory review, and the approval of
both  the  UDS  and  Petro-Canada  Boards  of  Directors.  Until  completion  of
regulatory review,  approval of definitive  agreements and closing,  all UDS and
Petro-Canada operations will continue to be run separately.

     The Company's  principal  executive  offices are located at 6000 North Loop
1604  West,  San  Antonio,  TX  78249-1112  and its  telephone  number  is (210)

                                 UDS CAPITAL II

     UDS Capital II is a statutory  business  trust  formed  under  Delaware law
pursuant to (i) a separate declaration of trust (the "Declaration")  executed by
the  Company,  as sponsor  for such trust (the  "Sponsor")  and the UDS  Capital
Trustees (as defined herein) for such trust and (ii) the filing of a certificate
of trust with the Delaware  Secretary of State on June 5, 1997. The  Declaration
of UDS Capital II, as amended, will be qualified as an indenture under the Trust
Indenture  Act of 1939,  as amended (the "Trust  Indenture  Act"),  prior to the
issuance by it of Trust Securities, as herein defined. UDS Capital II exists for
the exclusive purposes of (i) issuing the Trust Preferred  Securities and common
securities  representing  undivided  beneficial  interests  in its  assets  (the
"Common  Securities"  and,  together with the Trust  Preferred  Securities,  the
"Trust  Securities"),  (ii) investing the gross proceeds of the Trust Securities
in a specific series of Partnership  Preferred  Securities and (iii) engaging in
only those other activities  necessary or incidental thereto.  All of the Common
Securities  will be directly or indirectly  owned by UDS. The Common  Securities
will rank pari passu, and payments will be made thereon pro rata, with the Trust
Preferred Securities except that upon an event of default under the Declaration,
the  rights of the  holders of the  Common  Securities  to payment in respect of
distributions and payments upon liquidation,  redemption,  and otherwise will be
subordinated to the rights of the holders of the Trust Preferred Securities. UDS
will  acquire,  directly  or  indirectly,  Common  Securities  in  an  aggregate
liquidation  amount  equal to 3% of the total  capital  of UDS  Capital  II. UDS
Capital II's  business  and affairs will be conducted by the trustees  (the "UDS
Capital Trustees") appointed by UDS, as the direct or indirect holder of all the
Common  Securities.  Except in certain limited  circumstances  the holder of the
Common  Securities  will be entitled to appoint,  remove,  or replace any of, or
increase  or reduce the number of, the UDS  Capital  Trustees of UDS Capital II.
The duties and obligations of the UDS Capital  Trustees shall be governed by the
Declaration.  A majority of the UDS Capital Trustees (the "Regular Trustees") of
UDS Capital II will be persons who are  employees  or officers of or  affiliated
with  UDS.  One UDS  Capital  Trustee  of UDS  Capital  II  will be a  financial
institution  which will be unaffiliated  with the Company and which shall act as
property  trustee and as indenture  trustee for purposes of the Trust  Indenture
Act,  pursuant to the terms set forth in a Prospectus  Supplement (the "Property
Trustee"). In addition,  unless the Property Trustee maintains a principal place
of business in the State of Delaware,  and otherwise  meets the  requirements of
applicable  law,  one UDS  Capital  Trustee  of UDS  Capital  II will  have  its
principal  place of business or reside in the State of Delaware  (the  "Delaware
Trustee").  The Company will pay all fees and expenses related to UDS Capital II
and the offering of Trust Securities, the payment of which will be guaranteed by
the Company.  The office of the Delaware Trustee for UDS Capital II in the State
of Delaware is The Bank of New York (Delaware), 23 White Clay Center, Route 273,
Newark,  Delaware 19711. The principal place of business of UDS Capital II shall
be c/o Ultramar  Diamond  Shamrock  Corporation,  6000 North Loop 1604 West, San
Antonio, Texas 78249-1112 and its telephone number is (210) 592-2000.

                              UDS FUNDING II, L.P.

     UDS Funding II, L. P. is a limited  partnership  formed  under the Delaware
Revised Uniform Limited  Partnership Act, as amended (the "Partnership  Act") on
June 5,  1997.  Pursuant  to the  Certificate  of  Limited  Partnership  and the
Agreement of Limited Partnership, UDS is the sole general partner of UDS Funding
II, L.P. (in such capacity the "General  Partner").  It is anticipated  that UDS
Funding II, L.P. will issue its limited partnership  interests to UDS Capital II
simultaneous with UDS Capital II's issuance of Trust Preferred Securities,  that
it will use the  proceeds  of such  limited  partnership  interest  to  purchase
Subordinated   Debt  Securities,   Affiliate   Debentures,   and  Eligible  Debt
Securities, as herein defined, and that UDS will contribute capital in an amount
sufficient  to establish  its initial  capital  account at an amount equal to at
least 15% of the total capital of UDS Funding II, L.P.

     UDS Funding II, L.P. will be managed by the General  Partner and exists for
the sole purpose of (i) issuing its  partnership  interests,  (ii) investing the
proceeds thereof in Subordinated  Debt  Securities,  Affiliate  Debentures,  and
certain  U.S.  government  obligations  and  commercial  paper of  entities  not
affiliated with UDS (the "Eligible Debt  Securities") and (iii) engaging in only
those other  activities  necessary  or  incidental  thereto.  To the extent that
aggregate  payments to UDS Funding II, L.P. on the Subordinated Debt Securities,
the Affiliate  Debentures and the Eligible Debt Securities exceed  distributions
payable with respect to the Partnership  Preferred  Securities,  UDS Funding II,
L.P.  may at times have excess funds which shall be allocated to and may, in the
General Partner's sole discretion, be distributed to the General Partner. To the
extent that the issuers (including,  where applicable, UDS, as guarantor) of the
securities  in which UDS Funding II, L.P.  invests  fail to make any payments in
respect of such securities (or, if applicable, guarantees), UDS Funding II, L.P.
will not have sufficient funds to pay and will not declare or pay  distributions
on the Partnership Preferred Securities.

     For so long as the Partnership Preferred Securities remain outstanding, the
General Partner will covenant in the Limited Partnership Agreement (i) to remain
the sole  general  partner  of UDS  Funding  II,  L.P.  and to  maintain  direct
ownership  of 100% of the General  Partner's  interest in UDS Funding II,  L.P.,
which  interest will at all times  represent at least 1% of the total capital of
UDS  Funding  II,  L.P.,  (ii) to cause UDS Funding II, L.P. to remain a limited
partnership  and  not  to  voluntarily  dissolve,   liquidate,   wind-up  or  be
terminated,  except as permitted by the Limited Partnership Agreement,  (iii) to
use its commercially reasonable efforts to ensure that UDS Funding II, L.P. will
not be an "investment  company" for purposes of the 1940 Act and (iv) to take no
action  that would be  reasonably  likely to cause UDS  Funding  II,  L.P. to be
classified as an association  taxable as a corporation for United States federal
income tax purposes.

     The  rights  of  the  holders  of  the  Partnership  Preferred  Securities,
including  economic  rights,  rights to information  and voting rights,  are set
forth  in the  Limited  Partnership  Agreement  and  the  Partnership  Act.  See
"Description of the Partnership Preferred Securities."

     The Limited  Partnership  Agreement  provides that the General Partner will
have  liability  for the fees and  expenses of the  Partnership  (including  any
taxes,  duties,  assessments or  governmental  charges of whatever nature (other
than  withholding  taxes)  imposed  by the United  States or any other  domestic
taxing authority upon UDS Funding II, L.P.) and be responsible for all debts and
obligations of UDS Funding II, L.P. (other than with respect to distributions on
the Partnership  Preferred  Securities).  Under Delaware law, assuming a limited
partner in a Delaware limited  partnership such as UDS Funding II, L.P. (i.e., a
holder of the  Partnership  Preferred  Securities)  does not  participate in the
control of the business of the limited  partnership,  such limited  partner will
not be personally  liable for the debts,  obligations,  and  liabilities of such
limited partnership,  whether arising in contract, tort, or otherwise, solely by
reason of being a limited  partner of such limited  partnership  (subject to any
obligation  such limited  partner may have to repay any funds that may have been
wrongfully distributed to such limited partner).

     The location of the principal  executive offices of UDS Funding II, L.P. is
c/o  Ultramar  Diamond  Shamrock  Corporation,  6000 North  Loop 1604 West,  San
Antonio, Texas 78249-1112 and its telephone number is (210) 592-2000.

    RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

     The  following  table sets forth the ratio of earnings  to  combined  fixed
charges and preferred  stock dividends for the Company for each of the following
periods:

                                           Year Ended December 31,

     For the  purpose of this  computation,  earnings  consist of income  before
income  taxes,   extraordinary  items,  and  cumulative  effect  of  changes  in
accounting  principle,  plus fixed charges (excluding  capitalized  interest but
including  amortization  of  amounts  previously  capitalized),  less  equity in
undistributed  earnings of companies  owned less than 50 percent.  Fixed charges
consist  of  interest  (including  capitalized  interest)  on all  indebtedness,
amortization  of debt discount and expense,  and that portion of rental  expense
which the Company believes to be representative of interest. A statement setting
forth the computation of the unaudited ratio has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part.


                                 USE OF PROCEEDS

     UDS Capital II will use all  proceeds  received  from the sale of the Trust
Preferred  Securities  to purchase  Partnership  Preferred  Securities  from UDS
Funding II, L.P. UDS Funding II, L.P.  will use all proceeds  received  from the
sale of the  Partnership  Preferred  Securities  to purchase  Subordinated  Debt
Securities,  Affiliated  Debentures  and Eligible Debt  Securities.  UDS and the
subsidiaries of UDS which are the issuers of the Affiliate  Debentures intend to
add the net  proceeds  from  the sale of the  Subordinated  Debt  Securities  or
Affiliate  Debentures,  as applicable,  along with the proceeds from the sale of
Senior Debt  Securities,  Common  Stock,  and  Preferred  Stock to their general
funds,  to  be  used  for  general   corporate   purposes,   including   capital
expenditures,  repayment or repurchases of outstanding  long-term  indebtedness,
investments in subsidiaries, working capital, repayment of short-term commercial
paper notes and/or other business purposes.  Funds not required  immediately for
such purposes may be invested in marketable securities and short-term
investments.

                      DESCRIPTION OF SENIOR DEBT SECURITIES

     The Senior Debt Securities  will be unsecured  obligations of UDS issued in
one or more series under an  indenture  (the  "Senior  Indenture")  entered into
between UDS and The Bank of New York, as trustee (the "Trustee") effective March
15, 1995,  which is incorporated by reference as an exhibit to the  Registration
Statement of which this Prospectus is a part. The following summaries of certain
provisions of the Senior Indenture do not purport to be complete and are subject
to, and are qualified in their  entirety by reference to, all the  provisions of
the Senior Indenture.  Wherever particular provisions of the Senior Indenture or
terms defined  therein are referred to herein or in the  Prospectus  Supplement,
such  provisions  or  terms  are  incorporated  by  reference  as a part  of the
statements  made,  and the  statements  are qualified in their  entirety by such
reference.   Section  references  are  references  to  sections  of  the  Senior
Indenture.  Capitalized  terms not  otherwise  defined  herein have the meanings
given to them in the Senior Indenture.

General

     The Senior Debt  Securities  will rank equally with all other unsecured and
unsubordinated  debt of UDS. The Senior  Indenture  does not limit the amount of
Debt which may be issued by UDS under the Senior  Indenture  or  otherwise.  The
Senior Indenture does, however, limit the ability of UDS's Subsidiaries to Incur
Debt and issue any Preferred  Stock. The Senior Debt Securities may be issued in
one or more series with the same or various  maturities,  at par or a premium or
with original issue discount and may include medium-term notes.

     Reference is made to the Prospectus  Supplement for the following  terms of
the  Senior  Debt  Securities  offered  pursuant  to  this  Prospectus  and  the
Prospectus  Supplement:  (i) the designation of and any limit upon the aggregate
principal  amount of such  Senior Debt  Securities;  (ii) the price or prices at
which such Senior Debt Securities will be offered  (expressed as a percentage of
the principal amount thereof); (iii) the date or dates on which such Senior Debt
Securities will mature;  (iv) the currency or currencies of denomination of such
Senior Debt  Securities,  which may be U.S.  dollars or any foreign  currency or
units based on or related to currencies;  (v) the designation of the currency or
currencies,  or units based on or related to currencies, in which payment of the
principal  of and any  premium and any  interest on such Senior Debt  Securities
will be made, and if any such amounts are to be payable,  at the election of UDS
or a Holder,  in a currency or currencies or units other than that in which such
Senior Debt  Securities  are stated to be payable,  the period or periods within
which, and the terms and conditions upon which,  such election may be made; (vi)
the rate or rates (which may be fixed or floating)  per annum,  if any, at which
such Senior Debt Securities will bear interest or the method of determining such
rate or  rates;  (vii) the date or dates  from  which  any such  interest  shall
accrue,  the Interest  Payment Dates on which any such interest shall be payable
and the Regular  Record Date for any interest  payable on any  Interest  Payment
Date;  (viii)  any  index  of  currencies,  securities  or  commodities  used to
determine  the  amounts of  payments  of  principal,  (and  premium,  if any) or
interest,  if any, on such Senior Debt  Securities;  (ix) any  provision for the
exchange  or  conversion  of such Senior  Debt  Securities  at the option of the
Holders or UDS for or into  securities  or other  property;  (x) any optional or
mandatory redemption or repayment terms or any sinking or purchase fund or other
analogous  obligation;   (xi)  the  denominations  in  which  such  Senior  Debt
Securities  shall be  issuable  if other  than  denominations  of $1,000 and any
integral multiple  thereof;  (xii) whether such Senior Debt Securities are to be
issued  in the  form of  Global  Securities  and,  if so,  the  identity  of the
Depositary  with  respect  to such  Global  Securities;  (xiii)  in the  case of
Discount  Securities,  the principal amount thereof payable upon acceleration of
the maturity  thereof;  and (xiv) any other specific terms  associated with such
Senior Debt Securities.

     Unless  otherwise set forth in the applicable  Prospectus  Supplement,  the
principal of and any premium and any interest on the Senior Debt  Securities  is
payable to registered  Holders of Senior Debt Securities at the principal office
of the Trustee in New York, New York, or at any paying agency  maintained at the
time by UDS for such  purpose.  At the  option of UDS,  payment of  interest  to
registered  holders of Senior Debt Securities may be made by check mailed to the
address of the person entitled  thereto as it appears on the register for Senior
Debt Securities.

     The Senior Debt Securities  shall be issued in fully registered form unless
the  Prospectus  Supplement  provides  otherwise.  (Section  301) Subject to the
limitations  provided in the Senior  Indenture,  Senior Debt  Securities  may be
presented for registration of transfer or exchange at such office of the Trustee
or at such other  location or  locations as may be  established  pursuant to the
Senior Indenture without any service charge, although UDS may require payment of
a sum  sufficient  to cover  any tax or other  governmental  charge  payable  in
connection therewith. (Section 305)

Global Securities

     The Senior Debt Securities may be issued in whole or in part in the form of
one or more Global  Securities that will be deposited with, or on behalf of, the
Depositary  identified in the Prospectus  Supplement.  Global  Securities may be
issued only in fully  registered form and in either temporary or permanent form.
Unless and until it is exchanged in whole or in part for the  individual  Senior
Debt Securities  represented  thereby,  a Global Security may not be transferred
except as a whole by the  Depositary  for such  Global  Security to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or another
nominee  of  such  Depositary  or by the  Depositary  or  any  nominee  of  such
Depositary to a successor Depositary or any nominee of such successor.

     The specific  terms of any  depositary  arrangement  with respect to Senior
Debt  Securities  issued in the form of one or more  Global  Securities  will be
described  in the  Prospectus  Supplement.  Unless  otherwise  specified  in the
Prospectus  Supplement,  the following  provisions  will apply to all depositary
arrangements.

     Upon the  issuance of a Global  Security,  the  Depositary  for such Global
Security or its nominee will credit on its book-entry  registration and transfer
system the respective principal amounts of the individual Senior Debt Securities
represented by such Global  Security to the accounts of  institutions  that have
accounts  with  such  Depositary   ("Participants").   Such  accounts  shall  be
designated by the underwriters,  dealers,  or agents with respect to such Senior
Debt  Securities or by UDS if such Senior Debt  Securities  are offered and sold
directly by UDS.  Owners of beneficial  interests in a Global  Security that are
not  Participants  or persons that may hold through  Participants  but desire to
sell or otherwise transfer ownership of such beneficial  interests by book-entry
on the records of the Depositary may do so only through Participants and persons
that may hold  through  Participants.  Because  the  Depositary  can only act on
behalf of  Participants  and persons  that may hold  through  Participants,  the
ability of an owner of a beneficial interest in a Global Security to pledge such
beneficial  interests  to persons or  entities  that do not  participate  in the
book-entry and transfer system of the  Depositary,  or otherwise take actions in
respect of such beneficial  interests,  may be limited.  The laws of some states
require that certain  purchasers  of securities  take physical  delivery of such
securities in definitive  form. Such  limitations on the ownership of beneficial
interests in a Global  Security and such laws may impair the ability to transfer
beneficial interests in a Global Security.

     So long as the  Depositary  for a Global  Security  or its  nominee  is the
registered  owner of such Global Security,  such Depositary or such nominee,  as
the case may be, will be considered  the sole owner or holder of the Senior Debt
Securities represented by such Global Security for all purposes under the Senior
Indenture.  Except as provided below, owners of beneficial interests in a Global
Security  will  not be  entitled  to  have  any of the  individual  Senior  Debt
Securities of the series represented by such Global Security registered in their
names,  will not receive or be entitled to receive physical delivery of any such
Senior  Debt  Securities  of such  series  in  definitive  form  and will not be
considered the owners or holders thereof under the Senior Indenture.

     Payments of principal of (and  premium,  if any) and  interest,  if any, on
individual Senior Debt Securities represented by a Global Security registered in
the name of a Depositary  or its nominee will be made to the  Depositary  or its
nominee,  as the case may be, as the  registered  owner of the  Global  Security
representing such Senior Debt Securities.  None of UDS, the Trustee,  any paying
agent or registrar for such Senior Debt Securities will have any  responsibility
or  liability  for any aspect of the records  relating  to, or payments  made on
account of,  beneficial  ownership  interests  in the Global  Security  for such
Senior Debt Securities or for maintaining,  supervising or reviewing any records
relating to such beneficial ownership interests.

     UDS expects that the Depositary  for a series of Senior Debt  Securities or
its nominee,  upon receipt of any payment of principal,  premium, or interest in
respect of a Global Security  representing  any of such Senior Debt  Securities,
immediately  will  credit  Participants'   accounts  with  payments  in  amounts
proportionate to their respective  beneficial  interests in the principal amount
of such  Global  Security  as shown on the  records  of such  Depositary  or its
nominee.  UDS also expects that payments by Participants to owners of beneficial
interests  in such  Global  Security  held  through  such  Participants  will be
governed by standing  instructions and customary  practices,  as is now the case
with  securities held for the accounts of customers in bearer form or registered
in "street name." Such payments will be the  responsibility of such Participants
and not of UDS or the  Depositary.  Owners  of  beneficial  interests  in Global
Securities  may  experience  some delay in the receipt of interest and principal
payments since the Depositary for such Global  Securities will forward  payments
to its  Participants,  which in turn  will  forward  them to  persons  that hold
beneficial interests in such Global Securities through such Participants.

     If a  Depositary  for a series of  Senior  Debt  Securities  is at any time
unwilling,  unable or  ineligible  to  continue  as  depositary  and a successor
depositary  is not  appointed by UDS within 90 days,  UDS will issue  individual
Senior Debt  Securities  of such series in  definitive  form in exchange for the
Global Security representing such series of Senior Debt Securities. In addition,
UDS may at any time  and in its  sole  discretion,  subject  to any  limitations
described in the  Prospectus  Supplement,  determine not to have any Senior Debt
Securities of such series  represented by one or more Global  Securities and, in
such  event,  will issue  individual  Senior Debt  Securities  of such series in
exchange  for the Global  Security  or  Securities  representing  such series of
Senior  Debt  Securities.  In  either  instance,  UDS  will  issue  Senior  Debt
Securities in definitive form, equal in aggregate principal amount to the Global
Securities,  in such names and in such  principal  amounts as the Depositary for
such Global Securities shall request.  Individual Senior Debt Securities of such
series so issued will be issued in denominations,  unless otherwise specified by
UDS, of $1,000 and integral multiples thereof.

Covenants

     The  covenants  summarized  below  will be  applicable  (unless  waived  or
amended) so long as any of the Senior Debt  Securities are  outstanding,  unless
stated otherwise in the Prospectus Supplement.

     Limitation on Subsidiary Debt and Preferred Stock

of a particular  series;  (ii) Debt under the Bank Credit  Agreements  and other

similar agreements and foreign currency swap, exchange or similar agreements for
the purpose of  providing a hedge to protect  against  fluctuations  in interest

incidental to, the ordinary course of business or are entered into in connection
with the incurrence of Debt permitted hereunder;  (iv) Debt Incurred pursuant to
industrial revenue or development bonds in an aggregate  principal amount not to
exceed $50 million at any one time outstanding;  (v) Debt Incurred or Incurrable

transaction  in which such Person  becomes a Subsidiary  of UDS),  which Debt or
Preferred Stock was not incurred or issued in anticipation of such  transaction;
(viii)  Debt  Incurred  for the  purpose  of  financing  all or any  part of the
purchase price or the cost of construction  of or improvements  (or additions to

principal  amount  not to  exceed  the  fair  market  value  of  such  property,
construction  or  improvements  (or  additions  to  improvements);  (ix) Debt or
Preferred  Stock that is  exchanged  for,  or the  proceeds of which are used to
refinance or refund,  any Debt or Preferred  Stock  permitted to be  outstanding
pursuant to clauses (i) through (viii) (or any extension or renewal thereof) (A)
in an aggregate  principal amount (which, in the case of Debt or Preferred Stock
that is a Discount Security, shall be the issue price thereof) not to exceed the
principal amount of the Debt, in the case of Debt, or the liquidation preference
of  the  Preferred  Stock,  in  the  case  of  Preferred  Stock,  so  exchanged,
refinanced, or refunded (which, in the case of Debt or Preferred Stock that is a
Discount Security, shall be the accreted value thereof, as determined by UDS for
financial  reporting  purposes as of the date of such  exchange,  refinancing or
refunding)  and (B) provided that such Debt or Preferred  Stock does not require
the payment of all or a portion of the  principal or  liquidation  value thereof

default  thereunder and any redemption or other  retirement at the option of the
holder  of such  Debt or  Preferred  Stock  (including  pursuant  to an offer to
purchase)  which  is  conditioned  upon  the  change  of  control  of UDS or any

     UDS shall not Incur any Lien on  property  or assets of UDS to secure  Debt
without making  effective  provision for securing the Senior Debt  Securities of
each  series  having the  benefit of this  covenant  (and,  if  required  by its
governing  instruments,  any other  Debt of UDS that is not  subordinate  to the
Senior Debt  Securities of such series) equally and ratably with such Debt as to
such  property for so long as such Debt will be so secured or, in the event such
Debt is Debt of UDS which is  subordinate in right of payment to the Senior Debt
Securities of such series, prior to such Debt as to such property for so long as
such Debt will be so secured.

     With  respect  to any  particular  series of Senior  Debt  Securities,  the
foregoing  restrictions  will not apply to:  (i) Liens  existing  at the date of
original issuance of such series of Senior Debt Securities;  (ii) Liens securing
Debt Incurred under the Bank Credit Agreements or other Liens on inventories and
accounts  receivable existing from time to time; (iii) Liens securing the Senior
Debt  Securities of such series;  (iv) Liens on property of a Person existing at
the time such Person is merged into or  consolidated  with UDS and not  securing
Debt  Incurred  in  anticipation  of such  transaction;  (v)  Liens on  property
existing at the time of acquisition thereof;  (vi) Liens to secure Debt Incurred
for the purpose of financing  all or any part of the purchase  price or the cost
of construction or improvement  (or additions to  improvements)  of the property
subject to such  Liens;  (vii)  Liens on  property of UDS in favor of the United
States of America or any state thereof,  or any  instrumentality  of either,  or
Canada or any province  thereof,  or any  instrumentality  of either,  to secure
certain  payments  pursuant to any contract or statute;  (viii) Liens granted to
any bank or other  institution on cash,  marketable  securities or other current
assets to secure  obligations  under any interest rate swap or similar agreement
or foreign  currency  swap,  exchange  or similar  agreement  for the purpose of
providing a hedge to protect against fluctuations in interest rates and currency
exchange rates, respectively,  and not for the purpose of speculation,  provided
that such  agreements  are entered into in, or are  incidental  to, the ordinary
course of business, between UDS and such institution;  (ix) Liens granted to any
bank or other  institution on the payments to be made by such institution to UDS
pursuant to any  interest  rate swap or similar  agreement  or foreign  currency
hedge,  exchange or similar  agreement  designed to provide  protection  against
fluctuations  in  interest  rates and  currency  exchange  rates,  respectively,
provided that such  agreements  are entered into in, or are  incidental  to, the
ordinary  course  of  business;  (x)  Liens  to  secure  industrial  revenue  or
development  bonds, not to exceed $50 million at any one time outstanding;  (xi)

refunding (or successive extensions,  renewals,  refinancings or refundings), in
whole or in part,  of any Debt  secured by Liens  referred  to in the  foregoing
clauses  (i) to (xi) so long as such Lien does not extend to any other  property
and the Debt so secured is not increased;  (xiii) Liens incurred in the ordinary
course of business that are not material to the business or financial  condition
of UDS and its Subsidiaries  taken as a whole and which do not secure Debt in an
aggregate principal amount in excess of $25 million at any one time outstanding;
and (xiv)  any  Liens  securing  Debt  owed by UDS to one or more  Wholly  owned
Subsidiaries  of UDS  (but  only if such  Debt  is  held  by such  Wholly  owned
Subsidiaries). (Section 1007)

     Limitation on Sale and Leaseback Transactions

     UDS shall not enter into any Sale and Leaseback  Transaction  (except for a
period not exceeding  three years) unless:  (1) UDS would be entitled to Incur a
Lien to secure Debt by reason of the provisions described in clauses (i) through
(xiv) of the second  paragraph  under the  "Limitation on Liens"  covenant in an
amount equal to the  Attributable  Value of such Sale and Leaseback  Transaction
without equally and ratably  securing all Outstanding  Senior Debt Securities of
each series  having the benefit of this  covenant or (2) UDS applies  within one
year an amount equal to the Net  Available  Proceeds of the sale pursuant to the
Sale and  Leaseback  Transaction  (A) to the  repayment  of Debt  under the Bank
Credit  Agreements  to the extent  required,  then (under each of the  following
clauses to the extent,  if any,  that Net  Available  Proceeds  remain after the
prior  applications)  (B)  at  UDS's  option,  to  the  acquisition  of,  or the
construction of  improvements  (or additions to  improvements)  to, assets to be
used in  lines of  business  of UDS and its  Subsidiaries  as of the date of the
Senior Indenture or in activities incidental thereto, then (c) to the redemption
of the Senior Debt Securities of each series having the benefit of this covenant
(if then permitted) on a pro rata basis or, if the Senior Debt Securities of any
such series are not then redeemable, UDS shall apply any remaining Net Available
Proceeds to defease  the Senior  Debt  Securities  of any such  series,  if then
permitted  under the defeasance  provisions of the Senior  Indenture;  provided,
however,  that nothing  contained in this covenant of the Senior Indenture shall
obligate UDS to redeem or defease the Senior Debt  Securities of any series that
are redeemable only upon the payment of a premium above the principal amount or,
if the Senior Debt  Securities  of such  Series are  Discount  Securities,  at a
premium  above the  portion of such  principal  amount that would at the time be
payable  upon  acceleration  following  an  Event  of  Default,  then (D) to the
repayment of Company Debt that is pari passu with the Senior Debt  Securities of
any such series or  Subsidiary  Debt,  in each case to the extent that such Debt
can be repaid without premium or penalty, and then (E) to the repayment of other
Company or Subsidiary Debt. (Section 1008)

     Mergers, Consolidations and Certain Sales of Assets

     UDS may not (i) (A)  consolidate  with or merge into any other Person,  (B)
permit any other Person to consolidate  with or merge into UDS or (c) permit any
other Person to consolidate with or merge into any Significant Subsidiary of UDS
(except in a transaction  in which such  Significant  Subsidiary  ceases to be a
Subsidiary of UDS);  or (ii) directly or  indirectly,  transfer,  convey,  sell,
lease, or otherwise  dispose of all or  substantially  all of its properties and
assets as an entirety,  unless:  (a)  immediately  after  giving  effect to such
transaction and treating any Debt Incurred by UDS or a Subsidiary as a result of
such  transaction as having been Incurred by UDS or such  Subsidiary at the time
of the  transaction,  no Event of Default  with  respect to any series of Senior
Debt  Securities or event that with the passing of time or the giving of notice,
or both,  shall  constitute  an Event of Default  with  respect to any series of
Senior  Debt  Securities  shall  have  occurred  and  be  continuing;  (b)  in a
transaction  in which UDS does not survive or in which UDS  transfers,  conveys,
sells,  leases or otherwise  disposes of all or substantially all its properties
and  assets as an  entirety,  the  successor  entity to UDS or such  assets is a
corporation, partnership, or trust which is organized and validly existing under
the laws of the United  States of America,  any State thereof or the District of
Columbia and will expressly assume, by a supplemental  Senior Indenture executed
and delivered to the Trustee in form  satisfactory to the Trustee,  all of UDS's
obligations under the Senior Indenture relating to the Senior Debt Securities of
each series having the benefit of this covenant; (c) if, as a result of any such
transaction,  property  or assets of UDS would  become  subject  to a Lien which
would  require UDS to equally and ratably  secure the Senior Debt  Securities of
each series having the benefit of this covenant  pursuant to the  "Limitation on
Liens" covenant, UDS or the successor entity to UDS will have secured the Senior
Debt  Securities of each such series as required by such  covenant;  and (d) UDS
has delivered to the Trustee an Officers'  Certificate and an Opinion of Counsel
as specified in the Senior Indenture. (Section 801)

 Events of Default; Waiver and Notice Thereof; Senior Debt Securities in Foreign
                                   Currencies

As to any series of Senior  Debt  Securities,  an Event of Default is defined in
the Senior  Indenture  as being any one of the  following  events and such other
events as may be established for the Senior Debt Securities of such series:  (a)
failure to pay any  interest on the Senior Debt  Securities  of such series when
due, continued for 30 days; (b) failure to pay principal of (or premium, if any,
on) the Senior Debt  Securities  of such series when due; (c) failure to pay any
sinking  fund,  purchase,  or other  analogous  obligation,  if any,  when  due,
pertaining to such series of Senior Debt  Securities;  (d) failure to perform or

Sales of  Assets,"  continued  for 30 days;  (e)  failure to  perform  any other

the Senior Indenture for the benefit of such series, continued for 60 days after
written notice as provided in the Senior Indenture;  (f) failure to pay when due
at final maturity (after the expiration of any applicable grace period), or upon
the  acceleration of, any Debt of UDS or any of its Subsidiaries in an aggregate
principal  amount  in  excess  of  $50  million,  if  such  indebtedness  is not
discharged,  or such acceleration is not annulled,  within 60 days after written
notice  as  provided  in the  Senior  Indenture;  (g) the  rendering  of a final
judgment  or  judgments  (not  subject  to  appeal)  against  UDS  or any of its
Subsidiaries in an aggregate  amount in excess of $25 million (to the extent not
covered by insurance)  which remains  unstayed,  undischarged  or unbonded for a
period of 30 days thereafter; or (h) certain events of bankruptcy, insolvency or
reorganization   affecting  UDS  or  any  Significant  Subsidiary  of  UDS.  Any
additional  Events of Default  applicable to a particular  series of Senior Debt
Securities are described in the Prospectus Supplement relating to such series.
(Sections 301 and 501)

     The Senior Indenture  provides that (i) if an Event of Default described in
clause (a),  (b), (c), (d), (e), (f) or (g) above (in the case of clause (e), if
the Event of  Default is with  respect  to less than all  series of Senior  Debt
Securities then Outstanding)  shall have occurred and be continuing with respect
to Senior Debt Securities of any series,  then either the Trustee or the Holders
of not less than 25% in aggregate principal amount of the Senior Debt Securities
of each series then  Outstanding  (each such series acting as a separate  class)
may declare the principal (or, in the case of Discount  Securities,  the portion
thereof  specified  in  the  terms  thereof)  of  all  Outstanding  Senior  Debt
Securities of such series and the interest  accrued  thereon,  if any, to be due
and payable  immediately;  (ii) if an Event of Default  described  in clause (e)
above with  respect to all series of Senior  Debt  Securities  then  Outstanding
shall have occurred and be continuing, then either the Trustee or the Holders of
not less than 25% in aggregate principal amount of the Senior Debt Securities of
each series then  Outstanding  (treated as one class) may declare the  principal
(or, in the case of Discount  Securities,  the portion thereof  specified in the
terms thereof) of all Senior Debt Securities of such series then Outstanding and
the interest accrued  thereon,  if any, to be due and payable  immediately;  and
(iii) if an Event of Default  described in clause (h) above shall have  occurred
and be continuing,  the principal (or, in the case of Discount  Securities,  the
portion  thereof  specified in the terms thereof) of all Senior Debt  Securities
then  Outstanding  and  the  interest  accrued  thereon,  if any,  shall  become
immediately due and payable;  provided,  however,  that upon certain  conditions
such declarations or accelerations, as the case may be, may be annulled and past
defaults (except for defaults in the payment of principal of, any premium on, or
any interest on the Senior Debt Securities of such series,  or in the payment of
any sinking  fund,  purchase or other  analogous  obligation,  applicable to the
Senior Debt Securities of such series, and in compliance with certain covenants)
may be waived by the Holders of a majority in aggregate  principal amount of the
Senior Debt  Securities  of any series  having the benefit of this covenant then
Outstanding. (Sections 502 and 513)

     Under the Senior  Indenture,  the Trustee  must give to the Holders of each
series of Senior Debt Securities notice of all uncured defaults known to it with
respect to such series within 90 days after such a default  occurs,  unless such
default shall have been cured or waived;  provided that in the case of a default
described  in clause (e) above,  no such notice shall be given until at least 90
days after such default occurs; and provided further that, except in the case of
default in the payment of principal of and any premium or any interest on any of
the Senior Debt Securities, or default in the payment of any sinking or purchase
fund  installment  or analogous  obligations,  the Trustee shall be protected in
withholding  such notice if it in good faith  determines that the withholding of
such notice is in the interests of the Holders of the Senior Debt  Securities of
such series. For the purpose of this paragraph,  the term "default" includes the
events specified above without notice or grace periods. (Section 602)

No Holder of any Senior Debt  Securities  of any series may institute any action
under the Senior  Indenture  unless (a) such Holder shall have given the Trustee
written notice of a continuing Event of Default with respect to such series; (b)
the  Holders of not less than 25% in  aggregate  principal  amount of the Senior
Debt Securities of such series then Outstanding shall have requested the Trustee
to institute proceedings in respect of such Event of Default; (c) such Holder or
Holders shall have offered the Trustee such reasonable  indemnity as the Trustee
may  require;  (d) the Trustee  shall have failed to  institute an action for 60
days thereafter;  and (e) no inconsistent direction shall have been given to the
Trustee  during  such 60-day  period by the  Holders of a majority in  aggregate
principal  amount  of Senior  Debt  Securities  of such  series.  (Section  507)
However,  such  limitations  do not apply to a suit  instituted by the Holder of
Senior Debt  Securities  of any series  entitled to the benefit of this covenant
for enforcement of payment of the principal of (and premium, if any) or interest
on Senior  Debt  Securities  of such  series on or after the  respective  Stated
Maturities  expressed  in the Senior Debt  Securities  of such series (or in the
case of redemption or repayment,  on the Redemption  Date or Repayment  Date, as
the case may be). (Section 508)

     The Holders of a majority in aggregate  principal amount of the Senior Debt
Securities  of any series  affected  and then  Outstanding  will have the right,
subject  to  certain  limitations,  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  with  respect to such  series of
Senior Debt  Securities.  (Section 512) The Senior  Indenture  provides that, in
case an  Event of  Default  shall  occur  and be  continuing,  the  Trustee,  in
exercising its rights and powers under the Senior Indenture, will be required to
use the  degree of care of a prudent  person  in the  conduct  of his or her own
affairs.  The Senior  Indenture  further  provides that the Trustee shall not be
required  to  expend  or risk its own funds or  otherwise  incur  any  financial
liability in the performance of any of its duties under the Senior  Indenture if
it has reasonable grounds for believing that repayment of such funds or adequate
indemnity  against  such risk or  liability  is not  reasonably  assured  to it.
(Section 601)

     UDS must  furnish  to the  Trustee  within  120 days  after the end of each
fiscal  year  an  Officers'  Certificate  to the  effect  that a  review  of the
activities  of UDS  during  such year and of its  performance  under the  Senior
Indenture and the terms of the Senior Debt Securities has been made, and, to the
best of the  knowledge of the  signatories  based on such review,  UDS is not in
default in the performance  and observance of the terms of the Senior  Indenture
or, if UDS is in default, specifying such default. (Section 1004)

     If any Senior Debt Securities are not denominated in United States Dollars,
then for the  purposes  of  determining  whether  the  Holders of the  requisite
principal amount of Senior Debt Securities have taken any action as described in
the Senior Indenture,  the principal amount of such Senior Debt Securities shall
be deemed to be that amount of United States  Dollars that could be obtained for
such  principal  amount on the basis of the spot rate of  exchange  into  United
States  Dollars for the currency or units based on or related to  currencies  in
which such Senior Debt  Securities are  denominated (as evidenced to the Trustee
by an  Officers'  Certificate)  as of the date the taking of such  action by the
Holders  of such  requisite  principal  amount is  evidenced  to the  Trustee as
provided in the Senior Indenture. (Section 104)

     If any  Senior  Debt  Securities  are  Discount  Securities,  then  for the
purposes of determining whether the Holders of the requisite principal amount of
Senior Debt  Securities  have taken any action herein  described,  the principal
amount of such Senior Debt Securities  shall be deemed to be the portion of such
principal amount that would be due and payable at the time of the taking of such
action upon acceleration of the maturity thereof. (Section 101)

     Defeasance

     UDS may discharge  any and all  obligations  in respect of the  Outstanding
Senior Debt  Securities of any series  (except for certain  obligations to issue
temporary Senior Debt Securities of each series and exchange them for definitive
Senior Debt  Securities  of such  series,  register  the transfer or exchange of
Senior Debt Securities of each series, replace mutilated,  destroyed,  lost, and
stolen Senior Debt Securities of each series,  and maintain paying  agencies) if
all Senior Debt  Securities  of such series  mature within one year or are to be
called for redemption  within one year and if (i) UDS irrevocably  deposits with
the  Trustee,  in trust,  (a) money in the  currency  in which the  Senior  Debt
Securities  of a  particular  series are  denominated  in an amount,  or (b) the
equivalent in securities  of the  government  which issued the currency in which
the Senior Debt Securities of such series are denominated or government agencies
backed by the full faith and credit of such government,  or (c) a combination of
(a) and (b),  sufficient,  in the  opinion of a  nationally  recognized  firm of
independent public accountants, to pay the principal of and premium, if any, and
each installment of interest,  if any, on the Outstanding Senior Debt Securities
of such series to maturity or  redemption,  as the case may be, and (ii) certain
other conditions are satisfied. (Section 401)

     UDS may (A) be discharged  from any and all  obligations  in respect of the
Outstanding Senior Debt Securities of any series (except for certain obligations
to issue  temporary  Senior Debt Securities of each series and exchange them for
definitive  Senior Debt  Securities  of such  series,  register  the transfer or
exchange of Senior Debt Securities of each series, replace mutilated, destroyed,
lost and stolen  Senior  Debt  Securities  of each  series and  maintain  paying
agencies) or (B) omit to comply with certain restrictive covenants applicable to
Senior Debt Securities of any series that are described in the Senior  Indenture
(including those described under "Limitation on Subsidiary  Debt,"  "Limitations
on  Liens,"  and  "Limitation  on  Sale  and  Leaseback  Transactions"  and  any
additional  covenants  provided for the benefit of a particular series of Senior
Debt  Securities)  and the events  described  in clauses  (c)  through (g) under
"Events of Default" and any other Events of Default for which this  provision is
specified to be applicable  shall not constitute  Events of Default with respect
to the Senior Debt  Securities  of such  series,  in either case (A) or (B) upon
irrevocable  deposit with the Trustee, in trust, of (i) money in the currency in
which the Senior Debt  Securities of a particular  series are  denominated in an
amount,  or (ii) the equivalent in securities of the government which issued the
currency in which the Senior Debt  Securities of such series are  denominated or
government  agencies backed by the full faith and credit of such government,  or
(iii) a  combination  of (i) and (ii),  which  through  the  payment of interest
thereon and principal  thereof in accordance with their terms will provide,  not
later  than one day  before  the due  date of any  payment,  money in an  amount
sufficient in the opinion of a nationally  recognized firm of independent public
accountants to pay the principal of and premium, if any, and each installment of
interest,  if any, on the applicable  Outstanding Senior Debt Securities of such
series.  The  obligations  with  respect to the Senior Debt  Securities  of such
series  under the Senior  Indenture,  other than with  respect to the  covenants
described  in clause (B) and the Events of  Default  with  respect to the Senior
Debt Securities of such series under the Senior Indenture, other than the Events
of Default described in clause (B), shall remain in full force and effect.  Such
trust may only be established  if, among other things,  (i) UDS has delivered to
the Trustee  (a) a ruling  from the  Internal  Revenue  Service  directed to the
Trustee  or an  Opinion of Counsel  accompanied  by a ruling  from the  Internal
Revenue Service to the effect that the deposit and related  defeasance would not
cause the Holders of the Senior Debt Securities of such series to recognize gain
or loss for United States Federal  income tax purposes,  unless there has been a
change in applicable United States federal income tax law, which, in the opinion
of such counsel,  makes such ruling unnecessary,  which change in federal income
tax law shall be based upon a ruling of the Internal Revenue Service or a change
in applicable  United States Federal  income tax laws occurring  after March 15,
1995;  and (b) an  Officers'  Certificate  to the effect  that the  Senior  Debt
Securities of such series, if then listed on any securities  exchange,  will not
be delisted as a result of such  deposit;  (ii) no Event of Default with respect
to the Senior Debt  Securities  of such series or event that with the passing of
time or the giving of notice, or both, shall constitute an Event of Default with
respect to the Senior Debt  Securities  of such series shall have occurred or be
continuing (a) on the date of such deposit,  or (b) insofar as certain events of
bankruptcy,  insolvency, or reorganization are concerned, at any time during the
period  ending  on the 123rd day  after  the date of such  deposit;  (iii)  such
defeasance or covenant defeasance will not result in the trust arising from such
deposit  being in violation of the  Investment  Company Act of 1940, as amended;
and (iv) certain other conditions are satisfied. (Sections 402 and 403)

     Modification and Waiver

With certain  exceptions,  the Senior  Indenture or the rights of the Holders of
the Senior Debt  Securities  may be  modified  by UDS and the  Trustee  with the
consent of the Holders of a majority in aggregate principal amount of the Senior
Debt Securities of each series affected by such  modification  then Outstanding,
but no such  modification  may be made without the consent of the Holder of each
Outstanding  Senior Debt  Security  affected  thereby which would (a) change the
Maturity of the  principal  of, or the Stated  Maturity of any premium on or any
installment  of interest on any Senior Debt  Security,  or reduce the  principal
amount thereof or the interest or any premium  thereon,  or change the method of
computing  the amount of  principal  thereof or interest  thereon on any date or
change any place of payment where, or the currency (or units based on or related
to  currencies)  in which,  any Senior Debt  Security or any premium or interest
thereon is  payable,  or change the  currency  (or units  based on or related to
currencies)  in which any Senior  Debt  Security is  denominated,  or impair the
right to institute suit for the  enforcement of any such payment on or after the
Maturity or Stated  Maturity,  as the case may be,  thereof  (or, in the case of
redemption or repayment,  on or after the Redemption Date or the Repayment Date,
as the case may be);  (b)  reduce  the  percentage  in  principal  amount of the
Outstanding  Senior Debt Securities of any series,  the consent of whose Holders
is  required  for any such  modification,  or the  consent  of whose  Holders is
required  for any waiver of  compliance  with certain  provisions  of the Senior
Indenture or certain defaults thereunder and their consequences  provided for in
the Senior Indenture; or (c) modify any of the provisions of certain sections of
the Senior  Indenture,  including the provisions  summarized in this  paragraph,
except  to  increase  any such  percentage  or to  provide  that  certain  other
provisions  of the Senior  Indenture  cannot be modified  or waived  without the
consent of the Holder of each Outstanding Senior Debt Security affected thereby.
(Section 902)

Senior  Debt  Securities  of any  series  under the Senior  Indenture  may waive
compliance by UDS with certain  restrictive  provisions of the Senior Indenture.
The  Holders of a majority  in  aggregate  principal  amount of the  Outstanding
Senior Debt  Securities  of any series under the Senior  Indenture may waive any
past  default  under such Senior  Indenture,  except a default in the payment of
principal  of, any premium on, or any interest on the Senior Debt  Securities of
such series, or in the payment of any sinking fund,  purchase or other analogous
obligation  applicable to the Senior Debt  Securities of such series.  (Sections

thereof as determined in accordance with GAAP,  discounted from the last date of
such initial term to the date of  determination at a rate per annum equal to the
discount rate which would be applicable to a Capital Lease  Obligation with like
term in accordance  with GAAP.  The net amount of rent required to be paid under
any such lease for any such period shall be the aggregate amount of rent payable
by the lessee with respect to such period after excluding amounts required to be
paid on account of insurance,  taxes, assessments,  utility, operating and labor
costs and similar  charges.  In the case of any lease which is terminable by the
lessee upon the  payment of a penalty,  such net amount  shall also  include the
amount of such  penalty,  but no rent shall be considered as required to be paid
under  such  lease  subsequent  to  the  first  date  upon  which  it  may be so
terminated.  "Attributable  Value" means, as to a Capital Lease Obligation under
which any  Person is at the time  liable  and at any date as of which the amount
thereof is to be determined, the capitalized amount thereof that would appear on

upon which  such lease may be  terminated  by the  lessee  without  payment of a
penalty.

     "Consolidated Current Assets" of any Person means all assets of such Person
which would,  in accordance  with GAAP,  be  classified  as current  assets of a

Concerning the Trustee

     The Bank of New York is the Trustee under the Senior Indenture.

Governing Law

     The Senior Debt Securities of each series and the Senior Indenture shall be
governed by and construed in accordance with the laws of the State of New York.

                 DESCRIPTION OF THE SUBORDINATED DEBT SECURITIES

     Subordinated Debt Securities may be issued from time to time in one or more
series under an indenture (the "Subordinated  Indenture"),  entered into between
UDS and The Bank of New York, as Trustee (the "Debt Trustee").  The terms of the
Subordinated  Debt  Securities  will include  those  stated in the  Subordinated
Indenture and those made part of the Subordinated  Indenture by reference to the
Trust  Indenture Act. The following  summary does not purport to be complete and
is  subject in all  respects  to the  provisions  of,  and is  qualified  in its
entirety by reference to, the  Subordinated  Indenture,  and the Trust Indenture
Act.  Whenever  particular  provisions  or  defined  terms  in the  Subordinated
Indenture  are  referred  to  herein,  such  provisions  or  defined  terms  are
incorporated by reference herein. Section and Article references used herein are
references to provisions of the Subordinated Indenture unless otherwise noted.

General

     The   Subordinated   Debt  Securities   will  be  unsecured,   subordinated
obligations  of UDS. The  Subordinated  Indenture  does not limit the  aggregate
principal amount of Subordinated  Debt Securities which may be issued thereunder
and provides that the  Subordinated  Debt  Securities may be issued from time to
time in one or more series. The Subordinated Debt Securities are issuable in one
or  more  series  pursuant  to an  Subordinated  Indenture  supplemental  to the
Subordinated  Indenture or a resolution of UDS's Board of Directors or a special
committee appointed thereby (each, a "Supplemental Subordinated Indenture").
(Section 301)

     In the event Subordinated Debt Securities are issued to a UDS Capital II or
a trustee of such trust in connection  with the issuance of Trust  Securities by
UDS  Capital  II,  such  Subordinated   Debt  Securities   subsequently  may  be
distributed pro rata to the holders of such Trust  Securities in connection with
the  dissolution  of UDS  Capital  II upon  the  occurrence  of  certain  events
described in the Prospectus  Supplement relating to such Trust Securities.  Only
one series of Subordinated Debt Securities will be issued to UDS Capital II or a
trustee of such trust in connection with the issuance of Trust Securities by UDS
Capital II.

Reference  is made  to the  Prospectus  Supplement  relating  to the  particular
Subordinated  Debt Securities being offered thereby for the following terms: (1)
the  designation  of  such  Subordinated  Debt  Securities;  (2)  the  aggregate
principal amount of such  Subordinated  Debt  Securities;  (3) the percentage of
their  principal  amount at which  such  Subordinated  Debt  Securities  will be
issued,  (4) the date or dates on which such  Subordinated  Debt Securities will
mature  and the right,  if any,  to extend  such date or dates;  (5) the rate or
rates, if any, per annum, at which such  Subordinated  Debt Securities will bear
interest,  or the method of determination of such rate or rates; (6) the date or
dates from which such interest shall accrue, the interest payment dates on which
such  interest will be payable or the manner of  determination  of such interest
payment  dates and the  record  dates for the  determination  of holders to whom
interest is payable on any such interest  payment dates;  (7) the right, if any,
to extend the interest  payment periods and the duration of such extension;  (8)
provisions  for a sinking  purchase or other  analogous  fund,  if any;  (9) the
period or periods,  if any, within which,  the price or prices of which, and the
terms and  conditions  upon  which  such  Subordinated  Debt  Securities  may be
redeemed, in whole or in part, at the option of UDS or the holder; (10) the form
of such Subordinated  Debt Securities;  and (11) any other specific terms of the
Subordinated Debt Securities.  Principal, premium, if any, and interest, if any,
will be payable,  and the  Subordinated  Debt Securities  offered hereby will be
transferable, at the corporate trust office of the Debt Trustee in New York, New
York,  provided  that payment of interest,  if any, may be made at the option of
UDS by check mailed to the address of the person entitled  thereto as it appears
in the Security Register. (Section 307)

     If a Prospectus  Supplement  specifies that a series of  Subordinated  Debt
Securities  is  denominated  in a currency  or  currency  unit other than United
States dollars,  such Prospectus  Supplement shall also specify the denomination
in which  such  Subordinated  Debt  Securities  will be  issued  and the coin or
currency in which the principal,  premium, if any, and interest, if any, on such
Subordinated Debt Securities will be payable, which may be United States dollars
based upon the exchange  rate for such other  currency or currency unit existing
on or about the time a payment is due.

     The  Subordinated  Indenture  contains no covenants or other  provisions to
afford protection to holders of the Subordinated Debt Securities in the event of
a highly  leveraged  transaction  or a change in control  of UDS,  except to the
limited  extent  described  under  "Limitation  on Mergers  and Sales of Assets"
below.

Form, Exchange, Registration, Transfer and Payment

     Unless otherwise  specified in the applicable  Prospectus  Supplement,  the
Subordinated  Debt  Securities  will be issued in fully  registered form without
coupons  and in  denominations  of $1,000 and  multiples  of $1,000.  No service
charge  will be made for any  transfer  or  exchange  of the  Subordinated  Debt
Securities,  but UDS or the Debt Trustee may require payment of a sum sufficient
to cover any tax or other  government  charge  payable in connection  therewith.
Where  Subordinated Debt Securities of any series are issued in bearer form, the
special restrictions and considerations, including special offering restrictions
and special United States federal income tax  considerations,  applicable to any
such Subordinated Debt Securities and to payment on and transfer and exchange of
such Subordinated Debt Securities will be described in the applicable Prospectus
Supplement.  Bearer  Subordinated  Debt  Securities  will  be  transferrable  by
delivery.

     Unless  otherwise  provided  in  the  applicable   Prospectus   Supplement,
principal  and  premium,  if any, or interest,  if any,  will be payable and the
Subordinated  Debt  Securities may be surrendered  for payment or transferred at
the offices of the Debt  Trustee as paying and  authenticating  agent,  provided
that payment of interest on registered  securities  may be made at the option of
UDS by check mailed to the address of the person entitled  thereto as it appears
in the Security Register. Payment of Subordinated Debt Securities in bearer form
will be made at such  paying  agencies  outside of the United  States as UDS may
appoint.

Book-entry Subordinated Debt Securities
The  Subordinated  Debt Securities of a series may be issued in whole or in part
in the form of one or more Global  Securities that will be deposited with, or on
behalf of, a depositary (the "Global Depositary"), or its nominee, identified in
the Prospectus  Supplement  relating to such series. In such a case, one or more
Global  Securities  will be issued in a denomination  or aggregate  denomination
equal  to  the  portion  of  the  aggregate   principal  amount  of  Outstanding
Subordinated  Debt  Securities  of the series to be  represented  by such Global
Security or Securities. Unless and until it is exchanged in whole or in part for
Subordinated  Debt Securities in definitive  registered  form, a Global Security
may not be registered  for transfer or exchange  except as a whole by the Global
Depositary for such Global Security to a nominee for such Global  Depositary and
except in the circumstances described in the applicable Prospectus Supplement.

     The  specific  terms of the  depositary  arrangement  with  respect  to any
portion of a series of  Subordinated  Debt  Securities  to be  represented  by a
Global  Security and a description of the Global  Depositary will be provided in
the applicable Prospectus Supplement.

Subordination

     The  Subordinated  Debt Securities will be subordinated and junior in right
of payment to certain other  indebtedness  of UDS to the extent set forth in the
applicable Prospectus Supplement.

     If  Subordinated  Debt Securities are issued to UDS Capital II or a trustee
of such trust in connection with the issuance of Trust Securities by UDS Capital
II and (i) there shall have occurred any event that would constitute an Event of
Default (as defined  herein) or (ii) UDS shall be in default with respect to its
payment  of  any  obligations  under  the  related  Trust  Guarantee  or  Common
Securities  Guarantee,  then (a) UDS shall not declare or pay any  dividend  on,
make  any  distributions  with  respect  to,  or  redeem,  purchase  or  make  a
liquidation  payment with  respect to, any of its capital  stock (other than (i)
purchases or  acquisitions  of shares of UDS Common Stock in connection with the
satisfaction by UDS of its obligations  under any employee  benefit plans or the
satisfaction  by UDS of its  obligations  pursuant  to any  contract or security
requiring UDS to purchase  shares of UDS Common  Stock,  or (ii) the purchase of
fractional  interests  in  shares  of  UDS  capital  stock  as  a  result  of  a
reclassification of UDS capital stock or the exchange or conversion of one class
or series of UDS capital stock for another class or series of UDS capital stock)
or make any guarantee payments with respect to the foregoing,  and (b) UDS shall
not make any payment of  interest,  principal  or premium,  if any, on or repay,
repurchase or redeem any debt securities  (including  guarantees)  issued by UDS
which rank pari passu with or junior to such Subordinated Debt Securities.

     If  Subordinated  Debt Securities are issued to UDS Capital II or a trustee
of such trust in connection with the issuance of Trust Securities by UDS Capital
II and UDS shall have given notice of its election to defer payments of interest
on such Subordinated Debt Securities by extending the interest payment period as
provided  in the  Subordinated  Indenture  and  such  period,  or any  extension
thereof, shall be continuing, then (a) UDS shall not declare or pay any dividend
on,  make any  distributions  with  respect  to, or redeem,  purchase  or make a
liquidation payment with respect to, any of its capital stock, and (b) UDS shall
not make any payment of  interest,  principal  or premium,  if any, on or repay,
repurchase or redeem any debt securities  (including  guarantees)  issued by UDS
which rank pari passu with or junior to such Subordinated Debt Securities.

     In the event Subordinated Debt Securities are issued to UDS Capital II or a
trustee of such trust in connection with the issuance of Trust Securities of UDS
Capital II, for so long as such Trust Securities  remain  outstanding,  UDS will
covenant (i) to directly or  indirectly  maintain  100%  ownership of the Common
Securities of UDS Capital II; provided, however, that any permitted successor of
UDS under the  Subordinated  Indenture  may succeed to UDS's  ownership  of such
Common  Securities,  (ii) to use its reasonable  efforts to cause UDS Capital II
(a) to  remain  a  statutory  business  trust,  except  in  connection  with the
distribution of Subordinated  Debt Securities to the holders of Trust Securities
in liquidation of UDS Capital II, the redemption of all of the Trust  Securities
of UDS Capital II, or certain mergers, consolidations or amalgamations,  each as
permitted by the  Declaration  of UDS Capital II, and (b) to otherwise  continue
not to be classified as an  association  taxable as a corporation or partnership
for United States  federal  income tax purposes and (iii) to use its  reasonable
efforts  to cause  each  holder of Trust  Securities  to be treated as owning an
undivided beneficial interest in the Subordinated Debt Securities.

Limitation  on Mergers and Sales of Assets UDS shall not  consolidate  with,  or
merge into,  any  corporation  or convey or transfer its  properties  and assets
substantially  as an entirety to any Person unless the successor entity shall be
a corporation  organized under the laws of the United States or any State or the
District of Columbia and shall expressly assume the obligations of UDS under the
Subordinated Indenture. (Section 801)

Events of Default, Waiver and Notice

     The Subordinated  Indenture  provides than any one or more of the following
described  events which has occurred and is continuing  constitutes an "Event of
Default" with respect to each series of Subordinated Debt Securities:

period by UDS shall not constitute a default in the payment of interest for this
purpose; or

     (b)  default  in  payment  of  principal  and  premium,   if  any,  on  the
Subordinated  Debt  Securities of that series when due either at maturity,  upon
redemption,  by  declaration  or  otherwise;  provided,  however,  that a  valid
extension  of the  maturity  of such  Subordinated  Debt  Securities  shall  not
constitute a default for this purpose; or

     (c)  default by UDS in the  performance  of any other of the  covenants  or
agreements in the Subordinated  Indenture which shall not have been remedied for
a period of 90 days after notice; or

Securities)  if the Trustee  considers  it in the interest of such holders to do
so. (Section 5.08).

     The Subordinated Indenture provides that, (a) if an Event of Default due to
the default in the  payment of  principal,  interest or premium,  if any, on any

Subordinated Debt Securities of all series affected thereby then outstanding may
declare the  principal of all such  Subordinated  Debt  Securities to be due and
payable  immediately,  and (b) if an Event of Default  resulting from default in
the performance of any other of the covenants or agreements in the  Subordinated
Indenture or certain events of bankruptcy,  insolvency and reorganization of UDS
shall have occurred and be continuing, either the Debt Trustee or the holders of
25  percent  in  principal  amount  of all  Subordinated  Debt  Securities  then
outstanding (treated as one class) may declare the principal of all Subordinated
Debt Securities to be due and payable  immediately,  but upon certain conditions
such  declarations  may be  annulled  and past  defaults  may be waived  (except
defaults in payment of principal  of or interest or premium on the  Subordinated
Debt  Securities)  by the  holders  of a  majority  in  principal  amount of the
Subordinated  Debt Securities of such series (or of all series,  as the case may
be) then outstanding. (Section 5.01)

     The  holders of a majority in  principal  amount of the  Subordinated  Debt
Securities of any and all series  affected and then  outstanding  shall have the
right to direct the time,  method and place of conducting any proceeding for any
remedy available to the Debt Trustee under the Subordinated Indenture,  provided
that the holders of the  Subordinated  Debt Securities shall have offered to the
Debt Trustee  reasonable  indemnity against expenses and liabilities.  (Sections
5.07 and 5.04)

     The Subordinated  Indenture contains provisions permitting UDS and the Debt
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
principal amount of the  Subordinated  Debt Securities of all series affected by
such modification at the time outstanding,  to modify the Subordinated Indenture
or any supplemental  Subordinated  Indenture or the rights of the holders of the
Subordinated  Debt  Securities;  provided  that no such  modification  shall (i)

any holder of  Subordinated  Debt  Securities to institute  suit for the payment
thereof or the right of prepayment, if any, at the option of the holder, without
the  consent of the holder of each  Security  so  affected,  or (ii)  reduce the

Preferred  Security and any requirement for the approval by the holders of Trust
Preferred Securities, or of Trust Preferred Securities issued by UDS Capital II,
as a condition to  specified  action or  amendments  to the  Declaration  of UDS
Capital II;  (viii) the terms and  conditions,  if any, upon which the assets of
UDS Capital II may be distributed to holders of Trust Preferred Securities; (ix)
if applicable, any securities exchange upon which the Trust Preferred Securities
shall be listed;  and (x) any other relevant  rights,  preferences,  privileges,
limitations or restrictions of Trust Preferred  Securities issued by UDS Capital
II not  inconsistent  with the  Declaration of UDS Capital II or with applicable
law. All Trust Preferred  Securities offered hereby will be guaranteed by UDS to
the extent set forth  below under  "Description  of the Trust  Guarantees."  Any
United States  federal income tax  considerations  applicable to any offering of
Trust  Preferred  Securities  will be  described  in the  Prospectus  Supplement
relating thereto.

     In connection with the issuance of Trust Preferred Securities,  UDS Capital
II will issue one series of Common Securities. The Declaration of UDS Capital II
authorizes the Regular  Trustees of such trust to issue on behalf of UDS Capital
II one series of Common  Securities  having such terms including  distributions,
redemption,  voting,  liquidation  rights or such  restrictions  as shall be set
forth therein.  The terms of the Common Securities issued by UDS Capital II will
be substantially identical to the terms of the Trust Preferred Securities issued
by such trust and the Common  Securities will rank pari passu, and payments will
be made thereon pro rata, with the Trust Preferred  Securities except that, upon
an event of default  under the  Declaration,  the  rights of the  holders of the
Common  Securities  to payment in respect of  distributions  and  payments  upon
liquidation,  redemption and otherwise will be subordinated to the rights of the
holders  of  the  Trust   Preferred   Securities.   Except  in  certain  limited
circumstances,  the  Common  Securities  will  also  carry  the right to vote to
appoint,  remove or replace any of the UDS  Capital  Trustees of UDS Capital II.
All of the Common  Securities  of UDS Capital II will be directly or  indirectly
owned by UDS.

                       DESCRIPTION OF THE TRUST GUARANTEES

     Set forth below is a summary of information concerning the Trust Guarantees
which will be executed and  delivered by UDS for the benefit of the holders from
time to  time of  Trust  Preferred  Securities.  Each  Trust  Guarantee  will be
qualified as an indenture  under the Trust  Indenture  Act. The Bank of New York
will act as  indenture  trustee  under  each  Trust  Guarantee  (the  "Preferred
Guarantee  Trustee").  The terms of each Trust Guarantee will be those set forth
in such Trust Guarantee and those made part of such Trust Guarantee by the Trust
Indenture Act. The summary does not purport to be complete and is subject in all
respects to the provisions of, and is qualified in its entirety by reference to,
the form of Trust  Guarantee,  which is filed as an exhibit to the  Registration
Statement of which this  Prospectus  forms a part, and the Trust  Indenture Act.
Each Trust  Guarantee  will be held by the Preferred  Guarantee  Trustee for the
benefit of the holders of the Trust Preferred Securities of UDS Capital II.

General

     Pursuant to each Trust Guarantee,  UDS will irrevocably and unconditionally
agree,  to the extent set forth  therein,  to pay in full, to the holders of the
Trust  Preferred  Securities  issued by UDS  Capital  II,  the  Trust  Guarantee
Payments (as defined  herein)  (except to the extent paid by UDS Capital II), as
and when due, regardless of any defense,  right of set-off or counterclaim which
UDS Capital II may have or assert.  The following payments with respect to Trust
Preferred  Securities  issued by UDS  Capital  II to the  extent not paid by UDS
Capital  II (the  "Trust  Guarantee  Payments"),  will be  subject  to the Trust
Guarantee   thereon   (without   duplication):   (i)  any   accrued  and  unpaid
distributions which are required to be paid on such Trust Preferred  Securities,
to the extent UDS  Capital II shall  have  funds  available  therefor;  (ii) the
redemption  price,   including  all  accrued  and  unpaid   distributions   (the
"Redemption  Price"),  to the extent UDS Capital II has funds available therefor
with respect to any Trust  Preferred  Securities  called for  redemption  by UDS
Capital II and (iii) upon a voluntary or involuntary dissolution, winding-up, or
termination of UDS Capital II (other than in connection with the distribution of
the assets of UDS Capital II to the holders of Trust Preferred Securities or the
redemption  of all of the Trust  Preferred  Securities),  the  lesser of (a) the
aggregate of the liquidation amount and all accrued and unpaid  distributions on
such  Trust  Preferred  Securities  to the date of  payment,  to the  extent UDS
Capital  II has funds  available  therefor  and (b) the  amount of assets of UDS
Capital  II  remaining  available  for  distribution  to  holders  of such Trust
Preferred  Securities in liquidation of UDS Capital II. UDS's obligation to make
a Trust  Guarantee  Payment may be satisfied  by direct  payment of the required
amounts by UDS to the holders of Trust  Preferred  Securities  or by causing UDS
Capital II to pay such amounts to such holders.

     Each  Trust  Guarantee  will be a full  and  unconditional  guarantee  with
respect to the Trust Preferred Securities issued by UDS Capital II, but will not
apply to any payment of distributions  except to the extent UDS Capital II shall
have funds  available  therefor.  If UDS does not make interest  payments on the
Subordinated  Debt  Securities  purchased  by UDS  Funding II,  L.P.,  or if UDS
Funding  II,  L.P.  does not make  distributions  on the  Partnership  Preferred
Securities   purchased   by  UDS  Capital  II,  UDS  Capital  II  will  not  pay
distributions  on the Trust  Preferred  Securities  issued by UDS Capital II and
will not have funds available  therefor.  See  "Description of the  Subordinated
Debt  Securities  -- Certain  Covenants"  and  "Description  of the  Partnership
Preferred Securities."

     UDS has also agreed separately to irrevocably and unconditionally guarantee
the  obligations  of UDS Capital II with respect to the Common  Securities  (the
"Common  Securities  Guarantees")  to the same  extent as the Trust  Guarantees,
except that upon an event of default under the Subordinated  Indenture,  holders
of Trust  Preferred  Securities  shall  have  priority  over  holders  of Common
Securities with respect to distributions and payments on liquidation, redemption
or otherwise.

Certain Covenants of UDS

     In each  Trust  Guarantee,  UDS will  covenant  that,  so long as any Trust
Preferred Securities issued by UDS Capital II remain outstanding, if there shall
have  occurred any event that would  constitute  an event of default  under such
Trust  Guarantee  or the  Declaration  of UDS Capital II, then (a) UDS shall not
declare or pay any  dividend  on,  make any  distributions  with  respect to, or
redeem, purchase or make liquidation payment with respect to, any of its capital
stock (other than (i) purchases or acquisitions of shares of UDS Common Stock in
connection with the  satisfaction  by UDS of its obligations  under any employee
benefit  plans or the  satisfaction  by UDS of its  obligations  pursuant to any
contract or security  requiring  UDS to purchase  shares of UDS Common Stock or,
(ii) the purchase of  fractional  interests in shares of UDS capital  stock as a
result of a reclassification  of UDS capital stock or the exchange or conversion
of one class or series of UDS capital  stock for another  class or series of UDS
capital stock or make any  guarantee  payments with respect to the foregoing and
(b) UDS shall not make any payment of interest, principal or premium, if any, on
or repay, repurchase or redeem any debt securities (including guarantees) issued
by UDS  which  rank  pari  passu  with  or  junior  to  such  Subordinated  Debt
Securities.

Modification of the Trust Guarantees; Assignment

     Except with respect to any changes which do not adversely affect the rights
of  holders  of  Trust  Preferred  Securities  (in  which  case no vote  will be
required),  each Trust  Guarantee may be amended only with the prior approval of
the holders of not less than a majority in liquidation amount of the outstanding
Trust Preferred Securities issued by UDS Capital II. The manner of obtaining any
such approval of holders of such Trust Preferred Securities will be as set forth
in  an  accompanying  Prospectus  Supplement.   All  guarantees  and  agreements
contained in a Trust Guarantee shall bind the  successors,  assigns,  receivers,
trustees  and  representatives  of UDS and  shall  inure to the  benefit  of the
holders of the Trust Preferred Securities of UDS Capital II then outstanding.

Termination

     Each Trust  Guarantee will terminate as to the Trust  Preferred  Securities
issued by UDS Capital II (a) upon full  payment of the  Redemption  Price of all
Trust  Preferred  Securities  of UDS  Capital II, (b) upon  distribution  of the
assets of UDS Capital II to the holders of the Trust Preferred Securities of UDS
Capital II or (c) upon full payment of the amounts  payable in  accordance  with
the Declaration of UDS Capital II upon liquidation of UDS Capital II. Each Trust
Guarantee will continue to be effective or will be  reinstated,  as the case may
be,  if at any time any  holder  of Trust  Preferred  Securities  issued  by UDS
Capital II must  restore  payment  of any sums paid  under such Trust  Preferred
Securities or such Trust Guarantee.

Events of Default

     An event of default under a Trust  Guarantee will occur upon the failure of
UDS to perform any of its payment or other obligations thereunder.

     The  holders of a majority  in  liquidation  amount of the Trust  Preferred
Securities  relating to such Trust  Guarantee have the right to direct the time,
method and place of conducting any  proceeding  for any remedy  available to the
Preferred  Guarantee  Trustee in respect of the Trust Guarantee or to direct the
exercise of any trust or power  conferred upon the Preferred  Guarantee  Trustee
under such Trust Preferred Securities.  If the Preferred Guarantee Trustee fails
to  enforce  such Trust  Guarantee,  any  holder of Trust  Preferred  Securities
relating  to such Trust  Guarantee  may  institute a legal  proceeding  directly
against UDS to enforce the Preferred Guarantee Trustee's rights under such Trust
Guarantee,  without first instituting a legal proceeding against UDS Capital II,
the Preferred  Guarantee Trustee or any other person or entity.  Notwithstanding
the foregoing,  if UDS has failed to make a guarantee payment, a holder of Trust
Preferred  Securities  may  directly  institute  a  proceeding  against  UDS for
enforcement  of the Trust  Guarantee for such  payment.  UDS waives any right or
remedy to require that any action be brought first against UDS Capital II or any
other person or entity before proceeding directly against UDS.

Status of the Trust Guarantees

     The Trust Guarantees will constitute unsecured  obligations of UDS and will
rank (i) subordinate and junior in right of payment to all other  liabilities of
UDS, (ii) pari passu with the most senior  preferred or preference  stock now or
hereafter issued by UDS and with any guarantee now or hereafter  entered into by
UDS in respect of any preferred or preference stock of any affiliate of UDS; and
(iii) senior to UDS's common stock. The terms of the Trust Preferred  Securities
provide that each holder of Trust Preferred  Securities issued by UDS Capital II
by acceptance thereof agrees to the subordination  provisions and other terms of
the Trust Guarantee relating thereto.

     The Trust  Guarantees  will  constitute  a guarantee  of payment and not of
collection  (that is, the  guaranteed  party may  institute  a legal  proceeding
directly  against the guarantor to enforce its rights under the Trust  Guarantee
without instituting a legal proceeding against any other person or entity).

Information Concerning the Trust Guarantee Trustee

     The Trust  Guarantee  Trustee,  prior to the  occurrence  of a default with
respect to a Trust  Guarantee,  undertakes  to perform  only such  duties as are
specifically  set  forth in such  Trust  Guarantee  and,  after  default,  shall
exercise the same degree of care as a prudent  individual  would exercise in the
conduct  of his or her own  affairs.  Subject  to  such  provisions,  the  Trust
Guarantee Trustee is under no obligation to exercise any of the powers vested in
it by a  Trust  Guarantee  at the  request  of any  holder  of  Trust  Preferred
Securities,  unless offered reasonable indemnity against the costs, expenses and
liabilities which might be incurred thereby.

     UDS and certain of its  affiliates may from time to time maintain a banking
relationship with the Trust Guarantee Trustee.

Governing Law

     The Trust  Guarantees  will be governed by and construed in accordance with
the internal laws of the State of New York.

               DESCRIPTION OF THE PARTNERSHIP PREFERRED SECURITIES

     All of the  partnership  interests in UDS Funding II, L.P.,  other than the
Partnership  Preferred  Securities  acquired  by UDS  Capital  II, will be owned
directly by UDS. Initially,  UDS will be the sole General Partner of UDS Funding
II, L.P. The Limited  Partnership  Agreement of UDS Funding II, L.P.  authorizes
and  creates the  Partnership  Preferred  Securities,  which  represent  limited
partner  interests  in UDS  Funding  II,  L.P.  The  limited  partner  interests
represented by the Partnership  Preferred Securities will have a preference with
respect to  distributions  and amounts payable on redemption or liquidation over
the General  Partner's  interest in UDS  Funding  II, L.P.  Except as  otherwise
described  in the  applicable  Prospectus  Supplement,  the Limited  Partnership
Agreement of UDS Funding II, L.P. does not permit the issuance of any additional
partnership interests,  or the incurrence of any indebtedness by UDS Funding II,
L.P.  The  Partnership  Preferred  Securities  will have such  terms,  including
distributions,  redemption, voting, liquidation rights and such other preferred,
deferred,  or other special rights or such restrictions as shall be set forth in
the  Limited  Partnership  Agreement  or made  part of the  Limited  Partnership
Agreement by the Partnership Act. Reference is made to the Prospectus Supplement
relating to the  Partnership  Preferred  Securities  of UDS Funding II, L.P. for
specific terms,  including (i) the distinctive  designation of such  Partnership
Preferred Securities; (ii) the number of Partnership Preferred Securities issued
by UDS  Funding  II,  L.P.;  (iii) the  annual  distribution  rate (or method of
determining  such  rate)  for  Partnership  Preferred  Securities  issued by UDS
Funding II, L.P.  and the date or dates upon which such  distributions  shall be
payable;  provided,  however,  that distributions on such Partnership  Preferred
Securities  shall be payable on a quarterly basis to holders of such Partnership
Preferred  Securities,  if, as and when declared by the General Partner, as of a
record date in each quarter during which such Partnership  Preferred  Securities
are outstanding;  (iv) whether distributions on Partnership Preferred Securities
issued  by UDS  Funding  II,  L.P.  shall  be  cumulative,  and,  in the case of
Partnership Preferred Securities having such cumulative distribution rights, the
date  or  dates  or  method  of  determining   the  date  or  dates  from  which
distributions on Partnership Preferred Securities issued by UDS Funding II, L.P.
shall be  cumulative;  (v) the amount or amounts  which shall be paid out of the
assets  of  UDS  Funding  II,  L.P.  to the  holders  of  Partnership  Preferred
Securities of UDS Funding II, L.P. upon  voluntary or  involuntary  dissolution,
winding-up or termination of UDS Funding II, L.P.; (vi) the obligation,  if any,
of UDS Funding II, L.P. to purchase or redeem Partnership  Preferred  Securities
issued by UDS Funding II, L.P.  and the price or prices at which,  the period or
periods  within  which,  and the terms and  conditions  upon which,  Partnership
Preferred  Securities  issued by UDS  Funding  II, L.P.  shall be  purchased  or
redeemed,  in whole or in part,  pursuant to such  obligation;  (vii) the voting
rights,  if any, of Partnership  Preferred  Securities issued by UDS Funding II,
L.P.  in addition to those  required by law,  including  the number of votes per
Partnership  Preferred  Security,  any rights to appoint and authorize a special
representative (a "Special  Representative")  of UDS Funding II, L.P. to enforce
the  rights of the  holders  of  Partnership  Preferred  Securities  in  certain
situations  and any  requirement  for the approval by the holders of Partnership
Preferred Securities issued by UDS Funding II, L.P., as a condition to specified
action or  amendments  to the Limited  Partnership  Agreement of UDS Funding II,
L.P.;  (viii)  the terms and  conditions,  if any,  upon which the assets of UDS
Funding  II,  L.P.  may be  distributed  to  holders  of  Partnership  Preferred
Securities;   (ix)  if  applicable,  any  securities  exchange  upon  which  the
Partnership  Preferred  Securities  shall be listed;  and (x) any other relevant
rights,  preferences,  privileges,  limitations or  restrictions  of Partnership
Preferred  Securities  issued by UDS Funding II, L.P. not inconsistent  with the
Limited  Partnership  Agreement of UDS Funding II, L.P. or with  applicable law.
All Partnership Preferred Securities offered hereby will be guaranteed by UDS to
the extent set forth below under  "Description of the  Partnership  Guarantees."
Any United States federal income tax  considerations  applicable to any offering
of  Partnership  Preferred  Securities  will  be  described  in  the  Prospectus
Supplement relating thereto.

                    DESCRIPTION OF THE PARTNERSHIP GUARANTEES

     Set forth  below is a summary of  information  concerning  the  Partnership
Guarantees  which will be executed  and  delivered by UDS for the benefit of the
holders from time to time of Partnership Preferred Securities.  The summary does
not purport to be complete and is subject in all respects to the  provisions of,
and is  qualified  in its  entirety  by  reference  to, the form of  Partnership
Guarantee,  which is filed as an exhibit to the Registration  Statement of which
this  Prospectus  forms a part. Each  Partnership  Guarantee will be held by the
General  Partner of UDS Funding  II, L.P.  for the benefit of the holders of the
Partnership Preferred Securities of UDS Funding II, L.P.

General

     Pursuant  to  each   Partnership   Guarantee,   UDS  will  irrevocably  and
unconditionally  agree, to the extent set forth therein,  to pay in full, to the
holders of the Partnership  Preferred Securities issued by UDS Funding II, L.P.,
the  Partnership  Guarantee  Payments (as defined  herein) (except to the extent
paid by UDS Funding II, L.P.), as and when due, regardless of any defense, right
of set-off or  counterclaim  which UDS Funding II, L.P. may have or assert.  The
following  payments with respect to Partnership  Preferred  Securities issued by
UDS  Funding  II,  L.P.  to the extent not paid by UDS  Funding  II,  L.P.  (the
"Partnership Guarantee Payments"),  will be subject to the Partnership Guarantee
thereon (without  duplication):  (i) any accrued and unpaid  distributions  that
have  been  declared  on such  Partnership  Preferred  Securities,  out of Funds
legally available therefor; (ii) the redemption price, including all accrued and
unpaid  distributions (the "Redemption  Price"),  out of funds legally available
therefor  with  respect  to any  Partnership  Preferred  Securities  called  for
redemption by UDS Funding II, L.P. and (iii) upon a  liquidation  of UDS Funding
II,  L.P.,  the lesser of (a) the  aggregate of the  liquidation  amount and all
accrued and unpaid distributions on such Partnership Preferred Securities to the
date of payment,  and (b) the amount of assets of UDS Funding  II,  L.P.,  after
satisfaction of all liabilities, remaining available for distribution to holders
of such Partnership  Preferred Securities in liquidation of UDS Funding II, L.P.
UDS's  obligation  to make a Partnership  Guarantee  Payment may be satisfied by
direct  payment of the  required  amounts by UDS to the  holders of  Partnership
Preferred  Securities  or by causing UDS Funding II, L.P. to pay such amounts to
such holders.

     Each Partnership Guarantee will be a full and unconditional  guarantee with
respect to the Partnership  Preferred Securities issued by UDS Funding II, L.P.,
but will not apply to any payment of  distributions  or Redemption  Price, or to
payments upon the liquidation of UDS Funding II, L.P.,  except to the extent UDS
Funding  II,  L.P.  shall  have funds  legally  available  therefor.  If issuers
(including,  where applicable, UDS, as guarantor) of the securities in which UDS
Funding II, L.P. invests fail to make any payments in respect of such securities
(or, if  applicable,  guarantees),  UDS Funding II, L.P.  may not declare or pay
dividends on the  Partnership  Preferred  Securities  of UDS Funding II, L.P. In
such event,  holders of such Partnership  Preferred Securities would not be able
to rely upon the  Partnership  Guarantee for payment of such  amounts.  Instead,
holders of such  Partnership  Preferred  Securities  shall have certain remedies
described in the applicable Prospectus Supplement, including the right to direct
the  General  Partner  or the  Special  Representative,  as the case may be,  to
enforce the  covenant  restricting  certain  distributions  by UDS. See "Certain
Covenants of UDS" below.

Certain Covenants of UDS

     In  each  Partnership  Guarantee,   UDS  will  covenant  that  if  for  any
distribution  period,  (a)  full  distributions  on a  cumulative  basis  on any
Partnership  Preferred  Securities have not been paid or declared and set a part
for  payment,  (b) an event  of  default  by UDS or  certain  domestic  eligible
controlled  affiliates  in respect of any debt security in which UDS Funding II,
L.P.  invests has  occurred  and is  continuing  or (c) UDS is in default of its
obligations under the applicable Trust Guarantee,  Partnership  Guarantee or any
Investment Guarantee,  then, during such period (i) UDS shall not declare or pay
dividends  on,  make  distributions  with  respect  to, or redeem,  purchase  or
acquire,  or make a liquidation payment with respect to any of its capital stock
(except  for  dividends  or  distributions  in  shares of its  common  stock and
exchanges of common stock of one class for common stock of another class),  (ii)
UDS shall not make any payment or cause any payment to be made that would result
in, and shall take such action as shall be necessary to prevent,  the payment of
dividends  on, any  distribution  with respect to, any  redemption,  purchase or
other acquisition of, or any liquidation  payment with respect to, any preferred
security  hereafter  issued by any  finance  subsidiary  of UDS,  the  principal
purpose  of which  is to lend the  proceeds  of the  sale  thereof  to UDS or to
eligible  affiliates of UDS, and (iii) UDS shall not make any guarantee payments
with respect to the foregoing.

Modification of the Partnership Guarantees; Assignment

     Except with respect to any changes which do not adversely affect the rights
of holders of  Partnership  Preferred  Securities (in which case no vote will be
required),  each  Partnership  Guarantee  may be  amended  only  with the  prior
approval of the holders of not less than a majority in liquidation amount of the
outstanding  Partnership Preferred Securities issued by UDS Funding II, L.P. The
manner of obtaining any such approval of holders of such  Partnership  Preferred
Securities will be as set forth in an accompanying  Prospectus  Supplement.  All
guarantees and agreements  contained in a Partnership  Guarantee  shall bind the
successors,  assigns,  receivers,  trustees and representatives of UDS and shall
inure to the benefit of the holders of the Partnership  Preferred  Securities of
UDS Funding II, L.P. then outstanding.

Termination

Each  Partnership  Guarantee  will  terminate  as to the  Partnership  Preferred
Securities  issued  by UDS  Funding  II,  L.P.  (a)  upon  full  payment  of the
Redemption  Price of all  Partnership  Preferred  Securities  of UDS Funding II,
L.P.,  or (b) upon full payment of the amounts  payable in  accordance  with the
Limited  Partnership  Agreement of UDS Funding II, L.P. upon  liquidation of UDS
Funding II, L.P.  Each  Partnership  Guarantee  will continue to be effective or
will be reinstated, as the case may be, if at any time any holder of Partnership
Preferred  Securities issued by UDS Funding II, L.P. must restore payment of any
sums paid  under  such  Partnership  Preferred  Securities  or such  Partnership
Guarantee.  The  Partnership  Act provides  that a limited  partner of a limited
partnership who wrongfully  receives a distribution may be liable to the limited
partnership for the amount of such distribution.

Events of Default; Enforcement of Partnership Guarantee

     An event of  default  under a  Partnership  Guarantee  will  occur upon the
failure of UDS to perform any of its payment or other obligations thereunder.

     The  holders  of a  majority  in  liquidation  amount  of  the  Partnership
Preferred  Securities  relating to such Partnership  Guarantee have the right to
direct the time,  method and place of conducting  any  proceeding for any remedy
available to the Special  Representative in respect of the Partnership Guarantee
or to direct  the  exercise  of any trust or power  conferred  upon the  Special
Representative  under such  Guarantee.  If the Special  Representative  fails to
enforce  its  rights  under  such  Partnership  Guarantee,  after  a  holder  of
Partnership  Preferred  Securities  has made a written  request,  such holder of
Partnership  Preferred  Securities  relating to such  Partnership  Guarantee may
institute  a legal  proceeding  directly  against  UDS to  enforce  the  Special
Representative's   rights  under  such  Partnership  Guarantee,   without  first
instituting  a legal  proceeding  against  UDS  Funding  II,  L.P.,  the Special
Representative or any other person or entity.  Notwithstanding the foregoing, if
UDS has failed to make a Partnership  Guarantee Payment, a holder of Partnership
Preferred  Securities  may  directly  institute  a  proceeding  against  UDS for
enforcement of the Partnership Guarantee for such payment.

Status of the Partnership Guarantees

     The Partnership Guarantees will constitute unsecured obligations of UDS and
will  rank  (i)  subordinate  and  junior  in  right  of  payment  to all  other
liabilities of UDS, (ii) pari passu with the most senior preferred or preference
stock now or  hereafter  issued by UDS and with any  guarantee  now or hereafter
entered  into by UDS in  respect of any  preferred  or  preference  stock of any
affiliate  of UDS;  and (iii)  senior to UDS's  common  stock.  The terms of the
Partnership  Preferred  Securities  provide  that  each  holder  of  Partnership
Preferred Securities issued by UDS Funding II, L.P. by acceptance thereof agrees
to the  subordination  provisions and other terms of the  Partnership  Guarantee
relating thereto.

     The  Partnership  Guarantees will constitute a guarantee of payment and not
of collection  (that is, the guaranteed  party may institute a legal  proceeding
directly  against  the  guarantor  to enforce its rights  under the  Partnership
Guarantee  without  instituting a legal  proceeding  against any other person or
entity).

     Each  Partnership  Guarantee will be deposited with the General  Partner of
UDS  Funding  II,  L.P.  to be  held  for  the  benefit  or the  holders  of the
Partnership  Preferred  Securities  of UDS  Funding  II, L.P. In the event of an
appointment  of a Special  Representative  to,  among  other  things,  enforce a
Partnership  Guarantee,  the Special  Representative  may take possession of the
applicable  Partnership Guarantee for such purpose. If no Special Representative
has been appointed to enforce such  Partnership  Guarantee,  the General Partner
has the right to enforce such Partnership  Guarantee on behalf of the holders of
the Partnership Preferred Securities of UDS Funding II, L.P.

Governing Law

     The Partnership  Guarantees will be governed by and construed in accordance
with the internal laws of the State of New York.

                       DESCRIPTION OF CAPITAL STOCK OF UDS

     The following summary does not purport to be complete and is subject in all
respects to the applicable  provisions of the Delaware  General  Corporation Law
(the "DGCL"),  the certificate of  incorporation  of UDS (the "UDS Charter") and
the terms of the UDS Rights  Agreement  (as  defined  below  under  "UDS  Rights
Plan").

     UDS's  authorized  capital stock consists of  250,000,000  shares of common
stock (the "UDS Shares"), of which 86,662,761 shares were issued and outstanding
on December 31, 1997, and 25,000,000  preferred  shares, of which 1,724,400 were
issued and outstanding on December 31, 1997.

UDS Common Stock

     Dividend  Rights.  Holders of UDS Shares are entitled to receive  dividends
when,  as and if  declared  by the UDS  Board,  out of funds  legally  available
therefor,  subject, however, to the rights relating to any outstanding preferred
stock of UDS.

     Voting Rights.  Subject to the rights, if any, of the holders of any series
of preferred  stock of UDS,  all voting  rights are vested in the holders of UDS
Shares,  each share being  entitled to one vote on each matter  presented  for a
vote,  including  the  election of  directors.  The UDS Board,  which  currently
consists of 12 directors,  is divided into three  classes of directors  with the
term of one class  expiring  at each  annual  meeting of  stockholders.  Because
holders of UDS Shares do not have  cumulative  voting  rights,  the holders of a
plurality of the UDS Shares represented at a meeting can elect all the directors
standing for election at such meeting.

     Rights upon  Liquidation.  In the event of the liquidation,  dissolution or
winding up of UDS, whether  voluntary or involuntary,  the holders of UDS Shares
will be  entitled  to share  ratably in assets  available  for  distribution  to
holders  of  UDS  Shares,  subject,  however,  to  the  rights  relating  to any
outstanding preferred stock of UDS.

     Miscellaneous.  UDS Shares are not liable for further calls or  assessments
by UDS and the holders of UDS Shares are not liable for any  liabilities of UDS.
The UDS  Shares  do not  have  preemptive  or  other  subscription  rights,  any
conversion  rights,  or any redemption or sinking fund  provisions.  Registrar &
Transfer  Company and The R-M Trust Company act as transfer  agent and registrar
for the UDS Shares in the United States and Canada, respectively.

UDS Rights.  For a description of rights which are attached to each  outstanding
UDS Share, see "UDS Rights Plan."


UDS Preferred Stock

     The following  description  of the terms of the Preferred  Stock sets forth
certain  general  terms  and  provisions  of the  Preferred  Stock  to  which  a
Prospectus  Supplement  may relate.  Specific  terms of any series of  Preferred
Stock  offered by a Prospectus  Supplement  will be described in the  Prospectus
Supplement relating to such series of Preferred Stock. The description set forth
below is  subject to and  qualified  in its  entirety  by  reference  to the UDS
Charter  and  the  form  of  Certificate  of  Designations  (the  "Designation")
establishing a particular series of Preferred Stock which will be filed with the
Commission in connection with the offering of such series of Preferred Stock.

     General.  Under the UDS Charter, the Board of Directors of the Company (the
"Board of Directors") is authorized,  without  further  shareholder  action,  to
provide for the issuance of up to 25,000,000  shares of Preferred  Stock, in one
or more series,  and to fix the  designations,  terms,  and relative  rights and
preferences,  including the dividend  rate,  voting rights,  conversion  rights,
redemption,  and sinking fund  provisions  and  liquidation  values of each such
series.  UDS may amend the UDS Charter  from time to time to increase the number
of authorized  shares of Preferred  Stock.  Any such amendment would require the
approval of the holders of a majority of the outstanding shares of all series of
Preferred Stock voting  together as a single class without regard to series.  As
of the  date  of  this  Prospectus,  UDS  has  one  series  of  Preferred  Stock
outstanding.

     The  Preferred  Stock  will  have the  dividend,  liquidation,  redemption,
conversion,  and voting rights set forth below unless otherwise  provided in the
Prospectus  Supplement  relating  to a  particular  series of  Preferred  Stock.
Reference is made to the Prospectus Supplement relating to the particular series
of the Preferred Stock offered thereby for specified terms,  including,  (i) the
title  and  liquidation  preference  per share of such  Preferred  Stock and the
number of shares  offered;  (ii) the price at which such Preferred Stock will be
issued;  (iii) the dividend rate (or method of calculation),  the dates on which
dividends  shall be payable and the dates from which dividends shall commence to
accumulate;  (iv) any  redemption or sinking fund  provisions of such  Preferred
Stock; (v) any conversion or exchange  provisions of such Preferred Stock;  (vi)
the voting  rights,  if any, of such Preferred  Stock;  and (vii) any additional
dividend,  liquidation,  redemption, sinking fund and other rights, preferences,
privileges, limitations, and restrictions of such Preferred Stock. The Preferred
Stock will, when issued, be fully paid and nonassessable.

     Dividend  Rights.  The  Preferred  Stock will be preferred  over the Common
Stock as to payment of dividends.  Before any dividends or  distributions on the
Common Stock shall be declared and set apart for payment or paid, the holders of
shares of each series of Preferred Stock shall be entitled to receive  dividends
(either in cash,  shares of Common Stock or Preferred Stock, or otherwise) when,
as, and if  declared by the Board of  Directors,  at the rate and on the date or
dates as set forth in the Prospectus Supplement.  With respect to each series of
Preferred  Stock,  the  dividends  on each share of such series with  respect to
which  dividends are  cumulative  shall be cumulative  from the date of issue of
such share  unless  some other  date is set forth in the  Prospectus  Supplement
relating to any such series. Accruals of dividends shall not bear interest.

     Rights Upon  Liquidation.  The Preferred  Stock shall be preferred over the
Common Stock as to assets so that the holders of each series of Preferred  Stock
shall be entitled to be paid,  upon the  voluntary or  involuntary  liquidation,
dissolution  or winding up of UDS,  and before any  distribution  is made to the
holders  of Common  Stock,  the amount  set forth in the  Prospectus  Supplement
relating  to any such  series,  but in such case the  holders of such  series of
Preferred Stock shall not be entitled to any other or further  payment.  If upon
any such liquidation,  dissolution, or winding up of UDS its net assets shall be
insufficient  to permit the payment in full of the  respective  amounts to which
the  holders  of all  outstanding  Preferred  Stock  are  entitled,  the  entire
remaining  net  assets of UDS shall be  distributed  among the  holders  of each
series of Preferred Stock in amounts  proportionate to the full amounts to which
the holders of each such series are respectively so entitled.

     Redemption  and  Conversion.  All shares of any series of  Preferred  Stock
shall  be  redeemable  to the  extent  set  forth in the  Prospectus  Supplement
relating to any such series.  All shares of any series of Preferred  Stock shall
be convertible into shares of Common Stock or into shares of any other series of
Preferred Stock to the extent set forth in the Prospectus Supplement relating to
any such series.

     Voting Rights.  All shares of any series of Preferred  Stock shall have the
voting  rights  set  forth in the  Prospectus  Supplement  relating  to any such
series.

UDS Rights

     UDS has  entered  into a  rights  agreement  with  Registrar  and  Transfer
Company,  as rights agent.  Pursuant to the Rights Agreement,  a right initially
representing  the right to purchase  one UDS Share (a "UDS Right") at a price of
$75  (the  "UDS   Rights   Purchase   Price"),   exercisable   only  in  certain
circumstances, was issued with respect to each UDS Share outstanding on June 25,
1992 and will be issued with  respect to each UDS Share  issued by UDS until the
earliest of the UDS Distribution Date (as defined below),  the redemption of the
UDS Rights, or the UDS Rights Expiration Date (as defined below). UDS Rights may
also be issued with respect to UDS Shares issued after the UDS Distribution Date
in certain circumstances. Until a UDS Right is exercised, the holder thereof, as
such,  will  have  no  rights  as  a  stockholder  of  UDS,  including,  without
limitation, the right to vote or to receive dividends.

     Until the earlier of (i) such time as UDS learns that a person has become a
UDS Acquiring  Person (as defined  below) and (ii) the close of business on such
date, if any, as may be designated by the UDS Board  following the  commencement
of, or first public  disclosure  of an intent to commence,  a tender or exchange
offer by any person (subject to certain  exceptions) for outstanding UDS Shares,
if upon  consummation of such tender or exchange offer such person's  beneficial
ownership  of  outstanding  UDS  Shares  could  equal or  exceed  such  person's
Ownership Threshold (as defined below) (the earlier of such dates being the "UDS
Distribution  Date"),  the UDS Rights will be evidenced by the  certificates for
UDS Shares  registered  in the names of the holders  thereof and not by separate
right certificates.  Therefore,  until the UDS Distribution Date, the UDS Rights
will be transferred with and only with the UDS Shares.

     For  purposes  of the UDS  Rights  Agreement,  (i) the term "UDS  Acquiring
Person"  means,  subject  to  certain  exceptions  set  forth in the UDS  Rights
Agreement,  any person,  alone or together with all affiliates and associates of
such person,  whose  beneficial  ownership of  outstanding  UDS Shares equals or
exceeds  such  person's  Ownership   Threshold  and  (ii)  the  term  "Ownership
Threshold"  means,  with  respect to any  person,  beneficial  ownership  of the
greater of (a) 10% of the  outstanding  UDS Shares or (b) 3% plus the percentage
of the outstanding UDS Shares beneficially owned by such person on May 10, 1994.

     Pursuant  to its terms and with  certain  limited  exceptions,  the  Rights
Agreement  may be amended or  supplemented  by UDS without  the  approval of any
holder of UDS Rights.

     In the event a person becomes a UDS Acquiring  Person,  the UDS Rights will
entitle  each  holder  thereof  (other  than the UDS  Acquiring  Person  (or any
affiliate or associate of such UDS Acquiring  Person)) to purchase,  for the UDS
Rights Purchase Price, that number of UDS Shares equivalent to the number of UDS
Shares which at the time of the  transaction  would have a market value of twice
the UDS Rights Purchase Price. Any UDS Rights that are at any time  beneficially
owned  by a UDS  Acquiring  Person  (or  any  affiliate  or  associate  of a UDS
Acquiring  Person) will be null and void and  nontransferable  and any holder of
any such UDS Right  (including  any purported  transferee or subsequent  holder)
will be unable to exercise or transfer any such UDS Right.

     After there is a UDS Acquiring Person,  the UDS Board may elect to exchange
each UDS  Right  (other  than UDS  Rights  that  have  become  null and void and
nontransferable  as described above) for  consideration per UDS Right consisting
of  one-half  of the  securities  that would be  issuable  at such time upon the
exercise of one UDS Right pursuant to the terms of the UDS Rights Agreement, and
without payment of the UDS Rights Purchase Price.

     In the event that,  following a UDS Distribution Date, UDS is acquired in a
merger by, or other business  combination  with, or 50% or more of its assets or
assets representing 50% or more of its earning power are sold, leased, exchanged
or otherwise  transferred  (in one or more  transactions)  to, a publicly traded
corporation,   or  such  corporation  merges  with  and  into  UDS  (in  certain
circumstances),  each UDS Right will  entitle  its holder  (subject  to the next
paragraph) to purchase, for the UDS Rights Purchase Price, that number of common
shares of such  corporation  which at the time of the  transaction  would have a
market  value of twice  the UDS  Rights  Purchase  Price.  In the  event  UDS is
acquired in a merger by, or other business  combination  with, or 50% or more of
its assets or assets  representing  50% or more of the earning  power of UDS are
sold, leased,  exchanged or otherwise  transferred (in one or more transactions)
to an entity  that is not a  publicly  traded  corporation  or such  corporation
merges with and into UDS (in certain circumstances), each UDS Right will entitle
its holder  (subject  to the next  paragraph)  to  purchase,  for the UDS Rights
Purchase  Price,  at such  holder's  option,  (i) that  number of shares of such
entity  (or, at such  holder's  option,  of the  surviving  corporation  in such
acquisition, which could be UDS) which at the time of the transaction would have
a book value of twice the UDS Rights  Purchase  Price or (ii) if such entity has
an affiliate  which has publicly  traded  common  shares,  that number of common
shares  of such  affiliate  which at the time of the  transaction  would  have a
market value of twice the UDS Rights Purchase Price.

     The UDS Rights are not exercisable until the UDS Distribution Date and will
expire on July 6,  2002  (the  "UDS  Rights  Expiration  Date")  unless  earlier
redeemed or canceled by UDS as described below. At any time prior to the earlier
of (i) such time as a person  becomes an UDS  Acquiring  Person and (ii) the UDS
Rights  Expiration  Date, the UDS Board may redeem the UDS Rights in whole,  but
not in part, at a price (in cash or UDS Shares or other securities of UDS deemed
by the UDS Board to be at least  equivalent  in  value)  of $.01 per UDS  Right,
subject to adjustment as provided in the UDS Rights  Agreement  (the "UDS Rights
Redemption  Price");  provided  that, for the 120-day period after any date of a
change (resulting from a proxy or consent solicitation) in a majority of the UDS
Board in office at the  commencement  of such  solicitation,  the UDS Rights may
only be redeemed if (a) there are directors then in office who were in office at
the  commencement  of  such  solicitation  and  (b)  the  UDS  Board,  with  the
concurrence of a majority of such directors then in office, determines that such
redemption  is,  in  its  judgment,  in  the  best  interests  of  UDS  and  its
stockholders.  Immediately  upon the action of the UDS Board  electing to redeem
the UDS Rights,  the right to exercise the UDS Rights will  terminate and within
ten business days, UDS will give notice thereof to holders of UDS Rights.

The Delaware Business Combination Act

     Section 203 of the General  Corporation  Law of the State of Delaware  (the
"DGCL") imposes a three-year  moratorium on business  combinations  (as defined)
between a Delaware  corporation and an "interested  stockholder" (in general,  a
stockholder  owning 15 percent  or more of a  corporation's  outstanding  voting
stock) or an affiliate or associate  thereof  unless (a) prior to an  interested
stockholder  becoming such, the Board of Directors of the  corporation  approved
either the business  combination or the transaction  resulting in the interested
stockholder becoming such, (b) upon consummation of the transaction resulting in
an interested  stockholder  becoming such, the  interested  stockholder  owns at
least 85 percent of the voting  stock  outstanding  at the time the  transaction
commenced  (excluding,  from  the  calculation  of  outstanding  shares,  shares
beneficially owned by management, directors and certain employee stock plans) or
(c) on or after an interested stockholder becomes such, the business combination
is approved by (i) the board of  directors  and (ii)  holders of at least 66-2/3
percent of the outstanding shares (other than those shares beneficially owned by
the interested stockholder) at a meeting of stockholders.

     Business  combinations  include (a) mergers or  consolidations,  (b) sales,
leases,  exchanges or other  transfers  of ten percent or more of the  aggregate
assets of UDS, (c) issuance or transfers by the  corporation of any stock of the
corporation   which  would  have  the  effect  of  increasing   the   interested
stockholder's  proportionate  share of the  stock of any  class or series of the
corporation,  (d) any other  transaction  which has the effect of increasing the
proportionate share of the stock of any class or series of the corporation which
is  owned  by an  interested  stockholder  and  (e)  receipt  by  an  interested
stockholder of the benefit  (except  proportionately  as  stockholder) of loans,
advances, guarantees, or other financial benefits provided by the corporation.

Certain Provisions of the Certificate of Incorporation and By-laws

     The Certificate of Incorporation of UDS (the  "Certificate") and By-laws of
UDS (the "By-laws")  contain certain provisions that may delay, defer or prevent
a change in control of UDS and make removal of management of UDS more difficult.

     The Certificate provides that the Board of Directors of UDS is divided into
three classes that are elected for staggered  three-year  terms, with the number
of directors in each class to be as nearly  equal as possible.  The  Certificate
provides  that  stockholder  action  may be taken  only at an annual or  special
meeting  of  stockholders,  and may  not be  taken  by  written  consent  of the
stockholders.  The Certificate also provides that special meetings may be called
only by the Chairman of the Board,  if there be one, the  President or the Board
of Directors.

     The Certificate also contains certain "fair price  provisions"  designed to
provide safeguards for stockholders when an "interested stockholder" (defined as
a stockholder owning ten percent or more of UDS's voting stock) or its affiliate
or  associate  attempts to effect a "business  combination"  with UDS.  The term
"business combination" includes any merger or consolidation of UDS involving the
interested  stockholder,  certain dispositions of assets of UDS, any issuance of
securities  of  UDS,  meeting  certain  threshold  amounts,  to  the  interested
stockholder,  adoption of any plan of liquidation or dissolution of UDS proposed
by the  interested  stockholder  and any  reclassification  of securities of UDS
having the effect of  increasing  the  proportionate  share of  ownership of the
interested  stockholder.  In general, a business combination between UDS and the
interested  stockholder  must be approved by the affirmative  vote of 80% of the
outstanding  voting  stock,  excluding  voting  stock  owned by such  interested
stockholder,  unless the transaction is approved by a majority of the members of
the Board of Directors who are not affiliated with the interested stockholder or
certain minimum price and form of consideration  requirements are satisfied. See
also "The Delaware Business Combination Act."

     The By-laws  provide  that the Board of  Directors  shall fix the number of
directors and that a stockholder  may nominate  directors only if written notice
is delivered to UDS by such  stockholder 60 days in advance of an annual meeting
or  within  ten  days  after  the date of  notice  by UDS of a  special  meeting
involving the election of directors.  The By-laws and  Certificate  also provide
that any newly created directorship  resulting from an increase in the number of
directors or a vacancy on the Board shall be filled by vote of a majority of the
remaining directors then in office,  even, in the case of a vacancy other than a
newly created directorship,  if less than a quorum. A director elected to fill a
vacancy shall be elected for the unexpired term of his predecessor in office.  A
director  elected by reason of an increase in the number of  directors  shall be
elected  until the next election of one or more  directors by the  stockholders.
Directors  may be  removed  from  office  but  only  for  cause  and only by the
affirmative vote of a majority of the then outstanding  shares of stock entitled
to vote on the matter. "Cause" is defined in the Certificate to mean the "wilful
and continuous  failure of a director to  substantially  perform such director's
duties to the Corporation  (including any such failure resulting from incapacity
due to physical or mental illness) or the wilful engaging by a director in gross
misconduct  materially  and  demonstrably  injurious  to the  Corporation."  The
Certificate provides that the By-laws and Certificate may not be amended without
the  approval of at least 80% of the voting  power of all shares of UDS entitled
to vote  generally in the  election of  directors,  voting  together as a single
class.

     The foregoing  provisions,  together with the ability of the Board to issue
Preferred Stock without further stockholder action, could delay or frustrate the
removal of incumbent  directors or the  assumption of control by the holder of a
large block of UDS's Common Stock even if such  removal or  assumption  would be
beneficial, in the short term, to stockholders of UDS. The provisions could also
discourage or make more  difficult a merger,  tender offer or proxy contest even
if such event would be favorable to the interests of stockholders.

                              PLAN OF DISTRIBUTION

     UDS may sell the Senior Debt Securities,  the Subordinated Debt Securities,

Funding II, L.P.,  and/or UDS Capital II will execute an underwriting  agreement
with  such  underwriters  at the  time  of sale to  them  and the  names  of the

Prospectus  Supplement,  which will be used by the underwriters to make releases
of the Offered  Securities  in respect of which this  Prospectus is delivered to
the public.

     If a dealer is utilized in the sale of the Offered Securities in respect of
which this Prospectus is delivered, UDS, UDS Funding II, L.P. and/or UDS Capital
II, as the case may be, will sell such  Offered  Securities  to the  dealer,  as
principal.  The dealer may then resell such Offered  Securities to the public at
varying  prices to be determined by such dealer at the time of resale.  The name
of the  dealer  and  the  terms  of the  transaction  will be set  forth  in the
Prospectus Supplement.

     Agents,  underwriters,  and  dealers  may be  entitled  under the  relevant
agreements to  indemnification  by UDS, UDS Funding II, L.P.  and/or UDS Capital
II, as the case may be, against certain liabilities, including liabilities under
the Securities Act of 1933.

     The place and time of  delivery  for the Offered  Securities  in respect of
which this Prospectus is delivered are set forth in the accompanying  Prospectus
Supplement.

Item 15.  Indemnification of Directors and Officers.

     The By-Laws of the Registrant  provide that the Registrant  shall indemnify
its officers and directors to the fullest  extent  permitted by applicable  law.
Section 145 of the Delaware General  Corporation Law (the "DGCL")  provides,  in
general,  that each  director and officer of a  corporation  may be  indemnified
against expenses (including attorneys' fees,  judgments,  fines and amounts paid
in settlement)  actually and reasonably  incurred in connection with the defense
or settlement of any threatened, pending or completed legal proceedings in which
he is involved by reason of the fact that he is or was a director or officer, if
he acted in good faith and in a manner that he  reasonably  believed to be in or
not opposed to the best  interest of the  corporation,  and, with respect to any
criminal action or proceeding, if he had no reasonable cause to believe that his
conduct was unlawful. If the legal proceeding, however, is by or in the right of
the  corporation,  the director or officer may not be  indemnified in respect of
any claim,  issue or matter as to which he shall have been adjudged to be liable
for  negligence  or misconduct  in the  performance  of his duty to UDS unless a
court determines otherwise.

     The  Certificate  of  Incorporation  of the  Registrant  provides  that the
personal liability of the directors of the Registrant shall be eliminated to the
fullest  extent  permitted by applicable  law. The DGCL permits a  corporation's
certificate  of  incorporation  to provide  that no director of the  corporation
shall be personally  liable to the corporation or its  stockholders for monetary
damages for any breach of his fiduciary duty as a director;  provided,  however,
that such  provision  shall not apply to any liability of a director (1) for any
breach of a director's duty of loyalty to the  corporation or its  stockholders,
(2) for acts or  omissions  that are not in good  faith or  involve  intentional
misconduct or a knowing  violation of the law, (3) under Section 174 of the DGCL
or (4) for any transaction from which the director derived an improper  personal
benefit.

     Pursuant to their employment  agreements with the Registrant,  Messrs. Jean
Gaulin and H. Pete Smith are indemnified from all liabilities arising out of the
activities reasonably taken in the performance of their duties.

     The Registrant also maintains  insurance for officers and directors against
certain liabilities, including liabilities under the Securities Act of 1933. The
effect  of this  insurance  is to  indemnify  any  officer  or  director  of the
Registrant against expenses,  including,  without  limitation,  attorneys' fees,
judgments,  fines and  amounts  paid in  settlement,  incurred  by an officer or
director upon a determination that such person acted in good faith. The premiums
for such insurance are paid by the Registrant.

     The above  discussion  of the  Registrant's  By-laws,  its  Certificate  of
Incorporation,  its  employment and the DGCL is not intended to be exclusive and
is  respectively  qualified  in its  entirety by such  By-laws,  Certificate  of
Incorporation, employment agreements, and statute.

Item 17.   Undertakings.

     A.   Undertaking Pursuant to Rule 415.

     The Registrants hereby undertake:

     (1) To file,  during any period in which  offers or sales are being made, a
post-effective amendment to this Registration Statement:

     (i)  to  include  any  prospectus  required  by  Section  10(a)(3)  of  the
Securities Act of 1933 (the "Securities Act");

     (ii) to reflect in the  prospectus  any facts or events  arising  after the
effective date of the Registration  Statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental  change in the information set forth in the Registration  Statement;
notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  end of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20% change in the maximum
aggregate  offering price set forth in the  "Calculation  of  Registration  Fee"
table in the effective registration statement; and

     (iii) to  include  any  material  information  with  respect to the plan of
distribution  not  previously  disclosed  in the  Registration  Statement or any
material change to such information in the Registration Statement;

provided,  however,  that  paragraphs  A(1)(i) and  A(1)(ii) do not apply if the
Registration  Statement  is on  Form  S-3  and the  information  required  to be
included in a  post-effective  amendment  by those  paragraphs  is  contained in
periodic  reports  filed by UDS  pursuant to Section 13 or Section  15(d) of the
Securities  Exchange Act of 1934 (the "Exchange  Act") that are  incorporated by
reference in the Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

     (3) To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     B. Undertaking  Regarding  Filings  Incorporating  Subsequent  Exchange Act
Documents by Reference.
     The  Registrants  hereby  undertake  that, for purposes of determining  any
liability  under the Securities Act, each filing of UDS's annual report pursuant
to Section  13(a) or Section 15(d) of the Exchange Act (and,  where  applicable,
each filing of an employee  benefit  plan's  annual  report  pursuant to Section
15(d) of the Exchange Act) that is incorporated by reference in the Registration
Statement  shall be deemed to be a new  Registration  Statement  relating to the
securities  offered  therein,  and the offering of such  securities at that time
shall be deemed to be the initial bona fide offering thereof.

     C.  Undertaking in Respect of Indemnification.

     Insofar as  indemnification  for  liabilities  arising under the Act may be
permitted to directors,  officers,  and  controlling  persons of the Registrants
pursuant to the provisions  described and the documents referenced under Item 15
above, or otherwise,  the  Registrants  have been advised that in the opinion of
the Securities and Exchange  Commission such  indemnification  is against public
policy as expressed in the Act and is,  therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by the registrant of expenses  incurred or paid by a director,  officer,
or controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer, or controlling person
in connection with the securities being registered, the Registrants will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the adjudication of such issue.

     D.  Undertaking regarding Post-Effective Amendments.

     The undersigned Registrants hereby undertake that:

     (1) For purposes of determining  any liability  under the Securities act of
1933, the information  omitted from the form of prospectus filed as part of this
Registration  Statement  in reliance  upon Rule 430A and  contained in a form of
prospectus filed by the Registrants  pursuant to Rule 424(b)(1) or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  Registration
Statement as of the time it was declared effective.

     (2) For the purpose of determining  any liability  under the Securities Act
of 1933, each post-effective  amendment that contains a form of prospectus shall
be deemed to be a new registration  statement relating to the securities offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

     Pursuant to the requirements of the Securities Act of 1933, the undersigned
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Registration
Statement  or amendment  thereto to be signed on its behalf by the  undersigned,
thereunto  duly  authorized,  in the City of San  Antonio  and State of Texas on
