                         CLASS B COMMON STOCK ISSUABLE
                       UPON CONVERSION OF THE DEBENTURES

     We issued the debentures in a private placement in June, 2000 at an issue
price of $425.90 per debenture. This prospectus will be used by selling
securityholders to resell their debentures and the class B common stock issuable
upon conversion of their debentures.

     We will pay interest on the debentures semiannually in arrears on June 23
and December 23 of each year, beginning December 23, 2000, at the rate of .426%
per year on the principal amount at maturity. The rate of cash interest and
accrual of original issue discount represent a yield to maturity of 5% per year.

     Holders may convert the debentures at any time on or before the maturity
date into 5.6024 shares of our class B common stock per debenture. The
conversion rate may be adjusted for various reasons, but will not be adjusted
for accrued original issue discount or accrued cash interest.

     Holders may require us to purchase all or a portion of their debentures at
a price of $543.41 on June 23, 2006, $643.48 on June 23, 2010 and $799.84 on
June 23, 2015, plus accrued and unpaid cash interest to each purchase date. We
may choose to pay the purchase price in cash or class B common stock or a
combination of cash and class B common stock. In addition, each holder may
require us to repurchase all or a portion of such holder's debentures upon a
change in control occurring on or before June 23, 2006. We may redeem all or a
portion of the debentures at any time on or after June 23, 2006.

     Our class B common stock currently trades on the New York Stock Exchange
under the symbol "UHS." The last reported sales price of our class B common
stock on the New York Stock Exchange was $82 7/8 per share on October 30, 2000.

                           Universal Health Services

     Our principal business is owning and operating acute care hospitals,
behavioral health centers, ambulatory surgery centers, radiation oncology
centers and women's centers.  Presently, we operate 60 hospitals, consisting of
23 acute care hospitals, 35 behavioral health centers, and two women's centers.
As part of our Ambulatory Treatment Centers Division, we own, either outright or
in partnership with physicians, and operate or manage 24 surgery and radiation
oncology centers located in 12 states and the District of Columbia.  Our
facilities are located in Arkansas, California, Colorado, Delaware, the District
of Columbia, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana,
Massachusetts, Michigan, Mississippi, Missouri, Nevada, New Jersey, Oklahoma,
Pennsylvania, Puerto Rico, South Carolina, Tennessee, Texas, Utah and
Washington.

     In the second quarter of 2000, our acute care hospitals, ambulatory surgery
centers, radiation oncology centers and women's centers contributed
approximately 85% of our consolidated net revenues and our behavioral health
centers contributed approximately 14% of our consolidated net revenues.

     Services provided by our hospitals include general surgery, internal
medicine, obstetrics, emergency room care, radiology, oncology, diagnostic care,
coronary care, pediatric services and behavioral health services.  Our
facilities benefit from shared centralized services, such as central purchasing,
information services, finance and control systems, facilities planning,
physician recruitment services, administrative personnel management, marketing
and public relations.

                                   Strategy

     Our strategy to enhance our profitability and to continue to provide high-
quality, cost-effective healthcare services includes the following key elements:

 .  Establish and maintain market leadership positions in small and medium-sized
   markets experiencing above-average population growth. Eighty percent of our
   acute care hospitals are the largest or second-largest healthcare providers
   in their respective markets, based upon the number of patients discharged.
   Our facilities are primarily located in markets with populations between
   75,000 and 400,000 that are projected to grow above the national average
   rate. For example, we own eight facilities located in three of the five
   fastest-growing metropolitan areas in the United States.

 .  Provide a differentiated quality of healthcare. In 1999, our hospitals that
   were surveyed by the Joint Commission on Accreditation of Healthcare
   Organizations averaged a score of 95.4, which was above the industry average.
   UHS continually seeks to improve the quality of the service that it delivers
   through its company-wide Service Excellence Program as well as by conducting
   extensive surveys of patients, physicians and employees.

 .  Expand by selectively acquiring, constructing or leasing additional hospital
   facilities. We continually evaluate expansion opportunities, including
   acquisitions, which may provide us with access to new markets and new health
   care delivery capabilities. We describe some of our recent acquisitions and
   construction projects below.

 .  Improve financial performance of existing facilities. We seek to increase the
   operating revenues and profitability of our hospitals by introducing new
   services, improving existing services, recruiting physicians and applying
   financial and operational controls.

 .  Develop and maintain strong relationships with physicians. We support the
   growth of independent physician practices through marketing, partner
   recruiting, practice management, information systems, and creation and
   management of preferred provider networks.

 .  Maintain a low cost structure. We implement programs designed to improve
   financial performance and efficiency while continuing to provide quality
   care, including using professional staff more efficiently, monitoring and
   adjusting staffing levels and equipment usage, improving patient management
   and reporting procedures and implementing more efficient billing and
   collection procedures.


Recent Acquisitions and Construction Projects

     We proactively identify acquisition targets in addition to responding to
requests for proposals from entities that are seeking to sell or lease hospital
facilities.  As a result, we may enter into agreements to acquire hospital
facilities from time to time and at any time, and we are currently actively
involved in negotiations concerning possible acquisitions.  In addition, we are
actively involved in constructing replacement facilities and expanding our
existing facilities.  Our recent acquisitions and construction projects include
the following:

 .  In June 1999, we acquired the assets and operations of Doctors' Hospital of
   Laredo in exchange for the assets and operations of our Victoria Regional
   Medical Center in Victoria, Texas. In connection with this transaction, we
   also purchased additional land in Laredo, Texas on which we are currently
   constructing a 180 licensed bed replacement hospital scheduled to be
   completed in the second quarter of 2001. We estimate that the costs of
   construction and new equipment for the replacement hospital will total
   approximately $45 million.

 .  On July 31, 2000, we completed the purchase of St. Mary's Mercy Hospital, a
   full service, 277 licensed bed hospital located in Enid, Oklahoma. St. Mary's
   Mercy Hospital is the leading hospital in Enid and provides comprehensive
   medical and surgical services including a trauma center and comprehensive
   neuroscience services. For the fiscal year ended June 30, 1999, St. Mary's
   generated approximately $52 million in net revenues and $6.4 million in
   earnings before interest, taxes, depreciation and amortization (EBITDA). We
   estimate that the total purchase price, including expected working capital
   contributions, will be approximately $43 million.

 .  On August 18, 2000, we completed the purchase of 11 behavioral health
   facilities with over 1,400 licensed beds from Charter Behavioral Health
   Systems, LLC and acquired the real estate assets associated with these
   businesses plus one additional behavioral health property from Crescent Real
   Estate Funding VII LP. In 1999, the acquired facilities produced
   approximately $150 million in net revenues and $27 million in EBITDA. We
   estimate that the total purchase price, including expected working capital
   contributions, will be approximately $105 million.

 .  In September, 2000, we purchased Fort Duncan Medical Center, a 77 licensed
   bed acute care facility located in Eagle Pass, Texas. Subject to the terms of
   the purchase agreement, we are committed to building a replacement hospital
   with a least 100 licensed beds within six years. For the fiscal year ended
   June 30, 1999, Fort Duncan Medical Center generated approximately $29 million
   in net revenues and $3.4 million in EBITDA. The purchase price of the
   facility was $10 million and we estimate that the cost of construction and
   new equipment for the replacement hospital will total approximately $25
   million.

 .  We are building a 371 licensed bed replacement hospital for The George
   Washington University Hospital in Washington, D.C. We expect to complete the
   construction in the second quarter of 2002 and estimate that our share of the
   costs of construction and new equipment will total approximately $80 million
   to $83 million, $40 million of which we funded at acquisition in 1997 with a
   restricted cash investment account.

                                       6

 .  We are expanding our Desert Springs Hospital in Las Vegas, Nevada to increase
   its licensed capacity from 233 to 353 beds. We expect to complete the
   expansion in the first quarter of 2001 and estimate that the costs of
   construction and new equipment will total approximately $15 million.

 .  We expect to commence a renovation and expansion of Auburn Regional Medical
   Center in Auburn, Washington in December of 2000. The renovated and expanded
   facility will include a new operating room, emergency room, obstetrics
   department and approximately 40 additional licensed beds. We expect to
   complete this project in the fourth quarter of 2001, and estimate that the
   costs of construction and new equipment will total approximately $15 million
   to $18 million.

                                   2000.


Conversion rights................  Holders may convert the debentures at any
                                   time. For each debenture converted, we will
                                   deliver 5.6024 shares of our class B common
                                   stock or, at our option, cash in an amount
                                   equal to the value of those shares. The
                                   conversion rate may be adjusted for various
                                   reasons, but will not be adjusted for accrued
                                   original issue discount, cash interest or
                                   interest payable upon the occurrence of a tax
                                   event. Upon conversion, the holder will not
                                   receive any cash payment representing accrued
                                   original issue discount or any accrued
                                   interest; such accrued original issue
                                   discount and accrued cash interest will be
                                   deemed paid by the shares of class B common
                                   stock or cash received by the holder on
                                   conversion.

Ranking..........................  The debentures are unsecured and
                                   unsubordinated obligations and rank equally
                                   in right of payment with all of our existing
                                   and future unsecured and unsubordinated
                                   indebtedness.

Original issue discount..........  We offered each debenture at an original
                                   issue discount for U.S. federal income tax
                                   purposes equal to the principal amount at
                                   maturity of the debenture, $1,000, less the
                                   issue price, $425.90. You should be aware
                                   that as original issue discount accrues, it
                                   must be included in your gross income for
                                   U.S. federal income tax purposes.

Sinking fund.....................  None.

Optional redemption.............   We may redeem all or a portion of the
                                   debentures for cash at any time, on or after

                                   the issue price of the debentures plus

Change in control................  Upon a change in control of UHS occurring on
                                   or before June 23, 2006 each holder may
                                   require us to repurchase all or a portion of
                                   such holder's debentures at a price equal to

                                 RISK FACTORS

     This prospectus contains forward-looking statements that involve a number
of risks and uncertainties inherent in the purchase of the debentures or shares
of our class B common stock.  You should be aware that such statements are
projections or estimates as to future events, which may or may not occur.

     In addition to the other information in this prospectus, you should
carefully consider the following risk factors before deciding whether an
investment in the debentures is suitable for you.  If any of the adverse events
contemplated by these risk factors actually occur, our business, financial
condition and results of operations could be materially adversely affected.  The
risks and uncertainties described below are not the only ones facing our
company, and additional risks and uncertainties may also impair our business
operations.

If government programs or managed care companies reduce the payments we receive
as reimbursement for our services, our revenues may decline.

     We derive a substantial portion of our net revenues from third-party
payors, including the Medicare and Medicaid programs.  Changes in government
reimbursement programs have resulted in limitations on the growth rates of the
reimbursement programs and, in some cases, in reduced levels of reimbursement
for healthcare services, and additional changes are anticipated.  The Balanced
Budget Act of 1997, which established a plan to balance the federal budget by
fiscal year 2002, includes significant reductions in spending levels for the
Medicare and Medicaid programs, including:

 .  payment reductions for inpatient and outpatient hospital services;

 .  establishment of a prospective payment system for outpatient hospital
   services that commenced on August 1, 2000; and

 .  repeal of the federal payment standard often referred to as the "Boren
   Amendment" for hospitals and nursing facilities, which could result in lower
   Medicaid reimbursement rates.

     The Balanced Budget Refinement Act of 1999 is expected to reduce the
adverse effects of the Balanced Budget Act of 1997 through a corridor
reimbursement approach, where a percentage of losses under the Medicare
outpatient prospective payment system will be reimbursed through December 31,
2003.  Substantially all of our hospitals qualify for relief under this
provision.  Inpatient reimbursement for behavioral health facilities converts to
a prospective payment system effective January 1, 2004.

     In addition to changes in government reimbursement programs, private
payors, including managed care payors, increasingly are demanding discounted fee
structures or the assumption by healthcare providers of all or a portion of the
financial risk through prepaid capitation arrangements.  Inpatient utilization,
average lengths of stay and occupancy rates continue to be negatively affected
by payor-required pre-admission authorization and utilization review and by
payor pressure to maximize outpatient and alternative healthcare delivery
services for less acutely ill patients.

     We expect efforts to impose reduced allowances, greater discounts and more
stringent cost controls by government and other payors to continue.  We believe
that additional reductions in the payments we receive for our services could
reduce our overall revenues.


If we fail to comply with extensive laws and government regulations, we could
suffer penalties or be required to make significant changes to our operations.

     The healthcare industry is required to comply with many laws and
regulations at the federal, state and local government levels.  These laws and
regulations require that hospitals meet various requirements, including those
relating to the adequacy of medical care, equipment, personnel, operating
policies and procedures, maintenance of adequate records, compliance with
building codes, and environmental protection.  If we fail to comply with

                                       10
<PAGE>

applicable laws and regulations, we could suffer civil and criminal penalties,
including the loss of our licenses to operate and our ability to participate in
Medicare, Medicaid, and other federal and state healthcare programs.

     In addition, there are heightened coordinated civil and criminal
enforcement efforts by both federal and state government agencies relating to
the healthcare industry, including the hospital segment.  The ongoing
investigations relate to various referral, cost reporting, and billing
practices, laboratory and home healthcare services, and physician ownership and
joint ventures involving hospitals.

     In the future, different interpretations or enforcement of these laws and
regulations could subject our current practices to allegations of impropriety or
illegality or could require us to make changes in our facilities, equipment,
personnel, services, capital expenditure programs, and operating expenses.


We are subject to uncertainties regarding healthcare reform.

     In recent years, an increasing number of legislative initiatives have been
introduced or proposed in Congress and in state legislatures that would effect
major changes in the healthcare system, either nationally or at the state level.
Among the proposals that have been introduced are price controls on hospitals,
insurance market reforms to increase the availability of group health insurance
to small businesses, requirements that all businesses offer health insurance
coverage to their employees and the creation of a government health insurance
plan or plans that would cover all citizens and increase payments by
beneficiaries.  We cannot predict whether any of the above proposals or any
other proposals will be adopted, and if adopted, no assurance can be given that
the implementation of such reforms will not have a material adverse effect on
our business.

     Since 1995, the State of Texas has rolled out Medicaid managed care pilot
programs in several geographic areas of the state.  Effective fall 1999,
however, the Texas legislature imposed a moratorium on the implementation of
additional pilot programs pending receipt of a study of the effectiveness of
Medicaid managed care.  We are unable to predict the effect on our business of
changes to any current or any future pilot programs.

     Upon meeting certain conditions, and serving a disproportionately high
share of Texas' and South Carolina's low income patients, four of our facilities
located in Texas and one facility located in South Carolina became eligible and
received additional reimbursement from each state's disproportionate share
hospital fund.  Included in our financial results were aggregate revenues of
$33.4 million in 1997, $36.5 million in 1998, and $37.0 million in 1999,
received pursuant to the terms of these programs. Texas and South Carolina
recently renewed their respective programs, but the extent of our eligibility
for reimbursement under each program will likely be reduced.  The
discontinuation of these programs, or further reduction of reimbursement, could
have a material adverse effect on our future results of operations.

Our growth strategy includes acquisitions, and we may not be able to acquire
hospitals that meet our target criteria.  We may also face regulatory hurdles in
acquiring hospitals from not-for-profit entities.

     One element of our growth strategy is expansion through the acquisition of
hospitals in markets that are attractive to us.  We face competition for
acquisitions primarily from other for-profit health care companies as well as
not-for-profit entities.  Some of our competitors have greater financial and
other resources than we do.  As a result, we may not be able to effectively
accomplish this element of our growth strategy.

     Hospital acquisitions generally require a longer period to complete than
acquisitions in many other businesses and are subject to additional regulatory
uncertainty.  In recent years, the legislatures and attorneys general of some
states have shown a heightened level of interest in transactions involving the
sale of hospitals by not-for-profit entities.  Although the level of interest
varies from state to state, the trend is to provide for increased governmental
review, and in some cases approval, of transactions in which not-for-profit
entities sell a healthcare facility.  Although we have not been adversely
affected as a result of these trends, such increased scrutiny may increase the
difficulty or prevent the completion of transactions with not-for-profit
organizations in certain states in the future.

Our revenue and EBITDA are heavily concentrated in our facilities in the South
Texas and Las Vegas, Nevada markets.

     McAllen Medical Center, located in McAllen, Texas, and Edinburg Regional
Medical Center, located in Edinburg, Texas, operate in the same market.  On a
combined basis, these two facilities contributed 16% in 1997 and 13% in both
1998 and 1999 of our consolidated net revenues and 25% in 1997, 23% in 1998 and
25% in 1999 of our consolidated earnings before interest, income taxes,
depreciation, amortization, and nonrecurring charges (after deducting an
allocation of corporate overhead) (EBITDA).

     Valley Hospital Medical Center, Summerlin Hospital Medical Center and
Desert Springs Hospital all operate within the Las Vegas, Nevada market.  Valley
Hospital Medical Center and Summerlin Hospital Medical Center (which opened
during the fourth quarter of 1997) contributed 13% of our 1997 consolidated net
revenues and 18% of our 1997 consolidated EBITDA.  On a combined basis, Valley
Hospital Medical Center, Summerlin Hospital Medical Center and Desert Springs
Hospital contributed 18% of our consolidated net revenues in both 1998 and 1999
and 15% in 1998 and 10% in 1999 of our consolidated EBITDA.

     Any adverse change in the economic, competitive or regulatory conditions in
the South Texas or Las Vegas, Nevada markets in which these hospitals operate
could significantly reduce our revenues and EBITDA.

Other hospitals provide comparable services, which may raise the level of
competition faced by our hospitals.

     In all geographical areas in which we operate, there are other hospitals
which provide services comparable to those offered by our hospitals, some of
which are owned by governmental agencies and supported by tax revenues, and
others of which are owned by not-for-profit corporations and may be supported to
a large extent by endowments and charitable contributions.  Such support is not
available to our hospitals.  Certain of our competitors have greater financial
resources than we do, are better equipped than we are and offer a broader range
of services than we do.  Outpatient treatment and diagnostic facilities,
outpatient surgical centers and freestanding ambulatory surgical centers also
affect the healthcare marketplace.  In recent years, competition among
healthcare providers for patients has intensified as hospital occupancy rates in
the United States have declined due to, among other things, regulatory and
technological changes, increasing use of managed care payment systems, cost
containment pressures, a shift toward outpatient treatment and an increasing
supply of physicians.  There can be no assurance that our hospitals will
continue to be able to compete effectively in attracting patients under these
changing circumstances.

Our success depends upon our ability to recruit and retain physicians at our
hospitals.

     With a few exceptions, physicians are not employees of our hospitals and
members of the medical staffs of our hospitals also serve on medical staffs of
hospitals not owned by us and may terminate their affiliation with our hospitals
at any time.  Our future success will depend, in part, on the ability of our
hospitals to continue to attract and retain quality physicians and to organize
and structure integrated healthcare delivery systems with other healthcare
providers and physician practice groups.  There can be no assurance that our
hospitals will continue to be able, on terms favorable to us, to attract
physicians to their staffs, or to organize and structure integrated healthcare
delivery systems, for which other healthcare companies with greater financial
resources or a wider range of services may be competing.

Our controlling stockholder can determine the outcome of virtually all matters
requiring stockholder approval.

     Alan B. Miller, UHS's Chairman of the Board, President and Chief Executive
Officer, controls approximately 82.4% of the general voting power of UHS.  Mr.
Miller also controls an aggregate of 94.1% of the class A common stock, 9.7% of
the class B common stock and 93.5% of class C common stock.  As such, Mr. Miller
can elect 80% of UHS's Board of Directors and accomplish a merger, sale,
transfer of assets or other significant transaction without the approval of our
other stockholders.  The existence of a controlling stockholder may limit your
ability, as a holder of class B common stock upon conversion of the debentures,
to influence the outcome of matters requiring stockholder approval.

                                      12

Our liability insurance coverage is limited.

     Effective January 1, 1998, our subsidiaries are covered under commercial
insurance policies which provide for a self-insured retention limit for
professional and general liability claims for most of our subsidiaries up to $1
million per occurrence, with an average annual aggregate for covered
subsidiaries of $6 million through 2001.  These subsidiaries maintain excess
coverage up to $100 million with major insurance carriers.  Our remaining
facilities are fully insured under commercial policies with excess coverage up
to $100 million maintained with major insurance carriers.  Since 1993, certain
of our subsidiaries, including one of our larger acute care facilities, have
purchased general and professional liability occurrence policies with commercial
insurers.  These policies include coverage up to $25 million per occurrence for
general and professional liability risks.  If our liabilities exceed our
insurance coverage, our financial condition and results of operations could be
adversely affected.

We may need to obtain additional financing to fund acquisitions and capital
expenditures, and we cannot be sure that additional financing will be available
when needed.

     We require substantial capital resources to fund our acquisitions.  The
operations of our existing hospitals require ongoing capital expenditures for
renovation, expansion and the addition of medical equipment and technology
utilized in the hospitals.  For example, we expect to construct a replacement
hospital scheduled to be completed in the second quarter of 2001 for the
Doctors' Hospital of Laredo, are building a replacement hospital for The George
Washington University Hospital expected to be completed in the second quarter of
2002, are expanding Desert Springs Hospital and expect to complete this
expansion in the first quarter of 2001, and expect to commence a renovation and
expansion of our Auburn Regional Medical Center in December of 2000 and to
complete the project in the fourth quarter of 2001. In addition, we recently
acquired St. Mary's Hospital in Enid, Oklahoma, 11 behavioral health facilities
from Charter Behavioral Health Systems, LLC and the real estate assets
associated with these businesses plus one additional behavioral health property
from Crescent Real Estate Funding VII LP, and Fort Duncan Medical Center in
Eagle Pass, Texas for which we are committed, subject to the terms of the
purchase agreement, to building a replacement hospital within six years.

     We may need to incur additional indebtedness and may issue, from time to
time, debt or equity securities to fund acquisitions or capital expenditures.
We cannot assure you that sufficient financing will be available to us on
satisfactory terms or that our level of indebtedness may not restrict our
ability to borrow additional funds.

We may not be able to repurchase or redeem debentures.

     On June 23, 2006, June 23, 2010 and June 23, 2015, the holders may require
us to purchase their debentures.  If the holders require us to purchase their
debentures on one of these dates, we could have insufficient funds to complete
the purchase.  In addition, upon a change in control of UHS occurring on or
before June 23, 2006, each holder may require us to repurchase all or a portion
of such holder's debentures.  If a change in control occurs, we cannot assure
you that we will have sufficient funds to pay the change in control purchase
price if you exercise your right to require us to purchase your debentures.

Fluctuations in the market price of our class B common stock may affect the
price of the debentures.

     Because the debentures are convertible into shares of our class B common
stock, fluctuations in the market price of class B common stock may affect the
price of the debentures.  The market prices for our class B common stock and for
securities of other companies engaged primarily in healthcare services are
subject to wide fluctuations.  For example, the sale prices of our class B
common stock, as reported by the New York Stock Exchange, fluctuated between
$36 1/8 per share and $89 1/2 per share during the first nine months of 2000.
The market price of our class B common stock may continue to fluctuate due to a
variety of factors, including:

 .  future issuances of class B common stock;

 .  material public announcements;

 .  regulatory approvals or regulatory issues;

                                       13
<PAGE>

 .  political developments or proposed legislation in the healthcare industry;

 .  period to period fluctuations in our financial results; and

 .  market trends relating to our industry.

Absence of existing active public market.

     Upon their original issuance, the debentures became eligible for trading on
The PORTAL Market.  The debentures sold pursuant to this prospectus, however,
will no longer be eligible for trading on The PORTAL Market and we do not intend
to apply for listing of the debentures on any securities exchange or quotation
system.  We can not assure you that an active trading market for the debentures
will develop or as to the liquidity or sustainability of any such market, the
ability of the holders to sell their debentures or the price at which holders of
the debentures will be able to sell their debentures.  Future trading prices of
the debentures will depend on many factors, including, among other things,
prevailing interest rates, our operating results, the price of our class B
common stock and the market for similar securities.

                                USE OF PROCEEDS

     The selling securityholders will receive all of the proceeds from the sale
of the debentures and class B common stock under this prospectus.  We will not
receive any of the proceeds from their sales of debentures or class B common
stock.

                      RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our consolidated ratios of earnings to fixed
charges for each of the years ended December 31, 1995, 1996, 1997, 1998 and 1999
and for each of the six months ended June 30, 1999 and 2000:

     The ratio of earnings to fixed charges is computed by dividing fixed
charges into earnings from continuing operations before income tax and
extraordinary items plus fixed charges.  Fixed charges include interest expense,
interest element of lease rental expense, and amortization of debt issuance
costs.

                                DIVIDEND POLICY

     We have historically not paid cash dividends on our capital stock and we do
not anticipate paying cash dividends on our class B common stock in the
foreseeable future.

                           DESCRIPTION OF DEBENTURES

     We issued the debentures under an indenture dated as of June 23, 2000
between UHS and Bank One Trust Company, N.A., as trustee.  The form of indenture
(including the form of debenture which is part of the indenture) was previously
filed with the SEC and has been incorporated by reference as an exhibit to this
registration statement.  The following summaries of certain provisions of the
debentures and the indenture do not purport to be complete and are subject to,
and are qualified in their entirety by reference to, all of the provisions of
the debentures and the indenture.  Wherever particular provisions of the
indenture (or of the form of debenture which is a part of the indenture) are
referred to, such provisions are incorporated by reference in this prospectus.
As used in this description, references to "we," "us," "our" or "UHS" do not
include any current or future subsidiary of UHS.

General

     The debentures are unsecured obligations of UHS limited to $586,992,000
aggregate principal amount at maturity.  The debentures will mature on June 23,
2020.  The principal amount at maturity of each debenture is $1,000 and will be
payable at the office of the paying agent, which initially is the trustee, or an
office or agency maintained by us for such purpose, in the Borough of Manhattan,
The City of New York.

     The debentures were originally offered at a substantial discount from their
principal amount at maturity.  See "Federal Income Tax Considerations--Original
Issue Discount."  The debentures will accrue original issue discount while they
remain outstanding.  Original issue discount is the difference between the issue
price and the principal amount at maturity of a debenture.  The calculation of
the accrual of original issue discount will be on a semiannual bond equivalent
basis using a 360-day year composed of twelve 30-day months.  Original issue
discount began to accrue on June 23, 2000, the issue date of the debentures.
The debentures also bear interest at the rate of 5.00% per year on the principal
amount at maturity from the issue date, or from the most recent date to which
interest has been paid or provided for, until the debentures are paid in full or
funds are made available for payment in full in accordance with the indenture.
Cash interest will be payable at maturity (or earlier date of purchase,
redemption or, in certain circumstances, conversion) and semiannually in arrears
on June 23 and December 23 of each year, commencing on December 23, 2000, to
holders of record at the close of business on the June 8 or December 8 (whether
or not a business day) immediately preceding such interest payment date.  Each
payment of cash interest on the debentures will include interest accrued through
the day before the applicable interest payment date or the date of maturity (or
earlier purchase, redemption or, in certain circumstances, conversion), as the
case may be.  Any payment required to be made on any day that is not a business
day will be made on the next succeeding business day.  In the event of the
maturity, conversion, purchase by UHS at the option of a holder or redemption of
a debenture, original issue discount and cash interest will cease to accrue on
such debenture under the terms of and subject to the conditions in the
indenture.  We may not reissue a debenture that has matured or been converted,
purchased by UHS at the option of a holder, redeemed or otherwise cancelled
(except for registration of transfer, exchange or replacement thereof).

     Debentures may be presented for conversion at the office of the conversion
agent and for exchange or registration of transfer at the office of the
registrar.  Each such agent is initially the trustee.  We will not charge a
service charge for any registration of transfer or exchange of debentures.

Book-Entry Form

     The debentures were issued in the form of global securities held in book-
entry form.  DTC or its nominee is the sole registered holder of the debentures
for all purposes under the indenture.  Owners of beneficial interests in the
debentures represented by the global security will hold such interests pursuant
to the procedures and practices of DTC.  As a result, owners of beneficial
interests must exercise any rights in respect of their interests, including any
right to convert or require repurchase of their interests, in accordance with
the procedures and practices of DTC.  Beneficial owners will not be holders and
will not be entitled to any rights under the global securities or the indenture
provided to the holders of the debentures.  UHS and the trustee, and any of
their respective agents, may treat DTC as the sole holder and registered owner
of the global securities.

     Certificated debentures may be issued in exchange for beneficial interests
in debentures represented by a global debenture only in the limited
circumstances set forth in the indenture.

                                       15
<PAGE>

Absence of Existing Active Public Market

     Upon their original issuance, the debentures became eligible for trading on
The PORTAL Market.  The debentures sold pursuant to this prospectus, however,
will no longer be eligible for trading on The PORTAL Market and we do not intend
to apply for listing of the debentures on any securities exchange or quotation
system.  We can not assure you that an active trading market for the debentures
will develop or as to the liquidity or sustainability of any such market, the
ability of the holders to sell their debentures or the price at which holders of
the debentures will be able to sell their debentures.  Future trading prices of
the debentures will depend on many factors, including, among other things,
prevailing interest rates, our operating results, the price of our class B
common stock and the market for similar securities.

Conversion Rights

     A holder may convert a debenture, in integral multiples of $1,000 principal
amount at maturity, into shares of class B common stock at any time before the
close of business on June 23, 2020.  However, a holder may convert a debenture
only until the close of business on the redemption date if we call the debenture
for redemption.  A debenture for which a holder has delivered a purchase notice
or a change in control purchase notice requiring us to purchase that debenture
may be converted only if such notice is withdrawn in the manner and by the time
provided in the indenture.

     The initial conversion rate for the debentures is 5.6024 shares of class B
common stock per $1,000 principal amount at maturity, subject to adjustment upon
the occurrence of various events described below.  We will pay cash in lieu of
any fractional share in an amount equal to the value of such fractional share
based on the Sale Price (as defined below) on the trading day immediately
preceding the conversion date.

     To convert a debenture, a holder must:

 .  complete and manually sign the conversion notice on the back of the debenture
   (or complete and manually sign a facsimile of such notice) and deliver such
   notice to the conversion agent (initially the trustee) at the office
   maintained by the conversion agent for such purpose;

 .  surrender the debenture to the conversion agent;

 .  if required, furnish appropriate endorsements and transfer documents; and

 .  if required, pay all transfer or similar taxes.

     Pursuant to the indenture, the date on which all of the foregoing
requirements have been satisfied is the conversion date.

     Upon conversion of a debenture, a holder will not receive any cash payment
representing accrued original issue discount or, except as described below,
accrued cash interest.  Our delivery to the holder of the fixed number of shares
of class B common stock into which the debenture is convertible, together with
any cash payment in lieu of any fractional shares, will be deemed to satisfy our
obligation to pay:

 .  the principal amount at maturity of the debenture; and

 .  the accrued original issue discount and accrued cash interest attributable to
   the period from the issue date to the conversion date.

     As a result, accrued original issue discount and accrued cash interest will
be deemed to be paid in full rather than canceled, extinguished or forfeited.
Notwithstanding the foregoing, accrued but unpaid cash interest will be payable
upon any conversion of debentures at the option of the holder made concurrently
with or after acceleration of the debentures following an event of default
described under "--Events of Default; Notice and

                                       16
<PAGE>

Waiver" below. Debentures surrendered for conversion during the period from the
close of business on any regular record date next preceding any interest payment
date to the opening of business of such interest payment date (except debentures
to be redeemed on a date within such period or on the next interest payment
date) must be accompanied by payment of an amount equal to the interest thereon
that the registered holder is to receive. Except where debentures surrendered
for conversion must be accompanied by payment as described above, no interest on
converted debentures will be payable by us on any interest payment date
subsequent to the date of conversion.

     The conversion rate will not be adjusted at any time during the term of the
debentures for accrued original issue discount or accrued cash interest. A
certificate for the number of full shares of class B common stock into which any
debenture is converted, together with cash in lieu of any fractional shares,
will be delivered through the conversion agent as soon as practicable, but in
any event no later than the seventh business day following the conversion date.
For a discussion of the U.S. federal income tax treatment of a holder receiving
class B common stock upon conversion, see "Federal Income Tax Considerations--
Disposition or Conversion of Debentures."

     If we exercise our option to have interest in lieu of original issue
discount accrue on a debenture following a tax event, the holder will be
entitled on conversion to receive the same number of shares of class B common
stock such holder would have received if we had not exercised our option.  See
"--Optional Conversion to Semiannual Coupon Debenture upon Tax Event."

     The conversion rate is subject to adjustment in certain events, including:

 .  the issuance of shares of class B common stock or other capital stock as a
   dividend or a distribution with respect to class B common stock;

 .  subdivisions, combinations and reclassification of class B common stock;

 .  the issuance to all holders of class B common stock of rights or warrants
   entitling them for a period not exceeding 45 days to subscribe for shares of
   class B common stock at less than the then Market Price (as defined below) of
   the class B common stock;

 .  the distribution to all holders of class B common stock of evidences of
   indebtedness of UHS, securities or capital stock, cash or assets (including
   securities, but excluding those rights, warrants, dividends and distributions
   referred to above and dividends and distributions paid exclusively in cash);

 .  the payment of dividends and other distributions on class B common stock paid
   exclusively in cash, excluding cash dividends if the annualized per share
   amount thereof does not exceed 10% of the Market Price of class B common
   stock on the trading day immediately preceding the date of declaration of
   such dividend or other distribution; and

 .  payment to holders of class B common stock in respect of a tender or exchange
   offer (other than an odd-lot offer) by UHS or any of our subsidiaries for
   class B common stock at a price in excess of 110% of the then Market Price of
   class B common stock on the trading day next succeeding the last date tenders
   or exchanges may be made pursuant to such tender or exchange offer.

     However, no adjustment need be made if holders may participate in the
transactions otherwise giving rise to an adjustment on a basis and with notice
that our board of directors determines to be fair and appropriate, or in certain
other cases.  In cases where the fair market value of the portion of assets,
debt securities or rights, warrants or options to purchase securities of UHS
applicable to one share of class B common stock distributed to stockholders
equals or exceeds the average quoted price per share of class B common stock, or
such average quoted price exceeds such fair market value of such portion of
assets, debt securities or rights, warrants or options so distributed by less
than $1.00, rather than being entitled to an adjustment in the conversion rate,
the holder of a debenture will be entitled to receive upon conversion thereof,
in addition to the shares of class B common stock into which such debenture is
convertible, the kind and amounts of assets, debt securities or rights, options
or warrants comprising the distribution that such holder would have received if
such holder had converted such debenture

                                       17
<PAGE>

immediately prior to the record date for determining the stockholders entitled
to receive the distribution. The indenture permits us to increase the conversion
rate from time to time.

     In the event that we are a party to any transaction, pursuant to which the
class B common stock is converted into the right to receive other securities,
cash or other property, including, without limitation, and with certain
exceptions:

 .  recapitalization or reclassification of the class B common stock,

 .  any consolidation of UHS with, or merger of UHS into, any other person, or
   any merger of another person into UHS,

 .  any sale, transfer or lease of all or substantially all of the assets of UHS,
   or

 .  any compulsory share exchange,

then the holders of debentures then outstanding shall have the right to convert
the debentures into the kind and amount of securities, cash or other property
receivable upon the consummation of such transaction by a holder of the number
of shares of class B common stock issuable upon conversion of such debentures
immediately prior to such transaction.

     In the event that we are a party to such a transaction as described above,
each debenture would become convertible into the securities, cash or property
receivable by a holder of the number of shares of the class B common stock into
which such debenture was convertible immediately prior to such transaction.
This change could substantially lessen or eliminate the value of the conversion
privilege associated with the debentures in the future.  For example, if we were
acquired in a cash merger, each debenture would become convertible solely into
cash and would not longer be convertible into securities whose value would vary
depending on our future prospects and other factors.

     In the event of a taxable distribution to holders of class B common stock
which results in an adjustment of the conversion rate (or in which holders
otherwise participate) or in the event the conversion rate is increased at our
discretion, the holders of the debentures may, in certain circumstances, be
deemed to have received a distribution subject to United States federal income
tax as a dividend.  See "Federal Income Tax Considerations--Adjustment of
Conversion Price."

Redemption of Debentures at the Option of UHS

     No sinking fund is provided for the debentures.  Prior to June 23, 2006,
the debentures will not be redeemable at our option.  On and after that date, we
may redeem the debentures for cash as a whole at any time, or from time to time
in part, at the redemption prices set forth below plus accrued cash interest to
the redemption date.  Any such redemption must be in integral multiples of
$1,000 principal amount at maturity.  We will give not less than 30 days nor
more than 60 days notice of redemption by mail to holders of debentures.

     The table below shows redemption prices of a debenture per $1,000 principal
amount at maturity on June 23, 2000, at each June 23 thereafter prior to
maturity, and at maturity on June 23, 2020.  These prices reflect the accrued
original issue discount calculated to each such date.  The redemption price of a
debenture redeemed between such dates would include an additional amount
reflecting the additional original issue discount accrued since the next
preceding date in the table to the redemption date.

     If converted to semiannual coupon debentures following the occurrence of a
tax event, the debentures will be redeemable at the restated principal amount
plus accrued and unpaid interest from the date of such conversion to the
redemption date.  However, in no event may the debentures be redeemed prior to
June 23, 2006.  See "--Optional Conversion to Semiannual Coupon Debenture upon
Tax Event."

     If less than all of the outstanding debentures are to be redeemed, the
trustee shall select the debentures to be redeemed in principal amounts at
maturity of $1,000 or integral multiples of $1,000 by lot, pro rata or by
another method the trustee considers fair and appropriate.  If a portion of a
holder's debentures is selected for partial redemption and such holder converts
a portion of such debentures prior to such redemption, such converted portion
will be deemed, solely for purposes of determining the aggregate principal
amount at maturity of the debentures to be redeemed by us, to be of the portion
selected for redemption.

Purchase of Debentures by UHS at the Option of the Holder

     On June 23, 2006, June 23, 2010 and June 23, 2015, we will, at the option
of the holder, be required to purchase, at the purchase prices set forth below
plus accrued cash interest to the purchase date, any outstanding debenture for
which a written purchase notice has been properly delivered by the holder and
not withdrawn, subject to certain additional conditions.  Holders may submit
their debentures for purchase to the paying agent at any time from the opening
of business on the date that is 20 business days before such purchase date until
the close of business on such purchase date.

     The purchase price of a debenture will be:

 .  $543.41 per debenture on June 23, 2006;

 .  $643.48 per debenture on June 23, 2010; and

 .  $799.84 per debenture on June 23, 2015.

     These purchase prices equal the issue price plus accrued original issue
discount to the applicable purchase date.

     We may, at our option, elect to pay the purchase price in cash or shares of
class B common stock, or any combination thereof.  For a summary of the U.S.
federal income tax treatment of a holder receiving cash, class B common stock or
any combination thereof, see "Federal Income Tax Considerations--Disposition or
Conversion."

                                       19
<PAGE>

     If prior to a purchase date the debentures have been converted to
semiannual coupon debentures following the occurrence of a tax event, the
purchase price will be equal to the restated principal amount plus accrued and
unpaid cash interest from the date of the conversion to, but excluding, the
purchase date. See "--Optional Conversion to Semiannual Coupon Debenture upon
Tax Event."

     We will give notice on a date not less than 20 business days prior to each
purchase date to all holders at their addresses shown in the register of the
registrar, and to beneficial owners as required by applicable law, stating among
other things:

 .  whether we will pay the purchase price of the debentures in cash or class B
   common stock or any combination thereof, specifying the percentages of each;

 .  if we elect to pay in shares of class B common stock, in whole or in part,
   the method of calculating the Market Price (as defined below) of the class B
   common stock; and

 .  the procedures that holders must follow to require us to purchase their
   debentures.

     The purchase notice given by any holder requiring us to purchase debentures
will state:

 .  the certificate numbers of the debentures to be delivered by such holder for
   purchase;

 .  the portion of the principal amount at maturity of debentures to be
   purchased, which portion must be $1,000 or an integral multiple thereof;

 .  that the debentures are to be purchased by us pursuant to the applicable
   provisions of the indenture and the debentures; and

 .  if we elect, pursuant to the notice we are required to give, to pay a
   specified percentage of the purchase price in shares of class B common stock
   but such specified percentage is ultimately to be paid to the holder in cash
   because any of the conditions to payment of such specified percentage of the
   purchase price in shares of class B common stock is not satisfied prior to
   the close of business on the purchase date, as described below, whether the
   holder elects (1) to withdraw the purchase notice as to some or all of the
   debentures to which it relates (stating the principal amount at maturity and
   certificate numbers of the debentures as to which such withdrawal relates) or
   (2) to receive cash in respect to the purchase price of all debentures
   subject to such purchase notice.

     If the holder fails to indicate its choice with respect to the election
described in the final bullet point above, the holder will be deemed to have
elected to receive cash for the specific percentage of the purchase price that
was to have been payable in shares of class B common stock.  See "Federal Income
Tax Considerations--Disposition or Conversion."

     Any purchase notice may be withdrawn by the holder by a written notice of
withdrawal delivered to the paying agent prior to the close of business on the
purchase date.  The notice of withdrawal must state the principal amount at
maturity and the certificate numbers of the debentures as to which the
withdrawal notice relates and any principal amount at maturity which remains
subject to the purchase notice.

     If we elect to pay the purchase price, in whole or in part, in shares of
class B common stock, the number of shares of class B common stock to be
delivered by us shall be equal to the portion of the purchase price to be paid
in class B common stock divided by the Market Price of a share of class B common
stock.  Instead of any fractional shares otherwise deliverable as part of the
purchase price, we will pay cash based on the Market Price for such fractional
shares of class B common stock.  See "Federal Income Tax Considerations--
Disposition or Conversion."

     The "Market Price" means the average of the Sale Prices of the class B
common stock for the five trading day period ending on (if the third business
day prior to the applicable purchase date is a trading day, or if not, then on
the last trading day prior to) the third business day prior to the applicable
purchase date, appropriately adjusted to

                                       20
<PAGE>

take into account the occurrence, during the period commencing on the first of
such trading days during such five trading day period and ending on such
purchase date (or other date in question, for purpose of adjusting the
conversion rate), of certain events that would result in an adjustment of the
conversion rate.

     The "Sale Price" of the class B common stock on any date means the closing
per share sale price (or, if no closing sale price is reported, the average of
the bid and ask prices or, if more than one in either case, the average of the
average bid and average ask prices) on such date as reported in the composite
transactions for the principal United States securities exchange on which the
class B common stock is traded or, if the class B common stock is not listed on
a United States national or regional securities exchange, as reported by the
Nasdaq Stock Market.

     A "trading day" means each day on which the securities exchange or
quotation system which is used to determine the Sale Price is open for trading
or quotation. Because the Market Price of the class B common stock is determined
prior to the applicable purchase date, holders of debentures bear the market
risk with respect to the value of the class B common stock to be received from
the date such Market Price is determined to such purchase date. We may pay the
purchase price, or any portion of the purchase price, in class B common stock
only if the information necessary to calculate the Market Price is reported in
The Wall Street Journal or another daily newspaper of national circulation.

     Upon determination of the actual number of shares of class B common stock
issuable in accordance with the foregoing provisions, we will publish such
information in The Wall Street Journal or another daily newspaper of national
circulation.

     Our right to purchase debentures, in whole or in part, with shares of class
B common stock is subject to our satisfying various conditions, including:

 .  the registration of the class B common stock under the Securities Act and the
   Exchange Act, if required; and

 .  any necessary qualification or registration under applicable state securities
   law or the availability of an exemption from such qualification and
   registration.

     If such conditions are not satisfied with respect to a holder prior to the
close of business on the purchase date, we will pay the purchase price of the
debentures in cash.  We may not change the form of consideration (or components
or percentages of components thereof) to be paid for debentures once we have
given the notice we are required to give to holders of debentures, except as
described in the preceding sentence.

     In connection with any purchase offer, we will:

 .  comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender
   offer rules under the Exchange Act which may then be applicable; and

 .  file Schedule TO or any other required schedule under the Exchange Act.

     Payment of the purchase price for a debenture for which a purchase notice
has been delivered and not validly withdrawn is conditioned upon delivery of the
debenture, together with necessary endorsements, to the paying agent, at any
time after delivery of such purchase notice.  Payment of the purchase price for
the debenture will be made promptly following the later of the purchase date and
the time of delivery of the debenture.

     If the paying agent holds money or securities sufficient to pay the
purchase price of the debenture on the business day following the purchase date
in accordance with the terms of the indenture, then, immediately after the
purchase date, such debenture will cease to be outstanding and cash interest and
original issue discount on such debenture will cease to accrue and will be
deemed paid, whether or not such debenture is delivered to the paying agent, and
all other rights of the holder shall terminate, other than the right to receive
the purchase price upon delivery of the debenture.

                                       21
<PAGE>

     No debentures may be purchased for cash at the option of the holders if
there has occurred and is continuing an event of default with respect to the
debentures other than a default in the payment of the purchase price with
respect to such debentures.  If we become obligated to purchase any outstanding
debenture on a purchase date, there can be no assurance that we would have
sufficient funds to pay the purchase price on that purchase date (in which case,
we could be required to issue shares of class B common stock to pay the purchase
price at valuations based on then prevailing market prices) for all the
debentures tendered.  Our then existing senior indebtedness or borrowing
agreements may provide that the maturing of any obligation to purchase the
debentures would constitute an event of default thereunder and may restrict or
prohibit the repurchase of the debentures.

Change In Control Permits Purchase of Debentures at the Option of the Holder

     In the event of any change in control of UHS occurring on or prior to June
23, 2006, each holder will have the right, at the holder's option, subject to
the terms and conditions of the indenture, to require us to purchase all or any
portion of the holder's debentures.  However, debentures submitted for purchase
by a holder must be in principal amounts at maturity of $1,000 or an integral
multiple of $1,000.

     We will be required to purchase the debentures as of the date that is 35
business days after the occurrence of such change in control (a "change in
control purchase date") at a cash price equal to the issue price plus accrued
original issue discount and accrued cash interest to the change in control
purchase date.

     If prior to a change in control purchase date the debentures have been
converted to semiannual coupon debentures following the occurrence of a tax
event, we will be required to purchase the debentures at a cash price equal to
the restated principal amount plus accrued and unpaid interest from the date of
the conversion to, but excluding, the change in control purchase date.

     Within 15 business days after the occurrence of a change in control, we are
obligated to mail to the trustee and to all holders of debentures at their
addresses shown in the register of the registrar and to beneficial owners as
required by applicable law a notice regarding the change in control, which
notice shall state, among other things:

 .  the events causing a change in control;

 .  the date of such change in control;

 .  the last date on which the purchase right may be exercised;

 .  the change in control purchase price;

 .  the change in control purchase date;

 .  the name and address of the paying agent and the conversion agent;

 .  the conversion rate and any adjustments to the conversion rate;

 .  that the debentures with respect to which a change in control purchase notice
   is given by the holder may be converted only if the change in control
   purchase notice has been withdrawn in accordance with the terms of the
   indenture; and

 .  the procedures that holders must follow to exercise these rights.

     We will cause a copy of such notice to be published in The Wall Street
Journal or another daily newspaper of national circulation.

     To exercise this right, the holder must deliver a written notice to the
paying agent prior to the close of business on the change in control purchase
date.  The required purchase notice upon a change in control shall state:

                                       22
<PAGE>

 .  the certificate number of the debentures to be delivered by the holder;

 .  the portion of the principal amount at maturity to be purchased, which
   portion must be $1,000 or an integral multiple of $1,000; and

 .  that we are to purchase such debentures pursuant to the applicable provisions
   of the indenture and the debentures.

     Any change in control purchase notice may be withdrawn by the holder by a
written notice of withdrawal delivered to the paying agent prior to the close of
business on the change in control purchase date.

     The notice of withdrawal shall state:

 .  the principal amount at maturity being withdrawn;

 .  the certificate numbers of the debentures being withdrawn; and

 .  the principal amount at maturity, if any, of the debentures that remain
   subject to a change in control purchase notice.

     Payment of the change in control purchase price for a debenture for which a
change in control purchase notice has been delivered and not validly withdrawn
is conditioned upon delivery of the debenture, together with necessary
endorsements, to the paying agent at any time after the delivery of such change
in control purchase notice.  Payment of the change in control purchase price for
such debenture will be made promptly following the later of the change in
control purchase date or the time of delivery of such debenture.

     If the paying agent holds money or securities sufficient to pay the change
in control purchase price of the debenture on the business day following the
change in control purchase date in accordance with the terms of indenture, then,
immediately after the change in control purchase date, such debenture will cease
to be outstanding and cash interest and original issue discount on such
debenture will cease to accrue and will be deemed paid, whether or not such
debenture is delivered to the paying agent, and all other rights of the holder
shall terminate, other than the right to receive the change in control purchase
price upon delivery of the debenture.

     Under the indenture, a "change in control" of UHS is deemed to have
occurred at such time as:

 .  any person, including its affiliates and associates, other than permitted
   holders, files a Schedule 13D or TO (or any successor schedule, form or
   report under the Exchange Act) disclosing that such person has become the
   beneficial owner of 50% or more of the total voting power in the aggregate of
   all classes of our capital stock then outstanding normally entitled to vote
   in elections of directors, with certain exceptions, or any permitted holder
   files such a schedule, form or report in connection with a transaction or
   event, as a result of which the class B common stock ceases (or, upon
   consummation of or immediately following such transaction or event, will
   cease) to be listed on a United States national securities exchange or
   approved for quotation on the Nasdaq National Market or any similar United
   States system for automated dissemination of quotations of securities prices;
   or

 .  there shall be consummated any consolidation or merger of UHS pursuant to
   which the class B common stock would be converted into cash, securities or
   other property, in each case other than a consolidation or merger of UHS in
   which (1) the holders of all classes of common stock of UHS immediately prior
   to the consolidation or merger have, directly or indirectly, at least a
   majority of the total voting power in the aggregate of all classes of capital
   stock of the continuing or surviving corporation normally entitled to vote in
   elections of directors immediately after the consolidation or merger and (2)
   the shares of class B common stock shall be converted into common stock which
   is (or, upon consummation of or immediately following such consolidation or
   merger, will be) listed on a United States national securities exchange or
   approved for quotation on the Nasdaq

                                       23
<PAGE>

   National Market or any similar United States system for automated
   dissemination of quotations of securities prices.

     For purposes of the foregoing definition, permitted holders means (A) UHS,
any subsidiary of UHS or their employee benefit plans or Alan B. Miller, UHS's
Chairman of the Board, President and Chief Executive Officer, and his spouse,
immediate family members, estate, lineal descendants, executors or
administrators, or (B) any trust, corporation or other entity, the
beneficiaries, stockholders or other persons beneficially holding an 80% or more
controlling interest of which consist of persons or entities referred to in
clause (A).

     In connection with any purchase offer in the event of a change in control,
we will:

 .  comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender
   offer rules under the Exchange Act which may then be applicable; and

 .  file Schedule TO or any other required schedule under the Exchange Act.

     The change in control purchase feature of the debentures may in certain
circumstances make more difficult or discourage a takeover of UHS.  The change
in control purchase feature, however, is not the result of our knowledge of any
specific effort to accumulate shares of our common stock or to obtain control of
UHS by means of a merger, tender offer, solicitation or otherwise, or part of a
plan by management to adopt a series of anti-takeover provisions.

     Instead, the change in control purchase feature is a standard term
contained in offerings of securities comparable to the debentures that have been
marketed by Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith
Incorporated, J.P. Morgan Securities Inc., UBS Warburg LLC and Banc of America
Securities LLC, the initial purchasers of the debentures.  The terms of the
change in control purchase feature resulted from negotiations between the
initial purchasers and us.

     We could, in the future, enter into certain transactions, including certain
recapitalizations, that would not constitute a change in control with respect to
the change in control purchase feature of the debentures but that would increase
the amount of our outstanding indebtedness.

     No debentures may be purchased at the option of holders upon a change in
control if there has occurred and is continuing an event of default with respect
to the debentures, other than a default in the payment of the change in control
purchase price with respect to the debentures.

Optional Conversion to Semiannual Coupon Debenture upon Tax Event


     From and after the date of the occurrence of a tax event, we will have the
option to elect to have interest in lieu of future original issue discount and
regular cash interest accrue at 5.00% per year on a principal amount per
debenture (the "restated principal amount") equal to the issue price plus
original issue discount accrued to the date of the tax event or the date on
which we exercise the option described herein, whichever is later (the "option
exercise date").  Such interest shall accrue from the option exercise date and
shall be payable semiannually on each interest payment date to holders of record
at the close of business on the regular record date immediately preceding such
interest payment date.  Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months and will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the option
exercise date.

     A "tax event" means that UHS shall have received an opinion from
independent tax counsel experienced in such matters to the effect that, on or
after the date of this prospectus, as a result of:

 .  any amendment to, or change (including any announced prospective change) in,
   the laws (or any regulations thereunder) of the United States or any
   political subdivision or taxing authority thereof or therein, or

                                       24
<PAGE>

 .  any amendment to, or change in, an interpretation or application of such laws
   or regulations by any legislative body, court, governmental agency or
   regulatory authority,

in each case which amendment or change is enacted, promulgated, issued or
announced or which interpretation is issued or announced or which action is
taken, on or after the date of this prospectus, there is more than an
insubstantial risk that interest (including original issue discount) payable on
the debentures either:

 .  would not be deductible on a current accrual basis, or

 .  would not be deductible under any other method, in either case in whole or in
   part, by us (by reason of deferral, disallowance, or otherwise) for United
   States federal income tax purposes.

     The Clinton Administration has previously proposed to change the tax law to
defer the deduction of original issue discount on convertible debt instruments
until the issuer pays the interest.  Congress has not yet enacted these proposed
changes in the law.

     If a similar proposal were ever enacted and made applicable to the
debentures in a manner that would limit our ability to either:

 .  deduct the interest, including original issue discount, payable on the
   debentures on a current accrual basis, or

 .  deduct the interest, including original issue discount, payable on the
   debentures under any other method for United States federal income tax
   purposes,

such enactment would result in a tax event and the terms of the debentures would
be subject to modification at our option as described above.

     The modification of the terms of debentures by us upon a tax event as
described above could possibly alter the timing of income recognition by holders
of the debentures with respect to the semiannual payments of interest due on the
debentures after the option exercise date.  See "Federal Income Tax
Considerations."

Merger and Sales of Assets by UHS

     The indenture provides that UHS may not consolidate with or merge into any
other person or convey, transfer or lease its properties and assets
substantially as an entirety to another person, unless among other things, (i)
the resulting, surviving or transferee person (if other than UHS) is organized
and existing under the laws of the United States, any state thereof or the
District of Columbia and such person assumes all of our obligations under the
debentures and the indenture, and (ii) UHS or such successor person shall not
immediately thereafter be in default under the indenture.  Upon the assumption
of our obligations by such a person in such circumstances, subject to certain
exceptions, we shall be discharged from all obligations under the debentures and
the indenture.  Although such transactions are permitted under the indenture,
certain of the foregoing transactions occurring on or prior to June 23, 2006
could constitute a change in control of UHS permitting each holder to require us
to purchase its debentures as described above.

Events of Default; Notice and Waiver

     The indenture provides that, if an event of default with respect to the
debentures shall have occurred and be continuing, either the trustee or the
holders of not less than 25% in aggregate principal amount at maturity of the
debentures then outstanding may declare the issue price plus original issue
discount accrued, together with any accrued cash interest (or if the debentures
have been converted to semiannual coupon debentures following a tax event, the
restated principal amount, plus accrued interest) to the date of such
declaration (in the case of an event of default specified in the first six
bullet points of the following paragraph) or to the date of default (in the case
of an event of default specified in the last bullet point of the following
paragraph) on all the debentures to be immediately due and payable.  In the case
of certain events of bankruptcy or insolvency, the issue price of the debentures
plus the

                                       25
<PAGE>

original issue discount accrued thereon, together with any accrued cash
interest (or if the debentures have been converted to semiannual coupon
debentures following a tax event, the restated principal amount, plus accrued
interest) to the occurrence of such event shall automatically become and be
immediately due and payable.  Under certain circumstances, the holders of a
majority in aggregate principal amount at maturity of the outstanding debentures
may rescind any such acceleration with respect to the debentures and its
consequences.  Interest shall accrue and be payable on demand upon a default in
the payment of the principal amount at maturity (or, if the debentures have been
converted to semiannual coupon debentures following a tax event, the restated
principal amount), accrued original issue discount, cash interest when due,
redemption price, purchase price, change in control purchase price or shares of
class B common stock (or cash in lieu of fractional shares) to be delivered on
conversion of debentures, in each case to the extent that the payment of such
interest shall be legally enforceable.  The accrual of such interest on overdue
amounts shall be in lieu of, and not in addition to, the continued accrual of
original issue discount.

     The following will be events of default with respect to the debentures:

 .  default in payment of the principal amount at maturity (or, if the debentures
   have been converted to semiannual coupon debentures following a tax event,
   the restated principal amount), accrued original issue discount, cash
   interest when due (if such default in payment of interest shall continue for
   30 days), redemption price, purchase price or change in control purchase
   price with respect to any debenture, when the same becomes due and payable;

 .  our failure to deliver shares of class B common stock (together with cash in
   lieu of fractional shares) when such class B common stock (or cash in lieu of
   fractional shares) is required to be delivered following conversion of a
   debenture and continuance of such default for 10 days;

 .  our failure to comply with any of our other agreements in the debentures or
   the indenture upon the receipt by us of notice of such default from the
   trustee or from holders of not less than 25% in aggregate principal amount at
   maturity of the debentures then outstanding and our failure to cure such
   default within 30 days after receipt by us of such notice;

 .  acceleration of Indebtedness (as defined in the indenture) of UHS or any
   Significant Subsidiary (as defined in the indenture) under the terms of the
   instruments evidencing such Indebtedness aggregating more than $5 million at
   the time outstanding;

 .  a default in the payment of principal and interest in respect of any
   Indebtedness of UHS or any Significant Subsidiary having an outstanding
   principal amount of $5 million individually or in the aggregate;

 .  judgments for the payment of more than $5 million at the time outstanding
   rendered against UHS or any Significant Subsidiary and not discharged within
   60 days after such judgment becomes final and non-appealable; and

 .  certain events of bankruptcy, insolvency or reorganization with respect to
   UHS or any Significant Subsidiary.

     The trustee shall, within 90 days after the occurrence of any default, mail
to all holders of the debentures notice of all defaults of which the trustee
shall be aware, unless such defaults shall have been cured or waived before
giving of such notice; provided, that the trustee may withhold such notice as to
any default other than a payment default, if it determines in good faith that
withholding the notice is in the interests of the holders.

     The holders of a majority in aggregate principal amount at maturity of the
outstanding debentures may direct the time, method and place of conducting any
proceeding for any remedy available to the trustee or exercising any trust or
power conferred on the trustee, provided that such direction shall not be in
conflict with any law or the indenture and subject to certain other limitations.
The trustee may refuse to perform any duty or exercise any right or power or
extend or risk its own funds or otherwise incur any financial liability unless
it receives indemnity

                                       26
<PAGE>

satisfactory to it against any loss, liability or expense. No holder of any
debenture will have any right to pursue any remedy with respect to the indenture
or the debentures, unless:

 .  such holder shall have previously given the trustee written notice of a
   continuing event of default;

 .  the holders of at least 25% in aggregate principal amount at maturity of the
   outstanding debentures shall have made a written request to the trustee to
   pursue such remedy;

 .  such holder or holders shall have offered to the trustee reasonable security
   or indemnity against any loss, liability or expense satisfactory to it;

 .  the trustee shall have failed to comply with the request within 60 days after
   receipt of such notice, request and offer of security or indemnity; and

 .  the holders of a majority in aggregate principal amount at maturity of the
   outstanding debentures shall not have given the trustee a direction
   inconsistent with such request within 60 days after receipt of such request.

     The right of any holder (1) to receive payment of the principal amount at
maturity (or, if the debentures have been converted to semiannual coupon
debentures following a tax event, the restated principal amount), issue price,
accrued original issue discount, redemption price, purchase price, change in
control purchase price or interest in respect of the debentures held by such
holder on or after the respective due dates expressed in the debentures, (2) to
convert such debentures, or (3) to bring suit for the enforcement of any such
payment on or after such respective dates or the right to convert, shall not be
impaired or adversely affected without such holder's consent.

     The holders of a majority in aggregate principal amount at maturity of
debentures at the time outstanding may waive any existing default and its
consequences except (1) any default in any payment on the debentures, (2) any
default with respect to the conversion rights of the debentures, or (3) any
default in respect of certain covenants or provisions in the indenture which may
not be modified without the consent of the holder of each debenture as described
in "--Modification" below.

     We will be required to furnish to the trustee annually a statement as to
any default by us in the performance and observance of our obligations under the
indenture.  In addition, we must file with the trustee written notice of the
occurrence of any default or event of default within five business days of our
becoming aware of such default or event of default.

Modification

     Modification and amendment of the indenture or the debentures may be
effected by UHS and the trustee with the written consent of the holders of not
less than a majority in aggregate principal amount at maturity of the debentures
then outstanding.  However, without the consent of each holder affected thereby,
no amendment may, among other things:

 .  reduce the principal amount at maturity, restated principal amount, issue
   price, purchase price, change in control purchase price or redemption price
   with respect to any debenture, or extend the stated maturity of any debenture
   or alter the manner or rate of accrual of original issue discount or cash
   interest or make any debenture payable in money or securities other than that
   stated in the debenture;

 .  make any reduction in the principal amount at maturity of debentures whose
   holders must consent to an amendment or any waiver under the indenture or
   modify the indenture provisions relating to such amendments or waivers;

 .  make any change that adversely affects the right to convert any debenture or
   the right to require us to purchase a debenture; or

                                       27
<PAGE>

 .  impair the right to institute suit for the enforcement of any payment with
   respect to, or conversion of, the debentures.

   Without the consent of any holder of debentures, we and the trustee may
amend the indenture to:

 .  cure any ambiguity, omission, defect or inconsistency, provided, however,
   that such amendment does not materially adversely affect the rights of any
   holder;

 .  provide for the assumption by a successor to UHS of our obligations under the
   indenture and debentures;

 .  provide for uncertificated debentures in addition to certificated debentures,
   as long as such uncertificated debentures are in registered form for United
   States federal income tax purposes;

 .  make any change that does not adversely affect the rights of any holder of
   debentures;

 .  make any change to comply with the Trust Indenture Act of 1939, or to comply
   with any requirement of the SEC in connection with the qualification of the
   indenture under the Trust Indenture Act of 1939; or

 .  add to our covenants or obligations under the indenture for the protection of
   holders of the debentures or surrender any right, power or option conferred
   by the indenture on UHS.

Discharge of the Indenture

     We may satisfy and discharge our obligations under the indenture by
delivering to the trustee for cancellation all outstanding debentures or by
depositing with the trustee, the paying agent or the conversion agent, if
applicable, after the debentures have become due and payable, whether at stated
maturity or any redemption date, or any purchase date, or a change in control
purchase date, or upon conversion or otherwise, cash or shares of class B common
stock (as applicable under the terms of the indenture) sufficient to pay all of
the outstanding debentures and paying all other sums payable under the indenture
by us.

Limitations of Claims in Bankruptcy

     If a bankruptcy proceeding is commenced in respect of UHS, the claim of the
holder of a debenture under Title 11 of the United States Code, is limited to
the issue price of the debenture plus that portion of the original issue
discount, together with any cash interest (or, if the debentures have been
converted to semiannual coupon debentures following a tax event, the restated
principal amount, plus interest), that is deemed to have accrued from the date
of issue to the commencement of the proceeding.  In addition, the holders of the
debentures will be effectively subordinated to the indebtedness and other
obligations of our subsidiaries.

Governing Law

     The indenture and the debentures will be governed by, and construed in
accordance with, the laws of the State of New York.

Information Concerning the Trustee

     The trustee is Bank One Trust Company, N.A.  The trustee is a lender to us
under our revolving credit agreement, provides cash management and depository
account services to us, and is the trustee under our indenture entered into with
our shelf registration for the issuance from time to time of debt securities of
up to $500 million.  No such debt securities have been issued to date.  From
time to time, we may enter into other banking relationships with the trustee.

                                       28

Registration Rights

     We entered into a registration rights agreement with the initial purchasers
of the debentures. If you sell debentures or class B common stock issued upon
conversion of the debentures under this registration statement, you generally
will be required to be named as a selling securityholder in this prospectus,
deliver this prospectus to purchasers and be bound by applicable provisions of
the registration rights agreement, including some indemnification provisions.

     In the registration rights agreement, we agreed to file a registration
statement that includes this prospectus with the SEC by September 21, 2000. We
agreed to use reasonable efforts to cause this registration statement to become
effective as promptly as practicable, but by December 20, 2000. Under the
registration rights agreement, we are obligated to use reasonable efforts to
keep the registration statement effective until the earlier of: (1) two years
from the date on which this registration statement is declared effective by the
SEC, (2) the date on which all securities offered under this prospectus have
been sold pursuant to this prospectus, and (3) the date on which all outstanding
securities held by non-affiliates of UHS may be resold without registration
under the Securities Act pursuant to Rule 144(k) under the Securities Act. We
may suspend the use of this prospectus under limited circumstances, including
pending corporate developments or public filings with the SEC, for a period not
to exceed 45 days in any 3-month period and 90 days in any 12-month period. We
also agreed to pay liquidated damages to holders of debentures and shares of
class B common stock issued upon conversion of the debentures if the
registration statement is not timely filed or made effective or if the
prospectus is unavailable for periods in excess of those permitted above. You
should refer to the indenture for a description of these liquidated damages.

                         DESCRIPTION OF CAPITAL STOCK

     UHS's authorized capital stock consists of 12,000,000 shares of class A
common stock, $0.01 par value per share, 75,000,000 shares of class B common
stock, $0.01 par value per share, 1,200,000 shares of class C common stock,
$0.01 par value per share, and 5,000,000 shares of class D common stock, $0.01
par value per share.  Shares of class A, C and D common stock may be converted
into class B common stock on a share-for-share basis.

     UHS's class B common stock currently trades on the New York Stock Exchange
under the symbol "UHS".

     Class A common stock, class B common stock, class C common stock and class
D common stock are substantially similar except that each class has different
voting rights.  Each share of class A common stock has one vote per share; each
share of class B common stock has one-tenth vote per share; each share of class
C common stock has one hundred votes per share; and each share of class D common
stock has ten votes per share.  Notwithstanding the foregoing, if a holder of
class C or class D common stock holds a number of shares of class A or class B
common stock, respectively, which is less than ten times the number of shares of
class C or class D common stock, respectively, that such holder holds, then such
holder will only be entitled to one vote per share of class C common stock and
one-tenth vote per share of class D common stock.

     The holders of class B and class D common stock, voting together, with each
share of class B and class D common stock having one vote per share, are
entitled to elect the greater of 20% of UHS's Board of Directors or one
director.  The holders of class B and class D common stock are also permitted to
vote together as a separate class with respect to certain other matters or as
required by applicable law.  Holders of class A and class C common stock, voting
as a single class, elect the remaining directors and vote together with the
holders of class B and class D common stock on all other matters.

                       FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of United States federal income tax
considerations relating to the purchase, ownership, disposition, and conversion
of debentures.  Unless otherwise stated, this summary deals only with debentures
held as capital assets (generally, assets held for investment under the Internal
Revenue Code of 1986, as amended (the "Code")) by a holder who purchases
debentures upon original issuance and who is, for United States federal income
tax purposes:

                                       29
<PAGE>

 .  a citizen or resident of the United States;

 .  a corporation created or organized in or under the laws of the United States
   or any of its political subdivisions;

 .  an estate, the net income of which is subject to United States federal income
   taxation regardless of its source; or

 .  a trust, the administration of which is subject to the primary supervision of
   a court within the United States and which has one or more United States
   persons (as defined in the Code) with authority to control all substantial
   decisions.

     The tax treatment of a holder of debentures may vary depending on his
particular situation.  This summary does not address all of the tax consequences
that may be relevant to holders who may be subject to special tax rules such as,
for example, rules relating to persons who are not citizens or residents of the
United States; banks and financial institutions; insurance companies; broker-
dealers; tax-exempt organizations; and persons who hold debentures as part of a
hedging, conversion or constructive sale transaction, straddle or other risk
reduction transaction.  In addition, this summary does not address any aspects
of state, local or foreign tax laws.

     Furthermore, this discussion does not address the tax consequences
applicable to holders that are treated as partnerships or as other pass through
entities for United States federal income tax purposes.  This summary is based
on the United States federal income tax law in effect as of the date hereof,
which is subject to change, possibly on a retroactive basis.  There can be no
assurance that the Internal Revenue Service will not challenge one or more of
the conclusions described herein, and we have not obtained, nor do we intend to
obtain, a ruling from the Internal Revenue Service with respect to the United
States federal income tax consequences of acquiring or holding debentures.  An
investor considering the purchase of debentures should consult his tax advisor
as to the particular tax consequences of purchasing, owning, and disposing of
debentures, including the application and effect of United States federal,
state, local, and foreign tax laws.

Tax Opinion

     We have received an opinion from our counsel, Fulbright & Jaworski L.L.P.,
that, subject to the qualifications and assumptions contained therein, the
debentures will be treated as indebtedness for United States federal income tax
purposes.

Cash Interest and Original Issue Discount

     The debentures were initially issued at a substantial discount from their
stated principal amount at maturity.  For United States federal income tax
purposes, the excess of the stated principal amount at maturity of each
debenture over the issue price (the initial offering price at which the
debentures were sold to the initial purchasers of the debentures) constitutes
original issue discount.  In addition to stated cash interest on a debenture,
which will be taxable to a holder as ordinary interest income at the time it
accrues or is paid depending on the holder's method of accounting for United
States federal income tax purposes, holders of debentures will be required to
include original issue discount in income periodically over the term of the
debentures before receipt of the cash or other payment attributable to such
income.  For United States federal income tax purposes, each holder of a
debenture must generally include in gross income a portion of the original issue
discount in each taxable year during which the debenture is held in an amount
equal to the original issue discount that accrues on the debenture during such
period, determined by using a constant yield to maturity method.  The original
issue discount included in income for each year will be calculated under a
compounding formula that will result in the allocation of less original issue
discount to the earlier years of the term of the debenture and more original
issue discount to later years.  Any amount included in income as original issue
discount will increase the holder's tax basis in the debenture.

                                       30
<PAGE>

Disposition or Conversion of Debentures

     Except as described below, upon the sale or other disposition of a
debenture, a holder will recognize gain or loss equal to the difference between
the amount realized and the holder's income tax basis in the debenture, which
will generally equal the holder's cost of the debenture increased by any accrued
original issue discount includible in such holder's gross income and reduced by
any payments other than payments of cash interest.  Gain or loss upon a sale or
other disposition of a debenture will generally be capital gain or loss and will
be long-term capital gain or loss if the debenture is held for more than one
year.

     A holder that receives class B common stock in exchange for a debenture
(whether upon conversion of a debenture or at our option upon tender of a
debenture) will generally not recognize gain or loss (except with respect to
shares, if any, received in respect of accrued cash interest, which will be
treated as a payment of interest, and cash received in lieu of a fractional
share).  A holder's income tax basis in the class B common stock received on
conversion or tender of a debenture will be the same as the holder's adjusted
income tax basis in the debenture at the time of conversion or tender (exclusive
of any basis allocable to a fractional share), and the holding period for the
class B common stock received on conversion or tender will include the holding
period of the debenture converted.  It is possible, however, the Internal
Revenue Service may argue that the holding period of the class B common stock
allocable to accrued original issue discount will commence on the date of the
conversion.  The receipt of cash in lieu of a fractional share of class B common
stock will generally result in capital gain or loss, measured by the difference
between the cash received for the fractional share and the holder's adjusted tax
basis in the fractional share.

     If a holder elects to exercise his option to cause us to purchase his
debentures on a purchase date and we issue class B common stock in satisfaction
of all the purchase price, such exchange will be treated the same as a
conversion.  If a holder elects to exercise his option to cause us to purchase
his debentures on a purchase date and we deliver a combination of cash and class
B common stock in satisfaction of the purchase price, gain, but not loss,
realized by the holder will generally be recognized, but only to the extent of
all cash received.  The character of any gain recognized may be capital or
ordinary depending on the circumstances, including the extent to which a holder
actually or constructively has any other equity interest in UHS.  (The holder's
gain realized will be the sum of any cash received (other than cash attributable
to accrued but unpaid stated interest) and the fair market value of the class B
common stock received reduced by the holder's adjusted tax basis in the
debentures.) A holder's income tax basis in the class B common stock received
will generally be the same as the holder's income tax basis in the debenture,
reduced by the cash received and increased by any gain recognized (exclusive of
any income tax basis allocable to a fractional share).  In the event a holder
surrenders a debenture for conversion at such a time that the debenture is
required to be accompanied by a payment in an amount equal to the interest due
thereon on the immediately next succeeding interest payment date, the holder,
particularly if an accrual method taxpayer, should consult with its tax advisor
regarding the extent to which such payment is deductible.

Adjustment of Conversion Price

     If at any time we make a distribution of property to stockholders that
would be taxable to such stockholders as a dividend for United States federal
income tax purposes (for example, distributions of evidences of indebtedness or
assets of UHS, but generally not stock dividends or rights to subscribe for
class B common stock) and, in accordance with the anti-dilution provisions of
the debentures, the conversion rate of the debentures is increased, the amount
of such increase may be deemed to be the payment of a taxable dividend to
holders of the debentures.  If the conversion rate is increased at our
discretion or in other circumstances as described under the heading "Description
of Debentures," such increase may also be deemed to be the payment of a taxable
dividend to holders of debentures.  Moreover, in certain other circumstances,
the absence of such an adjustment to the conversion rate may result in a taxable
dividend to holders of class B common stock.

Tax Event

     The modification of the terms of the debentures by us upon a tax event as
described in "Description of Debentures--Optional Conversion to Semiannual
Coupon Debenture upon Tax Event," could possibly alter the timing of income
recognition by the holders of the debentures with respect to the semiannual
payments of interest due on the debentures after the option exercise date.

Backup Withholding and Information Reporting

     Information reporting will apply to payments of interest or dividends, if
any, made by us on, or the proceeds of the sale or other disposition of, the
debentures or shares of class B common stock with respect to certain
noncorporate holders, and backup withholding at a rate of 31% may apply unless
the recipient of such payment supplies a taxpayer identification number,
certified under penalties of perjury, as well as certain other information or
otherwise establishes an exemption from backup withholding.  Any amount withheld
under the backup withholding rules will be allowable as a credit against the
holder's United States federal income tax, provided that the required
information is provided to the Internal Revenue Service.

                            SELLING SECURITYHOLDERS

     The following table presents information with respect to the selling
securityholders and the principal amounts of debentures and shares of our class
B common stock issuable upon the conversion of these debentures that they may
offer under this prospectus.  The term "selling securityholders" includes
transferees, pledgees, donees and successors of holders selling securities
received from a named selling securityholder after the date of this prospectus.
The debentures were originally issued by us and sold by the initial purchasers,
in transactions exempt from the registration requirements of the Securities Act,
to qualified institutional buyers or to institutional "accredited investors."
To our knowledge, none of the selling securityholders has, or within the past
three years has had, any position, office or other material relationship with us
or any of our predecessors or affiliates, except that Merrill Lynch, Pierce,
Fenner & Smith Incorporated, J.P. Morgan Securities Inc. and Banc of America
Securities LLC were initial purchasers of the debentures.

     The principal amounts of debentures provided in the table below is based on
information provided to us by each of the selling securityholders on or prior to
October 30, 2000, and the percentages are based on $586,992,000 principal amount
at maturity of debentures outstanding.  The number of shares of class B common
stock that may be sold is calculated based on the current conversion ratio of
5.6024 shares of class B common stock per $1,000 principal amount at maturity of
a debenture.  If each selling securityholder named below converted all of its
debentures, each would own less than 1% of our outstanding class B common stock,
based on 27,865,334 shares of class B common stock issued and outstanding as of
June 30, 2000.

     Since the date on which each provided this information, each selling
securityholder identified below may have sold, transferred or otherwise disposed
of all or a portion of its debentures in a transaction exempt from the
registration requirements of the Securities Act.  Information concerning the
selling securityholders may change from time to time and any changed information
will be set forth in supplements to this prospectus to the extent required.  In
addition, the conversion ratio, and therefore the number of shares of our class
B common stock issuable upon conversion of the debentures, is subject to
adjustment.  Accordingly, the number of shares of class B common stock issuable
upon conversion of the debentures may increase or decrease.

     The selling securityholders may from time to time offer and sell any or all
of the securities under this prospectus.  Because the selling securityholders
are not obligated to sell the debentures or the class B common stock issuable
upon the conversion of the debentures, we cannot estimate the amount of the
debentures or how many shares of our class B common stock that each selling
securityholder will beneficially own after this offering.

                             PLAN OF DISTRIBUTION

     The selling securityholders will be offering and selling all securities
offered and sold under this prospectus. We will not receive any of the proceeds
on these sales of these securities.  In connection with the initial offering of
the debentures, we entered into a registration rights agreement dated June 23,
2000 with the initial purchasers of the debentures.  Securities may only be
offered or sold under this prospectus pursuant to the terms of the registration
rights agreement.  However, selling securityholders may resell all or a portion
of the securities in open market transactions in reliance upon Rule 144 or Rule
144A under the Securities Act, provided they meet the criteria and conform to
the requirements of one of these rules.

Who May Sell and Applicable Restrictions

     The securities may be sold directly by the selling securityholders from
time to time.  The selling securityholders may decide not to sell any of the
securities offered under this prospectus, and selling securityholders could
transfer, devise or gift these securities by other means.

     Alternatively, the selling securityholders may from time to time offer the
securities through brokers, dealers or agents that may receive compensation in
the form of discounts, concessions or commissions from the selling
securityholders and/or the purchasers of the securities for whom they may act as
agent.  In effecting sales, broker-dealers that are engaged by the selling
securityholders may arrange for other broker-dealers to participate.  The
selling securityholders and any brokers, dealers or agents who participate in
the distribution of the securities may be deemed to be underwriters and any
profits on the sale of the securities by them and any discounts, commissions or
concessions received by any broker, dealer or agent might be deemed to be
underwriting discounts and commissions under the Securities Act.  To the extent
the selling securityholders may be deemed to be underwriters, the selling
securityholders may be subject to statutory liabilities, including, but not
limited to, liability under Sections 11, 12 and 17 of the Securities Act and
Rule 10b-5 under the Exchange Act.

Prospectus Delivery

     Because selling securityholders may be deemed to be underwriters within the
meaning of Section 2(11) of the Securities Act, they will be subject to the
prospectus delivery requirements of the Securities Act.  At any time a
particular offer of the securities is made, a revised prospectus or prospectus
supplement, if required, will be distributed which will disclose:

  .  the name of the selling securityholders and of any participating
     underwriters, broker-dealers or agents;

  .  the aggregate amount and type of securities being offered;

  .  the price at which the securities were sold and other material terms of the
     offering;

  .  any discounts, commissions, concessions or other items constituting
     compensation from the selling securityholders and any discounts,
     commissions or concessions allowed or reallowed or paid to dealers; and

  .  that the participating broker-dealers did not conduct any investigation to
     verify the information in this prospectus or incorporated in this
     prospectus by reference.

The prospectus supplement or a post-effective amendment will be filed with the
SEC to reflect the disclosure of additional information with respect to the
distribution of the securities.

Manner of Sales

     The selling securityholders will act independently of us in making
decisions with respect to the timing, manner and size of each sale.  Sales may
be made over the New York Stock Exchange (in the case of the class B common
stock) or in the over-the-counter market.  The securities may be sold at then
prevailing market prices, at fixed prices or at negotiated prices.

     The securities may be sold according to one or more of the following
methods:

     .  a block trade in which the broker or dealer so engaged will attempt to
        sell the securities as agent but may position and resell a portion of
        the block as principal to facilitate the transaction;

     .  purchases by a broker or dealer as principal and resale by the broker or
        dealer for its account as allowed under this prospectus;

     .  ordinary brokerage transactions and transactions in which the broker
        solicits purchasers;

     .  an exchange distribution under the rules of the exchange;

     .  face-to-face transactions between sellers and purchasers without a
        broker-dealer; and

     .  by writing options.

     Some persons participating in the offering may engage in transactions that
stabilize, maintain or otherwise affect the price of the securities including
the entry of stabilizing bids or syndicate covering transactions or the
imposition of penalty bids.

     The selling securityholders and any other person participating in a
distribution will be subject to applicable provisions of the Exchange Act and
the rules and regulations thereunder including Regulation M.  This regulation
may limit the timing of purchases and sales of any of the securities by the
selling securityholders and any other person.  The anti-manipulation rules under
the Exchange Act may apply to sales of securities in the market and to the
activities of the selling securityholders and their affiliates.  Furthermore,
Regulation M of the Exchange Act may restrict the ability of any person engaged
in the distribution of the securities to engage in market-making activities with
respect to the particular securities being distributed for a period of up to
five business days before the distribution.  All of the foregoing may affect the
marketability of the securities and the ability of any person or entity to
engage in market-making activities with respect to the securities.

Hedging and Other Transactions With Broker-Dealers

     In connection with distributions of the securities, the selling
securityholders may enter into hedging transactions with broker-dealers.  In
connection with these transactions, broker-dealers may engage in short sales of
the registered securities in the course of hedging the positions they assume
with selling securityholders.  The selling securityholders may also sell
securities short and redeliver the securities to close short positions.  The
selling securityholders may also enter into options or other transactions with
broker-dealers which require the delivery to the broker-dealer of the registered
securities.  The broker-dealer may then resell or transfer these securities
under this prospectus.  A selling securityholder may also loan or pledge the
registered securities to a broker-dealer and the broker-dealer may sell the
securities so loaned or, upon a default, the broker-dealer may effect sales of
the pledged securities under this prospectus.

Expenses Associated With Registration

     We have agreed to pay substantially all of the expenses of registering the
securities under the Securities Act and of compliance with blue sky laws,
including registration and filing fees, printing and duplicating expenses, legal
fees of our counsel, fees for one legal counsel retained by the selling
securityholders and fees of the trustee under the indenture pursuant to which we
originally issued the securities and of the registrar and transfer agent of the
class B

                                       36

common stock. If the debentures or the class B common stock into which the
debentures may be converted are sold through underwriters or broker-dealers, the
selling securityholders will be responsible for underwriting discounts,
underwriting commissions and agent commissions.

Indemnification and Contribution

     In the registration rights agreement, we and the selling securityholders
have agreed to indemnify or provide contribution to each other and specified
other persons against some liabilities in connection with the offering of the
securities, including liabilities arising under the Securities Act.  The selling
securityholders may also agree to indemnify any broker-dealer or agent that
participates in transactions involving sales of the securities against some
liabilities, including liabilities that arise under the Securities Act.

Suspension of This Offering

     We may suspend the use of this prospectus if we learn of any event that
causes this prospectus to include an untrue statement of a material fact
required to be stated in the prospectus or necessary to make the statements in
the prospectus not misleading in the light of the circumstances then existing.
If this type of event occurs, a prospectus supplement or post-effective
amendment, if required, will be distributed to each selling securityholder. Each
selling securityholder has agreed not to trade securities from the time the
selling securityholder receives notice from us of this type of event until the
selling securityholder receives a prospectus supplement or amendment. This time
period will not exceed 45 days in any 3-month period and 90 days in any 12-month
period.

Termination of This Offering

     Under the registration rights agreement, we are obligated to use reasonable
efforts to keep the registration statement effective until, and therefore this
offering will terminate on, the earlier of:  (1) two years from the date on
which this registration statement is declared effective by the SEC, (2) the date
on which all securities offered under this prospectus have been sold pursuant to
this prospectus, and (3) the date on which all outstanding securities held by
non-affiliates of UHS may be resold without registration under the Securities
Act pursuant to Rule 144(k) under the Securities Act.
