                                                                 March 19, 1997

Dear Shareholder:

     You are cordially invited to attend a Special Meeting of Shareholders of
Universal Hospital Services, Inc. ("UHS"), to be held on Friday, April 4, 1997
at the Radisson South, 7800 Normandale Boulevard, Bloomington, Minnesota,
commencing at 9:00 a.m., Central Time (the "Special Meeting").

     At the Special Meeting, you will be asked to consider and vote on a
proposal to approve the merger (the "Merger") of UHS with a newly formed wholly-
owned indirect subsidiary of MEDIQ Incorporated ("MEDIQ"), in which UHS will
become a wholly-owned indirect subsidiary of MEDIQ and shareholders of UHS will
receive $17.50 per share in cash in exchange for their UHS common stock
(together with the associated Rights (as defined in the accompanying Proxy
Statement) other than (i) shares as to which dissenters' rights are perfected as
described in the Proxy Statement and (ii) any shares owned directly or
indirectly by MEDIQ).

     The Special Committee of the Board of Directors of UHS (the "Special
Committee") has unanimously adopted and approved the Merger and unanimously
recommends that you vote in favor of the Merger at the Special Meeting. The
Special Committee has received a written opinion from Piper Jaffray Inc., its
financial advisor, to the effect that the merger consideration of $17.50 per
share to be paid to the UHS shareholders is fair from a financial point of view
as of March 18, 1997. 

     The Merger and certain related matters are described in detail in the
accompanying Proxy Statement. See "THE MERGER" in the Proxy Statement. A copy of
the Agreement and Plan of Merger is attached as Appendix A to the Proxy
Statement.

     Approval of the matters related to the Merger to be voted on at the Special
Meeting requires the affirmative vote of the holders of a majority of the
outstanding shares of UHS common stock. Accordingly, failure to vote or
abstentions will have the effect of a vote against the Merger for the purpose of
determining whether approval by the holders of a majority of the outstanding
shares of UHS common stock is obtained. Moreover, brokers cannot vote at the
Special Meeting without instructions from shareholders entitled to vote at the
Special Meeting. Shareholders whose shares are held in brokerage accounts
("street names") are urged to instruct their brokers to vote their shares in
favor of the Merger.

     IT IS IMPORTANT THAT YOUR SHARES BE REPRESENTED AT THE SPECIAL MEETING. WE
URGE YOU TO COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD AT YOUR
EARLIEST CONVENIENCE IN THE ENCLOSED POSTAGE-PREPAID ENVELOPE, WHETHER OR NOT
YOU PLAN TO ATTEND THE SPECIAL MEETING. YOUR SHARES OF UHS COMMON STOCK WILL BE
VOTED IN ACCORDANCE WITH THE INSTRUCTIONS YOU HAVE GIVEN IN YOUR PROXY. IF NO
INSTRUCTIONS ARE GIVEN ON YOUR PROXY, THE SHARES REPRESENTED BY THE PROXY WILL
BE VOTED AT THE SPECIAL MEETING FOR APPROVAL OF THE MERGER AND IN ACCORDANCE
WITH THE PROXY STATEMENT ON ANY OTHER BUSINESS THAT MAY PROPERLY COME BEFORE THE
SPECIAL MEETING OR ANY ADJOURNMENTS OR POSTPONEMENTS THEREOF. IF YOU DO NOT
RETURN THE ACCOMPANYING FORM OF PROXY, YOUR SHARES WILL NOT BE VOTED IN FAVOR OF
APPROVAL OF THE MERGER AND WILL HAVE THE SAME EFFECT AS A NO VOTE. IF YOU ATTEND
THE SPECIAL MEETING, YOU MAY VOTE IN PERSON IF YOU WISH, EVEN THOUGH YOU HAVE
PREVIOUSLY RETURNED YOUR PROXY CARD. YOUR PROMPT COOPERATION WILL BE GREATLY
APPRECIATED.


                                  Thomas A. Minner

                                PROXY STATEMENT

                        SPECIAL MEETING OF SHAREHOLDERS
                      To Be Held on Friday, April 4, 1997


     This Proxy Statement is being furnished to the shareholders of Universal
Hospital Services, Inc. ("UHS" or the "Company") in connection with a special
meeting of shareholders of UHS (the "Special Meeting") to be held on Friday,
April 4, 1997 at 9:00 a.m., Central Time, at the Radisson Hotel South, 7800
Normandale Boulevard, Bloomington, Minnesota. The accompanying proxy is being
solicited by UHS's Board of Directors and is to be voted at the Special Meeting
or at any adjournments or postponements thereof.

     At the Special Meeting, holders of shares of common stock of UHS, $.01 par
value per share ("UHS Common Stock"), will consider and vote upon a proposal to
approve and adopt an Agreement and Plan of Merger, dated as of February 10, 1997
(the "Merger Agreement"), by and among UHS, MEDIQ Incorporated, a Delaware
corporation ("MEDIQ"), and PRN Merger Corporation, a Minnesota corporation and a
wholly-owned indirect subsidiary of MEDIQ ("Merger Sub"), which approval and
adoption will also constitute approval of the transactions contemplated thereby.
A copy of the Merger Agreement is attached as Appendix A to this Proxy
Statement.

     The Merger Agreement provides that Merger Sub will be merged with and into
UHS (the "Merger"), with UHS being the surviving corporation after the Merger.
In the Merger, each outstanding share of UHS Common Stock (together with the
associated Rights (as defined herein) and other than (i) shares to which
dissenters' rights are perfected and (ii) any shares owned directly or
indirectly by MEDIQ) will be converted into the right to receive a cash payment
of $17.50 (the "Merger Consideration"). As a result of the Merger, UHS will
become a wholly-owned indirect subsidiary of MEDIQ, and the UHS shareholders who
do not perfect dissenters' rights shall receive the Merger Consideration,
without interest, in exchange for their shares of UHS Common Stock.

     Approval of the matters related to the Merger to be voted on at the Special
Meeting requires the affirmative vote of the holders of a majority of the
outstanding shares of UHS Common Stock. Accordingly, failure to vote or
abstentions will have the effect of a vote against the Merger for the purpose of
determining whether approval by the holders of a majority of the outstanding
shares of UHS Common Stock is obtained. Moreover, brokers cannot vote at the
Special Meeting without instructions from shareholders entitled to vote at the
Special Meeting. Shareholders whose shares are held in brokerage accounts
("street names") are urged to instruct their brokers to vote their shares in
favor of the Merger. Certain members of UHS management, who collectively own
approximately 16.0% of the outstanding shares of UHS Common Stock, have agreed
to vote all of their shares in favor of the Merger at the Special Meeting.

<PAGE>
 
     HOLDERS OF UHS COMMON STOCK WHO COMPLY WITH THE REQUIREMENTS OF SECTIONS
302A.471 AND 302A.473 OF THE MINNESOTA BUSINESS CORPORATION ACT (THE "MBCA") ARE
ENTITLED TO ASSERT DISSENTERS' RIGHTS WITH RESPECT TO THE PROPOSED MERGER AND TO
OBTAIN PAYMENT OF THE FAIR VALUE OF THEIR SHARES IF THE PROPOSED MERGER IS
CONSUMMATED. IN ORDER TO PERFECT DISSENTERS' RIGHTS, A SHAREHOLDER MUST SEND A
NOTICE TO THE CORPORATION BEFORE THE DATE OF THE VOTE AND MUST NOT VOTE IN FAVOR
OF THE MERGER BY PROXY OR OTHERWISE. A COPY OF SECTIONS 302A.471 AND 302A.473 OF
THE MBCA IS ATTACHED TO THE PROXY STATEMENT AS APPENDIX C. SEE "RIGHTS OF
DISSENTING SHAREHOLDERS."

REPRESENTATIONS OTHER THAN THOSE CONTAINED IN THIS PROXY STATEMENT IN CONNECTION
WITH THE SOLICITATION OF PROXIES AND, IF GIVEN OR MADE, SUCH INFORMATION OR
REPRESENTATIONS MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED BY UHS OR
MEDIQ. THIS PROXY STATEMENT DOES NOT CONSTITUTE THE SOLICITATION OF A PROXY IN
ANY JURISDICTION WHERE, OR TO ANY PERSON TO WHOM, IT IS UNLAWFUL TO MAKE SUCH
SOLICITATION. THE DELIVERY OF THIS PROXY STATEMENT SHALL NOT, UNDER ANY
CIRCUMSTANCES, CREATE AN IMPLICATION THAT THERE HAS BEEN NO CHANGE IN THE
AFFAIRS OF UHS OR MEDIQ SINCE THE DATE HEREOF OR THAT THE INFORMATION CONTAINED
HEREIN IS CORRECT AS OF ANY TIME SUBSEQUENT TO THE DATE HEREOF. NEITHER UHS NOR
MEDIQ UNDERTAKES ANY OBLIGATION TO UPDATE THE INFORMATION CONTAINED HEREIN

                                    SUMMARY

     The following is a summary of certain information contained in this Proxy
Statement. This summary is not intended to be complete and is qualified in its
entirety by the more detailed information and financial data appearing elsewhere
in this Proxy Statement and the appendices hereto. Shareholders are urged to
review carefully the entire Proxy Statement and the appendices hereto.

Universal Hospital Services, Inc.

     UHS is a Minnesota corporation with its principal offices at 1250 Northland
Plaza, 3800 West 80th Street, Bloomington, Minnesota 55431-4442. UHS provides
movable medical equipment to hospitals and other healthcare providers through
equipment management programs utilizing Pay-Per-Use/TM/ as the system for
charging customers only for actual equipment usage.

MEDIQ Incorporated; PRN Merger Corporation

     MEDIQ is a Delaware corporation. Its principal executive offices are
located at One MEDIQ Plaza, Pennsauken, New Jersey 08110-1460. MEDIQ, through
its wholly-owned subsidiary, MEDIQ/PRN Life Support Services, Inc., operates the
largest moveable critical care and life support medical equipment rental
business in the United States. MEDIQ is a public company whose stock is traded
on the American Stock Exchange under the symbol "MED."

     PRN Merger Corporation ("Merger Sub") was organized under the laws of the
state of Minnesota on February 6, 1997 as a wholly-owned indirect subsidiary of
MEDIQ for the purposes of entering into the Merger Agreement and effecting the
Merger. Merger Sub has conducted no business. Its principal executive offices
are located at One MEDIQ Plaza, Pennsauken, New Jersey 08110-1460.

Matters to be Considered at the Special Meeting; Vote Required

     At the Special Meeting, shareholders will be asked to consider and vote on
a proposal to approve the Merger Agreement, a copy of which is attached as
Appendix A to this Proxy Statement and is incorporated herein by reference.
Approval of the Merger Agreement requires the affirmative vote of the holders of
a majority of the outstanding shares of UHS Common Stock. See "THE SPECIAL
MEETING-Matters to be Considered at the Meeting" and "-Voting Information."

The Special Meeting; Record Date; Quorum

     The Special Meeting of Shareholders of UHS will be held on April 4, 1997,
9:00 a.m., Central Time, at the Radisson Hotel South, 7800 Normandale
Boulevard, Bloomington, Minnesota. Only holders of record of UHS Stock at the
close of business on February 26, 1997 (the "Record Date") are entitled to
notice of, and to vote at, the Special Meeting. On that date, there were
5,372,421 shares of UHS Common Stock outstanding, with each share entitled to
cast one vote. The presence (in person or by proxy) of the holders of a majority
of the outstanding shares of UHS Common Stock is necessary to constitute a
quorum at the Special Meeting. Abstentions and broker nonvotes are counted for
purposes of determining whether a quorum exists at the Special Meeting. However,
abstentions, broker nonvotes and proxies that are not returned will have the
same effect as a "no" vote with respect to the Merger because approval by the
holders of a majority of the outstanding shares is required to appr ove the
Merger Agreement. See "THE SPECIAL MEETING-Voting Information."

Structure of the Merger

     Pursuant to the Merger Agreement, Merger Sub will merge with and into UHS,
with UHS being the surviving corporation after the Merger (the "Surviving
Corporation"). Each outstanding share of UHS Common Stock, together with the
associated Rights (other than (i) shares as to which dissenters rights are
perfected and (ii) any shares owned directly or indirectly by MEDIQ) will be
converted into the right to receive the Merger Consideration, without interest.
Each outstanding share of common stock of Merger Sub will be exchanged for one
share of the stock of the Surviving Corporation. See "THE MERGER AGREEMENT-
General," "-Consideration to be Received by Shareholders" and "-Payment for
Shares."

Recommendation of the Special Committee and the Board of Directors

     The Special Committee of the UHS Board of Directors (the "Special
Committee"), as well as the full Board of Directors of UHS, each has unanimously
determined, based upon factors it deemed relevant, that the terms of the Merger
Agreement are fair to, and in the best interests of, UHS and its shareholders,
and each has unanimously approved and adopted the Merger Agreement and
unanimously recommends that the UHS shareholders vote FOR the proposal to
approve and adopt the Merger Agreement. See "THE MERGER-Background of the
Merger" and "-Reasons for the Merger and Recommendation of the Special Committee
and Board of Directors."

     Piper Jaffray, Inc. ("Piper Jaffray"), an investment banking firm, has
rendered a written opinion to the Special Committee to the effect that as of the
effective date of such opinion, and subject to the assumptions, factors and
limitations set forth therein, the Merger Consideration is fair to the UHS
shareholders from a financial point of view. The full text of the written
opinion of Piper Jaffray, which sets forth the assumptions made, procedures
followed, matters considered and limits of review, is attached as Appendix B to
this Proxy Statement. SHAREHOLDERS ARE URGED TO AND SHOULD READ THE OPINION OF
PIPER JAFFRAY CAREFULLY. See "THE MERGER-Opinion of UHS Financial Advisor."

Reasons of UHS for the Merger

     The decision of the Special Committee and the Board of Directors to approve
and recommend the Merger Agreement was the product of the Special Committee's
lengthy evaluation process described under "THE MERGER-Background of the
Merger." This process involved (a) consideration of the alternatives available
to the Company; (b) the implementation of a controlled auction process
coordinated by Piper Jaffray to generate the highest, bona fide acquisition
proposals for the Company and review of such proposals by the Special Committee
with the assistance of its financial and legal advisors; and (c) numerous
meetings of the Special Committee at which the Special Committee considered
various acquisition proposals and strategic alternatives with the advice and
assistance of its outside financial and legal advisors.

     In determining to approve and recommend the Merger Agreement, the Special
Committee considered a number of factors, including the following: (a) the fact
that the Merger Consideration represents a substantial premium over trading
prices for the UHS Common Stock during the months preceding the announcement of
the Merger; (b) the Special Committee's review of strategic alternatives to
enhance shareholder value and the Special Committee's belief that the Merger
presents the best opportunity to achieve such objective; (c) the unlikelihood
that any other bidder would emerge to make a superior offer; (d) information
with respect to the financial condition, results of operations, business and
prospects of the Company; (e) the terms and conditions of the Merger Agreement,
which terms and conditions the Special Committee believed increased the
likelihood that the Merger would be

                                       2

consummated; (f) the presentations of Piper Jaffray at numerous meetings of the
Special Committee and the opinion of Piper Jaffray as of February 10, 1997 that
the Merger Consideration is fair, from a financial point of view, to the
Company's shareholders; and (g) that the Merger Agreement permits the Company to
terminate the Merger Agreement in response to an unsolicited Superior Proposal
(as defined herein) provided that UHS pays a $3,000,000 Break-Up Fee (as defined
in the Merger Agreement). See "THE MERGER-Reasons for the Merger and
Recommendation of the Special Committee and Board of Directors."

Reasons of MEDIQ and Merger Sub for the Merger

     MEDIQ has determined that the Merger is in its best interests because it
expects to be able to take advantage of the synergies and economies of scale
that are expected to result from combining and consolidating the field
operations of MEDIQ and UHS, together with the savings that are expected to
result from the elimination of duplicate administrative expenses. In addition,
MEDIQ expects to be able to reduce capital expenditures through the
consolidation of the equipment rental pools of MEDIQ and UHS. Finally, MEDIQ
expects the combination of MEDIQ and UHS to result in an expansion of MEDIQ's
customer base.

Certain Effects of the Merger

     As a result of the Merger, UHS will become a wholly-owned indirect
subsidiary of MEDIQ, and the current shareholders of UHS will no longer have any
continuing interest in UHS. As of the Effective Time, UHS Common Stock will no
longer be traded on the Nasdaq Stock Market, and the registration of UHS Common
Stock under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
will be terminated.

     After the Merger, UHS's Board of Directors will be composed of individuals
designated by MEDIQ, and the officers of Merger Sub at the effective time of the
Merger (the "Effective Time") will be the initial officers of UHS after the
Merger until their respective successors are duly appointed or elected and
qualified.

     Upon consummation of the Merger, the maturity date of certain UHS
indebtedness will be accelerated. See "CERTAIN EFFECTS OF THE MERGER."

Conduct of Business if the Merger is Not Consummated

     If the Merger does not occur, UHS will continue its current operations.
However, for the reasons discussed under the caption "THE MERGER-Background of
the Merger," UHS may continue to explore strategic alternatives, including a
business combination or sale of UHS.

     If the Merger is not consummated, MEDIQ may, with the consent of UHS,
purchase UHS Common Stock from time to time subject to availability at prices
deemed acceptable to MEDIQ, pursuant to a merger transaction, tender offer, open
market or privately negotiated transactions or otherwise on terms more or less
favorable to UHS shareholders than the terms of the Merger. However, MEDIQ has
made no determination as to any future transactions if the Merger is not
consummated. See "THE MERGER-Conduct of Business if the Merger is Not
Consummated."

Interests of Certain Persons in the Merger

     In considering the recommendation of the Special Committee of the Board of
Directors of UHS with respect to the Merger Agreement, the shareholders of UHS
should be aware that certain members of UHS's management and Board of Directors
have interests in the Merger that are different from, or in addition to, the
interests of UHS shareholders generally, including, but not limited to, rights
to severance payments in the event of employment termination under certain
circumstances. See "INTERESTS OF CERTAIN PERSONS IN THE MERGER."

The Support/Voting Agreements

     MEDIQ has entered into Support/Voting Agreements with certain members of
UHS management, specifically, Thomas A. Minner, Paul W. Larsen, Michael W.
Bohman, and Duane R. Wenell (collectively, the "Supporting Stockholders"),
pursuant to which they have agreed to vote all of their shares in favor of the
Merger. As of the Record Date, the Supporting Stockholders beneficially owned in
the aggregate 858,907 shares of UHS Common Stock, or approximately 16.0% of the
shares outstanding as of the Record Date. See "THE SPECIAL MEETING-Voting
Information."

Dissenters' Rights

     Under the Minnesota Business Corporation Act (the "MBCA"), any holder of
UHS Common Stock who does not vote in favor of the Merger and who strictly
complies with the procedural requirements of Section 302A.473 of the MBCA, the
full text of which is included in Appendix C to this Proxy Statement, will have
the right to dissent to the Merger Agreement and make written demand for the
payment of "fair value" of such holder's shares of UHS Common Stock. See "RIGHTS
OF DISSENTING SHAREHOLDERS."

Certain Federal Income Tax Consequences of the Merger

     The receipt of cash for UHS Common Stock in the Merger will be a taxable
transaction for federal income tax purposes under the Internal Revenue Code of
1986, as amended, and also may be a taxable transaction under applicable state,
local, foreign and other tax laws. See "CERTAIN FEDERAL INCOME TAX
CONSEQUENCES."

Effective Time of the Merger

     The Merger will become effective upon the filing of Articles of Merger with
the Secretary of State of the State of Minnesota. The filing will occur promptly
after all conditions to the Merger contained in the Merger Agreement have been
satisfied or waived, which UHS and MEDIQ currently contemplate will occur on or
about April 4, 1997. See "THE MERGER AGREEMENT-General" and "-Effective
Time."

Conditions to Consummation of the Merger

     The Merger is subject to various closing conditions, including the
expiration of the applicable waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), and the
requisite approval of UHS shareholders. See "THE MERGER AGREEMENT-Conditions to
Consummation of the Merger."

Termination of the Merger Agreement

     The Merger Agreement may, under specified circumstances, be terminated and
the Merger abandoned at any time prior to filing Articles of Merger with the
Minnesota Secretary of State, notwithstanding approval of the Merger Agreement
by the shareholders of UHS.

     The Merger Agreement may be terminated by UHS upon approval by the UHS
Board of Directors of a Superior Proposal (as defined in the Merger Agreement)
and payment by UHS to MEDIQ of the $3,000,000 Break-Up Fee. In addition, UHS is
required to pay the $3,000,000 Break-Up Fee to MEDIQ upon termination of the
Merger Agreement by MEDIQ if the UHS Board of Directors or the Special Committee
(i) has withdrawn, modified or changed its recommendation regarding the approval
of the Merger Agreement or the Merger in a manner adverse to MEDIQ; (ii) has
recommended to the UHS shareholders any Acquisition Proposal (as defined in the
Merger Agreement); (iii) has taken any action under the Rights Agreement (as
defined herein) to exclude any person or entity (other than MEDIQ, Merger Sub or
their affiliates) from the definition of "Acquiring Person" (as defined in the
Rights Agreement) or to redeem the Rights; (iv) has taken any action under
Section 302A.673 of the MBCA to approve any "business combination" (as defined
in the MBCA) with an "interested shareholder" (as defined in the MBCA) (other
than MEDIQ, Merger Sub or their affiliates) prior to such shareholder's "share
acquisition date" (as defined in the MBCA) or the acquisition of shares by such
shareholder; (v) has taken any action to provide that an Acquisition Proposal
(as defined herein) shall be exempt from the provisions of Section 302A.671 of
the MBCA; or (vi) has resolved to do any of the foregoing.

     UHS is also obligated to pay the $3,000,000 Break-Up Fee to MEDIQ if (i)
the Merger Agreement is terminated because of a failure to receive the requisite
shareholder approval of the Merger and, prior to the Special Meeting, UHS had
entered into discussions or negotiations with any other person or entity with
respect to an Acquisition Proposal and the Board of Directors of UHS had not
reaffirmed its Merger recommendation to the UHS shareholders by the time of the
Special Meeting or (ii) the Merger Agreement is terminated because of a wilful
breach by UHS of its obligations under the Merger Agreement and within twelve
months after such termination, a merger, consolidation or other business
combination involving UHS or an acquisition of 50% or more of an equity interest
in UHS is consummated with any other person or entity. See "THE MERGER
AGREEMENT-Termination."

Regulatory Approvals

     Under the HSR Act, the Merger may not be consummated unless notice has been
given and certain information has been furnished to the Antitrust Division of
the United States Department of Justice and the Federal Trade Commission. UHS
and MEDIQ submitted the filings required under the HSR Act on or before March 
11, 1997 and such filings are currently pending. See "REGULATORY APPROVALS."

Market Price for UHS Common Stock

     On February 10, 1997, the last full trading day prior to the public
announcement of the Merger Agreement, the high and low sales prices reported for
shares of UHS Common Stock on the Nasdaq Stock Market were $12.50 and $12.00,
respectively, and the closing price was $12.38. On March 18, 1997, the closing
price for shares of UHS Common Stock, as reported on the Nasdaq Stock Market,
was $17.125. See "MARKET PRICE AND DIVIDEND INFORMATION FOR UHS COMMON STOCK."

     SHAREHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR THEIR SHARES
OF UHS COMMON STOCK.

Payment Agent; Surrender of Stock Certificates

     Norwest Bank Minnesota, N.A. (161 North Concord Exchange, South St. Paul,
Minnesota 55075 ((612) 450-4064) will act as the payment agent (the "Payment
Agent") for the Merger. Promptly after the Effective Time, but in no event later
than five business days thereafter, the Payment Agent will send to each UHS
shareholder (other than those shareholders holding shares as to which
dissenters' rights have been perfected) a letter of transmittal advising as to
the procedures for surrendering certificates representing shares of UHS Common
Stock in exchange for the Merger Consideration. Certificates should not be
surrendered until the letter of transmittal is received. As soon as practicable
following receipt from the shareholder of a duly executed letter of transmittal,
together with certificates formerly representing UHS Common Stock and any other
items specified by the letter of transmittal, the Payment Agent will pay the
Merger Consideration to such shareholder, by check or draft less any amount
required to be withheld under applicable federal income tax regulations. See
"THE MERGER AGREEMENT-Payment for Shares."

Accounting Treatment

     MEDIQ will account for the Merger under the "purchase" method of
accounting, in accordance with generally accepted accounting principles.

(1)  As a result of refinancing and early retirement of debt, UHS wrote off
     $153,760 (net of tax benefit of $108,000) of deferred debt placement costs
     during 1992.

(2)  Earnings per share of UHS Common Stock is calculated by dividing net
     income, less redeemable preferred stock dividends and the increase in the
     redeemable preferred stock redemption premium, by the weighted average of
     common and common equivalent shares outstanding during the year. Common
     equivalent shares include the dilutive effect of stock options. The
     increases in the redeemable preferred stock redemption premium and the
     amount of redeemable preferred stock dividends were $193,094 and $1,063,270
     for the years ended December 31, 1992 and 1991, respectively. The
     redeemable preferred stock was retired during 1992.

(3)  No UHS Common Stock cash dividends have been declared or paid by UHS.


                              THE SPECIAL MEETING

Introduction

   This Proxy Statement is being furnished to the shareholders of UHS in
connection with the solicitation of proxies by the Board of Directors of UHS for
use at the Special Meeting to be held on April 4, 1997 at 9:00 a.m., Central
Time, at the Radisson Hotel South, 7800 Normandale Boulevard, Bloomington,
Minnesota, and at any adjournments or postponements thereof.

Matters to be Considered at the Meeting

   At the Special Meeting, the shareholders of UHS will be asked to consider and
vote on a proposal to approve the Merger Agreement, as well as any other matters
that may properly come before the Special Meeting and any postponements or
adjournments thereof.  In addition to approval of the Merger Agreement,
shareholders may be asked to approve a proposal to adjourn the Special Meeting
to permit further solicitation of proxies if there are not sufficient
affirmative votes at the time of the Special Meeting to approve the Merger
Agreement.  A proxy voting against the proposal to approve the Merger Agreement
will not be voted to approve a proposal to adjourn the Special Meeting. It is
not anticipated that any other matters will be brought before the Special
Meeting.  However, if other matters should properly come before the Special
Meeting, it is intended that the holders of proxies solicited hereby will vote
thereon in their discretion, unless such authority is withheld.

Voting Information

   Holders of record of UHS Common Stock at the close of business on February
26, 1997 are entitled to vote at the Special Meeting.  On that date, 5,372,421
shares of UHS Common Stock were outstanding and held by approximately 1,200
shareholders.  Each outstanding share of UHS Common Stock is entitled to one
vote.  The presence, in person or by proxy, of the holders of a majority of the
outstanding shares of UHS Common Stock entitled to vote at the Special Meeting
is necessary to constitute a quorum for the transaction of business at such
meeting.  Abstentions and broker nonvotes are counted for purposes of
determining whether a quorum exists at the Special Meeting.  However, proxies
that reflect abstentions and broker nonvotes and proxies that are not returned
will have the same effect as a "no" vote with respect to the Merger because the
affirmative vote of the holders of a majority of the outstanding shares of UHS
Common Stock is required to approve the Merger Agreement.

   As of February 26, 1997, 5,372,421 shares of UHS Common Stock were
outstanding.  Accordingly, the affirmative vote of at least 2,686,211 shares of
UHS Common Stock is a condition to the consummation of the Merger.  Certain
members of the management of UHS (the "Supporting Shareholders") owning in the
aggregate 858,907 shares of UHS Common Stock have agreed, pursuant to

                                       8
<PAGE>
 
Support/Voting Agreements dated as of February 17, 1997 between MEDIQ and each
such management person, to vote such shares of UHS Common Stock in favor of the
Merger and the Merger Agreement. See "THE MERGER-Background of the Merger."

Solicitation, Revocation and Use of Proxies

     UHS will pay the costs of soliciting proxies from its shareholders and the
costs of reporting and mailing this Proxy Statement, the enclosed proxy and any
other material furnished to its shareholders in connection with the Special
Meeting. In addition to the solicitation of proxies by mail, certain UHS
directors, officers and employees may solicit proxies by telephone, telecopy and
personal contact, without separate compensation for such activities. Copies of
solicitation materials will be furnished to fiduciaries, custodians and
brokerage houses for forwarding to beneficial owners of UHS Common Stock, and
such persons will be reimbursed for their reasonable out-of-pocket expenses
incurred in connection therewith.  The Company has also retained Morrow & Co., 
Inc. to solicit proxies, by mail, in person or by telephone, at an estimated 
cost of $5,000 plus reimbursement of reasonable out-of-pocket expenses.

     Any person giving a proxy in the form accompanying this Proxy Statement has
the power to revoke it at any time before it is exercised. The proxy may be
revoked by filing with the Secretary of UHS an instrument of revocation or a
duly executed proxy bearing a later date. Such filing must be made to the
attention of the Secretary of UHS by mailing or delivering such filing to the
principal executive offices of UHS located at 1250 Northland Plaza, 3800 West
80th Street, Bloomington, Minnesota 55431-4442, Attention: Secretary. The proxy
may also be revoked by affirmatively electing to vote in person while attending
the meeting. However, a shareholder who attends the meeting need not revoke his
or her proxy and vote in person unless he or she wishes to do so. All valid
proxies will be voted at the meeting in accordance with the instructions given.
If no instructions are given, the shares represented by the proxy will be voted
at the Special Meeting FOR approval of the Merger Agreement and in accordance
with this Proxy Statement on any other business that may properly come before
the Special Meeting and any postponements or adjournments thereof.


                                  THE MERGER

     At a special meeting held on February 10, 1997, the Special Committee
unanimously determined that the Merger is fair to, and in the best interests of,
the shareholders of UHS, approved the Merger Agreement and the transactions
contemplated thereby, and determined to recommend to the UHS shareholders that
they vote for approval and adoption of the Merger Agreement. Thereafter, at a
special meeting of the full Board of Directors of UHS, the Board unanimously
ratified the actions of the Special Committee and approved the Merger Agreement
and such transactions. Following these meetings, on February 10, 1997, UHS,
MEDIQ and Merger Sub entered into the Merger Agreement. The following discussion
sets forth certain information relating to the background of the discussions and
meetings leading up to the Merger.

Background of the Merger

     Since the Company's initial public offering in 1992, the Board of Directors
and management of the Company have evaluated and considered various alternatives
for enhancing shareholder value. Over the last few years the Board of Directors
has generally believed that the trading prices of the UHS Common Stock have not
reflected the potential value of the Company. The Company believes that the
market price for the UHS Common Stock has been adversely affected by several
factors. First, the number of shares of UHS Common Stock in the public float has
historically been relatively limited. Second, the average daily trading volume
of the UHS Common Stock, which is traded on the Nasdaq Stock Market, has been
low historically, restricting the level of interest in the UHS Common Stock.
Third, since the initial public offering in 1992, the Company has had a very
limited number of market makers and investment banking firms preparing research
reports with respect to the Company. Fourth, the Company believes that its
medical equipment rental business does not fit squarely within any

                                       9
<PAGE>
 
particular investment sector (i.e., either the healthcare or financial services
segment) and that there are very few comparable public companies engaged in
similar businesses in relation to which investors may assess the Company's
performance. Fifth, the Company experienced a number of earnings disappointments
over the last several years due to the effect on the Company's business of
customer uncertainty over healthcare reform and the resulting deferral by those
customers of medical equipment procurement decisions.

     In recent years, UHS has initiated or explored a number of efforts aimed at
enhancing shareholder value, such as strategic partnerships with medical
equipment manufacturers, acquisitions and, more recently, measures aimed at
improving operating margins, such as salary and work force reductions and
deferral of new office openings. To date, the Company does not believe that
these efforts have had any significant positive effect on improving share price.
In addition, although the secondary offering in late 1995 by a selling
shareholder of shares representing approximately 30% of the outstanding UHS
Common Stock increased the public float of the UHS Common Stock, the UHS Common
Stock has remained thinly traded.

     As a result of these factors and the actions of certain of the Company's
investors described below, the Company intensified its efforts to explore
strategic alternatives to enhance shareholder value during the second half of
1996. During this period, a number of the Company's significant shareholders
expressed their concerns that the then current market prices for UHS Common
Stock did not reflect the intrinsic value of the Company and indicated their
belief that the Company should take immediate steps to enhance shareholder
value. On October 7, 1996, Peter H. Kamin and Peak Investment Limited
Partnership (together, "Peak") filed a Schedule 13D reporting that Peak had
acquired shares of UHS Common Stock representing 7.8% of the Company's reported
outstanding UHS Common Stock, that Peak intended to review its investment and
that Peak may propose one or more actions to enhance shareholder value or to
effect a change of control of the Company. During September 1996, members of the
Company's management met with representatives of Piper Jaffray to discuss ways
to enhance shareholder value.

     At the October 29, 1996 regular meeting of the Board of Directors the
concerns of the Company's investors were discussed. Based upon preliminary
discussions between members of the Company's management and representatives of
Piper Jaffray in September 1996, the Company asked Piper Jaffray to make a
presentation to its full Board of Directors. At the October 29, 1996 meeting,
the Board met with Piper Jaffray to discuss in general terms ways to enhance
shareholder value and the possible engagement of Piper Jaffray to assist in the
Company's efforts. In addition, representatives of each of Piper Jaffray and
outside counsel to the Company presented certain information to the Company
regarding the potential benefits of adopting a shareholder rights plan in order
to provide the Board of Directors the opportunity to adequately review the
Company's strategic alternatives. At the October 29, 1996 Board meeting the
directors determined to schedule a November 8, 1996 meeting to further discuss
the benefits of adopting a shareholder rights plan.

     On October 30, 1996, Private Capital Management (together with its
affiliates, "PCM"), a significant shareholder of UHS which had previously
reported in a Schedule 13G that it had acquired shares of UHS Common Stock for
investment purposes, filed a Schedule 13D stating that it believed that the then
current market price of UHS Common Stock did not reflect the intrinsic value of
the Company, that the Company should consider taking proactive steps to enhance
shareholder value (including, among other things, a possible business
combination with a strategic or financial buyer), and that PCM intended to
review its investment in the Company on a continuing basis and may consider
taking such actions as it believed would facilitate the enhancement of
shareholder value.

     On October 31, 1996, Thomas A. Minner, the Company's Chief Executive
Officer, received a telephone call from Thomas E. Carroll, President of MEDIQ
indicating MEDIQ's interest in acquiring the Company. On that occasion, Mr.
Minner indicated to Mr. Carroll that the Company was not currently for sale, but
that he would inform the Company's Board of Directors of MEDIQ's interest.

                                      10
<PAGE>
 
     On November 5, 1996, the Company received a letter from MEDIQ indicating
MEDIQ's interest in acquiring the Company for an unspecified consideration "in
the range of" $10.50 per share.

     On November 7, 1996, the Company engaged Piper Jaffray to assist the
Company in analyzing its strategic alternatives and to assist the Board of
Directors in evaluating, and potentially implementing, a shareholder rights
plan. Karen M. Bohn, a director of UHS, is a Managing Director and Chief
Administrative Officer of Piper Jaffray Companies, Inc., the parent of Piper
Jaffray. See "INTERESTS OF CERTAIN PERSONS IN THE MERGER-Certain Relationships."

     On November 8, 1996, the Board of Directors of UHS met with Piper Jaffray
and the Company's outside counsel to discuss the process of exploring
alternatives to enhance shareholder value and the merits of implementing a
shareholder rights plan during such a process. Representatives of Piper Jaffray
and outside counsel to the Company made presentations regarding shareholder
rights plans generally and the proposed form of rights agreement to be adopted
by the Company. At that meeting, after a thorough discussion and analysis, the
Board of Directors approved the Rights Agreement dated as of November 8, 1996
(the "Rights Agreement") between the Company and Norwest Bank Minnesota, N.A.,
as rights agent. Under the Rights Agreement, rights to purchase shares of Series
A Junior Participating Preferred Stock of UHS (the "Rights") were distributed as
a dividend to shareholders of record of UHS Common Stock as of the close of
business on November 21, 1996. For a description of the terms of the Rights see
"DESCRIPTION OF UHS CAPITAL STOCK-Rights" below.

     At the November 8, 1996 Board meeting, the Board also authorized Piper
Jaffray to initiate a process of exploring its strategic alternatives, including
the possible sale of the Company or continuing to operate the Company as an
independent entity, and to contact potential buyers. On November 11, 1996, the
Company issued a press release announcing the initiation of this process, the
engagement of Piper Jaffray, the receipt of the letter referred to above from
MEDIQ (without naming MEDIQ or the price range set forth in the letter), and the
Company's adoption of the Rights Agreement.

     Thereafter, the Company and Piper Jaffray received calls from the
representatives of various entities interested in an acquisition of the Company.
During the course of the next several weeks, Piper Jaffray also initiated
contact with a number of potential acquirors of the Company, some of whom had
informally expressed a possible interest in such a transaction prior to November
1996. Over the course of its engagement, Piper Jaffray contacted a total of 30
potentially interested parties representing both strategic and financial buyers
for purposes of soliciting proposals for potential acquisitions, mergers or
other strategic alliances. Piper Jaffray and the Company prepared a confidential
information memorandum and distributed the memorandum to 23 interested parties,
each of whom each signed a confidentiality agreement.

     On November 22, 1996, representatives of Smith Barney Inc., on behalf of
MEDIQ, met with representatives of Piper Jaffray to discuss the process
announced by the Company and to express again the strong interest of MEDIQ in
acquiring the Company. No price or other specific terms of a transaction were
discussed.

     At a December 9, 1996 special meeting of the Board of Directors, the Board
established a special committee (the "Special Committee") comprised of the
Company's non-employee directors to carry out the process of exploring
alternatives to enhance shareholder value and to make a recommendation to the
full Board of Directors. On December 12, 1996, the Company announced the
establishment of the Special Committee.

     In response to a request from Piper Jaffray for preliminary proposals, on
or prior to December 13, 1996 the Company received eight preliminary indications
of interest. Of the eight indications of interest, five expressed interest in a
purchase of the Company, one proposed a strategic alliance between the Company
and a major medical products company, one proposed the sale to UHS of a


                                      11
<PAGE>
 
subsidiary of another company and one proposed financing a self-tender by the
Company for a portion of its shares which would be accompanied by a change in
management of the Company. All of the five acquisition proposals (including a
proposal from MEDIQ) involved a cash acquisition of all of the UHS Common Stock
with cash consideration to the Company's shareholders in the range of $11.50 to
$14.00 per share. David E. Dovenberg, the Company's Chief Financial Officer, was
participating in two of the acquisition proposals.

     On December 18, 1996, the Special Committee held a meeting to review each
of these indications of interest as well as the other strategic alternatives
that were being evaluated. At this meeting, the Special Committee's legal
advisors and Piper Jaffray reviewed the process by which the proposals had been
solicited and the terms of each of the proposals received. Piper Jaffray also
analyzed other strategic alternatives available to the Company such as pursuing
a strategy of growth through acquisitions, the declaration of a special dividend
and the self-tender proposal. Based on this review, the Special Committee
determined that each of the five acquisition proposals should be given further
consideration by the Company. In addition, the Special Committee requested that
Piper Jaffray, together with certain members of the Company's management,
continue to assist the Special Committee in further assessing the strategic
alliance proposal. Based on the presentations and analysis of its financial and
legal advisors, the Special Committee determined that it would not then pursue
further the self-tender proposal, the proposed acquisition by the Company of the
subsidiary of another company, the strategy of pursuing growth through
acquisitions generally or the declaration of a special dividend. On December 19,
1996, the Company issued a press release announcing that it had received at
least four preliminary indications of interest from qualified parties and a
preliminary indication of interest from a major healthcare company concerning a
possible a strategic alliance.

     Over the next six weeks, Piper Jaffray and senior management of the Company
met with representatives of the five potential acquirors referred to above
(including MEDIQ) and engaged in a telephone conference with representatives of
the healthcare company that submitted the strategic alliance proposal. Piper
Jaffray and the Company's senior management assisted these potential acquirors
in their conduct of a due diligence review of the Company.

     On or before January 27, 1997, four of the five potential acquirors of the
Company (including MEDIQ) submitted revised proposals to acquire the Company,
including their changes to a form of acquisition agreement supplied by the
Company. All four of the second round proposals involved a cash acquisition
(through tender offer or merger) of all of the UHS Common Stock. Two of the
proposals involved a price per share of $14.00 and two of the proposals involved
a price per share of $15.00.

     On January 30, 1997, the Special Committee held a meeting to review each of
these four proposals as well as the strategic alliance alternative. At this
meeting, the Special Committee's legal advisors and Piper Jaffray reviewed the
process by which the proposals had been solicited and the terms of each of the
proposals received. Piper Jaffray again provided the Special Committee with its
valuation analysis of the Company as an independent publicly-traded company,
which analysis had not materially changed from its presentations at prior
meetings. (For a discussion of the valuation analysis of Piper Jaffray, see "THE
MERGER-Opinion of UHS Financial Advisor" below.) The Special Committee concluded
that each of the four second round proposals compared favorably to Piper
Jaffray's valuation analysis. In addition, the Special Committee, together with
its legal and financial advisors, reviewed the strategic alliance proposal, an
analysis of the impact such an alliance would have on the financial performance
of the Company, the time such an alliance would take to be implemented and the
uncertainty regarding the future potential of such an alliance. Based on these
factors, the Special Committee concluded that the second round acquisition
proposals appeared to present a greater opportunity to enhance shareholder
value.

     After evaluating the alternatives for enhancing shareholder value, in
consultation with its legal and financial advisors, the Special Committee
determined to recommend to the Board of Directors of the Company that the
Company pursue a sale of the Company on terms acceptable to the


                                      12
<PAGE>
 
Company and its shareholders. Immediately following the meeting of the Special
Committee, on January 30, 1997, the Board of Directors met and reviewed this
recommendation of the Special Committee. The full Board of Directors unanimously
ratified and approved the recommendation of the Special Committee and further
authorized the Special Committee to proceed with the negotiation and approval of
a sale of the Company on terms approved by the Special Committee.

     Thereafter, three of the four bidders modified their proposals. On February
5, 1997, the Special Committee met and, together with its financial and legal
advisors, reviewed the three third round proposals, which proposals all
continued to involve a cash acquisition of all of the UHS Common Stock with a
per share price in the range of $14.50 to $17.50. Based on this review, the
Special Committee concluded that the proposal from MEDIQ (which offered a
transaction priced at $17.50 per share of UHS Common Stock) provided price and
other terms sufficiently more favorable to the Company and its shareholders than
any other proposal. The Special Committee authorized its financial advisors and
legal counsel (including legal counsel to the Company) to negotiate a sale of
the Company to MEDIQ on substantially the terms outlined in MEDIQ's third round
bid.

     Following the February 5, 1997 meeting of the Special Committee,
representatives of the Company and of MEDIQ continued their discussions and
negotiations regarding the terms of the Merger Agreement. These further
discussions and negotiations continued throughout the period from February 5 to
February 10, 1997. The Merger Agreement in substantially its definitive form was
discussed with members of the Special Committee at a telephonic meeting on
February 9, 1997. The definitive Merger Agreement was approved by both the
Special Committee and the Board of Directors of the Company at a special meeting
held on February 10, 1997, and was signed by the Company and MEDIQ on
February 10, 1997.

Reasons for the Merger and Recommendation of the Special Committee and Board of
Directors

     The Special Committee, at a special meeting held on February 10, 1997,
unanimously approved the Merger Agreement and the transactions contemplated
thereby, including the Merger. The Board of Directors, at a special meeting held
immediately thereafter, ratified the actions of the Special Committee and also
unanimously approved the Merger Agreement and the transactions contemplated
thereby, including the Merger. The Special Committee and the Board of Directors
have determined that the Merger Agreement is in the best interest of the
shareholders of the Company and recommend that the Company's shareholders vote
FOR the authorization and adoption of the Merger Agreement.

     The decision of the Special Committee and the full Board to approve and
recommend the Merger Agreement was the product of the Special Committee's
lengthy evaluation process described under "THE MERGER-Background of the
Merger." This process involved (a) consideration of the alternatives available
to the Company, namely (i) a sale of the Company, (ii) pursuing other strategic
alternatives such as a strategic alliance with a major healthcare company,
pursuing a strategy of growth through acquisitions, engaging in a self-tender or
declaring a special dividend, and (iii) the maintenance of the operations of the
Company as an independent public company; (b) the implementation of a controlled
auction process coordinated by Piper Jaffray to generate the highest, bona fide
acquisition proposals for the Company and review of such proposals by the
Special Committee with the assistance of its legal and financial advisors; and
(c) numerous meetings of the Special Committee held from mid-December through
early February, at which the Special Committee considered the various
acquisition proposals and strategic alternatives with the advice and assistance
of its outside financial and legal advisors.

     In determining to approve and recommend the Merger Agreement, the Special
Committee considered a number of factors, including the following:


                                      13
<PAGE>
 
          (a)  the fact that the Merger Consideration of $17.50 per share
     represents a premium of approximately 125.8% over the $7.75 closing price
     per share on November 8, 1996 (the trading day prior to the announcement by
     the Company that it had retained Piper Jaffray as financial advisor to
     assist the Board in evaluating strategic alternatives, including the
     possible sale of the Company) and a premium of approximately 41.4% over the
     closing sales price of $12.38 per share for the UHS Common Stock as
     reported on the Nasdaq Stock Market on February 10, 1997 (the last full
     trading day prior to the announcement of the execution of the Merger
     Agreement);

          (b)  the Special Committee's review of the potential strategic
     alternatives to enhance shareholder value and the Special Committee's
     belief that the Merger presents the best opportunity to achieve such
     objective (see "THE MERGER-Background of the Merger");

          (c)  that the Company had publicly announced that it was potentially
     for sale, that the execution of the Merger Agreement followed a controlled
     auction process and, in light of the process that had been followed, the
     unlikelihood that any other bidder would emerge to make a superior offer;

          (d)  information with respect to the financial condition, results of
     operations, business and prospects of the Company, including the prospects
     of the Company if it were to remain independent, and current industry,
     economic and market conditions;

          (e)  the terms and conditions of the Merger Agreement, including that
     the Merger Agreement does not include a financing condition to the
     obligations of MEDIQ and Merger Sub to consummate the Merger, which terms
     and conditions the Special Committee believed increased the likelihood that
     the Merger would be consummated;

          (f)  the presentations of Piper Jaffray at numerous meetings of the
     Special Committee and the opinion as of February 10, 1997 of Piper Jaffray
     that the Merger Consideration is fair, from a financial point of view, to
     the Company's shareholders (see "THE MERGER-Background of the Merger" and
     "--Opinion of UHS Financial Advisor"); and

          (g)  that the Merger Agreement permits the Company to terminate the
     Merger Agreement or take certain other actions in response to an
     unsolicited Acquisition Proposal if the Board, in the exercise of its
     fiduciary obligations (as determined in good faith by the Board based on
     the advice of its outside counsel), determines that such Acquisition
     Proposal is a Superior Proposal and pays the $3,000,000 Break-Up Fee (see
     "THE MERGER AGREEMENT-Restriction on Solicitation" and "-Termination").

     In view of the wide variety of factors considered in connection with its
evaluation of the terms of the Merger, the Company's Board of Directors did not
find it practicable to, and did not, quantify or otherwise attempt to assign
relative weights to the specific factors considered in reaching its conclusions.

     The Special Committee evaluated the factors described above in light of
their knowledge of the business and operations of the Company, and their
business judgment, and concluded that the $17.50 per share in cash as Merger
Consideration was in the best interests of the Company and its shareholders.

Opinion of UHS Financial Advisor

     Pursuant to engagement letters dated November 7 and 13, 1996, the Board of
Directors of UHS retained Piper Jaffray to review and analyze a variety of
strategic alternatives available to UHS to enhance shareholder value. On
December 12, 1996, the UHS Board of Directors announced the formation and
appointment of the Special Committee to consider UHS's strategic alternatives.
Pursuant to an engagement letter dated January 3, 1997 (the "Engagement
Letter"), the Special

                                      14
<PAGE>
 
Committee retained Piper Jaffray to act as financial advisor to the Special
Committee and, if requested, to render an opinion as to the fairness, from a
financial point of view, to UHS shareholders of the consideration to be received
by such shareholders in any proposed transaction.

     At a meeting of the Special Committee on January 30, 1997, Piper Jaffray
made a presentation summarizing the process by which proposals to acquire UHS
had been solicited, summarizing and comparing the four second-round proposals to
acquire UHS and analyzing the proposals (in a manner similar to that summarized
below) and summarizing and analyzing the proposal concerning a strategic
alliance. At a meeting of the Special Committee on February 10, 1997, Piper
Jaffray delivered its written opinion to the Special Committee to the effect
that, as of such date, and subject to the assumptions, factors and limitations
set forth therein, the consideration to be received by the UHS shareholders
pursuant to the Merger Agreement is fair, from a financial point of view, to the
UHS shareholders. On March 18, 1997, in connection with the mailing of the Proxy
Statement, Piper Jaffray reaffirmed its opinion as of such date. A copy of Piper
Jaffray's written opinion dated March 18, 1997, which sets forth the assumptions
made, matters considered and limits on the review taken, is attached as Appendix
B to this Proxy Statement and is incorporated herein by reference (the "Piper
Jaffray Opinion"). The February 10, 1997 opinion of Piper Jaffray is
substantially identical to the Piper Jaffray Opinion attached as Appendix B. UHS
shareholders are urged to read the Piper Jaffray Opinion in its entirety. The
description of the Piper Jaffray Opinion set forth herein is qualified in its
entirety by reference to the full text of such opinion. The Piper Jaffray
Opinion is directed only to the financial terms of the Merger Agreement and does
not constitute a recommendation to any UHS shareholder as to how such
shareholder should vote at the UHS Special Meeting.

     In arriving at its opinion, Piper Jaffray reviewed and analyzed, among
other things, (i) the Merger Agreement; (ii) certain publicly available
information concerning UHS; (iii) certain financial forecasts and projections
prepared by UHS's management; (iv) the historical stock prices and trading
volumes of UHS Common Stock; (v) publicly available financial data of publicly
held companies which it deemed generally comparable to UHS; and (vi) the
financial terms of certain other recent business combinations, which it deemed
generally relevant. In addition, Piper Jaffray held discussions with members of
the management of UHS concerning the financial condition, current operating
results and business outlook for UHS and the background and rationale of the
proposed Merger. Piper Jaffray visited UHS's headquarters and Minneapolis
district office, and performed such other studies, analyses, inquiries and
investigations as it deemed appropriate.

     In connection with its review, Piper Jaffray relied upon and assumed the
accuracy and completeness of the financial and other information provided to it
by UHS or otherwise made available to Piper Jaffray, and did not attempt
independently to verify such information. Piper Jaffray assumed, in reliance
upon the assurances of the management of UHS, that the information provided to
Piper Jaffray by UHS was prepared on a reasonable basis in accordance with
industry practice and, with respect to financial planning data, reflected the
best currently available estimates and judgments of UHS's management as to the
expected future financial performance of UHS, and that the management of UHS was
not aware of any information or facts that would make the information provided
to Piper Jaffray incomplete or misleading. Piper Jaffray also assumed that there
were no material changes in UHS's assets, financial condition, results of
operations, business or prospects since the date of the last financial
statements made available to Piper Jaffray. In addition, Piper Jaffray did not
assume responsibility for performing any appraisals or valuations of specific
assets or liabilities of UHS and was not furnished with any such appraisals or
valuations. Further, the Piper Jaffray Opinion was based on economic, monetary
and market conditions existing on, and the information made available to Piper
Jaffray as of, March 18, 1997.

     Set forth below is a summary of selected analyses Piper Jaffray relied upon
in rendering its opinion:

MEDIQ common stock and the Standard & Poor's 500 Composite Index and Nasdaq
Composite Index.

     Comparable Transaction Analysis

     Piper Jaffray reviewed and analyzed certain financial data from a group of
five selected mergers and acquisitions in the medical equipment rental business
completed between June 1987 and September 1996 and deemed comparable to the
Merger.  For these transactions, Piper Jaffray analyzed the ratio of target
company value (market capitalization plus debt less cash) to target latest
twelve months ("LTM") sales; target company value to LTM earnings before
interest, taxes, depreciation and amortization ("EBITDA"); and target equity
value (market capitalization) to LTM net income.  For these transactions, this
analysis showed that the ratio of target company value to target LTM sales
ranged from 1.3 to 2.3, with a mean of 1.6 and median of 1.4, compared with a
multiple of 2.3 for UHS based on the Merger Consideration; the ratio of target
company value to LTM EBITDA ranged from 4.1 to 7.2, with a mean of 5.0 and a
median of 4.8, compared with a multiple of 6.3 for UHS based on the Merger
Consideration; and the ratio of target equity value to LTM net income ranged
from 13.5 to 26.5, with a mean of 19.2 and a median of 17.6, compared with a
multiple of 46.0 for UHS based on the Merger Consideration.  All LTM numbers for
UHS were pro forma numbers as of September 30, 1996 adjusted to reflect the
acquisition by UHS of Biomedical Equipment Rentals & Sales, Inc. ("BERS") as if
it had occurred on October 1, 1995 and adding back an inventory write down of
$1.03 million.

     Premiums Paid Analysis

     Piper Jaffray also reviewed and analyzed the premiums paid in recent
acquisitions of a group of publicly held companies.  The analysis examined the
difference between the proposed acquisition offer price and the target's price
per share at various times prior to the announcement of a possible transaction.
In selecting comparable transactions for the premiums paid analysis, Piper
Jaffray only included cash transactions in which 100% of the target's shares
were acquired, transactions with a value between $35 million and $300 million,
and transactions completed between January 1, 1996 and January 27, 1997.  This
analysis revealed 32 completed transactions that Piper Jaffray deemed to be
comparable.  For these transactions, the implied premiums paid, based on the
target share price four 

                                       16

weeks prior to the announcement of a possible transaction compared with the
proposed acquisition offer price, ranged from (-17.5%) to 148.3%, with a mean of
39.1% and a median of 31.8%, compared with a premium of 150.0% for this
transaction; based on the target share price one week prior to announcement
compared with the proposed acquisition offer price, ranged from (-30.5%) to
125.0%, with a mean of 35.2% and a median of 27.2%, compared with a premium of
129.5% for this transaction; and based on the target share price one day prior
to announcement compared with the proposed acquisition offer price, ranged from
(-26.7%) to 132.3%, with a mean of 26.1% and a median of 22.4%, compared with a
premium of 125.8% for this transaction. For purposes of its analysis, Piper
Jaffray assumed an announcement date for this transaction of November 11, 1996.
On that date, UHS announced that it had received an acquisition proposal from
another company, that it had hired Piper Jaffray to explore strategic
alternatives and that it was implementing a shareholder rights plan.

     Discounted Cash Flow Analysis

     Using a discounted cash flow analysis, Piper Jaffray calculated a range of
theoretical per share values for UHS, based on the net present value of implied
future cash flows of UHS and a terminal value assuming UHS is sold in 2001 at a
multiple of EBITDA.  Piper Jaffray used internal financial planning data
prepared by management of UHS for 1997 through 2001 that reflect UHS as a
standalone entity.  From 1993, the first full year after the initial public
offering, through 1996, UHS's cash flow grew at a compounded annual rate of
2.73%.  From 1997 through 2001, the projected years used in the discounted cash
flow analysis, UHS's implied future cash flow was projected by management in its
internal planning data to grow at a compounded annual rate of 33.7%.   Piper
Jaffray calculated the range of net present values for UHS based on a range of
discount rates of 15% to 19% and a range of terminal value multiples of
forecasted 2001 EBITDA of 4.0x to 6.0x.  This analysis yielded a range of
estimated present values for UHS of between $8.33 per share and $17.70 per
share.

     Comparable Company Analysis

     Piper Jaffray compared selected financial data and ratios for UHS to the
corresponding data and ratios for two groups of companies deemed comparable to
UHS, all of which are publicly traded companies whose primary business is small
equipment rental, with the first comparable group of two companies healthcare
related, and the second group of eight companies non-healthcare related.  The
financial data and ratios compared as part of this analysis included the stock
price as a percentage of the 52-week high; the multiple of company value to LTM
EBITDA; the multiple of market price to LTM earnings per share; the multiple of
market price to estimated 1996 earnings per share; the multiple of market price
to estimated 1997 earnings per share; EBITDA margin (LTM); EBIT margin (LTM);
net margin (LTM); and three-year historical revenue growth.

     This analysis showed that this group of equipment rental companies had a
stock price as a percentage of the 52-week high ranging from 75.6% to 98.2% for
healthcare related companies (72.9% to 99.5% for non-healthcare related
companies), with a mean of 86.9% and a median of 86.9% for healthcare related
companies (88.7% and 90.2%, respectively, for non-healthcare related companies);
a multiple of company value to LTM EBITDA ranging from 4.9 to 6.6 for healthcare
related companies (2.8 to 11.0 for non-healthcare related companies), with a
mean of 5.8 and a median of 5.8 for healthcare related companies (5.5 and 5.3,
respectively, for non-healthcare related companies); a multiple of market price
to LTM earnings per share ranging from 18.9 to 19.6 for healthcare related
companies (12.0 to 25.6 for non-healthcare related companies), with a mean of
19.2 and a median of 19.2 for healthcare related companies (17.2 and 15.9,
respectively, for non-healthcare related companies); a multiple of market price
to estimated 1996 earnings per share ranging from 17.3 to 19.6 for healthcare
related companies (12.1 to 26.6 for non-healthcare related companies), with a
mean of 18.4 and a median of 18.4 for healthcare related companies (18.3 and
16.8, respectively, for non-healthcare related companies); a multiple of market
price to estimated 1997 earnings per share ranging from 13.8 to 18.3 for
healthcare related companies (9.7 to 22.2 for non-healthcare related companies),
with a mean of 16.0 and a median of 16.0 for healthcare related companies (15.5
and 15.2, respectively, for 

                                       17
<PAGE>
 
non-healthcare related companies); EBITDA margin (LTM) ranging from 8.7% to 
42.5% for healthcare related companies (21.5% to 90.9% for non-healthcare
related companies), with a mean of 25.6% and a median of 25.6% for healthcare
related companies (51.5% and 54.8%, respectively, for non-healthcare related
companies); EBIT margin (LTM) ranging from 5.2% to 20.3% for healthcare related
companies (11.6% to 33.8% for non-healthcare related companies), with a mean of
12.8% and a median of 12.8% for healthcare related companies (22.5% and 22.0%,
respectively, for non-healthcare related companies); net margin (LTM) ranging
from 1.7% to 6.8% for healthcare related companies (4.7% to 18.5% for non-
healthcare related companies), with a mean of 4.3% and a median of 4.3% for
healthcare related companies (9.5% and 7.3%, respectively, for non-healthcare
related companies); and three-year historical revenue growth ranging from 6.8%
to 29.2% for healthcare related companies (1.9% to 33.4% for non-healthcare
related companies), with a mean of 18.0% and a median of 18.0% for healthcare
related companies (14.7% and 12.1%, respectively, for non-healthcare related
companies).

     By comparison, Piper Jaffray determined that the transaction price
represented by the Merger Consideration yielded a stock price as a percentage of
the 52-week high of 167%; a ratio of company value to LTM EBITDA of 6.3 for UHS;
a multiple of market price to LTM earnings per share for UHS of 46.0; a multiple
of market price to estimated 1996 earnings per share for UHS of 39.8; a multiple
of market price to estimated 1997 earnings per share for UHS of 27.8; EBITDA
margin (LTM) for UHS of 36.3%; EBIT margin (LTM) for UHS was 11.4%; net margin
(LTM) for UHS of 3.6%; and three-year historical revenue growth for UHS of 7.2%.
All LTM numbers for UHS were pro forma numbers as of September 30, 1996 adjusted
to reflect the acquisition of BERS as if it had occurred on October 1, 1995 and
adding back an inventory write down of $1.03 million.

     Although the summary set forth above does not purport to be a complete
description of the analyses performed by Piper Jaffray, the material analyses
performed by Piper Jaffray in rendering its opinion have been summarized above.
The preparation of a fairness opinion is not, however, necessarily susceptible
to partial analysis or summary description.  Piper Jaffray believes that its
analyses and the summary set forth above must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, or
selecting part or all of the above summary, without considering all factors and
analyses, would create an incomplete view of the processes underlying the
analyses set forth in the Piper Jaffray Opinion.  In addition, Piper Jaffray may
have given various analyses more or less weight than other analyses but no
analysis was given materially more weight than any other analysis.  The fact
that any specific analysis has been referred to in the summary above is not
meant to indicate that such analysis was given greater weight than any other
analysis.

     In performing its analyses, Piper Jaffray made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of UHS.  The analyses
performed by Piper Jaffray are not necessarily indicative of actual values or
actual future results, which may be significantly more or less favorable than
suggested by such analyses.  Such analyses were prepared solely as part of Piper
Jaffray's analysis of the fairness of the consideration to be paid in connection
with the Merger to UHS shareholders.  The analyses do not purport to be
appraisals or to reflect the prices at which a company might actually be sold or
the prices at which any securities may trade at the present time or at any time
in the future.  In addition, as described above, the Piper Jaffray Opinion was
one of many factors taken into consideration by the Special Committee in making
its determination to approve the Merger Agreement.

     Piper Jaffray was selected by UHS on the basis of its experience in valuing
securities in connection with mergers and acquisitions and its knowledge of UHS.
Piper Jaffray is a nationally recognized investment banking firm and is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, underwritings and secondary
distributions of securities, private placements and valuations for estate,
corporate and other purposes.  Piper Jaffray was initially retained to act as
financial advisor to the Board of Directors, and since January 3, 1997 has acted
as financial advisor to the Special Committee.  Although Piper Jaffray assisted
the Special Committee in certain of the negotiations leading to the Merger
Agreement, Piper Jaffray was not asked to, and did 

                                       18
<PAGE>
 
not, propose the specific Merger Consideration. The Merger Consideration was
determined by arms-length negotiations between UHS and MEDIQ after consultation
by each of the parties with their respective financial advisors as to various
matters, including preliminary ranges of value.

     Piper Jaffray has from time to time issued research reports and
recommendations on the UHS Common Stock and, in the ordinary course of business,
has acted as a market maker in UHS Common Stock. Karen M. Bohn, a Managing
Director and the Chief Administrative Officer of Piper Jaffray Companies, Inc.,
the parent of Piper Jaffray Inc., is a director of UHS and a member of the
Special Committee.

     Pursuant to the Engagement Letter, for acting as financial advisor to the
Special Committee, UHS has agreed to pay Piper Jaffray (i) a fee of $125,000 due
under the initial engagement letter dated November 7, 1996; (ii) $275,000 in
cash upon Piper Jaffray rendering an opinion to the Special Committee as to the
fairness, from a financial point of view, of the consideration to be received by
UHS shareholders in connection with a transaction such as the Merger; (iii)
$25,000 in cash upon Piper Jaffray rendering an updated opinion at the time of
mailing of this Proxy Statement to the UHS shareholders; and (iv) in the event a
sale or merger of UHS, including the Merger, is consummated pursuant to an
agreement or commitment which is entered into before January 3, 2000, a success
fee payable in cash equal to 1.8% of the consideration paid in such transaction
for the equity of UHS, including options, less the fees paid under (i), (ii) and
(iii) above. To date, Piper Jaffray has been paid an aggregate of $425,000 of
fees pursuant to the Engagement Letter. Whether or not the Merger is
consummated, UHS has also agreed to reimburse Piper Jaffray for its reasonable
out-of-pocket expenses and to indemnify it against certain liabilities relating
to or arising out of services performed by Piper Jaffray as financial advisor to
UHS.


                             THE MERGER AGREEMENT

     The description of the Merger Agreement contained in this Proxy Statement
does not purport to be complete and is qualified in its entirety by, and made
subject to, the more complete information set forth in the Merger Agreement, a
copy of which is attached as Appendix A to this Proxy Statement and incorporated
herein by reference.

General

     UHS, MEDIQ and Merger Sub entered into the Merger Agreement as of
February 10, 1997. If the shareholders of UHS approve the Merger Agreement,
Merger Sub will be merged with and into UHS, and the separate corporate
existence of Merger Sub will then cease. UHS will be the Surviving Corporation
and will become an indirect wholly-owned subsidiary of MEDIQ. At the Effective
Time, the UHS Common Stock will be converted automatically into the right to
receive the Merger Consideration, as described below. See "THE MERGER AGREEMENT-
Payment for Shares" and " -Payment of Stock Options and Rights." The shares of
UHS Common Stock will no longer be listed or traded on the Nasdaq Stock Market,
and the registration of the UHS Common Stock under the Exchange Act will be
terminated.

Effective Time

      If the Merger Agreement is adopted by the requisite vote of UHS
shareholders, the Merger will be consummated and become effective upon the
filing of articles of merger with the Secretary of State of the State of
Minnesota. It is currently contemplated that the Effective Time will occur on or
about April 4, 1997, subject to satisfaction of all conditions to the Merger, 
including receipt of all required regulatory approvals as of such date. There
can be no assurance that all conditions to the Merger will be satisfied. See
"THE MERGER AGREEMENT-Conditions to Consummation of the Merger."

                                      19

Consideration to be Received by Shareholders

     In connection with the Merger, each share of UHS Common Stock outstanding
immediately prior to the Effective Time (other than (i) dissenting shares and
(ii) any shares owned directly or indirectly by MEDIQ), together with the
associated Rights, will be converted into the right to receive $17.50 in cash,
without interest (the cash consideration to be paid to UHS's shareholders in the
Merger being sometimes referred to herein as the "Merger Consideration").
Dissenting shares will be converted to cash in the manner described under the
caption "RIGHTS OF DISSENTING SHAREHOLDERS."

Payment for Shares

     Norwest Bank Minnesota, N.A. (the "Payment Agent") will act as the agent
for payment of the Merger Consideration to the holders of UHS Common Stock.
Instructions with regard to the surrender of certificates formerly representing
shares of UHS Common Stock, together with the letter of transmittal to be used
for that purpose, will be mailed to shareholders as soon as practicable after
the Effective Time, but in no event later than five business days thereafter. As
soon as practicable following receipt from the shareholder of a duly executed
letter of transmittal, together with certificates formerly representing UHS
Common Stock and any other items specified by the letter of transmittal, the
Payment Agent will pay the Merger Consideration to such shareholder, by check or
draft less any amount required to be withheld under applicable federal income
tax regulations.

     After the Effective Time, the holder of a certificate formerly representing
UHS Common Stock will cease to have any rights as a shareholder of UHS, and such
holder's sole right will be to receive the Merger Consideration with respect to
such shares (or, in the case of dissenting shares, the statutorily determined
"fair value"). If payment is to be made to a person other than the person in
whose name the surrendered certificate is registered, it will be a condition of
payment that the certificates so surrendered be properly endorsed or otherwise
be in proper form for transfer and that the person requesting such payment pays
any transfer or other taxes required by reason of such payment or establishes to
the satisfaction of the Payment Agent that such taxes have been paid or are not
applicable. No transfer of shares of UHS Common Stock outstanding immediately
prior to the Effective Time will be made on the stock transfer books of the
Surviving Corporation after the Effective Time. Other than as described above,
no service charges, brokerage commissions or transfer taxes will be payable by
UHS shareholders in connection with the surrender of their shares of UHS Common
Stock.

     To the extent permitted by law, the appointment of the Payment Agent will
be terminated after 12 months following the Effective Time. Any portion of the
Merger Consideration remaining undistributed upon termination of the Payment
Agent's appointment will be returned to the Surviving Corporation, and any
holders of theretofore unsurrendered UHS Common Stock certificates may
thereafter surrender to the Surviving Corporation such stock certificates and
(subject to abandoned property, escheat or similar laws) receive in exchange
therefor the Merger Consideration to which they are entitled.

     In no event will holders of shares of UHS Common Stock be entitled to
receive payment of any interest on the Merger Consideration.

     SHAREHOLDERS OF UHS SHOULD NOT FORWARD THEIR STOCK CERTIFICATES TO THE
PAYMENT AGENT WITHOUT A LETTER OF TRANSMITTAL, AND SHOULD NOT RETURN THEIR STOCK
CERTIFICATES WITH THE ENCLOSED PROXY.

Payment of Stock Options and Rights

     Upon the consummation of the Merger, each option to acquire shares of UHS
Common Stock outstanding immediately prior to the Effective Time under UHS's
1992 Long-Term Incentive and Stock Option Plan, as amended (the "ISO Plan"), and
UHS's 1992 Directors' Stock Option Plan, as amended (the "Directors' Plan"),
whether vested or unvested (each, an "Option," and collectively, the "Options")
will automatically become immediately vested and exercisable and each holder of
an Option will have the right to receive from MEDIQ a cash payment (less
applicable withholding taxes) in an aggregate amount equal to the difference
between the Merger Consideration and the exercise price per share applicable to
such Option for all shares subject to the Option as expressly stated in the
applicable stock option agreement or other agreement (the "Option
Consideration"). Under the Merger Agreement, UHS has agreed to take such actions
as are necessary to fully advise holders of Options of their rights under the
Merger Agreement and the Options. After the Effective Time, no holder of an
Option shall have any rights other than to receive payment for such holder's
Options equal to the Option Consideration. See "INTERESTS OF CERTAIN PERSONS IN
THE MERGER-UHS Stock Options."

     Under the Merger Agreement, any outstanding purchase rights under UHS's
1992 Employee Stock Purchase Plan, as amended (the "ESPP"), will be exercised
upon the earlier of the next scheduled purchase date under the ESPP or
immediately before the Effective Time. If immediately before the Effective Time
any purchase right is still outstanding, such rights will be exercised
immediately. At that time, each participant in the ESPP will be issued shares
which shall be canceled at the Effective Time and converted into the right to
receive the Merger Consideration. The ESPP shall terminate with such exercise
date, and no purchase rights shall be subsequently granted or exercised under
the ESPP. See "INTERESTS OF CERTAIN PERSONS IN THE MERGER-Employee Stock
Purchase Plan."

past practice and that, in the aggregate, do not result in a material increase
in such employee's benefits or compensation relative to the level in effect
prior to such amendment); (c) pay any benefit not provided under any existing
plan or arrangement; (d) grant any awards under any bonus, incentive,
performance or other compensation plan or arrangement or employee benefit plan
(including, without limitation, the grant of stock options, stock appreciation
rights, stock based or stock related awards, performance units or restricted
stock, or the removal of existing restrictions in any benefit plans or
agreements or awards made thereunder) (other than such plans and arrangements
which are made in the ordinary course of business consistent with past
practice); (e) take any action to fund or in any other way secure the payment of
compensation or benefits under any employee plan, agreement, contract or
arrangement or employee benefit plan other than in the ordinary course of
business consistent with past practice; or (f) adopt, enter into, amend or
terminate any contract, agreement, commitment or arrangement to do any of the
foregoing.

Restriction on Solicitation

     UHS has agreed that, prior to the Effective Time it will not, and will
cause the Subsidiary not to, and will use its best efforts to cause the
officers, directors, employees, representatives and agents of UHS and the
Subsidiary not to, directly or indirectly, solicit, initiate or encourage any
inquiry, proposal, offer or indication of interest from any person that
constitutes or would reasonably be expected to lead to any Acquisition Proposal,
or enter into discussions or negotiate with any person or entity in furtherance
of any such inquiries or to obtain or approve any Acquisition Proposal, or agree
to or endorse any Acquisition Proposal. As agreed, UHS will immediately notify
MEDIQ of all relevant terms of any such inquiries or proposals received by UHS
or the Subsidiary or by any such officer, director, employee, representatives or
agents, relating to any of such matters, any material change in the details
(including any amendments or proposed amendments) of any such inquiries or
proposals, the identity of each of the persons or entities making such inquiries
or proposals, and, if such inquiry or proposal is in writing, UHS will
immediately deliver or cause to be delivered to MEDIQ a copy of such inquiry or
proposal. However, if, prior to the Effective Time, UHS receives an unsolicited
Acquisition Proposal that the Board of Directors of UHS, based upon the advice
of its legal counsel, reasonably believes that it has a fiduciary duty to
consider, then UHS, without violating the Merger Agreement, may thereafter
furnish information to and enter into discussions or negotiations with such
third party. Nothing contained in the Merger Agreement prevents the Special
Committee or the Board of Directors of UHS, after receiving an opinion of
outside counsel to the effect that the Board of Directors is required to do so
in order to discharge properly its fiduciary duties, from considering,
negotiating, approving and recommending to the UHS shareholders an unsolicited,
bona fide written Acquisition Proposal which the Board of Directors of UHS
determines in good faith (after consultation with its financial advisors) (A)
would result in a transaction more favorable to UHS shareholders than the
transaction contemplated by the Merger Agreement and (B) is made by a person
financially capable of consummating such Acquisition Proposal (such an
Acquisition Proposal is referred to in the Merger Agreement as a "Superior
Proposal"). If the Board of Directors resolves to accept or accepts a Superior
Proposal, then upon written notice to MEDIQ, UHS may terminate the Merger
Agreement, provided that UHS must pay MEDIQ the $3,000,000 Break-Up Fee. An
"Acquisition Proposal" is defined in the Merger Agreement as any proposal for a
merger, consolidation or other business combination involving UHS or the
acquisition of any equity interest in, or a substantial portion of the assets of
UHS or the Subsidiary, other than the transactions contemplated by the Merger
Agreement.

Conditions to Consummation of the Merger

     The Merger will occur only if the Merger Agreement is approved and adopted
by the requisite votes of the holders of the UHS Common Stock. Consummation of
the Merger also is subject to the satisfaction of certain other conditions
specified in the Merger Agreement, unless such conditions are waived (to the
extent such waiver is permitted by law). The failure of any such condition to be
satisfied, if not waived, would prevent consummation of the Merger.

     The obligations of MEDIQ to consummate the Merger are subject to
satisfaction of, among others, the following conditions: (a) (i) UHS shall have
performed and complied in all material respects with all of its covenants and
agreements under the Merger Agreement to be performed or complied with prior to
or before the Effective Time; and (ii) each of the representations and
warranties of UHS contained in the Merger Agreement shall have been true and
correct as of the date of execution of the Merger Agreement and as of the
Effective Time in all material respects (except for any representation or
warranty which is qualified by materiality, which must be true and correct in
all respects); (b) MEDIQ shall have received certificates from a duly authorized
officer of UHS (in such person's capacity as an officer without personal
liability) certifying as to the fulfillment of the conditions set for in (a)
above; (c) the Merger Agreement and the Merger shall have received the necessary
approval of UHS shareholders; (d) the applicable waiting period under the HSR
Act shall have expired or terminated; (e) no preliminary or permanent injunction
or other order by any federal or state court in the United States which prevents
the consummation of the Merger shall have been issued and remain in effect; and


                                       24
<PAGE>
 
(f) the Rights shall not have become nonredeemable, exercisable, distributed
or triggered pursuant to the terms of the Rights Agreement.

     The obligations of UHS to consummate the Merger are subject to satisfaction
of the following conditions, among others:  (a) (i) MEDIQ shall have performed
and complied in all material respects with all of its covenants and agreements
under the Merger Agreement to be performed or complied with prior to or before
the Effective Time; and (ii) each of the representations and warranties of MEDIQ
contained in the Merger Agreement shall have been true and correct as of the
date of execution of the Merger Agreement and as of the Effective Time in all
material respects (except for any representation or warranty which is qualified
by materiality, which must be true and correct in all respects); (b) UHS shall
have received certificates from a duly authorized officer (in such person's
capacity as an officer without personal liability) of MEDIQ and Merger Sub
certifying as to the fulfillment of the conditions set forth in (a) above; (c)
the Merger Agreement and the Merger shall have received the necessary approval
of UHS shareholders; (d) the applicable waiting period under the HSR Act shall
have expired or terminated; and (e) no preliminary or permanent injunction or
other order by any federal or state court in the United States which prevents
the consummation of the Merger shall have been issued and remain in effect.

Employment Matters

     The parties to the Merger Agreement have agreed to certain post-closing
covenants regarding employees of UHS and the Subsidiary (the "UHS Employees").
MEDIQ has agreed that the UHS Employees will continue employment with the
Surviving Corporation and its subsidiary, respectively, in the same positions
and at the same level of wages and/or salary and without having incurred a
termination of employment or separation from service; provided, however, except
as may be specifically required by applicable law or any contract, the Surviving
Corporation and its subsidiaries are not obligated to continue any employment
relationship with any UHS Employee for any period of time. MEDIQ, Merger Sub and
UHS have agreed that UHS Employees whose employment is terminated on or after
the Effective Time or within 12 months thereafter will receive severance
payments to the extent provided pursuant to a policy agreed to by UHS and MEDIQ.
MEDIQ agrees that UHS Employees who remain employed by the Surviving Corporation
following the Merger will be eligible to participate in all plans, programs or
policies then afforded to similarly situated employees of MEDIQ and its
affiliated companies.

Indemnification of Officers and Directors

     Under the Merger Agreement, the Surviving Corporation will until the later
of (i) the six year anniversary date of the Effective Time or (ii) the
respective termination or expiration date of any indemnification agreement or
arrangement of UHS or the Subsidiary, cause its articles of incorporation and
bylaws to continue to provide indemnification provisions for the benefit of
those individuals who have served as directors or officers of UHS or the
Subsidiary at any time prior to the Effective Time. Such provision will be
comparable to the provisions as are currently contained in UHS's or the
Subsidiary's articles of incorporation and bylaws. In addition, subject to the
occurrence of the Effective Time, MEDIQ has guaranteed unconditionally full
payment and performance of the indemnification obligations discussed above.
MEDIQ has also agreed, subject to certain limitations, to use reasonable efforts
to cause the Surviving Corporation to maintain for the benefit of such persons
for a period of six years after the Merger, officers' and directors' liability
insurance comparable in scope and amount to the officers' and directors'
insurance coverage currently maintained by UHS. See "INTERESTS OF CERTAIN
PERSONS IN THE MERGER-Indemnification of Officers and Directors."

Termination

     The Merger Agreement may be terminated and the Merger abandoned at any time
prior to the filing of articles of merger with the Minnesota Secretary of State,
whether before of after action by UHS shareholders, and without further approval
by UHS shareholders, under any of the following circumstances:

          (a)  by mutual written consent of the Board of Directors of each of
     MEDIQ and UHS;

          (b)  by either MEDIQ or UHS, if any of the conditions to such party's
     obligation to consummate the transactions contemplated in the Merger
     Agreement shall have become impossible to satisfy;

          (c)  by either MEDIQ or UHS, if the Merger has not been consummated on
     or before August 30, 1997 (unless the failure to consummate the Merger by
     such date shall be due to the action or failure to act of the party seeking
     to terminate the Merger Agreement in breach of such party's obligations
     under the Merger Agreement);

          (d)  by UHS upon approval of a Superior Proposal and payment of the
     Break-Up Fee; or
     
          (e)  By MEDIQ, if the Board of Directors of UHS or the Special
     Committee (i) withdraws, modifies or changes its recommendation regarding
     the approval of the Merger Agreement or the Merger in a manner adverse to
     MEDIQ; (ii) shall have recommended to the UHS shareholders any Acquisition
     Proposal; (iii) shall have taken any action under the Rights Agreement to
     exclude any person or entity (other than MEDIQ, Merger Sub or their
     affiliates) from the definition of "Acquiring Person" (as defined in the
     Rights Agreement) or to redeem the Rights; (iv) shall have taken any action
     under Section 302A.673 of the MBCA to approve any "business combination"
     (as defined in the MBCA) with an "interested shareholder" (as defined in
     the MBCA) (other than MEDIQ, Merger Sub or their affiliates) prior to such
     shareholder's "share acquisition date" (as defined in the MBCA) or the
     acquisition of shares by such shareholder; (v) shall have taken any action
     to provide that an Acquisition Proposal shall be exempt from the provisions
     of Section 302A.671 of the MBCA; or (vi) shall have resolved to do any of
     the foregoing.

     UHS shall be obligated to pay a $3,000,000 Break-Up Fee to MEDIQ if (i) UHS
or MEDIQ terminates the Merger Agreement pursuant to clauses (d) or (e) above,
(ii) the Merger Agreement is terminated because of a failure to receive the
requisite shareholder approval of the Merger and, prior to the Special Meeting,
UHS had entered into discussions or negotiations with any person or entity with
respect to an Acquisition Proposal and the Board of Directors of UHS had not
reaffirmed its Merger recommendation to the UHS shareholders by the time of the
Special Meeting or (iii) the Merger Agreement is terminated because of a breach
by UHS and within twelve months after such termination, a merger, consolidation
or other business combination involving UHS or an acquisition of 50% or more of
an equity interest in UHS is consummated with any other person or entity.

Expenses

     Under the Merger Agreement, generally all costs and expenses incurred by
UHS, MEDIQ and Merger Sub will be paid by the party that has incurred such costs
and expenses. However, if the Merger Agreement is terminated for certain reasons
specified in the Merger Agreement, UHS is required to pay MEDIQ the $3,000,000
Break-Up Fee. See "THE MERGER AGREEMENT-Restrictions on Solicitation" and
"-Termination."

                                       26
<PAGE>
 
                         CERTAIN EFFECTS OF THE MERGER

     As a result of the Merger, UHS will become a wholly-owned indirect
subsidiary or MEDIQ and the current shareholders of UHS will not have any
continuing interest in UHS. UHS Common Stock will no longer be traded on the
Nasdaq Stock Market, and the registration of UHS Common Stock under the Exchange
Act will be terminated.

     After the Merger, UHS's Board of Directors will be composed of individuals
designated by MEDIQ, and the officers of Merger Sub at the effective time of the
Merger (the "Effective Time") will be the initial officers of UHS after the
Merger until their respective successors are duly appointed or elected and
qualified.

     The Rights are not currently exercisable and, pursuant to the Merger
Agreement, UHS has taken all action necessary (i) to render the Rights
inapplicable to the Merger and the transactions contemplated by the Merger
Agreement and (ii) to ensure that a "Distribution Date" (as defined in the
Rights Agreement) will not occur by reason of the announcement or consummation
of the Merger or any of the other transactions contemplated by the Merger
Agreement. The Rights will expire at the Effective Time and thereafter the
shareholders of UHS will not have any further rights with respect thereto.

                              REGULATORY APPROVALS

     Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), the Merger may not be consummated until notifications
have been given and certain information has been furnished to the FTC and the
Antitrust Division of the Department of Justice (the "Antitrust Division"), and
specified waiting period requirements have been satisfied. MEDIQ and UHS filed
premerger notification and report forms with the FTC and Antitrust Division on
or before February 18, 1997.

     The waiting period under the HSR Act, which was originally scheduled to
expire on March 20, 1997 (thirty days after the date of filing), will now expire
on April 10, 1997 (thirty days after the date of filing an amendment to the
original filing) unless the period is terminated sooner pursuant to MEDIQ's and
UHS's request for early termination of the waiting period.

     At any time before or after consummation of the Merger, and notwithstanding
the satisfaction of the HSR Act requirements, the FTC or the Antitrust Division
or any state could take action under the federal or state antitrust laws to seek
to enjoin consummation of the Merger. Private parties may also seek to take
legal action under the antitrust laws.

     Based on the information available to them, each of MEDIQ and UHS believes
that the Merger can be effected in compliance with federal and state antitrust
laws. However, there can be no assurance that a challenge to the Merger on
antitrust grounds will not be made or that, if such a challenge were made, MEDIQ
and UHS would prevail.

     Neither UHS nor MEDIQ believes that any material federal or state
regulatory approvals, filings or notices are required in connection with the
Merger other than the filing of articles of merger with the Secretary of State
of the State of Minnesota. Other than as described above, neither UHS nor MEDIQ
is aware of any license or regulatory permit that is material to the business of
UHS and that is likely to be adversely affected by consummation of the Merger or
any approval or other action by any state, federal or foreign government or
governmental agency (other than routine relicensing procedures) that would be
required prior to the Merger.

<PAGE>
 
                             ACCOUNTING TREATMENT

     MEDIQ will account for the Merger under the "purchase" method of accounting
under which the total consideration paid in the Merger will be allocated among
the Surviving Corporation's consolidated assets and liabilities based on the
fair values of the assets acquired and liabilities assumed in the Merger.


                  INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the Special Committee of the Board of
Directors of UHS with respect to the Merger Agreement, the shareholders of UHS
should be aware that certain members of UHS's management and Board of Directors
have interests in the Merger that are different from, or in addition to, the
interests of UHS shareholders generally. The Special Committee of the Board of
Directors of UHS was aware of these interests and considered them in approving
the Merger, the Merger Agreement and the transactions contemplated thereby.

UHS Stock Options

     As described at page 21, above, upon the consummation of the Merger, each
option to acquire shares of UHS Common Stock outstanding immediately prior to
the Effective Time under UHS's 1992 Long-Term Incentive and Stock Option Plan,
as amended (the "ISO Plan") and UHS's 1992 Directors' Stock Option Plan, as
amended (the "Directors' Plan"), whether vested or unvested (each, an "Option,"
and collectively, the "Options"), will automatically become immediately vested
and exercisable and each holder of an Option will have the right to receive from
MEDIQ a cash payment (less applicable withholding taxes) in an aggregate amount
equal to the difference between the Merger Consideration and the exercise price
per share applicable to such Option for all shares subject to the Option as
expressly stated in the applicable stock option agreement or other agreement
(the "Option Consideration"). UHS has agreed to take such other actions
(including, without limitation, giving requisite notices to holders of Options
advising them of such accelerated vesting and rights pursuant to the Merger
Agreement) as are necessary to fully advise holders of Options of their rights
under the Merger Agreement and the Options and to facilitate their timely
exercise of such rights. From and after the Effective Time, other than as
expressly set forth in the Merger Agreement, no holder of an Option will have
any rights in respect thereof other than to receive payment for such holder's
Options equal to the Option Consideration, and the Surviving Corporation shall
take all reasonably necessary actions to terminate UHS's stock option plans and
similar arrangements. The Option Consideration payable upon consummation of the
Merger to executive officers of UHS pursuant to outstanding Options under the
ISO Plan are as follows: Thomas A. Minner, $888,775; Michael W. Bohman,
$490,263; Paul W. Larsen, $490,263; Duane R. Wenell, $490,263; David E.
Dovenberg, $490,263 and all executive officers as a group, $2,849,827. The
Option Consideration payable upon consummation of the Merger to non-employee
directors of UHS, who constituted all of the members of the Special Committee,
pursuant to outstanding Options under the Directors' Plan are as follows: Karen
M. Bohn, $91,000; Samuel B. Humphries, $131,125; Terrance D. McGrath, $131,125;
and all non-employee directors as a group, $353,250.

Employee Stock Purchase Plan

     UHS currently maintains an Employee Stock Purchase Plan (the "ESPP") for
the benefit of certain of its employees. In accordance with the Merger
Agreement, outstanding purchase rights under the ESPP will be exercised upon the
earlier of (i) the next scheduled purchase date under the ESPP or (ii)
immediately prior to the Effective Time, and each participant in the ESPP,
including executive officers of UHS participating therein, accordingly will be
issued shares at that time that shall be cancelled at the Effective Time and
converted into the right to receive the Merger Consideration for those shares.


                                      28
<PAGE>
 
The ESPP shall terminate with such exercise date, and no purchase rights shall
be subsequently granted or exercised under the ESPP.

Change in Control Agreements

     Effective January 1994, UHS adopted the Top Management Change-in-Control
Severance Plan (the "Severance Plan"). The Severance Plan is designed to
encourage continuity of management in the event of a change in control of UHS.
The consummation of the Merger will constitute a "change of control" under the
Severance Plan. Under the Severance Plan, each of UHS's five executive officers
is eligible to receive a severance payment up to three times his base salary in
the event of a change in control of UHS and termination of such officer within
three years of such change in control for reasons other than death, total
disability or "just cause" (as defined in the Severance Plan) and voluntary
termination without "good reason," which is defined in the Severance Plan as an
aggregate reduction of 10% or more in such officer's base salary and benefits, a
material reduction in the nature and scope of such officer's authorities or
duties, or a required relocation of such officer to a location more than 35
miles from such officer's existing job location other than a required relocation
to those locations at which UHS maintained operations prior to the change in
control. The approximate amount payable to each of UHS's executive officers upon
a qualifying termination, assuming current base salaries, is as follows: Mr.
Minner, $845,913; Mr. Bohman, $580,152; Mr. Larsen, $552,912; Mr. Dovenberg,
$531,005 Mr. Wenell, $506,250; and all executive officers and directors as a
group, $3,016,232.

     UHS has certain other compensatory arrangements with its executive officers
which will result from a change in control of UHS. In addition to payment of the
Option Consideration referred to above under the heading "-UHS Stock Options,"
executive officers of UHS are entitled to receive a lump sum payment equal to
the present value of all benefits accrued under the UHS supplemental pension
plan upon any qualifying termination of such executive officer's employment (as
defined under the Severance Plan) within thirty-six months of a change of
control (as defined under the Severance Plan). In the event of such a change in
control and a qualifying termination, executive officers of UHS are also
entitled to payment of a pro rata portion of all awards granted under the UHS
Long-Term Incentive Plan and UHS Annual Incentive Plan based on achievement of
performance objectives during that portion of the performance periods elapsed
prior to the change in control.

Indemnification of Officers and Directors

     The Merger Agreement provides that MEDIQ shall, and shall cause the
Surviving Corporation to, honor the obligations of UHS under Minnesota law and
their respective articles or certificates of incorporation or bylaws relating to
indemnification of the present and former officers, directors, employees or
agents of UHS to full extent permitted thereunder against losses, claims,
damages or liabilities arising out of actions or omissions occurring at or prior
to the Effective Time. MEDIQ has also agreed, subject to certain limitations, to
use reasonable efforts to cause the Surviving Corporation to maintain for the
benefit of such persons for a period of six years after the Merger, officers'
and directors' liability insurance comparable in scope and amount to the
officers' and directors' insurance coverage currently maintained by UHS.

Certain Relationships

     Karen M. Bohn, a director of UHS and a member of the Special Committee, is
a Managing Director and the Chief Administrative Officer of Piper Jaffray
Companies, Inc., the parent of Piper Jaffray. As described above under "THE
MERGER-Opinion of UHS Financial Advisor," Piper Jaffray will receive a fee in
connection with the financial advisory services rendered by Piper Jaffray to the
Company in connection with the Merger and the transactions described under "THE
MERGER-Background of the Merger."

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     Under currently existing provisions of the Internal Revenue Code of 1986,
as amended (the "Code"), the treasury regulations promulgated thereunder,
applicable judicial decisions and administrative rulings, all of which are
subject to change, the federal income tax consequences described below are
expected to arise in connection with the Merger. Due to the complexity of the
Code, the following discussion is limited to the material federal income tax
aspects of the Merger for a UHS shareholder who is a citizen or resident of the
United States and who, as of the Effective Time, holds shares of UHS Common
Stock as a capital asset. The general tax principles discussed below are subject
to retroactive changes that may result from subsequent amendments to the Code.
The following discussion does not address potential foreign, state, local and
other tax consequences, nor does it address taxpayers subject to special
treatment under the federal income tax laws, such as tax-exempt organizations, S
corporations and taxpayers subject to the alternative minimum tax. In addition,
the following discussion may not apply to UHS shareholders who acquired their
shares upon the exercise of employee stock options or otherwise as compensation.
Neither UHS nor MEDIQ has requested either the Internal Revenue Service or
counsel to rule or issue an opinion on the federal income tax consequences of
the Merger. ALL SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
REGARDING THE FEDERAL, FOREIGN, STATE AND LOCAL TAX CONSEQUENCES OF THE
DISPOSITION OF THEIR SHARES IN THE MERGER.

     For federal income tax purposes, the Merger will be treated as a taxable
sale or exchange of shares of UHS Common Stock for cash by each holder of such
shares (including any holder of Dissenting Shares). Accordingly, the federal
income tax consequences to the holders of UHS Common Stock will generally be as
follows:

          (a)  Assuming that the shares of UHS Common Stock exchanged by a UHS
     shareholder for cash in connection with the Merger are capital assets in
     the hands of the shareholder at the Effective Time, such shareholder may
     recognize a capital gain or loss by reason of the consummation of the
     Merger.

          (b)  The capital gain or loss, if any, will be long-term with respect
     to shares of UHS Common Stock held for more than 12 months as of the
     Effective Time and short-term with respect to such shares held for 12
     months or less as of the Effective Time.

          (c)  The amount of capital gain or loss to be recognized by each
     holder of UHS Common Stock will be measured by the difference between the
     amount of cash received by such shareholder in connection with the Merger
     (including cash received for Dissenting Shares) and such shareholder's tax
     basis in the UHS Common Stock at the Effective Time.

     Cash payments made pursuant to the Merger (including any cash paid to
holders of Dissenting Shares) will be reported to the extent required by the
Code to shareholders of UHS and the Internal Revenue Service. Such amounts will
ordinarily not be subject to withholding of federal income tax. However, backup
withholding of such tax at a rate of 31% may apply to certain shareholders by
reason of the events specified in Section 3406 of the Code and the treasury
regulations promulgated thereunder, which include failure of a shareholder to
supply UHS or its agent with such shareholder's taxpayer identification number.
Accordingly, each UHS shareholder will be asked to provide the shareholder's
correct taxpayer identification number on a Substitute Form W-9 which is to be
included in the letter of transmittal to be sent to shareholders relating to
their shares of UHS Common Stock. Withholding may also apply to UHS shareholders
who are otherwise exempt from such withholding, such as a foreign person, if
such person fails to properly document its status as an exempt recipient.

                       RIGHTS OF DISSENTING SHAREHOLDERS

     Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act
(the "MBCA") provide to each shareholder the right to dissent from the Merger,
and obtain payment for the "fair value" of such shareholder's shares following
the consummation of the Merger.

     The following summary of the applicable provisions of Sections 302A.471 and
302A.473 of the MBCA is not intended to be a complete statement of such
provisions and is qualified in its entirety by reference to such sections, the
full texts of which are attached as Appendix C to this Proxy Statement. These
sections should be reviewed carefully by any shareholder who wishes to exercise
dissenters' rights or who wishes to preserve the right to do so, since failure
to comply with the procedures set forth herein or therein will result in the
loss of dissenters' rights.

     Under the MBCA, holders of UHS Common Stock will have the right, by fully
complying with the applicable provisions of Sections 302A.471 and 302A.473, to
dissent with respect to the Merger and to receive from the Surviving Corporation
payment in cash of the "fair value" of their shares of UHS Common Stock after
the Merger is completed. The term "fair value" means the value of the shares of
UHS Common Stock immediately before the Effective Time.

     All references in Sections 302A.471 and 302A.473 and in this summary to a
"shareholder" are to a record holder of the shares of UHS Common Stock as to
which dissenters' rights are asserted. A person having beneficial ownership of
shares of UHS Common Stock that are held of record in the name of another
person, such as a broker, nominee, trustee or custodian, must act promptly to
cause the record holder to follow the steps summarized below properly and in a
timely manner in order to perfect whatever dissenters' rights such beneficial
owner may have.

     Shareholders of record who desire to exercise their dissenters' rights must
satisfy all of the following conditions. A written notice of intent to demand
fair value for shares must be delivered to the executive offices of UHS before
the taking of the shareholder vote on the Merger. This written demand must be in
addition to and separate from any proxy or vote against the Merger. Voting
against, abstaining from voting or failing to vote on the Merger does not
constitute a demand for appraisal within the meaning of the MBCA.

     Shareholders electing to exercise their dissenters' rights under the MBCA
must not vote for adoption of the Merger. A shareholder's failure to vote
against the Merger will not constitute a waiver of dissenters' rights. However,
if a shareholder returns a signed proxy but does not specify a vote against
adoption of the Merger or direction to abstain, the proxy will be voted for
adoption of the Merger, which will have the effect of waiving that shareholder's
dissenters' rights.

     A UHS shareholder may not assert dissenters' rights as to less than all of
the shares registered in such holder's name except where certain shares are
beneficially owned by another person but registered in such holder's name. If a
record owner, such as a broker, nominee, trustee or custodian, wishes to dissent
with respect to shares beneficially owned by another person, such shareholder
must dissent with respect to all of such shares and must disclose the name and
address of the beneficial owner on whose behalf the dissent is made. A
beneficial owner of shares of UHS Common Stock who is not the record owner of
such shares may assert dissenters' rights as to shares held on such person's
behalf, provided that such beneficial owner submits a written consent of the
record owner to UHS at or before time such rights are asserted.

     A shareholder who elects to exercise dissenters' rights must send his or
her written demand, before the taking of the vote on the Merger, to the
Secretary of UHS, 1250 Northland Plaza, 3800 West 80th Street, Bloomington,
Minnesota 55431--4442. The written demand should specify the shareholder's name
and mailing address, the number of shares owned and that the shareholder intends
to demand the value of his or her shares.


                                      31

     After approval of the Merger by the shareholders at the Special Meeting,
the Surviving Corporation will send a written notice to each shareholder who
filed a written demand for dissenters' rights. The notice will contain the
address to which the shareholder shall send a demand for payment and the stock
certificates in order to obtain payment and the date by which they must be
received, a form to be used in connection therewith and other related
information.

     In order to receive fair value for his or her shares, a dissenting
shareholder must, within 30 days after the date such notice was given, send his
or her stock certificates, and all other information specified in the notice
from the Surviving Corporation, to the address specified in such notice. A
dissenting shareholder will retain all rights as a shareholder until the
Effective Time. After a valid demand for payment and the related stock
certificates and other information are received, or after the Effective Time,
whichever is later, the Surviving Corporation will remit to each dissenting
shareholder who has complied with statutory requirements the amount that the
Surviving Corporation estimates to be the fair value of such shareholder's
shares, with interest commencing five days after the Effective Time at a rate
prescribed by statute. Remittance will be accompanied by the Surviving
Corporation's closing balance sheet and statement of income for a fiscal year
ending not more than 16 months before the Effective Time, together with the
latest available interim financial data, an estimate of the fair value of the
shareholder's shares and a brief description of the method used to reach the
estimate, a brief description of the procedure to be followed if such holder is
demanding supplemental payment and copies of Sections 302A.471 and 302A.473 of
the MBCA.

     If the dissenting shareholder believes that the amount remitted by the
Surviving Corporation is less than the fair value of such holder's shares, plus
interest, the shareholder may give written notice to the Surviving Corporation
of such holder's own estimate of the fair value of the shares, plus interest,
within 30 days after the mailing date of the remittance and demand payment of
the difference. Such notice must be given at the executive offices of UHS at the
address set forth above. A shareholder who fails to give such written notice
within this time period is entitled only to the amount remitted by the Surviving
Corporation.

     Within 60 days after receipt of a demand for supplemental payment, the
Surviving Corporation must either pay the shareholder the amount demanded or
agreed to by such shareholder after discussion with the Surviving Corporation or
petition a court for the determination of the fair value of the shares, plus
interest. The petition shall name as parties all shareholders who have demanded
supplemental payment and have not reached an agreement with the Surviving
Corporation. The court, after determining that the shareholder or shareholders
in question have complied with all statutory requirements, may use any valuation
method or combination of methods it deems appropriate to use, whether or not
used by the Surviving Corporation or the dissenting shareholder, and may appoint
appraisers to recommend the amount of the fair value of the shares. The court's
determination will be binding on all UHS shareholders who properly exercised
dissenters' rights and did not agree with the Surviving Corporation as to the
fair value of the shares. Dissenting shareholders are entitled to judgment for
the amount by which the court-determined fair value per share, plus interest,
exceeds the amount per share, plus interest, remitted to the shareholders by the
Surviving Corporation. The shareholders shall not be liable to the Surviving
Corporation for any amounts paid by the Surviving Corporation which exceed the
fair value of the shares as determined by the court, plus interest. The costs
and expenses of such a proceeding, including the expenses and compensation of
any appraisers, will be determined by the court and assessed against the
Surviving Corporation, except that the court may, in its discretion, assess part
or all of those costs and expenses against any shareholder whose action in
demanding supplemental payment is found to be arbitrary, vexatious or not in
good faith. The court may award fees and expenses to an attorney for the
dissenting shareholders out of the amount, if any, awarded to such shareholders.
Fees and expenses of experts or attorneys may also be assessed against any
person who acted arbitrarily, vexatiously or not in good faith in bringing the
proceeding.


                                      32
<PAGE>
 
     UHS may withhold the remittance of the estimated fair value, plus interest,
for any shares owned by any person who was not a shareholder or who is
dissenting on behalf of a person who was not a beneficial owner on February 11,
1997, the date on which the proposed Merger was first announced to the public
(the "Public Announcement Date"). The Surviving Corporation will forward to any
such dissenting shareholder who has complied with all requirements in exercising
dissenters' rights the notice and all other materials sent after shareholder
approval of the Merger to all shareholders who have properly exercised
dissenters' rights, together with a statement of the reason for withholding the
remittance and an offer to pay the dissenting shareholder the amount listed in
the materials if the shareholder agrees to accept that amount in full
satisfaction. The shareholder may decline this offer and demand payment by
following the same procedure as that described for demand of supplemental
payment by shareholders who owned their shares as of the Public Announcement
Date. Any shareholder who did not own shares on the Public Announcement Date and
who fails properly to demand payment will be entitled only to the amount offered
by UHS. Upon proper demand by any such shareholder, rules and procedures
applicable in connection with receipt by UHS of the demand for supplemental
payment given by a dissenting shareholder who owned shares on the Public
Announcement Date will also apply to any shareholder properly giving a demand
but who did not own shares of record or beneficially on the Public Announcement
Date, except that any such shareholder is not entitled to receive any remittance
from UHS until the fair value of the shares, plus interest, has been determined
pursuant to such rules and procedures.

     Shareholders considering exercising dissenters' rights should bear in mind
that the fair value of their shares determined under Sections 302A.471 and
302A.473 of the MBCA could be more than, the same as or, in certain
circumstances, less than the consideration they would receive pursuant to the
Merger Agreement if they do not seek appraisal of their shares, and that the
opinion of any investment banking firm as to fairness, from a financial point of
view, is not an opinion as to fair value under Sections 302A.471 and 302A.473.

     Cash received pursuant to the exercise of dissenters' rights may be subject
to federal or state income tax.  See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."

     ANY HOLDER WHO FAILS TO COMPLY FULLY WITH THE STATUTORY PROCEDURE
SUMMARIZED ABOVE WILL FORFEIT HIS OR HER RIGHTS OF DISSENT AND WILL RECEIVE THE
MERGER CONSIDERATION FOR HIS OR HER SHARES. See Appendix C.


                             FINANCING THE MERGER

     If the Merger is consummated, the total amount required to pay the Merger
Consideration to the UHS shareholders, refinance indebtedness of UHS that will
be accelerated by reason of the Merger, and pay estimated fees and expenses of
MEDIQ and Merger Sub, will be approximately $144,000,000. Merger Sub will obtain
the necessary funds to consummate the Merger and pay all related fees and
expenses from the general corporate funds of MEDIQ, which intends to obtain such
funds from funds on deposit with its lenders and loans under its existing credit
agreement (the "Credit Agreement") with a group of lenders for which Banque
Nationale de Paris acts as Administrative Agent and NationsBank, N.A. acts as
Documentation Agent. Certain amendments to the Credit Agreement were made on
January 24, 1997, to increase the amount of the Credit Facility and otherwise
facilitate the financing of the Merger. The availability of loan proceeds under
the Credit Agreement to finance the Merger is subject to certain conditions set
forth in the Credit Agreement, including: (1) approval and adoption of the
Merger Agreement by the holders of a majority of the outstanding shares of UHS
Common Stock; (2) receipt of all necessary governmental approvals; and (3) the
satisfaction, before and after the Merger, of certain financial conditions set
forth in the Credit Agreement. UHS has been advised that MEDIQ expects such
financial conditions to be satisfied as of the Effective Time of the Merger.


                                      33
<PAGE>
 
     The Credit Agreement provides for four separate loans:  a Term A loan ($35
million), a Term B loan ($145 million), an Acquisition Revolver ($100 million)
and a Working Capital Revolver ($30 million).  As of March 14, 1997 there was
approximately $33,800,000 outstanding under the Term A loan, and approximately
$99,750,000 outstanding under the Term B loan.  There were no outstanding
balances under the Acquisition Revolver or the Working Capital Revolver.

     The loans bear interest at either the prime rate or at a Eurodollar rate
plus a factor. The factor changes quarterly based upon MEDIQ's leverage ratio,
within ranges of 1.125% to 1.75% for Term B prime rate loans, 2.75% to 3.25% for
Term B Eurodollar loans, 0.25% to 1.25% for other prime rate loans, and 1.75% to
2.75% for other Eurodollar loans. The loans are collateralized by substantially
all of the assets of MEDIQ and its principal subsidiaries. The Credit Agreement
requires the assets of UHS to be pledged to secure MEDIQ's obligations under the
Credit Agreement following the Merger.

     The Term A loan is payable in quarterly installments of $1.2 million
beginning December 31, 1996, through September 30, 2001, and in quarterly
installments of $2.75 million from December 31, 2001, through September 30,
2002. The Term B loan is payable in quarterly installments of $250,000 beginning
December 31, 1996, through September 30, 2002, quarterly installments of $13.0
million in fiscal 2003, and quarterly installments of $21.8 million in fiscal
2004. MEDIQ can borrow and repay under the Acquisition Revolver until March 31,
1998, in accordance with the Credit Agreement. On March 31, 1998, the
Acquisition Revolver converts to a term loan which is payable in quarterly
installments beginning on June 30, 1998. The first two such installments each
equal 5.0% of the converted balance, and each remaining quarterly payment equals
5.625% of the converted balance. The Working Capital Revolver terminates on
September 30, 2002, at which time all outstanding balances are due. The Credit
Agreement requires MEDIQ to maintain certain financial ratios and imposes
certain other financial and dividend limitations. The Credit Agreement requires
MEDIQ to pay to the lenders certain fees, to reimburse the lenders and their
agents for certain expenses, and to provide certain indemnities, all on terms
customary for similar credit facilities.

     MEDIQ anticipates that the indebtedness incurred by MEDIQ under the Credit
Agreement will be repaid from funds generated internally by MEDIQ and its
subsidiaries (including, after the Merger, if consummated, funds generated by
UHS), through additional borrowings, or through a combination of such sources.
No final decisions have been made concerning the method that MEDIQ will employ
to repay such indebtedness. Such decisions when made will be based on MEDIQ's
review from time to time of the advisability of particular actions, as well as
on prevailing interest rates and financial and other economic conditions.


                           UHS FINANCIAL PROJECTIONS

     During the course of inviting parties, including MEDIQ, to express an
interest in acquiring UHS, UHS made available certain information to all
interested parties (including MEDIQ) that included historical and projected
financial information. The financial portion of the information, which UHS
indicated it was making available to all interested parties, included the
following financial estimates for 1996 and financial projections for the years
1997 through 2001.

     Material assumptions on which the financial projections presented below are
based include the following:

     1.   Rental revenues are projected to grow at 10% annually in the years
          1998 through 2001. This future growth assumes the addition of four new
          offices per year as well as growth with existing customers and the
          addition of new customers. In 1997, the Company receives the
          incremental benefit of the BERS acquisition in addition to a 10%
          growth of base UHS revenues.

                                       34
<PAGE>
 
     2.   Sales revenue is projected to drop slightly in 1997 due to a
          continuing trend by a major vendor of disposables to market its
          products directly to some of the UHS's larger customers. Sales revenue
          is not projected to grow after 1997.

     3.   The direct costs associated with rental and repair of equipment are
          variable costs and are projected at 9.3% of rental revenue from 1997
          through 2001. All other rental costs (costs associated with operating
          district offices such as vehicles, computers and occupancy) are
          budgeted for no growth in 1997 and projected to grow at 9% annually
          from 1998 through 2001 in order to support continued revenue growth.

     4.   Rental depreciation reflects depreciation of the rental equipment
          portfolio and is dependent on new rental equipment purchases which are
          projected to increase gradually. The costs of new rental equipment are
          depreciated, on average, over six years.

     5.   Compensation and benefits (other than any district incentive
          compensation) for all sales people and district administration is
          projected to grow at 8% in each year from 1998 through 2001 over 1997
          budgeted amounts, reflecting the impact of inflation and growth in
          infrastructure. Corporate general and administrative costs (other than
          profit sharing expenses) are projected to grow at 4% in each year
          primarily reflecting inflationary growth. The projections take into
          consideration a district incentive of 2% of rental revenue after 1997
          and a corporate profit sharing plan equal to 11% of pre-bonus
          operating income in each year.

     6.   The average cost of borrowing on the UHS revolving credit facility is
          assumed to be approximately 8%.

     7.   Beginning in 1997, the projections assume a 42% federal and state tax
          rate.

     8.   Rental equipment purchases are estimated to be $13.5 million in 1996,
          $19.5 million in 1997 and $20.5 million in 1998. Purchases grow by
          $1.5 million each year from 1999 through 2001. Approximately 40% to
          45% of rental equipment purchases can be classified as maintenance
          expenditures (replacing equipment that is taken out of service) and
          the remainder represents incremental additions to the portfolio.

     9.   The projections do not assume any external financing, acquisitions,
          divestitures or material one-time events, including costs associated
          with the disposal of the Company's DPAP inventory, costs related to
          the Company's expense control initiatives and professional fees and
          Directors' compensation costs relating to the Board of Directors'
          review of strategic alternatives for enhancing shareholder value, all
          as described in the Company's Annual Report on Form 10-K for the year
          ended December 31, 1996 included as Appendix D hereto under the
          caption "Management's Discussion and Analysis of Financial Condition
          and Results of Operations."

     UHS does not as a matter of course make public any projections as to future
performance or earnings, and the projections set forth above are included in
this Proxy Statement only because the information was provided to MEDIQ. The
projections were not prepared with a view to public disclosure or compliance
with the published guidelines of the Commission or the guidelines established by
the American Institute of Certified Public Accountants regarding projections or
forecasts. UHS's internal operating projections are, in general, prepared solely
for internal use in connection with capital budgeting and other management
decisions and are subjective in many respects and thus susceptible to various
interpretations and periodic revisions based on actual experience and business
developments. The projections were based on a number of material assumptions
specified therein and summarized above. These assumptions are beyond the control
of UHS, MEDIQ or Merger Sub or their respective financial advisors, and require
a degree of economic forecasting (both general and specific to UHS's business)
that is inherently uncertain and subjective. None of UHS, MEDIQ or Merger Sub or
their respective financial advisors assumes any responsibility for the accuracy
of any of the projections. The inclusion of the foregoing projections should not
be regarded as an indication that UHS, MEDIQ or Merger Sub or any other person
who received such information considers it an accurate prediction of future
events. Neither UHS nor MEDIQ intends to update, revise or correct such
projections if they become inaccurate (even in the short term).

     The foregoing projections constitute "forward-looking statements" under the
Private Securities Litigation Reform Act of 1995 and involve risks and
uncertainties. The Company's actual results may differ significantly from those
discussed herein. Factors that might cause such a difference include, but are
not limited to, the effect of changing economic or business conditions,
increased utilization of the Bazooka bed, the impact of competition and other
risk factors described more fully in the Company's Annual Report on Form 10-K
for the year ended December 31, 1996 (included in this Proxy Statement as
Appendix D) under the captions "Industry Assessment," "Rental Equipment Build
Up" and "Business."

                         THE SUPPORT/VOTING AGREEMENTS

     Pursuant to the Support/Voting Agreements, certain members of UHS
management, specifically, Thomas A. Minner, Paul W. Larsen, Michael W. Bohman
and Duane R. Wenell (the "Supporting Stockholders") have severally agreed to
vote in favor of the Merger Agreement and Merger all shares of UHS Common Stock
that they owned on February 17, 1997, consisting of approximately 16.0% of the
aggregate number of shares outstanding as of such date.

     Each of the Supporting Stockholders has also agreed not to (i) sell,
contract to sell or otherwise dispose of, or enter into any contract, option or
other arrangement or understanding with respect to the sale, transfer, pledge,
assignment or other disposition of, shares to any person other than MEDIQ or
MEDIQ's designee, (ii) enter into any voting arrangement, whether by proxy,
voting agreement, voting trust, power-of-attorney or otherwise, with respect to
shares of UHS Common Stock or (iii) take any other action that would in any way
restrict, limit or interfere with the performance of its obligations hereunder
or the transactions contemplated hereby. Each of the Supporting Stockholders has
also agreed not to solicit, initiate or encourage (including by way of
furnishing information) and not to participate in any discussions or
negotiations regarding any Competing Transaction (as defined in the
Support/Voting Agreements) or vote in favor of any Competing Transaction.


          STOCK OWNERSHIP OF MANAGEMENT AND CERTAIN BENEFICIAL OWNERS

     The following table sets forth information regarding ownership of UHS
Common Stock (the only class of voting securities of the Company) as of February
15, 1997 by each person beneficially owning at least 5% of such securities, by
each director of UHS, by each of the executive officers of UHS, and by all
executive officers and directors as a group.

intends to retain earnings for use in the operation and expansion of its

                        DESCRIPTION OF UHS CAPITAL STOCK

     The authorized capital stock of the Company consists of 10,000,000 shares
of UHS Common Stock, $.01 par value, of which 5,372,421 shares were outstanding
on February 26, 1997; 100,000 shares of Series A Junior Participating Preferred
Stock, $.01 par value (the "Junior Preferred Shares"), no shares of which are
outstanding; and 4,900,000 shares of undesignated preferred stock, $.01 par
value, no shares of which are outstanding.

UHS Common Stock

     The holders of the UHS Common Stock are entitled to one vote for each share
held of record on all matters submitted to a vote of shareholders. There is no
cumulative voting for the election of directors so that the holders of more than
50% of the outstanding UHS Common Stock can elect directors. Subject to
preferences that may be applicable to any outstanding preferred stock, holders
of the UHS Common Stock are entitled to receive ratably such dividends as may be
declared by the Board of Directors out of funds legally available therefor and
in liquidation proceedings. Holders of UHS Common Stock have no preemptive or
subscription rights and there are no redemption rights with respect to such
shares. The outstanding shares of UHS Common Stock are fully paid and
nonassessable.

Undesignated Preferred Stock

     The Company's Board of Directors is authorized, without further shareholder
action, to issue preferred stock in one or more series and to fix the voting
rights, liquidation preferences, dividend rights, repurchase rights, conversion
rights, redemption rights and terms, including sinking fund provisions, and
certain other rights and preferences, of the preferred stock.

     Although there is no current intention to do so, the Board of Directors of
the Company may, without shareholder approval, issue shares of a class or series
of preferred stock with voting and conversion rights which could adversely
affect the voting power of the holders of UHS Common Stock and may have the
effect of delaying, deferring or preventing a change in control of the Company.

Provisions of the Company's Restated Articles and Bylaws
   and the Minnesota Business Corporation Act

     The existence of authorized but unissued preferred stock, described above,
and certain provisions of the Company's Restated Articles of Incorporation and
Bylaws and Minnesota law, described below, could have an anti-takeover effect.
These provisions are intended to provide management flexibility, to enhance the
likelihood of continuity and stability in the composition of the Company's Board
of Directors and in the policies formulated by the Board and to discourage an
unsolicited takeover of the Company if the Board determines that such a takeover
is not in the best interests of the Company and its shareholders. However, these
provisions could have the effect of discouraging certain attempts to acquire the
Company which could deprive the Company's shareholders of opportunities to sell
their shares of UHS Common Stock at prices higher than prevailing market prices.

     Pursuant to the Restated Articles of Incorporation and Bylaws, the Board of
Directors of the Company is divided into three classes serving staggered three-
year terms. As a result, at least two shareholders' meetings will generally be
required for shareholders to effect a change in control of the Board of
Directors.

     Section 302A.671 of the Minnesota Statutes applies, with certain
exceptions, to any acquisition of voting stock of the Company (from a person
other than the Company, and other than in connection with certain mergers and
exchanges to which the Company is a party) resulting in the beneficial ownership
of 20% or more of the voting stock then outstanding. Section 302A.671 requires
approval of any such acquisitions by a majority vote of the shareholders of the
Company prior to its consummation. In

                                       40
<PAGE>
 
general, shares acquired in the absence of such approval are denied voting
rights and are redeemable at their then fair market value by the Company within
30 days after the acquiring person has failed to give a timely information
statement to the Company or the date the shareholders voted not to grant voting
rights to the acquiring person's shares. Section 302A.671 does not apply to the
Merger.

     Section 302A.673 of the Minnesota Statutes generally prohibits any business
combination by the Company, or any subsidiary of the Company, with any
shareholder which purchases 10% or more of the Company's voting shares (an
"interested shareholder") within four years following such interested
shareholder's share acquisition date, unless the business combination is
approved by a committee of all of the disinterested members of the Board of
Directors of the Company before the interested shareholder's share acquisition
date. Section 302A.673 does not apply to the Merger.

Rights and Junior Preferred Shares

     On November 8, 1996, the Company adopted a shareholder rights plan under
which the Rights were declared as a dividend at the rate of one Right for each
share of UHS Common Stock held by shareholders of record at the close of
business on November 21, 1996. The Rights automatically accompany all shares of
UHS Common Stock outstanding and trade with them.

     Each Right entitles the holder to buy one 1/100th of a Junior Preferred
Share at a price of $40.00. However, the Rights are exercisable only if a person
or group acquires or makes a tender offer for 15% or more of the UHS Common
Stock. The Rights are redeemable at 1/10c per right at any time prior to the
acquisition of a 15% position. The Rights expire on Novemberu8, 2006.

     If a person or group acquires 15% or more of the UHS Common Stock (except
in connection with the Merger, as described below) each Right will entitle its
holder to purchase, at the Right's then-current exercise price, Junior Preferred
Shares having a market value of twice the Right's exercise price. If the Company
is acquired in a merger (except in connection with the Merger, as described
below) or sells 50% or more of its assets or earning power, each Right will
entitle its holder to purchase, at the Rights' then current exercise price, the
acquiring company's common stock having a market value of twice the Right's
exercise price.

     The Junior Preferred Shares purchasable upon exercise of the Rights will
not be redeemable. Each Junior Preferred Share will be entitled to a minimum
preferential quarterly dividend payment of $1.00 per share but will be entitled
to an aggregate dividend of 100 times the dividend declared per share of UHS
Common Stock. In the event of liquidation, the holders of the Junior Preferred
Shares will be entitled to a minimum preferential liquidation payment of $100.00
per share but will be entitled to an aggregate payment of 100 times the payment
made per share of UHS Common Stock. Each Junior Preferred Share will have 100
votes, voting together with shares of UHS Common Stock. Finally, in the event of
any merger, consolidation or other transaction in which the UHS Common Stock are
exchanged, each Junior Preferred Share will be entitled to receive 100 times the
amount received per share of UHS Common Stock. These rights are subject to
adjustment in the event of a stock dividend on the shares of UHS Common Stock or
a subdivision, combination or consolidation of the UHS Common Stock.

     The Rights are not currently exercisable and, pursuant to the Merger
Agreement, UHS has taken all action necessary (i) to render the Rights
inapplicable to the Merger and the transactions contemplated by the Merger
Agreement and (ii) to ensure that a "Distribution Date" (as defined in the
Rights Agreement) will not occur by reason of the announcement or consummation
of the Merger or any of the other transactions contemplated by the Merger
Agreement. The Rights will expire on the date of the Merger and thereafter the
shareholders of UHS will not have any further rights with respect thereto.

Transfer Agent and Registrar

     The Transfer Agent and Registrar with respect to the UHS Common Stock is
Norwest Bank Minnesota, N.A.


                             SHAREHOLDER PROPOSALS

     If the Merger is consummated, no public annual meetings of shareholders of
UHS will be held in the future.  If the Merger is not consummated, because the
date of any such annual meeting cannot currently be determined, shareholders
will be informed (by press release or other means determined reasonable by UHS)
of the date of such meeting and the date that shareholder proposals for
inclusion in the proxy material must be received by UHS, which proposals must
comply with the rules and regulations of the Commission then in effect.


                                 OTHER MATTERS

     The Board of Directors of UHS does not presently know of any matters to be
presented for consideration at the Special Meeting other than matters described
in the Notice of Special Meeting mailed together with this Proxy Statement, but
if other matters are presented, it is the intention of the persons named in the
accompanying proxy to vote on such matters in accordance with their best
judgment.  The proxy confers discretionary authority to vote only with respect
to matters that the Board of Directors of UHS did not know, within a reasonable
time before the mailing of these materials, were to be presented at the Special
Meeting.


                         COMPLIANCE WITH SECTION 16(a)
                     OF THE SECURITIES EXCHANGE ACT OF 1934

     Section 16(a) of the Exchange Act requires UHS's officers and directors and
persons who own more than ten percent of UHS Common Stock to file reports of
ownership and changes in ownership with the Commission.  These reporting persons
are also required to furnish UHS with copies of all reports they file.  Based
solely on its review of the copies of such forms received by it, or written
representations from certain reporting persons that no Forms 5 were required for
those persons, UHS believes that during its 1996 fiscal year all filing
requirements applicable to its officers, directors and greater than ten percent
shareholders were complied with.


                            INDEPENDENT ACCOUNTANTS

     The consolidated financial statements of UHS as of December 31, 1996 and
1995 and for the years ended December 31, 1996, 1995 and 1994, included in this
Proxy Statement, have been audited by Coopers & Lybrand L.L.P., independent
accountants.

     A representative of Coopers & Lybrand L.L.P. will be at the Special Meeting
to answer questions by shareholders and will have the opportunity to make a
statement if so desired.

       WHEREAS, Acquiror, Newco and the Company desire to effect a business
combination by means of a merger of Newco with and into the Company; and

       WHEREAS, the Boards of Directors of Acquiror, Newco and the Company have
approved, and deem it advisable and in the best interests of their respective
shareholders to consummate, the merger of Newco with and into the Company upon
the terms and subject to the conditions set forth herein.

       Section 1.1.  The Merger.  Subject to the satisfaction or waiver of the
                     ----------                                               
conditions set forth in Articles V and VI herein, on a date within five business
days following expiration or termination of the applicable waiting period
required by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations thereunder (the "HSR Act"), Newco will

       Section 1.2.  Effective Date and Time.  As promptly as practicable after

       (a) Subject to Section 4.2(c), at the Effective Time, the Articles of

of Incorporation.

       Section 1.6.  Cancellation of Company Shares.  Upon the terms and subject
                     ------------------------------                             
to the conditions of this Agreement, at the Effective Time, automatically by
virtue of the Merger and without any further action on the part of Acquiror, the
Company, the Surviving Corporation or the holders of any of the following
securities:

       (a) Each share (a "Share") of the common stock of the Company, $.01 par
   value (the "Common Stock"), together with the associated rights to purchase
   shares of Series A Junior Participating Preferred Stock, par value $.01 per
   share (the "Rights"), pursuant that certain Rights Agreement dated as of
   November 8, 1996 between the Company and Norwest Bank Minnesota N.A., as
   Rights Agent (the "Rights Agreement"), issued and outstanding immediately
   prior to the Effective Time, other than Shares cancelled pursuant to this
   Section 1.6(b) and Dissenting Shares (as defined in Section 1.7(b)), shall be
   cancelled, extinguished and converted into and become a right to receive
   $17.50 in net cash per Share without any interest thereon (the "Merger
   Consideration"), subject to adjustment for any stock dividend, subdivision,
   reclassification, recapitalization, split, combination or exchange occurring
   before the Effective Time.

       (b) Each Share (including the associated Rights) that is issued and
   outstanding immediately prior to the Effective Time and owned by Acquiror or
   any direct or indirect subsidiary or affiliate of Acquiror or by the Company
   or any direct or indirect subsidiary of the Company, shall be cancelled,
   extinguished and retired, and no payment of any consideration shall be made
   with respect thereto.

       (c) Each share of Newco's capital stock issued and outstanding
   immediately prior to the Effective Time shall be converted into one share of
   common stock of the Surviving Corporation.

       (d) As a result of their conversion pursuant to this Section 1.6(a), all
   Shares (including any associated Rights, but excluding any Dissenting Shares
   and any Shares described in this Section 1.6(b) issued and outstanding
   immediately before the Effective Time shall cease to be outstanding and shall
   automatically be canceled and retired, and each certificate ("Certificate")
   previously evidencing such Shares (other than Dissenting Shares and Shares
   described in this Section 1.6(b) ("Converted Shares") shall thereafter solely
   represent the right to receive the Merger Consideration pursuant to this
   Section 1.6(a) of this Agreement.  The holders of Certificates shall cease to
   have any rights with respect to such Converted Shares except as otherwise
   provided herein or by law.

                                      A-2

       Section 1.7.  Dissenting Shares.
                     ----------------- 

       (a) Notwithstanding any provision of this Agreement to the contrary, any
Shares held by a holder (a "Dissenting Shareholder") who has demanded and
perfected his demand for appraisal of his Shares in accordance with Sections 471
and 473 of the MBCA and as of the Effective Time has neither effectively
withdrawn nor lost his right to such appraisal shall not represent a right to
receive the aggregate Merger Consideration for such Shares pursuant to
Section 1.6 above, but in lieu thereof the holder thereof shall be entitled to
only such rights as are granted by the MBCA.  Acquiror shall make any and all
payments to holders of Shares with respect to such demands.

       (b) Notwithstanding the provisions of Section 1.7(a) above, if any
Dissenting Shareholder demanding appraisal of such Dissenting Shareholder's
Shares ("Dissenting Shares") under the MBCA shall effectively withdraw or lose
(through failure to perfect or otherwise) his right to appraisal, then as of the
Effective Time or the occurrence of such event, whichever later occurs, such
Dissenting Shares shall automatically be converted into and represent only the
right to receive the Merger Consideration as provided in Section 1.6 above upon
surrender of the certificate or certificates representing such Dissenting
Shares.

       (c) The Company shall give Acquiror prompt notice of any demands by a
Dissenting Shareholder for payment, or notices of intent to demand payment
received by the Company under Sections 473 of the MBCA and Acquiror shall have
the right to participate in all negotiations and proceedings with respect to
such demands.  The Company shall not, except with the prior written consent of
Acquiror (which will not be unreasonably withheld or delayed) or as otherwise
required by law, make any payment with respect to, or settle, or offer to
settle, any such demands.

       Section 1.8.  Company Plans.
                     ------------- 

       (a) Stock Options.  Upon the consummation of the Merger, each option to
           -------------                                                      
acquire Shares outstanding immediately prior to the Effective Time under the
Company's 1992 Long-Term Incentive and Stock Option Plan, as amended (the "ISO
Plan") and the Company's 1992 Directors' Stock Option Plan, as amended (the
"Directors' Plan"), whether vested or unvested (each, an "Option," collectively,
the "Options"), shall automatically become immediately vested and exercisable
and each holder of an Option shall have the right to receive from Acquiror a
cash payment (less applicable withholding taxes) in an aggregate amount equal to
the difference between the Merger Consideration less the exercise price per
Share applicable to such Option for all Shares subject to the Option as
expressly stated in the applicable stock option agreement or other agreement
(the "Option Consideration").  The Company shall take such other actions
(including, without limitation, giving requisite notices to holders of Options
advising them of such accelerated vesting and rights pursuant to this Section
1.8) as are necessary to fully advise holders of Options of their rights under
this Agreement and the Options and to facilitate their timely exercise of such
rights.  From and after the Effective Time, other than as expressly set forth in
this Section 1.8, no holder of an Option shall have any other rights in respect
thereof other than to receive payment for his Options equal to the Option
Consideration, and the Surviving Corporation shall take all reasonably necessary
actions to terminate the Company's stock option plans and similar arrangements.

       (b) Employee Stock Purchase Plan.  Outstanding purchase rights under the
           ----------------------------                                        
Company's 1992 Employee Stock Purchase Plan, as amended (the "ESPP"), shall be
exercised upon the earlier of (i) the next scheduled purchase date under the
ESPP or (ii) immediately prior to the Effective Time, and each participant in
the ESPP shall accordingly be issued Shares at that time which shall be
cancelled at the Effective Time and converted into the right to receive the
Merger Consideration for those Shares.  The ESPP shall terminate with such
exercise date, and no purchase rights shall be subsequently granted or exercised
under the Company ESPP.

       Section 1.9.  Surrender of Securities; Funding of Payments; Stock
                     ---------------------------------------------------
                     Transfer Books.
                     -------------- 

       (a) Pursuant to an agreement reasonably satisfactory to the Company and
Acquiror entered before the Effective Time, the Company shall designate a bank
or trust company reasonably acceptable to Acquiror to act as agent for the
holders of the Shares and Options (the "Exchange Agent") for the purpose 

                                      A-3
<PAGE>
 
of exchanging Certificates for the Merger Consideration and documents
representing Options (the "Option Agreements") for the Option Consideration. The
fees and expenses of the Exchange Agent shall be paid by Acquiror and Acquiror
shall indemnify the Exchange Agent and the Company against actions taken by the
Exchange Agent pursuant hereto other than for acts or omissions which constitute
willful misconduct or gross negligence, pursuant to the agreement with the
Exchange Agent.

       (b) At the Effective Time, Acquiror shall remit to the Exchange Agent an
amount equal to (i) the aggregate Merger Consideration and Option Consideration
necessary to pay the holders of the Converted Shares and Options  (collectively,
the "Payment Fund").

       (c) Acquiror agrees that, as soon as practicable after the Effective Time
and in no event later than five business days thereafter, the Surviving
Corporation shall cause the distribution to holders of record of the
Certificates and Option Agreements (as of the Effective Time) of a form of
letter of transmittal and other appropriate materials and instructions for use
in effecting the surrender of the Certificates for payment of the Merger
Consideration therefor and in effecting the surrender of the Option Agreements
for payment of the Option Consideration therefor.   In the event any Certificate
or Option Agreement shall have been lost or destroyed, the Exchange Agent,
subject to such other conditions as the Surviving Corporation may reasonably
impose (including the posting of an indemnity bond or other surety in favor of
the Surviving Corporation with respect to the Certificate alleged to be lost or
destroyed), shall be authorized to accept an affidavit from the record holder of
such Certificate or Option Agreement in a form reasonably satisfactory to
Acquiror.  Upon the surrender of each such Certificate formerly representing
Shares, together with such letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the Exchange Agent shall
pay to holders of such Certificates out of the Payment Fund the Merger
Consideration multiplied by the number of Converted Shares represented by such
Certificates, less any amounts required to be held pursuant to applicable tax
laws.  Upon the surrender of each such Option Agreement formerly representing
Options, together with a letter of transmittal, duly completed and validly
executed in accordance with the instructions thereto, the Exchange Agent shall
pay such holders the Option Consideration multiplied by the number of Shares for
which such Options were exercisable as of the Effective Time, less any amounts
required to be withheld pursuant to applicable tax laws.

       (d) If any portion of the Merger Consideration or Option Consideration is
to be paid to a person other than the person in whose name a Certificate or
Option Agreement is registered, it shall be a condition to such payment that
such Certificate or Option Agreement shall be surrendered and shall be properly
endorsed or shall be otherwise in proper form for transfer and that the person
requesting such payment shall have paid any transfer and other taxes required by
reason of such payment in a name other than that of the registered holder of the
certificate or instrument surrendered or shall have established to the
satisfaction of Acquiror and the Exchange Agent that such tax either has been
paid or is not payable.

       (e) At the Effective Time, the stock transfer books of the Company shall
be closed and there shall not be any further registration of transfers of Shares
thereafter on the records of the Company.

       (f) To the extent not immediately required for payment on surrendered
Shares and Options, proceeds in the Payment Fund shall be invested by the
Exchange Agent, as directed by the Surviving Corporation (as long as such
directions do not impair the rights of holders of Shares or Options), in direct
obligations of the United States of America, obligations for which the faith and
credit of the United States of America is pledged to provide for the payment of
principal and interest, commercial paper rated of the highest investment quality
by Moody's Investors Service, Inc. or Standard & Poor's Ratings Group, or
certificates of deposit issued by a commercial bank having at least $5 billion
in assets, and any net earnings with respect thereto shall be paid to the
Surviving Corporation as and when requested by the Surviving Corporation.

       (g) After the Effective Time, no dividends, interest or other
distributions shall be paid to the holder of any unsurrendered Certificates.

       (h) After the Effective Time, holders of Certificates shall cease to have
any rights as shareholders of the Company, except as provided herein or under
applicable state corporation law.  No 

                                      A-4
<PAGE>
 
interest shall be paid on any Merger Consideration or Option Consideration
payable to former holders of Shares or Options.

       (i) Promptly following the one-year anniversary date of the Effective
Date, the Exchange Agent shall return to the Surviving Corporation all of the
remaining Payment Fund, and the Exchange Agent's duties shall terminate.
Thereafter, each holder of a Certificate or an Option Agreement may surrender
the same to the Surviving Corporation and upon such surrender (subject to
applicable abandoned property, escheat or similar laws) shall receive the
applicable aggregate Merger Consideration and/or Option Consideration, as
applicable.  Notwithstanding the foregoing, neither the Exchange Agent nor any
party hereto shall be liable to any former holder of Shares or Options for any
amount delivered to a public official pursuant to applicable escheat or similar
law.

                                  ARTICLE II

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
                 ---------------------------------------------

       The Company represents and warrants to Acquiror that:

       Section 2.1.  Corporate Organization and Authorization.
                     ---------------------------------------- 

       (a) The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of Minnesota and has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business, and to enter into this Agreement and to carry out the
transactions contemplated hereby.

       (b) (i) The Company has all requisite governmental authorizations,
   certificates, licenses, consents and approvals required to carry on its
   business as presently conducted, except where the failure to possess such
   authorizations, certificates, licenses, consents and approvals (either
   individually or in the aggregate) would not have a Material Adverse Effect on
   the Company (as defined in Section 2.1(b)(ii)).  The Company is duly
   qualified to do business as a foreign corporation and is in good standing in
   each jurisdiction where the character of the property owned or leased by it
   or the nature of the activities conducted by it makes such qualification
   necessary, except where the failure to so qualify or to maintain such good
   standing (either in one jurisdiction or in the aggregate) would not have a
   Material Adverse Effect.

           (ii) For purposes of this Agreement, "Material Adverse Effect" shall
   mean with respect to the Company or Acquiror, as applicable, any effect that
   individually or when taken together with all similar effects (i) is material
   and adverse to the prospects, assets, financial position, results of
   operations or business of the Company and the Subsidiary taken as a whole, or
   Acquiror and its subsidiaries taken as a whole, respectively, or (ii) would
   materially impair the ability of the Company or Acquiror, respectively, to
   perform its obligations under this Agreement or otherwise materially threaten
   or materially impede the consummation of the Merger and the other
   transactions contemplated by this Agreement; provided, however, that Material
   Adverse Effect shall not be deemed to include the impact of (a) actions or
   omissions of the Company or Acquiror taken with the prior written consent of
   the Company or Acquiror, as applicable, in contemplation of the transactions
   contemplated hereby, and (b) the effects of the Merger (or any announcement
   with respect thereto) and compliance with the provisions of this Agreement on
   the operating performance or prospects of such party and its subsidiaries,
   including without limitation, with respect to the Company, any loss of
   customer relationships or employees following the announcement of the Merger.

       (c) The Company's only subsidiary is Biomedical Equipment Rental & Sales,
Inc., (the "Subsidiary") and since 1992 the Company has not had any subsidiary
other than the Subsidiary.  For purposes of this section, "subsidiary" means any
entity of which securities or other ownership interests having ordinary voting
power to elect a majority of the Board of Directors or other persons performing
similar functions are directly or indirectly owned by the Company.  Neither the
Company nor the Subsidiary (i) directly or indirectly owns, (ii) has agreed to
purchase or otherwise acquire or (iii) holds any interest convertible into or
exchangeable or exercisable for, 5% or more of the capital stock or other 

                                      A-5
<PAGE>
 
equity interest of any corporation, partnership, company, joint venture or other
business association or entity (other than the Company's ownership of the
capital stock of the Subsidiary). Except as set forth in Schedule 2.1(c), and
for any agreements, arrangements or commitments solely between the Company and
the Subsidiary, there are no agreements, arrangements or commitments of any
character (contingent or otherwise) pursuant to which any person is or may be
entitled to receive any payment based on the revenues or earnings, or calculated
in accordance therewith, of the Company or the Subsidiary. There are no voting
trusts, proxies or other agreements or understandings to which the Company or
the Subsidiary is a party or by which the Company or the Subsidiary is bound
with respect to the voting of any shares of capital stock of the Company or the
Subsidiary.

       (d) The Subsidiary is a corporation duly organized, validly existing and
in good standing under the laws of North Carolina and has all requisite
corporate power and authority to own, lease and operate its properties and to
carry on its business, and has all governmental authorizations, certificates,
licenses, consents and approvals required to carry on its business as presently
conducted, except where the failure to possess such authorizations,
certificates, licenses, consents and approvals (either individually or in the
aggregate) would not have a Material Adverse Effect on the Company.  The
Subsidiary is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction where the character of the property owned or
leased by it or the nature of the activities conducted by it makes such
qualification necessary, except where the failure to so qualify or to maintain
such good standing (either in one jurisdiction or in the aggregate) would not
have a Material Adverse Effect on the Company.

       (e) All of the outstanding capital stock of the Subsidiary (i) has been
validly issued, is fully paid and nonassessable and is not subject to preemptive
or similar rights and all such shares of capital stock were issued in material
compliance with all applicable federal and state securities laws, and (ii) is
owned by the Company free and clear of any lien or other encumbrance.  There are
no outstanding (i) securities of the Subsidiary convertible into or exchangeable
for shares of capital stock or other voting securities or ownership interests in
the Subsidiary or (ii) options or other rights to acquire from the Company or
the Subsidiary, and no other obligation of the Company or the Subsidiary to
issue, any capital stock, voting securities or other ownership interests in, or
any securities convertible into or exchangeable for, any capital stock, voting
securities or ownership interests in the Subsidiary (items in clauses (i) and
(ii) being referred to collectively as the "Subsidiary Securities").  There are
no outstanding obligations of the Company or the Subsidiary to repurchase,
redeem or otherwise acquire any outstanding Subsidiary Securities.

       (f) This Agreement has been duly authorized by the Board of Directors of
the Company, has been duly executed and delivered by the Company and, except for
obtaining the approval of the Company's shareholders at the Company Special
Meeting (as defined herein), no further corporate authorization on the part of
the Company is necessary to consummate the transactions contemplated by this
Agreement.

       (g) This Agreement constitutes a valid and binding agreement of the
Company and is enforceable against the Company in accordance with its terms,
except to the extent enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar laws relating to or affecting
creditors' rights generally and general equitable principles (whether considered
in a proceeding in equity or in law).

       (h) The copies of the respective Articles of Incorporation and Bylaws,
and all amendments thereto, of the Company and the Subsidiary heretofore
delivered to Acquiror are complete and true copies of such documents as in
effect on the date hereof.

       Section 2.2.  Capitalization.  The authorized capital stock of the
                     --------------                                      
Company consists of 10,000,000 shares of Common Stock, 100,000 shares of Series
A Junior Participating Preferred Stock, par value $.01 per share (the "Junior
Preferred Stock"), and 4,900,000 shares of undesignated preferred stock, par
value $.01 per share ("Undesignated Stock").  As of the date of this Agreement,
(a) 5,372,221 Shares were issued and outstanding, all of which have been duly
authorized, and are validly issued and outstanding, fully paid and
nonassessable; (b) no shares of Junior Preferred Stock were issued and
outstanding; (c) 540,867 Shares were reserved for issuance pursuant to
outstanding Options heretofore 

                                      A-6

granted under the ISO Plan and the Directors' Plan. Schedule 2.2 sets forth as
of the date of this Agreement a schedule showing (i) each outstanding Option and
the date it was granted; (ii) the number of Shares subject thereto as of the
Effective Date (assuming full acceleration of vesting as provided in such
Options and Section 1.8); (iii) the exercise price; and (iv) the method by which
the number of Shares issuable pursuant to Section 1.8(b) under the ESPP may be
determined. All of the Shares were issued in material compliance with all
applicable federal and state securities laws and none of the Shares were issued
in violation of any preemptive or similar rights. Except as described in this
Section 2.2 (including shares reserved under the ESPP), no shares of the capital
stock of the Company are reserved for issuance for any purpose. Except as set
forth above or in the Rights Agreement, there are no other shares of capital
stock or other equity securities, instruments or other rights of the Company
outstanding and no other outstanding options, warrants, rights to subscribe to
(including any preemptive rights), calls or commitments of any character
whatsoever to which the Company or the Subsidiary is a party or may be bound
requiring the issuance, transfer or sale of any shares of capital stock or other
equity securities of the Company or any securities or rights convertible into or
exchangeable or exercisable for any such shares or equity securities, and there
are no contracts, commitments, understandings or arrangements by which the
Company or the Subsidiary is or may become bound to issue additional shares of
its capital stock options, warrants or rights to purchase, redeem or acquire any
additional shares of its capital stock or securities convertible into or
exchangeable or exercisable for any such shares or other securities.

       Section 2.3.  Noncontravention.
                     ---------------- 

       (a) Subject to the expiration or termination of the applicable waiting
period required by the HSR Act, neither the execution or delivery of this
Agreement nor the consummation of the transactions contemplated hereby:

           (i) violates, conflicts with, or constitutes a default under, the
   Articles of Incorporation or Bylaws, as amended, of any of the Company or the
   Subsidiary; or

           (ii) assuming that all consents, approvals, orders or authorizations
   contemplated by subsection (b) below have been obtained and all filings
   described therein have been made, (A) violates or will violate any statute or
   law or any rule, regulation, order, judgment or decree of any court or
   governmental authority to which the Company or the Subsidiary is subject or
   (B)(with or without notice or lapse of time or both), except as disclosed on
   Schedule 2.3(a) hereto, constitutes a default or breach under, or gives to
   others any rights of termination, acceleration or modification of, any note,
   bond, mortgage, indenture, deed of trust, license, lease or other material
   agreement, instrument or obligation to which the Company or the Subsidiary is
   a party or by which either of them is bound.

       (b) Except for the expiration or termination of the applicable waiting
period under the HSR Act, and in connection with the MBCA, the Securities
Exchange Act of 1934, as amended (the "Exchange Act")), state securities or
"Blue Sky" laws or regulations (the "Blue Sky laws") and the Nasdaq Stock
Market, there is no other consent, approval, order or authorization of, or
filing with, or any permit from, or any notice to, any federal, governmental,
regulatory or administrative authority required to be obtained by the Company or
the Subsidiary for the execution of this Agreement by the Company and the
consummation of the transactions contemplated hereby.

       Section 2.4.  SEC Filings.
                     ----------- 

       (a) Prior to the execution of this Agreement, the Company has delivered

stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading and (y) complied as to
form in all material respects with the applicable laws and rules and regulations

       (b) The Company financial statements (including any footnotes thereto)
contained in the Company Public Reports and the Interim Financial Statements
were prepared in accordance with the published rules and regulations of the SEC
and generally accepted accounting principles applied on a consistent basis

except that the Interim Financial Statements do not contain any footnotes
thereto) and fairly presented the consolidated financial position of the Company

there has been no material adverse change in, and no event, loss, occurrence or
development in the business of the Company or the Subsidiary, taken as a whole,
that, taken together with other events, occurrences and developments with
respect to such business, has had or would reasonably be expected to have a
Material Adverse Effect on the Company.  Except as disclosed in the Company
Public Reports filed prior to the date of this Agreement or as contemplated in
this Agreement, since December 31, 1996, the Company and the Subsidiary have
conducted their respective businesses only in the ordinary course and in a
manner consistent with past practice.

       Section 2.6.  Legal Proceedings.  Except as set forth on Schedule 2.6
                     -----------------

any, claims, actions, suits, proceedings (arbitration or otherwise) or

prohibit, restrain or otherwise prevent the transactions contemplated hereby or
(ii) reasonably likely to result in a Material Adverse Effect on the Company if
adversely determined.  There are no judgments, decrees or orders issued by any

there has not been any declaration, setting aside or payment of any dividend or
any other distribution with respect to the Company's or the Subsidiary's capital
stock or any redemption, purchase or other acquisition of any of the Company's

paid (or the Company has paid on its behalf), or has set up an adequate reserve
for the payment of, all Taxes required to be paid in respect of the periods

Returns is true, complete and accurate in all material

any tax, assessment or governmental charge, except where such delinquency would
not have a Material Adverse Effect on the Company. There are no Tax liens upon
the assets of the Company or the Subsidiary except liens for Taxes not yet due
or being contested in good faith through appropriate proceedings. No deficiency
for any Taxes has been proposed, asserted or assessed against the Company or the
Subsidiary that has not been resolved or paid in full. No audits or other
administrative proceedings or court proceedings are presently pending with
regard to any material Taxes or Tax Returns of the Company or the Subsidiary. No
amount that could be received (whether in cash or property or the vesting of
property) as a result of any of the transactions contemplated by this Agreement
by any employee, officer or director of the Company or any of its affiliates who
is a "disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) under any employment, severance or termination
agreement, other compensation arrangement or company benefit plan currently in
effect would be an "excess parachute payment" (as such term is defined in
Section 280G(b)(1) of the Code). Neither the Company nor the Subsidiary has made
an election under section 341(f) of the Code. Neither the Company nor the
Subsidiary is required to make any adjustments under Section 481(a) of the code.
Neither the Company nor the Subsidiary is a party to any tax-sharing, allocation

   a group of entities.

       Section 2.10.  Absence of Undisclosed Liabilities.  All of the
                      ----------------------------------             
obligations or liabilities (whether accrued, absolute, contingent, unliquidated
or otherwise, whether due or to become due, and regardless of when asserted,
including Taxes (as defined in Section 2.9)) with respect to or based upon
transactions or events heretofore occurring ("Liabilities"), required to be
reflected on the latest balance sheet delivered to Acquiror pursuant to Section
2.4 (the "Latest Balance Sheet") in accordance with generally accepted

assets, operation, prospects or financial condition of the Company and the
Subsidiary, taken as a whole, except (a) as reflected on the Latest Balance
Sheet, (b) Liabilities which arose prior to the date of the Latest Balance Sheet
in the ordinary course of business and not required under generally accepted
accounting principals to be reflected on the Latest Balance Sheet, (c) current
Liabilities which have arisen after the date of the Latest Balance Sheet in the
ordinary course of business, and (d) as otherwise disclosed on Schedule 2.10.

       Section 2.11.  Compliance with Laws; Permits.   Each of the Company and

limitation, any state or federal acts (including rules and regulations
thereunder) regulating or otherwise affecting, equal employment opportunity,
employee health and safety or the environment), except where the failure to so
comply would not, individually or in the aggregate, have a Material Adverse
Effect on the Company; and no claims have been filed by any such governments or
agencies against the Company or the Subsidiary alleging such a violation of any
such law or regulation which have not been resolved to the satisfaction of such
governments or agencies.   Since December 31, 1994, neither the Company nor any
of its subsidiaries has received from any governmental entity any written
notification with respect to possible conflicts, defaults or violations of Laws,
except for written notices relating to possible conflicts, defaults or

                                      A-9
<PAGE>
 
violations that have not had and could not reasonably be expected to have a
Material Adverse Effect on the Company. Each of the Company and the Subsidiary
holds all of the permits, licenses, certificates and other authorizations of
foreign, federal, state and local governmental agencies required for the conduct
of its business ("Permits"), except where failure to obtain such authorizations
would not, individually or in the aggregate, have a Material Adverse Effect on
the Company.

cost of any Cleanup which, in the case of clauses (A) or (B), could have a
Material Adverse Effect on the Company.

                                   COVENANTS
                                   ---------

       Section 4.1.  Conduct of the Company Prior to the Effective Time.
                     -------------------------------------------------- 

       (a) No Solicitation; Other Offers.
           ----------------------------- 

           (i) From the date hereof until the termination of this Agreement or
   the Effective Date, whichever first occurs, the Company will not, and will
   cause the Subsidiary not to, and will use its best efforts to cause the
   officers, directors, employees, representatives and agents of the Company and
   the Subsidiary not to, directly or indirectly, solicit, initiate or encourage
   any inquiry, proposal, offer or indication of interest from any person that
   constitutes or would reasonably be expected to lead to any Acquisition
   Proposal (as hereinafter defined) or enter into discussions or negotiate with
   any person or entity in furtherance of any such inquiries or to obtain or
   approve any Acquisition Proposal, or agree to or endorse any Acquisition
   Proposal, and the Company shall immediately notify Acquiror of all relevant
   terms  of any such inquiries or proposals received by the Company or the
   Subsidiary or by any such officer, director, employee, representatives, or
   agents, relating to any of such matters, any material change in the details
   (including any amendments or proposed amendments) of any such inquiries or
   proposals, the identity of each of the persons or entities making such
   inquiries or proposals, and, if such inquiry or proposal is in writing, the
   Company shall immediately deliver or cause to be delivered to Acquiror a copy
   of such inquiry or proposal; provided, however, that if, prior to the
                                --------  -------                       
   Effective Time, the Company shall receive an unsolicited Acquisition Proposal
   that the Board of Directors of the Company, based upon the advice of its
   legal counsel, reasonably believes that it has a fiduciary duty to consider,
   then the Company, without violating this Agreement, may thereafter furnish
   information to and enter into discussions or negotiations with such third
   party.  Nothing contained in this Section 4.1(a) or any other provision of
   this Agreement shall prevent the Board of Directors of the Company or the
   Special Committee, after receiving an opinion of outside counsel to the
   effect that the Board of Directors is required to do so in order to discharge
   properly its fiduciary duties, from considering, negotiating, approving and
   recommending to the shareholders of the Company an unsolicited, bona fide
   written Acquisition Proposal which the Board of Directors of the Company
   determines in good faith (after consultation with its financial advisors) (A)
   would result in a transaction more favorable to the Company's shareholders
   than the transaction contemplated by this Agreement and (B) is made by a
   person financially capable of consummating such Acquisition Proposal (any
   such Acquisition Proposal being referred to herein as a "Superior Proposal").
   If the Board of Directors of the Company shall have resolved to accept or
   accepted a Superior Proposal then upon written notice to Acquiror, the
   Company may pursuant to Section 8.1(d) terminate this Agreement and the
   transactions contemplated hereby.  For purposes hereof, "Acquisition
   Proposal" means any proposal for a merger, consolidation or other business
   combination involving the Company or the acquisition of any equity interest
   in, or a substantial portion of the assets of the Company or the Subsidiary,
   other than the transactions contemplated by this Agreement.

           (ii) Upon any termination by the Company of this Agreement permitted
   by Section 4.1(a)(i), the Company shall pay to Acquiror the sum of $3,000,000
   (the "Break-Up Fee").  In such circumstances, the Break-Up Fee shall be
   deemed to include all costs and expenses of Acquiror.

       (b) Conduct of the Company's Business and Operations.  Except as
           ------------------------------------- ----------

the date hereof to the Effective Date, the Company covenants and agrees that:

   their present business organizations, keep available the services of their
   present officers and employees and preserve their relationships with
   customers, suppliers and others having business dealings with them. The
   Company shall, and shall cause the Subsidiary to:  (A) maintain insurance
   coverages and its books, accounts and records in the usual manner consistent
   with prior practices; (B) comply in all material respects with all laws,
   ordinances and regulations of governmental entities applicable to the Company
   and the Subsidiary; (C) maintain and keep its properties and equipment in
   good repair, working order and condition, ordinary wear and tear excepted;

   and commitments to which it is a party or by which it is bound, in each case
   other than where the failure to so maintain, comply or perform, either
   individually or in the aggregate, would result in a Material Adverse Effect
   on the Company;

           (ii) The Company shall not and shall not propose to:  (A) sell or
   pledge or agree to sell or pledge any capital stock owned by it in the
   Subsidiary; (B) amend its Articles of Incorporation or Bylaws; (C) split,

   acquire or agree to redeem, purchase or otherwise acquire any shares of the
   Company's capital stock;

   capital assets or any other assets other than in the ordinary course of
   business; (C) incur additional indebtedness or encumber or grant a security

   additional indebtedness, in any event in an amount not more than $600,000 in
   excess of the amount reflected on the Latest Balance Sheet) in the aggregate;
   (D) acquire or agree to acquire by merging or consolidating with, or by
   purchasing a equity interest in, or by any other manner, any business or any
   corporation, partnership, association or other business organization or
   division thereof, or otherwise acquire or agree to acquire any assets of any
   other person (other than the purchase or lease of assets from suppliers or
   vendors in the ordinary course of business consistent with past practice); or
   (E) enter into any contract, agreement, commitment or arrangement with
   respect to any of the foregoing;

           (iv) Except as disclosed on Schedule 4.1(b), the Company shall not,
   nor shall it permit the Subsidiary to (except as required to comply with
   applicable law): (A) adopt, enter into, terminate or amend any bonus, profit
   sharing, compensation, severance, termination, stock option, pension,
   retirement, deferred compensation, employment or other employee benefit plan,
   agreement, trust, fund or other arrangement for the benefit or welfare of any
   director, officer or current or former employee; (B) increase in any manner
   the compensation or fringe benefit of any director, officer or employee
   (except for normal increases in the ordinary course of business that are
   consistent with past practice and that, in the aggregate, do not result in a
   material increase in such employee's benefits or compensation relative to the
   level in effect prior to such amendment); (C) pay any benefit not 

                                      A-18

   provided under any existing plan or arrangement; (D) grant any awards under
   any bonus, incentive, performance or other compensation plan or arrangement
   or employee benefit plan (including, without limitation, the grant of stock
   options, stock appreciation rights, stock based or stock related awards,
   performance units or restricted stock, or the removal of existing
   restrictions in any benefit plans or agreements or awards made thereunder)
   (other than such plans and arrangements which are made in the ordinary course
   of business consistent with past practice); (E) take any action to fund or in
   any other way secure the payment of compensation or benefits under any
   employee plan, agreement, contract or arrangement or employee benefit plan
   other than in the ordinary course of business consistent with past practice;
   or (F) adopt, enter into, amend or terminate any contract, agreement,
   commitment or arrangement to do any of the foregoing;

           (v) The Company shall not, nor shall it permit the Subsidiary to,

   agreement or arrangement relating to any Acquisition Proposal or otherwise
   under any confidentiality, non-competition or other similar agreement;

           (vii)  the Company shall not, nor shall it permit the Subsidiary to,

       Section 4.2.  Additional Covenants of Acquiror, Newco and the Company.
                     ------------------------------------------------------- 

       (a) Employee Benefits.  As of the Effective Time, the employees of the
           -----------------                                                 
Company and the Subsidiary (the "Company Employees") shall continue employment
with the Surviving Corporation and its subsidiaries, respectively, in the same
positions and at the same level of wages and/or salary and without having
incurred a termination of employment or separation from service; provided,
however, except as may be specifically required by applicable law or any
contract, the Surviving Corporation and its subsidiaries shall not be obligated
to continue any employment relationship with any Company Employee for any period
of time. Acquiror, Newco and the Company agree that Company Employees will be
entitled to the policies and programs set forth on Schedule 4.2, to the extent
provided therein, and that Company Employees whose employment is terminated on
or after the Effective Date or within 12 months thereafter will receive
severance payments to the extent provided pursuant to policy attached hereto as
Schedule 4.2.  Acquiror agrees that Company Employees who remain employed by the
Surviving Corporation following the Merger shall be eligible to participate in
all plans, programs or policies then afforded to similarly situated employees of
Acquiror and its affiliated companies.   To the extent any employee benefit
plan, program or policy of Acquiror or its affiliates is made available to the
employees of the Surviving Corporation or its subsidiaries:  (i) service with
the Company and the Subsidiary by any Company Employee prior to the Effective
Time shall be credited in determining such employee's eligibility, vesting and
benefit levels (but not for accrual of benefits), and (ii) with respect to any
welfare benefit plans to which such employees may become eligible, Acquiror
shall cause such plans to provide credit for any co-payments or deductibles by
such employees and waive all pre-existing condition exclusions and waiting
periods, other than limitations or waiting periods that have not been satisfied
under any welfare plans maintained by the Company and the Subsidiary for Company
Employees prior to the Effective Time.

       (b) Confidentiality.  Prior to the Effective Time and after any
           ---------------                                            
termination of this Agreement, each party will hold, and will use its best
efforts to cause its officers, directors, employees, 

                                      A-19
<PAGE>
 
accountants, counsel, consultants, advisors and agents to hold, in confidence,
unless compelled to disclose by judicial or administrative process or by other
requirements of law, all confidential documents and information concerning the
other party furnished in connection with the transactions contemplated by this
Agreement, except to the extent that such information can be shown to have been
(i) previously known on a nonconfidential basis by such party (ii) in the public
domain through no fault of such party or (iii) later lawfully acquired by such
party from sources other than the other party; provided that such party may
                                               --------
disclose such information to its officers, directors, employees, accountants,
counsel, consultants, advisors and agents in connection with the transactions
contemplated by this Agreement and, in the case of Acquiror, to its lenders in
connection with obtaining the financing for the transactions contemplated by
this Agreement so long as such persons are informed by such party of the
confidential nature of such information and are directed by such party to treat
such information confidentially. Each party's obligation to hold any such
information in confidence shall be satisfied if it exercises the same care with
respect to such information as it would take to preserve the confidentiality of
its own similar information. If this Agreement is terminated, each party will,
and will cause its subsidiaries, to use its best efforts to cause their
respective officers, directors, employees, accountants, counsel, consultants,
advisors and agents to, destroy or deliver to the other party, upon request, all
documents and other materials, and all copies thereof, obtained by such party or
on its behalf from the other party in connection with this Agreement that are
subject to such confidence.

       (c) Indemnification; Directors' and Officers' Insurance.  Newco will
           ---------------------------------------------------             
(i) until the later of the six year anniversary date of the Effective Date or
the respective termination or expiration date of any existing Company or
Subsidiary indemnification agreement or arrangement, cause its Articles of
Incorporation and Bylaws to continue to provide indemnification provisions for
the benefit of those individuals who have served as directors or officers of the
Company or the Subsidiary at any time prior to the Effective Date which are
comparable to such provisions as are currently contained in the Company's or the
Subsidiary's, as applicable, Articles of Incorporation and Bylaws and
(ii) subject to the occurrence of the Effective Date, Acquiror hereby guarantees
unconditionally full payment and performance of the indemnification obligations
set forth in (i) above.  In the event the Surviving Corporation or any of its
successors or assigns (A) consolidates with or merges into any other person and
the Surviving Corporation shall not be the continuing or surviving corporation
or entity of such consolidation or merger or (B) transfers all or substantially
all of its properties and assets to any person, then, and in each such case,
proper provision shall be made so that the successors and assigns of the
Surviving Corporation shall assume the obligations set forth in this Section
4.2(c).  Acquiror shall, or shall cause the Surviving Corporation to, obtain and
maintain in effect for not less than six years after the Effective Date, the
current directors' and officers' liability insurance policies maintained by the
Company (provided that Acquiror or the Surviving Corporation may substitute
therefore a policy or policies of at least the same coverage containing similar
terms and conditions so long as no lapse in coverage occurs as a result of such
substitution) with respect to all matters, including the transactions
contemplated hereby, occurring prior to, and including the Effective Date;
provided that in no event shall Acquiror or the Surviving Company be required to
expend more than 250% of the current annual premiums paid by the Company for
such coverage (the "Maximum Premium"); and provided, further, that if Acquiror
or the Surviving Corporation is unable to obtain the amount of insurance
required by this Section 4.2(c) for such aggregate premium, Acquiror of the
Surviving Corporation shall obtain as much insurance as can be obtained for an
annual premium not in excess of the Maximum Premium.   Acquiror will, promptly
after the Effective Time, confirm to each such officer and director in writing
that it has undertaken to perform such obligations.

       (d) Conduct of Business Pending the Merger.  Prior to the Effective Date,
           --------------------------------------                               
unless otherwise contemplated or permitted by this Agreement:  (a) each of the
Company and Acquiror shall not, and shall cause its subsidiaries not to take, or
agree in writing or otherwise to take, any actions that would (i) make any
representation or warranty of the Company or Acquiror, respectively, or its
subsidiaries contained in this Agreement untrue or incorrect so as to cause the
conditions set forth in Articles V and VI hereof not to be fulfilled as of the
Effective Date or (ii) result in any of the other conditions of this Agreement
not being satisfied as of the Effective Date.  The Company's sole remedy (except
as otherwise expressly provided in this Merger Agreement) for any breach of this
Section 4.2(d) shall be injunctive relief.

<PAGE>
 
       (e) Access to Information.  The Company will (and will cause each of its
           ---------------------                                               
respective representatives to) afford to Acquiror (or representatives of
Acquiror, including without limitation directors, officers and employees of the
Acquiror and their affiliates and counsel, accountants and other professionals
retained by Acquiror) such access throughout the period prior to the earlier of
the termination of this Agreement or the Effective Time to books, records
(including without limitation tax returns and work papers of independent
auditors), agreements, properties (including for the purpose of making any
reasonable environmental investigation), personnel, suppliers and franchisees as
Acquiror reasonably requests from the Company.

       (f) HSR Act.  The Company and Acquiror shall use their best efforts to
           -------                                                           
file as soon as reasonably practicable notifications under the HSR Act in
connection with the Merger and the transactions contemplated hereby and to
respond as promptly as practicable to any inquiries received from the Federal
Trade Commission (the "FTC") or the Antitrust Division of the Department of
Justice (the "Antitrust Division") for additional information or documentation
and to respond as promptly as practicable to all inquiries and requests received
from any State Attorney General or any court, administrative agency or
commission or other governmental authority or instrumentality, domestic or
foreign (each, a "Governmental Entity"), in connection with antitrust matters.
The Company and Acquiror shall take such actions as are necessary to overcome
any objections which may be raised by the FTC or Antitrust Division.

       (g) Best Efforts.  Acquiror and the Company will each use its best
           ------------

conditions set forth in Articles V and VI, and to consummate the Merger on the
terms and conditions set forth in this Agreement.

       (h) Certain Filings.  The Company and Acquiror shall use their best
           ---------------                                                
efforts to cooperate with one another in determining whether any action by or in
respect of, or filing with, any governmental body, agency or official, or
authority is required, or any actions, consents, approvals or waivers are
required to be obtained from parties to any material contracts, in connection
with the consummation of the transactions contemplated by this Agreement and in
seeking to timely obtain any such actions, consents, approvals or waivers, or
making any such filings or furnishing information required in connection
therewith.

       (i) Public Announcements.   The initial press release relating to this
           --------------------                                              
Agreement shall be a joint press release and thereafter Acquiror and the Company
will consult with each other before issuing any press release or making any
public statement with respect to this Agreement and the transactions
contemplated hereby and, will not issue any such press release or make any such
public statement without the prior consent of the other party, which consent
shall not be unreasonably withheld; provided, however, that a party may, without
the prior consent of the other party, issue such press release or make such
public statement as may upon the advice of counsel be required by law, any
securities exchange or the National Association of Securities Dealers, Inc. if
it has used all reasonable efforts to consult with the other party.

       (j) Special Meeting. The Company shall take all action necessary, in
           ---------------

convene a special meeting of the holders of the Shares ("Special Meeting") as

a Superior Proposal and determined pursuant to Section 4.1(a), in the exercise
of its fiduciary duties, not to recommend that holders of the Shares approve the
Merger and this Agreement and shall have paid to Acquiror the Break-Up Fee.  The
Board of Directors of the Company and the Special Committee will, subject to its
fiduciary obligations, recommend that holders of the Shares vote in favor of and
approve the Merger and this Agreement at the Special Meeting.

       (k) Proxy Statement.

March 18, 1997



Special Committee of the Board of Directors
Universal Hospital Services, Inc.
1250 Northland Plaza
3800 West 80th Street
Bloomington, MN 55431

Gentlemen:

You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the outstanding shares of Common Stock (the "Shares") of
Universal Hospital Services, Inc. ("UHS" or the "Company"), of the $17.50 per
Share in cash into which each outstanding Share of the Company is proposed to be
converted pursuant to the terms of the proposed merger (the "Merger") of the
Company with PRN Merger Corporation ("Acquisition Subsidiary"), a wholly-owned
subsidiary of Mediq Inc. ("Acquiror"). The terms of the Merger are set forth in
the Agreement and Plan of Merger, dated as of February 10, 1997, by and among
the Company, Acquisition Subsidiary and Acquiror (the "Merger Agreement").

Piper Jaffray Inc. ("Piper Jaffray"), as a customary part of its investment
banking business, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, underwritings and
secondary distributions of securities, private placements, and valuations for
estate, corporate and other purposes. Piper Jaffray is currently acting as
financial advisor to the Special Committee of the Board of Directors of the
Company in connection with the Merger, for which the Company will pay a fee that
is contingent upon the consummation of the Merger. For our services in rendering
this opinion, the Company will pay us a fee that is not contingent upon the
consummation of the Merger. The Company has also agree to indemnify us against
certain liabilities in connection with this engagement. In the past, we have
provided certain investment banking services to UHS. Piper Jaffray makes a
market in UHS Common Stock and provides research coverage on the Company. Karen
Bohn, a Managing Director and the Chief Administrative Officer of Piper Jaffray
Companies, Inc., the parent of Piper Jaffray Inc., is a director of the Company
and a member of the Special Committee of the Board of Directors.

In arriving at our opinion, we have undertaken such reviews, analyses and
inquiries as we deemed necessary and appropriate under the circumstances. Among
other things, we have:

(i)    reviewed the Merger Agreement;

(ii)   reviewed the Annual Reports on Form 10-K for UHS for the three fiscal
       years ended December 31, 1995;

(iii)  reviewed the Quarterly Reports on Form 10-Q for UHS for the quarters
       ended September 30, 1996, June 30, 1996, and March 31, 1996;

(iv)   reviewed estimated financial results for the Company for the fiscal year
       ended December 31, 1996 and five-year financial forecasts for UHS
       prepared by the Company management for the years 1997 through 2001;

Special Committee of the Board of Directors
Universal Hospital Services, Inc.
March 18, 1997



(v)    visited the headquarters and the Minneapolis facility of UHS and
       conducted discussions with certain members of senior management of UHS
       concerning topics such as the financial condition, operating performance
       and balance sheet of UHS, the prospects for the Company and the
       background and rationale of the proposed Merger;

(vi)   conducted discussions with members of the Special Committee of the
       Board of Directors and the entire Board of Directors of the Company;

(vii)  reviewed the historical prices and trading activity for the Company
       Common Stock;

(viii) reviewed the financial terms, to the extent publicly available, of
       certain comparable merger and acquisition transactions which we deemed
       relevant;

(ix)   performed discounted cash flow analysis on the five-year financial
       forecasts for UHS furnished by UHS management;

(x)    analyzed the premiums paid in recent public company acquisitions; and

(xi)   compared certain financial data of UHS with certain financial and
       securities data of companies deemed similar to UHS or representative of
       the business sector in which UHS operates.

We have relied upon and assumed the accuracy, completeness and fairness of the
financial statements and other information provided by UHS or otherwise made
available to us and have not attempted independently to verify such information.
We have assumed, in reliance upon the assurances of UHS management, that the
information provided pertaining to UHS has been prepared on a reasonable basis
in accordance with industry practice and, with respect to financial planning
data, reflects the best currently available estimates and judgement of UHS's
management as to the expected future financial performance of UHS, and that the
management of UHS is not aware of any information or facts that would make the
information provided to us incomplete or misleading.  Without limiting the
generality of the foregoing, for the purpose of this opinion, we have assumed
that UHS is not a party to any pending transaction, including external
financing, recapitalizations, acquisitions or mergers discussions, other than
the Merger or in the ordinary course of business. We have also assumed that
there have been no material changes in the Company's assets, financial
condition, results of operations, business or prospects since the date of the
last financial statements made available to us.

In arriving at our opinion, we have not performed any appraisals or valuations
of specific assets or liabilities of UHS, have not been furnished with any such
appraisals or valuations, have made no physical inspection of the properties or
assets of the Company and express no opinion regarding the liquidation value of
UHS.

Without limiting the generality of the foregoing, we have undertaken no
independent analysis of any pending or threatened litigation, possible
unasserted claims or other contingent liabilities, to which either UHS or its
affiliates is a party or may be subject and at UHS's direction and with its
consent, our opinion makes no assumption concerning and therefore does not
consider, the possible assertion of claims, outcomes or damages arising out of
any such matters.

Our opinion is necessarily based upon information available to us, facts and
circumstances and economic, market and other conditions as they exist and are
subject to evaluation on the date hereof; events occurring after the date hereof
could materially affect the assumptions used in preparing this opinion. We are
not expressing any opinion herein as to the prices at which shares of Company
Common Stock have traded or at which such shares may trade at any future time.

This opinion is furnished pursuant to our engagement letter dated January 3,
1997. Except with respect to the use of this opinion in connection with the
proxy statement relating to the Merger, this opinion may not be used or referred
to by the Company or quoted or disclosed to any person in any manner without our
prior written consent. This opinion is not intended to be and shall not be
deemed to be a recommendation to any shareholder of the Company as to how to
vote with respect to the Merger.

Based upon and subject to the foregoing and based upon such other factors as we
consider relevant, it is our opinion that, as of the date hereof, the cash
consideration to be received by shareholders of the Company pursuant to the
Merger Agreement is fair, from a financial point of view, to the shareholders as
of the date hereof.

Sincerely,

PIPER JAFFRAY INC.

   SECTIONS 302A.471 AND 302A.473 OF THE MINNESOTA BUSINESS CORPORATION ACT -
                          DISSENTERS' APPRAISAL RIGHTS


302A.471. Rights of dissenting shareholders

     Subdivision 1.  Actions creating rights.  A shareholder of a corporation
may dissent from, and obtain payment for the fair value of the shareholder's
shares in the event of, any of the following corporate actions:

     (a) An amendment of the articles that materially and adversely affects the
rights or preferences of the shares of the dissenting shareholder in that it:

     (1) alters or abolishes a preferential right of the shares;

     (2) creates, alters, or abolishes a right in respect of the redemption of
the shares, including a provision respecting a sinking fund for the redemption
or repurchase of the shares;

     (3) alters or abolishes a preemptive right of the holder of the shares to
acquire shares, securities other than shares, or rights to purchase shares or
securities other than shares;

     (4) excludes or limits the right of a shareholder to vote on a matter, or
to cumulate votes, except as the right may be excluded or limited through the
authorization or issuance of securities of an existing or new class or series
with similar or different voting rights; except that an amendment to the
articles of an issuing public corporation that provides that section 302A.671
does not apply to a control share acquisition does not give rise to the right to
obtain payment under this section;

     (b) A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,
subdivision 1, or a disposition in dissolution described in section 302A.725,
subdivision 2, or a disposition pursuant to an order of a court, or a
disposition for cash on terms requiring that all or substantially all of the net
proceeds of disposition be distributed to the shareholders in accordance with
their respective interests within one year after the date of disposition;

     (c) A plan of merger, whether under this chapter or under chapter 322B, to
which the corporation is a party, except as provided in subdivision 3;

     (d) A plan of exchange, whether under this chapter or under chapter 322B,
to which the corporation is a party as the corporation whose shares will be
acquired by the acquiring corporation, if the shares of the shareholder are
entitled to be voted on the plan; or

     (e) Any other corporate action taken pursuant to a shareholder vote with
respect to which the articles, the bylaws, or a resolution approved by the board
directs that dissenting shareholders may obtain payment for their shares.

     Subd. 2.  Beneficial owners.  (a) A shareholder shall not assert
dissenters' rights as to less than all of the shares registered in the name of
the shareholder, unless the shareholder dissents with respect to all the shares
that are beneficially owned by another person but registered in the name of the
shareholder and discloses the name and address of each beneficial owner on whose
behalf the shareholder dissents.  In that event, the rights of the dissenter
shall be determined as if the shares as 

                                      C-1
<PAGE>
 
to which the shareholder has dissented and the other shares were registered in
the names of different shareholders.

     (b) The beneficial owner of shares who is not the shareholder may assert
dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or before the assertion of the rights a written consent of the
shareholder.

     Subd. 3.  Rights not to apply.  Unless the articles, the bylaws, or a
resolution approved by the board otherwise provide, the right to obtain payment
under this section does not apply to a shareholder of the surviving corporation
in a merger, if the shares of the shareholder are not entitled to be voted on
the merger.

     Subd. 4.  Other rights.  The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside or
rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.


302A.473. Procedures for asserting dissenters' rights

     Subdivision 1.  Definitions.  (a) For purposes of this section, the terms
defined in this subdivision have the meanings given them.

     (b) "Corporation" means the issuer of the shares held by a dissenter before
the corporate action referred to in section 302A.471, subdivision 1 or the
successor by merger of that issuer.

     (c) "Fair value of the shares" means the value of the shares of a
corporation immediately before the effective date of the corporate action
referred to in section 302A.471, subdivision 1.

     (d) "Interest" means interest commencing five days after the effective date
of the corporate action referred to in section 302A.471, subdivision 1, up to
and including the date of payment, calculated at the rate provided in section
549.09 for interest on verdicts and judgments.

     Subd. 2.  Notice of action.  If a corporation calls a shareholder meeting
at which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.

     Subd. 3.  Notice of dissent.  If the proposed action must be approved by
the shareholders, a shareholder who wishes to exercise dissenters' rights must
file with the corporation before the vote on the proposed action a written
notice of intent to demand the fair value of the shares owned by the shareholder
and must not vote the shares in favor of the proposed action.

     Subd. 4.  Notice of procedure; deposit of shares.  (a) After the proposed
action has been approved by the board and, if necessary, the shareholders, the
corporation shall send to all shareholders who have complied with subdivision 3
and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:

     (1) The address to which a demand for payment and certificates of
certificated shares must be sent in order to obtain payment and the date by
which they must be received;

     (2) Any restrictions on transfer of uncertificated shares that will apply
after the demand for payment is received;

                                      C-2
<PAGE>
 
     (3) A form to be used to certify the date on which the shareholder, or the
beneficial owner on whose behalf the shareholder dissents, acquired the shares
or an interest in them and to demand payment; and

     (4) A copy of section 302A.471 and this section and a brief description of
the procedures to be followed under these sections.

     (b) In order to receive the fair value of the shares, a dissenting
shareholder must demand payment and deposit certificated shares or comply with
any restrictions on transfer of uncertificated shares within 30 days after the
notice required by paragraph (a) was given, but the dissenter retains all other
rights of a shareholder until the proposed action takes effect.

     Subd. 5.  Payment; return of shares.  (a) After the corporate action takes
effect, or after the corporation receives a valid demand for payment, whichever
is later, the corporation shall remit to each dissenting shareholder who has
complied with subdivisions 3 and 4 the amount the corporation estimates to be
the fair value of the shares, plus interest, accompanied by:

     (1) The corporation's closing balance sheet and statement of income for a
fiscal year ending not more than 16 months before the effective date of the
corporate action, together With the latest available interim financial
statements;

     (2) An estimate by the corporation of the fair value of the shares and a
brief description of the method used to reach the estimate; and

     (3) A copy of section 302A.471 and this section, and a brief description of
the procedure to be followed in demanding supplemental payment.

     (b) The corporation may withhold the remittance described in paragraph (a)
from a person who was not a shareholder on the date the action dissented from
was first announced to the public or who is dissenting on behalf of a person who
was not a beneficial owner on that date.  If the dissenter has complied with
subdivisions 3 and 4, the corporation shall forward to the dissenter the
materials described in paragraph (a) a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction.
The dissenter may decline the offer and demand payment under subdivision 6.
Failure to do so entitles the dissenter only to the amount offered.  If the
dissenter makes demand, subdivisions 7 and 8 apply.

     (c) If the corporation fails to remit payment within 60 days of the deposit
of certificates or the imposition of transfer restrictions on uncertificated
shares, it shall return all deposited certificates and cancel all transfer
restrictions.  However, the corporation may again give notice under subdivision
4 and require deposit or restrict transfer at a later time.

     Subd. 6.  Supplemental payment; demand.  If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference.  Otherwise, a dissenter is entitled only to
the amount remitted by the corporation.

     Subd. 7.  Petition; determination.  If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest.  The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the

                                      C-3
<PAGE>
 
petition in the county in this state in which the last registered office of the
constituent corporation was located.  The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation.  The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of 180 civil procedure.  Nonresidents of this state may be served by
registered or certified mail or by publication as provided by law.  Except as
otherwise provided, the rules of civil procedure apply to this proceeding.  The
jurisdiction of the court is plenary and exclusive.  The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares.  The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter.  The fair value of the shares as determined by the court is binding
on all shareholders, wherever located.  A dissenter is entitled to judgment in
cash for the amount by which the fair value of the shares as determined by the
court, plus interest, exceeds the amount, if any, remitted under subdivision 5,
but shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.

     Subd. 8.  Costs; fees; expenses.  (a) The court shall determine the costs
and expenses of a proceeding under subdivision 7, including the reasonable
expenses and compensation of any appraisers appointed by the court, and shall
assess those costs and expenses against the corporation, except that the court
may assess part or all of those costs and expenses against a dissenter whose
action in demanding payment under subdivision 6 is found to be arbitrary,
vexatious, or not in good faith.

     (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable.  These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.

     (c) The court may award, in its discretion, fees and expenses to an
attorney for the dissenters out of the amount awarded to the dissenters, if any.

   Universal Hospital Services, Inc. provides movable medical equipment to more
than 3,100 hospitals and various other health care providers principally through
Pay-Per-Use/TM/ equipment management programs. The Company believes that
Pay-Per-Use rental is more cost effective than purchase, lease or fixed-term
rental of medical equipment for at least a portion of hospitals' and other
health care providers' medical equipment needs. Under the Company's rental
programs, health care providers may be charged a per use rental fee when
equipment is used, based on daily use per patient, or may be charged under
alternative fee arrangements. The Company's customers also receive a full range
of related support services, including equipment delivery, training, technical
and educational support, inspection, maintenance and documentation. In addition,
the Company engages in the sale of related disposable supplies. Health care
providers have access to the Company's pool of over 52,000 pieces of movable
medical equipment in five primary equipment categories-critical care,
monitoring, newborn care, respiratory therapy and specialty beds. The Company
currently operates through 46 district offices and eight regional service
centers, serving customers in 50 states and the District of Columbia.

Market Overview

   The United States health care system includes approximately 5,200 acute care
community hospitals and a variety of other health care providers such as nursing
homes, surgicenters, subacute care facilities, specialty clinics and home health
care providers. These hospitals and other health care providers normally spend a
substantial sum on obtaining capital equipment, including movable medical
equipment. Hospitals have a number of options in obtaining this equipment,
including purchase, lease and rental. Historically, hospitals have favored the
purchase option in meeting a substantial portion of their movable capital
equipment needs.

   The Company believes that a variety of trends favor rental as an alternative
to purchase or lease. Principal among these trends are the substantial cost
containment pressures under which hospitals and other health care providers
currently operate. These pressures have increased greatly during the past decade
as a result of federal regulations that have significantly affected the extent
of reimbursement under Medicare's prospective payment system, and the Company
believes that these pressures will continue to intensify. Changes to the
Medicare program adopted in 1991, and being phased in over a 10-year period, are
resulting in reimbursement for medical equipment costs at rates established by
the Health Care Financing Administration, and these rates may not reflect
hospitals' actual equipment costs. In addition, the Company believes that other
third party payors of medical expenses have followed or will follow the federal
government in limiting reimbursement for medical equipment costs. These would
include, but are not limited to, preferred provider arrangements, discounted fee
arrangements and "capitated" (fixed patient care reimbursement) managed care
arrangements. The Company believes that various current legislative proposals
will continue movement toward health care related consolidations, acceleration
of managed care and the formation of integrated delivery systems. The Company
also believes that the current reform effort will focus on cost containment in
health care and may reduce levels of reimbursement by Medicare as well as other
third party payors. See "Third Party Reimbursement" below.

   The Company believes that, as a result of these cost containment pressures,
hospitals and other health care providers will continue to seek to reduce their
capital expenditures, including expenditures on movable capital equipment. These
reductions, however, may mean that health care providers do not have sufficient
equipment to meet peak demands or the capital resources to replace existing
equipment with more current medical technology. In addition, since the Medicare
system is, to an increasing extent, reimbursing health care providers at fixed
rates unrelated to actual capital costs, hospitals and other health care
providers have an incentive to manage their capital costs more efficiently.
Hospitals may better manage their capital costs by replacing fixed capital costs
with variable operating costs. In the case of movable medical equipment, these
fixed costs include equipment acquisition costs and the substantial costs
associated with all services necessary to support the equipment. Consequently,
many of these entities are renting equipment to meet certain of their needs,
rather than incurring the substantial capital related costs associated with
owning or leasing equipment for which they may not be reimbursed during non-use
periods.
                                      
                                      D-3
<PAGE>
 
   In addition, the average hospital "census" (the number of patients filling
the available bed days) has declined in recent years, due to a reduction in
average length of hospital stay. This reduction has resulted from implementation
of the prospective payment system, an increase in "capitated" managed care and
preferred provider arrangements and an increase in the amount of care provided
outside of the acute care hospital setting. The Company believes this census
decrease has not resulted in a proportional decline in hospitals' equipment use,
since the most intensive level of care is generally delivered during the early
days of hospitalization and during outpatient procedures. These factors,
together with routine fluctuations in hospital occupancy, have placed increasing
pressures on hospitals to reduce equipment costs and maximize utilization of
medical equipment. Accordingly, the Company believes that the flexibility
afforded by equipment rental has become increasingly important. Pay-Per-Use
rental also allows hospitals to offer new technology to their physicians and
patients without the investment normally required to purchase or lease and
without the risk of obsolescence.

   The Company also believes that the increasing amount of patient care being
provided in "alternate care" settings (any care provided outside of inpatient
hospital care) provides additional opportunities for its equipment management
programs. The Company provides these programs wherever medical equipment is
being used to provide patient care. Alternate care providers, such as nursing
homes, surgicenters, subacute care facilities, outpatient centers, home care
providers and others, are facing the same cost containment pressures and
changing reimbursement programs as hospitals and have the same incentives to
manage their medical equipment costs more efficiently.

   As a result of cost, reimbursement, and standardization pressures, and
utilization and obsolescence risks, health care providers are becoming more
sophisticated in their medical equipment procurement decisions. Health care
providers increasingly are seeking ways to reduce costs and to manage equipment
levels at optimum utilization in order to maximize operating margins. In
determining whether to purchase, lease or rent equipment, health care providers
may consider anticipated utilization levels of equipment, the costs of
maintenance and repairs, storage, obsolescence and opportunity costs. The
Company believes that such analyses often show that Pay-Per-Use rental programs
increase the efficiency of equipment utilization, reduce ownership costs and
enhance operating margins.

Business Strategy

   The Company's strategy is to achieve continued market penetration and growth
by: (i) increasing business conducted with existing customers and markets; (ii)
establishing additional district offices in new geographic markets; (iii) adding
new product offerings and equipment lines; (iv) developing business with new
customers in the alternate care market; and (v) providing comprehensive total
equipment management programs to its customers.

   Increase Business with Existing Customers and Markets. The Company seeks to
increase the amount of business it conducts with existing customers by providing
additional equipment to these customers and reaching additional departments
within its existing hospital base. Because these customers are familiar with the
Company's programs and their benefits, the Company believes that its existing
customer base represents a significant expansion opportunity. The Company also
plans expansion through further penetration of the markets it currently serves
by establishing new relationships with additional hospitals and health care
providers .

   Establish New District Offices. The Company intends to establish three to
four new district offices each year over the next several years. In choosing
locations for its district offices, the Company considers the nature and extent
of the customer market, demographics and vendor relationships. While the major
metropolitan areas will remain a primary focus for expansion, regional clusters
of hospitals are also expected to provide attractive expansion opportunities.

   The Company completed the acquisition of Biomedical Equipment Rental and
Sales, Inc. (BERS) on August 13, 1996. See "Completed Acquisition" under
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
                      
                                      D-4
<PAGE>
                                       
   Add New Product Offerings and Equipment Lines. The Company seeks to expand
its business by adding new product categories and equipment lines and is
continually evaluating new products for inclusion in its equipment rental
inventory and for expansion of its product sales offering.

   Develop Business with New Customers in the Alternate Care Market. The Company
plans to expand through business development with alternate care providers such
as home care, subacute and long term care facilities, and  surgicenters. As the
average length of stay in acute care hospitals has continued to shorten, the
Company believes that growth opportunities exist in those alternate care
settings where patient care is being provided.

   Provide Total Equipment Management Programs. The Company intends to offer to
its customers additional total equipment management programs called Asset
Management Partnership Programs ("AMP Programs"). In these programs, the
Company provides, maintains, manages and tracks substantially all, or a
significant portion, of the movable medical equipment within the customer
facility or organization. These total equipment management programs allow health
care providers to improve the quality of their patient care by having all
appropriate medical equipment available when and where it is needed, while
controlling their costs through improved utilization and efficiency.

Equipment Management Programs

   The Company seeks to assist hospitals and other health care providers manage
their medical equipment costs more effectively while providing them with movable
medical equipment and related services. The components of the Company's
equipment management programs include:

   Pay-Per-Use. The Company principally provides its equipment on a Pay-Per-Use
basis under which customers are charged per daily patient use. The Company
believes that Pay-Per-Use rental is typically more cost effective than purchase,
lease or fixed-term rental of medical equipment. Under Pay-Per-Use rental,
health care providers can gain access to the latest medical equipment without
the large capital outlays and significant costs associated with the purchase and
maintenance of medical equipment and without the risks related to equipment
obsolescence. By using Pay-Per-Use rental rather than purchase, lease or fixed-
term rental, hospitals and other health care providers obtain the cash flow
advantage of paying for medical equipment only when there are corresponding
patient charges.

   Full Service. The Company emphasizes the full-service features of its Pay-
Per-Use equipment management programs. The Company's per-use rental fee includes
24-hour-a-day, 365-day-a-year delivery, provision of "patient ready" equipment,
technical support and training in equipment use by qualified personnel. This fee
also includes regular inspections and maintenance of all equipment rented from
the Company, including the documentation of such inspections and maintenance
through the Company's Rental Equipment Documentation System ("REDS") and the
Operator Error Identification System ("OEIS"). The Company maintains a total
service history of any rented equipment, which includes inspection, repair and
modification activities for the entire life of the unit. The Company also offers
an optional software package that allows a particular hospital to track
location, utilization and availability of all equipment rented, owned or leased
by that hospital. Together, these services allow health care providers to
eliminate many of the major overhead costs associated with the ownership or
lease of medical equipment.

   Equipment Utilization. The Company's equipment management strategy is to
promote Pay-Per-Use programs as a means of better managing medical equipment
needs while contributing to overall cost containment. The Company seeks to
allocate its pool of rental equipment efficiently among its customers by
continually monitoring customers' equipment utilization levels. The Company
reviews customer utilization routinely and, depending on utilization level, may
adjust the Pay-Per-Use fee or redeploy the equipment. This system benefits
customers by permitting them to obtain a lower per-use rental fee in the event
of higher utilization efficiency and benefits the Company as it attempts to
maximize the utilization of the equipment in inventory. See "Pricing of Pay-Per-
Use Programs" below.
             
                                      D-5
<PAGE>
 
   Asset Management Partnership Programs (AMP Programs). The Company has
developed relationships with some of its largest customers to help them achieve
substantially higher utilization rates and levels of efficiency for their
organizations. In some instances, the scope of the relationship has evolved into
comprehensive equipment management programs referred to as AMP Programs. In
these programs, the Company provides, maintains, manages and tracks
substantially all of the movable medical equipment within the customer's
facility or organization. The Company's AMP Programs allow health care providers
to improve the quality of their patient care by having all appropriate medical
equipment available when it is needed, while controlling their costs through
improved utilization and efficiency.

   Equipment Selection. The Company seeks equipment that has characteristics
which favor the rental of such equipment, including equipment movability, high
or fluctuating utilization, service intensiveness and obsolescence risk. The
Company purchases what it believes to be state-of-the-art equipment from
manufacturers with a reputation for quality. The Company generally purchases
from a number of different manufacturers to address the diversity of customer
demands with a special emphasis on equipment which lowers patient care costs
while improving quality of care and treatment outcomes. In addition, the
Company's product evaluation committee meets regularly to consider new products
as they become available and, when appropriate, approves new products for
acquisition.
                         
   Customer Responsiveness. The Company's operational structure is designed to
enable it to respond quickly to a customer's needs. Through its district
offices, the Company maintains both local inventories of medical equipment and a
system-wide inventory network which are designed to assure access to a broad
range of medical equipment. The Company's district offices are typically located
close enough to the customers they serve to allow equipment to be delivered and
ready for use generally within two hours of a request. The Company emphasizes
long-term customer relationships and seeks to develop and maintain strong
customer loyalty.

Customer Relationship

   The Company's equipment management programs are flexible arrangements through
which customers may obtain equipment on a Pay-Per-Use basis when they need it
and pay for equipment only when it is used. Customers may also obtain equipment
under alternative rental fee arrangements, such as on a daily, weekly or monthly
rental basis. When the Company's customers request a piece of equipment, the
Company provides the equipment in "patient-ready" condition. Upon delivery,
each piece of rented equipment is logged into the Company's tracking system as
being placed with the particular customer. The Company provides the customer
with information as to per-use or other rental rates at or prior to delivery of
the equipment, and these rates are generally effective for a three month period.
The Company generally does not use written agreements with its customers but
emphasizes continuous contact and shared information with each customer. Under
the Company's Pay-Per-Use programs, the customer is responsible for keeping a
record of each equipment use and reporting the use to the Company on a monthly
basis. Many customers report equipment utilization in conjunction with their
patient billing procedures. The Company bills each customer monthly based on
this reported usage. The customer is under no obligation to use the equipment
and may request that the Company remove the equipment at any time.
Correspondingly, the Company may remove equipment or raise the per-use rental
fee if it is under-utilized. The Company actively monitors the accounts
receivable performance of its customers.
 
Acquisition of Equipment Inventory

   The Company purchases medical equipment in the areas of critical care,
monitoring, newborn care, respiratory therapy and specialty beds. The Company
generally acquires equipment for its inventory pool having characteristics which
favor the rental of such equipment. Principal among these characteristics are
equipment movability, high or fluctuating utilization levels, service
intensiveness and anticipated obsolescence. Of additional consideration is the
relative safety of and the risks associated with such equipment. The Company
purchases what it believes to be state-of-the-art equipment from manufacturers
with a reputation for quality and functionally tests each piece of medical
equipment added to its inventory to determine that the equipment is working
properly.

                                      D-6
<PAGE>
 
     Equipment acquisitions may be made to expand the Company's pool of existing
medical equipment or to add new medical equipment technologies to the Company's
existing rental pool mix. The Company considers historical utilization levels,
anticipated customer demand, life cycle phase of the equipment and vendor
relationships before acquiring such equipment in order generally to avoid
speculative purchases. In the case of new technologies, the Company has
established a product evaluation committee to consider new technologies as they
become available. This evaluation process for new products involves many of the
review criteria set forth above as well as an overall evaluation of the
potential market demand for the new product.

     As of December 31, 1996, the Company had more than 52,000 pieces of
equipment available for use by its customers. The following is a list of
principal types of medical equipment available to the Company's customers:

</TABLE>

     The Company currently acquires substantially all of its medical equipment
from approximately 60 suppliers. The Company's five largest suppliers of medical
equipment, which supplied approximately 54.3 percent of the Company's medical
equipment purchases for the year ended December 31, 1996, are: Kendall Company;
Imed Corporation; Baxter Healthcare Corporation; Sims Deltec, Inc.; and Abbott
Laboratories. Although the identity of the top ten suppliers remains relatively
constant from year to year, the relative ranking of suppliers within this group
may vary over time. The Company believes that alternative sources of medical
equipment are available to the Company should they be needed.

     The Company seeks to ensure availability of equipment at favorable prices.
Although the Company does not generally enter into long-term fixed price
contracts with suppliers of its equipment, the Company may receive price
discounts related to the volume of its purchases. In order to receive strong
vendor support throughout the areas in which it does business, the Company seeks
to structure its equipment purchases to ensure credit to local representatives
of those vendors.

     The purchase price for equipment generally ranges from $1,000 to $25,000,
with some complete monitoring systems costing more than $1,000,000. The Company
finances the acquisition of its medical equipment inventory with internally
generated funds and unsecured borrowings. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

Pricing of Pay-Per-Use Programs

     The Company's pricing strategy is designed to generate a pay-back period
that is substantially shorter than the useful life of a particular piece of
equipment, thereby reducing the Company's obsolescence risk on its inventory
pool. The Company seeks to set its Pay-Per-Use or other rental rates to recoup
the equipment's purchase price generally within 15 to 18 months and to recoup
related costs within a specified number of additional months. These related
costs include accessories and service support activities required to maintain
equipment viability (e.g., maintenance, repairs, modifications, back-up support
and inspections). On a customer-specific basis, the Company then develops a per-
usage or other rental rate for a given piece of equipment which takes into
consideration the customer's needs with respect to equipment type, equipment
utilization, length of placement, frequency and extent of support services and
volume of business. This per-usage or other rental rate is designed not only to
recoup costs but also to provide the Company a targeted financial return on its
investment for the particular category of equipment. Service requirements and
Pay-Per-Use rates are generally reviewed on a quarterly basis and rates may be
adjusted as the customer's service needs or utilization levels vary from
expected levels. This evaluation process enables the Company to continuously
monitor actual revenues as compared to targeted return objectives.

Distributor Arrangement with SleepNet Corporation

     In January 1994, the Company entered into a distributor agreement with
SleepNet Corporation (the "SleepNet Corporation Agreement") providing the
Company with national distribution rights to two products introduced by SleepNet
Corporation: the Bazooka System, an innovative portable specialty bed providing
low air loss therapy for the treatment of pressure ulcers, and the Demand
Positive Airway Pressure (DPAP), a device designed to treat adult obstructive
sleep apnea. The Bazooka System and the DPAP device are currently the only
products manufactured and marketed by SleepNet Corporation. The Bazooka System
has been included in the Company's equipment rental programs since May 1994, and
the Company began distributing the DPAP device in February 1995. The DPAP device
was not offered as part of the Company's equipment rental programs.

     On February 28, 1996, SleepNet Corporation terminated its exclusive
distributor agreement with the Company.

     The Company's arrangement with SleepNet Corporation differed from the
Company's usual equipment acquisition methodology in that the Company's
purchases of Bazooka Systems under the SleepNet Corporation Agreement exceeded
the volumes needed by the Company to meet current customer demand. The Company
believes that, as of December 31, 1996, an aggregate of approximately $2.8
million of such equipment exceeded normal levels maintained by the Company.

     The Company experienced declining sales of DPAP devices during 1996.
Because market acceptance of the DPAP devices did not meet expectations, the
Company's ongoing quarterly assessment resulted in a right-down of $1,030,500 in
the second quarter and a charge of $1,182,545 in the fourth quarter of 1996 to
write-off the remaining carrying value of DPAP inventory and associated supplies
and demo units. The DPAP devices were disposed of in early 1997.

Sales of Related Disposables/Medical Supplies and Equipment

     In order to serve its customers fully, the Company sells disposable medical
supplies used in conjunction with the medical equipment it rents. Examples of
such disposable items include tubing and cassettes for infusion devices. The
Company believes that hospitals purchase disposables from the Company due to the
convenience of obtaining equipment and related supplies from one source and the
anticipated cost-savings resulting from acquiring disposables only on an as-
needed basis. The Company currently acquires substantially all of its rental-
related medical disposables from approximately 50 suppliers. The five largest
current suppliers of disposables to the Company, accounting for over 72 percent
of the Company's disposable purchases for the year ended 1996, are: Gaymar
Industries, Inc; Kendall Healthcare Products Company; Graseby, Inc.; IVAC, Inc;
and Select Medical. The Company believes that alternative purchasing sources of
disposable medical supplies are available to the Company, if necessary.

     The Company also sells used medical equipment that is no longer required in
its equipment rental pool, primarily to various non-hospital purchasers.

Inventory Tracking System

     The Company tracks the history of each piece of equipment in its inventory
on an IBM AS/400 centralized computer system located at its corporate
headquarters. This system provides immediate access to historical equipment
information by the use of remote terminals located in the corporate headquarters
and in each of the Company's district offices and regional service centers. Data
on length of placement, transfers, modifications, repairs, maintenance and
inspections are included on the system. This information is kept for the life of
the equipment and is used extensively for the establishment of preventative
maintenance and safety testing programs and the improvement of equipment
performance. Information as to a customer's rental equipment is also provided to
the customer through the Company's Rental Equipment Documentation System (REDS)
Program in order to help that customer meet its equipment documentation needs
under applicable standards and regulations. In addition, this system is used to
track the utilization levels of each piece of equipment. By keeping extensive
utilization records, the Company endeavors to maximize the utilization of all
equipment in its inventory.

Maintenance

     The Company maintains control over the functional testing and safety of all
equipment through its technical staff. Prior to placing equipment with a
customer, the Company applies testing standards designed to ensure the safety of
all such equipment. The Company conducts regular inspections of the equipment
either at one of the Company's district offices or regional service centers, or
on-site at the hospital. The Company provides all necessary repairs and
maintenance of its equipment. In order to assist hospitals and other health care
providers in meeting their equipment documentation needs for purposes of
applicable standards or regulations, the Company maintains a complete record of
all inspections, maintenance and repairs on its REDS Program. See "Inventory
Tracking System" above and "Regulation of Medical Equipment" below.

     The Company's equipment is generally covered by manufacturers' warranties,
which typically warrant repairs for a period of three to twelve months from the
date of purchase. Because the Company employs manufacturer-trained personnel for
the technical support of its equipment, a significant portion of repair and
maintenance of the Company's equipment is conducted by the Company's employees.

Maximization of Useful Life and Disposal of Equipment

     The Company seeks to maximize the useful life of its equipment by renting
its older equipment inventory at lower rental rates or bundling such older
equipment with newer equipment in rental programs with price incentives to the
customer. When pieces of the Company's medical equipment inventory are no longer
required or desired, such pieces may be sold.

Marketing

     The Company markets its Pay-Per-Use equipment management programs primarily
through its direct sales force, which consisted of 94 promotional sales
representatives as of December 31, 1996. In its marketing efforts to hospitals,
the Company primarily targets key decision makers, such as materials managers,
department heads and directors of purchasing, nursing and central supply, as
well as administrators, chief executive officers and chief financial officers.
In its marketing efforts to other health care providers, the Company also
targets key operational and administrative decision makers. The Company also
promotes its programs and services to hospital and health care provider groups
and associations. The Company develops and provides its direct sales force with
a variety of materials designed to support its promotional efforts. The Company
also uses direct mail advertising to supplement this activity, as well as
specifically targeted trade journal advertising.

     From time to time, the Company has developed specific marketing programs
intended to address current market demands. The most significant of such
programs includes the Company's "New Realities" program, which demonstrates the
economic justification for Pay-Per-Use Rentals, the AMP Program, which presents
hospitals with a total management approach to equipment needs, the REDS Program
which responds to the equipment documentation and tracking needs of health care
providers as a result of standards set by the Joint Commission on Accreditation
of Healthcare Organizations (JCAHO) and the Safe Medical Devices Act of 1990,
and the Operator Error Identification System, which responds to JCAHO
requirements regarding equipment operator training. See "Regulation of Medical
Equipment" below.

The Company's District Offices

     The Company currently operates through 46 district offices, serving
customers in 50 states and the District of Columbia. District offices are
typically staffed by a district manager, one or more promotional sales
representatives, an administrative assistant and delivery and service personnel
to support customers' needs and district operations. District offices are
responsible for marketing, billing and collection efforts, equipment delivery,
inservice training, and equipment inspection, maintenance and repair work.
Complementing the district offices are eight regional service centers, which
provide more sophisticated maintenance and repair on equipment. The following
table shows each district office location and its opening date:

Regulation of Medical Equipment

     The Company's customers are subject to documentation and safety reporting
standards with respect to the medical equipment they use, as established by the
following organizations and laws: the Joint Commission on Accreditation of
Healthcare Organizations; the Association for Advancement of Medical
Instrumentation; and the Safe Medical Devices Act of 1990 ("SMDA"). Some states
and municipalities also have similar regulations. The Company's REDS and OEIS
programs are specifically designed to help customers meet their documentation
and reporting needs under such standards and laws. The Company also monitors
changes in law and accommodates the needs of customers by providing specific
product information and manufacturers' addresses and contacts to these customers
upon their request. Manufacturers of the Company's medical equipment are subject
to regulation by agencies and organizations such as the Food and Drug
Administration ("FDA"), Underwriters Laboratories, the National Fire Protection
Association and the Canadian Standards Association. The Company believes that
all medical equipment it rents conforms to these regulations.

                                     D-11

<PAGE>
 
   The SMDA expanded the FDA's authority to regulate medical devices. The SMDA
requires manufacturers, distributors and end-users to report information which
"reasonably suggests" the probability that a medical device caused or
contributed to the death, serious injury or serious illness of a patient. The
Company works with its customers to assist them in meeting their reporting
obligations under the SMDA. Although the Company does not believe that it is
subject to the SMDA or its reporting requirements, it is possible that the
Company may be deemed to be a "distributor" of medical equipment under the
SMDA and would then be subject to the reporting obligations and related
liabilities thereunder.

   An additional equipment tracking regulation was added to the SMDA on August
29, 1993 which requires the Company to provide information to the manufacturer
regarding the permanent disposal of medical rental equipment and notification of
any change in ownership of certain categories of devices. The Company's medical
tracking systems have been reviewed by the FDA and found to be in substantial
compliance with these regulations.

   In July 1995, the FDA published a working draft of the Current Good
Manufacturing Practices ("CGMP") final rules which may become available in 1997.
Under these proposed final rules, the Company may have additional reporting
requirements to the FDA and to original equipment manufacturers relative to the
repair and servicing of the rental equipment it provides. The Company believes
that the tracking systems it utilizes will be sufficient to allow it to conform
to the additional regulations, if they are enacted.

Third Party Reimbursement

   The Company's business may be significantly affected by, and the success of
its growth strategies depends on, the availability and nature of reimbursements
to hospitals and other health care providers for their medical equipment costs
under federal programs such as Medicare, and by other third party payors. Under
its prospective payment system adopted in 1983 and later modified in 1991, the
Health Care Financing Administration ("HCFA"), which determines Medicare
reimbursement levels, reimburses hospitals for medical treatment at fixed rates
according to diagnostic related groups ("DRG's") without regard to actual cost.
Under this system of reimbursement, Medicare-related equipment costs are
reimbursed in a single, fixed-rate, per-discharge reimbursement. This system,
and subsequent modifications, is being phased in over a 10 year period. As a
result of the prospective payment system, the manner in which hospitals incur
equipment costs (whether through purchase, lease or rental) does not impact the
extent of hospitals' reimbursement. Since the Medicare system, to an increasing
extent, reimburses health care providers at fixed rates unrelated to actual
equipment costs, hospitals have an incentive to manage their capital costs more
efficiently and effectively. The Company believes that hospitals will continue
to benefit from cost-containment and cost-efficiency measures, such as
converting existing fixed equipment costs to variable costs through Pay-Per-Use
rental and improving efficiency through AMP Programs.

   Hospitals and other health care providers are also facing increased cost
containment pressures from public and private insurers and other managed care
providers, such as health maintenance organizations ("HMO's"), preferred
provider organizations ("PPO's") and managed fee-for-service plans, as these
organizations attempt to reduce the cost and utilization of health care
services. The Company believes that these payors have followed or will follow
the federal government in limiting reimbursement for medical equipment costs
through preferred provider contracts, discounted fee arrangements and
"capitated" (fixed patient care reimbursement) managed care arrangements. In
addition to promoting managed care plans, employers are increasingly self
funding their benefit programs and shifting costs to employees through increased
deductibles, copayments and employee contributions. The Company believes that
these cost reduction efforts will place additional pressures on health care
providers' operating margins and will encourage efficient equipment management
practices, such as Pay-Per-Use rental.

                                     D-12
<PAGE>
 
   Various legislative proposals currently before Congress provide, among other
things, for a reduction in the growth in Medicare and Medicaid spending over the
next several years. If enacted, these proposals may result in reduced payments
to hospitals, physicians and home health care providers (including reimbursement
payments for capital equipment), increased utilization of managed care and
increased Medicare premiums. The Company believes that pending and future health
care initiatives will continue movement toward health care related
consolidations, acceleration of managed care and the formation of integrated
delivery systems. The Company is unable to predict what, if any, additional
government regulations, legislation or initiatives or changes by other third
party payors affecting reimbursement or other matters which influence decisions
to obtain or utilize medical equipment may be enacted or effected and what
impact such regulations, legislation, initiatives or changes may have on the
Company's results of operations.

Liability and Insurance

   Although the Company does not manufacture any medical equipment, the
Company's business entails the risk of claims related to the rental and sale of
medical equipment. In addition, the Company's servicing and repair activity with
respect to its rental equipment and its instruction of hospital employees with
respect to the equipment's use are additional sources of potential claims. The
Company has had no recent experience with any significant claims; however, any
such claims, if made, could have an adverse impact on the Company. The Company
maintains general liability coverage, including product liability insurance and
excess liability coverage. Both policies are subject to annual renewal. The
Company believes that its current insurance coverage is adequate. There is no
assurance, however, that claims exceeding such coverage will not be made or that
the Company will be able to continue to obtain liability insurance at acceptable
levels of cost and coverage.

Competition

   The Company believes that the strongest competition to its programs is the
purchase alternative for obtaining movable medical equipment. Currently, many
hospitals and health care providers view rental primarily as a means of meeting
short-term or peak supplemental needs, rather than as a long-term alternative to
purchase. Although the Company believes that it can demonstrate the cost-
effectiveness of renting medical equipment on a long-term Pay-Per-Use basis, the
Company believes that many hospitals and health care providers will continue to
purchase a substantial portion of their movable medical equipment.

   The Company has one principal competitor in the medical equipment rental
business: Mediq/PRN, a subsidiary of MEDIQ Incorporated, based in Pennsauken,
New Jersey. Other competition consists of smaller regional companies and medical
equipment dealers who rent equipment to augment their medical equipment sales.
The Company believes that it can effectively compete with any of these entities
in the geographic regions in which both the Company and these entities operate.

Service Marks and Trade Names

   The Company uses the "UHS" and "Universal Hospital Services" names as trade
names and as service marks in connection with the Company's rental of medical
equipment.  The Company has registered these and other marks as service marks
with the United States Patent and Trademark Office.

Employees

   As of December 31, 1996, UHS had 384 employees, including 355 full-time and
29 part-time employees.  Of such employees, 94 are promotional sales
representatives, 27 are technical support personnel, 74 are employed in the
areas of corporate and marketing and 189 are UHS district office support
personnel.

   None of the Company's employees is covered by a collective bargaining
agreement, and the Company has experienced no work stoppages to date.

(1)  As a result of refinancing and early retirement of debt, the Company wrote
     off $153,760 (net of tax benefit of $108,000) of debt placement costs
     during 1992.

(2)  Earnings per share of common stock is calculated by dividing net income,
     less redeemable preferred stock dividends and the increase in the
     redeemable preferred stock redemption premium, by the weighted average of
     common and common equivalent shares outstanding during the year. Common
     equivalent shares include the dilutive effect of stock options. The
     increases in the redeemable preferred stock redemption premium and the
     amount of redeemable preferred stock dividends were $193,094 for the year
     ended December 31, 1992. The redeemable preferred stock was retired during
     1992.

(3)  No common stock cash dividends have been declared or paid by the Company.

General

  The following discussion addresses the financial condition of the Company and
its consolidated subsidiary, Biomedical Equipment Rental and Sales, Inc.
(BERS), as of December 31, 1996 and the results of operations and cash flows for
the years ended December 31, 1996, 1995 and 1994. This discussion should be read
in conjunction with the financial statements included elsewhere herein and the
Management's Discussion and Analysis and Financial sections of the Company's
previously filed Form 10-Q's.

  Safe Harbor Statement under the Private Securities Litigation Reform Act of
1995: Statements in this filing looking forward in time involve risks and
uncertainties, including, but not limited to, the effect of changing economic or
business conditions, increased utilization of the Bazooka bed, the impact of
competition and other risk factors described more fully below under the captions
"Industry Assessment" and "Rental Equipment Build Up" and the "Business" section
of this Form 10-K.

Revenues

  Equipment rental revenues increased $6,890,000 or 17.7% from 1994 to 1995 and
$4,873,000 or 10.6% from 1995 to 1996. The acquisition of BERS, completed August
13, 1996, contributed $1,770,000 to the 1996 rental revenue increase. The
remaining $3,103,000 growth in rental revenues reflects an increase of 6.8%.
This rental revenue increase resulted from continued growth at acute care
hospitals and at established offices with substantially higher growth rates
associated with rental revenues from alternate care customers and at newer
offices. The Company expects rental revenue generated from alternate care to
continue to increase reflecting the continuing trend in health care toward
treating the patient in the most cost effective environment.

  Effective February 1, 1997, the Company entered into a two year agreement with
Premier, Inc. (Premier), the nation's largest health care alliance enterprise,
for medical equipment rentals and services. This agreement is expected to
produce significant savings for Premier's 1,750 hospitals and health system
owners and affiliates, as it offers Premier's members special rates, discounts
and incentives on equipment rentals. The Premier agreement and some longer term
commitments the Company has entered into with some of its larger customers have
required some price concessions.

  Sales of supplies and equipment, together with the related costs of these
items, represent primarily disposable medical supplies used in connection with
the Company's rental equipment. The Company believes that supplying these
products is important to its full service business even though the commodity-
like nature of these products results in substantially lower gross margins than
its rental equipment business. During the past 2 years, sales of supplies and
equipment have declined by $1,241,000 from 1994 to 1995 and by $1,030,000 from
1995 to 1996. These decreases primarily reflected a continuing trend by a major
vendor of disposables to market its products directly to some of the Company's
larger customers. Also, in 1996, sales of the DPAP device continued to decline
and, as a result, the Company made a decision to abandon the sleep apnea market.
Sales of DPAP devices were $750,000 in 1995 and $424,000 in 1996. (See "Disposal
of DPAP Inventories" below). The acquisition of BERS contributed $295,000 to
total sales revenue in 1996.

  Other revenues, primarily representing net gains on sales of used rental
equipment, remain insignificant throughout the three year period. The Company
expects that such revenues will continue to be a small portion of total
revenues.

Rental Costs

  Cost of equipment rentals represents the direct costs of operating the
Company's district offices including occupancy, fleet operations, equipment
repairs and technical service costs. These costs as a percentage of rental
revenues increased from 25.7% in 1994 to 25.8% in 1995 and 26.3% in 1996.
Without BERS, the percentage for 1996 was 26.6%. Direct rental expenses
reflected planned expense increases, including expenses associated with several
new Asset Management Partnership Programs signed in 1994, 1995 and 1996 and with
the opening of nine new offices from 1994 through 1996 in addition to the
acquisition of BERS.

                                     D-20
<PAGE>
 
  Rental equipment depreciation as a percentage of rental revenues decreased
from 24.4% in 1994 to 23.5% in 1995. This decrease was the result of increased
rental revenues generated in 1995. Rental equipment depreciation as a percentage
of rental revenues increased to 24.8% in 1996, reflecting a full year's
depreciation on 1995 equipment acquisitions which was not matched by growth in
rental revenues and due to depreciation expense on surplus Bazooka beds (See
"Rental Equipment Build Up" below). Equipment purchases increased from $15.7
million in 1994 to $21.2 million in 1995 but decreased to $12.7 million
(excluding the $4.2 million of equipment acquired in the BERS transaction) in
1996. Rental equipment purchases primarily reflect customer driven demand for
new rental products.

Gross Profit

  Gross margin on rentals represents equipment rental revenues reduced by the
cost of equipment rentals and rental equipment depreciation. Gross margin on
rentals increased from 49.9% in 1994 to 50.6% in 1995 and decreased to 48.9% in
1996. The increase from 1994 to 1995 was due to rental revenues increasing at a
faster rate than rental equipment depreciation. The decrease from 1995 to 1996
was the result of increases in the cost of equipment rentals and rental
equipment depreciation expenses discussed above.

  Sales gross margin as a percentage of sales of supplies and equipment improved
from 18.0% in 1994 to 18.7% and 20.4% in 1995 and 1996, respectively. Without
BERS, the percentage for 1996 was 19.1%. This increased sales gross margin was
due to a vendor selling lower margined products directly to hospitals, which
resulted in a higher margin percentage on a lower volume of total sales and, in
1995, due to the impact of higher margin DPAP sales. In addition, sales gross
margins were further decreased by the disposal of DPAP inventories. (See
"Disposal of DPAP Inventories" below.)

Selling, General and Administrative Expenses

  Selling, general and administrative expenses increased $1,999,000 from 1994 to
1995 and $1,442,000 from 1995 to 1996. The increase from 1994 to 1995 primarily
reflected performance based incentive and profit sharing accruals, planned
personnel related expenses to support the Company's continuing geographic
expansion, and expenses associated with planned growth in the alternate care
market, including a $175,000 increase in bad debt expense to reserve for the
risks associated with increased business with alternate care customers. The
lower increase between 1995 and 1996 reflects a decrease in performance based
incentive and profit sharing expenses. The 1996 increase includes approximately
$800,000 related to BERS selling, general and administrative expenses and BERS
related goodwill amortization and approximately $300,000 related to professional
fees and Directors' compensation incurred in connection with the Board of 
Directors' review of strategic alternatives for enhancing shareholder value.

  As a result of the slower than anticipated rental revenue growth and lower
margins discussed above, the Company instituted expense control initiatives
discussed below.

Deferral of New Office Openings

  In August 1996, the Company announced the deferral of the opening of the
previously announced offices to be located in Oklahoma City, OK and Nashville,
TN.

Expense Control Initiatives

  The Company has implemented several expense control initiatives to reduce or
defer costs. In August 1996, the Company announced executive salary cuts and a
moratorium on new hires. In October, the Company announced the elimination of 10
corporate positions by functional consolidation and cutting nonessential
activities and changed the Company's employee medical benefit program from a
total company-paid plan to a shared-cost program, effective January 1, 1997. The
Company expects the cost reduction in 1997 to be approximately $1 million for
the full year, beginning in the first quarter of 1997. No material costs
relating to these expense control initiatives were incurred in 1996, other than
approximately $100,000 in costs relating to a work force reduction and the
closing of one warehouse facility. However, there can be no assurance that these
programs will result in decreased total expenses or that their implementation
will materially improve margins.

Disposal of DPAP Inventories

  The Company experienced declining sales of DPAP devices during 1996. Because
market acceptance of the DPAP devices did not meet expectations, the Company's
ongoing quarterly assessment resulted in a write-down of $1,030,500 in the
second quarter and a charge of $1,182,545 in the fourth quarter of 1996 to 
write-off the remaining carrying value of DPAP inventory and associated supplies
and demo units. The DPAP devices were disposed of in early 1997.

Interest Expense

  Interest expense increased by $516,000 from 1994 to 1995 and by $734,000 from
1995 to 1996, primarily reflecting, in 1996, interest of approximately $410,000
on the BERS acquisition debt and incremental borrowings associated with capital
equipment additions. The 1995 increase resulted from incremental borrowings
associated with a higher level of customer driven capital spending for additions
to the Company's rental equipment pool and increased short term interest rates,
which affected the Company's revolving credit facility. Average borrowings,
which increased from $16.3 million in 1994 to $21.4 million in 1995 and $30.5
million in 1996, were also affected by the carrying cost of surplus Bazooka
inventories and the DPAP inventory.

Income Taxes

  The Company's effective tax rate decreased from 42.9% in 1994 to 41.5% in 1995
and increased to 49.6% in 1996. The increase in the effective rate in 1996 was
primarily due to the effect of non-deductible expenses on the Company's lower
taxable income.

Net Income

  Net income increased $753,000 from 1994 to 1995, primarily as a result of the
continued trend of quarterly increases in rental revenue, which began in mid
1994. Net income decreased $1,818,000 from 1995 to 1996, primarily as a result
of the disposals of DPAP inventories.

Quarterly Financial Information; Seasonality

  Quarterly operating results are typically affected by seasonal factors.
Historically, the Company's first and fourth quarters are the most profitable,
reflecting increased hospital utilization during the fall and winter months.

Capital Resources and Liquidity

  As an asset intensive service business, the Company requires continued access
to capital to support the acquisition of equipment for rental to its customers.
The Company expects that rental equipment purchases, including purchases with
respect to anticipated new district office openings, will approximate $19.0
million in 1997.

  The Company has financed its equipment purchases primarily through internally
generated funds and unsecured borrowings. As of December 31, 1996, these
unsecured borrowings were comprised of term loans and a $20 million revolving
credit facility available through June 30, 1999. As of December 31, 1996,
approximately $8.7 million of the revolving credit facility was unused. Net cash
flows from operating activities were $14.7 million, $13.1 million and $11.5
million for the years ended December 31, 1996, 1995 and 1994, respectively.

  The Company believes that net cash flow from operating activities and use of
its existing credit facility will be sufficient to fund working capital and
capital expenditure needs for the foreseeable future. Assuming debt financing
continues to be available at reasonable rates, the Company anticipates
maintaining a ratio of long-term debt to total capitalization in the range of
40% to 60%. Such ratio was 56.1% as of December 31, 1996.

  The Company does not maintain cash balances at its principal bank under a
Company policy whereby the net of collected balances and cleared checks is, at
the Company's option, applied to or drawn from the credit facility on a daily
basis. At December 31, 1996, BERS held $197,000 of cash in an account which will
be closed in 1997.

Completed Acquisition

  On August 13, 1996, the Company completed its acquisition of Biomedical
Equipment Rental and Sales, Inc. (BERS) pursuant to a stock purchase agreement
among the Company and the shareholders of BERS. As a result of the acquisition,
the Company acquired all of the outstanding capital stock of BERS, and BERS
became a wholly owned subsidiary of the Company. In connection with the
acquisition, the Company paid approximately $10,700,000 to the shareholders of
BERS and repaid approximately $1,650,000 of outstanding indebtedness of BERS.
BERS results are included in the financial statements only from the date of
acquisition.

Industry Assessment

  The Company's customers, primarily acute care hospitals and other health care
providers, have been and continue to be faced with cost containment pressures
and uncertainties with respect to health care reform. The Company believes that,
although specific legislation has not been enacted, reform has begun with
movement toward health care related consolidations, managed care and the
formation of integrated healthcare systems. There appears to be an effort by
providers of health care to coordinate all aspects of patient care irrespective
of delivery location. Likely changes in reimbursement methodology, and a gradual
transition toward fixed, per-capita payment systems and other risk-sharing
mechanisms will reward health care providers who improve efficiencies and
effectively manage their costs, while providing care in the most appropriate
setting. Although future reimbursement policies remain uncertain and
unpredictable, the Company believes that the current reform efforts will
continue to focus on cost containment in health care, with universal access to
care and quality of care being important, but nonetheless secondary
considerations.

  The Company believes its Pay-Per-Use Equipment Management Programs respond
favorably to the current reform efforts by providing high quality equipment
through programs which help health care providers improve their efficiency while
effectively matching costs to patient needs, wherever that care is being
provided. While the Company's strategic focus appears consistent with the
providers' efforts to contain costs and improve efficiencies, there can be no
assurances as to how health care reform will ultimately evolve and the impact it
will have on the Company.

  Because the capital equipment procurement decisions of health care providers
are significantly influenced by the regulatory and political environment for
health care, historically the Company has experienced certain adverse operating
trends in periods when significant health care reform initiatives were under
consideration and uncertainty remained as to their likely outcome. To the extent
general cost containment pressures or health care spending and reimbursement
reform, or uncertainty as to possible reform, causes hospitals and other health
care providers to defer the procurement of medical equipment, reduce their
capital expenditures or change significantly their utilization of medical
equipment, the Company's results of operations could be adversely affected.

Pending Sale of the Company

  On February 10, 1997, the Company and MEDIQ Incorporated entered into a
definitive agreement for MEDIQ to acquire UHS for $17.50 per UHS share.
Including the assumption of the Company's debt, the total purchase price is
approximately $138,000,000. The transaction is structured as a cash merger that
is expected to close in late March or early April, 1997 and is subject to
approval by a majority of UHS's shareholders and Hart-Scott-Rodino clearance.

Rental Equipment Build Up

  The Company acquired its equipment pool of Bazooka portable specialty beds
under an exclusive agreement which was terminated in March 1996. The Company
does not expect to acquire any additional Bazooka beds. Utilization of Bazooka
beds in the Company's pool is currently below the desired level, resulting in a
temporary product imbalance (approximately $2,816,000 of excess equipment at
December 31, 1996 versus approximately $2,471,000 at December 31, 1995). The
Company has performed an impairment analysis based upon projected income and
cash flows in accordance with current accounting literature and has determined
that these assets are currently fully recoverable. The Company believes this
supply/demand imbalance will be reduced. However, in the event that anticipated
growth in customer demand for this product does not occur, the Company's margin
on the products could be adversely affected.

                       ITEM 11.  EXECUTIVE COMPENSATION
                       --------------------------------

Report of Compensation Committee on Executive Compensation

     Under rules established by the Securities and Exchange Commission, the
Company is required to provide certain data and information in regard to the
compensation and benefits provided to the Company's Chief Executive Officer and
its other executive officers. The disclosure requirements for these individuals
(the "executive officers") include the use of tables and a report explaining the
rationale and considerations that led to fundamental executive compensation
decisions affecting those individuals. In fulfillment of the report requirement,
the Compensation Committee of the Board of Directors (the "Committee"), at the
direction of the Board of Directors, has prepared the following report for
inclusion in this Form 10-K.

     Overview

     The Committee is responsible for establishing and making certain
recommendations to the Board of Directors concerning executive compensation,
including annual base salaries, bonuses, stock options, long-term incentives and
other benefits. The Committee is composed entirely of independent outside
directors of the Company. The Committee annually reviews and evaluates the
Company's corporate performance, compensation levels and equity ownership of its
executive officers.

     The Company's executive compensation policies and programs have been
developed and refined over the past several years. In late 1993, the Committee
and the full Board extensively reviewed the Company's existing executive
compensation and approved additional compensation programs and plans for the
Company's executive officers commencing January 1994. The Committee, with the
aid of an independent consulting firm, sought to bring the Company's executive
compensation in line with comparable companies and to have an appropriate
portion of executive compensation tied to the long-term performance of the
Company. Overall, the outcome of the Committee's review was to establish new
performance-based incentive compensation and to tie a greater proportion of
total compensation to Company performance.

     The executive compensation philosophy of the Company is intended to (1)
compensate executive officers in a manner that reinforces the executive
officer's commitment to long-term service with the Company and provides
compensation comparable to other similarly situated companies, thus allowing the
Company to retain talented executives who are critical to the Company's long-
term success; and (2) support a pay for performance policy that motivates
executive officers to achieve overall corporate goals and awards individual
executive officers with compensation based on short- and long-term individual
and corporate performance. In particular, the Company's executive compensation
program provides for a portion of executive compensation to be fixed, maintains
relative equity among executives, offers modest annual cash incentives based on
Company performance and certain subjective factors and offers significant cash
and equity incentives tied to the Company's long-term performance.

     Executive Compensation Program

     The components of the Company's executive compensation program which are
subject to the discretion of the Committee on an individual basis include cash-
and equity-based compensation. Specifically, these components consist of (1)
base salaries, (2) annual performance-based cash incentives (bonuses), (3) stock
options and (4) long-term performance-based cash incentives. The ultimate
composition of executive compensation reflects the Company's goals of attracting
and retaining highly qualified personnel and supporting a performance-oriented
environment that rewards both corporate and personal performance over the long
term. Most of the executive officers have been with the Company in excess of ten
years, and, together, the executive officers hold a significant portion of the
Common Stock.  These factors have caused the Committee to focus more on the need
to retain its current executive officers, rather than attracting new executives,
and to foster continuing loyalty to the Company within the executive officer
group.

                                     D-27

<PAGE>
 
     Base Salary. Annual base salaries are established as a result of the
Committee's analysis of each executive officer's individual performance during
the prior year, the overall performance of the Company during the prior year and
historical compensation levels within the executive officer group. Generally,
the Committee seeks to set base salaries at a level which is above the average
for companies of comparable revenues and growth history. At the beginning of
1996, base salaries for the year were set to reflect modest merit increases
(4.3%) from the prior year. Subsequently, the executive officers voluntarily
agreed to a salary reduction effective August 1, 1996. Mr. Minner, as President,
agreed to a 15% reduction in salary and the Vice Presidents agreed to a 10%
reduction in salary.

     Bonuses. Beginning in fiscal 1994, the Company's executive officers were
eligible for annual cash bonuses under the Company's Annual Incentive Plan (the
"AIP"). The AIP provides the opportunity for executives to earn annual cash
bonuses based on the achievement of predetermined financial objectives. Targeted
bonus amounts are 30% of annual base salary for the Chief Executive Officer and
20% of annual base salary for all other executive officers. All, none or a
portion of these targeted bonus amounts may be paid, based upon the achievement
of three equally-weighted performance goals and application of a formula which
adjusts the targeted bonus amount relative to such achievement. Two of these
performance goals are financial goals approved annually by the Committee and the
Board of Directors and include a pre-tax income objective and a rental revenue
objective. The third performance goal is subjective, permitting the Committee to
acknowledge achievement of individual and Company goals that are nonfinancial in
nature. If certain threshold levels of the specified financial objectives are
not met, none of the applicable portion of the targeted bonus will be paid. In
the event the Company fails to have positive net income for any year, no bonuses
will be paid under the AIP for that year. In addition, to the extent performance
goals are exceeded, targeted bonus amounts may be increased by up to 50%. Thus,
under the AIP, the maximum annual bonus opportunity is 45% of annual base salary
for the Chief Executive Officer and 30% of annual base salary for all other
executive officers.

     In 1996, threshold levels of the specified financial objectives were not
achieved, and accordingly no bonuses were awarded based on these two performance
goals. Bonuses to the named executive officers under the AIP for 1996, as set
forth in the "Summary Compensation Table" below, reflect the Committee's belief
that the Company had achieved significant nonfinancial objectives, and such
bonuses were equal to one-half of the targeted nonfinancial bonus amount.

     Stock Options. The Company's 1992 Long-Term Incentive and Stock Option Plan
(the "Stock Option Plan") is designed to align a portion of executive and other
senior employee compensation with the long-term interests of shareholders. The
Stock Option Plan permits the granting of several different types of stock-based
awards to a broad range of employees. To date, only stock options have been
awarded. Generally, the Committee will not grant options to purchase more than
100,000 shares of Common Stock in the aggregate in any one year. The stock
options give the holder the right to purchase shares of UHS Common Stock over a
ten-year period at the fair market value per share as of the date the option is
granted.

     Long-Term Cash Incentives. Beginning in fiscal 1994, each of the Company's
executive officers received awards under the Company's Long-Term Incentive Plan
(the "LTIP"). Under the LTIP, awards are made to the Company's executive
officers on an annual basis. Each award represents a targeted cash amount that
may be earned by the executive at the end of a three-year period in the event
that specified, cumulative pre-tax income and rental revenue objectives approved
by the Board of Directors and the Committee are achieved during such period. The
pre-tax income objective and the rental revenue objective are weighted equally
in determining whether all, none or a portion of the award will be paid, such
that, if the targeted rental revenue objective is achieved over the three year
period, but the targeted pre-tax income objective is not, the executive is
entitled to be paid one-half of the applicable award amount. Payouts under the
LTIP are targeted at 60% of annual base salary for the Chief Executive Officer
and 30% of annual base salary for all other executive officers. LTIP award
recipients may receive a portion of the targeted payout amount if certain
threshold levels of each of the specified objectives are met. If these
thresholds are not met, none of the applicable portion of the targeted payout
will be made. In addition, to the extent performance goals are exceeded,
targeted bonus amounts may be increased. In addition to annual grants in each of
1994, 1995 and 1996, executive officers received a one-time award upon adoption
of the LTIP.

Compensation of Chief Executive Officer

     The Company's Chief Executive Officer is compensated generally in
accordance with the criteria discussed above relating to the executive
compensation program. Compensation for the Chief Executive Officer consists of
the following components: (1) base salary, (2) an annual performance-based cash
bonus, (3) stock options and (4) long-term performance-based cash incentives.
Mr. Minner's base salary is established as a result of the Committee's analysis
of the Chief Executive Officer's individual performance during the prior year,
the overall performance of the Company during the prior year and historical
compensation levels at the chief executive officer level.

     At the beginning of 1996, Mr. Minner's base salary for 1996 reflected a
4.3% merit increase over his 1995 base salary. Subsequently, Mr. Minner agreed
to a 15% reduction in salary, effective August 1, 1996. Mr. Minner's 1996 bonus
was determined in accordance with the AIP described above. Although the
Committee considered many factors, the following indicia of personal performance
were particularly important to the Company in determining the amount of Mr.
Minner's salary and the discretionary portion of his bonus: (1) the continuing
growth of the Company despite increased uncertainty in the health care industry,
and (2) the ability of the Company to exceed or meet the level of performance of
its competitors.

     Mr. Minner's long-term incentive compensation (stock option grants and LTIP
awards) was consistent with the prior year and was intended to provide a
significant and appropriate tie between overall compensation and the performance
of the Company over the long term. Based on information gathered for the
Committee by the independent consulting firm in late 1993, the Committee
believes that such long-term incentives are comparable to those provided to
chief executives by companies of similar revenue size and growth history.

     Section 162(m)

     The Company, with the approval of shareholders at the 1994 annual meeting,
amended the Stock Option Plan in order to comply with the proposed guidelines
under Section 162(m) of the Internal Revenue Code of 1986, as amended, relating
to the deductibility of compensation paid to executive officers named in the
"Summary Compensation Table." As a result of this amendment, the Committee
believes that option grants will be considered "qualified performance-based
compensation" not subject to the limitation imposed by such Section. The
Committee does not believe that annual compensation to any of the named
executive officers for purposes of Section 162(m) will exceed $1 million in
fiscal 1997 or for the foreseeable future. The Committee will continue to
monitor this matter and may propose additional changes to the executive
compensation program if warranted.

Director Compensation

     Members of the Board of Directors who are not employees of the Company
receive payments of $14,400 per year and $1,000 per meeting attended for their
services, and all directors are reimbursed for expenses actually incurred in
attending meetings of the Board of Directors and its committees. In connection
with their services on a Special Committee, established by the Board of
Directors to carry out the process of exploring alternatives to enhance
shareholder value ("Special Committee"), Mr. Humphries, Mr. McGrath and Ms.
Bohn, the non-employee directors, received in 1996 through February 1997,
$25,000, $15,000 and $15,000, respectively, plus $1000 for each of the nine
Special Committee meetings attended. Directors employed by the Company receive
no directors' fees.

     In addition, non-employee directors are eligible to participate in the
Company's 1992 Directors' Stock Option Plan, as amended (the "Directors' Plan").
Eligible directors are automatically granted an option to purchase 4,000 shares
of Common Stock (an "Initial Grant") on the date they first became a director,
and such options are exercisable six months following the date of grant. On the
date of each annual meeting of shareholders, each eligible director receives an
additional option grant of 2,500 shares of Common Stock which first becomes
exercisable six months after the date of grant. The exercise price of an option
granted under the Directors' Plan is the fair market value (based on the Nasdaq
Stock Market closing price) of the Common Stock on the date the option is
granted. Options to purchase an aggregate of 37,000 shares have been
automatically granted to Mr. Humphries, Mr. McGrath and Ms. Bohn.

Compensation Committee Interlocks and Insider Participation; Certain
Relationships

     Ms. Bohn, a director of UHS and member of the Compensation Committee in
1996, is a Managing Director of Piper Jaffray, Inc. ("Piper Jaffray"), and Chief
Administrative Officer of Piper Jaffray Companies, Inc., the parent of Piper
Jaffray. Piper Jaffray has provided from time to time financial advisory
services for the Company. In November 1996, the Company engaged Piper Jaffray to
assist in analyzing its strategic alternatives to enhance shareholder value. In
February 1997, Piper Jaffray, pursuant to an engagement letter dated January 3,
1997, provided the Company with a financial opinion as to the fairness, from a
financial point of view, to the shareholders of a proposed merger with and into
MEDIQ Incorporated, a Delaware corporation. Ms. Bohn has not been and is not
expected to be directly involved in the provision of any such services.

Employment Contracts and Change in Control Arrangements

     None of the Company's executive officers currently has a written employment
agreement.

     Effective January 1994, the Company adopted the Top Management Change-in-
Control Severance Plan (the "Severance Plan"). The Severance Plan is designed to
encourage continuity of management in the event of a change of control of the
Company. Under the Severance Plan, each of the Company's executive officers is
eligible to receive a severance payment up to three times his base salary in the
event of a change of control of the Company and termination of such officer
within three years of such change in control for reasons other than death, total
disability or "just cause" and voluntary termination without "good reason" (all
as defined in the Severance Plan). The Severance Plan defines a "change of
control" to occur upon (1) an acquisition by any person of 20% or more of the
Company's combined voting power, if the Board of Directors declares such
acquisition to be a "change in control", (2) an acquisition by any person of 40%
or more of the Company's combined voting power, (3) a majority of directors are
persons other than persons nominated or appointed by the Board of Directors, (4)
a sale of more than 50% of the assets of the Company or the Merger of the
Company into another company or (5) a vote of a majority of the directors that a
change of control will occur and such a change in control does occur within six
months thereafter.

     The Company has certain other compensatory arrangements with its executive
officers which will result from a change in control of the Company. To the
extent not already exercisable, options granted to the named executive officers
under the Stock Option Plan generally become exercisable in the event of a
merger in which the Company is not the surviving corporation, a transfer of all
of the Company's stock, a sale of substantially all of the Company's assets or a
dissolution or liquidation of the Company, unless the successor corporation
assumes the outstanding options or substitutes substantially equivalent options.
In addition, under the supplemental pension plan discussed below, the named
executive officers are entitled to receive a lump sum payment equal to the
present value of all benefits accrued under such plan upon any qualifying
termination of such executive officer's employment (as defined under the
Severance Plan) within thirty-six months of a change of control (as defined
under the Severance Plan). In the event of such a change in control, named
executive officers are also entitled to payment of a pro rata portion of all
awards granted under the LTIP based on achievement of performance objectives
during that portion of the performance period elapsed prior to the change in
control.

31, 1996 to the Chief Executive Officer and the executive officers named in the
"Summary Compensation Table" above, and the values of the options held by such
persons at December 31, 1996.  No options held by named executive officers were

(1)  Each option represents the right to purchase one share of Common Stock. The
     stock option grants shown in this column were all made on January 19, 1996
     pursuant to the Stock Option Plan, and will become exercisable with respect
     to one-third of the shares subject to the option on July 19, 1997, 1998 and
     1999.

(2)  The exercise price is equal to the market price on the date of grant with
     respect to each option. The exercise price may be paid in cash, in shares
     of Common Stock with a market value as of the date of exercise equal to the
     option price or a combination of cash and shares of Common Stock.

(3)  The compounding assumes a ten-year exercise period for all option grants.
     These amounts represent certain assumed rates of appreciation only. Actual
     gains, if any, or stock option exercises are dependent on the future
     performance of the underlying Common Stock, and overall stock market
     conditions. The amounts reflected in this table may not necessarily be
     achieved. If the price of the Common Stock at the date of grant ($9.37)
     were to appreciate at 5% and 10%, respectively, compounded annually for ten
     years (the term of the option), then the Common Stock would have a closing
     price on January 19, 2006 of approximately $15.26 and $24.30 per share,
     respectively (assuming no change in the number of outstanding shares of UHS
     Common Stock).

Incentive Plan (the "LTIP") described above during the fiscal year ended
December 31, 1996 to the Chief Executive Officer and the executive officers
named in the Summary Compensation Table above. Any payments earned and made
under the LTIP will be reported in the Summary Compensation Table in the year
paid. The amounts shown in the table are for illustration purposes only and
should not be construed as payouts for the executives listed. Performance
thresholds must be achieved before any payments are made under the LTIP.

(1)  Each unit represents one dollar of a targeted cash payment to be made upon
     achievement of certain cumulative performance goals over a three-year
     period. Performance goals are based on target levels of pre-tax income and
     rental revenues, and the payouts are adjusted pursuant to a formula which
     adjusts for performance against the target goals.

(2)  Each performance period is a three-year period ending on the date
     indicated. Payouts, if any, will be made shortly after receipt of audited
     financial statements for the applicable period, provided that a pro rata
     portion of such payouts may be made earlier upon a "change in control" as
     described above under "Employment Contracts and Change in Control
     Arrangements."

(3)  Unless a threshold level of either or both of the cumulative performance
     goals are achieved, there will be no payouts at the end of the performance
     period.

      A participant's remuneration covered by the Pension Plans is his or her
average salary (as reported in the Summary Compensation Table) for the five
consecutive plan years in which the employee received his or her highest average
compensation. The table does not reflect certain limitations on annual benefits
payable imposed by the Internal Revenue Code, because the Company's non-
qualified supplemental pension plan provides for the payment of additional
benefits so that retiring employees may receive, in the aggregate, the benefits
they would have been entitled to receive had such limitations not been imposed.
As of December 31, 1996, Messrs. Minner, Bohman, Larsen, Dovenberg and Wenell
had 27.0, 23.5, 21.3, 8.7 and 25.0 years of credited service, respectively,
under the Pension Plans.

Certain Relationships and Related Transactions

      Ms. Bohn, a director of UHS and member of the Compensation Committee in
1996, is a Managing Director of Piper Jaffray, Inc. ("Piper Jaffray"), and Chief
Administrative Officer of Piper Jaffray Companies, Inc., the parent of Piper
Jaffray.  Piper Jaffray has provided from time to time financial advisory
services for the Company.  In November 1996, the Company engaged Piper Jaffray
to assist in analyzing its strategic alternatives to enhance shareholder value.
In February 1997, Piper Jaffray, pursuant to an engagement letter dated January
3, 1997, provided the Company with a financial opinion as to the fairness, from
a financial point of view, to the shareholders of the proposed MEDIQ merger (the
"Piper Jaffray Opinion"). Ms. Bohn has not been and is not expected to be
directly involved in the provision of any such services.

      For acting as financial advisor, UHS has agreed to pay Piper Jaffray (i) a
fee of $125,000 due under the initial engagement letter dated November 7, 1996;
(ii) $275,000 in cash upon Piper Jaffray rendering the Piper Jaffray Opinion;
(iii) $25,000 in cash upon Piper Jaffray rendering an update to the Piper
Jaffray Opinion at the time of mailing of a proxy statement relating to the
merger to the UHS shareholders; and (iv) in the event a sale or merger of UHS,
including the proposed merger with MEDIQ, is consummated pursuant to an
agreement or commitment which is entered into before January 3, 2000, a success
fee payable in cash equal to 1.8% of the consideration paid in such transaction
for the equity of UHS, including options, less the fees paid under (i), (ii) and
(iii) above.  To date, Piper Jaffray has been paid an aggregate of $400,000 of
fees pursuant to the engagement letter.  Whether or not the proposed merger with
MEDIQ is consummated, UHS has also agreed to reimburse Piper Jaffray for its
reasonable out-of-pocket expenses and to indemnify it against certain
liabilities relating to or arising out of services performed by Piper Jaffray as
financial advisor to UHS.

Report of Independent Accountants



To the Board of Directors and Shareholders of
Universal Hospital Services, Inc. and Subsidiary:

We have audited the accompanying consolidated balance sheets of Universal
Hospital Services, Inc. and Subsidiary as of December 31, 1996 and 1995, and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the three years in the period ended December 31, 1996. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Universal Hospital Services, Inc. and Subsidiary as of December 31, 1996 and
1995, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996 in conformity with
generally accepted accounting principles.

Universal Hospital Services, Inc. and Subsidiary 
Notes to Consolidated Financial Statements 
 
1.   Description of Business:
      
     Universal Hospital Services, Inc. (the Company or UHS) is a leading
     provider of movable medical equipment, service programs and products to
     healthcare providers in both the acute and alternate care markets. The
     consolidated financial statements include the accounts of the Company and
     its wholly owned subsidiary, Biomedical Equipment Rental and Sales
     Incorporated (BERS) since August 1996 (see Note 4). Through a national
     network of UHS district offices, providers have access to the Company's
     pool of medical devices through the unique Pay-Per-Use/TM/ equipment
     management program. This program charges customers only when equipment is
     in use on a patient, and is supported by a full range of services including
     delivery, training, technical and educational support, inspection and
     maintenance. The Company also sells medical products not used in its rental
     pool and disposable medical products used in conjunction with the medical
     equipment it rents.

2.   Pending Sale of the Company:

     On February 10, 1997, the Company and MEDIQ Incorporated (MEDIQ) entered
     into a definitive agreement for MEDIQ to acquire 100% of UHS outstanding
     common stock for $17.50 per share. Including the assumption of the
     Company's debt, the total purchase price is expected to be approximately
     $138,000,000. The transaction is to be structured as a cash merger that is
     expected to close in late March or early April 1997, subject to approval by
     a majority of the Company's shareholders and regulatory clearances.
     
3.   Significant Accounting Policies:
   
     Basis of Consolidation:

     The accompanying consolidated financial statements include the accounts of
     the Company and its wholly owned subsidiary. All significant intercompany
     accounts and transactions have been eliminated in consolidation.

     Inventories:

     Inventories consist of supplies and equipment held for resale and are
     valued at the lower of cost (first-in, first-out method) or market.

     Rental Equipment:

     Depreciation of rental equipment is provided on the straight-line method
     over the equipments' estimated useful lives of five to seven years. The
     cost and accumulated depreciation of rental equipment, retired or sold, is
     eliminated from their respective accounts and the resulting gain or loss is
     recorded in income.

3.   Significant Accounting Policies, continued:

     Property and Office Equipment:

     Property and office equipment includes land, buildings, leasehold
     improvements and shop and office equipment.

     Depreciation of property and office equipment is provided on the straight-
     line method over estimated useful lives of thirty years for buildings,
     remaining lease term for leasehold improvements, and three to ten years for
     shop and office equipment. The cost and accumulated depreciation of
     property and equipment, retired or sold, is eliminated from their
     respective accounts and the resulting gain or loss is recorded in income.

     Cash and Cash Equivalents:

     The Company considers all highly liquid investments purchased with an
     initial maturity of three months or less to be cash equivalents. The
     Company's cash and cash equivalents are deposited with two financial
     institutions.

     Goodwill:
 
     Goodwill represents the excess purchase cost of acquired assets over the
     tangible and identifiable intangible assets' estimated fair market values
     at the date of acquisition and is being amortized on a straight-line basis
     over 15 to 40 years. Accumulated amortization was $2,646,315 and $2,168,203
     as of December 31, 1996 and 1995, respectively.

     Long-Lived Assets:

     Effective January 1, 1996, the Company adopted Statement of Financial
     Accounting Standard (SFAS) No. 121 "Accounting for the Impairment of Long-
     Lived Assets and for Long-Lived Assets to be Disposed of". The adoption of
     SFAS No. 121 did not have a significant impact on the Company's financial
     position or results of operations.

     The Company periodically assesses the recoverability of long-lived assets
     principally rental equipment and goodwill based on projected income and
     related cash flows on an undiscounted basis.

     Revenues:

     Equipment is generally rented on a short-term basis and rentals are
     recorded in income as earned. Supply and equipment sales are recorded at
     the time of shipment.

     Income Taxes:

     Deferred income taxes are computed using the asset and liability method,
     such that deferred tax assets and liabilities are recognized for the
     expected future tax consequences of temporary differences between financial
     reporting amounts and the tax bases of existing assets and liabilities
     based on currently enacted tax laws and tax rates.

     Earnings Per Share of Common Stock:

     Earnings per share of common stock is calculated by dividing net income by
     the weighted average common and common equivalent shares outstanding during
     the year. Common equivalent shares include the dilutive effect of stock
     options.

3.   Significant Accounting Policies, continued:

     Use of Estimates:

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates. The most significant management estimates relate to the
     determination of the allowance for uncollectible accounts receivable and
     obsolete inventories, estimation of the useful lives of rental equipment
     for computing depreciation, assessment of the recoverability of long-lived
     assets, self-insured medical reserves and determination of pension plan
     actuarial assumptions.
 
4.   Acquisition of Biomedical Equipment Rental and Sales, Inc. (BERS):

     On August 13, 1996, the Company acquired BERS pursuant to a Stock Purchase
     Agreement among the Company and the shareholders of BERS. Pursuant to the
     agreement, the Company acquired all of the outstanding capital stock of
     BERS for approximately $10.7 million and repayment of approximately $1.6
     million of outstanding indebtedness of BERS. The acquisition was accounted
     for using the purchase method. Accordingly, the purchase price was
     allocated to assets and liabilities acquired based on their estimated fair
     values. This treatment resulted in approximately $7.3 million of cost in
     excess of net tangible assets acquired (goodwill), which is being amortized
     on a straight-line basis over 15 years. The estimated fair values of assets
     and liabilities acquired are as follows:

5.   Disposal of DPAP Inventories:

     The Company experienced declining sales of Demand Positive Airway Pressure
     (DPAP) devices during 1996. Because market acceptance of the DPAP devices
     did not meet expectations, the Company's ongoing quarterly assessments
     resulted in a write-down of $1,030,500 in the second quarter and a charge
     of $1,182,545 in the fourth quarter of 1996 to write-off the remaining
     carrying value of DPAP inventory and associated supplies and demo units.
     The DPAP devices were disposed of in early 1997.



6.   Book Overdrafts:

     The Company does not maintain cash balances at its principal bank under a
     policy whereby the net of collected balances and cleared checks is, at the
     Company's option, applied to or drawn from the revolving credit facility on
     a daily basis. At December 31, 1996 and 1995, the Company had book
     overdrafts of $858,364 and $1,124,577, respectively.

8.   Long-Term Debt, continued:

     Under the revolving credit agreement with a bank, the Company may borrow up
     to $20,000,000 with a maturity date of June 30, 1999. Borrowings bear
     interest at a rate of between 1.50% and 2.25% per annum over the bank's
     Reserve Adjusted Certificate of Deposit Rate (RACD) as defined in the
     agreement. At December 31, 1996, the Company's interest rate was 7.60%,
     based on the bank's RACD of 5.60%.

     The fair value of long-term debt, based on discounted cash flow analysis
     using current market interest rates for the same or similar issues of debt
     as of December 31, 1996 would be approximately $38,500,000.

     At December 31, 1996, aggregate long-term repayment requirements are as
     follows:

<TABLE>

     The long-term debt agreements restrict dividend payments in excess of
     approximately $1,700,000, and stock repurchases require, among other
     things, that the Company maintain certain working capital and other
     financial ratios.

9.   Commitments and Contingencies:

     Rental expenses were approximately $3,500,000, $3,300,000 and $2,600,000
     for the years ended December 31, 1996, 1995 and 1994, respectively. The
     Company is committed under various noncancellable operating leases for
     regional sales and service offices and vehicles with minimum annual rental
     commitments of approximately the following:

     The Company in the ordinary course of business could be subject to
     liability claims related to the equipment that it rents and services. The
     Company believes that its liability insurance is adequate to meet any
     present or future liability claims.

10.  Employee Benefit Plans:

     The Company sponsors a noncontributory defined benefit pension plan that
     covers substantially all of its employees. Plan benefits are to be paid to
     eligible employees at retirement based primarily on years of credited
     service and on participants' compensation. Plan assets consist primarily
     of U.S. Government securities and common stocks.

     Pension expense, in thousands, for the years ended December 31, included
     the following components:

10.  Employee Benefit Plans, continued:

     Effective January 1, 1994, the Company adopted a supplemental executive
     retirement plan (SERP) designed to make up the shortfall in retirement
     benefits caused by limitations specified by the Omnibus Budget
     Reconciliation Act of 1993. This plan provides supplemental pension
     benefits to the executive officers of the Company in addition to the
     amounts received under the Company's defined benefit plan described above.
     This combination of benefits is equivalent to those benefits which would
     have been paid under the Company's qualified defined benefit pension plan
     without regard to the Internal Revenue Service statutory limitation on
     qualifying wages. Such benefits will be paid from the Company's assets. The
     unfunded accumulated benefit obligation under the plan at December 31, 1996
     and 1995 was $315,000 and $248,000, respectively. The projected benefit
     obligation under the plan at December 31, 1996 and 1995 was $1,057,000 and
     $1,185,000, respectively. Assumptions used to calculate the benefit
     obligations were consistent with the Company's defined benefit pension
     plan, except that projected compensation increases were assumed to be 5.5%
     in 1996 and 1995. The pension expense for the years ended December 31,
     1996, 1995 and 1994 related to this plan was $44,000, $138,000 and $132,000
     respectively.

     The Company also sponsors a defined contribution plan, which qualifies
     under Section 401(a) of the Internal Revenue Code and covers substantially
     all of the Company's employees. Employees contribute up to 6% of their
     earnings as a thrift contribution, subject to IRS limitations, and up to
     10% as a voluntary contribution. The Company matches 50% of employee thrift
     contributions. The Plan was amended and restated on December 6, 1994 to add
     a 401(k) provision that allows employees to contribute annually up to 6% of
     their base compensation before tax, subject to IRS limitations, and up to
     6% as an after-tax contribution. Under the amended and restated plan, the
     Company matches 50% of the first 6% of base compensation that a participant
     contributes to the Plan. The effective date of the 401(k) provision was
     July 1, 1995. For the years ended December 31, 1996, 1995 and 1994,
     approximately $279,000, $234,000 and $211,000, respectively, was expensed
     as contributions to the plan.

     The Company is self-insured for employee health care costs. The Company is
     liable for claims up to $83,250 per family per plan year and aggregate
     claims up to 125% of expected claims per plan year. Self-insurance costs
     are accrued based upon the aggregate of the liability for reported claims
     and an actuarially determined estimated liability for claims incurred but
     not reported.

</TABLE> 

     The Company has not recorded a valuation allowance as of December 31, 1996
     and 1995 related to the deferred tax assets, as management believes the
     future reversing taxable temporary differences will be sufficient to
     recover the total deferred tax asset.

12.  Shareholders' Equity:

     Each outstanding share of common stock is entitled to one vote.

     In December 1995, each share of the Class B common stock was converted to
     one share of common stock through a secondary offering. No proceeds of the
     offering were received by the Company.

     In December 1994, the Board of Directors authorized a stock repurchase
     program under which up to 500,000 shares of the Company's common stock
     could have been repurchased. Such purchases could have been made at
     prevailing prices on the open market, by block purchase or in private
     transactions at any time until June 30, 1996. A total of 45,000 shares have
     been purchased in the open market pursuant to these authorizations. In July
     1996, an additional 300,000 shares were authorized by the Board of
     Directors for repurchase. Such purchases can be made at any time until June
     30, 1997. A total 103,000 have been purchased pursuant to these
     authorizations.

12.  Shareholders' Equity, continued:

     In November 1996 the Company adopted a shareholder rights plan under which
     rights to purchase shares of a new series of preferred stock have been
     declared as a dividend at the rate of one right for each share of common
     stock held by shareholders of record at the close of business on November
     21, 1996. Each right under the shareholder rights plan will entitle the
     holder to buy one 1/100th of a share of a new series of junior preferred
     stock at a price of $40. The rights will be exercisable only if a person or
     group acquires or makes a tender offer for 15% or more of the Company's
     outstanding common stock (except in connection with an offer permitted by
     the Board of Directors and other limited exceptions). The rights are
     redeemable at 1/10th of a cent per right at any time prior to the
     acquisition of a 15% position. The acquisition described in Note 2 is
     expected to meet the criteria of a permitted offer. As such, the rights
     will expire upon closing of the agreement.

     If a person or group acquires 15% or more of the Company's common stock
     (except in connection with a permitted offer), each right will entitle its
     holder to purchase, at the right's then-current exercise price, the
     Company's common stock having a market value of twice the right's exercise
     price. If the Company is acquired in a merger or sells 50% or more of its
     assets or earning power, each right will entitle its holder to purchase, at
     the right's then-current exercise price, the acquiring Company's common
     stock having a market value of twice the right's exercise price.

13.  Stock Option and Stock Purchase Plans:

     During 1992 and as amended in 1994, the Company adopted a Long-Term
     Incentive and Stock Option Plan, a Director's Stock Option Plan and an
     Employee Stock Purchase Plan. Under the Long-Term Incentive and Stock
     Option Plan (Incentive and Stock Option Plan), the Company may grant
     incentive stock options, stock options and performance awards to the
     Company's employees. A total of 600,000 shares of common stock are reserved
     for issuance under the Incentive and Stock Option Plan. The Incentive and
     Stock Option Plan expires in 2002. These options become exercisable in
     increments over a 3-1/2 year period, expiring 10 years after the grant
     date.

     The Director's Stock Option Plan (Director Plan) covers nonemployee
     directors. Options may be granted annually to eligible directors. Under the
     Director Plan, the Company has reserved 75,000 shares of common stock for
     issuance. Options under the Director Plan become exercisable six months
     subsequent to date of grant, expiring five years after the grant date.

     All options were granted at fair market value at date of grant.

Stock options outstanding at December 31, 1996 for the Incentive and Stock
Option Plan and Director Plan had a range of exercise prices of $5.38 to $9.38
and $6.00 and $8.75, respectively, and an average remaining life of 6.56 and
2.48 years, respectively.

Under the Employee Stock Purchase Plan, an eligible employee may purchase shares
of common stock from the Company through payroll deductions of up to 10% of
their base compensation at a price share equal to 85% of the lesser of the fair
market value of the Company's common stock as of the first or last day of each
six-month offering period. A total of 225,000 shares are reserved for issuance
under this plan. During 1996 and 1995, respectively, 57,979 and 33,311 shares
were purchased by employees under this plan, leaving 37,147 available for
purchase at December 31, 1996.

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, a new standard of accounting and
reporting for stock-based compensation plans. The Company has adopted the new
standard in 1996. The Company has continued to measure compensation cost for its
incentive and stock option plan, director plan and employee stock purchase plan,
using the intrinsic value method of accounting it has historically used and,
therefore, the new standard has no effect on the Company's operating results.

13.  Stock Option and Stock Purchase Plans, continued:

     Had the Company used the fair value-based method of accounting for its
     incentive and stock option plan, director plan and employee stock purchase
     plan beginning in 1995 and charged compensation cost against income, over
     the vesting period, based on the fair value of options at the date of
     grant, net income and net income per share for the years ended December 31,
     1996 and 1995 would have been reduced to the following pro forma amounts:

</TABLE> 

     The weighted-average grant-date fair value of options granted during 1996
     and 1995 was $5.28 and $4.13, respectively. The weighted-average grant-date
     fair value of options was determined separately for each grant under the
     Company's various plans by using the fair value of each option grant on the
     date of grant, utilizing the Black-Scholes option-pricing model and the
     following key assumptions:
