ITEM 5.   OTHER EVENTS.


          Universal Hospital Services, Inc. ("Universal") entered into a
definitive agreement for J.W. Childs Equity Partners, L.P. ("Childs") to
acquire Universal for $15.50 per share of Common Stock, $.01 par value, of
Universal. Including the assumption of debt and payment of transaction-related
expenses, the total purchase price is approximately $133 million. Certain
members of UHS management, led by David E. Dovenberg, the Chief Financial
Officer of UHS, are participating in the transaction and will retain an equity
interest in UHS. The transaction is structured as a cash merger and is
intended to be treated as a recapitalization for accounting purposes. The
Board of Directors of UHS has unanimously approved the merger agreement. The
merger, which requires UHS shareholder approval and Hart-Scott-Rodino
clearance and is subject to funding of committed financing, is expected to
close in February 1998. Piper Jaffray Inc. represents UHS in this transaction.
Childs has received financing commitments for the transaction from Bankers
Trust Company, which commitments are subject to customary conditions.

                          AGREEMENT AND PLAN OF MERGER



          THIS AGREEMENT AND PLAN OF MERGER (the "Agreement"), dated as of
November 25, 1997, is by and among UHS ACQUISITION CORP., a Minnesota
corporation ("Acquiror"), J.W. CHILDS EQUITY PARTNERS, L.P., a Delaware limited
partnership ("Parent"), and UNIVERSAL HOSPITAL SERVICES, INC., a Minnesota
corporation (the "Company").

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

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

          WHEREAS, Acquiror, the Company and certain stockholders of the Company
have entered into agreements dated as of the date hereof (the "Support
Agreements") pursuant to which such stockholders have agreed, among other
things, to vote all shares of the Company's common stock owned by them in favor
of the merger.

          NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties and agreements contained herein, the parties hereto
agree as follows:


                                   ARTICLE I

                                  THE MERGER
                                  ----------

          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 such satisfaction or waiver, Acquiror will merge with
and into the Company (the "Merger").  The Company in its capacity as the
corporation surviving the Merger, is sometimes referred to herein as the
"Surviving Corporation."  The Merger will be effected pursuant to the provisions
of, and with the effect provided in, the Minnesota Business Corporation Act (the
"MBCA").

          Section 1.2.   Effective Date and Time.  Subject to the satisfaction
or waiver of the conditions set forth in Articles V and VI herein, the parties
hereto shall cause the Merger to be consummated by delivering to the Secretary
of State of the State of Minnesota appropriate articles of merger (the "Articles
of Merger"), in such form or forms as may be required by, and executed and
acknowledged in accordance with, the relevant and applicable provisions of the
MBCA.  The parties hereto shall cause the effective date of the Merger (the
"Effective Date") to occur on the date that the Articles of Merger are so filed
in accordance with the relevant provisions of the MBCA (or at such later time,
which shall be as soon as reasonably practicable, as may be specified in the
Articles of Merger).  The time on the Effective Date when the Merger shall
become effective is referred to as the "Effective Time."

          Section 1.3.   Effect of the Merger.  At the Effective Time, the
separate corporate existence of Acquiror shall cease and the Surviving
Corporation shall continue its corporate existence under the laws of the State
of Minnesota.  Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time all the property, rights, privileges, powers,
immunities and franchises of Acquiror and the Company shall vest in the
Surviving Corporation, and all debts, liabilities, obligations and duties of
Acquiror and the Company shall become the debts, liabilities, obligations and
duties of the Surviving Corporation.

          Section 1.4.   Subsequent Actions.  If, at any time after the
Effective Time, the Surviving Corporation shall consider or be advised that any
deeds, bills of sale, assignments, 
<PAGE>
 
assurances or any other actions or things are necessary or desirable to vest,
perfect or confirm of record or otherwise in the Surviving Corporation its
right, title or interest in, to or under any of the rights, properties or assets
of either of the Company or Acquiror acquired or to be acquired by the Surviving
Corporation as a result of, or in connection with, the Merger or otherwise to
carry out this Agreement, the officers and directors of the Surviving
Corporation shall be authorized to execute and deliver, in the name and on
behalf of either the Company or Acquiror, all such deeds, bills of sale,
assignments and assurances and to take, in the name and on behalf of each of
such corporations or otherwise, all such other actions and things as may be
necessary or desirable to vest, perfect or confirm any and all right, title and
interest in, to and under such rights, properties or assets in the Surviving
Corporation or otherwise to carry out the transactions contemplated by this
Agreement.

          Section 1.5.   Articles of Incorporation; Bylaws; Directors and
Officers.

          (a) Subject to Section 4.2(c), at the Effective Time, the Articles of
Incorporation of Acquiror, as in effect immediately before the Effective Time,
shall be the Articles of Incorporation of the Surviving Corporation until
thereafter amended as provided by the MBCA and the provisions of such Articles
of Incorporation, except that the name of the Surviving Corporation shall be
"Universal Hospital Services, Inc."

          (b) The Bylaws of Acquiror, as in effect immediately before the
Effective Time, shall become the Bylaws of the Surviving Corporation until
thereafter amended as provided by the MBCA, the provisions of the Articles of
Incorporation of the Surviving Corporation and such Bylaws.

          (c) The directors and officers of Acquiror immediately before the
Effective Time shall be the initial directors and officers of the Surviving
Corporation in each case until their successors are elected or appointed and
qualified.  If, at the Effective Time, a vacancy shall exist on the Board of
Directors or in any office of the Surviving Corporation, such vacancy shall
thereafter be filled in the manner provided by the MBCA, the Articles of
Incorporation and Bylaws of the Surviving Corporation.

          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) Except as may be otherwise agreed in writing between Acquiror and
      any holder thereof, each share of the Company's common stock, par value
      $.01 per share (the "Common Stock"), together with the associated Rights
      (as defined in Section 2.2), issued and outstanding immediately prior to
      the Effective Time (such shares, together with such Rights are herein
      referred to as the "Shares"), other than Shares canceled pursuant to
      Section 1.6(b) and Dissenting Shares (as defined in Section 1.7(b)), shall
      be canceled, extinguished and converted into and become a right to receive
      $15.50 in net cash per Share without any interest thereon (the "Merger
      Consideration"), subject to appropriate adjustment for any stock dividend,
      subdivision, reclassification, recapitalization, split, combination or
      exchange with respect to the Shares occurring before the Effective Time.

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

          (c) Each share of the Acquiror's common stock issued and outstanding
      immediately prior to the Effective Time shall be converted into and become
      one fully paid and nonassessable share of common stock of the Surviving
      Corporation.

                                      -2-
<PAGE>
 
          (d) As and to the extent provided in any written agreement between
      Acquiror and any holder of Shares, such holder's Shares shall not be
      canceled, extinguished or converted into the right to receive the Merger
      Consideration, but instead such Shares shall remain issued and outstanding
      as fully paid and nonassessable shares of common Stock of the Surviving
      Corporation.

          (e) As a result of their conversion pursuant to Section 1.6(a), all
      Shares (excluding any Dissenting Shares and any Shares described in
      Section 1.6(b) or 1.6(d)) 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 Section 1.6(b) or 1.6(d)) ("Converted Shares") shall thereafter solely
      represent the right to receive the Merger Consideration pursuant to
      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.

          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
302A.471 and 302A.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 any of the 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.  After the Effective Time, the
Surviving Corporation shall make any and all payments to holders of Shares
required by the MBCA to be made 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 302A.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 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.  Except as may be otherwise agreed in writing
between Acquiror and any holder of any Option (as hereinafter defined), 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 the Surviving Corporation a cash
payment (less applicable withholding taxes) in an aggregate amount equal to the
difference between the Merger Consideration less the applicable 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 

                                      -3-
<PAGE>
 
such accelerated vesting and rights pursuant to this Section 1.8 and obtaining
any requisite consents from holders of Options) as are necessary to fully advise
holders of Options of their rights under this Agreement and the Options, to
facilitate their timely exercise of such rights and to effectuate the provisions
of this Section 1.8(a). From and after the Effective Time, other than as
expressly set forth in this Section 1.8(a), no holder of an Option shall have
any other rights in respect thereof other than to receive payment for his or her
Options equal to the Option Consideration, and the Company shall take all
necessary actions to terminate effective as of the Effective Time the Company's
stock option plans, agreements 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 on December 31, 1996 and thereafter 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 upon payment to the Company of the consideration required by
the ESPP.  The Company shall take all necessary action to terminate the ESPP as
of the Effective Time and thereafter no purchase rights under the ESPP shall be
granted or exercised.

          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, Acquiror shall designate a bank
or trust company reasonably acceptable to the Company to act as agent for the
holders of the Shares and Options (the "Exchange Agent") for the purpose 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, the Surviving Corporation shall remit to
the Exchange Agent an amount equal to 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 

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

          (i) Promptly following the six-month 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 abandoned property,
escheat or similar law.


                                   ARTICLE II

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

          The Company represents and warrants to Parent and 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 the Support
Agreements and to carry out the transactions contemplated hereby and thereby.

          (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, 

                                      -5-
<PAGE>
 
      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 and be in 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, Parent or Acquiror, as applicable,
      any effect, change or event that individually or in the aggregate when
      taken together with all similar effects, changes or events (i) is or is
      reasonably likely to be material and adverse to the assets, liabilities,
      condition (financial or otherwise), results of operations, cash flows or
      business of the Company, Parent or Acquiror, respectively, or (ii) does or
      is reasonably likely to impair materially the ability of the Company,
      Parent or Acquiror, respectively, to perform its obligations under this
      Agreement or otherwise to threaten materially or to impede materially the
      consummation of the Merger and the other transactions contemplated by this
      Agreement; provided, however, that Material Adverse Effect with respect to
      the Company shall not be deemed to include the impact of actions or
      omissions of the Company taken with the prior written consent of Parent or
      Acquiror, in contemplation of the transactions contemplated by this
      Agreement.

          (c) The Company does not have any subsidiaries.  For purposes of this
Agreement, "subsidiary" of any party 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 such party.  Except as set forth in Schedule
2.1(c), the Company (i) does not directly or indirectly own, (ii) has not agreed
to purchase or otherwise acquire or (iii) does not hold any interest convertible
into or exchangeable or exercisable for, 5% or more of the capital stock or
other equity interest of any corporation, partnership, company, joint venture or
other business association or entity.  Except as set forth in Schedule 2.1(c),
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.  There are no voting trusts, proxies or
other agreements or understandings to which the Company is a party or by which
the Company is bound with respect to the voting of any shares of capital stock
of the Company or any other entity required to be disclosed on Schedule 2.1(c).

          (d) The execution, delivery and performance by the Company of this
Agreement and the Support Agreements and the consummation by the Company of the
transactions contemplated hereby and thereby have been duly authorized by the
Board of Directors of the Company and, except for obtaining the approval of the
Company's shareholders to the Merger as contemplated by Section 4.2(j) hereof,
no further corporate authorization on the part of the Company is necessary to
consummate the transactions contemplated by this Agreement or the Support
Agreements.

          (e) Each of this Agreement and the Support Agreements has been duly
executed and delivered by the Company, and, assuming the due and valid
authorization, execution and delivery hereof and thereof by the other parties
hereto and thereto, each of this Agreement and the Support Agreements
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).

          (f) The copies of the Articles of Incorporation and Bylaws, and all
amendments thereto, of the Company 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,

of the Junior Preferred Stock (the "Rights"), pursuant that certain Rights
Agreement dated as of November 8, 1996, as amended, between the Company and
Norwest Bank Minnesota N.A., as Rights Agent (the "Rights Agreement"). Schedule
2.2 sets forth a schedule showing (i) each outstanding Option and the date it
was granted; (ii) the number of shares of Common Stock subject thereto (assuming
full acceleration of vesting as provided in such Options and in Section 1.8);
(iii) the exercise price, and (iv) the method by which the number of shares of
Common Stock issuable pursuant to Section 1.8(b) under the ESPP may be
determined. All of the outstanding shares of the Company's Common Stock are, and
all shares of Common Stock which may be issued pursuant to the exercise of
outstanding Options or under the ESPP pursuant to Section 1.8(b) will be, when
issued in accordance with the respective terms thereof, duly authorized, validly
issued, fully paid and nonassessable, issued in material compliance with all
applicable federal and state securities laws and not 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. There are no bonds, debentures, notes
or other indebtedness having general voting rights (or convertible into
securities having such rights) ("Voting Debt") of the Company issued and
outstanding. 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 authorized, issued or outstanding and no other options,
warrants, rights to subscribe to (including any preemptive rights), calls,
agreements, arrangements or commitments of any character whatsoever to which the
Company is a party or may be bound requiring the issuance, transfer or sale of
any shares of capital stock, Voting Debt or other equity interests of the
Company or any securities or rights convertible into or exchangeable or
exercisable for any such shares or equity interests, and there are no contracts,
commitments, understandings or arrangements by which the Company is or may
become bound to issue additional shares of its capital stock, options, warrants
or rights or to purchase, redeem or acquire any 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) Neither the execution or delivery of this Agreement or the Support
Agreements nor the consummation of the transactions contemplated hereby or
thereby does or will:

               (i) violate, conflict with, or constitute a default under, the
      Articles of Incorporation, as amended, or Bylaws, as amended, of the
      Company; 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) violate any statute or
      law or any rule, regulation, order, writ, injunction, judgment or decree
      of any court or governmental authority to which the Company or any of its
      assets or properties is subject or (B) except as disclosed on Schedule
      2.3(a) hereto, result in a violation or breach of, or constitute (with or
      without notice or lapse of time or both) a default under, or give rise to
      any right of termination, acceleration or modification of, any note, bond,
      mortgage, indenture, deed of trust, license, lease or other agreement,
      instrument or obligation to which the Company is a party or by which it or
      any of its assets or properties may be bound, which default, breach or
      other action individually or in the aggregate has or would reasonably be
      expected to have a Material Adverse Effect on the Company.

          (b) Except for the expiration or termination of the applicable waiting
period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), and in connection with the MBCA, the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), 

                                      -7-
<PAGE>
 
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 (i) court,
arbitral tribunal, administrative agency or commission or other governmental,
regulatory or administrative authority or (ii) other person or entity required
to be obtained by the Company in connection with the execution of this Agreement
or the Support Agreements by the Company and the consummation of the
transactions contemplated hereby or thereby.

          Section 2.4.   SEC Filings.

          (a) Prior to the execution of this Agreement, the Company has timely
filed and has delivered or made available to Acquiror complete and accurate
copies of all forms, reports, schedules, statements and other documents required
to be filed by it since January 1, 1995 under the Exchange Act or the Securities
Act of 1933, as amended (together with all subsequent forms, reports, schedules,
statements and other documents filed by the Company with the United States
Securities and Exchange Commission (the "SEC") prior to the Effective Date,
collectively, the "Company Public Reports"), including without limitation

1996, 1995 and 1994, as amended, as filed under the Exchange Act with the SEC,

not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading and
(y) complied in all material respects with the applicable laws and rules and
regulations of the SEC.  Since January 1, 1995, no subsidiary of the Company has
been required to file any forms, reports, or other documents with the SEC.

          (b) The financial statements of the Company (including any footnotes
thereto) contained in the Company Public Reports have been prepared from, and
are in accordance with, the books and records of the Company and its
consolidated subsidiaries and have been prepared in accordance with the
published rules and regulations of the SEC and generally accepted accounting
principles applied on a consistent basis during the periods involved (except as
may be otherwise indicated therein) and fairly presented the consolidated
financial position of the Company and its subsidiaries (if any) as of the dates
thereof and the consolidated results of operations, changes in shareholders'
equity and cash flows of the Company and its subsidiaries (if any) for the
periods then ended, except that any unaudited financial statements contained
therein are subject to normal and recurring year-end adjustments.

          Section 2.5.   No Material Adverse Changes.  Since December 31, 1996
and on or prior to the date hereof, except as set forth on Schedule 2.5 or in
the Company Public Reports filed prior to the date hereof, there has been no
change, event, loss, occurrence or development in the business of the Company
(including the incurrence of any liability of any nature, whether accrued,
contingent or otherwise) 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, as
contemplated in this Agreement or as set forth in Schedule 2.5, since December
31, 1996 and prior to the date hereof, the Company has conducted its business
only in the ordinary course and in a manner consistent with past practice, and
the Company has not taken any action which, if taken after the date hereof,

          Section 2.6.   Legal Proceedings.  Except as set forth on Schedule 2.6
attached hereto, there are no, and since January 1, 1995 there have not been
any, claims, actions, suits, proceedings (arbitration or otherwise) or
investigations pending or, to the Company's knowledge, threatened against, the
Company or any of its subsidiaries.   Except as set forth on Schedule 2.6, no
such claims, actions, suits, proceedings or investigations (i) are seeking to
enjoin, prohibit, restrain or otherwise prevent the transactions contemplated
hereby or (ii) would, if adversely determined, be reasonably 

                                      -8-
<PAGE>
 
likely to result in a Material Adverse Effect on the Company. There are no
judgments, decrees or orders issued by any court, board or other governmental or
administrative agency presently outstanding and unsatisfied against the Company.

          Section 2.7.   No Dividends or Distributions.  Since December 31,
1996, there has not been any declaration, setting aside or payment of any
dividend or any other distribution with respect to the Company's capital stock
or any redemption, purchase or other acquisition of any of the Company's
securities.

          Section 2.8.   Disclosure Documents.

          (a) The Proxy Statement (as defined in Section 4.2(j)), and any
amendments or supplements thereto, will, when filed, comply as to form in all
material respects with the applicable requirements of the Exchange Act and the
rules and regulations thereunder.

          (b) At the time the Proxy Statement or any amendment or supplement
thereto is first mailed to shareholders of the Company and at the time such
shareholders vote on adoption of this Agreement, the Proxy Statement, as
supplemented or amended, will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading.  The representations
and warranties contained in paragraphs (a) and (b) of this Section 2.8 will not
apply to statements or omissions included in the Proxy Statement, based upon
information furnished to the Company in writing by Acquiror or Parent
specifically for use therein.

          (c) At the time of the filing of the Schedule 13E-3 (as defined in
Section 4.2(j)), at the time of any distribution thereof and until the Effective
Date, none of the information supplied by the Company specifically for inclusion
or incorporation by reference in the Schedule 13E-3 will contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading.

          Section 2.9.   Tax Matters.

          (a) Except as set forth in Schedule 2.9, the Company has filed all Tax
Returns required to be filed by it (or any subsidiary) on or prior to the
Effective Date and has 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 covered by such returns (except where the failure to pay
would not have a Material Adverse Effect on the Company).  The information
contained in such Tax Returns is true, complete and accurate in all material
respects.  The Company is not delinquent in the payment of 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 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 any of its subsidiaries 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 any of its subsidiaries.  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
Internal Revenue Code of 1986, as amended (the "Code")).  Neither the Company
nor any of its subsidiaries has made an election under Section 341(f) of the
Code.  Neither the Company nor any of its subsidiaries has been a United States
real property holding corporation within the meaning of Section 897(c)(2) of the
Code during the past five years.

                                      -9-

          (b)  For Purposes of this Agreement:

               (i) "Tax or Taxes" means any federal, state, county, local or
      foreign taxes, charges, fees, levies, or other assessments, including all
      net income, gross income, sales and use, ad valorem, transfer, gains,
      profits, excise, franchise, real and personal property, gross receipts,
      capital stock, production, business and occupation, disability,
      employment, payroll, license, estimated, stamp, custom duties, severance

      any such taxes; and

               (ii) "Tax Return" means a report, return or other information
      required to be supplied to a governmental entity with respect to Taxes
      including, where permitted or required, combined or consolidated returns
      for 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 balance sheet as of September 30, 1997 included in the
Company's Quarterly Report on Form 10-Q delivered to Acquiror pursuant to
Section 2.4 (the "Latest Balance Sheet") in accordance with generally accepted
accounting principles have been so reflected. The Company has no Liabilities
which are, in the aggregate, material to the business, assets, operations or
financial condition of the Company, 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 consistent with past practice
and which were not required under generally accepted accounting principles 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
consistent with past practice, and (d) as otherwise disclosed on Schedule 2.10.

          Section 2.11.   Compliance with Laws; Permits. The Company and its
subsidiaries have complied in all respects with all applicable laws and
regulations of foreign, federal, state and local governments and all agencies
thereof ("Laws") which affect the business, assets or any owned or leased
properties of the Company or any of its subsidiaries or to which the Company or
any of its subsidiaries may otherwise be subject (including, without 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 claim has been filed, commenced or, to the Company's knowledge,
threatened against the Company or any of its subsidiaries by any such
governments or agencies relating to any alleged violation of any such law or
regulation which has not been resolved to the satisfaction of such governments
or agencies. Since December 31, 1994, neither the Company nor any subsidiary of

any event or circumstance that exists which (A) may constitute or result in a
violation by the Company of, or the failure on the part of the Company to comply
with such Permits or Environmental Laws, or (B) may give rise to any obligation
on the part of the Company to undertake, or to bear all or any portion of the
cost of any Cleanup which, in the case of clauses (A) or (B), could have a
Material Adverse Effect on the Company.

          (e) To the knowledge of the Company, there have been no releases,

Acquiror or Parent or any of their respective assets or properties is subject or
(z) result in a violation or breach of, or constitute (with or without notice or
lapse of time or both) a default under, or give rise to any right of
termination, acceleration or modification of, any material contract or agreement
of any kind to which Acquiror or Parent is a party or by which it or any of its
assets or properties may be bound which default, breach or other action
individually or in the aggregate has or would reasonably be expected to have a
Material Adverse Effect on Acquiror and Parent, taken as a whole.

          Section 3.4.    Approvals or Consents. Except for the expiration or
termination of the applicable waiting period under the HSR Act, and in
connection with the MBCA, the Exchange Act, 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 (i) court, arbitral
tribunal, administrative agency or commission or other federal, governmental,
regulatory or administrative authority or (ii) other person or entity required
to be obtained by Acquiror or Parent in connection with the execution of this
Agreement by Acquiror or Parent and the consummation of the transactions
contemplated hereby.

          Section 3.5.   Legal Proceedings. Except as set forth on Schedule 3.5
attached hereto, there are no claims, actions, suits, proceedings or

otherwise prevent the transactions contemplated hereby or (ii) which are
reasonably likely to impair materially the ability of Acquiror or Parent to
fulfil its respective obligations under this Agreement or to impede 

                                      -17-

materially or threaten to impede materially the consummation of the transactions
contemplated hereby.

          Section 3.6.   Financing. Parent has received commitments from
financial institutions in the amount of $95 million and prior to the Effective
Time Acquiror will receive capital from Parent or other investors selected by
Parent in an amount sufficient to satisfy the equity financing requirement of
any debt financing commitment selected by Parent to be drawn upon in order to
consummate the transactions contemplated hereby (which capital amount would be
not less than $49.1 million in the event the commitments from financial
institutions referred to above are to be drawn upon). True correct and complete
copies of such commitments from financial institutions are attached hereto as
Schedule 3.6. At the Effective Time, assuming the funding of such commitments

necessary to consummate the Merger including, but not limited to, paying the
aggregate Merger Consideration and Option Consideration to all holders of Shares
and Options, paying all severance obligations pursuant to Section 4.2, paying
all fees and expenses incurred by it and refinancing all indebtedness of the

          Section 3.7.    Disclosure Documents.

          (a) The Schedule 13E-3 and any amendments or supplements thereto,
will, when filed, comply as to form in all material respects with the applicable
requirements of the Exchange Act and the rules and regulations thereunder.

          (b) At the time of the filing of the Schedule 13E-3, at the time of
any distribution thereof and until the Effective Date, the Schedule 13E-3, as
supplemented or amended, will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading.  The representations
and warranties contained in paragraphs (a) and (b) of this Section 3.7 will not
apply to statements or omissions included in the Schedule 13E-3, based upon
information furnished to Acquiror, Parent or any affiliate thereof by the
Company specifically for use therein.

          (c) At the time the Proxy Statement or any amendment or supplement
thereto is first mailed to shareholders of the Company and at the time such
shareholders vote on adoption of this Agreement, none of the information
supplied by the Acquiror or Parent specifically for inclusion or incorporation
by reference in the Proxy Statement will contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading.

          Section 3.8.    Fraudulent Transfer Laws. Assuming the Company is not
insolvent (as defined below) prior to the Effective Time and assuming the
satisfaction of the conditions in Sections 5.4 and 5.5 hereof, immediately after
the Effective Time and after giving effect to any change in the Surviving
Corporation's assets and liabilities as a result of the Merger, the Surviving
Corporation will not be insolvent. For purposes hereof, an entity will be deemed
to be "insolvent" if (i) such entity's financial condition is such that either
the sum of its debts is greater than the fair value of its assets or the fair
salable value of its assets is less than the amount required to pay its probable
liability on existing debts as they mature, (ii) such entity has unreasonably
small capital with which to engage in its business or (iii) such entity has
incurred liabilities beyond its ability to pay as they become due. The
representation and warranty set forth in this Section 3.8 shall be deemed to be
made only at the Effective Time.

the circumstances under which they were made, not misleading.

          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 use its best efforts to cause the officers, directors,
          employees, representatives and agents (including, without limitation,
          attorneys, investment bankers and accountants) of the Company 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 agree to or endorse, approve or
          recommend any Acquisition Proposal, or enter into discussions or
          negotiate with or provide any information to any person or entity in
          furtherance of any such inquiries or to obtain or approve any
          Acquisition Proposal, except that nothing contained in this Section
          4.1 or any other provision of this Agreement shall prohibit the
          Company or the Company's Board of Directors from (i) taking and
          disclosing to the Company's shareholders a position with respect to a
          tender or exchange offer by a third party pursuant to Rules 14d-9 and
          14e-2 promulgated under the Exchange Act, or (ii) making such
          disclosure to the Company's shareholders as, in the good faith
          judgment of the Board, after receiving advice from outside counsel, is
          required under applicable law, provided that the Company may not,
          except as permitted by Section 4.1(a)(ii), withdraw or modify, or
          propose to withdraw or modify, its position with respect to the Merger
          or approve or recommend, or propose to approve or recommend any
          Acquisition Proposal, or enter into any agreement with respect to any
          Acquisition Proposal. For purposes hereof, "Acquisition Proposal"
          means any proposal or offer to acquire all or a substantial part of
          the business and properties of the Company or any capital stock of the
          Company,whether by merger, tender offer, exchange offer, sale of
          assets or similar transactions involving the Company.

               (ii) Nothing contained in this Section 4.1 or any other provision
          of this Agreement shall prohibit the Company or the Company's Board of
          Directors from notifying any third party that contacts the Company on
          an unsolicited basis after the date hereof concerning an Acquisition
          Proposal of the Company's obligations under this Section 4.1.
          Notwithstanding this Section 4.1 or any other provision of this
          Agreement, prior to the Effective Time, the Company may furnish
          information concerning the Company to any corporation, partnership,
          person or other entity or group pursuant to appropriate
          confidentiality agreements, and may negotiate and participate in
          discussions and negotiations with such entity or group if (w) such
          entity or group has on an unsolicited basis submitted a bona fide
          written proposal to the Company pursuant to which such person or group
          would acquire all or substantially all of the businesses and
          properties of the Company or at least a majority of the Shares
          outstanding on a fully diluted basis, (x) such entity or group is
          financially capable of consummating such transaction, (y) the Board of
          Directors of the Company determines in good faith (after consultation
          with its financial advisors) that such proposed transaction represents
          a superior transaction to the Merger and (z) the Board of Directors of
          the Company has determined, after receipt of advice from outside legal
          counsel to the Company, that the failure to provide such information
          or access or to engage in such discussions or negotiations could
          reasonably be expected to cause the Board of Directors to not to
          fulfill its fiduciary duties to the Company's shareholders under
          applicable law (a proposal which satisfies clauses (w) through (z)
          being

                                      -19-

          referred to herein as a "Superior Proposal"). The Company will notify
          Acquiror within two business days of the existence of any proposal
          relating to any Acquisition Proposal received by or actually known to
          the Company, the identity of the party making such proposal, and the
          terms (both initial and as may be modified) of any such proposal, and
          the Company will keep Acquiror reasonably informed of the status
          (including any amendments or proposed amendments) of any such
          proposal. At any time after five business days following notification
          to Parent of the Company's intent to do so (which notification shall
          include the identity of the bidder and the material terms and
          conditions of the proposal) and if the Company has otherwise complied
          with the terms of this Section 4.1(a)(ii), the Board of Directors may
          withdraw or modify its approval or recommendation of the Merger in
          order concurrently to enter into a definitive agreement with respect
          to a Superior Proposal, provided it shall concurrently with entering
          into such agreement pay or cause to be paid to Parent the sum of $2.6
          million (the "Break-Up Fee"). If the Company shall have notified
          Parent of its intent to enter into an agreement with respect to a
          Superior Proposal in compliance with the preceding sentence and has
          otherwise complied with such sentence, the Company may enter into a
          definitive agreement with respect to such Superior Proposal (with the
          bidder and on terms no less favorable than those specified in such
          notification) after the expiration of the initial five business day
          period without any further notification.

          (b) Conduct of the Company's Business and Operations.  Except as
expressly provided in this Agreement or as agreed in writing by Parent and
Acquiror, from the date hereof to the Effective Date, the Company covenants and

          employees and preserve its relationships with customers, suppliers and
          others having business dealings with it. The Company shall: (A)
          maintain insurance coverages and its books, accounts and records in

          excepted; and (D) perform its obligations under all contracts and
          commitments to which it is a party or by which it is bound, in each
          case 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) amend
          its Articles of Incorporation or Bylaws; (B) split, combine or
          reclassify its outstanding capital stock or issue or authorize or
          propose the issuance of any other securities in respect of, in lieu of

          declare, set aside or pay any dividend or other distribution payable
          in cash, stock or property; or (C) directly or indirectly redeem,
          purchase or otherwise acquire or agree to redeem, purchase or
          otherwise acquire any shares of Company capital stock; or (D) create
          any subsidiary of the Company;

               (iii) The Company shall not: (A) except as required by this
          Agreement and pursuant to Option Agreements outstanding on the date
          hereof or under the ESPP as in effect on the date hereof, issue,
          deliver or sell or agree to issue, deliver or sell any additional
          shares of, or rights of any kind to acquire any shares of, its capital
          stock of any class, any Voting Debt or indebtedness or any options,
          rights or warrants to acquire, or securities convertible into, shares
          of capital stock; (B) acquire, lease or dispose of or agree to
          acquire, lease or dispose of any interest in any capital assets or any
          other assets other than in the ordinary course of business and
          consistent with past practice; (C) incur additional indebtedness or
          encumber or grant a security interest in any asset or enter into any

          of incurring additional indebtedness, in any event in an amount not
          more than $3.0 million in excess of the amount reflected on the Latest
          Balance Sheet); (D) acquire or agree to acquire by merging

          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); (E) permit any insurance policy naming the
          Company as a beneficiary or a loss payable payee to be canceled or
          terminated without notice to Parent, except in the ordinary course of
          business and consistent with past practice; (F) assume, guarantee,

          contingently or otherwise) for the obligations of any other person or

          and that, in the aggregate, do not result in a material increase in
          benefits or compensation expense to the Company relative to the level
          of such expense in effect prior to such increase); (C) pay any benefit
          not provided under any existing plan or arrangement; (D) grant any

<PAGE>
 
               (ix) except as permitted by Section 4.1(a) hereof, the Company
          will not enter into any agreement, contract, commitment or arrangement
          to do any of the foregoing, or to authorize, recommend, propose or

          Section 4.2.   Additional Covenants of Acquiror, Parent and the 
                         the Company.

          (a) Employee Benefits.  As of the Effective Time, the employees of the
Company (the "Company Employees") shall continue employment with the Surviving
Corporation, 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 shall not be obligated to
continue any employment relationship with any Company Employee for any period of
time.  In addition to any obligation required by law or under any plan of the
Company disclosed on Schedule 2.14, Acquiror, Parent and the Company agree that
Company Employees whose employment is terminated on or after the Effective Date
or within 12 months thereafter will receive severance payments pursuant to
policy attached hereto as Schedule 4.2.  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:  (i) service with the Company (or any
subsidiary of the Company) by any Company Employee prior to the Effective Time
shall be credited in determining such employee's eligibility, vesting and
benefit levels, and (ii) with respect to any welfare benefit plans in which such
employees may become eligible to participate, 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 for Company Employees prior to the Effective
Time, effective upon the Effective Time.  The Surviving Corporation expressly
assumes and agrees to be bound by the terms of the change in control agreements
set forth on Schedule 4.2 at 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, 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 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 (if any) 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.  Subject to
the occurrence of the Effective Date, until the six year anniversary date of the
Effective Date, the Surviving Corporation will 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 at any time prior to the Effective Date which are comparable to such
provisions as are currently contained in the Company's Articles of Incorporation
and Bylaws.  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 

                                      -22-
<PAGE>
 
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). The
Surviving Corporation shall 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 the Surviving
Corporation may substitute therefor a policy or policies providing substantially
equivalent 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 the Surviving
Corporation 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 the Surviving Corporation is unable to obtain the amount of
insurance required by this Section 4.2(c) for such aggregate premium, the
Surviving Corporation shall obtain as much insurance as can be obtained for an
annual premium not in excess of the Maximum Premium. The Surviving Corporation

the Company, Acquiror and Parent shall not take, and shall cause its respective
subsidiaries (if any) not to take, or agree in writing or otherwise to take, any
actions that would (i) make any representation or warranty of the Company,
Acquiror or Parent, respectively, 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.

          (e) Access to Information.  The Company will (and will cause each of
its 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 as is reasonable 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, Acquiror and Parent shall use their
reasonable 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

reasonable business efforts to achieve the prompt termination of the expiration
of the waiting period under the HSR Act.

          (g) Reasonable Best Efforts.  Parent, Acquiror and the Company will

consummate the Merger on the terms and conditions set forth in this Agreement.
Without limiting the foregoing, Acquiror shall use commercially reasonable
efforts to obtain and to cause to be made available to the Surviving Corporation
all funds necessary to pay the aggregate Merger Consideration and Option
Consideration to all holders of Shares and Options, to pay all severance
obligations pursuant to Section 4.2, to pay all fees and expenses incurred by it
and to refinance all indebtedness of the Company that will or may come due as a
result of the Merger, and the Company shall, and shall cause its
representatives, employees and advisors to, at the Company's

transactions contemplated hereby, including without limitation (i) making
available on a timely basis any financial information of the Company and its
subsidiaries that may be requested, (ii) obtaining comfort letters and updates
thereof from the Company's independent certified public accountants, with such
letters to be in customary form and to cover matters of the type customarily
covered by accountants in such financing transactions, and (iii) making
available representatives and employees of the Company and its accountants and
attorneys in connection with any such financing, including for purposes of due
diligence and marketing efforts related thereto. In case at any time after the
Effective Time any further action is necessary or desirable to carry out the
purposes of this Agreement, the proper officers and directors of the Company,
Parent and Acquiror shall use all reasonable efforts to take, or cause to be
taken, all such necessary actions. Nothing in this Agreement shall require
Parent or Acquiror to make available equity financing in excess of $49.1 million
or otherwise to seek or accept debt financing on terms less favorable to Parent
and Acquiror than the terms of the commitments from financial institutions
referenced in Section 3.6.

          (h) Certain Filings.  The Company, Acquiror and Parent shall each use
all reasonable 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.

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; Proxy Statement; Schedule 13E-3.

                 (i) The Company shall, in accordance with applicable law and

                 (B) as promptly as practicable, prepare and file with the SEC a
          proxy statement, and any amendment or supplement thereto, relating to

          required to be included by the SEC in the Proxy Statement and after

          the Company without consultation with Acquiror and its counsel and (y)
          to obtain the necessary approvals of the Merger and this Agreement by
          its shareholders; and

          Statement the recommendation of the Board that shareholders of the

     law) shall prepare and file with the SEC, together with the Company, a Rule
     13E-3 Transaction Statement on Schedule 13E-3 (together with all
     supplements and amendments thereto, the "Schedule 13E-3") with respect to
     the transactions contemplated by this Agreement. The Company shall promptly
     furnish to Acquiror all information concerning the Company as may
     reasonably be requested in connection with the preparation of the Schedule
     13E-3. The Company shall promptly supplement, update and correct any
     information provided by it for use in the Schedule 13E-3 if and to the
     extent that it is or shall have become incomplete, false or misleading. In
     any such event, Acquiror and the Company shall take all steps necessary to
     cause the Schedule 13E-3 as so supplemented, updated or corrected to be
     filed with the SEC and to be disseminated to the holders of Shares, in each
     case, as and to the extent required by applicable federal securities laws.
     The Company shall be given an opportunity to review and comment on the
     Schedule 13E-3 and each supplement, amendment or response to comments with
     respect thereto prior to its being filed with or delivered to the SEC.

                 (iii) Parent and Acquiror shall promptly furnish to the Company
     all information with respect to Parent and Acquiror as may be reasonably
     requested in connection with the preparation of the Proxy Statement.
     Acquiror and Parent shall promptly supplement, update and correct any
     information provided by it for use in the Proxy Statement if and to the
     extent that it is or shall have become incomplete, false or misleading.

                 (iv) Acquiror and Parent shall vote, or cause to be voted, any
     Shares owned by them or any of their respective affiliates in favor of the
     approval of the Merger and the approval and adoption of this Agreement.

          (k) Notification of Certain Matters.  The Company shall give prompt
notice to Parent and Parent shall give prompt notice to the Company, of (i) the
occurrence, or non-occurrence of any event the occurrence, or non-occurrence of

               J.W. CHILDS TO ACQUIRE UNIVERSAL HOSPITAL SERVICES

     BLOOMINGTON, MN (November 26)-- Universal Hospital Services, Inc. ("UHS")
(NASDAQ: UHOS) and J.W. Childs Equity Partners, L.P. ("Childs") have announced
that they have entered into a definitive agreement for Childs to acquire UHS for
$15.50 per UHS share.  Including the assumption of debt and payment of
transaction-related expenses, the total purchase price is approximately $133
million.  Certain members of UHS management, led by David E. Dovenberg, the
Chief Financial Officer of UHS, are participating in the transaction and will
retain an equity interest in UHS.

     Thomas A. Minner, UHS's President and Chairman of the Board, said: "We are
especially pleased that the thorough and extended process of evaluating the
Company's alternatives has resulted in a transaction which the Board believes
best serves the interests of its shareholders.  In addition, it is our belief
that this transaction preserves many of the positive values and aspects of the
UHS enterprise while assuring stability for our employees and continuity of
service to our valued customers."

     "We are delighted to be working with Dave Dovenberg and other UHS employees
to allow the company to remain independent and entrepreneurial," said Steven
Segal, Managing Director of J.W. Childs Associates.  "We are excited to provide
the capital necessary for management to continue to invest in new equipment
which will insure product availability, support advances in technology and
provide the superior quality and service that customers, vendors and employees
have come to expect from UHS."

     The transaction is structured as a cash merger and is intended to be
treated as a recapitalization for accounting purposes.  The Board of Directors
of UHS has unanimously approved the merger agreement.  The merger, which
requires UHS shareholder approval and Hart-Scott-Rodino clearance and is subject
to funding of committed financing, is expected to close in February 1998.  Piper
Jaffray Inc. represents UHS in this transaction.  Childs has received financing
commitments for the transaction from Bankers Trust Company, which commitments
are subject to customary conditions.

     UHS provides movable medical equipment to over 3,300 hospitals and
alternate care providers principally through Pay-per-Use equipment management
programs.  Under UHS's rental programs, health care providers are charged a per
use rental fee based on actual usage.   In addition, UHS sells disposable
supplies related to the equipment it rents.  UHS operates through 46 district
offices and eight regional service centers serving customers in 50 states in
five primary equipment categories--critical care, monitoring, newborn care,
respiratory care and specialty beds.

     J.W. Childs Associates is a private investment firm based in Boston focused
on investing in middle market growth companies.  The firm manages $463 million
of committed equity capital.  Recent investments include Personal Care Group,
Chevy's "Fresh Mex" restaurants, Empire Kosher Poultry and Central Tractor Farm
and Country.
