                                ARTICLE II

                                The Closing

     2.01     The Exchanges.  At the Effective Time and subject to the terms
and conditions of this Agreement, the VSCA and the BCL, (a) all of the
outstanding shares of SMI Common Stock other than Dissenting Shares (as
defined in the SMI Plan of Exchange) will be exchanged for the SMI Exchange
Consideration and the SMI Exchange Consideration shall be allocated among the
holders of SMI Common Stock in accordance with their elections made pursuant
to the SMI Plan of Exchange and (b) each of the outstanding shares of O&M
Common Stock will be exchanged for one share of O&M Holding Common Stock.

     2.02     Closing; Filing of Articles of Exchange.  Upon the terms











and subject to the conditions hereof, as soon as practicable after all of the
conditions to the obligations of the parties hereunder have been satisfied or
waived, the parties shall conduct the Closing for the purpose of confirming
the foregoing.  As soon as practicable after the Closing, (a) SMI shall in
the manner required by the BCL deliver to and file with the Department of
State of the Commonwealth of Pennsylvania the duly executed SMI Articles of
Exchange in accordance with the provisions of the BCL, (b) O&M Holding shall
in the manner required by the VSCA deliver to and file with the Commonwealth
of Virginia State Corporation Commission the duly executed O&M Articles of
Exchange in accordance with the VSCA and (c) the parties hereto shall take
all such other action as may be required by law to make the Exchanges
effective.

     2.03     Holdback Shares.

          (a)  At the Effective Time, O&M Holding shall issue and retain,
pending final determination of the Closing Balance Sheet pursuant to the
provisions of Section 2.05 hereof, from the SMI Exchange Consideration to be
received by each Shareholder, certificates representing 3% of that number of
shares (rounded up to the nearest whole share) of the O&M Holding Preferred
Stock that would be issued to such Shareholder if the cash election permitted
by Section 3.02 of the SMI Plan of Exchange were not exercised by any holder
of SMI Common Stock in the SMI Exchange (the "Balance Sheet Holdback Shares")
.  The Balance Sheet Holdback Shares shall be held and delivered as provided
in Section 2.05 hereof.

          (b)  At the Effective Time, O&M Holding shall issue and retain from
the SMI Exchange Consideration to be received by the Shareholders,
certificates representing in the aggregate that number of shares of O&M
Holding Preferred Stock (rounded up to the nearest whole share) determined by
dividing the outstanding principal balance (plus accrued interest thereon) of
the Subordinated Note as of the Effective Time by $100 (the "Subordinated
Note Holdback Shares").  The number of the Subordinated Note Holdback Shares
to be so retained in respect of each Shareholder (rounded to the nearest
whole share) shall be determined by multiplying the aggregate number of the
Subordinated Note Holdback Shares by a fraction, the numerator of which is
the number of shares of the O&M Holding Preferred Stock that would be
issued to such Shareholder in the SMI Exchange if the cash election permitted
by Section 3.02 of the SMI Plan of Exchange were not exercised by any holder,
and the denominator of which is the aggregate number of shares of the O&M
Holding Preferred Stock that would be so issued to all Shareholders in the
SMI Exchange under the same assumption.  Upon payment in full by SMI Funding
of the Subordinated Note within 150 days after the Effective Time (including
all accrued interest thereon to the date of payment), O&M Holding shall
promptly deliver to the Shareholder's Representative the share certificates
representing the Subordinated Note Holdback Shares (including any dividends
paid or distributions made with respect thereto and any interest thereon).
In the event SMI Funding fails to pay in full the Subordinated Note
(including accrued interest thereon) on or before 150 days after the
Effective Time, O&M Holding shall (a) retain and cancel ratably, in the same
proportion as the Subordinated Note Holdback Shares were withheld from the
Shareholders, the number of whole Subordinated Note Holdback Shares
(including any dividends paid or distributions made with respect thereto)
that when multiplied by $100 equals or exceeds by less than $100 the unpaid
principal amount of the Subordinated Note (less the accounts receivable











reserve reflected on the Closing Balance Sheet other than any reserve for the
Midwest Receivables) plus any unpaid accrued interest thereon through 150
days after the Effective Time and (b) shall assign without recourse the
Subordinated Note to the Shareholders' Representative.  O&M Holding shall
promptly deliver to the Shareholders' Representative any Subordinated Note
Holdback Shares (including any dividends paid or distributions made with
respect thereto and any interest thereon) not retained and canceled pursuant
to the preceding sentence.

     2.04     Voting of Holdback Shares; Dividends; Interest.  Each
Shareholder shall have full power to vote his respective Balance Sheet
Holdback Shares and Subordinated Note Holdback Shares in accordance with
Section 9.06 hereof.  Any dividends paid on or other distributions made with
respect to the Balance Sheet Holdback Shares or the Subordinated Note
Holdback Shares shall be invested by O&M Holding in any of the following
securities or accounts as designated in writing to O&M Holding by the
Shareholders' Representative:  (a) direct obligations of the United States of
America; (b) general obligations of any state or political subdivision
thereof if such obligations are rated by at least two nationally recognized
rating agencies as "AA" or higher; and (c) certificates of deposit of any
national bank or state bank member of the Federal Reserve System having an
aggregate capital and surplus of at least $100,000,000.

     2.05     Closing Balance Sheet.

          (a)  Within 60 days after the Effective Time, the Shareholders
shall cause E&Y to prepare a balance sheet of SMI as of April 30, 1994, (the
"Closing Balance Sheet") and the Shareholders shall deliver the Closing
Balance Sheet to O&M Holding together with a certificate signed by the
Shareholders certifying that the Closing Balance Sheet has been prepared in
accordance with GAAP (except for the absence of footnotes) and this Agreement
and fairly presents the assets and liabilities of SMI as of April 30, 1994.
The Closing Balance Sheet shall be prepared in accordance with GAAP (except
for the absence of footnotes); provided that:  (i) the Closing Balance Sheet
shall not include (x) any accounts receivable other than Midwest Accounts
Receivable or any accruals for the payments to be made by SMI with respect to
the Phantom Stock Plans in accordance with Section 6.14 hereof or (y) any
accrual of amounts that may be payable with respect to holders of Dissenting
Shares (as defined in the SMI Plan of Exchange); and (ii) the reserve for
obsolescent inventory on the Closing Balance Sheet shall include, without
limitation, the following (except with respect to inventory acquired from
U.S. Surgical that may be exchanged for other U.S. Surgical inventory without
additional cost to SMI):

                    (A)  a reserve for 100% of any item of inventory that has
               shown no arm's length and bona fide sales activity for a
               period of 12 months before the Effective Time (other than
               inventory purchased within 60 days before the Effective Time);


                    (B)  a reserve for 25% of any item of inventory, the on-
               hand quantities of which exceed two times the total cumulative
               arm's length and bona fide sales of such item during the 12
               months before the Effective Time, if SMI has made a
               substantial purchase of such item of inventory within 12











               months prior to the Effective Time; and

                    (C)  a reserve for 100% of any item of inventory, the on-
               hand quantities of which exceed two times the total cumulative
               arm's length and bona fide sales of such item during the 12
               months prior to the Effective Time, if SMI has not made a
               substantial purchase of such item of inventory within 12
               months before the Effective Time.

SMI's inventory shall be valued on a first-in, first-out basis at the lower
of cost or market value.  Commencing on April 30, 1994, SMI shall conduct,
and the Shareholders' Representative, or his designee, and E&Y shall observe,
a physical count of SMI's inventory as of April 30, 1994.  E&Y will make its
work papers available to SMI, the Shareholders' Representative, KPMG and O&M
Holding's representatives once E&Y has completed the Closing Balance Sheet.

          (b)  Within 30 days after delivery of the Closing Balance Sheet to
O&M Holding, O&M Holding may object to such balance sheet by delivering
written notice of such objection ("Notice of Objection") to the Shareholders'
Representative.  If no Notice of Objection is delivered in accordance with
the terms hereof, the Closing Balance Sheet shall be final and binding on the
parties to this Agreement without modification.  If a Notice of Objection is
delivered in accordance with the terms hereof, the Shareholders'
Representative and O&M Holding shall confer together and attempt in good
faith to agree upon a resolution of the objection.  If they have not agreed
upon such a resolution within 15 days after delivery of the Notice of
Objection, the disputed items on the Closing Balance Sheet shall be referred
to independent certified public accountants other than E&Y and KPMG (the
"Review Auditors") selected by mutual agreement of O&M Holding and the
Shareholders' Representative.  Within 30 days after the matter is referred to
them, the Review Auditors shall issue a report on their resolution of the
disputed items on the Closing Balance Sheet, which shall either confirm the
correctness thereof or state specifically the modifications to be made
thereto.  Upon delivery of such report to O&M Holding and the Shareholders'
Representative, the Closing Balance Sheet shall be deemed confirmed or
modified, as the case may be, in accordance therewith.  The Closing Balance
Sheet, as so confirmed or modified, shall be final and binding on all parties
to this Agreement.  O&M Holding and the Shareholders shall cooperate
fully with the Review Auditors and, following the Effective Time, each of O&M
Holding, on the one hand, and the Shareholders, on the other, shall bear one
half of the fees and expenses of the Review Auditors for the work undertaken
by them pursuant to this Section 2.05.

          (c)  O&M Holding shall retain and cancel, ratably in the same
proportion as the Balance Sheet Holdback Shares were withheld from the
Shareholders, the number of whole Balance Sheet Holdback Shares that, when
multiplied by $100 equals or exceeds by less than $100 any Net Worth
Deficiency and O&M Holding shall retain any dividends paid or distributions
made with respect thereto.  No later than ten days after the Closing Balance
Sheet becomes final and binding pursuant to Section 2.05(b) hereof, O&M
Holding shall deliver to the Shareholders' Representative certificates
representing any Balance Sheet Holdback Shares (including any dividends paid
or distributions made with respect thereto and any interest thereon) not
retained and canceled pursuant to the preceding sentence.  In the event the
aggregate par value of the Balance Sheet Holdback Shares is less than the Net











Worth Deficiency, then the Shareholders shall be obligated, jointly and
severally, to immediately pay to O&M Holding the amount of such shortfall.


                                ARTICLE III

                               The Exchanges

     At the Effective Time, by virtue of the Exchanges and without any action
on the part of SMI, O&M, O&M Holding, or the holders of O&M Common Stock or

immediately prior to the Effective Time (other than shares of SMI Common
Stock then held in the treasury of SMI) shall, by reason of the SMI Exchange

the right to receive the SMI Exchange Consideration (subject to adjustment

distribution or reclassification with respect to the outstanding SMI Common
Stock or O&M Common Stock, or any issuance of SMI Common Stock, from the date
hereof to the Effective Time, with any fractional shares of O&M Holding
Preferred Stock to which a holder of SMI Common Stock would otherwise be
entitled being rounded to the nearest full share (with a fraction of .5 or
greater being rounded to the next highest full share)).  The SMI Exchange
Consideration shall be allocated among the holders of SMI Common Stock in
accordance with such holders' elections made pursuant to Section 3.02 of the
SMI Plan of Exchange.

          (b)  Each share of SMI Common Stock held in the treasury of SMI
immediately prior to the Effective Time shall be automatically canceled and
retired and cease to exist, and no cash or securities or other property shall
be paid or payable in respect thereof.

          (c)  Each share of O&M Common Stock validly issued and outstanding
immediately prior to the Effective Time shall, by reason of the O&M Exchange
and without any action by any holder of O&M Common Stock, be exchanged for
the right to receive one share of O&M Holding Common Stock in accordance with
the O&M Plan of Exchange.


                                ARTICLE IV

                Representations of SMI and the Shareholders

     SMI and each of the Shareholders, jointly and severally, represent and
warrant as follows:

     4.01     Existence and Good Standing.  SMI is a corporation duly
organized and validly subsisting under the laws of the Commonwealth of
Pennsylvania and is duly qualified and in good standing to do business in
each jurisdiction in which the property owned, leased or operated by it or
the nature of the business conducted by it makes such qualification
necessary, except where the failure to be so qualified would not have a
material adverse effect on SMI's business or financial condition or would not
impair SMI's right to enforce any material agreement to which it is a party.











SMI has full power, authority and legal right to own its property and to
carry on its business as now being conducted.  SMI has delivered to O&M true
and complete copies of its Articles of Incorporation, as amended, and Bylaws,
as currently in effect.

     4.02     Authorization.  SMI has corporate power and authority to
execute and deliver this Agreement and to consummate the transactions
contemplated hereby.  Each of the Shareholders has power and authority to
execute and deliver this Agreement and the Related Agreements and to
consummate the transactions contemplated hereby and thereby.  This Agreement
constitutes, and the Related Agreements (when executed and delivered pursuant
hereto for value received) will constitute, the valid and binding agreements
of SMI and each of the Shareholders, respectively, enforceable against SMI
and each of the Shareholders in accordance with their respective terms.

     4.03     No Conflict.  The execution, delivery and performance of this
Agreement by SMI and the Shareholders does not and will not (a) violate,
conflict with or result in the breach of any provision of the Articles of
Incorporation or Bylaws of SMI, (b) conflict with or violate any Law
applicable to SMI or any of the Shareholders or by which any of its assets,
properties or businesses is bound or affected or (c) except as provided on
Item 4.03 of the SMI Disclosure Schedule, conflict with, result in any
breach of, constitute a default (or event which with the giving of notice or
lapse of time, or both, would become a default) under, require any consent
under, or give to others any rights of termination, amendment, acceleration,
suspension revocation or cancellation of, or result in the creation of any
lien, security interest, charge or encumbrance on any of the assets or
properties of SMI pursuant to, any note, bond, mortgage or indenture,
contract, agreement, lease (including any leases with respect to the Leased
Property), sublease, license, permit, franchise or other instrument or
arrangement to which SMI or any of the Shareholders is a party or by which
any of such assets or properties is bound or affected.

     4.04     Capitalization.  The authorized capital stock of SMI consists
of 10,000,000 shares of Common Stock, $.0025 par value, of which 2,000,000
shares are issued and outstanding.  All of the outstanding shares of SMI
Common Stock are owned of record and beneficially by the holders indicated
and in the amounts set forth on Item 4.04 of the SMI Disclosure Schedule.
All such outstanding shares have been duly authorized and validly issued and
are fully paid and non-assessable and free of adverse claims, liens, options,
encumbrances, judgments, or restrictions of any kind, and preemptive or other
rights that entitle or entitled any person to acquire such shares, and no
shares of capital stock are reserved for issuance.  Except as set forth on
Item 4.04 of the SMI Disclosure Schedule, there are no outstanding options,
warrants, rights, calls, subscriptions, commitments, conversion rights,
rights of exchange, plans or other agreements or claims of any character
providing for the purchase, issuance or sale of any shares of the capital
stock of SMI.  Except as provided on Item 4.04 of the SMI Disclosure
Schedule, there are no shares of SMI Common Stock held in the treasury of
SMI.  There are an aggregate of 173,913 Rights (as such term is defined in
the Phantom Stock Plans) issued and outstanding under the Phantom Stock
Plans, each of which Rights has an Initial Value (as such term is defined in
the Phantom Stock Plans) of $69.00.  No shares of SMI Common Stock have been
issued in violation of applicable securities laws.












     4.05     Subsidiaries, Affiliated Companies and Investments.  SMI
does not own, directly or indirectly, of record or beneficially, any capital
stock or other equity or ownership or proprietary interest in any
corporation, partnership, association, trust, joint venture or other entity.

     4.06     Financial Statements.  SMI has heretofore furnished O&M
with (a) the financial statements including the notes thereto as of and for
the twelve months ended April 30, 1992, and the eight months ended December
31, 1992, which statements include the balance sheets as of those dates, and
the related statements of income, shareholders' equity and cash flows for the
periods then ended, as audited by E&Y and (b) the unaudited balance sheet of
SMI as of October 31, 1993 (the "SMI Current Balance Sheet"), together
with the related statement of income for the ten months then ended (all such
financial statements being referred to collectively as the "SMI Financial
Statements").  The SMI Financial Statements have been prepared in accordance
with GAAP (except as may be noted therein and except for the absence of
footnotes with respect to the SMI Current Balance Sheet) and fairly present
the financial condition of SMI at the respective dates thereof and the
results of operations of SMI and changes in its financial position for the
periods indicated (subject, in the case of the SMI Current Balance Sheet, to
normal, recurring year-end audit adjustments that are not in the aggregate
material).

     4.07     No Material Adverse Changes.  Since December 31, 1992,
the business of SMI has been operated in the ordinary course and there has
been no change (and to the Knowledge of SMI and the Shareholders, no fact or
condition exists or is contemplated or threatened which might cause such a
change in the future) in the assets or liabilities, or in the business or
condition, financial or otherwise, or in the results of operations or
prospects, of SMI, which individually or in the aggregate, have had a
material adverse effect on the business prospects, properties or condition,
financial or otherwise, of SMI; provided, however, that any deterioration in
SMI's condition (financial or otherwise) or relationships with customers
(other than VHA) or employees resulting from (i) SMI's announcement of the
transactions contemplated hereby or (ii) business or personnel policies or
actions (e.g., terminations) which O&M Holding may implement with respect to
SMI following the Effective Time shall not constitute a material adverse
change for these purposes (or for purposes of Section 8.02 hereof).  Without
limiting the foregoing, except as set forth on Item 4.07 of the SMI
Disclosure Schedule, since December 31, 1992, there has not been:

          (a)  any loss, damage, destruction or other casualty materially and
adversely affecting the business prospects, properties, assets or business of
SMI (whether or not covered by insurance);

          (b)  (i) any increase made or agreed to in the compensation
(including, without limitation, any increase pursuant to any pension, profit

compensation after such increase was in excess of $100,000 per annum other
than to the persons listed on Item 4.16 of the SMI Disclosure Schedule, (ii)
any bonus, percentage compensation, service award or other like benefit
having a value in excess of $25,000 granted, made, agreed to or accrued to
the credit of any such director, officer, agent, consultant or employee other
than to the persons listed on Item 4.16 of the SMI Disclosure Schedule, or











(iii) any welfare, pension, retirement or similar payment or arrangement made
or agreed to by SMI for the benefit of any such director, officer, agent,
consultant or employee other than to the persons listed on Item 4.16 of the
SMI Disclosure Schedule;

          (c)  any change in any method of accounting or accounting practice
of SMI;

          (d)  any notes or accounts receivable or portions thereof written
off by SMI as uncollectible, if such write offs were either in excess of the
bad debt reserve established therefor in the SMI Current Balance Sheet or
incurred other than in the ordinary course of business;

          (e)  any issuance or sale of any stock, bonds or other corporate
securities of which SMI is the issuer, or the grant or issuance of any stock
options, warrants, or other rights to purchase securities of SMI;

          (f)  any direct or indirect redemption, purchase or other
acquisition by SMI of any shares of capital stock of SMI;

          (g)  any declaration, setting aside or payment of any dividend or
distribution (direct or indirect, whether in cash or property, and whether
characterized as salary, bonus, dividend or otherwise) other than
distributions totaling $3,838,000;

          (h)  any discharge or satisfaction of any lien or encumbrance or
payment or satisfaction of any obligation or liability (whether absolute,

current liabilities incurred since the date of the SMI Current Balance Sheet
in the ordinary course of business and consistent with past practice, and (z)

of SMI, cancellation of any debts or claims or waiver of any rights of

and consistent with past practice;

          (j)  any assumption, guarantee or endorsement by SMI of the
obligations of any other individual or entity or any loans or advances to any
individual or entity except in the normal course of business;

          (k)  any sale, assignment or transfer of any patents, trademarks,
trade names, copyrights or other similar assets, including applications or
licenses therefor;

          (l)  any capital expenditures, or commitment to make any capital
expenditures, for additions to property, plant or equipment, not in the

corporate officers or directors, or any affiliate or associate of any such
person, has any direct or indirect ownership interest other than the
transactions listed on Item 4.19 of the SMI Disclosure Schedule;

          (n)  any material deterioration of relations between SMI and its
customers considered as a whole, including but not limited to the loss, or to
the Knowledge of SMI and the Shareholders, any threatened loss of VHA;

          (p)  any other transaction other than in the ordinary course of

SMI or to which SMI now contributes or has contributed on behalf of its
employees or the employees of an ERISA Affiliate.  Except as provided in Item

All reports, returns and other documentation that are required to have been
filed with the Internal Revenue Service, the Department of Labor, the PBGC or
any other governmental agency (federal, state or local) with respect to the
employee plans have been filed on a timely basis.  Except as set forth in
Item 4.17 of the SMI Disclosure Schedule, no claims or complaints to or by
any person or governmental entity have been filed or, to the knowledge of SMI
and each of the Shareholders, are contemplated or threatened, with respect to
any employee plan.

contributed to or maintained a "multiemployer plan" (as defined in Section
3(37) of ERISA).

          (f)  Except as required by Section 601 of ERISA and Section 4980B

in oral or written form) to any employee or former employee that such
benefits would be provided.  The execution of and performance of the
transactions contemplated in this Agreement and the Related Agreements will
not (either alone or upon the occurrence of any additional or subsequent
events) constitute an event of default under any benefit plan, policy,
arrangement or agreement or any trust or loan that will or may result in any
payment, acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits or obligation to fund benefits with respect to any
employee.

material labor difficulty during the three years immediately preceding the

asserted under CERCLA, RCRA, the Clean Air Act, the Clean Water Act or any
other federal, state or local environmental statute, regulation, policy,

December 31, 1992 and in O&M's Quarterly Report on Form 10-Q for the
quarterly period ended September 30, 1993 (the "O&M Financial Statements") as
filed with the SEC, were prepared in accordance with GAAP, except as may be
noted therein, and fairly present the financial condition of O&M at the
respective dates thereof and the results of operations of O&M for the periods
indicated (subject, in the case of unaudited financial statements to normal,
recurring year-end adjustments that are not in the aggregate material.)

     5.07     No Changes.  Since September 30, 1993, the business of O&M and
the O&M Subsidiaries has been operated in the ordinary course consistent with
past practice, and there has not been (and to the Knowledge of O&M, no fact
or condition exists or is contemplated or threatened which might cause such
change in the future) (a) any material adverse change in the operations,
properties or condition (financial or otherwise) of O&M and the O&M
Subsidiaries or (b) any other change in the nature of, or in the manner of
conducting, the business of O&M and the O&M Subsidiaries, other than changes
which neither have had, nor reasonably may be expected to have, a material
adverse effect on the business of O&M and the O&M Subsidiaries considered as
a whole.

     5.08     Books and Records.  The books of accounts and records of O&M
are true, complete and correct in all material respects.

     5.09     Governmental Authorization.  The execution, delivery and
performance by O&M and O&M Holding of this Agreement and the consummation of











the transactions contemplated hereby by O&M and O&M Holding, require no
action by or in respect of, or filing with, any governmental body, agency,
official or authority other than fillings required to be made under the HSR
Act, filings required to be made under applicable federal and state
securities laws and filing of the O&M Articles of Exchange in connection with
the O&M Exchange.

     5.10 Litigation.  There is no action, suit, proceeding, claim or
investigation pending, or, to the Knowledge of O&M, threatened against or
affecting O&M or O&M Holding which could materially and adversely affect O&M
or which in any manner challenges or seeks to prevent, enjoin, alter or delay
any of the transactions contemplated by this Agreement; to the Knowledge of
O&M, there is no valid basis for any such action, proceeding or
investigation.  Item 5.10 of the O&M Disclosure Schedule sets forth each
pending action, suit, proceeding, claim or investigation to which O&M or O&M
Holding is a party, as well as the forum, parties thereto, a brief
description of the subject matter thereof and the amount of damages claimed.
O&M Holding is not subject to any order, judgment, decree or obligation of

indebtedness, contingent or otherwise, except as set forth in the O&M
Financial Statements, other than liabilities incurred subsequent to September
30, 1993, in the ordinary course of business and consistent with past
practices.  O&M is not in default in respect of the terms or conditions of
any indebtedness, regardless of whether O&M has received notice of the
existence of any such default.

Disclosure Schedule, O&M is in compliance in all material respects with all
Laws applicable to its operations.  O&M holds all licenses, certificates and
permits from all regulatory authorities that are material to the conduct of
its business, all of which are valid and in full force and effect.

     5.13 Disclosure.  Neither this Agreement nor the O&M Financial
Statements contains any untrue statement of a material fact or omits to state
a material fact necessary in order to make the statements contained herein or
therein, in light of the circumstances under which they are made, not
misleading.  To the Knowledge of O&M, there is no fact which materially and
adversely affects or could affect the business, prospects or financial
condition of O&M or O&M Holding or their respective properties or assets,
which has not been described in this Agreement, the SEC Reports or the O&M
Financial Statements.

     5.14 Securities Reports.  O&M has filed, and delivered to SMI complete

(whether annual or special), (d) all Current Reports on Form 8-K, (e) all

required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading.

     5.15 Broker's or Finder's Fees.  No agent, broker, person or firm acting

this Agreement except that O&M has retained J. P. Morgan as its financial

                        Pending the Effective Time

     6.01     Access to Information Concerning Properties and Records

documents and information concerning the business, operations, properties and
affairs of O&M that SMI or its representatives or of SMI that O&M and its
representatives may reasonably request.  SMI, the Shareholders and O&M agree
to jointly plan and conduct such due diligence in a manner reasonably
believed not to adversely affect the relationship and good will of the
employees, customers, vendors and other business partners of SMI and O&M.
Notwithstanding the foregoing, SMI and O&M may restrict the access of the
other to certain commercially sensitive information with respect to pricing,
margins and contractual terms with specific vendors and customers prior to
expiration of the waiting period (and any extensions thereof) under the HSR
Act, provided that reasonable arrangements shall be made for the conduct of
the review of such information promptly following such expiration and the

Statement/Prospectus.

     6.02     Obligations Concerning Confidentiality.

          (a)  SMI, the Shareholders and O&M and O&M Holding will treat all
such information obtained from the other in strict confidence and will take
all necessary or appropriate actions to prevent disclosure of such
confidential information to third parties without the prior consent of the
other party and will use all reasonable efforts to cause their Affiliates and
advisors to keep such information confidential; provided, however, that:  (i)
any of such information obtained by a party hereto may be disclosed to the
directors, officers, employees, representatives, advisors and Affiliates of
such party solely in connection with this Agreement and the transactions
contemplated hereby (it being understood that such directors, officers,
employees, representatives and advisors shall be informed by such party of
the confidential nature of such information and shall be directed by such











party to treat such information confidentially); and (ii) any of such
information may be disclosed as, in the opinion of counsel to O&M, is
required to be disclosed in the Proxy Statement/Prospectus or in any report
or other filing made by O&M under the Securities Act or the Exchange Act or,
in the reasonable judgment of O&M, is necessary to be disclosed in connection
with obtaining the financing described in Section 8.14.  The foregoing shall
not apply to any party with respect to information which:

                    (i)  was at the time of disclosure generally available to
               the public, other than by breach of this provision;

                    (ii) was in the possession of such party prior to
               disclosure by the other party;

                    (iii)     after such disclosure was acquired in good
               faith from a third party, who did not obtain it directly or
               indirectly from SMI, O&M, or any agent of any such party
               unlawfully; or

                    (iv) was developed independently within the organization
               of SMI or O&M, as the case may be, by personnel not having
               access to such information.

          (b)  Notwithstanding anything in paragraph (a) of this Section
6.02, confidential information may be disclosed, if and only to the extent
legally required, in response to legal process or applicable governmental
regulations, provided that the party obligated to disclose such information
first notifies the other party of the obligation to disclose such
confidential information and the party so obligated fully cooperates with the
other party in taking such measures as shall be appropriate and to the extent
and in the manner permissible under applicable Law.

          (c)  If this Agreement should terminate for any reason, SMI and the
Shareholders will return to O&M all documents obtained by it or its agents
from O&M, containing non-public information concerning O&M and shall destroy
or cause to be destroyed any copies thereof made for SMI or any of its agents
or employees or the Shareholders, and O&M will return to SMI all documents

          (a)  Each of the Shareholders hereby jointly and severally agrees
to indemnify and hold O&M's Indemnitees harmless from and against, and agrees
to defend promptly O&M's Indemnitees from and reimburse O&M's Indemnitees
for, any and all losses, damages, costs, expenses, liabilities, obligations
and claims of any kind, including, without limitation, reasonable attorneys'
fees and other legal costs and expenses (hereinafter referred to collectively
as "Losses"), that O&M's Indemnitees may at any time suffer or incur, or
become subject to, as a result of or in connection with:  (i) any breach or
inaccuracy of any of the representations and warranties made by SMI or the
Shareholders in or pursuant to this Agreement; (ii) any failure of SMI or any
of the Shareholders to carry out, perform, satisfy and discharge any of its
or his covenants, agreements, undertakings, liabilities or obligations under
this Agreement or the Related Agreements or under any of the documents and
instruments delivered by the Shareholders or SMI pursuant to this Agreement;
(iii) the conduct of the business of SMI at any time before the Effective
Time to the extent such activities result in any loss or liability (including
tax obligations) that is not fully reflected on the Closing Balance Sheet or
(except for the Specialty Litigation) the SMI Disclosure Schedules; provided,
that, with respect to Losses related to the matters disclosed on Item 4.10A
of the SMI Disclosure Schedule, the Shareholders shall indemnify O&M's
Indemnitees for any amount by which the insurance deductible of SMI
applicable to such matter exceeds the deductible, if any, provided for under
O&M's insurance policy applicable to such a matter and in effect at the time
of the occurrence of the event from which such Loss arose; (iv) any Specialty
Litigation and any liability relating to or arising from the sale or other

now) conducted by SMI (whether as an unincorporated division or business
function or as a subsidiary, direct or indirect), including without
limitation Specialty and the former AIP division; (v) any Balance Sheet
Deficiency; (vi) any costs, expenses or other liabilities incurred by SMI,
O&M or O&M Holding resulting from the exercise by any holder of SMI Common

exceed the sum of the cash consideration and the aggregate par value of the
O&M Holding Preferred Stock to which such dissenting shareholder would have
been entitled to pursuant to the SMI Plan of Exchange; (vii) the matter











described on Item 4.10 of the SMI Disclosure Schedule with respect to the SMI
401(k) Plan, including but not limited to any costs of litigation with
respect to such matter and the failure of the SMI 401(k) Plan to qualify and
continue to qualify as a Qualified Pension Plan as a consequence of such
matter described on Item 4.10 of the SMI Disclosure Schedule or as a
consequence of any other matter occurring prior to the Effective Time; (viii)
any obligation under the Phantom Stock Plans in excess of the amount set

that O&M's Indemnitees shall have no right to be indemnified, held harmless
from, defended or reimbursed under Section 9.01(a)(i) unless such right is
asserted (whether or not such Losses have actually been incurred) within 24
months after the Effective Time, except there shall be no time limitation
with respect to the representations set forth in Sections 4.01, 4.02, 4.04
and 4.20 hereof, and the time limit with respect to any matter covered by
Section 4.21 hereof shall be 30 days after the expiration of the applicable

Losses (without regard to any potential tax benefits) for which
indemnification is sought with respect thereto shall exceed $1,000,000 and
then only to the extent and in the amount of such excess.

          (b)  In the event a claim against O&M's Indemnitees arises that is
covered by the indemnity provisions of Section 9.01(a) hereof, notice shall
be given promptly by O&M Holding to the Shareholders' Representative.
Provided that the Shareholders' Representative admits in writing to O&M
Holding that such claim is covered by the indemnity provisions of Section
9.01(a) hereof, the Shareholders' Representative shall have the right to
contest and defend by all appropriate legal proceedings such claim and to
control all settlements (unless O&M Holding agrees to assume the cost of
settlement and to forgo such indemnity) and to select lead counsel to defend
any and all such claims at the sole cost and expense of the Shareholders;
provided, however, that the Shareholders' Representative may not effect any
settlement that could result in any cost, expense or liability to the O&M
Indemnities unless O&M Holding consents in writing to such settlement and the
Shareholders' Representative agrees to indemnify the O&M Indemnitees
therefor.  O&M Holding may select counsel to participate in any defense
assumed by the Shareholders, in which event such counsel shall be at O&M
Holding's own cost and expense.  In connection with any such claim, action or
proceeding, the parties shall cooperate with each other and provide each
other with access to relevant books and records in their possession.

     9.02     O&M's Indemnity.

          (a)  Each of O&M Holding and O&M hereby agrees to indemnify and











hold Shareholders' Indemnitees harmless from and against, and agree to defend
promptly Shareholders' Indemnitees from and reimburse Shareholders'
Indemnitees for, any and all Losses that Shareholders' Indemnitees may at any
time suffer or incur, or become subject to, as a result of or in connection
with:  (i) any breach or inaccuracy of any of the representations and
warranties made by O&M in or pursuant to this Agreement; (ii) any failure by
O&M to carry out, perform, satisfy and discharge any of its covenants,
agreements, undertakings, liabilities or obligations under this Agreement or
the Related Agreements and (iii) the conduct by SMI, O&M or O&M Holding of
the business of SMI after the Effective Time other than with respect to
facts, circumstances or conditions existing as of the Effective Time;
provided, however, that Shareholders' Indemnitees shall have no right to be
indemnified, held harmless from, defended or reimbursed under Section
9.02(a)(i) unless such right is asserted (whether or not such Losses have
actually been incurred) within 24 months after the Effective Time, except
there shall be no time limitation with respect to the representations set
forth in Sections 5.01 and 5.02 hereof.  Notwithstanding the foregoing, O&M
and O&M Holding shall not be required to indemnify Shareholders' Indemnitees
under this Section 9.02 unless and until the amount of all Losses (without
regard to any potential tax benefits) for which indemnification is sought
with respect thereto shall exceed $1,000,000 and then only to the extent and
in the amount of such excess.

         (b)  In the event a claim against Shareholders' Indemnitees arises
that is covered by the indemnity provisions of Section 9.02(a) hereof, notice
shall be given promptly by the Shareholders' Representative to O&M Holding.
Provided that O&M Holding admits in writing to the Shareholders'
Representative that such claim is covered by the indemnity provisions of
Section 9.02(a) hereof, O&M Holding shall have the right to contest and
defend by all appropriate legal proceedings such claim and to control all
settlements (unless the Shareholders' Representative agrees to assume the
cost of settlement and to forgo such indemnity) and to select lead counsel to
defend any and all such claims at the sole cost and expense of O&M Holding;
provided, however, that O&M Holding may not effect any settlement that could
result in any cost, expense or liability to the Shareholders unless the
Shareholders' Representative consents in writing to such settlement and O&M
Holding agrees to indemnify the Shareholders therefor.  The Shareholders'
Representative may select counsel to participate on behalf of the
Shareholders in any defense assumed by O&M Holding, in which event the
Shareholders' counsel shall be at their own cost and expense.  In connection
with any such claim, action or proceeding, the parties shall cooperate with
each other and provide each other with access to relevant books and records
in their possession.

         9.03     Acquisition for Investment; Transfer Limitations.  Each of the
Shareholders represents and warrants to O&M Holding that he is an "accredited
investor", as defined in Rule 501 under the Securities Act, his respective
shares of O&M Holding Preferred Stock are being acquired in the SMI Exchange
for investment purposes and not with a view toward any resale or any
distribution thereof.  No Shareholder may Transfer shares of the O&M Holding
Preferred Stock; provided, however, a Shareholder may Transfer O&M Holding
Preferred Stock (a) by a gift, (b) by descent or distribution, (c) to
beneficiaries pursuant to a trust existing as of the date hereof and (d) to
a Shareholder if, in any such case, the transferee (other than a charitable
institution holding less than 1% of the O&M Holding Common Stock) expressly











agrees in writing to be bound by the terms of Sections 9.03, 9.04, 9.05 and
9.06 hereof.  Each Shareholder may only Transfer shares of O&M Holding Common
Stock in compliance with this Section and Section 9.04 hereof and the
Securities Act.  Each Shareholder acknowledges that the shares of O&M Holding
Preferred Stock (and the shares of O&M Holding Common Stock received upon
conversion thereof) will be issued pursuant to an exemption from registration
under the Securities Act, and the certificates representing such shares will
bear a legend indicating that they have not been registered under the
Securities Act and may not be Transferred by such Shareholder, except, in the
case of the O&M Holding Common Stock, in compliance with this Agreement and
pursuant to an effective registration statement or pursuant to an exemption
from registration.  In the event a Shareholder determines to Transfer any
shares of O&M Holding Common Stock pursuant to an exemption from registration
under the Securities Act, such Shareholder will, prior to Transferring such
shares, cause counsel selected by such Shareholder but satisfactory to O&M
Holding to deliver an opinion to O&M Holding to the effect that the Transfer
of such shares is exempt from the registration provisions of the Securities
Act or, in the case of a transfer permitted by Rule 144, such Shareholder
will provide evidence satisfactory to O&M Holding that the Transfer of such
shares is exempt from the registration provisions of the Securities Act.

         9.04     Right of First Refusal.

              (a)  In the event that any Shareholder desires to Transfer to any
third party any shares of O&M Holding Common Stock as permitted by Section
9.03 hereof, he shall give O&M Holding notice ("Notice of Transfer") of his
bona fide intent to sell such shares of O&M Holding Common Stock, specifying
(i) the number of shares to be Transferred, (ii) the prospective purchasers
thereof, (iii) the minimum price and other terms and conditions of such
Transfer, and offering to Transfer such shares of O&M Holding Common Stock to
O&M or its designee(s) at such minimum price and on such terms and
conditions.  The Notice of Transfer shall be accompanied by a copy of the
offer from such third party.

              (b)  If O&M Holding or its designee(s) shall not within 30 days
after receipt of the Notice of Transfer accept such offer in writing with
respect to all the shares of O&M Holding Common Stock specified in such
notice, then, subject to the provisions of paragraphs (c) and (e) hereof,
such Shareholder may Transfer such shares to the prospective purchasers
specified in such Notice of Transfer at a price equal to or above the minimum
price  and on other terms and conditions no less favorable to such
Shareholder than those specified in the Notice of Transfer, at any time
within 60 days of the expiration of such 30-day period, but not otherwise.

              (c)  If such Shareholder shall not have consummated the proposed
Transfer within 60 days after the expiration of the 30-day period referred to
in paragraph (b) above, then he may not Transfer such shares of O&M Holding
Common Stock without again complying with the provisions of this Section
9.04.

              (d)  If O&M Holding or its designee(s) shall accept such offer
within 30 days after the receipt of the Notice of Transfer pursuant to
paragraph (b) above, then O&M Holding or its designee(s) shall purchase the
shares of O&M Holding Common Stock specified in such notice as promptly as is
reasonably practicable, but in no event later than 60 days following such











acceptance.

              (e)  Notwithstanding any other provision in this Section 9.04,
each
Shareholder agrees that he will not, without the prior written consent of O&M
Holding, knowingly Transfer any shares of O&M Holding Common Stock to a
competitor of O&M Holding (including any officer, director, employee,
shareholder or Affiliate of such competitor) or to any person (including such
person's Affiliates and any person or entity which is, to his Knowledge after
inquiry of O&M Holding, part of any group which includes such transferee or
any of its Affiliates) that, after giving effect to such Transfer, would
beneficially own 5% or more of the issued and outstanding shares of O&M
Holding Common Stock unless the transferee agrees to be bound by Sections
9.03, 9.04, 9.05 and 9.06 hereof.

              (f)  Notwithstanding any provision to the contrary in this Section
9.04, a Shareholder may Transfer O&M Holding Common Stock without complying
with the provisions of this Section 9.04 (i) by a gift, (ii) by descent or
distribution, (iii) to beneficiaries pursuant to a trust existing as of the
date hereof, or (iv) to a Shareholder; provided, that, in any such case, the
transferee (other than a charitable institution holding less than 1% of the
O&M Holding Common Stock) expressly agrees in writing to be bound by the
terms of Sections 9.03, 9.04, 9.05 and 9.06 hereof and O&M is given prior
written notice of such Transfer.

         9.05     Standstill.  Each Shareholder agrees that so long as (i) he
owns any shares of O&M Holding Preferred Stock or (ii) the Shareholders,
collectively with their respective Affiliates, own 5% or more of the issued
and outstanding shares of O&M Holding Common Stock, without the prior written
consent of O&M Holding, he will not and will cause his Affiliates not to:

              (a)  acquire, offer to acquire or agree to acquire, directly or
indirectly, by purchase or otherwise, or initiate contact with any person
with the intent to advise, encourage or assist such or any other person to
purchase or acquire in any manner shares of any class of capital stock of O&M
Holding ("O&M Holding Capital Stock"), or participate with or provide
assistance to any person in the purchase or other acquisition of O&M Holding
Capital Stock;

              (b)  form, join or in any way participate in a "group" within the
meaning of Section 13(d)(3) of the Exchange Act with respect to O&M Holding
Capital Stock, except insofar as such group consists solely of the
Shareholders;

              (c)  "solicit" proxies with respect to O&M Holding Capital Stock
under any circumstance; or become a "participant" by taking a position
contrary to that of the Board of Directors of O&M Holding in any contest
relating to the election of directors of O&M Holding or any other matters
submitted to shareholders at an annual meeting or any special meeting (as
such defined terms are used in Regulation 14A under the Act); a Shareholder
shall be deemed to "solicit" or to be such a "participant" if he counsels or
advises or otherwise provides assistance to any person who undertakes or
makes such a "solicitation" or is such a "participant," but shall not, in any
event, be deemed to "solicit" or to be such a "participant" by reason of
exercise of his voting rights with respect to O&M Holding Capital Stock;












              (d)  deposit any O&M Holding Capital Stock, or any securities
convertible into O&M Holding Capital Stock, in a voting trust, or subject any
O&M Holding Capital Stock, or any securities convertible into O&M Holding
Capital Stock, to a voting or similar agreement, other than as required by
Section 9.06 hereof;

              (e)  directly or indirectly offer, sell, transfer, pledge or
otherwise dispose of or encumber any O&M Holding Capital Stock, or any
securities convertible into O&M Holding Capital Stock except, subject (in the
cases described in clauses (i) and (ii) below) to prior compliance with the
provisions of Section 9.04 hereof:

                   (i) sales of O&M HoldingCapital Stock pursuant to an
              underwritten distribution to the public, registered under the
              Securities Act, in which the Shareholders use their best efforts
              and direct the underwriters to use their best efforts to effect as
              wide a distribution of such O&M Holding Capital Stock as
              reasonably practicable and to prevent any one person or group from

              transactions pursuant to Rule 144 of the General Rules and
              Regulations under the Securities Act (provided that any such sale
              is in compliance with the requirements of paragraphs (c)(d)(e)(f)
              and (g) of such rule notwithstanding the provisions of paragraph

              lender acknowledges in writing that it has received a copy of this
              Agreement and agrees that prior to making any offer to sell, sale,
              transfer or other disposition of such O&M Holding Capital Stock,
              whether upon foreclosure of such pledge or security interest or
              otherwise, such lender will give O&M the opportunity to purchase
              such O&M Holding Capital Stock in the manner specified in Section
              9.04 hereof; or

                   (iv)  sales of O&M Holding Capital Stock to O&M Holding or to

or give encouragement to any other person to initiate, commence or propose,
any tender or exchange offer for O&M Holding Capital Stock or any "affiliated
transaction" (as that term is defined in Section 13.1-725 of the Code of
Virginia, as in effect on the date of this Agreement, but with the phrase
"any other Person" substituted for the phrase "any interested shareholder").












         9.06     Voting Agreement.  Each Shareholder agrees that, so long as
(a) he owns any shares of O&M Holding Preferred Stock or (b) the
Shareholders, collectively with their respective Affiliates, own 5% or more
of the issued and outstanding shares of O&M Holding Common Stock, he shall
vote all shares of O&M Holding Preferred Stock or O&M Holding Common Stock,
as the case may be, with respect to each matter to be voted upon by the
holders of such shares, in the same proportion as the votes cast on such
matter by all other holders of the O&M Holding Common Stock (excluding for
such purposes shares held by any person or "group" within the meaning of
Section 13(d)(3) of the Exchange Act (other than any employee benefit plan of
O&M Holding, O&M or the O&M Subsidiaries or any person holding shares for or
pursuant to the terms of any such employee benefit plan) which beneficially
owns 5% or more of the issued and outstanding shares of O&M Holding Common
Stock); provided, however, that the provisions of this Section 9.06 shall not
apply with respect to (a) any matter to be voted upon by holders of O&M
Holding Capital Stock that would amend (i) the provisions of the Series B
Preferred Stock or (ii) any other provisions of the Articles of Incorporation
or Bylaws of O&M Holding if such amendment would affect adversely the
relative rights or preferences thereof and (b) the election of any director
who may be elected by the holders of O&M Holding Preferred Stock and any
nominee to the Board of Directors of O&M Holding designated by the
Shareholders' Representative in accordance with Section 9.09 hereof.

         9.07     Noncompetition Covenant.  Each of the Shareholders agrees
that, except for his ownership of shares of O&M Holding Preferred Stock or
O&M Holding Common Stock and without the prior written consent of O&M
Holding, for a period of three years after the Effective Time (the
"Noncompete Period"), he will not, directly or indirectly, either
individually or as an employee, agent, partner, investor, shareholder,
consultant or in any other capacity participate in or have a financial or
other interest in any business in the United States (the "Noncompete Area")
which is competitive with the business conducted by O&M, SMI or the O&M
Subsidiaries as of the Effective Time; provided, however, that the foregoing
shall not preclude the Shareholders or their respective Affiliates from
owning in the aggregate, directly or indirectly, up to 5% of the issued and
outstanding shares of any class of capital stock of a company, the stock of
which is publicly traded on a national securities exchange or in the over-
the-counter market.  The parties acknowledge that the business conducted as
of the date hereof by Specialty is not competitive with the business
conducted by O&M, the O&M Subsidiaries or SMI.

         If a judicial determination is made that any provision of this Section
9.07 constitutes an unreasonable or otherwise unenforceable restriction
against the Shareholders, the provisions of this Section 9.07 shall be
rendered void only to the extent that such judicial determination finds such
provisions to be unreasonable or otherwise unenforceable.  In this regard,
the parties hereto hereby agree that any judicial authority construing this
provision shall be empowered to sever any portion of the Noncompete Area or
any prohibited business activity from the coverage of this Section 9.07 and
to apply the provisions of this Section 9.07 to the remaining portion of the
Noncompete Area or the remaining business activities not so severed by such
judicial authority.

         The Shareholders hereby agree that any remedy at law for any breach of
the provisions contained in this Section 9.07 shall be inadequate and that











O&M Holding shall be entitled to injunctive relief in addition to any other
remedy it might have hereunder.

         The running of the Noncompete Period shall be tolled during, and the
Noncompete Period shall be extended by, any period of time during which any
Shareholder violates the terms of this Section 9.07 as determined by a court
of competent jurisdiction.

         9.08     Tax Returns.

              (a)  O&M Holding and the Shareholders acknowledge that the status
of SMI as an "S corporation" will be terminated by the SMI Exchange, that
SMI's taxable year will end at the close of the day before the Effective Time
(the "Last SMI Year"), that SMI's books shall be closed for income tax
purposes as of the close of the Last SMI Year, and that a new taxable year
for SMI will begin on the date of the Effective Time (the "First C Year").
The Shareholders shall cause to be prepared and timely filed (taking into
account permitted extensions of the due date) all income tax returns of SMI
for the Last SMI Year and, if not filed before the day of the Effective Time,
SMI's preceding taxable year (e.g., IRS Form 1120S, Schedule K-1(1120S) and
state income tax returns).  A photocopy of each such tax return shall be
furnished to O&M Holding at least 30 days before the due date (including any
extensions) for filing the tax return.  The Shareholders' Representative
shall deliver to O&M Holding, with the photocopy of the proposed IRS Form
1120S for the Last SMI Year, a schedule updating the tax basis information
provided by the Shareholders pursuant to Section 8.16(l) hereof.  If O&M
Holding disagrees with the amount or treatment of any item on any such
return, O&M Holding shall notify the Shareholders' Representative, and O&M
Holding and the Shareholders' Representative shall proceed in good faith to
resolve any dispute regarding the return before the due date.  All income tax
returns filed after the date of the Effective Time for taxable years of SMI
beginning before such date shall be based on the same tax accounting methods
and elections as used for its taxable year immediately preceding the year of
such return, except as otherwise required by law or as agreed upon by O&M
Holding and the Shareholders' Representative.

              (b)  The Shareholders, O&M Holding and SMI will cooperate with
each
other to the extent reasonably required to facilitate the preparation and
timely filing of (i) any income tax return of SMI for its Last SMI Year, the
preceding taxable year, or its First C Year and (ii) any tax information
return, report, or statement with respect to the SMI Exchange.

         9.09     Board Nominee.  Commencing when and continuing for so long as
the Shareholders, collectively, have the right to vote at least 5% of the
outstanding shares of O&M Holding Common Stock, O&M Holding will exercise all
authority under applicable law (subject to the fiduciary obligations of the
Board of Directors of O&M Holding to O&M Holding's shareholders) to cause one
nominee designated by the Shareholders' Representative and reasonably
acceptable to the Board to be included in the slate of nominees recommended
by such Board to O&M Holding's shareholders for election as directors at each
annual meeting of shareholders of O&M Holding.

         9.10 Financial Statements.  The Shareholders shall cause E&Y to prepare
and deliver to O&M Holding by February 28, 1994 audited balance sheets as of











December 31, 1993 and 1992 and April 30, 1992 and 1991 and audited statements
of income and cash flow for the year ended December 31, 1993, the fiscal
years ended April 30, 1992 and 1991 and the eight months ended December 31,
1992 and any other financial statements of SMI and Midwest as may be required
by Rule 3-05(b) of Regulation S-X of the SEC audited by E&Y that have not
been delivered previously pursuant to Section 6.09 hereof.

         9.11 Tax Status of Exchanges.  O&M, O&M Holding, SMI and the
Shareholders acknowledge that the Exchanges are intended to qualify as a
transaction described in Section 351 of the Code and that the Exchanges are
intended to be pursuant to a single plan for purposes of Section 351 of the
Code and the regulations thereunder.  O&M, O&M Holding, SMI and the
Shareholders covenant that they will report the Exchanges in accordance with
such intent for federal income tax purposes.

         9.12 Shareholders' Representative.  Each of the Shareholders hereby
appoints C. G. Grefenstette or his designee (as appointed in writing), as the
agent, proxy, and attorney-in-fact for the Shareholders for all purposes
under this Agreement (including without limitation full power and authority
to act on the Shareholders' behalf) (a) to consummate the transactions
contemplated under this Agreement, (b) in the event of such consummation, to
receive on behalf of the Shareholders each of such Shareholder's SMI Exchange
Consideration, (c) to pay in accordance with Section 11.01 hereof the
Shareholders' share of the transaction expenses, (d) to execute and deliver
the Certificates and such further instruments of assignment as O&M Holding
shall reasonably request, (e) to execute and deliver on behalf of the
Shareholders any amendment to this Agreement, provided that such amendment
does not change the definition or manner of calculating the SMI Exchange
Consideration to be received by the holders of the SMI Common Stock or does
not increase the Shareholders' liabilities in any material respect and does
not alter Article IV hereof in a manner adverse to the Shareholders, and (f)
to take all other actions to be taken by or on behalf of the Shareholders and
exercise any and all rights which the Shareholders are permitted or required
to do or exercise under this Agreement.  The Shareholders' Representative
shall not be liable to the Shareholders for any error in judgment for any act
or step taken, or permitted to be taken, in good faith, or for doing anything
in connection herewith, except for his own willful misconduct or gross
negligence.  As between themselves and the Shareholders' Representative, the
Shareholders, jointly and severally, agree to indemnify the Shareholders'
Representative against, and hold the Shareholders' Representative harmless
from, any and all losses, costs, damages, expenses, claims and attorneys'
fees suffered or incurred by the Shareholders' Representative as a result of,
in connection with, or arising from or out of, the acts or omissions of the
Shareholders Representative in performance of, or pursuant to, this
Agreement, except such acts or omissions as may result from the Shareholders'
Representative's willful misconduct or gross negligence.

         9.13 Books and Records.  O&M Holding agrees to cooperate with and make
available to the Shareholders during normal business hours, all books,
records and information relating to SMI that are necessary or useful in
connection with any tax inquiry, audit, investigation or dispute, any
litigation or investigation or any other matter.  The Shareholder(s)
requesting any such books, records, information or employees shall bear all
of the out-of-pocket costs and expenses (including, without limitation,
attorneys' fees, but excluding reimbursement for salaries and employee











benefits) reasonably incurred in connection with providing such books,
records, information or employees.

         9.14 Phantom Stock Plans.  Immediately following the Effective Time,
SMI
shall pay to the participants in the Phantom Stock Plans an aggregate of
$1,800,000 in satisfaction in full of SMI's obligations under such plan.

         9.15 New York Stock Exchange Listing Application.  O&M Holding agrees
to
use its best efforts to cause the shares of O&M Holding Common Stock issuable
upon conversion of the O&M Preferred Stock to be listed on the New York Stock
Exchange.

         9.16 Midwest Accounts Receivable Guarantee.

              (a)  SMI shall have the right, at any time after the 150th day
following the Effective Time, to assign to the Shareholders a face amount of
Midwest Receivables (the "Assigned Receivables") equal to the uncollected
portion of any Midwest Receivable included on the Closing Balance Sheet that
has not been collected by SMI within 150 days after the Effective Time;
provided, however, that prior to such reassignment, SMI shall use reasonable
and customary efforts to collect such Midwest Receivables (which shall not
require SMI to employ commercial collection agencies or file suit).  SMI
shall deliver to the Shareholders' Representative all documents that relate
to the Assigned Receivables and any similar documents generated by SMI after
the Effective Time.  Upon receipt of a document from SMI transferring the
Assigned Receivables to the Shareholders, the Shareholders shall have the
joint and several obligation to promptly pay to SMI the face amount of the
Assigned Receivables (less any reserve for the Midwest Receivables on the
Closing Balance Sheet).  SMI shall cooperate with the Shareholders in any
reasonable collection efforts relating to the Assigned Receivables, including
remitting to the Shareholders' Representative any proceeds received by SMI
with respect to such Assigned Receivables.

              (b)  All payments on the relevant accounts received by SMI during
the period beginning at the Effective Time and ending on the 150th day
following the Effective Time shall be allocated among the Midwest Receivables
and the relevant accounts receivable arising after the Effective Time in the
manner specified in the remittance advice accompanying such payment.  If such
allocation is not so specified in any remittance advice, SMI will contact the
customer and request instructions as to how such payment should be allocated.
If the customer then declines to give such instructions, the amount of such
payment shall be applied against the oldest outstanding invoices.

                     Termination, Amendment and Waiver

O&M Holding;

              (b)  By SMI and the Shareholders, if O&M enters into a definitive
agreement with respect to (i) any acquisition or purchase of assets of, or
any equity interest in, or any exchange offer, merger, consolidation,
business combination, sale of all or substantially all of the assets, sale of
securities, liquidation, dissolution or similar transactions involving O&M,
or (ii) any acquisition by O&M of another corporation or other entity, in any
such case in which the value of the aggregate consideration to be paid would

              (c)  By SMI and the Shareholders, if O&M fails to perform in any
material respect any of its obligations under this Agreement;

              (d)  By SMI and the Shareholders, if there has been a material
breach by O&M of any representation and warranty contained in this Agreement;

              (e)  By O&M and O&M Holding if there has been a material breach by
SMI or the Shareholders of any representation and warranty contained in this
Agreement except to the extent the material breach of such representation or
warranty shall result in the indemnification therefor by the Shareholders
pursuant to Section 9.01(a)(vii);

              (f)  By O&M and O&M Holding, if SMI or any of the Shareholders
fails to perform in any material respect any of its obligations under this

become void and there shall be no liability on the part of SMI, O&M or the
Shareholders except as set forth in Sections 6.02, 10.03 and 11.02.  Nothing
herein shall relieve any party from liability for its breach of this
Agreement, except to the extent that Section 11.02 hereof limits the amount

              (a)  If this Agreement terminates for any reason pursuant to
Section 10.01, no party hereto will utilize the fact that this Agreement has

without limitation the customer, vendor and employee relationships, of the
other.  Each party agrees that, upon any breach of this covenant by either
party, the aggrieved party shall be entitled to injunctive relief as well as
damages.

              (b)  If this Agreement terminates for any reason pursuant to
Section 10.01, for one year after such termination, neither SMI nor O&M nor
any of their respective Affiliates shall solicit for employment any person

employ of the other party.

designated by SMI for such purpose).

         If this Agreement is terminated by O&M or O&M Holding pursuant to
Section 10.01(e) hereof, then SMI shall pay to O&M as liquidated damages

         11.03     Publicity.  Except to the extent otherwise expressly required
by Law, prior to the Effective Time no party hereto shall make or cause to be
made any news release or other public statement, including communications to
employees, suppliers, distributors and customers of SMI or O&M, pertaining to
the matters contemplated by this Agreement unless approved by SMI and O&M,
which approval shall not be unreasonably withheld.  Without limiting the
foregoing, in all announcements, press releases, notices to customers,
vendors, employees and other third parties, and in all other communications
