RECORD DATE
 
    Shareholders of Common Stock of record at the close of business on August
27, 1998 (the "Record Date") are entitled to notice of and to vote on all
matters presented at the Special Meeting. On the Record Date, there were
3,009,395 shares of Common Stock outstanding.
 
VOTING; PROXIES
 
    The presence, either in person or by proxy, of persons entitled to vote a
majority of the outstanding shares of Common Stock is necessary to constitute a
quorum for the transaction of business at the Special Meeting. On each matter to
be considered at the Special Meeting, shareholders will be entitled to cast one
vote for each share of Common Stock held on the Record Date. In order for the
Merger Agreement to be approved and adopted, the votes cast in favor must
constitute at least a majority of the outstanding shares of Common Stock. Due to
this required majority vote, abstentions and failures to vote will have the same
effect as a vote against approval of the Merger Agreement and the Merger.
Pursuant to a shareholders agreement, dated May 19, 1998 (the "Shareholders'
Agreement"), by and among General Electric and certain shareholders of the
Company (the "Committed Shareholders") and subject to the terms and conditions
of such Shareholders' Agreement, the Committed Shareholders have agreed to vote
all of their shares of Common Stock in favor of approval and adoption of the
Merger Agreement and the Merger. As of the Record Date, the Committed
Shareholders held 1,589,279 shares of Common Stock, constituting nearly 53% of
the shares of Common Stock outstanding on such date, which is an amount
sufficient to approve the Merger Agreement at the Special Meeting. See "VOTING
AND PROXIES" AND "DESCRIPTION OF THE PROPOSED MERGER--SHAREHOLDERS' AGREEMENT."
 
    Shareholders are urged, whether or not they expect to attend the Special
Meeting, to complete, sign and date the accompanying proxy card and return it
promptly in the enclosed envelope, which requires no postage if mailed in the
United States. If you return an executed proxy and then attend the Special
Meeting in person, you may allow your proxy to remain in effect, or you may
revoke your proxy and vote in person by giving written notice of such revocation
to the Company's Secretary, or by filing a duly executed proxy bearing a later
date, at any time prior to the time the vote is taken. Attendance at the Special
Meeting will not by itself revoke a proxy.
 
    Unless otherwise directed in the accompanying proxy, the persons named
therein will vote each proxy FOR approval of the Merger Agreement and the
Merger. As to any other business that may properly come before the Special
Meeting, the proxy holders will vote in their discretion. The Company currently
does not know of any other such business.
 
PERSONS MAKING THE SOLICITATION
 
    This solicitation of proxies is being made by the Board. All expenses
associated with soliciting proxies, including the preparation, assembly,
printing and mailing of this Proxy Statement, will be borne by the Company. It
is contemplated that proxies will be solicited principally through the use of
the mail, but officers, directors and employees of the Company may solicit
proxies personally or by telephone or facsimile, without receiving additional
compensation therefor. The Company will reimburse banks, brokerage houses and

continue as of the Effective Date to conduct its business and operations as an
indirect subsidiary of General Electric. See "CERTAIN INFORMATION CONCERNING
GENERAL ELECTRIC AND SUB."
 
THE SPECIAL MEETING
 
    Proxies are being solicited by the Board for use at the Special Meeting to
be held at 8:00 a.m., central daylight time, at the Hilton Arlington Hotel
located at 2401 East Lamar Boulevard, Arlington, Texas 76006, on September 15,
1998, for the purpose of considering and voting upon approval and adoption of
the Merger Agreement and the Merger, as more particularly described herein and
in the Notice of Special Meeting accompanying this Proxy Statement.
 
RECORD DATE; QUORUM
 
    Only holders of record of Common Stock at the close of business on the
Record Date, August 27, 1998, are entitled to notice of and to vote on all
matters presented at the Special Meeting and any adjournments and/or
postponements thereof. The presence, either in person or by proxy, of persons
entitled to vote a majority of the outstanding shares of Common Stock is
necessary to constitute a quorum for the transaction of business at the Special
Meeting. Record holders of Common Stock are entitled to
 
                                       3
<PAGE>
one vote for each share held by them. On the Record Date, there were 3,009,395
shares of Common Stock outstanding. See "VOTING AND PROXIES."
 
VOTE REQUIRED
 
    The affirmative vote of holders of a majority of the outstanding shares of
Common Stock (more than 50%) is required to approve the Merger Agreement and the
Merger. Pursuant to the Shareholders' Agreement, and subject to the terms and
conditions therein, the Committed Shareholders have agreed to vote all of their
shares of Common Stock in favor of approval of the Merger Agreement and the
Merger. As of the Record Date, the Committed Shareholders held 1,589,279 shares
of Common Stock, constituting nearly 53% of the shares of Common Stock
outstanding on such date, which is an amount sufficient to approve the Merger
Agreement and the Merger at the Special Meeting. Ninety-three percent (93%) of
the near 53% of shares held by the Committed Shareholders are held individually
by directors of the Company, their direct family members, or in accounts,
companies and trusts under their voting discretion. Thus, certain directors of
the Company, their direct family members, or accounts, companies and trusts
under their discretion control 49% of the Common Stock outstanding on the Record
Date and they have committed to vote all of their combined Common Stock in favor
of the Merger Agreement and the Merger. See "VOTING AND PROXIES" and
"DESCRIPTION OF THE PROPOSED MERGER--SHAREHOLDERS' AGREEMENT."
 
REASONS FOR THE MERGER
 
    During the past several years the medical equipment service industry has
been characterized by increasing consolidation, with participants in the market
seeking the capability of providing a full range of products and services to
their customers. In addition, consolidation in the medical care industry has
caused an increase in the capital required by companies to compete in the
industry, while enhancing the outlook for larger companies which provide greater
economies of scale. During this period, management of the Company reviewed the
Company's strategic alternatives and took various steps in an effort to maintain
its competitiveness. Despite these efforts, the Company continued to have
unprofitable operating results and liquidity concerns, and continued to lose
market share and its competitive advantages in the marketplace. As a result, in
late 1996, the Company's management and the Board determined that it was in the
best interests of the Company to explore the possibilities of seeking a buyer
for substantially all of the assets or stock of the Company.
 
    At the time the Merger Agreement was negotiated and executed, General
Electric was the only party that had made a qualified offer to purchase either
all of the stock or all of the assets of the Company. The terms of the Merger
were determined through negotiations between the Company and General Electric
following extensive discussions, financial analysis and due diligence. In
reaching its determination on May 15, 1998 to approve and adopt the Merger
Agreement and recommend approval of the Merger Agreement and the Merger to the
Company's shareholders, the Board consulted with the Company's management, as
well as its legal counsel and financial advisors, and considered a number of
factors before unanimously concluding that the Merger represented the best
available alternative to enhance shareholder value. The Board did not find it
practicable to, and did not attempt to, assign relative weights to the specific
factors considered. See "DESCRIPTION OF THE PROPOSED MERGER--BACKGROUND OF AND
REASONS FOR THE MERGER."
 
FAIRNESS OPINION
 
    Warburg Dillon Read LLC ("WDR"), a successor to SBC Warburg Dillon Read
Inc., has delivered to the Board a written opinion as of May 11, 1998 to the
effect that, as of such date, based upon and subject to various considerations
set forth in the opinion, the Per Share Merger Consideration (as hereinafter
defined) is fair, from a financial point of view, to the shareholders of the
Company. At a Board meeting on May 15, 1998, WDR verbally reaffirmed its written
opinion. A copy of the opinion of WDR, which sets forth the assumptions made,
matters considered and the scope of their review, is attached to this Proxy
 
                                       4
<PAGE>
Statement as Appendix II and should be read in its entirety. See "DESCRIPTION OF
THE PROPOSED MERGER-- FAIRNESS OPINION."
 
RECOMMENDATION
 
    Management of the Company and the Board believe that the Merger will benefit
the Company's shareholders and is in the best interests of the Company and its
shareholders. The Board has unanimously approved the Merger Agreement and the
Merger and has unanimously recommended that the Merger Agreement be adopted and
the Merger be approved by the shareholders of the Company. See "DESCRIPTION OF
THE PROPOSED MERGER--RECOMMENDATION."
 
MERGER
 
    Pursuant to the Merger Agreement, the Company and General Electric have
agreed, subject to approval of the shareholders of the Company and the
satisfaction of certain other conditions, that Sub will merge with and into the
Company. At the Effective Date of the Merger, Sub will cease to exist and the
Company will continue as the Surviving Corporation and will be an indirect
subsidiary of General Electric. See "DESCRIPTION OF THE PROPOSED MERGER--THE
MERGER."
 
MERGER CONSIDERATION
 
    PER SHARE MERGER CONSIDERATION
 
    At the Effective Date, each and every outstanding share of Common Stock
(other than shares held by General Electric and InnoServ and their respective
subsidiaries, and Dissenting Shares which have been properly exercised and
perfected) will be converted into (i) the right to receive an amount equal to
(A) the sum of $16,000,000 (the "Merger Consideration") less the MEDIQ Payment
(as hereinafter defined) and less the Escrow Payment (as hereinafter defined),
divided by (B) the number of shares of Common Stock outstanding immediately
prior to the Effective Date (the "Per Share Merger Consideration"), and (ii) the
contingent right to receive additional consideration pursuant to the Escrow
Agreement described below under "ESCROW PAYMENT." As of the Record Date,
3,009,395 shares of Common Stock were outstanding. If the number of shares of
outstanding Common Stock remains the same on the Effective Date, the Per Share
Merger Consideration will be approximately $3.97. See "DESCRIPTION OF THE
PROPOSED MERGER--MERGER CONSIDERATION."
 
    MEDIQ PAYMENT
 
    Pursuant to a stock purchase agreement dated November 13, 1997 (the "MEDIQ
Agreement"), by and among the Company and MEDIQ Incorporated and MEDIQ
Investment Services, Inc. (collectively, "MEDIQ") (a copy of which is attached
hereto as Appendix III), the Company repurchased 2,026,438 shares of the
Company's Common Stock (the "MEDIQ Shares") from MEDIQ in exchange for an
agreement that the Company would not enter into or consummate a change of
control (as defined in the MEDIQ Agreement) unless the other party or parties
thereto agree, as a condition precedent to such transaction, to pay to MEDIQ the
amount that would have been received by MEDIQ in connection with the change of
control transaction if all of the MEDIQ Shares were outstanding and held by
MEDIQ at the effective time of such change of control transaction. The MEDIQ
Agreement further provides that, after April 1, 1998 and through September 30,
1998, the Company shall not enter into or consummate a change of control unless
the other party or parties thereto agree, as a condition precedent to such
transaction, to pay to MEDIQ 50% of the amount that would have been received by
MEDIQ in connection with the change of control transaction if all of the MEDIQ
Shares were outstanding and held by MEDIQ at the effective time of such change
of control transaction.
 
                                       5
<PAGE>
    MEDIQ and the Company are currently in dispute as to the amount that would
be owed to MEDIQ under the terms of the MEDIQ Agreement upon consummation of the
Merger. If the Company and General Electric had entered into or consummated a
change of control on or prior to April 1, 1998, based on the Merger
Consideration, upon consummation of the Merger MEDIQ would have been entitled to
$6,437,994. Pursuant to a letter agreement dated May 19, 1998, among the
Company, MEDIQ and General Electric (the "Letter Agreement"), a copy of which is
attached hereto as Appendix V, MEDIQ has acknowledged that it believes that,
based on the accuracy of the representations described below, it will be owed
$4,052,876 upon consummation of the Merger, while the Company has acknowledged
that it believes that MEDIQ will be owed $3,218,997. The Company's belief is
based on the fact that $3,218,997 is 50% of the amount that MEDIQ would have
been entitled to if the Company and General Electric had entered into or
consummated a change of control on or prior to April 1, 1998. The Merger
Agreement provides for the payment on the Effective Date of the Merger by
General Electric (i) to MEDIQ of an amount equal to $3,218,997 (the "MEDIQ
Payment") and (ii) to the Paying Agent (as hereinafter defined), as escrow
agent, of an amount equal to $833,879, to be held pursuant to an escrow
agreement by and between the Company and MEDIQ in the form attached to the
Merger Agreement.
 
    Under the terms of the Letter Agreement, MEDIQ also released the Company
from any further obligations under the MEDIQ Agreement, contingent upon the
receipt of the MEDIQ Payment and subject to the representations of the Company
and General Electric that such parties did not affirmatively delay any such
change of control transaction and that a description (provided to MEDIQ) of the
parties' discussions with respect to the Merger was materially correct and not
misleading. In connection with the arbitration of the dispute over whether MEDIQ
is owed $4,052,876 or $3,218,997, MEDIQ has advised the Company that it has
concerns as to the accuracy of such representations and that MEDIQ will require
discovery with respect to that issue. MEDIQ has not specified the nature of its
concerns and, in depositions taken in connection with the arbitration
proceedings referenced herein, MEDIQ's Chief Executive Officer and its outside
counsel have testified that they knew of no facts to suggest that the
representations are untrue or that the description is inaccurate. While the
Company believes that the representations are accurate, MEDIQ may nevertheless
claim that they are not accurate and demand that the full amount of $6,437,994
be paid to MEDIQ upon consummation of the Merger. Although the Company believes
that any such claim would be without merit, there is no assurance, if such a
claim is asserted, that the Company will prevail on the issue, whether resolved
in the arbitration proceeding or otherwise; however, the ultimate resolution of
this issue will have no effect on the amount of the Per Share Merger
Consideration nor will it affect the Company's or General Electric's obligations
under the Merger Agreement. See "DESCRIPTION OF THE PROPOSED MERGER--MERGER
CONSIDERATION." It is unlikely that the amount MEDIQ is entitled to receive will
be finally resolved before the Merger is consummated. Should MEDIQ ultimately
obtain a final judgment against the Company that it is owed more than the sum of
the MEDIQ Payment and the Escrow Payment (as hereafter defined), the Company
would be responsible for payment of that excess amount.
 
    ESCROW PAYMENT
 
    As described above, immediately after the Effective Date, General Electric
will deposit $833,879 (the "Escrow Payment") into an account maintained by the
Bank of New York (the "Paying Agent"), and pursuant to the terms of an escrow
agreement by and between MEDIQ, the Committee (as hereinafter defined) and the
Company (the "Escrow Agreement"), the Paying Agent will be instructed to
distribute the Escrow Payment in full to either MEDIQ and/or the holders of
outstanding shares of Common Stock immediately prior to the Effective Date, (or
some combination thereof) in accordance with either an agreement between a
committee representing the former shareholders of the Company (the "Committee")
and MEDIQ regarding such funds, or in the absence of such an agreement, upon the
order of the arbitrator(s) upon completion of the arbitration proceedings
regarding such Escrow Payment.
 
                                       6
<PAGE>
    The Committee will initially consist of Michael Puls, President and Chief
Executive Officer of the Company, Dudley Rauch, Chairman of the Board, and Dr.
Samuel Salen, Vice Chairman and Secretary of the Board. The Committee will
represent the interests of the former shareholders of the Company and will speak
for and on behalf of such shareholders with respect to all matters involving the
Escrow Payment and Escrow Agreement. In the event that the Escrow Payment is
awarded or distributed to the Committee on behalf of the holders of Common Stock
as of the Effective Date, all amounts so distributed shall be payable to such
former holders as follows: each share of Common Stock representing a former
shareholder interest shall be entitled to receive an amount equal to (i) the
amount of Escrow Payment awarded or distributed by the Paying Agent to the
Committee on behalf of the holders of Common Stock as of the Effective Date,
divided by (ii) the number of shares of Common Stock outstanding as of the
Effective Date. As of the Record Date, 3,009,395 shares of Common Stock were
outstanding. If the number of shares of outstanding Common Stock remains the
same on the Effective Date, the holder of each share of Common Stock could
receive an additional $0.277 per share if all of the Escrow Payment is awarded
or distributed to the Committee on behalf of such holders. See "DESCRIPTION OF
THE PROPOSED MERGER--MERGER CONSIDERATION."
 
STOCK OPTIONS
 
    At the Effective Date, all options to purchase shares of Common Stock
("Outstanding Options") shall vest and become effective and exercisable for the
Per Share Merger Consideration. Prior to the Effective Date, each of the holders
of Outstanding Options shall be offered the opportunity to enter into an
agreement with the Company (a "Cancellation Agreement") wherein, upon the
Effective Date, they will receive cash from the Surviving Corporation in an
amount equal to the difference between the Per Share Merger Consideration and
the exercise price of such holder's Outstanding Options in exchange for
cancellation of such holder's Outstanding Options. The holders of such
Outstanding Options will also be entitled to receive from the Surviving
Corporation a per share amount equal to the per share amount, if any, received
by each holder of Common Stock under the Escrow Agreement. See "DESCRIPTION OF
THE PROPOSED MERGER--MERGER CONSIDERATION."
 
PRICE RANGE OF COMMON STOCK
 
    The Common Stock is traded in the Nasdaq National Market. On May 19, 1998,
the last full trading day prior to the public announcement by the Company and
General Electric of the execution of the Merger Agreement, the closing price for
a share of Common Stock in the Nasdaq National Market was $3.25. On May 19,
1998, the high price for a share of Common Stock was $3.25 and the low price for
a share of Common Stock was $3.125. The closing price for a share of Common
Stock on August 24, 1998 was $3.94. See "COMPANY CAPITALIZATION--COMMON STOCK
PRICES AND DIVIDENDS." Shareholders are urged to obtain current market
quotations for the Common Stock.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Certain directors of the Company, their direct family members, or accounts,
companies and trusts under their discretion control 49% of the Common Stock
outstanding as of the Record Date and they have committed, pursuant to the
Shareholders' Agreement, to vote all of their combined Common Stock in favor of
the Merger Agreement. Mr. Puls, the President and Chief Executive Officer of the
Company, and the Company have entered into a bonus agreement, dated December 20,
1996, as amended by a letter agreement dated as of May 15, 1998, wherein Mr.
Puls will receive a bonus of $307,500 upon the consummation of the Merger.
Thomas Hoefert, the Vice President and Chief Financial Officer of the Company,
and the Company have entered into a bonus agreement, dated September 29, 1997,
wherein Mr. Hoefert will receive a bonus of $150,000 upon the consummation of
the Merger. See "DESCRIPTION OF THE PROPOSED MERGER--INTERESTS OF CERTAIN
PERSONS IN THE MERGER."

DISSENTERS' RIGHTS
 
    Record holders of Common Stock who object to the Merger may, under certain
circumstances, and by following the statutorily prescribed procedures set forth
in Chapter 13 of the California General Corporation Law (a copy of which chapter
is attached hereto as Appendix VI), receive cash for the "fair market value" of
their shares, which may be higher or lower than the value of the Per Share
Merger Consideration plus each holder's pro rata portion of the Escrow Payment,
if any. The failure of a dissenting shareholder to follow such procedures may
result in termination or waiver of rights as a dissenter. Since the Common Stock
is traded in the Nasdaq National Market, shareholders of the Company who object
to the Merger may vote against the Merger at the Special Meeting and will be
entitled to dissenters' rights if the Merger is consummated over their
objections, if the holders of five percent or more of the Common Stock make
appropriate demands under Chapter 13 of the California General Corporation Law.
A shareholder must vote against the Merger in order to obtain dissenters' rights
under California law. See "RIGHTS OF DISSENTING SHAREHOLDERS."
 
MANNER OF CONVERTING SHARES
 
    On the Effective Date, each certificate formerly representing shares of
Common Stock (other than shares held by General Electric and InnoServ and their
respective subsidiaries, and Dissenting Shares which have been properly
exercised and perfected) will, automatically without any action on the part of
the holder thereof, be deemed to represent only a certificate (a "Certificate")
entitled to the right to receive the Per Share Merger Consideration and the pro
rata portion of the Escrow Payment. On or as soon as practicable after the
Effective Date, a letter of instructions (the "Letter of Transmittal") setting
forth the manner of exchanging Certificates for the Per Share Merger
Consideration will be delivered by the Paying Agent to each holder of Common
Stock as determined immediately prior to the Effective Date. Upon surrender to
the Paying Agent of the Certificate(s) representing the shares of Common Stock,
together with a properly completed Letter of Transmittal, the holder of such
Certificate(s) shall be entitled to immediately receive the Per Share Merger
Consideration with respect to each share represented by such Certificate(s) and
upon distribution of the Escrow Payment to the Committee, the pro rata portion
of the Escrow Payment, if any. See "DESCRIPTION OF THE PROPOSED MERGER--MANNER
OF CONVERTING SHARES."
 
CONDITIONS TO THE MERGER
 
    The obligations of the Company and General Electric to consummate the Merger
are subject to fulfillment or waiver of the following conditions: (i) approval
of the Merger Agreement by the shareholders of the Company; (ii) the expiration
or termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act") and the absence of any order by any
governmental entity restraining, enjoining or prohibiting the Merger; (iii) the
performance in all material aspects of the agreements of each party,
respectively, under the Merger Agreement and the receipt by each party of
certificates from an officer of the other party to such effect; (iv) the
representations and warranties contained in the Merger Agreement of each party,
respectively, being correct and true as of the Effective Date (except where the
failure to be so true, individually or in the aggregate with other such
failures, would not have a Parent Material Adverse Effect or a Company Material
Adverse Effect, respectively, as such terms are defined in the Merger
Agreement), and the receipt by each party of certificates from an officer of the
other party to such effect; and (v) the receipt by General Electric of an
opinion of counsel of the Company. See "DESCRIPTION OF THE PROPOSED
MERGER--CONDITIONS TO THE MERGER."
 
REGULATORY APPROVAL
 
    General Electric and the Company filed notification and report forms with
the United States Department of Justice (the "DOJ") and the Federal Trade
Commission (the "FTC") seeking early termination of the waiting period under the
HSR Act on December 24, 1997 and December 30, 1997, respectively. On July 14,
1998, General Electric and the Company received written notice that the FTC has
 
                                       8
<PAGE>
granted early termination of the waiting period under the HSR Act. Pursuant to
the terms of the Merger Agreement, General Electric and the Company entered into
a side agreement, dated May 19, 1998 (the "Side Agreement"), wherein General
Electric agreed to pay the Company $1,200,000 if the DOJ did not grant early
termination or expiration of the waiting period under the HSR Act prior to the
later of (i) June 22, 1998 or (ii) the date of the meeting of the shareholders
of the Company at which the Merger is approved. Since early termination has been
granted, no amount is payable by General Electric to the Company under the Side
Agreement. See "DESCRIPTION OF THE PROPOSED MERGER--REGULATORY APPROVALS" and
"--BACKGROUND OF AND REASONS FOR THE MERGER."
 
AMENDMENT; TERMINATION
 
    The Merger Agreement may be amended by written agreement of each of the
parties before or after approval by the Company's shareholders by action of each
party's board of directors (in the case of the Company and Sub) and by any vice
president (in the case of General Electric), provided that, if after such
shareholder approval, if applicable law requires shareholder approval of an
amendment, the amendment will not be valid without such approval. The Merger
Agreement may be terminated and the Merger abandoned before the Effective Date
(i) by mutual written consent of the Company, duly authorized by its Board, and
General Electric by any vice president; (ii) by either party if the other fails
to comply in any material respect with any of its respective covenants or
agreements contained in the Merger Agreement, provided that the other party is
not in material breach of any representation, warranty, covenant or other
agreement contained in the Merger Agreement; (iii) by either party if there has
been a material breach at the time when made by the other party, provided that
the terminating party is not in material breach of any representation, warranty,
covenant or other agreement contained in the Merger Agreement; (iv) by either
party if the shareholders of the Company shall not approve the Merger at the
Special Meeting; (v) by either party if the Merger has not been effected on or
prior to the close of business on September 30, 1998, except that such right to
terminate shall not be available to a party whose willful and material failure
to fulfill any obligation of the Merger Agreement has been the cause of, or
resulted in, the failure of the Merger to be effected; (vi) by either party if
any court or other governmental entity shall have issued an order, decree or
ruling or taken any other action permanently enjoining, restraining or otherwise
prohibiting the transactions contemplated by the Merger Agreement; (vii) by
either party if any order or directive has a material adverse effect on the
business, operations or financial condition of the Company as the Surviving
Corporation; (viii) by the Company by written notice to General Electric if the
Board in good faith determines that a proposal by a third party to purchase 35%
or more of the assets of the Company, or which results in such third party
controlling 35% or more of the beneficial interests of shares of the Company's
Common Stock, will be more favorable to its shareholders than the Merger and
General Electric has not exercised its right to match such proposal; or (ix) by
General Electric if the Board shall have failed to recommend the Merger to the
Company's shareholders, or shall have modified in a manner adverse to General
Electric or withdrawn its recommendation of the Merger to the Company's
shareholders as being advisable and fair to and in the best interests of the
Company and its shareholders. If a termination is caused by (i) a breach of a
representation or warranty of the Company; (ii) a failure by the Company to
comply in any material respect with any of its covenants or agreements contained
in the Merger Agreement; (iii) a failure by the shareholders to vote in favor of
the Merger; (iv) notification to General Electric of the Board's determination
that a third party's proposal is more favorable than the Merger; or (v) failure

PREFERRED STOCK
 
    Pursuant to the Merger Agreement, on June 5, 1998, a subsidiary of General
Electric purchased 700,000 shares of Series B Preferred Stock of the Company
(the "Preferred Shares") from the Company for $2,800,000. Except as otherwise
expressly provided by law, the Preferred Shares do not have any right to vote
for the election of directors or for any other purpose (including the Merger).
The Preferred Shares accrue dividends of $0.32 per share per annum, beginning
six months from the issuance of such shares, whether or not earned or declared,
and are redeemable by the Company at any time at a price equal to $4.00 per
share plus any accrued but unpaid dividends. Each Preferred Share is also
convertible into Common Stock, at the option of the holders, at any time after
the earlier of (i) the consummation of a reorganization (which includes mergers,
consolidations and acquisitions of more than 35% of the Common Stock) of the
Company with a third party or (ii) the later of (A) September 30, 1998 or (B)
the termination of the Merger Agreement. See "DESCRIPTION OF THE PROPOSED
MERGER--PREFERRED STOCK."
 
EFFECTIVE DATE
 
    The proposed Merger will be consummated if and on such date (the "Effective
Date") as the Agreement of Merger of Sub into the Company, attached as Exhibit
A.1 to the Merger Agreement, and appropriate officers' certificates are filed
with and accepted by the California Secretary of State. The Effective Date is
currently expected to occur on or shortly after September 15, 1998, the date of
the Special Meeting, subject to the satisfaction or waiver of the conditions to
the Merger. See "DESCRIPTION OF THE PROPOSED MERGER--THE MERGER" and
"--CONDITIONS TO THE MERGER."
 
FINANCING THE MERGER

    The Merger will be accounted for under the "purchase" method of accounting,
in accordance with generally accepted accounting principles. See "DESCRIPTION OF
THE PROPOSED MERGER--ACCOUNTING TREATMENT."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The exchange by shareholders of their shares of Common Stock for cash and
the right to the Escrow Payment pursuant to the Merger will be a taxable
transaction for federal income tax purposes and may also be a taxable
transaction for state, local, foreign and other tax purposes. See "CERTAIN
FEDERAL INCOME TAX CONSEQUENCES." Shareholders are urged to consult their own
tax advisors with respect to the federal, state, local and other tax

                               VOTING AND PROXIES
 
    As of August 27, 1998, the Record Date for the determination of the
shareholders of the Company entitled to notice of, and to vote at, the Special
Meeting, there were 3,009,395 shares of Common Stock outstanding, which were
held of record by a total of approximately 850 shareholders. Each share entitles
the holder to one vote on each matter to come before the Special Meeting.
 
    The presence in person or by proxy of the holders of a majority of the
outstanding shares of Common Stock is necessary to constitute a quorum for
purposes of the transaction of business at the Special Meeting. The affirmative
vote of the holders of a majority of the outstanding shares of Common Stock is
required to approve and adopt the Merger Agreement and the Merger. Abstentions
and failures to vote will not be counted as votes either in favor of or against
approval of the Merger Agreement and the Merger. However, because approval of
the Merger Agreement requires the affirmative vote of a majority of the
outstanding shares of Common Stock, a shareholder who fails to return a proxy or
otherwise to vote or who abstains from voting on the Merger Agreement will have
effectively voted against the proposal for purposes of determining the number of
votes needed for approval.
 
    Pursuant to the Shareholders' Agreement and subject to the terms and
conditions therein, the Committed Shareholders have agreed to vote all of their
shares of Common Stock in favor of approval and adoption of the Merger Agreement
and the Merger. As of the Record Date, the Committed Shareholders held 1,589,279
shares of Common Stock, constituting nearly 53% of the shares of Common Stock
outstanding on such date, which is an amount sufficient to approve the Merger
Agreement and the Merger at the Special Meeting. Pursuant to the terms of the
Shareholders' Agreement, the Committed Shareholders agreed, until the
termination of the Shareholders' Agreement, to (i) attend the Special Meeting
and vote their shares of Common Stock in favor of the Merger; (ii) vote against
any other third party proposal; (iii) not divest of any such shares of Common
Stock; and (iv) not take any action as a shareholder to solicit a third party
proposal with respect to the purchase or combination of the assets or stock of
the Company. The Shareholders' Agreement terminates upon a termination of the
Merger Agreement; however, if the Merger Agreement is terminated as a result of
the shareholders of the Company voting against the Merger, the provisions of the
Shareholders' Agreement listed above shall survive for six months after such
termination.
 
    Ninety-three percent (93%) of the near 53% of shares held by the Committed
Shareholders are held individually by directors of the Company, their direct
family members, or in accounts, companies and trusts under their voting
discretion. Thus, certain directors of the Company, their direct family members,
or accounts, companies and trusts under their discretion control 49% of the
Common Stock outstanding as of the Record Date and they have committed to vote
all of their combined Common Stock in favor of the Merger Agreement. See
"DESCRIPTION OF PROPOSED MERGER--SHAREHOLDERS' AGREEMENT."
 
    Proxies for use at the Special Meeting accompany this Proxy Statement.
Properly executed and returned proxies, unless revoked, will be voted as
directed by the shareholder, or, in the absence of such direction, by the
persons named therein FOR the approval and adoption of the Merger Agreement and
the Merger in accordance with the recommendation of the Board. As to any other
business which may properly come before the Special Meeting, the proxy holders
will vote in accordance with their best judgment. A proxy may be revoked at any
time before it is voted by delivery of written notice of revocation to the
Secretary of the Company, or by delivery of a subsequently dated proxy, or by
attendance at the Special Meeting and voting in person. Attendance at the
Special Meeting without also voting will not in and of itself constitute the
revocation of a proxy.
 
    The Company will bear the costs of printing this Proxy Statement and
soliciting proxies from shareholders. It is expected that proxies will be
solicited by the Company principally through the use of the mail. In addition,
if it should appear desirable to do so, directors, officers and employees of the
Company may, without additional compensation, communicate with shareholders, and
with banks, brokerage houses, nominees and others by telephone, telegraph,
facsimile or in person, to request that proxies be furnished.

    SHAREHOLDERS SHOULD NOT SEND ANY CERTIFICATES REPRESENTING COMMON STOCK WITH
THE ENCLOSED PROXY CARD. A LETTER OF TRANSMITTAL WILL BE MAILED BY THE PAYING
AGENT FOLLOWING THE EFFECTIVE DATE TO EACH PERSON WHO WAS A HOLDER OF RECORD OF
COMMON STOCK ON THE EFFECTIVE DATE. SHAREHOLDERS SHOULD SEND CERTIFICATES
REPRESENTING COMMON STOCK TO THE PAYING AGENT ONLY AFTER THEY RECEIVE, AND ONLY
IN ACCORDANCE WITH, THE INSTRUCTIONS CONTAINED IN THE LETTER OF TRANSMITTAL.
 
                       DESCRIPTION OF THE PROPOSED MERGER
 
    The following information with respect to the proposed Merger and the Merger
Agreement does not purport to be complete and is qualified in its entirety by
reference to the Merger Agreement included herein as Appendix I.
 
BACKGROUND OF AND REASONS FOR THE MERGER
 
    HISTORY OF NEGOTIATIONS BETWEEN THE COMPANY AND GENERAL ELECTRIC
 
    During the past several years the medical equipment service industry has
been characterized by increasing consolidation, with participants seeking the
capability of providing a full range of products and services to their
customers. In addition, consolidation in the medical care industry has caused an
increase in the capital required by companies to compete in the industry, while
enhancing the outlook for larger companies which provide greater economies of
scale.
 
    During this period, management of the Company reviewed the Company's
strategic alternatives and took various steps in an effort to maintain its
competitiveness. In addition, the Company has strived to improve its
profitability by (i) streamlining its operations, including terminating
unprofitable or less profitable service contracts; (ii) installing new
information systems, which have reduced working capital requirements and
enhanced responsiveness to customers; and (iii) broadening its capabilities in
the medical equipment services industry through new alliances and marketing
initiatives.
 
    Despite these efforts, the Company continued to have unprofitable operating
results and liquidity concerns, and continued to lose market share and its
competitive advantages in the consolidating marketplace. As a result, in late
1996, the Company's management and the Board determined that it was in the best
interests of the Company to explore the possibilities of seeking a buyer for
substantially all of the assets or stock of the Company. Pursuant to this
determination, the Company engaged Warburg Dillon Read LLC ("WDR") on October
21, 1996 to make inquiries on the Company's behalf to interested buyers in the
medical equipment services industry.
 
    During the remainder of 1996 and the first half of 1997, the Company and WDR
took affirmative steps to locate such a buyer. In late 1996 and the first half
of 1997, the Company and WDR identified and entered into confidentiality
agreements with approximately 10 potential buyers, including General Electric,
and requested that each potential buyer provide a verbal indication of interest
in acquiring the Company. Upon the receipt of such verbal indications, the
Company provided each potential buyer with access to due diligence materials
regarding the Company.
 
    As a result of this process, in early 1997, two of the parties conducting
due diligence submitted further indications of interest to the Company. One of
the indications involved the potential purchase of only a portion of the assets
of the Company for cash. The other involved the potential purchase of
substantially all of the assets of the Company. The Board met on February 3,
1997 and February 6, 1997 to discuss each of these indications of interest. The
Board determined that it was not in the best interests of the Company to
entertain negotiations regarding the sale of only a portion of the assets of the
Company. Therefore, the Board decided not to move forward with respect to the
first party. With respect to the second indication, the Board determined that
the amount of consideration being offered was too low, particularly in light of
 
                                       13
<PAGE>
the specified conditions required to close the transaction. Therefore, the Board
also decided not to move forward with respect to the second party.
 
    During March through July of 1997, two additional parties who had conducted
diligence with respect to the Company indicated an interest in acquiring the
Company. However, the terms, contingencies and valuations offered by these
parties were not within the range that the Board and the Company's management
thought appropriate to continue negotiations.
 
    General Electric did not express any further interest until September 17,
1997 when a representative of General Electric spoke with Mr. Puls of the
Company expressing General Electric's interest in entertaining discussions about
a potential acquisition of the Company. As a result of this conversation, Mr.
Puls and Mr. Hoefert of the Company met with representatives of General Electric
on October 17, 1997 in Dallas, Texas to acquaint General Electric with a history
of the Company and to assess General Electric's interest in acquiring the
Company.
 
    On October 31, 1997, a representative of General Electric verbally contacted
WDR to express General Electric's interest in pursuing an acquisition of all of
the equity interests of the Company for $16 to $20 million in cash. However, due
to the limited knowledge of General Electric in the operations of the Company,
General Electric requested that it be allowed to engage in preliminary due
diligence prior to the issuance of a letter of intent or other proposal.
Pursuant to the request, the Company provided certain due diligence materials to
General Electric and on November 27, 1997 General Electric submitted an
additional preliminary due diligence request list to WDR.
 
    On December 1, 1997, Mr. Puls and Mr. Hoefert met with representatives of
General Electric in Chicago, Illinois to review the General Electric due
diligence request and oral indication of interest. Following this meeting, on
December 9 and 10, 1997, General Electric representatives conducted preliminary
due diligence and Mr. Puls and Mr. Hoefert met with representatives of General
Electric to discuss the General Electric due diligence and to provide additional
data to General Electric. On December 12, 1997, the Board met to discuss the
progress of the General Electric due diligence and General Electric's oral
indication of interest.
 
    At an industry conference in early December, a representative from a party
("Party A") who had signed a confidentiality letter with the Company earlier,
met with Mr. Puls informally to discuss the possibility of acquiring all of the
equity or all, or substantially all, of the assets of the Company. Following
this conversation, Party A submitted a letter on December 9, 1997 (the "Party A
Letter") indicating an interest in purchasing all of the equity interests in the
Company. However, after informal discussions with the Board, WDR notified Party
A that the Company was not interested in pursuing negotiations with Party A
since the price range offered was not within a range deemed appropriate by the
Board. During the industry conference, Mr. Puls also met informally with a
representative of a party ("Party B") who had not previously signed a
confidentiality agreement with the Company regarding a potential acquisition of
all of the assets of the Company.
 
    Following its preliminary due diligence, General Electric submitted two
non-binding letters to the Company on December 19, 1997 (the "General Electric
Letter") setting forth the terms of a possible merger of a subsidiary of General
Electric with and into the Company for a price of between $15 million and $16.48
million, based on certain assumptions and subject to various contingencies. The
General Electric Letter also referred to additional actions to be taken after
signing, including a provision for both companies to make filings under the
Hart-Scott-Rodino Antitrust Improvement Act of 1976 ("HSR Act"), for which
General Electric agreed to pay all filing fees. As a part of the letter, General
Electric required a binding "exclusive dealing" agreement with the Company for a
period commencing on the date of the General Electric Letter and ending on the
earlier of (i) February 15, 1998 or (ii) thirty-one (31) days after the HSR Act
filing if the HSR Act waiting period had not already expired.
 
                                       14
<PAGE>
    The Board met on December 22, 1997 to review the General Electric Letter and
General Electric's requirement of an "exclusivity" agreement. In deciding
whether to agree to the terms of the General Electric Letter, the Board
determined that the consideration offered by General Electric was within an
acceptable range of the Board's own assessment of the value of the Company. The
Board also found it significant that General Electric had expressed a strong
commitment to proceeding with the Company (as shown by its willingness to
proceed with and pay for the HSR Act filing) and that it had the ability to
close a potential transaction without contingent financing. For these reasons,
the Board decided that it was in the best interests of the Company to pursue the
possible acquisition by General Electric, and therefore decided to grant General
Electric exclusivity in accordance with the General Electric Letter.
 
    Based on the General Electric Letter, General Electric made filings under
the HSR Act on December 24, 1997 and the Company made filings under the HSR Act
on December 30, 1997. Shortly thereafter, General Electric continued its due
diligence investigation of the Company, and General Electric and the Company
began preliminary negotiations of a draft merger agreement and related
documents, including a shareholder voting agreement. On January 16, 1998, the
Company's Board met to discuss the status of the General Electric negotiations
and the draft merger agreement, and the Board's material negotiation points and
strategies, based on comments received from General Electric with respect to the
draft merger agreement.
 
    On January 27, 1998, the DOJ notified the Company that the DOJ needed
additional information with respect to the proposed transaction, and on the
following day, General Electric notified the Company that the DOJ had requested
additional information from General Electric on the proposed transaction. The
Board met on January 28, 1998 to discuss the requests regarding the HSR Act
filings. On January 29, 1998, the DOJ made a formal "second request" of the
Company and General Electric regarding the HSR Act filings, seeking extensive
documents and information in connection with its analysis of a possible
transaction. As a result of the "second request," the preliminary negotiations
between General Electric and the Company of the draft merger agreement ceased at
that time; however, the parties did agree to continue to work with the DOJ with
respect to the HSR Filings, and shortly thereafter, General Electric and the
Company produced certain information requested by the DOJ and met with the DOJ.
On January 30, 1998, the "exclusive dealing" provisions of the General Electric
Letter expired.
 
    On January 30, 1998, two additional parties ("Party C" and "Party D"),
neither of whom had signed confidentiality letters with the Company earlier nor
had been involved in discussions with WDR regarding the Company, jointly
submitted an unsolicited non-binding letter (the "Party C/D Letter") indicating
an interest in acquiring all of the equity interests of the Company for cash in
an amount equal to between $17.6 million and $20.1 million. The Party C/D Letter
required Party D to invest capital in Party C, allowing Party C to acquire the
equity of the Company. The Party C/D Letter was subject to due diligence and
automatically terminated unless accepted by February 2, 1998. On January 31,
1998, the Board met to discuss the progress in responding to the DOJ's request
for additional data and information regarding the proposed General Electric
transaction and reviewed the Party C/D Letter. In light of the DOJ request, the
Board decided to pursue discussions with Party C and Party D and instructed WDR
to notify Party C and Party D with respect to such decision.
 
    On February 2, 1998, WDR contacted Party C and Party D and negotiated and
executed a confidentiality agreement on behalf of the Company. On February 3,
1998, representatives of Party C and Party D met with Mr. Puls and Mr. Hoefert
in Dallas, Texas to discuss Party D's strategy for making an investment in Party
C and the concurrent acquisition of the Company by Party C. At this meeting, Mr.
Puls and Mr. Hoefert reviewed certain of the Company's publicly available
information with Party C and Party D and discussed certain aspects of the
Company's operations. On February 4, 1998, representatives of Party C and D
continued their due diligence review of the Company.
 
    Throughout early February 1998, General Electric and the Company continued
document production to and discussions with the DOJ. On February 11, 1998, after
a conversation with WDR one day earlier,
 
                                       15
<PAGE>
Party B submitted an unsolicited non-binding letter (the "Party B Letter")
indicating an interest in acquiring all or substantially all of the assets of
the Company for cash in an amount equal to $20 million. The Party B Letter was
contingent on extensive due diligence. On February 13, 1998, WDR negotiated and
executed a confidentiality agreement on behalf of the Company with Party B.
Meanwhile, on February 13, 1998, the Company again met with the DOJ to discuss
the proposed transaction with General Electric. On February 16, 1998, the Board
met to discuss the progress of the DOJ discussions, the progress of discussions
with Party C and Party D and the Party B Letter.
 
    On February 17, 1998, Party C and Party D submitted a revised non-binding
letter (the "Revised Party C/D Letter") indicating an interest in acquiring all
of the equity interests of the Company for cash in an amount equal to $20
million. The Revised Party C/D Letter was contingent upon extensive additional
due diligence of the Company and a binding four week "exclusive dealing" period.
 
    On February 19, 1998, Mr. Puls and Mr. Hoefert met with Party B
representatives in Dallas, Texas to review certain of the Company's publicly
available information and to provide additional information with respect to the
Company's operations. Party B representatives continued Party B's due diligence
review of the Company on February 20, 1998.
 
    On February 23, 1998, the Board met to discuss the Revised Party C/D Letter,
the progress of the Party B negotiations and the progress in responding to the
DOJ's request for additional data and information regarding the proposed General
Electric transaction. The Board expressed its desire to pursue discussions with
Party C and Party D, but was concerned about extending exclusivity to Party C
and Party D. Throughout the discussions with Party C and Party D, the management
of the Company and the Board had been concerned with the level of commitment
exhibited by Party D (the financing entity for Party C) to a possible
transaction, and its effect upon the ability of Party C to close a transaction
with the Company. In addition, the Company's management and the Board believed
that the extensive nature of the additional diligence requested in the Revised
Party C/D Letter placed such a contingency on the likelihood of a transaction as
to make exclusivity unwarranted in this case. Finally, based on these factors,
as well as continued discussions with the DOJ and General Electric, and the
preliminary interest of Party B, the Board decided that it was not in the best
interests of the Company to grant exclusivity to any party at that time. The
Board instructed WDR at the February 23, 1998 meeting to notify Party C and
Party D of its desire to pursue discussions with Party C and Party D, but only
if such parties agreed to waive the "exclusive dealing" provision. Party C and
Party D declined to waive the "exclusive dealing" provision of the Revised Party
C/D Letter and on February 25, 1998, Party C and Party D confirmed in writing
the termination of the Revised Party C/D Letter.
 
    On or about March 3, 1998, the DOJ notified General Electric and the Company
of its intention to contact certain third parties (customers, competitors and
original equipment manufacturers) in connection with its review and analysis of
the proposed General Electric transaction.
 
    On March 12, 1998, Party B informed WDR that it was not interested in
acquiring all of the equity or assets of the Company. Instead, Party B was
interested in pursuing discussions to purchase only certain assets and business
units of the Company for cash. Throughout its attempt to find a potential buyer,
the Company had determined and had been advised by WDR that it was not in the
best interests of the Company to divest only selected assets unless a purchaser
for the remaining assets could be found that would be willing to negotiate and
close concurrently with any divestiture of selected assets of the Company. Since
no such other purchaser was known to the Board or believed by the Board to be
likely to surface, WDR responded to Party B that the Company was not presently
interested in divesting such selected assets. Party B then indicated that it was
no longer interested in pursuing a transaction with the Company. Nevertheless,
Mr. Puls contacted a Party B representative about the possible divestiture of
one specific business unit. Party B notified the Company on April 21, 1998 that
it was not interested in acquiring the specific business unit.

    On March 20, 1998, Party C and Party D contacted WDR to express their desire
to resume discussions with the Company. The Board met on March 23, 1998 to
discuss the conditions necessary to continue discussions with Party C and Party
D. The Board again reviewed the "exclusive dealing" request of Party C and Party
D and again decided it was not in the best interests of the Company to grant
exclusivity to any party at that time. The Board also again discussed its
concerns regarding the contingent nature of the financing from Party D. WDR
notified Party C and Party D that these issues would need to be addressed by
Party C and Party D before negotiations could continue. Based on this
conversation, on March 25, 1998, Party C and Party D provided to the Company a
commitment for financing from Party D, Party D's Board of Directors approval of
the investment of Party D in Party C, and a waiver of the exclusivity clause in
the Revised Party C/D Letter. Based on this, discussions were resumed and on
March 26, 1998, Party C and Party D and their representatives met with Mr. Puls
and Mr. Hoefert in Dallas, Texas to continue their due diligence of the Company.
Party C and Party D continued such due diligence through April 7, 1998. On April
8, 1998, representatives of Party C and Party D contacted WDR to discuss the
decision by Party D to withdraw its financing commitment to Party C and to
withdraw from the acquisition discussions. During this meeting, Party C stated
its interest in continuing discussions once it had secured additional financing
sources; however, Party C indicated that the consideration offered in the
Revised Party C/D Letter would need to be revised due to the withdrawal of Party
D and to a perceived deterioration in the financial condition of the Company.
Meanwhile, on April 3, 1998, the DOJ informed General Electric and the Company
that it could take several more weeks to complete its contact with third parties
regarding the transaction.
 
    After Party D withdrew its proposal from consideration, the Company became
concerned about its limited options. Party B had withdrawn its proposal, Party C
had no source of financing, and the Company had encountered operating losses
throughout the period that the Company was seeking an acquiror, thereby
increasing its liquidity concerns. Additionally, the Company had been seeking a
potential acquiror for more than 15 months and no additional potential buyers
had surfaced. Finally, because of the length of the proposed DOJ review, the
management of the Company was concerned that rumors concerning a possible
business combination would begin to disrupt the ongoing operations of the
Company. Therefore, in order to proceed toward entering into a definitive
agreement with General Electric, on April 10, 1998, Mr. Puls and Mr. Rauch,
Chairman of the Board, met in Milwaukee, Wisconsin with General Electric
representatives. During the meeting the parties proposed to eliminate any aspect
of the contingent consideration and proposed a price of $16,000,000 for the
Company plus payment of in-the-money Company stock options. After such meeting,
General Electric and the Company resumed the negotiations regarding the draft
merger agreement.
 
    On or about April 15, 1998, the DOJ suggested the possibility of continuing
and expanding its investigation with respect to General Electric and the
Company. However, shortly thereafter General Electric met with the DOJ and
discussions regarding possible resolution of the HSR Act issues resumed. During
the following two weeks, General Electric and the Company continued discussions
with the DOJ regarding the possible resolution of the HSR Act issues.
Additionally, General Electric and the Company continued negotiating an
agreement and plan of merger and General Electric engaged in further due
diligence investigations. During the last week of April 1998 and the first week
of May 1998, General Electric and the Company began negotiations of possible
schedules, exhibits, opinions and other ancillary documents in connection with
the negotiations of the draft merger agreement. During this period, there were
no further meaningful conversations with Party A, Party B, Party C or Party D;
however, WDR received a draft of a merger agreement from Party C on April 22,
1998.
 
    On May 5, 1998, the Board met with the Company's legal counsel and financial
advisors to review and discuss a written description of the terms of the draft
merger agreement being negotiated with General Electric, to review the status of
negotiations and to discuss various other matters related to the proposed
transaction. At this meeting, WDR expressed its oral opinion that the
consideration to be received in the proposed Merger is fair, from a financial
point of view, to the shareholders of the Company, and discussed
 
                                       17
<PAGE>
the analyses, methodologies and conclusions underlying such determination. The
Board felt that the verbal presentation was complete and sufficient and,
therefore, that review of a written copy of the financial analysis was not
required.
 
    Although the terms of the Merger were acceptable to the Board, because of
the disruption in operations which might be caused by announcing the Merger, the
Company informed General Electric that it was unwilling to execute and deliver a
definitive agreement unless General Electric would be willing to (i) compensate
the Company if the DOJ did not terminate the HSR waiting period and (ii) make a
substantial investment in the Company upon execution of such an agreement. On
May 7, 1998, the Board met to discuss the above-described options and to set
certain parameters for a possible resolution of these issues with General
Electric. After additional negotiations between the parties, General Electric
agreed to (i) a payment of $1,200,000 to the Company upon the occurrence of
certain events related to the DOJ and (ii) an equity investment of $2,800,000 by
General Electric in the Company by purchasing 700,000 shares of a new class of
the Company's preferred stock. See "REGULATORY APPROVAL" and "PREFERRED STOCK."
 
    On May 11, 1998, the Board met again with the Company's legal counsel and
financial advisors to review and discuss a written description of the proposed
changes to the terms of the proposed merger agreement based on negotiations
since May 5, 1998, and a representative of WDR confirmed its May 5, 1998 oral
opinion that the consideration to be received in the proposed merger was fair,
from a financial point of view, to the shareholders of Company. After
discussion, the Board unanimously approved the form of the proposed merger
agreement and authorized the appropriate officers to enter into the definitive
agreement so long as General Electric agreed to the $1,200,000 payment and the
purchase of the preferred stock described above. On May 11, 1998, WDR issued its
written opinion that the consideration to be received in the proposed merger was
fair, from a financial point of view, to the shareholders of Company.
 
    From May 11, 1998 through May 19, 1998, the parties continued to negotiate
and finalize the proposed merger agreement and the related ancillary documents.
On May 15, 1998, the Board again met with the Company's legal counsel and
financial advisors to review additional changes to the proposed merger agreement
and to discuss various details regarding the proposed preferred stock issuance.
The Board again unanimously approved the form of the proposed merger agreement
and authorized the appropriate officers to enter into the definitive agreement.
At this meeting, WDR orally affirmed its written opinion of May 11, 1998 that
the consideration to be received in the proposed merger was fair, from a
financial point of view, to the shareholders of Company. Over the weekend of May
16-17, 1998 and on May 18-19, 1998, the parties finalized the language of the
Merger Agreement and the ancillary documents related thereto. After the close of
business on May 19, 1998, the parties executed and delivered the Merger
Agreement and all ancillary documents thereto.
 
    REASONS FOR THE MERGER
 
    At the time the Merger Agreement was negotiated and executed, General
Electric was the only party that had made a qualified offer to purchase either
all of the stock or all of the assets of the Company. The terms of the Merger
were determined through negotiations between the Company and General Electric
following extensive discussions, financial analyses and due diligence. In
reaching its determination on May 15, 1998 to approve and adopt the Merger
Agreement and recommend approval of the Merger Agreement and the Merger to the
Company's shareholders, the Board consulted with the Company's management, as
well as its legal counsel and financial advisors, and considered a number of
factors before determining that the Merger represented the best available
alternative to enhance shareholder value. These factors included: (i) the
presentation by WDR with respect to WDR's determination as to the fairness, from
a financial point of view, of the Per Share Merger Consideration to the
shareholders of the Company, and the analyses, methodologies and conclusions
underlying such determination (see "FAIRNESS OPINION"); (ii) the premium in
existence at the time of approximately $0.97 to $1.25 per share (approximately
33% to approximately 42%), which represents the difference between the Per Share
Merger
 
                                       18
<PAGE>
Consideration, as adjusted by the pro rata share of the Escrow Payment, if any,
and the trading price of the Common Stock at such time; (iii) the lack of any
available strategic alternatives, including the probability of obtaining a
superior offer and the timing thereof; (iv) the historical and recent sales and
earnings of the Company; (v) the Company's future prospects and potential
opportunities; (vi) the prices and premiums paid in recent acquisitions of
companies deemed to be similar in certain respects to the Company; (vii) the
advantages to the Company's shareholders of an all cash offer for their shares;
(viii) the likelihood that the Merger could be consummated, noting the timing of
and conditions to the Merger; and (ix) the terms and conditions of the Merger
Agreement, including, without limitation, the right of the Company to respond to
unsolicited third party superior proposals, subject to payment of $550,000 in
the event of entering into a transaction with such a third party; (x) the
payment by General Electric of $1,200,000 to the Company should early
termination or expiration of the waiting period under the HSR Act not be granted
prior to the later of (A) June 22, 1998 or (B) the date of the meeting of the
shareholders of the Company at which the Merger is approved; and (xi) infusion
of cash to the Company resulting from the $2,800,000 purchase of the Preferred
Shares (as hereinafter defined) by General Electric following execution of the
Merger Agreement.
 
    The Board then unanimously concluded that the Merger with General Electric
represented the best available alternative to enhance shareholder value. The
Board did not find it practicable to, and did not attempt to, assign relative
weights to the specific factors considered.
 
FAIRNESS OPINION
 
    The Company retained WDR to render a fairness opinion in connection with the
Merger. WDR has delivered its written opinion, dated May 11, 1998, confirming
its oral opinion of May 5, 1998 to the Board to the effect that, and based upon
and subject to the assumptions, limitations and qualifications set forth
therein, as of the date thereof, the consideration to be received in the Merger
is fair, from a financial point of view, to the shareholders of Common Stock.
 
    The full text of WDR's fairness opinion, dated May 11, 1998, which sets
forth a description of the assumptions made, general procedures followed,
matters considered and limitations on the review undertaken, is attached as
Appendix II to this Proxy Statement. WDR's opinion does not address the
Company's underlying business decision to effect the Merger or constitute a
recommendation to any shareholder of the Company as to how such shareholder
should vote with respect to the Merger. The summary of WDR's opinion set forth
below is qualified in its entirety by reference to the full text of such opinion
attached as Appendix II. SHAREHOLDERS ARE URGED TO READ THE OPINION CAREFULLY IN
ITS ENTIRETY, ESPECIALLY WITH REGARD TO THE ASSUMPTIONS MADE AND MATTERS
CONSIDERED BY WDR.
 
    In connection with rendering the fairness opinion, WDR reviewed, analyzed
and relied upon material relating to the financial and operating condition of
the Company, including, among other things, the following: (i) the draft Merger
Agreement; (ii) certain publicly available information concerning the Company,
including the Annual Reports on Form 10-K of the Company for each of the years
in the three year period ended April 30, 1997 and the Quarterly Reports on Form
10-Q of the Company for the quarters ended July 31, 1997, October 31, 1997 and
January 31, 1998; (iii) certain other internal information, primarily financial
in nature, concerning the business and operations of the Company furnished to
WDR by the Company for purposes of its analysis; (iv) certain publicly available
information concerning the trading of, and the trading market for, the Common
Stock; (v) certain publicly available information with respect to certain other
companies that WDR believed to be comparable to the Company and the trading
markets for certain of such other companies' securities; (vi) discussions
conducted with members of the senior management of the Company; (vii) certain
publicly available information concerning the nature and terms of certain other
transactions that WDR considered relevant to its inquiry; and (viii) such other
financial studies, analyses and investigations, and such other information as
WDR deemed necessary and appropriate, but none of which was individually
material. WDR's opinion was necessarily
 
                                       19
<PAGE>
based on economic, monetary, market and other conditions as in effect on, and
the information made available to WDR as of, the date thereof.
 
    In connection with its review, WDR did not, with the Company's consent,
assume any responsibility for independent verification of any of the information
reviewed by it for the purposes of its opinion, and with the Company's consent
relied upon its being complete and accurate in all material respects. In
addition, with the Company's consent WDR did not make any independent evaluation
or appraisal of any of the assets or liabilities (contingent or otherwise) of
the Company, nor was WDR furnished with any such evaluation or appraisal.
 
    For the purposes of the opinion, with the consent of the Company, WDR
assumed that the representations and warranties of each party contained in the
Merger Agreement were true and accurate, that each party thereto would perform
all of the covenants and agreements required to be performed by it under the
Merger Agreement and that all conditions to the consummation of the Merger would
be satisfied without waiver thereof. The Company did not place any limitations
upon WDR regarding the procedures to be followed or the factors to be considered
in rendering its opinion.
 
    In arriving at its opinion, WDR did not assign any particular weight to the
factors considered by it, but rather made qualitative judgments based upon its
expertise in providing such opinions and on then existing economic, monetary,
market and other conditions as to the significance and relevance of each
analysis and factor. Accordingly, WDR believes that its analyses must be
considered as a whole and that selecting portions of its analysis and the
factors considered, without considering all analyses and factors, could create a
misleading or incomplete view of the processes underlying its opinion. In its
analyses, WDR made numerous assumptions with respect to industry performance,
general business and economic conditions and other matters, many of which are
beyond the control of the Company or WDR. Any assumed estimates contained in
WDR's analyses are not necessarily indicative of actual values or predicative of
future results or values, which may be significantly more or less favorable than
as set forth therein. Such estimates relating to the value of a business or
securities do not purport to be appraisals or necessarily reflect the prices at
which companies or securities may actually be sold.
 
    In connection with a presentation to the Board on May 5, 1998, as confirmed
in the written opinion of May 11, 1998, WDR advised the Board that, in
evaluating the consideration to be received in the Merger by the holders of the
Common Stock, WDR had performed a variety of financial analyses with respect to
the Company. In connection with rendering its opinion, WDR employed a variety of
valuation methods. The material methods used are summarized below.
 
    PREMIUM ANALYSIS
 
    WDR calculated the premium to holders of the Common Stock of the Per Share
Merger Consideration to the per share closing price of the Common Stock on May
1, 1998, and to the 52 week high and low closing stock price for the Common
Stock during the latest twelve months ("LTM"). In calculating such amounts, WDR
calculated the Per Share Merger Consideration to be received based upon the
total current number of shares outstanding as of May 5, 1998 and assumed that
the Escrow Payment was not disbursed to the shareholders of the Company. WDR
calculated premiums to holders of the Company Common Stock equal to
approximately 33% of the closing stock price for the Common Stock of $3.00 on
May 1, 1998; 165% of the 52 week low closing stock price of $1.50 for the Common
Stock; and 10% of the 52 week high closing price of $3.625 for the Common Stock.
 
    WDR also calculated multiples of the Company's "Implied Firm Value" (defined
as the aggregate offer price for the Common Stock--$16,000,000 (the Merger
Consideration)--plus book values of total debt, less cash and cash equivalents)
to its LTM revenues and also calculated the Per Share Merger Consideration as a
multiple of its latest fiscal quarter tangible book value. The results of the
calculations were as follows: Implied Firm Value to LTM sales of 0.4x and Per
Share Merger Consideration to tangible book value of 2.6x.
 
                                       20
<PAGE>
    ANALYSIS OF SELECTED PUBLICLY-TRADED COMPARABLE COMPANY
 
    WDR reviewed certain publicly available financial, operating and stock
market information as of May 1, 1998 for the Company and Cohr, Inc., which in
WDR's judgment was generally comparable to the Company for purposes of this
analysis.
 
    WDR calculated, among other things, multiples of market price to latest
fiscal quarter tangible book value per share, and multiples of Firm Value
(Implied Firm Value in the case of the Company) to LTM revenues. "Firm Value" is
defined as the value of the equity of the company plus book values of total
debt, less cash and cash equivalents. An analysis of the multiples of market
price to latest fiscal quarter tangible book value per share yielded 2.6x for
the Company and 0.9x for Cohr, Inc. An analysis of the multiples of Firm Value
to LTM revenues yielded 0.4x for the Company and 0.3x for Cohr, Inc.
 
    ANALYSIS OF RECENT ACQUISITION ACTIVITY
 
    WDR also reviewed three transactions involving the acquisition of all or
part of certain medical maintenance related companies, which in WDR's judgment
were generally comparable to the Merger for the purposes of this analysis. WDR
calculated the multiples of Firm Value to LTM revenues, as well as the multiple
of the offer price in each such transaction to the respective book value of such
companies.
 
    The acquisitions reviewed by WDR, in reverse chronological order of
announcement date included: (i) the acquisition by Steris Corp. of Amsco
International, (ii) the acquisition by MMI Medical, Inc. (the Company) of MEDIQ
Equipment and Maintenance Services, Inc. and (iii) the acquisition by Elbit Ltd.
of Diasonics Ultrasound.
 
    These calculations yielded a range of Firm Value to LTM revenues of 0.35x to
1.06x with a median of 0.65x, and a range of price to book value of 0.9x to 2.1x
with a median of 1.5x. WDR then compared the results of these calculations to
multiples calculated using the Implied Firm Value and the Merger Consideration:
0.4x Implied Firm Value to the Company's LTM revenues and 2.6x Merger
Consideration to book value of the Company.
 
    No company, transaction or business used in the analysis described under
"ANALYSIS OF RECENT ACQUISITION ACTIVITY" and "ANALYSIS OF SELECTED
PUBLICLY-TRADED COMPANY" above is identical to the Company or the Merger.
Accordingly, an analysis of the results thereof necessarily involves complex
considerations and judgments concerning differences in financial operating
characteristics and other factors which could effect the transaction or the
public trading or other values of the company or companies to which they are
being compared. Mathematical analysis (such as determining the average or
median) is not in itself a meaningful method of using comparable acquisition or
comparable company data.
 
    WDR has advised the Board that, in connection with rendering its written
opinion dated May 11, 1998, WDR considered certain financial information and
market data in performing updates to the financial analyses described above. WDR
stated that the updated financial analyses confirmed its opinion as described
above.
 
    WDR is an internationally recognized investment banking firm which, as part
of its investment banking business, regularly engages in the evaluation of
businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, competitive bids, secondary distributions of listed
and unlisted securities, private placements and valuations for estate, corporate
and other purposes. The Board selected WDR on the basis of its experience and
independence.
 
    In the ordinary course of business, WDR and its affiliates may actively
trade or hold the equity securities of the Company or the other merger
participants for their own account or the accounts of their customers and,
accordingly, may at any time hold a short or long position in such securities.
 
    Pursuant to the engagement letter with WDR, the Company has agreed to pay
WDR a fee of $500,000 upon consummation of a disposition of all of the Company's
stock or substantially all of the assets of the
 
                                       21
<PAGE>
Company whether by way of merger, transfer of assets or otherwise, for cash or
securities, in one or a series of transactions with any party. The Company has
also agreed to reimburse WDR for certain expenses incurred in connection with
its engagement and to indemnify WDR and certain related persons against certain
liabilities and expenses relating to or arising out of its engagement, including
certain liabilities under the federal securities laws.
 
RECOMMENDATION
 
    The Board believes that the Merger is fair to, and in the best interests of,
the Company and its shareholders. Accordingly, the Board has unanimously
approved the Merger Agreement and the Merger and unanimously recommends that the
shareholders vote "FOR" approval and adoption of the Merger Agreement and the
Merger. Under California law, the Merger cannot be consummated without the
affirmative vote of the holders of a majority of the outstanding shares of
Common Stock in favor of the Merger Agreement and other transactions
contemplated thereby, including the Merger.
 
SHAREHOLDERS' AGREEMENT
 
    Pursuant to the Shareholders' Agreement and subject to the terms and
conditions therein, the Committed Shareholders have agreed to vote all of their
shares of Common Stock in favor of approval of the Merger Agreement and the
Merger. As of the Record Date, the Committed Shareholders held 1,589,279 shares
of Common Stock, constituting nearly 53% of the shares of Common Stock
outstanding on such date, an amount sufficient to approve the Merger Agreement
and the Merger at the Special Meeting. Pursuant to the Shareholders' Agreement,
the Committed Shareholders agreed, until the termination of the Shareholders'
Agreement, to (i) attend the Special Meeting and vote their shares of Common
Stock in favor of the Merger; (ii) vote against any Business Combination
Proposal; (iii) not divest of any such shares of Common Stock; and (iv) not to
take any action as a shareholder to solicit a third party proposal with respect
to the purchase or combination of the assets or stock of the Company. The
Shareholders' Agreement terminates upon the earlier to occur of September 30,
1998 or the termination of the Merger Agreement, provided that, if the Merger
Agreement is terminated as a result of the shareholders of the Company voting
against the Merger, the provisions of the Shareholders' Agreement listed above
shall survive for 180 days after such termination.
 
    Ninety-three percent (93%) of the approximately 53% of shares held by the
Committed Shareholders are held individually by directors of the Company, their
direct family members, or in accounts, companies and trusts under their voting
discretion. Thus, certain directors of the Company, their direct family members,
or accounts, companies and trusts under their discretion control 49% of the
outstanding Common Stock of the Company on the Record Date and they have
committed to vote all of their combined Common Stock in favor of the Merger
Agreement.

THE MERGER
 
    Subject to the conditions and the termination provisions contained in the
Merger Agreement, the proposed Merger will become effective on the Effective
Date, the date on which the Agreement of Merger of Sub into the Company attached
as Exhibit A.1 to the Merger Agreement, along with any other required documents,
is duly filed with and accepted by the Secretary of State of California. It is
currently anticipated that, if the Merger Agreement is approved and adopted by
the shareholders of the Company at the Special Meeting, and all other conditions
to the Merger have been fulfilled or waived, the Effective Date will occur on
the date that the Special Meeting has been scheduled, or a date as soon as
practicable thereafter. Upon consummation of the Merger, Sub will merge with and
into the Company, the separate existence of Sub as a corporation will cease, and
the Company will remain as the Surviving Corporation and will be an indirect
subsidiary of General Electric.
 
MERGER CONSIDERATION
 
    PER SHARE MERGER CONSIDERATION
 
    If the Merger is consummated, the Merger Agreement provides that each
outstanding share of Common Stock (other than (i) shares held by General
Electric or Sub, (ii) shares held by any corporation, partnership, joint
venture, or other entity in which the Company (A) owns directly or indirectly,
50% or more of the outstanding voting securities or equity interests (other than
the shares held by the InnoServ Technologies, Inc. Employee Stock Purchase Plan)
or (B) is a general partner (a "Company Subsidiary"), (iii) shares held by any
corporation, partnership, joint venture or other entity in which General
Electric (A) owns, directly or indirectly, 50% or more of the outstanding voting
securities or equity interests or (B) is a general partner (a "General Electric
Subsidiary"), and (iv) Dissenting Shares in respect of which appraisal rights
are properly exercised and perfected) will, on the Effective Date, be converted
into (i) the right to receive an amount equal to (A) the sum of $16,000,000 less
the MEDIQ Payment and less the Escrow Payment, divided by (B) the number of
shares of Common Stock outstanding as of the Effective Date, and (ii) the
contingent right to receive additional consideration pursuant to the Escrow
Agreement. As of the Record Date, 3,009,395 shares of Common Stock were
outstanding. If the number of shares of outstanding Common Stock remains the
same on the Effective Date, the Per Share Merger Consideration will be
approximately $3.97.
 
    MEDIQ PAYMENT
 
    Pursuant to the MEDIQ Agreement, by and among the Company and MEDIQ (a copy
of which is attached hereto as Appendix III), in 1997 the Company repurchased
2,026,438 shares of the Company's Common Stock ("the MEDIQ Shares") from MEDIQ
in exchange for an agreement that the Company would not enter into or consummate
a change of control (as defined in the MEDIQ Agreement) unless the other party
or parties thereto agree, as a condition precedent to such transaction, to pay
to MEDIQ the amount that would have been received by MEDIQ in connection with
the change of control transaction if all of the MEDIQ Shares were outstanding
and held by MEDIQ at the effective time of such change of control transaction.
The MEDIQ Agreement further provides that, after April 1, 1998 and through
September 30, 1998, the Company shall not enter into or consummate a change of
control unless the other party or parties thereto agree as a condition precedent
to such transaction, to pay to MEDIQ 50% of the amount that would have been
received by MEDIQ in connection with the change of control transaction if all of
the MEDIQ Shares were outstanding and held by MEDIQ at the effective time of
such change of control transaction. A change of control under the MEDIQ
Agreement includes a transaction whereby the holders of a majority of the
outstanding shares of Common Stock receive cash in exchange for such Common
Stock pursuant to a merger.
 
    MEDIQ and the Company are currently in dispute as to the amount that would
be owed to MEDIQ under the terms of the MEDIQ Agreement upon consummation of the
Merger. If the Company and
 
                                       23
<PAGE>
General Electric had entered into or consummated a change of control on or prior
to April 1, 1998, based on the Merger Consideration, upon consummation of the
Merger MEDIQ would have been entitled to $6,437,994. Pursuant to the Letter
Agreement, MEDIQ has acknowledged that it believes that, based on the accuracy
of the representations described below, it will be owed $4,052,876 upon
consummation of the Merger, while the Company has acknowledged that MEDIQ will
be owed $3,218,997. The Company's belief is based on the fact that $3,218,997 is
50% of the amount that MEDIQ would have been entitled to if the Company and
General Electric had entered into or consummated a change of control on or prior
to April 1, 1998. The Merger Agreement provides for the payment on the Effective
Date of the Merger by General Electric (i) to MEDIQ of an amount equal to
$3,218,997 and (ii) to the Escrow Agent of an amount equal to $833,879, to be
held pursuant to the Escrow Agreement. In a letter agreement among the Company
and MEDIQ, the parties agreed to submit such dispute to binding arbitration
pursuant to the terms of the MEDIQ Agreement to determine the amount MEDIQ
and/or the holders of outstanding shares of Common Stock on the Effective Date
will receive pursuant to the Escrow Agreement.
 
    Under the terms of the Letter Agreement, MEDIQ also released the Company
from any further obligations under the MEDIQ Agreement, contingent upon the
receipt of the MEDIQ Payment and subject to the representations of the Company
and General Electric that such parties did not affirmatively delay any such
change of control transaction and that a description (provided to MEDIQ) of the
parties' discussions with respect to the Merger was materially correct and not
misleading. In connection with the arbitration of the dispute over whether MEDIQ
is owed $4,052,876 or $3,218,997, MEDIQ has advised the Company that it has
concerns as to the accuracy of such representations and that MEDIQ will require
discovery with respect to that issue. MEDIQ has not specified the nature of its
concerns and, in depositions taken in connection with the arbitration
proceedings referenced herein, MEDIQ's Chief Executive Officer and its outside
counsel have testified that they knew of no facts to suggest that the
representations are untrue or that the description is inaccurate. While the
Company believes that the representations are accurate, MEDIQ may nevertheless
claim that they are not accurate and demand that the full amount of $6,437,994
be paid to MEDIQ upon consummation of the Merger. Although the Company believes
that any such claim would be without merit, there is no assurance, if such a
claim is asserted, that the Company will prevail on the issue whether resolved
in the arbitration proceeding or otherwise; however, the ultimate resolution of
this issue will have no effect on the amount of the Per Share Merger
Consideration nor will it affect the Company's or General Electric's obligations
under the Merger Agreement. It is unlikely that the amount MEDIQ is entitled to
receive will be finally resolved before the Merger is consummated. Should MEDIQ
ultimately obtain a final judgment against the Company that it is owed more than
the sum of the MEDIQ Payment and the Escrow Payment, the Company would be
responsible for payment of that excess amount.
 
    ESCROW PAYMENT
 
    As described above, as additional consideration for the Merger, at the
Effective Date General Electric will deposit $833,879 (the "Escrow Payment")
into an account maintained by the Paying Agent, and pursuant to the terms of the
Escrow Agreement, the Paying Agent will be instructed to distribute the Escrow
Payment in full to either MEDIQ and/or the holders of outstanding shares of
Common Stock as determined immediately prior to the Effective Date (or some
combination thereof) in accordance with either an agreement between the
Committee and MEDIQ regarding such funds, or in the absence of such an
agreement, upon the order of the arbitrator(s) upon completion of the
arbitration proceedings regarding the Escrow Payment.
 
    The Committee will initially consist of Mr. Puls, President and Chief
Executive Officer of the Company, Mr. Rauch, Chairman of the Board, and Dr.
Salen, Vice Chairman and Secretary of the Board. The Committee will represent
the interests of the former shareholders of the Company and will speak for and
on behalf of such shareholders with respect to all matters involving the Escrow
Payment and Escrow Agreement. All of the expenses (including legal fees and
costs) of the Committee occurring prior to the
 
                                       24
<PAGE>
Effective Date with respect to the arbitration or the Escrow Agreement shall be
paid by the Company. All of the expenses (including legal fees and costs) of the
Committee occurring on or after the Effective Date with respect to the
arbitration or the Escrow Agreement shall be paid out of the Escrow Payment,
prior to any disbursement of such funds by the Paying Agent. Any fees and
expenses incurred by the Paying Agent in satisfying its duties and obligations
under the Escrow Agreement shall be paid out of the Escrow Payment, prior to any
disbursement of such funds by the Paying Agent.
 
    The Escrow Agreement provides that the Escrow Payment may be invested by the
Escrow Agent with verbal instructions from time to time by the Committee in
investment instruments collateralized and/or a direct obligation of the U.S.
Government or its agencies. In the case of commercial paper, rating of the
commercial paper may not be less than A1/P1.
 
    In the event that all or a portion of the Escrow Payment is awarded or
distributed to the Committee on behalf of the holders of Common Stock as of the
Effective Date, all amounts so distributed shall be payable to such holders as
follows: each share of Common Stock representing a former shareholder interest
shall be entitled to receive an amount equal to (i) the amount of Escrow Payment
awarded or distributed to the Committee on behalf of the holders of Common Stock
as of the Effective Date, divided by (ii) the number of shares of Common Stock
outstanding as of the Effective Date. Such contingent rights will not be
evidenced by any certificate and may not be assigned (except by operation of
law). As of the Record Date, 3,009,395 shares of Common Stock were outstanding.
If the number of shares of outstanding Common Stock remains the same on the
Effective Date, the holder of each share of Common Stock could receive up to an
additional $0.277 per share if all of the Escrow Payment is awarded or
distributed to the Committee on behalf of the former holders of Common Stock.
 
STOCK OPTIONS
 
    As of the close of business on the Record Date, there were an aggregate of
380,200 Outstanding Options at a weighted average exercise price of $3.51 per
share. In connection with the Merger, each of the options to purchase Common
Stock granted under (i) the Company's 1992 Stock Incentive Plan that is
outstanding as of the Effective Date and (ii) the Stock Option Agreement dated
as of December 11, 1996 between the Company and Mr. Puls (the "Puls Agreement"),
whether or not then vested, exercisable or effective, shall, by action of the
Board or a duly authorized committee thereof, under the terms of the 1992 Stock
Incentive Plan and the agreements evidencing the options granted thereunder or
the Puls Agreement, as applicable, and without any action on the part of the
holder thereof, vest and become effective and exercisable solely for the Per
Share Merger Consideration and the contingent right to receive from the
Surviving Corporation a per share amount equal to the per share amount, if any,
received by each former holder of Common Stock under the Escrow Agreement. Prior
to the Effective Date, each of the holders of Outstanding Options shall be
offered the opportunity to enter into a Cancellation Agreement with the Company
wherein, upon the Effective Date, they will receive (i) cash from the Surviving
Corporation in an amount equal to the product of (A) the number of shares of the
Common Stock subject to such Outstanding Options and (B) the amount, if any, by
which the Per Share Merger Consideration exceeds the exercise or strike price
per share of Common Stock subject to such outstanding option immediately prior
to the Effective Date and (ii) the contingent right to receive from the
Surviving Corporation a per share amount equal to the per share amount, if any,
received by each former holder of Common Stock under the Escrow Agreement;
provided that if such amount is equal to or less than zero, such Outstanding
Option shall be deemed canceled and terminated.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    In considering the recommendations of the Board with respect to the Merger,
shareholders should be aware that certain members of the Board and the
management of the Company have certain interests in the Merger that are
different from, or in addition to, the interests of shareholders generally.
 
                                       25
<PAGE>
    For information with respect to beneficial ownership of Common Stock by
management and members of the Board, which Common Stock will be subject to
exchange for the Per Share Merger Consideration and a pro rata share of the
Escrow Payment, if any, upon consummation of the Merger, see "COMPANY
CAPITALIZATION--OWNERSHIP OF COMMON STOCK."
 
    Certain directors of the Company, their direct family members, or accounts,
companies and trusts under their discretion control 49% of the Common Stock and
they have committed, pursuant to the Shareholders' Agreement, to vote all of
their combined Common Stock in favor of the Merger Agreement. See "SHAREHOLDERS'
AGREEMENT."
 
    The Company and Mr. Puls, President and Chief Executive Officer of the
Company and a director of the Company, have entered into a bonus agreement,
dated December 20, 1996, and amended by letter agreement dated May 15, 1998,
wherein Mr. Puls will receive a bonus of $307,500 upon the consummation of the
Merger. The Company and Mr. Hoefert, the Vice President and Chief Financial
Officer of the Company, have entered into a bonus agreement, dated September 29,
1997, wherein Mr. Hoefert will receive a bonus of $150,000 upon the consummation
of the Merger.
 
    In addition, Mr. Puls and Mr. Hoefert are parties to letter agreements with
the Company regarding their employment, wherein they are entitled to certain
severance payments upon termination of their employment with the Company. With
respect to Mr. Puls, upon consummation of the Merger, Mr. Puls' letter agreement
with the Company will be amended to provide that: (i) if the employment of Mr.
Puls is terminated by the Company for any reason other than cause (as defined in
the agreement), then the Company must pay, within five business days after the
date of such termination, a lump-sum severance payment to Mr. Puls equal to the
pro rata portion of Mr. Puls' base salary (A) for the period beginning on the
date of such termination and ending on the twenty-month anniversary of the
Effective Date if such termination occurs on or before the eight-month
anniversary of the Effective Date; or (B) for the period beginning on the date
of such termination and ending on the first-year anniversary of such termination
if such termination occurs after the eight-month anniversary of the Effective
Date. If at any time following the sixtieth day after the Effective Date, Mr.
Puls chooses voluntarily to terminate his employment, the Company will pay to
Mr. Puls, within five business days after the date of such termination, a lump
sum payment equal to the pro rata portion of Mr. Puls' base salary for the
period beginning on the date of such termination and ending on the first-year
anniversary of such termination.
 
    In addition to the agreement discussed above, if (i) at any time after the
Effective Date and before the eight-month anniversary of the Effective Date, the
Company terminates Mr. Puls' employment other than for cause or (ii) if at any
time following the sixtieth day after the Effective Date and before the eight-
month anniversary of the Effective Date Mr. Puls chooses to voluntarily
terminate his employment, the Company will pay to Mr. Puls, within five business
days after the date of such termination, a lump sum payment equal to $56,000.
 
    With respect to Mr. Hoefert, if his employment is terminated by the Company
within six months following a "change of control" of the Company (as defined in
such agreement), then InnoServ must pay Mr. Hoefert a severance payment by the
continuation of his then current monthly salary and continued participation in
the Company's medical and insurance plans for six months after such termination.
 
    In connection with the Merger, each of the options to purchase Common Stock
granted under (i) the Company's 1992 Stock Incentive Plan that is outstanding as
of the Effective Date and (ii) the Puls Agreement, whether or not then vested,
exercisable or effective, shall, by action of the Board or a duly authorized
committee thereof, under the terms of the 1992 Stock Incentive Plan and the
agreements evidencing the options granted thereunder or the Puls Agreement, as
applicable, and without any action on the part of the holder thereof, vest and
become effective and exercisable solely for the Per Share Merger Consideration
and the contingent right to receive from the Surviving Corporation a per share
amount equal to the per share amount, if any, received by each former holder of
Common Stock under the Escrow Agreement. Prior to the Effective Date, each of
the holders of Outstanding Options shall be offered the
 
                                       26
<PAGE>
opportunity to enter into a Cancellation Agreement with the Company wherein,
upon the Effective Date, they will receive cash from the Surviving Corporation
in an amount equal to the product of (i) the number of shares of Common Stock
subject to such Outstanding Options and (ii) the amount, if any, by which the
Per Share Merger Consideration exceeds the exercise or strike price per share of
Common Stock subject to such outstanding option immediately prior to the
Effective Date; provided that if such amount is equal to or less than zero, such
outstanding option shall be deemed canceled and terminated. Under the
Cancellation Agreements described herein, the holders of such Outstanding
Options will also be entitled to receive from the Surviving Corporation a per
share amount equal to the per share amount, if any, received by each former
holder of Common Stock under the Escrow Agreement. Of the 380,200 Outstanding
Options outstanding as of the Record Date, the directors and/or executive
officers of the Company hold Outstanding Options to purchase 257,200 shares of
Common Stock and upon the cancellation thereof in accordance with the terms of
the Merger Agreement will result in cash payments to such persons of at least
$126,028.
 
    Pursuant to the Merger Agreement, General Electric also agreed to indemnify
each current and former officer, director or employee of the Company against all
investigations, actions, suits, proceedings, judgments, costs, fines, amounts
paid in settlement, losses, expenses (including, without limitation, reasonable
attorneys' fees and ancillary related costs), claims, damages or liabilities,
whether civil, criminal, administrative or investigative, arising in whole or in
part out of, or based in whole or in part on, any matter existing or occurring
at or prior to the Effective Date or out of the transactions contemplated by the
Merger Agreement.
 
MANNER OF CONVERTING SHARES
 
    The conversion of shares of Common Stock into the Per Share Merger
Consideration will occur at the Effective Date automatically by operation of
law, without any action on the part of the holder thereof and without regard to
the date on which certificates formerly representing shares of Common Stock are
physically surrendered, or on which the Per Share Merger Consideration is
delivered to former shareholders of the Company. From and after the Effective
Date, each Certificate formerly representing shares of Common Stock (other than
(i) shares held by General Electric or Sub, (ii) shares held by any Company
Subsidiary, (iii) shares held by any General Electric Subsidiary, and (iv)
Dissenting Shares in respect of which appraisal rights are properly exercised
and perfected) shall be converted into the right to receive the Per Share Merger
Consideration and the contingent right to receive the pro rata portion of the
Escrow Payment, if any, in each case, without interest.
 
    At the Effective Date each share of Common Stock owned by any Company
Subsidiary, General Electric or any General Electric Subsidiary shall be
canceled without conversion or without payment of consideration and shall cease
to exist. On or as soon as practicable after the Effective Date, the Letter of
Transmittal setting forth the manner of exchanging Certificates for the Per
Share Merger Consideration will be delivered by the Paying Agent to each holder
of Common Stock as determined immediately prior to the Effective Date. Upon
surrender to the Paying Agent of the Certificate(s), together with a properly
completed Letter of Transmittal, the holder of such Certificate(s) shall be
entitled to immediately receive the Per Share Merger Consideration with respect
to each share formerly represented by such Certificate(s).
 
    If a Certificate has been stolen or destroyed, the registered holder thereof
will be entitled to receive the Per Share Merger Consideration upon delivery to
the Paying Agent of an affidavit to such effect and posting of a bond in a
customary amount as indemnity against any third party claim with respect to such
shares. In the event that a transfer of shares of Common Stock prior to the
Effective Date was not reflected on the Company's stock transfer records, the
transferee may be required, as a condition to exchange, to present the
certificate representing such shares together with all documents required to
evidence and effect such transfer and payment of applicable transfer taxes or
evidence that any applicable stock transfer taxes have been paid. It is
anticipated that the Paying Agent will mail the Per Share Merger
 
                                       27
<PAGE>
Consideration to each former shareholder of the Company who has complied with
the foregoing procedures as soon as practicable but in no event later than seven
business days after such compliance.
 
CONDITIONS TO THE MERGER
 
    The obligations of the Company and General Electric to consummate the Merger
are subject to fulfillment or waiver of the following conditions: (i) approval
of the Merger Agreement by the shareholders of the Company; (ii) the expiration
or termination of the waiting period under the HSR Act and the absence of any
order by any governmental entity restraining, enjoining or prohibiting the
Merger; (iii) the performance in all material aspects of the agreements of each
party, respectively under the Merger Agreement and the receipt by each party of
certificates from an officer of the other party to such effect; (iv) the
representations and warranties contained in the Agreement of each party,
respectively, being correct and true as of the Effective Date (except where the
failure to be so true, individually or in the aggregate with other such
failures, would not have a Parent Material Adverse Effect or a Company Material
Adverse Effect, respectively, as such terms are defined in the Merger
Agreement), and the receipt by each party of certificates from an officer of the
other party to such effect; and (v) the receipt by General Electric of an
opinion of counsel to the Company.
 
REGULATORY APPROVAL
 
    General Electric and the Company filed notification of the Merger and report
forms with the DOJ and the FTC on December 24, 1997 and December 30, 1997,
respectively. On January 29, 1998, the DOJ made a "second request" of the
Company and General Electric for additional documentation regarding the HSR Act
filing. As described in "DESCRIPTION OF THE PROPOSED MERGER--BACKGROUND OF AND
REASONS FOR THE MERGER," the parties had multiple meetings with the DOJ
regarding the HSR Act issues and the DOJ contacted certain third parties in
investigating the potential Merger. On July 14, 1998, General Electric and the
Company received notice that the FTC has granted early termination of the
waiting period under the HSR Act. Pursuant to the terms of the Merger Agreement,
General Electric and the Company entered into the Side Agreement wherein General
Electric agreed to pay the Company $1,200,000 if the DOJ did not grant
termination or expiration of the waiting period under the HSR Act prior to the
later of June 22, 1998 or the date of the meeting of the shareholders of the
Company approving the Merger. Since early termination has been granted, no
amount is payable by General Electric to the Company under the Side Agreement.
 
AMENDMENT; TERMINATION
 
    The Merger Agreement may be amended by written agreement of each of the
parties before or after approval by the Company's shareholders by action of each
party's board of directors (in the case of the Company and Sub) and by any vice
president (in the case of General Electric), provided that, if after such
shareholder approval, applicable law requires shareholder approval of an
amendment, the amendment will not be valid without such approval. The Merger
Agreement may be terminated and the Merger abandoned before the Effective Date
(i) by mutual written consent of the Company, duly authorized by its Board and
General Electric by any vice president; (ii) by either party if the other fails
to comply in any material respect with any of its respective covenants or
agreements contained in the Merger Agreement, provided that the other party is
not in material breach of any representation, warranty, covenant or other
agreement contained in the Merger Agreement; (iii) by either party if there has
been a material breach at the time when made by the other party, provided that
the terminating party is not in material breach of any representation, warranty,
covenant or other agreement contained in the Merger Agreement; (iv) by either
party if the shareholders of the Company shall not approve the Merger at the
Special Meeting; (v) by either party if the Merger has not been effected on or
prior to the close of business on September 30, 1998, except that such right to
terminate shall not be available to a party whose willful and material failure
to fulfill any obligation of the Merger Agreement has been the cause of, or
resulted in, the failure of the
 
                                       28
<PAGE>
Merger to be effected; (vi) by either party if any court or other governmental
entity shall have issued an order, decree or ruling or taken any other action
permanently enjoining, restraining or otherwise prohibiting the transactions
contemplated by the Merger Agreement; (vii) by either party if any order or
directive has a material adverse effect on the business, operations or financial
condition of the Surviving Corporation; (viii) by the Company by written notice
to General Electric if the Board in good faith determines that a proposal by a
third party to purchase 35% or more of the assets of the Company, or which
results in such third party controlling 35% or more of the beneficial interests
of shares of the Common Stock (a "Superior Proposal"), will be more favorable to
its shareholders than the Merger and General Electric has not exercised its
right to match such proposal; or (ix) by General Electric if the Board shall
have failed to recommend the Merger to the Company's shareholders, or shall have
modified, in a manner adverse to General Electric, or withdrawn its
recommendation of the Merger to the Company's shareholders as being advisable
and fair to and in the best interests of the Company and its shareholders. If a
termination is caused by (i) a breach of a representation or warranty of the
Company, (ii) a failure by the Company to comply in any material respect with
any of its covenants or agreements contained in the Merger Agreement, (iii) a
failure by the shareholders to vote in favor of the Merger, (iv) notification to
General Electric of the Board's determination that a third party's proposal is
more favorable than the Merger, or (v) failure of the Board to recommend the
Merger, the Company is required to pay General Electric $550,000.
 
NO SOLICITATION
 
    Prior to the Effective Date or the earlier termination of the Merger
Agreement, the Company has agreed not to directly or indirectly, take, nor
authorize or permit any of its subsidiaries or its or their officers, directors,
employees, representatives, investment bankers, financial advisors, attorneys,
accountants or other agents or affiliates, to take any action to (i) encourage,
solicit or initiate the submission of any tender or exchange offer, any bona
fide written proposal for a merger, consolidation or other transaction which
contemplates (A) the acquisition of more than 35% of the assets of the Company
and the Company Subsidiaries taken as a whole or (B) any other agreement that
contemplates the acquisition of beneficial ownership of more than 35% of the
outstanding shares of the Common Stock or any public announcement of a proposal,
plan or intention to do any of the foregoing (a "Business Combination
Proposal"), (ii) enter into any agreement with respect to any Business
Combination Proposal or (iii) participate in any way in discussions or
negotiations with, or furnish any non-public written information to, any person
in connection with, or take any other action to encourage the making of any
proposal that constitutes, or may reasonably be expected to lead to, any
Business Combination Proposal; provided that the Company may (i) participate in
discussions or negotiations with or furnish information to any persons or group
(other than General Electric or an affiliate of General Electric) (a "Third
Party") that makes an unsolicited Business Combination Proposal that the Board
determines (after consultation with its financial advisors) may reasonably be
expected to result in a Superior Proposal, and enter into any confidentiality
agreement or standstill agreement with such Third Party in connection with such
a Business Combination Proposal (provided, that any such information so
furnished or any such confidentiality or standstill agreements so entered into
shall, at the time such information is furnished or such agreement is entered
into, be promptly delivered to General Electric), (ii) comply with Rule 14e-2
promulgated under the Exchange Act with regard to any Business Combination
Proposal (assuming that such Business Combination Proposal includes a tender
offer requiring the Company's response pursuant to such Rule), (iii) fail to
make or withdraw or modify its recommendation regarding the Merger to its
shareholders if there exists a Business Combination Proposal that is a Superior
Proposal or if the Board determines, in good faith and after consultation with
independent counsel, that such action is required to discharge properly its
fiduciary duties, or (iv) after terminating the Merger Agreement, enter into an
agreement with respect to or recommend to its shareholders a Business
Combination Proposal that is a Superior Proposal.
 
    Notwithstanding the foregoing, the Company may not enter into an agreement
with respect to or recommend to its shareholders a Business Combination Proposal
that is a Superior Proposal or fail to
 
                                       29
<PAGE>
make or withdraw or modify its recommendation to its shareholders if there
exists a Business Combination Proposal that is a Superior Proposal unless (i)
two business days shall have elapsed after delivery to General Electric of a
written notice informing General Electric of the terms and conditions of the
Business Combination Proposal, and (ii) General Electric does not, within such
two business day period, make an offer which the Board determines in good faith
(based on the advice of its financial adviser) to be as favorable to the
Company's shareholders as such Business Combination Proposal.
 
    Additionally, the Company has agreed to promptly advise General Electric of
any request for non-public written information or of any Business Combination
Proposal, or any inquiry with respect to or which appears to be intended to or
could reasonably be expected to lead to any Business Combination Proposal, the
material terms and conditions of such request, Business Combination Proposal or
inquiry, and in the case of a Business Combination Proposal that involves
consideration other than all cash, the identity of the party making such
Business Combination Proposal. The Company also has agreed to keep General
Electric fully informed of the status and details of any such request, Business
Combination Proposal or inquiry.
 
PREFERRED STOCK
 
    Pursuant to the Merger Agreement, on June 5, 1998, a subsidiary of General
Electric purchased 700,000 shares of Series B Preferred Stock of the Company
(the "Preferred Shares") from the Company for $2,800,000. The Company and a
subsidiary of General Electric entered into a registration rights agreement (the
"Registration Rights Agreement") which provides for the registration of the
Preferred Shares upon the fulfillment of certain conditions. A copy of the
Registration Rights Agreement is attached as Appendix IV.
 
    Except as otherwise expressly provided by law, the Preferred Shares do not
have any right to vote for the election of directors or for any other purpose
(including the Merger). The Preferred Shares accrue dividends of $0.32 per share
per annum, beginning six months from the issuance of such shares, whether or not
earned or declared, and such dividends are due and payable semiannually on the
last day of June and December, beginning on the last day of December 1998. Any
dividends not paid when due shall become part of the Liquidation Value (as
hereinafter defined) of each Preferred Share. No dividends or distributions on
Common Stock (other than dividends of Common Stock) shall be issued until all
such Preferred Share dividends are paid and satisfied, and thereafter, the
Preferred Shares shall share in any such dividends or distributions on Common
Stock PARI PASSU to the shares of Common Stock then outstanding as if such
Preferred Shares had been converted immediately prior to the record date of such
dividend or distribution. Upon a liquidation, the Preferred Shares shall be
entitled to receive out of the assets of the Company, before payment on the
Common Stock, an amount equal to $4.00 per share plus any accrued but unpaid
dividends (the "Liquidation Value"). Upon payment of the Liquidation Value, the
Preferred Shares shall have no claim to the remaining assets of the Company.
 
    The Preferred Shares are redeemable by the Company at its option at any time
after issuance at a price equal to the Liquidation Value. Each Preferred Share
is convertible at the option of the holder into one share of Common Stock at any
time, including prior to a redemption, after the earlier of (i) the consummation
of a transaction arising out of a Superior Proposal, or (ii) the later of (A)
September 30, 1998 or (B) the termination of the Merger Agreement. Upon a
conversion, the holder of such converted Preferred Share(s) shall be entitled to
the accrued dividends earned but not yet paid on such Preferred Share(s). The
Company is required to pay such accrued dividends on or before the first
anniversary of the conversion, provided that such dividends shall accrue
interest at a rate of 8.0% per annum from the date of such conversion to the
payment date.

ACCOUNTING TREATMENT
 
    The Merger will be accounted for under the purchase method of accounting, in
accordance with generally accepted accounting principles. Under the purchase
method of accounting, the purchase price of the Company, including direct costs
of the Merger, will be allocated to the tangible assets acquired and liabilities
assumed based on their estimated relative fair market values, with the excess
purchase consideration allocated to intangible assets. The results of General
Electric's operations will include the results of operations of the Company only
from and after the Effective Date.
 
MERGER EXPENSES
 
    The Company will incur the expenses of printing and filing this Proxy
Statement. Each party will pay all other expenses incurred by it incident to the
Merger and carrying out of the transactions contemplated by the Merger
Agreement, except for the filings under the HSR Act which was paid by General
Electric. The Company estimates that the expenses which it will incur in
connection with the Merger for legal, accounting, investment advisory, filing
fees, printing, mailing and other costs, fees and expenses will aggregate
approximately $1,125,000.
 
DEREGISTRATION OF COMMON STOCK
 
    Following consummation of the Merger, the shares of Common Stock will cease
to be registered under the Exchange Act and will cease to be publicly traded.
 
SOURCE AND AMOUNT OF FUNDS
 
    The total amount of funds that will be required to pay shareholders, MEDIQ,
the Escrow Payment and any holders of options pursuant to the Merger Agreement
is approximately $16,300,000. General Electric intends to obtain the funds from
internal sources. In addition, General Electric's payment of $2,800,000 in
return for the Preferred Shares was also obtained from internal sources.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion of the material United States federal income tax
consequences of the Merger is for general information only. It is based on the
Internal Revenue Code of 1986, as amended (the "Code"), existing and proposed
Treasury Regulations and judicial and administrative determinations, all of
which are subject to change at any time, possibly on a retroactive basis. It
does not discuss the state, local or foreign tax consequences of the Merger, nor
does it discuss tax consequences to categories of shareholders that are subject
to special rules, such as foreign persons, tax-exempt organizations, insurance
companies, banks, persons who received their shares of Common Stock as
compensation and dealers in stocks and securities. Tax consequences may vary
depending on the particular status of an investor. No rulings will be sought
from the Internal Revenue Service (the "Service") with respect to the federal
income tax consequences of the Merger.
 
PURCHASE OF SHARES
 
    The receipt of the Per Share Merger Consideration pursuant to the Merger and
the receipt of the contingent right to the Escrow Payment, if any, pursuant to
the Escrow Agreement will be a taxable transaction for United States federal
income tax purposes (and may also be a taxable transaction under applicable
state, local and other income tax laws). In general, for federal income tax
purposes, a shareholder will recognize gain or loss equal to the difference
between his or her adjusted tax basis in his or her shares of Common Stock and
the amount of proceeds received by the shareholder in exchange therefor. The
proceeds include the Per Share Merger Consideration and the fair market value of
the contingent right to receive the Escrow Payment, if any, pursuant to the
Escrow Agreement. Any gain or loss recognized by a shareholder pursuant to the
Merger generally will be capital gain or loss if the shares of Common Stock were
held as capital assets and will be long-term capital gain or loss if, on the
Effective Date, the shares of Common Stock were held for more than one year.
Since the Common Stock is publicly traded, the contingent right to receive the
Escrow Payment does not permit a shareholder to use the installment method to
report any gain recognized in the Merger for purposes of federal income tax law.
Furthermore, since the Escrow Agreement may not expire within one year of its
effective date, the contingent right to receive the Escrow Payment could be
governed by the federal income tax laws applicable to contingent payment debt
instruments. As such, the contingent right to receive the Escrow Payment may
cause a shareholder to accrue interest income in the form of original issue
discount. SINCE TREATMENT FOR FEDERAL INCOME TAX PURPOSES OF A RIGHT TO RECEIVE
CONTINGENT PAYMENTS, SUCH AS THE ESCROW PAYMENT, IS UNCERTAIN, SHAREHOLDERS
SHOULD CONSULT THEIR TAX ADVISORS AS TO THE TIMING AND AMOUNT OF ANY INCOME OR
GAIN ATTRIBUTABLE TO THE RECEIPT OF THE CONTINGENT RIGHT TO RECEIVE THE ESCROW
PAYMENT (AND TO THE RECEIPT OF THE ESCROW PAYMENT ITSELF, IF ANY) PURSUANT TO
THE ESCROW AGREEMENT.
 
BACKUP WITHHOLDING
 
    Under the Code, the receipt of the Per Share Merger Consideration and Escrow
Payment, if any, may be subject, under certain circumstances, to "backup
withholding" at a 31% rate. This withholding generally applies only if the
shareholder (i) fails to furnish his or her social security or other taxpayer
identification number ("TIN") within a reasonable time after the request
therefor, (ii) furnishes an incorrect TIN, (iii) is notified by the Service that
he or she has failed to report properly interest or dividends, or (iv) fails,
under certain circumstances, to provide a certified statement, signed under
penalty of perjury, that the TIN provided is the correct number and that he or
she is not subject to backup withholding. Any amount withheld from a payment to
a shareholder under the backup withholding rules is allowable as a credit
against such shareholder's federal income tax liability, provided that the
required information is furnished to the Service. Corporations and certain other
entities described in the Code and Treasury Regulations are exempt from such
withholding if their exempt status is properly established. Shareholders should
consult
 
                                       32
<PAGE>
their tax advisors as to their qualification for exemption from withholding and
the procedure for obtaining such exemption.
 
GENERAL
 
    The foregoing discussion may not be applicable to shareholders who are
subject to special treatment under United States federal income tax law or to
holders of shares of Common Stock acquired upon the exercise of employee stock
options or otherwise as compensation.
 
    THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
FOR GENERAL INFORMATION ONLY. SHAREHOLDERS ARE URGED TO CONSULT WITH THEIR TAX
ADVISORS TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO THEM (INCLUDING THE
APPLICATION AND EFFECT OF STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS) OF
THE MERGER.

series, to establish from time to time the number of shares to be included in
each such series, to fix the designations, powers, preferences and rights of the
shares of each such series and any qualifications, limitations or restrictions
thereof, and to increase or decrease the number of shares of any such series
(but not below the number of shares of such series then outstanding). The Board
may authorize and issue preferred stock with voting or conversion rights that
could adversely affect the voting power or other rights of the holders of Common
Stock. Pursuant to the Merger Agreement, on May 15, 1998, the Board agreed to
authorize and issue 700,000 shares of the Preferred Shares. See "DESCRIPTION OF

                       RIGHTS OF DISSENTING SHAREHOLDERS
 
    If the Merger is consummated, holders of Common Stock who object to the
Merger may be entitled to have the "fair market value" of their shares at the
Effective Date (exclusive of any element of value arising from the
accomplishment or expectation of the Merger) judicially determined and paid to
them by complying with the provisions of Chapter 13 of the California General
Corporation Law ("Chapter 13"). However, because the Common Stock is traded in
the Nasdaq National Market, shareholders of the Company who object to the Merger
may vote against approval and adoption of the Merger Agreement at the Special
Meeting but will not be entitled to dissenters' rights if the Merger is
consummated over their objections unless the holders of five percent or more of
the outstanding shares of Common Stock make appropriate demands under Chapter
13.
 
    The following is a brief summary of Chapter 13, which sets forth the
procedures for dissenting from the Merger and demanding statutory dissenters'
rights. This summary is qualified in its entirety by reference to Chapter 13,
the text of which is attached hereto as Appendix VI. Appendix VI should be
reviewed carefully by any holder who wishes to exercise statutory dissenters'
rights or who wishes to preserve the right to do so, because failure to comply
with the procedures set forth in Chapter 13 will result in the loss of
dissenters' rights.
 
    Not later than the date of the Special Meeting, a shareholder of the Company
who desires to exercise his or her statutory dissenters' rights must make a
written demand upon the Company (addressed and delivered to the Secretary of the
Company at 320 Westway, Suite 520, Arlington, Texas 76018) to purchase and pay
to the shareholder in cash the "fair market value" of all or any portion of the
shares of Common Stock held of record by the shareholder. Such written demand
must contain a statement of what such shareholder claims to be the fair market
value of those shares as of the day before the first public announcement of the
proposed Merger. This statement of fair market value constitutes an offer by the
shareholder to sell such shares at such price. Such written demand must be in
addition to and separate from any proxy or vote against the proposal to approve
the Merger. Voting against the Merger will not constitute the written demand for
payment of the fair market value in cash of any shares that is required by
Chapter 13. The written demand must be executed by or for the shareholders of
record, fully and correctly, as such shareholder's name appears on the
certificate representing such shareholder's shares of Common Stock.
 
    Pursuant to the provisions of Chapter 13, holders of Common Stock desiring
to exercise their statutory dissenters' rights must affirmatively vote against
approval of the Merger Agreement and the transactions contemplated thereby at
the Special Meeting. Abstaining from voting or failing to vote on the proposal
to approve the Merger Agreement will not constitute a vote against the Merger
Agreement and the Merger for the purpose of establishing dissenters' rights. Any
shareholder who desires to exercise dissenters' rights should (i) either (A)
execute and return a proxy card in the respective form accompanying this Proxy
Statement, specifying that his or her shares are to be voted against the
approval and
 
                                       36
<PAGE>
adoption of the Merger Agreement, or (B) attend the Special Meeting in person
and vote against approval and adoption of the Merger Agreement and (ii) not
later than the date of the Special Meeting make written demand upon the Company
for the purchase of the shares and payment to the shareholder in cash of the
shares' fair market value. If a holder of Common Stock returns a signed proxy
but does not specify a vote against approval and adoption of the Merger
Agreement or a direction to abstain from voting on the approval of the Merger
Agreement, the proxy will be voted FOR approval and adoption of the Merger
Agreement and the Merger, which will waive such holder's dissenters' rights.
 
    If the Merger Agreement is approved and the holders of five percent or more
of the outstanding shares of Common Stock have made appropriate demands under
Chapter 13, the Company will have 10 days after such approval to send to those
shareholders who have made a demand upon the Company for the fair market value
of their shares by the date of the Special Meeting and who have voted against
the Merger Agreement written notice of such approval, which must be accompanied
by a copy of Chapter 13, a statement of the price determined by the Company to
represent the fair market value of the dissenting shares, and a brief
description of the procedure to be followed if a shareholder desires to exercise
dissenters' rights. In order to preserve his or her dissenters' rights, a
shareholder must, within 30 days after the date on which the notice of approval
of the Merger Agreement is mailed, make written demand upon the Company for the
purchase of dissenting shares, specifying their number, and for payment to such
shareholder in cash of the fair market value of such dissenting shares. Within
the same 30-day period, the dissenting shareholder must also surrender to the
Company at the office designated in the notice of approval of the Merger
Agreement, the certificates representing the dissenting shares to be stamped or
endorsed with a statement that they are dissenting shares or to be exchanged for
certificates of appropriate denomination so stamped or endorsed. Any shares of
Common Stock that are transferred before their submission for endorsement will
lose their status as dissenting shares.
 
    If the Company denies that shares surrendered are dissenting shares, or if a
shareholder fails to agree with the Company upon the fair market value of his or
her dissenting shares, then the dissenting shareholder must, within six months
after the notice of the approval of the Merger Agreement is mailed, either file
a complaint with the Superior Court of the County of Los Angeles requesting that
the Court make such determinations, or intervene in any pending action brought
by any other dissenting shareholder. If such a complaint is not filed or such
intervention in a pending action is not made within the specified six-month
period, the dissenting shareholder will lose his or her dissenters' rights. No
shareholder will be entitled to receive the fair market value of his or her
shares of Common Stock as a consequence of the exercise of dissenters' rights
unless the Merger is consummated.

    Mr. Sandler served as Vice President and Chief Financial Officer of InnoServ
from May 1, 1997 to September 29, 1997. Mr. Sandler was not directly compensated

Mr. Sandler spent at InnoServ at an hourly rate based on MEDIQ's cost plus
travel and other related expenses. For services provided by Mr. Sandler during

    EMPLOYMENT AGREEMENTS
 
    InnoServ has letter agreements with Mr. Puls and Mr. Hoefert which provide
that if the employment of the executives is terminated by InnoServ for any
reason other than cause (as defined in the agreement), then InnoServ must pay a
severance payment by continuing the executive's then current monthly salary and
continued participation in InnoServ's medical and insurance plans for twelve
months in the case of Mr. Puls and six months in the case of Mr. Hoefert. The
agreements also contain a two year covenant not to compete following termination
of employment.
 
    The agreements with Mr. Puls and Mr. Hoefert each also provide that, in the
event of termination of the executive's employment with InnoServ without cause
within six months following a "change of control" of InnoServ (as defined in
such agreement), the executive will receive a severance payment as provided for
above and, in the case of Mr. Puls, a one-time payment equivalent to his prior
year's bonus. The agreements also provide for immediate vesting of all the
executives' stock options upon such change of control.
 
    Upon consummation of the Merger, Mr. Puls' letter agreement with the Company
will be amended to eliminate the termination and severance payments described
above and to provide that if the employment of Mr. Puls is terminated by the
Company for any reason other than cause (as defined in the agreement), then the
Company must pay, within five business days after the date of such termination,
a lump sum severance payment to Mr. Puls, equal to the pro rata portion of Mr.
Puls' base salary (i) for the period beginning on the date of such termination
and ending on the twenty-month anniversary of the Effective Date if such
termination occurs on or before the eight-month anniversary of the Effective
Date or (ii) for the period beginning on the date of such termination and ending
on the first-year anniversary of such termination if such termination occurs
after the eight-month anniversary of the Effective Date. If at any time
following the sixtieth day after the Effective Date, Mr. Puls chooses
voluntarily to terminate his employment, the Company will pay to Mr. Puls,
within five business days after the date of such termination, a lump sum payment
equal to the pro rata portion of Mr. Puls' base salary for the period beginning
on the date of such termination and ending on the first-year anniversary of such
termination.
 
    In addition to the agreement discussed above, if (i) at any time after the
Effective Date and before the eight-month anniversary of the Effective Date, the
Company terminates Mr. Puls' employment other than for cause or (ii) if at any
time following the sixtieth day after the Effective Date and before the eight-
month anniversary of the Effective Date, Mr. Puls chooses to voluntarily
terminate his employment, the
 
                                       41
<PAGE>
Company will pay to Mr. Puls, within five business days after the date of such
termination, a lump sum payment equal to $56,000.
 
    Mr. Puls has an agreement with InnoServ that provides for a one-time bonus
ranging from $300,000 to $400,000, depending on the Sale Price (as defined in
such agreement), in the event of a Sale of the Company (as defined in such
agreement), provided that he is a full time employee (subject to requirements
defined in the agreement) in good standing on the closing of such a Sale of the
Company. Upon consummation of the Merger, Mr. Puls' agreement with the Company
will be amended to provide for a one-time bonus of $307,500.
 
    Mr. Hoefert has an agreement with InnoServ providing for a one-time bonus
ranging from $150,000 to $250,000, depending on the Sale Price (as defined in
the agreement), in the event of a Sale of the Company (as defined in such
agreement), provided that he is a full time employee (subject to requirements
defined in the agreement) in good standing on the closing of such a Sale of the
Company. Under the terms of such agreement, upon consummation of the Merger, Mr.

behalf of its GE Medical Systems business ("PARENT"), Diamond Merger Sub, Inc.,
a California corporation and a wholly owned subsidiary of a wholly owned

    WHEREAS, Parent and the Company desire to effect a business combination by
means of the merger of Sub with and into the Company;
 
    WHEREAS, the respective Boards of Directors of Sub and the Company have

their respective shareholders to consummate, the merger of Sub with and into the
Company (the "MERGER"), upon the terms and subject to the conditions set forth
herein;
 
    WHEREAS, concurrently with the execution and delivery of this Agreement and
as an inducement to Parent to enter into this Agreement, certain shareholders of
the Company (the "PRINCIPAL HOLDERS") have entered into an agreement with
Parent, in the form attached hereto as EXHIBIT A (the "SHAREHOLDERS'
AGREEMENT"), pursuant to which the Principal Holders have agreed, among other
things, to vote their Shares (as defined in SECTION 3.1) in favor of the Merger;
 
    NOW, THEREFORE, in consideration of the foregoing premises and the
respective representations, warranties and agreements contained herein, the
parties hereto agree as follows:
 
                                   ARTICLE I
                                   THE MERGER
 
    Section 1.1  THE MERGER.  Upon the terms and subject to the conditions set
forth in this Agreement and in accordance with the California General

of Sub shall thereupon cease, and the Company, as the surviving corporation in
the Merger (the "SURVIVING CORPORATION"), shall by virtue of the Merger continue
its corporate existence under the laws of the State of California.
 
    Section 1.2  EFFECTIVE DATE OF THE MERGER.  The Merger shall become
effective at the date and time (the "EFFECTIVE DATE") when a properly executed
copy of the Agreement of Merger of Sub into the Company (the "AGREEMENT OF
MERGER"), attached as Exhibit A.1, and appropriate officers' certificates, in
the form as is required by the CGCL, are duly filed with and accepted by the
Secretary of State of the State of California, which filing shall be made by the
Company and Sub as soon as practicable on the Closing Date (as defined in
SECTION 3.10), or at such time thereafter as is provided in such certificate.
 
                                   ARTICLE II

    prior to the Effective Date (other than (i) Shares held by Parent or Sub,
    (ii) Shares held by any corporation, partnership, joint venture, or other
    entity in which the Company (A) owns directly or indirectly, 50% or more of
    the outstanding voting securities or equity interests other than the Shares
    held by the InnoServ Technologies, Inc. Employee Stock Purchase Plan or (B)

    $16,000,000 minus (II) (a) the MEDIQ Payment (as defined in SECTION 3.7),
    and (b) the Escrow Payment (as defined in SECTION 3.8), DIVIDED by (B) the

    Section 3.2  PAYING AGENT AND SURRENDER OF CERTIFICATES.
 
        (a) Prior to the Effective Date, the Company and Parent shall appoint
    The Bank of New York or such other bank or trust company selected by Parent
    and reasonably acceptable to the Company, and having a place of business in
    New York City, as paying agent (the "PAYING AGENT") for purposes of this
    Agreement.
 
        (b) Immediately after the Effective Date, Parent shall cause the
    Surviving Corporation to deposit with the Paying Agent, for the benefit of
    the persons entitled to payment hereunder, funds equal to the remainder of
    (A) $16,000,000 MINUS (B) (I) the MEDIQ Payment, and (II) the Escrow Payment
    (the "STOCK PAYMENT FUND"). The Paying Agent shall invest the Stock Payment
    Fund as Parent directs, in direct obligations of the United States of
    America, obligations for which the full faith and credit of the United
    States of America is pledged to provide for the payment of all principal and
    interest, commercial paper obligations receiving the highest rating from
    either Moody's Investors Services, Inc. or Standard & Poor's Corporation, or
    certificates of deposit, bank repurchase agreements or banker's acceptances
    of commercial banks with capital exceeding $25,000,000,000. The Stock
    Payment Fund shall not be used for any other purpose except as provided in
    this Agreement.
 
        (c) On or as soon as practicable after the Effective Date, the Surviving
    Corporation shall cause the Paying Agent to mail to each person who was a
    record holder of Company Common Stock at the Effective Date (individually, a
    "HOLDER" and collectively, the "HOLDERS") (other than Parent, Sub, the
    Company, Parent Subsidiaries or Company Subsidiaries), a form of letter of
    transmittal (which shall specify that delivery shall be effected, and risk
    of loss and title to the Certificates shall pass, only upon proper delivery
    of the Certificates to the Paying Agent and shall otherwise be in such form
    and have such provisions as Parent and the Company may reasonably specify)
    and instructions for use in effecting the surrender for payment of
    Certificates that immediately prior to the Effective Date represented
    Company Common Stock. Upon surrender of a Certificate to the Paying Agent,
    together with a duly executed letter of transmittal, the holder of the
    Certificate shall be entitled to receive immediately, in exchange therefor
    cash in an amount equal to the product of the number of Shares previously
    represented by such Certificate or Certificates surrendered and the Per
    Share Merger Consideration.
 
    No interest will be paid or accrued on the cash payable upon the surrender
    of the Certificates. If a payment is to be made to a person other than the
    person in whose name a surrendered Certificate is registered, it shall be a
    condition of payment that (x) the Certificate so surrendered shall be
    properly endorsed or otherwise in proper form for transfer and that (y) the
    person requesting such payment shall pay any transfer or other taxes
    required by reason of the payment to a person other than the registered
    holder of the Certificate surrendered or establish to the satisfaction of
    Parent or the Paying Agent that such tax has been paid or is not applicable.
    After the Effective Date, until surrendered in accordance with the
    provisions of this SECTION 3.2, a Certificate shall represent only the right
    to receive the Per Share Merger Consideration in cash multiplied by the
    number of Shares previously evidenced by such Certificate, without any
    interest thereon and the contingent right to receive additional
    consideration pursuant to the Escrow Agreement.
 
        (d) On or after the one hundred eightieth day following the Effective
    Date, the Surviving Corporation may by written request require the Paying
    Agent to remit to the Surviving Corporation (on terms reasonably
    satisfactory to the Paying Agent) (a "REFUND REQUEST") any funds held in the
    Stock Payment Fund that (i) have not been applied prior to any such Refund
    Request to make payments in respect of Certificates or (ii) are not required
    at the time of such Refund Request to permit the Paying Agent to make
    payment to the holders of any Certificates that have been surrendered by the
    date of such Refund Request for which payment is pending, but with respect
    to which no such payment has yet been made at the time of such Refund
    Request. Any holders of Shares who have not theretofore complied with
    SECTION 3.2(C) shall thereafter look only to the Surviving
 
                                       3

    Corporation (subject to abandoned property, escheat or other similar laws)
    for payment of their claim for the Per Share Merger Consideration, without
    any interest thereon, but shall have no greater rights against the Surviving
    Corporation than may be accorded to general creditors of the Surviving
    Corporation under California law.
 
        (e) The Surviving Corporation shall pay all charges and expenses,
    including those of the Paying Agent, in connection with the exchange of cash
    for the Shares.
 
        (f) Neither Parent, Sub nor the Company shall be liable to any holder of
    Shares for any Per Share Merger Consideration delivered to a public official
    pursuant to any applicable abandoned property, escheat or similar law.
 
        (g) The Paying Agent and Surviving Corporation shall be entitled to
    deduct and withhold from the Per Share Merger Consideration otherwise
    payable pursuant to this Agreement to any holder of Shares such amounts as
    the Paying Agent or Surviving Corporation is required to deduct and withhold
    with respect to the making of such payment under the Internal Revenue Code
    of 1986, as amended (the "CODE"), or any provision of state, local or
    foreign tax law. To the extent that amounts are so withheld by the Paying
    Agent or Surviving Corporation, such withheld amounts shall be treated for
    all purposes of this Agreement as having been paid to the holder of the
    Shares in respect of which such deduction and withholding was made by the
    Paying Agent or Surviving Corporation.
 
        (h) In the event any Certificates shall have been lost, stolen or
    destroyed, the Paying Agent shall deliver in exchange for such lost, stolen
    or destroyed Certificates the Per Share Merger Consideration as may be
    required pursuant to SECTION 3.2 upon (i) the making of an affidavit of that
    fact by the holder thereof, and (ii) if required by Parent, the posting by
    such person of a bond in customary amount as indemnity against any claim
    that may be made against it with respect to such Certificate.
 
            (i) Effective as of the date hereof, the Shareholders' Committee
       (the "SHAREHOLDERS' COMMITTEE") will be constituted and will be composed
       of Michael Puls, President and Chief Executive Officer of the Company,
       Dudley Rauch, Chairman of the Board of the Company and a third Holder to
       be appointed by Mr. Puls and Mr. Rauch, each of whom has agreed to serve
       as a member of the Shareholders' Committee. The Shareholders' Committee
       will continue in existence until all of its duties under this Agreement
       and the Escrow Agreement are discharged.
 
            (ii) The Shareholders' Committee will have full and irrevocable
       power and authority to act for and in the name of, and as the agent for,
       the Holders and the holders of Outstanding Options (as defined in SECTION
       3.6) (collectively, the "FORMER HOLDERS") without giving notice to the
       Former Holders or obtaining their consent, in connection with all matters
       relating to the Escrow Payment and to enforce, pursue, compromise, settle
       and waive the rights of the Former Holders relating to the Escrow
       Payment, subject to the specific limitations set forth below, and to do
       all such things and execute all such instruments as it deems necessary,
       proper or desirable in order to promote the interests of the Former
       Holders, including, without limitation, to settle any dispute with MEDIQ
       Incorporated ("MEDIQ") relating to the Escrow Agreement; provided that in
       no event will the Shareholders' Committee have the power or authority to
       settle any dispute among the Holders with respect to their individual
       proportion of the Escrow Payment as disbursed by the Escrow Agent (as
       defined in the Escrow Agreement), if any, to be received by any Former
       Holder. Any determination as to what is in the interests of the Former
       Holders made by the Shareholders' Committee in good faith will be
       conclusive and binding on all Former Holders and their successors and
       assigns.
 
           (iii) The Shareholders' Committee (A) may rely on any document
       believed by it to be genuine and to have been signed or presented by the
       proper person, (B) need not investigate any fact or matter stated in such
       document, and (C) may act through its attorneys and agents and will not
       be responsible for the misconduct or negligence of any agent appointed
       with due care. The
 
                                       4
                                     A-I-10
<PAGE>
       Shareholders' Committee may consult with counsel and the advice or
       opinion of such counsel as to matters of law will be full and complete
       authorization and protection in respect of any action taken, omitted, or
       suffered by it under this Agreement in good faith and in accordance with
       the advice or opinion of such counsel.
 
            (iv) Any action to be taken by the Shareholders' Committee may be
       taken by a majority of its members present at a meeting of the
       Shareholders' Committee (a quorum being present), including any meeting
       held by means of conference telephone or similar communications equipment
       by means of which all persons participating in the meeting can hear each
       other, or by written consent of all members of the Shareholders'
       Committee. If a member of the Shareholders' Committee resigns, dies, or
       becomes incapacitated, the remaining members of the Shareholders'
       Committee will appoint a successor member, notwithstanding the absence of
       a quorum. If all three positions on the Shareholders' Committee become
       simultaneously vacant, successors may be appointed by the written action
       of the Former Holders of a majority of the shares of Company Common Stock
       and the Outstanding Options as of the Effective Date, except that if such
       vacancy results from the simultaneous resignation of members of the
       Shareholders' Committee, the resigning member(s) may appoint successors.
       The number of members of the Shareholders' Committee will be three.
       Unless he resigns, each member of the Shareholders' Committee will serve
       until the duties of the Shareholders' Committee have been fully
       discharged. At any meetings of the Shareholders' Committee, two members
       will constitute a quorum.
 
            (v) The Shareholders' Committee and its members will not be liable
       for any action they take or omit to take in good faith that they believe
       to be authorized or within their rights or powers. All out-of-pocket
       expenses reasonably incurred on or after the Effective Date by the
       Shareholders' Committee (including attorneys' and professionals' fees) in
       discharging the duties of the Shareholders' Committee under this
       Agreement will be paid out of the Escrow Payment pursuant to the terms of
       the Escrow Agreement. The Surviving Corporation shall indemnify, defend
       and hold harmless each member of the Shareholders' Committee (and their
       respective successors, assigns, heirs, executors. administrators and
       representatives) against any and all costs, expenses, claims, damages or
       liabilities arising out of or based upon any action or inaction of the
       Shareholders' Committee under or in connection with this Agreement or the
       Escrow Agreement.
 
    Section 3.3  DISSENTING SHARES.  Notwithstanding anything in this Agreement
to the contrary, Shares which are issued and outstanding immediately prior to
the Effective Date and which are held by shareholders who have properly
exercised appraisal rights with respect thereto under Section 1301 of the CGCL
(the "DISSENTING SHARES") shall not be converted into the right to receive the
Per Share Merger Consideration as provided in SECTION 3.1 but the holders of
Dissenting Shares shall be entitled to receive such payment as shall be
determined pursuant to Chapter 13 of the CGCL; provided, that if any such holder
shall have failed to perfect or shall withdraw or lose the right to appraisal
and payment under the CGCL, then such holder shall forfeit the right of dissent
and each such holder's Shares shall thereupon be deemed to have been converted
as of the Effective Date into the right to receive the Per Share Merger
Consideration, without any interest thereon, as provided in SECTION 3.1, and
such Shares shall no longer be Dissenting Shares. The Company shall give Parent
prompt notice of any demands for payment under Section 1301 of the CGCL received
by the Company. Except as required by applicable law, prior to the Effective
Date, the Company shall not, except with the prior written consent of Parent,
make any payment with respect to, or settle or offer to settle, any such
demands.
 
    Section 3.4  CONVERSION OF SUB SECURITIES.  At the Effective Date, each
share of common stock, par value $0.01 per share, of Sub issued and outstanding
immediately prior to the Effective Date shall be converted, by virtue of the
Merger and without any action on the part of the holder thereof, into one fully
paid and nonassessable share of the common stock, par value $0.01 per share, of
the Surviving Corporation.

    Section 3.5  SHAREHOLDERS TO HAVE NO FURTHER RIGHTS.  At and after the
Effective Date, the holder of a Certificate shall cease to have any rights as a
shareholder of the Company, except for (i) the right to surrender such
Certificate in exchange for the amount of Per Share Merger Consideration and the
contingent right to receive additional consideration pursuant to the Escrow
Agreement to which such holder is entitled under this Agreement and (ii) the
rights available under the CGCL for Dissenting Shares. In no event shall the
holder of a Certificate have any rights as a shareholder of the Surviving
Corporation.
 
    Section 3.6  STOCK OPTIONS.  At the Effective Date, each of the options to
purchase Company Common Stock granted under (i) the Company's 1992 Stock
Incentive Plan, as amended (the "STOCK OPTION PLAN") that is outstanding as of
the Effective Date and (ii) the Stock Option Agreement dated as of December 11,
1996 between the Company and Michael G. Puls (the "PULS AGREEMENT" and
collectively with the options outstanding under the Stock Option Plan, the
"OUTSTANDING OPTIONS"), whether or not then vested, exercisable or effective,
shall, by action of the Board of Directors of the Company or a duly authorized
Committee thereof, under the terms of the Stock Option Plan and the agreements
evidencing the options granted thereunder or the Puls Agreement, as applicable,
and without any action on the part of the holder thereof, vest and become
effective and exercisable solely for the Per Share Merger Consideration (without
interest). Prior to the Effective Date, each holder of Outstanding Options shall
be offered the right to execute an agreement, substantially in the form attached
hereto as Exhibit B, to cancel such Outstanding Options. Immediately after the
Effective Date and in no event later than the first payment to a Holder pursuant
to SECTION 3.2, Parent shall cause the Surviving Corporation to pay to each
holder of an Outstanding Option who executes such an agreement, in consideration
for such cancellation, an amount in cash (less applicable withholding taxes, if
any) equal to the amount and in the manner set forth in the agreement attached
hereto as Exhibit B; provided that if such amount is equal to or less than zero,
such Outstanding Option shall be deemed canceled and terminated. For purposes of
this SECTION 3.6, each of the Company, Sub and Parent agree that each option
listed on SECTION 5.2 of the Company's Disclosure Schedule (as hereinafter
defined), unless such option is exercised or expires in accordance with the
provisions of Stock Option Plan or Puls Agreement prior to the Effective Date,
is an Outstanding Option.
 
    Section 3.7  MEDIQ PAYMENT.  Immediately after the Effective Date, and in no
event later than the first payment to a Holder pursuant to SECTION 3.2, the
Parent shall cause the Surviving Corporation to pay to MEDIQ in cash, without

to an account designated by MEDIQ an amount equal to $3,218,997 (the "MEDIQ
PAYMENT.")
 
    Section 3.8  ESCROW PAYMENT.  Immediately after the Effective Date, Parent
shall cause the Surviving Corporation to deposit with the Paying Agent, an
amount, in cash, equal to $833,879 (the "ESCROW PAYMENT"), to be disbursed by
the Paying Agent pursuant to the terms and conditions of the escrow agreement
attached hereto as Exhibit C (the "ESCROW AGREEMENT"). In the event that the
parties to the Escrow Agreement shall provide written notice to the Parent, duly
executed by each such party prior to the Effective Date that such parties have
reached agreement with respect to the disbursement of the Escrow Payment, the
Company, Parent and Sub each hereby agrees to amend this Agreement to reflect
such agreement.
 
    Section 3.9  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  After the close of
business on the Effective Date, the stock transfer books of the Company shall be
closed and no transfer of Shares shall be made thereafter. In the event that,
after the Effective Date, Certificates are presented to the Surviving
Corporation, they shall be forwarded to the Paying Agent and be subject to the
provisions of SECTION 3.2.
 
    Section 3.10  CLOSING.  Unless this Agreement is terminated and the

                                   ARTICLE IV
                    REPRESENTATIONS AND WARRANTIES OF PARENT
 
    Parent represents and warrants to the Company as follows:
 
    Section 4.1  ORGANIZATION AND QUALIFICATION.  Parent is a corporation duly
organized, validly existing and in good standing under the laws of the State of
New York and has all requisite corporate power and authority to own and operate
its properties and assets and to carry on its business as it is now being
conducted. Parent is duly qualified as a foreign corporation, and is in good
standing, in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities make such qualification
necessary, except where the failure to be so qualified and in good standing will
not have a Parent Material Adverse Effect (as defined in SECTION 4.7).
 
    Section 4.2  AUTHORITY RELATIVE TO THIS AGREEMENT.  Parent has the requisite
corporate power and authority to enter into this Agreement and to carry out its
obligations hereunder and to consummate the transactions contemplated hereby.
The execution, delivery and performance of this Agreement by Parent and the
consummation of the transactions contemplated hereby by Parent have been duly
authorized by all necessary corporate action on the part of Parent. This
Agreement has been duly executed by Parent and constitutes a valid and binding
obligation of Parent enforceable in accordance with its terms except as
enforcement may be limited by bankruptcy, insolvency or other laws affecting the
enforcement of creditors' rights generally. Neither the execution and delivery
of this Agreement nor the consummation of the transactions contemplated hereby
will (a) conflict with or violate the charter or by-laws of Parent or (b) result
in any breach or constitute a default (with or without notice or lapse of time,
or both) or give rise in others to any rights of termination, cancellation or
acceleration under any agreement, indenture, contract, loan agreement, license,
franchise, permit, order, decree, concession, lease, instrument, judgment,
statute, law, ordinance, rule or regulation applicable to Parent or any Parent
Subsidiary or its or their respective assets, other than, in the case of clause
(b) only, breaches, defaults, violations and losses of rights that would not
have a Parent Material Adverse Effect and the laws and regulations referred to
in the next sentence. Except in connection, or in compliance, with the
provisions of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (which filing has been made) (the "HSR ACT"), the Securities Exchange
Act of 1934, as amended (the "EXCHANGE ACT"), and the corporation, securities or
blue sky laws or regulations of the various states, no filing or registration
with, or authorization, consent or approval of, any governmental or regulatory
body or authority is necessary for the consummation by Parent of the Merger or
the other transactions contemplated by this Agreement, except where the failure
to make any such filing or registration or obtain any such authorization,
consent or approval would not have a Parent Material Adverse Effect or prevent
or materially delay consummation of the Merger.
 
    Section 4.3  INFORMATION IN PROXY STATEMENT.  None of the information
supplied by Parent or Sub to be included or incorporated by reference in the
proxy statement of the Company (the "PROXY STATEMENT") required to be mailed to
the shareholders of the Company in connection with the Merger will at the time
of the mailing of the Proxy Statement and any amendments or supplements thereto,
and at the time of the Company Meeting (as defined in SECTION 8.2) to be held in
connection with the Merger, 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 therein, in light of the circumstances under which
they are made, not misleading.

    Section 4.4  FINANCIAL ADVISOR.  No broker, finder or investment banker is
entitled to any brokerage, finder's or other fee or commission in connection
with the Merger or the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of Parent.
 
    Section 4.5  PARENT NOT AN INTERESTED SHAREHOLDER.  Neither Parent nor any
of its affiliates is an "Interested Party" pursuant to Section 1203 of CGCL.
 
    Section 4.6  FINANCING.  Parent and Sub have available to them funds
necessary to satisfy their respective obligations hereunder.
 
    Section 4.7.  PARENT ADVERSE EFFECT.  For purposes of this Agreement,

that is materially adverse to the business, operations or financial condition of
Parent and the Parent Subsidiaries taken as a whole, other than changes,
effects, circumstances or events: (i) affecting Parent's industry generally,
(ii) resulting from general economic conditions, or (iii) resulting from the
transactions contemplated by this Agreement or the announcement thereof.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company represents and warrants to Parent and Sub that, except as set
forth in the disclosure schedule delivered by the Company to Parent and Sub on

standing, in each jurisdiction where the character of its properties owned or
held under lease or the nature of its activities makes such qualification

or regulations of the various states, no filing or registration with, or
authorization, consent or approval of, any governmental or regulatory body or
authority is necessary for the consummation by the Company of the Merger or the

    Subsidiaries with their employees.
 
        (f) No provision of this SECTION 8.4 shall create any third-party
    beneficiary rights in any employee or former employee (including any
    beneficiary or dependent thereof) of Parent, the Company, any Company
    Subsidiary, or any of their affiliates in respect of continued employment
    (or resumed employment) for any specified period of any nature or kind
    whatsoever.
 
        (g) In the event this Agreement is terminated prior to the Effective
    Date, without the prior written consent of the Company, neither the Medical
    Systems division of Parent nor Sub shall for a period of one year after the
    date on which this Agreement is terminated, directly or indirectly solicit
    for employment, any person or persons employed by the Company or any Company
    Subsidiary at any time prior to the time this Agreement is terminated. The
    foregoing restriction on solicitation of employment shall not be deemed to
    apply to unsolicited inquiries concerning possible employment which are
    received by Parent, Sub or any Parent Subsidiary from or on behalf of such
    person, nor shall it apply to general solicitations of employment not
    specifically directed toward any such employees of the Company or any
    Company Subsidiary.
 
    Section 8.5  INDEMNIFICATION.
 
        (a) From and after the Effective Date, to the fullest extent permitted
    under the CGCL, Parent shall indemnify, defend and hold harmless each
    current and former officer, director or employee of the Company or any
    Company Subsidiary (together with their respective successors, assigns,
    heirs, executors, administrators and representatives, the "INDEMNIFIED
    PARTIES") against all investigations, actions, suits, proceedings,
    judgments, costs, fines, amounts paid in settlement, losses, expenses
    (including, without limitation, reasonable attorneys' fees and ancillary
    related costs), claims, damages or liabilities, whether civil, criminal,
    administrative or investigative, arising in whole or in part out of, or
    based in whole or in part on, any matter existing or occurring at or prior
    to the Effective Date or out of the transactions contemplated by this
    Agreement. In the event of any such claim, action, suit, proceeding or
    investigation (whether arising before or after the Effective Date), (i) any
    counsel retained by the Indemnified Parties for any period after the
    Effective Date shall be reasonably satisfactory to Parent, (ii) after the
    Effective Date, Parent shall pay the reasonable fees and expenses of such
    counsel, promptly after statements therefor are received, and (iii) Parent
    shall, and shall cause the Surviving Corporation to, cooperate in the
    defense of any such matter; provided, however, that Parent shall not be
    liable for any settlement effected without its written consent (which
    consent shall not be unreasonably withheld or delayed). The Indemnified
    Parties as a group may retain only one law firm to represent them with
    respect to any single action unless there is, under applicable standards of
    professional conduct, a conflict between the positions of any two or more
    Indemnified Parties. The indemnity agreements of Parent in this SECTION
    8.5(A) shall extend, on the same terms to, and shall inure to the benefit of
    and shall be enforceable by, each person or entity who controls, or in the
    past controlled, any present or former director, officer or employee of the
    Company or any of the Company Subsidiaries.
 
        (b) Parent agrees that all rights to indemnification existing in favor
    of the current or former directors, officers or employees of the Company or
    any Company Subsidiary under the Company's Articles of Incorporation, as
    amended, and By-Laws as in existence on the date hereof arising in whole or
    in part out of, or based in whole or in part on, any matter existing or
    occurring at or prior to
 
                                       21

    the Effective Date, shall survive the Merger and shall continue in full
    force and effect in respect of claims made during a period of ten years from
    the Effective Date, and Parent shall guaranty the obligations of the
    Surviving Corporation in respect thereof.
 
        (c) The Surviving Corporation shall honor and fulfill in all respects
    the obligations of the Company pursuant to the indemnification agreements
    with the Company's directors and executive officers existing at the date
    hereof and Parent shall guaranty the obligations of the Surviving
    Corporation in respect thereto. True and correct copies of such
    indemnification agreements have been furnished to Parent.
 
        (d) This SECTION 8.5 is intended for the benefit of, and shall be
    enforceable by, the persons referenced herein and their respective heirs
    and/or personal representatives, and shall be binding upon Parent and its
    successors and assigns.
 
    Section 8.6  ANTITRUST MATTERS.  The Company and Parent have filed
notifications under the HSR Act in connection with the Merger and the
transactions contemplated hereby. The Company, Parent and Sub shall use their
reasonable efforts to respond as promptly as practicable to all inquiries and
requests received from any State Attorney General or other governmental
authority in connection with antitrust matters relating to the transactions
contemplated by this Agreement.
 
    Section 8.7  REASONABLE EFFORTS: NOTIFICATION.
 
        (a) Subject to the terms and conditions of this Agreement, including
    SECTION 8.8 each of the parties hereto agrees to cooperate with each other
    and use reasonable efforts to take, or cause to be taken, all actions and to
    do, or cause to be done, in each case consistent with the fiduciary duties
    of their respective Boards of Directors, all things necessary, proper or
    advisable (i) under applicable laws and regulations to consummate and make
    effective the transactions contemplated by this Agreement as soon as
    reasonably practicable, including to obtain all necessary waivers, consents
    and approvals, to effect all necessary registrations and filings (including,
    but not limited to, filings with all applicable Governmental Entities) and
    (ii) to lift any injunction or other legal bar to the Merger as soon as
    reasonably practicable (and, in such case, to proceed with the Merger as
    expeditiously as possible); provided, however, that notwithstanding anything
    to the contrary in this Agreement, neither Parent nor Sub shall be in any
    way obligated to take any action in order to obtain the termination of the
    waiting period under the HSR Act, except as provided in EXHIBIT D.
 
        (b) Parent shall give prompt notice to the Company, and the Company

    covenants, conditions or agreements contained in this Agreement not to be

    and (ii) any failure of Parent or the Company, as the case may be, to comply
    with or satisfy any of its covenants, conditions or agreements to be
    complied with or satisfied by it hereunder; provided, that the delivery of
    any notice pursuant to this SECTION 8.7 shall not limit or otherwise affect
    the remedies available hereunder to the party receiving such notice.
 
    Section 8.8  NO SOLICITATION.
 
        (a) Prior to the Effective Date or the earlier termination of this
    Agreement pursuant to SECTION 10.1 the Company shall not, directly or
    indirectly, take (nor shall the Company authorize or permit any Company
    Subsidiary or its or their officers, directors, employees, representatives,
    investment bankers, financial advisors, attorneys, accountants or other
    agents or affiliates, to take) any action to (i) encourage, solicit or
    initiate the submission of any Business Combination Proposal (as defined
    below), (ii) enter into any agreement with respect to any Business
    Combination Proposal or (iii) participate in any way in discussions or
    negotiations with, or furnish any non-public written information to, any
    person in connection with, or take any other action to encourage the making
    of

                                     A-I-28
<PAGE>
    any proposal that constitutes, or may reasonably be expected to lead to, any
    Business Combination Proposal; provided, that the Company may (i)
    participate in discussions or negotiations with or furnish information to
    any persons or group (other than Parent or an affiliate of Parent) (a "THIRD
    PARTY") that makes an unsolicited Business Combination Proposal that the
    Board of Directors of the Company determines (after consultation with its
    financial advisors) may reasonably be expected to result in a Superior
    Proposal (as defined below), and enter into any confidentiality agreement or
    standstill agreement with such Third Party in connection with such a
    Business Combination Proposal (provided, that any such information so
    furnished or any such confidentiality or standstill agreements so entered
    into shall, at the time such information is furnished or such agreement is
    entered into, be promptly delivered to Parent), (ii) comply with Rule 14e-2
    promulgated under the Exchange Act with regard to any Business Combination
    Proposal (assuming that such Business Combination Proposal includes a tender
    offer requiring the Company's response pursuant to such Rule), (iii) fail to
    make or withdraw or modify its recommendation referred to in SECTION 8.2 if
    there exists a Business Combination Proposal that is a Superior Proposal or
    if the Board of Directors of the Company determines, in good faith and after
    consultation with independent counsel, that such action is required to
    discharge properly its fiduciary duties, or (iv) after terminating this
    Agreement in accordance with Section 10.1(e) enter into an agreement with
    respect to or recommend to its shareholders a Business Combination Proposal
    that is a Superior Proposal. Any actions permitted under, and taken in
    compliance with this SECTION 8.8, shall not be deemed a breach of any other
    covenant or agreement of the Company contained in this Agreement.
 
        (b) Notwithstanding the foregoing, the Company may not enter into an
    agreement with respect to or recommend to its shareholders a Business
    Combination Proposal that is a Superior Proposal or fail to make or withdraw
    or modify its recommendation referred to in SECTION 8.2 if there exists a
    Business Combination Proposal that is a Superior Proposal unless (i) two
    business days shall have elapsed after delivery to Parent of a written
    notice informing Parent of the terms and conditions of the Business
    Combination Proposal, and (ii) Parent does not, within such two business day
    period, make an offer which the Board of Directors of the Company determines
    in good faith (based on the advice of its financial adviser) to be as
    favorable to the Company's shareholders as such Business Combination
    Proposal.
 
        (c) For purposes of this Agreement, "BUSINESS COMBINATION PROPOSAL"
    shall mean, with respect to the Company, the commencement of any tender or
    exchange offer, any bona fide, written proposal for a merger, consolidation
    or other Business Combination involving the shareholders of the Company, the
    Company or any Company Subsidiary or any public announcement of a proposal,
    plan or intention to do any of the foregoing. "BUSINESS COMBINATION" means
    any transaction which contemplates (i) the acquisition of more than 35% of
    the assets of the Company and the Company Subsidiaries taken as a whole or
    (ii) any other agreement that contemplates the acquisition of beneficial
    ownership of more than 35% of the outstanding shares of the Company's Common
    Stock. "SUPERIOR PROPOSAL" shall mean, with respect to the Company, any
    Business Combination Proposal, for which any required financing is supported
    by reasonable commitments, that the Board of Directors of the Company in
    good faith determines (after consultation with its financial advisors) will
    be more favorable to its shareholders than the Merger.
 
        (d) In addition to the obligations of the Company set forth in SECTION
    8.8(A) and SECTION 8.8(B), the Company shall promptly advise Parent of any
    request for non-public written information or of any Business Combination
    Proposal, or any inquiry with respect to or which appears to be intended to
    or could reasonably be expected to lead to any Business Combination
    Proposal, the material terms and conditions of such request, Business
    Combination Proposal or inquiry, and in the case of a Business Combination
    Proposal that involves consideration other than all cash, the identity of
    the party making such Business Combination Proposal. The Company shall keep
    Parent fully informed of the status and details of any such request,
    Business Combination Proposal or inquiry.

        (e) During the period from the date of this Agreement through the
    Effective Date, the Company shall not terminate, amend, modify or waive any
    provision of any confidentiality or standstill agreement in connection with
    a potential business combination to which it or any of its Subsidiaries is a
    party. During such period, the Company shall use commercially reasonable
    efforts to enforce, to the fullest extent permitted under applicable law,
    the provisions of any such agreements if and to the extent the executive
    officers of the Company have knowledge of a breach of the terms thereof,
    including, but not limited to, by obtaining injunctions to prevent any
    breaches of such agreements and to enforce specifically the terms and
    provisions thereof in any court of the United States of America or of any
    state having jurisdiction.

preferred shares in form and substance substantially similar to the terms of the
Preferred Stock Designation, and the Parent or its designee shall purchase such

rights and "piggy back" rights to Parent or its designee upon the reasonable

                         SHAREHOLDERS AGREEMENT

     SHAREHOLDERS AGREEMENT, dated as of May ___, 1998, by and among General
Electric Company, a New York corporation acting through its GE Medical
Systems division ("Parent"), on the one hand, and the persons set forth in
the signature page hereto in their capacities as shareholders of InnoServ
Technologies, Inc., a California corporation (the "Company") (collectively,
the "Shareholders" and individually, a "Shareholder"), on the other hand.

     WHEREAS, concurrently herewith, Parent, a subsidiary of a subsidiary of
Parent and the Company are entering into an Agreement and Plan of Merger (the
"Merger Agreement"; capitalized terms used without definition herein having
the meanings ascribed thereto in the Merger Agreement);

     WHEREAS, each Shareholder has sole, or together with such Shareholder's
spouse as necessary, has complete voting and dispositive power and/or full
voting power as to the aggregate number of shares of Common Stock, par value
$.01 per share, of the Company (the "Company Common Stock") set opposite such
Shareholder's name on SCHEDULE I attached hereto, whether as certificated
shares in the name of such Shareholder or held in brokerage accounts in the
name of such Shareholder; such shares of Company Common Stock, as such shares
may be adjusted by any stock dividend, stock split, recapitalization,
combination or exchange of shares, merger, consolidation, reorganization or
other change or transaction of or by the Company, being referred to herein as
the "Shares";

     WHEREAS, approval of the Merger Agreement by the Company's shareholders
is a condition to the consummation of the Merger;

     WHEREAS, as a condition to its entering into the Merger Agreement,
Parent has required that the Shareholders agree, and the Shareholders have
agreed, to enter into this Agreement;

     WHEREAS, the Shareholders have been informed that the Board of Directors
of the Company has approved the Merger Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

     Section 1. AGREEMENT TO VOTE, RESTRICTIONS ON DISPOSITIONS, ETC.

          During the term of the Agreement:

          a.  Each of the Shareholders hereby agrees to attend the Company
     Meeting, in person or by proxy, and to vote (or cause to be voted) all
     Shares, and any other voting securities of the Company, whether issued
     heretofore or hereafter, that such person owns or has the right to vote,
     for approval and adoption


                                     A-I-39

<PAGE>

     of the Merger Agreement and the Merger, such agreement to vote to apply
     also to any adjournment or adjournments of the Company Meeting. Each
     Shareholder agrees not to grant any proxies or enter into any voting
     agreement or arrangement inconsistent with this Agreement.

          b.  Each of the Shareholders hereby agrees to vote (or cause to be
     voted) all Shares, and any other voting securities of the Company,
     whether issued heretofore or hereafter, that such person owns or has the
     right to vote, against (i) any merger (other than the Merger),
     consolidation, combination, sale of assets, reorganization,
     recapitalization, dissolution, liquidation or other business combination
     or similar transaction involving the Company or its Subsidiaries,
     securities or assets (including any Business Combination Proposal) which
     is not approved in writing by Parent or (ii) any amendment of the
     Company's articles of incorporation or by-laws or other proposal
     involving the Company or any Subsidiary, which amendment or proposal
     would in any manner impede, frustrate, prevent or nullify the Merger,
     the Merger Agreement or any of the transactions contemplated by the
     Merger Agreement or which could result in any of the conditions to the
     Company's obligations under the Merger Agreement not being fulfilled.

          c.  Each of the Shareholders hereby agrees that, without the prior
     written consent of Parent, such Shareholder shall not, directly or
     indirectly, sell, offer to sell, grant any option for the sale of or
     otherwise, pledge, transfer, tender or dispose of, or enter into any
     agreement to sell, pledge (other than existing margin call pledge
     agreements with respect to Shares held in brokerage accounts in the name
     of a Shareholder), transfer, tender or dispose of, any Shares and any
     other voting securities of the Company, issued heretofore or hereinafter
     that such person owns or has the right to vote; PROVIDED, HOWEVER, that
     Parent shall consent to any such sale, pledge, transfer or disposition
     of any such Shares or other voting securities by and between
     Shareholders.

          d.  Each of the Shareholders, solely in his capacity as a
     shareholder, hereby agrees not to directly or indirectly take (nor shall
     such Shareholder authorize or permit any representative, investment
     banker, financial advisor, attorney, accountant or other agent of such
     Shareholder to take) any action to (i) encourage, solicit or initiate
     the submission of any Business Combination Proposal or (ii) participate
     in any way in discussions or negotiations with, or furnish any
     non-public written information to, any person in connection with, or
     take any other action to encourage the making of any proposal that
     constitutes, or may reasonably be expected to lead to, any Business
     Combination Proposal; provided, that with respect to Shareholders who
     serve as officers or directors of the Company, such Shareholders acting
     solely in their capacity as officers or directors may (i) participate in
     discussions or negotiations with or furnish information to any Third
     Party that makes an unsolicited Business Combination Proposal that the
     Board of Directors of the Company determines (after consultation with
     its financial advisors) may reasonably be expected to result in a


                                     A-I-40

<PAGE>

     Superior Proposal, and permit the Company to enter into any
     confidentiality agreement or standstill agreement with such Third Party
     in connection with such a Business Combination Proposal, (ii) take all
     steps necessary to cause the Company to comply with Rule 14e-2
     promulgated under the Exchange Act with regard to any Business
     Combination Proposal (assuming that such Business Combination Proposal
     includes a tender offer requiring the Company's response pursuant to
     such Rule), (iii) take the steps necessary as directors to fail to make
     or withdraw or modify the Board of Directors' recommendation referred to
     in SECTION 8.2 of the Merger Agreement if there exists a Business
     Combination Proposal that is a Superior Proposal or if such director
     determines, in good faith and after consultation with independent
     counsel, that such action is required to discharge properly his
     fiduciary duties, or (iv) if the Company terminates the Merger Agreement
     in accordance with Section 10.1(e) thereof, cause the Company to enter
     into an agreement with respect to or recommend to its shareholders a
     Business Combination Proposal that is a Superior Proposal.

          e.  Each of the Shareholders agrees to promptly notify Parent in
     writing of the nature and amount of any acquisition by such Shareholder
     of any voting securities of the Company acquired by such Shareholder
     hereinafter.

     Section 2.  REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS.  Each of
the Shareholders, as to himself, herself or itself, as an individual
shareholder, represents and warrants to Parent as follows: (a) this Agreement
has been duly executed and delivered by such Shareholder; (b) assuming the
due authorization, execution and delivery of this Agreement by Parent, this
Agreement constitutes the valid and binding agreement of such Shareholder
enforceable against such Shareholder in accordance with its terms, except as
may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium and other similar laws of general application which may affect the
enforcement of creditors' rights generally and by general equitable
principles; (c) the shares of Company Common Stock listed next to the name of
such Shareholder on SCHEDULE I hereto are the only voting securities of the
Company owned (beneficially or of record) by such Shareholder and are held by
such Shareholder either as certificated shares or in brokerage accounts in
the name of such Shareholder free and clear of all liens, charges,
encumbrances, restrictions and commitments of any kind; and (d) the execution
and delivery of this Agreement by such Shareholder does not conflict with any
agreement, order or other instrument binding upon such Shareholder, nor
requires any regulatory filing or approval.

     Section 3. FURTHER ASSURANCES.  Each party shall execute and deliver
such additional instruments and other documents and shall take such further
actions as may be necessary or appropriate to effectuate, carry out and
comply with all of their obligations under this Agreement. Without limiting
the generality of the foregoing, none of the parties hereto shall enter into
any agreement or arrangement (or alter, amend or terminate any existing
agreement or arrangement) if such action would materially impair the ability
of any party to effectuate, carry out or comply with all the terms of this
Agreement.

and warrants to each Shareholder as follows: (a) each of this Agreement and
the Merger Agreement has been duly executed and delivered by a duly
authorized officer or employee of Parent; and (b) assuming the due
authorization, execution and delivery of this Agreement by the Company and
the Shareholders, each of this Agreement and the Merger Agreement constitutes
a valid and binding agreement of Parent, enforceable against Parent in
accordance with its terms, except as may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws of general
application which may affect the enforcement of creditors' rights generally
and by general equitable principles.

     Section 5. EFFECTIVENESS AND TERMINATION. It is a condition precedent to
the effectiveness of this Agreement that the Merger Agreement shall have been
executed and delivered and be in full force and effect. This Agreement shall
terminate upon the earliest of (i) the close of business on September 30,
1998, (ii) the Effective Date or (iii) the termination of the Merger

hereof shall survive for 180 days after termination of this Agreement.  Upon

have in respect of any breach by any other party of its or his obligations
hereunder, none of the parties hereto shall have any further obligation or
liability hereunder.

     interest thereon, as provided in SECTION 7(a), and such Shares shall no
     longer be Dissenting Shares.

          instructions, forward the Escrow Funds, less any fees and expenses
          owed hereunder, to the persons and in the amounts specified in such
          joint instruction.

               (ii)  Unless the Paying Agent has previously received a joint
          written instruction as described in Section 7(f)(i), then upon the
          receipt of written instruction duly executed by (i) the one

          paid out of the Escrow Account prior to the disbursement of any
          Escrow Funds disbursed pursuant to sections (i) through (iii) of
          this Section regardless of whether the

acknowledged that the maximum amount owed to it under the Stock Purchase
Agreement upon consummation of such Merger is $4,052,876. However, as
described in the Letter Agreement, InnoServ believes that MEDIQ is only
entitled to $3,218,997 and that InnoServ's shareholders are entitled to the
$833,879 difference.

     The Merger Agreement provides for the payment on the Effective Date (as
defined in the Merger Agreement) to MEDIQ of $3,218,997 and for the deposit
in escrow of the remaining $833,879.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants set forth below, and for their mutual reliance, MEDIQ, the
Committee and Escrow Agent agree as follows:

     1.   ESCROW DEPOSIT.  On or before the Effective Date, General Electric
is required to cause the Surviving Corporation (as defined in the Merger
Agreement) to deposit the sum of Eight Hundred-Thirty-Three Thousand, Eight
Hundred & Seventy-Nine Dollars ($833,879) (the "Deposit") with Escrow Agent,
by wire transfer, in immediately available funds, to be invested


                                    A-I-55

<PAGE>

promptly, as directed by the Committee, in an interest bearing escrow account
or in one or more investments of the type and quality described on SCHEDULE 1
(such interest bearing account and any other investments in which the Deposit
may be invested being herein collectively referred to as the "Escrow
Account").  The Deposit, together with all interest earned thereon, is herein
referred to as the "Escrow Funds".

     2.   DISBURSEMENT OF ESCROW FUNDS

          (a)  Upon the receipt of a joint written instructions duly executed
     by MEDIQ and each member of the Committee, the Escrow Agent shall, as
     soon as practicable after the receipt of such joint written instructions,
     forward the Escrow Funds, less any fees and expenses owed hereunder, to
     the persons and in the amounts specified in such joint instruction.

          (b)  Unless the Escrow Agent has previously received a joint
     written instruction as described in Section 2(a), then upon the receipt
     of written instruction duly executed by (i) the one arbitrator in the
     case of an arbitration under Section 5.13 of the Stock Purchase
     Agreement, if the parties can agree to an arbitration with one
     arbitrator, or (ii) a majority of the arbitrators in the case of an
     arbitration under Section 5.13 of the Stock Purchase Agreement, if the
     parties cannot agree on an arbitration with a single arbitrator, the
     Escrow Agent shall, 5 business days after the receipt of such order,
     forward the Escrow Funds, less any fees and expenses owed hereunder, to
     the persons specified and in the amounts specified in such written
     instructions.

          (c)  Any Escrow Funds herein awarded to or distributed to the
     Committee by and on behalf of the former shareholders of InnoServ shall
     be distributed among such shareholders in the following manner: each
     Holder (as defined in the Merger Agreement) shall receive an amount
     equal to (i) the amount of Escrow Funds forwarded or disbursed
     hereunder, divided by (ii) the number of shares outstanding as of the
     Effective Date, without interest thereon, in the manner described in
     Section 3.2(c) of the Merger Agreement.

     3.   CONDITIONS OF ESCROW.

          (a)  Escrow Agent, by reason of its consent to and execution of
     this Agreement, for the fees herein specified, hereby agrees to accept
     the foregoing agreement and instructions and to be bound by this
     Agreement in the performance of its duties hereunder. Escrow Agent shall
     not, however, assume any responsibility or liability for any transaction
     between InnoServ and MEDIQ or the Committee and MEDIQ, other than for

     by it in accordance with this Agreement. The duties and responsibilities
     of Escrow Agent shall be limited to those expressly set forth herein.

<PAGE>

          (b)  Escrow Agent shall be under no responsibility in respect of
     the Escrow Account other than faithfully to follow the instructions
     contained herein. Escrow Agent may consult with counsel of its own
     choosing and shall be fully protected in any action taken in good faith,
     in accordance with such consultation. Escrow Agent shall not be required
     to defend any legal proceedings that may be instituted unless requested
     so to do by the Committee and MEDIQ, and shall be indemnified the
     Committee and MEDIQ, jointly and severally, to its satisfaction against
     the cost and expense of such defense. Escrow Agent shall have no
     responsibility for the genuineness or validity of any document or other
     item deposited with Escrow Agent and it shall be fully protected in
     acting in accordance with written instructions to it hereunder and
     believed by Escrow Agent to have been signed by the proper parties.

          (c)  Except for claims, liabilities, judgments, or expenses
     incurred by the parties due to an intentional or negligent act, error or
     omission of Escrow Agent in the performance of its obligations
     hereunder, the Escrow Agent shall be entitled to be protected and held
     harmless from any claims, liabilities, judgments, reasonable attorneys'
     fees, and other expenses of any kind and nature that may be incurred by
     Escrow Agent by reason of its acceptance of, and its good faith
     performance under, this Agreement out of funds in the Escrow Account;
     provided, however, that this indemnification shall not extend to any
     intentional, negligent or reckless act, error or omission of Escrow
     Agent. All of the terms and conditions in connection with Escrow Agent's
     duties and responsibilities, and the rights of the parties or any third
     party, are contained in this Agreement. Escrow Agent is not required to
     be familiar with the provisions of any other instrument or agreement and
     shall not be charged with any responsibility or liability in connection
     with the observance or nonobservance by any person having duties or
     obligations under any such instrument or agreement.

          (d)  The Escrow Agent may resign for any reason upon thirty (30)
     days written notice to MEDIQ and the Committee. Upon the expiration of
     such thirty (30) day notice period, Escrow Agent may deliver all
     Escrowed Funds to any successor escrow agent appointed by MEDIQ and the
     Committee, or if no successor escrow agent has been appointed, then to
     any court of competent jurisdiction. Upon either such delivery, Escrow
     Agent shall be released from any and all liability hereunder.

     4.   TERMINATION.  Notwithstanding any other provision of this Agreement
to the contrary, this Agreement shall terminate, without any further action
on the part of MEDIQ, the Committee or Escrow Agent, upon disbursement in
full of the Escrow Funds in accordance with the terms of this Agreement.

     5.   FEES AND OTHER CHARGES. The fees and other charges for services
rendered by Escrow Agent for ordinary services as contemplated by this
Agreement are set forth on SCHEDULE 2 of this Agreement. All costs and fees
associated with the escrow shall be paid out of the Escrow Account prior to
the disbursement of any Escrow Funds pursuant to Section 2 of this Agreement.
All of the legal costs and fees of the Committee incurred on or after the

                                  BONUS AGREEMENT

     This Bonus Agreement (this "Agreement") is entered into between InnoServ

capacity of Vice President and Chief Financial Officer; and

     WHEREAS, the board of directors of the Company (the "Board of

and the shareholders of the Company that the Company from time to time
investigate strategic alternatives in order to maximize shareholder value; and

     WHEREAS, the Executive is a member of senior management of the Company
and has access to proprietary information pertaining to the business and
operations of the Company; and

     WHEREAS, the Board of Directors has determined that it is in the best
interests of the Company to provide an incentive to the Executive to remain
in the employ of the Company while the Company is investigating such
strategic alternatives;

     NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, the Company and Executive agree as follows:

     1.   Subject to paragraph 2 below, if Executive is a full-time employee

     2.   Executive will not be eligible for benefits hereunder if he

     3.   For purposes of this Agreement, a Sale of the Company shall be

     is used in Section 13(d)(3) of the Securities Exchange Act of 1934.

          c.   For the purposes of calculating the Sale Price of the Company,

     7.   Neither this Agreement nor any right or interest hereunder shall be

invalid, illegal or unenforceable in whole or in part, neither the validity
of the remaining part of such provision nor the validity of any other
provision of this Agreement shall in any way be affected thereby. In lieu of
such invalid, illegal or unenforceable provision, there shall be added
automatically as part of this Agreement a provision as similar in terms to such
invalid, illegal or unenforceable provision as may be possible and be valid,
legal and enforceable.

     9.   This Agreement shall be governed by Texas law.

          the "Agreements")

Dear Mike:

The Company is currently engaged in discussions with General Electric Company
("GE") concerning a possible merger of the Company with an indirect,
wholly-owned subsidiary of GE. As part of such discussions, GE has requested
that certain provisions in the Agreements be amended. This Letter Agreement is
to confirm our understanding and agreement with respect to the following
amendments, which amendments shall be effective only upon occurrence of the
effective date (the "Effective Date") of the aforementioned merger:

AMENDMENT TO BONUS AGREEMENT:

     1.   The first sentence of Paragraph 1.a. is hereby deleted in its entirety
          and the following inserted in place thereof:

              "If Executive is a full-time employee of the Company in good
          standing on the closing of a Sale of the Company (as defined in
          paragraph 3 below), then Executive will be entitled to a one-time
          bonus of $307,500, less all applicable withholdings (the "Bonus").

AMENDMENT TO OFFER AGREEMENT:

     1.   The first two sentences of the second paragraph on page 2 are hereby
          deleted and the following inserted in place thereof:

              "The Company may, at any time and for any reason, terminate
          your employment without any liability to you whatsoever except as
          expressly provided in this letter. If your employment is terminated
          by the Company for any reason other than for cause (which shall
          mean for all purposes herein



                                    A-I-67

          fraud, dishonesty or willful misconduct), the Company will pay to
          you, within 5 business days after the date of such termination, a
          lump sum payment equal to the pro rata portion of your base salary
          (as set forth in the first sentence of the second paragraph of
          this letter) (a) for the period beginning on the date of such
          termination and ending on the twenty month anniversary of the
          Effective Date if such termination occurs on or before the eight
          month anniversary of the Effective Date; or (b) for the period
          beginning on the date of such termination and ending on the first
          year anniversary of such termination if such termination occurs
          after the eight month anniversary of the Effective Date. If at any
          time following the 60th day after the Effective Date, you choose
          voluntarily to terminate your employment, the Company will pay to
          you, within 5 business days after the date of such termination, a
          lump sum payment equal to the pro rata portion of your base salary
          (as set forth in the first sentence of the second paragraph of this
          letter) for the period beginning on the date of such termination
          and ending on first year anniversary of such termination."

     3.   The first, second and third sentences of the third paragraph on page 2
          are hereby deleted and the following inserted in place thereof:

              "Furthermore, if (a) at any time after the Effective Dare and
          before the eight month anniversary of the Effective Date, the
          Company terminates your employment other than for cause or (b) if
          at any time following the 60th day after the Effective Date and
          before the eight month anniversary of the Effective Date you choose
          to voluntarily terminate your employment, the Company will pay to
          you, within 5 business days after the date of such termination, a
          lump sum payment equal to $42,000."

AMENDMENT APPLICABLE TO BOTH AGREEMENTS:

     4.   Notwithstanding anything to the contrary in the Agreements (as amended
          by this Letter Agreement), any and all payments to the Executive
          under the Agreements (as modified by this Letter Agreement), shall
          be reduced (but not below zero) so that the present value, as
          determined in accordance with Section 280G(d)(4) of the Internal
          Revenue Code of 1986, as amended (the "Code"), of such payments
          plus any other payments that must be taken into account for
          purposes of any computation relating to the Executive under Section
          280G(b)(2)(A)(ii) of the Code, shall not in the aggregate, exceed
          2.99 times the Executive's "base amount", as such term is defined
          in Section 280G(b)(3) of the Code. The Company and the Executive
          agree that the Executive's "base amount" for these purposes equals
          $251,606. Notwithstanding any other provision hereof, no
          reduction in payments under the limitation contained in the
          immediately preceding sentence shall be applied to payments
          hereunder which do not constitute "excess parachute payments"
          within the meaning of the Code. Any payments in excess of the


                                    A-I-68

<PAGE>

          limitation of this Section 4 or otherwise determined to be "excess
          parachute payments" made to the Executive hereunder shall
          constitute a loan from the Company to the Executive, resulting in
          an amount owing from the Executive to the Company with interest
          from the date of receipt by the Executive to the date of repayment
          (or offset) at the applicable federal rate under Section 1274(d) of
          the Code, compounded semi-annually, which shall be payable to the
          Company upon demand. It is the Company's intent not to make any
          payments to the Executive that constitute "excess parachute
          payments" under Section 280G of the Code, and this Section 4 shall
          be construed strictly in favor of such intent.

If the foregoing accurately sets forth the principal terms of our mutual
intentions and understandings with respect to these amendments to the
Agreements, please execute and return an copy of this Letter Agreement.

Sincerely yours,

                         ----------------------------

          This Amendment to Bonus Agreement (this "Agreement") is entered
into between InnoServ Technologies, Inc. (the "Company") and Michael G. Puls,
President and Chief Executive Officer of the Company (the "Executive").

          WHEREAS, the Executive and the Company have previously entered into
a Bonus Agreement, dated December 20, 1996, which was amended March 28, 1997
(as amended, the "Bonus Agreement"), in order to provide an incentive to the
Executive to remain in the employ of the Company while the Company is
investigating strategic alternatives in order to maximize shareholder value;

          WHEREAS, the board of directors of the Company (the "Board of
Directors") has determined that it is in the best interests of the Company
and the shareholders of the Company to amend the Bonus Agreement as
hereinafter provided in order to better achieve the purposes of the Bonus
Agreement;

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, the Company and Executive agree as follows:

          1.   Unless otherwise defined herein, terms are used as defined in
the Bonus Agreement.

          2.   Paragraph 1 of the Bonus Agreement is hereby amended to read in
its entirety as follows:

               "a.   Subject to paragraph 2 below, if Executive is a full-time
     employee of the Company in good standing on the closing of a Sale of the
     Company (as defined in paragraph 3 below), then Executive will be
     entitled to a one-time bonus of $300,000, PLUS an additional amount
     equal to (A) $100,000, multiplied by (B) a fraction, the numerator of
     which shall equal the amount by which the Sale Price of the Company
     exceeds $16 million and the denominator of which shall equal $4 million,
     less all applicable withholdings (the "Bonus"). The Bonus will be
     payable in full, in cash on the closing date of such Sale of the Company.

               b.   The Sale Price of the Company, if a stock sale, shall be
     the product of (i) the average consideration paid for a share of common
     stock of the Company and (ii) the sum of (A) the number of such shares
     acquired by the other party to the transaction (or considered
     outstanding and for which payment is made by the acquiror), plus (B) the
     number of such shares issuable upon exercise of options, warrants or
     other rights or conversion or exchange of securities all as outstanding
     on the date of this Agreement and, without duplication, as thereafter
     issued or granted. For the purpose of clause (i) of the foregoing
     sentence, all shares shall be deemed to have been acquired if more than
     50% of


                                    A-I-70

<PAGE>

     the Company's outstanding common stock is acquired by a "group" as that
     term is used in Section 13(d)(3) of the Securities Exchange Act of 1934.

               c.   For the purposes of calculating the Sale Price of the
     Company, equity securities constituting a part of the consideration
     referred to in clause (i) of paragraph 1.b. above that are traded on a
     national securities exchange or quoted on the National Association of
     Securities Dealers National Market System shall be valued at the last
     closing price thereof prior to the date of the consummation or closing
     of any such Sale of the Company.

               d.   The Sale Price of the Company, if an asset sale, shall be
     the sum of (i) the cash (or other consideration) paid by the purchaser
     for such assets and (ii) any debt assumed by the purchaser of such
     assets."

          3.   This Agreement supersedes any prior agreements or
understandings with respect to the subject matter hereof. Except as amended
hereby, the Bonus Agreement shall continue in full force and effect. This
Agreement shall inure to the benefit of, and be binding upon, the parties
hereto and their respective heirs, successors, legal representatives and
assigns.

ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS.

          5.   This Agreement may be executed in any number of counterparts,
all of which taken together shall constitute one and the same instrument.

          6.   References in the Bonus Agreement to the "Agreement" shall

                                   BONUS AGREEMENT


     This Bonus Agreement (this "Agreement") is entered into between InnoServ
Technologies, Inc. (the "Company") and Michael G. Puls, President and Chief
Executive Officer of the Company (the "Executive").

                                 WITNESSETH:

     WHEREAS, the Executive is currently employed by the Company in the
capacity of President and Chief Executive Officer; and

     WHEREAS, the board of directors of the Company (the "Board of
Directors") has determined that it is in the best interests of the Company
and the shareholders of the Company that the Company from time to time
investigate strategic alternatives in order to maximize shareholder value; and

     WHEREAS, the Executive is a member of senior management of the Company
and has access to proprietary information pertaining to the business and
operations of the Company; and

     WHEREAS, the Board of Directors has determined that it is in the best
interests of the Company to provide an incentive to the Executive to remain
in the employ of the Company while the Company is investigating such
strategic alternatives;

     NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein, the Company and Executive agree as follows:

     1.  Subject to paragraph 2 below, if Executive is a full-time employee
of the Company in good standing on the closing of a Sale of the Company (as
defined in paragraph 3 below), then Executive will be entitled to a one-time
bonus of $150,000, less all applicable withholdings (the "Bonus"). The Bonus
will be payable in full, in cash on the closing date of such Sale of the
Company.

     2.  Executive will not be eligible for benefits hereunder if he resigns,
retires, becomes disabled, fails to return from a leave of absence, dies, or
is terminated for cause prior to the close of the Sale of the Company.

     3.  For purposes of this Agreement, a Sale of the Company shall be
deemed to have occurred if the Company disposes of all of its stock or
substantially all of its assets to another party, whether by way of merger,
transfer of assets or otherwise, for cash or securities, in one or a series
of transactions.

     4.  This Agreement is not and shall not be deemed an employment
agreement, and shall not give the Executive the right to be retained in the
employment of the Company.

parties hereto and their respective heirs, successors, legal representatives,
and assigns.

     6.   Neither this Agreement nor any right or interest hereunder shall be
assignable by the Executive, his beneficiaries or legal representatives.

     7.   If any provision of this Agreement shall be determined to be
invalid, illegal or unenforceable in whole or in part, neither the validity
of the remaining part of such provision nor the validity of any other
provision of this Agreement shall in any way be affected thereby. In lieu of
such invalid, illegal or unenforceable provision, there shall be added
automatically as part of this Agreement a provision as similar in terms to
such invalid, illegal or unenforceable provision as may be possible and be
valid, legal and enforceable.

     8.   This Agreement shall be governed by Texas law.

     9.   This Agreement constitutes the entire agreement of the parties with
respect to the subject matter hereof and supersedes all prior agreements,
oral and written, between the parties hereto with respect to the subject
matter hereof. This Agreement may be modified or amended only by an
instrument in writing signed by both parties hereto.

     10.  This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together constitute one
and the same instrument.

                                  AGREEMENT


     THIS AGREEMENT (the "Agreement") is made and entered into as of May ___,
1998, by and among GENERAL ELECTRIC COMPANY, a New York corporation
("Parent"), DIAMOND MERGER SUB, INC., a California corporation ("Sub") and a
wholly owned subsidiary of a wholly owned subsidiary of Parent, and INNOSERV
TECHNOLOGIES, INC., a California corporation ("Company").

                                 RECITALS

     Parent, Sub and Company are parties to that certain Agreement and Plan
of Merger, dated May ___, 1998 (the "Merger Agreement"). Unless otherwise
defined herein, capitalized terms in this Agreement shall have the meanings
ascribed to such terms in the Merger Agreement.

     Pursuant the Merger Agreement, Sub will merge with and into Company and
all of the shares of Common Stock of Company shall convert into the right to
receive the Per Share Merger Consideration.

     Pursuant to Section 9.1(b) of the Merger Agreement, a condition
precedent to the obligation of each party to the Merger Agreement to effect
the Merger is that the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act") shall have expired or been
terminated.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants set forth below, and for their mutual reliance, Parent, Sub and
Company agree as follows:

     1.   HSR Termination.

          (a)  If the Company has not been provided with a notice in writing
     from the United States Department of Justice ("DOJ") to the effect that
     the waiting period under the HSR Act with respect to the Merger has been
     terminated or has expired (the "Termination Notice") on or prior to 5:00
     p.m. central daylight time on the later of June 22, 1998 or the date of
     the meeting of the Company's shareholders at which the shareholders vote
     in favor of the Merger (the "Expiration Time"), Parent hereby agrees to
     pay upon demand by Company, via a wire transfer of immediately available
     funds, an amount equal to One Million Two Hundred Thousand Dollars
     ($1,200,000) (the "HSR Amount") to the Company, deposited in an account
     to be designated by the Company to Parent in writing.

          (b)  If, at any time after the Termination Notice has been received
     by the Company but prior the Effective Date, the DOJ initiates an action
     in federal court seeking to challenge, block, or otherwise delay the
     consummation of the Merger or notifies the Parent or Company of its
     intent to challenge, block or otherwise delay the consummation of the
     Merger, the Parent shall have a period of ten (10) days from (i) the
     initiation of such action or (ii) the receipt by Parent or Company,
     whichever is sooner, of notification of DOJ's intent to challenge, block
     or otherwise delay the consummation of the Merger, to cause, induce or
     otherwise persuade the DOJ to drop all actions against or adverse to the
     consummation of the Merger.  If on or prior to the close of business on
     such 10th day,


                                    A-I-77

<PAGE>

     the Company has not been provided with written notice by the DOJ stating
     its acquiescence to the Merger then unless the Company has already been
     paid the HSR Amount pursuant to 1(a), Parent hereby agrees to pay upon
     demand by Company, via a wire transfer of immediately available funds,
     an amount equal to the HSR Amount to the Company, deposited in an
     account to be designated by the Company to Parent in writing.

          (c)  The payments described under Section 1 of this Agreement shall
     be made irrespective of whether or not the Merger Agreement has been
     terminated for any reason.

     2.   TERMINATION.  This Agreement shall terminate upon the earlier of
(i) the Effective Date, or (ii) disbursement in full of the HSR Amount in
accordance with the terms of this Agreement.

     3.   WAIVER OF OFFSET.  In no event shall Parent or Sub have, and Parent
and Sub hereby specifically and irrevocably waive any and all rights Parent
or Sub, as the case may be, now has or may in the future have to offset any
amounts due to Parent or Sub against any amounts owed to Company as a result
of this Agreement.

     4.   REMEDIES NOT EXCLUSIVE.  No remedy herein conferred upon or
reserved to Parent, Sub or Company is intended to be exclusive of any other
remedy or remedies provided to Parent or Company herein or in the Merger
Agreement and each and every such remedy shall be cumulative and shall be in
addition to every other remedy given hereunder or under the Merger Agreement
or now or hereafter existing at law or in equity. No delay or omission of
Company in exercising any right or power granted to it hereunder shall impair
any such right or power or shall be construed to be a waiver or an
acquiescence thereto.

     5.   ATTORNEY'S FEES.  If Company is required to commence legal action
to enforce any provision of this Agreement and is successful in such action,
Company shall receive as part of any award, judgment, decision, or other
resolution of such legal action its costs and attorneys' fees as determined by
the person or body making such award, judgment, decision, or resolution.
Should any such legal action be settled before the commencement of a lawsuit,
Company shall be entitled to include as part of its alleged damages the
attorneys' fees incurred in connection with such legal action.

     6.   TIME OF ESSENCE.  Time is of the essence with respect to each of
the provisions of this Agreement.

     7.   NOTICES.  Notices required and authorized to be given hereunder
shall be in writing and shall be deemed effective upon personal delivery or
two (2) business days after deposit with a nationally recognized courier such
as Federal Express, or upon transmission by facsimile with prompt telephone
confirmation of receipt thereto to the address of the respective party
indicated below. Company, Sub and Parent may, by written notice given by each
to the other, designate any address or addresses to which notices,

                                      OF

                        INNOSERV TECHNOLOGIES, INC.

                          ---------------------

                  Pursuant to Sections 400 & 401 of the
                      General Corporation Law of the
                           State of California

                          ---------------------

     I, Michael Puls, President and Tom Hoefert, Assistant Secretary of
InnoServ Technologies, Inc., a corporation organized and existing under the
General Corporation Law of the State of California (the "Company"), in
accordance with the provisions of Section 401 thereof, HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors of
the Company (the "Board") by the Articles of Incorporation of the Company,
the Board duly adopted the following resolution designating a Series B of
Preferred Stock consisting of 700,000 shares, none of which has been issued
as of the date of this Certificate of Determination:

     RESOLVED, that pursuant to the authority vested in the Board in
accordance with the provisions of the Articles of Incorporation of the
Company, a Series B of Preferred Stock of the Company be and hereby is
created, and that the designation and number of shares of such series and the
voting powers, preferences and relative, optional and other rights of the
shares thereof, and the qualifications, limitations and restrictions thereof,
are as follows:

SERIES B PREFERRED STOCK.

1.   DESIGNATION, AMOUNT AND RANKING.

     (a)  DESIGNATION AND AMOUNT.  The shares of the series created in this
resolution shall be designated as "Series B Preferred Stock" (the "Series B
Preferred Stock") and the number of shares constituting such series shall be
Seven Hundred Thousand (700,000).

     (b)  RANKING.  With regard to rights to receive dividends, rights to
distributions of assets upon liquidation, dissolution or winding up of the
affairs of the Company, and rights to payment upon redemption, the Series B
Preferred Stock shall rank senior and prior in right to (i) the Common Stock,
par value $.01 per share, of the Company as constituted on the date of this
Certificate of Designation or as such stock may be reconstituted from time to
time after such date


                                    A-I-82

<PAGE>

(the "Common Stock"), and (ii) as to any other series of Preferred Stock, as
established by the Board.

2.   DIVIDENDS.

     (a)  ACCRUAL OF DIVIDENDS. The holders of the Series B Preferred Stock
shall have no right to receive dividends except as provided in this Section
2. Each holder of a share of Series B Preferred Stock shall be entitled to
receive, when declared by the Board, out of the funds of the Corporation
legally available therefor pursuant to the California General Corporation Law
("Legally Available Funds"), cumulative dividends in cash in the amount of
$0.32 per share per annum. Such dividends shall accrue from day to day,
beginning six (6) months from the date of issuance of such share, whether or
not earned or declared, and shall be due and payable semi-annually on the
last day of each June, and December, beginning the last day of December 1998;
provided that whenever any such payment date is a Saturday, Sunday or public
or bank holiday or the equivalent for banks generally under the laws of the
State of Texas (any other day being a "business day"), such dividends may be
paid on the next succeeding business day (the day on which such payment is to
be made a "Dividend Payment Date").  Any such dividends not paid when due
or otherwise not thereafter paid as set forth in Section 2(b) shall become
part of the Liquidation Value except with respect to such dividends with
respect to shares that are converted pursuant to Section 6, which dividends
shalt be payable pursuant to Section 6(b).

     (b)  OTHER DIVIDENDS.  Other than dividends of Common Stock on the
Common Stock, no dividend or other distribution shall be paid, or declared
and set apart for payment, on the shares of any class or series of capital
stock of the Company, unless any accrued but unpaid dividends owed to holders
or former holders Series B Preferred Stock are first paid in full pursuant to
Sections 2(a) or 6(b) and the outstanding shares of Series B Preferred Stock
are included in such dividend or distribution PARI PASSU to the shares of
capital stock of the Company to which the dividend or distribution is being
paid or declared with respect to, by applying the Conversion Ratio (as
hereinafter defined in Section 6) to such shares of Series B Preferred Stock
as if such shares had been converted immediately prior to the record date of
such dividend or distribution.

3.   LIQUIDATION.

     (a)  PREFERENCE.  In the event of any voluntary or involuntary
dissolution, liquidation or winding up of the affairs of the Company, after
payment or provision for payment of the debts and other liabilities of the
Company and payment or provision for payment of any class or series of
capital stock of the Company ranking as to assets senior to the Series B
Preferred Stock then outstanding, the holder of each share of Series B
Preferred Stock shall be entitled to receive out of the assets of the
Company, whether such assets are capital, surplus or earnings, an amount
equal to the Liquidation Value (as hereinafter defined) of such share before
any payment shall be made or assets distributed on the Common Stock or any
other class or series of capital stock of the Company ranking as to assets
junior to the Series B Preferred Stock.  After payment to the holders of
Series B Preferred Stock of the amounts to which such holders are entitled as
set forth in this Section 3(a), the holders of the Series B Preferred Stock
shall have no claim, in their capacity as holders, to any of the remaining
assets of the Company.


                                    A-I-83

<PAGE>

     (b)  PARTIAL PAYMENT.  If upon any dissolution, liquidation or winding
up of the affairs of the Company, the assets of the Company distributable
among the holders of the Series B Preferred Stock shall be insufficient to
permit the payment to them of the full preferential amounts to which they are
entitled, then the entire assets of the Company so to be distributed shall be
distributed ratably among the holders of the Series B Preferred Stock.

     (c)  REMAINING ASSETS.  After payment or distribution to the holders of
the Series B Preferred Stock of the full amounts set forth in Section 3(a),
the holders of the Common Stock and any other class or series of capital
stock of the Company ranking as to assets junior to the Series B Preferred
Stock then outstanding shall be entitled to receive in accordance with their
respective preferences and, in the absence thereof, ratably all remaining
assets of the Company to be distributed.

     (d)  REORGANIZATION.  For the purposes of this Section 3, a liquidation,
dissolution or winding up of the affairs of the Company shall not be deemed
to be occasioned by or to include any Reorganization. For the purposes of
this Agreement, a "Reorganization" shall mean any of, or any combination of,
a capital reorganization, any reclassification of the Common Stock (other
than a change in par value or as a result of a stock dividend, subdivision,
split-up or combination of shares), the consolidation or merger of the
Company with or into another person, any agreement or arrangement (including
any tender offer) that contemplates the acquisition of beneficial ownership
of more than 35% of the outstanding shares of the Company's Common Stock, or
the sale or other disposition of all or substantially all of the property and
assets of the Company to another person.

     (e)  LIQUIDATION VALUE.  The "Liquidation Value" per share of the Series
B Preferred Stock as of any particular date shall be the sum of (i) $4.00
plus (ii) all accrued but unpaid dividends as of such date.

4.   REDEMPTION.

     (a)  OPTIONAL REDEMPTION.  To the extent the Company shall have Legally
Available Funds therefor, the Company shall have the right, but not the
obligation, to redeem all, or any portion thereof, of the shares of Series B
Preferred Stock outstanding at any time after the date of the issuance
thereof at a redemption price per share equal to the Liquidation Value
thereof at such date; provided, that the holder of such shares shall have the
right, at such holder's option, to exercise such holder's conversion rights
granted under Section 6 hereof, if applicable, prior to the applicable
redemption date.

     (b)  REORGANIZATION REDEMPTION.  The Company shall notify each of the
holders of Series B Preferred Stock as soon as practicable after, but in no
event later than ten (10) days after the consummation of a Reorganization.
Within twenty (20) days of such notice from the Company, each of the holders
of Series B Preferred Stock shall, at any such holder's option, have the
right to cause the Company to redeem all, and not less than all, of the
outstanding Series B Preferred Stock held by such holder at a price per share
equal to the Liquidation Value thereof.


                                    A-I-84

<PAGE>

     (c)  MANDATORY REDEMPTION.  On May 19, 2008 (or if not a business day on
the next business day after May 19, 2008), the Company shall redeem, to the
extent the Company shall have Legally Available Funds therefor, all shares of
Series B Preferred Stock then outstanding at the close of business upon such
date at a redemption price per share equal to the Liquidation Value thereof
at such date.

     (d)  PAYMENT OF REDEMPTION PRICE.  For each share of Series B Preferred
Stock which is to be redeemed, the Company shall be obligated, on the
applicable redemption date to pay to the holder thereof (upon surrender by
such holder at the Company's office of the certificate representing such
share) the applicable redemption price thereof. If the Company lacks Legally
Available Funds for redemption of shares of Series B Preferred Stock on any
such redemption date required to redeem the total number of shares to be
redeemed on such date, the maximum possible number of shares shall be
redeemed to the extent of Legally Available Funds ratably among the holders
of the shares to be redeemed based upon the aggregate applicable redemption
price of such shares held by each such holder. At any time thereafter if
Legally Available Funds become available for the redemption of shares of
Series B Preferred Stock, such funds will immediately be used to redeem the
balance of the shares which the Company has become obligated to redeem on any
such redemption date but which it has not redeemed.

     (e)  NOTICE OF REDEMPTION; REDEMPTION DATE.

          (i)    In the case of a redemption pursuant to Section 4(a), the
     Company shall provide written notice of each redemption of Series B
     Preferred Stock to each record holder thereof not less than five (5)
     business days prior to the applicable redemption date, stating the date
     and place of redemption, the applicable redemption price and the number of
     shares held by such holder to be redeemed.

          (ii)   In the case of a redemption pursuant to Section 4(b), the
     Company shall cause the redemption date to occur not more than five (5)
     business days after notice of a demand for redemption is received by the
     Company from the holder.

          (iii)  In the case of a redemption pursuant to Section 4(c), the
     Company shall provide written notice of each redemption of Series B
     Preferred Stock to each record holder thereof not more than sixty (60)
     nor less than thirty (30) days prior to the applicable redemption date,
     stating the date and place of redemption, the applicable redemption price
     and the number of shares held by such holder to be redeemed.

     (f)  EFFECT OF REDEMPTION.  If notice of redemption shall have been
given by the Company as provided in Section 4(d), and if on or before such
redemption date the aggregate redemption price of the shares to be redeemed
which shall not have theretofore been converted as provided in Section 6
shall have been set aside by the Company in a separate account so as to be
available for the redemption of such shares, then such shares, whether or not
the certificates therefor shall have been surrendered for redemption, shall
be deemed no longer outstanding for any purpose and all rights of the holders
with respect to such shares shall thereupon cease and terminate, except only
if not so converted, the right to receive out of the funds so set aside such


                                    A-I-85

<PAGE>

redemption price, without interest, upon endorsement, if required, and
surrender by the holders of their certificates for such shares.

5.   VOTING RIGHTS.  Except as otherwise expressly provided by law, shares of
Series B Preferred Stock shall not have any right to vote for the election of
directors or for any other purpose, and said shares shall not be entitled to
any notice of any meeting of stockholders of the Company.

6.   CONVERSION.  The rights of the holders of shares of Series B Preferred
Stock to convert such shares into shares of Common Stock and the terms and
conditions of such conversion shall be as follows:

     (a)  RIGHT TO CONVERT.  Each share of Series B Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the
earlier of (i) payment of all amounts due to the Company pursuant to that
certain agreement referenced in Section 8.10 of the Agreement and Plan of
Merger, dated May 19, 1998, ("the Merger Agreement") by and among General
Electric Company, Diamond Merger Sub, Inc., and the Company, or (ii) the
later of (A) September 30, 1998 or (B) termination of the Merger Agreement,
and prior to the applicable redemption date therefor (unless the Company
shall fail to pay or provide for the payment of the applicable redemption
price in respect thereof), at the office of the Company or any transfer agent
for the Series B Preferred Stock or the Common StocK into the number of the
fully paid and nonassessable shares of Common Stock determined in accordance
with Section 6.  In order to convert shares of the Series B Preferred Stock
into shares of Common Stock the holder thereof shall surrender the
certificate or certificates therefor, duly endorsed, at the office of the
Company or to the transfer agent for the Series B Preferred Stock or the
Common Stock, together with written notice to the Company stating that such
holder elects to convert the same and setting forth the name or names in
which such holder wishes the certificate or certificates for Common Stock to
be issued, and the number of shares of Series B Preferred Stock being
converted.

          (b)  CONVERSION MECHANICS.  The Company shall, as soon as
     practicable after the surrender of the certificate or certificates
     evidencing shares of Series B Preferred Stock for conversion at the
     office of the Company or the transfer agent for the Series B Preferred
     Stock or the Common Stock, issue to each holder of such shares, or such
     holder's nominee or nominees, a certificate or certificates evidencing
     the number of shares of Common Stock (and any other securities and
     property) to which such holder shall be entitled and, in the event that
     only a part of the shares evidenced by such certificate or certificates
     is converted, a certificate evidencing the number of shares of Series B
     Preferred Stock which are not converted.  A conversion shall be deemed
     to have been effective immediately prior to the close of business on the
     date the holder surrenders its shares of Series B Preferred Stock to be
     converted, so that, with respect to such conversion, except with respect
     to the rights set forth in the last sentence of this Section 6(b), the
     rights of the holder of such shares of Series B Preferred Stock as such
     shall cease at the effective time of such conversion and the person or
     persons entitled to receive the shares of Common Stock issuable upon
     such conversion shall be treated for all purposes as the record holder
     or holders of such shares of Common Stock at such time. If the last day
     for the exercise of the right of conversion shall not be a business day
     such conversion


                                    A-I-86

<PAGE>

     right may be exercised on the next succeeding business day.  Upon any
     conversion of Series B Preferred Stock, to the extent there are any
     accrued but unpaid dividends due and owing the holders of such Series B
     Preferred Stock so converting, the Company shall, within one (1) year
     from the date of such conversion, pay to such converting holders the
     full amount of such accrued but unpaid dividends, with interest
     accumulating at the rate of eight percent (8%) per annum, from the date
     of such conversion; and provided that the restrictions set forth in
     Section 2(b) shall survive until such declaration and payment.

     (c)  CONVERSION RATIO.  Subject to Sections 6(d) and 6(e), each share of
Series B Preferred Stock shall be convertible into one (1) share of Common Stock
(the "Conversion Ratio").

     (d)  ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS.  If outstanding
shares of the Common Stock shall be subdivided into a greater number of
shares, or a dividend in Common Stock or other securities of the Company
convertible into or exchangeable for Common Stock (in which latter event the
number of shares of Common Stock issuable upon the conversion or exchange of
such securities shall be deemed to have been distributed), shall be paid in
respect to the Common Stock, the Conversion Ratio in effect immediately prior
to such subdivision or at the record date of such dividend shall,
simultaneously with the effectiveness of such subdivision or immediately
after the record date of such dividend, be proportionately increased, and
conversely, if outstanding shares of the Common Stock shall be combined into
a smaller number of shares, the Conversion Price in effect immediately prior
to such combination shall simultaneously with the effectiveness of such
combination, be proportionately reduced.

     (e)  REORGANIZATION.  In the event that the Company shall propose or be
subject to a Reorganization, the Company shall give five (5) business days
written notice to holders of Series B Preferred Stock prior to such
Reorganization. In the event of a Reorganization, the holders of the Series B
Preferred Stock shall thereafter be entitled to receive upon conversion of
the Series B Preferred Stock the kind and number of shares of Common Stock or
other securities or property including cash) of the Company, or other
corporation resulting from such consolidation or surviving such merger or to
which such property and assets shall have been sold or otherwise disposed of
to which a holder of the number of shares of the Common Stock into which the
Series B Preferred Stock was convertible immediately prior to such
Reorganization would have been entitled to receive (together with any accrued
but unpaid dividends owed to holders of Series B Preferred Stock pursuant to
Section 2(a), as payable pursuant to Section 6(b)); and in any such case
appropriate adjustment shall be made by the Board in the application of the
provisions herein set forth with respect to the rights and interests
thereafter of the holders of the Series B Preferred Stock, to the end that
the provisions set forth herein (including the specified changes and other
adjustments to the Conversion Ratio) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any shares, other securities or
property thereafter receivable upon conversion of the Series B Preferred
Stock.  The provisions of this Section 6(e) shall similarly apply to
successive Reorganizations.

     (f)  CERTIFICATE OF ADJUSTMENT.  In each case of an adjustment or
readjustment of the Conversion Ratio or the number of shares of Common Stock
or other securities or property deliverable upon conversion of the Series B
Preferred Stock, the Company shall compute such


                                    A-I-87

<PAGE>

adjustment or readjustment in accordance with this Section 6, prepare a
certificate showing such adjustment or readjustment and mail such certificate
to each registered holder of Series B Preferred Stock at the holder's address
as shown on the books of the Company. The certificate shall set forth such
adjustment or readjustment, showing the facts upon which such adjustment or
readjustment is based, including a statement of (i) the Conversion Ratio at
the time in effect and (ii) the type and amount, if any, of other securities
or property which at the time would be received upon conversion of the Series B
Preferred Stock. Such notice may be given in advance of such adjustment or
readjustment and may be included as part of a notice required to be given
pursuant to Section 6(g).

     (g)  NOTICES OF RECORD DATE.  In the event the Company shall propose to
take any action of the type or types requiring an adjustment to the
Conversion Ratio or the number, kind or class of shares or other securities
or property into which the Series B Preferred Stock shall be convertible
pursuant to this Section 6, the Company shall give five (5) business days
prior written notice to the holders of the Series B Preferred Stock in the
manner set forth in Section 6(f), which notice shall specify the record date,
if any, with respect to any such action and the date on which such action is
to take place. Such notice shall also set forth such facts with respect
thereto as shall be reasonably necessary to indicate the effect of such
action (to the extent such effect may be known at the date of such notice) on
the Conversion Ratio and the number, kind or class of shares or other
securities or property which shall be deliverable upon the occurrence of such
action or deliverable upon the conversion of the Series B Preferred Stock.
The omission or delay in giving such notice shall not affect the validity or
effectiveness of such action.

     (h)  RESERVATION OF STOCK ISSUABLE UPON CONVERSION.  The Company shall
at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of Series B Preferred Stock, such number of its shares of Common
Stock as shall from time to time be sufficient to effect a conversion of all
outstanding shares of the Series B Preferred Stock, and if at any time the
number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding shares of the
Series B Preferred Stock, the Company shall promptly seek such corporate
action as may, in the opinion of its counsel, be necessary to increase its
authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purpose.

     (i)  PAYMENT OF TAXES.  The Company shall pay all taxes and other
governmental charges (other than any income or other taxes imposed upon the
profits realized by the recipient) that may be imposed in respect of the
issue or delivery of shares of Common Stock or other securities or property
upon conversion of shares of Series B Preferred Stock; provided, however,
that the Company shall not be required to pay any tax or other governmental
charge which may be payable in respect of any transfer involved in the issue
or delivery of any certificate in a name other than that of the holder of the
Series B Preferred Stock converted, and the Company shall not be required to
issue or deliver such certificate unless and until the person or persons
requesting the issuance thereof shall have paid to the Company the amount of
such tax or other governmental charge or shall have established to the
satisfaction of the Company that such tax or other governmental charge has
been paid.


                                    A-I-88

<PAGE>

     (j)  SURRENDERED SHARES.  All certificates representing Series B
Preferred Stock surrendered for conversion or redeemed shall be appropriately
canceled on the books of the Company, and the shares so converted represented
by such certificates shall be restored to the status of authorized but
unissued shares of Preferred Stock of the Company.

          We also examined such agreements, certificates, and other documents

          B.   COMMENTS, ASSUMPTIONS, LIMITATIONS, QUALIFICATIONS, AND
EXCEPTIONS.  The opinions expressed in Section C below are based upon, and
subject to, the following comments, assumptions, limitations, qualifications,
and exceptions:

          1.   We have assumed (a) the genuineness of all signatures, other
     than the signatures of the officers of the Acquired Company acting in
     such capacity, (b) the authenticity of all documents submitted to us as
     originals, (c) the conformity to original documents of all documents
     submitted to us as conformed, certified, or photostatic copies thereof,
     and (d) the authenticity and completeness of the originals of such

     than the Acquired Company has (a) adequate legal capacity, power, and
     authority to execute, deliver, and perform the Merger Agreement and each
     document ancillary thereto to which it is a party, and (b) taken all
     corporate or other action necessary to duly execute and deliver, and has
     duly executed and delivered, the Merger Agreement and each such other

          3.   With respect to questions of fact, we have relied exclusively
     upon (a) certificates and assurances of public officials, and (b)
     certificates and assurances of officers of the Acquired Company, without
     having independently verified the accuracy or completeness thereof.

          4.   We are unaware of any agreements or understandings among the
     parties to the Merger Agreement that would modify the terms thereof or
     the respective rights and obligations of the parties thereunder.
     Accordingly, we have assumed that no such agreement or understanding
     exists.

          5.   We express no opinion as to matters involving the laws of any
     jurisdiction other than the States of Texas and California. This opinion
     is limited to the effect of the present state of the laws of the States
     of Texas and California.

     C.   OPINIONS.  Based upon and subject to the foregoing, we are of the
opinion that:

          1.   The Acquired Company is validly existing and in good standing
     under the laws of the State of California and has corporate power and
     authority to own, lease and operate its properties and to conduct the
     business in which it is engaged as described in the Proxy Statement, to
     execute and deliver the Merger Agreement and the other agreements and
     instruments contemplated thereby to be executed by the Acquired Company,
     to consummate the transactions contemplated thereby and to perform its
     obligations under the Merger Agreement and such other agreements and
     instruments.

          2. The authorized capital stock of the Acquired Company consists of
     10,000,000 shares of Company Common Stock, $.01 par value and 5,000,000
     shares of preferred stock, $.01 par value ("Company Preferred Stock").
     All of the 3,009,395 shares of Company Common Stock and all __________
     shares of Company Preferred Stock outstanding as of May ___,1998 are
     duly and validly authorized and issued, fully paid and nonassessable and
     have not been issued in violation of any preemptive right of
     shareholders;

          3. Each Company Subsidiary is a corporation validly existing and in
     good standing under laws of the state of its incorporation. All of the
     issued and outstanding shares of capital stock of each Company
     Subsidiary is owned of record by the Acquired Company.


                                    A-I-93

<PAGE>

          4.   The Merger Agreement has been duly authorized, executed and
     delivered by the Acquired Company constitutes the legal, valid and
     binding obligation of the Acquired Company enforceable against the
     Acquired Company in accordance with its terms, except to the extent
     enforceability may be limited by bankruptcy, insolvency, reorganization,
     moratorium or other similar laws of general applicability relating to or
     affecting the enforcement of creditors' rights and by the effect of
     general principles of equity (regardless of whether enforceability is
     considered in a proceeding in equity or at law).

          5.   The execution, delivery and performance by the Acquired
     Company of the Merger Agreement do not and will not result in any breach
     of, constitute a default under or result in the creation of any lien or
     encumbrance in respect of any property of the Acquired Company or any
     Company Subsidiary pursuant to its Articles or Certificate of
     Incorporation, as amended, or By-laws or any agreement, instrument,
     judgment, decree, order, statute (including the California General
     Corporation Law), rule or regulation known to us, after due inquiry,
     which is applicable to the Acquired Company, any Company Subsidiary or
     any of their respective properties.

                                FAIRNESS OPINION
 
                                  [LETTERHEAD]
 
                                  May 11, 1998
 
The Board of Directors
Innoserv Technologies, Inc.
320 Westway, Suite 530
Arlington, TX 76018
 
Dear Sirs:
 
We understand that Innoserv Technologies, Inc. ("Innoserv" or the "Company") is
considering a transaction whereby General Electric Company, a New York
corporation acting on behalf of its GE Medical Systems business ("Parent"),
Diamond Merger Sub, Inc., a California corporation and a wholly owned subsidiary
of a wholly owned subsidiary of Parent ("SUB") will be merged with and into the
Company (the "Merger"). Pursuant to the terms of a draft Agreement and Plan of
Merger dated May 11, 1998 (the "Purchase Agreement") each issued and outstanding
share of capital stock of Innoserv, par value $0.01 per share, ("Innoserv
Shares"), including all issued and outstanding options, warrants or other stock
issuance agreements, shall be converted into the right to receive, in cash, an
amount equal to (A) the remainder of (I) $16,000,000 minus (II) (a) the MEDIQ
Payment and (b) the Escrow Payment (as defined in the draft Purchase Agreement),
divided by (B) the number of shares outstanding as of the Effective Date,
without interest thereon (the "Consideration"). The terms and conditions of the
Transaction are more fully set forth in the draft Purchase Agreement.
 
You have requested our opinion as to whether, as of the date hereof, the
Consideration to be received in the Merger is fair, from a financial point of
view, to the stockholders of Innoserv Shares.
 
SBC Warburg Dillon Read Inc. ("SBCWDR") and its predecessors have acted as
financial advisor to the Board of Directors of the Company in connection with
the Merger and will receive a fee upon the consummation thereof. In the past,
SBCWDR and its predecessors have provided investment banking services to the
Company and received reimbursement of expenses incurred in the rendering of such
services. In the ordinary course of business, SBCWDR, its successors and
affiliates may have traded securities of the Company and General Electric Inc.
for their own accounts and, accordingly, may at any time hold a long or short
position in such securities.
 
Our opinion does not address the Company's underlying business decision to
affect the Merger or constitute a recommendation to any shareholder of the
Company as to how such shareholder should vote with respect to the Merger.
 
At your direction, we have not been asked to, nor do we, offer any opinion as to
the material terms of the Purchase Agreement or the form of the Merger. In
rendering this opinion, we have assumed, with your consent, that SUB and the
Company will comply with all the material terms of the Purchase Agreement.
 
In arriving at our opinion we have, among other things, (i) reviewed certain
publicly available business, stock market, historical budget data, and
historical financial information relating to the Company, (ii) reviewed certain
internal financial information, historical budget data, and other data relating
to the business prospects of the Company, that were provided to us by the
Company and not publicly available, (iii) conducted discussions with members of
the senior management of the Company, (iv) reviewed
 
                                     A-II-1
<PAGE>
publicly available financial and stock market data with respect to certain other
companies in lines of business we believe to be generally comparable to those of
the Company, (v) compared the financial terms of the Merger with the publicly
available financial terms of certain other transactions which we believe to be
generally relevant, (vi) reviewed drafts of the Purchase Agreement, and (vii)
conducted such other financial studies, analyses, and investigations, and
considered such other information as we deemed necessary or appropriate.
 
In connection with our review, at your direction, we have not independently
verified any of the foregoing information and have, at your direction, relied on
its being complete and accurate in all material respects. We have not made an
independent evaluation or appraisal of any assets or liabilities (contingent or
otherwise) of Innoserv or any of its respective subsidiaries, nor have we been
furnished with any such evaluation or appraisal. With respect to the certain
internal financial information, historical budget data, and other data relating
to the business prospects of the Company, that were provided to us by the
Company and not publicly available, we have assumed, with your permission, that
all such information was reasonably prepared on bases reflecting the best
currently available estimates and judgments of management of Innoserv and was
based upon the historical performance of Innoserv and certain estimates and
assumptions which were reasonable at the time made. Our opinion is based on
economic, monetary, market and other conditions existing on the date hereof.
 
In rendering this opinion, we are not making any recommendation regarding
whether or not it is advisable for Shareholders to vote in favor of the Merger.
 
Based upon and subject to the foregoing, we are of the opinion, as of the date
hereof, that the Consideration to be received in the merger is fair, from a
financial point of view, to the stockholders of Innoserv Shares.
 
                                          Very truly yours,
 
                                          /s/ SBC WARBURG DILLON READ INC.
 
                                          SBC WARBURG DILLON READ INC.

                                  APPENDIX III
                            STOCK PURCHASE AGREEMENT
 
    This STOCK PURCHASE AGREEMENT, dated as of November 13, 1997 (the
"Agreement"), among MEDIQ Incorporated, a Delaware corporation ("MEDIQ"), MEDIQ
Investment Services, Inc., a Delaware corporation ("MIS" and together with
MEDIQ, collectively the "Seller"), and InnoServ Technologies, Inc., a California
corporation (the "Company").
 
                                  WITNESSETH:
 
    WHEREAS, Seller owns 2,026,438 shares (the "Issuer Shares") of the common
stock of the Company (the "Common Stock") and warrants to purchase 325,000
shares of Common Stock (the "Warrants"); and
 
    WHEREAS, the Seller and the Company had previously entered into an agreement
pursuant to which Seller would be required to distribute the Issuer Shares to
its stockholders upon demand by the Company; and
 
    WHEREAS, by letter dated September 26, 1997 (the "Distribution Request"),
the Company has requested that Seller distribute the Issuer Shares to its
stockholders, such distribution to be completed no later than 60 days from the
date of such letter; and
 
    WHEREAS, the Seller requested that the Company consider alternative
arrangements with respect to the Issuer Shares, and the respective Boards of
Directors of the Company and the Seller have considered such alternative
arrangements; and
 
    WHEREAS the Seller and the Company desire that in lieu of distribution that
Seller will sell and transfer such shares to Company in accordance with the
terms and conditions hereof; and
 
    NOW, THEREFORE, in consideration of the mutual premises and agreements set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by the parties, the parties hereto
agree as follows:
 
1.  SALE OF THE SHARES
 
    1.1  SALE.  Simultaneously with the execution and delivery hereof, the
Seller shall transfer, assign, sell and deliver to the Company, and the Company
shall purchase from the Seller all of the Issuer Shares and Warrants in
consideration of the agreements and waivers of the parties contained herein (the
"Purchase Price"). The closing (the "Closing") of the sale and purchase and
delivery of all of the Issuer Shares and Warrants shall be held on the date
hereof. At the Closing Seller shall deliver the certificates for the Issuer
Shares and the Warrants duly endorsed or accompanied by stock powers or other
appropriate instruments of transfer duly executed in blank.
 
    1.2  CHANGE IN CONTROL.
 
        (a) Before April 1, 1998, the Company shall not enter into or consummate
    a change in control (as defined below) unless the other party or parties
    thereto agree, as a condition precedent to such transaction, to pay Seller
    the amount (subject to the last sentence of this paragraph) that would have
    been received by the Seller in connection with the change of control
    transaction if all of the Issuer Shares were outstanding and held by the
    Seller at the effective time of such change in control transaction. From and
    after April 1, 1998 and through September 30, 1998, the Company shall not
    enter into or consummate a change of control unless the other party or
    parties thereto agree, as a condition precedent to such transaction, to pay
    Seller 50% of the amount (subject to the last sentence of this paragraph)
    that would have been received by the Seller in connection with the change of
    control transaction if all of the Issuer Shares were outstanding and held by
    the Seller at the effective time of such change in control transaction. Any
    amounts owed to Seller pursuant to this Section 1.3
 
                                    A-III-1
<PAGE>
    shall be paid simultaneously with the payment to the Company's shareholders
    in connection with the consummation of any transaction that constitutes a
    change in control of the Company. The Company shall not enter into any
    change in control transaction or cooperate with any third party with respect
    to a possible change in control transaction unless the other party (or
    parties) thereto agree to make adequate provision for the payment to Seller
    of all amounts provided herein. If the Company's shareholders are entitled
    to receive Marketable Consideration (as defined below) and other
    consideration in respect of a share of Common Stock, the amount that is due
    to Seller shall be determined only with respect to the portion that is
    Marketable Consideration.
 
        (b) For purposes of this Agreement, the parties intend that a "change in
    control" means a transaction or series of transactions in which the holders
    of a majority of the outstanding Common Stock receive (or have the right to
    receive) Marketable Consideration, in respect of their shares of Common
    Stock (whether by merger, sale, tender, dissolution or otherwise). For the
    purposes of this Agreement, Marketable Consideration means cash, debt or
    publicly traded equity securities of a company that had been a public
    company before such transaction (including preferred stock or any right to
    acquire such publicly traded equity security) ("Marketable Consideration").
    By way of illustration, a change in control shall include: (i) the
    consolidation or merger of the Company pursuant to which the outstanding
    shares of Common Stock are converted into the right to receive Marketable
    Consideration or (ii) the sale of all or substantially all of the assets of
    the Company for Marketable Consideration or (iii) any other transaction
    involving an exchange or sale of 50% or more of the outstanding Common
    Stock, including a tender offer, for Marketable Consideration, but excluding
    all other transactions, including where the holders of the outstanding
    Common Stock receive only securities of the Company or of another entity of
    which the Company's assets or business constitute a substantial portion, or
    reincorporation of the Company in a jurisdiction other than California.
 
        (c) For purposes of determining the amount which Seller would have
    received with respect to the Issuer Shares following a change in control,
    (1) in any transaction involving a sale or exchange of any shares of Common
    Stock, it shall be presumed that all of the Issuer Shares were sold at the
    highest average price paid to any affiliate of the Issuer for any shares in
    such transaction, (2) in any transaction involving a merger or consolidation
    of the Company, it shall be presumed that the Seller (as a shareholder)
    voted in favor of such transaction, (3) in any transaction involving the
    sale of all or substantially all of the assets of the Company, it shall be
    presumed that the Company was dissolved and its net assets distributed to
    its shareholders immediately after such transaction and (4) in any other
    change in control transaction in which a majority of the Company's
    shareholders which are not affiliates of the Company receive any
    consideration in respect of their shares of Common Stock, the Seller shall
    be presumed to have the right to receive an equivalent amount. Furthermore,
    in the event of a tender or exchange offer for less than all of the
    outstanding Common Stock, the Seller shall be treated as if it had tendered
    (which tender had been accepted) a percentage of the Issuer Shares equal to
    the highest percentage of shares of Common Stock owned by any shareholder of
    the Company which are accepted by the party making such offer; and in
    addition the Seller shall be entitled to receive an equivalent amount of any
    securities of the Company retained by such shareholder.
 
        (d) The Seller acknowledges that neither the Company nor any of its
    affiliates (i) has any fiduciary duty to Seller, any of Seller's affiliates
    or any of Seller's stockholders (the "Seller Group") by reason of this
    Agreement, (ii) is under any duty or obligation to the Seller Group to
    initiate, investigate, consider, respond or otherwise take any action with
    respect to a proposal that may result in a change of control by reason of
    this Agreement, any such potential transaction as with respect to the Seller
    Group being within the sole discretion of the Company, and (iii) any such
    potential transaction will be considered by the Company in light of the
    duties owed to the holders of the Common Stock outstanding at such time.
    Notwithstanding the above, if any third party approaches the Company or any
    of its affiliates or representatives regarding a possible change in control,
    the
 
                                    A-III-2
<PAGE>
    Company shall in good faith not delay or defer such consideration,
    evaluation or negotiation with the intent to reduce any amounts payable to
    Seller hereunder.
 
        (e) Subject to the last sentence of Section 1.2(a), any payment due to
    Seller under this Section 1.2 shall, unless Seller otherwise agrees, be paid
    in cash or in property of the kind and in the same proportion received by
    the shareholders of the Company in connection with the change in control
    transaction.

upon or otherwise in respect of any inaccuracy in or breach of (i) any
representation or warranty of Seller made in or pursuant to this Agreement or
any agreement or document required to be delivered pursuant to this Agreement,
(ii) or any breach or nonfulfillment of any covenant or obligation of Seller
contained in this Agreement or such other agreements and documents, or (iii) any
action, suit, proceeding or claim by a stockholder of the Seller (in such
capacity) challenging the transactions contemplated by this Agreement.
 
    4.2  INDEMNIFICATION BY THE COMPANY.  The Company shall indemnify and hold
Seller and its officers, directors and shareholders harmless from and against

        (b) The election by the indemnifying party, pursuant to Section 4.3(a),

    against which such claim has been made also from participating or continuing
    to participate in such defense, so long as such party bears its own legal
    fees and expenses for so doing.

                         REGISTRATION RIGHTS AGREEMENT
 
    This Registration Rights Agreement (this "Agreement") is entered into as of
the 4th day of June, 1998, between National Medical Diagnostics, Inc., a
Delaware corporation (the "Investor"), and InnoServ Technologies. Inc., a
California corporation (the "Company").
 
                            PRELIMINARY STATEMENTS:
 
    WHEREAS, General Electric Company ("GE"), Diamond Merger Sub, Inc., and the
Company are parties to an agreement and plan of merger dated as of May 19, 1998
(the "Merger Agreement").
 
    WHEREAS, the Merger Agreement provides that GE (or its designee) shall
purchase for $2,800,000, and the Company shall deliver to GE (or its designee),
700,000 shares of a newly created Series B Preferred Stock, par value $.01 per

State of California.
 
    WHEREAS, such designation has been so approved, GE has designated the
Investor as the person to purchase such Series B, the Investor has purchased
such Series B and the Company has delivered to the Investor such Series B.
 
    WHEREAS, the Merger Agreement provides that the Company and GE (or its
designee) will enter into a registration rights agreement in which the Company
will grant certain registration rights to GE (or its designee).
 
                             TERMS AND CONDITIONS:
 
    NOW THEREFORE, the Investor and the Company agree as follows:
 
                                   ARTICLE I
                              REGISTRATION RIGHTS
 
    1.1  PIGGYBACK REGISTRATION RIGHTS.
 
    (a) RIGHT TO PIGGYBACK.  Subject to the limitations set forth in Section
1.1(e) hereof, whenever the Company proposes to file a registration statement (a
"Proposed Registration") under the Securities Act of 1933, as amended (the
"Securities Act"), with respect to any equity security (as defined in the
Securities Act) (other than a registration statement on Form S-4, Form S-8 or
any successor form for the registration of securities to be offered in a
transaction subject to Rule 145 under the Securities Act or to employees of,
and/or consultants and advisors to, the Company and/or its subsidiaries pursuant
to any "employee benefit plan," as such term is defined in Rule 405 promulgated
under the Securities Act) and the registration form to be used may be used for
the registration (the "Piggyback Registration") of Piggyback Registrable
Securities, the Company will give written notice (the "Piggyback Notice") to the
Investor as soon as practicable (but in no event less than 45 days) before the
initial filing with the SEC of such registration statement, which notice shall
(i) specify the kind and number of securities proposed to be registered and the
proposed offering price or prices and distribution arrangements; (ii) include
such other information that at the time and under the circumstances would be
appropriate to include in such notice; and (iii) subject to the provisions of
Section 1.1(e), offer the Investor the opportunity to include in such filing all
Piggyback Registrable Securities which the Investor may request in accordance
with subsection 1.1(b) below. "Piggyback Registrable Securities" shall mean any
shares of common stock of the Company, par value $.01 (the "Common Stock"),
receivable by Investor as a result of the conversion and anti-dilution rights
pertaining to the Series B.
 
    (b) REQUESTS TO PIGGYBACK.  The Investor shall advise the Company in writing
(a "Piggyback Registration Request") within 15 days after the date of receipt of
the Piggyback Notice of the number or amount of each class or series of
Piggyback Registrable Securities which the investor desires to have registered.
 
                                     A-IV-2
<PAGE>
    (c) SELECTION OF UNDERWRITERS.  If the Piggyback Registration is an
underwritten offering, the Board of Directors of the Company will select a
managing underwriter or underwriters to administer the offering, who shall be
reasonably satisfactory to the Investor.
 
    (d) PIGGYBACK EXPENSES.  Subject to the limitations set forth in Section
1.3(d) hereof, all Registration Expenses (as defined in Section 1.3(d)) of the
Piggyback Registration will be paid by the Investor.
 
    (e) LIMITATIONS ON PIGGYBACK RIGHTS.  The Investor will be entitled to an
unlimited number of Piggyback Registrations. The exercise of a Piggyback
Registration shall not affect the Investor's Demand Registration rights under
Section 1.2 hereof. The Investor shall not be permitted to exercise its
Piggyback Registration rights with regard to any underwritten Piggyback
Registration where a first or second tier underwriter, or underwriters, provides
the Investor with an opinion that the amount or kind of the Investor's shares to
be included in such offering would adversely affect the success of the
securities proposed to be distributed for the account of the Company in such
offering. However, the Investor shall be entitled to include all of its
Piggyback Registrable Securities in any such Piggyback Registration before any
other securities which are entitled to be registered pursuant to the exercise of
contractual rights comparable to the rights granted in this Section 1.1.
 
    1.2  DEMAND REGISTRATION RIGHTS.
 
    (a) REQUESTS FOR REGISTRATION.  Subject to the limitations set forth in
Section 1.2(d), at any time after the Investor has the right to convert the
Series B to Common Stock pursuant to the Series B designation, the Investor may
request the Company to register under the Securities Act all or part of its
Demand Registrable Securities on Form S-1, Form S-3 or any other registration
form available for use by the Company (a "Demand Registration"). The request for
a Demand Registration (the "Demand Notice") shall specify the number of Demand
Registrable Securities requested to be registered and the anticipated per share
price range for such offering. However. the Company may postpone, for a
reasonable period of time not to exceed 90 days (but in any event not to extend
beyond the date of public disclosure of the information, or the date of
abandonment or termination of the transactions or negotiations, hereinafter
referred to), the filing of a registration statement otherwise required to be
prepared and filed by it pursuant to this subsection 1.2(a) if (i) at the time
the Company receives a Demand Notice, the Board of Directors of the Company
determines, in good faith and in its reasonable business judgment, that (A) such
Demand Registration would require the public disclosure of material non-public
information concerning any pending or ongoing material transaction or
negotiations involving the Company which, in the opinion of the Company's
outside legal counsel, is not yet required to be publicly disclosed, and (B)
such disclosure would materially interfere with such transaction or negotiations
or have a material adverse effect on the Company, and (ii) the Company
diligently and in good faith continues to pursue such transaction or
negotiations throughout the period of such postponement. The Company may not
postpone a Demand Registration pursuant to this Section 1.2(a) more than once in
any 12-month period.
 
    "Demand Registrable Securities" means, the Series B and any other shares of
Common Stock received by the Investor as a result of the conversion and
anti-dilution rights pertaining to the Series B.
 
    (b) SELECTION OF UNDERWRITERS.  If the Demand Registration is for or
includes an underwritten offering, the Investor shall select the managing
underwriter or underwriters to administer such offering, who shall be reasonably
satisfactory to the Company.
 
    (c) DEMAND EXPENSES.  Subject to the limitations set forth in Section 1.3(d)
hereof, the Investor shall pay for all Registration Expenses relating to the
Demand Registration.
 
    (d) LIMITATIONS ON DEMAND RIGHTS.  The Investor may only request two Demand
Registrations. However, in addition to such two Demand Registrations, the
Investor may make four other Demand Registrations that involve the use of Form
S-3 or such other equivalent "short-form" registration form then in use. A
registration will not count as one of the permitted Demand Registrations until
the registration statement relating thereto has become effective.

    1.3  PROCEDURE.  With respect to any Piggyback Registration or Demand
Registration, the Company shall use its best efforts to effect the registration
of all the Piggyback Registrable Securities or Demand Registrable Securities, as
the case may be (collectively, the "Request Securities"), which the Investor has
requested to be included therein, as quickly as practicable. In connection with
any such request, the Company shall do the following as expeditiously as
possible:
 
    (i) prepare and file with the SEC a registration statement on any form for
which the Company then qualifies and which is available for the registration of
the Request Securities;
 
    (ii) include in the registration on such form all the Request Securities and
use its reasonable efforts to cause such registration statement to become
effective; PROVIDED, HOWEVER, that at least two days before filing such
registration statement or any prospectus or any amendment or supplement thereto,
including documents to be incorporated be reference upon or after the initial
filing of such registration statement, the Company shall furnish to the Investor
copies of all such documents proposed to be filed (including documents to be
incorporated by reference therein), which documents will be subject to
reasonable review and comments of the Investor:
 
   (iii) unless the Company qualifies to use a Form S-3 registration statement
or any similar form then in effect, prepare and file with the SEC such
amendments and post-effective amendments and supplements to the registration
statement or any prospectus as may be necessary to keep the registration
statement effective for a period of not more than 180 days and comply with the
provisions of the Securities Act applicable to the Company with respect to the
disposition of all the Request Securities, covered by such registration
statement or any supplement to any such prospectus;
 
    (iv) if the Company qualifies to use a Form S-3 registration statement or
any similar form then in effect and if the Company receives a request for a
Demand Registration, prepare and file with the SEC such registration statement
to permit the offering of the Demand Registrable Securities to be made on a
continuous basis pursuant to Rule 415 (or any similar rule that may be adopted
by the SEC) under the Securities Act (a "Shelf Registration") and keep the Shelf
Registration current and continuously effective until 12 months from the
effective date of the Shelf Registration.
 
    (v) furnish to the Investor, such number of copies of such registration
statement, each amendment and supplement thereto, the prospectus included in
such registration statement and such other documents as the Investor may
reasonably request;
 
    (vi) use its best efforts to register or qualify such Request Securities
under such other securities or blue sky laws of such jurisdiction as the
Investor reasonably requests and do any and all other acts and things which may
be reasonably necessary or advisable to enable the Investor to consummate the
disposition in such jurisdiction (provided that the Company will not be required
to (i) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this subparagraph, (ii) subject itself
to taxation in any such jurisdiction or (iii) consent to general service of
process in any such jurisdiction);
 
   (vii) notify the Investor at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration statement
contains an untrue statement of material fact or omits any act necessary to make
the statements therein in light of the circumstances under which they were made,
not misleading, and, at the request of the Investor, the Company will, at the
Investor's own expense, prepare a supplement or amendment to such prospectus so
that, as thereafter delivered to subsequent purchasers of such Request
Securities, such prospectus will not contain an untrue statement of a material
fact or omit to state any fact necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading;
 
  (viii) cause all such Request Securities, to be listed on each securities
exchange or system on which similar securities issued by the Company are then
listed;
 
                                     A-IV-4

the public, any security issued by the issuer of such class or series or any
security exchangeable or exercisable for or convertible into any such class or
series of any such Request Securities or any such similar security, including a
sale pursuant to Rule 144 (or any similar rule then in force) under the
Securities Act, during, in the case of a Piggyback Registration, the 14 days
prior to, and during the 180 day period beginning on, the effective date of the
Piggyback Registration (except as part of such registration or pursuant to
registrations on Form S-4 or S-8 or any successor form to either such form) and,
in the case of any Demand Registration, the period commencing on the date of
filing the Demand Registration and ending on the 180th day following the
effective date of the Demand Registration (except as part of such Demand
Registration).
 
    (c) PUBLIC SALE BY THE COMPANY AND OTHERS.  Neither the Company nor any of
its Affiliates (other than the Investor, if deemed to be an Affiliate) will
effect any public sale or distribution of any securities of any class or series

<PAGE>
other Person that directly, or indirectly through one or more intermediaries,

fees with respect to the Request Securities, (ii) reasonable fees and
disbursements of counsel in connection with blue sky qualifications with respect

any costs and expenses to the extent that (x) such costs and expenses would have
been incurred by the Company absent such registration hereunder or (y) another
party is contractually obligated to pay such costs and expenses.
 
    1.4  INDEMNIFICATION REGARDING REGISTRATION RIGHTS.
 
    (a) INDEMNIFICATION BY THE COMPANY.  The Company shall indemnify the
Investor and, if applicable, its officers and directors and each person or
entity (a "Person") who controls the Investor (within the meaning of the
Securities Act) against all losses, claims, damages, liabilities and expenses,
including reasonable attorneys' fees and disbursements and expenses of
investigation, incurred by such party pursuant to any actual or threatened
action, suit, proceeding or investigation, or to which any of the foregoing
Persons may become subject under the Securities Act, the Securities Exchange Act
of 1934, as amended (the "Exchange Act"), or other federal or state laws,
insofar as such losses, claims, damages, liabilities and expenses arise out of
or are caused by any untrue or alleged untrue statement of material fact
contained in any registration statement, preliminary prospectus or definitive
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, except insofar as the same are
caused by or contained in any information furnished in writing to the Company by
the Investor specifically for use in the preparation thereof or by the
Investor's failure, if required, to deliver a copy of the registration statement
or prospectus or any amendments or supplements thereto after the Company has
furnished the Investor with copies of the same pursuant to Section 1.3(v).
 
    (b) INDEMNIFICATION BY THE INVESTOR.  In connection with any registration
statement in which the Investor is participating, the Investor shall indemnify
the Company, its directors and officers and each Person who controls the Company
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities and expenses, including reasonable attorneys' fees and disbursements
and expenses of investigation, incurred by such party pursuant to any actual or
threatened action, suit, proceeding or investigation, or to which any of the
foregoing Persons may become subject under the Securities Act, the Exchange Act
or other federal or state laws, insofar as such losses, claims, damages,
liabilities and expenses arise out of or are caused by any untrue or alleged
untrue statement of material fact contained in the registration statement,
preliminary prospectus or definitive prospectus or any amendment thereof or
supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading, but only to the extent that such untrue statement or omission is
contained in information furnished, in writing, by the Investor to the Company
specifically for use in the preparation of such registration statement or
prospectus. The amount of any indemnity under this Section 1.4(b) shall not
exceed the gross proceeds received by the Investor from the applicable offering.
 
                                     A-IV-6
<PAGE>
    (c) PROCEDURE.  Any Person entitled to indemnification hereunder will (i)
give prompt written notice to the indemnifying party of any claim with respect
to which it seeks indemnification, provided that the failure of any indemnified
party to give notice shall not relieve the indemnifying party of its obligations
hereunder except to the extent the indemnifying party is actually prejudiced by
such failure and (ii) unless in such indemnified party's reasonable judgment a
conflict of interest between such indemnified and indemnifying parties may exist
with respect to such claim, permit such indemnifying party to assume the defense
of such claim with counsel reasonably satisfactory to the indemnified party. If
such defense is assumed, the indemnifying party will not be subject to any
liability for any settlement made by the indemnified party without its consent
(but such consent will not be unreasonably withheld). An indemnifying party who
is not entitled to, or elects not to assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party a conflict of interest may exist
between such indemnified party and any other of such indemnified parties with
respect to such claim.
 
    (d) SURVIVAL.  The indemnification provided for under this Agreement will
remain in full force and effect regardless of any investigation made by or on
behalf of the indemnified party or any officer, director or controlling Person
of such indemnified party and will survive the transfer of securities.
 
    (e) CONTRIBUTION.  If the indemnification provided for in this Section 1.4
from the indemnifying parry is unavailable to the indemnified party, then the
indemnifying party, instead of indemnifying the indemnified party, shall
contribute to and pay the amount paid or payable by such indemnified party as a
result of the loss, claim, damage, liability or expenses (collectively, the
"Claim") giving rise to indemnification hereunder in such proportion as is
appropriate to reflect the relative fault of the indemnifying and indemnified
party in connection with the actions which gave rise to the Claim. The relative
fault of the indemnifying party and the indemnified party shall be determined by
reference to, among other things, whether the action in question has been made
by, or relates to, information supplied by such indemnifying party or
indemnified party, and the parties' relevant intent, knowledge, access to
information and opportunity to correct or prevent such action. The Company and
the Investor agree that it would not be just and equitable if contribution and
payment pursuant to this Section 1.4 were determined by pro rata allocation or
by any other allocation method which does not take into account the equitable
considerations referred to in the preceding sentence. The amount paid or payable
as a result of a Claim shall include any legal or other fees and expenses
reasonably incurred by such party in connection with such Claim. However, no
Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contributions and payment from
any Person who was not guilty of such fraudulent misrepresentation.
 
    1.5  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.  No Person may participate
in any underwritten registration hereunder unless such Person (a) agrees to sell
its securities on the basis provided in any underwriting arrangements reasonably
approved by the Persons entitled hereunder to approve such arrangements and (b)
accurately completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents customarily required
under the terms of such underwriting arrangements.
 
    1.6  RULE 144.  The Company shall file, on a timely basis, any reports
required to be filed by it under the Securities Act and the Exchange Act (and if
the Company is not required to file reports pursuant to the Exchange Act, the
Company shall, upon the request of the Investor, make publicly available the
information specified in subparagraph (c)(2) of Rule 144 of the Securities Act)
so as to enable the Investor to sell the Piggyback Registrable Securities and
Demand Registrable Securities without registration under the Securities Act
within the limitation of the exemptions provided by (a) Rule 144 under the
Securities Act, as such Rule may be amended from time to time or (b) any similar
rule adopted by the SEC.
 
    1.7  TRANSFER OF REGISTRATION RIGHTS.  Rights with respect to Piggyback
Registrable Securities and Demand Registrable Securities may be transferred by
the Investor (or any subsequent transferee pursuant
 
                                     A-IV-7
<PAGE>
to this Section 1.7) to any Person in connection with the transfer of Piggyback
Registrable Securities and Demand Registrable Securities to such Person, in all
cases, if (a) any such transferee shall have executed and delivered to the
Secretary of the Company a properly completed agreement substantially in the
form of EXHIBIT 1.7, (b) the transferor shall have delivered to the Secretary of
the Company, no later than 15 days following the date of the transfer, written
notification of such transfer setting forth the name of the transferor, name and
address of the transferee, and the number of Piggyback Registrable Securities
and Demand Registrable Securities which shall have been so transferred and (c)
the number of Piggyback Registrable Securities and Demand Registrable
Securities, as the case may be, which shall have been so transferred is equal to
or exceeds 50% of the total number of the Piggyback Registrable Securities and
Demand Registrable Securities, as the case may be.
 
    1.8  MERGERS CONSOLIDATIONS, ETC.  The Company shall not, directly or
indirectly enter into any merger, consolidation or reorganization in which the
Company shall not be the surviving corporation, unless prior to such merger,
consolidation or reorganization, the surviving corporation shall have agreed in
writing to assume the obligations of the Company under this Agreement, and for
that purpose references hereunder to "Piggyback Registrable Securities" and
"Demand Registrable Securities" shall be deemed to include the securities which
the holders of Piggyback Registrable Securities and Demand Registrable
Securities would be entitled to receive in exchange for such securities pursuant
to any such merger, consolidation or reorganization.
 
                                   ARTICLE II

of the other party, except (a) pursuant to Section 1.7 hereof and (b) that the
Investor may assign this Agreement in whole to an Affiliate of the Investor
without the necessity for securing prior written consent of the Company.
 
    2.3  SEVERABILITY.  If any court or any governmental authority or agency
declares all or any part of any Section of this Agreement to be unlawful or
invalid, such unlawfulness or invalidity shall not serve to invalidate any other
Section of this Agreement, and if only a portion of any Section is so declared
to be unlawful or invalid, such unlawfulness or invalidity shall not serve to
invalidate the balance of such Section.
 
    2.4  NOTICES.  All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given or made (and

(a) receipt, if made by personal service, (b) three business days after
dispatch, if made by reputable overnight courier service or (c) upon the
delivering party's receipt of a written confirmation of a transmission made by
telecopy to the respective parties at the following addresses (or at such other

    Re:  AGREEMENT AND PLAN OF MERGER (THE "MERGER AGREEMENT") AMONG INNOSERV
         TECHNOLOGIES, INC. ("INNOSERV"), GENERAL ELECTRIC COMPANY ("GENERAL
         ELECTRIC") AND DIAMOND MERGER SUB, INC., ("SUB") A WHOLLY-OWNED
         SUBSIDIARY OF A WHOLLY-OWNED SUBSIDIARY OF GENERAL ELECTRIC.
 
Dear Mr. Carroll:
 
    Enclosed for your information is a true, correct & complete copy of the form
of Merger Agreement, which among other things, provides for the merger of Sub
into InnoServ, with InnoServ being the surviving corporation and becoming a
wholly-owned subsidiary of a wholly-owned subsidiary of General Electric (the
"Merger"). Capitalized terms not defined herein shall have the meaning given to
each in the Merger Agreement.
 
    Pursuant to Section 1.2(a) of the stock purchase agreement dated November
13, 1997 (the "Stock Purchase Agreement"), among InnoServ, MEDIQ Incorporated
("MEDIQ") and MEDIQ Investment Services, Inc. ("MIS" and together with MEDIQ,
the "Former Holder"), InnoServ agreed not to enter into or consummate a Change
of Control (as defined in the Stock Purchase Agreement") unless the other party
or parties thereto agree, as a condition precedent to such transaction, to pay
to Former Holder, certain consideration based on the date of entering into or
consummating a Change of Control. You have advised us that you believe that the
amount of such consideration, based on the warranties and representations
hereinafter set forth, should be $4,052,876.00. InnoServ believes that the
amount of such payment should be $3,218,997.00. Accordingly, by the execution
and delivery of this letter, InnoServ and MEDIQ agree to submit such dispute to
arbitration pursuant to Section 5.13 of the Stock Purchase Agreement no later
than 20 days after the date hereof and to direct the arbitrators to resolve such
dispute as soon as reasonably possible following such submission. The Merger
Agreement provides for the payment on the Effective Date by General Electric (i)
to the Former Holder of an amount equal to $3,218,997.00 and (ii) to an escrow
agent of an amount equal to $833,879.00 to be held in escrow pending the
resolution of, and thereupon be paid as provided by, such arbitration
(collectively, the "MEDIQ Obligation"), pursuant to an agreement substantially
in the form of Attachment B.
 
    In order to induce the Former Holder to enter into this letter agreement,
InnoServ and General Electric each hereby represent and warrant that (i) it, in
good faith, did not delay or defer the consideration, evaluation or negotiation
of the Merger Agreement with the intent to reduce any amounts payable to Former
Holder pursuant to the Stock Purchase Agreement, and (ii) the chronology
enclosed with this letter agreement as Attachment A is a general description of
the activities which InnoServ and
 
                                     A-V-1
<PAGE>
General Electric have undertaken from the Fall of 1997 through the date hereof
with respect to the possibility of entering into a possible business
combination, and such chronology is true and correct in all material respects
and does not omit to state any facts necessary to make the statements therein
not materially misleading. Notwithstanding the foregoing warranty and
representation with respect to the chronology, each of InnoServ and General
Electric warrant and represent only with respect to the matters undertaken
solely by such party.
 
    Please acknowledge, by signing and returning a copy of this letter to me,
that: (i) upon execution and delivery of the Merger Agreement in substantially
the same form as the enclosed agreement and satisfaction on the Effective Date
of the MEDIQ Obligation, neither the Former Holder nor any of its subsidiaries
will have any claims against InnoServ or any of its subsidiaries, directors or
officers (collectively, the "InnoServ Group") or General Electric or any of its
subsidiaries, directors or officers (collectively, the "GE Group") with respect
to the Stock Purchase Agreement and the execution, delivery, performance or
consummation of the Merger Agreement, and subject to the satisfaction on the
Effective Date of the MEDIQ Obligation, hereby irrevocably releases the InnoServ
Group and the GE Group from and against, and irrevocably waives, any and all
claims, liabilities, obligations, covenants, agreements, damages and causes of
action (collectively, "Claims") which it may have against the InnoServ Group or
the GE Group arising out of any event or agreement occurring prior to the date
hereof with respect to the Stock Purchase Agreement and the execution, delivery,
performance or consummation of the Merger Agreement, and (ii) upon satisfaction
on the Effective Date of the MEDIQ Obligation all obligations of the InnoServ
Group under the Stock Purchase Agreement shall be satisfied in full and the
Former Holder will have no further Claims against the InnoServ Group or the GE
Group with respect to the Stock Purchase Agreement and the execution, delivery,
performance or consummation of the Merger Agreement.
 
    Upon consummation of the Merger, neither the InnoServ Group nor the GE Group
will have any claims against the Former Holder or any of its subsidiaries,
directors or officers (collectively, the "MEDIQ Group") with respect to the
Stock Purchase Agreement and the execution, delivery, performance or
consummation of the Merger Agreement, and subject to the consummation of the
Merger, each hereby irrevocably releases the MEDIQ Group from and against, and
irrevocably waives, any and all Claims which it may have against the MEDIQ Group
arising out of the Stock Purchase Agreement and the execution, delivery,
performance, or consummation of the Merger Agreement.
 
    The foregoing releases and acknowledgments are subject to the accuracy of
the representations and warranties of InnoServ and General Electric set forth in
this letter and do not affect the parties' rights to the amount held in escrow
pursuant to this letter, which rights shall be determined with arbitration.
 
Sincerely yours,

              CHAPTER 13 OF THE CALIFORNIA GENERAL CORPORATION LAW
 
SECTION 1300.  REORGANIZATION OR SHORT-TERM MERGER; DISSENTING SHARES; CORPORATE
               PURCHASE AT FAIR MARKET VALUE; DEFINITIONS
 
    (a) If the approval of the outstanding shares (Section 152) of a corporation
is required for a reorganization under subdivisions (a) and (b) or subdivision
(e) or (f) of Section 1201, each shareholder of the corporation entitled to vote
on the transaction and each shareholder of a subsidiary corporation in a
short-form merger may, by complying with this chapter, require the corporation
in which the shareholder holds shares to purchase for cash at their fair market
value the shares owned by the shareholder which are dissenting shares as defined
in subdivision (b). The fair market value shall be determined as of the day
before the first announcement of the terms of the proposed reorganization or
short-form merger, excluding any appreciation or depreciation in consequence of
the proposed action, but adjusted for any stock split, reverse stock split, or
share dividend which becomes effective thereafter.
 
    (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:
 
        (1) Which were not immediately prior to the reorganization or short-form
    merger either (A) listed on any national securities exchange certified by
    the Commissioner of Corporations under subdivision (o) of Section 25100 or
    (B) listed on the list of OTC margin stocks issued by the Board of Governors
    of the Federal Reserve System, and the notice of meeting of shareholders to
    act upon the reorganization summarizes this section and Sections 1301, 1302,
    1303 and 1304; provided, however, that this provision does not apply to any
    shares with respect to which there exists any restriction on transfer
    imposed by the corporation or by any law or regulation; and provided,
    further, that this provision does not apply to any class of shares described
    in subparagraph (A) or (B) if demands for payment are filed with respect to
    5 percent or more of the outstanding shares of that class.
 
        (2) Which were outstanding on the date for the determination of
    shareholders entitled to vote on the reorganization and (A) were not voted
    in favor of the reorganization or, (B) if described in subparagraph (A) or
    (B) of paragraph (1) (without regard to the provisos in that paragraph),
    were voted against the reorganization, or which were held of record on the
    effective date of a short-form merger; provided, however, that subparagraph
    (A) rather than subparagraph (B) of this paragraph applies in any case where
    the approval required by Section 1201 is sought by written consent rather
    than at a meeting.
 
        (3) Which the dissenting shareholder has demanded that the corporation
    purchase at their fair market value, in accordance with Section 1301.
 
    (c) As used in this chapter, "dissenting shareholder" means the record
holder of dissenting shares and includes a transferee of record.
 
SECTION 1301.  NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND
               FOR PURCHASE; TIME; CONTENTS
 
    (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.
The statement of price constitutes an offer by the corporation to purchase at
the
 
                                     A-VI-1
<PAGE>
price stated any dissenting shares as defined in subdivision (b) of Section

corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon

by the shareholder which the shareholder demands that the corporation purchase
and shall contain a statement of what such shareholder claims to be the fair
market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

               SECURITIES
 
    Within 30 days after the date on which notice of the approval by the

mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.
 
SECTION 1303.  PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR
               MARKET VALUE; FILING; TIME OF PAYMENT
 
    (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.
 
    (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,

    (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding
 
                                     A-VI-2
<PAGE>
purchase of such shares as dissenting shares or any interested corporation,

outstanding shares (Section 152) or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder, but not thereafter, may file a

determine whether the shares are dissenting shares or the fair market value of
the dissenting shares or both or may intervene in any action pending on such a
complaint.
 
    (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
    (c) On the trial of the action, the court shall determine the issues. If the
status of the shares as dissenting shares is in issue, the court shall first

appraisers to determine, the fair market value of the shares.
 
SECTION 1305.  REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT;
               JUDGMENT; PAYMENT; APPEAL; COSTS

the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.
 
    (b) If a majority of the appraisers appointed fail to make and file a report
within 10 days from the date of their appointment or within such further time as
may be allowed by the court or the report is not confirmed by the court, the
court shall determine the fair market value of the dissenting shares.
 
    (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.
 
    (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.
 
    (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.
 
    (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.
