                           San Bruno, California 94066

                               September 19, 1996

Dear Axion Stockholder:

     A Special Meeting of stockholders of Axion Inc. ("Axion") will be held on
October 18, 1996, at 8:00 a.m., local time, at the offices of Gunderson Dettmer
Stough Villeneuve Franklin & Hachigian, LLP, legal counsel to Axion, located at
600 Hansen Way, Second Floor, Palo Alto, California 94304. Enclosed are a Notice
of Special Meeting of Stockholders, a Proxy Statement/Prospectus and a Proxy
relating to the Special Meeting.

     At the Special Meeting, you will be asked to consider and vote upon a
proposal described in the Proxy Statement/Prospectus to adopt and approve the
Amended and Restated Agreement and Plan of Merger, dated as of August 2, 1996
(the "Merger Agreement"), by and among Axion, Bristol-Myers Squibb Company, a
Delaware corporation ("BMS"), and OTN Acquisition Sub Inc., a Delaware
corporation and a wholly owned subsidiary of BMS ("BMS Sub"), whereby BMS Sub
will merge with and into Axion (the "Merger") and Axion will survive the Merger
as a wholly owned subsidiary of BMS (the "Merger Proposal").


     At the Special Meeting, holders of Axion Preferred Stock will also be asked
to consider and vote upon a proposal described in the Proxy Statement/Prospectus
to convert each issued and outstanding share of Axion Preferred Stock into one
fully paid and nonassessable share of Axion Common Stock and to determine that
the Merger and related transactions do not constitute a liquidation of Axion
under its charter (the "Preferred Stock Proposal"). It is a condition to the
respective obligations of each party to the Merger Agreement that the Preferred
Stock Proposal be approved.

     Immediately prior to the Merger, all options to purchase shares of Axion
Common Stock will be exercised or canceled and the Preferred Stock Proposal will
be implemented. In the Merger, holders of Axion Common Stock will receive shares
of BMS Common Stock with an aggregate value of $86,000,000 (subject to increase
or decrease if the value of BMS Common Stock fluctuates outside a certain
range). A portion of such BMS Common Stock, with an aggregate value of
$5,000,000, will be placed in escrow to secure certain contingent
indemnification obligations to BMS.

     Also immediately prior to the Merger, Axion will spin off to its
stockholders (the "Distribution") all the stock of its wholly owned subsidiary,
Axion HealthCare Inc. ("AHC"), which will own certain assets and businesses of
Axion which will not be acquired in the Merger by BMS. These businesses and
assets, which include Axion's cancer-specific managed care services business,
its oncology-related drug and treatment information computer software business
and related supporting management information systems, are described in greater
detail in the Information Statement included as Appendix G to the Proxy
Statement/Prospectus. AHC will place $5,000,000 in cash in escrow to secure
certain contingent indemnification obligations to BMS. You will not be asked to
vote on the Distribution, which is not subject to stockholder approval.


     The Merger and the Distribution should be tax-free to Axion stockholders.

<PAGE>



   
     After careful consideration, the Board of Directors of the Company has
unanimously determined that the Merger is fair to, and in the best interests of,
the Company and its stockholders and unanimously recommends that the
stockholders of the Company vote FOR the adoption and approval of the Merger
Agreement and that the holders of Axion Preferred Stock vote FOR the Preferred
Stock Proposal.

     Adoption and approval of the Merger Proposal requires (a) at least a
majority of the votes entitled to be cast by the holders of the outstanding
shares of Axion Common Stock and Axion Preferred Stock voting together as a
single class and (b) at least a majority of the votes entitled to be cast by the
holders of the outstanding shares of Axion Preferred Stock voting together as a
single class. Approval of the Preferred Stock Proposal requires the affirmative
vote of at least 66 2/3% of the votes entitled to be cast by holders of Axion
Preferred Stock, voting as a single class. If the Merger is not consummated, the
Preferred Stock Proposal will not be implemented.

     Record holders and beneficial owners of (a) approximately 82.6% of the
outstanding shares of Axion Common Stock and Axion Preferred Stock and (b)
approximately 85.2% of the outstanding shares of Axion Preferred Stock have
entered into an agreement with BMS and BMS Sub pursuant to which each such
stockholder has agreed to, among other things, vote all of its/his shares of
such stock in favor of approval of the Merger and the Preferred Stock Proposal.
Accordingly, the Merger and the Preferred Stock Proposal can be approved by the
affirmative vote of such persons even if all other Axion stockholders vote
against the Merger and the Preferred Stock Proposal. The Merger is expected to
be consummated promptly after the Special Meeting.

     The Proxy Statement/Prospectus included in the materials accompanying this
letter more fully describes the proposed Merger and related transactions and
includes information about BMS and Axion.
    

     All stockholders are cordially invited to attend the Special Meeting in
person. However, whether or not you plan to attend the Special Meeting, please
complete, sign, date and return your proxy card in the enclosed self-addressed
postage paid envelope. If you attend the Special Meeting, you may vote in person
if you wish, even though you have previously returned your proxy card. It is
important that your shares be represented and voted at the Special Meeting.


                                       Sincerely,



                                       MICHAEL D. GOLDBERG

                    NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

   
                         To Be Held on October 18, 1996



     Notice is hereby given that a Special Meeting of Stockholders of Axion Inc.
("Axion") will be held on October 18, 1996, at 8:00 a.m., local time, at the
offices of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, legal
counsel to Axion, located at 600 Hansen Way, Second Floor, Palo Alto, California
94304, for the following purposes:

     (1) For holders of Axion Preferred Stock, to consider and vote upon a
proposal (a) to convert each issued and outstanding share of Axion Preferred
Stock into fully paid and nonassessable shares of Axion Common Stock at an
applicable conversion price (the "Preferred Stock Conversion") and (b) to
determine that the Merger and the Distribution (each as defined below) and
related transactions do not constitute a liquidation, dissolution or winding up
of Axion under its amended and restated certificate of incorporation (the
"Preferred Stock Proposal"); and

     (2) For all stockholders, to consider and vote upon a proposal to adopt and
approve the Amended and Restated Agreement and Plan of Merger, dated as of
August 2, 1996 (the "Merger Agreement"), by and among Axion, Bristol-Myers
Squibb Company, a Delaware corporation ("BMS"), and OTN Acquisition Sub Inc., a
Delaware corporation and wholly owned subsidiary of BMS ("BMS Sub"), pursuant to
which, among other things, BMS Sub will merge with and into Axion (the "Merger")
and Axion will survive the Merger as a wholly owned subsidiary of BMS, all as
more fully described in the accompanying Proxy Statement/Prospectus, including
the Appendices thereto (the "Merger Proposal"). Immediately prior to the Merger,
all options to purchase shares of Axion Common Stock will be exercised or
canceled, following which Axion will distribute to its stockholders (the
"Distribution") all the stock of a subsidiary which will own certain assets and
businesses of Axion which will not be acquired in the Merger by BMS. These
assets and businesses are more fully described in the Information Statement
included as Appendix G to the Proxy Statement/Prospectus. Immediately after the
Distribution and immediately prior to the Merger, the Preferred Stock Conversion
will be implemented.

     At the time the Merger becomes effective (the "Effective Time"), (a) each
issued and outstanding share of Axion Common Stock (other than any shares of
Axion Common Stock owned by Axion or any subsidiary of Axion or BMS or any
wholly owned subsidiary of BMS and any shares held by Axion stockholders who
perfect, under Delaware law, their right to dissent to the Merger) will be
converted into the right to receive the number of fully paid and nonassessable
shares of common stock, par value $.10 per share, of BMS (together with the
Rights associated with such common stock) (collectively, "BMS Common Stock")
determined as provided in the Merger Agreement, (b) each share of Axion Common
Stock owned by Axion or any subsidiary of Axion or BMS or any wholly owned
subsidiary of BMS will be canceled and retired without payment of any
consideration therefor and will cease to exist, and (c) a portion of the BMS
Common Stock to be received by Axion stockholders in the Merger will be held and
made subject to an escrow to secure certain contingent indemnification
obligations of such Axion stockholders and Axion and certain of its subsidiaries
to BMS.

     (3) To vote on any other matter that may properly come before the Special
Meeting and at any adjournments or postponements thereof.

   
     The close of business on August 31, 1996, has been fixed as the record date
for determining the Axion stockholders entitled to receive notice of and to vote
at the Special Meeting or any adjournment or postponements thereof. A complete
list of the stockholders entitled to vote at the Special Meeting will be
available during the 10 days prior to the Special Meeting at Axion's principal
executive offices located at 1111 Bayhill Drive, Suite 125, San Bruno,
California 94066 for examination by any stockholder and will also be available
for inspection at the Special Meeting.

     Adoption and approval of the Merger Proposal requires (a) at least a
majority of the votes entitled to be cast by the holders of the outstanding
shares of Axion Common Stock and Axion Preferred Stock voting together as a
single class and (b) at least a majority of the votes entitled to be cast by the
holders of the outstanding shares of Axion Preferred Stock voting together as a
single class. Approval of the Preferred Stock Proposal requires the affirmative
vote of at least 66 2/3% of the votes entitled to be cast by holders of Axion
Preferred Stock, voting as a single class. It is a condition to the respective
obligations of each party to the Merger Agreement that the Preferred Stock
Proposal be approved. If the Merger is not consummated, the Preferred Stock
Conversion will not be implemented.

     Record holders and beneficial owners of (a) approximately 82.6% of the
outstanding shares of Axion Common Stock and Axion Preferred Stock and (b)
approximately 85.2% of the outstanding shares of Axion Preferred Stock have
entered into an agreement with BMS and BMS Sub pursuant to which each such
stockholder has agreed to, among other things, vote all of its/his shares of
such stock in favor of approval of the Merger Proposal and the Preferred Stock
Proposal. Accordingly, the Merger Proposal and the Preferred Stock Proposal can
be approved by the affirmative vote of such persons even if all other Axion
stockholders vote against the Merger Proposal and the Preferred Stock Proposal.
The Merger is expected to be consummated promptly after the Special Meeting.

     Holders of shares of Axion Common Stock will be entitled to dissenters'
rights in connection with the Merger as provided in the Merger Agreement and as
more fully described in the accompanying Proxy Statement/Prospectus.

     The accompanying Proxy Statement/Prospectus describes in detail the
proposed Merger, the Merger Agreement and the transactions contemplated thereby.
Such Proxy Statement/Prospectus and the Appendices thereto (including the Merger
Agreement attached as Appendix A thereto) form a part of this Notice.

     The proposed Merger is of great importance to Axion and its stockholders.
Please read the Proxy Statement/Prospectus carefully and then complete, sign and

                                 PROXY STATEMENT
                            -------------------------

                          BRISTOL-MYERS SQUIBB COMPANY
                                   PROSPECTUS

   
     This Proxy Statement/Prospectus is being furnished to the stockholders of
Axion Inc., a Delaware corporation ("Axion"), in connection with the
solicitation of proxies by the Board of Directors of Axion (the "Axion Board")
from holders of outstanding shares of common stock, par value $.001 per share,
of Axion (the "Axion Common Stock") and holders of outstanding shares of each
series of preferred stock, par value $.001 per share, of Axion (the "Axion
Preferred Stock"), for use at the Special Meeting of stockholders of Axion to be
held on October 18, 1996, and at any adjournments or postponements thereof (the
"Special Meeting").

     At the Special Meeting, (i) stockholders of Axion will be asked to consider
and vote upon a proposal (the "Merger Proposal") to approve and adopt the
Amended and Restated Agreement and Plan of Merger, dated as of August 2, 1996,
among Bristol-Myers Squibb Company, a Delaware corporation ("BMS"), OTN
Acquisition Sub Inc., a Delaware corporation and a wholly owned subsidiary of
BMS ("BMS Sub"), and Axion, which is attached as Appendix A to this Proxy
Statement/Prospectus and is incorporated herein by reference (as it may be
amended, supplemented or otherwise modified from time to time, the "Merger
Agreement") and the transactions contemplated by the Merger Agreement, including
the Merger (as defined herein), and (ii) holders of Axion Preferred Stock will
be asked to consider and vote upon a proposal (the "Preferred Stock Proposal")
(a) to convert, immediately after the Distribution (as defined herein) and
immediately prior to the Merger, each issued and outstanding share of Axion
Preferred Stock into one fully paid and nonassessable share of Axion Common
Stock (the "Preferred Stock Conversion") and (b) to determine that the Merger,
the Distribution and related transactions do not constitute a liquidation,
dissolution or winding up of Axion under its amended and restated certificate of
incorporation (the "Axion Certificate of Incorporation"). The Merger Agreement
provides, subject to the satisfaction or waiver of certain conditions, that (i)
Axion will effect the distribution (the "Distribution") as contemplated by the
Agreement and Plan of Reorganization and Distribution to be entered into among
Axion, Axion HealthCare Inc., a Delaware corporation and a wholly owned
subsidiary of Axion ("AHC"), OPUS Health Systems Inc., a Delaware corporation
and a wholly owned subsidiary of Axion ("OPUS"), Oncology Therapeutics Network
Corporation, a Delaware corporation and a wholly owned subsidiary of Axion
("OTNC"), OPUS Sub, Inc., a Delaware corporation to be formed as a wholly owned
subsidiary of OPUS ("OPUS Sub"), and Oncology Therapeutics Network Joint
Venture, L.P., a Delaware limited partnership ("OTN" or the "Partnership"), the
form of which is attached as Appendix B to this Proxy Statement/Prospectus and
is incorporated herein by reference (as it may be amended, supplemented or
otherwise modified from time to time, the "Distribution Agreement") pursuant to
which Axion will distribute to the holders of Axion Common Stock and the holders
of Axion Preferred Stock all the then outstanding shares of preferred stock, par
value $.0001, of AHC (the "AHC Preferred Stock"), (ii) immediately after the
Distribution and immediately prior to the Merger, the Preferred Stock Conversion
will be implemented and (iii) BMS Sub will immediately thereafter be merged with
and into Axion (the "Merger"), with Axion surviving the Merger (sometimes
hereinafter referred to as the "Surviving Corporation").
    

     At the time the Merger becomes effective (the "Effective Time"), each share
of Axion Common Stock outstanding immediately prior to the Effective Time (other
than any shares of Axion Common Stock owned by Axion or any subsidiary of Axion
or BMS or any subsidiary of BMS and any Dissenting Shares (as defined herein))
will be converted into the right to receive the number (the "Conversion Number")
of fully paid and nonassessable shares of common stock, par value $.10 per
share, of BMS together with the associated rights (the "BMS Rights") pursuant to
the Rights Agreement dated as of December 4, 1987 (as amended, the "Rights
Agreement") between BMS and The Chase Manhattan Bank, as Rights Agent
(collectively, "BMS Common Stock"), equal to the quotient of (a)(i) $86,000,000
divided by (ii) the Average Value of BMS Common Stock (as defined herein)
divided by (b) the number of shares of Axion Common Stock outstanding
immediately prior to the Effective Time (calculated on a fully diluted basis
assuming that each share of Axion Preferred Stock outstanding immediately prior
to the Effective Time has been converted in accordance with its terms into one
share of Axion Common Stock and that all options, warrants or other rights to
acquire Axion Common Stock ("Axion Options") outstanding immediately 


                                        1

prior to the Effective Time have been exercised or canceled and the related
subject shares (other than any subject shares related to any portion of any
Axion Option that shall have been canceled and not exercised) of Axion Common
Stock are outstanding (collectively, the "Diluted Share Assumption")). In the
event that as of the closing date of the Merger (the "Closing Date") the Average
Value of BMS Common Stock is less than $82.73 (the "Minimum Price"), then the
Average Value of BMS Common Stock will be deemed to be an amount equal to the
Minimum Price, and in the event that as of the Closing Date the Average Value of
BMS Common Stock is greater than $91.43 (the "Maximum Price"), then the Average
Value of BMS Common Stock will be deemed to be an amount equal to the Maximum
Price, in each case subject to certain adjustments for dividends.

     Based on the Diluted Share Assumption (and assuming exercise of all Axion
Options other than the Goldberg $10.00 Options (as defined herein), resulting in
an aggregate of 9,970,509 shares of Axion Common Stock outstanding), and
assuming an Average Value of BMS Common Stock equal to $92.83 (the average per
share closing price of BMS Common Stock for the 10 full NYSE trading days ending
September 18, 1996, the most recent full NYSE trading day available prior to
printing this Proxy Statement/Prospectus), in which event the Conversion Number
would be calculated based on an Average Value of BMS Common Stock equal to the
Maximum Price of $91.43, (a) the Conversion Number would be 0.094 and (b)
assuming a market value of the BMS Common Stock on the date received by holders
of Axion Common Stock in the Merger of $92.83, the aggregate market value of BMS
Common Stock to be received by holders of Axion Common Stock in the Merger would
be approximately $87 million, or approximately $8.73 per share of Axion Common
Stock. There can be no assurance that these assumptions will be true as of the
Effective Time.

     The Average Value of BMS Common Stock is determined as of five full NYSE
trading days immediately preceding the Effective Time (which date may be after
the date of the Special Meeting), at which time the Average Value of BMS Common
Stock may be less than the assumed $92.83 Average Value of BMS Common Stock
referred to above and indeed may be less than the Minimum Price. If the Average
Value of BMS Common Stock at such time is between the Minimum Price ($82.73) and
the Maximum Price ($91.43), the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be $86 million, or
approximately $8.63 per share of Axion Common Stock (based on the Diluted Share
Assumption and assuming exercise of all Axion Options other than the Goldberg
$10.00 Options). If the Average Value of BMS Common Stock at such time is less
than the Minimum Price, the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be less, and may be
substantially less, than $86 million, or approximately $8.63 per share of Axion
Common Stock (based on the Diluted Share Assumption and assuming exercise of all
Axion Options other than the Goldberg $10.00 Options). The foregoing statements
in this paragraph assume that the market value of BMS Common Stock on the
Closing Date is equal to the Average Value of the BMS Common Stock used to
calculate the Conversion Number. However, the actual market value of BMS Common
Stock on the Closing Date may be substantially less than the Average Value of
BMS Common Stock used to calculate the Conversion Number. The actual aggregate
market value on the Closing Date of BMS Common Stock received by holders of
Axion Common Stock in the Merger will be equal to the number of shares of BMS
Common Stock issued in the Merger multiplied by the market value of the BMS
Common Stock on the Closing Date.

     Under the terms of the Merger Agreement, Axion does not have the right to
decline to consummate the Merger solely because either the Average Value of BMS
Common Stock used to calculate the Conversion Number is less than the Minimum
Price or because the actual market value of BMS Common Stock on the Closing Date
is less than the Average Value of BMS Common Stock used to calculate the
Conversion Number. Therefore, if the Merger Proposal is adopted and approved and
all other conditions to the Merger are satisfied (or waived by the party for
whose benefit any such condition exists) at or prior to the Effective Time,
Axion stockholders will assume the risk of a decline in the market value of BMS
Common Stock below the Minimum Price and the risk that the actual market value
of BMS Common Stock on the Closing Date is less than the Average Value of BMS
Common Stock used to calculate the Conversion Number and, accordingly, the risk
that the aggregate market value of BMS Common Stock to be received by the
holders of Axion Common Stock in the Merger will be substantially less than $86
million or approximately $8.63 per share

(based on the Diluted Share Assumption and assuming exercise of all Axion
Options other than the Goldberg $10.00 Options).

     In addition, the number of assumed outstanding shares of Axion Common Stock
for the purpose of calculating the Conversion Number is determined as of
immediately prior to the Effective Time (which date may be after the date of the
Special Meeting), at which time the actual number of outstanding shares of Axion
Common Stock may be greater than the assumed 9,970,509 shares referred to above.
Each share of Axion Common Stock will be converted in the Merger into the right
to receive the Conversion Number of shares of BMS Common Stock. Any increase in
the actual number of outstanding shares of Axion Common Stock as of immediately
prior to the Effective Time would result in a corresponding decrease in the
Conversion Number and, accordingly, in the number of shares of BMS Common Stock
to be received in respect of each share of Axion Common Stock. The maximum
number of shares of Axion Common Stock that may be outstanding as of immediately
prior to the Effective Time is 10,070,509 shares.

     See "Risk Factors--Risk of Decline in Average Value of BMS Common Stock
Prior to the Effective Time" and "The Merger--Terms of the Merger
Agreement--Conversion of Axion Common Stock in the Merger" and
"--Conditions--Conditions to Obligations of Axion".

     On the Closing Date, a portion of the BMS Common Stock to be received by
the stockholders of Axion as of immediately preceding the Effective Time
("Former Axion Stockholders"), with a value of $5,000,000 (the "Escrowed
Shares"), will be placed in escrow on behalf of such Former Axion Stockholders,
and AHC will place $5,000,000 in cash (the "Escrowed Cash") in escrow, to secure
certain obligations of the Former Axion Stockholders and AHC and certain of its
subsidiaries to indemnify the BMS Indemnified Parties (as defined herein) under
the Indemnification Agreement, the Tax Matters Agreement and the Escrow
Agreement (each as defined herein). There can be no assurance as to whether all
or any portion of such Escrowed Shares will eventually be released to such
Former Axion Stockholders or as to whether all or any portion of such Escrowed
Cash will eventually be released to AHC. See "Risk Factors--Indemnification
Obligations of the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries"
and "Indemnification Arrangements--Terms of the Indemnification Agreement",
"--Terms of the Tax Matters Agreement" and "--Terms of the Escrow Agreement".

     This Proxy Statement/Prospectus is first being mailed to Axion stockholders
on or about September 19, 1996.
    

     This Proxy Statement/Prospectus also constitutes the Prospectus of BMS
under the Securities Act of 1933 (the "Securities Act") for the public offering
of up to 1,039,526 shares of BMS Common Stock to be received by Axion
stockholders in the Merger. This Proxy Statement/Prospectus does not cover

Statement/Prospectus in connection with any such resale.

                                     SUMMARY
   
     The following summary is not intended to be complete and is qualified in
its entirety by the more detailed information included elsewhere in this Proxy
Statement/Prospectus, the Appendices hereto and the documents incorporated
herein by reference. Stockholders are urged to read carefully this Proxy
Statement/Prospectus, the Appendices hereto and the documents incorporated
herein by reference in their entirety.

     All information concerning Axion, AHC, OnCare, OTNC, OTN, OPUS, OPUS Sub
and their respective affiliates and subsidiaries (other than BMS) included in
this Proxy Statement/Prospectus and the Appendices hereto has been furnished by
Axion, and all information concerning BMS, BMS Sub and their respective
affiliates and subsidiaries (other than OTN) included in this Proxy
Statement/Prospectus, the Appendices hereto and the documents incorporated
herein by reference has been furnished by BMS.

    
   

     An Index of Defined Terms used herein is included at page [127] of this
Proxy Statement/Prospectus.

The Companies

     Axion

     Axion was incorporated under the laws of the State of Delaware on July 30,
1987. Axion is a holding company with three direct wholly owned subsidiaries,
OTNC, AHC and OPUS. OTNC is the general partner of the Partnership, which
distributes oncology drugs and related supplies to office-based oncologists (the
"OTN Business"). Bristol-Myers Oncology Therapeutic Network, Inc., a Delaware
corporation and a wholly owned subsidiary of BMS ("BMOTN"), is the limited
partner. Axion's investment in the Partnership constitutes Axion's principal
business, representing 98.2% and 99.9%, respectively, of Axion's consolidated
total revenues and all of Axion's consolidated income from operations during
1995 and for the six months ended June 30, 1996, and representing approximately
98.6% of Axion's consolidated total assets at June 30, 1996.

         AHC expects that its principal business will consist of providing
cancer-specific managed care services to cancer care payers and providers (the
"AHC Business"). The AHC Business has generated limited revenues and has
incurred losses since AHC's formation in 1994. AHC was formed to carry on the
clinical studies programs which Axion began in 1987 and to continue the
development of oncology disease management programs arising from such clinical
studies programs. OPUS consists of the OPUS Station Business (the "OPUS Station
Business") and the OPUS Matrix Business (the "OPUS Matrix Business"). The OPUS
Station Business furnishes automated drug dispensing and inventory tracking
systems to office-based oncology practices. The OPUS Station Business has not
generated significant revenues, and has operated at a loss since its inception
in 1994. The OPUS Matrix Business consists of (i) computer software which
provides office-based oncology practices with access to drug and treatment
information and (ii) the management information systems currently used to
support Axion's businesses. The OPUS Matrix Business has incurred losses since
its inception in 1994.

     Axion is also the beneficial owner of 2,700,000 shares of Series A
Redeemable Preferred Stock of OnCare (the "OnCare Preferred Stock"). OnCare is
an oncology physician practice management company formed by Axion in June 1995.
On December 31, 1995, Axion distributed to holders of Axion Common Stock,
holders of Axion Options and holders of Axion Preferred Stock all Axion's
holdings of shares of common stock of OnCare.

     As a result of the distribution of the Preference Amount (as defined
herein), the Contributions (as defined herein) and the Distribution, OTNC,
including its interest in the Partnership, and OPUS, which at the Effective Time
will include only the OPUS Station Business, including in each case the assets
and certain of the liabilities

relating thereto (collectively, the "Retained Business"), will constitute all
the businesses, assets and liabilities of Axion at the Effective Time.
Immediately prior to the time at which the Distribution is effected (the "Time
of Distribution"), all Axion's other businesses, assets and liabilities
(collectively, the "Acquired Business"), which will include the AHC Business,
the OPUS Matrix Business, the OnCare Preferred Stock, all cash and cash
equivalents of Axion and its subsidiaries (other than Retained Cash (as defined
herein)) and the Employee Loans (as defined herein) will be held by AHC.

     At June 30, 1996, Axion and its consolidated subsidiaries had total assets
of approximately $159.1 million and stockholders' equity of approximately $27.6
million, and the Retained Business had total assets of approximately $156.9
million, or approximately 98.6% of Axion's consolidated total assets, and
stockholders' equity of $26.9 million, or approximately 97.2% of Axion's
consolidated stockholders' equity. For the six months ended June 30, 1996, and
the year ended December 31, 1995, the Retained Business accounted for
approximately $133.1 million, or approximately 99.9%, and $195.3 million, or
approximately 98.2%, respectively, of Axion's consolidated net revenues. The
Acquired Business has not, to date, realized significant revenues, and has
operated and continues to operate at a loss, with funding provided by Axion.
    

     Axion's principal executive offices are located at 1111 Bayhill Drive,
Suite 125, San Bruno, California 94066, and its telephone number at such offices
is (415) 589-5900.

     BMS

   
     BMS was incorporated under the laws of the State of Delaware in August 1933
under the name Bristol-Myers Company as successor to a New York business started
in 1887. In 1989, the Bristol-Myers Company changed its name to Bristol-Myers
Squibb Company, as a result of a merger. BMS, through its divisions and
subsidiaries, is a major producer and distributor of pharmaceutical products,
medical devices, nonprescription health products, toiletries and beauty aids. At
June 30, 1996, BMS had total assets of approximately $13,750 million and
stockholders' equity of approximately $6,065 million.
    

     BMS's principal executive offices are located at 345 Park Avenue, New York,
New York 10154-0037 and its telephone number at such offices is (212) 546-4000.

     Additional Information

   
     To obtain additional information regarding the businesses of BMS and the
Retained Business, see "Available Information", "Incorporation of Certain
Information by Reference" and "The Companies". For information regarding the
businesses of AHC and the Acquired Business, see the Information Statement (the
"Information Statement") attached as Appendix G hereto.
    

The Transactions

   
     Pursuant to the transactions described in this Proxy Statement/Prospectus,
BMS will acquire the Retained Business, which consists of (i) OTNC, including
its interest in the Partnership, and (ii) OPUS, which at the Effective Time will
contain only the OPUS Station Business, including in each case the assets and
certain of the liabilities relating thereto.

     The proposals to be submitted to Axion stockholders at the Special Meeting
relate to the acquisition by BMS of the Retained Business. The acquisition of
the Retained Business by BMS will be effected through a series of sequential
transactions, including the Contributions, the Distribution and the Merger, all
as set forth in the Merger

Agreement and the Distribution Agreement. Prior to the Effective Time, the
Acquired Business will be transferred to AHC and its wholly-owned subsidiary,
OPUS Sub, and the AHC Preferred Stock will be distributed to the stockholders of
Axion in the Distribution. After the Distribution and at the Effective Time,
Axion will hold the Retained Business, so that BMS will effectively acquire the
Retained Business in the Merger. The purpose of this complex structure is to
permit the disposition of the Retained Business in a transaction that should be
tax free to Axion stockholders in which stockholders of Axion will receive BMS
Common Stock and will also retain their proportionate equity interests in the
Acquired Business in the form of AHC Preferred Stock to be received in the
Distribution. See "Risk Factors--Certain Federal Income Tax Consequences" and
"Certain Federal Income Tax Consequences". For information regarding the
Acquired Business and the AHC Preferred Stock, see the Information Statement
attached as Appendix G hereto.

     The significant sequential transactions that will be effected in order to
accomplish the Distribution and the Merger, all of which will take place at or
shortly before the Effective Time, are as follows: (i) pursuant to the
Distribution Agreement, the Partnership will distribute to OTNC, and OTNC will
distribute to Axion, an amount in cash equal to $13,615,147 (the "Preference
Amount"); (ii) the Employee Loans will be made and all Axion Options will be
exercised or canceled; (iii) pursuant to the Distribution Agreement, OPUS will

OPUS Sub to Axion; (v) pursuant to the Distribution Agreement, Axion will
contribute the stock of OPUS Sub and certain other tangible and intangible
assets of Axion and its subsidiaries, including the OnCare Preferred Stock, the
Employee Loans and an amount in cash equal to the Preference Amount (net of
Retained Cash), but excluding certain assets relating to the OTN Business and
the OPUS Station Business, to AHC, and AHC will assume all the liabilities of
Axion and its subsidiaries other than the liabilities assumed by OPUS Sub (which
will remain liabilities of OPUS Sub) and certain liabilities relating to the OTN
Business and the OPUS Station Business (the transactions in clauses (iii), (iv)
and (v), collectively, the "Contributions"); (vi) pursuant to the Distribution
Agreement, the issued and outstanding shares of common stock, par value $.0001
per share, of AHC ("AHC Common Stock"), all of which are held by Axion, will be
converted into the requisite number of shares of AHC Preferred Stock to effect
the Distribution; (vii) pursuant to the Distribution Agreement, in the
Distribution Axion will distribute to each holder of Axion Common Stock one
share of AHC Preferred Stock in respect of each share of Axion Common Stock held
by such holder on the Distribution Record Date (as defined below) and to each
holder of Axion Preferred Stock one share of AHC Preferred Stock in respect of
each share of Axion Preferred Stock held by such holder on the Distribution
Record Date; (viii) immediately after the Distribution and immediately prior to
the Merger, each issued and outstanding share of Axion Preferred Stock will be
converted into one fully paid and nonassessable share of Axion Common Stock; and
(ix) the Merger will be consummated pursuant to the Merger Agreement. See "The
Transactions" and "The Distribution".

     The Merger Agreement

     General. If the Merger Agreement is approved and adopted by the Axion
stockholders and the other conditions to the Merger are satisfied or waived, at
the Effective Time BMS Sub will be merged with and into Axion (which will then
hold only the Retained Business) with Axion as the Surviving Corporation, and
the separate existence of BMS Sub will cease.
    

     Pursuant to the Merger Agreement, at the Effective Time each issued and
outstanding share of Axion Common Stock (other than any shares of Axion Common
Stock owned by Axion or any subsidiary of Axion or BMS or any wholly owned
subsidiary of BMS and any Dissenting Shares) will be converted into the right to
receive the Conversion Number of fully paid and nonassessable shares of BMS
Common Stock (the "Merger Consideration").

The "Conversion Number" will be equal to the quotient of (a)(i) $86,000,000
divided by (ii) the Average Value of BMS Common Stock divided by (b) the number
of shares of Axion Common Stock outstanding immediately prior to the Effective
Time (calculated on a fully diluted basis assuming that each share of Axion
Preferred Stock outstanding immediately prior to the Effective Time has been
converted in accordance with its terms into one share of Axion Common Stock and
that all options, warrants or other rights to acquire Axion Common Stock ("Axion
Options") outstanding immediately prior to the Effective Time have been
exercised or canceled and that the related subject shares (other than any
subject shares related to any portion of any Axion Option that shall have been
canceled and not exercised) of Axion Common Stock are outstanding (collectively,
the "Diluted Share Assumption")). The term "Average Value of BMS Common Stock"
means an amount equal to the average of the per share closing prices of BMS
Common Stock as reported on the New York Stock Exchange Composite Transaction
Tape (the "NYSE Tape") for the 10 consecutive full NYSE trading days ending on
the fifth full NYSE trading day immediately preceding the Effective Time;
provided that (A) if the Board of Directors of BMS (the "BMS Board") declares a
cash dividend on the outstanding shares of BMS Common Stock having a record date
after the Effective Time but an ex-dividend date (based on "regular way" trading
on the NYSE of shares of BMS Common Stock, the "Ex-Date") that occurs during the
averaging period, then for purposes of computing the Average Value of BMS Common
Stock, the closing price on the Ex-Date and any trading day in the averaging
period after the Ex-Date will be adjusted by adding thereto the amount of such
dividend and (B) if the BMS Board declares a cash dividend on the outstanding
shares of BMS Common Stock having a record date before the Effective Time and an
Ex-Date that occurs during the averaging period, then for purposes of computing
the Average Value of BMS Common Stock, the closing price on any trading day
before the Ex-Date will be adjusted by subtracting therefrom the amount of such
dividend. Notwithstanding anything to the contrary contained in the Merger
Agreement, in the event that as of the closing date of the Merger (the "Closing
Date") the Average Value of BMS Common Stock is less than $82.73 (an amount
equal to 95 percent of the daily average per share closing price of BMS Common
Stock as reported on the NYSE Tape for the 10 full NYSE trading days immediately
prior to the date of the Merger Agreement) (the "Minimum Price"), then for the
purposes of calculating the Merger Consideration, the Average Value of BMS
Common Stock will be deemed to be an amount equal to the Minimum Price, and in
the event that as of the Closing Date the Average Value of BMS Common Stock is
greater than $91.43 (an amount equal to 105 percent of the daily average per
share closing price of BMS Common Stock as reported on the NYSE Tape for the 10
full NYSE trading days immediately prior to the date of the Merger Agreement)
(the "Maximum Price"), then for the purposes of calculating the Merger
Consideration, the Average Value of BMS Common Stock will be deemed to be the
Maximum Price. If, prior to the Effective Time, the BMS Board declares a stock
split, stock combination, stock dividend or other non-cash distribution on the
outstanding shares of BMS Common Stock, then the Minimum Price and Maximum Price
(and, if the Ex-Date for such event occurs during the averaging period, the
Average Value of BMS Common Stock) will be appropriately adjusted to reflect
such split, combination, dividend or other distribution.

     Based on the Diluted Share Assumption (and assuming exercise of all Axion
Options other than the Goldberg $10.00 Options, resulting in an aggregate of
9,970,509 shares of Axion Common Stock outstanding), and assuming an Average
Value of BMS Common Stock equal to $92.83 (the average per share closing price
of BMS Common Stock for the 10 full NYSE trading days ending September 18, 1996,
the most recent full NYSE trading day available prior to printing this Proxy
Statement/Prospectus), in which event the Conversion Number would be calculated
based on an Average Value of BMS Common Stock equal to the Maximum Price of
$91.43, (a) the Conversion Number would be 0.094 and (b) assuming a market value
of the BMS Common Stock on the date received by holders of Axion Common Stock in
the Merger of $92.83, the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger would be approximately
$87 million, or approximately $8.73 per share of Axion Common Stock. There can
be no assurance that these assumptions will be true as of the Effective Time.

     The Average Value of BMS Common Stock is determined as of five full NYSE
trading days immediately preceding the Effective Time (which date may be after
the date of the Special Meeting), at which time the Average Value of BMS Common
Stock may be less than the assumed $92.83 Average Value of BMS Common Stock
referred to above and indeed may be less than the Minimum Price. If the Average
Value of BMS Common Stock at such time is between the Minimum Price ($82.73) and
the Maximum Price ($91.43), the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be $86 million, or
approximately $8.63 per share of Axion Common Stock (based on the Diluted Share
Assumption and assuming exercise of all Axion Options other than the Goldberg
$10.00 Options). If the Average Value of BMS Common Stock at such time is less
than the Minimum Price, the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be less, and may be
substantially less, than $86 million, or approximately $8.63 per share of Axion
Common Stock (based on the Diluted Share Assumption and assuming exercise of all
Axion Options other than the Goldberg $10.00 Options). The foregoing statements
in this paragraph assume that the market value of BMS Common Stock on the
Closing Date is equal to the Average Value of the BMS Common Stock used to
calculate the Conversion Number. However, the actual market value of BMS Common
Stock on the Closing Date may be substantially less than the Average Value of
BMS Common Stock used to calculate the Conversion Number. The actual aggregate
market value on the Closing Date of BMS Common Stock received by holders of
Axion Common Stock in the Merger will be equal to the number of shares of BMS
Common Stock issued in the Merger multiplied by the market value of the BMS
Common Stock on the Closing Date.

     Under the terms of the Merger Agreement, Axion does not have the right to
decline to consummate the Merger solely because either the Average Value of BMS
Common Stock used to calculate the Conversion Number is less than the Minimum
Price or because the actual market value of BMS Common Stock on the Closing Date
is less than the Average Value of BMS Common Stock used to calculate the
Conversion Number. Therefore, if the Merger Proposal is adopted and approved and
all other conditions to the Merger are satisfied (or waived by the party for
whose benefit any such condition exists) at or prior to the Effective Time,
Axion stockholders will assume the risk of a decline in the market value of BMS
Common Stock below the Minimum Price and the risk that the actual market value
of BMS Common Stock on the Closing Date is less than the Average Value of BMS
Common Stock used to calculate the Conversion Number and, accordingly, the risk
that the aggregate market value of BMS Common Stock to be received by the
holders of Axion Common Stock in the Merger will be substantially less than $86
million or approximately $8.63 per share (based on the Diluted Share Assumption
and assuming exercise of all Axion Options other than the Goldberg $10.00
Options).


     In addition, the number of assumed outstanding shares of Axion Common Stock
for the purpose of calculating the Conversion Number is determined as of
immediately prior to the Effective Time (which date may be after the date of the
Special Meeting), at which time the actual number of outstanding shares of Axion
Common Stock may be greater than the assumed 9,970,509 shares referred to above.
Each share of Axion Common Stock will be converted in the Merger into the right
to receive the Conversion Number of shares of BMS Common Stock. Any increase in
the actual number of outstanding shares of Axion Common Stock as of immediately
prior to the Effective Time would result in a corresponding decrease in the
Conversion Number and, accordingly, in the number of shares of BMS Common Stock
to be received in respect of each share of Axion Common Stock. The maximum
number of shares of Axion Common Stock that may be outstanding as of immediately
prior to the Effective Time is 10,070,509 shares.

     See "Risk Factors--Risk of Decline in Average Value of BMS Common Stock
Prior to the Effective Time" and "The Merger--Terms of the Merger
Agreement-Conversion of Axion Common Stock in the Merger" and
"--Conditions--Conditions to Obligations of Axion".

     As of the Record Date, 1,606,651 shares of Axion Common Stock were
outstanding and 8,471,011 shares of Axion Common Stock were issuable upon
conversion of the Axion Preferred Stock and the exercise of Axion Options. The
approval of the Preferred Stock Proposal, the conversion of each issued and
outstanding share of Axion Preferred Stock into one fully paid and nonassessable
share of Axion Common Stock and the exercise or cancelation of all Axion
Options, in each case prior to the Effective Time, are each conditions to the
Merger. Michael D. Goldberg, the President and Chief Executive Officer of Axion,
has advised Axion that he does not intend to exercise his Axion Options to
purchase 100,000 shares of Axion Common Stock at a price of $10.00 per share
(the "Goldberg $10.00 Options"). Accordingly, the Goldberg $10.00 Options will
be canceled prior to the Effective Time, and assuming the conversion of each
issued and outstanding share of Axion Preferred Stock and the exercise of all
Axion Options other than the Goldberg $10.00 Options, it is anticipated that
there will be approximately 9,970,509 shares of Axion Common Stock issued and
outstanding on the Closing Date.

     On the Closing Date, a portion of the BMS Common Stock to be received by
Former Axion Stockholders in the Merger, with a value of $5,000,000 (the
"Escrowed Shares"), will be placed in escrow on behalf of such Former Axion
Stockholders, and AHC will place $5,000,000 in cash (the "Escrowed Cash") in
escrow to secure certain obligations of such Former Axion Stockholders and AHC
and certain of its subsidiaries to indemnify the BMS Indemnified Parties (as
defined herein) under the Indemnification Agreement, the Tax Matters Agreement
and the Escrow Agreement (each as defined herein). The indemnification
obligations of each of the Former Axion Stockholders under the Indemnification
Agreement will be limited in amount to the Escrowed Shares, except in certain
circumstances involving fraud, intentional misrepresentation or intentional
breach of a covenant by any such Former Axion Stockholder. The indemnification
obligations of AHC and the 81% AHC Subsidiaries will not be limited in amount to
the Escrowed Cash. There can be no assurance as to whether all or any portion of
such Escrowed Shares will eventually be released to such Stockholders or as to
whether all or any portion of such Escrowed Cash will eventually be released to
AHC or that the indemnification obligations of AHC and its subsidiaries will not
exceed the Escrowed Cash. There can be no assurance that the failure to obtain
the release of all or a portion of such Escrowed Cash or the incurrence of
indemnification obligations in excess of the Escrowed Cash will not have a
material adverse effect on AHC. See "Risk Factors--Indemnification Obligations
of the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries" and
"Indemnification Arrangements--Terms of the Indemnification Agreement", "--Terms
of the Tax Matters Agreement" and "--Terms of the Escrow Agreement".

     Fractional Shares. No fractional shares of BMS Common Stock will be issued
in the Merger. The Merger Agreement provides that each Axion stockholder who
otherwise would have been entitled to receive a fraction of a share of BMS
Common Stock will receive, in lieu thereof, cash (without interest) in an
amount, less the amount of any withholding taxes which may be required thereon,
equal to such fractional part of a share of BMS Common Stock multiplied by the
per share closing price of BMS Common Stock as reported on the NYSE Tape on the
full NYSE trading day immediately preceding the Closing Date.

     Effective Time; Closing. The Merger will become effective and the Effective
Time will occur immediately upon the filing of a certificate of merger (the
"Certificate of Merger") with the Delaware Secretary of State or at such time
thereafter as is provided in the Certificate of Merger. The Merger Agreement
provides that the closing (the "Closing") of the Merger will take place on a
date to be specified by the parties which date will be no later than the first
business day after satisfaction (or waiver by the party for whose benefit any
such condition exists) of the conditions to the Merger Agreement, unless another
date is agreed to in writing by BMS, BMS Sub and Axion. See "The
Merger--Effective Time; Closing".

     Distribution of Merger Consideration; Exchange of Share Certificates. At or
immediately after the Closing Date, BMS will send each Former Axion Stockholder
a letter (the "Letter of Transmittal") notifying such stockholder of the
consummation of the Merger and setting forth instructions for the surrender of
certificates (the "Certificates")

that before the Effective Time represented Axion Common Stock. Promptly after
receipt by BMS's exchange agent (the "Exchange Agent") of any Certificates
surrendered in accordance with the instructions set forth in the Letter of
Transmittal, the Exchange Agent will distribute to the Former Axion Stockholder
entitled thereto the certificates representing whole shares of BMS Common Stock
and a check in lieu of fractional shares of BMS Common Stock into which the
shares of Axion Common Stock represented by the surrendered Certificates were
converted in the Merger. The new certificates shall not include the number of
Escrowed Shares deemed to have been placed in escrow by such Former Axion
Stockholder. AXION STOCKHOLDERS ARE REQUESTED NOT TO SURRENDER THEIR
CERTIFICATES REPRESENTING OUTSTANDING SHARES OF AXION COMMON STOCK FOR EXCHANGE
UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL FROM BMS. See "The Merger--Exchange
of Certificates in the Merger".

     Execution and delivery of the Letter of Transmittal by each Former Axion
Stockholder will result in each such Former Axion Stockholder irrevocably
appointing AHC as his/her or its agent and attorney-in-fact to execute and
deliver on such Former Axion Stockholder's behalf, and thereby result in each
such Former Axion Stockholder becoming a party to and bound by, the
Indemnification Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution and delivery of the Letter of Transmittal will result in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder that may be necessary in connection with the transactions
contemplated by such agreements, including to give and receive notices on each
such Former Axion Stockholder's behalf and to represent each such Former Axion
Stockholder with respect to any matter, suit, claim, action or proceeding
arising with respect to any transaction contemplated by such agreements,
including the defense, appeal or settlement of any claim, action or proceeding
for which each such Former Axion Stockholder, may be obligated to indemnify any
person pursuant to such agreements or may be entitled to indemnification
pursuant to such agreements or which may be brought by BMS against each such
Former Axion Stockholder to enforce such indemnity; and will result in each such
Former Axion Stockholder ratifying and confirming any action taken by AHC in the
exercise of the power of attorney granted thereby. See "The Merger--Exchange of
Certificates in the Merger" and "--Indemnification Arrangements; Escrow;
Appointment of AHC as Representative" and "Indemnification Arrangements--Terms
of the Indemnification Agreement", "--Terms of the Tax Matters Agreement" and
"--Terms of the Escrow Agreement". Such agreements will, among other things,
subject each such Former Axion Stockholder as well as AHC and certain of its
subsidiaries to certain indemnity obligations to BMS and certain of its
subsidiaries and provide for the Escrowed Shares and the Escrowed Cash to be
placed in escrow to secure these obligations. See "Risk Factors--Indemnification
Obligations of the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries".
    

     Stock Exchange Listing. BMS has agreed in the Merger Agreement to use its
reasonable best efforts to cause the shares of BMS Common Stock issued in the
Merger to be approved for listing on the NYSE, subject to official notice of
issuance, prior to the Closing Date. Such approval for listing is a condition to
the obligation of each of BMS, BMS Sub and Axion to consummate the Merger. See
"The Merger--Stock Exchange Listing" and "--Conditions--Conditions to Each
Party's Obligation to Effect the Merger".

   
     Conditions. The Merger Agreement provides that the respective obligation of
each party to effect the Merger is subject to certain conditions, including the
approval of the Merger Proposal by the stockholders of Axion, the approval of
the Preferred Stock Proposal by holders of Axion Preferred Stock, the receipt
and reaffirmation of opinions with respect to the tax consequences of the Merger
and the Distribution, respectively, consummation of the Contributions and the
Distribution, the absence of certain material adverse changes, the receipt of
certain regulatory approvals and, in the case of BMS, the exercise or
cancelation of all outstanding Axion Options, the conversion of all shares of
Axion Preferred Stock into shares of Axion Common Stock, the absence of Axion
indebtedness in excess of specified levels and the absence of Dissenting Shares.
See "The Merger--Conditions".

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

     Termination. The Merger Agreement may be terminated at any time prior to
the Effective Time, whether before or after approval of matters presented in
connection with the Merger by the stockholders of Axion: (a) by mutual written
consent of BMS, BMS Sub and Axion; (b) by either BMS or Axion: (i) if, upon a
vote at the Special Meeting or any adjournment thereof, any required approval of
the stockholders of Axion shall not have been obtained; (ii) if the Merger shall
not have been consummated on or before October 31, 1996, unless the failure to
consummate the Merger is the result of a wilful and material breach of the
Merger Agreement by the party seeking to terminate the Merger Agreement;
provided, however, that the passage of such period will be tolled for any part
thereof (but in no event beyond December 31, 1996) during which any party will
be subject to a nonfinal order, decree, ruling or action restraining, enjoining
or otherwise prohibiting the consummation of the Merger or the calling or
holding of the Special Meeting; or (iii) if any governmental entity shall have
issued an order, decree or ruling or taken any other action permanently
enjoining, restraining or otherwise prohibiting the Merger and such order,
decree, ruling or other action will have become final and nonappealable; (c) by
Axion if BMS or BMS Sub shall have failed to comply in any material respect with
any of the covenants or agreements contained in the Merger Agreement or any of
the other Documents (as defined herein) to be performed by BMS or BMS Sub at or
prior to the time of termination, which breach will not have been cured within
30 days following written notice of such breach; or (d) by BMS if Axion or any
of its subsidiaries shall have failed to comply in any material respect with any
of the covenants or agreements contained in the Merger Agreement or any Document
to be performed by Axion or any of its subsidiaries at or prior to the time of
termination, which breach shall not have been cured within 30 days following
written notice of such breach.

   
     Expenses. The Merger Agreement provides that (except as provided below)
whether or not the Merger is consummated, all out-of-pocket fees and expenses
incurred in connection with the Merger, the Distribution or the consummation of
any of the transactions contemplated by the Merger Agreement and the Documents
and the negotiation, preparation, review and delivery of the agreements
contemplated thereby, including all fees and expenses of accountants, legal
counsel, investment bankers and other advisors will be paid by the party
incurring such fees or expenses, except that expenses incurred in connection
with printing and mailing this Proxy Statement/Prospectus and the Form S-4 will
be shared equally by BMS and Axion. Expenses incurred in connection with the
Required AHC Documents (as defined herein) will be paid by Axion. At the
Closing, BMS will provide, or cause to be provided, to Axion funds in an amount
equal to the lesser of $2,000,000 and the aggregate amount of Axion Expenses (as
defined herein) set forth in a true and complete schedule to be submitted by
Axion to BMS not later than five business days prior to Closing, and Axion will
pay the Axion Expenses listed in such schedule.
    

     Accounting Treatment. The Merger will be accounted for by BMS as a
"purchase" for financial accounting purposes in accordance with generally
accepted accounting principles ("GAAP"), whereby the purchase price will be
allocated based on the fair values of assets acquired and liabilities assumed.
See "The Merger--Accounting Treatment".
   

     The Distribution Agreement

     The Distribution Agreement provides for a series of asset and stock
transfers and liability assumptions, including the Contributions, between and
among Axion, AHC and certain of Axion's subsidiaries prior to the Distribution.
Such asset and stock transfers and liability assumptions, including the
Contributions, are designed to separate the Acquired Business, which is not
being acquired by BMS in the Merger, from the Retained Business prior to the
Time of Distribution. Accordingly, the Retained Business will constitute all the
business, assets and liabilities of Axion at the Effective Time. The purpose of
this complex structure is to permit the disposition of the Retained Business in
a transaction that should be tax free to Axion stockholders in which Axion
stockholders will receive BMS Common Stock and will also retain their
proportionate equity interests in the Acquired Business in the form of AHC
Preferred Stock to be received in the Distribution. In the event Axion
stockholders do not approve the

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

   
Merger, or if the Merger Agreement is otherwise terminated, Axion nonetheless
intends to consummate the Contributions. See "Risk Factors--Certain Federal
Income Tax Consequences" and "Certain Federal Income Tax Consequences" and "The
Distribution".

     The Distribution will be effected by the distribution to each holder of
record of Axion Common Stock, as of the close of the stock transfer books on the
record date for the Distribution (the "Distribution Record Date"), of
certificates representing one share of AHC Preferred Stock for each share of
outstanding Axion Common Stock held of record by such holder and by the
distribution to each holder of Axion Preferred Stock, as of the Distribution
Record Date, of certificates representing one share of AHC Preferred Stock for
each share of Axion Preferred Stock held of record by such holder. See "The
Distribution--Terms of the Distribution Agreement".

     Although the Distribution will not be effected unless the Merger is
approved and about to occur, the Distribution is separate from the Merger, and
the AHC Preferred Stock to be received by holders of Axion Common Stock and
holders of Axion Preferred Stock in the Distribution does not constitute a part
of the consideration to be received by Axion stockholders in the Merger. Axion
stockholders are not being asked to approve the Distribution, which is not
subject to stockholder approval. Axion stockholders should review the
Information Statement attached as Appendix G hereto for additional information
with respect to the Distribution, the Acquired Business and the AHC Preferred
Stock. Consummation of the Distribution is a condition to the Merger.

     BMS, Axion, BMS Sub, AHC and certain other parties will enter into certain
agreements, as applicable, designed to effectuate the separation of the Acquired
Business from the Retained Business and to facilitate the operation of AHC as a
separate entity. Each of the Former Axion Stockholders will also become a party
to certain of those agreements. See "The Distribution".

     The Indemnification Agreement

     AHC, the 81% AHC Subsidiaries (as defined herein) (including OPUS Sub), the
Former Axion Stockholders, BMS, the Surviving Corporation, OPUS, OTNC and the
Partnership will enter into a Post-Closing Covenants and Indemnification
Agreement, the form of which is attached as Appendix C to this Proxy
Statement/Prospectus and is incorporated herein by reference (as it may be
amended, supplemented or otherwise modified from time to time, the
"Indemnification Agreement"), pursuant to which AHC, the 81% AHC Subsidiaries
(including OPUS Sub) and each Former Axion Stockholder (collectively, the "AHC
Indemnifying Parties") will indemnify BMS, the Surviving Corporation, OTNC,
OPUS, the Partnership and their respective subsidiaries and affiliates against
certain Indemnifiable Losses (as defined herein) relating to or arising from any
breach of any representation, warranty or covenant of Axion or any of its
subsidiaries in any Document; any material misstatements or omissions contained
in this Proxy Statement/Prospectus, the Information Statement or any Required
AHC Document (as defined herein) with respect to information related to Axion
and its subsidiaries (including OTN); the Acquired Assets, the Assumed
Liabilities and the Acquired Business and the business of AHC and OPUS Sub
(other than Retained Liabilities); the business of Axion and its subsidiaries
(including OTN) prior to the Merger (other than Retained Liabilities); claims of
stockholders and certain other persons to the extent relating to or arising from
the execution by Axion or any of its subsidiaries (including OTN) of any of the
Documents or the consummation of the transactions contemplated thereby
(including claims for indemnification by any officer or director of Axion or any
of its subsidiaries (including OTN)); Excess Axion Expenses (as defined herein);
any breach of terms, covenants or conditions, gross negligence or wilful
misconduct and certain liabilities related to the existing contractual
arrangements between BMS, on the one hand, and OTNC and the Partnership, on the
other hand; but excluding Indemnifiable Losses relating to tax liabilities,
which are the subject of the Tax Matters Agreement (as defined below). The
indemnification obligations of the Former Axion Stockholders will be secured by
the Escrowed Shares, and the indemnification obligations of AHC and its
subsidiaries will be secured by the Escrowed Cash, on the terms and conditions
set forth in the Escrow

Agreement described below. The indemnification obligations of each of the Former
Axion Stockholders under the Indemnification Agreement will be limited in amount
to the Escrowed Shares, except in certain circumstances involving fraud,
intentional misrepresentation or intentional breach of a covenant by any such
Former Axion Stockholder. The indemnification obligations of AHC and the 81% AHC
Subsidiaries will not be limited in amount to the Escrowed Cash. In addition,
AHC and each of the 81% AHC Subsidiaries has agreed for a period of six years
following the Closing Date (subject to extension in certain circumstances) to
certain restrictive covenants, including prohibitions on liquidation, payment of
dividends or other distributions (including by redemption or repurchase) with
respect to any of its capital stock and transactions with affiliates (including
OnCare) on a non-arms' length basis and restrictions related to mergers or sales
of all or substantially all their assets. These prohibitions and restrictions
are intended to prevent AHC and the 81% AHC Subsidiaries from engaging in
transactions that might have the effect of limiting the availability of assets
of AHC and the 81% AHC Subsidiaries to satisfy their indemnification obligations
under the Indemnification Agreement and the Tax Matters Agreement to the BMS
Indemnified Parties. BMS and its subsidiaries will also indemnify AHC and its
subsidiaries with respect to certain matters.

     Indemnification liabilities for losses arising from or related to any
breach of any representation, warranty or covenant by Axion or any of its
subsidiaries (including OTN) in any Document or any losses directly related to
OTN or the OPUS Station Business are subject to a $500,000 threshold and a
$12,000,000 cap. Indemnification liabilities for losses relating to or arising
out of breaches of any representation, warranty or covenant that is directly
related to OTN are limited to 50% of the amount of such losses. All other
indemnification obligations are not subject to a threshold and are unlimited in
amount. Indemnification obligations for losses related to or arising from any
breach of representation or warranty of Axion or any of its subsidiaries
(including OTN) in any of the Documents terminate on March 31, 1998 (or in
certain limited circumstances, on the third anniversary of the Closing Date).
All other indemnification obligations survive in perpetuity. None of the
foregoing limitations will apply in certain circumstances involving fraud or any
misrepresentation or breach of which Axion, AHC or any 81% AHC Subsidiary or
their respective officers or directors had knowledge or any intentional breach
of any covenant by any such person.

     See "Risk Factors--Indemnification Obligations of the Former Axion
Stockholders, AHC and the 81% AHC Subsidiaries" and "Indemnification
Arrangements--Terms of the Indemnification Agreement", "--Terms of the Tax
Matters Agreement" and "--Terms of the Escrow Agreement", "Relationship with
BMS--Indemnification Agreement; Escrow Agreement; Tax Matters Agreement".

     The Tax Matters Agreement

     BMS, the Surviving Corporation, the 81% AHC Subsidiaries (including OPUS
Sub) and AHC, on its own behalf and as representative of the 81% AHC
Subsidiaries and each of the Former Axion Stockholders, will enter into a Tax
Matters Agreement, the form of which is attached as Appendix D to this Proxy
Statement/Prospectus and is incorporated herein by reference (as it may be
amended, supplemented or otherwise modified from time to time, the "Tax Matters
Agreement") which sets forth each party's rights and obligations with respect to
certain tax payments, tax refunds and control of contests relating to tax
matters and also provides for (i) AHC, the 81% AHC Subsidiaries and each of the
Former Axion Stockholders to indemnify BMS, the Surviving Corporation, OTNC,
OPUS, the Partnership and their respective subsidiaries and affiliates from
certain tax liabilities (including certain tax liabilities that will arise from
the Distribution and other tax liabilities that will arise if and to the extent
that the Contributions, the Distribution and related transactions generate
additional taxable income) and (ii) BMS, the Surviving Corporation, OPUS, OTNC,
and the Partnership to indemnify AHC, OPUS Sub and each of their respective
subsidiaries and affiliates from certain other tax liabilities. The
indemnification obligations of the Former

Axion Stockholders will be secured by the Escrowed Shares, and the
indemnification obligations of AHC and its subsidiaries will be secured by the
Escrowed Cash, on the terms and conditions set forth in the Escrow Agreement
described below. The indemnification obligations of each of the Former Axion
Stockholders will be limited to the Escrowed Shares, except in certain
circumstances involving fraud, intentional misrepresentation or intentional
breach of a covenant by any such Former Axion Stockholder. The indemnification
obligations of AHC and the 81% AHC Subsidiaries will not be limited in amount to
the Escrowed Cash. In addition, AHC and each of the 81% AHC Subsidiaries has
agreed for a period of six years following the Closing Date (subject to
extension in certain circumstances) to certain restrictive covenants, including
prohibitions on liquidation, payment of dividends or other distributions
(including by redemption or repurchase) with respect to any of its capital stock
and transactions with affiliates (including OnCare) on a non-arms' length basis
and restrictions related to mergers or sales of all or substantially all their
assets. These prohibitions and restrictions are intended to prevent AHC and the
81% AHC Subsidiaries from engaging in transactions that might have the effect of
limiting the availability of assets of AHC and the 81% AHC Subsidiaries to
satisfy their indemnification obligations under the Indemnification Agreement
and the Tax Matters Agreement to the BMS Indemnified Parties. See "Risk
Factors--Indemnification Obligations of the Former Axion Stockholders, AHC and
the 81% AHC Subsidiaries" and "--Certain Federal Income Tax Consequences",
"Indemnification Arrangements--Terms of the Tax Matters Agreement",
"Relationship with BMS--Indemnification Agreement; Escrow Agreement; Tax Matters
Agreement" and "Certain Federal Income Tax Consequences".

     The Escrow Agreement

     BMS, AHC, the 81% AHC Subsidiaries and the Former Axion Stockholders and an
escrow agent to be selected by BMS and Axion (the "Escrow Agent") will enter
into an Escrow Agreement, the form of which is attached hereto as Appendix E to
this Proxy Statement/Prospectus and is incorporated herein by reference (as it
may be amended, supplemented or otherwise modified from time to time, the
"Escrow Agreement") pursuant to which at the Closing the Former Axion
Stockholders will deposit the Escrowed Shares and AHC will deposit the Escrowed
Cash into escrow to secure the indemnity obligations of AHC, the 81% AHC
Subsidiaries and the Former Axion Stockholders under the Indemnification
Agreement and the Tax Matters Agreement. There can be no assurance as to whether
all or any portion of the Escrowed Shares will eventually be released to the
Former Axion Stockholders. The indemnification obligations of each of the Former
Axion Stockholders will be limited to the Escrowed Shares, except in certain
circumstances involving fraud, intentional misrepresentation or intentional
breach of a covenant by any such Former Axion Stockholder, and will terminate
one year after the Closing Date, subject to a holdback of Escrowed Shares for
any then Pending Claims (as defined herein). To the extent not previously paid
to BMS in respect of an indemnification loss, up to $4,000,000 of the Escrowed
Cash may be released to AHC on the second anniversary of the Closing Date and
the balance of such Escrowed Cash may be released to AHC on the sixth
anniversary of the Closing Date, in each case subject to a holdback for any then
Pending Claims. AHC and the 81% AHC Subsidiaries' indemnification obligations
are not limited to the Escrowed Cash. There can be no assurance as to whether
all or any portion of such Escrowed Cash will eventually be released to AHC or
that the indemnification obligations of AHC and the 81% AHC Subsidiaries will
not exceed the amount of the Escrowed Cash. Failure to obtain the release of
such Escrowed Cash or the incurrence of indemnification obligations in excess of
the Escrowed Cash (which AHC and the 81% AHC Subsidiaries may not have the
resources to pay) could have a material adverse effect on AHC's business,
financial condition or results of operations and, accordingly, the value of the
AHC Preferred Stock. There also can be no assurance that AHC and the 81% AHC
Subsidiaries will have sufficient resources or liquidity to meet their
indemnification obligations and, accordingly, there can be no assurance that the
value of the AHC Preferred Stock will not be materially adversely affected. See
"Risk Factors--Indemnification Obligations of the Former Axion Stockholders, AHC
and the 81% AHC Subsidiaries", "--Business of AHC after the Closing" and

Recommendation of the Axion Board

   
     The Axion Board believes that the terms of the Merger are fair to, and in
the best interests of, Axion and the Axion stockholders. Accordingly, the Axion
Board has unanimously approved the Merger Agreement and the transactions
contemplated thereby, including the Merger, and unanimously recommends that the
stockholders of Axion vote FOR the adoption and approval of the Merger Proposal
and that the holders of Axion Preferred Stock vote FOR approval of the Preferred
Stock Proposal. See "The Merger--Background and Reasons for the Merger;
Recommendation of the Axion Board".
    

The Special Meeting

     Time, Place and Date

   
     The Special Meeting will be held on October 18, 1996, at 8:00 a.m., local
time, at the offices of Gunderson Dettmer Stough Villeneuve Franklin &
Hachigian, LLP, legal counsel to Axion, located at 600 Hansen Way, Second Floor,
Palo Alto, California 94304.
    

     Purpose of Special Meeting; Stockholders Entitled to Vote; Vote Required

   
     At the Special Meeting, (i) stockholders of Axion of record as of the
Record Date will be asked to consider and vote upon the Merger Proposal and (ii)
holders of Axion Preferred Stock of record as of the Record Date will be asked
to consider and vote upon the Preferred Stock Proposal. Approval of the Merger
Proposal requires the affirmative vote of (i) at least a majority of the total
number of votes entitled to be cast by holders of Axion Common Stock and holders
of Axion Preferred Stock, voting together as a single class (with each share of
Axion Preferred Stock having voting power equivalent to one share of Axion
Common Stock) and (ii) at least a majority of the total number of votes entitled
to be cast by holders of Axion Preferred Stock, voting together as a single
class. Approval of the Preferred Stock Proposal requires the affirmative vote of
at least 66-2/3% of the total number of votes entitled to be cast by holders of
Axion Preferred Stock, voting together as a single class. It is a condition to
the respective obligations of each party to the Merger Agreement that the
Preferred Stock Proposal be approved. If the Merger is not consummated, the
Preferred Stock Conversion will not be implemented.

     As of the Record Date, the total number of votes entitled to be cast by
holders of Axion Common Stock was 1,606,651, the total number of votes entitled
to be cast by holders of Axion Common Stock and Axion Preferred Stock, voting as
a single class (with each share of Axion Preferred Stock having voting power
equivalent to that of one share of Axion Common Stock) was 8,347,541 and the
total number of votes entitled to be cast by holders of Axion Preferred Stock,
voting as a single class, was 6,740,890. As of the Record Date, directors and
executive officers of Axion and their affiliates beneficially owned an aggregate
of 1,154,000 shares of Axion Common Stock, or approximately 71.8% of the shares
of Axion Common Stock outstanding on such date. As of the Record Date, directors
and executive officers of Axion and their affiliates beneficially owned an
aggregate of 4,682,322 shares of Axion Preferred Stock, or approximately 69.4%
of the shares of Axion Preferred Stock outstanding on such date. As of the
Record Date, directors and executive officers of Axion and their affiliates
beneficially owned shares of Axion Common Stock or Axion Preferred Stock
representing an aggregate of 69.9% of the total number of votes entitled to be
cast by all stockholders of Axion, voting as a single class. See "The Special
Meeting--Vote Required".

Stockholder Agreement

   
     Certain stockholders of Axion which were the beneficial owners, as of the
Record Date, of 1,154,000 shares of Axion Common Stock and 5,741,839 shares of
Axion Preferred Stock have entered into the Stockholder Agreement dated as of
August 2, 1996 (as it may be amended, supplemented or otherwise modified from
time to time, the "Stockholder Agreement") with BMS and BMS Sub. Pursuant to the
Stockholder Agreement, each such stockholder agreed to vote all shares of Axion
Common Stock and/or Axion Preferred Stock beneficially owned or subsequently
acquired by such stockholder in favor of the Merger Proposal and the Preferred
Stock Proposal, and granted BMS an irrevocable proxy to so vote such shares.
Such shares represent 82.6% of the total number of votes entitled to be cast by
holders of Axion Common Stock and Axion Preferred Stock, voting together as a
single class, and 85.2% of the total number of votes entitled to be cast by
holders of Axion Preferred Stock, voting together as a single class.
Accordingly, the Merger Proposal and the Preferred Stock Proposal can be
approved by the affirmative vote of such shares even if all other stockholders
of Axion vote against the Merger Proposal and the Preferred Stock Proposal. See
"The Special Meeting--Vote Required". The Stockholder Agreement also prohibits
such stockholders from transferring their shares of Axion Common Stock or Axion
Preferred Stock until the Merger is consummated or the Merger Agreement is
terminated.
    

Certain Federal Income Tax Consequences

     The Distribution

   
     Ernst & Young LLP ("Ernst & Young"), certified public accountants to Axion,
have rendered an opinion to the effect that, based upon certain representations
of BMS, BMS Sub, Axion, AHC and certain of the Former Axion Stockholders, among
other things, the Distribution should qualify as a tax-free spinoff pursuant to
Section 355 of the Internal Revenue Code of 1986, as amended (the "Code"), and,
as a result, holders of Axion Common Stock should recognize no gain or loss upon
the receipt of AHC Preferred Stock pursuant to the Distribution. Consummation of
the Distribution and the Merger is conditioned on a reaffirmation of that
opinion at the Time of Distribution by Ernst & Young. Such opinion is based on
Ernst & Young's interpretation as to how various requirements of Section 355 of
the Code should apply to the particular facts presented by the Distribution.
With respect to some of these interpretations, no direct legal precedents exist.
Accordingly, there can be no assurance that the IRS will agree with the
conclusions set forth in the Ernst & Young opinion. No rulings relating to the
Distribution have been sought or will be received from the Internal Revenue
Service (the "IRS"), and the Ernst & Young opinion is not binding on the IRS.
Moreover, no published rulings or cases squarely address the qualification under
Section 355 of the Code of a transaction identical to the Distribution. If the
IRS were to assert successfully that the Distribution did not qualify as a
tax-free spinoff under Section 355 of the Code, the Distribution would be a
taxable transaction to Axion and the Former Axion Stockholders for federal
income tax purposes. Stockholders are urged to consult their own tax advisors
regarding such tax consequences. Even if the Distribution does qualify as a
tax-free spinoff under Section 355 of the Code, the distribution of the AHC
Preferred Stock by Axion to Non-United States Holders (as defined herein) will
constitute a taxable transaction to Axion. See "Certain Federal Income Tax
Consequences".

     To the extent of the tax liabilities to Axion that will arise from the
distribution of AHC Preferred Stock to Non-United States Holders, BMS will seek
indemnification from AHC, the 81% AHC Subsidiaries and the Former Axion
Stockholders pursuant to the Tax Matters Agreement and the Escrow Agreement. In
addition, if, notwithstanding receipt of such opinion and reaffirmation from
Ernst & Young, it is determined that the Distribution does not qualify as a
tax-free spinoff under Section 355 of the Code, then BMS may seek
indemnification from AHC, the 81% AHC Subsidiaries and the Former Axion
Stockholders pursuant to the terms of the Tax Matters Agreement and the Escrow
Agreement. Such events could result in failure by the Former Axion Stockholders
to

obtain the release of any of the Escrowed Shares, could result in AHC's failure
to obtain the release of any of the Escrowed Cash and could require AHC to
provide additional funds to indemnify BMS. Failure by AHC to obtain the release
of the Escrowed Cash, or the requirement of additional payments by AHC, could
have a material adverse effect on AHC or the value of the AHC Preferred Stock.
See "Indemnification Arrangements--Terms of the Tax Matters Agreement" and
"--Terms of the Escrow Agreement". See also "Risk Factors--Indemnification
Obligations of the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries",
"--Business of AHC after the Closing" and "--Certain Federal Income Tax
Consequences".
    

     The Merger

   
     Axion has received an opinion of Gunderson Dettmer Stough Villeneuve
Franklin & Hachigian, LLP, counsel for Axion, to the effect that, based upon
certain representations of BMS, BMS Sub, Axion and certain of the Former Axion
Stockholders, among other things, the Merger will constitute a reorganization
within the meaning of Section 368(a) of the Code. Provided the Merger does so
qualify, holders of Axion Common Stock will recognize no gain or loss upon the
conversion of shares of Axion Common Stock into shares of BMS Common Stock,
except for gain or loss recognized on receipt of cash in lieu of any fractional
share interest in BMS Common Stock. No rulings relating to the Merger have been
sought or will be received from the IRS, and such opinion is not binding on the
IRS. If the IRS were to assert successfully that the Merger did not qualify for
tax-free treatment, the receipt of BMS Common Stock in the Merger would be a
taxable transaction for federal income tax purposes and the Distribution would
not qualify as a tax-free spinoff. Stockholders are urged to consult their own
tax advisors regarding such tax consequences. See "Certain Federal Income Tax
Consequences".
    

Interests of Certain Persons in the Transactions

   
     In considering the recommendation of the Axion Board, Axion stockholders
should be aware that certain members of Axion's management and the Axion Board
have certain interests in the Merger and the Distribution that are in addition
to the interests of Axion stockholders generally. These interests include the
following consequences under the Axion 1989 Plan (as defined herein) and the
Axion 1995 Plan (as defined herein) and pursuant to the Merger Agreement with
respect to Axion Options: (i) all Axion Options that had not previously become
exercisable and vested will become fully exercisable and vested in connection
with the Merger; (ii) Axion will extend Employee Loans (as defined below) to
each executive officer, in addition to each current employee or consultant, to
enable such individual to exercise in full his or her Axion Options; and (iii)
each officer, employee or consultant who exercises his or her Axion Options will
receive in the Merger shares of BMS Common Stock, which stock will be freely
tradable immediately following the consummation of the Merger, subject to
contractual restrictions on the officer's ability to resell the BMS Common Stock
and the limitations set forth under Rule 145 under the Securities Act. As of the
Record Date, options to purchase a total of 1,697,968 shares of Axion Common
Stock, at exercise prices ranging from $0.075 to $10.00 per share, were held by
91 Axion employees and consultants. It is anticipated that Axion will make loans
totaling approximately $6,500,000 (the "Employee Loans") to such holders of
Axion Options, who will use such proceeds to exercise Axion Options immediately
prior to the Time of Contribution. Michael D. Goldberg, the President and Chief
Executive Officer and a director of Axion, has advised Axion that he does not
intend to exercise the Goldberg $10.00 Options.

     In addition, OTNC has entered into an employment agreement with David
Levison dated as of August 2, 1996, which agreement becomes effective on the
Closing Date and continues for a period of two years. Pursuant to this
agreement, David Levison will serve as President of OTNC. OTNC has entered into
employment agreements substantially similar to David Levison's (other than
compensation amounts) with Warren Dodge, Bret Brodowy, Michael Cunningham, Lynn
Hammerschmidt and James Adams.

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

   
     Axion has entered into separate indemnification agreements with its
directors and officers. These agreements require Axion, among other things, to
indemnify its directors and officers against certain liabilities that arise by
reason of their status or service as directors or officers (other than
liabilities arising from actions not taken in good faith or in a manner the
indemnitee believed to be in the best interests of Axion) and to advance their
expenses incurred as a result of any proceeding against them as to which they
could be indemnified. See "The Merger--Interests of Certain Persons in the
Transactions" and "Effect of Transactions on Axion Employees and Axion Benefit
Plans". The Axion Certificate of Incorporation also provides for exculpation of
directors under certain circumstances. See "Comparison of Certain Rights of
Holders of BMS Common Stock, Holders of Axion Common Stock--Indemnification of
Officers and Directors and Holders of Axion Preferred Stock". In addition, it is
anticipated that AHC will enter into similar indemnification agreements with its
directors and officers, and that the AHC certificate of incorporation and
by-laws will provide, as applicable, for the indemnification of directors and
officers and the exculpation under certain circumstances of directors. See
"Executive Compensation Plans in Effect After the Distribution--AHC
Indemnification Agreements" in the Information Statement attached as Appendix G
hereto.
    

Relationship with BMS

     Following the Merger, AHC and its subsidiaries will continue to have
certain relationships with BMS.

   
     AHC, the 81% AHC Subsidiaries (including OPUS Sub), the Former Axion
Stockholders, BMS, the Surviving Corporation, OPUS, OTNC and the Partnership
will be parties to the Indemnification Agreement, the Tax Matters Agreement and
the Escrow Agreement. See "Indemnification Arrangements--Terms of the
Indemnification Agreement"; "--Terms of the Tax Matters Agreement"; and "--Terms
of the Escrow Agreement".

     BMS has entered into separate Noncompetition Agreements with AHC and OnCare
and each of Michael D. Goldberg, the President and Chief Executive Officer and a
director of Axion, OnCare and AHC, and Garrett J. Roper, the Senior Vice
President and Chief Financial Officer of Axion, OnCare and AHC and the Secretary
and a director of AHC (the "Noncompetition Agreements") which will become
effective at Closing and will, for two years following the Closing Date,
prohibit such entities or persons and their affiliates, as the case may be,
from, as applicable, ownership, management, operation or control of, employment
by, holding certain equity interests in or serving as a director, advisor or
consultant to, or having certain other relationships with, any entity that
engages in the distribution of oncology drugs, supplies or biologics to certain
customers of OTN or the automated drug dispensing and inventory tracking systems
business in the United States. See "Relationship with BMS--Noncompetition
Agreements".

     AHC has entered into the AHC Supply Agreement (the "AHC Supply Agreement")
with OTN and OnCare has entered into the OnCare Supply Agreement (the "OnCare
Supply Agreement") with OTN which will become effective at the Closing and which
provide that AHC and OnCare will use OTN as their exclusive provider of oncology
pharmaceutical products and supplies and that OTN will provide such products and
supplies at the lowest price it offers to a specified category of purchaser
(subject to certain conditions), provided that in the event AHC or OnCare, as
the case may be, receives an offer pricing products or supplies at a price of at
least 10% less than the lowest price offered by OTN and OTN chooses not to match
such lower offer, AHC or OnCare, as the case may be, may purchase such products
or supplies pursuant to such lower offer for a term to end upon the later of 30
days after the receipt of such lower offer and the term of such lower offer.
OTN's existing supply agreement with OnCare will be terminated on the Closing
Date. AHC has entered into the AHC Medstation Agreement (the "AHC Medstation
Agreement") and OnCare has entered into the OnCare Medstation Agreement (the
"OnCare Medstation Agreement") which will become effective at the Closing and
which provide that AHC and OnCare will use OPUS as their exclusive provider of
oncology drug dispensing machines and that OPUS will provide such

machines at the lowest price it offers to a specified category of purchaser
(subject to certain conditions). See "Relationship with BMS--AHC Supply
Agreement; OnCare Supply Agreement; AHC Medstation Agreement; OnCare Medstation
Agreement".

     AHC and the Surviving Corporation will enter into a Trademark License
Agreement (the "License Agreement") pursuant to which AHC will grant an
exclusive, royalty-free license to the Surviving Corporation to use the "OPUS"
name in connection with the OPUS Station Business in the U.S. for a period of
one year. AHC and the Surviving Corporation will also enter into a Transitional
Services Agreement (the "Transitional Services Agreement") pursuant to which AHC
and the Surviving Corporation will provide certain services to each other
following the Merger. See "Relationship with BMS--License Agreement" and
"--Transitional Services Agreement".
    

Dissenters' Rights

   
     Each holder of Axion Common Stock who (i) delivers to Axion a written
demand for appraisal to receive payment of the "fair value" of his or her shares
prior to the Special Meeting and (ii) votes against approval of the Merger
Agreement or who abstains from such vote is entitled to the rights and remedies
of dissenting stockholders upon complying with the procedures set forth in
Section 262 ("Section 262") of the Delaware General Corporate Law (the "DGCL"),
a copy of which is attached as Appendix F hereto. A vote against approval of the
Merger Agreement or abstention from such vote, by itself, will not constitute a
demand for appraisal within the meaning of Section 262. It is a condition to the
obligations of BMS to effect the Merger that no Dissenting Shares be outstanding
at the Effective Time. See "Risk Factors--Vote Required; Stockholder Agreement"
and "The Merger--Dissenters' Rights".
    

Certain Regulatory Approvals

   
     The consummation of the Merger is subject to, among other approvals, the
expiration or termination of the relevant waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). Axion and BMS each filed notification and report forms under the HSR Act
with the Federal Trade Commission (the "FTC") and the Antitrust Division of the
Justice Department (the "Antitrust Division") on July 10, 1996. The waiting
period expired on August 9, 1996, without further action by the FTC or the
Antitrust Division.
See "The Merger--Certain Regulatory Approvals".

Comparison of Certain Rights of Holders of BMS Common Stock, Holders of Axion
Common Stock and Holders of Axion Preferred Stock

     See "Comparison of Certain Rights of Holders of BMS Common Stock, Holders
of Axion Common Stock and Holders of Axion Preferred Stock" for a summary of
certain significant differences among the rights of holders of BMS Common Stock,
the rights of holders of Axion Common Stock and the rights of holders of Axion
Preferred Stock. See "Comparison of Certain Rights of Holders of Common Stock"
in the Information Statement attached as Appendix G hereto for a summary of
certain significant differences among the rights of holders of AHC Preferred
Stock, the rights of holders of Axion Common Stock and the rights of holders of
Axion Preferred Stock.
    

Risk Factors

     In deciding whether to approve and adopt the Merger Proposal, and, as
applicable, the Preferred Stock Proposal, stockholders should carefully evaluate
the matters set forth under "Risk Factors" herein and under "Special Factors" in
the Information Statement attached as Appendix G hereto, in addition to other
matters described herein and therein.

dividends. See "Comparison of Certain Rights of Holders of BMS Common Stock,
Holders of Axion Common Stock and Holders of Axion Preferred Stock--Dividends".

                           Comparative Per Share Data

   
     The following table sets forth certain per share historical financial
information for BMS, Axion and the Retained Business, certain pro forma per
share information for the Retained Business giving effect to the Merger and the
transfer from Axion to AHC of the OnCare Preferred Stock, the Employee Loans and
cash and cash equivalents and short-term investments (other than Retained Cash,
which is assumed to equal zero) totaling approximately $16,100,000 at June 30,
1996, and equivalent pro forma per share information of Axion based on the
conversion of each share of Axion Common Stock (calculated on a fully diluted
basis reflecting the Diluted Share Assumption) into BMS Common Stock based on an
assumed Conversion Number of 0.094. See "The Merger--Terms of the Merger
Agreement". Pro forma financial statements for BMS giving effect to the Merger
are not included in this Proxy Statement/Prospectus because the Merger will not
have a material effect on BMS and, accordingly, pro forma per share information
for BMS giving effect to the Merger has not been included below.

     The following information is based upon and should be read in conjunction
with and is qualified in its entirety by the respective audited and unaudited
financial statements of BMS, Axion and the Retained Business incorporated by
reference or included elsewhere in this Proxy Statement/Prospectus and the Pro
Forma Condensed Financial Statements of Axion and Axion HealthCare Inc. and the
notes thereto presented elsewhere herein. See "Incorporation of Certain

(c)  Assuming conversion of all shares of Axion Preferred Stock as set forth
     above in note (b). Historical book value of the Retained Business at June
     30, 1996, based on 1,606,651 shares of Axion Common Stock outstanding at

     Financial Statements of Axion Inc. for a description of the shares used in
     the calculation of net income per common share.

(d)  Assuming conversion of all outstanding shares of Axion Preferred Stock as
     set forth above in note (b). Assumes no exercise of Axion Options. After
     giving effect to assumed exercise of all Axion Options outstanding at June
     30, 1996 (other than the Goldberg $10.00 Options) to purchase 1,630,215
     shares of Axion Common Stock, Retained Business pro forma book value per
     common share is $(.27). See Note 1 (Per Share Data) to the Notes to
     Consolidated Financial Statements of Axion Inc. for a description of the
     shares used in the calculation of net income per common share.

(e)  Reflects the pro forma equivalent of one share of Axion Common Stock
     (excluding AHC Preferred Stock to be received by Axion stockholders in the
     Distribution), calculated by multiplying BMS historical per share data by
     an assumed Conversion Number of 0.094 (assuming an Average Value of BMS
     Common Stock equal to the Maximum Price, based on the actual number of
     shares of Axion Common Stock outstanding as of the Record Date and assuming
     the conversion of all shares of Axion Preferred Stock and the exercise of
     all Axion Options (other than the Goldberg $10.00 Options)). The actual
     Conversion Number will depend on the Average Value of BMS Common Stock on
     the Closing Date and the number of shares of Axion Common Stock outstanding
     immediately prior to the Effective Time, and may be greater or less than
     0.094. See "Risk Factors--Risk of Decline in Average Value of BMS Common
     Stock Prior to the Effective Time" and "The Merger--Terms of the Merger
     Agreement".

- ----------
(a) Net income (loss) per share has been computed based on the weighted average
shares of Axion Common Stock outstanding and dilutive common equivalent shares
outstanding. Common equivalent shares represent shares of Axion Preferred Stock
outstanding (using the if converted method) and Axion Options outstanding (using
the treasury stock method). In 1991, 1992 and 1993, all common equivalent shares
were excluded from the per share computation due to their antidilutive effect as
a result of the net losses for such years. After 1993, common equivalent shares
have been included in the per share computation.

Retained Business

   
     The following table sets forth selected historical financial data with
respect to the Retained Business for the periods and at the dates indicated. The
financial data of the Retained Business at and for the year ended December 31,
1995 are derived from the notes to the audited financial statements of Axion for
that year, and the financial data of the Retained Business at June 30, 1996 and
for the six-month periods ended June 30, 1995 and 1996 are derived from the
notes to the unaudited financial statements of Axion for those periods. The
following selected historical financial data of the Retained Business for the
four years ended December 31, 1994 are derived from the audited financial
statements of Axion. Prior to 1995, separate financial statements were not

necessarily indicative of the results that may be expected for the entire year

included herein.

     Pro Forma Balance Sheet Data

   
     The following unaudited pro forma balance sheet data of the Retained
Business at June 30, 1996 (dollars in thousands) give effect to the Merger and
to the Distribution, after the transfer from Axion to AHC of: (i) the cash
distribution from the Partnership to Axion of the Preference Amount of $13,615
(which would have required additional borrowings by the Partnership of $17,915
at June 30, 1996, which would have been used to fund the $13,615 payment and a
$5,000 reduction of borrowings under the bank line of credit) and $2,485 of
additional cash and cash equivalents and short-term investments, subject to
adjustment, (ii) the Employee Loans and (iii) $13,500 redemption and carrying
value of 2,700,000 shares of OnCare Preferred Stock. The pro forma data are
presented for illustrative purposes only, and are not necessarily indicative of
the results that actually would have been obtained had all the transactions
referred to above been completed as of the assumed date, and are not intended to
be a projection of future results or trends.

Current assets                                                        $ 139,184
Total assets                                                            140,182
Payable to BMS-Sales Agency Agreement                                    55,429
Borrowings under bank line of credit                                     35,616
Additional borrowings                                                    17,915
Stockholders' equity (net capital deficiency)                            (2,715)

     No pro forma statements of operations data of the Retained Business are
shown because the pro forma adjustments referred to above would have no
statements of operations impact for the six-month period ended June 30, 1996,
other than loss of $894 income tax benefit.

BMS

   
     The selected historical consolidated financial data of BMS set forth in the
table below have been derived from the audited financial statements of BMS for
each of the five fiscal years through the period ended December 31, 1995 and the
unaudited financial statements of BMS for the six-month periods ended June 30,
1996 and 1995. The selected historical consolidated financial data set forth
below should be read in conjunction with the historical consolidated financial
statements and the notes thereto contained in BMS's Annual Report on Form 10-K
for the year ended December 31, 1995 and BMS's Quarterly Report on Form 10-Q for
the six months ended June 30, 1996, which are incorporated by reference herein.
In BMS's opinion, all adjustments, consisting only of normal recurring
adjustments, necessary for the fair presentation of the financial position and
results of operations for such six-month periods have been made. The results of
operations for the six-month period ended June 30, 1996 are not necessarily
indicative of the results to be expected for the full year 1996. See
"Incorporation of Certain Information by Reference" and "Available Information".
Pro forma financial statements for BMS giving effect to the Merger are not
included in this Proxy Statement/Prospectus because the Merger will not have a
material effect on BMS.

                                  RISK FACTORS

   
     In deciding whether to approve and adopt the Merger Proposal and, if
applicable, the Preferred Stock Proposal, stockholders should carefully evaluate
the following matters, in addition to the matters set forth under "Special
Factors" in the Information Statement attached hereto as Appendix G and other
matters described in this Proxy Statement/Prospectus and in the Information
Statement.

Indemnification Obligations of the Former Axion Stockholders, AHC and the 81%
AHC Subsidiaries

     AHC, the 81% AHC Subsidiaries (including OPUS Sub) and each Former Axion
Stockholder will become a party to the Indemnification Agreement, the Tax
Matters Agreement and the Escrow Agreement. Pursuant to these agreements, AHC,
the 81% AHC Subsidiaries and the Former Axion Stockholders will agree to
indemnify the BMS Indemnified Parties (including BMS, the Surviving Corporation,
OPUS, OTNC and the Partnership) against certain liabilities, including
liabilities relating to or arising from any breach of any representation,
warranty or covenant of Axion or any of its subsidiaries (including OTN) in any
Document; any material misstatements or omissions contained in this Proxy
Statement/Prospectus, the Information Statement or any Required AHC Document
with respect to information related to Axion and its subsidiaries; the Acquired
Assets, the Assumed Liabilities and the Acquired Business and the business of
AHC and OPUS Sub (other than Retained Liabilities); the business of Axion and
its subsidiaries (including OTN) prior to the Merger (other than Retained
Liabilities); claims of stockholders and certain other persons to the extent
relating to or arising from the execution by Axion or any of its subsidiaries
(including OTN) of any of the Documents or the consummation of the transactions
contemplated thereby (including claims for indemnification by any officer or
director of Axion or any of its subsidiaries (including OTN)); Excess Axion
Expenses; any breach of terms, covenants or conditions, gross negligence or
wilful misconduct and certain liabilities related to the existing contractual
arrangements between BMS, on the one hand, and OTNC and the Partnership, on the
other hand; certain pre-closing tax liabilities of Axion and its subsidiaries
(including OTN), including certain tax liabilities that will arise from the
distribution of AHC Preferred Stock to Non-United States Holders; and any tax
liabilities that will arise if and to the extent that the Contributions, the
Distribution and related transactions generate additional taxable income.

     To secure these indemnification obligations, immediately following the
Effective Time, the Escrowed Shares, valued at $5,000,000, will be placed in
escrow and AHC will place the Escrowed Cash of $5,000,000 in escrow. In
addition, AHC and the 81% AHC Subsidiaries each have agreed for a period of six
years following the Closing Date (subject to extension in certain circumstances)
to certain restrictive covenants, including prohibitions on liquidation, payment
of dividends or other distributions (including by redemption or repurchase) with
respect to any of its capital stock and transactions with affiliates (including
OnCare) on a non-arms' length basis and restrictions related to mergers or sales
of all or substantially all their assets. These prohibitions and restrictions
are intended to prevent AHC and the 81% AHC Subsidiaries from engaging in
transactions that might have the effect of limiting the availability of assets
of AHC and the 81% AHC Subsidiaries to satisfy their indemnification obligations
under the Indemnification Agreement and the Tax Matters Agreement to the BMS
Indemnified Parties.

     Certain of the AHC Indemnifying Parties' (as defined herein)
indemnification obligations are subject to agreed limitations. Indemnification
obligations for losses arising from or related to any breach of any
representation, warranty or covenant by Axion or any of its subsidiaries
(including OTN) in any Document or any losses directly related to OTN or the
OPUS Station Business are subject to a $500,000 threshold and a $12,000,000 cap.
Indemnification obligations for losses relating to or arising out of breaches of
any representation, warranty or covenant that is directly related to OTN are
limited to 50% of the amount of such losses. All other indemnification
obligations are unlimited in amount. Indemnification obligations for losses
related to or arising from any breach of

representation or warranty of Axion or any of its subsidiaries (including OTN)
in any of the Documents terminate on March 31, 1998 (or, in certain limited
circumstances, on the third anniversary of the Closing Date). All other
indemnification obligations survive in perpetuity. None of the foregoing
limitations will apply in certain circumstances involving fraud or any
misrepresentation or breach of which Axion, AHC or any 81% AHC Subsidiary or
their respective officers or directors had knowledge or any intentional breach
of any covenant by any such person.

     The indemnification obligations of each Former Axion Stockholder will be
limited in amount to such Former Axion Stockholder's pro rata share of the
Escrowed Shares, except in certain circumstances involving fraud, intentional
misrepresentation or intentional breach of a covenant by any such Former Axion
Stockholder, and will terminate one year after the Closing Date, subject to a
holdback of Escrowed Shares for any then Pending Claims. During such period BMS
will recover indemnification from the Escrowed Shares even if Escrowed Cash is
also available in respect of an indemnifiable loss, subject to certain
exceptions. THERE CAN BE NO ASSURANCE AS TO WHETHER ALL OR ANY PORTION OF SUCH
ESCROWED SHARES WILL EVENTUALLY BE RELEASED TO FORMER AXION STOCKHOLDERS.

     To the extent not previously paid to BMS in respect of an indemnifiable
loss, up to $4,000,000 of the Escrowed Cash may be released to AHC on the second
anniversary of the Closing Date and the balance of such Escrowed Cash may be
released to AHC on the sixth anniversary of the Closing Date, in each case
subject to a holdback for any then Pending Claims. AHC and the 81% AHC
Subsidiaries' indemnification obligations are not limited to the Escrowed Cash.
THERE CAN BE NO ASSURANCE AS TO WHETHER ALL OR ANY PORTION OF SUCH ESCROWED CASH
WILL EVENTUALLY BE RELEASED TO AHC OR THAT THE INDEMNIFICATION OBLIGATIONS OF
AHC AND THE 81% AHC SUBSIDIARIES WILL NOT EXCEED THE AMOUNT OF THE ESCROWED
CASH. Failure to obtain the release of such Escrowed Cash or the incurrence of
indemnification obligations in excess of the Escrowed Cash (which AHC and the
81% AHC Subsidiaries may not have the resources to pay) could have a material
adverse effect on AHC's business, financial condition or results of operations
and, accordingly, the value of the AHC Preferred Stock. THERE ALSO CAN BE NO
ASSURANCE THAT AHC AND THE 81% AHC SUBSIDIARIES WILL HAVE SUFFICIENT RESOURCES
OR LIQUIDITY TO MEET THEIR INDEMNIFICATION OBLIGATIONS AND, ACCORDINGLY, THERE
CAN BE NO ASSURANCES THAT THE VALUE OF THE AHC PREFERRED STOCK WILL NOT BE
MATERIALLY ADVERSELY AFFECTED.

     In addition, the restrictive covenants referred to above and the existence
of potentially unlimited indemnification obligations may restrict the ability of
AHC to obtain financing or engage in certain transactions, including
acquisitions and strategic alliances. Failure to obtain financing or engage in
such transactions could have a material adverse effect on AHC's business,
financial condition or results of operation and, accordingly, the value of the
AHC Preferred Stock, independent of whether any indemnification payments are
actually made by or on behalf of AHC or the amount thereof.

     See "--Certain Federal Income Tax Consequences", "Indemnification
Arrangements--Terms of the Indemnification Agreement", "--Terms of the Tax
Matters Agreement" and "--Terms of the Escrow Agreement", "Relationship with
BMS--Indemnification Agreement; Escrow Agreement; Tax Matters Agreement" and
"Certain Federal Income Tax Consequences".
    

Business of AHC After the Closing

   
     The business, financial condition and results of operations of AHC after
the Closing and, accordingly, the value of the AHC Preferred Stock to be
received by stockholders of Axion in the Distribution could be materially
    


                                       32

adversely affected by a number of factors involving several types of risks,
including risks associated with AHC's business and liquidity; with AHC's
contingent indemnification obligations to BMS and its subsidiaries and
associated restrictive covenants limiting AHC's ability to engage in certain
transactions; with the federal income tax consequences of the Distribution and
the Merger; and with certain characteristics of the AHC Preferred Stock and the
potential trading market therefor.

     The business of AHC has not generated significant revenues or realized a
profit to date, and has operated and is expected to continue to operate at a
loss for the foreseeable future. AHC's prospects must be evaluated in light of
the risks, expenses and difficulties frequently encountered by recently formed
businesses. AHC has historically been dependent on Axion for funding, and AHC's
future development is dependent on its ability to obtain sufficient funding.
There can be no assurance that adequate funds for such development will be
available on acceptable terms, or at all. The cancer-specific managed care
business is characterized, Axion's management believes, by rapid change,
evolving standards and intense competition, and AHC's business is relatively
small and undiversified in nature. There can be no assurance that AHC will be
successful in developing and marketing its products and services, that AHC will
not experience difficulties that could delay or prevent the successful
development, introduction and marketing of such products and services, or that
AHC's new products and services and products and service enhancements will
adequately meet the requirements of the marketplace and achieve market
acceptance.

     Pursuant to the Indemnification Agreement, AHC and the 81% AHC Subsidiaries
each have agreed for a period of six years following the Closing Date (subject
to extension in certain circumstances) to certain prohibitions on liquidation,
payment of dividends or other distributions (including by redemption or
repurchase) with respect to any of its capital stock and transactions with
affiliates (including OnCare) on a non-arms' length basis and to certain
restrictions related to mergers or sales of all or substantially all their
assets. These prohibitions and restrictions were designed to prevent AHC and the
81% AHC Subsidiaries from engaging in transactions that might have the effect of
limiting the availability of assets of AHC and the 81% AHC Subsidiaries to
satisfy their indemnification obligations to the BMS Indemnified Parties and may
restrict AHC's ability to obtain financing or engage in certain transactions,
including acquisitions and strategic alliances. There can be no assurance that
such restrictions will not have a material adverse effect on the business or
financial condition of AHC or the value of the AHC Preferred Stock.

     As noted above, AHC and the 81% AHC Subsidiaries are subject to potential
indemnification obligations to BMS and its subsidiaries. The AHC Indemnifying
Parties' indemnification obligations for losses arising from or related to any
breach of any representation, warranty or covenant by Axion or any of its
subsidiaries (including OTN) in any Document or any losses directly related to
OTN or the OPUS Station Business are subject to a $500,000 threshold and a
$12,000,000 cap. Indemnification obligations for losses relating to or arising
out of breaches of any representation, warranty or covenant that is directly
related to OTN are limited to 50% of the amount of such losses. All other
indemnification obligations are unlimited in amount. Indemnification obligations
for losses related to or arising from any breach of representation or warranty
of Axion or any of its subsidiaries (including OTN) in any of the Documents
terminate on March 31, 1998 (or in certain limited circumstances, on the third
anniversary of the Closing Date). All other indemnification obligations survive
in perpetuity. None of the foregoing limitations will apply in certain
circumstances involving fraud or any misrepresentation or breach of which Axion,
AHC or any 81% AHC Subsidiary or their respective officers or directors had
knowledge or any intentional breach of any covenant by any such person. AHC and
the 81% AHC Subsidiaries' indemnification obligations are not limited to the
Escrowed Cash. There can be no assurance as to whether all or any portion of
such Escrowed Cash will eventually be released to AHC or that the
indemnification obligations of AHC and the 81% AHC Subsidiaries will not exceed
the amount of the Escrowed Cash. Failure to obtain the release of such Escrowed
Cash or the incurrence of indemnification obligations in excess of the Escrowed
Cash (which AHC and the 81% AHC Subsidiaries may not have the resources to pay)
could have a material adverse effect on AHC's business,
    


                                       33




<PAGE>

financial condition or results of operations and, accordingly, the value of the
AHC Preferred Stock. There also can be no assurance that AHC and the 81% AHC
Subsidiaries will have sufficient resources or liquidity to meet their
indemnification obligations and, accordingly, there can be no assurances that
the value of the AHC Preferred Stock will not be materially adversely affected.

     Although the Distribution is intended to be a tax-free spinoff under
Section 355 of the Code, there is no assurance that the Internal Revenue Service
(or any state or local taxing authority) will agree with such characterization.
Certain tax liabilities to Axion will arise from the distribution of AHC
Preferred Stock to NonUnited States Holders, and to the extent of such tax
liabilities, BMS and the Surviving Corporation will seek indemnification under
the Tax Matters Agreement from AHC. In addition, if the Distribution is
determined to be taxable to Axion as a result of a failure to qualify as a
tax-free spinoff under Section 355 of the Code, BMS and the Surviving
Corporation have the right under the Tax Matters Agreement to seek
indemnification from AHC. Such indemnification may exceed the amount of Escrowed
Cash then remaining (if any), in which case AHC will be required to pay such
indemnification directly.

     The Indemnification Agreement provides that for a period of six years
following the Effective Time (subject to extension in certain circumstances),
AHC may not declare any dividends on AHC's capital stock. In addition, there is
no existing trading market for AHC Preferred Stock. AHC has not sought and does
not intend to apply for listing of AHC Preferred Stock on a securities exchange
or seek approval for quotation through an automated quotation system. There can
be no assurance that any trading market will develop for AHC Preferred Stock. In
addition, the AHC certificate of incorporation will provide for various
restrictions on transfer of AHC Preferred Stock. The certificates evidencing the
AHC Preferred Stock will bear a legend referring to these restrictions on
transfer. Certain AHC officers also hold management positions in OnCare. There
can be no assurance that the responsibilities of such persons in their capacity
as officers of OnCare will not result in a conflict of interest with their
duties as AHC officers. Additional factors may also cause a potential conflict
of interest between AHC and OnCare, including the fact that AHC currently
conducts business with OnCare, AHC is a substantial stockholder in OnCare and
AHC and OnCare have a substantially overlapping stockholder base.

     Immediately following the Distribution, directors and executive officers of
AHC will, subject to certain assumptions, beneficially own shares of AHC
Preferred Stock representing over 57.2% of the voting power of AHC's then
outstanding voting securities. See "Special Factors" in the Information
Statement attached as Appendix G hereto.

Risk of Decline in Average Value of BMS Common Stock Prior to the Effective Time

     Based on the Diluted Share Assumption (and assuming exercise of all Axion
Options other than the Goldberg $10.00 Options, resulting in an aggregate of
9,970,509 shares of Axion Common Stock outstanding), and assuming an Average
Value of BMS Common Stock equal to $92.83 (the average per share closing price
of BMS Common Stock for the 10 full NYSE trading days ending September 18, 1996,
the most recent full NYSE trading day available prior to printing this Proxy
Statement/Prospectus), in which event the Conversion Number would be calculated
based on an Average Value of BMS Common Stock equal to the Maximum Price of
$91.43, (a) the Conversion Number would be 0.094 and (b) assuming a market value
of the BMS Common Stock on the date received by holders of Axion Common Stock in
the Merger of $92.83, the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger would be approximately
$87 million, or approximately $8.73 per share of Axion Common Stock. There can
be no assurance that these assumptions will be true as of the Effective Time.
    


                                       34

     The Average Value of BMS Common Stock is determined as of five full NYSE
trading days immediately preceding the Effective Time (which date may be after
the date of the Special Meeting), at which time the Average Value of BMS Common
Stock may be less than the assumed $92.83 Average Value of BMS Common Stock
referred to above and indeed may be less than the Minimum Price. If the Average
Value of BMS Common Stock at such time is between the Minimum Price ($82.73) and
the Maximum Price ($91.43), the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be $86 million, or
approximately $8.63 per share of Axion Common Stock (based on the Diluted Share
Assumption and assuming exercise of all Axion Options other than the Goldberg
$10.00 Options). If the Average Value of BMS Common Stock at such time is less
than the Minimum Price, the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be less, and may be
substantially less, than $86 million, or approximately $8.63 per share of Axion
Common Stock (based on the Diluted Share Assumption and assuming exercise of all
Axion Options other than the Goldberg $10.00 Options). The foregoing statements
in this paragraph assume that the market value of BMS Common Stock on the
Closing Date is equal to the Average Value of the BMS Common Stock used to
calculate the Conversion Number. However, the actual market value of BMS Common
Stock on the Closing Date may be substantially less than the Average Value of
BMS Common Stock used to calculate the Conversion Number. The actual aggregate
market value on the Closing Date of BMS Common Stock received by holders of
Axion Common Stock in the Merger will be equal to the number of shares of BMS
Common Stock issued in the Merger multiplied by the market value of the BMS
Common Stock on the Closing Date.

     Under the terms of the Merger Agreement, Axion does not have the right to
decline to consummate the Merger solely because either the Average Value of BMS
Common Stock used to calculate the Conversion Number is less than the Minimum
Price or because the actual market value of BMS Common Stock on the Closing Date
is less than the Average Value of BMS Common Stock used to calculate the
Conversion Number. Therefore, if the Merger Proposal is adopted and approved and
all other conditions to the Merger are satisfied (or waived by the party for
whose benefit any such condition exists) at or prior to the Effective Time,
Axion stockholders will assume the risk of a decline in the market value of BMS
Common Stock below the Minimum Price and the risk that the actual market value
of BMS Common Stock on the Closing Date is less than the Average Value of BMS
Common Stock used to calculate the Conversion Number and, accordingly, the risk
that the aggregate market value of BMS Common Stock to be received by the
holders of Axion Common Stock in the Merger will be substantially less than $86
million or approximately $8.63 per share (based on the Diluted Share Assumption
and assuming exercise of all Axion Options other than the Goldberg $10.00
Options).

     In addition, the number of assumed outstanding shares of Axion Common Stock
for the purpose of calculating the Conversion Number is determined as of
immediately prior to the Effective Time (which date may be after the date of the
Special Meeting), at which time the actual number of outstanding shares of Axion
Common Stock may be greater than the assumed 9,970,509 shares referred to above.
Each share of Axion Common Stock will be converted in the Merger into the right
to receive the Conversion Number of shares of BMS Common Stock. Any increase in
the actual number of outstanding shares of Axion Common Stock as of immediately
prior to the Effective Time would result in a corresponding decrease in the
Conversion Number and, accordingly, in the number of shares of BMS Common Stock
to be received in respect of each share of Axion Common Stock. The maximum
number of shares of Axion Common Stock that may be outstanding as of immediately
prior to the Effective Time is 10,070,509 shares.

     See "The Merger--Terms of the Merger Agreement--Conversion of Axion Common
Stock in the Merger" and "--Conditions--Conditions to Obligations of Axion".

Certain Federal Income Tax Consequences

   
     Although each party to the Documents intends to treat the Distribution as a
tax-free spinoff for purposes of Section 355 of the Code and to treat the Merger
as a tax-free reorganization for purposes of Section 368 of the Code, and
although tax opinions have been rendered by Ernst & Young (as to the tax-free
nature of the Distribution under Section 355 of the Code and the Merger) and by
Gunderson, Dettmer, Stough, Villeneuve, Franklin & Hachigian, LLP (as to the
tax-free nature of the Merger) to such effect, such opinions are not binding on
the IRS, and there is no assurance that the IRS (or any state or local taxing
authority) will agree with such opinions. Ernst & Young's opinion is based on
its interpretation as to how various requirements of Section 355 of the Code
should apply to the particular facts presented by the Distribution. With respect
to some of these interpretations, no direct legal precedents exist. Accordingly,
there can be no assurance that the IRS will agree with the conclusions set forth
in the Ernst & Young opinion. No ruling has been sought or will be received from
the IRS. Moreover, no published rulings or cases squarely address the
qualification as a tax-free spinoff under Section 355 of the Code of a
transaction identical to the Distribution. If the IRS were to assert
successfully that the Distribution did not qualify as a tax-free spinoff under
Section 355 of the Code, the receipt of AHC Preferred Stock in the Distribution
would be a taxable transaction to Axion and the Former Axion Stockholders for
federal income tax purposes. Even if the Distribution does qualify as a tax-free
spinoff under Section 355 of the Code, the distribution of the AHC Preferred
Stock by Axion to Non-United States Holders will constitute a taxable
transaction to Axion.

     If the Distribution fails to qualify as a tax-free spinoff under Section
355 of the Code, the Former Axion Stockholders will realize gain or loss on the
receipt of AHC Preferred Stock in the Distribution. Stockholders are urged to
consult their own tax advisors regarding such tax consequences. If the
Distribution is determined to be taxable to Axion as a result of a failure to
qualify as a tax-free spinoff under Section 355 of the Code, BMS and the
Surviving Corporation have the right under the Tax Matters Agreement to seek
indemnification from AHC, the Former Axion Stockholders and the other AHC
Indemnifying Parties (as defined herein). Certain tax liabilities to Axion will
arise from the distribution of AHC Preferred Stock to Non-United States Holders,
and to the extent of such tax liabilities, BMS and the Surviving Corporation
will seek indemnification under the Tax Matters Agreement from AHC, the Former
Axion Stockholders and the other AHC Indemnifying Parties. In each case, such
indemnification may exceed the amount of Escrowed Cash and Escrowed Shares then
remaining (if any), in which case AHC will be required to pay such
indemnification directly. Payment of such indemnification may materially
adversely affect AHC and, if AHC or the AHC Indemnifying Parties are unable to
pay such amounts, payment of such tax claims may materially adversely affect
Axion.

     If the Merger is determined to be taxable, the Former Axion Stockholders
will realize gain or loss on the receipt of BMS Common Stock in the Merger and
on the receipt of AHC Preferred Stock in the Distribution, and Axion will
recognize gain on the distribution of AHC Preferred Stock to Axion stockholders
(to the extent such gain has not previously been recognized by Axion in
connection with the distribution of AHC Preferred Stock to Non-United States
Holders). Certain tax liabilities will result from such gain, and to the extent
of such tax liabilities, BMS and the Surviving Corporation will seek
indemnification under the Tax Matters Agreement from AHC, the Former Axion
Stockholders and the other AHC Indemnifying Parties. In each case, such
indemnification may exceed the amount of Escrowed Cash and Escrowed Shares then
remaining (if any), in which case AHC will be required to pay such
indemnification directly. Payment of such indemnification may materially
adversely affect AHC and, if AHC or the AHC Indemnifying Parties are unable to
pay such amounts, payment of such tax claims may materially adversely affect
Axion. See "Certain Federal Income Tax Consequences".

     In connection with the tax opinions rendered with respect to certain tax
consequences of the Distribution or of the Merger, certain of the Former Axion
Stockholders have signed or will sign letters representing that they have no
plan or intention to sell or otherwise dispose of any of their holdings of (i)
Axion capital stock prior to the
    


                                       36




<PAGE>
 

<PAGE>



   
Merger, (ii) the AHC Preferred Stock received in the Distribution or (iii) the
BMS Common Stock received in the Merger (the "Continuity of Interest Letters").
In the event that a Former Axion Stockholder knowingly made a misrepresentation
in a Continuity of Interest Letter that resulted in the Merger failing to
qualify as a tax-free reorganization under Section 368 of the Code or the
Distribution failing to qualify as a tax-free spinoff under Section 355 of the
Code, such stockholder would be individually liable for all tax liability
resulting therefrom (which could include the failure of the Distribution and/or
the Merger to be tax-free to the extent described herein). See "Certain Federal
Income Tax Consequences".
    

Vote Required; Stockholder Agreement

   
     Certain stockholders of Axion which were the beneficial owners, as of the
Record Date, of shares representing 82.6% of the total number of votes entitled
to be cast by holders of Axion Common Stock and Axion Preferred Stock, voting
together as a single class, and 85.2% of the total number of votes entitled to
be cast by holders of Axion Preferred Stock, have entered into the Stockholder
Agreement with BMS and BMS Sub. Pursuant to the Stockholder Agreement, each such
stockholder agreed to vote all of such shares in favor of the Merger Proposal
and the Preferred Stock Proposal, and in each case granted BMS an irrevocable
proxy to so vote such shares. Accordingly, the Merger Proposal and the Preferred
Stock Proposal can be approved by the affirmative vote of such shares even if
all other stockholders of Axion vote against the Merger Proposal and the
Preferred Stock Proposal. The Stockholder Agreement also prohibits such
stockholders from transferring their shares of Axion Common Stock or Axion
Preferred Stock until the Merger is consummated or the Merger Agreement is
terminated. It is therefore expected that the Merger Proposal and the Preferred
Stock Proposal will be approved regardless of the vote of other Axion
stockholders.

     In addition, it is a condition to the obligation of BMS to effect the
Merger that no Dissenting Shares be outstanding at the Effective Time. See "The
Merger--Dissenters' Rights" and "--Conditions--Conditions to Obligations of BMS
and BMS Sub".
    

Rights of Stockholders Following the Merger and Distribution

   
     Upon consummation of the Merger and the Distribution, the Former Axion
Stockholders will become stockholders of BMS and AHC. Certain differences exist
between the rights of holders of Axion Common Stock and the rights of holders of
BMS Common Stock and AHC Preferred Stock, respectively, resulting from
differences in the respective Axion, BMS and AHC certificates of incorporation
and by-laws. See "The Transactions" and "Comparison of Certain Rights of Holders
of BMS Common Stock, Holders of Axion Common Stock and Holders of Axion
Preferred Stock" herein and "Comparison of Certain Rights of Holders" in the
Information Statement attached as Appendix G hereto.
    

Interests of Certain Persons in the Transactions

   
     In considering the recommendation of the Axion Board, Axion stockholders
should be aware that certain members of Axion's management and the Axion Board
have certain interests in the Merger and the Distribution that are in addition
to the interests of Axion stockholders generally. These interests include the
following consequences under the Axion 1989 Plan (as defined herein) and the
Axion 1995 Plan (as defined herein) and pursuant to the Merger Agreement with
respect to Axion Options: (i) all Axion Options that had not previously become
exercisable and vested will become fully exercisable and vested in connection
with the Merger; (ii) Axion will extend Employee Loans to each executive
officer, in addition to each current employee or consultant, to enable such
individual to exercise in full his or her Axion Options; and (iii) each officer,
employee or consultant who exercises his or her Axion Options will receive in
the Merger shares of BMS Common Stock, which stock will be freely tradable
    


                                       37

<PAGE>



   
immediately following the consummation of the Merger, subject to contractual
restrictions on the officer's ability to resell the BMS Common Stock and the
limitations set forth under Rule 145 under the Securities Act. As of the Record
Date, options to purchase a total of 1,697,968 shares of Axion Common Stock, at
exercise prices ranging from $0.075 to $10.00 per share, were held by 91 Axion
employees and consultants. It is anticipated that Axion will extend Employee
Loans totaling approximately $6,500,000 to such holders of Axion Options, who
will use such proceeds to exercise Axion Options immediately prior to the Time
of Contribution. Michael D. Goldberg, the President and Chief Executive Officer
and a director of Axion, has advised Axion that he does not intend to exercise
the Goldberg $10.00 Options.

     In addition, OTNC has entered into an employment agreement with David
Levison dated as of August 2, 1996, which agreement becomes effective on the
Closing Date and continues for a period of two years. Pursuant to this
agreement, David Levison will serve as President of OTNC. OTNC has entered into
employment agreements substantially similar to David Levison's (other than
compensation amounts) with Warren Dodge, Bret Brodowy, Michael Cunningham, Lynn
Hammerschmidt and James Adams.

     Axion has entered into separate indemnification agreements with its
directors and officers. These agreements require Axion, among other things, to
indemnify its directors and officers against certain liabilities that arise by
reason of their status or service as directors or officers (other than
liabilities arising from actions not taken in good faith or in a manner the
indemnitee believed to be in the best interests of Axion) and to advance their
expenses incurred as a result of any proceeding against them as to which they
could be indemnified. See "The Merger--Interests of Certain Persons in the
Transactions" and "Effect of Transactions on Axion Employees and Axion Benefit
Plans". The Axion Certificate of Incorporation also provides for exculpation of
directors under certain circumstances. See "Comparison of Certain Rights of
Holders of BMS Common Stock, Holders of Axion Common Stock and Holders of Axion
Preferred Stock--Indemnification of Officers and Directors". In addition, it is
anticipated that AHC will enter into similar indemnification agreements with its
directors and officers, and that the AHC certificate of incorporation and
by-laws will provide, as applicable, for the indemnification of directors and
officers and the exculpation under certain circumstances of directors. See
"Executive Compensation Plans in Effect After the Distribution--AHC
Indemnification Agreements" in the Information Statement attached as Appendix G
hereto.

Vote Required

   
     Approval of the Merger Proposal requires the affirmative vote of (i) at
least a majority of the total number of votes entitled to be cast by holders of
Axion Common Stock and holders of Axion Preferred Stock, voting together as a
single class and (ii) at least a majority of the total number of votes entitled
to be cast by holders of Axion Preferred Stock, voting together as a single
class. Approval of the Preferred Stock Proposal requires the affirmative vote of
least 66-2/3 percent of the total number of votes entitled to be cast by holders
of Axion Preferred Stock, voting together as a single class. It is a condition
to the respective obligations of each party to the Merger Agreement that the
Merger Proposal and the Preferred Stock Proposal be approved. If the Merger is
not consummated, the Preferred Stock Conversion will not be implemented.

     As of the Record Date, the total number of votes entitled to be cast by
holders of Axion Common Stock was 1,606,651, the total number of votes entitled
to be cast by holders of Axion Common Stock and Axion Preferred Stock, voting as
a single class (with each share of Axion Preferred Stock having voting power
equivalent to that of one share of Axion Common Stock) was 8,347,541 and the
total number of votes entitled to be cast by holders of Axion Preferred Stock,
voting as a single class, was 6,740,890.

     As of the Record Date, directors and executive officers of Axion and their
affiliates beneficially owned an aggregate of 1,154,000 shares of Axion Common
Stock, or approximately 71.8% of the shares of Axion Common Stock outstanding on
such date. As of the Record Date, directors and executive officers of Axion and
their affiliates beneficially owned an aggregate of 4,682,322 shares of Axion
Preferred Stock, or approximately 69.4% of the shares of Axion Preferred Stock
outstanding on such date. As of the Record Date, directors and executive
officers of Axion and their affiliates beneficially owned shares of Axion Common
Stock or Axion Preferred Stock representing an aggregate of 69.9% of the total
number of votes entitled to be cast by all stockholders of Axion, voting as a
single class.
    

     As of the Record Date, directors and executive officers of BMS did not
beneficially own any shares of Axion Common Stock or Axion Preferred Stock.

   
     Certain stockholders of Axion which were the beneficial owners, as of the
Record Date, of 1,154,000 shares of Axion Common Stock and 5,741,839 shares of
Axion Preferred Stock have entered into the Stockholder Agreement with BMS and
BMS Sub. Pursuant to the Stockholder Agreement, each such stockholder agreed to
vote all shares of Axion Common Stock and/or Axion Preferred Stock beneficially
owned or subsequently acquired by such stockholder in favor of the Merger
Proposal and the Preferred Stock Proposal, and granted BMS an irrevocable proxy
to so vote such shares. Such shares represent 82.6% of the total number of votes
entitled to be cast by holders of Axion Common Stock and Axion Preferred Stock,
voting together as a single class, and 85.2% of the total number of votes
entitled to be cast by holders of Axion Preferred Stock, voting together as a
single class. Accordingly, the Merger Proposal and the Preferred Stock Proposal
can be approved by the affirmative vote of such shares even if all other
stockholders of Axion vote against the Merger Proposal and the Preferred Stock
Proposal. The Stockholder Agreement also prohibits such stockholders from
transferring their shares of Axion Common Stock or Axion Preferred Stock until
the Merger is consummated or the Merger Agreement is terminated.

     In addition, it is a condition to the obligation of BMS to effect the
Merger that no Dissenting Shares be outstanding at the Effective Time. See "Risk
Factors--Vote Required; Stockholder Agreement" and "The Merger--Dissenters'
Rights" and "--Conditions--Conditions to Obligations of BMS and BMS Sub".

Voting and Revocation of Proxies

   
     A majority of the shares entitled to vote at the Special Meeting,
represented in person or by proxy, constitutes a quorum; provided that with
respect to matters submitted at the Special Meeting solely to a vote of holders
of Axion Preferred Stock, voting as a single class, a majority of shares of
Axion Preferred Stock entitled to vote at the Special Meeting, represented in
person or by proxy, constitutes a quorum. Under the DGCL, in determining whether
the Merger Proposal has received the requisite number of affirmative votes,
abstentions and broker non-votes will be counted and will have the same effect
as a vote against such proposal. Holders of record of Axion Common Stock at the
close of business on the Record Date are entitled to one vote at the Special
Meeting per share of Axion Common Stock held. When voting with holders of Axion
Common Stock, each holder of record of any series of Axion Preferred Stock is
entitled to the number of votes equal to the number of shares of Axion Common
Stock into which such holder's shares of such series of Axion Preferred Stock
could be converted at the close of business on the Record Date. As a result,
each share of Axion Preferred Stock will in effect have the voting power of one
share of Axion Common Stock. When voting as a class with other holders of Axion
Preferred Stock, holders of any series of Axion Preferred Stock are entitled to
one vote per share of Axion Preferred Stock held.
    

     Shares of Axion Common Stock or Axion Preferred Stock represented by
properly executed proxies in the form enclosed with this Proxy
Statement/Prospectus will, unless such proxies have previously been revoked, be
voted in accordance with the instructions indicated in such proxies. To the
extent instructions are not indicated, shares will be voted FOR the Merger
Proposal and, if applicable, FOR the Preferred Stock Proposal and in the
discretion of the proxy holder as to any other matter that may properly come
before the Special Meeting. The Axion Board knows of no business that will be
presented at the Special Meeting other than the matters described in this Proxy
Statement/Prospectus. An Axion stockholder who has given a proxy may revoke such
proxy at any time prior to its exercise at the Special Meeting by (i) giving
written notice of revocation bearing a later date than the proxy to the
Secretary of Axion, (ii) properly submitting to Axion a duly executed proxy card
relating to the same shares bearing a later date or (iii) attending the Special
Meeting and voting in person. Attendance at the Special Meeting will not in and
of itself revoke a proxy. All written notices of revocation and other
communications with respect to revocation of proxies by stockholders should be
addressed as follows: Axion Inc., c/o Gunderson Dettmer Stough Villeneuve
Franklin & Hachigian, LLP, 600 Hansen Way, Second Floor, Palo Alto, California
94304, Attention: Steven M. Spurlock, Esq., or hand-delivered to Mr. Spurlock at
the foregoing address, before the vote is taken at the Special Meeting.

     STOCKHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THE ENCLOSED PROXY
CARD. IF THE MERGER IS CONSUMMATED, STOCKHOLDERS WILL BE SENT A LETTER OF
TRANSMITTAL WITH INSTRUCTIONS FOR SURRENDERING THEIR CERTIFICATES REPRESENTING
SHARES OF AXION COMMON STOCK. See "The Merger--Exchange of Certificates in the
Merger".

Solicitation of Proxies

   
     Officers and regular employees of Axion may, without being additionally
compensated, solicit proxies by mail, telephone, telegram or personal contact.
Estimated proxy solicitation expenses of $5,000 will be paid by Axion in
connection with the solicitation of proxies for the Special Meeting. Axion does
not currently intend to employ any other party to assist in the solicitation
process.

Dissenters' Rights

   
     Holders of Axion Common Stock will be entitled to dissenters' rights in
connection with the Merger. It is a condition to the obligation of BMS to
consummate the Merger that no Dissenting Shares be outstanding at the Effective
Time. See "Risk Factors--Vote Required, Stockholder Agreement" and "The
Merger--Dissenters' Rights" and "--Conditions--Conditions to Obligations of BMS
and BMS Sub".
    

                                THE TRANSACTIONS

   
     Pursuant to the transactions described in this Proxy Statement/Prospectus,
BMS will acquire the Retained Business, which consists of (i) OTNC, including
its interest in the Partnership, which distributes oncology drugs and related
supplies to office-based oncologists, and (ii) OPUS, which at the Effective Time
will contain only the OPUS Station Business, which furnishes automated drug
dispensing and inventory tracking systems to office-based oncology practices.

     The proposals to be submitted to Axion stockholders at the Special Meeting
relate to the acquisition by BMS from Axion of the Retained Business. The
acquisition of the Retained Business by BMS will be effected through a series of
sequential transactions, including the Contributions, the Distribution and the
Merger, all as set forth in the Merger Agreement and the Distribution Agreement.
Prior to the Effective Time, the Acquired Business will be transferred to AHC
and OPUS Sub, and the AHC Preferred Stock will be distributed to the
stockholders of Axion in the Distribution. After the Distribution and at the
Effective Time, Axion will hold the Retained Business, so that BMS will
effectively acquire the Retained Business in the Merger. The purpose of this
complex structure is to permit the disposition of the Retained Business in a
transaction that should be tax free to Axion's stockholders in which
stockholders of Axion will receive BMS Common Stock and will also retain their
proportionate equity interests in the Acquired Business in the form of AHC
Preferred Stock to be received in the Distribution. See "Risk Factors--Certain
Federal Income Tax Consequences" and "Certain Federal Income Tax Consequences".
For information regarding the Acquired Business and the AHC Preferred Stock, see
the Information Statement attached as Appendix G hereto.

                                  THE COMPANIES

Axion

     General

   
     Axion was incorporated under the laws of the State of Delaware on July 30,
1987. Axion is a holding company with three direct wholly owned subsidiaries,
OTNC, AHC and OPUS. OTNC is the general partner of the Partnership, which
distributes oncology drugs and related supplies to office-based oncologists (the
"OTN Business"). Axion's investment in the Partnership constitutes Axion's
principal business, representing 98.2% and 99.9%, respectively, of Axion's
consolidated total revenues and all of Axion's consolidated income from
operations during 1995 and for the six months ended June 30, 1996, and
representing approximately 98.5% of Axion's consolidated total assets at June
30, 1996.

     AHC expects that the AHC Business, its principal business, will consist of
providing cancer-specific managed care services to cancer care payers and
providers. The AHC Business has generated limited revenues, and has incurred
losses since AHC's formation in 1994. AHC was formed to carry on the clinical
studies programs which Axion began in 1987 and to continue the development of
oncology disease management programs arising from such clinical studies
programs. OPUS consists of the OPUS Station Business and the OPUS Matrix
Business. The OPUS Station Business furnishes automated drug dispensing and
inventory tracking systems to office-based oncology practices. The OPUS Station
Business has not generated significant revenues, and has operated at a loss
since its inception in 1994. The OPUS Matrix Business consists of (i) computer
software which provides office-based oncology practices with access to drug and
treatment information and (ii) the management information systems currently used
to support Axion's businesses. The OPUS Matrix Business has incurred losses
since its inception in 1994.

     Axion is also the beneficial owner of 2,700,000 shares of OnCare Preferred
Stock. OnCare is an oncology physician practice management company formed by
Axion in June 1995. On December 31, 1995, Axion distributed to holders of Axion
Common Stock, holders of Axion Options and holders of Axion Preferred Stock all
Axion's holdings of shares of common stock of OnCare (representing 88.8% of the
common stock of OnCare then outstanding). At the time of such distribution Axion
acquired 700,000 of the shares of OnCare Preferred Stock it currently holds in
exchange for cancellation of a $3.5 million portion of a loan previously made by
Axion to OnCare. In February and March of 1996, Axion spent an additional $10
million to acquire the other 2,000,000 shares of OnCare Preferred Stock it
currently holds.

     As a result of the distribution of the Preference Amount, the Contributions
and the Distribution, OTNC, including its interest in the Partnership, and the
OPUS Station Business, including the assets and certain of the liabilities
relating thereto (collectively, the "Retained Business"), will constitute all
the business, assets and liabilities of Axion at the Effective Time. The
Acquired Business, which will include, among other things, the AHC Business, the
OPUS Matrix Business, the OnCare Preferred Stock, all cash and cash equivalents
of Axion and its subsidiaries (other than Retained Cash) and the Employee Loans,
will be distributed to Axion's stockholders in the Distribution immediately
prior to the Merger, and, accordingly, is not described in the remainder of this
section (except as the Acquired Business relates to matters discussed under
"--Facilities", "--Employees" and "--Trademarks" herein).

     At June 30, 1996, Axion and its consolidated subsidiaries had total assets
of approximately $159.1 million and stockholders' equity of approximately $27.6
million, and the Retained Business had total assets of approximately $156.9
million, or approximately 98.6% of Axion's consolidated total assets, and
stockholders' equity of $26.7 million, or approximately 98.6% of Axion's
consolidated stockholders' equity. For the six months ended
    


                                       46




<PAGE>
 

<PAGE>



   
June 30, 1996, and the year ended December 31, 1995, the Retained Business
accounted for approximately $133.1 million, or approximately 99.9%, and $195.3
million, or approximately 98.2%, respectively, of Axion's consolidated net
revenues.

     The Acquired Business has not, to date, realized significant revenues, and
has operated and continues to operate at a loss, with funding provided by Axion.
For further information about the Acquired Business, see the Information
Statement attached as Appendix G hereto.

     Oncology Therapeutics Network

     OTN is a distributor of oncology drugs and related supplies to office-based
oncologists. OTN provides a range of oncology products and supplies from a
variety of manufacturers, reducing the need for its customers to interact with
multiple suppliers. OTN's product catalog has over 700 line items from over 45
manufacturers. In addition, OTN is BMS's exclusive sales agent for sales of BMS
oncology products to U.S. office-based oncologists. A small number of products
account for a majority of OTN's net revenues. Specifically, sales of Kytril(TM),
Zofrank(R) and Neupogenk(R), supportive care medicines manufactured by
SmithKline Beecham PLC, Glaxo-Wellcome PLC and Amgen, Inc., respectively,
accounted for approximately 10%, 16%, and 24% of OTN's net revenues in 1995.
Since the launch of the Oncology Therapeutics Network in September 1990, the
annual dollar volume of products shipped by it has grown from approximately
$16.4 million in 1991 to approximately $459 million (including $274 million in
shipments of BMS oncology products by OTN as exclusive sales agent for BMS
oncology products, which are not included in net revenues of the Partnership) in
1995 and the number of customers served has grown from approximately 370 in 1991
to over 2,200 in 1995.

     The wholesale market for cancer pharmaceuticals has grown rapidly over
recent years, according to industry estimates. The industry has seen a shift
from the administration of chemotherapy almost exclusively in the hospital
setting to increased administration of chemotherapy in physicians' offices
outside the hospital, primarily, in Axion management's view, as a result of cost
containment pressures and improvements in the management of the severe side
effects of chemotherapy through the use of supportive care pharmaceuticals.
Hospital-based oncologists are typically served by drug wholesalers, who provide
daily deliveries of large quantities of pharmaceutical products, including
oncology drugs and related supplies, to hospital pharmacies. Hospital-based
oncologists rely on hospital pharmacies to order, receive and inventory drugs as
well as to maintain clinical drug information. Office-based oncologists, lacking
a hospital pharmacy and related services and support, generally face significant
administrative burdens when ordering, stocking and paying for oncology drugs and
related supplies. OTN's objective is to address the cost containment needs and
reduce the administrative burdens of office-based oncologists by attempting to
serve as a convenient, cost-effective, single source of supply of oncology drugs
and related supplies, to reduce inventory and other associated carrying costs,
to increase the productivity of the oncology office, and to provide reliable,
customer-oriented service as well as clinical information regarding cancer
pharmaceuticals and related topics.

     OTN believes that its extensive customer base, coupled with what OTN
considers its overall competitive pricing and customer service, also makes it
attractive to drug manufacturers that wish to serve the fragmented office-based
oncologist community through a focused distribution channel. OTN provides
services to manufacturers that include support for product launch,
customer-specific marketing programs, product sampling and market research. OTN
believes that these services are of particular interest to new manufacturer
entrants who are interested in selling products to office-based oncologists but
have not yet established relationships with the medical oncology community.

     OTN Strategy. OTN's strategy is to expand its distribution business by
attracting new customers and increasing sales of both BMS and other
manufacturers' oncology products to existing accounts through coordinated sales
and marketing efforts with the BMS oncology sales forces and by expanding its
relationships with other manufacturers
    


                                       47

of cancer pharmaceuticals. In addition, OTN intends to continue to integrate its
services with the capabilities of OPUS Station units in order to promote, and
capitalize on, the growth of the OPUS Station Business. As discussed below, due
to such integration, in order to realize the full benefits of OPUS Stations,
such as automatic reordering of inventory and data reports, OPUS Station
customers need to order most of their oncology drugs from OTN.

     OTN Operations. The majority of OTN's staff is based at OTN's headquarters
in South San Francisco, California. OTN generates sales principally through
telephone sales, a field sales organization and direct mail. Customers can place
orders through a toll-free number from 5:30 a.m. to 5:30 p.m. Pacific time.
Orders are electronically transmitted to one of two warehouse sites, located in
Delaware and southern California, where orders are picked up, packaged and
shipped. These warehouses are operated by a third-party warehousing services
company. OTN maintains inventory levels at these sites intended to be sufficient
to meet anticipated demand.

     OTN Sales, Marketing and Customer Support. OTN's internal sales force and
customer service personnel consist of approximately 37 individuals who service
and solicit customers primarily through telephone sales, direct customer contact
and direct mail efforts. In addition, OTN has four national account managers
working in the field whose responsibilities include establishing and maintaining
relationships with OTN's largest customer accounts. OTN's internal sales and
service operations build upon and are coordinated with those of the BMS oncology
sales forces. The BMS oncology sales forces and OTN's sales force together
provide nationwide coverage of over 2,200 customers and sites via telephone
sales and in-person contacts.

     EDS Contract. Axion contracted with Electronic Data Systems Corporation
("EDS") in July, 1993 to provide information technology services. EDS provides
dedicated personnel and supplies the hardware and software identified by Axion
and EDS as necessary to meet Axion's information technology needs including
sales, service, finance and accounting functions as well as electronic links to
Axion's partners and customers.

     Sales Agency Agreement. Pursuant to a Sales Agency Agreement between BMS
and OTN (the "Sales Agency Agreement"), OTN is BMS's exclusive sales agent for
sales of BMS oncology drugs and biologics to U.S. office- based oncologists. The
Sales Agency Agreement does not, however, prevent other distributors from
reselling BMS oncology products to U.S. office-based oncologists, although BMS
is precluded from selling its oncology products to such distributors at prices
below those charged by BMS for BMS oncology products sold through OTN. OTN
facilitates BMS's sales of oncology products by providing distribution services
at competitive prices to office-based oncologists. Unlike OTN's oncology product
distribution arrangements with other manufacturers, OTN does not purchase
oncology products from BMS for resale. Instead, OTN receives a commission for
BMS oncology products distributed by OTN and, as a result, does not record
product revenues from sales of such products. BMS retains the right to control
pricing and product-related decisions. Currently, OTN is responsible for
collecting (and financing) payments from sales of BMS oncology products for up
to 180 days, and, within 60 days after shipment, remits to BMS the amount of the
receivable for such shipment less commissions. BMS reimburses OTN for the
portion of OTN's financing costs that relate to the sale of BMS oncology
products. BMS ultimately retains the collection risk of receivables arising from
its product sales.

     OTN Partnership Agreement. Axion formed the Oncology Therapeutics Network
in September 1990 to distribute oncology drugs and related supplies and to
provide clinically oriented services to office-based oncologists. In July 1993,
the Partnership was formed pursuant to a Limited Partnership Agreement (the
"Partnership Agreement") between Axion's wholly owned subsidiary, OTNC, as
general partner and BMS's wholly owned subsidiary, BMOTN, as limited partner.
Axion contributed its Oncology Therapeutics Network business (excluding any
debts or obligations) to the Partnership and agreed to provide all
administrative, operational and other services necessary to support the
Partnership, subject to reimbursement for its costs by the Partnership. Pursuant
to the Sales Agency Agreement, BMS appointed the Partnership as its exclusive
sales agent for BMS oncology products (and
    


                                       48




<PAGE>
 

<PAGE>



   
any other oncology products that BMS has the right to sell) to U.S. office-based
oncologists and agreed to promote the Partnership's business with its oncology
sales forces. Each partner also contributed cash to the Partnership and BMS
contributed certain customer lists.

     OTNC manages the day-to-day operations of the Partnership and a management
committee retains authority for major Partnership business decisions. Such
management committee currently consists of six members, two designated by the
general partner, two designated by the limited partner and two designated by
mutual agreement of the general partner and the limited partner. Pursuant to an
amendment to the Partnership Agreement dated as of August 2, 1996, BMOTN may, at
any time prior to October 31, 1996, designate a seventh member of the management
committee who, until October 31, 1996, shall have the deciding vote in the event
of any deadlock of such committee.

     All obligations of each partner to the other under the Partnership
Agreement are unconditionally guaranteed by their respective parent
corporations. Additional capital contributions by the partners are not required.

     The Partnership has a term of 20 years, but can be terminated on either
January 1, 2003 or January 1, 2008 at BMS's option upon at least one year's
prior notice. In addition, the right to terminate the Partnership Agreement and
the Sales Agency Agreement arises under certain circumstances, including
material breach of either agreement, bankruptcy, insolvency or a Change in
Control of Axion. A "Change in Control" for purposes of the Partnership
Agreement and the Sales Agency Agreement includes the sale or other transfer,
directly or indirectly, of a person or substantially all its assets and
business, or a controlling interest therein (including in connection with a
merger or by operation of law). In addition, a Change of Control of OTN or OTNC
is treated under the Sales Agency Agreement as an assignment requiring BMS's
consent, which BMS may withhold in its sole discretion. Such an assignment
without BMS's consent constitutes a material breach of the Agreement, and would
entitle BMS (or BMOTN, as applicable) to terminate the Sales Agency Agreement
and the Partnership Agreement.

     In the event the Partnership Agreement is terminated because of a material
breach of the Partnership Agreement or Sales Agency Agreement, the non-breaching
partner is required to elect either to purchase the other partner's interest or
to cause the other partner to purchase the non-breaching partner's interest in
the Partnership, at fair market value as determined by a nationally recognized
investment banking firm selected by the partners. Under certain circumstances
involving bankruptcy or insolvency, upon termination of the Partnership
Agreement, the terminating partner may, but is not required to, elect to
purchase the other partner's interest or to cause the other partner to purchase
the terminating partner's interest in the Partnership, at fair market value
determined as set forth above. In addition, in the event that the Sales Agency
Agreement is terminated as a result of a change in control of Axion, or BMS
exercises its right to terminate the Sales Agency Agreement in 2003 or 2008, BMS
is required to sell, and Axion is required to buy, BMS's interest in the
Partnership, at fair market value determined as set forth above.

     Under certain circumstances, upon termination of the Sales Agency
Agreement, either party may elect to extend the Sales Agency Agreement for
varying periods specified in such Agreement; provided that during the term of
such extension the agency granted to OTN thereunder will no longer be exclusive.

     OTNC receives an annual preferential allocation of profits during the first
several years of the term of the Partnership as follows: in 1993, the first
$900,000 in profits would have been allocated to OTNC if the Partnership had
earned profits, with the balance allocated 80% to OTNC and 20% to BMOTN; in
1994, this preference was $4.9 million with the balance allocated 80:20 in favor
of OTNC; in 1995, the preference was $10.2 million with the balance allocated
80:20; in 1996, the preference is $18.75 million with the balance allocated
80:20; and in 1997 and thereafter, the preference is zero, with profits
allocated 70:30 in favor of OTNC in 1997, 60:40 in favor of
    


                                       49

<PAGE>



   
OTNC in 1998, and 50:50 in 1999 and thereafter. The preferences due are
cumulative; any unallocated preference is carried forward for allocation in
later years, together with interest at the prime rate on the accumulated unpaid
preference. The aggregate preference of OTNC over the term of the Partnership,
excluding interest, is $34.75 million, of which approximately $11.9 million has
been paid through June 30, 1996, including $4.8 million paid for the year ended
December 31, 1995 and $7.1 million paid for the six months ended June 30, 1996.
Immediately prior to the Merger, the Preference Amount, totaling $13,615,147 in
cash, will be paid by OTN to OTNC. Losses are allocated equally among the
partners, but losses are not allocated to BMOTN to the extent that such
allocation would take BMOTN's capital account to less than zero.
    

     OPUS Station Business

   
     The OPUS Station Business consists of a computerized drug dispensing and
inventory tracking system that provides secure medication and supply storage,
captures billing information at the time of care, and produces practice-specific
reports on drug usage for office-based oncology practices. The system dispenses
medication stored in the OPUS Station unit ("OPUS Station"), automatically
reorders inventory when integrated with OTN's ordering system and produces
billing records and other reports based on patient and drug selection
information input by office staff. The reports generated by the OPUS Stations
provide information on drug usage by physician, patient, diagnosis, and
treatment regimen and can assist practices in evaluating the relative costs of
chemotherapy regimens used within the practice. The OPUS Station Business has
not generated significant revenues, and has operated at a loss since its
inception in 1994.

     The OPUS Station is based on technology licensed from the Pyxis Corporation
("Pyxis") pursuant to an agreement dated May 5, 1995 (the "Pyxis Agreement").
Under the terms of the Pyxis Agreement, OPUS acquired the exclusive right from
Pyxis to promote and market its point-of-use systems, or components that make up
the OPUS Station units, for use in out-patient oncology practices. In addition,
the agreement provides that OPUS must lease a minimum number of OPUS Station
units, from Pyxis on the terms set forth therein and Pyxis must provide OPUS
with service for such units. Pyxis has the right to change the rental rates and
service fees it charges for units leased by OPUS upon 60 days' prior written
notice, but must honor the rental rates and service fees in effect under
existing OPUS Station rental agreements and OPUS Station service agreements for
the duration of their terms. The Pyxis Agreement terminates on December 31, 1997
unless mutually extended by the parties thereto.

     As of June 30, 1996, a total of 91 OPUS Stations were in active use at 68
different oncology practices, including eight OPUS Stations in use at six
different oncology practices operated by OnCare. When an oncology practice
orders an OPUS Station, OPUS Station technicians travel to the installation
site, install the machines, and train the office staff. The OPUS Station units
are typically leased to customers on a month-to-month basis or for an extended
term with a 30- or 60-day notice of cancellation; lease payments typically
include the rental cost of the equipment and all service.The OPUS Station
Business has not had significant revenues from the rental of equipment and has
operated at a loss since inception.

     In order to realize the full benefits of OPUS Station (automatic reordering
of inventory and data reports), OPUS Station customers need to order most of
their oncology drugs from OTN. Purchases of oncology drugs from OTN by OPUS
Station customers typically exceed 80% of their total oncology drug purchases.

     Competition

     In Axion's opinion, the environment in which OTN operates is intensely
competitive, and OTN has a number of current and potential competitors,
including drug manufacturers and drug wholesalers that are members of the
National Wholesale Druggists Association ("NWDA"), a significant number of which
have substantially greater
    


                                       50




<PAGE>
 

<PAGE>



   
financial, technical marketing and human resources capabilities than OTN and
some of which distribute BMS and other manufacturers' oncology products to
office-based oncologists. Established NWDA distributors to hospitals are also
engaging in distributing oncology products to office-based oncologists. Axion
expects additional competition from other established and emerging companies,
particularly if the community of office-based oncologists continues to develop
and expand. Increased competition could result in price reductions, reduced
margins and loss of market share, any of which could materially and adversely
affect OTN and Axion. Axion believes that the principal competitive factors in
the distribution of oncology drugs and related supplies are price, quality of
customer service, technical support and reputation. There can be no assurance
that OTN will be able to compete successfully against current or future
competitors or that competitive pressures faced by OTN, including exclusive
marketing arrangements with respect to key products or superior marketing
capabilities possessed by competitors, will not materially and adversely affect
Axion's business, financial condition and results of operations.

     Government Regulation

     Various federal and state statutes and regulations govern or influence the
labeling, storage, recordkeeping, reporting, distribution, promotion and
marketing of oncology products. Any failure of OTN or its agents or suppliers to
comply with these and other regulatory requirements could subject Axion to
regulatory and judicial enforcement actions, including but not limited to
product recalls or seizures, injunctions and civil and criminal penalties.
Moreover, if products OTN distributes are withdrawn from the market, Axion's
business, financial condition and results of operations could be materially and
adversely affected.

     As a marketer and distributor of pharmaceutical products, OTN is directly
subject to Food and Drug Administration ("FDA") administered laws and
regulations pertaining to the promotion and distribution of such products. The
FDA regulates these matters rigorously, and its enforcement policies and
practices in these areas undergo periodic review and modification. Were the FDA
to apply these laws and regulations in such a manner as to require alterations
in OTN's current practices, Axion's business, financial condition and results of
operations could be adversely affected. OTN may also be affected by government
regulation of the products it distributes and of the manufacturers of such
products.

     Even if regulatory approvals have been obtained by a manufacturer for a
product, a marketed drug and its manufacturer are subject to ongoing review by
the FDA, and later discovery of previously unknown problems with a product or
manufacturer may result in restrictions on the product or its manufacturer,
including withdrawal of the product from the market. In addition, there can be
no assurance that review or actions by the FDA or other regulatory authorities
will not involve delays adversely affecting the marketing and sales of products
sold and proposed to be sold by OTN.

     OTN's marketing activities are also regulated under federal and state laws
and regulations governing sales practices, including discounting, for health
care products and services (so-called "anti-kickback" laws). These laws and
regulations are broad in scope and are subject to frequent modification and
reinterpretation. Any application of such laws and regulations by a governmental
authority to OTN's marketing practices so as to require alteration of those
practices could have an adverse effect on Axion's business, financial condition
and results of operations. There can be no assurance that OTN's marketing
activities will be determined to be in compliance with applicable laws and
regulations. Noncompliance with such laws and regulations could materially
adversely affect Axion's business, financial condition and results of
operations.

     Litigation

     In the ordinary course of its business, Axion may be subject from time to
time to claims and legal actions. Axion has no history of claims or actions
which have had a material effect on its business, financial condition or results
of operations.

     In the ordinary course of its business, Axion (through its subsidiaries)
purchases and resells pharmaceutical products and related medical supplies. As a
result, Axion faces the risk of product liability claims and there can be no
assurance that it will avoid significant product liability exposure. Axion does
not have product liability insurance, and there can be no assurance that a
product liability claim, whether ultimately successful or not, would not have a
material adverse effect on the business, financial condition and results of
operations of Axion.

BMS

   
     BMS was incorporated under the laws of the State of Delaware in August 1933
under the name Bristol-Myers Company as successor to a New York business started
in 1887. In 1989, the Bristol-Myers Company changed its name to Bristol-Myers
Squibb Company, as a result of a merger. BMS, through its divisions and
subsidiaries, is a major producer and distributor of pharmaceutical products,
medical devices, nonprescription health products, toiletries and beauty aids. At
June 30, 1996, BMS had total assets of approximately $13,750 million and
stockholders' equity of approximately $6,065 million.

     BMS's principal executive offices are located at 345 Park Avenue, New York,
New York 10154-0037 and its telephone number at such offices is (212) 546-4000.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                  CONDITION AND RESULTS OF OPERATIONS OF AXION
                            (in thousands of dollars)

   
     The following discussion contains forward-looking statements. Axion's
actual results could differ materially from those discussed in the
forward-looking statements. Factors that could cause or contribute to such
differences include those discussed below and elsewhere in this Proxy
Statement/Prospectus, particularly in "Risk Factors" herein and in "Special
Factors" in the Information Statement attached as Appendix G hereto.
    

Overview

   
     Axion's principal business is the OTN Business. Axion formed the Oncology
Therapeutics Network in September 1990 to distribute oncology drugs and related
supplies (collectively, "oncology products") and to provide clinically oriented
services to office-based oncologists. In July 1993, to expand the OTN Business,
Axion formed the Partnership with BMS. Axion contributed its existing
distribution business to the Partnership and BMS agreed to provide the
promotional support of its oncology products sales forces and also appointed the
Partnership the exclusive sales agent to U.S. office-based oncologists for BMS
oncology products. Unlike OTN's oncology product distribution arrangements with
other manufacturers, OTN does not purchase oncology products from BMS for
resale. Instead, OTN receives a commission for BMS oncology products distributed
by OTN and, as a result, does not record product revenues from sales of such
products. BMS retains the right to control pricing and product-related decisions
with respect to BMS oncology products. Currently, OTN is responsible for
collecting (and financing) payments from sales of BMS oncology products for up
to 180 days, and, within 60 days after shipment, remits to BMS the amount of the
receivable for such shipment less commissions. BMS reimburses OTN for the
portion of OTN's financing costs that relate to the sale of BMS oncology
products. BMS ultimately retains the collection risk of receivables arising from
its product sales.

     Axion consolidates the Partnership in the Axion financial statements. The
Partnership represents the most significant portion of Axion's consolidated
total assets and revenues and accounts for all of Axion's consolidated income
from operations.

     Since its formation in 1987, Axion has engaged in several other
oncology-focused businesses. None of those businesses has achieved substantial
revenues or operated profitably to date. Those businesses include: its oncology
clinical studies programs started in 1987; its oncology drug development
activities started in 1992 and terminated in 1993; the development of its
oncology disease management programs begun in 1994 arising from its oncology
clinical studies programs; its oncology information systems activities, begun in
1994; and its oncology physician practice management business started in June
1995 and distributed (except for the OnCare Preferred Stock held by Axion) to
Axion's stockholders in December 1995.

     AHC was formed in late 1994 to carry on the clinical studies programs begun
by Axion in 1987 and to continue the development of oncology disease management
programs arising from such clinical studies programs. AHC expects that the AHC
Business, its principal business, will consist of providing cancer-specific
managed care services to cancer care payers and providers. The AHC Business has
generated limited revenues and has incurred losses since AHC's formation and is
not expected to operate profitably in the foreseeable future.

     OPUS was formed in late 1994 to own and operate all of Axion's information
technology assets and resources. OPUS consists of the OPUS Station Business and
the OPUS Matrix Business. The OPUS Station Business furnishes automated drug
dispensing and inventory tracking systems to office-based oncology practices.

Business has not generated significant revenues, and has operated at a loss
since its inception in 1995, and is not expected to operate profitably in the
foreseeable future. The OPUS Matrix Business consists of (i) computer software
which provides office-based oncology practices with access to drug and treatment
information and (ii) the management information systems to support Axion's
businesses. Pursuant to an agreement with EDS, OPUS has an irrevocable,
perpetual, worldwide exclusive license for the computer software used in the
OPUS Matrix Business. The OPUS Matrix Business has incurred losses since its
inception in 1994, and is not expected to operate profitably in the foreseeable
future.


     OnCare was formed in June 1995 to acquire and manage oncology physician
practices. On December 31, 1995, Axion distributed to holders of Axion Common
Stock, holders of Axion Options and holders of Axion Preferred Stock all Axion's
holdings of shares of common stock of OnCare (representing 88.8% of the common
stock of OnCare then outstanding). At the time of such distribution Axion
acquired 700,000 shares of OnCare Preferred Stock in exchange for cancellation
of a $3,500 portion of a loan previously made by Axion to OnCare. In February
and March of 1996, Axion spent an additional $10,000 to acquire 2,000,000
additional shares of OnCare Preferred Stock.

     The comments which follow relate to Axion's consolidated results of
operations and liquidity and capital resources. Included in the consolidated
operating results are combined amounts for OnCare in 1995 and AHC and OPUS
(including the OPUS Station and OPUS Matrix Businesses) for the year ended
December 31, 1995 and the six months ended June 30, 1995 and 1996. Net revenues
and net loss amounts for combined OnCare, AHC and the OPUS Matrix Business for
the year ended December 31, 1995 are $3,615 and $2,094, respectively. Net
revenues and net loss amounts for AHC and the OPUS Matrix Business for the
six-month period ended June 30, 1995 are $253 and $844, respectively. Net
revenues and net loss amounts for AHC and the OPUS Matrix Business for the
six-month period ended June 30, 1996 are $104 and $1,376, respectively.
    

Results of Operations

     Three years ended December 31, 1995

   
     Net revenues increased in excess of $70,000 annually in each of the past
two years, from $56,052 in 1993 to $126,369 in 1994 to $198,950 in 1995.
Substantially all of these net revenues arose from the OTN Business. Net
revenues included commissions from BMS to the Partnership of $1,440 in 1993,
$6,527 in 1994 and $9,412 in 1995 as compensation for the Partnership's services
as exclusive sales agent for BMS oncology products. No product sales revenues
are recorded by the Partnership in connection with its role as agent for the
sale of BMS oncology products. The substantial increases in net revenues,
including the increases in BMS commissions, in each of 1994 and 1995 were
attributable principally to a continued increase in product shipments as a
result of increased penetration of existing customer accounts and, to a lesser
degree, to an increase in the number of OTN's customers. The balance of such
increases was attributable to increases in the prices of the oncology products
distributed by OTN, which typically reflect a pass-through of manufacturers'
price increases to the Partnership. There can be no assurance that net revenues
will continue to grow, if at all, at the same rate achieved in the past two
years.

     Total costs and expenses increased from $59,982 in 1993 to $122,937 in 1994
to $189,741 in 1995, representing 107%, 97% and 95% of net revenues in 1993,
1994 and 1995 respectively. Cost of revenues, which represent the principal
component of total costs and expenses, represented 91.0%, 89.1% and 88.6% of net
revenues in 1993, 1994 and 1995, respectively. The principal component of cost
of revenues is the purchase cost of oncology products, which remained relatively
constant as a percentage of net revenues during the three-year period due to the
Partnership's efforts to maintain relatively stable mark-up percentages over
purchase cost in establishing selling prices. The decline in cost of revenues
during the three-year period is primarily attributable to a decrease in
    


                                       55




<PAGE>

warehouse and distribution costs as greater shipment volumes have allowed the
Partnership to achieve economies of scale with respect to its warehouse and
distribution costs.

     Sales and marketing costs and general and administrative costs declined as
a percentage of net revenues over the three-year period due to the OTN
Business's ability to leverage its existing infrastructure over greater shipment
volumes. Sales and marketing expenses as a percentage of net revenues decreased
from 3% in 1993 to 2% in 1994 and 1% in 1995. General and administrative
expenses as a percentage of net revenues decreased from 10% in 1993 to 7% in
1994 and 6% in 1995.

     Axion incurred costs of $1,607 in connection with its product development
program in 1993. These activities were terminated in August 1993. See Note 6 of
Notes to Consolidated Financial Statements on F-13.

     In 1993, Axion incurred a loss from operations of $3,930. The substantial
increase in net revenues in each of 1994 and 1995, together with the beneficial
effects on total costs and expenses resulting from an increasing scale of
operations, resulted in income from operations of $3,432 in 1994 and $9,209 in
1995. All of the income from operations in each of 1994 and 1995 was
attributable to the OTN Business. Axion's other businesses operated at a loss
during the three-year period.

     Other expense, net was $36 in 1993, $2,004 in 1994 and $135 in 1995. Other
expense, net consists principally of amounts related to the financing of the
Partnership's accounts receivable under various arrangements. From August 1993
until September 1994, to facilitate the provision of credit to OTN customers and
to reduce the requirement for other working capital financing, the Partnership
and BMS entered into agreements with General Electric Capital Corporation
("GECC") for the sale of eligible accounts receivable (both BMS and non-BMS
oncology product related), subject to a 25% cash holdback by GECC of the
uncollected balance. Proceeds from the sale of BMS and non-BMS oncology
product-related accounts receivable were remitted directly by GECC to the
Partnership, less the holdback. Also included in the $36 of other expense, net
in 1993 was income of $996, classified as minority interest and representing
BMOTN allocated share (50%) of the Partnership's net loss for the period from
inception of the joint venture in August 1993 through December 31, 1993. The
Partnership operated profitably after 1993 and all of those profits were
allocated to Axion's interest (none to BMS) under the preferential allocation
formula in the Partnership Agreement. See "The Companies--Axion--Oncology
Therapeutics Network--OTN Partnership Agreement".

     Because the Partnership is not required to pay BMS for BMS oncology product
sales for 60 days, during the one-year period that the GECC arrangements were in
effect, the Partnership had net funds available for investment and recognized
interest income. Axion reported interest income of $490 in 1993, $1,306 in 1994
and $756 in 1995. Interest income varies from year to year as a result of the
amount of cash invested from operations, typically on a short-term basis. GECC
fees, less reimbursements from BMS of a portion thereof, were $1,407 in 1993 and
$2,945 in 1994. These fees were reported as other nonoperating expense in those
years. Axion reported interest expense of $115 in 1993, $365 in 1994 and $1,037
in 1995. Interest expense increased significantly from 1994 to 1995 as a result
of the termination of the GECC agreements and the replacement thereof with, for
the period from September 1994 through January 1995, bridge loans, initially
from both Axion and BMS but eventually from BMS alone, and then in January 1995
a revolving bank credit facility for up to $50,000, which financed increased
borrowings to fund working capital requirements arising from increased product
shipments and revenue levels.

     In 1993, Axion incurred a loss before provision for income taxes of $3,966.
In 1994, Axion reported $1,428 of income before provision for income taxes and
the same amount of net income, due to a $7,362 increase in income from
operations, which resulted from growth in revenues. No income tax provision was
necessary in 1994 because of the availability of previously unrecognized net
operating loss carryovers. In 1995, income before
    


                                       56




<PAGE>
 

<PAGE>



   
provision for income taxes increased $7,646 to $9,074, due to a $5,777 increase
in income from operations, which resulted from growth in revenues and associated
economies of increased scale of operations and a $1,869 reduction in other
expense, net primarily due to the termination of the arrangements for sale of
receivables to GECC. A $1,187 provision for income taxes in 1995 reduced net
income in 1995 to $7,887. The 13% effective rate of the income tax provision in
1995 reflected the remaining benefit from previously unrecognized net operating
loss carryovers which were fully utilized in 1995.

     Six months ended June 30, 1996 and 1995

     Net revenues increased from $89,377 in the 1995 period to $133,161 in the
1996 period. Substantially all of these net revenues arose from the
Partnership's distribution of non-BMS oncology products and from commissions
($4,122 in the 1995 period; $5,544 in the 1996 period) as exclusive sales agent
for BMS oncology products. The increase in revenues (including the increase in
BMS commissions) is attributable principally to a continued increase in product
shipments as a result of increased penetration of existing customer accounts
and, to a lesser degree, an increase in the number of OTN's customers. The
balance of such increases was attributable to increases in the prices of the
oncology products distributed by OTN, which typically reflect a pass-through of
manufacturers' price increases to the Partnership.

     Total costs and expenses, consisting primarily of the cost of revenues,
increased in the 1996 period, as a result of the significant increase in net
revenues. Sales and marketing expense was stable in the 1995 and 1996 periods.
General and administrative expense increased from $4,723 in the 1995 period to
$5,495 in the 1996 period due to a number of factors including increase in
personnel. Total costs and expenses were $85,880 in the 1995 period and $125,893
in the 1996 period representing 96% and 95% of net revenues in the 1995 and the
1996 periods, respectively. Cost of revenues, which represent the principal
component of total costs and expenses, represented 89.5% in the 1995 and 1996
periods.

     Income from operations increased from $3,497 in the 1995 period to $7,268
in the 1996 period. The increase was attributable primarily to the substantial
increase in revenues of the OTN Business for non-BMS oncology products.

     Other income, net and other expense, net were nominal in each period.

     Income before provision for income taxes increased from $3,475 in the 1995
period to $7,247 in the 1996 period. The increase was attributable primarily to
the substantial increase in revenues of the OTN Business for non-BMS oncology
products.

     Net income increased from $3,175 in the 1995 period (after provision for
income taxes at a 9% effective rate, which reflects the remaining benefit of
unrecognized net operating loss carryovers) to $4,422 in the 1996 period (after
provision for income taxes at a 39% effective rate). No further previously
unrecognized net operating loss carryovers were available in 1996, causing the
increase in the effective rate of the income tax provision in the 1996 period.

     Recent Developments

         Axion's preliminary consolidated net revenues for July and August of
1996 have been better than those for recent months, due primarily to the
addition of sales of four new oncology drugs approved by the Food and Drug
Administration in May and June of 1996. Such net revenues are not necessarily
indicative of the results that may

be expected for the full year ending December 31, 1996, and are not intended to
be a projection of future net revenues or trends.
    

Liquidity and Capital Resources

   
     Prior to the formation of the Partnership in July 1993, Axion financed its
operating activities primarily through the issuance of five series of Axion
Preferred Stock, which resulted in an aggregate of $17,248 in net proceeds to
Axion. Axion also had borrowed moderate amounts from time to time under various
bank credit facilities to meet its financing needs. In 1993, Axion increased its
borrowings under its then existing bank credit lines from $1,400 to $3,939 in
connection with increased activities relating to entry into the Partnership, and
then repaid the entire $3,939. Axion operated at a loss through 1993, with a
loss of $3,966 in 1993 increasing the accumulated deficit to $8,709 at December
31, 1993.

     With the formation of the Partnership in July 1993, there was a need for
substantially increased financial resources, including additional borrowing
capacity, both to grow the OTN Business and to finance OTN's receivables with
respect to sales of BMS oncology products under the Sales Agency Agreement.
Under the Sales Agency Agreement, unlike OTN's oncology product distribution
arrangement with other manufacturers, OTN does not purchase oncology products
from BMS for resale. Instead, OTN receives a commission for BMS oncology
products distributed by OTN and, as a result, does not record product revenues
from sales of such products. OTN is responsible for collecting (and financing)
payments from sales of BMS oncology products for up to 180 days, and, within 60
days after shipment, remits to BMS the amount of the receivable for such
shipment less commissions. BMS reimburses OTN for the portion of OTN's financing
costs that relate to the sale of BMS oncology products. BMS ultimately retains
the collection risk of receivables arising from its product sales. See "The
Companies--Axion--Oncology Therapeutics Network--Sales Agency Agreement".

     From August 1993 until September 1994, to facilitate the provision of
credit to OTN customers and to reduce the requirement for other working capital
financing, the Partnership and BMS entered into agreements to sell both BMS and
non-BMS product receivables to GECC, subject to a 25% cash holdback of the
uncollected balance. In September 1994, the arrangement with GECC was
terminated, and BMS provided interim financing under a short-term $30,000
secured note agreement. Also in 1994, Axion received $5,744 in net proceeds
through the issuance of a sixth series of Axion Preferred Stock. In January
1995, the Partnership arranged for a revolving bank credit facility of $50,000,
subject to renewal annually, with borrowings secured by, among other things, the
Partnership's accounts receivable and inventories, its rights under the Sales
Agency Agreement and certain other tangible and intangible collateral. The
$30,000 BMS short-term note was repaid from borrowings under the $50,000
revolving bank credit facility. From January 1995 to date, the ongoing financing
needs of the Partnership have been provided by the $50,000 revolving bank credit
facility. At December 31, 1995, borrowings under the revolving bank credit
facility totaled $35,617. At December 31, 1995 and June 30, 1996, the
Partnership also had available in excess of $14,000 and $9,000, respectively,
which had not been drawn upon under the $50,000 revolving credit line. The
revolving bank credit facility expires December 31, 1996.

     Axion has been profitable since 1994 with net income of $1,428 in 1994,
$7,887 in 1995 and $4,422 in the six months ended June 30, 1996. At December 31,
1995, cash, cash equivalents and short-term investments amounted to $13,522. At
June 30, 1996, these same items amounted to $3,186 reflecting the use of $10,000
during the first quarter for the acquisition of additional OnCare Preferred
Stock. Preference payments received by Axion from the Partnership total
approximately $11,900, including approximately $4,800 in 1995 and $7,100 in the
six months ended June 30, 1996.

                                   THE MERGER

     This section of the Proxy Statement/Prospectus describes certain aspects of
the proposed Merger. To the extent that it relates to the Merger Agreement, the
following description does not purport to be complete and is qualified in its
entirety by reference to the Merger Agreement, which is attached as Appendix A
to this Proxy Statement/Prospectus and is incorporated herein by reference. As
used in this Proxy Statement/Prospectus, the "Retained Company" or the "Retained
Companies", as the case may be, means Axion, together with its subsidiaries,
OTNC, OPUS and the Partnership, which collectively will own and conduct the
Retained Business at the Effective Time. All Axion stockholders are urged to
read the Merger Agreement in its entirety.

Background and Reasons for the Merger; Recommendation of the Axion Board

     Axion's management regularly reviews its current business strategies and
evaluates new opportunities.

     In 1994, Axion determined that there were significant opportunities to
build on its relationships with oncologists to develop a cancer disease
management services business (combined with oncology information services).

   
     In early 1995, certain customers of the OTN oncology drug and related
supplies distribution business (the "OTN Business") reduced their purchases from
OTN due to such customers' perception that a conflict existed between the OTN
Business, on the one hand, and Axion's developing cancer disease management
services business, on the other hand. Concerns about this perceived conflict
were manifested most strongly by oncology physician practice management ("PPM")
groups, who indicated that they viewed Axion as a competitor or potential
competitor.

     As a result, Axion management became increasingly concerned that any
conflict or perceived conflict between the OTN Business and Axion's cancer
disease management services business would prove detrimental to the business and
prospects of OTN. In the third quarter of 1995, the Axion Board instructed
management to consider strategic alternatives to address the conflict issue.

     In October 1995, Axion engaged Alex. Brown & Sons Incorporated ("Alex.
Brown") to assist Axion in exploring and effecting strategic alternatives for
the OTN Business. In consultation with Alex. Brown, Axion management recommended
separating the OTN Business from Axion's other businesses. Three alternatives
for accomplishing this separation were recommended: (1) an initial public
offering of OTNC's common stock; (2) a sale of Axion's interest in OTN to
another company; and (3) a sale of Axion's interest in OTN to its joint venture
partner, BMS. Each of these alternatives would have alleviated the conflict
issue. Axion decided to attempt to move forward simultaneously on each of these
three recommended alternatives in an effort to determine which path would result
in the maximum return to Axion's stockholders. Axion did not consider it
desirable to discontinue its cancer disease management business (principally AHC
and OnCare) in light of the significant investments that Axion had made at that
time in such business and its view of the opportunities associated with such
business.

     As part of the original negotiation and establishment of the Partnership in
1993, BMS and BMOTN were granted certain rights with respect to the management
and operations of the Partnership, as well as certain protections against a
change in control of Axion, OTNC or the Partnership. The change of control
protections contained in the Partnership Agreement and the Sales Agency
Agreement (pursuant to which OTN was appointed by BMS as its exclusive sales
agent for sales of oncology drugs and biologics to U.S. office-based
oncologists) give BMS the right to terminate the OTN Partnership Agreement and
the Sales Agency Agreement in the event of a Change of Control of Axion. A
Change of Control of OTNC or the Partnership is treated under the Sales Agency
Agreement as an assignment requiring BMS's consent, which BMS is entitled to
withhold in its sole discretion. Such an assignment without BMS's consent would
constitute a material breach of the Agreement, and would entitle BMS
    


                                       59

to terminate the Sales Agency Agreement and the Partnership Agreement.
Accordingly, implementation of any of Axion's proposed alternatives to separate
the OTN Business from Axion's other businesses required the consent of BMS. In
October 1995, Axion commenced discussions with BMS regarding the prospect of an
initial public offering of OTNC's common stock or, alternatively, the sale of
Axion's interest in the Partnership.

     In October 1995, Axion and Alex. Brown began preparation of a registration
statement for a public offering of OTNC's common stock. BMS was willing to
consider a public offering of OTNC's common stock only if BMOTN would retain its
existing contractual rights with respect to the management and operations of the
Partnership. Alex. Brown advised Axion that it would be necessary for BMOTN to
give up certain of such existing contractual rights in order to obtain the
desired valuation from public market investors. As a result, Axion concluded,
based upon advice from Alex. Brown, that a public offering was not feasible
under the existing circumstances. The public offering was abandoned in late
1995.

     In December 1995, BMS provided Axion with an oral non-binding indication of
interest with respect to the acquisition of Axion's interest in the Partnership.
Based on discussions with Alex. Brown, Axion concluded that the purchase price
involved was below the value of Axion's interest in the Partnership.

     Concerns related to the perceived conflict between the OTN Business and
Axion's cancer disease management business continued during the second half of
1995, particularly because during that period OnCare progressed from the
development stage to the commencement of operations through the acquisition in
August 1995 of an oncology practice group. As a result, Axion determined to
distribute all its holdings of OnCare common stock to stockholders of Axion,
retaining an interest of $3.5 million in OnCare Preferred Stock. The
distribution was completed effective as of December 31, 1995. In February and
March of 1996, Axion spent an additional $10 million to acquire additional
shares of OnCare Preferred Stock. The perception of a conflict by OTN's
customers continued due to Axion's continuing development of AHC's
cancer-specific managed care services business, Axion's significant economic
stake in OnCare and Axion and OnCare's substantially overlapping stockholders
and senior management.

     In January 1996, on behalf of Axion, Alex. Brown initiated contacts with a
number of potential acquirors of Axion's interest in the Partnership. Over the
next several months, these contacts resulted in preliminary non-binding
indications of interest from several potential third-party acquirors. During the
first and second quarters of 1996, Axion engaged in preliminary discussions, and
exchanged due diligence materials, with several potential third-party acquirors.

     Acquisition discussions also continued in 1996 with BMS. In January 1996,
the discussions with BMS were expanded to include purchasing both Axion's
interest in OTN and the OPUS Station Business.

     On April 1, 1996, BMS made a written non-binding proposal to acquire both
Axion's interest in OTN and the OPUS Station Business on terms significantly
more favorable to Axion and its stockholders than had been previously indicated
by BMS. Negotiations ensued during April and May 1996, during which time Axion
also received other non-binding indications of interest from several potential
third-party acquirors. As discussed above, however, any sale of Axion's interest
in OTN to a third party would have triggered the right of BMS or BMOTN, as
applicable, to terminate the OTN Partnership Agreement and/or the Sales Agency
Agreement, and all proposals received by Axion were made subject to or
predicated on the continuation of the Partnership Agreement and Sales Agency
Agreement. Axion believed that none of the potential third-party acquirors would
be willing to acquire its interest in OTN without the benefit of the existing
contractual arrangements with BMS. During the course of these negotiations, BMS
indicated to Axion that it was BMS's intent to acquire Axion's interest in OTN
and that BMS was not willing to commit that it would not exercise its right to
terminate the Partnership Agreement and Sales Agency Agreement in the event of a
sale of Axion's interest in OTN to a third party unless BMOTN would retain
    


                                       60

its existing negotiated rights with respect to the management and operations of
the Partnership. In late May 1996, BMS again increased its proposed purchase
price and agreed to a transaction structure proposed by Axion designed to make
the proposed sale tax-free to Axion and its stockholders. BMS also agreed to
increase the amount of cash BMS had initially proposed be distributed from the
Partnership to Axion which would be available to fund the development and growth
of the Acquired Business to be distributed to Axion's stockholders. Axion and
BMS entered into a letter of intent on June 20, 1996, and the Merger Agreement
was signed on August 2, 1996. The Amended and Restated Merger Agreement was
signed on September 19, 1996

     In evaluating the proposed Merger, the Axion Board discussed and considered
a variety of factors in order to make a determination of what is in the best
interests of Axion and its stockholders. Specifically, the Axion Board
considered:

          The continuing need to take action to alleviate the perceived conflict
          between the OTN Business and Axion's cancer disease management
          services business (including Axion's continued relationship with and
          interest in OnCare) in order that such conflict not be detrimental to
          the business and prospects of OTN.

          The Axion Board's desire to pursue Axion's cancer disease management
          services business, including Axion's continued relationship with and
          interest in OnCare, particularly in light of the significant
          investments made to date by Axion in this business and the Axion
          Board's view of the opportunities associated with this business.

          The value to be provided to Axion's stockholders as a result of their
          receipt of shares of BMS Common Stock in the Merger, including the
          anticipated tax-free nature of the proposed transaction to Axion's
          stockholders and the liquidity that would be afforded to Axion's
          stockholders by an investment in BMS Common Stock.

          The indemnification obligations that Axion's stockholders would have
          to BMS in connection with the proposed transaction and the limitation
          of such obligations, except in certain limited circumstances, to the
          $5,000,000 of BMS Common Stock to be held in escrow.

         The opportunity for Axion's stockholders to continue to participate on
          an equity basis in the growth and development of the cancer disease
          management services business, including through Axion's interest in
          the OnCare Preferred Stock, as a result of Axion's stockholders'
          receipt of shares of AHC Preferred Stock in the Distribution.

     o    The cash to be provided to AHC in connection with the transaction to
          support AHC's operations and development after giving effect to the
          $5,000,000 in cash to be held in escrow to secure the indemnification
          obligations of Axion's stockholders, AHC and certain of its
          subsidiaries to BMS in connection with the proposed transaction and
          the uncapped nature of certain of those obligations.

     o    The viability of other alternatives or potential transactions in light
          of the terms of the Partnership Agreement and the Sales Agency
          Agreement and the history of Axion's discussions with BMS and other
          potential third-party acquirors, including BMS's willingness to
          consider an initial public offering of OTNC's common stock only if
          BMOTN would retain its existing negotiated rights with respect to the
          management and operations of the Partnership and BMS's expressed
          intent to acquire Axion's interest in OTN and its unwillingness to
          commit that it would not exercise its right to terminate the
          Partnership Agreement and the Sales Agency Agreement in the event of a
          sale of Axion's interest in OTN to a third

          party and the likely unwillingness of third parties to proceed with
          any transaction if the existing contractual arrangements with BMS were
          not in place.

   
     Based on the foregoing, the Axion Board concluded that a sale of its
interest in OTN was necessary to alleviate the ongoing conflict issue and permit
the continued development and growth of its cancer disease management services
business and that the proposed transaction with BMS was the best alternative
available to Axion and its stockholders and represented a fair price to Axion's
stockholders.

     The Axion Board believes that the terms of the Merger are fair to, and in
the best interests of, Axion and Axion's stockholders. The Axion Board has
unanimously approved the Merger Agreement and the transactions contemplated
thereby, including the Merger, and recommends that Axion stockholders vote FOR
approval of the Merger Proposal and that the holders of Axion Preferred Stock
vote FOR approval of the Preferred Stock Proposal.

BMS's Reasons for the Merger

     BMS believes that the separation of the OTN Business from Axion's other
businesses will protect and enhance the value of BMS's existing investment in
the Partnership by eliminating any conflict that may have been perceived by
office-based oncology practices or by PPMs that manage (and control purchasing
for) office-based oncology practices. BMS believes that the acquisition of
Axion's interest in OTN will allow BMS to expand the quality of services
provided by BMS to office-based oncology practices and enhance BMS's core
oncology franchise.

     Conversion of Axion Common Stock in the Merger

   
     At the Effective Time, each issued and outstanding share of Axion Common
Stock (other than any shares of Axion Common Stock owned by Axion or any
subsidiary of Axion or BMS or any wholly owned subsidiary of BMS and any
Dissenting Shares) will be converted into the right to receive the Conversion
Number of fully paid and nonassessable shares of BMS Common Stock (the "Merger
Consideration"). The "Conversion Number" will be equal to the quotient of (a)(i)
$86,000,000 divided by (ii) the Average Value of BMS Common Stock divided by (b)
the number of shares of Axion Common Stock outstanding immediately prior to the
Effective Time (calculated on a fully diluted basis assuming each share of Axion
Preferred Stock outstanding immediately prior to the Effective Time has been
converted in accordance with its terms into one share of Axion Common Stock and
all Axion Options outstanding immediately prior to the Effective Time have been
exercised or canceled and the related subject shares (other than any subject
shares related to any portion of any Axion Option that shall have been canceled
and not exercised) of Axion Common Stock are outstanding (collectively, the
"Diluted Share Assumption")). The term "Average Value of BMS Common Stock" means
an amount equal to the average of the per share closing prices of BMS Common
Stock as reported on the NYSE Tape for the 10 consecutive full NYSE trading days
ending on the fifth full NYSE trading day immediately preceding the Effective
Time; provided that (A) if the BMS Board declares a cash dividend on the
outstanding shares of BMS Common Stock having a record date after the Effective
Time but an ex-dividend Ex-Date that occurs during the averaging period, then
for purposes of computing the Average Value of BMS Common Stock, the closing
price on the Ex-Date and any trading day in the averaging period after the
Ex-Date will be adjusted by adding thereto the amount of such dividend and (B)
if the BMS Board declares a cash dividend on the outstanding shares of BMS
Common Stock having a record date before the Effective Time and an Ex-Date that
occurs during the averaging period, then for purposes of computing the Average
Value of BMS Common Stock, the closing price on any trading day before the
Ex-Date will be adjusted by subtracting therefrom the amount of such dividend.
Notwithstanding anything to the contrary contained in the Merger Agreement, in
the event that as of the Closing Date the Average Value of BMS Common Stock is
less than the Minimum Price ($82.73), then for the purposes of calculating the
Merger Consideration, the Average Value of BMS Common Stock will be deemed to be
the Minimum Price, and in the event that as of the Closing Date the Average
Value of BMS Common Stock is greater than the Maximum Price ($91.43), then for
the purposes of calculating the Merger Consideration, the Average Value of BMS
Common Stock will be deemed to be the Maximum Price. If, prior to the Effective
Time, the BMS Board declares a stock split, stock combination, stock dividend or
other non-cash distribution on the outstanding shares of BMS Common Stock, then
the Minimum Price and Maximum Price (and if the Ex- Date for such event occurs
during the averaging period, the Average Value of BMS Common Stock) will be
appropriately adjusted to reflect such split, combination, dividend or other
distribution.

     Based on the Diluted Share Assumption (and assuming exercise of all Axion
Options other than the Goldberg $10.00 Options (as defined herein), resulting in
an aggregate of 9,970,509 shares of Axion Common Stock outstanding), and
assuming an Average Value of BMS Common Stock equal to $92.83 (the average per
share closing price of BMS Common Stock for the 10 full NYSE trading days ending
September 18, 1996, the most recent full NYSE trading day available prior to
printing this Proxy Statement/Prospectus), in which event the Conversion Number
would be calculated based on an Average Value of BMS Common Stock equal to the
Maximum Price of $91.43, (a) the Conversion Number would be 0.094 and (b)
assuming a market value of the BMS Common Stock on the date received by holders
of Axion Common Stock in the Merger of $92.83, the aggregate market value of BMS
Common Stock to be received by holders of Axion Common Stock in the Merger would
be approximately $87 million, or approximately $8.73 per share of Axion Common
Stock. There can be no assurance that these assumptions will be true as of the
Effective Time.
    


                                       63

     The Average Value of BMS Common Stock is determined as of five full NYSE
trading days immediately preceding the Effective Time (which date may be after
the date of the Special Meeting), at which time the Average Value of BMS Common
Stock may be less than the assumed $92.83 Average Value of BMS Common Stock
referred to above and indeed may be less than the Minimum Price. If the Average
Value of BMS Common Stock at such time is between the Minimum Price ($82.73) and
the Maximum Price ($91.43), the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be $86 million, or
approximately $8.63 per share of Axion Common Stock (based on the Diluted Share
Assumption and assuming exercise of all Axion Options other than the Goldberg
$10.00 Options). If the Average Value of BMS Common Stock at such time is less
than the Minimum Price, the aggregate market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be less, and may be
substantially less, than $86 million, or approximately $8.63 per share of Axion
Common Stock (based on the Diluted Share Assumption and assuming exercise of all
Axion Options other than the Goldberg $10.00 Options). The foregoing statements
in this paragraph assume that the market value of BMS Common Stock on the
Closing Date is equal to the Average Value of the BMS Common Stock used to
calculate the Conversion Number. However, the actual market value of BMS Common
Stock on the Closing Date may be substantially less than the Average Value of
BMS Common Stock used to calculate the Conversion Number. The actual aggregate
market value on the Closing Date of BMS Common Stock received by holders of
Axion Common Stock in the Merger will be equal to the number of shares of BMS
Common Stock issued in the Merger multiplied by the market value of the BMS
Common Stock on the Closing Date.

     Under the terms of the Merger Agreement, Axion does not have the right to
decline to consummate the Merger solely because either the Average Value of BMS
Common Stock used to calculate the Conversion Number is less than the Minimum
Price or because the actual market value of BMS Common Stock on the Closing Date
is less than the Average Value of BMS Common Stock used to calculate the
Conversion Number. Therefore, if the Merger Proposal is adopted and approved and
all other conditions to the Merger are satisfied (or waived by the party for
whose benefit any such condition exists) at or prior to the Effective Time,
Axion stockholders will assume the risk of a decline in the market value of BMS
Common Stock below the Minimum Price and the risk that the actual market value
of BMS Common Stock on the Closing Date is less than the Average Value of BMS
Common Stock used to calculate the Conversion Number and, accordingly, the risk
that the aggregate market value of BMS Common Stock to be received by the
holders of Axion Common Stock in the Merger will be substantially less than $86
million or approximately $8.63 per share (based on the Diluted Share Assumption
and assuming exercise of all Axion Options other than the Goldberg $10.00
Options).

     In addition, the number of assumed outstanding shares of Axion Common Stock
for the purpose of calculating the Conversion Number is determined as of
immediately prior to the Effective Time (which date may be after the date of the
Special Meeting), at which time the actual number of outstanding shares of Axion
Common Stock may be greater than the assumed 9,970,509 shares referred to above.
Each share of Axion Common Stock will be converted in the Merger into the right
to receive the Conversion Number of shares of BMS Common Stock. Any increase in
the actual number of outstanding shares of Axion Common Stock as of immediately
prior to the Effective Time would result in a corresponding decrease in the
Conversion Number and, accordingly, in the number of shares of BMS Common Stock
to be received in respect of each share of Axion Common Stock. The maximum
number of shares of Axion Common Stock that may be outstanding as of immediately
prior to the Effective Time is 10,070,509 shares.

     Cash in Lieu of Fractional Shares

   
     No fractional shares of BMS Common Stock will be issued in the Merger. Each
Axion stockholder who otherwise would have been entitled to receive a fraction
of a share of BMS Common Stock (after taking into account all Certificates (as
defined herein) registered to such holder) will receive, in lieu thereof, cash
(without interest) in an amount, less the amount of any withholding taxes which
may be required thereon, equal to such fractional part of a share of BMS Common
Stock multiplied by the per share closing price of BMS Common Stock as reported
on the NYSE Tape on the full NYSE trading day immediately preceding the Closing
Date.
    

Effective Time; Closing

   
     As soon as practicable following the satisfaction (or waiver by the party
for whose benefit any such condition exists) of the conditions of the Merger
Agreement, BMS, BMS Sub and Axion will file the Certificate of Merger executed
in accordance with the relevant provisions of the DGCL and will make all other
filings or recordings required under the DGCL. The Merger will become effective
and the Effective Time will occur immediately following the Distribution, upon
the filing of the Certificate of Merger with the Delaware Secretary of State or
at such time thereafter as is provided in the Certificate of Merger. The Closing
will take place on a date to be specified by the parties which date will be no
later than the first business day after satisfaction of the conditions to the
Merger Agreement, unless another date is agreed to in writing by BMS, BMS Sub
and Axion.
    

Exchange of Certificates in the Merger

   
     As soon as reasonably practicable after the Effective Time, BMS will cause
the exchange agent to mail to each holder of record of a certificate or
certificates whose shares were converted into the right to receive shares of BMS
Common Stock (i) the Letter of Transmittal and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of BMS Common Stock. Upon surrender of a Certificate for
cancellation to the exchange agent, together with the Letter of Transmittal,
duly executed, and such other documents as may reasonably be required by the
exchange agent, the holder of such Certificate will be entitled to receive in
exchange therefor a certificate representing that number of whole shares of BMS
Common Stock which such holder has the right to receive pursuant to the
provisions of the Merger Agreement (which, for the avoidance of doubt, will not
include the number of shares of BMS Common Stock that will be deemed to have
been deposited in escrow by such holder in accordance with the provisions of the
Merger Agreement), and the surrendered Certificate will be canceled. AXION
STOCKHOLDERS ARE REQUESTED NOT TO SURRENDER THEIR CERTIFICATES REPRESENTING
OUTSTANDING SHARES OF AXION COMMON STOCK FOR EXCHANGE UNTIL THEY RECEIVE A
LETTER OF TRANSMITTAL FROM BMS. EXECUTION AND DELIVERY OF THE LETTER OF
TRANSMITTAL BY EACH FORMER AXION STOCKHOLDER WILL RESULT IN EACH SUCH FORMER
AXION STOCKHOLDER BECOMING A PARTY TO AND BOUND BY THE INDEMNIFICATION
AGREEMENT, THE TAX MATTERS AGREEMENT AND THE ESCROW AGREEMENT AND WILL RESULT IN
THE IRREVOCABLE APPOINTMENT OF AHC AS EACH SUCH FORMER AXION STOCKHOLDER'S AGENT
AND ATTORNEY-IN-FACT TO TAKE ANY AND ALL ACTIONS ON BEHALF OF EACH SUCH FORMER
AXION STOCKHOLDER THAT MAY BE NECESSARY IN CONNECTION WITH THE TRANSACTIONS
CONTEMPLATED BY SUCH AGREEMENTS. SEE "--INDEMNIFICATION ARRANGEMENTS; ESCROW;
APPOINTMENT OF AHC AS REPRESENTATIVE".

     In the event of a transfer of ownership of Axion Common Stock which is not
registered in the transfer records of Axion, a certificate representing the
proper number of shares of BMS Common Stock may be issued
    


                                       65

to a person other than the person in whose name the Certificate so surrendered
is registered, if such Certificate shall be properly endorsed or otherwise be in
proper form for transfer and the person requesting such payment shall pay any
transfer or other taxes required by reason of the issuance of shares of BMS
Common Stock to a person other than the registered holder of such Certificate or
establish to the satisfaction of BMS that such tax has been paid or is not
applicable. Until surrendered, each Certificate will be deemed at any time after
the Effective Time to represent only the right to receive upon surrender the
certificate representing shares of BMS Common Stock and cash in lieu of any
fractional shares of BMS Common Stock. No interest will be paid or will accrue
on any cash payable in lieu of any fractional shares of BMS Common Stock.
    

     No dividends or other distributions with respect to BMS Common Stock with a
record date after the Effective Time will be paid to the holder of any
unsurrendered Certificate with respect to the shares of BMS Common Stock
represented thereby, and no cash payment in lieu of fractional shares will be
paid to any such holder until the surrender of such Certificate in accordance
with the provisions of the Merger Agreement. Following surrender of any such
Certificate, there will be paid to the holder of the Certificate representing
whole shares of BMS Common Stock issued in exchange therefor, without interest,
(i) at the time of such surrender, the amount of cash payable in lieu of any
fractional shares of BMS Common Stock to which such holder is entitled and the
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of BMS Common
Stock, less the amount of any withholding taxes which may be required thereon,
and (ii) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to such
surrender and a payment date subsequent to such surrender payable with respect
to such whole shares of BMS Common Stock, less the amount of any withholding
taxes which may be required thereon.

   
     There may be deducted and withheld from the consideration otherwise payable
pursuant to the Merger Agreement to any holder of Axion Common Stock such
amounts as may be required to be deducted and withheld with respect to the
making of such payment under the Code, or under any provision of state, local or
foreign tax law. To the extent that amounts are so withheld and paid over to the
appropriate taxing authority, such withheld amounts shall be treated for all
purposes of the Merger Agreement as having been paid to the holder of Axion
Common Stock in respect of which such deduction and withholding was made.

      See "Risk Factors--Indemnification Obligations of the Former Axion
Stockholders, AHC and the 81% AHC Subsidiaries" for a discussion of certain
other matters relating to the Letter of Transmittal.
    

     After the Effective Time, there will be no further transfers on the stock
transfer books of Axion.

Indemnification Arrangements; Escrow; Appointment of AHC as Representative

   
     Execution and delivery of the Letter of Transmittal by each Former Axion
Stockholder will result in each such Former Axion Stockholder irrevocably
appointing AHC as his/her or its agent and attorney-in-fact to execute and
deliver on such Former Axion Stockholder's behalf, and thereby result in each
such Former Axion Stockholder becoming a party to and bound by, the
Indemnification Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution and delivery of the Letter of Transmittal will result in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder that may be necessary in connection with the transactions
contemplated by such agreements, including to give and receive notices on each
such Former Axion Stockholder's behalf and to represent each such Former Axion
Stockholder with respect to any matter, suit, claim, action or proceeding
arising with respect to any transaction contemplated by such agreements,
including the defense, appeal or settlement of any claim, action or proceeding
for which
    


                                       66




<PAGE>
 

<PAGE>



   
each such former Axion Stockholder may be obligated to indemnify any person
pursuant to such agreements or may be entitled to indemnification pursuant to
such agreements or which may be brought by BMS against each such Former Axion
Stockholder to enforce such indemnity; and will result in each such Former Axion
Stockholder ratifying and confirming any action taken by AHC in the exercise of
the power of attorney granted thereby. See "Risk Factors--Indemnification
Obligations of the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries".
Immediately following the Effective Time the Escrowed Shares and the Escrowed
Cash will be placed in escrow to secure certain obligations of such Former Axion
Stockholders and AHC and certain of its subsidiaries to indemnify BMS and its
subsidiaries. There can be no assurance as to whether all or any portion of such
Escrowed Shares will eventually be released to such Former Axion Stockholders or
as to whether all or any portion of such Escrowed Cash will eventually be
released to AHC. See "Indemnification Arrangements--Terms of the Indemnification
Agreement"; "--Terms of the Tax Matters Agreement"; and "--Terms of the Escrow
Agreement".

Covenants

     Ordinary Conduct of Axion and its Subsidiaries

   
     Pursuant to the Merger Agreement, Axion has agreed that during the period
from the date of the Merger Agreement until the Effective Time, except for the
Contributions, the Distribution, the Merger and the other transactions expressly
provided for in the Documents, as expressly contemplated or permitted by the
Merger Agreement or to the extent that BMS otherwise consents in writing (it
being understood that BMS shall be deemed to have consented to any action or
failure to act that would constitute a breach of any of the covenants described
below if and to the extent such action or failure to act was taken pursuant to
the express written direction of the Deciding Member (as defined in the First
Amendment dated as of August 2, 1996 to the Partnership Agreement) in accordance
with the provisions of Section 7.7 of the Partnership Agreement, as amended)
with such consent to be within BMS's sole discretion:
    

          (a) Axion and its subsidiaries will each carry on their respective
     businesses in the usual, regular and ordinary course in substantially the
     same manner as presently conducted consistent with past practice and will
     make all reasonable best efforts to preserve intact their current business
     organizations, keep available the services of their current officers and
     employees and preserve their relationships with customers, suppliers,
     licensors, licensees, distributors and others having business dealings with
     the Retained Business with the goal that the goodwill and ongoing
     businesses of the Retained Business will be unimpaired at the Effective
     Time, it being understood that the failure of any employee of the Retained
     Company to be an employee of the Retained Company or its subsidiaries at
     the Effective Time (other than James W. Adams, Michael B. Cunningham,
     Warren M. Dodge, Lynn B. Hammerschmidt and David L. Levison) will not
     constitute a breach of this covenant; provided, that no employee of the
     Retained Company may be terminated by Axion or any of its subsidiaries
     prior to the Effective Time except with cause or with the prior written
     consent of BMS which consent will not be unreasonably withheld; provided
     further, that the satisfaction of any Pre-JV Sales Taxes and JV Sales Taxes
     (each such term as defined in the Tax Matters Agreement) will not
     constitute a breach of this covenant. Axion, its subsidiaries and their
     respective directors, officers or employees will each continue to use their
     respective reasonable best efforts to promote the interests of Axion and
     its subsidiaries, and Axion will not, nor will it permit any of its
     subsidiaries or any of their respective directors, officers or employees
     to, take any action that would conflict with the business of Axion or any
     of its subsidiaries or that would have or could reasonably be expected to
     have, a Retained Company Material Adverse Effect or an AHC Material Adverse
     Effect.

          (b) Axion will not, nor will it permit any of its subsidiaries to, (i)
     split, combine or reclassify any of its capital stock or issue or authorize
     the issuance of any other securities in respect of, in lieu of or in
     substitution for shares of its capital stock; (ii) repurchase, redeem or
     otherwise acquire any shares of capital stock of Axion or any of its
     subsidiaries or any other securities thereof or any rights, warrants or
     options to acquire any such shares or other securities except as disclosed
     in the schedules to the Merger Agreement; (iii) transfer or sell, or
     authorize or propose or agree to the issuance, transfer or sale by Axion or
     any such subsidiary of any shares of its capital stock of any class or
     other equity interests, any other voting securities or any securities
     convertible into or exchangeable for, or any rights, warrants or options to
     acquire, any such shares, voting securities or convertible or exchangeable
     securities, other than the issuance, transfer, sale or disposition of Axion
     Common Stock upon the exercise of Axion Options outstanding as of the date
     of the Merger Agreement in accordance with their terms on the date of the
     Merger Agreement or (iv) issue, declare, set aside, make or pay any
     dividends on or other distributions with respect to its capital stock.

     Company or any of its subsidiaries as of the date of the Merger Agreement
     or (ii) AHC or any of its subsidiaries as of the date of the Merger
     Agreement that would, based on the facts and circumstances and conduct of
     the particular business, materially increase the potential liability of the
     Retained Company or any of its subsidiaries under statutes or legal
     doctrines permitting the imposition of liability on a parent corporation in
     respect of the liabilities of its subsidiaries.

   
          (e) Axion will not, nor will it permit any of its subsidiaries to, (i)
     acquire (A) by merging or consolidating with, or by purchasing a
     substantial portion of the assets of, or by any other manner, any business
     or any corporation, partnership, joint venture, association or other
     business organization or division thereof or (B) any material assets except
     as provided in paragraph (h) below or purchases of inventory in the
     ordinary course of business consistent with past practice or (ii) make or
     agree to make any other investment in any person (whether by means of loan,
     capital contribution, purchase of capital stock, obligations or other
     securities, purchase of all or any integral part of the business of the
     person or any commitment or option to make an investment or otherwise)
     (other than loans to Axion employees to fund the purchase of Axion Common
     Stock in connection with the exercise of such employee's respective Axion
     Options).
    

          (f) Axion will not, nor will it permit any of its subsidiaries to,
     sell, lease, license or otherwise dispose of any of its material assets,
     except sales of inventory in the ordinary course of business consistent

     subsidiaries, guarantee any debt securities of another person, enter into
     any "keep well" or other agreement to maintain any financial statement
     condition of another person or enter into any arrangement having the
     economic effect of any of the foregoing, except for short-term borrowings
     incurred in the ordinary course of business consistent with past practice
     under the Loan Agreement dated as of December 2, 1994, between Bank of
     America National Trust and Savings Association and the Partnership, as
     amended (the "Loan Agreement"), (ii) permit, allow or suffer to exist any
     mortgage, lien, encumbrance, easement, covenant, right-of-way or other
     similar restriction of any nature whatsoever which would have been required
     to be set forth in schedules to the Merger Agreement if existing on the
     date of the Merger Agreement or (iii) cancel any material indebtedness
     (individually or in the aggregate) or waive any claims or rights of
     substantial value.

          (h) Axion will not, nor will it permit any of its subsidiaries to,
     make or agree to make any capital expenditure or expenditures which, in the
     aggregate, are in excess of $3,000,000 other than capital expenditures that
     will constitute part of the Acquired Assets.

     grant to any executive officer or employee any increase in compensation or

     grant an executive officer or employee of AHC an increase in compensation
     (but not


                                       70




<PAGE>
 

<PAGE>



     including benefits) so long as immediately following the Effective Time
     neither the Retained Company nor any of its subsidiaries has any direct or
     indirect liability whatsoever resulting from such change or increase.

          (j) Axion will not, nor will it permit any of its subsidiaries to,
     change any of its accounting principles, practices, policies or procedures,

     Additional Covenants of Axion

     Pursuant to the Merger Agreement, Axion has agreed as to itself and its
subsidiaries that, except as expressly provided for in the Documents, during the
period from the date of the Merger Agreement and continuing to the Effective
Time:

          (a) Notwithstanding the fact that such action might otherwise be
     permitted pursuant to the Merger Agreement, Axion will not, nor will it
     permit any of its subsidiaries to, take any action that would or is
     reasonably likely to result in (i) any of the conditions to the Merger set
     forth in the Merger Agreement not being satisfied, (ii) any of the
     representations and warranties of Axion set forth in the Merger Agreement
     that are qualified as to materiality becoming untrue or (iii) any of such
     representations and warranties that


                                       71




<PAGE>
 

<PAGE>



     are not so qualified becoming untrue in any material respect, or that would
     materially impair the ability of Axion to consummate the Contributions or
     the Distribution in accordance with the terms of the Distribution Agreement
     or the Merger in accordance with the terms of the Merger Agreement or would
     materially delay such consummation or that would, to the knowledge of
     Axion, disqualify the Distribution as a tax-free spinoff within the meaning
     of Section 355 of the Code or disqualify the Merger as a tax-free
     reorganization under Section 368(1)(B) of the Code.

          (b) Axion will (i) not engage in or allow transfers of assets or
     liabilities or engage or enter into other transactions between (A) the
     Retained Company and its subsidiaries, on the one hand, and (B)(I) AHC and
     its subsidiaries, (II) OnCare and its subsidiaries or (III) any affiliate
     of AHC or OnCare, on the other hand, except as expressly contemplated by
     the Merger Agreement and by the other Documents, (ii) abide and cause AHC
     and its subsidiaries to abide by their respective obligations under the
     Documents and (iii) not terminate or amend, or waive compliance with any
     obligations under, the Documents (other than the waiver by Axion of the
     conditions to its obligations to close under the Merger Agreement and other
     than by termination of the Merger Agreement by Axion in accordance with
     certain provisions of the Merger Agreement) without the consent of BMS
     which consent can be withheld in its sole discretion.

   
          (c) Axion will promptly advise BMS orally and in writing of any change
     or development or combination of changes or developments that would cause
     the representation with respect to the absence of certain changes or events
     to be untrue. Axion will promptly provide BMS (or its counsel) copies of
     all filings made by Axion with any Federal, state or foreign Governmental
     Entity in connection with the Documents and the transactions contemplated
     by the Merger Agreement and the other Documents.
    

          (d) Axion will keep, or cause to be kept, all insurance policies set
     forth in the schedules to the Merger Agreement, or suitable replacements
     therefor, in full force and effect through the close of business on the
     Closing Date. Axion will, and will cause its subsidiaries to, use its
     reasonable best efforts to renew the insurance policies set forth in the
     schedules to the Merger Agreement, or suitable replacements therefor,
     maintained with respect to Axion and its subsidiaries and their respective
     assets and properties upon expiration or termination of such policies on a
     month-to-month basis.

          (e) On the Closing Date, Axion will cause to be delivered to BMS duly
     signed resignations (from the applicable board of directors), effective
     immediately after the Closing, of all directors of the Retained Company and
     each of its subsidiaries and will take such other action as is necessary to
     accomplish the foregoing.

          (f) (i) From the date of the Merger Agreement through the Closing,
     Axion will give prompt notice to BMS of (A) the occurrence, or failure to
     occur, of any event which occurrence or failure would be likely to cause
     any representation or warranty contained in the Merger Agreement or any
     other Document to be untrue or inaccurate in any material respect and (B)
     any material failure of Axion or any of its subsidiaries or affiliates, or
     of any of its stockholders or holders of Axion Options, to comply with or
     satisfy any covenant, condition or agreement to be complied with or
     satisfied by it under the Merger Agreement or any other Document; provided,
     however, that such disclosure will not be deemed to cure any breach of a
     representation, warranty, covenant or agreement or to satisfy any
     condition. Axion will promptly notify BMS of any default, the threat or
     commencement of any action, or any development that occurs before the
     Closing that could in any way materially affect the Retained Business, the
     Retained Company and its subsidiaries or AHC and its subsidiaries. Axion
     will have the continuing obligation until the Closing to supplement or
     amend the schedules to the Merger Agreement on a monthly basis with the
     final supplement or amendment to such schedules to occur not later than two
     business days prior to the Closing.

          (ii) Axion will promptly notify BMS of and furnish BMS any information
     it may reasonably request with respect to, the occurrence to Axion's actual
     knowledge of any event or condition or the existence to Axion's actual
     knowledge of any fact that would cause any of the conditions to BMS's
     obligation to consummate the Merger and the other transactions contemplated
     by the Merger Agreement not to be fulfilled.

          (g) (i) Axion will, and will direct and use its best efforts to cause
     its officers, directors, employees, representatives and agents to,
     immediately cease any discussions or negotiations with any parties that may
     be ongoing with respect to an Acquisition Proposal (as defined below).
     Axion will not, nor will it permit any of its subsidiaries to, nor will it
     authorize or permit any of its officers, directors or employees or any
     investment banker, financial advisor, attorney, accountant or other
     representative retained by it or any of its subsidiaries to, directly or
     indirectly, (A) solicit, initiate or knowingly encourage (including by way
     of furnishing information), or take any other action designed or reasonably
     likely to facilitate, any inquiries or the making of any proposal which
     constitutes, or may reasonably be expected to lead to, any Acquisition
     Proposal or (B) participate in any discussions or negotiations regarding
     any Acquisition Proposal. Without limiting the foregoing, it is understood
     that any violation of the restrictions set forth in the preceding sentence
     by any director or executive officer of Axion or any of its subsidiaries,
     whether or not such person is purporting to act on behalf of Axion or any
     of its subsidiaries or otherwise, will be deemed to be a breach of this
     covenant by Axion. For purposes of the Merger Agreement, "Acquisition
     Proposal" means any inquiry, proposal or offer from any person with respect
     to a merger, acquisition, consolidation or similar transaction involving,
     or any purchase of all or any significant portion of the assets or any
     equity securities of, the Retained Business, other than the transactions
     contemplated by the Merger Agreement, or any other transaction the
     consummation of which could reasonably be expected to impede, interfere
     with, prevent or materially delay the Merger or which would reasonably be
     expected to dilute materially the benefits to BMS of the transactions
     contemplated by the Merger Agreement and the other Documents.

          (ii) Neither the Axion Board nor any committee thereof will (A)
     withdraw or modify, or propose publicly to withdraw or modify, in a manner
     adverse to BMS, the approval or recommendation by such Board or such
     committee of the Merger or the Merger Agreement, (B) approve or recommend,
     or propose publicly to approve or recommend, any Acquisition Proposal or
     (C) cause Axion to enter into any letter of intent, agreement in principle,
     acquisition agreement or other similar agreement related to any Acquisition
     Proposal.

          (iii) In addition to the obligations of Axion set forth in paragraphs
     (i) and (ii) above, Axion will immediately advise BMS orally and in writing
     of any request for information or of any Acquisition Proposal, the material
     terms and conditions of such request or Acquisition Proposal and the
     identity of the person making such request or Acquisition Proposal. Axion
     will keep BMS fully informed of the status and details (including
     amendments or proposed amendments) of any such request or Acquisition
     Proposal.

     Covenants of BMS

     During the period from the date of the Merger Agreement and continuing to
the Effective Time, BMS agrees as to itself and its subsidiaries, except to the
extent that Axion otherwise consents in writing with such consent to be within
Axion's sole discretion, that, notwithstanding the fact that such action might
otherwise be permitted pursuant to the Merger Agreement, BMS will not, nor will
it permit any of its subsidiaries to, take any action that would or could
reasonably be likely to result in (i) any of the conditions to the Merger set
forth in the Merger Agreement not being satisfied, (ii) any of the
representations and warranties of BMS set forth in the Merger Agreement that are
qualified as to materiality becoming untrue or (iii) any of such representations


                                       73

and warranties that are not so qualified becoming untrue in any material respect
or materially impairing the ability of BMS to consummate the Merger in
accordance with the terms of the Merger Agreement.

   
     Other Agreements of BMS and Axion

     Each of BMS and Axion will, subject to certain conditions, use its
reasonable best efforts to cause the Closing to occur and will use its
reasonable best efforts to cause the Closing to occur by September 30, 1996.

fully vested, and all such Axion Options shall have been exercised or canceled.
No Axion Options shall be assumed by the Surviving Corporation.

     As of the date of the Merger Agreement, BMS and Axion caused the OTN
Partnership Agreement to be amended. See "The Companies--Axion--Oncology

enter into (or cause to be entered into) separate agreements for each of the

     outstanding any indebtedness for borrowed money, or any guarantees in

Sub and Axion; (b) by either BMS or Axion: (i) if, upon a vote at the Special
Meeting or any adjournment thereof, any required approval of the Axion
stockholders will not have been obtained; (ii) if the Merger will not have been
consummated on or before October 31, 1996, unless the failure to consummate the
Merger is the result of a wilful and material breach of the Merger Agreement by
the party seeking to terminate the Merger Agreement; provided, however, that the
passage of such period will be tolled for any part thereof (but in no event
beyond December 31, 1996) during which any party will be subject to a nonfinal
order, decree, ruling or action restraining, enjoining or otherwise prohibiting
the consummation of the Merger or the calling or holding of the Special Meeting;
or (iii) if any governmental entity will have issued an order, decree or ruling
or taken any other action permanently enjoining, restraining or otherwise
prohibiting the Merger and such order, decree, ruling or other action will have
become final and nonappealable; (c) by Axion if BMS or BMS Sub will have failed
to comply in any material respect with any of the covenants or agreements
contained in the Merger Agreement or any other Document to be performed by BMS
or BMS Sub at or prior to the time of termination, which breach will not have
been cured within 30 days following written notice of such breach; or (d) by BMS
if Axion or any of its subsidiaries will have failed to comply in any material
respect with any of the covenants or agreements contained in the Merger
Agreement or any other Document to be performed by Axion or any of its
subsidiaries at or prior to the time of termination, which breach will not have
been cured within 30 days following written notice of such breach.

     Effect of Termination

     In the event of termination of the Merger Agreement by either Axion or BMS
as described in "--Termination", the Merger Agreement will forthwith become void
and have no effect, and, except for certain obligations provided for in the
Merger Agreement which will survive termination, there will be no liability or
obligation on the part of BMS, BMS Sub or Axion, except to the extent that such
termination results from the wilful and material breach by a party of any of its
representations, warranties, covenants or agreements set forth in the Merger
Agreement, the Distribution Agreement or any agreement contemplated thereby.

     Amendment

     The Merger Agreement may be amended by the parties at any time before or
after any required approval of matters presented in connection with the Merger
by the stockholders of Axion; provided, however, that after any such approval,
there will be made no amendment that by law requires further approval by such
stockholders without the further approval of such stockholders. The Merger
Agreement may not be amended except by an instrument in writing signed on behalf
of each of the parties.

Expenses

     The Merger Agreement provides that (except as provided below) whether or
not the Merger is consummated, all out-of-pocket fees and expenses incurred in
connection with the Merger, the Distribution or the consummation of any of the
transactions contemplated by the Merger Agreement and the Documents and the
negotiation, preparation, review and delivery of the agreements contemplated
thereby, including all fees and expenses of accountants, legal counsel,
investment bankers and other advisors will be paid by the party incurring such
fees or expenses, except that expenses incurred in connection with printing and
mailing this Proxy Statement/Prospectus and the Form S-4 will be shared equally
by BMS and Axion. Expenses incurred in connection with the Required AHC
Documents will be paid by Axion.
   
     At the Closing, BMS will provide, or cause to be provided, to Axion funds
in an amount equal to the lesser of $2,000,000 and the aggregate amount of Axion
Expenses set forth in a true and complete schedule to be submitted by Axion to
BMS not later than five business days prior to Closing (the "Transaction Expense
Schedule"), and Axion will pay the Axion Expenses listed in such schedule. The
term "Axion Expenses" means all out-of-pocket fees and expenses incurred or to
be incurred by or on behalf of Axion or any of its subsidiaries in connection
with the Merger, the Distribution or the consummation of any of the transactions
contemplated by the Merger Agreement and the other Documents and the
negotiation, preparation, review and delivery of the Merger Agreement and the
agreements contemplated thereby and by the other Documents, including all
Axion's expenses incurred or to be incurred by Axion or any such subsidiary in
connection with printing and mailing the documents filed or required to be filed
by AHC (including the Information Statement) with the Commission or any state
securities commission or otherwise required to be provided or delivered to the
stockholders of Axion or, following the Distribution, AHC, in connection with
the distribution of shares of AHC Preferred Stock in connection with the
Distribution (collectively, the "Required AHC Documents") other than the Proxy
Statement and, subject to certain provisions of the Merger Agreement, this Proxy
Statement/Prospectus and the Form S-4 and all fees and expenses incurred or to
be incurred by Axion or any such subsidiary of accountants, legal counsel,
investment bankers and other advisors. The term "Excess Axion Expenses" means
all Axion Expenses in excess of $2,000,000.

     The Merger will be accounted for by BMS as a "purchase" for financial
accounting purposes in accordance with GAAP. The purchase price (i.e., the
Merger Consideration) will be allocated based on the fair values of assets
acquired and liabilities assumed.

Interests of Certain Persons in the Transactions

     In considering the recommendations of the Axion Board, Axion stockholders
should be aware that Axion's officers and members of the Axion Board will have
certain interests in the Distribution and the Merger as a result of their status
as stockholders plus certain interests in addition to the interests of
stockholders generally.
   
     The Merger will constitute a "corporate transaction" of Axion with respect
to all Axion Options outstanding under the Axion 1989 Stock Option and
Restricted Stock Plan (the "Axion 1989 Plan") and 1995 Executive Stock Option
Plan (the "Axion 1995 Plan"). See "Effect of Transactions on Axion Employees and
Axion Benefit Plans". In addition, as noted above, pursuant to the Merger
Agreement all Axion Options outstanding prior to the Time of Contribution shall
be vested, and will be exercised or canceled. Accordingly, the authorization and
adoption of the Merger Agreement by Axion stockholders will, if the Merger is
consummated, have the following consequences with respect to such Axion Options:

     (a)  all such Axion Options that had not previously become exercisable and
          vested will become fully exercisable and vested in connection with the
          Merger;

     (b)  Axion will extend loans to each executive officer, in addition to each
          current employee or consultant, to enable such individual to exercise
          in full his or her Axion Options; and

     (c)  each officer, employee or consultant who exercises his or her Axion
          Options will receive in exchange for his or her Axion Common Stock in
          the Merger shares of BMS Common Stock, which stock will be freely
          tradable immediately following the consummation of the Merger, subject
          to contractual restrictions on the officer's ability to resell the BMS
          Common Stock and the limitations set forth under Rule 145 under the
          Securities Act.

     As of the Record Date, options to purchase a total of 1,697,968 shares of
Axion Common Stock, at exercise prices ranging from $0.075 to $10.00 per share,
were held by 91 Axion employees, directors and consultants. Of the options so
held, options to purchase a total of 799,544 shares at prices ranging from
$0.075 to $10.00 per share were unvested at the Record Date, and will become
vested in connection with the Merger. Michael D. Goldberg, the President and
Chief Executive Officer of Axion, has advised Axion that he does not intend to
exercise the Goldberg $10.00 Options, which, accordingly, will be canceled prior
to the Time of Contribution.

     Set forth below is a table showing, for certain of Axion's officers, the
total number of shares subject to options (vested and unvested) held by the
officer as of the Record Date, the range of exercise prices under such options
and the number of option shares that will become vested as a result of the
Merger. See "Security Ownership of Certain Beneficial Owners and Management of
Axion" herein and "Management" and "Security Ownership of Certain Beneficial
Owners and Management of AHC" in the Information Statement attached hereto as
Appendix G.

(1) Options exercisable into 30,000 shares held by Galen Associates, a Delaware
limited partnership, and options exercisable into 2,500 shares held by Longbow
Partners, a New York general partnership. Dr. Wilkerson, a director of Axion, is
also a controlling stockholder of two corporations that are general partners of
Galen Associates. Dr. Wilkerson disclaims beneficial ownership of the options
held by Galen Associates except to the extent of his pecuniary interest therein
arising from his interests as a stockholder in the corporations that are general
partners of Galen Associates. Dr. Wilkerson is a general partner of Longbow
Partners and disclaims beneficial ownership of the options held by Longbow
Partners except to the extent of his pecuniary interest therein.

   
     It is anticipated that Axion will extend the Employee Loans totaling
approximately $6,500,000 to approximately 91 holders of Axion Options, who will
use the proceeds to exercise such Axion Options immediately prior to the Time of
Contribution. Axion will loan a sum of money to each such holder equal to the
exercise price for all of the shares purchasable under each such optionee's
respective Axion Options, the proceeds of which such optionee may use to
exercise his or her Axion Options. Each such note shall be full recourse, may be
secured or unsecured, shall bear interest at the applicable Federal rate
established by the IRS and shall be due at the end of two years, subject to
acceleration to the extent the optionee sells any of the Axion shares purchased
with the note (other than in the Merger) or the BMS shares received in exchange
for such Axion shares.
    
     In addition, OTNC has entered into employment agreements with certain
employees, which agreements will become effective at the Effective Time. Axion
has also adopted a severance plan applicable to certain employees of OTNC. See
"Effect of Transactions on Axion Employees and Axion Benefit Plans".
   
     Axion has entered into separate indemnification agreements with its
directors and officers. These agreements require Axion, among other things, to
indemnify its directors and officers against certain liabilities that may arise
by reason of their status or service as directors or officers (other than
liabilities arising from actions not taken in good faith or in a manner the
indemnitee believed to be in the best interests of Axion) and to advance their
expenses incurred as a result of any proceeding against them as to which they
could be indemnified. The Axion Certificate of Incorporation also provides for
exculpation of directors under certain circumstances. See "Comparison of Certain
Rights of Holders of BMS Common Stock, Holders of Axion Common Stock and Holders
of Axion Preferred Stock--Indemnification of Officers and Directors". In
addition, it is anticipated that AHC will enter into similar indemnification
agreements with its directors and officers, and that the AHC certificate of
incorporation and by-laws will provide, as applicable, for the indemnification
of directors and officers and the exculpation under certain circumstances of
directors. See "Executive

Resales of BMS Common Stock Issued in the Merger; Affiliates

     The BMS Common Stock to be issued to Axion stockholders in connection with
the Merger will be freely transferable under the Securities Act, except for
shares issued to any person who may be deemed an "affiliate" of Axion or BMS
within the meaning of Rule 145 under the Securities Act. In the Merger
Agreement, Axion has agreed to use its reasonable best efforts to cause each of
those persons who may be deemed affiliates of Axion to deliver to BMS on or
prior to the Closing Date a written agreement providing that such persons will
not make any sale, transfer or other disposition of the BMS Common Stock
received in connection with the Merger in violation of the Securities Act or the
rules and regulations promulgated thereunder. If any affiliate refuses to
provide such an agreement, BMS will be entitled to place appropriate legends on
the BMS shares to be received by such affiliates, and to issue stop transfer
instructions to BMS's transfer agent in regard to such shares. This Proxy
Statement/Prospectus does not cover any resales of BMS Common Stock received by
affiliates of BMS, including certain family members and related interests.

Dissenters' Rights

     Holders of shares of Axion Common Stock are entitled to appraisal rights
under Section 262, provided that they comply with the conditions established by
Section 262. Section 262 is reprinted in its entirety as Appendix F to this
Proxy Statement/Prospectus. The following discussion is not a complete statement
of the law relating to appraisal rights and is qualified in its entirety by
reference to Appendix F. This discussion and Appendix F should be reviewed
carefully by any Axion stockholder who wishes to exercise statutory appraisal
rights or who wishes to preserve the right to do so, since failure to comply
with the procedures set forth herein or therein will result in the loss of
appraisal rights.

     Axion stockholders of record who desire to exercise their appraisal rights
must:

     -    hold shares of Axion Common Stock on the date of making a demand for
          appraisal;

     -    make a written demand for appraisal prior to the vote on the Merger by
          Axion stockholders;

     -    continuously hold such shares through the Effective Time;

     -    not vote in favor of the Merger nor consent thereto in writing;

     -    file any necessary petition in the Delaware Court of Chancery (the
          "Delaware Court"), as more fully described below, within 120 days
          after the Effective Time; and

     -    otherwise satisfy all of the conditions described more fully below.

     A record holder of shares of Axion Common Stock who makes the demand
described below with respect to such shares (the "Dissenting Shares"), who
continuously is the record holder of such shares through the Effective Time, who
otherwise complies with the statutory requirements of Section 262 and who
neither votes in favor of the Merger nor consents thereto in writing will be
entitled to an appraisal by the Delaware Court of the fair value of his shares
of Axion Common Stock. All references in Section 262 and in this summary of
appraisal

<PAGE>



rights to an "Axion stockholder" or "holders" of shares are to the record holder
or holders of shares of Axion Common Stock.

     Holders of shares of Axion Common Stock who desire to exercise their
appraisal rights must not vote in favor of the Merger and must deliver a
separate written demand for appraisal to Axion prior to the vote by the Axion
stockholders on the Merger. A demand for appraisal must be executed by or on
behalf of the holder of record, fully and correctly, as such holder's name
appears on the certificate or certificates representing shares of Axion Common
Stock. A person having a beneficial interest in shares of Axion Common Stock
that are held of record in the name of another person, such as a broker,
fiduciary or other nominee, must act promptly, to cause the record holder to
follow the steps summarized herein properly and in a timely manner to perfect
whatever appraisal rights are available. If shares of Axion Common Stock are
owned of record by a person other than the beneficial owner, including a broker,
fiduciary (such as a trustee, guardian or custodian) or other nominee, such
demand must be executed by or for the record owner. If shares of Axion Common
Stock are owned of record by more than one person, as in a joint tenancy or
tenancy in common, such demand must be executed by or for all joint owners. An
authorized agent, including an agent for two or more joint owners, may execute
the demand for appraisal for a stockholder of record; however, the agent must
identify the record owner and expressly disclose the fact that, in exercising
the demand, such person is acting as agent for the record owner.

     A record owner, such as a broker, fiduciary or other nominee, who holds
shares of Axion Common Stock as a nominee for others, may exercise appraisal
rights with respect to the shares held for all or less than all beneficial
owners of shares as to which such person is the record owner. In such case, the
written demand must set forth the number of shares covered by such demand. Where
the number of shares is not expressly stated, the demand will be presumed to
cover all shares of Axion Common Stock outstanding in the name of such record
owner.

     An Axion stockholder who elects to exercise appraisal rights should mail or
deliver his or her written demand to: Gunderson Dettmer Stough Villeneuve
Franklin & Hachigian, LLP, 600 Hansen Way, Second Floor, Palo Alto, CA 94304,
Attention: Steven M. Spurlock, Esq. The written demand for appraisal should
specify the Axion stockholder's name and mailing address, the number of shares
of Axion Common Stock owned, and that the holder is thereby demanding appraisal
of his or her shares. A proxy or vote against the Merger will not constitute
such a demand. Within ten days after the Effective Time, the Surviving
Corporation must provide notice of the Effective Time to all holders who have
complied with Section 262.

     Within 120 days after the Effective Time, either Axion, as the Surviving
Corporation, or any holder who has complied with the required conditions of
Section 262, may file a petition in the Delaware Court, with a copy served on
the Surviving Corporation in the case of a petition filed by a holder, demanding
a determination of the fair value of the shares of all dissenting holders. The
Surviving Corporation does not presently intend to file an appraisal petition
and holders seeking to exercise appraisal rights should not assume that the
Surviving Corporation will file such a petition or that the Surviving
Corporation will initiate any negotiations with respect to the fair value of
such shares. Accordingly, Axion stockholders who desire to have their shares
appraised should initiate any petitions necessary for the perfection of their
appraisal rights within the time periods and in the manner prescribed in Section
262. Within 120 days after the Effective Time, any Axion stockholder who has
theretofore complied with the applicable provisions of Section 262 will be
entitled, upon written request, to receive from the Surviving Corporation, a
statement setting forth the aggregate number of shares of Axion Common Stock
with respect to which demands for appraisal were received by Axion and the
number of holders of such shares. Such statement must be mailed within 10 days
after the written request therefor has been received by the Surviving
Corporation or within 10 days after expiration of the time for delivery of
demands for appraisal under Section 262, whichever is later.

     If a petition for an appraisal is timely filed, at the hearing on such
petition, the Delaware Court will determine which holders are entitled to
appraisal rights and will appraise shares of Axion Common Stock owned by such
holders, determining the fair value of such shares exclusive of any element of
value arising from the accomplishment or expectations of the Merger, together
with a fair rate of interest, if any, to be paid upon the amount determined to
be the fair value. In determining fair value, the Delaware Court is to take into
account all relevant factors. In Weinberger v. UOP Inc., the Delaware Supreme
Court discussed the factors that could be considered in determining fair value
in an appraisal proceeding, stating that "proof of value by any techniques or
methods which are generally considered acceptable in the financial community,
and otherwise admissible in court" should be considered, and that "fair price
obviously requires consideration of all relevant factors involving the value of
a company." The Delaware Supreme Court stated that in making this determination
of fair value the court must consider market value, asset value, dividends,
earnings, prospects, the nature of the enterprise and any other facts which
could be ascertained as of the date of the merger which throw light on future
prospects of the merged corporation. In Weinberger, the Delaware Supreme Court
stated that "elements of future value, including the nature of the enterprise,
which are known or susceptible of proof as of the date of the merger and not the
product of speculation, may be considered." Section 262, however, provides that
fair value is to be "exclusive of any element of value arising from the
accomplishment or expectation of the merger."

     Axion stockholders considering seeking appraisal should recognize that the
fair value of their shares determined under Section 262 could be more than, the
same as or less than the consideration they are to receive pursuant to the
Merger Agreement if they do not seek appraisal of their shares. The cost of the
appraisal proceeding may be determined by the Delaware Court and taxed against
the parties as the Delaware Court deems equitable in the circumstances. Upon
application of a dissenting Axion stockholder, the Delaware Court may order that
all or a portion of the expenses incurred by any dissenting holder in connection
with the appraisal proceeding, including without limitation, reasonable
attorney's fees and the fees and expenses of experts, be charged pro rata
against the value of all shares entitled to appraisal.

     Any holder of shares of Axion Common Stock who has duly demanded appraisal
in compliance with Section 262 will not, after the Effective Time, be entitled
to vote for any purpose any shares subject to such demand or to receive payment
of dividends or other distributions on such shares, except for dividends or
distributions payable to stockholders of record at a date prior to the Effective
Time.

     At any time within 60 days after the Effective Time, any Axion stockholder
will have the right to withdraw such demand for appraisal and to accept the
terms offered in the Merger. After this period, such stockholder may withdraw
such demand for appraisal only with the consent of the Surviving Corporation. If
no petition for appraisal is filed with the Delaware Court within 120 days after
the Effective Time, holders' rights to appraisal shall cease, and all holders of
shares of Axion Common Stock will be entitled to receive the consideration
offered pursuant to the Merger Agreement. Inasmuch as the Surviving Corporation
has no obligation to file such a petition, and has no present intention to do
so, any holder of shares of Axion Common Stock who desires such a petition to be
filed is advised to file it on a timely basis.
   
     It is a condition to the obligation of BMS to effect the Merger that no
Dissenting Shares be outstanding at the Effective Time. See "Risk Factors--Vote
Required; Stockholder Agreement".

                                THE DISTRIBUTION
   
     This section of the Proxy Statement/Prospectus describes certain aspects of
the proposed Distribution. To the extent that they relate to the Distribution
Agreement, the following descriptions do not purport to be complete and are
qualified in their entirety by reference to such Agreement, which is attached as
Appendix B to this Proxy Statement/Prospectus, respectively, and is incorporated
herein by reference. All stockholders are urged to read such agreement in its
entirety.
    

Reasons for the Distribution

   
     The Retained Business constitutes the only business, assets and liabilities
of Axion that BMS has agreed to acquire. As a result, the disposition of the
Retained Business will be effected through a series of sequential transactions,
including the Contributions, the Distribution and the Merger, all as set forth
in the Merger Agreement and the Distribution Agreement. Prior to the Effective
Time, the Acquired Business will be transferred to AHC and OPUS Sub, and the AHC
Preferred Stock will be distributed to the stockholders of Axion in the
Distribution. After the Distribution and at the Effective Time, Axion will hold
the Retained Business, so that BMS will effectively acquire the Retained
Business in the Merger. The purpose of this complex structure is to permit the
disposition of the Retained Business in a transaction that should be tax free to
Axion's stockholders in which Axion stockholders will receive BMS Common Stock
and will also retain their proportionate equity interests in the Acquired
Business in the form of AHC Preferred Stock to be received in the Distribution.
In the event Axion stockholders do not approve the Merger, or if the Merger
Agreement is otherwise terminated, Axion nonetheless intends to consummate the
Contributions. See "Risk Factors--Certain Federal Income Tax Consequences" and
"Certain Federal Income Tax Consequences".

     Although the Distribution will not be effected unless the Merger is
approved and about to occur, the Distribution is separate from the Merger, and
the AHC Preferred Stock to be received by holders of Axion Common Stock and
holders of Axion Preferred Stock in the Distribution does not constitute a part
of the consideration to be received by Axion stockholders in the Merger. Axion
stockholders are not being asked to approve the Distribution, which is not
subject to stockholder approval. Axion stockholders should review the
Information Statement attached as Appendix G hereto for additional information
with respect to the Distribution, AHC and the AHC Preferred Stock. Consummation
of the Distribution is a condition to the Merger.
    

Terms of the Distribution Agreement
   
     Formation of OPUS Sub

     Prior to the execution of the Distribution Agreement, Axion will cause the
incorporation of OPUS Sub under Delaware law, and thereafter will not permit
OPUS Sub to engage in any business except as contemplated by the Distribution
Agreement.

     Distribution of the Preference Amount

     Immediately prior to the time as of which the Contributions are effective
(the "Time of Contribution") Axion will cause OTNC to cause OTN to distribute to
OTNC an amount equal to $13,615,147 (the "Preference Amount"), in full
satisfaction of all amounts that may be due as of, or in respect of any period
ending on or prior to, the Closing Date to OTNC in respect of its Capital
Account Prime Rate Amount and the General Partner Cumulative Preference Amount
(as each such term is defined in the Partnership Agreement). Notwithstanding the
preceding sentence, if the Closing Date occurs after September 30, 1996 and
Axion shall
    


                                       86

<PAGE>




   
not have used Best Closing Efforts (as defined below) to cause the Closing to
occur on or prior to September 30, 1996, the Preference Amount will be paid only
to the extent of cash and cash equivalents held by OTN as of September 30, 1996
(it being understood that for purposes of this paragraph the amount of cash and
cash equivalents held by OTN as of September 30, 1996 will be reduced by the
amount, if any, by which outstanding indebtedness for borrowed money, or any
guaranties in respect of any indebtedness for borrowed money of any third party,
in respect of which OTN is obligated on September 30, 1996 will exceed
$35,617,000). "Best Closing Efforts" means, in addition to Axion not otherwise
knowingly taking any action to frustrate or delay the Merger, the following: (i)
Axion will have diligently responded to all Commission comments to the Form S-4
related to Axion or its subsidiaries (A) within five business days after receipt
by Axion or its counsel of any initial Commission comments to the Form S-4 and
(B) within a reasonably prompt period under the circumstances after receipt by
Axion or its counsel of any subsequent Commission comments to the Form S-4; (ii)
in the event that the no-action relief requested by Axion from the Commission
with respect to the distribution of AHC Preferred Stock without registration
under the Securities Act is obtained from the Commission, the Information
Statement will have been distributed to Axion stockholders at the same time as
this Proxy Statement/Prospectus is distributed to such Axion stockholders; and

AHC Subsidiaries will: (i) (A) in the case of AHC, liquidate, dissolve or wind
up its affairs or (B) in the case of any 81% AHC

Subsidiary, liquidate, dissolve or wind up its affairs unless the assets of such
81% AHC Subsidiary (or, if such 81% AHC Subsidiary will not be wholly owned, a
proportionate amount of such assets equal to the direct and indirect ownership
interest of AHC in such 81% AHC Subsidiary) will have been distributed to or
otherwise acquired by AHC and/or any other 81% AHC Subsidiary; (ii) (A) merge
with or into or consolidate with any other person, or (B) sell, lease or
otherwise transfer all or substantially all the assets of AHC and the 81% AHC
Subsidiaries, taken as a whole (including by means of the sale of the capital
stock of any subsidiary) to any other person (in each case, whether in one or a
series of transactions), unless, in each case, such person explicitly agrees to
assume the obligations of AHC and the 81% AHC Subsidiaries under the
Indemnification Agreement, the Tax Matters Agreement or the Escrow Agreement
pursuant to an agreement reasonably satisfactory in form and substance to BMS
and its counsel; (iii) engage in any recapitalization or restructuring pursuant
to which any cash, securities or other property will be distributed in respect
of its capital stock or effect any other distribution (by means of dividend,
redemption or otherwise) in respect of its capital stock (other than, in the
case of any 81% AHC Subsidiary, any such distribution to AHC); (iv) enter into
any transactions with affiliates of AHC or any 81% AHC Subsidiary unless (1) any
such transaction is between or among AHC and the 81% AHC Subsidiaries or (2) the
terms of such transactions are fair and reasonable to AHC or the 81% AHC
Subsidiaries, as the case may be, as in a comparable transaction made on an
arm's length basis between unaffiliated parties; or (v) agree to or otherwise
suffer any of the foregoing in (i), (ii), (iii) or (iv) above or otherwise take
any action or fail to take any action designed to restrict, reduce or otherwise
limit the rights of the BMS Indemnified Parties under the Indemnification
Agreement, the Tax Matters Agreement or the Escrow Agreement or the ability of
any BMS Indemnified Party to collect any amount owed to it under the
Indemnification Agreement, Tax Matters Agreement or the Escrow Agreement. For
purposes of this covenant, OnCare and its subsidiaries are deemed to be
affiliates of AHC and the 81% AHC Subsidiaries.

     AHC will cause each of its subsidiaries that will be or become an 81% AHC
Subsidiary on or after the Closing Date to enter into an agreement, reasonably
satisfactory in form and substance to both BMS and its counsel and AHC and its
counsel, pursuant to which such subsidiary shall agree to be bound by the terms
of each of the Indemnification Agreement, the Tax Matters Agreement and the
Escrow Agreement as if such subsidiary were named an 81% AHC Subsidiary therein.

     The foregoing provisions of this "--Covenants" section will terminate on
the later of (a) the sixth anniversary of the Effective Time and (b) the
expiration of the statute of limitations (including any extensions thereof
arising from audits commenced on or before such sixth anniversary) for all
Federal income tax returns of the Affiliated Group (as defined in the Tax
Matters Agreement) for all taxable years ending on or before the day on which
the Effective Time occurs is in process, provided that the foregoing provisions
shall not terminate until such time as any Tax Claims (as defined in the Tax
Matters Agreement) relating to such audit or contest have been settled and all
liabilities related thereto satisfied.

     Appointment of AHC as Representative

     Execution and delivery of the Letter of Transmittal by each Former Axion
Stockholder will result in each such Former Axion Stockholder irrevocably
appointing AHC as his/her or its agent and attorney-in-fact to execute and
deliver on such Former Axion Stockholder's behalf, and thereby result in each
such Former Axion Stockholder becoming a party to and bound by, the
Indemnification Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution and delivery of the Letter of Transmittal will result in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder that may be necessary in connection with the transactions
contemplated by such agreements, including to give and receive notices on each
such Former Axion Stockholder's behalf and to represent each such Former Axion
Stockholder with respect to any matter, suit,

claim, action or proceeding arising with respect to any transaction contemplated
by such agreements, including the defense, appeal or settlement of any claim,
action or proceeding for which each such Former Axion Stockholder may be
obligated to indemnify any person pursuant to such agreements or may be entitled
to indemnification pursuant to such agreements or which may be brought by BMS
against each such Former Axion Stockholder to enforce such indemnity; and will
result in each such Former Axion Stockholder ratifying and confirming any action
taken by AHC in the exercise of the power of attorney granted thereby.

     See "Risk Factors--Indemnification Obligations of the Former Axion
Stockholders, AHC and the 81% AHC Subsidiaries" and "The Merger-Indemnification
Arrangements; Escrow; Appointment of AHC as Representative".
    

Terms of the Tax Matters Agreement

   
     Prior to the Time of Distribution, BMS, BMS Sub, Axion, certain
subsidiaries of Axion, AHC, the 81% AHC Subsidiaries, the Partnership and the
Former Axion Stockholders will enter into a Tax Matters Agreement which sets
forth each party's rights and obligations with respect to payments of Federal,
state, local or foreign Taxes for periods before and after the Merger and
related matters such as the filing of and right to tax returns and the control
of tax contests.

     The Tax Matters Agreement specifically provides that: the AHC Indemnifying
Parties will jointly and severally indemnify and hold harmless BMS, the
Surviving Corporation, OPUS, OTNC, the Partnership, their affiliates and each of
their respective officers, directors, employees, stockholders, agents and
representatives (collectively, the "BMS Indemnified Parties") from all
liabilities for Federal, state, local, foreign and other governmental taxes,
assessments, duties, fees, levies or similar charges of any kind including all
interest, penalties and additions imposed with respect to such amounts
(collectively, "Taxes") imposed on Axion, OPUS, OTNC or any member of the
Affiliated Group (as defined in the Tax Matters Agreement) (whether imposed
directly or by reason of United States Treasury Regulations Section 1.1502-76 or
similar provisions) (i) for any pre-merger tax period, including any Pre-JV
Sales Taxes (but excluding any Retained Tax Liabilities), which are in each case
unpaid as of the Effective Time (the "Pre-Merger Taxes"), (ii) with respect to
the Contributions, (iii) as a result of the Distribution, (iv) as a result of
the provision of the OPUS Station Data (as defined in the Distribution
Agreement) to AHC, OnCare or any of their assignees, (v) with respect to the
OPUS License Agreement or (vi) in respect of the transfer of assets or rights
from OnCare or any of its subsidiaries or affiliates or any other affiliate of
Axion and its subsidiaries to Axion prior to the Distribution. The AHC
Indemnifying Parties shall also jointly and severally indemnify the BMS
Indemnified Parties from all liabilities for fifty percent (50%) of any
liability for any unpaid Taxes (other than JV Sales Taxes) as of June 30, 1996
imposed on the Partnership for all periods up to and including June 30, 1996 in
excess of $225,000, and 100% of any liability for JV Sales Taxes paid after June
30, 1996 in excess of $667,402; provided, however, that no indemnification shall
be payable with respect to any JV Sales Taxes to the extent payment of such JV
Sales Taxes increased the amount of "Retained Cash" pursuant to clause (c) of
the definition of "Retained Cash" in the Distribution Agreement. "Retained Tax
Liabilities" shall mean (W) any income Tax liability (including any liability
for any Tax measured by reference to income) of OTNC (or the Affiliated Group)
attributable to the allocation to OTNC of Taxable income of the Partnership
(whether or not such taxes are paid before or after the Effective Time) and any
other Taxes to the extent directly attributable to the operation of the
Partnership, in each case for the period beginning on July 1, 1996, and ending
on the day on which the Effective Time occurs and in each case determined in
accordance with certain principles provided therein and (for the avoidance of
doubt) in the case of Taxes measured by reference to income, by assuming that
such income is subject to Tax at the highest applicable federal, state and local
tax rate as otherwise provided therein, (X) any income Tax liability (including
any liability for any Tax measured by reference to income) to the extent
directly attributable
    


                                       96

to the reallocation of Partnership income by the IRS or any other governmental
agency from BMOTN to OTNC, (Y) all liabilities for any unpaid Taxes as of June
30, 1996 imposed on the Partnership for all periods up to and including June 30,
1996 that are not indemnified by the AHC Indemnifying Parties pursuant to the
preceding sentence, and (Z) any Tax liabilities relating to the operations,
assets or activities of a BMS Entity (other than the Partnership). "Pre-JV Sales
Taxes" shall mean any liability of Axion with respect to unpaid sales and use
Taxes on sales prior to the date of formation of the Partnership. "JV Sales
Taxes" shall mean any liability of the Partnership with respect to unpaid sales
and use Taxes on sales prior to August 1, 1994.

     The BMS Indemnifying Parties will jointly and severally indemnify and hold
harmless the AHC Indemnified Parties (A) from all liability for Taxes imposed on
the Surviving Corporation, OTNC, OPUS or the Partnership for any Post-Merger Tax
Period and (B) for any Retained Tax Liabilities.

     Other provisions of the Tax Matters Agreement provide AHC with the ability,
under certain circumstances, to control tax contests relating to a claim for
which AHC would indemnify the BMS Indemnified Parties and, under certain
circumstances, allow AHC to obtain refunds for taxes paid by Axion prior to the
Effective Time, up to a certain threshold.

     The indemnification obligations of the AHC Indemnifying Parties under the
Tax Matters Agreement survive for the term of the applicable statute of
limitations (generally six years). Other than in the case of fraud by a Former
Axion Stockholder, the indemnification obligations of the Former Axion
Stockholders are limited to the Escrowed Shares; the indemnification obligations
of AHC are unlimited.

     Appointment of AHC as Representative

     Execution and delivery of the Letter of Transmittal by each Former Axion
Stockholder will result in each such Former Axion Stockholder irrevocably
appointing AHC as his/her or its agent and attorney-in-fact to execute and
deliver on such Former Axion Stockholder's behalf, and thereby result in each
such Former Axion Stockholder becoming a party to and bound by, the
Indemnification Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution and delivery of the Letter of Transmittal will result in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder that may be necessary in connection with the transactions
contemplated by such agreements, including to give and receive notices on each
such Former Axion Stockholder's behalf and to represent each such Former Axion
Stockholder with respect to any matter, suit, claim, action or proceeding
arising with respect to any transaction contemplated by such agreements,
including the defense, appeal or settlement of any claim, action or proceeding
for which each such Former Axion Stockholder may be obligated to indemnify any
person pursuant to such agreements or may be entitled to indemnification
pursuant to such agreements or which may be brought by BMS against each such
Former Axion Stockholder to enforce such indemnity; and will result in each such
Former Axion Stockholder ratifying and confirming any action taken by AHC in the
exercise of the power of attorney granted thereby.

     See "Risk Factors--Indemnification Obligations of the Former Axion
Stockholders, AHC and the 81% AHC Subsidiaries" and "The Merger--Indemnification
Arrangements; Escrow; Appointment of AHC as Representative."

Terms of the Escrow Agreement

     Deposit of Escrowed Property

   
     Pursuant to the Escrow Agreement, at the Closing (a) the Exchange Agent, on
behalf of the Former Axion Stockholders, will deposit into escrow, and the
Escrow Agent will acknowledge receipt of, a number of shares of BMS Common Stock
equal to $5,000,000 divided by the Average Value of BMS Common Stock, rounded to
the nearest whole share, which amount will be deemed to have been deposited by
the Former Axion Stockholders on a pro rata basis from the shares of BMS Common
Stock to be issued and delivered to each Former Axion Stockholder with respect
to its shares of Axion Common Stock pursuant to the Merger Agreement as
described under "The Merger--Terms of the Merger Agreement--Conversion of Axion
Common Stock in the Merger" herein, calculated based on the ratio of the number
of shares of BMS Common Stock to be so issued and delivered to such Former Axion
Stockholder with respect to its shares of Axion Common Stock to the aggregate
number of shares of BMS Common Stock to be so issued to all the Former Axion
Stockholders with respect to their shares of Axion Common Stock. Such shares
together with any dividends and distributions with respect to such shares as set
forth in the Escrow Agreement and any income received from the investment
thereof, as on deposit or invested from time to time in accordance with the
terms of the Escrow Agreement are referred to as the "Escrowed Shares", and (b)
AHC will deposit, or cause to be deposited into escrow, and the Escrow Agent
will acknowledge receipt of, $5,000,000 in cash. Such cash, together with any
income received thereon, as on deposit or invested from time to time in
accordance with the terms of the Escrow Agreement, is referred to as the
"Escrowed Cash" (the Escrowed Shares and the Escrowed Cash together being the
"Escrowed Property"). During the term of the Escrow Agreement, BMS will, from
time to time and concurrently with the payment thereof, (a) deliver to the
Escrow Agent for deposit in accordance with the terms of the Indemnification
Agreement, all non-taxable stock dividends and other non-taxable distributions
made with respect to the Escrowed Shares and (b) deliver to the Escrow Agent,
who will promptly distribute the same to the Former Axion Stockholders, all cash
distributions and other taxable distributions (other than taxable distributions
representing the proceeds of a sale or acquisition or a substantial
restructuring in connection with a sale or acquisition of only BMS) made with
respect to the Escrowed Shares. BMS and each AHC Indemnifying Party acknowledge
and agree that, to the extent and so long as any of the Escrowed Property is
held by the Escrow Agent hereunder, BMS will have, as of and from the date such
Escrowed Property is received by the Escrow Agent, a perfected first priority
security interest in such Escrowed Property to secure the payment of the amount,
if any, payable by an AHC Indemnifying Party pursuant to the Indemnification
Agreement and the Tax Matters Agreement. Each of BMS and each of the AHC
Indemnifying Parties agree that the Escrowed Shares will be voted by the Escrow
Agent with respect to all matters as to which the holders of BMS Common Stock
are entitled to vote in accordance with written instructions from AHC as the
representative of the Former Axion Stockholders. AHC agrees that if any Former
Axion Stockholder provides AHC with written directions as to how to vote the
Escrowed Shares with respect to any matter, AHC will instruct the Escrow Agent
to vote such number of Escrowed Shares as are beneficially held for such Former
Axion Stockholder as so directed by such Former Axion Stockholder, and if no
such directions are received with respect to particular Escrowed Shares on any
matter for which such Escrowed Shares may be voted, AHC will direct the Escrow
Agent to abstain from voting such Escrowed Shares with respect to such matter.
    

     Disposition of Escrowed Property

   
     At any time on or prior to the Escrowed Cash Termination Date (as defined
below), BMS may deliver a certificate to the Escrow Agent requesting delivery of
Escrowed Property to BMS, and the Escrow Agent will deliver the Escrowed
Property to BMS to the extent and at the time provided in accordance with the
Escrow Agreement; provided, however, that (i) no distribution of Escrowed
Property will be made in respect of any
    


                                       98

Indemnified Obligation (as defined below) related to a liability for Taxes for
which a BMS Indemnified Party is indemnified pursuant to the Tax Matters
Agreement unless and until such time as such liability for Taxes will be deemed
liquidated and therefore payable in accordance with the provisions of the Tax
Matters Agreement, (ii) after the Escrowed Shares Termination Date (as defined
herein), no Escrowed Shares will be released to BMS except with respect to an
Escrowed Shares Pending Claim (as defined herein) and (iii) after the Second
Anniversary Date (as defined herein), Second Anniversary Cash shall be released
to BMS only with respect to Second Anniversary Pending Claims (as defined
herein). For purposes of the foregoing, the amount of Second Anniversary Cash as
of any date will equal the excess, if any, of the amount of Escrowed Cash on
deposit with the Escrow Agent on such date over the amount specified in clause
(A) of the definition of "Retained Escrow Amount" (as defined herein) calculated
as of such date.

     Immediately following the Escrowed Shares Termination Date (as defined
below), if either (a) both BMS and AHC deliver a certificate to the Escrow Agent
or (b) the Escrow Agent (i) receives a certificate from AHC, (ii) delivers a
copy of such certificate to BMS and (iii) does not, within 15 business days
following delivery of such certificate to BMS, receive written notice from BMS
objecting to such certificate given by AHC, the Escrow Agent will deliver to AHC
as the representative of the Former Axion Stockholders such number of Escrowed
Shares (rounded to the nearest whole share) that equals, when multiplied by the
Average Value of BMS Common Stock, the excess, if any, of (x) the number of
Escrowed Shares on deposit with the Escrow Agent on the Escrowed Shares
Termination Date multiplied by the Average Value of BMS Common Stock over (y)
the amount of any unpaid Escrowed Shares Pending Claims (as defined below) on
the Escrowed Shares Termination Date. Thereafter, if as of the last day of any
fiscal quarter following the Escrowed Shares Termination Date, Escrowed Shares
remain on deposit with the Escrow Agent, and either (a) both BMS and AHC deliver
a certificate to the Escrow Agent or (b) the Escrow Agent (i) receives a
certificate from AHC, (ii) delivers a copy of such certificate to BMS and (iii)
does not, within 15 business days following delivery of such certificate to BMS,
receive written notice from BMS objecting to such certificate given by AHC, the
Escrow Agent will deliver to AHC as the representative of the Former Axion
Stockholders the number of Escrowed Shares that equals, when multiplied by the
Average Value of BMS Common Stock, the excess, if any, of (x) the number of
Escrowed Shares on deposit with the Escrow Agent on the last day of such fiscal
quarter multiplied by the Average Value of BMS Common Stock over (y) the amount
of any unpaid Escrowed Shares Pending Claims on the last day of such fiscal
quarter. "Escrowed Shares Pending Claims" means all Pending Claims (as defined
below) existing on the Escrowed Shares Termination Date. The amount of any
Escrowed Shares Pending Claim on any date will be determined in accordance with
the provisions of the Escrow Agreement. "Escrowed Shares Termination Date" means
the earlier to occur of (i) one year after the date of the Escrow Agreement and
(ii) complete distribution of the Escrowed Shares in satisfaction of claims for
Indemnified Obligations.

     Immediately following the second anniversary of the date of the Escrow
Agreement (the "Second Anniversary Date"), if either (a) both BMS and AHC
jointly deliver a certificate to the Escrow Agent or (b) the Escrow Agent (i)
receives a certificate from AHC, (ii) delivers a copy of such certificate to BMS
and (iii) does not, within 15 business days following delivery of such
certificate to BMS, receive written notice from BMS objecting to the certificate
given by AHC, the Escrow Agent will deliver to AHC an amount in cash equal to
the excess, if any, of Escrowed Cash on deposit with the Escrow Agent as of the
Second Anniversary Date over the Retained Escrow Amount on the Second
Anniversary Date. Thereafter, if as of the last day of any fiscal quarter
following the Second Anniversary Date, Escrowed Cash remains on deposit with the
Escrow Agent and either (a) both BMS and AHC deliver a certificate to the Escrow
Agent or (b) the Escrow Agent (i) receives a certificate from AHC, (ii) delivers
a copy of such certificate to BMS and (iii) does not, within 15 business days
following delivery of such certificate to BMS, receive written notice from BMS
objecting to such certificate given by AHC, the Escrow Agent will deliver to AHC
an amount in cash equal to the excess, if any, of
    


                                       99




<PAGE>
 

<PAGE>



   
Escrowed Cash on deposit with the Escrow Agent as of the last day of such fiscal
quarter over the Retained Escrow Amount as of the last day of such fiscal
quarter. "Retained Escrow Amount" means, as of any date, the sum of (A) an
amount, if any, equal to the excess of $1,000,000 over (i) the aggregate amount,
if any, of Escrowed Cash that will have been released during the period from the
Second Anniversary Date to such date in respect of any Pending Claim that was
not an existing Pending Claim at any time on or prior to the Second Anniversary
Date and (ii) the aggregate amount, if any, released to AHC pursuant to the
paragraph below from and after the Escrowed Cash Termination Date and (B) the
amount of any unpaid Second Anniversary Pending Claims on such date. "Second
Anniversary Pending Claims" means all the Pending Claims existing on the Second
Anniversary Date (and, for the avoidance of doubt, includes all Escrowed Shares
Pending Claims existing on such date). The amount of any Second Anniversary
Pending Claim on any date will be determined as provided in the Escrow
Agreement, provided that, for all purposes of this paragraph, the amount of
unpaid Second Anniversary Pending Claims on the last day of any fiscal quarter
ending after the Second Anniversary Date will be reduced by an amount equal to
(x) the number of Escrowed Shares on deposit with the Escrow Agent on the last
day of such fiscal quarter (such number to be determined based on the assumption
that any Escrowed Shares that are to be delivered to AHC as the representative
of the Former AHC Stockholders in respect of the last day of such fiscal quarter
as provided in the second sentence of the paragraph above will have been so
delivered and will not be on deposit with the Escrow Agent on the last day of
such fiscal quarter), if any, multiplied by (y) the Average Value of BMS Common
Stock.
    
     Immediately following the Escrowed Cash Termination Date, if either (a)
both BMS and AHC deliver a certificate to the Escrow Agent or (b) the Escrow
Agent (i) receives a certificate from AHC, (ii) delivers a copy of such
certificate to BMS and (iii) does not, within 15 business days following
delivery of such certificate to BMS, receive written notice from BMS objecting
to such certificate given by AHC, the Escrow Agent will deliver to AHC an amount
equal to the excess, if any, of Escrowed Cash on deposit with the Escrow Agent
as of the Escrowed Cash Termination Date (calculated as provided below) over an
amount equal to any unpaid Final Pending Claims (as defined below) on the
Escrowed Cash Termination Date. Thereafter, if as of the last day of any fiscal
quarter following the Escrowed Cash Termination Date Escrowed Cash remains on
deposit with the Escrow Agent and either (a) both BMS and AHC deliver a
certificate to the Escrow Agent or (b) the Escrow Agent (i) receives a
certificate from AHC, (ii) delivers a copy of such certificate to BMS and (iii)
does not, within 15 business days following delivery of such certificate to BMS,
receive written notice from BMS objecting to such certificate given by AHC, the
Escrow Agent will deliver to AHC an amount equal to the excess, if any, of
Escrowed Cash on deposit with the Escrow Agent as of the last day of such fiscal
quarter (calculated as provided below) over an amount equal to any unpaid Final
Pending Claims on the last day of such fiscal quarter. For purposes of this
paragraph, the amount of any Escrowed Cash on deposit with the Escrow Agent will
be calculated by treating the amount, if any, of Escrowed Cash that is to be
delivered to AHC pursuant to the paragraph above on such date as having been so
delivered and as not being on deposit with the Escrow Agent on such date. "Final
Pending Claims" means all Pending Claims existing on the Escrowed Cash
Termination Date (and, for the avoidance of doubt, includes all Escrowed Shares
Pending Claims and Second Anniversary Pending Claims existing on such date). The
amount of any Final Pending Claim on any date will be determined as provided in
the Escrow Agreement, provided that, for purposes of this paragraph the amount
of unpaid Final Pending Claims on the last day of any fiscal quarter ending
after the Escrowed Cash Termination Date will be reduced by an amount equal to
(x) the number of Escrowed Shares on deposit with the Escrow Agent on the last
day of such fiscal quarter (such number to be determined based on the assumption
that any Escrowed Shares that are to be delivered to AHC as the representative
of the Former AHC Stockholders in respect of the last day of such fiscal quarter
is provided in the second sentence of the second paragraph of "--Disposition of
Escrowed Property" above will have been so delivered and will not be on deposit
with the Escrow Agent on the last day of such fiscal quarter), if any,
multiplied by (y) the Average Value of BMS Common Stock. The "Escrowed Cash
Termination Date" means the earlier to occur of (i) six years after the


                                      100




<PAGE>
 

<PAGE>



date of the Escrow Agreement and (ii) complete distribution of the escrowed cash
in satisfaction of claims for Indemnified Obligations.

     Either BMS or AHC may deliver to the Escrow Agent a certificate accompanied
by a final and nonappealable award or order of a court of competent jurisdiction
(a "Court Order") with respect to the payment of all or any portion of the
Escrowed Property requesting delivery of Escrowed Property to BMS, AHC or such
other person(s) as may be specified in such award or order. Such certificate
also will be accompanied by an opinion of outside counsel to the effect that the
applicable court award or order is final and nonappealable. In either such case,
the Escrow Agent will deliver all or a portion of the Escrowed Property to BMS
or AHC, as the case may be, in the amount specified in the Court Order.

   
     If AHC has delivered to the Escrow Agent and BMS at any time within 30 days
before or after the due date (including extensions) for payment by AHC of its
final Federal income tax liability for a taxable year (or, if later, 30 days
after the Escrow Agent supplies all information relating to the income realized
with respect to the Escrowed Cash necessary to prepare the certificate referred
to in this paragraph a certificate setting forth the amount of Federal and State
of California income tax due from AHC with respect to any taxable income
realized with respect to the Escrowed Cash for such taxable year (based on the
assumption that AHC is, with respect to such income, subject to Federal and
State of California income tax at the highest regular marginal tax rate
applicable to corporations for such year), and the accuracy and completeness of
such certificate is certified by Ernst & Young or such other nationally
recognized accounting firm chosen by AHC and reasonably satisfactory to BMS,
then the Escrow Agent will pay to AHC in cash the amount set forth in such
certificate no more than 15 days after receipt of such certificate. The Escrow
Agent will use commercially reasonable efforts to supply to AHC the tax
information referred to above prior to the start of the 60-day period referred
to above.
    

     All distributions under the Escrow Agreement that are not the subject of a
dispute will be made no later than 20 days from receipt of a certificate and
will be made from the Escrowed Shares and/or the Escrowed Cash, as the case may
be, in accordance with the provisions described above. Distributions made to BMS
pursuant to the provisions described above will first be made from any Escrowed
Shares on deposit and then, to the extent so required, from any Escrowed Cash.
Distributions made pursuant to the preceding paragraph will be deemed to have
been made from the Escrowed Cash.

   
     If BMS delivers a written notice to the Escrow Agent objecting to any
Certificate from AHC requesting the release of the Escrowed Property, such
notice must specify the disputed amount of such release request and the amount
not in dispute. The Escrow Agent will deliver to AHC the amount of such release
request not in dispute.

     Each Escrowed Share distributed pursuant to the Escrow Agreement is valued
at a price per share equal to the Average Value of BMS Common Stock, rounded to
the nearest whole share. All Escrowed Shares distributed to AHC will be
distributed by AHC pro rata to the Former Axion Stockholders based on the ratio
of the number of shares of BMS Common Stock received by such Former Axion
Stockholder at the Closing to the aggregate number of shares of BMS Common Stock
received by all Former Axion Stockholders at the Closing.
    

     Distributions for Indemnified Obligations

     At any time on or prior to the Escrowed Cash Termination Date, BMS may
deliver to the Escrow Agent a certificate (i) stating that (A) a BMS Indemnified
Party has incurred an Indemnifiable Loss against which such BMS Indemnified
Party is entitled to be indemnified pursuant to the Indemnification Agreement or
(B) a BMS Indemnified Party is liable for Taxes against which such BMS
Indemnified Party is entitled to be indemnified


                                      101

pursuant to the Tax Matters Agreement (each, an "Indemnified Obligation"), (ii)
stating the aggregate amount of such Indemnified Obligation (or, in the case of
an unliquidated Indemnified Obligation, a good faith and reasonable estimate
thereof) and (iii) specifying in reasonable detail the nature of each item
included in such Indemnified Obligation (an "Indemnification Item"), the amount
thereof and the date on which such Indemnification Item was paid or incurred;
provided, however, that BMS may not deliver to the Escrow Agent a certificate
stating that a BMS Indemnified Party is liable for Taxes against which such BMS
Indemnified Party is entitled to be indemnified pursuant to the Tax Matters
Agreement unless and until any of the following will have occurred: (a) a Tax
Return will have been filed as provided in the Tax Matters Agreement showing
such Taxes to be due and payable and the full amount of such Taxes will not have
been paid at the time such Tax Return was filed; (b) a Taxing Authority will
have asserted in writing or determined that there is a deficiency with respect
to such Taxes; (c) except with respect to any claim for indemnification for
Taxes relating in any respect to (i) the Contributions, the Distribution, the
Merger or any of the other Transactions, (ii) any sales or use Taxes, other than
(A) Pre-JV Sales Taxes, (B) JV Sales Taxes and (C) any liability of any BMS
Indemnified Party with respect to unpaid sales and use taxes on rentals of OPUS
Station machines, and (iii) the distribution of the stock of OnCare by Axion,
BMS will have received an opinion of a nationally recognized accounting firm or
law firm reasonably acceptable to AHC that it is more likely than not that such
Taxes will be properly payable; or (d) there will have been a "determination"
(as defined in Section 1313 of the Code) that such Taxes are due and payable.

     If AHC objects to the Indemnified Obligation specified in such certificate,
AHC will, within 10 business days after delivery of the written notice
containing a copy of any such Certificate, deliver to the Escrow Agent a
certificate (a "Reply Certificate"), (i) specifying each such amount to which
AHC objects and (ii) specifying in reasonable detail the nature and basis for
each such objection. Within five business days of delivery to the Escrow Agent
of a Reply Certificate, the Escrow Agent will deliver a copy of such Reply
Certificate to BMS. BMS and AHC will negotiate in good faith for a period of 30
days after delivery of such Reply Certificate to BMS to reach a written
resolution of any matters raised in a Reply Certificate.

     If no Reply Certificate is delivered with respect to any certificate or any
Indemnification Item contained therein, then AHC will be deemed to have
acknowledged BMS's right to receive any amount or amounts specified in such
certificate (or the undisputed portion thereof), and the Escrow Agent will
transfer to BMS, Escrowed Property in an amount equal to the undisputed amount
claimed in such certificate (plus interest at a rate per annum equal to the
prime rate announced from time to time by The Chase Manhattan Bank on such
amount from the later of (i) the date of such certificate and (ii) the date such
indemnified amount was actually incurred by the applicable Indemnified Party),
all in accordance with the procedures set forth in the Escrow Agreement.

     If the Escrow Agent receives a Reply Certificate in a timely manner, the
disputed amount requested for reimbursement pursuant to the applicable
certificate will be held by the Escrow Agent and will not be released to BMS
except in accordance with either (i) written instructions signed by each of an
authorized officer of BMS and AHC or (ii) the final nonappealable judgment of a
court having jurisdiction over the matters relating to the claim by the
applicable Indemnified Party for indemnification from AHC accompanied by an
opinion of outside counsel to the effect that the applicable judgment is final
and nonappealable, at which date the portion of the amount due to such
Indemnified Party determined pursuant to clauses (i) or (ii) in this paragraph
will promptly be paid to BMS in accordance with the procedures set forth in the
Escrow Agreement.

   
     The payment of Indemnified Obligations contemplated by the Escrow Agreement
will not be deemed to be a waiver of any right, claim or amount to which BMS may
be entitled under the Indemnification Agreement, the Tax Matters Agreement or
otherwise, including any claim relating to an Indemnified Obligation, to the
extent
    


                                      102

that the amount paid to BMS pursuant hereto is insufficient to satisfy the
entire amount of any such Indemnified Obligation.
    

     Notwithstanding anything to the contrary set forth in "--Disposition of
Escrowed Property" and "--Distributions for Indemnified Obligations", upon
receipt of written notice from the Escrow Agent containing a copy of a
certificate relating to an Indemnified Obligation the final amount of which will
have been liquidated, AHC may elect to pay to BMS such amount in cash in lieu of
payment being made from the Escrowed Property if AHC, within ten business days
after delivery of the written notice containing a copy of the certificate, will
have delivered to BMS and the Escrow Agent a written notice stating its election
to make such cash payment and, thereafter, will have made such cash payment to
BMS on the earliest date that a payment of Escrowed Property would otherwise be
made hereunder with respect to such Indemnified Obligation; provided, however,
that such Indemnified Obligation will constitute a Pending Claim for all
purposes of this Agreement until the time the full amount of such cash payment
is actually received by BMS.

     Pending Claims

     "Pending Claims" means, at any time, (a) all indemnification claims with
respect to which a certificate will have been delivered at or prior to such time
with respect to which the final amount of such claims will have been liquidated
and which will not have been paid in full at such time whether because the
payment of such amount is in dispute or otherwise and (b) all indemnification
claims with respect to which a Certificate will have been delivered and with
respect to which the final amount of such claim will not have been liquidated.

     The amount of any Pending Claim as of any date will be equal to BMS's
reasonable estimate of such amount. If any Pending Claim exists on the last day
of any fiscal quarter during the term of the Escrow Agreement, not later than 10
business days after the last day of such fiscal quarter, BMS will deliver to the
Escrow Agent a certificate (a "Quarterly Certificate") setting forth BMS's
reasonable estimate of the amount of each then existing Pending Claim as of the
last day of such fiscal quarter, provided that, if BMS will not deliver a
Quarterly Certificate in respect of any fiscal quarter or will not include in
such Quarterly Certificate all Pending Claims existing on the last day of such
fiscal quarter, the amount of each Pending Claim (or the amount of any Pending
Claim not included in such Quarterly Certificate, as applicable) will be the
amount of each such Pending Claim set forth in the most recent Certificate
(including any Quarterly Certificate) delivered by BMS to the Escrow Agent in
respect of the amount of such Pending Claim, provided further that failure of
BMS to deliver a Quarterly Certificate in respect of any fiscal quarter will not
affect in any manner the obligations of the AHC Indemnifying Parties under the
Escrow Agreement, the Indemnification Agreement or the Tax Matters Agreement or
the rights of BMS or any other BMS Indemnified Party thereunder.

     If AHC reasonably objects to the amount of any Pending Claim specified in
any certificate delivered pursuant to the Escrow Agreement, AHC will, within 10
business days after delivery of such certificate, deliver to the Escrow Agent a
certificate (the "Amount Certificate"), (i) specifying each such amount to which
AHC reasonably objects and (ii) specifying in reasonable detail the nature and
basis for each such objection. Within five business days of delivery to the
Escrow Agent of the Amount Certificate, the Escrow Agent will deliver a copy of
such Amount Certificate to BMS. BMS and AHC will negotiate in good faith for a
period of 30 days after delivery by the Escrow Agent to BMS of such Amount
Certificate to reach a written resolution of any matters raised in the Amount
Certificate and, if such matters are not resolved within a 30-day period, either
party may bring an action to resolve such dispute as provided in the Escrow
Agreement. Notwithstanding the foregoing, the amount of any Pending Claim with
respect to which an Amount Certificate will have been delivered will be for all
purposes of the Escrow Agreement the amount reasonably determined by BMS as
provided in the paragraph above unless and until such time as the Escrow Agent
either (a) receives written


                                      103




<PAGE>
 

<PAGE>



instructions signed by an authorized officer of each of BMS and AHC adjusting
the amount of such Pending Claim or (b) the final nonappealable judgment of a
court having jurisdiction over the matters relating to the claim by the
applicable BMS Indemnified Party for indemnification from any AHC Indemnifying
Party adjusting the amount of such Pending Claim accompanied by an opinion of
outside counsel to the effect that the applicable judgment is final and
nonappealable, at which date, in the event that the Escrow Agent will have
received an Amount Certificate from AHC within the time frame set forth above,
the amount of the Pending Claim for all purposes of this Agreement will be
adjusted to the amount determined pursuant to clauses (a) or (b) of this
sentence.

   
     Escrow Agent

     The Escrow Agent shall not be liable except for its gross negligence or
wilful misconduct, and shall be indemnified jointly and severally by the AHC
Indemnifying Parties and the BMS Indemnifying Parties against losses or claims
arising out of or in connection with the Escrow Agreement. The Escrow Agent will
be required to make all Escrowed Property available for withdrawal on not less
than two business days' prior written notice.

     Appointment of AHC as Representative

     Execution and delivery of the Letter of Transmittal by each Former Axion
Stockholder will result in each such Former Axion Stockholder irrevocably
appointing AHC as his/her or its agent and attorney-in-fact to execute and
deliver on such Former Axion Stockholder's behalf, and thereby result in each
such Former Axion Stockholder becoming a party to and bound by, the
Indemnification Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution and delivery of the Letter of Transmittal will result in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder that may be necessary in connection with the transactions
contemplated by such agreements, including to give and receive notices on each
such Former Axion Stockholder's behalf and to represent each such Former Axion
Stockholder with respect to any matter, suit, claim, action or proceeding
arising with respect to any transaction contemplated by such agreements,
including the defense, appeal or settlement of any claim, action or proceeding
for which each such Former Axion Stockholder may be obligated to indemnify any
person pursuant to such agreements or may be entitled to indemnification
pursuant to such agreements or which may be brought by BMS against each such
Former Axion Stockholder to enforce such indemnity; and will result in each such
Former Axion Stockholder ratifying and confirming any action taken by AHC in the
exercise of the power of attorney granted thereby.

     See "Risk Factors--Indemnification Obligations of the Former Axion
Stockholders, AHC and the 81% AHC Subsidiaries" and "The Merger-Indemnification
Arrangements; Escrow; Appointment of AHC as Representative".
    

                            EFFECT OF TRANSACTIONS ON
                     AXION EMPLOYEES AND AXION BENEFIT PLANS

Transfer of Employment

     Each person listed on a schedule to the Distribution Agreement (the
"Transferred Employee Schedule") will be transferred to AHC effective upon the
Time of Distribution (the "Transferred Employees"). It is intended that all
employees of Axion, OPUS, OTN and OTNC who are not listed on the Transferred
Employee Schedule


                                      104




<PAGE>
 

<PAGE>



other than those employees listed on a schedule of Axion continuing employees
(the "Continuing Employee Schedule") will be deemed Transferred Employees
whether or not listed on the Transferred Employee Schedule. Prior to the Time of
Distribution, AHC will offer employment to each Transferred Employee on such
terms and conditions (including salary and benefit level) that are substantially
equivalent to the terms and conditions of the employee's employment with Axion,
OPUS, OTN or OTNC, as the case may be, immediately prior to the Time of
Distribution. Any Transferred Employee not actively-at-work as of the date
immediately following the Time of Distribution will nonetheless be deemed to be
an employee of AHC as of such date for all purposes and will be covered under
the benefit plans and arrangements of AHC to the fullest extent permitted by
such plans and arrangements. To the extent any Transferred Employee is not able
to be covered under any benefit plans or arrangements of AHC to the same extent
that such Transferred Employee would have been covered had he or she not been
included as a Transferred Employee, AHC will bear full responsibility to provide
the level of benefits that such Transferred Employee would have otherwise
received. AHC will recognize each Transferred Employee's prior service with
Axion, AHC, OPUS, OTN and OTNC and all members of Axion's controlled group
within the meaning of Section 414(b), (c), (m), and (o) of the Code for all
purposes under each employee benefit plan, policy or arrangement of AHC. AHC
will be solely liable for all liabilities, costs and expenses arising from any
Transferred Employee's failure or inability, for any reason, to accept AHC's
offer of employment and commence or continue such employment with AHC following
the Time of Distribution, including any and all severance or termination
benefits, benefit continuation obligations, or employment-related claims.

   
     BMS prior to the Effective Time will offer continuing employment to the
persons listed on the Continuing Employee Schedule (each a "Continuing
Employee").
    

OTNC Employment Agreements

   
     OTNC has entered into an employment agreement with David Levison (the
"Employment Agreement") which will become effective on the Closing Date.
Levison's employment under the Employment Agreement commences on the Closing
Date and continues for a period of two years. During that period, Levison will
serve as President of OTNC.

     The Employment Agreement provides that Levison will receive a base salary
of $220,000 for the period commencing on the Closing Date and ending on the
first anniversary of the Closing Date and an annual base salary of $240,000 for
the period commencing on the day following such anniversary and ending on the
second anniversary of the Closing Date. Levison will be eligible for a bonus for
1996 of $112,000, which is payable on February 1, 1997. For 1997 and the portion
of 1998 that falls within the term of the Employment Agreement, Levison's bonus
will be determined in accordance with the terms and conditions set forth in the
Bristol-Myers Squibb Company Performance Incentive Plan, provided, however, that
Levison's target bonus will not be less than 27% of his base salary. Levison's
actual bonus will be based upon the extent to which actual pretax earnings for a
given plan year exceed or fall short of budgeted pretax earnings. One half of
Levison's bonus will relate to the pretax results of OTNC and the other half
will relate to the pretax results of the Bristol-Myers Squibb
Oncology/Immunology division. In addition, Levison is entitled to receive a
special retention bonus of $50,000 on the first day after the first anniversary
of the Closing Date and a special retention bonus of $100,000 on the first day
after the second anniversary of the Closing Date, provided in each case that he
is employed by OTNC on such anniversary. Levison will also be entitled to
participate in all retirement and welfare benefit plans of BMS on the same basis
as other key employees of BMS. Levison will receive an option to purchase 5,500
shares of BMS Common Stock under the BMS 1983 Stock Option Plan and a car
allowance of $7,000 per year.
    


                                      105

     If OTNC terminates the employment of Levison without cause, or he
terminates his employment because OTNC (i) materially changes his duties and
responsibilities, (ii) reduces his base salary or target bonus or (iii) requires
him to transfer to a new work location which is more than 20 miles more distance
from Levison's primary residence than was his work location immediately prior to
the transfer, OTNC will be obligated to pay severance to Levison by continuing
to pay his base salary for the greater of 12 months or the remaining balance of
the Employment Agreement. Levison will also be entitled to continued medical,
dental and life insurance benefits through the term of the Employment Agreement.
Payment of these severance amounts is conditioned upon Levison not engaging in
any deliberate act or omission which would be detrimental or damaging to the
good will of OTNC or BMS or materially damaging to OTNC's or BMS's relationships
with its customers, suppliers or employees.

     If Levison's employment is terminated by OTNC for cause, all compensation
ceases as of the termination date. If Levison dies or becomes disabled during
the term of the Employment Agreement, all compensation payable under the
Employment Agreement ceases upon death or termination of employment due to
disability.

     Throughout the term of the Employment Agreement and for a period of one
year after termination of his employment, Levison is restricted in his ability
to engage in a business which competes with the businesses of OTNC and OPUS
Station. During his employment and after termination thereof, Levison is
prohibited from disclosing confidential information concerning the business of
OTNC. During the term of the Employment Agreement and for a two-year period
thereafter, Levison is restricted from soliciting any employee of OTNC to leave
OTNC in order to accept employment with any other company. In addition, each of
the Noncompetition Agreements provides that none of AHC or OnCare or any of
their respective subsidiaries or Michael D. Goldberg, the President and Chief
Executive Officer and a director of Axion, OnCare and AHC, or Garrett J. Roper,
the Senior Vice President and Chief Financial Officer of Axion, OnCare and AHC
and the Secretary and a director of AHC, will solicit Levison for employment or
hire, whether as an employee, consultant or otherwise, during the term of his
employment agreement with OTNC. See "Relationship with BMS--Noncompetition
Agreements".

     OTNC has entered into employment agreements substantially similar to David
Levison's (other than compensation amounts) with Warren Dodge, Bret Brodowy,
Michael Cunningham, Lynn Hammerschmidt and James Adams. Warren Dodge will serve
as Senior Vice President and General Manager of OTNC, Bret Brodowy as Vice
President of Automated Technologies, Michael Cunningham as Vice President of
Purchasing and Development, Lynn Hammerschmidt as Vice President of Marketing
and James Adams as Vice President of Customer Service. These additional
employment agreements contain similar severance, non-compete, confidentiality
and non-solicitation provisions to those contained in David Levison's Employment
Agreement. These employees will receive shares of BMS Common Stock through the
Merger. See "The Merger--Interests of Certain Persons in the Transactions".
    

Axion Indemnification Agreements

   
     Axion has entered into certain indemnification agreements with its
directors and officers. See "The Merger--Interests of Certain Persons in the
Transactions". The Axion Certificate of Incorporation also provides for
exculpation of directors under certain circumstances. See "Comparison of Certain
Rights of Holders of BMS Common Stock, Holders of Axion Common Stock and Holders
of Axion Preferred Stock--Indemnification of Officers and Directors".

Transfer of Plans

     Savings Plan

   
     The Distribution Agreement provides that immediately prior to the Time of
Distribution, the Axion, Inc. 401K Profit Sharing Plan (the "Axion 401K Plan")
will be divided into two plans, each plan substantially identical to the Axion
401K Plan. One such plan will be maintained by Axion and will cover only those
participants who are Continuing Employees (the "New Axion 401K Plan"), and one
such plan will cover all other participants in the Axion 401K Plan, including
all participants who are Transferred Employees, retirees and vested terminated
participants in the Axion 401K Plan at the Time of Distribution (the "AHC 401K
Plan"). As of the Time of Distribution, the AHC 401K Plan will be transferred to
and assumed by AHC. As soon as practicable following the Time of Distribution,
Axion will cause an amount in cash (or property acceptable to AHC) to be
transferred from the trust under the Axion 401K Plan to the trust under the AHC
401K Plan equal to the sum of the account balances of (i) all Transferred
Employees, (ii) all retirees and (iii) all vested terminated participants in the
Axion 401K Plan with account balances under the Axion 401K Plan. Assets relating
to the accounts of Continuing Employees will be retained by the Axion 401K Plan
trust which shall be renamed the New Axion 401K Plan Trust. Axion and AHC will
cooperate in good faith to expedite the trust-to- trust transfer and to assure
the ongoing operation and administration of the New Axion 401K Plan and the AHC
401K Plan.
    

     Medical and Dental Benefits

     Effective as of the Time of Distribution, the Transferred Employees will
cease to be covered under the Aetna Medical and Dental Plan (the "Axion Health
Plan"). Axion will continue to maintain the Axion Health Plan for the Continuing
Employees (and their eligible dependents). Following the Distribution, AHC will
maintain a medical and dental plan and a corresponding flexible benefit plan to
cover the Transferred Employees (and their eligible dependents) on the same
basis and subject to the same conditions that would have applied absent the
Distribution. Subject to certain indemnification provisions, Axion will be
responsible for providing COBRA coverage to any former employee, retiree or
COBRA beneficiary entitled to such coverage under any Axion welfare benefit plan
as of the Time of Distribution.

     Other Welfare Benefits

     Following the Distribution, each Transferred Employee (and his or her
dependents) will continue to participate in a life and accidental death and
dismemberment plan on the same terms that would have applied absent the
Distribution. No Transferred Employee will be subject to any waiting period with
respect to such coverage under such plan which would not have applied absent his
or her transfer of employment to AHC. As of the Time of Distribution, and
subject to completion of the Merger, each Continuing Employee will receive
similar welfare benefits under the plans of BMS which apply to similarly
situated employees of BMS.

     Disability Coverage

     Following the Distribution, each Transferred Employee will continue to
participate in a long-term disability plan on the same terms that would have
applied absent the Distribution. No Transferred Employee will be subject to any
waiting period or pre-existing condition exclusion with respect to such
disability coverage which would not have applied absent his or her transfer of
employment to AHC. In accordance with the foregoing, AHC will be responsible for
providing long-term disability benefits to each Transferred Employee who is or
becomes disabled before, on or after the Time of Distribution and each former
employee of Axion who becomes


                                      107




<PAGE>
 

<PAGE>



disabled before the Time of Distribution regardless of whether such former
employee would have been a Transferred Employee if he or she had not become
disabled. As of the date immediately following the Time of Distribution, and
subject to completion of the Merger, each Continuing Employee will be eligible
to participate in the long-term disability coverage provided under the plans and
policies of BMS subject to the same coverage levels and other terms and
conditions (including waiting periods and pre-existing condition exclusions) as
a newly hired employee of BMS.

Retained Plans

     The plans maintained by Axion that will not be transferred to AHC (the
"Retained Plans") are the following: (a) the Axion 1989 Plan and the 1995 Plan,
each of which will terminate at the Effective Time, (b) the Axion Health Plan,
which will be retained by Axion and will provide health benefits for the
Continuing Axion Employees, and (c) the Axion Pharmaceuticals, Inc. (as amended
to be the OTNC) Flexible Employee Benefit Plan, which will continue to be
maintained by Axion for the benefit of the Continuing Axion Employees.

     With respect to all options granted under the Axion 1989 Plan and the Axion
1995 Plan and currently outstanding, the Merger will constitute a "Corporate
Transaction" for purposes of both the Axion 1989 Plan and Axion 1995 Plan, with
the following consequences:

   
     (a)  any option granted under the Axion 1989 Plan not yet exercisable will
          become exercisable in full upon consummation of the Merger and the
          holder thereof will be entitled to exercise such option immediately
          before the Time of Contribution with respect to any or all of the
          shares of Axion common stock then subject to the option;

     (b)  the shares issuable upon exercise of an option granted under either
          the Axion 1989 Plan or Axion 1995 Plan and shares already issued upon
          exercise of an option granted under the Axion 1989 Plan which in each
          case are unvested at the Time of Contribution will become fully
          vested, and Axion's repurchase rights with respect to such unvested
          shares will automatically lapse upon consummation of the Merger;

     (c)  Axion will extend an Employee Loan to each holder of an option
          outstanding under the Axion 1989 Plan or the Axion 1995 Plan equal to
          the exercise price for all of the shares purchasable under each such
          option, the proceeds of which such optionee may use to exercise his or
          her option. Each such Employee Loan shall be full recourse, may or may
          not be secured, shall bear interest at the applicable Federal rate
          established by the IRS and shall be due at the end of two years,
          subject to acceleration to the extent the optionee sells any of the
          Axion shares purchased with the note (other than in the Merger) or the
          BMS shares received in exchange for such Axion shares; and

     (d)  each option granted under the Axion 1989 Plan and each option granted
          under the Axion 1995 Plan will be canceled immediately prior to the
          Time of Contribution to the extent not exercised prior to the Time of
          Contribution.
    

     The Axion 1989 Plan and the Axion 1995 Plan will terminate at the Effective
Time.

Severance Arrangements

     Axion has adopted the Oncology Therapeutics Network Corporation Officers
Severance Plan ("Severance Plan") effective January 1, 1996 for the benefit of
David Levison and four other individuals who have entered

                                     108







<PAGE>
 

<PAGE>



   
into employment contracts with OTNC to continue in employment after the Merger.
The Severance Plan provides for the payment of certain severance benefits in the
event of the eligible employee's involuntary termination, other than a
termination for cause, within the twelve (12) month period following certain
changes in control. The Merger constitutes a change in control for purposes of
the Severance Plan and accordingly will trigger severance benefits for an
eligible employee if his employment is involuntarily terminated by BMS within
twelve months of the Merger. An eligible employee's termination of employment by
Axion will not trigger severance benefits under the Severance Plan if the
individual is employed in a comparable position by BMS or a subsidiary. The
Severance Plan provides for a lump sum cash payment equal to 12 months of the
eligible employee's base salary plus the employee's full target bonus for the
fiscal year in which the employment termination occurs. Pursuant to their
respective Employment Agreements, David Levison and the four other individuals
have waived their rights to receive benefits under the Severance Plan. These
Employment Agreements provide for certain severance payments. See "--OTNC
Employment Agreements".
    

                              RELATIONSHIP WITH BMS

     Following the Merger, AHC will continue to have certain relationships with
BMS and its subsidiaries.

Indemnification Agreement; Escrow Agreement; Tax Matters Agreement

   
     AHC, the 81% Subsidiaries (including OPUS Sub), the Former Axion
Stockholders, BMS, the Surviving Corporation, OPUS, OTNC and the Partnership
will be parties to the Indemnification Agreement, the Tax Matters Agreement and
the Escrow Agreement. See "Indemnification Arrangements--Terms of the
Indemnification Agreement"; "--Terms of the Tax Matters Agreement"; and "--Terms
of the Escrow Agreement".
    

Noncompetition Agreements

   
     BMS has entered into separate Noncompetition Agreements with AHC and OnCare
and each of Michael D. Goldberg, the President and Chief Executive Officer of
Axion, OnCare and AHC and a director of Axion, or Garrett J. Roper, the Senior
Vice President and Chief Financial Officer of Axion, OnCare and AHC and the
Secretary of AHC (the "Noncompetition Agreements") which will become effective
at Closing and will, for two years following the Closing Date, prohibit such
entities or persons and their affiliates, as the case may be, from, as
applicable, ownership, management, operation or control of, employment by,
holding certain equity interests in or serving as a director, advisor or
consultant to, or having certain other relationships with, any entity that
engages in the distribution of oncology drugs, supplies or biologics to certain
customers of OTN or the automated drug dispensing and inventory tracking systems
business in the United States. In addition, each of the Noncompetition
Agreements provides that none of AHC or OnCare or any of their respective
subsidiaries or Michael Goldberg or Garrett Roper will solicit for employment or
hire, whether as an employee, consultant or otherwise, David Levison, President
of OTNC, during the term of his employment agreement with OTNC.
    

AHC Supply Agreement; OnCare Supply Agreement; AHC Medstation Agreement; OnCare
Medstation Agreement.

   
     Pursuant to the AHC Supply Agreement and OnCare Supply Agreement, which
will become effective at the Closing, each of AHC and OnCare, respectively, will
purchase from OTN all the products and supplies offered by OTN required by all
oncology treatment facilities that are either owned by AHC or OnCare, as the
case may be, or any of their respective subsidiaries or controlled affiliates,
managed by AHC or OnCare, as the case may
    


                                      109




<PAGE>
 

<PAGE>



   
be, or any of their respective subsidiaries or controlled affiliates or which
AHC or OnCare, as the case may be, or any of their respective subsidiaries or
controlled affiliates has the authority at the discretion of the oncology
treatment facility to purchase products or supplies. In general OTN will provide
each of AHC and OnCare the lowest prices at which OTN sells such products or
supplies to other oncology physician management companies with the authority to
make purchasing decisions on behalf of physician office practices which have
agreed to make purchase or other commercial commitments equivalent to those
agreed to by AHC or OnCare, as the case may be, provided that in the event AHC
or OnCare, as the case may be, receives an offer pricing products or supplies at
a price of at least 10% less than the lowest price offered by OTN and OTN
chooses not to match such lower offer, AHC or OnCare, as the case may be, may
purchase such products or supplies pursuant to such lower offer for a term to
end upon the later of 30 days after the receipt of such lower offer and the term
of such lower offer. The existing supply agreement between OTN and OnCare will
terminate on the Closing Date.

     Similar arrangements have been made between each of AHC and OnCare and OPUS
pursuant to the AHC Medstation Agreement and the OnCare Medstation Agreement,
respectively, regarding the lease from OPUS of OPUS Stations. As of June 30,
1996, eight OPUS Stations were in use at six different oncology practices
operated by OnCare. The relevant OPUS Station agreements will remain in effect
after the Closing.
    

License Agreement

   
     In the License Agreement, AHC will agree to provide to the Surviving
Corporation a royalty-free exclusive, fully paid up right and license to use the
"OPUS" name and other scheduled intellectual property in connection with the
OPUS Station Business for a period of one year. The License Agreement also
provides that the Surviving Corporation may use certain supplies bearing the
"Axion" name as specified in the License Agreement for a period of not more than
two months; provided that the Surviving Corporation agrees to use commercially
reasonable efforts to terminate its use of such supplies as soon as practicable
following the Effective Time.
    

Transitional Services Agreement

   
     In the Transitional Services Agreement, AHC will agree to provide to Axion
certain services, including certain financial and information systems services,
at cost, and the Surviving Corporation will agree to provide to AHC certain
services, including certain information systems services, at $15,000 per month.
The services provided under the Transitional Services Agreement will be
performed for a period of three months after the date thereof with renewals of
one month upon the mutual consent of the parties with such renewals not to
exceed an aggregate of three months in addition to the original term.
    

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

   
     The following summary describes the material federal income tax
consequences of the Distribution and the Merger to holders of Axion capital
stock who are citizens or residents of the United States. This discussion does
not consider all the tax consequences that may be relevant to Axion stockholders
entitled to special treatment under the Code (such as insurance companies,
dealers in securities, tax exempt organizations or, except as specifically
provided below, foreign persons) or to Axion stockholders who acquired their
shares of Axion Common Stock pursuant to the exercise of employee stock options
or otherwise in compensatory transactions. In addition, this discussion does not
address any state, local or foreign tax considerations nor does it address any
federal estate, gift, employment, excise or other non-income tax consideration.
The following discussion is based upon provisions of the Code, regulations,
administrative rulings and judicial decisions presently in effect,
    


                                      110

all of which are subject to change (possibly with retroactive effect) or to
different interpretations. ALL AXION STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN
TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE DISTRIBUTION AND
THE MERGER, INCLUDING THE APPLICABILITY OF FEDERAL, STATE, LOCAL AND FOREIGN TAX
LAWS.
    

     The Distribution

   
     In the opinion of Ernst & Young, certified public accountants to Axion,
based upon certain representations of BMS, BMS Sub, Axion, AHC and certain
Former Axion Stockholders, the Distribution should qualify as a tax-free spinoff
under Section 355 of the Code. In such event, the following consequences would
obtain:
    

     1. An Axion stockholder should not recognize any income, gain or loss as a
result of the Distribution.

     2. An Axion stockholder should apportion the tax basis of his or her Axion
Common Stock between such Axion Common Stock and AHC Preferred Stock received in
the distribution in proportion to the relative fair market values of such Axion
Common Stock and AHC Preferred Stock immediately following the Distribution.

   
     3. An Axion stockholder's holding period for the AHC Preferred Stock
received in the Distribution should include the holding period applicable to the
Axion Common Stock with respect to which the Distribution was made, provided
that such Axion Common Stock is held as a capital asset by such stockholder as
of the date of the Distribution.

     4. Under current law, no gain or loss should be recognized by Axion as a
result of the Distribution, except to the extent that immediately after the
Distribution AHC Preferred Stock is owned (either directly, or indirectly
through one or more entities that are treated for United States tax purposes as
partnerships, estates or trusts) or deemed to be owned by certain individuals
who are not citizens or residents of the United States or by certain foreign
corporations (such actual or deemed owners are collectively referred to herein
as "Non-United States Holders"). AHC Preferred Stock that is owned by entities
that are treated for United States tax purposes as partnerships, estates or
trusts will for this purpose be deemed to be indirectly owned by Non-United
States Holders unless certain certification procedures are complied with by the
partners of such partnerships or the beneficiaries of such trusts or estates. In
the case of such direct or indirect ownership by certain Non-United States
Holders, Axion will recognize gain in an amount equal to the excess of the value
of the AHC Preferred Stock that is so held by such Non-United States Holders
over Axion's tax basis in such stock. It is expected that at the Time of
Distribution a substantial portion of Axion Common Stock will be held by
Non-United States Holders. Based on Axion's business judgment as to the value of
the businesses to be distributed by Axion in the Distribution, Axion does not
expect that it will incur a material amount of tax liability as a result of the
distribution of AHC Preferred Stock to Non-United States Holders. It should also
be noted that legislation (the "Proposed Legislation") has been proposed that
would cause the Distribution to constitute a taxable event to Axion whereby
Axion would recognize gain in an amount equal to the excess of the value of the
AHC Preferred Stock distributed over Axion's tax basis in such stock, whether or
not such stock is owned by Non-United States Holders. While the Proposed
Legislation has not yet been enacted into law, as currently drafted such
legislation would, if enacted, apply retroactively to the Distribution. Based on
Axion's business judgment as to the value of the businesses to be distributed by
Axion in the Distribution, Axion does not expect to report a material amount of
tax liability on its federal income tax returns as a result of the distribution
of AHC Preferred Stock even if the Proposed Legislation were adopted with an
effective date that applied to the Distribution. There can be no assurance,
however, that the IRS will agree with Axion's business judgment as to the
valuation of the businesses to be distributed by Axion in the Distribution or
will not establish a higher valuation that would make Axion's tax liability
higher, and, accordingly, there can be no assurance that the distribution of the
AHC Preferred Stock
    


                                      111




<PAGE>
 

<PAGE>



   
to Non-United States Holders or the adoption of the Proposed Legislation would
not cause Axion to incur a material amount of tax liability. Pursuant to the Tax
Matters Agreement, the AHC Indemnifying Parties have agreed to indemnify the BMS
Indemnified Parties against such tax liability, which may result in a claim
against part or all of the Escrowed Cash or the Escrowed Shares or directly
against the AHC Indemnifying Parties. Regardless of the existence of Non-United
States Holders or whether the Proposed Legislation is adopted, Axion and/or its
subsidiaries may also be required to recognize gain as a result of the transfer
of various assets and liabilities among various entities in anticipation of the
Distribution.
    

     No ruling from the IRS has been or will be sought with respect to any of
the tax matters relating to the Distribution. The opinion of Ernst & Young
described above will not be binding on the IRS. In addition, Axion stockholders
should be aware that such opinion is based on Ernst & Young's interpretation as
to how various requirements of Code Section 355 should apply to the particular
facts presented by the Distribution. With respect to some of these
interpretations, no direct legal precedents exist. Accordingly, there can be no
assurance that the IRS will agree with the conclusions set forth in the Ernst &
Young opinion. Moreover, no published rulings or cases squarely address the
qualifications of a transaction identical to the Distribution under Section 355
of the Code.

     A successful IRS challenge to the qualification of the Distribution as a
tax-free spinoff qualifying under Section 355 of the Code (as a result of the
inaccuracy of any of the representations of BMS, BMS Sub, Axion, AHC or certain
Former Axion Stockholders, or otherwise) would result in the following
consequences:

   
     1. Axion would recognize gain in an amount equal to the excess of the value
of the AHC Preferred Stock distributed to Axion stockholders over Axion's tax
basis in such stock (to the extent such gain has not previously been recognized
by Axion in connection with the distribution of AHC Preferred Stock to
Non-United States Holders). As noted above, Axion does not expect that it would
incur a material amount of tax liability. Also as noted above, Axion and/or its
subsidiaries may also be required to recognize gain as a result of the transfer
of various assets and liabilities among various entities in anticipation of the
Distribution, regardless of whether the Distribution qualifies as a tax-free
spinoff under Section 355 of the Code.

     2. The receipt of AHC Preferred Stock would constitute a taxable
distribution to all Axion stockholders (including Non-United States Holders) so
that the fair market value of the AHC Preferred Stock received by an Axion
stockholder would be treated (i) first, as a dividend to the extent of such
Axion stockholder's share of Axion's current and accumulated earnings and
profits, (ii) next, as a tax-free return of capital to the extent of such
stockholder's tax basis in the Axion Common Stock with respect to which the AHC
Preferred Stock is distributed (as determined, for Axion stockholders who hold
two or more blocks of stock with different bases, on a block-by-block approach
rather than by aggregating the bases of all blocks of stock held by each Axion
stockholder) and (iii) finally, as gain from the sale of Axion Common Stock. In
addition, Axion would incur certain withholding tax liabilities to the extent
such distributions were made to certain foreign individuals and entities.

     3. An Axion stockholder's aggregate basis in the shares of AHC Preferred
Stock received in the Distribution would equal the fair market value of such
shares, and the stockholder's holding period for such AHC Preferred Stock would
not include the period during which the shares of Axion Stock were held.

     Under the Tax Matters Agreement, the AHC Indemnifying Parties have agreed
to indemnify the BMS Indemnified Parties against any tax liability arising from
the failure of the Distribution to qualify as a tax-free
    


                                      112

spinoff under Section 355 of the Code or any other tax liabilities arising from
the Contributions, the Distribution or the related transactions. See
"Indemnification Arrangements--Terms of the Tax Matters Agreement".
    

     The Merger

   
     In the opinion of Gunderson Dettmer Stough Villeneuve Franklin & Hachigian,
LLP, counsel for Axion, and Ernst & Young LLP, accountants for Axion, based on
certain representations of BMS, BMS Sub, Axion, AHC and certain Former Axion
Stockholders, the Merger will qualify as a reorganization under Section 368(a)
of the Code. Provided that the Merger does so qualify, the following results
should obtain:
    

     1. No gain or loss will be recognized by stockholders of Axion who exchange
all of their shares of Axion Common Stock solely for shares of BMS Common Stock
in the Merger.

     2. No gain or loss will be recognized by Axion as a result of the Merger.

     3. The aggregate tax basis of the BMS Common Stock received in the Merger
(including any BMS Common Stock held in escrow) by each Axion stockholder will
be the same as the aggregate tax basis of the shares of Axion Common Stock
surrendered in exchange therefor.

     4. The holding period for each share of BMS Common Stock received in the
Merger will include the period during which the shares of Axion Common Stock
surrendered in exchange therefor were held, provided that such shares of Axion
Common Stock were held as capital assets at the Effective Time.

   
     5. A stockholder who exercises dissenter's rights with respect to a share
of Axion Common Stock and who receives payment for such stock in cash will
generally recognize capital gain or loss (if such share were held as a capital
asset at the Effective Time) measured by the difference between the Axion
stockholder's basis in such share and the amount of cash received, provided that
such payment is neither essentially equivalent to a dividend nor has the effect
of a distribution of a dividend (a "Dividend Equivalent Transaction"). (See
Sections 302 and 356(A)(2) of the Code.) A sale of Axion Common Stock pursuant
to an exercise of dissenter's rights will generally not be a Dividend Equivalent
Transaction if, as a result of such exercise, the Axion Stockholder exercising
dissenter's rights owns no shares of BMS Common Stock (either actually or
constructively within the meaning of Section 318 of the Code.) If, however, an
Axion stockholder's sale for cash of Axion Common Stock pursuant to an exercise
of dissenter's rights is a Dividend Equivalent Transaction, then such Axion
stockholder will generally recognize ordinary dividend income for federal income
tax purposes in an amount up to the entire amount of cash so received.
    

     It is a condition to the obligation of BMS to effect the Merger that no
Dissenting Shares be outstanding at the Effective Time.

     No ruling from the IRS has been or will be sought with respect to any of
the tax matters relating to the Merger. The opinions described above will not be
binding on the IRS and there can accordingly be no assurance that the IRS will
agree with the conclusions set forth therein.

     A successful IRS challenge to the status of the Merger as a reorganization
under Section 368(a) of the Code (as a result of the inaccuracy of any of the
representations of BMS, BMS Sub, Axion, AHC or certain Former Axion
Stockholders, or otherwise) would result in an Axion stockholder recognizing
gain or loss with respect to each share of Axion Common Stock surrendered equal
to the difference between the fair market value, as of the Effective Time, of
the BMS Common Stock received in exchange therefor and the stockholder's tax
basis in



                                      113

<PAGE>



   
such Axion stock. In such event, an Axion stockholder's aggregate basis in the
shares of BMS Common Stock received in the exchange would equal the fair market
value of such shares, and the stockholder's holding period for such BMS Common
Stock would not include the period during which the shares of Axion stock were
held. In addition, a successful IRS assertion that the Merger does not qualify
as such a reorganization would also cause the Distribution to fail to qualify as
a tax-free spinoff under Section 355 of the Code which, as noted above, could
result in significant tax liability to Former Axion Stockholders as well as
indemnification obligations of Former Axion Stockholders and the other AHC
Indemnifying Parties. See "Indemnification Arrangements--Terms of the Tax
Matters Agreement".

     For tax purposes, AHC will be deemed to own the Escrowed Cash and each of
the Former Axion Stockholders will be deemed to own its pro rata share of the
Escrowed Shares. Any taxable income earned or amounts realized in respect of the
cash or stock held in the Escrow Account shall be for the account of AHC or the
Former Axion Stockholders, respectively, and such parties have agreed to report
such amounts in such manner. If any Escrowed Shares are released to BMS pursuant
to the terms of the Indemnification Agreement or the Tax Matters Agreement, the
basis of such released Escrowed Shares will be allocable to the remaining shares
of BMS Common Stock received in the Merger held by the applicable Former Axion
Stockholder on a pro rata basis, or if no such shares are then held by such
Former Axion Stockholder, such release could result in the recognition of loss
by such Former Axion Stockholder.

     The foregoing summary is included herein for general information only. Such
opinions are based in part on representations provided by Axion and BMS. The
summary does not address the Federal income tax consequences to all categories
of Axion stockholders, including those who acquired shares of Axion capital
stock pursuant to the exercise of stock options or otherwise in compensatory
transactions. EACH AXION STOCKHOLDER IS URGED TO CONSULT HIS OR HER TAX ADVISOR
AS TO THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE DISTRIBUTION AND THE
MERGER, INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND FOREIGN INCOME
AND OTHER TAX LAWS.
    

                       DESCRIPTION OF CAPITAL STOCK OF BMS

General

     The following description of the material terms of the authorized capital
stock of BMS does not purport to be complete and is qualified in its entirety by
reference to the Restated Certificate of Incorporation of BMS (the "BMS
Certificate of Incorporation"), the By-laws of BMS (the "BMS By-laws") and the
Rights Agreement. See "Available Information."

   
     The authorized capital stock of BMS presently consists of 1,500,000,000
shares of BMS Common Stock and 10,000,000 shares of preferred stock, issuable in
series. As of July 31, 1996, 501,790,392 shares of BMS Common Stock and 15,698
shares of convertible preferred stock, par value $1.00 per share, of BMS (the
"BMS Convertible Preferred") were issued and outstanding. The BMS Board is
authorized to approve the issuance of one or more additional series of preferred
stock of BMS without further authorization of BMS's stockholders (except as may
be required under applicable stock exchange requirements), and to fix the number
of shares, the designations, the powers, preferences and relative,
participating, optional and other special rights of any such additional series
and the qualifications, limitations and restrictions thereof. Thus, any
additional series may, if so determined by the BMS Board, have full voting
rights with the BMS Common Stock or limited voting rights,
    


                                      114

be convertible into BMS Common Stock or another security of BMS, and have such
other powers, preferences and relative, participating, optional and other
special rights, and such qualifications, limitations and restrictions thereof,
as the BMS Board shall determine.

Common Stock

     The holders of BMS Common stock are entitled to receive dividends when and
as declared by the BMS Board out of funds legally available therefor, subject to
the terms of any preferred stock of BMS at the time outstanding.

     The holders of BMS Common Stock are entitled to one vote for each share on
all matters voted on by stockholders, including elections of directors. The
holders of BMS Common Stock do not have any cumulative voting, conversion,
redemption or preemptive rights. In the event of dissolution, liquidation or
winding up of BMS, holders of BMS Common Stock will be entitled to share
ratably, together with any participating preferred stock of BMS, in any assets
remaining after the satisfaction in full of the prior rights of creditors,
including holders of indebtedness of BMS, and the aggregate liquidation
preference of any preferred stock of BMS then outstanding.

     The outstanding shares of BMS Common Stock are listed on the NYSE and the
PSE. Chase Mellon Shareholder Services, 85 Challenger Road, Overpeck Centre,
Ridgefield Park, New Jersey 07660 is the transfer agent and registrar for the
BMS Common Stock.

BMS Convertible Preferred

     Dividend Rights

     Holders of BMS Convertible Preferred are entitled to receive, when and as
declared by the BMS Board out of funds legally available for payment, annual
dividends in an amount per share equal to $2.00. Dividends on BMS Convertible
Preferred are payable on the first day of March, June, September and December of
each year. Dividends on the BMS Convertible Preferred are cumulative and accrue
on a day-to-day basis.

     For so long as the BMS Convertible Preferred is outstanding, BMS may not
declare or pay any dividend on BMS Common Stock or redeem or purchase any other
preferred stock of BMS or purchase BMS Common Stock, unless full cumulative
dividends on the BMS Convertible Preferred have been paid, or declared and funds
set apart for payment thereof.

     Conversion Provisions

     At the election of the holder thereof, each share of BMS Convertible
Preferred is convertible into shares of BMS Common Stock, subject to adjustment
as set forth below. As of the date of this Proxy Statement/Prospectus, each
share of BMS Convertible Preferred is convertible into 4.24 shares of BMS Common
Stock. With respect to shares of BMS Convertible Preferred called for
redemption, conversion rights will expire at the close of business on the date
fixed for redemption, unless BMS defaults in the payment of the redemption
price.

     No fractional shares will be issued upon conversion, and, in lieu thereof,
an adjustment in cash will be made based upon the closing price of BMS Common
Stock on the NYSE on the day of conversion.


                                      115




<PAGE>
 

<PAGE>



     The conversion rate will be subject to adjustment in certain events to
preserve the relative rights of holders of BMS Convertible Preferred, including
certain subdivisions and combinations of BMS Common Stock, certain
reclassifications, and certain consolidations and mergers of BMS. Adjustments in
the conversion rate will be deferred until cumulative adjustments shall have
resulted in a change of the conversion rate by at least one one-hundredth of one
share of BMS Common Stock. No payment or allowance will be made upon conversion
in respect of any accrued and unpaid dividends.

     Liquidation Rights

     In the event of a liquidation, dissolution or winding up of BMS, whether
voluntary or involuntary, the holders of BMS Convertible Preferred then
outstanding are entitled to receive $50.00 per share plus all accrued and unpaid
dividends.

     Redemption

   
     BMS Convertible Preferred is redeemable at any time, at the option of BMS,
in whole or in part, at the price of $50.00 per share together with accrued and
unpaid dividends at the date of redemption. If BMS shall redeem less than all of
the outstanding shares of BMS Convertible Preferred, the BMS Board will
determine the shares to be redeemed by lot.
    

     Voting Rights

     Each share of BMS Convertible Preferred entitles the holder thereof to one
vote per share, and except as otherwise provided by the BMS Certificate of
Incorporation or as required by law, the BMS Convertible Preferred and the BMS
Common Stock vote as one class except that when holders of shares of preferred
stock of BMS voting as a class are entitled to elect two directors as provided
in the BMS Certificate of Incorporation, such holders are not entitled to
participate with the BMS Common Stock in the election of any other directors.

     Without the affirmative vote of the holders of at least two-thirds of the
outstanding shares of BMS Convertible Preferred, BMS may not amend, alter or
repeal any provision of the BMS Certificate of Incorporation or BMS By-laws so
as to materially affect any of the powers, preferences and rights of BMS
Convertible Preferred. The holders of BMS Convertible Preferred have no other
voting rights except as required by law.

BMS Rights

   
     Each share of BMS Common Stock carries with it an associated right (a "BMS
Right") pursuant to the Rights Agreement dated as of December 4, 1987, between
BMS and The Chase Manhattan Bank, as Rights Agent (as amended, the "Rights
Agreement") that entitles holders of BMS Common Stock under certain
circumstances to buy one one-thousandth of a share of a new series of
participating preferred stock of BMS at an exercise price of $200. The BMS
Rights separate from the associated shares of BMS Common Stock and become
exercisable only after a person or group acquires beneficial ownership of 20% or
more of BMS Common Stock or commences a tender or exchange offer upon
consummation of which such person or group would beneficially own 30% or more of
BMS Common Stock.
    

     If any person (i) becomes the beneficial owner of 25% or more of BMS Common
Stock, other than pursuant to certain tender or exchange offers described in the
Rights Agreement, (ii) who is a 20% or more stockholder engages in certain self-
dealing transactions described in the Rights Agreement or (iii) engages in a


                                      116

merger transaction with BMS in which BMS is the surviving corporation and shares
of BMS Common Stock are not changed or converted, then each BMS Right not owned
by such person or related parties will entitle its holder to purchase, at the
BMS Right's then-current exercise price, shares of BMS Common Stock (or, in
certain circumstances as determined by the BMS Board, cash, property or other
securities of BMS) having a value of twice the BMS Right's exercise price. In
addition, if BMS is involved in a merger or other business combination
transaction with another person in which shares of BMS Common Stock are changed
or converted, or sells 50% or more of its assets or earning power to another
person, each BMS Right will entitle its holder to purchase, at the BMS Right's
then-current exercise price, common shares of such other person having a value
of twice the BMS Right's exercise price.

     BMS is generally entitled to redeem the BMS Rights at a price of $.01 per
BMS Right at any time until the 15th day following public announcement that a
20% position has been acquired.

   
                   COMPARISON OF CERTAIN RIGHTS OF HOLDERS OF
           BMS COMMON STOCK, HOLDERS OF AXION COMMON STOCK AND HOLDERS
                            OF AXION PREFERRED STOCK

     The rights of holders of BMS Common Stock are governed by the BMS
Certificate of Incorporation and the BMS By-laws. The rights of holders of Axion
Common Stock and holders of Axion Preferred Stock are governed by the Axion
Certificate of Incorporation and the Axion By-laws. Both BMS and Axion are
governed by the DGCL. Upon consummation of the Merger, the stockholders of Axion
will become stockholders of BMS. The BMS Certificate of Incorporation and the
BMS By-laws will remain in effect after the Merger. Below is a summary of
certain differences among the rights of holders of BMS Common Stock, holders of
Axion Common Stock and holders of Axion Preferred Stock, resulting from
differences in the respective BMS and Axion certificates of incorporation and
by-laws.

     The following summary does not purport to be a complete statement of the
rights of BMS stockholders under the BMS Certificate of Incorporation and the
BMS By-laws compared with the rights of holders of Axion Common Stock and
holders of Axion Preferred Stock under the Axion Certificate of Incorporation
and the Axion By-laws. This summary is qualified in its entirety by reference to
the respective BMS and Axion certificates of incorporation and by-laws. For
information regarding the AHC Preferred Stock, see "Description of AHC Capital
Stock" and "Comparison of Certain Rights of Holders of AHC Preferred Stock,
Holders of Axion Common Stock and Holders of Axion Preferred Stock" in the
Information Statement attached as Exhibit G hereto.

Voting

     The BMS Certificate of Incorporation provides that holders of BMS Common
Stock are entitled to one vote for each share held.

     The Axion Certificate of Incorporation provides that holders of Axion
Common Stock are entitled to one vote for each share held.

     The Axion Certificate of Incorporation provides that holders of Axion
Preferred Stock are entitled to the number of votes equal to the number of
shares of Axion Common Stock into which such shares of Axion Preferred Stock
could be converted on the record date for the vote or the date of the
solicitation of any written consent of Axion stockholders (excluding fractional
shares) and shall have voting rights and powers equal to the
    


                                      117




<PAGE>
 

<PAGE>



   
voting rights and powers of the holders of Axion Common Stock. Holders of Axion
Preferred Stock vote together as a single class with the holders of Axion Common
Stock upon all matters submitted to a vote of Axion stockholders. The Axion
Certificate of Incorporation also provides for certain matters specified therein
to be submitted to a vote of holders of Axion Preferred Stock, voting in some
cases together as a single class and in other cases separately by series.


No Cumulative Voting

     Neither the BMS Certificate of Incorporation nor the Axion Certificate of
Incorporation provides for cumulative voting.
    

Certain Business Combinations


     The BMS Certificate of Incorporation requires the affirmative vote of the
holders of at least 75% of the outstanding shares of stock of BMS entitled to
vote generally in the election of directors, voting together as a single class,
to approve any merger or other Business Combination (as defined therein, which
term includes a merger, consolidation, sale of all or substantially all the
assets of BMS, the adoption of a plan of liquidation and similar extraordinary
corporate transactions) between, or otherwise involving BMS and (i) any
Interested Stockholder (as defined therein) or (ii) any other person which is,
or after such Business Combination would be, an Affiliate or Associate (as
defined therein) unless (i) the transaction has been approved by a majority of
the Continuing Directors (as defined therein) or (ii) certain minimum price,
form of consideration and procedural requirements are satisfied.

   
     The Axion Certificate of Incorporation requires, so long as no fewer than
an aggregate of 500,000 shares of Axion Series A Preferred Stock, par value
$.001 per share (the "Axion Series A"), Axion Series B Preferred Stock, par
value $.001 per share (the "Axion Series B"), Axion Series C Preferred Stock,
par value $.001 per share (the "Axion Series C"), Axion Series D Preferred
Stock, par value $.001 per share (the "Axion Series D"), Axion Series E
Preferred Stock, par value $.001 per share (the "Axion Series E"), or Axion
Series F Preferred Stock, par value $.001 per share (the "Axion Series F") are
outstanding, that any transaction that would result in a reorganization of
Axion, or the merger or consolidation of Axion with or into another corporation,
or the effectuation by Axion of a transaction or series of transactions in which
more than 50% of the voting power of Axion is disposed of, or the sale of all or
substantially all of the assets of Axion must be approved by the holders of at
least 50% of the then outstanding shares of Axion Preferred Stock (excluding
from such vote the shares of any series of Axion Preferred Stock of which there
are fewer than 100,000 shares outstanding), voting together as a single class.

Rights Plan

     Each share of BMS Common Stock comes with an associated BMS Right to buy
one one-thousandth of a share of a new series of participating preferred stock
of BMS at an exercise price of $200 under certain circumstances. See
"Description of Capital Stock of BMS--BMS Rights".

     The Axion Certificate of Incorporation does not provide holders of Axion
Common Stock with any liquidation preference in the event of any liquidation,
dissolution, or winding up of Axion.

     The Axion Certificate of Incorporation provides that in the event of any
liquidation, dissolution, or winding up of Axion, whether voluntary or
involuntary, the holders of each share of Axion Preferred Stock shall be
entitled to be paid out of the assets of Axion legally available for
distribution to its stockholders the following liquidation preferences: $.75 per
share of Axion Series A, $3.40 per share of Axion Series B, $4.79 per share of
Axion Series C, $5.60 per share of Axion Series D, $7.25 per share of Axion
Series E, and $10.00 per share of Axion Series F, plus, for each such share, an
amount equal to all declared but unpaid dividends thereon, if any, to the date
fixed for distribution to such series (such sum, subject to certain adjustments,
the "Axion Preference Amount").

     After holders of Axion Preferred Stock have received their full Axion
Preference Amount, any remaining assets or surplus funds of Axion will be shared
by and distributed ratably among the holders of Axion Common Stock and the
holders of Axion Preferred Stock; provided, however, that holders of Axion
Series A, Axion Series B, Axion Series C, and Axion Series E are entitled to
participate in such ratable distribution and sharing only until such time as
they receive certain aggregate per share maximum amounts set forth in the Axion
Certificate of Incorporation.

     For purposes of the foregoing two paragraphs relating to the liquidation
rights of Axion Preferred Stockholders, a merger or consolidation of Axion into
or with another corporation, a sale, transfer or other disposition of all or
substantially all of Axion's assets or the effectuation by Axion of a
transaction or series of related transactions in which more than 50% of the
voting power of Axion is disposed of, shall, unless the holders of at least
66-2/3% of the Axion Preferred Stock, voting together as a class, elect in
writing otherwise, be deemed to be a liquidation, dissolution or winding up of
Axion.

     In the event Axion proposes to take any action regarding the liquidation,
dissolution or winding up of Axion which will involve the distribution of assets
other than cash, the value of the assets to be distributed to the holders of
Axion Preferred Stock is to be determined by the vote or written consent of the
Axion Board (subject to certain guidelines specified in the Axion Certificate of
Incorporation with respect to the valuation of securities), and such
determination will be binding upon the holders of Axion Preferred Stock.

Dividends

     The BMS Certificate of Incorporation provides that holders of BMS Common
Stock are entitled to receive dividends when and if declared by the BMS Board,
subject to the rights of the holders of outstanding shares of any other class of
BMS stock having preference over the BMS Common Stock as to the payment of
dividends and of sinking fund or retirement fund or other retirement payments,
if any, to which such holders are respectively entitled in preference to the BMS
Common Stock.

     The Axion Certificate of Incorporation provides that the holders of the
outstanding Axion Series A, Axion Series B, Axion Series C, Axion Series D,
Axion Series E and Axion Series F are entitled to receive in any fiscal year,
when and as declared by the Axion Board, out of any assets at the time legally
available therefor, dividends in cash at the rate of $.075 per share, $.34 per
share, $.42 per share, $.56 per share, $.725 per share and $1.00 per share,
respectively (subject to adjustment), per annum before any dividend is declared
or paid on shares of Common Stock. Dividends may be payable quarterly or
otherwise as the Axion Board may from time to time determine, and the right to
such dividends is not cumulative. The holders of the outstanding Axion Preferred
Stock can waive any dividend preference that such holders may be entitled to
receive upon the
    


                                      119

affirmative vote or written consent of the holders of at least 66-2/3% of the
Axion Preferred Stock then outstanding, voting or consenting as a single class
on an as-if-converted basis. The holders of the outstanding Axion Preferred
Stock have unconditionally and irrevocably waived the right to any such dividend
preference that such holders are entitled to receive through December 31, 1996.

     The Axion Certificate of Incorporation provides that no distributions (as
defined in the Axion Certificate of Incorporation) may be paid on the Axion
Common Stock until the holders of the outstanding Axion Preferred Stock have
first received dividends at the dividend rates specified in the preceding
paragraph. If, in any fiscal year, any cash or other distributions are declared
by the Axion Board to be paid on the Axion Common Stock as a class, then an
additional dividend must be paid at the same time to the holders of the
outstanding Axion Preferred Stock at the rate per share equal to the product of
(x) such per share dividend or other distribution on the Axion Common Stock,
multiplied by (y) the number of shares of Axion Common Stock into which each
share of Axion Preferred Stock is then convertible.

Conversion Rights

     The BMS Common Stock is not convertible.

     The Axion Common Stock is not convertible.

     The Axion Certificate of Incorporation provides that each share of Axion
Preferred Stock is convertible at any time, without the payment of any
additional consideration by the holder and at the option of the holder, into
such number of fully paid and nonassessable shares of Axion Common Stock as is
determined according to a formula set forth in the Axion Certificate of
Incorporation, subject to adjustment. Each share of Axion Preferred Stock will
automatically be converted into shares of Axion Common Stock at the applicable
conversion price then in effect upon the affirmative vote or written consent of
the holders of at least 66-2/3% of the Axion Preferred Stock then outstanding,
voting or consenting as a single class on an as-if converted basis. Axion may
not, by amendment of the Axion Certificate of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of the Axion Certificate of
Incorporation relating to conversion and must take all action necessary or
appropriate in order to protect the conversion rights of the holders of Axion
Preferred Stock against impairment.

Size and Classification of the Board of Directors

     The BMS Certificate of Incorporation divides the BMS Board into three
classes, each having staggered three year terms. The number of directors on the
BMS Board may be determined by a majority vote of the entire BMS Board. The BMS
Board is currently comprised of ten directors.

     The Axion Board currently consists of six directors and is not classified.
The number of authorized directors may be modified from time to time by
amendment of the Axion By-laws. So long as no fewer than 100,000 shares of Axion
Series A remain outstanding, the holders of the Axion Series A outstanding are
entitled to elect two directors at each election of Axion directors. So long as
no fewer than 500,000 shares of Axion Series B remain outstanding, the holders
of a majority of the Axion Series B outstanding are entitled to elect one
director at each election of Axion directors. So long as no fewer than 100,000
shares of Axion Series C remain outstanding, the holders of a majority of the
Axion Series C outstanding are entitled to elect one director at each election
of Axion directors. The holders of a majority of the Axion Common Stock
outstanding are entitled to elect the remaining Axion directors.

Removal of Directors

   
     The BMS Certificate of Incorporation and the BMS By-laws generally provide
that, subject to the rights of the holders of BMS Preferred Stock, directors may
be removed from office with or without cause only by the affirmative vote of the
holders of at least 75% of the outstanding shares of stock entitled to vote
generally in the election of directors, voting together as a single class.
    


     The Axion By-laws provide that, at a special meeting of stockholders called
for such purpose, the Axion Board or any individual director may be removed from
office, with or without cause, and a new director or directors elected by a vote
of stockholders holding a majority of the outstanding shares entitled to vote at
an election of directors.

Vacancies on the Board of Directors

     The BMS Certificate of Incorporation and the BMS By-laws provide that,
subject to the rights of the holders of BMS Preferred Stock, newly created
directorships resulting from any increase in the number of directors and any
vacancies on the BMS Board resulting from death, resignation, retirement,
disqualification, removal or other cause will be filled only by the affirmative
vote of a majority of the remaining directors then in office, even though less
than a quorum. The BMS Certificate of Incorporation provides that any directors
so elected will serve for the remainder of the full term of the class in which
the new directorship was created or the vacancy occurred.

     The Axion By-laws provide that vacancies and newly created directorships
resulting from any increase in the authorized number of directors may be filled
by a majority of the directors then in office, although less than a quorum, or
by a sole remaining director, and each director so elected shall hold office for
the unexpired portion of the term of the director whose place shall be vacant
and until his successor shall have been duly elected and qualified. Vacancies
are deemed to exist in the case of the death, removal or resignation of any
director, or if the stockholders fail at any meeting of stockholders of which
directors are to be elected to elect the number of directors constituting the
entire Axion Board.

     Under the Axion Certificate of Incorporation, any vacancy occurring because
of the death, resignation, or removal of a director elected by the holders of
Axion Series A, the holders of Axion Series B or the holders of Axion Series C
will be filled by the vote or written consent of the holders of a majority of
the shares of that series or, in the absence of such action by such holders, by
action of the remaining directors then in office. Any vacancy occurring because
of the death, resignation or removal of a director elected by the holders of
outstanding Axion Common Stock will be filled by the vote or written consent of
the holders of a majority of the outstanding shares of Axion Common Stock or, in
the absence of such action by such holders, by action of the remaining directors
then in office.

Amendments to the Certificate of Incorporation

     Under the BMS Certificate of Incorporation, the affirmative vote of the
holders of at least 75% of the outstanding voting stock is required to alter,
amend or adopt the provisions contained therein relating to the classified
board, filling vacancies on the BMS Board, prohibiting any action required or
permitted to be taken by the stockholders of BMS by written consent, prohibiting
the call of special meetings by stockholders, approval of Business Combinations
and certain amendments to the BMS By-laws.

     The Axion Certificate of Incorporation requires, so long as no fewer than
an aggregate of 500,000 shares of Axion Series A, Axion Series B, Axion Series
C, Axion Series D, Axion Series E or Axion Series F are outstanding, that the
amendment, repeal or addition of any provision of or to the Axion Certificate of
Incorporation that would adversely alter or change the preferences, rights,
privileges or powers of, or the restrictions provided for the benefit of, the
Axion Preferred Stock must be approved by the holders of at least 50% of the
then outstanding shares of Axion Preferred Stock (excluding from such vote the
shares of any series of Axion Preferred Stock of which there are fewer than
100,000 shares outstanding), voting together as a single class. Notwithstanding
the previous sentence, the Axion Certificate of Incorporation provides that
Axion reserves the right to amend, alter, change or repeal any provision
contained in the Axion Certificate of Incorporation, in the manner now or
hereafter prescribed by statute, and all rights conferred upon stockholders
therein are granted subject to that reservation.

Amendments to By-laws
    

     Under the BMS Certificate of Incorporation and the BMS By-laws, the BMS
By-laws may be altered, amended or repealed by the affirmative vote of the
holders of at least a majority of the outstanding voting stock or by a vote of
the majority of the whole BMS Board, except for amendments which affect certain
provisions relating to the classification and composition of the BMS Board,
which require the affirmative vote of holders of at least 75% of the outstanding
voting stock.

   
     The Axion By-laws provide that such By-laws may be repealed, altered or
amended or new By-laws adopted by the Axion stockholders. Under the Axion
By-laws, the affirmative vote of the holders of at least 66- 2/3% of the voting
power of all the then outstanding shares of the capital stock of Axion entitled
to vote generally in the election of directors, voting together as a single
class, is required to adopt, amend or repeal any provisions of the Axion
By-laws. The Axion Certificate of Incorporation requires, so long as no fewer
than an aggregate of 500,000 shares of Axion Series A, Axion Series B, Axion
Series C, Axion Series D, Axion Series E or Axion Series F are outstanding, the
approval of the holders of at least 50% of the then outstanding shares of Axion
Preferred Stock (excluding from such vote the shares of any series of Axion
Preferred Stock of which there are fewer than 100,000 shares outstanding),
voting together as a single class, to amend, repeal or add any provision to the
Axion By-laws, if such action would adversely alter or change the preferences,
rights, privileges or powers of, or the restrictions provided for the benefit
of, the Axion Preferred Stock. Notwithstanding the foregoing, the Axion
Certificate of Incorporation provides that the Axion Board may from time to time
make, amend, supplement or repeal any Axion By-law adopted by the Axion Board;
provided, however, that the stockholders of Axion may change or repeal any
By-law adopted by the Axion Board; and provided, further, that no amendment or
supplement to the Axion By-laws adopted by the Axion Board will vary or conflict
with any amendment or supplement to the Axion Certificate of Incorporation
adopted by the stockholders of Axion.
    

Special Meetings of Stockholders; Action by Written Consent

     The BMS Certificate of Incorporation and the BMS By-laws require that,
subject to the rights of the holders of any preferred stock of BMS, any action
required or permitted to be taken by the stockholders of BMS be taken only at an
annual meeting or at a special meeting of stockholders called by a majority of
the entire BMS Board or by the Chairman of the BMS Board, and prohibit
stockholder action by written consent in lieu of a meeting. Stockholders of BMS
are not permitted to call a special meeting of stockholders or to require that
the BMS Board call such a special meeting.


                                      122




<PAGE>
 

<PAGE>



   
     The Axion By-laws provide that special meetings of Axion stockholders may
be called at any time, for any purposes, only by the President of Axion or the
Axion Board. The Axion By-laws provide that any action required by statute to be
taken at any annual or special meeting of the stockholders, or any action which
may be taken at any annual or special meeting of the stockholders, may be taken
without a meeting, without prior notice and without a vote, if written consent
setting forth the action so taken is signed by the holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize such action at a meeting at which all shares entitled to vote thereon
were present and voted.
    

Indemnification of Officers and Directors

   
     The BMS By-laws provide that each BMS officer and director is indemnified
to the fullest extent permitted by law, against: (i) expenses incurred or paid
by the director or officer in connection with any claim made against such
director or officer, or any actual or threatened action, suit or proceeding in
which such director or officer may be involved by reason of being or having been
a director or officer of BMS, or of serving or having served another corporation
or entity at the request of BMS, and (ii) the amount or amounts paid (subject to
certain limitations) by the director or officer in settlement of any such claim
or action. Subject to the provisions of the General Corporation Law of the State
of Delaware, no director of BMS will be personally liable to BMS or BMS
stockholders for monetary damages for breach of fiduciary duty as a director,
except to the extent that such liability arises (i) from a breach of the
director's duty of loyalty, (ii) as a result of acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the Delaware General Corporation Law or (iv) any
transaction from which the director derived an improper personal benefit.
    

     The rights of indemnification provided by the BMS By-laws are severable,
are not exclusive of other rights to which any director or officer now or
hereafter may be entitled, will continue as to a person who has ceased to be an
indemnified person and will inure to the benefit of the heirs, executors,
administrators and other legal representatives of such a person. The provisions
of the indemnification provision under the BMS By-laws is deemed to be a
contract between BMS and each director or officer who serves in such capacity at
any time while such provision is in effect.

   
     The Axion By-laws provide that Axion shall indemnify its directors to the
fullest extent permitted by the DGCL and give Axion the power to indemnify its
officers, employees and other agents as set forth in the DGCL. The Axion
Certificate of Incorporation provides that a director of Axion will not be
personally liable to Axion or its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to Axion or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation or law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived any improper personal benefit. Any
repeal or modification of the preceding sentence by the stockholders of Axion
will not adversely affect any rights or protection of a director of Axion
existing at the time of such repeal or modification.

                         Report of Independent Auditors

The Board of Directors and Stockholders
Axion Inc.

We have audited the accompanying consolidated balance sheets of Axion Inc. as of
December 31, 1995 and 1994, and the related consolidated statements of
operations, stockholders' equity, and cash flows for each of the three years in
the period ended December 31, 1995. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Axion Inc. at
December 31, 1995 and 1994, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1995, in conformity with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements
          (in thousands of dollars, except share and per share amounts)

1. Accounting Policies

Basis of Presentation

Axion Inc. (individually or collectively with its consolidated subsidiaries, as
the sense requires, "Axion") is a leading cancer-focused healthcare service firm
providing cost containment solutions for the delivery of cancer care. Axion,
either directly or through the Oncology Therapeutics Network Joint Venture, L.P.
(the "Partnership"), provides a clinically oriented, single source of supply for
office based oncologists' oncology drugs and related supplies needs.

The accompanying financial statements include the accounts of Axion and the
following companies:

     Oncology Therapeutics Network Corporation ("OTNC"), and the Partnership, a
     partnership with Bristol-Myers Squibb Company ("BMS"). OTNC is the general
     partner of the Partnership and Bristol-Myers Oncology Therapeutic Network,
     Inc., a subsidiary of BMS ("BMOTN"), is the limited partner.
   
     OnCare Inc. ("OnCare"), Axion HealthCare Inc. ("AHC"), and OPUS Health
     Systems Inc. ("OPUS"). On December 31, 1995, the 40,000,000 common shares
     of OnCare, an oncology physician practice management company, owned by
     Axion were distributed by Axion to its shareholders (Note 2). AHC provides
     cancer specific managed care services to cancer care payers and providers,
     and OPUS is engaged in information systems applications for office-based
     oncologists. Both are in the early stages of development with limited
     revenues.
    
All intercompany accounts and transactions have been eliminated. The financial
interest of BMS in the Partnership is recorded as a minority interest.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

Cash and Cash Equivalents and Short-Term Investments

Cash equivalents include money market funds and highly liquid debt instruments
with original maturities of three months or less. The carrying amount of Axion's
cash and cash equivalents approximates its fair value.

Short-term investments consist of marketable securities. Effective January 1,
1994, Axion adopted Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" ("FAS 115").
Under FAS 115, investments in marketable securities are reported at fair value.
There was no significant cumulative effect as of January 1, 1994 of adopting FAS
115.

Marketable securities are designated as available for sale and are carried at
approximate fair value

Inventories

Inventories, which consist primarily of pharmaceuticals and supplies for cancer
therapy, are carried at the lower of cost or fair value using the average
weighted cost method.

                   Notes to Consolidated Financial Statements
          (in thousands of dollars, except share and per share amounts)

Property and Equipment

Property and equipment is stated at cost. Depreciation of property and equipment
is provided for using the straight-line method over the estimated useful lives
of the respective assets (which range from three to seven years). Leasehold
improvements are amortized over the shorter of the estimated useful life or the
lease term, using the straight-line method.

Revenue Recognition and Accounts Receivable

Axion sells substantially all of its products to U.S. office-based oncologists.
Revenue from sales is recognized when products are shipped. Axion conducts
ongoing credit evaluations of its customers and does not require collateral.
Concentrations of credit risk with respect to accounts receivable are limited
due to the large number of entities comprising Axion's customer base. Management
believes that Axion's allowance for doubtful accounts at December 31, 1995 and
1994 is adequate to cover its credit risk. The provision for possible
uncollectible accounts charged to operations was $520, $131 and $37 in 1995,
1994 and 1993, respectively. The amount of write-offs charged to the allowance
for doubtful accounts was $74, $3 and $7 in 1995, 1994 and 1993, respectively.

Sales Agency Agreement with BMS

Under the terms of a Sales Agency Agreement between the Partnership and BMS, the
Partnership is the exclusive sales agent for BMS oncology products (and any
other oncology products that BMS has the right to sell) to officebased
oncologists. The Partnership does not take title to the BMS products that it
sells. No product revenue is recognized by the Partnership on the sale of BMS
products; however, commission income on such BMS product sales is recognized and
included in net revenues. The Partnership does record the related customer
receivables for up to 180 days and the related payables to BMS (see Note 4).

Stock-Based Compensation

Axion accounts for its stock option grants in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25"). Under APB 25, no compensation expense is recorded for stock options
granted unless the exercise prices are at less than fair values at the dates of
grant.

Per Share Data

Net income (loss) per share has been computed based on the weighted average
shares of common outstanding and dilutive common equivalent shares outstanding.
Common equivalent shares represent shares of preferred stock outstanding (using
the if converted method) and stock options and warrants outstanding (using the
treasury stock method). In 1993, all common equivalent shares were excluded from
the per share computation due to their anti-dilutive effect as a result of the
net loss for the year. In 1994 and 1995, common equivalent shares have been
included in the per share computation.

   
2. Interest in OnCare
    
On June 7, 1995, Axion formed OnCare, an oncology physician practice management
company, to acquire and manage oncology practices. Axion received 40,000,000
shares of common stock of OnCare for $40. In July 1995, Axion advanced $5,000 to
OnCare to fund its initial development activities.

On August 11, 1995, OnCare acquired substantially all of the assets of an
oncology practice for $3,832, the issuance of warrants to acquire 1,800,000
shares of common stock in OnCare, and the assumption of certain liabilities.

                   Notes to Consolidated Financial Statements
          (in thousands of dollars, except share and per share amounts)

also entered into a long-term management services agreement providing for its
rights to manage the oncology medical group over a 40-year period. The
transaction was accounted for using the purchase method of accounting.

On December 31, 1995, the $5,000 advance was cancelled in part for 700,000
shares of Series A redeemable preferred stock to be issued by OnCare ($3,500)
and in part as a contribution to the capital of OnCare ($1,500). All of OnCare's
40,000,000 common shares held by Axion were distributed to Axion's shareholders.
The holders of each of Axion's preferred and common shares (and the holders of
options and other rights to acquire common shares) received 3.96327 shares of
OnCare common stock for each common equivalent share held in Axion. Axion
retained its interest in the Series A redeemable preferred stock of OnCare.
OnCare is obligated to redeem the Series A preferred stock at a redemption price
of $5 per share at the earlier of December 31, 1996, the closing of a qualifying
underwritten public offering of the common stock in OnCare, the merger or
consolidation of OnCare with or into another corporation, or the sale of all or
substantially all of OnCare's assets.

Operating results of OnCare for the period ended December 31, 1995 are included
in the consolidated statement of operations. Revenues of OnCare for 1995 were
$2,645 and its net loss was $670 after income tax credit benefit of $450
allocated from Axion.

OnCare ceased to be a consolidated subsidiary on December 31, 1995 as a result
of the distribution by Axion of its holdings of the common stock of OnCare. The
condensed financial position of OnCare at December 31, 1995 and Axion's
investment are summarized as follows:

4. The Partnership

In 1993, Axion entered into a series of agreements with BMS, whereby the
Partnership was formed. The Partnership is owned by Axion's wholly owned
subsidiary, OTNC (the "general partner"), and BMS' wholly owned subsidiary,
BMOTN (the "limited partner"). All obligations of each partner to the other are
fully and unconditionally guaranteed by Axion and BMS, respectively. The
Partnership commenced operations on August 23, 1993.

In forming the Partnership, each partner contributed $1,000 in cash. Axion
contributed its ongoing Oncology Therapeutics Network business (its primary
operating business of providing services and distributing oncology drugs and
related supplies to office-based oncologists), excluding any debts or
obligations, and BMS contributed certain of its customer lists and entered into
a Sales Agency Agreement, under which BMS agreed to provide the promotional
support of the Bristol Laboratories Oncology sales force and the Partnership was
appointed the exclusive sales agent for BMS oncology products (and any other
oncology products that BMS has the right to sell) to officebased oncologists.

As the general partner, OTNC manages all of the day-to-day operations of the
Partnership. In addition, Axion provides all administrative, operational and
other services necessary to support the functioning of the Partnership, subject
to being reimbursed for its costs by the Partnership. Such reimbursement totaled
$2,817 in 1995, $2,491 in 1994, and $1,080 in 1993, and has been eliminated in
consolidation.

Under the terms of the Sales Agency Agreement, all pricing decisions and title
to BMS products sold by the Partnership remain with BMS, including risk of loss
for all such products. The terms of the Sales Agency Agreement require that the
Partnership remit payment of invoices to BMS within 60 days of the issuance of
any invoice to a customer for BMS products. BMS will retain the risk of
collectibility of accounts receivable relating to all BMS products sold under
the Sales Agency Agreement. If after 180 days the amount has not been paid, the
Partnership turns over to BMS for collection the uncollected invoice and BMS
refunds to the Partnership the amount of the uncollected invoice that was
previously paid by the Partnership plus interest on the amount at an annual rate
of 12 percent, or, if lower, the maximum rate allowed by law. As of December 31,
1995, BMS accounts receivable and the payable to BMS under the Sales Agency
Agreement were $59,461 and $47,755, respectively. As of December 31, 1994, BMS
accounts receivable and the payable to BMS under the Sales Agency Agreement were
$43,887 and $36,508, respectively. No product revenues are recorded by the
Partnership in connection with the sale of BMS

products. BMS pays the Partnership a commission based upon sales of BMS
products. Such commissions totalled $9,412 in 1995, $6,527 in 1994, and $1,440
in 1993, and are included in net revenues. Effective January 1, 1994, BMS agreed
to reimburse the Partnership for certain financing costs and General Electric
Capital Corporation ("GECC") fees. In 1994, such reimbursement totaled $3,817,
of which $2,978 is included in other nonoperating income and expense for the
period during which the GECC agreements were in effect, and $839 in 1994 and
$2,752 in 1995 are included as an offset to interest expense for the period
subsequent to the termination of the GECC agreements.

The Partnership has a term of 20 years, but can be terminated earlier at BMS'
option upon one year's notice as of January 1, 2003 or January 1, 2008. In
addition, the right to terminate the partnership agreement and the Sales Agency
Agreement arises under certain circumstances, including breach, bankruptcy,
insolvency, a change in control of Axion or the general partner or the sale by
the general partner of its interest in the Partnership. Under certain
conditions, upon termination of the partnership agreement, the terminating
partner is entitled to purchase the other partner's interest or to require the
other partner to purchase the terminating partner's interest. In addition, in
the event that the Sales Agency Agreement is terminated as a result of a change
in control of Axion, or BMS elects to terminate the Sales Agency Agreement in
2003 or 2008, BMS is required to sell, and Axion is required to buy, BMS'
interest.

OTNC receives a preferential allocation of profits as follows: in 1993, the
first $900 in profits would have been allocated to OTNC if the Partnership had
earned profits, with the balance allocated 80% to OTNC and 20% to the limited
partner; in 1994, this preference was $4,900 with the balance allocated 80:20 in
favor of OTNC; in 1995, the preference was $10,200 with the balance allocated
80:20; in 1996, the preference is $18,750 with the balance allocated 80:20; in
1997, all profits are allocated 70:30; in 1998, 60:40; and after 1998 all
profits are allocated equally.

   
The preferences due OTNC are cumulative; any unallocated preference is carried
forward for allocation in later years, together with interest at the prime rate
on the accumulated unpaid preference. The aggregate preference of OTNC over the
term of the Partnership, excluding interest, is $34,750 ($35,800 including
interest) of which $4,788 in 1995 was paid to OTNC as a distribution. Generally,
all losses are borne equally by both partners throughout the term of the
Partnership provided that BMS shall not be allocated losses that cause its
capital account to be negative.
    

OTNC was allocated a loss of $996, or 50% of the Partnership's loss in the 1993
period, income of $4,788, or 100% of the Partnership's profit in 1994, and
income of $11,083, or 100% of the Partnership's profit in 1995.

5. Financing of Accounts Receivable and Inventories

Prior Arrangements

GECC Agreement (no longer in effect)

In 1993, to facilitate the provision of credit to its customers and to reduce
the requirement for further working capital financing, the Partnership and BMS
entered into agreements with GECC for the sale of eligible accounts receivable
(both BMS and non-BMS product related), subject to a 25% cash holdback by GECC
of the uncollected balance. Proceeds from the sale of BMS and non-BMS product
receivables were remitted directly by GECC to the Partnership, less the
holdback. In 1994, the Partnership incurred $3,310 of GECC fees related to the
sale of BMS receivables and $1,952 of GECC fees related to the sale of non-BMS
products. In 1993, the Partnership incurred $870 of GECC fees related to the
sale of BMS receivables and $537 of GECC fees related to the sale of non-BMS
products. BMS reimbursed the Partnership for certain GECC fees in 1994 and such
reimbursement totaled $2,317. GECC fees, net of reimbursement by BMS, are
included under other nonoperating expense in the statements of operations.

          (in thousands of dollars, except share and per share amounts)

BMS Agreement (no longer in effect)

In September 1994, the Partnership and BMS terminated the agreements with GECC.
Interim financing was then provided by the partners and ultimately by BMS under
a $30,000 secured note agreement payable in full on January 31, 1995. The
$30,000 note was paid in January 1995 out of the initial borrowings under the
bank credit line discussed below.

Current Arrangement - $50,000 Bank Credit Line

In January 1995, the Partnership entered into agreements to establish a $50,000
one year revolving line of credit with a bank. The bank credit line is renewable
annually, if the parties so agree. The current expiration date is December 31,
1996. Interest is payable monthly at interest rates ranging from .25% to .75%
above the bank's reference rate, unless the Partnership elects an optional
interest rate of 0.50% above the bank's offshore rate as defined in the
agreement (6.3% at December 31, 1995). The agreement includes certain covenants
which restrict the Partnership's use of amounts borrowed and its ability to
incur additional obligations and pay distributions. Additionally, certain
covenants of the loan agreement require the Partnership to maintain tangible net
worth and a ratio of liabilities to tangible net worth at determined levels. At
December 31, 1995, Axion had borrowed $35,617 under this agreement. The
borrowings are secured by the Partnership's inventories and accounts receivable.

6. Product Development

In 1992, Axion initiated a product development program whereby it would acquire
rights to certain drug compounds from third parties in exchange for various
payments and development funding. In August 1993, Axion terminated its product
development activities in order to focus its efforts on the development of the
Partnership and the support of clinical studies.

7. Commitments

Axion has an agreement to lease its existing office facility through July 1996.
Rent expense under this lease was $276, $333 and $368 in 1993, 1994 and 1995,
respectively. Minimum future lease payments under this operating lease are $214
in 1996.

Axion has an agreement for management information services through December
2004. Future payments under this agreement are as follows: $2,375 in 1996;
$2,452 in 1997; $2,502 in 1998; $2,552 in 1999; $2,552 in 2000; and $9,120
thereafter.

Convertible Preferred Stock (continued)

Any assets remaining after payment of liquidation preferences plus any declared
but unpaid dividends to the holders of the convertible preferred stock would be
distributed pro rata to holders of common and preferred shares on an
as-converted basis until the preferred shareholders of Series A, B, C and E
receive an aggregate of $4.00, $7.00, $7.00 and $9.46 per share, respectively,
inclusive of the respective liquidation preference amounts referred to above.
Thereafter, the remaining assets would be distributed pro rata among the holders
of common shares.

Holders of convertible preferred stock are entitled to noncumulative cash
dividends if and when declared by the Board of Directors. No dividends have been
declared through December 31, 1995.

Warrants

At December 31, 1995, warrants to purchase 25,000 shares of common stock were
outstanding at $6.00 per share. The warrants expire in June 2005.

Stock Option and Restricted Stock Plan

Axion has a Stock Option and Restricted Stock Plan (the "1989 Plan") under which
a total of 2,000,000 shares of common stock have been reserved for issuance to
employees, including officers and directors, nonemployee directors and
consultants of Axion. Incentive options may be granted at a price per share not
less than the fair value of common stock on the date of grant and become
exercisable in increments over periods of one to four years from the date of
grant. Non-qualified options may be granted at a price per share not less than
85% of fair value on the date of grant and become exercisable in increments over
periods of one to five years.

In 1995, Axion allowed employees to cancel certain outstanding options and
receive new grants for a like number at the fair value of the common stock on
the date of grant. Employees elected to cancel and receive new grants for
options on 161,250 shares.

The following table summarizes the option activity under the 1989 Plan for the
years ended December 31, 1995, 1994 and 1993:

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
Axion's deferred tax liabilities and assets as of December 31, are as follows:

The significant reconciling item in the reconciliation of income tax computed at
the U.S. federal statutory tax rate to the provision for income tax expense is
the reduction in the valuation allowance for deferred tax assets in 1995 as a
result of the utilization of net operating loss carryforwards.
   
10. Benefit Plan

Axion has a defined contribution plan under the provisions of Section 401(k) of
the Internal Revenue Code covering all eligible employees (the "401(k) Plan").
Employees may contribute to the 401(k) Plan annually up to the Internal Revenue
Service limit. The Plan allows Axion to make matching contributions at the
discretion of the Board of Directors. Axion has not contributed to the 401(k)
Plan since its inception.

11. Proposed Merger with BMS and Distribution of AHC to Shareholders

As of August 2, 1996, Axion and BMS signed an amended and restated agreement and
plan of merger, which contemplates the merger of a newly formed wholly owned
subsidiary of BMS into Axion, with Axion being the surviving company. Holders of
shares of Axion's common stock at the consummation of the proposed merger would
receive shares of common stock of BMS having an aggregate value of $86,000,
subject to holdback of shares of common stock of BMS having a value of $5,000.
The $5,000 in shares of common stock of BMS plus $5,000 in cash otherwise
available to AHC will constitute an escrow fund to secure indemnification
obligations to BMS in the event BMS were to suffer certain defined indemnifiable
losses. Prior to consummation, all the shares of Axion's various series of
preferred stock will be converted into shares of Axion common stock and all of
the options and warrants outstanding to purchase shares of Axion common stock
will be either exercised (including that portion of options that would not yet
be exercisable under normal circumstances) or cancelled. Axion intends to extend
loans to holders of Axion stock options and warrants to assist those holders in
paying for the shares purchased upon exercise of options and warrants. Based on
Axion's shares of preferred and common stock outstanding at December 31, 1995
and shares of common stock subject to unexercised stock options and warrants at
December 31, 1995, the pro forma number of shares of Axion common stock at that
date, assuming full conversion of shares of preferred stock and exercise of
substantially all outstanding options and warrants, would have been 9,977,756
shares (excluding

11. Proposed Merger with BMS and Distribution of AHC to Shareholders (continued)

100,000 shares of Axion common stock pursuant to an option which is not expected
to be exercised). The actual exchange ratio of shares of BMS common stock for
shares of Axion common stock will be a fraction determined by: (i) the aggregate
value of $86,000, divided by the average closing market price of shares of BMS
common stock during the ten trading days ending five trading days prior to the
consummation of the merger (subject to both a minimum price and a maximum
price); divided by (ii) the number of shares of Axion common stock at
consummation of the merger, assuming full conversion of shares of preferred
stock and exercise of options and warrants for shares of common stock.

Immediately prior to consummation of the merger, Axion intends to distribute to
its then stockholders all of the outstanding shares of stock of AHC, which will
represent 100% ownership in AHC. AHC will have received from Axion, as a
contribution to the capital of AHC, substantially all of Axion's assets and
liabilities other than those assets and liabilities related to Axion's interest
in the Partnership and of the OPUS Station automated drug dispensing business.
Among the more significant assets to be transferred to AHC by Axion will be: (i)
a cash distribution from the Partnership to Axion of $13,615 (which would have
required additional borrowings by the Partnership of $9,226 at December 31,
1995), and the remainder of Axion's cash and cash equivalents and short-term
investments ($9,132 at December 31, 1995), subject to adjustment in certain
situations, of which $5,000 will be placed in an escrow fund as previously
disclosed; (ii) the shares of Series A redeemable preferred stock of OnCare
($3,500 representing 700,000 shares at December 31, 1995, which was increased by
$10,000, representing an additional 2,000,000 shares, in February and March
1996, making a total of $13,500 or 2,700,000 shares); and (iii) amounts due
under loans extended to those persons exercising Axion stock options and
warrants (none at December 31. 1995, but approximately $6,500 at that date had
substantially all of the options and warrants then outstanding been exercised
and loans extended for the full exercise price).

The merger of Axion and the newly formed BMS subsidiary is subject to certain
conditions including approval by the holders of Axion's various classes of
stock, regulatory matters and certain other conditions.

Historical operating results of Axion including the Partnership and the OPUS
Station automated drug dispensing business, which constitute the businesses (the
"Retained Business" upon consummation of the merger) to be merged with the newly
formed wholly owned subsidiary of BMS are shown below. In 1995, the operating
results below exclude OnCare, which was formed in June 1995 and the shares of
common stock of which were distributed by Axion Inc. on December 31, 1995, AHC
and the OPUS Matrix business, together the businesses to be distributed to Axion
shareholders (the "Acquired Business") immediately prior to consummation of the
merger. For the 1993 and 1994 operating results below, no adjustments have been
made to Axion's historical results as they would be insignificant.

              Notes to Condensed Consolidated Financial Statements
          (in thousands of dollars, except share and per share amounts)

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the six-month period ended June 30, 1996
are not necessarily indicative of the results that may be expected for the year
ended December 31, 1996. For further information, refer to the consolidated
financial statements for each of the three years in the period ended December
31, 1995 and footnotes thereto included on pages F-3 to F-20.

2. Interest in OnCare

    
   

In February and March 1996, Axion advanced an additional $10,000 to OnCare Inc.
("OnCare") in exchange for an additional 2,000,000 shares of OnCare Series A
redeemable preferred stock to be issued, increasing its interest in the Series A
preferred stock to $13,500, representing 2,700,000 shares. OnCare is obligated
to redeem the Series A preferred stock at a redemption price of $5 per share at
the earlier of December 31, 2000, the closing of a qualifying underwritten
public offering of the common stock in OnCare, the merger or consolidation of
OnCare with or into another corporation, or the sale of all or substantially all
of OnCare's assets.


OnCare ceased to be a consolidated subsidiary on December 31, 1995, as a result
of the distribution by Axion of its holdings of the common stock of OnCare.
Operating results of OnCare for the six months ended June 30, 1996 are not
included in Axion's consolidated statement of income for that period. Revenues
of OnCare for the six months ended June 30, 1996 were $7,118 and its net loss
was $1,175, without any income tax benefit. The condensed financial position of
OnCare at June 30, 1996 and Axion's investment are summarized as follows:

3. Proposed Merger with BMS and Distribution of AHC to Shareholders
   
As of August 2, 1996, Axion and BMS signed an amended and restated agreement and
plan of merger, which contemplates the merger of a newly formed wholly owned
subsidiary of BMS into Axion, with Axion being the surviving company. Holders of
shares of Axion's common stock at the consummation of the proposed merger would
receive shares of common stock of BMS having a value of $86,000, subject to
holdback of shares of common stock of BMS having a value of $5,000. The $5,000
in shares of common stock of BMS plus $5,000 in cash otherwise available to AHC
will constitute an escrow fund to secure indemnification obligations to BMS in
the event BMS were to suffer certain defined indemnifiable losses. Prior to
consummation, all the shares of Axion's various series of preferred stock will
be converted into shares of Axion common stock and all of the options and
warrants outstanding to purchase shares of Axion common stock will be either
exercised (including that portion of options that would not yet be exercisable
under normal circumstances) or cancelled. Axion intends to extend loans to
holders of Axion stock options and warrants to assist those holders in paying
for the shares purchased upon exercise of options and warrants. Based on Axion's
shares of preferred and common stock outstanding at June 30, 1996 and shares of
common stock subject to unexercised stock options and warrants at June 30, 1996,
the pro forma number of shares of Axion common stock at that date, assuming full
conversion of shares of preferred stock and exercise of substantially all
outstanding options and warrants, would have been 9,977,756 shares (excluding
100,000 shares of Axion common stock pursuant to an option which is not expected
to be exercised). The actual exchange ratio of shares of BMS common stock for
shares of Axion common stock will be a fraction determined by: (i) the aggregate
value of $86,000, divided by the average closing market price of shares of BMS
common stock during the ten trading days ending five trading days prior to the
consummation of the merger (subject to both a minimum price and a maximum
price); divided by (ii) the number of shares of Axion common stock at
consummation of the merger, assuming full conversion of shares of preferred
stock and exercise of options and warrants for shares of common stock.

Immediately prior to consummation of the merger, Axion intends to distribute to
its then stockholders all of the outstanding shares of stock of AHC, which will
represent 100% ownership in AHC. AHC will have received from Axion, as a
contribution to the capital of AHC, substantially all of Axion's assets and
liabilities other than those assets and liabilities related to Axion's interest
in the Partnership and the OPUS station automated drug dispensing and inventory
tracking systems business. Among the more significant assets to be transferred
to AHC by Axion will be: (i) a cash distribution from the Partnership to Axion
of $13,615 (which would have required additional borrowings by the Partnership
of $12,915 at June 30, 1996), and the remainder of Axion's cash and cash
equivalents and short-term investments ($2,485 at June 30, 1996), subject to
adjustment in certain situations, of which $5,000 will be placed in an escrow
fund as previously disclosed; (ii) the shares of Series A redeemable preferred
stock of OnCare (2,700,000 shares with a redemption value and carrying cost of
$13,500); and (iii) amounts due under loans extended to those persons exercising
Axion stock options and warrants (none at June 30, 1996, but approximately
$6,500 at that date had substantially all of the options and warrants then
outstanding been exercised and loans extended for the full exercise price).
    
The merger of Axion and the newly formed BMS subsidiary is subject to certain
conditions including approval by the holders of Axion's various classes of
stock, regulatory matters and certain other conditions.

3. Proposed Merger with BMS and Distribution of AHC to Shareholders (continued)

Historical operating results of Axion including the Partnership and the OPUS
Station automated drug dispensing and inventory tracking systems business, which
constitute the businesses (the "Retained Business" upon consummation of the
merger) to be merged with the newly formed wholly owned subsidiary of BMS are

business, the businesses to be distributed to Axion shareholders (the "Acquired
Business") immediately prior to consummation of the merger.

3. Proposed Merger with BMS and Distribution of AHC to Shareholders (continued)
   
The historical financial position of the Retained Business to be merged with the
newly formed wholly owned subsidiary of BMS is shown below. The historical
financial position does not reflect the transfer to AHC by Axion of: (i) a cash
distribution from the Partnership to Axion of $13,615, (which would have
required additional borrowings by the Partnership of $12,915 at June 30,1996)
and the remainder of Axion's cash and cash equivalents and short-term
investments ($2,485 at June 30, 1996), subject to adjustment in certain
situations, of which $5,000 will be placed in an escrow fund; and (ii) the
shares of Series A redeemable preferred stock of OnCare ($13,500 representing
2,700,000 shares at June 30, 1996); and (iii) the effect of exercise of
unexercised Axion stock options and warrants (and related loans receivable and
cash received) arising after June 30, 1996.

                                       and
                          Axion HealthCare Inc. ("AHC")

                Notes to Pro Forma Condensed Financial Statements
                            (in thousands of dollars)

1. Proposed Distribution of all Stock of AHC to Stockholders of Axion

Immediately prior to consummation of the merger of a subsidiary of BMS with
Axion Inc. ("Axion"), Axion intends to distribute to its then stockholders all
of the outstanding shares of Axion HealthCare Inc. ("AHC"), which will represent
100% ownership in AHC. Prior to that distribution, AHC will have received from
Axion, as a contribution to the capital of AHC, substantially all of Axion's
assets and liabilities other than those assets and liabilities related to
Axion's interest in the Partnership and the OPUS station automated drug
dispensing business. Among the more significant assets to be transferred to AHC
by Axion will be (i) a cash distribution from the Partnership to Axion of
$13,615 (which would have required additional borrowings by the Partnership of
$12,915 at June 30, 1996) and the remainder of Axion's cash and cash equivalents
and short-term investments ($2,485 at June 30, 1996), subject to adjustment in
certain situations, of which $5,000 will be placed in an escrow fund (as
discussed below); (ii) the shares of Series A redeemable preferred stock of
OnCare (2,700,000 shares with a redemption value and cost of $13,500); and (iii)
amounts due under loans extended to those persons exercising Axion stock options
and warrants (none at June 30, 1996, but approximately $6,500 at that date had
substantially all of the options and warrants then outstanding been exercised
and loans extended for the full exercise price).

2. Pro Forma Condensed Balance Sheets

The pro forma condensed balance sheets give effect to the distribution of AHC by
Axion, after the transfer from Axion to AHC of: (i) a cash distribution from the
Partnership to Axion of $13,615 (which would have required additional borrowings
by the Partnership of $12,915 at June 30, 1996) and $2,485 of cash and cash
equivalents and short-term investments at June 30, 1996 (representing the
remainder of Axion's cash and cash equivalents and short-term investments),
subject to adjustment in certain situations, of which $5,000 will be placed in
an escrow fund (as discussed below); and (ii) $13,500 redemption and carrying
value of the 2,700,000 shares of Series A redeemable preferred stock of OnCare.
The pro forma condensed balance sheets do not reflect the transfer of loans
receivable (none at June 30, 1996 but approximately $6,500 at that date had
substantially all of the options and warrants then outstanding been exercised
and loans extended for the full exercise price) from Axion to AHC.
    

Upon consummation of the proposed merger of Axion with BMS, $5,000 of cash of
AHC will be deposited in an escrow fund to secure indemnification obligations to
BMS in the event BMS were to suffer certain defined indemnifiable losses from
its merger with Axion. The segregation of this amount of cash is not reflected
in the pro forma condensed balance sheets.

3. Pro Forma Condensed Income Statements

The pro forma condensed income statements give effect to the separation of
OnCare and AHC from Axion, as if the common stock of both OnCare and AHC had
been distributed by Axion prior to 1995. The losses of OnCare and AHC would not
have been available to be used in Axion's income tax returns and there would
have been no current income tax benefit from these losses, had the distribution
been made prior to 1995.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware  General  Corporation Law (the "DGCL")  provides
that a  corporation  may  indemnify  directors  and  officers  as well as  other
employees  and  individuals  against  expenses   (including   attorneys'  fees),
judgments,  fines and amounts paid in settlement in  connection  with  specified
actions,  suits or  proceedings,  whether  civil,  criminal,  administrative  or
investigative  (other  than an  action  by or in the  right of the  corporation,
hereinafter a "derivative action"), if such persons acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation and, with respect to any criminal actions or proceedings, had no
reasonable  cause to believe their conduct was unlawful.  A similar  standard is
applicable in the case of derivative actions,  except that  indemnification only
extends to expenses (including attorneys' fees) actually and reasonably incurred
in  connection  with the  defense or  settlement  of such  action,  and the DGCL
requires court approval before there can be any indemnification where the person
seeking  indemnification  has been found liable to the corporation.  Pursuant to
its terms, the DGCL is not exclusive of other rights to indemnification that may
be granted by a corporation's by-laws,  disinterested director vote, stockholder
vote, agreement or otherwise.

    Under the terms of the  Registrant's  By-laws,  each director and officer is
indemnified by the Registrant, to the full extent permitted by law, against: (i)
expenses  incurred  or paid by the  director or officer in  connection  with any
claim made against such director or officer, or any actual or threatened action,
suit or proceeding  (civil,  criminal,  administrative,  investigative or other,
including appeals and whether or not relating to a date prior to the adoption of
this  by-law) in which such  director  or officer  may be involved as a party or
otherwise,  by reason of being or  having  been a  director  or  officer  of the
Registrant, or of serving or having served at the request of the Registrant as a
director, officer, employee, or agent of another corporation, partnership, joint
venture,  trust or other  enterprise,  or by reason of any  action  taken or not
taken by such  director  or  officer  in such  capacity,  and (ii) the amount or
amounts paid by the director or officer in settlement of any such claim, action,
suit  or  proceeding  or  any  judgment  or  order  entered  therein;   however,
notwithstanding  anything to the contrary in the Registrant's  By-laws,  where a
director  or officer  seeks  indemnification  in  connection  with a  proceeding
voluntarily  initiated by such director or officer the right to  indemnification
granted  thereunder  shall be limited to  proceedings  where  such  director  or
officer has been wholly successful on the merits. The term "expenses"  includes,
but  is  not  limited  to,  reasonable   amounts  for  attorneys'  fees,  costs,
disbursements and other expenses and the amount or amounts of judgments,  fines,
penalties and other liabilities.

    Article Fourteenth of the Registrant's Restated Certificate of Incorporation
provides  that  subject  to the  provisions  of the  DGCL,  no  director  of the
Registrant shall be personally  liable to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty as a director except to the extent
that such liability  arises (i) from a breach of the director's  duty of loyalty
to the Registrant or its stockholders, (ii) as a result of acts or omissions not
in good faith or which involve intentional  misconduct or a knowing violation of
law,  (iii) under Section 174 of the DGCL relating to unlawful stock purchase or
redemption or (iv) any transaction  from which the director  derived an improper
personal benefit.

ITEM 21.  EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

    The  exhibits  and  financial   statement  schedules  to  this  Registration
Statement  are  listed  in the  Exhibit  Index  which  immediately  follows  the

ITEM 22.  UNDERTAKINGS.

    A. Insofar as indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final jurisdiction of
such issue.

    B. The  undersigned  Registrant  hereby  undertakes  that,  for  purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    C. The undersigned  Registrant hereby  undertakes as follows:  that prior to
any public  reoffering of the securities  registered  hereunder through use of a
prospectus  which is a part of this  Registration  Statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed  underwriters,  in addition to the information  called
for by the other Items of the applicable form.

    D.  The  Registrant  undertakes  that  every  prospectus:  (i) that is filed
pursuant to paragraph (C) immediately  preceding,  or (ii) that purports to meet
the  requirements of Section  10(a)(3) of the Act and is used in connection with
an offering  of  securities  subject to Rule 415,  will be filed as a part of an
amendment  to the  Registration  Statement  and  will  not be  used  until  such
amendment is  effective,  and that,  for purposes of  determining  any liability
under the Securities Act of 1933,  each such  post-effective  amendment shall be
deemed to be a new registration  statement  relating to the securities  offering
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

    E. The undersigned  Registrant  hereby undertakes to respond to requests for
information  that is incorporated  by reference into the prospectus  pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request,  and to send the  incorporated  documents  by first class mail or other
equally prompt means. This includes information contained in the documents filed
subsequent to the effective date of the Registration  Statement through the date
of responding to the request.

    F. The  undersigned  Registrant  hereby  undertakes  to supply by means of a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  involved  therein,  that  was not the  subject  of and
included in the Registration Statement when it became effective.

    G.  The undersigned Registrant hereby undertakes:

        1. To file during any period in which offers and sales are being made, a
     post-effective amendment to this Registration Statement:

           a. To include  any  prospectus  required  by Section  10(a)(3) of the
        Securities Act of 1933;

                                      II-2




 
<PAGE>
 

<PAGE>




           b. To reflect in the prospectus any facts or events arising after the
        effective  date  of the  Registration  Statement  (or  the  most  recent
        post-effective   amendment  thereof)  which,   individually  or  in  the
        aggregate,  represent a fundamental  change in the information set forth
        in the Registration Statement; and

           c. To include any  material  information  with respect to the plan of
        distribution not previously  disclosed in the Registration  Statement or
        any material change to such information in the Registration Statement.

        2.  That  for  the  purpose  of  determining  any  liability  under  the
    Securities Act of 1933, each such  post-effective  amendment shall be deemed
    to be a new  registration  statement  relating  to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

        3. To remove from  registration by means of a  post-effective  amendment
    any  of  the  securities   being  registered  which  remain  unsold  at  the
    termination of the offering.

                                      II-3

following the Contributions and immediately prior to the Time of Distribution,
(i) each issued and outstanding share of AHC Common Stock, par value $.0001 per
share ("AHC Common Stock"), will be converted into a number of shares of AHC
Series A Preferred Stock, par value $.0001 per share ("AHC Preferred Stock") as
shall be equal to the quotient of (A)(I) the number of shares of Axion Common
Stock, par value $.001 per share ("Axion Common Stock"), outstanding immediately
prior to the Time of Distribution (including any shares of Axion Common Stock
issued in connection with the exercise of Axion Options (as defined in Section
6.06) in connection with the consummation of the Merger) plus (II) the number of
shares of Axion Common Stock to be issued in connection with the conversion of

Preferred Stock all the then outstanding shares of AHC Preferred Stock (the
"Distribution");

            WHEREAS, the respective Boards of Directors of BMS and Axion have
determined that, following the Distribution, the merger of BMS Sub with and into
Axion (the "Merger") with Axion as the surviving corporation (the "Surviving
Corporation") upon the terms and subject to the conditions set forth in this
Agreement would be advantageous and beneficial to their respective corporations
and stockholders; and

            WHEREAS, for Federal income tax purposes, it is intended that (a)
the Distribution shall qualify as a tax-free spinoff under Section 355 of the
Internal Revenue Code of 1986, as amended (the "Code") and (b) the Merger

reorganization.

            NOW, THEREFORE, in consideration of the representations, warranties,

(subject to satisfaction or waiver of the conditions set forth in Article VII)
shall be no later than the first business day after satisfaction of the
conditions set forth in Article VII (other than those that are waived by the
party or parties for whose benefit such conditions exist) (the "Closing Date"),
at the offices of Cravath, Swaine & Moore, Worldwide Plaza, 825 Eighth Avenue,
New York, N.Y. 10019, unless another date or place is agreed to in writing by
the parties hereto.

            SECTION 1.04. Effects of the Merger. The Merger shall have the
effects set forth in Section 259 of the DGCL. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time, all the properties,

Corporation, and all debts, liabilities and obligations of Axion shall become
the debts, liabilities and obligations of the Surviving Corporation.

            SECTION 1.05. Certificate of Incorporation and By-Laws. (a) The
Certificate of Incorporation of Axion shall be the Certificate of Incorporation
of the Surviving Corporation until thereafter changed or amended as provided
therein or by applicable law.

            (b) The By-laws of Axion as in effect at the Effective Time shall be
the By-laws of the Surviving Corporation until thereafter changed or amended as
provided therein or by applicable law.

            SECTION 1.06. Directors. The directors of BMS Sub at the Effective
Time shall be the directors of the Surviving Corporation, until the earlier of
their resignation or removal or until their respective successors are duly
elected and qualified, as the case may be.

                                   ARTICLE II

                Effect of the Merger on the Capital Stock of the
               Constituent Corporations; Exchange of Certificates

            SECTION 2.01. Effect on Capital Stock. As of the Effective Time, by
virtue of the Merger and without any further action on the part of the holder of

            (a) Cancelation of Treasury Stock, Axion-Owned Stock and BMS-Owned
Stock. Each share of Axion Common Stock issued and outstanding immediately prior
to the Effective Time and owned by Axion or by any of its Subsidiaries owned

                                                                               5


by BMS or any wholly owned subsidiary of BMS or held in the treasury of Axion
shall automatically be canceled and retired and shall cease to exist, and no BMS
Common Stock (as defined in Section 2.01(b)) or other consideration shall be
delivered in exchange therefor.

            (b) Conversion of Axion Common Stock. (i) Subject to Section
2.02(e), each issued and outstanding share of Axion Common Stock (other than (A)
shares to be canceled in accordance with Section 2.01(a) and (B) as set forth in
paragraph (d) below, shares that have not been voted in favor of the approval
and adoption of this Agreement and with respect to which appraisal rights shall
have been perfected in accordance with Section 262 of the DGCL ("Dissenters'
Shares")) shall be converted into the right to receive a number of fully paid
and nonassessable shares of Common Stock, par value $.10 per share, of BMS
together with the associated rights pursuant to the Rights Agreement dated as of
December 4, 1987, as amended on July 26, 1989, between BMS and The Chase
Manhattan Bank, as Rights Agent, (collectively, "BMS Common Stock") equal to the
Conversion Number (the "Merger Consideration"). The term "Conversion Number"
shall mean a number (rounded to the nearest thousandth or, if there shall not be
a nearest thousandth, rounded to the next higher thousandth), equal to the
quotient of (a)(i) $86,000,000 divided by (ii) the Average Value of BMS Common
Stock divided by (b) the number of shares of Axion Common Stock outstanding
immediately prior to the Effective Time (calculated on a fully diluted basis
assuming all shares of Axion Preferred Stock outstanding immediately prior to
the Effective Time have been converted into Axion Common Stock in accordance
with the terms of such Axion Preferred Stock and all Axion Options outstanding
immediately prior to the Effective Time have been exercised or canceled and in
each case the related subject shares of Axion Common Stock (other than any
subject shares related to any portion of any Axion Option that shall have been
canceled and not exercised) are outstanding). The term "Average Value of BMS
Common Stock" means an amount equal to the average of the per share closing
prices of BMS Common Stock as reported on the New York Stock Exchange Composite
Transaction Tape (as published in The Wall Street Journal, Eastern Edition, or,
if not published therein, in another authoritative source mutually selected by
Axion and BMS) for the 10 consecutive full New York Stock Exchange ("NYSE")
trading days ending on the fifth full NYSE trading day immediately preceding the
Effective Time; provided that (A) if the Board of Directors of BMS declares a
cash

                                                                               6


dividend on the outstanding shares of BMS Common Stock having a record date
after the Effective Time but an exdividend date (based on "regular way" trading
on the NYSE of shares of BMS Common Stock, the "Ex-Date") that occurs during the
averaging period, then for purposes of computing the Average Value of BMS Common
Stock, the closing price on the Ex-Date and any trading day in the averaging
period after the Ex-Date shall be adjusted by adding thereto the amount of such
dividend and (B) if the Board of Directors of BMS declares a cash dividend on
the outstanding shares of BMS Common Stock having a record date before the
Effective Time and an Ex-Date that occurs during the averaging period, then for
purposes of computing the Average Value of BMS Common Stock, the closing price
on any trading day before the Ex-Date will be adjusted by subtracting therefrom
the amount of such dividend. Notwithstanding anything to the contrary contained
herein, in the event that the Average Value of BMS Common Stock on the Closing
Date is less than $82.73 (the "Minimum Price"), then solely for the purposes of
calculating the Merger Consideration, the Average Value of BMS Common Stock on
the Closing Date shall be deemed to be the Minimum Price, and in the event that
the Average Value of BMS Common Stock on the Closing Date is greater than $91.43
(the "Maximum Price"), then solely for the purposes of calculating the Merger
Consideration, the Average Value of BMS Common Stock on the Closing Date shall
be deemed to be the Maximum Price. If prior to the Effective Time, the Board of
Directors of BMS declares a stock split, stock combination, stock dividend or
other non-cash distribution on the outstanding shares of BMS Common Stock, then
the Minimum Price and Maximum Price (and if the Ex-Date for such event occurs
during the Averaging Period, the Average Value of BMS Common Stock) will be
appropriately adjusted to reflect such split, combination, dividend or other
distribution. As of the Effective Time, all such shares of Axion Common Stock
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each holder of a certificate representing any such
shares of Axion Common Stock shall cease to have any rights with respect
thereto, except the right to receive the shares of BMS Common Stock and any cash
in lieu of fractional shares of BMS Common Stock to be issued or paid in
consideration therefor upon surrender of such certificate in accordance with
Section 2.02, without interest.

            (ii) The term "Axion Expenses" shall mean all out-of-pocket fees and
expenses incurred or to be incurred

                                                                               7


by or on behalf of Axion or any of its Subsidiaries in connection with the
Merger, the Distribution or the consummation of any of the transactions
contemplated by this Agreement and the Documents (as defined in Section 9.03(b))
and the negotiation, preparation, review and delivery of the agreements
contemplated hereby and thereby, including all Axion's expenses incurred or to
be incurred by Axion or any such Subsidiary in connection with printing and
mailing the Required AHC Documents (as defined in Section 4.01(d)) other than
the Proxy Statement (as defined in Section 4.01(d)) and, subject to the
provisions of Section 6.07, the Proxy Statement and the Form S-4 (as defined in
Section 4.01(f)) and all fees and expenses incurred or to be incurred by Axion
or any such Subsidiary of accountants, legal counsel, investment bankers and
other advisors. Axion shall cause third parties to submit to Axion not later
than five business days prior to Closing final bills for all Axion Expenses, and
Axion shall submit to BMS not later than five business days prior to Closing a
true and complete schedule of all Axion Expenses (the "Transaction Expense
Schedule"), together with a copy of all invoices or other supporting
documentation related thereto and a copy of all final bills issued for Axion
Expenses.

            (c) Conversion of BMS Sub Common Stock. As of the Effective Time, by
virtue of the Merger, each issued and outstanding share of capital stock of BMS
Sub shall be converted into and become one fully paid and nonassessable share of
Common Stock, par value $.010 per share, of the Surviving Corporation.

            (d) Shares of Dissenting Stockholders. Notwithstanding anything in
this Agreement to the contrary, no Dissenters' Shares shall be converted as
described in Section 2.01(b) but shall become the right to receive such
consideration as may be determined to be due in respect of such Dissenters'
Shares pursuant to the laws of the State of Delaware; provided, however, that
any Dissenters' Shares outstanding immediately prior to the Effective Time and
held by a stockholder who shall, after the Effective Time, lose his or her right
of appraisal, withdraw his or her demand for appraisal as a matter of right
under Section 262 of the DGCL, or, with the consent of BMS, otherwise withdraw
his or her demand for appraisal, in either case pursuant to the DGCL, shall be
deemed to be converted as of the Effective Time into the right to receive the
Merger Consideration. Axion shall give BMS prompt notice of any written demands
for appraisal of shares of Axion Common Stock received by

                                                                               8


Axion. Axion shall not, without the prior written consent of BMS, make any
payment with respect to, or settle, offer to settle or otherwise negotiate, any
such demands. Payments, if any, with respect to Dissenters' Shares shall not be
paid by BMS or with funds supplied by BMS.

            SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. As of
the Effective Time, BMS shall deposit with Chemical Mellon Shareholders Services
LLC or a bank or trust company appointed by BMS (the "Exchange Agent"), for the
benefit of the holders of shares of Axion Common Stock, for exchange in
accordance with this Article II, through the Exchange Agent, certificates
representing the shares of BMS Common Stock (such shares of BMS Common Stock,
together with any dividends or distributions with respect thereto, being
hereinafter referred to as the "Exchange Fund") issuable pursuant to Section
2.01 in exchange for outstanding shares of Axion Common Stock. BMS shall provide
to the Exchange Agent, on a timely basis, funds necessary to pay any cash
payable in lieu of fractional shares of BMS Common Stock.

            (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, BMS shall cause the Exchange Agent to mail to each holder of
record of a certificate or certificates which immediately prior to the Effective
Time represented outstanding shares of Axion Common Stock (the "Certificates")
whose shares were converted into the right to receive shares of BMS Common Stock
pursuant to Section 2.01, (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Exchange Agent and shall be
in such form and have such other provisions as BMS may reasonably specify
including the terms set forth in the letter of transmittal attached hereto as
Exhibit I (the "Letter of Transmittal")) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of BMS Common Stock. Upon surrender of a Certificate for
cancelation to the Exchange Agent or to such other agent or agents as may be
appointed by BMS, together with such Letter of Transmittal, duly executed, and
such other documents as may reasonably be required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor a
certificate representing that number of whole shares of BMS Common Stock which
such holder has the right to receive pursuant to the provisions of this Article
II

                                                                               9


(which, for the avoidance of doubt, shall not include the number of shares of
BMS Common Stock that shall be deemed to have been deposited in escrow by such
holder in accordance with the provisions of Section 2.02(i)(e)), and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of Axion Common Stock which is not registered in the
transfer records of Axion, a Certificate representing the proper number of
shares of BMS Common Stock may be issued to a person other than the person in
whose name the Certificate so surrendered is registered, if such Certificate
shall be properly endorsed or otherwise be in proper form for transfer and the
person requesting such payment shall pay any transfer or other taxes required by
reason of the issuance of shares of BMS Common Stock to a person other than the
registered holder of such Certificate or establish to the satisfaction of BMS
that such tax has been paid or is not applicable. Until surrendered as
contemplated by this Section 2.02, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the certificate representing shares of BMS Common Stock and cash in
lieu of any fractional shares of BMS Common Stock as contemplated by this
Section 2.02. No interest will be paid or will accrue on any cash payable in
lieu of any fractional shares of BMS Common Stock.

            (c) Distributions with Respect to Unexchanged Shares. No dividends
or other distributions with respect to BMS Common Stock with a record date after
the Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of BMS Common Stock represented thereby, and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to Section 2.02(e) until the surrender of such Certificate in accordance with
this Article II. Subject to the effect of applicable laws, following surrender
of any such Certificate, there shall be paid to the holder of the Certificate
representing whole shares of BMS Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender, the amount of any cash
payable in lieu of a fractional share of BMS Common Stock to which such holder
is entitled pursuant to Section 2.02(e) and the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid with

BMS Common Stock issued upon the surrender for exchange of Certificates in

theretofore represented by such Certificates, and there shall be no further
registration of transfers on the stock transfer books of the Surviving

holder of shares of Axion Common Stock exchanged pursuant to the Merger who
would otherwise have been entitled to receive a fraction of a share of BMS

BMS for payment of their claim for BMS Common Stock, any cash in lieu of
fractional shares of BMS Common Stock and any dividends or distributions with
respect to BMS Common Stock.

            (g) No Liability. In the event that any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such Certificate,
the Surviving Corporation shall, in exchange for such lost, stolen or destroyed
Certificate, issue or cause to be issued the number of shares of BMS Common
Stock and pay or cause to be paid the amounts deliverable in respect thereof
pursuant to this Article II.

            (h) Withholding Rights. The Surviving Corporation shall be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Axion Common Stock such amounts as may be required to
be deducted and withheld with respect to the making of such payment under the
Code, or under any provision of state, local or foreign tax law. To the extent
that amounts are so withheld and paid over to the appropriate taxing authority,
such withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the holder of Axion Common Stock in respect of which such
deduction and withholding was made.

on a pro rata basis from the shares of BMS Common Stock to be issued and
delivered to each Former Axion Stockholder with respect to its shares of Axion
Common Stock pursuant to Section 2.02(b), calculated based on the ratio of the
number of shares of BMS Common Stock to be so issued and delivered to such

aggregate number of shares of BMS Common Stock to be so issued to all the Former
Axion Stockholders with respect to their shares of Axion Common Stock.

following the Distribution, the AHC stockholders, in connection with the

Except as set forth in Schedule 4.01(g) and except for the execution and
delivery of the Documents and consummation of the transactions contemplated

                                                                              27


December 31, 1995 to the stockholders of Axion and, accordingly, OnCare is no
longer a Subsidiary of Axion) and has made all reasonable best efforts to
preserve Axion's and its Subsidiaries' relationships with customers, suppliers,
licensors, licensees, distributors and others with whom Axion or any Subsidiary
deals. Except as set forth in Schedule 4.01(g), since December 31, 1995, to the
date of this Agreement, neither Axion nor any of its Subsidiaries has taken any
action that, if taken after the date hereof, would constitute a breach of any of
the covenants set forth in Section 5.01 or 5.02.

            (h) Benefit Plans, Employment and Labor Relations. (i) Schedule
4.01(h) contains a list (and with respect to any Benefit Plans (as defined
below) that are not in written form, a brief description) of all "employee
pension benefit plans" (as defined in Section 3(2) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) (sometimes referred to herein
as "Pension Plans"), "employee welfare benefit plans" (as defined in Section
3(1) of ERISA) and all other plans, agreements, policies or arrangements
relating to stock options, stock purchases, compensation, deferred compensation,
severance, and other employee benefits, in each case maintained or contributed
to as of the date of this Agreement by Axion or any of its Subsidiaries or any
other person or entity that, together with Axion, is treated as a single
employer under Section 414(b), (c), (m) or (o) of the Code (a "Commonly
Controlled Entity") for the benefit of any current or former employees, officers
or directors of Axion or any Commonly Controlled Entity (collectively, the
"Benefit Plans"). Axion has delivered to BMS true, complete and correct copies
of (w) each Benefit Plan (or, in the case of any unwritten Benefit Plans,
descriptions thereof), (x) the two most recent annual reports on Form 5500 filed
with the Internal Revenue Service ("IRS") with respect to each Benefit Plan (if
any such report was required), including all schedules and attachments thereto,
(y) the most recent summary plan description for each Benefit Plan for which
such summary plan description is required and (z) each trust agreement, group
annuity contract and other funding or financing arrangement relating to any
Benefit Plan. To the knowledge of Axion, each such Form 5500 and each such
summary plan description (or similar document) was and is as of the date hereof
true, complete and correct in all material respects.

            (ii) Each Benefit Plan has been administered in all material
respects in accordance with its terms. Axion

                                                                              28


and its Commonly Controlled Entities and all the Benefit Plans are in compliance
in all material respects with the applicable provisions of ERISA, the Code, all
other applicable laws and the terms of all applicable collective bargaining
agreements. All reports, returns and similar documents with respect to the
Benefit Plans required to be filed with any governmental agency or distributed
to any Benefit Plan participant have been duly and timely filed or distributed
and, to the knowledge of Axion, all reports, returns and similar documents
actually filed or distributed were true, complete and correct in all material
respects. There are no investigations by any governmental agency, termination
proceedings or other claims (except routine claims for benefits payable under
the Benefit Plans), suits or proceedings against or involving any Benefit Plan
or asserting any rights of or claims for benefits under any Benefit Plan that
could give rise to any material liability, and there are not any facts or
circumstances that could give rise to any material liability in the event of any
such investigation, claim, suit or proceeding.

            (iii) The Datair Mass-Submitter Prototype Defined Contribution Plan
and Trust and related Adoption Agreement comprising the Axion Pharmaceuticals,
Inc. 401(k) Profit Sharing Plan and Trust is the subject of a valid opinion
letter from the IRS with respect to conformance with Sections 401 and 501(a) of
the Code, and Axion has adopted all amendments and is in compliance with all
applicable requirements in order to rely on such opinion letter for purposes of
maintaining a defined contribution plan qualified under Section 401 and 501(a)
of the Code.

          (iv) All contributions to, and payments from, the Benefit Plans and
all insurance premiums that may have been required to be made in accordance with
the terms of the Benefit Plans and any applicable collective bargaining
agreement have been timely made. Neither Axion nor any Commonly Controlled
Entity sponsors, maintains or contributes to (or has ever sponsored, maintained
or contributed to) a Pension Plan subject to Title IV of ERISA or Section 412 of
the Code. None of Axion, any of its Subsidiaries, any officer of Axion or any of
its Subsidiaries or any of the Benefit Plans which are subject to ERISA,
including the Pension Plans, any trusts created thereunder or, to the knowledge
of Axion, any trustee or administrator thereof, has engaged in a "prohibited
transaction" (as such term is defined in Section 406 of ERISA or Section 4975 of
the Code) or any other breach of

fiduciary responsibility that could subject Axion, any of its Subsidiaries or
any officer of Axion or any of its Subsidiaries to the tax or penalty on
prohibited transactions imposed by such Section 4975 or to any liability under
Section 409 or Section 502(i) or (l) of ERISA.

            (v) With respect to any Benefit Plan that is an employee welfare
benefit plan, (x) no such Benefit Plan is funded through a "welfare benefits
fund", as such term is defined in Section 419(e) of the Code, (y) each such
Benefit Plan that is a "group health plan", as such term is defined in Section
5000(b)(1) of the Code, complies with the applicable requirements of Section
498OB(f) of the Code and (z) each such Benefit Plan (including any such Plan
covering retirees or other former employees) may be amended or terminated
without material liability to Axion or any of its Subsidiaries on or at any time
after the Effective Time.

            (vi) No Commonly Controlled Entity has acted in a manner that could,
or failed to act so as to, result in fines, penalties, taxes or related charges
under (A) Section 502(c), (i) or (l) of ERISA or (B) Chapter 43 of the Code.

            (vii) Neither Axion nor any Commonly Controlled Entity contributes
or is obligated to contribute (or has ever been obligated to contribute) to a
"multiemployer plan" (within the meaning of Section 4001(a)(3) of ERISA.

            (viii) Except as set forth on Schedule 4.01(h), no employee of Axion
will be entitled to any additional benefits or any acceleration of the time of
payment or vesting of any benefits under any Benefit Plan as a result of the
transactions contemplated by this Agreement or the other Documents.

            (i) Absence of Changes in Benefit Plans. Except as set forth on
Schedule 4.01(i) and except in accordance with the provisions of Article VI of
the Distribution Agreement, since December 31, 1995, there has not been any

Subsidiaries of any Benefit Plan.

Time is operating and is projected to operate on a loss basis to the extent
previously disclosed to BMS in writing and (ii) the OPUS Station Business when

complete list of all patents, trademarks (registered or unregistered),

Intellectual Property is validly held by Axion or the relevant Subsidiary (or,
in the case of any Intellectual Property that is necessary for the conduct of
the business of the Retained Company and its Subsidiaries immediately following
the Effective Time or are otherwise owned, used, filed by or licensed to the
Retained Company and its Subsidiaries on the date hereof, will be validly held
by the Retained Company or one of its Subsidiaries immediately following the
Effective Time). Axion and its Subsidiaries have the right with respect to all
Intellectual Property listed in Schedule 4.01(q)(i), and immediately following
the Effective Time the Retained Company and its Subsidiaries will have the right
with respect to all Intellectual Property listed in Schedule 4.01(q)(ii), to
use, execute, reproduce, display, perform, modify, enhance, distribute, prepare
derivative works of and sublicense, without payment to any other person, all
such Intellectual Property. The execution, delivery or performance of the
Documents or the consummation of the Contributions, the Distribution or the
Merger or the other transactions contemplated hereby or thereby will not
conflict with, alter or impair any such rights of the Retained Companies.

            Except as set forth in the Documents or in Schedule 4.01(q)(i),
neither Axion nor any of its Subsidiaries has granted any options, licenses or
agreements of any kind relating to Intellectual Property listed in Schedules
4.01(q)(i) or 4.01(q)(ii) or the marketing or distribution thereof. Neither
Axion nor any of its Subsidiaries is bound by or a party to any options,
licenses or agreements of any kind relating to the Intellectual Property of any
other person, except as set forth in the Documents or in Schedules 4.01(q)(i) or
4.01(q)(ii). All Intellectual Property listed in Schedules 4.01(q)(i) and
4.01(q)(ii) is free and clear of the claims of others and of all Liens. The
conduct of the business of Axion and its Subsidiaries as presently conducted and
the conduct of the business of the Retained Company and its Subsidiaries as
proposed to be conducted immediately following the Effective Time does not
violate, conflict with or infringe the Intellectual Property of any other person
other than any such violations, conflicts or infringements that individually or
in the aggregate, have not had, and could not reasonably be expected to have, a
Retained Company Material Adverse Effect or an Axion Material Adverse Effect.
There are no claims pending or, to the knowledge of Axion, threatened, against
Axion or any Subsidiary by any person with respect to the ownership, validity,
enforceability,

effectiveness or use of any Intellectual Property. Since January 1, 1993, Axion
and its Subsidiaries have not received any communications alleging that Axion or
any Subsidiary has violated any rights relating to Intellectual Property of any
person.

            The Intellectual Property listed in Schedule 4.01(q)(ii) has been
maintained in confidence in accordance with protection procedures customarily
used in the industries of Axion and its Subsidiaries to protect rights of like
importance. All former and current members of management and key personnel of
Axion or any of its Subsidiaries, including all former and current employees of
Axion or any of its Subsidiaries and all agents, consultants and independent
contractors retained by Axion or any of its Subsidiaries, in each case who have
contributed to or participated in the conception and development of software or
other Intellectual Property listed in Schedule 4.01(q)(ii) (collectively,
"Personnel"), have executed and delivered to Axion or such Subsidiary a
proprietary information agreement restricting such person's right to disclose
proprietary information of Axion, its Subsidiaries and their respective clients.
All former and current Personnel either (i) have been party to a "work-for-hire"
arrangement or agreement with Axion, in accordance with applicable Federal and
state law, that has accorded Axion or its Subsidiaries full, effective,
exclusive and original ownership of all tangible and intangible property thereby
arising or (ii) have executed appropriate instruments of assignment in favor of
Axion or its Subsidiary as assignee that have conveyed to Axion or its
Subsidiary full, effective and exclusive ownership of all tangible and
intangible property thereby arising. No former or current Personnel have any
valid claim against Axion or any of its Subsidiaries in connection with such
person's involvement in the conception and development of any Intellectual
Property which is necessary for the conduct of the business of the Retained
Company and its Subsidiaries immediately following the Effective Time or are
otherwise owned, used, filed by or licensed to the Retained Company and its
Subsidiaries on the date hereof, and no such claim has been asserted or, to the
knowledge of Axion, is threatened. None of the current officers and employees of
Axion or any of its Subsidiaries have any patents issued or applications pending
for any device, process, design or invention of any kind now used or needed by
Axion or any of its Subsidiaries in the furtherance of its business operations,
which patents or applications have not been

United States Patent Office.

            (r) Assets Other than Real Property Interests. Axion or one of its
Subsidiaries has good and valid title to all assets reflected on the December
31, 1995 audited consolidated balance sheet included in the Axion Financial
Statements (the "December 31, 1995 Axion Balance Sheet") or thereafter acquired
("Axion Personal Property"), except (x) those sold or otherwise disposed of for
fair value since December 31, 1995 in the ordinary course of business consistent
with past practice and not in violation of this Agreement and (y) those
transferred to OnCare in connection with the distribution of the capital stock
of OnCare on December 31, 1995 to the Axion stockholders as reflected in Note 2
("Investment in Oncare Inc.") to the Audited Axion Financial Statements, in each
case free and clear of all mortgages, Liens, security interests or encumbrances
of any kind except (i) such as are set forth in Schedule 4.01(r)(i), (ii)
mechanics', carriers', workmen's, repairmen's or other like liens arising or
incurred in the ordinary course of business, liens arising under original
purchase price conditional sales contracts and equipment leases with third
parties entered into in the ordinary course of business and liens for Taxes and
other governmental charges which are not due and payable or which may thereafter
be paid without penalty, (iii) mortgages, Liens, security interests and
encumbrances which secure debt that is reflected as a liability on the December
31, 1995 Axion Balance Sheet and the existence of which is indicated in the
notes thereto and (iv) other imperfections of title or encumbrances, if any,
which do not, individually or in the aggregate, materially impair the continued
use and operation of the assets to which they relate in the business of Axion
and its Subsidiaries taken as a whole as presently conducted (the mortgages,
Liens, security interests, encumbrances and imperfections of title described in
clauses (ii), (iii) and (iv) above are hereinafter referred to collectively as
"Permitted Liens"). Schedule 4.01(r)(ii) sets forth a true and complete list of
all Axion Personal Property which is necessary for the conduct of the business
of the Retained Company and its Subsidiaries immediately following the Effective
Time or are otherwise used or maintained by or for the benefit of the Retained
Company and its Subsidiaries on the date hereof. Title to all Axion Personal
Property is validly held by Axion or the relevant Subsidiary (or, in the case of

the

Retained Company and its Subsidiaries immediately following the Effective Time
or are otherwise used or maintained by or for the benefit of the Retained
Company and its Subsidiaries on the date hereof, will be validly held by the
Retained Company or one of its Subsidiaries). Immediately following the
Effective Time the Retained Company and its Subsidiaries will have the right
with respect to Axion Personal Property listed in Schedule 4.01(r)(ii) to the
continued use and operation of such Axion Personal Property. The execution,
delivery or performance of the Documents or the consummation of the
Contributions, the Distribution or the Merger or the other transactions
contemplated hereby or thereby will not conflict with, alter or impair any such
rights of the Retained Companies.

            All material Axion Personal Property has been maintained in all
material respects in accordance with the past practice of Axion and its
Subsidiaries and generally accepted industry practice. Each item of material
Axion Personal Property is in all material respects in good operating condition
and repair, ordinary wear and tear excepted. All leased Axion Personal Property
is in all material respects in the condition required of such property by the
terms of the lease applicable thereto during the term of the lease and upon the
expiration thereof.

            This Section 4.01(r) does not relate to real property or interests
in real property, such items being the subject of Section 4.01(s).

            (s) Title to Real Property. Schedule 4.01(s)(i) sets forth a
complete list of all real property and interests in real property owned in fee
by Axion and its Subsidiaries (individually, an "Owned Property") and identifies
any material reciprocal easement or operating agreements relating thereto.

interests in real property leased by Axion and its Subsidiaries (individually, a
"Leased Property", an Owned Property or Leased Property being sometimes referred

Properties"), and identifies any material base leases and reciprocal easement or
operating agreements relating thereto. Schedule 4.01(s)(ii) sets forth a true
and complete list of all Axion Property which is necessary for the conduct of
the business of the Retained Company and its Subsidiaries immediately following

Company and its Subsidiaries on the date hereof. Either Axion or its Subsidiary
has (or in the case of any Axion Property that is necessary for the conduct of
the business of the Retained Company and its Subsidiaries immediately following
the Effective Time or are otherwise used or maintained by or for the benefit of
the Retained Company and its Subsidiaries on the date hereof, the Retained
Company and its Subsidiaries will have) (i) good and insurable fee title to all
Owned Property and (ii) good and valid title to the leasehold estates in all
Leased Property, in each case free and clear of all mortgages, Liens, security
interests, encumbrances, leases, assignments, subleases, easements, covenants,
rights-of-way and other similar restrictions of any nature whatsoever, except

interests, encumbrances, easements, covenants, rights-of-way and other similar
restrictions that have been placed by any developer, landlord or other third
party on property over which Axion or its Subsidiary has easement rights or on
any Leased Property and subordination or similar agreements relating thereto,
and (III) unrecorded easements, covenants, rights-of-way and other similar
restrictions, none of which items set forth in clauses (I), (II) and (III),
individually or in the aggregate, materially impair the continued use and
operation of the property to which they relate in the business of the Retained
Company and its Subsidiaries taken as a whole or AHC and its Subsidiaries taken
as a whole as presently conducted. The current use by Axion and its Subsidiaries
does not and the proposed use by the Retained Company and its Subsidiaries of
the plants, offices and other facilities located on Axion Property does not
violate any local zoning or similar land use or government regulations in any
material respect. Axion and its Subsidiaries have with respect to the Axion
Property listed in Schedule 4.01(s)(i), and immediately following the Effective
Time the Retained Company and its Subsidiaries will have the right with respect
to the Axion Property listed in Schedule 4.01(s)(ii), to use such Axion
Property. The execution, delivery or performance of the Documents or the

Subsidiaries or any of their respective properties, assets, operations or
businesses and which (i) relate to or involve more than $10,000, (ii) seek any
injunctive or other equitable relief or (iii) relate to the Contributions, the

could reasonably be expected to have, if so determined, individually or in the
aggregate, a Retained Company Material Adverse Effect or an AHC Material Adverse
Effect. Axion is not aware of any unasserted claims (or of any facts which would
support any such claims) of the type that would be required to be disclosed in
Schedule 4.01(t) if counsel for the claimant had contacted Axion or any of its
Subsidiaries. Neither Axion nor any of its Subsidiaries is a party or subject to
or in default under any judgment, order, injunction or decree of any
Governmental Entity or arbitration tribunal applicable to it or any of its
respective properties, assets, operations or business. There is no lawsuit or
claim by Axion or any of its Subsidiaries pending, or which Axion or any of its
Subsidiaries intends to initiate, against any other person. Except as set forth

or in the aggregate, a Retained Company Material Adverse Effect or an AHC
Material Adverse Effect; (vi) there are no pending, or, to the knowledge of
Axion, threatened, charges against Axion, any of its Subsidiaries or any current

of its Subsidiaries has received notice since January 1, 1993, of the intent of
any Governmental Entity responsible for the enforcement of labor or employment
laws to conduct an investigation of or affecting Axion or any of its
Subsidiaries and, to the knowledge of Axion, no such investigation is in

      which has an aggregate future liability to any person (including Axion or
      any of its Subsidiaries) in excess of $25,000 or is not terminable by
      Axion or such Subsidiary by notice of not more than 60 days for a cost of
      less than $25,000.

All agreements, Contracts, leases, licenses, commitments or instruments of Axion
or any of its Subsidiaries listed in the Schedules hereto (collectively, the
"Scheduled Contracts") are valid, binding and in full force and effect (except
to the extent that any such Scheduled Contracts automatically terminate in
accordance with their terms after the date hereof) and are enforceable by Axion
or its relevant Subsidiary in accordance with their respective terms (except as
such enforceability may be limited by (i) bankruptcy, insolvency, moratorium,
reorganization and other similar laws affecting creditor' rights generally and
(ii) the general principles of equity, regardless of whether asserted in a
proceeding in equity or at law). Neither Axion nor any of its Subsidiaries has
received written notice of, and Axion does not otherwise have actual knowledge
of, any pending or threatened proceedings under bankruptcy, insolvency,
moratorium, reorganization or other similar laws affecting creditor's rights
generally by or with respect to any party (other than Axion or its Subsidiaries)
to any Scheduled Contract or any pending or threatened claims challenging the
enforceability of any Scheduled Contract under the general principles of equity,
regardless of whether asserted in a proceeding in equity or at law. Axion and
its Subsidiaries have performed all material obligations required to be
performed by them to date under the Scheduled Contracts and they are not (with
or without the lapse of time or the giving of notice, or both) in breach or
default in any material respect thereunder and, to the knowledge of Axion, no
other party to any of the Scheduled Contracts is (with or without the lapse of
time or the giving of notice, or both) in breach or default in any material
respect thereunder. Complete and correct copies of all Scheduled Contracts,
together with all amendments or modifications thereto (including any waivers
related thereto), have been provided to BMS or its counsel.

            (w) Insurance. The insurance policies (other than any Benefit Plans)
maintained with respect to Axion and its Subsidiaries and their respective
assets and properties are listed in Schedule 4.01(w). All such policies are in
full force and effect, all premiums due and payable thereon have been paid
(other than retroactive or retrospective

                                                                              48


premium adjustments that are not yet, but may be, required to be paid with
respect to any period ending prior to the Closing Date under comprehensive
general liability and workmen's compensation insurance policies), and no notice
of cancelation or termination has been received with respect to any such policy
which has not been replaced on substantially similar terms on or prior to the
date of such cancelation. The activities and operations of Axion and its
Subsidiaries have been conducted in a manner so as to conform in all material
respects to all applicable provisions of such insurance policies. Axion and its
Subsidiaries maintain policies of fire and casualty, liability and other forms
of insurance in such amounts, with such deductibles and against such risks and
losses as are, in Axion's judgment, reasonable for the business and assets of
Axion and its Subsidiaries taken as a whole. Except as set forth in Schedule
4.01(w), none of the insurance policies will be canceled or terminated (or give
the insurer the right to cancel or terminate the insurance policies) as a result
of the execution, delivery or performance of the Documents or the consummation
of the Contributions, the Distribution or the Merger or the other transactions
contemplated hereby or thereby. Schedule 4.01(w) sets forth a true a complete
list of all insurance policies which are necessary for the conduct of the
business of the Retained Company and its Subsidiaries immediately following the
Effective Time or are otherwise maintained by or for the benefit of the Retained
Company and its Subsidiaries on the date hereof. Except as set forth in Schedule
4.01(w), all such insurance policies are validly owned by Axion or the relevant
Subsidiary (or in the case of any insurance policies that are necessary for the
conduct of the business of the Retained Company and its Subsidiaries immediately
following the Effective Time or are otherwise maintained by or for the benefit
of the Retained Company and its Subsidiaries on the date hereof, will be held or
owned by the Retained Company or one of its Subsidiaries) and immediately
following the Effective Time Axion and its Subsidiaries will have the right to
hold or own all insurance policies listed in Schedule 4.01(w), or in the case of
any insurance policies that are necessary for the conduct of the business of the
Retained Company and its Subsidiaries immediately following the Effective Time
or are otherwise maintained by or for the benefit of the Retained Company and
its Subsidiaries on the date hereof, the Retained Company and its Subsidiaries
will immediately following the Effective Time have the right to hold or own all
such insurance policies.

            (x) Customer Accounts Receivable; Inventories. (i) All customer
accounts receivable of the Retained Company and its Subsidiaries, whether
reflected on the December 31, 1995 unaudited consolidated balance sheet of Axion
included in the Retained Company Financial Statements (the "December 31, 1995
Retained Company Balance Sheet") or subsequently created, have arisen from bona
fide transactions in the ordinary course of business. All such customer accounts
receivable are good and collectible at the aggregate recorded amounts thereof,
net of any applicable reserves for doubtful accounts reflected on the December
31, 1995 Retained Company Balance Sheet. The Retained Company and its
Subsidiaries have good and marketable title to their respective accounts
receivable, free and clear of all Liens, except as set forth in Schedule
4.01(x). Since December 31, 1995, there have not been any write-offs as
uncollectible of any notes or accounts receivable related to the Retained
Business, except for write-offs in the ordinary course of business and
consistent with past practice which have not had, and could not reasonably be
expected to have, either individually or in the aggregate, a Retained Company
Material Adverse Effect.

            (ii) The inventories of the Retained Company and its Subsidiaries,
whether reflected on the December 31, 1995 Retained Company Balance Sheet or
subsequently acquired, are generally of a quality and quantity usable and
salable at customary gross margins and with customary markdowns consistent in
all material respects with past practice in the ordinary course of business. The
inventories of the Retained Company and its Subsidiaries are reflected on the
December 31, 1995 Retained Company Balance Sheet and in their respective books
and records in accordance with generally accepted accounting principles applied
on a basis consistent with past practice. Since December 31, 1995, there have
not been any write-downs of the value of, or establishment of any reserves
against, any inventory of the Retained Company and its Subsidiaries, except for
write-downs and reserves in the ordinary course of business and consistent with
past practice which have not had, and could not reasonably be expected to have,
either individually or in the aggregate, a Retained Company Material Adverse
Effect.

            (y) Accounts; Safe Deposit Boxes; Powers of Attorney; Officers and
Directors. Schedules 4.01(y)(i), (y)(ii) and (y)(iii) set forth (i) a true and
correct list of all bank and savings accounts, certificates of deposit

                                                                              50


and safe deposit boxes of Axion and its Subsidiaries and those persons
authorized to sign thereon, (ii) true and correct copies of all corporate
borrowing, depository and transfer resolutions and those persons entitled to act
thereunder, (iii) a true and correct list of all powers of attorney granted by
Axion and its Subsidiaries and those persons authorized to act thereunder and
(iv) a true and correct list of all officers and directors of Axion and its
Subsidiaries.

            (z) Transactions with Affiliates. Except as set forth in Schedule
4.01(z), none of the Scheduled Contracts between the Retained Company or any of
its Subsidiaries, on the one hand, and AHC or any of its Subsidiaries or
affiliates (including OnCare and its Subsidiaries), on the other hand, will
continue in effect subsequent to the Closing. Neither Axion nor any of its
Subsidiaries have directly or indirectly entered into or permitted to exist any
transaction with any affiliate on terms that are less favorable to such person
than those that could be obtained in an arm's-length transaction with a third
party. Neither AHC or any of its Subsidiaries nor OnCare or any of its
Subsidiaries nor, to the knowledge of Axion, any of their respective senior
officers, (a) has any direct or indirect ownership interest in any person in
which the Retained Company or any of its Subsidiaries has any direct or indirect
ownership interest in any person or (b) has, individually or in the aggregate,
any direct or indirect controlling ownership interest in any person with which
the Retained Company or any of its Subsidiaries competes or has a business
relationship (other than persons engaged in the pharmaceutical manufacturing
industry).

            (aa) Effect of Transaction. As of the date of this Agreement no
creditor, employee, client, customer or other person having a material business
relationship with the Retained Company or any of its Subsidiaries has informed
Axion or any of its Subsidiaries (orally or in writing) that such person intends
to change such relationship because of the Contributions, the Distribution, the
Merger or any of the other transactions contemplated by the Documents, which
change, individually or in the aggregate with other such changes, have had, or
could reasonably be expected to have, a Retained Company Material Adverse
Effect.

            (bb) Disclosure. (i) No representation or warranty of Axion or any
of its Subsidiaries contained in any Document, (ii) no statement by Axion or any
of its

                                                                              51


Subsidiaries to BMS or any of its representatives contained in any document,
certificate or schedule furnished or to be furnished by or on behalf of Axion or
any of its Subsidiaries to BMS or any of its representatives pursuant to any
Document, and (iii) to the knowledge of Axion, no other statement by Axion or
any of its Subsidiaries and no statement by any unaffiliated third party
contained in any such document, certificate or schedule furnished or to be
furnished to BMS or any of its representatives pursuant to any Document, in each
case, contains or will contain any untrue statement of a material fact, or omits
or will omit to state any material fact necessary, in light of the circumstances
under which it was or will be made, in order to make the statements herein or
therein not misleading or necessary in order to fully and fairly provide the
information required to be provided by Axion or its Subsidiaries in any Document
or in any such document, certificate or schedule. The financial projections and
valuations relating to the Retained Company and its Subsidiaries and to AHC and
its Subsidiaries delivered to BMS by Axion or its representatives (including
Alex. Brown and Ernst & Young LLP) were prepared on the basis of assumptions
Axion reasonably believed in good faith at the time of preparation to be
reasonable, and Axion has no knowledge of any fact or information that would
lead it to believe that such assumptions are incorrect or misleading in any
material respect.

            (cc) Suppliers. Neither Axion nor any of its Subsidiaries has
entered into or made any Contract which has an aggregate future liability to any
person (other than Axion or any of its Subsidiaries) in excess of $25,000 for
the purchase of merchandise other than in the ordinary course of business
consistent with past practice and other than any Contract that terminated on or
prior to December 31, 1995 (and in respect of which neither Axion nor any of its
Subsidiaries has any further liability). Except for the suppliers named in
Schedule 4.01(cc), neither Axion nor any of its Subsidiaries has any supplier
(other than Axion or its Subsidiaries) from whom it purchased more than 5% of
the merchandise which it purchased during its most recent full fiscal year.
Since December 31, 1995, there has not been (i) any material adverse change in
the business relationship of Axion or its Subsidiaries with any supplier of
merchandise named in Schedule 4.01(cc) or (ii) any change in any material term
(including credit terms) of the supply agreements or related arrangements with
any such supplier.

            (dd) Customers. Neither Axion nor any of its Subsidiaries has
entered into or made any Contract for the sale of merchandise which,
individually or in the aggregate, would be material to the business of the
Retained Company and its Subsidiaries other than in the ordinary course of
business consistent with past practice and other than Contracts that terminated
on or prior to December 31, 1995 (and in respect of which neither Axion nor any
of its Subsidiaries has any further liability). Except for the customers named
in Schedule 4.01(dd), neither the Retained Company nor any of its Subsidiaries
has any customer to whom it made more than 5% of its sales during its most
recent full fiscal year. Since December 31, 1995, there has not been (i) any
material adverse change in the business relationship of Axion or any of its
Subsidiaries with any customer named in Schedule 4.01(dd) or (ii) any change in
any material term (including credit terms) of the sales agreements or related
agreements with any such customer. Since January 1, 1993, the Retained Company
and its Subsidiaries have received no customer complaints concerning their
products and services, nor have they had any of their products returned by a
purchaser thereof, other than complaints and returns in the ordinary course of
business which have not had, and could not reasonably be expected to have,
individually or in the aggregate, a Retained Company Material Adverse Effect.

            (ee) Accuracy of Representations and Warranties. No representation
made by Axion or any of its Subsidiaries in any Document or any of the schedules
hereto or thereto is false or misleading in any material respect or contains any
material misstatement of fact.

            SECTION 4.02. Representations and Warranties of BMS. BMS represents
and warrants to Axion as follows:

            (a) Organization, Standing and Corporate Power. Each of BMS and BMS
Sub is a corporation duly organized, validly existing and in good standing under
the laws of the State of Delaware and has the requisite corporate power and
authority to carry on its business as now being conducted. Each of BMS and BMS
Sub is duly qualified or licensed to do business and is in good standing in each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification or licensing necessary, other than in
such jurisdictions where the failure to be so qualified or licensed
(individually or in the aggregate) would not have a material adverse effect on

                                                                              53


the business, operations, assets, liabilities (including contingent
liabilities), results of operations, financial condition or prospects of BMS and
its Subsidiaries taken as a whole (a "BMS Material Adverse Effect"). BMS has
delivered to Axion complete and correct copies of the Certificate of
Incorporation and By-laws of each of BMS and BMS Sub, in each case as amended to
the date hereof.

            (b) Validly Issued. All shares of BMS Common Stock which may be
issued pursuant to this Agreement will be, when issued, duly authorized, validly
issued, fully paid and nonassessable, not subject to preemptive rights and free
of any liens or encumbrances other than any liens or encumbrances created by or
imposed upon the holders thereof.

            (c) Authority; Noncontravention. (i) Each of BMS and BMS Sub has all
requisite corporate power and authority to execute and deliver each Document to
which it is or will be a party and to consummate the transactions contemplated
hereby and thereby. The execution, delivery and performance of each Document to
which it is or will be a party and the consummation of the Merger and the other
transactions contemplated hereby and thereby in accordance with their respective
terms in each case by BMS or BMS Sub, as the case may be, have been duly
authorized by all necessary corporate action on the part of BMS and BMS Sub, and
no other corporate proceedings are required on the part of BMS or BMS Sub to
consummate the transactions so contemplated. Each Document to which BMS or BMS
Sub is or will be a party has been, or will be, duly executed and delivered by
BMS or BMS Sub, as applicable, and constitutes or, upon such execution and
delivery will constitute, a valid and binding obligation of such party,
enforceable against such party, in accordance with its terms.

            (ii) None of the execution, delivery or performance by BMS or BMS
Sub of any Document to which BMS or BMS Sub is or will be a party, the
consummation of the transactions contemplated hereby and thereby or the
compliance by BMS or BMS Sub with the terms of each Document to which BMS or BMS
Sub is or will be a party will conflict with, or result in any violation or
breach of, or default (with or without notice or lapse of time, or both) under,
or give rise to any right of termination, amendment, cancelation or acceleration
of any material obligation or to loss of a material benefit under, or result in
the creation of any Lien upon any of the properties or assets of BMS or BMS Sub
(i) under the Certificate of Incorporation or

By-laws of BMS or BMS Sub or the comparable charter or organizational documents
of any other Subsidiary of BMS, (ii) any loan or credit agreement, note, bond,
mortgage, indenture, lease or other agreement, instrument, permit, concession,
franchise or license applicable to BMS or any Subsidiary of BMS or their
respective properties or assets or (iii) subject to the governmental filings and
other matters referred to in the following sentence, any judgment, order,

                                                                              62


such action might otherwise be permitted pursuant to this Article V, Axion shall
not, nor shall it permit any of its Subsidiaries to, take any action that would
or is reasonably likely to result in (i) any of the conditions to the Merger set
forth in Article VII not being satisfied, (ii) any of the representations and
warranties of Axion set forth in this Agreement that are qualified as to
materiality becoming untrue or (iii) any of such representations and warranties
that are not so qualified becoming untrue in any material respect, or that would
materially impair the ability of Axion to consummate the Contributions or the
Distribution in accordance with the terms of the Distribution Agreement or the
Merger in accordance with the terms hereof or would materially delay such
consummation or that would, to the knowledge of Axion, disqualify the
Distribution as a tax-free spinoff within the meaning of Section 355 of the Code
or disqualify the Merger as a tax-free reorganization under Section 368(1)(B) of
the Code.

            (b) Intercompany Transactions. Axion shall (i) not engage in or
allow transfers of assets or liabilities or engage or enter into other

sole discretion.

            (c) Advice of Changes; Filings. Axion shall promptly advise BMS
orally and in writing of any change or development or combination of changes or
developments that would cause the representation in Section 4.01(g) to be

connection with the Documents and the transactions contemplated hereby and
thereby.

Closing, Axion shall give prompt notice to BMS of (A) the occurrence, or failure
to occur, of any event which occurrence or failure would be likely to cause any
representation or warranty contained in this Agreement or any other Document to
be untrue or inaccurate in any material respect and (B) any material failure of
Axion or any of its Subsidiaries or affiliates, or of any of its stockholders or
holders of Axion Options, to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by it under this Agreement or any
other Document; provided, however, that such disclosure shall not be deemed to
cure any breach of a representation, warranty, covenant or agreement or to
satisfy any condition. Axion shall promptly notify BMS of any default, the
threat or commencement of any action, or any development that occurs before the
Closing that could in any way materially affect the Retained Business, the
Retained Company and its Subsidiaries or AHC and its Subsidiaries. Axion shall
have the continuing obligation until the Closing to supplement or amend the
Schedules hereto on a monthly basis with the final supplement or amendment to

to consummate the Merger and the other transactions contemplated hereby not to
be fulfilled.

            (g) Exclusivity. (i) Axion shall, and shall direct and use its best
efforts to cause its officers, directors, employees, representatives and agents
to, immediately cease any discussions or negotiations with any parties that may
be ongoing with respect to a Acquisition Proposal (as hereinafter defined).
Axion shall not, nor shall it permit any of its Subsidiaries to, nor shall it
authorize or permit any of its officers, directors or employees or any
investment banker, financial advisor, attorney, accountant or other
representative retained by it or any of its Subsidiaries to, directly or

furnishing information), or take any other action designed or reasonably likely
to facilitate, any inquiries or the making of any proposal which constitutes, or
may reasonably be expected to lead to, any Acquisition Proposal or (B)
participate in any discussions or negotiations regarding any Acquisition
Proposal. Without limiting the foregoing, it is understood that any violation of
the restrictions set forth in the preceding sentence by any director or
executive officer of Axion or any of its Subsidiaries, whether or not such

otherwise, shall be deemed to be a breach of this Section 5.02(g) by Axion. For

or offer from any person with respect to a merger, acquisition, consolidation or
similar transaction involving, or any purchase of all or any significant portion
of the assets or any equity securities of, the Retained Business, other than the

consummation of which could reasonably be expected to impede, interfere with,
prevent or materially delay the Merger or which would reasonably be expected to
dilute materially the benefits to BMS of the transactions contemplated by this
Agreement and the other Documents.

          (ii) Neither the Board of Directors of Axion nor any committee thereof
shall (A) withdraw or modify, or propose publicly to withdraw or modify, in a
manner adverse to BMS, the approval or recommendation by such Board of Directors
or such committee of the Merger or this Agreement, (B) approve or recommend, or
propose publicly to approve or recommend, any Acquisition Proposal or (C) cause
Axion to

enter into any letter of intent, agreement in principle, acquisition agreement
or other similar agreement related to any Acquisition Proposal.

            (iii) In addition to the obligations of Axion set forth in
paragraphs (i) and (ii) of this Section 5.02(g), Axion shall immediately advise
BMS orally and in writing of any request for information or of any Acquisition
Proposal, the material terms and conditions of such request or Acquisition
Proposal and the identity of the person making such request or Acquisition
Proposal. Axion will keep BMS fully informed of the status and details
(including amendments or proposed amendments) of any such request or Acquisition
Proposal.

            SECTION 5.03. Covenants of BMS. During the period from the date of
this Agreement and continuing to the Effective Time, BMS agrees as to itself and
its subsidiaries that, except to the extent that Axion shall otherwise consent
in writing with such consent to be within Axion's sole discretion:

            (a) Actions Affecting the Merger. Notwithstanding the fact that such
action might otherwise be permitted pursuant to this Article V, BMS shall not,
and shall not permit any of its Subsidiaries to, take any action that would or
could reasonably be likely to result in (i) any of the conditions to the Merger
set forth in Article VII not being satisfied, (ii) any of the representations
and warranties of BMS set forth in this Agreement that are qualified as to
materiality becoming untrue, or (iii) any of such representations and warranties
that are not so qualified becoming untrue in any material respect or materially
impairing the ability of BMS to consummate the Merger in accordance with the
terms hereof.

conditions hereof, Axion shall, and shall cause its Subsidiaries to, promptly
use its reasonable best efforts to obtain any consent, authorization, order or
approval of, or any exemption by, and to satisfy any condition or requirement
imposed by, any Governmental Entity or other public or private third party,
required to be obtained, made or satisfied by Axion or any of its Subsidiaries
in connection with the Contributions, the Distribution or the Merger or the
taking of any action contemplated thereby or by this Agreement or the other
Documents. Axion agrees that it shall use its reasonable best efforts to take,
and to cause its Subsidiaries to take, such actions as are necessary to assure
material compliance by the Retained Company and its Subsidiaries with all
applicable legal and regulatory requirements which may be imposed with respect

            (d) Nothing herein shall obligate any party to take any action
pursuant to the foregoing if the taking of such action or such compliance or the
obtaining of such consent, authorization, order, approval or exemption is
likely, in such party's reasonable opinion, (i) to be materially burdensome to
such party and its Subsidiaries taken as a whole or to impact in a materially
adverse manner the economic or business benefits of the transactions
contemplated by this Agreement or the other Documents so as to render
inadvisable the consummation of the Contributions, the Distribution or the
Merger or (ii) to result in the imposition of a condition or restriction on such
party or on the Surviving Corporation of the type referred to in Section
7.01(e). Nothing herein shall obligate BMS to take any action pursuant to the
foregoing if the taking of such action or such compliance or the obtaining of

reasonable opinion, to require BMS to agree to any prohibition, limitation or
other requirement of the type set forth in clauses (ii), (iii) or (iv) of

thereby, including all fees and expenses of accountants, legal counsel,
investment bankers and other advisors shall be paid by the party incurring such
fees or expenses, whether or not the Merger is consummated, except that expenses
incurred in connection with printing and mailing the Proxy Statement and the
Form S-4 shall be shared equally by BMS and Axion. Expenses incurred in
connection with the Required AHC Documents shall be paid by Axion.

such stockholders. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties.

                                   ARTICLE IX

Axion other than AHC or OPUS Sub after giving effect to the transactions
described in Sections 3.1(a)(i) and 3.2(a) as a result of the allocation of

Partnership or OPUS after giving effect to the transactions described in

deliver, such instruments of assumption to the extent necessary to evidence such
assumption.

            3.5 Nonassignable Contracts. (a) Anything contained herein to the
contrary notwithstanding, this Agreement shall not constitute an agreement to
assign any Contract or other commitment or asset if an assignment or attempted
assignment of the same without the consent of the other party or parties thereto
would constitute a breach thereof or in any way impair the rights of AHC and its
Subsidiaries or the Retained Company and its Subsidiaries thereunder.

            (b) If any consent necessary to convey any Acquired Asset is not
obtained or if an attempted assignment would be ineffective or would impair any
party's rights under any such Contract or other Asset so that AHC or OPUS Sub
would not receive all such rights, then (x) Axion shall use its reasonable best
efforts (it being understood that such efforts shall not include any requirement
of Axion or its Subsidiaries or the Retained Company or its Subsidiaries to
expend money or offer or grant any financial accommodation) to provide or cause
to be provided to AHC or OPUS Sub, as applicable, to the extent permitted by
law, the benefits of any such Contract or other Asset, and Axion shall promptly
pay or cause to be paid to AHC or OPUS Sub, as applicable, when received all
moneys received by Axion or its Subsidiaries or the Retained Company or its
Subsidiaries with respect to any such Contract or other Asset and (y) in

discharge on behalf of Axion and the Retained Company or its Subsidiaries all
Axion and its Subsidiaries' (and the Retained Company and its Subsidiaries')
debts, liabilities, obligations and commitments thereunder in a timely manner
and in accordance with the terms thereof. In addition, Axion shall take such
other actions (at the expense of AHC or OPUS Sub, as designated by AHC) as may
reasonably be requested by AHC in order to place AHC and OPUS Sub, insofar as
reasonably possible, in the same position as if such Contract or other Asset had
been transferred as contemplated hereby and so all the benefits and burdens
relating thereto, including possession, use, risk of loss, potential for gain
and dominion, control and command are to inure to AHC or OPUS Sub, as
applicable. If and when such consents and approvals are obtained, the transfer
of the applicable asset shall be effected in accordance with the terms of this
Agreement.

Asset so that Axion or its Subsidiaries would not receive all such rights, then

discharge on behalf of AHC and its Subsidiaries all AHC and its Subsidiaries'
debts, liabilities, obligations and commitments thereunder in a timely manner
and in accordance with the terms thereof. In addition, AHC shall take such other
actions (at AHC's expense) as may reasonably be requested by Axion or BMS in
order to place Axion and its Subsidiaries, insofar as reasonably possible, in
the same position as if such Contract or other Asset had been transferred as
contemplated hereby and so all the benefits and burdens relating thereto,
including possession, use, risk of loss, potential for gain and dominion,
control and command are to inure to Axion and its Subsidiaries. If and when such
consents and approvals are obtained, the transfer of the applicable asset shall
be effected in accordance with the terms of this Agreement.

            3.6 Cooperation. The parties shall cooperate with each other in all
reasonable respects to ensure the transfer to AHC or to its Subsidiaries of the
Acquired Businesses, including the Acquired Assets and the Assumed Liabilities
and the retention by the Retained Company and its Subsidiaries of the Retained
Business, including the Retained Assets and the Retained Liabilities. Consistent
with the terms and conditions hereof, each party hereto shall execute and
deliver such instruments and take such other actions as the other parties may
reasonably require in order to carry out the provisions hereof and to consummate
the transactions contemplated hereby.

                                   ARTICLE IV

                                THE DISTRIBUTION

            4.1 Recapitalization of AHC. Effective immediately following the
Contributions and immediately prior to the Effective Time, each issued and
outstanding share of AHC Common Stock shall be converted into that number of
shares of AHC Preferred Stock as shall be equal to the quotient of (a)(i) the
number of shares of Axion Common Stock outstanding immediately prior to the Time
of Distribution (including any shares of Axion Common Stock issued in connection
with the exercise of Axion Options in connection with the consummation of the
Merger) plus (ii) the number of shares of Axion Common Stock to be issued in
connection with the conversion of Axion Preferred Stock in connection with the
consummation of the Merger divided by (b) the number of shares of AHC Common
Stock outstanding immediately prior to the Time of Distribution.

            4.2 Mechanics of Distribution. Axion shall declare and pay a
dividend of all the outstanding AHC Preferred Stock to the holders of Axion
Common Stock and the holders of Axion Preferred Stock followed by the
distribution of certificates representing (a) one share of AHC Preferred Stock
for each share of Axion Common Stock held by each holder of record of Axion
Common Stock, in the case of holders of Axion Common Stock, and (b) one share of
AHC Preferred Stock for each share of Axion Common Stock into which each share
of Axion Preferred Stock held by each holder of record of Axion Preferred Stock
is then convertible in accordance with the Certificate of Incorporation of
Axion, in the case of holders of Axion Preferred Stock, in each case at the Time
of Distribution.

            4.3 Timing of Distribution. Immediately following the Contributions
and immediately prior to the Effective Time, subject to the satisfaction or
waiver of the conditions set forth in Article VII, the Board of Directors of
Axion shall formally declare the Distribution and Axion shall effect the
Distribution by delivery of certificates for AHC Preferred Stock to the Transfer
Agent for delivery to the holders of Axion Common Stock and the holders of Axion
Preferred Stock entitled thereto. The Distribution shall be deemed to be
effective upon notification by Axion to the Transfer Agent that the Distribution
has been declared and that the Transfer Agent is authorized to proceed with the
distribution of AHC Preferred Stock, which

                                                                              18


notification Axion agrees to deliver promptly following such declaration.

                                    ARTICLE V

                                OTHER AGREEMENTS

            5.1 Insurance. (a) Except as provided in Article VI, all current
policies of liability, fire, extended coverage, fidelity, fiduciary, workers'
compensation and other forms of insurance in force as of the Time of
Distribution covering Axion and its directors and officers immediately prior to
the Time of Distribution shall be treated as Retained Assets and not as Acquired
Assets under this Agreement. All coverage under such policies with respect to
AHC and its Subsidiaries shall terminate as of the Effective Time.

            (b) Axion agrees that following the Effective Time, AHC and OPUS Sub
each shall retain the rights of an insured party under all current and former
policies of Axion and its Subsidiaries in effect at or immediately prior to the
Time of Contribution ("Axion Policy") with respect to any injury, loss,
liability, damage or expense incurred or claimed to have been incurred prior to
the Time of Distribution by any party that is an Assumed Liability to the extent
that such injury, loss, liability, damage or expense may arise out of insured or
insurable occurrences or events under one or more of such Axion Policies. Axion
shall direct the insurance carriers to pay Insurance Proceeds with respect to
such claims, costs and expenses under such policies directly to AHC or OPUS Sub,
as applicable, with respect to those liabilities that, individually or in the
aggregate, are covered within the terms and conditions of any of such policies,
whether or not subject to deductibles, co-insurance, uncollectibility or
retrospectively rated premium adjustments, but only to the extent that such
liabilities are within applicable policy limits, including aggregates.
"Insurance Proceeds" means those funds (i) received by the insured from the
insurance carrier or (ii) paid by an insurance carrier on behalf of the insured,
in either case net of any applicable premium adjustment, retrospectively rated
premium, deductible, retention, cost or reserve paid or held by or for the
benefit of the insured. Nothing set forth in this Section 5.1(b) shall be deemed
or interpreted to limit or restrict in any manner the rights of any Retained
Company as

                                                                              19


an insured party under any Axion Policy to make any claim under any Axion Policy
with respect to any Retained Liability and to receive Insurance Proceeds with
respect thereto to the extent that such liabilities are within applicable
limits, including aggregates.

            5.2 Settlement of Intercompany Balances. Except for the Specified
Intercompany Amounts (as defined in Section 5.2(b)), each of (i) the Retained
Company and its Subsidiaries, and (ii) AHC and its Subsidiaries shall submit to
the other not later than five business days prior to Closing a true and complete
schedule (with a copy to BMS) of all (i) unpaid intercompany receivables that
would, if not satisfied immediately subsequent to the Contributions constitute
intercompany receivables between the Retained Company and its Subsidiaries, on
the one hand, and AHC and its Subsidiaries, on the other hand (the "Unpaid
Intercompany Receivables"), and (ii) unpaid intercompany payables that would, if
not satisfied immediately subsequent to the Contributions constitute
intercompany payables between the Retained Company and its Subsidiaries, on the
one hand, and AHC and its Subsidiaries, on the other hand (the "Unpaid
Intercompany Payables"). Subject to the provisions of Section 2.2, all Unpaid
Intercompany Receivables and all Unpaid Intercompany Payables set forth on such
schedules outstanding immediately prior to the Time of Distribution shall be
satisfied immediately prior to the Time of Distribution; provided, however, that
in the event any such Unpaid Intercompany Receivables or such Unpaid
Intercompany Payables cannot be determined immediately prior to the Time of
Distribution (a) each of BMS and Axion shall deliver, within 30 days after
Closing, to the other party a notice in sufficient detail to enable the other
party to confirm the nature and amount of such party's Unpaid Intercompany
Receivables and Unpaid Intercompany Payables together with a reasonably detailed
calculation of the amounts thereof and (b) not more than 10 days subsequent to
receipt of such notice, all Unpaid Intercompany Receivables and Unpaid
Intercompany Payables listed in such notice shall be satisfied as follows: (i)
the Unpaid Intercompany Receivables and the Unpaid Intercompany Payables of the
Retained Company and its Subsidiaries shall be netted (the "Retained Company
Intercompany Balance"), (ii) the Unpaid Intercompany Receivables and the Unpaid
Intercompany Payables of AHC and its Subsidiaries shall be netted the ("AHC
Intercompany Balance") and (iii) whichever amount set forth in clause (i) or
(ii) represents a net payable shall be paid by AHC or the Retained Company, as
applicable.

            (b) The Specified Intercompany Amounts shall be settled in the
manner set forth in Schedule 4.01(n)(iii) to the Merger Agreement. For purposes
of this Agreement, Specified Intercompany Amounts shall mean the intercompany
receivables and payables identified as such Schedule 4.01(n)(iii) to the Merger
Agreement.

            5.3 Access to Information. From and after the Time of Contribution,
each of Axion and AHC shall afford to the other and to the other's
representatives reasonable access and duplicating rights (at the requesting
party's expense) during normal business hours and upon reasonable advanced
notice to all information within the possession or control of any member of
Axion and its Subsidiaries or AHC and its Subsidiaries, as the case may be,
relating to the business, Assets or Liabilities as they existed prior to the
Time of Contribution or relating to or arising in connection with the
relationship between the constituent elements of Axion and its Subsidiaries, on
the one hand, and AHC and its Subsidiaries, on the other hand, on or prior to
the Time of Contribution, insofar as such access is reasonably required for a
reasonable purpose, subject to the provisions in the Documents regarding the
confidentiality of information. Without limiting the foregoing, information may
be requested under this Section 5.3 for audit, accounting, claims, litigation
and Tax purposes, as well as for purposes of fulfilling disclosure and reporting
obligations.

            5.4 Valuations. At the Effective Time, Axion shall deposit, or cause
to be deposited, into escrow with Cravath, Swaine & Moore (the "Valuation Escrow
Agent"), and the Valuation Escrow Agent shall acknowledge receipt of, copies of
the valuations prepared by Ernst & Young and all supporting documents (i)
prepared in connection with the distribution of the capital stock of OnCare on
December 31, 1995 to the stockholders of Axion and (ii) regarding the Acquired
Businesses and the OPUS Station Business (collectively, the "Valuations"). The
Escrow Valuation Agent shall hold the Valuations in its possession until
requested by either Axion or AHC in writing to deliver copies of such Valuations
in accordance with the provisions of this Section 5.4. Either Axion or AHC may
request the release of the applicable Valuations if any information contained in
such Valuations and not otherwise available to the requesting party is relevant
to the resolution of any issue that has been raised in any audit or examination
by any Taxing authority, or in any claim, action, suit, inquiry, investigation
or proceeding relating to any such

audit or examination or to any other claim, action, suit, inquiry, investigation
or proceeding to which such Valuations may be relevant.

                                   ARTICLE VI

                                EMPLOYEE MATTERS

            6.1 Transferred Employees. Exhibit A sets forth the name, title and
current employer of each employee of AHC and each employee of Axion, OPUS, OTN
and OTNC whose employment will be transferred to AHC effective upon the Time of
Distribution, such transfer being effected upon the terms and conditions set
forth below in this Section 6.1 (all such employees hereinafter referred to as
"Transferred Employees"). It is intended that all employees of Axion, OPUS, OTN
and OTNC who are not listed on Exhibit B shall be deemed Transferred Employees
whether or not listed on Exhibit A. Prior to the Time of Distribution, AHC shall
offer employment to each employee of Axion, OPUS, OTN and OTNC set forth on
Exhibit A on such terms and conditions (including salary and benefit level) that
are substantially equivalent to the terms and conditions of the employee's
employment with Axion, OPUS, OTN or OTNC, as the case may be, immediately prior
to the Time of Distribution. Any Transferred Employee not actively-at-work as of
the date immediately following the Time of Distribution shall nonetheless be
deemed to be an employee of AHC as of such date for all purposes and shall be
covered under the benefit plans and arrangements of AHC to the fullest extent
permitted by such plans and arrangements. To the extent any Transferred Employee
is not able to be covered under any benefit plans or arrangements of AHC to the
same extent that such Transferred Employee would have been covered had he or she
not been included as a Transferred Employee, AHC shall bear full responsibility
to provide the level of benefits that such Transferred Employee would have
otherwise received. AHC shall recognize each Transferred Employee's prior
service with Axion, AHC, OPUS, OTN and OTNC and all members of Axion's
controlled group within the meaning of Section 414(b), (c), (m), and (o) of the
Code for all purposes under each employee benefit plan, policy or arrangement of
AHC. AHC shall be solely liable for all liabilities, costs and expenses arising
from any Transferred Employee's failure or inability, for any reason, to accept
AHC's offer of employment and commence or continue such employment with AHC
following the Time of Distribution,

                                                                              22


including any and all severance or termination benefits, benefit continuation
obligations, or employment-related claims.

            6.2 Continuing Axion Employees. Exhibit B sets forth the name,
title, annual base salary and current employer of each employee of Axion, AHC,
OPUS, OTN and OTNC who is intended to be a continuing employee of Axion on and
after the Time of Distribution (each a "Continuing Axion Employee").

            6.3 Savings Plan. Immediately prior to the Time of Distribution, the
Axion, Inc. 401K Profit Sharing Plan (the "Axion 401K Plan") shall be divided
into two plans, each plan substantially identical to the Axion 401K Plan. One
such plan shall be maintained by Axion and shall cover only those participants
who are Continuing Axion Employees (the "New Axion 401K Plan") and one such plan
shall cover all other participants in the Axion 401K Plan, including all
participants who are Transferred Employees, retirees and vested terminated
participants in the Axion 401K Plan on the Time of Distribution (the "AHC 401K
Plan"). As of the Time of Distribution, the AHC 401K Plan shall be transferred
to and assumed by AHC. As soon as practicable following the Time of
Distribution, Axion shall cause an amount in cash (or property acceptable to
AHC) to be transferred from the trust under the Axion 401K Plan to the trust
under the AHC 401K Plan equal to the sum of the account balances of (i) all
Transferred Employees, (ii) all retirees and (iii) all vested terminated
participants in the Axion 401K Plan with account balances under the Axion 401K
Plan. Assets relating to the accounts of Continuing Axion Employees shall be
retained by the Axion 401K Plan trust which shall be renamed the New Axion 401K
Plan Trust. Axion and AHC shall cooperate in good faith to expedite the
trust-to-trust transfer and to assure the ongoing operation and administration
of the New Axion 401K Plan and the AHC 401K Plan.

            6.4 Medical and Dental Benefits. Effective as of the Time of
Distribution, Axion shall (a) cause the Transferred Employees to cease coverage
under and participation in the Aetna Medical and Dental Plan and the underlying
insurance policy or policies, Axion Pharmaceuticals, Inc. (as amended to be the
Oncology Therapeutics Network Corporation) Flexible Employee Benefit Plan and
the Axion Health Care Inc. Flexible Employee Benefit Plan (the "Axion Health
Plan") and (b) cause the

                                                                              23


Axion Health Plan to cover only the Continuing Axion Employees. Effective as of
the Time of Distribution, AHC shall establish a medical and dental plan and a
corresponding Code Section 125 plan (the "AHC Health Plan") substantially
equivalent to the Axion Health Plan to cover the Transferred Employees (and
their eligible dependents) on the same basis and subject to the same conditions
that would have applied to such Transferred Employees (and their dependents)
absent the Distribution. The AHC Health Plan shall waive any waiting period
requirements and any pre-existing condition and actively-at-work exclusions and
shall provide that any expenses incurred on or before the Time of Distribution
shall be taken into account for purposes of satisfying applicable deductible,
coinsurance and maximum out-of-pocket provisions. Subject to the indemnification
provisions of Section 6.7, Axion shall be responsible for providing COBRA
coverage to any former employee, retiree or COBRA beneficiary entitled to such
coverage under any Axion welfare benefit plan as of the Time of Distribution.

            6.5 Other Welfare Benefits. Effective as of the Time of
Distribution, the Standard Insurance Life and Accidental Death & Dismemberment
Plan shall be transferred to and assumed by AHC and each Transferred Employee
(and his or her dependents) shall continue to participate in such plans on the
same terms that would have applied absent the Distribution. As of the Time of
Distribution, and subject to completion of the Merger, each Continuing Axion
Employee shall receive similar welfare benefits under the plans of BMS which
apply to similarly situated employees of BMS. No Transferred Employee shall be
subject to any waiting period with respect to such coverage under such welfare
plans which would not have applied absent his or her transfer of employment to
AHC.

            6.6 Disability Coverage. As of the Time of Distribution, the
Standard Insurance Long Term Disability Plan and any and all liabilities
associated with short term disability coverage or wage continuation thereunder
shall be transferred to and assumed by AHC. No Transferred Employee shall be
subject to any waiting period or pre-existing condition exclusion with respect
to such disability coverage which would not have applied absent his or her
transfer of employment to AHC. In accordance with the foregoing, AHC shall be
responsible for providing short-term and long-term disability benefits to each
Transferred Employee who is or becomes disabled before, on or after the Time of
Distribution and each former employee of Axion who becomes

                                                                              24


disabled before the Time of Distribution regardless of whether such former
employee would have been a Transferred Employee if he or she had not become
disabled. As of the date immediately following the Time of Distribution, and
subject to completion of the Merger, each Continuing Axion Employee shall be
eligible to participate in the short-term and long-term disability coverage
provided under the plans and policies of BMS subject to the same coverage levels
and other terms and conditions (including waiting periods and pre-existing
condition exclusions) as a newly hired employee of BMS.

            6.7 Indemnification. From and after the Time of Distribution AHC
shall indemnify, defend and hold harmless the BMS Indemnified Parties (as such
term is defined in the Indemnification Agreement) from and against, and pay or
reimburse the BMS Indemnified Parties for, all losses, liabilities, damages,
deficiencies, obligations, fines, expenses, claims, demands, actions, suits,
proceedings, judgments or settlements, whether or not resulting from third party
claims, including interest and penalties recovered by a third party with respect
thereto and out-of-pocket expenses and reasonable attorneys and accountants'
fees and expenses incurred in the investigation or defense or any of the same or
in asserting, preserving or enforcing any of the rights of BMS Indemnified
Parties hereunder, suffered by any of the BMS Indemnified Parties who or which
may seek indemnification under this Section 6.7, as incurred, relating to or
arising from (a) any employment-related claim of any kind (including any
employment benefit claim or any severance claim under the Oncology Therapeutics
Network Corporation Officer Severance Plan or any other severance or termination
pay plan or arrangement) involving any Transferred Employee, Continuing Axion
Employee or any other employee, retiree, former employee, applicant for
employment of Axion, AHC, OPUS, OTN, OTNC or any of their respective affiliates
and any predecessor of any such entity and any of such individual's
beneficiaries or dependents covered under any plan maintained by Axion or its
affiliates arising out of or relating to any event or state of facts occurring
or existing on or before the Time of Distribution; (b) any employment-related
claim of any kind (including any employee benefit claim or any severance claim
under any severance or termination pay plan or arrangement) involving any
Transferred Employee or any other employee, retiree, former employee or
applicant for employment with AHC and any of such individual's beneficiaries or
dependents covered under any plan maintained by AHC or its affiliates and

arising out of or relating to any event or state of facts occurring or existing
on or after the Time of Distribution; (c) any claim for severance, salary
continuation or other termination benefits payable in respect of any termination
or deemed termination of the employment of any Transferred Employee or
Continuing Axion Employee arising from or relating to the transactions
contemplated by this Agreement or the Merger Agreement or any transfer of such
employee's employment in connection therewith, regardless of whether such claim
is deemed to arise before, on or after the Time of Distribution; (d) any claim
or expense incurred with respect to any Transferred Employee relating to any
Benefit Plan or any successor plan or any accrued liabilities for payroll taxes
which arise before, on or after the Time of Distribution; (e) any claim or
expense incurred with respect to any former employee whose employment terminated
prior to the Time of Distribution or any COBRA beneficiary who is not a
Continuing Axion Employee relating to any Benefit Plan or any successor plan or
any accrued liabilities for payroll taxes or employee contributions to any
Benefit Plan which arise prior to the Time of Distribution; and (f) any claim or
expense incurred with respect to any Transferred Employee, Continuing Axion
Employee or former employee relating to workers compensation liability where the
claim arose with respect to an event occurring prior to the Time of
Distribution.

                                   ARTICLE VII

                                   CONDITIONS

            The obligations of Axion to consummate the Distribution shall be
subject to the fulfillment of each of the following conditions:

            (a) All the transactions or obligations contemplated by Articles III
and IV to be consummated or performed at or prior to the Time of Distribution
shall have been successfully consummated or so performed.

            (b) Each condition to the closing of the Merger set forth in Article

the Distribution) shall have been satisfied (or waived by the party for whose
benefit such condition exists).

            (c) The Board of Directors of Axion shall be reasonably satisfied
that, after giving effect to the Distribution, (i) AHC will not be insolvent and
will not have unreasonably small capital with which to engage in its businesses
and (ii) Axion's surplus would be sufficient to permit, without violation of
Section 170 of the Delaware General Corporation Law, the Distribution.

            (d) All filings required to be made with, and all consents,
approvals and authorizations required to be obtained from, any Governmental
Entity in connection with the execution, delivery and performance of this
Agreement or the consummation of the Contributions, the Distribution or the
other transactions contemplated by this Agreement shall have been made or
obtained.

            (e) No temporary restraining order, preliminary or permanent
injunction or other order issued by any court of competent jurisdiction or other
legal restraint or prohibition preventing the consummation of the Distribution
shall be in effect (each party agreeing to use all reasonable best efforts to
have any such order reversed or injunction lifted).

                                  ARTICLE VIII

                                   TAX MATTERS

                           Indemnification Procedures

            SECTION 4.01. Third Party Claims. (a) In order for any person (the
"indemnified party") to be entitled to any indemnification provided for under
this Agreement in respect of, arising out of or involving a claim made by any
person against the indemnified party (a "Third Party Claim"), such indemnified
party must notify the indemnifying party in writing, and in reasonable detail,
of the Third Party Claim within 20 business days after receipt by such
indemnified party of written notice of the Third Party Claim; provided, however,
that failure to give such notification shall not affect the indemnification
provided hereunder except to the extent the indemnifying party shall have been
actually prejudiced as a result of such failure (except that the indemnifying
party shall not be liable for any expenses incurred during the period in which
the indemnified party failed to give such notice); and provided, further,
however, that with respect to any matter for which the AHC Indemnifying Parties
are the indemnifying party, the AHC Indemnifying Parties shall be deemed to have
received notice hereunder with respect to all matters concluded or initiated
prior to, or otherwise pending at, the Time of Contribution. Thereafter, the
indemnified party shall deliver to the indemnifying party, promptly after the
indemnified party's receipt thereof, copies of all notices and documents
(including court papers) received by the indemnified party relating to the Third
Party Claim.

      (b) If a Third Party Claim is made against an indemnified party pursuant
to the terms of this Agreement, the indemnifying party will be entitled to
participate in the defense thereof and, if it so chooses, to assume the defense
thereof (at the expense of the indemnifying party) with counsel selected by the
indemnifying party. Should the indemnifying party so elect to assume the defense
of a Third Party Claim, the indemnifying party will not be liable to the
indemnified party for any legal expenses subsequently incurred by the
indemnified party in connection with the defense thereof. If the indemnifying
party assumes such defense, the indemnified party shall have the right to
participate in the defense thereof and to employ counsel, at its own expense,
separate from the counsel employed by the indemnifying party, it being
understood that the indemnifying party shall control such defense. The
indemnifying party shall be liable for the fees and expenses

                                                                              12


of counsel employed by the indemnified party for any period during which the
indemnifying party has not assumed the defense thereof (other than during any
period in which the indemnified party shall have failed to give notice of the
Third Party Claim as provided above). If the indemnifying party chooses to
defend or prosecute a Third Party Claim, all the parties hereto shall cooperate
in the defense or prosecution thereof. Such cooperation shall include the
retention and (upon the indemnifying party's request) the provision to the
indemnifying party of records and information which are reasonably relevant to
such Third Party Claim, and making employees available on a mutually convenient
basis to provide additional information and explanation of any material provided
hereunder. If the indemnifying party chooses to defend or prosecute any Third
Party Claim, the indemnified party will agree to any settlement, compromise or
discharge of such Third Party Claim which the indemnifying party may recommend
and which by its terms obligates the indemnifying party to pay the full amount
of liability in connection with such Third Party Claim; provided, however, that
the indemnifying party shall not consent to entry of any judgment or enter into
any settlement (x) that provides for injunctive or other nonmonetary relief
affecting the indemnified party or (y) that does not include as an unconditional
term thereof the giving by each claimant or plaintiff to such indemnified person
of a release from all liability with respect to such claim. Whether or not the
indemnifying party shall have assumed the defense of a Third Party Claim, the
indemnified party shall not admit any liability with respect to, or settle,
compromise or discharge, such Third Party Claim without the indemnifying party's
prior written consent (which consent shall not be unreasonably withheld).

            SECTION 4.02. Other Indemnifiable Losses. In order for an
indemnified party to be entitled to any indemnification provided for under this
Agreement in respect of a claim that does not involve a Third Party Claim being
asserted against or sought to be collected from such indemnified party, the
indemnified party shall deliver notice of such claim with reasonable promptness
to the indemnifying party. The failure by any indemnified party to so notify the
indemnifying party shall not relieve the indemnifying party from any liability
which it may have to such indemnified party under this Agreement, except to the
extent that the indemnifying party shall have been actually prejudiced by such
failure. If the indemnifying party does not notify the indemnified party within
60 calendar days

                                                                              13


following its receipt of such notice that the indemnifying party disputes in
good faith its liability to the indemnified party under this Agreement, such
claim specified by the indemnified party in such notice shall be conclusively
deemed a liability of the indemnifying party under this Agreement and, subject
to the provisions of Section 2.02(b), the indemnifying party shall pay the
amount of such liability to the indemnified party on demand or, in the case of
any notice in which the amount of the claim (or any portion thereof) is
estimated, on such later date when the amount of such claim (or such portion
thereof) becomes finally determined. If the indemnifying party has timely
disputed its liability with respect to such claim, as provided above, the
indemnifying party and the indemnified party shall proceed in good faith to
negotiate a resolution of such dispute and, if not resolved through
negotiations, such dispute shall be resolved by litigation in an appropriate
court of competent jurisdiction subject to the provisions of Sections 6.14 and
6.15.

            SECTION 4.03. Indemnifiable Losses Net of Third Party Recoveries.
The amount of any Indemnifiable Losses for which indemnification is provided
under this Agreement shall be net of any amounts actually recovered prior to the
date of actual notice of such Indemnifiable Loss pursuant to Section 4.01 or
4.02 by the indemnified party under third-party insurance policies with respect
to such Indemnifiable Losses. Any amounts recovered by an indemnified party
under third-party insurance policies with respect to an Indemnifiable Loss
subsequent to the date of actual notice of such Indemnifiable Loss pursuant to
Section 4.01 or 4.02 shall be paid promptly to the relevant indemnifying party.
An insurer who would otherwise be obligated to pay any claim shall not be
relieved of the responsibility with respect thereto or, solely by virtue of the
indemnification provisions hereof, have any subrogation rights with respect
thereto.

            SECTION 4.04. Indemnifiable Losses Payable on After-Tax Basis. All
Indemnifiable Losses (and any amounts payable pursuant to the second sentence of
Section 4.03) shall be determined, and all indemnification payments shall be
made, on an after-tax basis to the indemnified party, provided that each
indemnified party shall be assumed to pay taxes at the highest applicable
effective federal, state and local rate and each indemnified party shall
initially determine whether to treat a particular item of expense as tax
deduction or a particular receipt as taxable income, and

shall submit any such determination for approval to the indemnifying party
reasonably promptly. If the indemnifying party, within 30 days after receipt of
such notification, notifies the indemnified party that it does not approve of
such determination, then AHC and BMS shall proceed in good faith to negotiate a
resolution of such dispute and, if not resolved through negotiations, such
dispute shall be resolved by litigation in an appropriate court of competent
jurisdiction.

                                    ARTICLE V

                                    Covenants

            SECTION 5.01. Confidentiality. The Confidentiality Agreement will
terminate, according to its terms, as of the Effective Time. Immediately from
and after the Effective Time, except as otherwise provided in this Agreement,
(a) the BMS Indemnified Parties will, and will cause their Subsidiaries and
affiliates (and their respective officers, employees, accountants, counsel,
financial advisors and other representatives to whom they disclose such
information) to hold in strict confidence and not use or disclose for five years
from the Effective Time (i) all confidential Evaluation Material (as defined in
the Confidentiality Agreement) in the possession of the BMS Indemnified Parties
or to which the BMS Indemnified Parties are given access pursuant to the
Confidentiality Agreement or Section 6.03 of the Merger Agreement to the extent
that such Evaluation Material relates to the AHC Companies or to OnCare and its
Subsidiaries and (ii) all confidential and proprietary information relating to
the Acquired Assets and the Assumed Liabilities in the possession of the BMS
Indemnified Parties, and (b) the AHC Indemnified Parties will, and will cause

of this Section 5.01 by the disclosing party or by any Subsidiary or any
affiliate of the disclosing party, (ii) received from a third party not bound by
any confidentiality requirement with the other parties hereto, (iii) which are,
or become, independently developed by such party without violating any of its
obligations under this Section 5.01, (iv) required by applicable law to be
disclosed by such party, or (v) necessary to establish such party's rights under

the case of clauses (iv) and (v), the person intending to make disclosure of
confidential ]information will promptly notify the party to whom it is obliged
to keep such information confidential and, to the extent practicable, provide
such party a reasonable opportunity to prevent such public disclosure.

            SECTION 5.02. Merger, Consolidation and Related Matters. (a) AHC and
each of the 81% AHC Subsidiaries agrees that, unless BMS shall otherwise consent

      affairs or (B) in the case of any 81% AHC Subsidiary, liquidate, dissolve
      or wind up its affairs unless the assets of such 81% AHC Subsidiary (or,
      if such 81% AHC Subsidiary shall not be wholly owned, a proportionate
      amount of such assets equal to the direct and indirect ownership interest
      of AHC in such 81% AHC Subsidiary) shall have been distributed to or
      otherwise acquired by AHC and/or any other 81% AHC Subsidiary;

            (ii) (A) merge with or into or consolidate with any other person, or

      of the sale of the capital stock of any Subsidiary) to any other person
      (in each case, whether in one or a series of transactions), unless, in
      each case, such person explicitly agrees to assume the obligations of AHC
      and the 81% AHC Subsidiaries under this Agreement, the Tax Matters
      Agreement or the Escrow Agreement pursuant to an agreement reasonably
      satisfactory in form and substance to BMS and its counsel;

            (iii) engage in any recapitalization or restructuring pursuant to

      capital stock or effect any other distribution (by means of dividend,
      redemption or otherwise) in respect of its capital stock (other than, in
      the case of any 81% AHC Subsidiary, any such distribution to AHC);

            (iv) enter into any transactions with affiliates of AHC or any 81%
      AHC Subsidiary unless (1) any such transaction is between or among AHC and
      the 81% AHC Subsidiaries or (2) the terms of such transactions are fair
      and reasonable to AHC or the 81% AHC Subsidiaries, as the case may be, as
      in a comparable transaction made on an arms' length basis between
      unaffiliated parties; or

            (v) agree to or otherwise suffer any of the foregoing in (i), (ii),
      (iii) or (iv) above or otherwise take any action or fail to take any
      action designed to restrict, reduce or otherwise limit the rights of the
      BMS Indemnified Parties under this Agreement, the Tax Matters Agreement or
      the Escrow Agreement or the ability of any BMS Indemnified Party to
      collect any amount owed to it under this Agreement, the Tax Matters
      Agreement or the Escrow Agreement.

            (b) For purposes of this Section 5.02, AHC and its Subsidiaries
acknowledge and agree that OnCare and its Subsidiaries shall be considered
affiliates of AHC and the 81% AHC Subsidiaries.

            (c) AHC shall cause each of its Subsidiaries that shall be or become
an 81% AHC Subsidiary on or after the date hereof to enter into an agreement,
reasonably satisfactory in form and substance to both BMS and its counsel and
AHC and its counsel, pursuant to which such Subsidiary shall agree to be bound
by the terms of each of this Agreement, the Tax Matters Agreement and the Escrow
Agreement as if such Subsidiary were named an 81% AHC Subsidiary herein and
therein.

            (d) The provisions of this Section 5.02 shall terminate as of the
sixth anniversary of the Effective Time; provided, however, that if as of such
sixth anniversary an audit or contest of any Federal income tax return of the
Affiliated Group (as defined in the Tax Matters Agreement) for any taxable year
ending on or before the day on which the Effective Time occurs is in process,
the provisions of this Section 5.02 shall not terminate until such time as any
Tax Claims (as defined in the Tax Matters Agreement)

the part of any of the parties hereto in exercising any right, power or
privilege hereunder will operate as a waiver thereof, nor will any waiver on the
part of any of the parties hereto of any right, power or privilege hereunder

            WHEREAS, the Board of Directors of Axion has approved an agreement
and plan of reorganization and distribution embodied in the form of the

Stock and the holders of Axion Preferred Stock all the then outstanding shares
of AHC Preferred Stock (the "Distribution");

            WHEREAS, the execution and delivery of this Agreement by the parties
hereto is a condition to the obligations of the parties to the Merger Agreement
to consummate the Merger;

            WHEREAS, BMS, BMS Sub and Axion have entered into an Amended and
Restated Agreement and Plan of Merger dated as of August 2, 1996 (the "Merger
Agreement") pursuant to which, following the Distribution, BMS Sub shall merge
with and into Axion (the "Merger") with Axion as the surviving corporation (the
"Surviving Corporation") and in connection with which certain parties will
execute the Escrow Agreement and the Indemnification Agreement (the
Contributions, the Distribution, the Merger and the related agreements and
transactions, the "Transactions");

            WHEREAS, for Federal income tax purposes, it is intended that (a)
the Distribution shall qualify as a tax-free spinoff under Section 355 of the
Internal Revenue Code of 1986, as amended (the "Code") and (b) the Merger shall
qualify as a reorganization within the meaning of Section 368(a)(1)(B) of the
Code; and

            WHEREAS, BMS and Axion desire to allocate the liability for the
Taxes (as defined below) of members of the Affiliated Group for any taxable
period (including short taxable periods and any portion of any taxable period)
which period (or portion) ends on or before the day on which the Effective Time
occurs (a "Pre-Merger Tax Period"), which liability is secured by the escrow
created pursuant to the Escrow Agreement attached to the Merger Agreement, and
to provide for certain other Tax-related matters;

            NOW, THEREFORE, in consideration of the covenants contained herein,
the parties agree as follows:

            1. Indemnification. (a)(i) AHC, the 81% AHC Subsidiaries and the
Former Axion Stockholders (collectively, the "AHC Indemnifying Parties") shall
jointly and severally indemnify and hold harmless BMS, the Surviving
Corporation, OPUS, OTNC, the Partnership, their affiliates and each of their
respective officers, directors, employees, stockholders, agents and
representatives (collectively, the

                                                                               6


"BMS Indemnified Parties") from all liabilities for Federal, state, local,
foreign and other governmental taxes, assessments, duties, fees, levies or
similar charges of any kind including all interest, penalties and additions
imposed with respect to such amounts (collectively, "Taxes") imposed on Axion,
OPUS, OTNC or any member of the Affiliated Group (whether imposed directly or by
reason of United States Treasury Regulations Section 1.1502-76 or similar
provisions) (A) for any Pre-Merger Tax Period, including any Pre-JV Sales Taxes
(but excluding any Retained Tax Liabilities), which are in each case unpaid as
of the Effective Time (such indemnified Taxes, the "Pre-Merger Taxes), (B) with
respect to the Contributions, (C) as a result of the Distribution, (D) as a
result of the provision of the OPUS Station Data to AHC, OnCare or any of their
assignees, (E) with respect to the OPUS License Agreement, or (F) in respect of
the transfer of assets or rights from OnCare or any of its subsidiaries or
affiliates or any other affiliate of Axion and its subsidiaries to Axion prior
to the Distribution. The AHC Indemnifying Parties shall also jointly and
severally indemnify the BMS Indemnified Parties from all liabilities for fifty
percent (50%) of the excess of (I) any liability for any unpaid Taxes (other
than JV Sales Taxes) as of June 30, 1996 imposed on the Partnership for all
periods up to and including June 30, 1996 over (II) $225,000, and 100% of any
liability for JV Sales Taxes paid after June 30, 1996 in excess of $667,40;
provided, however, that no indemnification shall be payable with respect to any
JV Sales Taxes to the extent payment of such JV Sales Taxes increased the amount
of "Retained Cash" pursuant to clause (c) of the definition of "Retained Cash"
in the Distribution Agreement). "Retained Tax Liabilities" shall mean (W) any
income Tax liability (including any liability for any Tax measured by reference
to income) of OTNC (or the Affiliated Group) attributable to the allocation to
OTNC of Taxable income of the Partnership (whether or not such Taxes are paid
before or after the Effective Time) and any other Taxes to the extent directly
attributable to the operation of the Partnership, in each case for the period
beginning on July 1, 1996, and ending on the day on which the Effective Time
occurs and in each case determined in accordance with the principles of Section
3(a) and (for the avoidance of doubt), in the case of Taxes measured by
reference to income, by assuming that such income is subject to Tax at the
highest applicable Federal, state and local tax rate as provided by Section 1(c)
hereof, (X) any income Tax liability (including any liability for any Tax
measured by reference to income) to the extent

                                                                               7


directly attributable to the reallocation of Partnership income by the IRS or
any other governmental agency from Bristol-Myers Oncology Therapeutics Network
Corporation to OTNC, (Y) all liabilities for any unpaid Taxes as of June 30,
1996 imposed on the Partnership for all periods up to and including June 30,
1996 that are not indemnified by the AHC Indemnifying Parties pursuant to the
preceding sentence, and (Z) any Tax liabilities relating to the operations,
assets or activities of a BMS Entity (other than the Partnership). "Pre-JV Sales
Taxes" shall mean any liability of Axion with respect to unpaid sales and use
Taxes on sales prior to the date of formation of the Partnership. "JV Sales
Taxes" shall mean any liability of the Partnership with respect to unpaid sales
and use Taxes on sales prior to August 1, 1994.

           (ii) BMS, Axion, OTNC, OPUS and the Partnership (collectively, the
"BMS Indemnifying Parties") shall jointly and severally indemnify and hold
harmless AHC, the Subsidiaries, their affiliates and each of their respective
officers, directors, employees, stockholders, agents and representatives
(collectively, the "Axion Indemnified Parties") (A) from all liability for Taxes
imposed on Axion, OTNC, OPUS or the Partnership for any Post-Merger Tax Period
and (B) for any Retained Tax Liabilities.

            (b) Notwithstanding anything to the contrary set forth herein, the
indemnification obligations of the Former Axion Stockholders under this
Agreement shall be limited to the amounts held in the BMS Stock Escrow Fund (as
such term is defined in the Escrow Agreement). The limitations on the Former
Axion Stockholders' liability under this Section 1(b) shall not apply to any
liability for Taxes relating to or arising from fraud or any misrepresentation
or breach of which Axion, AHC, the 81% AHC Subsidiaries or their respective
officers and directors had knowledge or any intentional failure to perform or
comply with any covenant (collectively, "fraud"), and AHC, the 81% AHC
Subsidiaries and the Former Axion Stockholders shall be jointly and severally
liable for all liabilities for Taxes with respect thereto; provided, however,
that a Former Axion Stockholder shall be liable for Taxes related to or arising
from fraud only with respect to any fraud by such Former Axion Shareholder.

            (c) All indemnified liabilities for Taxes and other losses shall be
determined, and all indemnification payments shall be made, on an after-tax
basis to the

indemnified party, provided that each indemnified party shall be assumed to pay
taxes at the highest applicable effective federal, state and local rate and each
indemnified party shall initially determine the amount of any claim for
indemnification and whether to treat a particular item of expense as a tax
deduction or a particular receipt as taxable income, and shall submit any such
determination for approval to the indemnifying party reasonably promptly. If the
indemnifying party, within 30 days after receipt of such notification, notifies
the indemnified party that it does not approve of such determination, then AHC
and BMS shall proceed in good faith to negotiate a resolution of such dispute
and, if not resolved through negotiations, such dispute shall be resolved by
litigation in an appropriate court of competent jurisdiction (subject to Section
20 of this Agreement).

            (d) Any indemnification payments due to the AHC Indemnified Parties
with respect to clause (W) of the definition of of "Retained Tax Liabilities"
shall, to the extent that payments in respect of such Retained Tax Liabilities
were made prior to the Effective Time, be paid within twenty (20) days of date
on which the Effective Time occurs.

            2. Control of Tax Matters. (a)(i) Except as provided in paragraph
(ii) below and subject to Section 3 below, Axion hereby designates, and agrees
to cause each of its Subsidiaries (including, without limitation, the
Partnership) to so designate, AHC as its agent to take any and all actions, at
AHC's sole expense, necessary or incidental to the preparation of Tax Returns,
the determination of Tax liability and the filing of any and all forms
(including, subject to Sections 2(d) and 3, any forms relating to any refund of
Taxes for which the AHC Indemnifying Parties are liable pursuant to Section
1(a)(i) (collectively, "AHC Taxes)) (A) relating to all Pre-Merger Tax Periods
(other than the portion of any Pre-Merger Tax Period that is a Straddle Period,
as defined below) and (B) until December 31, 1996, relating to all Pre-JV Sales
Taxes and all JV Sales Taxes (provided that AHC agrees to use reasonable
commercial efforts to eliminate, prior to December 31, 1996, all liabilities for
JV Sales Taxes and Pre-JV Sales Taxes); provided that Axion shall only be deemed
to have made such designation with respect to Tax Returns signed by Ernst &
Young LLP, or another nationally recognized accounting firm selected by AHC and
reasonably acceptable to BMS as return preparers and to other forms or

                                                                               9


determinations of Tax liability the accuracy and completeness of which have been
certified by Ernst & Young LLP, or another nationally recognized accounting firm
selected by AHC and reasonably acceptable to BMS, to the same extent as if they
had been a return preparer.

          (ii) Notwithstanding the foregoing, AHC hereby designates, and agrees
to cause each of its Subsidiaries to so designate, BMS as its agent to take any
and all actions, at BMS's sole expense, necessary or incidental to the
preparation of Tax Returns, the determination of Tax liability and the filing of
any and all forms (including any forms relating to any refund of Taxes for which
the BMS Indemnifying Parties are liable pursuant to Section 1(a)(ii)
(collectively, "BMS Taxes")) relating (A) to any Post-Merger Tax Period, (B) to
the portion of any Pre-Merger Tax Period that is a Straddle Period, provided,
however, that any determination and reporting of Taxes for any Straddle Period
shall be made jointly by AHC and BMS, (C) solely to Taxes payable by the
Partnership for any taxable period other than, with respect to periods prior to
December 31, 1996, all JV Sales Taxes, and (D) to any Pre-JV Sales Taxes that
remain unpaid after December 31, 1996.

            (b) Prior to the Effective Time, Axion shall, and shall cause AHC
and each other member of the Affiliated Group to, (i) accurately prepare and
timely file with the relevant Taxing Authority all Tax Returns and reports
("Post-Signing Returns") required to be filed by Axion or any member of the
Affiliated Group at or before the Effective Time, (ii) timely pay all Taxes due
and payable by Axion or any member of the Affiliated Group at or before the
Effective Time, (iii) make adequate provision on their books and records, to the
extent required in accordance with GAAP, for all Taxes due and payable after the
Effective Time, and (iv) promptly notify BMS of any action, suit, proceeding,
claim or audit pending against or with respect to Axion, AHC or any other member
of the Affiliated Group in respect of any Taxes where there is a reasonable
possibility of a determination or decision which could have a material adverse
effect on Axion's or any of its affiliate's, Tax liabilities or Tax attributes.

            (c) Except with the prior written consent of BMS, which shall not be
unreasonably withheld, and subject to Section 3, each of Axion and AHC shall
refrain, and shall cause each of its respective subsidiaries to refrain, from
(i) making any material Tax election other than consistent

                                                                              10


with past practice that would bind BMS or any member of the BMS affiliated group
or otherwise materially affect the Tax liability of the Affiliated Group or (ii)
making, filing or amending any material Tax Return that includes any Pre-Merger
Tax Period that (A) is inconsistent with the existing and historic method used
by the Affiliated Group in calculating the taxable income of the Affiliated
Group, or (B) would otherwise materially affect the Tax liability of BMS, Axion
or any direct or indirect subsidiary of BMS or Axion for any Tax period (or
portion) that is not a Pre-Merger Tax Period (a "Post-Merger Tax Period").

            (d)  [Intentionally omitted]

            (e)(i) If (A) a claim relating to Taxes (a "Tax Claim") shall be
made by any Taxing authority, which, if successful, might result in an indemnity
payment to any BMS Indemnified Party pursuant to Section 1(a)(i) of this
Agreement (other than a Tax Claim relating solely to Taxes payable by the
Partnership), (B) the AHC Indemnifying Parties admit in writing their obligation
to indemnify the BMS Indemnified Party for the Tax Claim, (C) (i) no proceeding
shall have been commenced and no petition shall have been filed seeking relief
in respect of AHC or any of its Subsidiaries, or of a substantial part of their
respective property or assets, under Title 11 of the United States Code as now
constituted or hereafter amended, or seeking the appointment of a receiver,
trustee or similar official for AHC or any of its Subsidiaries or for a
substantial part of their respective property or assets, or seeking the winding
up or liquidation of AHC or any of its Subsidiaries and (ii) none of AHC or any
of its Subsidiaries shall have made a general assignment for the benefit of
creditors or become unable, admitted in writing its inability or failed
generally to pay its debts as they become due, (D) the Tax Claim is the only
material Tax issue involving the BMS Indemnified Party involved in a proceeding,
and (E) Ernst & Young LLP, or another nationally recognized accounting firm
selected by AHC and reasonably acceptable to BMS, certifies in writing to BMS
that there is a reasonable basis for the defense against such Tax Claim, then
AHC shall control all proceedings taken in connection with the Tax Claim
(including selection of counsel) and, without limiting the foregoing, may in its
sole discretion pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with any Taxing authority with respect
thereto, and may, in its sole discretion, either pay such Tax Claim and sue for
a refund



<PAGE>
 

<PAGE>

                                                                              11


where applicable law permits such refund suits or contest the Tax Claim in any
permissible manner. In such a case AHC shall keep the BMS Indemnified Party
reasonably informed of developments in the proceeding. In all cases involving a
Tax Claim that might result in an indemnity payment to any BMS Indemnified
Party, BMS shall reasonably promptly notify AHC thereof and each BMS Indemnified
Party shall use its reasonable best efforts to cause that Tax Claim to be
determined in a proceeding separate from other Tax issues involving the BMS
Indemnified Party or any affiliate thereof. If the BMS Indemnified Party cannot
accomplish this separation of the Tax Claim so that such claim and other
material Tax Claims involving the BMS Indemnified Party or any affiliate thereof
have to be determined in a single proceeding, or if any of the other conditions
set forth in the first sentence of this Section 2(e)(i) are not satisfied, then,
to the maximum extent permitted, AHC shall be entitled to participate in the
proceeding through its own counsel and the BMS Indemnified Party shall consult
with AHC with regard to pursuing or foregoing administrative appeals,
proceedings, hearings and conferences with any Taxing authority and whether or
not to pay the Tax Claim and sue for a refund or to contest the Tax in some
other manner. However, except as provided in the following sentence, decisions
as to the method of contesting Taxes in such a proceeding shall be made by the
BMS Indemnified Party but AHC shall control all other aspects of the contest,
including the decisions as to whether to settle or continue to contest the Tax
Claim. Notwithstanding the foregoing, without the consent of AHC the BMS
Indemnified Party shall not pursue such Tax Claim in a forum that requires the
payment of the disputed Taxes as a pre-condition to contesting such Tax Claim if
there is a forum available that does not require such payment, unless BMS
advances the amount of such Taxes until the time at which such Taxes are
considered to be payable pursuant to Section 9 of this Agreement.

          (ii) Subject to Section 2(e)(i) above, if a Tax Claim shall be made by
any Taxing authority, which, if successful, might result in an indemnity payment
to any Axion Indemnified Party pursuant to Section 1(a)(ii) of this Agreement,
then Axion or BMS shall control all proceedings taken in connection with the Tax
Claim (including selection of counsel) and, without limiting the foregoing, may
in its sole discretion pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with any Taxing authority with respect
thereto, and may, in its sole

                                                                              12


discretion, either pay such Tax Claim and sue for a refund where applicable law
permits such refund suits or contest the Tax Claim in any permissible manner. In
such a case Axion or BMS shall keep the Axion Indemnified Party reasonably
informed of developments in the proceeding.

            3. Refunds. Notwithstanding anything to the contrary in this
Agreement, AHC will not amend, and will cause each AHC Indemnifying Party not to
amend, any Tax return for any Pre-Closing Tax Period that would result in a
refund of Taxes (except a refund claim made as a precondition to contesting an
asserted Tax Claim for a Pre-Merger Tax Period (as defined below)), unless (i)
such refund claims in the aggregate do not exceed $500,000 or (ii) AHC places
the full amount of each such refund into an escrow account established solely to
secure any Tax Claim that may result from such refund claim and that will not,
without the consent of BMS (which consent shall not be unreasonably withheld),
terminate prior to the expiration of the applicable statute of limitations or,
if earlier, the date of a "determination" (as defined in Section 1313 of the
Code) with respect to such refund claim.

            AHC shall promptly pay to BMS the amount of any Tax refund relating
to BMS Taxes that is received by AHC or any of its Subsidiaries (a "BMS
Refund"). BMS shall promptly pay to AHC the amount of any Tax refund relating to
AHC Taxes that is received by BMS or any of its Subsidiaries (an "AHC Refund").

            4. Allocation Between Taxable Periods. (a) In the case of any
taxable period that includes but does not end on the day on which the Effective
Time occurs (a "Straddle Period"),

            (i) real, personal and intangible property Taxes, other than
      transfer and similar Taxes ("Property Taxes"), allocated to the Pre-Merger
      Tax Period shall be equal to the amount of such Property Taxes for the
      entire Straddle Period multiplied by a fraction, the numerator of which is
      the number of days during the Straddle Period that are in the Pre-Merger
      Tax Period and the denominator of which is the number of days in the
      Straddle Period; and

          (ii) all Taxes (other than Property Taxes) for the Pre-Merger Tax
      Period shall be computed based on an actual closing of the books as if
      such taxable period

                                                                              13


      ended as of the close of business on the Effective Date and, in the case
      of any Taxes attributable to the ownership of any equity interest in any
      partnership or other "flow through" entity, based on an actual closing of
      the books as if the taxable period of such partnership or other "flow
      through" entity ended as of the close of business on the Effective Date;
      provided, however, that all transfers and transactions (including Taxes
      attributable thereto) which occur to effectuate the Distribution or the
      Merger shall be allocated to the Pre-Merger Tax Period.

            (b) Without limiting the foregoing provisions of this Section 4
setting forth the principles for allocating income, gain, loss, deduction,
credits, events or transfers between Pre-Merger and Post-Merger Tax Periods, and
any Straddle Period, BMS, Axion and each of their relevant Subsidiaries, and AHC
and each of its Subsidiaries, (i) shall file, or cause to be filed, all relevant
Tax Returns and execute, or cause to be executed, such other documents as may be
required by any Taxing authority, on the basis that the Distribution and the
Merger shall occur for Tax purposes as of the close of business on the day
before the day on which the Effective Time occurs and shall refrain from taking
any position inconsistent with such basis with any Taxing authority unless the
relevant Taxing authority will not accept a Tax return filed on such basis, (ii)
each agree to report the Distribution as a tax-free spin-off under Section 355
of the Code and the Merger as a tax-free reorganization under Section 368 of the
Code on all Tax Returns, and to take no position inconsistent therewith, except
if there is a "determination" (as defined Section 1313 of the Code) to the
effect that such position is incorrect or as otherwise required to contest a
claim by a Taxing authority that such position is incorrect or to file amended
state or local Tax Returns as required by law by reason of an adverse
preliminary or final determination (including an audit assessment by a Federal
Taxing authority), and (iii) agree to file all Tax Returns on the basis that any
taxable period that includes the day on which the Effective Time occurs ends on
such date unless the relevant Taxing authority will not accept a Tax Return
filed on such basis.

            (c) The determination of all Taxes imposed on the Partnership for
all periods up to and including June 30, 1996, or for all periods beginning on
or after July 1, 1996,

shall be made on the principles set forth in Section 3(a) above.

            5. Cooperation. BMS, Axion and AHC each agree to cooperate with one
another and to cause each of its Subsidiaries to so cooperate, in a timely
manner consistent with existing practice, in filing any return, form or consent
contemplated by this Agreement. Each party also agrees to take, and will cause
the appropriate Subsidiary to take, such action or actions as each other party
may reasonably request with respect to the Tax matters contemplated by this
Agreement, including but not limited to the timely filing of requests for the
extension of time within which to file Tax Returns, and the signing of and
timely filing of such waivers, consents, forms, court petitions, refund claims,
complaints, powers of attorney and other documents needed from time to time in
order to file Tax Returns and defend, prosecute or resolve deficiencies or
claims as provided herein. Each of AHC and BMS further agrees to furnish timely,
and to cause each of its subsidiaries to so furnish, the other with any and all
information reasonably requested by the other in connection with this Agreement
and the transactions contemplated by this Agreement, whether such information
relates to a period before or after the Effective Time; provided, however, that
any valuations of OnCare, OPUS and AHC made by Axion or its advisors shall be
placed in escrow and shall be made available as provided in Section 5.4 of the
Distribution Agreement. Without limiting the generality of the foregoing
sentence, AHC specifically agrees to provide to BMS, reasonably promptly, copies
of any correspondence or notices received from the Internal Revenue Service or
any other Taxing authority with respect to Taxes of the Affiliated Group for a
Pre-Merger Tax Period, and BMS agrees to provide the same to Axion within the
same time period.

            Each party hereto shall retain all books and records relating to
Taxes until the later of (i) ten years after the Effective Time and (ii)
expiration of the applicable statute of limitations.

            6. Transfer Taxes. Axion shall cause AHC to pay or cause to be paid
all transfer, documentary, sales, use, registration, value-added and other
similar Taxes (including all applicable real estate transfer Taxes and real
property transfer gains Taxes) and related amounts (including any penalties,
interest and additions to any such Tax) incurred in connection with, or as a
result of, the Transactions.

AHC shall pay all New York State stock transfer taxes due with respect to the
Transactions, and shall be entitled to any rebate thereof.

            7. Post-Effective Time Restructurings. BMS shall refrain from, and
shall cause each BMS Indemnifying Party to refrain from, causing Axion, OTNC,
OPUS or the Partnership from taking any action between the Closing and the
beginning of the day after the day on which the Effective Time occurs, other
than in the ordinary course of business or as contemplated by the Merger
Agreement and the agreements, Documents and other items referred to in Section
9.06 of the Merger Agreement; provided, however, that BMS shall refrain from,
and shall cause each BMS Indemnifying Party to refrain from, undertaking the
restructuring of its ownership of Axion, OTNC, Bristol-Myers Oncology
Therapeutic Network, Inc. or the Partnership until the beginning of the day
after the day on which Effective Time occurs.

            8. Tax Sharing Agreements. As of the Effective Time, AHC shall cause
all Tax sharing agreements (other than this Agreement) or arrangements to which
Axion or any Subsidiary thereof (immediately before the Merger) is a party to be
terminated, including without limitation any formal or informal agreement or
arrangement with OnCare, with no further obligations or liabilities of Axion or
any such Subsidiary thereof.

            9. Tax Liabilities. For purposes of this Agreement, and for purposes
of the Escrow Agreement as it relates to Taxes, a liability for Taxes shall not
be deemed liquidated and therefore payable until the earlier of (i) the date
that a Tax Return has been filed as provided herein showing such Tax to be due
and payable (other than with respect to a Tax Claim for which BMS is required to
advance Taxes pursuant to the final sentence of Section 2(e)(i)) or (ii) there
shall be a "determination" (as defined in Section 1313 of the Code) that such
Tax is due and payable.

            10. Offsets. (a) No payment shall be required to be made by any AHC
Indemnifying Party to any BMS Indemnifying Party, or by any BMS Indemnifying
Party to any AHC Indemnifying Party, as the case may be, pursuant to this
agreement to the extent that there is an amount then due and payable under this
Agreement to an AHC Indemnifying Party by a BMS Indemnifying Party, or to a BMS
Indemnifying Party by an AHC Indemnifying Party, as the case may be.

            (b) The amount of any payment required to be made by any AHC
Indemnifying Party to any BMS Indemnified Party pursuant to this Agreement or
the Indemnification Agreement shall be reduced to the extent that Axion shall
actually have received, prior to the date such payment is required to be made,
an actual tax benefit in a Post-Merger Period by reason of a deduction resulting
from the disposition by a Former Axion Stockholder of shares of BMS Stock
acquired in the Merger in exchange for Axion Stock that was issued pursuant to
the exercise of an incentive stock option (within the meaning of Section 422 of
the Code). BMS shall cause Axion to claim any such deduction of which BMS or
Axion is aware, including, without limitation, pursuant to notice provided to
Axion by AHC.

            11. Assignment. Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise by any of the parties without the prior
written consent of the other parties. Subject to the preceding sentence, this
Agreement shall be binding upon, inure to the benefit of, and be enforceable by,
the parties hereto and their respective successors and assigns.

            12. Survival. The provisions of this Agreement shall survive the
Effective Time and remain in full force until all periods of limitations,
including any extension or waiver periods, for all Taxes covered by this
Agreement have expired.

            13. Notices. Any notices, payments or other communications required
by this Agreement shall be made as provided in Section 9.02 of the Merger
Agreement, except that such notices, payments or other communications shall be
addressed to each party's Director of Taxes.

            14. Governing Law. The principles and provisions of Section 9.07 of
the Merger Agreement shall apply to this Agreement.

            15. Entire Agreement. This Agreement, the Merger Agreement and the
agreements, Documents and other items referred to in Section 9.06 of the Merger
Agreement (a) constitute the entire agreement and supersede all prior agreements
and understandings, both written and oral, among the parties with respect to the
subject matter of this Agreement and (b) are not intended to confer upon any
person other than the parties hereto any rights or remedies. The

parties agree that to the extent the provisions of any other agreements executed
in connection with the Distribution or the Merger are inconsistent with the
provisions of this Agreement with respect to Tax Matters, the provisions of this
Agreement shall prevail.

            16. Counterparts. The principles and provisions of Section 9.05 of
the Merger Agreement shall apply to this Agreement.

            17. Severability. If any provision of this Agreement or the
application of any such provision to any person or circumstances shall be held
invalid, illegal or unenforceable in any respect by a court of competent
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision hereof.

            18. Headings. Headings of sections in this Agreement are inserted
for convenience of reference only and are not intended to be a part of or to
affect the meaning or interpretation of this Agreement.

            19. Definitions. Unless otherwise indicated, any capitalized term
not defined in this Agreement shall have the meaning given to such term by the
Merger Agreement.

            20. Enforcement; Consent to Jurisdiction. The provisions of Section
6.12 of the Post-Closing Covenants and Indemnification Agreement shall apply to
this Agreement.

            21. Interpretation. When a reference is made in this Agreement to a
Section, Schedule or Exhibit, such reference shall be to a Section, Schedule or
Exhibit of this Agreement unless otherwise indicated. The table of contents and
headings contained in this Agreement are for reference purposes only and shall
not affect in any way the meaning or interpretation of this Agreement. Whenever
the words "included", "includes" or "including" are used in this Agreement, they
shall be deemed to be followed by the words "without limitation". All accounting
terms not defined in this Agreement shall have the meanings determined by GAAP.

the quotient of (i)(A) the number of shares of Axion Common Stock outstanding
immediately prior to the Time of Distribution (including any shares of Axion
Common Stock issued in connection with the exercise of Axion Options in
connection with the consummation of the Merger) plus (B) the number of shares of

            WHEREAS, the execution and delivery of this Agreement by the parties
hereto is a condition to the obligations of the parties to the Merger Agreement
to consummate the Merger;

            WHEREAS, the parties to this Agreement, as a condition to their
obligations to consummate the Merger, have also entered into the Indemnification
Agreement and the Tax Matters Agreement to govern certain matters in connection
with the Contributions, the Distribution and the Merger; and

            WHEREAS, the escrow created pursuant hereto secures the continued
performance by the AHC Indemnifying Parties of each of the AHC Indemnifying
Party's respective obligations under Section 2.01 of the Indemnification
Agreement and Section 1 of the Tax Matters Agreement.

            NOW, THEREFORE, in consideration of the execution of the Merger
Agreement and the representations, warranties, covenants and agreements
contained in this Agreement, the parties agree as follows:

            1. Deposit of Escrowed Property. (a) Promptly upon the execution of
this Agreement, the following events shall occur:

            (i) The Exchange Agent, on behalf of the Former Axion Stockholders,
      shall deposit into escrow, and the Escrow Agent shall acknowledge receipt
      of, a number of shares of BMS Common Stock equal to $5,000,000 divided by
      the Average Value of BMS Common Stock, rounded to the nearest whole share,
      which amount shall be deemed to have been deposited by the Former Axion
      Stockholders on a pro rata basis from the shares of BMS Common Stock to be
      issued and delivered to each Former Axion Stockholder with respect to its
      shares of Axion Common Stock pursuant to Section 2.02(b) of the Merger
      Agreement, calculated based on the ratio of the number of shares of BMS
      Common Stock to be so issued and delivered to such Former Axion
      Stockholder with respect to its shares of Axion Common Stock to the
      aggregate number of shares of BMS Common Stock to be so issued to all the
      Former Axion Stockholders with respect to their shares of Axion Common
      Stock. Such shares together with any dividends and distributions with
      respect to such shares as set forth in Section 1(b) below and any income
      received from the investment thereof, as on

                                                                               4


      deposit or invested from time to time in accordance with the terms of this
      Agreement are hereinafter referred to as the "Escrowed Shares". Each
      Escrowed Share shall be registered in the name of AHC, as representative
      of the Former Axion Stockholders, endorsed in blank or accompanied by
      stock powers executed in blank, in proper form for transfer; and

            (ii) AHC shall deposit, or cause to be deposited, into escrow, and
      the Escrow Agent shall acknowledge receipt of, $5,000,000 in cash. Such
      cash, together with any income received thereon, as on deposit or invested
      from time to time in accordance with the terms of this Agreement, shall
      hereinafter be referred to as the "Escrowed Cash" (the Escrowed Shares and
      the Escrowed Cash together being the "Escrowed Property").

            (b) During the term of this Agreement, BMS shall, from time to time
and concurrently with the payment thereof, (i) deliver to the Escrow Agent for
deposit in accordance with the terms hereof, all non-taxable stock dividends and
other non-taxable distributions made with respect to the Escrowed Shares and
(ii) deliver to the Escrow Agent, who shall promptly distribute the same to the
Former Axion Stockholders, all cash distributions and other taxable
distributions (other than taxable distributions representing the proceeds of a
sale or acquisition of BMS or a substantial restructuring in connection with a
sale or acquisition of or by BMS) made with respect to the Escrowed Shares. All
such distributions to the Former Axion Stockholders pursuant to clause (ii)
above shall be allocated among them based on the ratio of the number of shares
of BMS Common Stock received by each Former Axion Stockholder at the Closing
with respect to such Former Axion Stockholder's shares of Axion Common Stock to
the aggregate number of shares of BMS Common Stock received by all Former Axion
Stockholders at the Closing with respect to all Former Axion Stockholders'
shares of Axion Common Stock. All dividends and all other distributions made on
or in respect of an Escrowed Share that are not required to be distributed to
the Former Axion Stockholders as provided pursuant to clause (ii) above, whether
resulting from a stock split, subdivision, combination or reclassification of
the outstanding capital stock of BMS or received in exchange for such Escrowed
Share or any part thereof, or in redemption thereof, or as a result of any
merger, consolidation, acquisition or other exchange of assets to which BMS may
be a party or otherwise, shall (together with the Escrowed

Share in respect of which such dividends or distributions were received) be and
become part of and be considered for purposes of Section 2(c) such Escrowed
Share. Any such dividend or distribution received that is so treated as part of
an Escrowed Share will be held by the Escrow Agent in the form in which such
dividend or distribution was received.

            If any dividends or distributions made on or in respect of an
Escrowed Share that are not required to be distributed to the Former Axion
Stockholders as provided pursuant to clause (ii) above are received by any
Former Axion Stockholder prior to the release of such Escrowed Share to such
Former Axion Stockholder in accordance with the provisions of this Agreement,
such dividends or distributions shall not be commingled by such Former Axion
Stockholder with any of its other funds or property but shall be held separate
and apart therefrom, shall be held in trust for the benefit of the Escrow Agent
and shall be forthwith delivered to the Escrow Agent in the same form as so
received (with any necessary endorsement).

            (c) BMS and each AHC Indemnifying Party acknowledge and agree that,
to the extent and so long as any of the Escrowed Property is held by the Escrow
Agent hereunder, BMS shall have, as of and from the date such Escrowed Property
is received by the Escrow Agent, a perfected first priority security interest in
such Escrowed Property to secure the payment of the amount, if any, payable by
an AHC Indemnifying Party pursuant to Section 2.01 of the Indemnification
Agreement and Section 1 of the Tax Matters Agreement. In connection therewith,
each AHC Indemnifying Party expressly agrees (i) that the Escrow Agent is acting
solely as BMS's agent to the extent necessary to perfect BMS's first priority
security interest in the Escrowed Property and (ii) to execute and deliver such
instruments as BMS may from time to time reasonably request for the purpose of
evidencing and perfecting such security interest. In the event that any cash
portion of the Escrowed Shares is invested pursuant to Section 5, the Escrow
Agent shall take all actions necessary, including, but not limited to,
appropriate identification on the Escrow Agent's books and records, to ensure
that all such investments are deemed held by the Escrow Agent as BMS's agent for
the purpose of perfecting BMS's first-priority security interest therein.

            (d) Each of BMS and each of the AHC Indemnifying Parties agree that
the Escrowed Shares shall be voted by the

Escrow Agent with respect to all matters as to which the holders of BMS Common
Stock are entitled to vote in accordance with written instructions from AHC as
the representative of the Former Axion Stockholders. AHC hereby agrees that if
any Former Axion Stockholder provides AHC with written directions as to how to
vote the Escrowed Shares with respect to any matter, AHC shall instruct the
Escrow Agent to vote such number of Escrowed Shares as are beneficially held for
such Former Axion Stockholder (calculated based on the ratio of the number of
shares of BMS Common Stock received by such Former Axion Stockholder at the
Closing with respect to such Former Axion Stockholder's shares of Axion Common
Stock to the aggregate number of shares of BMS Common Stock received by all
Former Axion Stockholders at the Closing with respect to all Former Axion
Stockholders' shares of Axion Common Stock) as so directed by such Former Axion
Stockholder, and if no such directions are received with respect to particular
Escrowed Shares on any matter for which such Escrowed Shares may be voted, AHC
shall direct the Escrow Agent to abstain from voting such Escrowed Shares with
respect to such matter.

            2. Disposition of Escrowed Property. (a) The Escrow Agent shall hold
the Escrowed Property in its possession until authorized in writing hereunder to
deliver such Escrowed Property as follows:

            (i) At any time on or prior to the Escrowed Cash Termination Date
      (as defined in Section 10), BMS may deliver a Certificate (as defined in
      Section 8) to the Escrow Agent requesting delivery of Escrowed Property to
      BMS, and the Escrow Agent shall deliver the Escrowed Property to BMS to
      the extent and at the time provided in accordance with Section 3 hereof;
      provided, however, that no distribution of Escrowed Property shall be made
      in respect of any Indemnified Obligation (as defined in Section 3(a))
      related to a liability for Taxes for which a BMS Indemnified Party (as
      defined in Section 3(a)) is indemnified pursuant to Section 1 of the Tax
      Matters Agreement unless and until such time as such liability for Taxes
      shall be deemed liquidated and therefore payable in accordance with the
      provisions of Section 9 of the Tax Matters Agreement, (ii) after the
      Escrowed Shares Termination Date (as defined in Section 10 below), no
      Escrowed Shares shall be released to BMS except with respect to an
      Escrowed Shares Pending Claim (as defined in Section 2(a)(ii) below)) and
      (iii) after the Second Anniversary Date (as defined

                                                                               7


      in Section 2(a)(iii) below), Second Anniversary Cash shall be released to
      BMS only with respect to Second Anniversary Pending Claims (as defined in
      Section 2(a)(iii) below). For purposes of the foregoing, the amount of
      Second Anniversary Cash as of any date shall equal the excess, if any, of
      the amount of Escrowed Cash on deposit with the Escrow Agent on such date
      over the amount specified in clause (A) of the definition of "Retained
      Escrow Amount (as defined in Section 2(a)(iii) below) calculated as of
      such date.

            (ii) Immediately following the Escrowed Shares Termination Date, if
      either (A) both BMS and AHC deliver a Certificate to the Escrow Agent or
      (B) the Escrow Agent (I) receives a Certificate from AHC, (II) delivers a
      copy of such Certificate to BMS and (III) does not, within 15 business
      days following delivery of such Certificate to BMS, receive written notice
      from BMS objecting to such Certificate given by AHC, the Escrow Agent
      shall deliver to AHC as the representative of the Former Axion
      Stockholders such number of Escrowed Shares (rounded to the nearest whole
      share) that equals, when multiplied by the Average Value of BMS Common
      Stock, the excess, if any, of (x) the number of Escrowed Shares on deposit
      with the Escrow Agent on the Escrowed Shares Termination Date multiplied
      by the Average Value of BMS Common Stock over (y) the amount of any unpaid
      Escrowed Shares Pending Claims (as defined below) on the Escrowed Shares
      Termination Date. Thereafter, if as of the last day of any fiscal quarter
      following the Escrowed Shares Termination Date, Escrowed Shares remain on
      deposit with the Escrow Agent, and either (A) both BMS and AHC deliver a
      Certificate to the Escrow Agent or (B) the Escrow Agent (I) receives a
      Certificate from AHC, (II) delivers a copy of such Certificate to BMS and
      (III) does not, within 15 business days following delivery of such
      Certificate to BMS, receive written notice from BMS objecting to such
      Certificate given by AHC, the Escrow Agent shall deliver to AHC as the
      representative of the Former Axion Stockholders the number of Escrowed
      Shares that equals, when multiplied by the Average Value of BMS Common
      Stock, the excess, if any, of (x) the number of Escrowed Shares on deposit
      with the Escrow Agent on the last day of such fiscal quarter multiplied by
      the Average Value of BMS Common Stock over (y) the amount of any unpaid
      Escrowed Shares Pending Claims on the last day of such fiscal quarter.

      "Escrowed Shares Pending Claims" shall mean all the Pending Claims (as
      defined in Section 4 below) existing on the Escrowed Shares Termination
      Date. The amount of any Escrowed Shares Pending Claim on any date shall be
      determined in accordance with the provisions of Section 4.

            (iii) Immediately following the second anniversary of the date of
      this Agreement (the "Second Anniversary Date"), if either (A) both BMS and
      AHC jointly deliver a Certificate to the Escrow Agent or (B) the Escrow
      Agent (I) receives a Certificate from AHC, (II) delivers a copy of such
      Certificate to BMS and (III) does not, within 15 business days following
      delivery of such Certificate to BMS, receive written notice from BMS
      objecting to the Certificate given by AHC, the Escrow Agent shall deliver
      to AHC an amount in cash equal to the excess, if any, of Escrowed Cash on
      deposit with the Escrow Agent as of the Second Anniversary Date over the
      Retained Escrow Amount on the Second Anniversary Date. Thereafter, if as
      of the last day of any fiscal quarter following the Second Anniversary
      Date, Escrowed Cash remains on deposit with the Escrow Agent and either
      (A) both BMS and AHC deliver a Certificate to the Escrow Agent or (B) the
      Escrow Agent (I) receives a Certificate from AHC, (II) delivers a copy of
      such Certificate to BMS and (III) does not, within 15 business days
      following delivery of such Certificate to BMS, receive written notice from
      BMS objecting to such Certificate given by AHC, the Escrow Agent shall
      deliver to AHC an amount in cash equal to the excess, if any, of Escrowed
      Cash on deposit with the Escrow Agent as of the last day of such fiscal
      quarter over the Retained Escrow Amount as of the last day of such fiscal
      quarter. "Retained Escrow Amount" shall mean, as of any date, the sum of
      (A) an amount, if any, equal to the excess of $1,000,000 over (i) the
      aggregate amount, if any, of Escrowed Cash that shall have been released
      during the period from the Second Anniversary Date to such date in respect
      of any Pending Claim that was not an existing Pending Claim at any time on
      or prior to the Second Anniversary Date and (ii) the aggregate amount, if
      any, released to AHC pursuant to Section 2(a)(iv) below from and after the
      Escrowed Cash Termination Date and (B) the amount of any unpaid Second
      Anniversary Pending Claims (as defined below) on such date. "Second
      Anniversary Pending Claims" shall mean all the Pending

      Claims existing on the Second Anniversary Date (and, for the avoidance of
      doubt, shall include all Escrowed Shares Pending Claims existing on such
      date). The amount of any Second Anniversary Pending Claim on any date
      shall be determined as provided in Section 4, provided that, for all
      purposes of this Section 2.01(a)(iii), the amount of unpaid Second
      Anniversary Pending Claims on the last day of any fiscal quarter ending
      after the Second Anniversary Date shall be reduced by an amount equal to
      (x) the number of Escrowed Shares on deposit with the Escrow Agent on the
      last day of such fiscal quarter (such number to be determined based on the
      assumption that any Escrowed Shares that are to be delivered to AHC as the
      representative of the Former AHC Stockholders in respect of the last day
      of such fiscal quarter as provided in the second sentence of Section
      2(a)(ii) above shall have been so delivered and shall not be on deposit
      with the Escrow Agent on the last day of such fiscal quarter), if any,
      multiplied by (y) the Average Value of BMS Common Stock.

            (iv) Immediately following the Escrowed Cash Termination Date, if
      either (A) both BMS and AHC deliver a Certificate to the Escrow Agent or
      (B) the Escrow Agent (I) receives a Certificate from AHC, (II) delivers a
      copy of such Certificate to BMS and (III) does not, within 15 business
      days following delivery of such Certificate to BMS, receive written notice
      from BMS objecting to such Certificate given by AHC, the Escrow Agent
      shall deliver to AHC an amount equal to the excess, if any, of Escrowed
      Cash on deposit with the Escrow Agent as of the Escrowed Cash Termination
      Date (calculated as provided below) over an amount equal to any unpaid
      Final Pending Claims (as defined below) on the Escrowed Cash Termination
      Date. Thereafter, if as of the last day of any fiscal quarter following
      the Escrowed Cash Termination Date Escrowed Cash remains on deposit with
      the Escrow Agent and either (A) both BMS and AHC deliver a Certificate to
      the Escrow Agent or (B) the Escrow Agent (I) receives a Certificate from
      AHC, (II) delivers a copy of such Certificate to BMS and (III) does not,
      within 15 business days following delivery of such Certificate to BMS,
      receive written notice from BMS objecting to such Certificate given by
      AHC, the Escrow Agent shall deliver to AHC an amount equal to the excess,
      if any, of Escrowed Cash on deposit with the Escrow Agent as of

      the last day of such fiscal quarter (calculated as provided below) over an
      amount equal to any unpaid Final Pending Claims on the last day of such
      fiscal quarter. For purposes of this Section 2.01(a)(iv), the amount of
      any Escrowed Cash on deposit with the Escrow Agent shall be calculating by
      treating the amount, if any, of Escrowed Cash that is to be delivered to
      AHC pursuant to Section 2.01(a)(iii) on such date as having been so
      delivered and as not being on deposit with the Escrow Agent on such date.
      "Final Pending Claims" shall mean all Pending Claims existing on the
      Escrowed Cash Termination Date (and, for the avoidance of doubt, shall
      include all Escrowed Shares Pending Claims and Second Anniversary Pending
      Claims existing on such date). The amount of any Final Pending Claim on
      any date shall be determined as provided in Section 4, provided that, for
      purposes of this Section 2.01(a)(iv) the amount of unpaid Final Pending
      Claims on the last day of any fiscal quarter ending after the Escrowed
      Cash Termination Date shall be reduced by an amount equal to (x) the
      number of Escrowed Shares on deposit with the Escrow Agent on the last day
      of such fiscal quarter (such number to be determined based on the
      assumption that any Escrowed Shares that are to be delivered to AHC as the
      representative of the Former AHC Stockholders in respect of the last day
      of such fiscal quarter is provided in the second sentence of Section
      2(a)(ii) above shall have been so delivered and shall not be on deposit
      with the Escrow Agent on the last day of such fiscal quarter), if any,
      multiplied by (y) the Average Value of BMS Common Stock.

            (v) Either BMS or AHC may deliver to the Escrow Agent a Certificate
      accompanied by a final and nonappealable award or order of a court of
      competent jurisdiction (a "Court Order") with respect to the payment of
      all or any portion of the Escrowed Property requesting delivery of
      Escrowed Property to BMS, AHC or such other person(s) as may be specified
      in such award or order. Such Certificate also shall be accompanied by an
      opinion of outside counsel to the effect that the applicable court award
      or order is final and nonappealable. In either such case, the Escrow Agent
      shall deliver all or a portion of the Escrowed Property to BMS or AHC, as
      the case may be, in the amount specified in the Court Order.

            (vi) If AHC shall have delivered to the Escrow Agent and BMS at any
      time within 30 days before or after the due date (including extensions)
      for payment by AHC of its final Federal income tax liability for a taxable
      year (or, if later, 30 days after the Escrow Agent supplies all
      information relating to the income realized with respect to the Escrowed
      Cash necessary to prepare the Certificate referred to in this Section
      2.01(a)(vi) a Certificate setting forth the amount of Federal and State of
      California income tax due from AHC with respect to any taxable income
      realized with respect to the Escrowed Cash for such taxable year (based on
      the assumption that AHC is, with respect to such income, subject to
      Federal and State of California income tax at the highest regular marginal
      tax rate applicable to corporations for such year), and the accuracy and
      completeness of such Certificate shall be certified by Ernst & Young LLP,
      or such other nationally recognized accounting firm chosen by AHC and
      reasonably satisfactory to BMS, then the Escrow Agent shall pay to AHC in
      cash the amount set forth in such Certificate no more than fifteen days
      after receipt of such Certificate. The Escrow Agent shall use commercially
      reasonable efforts to supply to AHC the tax information referred to above
      prior to the start of the 60-day period referred to above.

            (b) All distributions hereunder that are not the subject of a
dispute shall be made no later than 20 days from receipt of a Certificate and
shall be made from the Escrowed Shares and/or the Escrowed Cash, as the case may
be, in accordance with Section 2(a) above. Distributions made to BMS pursuant to
Section 2(a)(i) above shall first be made from any Escrowed Shares on deposit
and then, to the extent so required, from any Escrowed Cash. Distributions made
pursuant to Section 2(a)(vi) shall be deemed to have been made from the Escrowed
Cash.

            (c) In the case of any distribution of Escrowed Shares pursuant to
this Agreement, each Escrowed Share so distributed shall be valued at a price
per share equal to the Average Value of BMS Common Stock and all such
distributions shall be rounded to the nearest whole share. All Escrowed Shares
distributed to AHC pursuant to this Agreement shall be distributed by AHC pro
rata to the Former Axion Stockholders based on the ratio of the number of shares
of BMS Common Stock received by such Former Axion Stockholder at the Closing
with respect to such Former Axion

                                                                              12


Stockholder's shares of Axion Common Stock to the aggregate number of shares of
BMS Common Stock received by all Former Axion Stockholders at the Closing with
respect to all Former Axion Stockholders' shares of Axion Common Stock.

            (d) Upon any distribution of Escrowed Property pursuant to this
Agreement, BMS's security interest in the Escrowed Property to the extent of
such distribution shall be, and shall be deemed to be, released and discharged
as of and from the moment of such release from escrow.

            (e) In the case of each of Sections 2(a)(ii), 2(a)(iii) and
2(a)(iv), if BMS delivers to the Escrow Agent written notice objecting to any
Certificate from AHC requesting the release of the Escrowed Property, such
notice shall specify the disputed amount of such release request and the amount
not in dispute. Notwithstanding anything to the contrary set forth in this
Section 2, the Escrow Agent shall be authorized to deliver to AHC (as the
representative of the Former Axion Stockholders in the case of any delivery of
Escrowed Shares) the amount of such release request not in dispute, subject to
and in accordance with the applicable provision of Section 2(b) hereof.

            3. Distributions for Indemnified Obligations. (a) At any time on or
prior to the Escrowed Cash Termination Date, BMS may deliver to the Escrow Agent
a Certificate (i) stating that (A) a BMS Indemnified Party has incurred an
Indemnifiable Loss against which such BMS Indemnified Party is entitled to be
indemnified pursuant to Section 2.01 of the Indemnification Agreement or (B) a
BMS Indemnified Party is liable for Taxes against which such BMS Indemnified
Party is entitled to be indemnified pursuant to Section 1 of the Tax Matters
Agreement (each, an "Indemnified Obligation"), (ii) stating the aggregate amount
of such Indemnified Obligation (or, in the case of an unliquidated Indemnified
Obligation, a good faith and reasonable estimate thereof) and (iii) specifying
in reasonable detail the nature of each item included in such Indemnified
Obligation (an "Indemnification Item"), the amount thereof and the date on which
such Indemnification Item was paid or incurred; provided, however, that BMS may
not deliver to the Escrow Agent a Certificate stating that a BMS Indemnified
Party is liable for Taxes against which such BMS Indemnified Party is entitled
to be indemnified pursuant to Section 1 of the Tax Matters Agreement unless and
until any of the following shall have occurred: (a) a Tax Return shall have been
filed as provided in the Tax Matters

Agreement showing such Taxes to be due and payable and the full amount of such
Taxes shall not have been paid at the time such Tax Return was filed; (b) a
Taxing Authority shall have asserted in writing or determined that there is a
deficiency with respect to such Taxes; (c) except with respect to any claim for
indemnification for Taxes relating in any respect to (i) the Contributions, the
Distribution, the Merger or any of the other Transactions, (ii) any sales or use
Taxes, other than (A) Pre-JV Sales Taxes, (B) JV Sales Taxes and (C) any
liability of any BMS Indemnified Party with respect to unpaid sales and use
taxes on rentals of OPUS Station machines, and (iii) the distribution of the
stock of OnCare, Inc. by Axion, BMS shall have received an opinion of a
nationally recognized accounting firm or law firm reasonably acceptable to AHC
that it is more likely than not that such Taxes will be properly payable; or (d)
there shall have been a "determination" (as defined in Section 1313 of the Code)
that such Taxes are due and payable. For purposes of this Agreement, "BMS
Indemnified Party" shall have the meaning assigned to such term in the
Indemnification Agreement or the Tax Matters Agreement, as applicable. Any
Certificate delivered pursuant to this Section with respect to any unliquidated
Indemnified Obligation may be supplemented by a later Certificate specifying in
greater detail the items set forth therein. Upon delivery of any such
Certificate, the Escrow Agent shall, within five days of receipt thereof,
deliver a written notice together with a copy of such Certificate to AHC.

            (b) If AHC objects to the Indemnified Obligation specified in such
Certificate, AHC shall, within 10 business days after delivery of the written
notice containing a copy of any such Certificate, deliver to the Escrow Agent a
certificate (a "Reply Certificate"), (i) specifying each such amount to which
AHC objects and (ii) specifying in reasonable detail the nature and basis for
each such objection. Within five business days of delivery to the Escrow Agent
of a Reply Certificate, the Escrow Agent shall deliver a copy of such Reply
Certificate to BMS. BMS and AHC shall negotiate in good faith for a period of 30
days after delivery of such Reply Certificate to BMS to reach a written
resolution of any matters raised in a Reply Certificate.

            (c) If no Reply Certificate is delivered with respect to any
Certificate or any Indemnification Item contained therein, then AHC shall be
deemed to have

acknowledged BMS's right to receive any amount or amounts specified in such
Certificate (or the undisputed portion thereof), and the Escrow Agent shall
transfer to BMS, Escrowed Property in an amount equal to the undisputed amount
claimed in such Certificate (plus interest at a rate per annum equal to the
prime rate announced from time to time by The Chase Manhattan Bank on such
amount from the later of (i) the date of such Certificate and (ii) the date such
indemnified amount was actually incurred by the applicable Indemnified Party),
all in accordance with the procedures set forth in Section 2(b).

            (d) If the Escrow Agent receives a Reply Certificate in a timely
manner, the disputed amount requested for reimbursement pursuant to the
applicable Certificate shall be held by the Escrow Agent and shall not be
released to BMS except in accordance with either (i) written instructions signed
by each of an authorized officer of BMS and AHC or (ii) the final nonappealable
judgment of a court having jurisdiction over the matters relating to the claim
by the applicable Indemnified Party for indemnification from AHC accompanied by
an opinion of outside counsel to the effect that the applicable judgment is
final and nonappealable, at which date the portion of the amount due to such
Indemnified Party determined pursuant to (i) or (ii) in this paragraph 3(d)
shall promptly be paid to BMS in accordance with the procedures set forth in
Section 2(b).

            (e) The parties hereto agree that the payment of Indemnified
Obligations contemplated by this Section is not, and shall not be deemed to be,
a waiver of any right, claim or amount to which BMS may be entitled under the
Indemnification Agreement, the Tax Matters Agreement or otherwise, including any
claim relating to an Indemnified Obligation, to the extent that the amount paid
to BMS pursuant hereto is insufficient to satisfy the entire amount of any such
Indemnified Obligation.

            (f) Notwithstanding anything to the contrary set forth in Section 2
or Section 3 hereof, upon receipt of written notice from the Escrow Agent
containing a copy of a Certificate relating to an Indemnified Obligation the
final amount of which shall have been liquidated, AHC may elect to pay to BMS
such amount in cash in lieu of payment being made from the Escrowed Property if
AHC, within ten business days after delivery of the written notice containing a
copy of the Certificate, shall have delivered to BMS and the Escrow

                                                                              15


Agent a written notice stating its election to make such cash payment and,
thereafter, shall have made such cash payment to BMS on the earliest date that a
payment of Escrowed Property would otherwise be made hereunder with respect to
such Indemnified Obligation; provided, however, that such Indemnified Obligation
shall constitute a Pending Claim for all purposes of this Agreement until the
time the full amount of such cash payment is actually received by BMS.

            4. Pending Claims. (a) For purposes of this Agreement, "Pending
Claims" shall mean, at any time, (a) all indemnification claims with respect to
which a Certificate shall have been delivered at or prior to such time with
respect to which the final amount of such claims shall have been liquidated and
which shall not have been paid in full at such time whether because the payment
of such amount is in dispute or otherwise and (b) all indemnification claims
with respect to which a Certificate shall have been delivered and with respect
to which the final amount of such claim shall not have been liquidated.

            (b) The amount of any Pending Claim as of any date shall be equal to
BMS's reasonable estimate of such amount. If any Pending Claim shall exist on
the last day of any fiscal quarter during the term of this Agreement, not later
than 10 business days after the last day of such fiscal quarter, BMS shall
deliver to the Escrow Agent a Certificate (a "Quarterly Certificate") setting
forth BMS's reasonable estimate of the amount of each then existing Pending
Claim as of the last day of such fiscal quarter, provided that, if BMS shall not
deliver a Quarterly Certificate in respect of any fiscal quarter or shall not
include in such Quarterly Certificate all Pending Claims existing on the last
day of such fiscal quarter, the amount of each Pending Claim (or the amount of
any Pending Claim not included in such Quarterly Certificate, as applicable)
shall be the amount of each such Pending Claim set forth in the most recent
Certificate (including any Quarterly Certificate) delivered by BMS to the Escrow
Agent in respect of the amount of such Pending Claim, provided further that
failure of BMS to deliver a Quarterly Certificate in respect of any fiscal
quarter shall not affect in any manner the obligations of the AHC Indemnifying
Parties hereunder or under the Indemnification Agreement or the Tax Matters
Agreement or the rights of BMS or any other BMS Indemnified Party hereunder or
thereunder.

            (c) If AHC reasonably objects to the amount of any Pending Claim
specified in any Certificate delivered pursuant to this Section 4, AHC shall,
within 10 business days after delivery of such Certificate, deliver to the
Escrow Agent a Certificate (the "Amount Certificate"), (i) specifying each such
amount to which AHC reasonably objects and (ii) specifying in reasonable detail
the nature and basis for each such objection. Within five business days of
delivery to the Escrow Agent of the Amount Certificate, the Escrow Agent shall
deliver a copy of such Amount Certificate to BMS. BMS and AHC shall negotiate in
good faith for a period of 30 days after delivery by the Escrow Agent to BMS of
such Amount Certificate to reach a written resolution of any matters raised in
the Amount Certificate and, if such matters are not resolved within a 30-day
period, either party may bring an action to resolve such dispute as provided in
Section 17. Notwithstanding the foregoing, the amount of any Pending Claim with
respect to which an Amount Certificate shall have been delivered shall be for
all purposes of this Agreement the amount reasonably determined by BMS as
provided in Section 4(b) above unless and until such time as the Escrow Agent
either (a) receives written instructions signed by an authorized officer of each
of BMS and AHC adjusting the amount of such Pending Claim or (b) the final
nonappealable judgment of a court having jurisdiction over the matters relating
to the claim by the applicable BMS Indemnified Party for indemnification from
any AHC Indemnifying Party adjusting the amount of such Pending Claim
accompanied by an opinion of outside counsel to the effect that the applicable
judgment is final and nonappealable, at which date, in the event that the Escrow
Agent shall have received an Amount Certificate from AHC within the time frame
set forth above, the amount of the Pending Claim for all purposes of this
Agreement shall be adjusted to the amount determined pursuant to clauses (a) or
(b) of this sentence.

            5. Investments; Disposition of Income. The Escrow Agent agrees that
it shall invest the Escrowed Cash and the cash portion of the Escrowed Shares,
in (i) direct obligations of, or obligations fully guaranteed by, the United
States of America or any agency thereof having a maturity of not more than 180
days, (ii) certificates of deposit of the Escrow Agent or any commercial bank in
the United States of America having total capital surplus and undivided profits
in excess of $500,000,000 and (iii) securities approved jointly in writing by
BMS and AHC, all as the parties hereto, from time to time, shall jointly

instruct the Escrow Agent to do in writing. Any income received by the Escrow
Agent from investments of the Escrowed Property pursuant to this Section 5 shall
be added to the Escrowed Property and distributed as provided in this Agreement.
Upon liquidation of an investment of the Escrowed Property, the Escrowed
Property shall be deposited into a non-interest bearing account pending receipt
of written investment instructions from BMS and AHC as provided in this Section
5 or Certificate or other disbursement instruction as provided in Section 2.

            6. Concerning the Escrow Agent. (a) The Escrow Agent shall not be
required to invest any funds held hereunder except as directed pursuant to
Section 5. Uninvested funds held hereunder shall not earn or accrue interest.

            (b) This Agreement expressly sets forth all the duties of the Escrow
Agent with respect to any and all matters pertinent hereto. No implied duties or
obligations shall be read into this agreement against the Escrow Agent. The
Escrow Agent shall not be bound by the provisions of any agreement among the
other parties hereto except this Agreement. The Escrow Agent's duties shall be
ministerial in nature.

            (c) The Escrow Agent shall not be liable, except for its own gross
negligence or wilful misconduct, and, except with respect to claims based upon
such gross negligence or wilful misconduct that are successfully asserted
against the Escrow Agent, the other parties hereto shall jointly and severally
indemnify and hold harmless the Escrow Agent (and any successor Escrow Agent)
from and against any and all losses, liabilities, claims, actions, taxes,
damages and expenses, including, without limitation, reasonable attorneys' fees
and disbursements, arising out of or in connection with this Agreement
including, without limitation, the legal costs and expenses of defending itself
against any claim or liability in connection with its performance hereunder. The
Escrow Agent further agrees that all Escrowed Property shall be available for
withdrawal on not less than two business days' prior written notice.

            (d) The Escrow Agent shall be entitled to rely upon any order,

correctness of any fact stated therein or the propriety or

                                                                              18

instrument or signature believed by it to be genuine and may assume that any
person purporting to give notice or receipt or advice or make any statement or
execute any document in connection with the provisions hereof has been duly
authorized to do so.

            (e) The Escrow Agent may act pursuant to the advice of counsel with
respect to any matter relating to this Agreement and shall not be liable for any
action taken or omitted in accordance with such advice.

            (f) The Escrow Agent does not have any interest in the Escrowed
Property deposited hereunder but is serving as escrow agent only and having only
possession thereof. The parties agree that any income realized with respect to
the Escrowed Cash shall be treated for all purposes as income of AHC, and any
income realized with respect to the Escrowed Shares shall be treated for all
purposes as income of the Former Axion Stockholders. Any payments of income from
this Agreement shall be subject to withholding regulations then in force with
respect to United States taxes. The parties hereto will provide the Escrow Agent
with appropriate W-9 forms for tax identification, number certification, or
nonresident alien certifications. This paragraph and paragraph (c) shall survive
notwithstanding any termination of this Agreement or the resignation of the
Escrow Agent.

            (g) The Escrow Agent makes no representation as to the validity,
value, genuineness or the collectibility of any security or other documents or
instrument held by or delivered to it.

            (h) The Escrow Agent shall not be called upon to advise any party as
to the wisdom in selling or retaining or taking or refraining from any action
with respect to any securities or other property deposited hereunder.

            (i) The Escrow Agent (and any successor Escrow Agent) may at any
time resign as such by delivering the Escrowed Property, subject to subparagraph
(1) below, to any successor Escrow Agent jointly designated by the other parties
hereto in writing, or to any court of competent jurisdiction, whereupon the
Escrow Agent shall be discharged of and from any and all further obligations
arising in connection with this Agreement. The resignation of the Escrow Agent
will take effect on the earlier of (i) the

appointment of a successor (including a court of competent jurisdiction) or (ii)
the day which is 30 days after the date of delivery of its written notice of
resignation to the other parties hereto. If at that time the Escrow Agent has
not received a designation of a successor Escrow Agent, the Escrow Agent's sole
responsibility after that time shall be to safekeep the Escrowed Property until
receipt of a designation of successor Escrow Agent or a joint written
disposition instruction by the other parties hereto or a final and nonappealable
order of a court of competent jurisdiction.

            (j) In the event of any disagreement between the other parties
hereto resulting in adverse claims or demands being made in connection with the
Escrowed Property, or in the event that the Escrow Agent in good faith is in
doubt as to what action it should take hereunder, the Escrow Agent shall be
entitled to retain the Escrowed Property until the Escrow Agent shall have
received (i) a final nonappealable order of a court of competent jurisdiction
directing delivery of the Escrowed Property or (ii) a written agreement executed
by the other parties hereto directing delivery of the Escrowed Property, in
which event the Escrow Agent shall disburse the Escrowed Property in accordance
with such order or agreement. Any court order referred to in (i) above shall be
accompanied by a legal opinion of outside counsel satisfactory to the Escrow
Agent to the effect that said court order is final and nonappealable. The Escrow
Agent shall act on such court order and legal opinions without further question.

            (k) The Escrow Agent shall be paid $[ ] annually. All fees shall be
paid in United States currency and payable in the United States at the office of
the Escrow Agent. It is understood that the Escrow Agent's fees may be adjusted
from time to time to conform with its then current guidelines. Such fees shall
be paid in equal proportions by BMS, on the one hand, and AHC, on the other
hand.

            (l) The Escrow Agent shall not incur any liability for following the
instructions herein contained or expressly provided for, or written instruction
given by the parties hereto.

only to the extent that it is indemnified to its satisfaction against the cost
and expense of such defense or initiation.

     Delaware General Corporation Law Section 262 APPRAISAL RIGHTS. (a) Any
stockholder of a corporation of this State who holds shares of stock on the date
of the making of a demand pursuant to subsection (d) of this section with
respect to such shares, who continuously holds such shares through the effective
date of the merger or consolidation, who has otherwise complied with subsection
(d) of this section and who has neither voted in favor of the merger or
consolidation nor consented thereto in writing pursuant to ss. 228 of this title
shall be entitled to an appraisal by the Court of Chancery of the fair value of
his shares of stock under the circumstances described in subsections (b) and (c)
of this section. As used in this section, the word "stockholder" means a holder
of record of stock in a stock corporation and also a member of record of a
nonstock corporation; the words "stock" and "share" mean and include what is
ordinarily meant by those words and also membership or membership interest of a
member of a nonstock corporation; and the words "depository receipt" mean a
receipt or other instrument issued by a depository representing an interest in
one or more shares, or fractions thereof, solely of stock of a corporation,
which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to ss. 251, 252, 254, 257, 258, 263 or 264 of this title:

     (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the holders of the surviving corporation as
provided in subsections (f) or (g) of ss. 251 of this title.

     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to ss.ss. 251, 252,

254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

          a. Shares of stock of the corporation surviving or resulting from such
merger or consolidation, or depository receipts in respect thereof;

          b. Shares of stock of any other corporation, or depository receipts in
respect thereof, which shares of stock or depository receipts at the effective
date of the merger or consolidation will be either listed on a national
securities exchange or designated as a national market system security on an
interdealer quotation system by the National Association of Securities Dealers,
Inc. or held of record by more than 2,000 holders;

          c. Cash in lieu of fractional shares or fractional depository receipts
described in the foregoing subparagraphs a. and b. of this paragraph; or

          d. Any combination of the shares of stock, depository receipts and
cash in lieu of fractional shares or fractional depository receipts and cash in
lieu of fractional shares or fractional depository receipts described in the
foregoing subparagraphs a., b. and c. of this paragraph.

     (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under ss. 253 of this title is not owned by the
parent corporation immediately prior to the merger, appraisal rights shall be
available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as practicable.

     (d) Appraisal rights shall be perfected as follows:

     (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the

                                                                               3


corporation, not less than 20 days prior to the meeting, shall notify each of
its stockholders who was such on the record date for such meeting with respect
to shares for which appraisal rights are available pursuant to subsections (b)
or (c) hereof that appraisal rights are available for any or all of the shares
of the constituent corporations, and shall include in such notice a copy of this
section. Each stockholder electing to demand the appraisal of his shares shall
deliver to the corporation, before the taking of the vote on the merger or
consolidation, a written demand for appraisal of his shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
his shares. A proxy or vote against the merger or consolidation shall not
constitute such a demand. A stockholder electing to take such action must do so
by a separate written demand as herein provided. Within 10 days after the
effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or

     (2) If the merger or consolidation was approved pursuant to ss. 228 or 258
of this title, the surviving or resulting corporation, either before the
effective date of the merger or consolidation or within 10 days thereafter,
shall notify each of the stockholders entitled to appraisal rights of the
effective date of the merger or consolidation and that appraisal rights are
available for any or all of the shares of the constituent corporation, and shall
include in such notice a copy of this section. The notice shall be sent by
certified or registered mail, return receipt requested, addressed to the
stockholder at his address as it appears on the records of the corporation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of the notice, demand in writing from the surviving or resulting
corporation the appraisal of his shares. Such demand will be sufficient if it
reasonably informs the corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of his shares.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding

                                                                               4


the foregoing, at any time within 60 days after the effective date of the merger
or consolidation, any stockholder shall have the right to withdraw his demand
for appraisal and to accept the terms offered upon the merger or consolidation.
Within 120 days after the effective date of the merger or consolidation, any
stockholder who has complied with the requirements of subsections (a) and (d)
hereof, upon written request, shall be entitled to receive from the corporation
surviving the merger or resulting from the consolidation a statement setting
forth the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of shares not voted in favor of the merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after his written request for such a
statement is received by the surviving or resulting corporation or within 10
days after expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit

                                                                               5


their certificates of stock to the Register in Chancery for notation thereon of
the pendency of the appraisal proceedings; and if any stockholder fails to
comply with such direction, the Court may dismiss the proceedings as to such
stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the

                                                                               6


fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which his prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                                   AXION HEALTHCARE INC.
                                   AND THE DISTRIBUTION

                                       INTRODUCTION
   

               This Information  Statement is being furnished to stockholders of
Axion  Inc.,  a  Delaware   corporation   ("Axion"),   in  connection  with  the
contemplated pro rata distribution (the "Distribution") to Axion stockholders of
shares of Series A Preferred  Stock,  par value $.0001 per share ("AHC Preferred
Stock"),  of Axion  HealthCare  Inc.,  a Delaware  corporation  and wholly owned
subsidiary of Axion ("AHC"). The holders of shares of common stock of Axion, par
value $.001 per share  ("Axion  Common  Stock"),  will  receive one share of AHC
Preferred  Stock with  respect to each share of Axion  Common Stock held by such
holder on the record date for the Distribution (the "Distribution  Record Date")
and the  holders of shares of Axion  Preferred  Stock (as defined  herein)  will
receive  one share of AHC  Preferred  Stock with  respect to each share of Axion
Preferred  Stock  held by such  holder  on the  Distribution  Record  Date.  The
Distribution will result in 100% of the then outstanding shares of AHC Preferred
Stock being distributed to Axion stockholders on a share-for-share basis.

               The  Distribution  is being effected by Axion in connection  with
the acquisition by Bristol-Myers Squibb Company, a Delaware corporation ("BMS"),
of Axion and its oncology drug  distribution-related  business interests,  which
consist  of:  (i)  Oncology   Therapeutics  Network   Corporation,   a  Delaware
corporation  and wholly owned  subsidiary of Axion  ("OTNC"),  including  OTNC's
interest in the Oncology  Therapeutics  Network Joint Venture,  L.P., a Delaware
limited  partnership (the  "Partnership" or "OTN"), and (ii) OPUS Health Systems
Inc., a Delaware  corporation  and wholly owned  subsidiary  of Axion  ("OPUS"),
which at the  Effective  Time (as defined  herein)  will  contain  only the OPUS
Station  automated drug dispensing and inventory  tracking systems business (the
"OPUS  Station  Business"),  including  in each  case  the  assets  and  certain
liabilities  related thereto (the "Retained  Business").  The acquisition by BMS
will be effected by a merger  (the  "Merger")  of OTN  Acquisition  Sub Inc.,  a
Delaware  corporation and wholly owned  subsidiary of BMS ("BMS Sub"),  with and
into  Axion  following  the  Distribution,   with  Axion  surviving  the  Merger
(sometimes hereinafter referred to as the "Surviving Corporation").
See "The Merger".

               At the time of the  Distribution,  AHC  will  own all of  Axion's
business,  assets and  liabilities,  other  than the  Retained  Business,  which
includes the stock of OPUS Sub and certain other tangible and intangible  assets
and  liabilities of Axion and its  subsidiaries  including  2,700,000  shares of
Series A  Redeemable  Preferred  Stock of OnCare  Inc.  (the  "OnCare  Preferred
Stock"), a Delaware corporation  ("OnCare"),  and an amount in cash equal to the
Preference  Amount  (as  defined  herein),  plus all other cash of Axion and its
subsidiaries,  excluding the Retained Cash (as defined herein), and the Employee
Loans (as defined  herein) (such stock,  cash and other assets and  liabilities,
the "Acquired  Business").  Immediately  prior to the Time of  Distribution  (as
defined  herein),  the Acquired  Business will be transferred to AHC by Axion in
accordance with the Agreement and Plan of Distribution and  Reorganization to be
entered into prior to the  Distribution  among Axion,  AHC, OTNC, OPUS, OPUS Sub
Inc., a Delaware  corporation  and wholly owned  subsidiary of OPUS ("OPUS Sub")
and OTN,  the form of which is an Exhibit to the Merger  Agreement  (as  defined
below) and which is  attached  as  Appendix B to the Proxy  Statement/Prospectus
dated September 19, 1996 (the "Proxy Statement/Prospectus") (as such form may be
amended, supplemented or otherwise modified from time to time, the "Distribution
Agreement").   This  Information  Statement  (the  "Information  Statement")  is
attached as Appendix G to the Proxy Statement/Prospectus.  See "The Company" and
"The Distribution".

               No  consideration  will  be paid by  Axion  stockholders  for the
shares of AHC Preferred Stock to be received by them in the Distribution.  There
is currently no public trading market for the shares of AHC Preferred Stock. See
"Special Factors--Absence of Trading Market; Restrictions on Resale".

               The  Distribution has not yet been declared by the Axion Board of
Directors (the "Axion Board"),  and,  accordingly,  the Distribution Record Date
has not yet been  determined.  The  Distribution  is conditioned on, among other
things,  the  satisfaction  (or waiver by the party for whose  benefit  any such
condition exists) of all

conditions  (other  than  consummation  of the  Distribution)  to  the  parties'
obligations  to consummate  the Merger  provided for in the Amended And Restated
Agreement and Plan of Merger,  dated as of August 2, 1996 (as it may be amended,
supplemented or otherwise  modified from time to time, the "Merger  Agreement"),
among  Axion,  BMS and BMS Sub,  which is  attached  as  Appendix A to the Proxy
Statement/Prospectus to which this Information Statement is attached as Appendix
G. See "The Distribution--Terms of the Distribution Agreement--Conditions to the
Distribution". Also see "The Merger--Terms of the Merger Agreement".

                                        THE COMPANY

               AHC,  formed  by  Axion  in  1994,  engages  in  clinical/disease
management  of cancer,  consisting  of a  collection  of related  cancer-focused
healthcare  activities  designed to promote  provision  of the  highest  quality
cost-effective  cancer  care  by  office-based  oncologists.  This  consists  of
coordinating  clinical  studies of both  emerging and existing  cancer drugs and
treatments  developed by  pharmaceutical  and biotechnology  companies.  AHC has
derived   limited   revenues   to  date  from  such   services.   See   "Special
Factors--Business to be Conducted by AHC; Limited Operating History;  History of
Losses".

               Following the  Contributions  (as defined herein) and the Merger,
AHC's business will consist of the following:

               AHC  Business.  AHC  expects  that its  principal  business  will
consist of providing cancer-specific managed care services to cancer care payers
and  providers  (the "AHC  Business").  The AHC Business has  generated  limited
revenues and has incurred  losses since AHC's  formation in 1994. AHC was formed
to carry on the  clinical  studies  programs  which  Axion  began in 1987 and to
continue the development of oncology  disease  management  programs arising from
such clinical studies programs.

               OPUS Matrix  Business.  The OPUS Matrix Business  consists of (i)
computer software which provides office based oncology  practices with access to
drug and  treatment  information  and (ii) the  management  information  systems
currently  used to support  Axion's  businesses.  The OPUS Matrix  Business  has
incurred losses since its inception in 1994.

               The mailing address of the AHC's principal  executive  offices is
1111 Bayhill Drive, Suite 125, San Bruno, California 94066. See "The Company".
    
                                THE TRANSACTIONS

               AHC is currently a wholly owned  subsidiary  of Axion.  Axion has
entered  into the Merger  Agreement  whereby,  upon the terms and subject to the
conditions  set forth  therein,  BMS Sub will be merged with and into Axion with
Axion  surviving as a wholly owned  subsidiary of BMS. In connection with and in
order to  facilitate  the  Merger,  Axion has agreed to effect,  pro rata to its
stockholders immediately prior to the effectiveness

                                       1

of  the  Merger,  the  Distribution  of all of  the  outstanding  shares  of AHC
Preferred  Stock,  which  should be tax-free to Axion  stockholders  for federal
income  tax  purposes  except  to the  extent  of  cash  payments  received  for
fractional shares. See "Certain Federal Income Tax Consequences".


                                     THE DISTRIBUTION

SUMMARY

               At  the  Time  of  Distribution,   the  Retained   Business  will
constitute all the  businesses,  assets and  liabilities  of Axion;  all Axion's
other businesses,  assets and liabilities,  which will include the AHC Business,
the  OPUS  Matrix  Business,  the  OnCare  Preferred  Stock,  all  cash and cash
equivalents  of Axion and its  subsidiaries  (other than Retained  Cash) and the
Employee Loans will be held by AHC. The  Distribution  Agreement  provides for a
series of asset and stock transfers and liability  assumptions between and among
Axion, AHC and certain of Axion's  subsidiaries prior to the Distribution.  Such
asset and stock transfers and liability assumptions are designed to separate the
Acquired  Business,  which is not being acquired by BMS in the Merger,  from the
Retained Business prior to the Time of Distribution.  Accordingly,  the Retained
Business will  constitute all the business,  assets and  liabilities of Axion at
the  Effective  Time.  The purpose of this  complex  structure  is to permit the
disposition of the Retained Business in a transaction that should be tax-free to
Axion's  stockholders in which Axion  stockholders will receive BMS Common Stock
and will also  retain  their  proportionate  equity  interests  in the  Acquired
Business in the form of AHC Preferred Stock to be received in the Distribution.

SECURITIES TO BE DISTRIBUTED

               All outstanding  shares of AHC Preferred Stock,  which equals the
quotient of the number of shares of Axion Common Stock  outstanding  immediately
prior to the Time of  Distribution  (as defined below)  (including any shares of
Axion Common Stock issued in connection  with the conversion of Axion  Preferred
Stock to Axion  Common  Stock and the  exercise  of Axion  Options  (as  defined
herein), in each case in connection with the consummation of the Merger).  Based
on the Diluted Share  Assumption (as defined  herein) (and assuming  exercise of
all Axion Options other than the Goldberg  $10.00 Options (as defined  herein)),
it is estimated that 9,970,509 shares of AHC Preferred Stock will be distributed
pursuant to the Distribution.  See "The  Distribution--Terms of the Distribution
Agreement--The  Distribution"  and  "Comparison  of Certain Rights of Holders of
Stock".

TIME OF DISTRIBUTION

               The  Distribution  is  expected  to be  effective  (the  "Time of
Distribution")  immediately prior to the Merger's  effectiveness (the "Effective
Time").  Stock  certificates for shares of AHC Preferred Stock will be mailed as
soon as practicable after the Time of Distribution. See "The Distribution--Terms
of the Distribution Agreement--The Distribution".
    
DISTRIBUTION RECORD DATE

               It  is  expected  that  the  Distribution  Record  Date  will  be
established  as the day on  which  the  Time of  Distribution  occurs.  See "The
Distribution--Terms of the Distribution Agreement".


TRADING MARKET
   
               There is no existing  trading market for AHC Preferred Stock. AHC
has not sought and does not intend to apply for listing of AHC  Preferred  Stock
on a securities  exchange or seek  approval for  quotation  through an automated
quotation system. THERE CAN BE NO ASSURANCE THAT ANY TRADING MARKET WILL DEVELOP
FOR AHC PREFERRED  STOCK. In addition,  the certificate of  incorporation of AHC
(the "AHC Certificate of Incorporation") will be amended and restated to provide
for various  restrictions  on transfer of AHC Preferred Stock (as so amended and
restated,  the "Restated AHC Certificate") which is attached to this Information
Statement as Appendix I. The Restated  AHC  Certificate  and Restated AHC Bylaws
provide for the same  restrictions  on transfer to be placed on 
    
                                        2

AHC Common Stock once such stock is issued. The certificates  evidencing the AHC
Preferred Stock will bear a legend referring to these  restrictions on transfer.
See "Special  Factors--Absence  of Trading  Market;  Restrictions on Resale" and
"Trading of AHC Preferred Stock".

CONDITIONS TO DISTRIBUTION

               Consummation of the Distribution is subject to the conditions set
forth in the  Distribution  Agreement,  which include that all conditions to the
closing of the Merger set forth in the Merger  Agreement  to be  satisfied.  See
"The Distribution Agreement--Terms of the Distribution  Agreement--Conditions to
the Distribution" and "The Merger".

TRANSFER AGENT

               Gunderson  Dettmer Stough  Villeneuve  Franklin & Hachigian,  LLP
will act as transfer agent for the Distribution.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE DISTRIBUTION

               Ernst & Young LLP ("Ernst & Young"), certified public accountants
to Axion,  have  rendered  an  opinion to the effect  that,  based upon  certain
representations  of BMS, BMS Sub, Axion, AHC and certain  stockholders of Axion,
among  other  things,  the  Distribution  should  qualify as a tax-free  spinoff
pursuant to Section 355 of the Internal  Revenue  Code of 1986,  as amended (the
"Code"),  and, as a result,  holders of Axion Common  Stock should  recognize no
gain  or  loss  upon  the  receipt  of  AHC  Preferred  Stock  pursuant  to  the
Distribution.  Consummation of the Distribution and the Merger is conditioned on
a  reaffirmation  of that opinion at the Time of  Distribution by Ernst & Young.
Such  opinion  is based  on Ernst &  Young's  interpretation  as to how  various
requirements  of Section 355 of the Code should  apply to the  particular  facts
presented by the Distribution. With respect to some of these interpretations, no
direct legal precedents exist.  Accordingly,  THERE CAN BE NO ASSURANCE THAT THE
IRS WILL AGREE WITH THE CONCLUSIONS  SET FORTH IN THE ERNST & YOUNG OPINION.  No
rulings relating to the  Distribution  have been sought or will be received from
the Internal  Revenue Service (the "IRS"),  and the Ernst & Young opinion is not
binding on the IRS. Moreover, no published rulings or cases squarely address the
qualification  under Section 355 of the Code of a  transaction  identical to the
Distribution.  If the IRS were to assert  successfully that the Distribution did
not  qualify  as  a  tax-free  spinoff  under  Section  355  of  the  Code,  the
Distribution  would be a taxable  transaction to Axion and the  stockholders  of
Axion immediately prior to the Effective Time (the "Former Axion  Stockholders")
for federal income tax purposes. STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS REGARDING SUCH TAX CONSEQUENCES.  Even if the Distribution does qualify
as a tax-free spinoff under Section 355 of the Code, the distribution of the AHC
Preferred  Stock by Axion to Non-United  States Holders (as defined herein) will
constitute  a  taxable  event  to  Axion.   See  "Certain   Federal  Income  Tax
Consequences".

               To the  extent of the tax  liabilities  to Axion  that will arise
from the distribution of AHC Preferred Stock to Non-United  States Holders,  BMS
will seek  indemnification  from AHC,  the 81% AHC  Subsidiaries  and the Former
Axion  Stockholders  pursuant  to the  Tax  Matters  Agreement  and  the  Escrow
Agreement.  In  addition,  if,  notwithstanding  receipt  of  such  opinion  and
reaffirmation  from Ernst & Young, it is determined that the  Distribution  does
not qualify as a tax-free  spinoff under  Section 355 of the Code,  then BMS may
seek  indemnification  from AHC, the 81% AHC  Subsidiaries  and the Former Axion
Stockholders  pursuant  to the terms of the Tax  Matters  Agreement  (as defined
herein) and the Escrow Agreement (as defined  herein).  Such events could result
in failure by the Former Axion  Stockholders to obtain the release of any of the
Escrowed Shares (as defined herein), could result in AHC's failure to obtain the
release of any of the Escrowed Cash (as defined herein) and could require AHC to
provide  additional funds to indemnify BMS. Failure by AHC to obtain the release
of the Escrowed Cash, or the  requirement  of additional  payments by AHC, could
have a material  adverse effect on AHC or the value of the AHC Preferred  Stock.
See "Indemnification  Arrangements--Terms of the Escrow Agreement",  "--Terms of
the Tax Matters Agreement" and "Special Factors--Indemnification  Obligations of
the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries", "--Business to
be  conducted  by  AHC;  Limited  Operating  History,  History  of  Losses"  and
"--Certain Federal Income Tax Consequences of the Distribution".

DIVIDENDS AFTER THE DISTRIBUTION
   
               AHC does not  anticipate  declaring and paying cash  dividends on
the AHC  Preferred  Stock at any time in the  foreseeable  future.  The decision
whether to apply legally  available funds to the payment of dividends on the AHC
Preferred  Stock will be made by the Board of Directors of AHC (the "AHC Board")
from time to time in the exercise of its business judgment, taking into account,
among other things,  AHC's results of operations and financial condition and any
then existing or proposed commitments for the use by AHC of available funds. See
"Special  Factors--Dividends  and Dividend  Policy" and  "Description of Capital
Stock--AHC Preferred Stock".

RESTRICTIONS ON DIVIDENDS AND REDEMPTIONS

               The  Indemnification  Agreement (as defined herein)  provides for
restrictions on AHC's ability to declare  dividends for a period of in excess of
6 years from the Effective Time (subject to extension in certain circumstances).
The Indemnification  Agreement also prohibits AHC from making redemptions of its
capital  stock for a period  of 6 years  from the  Effective  Time  (subject  to
extension  in  certain  circumstances).  See  "The  Distribution--Terms  of  the
Distribution Agreement--The Indemnification Agreement".

CERTAIN PROVISIONS OF THE RESTATED AHC CERTIFICATE AND RESTATED AHC BYLAWS

               Certain  provisions  of the  Restated  AHC  Certificate  and  the
Restated  Bylaws of AHC as they are anticipated to be amended and restated prior
to the Distribution attached to this Information Statement as Appendix II (as so
amended and restated,  the  "Restated  AHC  Bylaws"),  may be deemed to have the
effect of making difficult an acquisition of control of AHC in a transaction not
approved  by the AHC  Board.  See  "Special  Factors--Substantial  Stockholders;
Certain  Provisions of the Certificate of Incorporation" and "Description of AHC
Capital  Stock--Description  of Certain  Certificate of Incorporation  and Bylaw
Provisions".

MERGER AGREEMENT

               If the Merger  Agreement  is  approved  and  adopted by the Axion
stockholders  and the other conditions to the Merger are satisfied (or waived by
the party for whose benefit such condition exists), at the time of effectiveness
of the Merger (the "Effective Time"), BMS Sub will be merged with and into Axion
(which will then hold only the Retained  Business)  with Axion as the  Surviving
Corporation, and the separate existence of BMS Sub will cease.

               Pursuant  to the Merger  Agreement,  at the  Effective  Time each
share of Axion Common Stock outstanding  immediately prior to the Effective Time
(other than any shares of Axion Common Stock owned by Axion or any subsidiary of
Axion or BMS or any  subsidiary of BMS and any shares of Axion Common Stock (the
"Dissenting  Shares") with respect to which appraisal rights have been perfected
in accordance with Section 262 of Delaware General Corporation Law (the "DGCL"))
will be converted  into the right to receive the  Conversion  Number (as defined
herein) of fully paid and  nonassessable  shares of common stock, par value $.10
per  share,  of BMS  together  with the  associated  rights  (the "BMS  Rights")
pursuant to the Rights  Agreement dated as of December 4, 1987 (as amended,  the
"Rights  Agreement")  between BMS and The Chase  Manhattan Bank, as Rights Agent
(collectively,  "BMS Common  Stock") equal to the quotient of (a)(i) $86 million
divided  by (ii) the  Average  Value of BMS  Common  Stock (as  defined  herein)
divided  by  (b)  the  number  of  shares  of  Axion  Common  Stock  outstanding
immediately  prior to the Effective  Time  (calculated  on a fully diluted basis
assuming that each share of Axion Preferred Stock outstanding  immediately prior
to the Effective Time has been  converted in accordance  with its terms into one
share of Axion Common  Stock and that all  options,  warrants or other rights to
acquire Axion Common Stock ("Axion  Options")  outstanding  immediately prior to
the Effective Time have been exercised or canceled and that the related  subject
shares (other than any subject shares related to any portion of any Axion Option
that shall have been  canceled  and not  exercised)  of Axion  Common  Stock are
outstanding (collectively,  the "Diluted Share Assumption")).  The term "Average
Value of BMS Common Stock" means an amount equal to the average of the per share
closing  prices of BMS Common  Stock as reported on the New York Stock  Exchange
Composite  Transaction  Tape (the "NYSE Tape") for the 10  consecutive  full New
York Stopck Exchange ("NYSE") trading days ending on the fifth full NYSE trading
day immediately  preceding the Effective Time; provided that (A)
    

                                       4

if the Board of Directors of BMS (the "BMS Board")  declares a cash  dividend on
the  outstanding  shares of BMS  Common  Stock  having a record  date  after the
Effective  Time but an  ex-dividend  date (based on "regular way" trading on the
NYSE of shares of BMS  Common  Stock,  the  "Ex-Date")  that  occurs  during the
averaging period, then for purposes of computing the Average Value of BMS Common
Stock,  the closing  price on the  Ex-Date and any trading day in the  averaging
period after the Ex-Date  will be adjusted by adding  thereto the amount of such
dividend and (B) if the BMS Board  declares a cash  dividend on the  outstanding
shares of BMS Common Stock having a record date before the Effective Time and an
Ex-Date that occurs during the averaging period,  then for purposes of computing
the Average  Value of BMS Common  Stock,  the  closing  price on any trading day
before the Ex-Date will be adjusted by subtracting  therefrom the amount of such
dividend.  Notwithstanding  anything  to the  contrary  contained  in the Merger
Agreement,  in the event that as of the closing date of the Merger (the "Closing
Date")  the  Average  Value of BMS Common  Stock is less than  $82.73 (an amount
equal to 95 percent of the daily  average per share  closing price of BMS Common
Stock as reported on the NYSE Tape for the 10 full NYSE trading days immediately
prior to the date of the Merger Agreement) (the "Minimum  Price"),  then for the
purposes of calculating the Merger Consideration the Average Value of BMS Common
Stock  will be deemed to be an amount  equal to the  Minimum  Price,  and in the
event that as of the  Closing  Date the  Average  Value of BMS  Common  Stock is
greater  than $91.43 (an amount  equal to 105  percent of the daily  average per
share  closing price of BMS Common Stock as reported on the NYSE Tape for the 10
full NYSE trading days  immediately  prior to the date of the Merger  Agreement)
(the  "Maximum  Price"),  then  for  the  purposes  of  calculating  the  Merger
Consideration,  the  Average  Value of BMS Common  Stock will be deemed to be an
amount equal to the Maximum Price,  in each case subject to certain  adjustments
for  dividends.  If prior to the Effective  Time the BMS Board  declares a stock
split, stock combination,  stock dividend or other non-cash  distribution on the
outstanding  shares of BMS Common  Stock,  the Minimum  Price and Maximum  Price
(and,  if the Ex-Date for such event occurs  during the  averaging  period,  the
Average  Value of BMS Common  Stock) will be  appropriately  adjusted to reflect
such split, combination, dividend or other distribution.

               Based on the Diluted Share  Assumption (and assuming  exercise of
all Axion Options other than the Goldberg  $10.00  Options (as defined  herein),
resulting  in  an   aggregate   of  9,970,509   shares  of  Axion  Common  Stock
outstanding),  and assuming an Average Value of BMS Common Stock equal to $92.83
(the  average per share  closing  price of BMS Common Stock for the 10 full NYSE
trading days ending  September  18, 1996,  the most recent full NYSE trading day
available prior to printing this Proxy Statement/Prospectus), in which event the
Conversion  Number would be  calculated  based on an Average Value of BMS Common
Stock equal to the Maximum Price of $91.43,  (a) the Conversion  Number would be
0.094  and (b)  assuming  a  market  value of the BMS  Common  Stock on the date
received by holders of Axion Common Stock in the Merger of $92.83, the aggregate
market value of BMS Common Stock to be received by holders of Axion Common Stock
in the Merger would be approximately  $87 million,  or  approximately  $8.73 per
share of Axion Common Stock.  THERE CAN BE NO ASSURANCE  THAT THESE  ASSUMPTIONS
WILL BE TRUE AS OF THE EFFECTIVE TIME.

               The Average  Value of BMS Common Stock is  determined  as of five
full NYSE trading days immediately  preceding the Effective Time (which date may
be after the date of the Special  Meeting of Stockholders of Axion to be held on
October 18, 1996, and any  adjournments or  postponements  thereof (the "Special
Meeting"),  at which time the Average Value of BMS Common Stock may be less than
the  assumed  $92.83  Average  Value of BMS Common  Stock  referred to above and
indeed may be less than the Minimum  Price.  If the Average  Value of BMS Common
Stock at such time is between the Minimum  Price  ($82.73) and the Maximum Price
($91.43),  the  aggregate  market  value of BMS Common  Stock to be  received by
holders  of  Axion  Common  Stock  in  the  Merger  will  be  $86  million,   or
approximately  $8.63 per share of Axion Common Stock (based on the Diluted Share
Assumption  and assuming  exercise of all Axion  Options other than the Goldberg
$10.00  Options).  If the Average Value of BMS Common Stock at such time is less
than the Minimum  Price,  the  aggregate  market value of BMS Common Stock to be
received by holders of Axion Common Stock in the Merger will be less, and may be
substantially  less, than $86 million, or approximately $8.63 per share of Axion
Common Stock (based on the Diluted Share Assumption and assuming exercise of all
Axion Options other than the Goldberg $10.00 Options).  The foregoing statements
in this  paragraph  assume  that the  market  value of BMS  Common  Stock on the
Closing  Date is equal to the  Average  Value of the BMS  Common  Stock  used to
calculate the Conversion Number.  However, the actual market value of BMS Common
Stock on the Closing Date may be  substantially  less than the Average  Value of
BMS Common Stock used to calculate the Conversion  Number.  The actual aggregate
market  value on the  Closing

Date of BMS Common Stock received by holders of Axion Common Stock in the Merger
will be equal to the number of shares of BMS Common  Stock  issued in the Merger
multiplied by the market value of the BMS Common Stock on the Closing Date.

               UNDER THE TERMS OF THE MERGER AGREEMENT,  AXION DOES NOT HAVE THE
RIGHT TO DECLINE TO  CONSUMMATE  THE MERGER  SOLELY  BECAUSE  EITHER THE AVERAGE
VALUE OF BMS COMMON STOCK USED TO CALCULATE THE  CONVERSION  NUMBER IS LESS THAN
THE MINIMUM  PRICE OR BECAUSE THE ACTUAL MARKET VALUE OF BMS COMMON STOCK ON THE
CLOSING  DATE IS LESS  THAN  THE  AVERAGE  VALUE  OF BMS  COMMON  STOCK  USED TO
CALCULATE THE CONVERSION  NUMBER.  THEREFORE,  IF THE MERGER PROPOSAL IS ADOPTED
AND APPROVED AND ALL OTHER  CONDITIONS TO THE MERGER ARE SATISFIED (OR WAIVED BY
THE  PARTY FOR  WHOSE  BENEFIT  ANY SUCH  CONDITION  EXISTS)  AT OR PRIOR TO THE
EFFECTIVE  TIME,  AXION  STOCKHOLDERS  WILL  ASSUME THE RISK OF A DECLINE IN THE
MARKET VALUE OF BMS COMMON  STOCK BELOW THE MINIMUM  PRICE AND THE RISK THAT THE
ACTUAL  MARKET  VALUE OF BMS COMMON  STOCK ON THE CLOSING  DATE IS LESS THAN THE
AVERAGE VALUE OF BMS COMMON STOCK USED TO CALCULATE THE  CONVERSION  NUMBER AND,
ACCORDINGLY,  THE RISK THAT THE AGGREGATE MARKET VALUE OF BMS COMMON STOCK TO BE
RECEIVED  BY  THE  HOLDERS  OF  AXION   COMMON  STOCK  IN  THE  MERGER  WILL  BE
SUBSTANTIALLY  LESS THAN $86 MILLION OR APPROXIMATELY  $8.63 PER SHARE (BASED ON
THE DILUTED SHARE  ASSUMPTION  AND ASSUMING  EXERCISE OF ALL AXION OPTIONS OTHER
THAN THE GOLDBERG $10.00 OPTIONS).

               In addition,  the number of assumed  outstanding  shares of Axion
Common Stock for the purpose of calculating the Conversion  Number is determined
as of immediately  prior to the Effective Time (which date may be after the date
of the Special Meeting),  at which time the actual number of outstanding  shares
of Axion Common Stock may be greater than the assumed  9,970,509 shares referred
to above.  Each share of Axion Common Stock will be converted in the Merger into
the right to receive the  Conversion  Number of shares of BMS Common Stock.  Any
increase in the actual number of outstanding  shares of Axion Common Stock as of
immediately prior to the Effective Time would result in a corresponding decrease
in the Conversion Number and, accordingly, in the number of shares of BMS Common
Stock to be received in respect of each share of Axion Common Stock. The maximum
number of shares of Axion Common Stock that may be outstanding as of immediately
prior to the Effective Time is 10,070,509 shares.

               The  foregoing is a brief  summary of certain terms of the Merger
affecting AHC. A complete  description  of the Merger and the Merger  Agreement,
which is attached as Appendix A to the Proxy  Statement/Prospectus to which this
Information  Statement  is  attached  as  Appendix  G, may be found in the Proxy
Statement/Prospectus. The Distribution Agreement between AHC, Axion, OTNC, OPUS,
OPUS Sub and OTN is more fully described herein under "The Distribution".

THE DISTRIBUTION AGREEMENT

               The  Distribution  Agreement  provides  for a series of asset and
stock transfers and liability assumptions, including the Contributions,  between
and  among  Axion,  AHC  and  certain  of  Axion's  subsidiaries  prior  to  the
Distribution.   Such  asset  and  stock  transfers  and  liability  assumptions,
including  the  Contributions,  are designed to separate the Acquired  Business,
which is not being  acquired by BMS in the Merger,  from the  Retained  Business
prior to the Time of  Distribution.  Accordingly,  the  Retained  Business  will
constitute  all the business,  assets and  liabilities of Axion at the Effective
Time. The purpose of this complex  structure is to permit the disposition of the
Retained  Business  in a  transaction  that  should be tax-free to Axion and its
stockholders in which Axion  stockholders will receive BMS Common Stock and will
also retain their proportionate equity interests in the Acquired Business in the
form of AHC  Preferred  Stock to be received in the  Distribution.  In the event
Axion  stockholders  do not approve the Merger,  or if the Merger  Agreement  is
otherwise terminated, Axion nonetheless intends to consummate the Contributions.
See  "Special   Factors--Certain   Federal  Income  Tax   Consequences   of  the
Distribution"   and  "Certain   Federal  Income  Tax   Consequences"   and  "The
Distribution".

               The  Distribution  will be effected by the  distribution  to each
holder of record of Axion Common  Stock,  as of the close of the stock  transfer
books on the Distribution Record Date, of certificates representing one share of
AHC  Preferred  Stock for each share of  outstanding  Axion Common Stock held of
record by such holder and by the  distribution to each holder of Axion Preferred
Stock,  as of the  Distribution  Record Date, of certificates
    

                                       6

representing  one share of AHC Preferred Stock for each share of Axion Preferred
Stock  held of  record  by such  holder.  See  "The  Distribution--Terms  of the
Distribution Agreement".

               Although the Distribution  will not be effected unless the Merger
is approved and about to occur,  the  Distribution  is separate from the Merger,
and the AHC Preferred  Stock to be received by holders of Axion Common Stock and
holders of Axion Preferred Stock in the Distribution  does not constitute a part
of the consideration to be received by Axion  stockholders in the Merger.  Axion
stockholders  are not being  asked to  approve  the  Distribution,  which is not
subject  to  stockholder   approval.   Axion  stockholders  should  review  this
Information   Statement  for   additional   information   with  respect  to  the
Distribution, the Acquired Business and the AHC Preferred Stock. Consummation of
the Distribution is a condition to the Merger.

               BMS,  Axion,  BMS Sub, AHC and certain  other  parties will enter
into certain agreements, as applicable, designed to effectuate the separation of
the Acquired Business from the Retained Business and to facilitate the operation
of AHC as a separate  entity.  Each of the Former Axion  Stockholders  will also
become a party to certain of those agreements. See "The Distribution".

THE INDEMNIFICATION AGREEMENT

               AHC, the 81% AHC Subsidiaries (as defined herein) (including OPUS
Sub), the Former Axion Stockholders,  BMS, the Surviving Corporation, OPUS, OTNC
and the Partnership will enter into a Post-Closing Covenants and Indemnification
Agreement,   the  form  of  which  is  attached  as  Appendix  C  to  the  Proxy
Statement/Prospectus to which this Information Statement is attached as Appendix
G and is incorporated herein by reference (as it may be amended, supplemented or
otherwise modified from time to time, the "Indemnification Agreement"), pursuant
to which AHC,  the 81% AHC  Subsidiaries  (including  OPUS Sub) and each  Former
Axion Stockholder (collectively,  the "AHC Indemnifying Parties") will indemnify
BMS, the Surviving Corporation, OTNC, OPUS, the Partnership and their respective
subsidiaries  and affiliates  against certain  Indemnifiable  Losses (as defined
herein) relating to or arising from any breach of any  representation,  warranty
or covenant of Axion or any of its  subsidiaries  in any Document;  any material
misstatements or omissions contained in the Proxy  Statement/Prospectus to which
this Information Statement is attached as Appendix G, this Information Statement
or any Required AHC  Document  (as defined  herein) with respect to  information
related to Axion and its subsidiaries  (including OTN); the Acquired Assets, the
Assumed  Liabilities and the Acquired  Business and the business of AHC and OPUS
Sub (other than Retained Liabilities (as defined herein)); the business of Axion
and its  subsidiaries  (including  OTN) prior to the Merger (other than Retained
Liabilities);  claims of  stockholders  and certain  other persons to the extent
relating to or arising from the  execution  by Axion or any of its  subsidiaries
(including OTN) of any of the Documents or the  consummation of the transactions
contemplated  thereby  (including claims for  indemnification  by any officer or
director of Axion or any of its subsidiaries  (including OTN)); the Excess Axion
Expenses (as defined  herein);  any breach of terms,  covenants  or  conditions,
gross  negligence or wilful  misconduct and certain  liabilities  related to the
existing contractual arrangements between BMS, on the one hand, and OTNC and the
Partnership,  on the other hand; but excluding  Indemnifiable Losses relating to
tax liabilities,  which are the subject of the Tax Matters Agreement (as defined
below). The indemnification obligations of the Former Axion Stockholders will be
secured by the Escrowed Shares, and the  indemnification  obligations of AHC and
its  subsidiaries  will be  secured  by the  Escrowed  Cash,  on the  terms  and
conditions   set  forth  in  the   Escrow   Agreement   described   below.   The
indemnification  obligations of each of the Former Axion  Stockholders under the
Indemnification  Agreement  will be  limited in amount to the  Escrowed  Shares,
except in certain circumstances involving fraud,  intentional  misrepresentation
or intentional  breach of a covenant by any such Former Axion  Stockholder.  The
indemnification  obligations  of AHC and the 81% AHC  Subsidiaries  will  not be
limited in amount to the Escrowed Cash.

               In addition,  AHC and each of the 81% AHC Subsidiaries  each have
agreed  for a period  of six  years  following  the  Closing  Date  (subject  to
extension in certain circumstances) to certain restrictive covenants,  including
prohibitions  on  liquidation,  payment  of  dividends  or  other  distributions
(including by redemption or repurchase) with respect to any of its capital stock
and transactions with affiliates  (including  OnCare) on a nonarms' length basis
and restrictions  related to mergers or sales of all or substantially  all their
assets.  These prohibitions and restrictions are intended to prevent AHC and the
81% AHC Subsidiaries from engaging in
    

                                       7

transactions  that might have the effect of  limiting  the  availability  of the
assets of AHC and the 81% AHC  Subsidiaries  to  satisfy  their  indemnification
obligations under the Indemnification Agreement and the Tax Matters Agreement to
the BMS Indemnified  Parties (as defined herein).  BMS and its subsidiaries will
also indemnify AHC and its subsidiaries with respect to certain matters.

               Indemnification liabilities for losses arising from or related to
any breach of any  representation,  warranty  or covenant by Axion or any of its
subsidiaries in any Document or any losses  directly  related to OTN or the OPUS
Station  Business  are subject to a $500,000  threshold  and a $12 million  cap.
Indemnification liabilities for losses relating to or arising out of breaches of
any  representation,  warranty or covenant  that is directly  related to OTN are
limited  to 50%  of  the  amount  of  such  losses.  All  other  indemnification
obligations  are not  subject  to a  threshold  and  are  unlimited  in  amount.
Indemnification  obligations for losses related to or arising from any breach of
representation  or warranty of Axion or any of its subsidiaries  (including OTN)
in any of the  Documents  terminate  on March 31,  1998 (or in  certain  limited
circumstances,  on  the  third  anniversary  of the  Closing  Date).  All  other
indemnification  obligations  survive  in  perpetuity.  None  of  the  foregoing
limitations  will  apply  in  certain  circumstances   involving  fraud  or  any
misrepresentation  or breach of which Axion,  AHC or any 81% AHC  Subsidiary  or
their respective  officers or directors had knowledge or any intentional  breach
of any covenant by such person. See "Indemnification  Arrangements--Terms of the
Indemnification Agreement",  "--Terms of the Tax Matters Agreement" and "--Terms
of the Escrow  Agreement",  "Relationship with  BMS--Indemnification  Agreement;
Escrow Agreement;  Tax Matters Agreement" and "Special  Factors--Indemnification
Obligations of the Former Axion Stockholders, AHC and the 81% AHC Subsidiaries".

THE TAX MATTERS AGREEMENT

               BMS,  the  Surviving   Corporation,   the  81%  AHC  Subsidiaries
(including OPUS Sub) and AHC, on its own behalf and as representative of (a) the
81% AHC Subsidiaries and (b) each of the Former Axion  Stockholders,  will enter
into a Tax Matters Agreement, the form of which is attached as Appendix D to the
Proxy  Statement/Prospectus  to which this Information  Statement is attached as
Appendix  G and is  incorporated  herein  by  reference  (as it may be  amended,
supplemented  or  otherwise  modified  from  time  to  time,  the  "Tax  Matters
Agreement") which sets forth each party's rights and obligations with respect to
certain tax  payments,  tax  refunds  and  control of  contests  relating to tax
matters and also provides for (i) AHC, the 81% AHC  Subsidiaries and each of the
Former Axion  Stockholders  to indemnify BMS, the Surviving  Corporation,  OTNC,
OPUS, the  Partnership  and their  respective  subsidiaries  and affiliates from
certain tax liabilities (including tax liabilities that would arise or that will
arise to the extent the Contributions, the Distribution and related transactions
generate  taxable income) and (ii) BMS, the Surviving  Corporation,  OPUS, OTNC,
and the  Partnership  to indemnify  AHC,  OPUS Sub and each of their  respective
subsidiaries   and   affiliates   from  certain  other  tax   liabilities.   The
indemnification  obligations of the Former Axion Stockholders will be secured by
the  Escrowed  Shares,  and  the  indemnification  obligations  of AHC  and  its
subsidiaries  will be secured by the Escrowed  Cash, on the terms and conditions
set  forth  in  the  Escrow  Agreement   described  below.  The  indemnification
obligations  of each of the  Former  Axion  Stockholders  will be limited to the
Escrowed Shares,  except in certain circumstances  involving fraud,  intentional
misrepresentation  or intentional  breach of a covenant by any such Former Axion
Stockholder. The indemnification obligations of AHC and the 81% AHC Subsidiaries
will not be limited in amount to the Escrowed Cash. In addition, AHC and each of
the 81% AHC  Subsidiaries  have agreed for a period of six years  following  the
Closing  Date  (subject  to  extension  in  certain  circumstances)  to  certain
restrictive  covenants,  including  prohibitions  on  liquidation,   payment  of
dividends or other  distributions  (including by redemption or repurchase)  with
respect to any of its capital stock and transactions with affiliates  (including
OnCare) on a non-arms' length basis and restrictions related to mergers or sales
of all or substantially  all their assets.  These  prohibitions and restrictions
are  intended  to prevent  AHC and the 81% AHC  Subsidiaries  from  engaging  in
transactions  that might have the effect of limiting the  availability of assets
of AHC and the 81% AHC Subsidiaries to satisfy its  indemnification  obligations
under the  Indemnification  Agreement  and the Tax Matters  Agreement to the BMS
Indemnified Parties. See "Indemnification Arrangements--Terms of the Tax Matters
Agreement", "Relationship with BMS--Indemnification Agreement; Escrow Agreement;

THE ESCROW AGREEMENT

               BMS,  AHC,  the  81%  AHC   Subsidiaries  and  the  Former  Axion
Stockholders  and an escrow  agent to be selected by BMS and Axion (the  "Escrow
Agent")  will  enter  into an Escrow  Agreement,  the form of which is  attached
hereto as Appendix E to the Proxy Statement/Prospectus to which this Information
Statement is attached as Appendix G and is incorporated  herein by reference (as
it may be amended,  supplemented  or otherwise  modified from time to time,  the
"Escrow  Agreement")   pursuant  to  which  at  the  Closing  the  Former  Axion
Stockholders  will deposit the Escrowed Shares and AHC will deposit the Escrowed
Cash  into  escrow to  secure  the  indemnity  obligations  of AHC,  the 81% AHC
Subsidiaries  and  the  Former  Axion  Stockholders  under  the  Indemnification
Agreement and the Tax Matters Agreement. THERE CAN BE NO ASSURANCE AS TO WHETHER
ALL OR ANY PORTION OF THE  ESCROWED  SHARES WILL  EVENTUALLY  BE RELEASED TO THE
FORMER AXION STOCKHOLDERS. The indemnification obligations of each of the Former
Axion  Stockholders  will be limited to the Escrowed  Shares,  except in certain
circumstances  involving  fraud,  intentional  misrepresentation  or intentional
breach of a covenant by any such Former Axion  Stockholder,  and will  terminate
one year after the Closing  Date,  subject to a holdback of Escrowed  Shares for
any then Pending Claims (as defined  herein).  To the extent not previously paid
to BMS in respect of an  indemnification  loss, up to $4 million of the Escrowed
Cash may be released to AHC on the second  anniversary  of the Closing  Date and
the  balance  of  such  Escrowed  Cash  may be  released  to  AHC  on the  sixth
anniversary of the Closing Date, in each case subject to a holdback for any then
Pending Claims.  AHC and the 81% AHC Subsidiaries'  indemnification  obligations
are not limited to the  Escrowed  Cash.  THERE CAN BE NO ASSURANCE AS TO WHETHER
ALL OR ANY PORTION OF SUCH ESCROWED  CASH WILL  EVENTUALLY BE RELEASED TO AHC OR
THAT THE  INDEMNIFICATION  OBLIGATIONS OF AHC AND THE 81% AHC SUBSIDIARIES  WILL
NOT EXCEED THE AMOUNT OF THE  ESCROWED  CASH.  Failure to obtain the  release of
such Escrowed Cash or the incurrence of indemnification obligations in excess of
the  Escrowed  Cash  (which  AHC and the 81% AHC  Subsidiaries  may not have the
resources  to pay)  could  have a  material  adverse  effect on AHC's  business,
financial condition or results of operations and, accordingly,  the value of the
AHC  Preferred  Stock.  THERE ALSO CAN BE NO ASSURANCE  THAT AHC AND THE 81% AHC
SUBSIDIARIES  WILL  HAVE  SUFFICIENT   RESOURCES  OR  LIQUIDITY  TO  MEET  THEIR
INDEMNIFICATION OBLIGATIONS AND, ACCORDINGLY, THERE CAN BE NO ASSURANCE THAT THE
VALUE OF THE AHC PREFERRED STOCK WILL NOT BE MATERIALLY ADVERSELY AFFECTED.  See
"Indemnification  Arrangements--Terms of the Escrow Agreement",  "--Terms of the
Indemnification   Agreement",   "--Terms   of  the   Tax   Matters   Agreement",
"Relationship with BMS--Indemnification Agreement; Escrow Agreement; Tax Matters
Agreement",  "Special  Factors--Indemnification  Obligations of the Former Axion
Stockholders,  AHC and the 81% AHC Subsidiaries",  "--Certain Federal Income Tax
Consequences  of the  Distribution"  and  "--Business  to be  Conducted  by AHC;
Limited  Operating  History;  History of Losses" and "Certain Federal Income Tax
Consequences".

RELATIONSHIP WITH BMS AFTER THE DISTRIBUTION

               Following the Merger,  AHC and its subsidiaries  will continue to
have certain  relationships with BMS. AHC, the 81% Subsidiaries  (including OPUS
Sub), the Former Axion Stockholders,  BMS, the Surviving Corporation, OPUS, OTNC
and the Partnership will be parties to the  Indemnification  Agreement,  the Tax
Matters   Agreement   and   the   Escrow   Agreement.    See    "Indemnification
Arrangements--Terms  of the  Indemnification  Agreement,"  "--Terms  of the  Tax
Matters Agreement," and "--Terms of the Escrow Agreement".

               BMS has entered into separate Noncompetition  Agreements with AHC
and OnCare  and each of Michael D.  Goldberg,  the  President,  Chief  Executive
Officer and a director  of Axion,  OnCare and AHC,  and  Garrett J.  Roper,  the
Senior Vice President and Chief Financial  Officer of Axion,  OnCare and AHC and
the Secretary  and a director of AHC (the  "Noncompetition  Agreements"),  which
will become  effective at Closing and will, for two years  following the Closing
Date,  prohibit such entities or persons and their  affiliates,  as the case may
be,  from,  as  applicable,  ownership,  management,  operation  or control  of,
employment  by, holding  certain  equity  interests in or serving as a director,
advisor or consultant to, or having certain other relationships with, any entity
that engages in the  distribution  of oncology  drugs,  supplies or biologics to
certain customers of OTN or the automated drug dispensing and inventory tracking
systems   business   in   the   United   States.    See    "Relationship    with
BMS--Noncompetition Agreements".

               AHC has entered  into the AHC Supply  Agreement  (the "AHC Supply
Agreement")  with OTN and OnCare has entered  into the OnCare  Supply  Agreement
(the  "OnCare  Supply  Agreement")  with OTN which will become  effective at the
Closing and which  provide  that AHC and OnCare will use OTN as their  exclusive
provider of oncology  pharmaceutical  products  and  supplies  and that OTN will
provide such  products and supplies at the lowest price it offers to a specified
category of  purchaser  (subject to certain  conditions),  provided  that in the
event AHC or OnCare,  as the case may be, receives an offer pricing  products or
supplies  at a price of at least 10% less than the lowest  price  offered by OTN
and OTN chooses not to match such lower  offer,  AHC or OnCare,  as the case may
be, may purchase  such  products or supplies  pursuant to such lower offer for a
term to end upon the later of 30 days after the  receipt of such lower offer and
the term of such lower offer.  OTN's existing supply  agreement with OnCare will
be  terminated  on the Closing  Date.  AHC has entered  into the AHC  Medstation
Agreement  (the "AHC  Medstation  Agreement")  and OnCare has  entered  into the
OnCare  Medstation  Agreement  (the "OnCare  Medstation  Agreement")  which will
become  effective at the Closing and which  provide that AHC and OnCare will use
OPUS, as their exclusive provider of oncology drug dispensing  machines and that
OPUS will  provide  such  machines at the lowest  price it offers to a specified
category of purchaser  (subject to certain  conditions).  See "Relationship with
BMS--AHC Supply Agreement;  OnCare Supply Agreement;  AHC Medstation  Agreement;
OnCare Medstation Agreement".

               AHC and the  Surviving  Corporation  will enter into a  Trademark
License Agreement (the "License  Agreement") pursuant to which AHC will grant an
exclusive,  royalty-free license to the Surviving  Corporation to use the "OPUS"
name in  connection  with the OPUS Station  Business in the U.S. for a period of
one year. AHC and the Surviving  Corporation will also enter into a Transitional
Services Agreement (the "Transitional Services Agreement") pursuant to which AHC
and the  Surviving  Corporation  will  provide  certain  services  to each other
following  the  Merger.  See  "Relationship  with  BMS--License  Agreement"  and
"--Transitional Services Agreement".
    
SPECIAL FACTORS

               Stockholders  should  carefully  consider  the matters  discussed
under the section entitled "Special Factors" in this Information Statement.

   
                                      SPECIAL FACTORS

BUSINESS TO BE CONDUCTED BY AHC; LIMITED OPERATING HISTORY; HISTORY OF LOSSES

               Immediately  prior  to the  Time of  Distribution,  the  Acquired
Business will be transferred  to, and will comprise all of the business,  assets
and  liabilities,  of AHC. The business,  assets and liabilities of AHC will not
include the Retained Business, which accounted for approximately $133.0 million,
or 99.9%, of Axion's consolidated net revenues for the six months ended June 30,
1996, and $156.7 million,  or 98.5% of Axion's total assets as of June 30, 1996.
As a result,  AHC will be  substantially  smaller than Axion and will derive its
revenues  from a less diverse group of  businesses  and assets.  There can be no
assurance that AHC will be successful in implementing its business strategies or
that,  if  implemented,  such  strategies  will  result  in the  growth of AHC's
businesses.

               Axion  formed  AHC  in  1994  and   effective   January  1,  1995
contributed Axion's clinical studies business,  which began in 1987, to AHC. AHC
expects its principal business will be to engage in clinical/disease  management
of cancer,  consisting  of a  collection  of related  cancer-focused  healthcare
activities  designed to promote provision of the highest quality  cost-effective
cancer care by  office-based  oncologists.  AHC's prospects must be evaluated in
light of the risks, expenses and difficulties frequently encountered by recently
formed businesses.

               The  business,  financial  condition and results of operations of
AHC after the closing of the Merger (the "Closing") and, accordingly,  the value
of the AHC  Preferred  Stock  to be  received  by  stockholders  of Axion in the
Distribution  could be  materially  adversely  affected  by a number of  factors
involving several types of risks, including risks associated with AHC's business
and liquidity; with AHC's contingent indemnification  obligations to 
    


                                       10

BMS and its subsidiaries and the associated restrictive covenants limiting AHC's
ability  to  engage  in  certain  transactions;  with  the  federal  income  tax
consequences   of  the   Distribution   and  the   Merger;   and  with   certain
characteristics  of the AHC  Preferred  Stock and the potential  trading  market
therefor.

               The  business of AHC has not  generated  significant  revenues or
realized  a profit to date and has  operated  and is  expected  to  continue  to
operate  at a loss  for  the  foreseeable  future.  AHC  has  historically  been
dependent on Axion for funding, and AHC's future development is dependent on its
ability to obtain  sufficient  funding.  There can be no assurance that adequate
funds for such  development  will be available on acceptable  terms,  or at all.
There can be no assurance  that AHC will be able to achieve  profitability  on a
quarterly  or annual  basis in the future.  In such event,  or in the event that
adverse conditions prevail or are perceived to prevail generally or with respect
to AHC's  business,  the value of AHC Preferred Stock would likely be materially
adversely affected.  See "--Limited  Financial  Resources",  "--Risks Associated
with New  Business  Strategy"  and  "Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operation".

RISKS ASSOCIATED WITH NEW BUSINESS STRATEGY

               The cancer-specific managed care business in which AHC intends to
compete is characterized by rapid technological change, frequent introduction of
new products and  services,  changes in customer  demands and evolving  industry
standards.  The introduction of products and services embodying new technologies
and  the  emergence  of  new  industry  standards  can  render  existing  market
strategies  obsolete and  unmarketable.  AHC's future success will depend on its
ability to address the increasingly  sophisticated  needs of its customers as it
develops new business  strategies  to address the  cancer-specific  managed care
market.  There can be no assurance that AHC will be successful in developing and
marketing its products and services,  that AHC will not experience  difficulties
that  could  delay or  prevent  the  successful  development,  introduction  and
marketing of such products and services, or that AHC's new products and services
and product and service  enhancements  will adequately meet the  requirements of
the marketplace and achieve market  acceptance.  If AHC is unable to develop and
introduce  new products and services or  enhancements  of existing  products and
services  in a timely  manner in  response  to  changing  market  conditions  or
customer requirements, AHC's business, operating results and financial condition
will be materially adversely affected. See "The Company".

INDEMNIFICATION  OBLIGATIONS OF THE FORMER AXION  STOCKHOLDERS,  AHC AND THE 81%
AHC SUBSIDIARIES

               AHC,  the 81% AHC  Subsidiaries  (including  OPUS  Sub)  and each
Former Axion Stockholder will become a party to the  Indemnification  Agreement,
the  Tax  Matters  Agreement  and  the  Escrow  Agreement.   Pursuant  to  these
agreements, AHC, the 81% AHC Subsidiaries and the Former Axion Stockholders will
agree to indemnify the BMS  Indemnified  Parties  (including  BMS, the Surviving
Corporation,  OPUS,  OTNC  and the  Partnership)  against  certain  liabilities,
including   liabilities   relating  to  or  arising   from  any  breach  of  any
representation,  warranty  or  covenant  of  Axion  or any  of its  subsidiaries
(including  OTN)  in any  Document;  any  material  misstatements  or  omissions
contained in the Proxy  Statement/Prospectus to which this Information Statement
is attached as Appendix G or this  Information  Statement  or any  Required  AHC
Document  with  respect to  information  related  to Axion and its  subsidiaries
(including OTN); the Acquired Assets,  the Assumed  Liabilities and the Acquired
Business and the business of AHC and OPUS Sub (other than Retained Liabilities);
the business of Axion and its  subsidiaries  (including OTN) prior to the Merger
(other than  Retained  Liabilities);  claims of  stockholders  and certain other
persons to the extent  relating to or arising from the execution by Axion or any
of its subsidiaries  (including OTN) of any of the Documents or the consummation
of the transactions  contemplated  thereby (including claims for indemnification
by any  officer or  director  of Axion or any of its  subsidiaries);  the Excess
Axion Expenses; any breach of terms,  covenants or conditions,  gross negligence
or wilful misconduct and certain liabilities related to the existing contractual
arrangements between BMS, on the one hand, and OTNC and the Partnership,  on the
other hand;  certain  pre-closing tax liabilities of Axion and its  subsidiaries
(including  OTN);  and any tax  liabilities  that would  arise if,  contrary  to
expectations, the Contributions fail to be tax-free or the Distribution fails to
qualify as a tax-free spinoff.

               To  secure   these   indemnification   obligations,   immediately
following the Effective Time, the Escrowed Shares, valued at $5 million, will be
placed in escrow and AHC will place the  Escrowed  Cash of 
    

                                       11

$5 million in escrow.  In addition,  AHC and the 81% AHC Subsidiaries  each have
agreed  for a period  of six  years  following  the  Closing  Date  (subject  to
extension in certain circumstances) to certain restrictive covenants,  including
prohibitions  on  liquidation,  payment  of  dividends  or  other  distributions
(including by redemption or repurchase) with respect to any of its capital stock
and transactions with affiliates  (including OnCare) on a non-arms' length basis
and to certain  restrictions related to mergers or sales of all or substantially
all their assets.  These  prohibitions  and restrictions are intended to prevent
AHC and the 81% AHC Subsidiaries  from engaging in transactions  that might have
the effect of  limiting  the  availability  of the assets of AHC and the 81% AHC
Subsidiaries   to   satisfy   their   indemnification   obligations   under  the
Indemnification  Agreement and the Tax Matters  Agreement to the BMS Indemnified
Parties.

               Certain  of  the  AHC   Indemnifying   Parties'   indemnification
obligations are subject to agreed limitations.  Indemnification  liabilities for
losses arising from or related to any breach of any representation,  warranty or
covenant by Axion or any of its subsidiaries  (including OTN) in any Document or
any losses directly related to OTN or the OPUS Station Business are subject to a
$500,000 threshold and a $12 million cap. Indemnification liabilities for losses
relating  to or arising  out of  breaches  of any  representation,  warranty  or
covenant  that is  directly  related to OTN are  limited to 50% of the amount of
such losses.  All other  indemnification  obligations  are  unlimited in amount.
Indemnification  obligations for losses related to or arising from any breach of
representation  or warranty of Axion or any of its subsidiaries  (including OTN)
in any of the  Documents  terminate  on March 31,  1998 (or in  certain  limited
circumstances,  on  the  third  anniversary  of the  Closing  Date).  All  other
indemnification  obligations  survive  in  perpetuity.  None  of  the  foregoing
limitations  will  apply  in  certain  circumstances   involving  fraud  or  any
misrepresentation  or breach of which Axion,  AHC or any 81% AHC  Subsidiary  or
their respective  officers or directors had knowledge or any intentional  breach
of any covenant by any such person.

               The indemnification  obligations of each Former Axion Stockholder
will be limited in amount to such Former Axion  Stockholder's  pro rata share of
the  Escrowed  Shares,   except  in  certain   circumstances   involving  fraud,
intentional  misrepresentation  or intentional  breach of a covenant by any such
Former Axion  Stockholder,  and will  terminate one year after the Closing Date,
subject to a holdback of Escrowed  Shares for any  Pending  Claims.  During such
period  BMS will  recover  indemnification  from  the  Escrowed  Shares  even if
Escrowed Cash is also available in respect of an indemnifiable  loss, subject to
certain  exceptions.  THERE CAN BE NO ASSURANCE AS TO WHETHER ALL OR ANY PORTION
OF  SUCH   ESCROWED   SHARES  WILL   EVENTUALLY  BE  RELEASED  TO  FORMER  AXION
STOCKHOLDERS.

               To the  extent  not  previously  paid  to BMS  in  respect  of an
indemnifiable loss, up to $4 million of the Escrowed Cash may be released to AHC
on the second  anniversary  of the Closing Date and the balance of such Escrowed
Cash may be released to AHC on the sixth  anniversary  of the Closing  Date,  in
each case subject to a holdback for any then Pending Claims. AHC and the 81% AHC
Subsidiaries'  indemnification obligations are not limited to the Escrowed Cash.
THERE CAN BE NO ASSURANCE AS TO WHETHER ALL OR ANY PORTION OF SUCH ESCROWED CASH
WILL  EVENTUALLY BE RELEASED TO AHC OR THAT THE  INDEMNIFICATION  OBLIGATIONS OF
AHC AND THE 81% AHC  SUBSIDIARIES  WILL NOT EXCEED  THE  AMOUNT OF THE  ESCROWED
CASH.  Failure to obtain the release of such Escrowed Cash or the  incurrence of
indemnification  obligations  in excess of the Escrowed  Cash (which AHC and the
81% AHC  Subsidiaries  may not have the  resources to pay) could have a material
adverse effect on AHC's business,  financial  condition or results of operations
and,  accordingly,  the value of the AHC Preferred  Stock.  THERE ALSO CAN BE NO
ASSURANCE THAT AHC AND THE 81% AHC SUBSIDIARIES  WILL HAVE SUFFICIENT  RESOURCES
OR LIQUIDITY TO MEET THEIR INDEMNIFICATION  OBLIGATIONS AND, ACCORDINGLY,  THERE
CAN BE NO  ASSURANCE  THAT THE  VALUE  OF THE AHC  PREFERRED  STOCK  WILL NOT BE
MATERIALLY ADVERSELY AFFECTED.

               In addition,  the restrictive covenants referred to above and the
existence of potentially unlimited indemnification  obligations may restrict the
ability of AHC to obtain financing or engage in certain transactions,  including
acquisitions and strategic  alliances.  Failure to obtain financing or engage in
such  transactions  could  have a  material  adverse  effect on AHC's  business,
financial condition or results of operation and,  accordingly,  the value 
    

                                       12

of the AHC Preferred Stock,  independent of whether any indemnification payments
are actually made by or on behalf of AHC or the amount thereof.

               See "--Certain   Federal    Income    Tax    Consequences  of the
Distribution",  "Indemnification  Arrangements--Terms  of   the  Indemnification
Agreement",  "--Terms  of the  Tax Matters   Agreement"  and   "--Terms  of  the
Escrow   Agreement",   "Relationship   with   BMS--Indemnification    Agreement;
Escrow Agreement;  Tax Matters  Agreement"  and   "Certain  Federal  Income  Tax
Consequences".

               In  connection  with the tax  opinions  rendered  pursuant to the
Merger  and the  Distribution,  certain of the Former  Axion  Stockholders  have
signed or will sign letters  representing that they have no plan or intention to
sell or otherwise  dispose of any of their  holdings of (i) Axion  capital stock
prior to the Merger,  (ii) the AHC Preferred Stock received in the  Distribution
or (iii) the BMS  Common  Stock  received  in the  Merger  (the  "Continuity  of
Interest Letters").  In the event that a Former Axion Stockholder knowingly made
a  misrepresentation  in the Continuity of Interest  Letter that resulted in the
Merger failing to qualify as a tax-free reorganization under Code Section 368 or
the  Distribution  failing to qualify as a tax-free spinoff under Section 355 of
the Code, such  stockholder  would be individually  liable for all tax liability
resulting therefrom. See "Certain Federal Income Tax Consequences".

               See "--Certain Federal Income Tax Consequences", "Indemnification
Arrangements--Terms  of the  Indemnification  Agreement",  "--Terms  of the  Tax
Matters  Agreement" and "--Terms of the Escrow  Agreement",  "Relationship  with
BMS--Indemnification  Agreement;  Escrow Agreement;  Tax Matters  Agreement" and
"Certain Federal Income Tax Consequences".

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE DISTRIBUTION

               Ernst & Young has  rendered  an opinion to the effect  that based
upon the representations of BMS, BMS Sub, Axion, AHC and certain stockholders of
Axion, among other things, the Distribution should qualify as a tax-free spinoff
pursuant to Section 355 of the Code. Such opinion is not binding on the IRS, and
there is no assurance that the IRS (or any state or local taxing authority) will
agree with such opinion.  Consummation  of the  Distribution is conditioned on a
reaffirmation of that opinion at the Time of Distribution by Ernst & Young. Such
opinion  is  based  on  Ernst  &  Young's   interpretation  as  to  how  various
requirements  of Section 355 of the Code should  apply to the  particular  facts
presented by the Distribution. With respect to some of these interpretations, no
direct legal authority exists.  Accordingly,  there can be no assurance that the
IRS will agree with the conclusions  set forth in the Ernst & Young opinion.  No
ruling has been sought or will be received  from the IRS and such  opinions  are
not binding on the IRS. Moreover, no published rulings or cases squarely address
the qualifications  under Section 355 of the Code of a transaction  identical to
the  Distribution.  There is therefore no assurance that the IRS will not assert
successfully  that the Distribution  would be a taxable  transaction for federal
income  tax  purposes  and for other tax  purposes  as well.  If the IRS were to
assert   successfully  that  the  Distribution  did  not  qualify  for  tax-free
treatment,  then both the  distribution  by Axion of the AHC Preferred Stock and
the receipt by the Former Axion  Stockholders of such AHC Preferred Stock in the
Distribution would be a taxable  transaction to Axion and the Axion Stockholders
for federal  income tax  purposes.  Even if the  Distribution  does qualify as a
tax-free  spinoff under  Section 355 of the Code,  the  distribution  of the AHC
Preferred  Stock by Axion to Non-United  States Holders (as defined herein) will
constitute a taxable event to Axion.  As a result,  certain tax  liabilities  to
Axion will arise from the  distribution  of AHC  Preferred  Stock to  Non-United
States Holders (as defined  herein),  and to the extent of such tax  liabilities
BMS and the  Surviving  Corporation  will  seek  indemnification  under  the Tax
Matters  Agreement  from AHC,  the Former Axion  Stockholders  and the other AHC
Indemnifying  Parties.  Stockholders are urged to consult their own tax advisors
regarding such tax consequences. See "Certain Federal Income Tax Consequences".

               To the  extent  the  Distribution,  the  Contribution  and or the
related  transactions  are  determined  to be  taxable  to  Axion,  BMS  and the
Surviving  Corporation  have the right under the Tax Matters  Agreement  to seek
indemnification  from  AHC,  the  Former  Axion  Stockholders  and the other AHC
Indemnifying  Parties.  Such  Indemnification  may exceed the amount of Escrowed
Cash and  Escrowed  Shares then  remaining  (if any),  in which case AHC will be
required to pay such indemnification  directly.  Payment of such indemnification
may materially
    

                                       13


 
<PAGE>
 

<PAGE>
   
adversely affect AHC and, if AHC or the AHC  Indemnifying  Parties are unable to
pay such amounts,  payment of such tax claims may  materially  adversely  affect
Axion.  See  "Indemnification  Arrangements--Terms  of  the  Escrow  Agreement",
"--Terms  of  the  Tax  Matters  Agreement"  and  "Certain  Federal  Income  Tax
Consequences".

               In  connection  with the tax  opinions  rendered  pursuant to the
Merger  and the  Distribution,  certain of the Former  Axion  Stockholders  have
signed or will sign the  Continuity  of  Interest  Letters.  In the event that a
Former Axion Stockholder  knowingly made a misrepresentation  in a Continuity of
Interest  Letter that  resulted  in the Merger  failing to qualify as a tax-free
reorganization  under  Section  368 of the Code or the  Distribution  failing to
qualify as a tax-free  spinoff under Section 355 of the Code,  such  stockholder
would be  individually  liable for all tax liability  resulting  therefrom.  See
"Certain Federal Income Tax Consequences" for a summary of such tax liability.

LIMITED FINANCIAL RESOURCES

               The  business of AHC has not  generated  significant  revenues or
realized  a profit to date and has  operated  and is  expected  to  continue  to
operate  at a loss  for  the  foreseeable  future.  AHC  has  historically  been
dependent on Axion for funding, and AHC's future development is dependent on its
ability to obtain  sufficient  funding.  AHC has expended  and will  continue to
expend substantial funds in the development of its cancer-specific  managed care
service business.  AHC may seek additional  funding for these purposes through a
combination of new collaborative arrangements,  strategic alliances,  additional
equity or debt financings or from other sources.  There can be no assurance that
such additional funds will be available on acceptable  terms, if at all. Even if
available,  the cost of funds may  result in  substantial  dilution  to  current
stockholders.  If adequate funds are not available from operations or additional
sources of financings, AHC's business, operating results and financial condition
could be  materially  and  adversely  affected.  See  "--Dividends  and Dividend
Policy" and  "Management's  Discussion  and Analysis of Financial  Condition and
Results of Operations".

ONCARE PREFERRED STOCK

               After the Distribution,  AHC will hold 2,700,000 shares of OnCare
Preferred Stock, which is nonvoting,  nonconvertible and mandatorily redeemable,
at a redemption  price of $5.00 per share, at the earliest of December 31, 2000,
an   underwritten   public   offering  of  OnCare  common  stock,  a  merger  or
consolidation of OnCare with or into another corporation,  or the sale of all or
substantially all of OnCare's assets to another person or entity. As of the date
hereof,  OnCare does not have sufficient resources to fund the redemption of the
2,700,000  shares of  OnCare  Preferred  Stock  held by AHC,  and the  mandatory
redemption  date of the  OnCare  Preferred  Stock  was  recently  extended  from
December 31, 1996 to December 31, 2000. Prior to the Time of  Contribution,  AHC
will  agree  that it will  not  sell,  offer  to sell,  pledge,  hypothecate  or
otherwise  transfer or dispose of any OnCare Preferred  Stock. In addition,  AHC
will agree to waive its rights to receive any dividends on the OnCare  Preferred
Stock.  There can be no  assurance  that  OnCare will be able to redeem all or a
portion of the 2,700,000 shares held by AHC on December 31, 2000 or at any other
time in the future.  If OnCare is unable to redeem the shares held by AHC, AHC's
business,  financial  condition  and results of  operations  could be  adversely
affected.

DEPENDENCE UPON KEY PERSONNEL; POTENTIAL CONFLICTS OF INTEREST WITH ONCARE

               AHC's  future  success  depends  in  significant  part  upon  the
continued service of its key senior management personnel,  none of whom is bound
by an employment agreement.  AHC's future success also depends on its continuing
ability to attract and retain highly qualified  personnel.  Competition for such
personnel is intense,  and there can be no assurance that AHC can retain its key
employees or that it can attract,  assimilate  or retain other highly  qualified
personnel in the future. Failure to attract and retain such personnel could have
a material adverse effect upon AHC's business,  financial  condition and results
of operations.  Additions of new personnel and departures of existing personnel,
particularly in key positions, can result in staffing adjustments and departures
of existing  personnel,  which could have a material  adverse  effect upon AHC's
business, financial condition and results of operations.

               Certain AHC officers  also hold  management  positions in OnCare.
There can be no  assurance  that the  responsibilities  of such persons in their
capacity as  officers  of OnCare will not result in a conflict of interest  with
    

                                       14


 
<PAGE>
 

<PAGE>
   
their  duties as AHC  officers.  Additional  factors  may also cause a potential
conflict  of  interest  between  AHC and  OnCare,  including  the fact  that AHC
currently  conducts  business with OnCare,  AHC is a substantial  stockholder in
OnCare and AHC and OnCare have a substantially overlapping stockholder base. The
recent extension of the mandatory  redemption date of the OnCare Preferred Stock
was  agreed  to by Axion  without  additional  consideration  from  OnCare.  See
"Management--Officers and Directors". See "The Company--Employees" and "--Future
Conduct of the Business".

RELATIONSHIP WITH BMS; RESTRICTIONS ON AHC

               AHC has agreed,  pursuant to its  Noncompetition  Agreement  with
BMS, for a period of two years after the  Effective  Time,  not to engage in, or
compete with BMS with respect to, the  distribution of oncology drugs,  supplies
or  biologics  to the  Customer  Group or  automated  drug  dispensing  business
anywhere in the United States. AHC has entered into the AHC Supply Agreement and
OnCare  has  entered  into the  OnCare  Supply  Agreement  each of which will be
effective at the Closing Date and which provide that AHC and OnCare will use the
Partnership as their exclusive provider of oncology pharmaceutical products. AHC
has entered into the AHC  Medstation  Agreement  and OnCare has entered into the
OnCare Medstation  Agreement each of which will be effective at the Closing Date
and which  will  provide  that AHC and OnCare  will use OPUS as their  exclusive
provider of oncology  drug  dispensing  machines and that OPUS will provide such
machines  at the lowest  price it offers to a specified  category of  purchasers
(subject to certain conditions). In addition,  following the Merger, AHC and the
Surviving  Corporation  will  enter  into the  Transitional  Services  Agreement
pursuant  to  which  AHC and the  Surviving  Corporation  will  provide  certain
services to each other. There can be no assurance that the restrictions  imposed
on AHC by the agreements described above will not have a material adverse effect
on  AHC's  business,   financial   condition  and  results  of  operation.   See
"Relationship with BMS--License Agreement", "--Transitional Services Agreement",
"--The  Noncompetition  Agreements" and "--AHC Supply  Agreement;  OnCare Supply
Agreement; AHC Medstation Agreement; OnCare Medstation Agreement".

RELIANCE ON TRANSITIONAL SERVICES AGREEMENT

               The Transitional  Services Agreement provides that AHC will agree
to provide to the Surviving  Corporation  certain services,  including financial
and information systems services,  and that the Surviving Corporation will agree
to  provide to AHC  certain  services,  including  certain  information  systems
services and clinical trial logistics  support.  The services provided under the
Transitional  Services  Agreement will be performed for a period of three months
from the Effective  Time with  renewals of one month upon the mutual  consent of
the parties  with such  renewals  not to exceed an  aggregate of three months in
addition to the original term. There can be no assurance that the termination of
the services provided by the Surviving  Corporation pursuant to the Transitional
Services  Agreement will not have a material  adverse effect on AHC's  business,
financial  condition and results of operation.  See "Relationship  with BMS--The
Transitional Services Agreement".

RISK OF REGISTRATION UNDER INVESTMENT COMPANY ACT OF 1940

               Because AHC  currently  owns the OnCare  Preferred  Stock,  which
constitutes a significant portion of AHC's total assets, there is a risk that it
could be characterized as an investment company under the Investment Company Act
of 1940, as amended (the "Investment Company Act"). AHC believes that it is not,
and after giving effect to the Merger, the Distribution and related transactions
will not be, an  investment  company and intends to continue  its  business  and
conduct its  operations so as not to become  subject to the  Investment  Company
Act.  If the  Commission  or its staff were to take the  position,  or if it was
otherwise asserted,  that AHC was an investment company,  AHC could be required,
among other things,  (i) to liquidate its holdings of OnCare  Preferred Stock to
avoid being required to register as an investment company or (ii) to register as
an investment  company.  If AHC were required to register  under the  Investment
Company  Act,  it would be subject to  substantive  regulation  with  respect to
capital structure,  operations,  transactions with affiliates and other matters.
If AHC were found to be an investment  company but was not registered  under the
Investment  Company  Act,  AHC would be  prohibited  from,  among other  things,
engaging in  interstate  commerce or  conducting  public  offerings or, could be
subject to monetary  penalties and injunctive relief in an action brought by the
Commission,  and might be unable to enforce  contracts with
    


                                       15


 
<PAGE>
 

<PAGE>
   
third parties.  As a result, any determination that AHC is an investment company
would have a material adverse effect on AHC.

REPAYMENT OF LOANS MADE TO CURRENT HOLDERS OF AXION OPTIONS

               Pursuant  to the  Merger  Agreement  all  Axion  Options  will be
exercised or canceled. Axion will make loans totaling approximately $6.5 million
(the "Employee Loans") to approximately 91 holders of Axion Options who must use
the  proceeds  to  exercise  such  Axion  Options.  Such loans may or may not be
secured.  The obligations of the holders of Axion Options who receive such loans
will become  obligations to AHC instead of Axion. There can be no assurance that
holders of Axion  Options who receive  such loans will repay any or all of their
obligations to AHC following the Merger.  In fact, some holders of Axion Options
receiving such loans will not be employees of AHC following the Effective  Time,
which may reduce  the  ability  of AHC to obtain  repayment.  Failure to receive
repayment of such loans could have a material  adverse effect on AHC's business,
financial condition and results of operation.

COMPETITION

               The   environment   in  which  AHC  will   operate  is  intensely
competitive.  AHC will  have a number  of  current  and  potential  competitors,
including  pharmaceutical and biotechnology  companies,  insurance companies and
information  service companies,  a significant number of which have or will have
substantially  greater financial and human resources  capabilities than AHC. AHC
expects  additional  competition from other established and emerging  companies,
particularly  if the  national  trend  towards  managed care  continues  and the
community of office-based oncologists continues to develop and expand. Increased
competition could result in price reductions, reduced margins and loss of market
share,  any of which could  materially  and  adversely  affect  AHC's  business,
financial  condition and results of  operations.  There can be no assurance that
AHC will be able to compete  successfully  against current or future competitors
or that  competitive  pressures  faced by AHC will not  materially and adversely
affect AHC's business, financial condition and results of operations.

DEPENDENCE ON THIRD-PARTY SERVICE PROVIDERS

               AHC  is  dependent  upon  third  parties  for  clinically-derived
treatment data and information on developing  drugs and drug therapies.  Many of
the drug  manufacturers,  insurance  companies,  research  centers and  oncology
practices that supply information to AHC are current or potential competitors of
AHC. There can be no assurance that these third-party service providers will not
cease to provide  information  to AHC,  increase  the prices they charge AHC, or
enter  into  direct  competition  with AHC.  AHC has no  continuing  contractual
arrangement with many of the third parties that supply it with  information.  To
date AHC has been able to obtain adequate information. There can be no assurance
that AHC will be able to obtain adequate information in the future. In the event
that AHC's third-party  service  providers were unwilling to continue  providing
such  services  to AHC,  AHC's  business,  financial  condition  and  results of
operations would be materially and adversely affected.

DIVIDENDS AND DIVIDEND POLICY

               AHC does not  anticipate  declaring and paying cash  dividends on
the AHC  Preferred  Stock at any time in the  foreseeable  future.  The decision
whether to apply legally  available funds to the payment of dividends on the AHC
Preferred  Stock will be made by the AHC Board from time to time in the exercise
of its business judgment, taking into account, among other things, AHC's results
of  operations  and  financial  condition  and any  then  existing  or  proposed
commitments for the use of AHC's available funds. The Indemnification  Agreement
provides,  however,  that for a period of six years following the Effective Date
(subject  to  extension  in  certain  circumstances),  AHC may not  declare  any
dividends on AHC's  capital  stock.  See  "--Limited  Financial  Resources"  and
"Indemnification Arrangements--Terms of the Indemnification Agreement".

               In  addition,  AHC  may  in the  future  issue  debt  securities,
preferred stock or enter into loan or other agreements that restrict the payment
of dividends on and  repurchases of AHC's capital stock.  See  "--Business to be
Conducted by AHC; Limited Operating  History;  History of Losses" and "--Limited
Financial Resources".

ABSENCE OF TRADING MARKET; RESTRICTIONS ON RESALE
   
               There is no existing  trading market for AHC Preferred Stock. AHC
has not sought and does not intend to apply for listing of AHC  Preferred  Stock
on a securities  exchange or seek  approval for  quotation  through an automated
quotation system. There can be no assurance that any trading market will develop
for AHC  Preferred  Stock,  and the  Restated AHC  Certificate  and Restated AHC
Bylaws provide for the same  restrictions on transfer to be placed on AHC Common
Stock once such stock is issued. In addition,  the Restated AHC Certificate will
provide  for  various  restrictions  on transfer  of AHC  Preferred  Stock.  The
certificates  evidencing the AHC Preferred Stock will bear a legend referring to
these restrictions on transfer. See "Trading of AHC Preferred Stock".

FUTURE ACQUISITIONS; DILUTION

               AHC  may in  the  future  pursue  acquisitions  of  complementary
businesses.  Future  acquisitions  by AHC may result in  dilutive  issuances  of
equity  securities  and the  incurrence  of  additional  debt  and  amortization
expenses  related  to  goodwill  and  intangible  assets,  any  of  which  could
materially  adversely affect AHC's business,  financial condition and results of
operations.   In  addition,   acquisitions  involve  numerous  risks,  including
difficulties in the assimilation of the operations of the acquired company,  the
diversion of  management's  attention  from other  business  concerns,  risks of
entering markets in which AHC has limited or no prior direct  experience and the
potential  loss of key employees of the acquired  company.  The  Indemnification
Agreement limits the ability of AHC and the 81% AHC Subsidiaries for a period of
six  years   following  the  Closing  Date  (subject  to  extension  in  certain
circumstances) to engage in certain transactions, including, but not limited to,
the  following:  liquidations,  dissolutions,  winding up of  affairs,  mergers,
consolidations, sales, leases, transfers,  recapitalizations and restructurings.
There are currently no  negotiations,  commitments or agreements with respect to
any acquisition. See "Indemnification  Arrangements-Terms of the Indemnification
Agreement-Covenants."

RISKS ASSOCIATED WITH UNCERTAIN HEALTH CARE ENVIRONMENT

               The health  care  industry  in the  United  States  continues  to
undergo fundamental change. There currently are a number of proposals for reform
of  the  health  care  system,   including  changes  to  Medicare  and  Medicaid
reimbursement.  Due to uncertainties  regarding the ultimate  features of reform
initiatives and their enactment and implementation, AHC cannot predict which, if
any, of such proposals will be adopted,  when they may be adopted or what impact
they may have on AHC.  The  actual  announcement  of  reform  proposals  and the
investment community's reaction to such proposals,  announcements by competitors
and payers of their  strategies  to respond to reform  initiatives  and  general
industry  conditions  are  likely  to  produce  volatility  in the  cancer  care
management services market and could have a material adverse effect on the value
of AHC Preferred Stock.

GOVERNMENT REGULATION

               AHC's  activities  are  regulated  under  federal and state laws.
These  laws and  regulations  are broad in scope  and are  subject  to  frequent
modification and reinterpretation.  Any application of such laws and regulations
by a governmental  authority to AHC's  practices so as to require  alteration of
those  practices  could  have an  adverse  effect on AHC's  business,  operating
results and financial condition. There can be no assurance that AHC's activities
will be determined to be in compliance  with  applicable  laws and  regulations.
Noncompliance  with such laws and regulations could materially  adversely affect
AHC's business, financial condition and results of operations.

SUBSTANTIAL STOCKHOLDERS; CERTAIN PROVISIONS OF THE RESTATED AHC CERTIFICATE

               Immediately  following the Distribution,  directors and executive
officers of AHC will  beneficially  own shares of AHC Preferred Stock (including
any shares of Axion Common Stock issued in  connection  with the  conversion  of
Axion  Preferred  Stock to Axion Common Stock and the exercise of Axion Options,
in each case in connection  with the  consummation  of the Merger)  representing
over 57.2% of the voting power of AHC's then outstanding voting securities.  See
"Security Ownership of Certain Beneficial Owners".

               Certain  provisions  of the  Restated  AHC  Certificate  and  the
Restated  AHC  Bylaws may be deemed to have the  effect of making  difficult  an
acquisition  of control of AHC in a  transaction  not approved by the AHC Board.
These  provisions  include  the  ability  of the AHC  Board to issue  shares  of
preferred stock in one or more series without further  authorization  of the AHC
stockholders  and certain other provisions  described under  "Description of AHC
Capital Stock". Many of these provisions are also present in Axion's certificate
of incorporation  and bylaws as currently in effect,  and generally are designed
to permit AHC to develop its businesses and foster its long-term  growth without
the disruption caused by the threat of a takeover not deemed by the AHC Board to
be in the best interests of AHC and its stockholders.  These provisions may also
have the effect of  discouraging  a third  party from  making a tender  offer or
otherwise  attempting  to obtain  control of AHC even though such a  transaction
might be economically  beneficial to AHC and its stockholders.  See "Description
of AHC Capital  Stock--Description  of Certain  Certificate of Incorporation and
Bylaw Provisions".


                                        THE COMPANY

GENERAL

               AHC was  organized  in the  State of  Delaware  in 1994 as OnCare
Health Inc. In December, 1995, AHC changed its name to Axion HealthCare Inc. AHC
is currently a direct wholly owned subsidiary of Axion and immediately  prior to
the Time of Distribution, OPUS Sub will be a wholly owned subsidiary of AHC.

               AHC conducts the AHC Business, which AHC anticipates will consist
of  providing  cancer-specific  managed  care services to cancer care payers and
providers. AHC will provide services and information tools specifically designed
to assist in better managing  cancer care from both a clinical  quality and cost
standpoint.  AHC has derived  limited  revenues to date from such services.  The
OPUS  Matrix  Business   consists  of  (i)  computer   software  which  provides
office-based  oncology  practices with access to drug and treatment  information
and (ii) the management  information  systems  currently used to support Axion's
businesses.  The OPUS Matrix Business has incurred losses since its inception in
1994.

               The mailing address of AHC's principal  executive offices is 1111
Bayhill Drive, Suite 125, San Bruno, California 94066.

               Set forth below is a  description  of the Acquired  Business that
will be held by AHC immediately prior to the Time of Distribution.

INDUSTRY

               AHC  believes  it is  well  positioned  to  capitalize  on a wide
spectrum of  opportunities  in the management of cancer care.  Cancer care costs
are  growing  at an annual  rate of over 10%.  In 1990,  $35  billion  was spent
directly  on  cancer  care.  These  costs  exceeded  $50  billion  in 1995.  The
traditional approach to managing disease has been to focus mainly on episodes of
care.  Payers  have  attempted  to minimize  expenses  through  individual  cost
components  such  as   hospitalization,   professional   services,   home  care,
pharmaceuticals and laboratories.  This approach has been generally unsuccessful
due to cost shifting by providers.  AHC has created and is continuing to develop
a set of multidimensional tools for the management of cancer care. This approach
relies on scientifically and clinically derived consensus  treatment  guidelines
as well as automated  decision  support systems and software in development that
permit the capture  and  analysis of  outcomes  data,  both within a  particular
oncology practice and aggregated from multiple oncology practices.

THE AHC BUSINESS

               AHC expects that its principal business will consist of providing
cancer-specific  managed care services to cancer care payers and providers  (the
"AHC  Business").  The AHC  Business  has  generated  limited  revenues  and has
incurred  losses since AHC's  formation in 1994.  AHC was formed to carry on the
clinical  studies  programs  which  Axion  began  in 1987  and to  continue  the
development of oncology disease  management  programs
    


                                       18

<PAGE>
   
arising from such clinical studies  programs.  This clinical  studies  activity,
which AHC continues to the present, consists of coordinating clinical studies of
both   emerging  and  existing   cancer  drugs  and   treatments   developed  by
pharmaceutical  and biotechnology  companies.  Depending on the particular item,
AHC can help develop the  parameters  of a study,  negotiate  contracts,  act as
project  manager,  provide  logistical  support  (such as  ordering,  receiving,
tracking  and  disbursing  drug  shipments,  and tracking  patient  sign-ups and
responses),  receive and disburse  payments,  collect and analyze the data,  and
prepare a report of the results.  AHC derives  substantially all of its revenues
from sales to drug companies.

               The  information  and  relationships  developed  in the  clinical
studies  activity have resulted in the provision of other  services,  largely to
office-based oncologists,  including reimbursement assistance, assistance in the
preparation of Food and Drug  Administration  applications,  and  development of
practice  management  and decision  support  software tools through OPUS Matrix.
Moreover,  AHC's knowledge and experience have enabled it to develop cancer drug
protocols and treatment  guidelines that are designed to serve as integral parts
of its disease  management  program.  In  connection  with its clinical  studies
activity,  AHC  anticipates  that it will  contract with payers and providers to
manage  the  delivery  of  cancer  care,  except in  markets  where  OnCare  has
operations.  Where OnCare has operations,  AHC anticipates that it will contract
exclusively  on behalf of OnCare using  OnCare's  network of physicians  through
which  cancer care is provided  using the  protocols  and  guidelines  described
above, and the computer resources  described below, all with a view to providing
the highest quality, cost-effective cancer treatment. An arrangement exists, and
will  continue  to exist  following  the  Distribution,  between  AHC and OnCare
whereby AHC provides certain corporate,  administrative and management services,
including use of the software used in the OPUS Matrix Business (the "OPUS Matrix
Software"), to OnCare, OnCare pays AHC for all services rendered by AHC pursuant
to a fee schedule,  and OnCare provides AHC access, on a nonexclusive  basis, to
data obtained through its use of the OPUS Matrix Software.

OPUS MATRIX BUSINESS

               The OPUS Matrix Business  consists of (i) computer software which
provides  office  based  oncology  practices  with access to drug and  treatment
information  and (ii)  the  management  information  systems  currently  used to
support Axion's  businesses.  The OPUS Matrix Business has incurred losses since
its  inception  in 1994.  The OPUS Matrix  Business  software  and systems  were
specifically designed as a computer tool to operationalize treatment guidelines,
capture specific outcomes information,  and automate the generation of treatment
plans and clinical documentation at the point-of-care.  The OPUS Matrix Business
software and systems  include drug  information  (licensed from First  DataBank)
which  allows  users to look up  specific  information  about the drugs that are
ordered,  as well as providing the information  base for the system's  automatic
checking of drug interactions and allergies.

AHC'S STRATEGY

               AHC's strategy consists of the rational organization of the means
to deliver care, including medical oncologists,  radiation oncologists, surgical
oncologists,  hospitals,  home care,  laboratory  services and hospice  care. By
accepting  financial  risk for the  total  population  of cancer  patients,  AHC
believes  that it is possible to remove the economic  incentive  for  individual
providers to increase  reimbursement by inappropriately  overemphasizing any one
aspect of care.  Through this integrated  approach,  AHC believes that it may be
able to  effect  significant  savings  to  payers  and at the same  time  assure
providers of adequate payment for delivered services. AHC's strategy encompasses
a region-by-region,  or  market-by-market,  approach in partnerships with payers
and providers.  In those markets where OnCare has  operations,  AHC  anticipates
that it will contract exclusively on behalf of OnCare.

               AHC believes that payers,  HMOs,  self-insured  employers and IPA
can derive the following  benefits from  contracting with AHC for the total care
of cancer patients:

                    the delivery of  consistent  quality care to their  patients
                    through  the  application  of a  wide  spectrum  of  disease
                    management tools;
    
                                       19


 
<PAGE>
 

<PAGE>
   
                    a  standard,  quality-driven,   cost-effective  approach  to
                    cancer  care  which  systematically  eliminates  unnecessary
                    costs; and

                    predictable costs

AHC's  strategy is to share risk with payers and providers,  purchase  ancillary
services on a contract  basis and in general to realign  economic  incentives to
promote rational utilization of medical and financial resources.

FUTURE CONDUCT OF THE BUSINESS

               In  addition  to  the  assets  and  interests   described  above,
following  the  Distribution  AHC intends to continue to consider  acquisitions,
strategic  alliances  and joint  ventures in an effort to  increase  stockholder
value.  The  management  of AHC  following  the  Distribution  is expected to be
substantially the same as the management of AHC prior to the Distribution.

COMPETITION

               AHC will  have a number of  current  and  potential  competitors,
including  pharmaceutical and biotechnology  companies,  insurance companies and
information  service companies,  a significant number of which have or will have
substantially  greater  financial and human resource  capabilities than AHC. See
"Special Factors--Competition".

RELATIONSHIP WITH ONCARE

               AHC's  relationship  with OnCare may result in certain  potential
conflicts   between  the   business   of  the  two   companies.   See   "Special
Factors--Dependence  Upon Key  Personnel;  Potential  Conflicts of Interest with
OnCare".

EMPLOYEES

               It is anticipated  that immediately  following the  Distribution,
AHC will  employ  approximately  25  persons.  Certain  AHC  officers  also hold
management  positions  in  OnCare.  See  "Special   Factors--Dependence  on  Key
Personnel; Potential Conflicts of Interests with OnCare".

PROPERTIES

               The Partnership currently leases approximately 18,600 square feet
of office space in a building in South San Francisco,  California. This facility
is  leased  through  October  2001,  and  will  continue  to be  leased  by  the
Partnership after the Merger.

               AHC currently  occupies office space at 1111 Bayhill Drive, Suite
125, San Bruno,  California.  This office space is leased from OnCare, which has
an informal sublease arrangement with AHC. Such office space will continue to be
leased by AHC from OnCare after the Merger.

                                        THE MERGER

               This  section  of the  Information  Statement  describes  certain
aspects of the  proposed  Merger.  To the  extent  that it relates to the Merger
Agreement,  the  following  description  does not purport to be complete  and is
qualified  in its  entirety  by  reference  to the  Merger  Agreement,  which is
attached  as  Appendix  A  to  the  Proxy  Statement/Prospectus  to  which  this
Information  Statement is attached as Appendix G and is  incorporated  herein by
reference. As used in this Information Statement,  the "Retained Company" or the
"Retained  Companies",  as the  case  may be,  means  Axion,  together  with its
subsidiaries,  OTNC, OPUS and the Partnership,  which  collectively will own and
conduct the Retained Business at the Effective Time. ALL AXION  STOCKHOLDERS ARE
URGED TO READ THE MERGER AGREEMENT IN ITS ENTIRETY.
    
               If the Merger  Agreement  is  approved  and  adopted by the Axion
stockholders and the other conditions to the Merger are satisfied or waived,  at
the  Effective  Time BMS Sub will be merged with and into Axion (which will then
hold only the Retained  Business) with Axion as the Surviving  Corporation,  and
the separate existence of BMS Sub will cease.

TERMS OF THE MERGER AGREEMENT
   
               Pursuant  to the Merger  Agreement,  at the  Effective  Time each
issued and  outstanding  share of Axion  Common  Stock (other than any shares of
Axion  Common  Stock  owned by Axion  or any  subsidiary  of Axion or BMS or any
wholly owned subsidiary of BMS and any Dissenting Shares) will be converted into
the right to  receive  the  Conversion  Number of fully  paid and  nonassessable
shares of BMS Common Stock (the "Merger Consideration"). The "Conversion Number"
will be equal to the quotient of (a)(i) $86 million  divided by (ii) the Average
Value of BMS Common  Stock  divided by (b) the number of shares of Axion  Common
Stock outstanding immediately prior to the Effective Time (calculated on a fully
diluted basis  assuming  that each share of Axion  Preferred  Stock  outstanding
immediately  prior to the Effective Time has been  converted in accordance  with
its terms into one share of Axion Common Stock and all Axion Options outstanding
immediately prior to the Effective Time have been exercised or canceled and that
the related subject shares (other than any subject shares related to any portion
of any Axion Option that shall have been  canceled and not  exercised)  of Axion
Common Stock are outstanding  (collectively,  the "Diluted Share  Assumption")).
The term  "Average  Value of BMS  Common  Stock"  means an  amount  equal to the
average of the per share  closing  prices of BMS Common Stock as reported on the
NYSE Tape for the 10 consecutive full NYSE trading days ending on the fifth full
NYSE trading day immediately  preceding the Effective Time; provided that (A) if
the BMS Board declares a cash dividend on the  outstanding  shares of BMS Common
Stock having a record date after the Effective Time but an  ex-dividend  Ex-Date
that occurs  during the  averaging  period,  then for purposes of computing  the
Average  Value of BMS Common  Stock,  the  closing  price on the Ex-Date and any
trading day in the averaging period after the Ex-Date will be adjusted by adding
thereto  the amount of such  dividend  and (B) if the BMS Board  declares a cash
dividend  on the  outstanding  shares of BMS Common  Stock  having a record date
before  the  Effective  Time and an Ex-Date  that  occurs  during the  averaging
period,  then for purposes of computing  the Average  Value of BMS Common Stock,
the closing  price on any  trading  day before the  Ex-Date  will be adjusted by
subtracting therefrom the amount of such dividend.  Notwithstanding  anything to
the  contrary  contained  in the Merger  Agreement,  in the event that as of the
Closing  Date the  Average  Value of BMS Common  Stock is less than the  Minimum
Price ($82.73),  then for the purposes of calculating the Merger  Consideration,
the Average  Value of BMS Common  Stock will be deemed to be the Minimum  Price,
and in the event that as of the  Closing  Date the  Average  Value of BMS Common
Stock is greater  than the  Maximum  Price  ($91.43),  then for the  purposes of
calculating the Merger Consideration, the Average Value of BMS Common Stock will
be deemed to be the Maximum  Price.  If, prior to the  Effective  Time,  the BMS
Board  declares  a stock  split,  stock  combination,  stock  dividend  or other
non-cash  distribution on the outstanding  shares of BMS Common Stock,  then the
Minimum Price and Maximum Price (and if the Ex-Date for such event occurs during
the  averaging  period,   the  Average  Value  of  BMS  Common  Stock)  will  be
appropriately  adjusted to reflect  such split,  combination,  dividend or other
distribution.


               Based on the Diluted Share  Assumption (and assuming  exercise of
all Axion Options other than the Goldberg  $10.00  Options (as defined  herein),
resulting in an aggregate of 9,970,509 shares of Axion Common
    



                                       21

Stock  outstanding),  and assuming an Average Value of BMS Common Stock equal to
$92.83 (the average per share  closing price of BMS Common Stock for the 10 full
NYSE trading days ending  September 18, 1996,  the most recent full NYSE trading
day available prior to printing this Proxy Statement/Prospectus), in which event
the  Conversion  Number  would be  calculated  based on an Average  Value of BMS
Common Stock equal to the Maximum  Price of $91.43,  (a) the  Conversion  Number
would be 0.094 and (b)  assuming a market  value of the BMS Common  Stock on the
date  received  by holders of Axion  Common  Stock in the Merger of $92.83,  the
aggregate  market  value of BMS Common  Stock to be received by holders of Axion
Common Stock in the Merger would be approximately $87 million,  or approximately
$8.73 per share of Axion  Common  Stock.  THERE CAN BE NO  ASSURANCE  THAT THESE
ASSUMPTIONS WILL BE TRUE AS OF THE EFFECTIVE TIME.

               The Average  Value of BMS Common Stock is  determined  as of five
full NYSE trading days immediately  preceding the Effective Time (which date may
be after the date of the Special  Meeting),  at which time the Average  Value of
BMS Common Stock may be less than the assumed $92.83 Average Value of BMS Common
Stock  referred to above and indeed may be less than the Minimum  Price.  If the
Average  Value of BMS Common  Stock at such time is between  the  Minimum  Price
($82.73)  and the Maximum  Price  ($91.43),  the  aggregate  market value of BMS
Common  Stock to be received by holders of Axion Common Stock in the Merger will
be $86 million, or approximately $8.63 per share of Axion Common Stock (based on
the Diluted Share  Assumption  and assuming  exercise of all Axion Options other
than the Goldberg $10.00  Options).  If the Average Value of BMS Common Stock at
such time is less than the Minimum  Price,  the  aggregate  market  value of BMS
Common  Stock to be received by holders of Axion Common Stock in the Merger will
be less, and may be substantially less, than $86 million, or approximately $8.63
per share of Axion  Common  Stock  (based on the Diluted  Share  Assumption  and
assuming  exercise of all Axion Options other than the Goldberg $10.00 Options).
The foregoing  statements in this paragraph  assume that the market value of BMS
Common Stock on the Closing Date is equal to the Average Value of the BMS Common
Stock used to calculate the Conversion Number.  However, the actual market value
of BMS  Common  Stock on the  Closing  Date may be  substantially  less than the
Average Value of BMS Common Stock used to calculate the Conversion  Number.  The
actual  aggregate  market value on the Closing Date of BMS Common Stock received
by holders of Axion  Common  Stock in the Merger  will be equal to the number of
shares of BMS Common Stock issued in the Merger  multiplied  by the market value
of the BMS Common Stock on the Closing Date.

               UNDER THE TERMS OF THE MERGER AGREEMENT,  AXION DOES NOT HAVE THE
RIGHT TO DECLINE TO  CONSUMMATE  THE MERGER  SOLELY  BECAUSE  EITHER THE AVERAGE
VALUE OF BMS COMMON STOCK USED TO CALCULATE THE  CONVERSION  NUMBER IS LESS THAN
THE MINIMUM  PRICE OR BECAUSE THE ACTUAL MARKET VALUE OF BMS COMMON STOCK ON THE
CLOSING  DATE IS LESS  THAN  THE  AVERAGE  VALUE  OF BMS  COMMON  STOCK  USED TO
CALCULATE THE CONVERSION  NUMBER.  THEREFORE,  IF THE MERGER PROPOSAL IS ADOPTED
AND APPROVED AND ALL OTHER  CONDITIONS TO THE MERGER ARE SATISFIED (OR WAIVED BY
THE  PARTY FOR  WHOSE  BENEFIT  ANY SUCH  CONDITION  EXISTS)  AT OR PRIOR TO THE
EFFECTIVE  TIME,  AXION  STOCKHOLDERS  WILL  ASSUME THE RISK OF A DECLINE IN THE
MARKET VALUE OF BMS COMMON  STOCK BELOW THE MINIMUM  PRICE AND THE RISK THAT THE
ACTUAL  MARKET  VALUE OF BMS COMMON  STOCK ON THE CLOSING  DATE IS LESS THAN THE
AVERAGE VALUE OF BMS COMMON STOCK USED TO CALCULATE THE  CONVERSION  NUMBER AND,
ACCORDINGLY,  THE RISK THAT THE AGGREGATE MARKET VALUE OF BMS COMMON STOCK TO BE
RECEIVED  BY  THE  HOLDERS  OF  AXION   COMMON  STOCK  IN  THE  MERGER  WILL  BE
SUBSTANTIALLY  LESS THAN $86 MILLION OR APPROXIMATELY  $8.63 PER SHARE (BASED ON
THE DILUTED SHARE  ASSUMPTION  AND ASSUMING  EXERCISE OF ALL AXION OPTIONS OTHER
THAN THE GOLDBERG $10.00 OPTIONS).

               In addition,  the number of assumed  outstanding  shares of Axion
Common Stock for the purpose of calculating the Conversion  Number is determined
as of immediately  prior to the Effective Time (which date may be after the date
of the Special Meeting),  at which time the actual number of outstanding  shares
of Axion Common Stock may be greater than the assumed  9,970,509 shares referred
to above.  Each share of Axion Common Stock will be converted in the Merger into
the right to receive the  Conversion  Number of shares of BMS Common Stock.  Any
increase in the actual number of outstanding  shares of Axion Common Stock as of
immediately prior to the Effective Time would result in a corresponding decrease
in the Conversion Number and, accordingly, in the number of shares of BMS Common
Stock to be received in respect of each share of Axion Common Stock. The maximum
number of shares of Axion Common Stock that may be outstanding as of immediately
prior to the Effective Time is 10,070,509 shares.

               As of the record date for determining Axion stockholders entitled
to  receive  notice of and vote at the  Special  Meeting  (the  "Record  Date"),
1,606,651  shares of Axion Common Stock were outstanding and 8,471,011 shares of
Axion Common Stock were issuable upon  conversion of the Axion  Preferred  Stock
and the exercise of Axion Options.  The approval of the Preferred Stock Proposal
by  holders  of  Axion  Preferred  Stock,  the  conversion  of each  issued  and
outstanding share of Axion Preferred Stock into one fully paid and nonassessable
share of Axion  Common  Stock  and the  exercise  or  cancelation  of all  Axion
Options,  in each case prior to the Effective  Time, are each  conditions to the
Merger.  Michael D.  Goldberg,  the  President,  Chief  Executive  Officer and a
director of Axion, AHC and OnCare,  has advised Axion that he does not intend to
exercise his options to purchase 100,000 shares of Axion Common Stock at a price
of $10.00 per share (the "Goldberg $10.00 Options").  Accordingly,  the Goldberg
$10.00  Options will be canceled  prior to the Effective  Time, and assuming the
conversion of each issued and outstanding share of Axion Preferred Stock and the
exercise of all Axion  Options  other than the Goldberg  $10.00  Options,  it is
anticipated  that there will be  approximately  9,970,509 shares of Axion Common
Stock issued and outstanding on the Closing Date.

               On the  Closing  Date,  a portion of the BMS  Common  Stock to be
received by Former Axion Stockholders in the Merger,  with a value of $5,000,000
(the "Escrowed Shares"), will be placed in escrow on behalf of such Former Axion
Stockholders,  and AHC will be required to place  Escrowed Cash in the amount of
$5  million  in  escrow to  secure  certain  obligations  of such  Former  Axion
Stockholders  and AHC and  certain  of its  subsidiaries  to  indemnify  the BMS
Indemnified  Parties  under  the  Indemnification  Agreement,  the  Tax  Matters
Agreement and the Escrow Agreement (each as defined herein). The indemnification
obligations of each of the Former Axion Stockholders  under the  Indemnification
Agreement  will be limited in amount to the Escrowed  Shares,  except in certain
circumstances  involving  fraud,  intentional  misrepresentation  or intentional
breach of a covenant by any such Former Axion Stockholder.  The  indemnification
obligations of AHC and the 81% AHC Subsidiaries will not be limited in amount to
the Escrowed Cash. There can be no assurance as to whether all or any portion of
such Escrowed Shares will  eventually be released to such  Stockholders or as to
whether all or any portion of such Escrowed Cash will  eventually be released to
AHC or that the indemnification obligations of AHC and its subsidiaries will not
exceed the Escrowed  Cash.  There can be no assurance that the failure to obtain
the  release  of all or a portion of such  Escrowed  Cash or the  incurrence  of
indemnification  obligations  in  excess  of the  Escrowed  Cash will not have a
material   adverse   effect  on  AHC.  See   "Special   Factors--Indemnification
Obligations of the Former Axion Stockholders,  AHC and the 81% AHC Subsidiaries"
and  "Indemnification  Arrangements--Terms  of the  Indemnification  Agreement",
"--Terms of the Tax Matters Agreement" and "--Terms of the Escrow Agreement".

        FRACTIONAL SHARES.

               No  fractional  shares of BMS Common  Stock will be issued in the
Merger.  The Merger Agreement provides that each Axion stockholder who otherwise
would have been  entitled to receive a fraction  of a share of BMS Common  Stock
will receive,  in lieu thereof,  cash (without interest) in an amount,  less the
amount of any  withholding  taxes which may be required  thereon,  equal to such
fractional  part of a share of BMS  Common  Stock  multiplied  by the per  share
closing  price of BMS Common Stock as reported on the NYSE Tape on the full NYSE
trading day immediately preceding the Closing Date.

        EFFECTIVE TIME; CLOSING.

               The Merger  will become  effective  and the  Effective  Time will
occur  immediately upon the filing of a certificate of merger (the  "Certificate
of Merger") with the Delaware  Secretary of State or at such time  thereafter as
is provided in the Certificate of Merger. The Merger Agreement provides that the
closing (the  "Closing") of the Merger will take place on a date to be specified
by the  parties  which date will be no later than the first  business  day after
satisfaction  (or  waiver  by the party for  whose  benefit  any such  condition
exists) of the conditions to the Merger Agreement, unless another date is agreed
to in writing by BMS, BMS Sub and Axion.

        DISTRIBUTION OF MERGER CONSIDERATION; EXCHANGE OF SHARE CERTIFICATES.

               At or  immediately  after the  Closing  Date,  BMS will send each
Former Axion  Stockholder a letter (the "Letter of Transmittal")  notifying such
stockholder of the consummation of the Merger and setting forth instructions for
the surrender of  certificates  (the  "Certificates")  that before the Effective
Time  represented  Axion Common  Stock.  Promptly  after receipt by the Exchange
Agent of any  Certificates  surrendered in accordance with the  instructions set
forth in the Letter of  Transmittal,  the Exchange Agent will  distribute to the
Former Axion Stockholder  entitled thereto the certificates  representing  whole
shares  of BMS  Common  Stock  and a check in lieu of  fractional  shares of BMS
Common  Stock into which the shares of Axion  Common  Stock  represented  by the
surrendered  Certificates  were  converted in the Merger.  The new  certificates
shall not include the number of  Escrowed  Shares  deemed to have been placed in
escrow by such Former Axion Stockholder. AXION STOCKHOLDERS ARE REQUESTED NOT TO
SURRENDER THEIR  CERTIFICATES  REPRESENTING  OUTSTANDING  SHARES OF AXION COMMON
STOCK FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL FROM BMS.
   
               Execution  and  delivery  of the  Letter of  Transmittal  by each
Former  Axion  Stockholder  will  result in each such Former  Axion  Stockholder
irrevocably  appointing  AHC as  his/her  or its agent and  attorney-in-fact  to
execute and  deliver on such  Former  Axion  Stockholder's  behalf,  and thereby
result in each such Former Axion  Stockholder  becoming a party to and bound by,
the Indemnification  Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution  and  delivery  of  the  Letter  of  Transmittal  will  result  in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder   that  may  be  necessary  in  connection  with  the   transactions
contemplated by such  agreements,  including to give and receive notices on each
such Former Axion  Stockholder's  behalf and to represent each such Former Axion
Stockholder  with  respect to any  matter,  suit,  claim,  action or  proceeding
arising  with  respect  to any  transaction  contemplated  by  such  agreements,
including the defense,  appeal or settlement of any claim,  action or proceeding
for which each such Former Axion  Stockholder  may be obligated to indemnify any
person  pursuant  to  such  agreements  or may be  entitled  to  indemnification
pursuant to such  agreements  or which may be brought by BMS  against  each such
Former Axion Stockholder to enforce such indemnity; and will result in each such
Former Axion Stockholder ratifying and confirming any action taken by AHC in the
exercise  of  the  power  of  attorney  granted  thereby.  See  "Indemnification
Arrangements--Terms  of the  Indemnification  Agreement",  "--Terms  of the  Tax
Matters Agreement" and "--Terms of the Escrow Agreement".  Such agreements will,
among other things,  subject each such Former Axion  Stockholder  as well as AHC
and certain of its subsidiaries to certain indemnity  obligations to BMS and its
subsidiaries  and provide for the Escrowed  Shares and the  Escrowed  Cash to be
placed    in    escrow   to   secure    these    obligations.    See    "Special
Factors--Indemnification  Obligations of the Former Axion Stockholders,  AHC and
the 81% AHC Subsidiaries".
    

        STOCK EXCHANGE LISTING.

               BMS has agreed in the Merger Agreement to use its reasonable best
efforts  to cause the  shares of BMS  Common  Stock  issued in the  Merger to be
approved for listing on the NYSE, subject to official notice of issuance,  prior
to the Closing Date.  Such approval for listing is a condition to the obligation
of each of BMS, BMS Sub and Axion to consummate the Merger.
   
        CONDITIONS.

               The Merger Agreement  provides that the respective  obligation of
each party to effect the Merger is subject to certain conditions,  including the
approval of the Merger Proposal by the  stockholders  of Axion,  the approval of
the proposal to convert,  immediately  following the  Distribution  Record Date,
each issued and  outstanding  share of Axion Preferred Stock into one fully paid
and  nonassessable  share of Axion  Common  Stock by holders of Axion  Preferred
Stock,  the  receipt  and  reaffirmation  of  opinions  with  respect to the tax
consequences of the Merger and the Distribution,  respectively,  consummation of
the Contributions and the Distribution,  the absence of certain material adverse
changes,  the receipt of certain  regulatory  approvals and, in the case of BMS,
the exercise or cancelation of all outstanding Axion Options,  the conversion of
all shares of Axion  Preferred  Stock into  shares of

Axion Common  Stock,  the absence of Axion  indebtedness  in excess of specified
levels and the absence of Dissenting Shares.

        TERMINATION.

               The Merger  Agreement  may be terminated at any time prior to the
Effective  Time,  whether  before or after  approval  of  matters  presented  in
connection with the Merger by the  stockholders of Axion:  (a) by mutual written
consent of BMS,  BMS Sub and Axion;  (b) by either BMS or Axion:  (i) if, upon a
vote at the Special Meeting or any adjournment thereof, any required approval of
the stockholders of Axion shall not have been obtained; (ii) if the Merger shall
not have been  consummated on or before October 31, 1996,  unless the failure to
consummate  the  Merger is the  result of a wilful  and  material  breach of the
Merger  Agreement  by the party  seeking  to  terminate  the  Merger  Agreement;
provided,  however,  that the passage of such period will be tolled for any part
thereof (but in no event  beyond  December 31, 1996) during which any party will
be subject to a non-final order, decree, ruling or action restraining, enjoining
or  otherwise  prohibiting  the  consummation  of the  Merger or the  calling or
holding of the Special Meeting;  or (iii) if any governmental  entity shall have
issued an  order,  decree  or  ruling  or taken  any  other  action  permanently
enjoining,  restraining  or  otherwise  prohibiting  the Merger and such  order,
decree, ruling or other action will have become final and nonappealable;  (c) by
Axion if BMS or BMS Sub shall have failed to comply in any material respect with
any of the covenants or agreements  contained in the Merger  Agreement or any of
the other Documents to be performed by BMS or BMS Sub at or prior to the time of
termination,  which  breach  will not have been cured  within 30 days  following
written notice of such breach; or (d) by BMS if Axion or any of its subsidiaries
shall have failed to comply in any material respect with any of the covenants or
agreements  contained in the Merger Agreement or any Document to be performed by
Axion or any of its  subsidiaries at or prior to the time of termination,  which
breach shall not have been cured within 30 days following written notice of such
breach.

The Merger Agreement provides that (except as provided below) whether or not the
Merger  is  consummated,   all  out-of-pocket  fees  and  expenses  incurred  in

        ACCOUNTING TREATMENT.

               The  Merger  will be  accounted  for by BMS as a  "purchase"  for
financial  accounting  purposes in accordance with generally accepted accounting
principles  ("GAAP")  whereby the purchase price will be allocated  based on the
fair values of assets acquired and liabilities assumed.

   
                                     THE DISTRIBUTION

               This  section  of the  Information  Statement  describes  certain
aspects of the  proposed  Distribution.  To the extent  that they  relate to the
Distribution Agreement, the following descriptions do not purport to be complete
and are  qualified in their  entirety by reference  to such  agreement  which is
attached  as  Appendix  B  to  the  Proxy  Statement/Prospectus  to  which  this
Information  Statement is attached as Appendix G, and is incorporated  herein by
reference. ALL STOCKHOLDERS ARE URGED TO READ SUCH AGREEMENT IN ITS ENTIRETY.

BACKGROUND OF AND REASONS FOR THE DISTRIBUTION

               Axion's management has regularly reviewed possible strategies and
transactions to enhance Axion's  competitiveness  and to position its assets and
businesses  in a manner  that would  increase  the value of those  assets and of
Axion's businesses and operations,  thereby increasing  stockholder value. These
strategies   included  a  possible   acquisition,   joint   ventures,   internal
restructurings,  outsourcing of operational  services and  divestiture of one of
its  businesses.  For a discussion of the events  leading up to the execution of
the Merger Agreement,  see "The  Merger--Background  of the Merger" in the Proxy
Statement/Prospectus to which this Information Statement is attached as Appendix
G.

               Pursuant to the Merger Agreement and the  transactions  described
therein,  BMS will acquire the Retained Business in each case, which consists of
(i)  OTNC,  including  OTNC's  interest  in OTN,  and  (ii)  OPUS,  which at the
Effective  Time will contain only the OPUS Station  Business,  including in each
case the assets and certain of the liabilities related thereto.

               The Retained Business  constitutes the only business,  assets and
liabilities  of  Axion  that  BMS  has  agreed  to  acquire.  As a  result,  the
disposition  of the  Retained  Business  will be  effected  through  a series of
sequential transactions,  including the Contributions,  the Distribution and the
Merger, all as set forth in the Merger Agreement and the Distribution Agreement.
Prior to the Effective  Time,  the Acquired  Business will be transferred to AHC
and OPUS Sub and the AHC Preferred Stock will be distributed to the stockholders
of Axion in the Distribution.  After the Distribution and at the Effective Time,
Axion will hold the Retained Business,  so that BMS will effectively acquire the
Retained  Business in the Merger.  The purpose of this  complex  structure is to
permit the disposition of the Retained  Business in a transaction that should be
tax-free  to  Axion  and  its  stockholders  in a  transaction  in  which  Axion
stockholders   will  receive  BMS  Common  Stock  and  will  also  retain  their
proportionate  equity  interests  in the  Acquired  Business  in the form of AHC
Preferred  Stock to be received  in the  Distribution.  Accordingly,  a "reverse
spinoff"  structure was adopted pursuant to which the Acquired  Business will be
transferred to AHC and its  subsidiaries and the AHC Preferred Stock will, prior
to the Merger, be distributed to Axion stockholders in the Distribution.  In the
event Axion  stockholders do not approve the Merger,  or if the Merger Agreement
is  otherwise   terminated,   Axion   nonetheless   intends  to  consummate  the
Contributions.  See "Special  Factors--Certain  Federal Income Tax Consequences"
and "Certain Federal Income Tax Consequences".

               Although the Distribution  will not be effected unless the Merger
is approved and about to occur, the Distribution is separate from the Merger and
the AHC  Preferred  Stock to be  received by holders of Axion  Common  Stock and
Axion  Preferred  Stock in the  Distribution  does not  constitute a part of the
consideration  to be  received  by  Axion  stockholders  in  the  Merger.  Axion
stockholders  are not being  asked to  approve  the  Distribution,  which is not
subject to stockholder approval. Consummation of the Distribution is a condition
to the Merger.

TERMS OF THE DISTRIBUTION AGREEMENT

        FORMATION OF OPUS SUB

               Prior to the execution of the Distribution Agreement,  Axion will
cause the  incorporation of OPUS Sub under Delaware law, and thereafter will not
permit  OPUS  Sub to  engage  in any  business  except  as  contemplated  by the
Distribution Agreement.

        DISTRIBUTION OF THE PREFERENCE AMOUNT

               Immediately  prior to the time as of which the  Contributions are
effective  (the  "Time of  Contribution")  Axion will cause OTNC to cause OTN to
distribute to OTNC an amount equal to $13,615,147 (the "Preference  Amount"), in
full  satisfaction  of all  amounts  that may be due as of, or in respect of any
period ending on or prior to, the Closing Date to OTNC in respect of its Capital
Account Prime Rate Amount and the General Partner  Cumulative  Preference Amount
(as each such term is defined in the Partnership Agreement). Notwithstanding the
preceding  sentence,  if the Closing  Date occurs after  September  30, 1996 and
Axion shall not have used Best Closing  Efforts (as defined  below) to cause the
Closing to occur on or prior to September 30, 1996, the  Preference  Amount will
be paid  only to the  extent  of cash  and  cash  equivalents  held by OTN as of
September 30, 1996 (it being  understood that for purposes of this paragraph the
amount of cash and cash equivalents held by OTN as of September 30, 1996 will be
reduced by the amount,  if any, by which  outstanding  indebtedness for borrowed
money,  or any guaranties in respect of any  indebtedness  for borrowed money of
any third party, in respect of which OTN is obligated on September 30, 1996 will
exceed  $35,617,000).  Notwithstanding  that if OTNC  fails to use Best  Closing
Efforts it will not have received the full amount of the Preference  Amount from
OTN to which it would  otherwise have been entitled,  under the terms of the Tax
Matters Agreement AHC shall nevertheless be obligated to indemnify Axion and BMS
for any taxes with  respect to the income of OTN for all  periods  prior to June
30, 1996,  including such income that is not distributed as a Preference  Amount
to OTNC by reason of the fact that OTNC will not have used Best Closing Efforts.
"Best  Closing  Efforts"  means,  in addition to Axion not  otherwise  knowingly
taking any action to frustrate  or delay the Merger,  the  following:  (i) Axion
will have  diligently  responded to all Securities and Exchange  Commission (the
"Commission")  comments to the  Registration  Statement on Form S-4 filed by BMS
(including exhibits and amendments thereto, the "BMS Registration  Statement" or
the "Form S-4")  related to Axion or its  subsidiaries  (A) within five business
days after receipt by Axion or its counsel of any initial Commission comments to
the Form S-4 and (B) within a reasonably  prompt period under the  circumstances
after receipt by Axion or its counsel of any subsequent  Commission  comments to
the Form S-4;  (ii) in the event that the  no-action  relief  requested by Axion
from the  Commission  with respect to the  distribution  of AHC Preferred  Stock
without  registration  under the Securities Act is obtained from the Commission,
this Information  Statement will have been distributed to Axion  stockholders at
the  same  time as the  Proxy  Statement/Prospectus  to which  this  Information
Statement is attached is distributed to such Axion stockholders; and (iii) Axion
will have within two business days following notice to Axion of clearance by the
Commission  of the Form S-4  called  the  Special  Meeting  for the  purpose  of
approving the Merger and the transactions  contemplated by the Merger Agreement,
the  Distribution  Agreement,  the  Indemnification  Agreement,  the Tax Matters
Agreement,  the Escrow Agreement,  the Transitional Services Agreement,  the AHC
Supply Agreement,  the OnCare Supply Agreement,  the License Agreement,  the AHC
Medstation   Agreement,   the  OnCare  Medstation  Agreement  and  each  of  the
Non-Competition Agreements (collectively,  the "Documents") with such meeting to
be held within twenty business days after the date such meeting is called.

        EMPLOYEE LOANS; EXERCISE OR CANCELATION OF AXION OPTIONS

               Prior  to the Time of  Contribution,  Axion  intends  to make the
Employee Loans to certain holders of Axion Options to facilitate the exercise of
such  Axion  Options  by  such  holders.   Immediately  prior  to  the  Time  of
Contribution,  all Axion Options then  outstanding  shall have been exercised or
shall be canceled.

deemed to be effective upon notification by Axion to the transfer agent that the
Distribution  has been  declared and that the transfer  agent is  authorized  to
proceed with the distribution of AHC Preferred Stock,  which  notification Axion
agrees to deliver promptly following such declaration.

occurring prior to the Time of Distribution.

               Unless BMS otherwise consents in writing,  neither AHC nor any of
the 81% AHC  Subsidiaries  and/or any other 81% AHC Subsidiary  will: (i) (A) in
the case of AHC,  liquidate,  dissolve or wind up its affairs or (B) in the case
of any 81% AHC Subsidiary, liquidate, dissolve or wind up its affairs unless the
assets of such 81% AHC Subsidiary  (or, if such 81% AHC  Subsidiary  will not be
wholly  owned,  a  proportionate  amount of such assets  equal to the direct and
indirect  ownership  interest of AHC in such 81% AHC Subsidiary)  will have been
distributed to or otherwise acquired by AHC and/or any 81% AHC Subsidiary;  (ii)
(A) merge with or into or consolidate with any other person,  or (B) sell, lease
or otherwise transfer all or substantially all the assets of AHC and the 81% AHC
Subsidiaries,  taken as a whole  (including  by means of the sale of the capital
stock of any subsidiary) to any other person (in each case,  whether in one or a
series of transactions),  unless, in each case, such person explicitly agrees to
assume  the  obligations  of  AHC  and  the  81%  AHC  Subsidiaries   under  the
Indemnification  Agreement,  the Tax Matters  Agreement or the Escrow  Agreement
pursuant to an agreement  reasonably  satisfactory  in form and substance to BMS
and its counsel;  (iii) engage in any recapitalization or restructuring pursuant
to which any cash,  securities or other  property will be distributed in respect
of its capital  stock or effect any other  distribution  (by means of  dividend,
redemption  or  otherwise)  in respect of its capital  stock (other than, in the
case of any 81% AHC Subsidiary,  any such  distribution to AHC); (iv) enter into
any transactions with affiliates of AHC or any 81% AHC Subsidiary unless (1) any
such transaction is between or among AHC and the 81% AHC Subsidiaries or (2) the
terms  of  such  transactions  are  fair  and  reasonable  to AHC or the 81% AHC
Subsidiaries,  as the case may be,  as in a  comparable  transaction  made on an
arm's length basis between  unaffiliated  parties;  or (v) agree to or otherwise
suffer any of the foregoing in (i), (ii),  (iii) or (iv) above or otherwise take
any action or fail to take any action designed to restrict,  reduce or otherwise
limit  the  rights of the BMS  Indemnified  Parties  under  the  Indemnification
Agreement,  the Tax Matters  Agreement or the Escrow Agreement or the ability of
any  BMS  Indemnified  Party  to  collect  any  amount  owed  to  it  under  the
Indemnification  Agreement,  the Tax Matters  Agreement or the Escrow Agreement.
For  purposes of this  covenant,  OnCare and its  subsidiaries  are deemed to be
affiliates of AHC and the 81% AHC Subsidiaries.

               AHC will cause each of its subsidiaries that will be or become an
81% AHC  Subsidiary  on or after the  Closing  Date to enter into an  agreement,
reasonably  satisfactory  in form and  substance to both BMS and its counsel and
AHC and its counsel, pursuant to which such subsidiary will agree to be bound by
the terms of each of

the  Indemnification  Agreement,  the  Tax  Matters  Agreement  and  the  Escrow
Agreement as if such subsidiary were named an 81% AHC Subsidiary therein.

               The  foregoing  provisions  of this  "--Covenants"  section  will
terminate on the later of (a) the sixth  anniversary  of the Effective  Time and
(b) the  expiration  of the statute of  limitations  (including  any  extensions
thereof arising from audits  commenced on or before such sixth  anniversary) for
all Federal  income tax returns of the  Affiliated  Group (as defined in the Tax
Matters  Agreement)  for all taxable  years ending on or before the day on which
the Effective Time occurs is in process,  provided that the foregoing provisions
shall not  terminate  until such time as any Tax  Claims (as  defined in the Tax
Matters  Agreement)  relating to such audit or contest have been settled and all
liabilities related thereto satisfied.

        APPOINTMENT OF AHC AS REPRESENTATIVE

               Execution  and  delivery  of the  Letter of  Transmittal  by each
Former  Axion  Stockholder  will  result in each such Former  Axion  Stockholder
irrevocably  appointing  AHC as  his/her  or its agent and  attorney-in-fact  to
execute and  deliver on such  Former  Axion  Stockholder's  behalf,  and thereby
result in each such Former Axion  Stockholder  becoming a party to and bound by,
the Indemnification  Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution  and  delivery  of  the  Letter  of  Transmittal  will  result  in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder   that  may  be  necessary  in  connection  with  the   transactions
contemplated by such  agreements,  including to give and receive notices on each
such Former Axion  Stockholder's  behalf and to represent each such Former Axion
Stockholder  with  respect to any  matter,  suit,  claim,  action or  proceeding
arising  with  respect  to any  transaction  contemplated  by  such  agreements,
including the defense,  appeal or settlement of any claim,  action or proceeding
for which each such Former Axion  Stockholder  may be obligated to indemnify any
person  pursuant  to  such  agreements  or may be  entitled  to  indemnification
pursuant to such  agreements  or which may be brought by BMS  against  each such
Former Axion Stockholder to enforce such indemnity; and will result in each such
Former Axion Stockholder ratifying and confirming any action taken by AHC in the
exercise of the power of attorney granted thereby.

               See "Special  Factors--Indemnification  Obligations of the Former
Axion  Stockholders,  AHC and the 81% AHC  Subsidiaries"  and "Risk Factors" and
"The  Merger--Indemnification   Arrangements;  Escrow;  Appointment  of  AHC  as
Representative"  in the Proxy  Statement/Prospectus  to which  this  Information
Statement is attached as Appendix G.

TERMS OF THE TAX MATTERS AGREEMENT

               Prior to the Time of Distribution,  BMS, BMS Sub, Axion,  certain
subsidiaries of Axion, AHC, the 81% AHC  Subsidiaries,  the Partnership and each
of the Former Axion  Stockholders will enter into a Tax Matters  Agreement,  the
form of which is  attached as  Appendix D to the Proxy  Statement/Prospectus  to
which this  Information  Statement is attached as Appendix G and is incorporated
herein by reference (as it may be amended,  supplemented  or otherwise  modified
from time to time,  the "Tax Matters  Agreement")  which sets forth each party's
rights and  obligations  with  respect to payments of Federal,  state,  local or
foreign Taxes for periods  before and after the Merger and related  matters such
as the filing of and right to tax returns and the control of tax contests.

               The Tax Matters  Agreement  specifically  provides  that: the AHC
Indemnifying Parties will jointly and severally indemnify and hold harmless BMS,
the Surviving  Corporation,  OPUS, OTNC, the  Partnership,  their affiliates and
each of their respective officers, directors,  employees,  stockholders,  agents
and  representatives  (collectively,  the "BMS  Indemnified  Parties")  from all
liabilities for Federal,  state,  local,  foreign and other governmental  taxes,
assessments,  duties,  fees, levies or similar charges of any kind including all
interest,   penalties  and  additions  imposed  with  respect  to  such  amounts
(collectively, "Taxes") imposed on Axion, OPUS, OTNC or any member of Affiliated
Group (as defined in the Tax Matters Agreement)  (whether imposed directly or by
reason of United  States  Treasury  Regulations  Section  1.1502-76  or  similar
provisions) (i) for any pre-merger tax period,  including any Pre-JV Sales Taxes
(but excluding any Retained Tax  Liabilities),  which are in each case unpaid as
of the Effective Time (the "Pre-Merger  Taxes"),  such Indemnified  Taxes,  (ii)
with respect to the Contributions,  (iii) as
    

                                       35

a result  of the  Distribution,  (iv) as a result of the  provision  of the OPUS
Station Data (as defined in the Distribution Agreement) to AHC, OnCare or any of
their  assignees,  (v) with  respect to the OPUS  License  Agreement  or (vi) in
respect  of  the  transfer  of  assets  or  rights  from  OnCare  or  any of its
subsidiaries or affiliates or any other affiliate of Axion and its  subsidiaries
to Axion prior to the  Distribution.  The AHC  Indemnifying  Parties  shall also
jointly and severally indemnify the BMS Indemnified Parties from all liabilities
for fifty  percent  (50%) of any  liability  for any unpaid Taxes (other than JV
Sales Taxes) as of June 30, 1996 imposed on the  Partnership  for all periods up
to and including June 30, 1996 in excess of $225,000,  and 100% of any liability
for JV Sales  Taxes paid after June 30,  1996 in excess of  $667,402;  provided,
however,  that no indemnification  shall be payable with respect to any JV Sales
Taxes to the  extent  payment  of such JV Sales  Taxes  increased  the amount of
"Retained  Cash" pursuant to clause (c) of the definition of "Retained  Cash" in
the Distribution Agreement. "Retained Tax Liabilities" shall mean (W) any income
Tax  liability  (including  any  liability  for any Tax measured by reference to
income) of OTNC (or the Affiliated Group) attributable to the allocation to OTNC
of Taxable income of the Partnership  (whether or not such taxes are paid before
or  after  the  Effective  Time)  and any  other  Taxes to the  extent  directly
attributable  to the operation of the  Partnership,  in each case for the period
beginning  on July 1, 1996,  and ending on the day on which the  Effective  Time
occurs  and in each  case  determined  in  accordance  with  certain  principles
provided therein and (for the avoidance of doubt), in the case of Taxes measured
by  reference to income,  by assuming  that such income is subject to Tax at the
highest  applicable  federal,  state,  and local tax rate as otherwise  provided
therein,  (X) any income Tax  liability  (including  any  liability  for any Tax
measured by  reference  to income) to the extent  directly  attributable  to the
reallocation of Partnership income by the IRS or any other  governmental  agency
from  Bristol-Myers  Oncology  Therapeutics Network Inc., a Delaware corporation
and a wholly owned subsidiary of BMS ("BMOTN") to OTNC, (Y) all liabilities  for
any  unpaid Taxes as of June 30, 1996 imposed on the Partnership for all periods
up  to  and  including  June  30,  1996  that  are  not  indemnified  by the AHC
Indemnifying  Parties  pursuant  to  the  preceding  sentence,  and  (Z) any Tax
liabilities  relating  to  the   operations,   assets   or  activities  of a BMS
Entity  (other  than  the Partnership).  "Pre-JV  Sales  Taxes"  shall  mean any
liability  of Axion with respect to unpaid sales and use Taxes on sales prior to
the  date  of  formation of  the  Partnership.  "JV Sales  Taxes" shall mean any
liability  of  the  Partnership  with  respect  to unpaid sales and use Taxes on
sales prior to August 1, 1994.

               The BMS Indemnifying Parties will jointly and severally indemnify
and hold harmless the AHC  Indemnified  Parties (A) from all liability for Taxes
imposed on the Surviving  Corporation,  OTNC,  OPUS or the  Partnership  for any
Post-Merger Tax Period and (B) for any Retained Tax Liabilities.

               Other  provisions of the Tax Matters  Agreement  provide AHC with
the ability, under certain circumstances,  to control tax contests relating to a
claim for which AHC would  indemnify  the BMS  Indemnified  Parties  and,  under
certain circumstances, allow AHC to obtain refunds for taxes paid by Axion prior
to the Effective Time, up to a certain threshold.

               The indemnification  obligations of the AHC Indemnifying  Parties
under the Tax Matters Agreement  survive for the term of the applicable  statute
of  limitations  (generally  six  years).  Other  than in the case of fraud by a
Former Axion Stockholder,  the  indemnification  obligations of the Former Axion
Stockholders are limited to the Escrowed Shares; the indemnification obligations
of AHC are unlimited.

        APPOINTMENT OF AHC AS REPRESENTATIVE

               Execution  and  delivery  of the  Letter of  Transmittal  by each
Former  Axion  Stockholder  will  result in each such Former  Axion  Stockholder
irrevocably  appointing  AHC as  his/her  or its agent and  attorney-in-fact  to
execute and  deliver on such  Former  Axion  Stockholder's  behalf,  and thereby
result in each such Former Axion  Stockholder  becoming a party to and bound by,
the Indemnification  Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution  and  delivery  of  the  Letter  of  Transmittal  will  result  in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder   that  may  be  necessary  in  connection  with  the   transactions
contemplated by such  agreements,  including to give and receive notices on each
such Former Axion  Stockholder's  behalf and to represent each such Former Axion
Stockholder  with  respect to any  matter,  suit,  claim,  action or  proceeding
arising  with  respect  to any  transaction  contemplated  by  such  agreements,
including the defense,  appeal or settlement of any claim,  action or proceeding
for which each such Former Axion  Stockholder  may be obligated to
    

                                       36

indemnify  any  person   pursuant  to  such  agreements  or may be  entitled  to
indemnification  pursuant  to such  agreements  or which may be  brought  by BMS
against each such Former Axion  Stockholder to enforce such indemnity;  and will
result in each such Former Axion Stockholder ratifying and confirming any action
taken by AHC in the exercise of the power of attorney granted thereby.

               See "Special  Factors--Indemnification  Obligations of the Former
Axion  Stockholders,  AHC and the 81% AHC  Subsidiaries"  and "Risk Factors" and
"The  Merger--Indemnification   Arrangements;  Escrow;  Appointment  of  AHC  as
Representative"  in the Proxy  Statement/Prospectus  to which  this  Information
Statement is attached as Appendix G.

TERMS OF THE ESCROW AGREEMENT

        DEPOSIT OF ESCROWED PROPERTY

               Pursuant to the Escrow Agreement, at the Closing (a) the Exchange
Agent, on behalf of the Former Axion Stockholders, will deposit into escrow, and
the Escrow Agent will  acknowledge  receipt of, a number of shares of BMS Common
Stock  equal to $5 million  divided by the  Average  Value of BMS Common  Stock,
rounded to the nearest  whole  share,  which  amount will be deemed to have been
deposited by the Former Axion  Stockholders  on a pro rata basis from the shares
of BMS Common Stock to be issued and delivered to each Former Axion  Stockholder
with  respect  to its  shares  of Axion  Common  Stock  pursuant  to the  Merger
Agreement as described under "The Merger" in the Proxy  Statement/Prospectus  to
which this Information  Statement is attached as Appendix G, calculated based on
the  ratio of the  number  of shares  of BMS  Common  Stock to be so issued  and
delivered to such Former Axion  Stockholder  with respect to its shares of Axion
Common  Stock to the  aggregate  number of shares of BMS  Common  Stock to be so
issued to all the Former  Axion  Stockholders  with  respect to their  shares of
Axion Common Stock.  Such shares  together with any dividends and  distributions
with respect to such shares as set forth in the Escrow Agreement are referred to
as the "Escrowed  Shares",  and (b) AHC will  deposit,  or cause to be deposited
into  escrow,  and the Escrow Agent will  acknowledge  receipt of, $5 million in
cash.  Such cash,  together with any income received  thereon,  as on deposit or
invested from time to time in accordance with the terms of the Escrow Agreement,
is referred to as the "Escrowed Cash" (the Escrowed Shares and the Escrowed Cash
together  being  the  "Escrowed  Property").  During  the  term  of  the  Escrow
Agreement,  BMS  will,  from  time to time and  concurrently  with  the  payment
thereof,  (a)  deliver to the Escrow  Agent for deposit in  accordance  with the
terms of the  Indemnification  Agreement,  all  non-taxable  stock dividends and
other non-taxable distributions made with respect to the Escrowed Shares and (b)
deliver to the Escrow Agent, who will promptly distribute the same to the Former
Axion  Stockholders,  all cash  distributions  and other  taxable  distributions
(other  than  taxable  distributions  representing  the  proceeds  of a sale  or
acquisition  or a  substantial  restructuring  in  connection  with  a  sale  or
acquisition of only BMS) made with respect to the Escrowed Shares.  BMS and each
AHC Indemnifying  Party acknowledge and agree that, to the extent and so long as
any of the  Escrowed  Property is held by the Escrow Agent  hereunder,  BMS will
have, as of and from the date such  Escrowed  Property is received by the Escrow
Agent, a perfected first priority security interest in such Escrowed Property to
secure the payment of the amount,  if any, payable by an AHC Indemnifying  Party
pursuant to the Indemnification Agreement and the Tax Matters Agreement. Each of
BMS and each of the AHC Indemnifying Parties agree that the Escrowed Shares will
be voted by the Escrow Agent with respect to all matters as to which the holders
of BMS Common Stock are entitled to vote in accordance with written instructions
from AHC as the representative of the Former Axion Stockholders. AHC agrees that
if any Former Axion Stockholder  provides AHC with written  directions as to how
to vote the Escrowed  Shares with respect to any matter,  AHC will  instruct the
Escrow Agent to vote such number of Escrowed Shares as are beneficially held for
such Former Axion  Stockholder as so directed by such Former Axion  Stockholder,
and if no such  directions  are  received  with respect to  particular  Escrowed
Shares on any  matter  for which such  Escrowed  Shares  may be voted,  AHC will
direct the Escrow Agent to abstain from voting such Escrowed Shares with respect
to such matter.

        DISPOSITION OF ESCROWED PROPERTY

               At any time on or prior to the Escrowed Cash Termination Date (as
defined  below),  BMS may deliver a certificate  to the Escrow Agent  requesting
delivery of Escrowed Property to BMS, and the Escrow Agent
    

                                       37

will deliver the Escrowed Property to BMS to the extent and at the time provided
in  accordance  with  the  Escrow  Agreement;  provided,  however,  that  (i) no
distribution  of Escrowed  Property  will be made in respect of any  Indemnified
Obligation  (as defined  below) related to a liability for Taxes for which a BMS
Indemnified  Party is  indemnified  pursuant  to  Section  1 of the Tax  Matters
Agreement  unless and until such time as such liability for Taxes will be deemed
liquidated and therefore  payable in accordance with the provisions of Section 9
of the Tax Matters  Agreement,  (ii) after the Escrowed Shares  Termination Date
(as defined  herein),  no Escrowed  Shares  shall be released to BMS except with
respect to an Escrowed  Shares Pending Claim (as defined herein) and (iii) after
the Second  Anniversary Date (as defined herein),  Second Anniversary Cash shall
be released to BMS only with respect to Second  Anniversary  Pending  Claims (as
defined herein). For purposes of the foregoing, the amount of Second Anniversary
Cash as of any date will equal the  excess,  if any,  of the amount of  Escrowed
Cash on deposit with the Escrow Agent on such date over the amount  specified in
clause (A) of the  definition of "Retained  Escrow  Amount" (as defined  herein)
calculated as of such date.

               Immediately  following the Escrowed Shares  Termination  Date, if
either (a) both BMS and AHC deliver a certificate to the Escrow Agent or (b) the
Escrow Agent (i) receives a  certificate  from AHC, (ii) delivers a copy of such
certificate  to BMS and  (iii)  does  not,  within 15  business  days  following
delivery of such  certificate to BMS,  receive written notice from BMS objecting
to such  certificate  given by AHC,  the Escrow Agent will deliver to AHC as the
representative  of the Former Axion  Stockholders such number of Escrowed Shares
(rounded to the nearest whole share) that equals, when multiplied by the Average
Value of BMS Common  Stock,  the  excess,  if any, of (x) the number of Escrowed
Shares on deposit with the Escrow Agent on the Escrowed Shares  Termination Date
multiplied  by the Average  Value of BMS Common Stock over (y) the amount of any
unpaid  Escrowed Shares Pending Claims (as defined below) on the Escrowed Shares
Termination  Date.  Thereafter,  if as of the  last  day of any  fiscal  quarter
following  the Escrowed  Shares  Termination  Date,  Escrowed  Shares  remain on
deposit  with the  Escrow  Agent,  and  either  (a) both BMS and AHC  deliver  a
certificate  to the  Escrow  Agent  or (b)  the  Escrow  Agent  (i)  receives  a
certificate  from AHC, (ii) delivers a copy of such certificate to BMS and (iii)
does not, within 15 business days following delivery of such certificate to BMS,
receive written notice from BMS objecting to such certificate  given by AHC, the
Escrow  Agent will  deliver  to AHC as the  representative  of the Former  Axion
Stockholders  the number of Escrowed Shares that equals,  when multiplied by the
Average  Value of BMS Common  Stock,  the  excess,  if any, of (x) the number of
Escrowed  Shares on deposit with the Escrow Agent on the last day of such fiscal
quarter  multiplied by the Average Value of BMS Common Stock over (y) the amount
of any unpaid  Escrowed  Shares  Pending  Claims on the last day of such  fiscal
quarter.  "Escrowed  Shares Pending Claims" means all Pending Claims (as defined
below)  existing on the  Escrowed  Shares  Termination  Date.  The amount of any
Escrowed  Shares Pending Claim on any date will be determined in accordance with
the provisions of the Escrow Agreement. "Escrowed Shares Termination Date" means
the earlier to occur of (i) one year after the date of the Escrow  Agreement and
(ii) complete  distribution of the Escrowed Shares in satisfaction of claims for
Indemnified Obligations.

               Immediately  following the second  anniversary of the date of the
Escrow Agreement (the "Second Anniversary Date"), if either (a) both BMS and AHC
jointly  deliver a  certificate  to the Escrow Agent or (b) the Escrow Agent (i)
receives a certificate from AHC, (ii) delivers a copy of such certificate to BMS
and  (iii)  does  not,  within  15  business  days  following  delivery  of such
certificate to BMS, receive written notice from BMS objecting to the certificate
given by AHC,  the Escrow  Agent will  deliver to AHC an amount in cash equal to
the excess,  if any, of Escrowed Cash on deposit with the Escrow Agent as of the
Second   Anniversary  Date  over  the  Retained  Escrow  Amount  on  the  Second
Anniversary  Date.  Thereafter,  if as of the  last  day of any  fiscal  quarter
following the Second Anniversary Date, Escrowed Cash remains on deposit with the
Escrow Agent and either (a) both BMS and AHC deliver a certificate to the Escrow
Agent or (b) the Escrow Agent (i) receives a certificate from AHC, (ii) delivers
a copy of such  certificate  to BMS and (iii) does not,  within 15 business days
following  delivery of such  certificate to BMS, receive written notice from BMS
objecting to such certificate given by AHC, the Escrow Agent will deliver to AHC
an amount in cash equal to the excess,  if any, of Escrowed Cash on deposit with
the Escrow  Agent as of the last day of such fiscal  quarter  over the  Retained
Escrow  Amount  as of the  last day of such  fiscal  quarter.  "Retained  Escrow
Amount" means,  as of any date,  the sum of (A) an amount,  if any, equal to the
excess of $1 million over (i) the  aggregate  amount,  if any, of Escrowed  Cash
that will have been released during the period from the Second  Anniversary Date
to such date in respect of any Pending  Claim that was not an  existing  Pending
Claim  at any  time on or  prior  to the  Second  Anniversary  Date and (ii) the
aggregate amount, if any, released to AHC pursuant to the
    

                                       38

paragraph below from and after the Escrowed Cash  Termination  Date and (B) plus
the amount of any unpaid Second Anniversary Pending Claims on such date. "Second
Anniversary  Pending Claims" means all the Pending Claims existing on the Second
Anniversary Date (and, for the avoidance of doubt,  includes all Escrowed Shares
Pending  Claims  existing  on such date).  The amount of any Second  Anniversary
Pending  Claim  on any  date  will  be  determined  as  provided  in the  Escrow
Agreement,  provided  that,  for all purposes of this  paragraph,  the amount of
unpaid Second  Anniversary  Pending Claims on the last day of any fiscal quarter
ending after the Second  Anniversary  Date will be reduced by an amount equal to
(x) the number of Escrowed  Shares on deposit  with the Escrow Agent on the last
day of such fiscal quarter (such number to be determined based on the assumption
that any Escrowed  Shares that are to be delivered to AHC as the  representative
of the Former AHC Stockholders in respect of the last day of such fiscal quarter
as provided  in the second  sentence  of the  paragraph  above will have been so
delivered  and will not be on deposit  with the Escrow  Agent on the last day of
such fiscal quarter),  if any, multiplied by (y) the Average Value of BMS Common
Stock.

               Immediately  following  the Escrowed  Cash  Termination  Date, if
either (a) both BMS and AHC deliver a certificate to the Escrow Agent or (b) the
Escrow Agent (i) receives a  certificate  from AHC, (ii) delivers a copy of such
certificate  to BMS and  (iii)  does  not,  within 15  business  days  following
delivery of such  certificate to BMS,  receive written notice from BMS objecting
to such certificate given by AHC, the Escrow Agent will deliver to AHC an amount
equal to the excess,  if any, of Escrowed  Cash on deposit with the Escrow Agent
as of the Escrowed Cash  Termination Date (calculated as provided below) over an
amount  equal to any  unpaid  Final  Pending  Claims (as  defined  below) on the
Escrowed Cash Termination Date. Thereafter,  if as of the last day of any fiscal
quarter  following the Escrowed Cash  Termination  Date Escrowed Cash remains on
deposit  with the  Escrow  Agent  and  either  (a) both  BMS and AHC  deliver  a
certificate  to the  Escrow  Agent  or (b)  the  Escrow  Agent  (i)  receives  a
certificate  from AHC, (ii) delivers a copy of such certificate to BMS and (iii)
does not, within 15 business days following delivery of such certificate to BMS,
receive written notice from BMS objecting to such certificate  given by AHC, the
Escrow  Agent will  deliver to AHC an amount  equal to the  excess,  if any,  of
Escrowed Cash on deposit with the Escrow Agent as of the last day of such fiscal
quarter  (calculated as provided below) over an amount equal to any unpaid Final
Pending  Claims on the last day of such  fiscal  quarter.  For  purposes of this
paragraph, the amount of any Escrowed Cash on deposit with the Escrow Agent will
be  calculated  by treating the amount,  if any, of Escrowed  Cash that is to be
delivered to AHC pursuant to the paragraph  above on such date as having been so
delivered and as not being on deposit with the Escrow Agent on such date. "Final
Pending  Claims"  means  all  Pending  Claims  existing  on  the  Escrowed  Cash
Termination Date (and, for the avoidance of doubt,  includes all Escrowed Shares
Pending Claims and Second Anniversary Pending Claims existing on such date). The
amount of any Final  Pending Claim on any date will be determined as provided in
the Escrow  Agreement,  provided that, for purposes of this paragraph the amount
of unpaid  Final  Pending  Claims on the last day of any fiscal  quarter  ending
after the Escrowed Cash  Termination  Date will be reduced by an amount equal to
(x) the number of Escrowed  Shares on deposit  with the Escrow Agent on the last
day of such fiscal quarter (such number to be determined based on the assumption
that any Escrowed  Shares that are to be delivered to AHC as the  representative
of the Former AHC Stockholders in respect of the last day of such fiscal quarter
is provided in the second sentence of the second paragraph of  "--Disposition of
Escrowed  Property" above will have been so delivered and will not be on deposit
with  the  Escrow  Agent  on the  last  day of  such  fiscal  quarter),  if any,
multiplied  by (y) the Average Value of BMS Common  Stock.  The  "Escrowed  Cash
Termination  Date" means the earlier to occur of (i) six years after the date of
the Escrow  Agreement  and (ii)  complete  distribution  of the escrowed cash in
satisfaction of claims for Indemnified Obligations.

               Either BMS or AHC may deliver to the Escrow  Agent a  certificate
accompanied by a final and nonappealable  award or order of a court of competent
jurisdiction (a "Court Order") with respect to the payment of all or any portion
of the Escrowed Property requesting delivery of Escrowed Property to BMS, AHC or
such  other  person(s)  as may  be  specified  in  such  award  or  order.  Such
certificate  also will be  accompanied  by an opinion of outside  counsel to the
effect that the applicable court award or order is final and  nonappealable.  In
either such case, the Escrow Agent will deliver all or a portion of the Escrowed
Property to BMS or AHC, as the case may be, in the amount specified in the Court
Order.

               If AHC has  delivered  to the  Escrow  Agent  and BMS at any time
within 30 days before or after the due date  (including  extensions) for payment
by AHC of its final  Federal  income tax  liability  for a taxable  year (or, if

later, 30 days after the Escrow Agent supplies all  information  relating to the
income  realized  with  respect to the  Escrowed  Cash  necessary to prepare the
certificate referred to in this paragraph a certificate setting forth the amount
of Federal and State of  California  income tax due from AHC with respect to any
taxable income  realized with respect to the Escrowed Cash for such taxable year
(based on the  assumption  that AHC is, with respect to such income,  subject to
Federal and State of California  income tax at the highest regular  marginal tax
rate  applicable  to  corporations   for  such  year),   and  the  accuracy  and
completeness  of such  certificate  is  certified by Ernst & Young or such other
nationally recognized accounting firm chosen by AHC and reasonably  satisfactory
to BMS,  then the  Escrow  Agent will pay to AHC in cash the amount set forth in
such  certificate  no more than fifteen days after receipt of such  certificate.
The Escrow Agent will use commercially  reasonable  efforts to supply to AHC the
tax  information  referred  to above  prior to the  start of the  60-day  period
referred to above.

               All  distributions  under the Escrow  Agreement  that are not the
subject  of a  dispute  will be made no later  than 20 days  from  receipt  of a
certificate  and will be made from the Escrowed Shares and/or the Escrowed Cash,
as the  case  may  be,  in  accordance  with  the  provisions  described  above.
Distributions made to BMS pursuant to the provisions  described above will first
be made from any Escrowed Shares on deposit and then, to the extent so required,
from any Escrowed Cash.  Distributions made pursuant to the preceding  paragraph
will be deemed to have been made from the Escrowed Cash.

               If BMS delivers a written notice to the Escrow Agent objecting to
any Certificate from AHC requesting the release of the Escrowed  Property,  such
notice must specify the disputed  amount of such release  request and the amount
not in dispute.  The Escrow Agent will deliver to AHC the amount of such release
request not in dispute.

               Each Escrowed Share distributed  pursuant to the Escrow Agreement
is valued at a price per share equal to the Average  Value of BMS Common  Stock,
rounded to the nearest whole share. All Escrowed Shares  distributed to AHC will
be  distributed  by AHC pro rata to the Former Axion  Stockholders  based on the
ratio of the number of shares of BMS Common Stock  received by such Former Axion
Stockholder at the Closing to the aggregate number of shares of BMS Common Stock
received by all Former Axion Stockholders at the Closing.

        DISTRIBUTIONS FOR INDEMNIFIED OBLIGATIONS

               At any time on or prior to the Escrowed  Cash  Termination  Date,
BMS may deliver to the Escrow  Agent a  certificate  (i) stating  that (A) a BMS
Indemnified  Party has incurred an  Indemnifiable  Loss  against  which such BMS
Indemnified Party is entitled to be indemnified  pursuant to the Indemnification
Agreement or (B) a BMS Indemnified  Party is liable for Taxes against which such
BMS Indemnified Party is entitled to be indemnified  pursuant to the Tax Matters
Agreement (each, an "Indemnified Obligation"), (ii) stating the aggregate amount
of such Indemnified  Obligation (or, in the case of an unliquidated  Indemnified
Obligation,  a good faith and reasonable  estimate thereof) and (iii) specifying
in  reasonable  detail  the  nature of each item  included  in such  Indemnified
Obligation (an "Indemnification Item"), the amount thereof and the date on which
such Indemnification Item was paid or incurred;  provided, however, that BMS may
not deliver to the Escrow Agent a  certificate  stating  that a BMS  Indemnified
Party is liable for Taxes against which such BMS  Indemnified  Party is entitled
to be indemnified  pursuant to the Tax Matters Agreement unless and until any of
the  following  will have  occurred:  (a) a Tax  Return  will have been filed as
provided in the Tax Matters  Agreement  showing such Taxes to be due and payable
and the full  amount of such  Taxes will not have been paid at the time such Tax
Return  was  filed;  (b) a Taxing  Authority  will have  asserted  in writing or
determined  that there is a deficiency  with  respect to such Taxes;  (c) except
with respect to any claim for  indemnification for Taxes relating in any respect
to (i) the  Contributions,  the  Distribution,  the  Merger  or any of the other
Transactions,  (ii) any sales or use Taxes,  other than (A) Pre-JV  Sales Taxes,
(B) JV Sales  Taxes and (C) any  liability  of any BMS  Indemnified  Party  with
respect to unpaid sales and use taxes on rentals of OPUS Station  machines,  and
(iii) the  distribution of the stock of OnCare by Axion,  BMS will have received
an opinion of a nationally  recognized  accounting  firm or law firm  reasonably
acceptable  to AHC  that it is more  likely  than not that  such  Taxes  will be
properly payable;  or (d) there will have been a "determination"  (as defined in
Section 1313 of the Code) that such Taxes are due and payable.

               If AHC objects to the  Indemnified  Obligation  specified in such
certificate,  AHC will,  within 10 business  days after  delivery of the written
notice containing a copy of any such Certificate,  deliver to the Escrow Agent a
certificate (a "Reply  Certificate"),  (i) specifying  each such amount to which
AHC objects and (ii)  specifying in  reasonable  detail the nature and basis for
each such  objection.  Within five business days of delivery to the Escrow Agent
of a Reply  Certificate,  the  Escrow  Agent  will  deliver a copy of such Reply
Certificate  to BMS. BMS and AHC will negotiate in good faith for a period of 30
days  after  delivery  of such  Reply  Certificate  to BMS to  reach  a  written
resolution of any matters raised in a Reply Certificate.
   
               If  no  Reply  Certificate  is  delivered  with  respect  to  any
certificate  or any  Indemnification  Item contained  therein,  then AHC will be
deemed to have  acknowledged  BMS's  right to  receive  any  amount  or  amounts
specified in such  certificate  (or the  undisputed  portion  thereof),  and the
Escrow Agent will transfer to BMS,  Escrowed  Property in an amount equal to the
undisputed amount claimed in such certificate (plus interest at a rate per annum
equal to the prime rate announced from time to time by The Chase  Manhattan Bank
on such amount from the later of (i) the date of such  certificate  and (ii) the
date such indemnified amount was actually incurred by the applicable Indemnified
Party), all in accordance with the procedures set forth in the Escrow Agreement.
    
               If the  Escrow  Agent  receives a Reply  Certificate  in a timely
manner,  the  disputed  amount  requested  for  reimbursement  pursuant  to  the
applicable certificate will be held by the Escrow Agent and will not be released
to BMS except in accordance with either (i) written  instructions signed by each
of an authorized officer of BMS and AHC or (ii) the final nonappealable judgment
of a court  having  jurisdiction  over the matters  relating to the claim by the
applicable  Indemnified  Party for  indemnification  from AHC  accompanied by an
opinion of outside  counsel to the effect that the applicable  judgment is final
and  nonappealable,  at  which  date  the  portion  of the  amount  due to  such
Indemnified  Party determined  pursuant to clauses (i) or (ii) in this paragraph
will promptly be paid to BMS in accordance  with the procedures set forth in the
Escrow Agreement.
   
               The payment of Indemnified Obligations contemplated by the Escrow
Agreement  will not be deemed to be a waiver  of any  right,  claim or amount to
which BMS may be entitled under the Indemnification  Agreement,  the Tax Matters
Agreement  or  otherwise,   including  any  claim  relating  to  an  Indemnified
Obligation,  to the  extent  that the  amount  paid to BMS  pursuant  hereto  is
insufficient to satisfy the entire amount of any such Indemnified Obligation.
    
               Notwithstanding   anything   to  the   contrary   set   forth  in
"--Disposition  of  Escrowed  Property"  and  "--Distributions  for  Indemnified
Obligations",  upon receipt of written notice from the Escrow Agent containing a
copy of a certificate relating to an Indemnified  Obligation the final amount of
which will have been liquidated, AHC may elect to pay to BMS such amount in cash
in lieu of payment  being made from the  Escrowed  Property  if AHC,  within ten
business  days after  delivery of the written  notice  containing  a copy of the
certificate,  will have  delivered to BMS and the Escrow Agent a written  notice
stating its election to make such cash payment and,  thereafter,  will have made
such  cash  payment  to BMS on the  earliest  date that a  payment  of  Escrowed
Property  would  otherwise be made  hereunder  with respect to such  Indemnified
Obligation;  provided, however, that such Indemnified Obligation will constitute
a  Pending  Claim for all  purposes  of this  Agreement  until the time the full
amount of such cash payment is actually received by BMS.

        PENDING CLAIMS

               "Pending  Claims"  means,  at any time,  (a) all  indemnification
claims with respect to which a certificate  will have been delivered at or prior
to such time with  respect to which the final  amount of such  claims  will have
been  liquidated  and which will not have been paid in full at such time whether
because  the  payment  of such  amount is in dispute  or  otherwise  and (b) all
indemnification  claims  with  respect  to which a  Certificate  will  have been
delivered and with respect to which the final amount of such claim will not have
been liquidated.
   
               The amount of any  Pending  Claim as of any date will be equal to
BMS's  reasonable  estimate of such amount.  If any Pending  Claim exists on the
last day of any fiscal  quarter  during the term of the  Escrow  Agreement,  not
later than 10 business days after the last day of such fiscal quarter,  BMS will
deliver to the Escrow Agent a certificate  (a "Quarterly  Certificate")  setting
forth BMS's reasonable estimate of the amount of each then
    

                                       41

<PAGE>

existing Pending Claim as of the last day of such fiscal quarter, provided that,
if BMS will not deliver a Quarterly Certificate in respect of any fiscal quarter
or will not include in such Quarterly Certificate all Pending Claims existing on
the last day of such fiscal  quarter,  the amount of each Pending  Claim (or the
amount of any Pending  Claim not  included  in such  Quarterly  Certificate,  as
applicable)  will be the amount of each such Pending Claim set forth in the most
recent Certificate (including any Quarterly Certificate) delivered by BMS to the
Escrow Agent in respect of the amount of such Pending  Claim,  provided  further
that failure of BMS to deliver a Quarterly  Certificate in respect of any fiscal
quarter will not affect in any manner the  obligations  of the AHC  Indemnifying
Parties under the Escrow  Agreement,  the  Indemnification  Agreement or the Tax
Matters  Agreement  or the  rights  of BMS or any other  BMS  Indemnified  Party
thereunder.

               If AHC  reasonably  objects  to the amount of any  Pending  Claim
specified in any certificate  delivered  pursuant to the Escrow  Agreement,  AHC
will, within 10 business days after delivery of such certificate, deliver to the
Escrow Agent a certificate (the "Amount Certificate"),  (i) specifying each such
amount to which AHC reasonably  objects and (ii) specifying in reasonable detail
the nature  and basis for each such  objection.  Within  five  business  days of
delivery to the Escrow  Agent of the Amount  Certificate,  the Escrow Agent will
deliver a copy of such Amount  Certificate to BMS. BMS and AHC will negotiate in
good faith for a period of 30 days after  delivery by the Escrow Agent to BMS of
such Amount  Certificate to reach a written  resolution of any matters raised in
the Amount  Certificate  and, if such matters are not  resolved  within a 30-day
period,  either party may bring an action to resolve such dispute as provided in
the Escrow Agreement.  Notwithstanding the foregoing,  the amount of any Pending
Claim with respect to which an Amount  Certificate will have been delivered will
be for all purposes of the Escrow Agreement the amount reasonably  determined by
BMS as provided in the paragraph  above unless and until such time as the Escrow
Agent either (a) receives written  instructions  signed by an authorized officer
of each of BMS and AHC  adjusting  the amount of such  Pending  Claim or (b) the
final  nonappealable  judgment of a court having  jurisdiction  over the matters
relating   to  the  claim  by  the   applicable   BMS   Indemnified   Party  for
indemnification  from any AHC  Indemnifying  Party  adjusting the amount of such
Pending Claim  accompanied  by an opinion of outside  counsel to the effect that
the applicable judgment is final and nonappealable,  at which date, in the event
that the Escrow Agent will have received an Amount  Certificate  from AHC within
the time frame set forth above, the amount of the Pending Claim for all purposes
of this Agreement will be adjusted to the amount determined  pursuant to clauses
(a) or (b) of this sentence.
   
        ESCROW AGENT

               The  Escrow  Agent  shall  not be  liable  except  for its  gross
negligence or wilful misconduct,  and shall be indemnified jointly and severally
by the AHC Indemnifying  Parties and the BMS Indemnifying Parties against losses
or claims arising out of or in connection with the Escrow Agreement.  The Escrow
Agent will be required to make all Escrowed Property available for withdrawal on
not less than two business days' prior written notice.

        APPOINTMENT OF AHC AS REPRESENTATIVE

               Execution  and  delivery  of the  Letter of  Transmittal  by each
Former  Axion  Stockholder  will  result in each such Former  Axion  Stockholder
irrevocably  appointing  AHC as  his/her  or its agent and  attorney-in-fact  to
execute and  deliver on such  Former  Axion  Stockholder's  behalf,  and thereby
result in each such Former Axion  Stockholder  becoming a party to and bound by,
the Indemnification  Agreement, Tax Matters Agreement and Escrow Agreement. Such
execution  and  delivery  of  the  Letter  of  Transmittal  will  result  in the
irrevocable appointment of AHC as each such Former Axion Stockholder's agent and
attorney-in-fact to take any and all actions on behalf of each such Former Axion
Stockholder   that  may  be  necessary  in  connection  with  the   transactions
contemplated by such  agreements,  including to give and receive notices on each
such Former Axion  Stockholder's  behalf and to represent each such Former Axion
Stockholder  with  respect to any  matter,  suit,  claim,  action or  proceeding
arising  with  respect  to any  transaction  contemplated  by  such  agreements,
including the defense,  appeal or settlement of any claim,  action or proceeding
for which each such Former Axion  Stockholder  may be obligated to indemnify any
person  pursuant  to  such  agreements  or may be  entitled  to  indemnification
pursuant to such  agreements  or which may be brought by BMS  against  each such
Former Axion Stockholder to enforce such

indemnity;  and will result in each such Former Axion Stockholder  ratifying and
confirming  any action  taken by AHC in the  exercise  of the power of  attorney
granted thereby.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

               The following  summary  describes the material federal income tax
consequences  of the  Distribution  to  holders of Axion  capital  stock who are
citizens or residents of the United States.  This  discussion  does not consider
all the tax consequences that may be relevant to Axion stockholders  entitled to
special  treatment  under the Code  (such as  insurance  companies,  dealers  in
securities,  tax exempt organizations or, except as specifically provided below,
foreign  persons) or to Axion  stockholders  who acquired  their shares of Axion
Common Stock  pursuant to the exercise of employee stock options or otherwise in
compensatory  transactions.  In addition,  this  discussion does not address any
state,  local or foreign  tax  considerations  nor does it address  any  federal
estate,  gift,  employment,  excise or other non-income tax  consideration.  The
following  discussion  is  based  upon  provisions  of  the  Code,  regulations,
administrative  rulings and judicial decisions presently in effect, all of which
are  subject  to change  (possibly  with  retroactive  effect)  or to  different
interpretations.  ALL  AXION  STOCKHOLDERS  ARE URGED TO  CONSULT  THEIR OWN TAX
ADVISORS  AS TO THE  SPECIFIC  TAX  CONSEQUENCES  TO THEM  OF THE  DISTRIBUTION,
INCLUDING THE APPLICABILITY OF FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS.

               In the opinion of Ernst & Young,  certified public accountants to
Axion,  based upon  certain  representations  of BMS,  BMS Sub,  Axion,  AHC and
certain Former Axion Stockholders, the Distribution should qualify as a tax-free
spinoff under Section 355 of the Code. In such event, the following consequences
would obtain:
    
               1. An Axion stockholder should not recognize any income,  gain or
loss as a result of the Distribution.

               2. An Axion stockholder  should apportion the tax basis of his or
her Axion Common Stock between such Axion Common Stock and AHC  Preferred  Stock
received in the distribution in proportion to the relative fair market values of
such Axion  Common  Stock and AHC  Preferred  Stock  immediately  following  the
Distribution.
   
               3. An Axion  stockholder's  holding  period for the AHC Preferred
Stock received in the Distribution  should include the holding period applicable
to the Axion  Common  Stock  with  respect to which the  Distribution  was made,
provided  that  such  Axion  Common  Stock  is held as a  capital  asset by such
stockholder as of the date of the Distribution.

               4. Under  current  law, no gain or loss should be  recognized  by
Axion as a result of the  Distribution,  except to the extent  that  immediately
after  the  Distribution  AHC  Preferred  Stock is owned  (either  directly,  or
indirectly  through one or more  entities that are treated for United States tax
purposes  as  partnerships,  estates or trusts) or deemed to be owned by certain
individuals who are not citizens or residents of the United States or by certain
foreign corporations (such actual or deemed owners are collectively  referred to
herein as "Non-United  States  Holders").  AHC Preferred  Stock that is owned by
entities  that are  treated  for United  States tax  purposes  as  partnerships,
estates  or trusts  will for this  purpose be deemed to be  indirectly  owned by
Non-United States Holders unless certain  certification  procedures are complied
with by the partners of such partnerships or the beneficiaries of such trusts or
estates.  In the case of such direct or indirect ownership by certain Non-United
States  Holders,  Axion will  recognize gain in an amount equal to the excess of
the value of the AHC Preferred Stock that is so held by such  Non-United  States
Holders over Axion's tax basis in such stock. It is expected that at the Time of

    



                                       43


 
<PAGE>
 

<PAGE>
   
Distribution  a  substantial  portion  of  Axion  Common  Stock  will be held by
Non-United States Holders. Based on Axion's business judgment as to the value of
the businesses to be distributed  by Axion in the  Distribution,  Axion does not
expect  to  report  a  material  amount  of tax  liability  as a  result  of the
distribution of AHC Preferred Stock to Non-United States Holders. It should also
be noted that  legislation (the "Proposed  Legislation")  has been proposed that
would cause the  Distribution  to  constitute a taxable  event to Axion  whereby
Axion would  recognize gain in an amount equal to the excess of the value of the
AHC Preferred Stock distributed over Axion's tax basis in such stock, whether or
not such  stock is  owned by  Non-United  States  Holders.  While  the  Proposed
Legislation  has not yet been  enacted  into  law,  as  currently  drafted  such
legislation would, if enacted, apply retroactively to the Distribution. Based on
Axion's business judgment as to the value of the businesses to be distributed by
Axion in the Distribution,  Axion does not expect to report a material amount of
tax liability on its federal income tax returns as a result of the  distribution
of AHC  Preferred  Stock even if the Proposed  Legislation  were adopted with an
effective  date that  applied to the  Distribution.  There can be no  assurance,
however,  that the IRS will  agree  with  Axion's  business  judgment  as to the
valuation of the businesses to be distributed  by Axion in the  Distribution  or
will not  establish a higher  valuation  that would make  Axion's tax  liability
higher, and, accordingly, there can be no assurance that the distribution of the
AHC Preferred Stock to Non-United States Holders or the adoption of the Proposed
Legislation  would not cause Axion to incur a material  amount of tax liability.
Pursuant to the Tax Matters Agreement,  the AHC Indemnifying Parties have agreed
to indemnify the BMS Indemnified  Parties against such tax liability,  which may
result  in a claim  against  part or all of the  Escrowed  Cash or the  Escrowed
Shares or  directly  against the AHC  Indemnifying  Parties.  Regardless  of the
existence of Non-United  States  Holders or whether the Proposed  Legislation is
adopted, Axion and/or its subsidiaries may also be required to recognize gain as
a result of the  transfer  of  various  assets  and  liabilities  among  various
entities in anticipation of the Distribution.

               No ruling from the IRS has been or will be sought with respect to
any of the tax  matters  relating  to the  Distribution.  The opinion of Ernst &
Young  described  above  will not be  binding  on the IRS.  In  addition,  Axion
stockholders  should  be aware  that  such  opinion  is based on Ernst & Young's
interpretation  as to how various  requirements of Code Section 355 should apply
to the particular facts presented by the  Distribution.  With respect to some of
these interpretations,  no direct legal precedents exist. Accordingly, there can
be no assurance  that the IRS will agree with the  conclusions  set forth in the
Ernst & Young opinion.  Moreover, no published rulings or cases squarely address
the qualifications of a transaction  identical to the Distribution under Section
355 of the Code.
    
               A  successful   IRS  challenge  to  the   qualification   of  the
Distribution as a tax-free spinoff  qualifying under Section 355 of the Code (as
a result of the inaccuracy of any of the representations of BMS, BMS Sub, Axion,
AHC or certain  Former Axion  Stockholders,  or  otherwise)  would result in the
following consequences:
   
               1. Axion would recognize gain in an amount equal to the excess of
the value of the AHC Preferred  Stock  distributed  to Axion  stockholders  over
Axion's tax basis in such stock (to the extent such gain has not previously been
recognized by Axion in connection  with the  distribution of AHC Preferred Stock
to Non-United  States  Holders).  As noted above,  Axion does not expect that it
would  incur a material  amount of tax  liability.  Also as noted  above,  Axion
and/or its  subsidiaries  may also be required to recognize  gain as a result of
the  transfer  of various  assets and  liabilities  among  various  entities  in
anticipation  of  the  Distribution,  regardless  of  whether  the  Distribution
qualifies as a tax-free spinoff under Section 355 of the Code.

               2. The receipt of AHC Preferred Stock would  constitute a taxable
distribution to all Axion stockholders  (including Non-United States Holders) so
that the fair  market  value of the AHC  Preferred  Stock  received  by an Axion
stockholder  would be  treated  (i) first,  as a dividend  to the extent of such
Axion  stockholder's  share of Axion's  current  and  accumulated  earnings  and
profits,  (ii)  next,  as a  tax-free  return of  capital  to the extent of such
stockholder's  tax basis in the Axion Common Stock with respect to which the AHC
Preferred Stock is distributed (as determined,  for Axion  stockholders who hold
two or more blocks of stock with different bases, on a  block-by-block  approach
rather than by  aggregating  the bases of all blocks of stock held by each Axion
stockholder) and (iii) finally,  as gain from the sale of Axion Common Stock. In
addition,  Axion would incur certain  withholding  tax liabilities to the extent
such distributions were made to certain foreign individuals and entities.

<PAGE>
 

<PAGE>
   
               3. An Axion  stockholder's  aggregate  basis in the shares of AHC
Preferred Stock received in the  distribution  would equal the fair market value
of such shares,  and the  stockholder's  holding  period for such AHC  Preferred
Stock would not include the period  during  which the shares of Axion Stock were
held.

               Under the Tax Matters  Agreement,  the AHC  Indemnifying  Parties
have agreed to indemnify the BMS  Indemnified  Parties against any tax liability
arising from the failure of the  Distribution  to qualify as a tax-free  spinoff
under  Section  355 of the Code or any other tax  liabilities  arising  from the
Contributions,    the   Distribution   or   the   related   transactions.    See
"Indemnification Arrangements--Terms of the Tax Matters Agreement".

               The foregoing is included  herein for general  information  only.
Such  opinions are based in part on  representations  provided by Axion and BMS.
The  summary  does not  address  the  Federal  income  tax  consequences  to all
categories of Axion  stockholders,  including those who acquired shares of Axion
capital  stock  pursuant  to the  exercise  of stock  options  or  otherwise  in
compensatory transactions. EACH AXION STOCKHOLDER IS URGED TO CONSULT HIS OR HER
TAX  ADVISOR  AS TO  THE  SPECIFIC  TAX  CONSEQUENCES  TO  HIM  OR  HER  OF  THE
DISTRIBUTION,  INCLUDING THE APPLICATION AND EFFECT OF STATE,  LOCAL AND FOREIGN
INCOME AND OTHER TAX LAWS.
    

                                   RELATIONSHIP WITH BMS

               Following   the  Merger,   AHC  will  continue  to  have  certain
relationships with BMS and its subsidiaries.

               AHC and the 81%  Subsidiaries  (including  OPUS Sub),  the Former
Axion  Stockholders,   BMS,  the  Surviving  Corporation,  OPUS,  OTNC  and  the
Partnership will be parties to the  Indemnification  Agreement,  the Tax Matters
Agreement and the Escrow Agreement. See "Indemnification  Arrangements--Terms of
the  Indemnification  Agreement",  "--Terms  of the Tax Matters  Agreement"  and
"--Terms of the Escrow Agreement".

NONCOMPETITION AGREEMENTS

               Michael D. Goldberg, Garrett J. Roper, AHC and OnCare are subject
to separate  Noncompetition  Agreements with BMS. The Noncompetition  Agreements
will become  effective at Closing and will, for two years  following the Closing
Date,  prohibit such entities or persons and their  affiliates,  as the case may
be,  from,  as  applicable,  ownership,  management,  operation  or control  of,
employment  by, holding  certain  equity  interests in or serving as a director,
advisor or consultant to, or having certain other relationships with, any entity
that engages in the  distribution  of oncology  drugs,  supplies or biologics to
certain customers of OTN or the automated drug dispensing and inventory tracking
systems business in the United States. In addition,  each of the  Noncompetition
Agreements  provides  that  none of AHC or  OnCare  or any of  their  respective
subsidiaries  or Michael D.  Goldberg  or  Garrett  J.  Roper will  solicit  for
employment  or hire,  whether as an employee,  consultant  or  otherwise,  David
Levison,  President of OTNC,  during the term of his  employment  agreement with
OTNC.

AHC SUPPLY AGREEMENT; ONCARE SUPPLY AGREEMENT; AHC MEDSTATION AGREEMENT; ONCARE
MEDSTATION AGREEMENT

               Pursuant to the AHC Supply Agreement and OnCare Supply Agreement,
which  will  become   effective  at  the  Closing,   each  of  AHC  and  OnCare,
respectively,  will purchase  from OTN all the products and supplies  offered by
OTN required by all oncology  treatment  facilities that are either owned by AHC
or  OnCare,  as the case  may be,  or any of their  respective  subsidiaries  or
controlled  affiliates,  managed by AHC or OnCare, as the case may be, or any of
their respective  subsidiaries or controlled  affiliates or which AHC or OnCare,
as the  case may be,  or any of  their  respective  subsidiaries  or  controlled
affiliates  has  the  authority  at the  discretion  of the  oncology  treatment
facility to purchase  products or supplies.  In general OTN will provide each of
AHC and OnCare the lowest prices at which OTN sells such products or supplies to
other  oncology  physician  management
    


                                       45

companies with the authority to make purchasing decisions on behalf of physician
office  practices  which  have  agreed  to make  purchase  or  other  commercial
commitments  equivalent to those agreed to by AHC or OnCare, as the case may be,
provided that in the event AHC or OnCare,  as the case may be, receives an offer
pricing  products  or  supplies  at a price of at least 10% less than the lowest
price  offered by OTN and OTN  chooses  not to match such  lower  offer,  AHC or
OnCare,  as the case may be, may purchase such products or supplies  pursuant to
such lower  offer for a term to end upon the later of 30 days after the  receipt
of such  lower  offer and the term of such  lower  offer.  The  existing  supply
agreement between OTN and OnCare will terminate on the Closing Date.

               Similar  arrangements  have  been  made  between  each of AHC and
OnCare  and  OPUS  pursuant  to the AHC  Medstation  Agreement  and  the  OnCare
Medstation  Agreement,  respectively,  regarding  the  lease  from  OPUS of OPUS
Stations.  As of June 30, 1996, eight OPUS Stations were in use at six different
oncology practices operated by OnCare. The relevant OPUS Station agreements will
remain in effect after the Closing Date.

LICENSE AGREEMENT

               In the  License  Agreement,  AHC  will  agree to  provide  to the
Surviving Corporation a royalty-free exclusive,  fully paid up right and license
to use the "OPUS" name and other scheduled  intellectual  property in connection
with the OPUS Station  Business for a period of one year. The License  Agreement
also provides that the Surviving  Corporation may use certain  supplies  bearing
the "Axion" name as specified in the License  Agreement for a period of not more
than  two  months;  provided  that  the  Surviving  Corporation  agrees  to  use
commercially reasonable efforts to terminate its use of such supplies as soon as
practicable following the Effective Time.

TRANSITIONAL SERVICES AGREEMENT

               In the Transitional Services Agreement, AHC will agree to provide
to Axion certain services,  including certain financial and information  systems
services,  at cost, and the Surviving  Corporation  will agree to provide to AHC
certain services, including certain information systems services, at $15,000 per
month. The services provided under the Transitional  Services  Agreement will be
performed  for a period of three months after the date thereof with  renewals of
one month  upon the mutual  consent of the  parties  with such  renewals  not to
exceed an aggregate of three months in addition to the original term.


                              TRADING OF AHC PREFERRED STOCK

               There is no existing  trading market for AHC Preferred Stock. AHC
has not sought and does not intend to apply for listing of AHC  Preferred  Stock
on a securities  exchange or seek  approval for  quotation  through an automated
quotation system. There can be no assurance that any trading market will develop
for AHC Preferred Stock.

               The AHC Preferred Stock received by Axion  stockholders  pursuant
to the Distribution will not be freely transferable under the Securities Act. In
addition,  the AHC  Certificate  of  Incorporation  will be amended prior to the
Distribution  to  provide  for  various  restrictions  on  transfer  of the  AHC
Preferred  Stock.  AHC Preferred Stock will not be  transferable  except for (i)
transfers to AHC; (ii) transfers to existing AHC  stockholders;  (iii) transfers
by gift  bequest or  operation  of the laws of  descent,  provided  that the AHC
Preferred  Stock in the  hands of the  transferee  remains  subject  to the same
restrictions  on  transfer  as  they  were  when  held by the  transferor;  (iv)
transfers  to  an  entity   unaffiliated   with  AHC  pursuant  to  the  merger,
consolidation,  stock for stock exchange or similar  transaction  involving AHC;
(v) transfers by a partnership to its partners,  provided that the AHC Preferred
Stock in the hands of the transferee remains subject to the same restrictions on
transfer  as they were when held by the  transferor;  and (vi)  transfers  which
would  be  exempt  from  the  registration  requirements  of  Section  5 of  the
Securities  Act by virtue  of the  exemption  provided  by  Section  4(2) of the
Securities  Act if the  transferor  were the issuer of the AHC Preferred  Stock,
provided that the transferee is an "accredited  investor"  within the meaning of
Rule 501(a) under the Securities Act and the AHC Preferred Stock in the hands of
such  transferee  remains  subject to the same  restrictions on transfer as they
were  when  held by the  transferor,  or a  transfer  pursuant  to an  effective
registration under the Securities Act. In addition, the Restated AHC Certificate
and  Restated  AHC Bylaws  provide

    


                                       46

for  the  same  restrictions  on  transfer to be placed on AHC Common Stock once
such stock is issued.  Holders of AHC  Preferred Stock will be permitted to sell
their  AHC Preferred  Stock received  pursuant to the Distribution only pursuant
to an effective  registration statement under the Securities  Act or pursuant to
an exemption from registration, such as the exemptions afforded by Section  4(2)
of  the  Securities  Act   and   Rule  144 thereunder.  The  stock  certificates
evidencing   the   AHC   Preferred   Stock  will bear legends referring to  such
restrictions.

                                      CAPITALIZATION

               The following table summarizes the consolidated capitalization of
AHC and OPUS Matrix Business as of June 30, 1996 on a historical  basis and also
on a pro forma basis. The pro forma presentation  reflects:  (i) the transfer by
Axion to AHC of certain  assets,  including  all cash and cash  equivalents  and
short-term  investments and the final distribution of the Preference Amount from
the  Partnership to Axion net of Retained Cash (which is assumed to equal zero),
and the OnCare Preferred Stock; (ii)  reconstituting the OPUS Matrix Business as
a subsidiary of AHC; and (iii) the elimination of non-interest  bearing advances
from Axion and affiliates,  all as a contribution to the capital of AHC. The pro
forma presentation also reflects the  recapitalization of AHC in which 9,970,509
shares of AHC  Preferred  Stock are  expected to be issued in  exchange  for and
cancelation  of the 1,000 shares of AHC Common Stock  outstanding as of June 30,
1996.

                            REPORT OF INDEPENDENT AUDITORS


The Board of Directors
Axion Inc.

We have audited the accompanying combined balance sheet of Axion HealthCare Inc.
(including  OPUS  Matrix) as of December  31,  1995,  and the  related  combined
statements of operations and accumulated  deficit and net capital deficiency and
cash  flows  for  the  year  then  ended.  These  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audit.

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

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the combined financial position of Axion HealthCare Inc.
(including  OPUS Matrix) at December 31, 1995,  and the combined  results of its
operations  and its cash  flows  for the year then  ended,  in  conformity  with
generally accepted accounting principles.

1.  FORMATION, OWNERSHIP AND BUSINESS

Axion  HealthCare  Inc.  ("AHC") was  incorporated  in December 1994 as a wholly
owned  subsidiary  of  Axion  Inc.  ("Axion")  but had no  operations  in  1994.
Effective January 1, 1995, AHC commenced  operations.  These operations included
the  continuation of a clinical studies program begun by Axion in 1987. Axion is
a  cancer-focused  healthcare  service  firm  whose  principal  business  is the
distribution  of  oncology  drugs  and  related  products  to U.S.  office-based
oncologists.  The  pharmaceutical  distribution  business is conducted through a
partnership (the "Partnership") with Bristol-Myers Squibb Company ("BMS").

AHC provides  cancer-specific  managed  care  services to cancer care payers and
providers. AHC will provide services and information tools specifically designed
to assist in better managing  cancer care from both a clinical  quality and cost
standpoint.  AHC is in the early stages of development  and has derived  limited
revenues to date from such services.

As described in Note 3, Axion and BMS have entered into an agreement and plan of
merger and,  immediately prior thereto,  Axion intends to distribute to its then
stockholders all of the outstanding  shares of stock in AHC.  Included among the
net  assets  and  business  of AHC at the date of  distribution  will be the net
assets  of the OPUS  Matrix  business  and the  management  information  systems
operations  (together  "OPUS  Matrix") of OPUS  Health  Systems  Inc.  ("OPUS"),
another  subsidiary  of Axion.  The OPUS  Matrix  Business  consists of computer
software which provides  office-based oncology practices with access to drug and
treatment  information.  OPUS Matrix also consists of the management information
systems to  support  Axion's  business.  OPUS  Matrix is in the early  stages of
development and has not derived any revenues to date.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

2.  ACCOUNTING POLICIES

BASIS OF PRESENTATION

The  accompanying   financial  statements  include  the  combined  accounts  and
operating  results of AHC and OPUS Matrix.  From inception to date, AHC and OPUS
Matrix,  as part of OPUS,  have been  subsidiaries  of Axion.  During that time,
Axion  incurred  certain  expenses on behalf of AHC and OPUS  Matrix.  Allocated
charges  for  these  expenses  have been  reflected  in the  combined  financial
statements.

UNAUDITED FINANCIAL STATEMENTS

The  financial  statements  at June 30, 1996 and for the six month periods ended
June 30,  1996 and  1995  are  unaudited.  In the  opinion  of  management,  all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included. Operating results for the six-month period
ended June 30, 1996 are not  necessarily  indicative  of the results that may be
expected for the year ended December 31, 1996.

USE OF ESTIMATES

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial  statements and accompanying notes.
Actual results could differ from those estimates.

REVENUES

Revenues have been derived  primarily from clinical  outcome services and cancer
prevention studies, and such revenues are recognized as the services and studies
are provided.  Revenues also include the sale of a software license,  related to
software developed for use by Opus Matrix.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
          (IN THOUSANDS OF DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

           (Information at June 30, 1996 and for the six months ended
                      June 30, 1995 and 1996 is unaudited)


SOFTWARE DEVELOPMENT

Under an agreement  with  Electronic  Data  Systems  Corporation  ("EDS"),  OPUS
receives  information  technology  services  for its  operations  and  also  for
software  development  related  to its OPUS  Matrix  product  line.  Under  this
agreement,  OPUS Matrix reflected  $1,180 as part of general and  administrative
costs in 1995.  No further  services  are expected to be provided by EDS to OPUS
Matrix.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost and depreciated using the straight-line
method  over  the  estimated  useful  lives,  primarily  five  years.  Leasehold
improvements are amortized by the straight-line method over the estimated useful
lives or the lease term, whichever is less.

INCOME TAXES

The Company  accounts for income taxes using the  liability  method.  Using this
method,  deferred  tax  liabilities  and  assets  are to be  recognized  for the
expected future tax consequences of temporary  differences  between the carrying
amounts and the tax bases of assets and liabilities.

An income tax benefit has been  recognized for the use in the  consolidated  tax
return of Axion of the operating losses of AHC and OPUS Matrix.

3. PROPOSED  MERGER OF  AXION AND  BMS AND DISTRIBUTION OF THE OUTSTANDING STOCK
   OF AHC TO STOCKHOLDERS OF AXION

As of August 2, 1996, Axion and BMS signed an amended and restated agreement and
plan of merger,  which  contemplates  the merger of a newly formed  wholly owned
subsidiary of BMS into Axion, with Axion being the surviving company. Holders of
shares of Axion's common stock at the  consummation of the proposed merger would
receive  shares of common  stock of BMS  having an  aggregate  value at  $86,000
subject to a holdback of shares of common stock of BMS having a value of $5,000.
The  $5,000  in  shares of  common  stock of BMS plus  $5,000 in cash  otherwise
available  to AHC will  constitute  an  escrow  fund to  secure  indemnification
obligations to BMS in the event BMS

                     NOTES TO COMBINED FINANCIAL STATEMENTS
          (IN THOUSANDS OF DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

           (Information at June 30, 1996 and for the six months ended
                      June 30, 1995 and 1996 is unaudited)


were to suffer certain defined indemnifiable losses.  Consummation of the merger
of Axion and the newly formed BMS subsidiary requires approval by the holders of
Axion's  various  classes  of  stock.  Consummation  also  is  conditioned  upon
satisfactory  completion  of certain U.S.  regulatory  matters and certain other
conditions.

Immediately prior to consummation of the merger,  Axion intends to distribute to
its then stockholders all of the outstanding  shares of stock of AHC, which will
represent  100%  ownership  in AHC.  Prior to that  distribution,  AHC will have
received from Axion, as a contribution to the capital of AHC,  substantially all
of Axion's  assets and  liabilities  other  than  those  assets and  liabilities
related to Axion's  interest in the Partnership  and the OPUS Station  automated
drug dispensing business. Among the more significant assets to be transferred to
AHC by Axion will be: (i) a cash  distribution  from the Partnership to Axion of
$13,615,  subject to  adjustment  in certain  situations,  and the  remainder of
Axion's cash and cash equivalents and short-term investments ($2,485 at June 30,
1996),  subject to  adjustment  in certain  situations,  of which $5,000 will be
placed in an escrow fund; (ii) the shares of Series A redeemable preferred stock
of OnCare  (2,700,000  shares with a redemption value and cost of $13,500);  and
(iii) amounts due under loans extended to those persons  exercising  Axion stock
options and warrants  (none at June 30, 1996, but  approximately  $6,500 at that
date had  substantially  all of the options and warrants then  outstanding  been
exercised and loans extended for the full exercise  price).  None of those items
had been  transferred to AHC as of June 30, 1996. None has been reflected in its
combined balance sheet at that date.

4.  PRO FORMA CONDENSED BALANCE SHEET

The  following  pro forma  condensed  balance sheet gives effect to the transfer
from Axion to AHC,  as a  contribution  to the  capital  of AHC,  of: (i) a cash
distribution from the Partnership to Axion of $13,615 (which would have required
additional  borrowings  of $12,915 at that date),  and the  remainder of Axion's
cash and cash equivalents and short-term  investments ($2,485 at June 30, 1996),
subject to adjustment in certain  situations,  of which $5,000 will be placed in
an escrow fund; and (ii) $13,500  redemption and carrying value of the 2,700,000
shares of Series A redeemable preferred stock of OnCare. The pro forma condensed
balance sheet does not reflect the exercise of  unexercised  Axion stock options
and warrants or the transfer of loans  receivable and cash received thereby from
Axion to AHC.  The pro forma  condensed  balance  sheet also gives effect to the
elimination  of  the  existing  intercompany  indebtedness  due  Axion  and  its
affiliates,  the amount of which was $3,563 at June 30, 1996,  as an  additional
contribution to the capital of AHC.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
          (IN THOUSANDS OF DOLLARS, EXCEPT SHARE AND PER SHARE AMOUNTS)

           (Information at June 30, 1996 and for the six months ended
                      June 30, 1995 and 1996 is unaudited)



      As a  consolidated  subsidiary of Axion,  AHC has been allocated an income
tax  benefit  for the use of its  losses  in  Axion's  consolidated  income  tax
returns.  Had the distribution of the shares of common stock of AHC been made at
January 1, 1995, no such benefit would have been allocated to AHC.

5.  INTEREST IN ONCARE TO BE TRANSFERRED TO AHC

OnCare,  formed  by  Axion  in  June  1995  is an  oncology  physician  practice
management  company. On December 31, 1995, Axion distributed all of its holdings
of the  common  stock of OnCare to the  stockholders  of  Axion,  including  the
holders of shares of  preferred  and common stock and the holders of options and
other  rights to  acquire  shares of common  stock,  and  OnCare  ceased to be a
consolidated  subsidiary of Axion.  Axion retained a $3,500 interest in OnCare's
Series A redeemable  preferred  stock and in February  and March 1996  increased
that  interest to $13,500.  OnCare is obligated to redeem the Series A preferred
stock at a redemption price of $5 per share at the earlier of December 31, 1996,
the closing of a qualifying  underwritten public offering of the common stock in
OnCare, the merger or consolidation of OnCare with or into another  corporation,
or the  sale of all or  substantially  all of  OnCare's  assets.  The  condensed
financial  position  of  OnCare  at June 30,  1996 and  Axion's  interest  to be
transferred to AHC are summarized as follows:


6.  Subsequent Event

On  September 10, 1996, Axion agreed to extend the final date for the redemption
of the OnCare preferred stock from December 31, 1996 to December 31, 2000.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                            (IN THOUSANDS OF DOLLARS)
   
               The following  discussion  contains  forward-looking  statements.
AHC's  actual  results  could  differ  materially  from those  discussed  in the
forward-looking  statements.  Factors  that could  cause or  contribute  to such
differences  include those  discussed  below and  elsewhere in this  Information
Statement, particularly in "Special Factors".
    
OVERVIEW

               Neither AHC nor the OPUS Matrix Business has realized significant
revenues to date.  Both have  operated and  continue to operate at a loss.  Both
have been dependent upon Axion to finance their development activities.

RESULTS OF OPERATIONS
   
               Revenues  ($970 in 1995;  $253 and $104 in the six month  periods
ended June 30, 1995 and 1996,  respectively)  have been derived  primarily  from
clinical  outcomes  services  and cancer  prevention  studies  done by AHC and a
software license sold by the OPUS Matrix Business.

               Costs and expenses ($3,257 in 1995;  $1,644 and $2,374 in the six
month  periods  ended  June  30,  1995  and  1996)  have  represented  primarily
management  information  systems  costs for AHC and OPUS,  software  development
costs of the OPUS Matrix  products,  clinical  studies costs incurred by AHC and
administrative  costs  incurred by both AHC and Opus Matrix,  including  amounts
charged  by Axion for  administrative  services.  Such  amounts  have  increased
primarily due to development costs of the OPUS Matrix products.

               AHC and the OPUS Matrix  Business have been allocated  income tax
credits by Axion for the  benefits  arising from  inclusion  of their  operating
losses in the consolidated income tax returns of Axion.

               The AHC Business has generated  limited revenues and has incurred
losses  since AHC's  formation  in 1994.  The OPUS Matrix  Business has incurred
losses since its inception in 1994.

LIQUIDITY

               Axion has provided the funds used by both AHC and the OPUS Matrix
Business for their development activities since inception. Advances by Axion and
other affiliates of Axion amounted to $1,572 in 1995 and an additional $1,991 in
the six months ended June 30,  1996.  There can be no  assurance  that  adequate
funding  will be  available  to AHC from  Axion or any  other  source.  Axion is
expected not to provide funding to AHC after the Distribution and the Merger.

               Prior  to the  planned  distribution  of  all of the  outstanding
shares of stock of AHC  (including  OPUS  Matrix),  Axion intends to transfer to
AHC: (i) a cash  distribution of the Preference  Amount from OTN to OTNC and, in
turn, from OTNC to Axion of $13,615,  and the remainder of Axion's cash and cash
equivalents  and  short-term  investments  ($2,485  at June  30,  1996)  (net of
Retained Cash,  which is assumed to equal zero) subject to adjustment in certain
situations  of which  $5,000 will be placed in an escrow  fund;  (ii)  2,700,000
shares of OnCare Preferred Stock (with a redemption value of $13,500); and (iii)
receivables  from the Employee  Loans  (estimated to be  approximately  $6,500).
These cash and cash equivalents and short-term  investments  balances plus other
assets  transferred  to AHC will be used to assist the  financing of its ongoing
operations and for general corporate purposes.  The restrictive  covenants under
the  Indemnification  Agreement  and  the  existence  of  potentially  unlimited
indemnification obligations may restrict the ability of AHC to obtain financing,
and there can be no assurance that AHC will have the ability to obtain financing
(or that the failure to obtain financing will not have a material adverse effect
on  AHC).  AHC  believes  that the cash  and  cash  equivalents  and  short-term
investments  it will hold  immediately  after the Merger should be sufficient to
satisfy its cash needs through the end of 1997, assuming no
    
                                       62

<PAGE>


   
indemnification  payments  from AHC to BMS in excess of the Escrowed Cash and no
release of Escrowed Cash to AHC. Subject to such  assumptions,  the Company does
not  anticipate  that it will attempt to seek financing from other sources prior
to the end of such  period.  See  Note 3 to  consolidated  financial  statements
elsewhere herein.

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


(1)     Each of the options listed in the table is immediately exercisable.  The
        shares purchasable  thereunder are subject to repurchase by Axion at the
        original exercise price paid per share upon the optionee's  cessation of
        service prior to vesting in such shares. The repurchase right lapses and
        the  options  vest in a series  of 72 equal  monthly  installments.  The
        option shares will vest in full upon an  acquisition  of Axion by merger
        or asset sale,  including the Merger.  Each option has a maximum term of
        ten (10)  years,  subject  to  earlier  termination  in the event of the
        optionee's  cessation  of  employment  or  service  with  Axion  or  its
        affiliates.
    
(2)     The exercise  price may be paid in cash, in shares of Axion Common Stock
        valued at fair market value on the  exercise  date or through a cashless
        exercise  procedure  involving a same-day sale of the purchased  shares.
        Axion may also  finance  the option  exercise  by loaning  the  optionee
        sufficient  funds to pay the exercise  price for the  purchased  shares,
        together with any federal and state income tax liability incurred by the
        optionee in connection with such exercise.
   
(3)     The  5%  and  10%  assumed  annual  rates  of  compounded   stock  price
        appreciation  are mandated by rules of the  Commission.  There can be no
        assurance  provided  to any  executive  officer  or any other  holder of
        Axion's  securities  that the actual stock price  appreciation  over the
        10-year  option  term will be at the assumed 5% and 10% levels or at any
        other  defined  level.  Unless the market  price of Axion  Common  Stock
        appreciates  over the option  term,  no value will be realized  from the
        option grants made to the executive officers.

(2)     Certain of the options are  immediately  exercisable  for option  shares
        (noted by an asterisk in the table),  but any shares purchased under the
        options will be subject to repurchase by Axion at the original  exercise
        price per share upon the optionee's cessation of service. The repurchase
        right  has  lapsed as to the  following  number of shares as of June 30,
        1996: Mr. Goldberg:  62,500; Dr. Herfindal:  31,250; Mr. Roper:  25,000.
        The repurchase  right lapses in a series of 72 monthly  installments and
        will fully lapse upon an  acquisition  of Axion by merger or asset sale,
        including the Merger.


1995 EXECUTIVE STOCK OPTION PLAN

               Axion's 1995 Executive  Stock Option Plan (the "Axion 1995 Plan")
was  adopted  by  the  Axion  Board  on  April  4,  1995,  and  approved  by the
stockholders  on June 7, 1995.  600,000  shares of Axion  Common Stock have been
authorized  for  issuance  under the Axion 1995 Plan.  As of June 30,  1996,  no
shares had been issued under the Axion 1995 Plan, options for 600,000 shares had
been granted and were  outstanding and no shares  remained  available for future
grant.  Shares of Axion Common Stock subject to outstanding options which expire
or terminate  prior to exercise will be available for future  issuance under the
Axion 1995 Plan. The Merger  Agreement  provides,  however,  that from August 2,
1996 until  consummation  of the Merger or termination of the Merger  Agreement,
Axion will not, nor will it permit any of its  subsidiaries to, issue any shares
of capital stock or rights, warrants or options to purchase any such shares. See
"The  Merger--Covenants"  in  the  Proxy   Statement/Prospectus  to  which  this
Information Statement is attached as Appendix G.

               Under the Axion 1995 Plan,  employees  who are  officers of Axion
may, at the discretion of the plan administrator, be granted options to purchase
shares of Axion Common  Stock.  The exercise  price may be more or less than the
fair  market  value of such  shares on the grant  date.  The Axion  1995 Plan is
administered by the Axion Board.

               The exercise price for options  granted under the Axion 1995 Plan
may be paid in cash or in outstanding shares of Axion Common Stock.  Options may
also be exercised on a cashless  basis through the sameday sale of the purchased
shares,  provided  the  Axion  Common  Stock is then  registered  under  Federal
securities  laws.  The  Axion  Board may also  permit  the  optionee  to pay the
exercise price through a promissory note payable in  installments  over a period
of years.  The amount  financed  may  include  any  Federal or state  income and
employment taxes incurred by reason of the option exercise.

               Each option  includes a special  stock  appreciation  right which
provides that, upon the acquisition of 50% or more of Axion's outstanding voting
stock pursuant to a hostile tender offer,  when Axion's  officers are subject to
the short-swing profit restrictions of the Federal securities laws, such option,
if  outstanding  for at least six  months,  will  automatically  be  canceled in
exchange  for a cash  distribution  to the officer  based upon the tender  offer
price.

               The Axion Board has the  authority to effect,  from time to time,
the  cancelation of outstanding  options under the Axion 1995 Plan in return for
the grant of new options for the same or different  number of option shares with
an exercise price per share based upon the fair market value of the Axion Common
Stock on the new grant date. The Merger Agreement provides,  however,  that from
August 2, 1996 until  consummation  of the Merger or  termination  of the Merger
Agreement,  Axion will not, nor will it permit any of its subsidiaries to, issue
any shares of capital stock or rights,  warrants or options to purchase any such
shares. See "The  Merger--Covenants" in the Proxy  Statement/Prospectus to which
this Information Statement is attached as Appendix G.

               In the event Axion is acquired by merger, consolidation,  reverse
merger or asset sale,  the shares of Axion Common  Stock  subject to each option
outstanding at the time under the Axion 1995 Plan will immediately vest in full.
Options  not  exercised  prior to the Merger  will  terminate.  The Merger  will
constitute a corporate  transaction under the Axion 1995 Plan and therefore will
result in acceleration of the  exercisability of all options and the accelerated
lapsing of the repurchase  right under all  outstanding  options.  Axion options
will not be assumed in connection with the Merger and Axion's  repurchase  right
will not be assigned in connection with the Merger.

               The Axion  Board may amend or modify  the Axion  1995 Plan at any
time.  The Axion  1995 Plan  will  terminate  on April 3,  2005,  unless  sooner
terminated by the Axion Board.

1989 STOCK OPTION AND RESTRICTED STOCK PLAN

               The Axion 1989 Stock Option and Restricted Stock Plan (the "Axion
1989 Plan") was adopted by the Axion Board of  Directors  on February  21, 1990,
and approved by the  stockholders  on February 21, 1990. The Axion 1989 Plan has
been amended on several occasions, most recently on August 10, 1994, to increase
the number of shares issuable  thereunder by 1,000,000  shares,  and on April 4,
1995,  to add an automatic  option grant  program.  Two million  shares of Axion
Common Stock have been  authorized for issuance under the Axion 1989 Plan. As of
June 30, 1996, 266,596 shares had been issued under the Axion 1989 Plan, options
for 1,105,215  shares had been granted and were  outstanding  and 628,189 shares
remained  available for future  grants of options.  Shares of Axion Common Stock
subject to outstanding  options which expire or terminate prior to exercise will
be available for future issuance under the Axion 1989 Plan. The Merger Agreement
provides,  however, that from August 2, 1996 until consummation of the Merger or
termination of the Merger  Agreement,  Axion will not, nor will it permit any of
its  subsidiaries  to, issue any shares of capital stock or rights,  warrants or
options to purchase any such shares.  See "The  Merger--Covenants"  in the Proxy
Statement/Prospectus to which this Information Statement is attached as Appendix
G.

               Under  the  Axion  1989  Plan,  employees  (including  officers),
non-employee  members of the Board and  independent  consultants of Axion or its
subsidiaries  may,  at the  discretion  of the plan  administrator,  be  granted
options to purchase  shares of Axion Common Stock at an exercise  price not less
than 85% of the fair  market  value of such  shares on the grant  date or issued
shares  directly for  consideration  which may consist of cash or past  services
rendered to Axion or its subsidiaries.  Non-employee  members of the Axion Board
are also  eligible for automatic  option  grants under the Axion 1989 Plan.  The
Axion 1989 Plan is administered by the Axion Board.

               The exercise price for options  granted under the Axion 1989 Plan
may be paid in cash or in outstanding shares of Axion Common Stock.  Options may
also be exercised on a cashless  basis through the sameday sale of the purchased
shares, provided the Axion Common Stock is publicly traded.

               Each  option  granted  to an  officer  of  Axion  subject  to the
short-swing  profit  restrictions  of the  Federal  securities  laws  includes a
special stock  appreciation  right which provides that,  upon the acquisition of
50% or more of Axion's  outstanding  voting stock  pursuant to a hostile  tender
offer, such option, if outstanding for at least six months,  will  automatically
be canceled in exchange for a cash  distribution  to the officer  based upon the
tender offer price.

               The Axion Board has the  authority to effect,  from time to time,
the  cancelation of outstanding  options under the Axion 1989 Plan in return for
the grant of new options for the same or different  number of option shares with
an exercise price per share based upon the fair market value of the Axion Common
Stock on the new grant date. The Merger Agreement provides,  however,  that from
August 2, 1996 until  consummation  of the Merger or  termination  of the Merger
Agreement,  Axion will not, nor will it permit any of its subsidiaries to, issue
any shares of capital stock or rights,  warrants or options to purchase any such
shares. See "The  Merger--Covenants" in the Proxy  Statement/Prospectus to which
this Information Statement is attached as Appendix G.

               In the event Axion is acquired by merger,  consolidation or asset
sale  ("corporate  transaction"),  options  granted after August 10, 1994,  will
terminate  unless assumed by the successor  corporation;  options granted before
that date accelerate and then terminate upon a corporate  transaction unless the
option is assumed by the successor corporation. The shares of Axion Common Stock
awarded under the Axion 1989 Plan,  including  unvested  shares  purchased  upon
exercise  of  an  option,  will  immediately  vest  in  full  upon  a  corporate
transaction,  except to the extent  Axion's  repurchase  rights with  respect to
those  shares are to be  assigned  to the  acquiring  entity.  The  Merger  will
constitute a corporate  transaction under the Axion 1989 Plan and therefore will
result in acceleration of the  exercisability of all pre-August 10, 1994 options
and the  accelerated  lapsing  of the  repurchase  right  under all  outstanding
options.  Axion  options will not be assumed in  connection  with the Merger and
Axion's repurchase right will not be assigned in connection with the Merger.

               Under the automatic grant program,  each individual  serving as a
non-employee  director on April 4, 1995, and each individual who first joins the
Axion Board as a  non-employee  director on or after that date,  will receive an
automatic option grant for 10,000 shares of Axion Common Stock. In addition,  on
April 1 each year  beginning  April 1, 1996,  each  non-employee  director  will
automatically  be  granted a stock  option to  purchase  10,000  shares of Axion
Common  Stock,  provided  such  individual  has served on the Axion Board for at
least six months  prior to such date.  Each option  will have an exercise  price
equal to the fair market value of the Axion Common Stock on the automatic  grant
date and a maximum term of ten years,  subject to earlier termination  following
the optionee's  cessation of Axion Board service. The option will be immediately
exercisable  for all of the shares but the shares will be subject to  repurchase
at  original  cost.  The  repurchase  right shall lapse and the shares vest in a
series of 48 monthly  installments  over the  optionee's  period of Axion  Board
service, beginning one month from the grant date, subject to accelerated lapsing
upon a corporate transaction.

               In the event  that more than 50% of  Axion's  outstanding  voting
stock were to be acquired  pursuant to a hostile  tender offer,  each  automatic
option  grant  which  has  been  outstanding  for at  least  six  months  may be
surrendered to Axion in return for a cash distribution from Axion based upon the
tender  offer price per share of Axion  Common  Stock at the time subject to the
surrendered option.

               The Axion  Board may amend or modify  the Axion  1989 Plan at any
time.  The Axion 1989 Plan will  terminate on February 20, 2000,  unless  sooner
terminated by the Axion Board.

                 SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
                              AND MANAGEMENT OF AHC

               All of the  outstanding  shares of AHC Common Stock are, and will
be prior to the  Distribution,  held  beneficially  and of record by Axion.  The
following table sets forth certain information regarding beneficial ownership of
Axion's Common Stock as of July 31, 1996, (i) by each person who is known by AHC
to beneficially own more than five percent of Axion's common stock, (ii) by each
of AHC's directors and executive  officers,  and (iii) by all current  directors
and executive officers as a group.  Because the Distribution will be made on the
basis of one share of AHC  Preferred  Stock for each  share of then  outstanding
Axion  Common  Stock,  the  percentage  ownership of each person or entity named
below immediately  following the Distribution will be the same as the percentage
ownership of such person or entity immediately prior to the Distribution.

          EXECUTIVE COMPENSATION PLANS IN EFFECT AFTER THE DISTRIBUTION

               Set out below is a description of the principal  employee benefit
and compensation  plans of AHC that will be in effect following the Distribution
and the Merger and in which Mr. Goldberg, Dr. Herfindal and Mr. Roper, the three
Named  Officers,  will  participate.  Also set out below is a description of the
effect  of  the  Distribution  and  Merger  on  certain  of the  existing  plans
maintained  by Axion in which  the Named  Officers  currently  participate.  Mr.
Levison will not  participate  in plans of AHC after the Merger but was eligible
to participate in plans  maintained by Axion and will be eligible to participate
in plans of BMS or its subsidiaries for which he is eligible after the Merger.

401(K) PLAN

               AHC expects to maintain a 401(k) Plan to be effective at the Time
of Distribution  for the eligible  employees of AHC. The 401(k) Plan will permit
salary  deferral   contributions   and  employer  matching  and  profit  sharing
contributions  at the  discretion  of AHC.  Account  balances  held on behalf of
employees of AHC under the existing  Axion 401(k) Plan will be  transferred in a
trustee-to-trustee transfer from the Axion 401(k) Plan to AHC's 401(k) Plan.

ANNUAL INCENTIVE AWARDS

               In past years,  the Axion Board has approved  bonuses  payable in
cash or stock to the  officers and key  employees of Axion.  Bonuses are accrued
quarterly  and paid annually  based on the eligible  employee's  achievement  of
individual  goals  specified  by the Axion Board,  in the case of officers,  and
specified by management, in the case of other employees.  Payment of bonuses and
eligibility  for bonuses is subject to the  discretion  of the Axion Board.  AHC
maintains a comparable  bonus plan. AHC anticipates  that it will pay bonuses at
the end of the 1996 fiscal year to the employees who continue in employment with
AHC for services performed during the 1996 fiscal year. Bonuses are generally in
proportion  to base salary and normally fall within a range of 5% to 40% of base
salary.

OTHER FEATURES OF STOCK PLANS AND PREDECESSOR PLANS

               Options  outstanding under the Axion 1989 Plan and the Axion 1995
Plan will terminate upon  consummation of the Merger to the extent not exercised
prior to the Merger.

               Consistent  with the Axion 1989 Plan and the Axion 1995 Plan, the
Axion  Board  intends  to loan to each  optionee,  including  each of the  Named
Officers,  the sum of money  necessary  to  exercise  his or her  stock  options
granted  under the  Axion  1989 Plan or Axion  1995  Plan and will  receive  the
optionee's full recourse  promissory  note. Such note may or may not be secured.
Each such note shall bear interest at the applicable Federal rate established by
the IRS and shall be due at the end of two years, subject to acceleration to the
extent the optionee sells any of the Axion Common Stock  purchased with the note
or the BMS shares  received in exchange for such Axion Common Stock.  Such notes
will be contributed by Axion to AHC pursuant to the Distribution.

               Upon  exercise  of an option  under the Axion  1989 Plan or Axion
1995 Plan, each optionee, including each of the Named Officers, will participate
as a stockholder in the  Distribution  and accordingly will receive one share of
the Series A  Preferred  Stock of AHC on  account of each share of Axion  Common
Stock owned by such individual as of the  Distribution  Record Date. In the case
of shares of Axion Common Stock and Axion  Options that are not yet vested as of
the date of the  Distribution,  the optionees must agree,  in  consideration  of
being  permitted to exercise such options by delivering a promissory  note, that
the shares of AHC  Preferred  Stock will be  subject to  repurchase  by AHC at a
price equal to the fair market value of the AHC  Preferred  Stock on the date of
the spinoff in the event that the holder's  employment  terminates prior to full
vesting.  AHC's  repurchase  right will lapse and the optionee  will vest in the
shares in a series of  installments  over the term of the  individual's  service
with AHC, with credit for service at Axion.

AHC INDEMNIFICATION AGREEMENTS

               It is  anticipated  that  AHC  will  enter  into  indemnification
agreements with its directors and officers.  These  agreements will require that
AHC, among other things,  indemnify its directors and officers  against  certain
liabilities  that arise by reason of their  status or service  as  directors  or
officers (other than liabilities arising from actions not taken in good faith or
in a manner the  indemnitee  believed  to be in the best  interests  of AHC) and
advance their expenses incurred as a result of any proceeding against them as to
which they could be  indemnified.  The Restated AHC Certificate and Restated AHC
Bylaws will provide,  as applicable,  for the  indemnification  of directors and
officers and the  exculpation  under certain  circumstances  of  directors.  See
"Comparison  of Certain  Rights of Holders of AHC  Preferred  Stock,  Holders of
Axion  Common  Stock and Holders of Axion  Preferred  Stock--Indemnification  of
Officers and Directors".


                        DESCRIPTION OF AHC CAPITAL STOCK

AUTHORIZED CAPITAL STOCK

               The  authorized  capital  stock  of  AHC  currently  consists  of
15,000,000  shares of Common Stock,  $.0001 par value,  and 5,000,000  shares of
Preferred Stock, $.0001 par value.

               In  accordance  with  the  Distribution  Agreement,   Axion  will
appropriately  cause AHC to amend its  Certificate  of  Incorporation  in effect
prior to the Distribution to, among other things, increase the authorized number
of shares of AHC  Preferred  Stock and to convert  each  issued and  outstanding
share of AHC Common Stock into a number of shares of AHC  Preferred  Stock equal
to the quotient of (A) the number of shares of Axion  Common  Stock  outstanding
immediately  prior to the Time of  Distribution  (including  any shares of Axion
Common Stock issued in connection  with the conversion of Axion  Preferred Stock
to Axion  Common  Stock  and the  exercise  of Axion  Options,  in each  case in
connection with the consummation  of the  Merger) divided  by (B) the  number of
shares  of  AHC  Common  Stock  outstanding  immediately  prior to  the  Time of
Distribution.  See  "The  Distribution--Terms  of the  Distribution  Agreement".
Under the Restated AHC Certificate, the total number of shares of all classes of
stock that  AHC will have  authority to issue  is 20,000,000 of which 10,000,000
may be shares of AHC Common Stock.

               Based on the number of shares of Axion Common  Stock  outstanding
as of June 30, 1996 (and assuming the exercise of all Axion Options  outstanding
immediately  prior to the Time of  Distribution  other than the Goldberg  $10.00
Options),  it is estimated that approximately  9,970,509 shares of AHC Preferred
Stock will be distributed to Axion  stockholders in the Distribution.  No shares
of the Axion Preferred  Stock were  outstanding at July 31, 1996. All the shares
of  AHC  Preferred  Stock  to  be  distributed  to  Axion  stockholders  in  the
Distribution will be fully paid and non-assessable.

               The following summary describes material  provisions of, but does
not purport to be complete and is subject to, and  qualified in its entirety by,
the  Restated  AHC  Certificate  attached  as Annex I hereto  and by  applicable
provisions of law.

AHC COMMON STOCK

               As of July 31, 1996,  there were 1,000 shares of AHC Common Stock
outstanding.  There  will be no shares of AHC  Common  Stock  outstanding  after
giving effect to the Distribution.

               Holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding  Preferred  Stock, any holders of Common Stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the Board of Directors out of funds legally available  therefor.  See
"Dividends and Dividend  Policy".  In the event of  liquidation,  dissolution or
winding up of AHC, any holders of Common Stock are entitled to share  ratably in
all assets remaining after payment of liabilities, subject to prior distribution
rights of Preferred  Stock,  if any, then  outstanding.  The Common Stock has no
preemptive  or  conversion  rights or other  subscription  rights.  There are no
    
                                       73

redemption  or sinking  fund  provisions  applicable  to the Common  Stock.  All
outstanding  shares of Common  Stock are fully paid and  nonassessable,  and the
shares of Common Stock to be issued upon  completion  of this  offering  will be
fully paid and nonassessable.

AHC PREFERRED STOCK

               The  Restated AHC  Certificate  authorizes  10,000,000  shares of
Preferred Stock. The AHC Board has the authority to issue the Preferred Stock in
one  or  more  series  and  to  fix  the  rights,  preferences,  privileges  and
restrictions  thereof,  including  dividend rights,  dividend rates,  conversion
rights,  voting rights,  terms of  redemption,  redemption  prices,  liquidation
preferences and the number of shares  constituting any series or the designation
of such series, without further vote or action by the stockholders. The issuance
of Preferred  Stock may have the effect of delaying,  deferring or  preventing a
change in control of AHC  without  further  action by the  stockholders  and may
adversely affect the voting and other rights of the holders of Common Stock. The
issuance of  Preferred  Stock with voting and  conversion  rights may  adversely
affect the voting power of the holders of Common  Stock,  including  the loss of
voting  control to others.  At present,  AHC has no plans to issue any series of
Preferred Stock other than AHC Preferred Stock.

               Upon  consummation  of the  Distribution,  the  holders  of Axion
Common Stock will become holders of AHC Preferred  Stock. In accordance with the
Distribution  Agreement,  Axion  will  cause  AHC to amend  the  Certificate  of
Incorporation of AHC to establish certain rights,  preferences and privileges of
the AHC Preferred Stock. The AHC Preferred Stock will not be redeemable.

               Holders of AHC  Preferred  Stock will be entitled to one vote per
share  on all  matters  to be voted  upon by the  stockholders  and will  have a
liquidation preference of $3.00 plus all declared but unpaid dividends per share
in the event of any  liquidation,  dissolution or winding up of AHC and are paid
before any payments are made to any holders of AHC Common Stock.  Subject to the
rights  of  series  of  Preferred  Stock  that may from  time to time  come into
existence,  any holders of Preferred  Stock will be entitled to receive  ratably
such  dividends  at a rate of $.21 per  share  per  annum  out of funds  legally
available therefor, prior and in preference to any declaration or payment of any
dividend  (payable other than in AHC Common Stock or other securities and rights
convertible  into or  entitling  the holder  thereof  to  receive,  directly  or
indirectly,  additional shares of AHC Common Stock) on the AHC Common Stock. See
"Dividends  and  Dividend  Policy".  Each share of AHC  Preferred  Stock will be
convertible  at any time and from time to time at the option of the holder  into
one share of AHC Common Stock,  subject to  adjustments  for among other things,
stock splits and stock  dividends.  AHC Preferred Stock will not be transferable
except as permitted in the Restated AHC  Certificate:  AHC Preferred  Stock will
not be transferable  except for (i) transfers to AHC; (ii) transfers to existing
AHC  stockholders;  (iii)  transfers by gift bequest or operation of the laws of
descent,  provided that the AHC Preferred  Stock in the hands of the  transferee
remains  subject to the same  restrictions on transfer as they were when held by
the transferor;  (iv) transfers to an entity  unaffiliated  with AHC pursuant to
the  merger,  consolidation,  stock for stock  exchange  or similar  transaction
involving AHC; (v) transfers by a partnership to its partners, provided that the
AHC Preferred  Stock in the hands of the transferee  remains subject to the same
restrictions  on  transfer  as they were when held by the  transferor;  and (vi)
transfers which would be exempt from the registration  requirements of Section 5
of the Securities Act by virtue of the exemption provided by Section 4(2) of the
Securities  Act if the  transferor  were the issuer of the AHC Preferred  Stock,
provided that the transferee is an "accredited  investor"  within the meaning of
Rule 501(a) under the Securities Act and the AHC Preferred Stock in the hands of
such  transferee  remains  subject to the same  restrictions on transfer as they
were  when  held by the  transferor,  or a  transfer  pursuant  to an  effective
registration under the Securities Act.

NO PREEMPTIVE RIGHTS

               No holder of any stock of any class of AHC authorized at the Time
of  Distribution  will  then  have  any  preemptive  right to  subscribe  to any
securities of any kind or class.

DESCRIPTION OF CERTAIN CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS

        NUMBER OF DIRECTORS; REMOVAL; VACANCIES

               The  Restated  AHC  Certificate   provides  that  the  number  of
directors  will be determined  from time to time by a majority of the AHC Board.
The AHC Board is currently comprised of three directors. The Restated AHC Bylaws
provide  that only the AHC Board will be entitled to fill  vacancies,  including
vacancies created by expansion of the AHC Board.

               The Restated AHC Bylaws  provide  that  directors  may be removed
with or without cause by the holders of a majority of shares entitled to vote at
an election of directors.

        STOCKHOLDER ACTION BY UNANIMOUS CONSENT; SPECIAL MEETINGS

               The Restated AHC Bylaws  provide that  stockholder  action may be
taken at an annual or special  meeting of  stockholders  and that  action may be
taken by the written consent of stockholders in lieu of a meeting.  The Restated
AHC Bylaws also  provide  that  special  meetings of AHC's  stockholders  may be
called  pursuant  to a  resolution  approved by a majority of the AHC Board or a
majority of AHC's stockholders.

        AMENDMENT OF CERTAIN CHARTER AND BYLAW PROVISIONS

               The  Restated  AHC  Certificate  provides  that the AHC Board may
make, repeal,  alter, amend or rescind any provision of the Restated AHC Bylaws.
The Restated AHC Bylaws provide that Bylaw provisions may be adopted, amended or
repealed by the affirmative  vote of a majority of stockholders who are entitled
to cast votes.

        PREFERRED STOCK

               Under the Restated AHC  Certificate,  the AHC Board will have the
authority  to provide by  resolution  for the  issuance of shares of one or more
series of AHC Preferred  Stock and to fix the terms and  conditions of each such
series.  See  "Description of AHC Capital Stock".  The authorized  shares of AHC
Preferred  Stock, as well as authorized but unissued shares of AHC Common Stock,
will be available for issuance  without  further  action by AHC's  stockholders,
unless  stockholder  action is required by  applicable  law or by the rules of a
stock exchange on which any series of AHC's stock may then be listed.

               These provisions will give the AHC Board the power to approve the
issuance of a series of AHC Preferred Stock that could,  depending on its terms,
either impede or facilitate  the  completion of a merger,  tender offer or other
takeover  attempt.  For  example,  the  issuance  of new shares  might  impede a
business  combination  if the terms of those shares  include voting rights which
would enable a holder to block business combinations.  Conversely,  the issuance
of new shares  might  facilitate  a business  combination  if those  shares have
general  voting  rights  sufficient  to  cause  an  applicable  percentage  vote
requirement to be satisfied.

INDEMNIFICATION

               The Restated AHC Certificate  provides that an AHC director shall
not be personally  liable to AHC or its  stockholders  for monetary  damages for
breach of fiduciary duty as a director,  except for liability (i) for any breach
of the director's duty of loyalty to AHC or its  stockholders,  (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation  of  law,  (iii)  under  Section  174 of the  DGCL,  or  (iv)  for any
transaction from which the director derived any improper personal  benefit.  Any
repeal or modification of the preceding sentence by the stockholders of AHC will
not  adversely  affect any right or  protection of a director of AHC existing at
the time of such repeal or modification.

               DGCL  Section 145  contains  provisions  permitting,  and in some
situations   requiring,   Delaware   corporations,   such  as  AHC,  to  provide
indemnification  to their  officers  and  directors  for losses  and  litigation
expenses  incurred in connection  with their service to the corporation in those
capacities.   The  Restated  AHC  Bylaws
    


                                       75

will contain provisions requiring  indemnification by AHC of, and advancement of
expenses to, its directors and officers to the fullest extent  permitted by law.
Among other things,  these  provisions  will provide  indemnification  for AHC's
officers and directors  against  liabilities for judgments in and settlements of
lawsuits  and other  proceedings  and for the  advance  and  payment of fees and
expenses  reasonably  incurred by the director or officer in defense of any such
lawsuit or proceeding.

               The form of the Restated AHC  Certificate and Restated AHC Bylaws
are  attached  to  this   Information   Statement  as  Annex  I  and  Annex  II,
respectively,   and  are  incorporated   herein  by  reference.   The  foregoing
descriptions of certain  provisions of the Restated AHC Certificate and Restated
AHC Bylaws does not purport to be complete and are subject to, and are qualified
in entirety by  reference  to, the  Restated  AHC  Certificate  and Restated AHC
Bylaws, respectively, including the definitions therein of certain terms.










                         COMPARISON OF CERTAIN RIGHTS OF
          HOLDERS OF AHC PREFERRED STOCK, HOLDERS OF AXION COMMON STOCK
                      AND HOLDERS OF AXION PREFERRED STOCK

               The rights of the holders of AHC Preferred Stock will be governed
by the Restated AHC Certificate  and the Restated AHC Bylaws.  The rights of the
holders of Axion Common Stock and holders of Axion  Preferred Stock are governed
by the Axion  Certificate of  Incorporation  and the Axion Bylaws.  Both AHC and
Axion  are  governed  by  the  DGCL.  Upon  consummation  of  the  Merger,   the
stockholders  of  Axion  will  become  stockholders  of AHC.  The  Restated  AHC
Certificate  and the Restated AHC Bylaws will remain in effect after the Merger.
Below is a summary  of  certain  differences  among the rights of holders of AHC
Common  Stock,  the  holders  of Axion  Common  Stock and the  holders  of Axion
Preferred Stock,  resulting from differences in governing law and the respective
AHC and Axion certificates of incorporation and bylaws.

               The following summary does not purport to be a complete statement
of the rights of AHC  stockholders  under the Restated AHC  Certificate  and the
Restated  AHC Bylaws  compared  with the rights of holders of Axion Common Stock
and  holders  of  Axion   Preferred   Stock  under  the  Axion   Certificate  of
Incorporation and the Axion Bylaws. This summary is qualified in its entirety by
reference to the  respective AHC and Axion  certificates  of  incorporation  and
bylaws.

VOTING

               The  Restated  AHC  Certificate  provides  that  holders  of  AHC
Preferred Stock are entitled to one vote for each share held.

               The Axion  Certificate of Incorporation  provides that holders of
Axion Common Stock are entitled to one vote for each share held.

               The Axion  Certificate of Incorporation  provides that holders of
Axion Preferred Stock are entitled to the number of votes equal to the number of
shares of Axion  Common  Stock into which such shares of Axion  Preferred  Stock
could  be  converted  on the  record  date  for  the  vote  or the  date  of the
solicitation of any written consent of Axion stockholders  (excluding fractional
shares) and shall have voting  rights and powers equal to the voting  rights and
powers of holders of Axion Common Stock.  Holders of Axion  Preferred Stock vote
together  as a single  class  with the  holders of Axion  Common  Stock upon all
matters  submitted to a vote of Axion  stockholders.  The Axion  Certificate  of
Incorporation  also  provides  for  certain  matters  specified  therein  to  be
submitted to a vote of holders of Axion  Preferred  Stock,  voting in some cases
together as a single class and in other cases separately by series.

LIQUIDATION PREFERENCE

               The Restated AHC  Certificate  provides  that in the event of any
liquidation,  dissolution or winding up of AHC,  subject to the rights of series
of Preferred Stock of AHC that may from time to time come into
    


                                       76

existence, the holders of AHC Preferred Stock are entitled to receive, prior and
in  preference  to any  distribution  of any assets of AHC to the holders of AHC
Common Stock by reason of their ownership thereof,  for the AHC Preferred Stock,
an amount per share equal to the sum of (A) $3.00 for each outstanding  share of
AHC Preferred Stock, and (B) an amount equal to declared but unpaid dividends on
such share.  If upon the  occurrence  of such  event,  the assets and funds thus
distributed  among the holders of the AHC Preferred  Stock are  insufficient  to
permit the payment to such holders of the full aforesaid  preferential  amounts,
then  subject  to the rights of series of  Preferred  Stock of AHC that may from
time to time come into  existence,  the entire  assets and funds of AHC  legally
available for distribution shall be distributed ratably among the holders of the
AHC Preferred  Stock,  so that each holder  receives the same  percentage of the
applicable preferential amount.

               The Axion  Certificate of Incorporation  does not provide holders
of Axion  Common  Stock  with any  liquidation  preference  in the  event of any
liquidation, dissolution, or winding up of Axion.

               The Axion Certificate of Incorporation provides that in the event
of any liquidation,  dissolution,  or winding up of Axion,  whether voluntary or
involuntary,  the  holders  of each  share of  Axion  Preferred  Stock  shall be
entitled  to  be  paid  out  of  the  assets  of  Axion  legally  available  for
distribution to its stockholders the following liquidation preferences: $.75 per
share of Axion Series A Preferred  Stock,  par value $.001 per share (the "Axion
Series A"), $3.40 per share of Axion Series B Preferred  Stock,  par value $.001
per share (the "Axion  Series B"),  $4.79 per share of Axion  Series C Preferred
Stock,  par value  $.001 per share (the "Axion  Series  C"),  $5.60 per share of
Axion  Series D Preferred  Stock,  par value $.001 per share (the "Axion  Series
D"),  $7.25 per share of Axion  Series E  Preferred  Stock,  par value $.001 per
share (the "Axion  Series E"),  and $10.00 per share of Axion Series F Preferred
Stock,  par value $.001 per share (the "Axion  Series F", and together  with the
Axion  Series A, Axion Series B, Axion Series C, Axion Series D and Axion Series
E, the "Axion Preferred  Stock"),  plus, for each such share, an amount equal to
all  declared  but  unpaid  dividends  thereon,  if any,  to the date  fixed for
distribution  to such  series  (such sum,  subject to certain  adjustments,  the
"Axion Preference Amount").

               After holders of Axion  Preferred  Stock have received their full
Axion Preference  Amount, any remaining assets or surplus funds of Axion will be
shared by and  distributed  ratably  among the holders of Axion Common Stock and
the holders of Axion Preferred Stock;  provided,  however, that holders of Axion
Series A, Axion  Series B, Axion  Series C, and Axion  Series E are  entitled to
participate  in such  ratable  distribution  and sharing only until such time as
they receive certain  aggregate per share maximum amounts set forth in the Axion
Certificate of Incorporation.

               For  purposes of the  foregoing  two  paragraphs  relating to the
liquidation rights of Axion Preferred Stockholders, a merger or consolidation of
Axion into or with another corporation, a sale, transfer or other disposition of
all or  substantially  all of Axion's assets or the  effectuation  by Axion of a
transaction  or series of  related  transactions  in which  more than 50% of the
voting  power of Axion is  disposed  of,  shall,  unless the holders of at least
66-2/3% of the Axion  Preferred  Stock,  voting  together  as a class,  elect in
writing otherwise,  be deemed to be a liquidation,  dissolution or winding up of
Axion.

               In the event  Axion  proposes  to take any action  regarding  the
liquidation,  dissolution  or  winding  up  of  Axion  which  will  involve  the
distribution  of  assets  other  than  cash,  the  value  of  the  assets  to be
distributed to the holders of Axion  Preferred  Stock is to be determined by the
vote or  written  consent of the Axion  Board  (subject  to  certain  guidelines
specified  in  the  Axion  Certificate  of  Incorporation  with  respect  to the
valuation  of  securities),  and such  determination  will be  binding  upon the
holders of Axion Preferred Stock.

DIVIDENDS

               The Restated AHC Certificate  provides that subject to the rights
of  series  of  Preferred  Stock of AHC that may  from  time to time  come  into
existence,  the  holders of AHC  Preferred  Stock  shall be  entitled to receive
dividends, out of any assets legally available therefor, prior and in preference
to any declaration or payment of any dividend  (payable other than in AHC Common
Stock or other  securities and rights  convertible  into or entitling the holder
thereof to receive,  directly  or  indirectly,  additional  shares of AHC Common
Stock) on the AHC Common Stock,  at the rate of $.21 per share per annum for the
AHC Preferred Stock.

               The Axion Certificate of Incorporation  provides that the holders
of the outstanding  Axion Series A, Axion Series B, Axion Series C, Axion Series
D, Axion Series E and Axion Series F are entitled to receive in any fiscal year,
when and as declared by the Axion  Board,  out of any assets at the time legally
available  therefor,  dividends in cash at the rate of $.075 per share, $.34 per
share,  $.42 per  share,  $.56 per  share,  $.725  per share and $1.00 per share
respectively (subject to adjustment),  per annum before any dividend is declared
or paid on  shares  of Common  Stock.  Dividends  may be  payable  quarterly  or
otherwise as the Axion Board may from time to time  determine,  and the right to
such dividends is not cumulative. The holders of the outstanding Axion Preferred
Stock can waive any  dividend  preference  that such  holders may be entitled to
receive upon the affirmative  vote or written consent of the holders of at least
66-2/3% of the Axion Preferred Stock then outstanding, voting or consenting as a
single class on an  as-if-converted  basis. The holders of the outstanding Axion
Preferred Stock have  unconditionally  and  irrevocably  waived the right to any
such  dividend  preference  that such  holders are  entitled to receive  through
December 31, 1996.

               The  Axion   Certificate  of   Incorporation   provides  that  no
distributions (as defined in the Axion Certificate of Incorporation) may be paid
on the Axion Common Stock until the holders of the  outstanding  Axion Preferred
Stock have first  received  dividends  at the  dividend  rates  specified in the
preceding paragraph. If, in any fiscal year, any cash or other distributions are
declared  by the Axion  Board to be paid on the Axion  Common  Stock as a class,
then an additional  dividend must be paid at the same time to the holders of the
outstanding  Axion Preferred Stock at the rate per share equal to the product of
(x) such per share  dividend or other  distribution  on the Axion Common  Stock,
multiplied  by (y) the  number of shares of Axion  Common  Stock into which each
share of Axion Preferred Stock is then convertible.



CONVERSION RIGHTS

               The  Restated  AHC  Certificate  provides  that each share of AHC
Preferred  Stock is convertible at any time,  without  payment of any additional
consideration by the holder and at the option of the holder, into one fully paid
and nonassessable share of AHC Common Stock,  subject to adjustment.  Each share
of AHC Preferred  Stock will  automatically  be converted  into one share of AHC
Common  Stock upon the  earlier of (i) AHC's sale of AHC Common  Stock in a firm
commitment  underwritten public offering pursuant to a registration statement on
Form S-1 under the  Securities  Act, the public  offering price of which was not
less than  $10,000,000  in the  aggregate or (ii) the date  specified by written
consent or agreement of the holders of a majority of the then outstanding shares
of AHC Preferred Stock.

               The Axion Common Stock is not convertible.

               The Axion  Certificate of Incorporation  provides that each share
of Axion Preferred Stock is convertible at any time,  without the payment of any
additional  consideration  by the holder and at the option of the  holder,  into
such number of fully paid and  nonassessable  shares of Axion Common Stock as is
determined  according  to a  formula  set  forth  in the  Axion  Certificate  of
Incorporation,  subject to adjustment.  Each share of Axion Preferred Stock will
automatically  be converted  into shares of Axion Common Stock at the applicable
conversion  price then in effect upon the affirmative vote or written consent of
the holders of at least 66-2/3% of the Axion Preferred  Stock then  outstanding,
voting or consenting as a single class on an  as-if-converted  basis.  Axion may
not, by  amendment  of the Axion  Certificate  of  Incorporation  or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities  or any other  voluntary  action,  avoid or seek to avoid the
observance  or  performance  of any of the  terms of the  Axion  Certificate  of
Incorporation  relating  to  conversion  and must take all action  necessary  or
appropriate  in order to protect the  conversion  rights of the holders of Axion
Preferred Stock against impairment.

CERTAIN BUSINESS COMBINATIONS

               The Restated AHC Certificate requires the affirmative vote of the
holders  of more  than  50% of the  outstanding  shares  of stock of AHC for any
transaction  that  would  result in a  reorganization  of AHC,  or the merger or
consolidation  of AHC with or into another  corporation,  or the effectuation by
AHC of a transaction or series of  transactions  resulting in the disposition of
more than 50% of the voting power of AHC.

Axion  Series  C,  Axion  Series  D,  Axion  Series  E or  Axion  Series  F  are

effectuation  by Axion of a transaction or series of  transactions in which more
than 50% of the voting  power of Axion is disposed  of, Axion or the sale of all
or  substantially  all of the assets of Axion must be approved by the holders of
at least 50% of the then outstanding  shares of Axion Preferred Stock (excluding
from such vote the shares of any series of Axion  Preferred Stock of which there
are fewer than 100,000 shares outstanding), voting together as a single class.

SIZE AND CLASSIFICATION OF THE BOARD OF DIRECTORS

               The AHC Board  currently  consists of three  directors and is not
classified. The number of authorized directors may be modified from time to time
by amendment of the Restated AHC Bylaws

               The Axion Board  currently  consists of six  directors and is not
classified. The number of authorized directors may be modified from time to time
by amendment of the Axion Bylaws.


REMOVAL OF DIRECTORS

               The  Restated  AHC  Bylaws  provide  that  the AHC  Board  or any
individual director may be removed from office, with or without cause, by a vote
of stockholders  holding a majority of outstanding shares entitled to vote at an
election of directors.

               The  Axion  Bylaws   provide  that,  at  a  special   meeting  of
stockholders called for such purpose, the Axion Board or any individual director
may be  removed  from  office,  with or without  cause,  and a new  director  or
directors  elected  by  a  vote  of  stockholders  holding  a  majority  of  the
outstanding shares entitled to vote at an election of directors.

VACANCIES ON THE BOARD OF DIRECTORS

               The Restated AHC Bylaws  provide that vacancies and newly created
directorships  resulting from any increase in the authorized number of directors
may be filled by a majority of the directors then in office,  although less than
a quorum,  or by a sole  remaining  director,  and each director so elected will
hold  office  until the next annual  election  and until his  successor  is duly
elected and qualified.

               The  Axion  Bylaws  provide  that  vacancies  and  newly  created
directorships  resulting from any increase in the authorized number of directors
may be filled by a majority of the directors then in office,  although less than
a quorum,  or by a sole  remaining  director,  and each director so elected will
hold office for the  unexpired  portion of the term of the director  whose place
shall be vacant and until his successor is duly elected and qualified. Vacancies
are deemed to exist in the case of the  death,  removal  or  resignation  of any
director,  or if the  stockholders  fail at any meeting of stockholders of which
directors  are to be elected to elect the number of directors  constituting  the
entire Axion Board.

               Under  the  Axion  Certificate  of  Incorporation,   any  vacancy
occurring because of the death, resignation, or removal of a director elected by
the holders of Axion  Series A, the holders of Axion  Series B or the holders of
Axion Series C will be filled by the vote or written consent of the holders of a
majority  of the shares of that series or, in the absence of such action by such
holders,  by action of the  remaining  directors  then in  office.  Any  vacancy
occurring because of the death,  resignation or removal of a director elected by
the  holders of  outstanding  Axion  Common  Stock will be filled by the vote or
written consent of the holders of a majority of the outstanding  shares of Axion
Common Stock or, in the absence of such action by such holders, by action of the
remaining directors then in office.

               The Restated AHC Certificate  requires approval by the holders of
at least 50% of the then outstanding  shares of AHC Common Stock or AHC Series A
Preferred  Stock,  as applicable,  for the addition,  amendment or repeal of any
provision of AHC's Restated AHC Certificate that would adversely alter or change
the preferences,  rights,  privileges or powers of the holders of such shares of
AHC Common Stock or AHC Series A Preferred Stock, as applicable. Notwithstanding
the previous sentence,  the Restated AHC Certificate  provides that AHC reserves
the right to amend,  alter,  change or repeal  any  provision  contained  in the

Notwithstanding  the previous  sentence,  the Axion Certificate of Incorporation
provides  that Axion  reserves the right to amend,  alter,  change or repeal any
provision contained in the Axion Certificate of Incorporation, in the manner now
or  hereafter   prescribed  by  statute  and  that  all  rights  conferred  upon

AMENDMENTS TO RESTATED AHC BYLAWS

               The Restated AHC Bylaws may be altered, amended or repealed by or
new Restated AHC Bylaws adopted by the AHC stockholders.  Under the Restated AHC
Bylaws,  the affirmative vote of stockholders  holding a majority of outstanding
shares entitled to vote is required to adopt,  amend or repeal any provisions of
the Restated AHC Bylaws.  Notwithstanding the preceding,  the AHC Board may from
time to time make, amend, supplement or repeal the Restated AHC Bylaws.

               The Axion  Bylaws  may be  repealed,  altered  or  amended or new
Restated Bylaws adopted by the Axion  stockholders.  Under the Axion Bylaws, the
affirmative  vote of the holders of at least  66-2/3% of the voting power of all
the then  outstanding  shares of the  capital  stock of Axion  entitled  to vote
generally in the election of directors,  voting  together as a single class,  is
required to adopt, amend or repeal any provisions of the Axion Bylaws. The Axion
Certificate of Incorporation  requires, so long as no fewer than an aggregate of
500,000  shares of Axion  Series A, Axion Series B, Axion Series C, Axion Series
D, Axion Series E or Axion Series F are outstanding, the approval of the holders
of at  least  50% of the  then  outstanding  shares  of  Axion  Preferred  Stock
(excluding  from such vote the shares of any series of Axion  Preferred Stock of
which there are fewer than 100,000  shares  outstanding),  voting  together as a
single class, to amend, repeal or add any provision to the Axion Bylaws, if such
action would adversely alter or change the  preferences,  rights,  privileges or
powers of, or the restrictions  provided for the benefit of, the Axion Preferred

omissions not in good faith or which involve intentional misconduct or a knowing
violation  or  law,  (iii)  under  Section  174 of the  DGCL,  or  (iv)  for any

                              AXION HEALTHCARE INC.

Corporation Law:

               "RESOLVED,   that  the  Certificate  of   Incorporation   of  the

                      1.     Dividend  Rights.  Subject to the rights of holders
of Preferred Stock,  when, as and if dividends or distributions  are declared on
the Common Stock,  whether  payable in cash, in property or in securities of the
Corporation, the holders of the Common Stock shall be entitled to share equally,
share for share,  in such  dividends as may be declared from time to time by the
Board of Directors,  when and as declared by the Board of Directors,  out of any
assets of the Corporation legally available therefor.

                      2.     Liquidation    Rights.    Upon   the   liquidation,
dissolution  or winding  up of the  corporation,  the assets of the  Corporation

                             a.     In  General.  The  holder  of each  share of
Common  Stock shall have the right to one vote,  and shall be entitled to notice

another corporation,  or the effectuation by the Corporation of a transaction or
series  of  transactions  in  which  more  than 50% of the  voting  power of the

the approval (by vote or written consent,  as provided by law) of the holders of
a majority of the then outstanding  shares of Common Stock, add, amend or repeal
any  provision  of  the  Corporation's   Amended  and  Restated  Certificate  of
Incorporation  that would  adversely  alter or change the  preferences,  rights,
privileges or powers of such shares.

               5.     Restrictions   on  Transfer.   Common  Stock  may  not  be
transferred except for:

                      a.     transfers to the Corporation;

                      b.     transfers to existing Corporation stockholders;

                      c.     transfers by gift, bequest or operation of the laws
of  descent,  provided  that the  Common  Stock in the  hands of the  transferee
remains subject to the same  restrictions on transfer as when it was held by the
transferor;

                      d.     transfers  to  an  entity   unaffiliated  with  the
Corporation pursuant to the merger,  consolidation,  stock for stock exchange or
similar transaction involving the Corporation;

                      e.     transfers  by  a   partnership   to  its  partners,
provided that the Common Stock in the hands of the transferee remains subject to
the same restrictions on transfer as when it was held by the transferor; or

                      f.     transfers   which   would   be   exempt   from  the
registration requirements of Section 5 of the Securities Act of 1933, as amended
(the "Act") by virtue of the  exemption  provided by Section  4(2) of the Act if
the transferor were the issuer of Common Stock,  provided that the transferee is
an "accredited investor" within the meaning of Rule 501(a) under the Act and the
Common  Stock  in the  hands  of such  transferee  remains  subject  to the same
restrictions  on transfer as when it was held by the  transferor,  or a transfer
pursuant to an effective registration under the Act.

               C. Preferred  Stock.  The Preferred Stock may be issued from time
to time in one or more  series.  The Board of  Directors  is hereby  authorized,
within  the  limitations  and   restrictions   stated  in  this  Certificate  of
Incorporation,  to fix or alter the dividend rights,  dividend rate,  conversion
rights,  voting rights,  rights and terms of redemption  (including sinking fund
provisions),  the redemption price or prices, and the liquidation preferences of
any  wholly  unissued  series  of  Preferred  Stock,  and the  number  of shares
constituting any such series and the designation thereof, or any of them, and to
increase or decrease the number of shares of any series  subsequent to the issue
of shares of that series, but not below the number of shares of such series then
outstanding.  In case the number of shares of any series shall be so  decreased,
the shares  constituting  such  decrease  shall resume the status which they had
prior to the adoption of the resolution  originally  fixing the number of shares
of such series. The rights, preferences,  privileges and restrictions granted to
and imposed on the Series A  Preferred  Stock,  which  series  shall  consist of
10,000,000 shares, are as set forth below in this Article IV(C).

               1. Dividend Rights.  Subject to the rights of Series of Preferred
Stock that may from time to time come into  existence,  the  holders of Series A
Preferred  Stock  shall be  entitled  to  receive  dividends,  out of any assets
legally  available  therefor,  prior and in  preference  to any  declaration  or
payment of any dividend  (payable other than in Common Stock or other securities
and rights convertible into or entitling the holder thereof to receive, directly
or

indirectly,  additional shares of Common Stock of the Corporation) on the Common
Stock of the Corporation, at the rate of $.21 per share per annum for the Series
A Preferred Stock.

               2.     Liquidation Preference.

                      a.     In the  event of any  liquidation,  dissolution  or
winding up of the  Corporation,  subject  to the  rights of series of  Preferred
Stock that may from time to time come into  existence,  the  holders of Series A
Preferred  Stock shall be entitled to receive,  prior and in  preference  to any
distribution  of any assets of the Corporation to the holders of Common Stock by
reason of their ownership  thereof,  for the Series A Preferred Stock, an amount
per share equal to the sum of (A) $3.00 for each  outstanding  share of Series A
Preferred  Stock,  and (B) an amount equal to declared  but unpaid  dividends on
such share.  If upon the  occurrence  of such  event,  the assets and funds thus
distributed  among  the  holders  of the  Series  A  Preferred  Stock  shall  be
insufficient  to  permit  the  payment  to such  holders  of the full  aforesaid
preferential  amounts,  then subject to the rights of series of Preferred  Stock
that may from time to time come into  existence,  the entire assets and funds of
the corporation  legally available for distribution shall be distributed ratably
among the holders of the Series A Preferred  Stock, so that each holder receives
the same percentage of the applicable preferential amount.

                      b.     Upon the completion of the distribution required by
subparagraph  (a) of this  Section  2 and any  other  distribution  that  may be
required  with respect to series of  Preferred  Stock that may from time to time
come into existence,  if assets remain in this  corporation,  the holders of the
Common Stock of this  corporation,  shall receive all of the remaining assets of
this Corporation.

               3.     Redemption.   The   Series  A   Preferred   Stock  is  not
redeemable.

               4.     Conversion.  The holders of the Series A  Preferred  Stock
shall have conversion rights as follows (the "Conversion Rights"):

                      a.     Right to Convert.  Each share of Series A Preferred
Stock shall be  convertible,  at the option of the holder  thereof,  at any time
after the date of issuance of such share,  at the office of this  Corporation or
any transfer agent for such stock,  into one share of Common Stock  (adjusted to
reflect subsequent stock dividends, stock splits or recapitalization).

                      b.     Automatic  Conversion.   Each  share  of  Series  A
Preferred  Stock shall  automatically  be converted  into shares of Common Stock
upon the  earlier of (i) the  Corporation's  sale of its Common  Stock in a firm
commitment  underwritten public offering pursuant to a registration statement on
Form S-1 under the Securities Act of 1933, as amended, the public offering price
of  which  was not  less  than  $10,000,000  in the  aggregate  or (ii) the date
specified  by written  consent or  agreement of the holders of a majority of the
then outstanding shares of Series A Preferred Stock.

                      c.     Mechanics  of  Conversion.  Before  any  holder  of
Series A  Preferred  Stock  shall be entitled to convert the same into shares of
Common Stock, he shall





                                        4

<PAGE>



surrender the certificate or certificates therefor, duly endorsed, at the office
of this  Corporation or of any transfer agent for the Series A Preferred  Stock,
and shall give written  notice to this  Corporation  at its principal  corporate
office,  of the election to convert the same and shall state therein the name or
names in which the certificate or certificates for shares of Common Stock are to
be issued. This Corporation shall, as soon as practicable thereafter,  issue and
deliver at such  office to such holder of Series A  Preferred  Stock,  or to the
nominee or nominees of such holder, a certificate or certificates for the number
of shares of Common Stock to which such holder  shall be entitled as  aforesaid.
Such conversion shall be deemed to have been made immediately prior to the close
of  business on the date of such  surrender  of the shares of Series A Preferred
Stock to be converted,  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 as of such date.
If the conversion is in connection with an  underwritten  offering of securities
registered  pursuant to the Securities  Act of 1933, the conversion  may, at the
option of any holder  tendering  Series A  Preferred  Stock for  conversion,  be
conditioned  upon the closing with the  underwriters  of the sale of  securities
pursuant to such offering,  in which event the person(s) entitled to receive the
Common Stock upon conversion of the Series A Preferred Stock shall not be deemed
to have converted such Series A Preferred Stock until  immediately  prior to the
closing of such sale of securities.

               5.     Voting Rights.

                      a.     In General.  Except as set forth below,  the holder
of each share of Series A Preferred  Stock shall have the right to one vote, and
shall be entitled to notice of any stockholders'  meeting in accordance with the
Bylaws of the  Corporation,  and shall be entitled to vote upon such matters and
in such manner as may be provided by law.

                      b.     Change in Control.  The affirmative vote of holders
of more  than  50% of the  outstanding  shares  of the  Corporation's  stock  is
required for any Change in Control.

                      c.     Covenants.  So  long  as any  shares  of  Series  A
Preferred Stock shall be outstanding,  the Corporation  shall not, without first
obtaining the approval (by vote or written  consent,  as provided by law) of the
holders  of a  majority  of the then  outstanding  shares of Series A  Preferred
Stock,  add,  amend or repeal any  provision  of the  Corporation's  Amended and
Restated  Certificate of Incorporation  that would adversely alter or change the
preferences, rights, privileges or powers of such shares.

               6.     Restrictions on Transfer. Series A Preferred Stock may not
be transferred except for:

                      a.     transfers to the Corporation;

                      b.     transfers to existing Corporation stockholders;

<PAGE>



                      c.     transfers  by gift bequest or operation of the laws
of  descent,  provided  that the  Series A  Preferred  Stock in the hands of the
transferee remain subject to the same restrictions on transfer as they were when
held by the transferor;

                      d.     transfers  to  an  entity   unaffiliated  with  the
Corporation pursuant to the merger,  consolidation,  stock for stock exchange or
similar transaction involving the Corporation;

                      e.     transfers  by  a   partnership   to  its  partners,
provided  that the  Series A  Preferred  Stock  in the  hands of the  transferee
remains  subject to the same  restrictions on transfer as they were when held by
the transferor; or

                      f.     transfers   which   would   be   exempt   from  the
registration  requirements  of  Section 5 of the Act by virtue of the  exemption
provided by Section 4(2) of the Act if the transferor  were the issuer of Series
A Preferred  Stock,  provided that the  transferee is an  "accredited  investor"
within the meaning of Rule 501(a) under the Act and the Series A Preferred Stock
in the hands of such  transferee  remains  subject to the same  restrictions  on
transfer as they were when held by the transferor,  or a transfer pursuant to an
effective registration under the Act.


                                    ARTICLE V

               Except   as   otherwise   provided   in   this   Certificate   of

amend and rescind any or all of the Bylaws of the Corporation.

                                   ARTICLE VI

               The number of  directors of the  Corporation  shall be fixed from

                                   ARTICLE VII

               Elections of directors  need not be by written  ballot unless the
Bylaws of the Corporation shall so provide.

                                  ARTICLE VIII

               Meetings of stockholders  may be held within or without the State
of Delaware, as the Bylaws may provide. The books of the Corporation may be kept

                                   ARTICLE IX

               A director of the Corporation  shall not be personally  liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director,  except for liability  (i) for any breach of the  director's
duty of  loyalty  to the  Corporation  or its  stockholders,  (ii)  for  acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law,  (iii) under Section 174 of the Delaware  General  Corporation
Law, or (iv) for any  transaction  from which the director  derived any improper
personal  benefit.  If the Delaware  General  Corporation  Law is amended  after
approval by the  stockholders  of this  Article to  authorize  corporate  action
further  eliminating or limiting the personal  liability of directors,  then the
liability of a director of the Corporation shall be eliminated or limited to the
fullest extent permitted by the Delaware General Corporation Law as so amended.

               Any repeal or  modification  of the foregoing  provisions of this
Article X by the stockholders of the Corporation  shall not adversely affect any
right or  protection  of a director of the  Corporation  existing at the time of
such repeal or modification.

                                    ARTICLE X

repeal any provision  contained in this  Certificate  of  Incorporation,  in the
manner now or hereafter  prescribed by statute,  and all rights  conferred  upon
stockholders herein are granted subject to this reservation.

               THIRD:  The Restated  Certificate of  Incorporation  as set forth
above  has  been  duly  adopted  by this  Corporation's  Board of  Directors  in
accordance with the provisions of Section 245 of the General Corporation Law.

               SECTION 11. Unless otherwise provided in the certificate of
incorporation, any action required to be taken at any annual or special meeting
of stockholders of the corporation, or any action which may be taken at any

the action so taken, shall be signed by the holders of outstanding stock having
not less than the minimum number of votes that would be necessary to authorize
or take such action at a meeting at which all shares entitled to vote thereon
were present and voted. Prompt notice of the taking of the corporate action

                                   ARTICLE III

of the directors then in office, though less than a quorum, or by a sole

unless sooner displaced. If there are no directors in office, then an election
of directors may be

                                                                               5

held in the manner provided by statute. If, at the time of filling any vacancy
or any newly created directorship, the directors then in office shall constitute
less than a majority of the whole board (as constituted immediately prior to any
such increase), the Court of Chancery may, upon application of any stockholder
or stockholders holding at least ten percent of the total number of the shares
at the time outstanding having the right to vote for such directors, summarily
order an election to be held to fill any such vacancies or newly created
directorships, or to replace the directors chosen by the directors then in
office.
               SECTION 3. The business of the corporation shall be managed by or
under the direction of its board of directors which may exercise all such powers
of the corporation and do all such lawful acts and things as are not by statute
or by the certificate of incorporation or by these bylaws directed or required

Delaware.
               SECTION 5. The first meeting of each newly elected Board of
Directors shall be held at such time and place as shall be fixed by the vote of
the stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present. In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
Board of Directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and
place as shall be specified in a notice given as hereinafter provided for
special meetings of the Board of Directors, or as shall be specified in a
written waiver signed by all of the directors.

president on two (2) days notice to each director by mail or forty-eight (48)
hours notice to each director either personally or by telegram; special meetings
shall be called by the president or secretary in like manner and on like notice
on the written request of two directors unless the board consists of only one
director, in which case special meetings shall be called by the president or
secretary in like manner and on like notice on the written request of the sole
director.
               SECTION 8. At all meetings of the board a majority of the
directors shall constitute a quorum for the transaction of business and the act
of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the certificate of incorporation. If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.
               SECTION 9. Unless otherwise restricted by the certificate of
incorporation of these bylaws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.
               SECTION 10. Unless otherwise restricted by the certificate of
incorporation or these bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of

conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and such participation
in a meeting shall constitute presence in person at the meeting.

                             COMMITTEES OF DIRECTORS

               SECTION 11. The Board of Directors may, by resolution passed by a
majority of the whole board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation. The board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee.
               In the absence of disqualification of a member of a committee,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member.
               Any such committee, to the extent provided in the resolution of
the Board of Directors, shall have and may exercise all the powers and authority
of the Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the bylaws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to

authorize the issuance of stock. Such committee or committees shall have such
name or names as may be determined from time to time by resolution adopted by
the Board of Directors.
               SECTION 12. Each committee shall keep regular minutes of its
meetings and report the same to the Board of Directors when required.

                            COMPENSATION OF DIRECTORS

               SECTION 13. Unless otherwise restricted by the certificate of
incorporation or these bylaws, the Board of Directors shall have the authority
to fix the compensation of directors. The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

                              REMOVAL OF DIRECTORS

               SECTION 14. Unless otherwise restricted by the certificate of
incorporation or bylaw, any director or the entire Board of Directors may be
removed, with or without cause, by the holders of a majority of shares entitled
to vote at an election of directors.

                                     NOTICES

               SECTION 1. Whenever, under the provisions of the statutes or of
the certificate of incorporation or of these bylaws, notice is required to be
given to any director or stockholder, it shall not be construed to mean personal
notice, but such notice may be given in writing, by mail, addressed to such
director or stockholder, at his address as it appears on the records of the
corporation, with postage thereon prepaid, and such notice shall be deemed to be
given at the

               SECTION 1. Every holder of stock in the corporation shall be
entitled to have a certificate, signed by, or in the name of the corporation by,

optional or other special rights of each class of stock or series thereof and
the qualifications, limitations or restrictions of such preferences and/or
rights.
               SECTION 2. Any of or all the signatures on the certificate may be
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is
issued, it may be issued by the corporation with the same effect as if he were
such officer, transfer agent or registrar at the date of issue.

                                LOST CERTIFICATES

               SECTION 3. The Board of Directors may direct a new certificate or

issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
and/or to give the corporation a bond in such sum as it may direct as indemnity

new certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

                               FIXING RECORD DATE

               SECTION 5. In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty nor less than ten days before the date of
such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

                             REGISTERED STOCKHOLDERS

               SECTION 6. The corporation shall be entitled to recognize the
exclusive right of a person registered on its books as the owner of shares to
receive dividends, and to vote as such owner, and to hold liable for calls and
assessments a person registered on its books as the owner of shares and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.


                           RESTRICTIONS ON TRANSFER

               SECTION 7. Stock of the corporation shall not be transferred

                          a. transfers to the corporation;

                          b. transfers to existing corporation stockholders;

                          c. transfers by gift, bequest or operation of the laws
of descent, provided that the stock in the hands of the transferee remains
subject to the same restrictions on transfer as when it was held by the
transferor;

                          d. transfers to an entity unaffiliated with the
corporation pursuant to the merger, consolidation, stock for stock exchange or
similar transaction involving the corporation;

                          e. transfers by a partnership to its partners,
provided that the stock in the hands of the transferee remains subject to the
same restrictions on transfer as when it was held by the transferor; or

                          f. transfers which would be exempt from the
registration requirements of Section 5 of the Securities Act of 1933, as amended
(the 'Act') by virtue of the exemption provided by Section 4(2) of the Act if
the transferor were the issuer of stock, provided that the transferee is an
'accredited investor' within the meaning of Rule 501(a) under the Act and the
stock in the hands of such transferee remains subject to the same restrictions
on transfer as when it was held by the transferor, or a transfer pursuant to an
effective registration under the Act.



                                MARKET STAND-OFF

               SECTION 8. In connection with any underwritten public offering by

                                                                              16

under the Act, including the corporation's initial public offering, no
stockholder of the corporation shall sell, make any short sale of, loan,
hypothecate, pledge, grant any option for the purchase of, or otherwise dispose
or transfer for value or otherwise agree to engage in any of the foregoing
transactions with respect to, shares of stock of the corporation without the
prior written consent of the corporation or its underwriters. Such restriction
(the "Market Stand-Off") shall be in effect for such period of time from and
after the effective date of the final prospectus for the offering as may be
requested by the corporation or such underwriters. In no event, however, shall
such period exceed one hundred eighty (180) days and the Market Stand-Off
shall in all events terminate two (2) years after the effective date of the
corporation's initial public offering.
               Any new, substituted or additional securities that are by reason
of any recapitalization or reorganization distributed with respect to the shares
of stock of the corporation shall be immediately subject to the Market
Stand-Off, to the same extent the shares of stock of the corporation on which
such new, substituted or additional securities are distributed are at such time
covered by such provisions.
               In order to enforce the Market Stand-Off, the corporation may
impose stop-transfer instructions with respect to the shares of stock of the
corporation until the end of the applicable stand-off period.

                                   ARTICLE VII

                                    DIVIDENDS

               SECTION 1. Dividends upon the capital stock of the corporation,
subject to the provisions of the certificate of incorporation, if any, may be
declared by the Board of Directors at any regular or special meeting, pursuant
to law. Dividends may be paid in cash, in property, or in shares of the capital
stock, subject to the provisions of the certificate of incorporation.
               SECTION 2. Before payment of any dividend, there may be set aside
out of any funds of the corporation available for dividends such sum or sums as
the directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purposes as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

                                     CHECKS

               SECTION 3. All checks or demands for money and notes of the

               SECTION 4. The fiscal year of the corporation shall be fixed by
resolution of the Board of Directors.

                                      SEAL

                                                                              18

Delaware". The seal may be used by causing it or a facsimile thereof to be
impressed or affixed or reproduced or otherwise.

                                 INDEMNIFICATION

               SECTION 6. The corporation shall, to the fullest extent
authorized under the laws of the State of Delaware, as those laws may be amended
and supplemented from time to time, indemnify any director made, or threatened
to be made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation. The indemnification provided for in this Section 6
shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in their official
capacities and as to action in another capacity while holding such office, (ii)
continue as to a person who has ceased to be a director, and (iii) inure to the
benefit of the heirs, executors and administrators of such a person. The
corporation's obligation to provide indemnification under this Section 6 shall
be offset to the extent of any other source of indemnification or any otherwise
applicable insurance coverage under a policy maintained by the corporation or
any other person.
               Expenses incurred by a director of the corporation in defending a
civil or criminal action, suit or proceeding by reason of the fact that he is or
was a director of the corporation (or was serving at the corporation's request
as a director or officer of another corporation) shall be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon

                                                                              19

receipt of an undertaking by or on behalf of such director to repay such amount
if it shall ultimately be determined that he is not entitled to be indemnified
by the corporation as authorized by relevant sections of the General Corporation
Law of Delaware. Notwithstanding the foregoing, the corporation shall not be
required to advance such expenses to an agent who is a party to an action, suit
or proceeding brought by the corporation and approved by a majority of the Board
of Directors of the corporation which alleges willful misappropriation of
corporate assets by such agent, disclosure of confidential information in
violation of such agent's fiduciary or contractual obligations to the
corporation or any other willful and deliberate breach in bad faith of such
agent's duty to the corporation or its stockholders.
               The foregoing provisions of this Section 6 shall be deemed to be
a contract between the corporation and each director who serves in such capacity
at any time while this bylaw is in effect, and any repeal or modification
thereof shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.
               The Board of Directors in its discretion shall have power on
behalf of the corporation to indemnify any person, other than a director, made a
party to any action, suit or proceeding by reason of the fact that he, his
testator or intestate, is or was an officer or employee of the corporation.
               To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been "fiduciaries" of any employee benefit plan of the corporation
which may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Section

                                                                              20

6, be interpreted as follows: an "other enterprise" shall be deemed to include
such an employee benefit plan, including without limitation, any plan of the
corporation which is governed by the Act of Congress entitled "Employee
Retirement Income Security Act of 1974," as amended from time to time; the
corporation shall be deemed to have requested a person to serve an employee
benefit plan where the performance by such person of his duties to the
corporation also imposes duties on, or otherwise involves services by, such
person to the plan or participants or beneficiaries of the plan; excise taxes
assessed on a person with respect to an employee benefit plan pursuant to such
Act of Congress shall be deemed "fines."

                                  ARTICLE VIII

                                   AMENDMENTS

               SECTION 1. These bylaws may be altered, amended or repealed or
new bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the certificate of
incorporation at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal or adoption of new
bylaws be contained in the notice of such special meeting. If the power to
adopt, amend or repeal bylaws is conferred upon the Board of Directors by the
certificate or incorporation it shall not divest or limit the power of the
stockholders to adopt, amend or repeal bylaws.

                               STATEMENT OF FACTS

Axion Inc.  ("Distributing")  was  incorporated  under  Delaware law in 1987, as
Access  Biotechnology,  Inc.,  and  changed  its name to Axion in 1994.  Through
subsidiaries,  Distributing  is engaged in the  Clinical/Disease  Management and
Distribution Businesses, described more fully below.

The Clinical/Disease Management Business

Board of Directors                                                        Page 3
                                                              September 11, 1996







The   Clinical/Disease   Management   Business  is  a   collection   of  related
cancer-focused  healthcare  activities  designed  to  promote  provision  of the
highest quality  cost-effective  cancer care by office-based  oncologists.  This
business began upon  Distributing's  incorporation  in 1987 through its clinical
studies  activity.  This activity,  which continues to the present,  consists of
coordinating  the study of emerging  cancer  drugs and  treatments  developed by
pharmaceutical  and  biotechnology  companies.  A  significant  contribution  of
Distributing  in this area is its ability,  through its  relationships  with the
Southwest  Oncology Group and others, to facilitate these studies on patients in
doctor's  offices.  Depending  on the  particular  item,  the company  will help
develop the  parameters of the study,  negotiate  the  contract,  act as project
manager, provide logistical support (such as ordering,  receiving,  tracking and
disbursing drug shipments, and tracking patient sign-ups and responses), receive
and disburse payments, collect and analyze the data, and prepare a report of the
results.  The drug utilization  data developed is likely the most  comprehensive
available  in the  industry.  Revenues  are  derived  from  contracts  with drug
companies and practice groups.

The information and  relationships  developed in the clinical  studies  activity
have  resulted  in the  provision  of other  services,  largely to  office-based
oncologists,  including  reimbursement  assistance,  preparation of Federal Drug
Administration  applications,  practice  management,  and  (through  OPUS Health
Systems,  described below),  inventory management.  Moreover,  its knowledge and
experience  have  enabled  the  company to develop  cancer  drug  protocols  and
treatment  guidelines  which serve as integral  parts of its disease  management
program. In this activity,  began in 1993, the company negotiates with payers to
manage the delivery of cancer care. In this regard,  the company has developed a
network of physicians  through  which such care is provided  using the protocols
and guidelines  described above, and the computer resources described below, all
with a view to providing the highest quality, cost-effective cancer treatment.


At the  end  of  1994,  the  assets  and  liabilities  of  the  Clinical/Disease
Management Business were contributed to a newly-formed  wholly-owned subsidiary,
formerly   OnCare  Health  Inc.   (presently   named  Axion   HealthCare   Inc.)
("Controlled"), which conducts all of the foregoing activities.

The Distribution Business

In September 1990, Distributing began to distribute oncology pharmaceuticals and
related

                                                              September 11, 1996






supplies to office-based oncology practices (the "Distribution  Business").  The
Distribution  Business provides these practices with next-day delivery (compared
with days or weeks when the drugs are ordered  from the  manufacturer),  thereby
reducing inventory requirements and pharmaceutical expiration.

Distributing  directly  conducted both the  Clinical/Disease  Management and the
Distribution  Businesses until 1993. In July 1993,  Distributing  entered into a
series of agreements with Bristol-Myers Squibb Company ("Acquiring") to form the
Oncology   Therapeutics   Network  Joint  Venture,   L.P.,  a  Delaware  limited
partnership ("OTNJV").  Distributing formed a wholly-owned subsidiary,  Oncology
Therapeutics  Network  Corporation  ("OTNC"),  to act as the general  partner of
OTNJV. A wholly-owned subsidiary of Acquiring ("BMS Partner Sub") is the limited
partner.  Distributing  contributed the assets of its  Distribution  Business to
OTNC,  which,  in  turn,   contributed  those  assets  to  OTNJV.  In  addition,
Distributing  agreed  to  provide  all  administrative,  operational,  and other
services  necessary to support the joint venture,  subject to reimbursement  for
its costs by OTNJV.  Acquiring  appointed OTNJV as its exclusive sales agent for
Acquiring's oncology products for office-based practices.

In addition to the  Clinical/Disease  Management  and  Distribution  Businesses,
Distributing   conducts  an  Information   Management  Business  and  previously
conducted a Physicians Practice Management Business.

The Information Management Business

The Information  Management  Business,  which provides inventory and information
management  systems to oncology  practices,  is  conducted  through  OPUS Health
Systems,  Inc. formerly OnCare Systems Inc. ("OPUS"), a wholly-owned  subsidiary
of Distributing.  OPUS provides oncologists with state-of-the-art  technology in
inventory  management  and drug  utilization.  The  information  provided by the
Information  Management  Business allows oncologists to use the most appropriate
pharmaceuticals  (including  generics),  and  then  only  when  needed,  thereby
reducing inventory carrying costs.

Included in OPUS' Information  Management  Business is the OPUS Station activity
("OPUS  Station").  OPUS Station is an automated  drug  dispensing and inventory
tracking  activity,  specifically  tailored for use in the  outpatient  setting.
Located in the doctor's office, the OPUS

                                                              September 11, 1996






Station equipment links the local oncology practice with OTNJV.

OPUS also owns and operates the OPUS Matrix, a Windows-based  application,  that
generates  recommended treatment procedures from patient diagnoses and treatment
regimens.  As part of the disease  management  activity,  OPUS  Matrix  provides
office-based  oncology  practices with access to a central  database  containing
drug and treatment information.

The Physician Practice Business

OnCare Inc., previously a more-than-80-percent-owned subsidiary of Distributing,
is an  oncology-specific  physician practice management company,  which acquires
and manages local oncology practices (the "Physician  Practice  Business").  The
oncologists  who  were the  former  owners  of the  acquired  practices  work as
professional  service  providers to the company.  OnCare Inc.'s  providers  (who
employ the OnCare  treatment  guidelines in their  practice) are  represented to
health  plans as part of a select  managed  cancer care  network  that can offer
documented proof of  high-quality,  cost-effective  care. All of  Distributing's
common stock of OnCare Inc. was distributed to its  shareholders on December 31,
1995.

As of June 30, 1996,  Distributing  had one class of common  stock,  and several
classes of  preferred  stock,  issued  and  outstanding.  Distributing  also has
outstanding  certain  warrants and  employee  options with respect to its common
stock.  The common  stock  consists of 15 million  authorized  shares,  of which
approximately  1.6 million are issued and outstanding.  Preferred stock consists
of 10 million authorized  shares, of which  approximately 6.7 million are issued
and  outstanding.  The preferred stock is divided into Classes A - F; each class
is  convertible  into common stock.  No dividends are in arrears on any class of
preferred  stock.  Distributing  also has  outstanding  certain  employee  stock
options.

Distributing  uses the  accrual  method of  accounting  for  Federal  income tax
purposes and files its consolidated Federal income tax return on a calendar year
basis.


                                BUSINESS PURPOSE

The Acquisition is being  undertaken to secure a number of strategic  objectives
for Distributing

                                                              September 11, 1996






and  Acquiring,  including  (a)  elimination  of a  conflict  perceived  by  the
customers  of  the   Distribution   Business   between  that  business  and  the
clinical/disease   management  and  physician  practice   activities;   (b)  the
opportunity  to  increase  sales to  office-based  oncology  practices;  and (c)
allowing Acquiring to expand the quality of services provided to such practices.

Distributing   must  separate  the  Distribution   Business  from  the  rest  of
Distributing's activities in order to permit the Acquisition to occur. Acquiring
has stated that it has no interest in  acquiring  from  Distributing  any assets
other  than (i) 100  percent  of OTNC's  interest  in  OTNJV,  and (ii) the OPUS
Station   activities   (collectively   referred  to  as  the  "Wanted  Assets").
Accordingly,  as a condition to the  acquisition  of the stock of  Distributing,
Acquiring will require that Distributing divest all assets and liabilities other
than  the  Wanted  Assets  (and  related   liabilities)   prior  to  Acquiring's
acquisition of that stock. Further, separation of the Distribution Business from
its other  activities  is integral to  Distributing's  decision to undertake the
Acquisition.


                              PROPOSED TRANSACTION

The following transactions have been proposed for the business reasons described
above.

      1.   OTNJV will distribute to OTNC, cash representing a preference payment
           to which OTNC is entitled for periods ending June 30, 1996. OTNC will
           distribute that cash to Distributing.

      2.   OPUS will  transfer to a newly  created  corporation,  OPUS Sub,  the
           assets related to the OPUS Matrix activity.  OPUS Sub will assume all
           related liabilities.

      3.   OPUS will distribute the stock of OPUS Sub to Distributing.

      4.   Distributing  will contribute to Controlled all assets other than the
           Wanted  Assets.  Controlled  will assume all  liabilities  other than
           those  related to the Wanted Assets and those  previously  assumed by
           OPUS Sub.

      5.   Previously  nonvested  Distributing  options will become vested.  All
           options  will be exercised or  cancelled.  Distributing  will provide
           loans to facilitate exercise.

      6.   Controlled will be recapitalized through the exchange by Distributing
           of all of its  shares  of  Controlled  common  stock  for a number of
           shares of Controlled preferred stock equal to the number of shares of
           Distributing stock outstanding.

      7.   Distributing  will  distribute  all of the stock of Controlled to its
           shareholders on a pro rata basis.  (In order for the  distribution to
           be pro rata,  and to put the  Distributing  shareholders  in the same
           position  as if  Step  8  below  had  already  occurred,  holders  of
           Distributing  preferred  stock will waive  dividend  preferences  (if
           any)).

      8.   All of  Distributing's  preferred stock will be converted into common
           stock by vote of the preferred shareholders.

      9.   Acquiring  will cause a newly formed  wholly-owned  subsidiary,  OTNC
           Acquisition  Sub Inc.,  to merge into  Distributing.  In the  merger,
           Distributing's shareholders will receive solely stock of Acquiring in
           exchange for their  Distributing  stock. Cash will be paid in lieu of
           fractional shares.


                            MEMORANDUM OF AUTHORITIES

THE DISTRIBUTION OF CONTROLLED STOCK

Section  368(a)(1)(D)  of the  Internal  Revenue  Code of 1986,  as amended (the
"Code")  provides  in  part  that a  reorganization  includes  a  transfer  by a
corporation of part of its assets to another  corporation if,  immediately after
the transfer,  the  shareholders  of the transferor are in "control" (as defined
below) of the transferee,  and, pursuant to the plan, stock or securities of the
transferee are distributed in a transaction which qualifies under Section 355 of
the Code.

Board of Directors                                                        Page 8
                                                              September 11, 1996






Section 355 provides for the tax free  distribution of the stock of a controlled
subsidiary. In general, to meet the requirements of Section 355 --

(i)   Immediately  before the  distribution,  the distributing  corporation must
      "control" the  corporation  whose shares are being  distributed.  The term
      "control" is defined by Section  368(c) to mean stock  possessing at least
      80 percent of the total  combined  voting power and at least 80 percent of
      the  total  number  of shares  of all  other  classes  of  stock.  Section
      355(a)(1)(A);

(ii)  Immediately after the  distribution,  both the distributing and controlled
      corporations must be engaged in the active conduct of a trade or business.
      Section  355(a)(1)(C)  and (b). This active conduct of a trade or business
      requirement  is  satisfied  only if the  trade or  business  was  actively
      conducted   throughout  the  five-year   period  ending  on  the  date  of
      distribution,  and that business (or control of a  corporation  conducting
      that  business) was not acquired  within that period in a  transaction  in
      which gain or loss was recognized. Section 355(b)(2);

(iii) The  distributing  corporation  must  distribute  all  of  its  stock  and
      securities in the  controlled  corporation  or distribute  enough stock to
      constitute  control and establish to the satisfaction of the Treasury that
      the retention of stock in the controlled  corporation is not part of a tax
      avoidance plan. Section 355(a)(1)(D);

(iv)  The  transaction  must  not  be  used  principally  as a  device  for  the
      distribution of earnings and profits. Section 355(a)(1)(B);

(v)   There must be a  corporate  business  purpose  for the  transaction  and a
      continuity  of  interest.  Section  1.355-2(b)  and (c) of the  Income Tax
      Regulations (the "Regulations"); and

(vi)  The  transaction  must not  constitute a  "disqualified  distribution"  as
      defined in Section 355(d)(2) of the Code.


Control Immediately Before the Distribution

With regard to the Section 355 requirements  above, the test described in (i) is
satisfied  because  Distributing will own 100 percent of the stock of Controlled
immediately before the distribution.

Active Conduct of a Trade or Business

The  active  trade  or  business  requirement  of  Section  355(b)  has  several
components:  (i) the distributing and controlled corporations must be engaged in
the active conduct of a trade or business  immediately  after the  distribution;
(ii) the business(es) must have been actively conducted for the five-year period
before the distribution;  and (iii) neither the active business nor the stock of
the  controlled  corporation  may have been  acquired  in a taxable  transaction
during the five-year period preceding the distribution.  Sections  355(b)(1) and
(2).

The five-year  active  business  requirement is satisfied if the businesses have
been actively conducted by the distributing or controlled  corporations for five
years before the distribution.  Corporations are considered  actively engaged in
the  conduct  of a trade  or  business  if they  carry  on a  specific  group of
activities,  generally  including the  collection of income,  for the purpose of
earning a profit and the payment of expenses.  Section  1.355-3(b)(2)(ii) of the
Regulations.  A corporation is engaged in the active conduct of a trade business
if it is directly so engaged, or if "substantially all" of its assets consist of
stock of one or more corporations which are so engaged. Section 355(b)(2)(A).  A
corporation will meet this  "substantially all" requirement if 90 percent of the
fair  market  value  of  its  gross  assets  consists  of  stock  of  qualifying
corporations. Rev. Proc. 77-37, 1977-2 C.B. 568.

Generally,  a trade or business is  considered  to be actively  conducted if the
corporation  itself performs  active and substantial  management and operational
functions.  Although  activities  performed  on  behalf  of the  corporation  by
independent  contractors  and other  parties  outside  the  corporation  are not
considered as performed by the corporation,  the active conduct  requirement may
be  satisfied  even though some  activities  are  performed  by others.  Section
1.355-3(b)(2)(iii) of the Regulations.

Distributing  has  been  directly  engaged  in the  Clinical/Disease  Management
Business  from 1987 to 1994,  and  indirectly  engaged  in the  Clinical/Disease
Management Business through its wholly-owned  subsidiary Controlled from 1995 to
the present.  The activities of Controlled  that relate to the  Clinical/Disease
Management  Business  include the full process of earning  income or profit,  as
described in Section 1.355-3(b)(2)(ii) of the Regulations.

In this regard, we note that the disease  management  activity began in 1993. It
is unclear

whether this activity is a part of a single business,  or is a separate business
activity. Section 1.355-3(b)(3)(ii) of the Regulations provides that:

        "[I]f a  corporation  engaged  in the  active  conduct  of one  trade or
        business during that five-year period purchased,  created,  or otherwise
        acquired  another  trade or business in the same line of business,  then
        the  acquisition  of that other  business  is  ordinarily  treated as an
        expansion  of the original  business,  all of which is treated as having
        been  actively  conducted  during  that  five-year  period,  unless that
        purchase,  creation,  or other  acquisition  effects  a change of such a
        character  as  to  constitute  the  acquisition  of a new  or  different
        business."

As explained supra, in light of the fact that the disease management  activities
evolved out of, and use the information  developed by, the  corporation's  other
cancer focused healthcare activities, an argument can be made that these are all
part of single  business  activity.  Even if,  however,  the disease  management
activity  is viewed  to be a  separate  business,  Controlled  will  nonetheless
satisfy the 5-year active business test by virtue of its remaining activities.

In addition,  the proposed transactions  contemplate that Controlled will have a
substantial  amount of cash and similar  assets.  Assuming  arguendo  that these
assets are not viewed as active  business assets (see below),  nonetheless,  the
Internal  Revenue  Service (the  "Service") has held that a corporation may meet
the  active  business  test  even  though a small  percentage  of its  assets is
directly utilized in the active business activity.  See Rev. Rul. 73-44,  1973-1
C.B. 182; GCM 34238 (where the active business assets amount to 5 percent of the
total  assets).(1)  See  also,  TAM  8308007  (October  29, 1982).  Instead,  as
described more fully below,  the  existence of cash has been  analyzed under the
"device" rules.

In this regard,  it should be noted that, on August 8, 1996,  the Service issued
Rev. Proc.  96-43,  1996-35 I.R.B. 6, amplifying Rev. Proc. 96-3, 1996-1 IRB 82.
Rev. Proc. 96-43 provides that

(1) Pursuant  to  Section  6110(j)(3)  of  the  Code,  private  letter  rulings,
technical  advice  memorandums,  and  GCMs are not  cited as  precedent,  but to
illustrate a consistent position by the Service.

the Service will  ordinarily  not issue an advance  ruling  regarding  whether a
distribution  qualifies  under  Section 355 when the gross value of the trade or
business relied on to satisfy the active business  requirement is less than five
percent of the gross  value of all of the assets of the  corporation.  We do not
believe that the issuance of Rev. Proc. 96-43 changes the conclusions  expressed
herein.

Distributing has been directly engaged in the Distribution Business from 1990 to
1993,  and  indirectly  engaged in the  Distribution  Business  from 1993 to the
present  through  its  wholly-owned  subsidiary  OTNC  (which  owns a 50 percent
general partnership interest in OTNJV). The conduct of the Distribution Business
includes the full process of earning  income or profit,  as described in Section
1.355-3(b)(2)(ii) of the Regulations.

We  believe  that the  formation  of OTNJV and the  transfer  of assets to it in
1993 does not  cause  the   Distribution   Business   previously   conducted  by
Distributing to fail to satisfy the 5-year active business test. In this regard,
we note  that OTNC  actively  manages  the  operations  of  OTNJV.  Accordingly,
applicable  authorities  indicate  that  it is  still  actively  engaged  in the
Distribution Business begun by Distributing.

In Rev. Rul. 79-394, 1979-2 C.B. 141, amplified by Rev. Rul. 80-181, 1980-2 C.B.
121, the Service concluded that operational  activities  relating to corporation
X, that were conducted by another member of the affiliated  group of which X was
a member,  could be taken together with the management  activities  conducted by
the officers of X to satisfy the active trade or business requirement of Section
355.  Similarly,  in Rev. Rul.  92-17,  1992-1 C.B.  142, a limited  partnership
("LP")  owned  certain  real estate that it  operated  for more than 5 years.  D
corporation  had been a 20 percent  general partner in LP for more than 5 years.
D's officers  performed  active and  substantial  management  functions  for the
business  conducted by LP,  including  supervising  LP's employees.  The Service
concluded  that  management   activities  conducted  by  D  in  support  of  the
operational  activities  conducted by LP satisfied  the active trade or business
requirements  of Section 355. See also, PLR 9510005  (December 5, 1994) in which
the Service  applied Rev. Rul. 92-17 and found that a corporation met the active
trade or  business  requirement  of Section 355 where that  corporation  was the
managing general partner of a partnership that conducted a business meeting that
requirement.  Furthermore,  we understand that the day-to-day  operations of the
Distribution Business changed very little (if at all) after the formation of the
partnership, and are now conducted largely by employees of OTNC.

Accordingly,  we believe that  Distributing  (through  OTNC) should be viewed as
continuing its Distribution Business.

Thus, for the foregoing reasons,  while not free from doubt, we believe that the
active trade or business requirement for both Distributing and Controlled should
be satisfied in this case.

Distribution of Control

The requirement in (iii) will be satisfied in the proposed  transaction  because
Distributing  will  distribute  100  percent of the stock of  Controlled  to its
shareholders in the distribution.

Device to Distribute Earnings and Profits

As  noted,  Section  355(a)(1)(B)  of the Code  and  Section  1.355-2(d)  of the
Regulations  provide  that  Section  355 does not  apply to a  transaction  used
principally as a device for the  distribution of the earnings and profits of the
distributing corporation,  the controlled corporation,  or both. The Regulations
provide that,  generally,  the  determination  of whether a transaction was used
principally  as a device  will be made from all of the facts and  circumstances,
including,  but not  limited  to, the  presence  or  absence of certain  factors
described therein. Section 1.355-2(d) of the Regulations.

Section  1.355-2(d)(2)(iii)  of the Regulations provides that a sale or exchange
of the stock of the  distributing  or  controlled  corporation  is evidence of a
device. Section  1.355-2(d)(2)(iii)(E)  further provides, however, that if stock
is exchanged for stock in pursuance of a plan of reorganization in which no gain
or loss (or an insubstantial amount of gain) is recognized,  the exchange is not
treated as evidence of device, and the device rules will be applied by reference
to the  stock  received.  In the  present  case,  the  exchange  of the stock of
Distributing  after the  spin-off  will be effected  pursuant  to a  transaction
qualifying as a tax-free reorganization described in Section 368(a)(1)(B) of the
Code.  Accordingly,  such  exchange  will not  result in the  transaction  being
considered  to have been used  principally  as a  device.  Further,  it has been
represented that certain shareholders of Distributing have no plan or intention,
and the management of Distributing  knows of no plan or intention on the part of
the remaining Distributing shareholders, to sell or exchange stock of Controlled
or Acquiring after the Acquisition.

                                                              September 11, 1996







In general,  Section  1.355-2(d)(2)(iv)(B)  of the Regulations provides that the
existence of assets not used in a trade or business  (including  cash and liquid
assets not related to the reasonable needs of the business) is evidence that the
transaction  is being used  principally  as a device to distribute  earnings and
profits.   The  strength  of  this  evidence   depends  on  all  the  facts  and
circumstances,  including the ratio for each  corporation of the value of assets
not used in a trade or business  to the value of assets that  satisfy the active
trade or business  requirement of Section 355. Section  1.355-2(d)(3)(ii) of the
Regulations  provides that the existence of a corporate business purpose for the
transfer or retention of assets not used in a trade or business can outweigh the
evidence of device presented by such transfer or retention.

In the  present  case,  cash and other  liquid  assets  will be  transferred  by
Distributing   to  Controlled  as  part  of  the   transaction.   Management  of
Distributing  has indicated that the disease  management  activity of Controlled
(which, as noted, evolved from the clinical operations) will require substantial
funds beyond expected operating profits to maintain and expand its data base and
to market its services throughout the oncology community.  We further understand
that,  because these  activities are in their initial  stages,  it would be very
difficult for  Controlled  to obtain  lending from outside  sources.  Similarly,
management of  Distributing  and Controlled have  represented  that the cash and
other  liquid  assets will only be used in the business  activities  retained by
Controlled or to satisfy  obligations under agreements  relating to the Proposed
Transaction.  Further,  we  understand  that  Acquiring and  Distributing  never
considered that these assets would be retained in the  Distribution  Business or
otherwise included in the Acquisition.  Therefore,  arguably, the cash and other
liquid assets are related to the reasonable needs of Controlled's  business;  in
any event, there is a business purpose for the transfer.

The  Service  has ruled that a  contribution  to a  controlled  corporation,  in
anticipation of a spin-off,  made to allow the controlled  corporation to expand
its business,  is not indicative that the  transaction is used  principally as a
device to distribute earnings and profits.  In Rev. Rul. 83-114, 1983-2 C.B. 66,
immediately  prior  to  the  spin-off,  the  distributing  corporation  canceled
indebtedness  owed by a controlled  corporation in order to enable the latter to
expand  its  business  with  operating  proceeds  and  investment  capital.  The
cancellation  resulted in more  than a  100-percent  increase in the  controlled
corporation's  net worth.  Rev.  Rul.  83-114  concluded  that,  in light of the
business purpose for the contribution, the distribution was not used principally
as a device to distribute earnings and profits.

                                                              September 11, 1996






In  addition,  the  Service  has held that a  transfer  of cash to a  controlled
corporation  made to  equalize  values in a  split-off  transaction  will not be
considered  as evidence  that the  transaction  is being used  principally  as a
device for the  distribution  of earnings and  profits.  See Rev.  Rul.  64-102,
1964-1  C.B.  136  (capital  contribution  more  than  doubled  the value of the
controlled   corporation);   Rev.  Rul.   71-383,   1971-2  C.B.  180;   Section
1.355-2(d)(3)(iv)(B) of the Regulations. Compare Rev. Rul. 86-4, 1986-1 C.B. 174
(transfer of investment  assets by  distributing  to the controlled  corporation
immediately  prior to a pro-rata  spin-off was a factor to be considered,  along
with other factors,  in determining  whether the transaction was a device);  cf.
Rev. Rul. 59-400, 1959-2 C.B. 114, (shift in earnings from a hotel business to a
rental real estate business  approximately one year prior to a pro rata spin-off
resulted in nonqualification  under Section 355 in light of the fact that rental
real estate was involved).

Accordingly, based on the facts and circumstances,  cash and other liquid assets
can be contributed to a controlled corporation in anticipation of a distribution
without the  transaction  being  considered to have been used  principally  as a
device to distribute  earnings and profits.  The instant  transaction appears to
present such a case. Thus, in this case,  there is an important  business reason
for the  distribution  of the  stock of  Controlled,  i.e.,  to  facilitate  the
acquisition  by  Acquiring.  Further,  as stated  above,  there is an  important
business reason for the contribution of cash and similar  assets--i.e.,  to fund
the continued  development and expansion of the disease  management  activities.
Moreover,  these assets are not to be included in the Acquisition.  Accordingly,
while not free  from  doubt,  we  believe  that the  transaction  should  not be
considered to have been used  principally  as a device for the  distribution  of
earnings and profits.

Business Purpose

Section  1.355-2(b)  of the  Regulations  provides that Section 355 applies to a
transaction  only  if it is  carried  out for  one or  more  corporate  business
purposes. A transaction is carried out for a corporate business purpose if it is
motivated,  in whole or  substantial  part,  by one or more  corporate  business
purposes. A corporate business purpose is a real and substantial non-Federal tax
purpose germane to the business of the distributing corporation,  the controlled
corporation, or the affiliated group (as defined in Section 1.355-3(b)(4)(iv) of
the Regulations) to which the distributing corporation belongs.

                                                              September 11, 1996






The business  purpose test  described in (vi) above should be satisfied  because
the  business   purpose  for  the   transaction  is  to  facilitate  a  tax-free
reorganization.  In order to complete  the  Acquisition  under the facts of this
case, Acquiring is requiring  Distributing to divest the assets described above.
The Service has long and  consistently  recognized that a spin-off made in order
to permit a tax-free  reorganization  involving the distributing  corporation is
supported by a business  purpose.  See Rev. Rul.  68-603,  1968-2 C.B. 148, Rev.
Rul.  70-434,  1970-2 C.B. 83, and Rev.  Rul.  78-251,  1978-1 C.B. 89. See also
Commissioner v. Morris Trust, 367 F. 2d 794 (4th Cir. 1966).

There  are  no  other  tax-free  alternatives  to  accomplishing  this  business
objective. Thus, Acquiring cannot simply acquire the stock of OTNC directly from
Distributing,   as  such  an   acquisition   would   subject   Distributing   to
characterization  as an  "investment  company" as that term is defined under the
Investment Company Act of 1940, 15 U.S.C. ss. 80a-1 et seq. (the "1940 Act"). If
Distributing  were an  investment  company it would be required to register with
the Securities and Exchange  Commission (the "SEC"), and would become subject to
the 1940 Act's pervasive regulatory framework. Failure to register would subject
Distributing  and its  management  to  administrative  and  judicial  penalties,
including the possible voiding of any contracts entered into by the company and,
possibly,  criminal conviction of its management.  Once a company registers with
the SEC as an  investment  company,  the  company and its  directors,  officers,
substantial shareholders and other related persons are subject to a broad set of
regulatory  restrictions  administered  by the  SEC  over a  great  many  areas,
including the  composition  of the board of directors,  incentive  compensation,
issuances of stock,  capital structure,  asset composition and transactions with
affiliates.

In addition,  Distributing's  management believes that if it held a large amount
of its assets in the form of Acquiring stock,  Controlled's  disease  management
activity would be severely  adversely  affected.  Thus, one of the objectives of
this  activity  is to provide the most  cost-effective  care,  including  use of
pharmaceuticals.  Further, Controlled's relationship with the oncology community
(including  payers)  is based  upon this cost  containment  premise.  Management
believes  that  Controlled's  credibility,   and  consequently  its  ability  to
function,  would be seriously  undermined if its 100 percent  parent held as the
bulk of its assets an  interest  in a large  pharmaceutical  company  devoted to
maximizing profits on pharmaceutical sales. It has been a long-standing position
of  the  Service  that a  customer's  reluctance  to  purchase  products  from a
corporation (or one of its group members) because of other business  activity of
the group is a

valid  business  purpose  under Section 355 of the Code.  See Rev. Rul.  56-450,
1956-2 C.B. 201; Rev. Rul. 59-197, 1959-1 C.B. 77; PLRs 9539006 (June 27, 1995);
9524009  (March 15, 1995);  9438026 (June 28, 1994);  and 9331062  (February 17,
1993).

Continuity of Interest

Similarly, the continuity of interest requirement for a Section 355 distribution
will be satisfied  because 100 percent of the stock of Controlled  will be owned
by the  shareholders  of  Distributing.  After  the  Acquisition,  the  historic
shareholders  of  Distributing  will continue  their interest in the business of
Distributing through their stock ownership of Acquiring.  See, Rev. Rul. 68-603,
1968-2 C.B. 148, and Commissioner v. Morris Trust, 367 F.2d 794 (4th Cir. 1966).

Disqualified Distribution

Section  355 (d) of the  Code  provides  that,  in the  case of a  "disqualified
distribution,"  the  distributing  corporation  will recognize the gain (if any)
realized  on the  distribution  of the stock of the  controlled  corporation.  A
"disqualified  distribution" is defined as any distribution otherwise qualifying
under  Section 355 if,  immediately  after the  distribution,  any person  holds
"disqualified  stock"  in  the  distributing  or  controlled  corporation  which
constitutes   a   50-percent   or  greater   interest  in  either   corporation.
"Disqualified  stock"  is  defined  in  Section  355(d)(3)  as any  stock of the
distributing corporation acquired by purchase during the 5-year period ending on
the date of the distribution, and any stock of the controlled corporation either
acquired by purchase  during this 5-year period,  or  attributable  to purchased
distributing stock.

In the present case, no person has acquired a 50-percent or greater  interest in
the stock of Distributing  or Controlled  within the 5-year period ending on the
date of the distribution. Therefore, Section 355(d) will not apply to cause gain
recognition.

THE ACQUISITION OF DISTRIBUTING'S STOCK BY ACQUIRING.

Section 368(a)(1)(B) of the Code provides that the term "reorganization" (a Type
B  Reorganization)  includes the  acquisition  by one  corporation,  in exchange
solely for all or part of its voting stock, of stock of another  corporation if,
immediately after the acquisition, the

                                                              September 11, 1996






acquiring  corporation  has control of such other  corporation.  Section  368(c)
provides that, for this purpose, the term "control" means the ownership of stock
possessing at least 80 percent of the total combined voting power of all classes
of stock  entitled to vote and at least 80 percent of the total number of shares
of all other classes of stock of the corporation.

The control  requirement will be met in this case, since, after the Acquisition,
Acquiring will own all of the stock of Distributing.  Similarly, the "solely for
voting stock"  requirement  will be satisfied,  as we understand  that Acquiring
will acquire that  Distributing  stock solely for its own voting stock. The fact
that the transaction  will be  accomplished  through a merger of a newly-created
subsidiary into Distributing does not prevent the transaction from qualifying as
a Type B  Reorganization.  See Rev. Rul. 67-448,  1967-2 C.B. 144. The fact that
some  of the  Acquiring  stock  will  be  placed  in  escrow  will  not  prevent
satisfaction of the applicable requirements.  Rev. Proc. 77-37, 1977-2 C.B. 568,
as amplified by Rev. Proc. 84-42, 1984-1 C.B. 521.

Section  1.368-1(b)  of  the  Regulations   imposes  the  following   additional
requirements  which must be met for a transaction to qualify as a reorganization
within the meaning of Section 368: (i) "continuity of interest" must be present,
(ii)  "continuity of business  enterprise"  must exist, and (iii) an appropriate
business purpose must be present.

Rev.  Proc.  77-37,  1977-2 C.B. 568 provides that the  "continuity of interest"
requirement is satisfied if there is continuing interest through stock ownership
in the  acquiring  corporation  on the part of the  former  shareholders  of the
acquired  corporation  which is equal in value,  as of the effective date of the
reorganization,  to at least 50 percent of all of the formerly outstanding stock
of the  acquired  corporation  as of that date.  Sales,  redemptions,  and other
dispositions  of stock  occurring  prior or subsequent to the exchange which are
part of the plan of  reorganization  will be considered in  determining  whether
there is a 50 percent  continuing  interest  through  stock  ownership as of the
effective date of the reorganization.  In the proposed transaction, based on the
representations  received,  former shareholders of Distributing will receive and
retain  stock  of  Acquiring  with a  value  (as of the  effective  date  of the
reorganization)  equal to 100 percent of the value of all  formerly  outstanding
stock of Distributing.  Therefore,  the continuity of interest guideline of Rev.
Proc. 77-37 will be met.

Section  1.368-1(b)  of the  Regulations  provides that a continuity of business
enterprise (as

Board of Directors                                                       Page 19
                                                              September 11, 1996






described  in  Section  1.368-1(d)  of  the  Regulations)  is a  requisite  to a
reorganization.  Section 1.368-1(d) of the Regulations  provides that continuity
of business enterprise  requires that the acquiring  corporation either continue
the acquired corporation's historic business or use a significant portion of the
acquired  corporation's  historic assets in a business. The proposed transaction
will meet the  continuity  of  business  enterprise  requirement  as it has been
represented  that, after the transaction,  Distributing  will be engaged through
OTNC in its historic  Distribution  Business.  See Rev. Rul. 85-198, 1985-2 C.B.
121.  The fact that all  partnership  assets  and  liabilities  will now be held
directly by OTNC should not change this result.

Section  1.368-2(g) of the Regulations  provides that a  reorganization  must be
undertaken  for  reasons  germane  to  the  continuance  of  the  business  of a
corporation a party to the  reorganization.  As described above, the Acquisition
will  be  undertaken  for  substantial  business  reasons.  Thus,  the  proposed
transaction will be motivated by a valid business purpose in accordance with the
Regulations.

Section  368(b) of the Code  defines the term "a party to a  reorganization"  to
include a corporation resulting from a reorganization, and both corporations, in
the case of a  reorganization  resulting from the acquisition by one corporation
of stock or properties of another.

Section 354(a)(1)  provides that no gain or loss shall be recognized if stock or
securities in a corporation a party to a reorganization are, in pursuance of the
plan of  reorganization,  exchanged  solely  for  stock  or  securities  in such
corporation or in another corporation a party to the reorganization.


                         FEDERAL INCOME TAX CONSEQUENCES

Based solely upon the facts and information  presented in the Documents,  and on
the  information  set forth in this opinion  letter and subject to the "SCOPE OF
OPINION,"  described below, it is our opinion that the following  Federal income
tax consequences should result from the Proposed Transaction described above:

(1)     The transfer by  Distributing to Controlled of the assets other than the
        Wanted Assets

        solely in constructive  exchange for additional  stock of Controlled and
        the assumption of certain liabilities,  as described above,  followed by
        the distribution of the Controlled stock pro rata to the shareholders of
        Distributing  should qualify as a  reorganization  within the meaning of
        Section  368(a)(1)(D) of the Code.  Distributing  and Controlled  should
        each be "a party to a  reorganization"  within  the  meaning  of Section
        368(b).

(2)     No gain or loss will be recognized to Distributing  upon the transfer of
        the  assets,  subject to  liabilities,  to  Controlled  in  constructive
        exchange for Controlled stock (Sections 351(a), 361(a) and 357(a)).

(3)     No gain or loss will be  recognized  by  Controlled  upon the receipt of
        assets in constructive exchange for Controlled stock (Section 1032(a)).

(4)     The basis of the assets  received by Controlled  will be the same as the
        basis of such assets in the hands of Distributing  immediately  prior to
        the Proposed Transaction (Section 362(b)).

(5)     The holding  period of the  Distributing  assets  received by Controlled
        will  include  the  period   during  which  such  assets  were  held  by
        Distributing (Section 1223(2)).

(6)     No gain or loss  should  be  recognized  to  (and no  amount  should  be
        included in the income of) the  shareholders  of  Distributing  upon the
        receipt of the Controlled stock (Section 355(a)(1)).

(7)     No  gain  or  loss  should  be  recognized  to  Distributing   upon  the
        distribution  of the Controlled  stock pro rata to the  shareholders  of
        Distributing (Section 361(c)(1)).

(8)     The basis of the Controlled and  Distributing  stock in the hands of the
        shareholders  of  Distributing  should  be the same as the  basis of the
        Distributing stock held by the shareholders of Distributing  immediately
        before the  distribution,  allocated  in  proportion  to the fair market
        value  of  each  in  accordance  with  Section   1.358-2(a)(2)   of  the
        Regulations (Section 358(b)(1)).

(9)     As provided in Section 312(h) of the Code, proper allocation of earnings
        and profits

        between  Distributing  and Controlled  should be made in accordance with
        Section 1.312-10(a) of the Regulations.

(10)    Provided the Distributing  stock was held as a capital asset on the date
        of the  distribution of the Controlled  stock, the holding period of the
        Controlled  stock received by the  shareholders of  Distributing  should
        include the holding  period of the  Distributing  stock with  respect to
        which the distribution was made (Section 1223(1)).

(11)    The acquisition by Acquiring of all the stock of Distributing  solely in
        exchange for  Acquiring  stock,  as described  above,  will qualify as a
        reorganization under Section 368(a)(1)(B) of the Code.  Distributing and
        Acquiring will each be "a party to a reorganization"  within the meaning
        of Section 368(b).

(12)    No gain or loss will be recognized by the Distributing shareholders upon
        the receipt of Acquiring stock solely in exchange for Distributing stock
        (Section 354(a)(1)).

(13)    The basis of the Acquiring stock received by Distributing's shareholders
        in exchange for Distributing  stock will be the same as the basis of the
        Distributing stock surrendered in exchange therefor (Section 358(a)(1)).

(14)    The holding period of the Acquiring  stock received by the  Distributing
        shareholders  in the  Exchange  will  include the holding  period of the
        Distributing  stock  surrendered  in  exchange  therefor,  provided  the
        Distributing  stock  is held as a  capital  asset  in the  hands  of the
        Distributing shareholders on the date of the exchange (Section 1223(1)).


                                SCOPE OF OPINION

The scope of this opinion is expressly  limited to the Federal income tax issues
specifically  addressed  in (1) through  (14) in the section  entitled  "FEDERAL
INCOME TAX CONSEQUENCES" above. We have made no determination, nor expressed any
opinion  as to any  limitations,  including  those  which may be  imposed  under
Section 382, on the  availability  of net operating loss carryovers (or built-in
losses), if any, after the Proposed Transaction, the application (if any) of the
alternative minimum tax to the Proposed Transaction, or on any

consolidated  return,  employee  benefit,  or foreign  tax  (including,  without
limitation,  the  application of Section 367 of the Code) issues which may arise
as  a  result  of  the  Proposed  Transaction.   Similarly,   we  have  made  no
determination   nor  expressed  any  opinion   regarding  the   consequences  to
Distributing  shareholders entitled to special treatment under the Code (such as
insurance companies,  dealers in securities,  or tax exempt organizations) or to
Distributing  shareholders  who  acquired  their  shares of  Distributing  stock
pursuant to the exercise of employee stock options or otherwise in  compensatory
transactions. In addition, we have expressed no opinion on the conversion of the
Distributing  preferred into common stock,  on the exercise of the  Distributing
options,  the  recapitalization  of  Controlled,   the  transfer  of  assets  or
liabilities to  Distributing  or any of its direct or indirect  subsidiaries  in
anticipation  of,  or as  part  of,  the  Proposed  Transaction  (other  than as
described in (1) above), or on the effect of any arrangements  between Acquiring
or its  subsidiaries  and  Controlled  or  its  subsidiaries  subsequent  to the
Acquisition.  Furthermore,  our  opinion  has not  been  requested,  and none is
expressed,  with  respect to any  foreign,  state or local tax  consequences  to
Distributing, Controlled, or the shareholders of Distributing.

We note  that any  variation  or  differences  in the  facts or  representations
recited  herein,  for any reason,  might affect our  conclusions,  perhaps in an
adverse manner, and may make them inapplicable.  Further, our opinions are based
upon the analysis of the Code, the Regulations thereunder, current case law, and
published  rulings.  The foregoing are subject to change, and such change may be
retroactively  effective.  If so, our views, as set forth above, may be affected
and may not be relied upon.  We have  undertaken  no  obligation to update these
opinions for changes in facts or law  occurring  subsequent to the date thereof.
We do note  that on March  19,  1996,  the  Clinton  Administration  sent to the
Congress a proposal  (the  "Proposal")  to require gain  recognition  on certain
Section  355  distributions  when  at  least  50  percent  of the  stock  of the
distributing  or the controlled  corporation is not held at all times during the
four year  period  commencing  two years  before and ending two years  after the
distribution  by the  direct  and  indirect  shareholders  of  the  distributing
corporation.  If  the  Proposal  were  applicable  to the  instant  transaction,
Distributing  would be  required  to  recognize  gain (if any)  realized  on the
distribution of the Controlled stock since the shareholders of Distributing will
own less than 50  percent of the stock of  Acquiring.  The  Proposal  would not,
however, change the treatment of Distributing's  shareholders,  described above.
While the Proposal  stated that the provisions  would generally be effective for
distributions  after March 19, 1996, a statement by Senator Roth and Congressman
Archer issued on March 29, 1996, indicated that "it is intended that the

effective   date.  .  .  will  be  no  earlier  than  the  date  of  appropriate
Congressional action." We express no opinion regarding whether the Proposal will
or will not be applicable to the proposed transaction.

This letter is not intended to be, and should not be, distributed or relied upon
by  any   entities  or  persons   other  than   Distributing,   Controlled   and
Distributing's  shareholders.  In addition, except as expressly set forth above,
this letter  should not be quoted or otherwise  referred to in any  documents or
filed  with or  furnished  to any  agency  (other  than  with the  Service  upon
examination) without the express written consent of Ernst & Young LLP.

This letter is an opinion of our firm as to the  interpretation  of existing law
and, as such, is not binding on the Service or the courts.
