Item 2. Acquisition or Disposition of Assets

      On January 11, 1999, the Registrant acquired (the "Acquisition") from TFX
Equities Incorporated ("TFX") 100 shares of Common Stock, par value $1.00 per
share, of Endoscopy Specialists Incorporated ("ESI") (being all the issued and
outstanding ESI Common Stock); as well as 625 shares of SSI Surgical Services,
Inc. ("SSI") (being all the issued and outstanding shares of Common Stock of SSI
not already held by the Registrant), and 100 shares of Series A Non-Voting
Preferred Stock) par value $1.00 per share (being all the issued and outstanding
shares of Preferred Stock of SSI).

      In consideration for the shares of ESI and SSI acquired by the Registrant,
the Registrant issued to TFX 13,400,000 shares of Common Stock, par value $.01
per share, of the Registrant ("MSI Common Stock") and warrants to purchase (i)
1,250,000 shares of MSI Common Stock at $1.38 per share and (ii) 250,000 shares
of MSI Common Stock at $2.00 per share.

      The Registrant retained Needham & Company, Inc. ("Needham") to provide
financial advisory services with respect to the Acquisition. On November 18,
1998, Needham delivered its written opinion (the "Fairness Opinion") that as of
such date and based upon and subject to cer-
<PAGE>

tain assumptions and other matters described in its opinion, the consideration
to be received by the Registrant in the Acquisition is fair to the shareholders
of the Registrant (other than TFX) from a financial point of view.

      As previously set forth, the shares of stock were acquired from TFX. TFX
had previously acquired 687,500 shares of Series B Convertible Preferred Stock,
1,945,625 shares of Series C Convertible Preferred Stock and 150,000 shares of
Common Stock of the Registrant, or approximately 48% of the Registrant's voting
stock. Furthermore, three of the directors of the Registrant were employed by
TFX or affiliates.

      In an additional relationship between TFX and the Registrant, the
Registrant and TFX entered into a joint venture in May, 1997 to form SSI to
expand the Registrant's services throughout the United States. TFX received 
62 1/2% of the stock of SSI in consideration for cash, committed management and
funding working capital requirements. The Registrant received 37 1/2% of the
stock of SSI in consideration for certain technologies, processes and defined
territorial rights.

Endoscopy Specialists Incorporated

      ESI, headquartered in Orlando, Florida, was incorporated in 1993 to
provide endoscopic instrument sets to hospitals and other medical facilities on
a per procedure basis. In August 1995, ESI was acquired by TFX.

      ESI provides customers specified endoscopic instruments and specialty
products required to perform designated endoscopic surgical procedures. In
addition, ESI assigns highly trained service technicians to each customer
hospital. The ESI service technician is responsible for assisting with the
operating room set up prior to the start of the designated endoscopic case, and
remains on site to serve as a technical expert available to respond to questions
from the surgical staff regarding the proper use of the products and video
systems supplied by ESI. At the completion of the case, the ESI technician
decontaminates and reprocesses the ESI instruments and performs quality
assurance checks on the instruments to validate their readiness for the next
procedure. ESI manages all repairs, refurbishing, reprocessing and replacement
costs associated with the provided products.

      ESI offers services for general surgery, gynecology, urology, ENT,
orthopedics, plastic surgery, thoracic surgery and cardiovascular surgery. The
related ESI instrument sets can be basic, containing only instrumentation, or
increasingly complex, to include scopes, video equipment and other accessories.
By using high quality reusable instruments that are properly managed by trained
ESI technicians, ESI delivers higher quality products billed on a per procedure
basis, thus providing a basis for potentially reducing hospital costs.


                                       2

      ESI currently provides services to approximately 100 hospitals and surgery
centers throughout the United States. Maintaining its growth on a controlled
basis, ESI expects to continue to build its business through the strength of its
reputation.

SSI Surgical Services, Inc.

      SSI, headquartered in Orlando, Florida, was formed in 1997 as a joint
venture between TFX and the Registrant. SSI was established to provide general
and specialty instrument sets, basins and surgical gowns and towels to hospitals
and other facilities. In August 1998, SSI acquired Sterilization Management
Group ("SMG") which owned and managed five surgical instrument and linen
reprocessing facilities located in major metropolitan areas in the United
States.

      SSI offers a broad menu of services both on-site (at customer locations)
and off-site (at the five SSI facilities). These services include, facility
assessment, on-site department management and staffing, asset inventory
management systems, surgical instrument management, equipment and sterile
processing department redesign, sterile processing department
education/certification and off-site sterile reprocessing of surgical
instruments, gowns and towels. SSI currently provides on-site services to six
hospitals and surgery centers and off-site sterilization services to more than
100 customers. SSI's focus on education and management services, strategic
alliances with suppliers of sterilization equipment and asset management
systems, on staff instrument repair and refurbishment resources and its highly
trained team of professionals is expected to allow for continued growth and a
competitive point of difference.

                                  (Unaudited)

Description of Transaction

      Pursuant to an Acquisition Agreement, dated November 19, 1998, between the
Company and TFX, the Company will exchange 13,400,000 shares of Common Stock and
warrants to purchase an aggregate of 1,500,000 shares of Common Stock for 100
shares of Common Stock, par value $1.00 per share, of ESI and 625 shares of
Common Stock, par value $1.00 per share, and 100 shares of Series A Non-Voting
Preferred Stock, par value $1.00 per share, of SSI.

Method of Accounting

      The unaudited pro forma consolidated condensed financial statements of
operations for the year ended December 31, 1997 mid the nine months ended
September 30, 1998 arc based on the historical financial information of the
Company and combined ESI/SSI, adjusted to give effect, using the purchase method
of accounting, to the Acquisition and the pro forma effect of the acquisition of
SMG by SSI as of January 1, 1997. All material intercompany transactions have
been eliminated in the historical financial statements.

      The unaudited pro forma balance sheet has been prepared assuming that the
Acquisition occurred on September 30, 1998.

      The unaudited pro forma financial information does not purport to
represent what the Company's results of operations or financial position would
have been had the Acquisition or SSI's acquisition of SMG occurred as of January
1, 1997 or to project the Company's or combined ESI/SSI's results of operations
or financial position for a future period or date, nor does it give effect to
any matters other than those described in the notes thereto.

                             ACQUISITION AGREEMENT

      This Acquisition Agreement (the "Agreement") is made this 19th day of
November, 1998, between TFX EQUITIES INCORPORATED, a Delaware corporation
("TFX"), and MEDICAL STERILIZATION, INC., a New York corporation ("MSI").

                                   Background

      A. MSI is engaged in the business of providing off-site reprocessing and
sterilization of standard containerized reprocesable sterilized surgical
instrument sets as well as certain other items requiring sterilization for
healthcare providers such as hospitals, hospital networks and ambulatory
surgi-centers.

      B. Pursuant to Section 713(a)(l) of the New York Business Corporation Law,
following full and good faith disclosure of material facts of the interests of
the Interested Directors (as hereinafter defined) in this Agreement and the
transactions contemplated herein, the Board of Directors of MSI, including all
directors of MSI who are not Interested Directors (the "Independent Directors"),
has unanimously determined that the issuance by MSI of 13,400,000 shares of MSI
Common Stock (as hereinafter defined) and the MSI Warrants (as hereinafter
defined) to TFX in exchange for TFX's contribution to MSI of (i) all of the
outstanding capital stock of Endoscopy Specialists Incorporated, a Delaware
corporation ("ESI"), (ii) 625 shares of common stock of SSI Surgical Services,
Inc., a Delaware corporation ("SSI") and (iii) l00 shares of SSI Series A
Preferred Stock (as hereinafter defined), all on the terms and conditions set
forth herein, is fair and in the best interests of the shareholders of MSI other
than TFX (the "Public Shareholders") and has unanimously approved this Agreement
and the transactions contemplated herein, which approval was based in part on
the opinion of Needham & Company, Inc. (the "Independent Advisors"), independent
financial advisors to the Board of Directors of MSI, that, as of the date of
such opinion and based on the assumptions, qualifications and limitations
contained therein, the consideration to be received by MSI for the issuance of
the Issued MSI Stock (as hereinafter defined) and the MSI Warrants is fair to
the Public Shareholders from a financial point of view.

      C. At October 31, 1998, TFX owned 150,000 shares of MSI Common Stock,
687,500 shares of MSI Series B Convertible Preferred Stock and 1,945,625 shares
of MSI Series C Convertible Preferred Stock. Shares of MSI Series B Convertible
Preferred Stock and dividends accrued thereon are convertible into shares of MSI
Common Stock (as hereinafter defined). Shares of MSI Series C Convertible
Preferred Stock are convertible into shares of MSI Common Stock, The Board of
Directors of TFX deems it advisable and in the beat interest of TFX and the
stockholder of TFX for TFX, (i) immediately prior to the Closing (as hereinafter
defined), to convert all of the shares of (a) MSI Series B Convertible Preferred
Stock, and all dividends accrued thereon, and (b) MSI Series C Convertible
Preferred Stock into shares of MSI Common Stock (the "Conversion") and, (ii) as
part of the Closing, to exchange all of its shares of Common Stock of ESI, SSI
Common Stock and SSI Series A Preferred Stock for shares of MSI Common Stock and
the warrant to purchase 1,250,000 shares of MSI Common Stock in the form
attached as Exhibit A hereto (the "MSI $1.38 Warrant") and the warrant to
purchase 250,000 shares of MSI Common Stock in the form attached as Exhibit B
hereto (the "MSI $2.00 Warrant" and together with the MSI $1.38 Warrant, the
"MSI Warrants").

      D. In order to consummate both the Conversion and the Exchange (as
hereinafter defined), MSI will have to increase the number of authorized but
unissued shares of MSI Common Stock. Accordingly, the Board of Directors of MSI,
including all of the Independent Directors, has unanimously authorized an
amendment to the certificate of incorporation, as amended, of MSI in the form
attached as Exhibit C hereto (the "Amendment") to increase the number of shares
of MSI Common Stock authorized and has unanimously recommended that the
shareholders of MSI authorize the Amendment.

                                      Terms

      In consideration of the mutual covenants contained herein and intending to
be legally bound hereby, the parties hereto agree as follows;

                                    ARTICLE I

                                   DEFINITIONS

      For the purposes of this Agreement, the following words and phrases shall
have the following meanings:

            "Affiliate" of a Person means any Person controlling, controlled by,
or under common control with, such Person. For purposes of this definition,
"control" means the power to direct the management and policies of a Person,
whether through the ownership of voting securities, by agreement or otherwise.

            "Agreement" shall have the meaning set forth in the Introduction.

            "Amendment" shall have the meaning set forth in the Introduction.

            "Authority" shall have the meaning set forth in Section 3.8.

            "Best Efforts" is defined to require that the obligated party make a
diligent, reasonable and good faith effort to accomplish the applicable
objective. Such obligation, however, does not require any significant
expenditure of funds or the incurrence of any significant liability on the part
of the obligated party, nor the incurrence of any expense or liability which is
unreasonable in light of the related objective, nor does it require that the
obligated party act in a manner which would otherwise be contrary to prudent
business judgment or normal commercial practices in order to accomplish the
objective. The fact that the objective is not actually accomplished is no
indication that the obligated party did not in fact utilize its Best Efforts in
attempting to accomplish the objective.

            "Business" means MSI's provision of off-site reprocessing and
sterilization of standard containerized reprocessable sterilized surgical
instrument sets as well as certain other items requiring sterilization for
healthcare providers such as hospitals, hospital networks and ambulatory
surgi-centers.

statutory or civic holiday in the State of New York or any other day on which
the principal offices of either TFX or MSI are closed or become closed prior to
2:00 p.m. local time whether in accordance with established company policy or as
a result of unanticipated events including adverse weather conditions.

            "Claim Notice" shall have the meaning set forth in Section 10.3.

            "Claim Response" shall have the meaning act forth in Section 10.3.

            "Closing" shall have the meaning set forth in Section 2.2.

party claims, whether or not meritorious), costs and expenses whatsoever

(a) set forth on Schedule 8.4 or (b) material to the Business) shall have been
obtained (except for such consents and approvals (other than those set forth on
Schedule 8.4) that if not obtained would not in the aggregate have a material
adverse effect on the Business as a whole), and all waiting periods specified by
law the passing of which are necessary for the consummation of such transactions
shall have passed or been terminated.

8.5. Absence of Changes. There shall not have occurred or been threatened (i)

8.6. Fairness Opinion. Prior to the date on which the Proxy Statement is mailed

Closing Date, such opinion shall not have been withdrawn or modified in form or
substance in a manner unsatisfactory to MSI.

                          CERTAIN ADDITIONAL COVENANTS

9.1. Termination.

(a) When Agreement May Be Terminated. This Agreement may be terminated at any
time prior to Closing:

(i) by mutual consent of TFX and MSI;

(ii) by TFX if there has been a material breach by MSI of any of its
representations, warranties or covenants under this Agreement which breach is
not curable, or, if curable, MSI has not commenced actions to cure such breach
within 10 days of written notice thereof and cured such breach within 45 days of
such notice;

(iii) by MSI if there has been a material breach by TFX of any of its
representations, warranties or covenants under this Agreement which breach is

either TFX or MSI, as provided above, this Agreement shall forthwith terminate

respective officers or directors, except for liabilities arising from a breach
of this Agreement prior to such termination; provided, however, that under no
circumstances shall such liabilities include any consequential or incidental
damages; provided, further, that the obligations of the parties set forth in
Section 9.2 hereof shall survive such termination.

9.2. Costs, Expenses and Taxes. Each party to this Agreement will bear all the
fees, costs and expenses which are incurred by it in connection with the
transactions contemplated hereby.

                                    ARTICLE X

                                 INDEMNIFICATION

10.1. Indemnification By MSI. MSI hereby agrees to indemnify and hold harmless
TFX from and against any Damages arising out of or resulting from (i) the breach
or inaccuracy of any representation or warranty made by MSI in this Agreement;
or (ii) the breach by MSI of any covenant contained in this Agreement.

10.2. Indemnification by TFX. TFX hereby agrees to indemnify and hold harmless
MSI from and against any Damages arising out of or resulting from (i) the breach
or inaccuracy of any representation or warranty made by TFX in this Agreement;
(ii) the breach by TFX of any covenant contained in this Agreement or (iii)
material inaccuracy of information concerning ESI or SSI provided by TFX to MSI
that results in liability to MSI pursuant to Addendum A to the Letter Agreement,
dated September 28, 1998, between MSI and Needham & Company, Inc.

10.3. General Indemnification Procedures.

(a) In the event that any party incurs or suffers any Damages with respect to
which indemnification may be sought by such party pursuant to this Article X,
the party seeking indemnification (the "Indemnitee") must assert the claim by
giving written notice (a "Claim Notice") to the party from whom indemnification
is sought (the "Indemnitor"). The Claim Notice must state the nature, basis and
amount (if known) of the claim in reasonable detail based on the information
available to the Indemnitee and, if the Claim Notice is being given with respect
to a third party claim, it must be accompanied by a copy of any written notice
of the third party claimant. If the Claim Notice is being given by reason of any
third party claim,


                                       11
<PAGE>

it shall be given in a timely manner but in no event more than 30 days after the
filing or other written assertion of any such claim against the Indemnitee, but
the failure of the Indemnitee to give the Claim Notice within such time period
shall not relieve the Indemnitor of any liability for indemnification under this
Article X, except to the extent that the Indemnitor is prejudiced thereby. If
the amount of the claim is not known at the time the Claim Notice is given, the
Indemnitee shall also give notice of such amount to the Indemnitor at such time
as the amount of the claim is reasonably ascertainable. Each Indemnitor to whom
a Claim Notice is given shall respond to any Indemnitee that has given a Claim
Notice (a "Claim Response") within 30 days (the "Response Period") after the
date that the Claim Notice is received by Indemnitor. Any Claim Response shall
specify whether or not the Indemnitor given the Claim Response disputes the
claim described in the Claim Notice. If any Indemnitor fails to give a Claim
Response within the Response Period, such Indemnitor shall be deemed not to
dispute the claim described in the related Claim Notice, in whole or in part. If
any Indemnitor elects not to dispute a claim described in a Claim Notice,
whether by failing to give a timely Claim Response or otherwise, then such claim
shall be conclusively deemed to be an obligation of such Indemnitor. If any
Indemnitor shall be obligated to indemnify an Indemnitee hereunder, such
Indemnitor shall pay to such Indemnitee within 30 days after the last day of the
applicable Response Period (or at such later time as the amount is
ascertainable) the amount to which such Indemnitee shall be entitled. If there
shall be a dispute as to the amount or manner of indemnification under this
Agreement, the Indemnitor and the Indemnitee shall seek to resolve such dispute
through negotiations and, if such dispute is not resolved within 20 days, the
Indemnitee may pursue whatever legal remedies may be available for the recovery
of the Damages claimed from any Indemnitor. If any Indemnitor fails to pay all
or any part of any indemnification obligation on or before the later to occur of
(x) 30 days after the last day of the applicable Response Period, and (y) if the
Claim Notice relates to Damages that have not been liquidated as of the date of
the Claim Notice, the date on which all or any part of such Damages shall have
become liquidated and determined, then the Indemnitor shall also be obligated to
pay to the Indemnity interest on the unpaid amount for each day during which the
obligation remains unpaid at an annual rate of ten percent.

(b) The Indemnitee shall provide to the Indemnitor on request all information
and documentation reasonably necessary to support and verify any Damages that
the Indemnitee believes give rise to the claim for indemnification hereunder and
shall give the Indemnitor reasonable access to all books, records and personnel
in the possession or under the control of the Indemnitee that would have bearing
on such claim.

(c) Except as hereinafter provided, in the case of third party claims for which
indemnification is sought, the Indemnitor shall have the option: (x) to conduct
any proceedings or negotiations in connection therewith, (y) to take all other
steps to settle or defend any such claim (provided that the Indemnitor shall not
settle any such claim without the consent of the Indemnitee (which consent shall
not be unreasonably withheld, it being understood that it shall not be
unreasonable for the Indemnitee to withhold its consent from any settlement
which (1) commits the Indemnitee to take, or to forbear to take, any action, or
(2) does not provide for a complete release of the Indemnitee by such third
party)), and (z) to employ counsel to contest any such claim or liability in the
name of the Indemnitee or otherwise. In any event, the Indemnitee shall be
entitled to participate at its own expense and by its own counsel (a "Voluntary
Participation") in any proceedings relating to any third party claim. The
Indemnitor shall, within 45 days of receipt of the Claim Notice, notify the
Indemnitee of its intention to assume the defense of the claim (a "Defense
Notice"). Until the Indemnitee has received the Defense Notice, the Indemnitee
shall take reasonable stops to defend (but may not settle) the claim. If the
Indemnitor declines to assume the defense of any such claim or fails to give a
Defense Notice within 45 days prior receipt of the Claim Notice, the Indemnitee
shall defend against the claim but shall not settle such claim without the
consent of the Indemnitor (which consent shall not be unreasonably withheld).
The expenses of all proceedings, contests or lawsuits (other than those
incurred in a Voluntary Participation) with respect to claims as to which a
party is entitled to indemnification under this Article X shall represent
indemnifiable Damages under this Agreement. Regardless of which party shall
assume the defense of the claim, the parties shall cooperate fully with one
another in connection therewith. Notwithstanding the foregoing, the Indemnitor
shall not be entitled (except with the consent of the Indemnitee) to take any of
the actions referred to in clauses (x), (y) or (z) of the first sentence of this
subparagraph unless: (a) the third party claim involves principally monetary
damages; and (b) the Indemnitor shall have expressly agreed in writing that, as
between the Indemnitor and the Indemnitee, the Indemnitor shall be solely
obligated to satisfy and discharge such third party claim. Damages payable
hereunder shall be appropriately adjusted to reflect the receipt of insurance
proceeds, tax benefits and detriments and proceeds received with respect to
condemnation, expropriation or eminent domain proceedings.


                                       12
<PAGE>

(d) No action or claim for Damages pursuant to Sections 10.1 or 10.2 hereof
shall be brought or made after April 30, 2000, except that such time limitation
shall not apply to claims for misrepresentations or breaches of warranty
relating to Sections 3.10 and 4.9 which may be asserted until 60 days after the
running of the applicable statute of limitations with respect to such claims.

(e) Indemnification pursuant to this Article X shall be the sole and exclusive
remedy available to the parties hereto for any and all Damages.

                                   ARTICLE XI

                      To Purchase Shares of Common Stock of

                           MEDICAL STERILIZATION, INC.

            Medical Sterilization, Inc., a New York corporation (the "Company"),
hereby certifies that, for value received or assigned, TFX Equities
Incorporated, a Delaware corporation, ("TFX"), is entitled, subject to the terms
set forth below, to purchase from the Company at any time or from time to time
before 5:00 P.M., New York City time, on December 31, 2005, 1,250,000 fully paid
and nonassessable shares of Common Stock, $.01 par value, of the Company, at a
purchase price per share of $1.38 (the "Purchase Price"). The number and
character of such shares of Common Stock are subject to adjustment as provided
herein.

            This Warrant is the MSI Warrant (the "Warrant") evidencing the right
to purchase shares of Common Stock of the Company, issued pursuant to a certain
Acquisition Agreement (the "Agreement"), dated as of November 19, 1998, between
the Company and TFX, a copy of which is on file at the principal office of the
Company.

            As used herein the following terms, unless the context otherwise
requires, have the following respective meanings:

            (a) The term "Company" shall include Medical Sterilization, Inc. and
any corporation which shall succeed or assume the obligations of the Company
hereunder.

            (b) The term "Common Stock" includes (a) the Company's Common Stock,
$.01 par value per share, as authorized on the date of the Agreement, (b) any
other capital stock of any class or classes (however designated) of the Company,
authorized on or after such date, the holders of which shall have the right,

current dividends and liquidating dividends after the payment of dividends and
distributions on any shares entitled to preference, and the holders of which
shall ordinarily, in the absence of contingencies, be entitled to vote for the
election of a majority of directors of the Company (even though the right so to
vote has been suspended by the happening of such a
<PAGE>

contingency) and (c) any other securities into which or for which any of the
securities described in (a) or (b) may be converted or exchanged pursuant to a
plan of recapitalization, reorganization, merger, sale of assets or otherwise.

            (c) The term "Other Securities" refers to any stock (other than
Common Stock) and other securities of the Company or any other person (corporate
or otherwise) which the holder of the Warrant at any time shall be entitled to
receive, or shall have received, on the exercise of the Warrant, in lieu of or
in addition to Common Stock, or which at any time shall be issuable or shall
have been issued in exchange for or in replacement of Common Stock or Other
Securities.

      1. Exercise of Warrant.

      1.1. Full Exercise. This Warrant may be exercised in full by the holder
hereof by surrender of this Warrant, with the form of subscription at the end
hereof duly executed by such holder, to the Company at its principal office,
accompanied by payment in cash or by certified or official bank check payable to
the order of the Company, in the amount obtained by multiplying the number of
shares of Common Stock for which this Warrant is then exercisable by the
Purchase Price.

      1.2. Partial Exercise. This Warrant may be exercised in part by surrender
of this Warrant in the manner and at the place provided in subsection 1.1 except
that the amount payable by the holder on such partial exercise shall be the
amount obtained by multiplying (a) the number of shares of Common Stock
designated by the holder in the subsection at the end hereof by (b) the Purchase
Price. On any such partial exercise the Company at its expense will forthwith
issue and deliver to or upon the order of the holder hereof a new Warrant or
Warrants of like tenor, in the name of the holder hereof or as such holder (upon
payment by such holder of any applicable transfer taxes) may request, calling in
the aggregate on the face or faces thereof for the number of shares of Common
Stock for which such Warrant or Warrants may still be exercised.

      1.3. Company Acknowledgment. The Company will, at the time of the exercise
of the Warrant, upon the request of the holder hereof acknowledge in writing its
continuing obligation to afford to such holder any rights to which such holder
shall continue to be entitled after such exercise in accordance with the
provisions of this Warrant. If the holder shall fail to make any such request,
such failure shall not affect the continuing obligation of the Company to afford
to such holder any such rights.

      1.4 Trustee for Warrant Holders. In the event that a bank or trust company
shall have been appointed as trustee for the holder of this Warrant pursuant to
subsection 4.2, each bank or trust company shall have all the powers and duties

name for the account of the Company or such successor person as may be entitled
thereto, all amounts otherwise payable to the Company or such successor, as the
case may be, on exercise of this Warrant pursuant to this section 1.

      2. Delivery of Stock Certificates, etc., on Exercise. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within 10 days thereafter, the Company

cause to be issued in the name of and delivered to the holder hereof, or as such
holder (upon payment by such holder of any applicable transfer taxes) may
direct, a certificate or certificates for the number of fully paid and
nonassessable shares of Common Stock (or Other Securities) to which such holder
shall be entitled on such exercise, plus, in lieu of any fractional share to
which such holder would otherwise be entitled, cash equal to such fraction
multiplied by the then current market value of one full share, together with any
other stock or other securities and property (including cash, where applicable)
to which such holder is entitled upon such exercise pursuant to section 1 or
otherwise.

      3. Adjustment for Dividends in Other Stock, Property, etc.:
Reclassification, etc. In case at any time or from time to time, the holders of
Common Stock (or Other Securities) shall have received, or (on or after the
record date fixed for the determination of shareholders eligible to receive)
shall have become entitled to receive, without payment therefor,

            (a) other or additional stock or other securities or property (other
than cash) by way of dividend, or

            (b) any cash (excluding cash dividends payable solely out of
earnings or earned surplus of the Company), or

            (c) other or additional stock or other securities or property
(including cash) by way of spin-off, split-up, reclassification,
recapitalization, combination of shares or similar corporate rearrangement,
other than additional shares of Common Stock (or Other Securities) issued as a
stock dividend or in a stock split, then and in each such case the holder of
this Warrant, on the exercise hereof as provided in section 1, shall be entitled
to receive the amount of stock and other securities and property (including cash
in the cases referred to in subdivisions (b) and (c) of this section 3) which
such holder would hold on the date of such exercise if on the date hereof he had
been the holder of record of the number of shares of Common Stock called for on
the face of this Warrant and had thereafter, during the period from the date
hereof to and including the date of such exercise, retained such shares and all
such other or additional stock and other securities and property (including cash
in the cases referred to in subdivisions (b) and (c) of this section 3)
receivable by him as aforesaid during such period, giving effect to all
adjustments called for during such period by section 4.

      4. Adjustment for Reorganization, Consolidation, Merger, etc.

from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company, then, in each such
case, the holder of this Warrant, on the exercise hereof as provided in section
1 at any time after the consummation of such reorganization, consolidation or
merger or the effective date of such dissolution, as the case may be, shall
receive, in lieu of the Common Stock (or Other Securities) issuable on such
exercise prior to such consummation or such effective date, the stock and other
securities and property (including cash) to which such holder would have been
entitled upon such

further adjustment as provided in section 3.

the transfer of all or substantially all of its properties or assets, the
Company, prior to such dissolution, shall at its expense deliver or cause to be
delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of the Warrant after the effective date of
such dissolution pursuant to this section 4 to a bank or trust company, as
trustee (or the holder or holders of the Warrant.
