Item 2.        Management's Discussion and Analysis of Financial Condition and 
               Results of Operations.

Liquidity and Capital Resources
- -------------------------------

               The Company's primary source of funds to date has been proceeds
from the sale of its securities, investment income on such proceeds and loans.
The Company will require additional funds in the immediate future to continue
its operations, pay accrued expenses, including salary, rent and lease payments,
to develop further its products and to market its products. The Company may
receive a portion of such funds from sales of the SALITRON System. The Company
is considering obtaining funds through venture capital or other private or
public financing, joint venture or merger transactions, the sale of certain
assets and research and development partnership financing. The Company has
engaged a consultant to assist in obtaining additional funding. There is no
assurance that any such funding or other financing will be completed, or that
funding to carry out these activities will be on terms acceptable to Biosonics.

               The Company does not have any material commitments for capital
expenditures, although the Company may make capital expenditures during 1996 or
in connection with the manufacture of the SALITRON and CYSTOTRON Systems, if
funds are available. The extent of the development or testing, if any, of the
Company's other devices will depend on the availability of funds.

Results of Operations
- ---------------------

               Net development stage expenses for the nine and three months
ended September 30, 1996 ($501,091 and $280,853 respectively) were higher than
those for the comparable periods of the prior year ($371,989 and $104,786
respectively) due to funds spent on the Special Shareholders meeting and the
hiring of a Public Relations company. Other development stage expenses include
primarily salaries, rent, supplies, transfer agent fees, manufacturing,
marketing, public relations and travel expenses. The Company's professional fees
for the nine and three months ended September 30, 1996 ($109,691 and $72,691
respectively) were higher than those for the comparable period of the prior year
($62,004 and $8,480 respectively) due to legal and accounting expenses incurred
for the Special Shareholders meeting and a retainer paid to the new attorneys
hired as counsel to the Company on securities related issues. The Company's
sales for the nine and three months ended September 30,1996 were $34,911 and
$5,786 respectivly as compared to $45,716 and $23,190 respectively for the same
periods of the prior year. The decrease in sales resulted primarily from not
having available funds to continue the marketing program for its SALITRON
System.

PART II        OTHER INFORMATION

Item 1.        Legal Proceedings

               Reference is made to Part II Item 1 of the Company's Form 10-Q
quarterly report for the period ending March 31, 1996.

Item 2.        Changes in Securities.

               In July 1996, The Company amended its Articles of Corporation
pursuant to which the company increased the authorized number of shares of
Common Stock from 250,000,000 shares to 750,000,000 shares. On July 30, 1996,
all stock that had been previously purchased but unissued due to the
unavailability of shares of authorized Common Stock of the Company were issued.
The total number of shares issued was 12,900,000 shares. In addition, all
holders of Preferred Stock, A Series, B Series and D Series, converted their
Preferred

                                       11
<PAGE>
 
Shares into Common Stock of the Company, pursuant to the formula set forth in
their respective Preferred Stock Agreements. The total number of Common Shares
issued as a result of the conversion of all the Preferred Stock was 28,725,000
shares, including 7,000,000 shares to IMRC and 4,375,000 shares to Jack Paller
pursuant to the conversion of their Preferred Stock Series B.

               In addition to the above shares, the Company issued an aggregate
of 300,000 Common Stock shares to the Salitron Advisory Board, an aggregate of
650,000 shares of Common Stock were issued to three outside consultants in
connection with financial planning and consulting services to be provided to the
Company. Also IMRC Holdings, Inc. issued 550,000 shares of the Company's Common
Stock held by it to two outside consultants for certain advertising and public
relation services. Further, the Company issued an aggregate of 280,000 shares to
three doctors for medical consulting services rendered. An aggregate of
14,200,000 shares of Common Stock were issued to eighteen persons who wished to
acquire stock but at the time, the company was restricted from issuance since
this issuance would have been more than the total authorized.

               The Company also issued 18,368,820 shares of Common Stock to
approximately 25 individuals in conversion of loans. The loans were originally
to IMRC Holdings, Inc. which then loaned the money to the Company to use for
working capital. None of the individuals making the loans were officers,
directors or affiliates of the Company. The terms of the loans allowed the loans
to be converted into Common Stock of Biosonics, Inc. held by IMRC Holdings. In
consideration of the Company assuming the obligations under the loans, including
the obligation to issue stock upon conversion of the loans, IMRC Holdings,
transferred to the Company 18,368,820 shares of Biosonics Common Stock owned by
IMRC Holdings and canceled the indebtedness from the Company to IMRC Holdings.

Item 4.        Submission of matters to a vote of security holders.

               The Company held a Special Meeting of Shareholders on July 16,
1996. At the meeting, two proposals were submitted to the shareholders. The
first proposal was to amend the Articles of Incorporation of the Company to
increase the authorized number of shares of Common Stock from 250,000,000 shares
to 750,000,000 shares. The second proposal was to amend the Articles of
Incorporation to give the Board of Directors the authority to effect a reverse
split, the ratio to be determined by the Board of Directors, but the ratio would
be no less than 1 for 10 shares or more than 1 for 150 shares. The Proposal
would give the Board of Directors one year to decide and effectuate the stock
split, if it decides such stock split is in the best interest of the Company.

               Both proposals were approved by the shareholders. The first
proposal, the increase in the authorized number of shares, was approved by a
vote of 172,133,873 for 1,271,596 against, 223,233 abstaining and 0 broker
non-votes. The second proposal, amending the Articles of Incorporation to give
the Board of Directors the power to effect a reverse stock split, was approved
by a vote of 172,133,873 for 1,661,647 against, 196,197 abstaining and 0 broker
non-votes.

that:

               (a)  The Conversion Shares shall be deemed to have been issued to
the person exercising such conversion privilege upon the date of surrender (the
"Conversation Date") of the certificates representing the Preferred Stock to be
converted in accordance with this Section 2, and the person exercising such
conversion privilege shall be deemed for all purposes to have become the record
holder of such Conversion Shares at the Conversion Date, unless pursuant to
Section 2.2 a different person is specified.

               (b)  All Conversion Shares will, upon issuance, be fully paid and
non-assessable.

     3.   Anti-Dilution.
          ------------- 

          3.1  Subdivision or Combination of Stock.  In case the Corporation
               -----------------------------------                          
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the number of Conversion Shares into which the
Preferred Stock is converted immediately prior to such subdivision shall be
proportionately increased, and, in case the outstanding shares of Common Stock
of the Corporation shall be combined into a smaller number of shares, the number
of Conversion Shares into which the Preferred Stock is converted immediately
prior to such combination shall be proportionately reduced.

right to acquire and receive, upon conversion of the Preferred Stock such shares
of stock, securities or assets as would have been issuable or payable (as part
of the reorganization, reclassification, consolidation or merger) with respect
to or in exchange for such number of outstanding shares of the Corporation's
Common Stock as would have been received upon conversion of the Preferred Stock
immediately before such reorganization, reclassification, consolidation or
merger.  In any such case appropriate provision shall be made with respect to
the rights and interests of the holders of the Preferred Stock to the end that
the provisions hereof (including without limitation provisions for adjustments
of the number of Conversion Shares acquirable and receivable upon the conversion
of the Preferred Stock) shall thereafter be applicable as nearly as possible in
relation to any shares of stock, securities or assets thereafter deliverable
upon the conversion of the Preferred Stock.

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

                                   EXHIBIT A

                  RESOLUTION ESTABLISHING AND DESIGNATING THE
             PREFERRED STOCK - SERIES C AND FIXING AND DETERMINING
                  THE RELATIVE RIGHTS AND PREFERENCES THEREOF


     RESOLVED, that pursuant to the authority expressly vested in the Board of
Directors by the Corporation's Articles of Incorporation, there is hereby
established a series of one Thousand (1,000) shares of preferred stock of the
Corporation, par value one Dollar ($1.00) per share, to be known as "Preferred
Stock - Series C".  The rights, designations, preferences, qualifications,
privileges, limitations and conversion rights thereof are as follows:

     I.     Designation and Amount. There shall be a series of the Corporation's
            ----------------------
class of Preferred Stock, par value one Dollar ($1.00) per share, which shall
consist of One thousand (1,000) shares and shall be designated as "Preferred
Stock Series C" (hereinafter the "Preferred Stock").

     II.    Terms Applicable To Preferred Stock.
            ----------------------------------- 

            1.   Voting Rights. Except as otherwise expressly provided herein or
                 -------------
as required by law, holders of Preferred Stock shall have the right to vote on
all matters as to which holders of Common Stock have a right to vote, and such
voting rights shall be exercised on an as-converted basis (i.e., as though the
Preferred Stock had been converted and such holders held the Common Stock
issuable upon such conversion). Holders of Preferred Stock shall have no right
to vote as a class except as required by law.

            2.   Conversion.
                 ---------- 

                 2.1   Conversion Rights. Each share of the Preferred Stock
                       -----------------
shall be convertible into Ten Thousand (10,000) shares of the Common Stock
("Conversion Shares") of the Corporation as hereinafter set forth, subject to
the provisions of Section 3 by which the Preferred Stock may be converted into a
larger or smaller number of Conversion Shares upon the occurrence of certain
events described therein.

                 2.2   Conversion Procedure.  Each certificate representing
                       --------------------                                
Preferred Stock may be converted in whole or in part (but not as to any
fractional part of any share of Preferred Stock).  The certificate representing
the Preferred Stock to be converted shall be endorsed to reflect the conversion
of all or such portion thereof as the holder determines to convert and shall be
delivered to the Corporation at its principal office.  Each request for
conversion shall be accompanied by the holder's acknowledgment in form and
substance satisfactory to the Corporation that (i) the Conversion Shares are
being purchased for investment and not for distribution or resale (other than a
distribution or resale which, in the opinion of counsel satisfactory to the
Corporation, may be made without violating the registration provisions of the
Securities Act of 1933, as amended, or any applicable state securities law
(collectively, the "Acts"), (ii) the holder has been advised and understands
that (A) the
<PAGE>
 
Conversion Shares have not been registered under the Acts and are "restricted
securities" within the meaning of Rule 144 under the Securities Act of 1933, as
amended, and are subject to restrictions on transfer, and (B) the Corporation is
under no obligation to register the Conversion Shares under the Acts or to take
any action which would make available to the Optionee any exemption from such
registrations, (iii) such Conversion Shares may not be transferred without
compliance with all applicable federal and state securities laws, and (iv) an
appropriate legend referring to the foregoing restrictions on transfer may be
endorsed on the certificates. Notwithstanding the foregoing, if the Corporation
determines that issuance of Conversion Shares should be delayed pending (a)
registration under federal or state securities laws, (b) the receipt of an
acceptable legal opinion that an appropriate exemption from such registration is
available, (c) the listing or inclusion of the Conversion Shares on any
securities exchange or in an automated quotation system, or (d) the consent or
approval of any governmental regulatory body whose consent or approval is
necessary in connection with the issuance of the Conversion Shares, the
Corporation may defer issuance of the Conversion Shares until the applicable
event or events have occurred.

                 2.3   Conversion Period.  Except as herein expressly provided
                       -----------------                                      
otherwise, any holder of Preferred Stock may exercise the conversion rights of
all or any portion of the Preferred Stock held by such holder at any time or
from time to time after the date of issuance.

                 2.4   Authorization and Issuance. The Corporation covenants and
                       --------------------------
agrees that:

                       (a) The Conversion Shares shall be deemed to have been
issued to the person exercising such conversion privilege upon the date of
surrender (the "Conversion Date") of the certificates representing the Preferred
Stock to be converted in accordance with this Section 2, and the person
exercising such conversion privilege shall be deemed for all purposes to have
become the record holder of such Conversion Shares at the Conversion Date.

                       (b) All Conversion Shares will, upon issuance, be fully
paid and non-assessable.

            3.   Anti-Dilution.
                 ------------- 

                 3.1   Subdivision Combination of Stock.  In the event that the
                       --------------------------------                        
Corporation shall at any time subdivide its outstanding shares of Common Stock
into a greater number of shares, the number of Conversion Shares into which the
Preferred Stock is convertible shall be proportionately increased, and, in the
event that the outstanding shares of Common Stock of the Corporation shall at
any time be combined into a smaller number of shares, the number of Conversion
Shares into which the Preferred Stock is convertible shall be proportionately
reduced.
<PAGE>
 
                 3.2   Reorganization, Reclassification, Consolidation or
                       --------------------------------------------------
Merger. If there should occur any capital reorganization or reclassification of
- ------
the capital stock of the Corporation, or consolidation or merger of the
Corporation with another corporation, then, as a condition of such
reorganization, reclassification, consolidation or merger, lawful and adequate
provision shall be made whereby the holders of the Preferred Stock shall
thereafter have the right to acquire and receive, upon conversion of the
Preferred Stock, such shares of stock, securities or assets as would have been
issuable or payable (as part of the reorganization, reclassification,
consolidation or merger) with respect to or in exchange for such number of
outstanding shares of the Corporation's Common Stock as would have been received
upon conversion of the Preferred Stock immediately before such reorganization,
reclassification, consolidation or merger. In any such case appropriate
provisions shall be made with respect to the rights and interests of the holders
of the Preferred Stock to the end that the provisions hereof (including without
limitation provisions for adjustments of the number of Conversion shares
acquirable and receivable upon the conversion of the Preferred Stock) shall
thereafter be applicable as nearly as possible in relation to any shares of
stock, securities or assets thereafter deliverable upon the conversion of the
Preferred Stock.

            4.   Liquidation.
                 ----------- 

                 4.1   Rights of Holders of Preferred Stock. In the event of any
                       ------------------------------------
voluntary or involuntary liquidation (whether complete or partial), dissolution
or winding up of the Corporation, the holders of the Preferred Stock shall be
entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders an amount in cash equal to One Dollar ($1.00)
per share. No distribution shall be made on the Common Stock by reason of any
voluntary or involuntary liquidation (whether complete or partial), dissolution
or winding up of the Corporation unless each holder of Preferred Stock shall
have received all amounts to which such holder shall be entitled under this
Section 4.1.

                 4.2   Payments After Initial Distribution.  Should any amounts
                       -----------------------------------                     
be available for distribution after the payment to the holders of the Preferred
Stock required by Section 4.1, none of such additional amounts shall be paid to
the holders of the Preferred Stock.

                 4.3   Allocation of Liquidation Payments Among Holders of
                       ---------------------------------------------------
Preferred Stock.  If upon any voluntary or involuntary liquidation (whether
- ---------------                                                            
complete or partial), dissolution or winding up of the Corporation, the assets
of the Corporation available for distribution to holders of Preferred Stock (the
"Total Amount Available") shall be insufficient to pay the holders of
outstanding Preferred Stock the full amounts to which they shall be entitled
under Section 4.1, each holder of Preferred Stock shall be entitled to receive
an amount equal to the product derived by multiplying the Total Amount Available
by a fraction the numerator of which shall be the number of such holder's shares
of Preferred Stock and the denominator of which shall be the total number of
shares of Preferred Stock then outstanding.

            5.   Dividends on Preferred Stock. The holders of the Preferred
                 ----------------------------
Stock shall not be entitled to receive any dividends.
<PAGE>
 
            6.   General Provisions.
                 ------------------ 

                 6.1   Amendment and Waiver.  No change in the terms of the
                       --------------------                                
Preferred Stock shall be binding or effective unless such change shall have been
approved in writing by the holders of at least two-thirds (2/3) of the shares of
Preferred Stock then outstanding.

                 6.2   Replacement of Lost Certificates.  Upon receipt by the
                       --------------------------------                      
Corporation in a form reasonably satisfactory to it of (i) an indemnification by
the holder and (ii) evidence of the ownership of and the loss, theft,
destruction or mutilation of any certificate evidencing one or more shares of
Preferred Stock, the Corporation at its expense will execute and deliver in lieu
of such certificate, a new certificate of like kind, representing the number of
shares of Preferred Stock which shall have been represented by such lost,
stolen, destroyed, or mutilated certificate.

                 6.3   Rep1acement Certificates in Case of Conversion.  If any
                       ----------------------------------------------         
certificates representing Preferred Stock surrendered for the purpose of
exercising conversion rights represent more shares than actually converted, then
within thirty (30) days of surrender, the Corporation will, at its expense,
execute and deliver a new certificate or certificates of like kind for those
shares of Preferred Stock represented by the surrendered certificate but not
intended to be converted, provided, however, that the Corporation shall not be
required to issue any fractional shares of Preferred Stock.

required by law, holders of Preferred Stock shall have the right to vote on all
matters as to which holders of Common Stock have a right to vote, and such
voting rights shall be exercised on an as-converted basis (i.e., as though the

     2.   Conversion Rights.
          ----------------- 

          2.1  Description and Conversion Procedure. Each share of the Preferred
               ------------------------------------                             
Stock shall be convertible into Two Thousand (2,000) shares of the Common Stock
("Conversion Shares") of the Corporation as hereinafter set forth, (an aggregate
of Ten Million (10,000,000) shares), only after the Corporation has amended its
Articles of Incorporation to increase the number of authorized shares of Common
Stock so as to permit such conversion, and subject to the provisions of Section
3 by which the Preferred Stock may be converted into a larger or smaller number
of Conversion Shares upon the occurrence of certain events described therein.

          2.2  Conversion Procedure. Each certificate representing Preferred
               --------------------                                         
Stock may be converted in whole or in part. The certificate representing the
Preferred Stock to be converted shall be endorsed to reflect the conversion of
all or such portion thereof as the holder determines to convert and surrender to
the Corporation at its principal offices. If the Conversion Shares are not to be
issued in the name of the holder to whom the Preferred Stock is registered, such
holder shall state the name of the person to whom the certificate for the
Conversion Shares is to be issued, and if the Conversion Shares to be issued
shall not be all the Conversion Shares
<PAGE>
 
into which the Preferred Stock may be converted, the name of the person to whom
shall be issued a new certificate evidencing the balance of the Preferred Stock.

          2.3  Conversion Period. Except as herein expressly provided otherwise,
               -----------------                                                
any holder of Preferred Stock may exercise the conversion rights of all or any
portion of the Preferred Stock held by such holder at any time or from time to
time after the date of issuance and prior to the redemption of such shares of
Preferred Stock.

          2.4  Authorization and Issuance. The Corporation covenants and agrees
               --------------------------                                      
that:

               (a) The Conversion Shares shall be deemed to have been issued to
the person exercising such conversion privilege upon the date of surrender (the
"Conversion Date") of the certificates representing the Preferred Stock to be
converted in accordance with this Section 2, and the person exercising such
conversion privilege shall be deemed for all purposes to have become the record
holder of such Conversion Shares at the Conversion Date, unless pursuant to
Section 2.2 a different person is specified.

               (b) All Conversion Shares will, upon issuance, be fully paid and
non-assessable.

     3.   Anti-Dilution.
          ------------- 

          3.1  Subdivision or Combination of Stock. In case the Corporation
               -----------------------------------                         
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the number of Conversion Shares into which the
Preferred Stock is converted immediately prior to such subdivision shall be
proportionately increased, and, in case the outstanding shares of Common Stock
of the Corporation shall be combined into a smaller number of shares, the number
of Conversion Shares into which the Preferred Stock is converted immediately
prior to such combination shall be proportionately reduced.

          3.2  Reorganization, Reclassification, Consolidation or Merger. If
               ---------------------------------------------------------    
there should occur any capital reorganization or reclassification of the capital
stock of the Corporation, or consolidation or merger of the Corporation with
another corporation, then, as a condition of such reorganization,
reclassification, consolidation or merger, lawful and adequate provision shall
be made whereby the holders of the Preferred Stock shall thereafter have the
right to acquire and receive, upon conversion of the Preferred Stock such shares
of stock, securities or assets as would have been issuable or payable (as part
of the reorganization, reclassification consolidation or merger) with respect to
or in exchange for such number of outstanding shares of the Corporation's Common
Stock as would have been received upon the conversion of the Preferred Stock
immediately before such reorganization, reclassification, consolidation or
merger. In any such case appropriate provisions shall be made with respect to
the rights and interests of the holders of the Preferred Stock to the end that
the provisions hereof (including without limitation provisions for adjustments
of the number of Conversion Shares acquirable and receivable upon the conversion
of the Preferred Stock) shall thereafter be applicable as nearly as possible in
relation to any shares of stock, securities or assets thereafter deliverable
upon the conversion of the Preferred Stock.

(the "Redemption Price") the whole or any part of the Preferred Stock which

their predecessors in interest have not converted.

          4.2  Redemption Notice. At least fifteen (15) days prior to the date
               ------------------

Stock held of record by such holder which the Corporation proposes to redeem;
(ii) the Redemption Date; and (iii) the place at which the shares to be redeemed
may be surrendered in exchange for the Redemption Price for such shares if other

with respect to any Redemption which the Corporation may choose to make, the
Corporation shall become obligated to redeem the Preferred Stock specified in
the Redemption Notice on the date specified as the Redemption Date. Except as
set forth in the preceding sentence, the holders of the Preferred Stock shall

                    Resolution of the Board of Directors of
                     Biosonics, Inc. adopted April 16, 1996


                                   EXHIBIT A


                  RESOLUTION ESTABLISHING AND DESIGNATING THE
             PREFERRED STOCK - SERIES B AND FIXING AND DETERMINING
                  THE RELATIVE RIGHTS AND PREFERENCES THEREOF


          RESOLVED, that the series of Preferred Stock of the Company known as
          the "Preferred Stock-Series B," established by resolution of the Board
          of Directors adopted June 27, 1989, as amended by Resolution adopted
          September 6, 1989, is hereby further amended to add the following
          provision allowing holders thereof conversion rights ("Conversion
          Rights") at $.03 a share based on the Redemption Price of $105.00 per
          share, as follows:

               6.   Conversion Rights.
                    ----------------- 

                    6.1  Description and Conversion Procedure. Each share of the
                         ------------------------------------                   
          Preferred Stock shall be convertible into Three Thousand Five Hundred
          (3,500) shares of the Common Stock ("Conversion Shares") of the
          Corporation as hereinafter set forth, only after the Corporation has
          amended its Articles of Incorporation to increase the number of
          authorized shares of Common Stock so as to permit such conversion, and
          subject to the provisions of Section 7 by which the Preferred Stock
          may be converted into a larger or smaller number of Conversion Shares
          upon the occurrence of certain events described therein.


                    6.2  Conversion Procedure. Each certificate representing
                         --------------------                               
          Preferred Stock may be converted in whole or in part. The certificate
          representing the Preferred Stock to be converted shall be endorsed to
          reflect the conversion of all or such portion thereof as the holder
          determines to convert and surrender to the Corporation at its
          principal offices.  If the Conversion Shares are not to be issued in
          the name of the holder to whom the Preferred Stock is registered, such
          holder shall also state the name of the person to whom the certificate
          for the Conversion Shares is to be issued, and if the Conversion
          Shares to be issued shall not be all the Conversion Shares into which
          the Preferred Stock may be converted, the name of the person to whom
          shall be issued a new certificate evidencing the balance of the
          Preferred Stock.


                    6.3  Conversion Period.  Except as herein expressly provided
                         -----------------                                      
          otherwise, any holder of Preferred Stock may exercise the conversion
          rights of all or any portion of the Preferred
<PAGE>
 
          Stock held by such holder at any time or from time to time after the
          date of issuance and prior to the redemption of such shares of
          Preferred Stock.

                    6.4  Authorization and Issuance.   The Corporation covenants
                         --------------------------                             
          and agrees that:

                    (a) The Conversion Shares shall be deemed to have been
          issued to the person exercising such conversion privilege upon the
          date of surrender (the "Conversion Date") of the certificates
          representing the Preferred Stock to be converted in accordance with
          this Section 6, and the person exercising such conversion privilege
          shall be deemed for all purposes to have become the record holder of
          such Conversion Shares at the Conversion Date, unless pursuant to
          Section 6.2 a different person is specified.

                    (b) All Conversion Shares will, upon issuance, be fully paid
          and non-assessable.

               7.   Anti-Dilution.
                    ------------- 

                    7.1  Subdivision or Combination of Stock. In case the
                         -----------------------------------             
          Corporation shall at any time subdivide its outstanding shares of
          Common Stock into a greater number of shares, the number of Conversion
          Shares into which the Preferred Stock is converted immediately prior
          to such subdivision shall be proportionately increased, and, in case
          the outstanding shares of Common Stock of the Corporation shall be
          combined into a smaller number of shares, the number of Conversion
          Shares into which the Preferred Stock is converted immediately prior
          to such combination shall be proportionately reduced.


                    7.2  Reorganization, Reclassification, Consolidated or
                         -------------------------------------------------
          Merger. If there should occur any capital reorganization or
          ------                                                     
          reclassification of the capital stock of the Corporation, or
          consolidation or merger of the Corporation with another corporation,
          then, as a condition of such reorganization, reclassification,
          consolidation or merger, lawful and adequate provision shall be made
          whereby the holders of the Preferred Stock shall thereafter have the
          right to acquire and receive, upon conversion of the Preferred Stock
          such shares of stock, securities or assets as would have been issuable
          or payable (as part of the reorganization, reclassification,
          consolidation or merger) with respect to or in exchange for such
          number of outstanding shares of the Corporation's Common Stock as
          would have been received upon the conversion of the Preferred Stock
          immediately before such reorganization, reclassification,
          consolidation or merger.  In any such case appropriate provisions
          shall be made with respect to the rights and interests of the holders
          of the Preferred Stock to the end that the provisions hereof
          (including without limitation
<PAGE>
 
          provisions for adjustments of the number of Conversion Shares
          acquirable and receivable upon the conversion of the Preferred Stock)
          shall thereafter be applicable as nearly as possible in relation to
          any shares of stock, securities or assets thereafter deliverable upon
          the conversion of the Preferred Stock.

          FURTHER RESOLVED, that any officer of this Company along or together
          with any other officer, is hereby authorized and directed to execute
          and deliver to the Department of State, Commonwealth Pennsylvania, a
          Statement Affecting Class or Series of Shares, indicating the

ownership of and the loss, theft, destruction or mutilation of any certificate
evidencing one or more shares of B Preferred Stock, the Corporation at its
expense will execute and deliver in lieu of such certificate, a new certificate
of like kind, representing the number of shares of B Preferred Stock which shall
have been represented by such lost, stolen, destroyed, or mutilated certificate.

               5.3  Replacement Certificate in Case of Redemption.  If any
                    ---------------------------------------------         
certificates representing B Preferred Stock surrendered pursuant to a Redemption

the Corporation will, at its expense execute and deliver a new certificate or
certificates of like kind for those shares of B Preferred Stock represented by
the surrendered certificate but not intended to be redeemed, provided, however,
that the Corporation may pay cash based on the Redemption Price, as applicable
in lieu of any fractional shares of B Preferred Stock represented by such
surrendered certificates but not intended to be redeemed.

of the reorganization, reclassification consolidation or merger) with respect to
or in exchange for such number of outstanding shares of the Corporation's Common
Stock as would have been received upon the conversion of the Preferred Stock
immediately before such reorganization, reclassification, consolidation or
merger.  In any such case appropriate provisions shall be made with respect to
the rights and interests of the holders of the Preferred Stock to the end that
the provisions hereof (including without limitation provisions for adjustments
of the number of Conversion Shares acquirable and receivable upon the conversion
of the Preferred Stock) shall thereafter be applicable as nearly as possible in
