WHEREAS, the Board of Directors of this Corporation has previously authorized
the issuance of Series B Preferred Stock and has filed a Certificate of
Designation relating thereto with the Secretary of State of Delaware on June 21,
1996;

WHEREAS, no shares of such Series B Preferred Stock have been issued; and

WHEREAS, the Board of Directors of this Corporation hereby determines that it is
in the best interests of this Corporation that this Amended Certificate of
Designation completely supersede, amend and restate the aforementioned
Certificate with respect to the Series B Preferred Stock as follows:

WHEREAS, the Certificate of Incorporation of this Corporation, as restated,
authorizes this Corporation to issue 2,000,000 shares of preferred stock, par
value $.01 per share;

WHEREAS, the Certificate of Incorporation of this Corporation, as restated,
authorizes the Board of Directors of this Corporation to determine the
designations, powers, preferences, rights and privileges of such preferred
stock, including the rights, if any, of the holders thereof with respect to
dividends, liquidation, voting, redemption and conversion;

WHEREAS, the Board of Directors of this Corporation has been previously
authorized to issue preferred stock of this Corporation in series;

WHEREAS, pursuant to that certain Agreement and Plan of Reorganization (the
"Reorganization Plan") made and entered into as of April 12, 1996, by and among
this Corporation, Interfilm Acquisition Corp., the wholly-owned subsidiary of
this Corporation and a New Mexico corporation ("InSub") and RhoMed





    



Incorporated, a New Mexico corporation ("RhoMed"), this Corporation intends to
merge InSub with and into RhoMed whereupon the separate existence of InSub shall
cease, and RhoMed shall be the surviving corporation (the "Merger");

WHEREAS, in connection with the Merger, this Corporation intends to issue
certain shares of preferred stock to the shareholders of RhoMed; and

WHEREAS, to provide for such issuance, the Board of Directors hereby determines
that it is in the best interests of this Corporation to designate 720,033 shares
of Series B Preferred Stock upon the terms and conditions contained in this
Certificate of Designation.

NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors hereby fixes and
determines the designation of, the number of shares constituting, and the
powers, preferences, rights and privileges relating to, said Series B Preferred
Stock as follows:

                1. DESIGNATION AND NUMBER OF SHARES. The Board of Directors
hereby creates a series of preferred stock designated as Series B Preferred
Stock which shall consist of 720,033 shares.

                2. DIVIDEND RIGHTS. Each of the shares of the Series B Preferred
Stock, on an "as-converted" and pro-rata basis, shall participate with the
shares of the Common Stock of this Corporation in any dividends paid by this
Corporation on such Common Stock; provided, however, that no shares of the
Series B Preferred Stock shall participate in any manner with any direct or
indirect distribution to the shares of the Common Stock of this Corporation of
any of the assets of the Interfilm Stockholders Limited Partnership, a Delaware
limited partnership.

                3. RIGHTS OF LIQUIDATION. The rights of liquidation of the
Series B Preferred Stock shall be junior to the rights of liquidation of the
Series A Preferred Stock of this Corporation. Upon any voluntary or involuntary
liquidation, dissolution or winding up of this Corporation, the holders of the
Series B Preferred Stock shall be entitled, before any distribution of assets
shall be made to the holders of Common Stock or any other shares of this
Corporation ranking junior to the Series B Preferred Stock but after the
exercise of the rights of liquidation of the Series A Preferred Stock, to
receive an amount equal to $.01 (the par value of the Series B Preferred Stock)
per share of Series B Preferred

                                       2




    



Stock so held. After the full preferential liquidation amount has been paid to,
or determined or set apart for, the holders of the Series B Preferred Stock, the
remaining assets shall be paid to the holders of all classes of Common Stock and
other shares of this Corporation ranking junior to the Series B Preferred Stock.
In the event the assets of this Corporation, after being valued at the highest
value permitted by law and after the exercise of the rights of liquidation of
the Series A Preferred Stock, are insufficient to pay the full preferential
liquidation amount required to be paid to the holders of Series B Preferred
Stock, the entire remaining assets shall be paid to the holders of Series B
Preferred Stock on a pro-rata basis, and the holders of Common Stock and any
other shares of this Corporation ranking junior to Series B Preferred Stock
shall receive nothing. Neither the merger, consolidation or reorganization of
this Corporation nor the sale, lease or conveyance of all or substantially all
of this Corporation's assets shall be deemed a liquidation, dissolution or
winding up of this Corporation within the meaning of this Section.

                4. VOTING RIGHTS.

                        (a) Holders of the Series B Preferred Stock will, to the
extent permitted by law, be entitled to vote as a single class with the Common
Stock of this Corporation on matters submitted to a vote of stockholders of this
Corporation as if the Series B Preferred Stock were converted into shares of
Common Stock pursuant to the terms of this Certificate of Designation.

                        (b) So long as any of the shares of the Series B
Preferred Stock are outstanding, this Corporation will not, without the
affirmative vote or consent of the holders of at least fifty percent (50%) of
the shares of the Series B Preferred Stock (the holders of such shares voting or
consenting separately as a class) at the time outstanding, given in person or by
proxy, either in writing or by a resolution adopted at a meeting called for the
purpose of amending, altering or repealing any of the provisions of this
Corporation's Certificate of Incorporation, By-laws or the resolution providing
for the issuance of such shares, pass any stockholder resolution, including such
action effected by merger of similar transaction in which this Corporation is
the surviving corporation, if such amendment or resolution would affect
adversely the preferences, special rights or powers of the shares of the Series
B Preferred Stock.

                5. REDEMPTION RIGHTS. The shares of the Series B Preferred Stock
shall have no redemption rights.

                6. CONVERSION. The shares of Series B Preferred Stock, as
adjusted for any stock dividends, combinations or splits, shall automatically
convert into Common Stock of this Corporation as follows:

                                        3



    



                        (a) Each share of the Series H Preferred Stock shall
automatically convert into 184,332,593 shares of Common Stock of this
Corporation upon the filing of an Amended Certificate of Incorporation (the
"Amended Certificate") that provides for, among other things, an increase in the
number of shares of Common Stock which this Corporation will be authorized to
issue, as required under Section 5.13 of the Reorganization Plan.

                        (b) For every one (1) share of the Common Stock of this
Corporation which is issued and outstanding as of the closing date of the Merger
that is in excess of an aggregate of four million four hundred fifty-seven
thousand five hundred (4,457,500) shares plus any shares of the Common Stock
which are issued upon exercise or conversion of all derivative securities of
this Corporation that are convertible into or exchangeable for any shares of
this Corporation's or InSub's capital stock, the total number of shares of the
Common Stock into which the Series B Preferred Stock will convert will increase
by eleven and one-half (11.5) shares of Common Stock.

                        (c) For every Twenty-Five Cents ($0.25) in excess of
Fifty Thousand Dollars ($50,000.00) in the aggregate of actual, contingent or
other liabilities, obligations or commitments of this Corporation and InSub
collectively outstanding as of the closing date of the Merger, as determined by
RhoMed after consultation with this Corporation, the total number of shares of
Common Stock into which the Series B Preferred Stock will convert will increase
by an additional 1,235,028,373 shares of Common Stock.

                        (d) Cash, in the amount of Fourteen Cents ($0.14) per
share of Series B Preferred Stock, will be issued, on a pro rata basis, in lieu
of fractional shares upon the conversion of the Series B Preferred Stock into
Common Stock.

                        (e) In order to convert the shares of Series B Preferred
Stock into shares of Common Stock, the holder thereof shall surrender at any
office of this Corporation the certificate or certificates therefore, duly
endorsed or assigned to this Corporation or in blank.

                        (f) Shares of Series B Preferred Stock shall be deemed
to have been converted as provided herein notwithstanding the failure of any
holder to surrender such holder's certificates, and the person or persons
entitled to receive Common Stock issuable upon the effective date of such
conversion shall be treated for all purposes as the record holder or holders of
such Common Stock at such time. As promptly as practicable on or after the
effective date of conversion, this Corporation shall issue and shall deliver at
said office a certificate or certificates for the number of full shares of
Common Stock issuable upon such conversion.

                                          4




    



                        (g) Upon the filing of the Amended Certificate, this
Corporation shall at all times reserve and keep available, free from preemptive
rights, out of its authorized but unissued Common Stock, for the purpose of
effecting the conversion of the shares of Series B Preferred Stock, the full
number of shares of Common Stock then deliverable upon the conversion of all
shares of Series B Preferred Stock then outstanding.

                        (h) This Corporation will pay any and all taxes that may
be payable in respect of the issue or delivery of shares of Common Stock on
conversion of shares of the Series B Preferred Stock pursuant hereto. This
Corporation shall not, however, be required to pay any tax which may be payable
in respect of any transfer involved in the issue and delivery of shares of
Common Stock in a name other than that in which the shares of the Series B
Preferred Stock so converted were registered, and no such issue or delivery
shall be made unless and until this person requesting such issue has paid to
this Corporation the amount of any such tax, or has established, to the
satisfaction of this Corporation, that such tax has been paid.

                        (i) For the purpose of this Certificate, the term
"Common Stock" shall include any stock of any class of this Corporation which
has no preference in respect of dividends or of amounts payable in the event of
any voluntary or involuntary liquidation, dissolution or winding up of this
Corporation and which is not subject to redemption by this Corporation. However,
shares issuable on conversion of shares of the Series B Preferred Stock shall
include only shares of the class designated as Common Stock of this Corporation
as the date hereof or shares of any class or classes resulting from any
reclassification or reclassifications thereof and which have no preference in
respect of dividends or of amounts payable in the event of any voluntary or
involuntary liquidation, dissolution or winding up of this Corporation and which
are not subject to redemption by this Corporation; provided that if at any time
there shall be more than one such resulting class, the shares of each such class
then so issuable shall be substantially in the proportion which the total number
of shares of such class resulting from all such reclassifications bears to the
total number of shares of all such classes resulting from all such
reclassifications.

RESOLVED FURTHER, that the officers of this Corporation are each authorized to
do or cause to be done all such acts or things and to make, execute and deliver
or cause to be made, executed and delivered all such agreements, documents,
instruments and certificates in the name and on behalf of this
