Item 5.  Other Events.
- ---------------------

     On December 31, 1999, NutraMax Products, Inc. (the "Company") completed the
sale of its Ophthalmics Division, Optopics Laboratories, to Miza Pharmaceuticals
USA, Inc.  The net proceeds of the sale will be applied to pay down certain
amounts under the Company's credit facility with its senior lenders.  The
Company decided early last year to divest the Opthalmics Division as a necessary
step to improve the financial performance of the Company and to position it for
future growth in its existing more profitable core areas.

due to the date hereof have been paid; (b) neither the lessor nor, to the best
of the knowledge of the Vendor, the lessee is in default thereunder; (c) no

except for the Contracts and the Leases.

To the best of the knowledge of the Vendor, no person from whom consent to
assignment and novation of any of the Contracts identified in Schedule 5.16 has
expressed reservations regarding the giving of such consent.

respect, and there exists no default or event of default or event, occurrence,
condition or act (including the sale of the Assets hereunder) which, with the
giving of notice or the lapse of time would become a default or event of default
thereunder, which would have a material adverse effect on the Assets, except for
the necessity of obtaining the Consents. The Vendor has not violated or

                    and sale contemplated hereunder, provided that the Claim or
                    Loss is not the result of any failure by the Purchaser to
                    pay the Assumed Liabilities.

10.4  Indemnification Proceedings

      (a)    Any Party seeking indemnification under this Article (the
             "indemnified party") shall forthwith notify the Party against whom
             a Claim for indemnification is sought hereunder (the indemnifying
             party") in writing, which notice shall specify, in reasonable
             detail, the nature and estimated
<PAGE>

                                      -33-

             amount of the Claim. If a Claim by a third party is made against an
             indemnified party, and if the indemnified party intends to seek
             indemnity with respect thereto under this Article, the indemnified
             party shall promptly (and in any case within thirty (30) days of
             such claim being made) notify the indemnifying party of such with
             reasonable particulars. The indemnifying party shall have thirty
             (30) days after receipt of such notice to undertake, conduct and
             control, through counsel of its own choosing and at its own
             expense, the settlement or defence thereof, and the indemnified
             party shall cooperate with it in connection therewith; except that
             with respect to settlements entered into by the indemnifying party
             (i) the consent of the indemnified party shall be required if the
             settlement provides for equitable relief against the indemnified
             party, which consent shall not be unreasonably withheld or delayed;
             and (ii) the indemnifying party shall obtain the release of the
             indemnified party. If the indemnifying party undertakes, conducts
             and controls the settlement or defence of such Claim (i) the
             indemnifying party shall permit the indemnified party to
             participate in such settlement or defence through counsel chosen by
             the indemnified party, provided that the fees and expenses of such
             counsel shall be borne by the indemnified party; and (ii) the
             indemnifying party shall promptly reimburse the indemnified party
             for the full amount of any loss resulting from any Claim and all
             related expenses (other than the fees and expenses of counsel as
             aforesaid) incurred by the indemnified party. The indemnified party
             shall not pay or settle any Claim so long as the indemnifying party
             is reasonably contesting any such Claim in good faith and on a
             timely basis. Notwithstanding the two immediately preceding
             sentences, the indemnified party shall have the right to pay or
             settle any such Claim, provided that in such event it shall waive
             any right to indemnity therefor from the indemnifying party.

      (b)    With respect to third party Claims, if the indemnifying party does
             not notify the indemnified party within thirty (30) days after the
             receipt of the indemnified party's notice of a Claim of indemnity
             hereunder that it elects to undertake the defence thereof, the
             indemnified party shall have the right, but not the obligation, to
             contest, settle or compromise the Claim in the exercise of its
             reasonable judgment at the expense of the indemnifying party.

      (c)    In the event of any Claim by a third party against an indemnified
             party, the defence of which is being undertaken and controlled by
             the indemnifying party, the indemnified party shall use all
             reasonable efforts to make available to the indemnifying party
             those employees whose assistance, testimony or presence is
             necessary to assist the indemnifying party in evaluating and in
             defending any such Claims; provided that the indemnifying party
             shall be responsible for the expense associated with any employees
             made available by the indemnified party to the indemnifying party
             hereunder, which expense shall be equal to an amount to be mutually
             agreed upon per person per hour per day for each day or portion
             thereof that such employees are assisting the indemnifying party
             and which expenses shall not exceed the actual cost to the
             indemnified party associated with such employees.

                                      -34-

      (d)    With respect to third party Claims, the indemnified party shall
             make available to the indemnifying party or its representatives on
             a timely basis all documents, records and other materials in the
             possession of the indemnified party, at the expense of the
             indemnifying party, reasonably required by the indemnifying party
             for its use in defending any Claim and shall otherwise cooperate on
             a timely basis with the indemnifying party in the defence of such
             Claim.

      (e)    With respect to any re-assessment for income, corporate, sales,
             excise, or other Taxes or other liability enforceable by
             Encumbrance against the property of the indemnified party, the
             indemnifying party's right to so contest shall only apply after
             such payment of such re-assessment or the provision of such
             security as is necessary to avoid an Encumbrance being placed on
             the property of the indemnified party.

10.5  Exclusion of Other Remedies

No Party shall have the right to bring any proceeding against any other Party
for a breach of any representation, warranty, covenant, or agreement contained

provisions of this Article. This provision is not intended to preclude any
proceeding based on a cause of action or right, including any statutory right,
other than a cause of action in contract or tort for breach of a representation,
warranty, or agreement contained in this Agreement.

the nature in question may fail for technical reasons and accordingly it is
hereby agreed and declared that if any of such restrictions shall be adjudged to
be void as going beyond what is reasonable in all the circumstances for the
protection of the interests of the Purchaser but would be valid if part of the

Mr. Eugene M. Schloss, Jr.
Attorney at Law

Huntingdon Valley, PA 19006 5002

Dear Gene:

Re:   Optopics Laboratories Corporation

Further to our clients' discussions of November 17, 1999 and our discussions of
November 22, 1999, we believe that NutraMax/Optopics and Miza can address the
following outstanding issues cooperatively so as to be in a position to close
the Optopics transaction in an expedient manner and in accordance with the terms
and conditions of the October 15, 1999 Purchase and Sale Agreement (the
"Agreement"). Please note that even though the items set out in paragraphs 2 to
5 below do not all have specific timelines, Miza believes that such items will
be completed on or before December 10, 1999. The items set out in paragraph 1
are, of course, the items which were specifically discussed by the parties and
are of utmost importance to Miza.

1.    The following outstanding regulatory compliance issues in respect of the
      Optopics facility are required to be dealt with by Optopics to Miza's
      reasonable satisfaction prior to closing:

      (a)    The Vitek Jr CC4/DT Computer Upgrade is scheduled as follows:
             - reports are being written: 11/24/99
             - final validation completion date: 11/30/99.

      (b)    The GC (Gas Chromatography) and UV-Vis (Diode Array
             Spectrophotometer)
             - we understand Hewlett Packard is scheduled to complete the
             validation on 12/09/99
             - we understand the equipment will be in compliance when they
             arrive to do the work and will be in compliance when they leave on
             that day.

      (c)    Requalification of the five micro incubators:
             - we understand all protocols have been written
             - we understand validations will be conducted by Mike Morrelli by
             12/03/99.

November 26, 1999
Page Two

      (d)    Media Fill for fill room 1
             - we understand media fill is being run today: 11/24/99.

2.    Installation and testing of the USP Water System:
      - we understand installation of system completed: 11/23/99
      - we understand testing completed: 12/02/99
      - we understand final test results completed: 12/07/99.

3.    The following transition matters need to be completed:

      (a)    Notification of Customers:
             - we understand NutraMax has already communicated with its
             customer base related to the sale of assets, and NutraMax
             would be willing to provide (if feasible) mailing labels to
             Miza if they choose to perform a mailing to the customers.

      (b)    Labels, prints, graphic material
             - we understand the above information is being loaded on a zip
             drive so it can be provided to Miza on the date of closing.

      (c)    The Finished Goods inventory at Gloucester should be
             identified so that Miza can complete its inspection at least a
             day before closing; we understand that our respective clients
             are currently coordinating the process for taking inventory
             and will continue to do so up to closing;

      (d)    Data download:

             The download of all applicable data bases and applications
             necessary to run the Optopics business, including documentation on
             customizations that NutraMax has done to systems including
             Optopics' customer history/data from Symix (or Syteline depending
             on the application that NutraMax is utilizing at closing) to Miza's
             database. The parties have agreed to utilize "Decision Resources"
             (Miza's Symix/Syteline consulting group) to mediate this transfer;
             we understand that Decision Resources will be able to separate the
             Optopics data from the NutraMax data subject to appropriate
             confidentiality obligations in favour of NutraMax;

             - we understand download of all applicable data bases and
             applications will be conducted on the day of closing provided Miza
             has a server in place to receive the data and files. The
             transmission will be done electronically and can be executed upon
             request.

      (e)    Documentation of the current Optopics' customer order processing
             system as handled by NutraMax is required; we understand that this
             work has begun.

4. The following human resources issues need to be finalized:


<PAGE>

November 26, 1999
Page Three


      (a)    All Optopics employees will be terminated effective on closing
             and all required payments shall be made to them by Optopics on
             closing;

      (b)    The distribution of funds for the 401(k) and section 125 plan will
             be made according to the terms of the respective plans and
             applicable law and regulations;

      (c)    All benefits including, but not limited to, medical insurance,
             dental insurance and group life insurance will terminate at
             midnight on the date of termination as per company policy and the
             terms of the respective Plans. Eligible employees will have the
             option COBRA as per applicable law and regulations.

      We understand Dr. Kachkar's consultant, Burt Bartzhoff, is finalizing all
      such matters with Optopics' Carol Woloss in the Human Resources
      Department.

5.    Leased space:

      Optopics is leasing warehouse space in Bridgeton, New Jersey for obsolete
      raw material inventory. As Miza is not purchasing this inventory Optopics
      needs to assign someone to handle its removal from the Bridgeton location.

      - we understand NutraMax intends to remove the product from the leased
      space prior to closing.

We would like to highlight that NutraMax/Optopics have been very helpful and
supportive during this entire process in the interest of an orderly closing of
the transaction. The recent PLMA show in Chicago demonstrated to us that the
NutraMax/Optopics customers and vendors are aware of and supportive of the
transaction. This is of course good news and underscores Miza's commitment to
helping you preserve the business in anticipation of closing.

Miza advises that, to the best of its knowledge, it will be in a position, on or
before closing, to satisfy or comply with the Miscellaneous Provisions imposed
by its banker attached hereto as Exhibit "A".

Subject to the provisions of the Agreement, Miza considers that the foregoing
items constitute an exhaustive list of the issues respecting the contemplated
transaction. It appears therefore that Optopics and Miza will be in a position
to close immediately upon completion of all of the above items. The parties
accordingly agree to amend the Agreement to extend the Closing Date to December
10, 1999. In anticipation of such closing the parties shall hold a pre-closing
on December 9, 1999 at the offices of Ballard Spahr Andrews & Ingersoll, LLP
where all tabled documents shall be held in escrow

BENNETT JONES

                 NUTRAMAX COMPLETES SALE OF OPTOPICS DIVISION

   GLOUCESTER, MA -- NUTRAMAX PRODUCTS, INC. announced today that it has
completed the sale of its Opthalmics Division, Optopics Laboratories, to Miza
Pharmaceuticals, USA. The net proceeds of the sale will be applied to pay down
certain amounts under the Company's credit facility with its senior lenders.

   NutraMax decided early last year to divest the Ophthalmics Division as a
necessary step to improve the financial performance of the Company and to
position NutraMax for future growth in its existing more profitable core areas.

   The sale to Miza satisfies NutraMax's objective to find a buyer that will
continue to service the existing customer base and retain the experienced staff
at Optopics.

   NutraMax is a leading consumer health care products company and the number
one manufacturer and marketer of Store Brand Disposable Douches, ready-to-use
Enemas, Pediatric Electrolyte Oral Maintenance Solutions, Disposable Baby
Bottles, Cough Drops, and Throat Lozenges. The Company also markets a broad line
of Toothbrushes, Dental Floss, and various First Aid Products for the hospital
and industrial safety markets. In addition, the Company offers a broad range of
pharmaceutical manufacturing capabilities to a select group of contract
customers. NutraMax products are sold by supermarkets, drug chains, and mass
merchandisers under both store brand and control brands, including Powers, Sweet
'n Fresh(R), Pure & Gentle, Fresh 'n Easy, Pro Dental, American White Cross, and
NutraMax.
