Item 2. Identity and Background.

        (a) This  Amendment No. 14 amends and  supplements  the Schedule 13D, as
        amended and supplemented by Amendments Nos. 1 through 13, inclusive (the
        "Schedule 13D"), of Moses Marx, an individual,  and Momar Corporation, a
        Maryland corporation  ("Momar"),  with respect to the Common Stock, $.10
        par value  ("Common  Stock")  of  Berkshire  Bancorp  Inc.,  a  Delaware
        corporation  (the  "Company"),  formerly  known as Cooper Life Sciences,
        Inc.  Except  as  amended  hereby,  there  has  been  no  change  in the
        information  contained in the Schedule 13D. Pursuant to Rule 13d-1(f)(1)
        promulgated  under the Securities  Exchange Act of 1934, as amended (the
        "Exchange Act"), this Schedule 13D is being filed by Mr. Marx, Momar and
        Terumah  Foundation,  Inc., a New York  not-for-profit  corporation (the
        "Foundation").   The  individual  and  entities  hereinabove  set  forth
        (collectively,  the "Reporting  Persons") are making this single,  joint
        filing  because they may be deemed to  constitute  a "group"  within the
        meaning of Section 13d(d)(3) of the Exchange Act. Information  regarding
        Mr. Marx, Momar and the Foundation in response to Item 2 of Schedule 13D
        has been previously submitted in prior filings of this Schedule 13D.

Item 5. Interest in Securities of the Issuer.

        (a) - (b)

        According to the Company's  Quarterly Report on Form 10-Q for the period
        ended  September 30, 2005,  there were 6,886,556  shares of Common Stock
        outstanding on November 4, 2005.

        As of the date of this Amendment No. 14, Moses Marx  beneficially  owned
        3,559,693  shares of Common Stock,  representing  51.7%  (calculated  in
        accordance  with the  instructions  to  Schedule  13D) of the issued and
        outstanding  shares of the Common Stock. Said securities  consist of (i)
        2,630,530  shares owned directly by Mr. Marx;  (ii) 285,000 shares owned
        of record by Momar Corporation ("Momar");  (iii) 641,163 shares owned of
        record by the  Foundation;  and (iv) options to purchase 3,000 shares of
        Common Stock.  With respect to the shares  described in clauses (ii) and
        (iii), Mr. Marx may be deemed to be a beneficial owner of such shares by
        virtue of his being the only person (in the case of the  Foundation,  by
        voting together with his wife,  Marga Marx, who together  constitute six
        of the ten votes on the  Foundation's  Board of Directors) in a position
        to  determine  the  investment  and  voting  decisions  of Momar and the
        Foundation, respectively, with respect to such shares.

        The  foregoing  does not include any of the 162,184  shares owned by Eva
        and  Esther,  L.P.,  of which Mr. Marx has a 23.0%  limited  partnership
        interest and of which Mr. Marx's  daughters  and their  husbands are the
        general partners.

        (c) On December 27, 2005, Mr. Marx made a charitable donation of 250,000
        shares of Common Stock to the Foundation. Other than as reported herein,
        the Reporting  Persons  effected no transactions in the shares of Common
        Stock of the Company during the last 60 days.

        (d) Each of the Reporting  Persons affirms that no person other than the
        Reporting  Persons has the right to receive,  or the power to direct the
        receipt of dividends  from, or the proceeds from the sale of, the Common
        Stock owned by the Reporting Persons.

        (e) It is  inapplicable  for the  purposes  hereof  to state the date on
        which the  Reporting  Persons  ceased to be the owners of more than five
        percent of the Common Stock.
