Item 2. Identity and Background.

(a) This Amendment No. 18 amends and supplements the Schedule 13D, as amended and supplemented by Amendments Nos. 1 through 17, 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 3. Source and Amount of Funds or other Consideration.

The source and amount of the funds used by Mr. Marx to purchase the shares of Common Stock reported in Item 5(c) are personal funds in the aggregate amount of $1,306,973.00.

Item 5. Interest in Securities of the Issuer.

(a) - (b)

According to the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2007, there were 7,054,183 shares of Common Stock outstanding on March 24, 2008.

As of the date of this Amendment No. 18 Moses Marx beneficially owned 3,842,419 shares of Common Stock, representing 54.5% (calculated in accordance with the instructions to Schedule 13D) of the issued and outstanding shares of the Common Stock. Said securities consist of (i) 3,171,256 shares owned directly by Mr. Marx; (ii) 285,000 shares owned of record by Momar; and (iii) 386,163 shares owned of record by the Foundation. 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 a majority of the 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) During the last 60 days, Mr. Marx made the following purchases of shares of Common Stock in open market transactions on the NASDAQ Global Market:

Date	Number of Shares Purchased	Price Per Share
03/13/2008	54,894	$14.75
03/13/2008	15,000	$14.7499
04/04/2008	19,717	$14.00

(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.
