SCHEDULE 13D AMENDMENT No. 5 MAY 9, 2002 ITEM 1. SECURITY AND ISSUER This Schedule 13D relates to the shares of beneficial interest (the "Shares"), of John Hancock Patriot Premium Dividend Fund II (the "Fund"), a Massachusetts business trust registered as an investment company under the Investment Company Act of 1940, as amended (the "Investment Company Act"). The principal executive offices of the Fund are located at 101 Huntington Avenue, Boston, MA, 02119-7603. ITEM 2. IDENTITY AND BACKGROUND (a) - (c) This Schedule 13D is being filed by The Commerce Group Inc. (the "Reporting Person"), a corporation formed under the laws of Massachusetts. The Reporting Person is a corporation whose principal offices are located at 211 Main Street Webster, MA 01570. The name, business address and principal occupation of each director and officer of the Reporting Person are set forth on Annex A hereto, which is incorporated by reference. All information in this Schedule 13D with respect to the persons listed on Annex A is given to the knowledge of the Reporting Person. (d) During the past five years, neither the Reporting Person nor any of the persons listed on Annex A has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). (e) During the past five years, neither the Reporting Person nor any of the persons listed on Annex A has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. (f) All of the individuals listed in Annex A are citizens of the United States. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The source of the funds used by the Reporting Person to purchase Shares listed in Item 5(a) was working capital. The amount of the funds used to purchase such shares aggregated approximately $58,599,515. Page 3 of 12 CUSIP No.: 41013T-10-5 THE COMMERCE GROUP, INC. SCHEDULE 13D AMENDMENT No. 5 MAY 9, 2002 ITEM 4. PURPOSE OF TRANSACTION The shares of beneficial interest of the Fund ("Shares") held by the Reporting Person were acquired in the ordinary course of business by the Reporting Person for the purpose of investment and capital appreciation. In pursuing this investment philosophy, the Reporting Person routinely monitors the performance, trading prices, investment strategy and portfolio securities of the Fund, and of other investment funds in which it invests, and may discuss such matters with fund management, shareholders, or others. The Reporting Person, as an insurance company holding company, is entitled to file securities ownership reports required by the Securities and Exchange Act of 1934 on Schedule 13G. Under amended rules under the Securities Exchange Act of 1934, a person reporting on Schedule 13G may elect to convert such filing to a Schedule 13D, in part, to ensure that discussions with management, or other actions by the Reporting Person, do not limit the Reporting Person's ability to acquire additional Shares, or to vote the shares it already owns. Accordingly, in order to maintain desired flexibility for such transactions and discussions, the Reporting Person elected to convert its ownership filing on Schedule 13G to a filing on Schedule 13D with the filing of its initial Schedule 13D. The matters which the Reporting Person intends to consider, discuss or pursue may include additional purchases of Shares, ceasing the purchase of additional Shares, sales of Shares or one or more of the items described in items (a) through (j) of Item 4 of General Reporting Rules. Whether any of such actions are taken by the Reporting Person will depend upon the Reporting Person's evaluation of several factors, including the Fund's business and prospects, future developments, the level of discount in Share market prices from net asset value ("NAV"), the performance of the Funds' investments, the availability of funds to the Reporting Person, alternative uses of funds, stock and money market conditions, and general economic conditions. Such factors may materially affect the Reporting Person's decision to purchase additional Shares, or take other actions, and may result in the Reporting Person's increasing its ownership to a majority or more of the outstanding Shares, and/or proposing changes in operations, governance or capitalization of the Fund. The Reporting Person will review its investment in the Fund from time to time and reserves the right to take or not take any action it deems to be in its best interest or to change its intention as set forth in this Item 4. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER (a) The Fund's reports with the Securities and Exchange Commission report that 15,002,724 Shares are outstanding. Based upon such number, the Reporting Person beneficially owns 36.1% of the Fund's outstanding Shares. (b) The Reporting Person is the beneficial owner (through its insurance subsidiaries as listed below) of 5,417,800 Shares, over which it has sole power of disposition and voting. Such number of Shares represents approximately 36.1% of the outstanding Shares.

Purchases prior to December 20, 2001 were reported on previous Schedule 13D filings. (d) No person other than the Reporting Person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the shares of Common Stock owned by the Reporting Person. (e) It is inapplicable to state the date on which the Reporting Person ceased to be the beneficial owner of more than five percent of the Common Stock. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER The Reporting Person does not have any contract, arrangement, understanding or relationship (legal or otherwise) with any person with respect to any securities of the Fund, including, but not limited to, the transfer or voting of any such securities, finders' fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
