                                    Exhibit A

                            THE LEXINGTON CLUB, INC.

                     Amendments to Articles of Organization

         The Articles of Organization of the Corporation, as filed with the
Massachusetts Secretary of State on September 25, 1986, are hereby amended as
follows:

         I.       Article 4 is amended by deleting Article 4 in its entirety and
by substituting in its place and stead the following:

                  The Corporation is authorized to issue 15,000 shares of Common
         Stock, without a par value, and 4,960 shares of Cumulative Preferred
         Stock, having a par value of One Hundred Dollars ($100.00) per share
         (the "preferred stock").

         II.      Article 5 is amended by deleting Article 5 in its entirety and
by substituting in its place and stead the following:

         Cumulative Preferred Stock

                  The holders of the preferred stock shall be entitled to
         receive, when and as declared by the Board of Directors, from funds
         legally available therefor, a cumulative annual dividend equal to
         either (i) ten percent (10%) of the par value of each share of
         preferred stock (the "ordinary dividend rate") or (ii) under the
         circumstances specified below, the special dividend rate as defined
         herein, payable annually on the last business day of each fiscal year
         of the Corporation, before any dividend or other distribution shall be
         declared, set apart or paid on the common stock. Such dividends shall
         accrue on each share of preferred stock from the date of its original
         issue, on a pro rata basis from day to day during each year, regardless
         of whether earned or declared by the Board of Directors. Should the
         legally available funds be insufficient at any time to pay cumulative
         dividends on the preferred stock in whole or in part, such deficiency
         shall be fully paid and set apart for payment from future accumulated
         surplus or net profits until the full amount of all cumulative
         dividends upon the preferred stock shall have been paid or set apart
         for payment before any dividends shall be paid or set apart for payment
         on the Corporation's common stock. If dividends accrue during a year in
         which the special dividend rate applies, such dividends shall be
         payable at such rate regardless of the dividend rate applicable at the
         date of payment.

         Special Dividend Rate

                  In lieu of the ordinary dividend rate on the preferred stock,
         the special dividend rate (as defined below) shall apply with respect
         to any calendar year on the first business day of which the aggregate
         par value of all outstanding preferred stock shall exceed the
         respective values stated below in the years indicated:





                            Aggregate Par Value of
Year                      Outstanding Preferred Stock
- ----                      ---------------------------
                       
1997                               $400,000
1998                                300,000
1999                                200,000
2000                                100,000
2001 and thereafter                     -0-


         The "special dividend rate" shall be a percentage of the par value of
         each share of preferred stock equal to the sum of (x) the "Base Rate",
         "Prime Rate" or other equivalent rate of interest on commercial loans
         in effect on the first business day of the calendar year in question,
         as established by The First National Bank of Boston (or its successor,
         including any bank into which it merges or to which it sells
         substantially all its assets), plus (y) nine percent (9%) per annum.

         Call Feature

                  The preferred stock may be redeemed in whole or in part at any
         time and from time to time at the option of the Board of Directors upon
         not less than 60 days' prior written notice to the holders of record of
         the preferred stock, given in such manner and upon such terms and
         conditions as may be prescribed in the Corporation's by-laws or by a
         resolution duly adopted by the Board of Directors, by payment in cash
         for each share of preferred stock being thereby redeemed equal to $100
         per share (such amount to be adjusted appropriately in the event of any
         stock split, stock combination, or other similar recapitalization
         affecting the preferred stock), in addition to the payment at the time
         of such redemption of all unpaid cumulative dividends accrued on such
         shares to the date of redemption, whether or not earned or declared.

         Voting of Stock

                  The holders of the common stock shall have and exercise all of
         the voting power of the Corporation for the election of directors and
         for all other purposes; provided, however, that so long as any shares
         of preferred stock are outstanding, the Corporation shall not, without
         the prior written consent or the affirmative vote at a meeting called
         for that purpose of the holders of at least two-thirds of the total
         number of shares of preferred stock then outstanding, in any manner,
         whether by amendment to these Articles of Organization or the By-Laws
         of the Corporation or otherwise:

                  (1) Alter or abolish any preferential right, or create, alter
         or abolish any right in respect of redemption of the preferred stock,
         change the par value of or dividend rate on the preferred stock, or
         exclude or limit the right of the preferred stock to vote on a matter
         except as such right may be limited by voting rights given to new
         shares authorized of an existing or new class;



                  (2) Authorize, or increase the authorized amount of, any class
         or series of stock ranking prior to the preferred stock in the payment
         of dividends or the preferential distribution of assets; or

                  (3) Consolidate or merge with, or sell all or substantially
         all of the assets of the Corporation to, any person or entity.

         The holders of the preferred stock shall have no voting power except as
         provided herein or as required under the Massachusetts Business
         Corporation Law.

         Liquidation Distributions

                  In the event of dissolution, liquidation or winding up of the
         Corporation, whether voluntary or involuntary, the holders of the
         preferred stock shall be entitled to receive out of the net assets of
         the Corporation the sum of $100.00 per share (such amount to be
         adjusted appropriately in the event of any stock split, stock
         combination, or other similar recapitalization affecting the preferred
         stock), plus an amount equal to all accrued and unpaid cumulative
         dividends on such shares, whether or not earned or declared, before any
         distribution or payment may be made to, or set aside for, the holders
         of the common stock. If upon the occurrence of any such liquidation,
         dissolution or winding up, the assets and funds to be thus distributed
         among the holders of the preferred stock shall be insufficient to
         permit the payment to such holders of the full aforesaid preferential
         amount, then each issued and outstanding share of preferred stock shall
         entitle the holder thereof to a proportion of the assets and funds to
         be distributed on a pro rata basis, and the holders of the common stock
         shall in no event be entitled to participate in any such distribution
         in respect of their shares. The holders of the preferred stock shall
         not be entitled, in such capacity, to any additional participation in
         the distribution of the net assets of the Corporation beyond the
         participation described in the foregoing sentence.

         Other Rights

                  Except as otherwise provided in these Articles of
         Organization, each share of preferred stock and common stock shall be
         identical in all respects, shall have the same powers, preferences and
         rights, without preference of any such class, series or share over any
         other such class, series or share, and shall be treated as a single
         class of stock for all purposes.



              See test of Amendment attached hereto as Exhibit "A".

         The foregoing amendment will become effective when these articles of
amendment are filed in accordance with Chapter 156B, Section 6 of The General
Laws unless these articles specify, in accordance with the vote adopting the
amendment, a later effective date not more than thirty days after such filing,
in which event the amendment will become effective on such later date.

IN WITNESS WHEREOF AND UNDER THE PENALTIES OF PERJURY, we have hereto signed our
names this 28th day of December, in the year 1990.
