Exhibit 99.1


                      AMERICAN MORTGAGE ACCEPTANCE COMPANY

                AMENDED AND RESTATED INCENTIVE SHARE OPTION PLAN



1.    Purpose
      -------

      The  purpose  of this plan (the  "Plan")  is to permit  American  Mortgage
      Acceptance Company, a Massachusetts business trust (the "Company") and its
      subsidiaries  and its  advisor,  Related  AMI  Associates,  Inc.,  and any
      successor  advisor (the "Advisor") to attract and retain qualified persons
      as trustees,  officers and employees  and to  incentives  and more closely
      align the  financial  interests of the Advisor  with the  interests of the
      Company's  shareholders  by  providing  the  Advisor  with  a  substantial
      financial interest in the Company's success.

      Reference is made to the consent solicitation statement (the "Solicitation
      Statement")  dated  February 11,  1999,  with respect to proposals to make
      certain amendments to the Company's  Declaration of Trust and to adopt the
      Plan as set forth therein.  All  capitalized  terms not otherwise  defined
      herein  shall  have  the  meanings  ascribed  to them in the  Solicitation
      Statement.

      The Plan was amended  and  restated  as set forth  herein  pursuant to the
      Unanimous  Written  Consent of the Board of Trustees of the Company  dated
      April 10, 2003.

2.    Types of Plan Benefits and Administration
      -----------------------------------------

      (a)  Types  of  Awards.  Under  the  Plan,  the  Company  may in its  sole
      discretion  (subject  to the terms of the  Company's  Second  Amended  and
      Restated  Declaration of Trust, as amended from time to time),  grant with
      respect to the Company's shares of beneficial interest, par value $.01 per
      share  ("Shares")  options  ("Options")  to the  trustees,  officers,  and
      employees of the Company or any of its subsidiaries (a  "Subsidiary")  and
      directors,  officers and  employees of the Advisor or any affiliate of the
      Advisor  (the  "Participants"),  as  authorized  by action of the Board of
      Trustees  of the  Company  (or a  committee  designated  by the  Board  of
      Trustees).  As used in the Plan,  an  "Award"  shall mean an Option and an
      "Award Owner" shall mean the owner of an Option.  Options granted pursuant
      to the  Plan  to  Participants  who are  employees  of the  Company  (or a
      Subsidiary)  may be  either  incentive  stock  options  ("Incentive  Stock
      Options")  meeting the requirements of Section 422 of the Internal Revenue
      Code  of  1986,  as  amended  (the  "Code"),   or  non-statutory   options
      ("Non-Statutory Stock Options"),  which are not intended to or do not meet
      the  requirements of Code Section 422. Options granted to Participants who
      are  not  employees  of  the  Company  or  a  Subsidiary   shall  be  only
      Non-Statutory Stock Options.

      (b)  Administration.  The Plan will be  administered by a committee of the
      Board of Trustees of the Company which shall be comprised solely of two or
      more independent  trustees and, if required for compliance with Section 16
      of the Securities  Exchange Act of





      1934 (the "Exchange Act"),  each of whom is a "non-employee  trustee" and,
      if required for compliance  with Section 162(m) of the Code,  each of whom
      is  an  "outside  director"  within  the  meaning  of  such  section  (the
      "Committee").  For  purposes of the Plan, a person shall be deemed to be a
      "non-employee   trustee"   only  if  such  person   would   qualify  as  a
      "non-employee director" within the meaning of Rule 16b-3 of the Securities
      and Exchange  Commission  (the "SEC").  The Committee's  construction  and
      interpretation  of the terms and provisions of the Plan shall be final and
      conclusive.  Subject  to  Section  6(a),  the  Committee  may in its  sole
      discretion  grant Options to purchase Shares to Participants and authorize
      the issuance of Shares upon exercise of such  Options,  as provided in the
      Plan.  The  Committee  shall  have  authority,   subject  to  the  express
      provisions  of the  Plan,  to  construe  the  respective  Award  and Award
      Agreements (as hereinafter defined) and the Plan; to prescribe,  amend and
      rescind rules and regulations relating to the Plan; to determine the terms
      and  provisions  of the  respective  Award  Agreements,  which need not be
      identical;  to advance the lapse of any waiting or installment periods and
      exercise dates and to make all other  determinations  in the sole judgment
      of the  Committee  necessary or desirable  for the  administration  of the
      Plan.  The  Committee  may  correct  any defect or supply any  omission or
      reconcile any inconsistency in the Plan or in any Award or Award Agreement
      in the manner and to the extent it shall deem  expedient to carry the Plan
      into  effect,  and such  determination  shall  be in the  sole  and  final
      judgement of the  Committee.  No trustee,  including  any trustee who is a
      Committee member, shall be liable for any action or determination taken or
      made under or with respect to the Plan or any Award in good faith.

3.    Eligibility
      -----------

      (a)  Generally.  Except as provided in paragraph (b) of this Section 3 and
      Section  6(a) hereof,  Awards  shall be granted  only to the  Participants
      selected  by the  Committee  who  are,  at the  time of  grant,  trustees,
      officers  or  employees  of the  Company or a  Subsidiary  or  officers or
      employees of the Manager. A Participant who has been granted an Award may,
      if he or she is  otherwise  eligible,  be granted  one or more  additional
      Awards if the Committee shall so determine.

      (b)  Incentive  Stock  Options.  No person shall be granted any  Incentive
      Stock Option  under the Plan  unless,  at the time such Option is granted,
      such  person is an employee  of the  Company or any  Subsidiary,  and such
      person  does  not own,  directly  or  indirectly,  Shares  of the  Company
      possessing more than 10% of the total combined voting power of all classes
      of equity  securities  of the  Company or of any  Subsidiary  (unless  the
      requirements of Section 6(g)(i) are satisfied).

4.    Shares Subject to Plan
      ----------------------

      Subject to adjustment as provided in Sections 13 and 14 below, the maximum
      number of Shares that may be issued and sold  pursuant to Options  granted
      under the Plan is ten (10%)  percent  of the  number of Shares  issued and
      outstanding on the date the Proposals are approved.


                                       2



      The Company shall reserve for issuance,  for the purposes of the Plan, out
      of its  authorized  but  unissued  Shares  or out of  Shares  held  in the
      Company's treasury,  or partly out of each, such number of Shares as shall
      be  determined,  from time to time, by the Committee.  If Options  granted
      under the Plan shall expire or  terminate  for any reason  without  having
      been exercised in full, the Shares subject to the unexercised  portions of
      such Options  shall again be available for  subsequent  Award grants under
      the Plan.  Shares  issuable  upon  exercise of Options shall be subject to
      such restrictions on transfer,  repurchase rights or other restrictions as
      may be determined by the Committee.

5.    Form of Award Agreements
      ------------------------

      As a condition to the grant of an Option under the Plan, each recipient of
      an  Option  shall  execute  an  Award   agreement   ("Award   Agreement"),
      substantially  in the form  authorized  by the  Board of  Trustees  of the
      Company or in such other form not  inconsistent  with the Plan as shall be
      specified by the Committee at the time such Option is granted.

6.    Discretionary Grants of Awards to Participants
      ----------------------------------------------

      (a) Initial Restriction on Grant. The Compensation Committee may not grant
      any  options  until six months  after the Shares  have been  listed on the
      American Stock Exchange.

      (b) Share Limitation. Subject to the limitation set forth in Section 4, if
      the   Company's   distributions   per  Share  from  cash   available   for
      distributions  ("CAD") in the immediately  preceding  calendar year exceed
      $1.45 per Share, the Committee will have the authority to issue Options to
      purchase, in the aggregate,  that number of Shares which is equal to three
      (3%)  percent  of  the  Shares  outstanding  as  of  December  31  of  the
      immediately  preceding  calendar year. If the Committee does not grant the
      maximum  number of  Options  in any  year,  the  excess  of the  number of
      authorized  Options which the Committee could have granted over the number
      of  Options  actually  granted in such year will be added to the number of
      Options which the Committee is authorized to grant in the next  succeeding
      year and will be available for grant to  Participants  by the Committee in
      such succeeding  year.  "CAD" shall mean cash available for  distribution,
      which shall consist of the Company's net income (as determined pursuant to
      GAAP) adjusted for certain  non-cash  charges (as  determined  pursuant to
      GAAP).

      (c)  Purchase  Price.  The  purchase  price  per Share  issuable  upon the
      exercise of an Option granted pursuant to this Section 6 shall be the Fair
      Value (as  defined in  Section 16 hereof) on the date that such  Option is
      granted. Notwithstanding anything to the contrary contained herein, in the
      case of an Incentive  Stock Option,  the exercise  price shall not be less
      than  100% of the Fair  Value  of such  stock at the date of grant of such
      Option,  nor  less  than  110% of the Fair  Value  in the case of  Options
      described in Section 6(g)(i).

      (d) Exercise  Period.  Each  discretionary  Award to a  Participant  shall
      expire  on such date as the  Committee  shall  determine,  but in no event
      after the  expiration  of ten (10) years from the date on which such Award
      is  granted,  and in all cases  each  Award  shall be  subject  to earlier
      termination as provided in the Plan or in any Award Agreement.


                                       3



      (e) Vesting of Awards. An Award granted to a Participant may be exercised,
      and payment shall be made upon exercise of such Award,  only to the extent
      that such  Award has  vested.  Awards  shall vest in  accordance  with the
      schedule or terms set forth in the Award  Agreement  executed by the Award
      Owner  and a duly  authorized  Trustee  or  officer  of the  Company.  The
      Committee may  accelerate  the vesting of any Option  granted  pursuant to
      this Section 6.

      (f) Effect of  Termination  of Service.  Upon  termination of service of a
      Participant, all Awards to such Participant to the extent not vested shall
      be  forfeited.  No  Award  may be  exercised  unless,  at the time of such
      exercise,  the Participant is, and continuously since the date of grant of
      his or her Award has been,  engaged by the Company,  a  Subsidiary  or the
      Manager,  as the case may be,  except  that if and to the extent the Award
      agreement or instrument so provides:

            (i) if the  Participant  ceases  to be  engaged  by the  Company,  a
      Subsidiary  or the Manager,  as the case may be, for any reason other than
      death or disability or a discharge for "cause" (as defined in (iv) below),
      the right to exercise the Award,  to the extent  vested,  shall  terminate
      three (3) months after such  cessation (or within such other period as may
      be specified in the Award Agreement or instrument);

            (ii)  if the  Participant  dies  while  engaged  by the  Company  or
      Subsidiary or the Manager or within three (3) months after the Participant
      ceases to be so engaged,  the Awards may be exercised by the administrator
      of the  Participant's  estate,  or by the person to whom the  Options  are
      transferred by will or the laws of descent and distribution, to the extent
      vested,  within  the  period  of one (1) year  after the date of death (or
      within such other  period as may be  specified  in the Award  Agreement or
      instrument);

            (iii) if the  Participant  becomes  disabled  (within the meaning of
      Section  22(e)(3) of the Code) while  engaged by the Company or Subsidiary
      or the Manager, the Awards may be exercised,  to the extent vested, within
      the  period of one (1) year  after the date the  Participant  ceases to be
      engaged  by the  Company  or  Subsidiary  or the  Manager  because of such
      disability,  or within such other  period as may be specified in the Award
      Agreement; and

            (iv) if the  Participant,  prior to the expiration  date of an Award
      ceases his or her services  with the Company or Subsidiary or the Manager,
      as the  case may be,  because  he or she is  discharged  for  "cause"  (as
      defined   below),   the  right  to  exercise  an  Option  shall  terminate
      immediately  upon such  cessation of such  services.  "Cause"  shall mean:
      willful  misconduct in connection  with the  Participant's  performance of
      services for the Company or Subsidiary or the Manager's willful failure to
      perform  his or her  services  in the  best  interest  of the  Company  or
      Subsidiary  or the  Manager,  as the case  may be,  as  determined  by the
      Committee,  which  determination shall be conclusive;  provided,  however,
      that in no event may any Award be exercised  after the expiration  date of
      the Award.  Any Award or portion thereof that is not exercised  during the
      applicable time period specified above (or any shorter period specified in
      the Award Agreement or instrument)  shall be deemed  terminated at the end
      of the applicable time period for purposes of Section 4 hereof.


                                       4



      (g)  Incentive  Stock  Options.  Options  granted  under the Plan that are
      intended to be Incentive Stock Options shall be specifically designated as
      intending  to be  Incentive  Stock  Options  and shall be  subject  to the
      following additional terms and conditions:

            (i) 10%  Shareholder.  If any Participant to whom an Incentive Stock
      Option  is to be  granted  under  the Plan is, at the time of the grant of
      such Option,  the owner of equity  securities  possessing more than 10% of
      the total combined voting power of all classes of equity securities of the
      Company or any Subsidiary,  then the following special provisions shall be
      applicable to the Incentive Stock Option granted to such  individual:  (x)
      the exercise price per Share subject to such Incentive  Stock Option shall
      not be less than 110% of the Fair Value (as  defined in Section 16) of one
      Share at the time of grant;  and (y) the option  exercise period shall not
      exceed five years from the date of grant.

            (ii)  Dollar  Limitation.  Shares of the Company  that are  acquired
      pursuant  to the  exercise  of an  Incentive  Stock  Option  granted  to a
      Participant  under the Plan shall be deemed to be acquired pursuant to the
      exercise of an Incentive  Stock Option under Code Section 422, only to the
      extent that the aggregate Fair Value (determined as of the respective date
      or dates of grant) of the Shares  with  respect  to which  such  Incentive
      Stock Option,  and all other  Incentive  Stock Options that are granted to
      such  Participant  under the Plan (and  under  any other  incentive  stock
      option plans of the Company or any  Subsidiary),  are  exercisable for the
      first time by such  Participant in any one calendar year,  does not exceed
      $100,000. To effectuate the provisions of this Section 6(g), the Committee
      may  designate  the Shares that are  treated as  acquired  pursuant to the
      exercise of an Incentive  Stock  Option by issuing a separate  certificate
      for such Shares and  identifying  such  certificates  as  Incentive  Stock
      Option stock in its stock transfer records.

            (iii) If a Participant  makes a  disposition,  within the meaning of
      Section 424(c) of the Code and regulations promulgated thereunder,  of any
      Share or Shares issued to such Participant  pursuant to the exercise of an
      Incentive  Stock Option within the two-year  period  commencing on the day
      after the date of the grant or within the one-year  period  commencing  on
      the day  after  the  date of  transfer  of such  share  or  shares  to the
      Participant  pursuant to such exercise,  the Participant shall, within ten
      (10) days of such disposition,  notify the Company thereof, by delivery of
      written notice to the Company at its principal executive office.

      Except as modified by the preceding  provisions of this Section 6(g),  all
      the  provisions  of the Plan  applicable to Options shall be applicable to
      Incentive Stock Options granted hereunder.

7.    Method of Exercise
      ------------------

      An Award  Owner may  exercise  an Option  granted  pursuant to the Plan by
      delivering to the Company at its main office  written  notice of exercise,
      which notice shall  specify the number of Shares with respect to which the
      Option is being exercised,  together with payment of the purchase price in
      exchange for the Company's issuance and delivery of certificates therefor.
      The  purchase  price for any Shares  pursuant to the exercise of an Option
      shall be paid in full upon such  exercise by any one or a  combination  of
      the


                                       5



      following: (i) cash (by check), (ii) transferring fully paid Shares to the
      Company with a Fair Value equal to the aggregate  purchase price, or (iii)
      by cash payments in installments or pursuant to a full recourse promissory
      note, in either case, upon such terms as the Committee deems  appropriate.
      Notwithstanding  the  foregoing,  the Committee  shall have  discretion to
      determine  at the time of grant of each Option or at any later date (up to
      and  including  the date of exercise)  the form of payment  acceptable  in
      respect of the exercise of such  Option.  The written  notice  pursuant to
      this  Section 7 may also  provide  instructions  to the Company  that upon
      receipt of the  purchase  price in cash from the Award  Owner's  broker or
      dealer,  designated  as such on the  written  notice,  in payment  for any
      Shares purchased  pursuant to the exercise of an Option, the Company shall
      issue such Shares directly to the designated broker or dealer.  Any Shares
      transferred  to the  Company  as payment of the  purchase  price  under an
      Option shall be valued at their Fair Value on the day  preceding  the date
      of exercise of such Option. If requested by the Committee, the Award Owner
      shall deliver the related Award Agreement to the designated representative
      of the Company who shall  endorse  thereon a notation of such exercise and
      return such agreement to the Award Owner. No fractional Shares (or cash in
      lieu thereof) shall be issued upon exercise of an Option and the number of
      Shares that may be purchased upon exercise shall be rounded to the nearest
      number of whole Shares.

8.    Transferability of Awards
      -------------------------

      No Award granted under the Plan shall be assignable or transferable by the
      Participant to whom it is granted,  either  voluntarily or by operation of
      law,  except by will or the laws of descent and  distribution.  During the
      life of the  Participant,  the Award  shall be  exercisable  only by or on
      behalf of such  person.  Notwithstanding  the  foregoing  and provided the
      Award Owner  receives no  consideration,  the  Committee  may, in its sole
      discretion,  permit  Awards  (other than  Incentive  Stock  Options) to be
      transferable  to (i) a member of the Award Owner's  "immediate  family," a
      trust established by an Award Owner for the benefit of one or more members
      of such Award Owner's  "immediate  family" or a partnership  in which such
      "immediate  family"  members are the only partners or (ii) selected  other
      persons on terms and conditions as determined by the Committee at the time
      of such transfer.  The term  "immediate  family" shall have the meaning of
      such term in Rule 16a-1 of the SEC.;

9.    General Restrictions
      --------------------

      (a) Award Owner Representations.  The Company may require a person to whom
      an Award is granted, as a condition of exercising such Award, to:

            (i) give such written assurances, in substance and form satisfactory
      to the Company,  as the Company deems necessary or appropriate in order to
      comply with  federal and  applicable  state  securities  laws,  including,
      without limitation, that such person is acquiring the Share subject to the
      Award for his or her own account for  investment  and not with any present
      intention of selling or otherwise distributing the same; and

            (ii)  grant to the  Company  the right,  which  shall be for a price
      equal to the Fair Value for such  Shares and upon such other  terms as the
      Committee,  in its sole  discretion,


                                       6



      prescribes,  to repurchase from the Award Owner any or all Shares acquired
      by such Award  Owner  through  the  exercise  of an Award which such Award
      Owner may at any time desire to sell, transfer or otherwise dispose of.

      Certificates  representing  Shares issued upon exercise of the Award shall
      bear such  legends  as are  deemed  appropriate  by legal  counsel  to the
      Company,  unless  the Award  Owner  provides  a written  opinion  of legal
      counsel,  satisfactory  to  the  Company,  that  any  such  legend  is not
      required.

      (b) Compliance With Securities Laws.

            (i) Each Award shall be subject to the  requirement  that, if at any
      time counsel to the Company shall determine that the listing, registration
      or  qualification  of such Award or the Shares  subject to such Award upon
      any securities  exchange or under any state or federal law, or the consent
      or approval of any  governmental  or  regulatory  body,  is necessary as a
      condition of, or in connection with the grant or exercise of such Award or
      the  issuance or purchase  of Shares  thereunder,  such Award shall not be
      effective  or may not be  accepted  or  exercised  in whole or in part (as
      applicable) unless such listing, registration,  qualification,  consent or
      approval shall have been effected or obtained on conditions  acceptable to
      the  Committee.  Nothing  herein shall be deemed to require the Company to
      apply for or to obtain such listing, registration,  qualification, consent
      or approval.

            (ii)  The  Company   shall   provide  each  Award  Owner  with  such
      information,  statements,  discussions  and  analyses  with respect to the
      Company in such manner and at such times as may be required under state or
      federal securities laws.

10.   Rights as a Shareholder
      -----------------------

      The Award Owner shall have no rights as a shareholder  with respect to any
      Shares  covered  by  the  Award  until  the  date  upon  which  the  share
      certificates are issued to him or her for such Shares. Except as otherwise
      expressly  provided  in the  Plan,  no  adjustment  shall be made for cash
      dividends  or other  distributions  or rights for which the record date is
      prior to the date on which such share certificate is issued.

11.   Recapitalization
      ----------------

      In the event that the  outstanding  Shares of the Company are changed into
      or exchanged for a different  number or kind of shares or other securities
      of the Company by reason of any recapitalization,  reclassification, stock
      split,  stock  dividend,  combination or  subdivision,  an appropriate and
      proportionate  adjustment  shall be made in the  number and kind of shares
      subject to the Plan and in the number, kind, and per share exercise price,
      of shares subject to unexercised Options or portions thereof granted prior
      to such adjustment.  Any such adjustment to an outstanding Option shall be
      made  without  change in the total  price  applicable  to the  unexercised
      portion  of  such  Option  as of the  date  of  the  adjustment.  No  such
      adjustment  shall be made with respect to an  Incentive  Stock Option that
      would,  within  the  meaning  of any  applicable  provisions  of the Code,
      constitute a

      modification,  extension or renewal of any Option or a grant of additional
      benefits to the holder of an Option.

12.   Reorganization
      --------------

      In the event that:

            (i) the Company is merged or  consolidated  with  another  entity or
      person other than an Affiliate, and the Company is not a surviving entity,
      or

            (ii) all or substantially  all of the assets or more than 20% of the
      outstanding equity securities of the Company entitled to vote for trustees
      is acquired by any other  entity or person  other than an  Affiliate or an
      entity  or  person  or any  Affiliate  thereof  owning  5% or  more of the
      outstanding voting stock of the Company or

            (iii) there is a reorganization or liquidation of the Company,

      the Committee,  or the board of directors of any corporation  assuming the
      obligations of the Company, shall, as to outstanding Awards, either (x) in
      the case of a merger, consolidation or reorganization of the Company, make
      appropriate provision for the protection of any such outstanding Awards by
      the  substitution  on an equivalent  basis of appropriate  shares or other
      securities  of the Company,  or of the merged,  consolidated  or otherwise
      reorganized  corporation  that will be  issuable  in respect of the Shares
      (provided that no additional benefits shall be conferred upon Award Owners
      as a result of such substitution), or (y) upon written notice to the Award
      Owners,  provide that all  unexercised  Awards must be exercised  within a
      specified  number of days of the date of such  notice  or the  unexercised
      Awards will be terminated, or (z) upon written notice to the Award Owners,
      provide that all  unexercised  Awards shall be purchased by the Company or
      its successor within a specified number of days of the date of such notice
      at a price equal to the value the Award Owners would have received if they
      then exercised all their Awards and  immediately  received full payment in
      respect of such exercise, as determined in good faith by the Committee.

      Notwithstanding  anything  contained in the Plan or any Award Agreement to
      the contrary,  in the event of a  reorganization  or other event described
      above  which is also  intended to  constitute  a Pooling  Transaction  (as
      defined herein),  the Committee shall take such actions, if any, which are
      specifically recommended by an independent accounting firm retained by the
      Company to the extent  reasonably  necessary  in order to assure  that the
      Pooling Transaction will qualify as such, including but not limited to (i)
      deferring the vesting, exercise, payment or settlement with respect to any
      Option,  (ii)  providing  that the payment or settlement in respect of any
      Option be made in the form of cash, Shares or securities of a successor or
      acquirer of the  Company,  or a  combination  of the  foregoing  and (iii)
      providing  for the  extension  of the  term of any  Option  to the  extent
      necessary to accommodate  the  foregoing,  but not beyond the maximum term
      permitted for any Option. For purposes of this Plan, "Pooling Transaction"
      means an acquisition of the Company in a transaction  which is intended to
      be treated as a "pooling of interests" under generally accepted accounting
      principles.

13.   No Special Rights
      -----------------

      Nothing contained in the Plan or in any Award granted under the Plan shall
      confer upon any Award Owner any right with respect to the  continuation of
      his or her service with the Company or Subsidiary or Manager, or interfere
      in any way with the  right of the  Company,  (or any  Subsidiary),  or the
      Manager,  as the  case  may  be,  subject  to the  terms  of any  separate
      agreement to the  contrary,  at any time to  terminate  such service or to
      increase or decrease the  compensation of the Award Owner from the Rate in
      existence  at the time of the grant of an  Award.  Whether  an  authorized
      leave of  absence,  or absence in military or  government  service,  shall
      constitute  termination or cessation of services for purposes of this Plan
      shall be determined by the Committee.

14.   No Special Trustee Rights
      -------------------------

      Nothing contained in the Plan or in any Award granted under the Plan shall
      constitute evidence of any agreement or understanding, express or implied,
      that a trustee  has a right to  continue  as a trustee  for any  period of
      time.

15.   Other Employee Benefits
      -----------------------

      The  amount of any income  deemed to be  received  by an Award  Owner as a
      result of the  exercise  of an Award or the sale of Shares  received  upon
      such  exercise  will not  constitute  "compensation"  or  "earnings"  with
      respect to which any other  benefits of such person are  determined by the
      Company,  including without limitation benefits under any pension,  profit
      sharing, life insurance or salary continuation plan.

16.   Definitions
      -----------

      under common control with, the Company.

      (b) Fair  Value.  The term "Fair  Value" of a Share  shall mean (i) if the
      Shares are traded on a national securities exchange, the closing price for
      such Shares on the day immediately  preceding the date of determination or

      price,  (ii)  if the  Shares  are  not  traded  on a  national  securities
      exchange,  the mean of the  high  bid and ask  quotes  of such  Shares  as

      of the grant of the


                                       9



      Award,  each of the  corporations  other than the last  corporation in the
      unbroken  chain owns stock  possessing  50% or more of the total  combined
      voting power of all classes of stock in one of the other  corporations  in
      such chain.

17.   Amendment of the Plan
      ---------------------

      (a) The Board of Trustees  may at any time and from time to time modify or
      amend the Plan in any respect,  provided that, the Board of Trustees shall
      not modify or amend the Plan without the approval of the  shareholders  of
      the Company if such approval were required or desired for compliance  with
      (i) an  exemption  afforded by Rule 16b-3 or (ii) Section 422 of the Code.
      The  termination or any  modification  or amendment of the Plan shall not,
      without the consent of an Award  Owner,  affect his or her rights under an
      Award  previously  granted  to him or her.  With the  consent of the Award
      Owners affected, the Committee may amend outstanding Award agreements in a
      manner not inconsistent with the Plan.

      (b) Notwithstanding the provisions of Section 17(a), the Board of Trustees
      shall have the right,  but not the obligation,  without the consent of the
      Company's shareholders, to (i) amend or modify the terms and provisions of
      the Plan and of any outstanding  Incentive Stock Options granted under the
      Plan to the extent  necessary  to qualify any or all such options for such
      favorable  federal  income tax treatment  (including  deferral of taxation
      upon exercise),  as may be afforded  incentive stock options under Section
      422 of the Code;  and (ii) amend or modify the terms and provisions of the
      Plan and of any  outstanding  Award  granted  under the Plan to the extent
      necessary to comply with any  securities  law to which,  in the opinion of
      counsel to the Company, the Plan or Award is subject.

18.   Withholding
      -----------

      At such times as an Award Owner  recognizes  taxable  income in connection
      with the receipt of Shares hereunder (a "Taxable Event"),  the Award Owner
      shall pay to the Company an amount equal to the  federal,  state and local
      income taxes and other amounts as may be required by law to be withheld by
      the Company in connection with the Taxable Event (the "Withholding Taxes")
      prior  to the  issuance,  or  release  from  escrow,  of such  Shares.  In
      satisfaction  of the obligation to pay  Withholding  Taxes to the Company,
      the  Committee  may,  in its  discretion  and subject to  compliance  with
      applicable  securities  laws and  regulations,  withhold  Shares having an
      aggregate Fair Value on the date preceding the date of such issuance equal
      to the Withholding Taxes.

19.   Effective Date and Duration of the Plan
      ---------------------------------------

      (a) Effective  Date.  The Plan shall become  effective when adopted by the
      Board of  Trustees,  but no award  granted  under  the Plan  shall  become
      exercisable  unless  and until the Plan shall  have been  approved  by the
      Company's  shareholders  within  twelve months before or after the date of
      such adoption.  If such  shareholder  approval is not obtained within such
      period, any Award previously granted under the Plan shall terminate and no
      further Awards shall be granted. Subject to this limitation, Awards may be
      granted under


                                       10



      the Plan at any time  after the  effective  date and before the date fixed
      for termination of the Plan.

      (b) Termination. The Plan shall terminate upon the earlier of (i) April 5,
      2009, or (ii) the date on which all Shares  available  for issuance  under
      the Plan shall have been issued pursuant to the exercise of Awards granted
      under the Plan. If the date of termination is determined  under (i) above,
      then  Awards  outstanding  on such date shall  continue  to have force and
      effect in accordance  with the  provisions of the  instruments  evidencing
      such Awards.
