Item 1.  Security and Issuer.

         This  statement on Schedule 13D relates to the common stock, par value
$1.00  per  share  ("Common  Stock"), of Perini  Corporation,  a  Massachusetts
corporation (the "Issuer"), whose principal executive offices are located at 73
Mt. Wayte Avenue, Framingham, MA 01701.

         This  statement  on Schedule  13D is filed by O&G  Industries,  Inc., a
Connecticut corporation (referred to herein as "O&G" or the "Reporting Person").
As described  more fully in Item 4 below,  the  Reporting  Person is filing this
statement  pursuant to Rule 13d-1(a) under the Securities  Exchange Act of 1934,
as  amended,  because it executed  an  agreement  on February 5, 2000 to acquire
2,352,941 shares of Common Stock of the Issuer for a total purchase price of $10
million (the "Securities Purchase Agreement").  If the transactions contemplated
by the Securities Purchase Agreement are consummated,  O&G will beneficially own
11.1% of the Issuer's then-issued and outstanding Common Stock.

         National  Union Fire  Insurance  Company of  Pittsburgh,  PA ("National
Union") and  Tutor-Saliba  Corporation  ("Tutor-Saliba")  have also executed the
Securities  Purchase  Agreement and agreed to acquire an additional  $20 million
and $10 million, respectively, worth of the Issuer's Common Stock. The Reporting
Person disclaims beneficial ownership of the shares of the Issuer's Common Stock
currently  owned,  or to be acquired  in the  transactions  contemplated  by the
Securities Purchase Agreement, by National Union and Tutor-Saliba.

Item 2.  Identity and Background.

         (a)-(c) and (f).  This  statement on Schedule 13D is filed on behalf of
O&G,  which has its  principal  executive  offices  located at 112 Wall  Street,
Torrington,  CT 06790. O&G is a diversified  building materials and construction
services company which is engaged in building general contracting,  construction
management and design/build  services;  heavy  highway/civil  and  environmental
remediation/construction  services;  and the  manufacture  and sale of  building
materials  including  redi-mix concrete,  bituminous paving materials,  quarried
stone, sand and gravel and masonry products.

         The name, business address, principal occupation, address of employment
and citizenship of each executive  officer,  director and controlling  person of
O&G are set forth in Schedule A attached  hereto,  which is hereby  incorporated
herein to this Item 2 by reference.

         (d)  Neither  O&G nor,  to the  best of its  knowledge,  any  executive
officer,  director or controlling  person of O&G named in Schedule A has, during
the last five  years,  been  convicted  in any  criminal  proceeding,  excluding
traffic violations or similar misdemeanors.

         (e)  Neither  O&G nor,  to the  best of its  knowledge,  any  executive
officer,  director or controlling  person of O&G named in Schedule A has, during
the  last  five  years,  been a party to a civil  proceeding  of a  judicial  or
administrative body of competent  jurisdiction as a result of which it 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.

Item 3.  Source and Amount of Funds or other Consideration.

         As of the  date of this  statement,  O&G  owns  150,000  shares  of the
Issuer's Common Stock.  Upon the closing of the Securities  Purchase  Agreement,
O&G will purchase an additional  2,352,941  shares of the Issuer's Common Stock.
The funds to be used for this  purchase  will  consist  solely of O&G's  working
capital.  No  leverage or  borrowed  funds will be used to  purchase  any of the
shares of the Issuer's Common Stock which are the subject of this Schedule 13D.

Item 4.  Purpose of Transaction.

         The Common Stock has been acquired by the Reporting Person for
investment purposes.  Subject to certain restrictions set forth in a
Shareholders Agreement (described  below in Item 6), the Reporting Person may
sell some or all of the Common Stock, either in the open market or in private
transactions  depending on its evaluation of the Issuer's business,  prospects
and financial condition, the market for the Common  Stock, other opportunities
available to the Reporting Person,  prospects for the Reporting  Person's own
businesses, general economic conditions and stock market conditions and further
developments.

         As described below in Item 6, pursuant to the  Shareholders Agreement,
for so long as it maintains  certain  levels of ownership of Common  Stock, O&G
will have the right to nominate one member of the Issuer's  Board of  Directors.
In addition,  National Union, Tutor-Saliba and two of the Exchanging Holders (as
defined  below in Item 6) will  also have the right to  designate  one  director
each.

         Certain other arrangements with respect to corporate  governance of the
Issuer are set forth in the Securities Purchase Agreement,  which is attached as
Exhibit  1 to this  Schedule  13D,  and the  Shareholders  Agreement,  which  is
attached as Exhibit 3 to this Schedule 13D, each of which is incorporated herein
by reference.  Other than as described  above or as set forth in the  Securities
Purchase  Agreement or the Shareholders  Agreement,  the Reporting Person has no
present plans or proposals  that relate to or would result in any of the actions
or  consequences  described in paragraphs (a)-(j) of Item 4 of Schedule 13D, or
any  agreement  regarding  such  matters, although  O&G may in the future  take
actions which would have such consequences.

Item 5.  Interest in Securities of the Issuer.

         (a) As of the date of this  statement,  O&G owns 150,000  shares of the
Issuer's Common Stock.  Upon the Closing of the Securities  Purchase  Agreement,
O&G will own a total of 2,502,941 shares of the Issuer's Common Stock.  Based on
information  contained  in the  Issuer's  Quarterly  Report on Form 10-Q for the
period  ended  September  30, 1999 upon the closing of the  Securities  Purchase
Agreement,  O&G will own approximately  11.1% of the then-issued and outstanding
shares of the Issuer's Common Stock.

         (b) Upon the closing of the  Securities  Purchase Agreement, O&G will
have  the sole  power to vote,  or  direct  the vote of, and the sole power to
dispose,  of or direct the  disposition  of,  2,502,941  shares of the Issuer's
Common Stock.

- --------------------------------------------------------------------------------
         (c) Except as set forth herein,  O&G has not effected any  transactions
in the Issuer's Common Stock during the past sixty (60) days.

         (d) Upon the closing of the  Securities  Purchase  Agreement,  O&G will
have the sole and exclusive right to receive, or the power to direct the receipt
of,  dividends from, or the proceeds from the sale of,  2,502,941  shares of the
Issuer's Common Stock.

         (e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to the Issuer.

         In connection  with the closing of the Securities  Purchase  Agreement,
O&G, Tutor-Saliba, Ronald N. Tutor ("RNT") who serves as the president and chief
executive  officer of  Tutor-Saliba  and who owns or controls 100% of its voting
stock,  National  Union,  and the Issuer will  execute  and become  parties to a
shareholders agreement (the "Shareholders  Agreement") and a registration rights
agreement (the "Registration Rights Agreement").

         The  Shareholders  Agreement will give National Union the right,  under
certain  circumstances,  to put some or all of the  shares it will  purchase  to
Tutor-Saliba  and/or RNT for a price  specified in the  Shareholders  Agreement.
Similarly,   it  will  give  Tutor-Saliba  and  RNT  the  right,  under  certain
circumstances,  to call such shares from National Union for a price specified in
the  Shareholders  Agreement.  The  Shareholders  Agreement  will  prohibit O&G,
Tutor-Saliba, National Union, their transferees, and the holders of the Issuer's
Series B Preferred Stock that are exchanging  their preferred  shares for Common
Stock (the  "Exchanging  Holders") from  transferring any shares of Common Stock
for three years  following the execution of the  Shareholders  Agreement if such
transfer would result in a limitation  being placed on the  deductibility of the
Issuer's net  operating  loss  carryforwards  under  Section 382 of the Internal
Revenue Code. O&G, Tutor-Saliba, National Union, and the Exchanging Holders will
similarly agree to vote their shares against any stock issuance or redemption by
the Issuer if that issuance or redemption  would result in such a limitation and
to use  reasonable  efforts to cause any directors  designated by them to oppose
any such transaction.  The Shareholders Agreement will give each of Tutor-Saliba
and National Union a right of first refusal on  dispositions  of Issuer stock by
each other, and will give O&G, Tutor-Saliba,  National Union, and the Exchanging
Holders rights to sell when any other party to the Shareholders  Agreement sells
shares of the Issuer's Common Stock.

         Lastly,   the  Shareholders   Agreement  will  give  to  each  of  O&G,
Tutor-Saliba,  National  Union,  and two of the Exchanging  Holders the right to
designate  one director  each to be nominated to the board of the Issuer as part
of the management slate. The Issuer will agree to use best efforts to cause such
persons to be  elected  as  directors  and each of O&G,  Tutor-Saliba,  National
Union,  and the  Exchanging  Holders  will agree to vote their  shares of Common
Stock in favor of each others' nominees. These directors may be added to replace
members of the current Board of Directors.  Lastly,  the Shareholders  Agreement
will  give  O&G,  Tutor-Saliba,  National  Union,  and  the  Exchanging  Holders
pre-emptive  rights  with  respect to certain  issuances  of  securities  by the
Issuer.  The Shareholders  Agreement will expire on the sixth anniversary of the
closing of the Securities Purchase Agreement.

- --------------------------------------------------------------------------------


         The  Registration  Rights  Agreement  will grant to O&G,  Tutor-Saliba,
National  Union,   and  the  Exchanging   Holders  certain  shelf,   demand  and
"piggy-back"  registration  rights in respect  of the shares of Issuer  owned by
them immediately following consummation of the Securities Purchase Agreement.

         Except as outlined above in this Item 6, there is no formal  agreement,
written  or oral,  regarding  the  acquisition,  disposition  or  voting  of the
securities  of the Issuer  between the  Reporting  Person and any other  person.
However, O&G anticipates that it may consult with Tutor-Saliba,  National Union,
and/or the Exchanging  Holders with regard to the management and business of the
Issuer from time to time in the future.

Item 7.  Material to be Filed as Exhibits.

         A copy of the  Securities  Purchase  Agreement  is  attached  hereto as
Exhibit  1. A copy  of the  form  of the  Registration  Rights  Agreement  to be
executed in connection with the consummation of the transactions contemplated by
the Securities Purchase Agreement is attached hereto as Exhibit 2. A copy of the
form of the  Shareholders  Agreement  to be  executed  in  connection  with  the
consummation  of  the  transactions  contemplated  by  the  Securities  Purchase
Agreement  is  attached  hereto as  Exhibit 3. Each of  Exhibits  1, 2 and 3 are
incorporated by reference into this Item 7.

               duly organized,  validly  existing and in good standing under the
               laws of The  Commonwealth of  Massachusetts.  The Company is duly
               qualified or licensed and, if applicable,  is in good standing as
               a  foreign  corporation,   in  each  jurisdiction  in  which  the
               properties owned, leased or operated,  or the business conducted,
               by it require such  qualification  or  licensing,  except for any
               such failure so to qualify or be in good standing which would not
               reasonably be expected to have a Material  Adverse  Effect on the
               Company and its  Subsidiaries,  taken as a whole. The Company has
               the requisite  power and authority to carry on its business as it
               is now  being  or is  currently  proposed  to be  conducted.  The

               and Restated By-laws of the Company, dated as of January 17, 1997
               (the   "By-Laws"),   in  each  case  as  amended,   restated  and
               supplemented.

                    (b)  Corporate   Authority.   Subject  to   obtaining   the
               Stockholders Approvals,  each of the Company and its Subsidiaries
               has  (or  will  have  at the  time of  such  act)  the  requisite
               corporate or other power and  authority  to execute,  deliver and
               perform  each  Transaction  Document  to which it is or will be a
               party and to consummate the  transactions  contemplated  thereby.
               The  execution,  delivery  and  performance  of each  Transaction
               Document by the Company  and the  consummation  by the Company of
               the transactions  contemplated  hereby and thereby have been duly
               authorized (or will have been duly authorized at the time of such
               act) by the Board, and no other corporate proceedings on the part
               of  the  Company  are  necessary  to  authorize  any  Transaction
               Document or for the Company to  consummate  the  transactions  so
               contemplated  (other than as  expressly  provided in the terms of
               this Agreement and, with respect to the Issuance, the Stockholder
               Approvals).  Each Transaction Document to which the Company is or
               will be a party is, or when  executed  and  delivered  will be, a
               valid and binding  agreement of such party,  enforceable  against
               the Company in accordance  with the terms thereof,  assuming that
               each  Transaction  Document  to which the Company is a party is a
               valid and binding agreement of the Purchasers (as applicable).

                    (c)  No Violations; Consents and Approvals.

                         (i)  Assuming  that  the   Stockholder   Approvals  are

                    a party or the  consummation  by the  Company  or any of its
                    Subsidiaries of the  transactions  contemplated  thereby (A)

          redeemed or  otherwise  acquired  any shares of its  capital  stock or
          issued any capital stock  (except upon  exercise of options  issued or
          agreed to be issued  prior to the date  hereof  under a Company  Stock

          regulations  of the SEC as of the  date of such  report  and as of the
          date of this Agreement.  Each Subsidiary has been duly incorporated or
          organized  and is validly  existing  as a  corporation  or other legal

          incorporation  or  formation,  has the  corporate  or other  power and
          authority to own,  lease and operate its assets and  properties and to

          assets or property requires such qualification, other than any failure
          to be so  qualified  or in good  standing as would not  reasonably  be
          expected  to have a Material  Adverse  Effect on the  Company  and its
          Subsidiaries,  taken as a whole. All of the outstanding  capital stock
          of each  Subsidiary has been duly  authorized and validly  issued,  is

          stock,  any  additional  capital stock or any other  securities of any
          Subsidiary.

          schedules,  forms, statements and other documents required to be filed
          by it with the SEC under the Securities Act and the Exchange Act since
          January  1, 1993 and up to the date  hereof  and it will file all such
          documents  required to be filed before the Closing (the "Filed Company
          SEC  Documents").  As of its  filing  date,  each  Filed  Company  SEC
          Document  filed,  as  amended  or  supplemented,  if  applicable,  (i)
          complied  in all  respects  with the  applicable  requirements  of the
          Securities Act or the Exchange Act, as  applicable,  and the rules and
          regulations  thereunder  and (ii) did not,  at the time it was  filed,
          contain any untrue  statement of a material  fact or omit to state any
          material fact  required to be stated  therein or necessary to make the
          statements  therein,  in light of the  circumstances  under which they
          were made, not misleading.

               (g)  Financial  Statements.  Each of the  consolidated  financial

          complied  as  to  form  in  all  material   respects  with  applicable
          accounting requirements and the published rules and regulations of the
          SEC with respect  thereto,  (ii) was prepared in accordance  with GAAP
          applied on a consistent basis throughout the periods indicated (except

          the case of unaudited statements, as permitted by the SEC on Form 10-Q
          under the Exchange Act) and (iii) fairly  presented  the  consolidated
          financial  position  of the  Company  and its  Subsidiaries  as of the
          respective  dates  thereof  and  the   consolidated   results  of  its
          operations,  stockholders' equity and cash flows, in each case for the
          respective periods indicated, consistent with the books and records of
          the Company and its  Subsidiaries,  except that the unaudited  interim
          financial  statements are subject to normal year-end adjustments which
          are not expected to be material in amount. The unaudited balance sheet
          of the Company as of  September  30, 1999 is referred to herein as the
          "Balance Sheet."

               (h) Undisclosed Liabilities. Except (i) as disclosed in the Filed
          Company SEC  Documents or in any Section of the  Disclosure  Schedule,
          and,  in either  case,  reserved  for in the Balance  Sheet,  and (ii)
          normal  and  recurring  liabilities  incurred  since  the  date of the
          Balance Sheet in the ordinary course of business consistent with prior
          practices and not prohibited by the Transaction Documents, the Company
          and its Subsidiaries do not have any liabilities or obligations or any
          nature,   whether  known  or  unknown,   whether  absolute,   accrued,
          contingent or otherwise, and whether due or to become due, which would
          reasonably  be  expected  to have a  Material  Adverse  Effect  on the
          Company and the Subsidiaries, taken as a whole.

               (i) Absence of Certain  Events and  Changes.  Except as otherwise
          contemplated by the Transaction Documents,  since January 1, 1999, the
          Company and its  Subsidiaries  have  conducted  their  business in the
          ordinary  course,  consistent with past  practices,  and there has not
          been any  event,  change or  development  which  would  reasonably  be
          expected  to have a Material  Adverse  Effect on the  Company  and its
          Subsidiaries, taken as a whole.

               (j) Compliance with Applicable  Laws. Each of the Company and its
          Subsidiaries  is in compliance with all statutes,  laws,  regulations,
          rules,  judgments,  orders and  decrees of all  Governmental  Entities
          applicable to it, and neither the Company nor any of the  Subsidiaries
          has received any notice alleging  noncompliance except, with reference
          to all the foregoing,  where the failure to be in compliance would not
          reasonably  be  expected  to have a  Material  Adverse  Effect  on the
          Company and its  Subsidiaries,  taken as a whole.  Each of the Company
          and its  Subsidiaries  has all Permits  that are  required in order to
          permit  it to  carry on its  business  as it is  presently  conducted,
          except where the failure to have such Permits would not  reasonably be
          expected  to have a Material  Adverse  Effect on the  Company  and its
          Subsidiaries, taken as a whole. All such Permits are in full force and
          effect and the Company and its Subsidiaries are in compliance with the
          terms of such  Permits,  except  where the failure to be in full force
          and effect or in compliance would not reasonably be expected to have a
          Material Adverse Effect on the Company and its Subsidiaries,  taken as
          a whole.  This Section  3.01(j)  does not relate to employee  benefits
          matters  (for  which  Section  3.01(o) is  applicable),  environmental
          matters (for which Section  3.01(p) is applicable) or tax matters (for
          which Section 3.01(n) is applicable).

               (k) Title to Assets.  The Company and the Subsidiaries have title
          to all material  properties  (real and personal)  owned by the Company
          and the  Subsidiaries  which  are  necessary  for the  conduct  of the
          business of the Company and the Subsidiaries as described in the Filed
          Company SEC  Documents and as currently  conducted,  free and clear of
          any Lien that would  reasonably be expected to have a Material Adverse
          Effect on the Company and its  Subsidiaries,  taken as a whole. To the
          Company's  Knowledge,  all material properties held under lease by the
          Company or the  Subsidiaries  are held  under  valid,  subsisting  and
          enforceable   leases.   This  Section   3.01(k)  does  not  relate  to
          Intellectual Property (for which Section 3.01(s) is applicable).

               (l) Litigation.  There are no civil,  criminal or  administrative
          actions,  suits or  proceedings  pending or, to the  Knowledge  of the
          Company,  threatened,  against the Company or any of its  Subsidiaries
          that, if adversely determined,  would reasonably be expected to have a
          Material Adverse Effect on the Company and its Subsidiaries,  taken as
          a whole.  There are no  outstanding  judgments,  orders,  decrees,  or
          injunctions of any  Governmental  Entity against the Company or any of
          its Subsidiaries that, would be reasonably expected to have a Material
          Adverse Effect on the Company and its Subsidiaries, taken as a whole.

               (m) Contracts.  All of the Company's  Contracts that are required
          to be described in the Filed  Company SEC  Documents or to be filed as
          exhibits  thereto are  described in the Filed Company SEC Documents or
          filed as exhibits  thereto and are legal,  valid,  binding and in full
          force  and  effect  except  to  the  extent  that  any  failure  to be
          enforceable  would  not  reasonably  be  expected  to have a  Material
          Adverse Effect on the Company and its Subsidiaries,  taken as a whole.
          There does not exist under any Contract any violation, breach or event
          of default,  or event or condition that, after notice or lapse of time
          or both,  would  constitute  a  violation,  breach or event of default
          thereunder,  on the part of the Company or any of the Subsidiaries or,
          to the  Knowledge of the Company,  any other  Person,  other than such
          violations,  breaches or events of default as would not  reasonably be
          expected  to have a Material  Adverse  Effect on the  Company  and its
          Subsidiaries,  taken as a whole. The  enforceability  of all Contracts
          will not be  affected  in any  manner by the  execution,  delivery  or
          performance of any of the Transaction Documents or the consummation of
          the transactions  contemplated  thereby,  and no Contract contains any
          change in  control  or other  terms or  conditions  that  will  become
          applicable  or  inapplicable  as a result of the  consummation  of the
          transactions contemplated hereby or thereby except for such effects as
          would not reasonably be expected to have a Material  Adverse Effect on
          the Company and its Subsidiaries, taken as a whole.

          its Subsidiaries (the "Owned Intellectual  Property")  constitutes all
          of the Intellectual Property used, intended to be used or held for use
          in  connection  with,  necessary  for the  conduct  of,  or  otherwise
          material to the Company and the Subsidiaries,  except for Intellectual
          Property   subject  to  written  or  oral   licenses,   agreements  or
          arrangements pursuant to which the use of Intellectual Property by any
          Company  or  any   Subsidiary   is   permitted   by  any  Person  (the
          "Intellectual   Property   Licenses"  and,  together  with  the  Owned
          Intellectual Property, the "Company Intellectual Property"). The Owned
          Intellectual  Property  is owned  free  from  any  Liens  (other  than

          Closing,  the Company and the Subsidiaries  will own or have the right
          to use all the Company Intellectual  Property,  in each case free from
          Liens (except for Permitted  Liens incurred in the ordinary  course of
          business)  and on the same terms and  conditions as in effect prior to

          To the  Knowledge  of the  Company,  none of the Company  Intellectual
          Property is being  infringed by any third party.  There is no claim or
          demand of any Person pertaining to, or any proceeding which is pending
          or, to the Knowledge of the Company,  threatened,  that challenges the
          rights of the  Company  or any of the  Subsidiaries  in respect of any
          Company Intellectual  Property, or that claims that any default exists
          under  any  Intellectual   Property  License.   None  of  the  Company
          Intellectual  Property is subject to any  outstanding  order,  ruling,
          decree,  judgment  or  stipulation  by or with  any  court,  tribunal,
          arbitrator, or other Governmental Entity adverse to the Company.

          with,  filed in or  issued  by,  as the case may be,  the  appropriate
          filing  offices,  domestic  or  foreign,  to the extent  necessary  or
          desirable to ensure usual and customary  protection  for  Intellectual
          Property in the relevant  jurisdiction  under any applicable  law, and
          the  same  remain  in full  force  and  effect.  The  Company  and the
          Subsidiaries  have taken all  necessary  actions  to ensure  usual and
          customary  protection  in the  relevant  jurisdiction  of the  Company
          Intellectual  Property  (including  maintaining  the  secrecy  of  all
          confidential  Intellectual  Property)  under any applicable law or any
          Contract.

          (t) Guarantees.  Section 3.01(t) of the Disclosure Schedule sets forth
     a description  of any  obligations  or liabilities of any person other than

                    a whole.

                         (iv) The Company and each  Subsidiary  has given notice

     SECTION 5.04 [Intentionally Omitted]

     SECTION 5.05 Stockholder Approvals; Proxy Statement.

          (a)  The  Company  shall  call  a  meeting  of its  stockholders  (the
     "Stockholder   Meeting")  for  the  purpose,  among  others,  of  obtaining
     stockholder approvals for: (i) an amendment to the Articles of Organization
     increasing  the number of authorized  shares of Common Stock to at least as
     many shares of Common Stock as are necessary to consummate the  transaction
     contemplated  hereby and (ii) the issuance and sale (the "Issuance") of the
     Shares to Purchasers  and the exchange of the Series B Preferred  Stock for
     shares of Common Stock as contemplated by Section 6.03(c) (the "Stockholder
     Meeting  Proposals").  The  Stockholder  Meeting  shall  be held as soon as
     practicable  but in no event later than the Outside  Date.  For purposes of
     this Agreement,  "Stockholder  Approvals" shall mean, as to clause (i), the
     affirmative  vote of the  holders of a majority of the shares of the Equity
     Securities entitled to vote thereon and, as to clause (ii), the affirmative
     vote of the holders of a  Disinterested  Majority of the Equity  Securities
     entitled to vote thereon. Where so required by applicable Massachusetts law
     or the  Articles  of  Organization,  Stockholder  Approvals  shall mean the
     separate vote of each class of stock entitled to vote thereon.

          (b) The Company will  prepare and file with the SEC a proxy  statement
     relating  to the  Stockholder  Meeting  (as  amended  or  supplemented  and
     including   documents   incorporated  by  reference  therein,   the  "Proxy
     Statement")  and shall use its  reasonable  best  efforts to respond to any
     comments  of the SEC or its staff and to cause  the Proxy  Statement  to be
     cleared by the SEC. The Company  shall notify  Purchasers of the receipt of
     any comments from the SEC or its staff and of any request by the SEC or its
     staff  for  amendments  or  supplements  to  the  Proxy  Statement  or  for
     additional  information and shall supply  Purchasers and their counsel with
     copies  of  all   correspondence   between   the  Company  or  any  of  its
     representatives,  on the one hand,  and the SEC or its staff,  on the other
     hand,  with  respect  to  the  Proxy  Statement.  The  Company  shall  give
     Purchasers and their counsel the  opportunity to review the Proxy Statement
     prior to its being filed with the SEC and shall give  Purchasers  and their
     counsel the  opportunity to review all  amendments  and  supplements to the
     Proxy  Statement and all responses to requests for  additional  information
     and  replies to comments  prior to their being filed with,  or sent to, the
     SEC.  Each of the  Company and  Purchasers  agrees to use  reasonable  best
     efforts,  after  consultation  with the  other  party  hereto,  to  respond
     promptly to all such  comments of and requests by the SEC.  After the Proxy
     Statement  has been  cleared by the SEC,  the Company  shall mail the Proxy
     Statement to the  stockholders of the Company.  If at any time prior to the
     Stockholder Meeting there shall occur any event that should be set forth in
     an amendment or supplement to the Proxy Statement, the Company will prepare
     and mail to its stockholders such an amendment or supplement.

          (c) The Proxy  Statement will not, at the date mailed to the Company's
     stockholders and at the date of the Stockholder Meeting, contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary in order to make the statements  therein, in
     light of the circumstances  under which they are made, not misleading.  The
     Proxy  Statement  will comply as to form in all material  respects with the
     provisions  of the Exchange Act and the rules and  regulations  thereunder,
     except  that no  representation  is made by the  Company  with  respect  to
     statements  made therein as to information  concerning  Purchasers or their
     Affiliates  supplied in writing by  Purchasers  or any of their  Affiliates
     specifically for inclusion in the Proxy Statement.

          (d) Unless this Agreement has been  terminated (i) pursuant to Section
     7.01(d)(ii)  (based  upon a failure of the  condition  set forth in Section
     6.02(d)), or (ii) pursuant to Section 7.01(d)(iii) based upon the existence
     of a Superior  Transaction  Proposal that the Board intends to accept,  the
     Board  and  the  Special  Committee  shall  recommend  that  the  Company's
     stockholders  approve the  Stockholder  Meeting  Proposals  and the Company
     shall  use its best  efforts  to  obtain  the  necessary  approvals  by its
     stockholders of the Stockholder Meeting Proposals.

     SECTION 5.06 Stock Exchange Listing. The Company shall use its commercially
reasonable efforts to cause Purchasers to receive,  prior to Closing,  assurance
from  the  American  Stock  Exchange  (the  "Exchange"),  in a  form  reasonably
satisfactory  to the  Purchasers,  that: (a) in accordance with the rules of the
Exchange,  all Shares will be  eligible  for  listing on the  Exchange;  and (b)
consummation of the transactions contemplated herein or in any other Transaction
Document  will not cause any  securities  of the Company  already  listed on the
American Stock Exchange to lose their listing privileges.

     SECTION 5.07 Transaction Proposals.

          (a) For purposes of this Agreement,  "Transaction  Proposal" means any
     inquiry,  proposal or offer from any Person (other than a Person that is an
     Affiliate  of  the  Purchasers)  relating  to (i)  any  purchase  or  other
     acquisition from the Company of assets  representing 20% or more of the net
     revenues, net income or profits of the Company and its Subsidiaries,  taken
     as a  whole,  (ii)  any  purchase  or  other  acquisition  of any  class of
     securities of the Company for a purchase price in excess of $20 million, or
     (iii) any merger,  consolidation,  business combination,  recapitalization,
     liquidation,  dissolution or similar transaction  involving the Company (or
     any subsidiary whose business  constitutes 20% or more of the net revenues,
     net  income or  assets  of the  Company  and its  subsidiaries,  taken as a
     whole). For purposes of this Section 5.07, separate  Transaction  Proposals
     by  Affiliates  or by  Persons  in a  "group"  (as  defined  in  the  rules
     promulgated  under  Section 13 of the  Exchange  Act),  as well as separate
     Transaction  Proposals that are adopted by the Company as part of a plan of
     financing or capitalizing  the Company shall be aggregated and treated as a
     single  proposal  for  purposes of  determining  whether  such  proposal or
     proposals exceed the thresholds set forth in this Section 5.07(a).

          (b) At  least  ten  (10)  days  prior  to  either  (x)  accepting  any
     Transaction  Proposal  or (y)  any  change  by  the  Board  or the  Special
     Committee in their  respective  recommendations  concerning the Stockholder
     Meeting  Proposals (if following the receipt of any Transaction  Proposal),
     the  Company  shall  advise  Purchasers  orally  and  in  writing  of  such
     Transaction  Proposal  and  the  material  terms  and  conditions  of  such
     Transaction  Proposal  and the  identity  of the  Person  making  any  such
     Transaction  Proposal.  During  such  ten day  period,  the  Company  shall
     negotiate in good faith to determine whether  Purchasers can or are willing
     to make a proposal that is superior to the Transaction Proposal. Subject to
     complying  with the foregoing  provisions of this Section 5.07, the Special
     Committee and its representatives and advisors on behalf of the Company may
     solicit  Transaction  Proposals and furnish or cause the Company to furnish
     information  with respect to the Company and its Subsidiaries to any Person
     and  may   participate  in  discussions  or   negotiations   regarding  any
     Transaction Proposal.

     copies therefrom),  and to consult with respect to and discuss the affairs,
     businesses,  finances,  operations  and  accounts  of the  Company  and the
     Subsidiaries with the officers, directors, employees, affiliates and agents

     may reasonably request.

     sold to it onI the Closing Date, the Company will deliver to such Purchaser
     the following:

               (i) As soon as practicable  and in any event within 45 days after

     prior to disclosing any  information  pursuant to this Section  5.09(a),  a
     Purchaser shall, if reasonably possible,  give prior written notice thereof
     to the Company and provide the Company with the opportunity to contest such
     disclosure.

          (b)  Publicity.  Prior to Closing,  the Company  and  Purchasers  will

     any time prior to the Closing Date, were directors,  officers, employees or
     agents of Company with respect to claims  arising from facts or events that
     occurred at or prior to the Closing.

          (b) Prior to the Closing, the Company shall have offered each director

     least the same coverage and amounts  containing  terms and conditions which
     are not materially  less  advantageous  with respect to claims arising from
     facts or events which occurred at or before the Closing;  provided further,
     however,  that,  in no event shall the Company be required to expend in any
     one year in  excess of 125% of the  annual  premium  currently  paid by the
     Company for such coverage, which current premium amount is set forth on the
     Disclosure  Schedule  and if the premium  for such  coverage  exceeds  such
     amount,  the Company  shall  purchase a policy with the  greatest  coverage
     available for such 125% of the annual premium.

     merger or (ii)  transfers all or  substantially  all of its  properties and
     assets to any Person, then and in each such case, proper provision shall be
     made  so  that  the  successors  and  assigns  of the  Company  assume  the
     obligations set forth in this Section 5.12.

          (e) The foregoing  provisions of Section 5.12 are  obligations  of the

          to this clause (i) shall not be available  to any party whose  failure

          terms of this Agreement; or

               (ii) if the Board or any committee  thereof withdraws or modifies
          (or publicly  announces  its intention to do so, or resolves to do so)
          in a manner  adverse to Purchasers  (as determined by any Purchaser in

          herein qualified by materiality or shall have breached in any material
          respect  any   representation  or  warranty  not  so  qualified,   and
          Purchasers have failed to perform such obligation or cure such breach,

          the following  conditions  have been met: (x) the Company has complied
          with the  terms of  Section  5.07,  (y) the  Company  has  received  a

          Committee  determines in good faith,  after  consultation with outside
          counsel,  that it is  advisable  to do so in order to comply  with its
          fiduciary duties to the Company's stockholders under applicable law.

Agreement by either the Company or any  Purchaser  as provided in Section  7.01,

of this Article VII, the exercise by any one Purchaser of its termination rights
under Section 7.01 shall relieve such  Purchaser of all  obligations  under this
Agreement (other than those set forth in this Section 7.03,  Section 5.09(a) and
Section  9.08) but shall not result in the  termination  of this  Agreement  if,

Purchasers,  one or more of the other  Purchasers shall agree to an amendment to
Exhibit 2.01  pursuant to which all Shares  proposed to be purchased  under this
Agreement  are  purchased  by the other  Purchasers  (and provide a copy of such
amended Exhibit 2.01 to the Company).

agrees to defend,  indemnify  and hold harmless  each of the  Purchasers,  their
Affiliates  (other  than the  Company  and any of its  Subsidiaries),  and their
respective  officers,  directors,  partners,  employees,  agents,  advisers  and
representatives  (collectively,  the "Purchaser  Indemnitees") from and against,
and pay or reimburse the Purchaser  Indemnitees  for, any and all  Indemnifiable
Losses resulting from or based on (or allegedly resulting from or based on):

          (a) any  litigation or claims  (including by any  stockholders  of the
     Company in connection  with any derivative  actions,  but not including any
     litigation or claims  brought or made by any of the  Purchaser  Indemnitees
     under this clause (a)) resulting  from or based on (or allegedly  resulting
     from or based on) any of the  transactions  contemplated by the Transaction
     Documents,  provided that the  indemnity  provided in this clause (a) shall
     not include (i) losses  resulting from or based on the acts or omissions of
     Purchaser  Indemnitees following the Closing, or (ii) claims resulting from
     or  based  on a  breach  by  any  of the  Purchasers  of  its  obligations,
     representations,  warranties, agreements or covenants under this Agreement;
     or (iii) claims resulting from any contract,  obligation or other agreement
     between a third party claimant (other than a stockholder, whether common or
     preferred,  bondholder,  lender,  director or officer of the Company (or an
     Affiliate of any of the foregoing)) and any Purchaser;  provided,  however,
     that in no such case shall this  Section  8.01(a) be construed to limit the
     indemnity  rights  that a  Purchaser  Indemnitee  may  have  in  any  other
     Transaction Document; or

          (b)  any  breach  by  the  Company  of any  representation,  warranty,
     covenant  or  obligation  of the  Company  hereunder  or  under  any  other
     Transaction Document.

The Company shall  reimburse the  Purchaser  Indemnitees  for any legal or other
expenses incurred by such Purchaser Indemnitees in connection with investigating
or  defending  any such  Indemnifiable  Losses as such  expenses  are  incurred.
Notwithstanding the foregoing provisions of this Section 8.01, the Company shall
not be liable to a Purchaser  Indemnitee in any such case to the extent that any
such loss, claim, damage,  liability or action arises out of or is based upon an
untrue statement or omission made in the Proxy Statement,  or any such amendment
or  supplement,  in reliance  upon and in  conformity  with written  information
furnished  to the  Company by such  Purchaser  Indemnitee  (or its  Affiliates),
specifically for use in the preparation thereof.

     SECTION  8.02  Indemnification  Procedures.  Promptly  after  receipt  by a
Purchaser  Indemnitee of notice of the commencement of any action or the written
assertion of any claim,  such Purchaser  Indemnitee shall, if a claim in respect
thereof is to be made against the Company, as the case may be (the "Indemnifying
Person"),  notify the Indemnifying  Person in writing of the commencement or the
written assertion  thereof.  Failure by a Purchaser  Indemnitee to so notify the
Indemnifying Person shall relieve the Indemnifying Person from the obligation to
indemnify such  Purchaser  Indemnitee  only to the extent that the  Indemnifying
Person suffers actual and material  prejudice as a result of such failure but in
no event shall such  failure to notify the  Indemnifying  Person (i)  constitute
prejudice  suffered  by the  Indemnifying  Person if it has  otherwise  received
notice of the  actions  giving  rise to such  obligation  to  indemnify  or (ii)
relieve it from any liability or obligation  that it may otherwise  have to such
Purchaser  Indemnitee  under this  Agreement.  In case any such  action or claim
shall be brought or  asserted  against  any  Purchaser  Indemnitee  and it shall
notify the  Indemnifying  Person of the commencement or assertion  thereof,  the
Indemnifying  Person shall be entitled to participate therein but the defense of
such action or claim shall be conducted by counsel to the Purchaser  Indemnitee,
provided,  however,  that the Indemnifying  Person shall not, in connection with
any one such action or proceeding or separate but substantially  similar actions
or proceedings  arising out of the same general  allegations,  be liable for the
fees and  expenses of more than one  separate  firm of attorneys at any time for
all Purchaser Indemnitees,  except to the extent that local counsel, in addition
to regular  counsel,  is required in order to  effectively  defend  against such
action or proceeding and provided further that a Purchaser  Indemnitee shall not
enter into any  settlement  of any such claim  without the prior  consent of the
Company, such consent not to be unreasonably withheld or delayed.

     SECTION 8.03 Survival of Representations,  Warranties and Covenants. Except
as  provided  in  clauses   (a),  (b)  or  (c)  of  this   Section   8.03,   the
representations,   warranties,   covenants,  and  agreements  included  in  this
Agreement shall survive for a period of three (3) years: (a) the obligations set
forth in Sections 5.08 (Access and  Information),  5.09(b)  (Publicity) and 5.12
(Directors' and Officers' Indemnification and Insurance),  shall survive for the
periods  specified  therein  for the  performance  of the  covenants  set  forth
therein; (b) the representations set forth in Sections 3.01(n) (Taxes),  3.01(o)
(Employee Benefit Plans and Related Matters;  ERISA) and 3.01(p)  (Environmental
Laws) shall survive  until the date that is six (6) months after the  expiration
of the longest applicable  federal or state statute of limitations;  and (c) the
obligations  set  forth  in  Sections   5.09(a)   (Confidentiality),   and  5.10
(Restrictions), and Articles VIII (Indemnification) and IX (Miscellaneous) shall
survive indefinitely.

                                   ARTICLE IX

                                  Miscellaneous

     SECTION 9.01 Severability.  If any term, provision, covenant or restriction
of this  Agreement is held by a court of competent  jurisdiction  to be invalid,
void or  unenforceable,  the remainder of the terms,  provisions,  covenants and
restrictions  of this Agreement  shall remain in full force and effect and shall
in no way be affected,  impaired or  invalidated.  It is hereby  stipulated  and
declared to be the  intention of the parties  that they would have  executed the
remaining terms, provisions, covenants and restrictions without including any of
such which may be hereafter declared invalid, void or unenforceable.

     SECTION 9.02 Specific  Enforcement.  Purchasers,  on the one hand,  and the
Company, on the other, acknowledge and agree that irreparable damage would occur
in the event that any of the  provisions of this Agreement were not performed in
accordance  with  their  specific  terms  or  were  otherwise  breached.  It  is
accordingly  agreed that the  parties  shall be  entitled  to an  injunction  or
injunctions  to prevent  breaches of the  provisions  of this  Agreement  and to
enforce  specifically the terms and provisions hereof in any court of the United
States or any state thereof having  jurisdiction,  this being in addition to any
other remedy to which they may be entitled at law or equity.

     SECTION 9.03 Entire Agreement.  This Agreement  (including the Exhibits and
Schedules  hereto)  and the  other  Transaction  Documents  contain  the  entire
understanding  of the  parties  with  respect to the  transactions  contemplated
hereby.

     SECTION 9.04  Counterparts.  This  Agreement may be executed in one or more
counterparts,  all of which shall be considered one and the same agreement,  and
shall become effective when one or more of the counterparts  have been signed by
each party and  delivered to the other  parties,  it being  understood  that all
parties need not sign the same counterpart.

     SECTION  9.05  Notices.  All  notices,  consents,  requests,  instructions,
approvals and other communications  provided for herein and all legal process in
regard  hereto  shall be  validly  given,  made or  served,  if in  writing  and
delivered  personally,  by  telecopy  (except  for  legal  process)  or  sent by
registered mail, postage prepaid, if to:

     SECTION 9.06 Amendments. This Agreement may be amended as to Purchasers and
their  successors and assigns  (determined as provided in Section 9.07), and the
Company  may take any  action  herein  prohibited,  or omit to  perform  any act
required to be performed by it, if the Company shall obtain the written  consent
of  Purchasers.  This  Agreement  may  not  be  waived,  changed,  modified,  or
discharged  orally,  but only by an agreement in writing  signed by the party or
parties  against  whom  enforcement  of  any  waiver,  change,  modification  or
discharge  is sought or by parties  with the right to  consent  to such  waiver,
change, modification or discharge on behalf of such party.

     SECTION 9.07 Successors and Assigns. All covenants and agreements contained
herein  shall  bind and inure to the  benefit  of the  parties  hereto and their
respective successors and assigns. Prior to the Closing Date, National Union may
assign all of its rights and obligations to American  International  Group, Inc.
("AIG") or any other person the equity of which is, directly or indirectly, 100%
owned by AIG, without the consent of the other parties hereto, and may assign up
to 50% of the  interest to be acquired  by it  pursuant to this  Agreement  to a
third party,  subject to the written consent of the Company and TSC, which shall
not be  unreasonably  withheld  (and, in either such event,  such assignee shall
become a "Purchaser"  hereunder).  Except as provided in the preceding sentence,
no party may assign any of its rights under this  Agreement  without the written
consent of the other parties.

     SECTION 9.08 Expenses and Remedies.

          (a) All costs and expenses  incurred in connection with this Agreement
     and the  transactions  contemplated  hereby  shall be  borne  by the  party
     incurring such expense, except as set forth in the next four paragraphs.

          (b)  Notwithstanding  Section 9.08(a),  (i) if a Purchaser  terminates
     this Agreement  pursuant to Section  7.01(c)(i)  (due to material breach of
     any  covenant or  agreement  or an  intentional  and willful  breach of any
     representation  or  warranty by the  Company)  or  (c)(ii),  or (ii) if the
     Company  terminates  this  Agreement  pursuant to Section  7.01(d)(ii)  (by
     virtue of a failure  of the  condition  set forth in  Section  6.02(d))  or
     7.01(d)(iii),  the Company shall pay TSC a termination fee of $750,000 (the
     "Termination  Fee")  within  ten  (10)  days  of  such  termination,  which
     Termination  Fee shall be deemed to reimburse  Purchasers  for their legal,
     accounting  and other  out-of-pocket  expenses as well as the damages  they
     will have suffered by virtue of such termination.

          (c) Notwithstanding Section 9.08(a), (i) if a Purchaser or the Company
     terminates this Agreement pursuant to Section 7.01(b)(i) or (ii), (ii) if a
     Purchaser  terminates  this Agreement  pursuant to Section  7.01(c)(i) (for
     reasons  other  than as  provided  in Section  9.08(b))  or  (c)(iii)  (for
     failures of the conditions set forth in 6.03(a), 6.03(b), 6.03(d), 6.03(f),
     6.03(g) (provided that no amount shall be payable if the failure is not due
     to any fault of the Company),  6.03(h), 6.03(i), 6.03(j), 6.03(k), 6.03(l),
     6.03(m),  or  6.03(n)),  or (iii) the  Company  terminates  this  Agreement
     pursuant to Section  7.01(d)(ii) (other than for failure of a condition set
     forth in section 6.02(d)),  the Company shall reimburse  Purchasers for the
     reasonable  out-of-pocket  expenses (including reasonable fees and expenses
     of legal counsel)  incurred by Purchasers in connection with this Agreement
     or the matters  contemplated  hereby (the  "Purchasers'  Expenses"),  which
     reimbursable amount shall not to exceed $600,000 in the aggregate.

          (d)  Notwithstanding  Section 9.08(a),  if (i) either Purchaser or the
     Company terminates this Agreement pursuant to any provision of Section 7.01
     (other than a termination  for which a Termination Fee was paid pursuant to
     Section  9.08(b) and other than a  termination  by the Company  pursuant to
     Section  7.01(d)(i)),  and (ii) during the period ending twelve (12) months
     after  termination of this Agreement,  the Company enters into an agreement
     relating to a Transaction Proposal,  then immediately prior to consummation
     of such transaction,  the Company shall pay the Termination Fee;  provided,
     however,  that the  Company  shall  receive  a credit  for any  Purchasers'
     Expenses paid pursuant to Section  9.08(c) and it being  understood that if
     the  Termination  Fee is paid  pursuant to Section  9.08(b) it shall not be
     required to be paid subsequently under this Section 9.08(d).

          (e)  Notwithstanding  Section  9.08(a),  upon  the  occurrence  of the
     Closing,  the Company shall  reimburse the Purchasers  for the  Purchasers'
     Expenses,  which reimbursable  amount shall not be subject to the limit set
     forth in Section 9.08(c).

     SECTION 9.09 Transfer of Shares. Each Purchaser understands and agrees that
the Shares have not been  registered  under the Securities Act or the securities
laws of any state and that they may be sold or otherwise disposed of only in one
or more transactions  registered under the Securities Act and, where applicable,
such laws or as to which an exemption from the registration  requirements of the
Securities Act and,  where  applicable,  such laws is available.  Each Purchaser
acknowledges that except as provided in the Registration  Rights  Agreement,  it
has no right to require  the  Company to register  the  Shares.  Each  Purchaser
understands and agrees that each certificate representing shares of Common Stock
shall bear the following legends:


        "THE SECURITIES  REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
        REGISTERED  UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES
        LAWS OF ANY STATE AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF
        EXCEPT PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT UNDER
        SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR AN APPLICABLE
        EXEMPTION TO THE REGISTRATION REQUIREMENTS OF SUCH ACT OR SUCH
        LAWS."

and Purchaser  agrees to transfer shares of Common Stock only in accordance with
the provisions of such legends. After termination of the requirement that all or
part of such  legend be placed  upon a  certificate,  the  Company  shall,  upon
receipt  by the  Company of  evidence  reasonably  satisfactory  to it that such
requirement  has terminated  and upon the written  request of the holders of the
Shares issue certificates for the Shares that do not bear such legend.

     SECTION 9.10 Governing Law; Consent to  Jurisdiction.  This Agreement shall
be governed by and construed  and enforced in accordance  with the internal laws
of  the  State  of New  York,  except  to  the  extent  that  Massachusetts  law
mandatorily governs.  Each of the Company and Purchasers  irrevocably submits to
the personal exclusive  jurisdiction of the United States District Court for the
Southern  District  of New York for the  purposes  of any suit,  action or other
proceeding arising out of this Agreement or any transaction  contemplated hereby
(and, to the extent permitted under applicable rules of procedure, agrees not to
commence any action,  suit or proceeding  relating hereto except in such court).
Each of the Company and  Purchasers  further  agree that service of any process,
summons,  notice or document hand  delivered or sent by registered  mail to such
party's  respective  address set forth in Section 9.10 will be effective service
of process for any action,  suit or  proceeding  in New York with respect to any
matters  to  which  it  has  submitted  to  jurisdiction  as  set  forth  in the
immediately preceding sentence.  Each of the Company and Purchasers  irrevocably
and  unconditionally  waive any  objection to the laying of venue of any action,
suit  or  proceeding   arising  out  of  this  Agreement  or  the   transactions
contemplated  hereby  in the  United  States  District  Court  for the  Southern
District of New York, and hereby further irrevocably and  unconditionally  waive
and  agree not to plead or claim in such  court  that any such  action,  suit or
proceeding brought in such court has been brought in an inconvenient forum.

     SECTION 9.11 Third Party  Beneficiaries.  As provided in Section 5.12,  the
directors of the Company are the intended  beneficiaries of that section of this
Agreement.  Except as  provided  in  Section  5.12,  nothing  contained  in this
Agreement is intended to confer upon any person or entity other than the parties
hereto and their respective successors and permitted assigns, any benefit, right
or remedies under or by reason of this Agreement.

     SECTION 9.12 Mutual  Drafting.  This Agreement is the mutual product of the
parties  hereto,  and each  provision  hereof  has been  subject  to the  mutual
consultation, negotiation and agreement of each of the parties, and shall not be
construed for or against any party hereto.

     SECTION  9.13  Further  Representations.   Each  party  to  this  Agreement
acknowledges  and  represents  that it has  been  represented  by its own  legal
counsel in connection with the transactions contemplated by this Agreement, with
the  opportunity  to seek advice as to its legal rights from such counsel.  Each
party further  represents that it is being  independently  advised as to the tax
consequences  of the  transactions  contemplated  by this  Agreement  and is not
relying on any  representation  or statements made by the other party as to such
tax consequences.

                               REGISTRATION RIGHTS

                  SECTION 2.1 Shelf Registration.

                  (a) As soon as practicable but in any event not later than the
     date  (the  "Filing  Date")  that is  thirty  (30)  days,  in the case of a
     Registration  Statement on Form S-3 (or successor or replacement  form) and

     Securities  for resale by such holders in the manner or manners  designated

     Registration  continuously effective under the Securities Act until the end
     of the Effectiveness Period.

                  (b) If the Initial Shelf  Registration or any Subsequent Shelf
     Registration  (as defined  below)  ceases to be effective for any reason at
     any  time  during  the   Effectiveness   Period  (other  than  because  all
     Registrable  Securities  shall  have been sold or shall  have  ceased to be
     Registrable Securities),  the Company shall use all commercially reasonable
     best efforts to obtain the prompt  withdrawal of any order  suspending  the
     effectiveness  thereof,  and in any event shall within  thirty days of such
     cessation  of  effectiveness  amend  the  Shelf  Registration  in a  manner
     reasonably  expected to obtain the  withdrawal of the order  suspending the
     effectiveness  thereof,  or file an additional Shelf Registration  covering
     all of the Registrable Securities (a "Subsequent Shelf Registration"). If a
     Subsequent  Shelf   Registration  is  filed,  the  Company  shall  use  all
     commercially   reasonable  best  efforts  to  cause  the  Subsequent  Shelf
     Registration to become  effective as promptly as is practicable  after such
     filing and to keep such Registration Statement continuously effective until
     the end of the Effectiveness Period.

                  (c)  The  Company  shall   supplement   and  amend  the  Shelf
     Registration  if  required  by  the  rules,   regulations  or  instructions
     applicable  to the  registration  form used by the  Company  for such Shelf
     Registration, if required by the Securities Act, or if reasonably requested
     by any holder of the Registrable  Securities  covered by such  Registration
     Statement or by any Managing Underwriter of such Registrable Securities.

                  (d) Each holder of  Registrable  Securities  agrees that if it
     wishes to sell any Registrable  Securities pursuant to a Shelf Registration
     and related Prospectus,  it will do so only in accordance with this Section
     2.1(d). Each holder of Registrable Securities agrees to give written notice
     to the  Company  at least  six (6)  Business  Days  prior  to any  intended
     distribution of Registrable Securities under the Shelf Registration,  which
     notice  shall  specify the date on which such holder  intends to begin such
     distribution  and any  information  with  respect  to such  holder  and the
     intended distribution of Registrable  Securities by such holder required to
     amend  or  supplement  the  Registration  Statement  with  respect  to such
     intended  distribution of Registrable  Securities by such holder;  provided
     that no holder may give such  notice  unless  such  notice,  together  with
     notices given by other holders of  Registrable  Securities  joining in such
     notice or giving similar notices,  covers at least  ___________  Shares. As
     promptly as is practicable  after the date such notice is provided,  and in
     any event within five (5) Business Days after such date,  the Company shall
     either:

                      (i) (A)  prepare  and file  with the SEC a  post-effective
              amendment to the Shelf Registration or a supplement to the related
              Prospectus   or  a   supplement   or  amendment  to  any  document
              incorporated  therein by reference or any other required document,
              so that such  Registration  Statement  will not contain any untrue
              statement  of a  material  fact or omit to state a  material  fact
              required to be stated  therein or necessary to make the statements
              therein not  misleading,  and so that, as thereafter  delivered to
              purchasers of the Registrable  Securities  being sold  thereunder,
              such  Prospectus  will  not  contain  any  untrue  statement  of a
              material  fact or omit to state a  material  fact  required  to be
              stated  therein or necessary to make the  statements  therein,  in
              light  of the  circumstances  under  which  they  were  made,  not
              misleading; (B) provide each Notice Holder a copy of any documents
              filed pursuant to Section 2.1(d)(i)(A); and (C) inform each Notice
              Holder that the  Company  has  complied  with its  obligations  in
              Section  2.1(d)(i)(A)  and that  the  Registration  Statement  and
              related  Prospectus  may be used for the purpose of selling all or
              any of such  Registrable  Securities  (or that, if the Company has
              filed a post-effective  amendment to the Shelf  Registration which
              has not yet been declared effective,  the Company will notify each
              Notice Holder to that effect, will use all commercially reasonable
              best efforts to secure the  effectiveness  of such  post-effective
              amendment and will  immediately  so notify each Notice Holder when
              the amendment has become effective);  each Notice Holder will sell
              all or any of such  Registrable  Securities  pursuant to the Shelf
              Registration and related Prospectus only during the sixty (60) day
              period in the case of registration on Form S-3, or the ninety (90)
              day period in the case of registration on any other form available
              for  registration,  commencing  with the date on which the Company
              gives  notice  (such sixty (60) or ninety (90) day period,  as the
              case may be,  to be  calculated  without  regard  to any  Deferral
              Period),  pursuant to Section 2.1(d)(i)(C),  that the Registration
              Statement and Prospectus may be used for such purpose; each Notice
              Holder  agrees  that it will not sell any  Registrable  Securities
              pursuant to such  Registration  Statement or Prospectus after such
              Selling  Period  without  giving a new notice of intention to sell
              pursuant to Section  2.1(d) hereof and receiving a further  notice
              from the Company pursuant to Section 2.1(d)(i)(C) hereof; or

                      (ii) if, in the judgment of the  Company,  it is advisable
              to  suspend  use of the  Prospectus  for a  period  of time due to
              pending material corporate developments or similar material events
              that  have not yet been  publicly  disclosed  and as to which  the
              Company  believes  public  disclosure  will be  prejudicial to the
              Company,  the  Company  shall  deliver a  certificate  in writing,
              signed by its Chief Executive Officer,  Chief Financial Officer or
              General  Counsel,  to the Notice Holders,  the Special Counsel and
              the Managing Underwriters,  if any, to the effect of the foregoing
              and, upon receipt of such  certificate,  each such Notice Holder's
              Selling  Period  will not  commence  until  such  Notice  Holder's
              receipt  of  copies  of the  supplemented  or  amended  Prospectus
              provided  for in  Section  2.1(d)(i)(A)  hereof,  or  until  it is
              advised in writing by the Company that the Prospectus may be used,
              and has received copies of any additional or supplemental  filings
              that are incorporated or deemed  incorporated by reference in such
              Prospectus.  The Company will use all commercially reasonable best
              efforts to ensure that the use of the  Prospectus  may be resumed,
              and the  Selling  Period  will  commence,  upon the earlier of (x)
              public disclosure of such pending material  corporate  development
              or similar  material event or (y) a  determination  by the Company
              that,  in the judgment of the Company,  public  disclosure of such
              material corporate development or similar material event would not
              be prejudicial to the Company.  Notwithstanding the foregoing, the
              Company shall not under any  circumstances be entitled to exercise
              its right under Section  2.1(d)(ii) to defer the commencement of a
              Selling Period more than one time in any three (3)-month period or
              two times in any twelve (12)-month period, and the period in which
              a Selling  Period is suspended  shall not exceed fifteen (15) days
              unless the Company shall  deliver to such Notice  Holders a second
              certificate  to the effect set forth  above,  which shall have the
              effect of extending the period during which such Selling Period is
              deferred by up to an additional fifteen (15) days, or such shorter
              period of time as is specified in such second  certificate.  In no
              event shall the Company be permitted  to extend the period  during
              which such  Selling  Period is deferred  from and after the date a
              Notice Holder  provides  notice to the Company in accordance  with
              Section  2.1(d)(ii)  of its  intention to  distribute  Registrable
              Securities beyond such thirty (30)-day period.

                  SECTION 2.2 Demand Registration.

                  (a) At any time during the Effectiveness Period, any holder or
     holders of  Registrable  Securities  (the "Demand  Holders") may request in
     writing that the Company file a Registration Statement under the Securities
     Act  covering  the  registration  of all or a  portion  of the  Registrable
     Securities then held by the Demand Holders (a "Demand Registration"). After
     the date on which the Company  receives  such a request,  the Company shall
     use all  commercially  reasonable  best efforts (i) to file a  Registration
     Statement under the Securities Act on the appropriate  form (using Form S-3
     or other "short form," if available and advised by counsel) covering all of
     the Registrable  Securities specified by the holders within forty-five (45)
     days after the date of such request (thirty (30) days in the case of a Form
     S-3) and (ii) to cause such Registration Statement to be declared effective
     within  sixty  (60) days  (forty-five  (45) days in the case of a Form S-3)
     after the filing  referenced in clause (i) above. The Company will keep the
     Demand  Registration  current and effective for at least one hundred twenty
     (120)  days (such one  hundred  twenty  (120) day  period to be  calculated
     without  regard to any Deferral  Period),  or a shorter period during which
     the  holders  shall  have sold all  Registrable  Securities  covered by the
     Demand Registration.

                  (b) In the event a holder of  Registrable  Securities  makes a
     demand to register pursuant to Section 2.2 and later determines not to sell
     Registrable  Securities  pursuant to such  registration,  the Company shall
     cease all  efforts to secure  registration  for such  holder's  Registrable
     Securities and shall take all action  necessary to prevent the commencement
     of effectiveness  for any registration that it is preparing or has prepared
     in  connection  with  the  withdrawn  request,  and  such  holder's  Demand
     Registration shall be reinstated as if never exercised;  provided, however,
     that such holder  withdrawing  such  demand  shall pay all of the costs and
     expenses  incurred by the Company in connection with such withdrawn demand,
     unless  the  withdrawal  is a result  of a  breach  by the  Company  of its
     obligations under this Agreement.

                  (c)  National  Union  shall  be  entitled  to two  (2)  Demand
     Registrations  pursuant  to  Section  2.2,  provided  that it shall  not be
     entitled  to  exercise  more than one (1) Demand  Registrations  during any
     twelve (12) month period.  TSC,  O&G,  ULLICO and BLUM  (together  with The
     Common  Fund and PB  Capital)  shall each have one (1) Demand  Registration
     right pursuant to Section 2.2.

                  (d)  Notwithstanding  the  provisions  of Section  2.2, if the
     Company is requested to file any registration under Section 2.2:

                      (i) The  Company  shall have the right to defer the filing
              of a  Registration  Statement  relating  to a Demand  Registration
              during the ninety (90) days  following the  effective  date of any
              other Registration  Statement pertaining to an underwritten public
              offering of securities  for the account of the Company or security
              holders of the Company or such earlier  date as such  distribution
              shall be completed; or

                  (ii) The  Company  shall  have the right to defer  the  filing
              after receipt of the Demand  Holders  request or if a Registration
              Statement  relating  to a Demand  Registration  has  already  been
              filed,  the Company  may cause the  Registration  Statement  to be
              withdrawn and its effectiveness to be terminated,  or may postpone
              amending or supplementing  the Registration  Statement,  until the
              Board of Directors determines that the circumstances requiring the
              withdrawal or postponement no longer exist, if, in the judgment of
              the Company,  (i) it is advisable to suspend use of the Prospectus
              for  a  period  of  time  due  to   pending   material   corporate
              developments  or similar  material  events  that have not yet been
              publicly  disclosed  and as to which the Company  believes  public
              disclosure will be prejudicial to the Company or (ii) the Board of
              Directors of the Company  determines in good faith that there is a
              valid  business  purpose or reason  for  delaying  such  filing or
              effectiveness. The Company shall deliver a certificate in writing,
              signed by its Chief Executive Officer,  Chief Financial Officer or
              General  Counsel,  to the holders of Registrable  Securities,  the
              Special  Counsel  and the  Managing  Underwriters,  if any, to the
              effect of the  foregoing  and,  upon receipt of such  certificate,
              each such  holder's  Selling  Period will not commence  until such
              holder's   receipt  of  copies  of  a   supplemented   or  amended
              Prospectus,  or until it is advised in writing by the Company that
              the  Prospectus  may be  used,  and  has  received  copies  of any
              additional or supplemental filings that are incorporated or deemed
              incorporated by reference in such Prospectus. The Company will use
              all commercially reasonable best efforts to ensure that the use of
              the  Prospectus  may be  resumed,  and  the  Selling  Period  will
              commence,  upon  the  earlier  of (x)  public  disclosure  of such
              pending material  corporate  development or similar material event
              or (y) a determination by the Company that, in the judgment of the
              Company,  public disclosure of such material corporate development
              or similar material event would not be prejudicial to the Company.
              Notwithstanding  the  foregoing,  the Company  shall not under any
              circumstances be entitled to exercise its right under this Section
              2.2(d)(ii) to defer the commencement of a Selling Period more than
              sixty (60) days during any twelve (12)-month period.

                  (e) A Demand  Registration  shall  not  count as such  until a
     Registration Statement becomes effective;  provided,  that if, after it has
     become effective,  the offering  pursuant to the Registration  Statement is
     interfered with by any stop order, injunction or other order or requirement
     of the SEC or any other governmental authority,  such registration shall be
     deemed not to have been  effected  unless  such stop order,  injunction  or
     other order  shall  subsequently  have been  vacated or  otherwise  removed
     within fifteen (15) days of the imposition thereof.

                  (f)  The  Demand  Holders  shall  select  the  underwriter  or
     underwriters (including Managing Underwriter) of any offering pursuant to a
     Demand Registration, subject to the approval of the Company, which approval
     shall not be unreasonably withheld.

              SECTION 2.3 Piggyback Registration.

                  (a) Subject to applicable  stock exchange rules and securities
      regulations, at least thirty (30) days prior to any public offering of any
      of its capital  stock of the Company for the account of the Company or any
      other Person (other than a  Registration  Statement on Form S-4 or S-8 (or
      any successor forms under the Securities Act), relating solely to employee
      benefit plans or any  transaction  governed by Rule 145 of the  Securities
      Act or  Registration  Statement  filed pursuant to the Shelf  Registration
      under Section 2.1 of this Agreement or any substantially  comparable shelf
      registration  right granted by the company to any  shareholder not a party
      to this Agreement), the Company shall give written notice of such proposed
      filing  and of the  proposed  date  thereof to the  holders  and if, on or
      before  the  twentieth  (20th)  day (or  such  earlier  day  specified  if
      registration is for the account of any other Person) following the date on
      which such notice is given, (i) a Registration Statement covering the sale
      of all of the  Registrable  Securities is not then effective and available
      for sales  thereof  by the  holders  and (ii) the  Company  shall  receive
      written  requests from any holders of  Registrable  Securities  requesting
      that the Company include among the securities covered by such Registration
      Statement  any  or  all  of  the  Registrable   Securities  for  offering,
      specifying the amount of Registrable  Securities  that such holder intends
      to sell and such holder's  intended  method of  distribution,  the Company
      shall include such Registrable Securities in such Registration  Statement,
      if  filed,  so as to  permit  such  Registrable  Securities  to be sold or
      disposed  of in the manner and on the terms of the  offering  thereof  set
      forth in such request.  Each such registration shall hereinafter be called
      a "Piggyback  Registration."  The Company shall select the  underwriter or
      underwriters,  including Managing Underwriter, of any offering pursuant to
      a Registration Statement filed pursuant to this Section 2.3, provided that
      any selected  underwriter shall be a well-recognized firm in good standing
      of national reputation.

                  (b) Upon receipt of a request for Piggyback Registration,  the
     Company  shall use all  commercially  reasonable  best efforts to cause all
     Registrable  Securities which the Company has been requested to register to
     be registered  under the Securities  Act to the extent  necessary to permit
     their sale or other  disposition in accordance with the intended methods of
     distribution  specified in the request of such Holder;  provided,  however,
     that the Company shall have the right,  prior to the effective  date of the
     Registration  Statement,  to  postpone  or  withdraw  such  a  registration
     effected  pursuant to this Section 2.3 without  obligation  to the holders,
     other than the  Company's  obligation  to pay the expenses  incurred by the
     holders in connection with the registration; provided, further, that if the
     registration is pursuant to a Demand  Registration,  the Company shall only
     have the right to defer the registration in accordance with Section 2.2(d).
     In the event a holder of Registrable  Securities makes a demand to register
     pursuant to this Section 2.3 and later  determines not to sell  Registrable
     Securities  pursuant  to such  registration,  the  Company  shall cease all
     efforts to secure registration for such holder's Registrable Securities.

                  (c)  If  such  registration   being  effected  pursuant  to  a
     Piggyback Registration is a Company registration or a registration pursuant
     to an underwritten  offering, the shares of Common Stock available for sale
     shall be allocated in accordance with Article III of this Agreement.

                  (d) No  registration  effected under Section 2.3 shall relieve
     the Company of its obligation to effect a demand registration under Section
     2.2,  nor shall any  registration  under this Section 2.3 be deemed to have
     been effected under Section 2.2.


                                   ARTICLE III

                              UNDERWRITERS' CUTBACK

                  SECTION 3.1 Underwriter's Cutback.

                  (a) If, in connection  with any  underwritten  public offering
     for the account of the Company, the Managing  Underwriter(s)  thereof shall
     impose a limitation on the number of shares of Common Stock (the  "Saleable
     Number") which may be included in the  Registration  Statement that is less
     than all of the shares of Common Stock sought to be registered  because, in
     such Managing Underwriter(s)'  commercially reasonable judgment,  marketing
     or other factors dictate such limitation is necessary to facilitate  public
     distributions,  then the number of shares of Common Stock  offered shall be
     limited to the Saleable  Number.  The Company will  promptly so advise each
     holder of Registrable Securities that has requested registration,  and will
     include shares of Common Stock in such  registration in the following order
     of priority:  (A) the shares of Common Stock the Company desires to include
     in  such  registration  up to the  total  number  of  shares  sought  to be
     registered;  (B) the  Registrable  Securities  that the  holders  desire to
     include in such  registration up to the total sought to be registered;  and
     (C) the balance of securities, if any, to be registered by other holders of
     the  Company's  Common  Stock to the  extent  such  security  holders  have
     piggyback  registration  rights and have sought to include their securities
     in such registration,  in each case until the aggregate number of shares of
     Common Stock included in such  registration  is equal to the number thereof
     that, in the opinion of such Managing  Underwriter(s),  can be sold without
     adversely affecting the marketability thereof.

                  (b) If, in connection  with any  underwritten  public offering
     for the account of any security holder of the Company exercising its demand
     registration right (other than the holder of Registrable  Securities),  the
     Saleable Number which may be included in the Registration Statement is less
     than all of the shares of Common Stock sought to be registered  because, in
     the Managing Underwriter(s)' commercially reasonable judgment, marketing or
     other factors  dictate such  limitation  is necessary to facilitate  public
     distributions,  then the number of  securities  offered shall be limited to
     the Saleable  Number.  The Company  will  promptly so advise each holder of
     Registrable Securities that has requested registration, and will include in
     such  registration  in the following  order of priority:  (A) the shares of
     Common Stock sought to be  registered  by holders of the  Company's  Common
     Stock who have exercised their demand registration right (to the extent the
     holders  exercising  such rights  possessed  such rights  prior to the date
     hereof); (B) the Registrable  Securities that the holders desire to include
     in such registration up to the total sought to be registered and the shares
     of Common Stock sought to be registered by holders of the Company's  Common
     Stock who have exercised their demand registration right (to the extent the
     holders  exercising  such rights  obtained such rights on or after the date
     hereof); (C) any securities to be registered for the account of the Company
     together with the balance of securities,  if any, to be registered by other
     holders of the Company's  Common Stock to the extent such security  holders
     have  piggyback  registration  rights  and have  sought  to  include  their
     securities in such registration, in each case until the aggregate number of
     shares of Common Stock included in such registration is equal to the number
     thereof that, in the opinion of such Managing  Underwriter(s),  can be sold
     without adversely affecting the marketability thereof.

                  (c) If, in connection  with any  underwritten  public offering
     for the account of the holders of Registrable  Securities pursuant to their
     Demand  Registration  right,  as the case may be, the Saleable Number which
     may be  included  in the  Registration  Statement  is less  than all of the
     shares  of  Common  Stock  sought  to  be  registered   because,   in  such
     underwriter(s)'   commercially  reasonable  judgment,  marketing  or  other
     factors  dictate  such   limitation  is  necessary  to  facilitate   public
     distributions,  then the  Company  will  promptly  so advise each holder of
     Registrable Securities that has requested registration, and will include in
     such  registration in the following order of priority:  (A) the Registrable
     Shares that the holders who have exercised their Demand  Registration right
     desire to  include  in such  registration;  (B) the  shares of  Registrable
     Securities  sought to be registered by holders  exercising  their Piggyback
     Registration  rights;  and  (C) any  securities  to be  registered  for the
     account of the Company together with the balance of securities,  if any, to
     be registered by other holders of the Company's  Common Stock to the extent
     such security holders have piggyback registration rights and have sought to
     include  their  securities  in such  registration,  in each case  until the
     aggregate number of shares of Common Stock included in such registration is
     equal  to  the  number  thereof  that,  in the  opinion  of  such  Managing
     Underwriter(s),  can be sold without adversely  affecting the marketability
     thereof.

                  (d) If the number of shares of Common  Stock that the Managing
     Underwriter(s) advise the Company can be registered is less than all of the
     Registrable Securities that the holders have sought to register each holder
     requesting  registration  pursuant to rights  granted under this  Agreement
     shall be  allocated  the  number of  Registrable  Securities  eligible  for
     registration pro rata in proportion to the number of Registrable Securities
     sought to be registered under the applicable Registration Statement without
     regard to the securities held by holders who have not sought registration.


                                   ARTICLE IV

                             REGISTRATION PROCEDURES

                  SECTION 4.1  Registration  Procedures.  In connection with the
     Company's  registration  obligations  under Article II hereof,  the Company
     shall  effect  such  registrations  to permit  the sale of the  Registrable
     Securities in accordance with the intended method or methods of disposition
     thereof,  and  pursuant  thereto  the  Company  shall as  expeditiously  as
     possible:

                  (a) Prepare and file with the SEC a Registration  Statement or
     Registration  Statements on the form  specified in this Agreement or, if no
     form has been specified,  on any appropriate  form under the Securities Act
     available for the sale of the Registrable Securities by the holders thereof
     in accordance with the intended method or methods of distribution  thereof,
     and use all  commercially  reasonable  best  efforts  to  cause  each  such
     Registration Statement to become effective and remain effective as provided
     herein;  provided,  that before filing any such  Registration  Statement or
     Prospectus or any amendments or  supplements  thereto (other than documents
     that  would  be  incorporated  or  deemed  to be  incorporated  therein  by
     reference and that the Company is required by applicable securities laws or
     stock  exchange  requirements  to file) the  Company  shall  furnish to the
     holders of  Registrable  Securities,  the Special  Counsel and the Managing
     Underwriters  of  such  offering,  if any,  copies  of all  such  documents
     proposed to be filed,  which documents will be subject to the review of the
     holders of Registrable  Securities,  the Special  Counsel and such Managing
     Underwriters,  and  the  Company  shall  not  file  any  such  Registration
     Statement or amendment thereto or any Prospectus or any supplement  thereto
     (other than such documents  which,  upon filing,  would be  incorporated or
     deemed to be  incorporated  by  reference  therein  and that the Company is
     required by applicable  securities  laws or stock exchange  requirements to
     file) to which the  holders of a  majority  of the  Registrable  Securities
     covered  by  such  Registration  Statement  or the  Special  Counsel  shall
     reasonably object in writing within two full Business Days after receipt of
     such materials.

                  (b)  Prepare  and  file  with  the  SEC  such  amendments  and
     post-effective   amendments  to  each  Registration  Statement  as  may  be
     necessary to keep such Registration  Statement  continuously  effective for
     the applicable period specified in Article 2; cause the related  Prospectus
     to be  supplemented  by  any  required  Prospectus  supplement,  and  as so
     supplemented  to be filed  pursuant to Rule 424 (or any similar  provisions
     then in force) under the Securities  Act; and comply with the provisions of
     the  Securities  Act with  respect  to the  disposition  of all  securities
     covered by such  Registration  Statement  during the  applicable  period in
     accordance with the intended  methods of disposition by the sellers thereof
     set forth in such  Registration  Statement as so amended or such Prospectus
     as so supplemented.

                  (c) Notify the selling holders of Registrable Securities,  the
     Special Counsel and the Managing  Underwriters,  if any, promptly,  and (if
     requested  by any such person)  confirm such notice in writing,  (i) when a
     Prospectus,   any  Prospectus  supplement,  a  Registration  Statement,  an
     amendment or a  post-effective  amendment to a  Registration  Statement has
     been filed with the SEC, and, with respect to a  Registration  Statement or
     any post-effective  amendment,  when the same has become effective, (ii) of
     any request by the SEC or any other federal or state governmental authority
     for  amendments  or  supplements  to a  Registration  Statement  or related
     Prospectus  or for  additional  information,  and of the  contents  of such
     request,  (iii) of the  issuance  by the SEC or any other  federal or state
     governmental  authority of any stop order suspending the effectiveness of a
     Registration  Statement or the initiation or threatening of any proceedings
     for that  purpose,  (iv) of the receipt by the Company of any  notification
     with respect to the  suspension  of the  qualification  or  exemption  from
     qualification  of  any  of  the  Registrable  Securities  for  sale  in any
     jurisdiction  or the  initiation or  threatening of any proceeding for such
     purpose,  (v) of the  existence of any fact or happening of any event which
     makes any  statement of a material fact in such  Registration  Statement or
     related   Prospectus  or  any  document   incorporated   or  deemed  to  be
     incorporated  therein by reference untrue or which would require the making
     of any changes in the  Registration  Statement or Prospectus in order that,
     in the case of the Registration  Statement,  it will not contain any untrue
     statement of a material fact or omit to state any material fact required to
     be  stated  therein  or  necessary  to  make  the  statements  therein  not
     misleading, and that in the case of the Prospectus, it will not contain any
     untrue  statement of a material  fact or omit to state any material fact or
     omit to state any material fact required to be stated  therein or necessary
     to make the statements  therein,  in the light of the  circumstances  under
     which they were made, not  misleading,  provided that the Company shall not
     be required  to  disclose  such fact or event if such fact or event has not
     been,  and is not  required  to be,  publicly  disclosed,  and  (vi) of the
     Company's  determination that a post-effective  amendment to a Registration
     Statement or supplement to a Prospectus would be appropriate.

                  (d) Use all commercially reasonable best efforts to obtain the
     withdrawal of any order  suspending  the  effectiveness  of a  Registration
     Statement,  or the  lifting  of any  suspension  of the  qualification  (or
     exemption from qualification) of any of the Registrable Securities for sale
     in any jurisdiction, at the earliest possible moment.

                  (e)  If  reasonably  requested  by  a  holder  of  Registrable
     Securities,  the Special  Counsel,  the Managing  Underwriters,  if any, or
     requested by the holders of a majority of the Registrable  Securities being
     sold, (i) promptly  incorporate in a Prospectus  supplement or amendment or
     post-effective  amendment to a Registration  Statement such  information as
     the holders of Registrable  Securities,  the Special Counsel,  the Managing
     Underwriters,  if any, or such holders,  in connection with any offering of
     Registrable  Securities,  agree  should be included  therein as required by
     applicable  law,  and (ii) make all  required  filings  of such  Prospectus
     supplement or such amendment or post-effective  amendment as promptly as is
     practicable  after the Company has received  notification of the matters to
     be incorporated in such Prospectus supplement or post-effective  amendment;
     provided,  that the Company shall not be required to take any actions under
     this Section 4.1(e) that are not, in the reasonable  opinion of counsel for
     the Company, in compliance with or required by applicable law.

                  (f) Furnish to each selling holder of Registrable  Securities,
     the Special Counsel, and each Managing Underwriter, if any, without charge,
     at least one conformed copy of the Registration Statement or Statements and
     any  amendment  thereto,   including  financial  statements  but  excluding
     schedules,  all documents incorporated or deemed to be incorporated therein
     by reference and all exhibits (unless  requested in writing by such holder,
     Special Counsel or Managing Underwriter).

                  (g) Deliver to each selling holder of Registrable  Securities,
     the Special Counsel, and each Managing  Underwriter,  if any, in connection
     with any offering of Registrable Securities, without charge, as many copies
     of the Prospectus or Prospectuses  relating to such Registrable  Securities
     (including  each  preliminary  prospectus)  and any amendment or supplement
     thereto as such  persons may  reasonably  request;  and the Company  hereby
     consents to the use of such  Prospectus  or each  amendment  or  supplement
     thereto by each of the selling  holders of  Registrable  Securities and the
     underwriters,  if any,  in  connection  with any  offering  and sale of the
     Registrable  Securities  covered by such  Prospectus  or any  amendment  or
     supplement thereto.

                  (h) Prior to any public offering of Registrable Securities, to
     register or qualify or cooperate  with the selling  holders of  Registrable
     Securities,  the Managing Underwriters,  if any, and the Special Counsel in
     connection with the registration or  qualification  (or exemption from such
     registration or qualification) of such Registrable Securities for offer and
     sale under the securities or Blue Sky laws of such jurisdictions within the
     United  States as any  selling  holder or Managing  Underwriter  reasonably
     requests  in  writing  to the  Company;  keep  each  such  registration  or
     qualification  (or exemption  therefrom)  effective  during the period such
     Registration  Statement is required to be kept effective and do any and all
     other acts or things  necessary or advisable to enable the  disposition  in
     such jurisdictions of the Registrable  Securities covered by the applicable
     Registration Statement;  provided, that the Company will not be required to
     (i) qualify  generally to do business in any  jurisdiction  where it is not
     then so qualified or (ii) take any action that would  subject it to general
     service of process in suits or to taxation in any such  jurisdiction  where
     it is not then so subject.

                  (i) Cause the Registrable Securities covered by the applicable
     Registration  Statement  to be  registered  with or  approved by such other
     governmental  agencies or authorities  within the United States,  except as
     may be required  solely as a consequence  of the nature of a selling holder
     of Registrable Securities,  in which case the Company will cooperate in all
     reasonable respects with the filing of such Registration  Statement and the
     granting  of such  approvals,  as may be  necessary  to enable the  selling
     holder  or  holders  thereof  or the  Managing  Underwriters,  if  any,  to
     consummate the disposition of such Registrable Securities.

                  (j) During any  Selling  Period  (other than during a Deferral
     Period),  immediately  upon the existence of any fact or the  occurrence of
     any event as a result of which a Registration  Statement  shall contain any
     untrue  statement  of a material  fact or omit to state any  material  fact
     required to be stated therein or necessary to make the  statements  therein
     not  misleading,  or a Prospectus  shall contain any untrue  statement of a
     material  fact or omit to state any  material  fact  required  to be stated
     therein or necessary to make the  statements  therein,  in the light of the
     circumstances  under which they were made, not misleading,  promptly notify
     the holders, Special Counsel and any Managing Underwrite to discontinue use
     of such Registration  Statement;  promptly prepare and file an amendment or
     post-effective  amendment to each Registration Statement or a supplement to
     the related Prospectus or any document incorporated therein by reference or
     file any other  required  document  (such as a Current  Report on Form 8-K)
     that would be incorporated by reference into the Registration  Statement so
     that the Registration Statement shall not contain any untrue statement of a
     material  fact or omit to state any  material  fact  required  to be stated
     therein or necessary to make the statements therein not misleading,  and so
     that the  Prospectus  will not contain any untrue  statement  of a material
     fact or omit to state any material  fact  required to be stated  therein or
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading,  as thereafter delivered to the
     purchasers of the Registrable Securities being sold thereunder, and, in the
     case of a  post-effective  amendment to a Registration  Statement,  use all
     commercially  reasonable  best  efforts to cause it to become  effective as
     promptly as is practicable.

                  (k) Enter into such agreements (including,  in the event of an
     Underwritten  Offering,  an  underwriting  agreement  in  form,  scope  and
     substance  as is  customary in  Underwritten  Offerings)  and take all such
     other  actions  in  connection  therewith  (including,  in the  event of an
     underwritten   offering,   those  reasonably   requested  by  the  Managing
     Underwriters,  if any,  or the  holders  of a majority  of the  Registrable
     Securities  being sold) in order to expedite or facilitate the  disposition
     of such Registrable  Securities and in such  connection,  whether or not an
     underwriting  agreement  is entered  into,  and if the  registration  is an
     underwritten  registration,  (i) make such  representations and warranties,
     subject  to  the  Company's  ability  to do  so,  to the  holders  of  such
     Registrable Securities and the underwriters with respect to the business of
     the Company and its subsidiaries,  the Registration  Statement,  Prospectus
     and  documents   incorporated  by  reference  or  deemed   incorporated  by
     reference,  if any,  in each  case,  in form,  substance  and  scope as are
     customarily  made by issuers to underwriters in underwritten  offerings and
     confirm the same if and when requested;  (ii) obtain opinions of counsel to
     the Company and updates thereof (which counsel and opinions (in form, scope
     and   substance)   shall  be  reasonably   satisfactory   to  the  Managing
     Underwriters,  if any, Special Counsel and the holders of a majority of the
     Registrable  Securities  being sold) addressed to each of the  underwriters
     covering  the  matters   customarily   covered  in  opinions  requested  in
     underwritten  offerings  and  such  other  matters  as  may  be  reasonably
     requested by such Special Counsel and Managing  Underwriters;  (iii) obtain
     "comfort" letters and updates thereof from the independent certified public
     accountants of the Company (and, if necessary,  any other certified  public
     accountants of any subsidiary of the Company or any business acquired or to
     be acquired by the Company for which  financial  statements  and  financial
     data is, or is required to be,  included  in the  Registration  Statement),
     addressed to each of the Managing Underwriters,  if any, such letters to be
     in customary form and covering matters of the type  customarily  covered in
     "comfort"  letters in  connection  with  Underwritten  Offerings;  and (iv)
     deliver such documents and  certificates as may be reasonably  requested by
     the holders of a majority of the  Registrable  Securities  being sold,  the
     Special  Counsel and the  Managing  Underwriters,  if any, to evidence  the
     continued validity of the representations and warranties of the Company and
     its  subsidiaries  made  pursuant  to  clause  (i)  above  and to  evidence
     compliance  with any  customary  conditions  contained in the  underwriting
     agreement or other agreement entered into by the Company.

                  (l)  If  requested  in  connection   with  a  disposition   of
     Registrable Securities pursuant to a Registration Statement, make available
     for inspection by a representative of the holders of Registrable Securities
     being sold, any Managing  Underwriter  participating  in any disposition of
     Registrable Securities,  if any, and any attorney or accountant retained by
     such selling holders or underwriter, financial and other records, pertinent
     corporate documents and properties of the Company and its subsidiaries, and
     cause the  executive  officers,  directors and employees of the Company and
     its subsidiaries to supply all information reasonably requested by any such
     representative,  Managing Underwriter, attorney or accountant in connection
     with such  disposition;  subject to reasonable  written  assurances by each
     such  person that such  information  will only be used in  connection  with
     matters relating to such Registration Statement.

                  (m) Comply with all  applicable  rules and  regulations of the
     SEC and make generally available to its security holders earning statements
     (which need not be audited)  satisfying  the provisions of Section 11(a) of
     the Securities Act and Rule 158 thereunder (or any similar rule promulgated
     under  the  Securities  Act) no  later  than 45 days  after  the end of any
     12-month  period (or 90 days after the end of any  12-month  period if such
     period is a fiscal year) (i) commencing at the end of any fiscal quarter in
     which Registrable  Securities are sold to underwriters in a firm commitment
     or best efforts underwritten offering, and (ii) if not sold to underwriters
     in such an  offering,  commencing  on the  first  day of the  first  fiscal
     quarter  of  the  Company   commencing   after  the  effective  date  of  a
     Registration Statement, which statements shall cover said 12-month periods.

                  (n)  Cooperate   with  the  selling   holders  of  Registrable
     Securities  to   facilitate   the  timely   preparation   and  delivery  of
     certificates representing Registrable Securities to be sold and not bearing
     any restrictive  legends;  and enable such Registrable  Securities to be in
     such  denominations and registered in such names as the selling holders may
     request.

                  (o) Use all commercially  reasonable best efforts to provide a
     CUSIP number for the  Registrable  Securities  not later than the effective
     date of the registration.

                  (p)  Cause  all   Registrable   Securities   covered   by  the
     Registration  Statement  to  be  listed  on  each  securities  exchange  or
     quotation  system on which the  Company's  Common  Stock is then  listed no
     later than the date the Registration  Statement is declared  effective and,
     in connection  therewith,  to the extent  applicable,  to make such filings
     under the Exchange  Act (e.g.,  the filing of a  Registration  Statement on
     Form 8-A) and to have such filings declared effective thereunder.

                  (q)  Cooperate  and assist in any filings  required to be made
     with the National Association of Securities Dealers, Inc.

                  (r) Provide and cause to be  maintained  a transfer  agent and
     registrar  for all  Registrable  Securities  covered  by such  registration
     statement  from and after a date not later than the effective  date of such
     Registration Statement.


                                    ARTICLE V

                              HOLDER'S OBLIGATIONS

                  SECTION 5.1.  Holder's Obligations.

                  (a) Each holder of Registrable  Securities agrees, by becoming
     an owner or transferee  of any  Registrable  Securities,  that no holder of
     Registrable  Securities  shall be entitled to sell any of such  Registrable
     Securities pursuant to a Registration  Statement or to receive a Prospectus
     relating  thereto,  unless such holder has  furnished  the Company with any
     applicable  notice  required  pursuant to Article 2 hereof  (including  the
     information  required to accompany  such notice)  and,  promptly  after the
     Company's  request,  such other  information  regarding such holder and the
     distribution of such Registrable Securities as the Company may from time to
     time reasonably request. The Company may exclude from such registration the
     Registrable  Securities of any holder who does not furnish such information
     provided above for so long as such  information  is not so furnished.  Each
     holder of Registrable  Securities as to which any Registration Statement is
     being effected  agrees  promptly to furnish to the Company all  information
     required  to be  disclosed  in  order to make  the  information  previously
     furnished  to the  Company by such holder not  misleading.  Any sale of any
     Registrable  Securities by any holder shall constitute a representation and
     warranty by such holder  that the  information  relating to such holder and
     its plan of  distribution  is as set forth in the  Prospectus  delivered by
     such holder in connection with such disposition,  that such Prospectus does
     not as of the time of such sale contain any untrue  statement of a material
     fact  relating  to such  holder or its plan of  distribution  and that such
     Prospectus  does not as of the time of such sale omit to state any material
     fact relating to such holder or its plan of distribution  necessary to make
     the  statements in such  Prospectus,  in light of the  circumstances  under
     which they were made, not misleading.

                  (b) The Company  agrees (x) that if any holder of  Registrable
     Securities  shall  send a written  notice  to the  Company  of an  intended
     distribution  of  Registrable   Securities  under  the  Shelf  Registration
     pursuant to Section 2.1(d) or the Demand  Registration  pursuant to Section
     2.2, the Company  shall not sell,  make any short sale of, loan,  grant any
     option for the purchase of,  effect any public sale or  distribution  of or
     otherwise dispose of its equity  securities or securities  convertible into
     or exchangeable or exercisable for any of such securities during the period
     from first day of the  applicable  Selling Period until the date that is 90
     days after the date when such holder shall have made such  distribution  of
     Registrable Securities under the Shelf Registration or Demand Registration,
     as the case may be, as the holder or Managing  Underwriter  (in the case of
     an Underwritten  Offering) shall advise the Company (provided,  that if the
     holder or Managing Underwriter shall fail to advise the Company of any such
     date prior to the end of the applicable  Selling Period,  such period shall
     end on the last day of the applicable  Selling Period),  except (i) as part
     of such registration,  (ii) pursuant to registrations on Form S-4 or S-8 or
     any successor or similar  forms thereto or (iii) as otherwise  permitted by
     the Managing  Underwriter  of such  offering  (if any),  and (y) to use all
     commercially  reasonable  best  efforts to cause each  holder of its equity
     securities  or  any  securities   convertible   into  or   exchangeable  or
     exercisable  for any of such  securities,  in each case  purchased from the
     Company  at any time  after  the date of this  Agreement  (other  than in a
     public  offering) to agree not to sell, make any short sale of, loan, grant
     any option for the purchase of, effect any public sale or  distribution  of
     or otherwise  dispose of such securities  during such period except as part
     of such underwritten registration;  provided, that no holder of Registrable
     Securities  included in any underwritten  registration shall be required to
     make any  representations  or warranties to the Company or the underwriters
     other than  representations  and warranties  regarding such holder and such
     holder's intended method of distribution.

              (c)  During  any  Selling  Period  (other  than  during a Deferral
     Period),  immediately  upon the existence of any fact or the  occurrence of
     any event as a result of which a Registration  Statement  shall contain any
     untrue  statement  of a material  fact or omit to state any  material  fact
     required to be stated therein or necessary to make the  statements  therein
     not  misleading,  or a Prospectus  shall contain any untrue  statement of a
     material  fact or omit to state any  material  fact  required  to be stated
     therein or necessary to make the  statements  therein,  in the light of the
     circumstances  under  which  they were  made,  not  misleading,  upon being
     notified  by the  Company  promptly  discontinue  use of such  Registration
     Statement until the Company in accordance  with its obligations  under this
     Agreement  prepares and files an amendment or  post-effective  amendment to
     each  Registration  Statement or a supplement to the related  Prospectus or
     any document  incorporated  therein by reference or file any other required
     document (such as a Current Report on Form 8-K) that would be  incorporated
     by  reference  into the  Registration  Statement  so that the  Registration
     Statement shall not contain any untrue statement of a material fact or omit
     to state any material  fact  required to be stated  therein or necessary to
     make the statements therein not misleading, and so that the Prospectus will
     not contain any untrue  statement  of a material  fact or omit to state any
     material  fact or omit to state any  material  fact  required  to be stated
     therein or necessary to make the  statements  therein,  in the light of the
     circumstances  under which they were made,  not  misleading,  as thereafter
     delivered  to the  purchasers  of the  Registrable  Securities  being  sold
     thereunder.

              (d) Deliver to prospective  investors and investors  copies of the
     Prospectus  or  Prospectuses   relating  to  such  Registrable   Securities
     (including  each  preliminary  prospectus)  and any amendment or supplement
     thereto  in  accordance  with  the  Securities  Act  and  applicable  state
     securities laws.



                                   ARTICLE VI

                                    EXPENSES

                  SECTION  6.1  Registration  Expenses.  All fees  and  expenses
     incident to the Company's  performance of or compliance with this Agreement
     shall  be  borne  by the  Company  whether  or not any of the  Registration
     Statements become effective.  Such fees and expenses shall include, without
     limitation,  (i) all  registration  and  filing  fees  (including,  without
     limitation,  fees and expenses  (x) with respect to filings  required to be
     made with the National Association of Securities Dealers, Inc. and (y) with
     respect to compliance with federal  securities or Blue Sky laws (including,
     without limitation, fees and disbursements of Special Counsel in connection
     with Blue Sky  qualifications  of the  Registrable  Securities laws of such
     jurisdictions  as the  Managing  Underwriters,  if  any,  or  holders  of a
     majority of the Registrable  Securities  being sold may  designate)),  (ii)
     printing  expenses  (including,  without  limitation,  expenses of printing
     certificates for Registrable Securities in a form eligible for deposit with
     The Depositary  Trust Company and of printing  Prospectuses if the printing
     of  Prospectuses  is requested  by the Special  Counsel or the holders of a
     majority  of  the  Registrable  Securities  included  in  any  Registration
     Statement),   (iii)  messenger,   telephone  and  delivery  expenses,  (iv)
     reasonable  fees and  disbursements  of  counsel  for the  Company  and the
     Special  Counsel  in  connection  with  the  Registration,   (v)  fees  and
     disbursements of all independent  certified public  accountants  (including
     the  expenses of any special  audit and  "comfort"  letters  required by or
     incident to such  performance) and (vi) Securities Act liability  insurance
     obtained by the Company in its sole  discretion.  In addition,  the Company
     shall  pay  its  internal  expenses  (including,  without  limitation,  all
     salaries and expenses of its officers  and  employees  performing  legal or
     accounting  duties),  the expense of any annual audit or interim  review of
     financial statements, the fees and expenses incurred in connection with the
     listing of the  securities to be registered on any  securities  exchange on
     which similar securities issued by the Company are then listed and the fees
     and  expenses of any person,  including  special  experts,  retained by the
     Company. Notwithstanding the provisions of this Section 6.1, each seller of
     Registrable  Securities shall pay all  registration  expenses to the extent
     the Company is prohibited by applicable Blue Sky laws from paying for or on
     behalf of such seller of Registrable Securities.


                                   ARTICLE VII

                                 INDEMNIFICATION

                  SECTION 7.1  Company  Indemnification.  The Company  agrees to
     indemnify  and hold harmless each holder of  Registrable  Securities  whose
     Registrable  Securities  are  covered by any  Registration  Statement,  its
     directors  and officers and each other  Person,  if any, who controls  such
     holder  within the  meaning of the  Securities  Act,  against  any  losses,
     claims,  damages  or  liabilities,  joint or  several,  to  which  any such
     indemnified party may become subject under the Securities Act or otherwise,
     insofar as such  losses,  claims,  damages or  liabilities  (or  actions or
     proceedings, whether commenced or threatened, in respect thereof) arise out
     of or are based upon any untrue  statement or alleged  untrue  statement of
     any material fact contained in any Registration  Statement under which such
     securities  were  registered  under the  Securities  Act,  any  preliminary
     Prospectus,  final Prospectus or summary Prospectus  contained therein,  or
     any amendment or supplement thereto, or any omission or alleged omission to
     state therein a material fact required to be stated therein or necessary to
     make the statements therein not misleading,  and the Company will reimburse
     each such indemnified party for any legal or any other expenses  reasonably
     incurred by them in  connection  with  investigating  or defending any such
     loss,  claim,  liability,  action or proceeding;  provided that the Company
     shall  not be liable in any such  case to the  extent  that any such  loss,
     claim,  damage,  liability (or action or proceeding in respect  thereof) or
     expense  arises  out of or is based  upon an untrue  statement  or  alleged
     untrue statement or omission or alleged omission made in such  Registration
     Statement,  any such  preliminary  Prospectus,  final  Prospectus,  summary
     Prospectus, amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company by or on behalf of such holder
     specifically for use in the preparation  thereof. In addition,  the Company
     shall indemnify any underwriter of such offering and each other Person,  if
     any, who controls any such underwriter within the meaning of the Securities
     Act in substantially  the same manner and to substantially  the same extent
     as the indemnity herein provided to each Indemnified  Party. Such indemnity
     shall remain in full force and effect regardless of any investigation  made
     by or on behalf of such holder or any such director,  officer,  underwriter
     or controlling  person and shall survive the transfer of such securities by
     such holder.

                  SECTION 7.2 Seller Indemnification. Each prospective seller of
     Registrable   Securities  hereunder  severally,   and  not  jointly,  shall
     indemnify  and hold  harmless (in the same manner and to the same extent as
     set forth in Section 7.1) the Company,  each director of the Company,  each
     officer of the Company and each other  person,  if any,  who  controls  the
     Company  within the  meaning of the  Securities  Act,  with  respect to any
     statement or alleged statement in or omission or alleged omission from such
     Registration  Statement,  any preliminary  Prospectus,  final Prospectus or
     summary  Prospectus  contained  therein,  or any  amendment  or  supplement
     thereof,  if such  statement  or alleged  statement  or omission or alleged
     omission  was  made  in  reliance  upon  and  in  conformity  with  written
     information  furnished  to the  Company  by or on  behalf  of  such  seller
     specifically  for use in the  preparation of such  Registration  Statement,
     preliminary Prospectus,  final Prospectus,  summary Prospectus or amendment
     or supplement.  Any such  indemnity  shall remain in full force and effect,
     regardless of any investigation  made by or on behalf of the Company or any
     such director, officer or controlling person and shall survive the transfer
     of such  securities by such seller.  The amount payable by any  prospective
     seller of Registrable  Securities with respect to the  indemnification  set
     forth in this Section 7.2 in  connection  with any offering of  Registrable
     Securities  will  not  exceed  the  amount  of the  gain  realized  by such
     prospective seller pursuant to such offering.

                  SECTION 7.3 Indemnification Procedure.  Promptly after receipt
     by an  indemnified  party of notice of the  commencement  of any  action or
     proceeding  involving a claim referred to in the preceding sections of this
     Article VII, such indemnified  party will, if a claim in respect thereof is
     to be made against an indemnifying party, give written notice to the latter
     of the  commencement  of such  action;  provided  that the  failure  of any
     indemnified  party to give notice as provided  herein shall not relieve the
     indemnifying  party of its obligations under the preceding sections of this
     Article VII, except to the extent that the  indemnifying  party is actually
     prejudiced  by such  failure  to give  notice.  In case any such  action is
     brought against an indemnified  party,  unless in such indemnified  party's
     reasonable  judgment a conflict of interest  between such  indemnified  and
     indemnifying  parties may exist in respect of such claim,  the indemnifying
     party  shall be  entitled  to  participate  in and to  assume  the  defense
     thereof,  jointly with any other indemnifying party similarly notified,  to
     the extent that the  indemnifying  party may wish, with counsel  reasonably
     satisfactory  to  such  indemnified   party,  and  after  notice  from  the
     indemnifying  party to such indemnified  party of its election so to assume
     the defense  thereof,  the  indemnifying  party shall not be liable to such
     indemnified party for any legal or other expenses  subsequently incurred by
     the latter in connection with the defense  thereof.  No indemnifying  party
     shall,  without the consent of the indemnified  party,  consent to entry of
     any judgment or enter into any settlement of any such action which does not
     include as an  unconditional  term  thereof  the giving by the  claimant or
     plaintiff  to such  indemnified  party of a release  from all  liability in
     respect to such claim or litigation.  No indemnified party shall consent to
     entry of any judgment or enter into any  settlement  of any such action the
     defense of which has been  assumed by an  indemnifying  party  without  the
     consent of such indemnifying party.

                  SECTION 7.4  Remedies.

                  (a) If the indemnification provided for in Section 7.1 or 7.2,
     as the case may be, is unavailable  to an  indemnified  party in respect of
     any expense,  loss, claim,  damage or liability  referred to therein,  then
     each indemnifying  party, in lieu of indemnifying  such indemnified  party,
     shall contribute to the amount paid or payable by such indemnified party as
     a result of such  expense,  loss,  claim,  damage or liability  (i) in such
     proportion as is appropriate to reflect the relative  benefits  received by
     the Company on the one hand and the holder or underwriter,  as the case may
     be, on the other from the  distribution  of the  Registrable  Securities or
     (ii) if the  allocation  provided by clause (i) above is not  permitted  by
     applicable  law, in such  proportion as is  appropriate to reflect not only
     the relative benefits referred to in clause (i) above but also the relative
     fault of the Company on the one hand and of the holder or  underwriter,  as
     the case  may be,  on the  other  in  connection  with  the  statements  or
     omissions  which resulted in such expense,  loss,  damage or liability,  as
     well as any other relevant equitable considerations.  The relative fault of
     the Company on the one hand and of the holder or  underwriter,  as the case
     may be, on the other  shall be  determined  by  reference  to,  among other
     things,  whether the untrue or alleged untrue  statement of a material fact
     or omission to state a material fact relates to information supplied by the
     Company,  by the holder or by the underwriter and parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission;  provided, that the foregoing contribution agreement
     shall not inure to the benefit of any indemnified party if  indemnification
     would be  unavailable  to such  indemnified  party by reason of the proviso
     contained in the first sentence of subdivision (a) of this Section 7.4, and
     in no event shall the  obligation of any  indemnifying  party to contribute
     under this subdivision (d) exceed the amount that such  indemnifying  party
     would  have  been  obligated  to  pay  by  way  of  indemnification  if the
     indemnification  provided for under subdivisions (a) or (b) of this Section
     2.5 had been available under the circumstances.

                  (b) The  Company  and the  holders of  Registrable  Securities
     agree that it would not be just and equitable if  contribution  pursuant to
     this  Section  7.4  were  determined  by pro rata  allocation  (even if the
     holders and any  underwriters  were treated as one entity for such purpose)
     or by any other  method of  allocation  that does not take  account  of the
     equitable considerations referred to in the immediately preceding paragraph
     (a). The amount paid or payable by an indemnified  party as a result of the
     losses,  claims,  damages and  liabilities  referred to in the  immediately
     preceding paragraph shall be deemed to include,  subject to the limitations
     set forth above,  any legal or other expenses  reasonably  incurred by such
     indemnified  party in connection with  investigating  or defending any such
     action or claim.

                  (c)  Notwithstanding the other provisions of this Section 7.4,
     no holder of  Registrable  Securities or  underwriter  shall be required to
     contribute  any  amount in excess of the amount by which (i) in the case of
     any  such  holder,  the  gain  realized  by such  holder  from  the sale of
     Registrable  Securities  or (ii) in the case of an  underwriter,  the total
     price at which the Registrable  Securities  purchased by it and distributed
     to the public were  offered to the public  exceeds,  in any such case,  the
     amount of any damages that such holder or  underwriter  has otherwise  been
     required to pay by reason of such  untrue or alleged  untrue  statement  or
     omission.  No Person  guilty of  fraudulent  misrepresentation  (within the
     meaning of  Section  11(f) of the  Securities  Act)  shall be  entitled  to
     contribution  from  any  Person  who was  not  guilty  of  such  fraudulent
     misrepresentation.

                                     REPORTS

                  SECTION 8.1 Rule 144; Rule 144A; Form S-3.

                  (a) The Company will file all reports  required to be filed by
     it  under  the  Securities  Act and the  Exchange  Act  and the  rules  and
     regulations adopted by the SEC thereunder and will take such further action
     as any holder of Registrable  Securities may reasonably request, all to the
     extent required from time to time to enable such holder to sell Registrable
     Securities  without  registration  under  the  Securities  Act  within  the
     limitation of the exemptions  provided by (a) Rule 144 under the Securities
     Act, as such Rule may be amended from time to time, or (b) any similar rule
     or regulation  hereafter adopted by the SEC. Upon the request of any holder
     of  Registrable  Securities,  the  Company  will  deliver to such  holder a
     written statement as to whether it has complied with such requirements. The
     Company  further  covenants  that it will  cooperate  with  any  holder  of
     Registrable  Securities  and take  such  further  reasonable  action as any
     holder of Registrable Securities may reasonably request (including, without
     limitation,  making such reasonable  representations as any such holder may
     reasonably request), all to the extent required from time to time to enable
     such holder to sell Registrable  Securities without  registration under the
     Securities Act within the limitation of the exemptions provided by Rule 144
     and Rule 144A, as applicable, under the Securities Act.

                  (b) For so long as any shares of  Registrable  Securities  are
     Restricted  Securities  within  the  meaning  of Rule  144(a)(3)  under the
     Securities Act, the Company covenants and agrees that it shall,  during any
     period in which it is not  subject to  Section 13 or 15(d) of the  Exchange
     Act, make available to any holder of  Registrable  Securities in connection
     with the sale by such holder of Registrable  Securities and any prospective
     purchaser of Registrable  Securities  from such, in each case upon request,
     the  information  specified  in, and  meeting  the  requirements  of,  Rule
     144A(d)(4) under the Securities Act.

                  (c) The Company shall file the reports required to be filed by
     it under the  Exchange  Act and  shall  comply  with all other  eligibility
     requirements  for use of Form S-3 set forth in the instructions to Form S-3
     (other than Registration Requirement A.5).

                  SECTION 9.2 Binding Nature of Agreement.  This Agreement shall
     be  binding  upon and inure to the  benefit  of and be  enforceable  by the
     parties  hereto  or their  successors  in  interest,  except  as  expressly
     otherwise provided herein.

                  SECTION 9.3 Descriptive Headings.  The descriptive headings of
     the several  sections and  paragraphs  of this  Agreement  are inserted for
     reference only and shall not limit or otherwise affect the meaning hereof.

                  SECTION 9.4 Specific Performance.  Without limiting the rights
     of each  party  hereto to  pursue  all other  legal  and  equitable  rights
     available  to such party for the other  parties'  failure to perform  their
     obligations under this Agreement,  the parties hereto acknowledge and agree
     that  the  remedy  at law for any  failure  to  perform  their  obligations
     hereunder would be inadequate and that each of them, respectively, shall be
     entitled  to specific  performance,  injunctive  relief or other  equitable
     remedies in the event of any such failure.

                  SECTION 9.5  Governing  Law;  Consent to  Jurisdiction  . This
     Agreement  shall be governed by and  construed  and enforced in  accordance
     with the internal laws of the State of New York. Each of the parties hereto
     irrevocably  submits to the personal  exclusive  jurisdiction of the United
     States  District  Court  for the  Southern  District  of New  York  for the
     purposes  of any  suit,  action  or other  proceeding  arising  out of this
     Agreement  or any  transaction  contemplated  hereby  (and,  to the  extent
     permitted under applicable  rules of procedure,  agrees not to commence any
     action,  suit or proceeding  relating hereto except in such court). Each of
     the parties further agree that service of any process,  summons,  notice or
     document  hand  delivered  or sent  by  registered  mail  to  such  party's
     respective  address set forth in Section 9.1 will be  effective  service of
     process for any action,  suit or proceeding in New York with respect to any
     matters  to which it has  submitted  to  jurisdiction  as set  forth in the
     immediately preceding sentence.  Each of the parties hereto irrevocably and
     unconditionally  waive any  objection to the laying of venue of any action,
     suit or  proceeding  arising  out of  this  Agreement  or the  transactions
     contemplated  hereby in the United States  District  Court for the Southern
     District of New York, and hereby further  irrevocably  and  unconditionally
     waive and agree not to plead or claim in such court  that any such  action,
     suit  or  proceeding   brought  in  such  court  has  been  brought  in  an
     inconvenient forum.

                  SECTION  9.6  WAIVER OF JURY  TRIAL.  EACH OF  PARTIES  HERETO
     HEREBY  IRREVOCABLY  WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
     PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS
     CONTEMPLATED HEREBY.

                  SECTION  9.7   Limitations  on  Damages.   Each  party  hereto
     acknowledges  that,  except  as  provided  in this  Agreement,  no party is
     entitled to seek or recover consequential, punitive or exemplary damages in
     respect  of this  Agreement  under  any  circumstances  or for any  reason.
     Consequential  damages are, without limitation,  lost profits, lost revenue
     and the like but do not include  the actual  costs  incurred  in  obtaining
     substitute  performance  where  there  has been a  failure  to  perform  an
     obligation under any provision of this Agreement.

                  SECTION 9.8 Severability.  If any term, provision, covenant or
     restriction of this Agreement is held by a court of competent  jurisdiction
     to  be  invalid,  void  or  unenforceable,  the  remainder  of  the  terms,
     provisions,  covenants and  restrictions  of this Agreement shall remain in
     full  force  and  effect  and  shall  in no way be  affected,  impaired  or
     invalidated.  It is hereby  stipulated  and declared to be the intention of
     the parties that they would have executed the remaining terms,  provisions,
     covenants  and  restrictions  without  including  any of such  which may be
     hereafter declared invalid, void or unenforceable.

                  SECTION 9.9  Amendments  to Laws.  Any reference to a section,
     form,  rule or regulation of the Securities  Act or Exchange Act,  includes

required  to,  state  that  it  is  exercising  an  over-allotment   right  (the
"Over-Allotment  Right")  and the  number  of Shares it is  willing  to  acquire

refusal pursuant to Section 5.01(a)(i),  such Shares shall be allocated pro rata
among the Purchasing  Shareholders exercising the Over-Allotment Right up to the
maximum  amount  stated  in  such   Purchasing   Shareholder's   notices.   Such
communication  shall,  when taken in  conjunction  with the Offer,  be deemed to
constitute a valid, binding and enforceable  agreement for the sale and purchase
of the Offered Shares.

contravention of any law or agreement,  and without the need for any third party
(not including any  governmental  or regulatory  consent or approval which shall
have been  received)).  At the Offered Shares  Closing a Purchasing  Shareholder
shall pay the purchase  price for the Offered  Shares in such amount and on such
payment terms as set forth in the Offer.

price and upon other terms and  conditions  not more  favorable  to the Proposed
Transferee than those specified in the Offer. If any Offered Shares are not sold
within the sixty (60)-day period or if the terms of the Offer shall change,  the
Offered Shares shall be subject to renewed  compliance with the  requirements of
the right of first  refusal  pursuant to Section  5.01.  Any third party to whom
Shares  are  sold  shall  become a  Co-Investor  and  shall  have no  rights  or
obligations  under  this  Agreement  except as  provided  in  Sections  2.02(i),

Put/Call  Shares  and if the  price to be paid  equals  or  exceeds  the  Target
Investment  Value per Share (using the Call Rate as the discount rate) as of the
date set for payment,  then the Put/Call Shares so Transferred shall continue to
be subject to the Call Option and the purchasing  Co-Investor shall execute such
documents as are reasonably requested by TSC or its Assignee as to the existence
and  enforceability of the Call Option, and (y) if the Transfer to a Co-Investor
is a Transfer by National Union or its Permitted  Transferee of Put/Call  Shares
and if RNT consents to such Transfer and the  continuation of the Put Option and
the Call Option in writing  (which such consent shall be in the sole  discretion
of RNT and may be granted or  withheld  for any reason or no  reason),  then the
Put/Call  Shares so  Transferred  shall continue to be subject to the Put Option

                                Tag-Along Rights

     SECTION 6.01  Tag-Along  Option.  Subject to Sections 2.04 and 6.03 of this
Agreement,  if a  Shareholder  (a "Disposing  Shareholder")  (i) decides to sell
Shares and (ii)  either (x) any one or more of the other  Shareholders  have not
exercised  their right of first  refusal as provided in Article V and  purchased
the Offered  Shares or (y) the Shares in question  are not subject to Article V,
the Disposing  Shareholder  will cause the intended  purchaser of such Disposing
Shareholder's  Shares to afford to each party hereto that is a  Shareholder  for
purposes  of this  Article VI (each,  a  "Non-Exercising  Shareholder"),  at its
option,  the opportunity to sell (and will require the prospective  purchaser to
purchase) the Shares held by such remaining  Shareholders in the same proportion
to the number of shares  sought to be disposed of by the  Disposing  Shareholder
and Non-Exercising Shareholders and on the same terms and conditions as those to
be sold by the Disposing Shareholder,  and for the same consideration per share.
The   Disposing   Shareholder's   obligation   to  afford   the   Non-Exercising
Shareholders,  or cause the  Non-Exercising  Shareholders  to be  afforded,  the
opportunity  and rights set forth in this Article VI, shall be discharged if the
Non-Exercising   Shareholders   are  given  written  notice  which  allows  such
Shareholder  thirty  (30) days to elect to avail  themselves  of such  rights by
written notice to the Disposing Shareholder.  If any Non-Exercising  Shareholder
elects to not  participate  or otherwise does not  affirmatively  respond within
such thirty (30) day period, the Disposing  Shareholders and such Non-Exercising
Shareholders  who have made an  affirmative  election  to sell their  Shares may
proceed with the sale,  without regard to the  application of this Article VI to
the non-electing remaining Shareholder(s).

     SECTION 6.02 Sale to Third Party.  Any such sales shall be at not less than
the price and upon other  terms and  conditions  not more  favorable  than those
specified in the Offer.  If any such Shares are not sold within a sixty (60)-day
period from the date of the Offer,  or if the terms of the Offer  shall  change,
the Shares shall be subject to the  requirements of the tag-along right pursuant
to  Section  6.01.  Any  third  party to whom  Shares  are sold  shall  become a
Co-Investor and shall have no rights or obligations hereunder except as provided
in Sections 2.02(i), 2.03(b), 2.04 and 2.05, provided, however, that if the sale
to a third  party is a sale by National  Union or its  Permitted  Transferee  of
Put/Call  Shares  and if the  price  per  share to be paid  exceeds  the  Target
Investment Value per Share (using the Call Rate as the discount rate),  then the

     SECTION 7.07 Subscription Rights.

          (a) If the Board of  Directors  of the  Company  shall  authorize  the
     issuance  of New  Securities,  then,  prior to each  such  issuance  of New
     Securities,  the Company shall offer to each  Shareholder and its Permitted
     Transferees a Pro Rata Share of such New Securities.

          (b) Any offer of New Securities  made to any  Shareholder or Permitted
     Transferee  under this Section 7.07 shall be made by notice in writing (the
     "Subscription Notice") at least ten (10) Business Days prior to the date on
     which the meeting of the Board is held to  authorize  the  issuance of such
     New Securities.  The Subscription  Notice shall set forth (i) the number of
     New Securities  proposed to be issued and the terms of such New Securities,
     (ii) the  consideration  (or manner of determining the  consideration),  if
     any, for which such New  Securities are proposed to be issued and the terms
     of payment,  (iii) the number of New Securities offered to each Shareholder
     and Permitted  Transferee in compliance with the provisions of this Section
     7.07 and (iv) the  proposed  date of issuance of such New  Securities.  Not
     later than twenty (20)  Business  Days after its receipt of a  Subscription
     Notice, each Shareholder and Permitted  Transferee shall notify the Company
     in writing  whether  it elects to  purchase  all or any  portion of the New
     Securities  offered  to  it  pursuant  to  the  Subscription  Notice.  If a
     Shareholder  or Permitted  Transferee  shall elect to purchase any such New
     Securities,  the New  Securities  which it shall have  elected to  purchase
     shall be issued and sold to such person by the Company at the same time and
     on the same terms and  conditions as the New Securities are issued and sold
     to third  parties.  If, for any reason,  the issuance of New  Securities to
     third  parties  is not  consummated,  the  right  of the  Shareholders  and
     Permitted  Transferees to their respective Pro Rata Shares of such issuance
     shall lapse,  subject to their ongoing  subscription  right with respect to
     issuances of New Securities at later dates or times.

          (c) The Company  represents  and  covenants  to each  Shareholder  and
     Permitted  Transferee  that  (i)  upon  issuance,  all  the  shares  of New
     Securities  sold to such person pursuant to this Section 7.07 shall be duly
     authorized,  validly  issued,  fully  paid  and  nonassessable  and will be
     approved (if outstanding  securities of the Company of the same type are at
     the time already  approved) for listing on the American  Stock  Exchange or
     for quotation or listing on the principal trading market for the securities
     of the Company at the time of issuance,  (ii) upon delivery of such shares,
     they shall be free and clear of all claims, Liens,  encumbrances,  security
     interests  and  charges  of any  nature  and  shall not be  subject  to any
     preemptive  right of any stockholder of the Company and (iii) in connection
     with  any such  issuance,  the  Company  shall  take  such  actions  as are
     specified in Section  3.01(q) of the  Securities  Purchase  Agreement  with
     respect to such shares.
