               including, without limitation, fees and disbursements of
               counsel for the Holders if such counsel is not also counsel
               for the Company, printing expenses and marketing expenses. 

                    "Shares" shall mean the 133,333 shares of Common Stock
               issued to or for the benefit of the Holders on the date
               hereof, as that number shall be adjusted pursuant to the
               Stock Purchase Agreement, and any shares of Common Stock
               issued in respect thereof in connection with stock splits,
               stock dividends or distributions, or combinations or similar

          Securities Act.

               3.   Restrictive Legends.

                    (a)  Each certificate representing Shares shall (unless
          otherwise permitted by subsection (c) of this Section 3 or
          Section 4) be stamped with the following legend:



                                        - 2 -



               THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
               BEEN ISSUED PURSUANT TO AN EXEMPTION FROM AND HAVE NOT
               BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT
               OF 1933.  SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED
               OR PLEDGED IN THE ABSENCE OF SUCH REGISTRATION OR
               UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL
               (WHICH MAY BE COUNSEL FOR THE COMPANY) REASONABLY
               ACCEPTABLE TO IT STATING THAT SUCH REGISTRATION IS NOT
               REQUIRED. 

                    (b)  Each certificate representing Shares shall also be
          stamped with the following legend:

               THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE
               SUBJECT TO THE TERMS AND CONDITIONS OF AN AGREEMENT
               BETWEEN CERTAIN STOCKHOLDERS AND THE CORPORATION WHICH
               INCLUDES RESTRICTIONS ON CERTAIN SALES OF THE
               SECURITIES.  COPIES OF THE AGREEMENT MAY BE OBTAINED
               UPON WRITTEN REQUEST TO THE SECRETARY OF THE
               CORPORATION.

                    (c)  Each Holder consents to the Company's making a
          notation on its records and giving instructions to any transfer
          agent of the Company in order to implement the restrictions on
          transfer established in this Agreement.  The legend placed on any
          certificate pursuant to Section 3(a) and any notations or
          instructions with respect to the Restricted Shares represented by
          such certificate will be promptly removed, and the Company will
          promptly issue a certificate without such legend to the Holder of
          such Restricted Shares (i) if such Restricted Shares are
          registered under the Securities Act (but only in connection with
          the actual sale of such securities) and a prospectus meeting the
          requirements of Section 10 of the Securities Act is available or
          (ii) if the Holder thereof satisfies the requirements of Rule
          144(k) and, where reasonably determined necessary by the Company,
          provides the Company with an opinion of counsel for the Holder of
          the Shares, both such counsel and such opinion being reasonably
          satisfactory to the Company, to the effect that (A) the Holder
          meets the requirements of Rule 144(k) or (B) a public sale,
          transfer or assignment of the Shares may be made without
          registration.

               4.   Notice of Proposed Transfers.  The holder of each
          certificate representing Restricted Shares by acceptance thereof
          agrees to comply in all respects with the provisions of this
          Section 4.  Prior to any proposed sale, assignment, transfer or
          pledge of any Restricted Shares, unless there is in effect a
          registration statement under the Securities Act covering the
          proposed transfer, the Holder thereof shall notify the Company in
          writing of such Holder's intention to effect such sale,
          assignment, transfer or pledge and the intended manner and
          circumstances thereof in reasonable detail.  If requested by the

                                        - 3 -



          Company, any such notice shall be accompanied at such Holder's
          expense by a written opinion of legal counsel who is, and whose
          legal opinion shall be, reasonably satisfactory to the Company,
          addressed to the Company, to the effect that the proposed
          transfer of Restricted Shares may be effected without
          registration under the Securities Act, and by such certificates
          and other information as the Company may reasonably require to
          confirm such opinion, whereupon the Holder of such Restricted
          Shares shall be entitled to transfer such Restricted Shares in
          the manner contemplated by such opinion.  Each certificate
          evidencing the Restricted Shares transferred as above provided
          shall bear, except if such transfer is made pursuant to Rule 144,
          the appropriate restrictive legend set forth in Section 3(a)
          above, except that such certificate shall not bear such
          restrictive legend if in the opinion of counsel for such Holder
          and the Company such legend is not required in order to establish
          compliance with any provisions of the Securities Act.  So long as
          such restrictive legend shall be required to remain on any such
          certificates, the transfer of the Restricted Shares represented
          thereby shall be conditioned upon the transferee thereof becoming
          a party hereto (except that such transferee shall have no rights
          under Sections 5 or 12 hereof unless the transferee is a Holder).

               5.   Company Registration.

                    (a)  Notice of Registration.  If, at any time or from
          time to time, the Company shall determine to register any of its
          Common Stock, either for its own account or the account of a
          security holder or holders for distribution pursuant to an
          underwritten offering, the Company will (i) promptly give to each
          Holder written notice thereof, and (ii) include in such
          registration (and any related qualification under blue sky laws
          or other compliance), subject to Section 5(b), all the
          Registrable Shares held by such Holder if so requested in writing
          by the Holder within 30 days after receipt of such written notice
          from the Company.

                    (b)  Underwriting.  The right of the Holders to
          registration pursuant to this Section 5 shall be conditioned upon
          the Holders' participation in such underwriting and the inclusion
          of all the Registrable Shares held by such Holders in the
          underwriting to the extent provided herein.  The Holder,
          proposing to distribute all the Registrable Shares held by such
          Holder through such underwriting shall (together with the Company
          and the other holders distributing shares of Common Stock through
          such underwriting), if required by the managing underwriter of
          such offering, enter into an underwriting agreement in customary
          form with the managing underwriter selected for such underwriting
          by the Company (or by the holders who have demanded such
          registration), and shall provide to the Company upon written
          request such information referenced in Section 5(d) hereof as may
          be specified in such request.  Notwithstanding any other

                                        - 4 -



          provision of this Section 5, if the managing underwriter in its
          sole discretion determines that marketing factors require a
          limitation of the number of shares to be underwritten, the
          managing underwriter may limit the Registrable Shares to be
          included in such registration.  The Company shall so advise all
          Holders and the other holders distributing their securities
          through such underwriting pursuant to piggyback registration
          rights similar to this Section 5, and the number of Registrable
          Shares and other securities that may be included in the
          registration and underwriting by such Holders and such other
          holders shall be reduced by the number of shares determined by
          the managing underwriter not to be included in such registration,
          such cutback to be allocated among all Holders and such other
          holders in proportion, as nearly as practicable, to the
          respective amounts of Registrable Shares held by such Holders and
          such other securities by such other holders.  If any Holder
          disapproves of the terms of any such underwriting, such Holder
          may elect to withdraw therefrom by written notice to the Company
          and the managing underwriter.

                    (c)  Right to Terminate Registration.  The Company
          shall have the right to terminate or withdraw any registration
          under this Section 5 prior to the effectiveness of such
          registration whether or not the Holders have elected to include
          securities in such registration.

               6.   Expenses of Registration.  All Registration Expenses
          incurred in connection with any registration pursuant to Section
          5 shall be borne by the Company.  All Selling and Distribution
          Expenses attributable to the Registrable Shares registered on
          behalf of the Holders shall be borne by the Holders of the
          Registrable Shares included in such registration pro rata on the
          basis of the number of Registrable Shares so registered.

               7.   Indemnification.

                    (a)  The Company will indemnify each Holder, each of
          its officers, directors, employees and agents and each person
          controlling such Holder within the meaning of Section 15 of the
          Securities Act, with respect to which registration, qualification
          or compliance has been effected pursuant to this Agreement,
          against all expenses, claims, losses, damages or liabilities (or
          actions in respect thereof), including any of the foregoing
          incurred in settlement of any litigation, commenced or
          threatened, arising out of or based on any untrue statement (or
          alleged untrue statement) of a material fact contained in any
          registration statement, prospectus, offering circular or other
          document, or any amendment or supplement thereto, incident to any
          such registration, qualification or compliance, or any omission
          (or alleged omission) to state therein a material fact required
          to be stated therein or necessary to make the statements therein,
          in the light of the circumstances in which they were made, not

                                        - 5 -



          misleading, or any violation by the Company of any rule or
          regulation promulgated under the Securities Act or any other
          federal, state or common law rule or regulation applicable to the
          Company in connection with any such registration, qualification
          or compliance, and the Company will reimburse each such Holder,
          each of its officers, directors, employees and agents and each
          person controlling such Holder for any legal and any other
          expenses reasonably incurred in connection with investigating,
          preparing or defending any such claim, loss, damage, liability or
          action, provided that the Company will not be liable in any such
          case to the extent that any such claim, loss, damage, liability
          or expense arises out of or is based on any untrue statement or
          omission or alleged untrue statement or omission made in reliance
          upon and in conformity with any written information furnished to
          the Company pursuant to an instrument duly executed by such
          Holder or controlling person and stated to be specifically for
          use therein.

                    (b)  Each Holder will, if Registrable Shares held by
          such Holder are included in the securities as to which such
          registration, qualification or compliance is being effected,
          indemnify the Company, each of its directors and officers, each
          underwriter, if any, of the Company's securities covered by such
          a registration statement, each person who controls the Company or
          such underwriter within the meaning of Section 15 of the
          Securities Act, and each other such Holder, each of its officers
          and directors and each person controlling such Holder within the
          meaning of Section 15 of the Securities Act, against all claims,
          losses, damages and liabilities (or actions in respect thereof)
          arising out of or based on any untrue statement (or alleged
          untrue statement) of a material fact contained in any such
          registration statement, prospectus, offering circular or other
          document, 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 will reimburse
          the Company, such Holders, such directors, officers, persons,
          underwriters or control persons for any legal or any other
          expenses reasonably incurred in connection with investigating or
          defending any such claim, loss, damage, liability or action, in
          each case to the extent, but only if and to the extent, that such
          untrue statement (or alleged untrue statement) or omission (or
          alleged omission) is made in such registration statement,
          prospectus, offering circular or other document in reliance upon
          and in conformity with any written information furnished to the
          Company pursuant to an instrument duly executed by such Holder
          and stated to be specifically for use therein.

                    (c)  Each party entitled to indemnification under this
          Section 7 (the "Indemnified Party") shall give written notice to
          the party required to provide indemnification (the "Indemnifying
          Party") promptly after such Indemnified Party has actual
          knowledge of any claim as to which indemnity may be sought, and

                                        - 6 -



          shall permit the Indemnifying Party to assume the defense of any
          such claim or any litigation resulting therefrom, provided that
          counsel for the Indemnifying Party, who shall conduct the defense
          of such claim or litigation, shall be approved by the Indemnified
          Party (whose approval shall not unreasonably be withheld), and
          the Indemnified Party may participate in such defense at such
          party's expense, and provided further that the failure of any
          Indemnified Party to give notice as provided herein shall not
          relieve the Indemnifying Party of its obligations under this
          Agreement unless, but only to the extent that, the failure to
          give such notice is actually prejudicial to an Indemnifying
          Party's ability to defend such action.  No Indemnifying Party, in
          the defense of any such claim or litigation, shall, except with
          the consent of each Indemnified Party, consent to entry of any
          judgment or enter into any settlement 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.

                    (d)  In order to provide for just and equitable
          contribution to joint liability under the Securities Act in any
          case in which any Holder of Registrable Shares exercising rights
          under this Agreement, or any controlling person of any such
          Holder, makes a claim for indemnification pursuant to this
          Section 7 but it is judicially determined (by the entry of a
          final judgment or decree by a court of competent jurisdiction and
          the expiration of time to appeal or the denial of the last right
          of appeal) that such indemnification may not be enforced in such
          case notwithstanding the fact that this Section 7 provides for
          indemnification in such case, then, the Company and such Holder
          will contribute to the aggregate losses, claims, damages or
          liabilities to which they may be subject (after contribution from
          others) in such proportion so that such Holder is responsible for
          the portion represented by the percentage that the public
          offering price of its Registrable Shares offered by the
          registration statement bears to the public offering price of all
          Shares offered by such registration statement; and the Company is
          responsible for the remaining portion not payable by any other
          Holder or holder; provided, however, that, in any such case, (A)
          no such Holder will be required to contribute any amount in
          excess of the public offering price of all such Registrable
          Shares offered by it pursuant to such registration statement; and
          (B) no person guilty of fraudulent misrepresentation (within the
          meaning of Section 11(f) of the Securities Act) will be entitled
          to contribution from any person who was not guilty of such
          fraudulent misrepresentation.

               8.   Obligations of the Company.  Whenever required under
          this Agreement to effect the registration of any Registrable
          Shares, the Company shall, as expeditiously as reasonably
          possible:


                                        - 7 -


                    (a)  Furnish to the Holders whose Registrable Shares
          have been included in a registration statement such numbers of
          copies of the registration statement and all amendments thereto,
          any prospectus included in such registration statement, including
          any preliminary prospectus, in conformity with the requirements
          of the Securities Act, and such other documents as they may
          reasonably request in order to facilitate the disposition of
          Registrable Shares owned by them.

                    (b)  Enter into and perform its obligations under an
          underwriting agreement, in usual and customary form, with the
          managing underwriter of such offering.  Each Holder participating
          in such underwriting shall also enter into and perform its
          obligations under such an agreement.

               9.   Securities Law Compliance.  The Holders of Registrable
          Shares included in any registration pursuant to this Agreement
          covenant that they will comply with the Securities Act and with
          the Exchange Act with respect to any such registration.

               10.  Standoff Agreement.  The Holders agree in connection
          with any registration of the Company's securities, upon request
          of the underwriters managing any underwritten offering of the
          Company's securities, not to sell, make any short sale of, loan,
          grant any option for the purchase of, or otherwise dispose of any
          Registrable Shares (other than those included in such
          registration), without the prior written consent of the Company
          or such underwriters, as the case may be, for such period of time
          (not to exceed 120 days) from the effective date of such
          registration as may be requested by the Company or such managing
          underwriters.

               11.  Rule 144 Requirements.  The Company agrees to:

                    (a)  use its best efforts to file with the Commission
          in a timely manner all reports and other documents required of
          the Company under the Securities Act and the Exchange Act; 

                    (b)  furnish to any Holder of Registrable Securities
          upon request (i) a written statement by the Company as to its
          compliance with the requirements of Rule 144(c), and the
          reporting requirements of the Securities Act and the Exchange
          Act, (ii) a copy of the most recent annual or quarterly report of
          the Company, and (iii) such other reports and documents of the
          Company as such Holder may reasonably request to avail itself of
          any similar rule or regulation of the Commission allowing itself
          to sell any such securities without registration; and

                    (c)  cooperate with any Holder in such manner as such
          Holder may reasonably request so as to enable sales made in
          compliance with the requirements of Rule 144 to be made in


                                        - 8 -



          compliance with the requirements of any transfer agent, registrar
          or the broker through whom any sales are to be executed.

               12.  Put Right and Call Offer.

                    (a)  Subject to Section 12(b) below, each Holder shall
          have the right to sell (a "Put Right") during the Put Right
          Exercise Period (as defined below), and upon exercise of that
          right the Company shall purchase, all the Shares then owned by
          such Holder at a purchase price per Share equal to 100% of the
          Specified Price (as defined below) during the Put Right Exercise
          Period.  If the Put Right is not duly exercised during the Put
          Right Exercise Period, it shall expire at the end of the Put
          Right Exercise Period.  A Put Right may be exercised only once by
          each Holder.

                    (b)  The Company may offer to purchase from each Holder
          or from all of the Holders (a "Call Offer") during the Call Offer
          Period (as defined below) all or any portion of the Shares then
          owned by such Holders at a purchase price equal to 110% of the
          Specified Price (as defined below).  The Holders may, at their
          option, accept such Call Offer upon written notice delivered to
          the Company within twenty business days after notice of the Call
          Offer is given to the Holders.  If any Holder does not duly
          accept the Call Offer in accordance with the terms of the Call
          Offer and this Agreement, or if any such Holder accepts the Call
          Offer but subsequently does not sell to the Company the Shares
          agreed to be sold by such Holder to the Company within the period
          provided for in this Section 12, then both the Call Offer and all
          rights of the Holders under Section 12(a) with respect to the
          Shares subject to such Call Offer shall then immediately expire
          and be of no further force and effect.

                    (c)  The "Specified Price" for each Share subject to a
          Put Right or a Call Offer shall be $31.875, which is equal to the
          closing price of the common stock of the Company as reported by
          the New York Stock Exchange on the fifth to the last trading day
          preceding the date of this Agreement.  The "Put Right Exercise
          Period" and the "Call Offer Period" shall each be the 10-day
          period commencing on the 60th day after the date of this
          Agreement.  A Put Right may be exercised and a Call Offer may be
          made only by written notice to the Company or the Holders, as the
          case may be, and such notice shall contain the number of Shares
          to be purchased and the identity of the Holder selling such
          Shares.  The purchase price payable upon purchase and sale of the
          Shares subject to a Put Right or Call Offer hereunder shall be
          paid in cash on the Closing Date (as defined below).

                    (d)  In the event of an exercise of a Put Right or the
          making of a Call Offer, the parties to such transaction shall
          mutually determine a closing date (a "Closing Date") which shall
          not be more than 10 days, subject to any applicable regulatory

                                        - 9 -



          waiting periods, after the date the Put Right is exercised or
          Call Offer is made and accepted by one or more Holders, as the
          case may be, or if any such day is not a business day, then the
          first business day thereafter; provided, however, that in no
          event shall such Closing Date be later than December 30, 1996. 
          Such closing ("Closing") shall be held at 11:00 a.m., local time,
          or at such other time and at such place as the parties may agree. 
          On the Closing Date of a purchase of Shares pursuant to this
          Section, the Holders shall deliver to the Company certificates,
          with stock powers duly endorsed in blank, representing the Shares
          to be purchased.  In the event any such Shares are then held in
          escrow under the Escrow Agreement, such Shares will be delivered
          by the Escrow Agent and the cash proceeds with respect thereto
          will be delivered to the Escrow Agent.  In addition, if the
          person selling the Shares is the personal representative of a
          deceased Holder, the personal representative shall also deliver
          to the Company (i) copies of letters testamentary or letters of
          administration evidencing his appointment and qualification,
          (ii) a certificate issued by the Internal Revenue Service
          pursuant to Section 6325 of the United States Internal Revenue
          Code of 1986, as amended (the "Code"), discharging the Shares
          being sold from liens imposed by the Code (or, if it is not
          possible to obtain such certificate by the Closing Date, the sale
          of such Shares may be consummated and the proceeds placed in
          escrow pending receipt thereof), and (iii) an estate tax waiver
          issued by the state of the decedent's domicile.

               13.  Amendment.  Any provision of this Agreement may be
          amended and the observance thereof may be waived (either
          generally or in a particular instance and either retroactively or
          prospectively), only by the written consent of the Company and
          the Holders.  Any amendment or waiver effected in accordance with
          this Section 16 shall be binding upon each Holder of any
          Registrable Shares then outstanding, each future holder of any
          Shares who is a party to this Agreement, and the Company.

               14.  Notices, etc.  All notices, requests, demands and other
          communications hereunder shall be in writing and shall be deemed
          to have been duly given if delivered by hand, courier service,

          are severable, and in the event that any one or more provisions
          are deemed illegal or unenforceable, the remaining provisions
          shall remain in full force and effect.

               16.  Governing Law.  This Agreement shall be governed by and
          construed in accordance with the laws (other than those with

               17.  Counterparts.  This Agreement may be executed
          simultaneously in any number of counterparts, each of which shall
          be deemed an original, but all of which together shall constitute
          one and the same instrument.
