                          -----------

ranges, heaters, plumbing, gas and electric fixtures, screens, mantels, shades,
screen doors, storm doors and windows, oil burners, gas or electric

or supplies intended to enter into the construction, repair or remodeling of the
buildings on the premises, now in said buildings or on the premises, or placed

to the Mortgagee a security interest in the Property (as hereinafter defined)
and covenants and agrees that, as of the execution hereof and upon the
subsequent acquisition of such furnishings, fixtures, supplies, materials, and
any other improvements and items of personal property the Mortgagor shall have,
and used in connection with the described real estate or purchase from the
proceeds of the loan contemplated hereunder, and for replacement items:

     a)   provide the Mortgagee with the above personal property a precise
          inventory, save for all new and used vehicles and any parts inventory,
          of the same, as and when acquired;

     b)   execute and deliver to the Mortgagee, in form appropriate for
          recording and filing, financing statements on all such articles,
          fixtures, equipment and materials;

 
                                      -2-

     c)   provide to the Mortgagee such other assurances as may be required by
          the holder to establish the holder's first and prior security interest
          in such fixtures, supplies, materials, and any other improvements; and

     d)   execute, deliver and cause to be recorded and filed from time to time,
          without notice or demand, and at the mortgagor's sole cost and
          expense, continuance and such priority of security in such articles,
          fixtures, equipment and materials.

     The above-described furnishings, fixtures, supplies, materials, and realty,
together with any and all improvements now thereon, or from time to time
thereon, and any additions thereto or replacements thereof, are herein
collectively referred to as the "Property". It is understood and agreed that the
security interest in the property delivered to the Mortgagee hereunder shall not
cover property owned by lessees and tenants in possession.

     The Mortgagor covenants:

     1)   to perform all of the covenants and agreements contained in said note;

     2)   to pay before the same become delinquent and a lien against the
          property (and to provide by such time evidence of such payment,
          satisfactory to the holder hereof) all taxes, charges, sewer use fees,
          water rates and assessments of every name and nature, whether or not
          assessed against the Mortgagor, if applicable or related to the
          property, or any interest therein, or the debt, obligation or any
          agreement secured hereby, or the disbursements or the application of
          the proceeds thereof; but the obligations of the Mortgagor under this
          Section 2 contained shall not extend to any income tax or corporation
          excise tax of the holder;

     3)   that if at any time any law or court decree prohibits the performance
          of any material obligation undertaken herein by the Mortgagor, or
          provides that any amount to be paid hereunder by the Mortgagor,
          exclusive of principal and interest payments, must be credited against
          the Mortgagor's obligations under the Note, the holder shall have the
          right, on 30 days' prior written notice to the Mortgagor, to require
          payment in full of the entire indebtedness secured hereby;

     4)   to assure the payment of all taxes, charges, sewer use fees, water
          rates, assessments of every name and nature, or any other obligation
          which may have or acquire priority over this Mortgage, and which are
          assessed or payable with reference to the property, at the election of
          the holder, if and only to the extent the loan to value ratio is more
          than 80%, the Mortgagor shall deposit with the holder, on each day
          when any payment under the Note is required to be made, a sum
          determined by the holder to be sufficient to provide, in the
          aggregate, a fund adequate to pay any such amounts 1 day at least
          before the same become delinquent; and whenever the holder determines
          sums accumulated under the provisions of this Section 4 to be
          insufficient to meet the obligation for which such deposits were made,
          the Mortgagor shall pay within 10 days of demand of 

 
                                      -3-

          the holder, any amount required to cover the deficiency therein; every
          deposit may, at the option of the holder, be applied directly against
          the obligation with reference to which it was made, or, to the fullest
          extent permissible according to law, any other obligation of the
          Mortgagor secured hereby; such deposits may be commingled with other
          assets of the holder and, in the discretion of the holder, invested by
          the holder for its own account, without any obligation to pay income
          from such investment, or interest on such deposits, to Mortgagor, or
          to account to Mortgagor for such income in any manner;

     5)   not to suffer any act in its nature capable of materially harming the
          value of the mortgaged premises, irrespective of whether or not such
          act may constitute waste; not to suffer to be made any material
          alteration or change in the use, occupancy, or structural condition of
          the mortgaged premises unless the written consent of the Mortgagee be
          first obtained in each particular case; to keep all and singular the
          said premises in such repair, order and condition as the same are now
          in or may be in while the Mortgage is outstanding, reasonable wear and
          tear only excepted; not to permit or suffer any violation of any law,
          ordinance or regulation affecting the mortgaged premises or the use
          thereof, except to the extent Mortgagor may in good faith contest the
          validity or effect thereof by duly instituting proceedings as long as
          the action underlying the same is stayed; that the Mortgagee may, in
          its discretion upon reasonable notice and reasonable times, enter upon
          and make repairs as in its judgment may be necessary to keep said
          premises in good condition and repair, and that all money so expended
          shall be secured by this Mortgage, shall draw interest at the rate
          provided in the note from the date of the advance of such payment and
          shall be payable by the Mortgagor to the Mortgagee at such time and in
          such amounts as the Mortgagee may determine;

     6)   to carry with respect to the property and its use physical hazard
          insurance on an "all risks" basis covering the perils of fire,
          extended coverage and special extended coverage (including earthquake,
          boiler explosion, collapse, costs of demolition and contingent
          liability from the operation of any building laws as they may pertain
          to nonconforming property) in an amount not less than 100% of the full
          replacement cost of all building improvements and interests thereof
          and Mortgagor's contents therein, and during the construction of any
          improvements which become a part of the property, to carry insurance
          in "Builder's Risk completed value (non-reporting)" form, including
          all risk type coverage and to carry such liability insurance coverage
          as the holder shall from time to time reasonably require; initial
          minimum limits of $1,000,000.00 which limits may be reviewed annually
          by Mortgagee; all insurance (with evidence of payment of premiums
          thereon satisfactory to the holder) so required to be maintained,
          together with any other insurance with respect to the property
          maintained by the Mortgagor, shall be deposited with, and, except for
          public liability coverage and except to the extent of the first
          $50,000.00 in aggregate of losses payable in any calendar year, and
          any other coverage the holder may determine shall not by payable to it
          in case of loss, shall be first payable in case of loss to the holder;
          all 

 
                                      -4-

          renewals or replacements of such insurance from time to time in
          force together with evidence of payment of premiums thereon
          satisfactory to the holder shall be delivered to the holder 1 day at
          least before the expiration date of then current insurance; all
          insurance required as aforesaid to be maintained with respect to the
          property shall be written by such companies, on such terms, in such
          form and for such periods and amounts as the holder shall from time to
          time approve and shall not be cancelable or amendable without at least
          15 day's prior written notice to the holder; and no settlement on
          account of any loss covered by such insurance, exceeding $50, 000.00
          in the aggregate in any calendar year, shall be effected without the
          consent of the holder;

     7)   except as provided in Paragraph 6, the proceeds of any hazard
          insurance shall, at the option of the holder (i) be applied to or
          toward the indebtedness secured hereby in such order as the holder may
          determine (in which event the Mortgagor shall be relieved of the
          obligation in Section 5 of this Mortgage to the extent of the repair
          of that part of the property damaged by the hazard with respect to
          which insurance is paid); or (ii) if the holder shall require repair
          of that part of the property so damaged by the insured hazard, the
          holder shall release to the Mortgagor insurance proceeds paid to it
          upon such reasonable conditions as the holder may prescribe and upon
          completion of such repair shall, at the holder's option, apply any
          excess insurance proceeds to or toward the indebtedness secured hereby
          in such order as the holder may determine or release the same to the
          Mortgagor; notwithstanding any thing in this Section 7 to the
          contrary, however, if the insurer denies liability to the Mortgagor,
          except where such denial is based on the negligence of the Mortgagee,
          the Mortgagor shall not be relieved of any obligation under Section 5
          of this Mortgage, whether or not the proceeds of insurance are applied
          to or toward the indebtedness secured hereby;

     8)   the awards of damages on account of any condemnation for public use of
          or injury to the property shall be paid to the holder; such awards
          shall, at the option of the holder (i) be applied to or toward the
          indebtedness secured hereby in such order as the holder may determine,
          in which event the Mortgagor shall be relieved of the obligation of
          Section 5 of this Mortgage to the extent of the repair of that part of
          the property which remains and which has been damaged or injured by
          such public action; or (ii) if the holder shall require restoration of
          that part of the property which remains, the holder shall release to
          the Mortgagor such awards paid to it upon such conditions as the
          holder may reasonably prescribe, but not more than such portion of
          such awards as may be required to repair such damage or injury; and
          any balance remaining shall be applied by the holder to or toward the
          indebtedness secured hereby in such order as the holder may determine;

     9)   to use its best efforts continuously to use and occupy the property or
          cause the property to be used or occupied;

 
                                      -5-

     10)  except in the ordinary course of business in each instance, not to
          lease the property or any substantial part thereof, without the prior
          written consent of the holder; faithfully to keep, observe and satisfy
          all the obligations on the part of the lessor to be kept, performed
          and satisfied under every lease from time to time in force with
          reference to the property, except upon default of the tenant, and not
          to alter or terminate any such lease or accept rentals for more than
          one month's rental in advance; and, at any time on notice from the
          holder, to submit to the holder for examination all such leases and on
          the demand of the holder, to assign and deliver to the holder any or
          all such leases, or and upon and after an Event of Default the rents
          and profits thereof, such assignments to be in form satisfactory to
          the holder, but in all events to provide that the Mortgagor shall
          retain the rents and profits thereof until an Event of Default occurs
          in any covenant or condition in this Mortgage; and the holder shall
          have the right, by the execution of suitable written instruments from
          time to time, to subordinate this Mortgage, and the rights of the
          holder hereunder, to any lease or leases from time to time, in force
          with reference to the property, and, on the execution of any such
          instrument, this Mortgage shall to the extent permitted by law be
          subordinate to the lease for which such subordination is applicable
          with the same force and effect as if such lease had been executed and
          delivered, and a notice thereof recorded to the extent required to
          give notice to third persons, prior to the execution, delivery and
          recording of this Mortgage;

     11)  "Deleted in its Entirety"

     12)  that, at the option of the holder, upon the occurrence of any Event of
          Default under the Note, the rate of interest stated on the face hereof
          shall be increased by an additional three percent (3%) per annum above
          the Rate until such amount shall be paid in full (whether before or
          after judgment), said increased rate of interest shall remain in
          effect for such time as the event of default continues;

     13)  that, from time to time, on the written request of the holder, the
          Mortgagor shall furnish within 10 days of said request a written
          statement, signed and, if requested, acknowledged, setting forth the
          amount of the indebtedness which the Mortgagor acknowledges to be due
          on the Note and under this Mortgage, specifying any claims of offset
          or defense which the Mortgagor asserts against the indebtedness
          secured hereby or any obligations to be paid or performed hereunder,
          and the then state of facts relative to the condition of the property;

     14)  whether or not for additional interest or other consideration paid or
          payable to the holder, no forbearance on the part of the holder or
          extension of the time for the payment of the whole or any part of the
          obligations secured hereby, whether oral or in writing, or any other
          indulgence given by the holder to the Mortgagor or to any other party
          claiming any interest in or to the property, shall operate to release
          or in any manner affect the original liability of the Mortgagor, or
          the priority of this Mortgage or to limit, prejudice or impair any
          right of the holder, including, 

 
                                      -6-

          without limitation, the right to realize upon the security, or any
          part thereof, for the obligations secured hereby or any of them,
          notice of any such extension, forbearance or indulgence being hereby
          waived by the Mortgagor and all those claiming by, through or under
          the Mortgagor; and no consent or waiver, express or implied, by the
          holder to or of any default by the Mortgagor shall be construed as a
          consent or waiver to, or of any further default in the same or any
          other term, condition, covenant or provision of this Mortgage or of
          the obligations secured hereby; in case redemption is had by the
          Mortgagor after foreclosure proceedings have begun, the holder shall
          be entitled to collect all costs, charges and expenses incurred up to
          the time of redemption; in case of foreclosure sale, the holder shall
          be entitled to the costs, charges and expenses allowed under the
          Statutory Power of Sale; and in case any one or more of the provisions
          of this Mortgage may be found to be invalid, or unenforceable for any
          reason or in any respect, such invalidity or unenforceability shall
          not limit or impair enforcement of any other provision hereof;

     15)  that wherever notice, demand or a request may properly be given to the
          Mortgagor under this Mortgage, the same shall always be sufficient to
          serve as a notice, demand or request hereunder if in writing and sent
          by registered or certified mail, postage prepaid, return receipt
          requested, so-called express mail, private express carrier or hand
          delivery, addressed to the Mortgagor at the address given in this
          Mortgage as the Mortgagor's address and to the Mortgagor at 41 Meeting
          House Lane, P.O. Box 327, Sagamore Beach, Massachusetts 02562; and any
          such notice, demand or request shall be treated as having been given
          upon receipt or tender for delivery at the notice address; and a
          notice so addressed shall always be sufficient notice, notwithstanding
          a change in the ownership of the equity of redemption of the property,
          whether or not consented to by the holder; and where more than one
          person constitutes the Mortgagor, one notice sent to the address given
          in this Mortgage as the Mortgagor' s address or the last known
          business address of any one of them shall constitute sufficient notice
          to all;

     16)  the undertakings of the Mortgagor contained in Section 2 of this
          Mortgage with respect to items other than the payment of real estate
          taxes, sewer use fees, water rates, and assessments, shall survive the
          payment of all obligations secured hereby; however, after an
          acknowledgment of the satisfaction of the obligations secured hereby,
          or a discharge of this Mortgage, this Mortgage shall not be security
          for the performance of such undertakings, notwithstanding the survival
          of the same; but, thereafter, and notwithstanding anything to the
          contrary contained in the Note, this Mortgage or any other document or
          instrument securing the Note, the holder shall look solely to the
          Mortgagor, personally, for the performance of such undertakings;

     17)  that without limiting the scope and effect of other provisions of the
          Mortgage, to the extent that any of the property is of a nature that a
          security interest therein may be perfected under the Uniform
          Commercial Code, as enacted in the 

 
                                      -7-

          Commonwealth of Massachusetts, this instrument shall, as of the date
          of execution hereof, constitute a security agreement granting to the
          holder a security interest in the property. Without limiting the
          generality of the foregoing, the security interest held by the secured
          party shall cover cash and noncash proceeds of that portion of the
          property which is subject to a security interest. Further, with
          respect to that portion of the property which is subject to a security
          interest, the Mortgagor agrees with the holder as follows:

          a)   such portion shall continue to be free from all pledges, liens,
               encumbrances and security interest or other claims in favor of
               others, except in the case of purchase money security interests,
               and that the Mortgagor will warrant and, at the holder's request,
               defend the same from all claims and demands of all persons, and

          b)   such portion is to be located on the real estate which is
               included as part of the property and will not be removed
               therefrom without the prior written consent of the holder unless,
               upon such removal, similar items of equal value are substituted
               or replaced.

     18)  that annually, within one hundred fifty (150) days after the 
          expiration of each calendar year, or fiscal year, if applicable, and
          at no expense to the holder, the Mortgagor shall deliver to the holder
          audited financial statements for the Mortgagor, showing a true and
          complete treatment of the annual operating expenses and income of the
          property, and financial statements and tax returns of the Mortgagor
          and any guarantors or endorsers, such statements to be in form
          reasonably satisfactory to the holder;

     19)  that the Mortgagor will, from time to time at the holder's request,
          make, execute, deliver, file and record all such instruments,
          conveyances, notices, financing statements and other documents, and
          take all such further action as the holder may determine to be
          reasonably necessary or advisable for the better assuring and
          confirming to the holder of its security interests in the property or
          any part thereof, and will so execute, deliver, file and record such
          instrument or instruments as the holder may request;

     20)  that in addition to other payments herein required, the Mortgagor
          shall, at the Mortgagee's option, exercisable at any time or from time
          to time, if and only to the extent the loan to value ratio exceeds
          80%, now or in the future, pay to the Mortgagee monthly on the 21st
          day of each month, or such other day of the month as may be designated
          by the mortgagee during the term hereof, and for so long as the
          Liabilities secured by this Agreement shall remain unpaid, an amount
          equal to one-twelfth (1/12th) of the municipal taxes and assessments
          which the Mortgagee estimates will become due and payable on account
          of the Mortgaged Premises for the year next succeeding any period for
          which such taxes and assessments have been paid or escrowed hereunder
          sufficient, to enable Mortgagee to accumulate at 

 
                                      -8-

          least thirty (30) days prior to the dates upon which such municipal
          taxes and assessments are payable the amounts then due and payable.
          Further, the Mortgagor shall pay to the Mortgagee on demand the amount
          of any deficiency of the funds so collected when the actual amount of
          such taxes and assessments becomes known. The Mortgagee shall maintain
          such funds in an interest bearing account which may be co-mingled with
          other funds of the Mortgagee. The Mortgagee shall apply said funds to
          the payment of municipal taxes and assessments, as applicable, to the
          extent such amounts are determined by he Mortgagee to be due and
          payable. In the event the Mortgagee collects such tax payments
          hereunder, the Mortgagor shall deliver to the Mortgagee the bills
          representing any such amounts within ten (10) days of the receipt
          thereof by the Mortgagor. Notwithstanding the provisions of this
          section, upon an occurrence of an event which is, or, solely with the
          passage of time, would be, an Event of Default hereunder, the
          Mortgagee shall not be required to apply such funds as provided above,
          and may set off such funds against the Liabilities and apply any such
          funds towards the Liabilities in accordance with the terms herein.

     21)  that the following are conditions of this Mortgage:

          a)   the covenants and agreements herein contained shall not be
               breached;

          b)   except for real estate taxes and assessments until 1 day before
               any delinquency therein (delinquency, with reference to such
               taxes and assessments being hereby defined, for the purposes of
               this Mortgage, as meaning the time when, on the non-payment
               thereof, interest or penalties commence to accrue), not to create
               any encumbrance on the property even if such encumbrance is
               inferior to this Mortgage;

          c)   the Mortgagor shall not permit any encumbrance to exist against
               the property, even if such encumbrance is inferior to this
               Mortgage; without limitation, the filing of a notice of Federal
               or State tax lien with the holder or at the office at which, by
               law, such notice is to be filed to be effective against the
               property, whether or not such lien applies, in terms, to the
               property, shall be a breach of this condition; and any period of
               grace in this Mortgage provided to the Mortgagor for a default in
               this Mortgage shall not be applicable to the filing of such a
               notice of governmental lien or to any encumbrance created by the
               Mortgagor;

          d)   the Mortgagor shall not make or permit any transfer, sale, or
               other disposition of any part or all of its interest in the
               Property other than in the ordinary course of business or of any
               ownership interest in the Mortgagor without the prior written
               approval of the holder hereof, which said approval shall not be
               unreasonably withheld. No such transfer, sale or other
               disposition and no forbearance on the part of the holder or
               extension of the time for the payment of the debt secured hereby
               or any other


 
                                      -9-

               indulgence given by the holder shall operate to release,
               discharge, modify, change or affect the original liability of the
               Mortgagor, nor the priority of this Mortgage either in whole or
               in part, notice of such forbearance, extension or other
               indulgence being herein expressly waived;

          e)   no ownership interest of the Mortgagor in the limited partnership
               shall be transferred, without the prior written consent of the
               holder, to any person other than the stockholders of the
               Mortgagor in existence on the date of this Mortgage, or members
               of their immediate families;

          f)   the Mortgagor shall not file a petition or any application for
               relief, extension, moratorium or reorganization under any
               bankruptcy, insolvency or debtor's relief law, or make an
               assignment for the benefit of creditors or enter into any trust
               mortgage arrangement, so-called, or consent to the appointment of
               a receiver or any of the property of the Mortgagor; and

          g)   the Mortgagor shall not permit any petition under any bankruptcy,
               insolvency or debtor's relief law filed against it, to remain
               undischarged for a period of more than 45 days after the filing
               thereof, nor shall the Mortgagor permit the continuation of any
               receivership proceedings instituted against it for more than a
               period of 45 days after the commencement thereof;

          h)   the Mortgagor shall not breach any provisions of any lease
               relative to the property which would allow the lessee under said
               lease to terminate the same, affecting more than 10% of the
               warehouse square footage at the property in any one year;

          i)   the Mortgagor shall not breach any covenant contained in any loan
               documents executed herewith regarding the loan described herein,
               which breach has continued beyond any applicable cure or grace
               period;

     22)  that the following are Events of Default:

          a)   if any payment required under the Note or this Mortgage shall not
               be made when due;

          b)   if there shall be any breach of the conditions of Sections 21 b),
               21 d), 21 e), 21 f), 21 g) and h) of this Mortgage or the
               covenant in Section 4 of this Mortgage; or

          c)   if there shall be any breach of the condition of Section 21 c) of
               this Mortgage in any respect other than the filing of a
               governmental lien continuing for more than 30 days; or

 
                                     -10-

          d)   if there shall be any breach of the other conditions or covenants
               of this Mortgage which shall exist for more than 30 days after
               notice thereof from the holder (except where a period of grace is
               specifically otherwise provided or negated, in which case, such
               specific periods of time or negotiation shall govern);

          (e)  if the note secured by this Mortgage and any other obligations of
               the Mortgagor or any Co-maker, Guarantor or Endorser to the
               Mortgagee hereof, or assigned to or held by the Mortgagee, is
               further secured by additional security, any breach in the
               performance of any of the conditions contained in any of said
               other security shall also constitute a breach of the conditions
               of this Mortgage. Similarly, the breach of the conditions of this
               Mortgage shall likewise constitute a breach of all of the said
               additional security; and in the event of a foreclosure hereunder
               or under said additional security, the Mortgagee shall have the
               right to foreclose either this Mortgage or any of said additional
               security, jointly or severally, and in such order as in the sole
               opinion of the Mortgagee will be deemed best to protect the
               interest of the Mortgagee in both or either of this mortgage and
               said additional security; that the Mortgagee, in the event of a
               foreclosure of this mortgage or of the additional security shall
               have the right to offer the real estate and said additional
               security for sale as a unit or separately, and, if as a unit, may
               allocate any price received therefor between said real estate and
               said additional security.

     Upon an Event of Default, and without derogating from the rights of the
     holder to demand payment of the Note in accordance with the terms of the
     Note, the holder shall have the right to declare the entire indebtedness of
     the Mortgagor under the Note forthwith due and payable.

     For the purposes of this Mortgage, the term "default", as used in the
     STATUTORY POWER OF SALE, shall mean an Event of Default, as defined herein;

23)  that if there shall be any breach in any condition or covenant of this
     mortgage which constitutes an Event of Default, the holder shall have the
     right, but without any obligation so to do, to cure such default for the
     account of the Mortgagor and, to the fullest extent permissible according
     to law, apply any funds credited by or due from the holder to the Mortgagor
     against the same (without any obligation first to enforce any other rights
     of the holder, including, without limitation, any rights under the Note or
     this Mortgage, or any guarantee thereof, and without prejudice to any such
     rights); without limiting the generality of the foregoing, the Mortgagor
     hereby authorizes the holder to pay all taxes, sewer use fees, water rates
     and assessments, with interest, costs and charges accrued thereon, which
     may at any time be a lien upon the property, or any part thereof; to pay
     the premiums for any insurance required hereunder; to incur and pay
     reasonable 

 
                                     -11-

     expenses in protecting its rights hereunder and the security hereby
     granted; to pay any balance due under any Security Agreement on any
     articles, fixtures, equipment and materials included as a part of the
     property; and the payment of all amounts so incurred, together with
     interest thereon at the annual rate specified in the Note as the interest
     to be paid on the indebtedness evidenced by the Note shall be secured
     hereby as fully and effectually as any other obligation of the Mortgagor
     secured hereby; and, to the fullest extent permissible according to law, to
     apply to any of these purposes or to the repayment of any amounts so paid
     by the holder together with interest thereon any sums paid on the Note or
     this Mortgage by the Mortgagor as interest or otherwise;

24)  that, at any foreclosure sale, any combination, or all, of the property or
     security given to secure the indebtedness secured hereby, may be offered
     for sale for one total price, and the proceeds of such sale accounted for
     in one account without distinction between the items of security or without
     assigning to them any proportion of such proceeds, the Mortgagor hereby
     waiving the application of any doctrine of marshalling; and, in case the
     holder, in the exercise of the power of sale herein given, elects to sell
     in parts or parcels, said sales may be held from time to time, and the
     power shall not be fully executed until all of the property or security not
     previously sold shall have been sold;

25)  that, if the provisions of the Uniform Commercial Code as adopted in
     Massachusetts are applicable to any property or security given to secure
     the indebtedness secured hereby which is sold in combination with or as a
     part of the property, or any part thereof, at one or more foreclosure
     sales, any notice required under such provisions shall be fully satisfied
     by the notice given in execution of the Statutory Power of Sale (referred
     to below) with respect to the property or any part thereof;

26)  that Mortgagor agrees to and hereby does indemnify and hold harmless the
     holder from and against any and all loss, cost or expense including,
     without limitation, any clean-up costs and fines incurred by the holder and
     arising out of or in any way connected with the application of any federal,
     state, County, Regional and local laws pertaining to the use, storage or
     existence of hazardous or toxic materials or environmental hazard on the
     property, including, without limitation, Massachusetts General Laws,
     Chapter 21E and in this connection the Mortgagor covenants that the
     property is not now being used and will not be used for any activities
     involving, directly or indirectly, the use, generation, treatment, storage
     or disposal of any hazardous or toxic chemical, material, substance or
     waste, including without limitation (a) asbestos in any form; (b) urea
     formaldehyde foam insulation; (c) transformers or other equipment which
     contain dielectric fluid containing polychlorinated byphenyls; (d) any
     other hazardous or toxic chemical, material, substance or waste, exposure
     to which is prohibited, limited or regulated by any federal, state, county,
     regional or local authority; in furtherance of the foregoing, Mortgagor
     agrees to take all steps necessary in order to prevent any 

 
                                     -12-

          lien pursuant to said laws from attaching to the property or any part
          thereof; the Mortgagor's liability under this Section shall survive
          transfers of the property by the Mortgagor and foreclosure of this
          Mortgage;

     Notwithstanding any provision herein to the contrary, Mortgagor shall have
no liability hereunder (a) to holder as to any matter for which Mortgagor might
otherwise be liable hereunder which is not caused or contributed to by Mortgagor
and which is caused by or due to the negligence of the holder or (b) to any
successors or assigns of holder for any matter for which Mortgagor might
otherwise be liable hereunder, which is not caused or contributed to by
Mortgagor, and which is caused by or due to the negligence of any such successor
or assign.

     The word "holder", as used herein, shall mean the Mortgagee named at the
beginning of this instrument and any subsequent holder or holders of this
Mortgage.

     The word "Mortgagor", as used herein, shall mean the person named at the
beginning of this instrument as the Mortgagor, and any subsequent owner or
owners of the equity of redemption of the property (but such reference is not
intended as a consent by the holder to any transfer of such equity by the
Mortgagor to which the holder has not provided its prior written consent).

     All the covenants and agreements of the Mortgagor herein contained shall be
binding upon the Mortgagor and the successors and assigns of the Mortgagor.

This MORTGAGE is upon the STATUTORY CONDITION, and upon the further condition
that all covenants and agreements of MORTGAGOR herein or contained in the note
or other collateral documents and all other conditions thereof shall be kept and
fully performed, for any breach of which the Mortgagee shall have the STATUTORY
POWER OF SALE.

     Executed as a sealed instrument this 21st day of April, 1995.

$2,600,000.00                                     HYANNIS, MASSACHUSETTS
                                                  April 21, 1995


     The undersigned (jointly and severally if more than one) for value
received, promise to pay to the order of

                 CAPE COD BANK AND TRUST COMPANY (the "Bank")

at the Head Office of the Bank, at 307 Main Street, Hyannis, MA 02601, TWO
MILLION SIX HUNDRED THOUSAND AND NO/100 ($2,600,000.00) DOLLARS seven (7) years
after the date of this Note and, until this Note is paid in full, interest and
principal shall be payable as follows:

     Interest only shall be payable monthly during the first six months of the
term of this Note at the annual rate of the Prime Rate of Interest as published
in the Wall Street Journal (the "Prime Rate") plus three quarters (.75%) percent
per annum (the "Rate") computed on the unpaid principal balance with the first
payment due May 21, 1995, changes in the Rate to take effect on the date changes
in the Prime Rate are published in the Wall Street Journal; and

     Thereafter (the "Amortization Period") monthly payments of TWENTY-EIGHT
THOUSAND AND NO/100 ($28,000.00) DOLLARS ("Amortization Payments") shall be
payable with the first payment due on November 21, 1995 with Amortization
Payments being first applied to interest then due and the balance, if any, to
principal.

     At each anniversary date the Bank reserves the right:

     1.   To call for an additional payment of principal equal to the amount of
the principal which would have been paid had the amortization payments been
adjusted to reflect changes in the interest note in order to maintain a fifteen
year amortization schedule; and

     2.   To recalculate the amortization payments in order to maintain a
fifteen year amortization schedule calculated from the date of the note.

     In the event that any monthly payment due hereunder is not paid within Ten
(10) days of the due date, there shall become due hereunder, at the option of
the Bank hereof, a late charge of three and 00/100 (3.00%) percent of the amount
overdue.

     The undersigned has granted to the Bank a mortgage on the following
described property to secure the payment and performance of all obligations:

 
     Land, together with the buildings thereon, situated at 60, 70 and 80
     Perseverance Way, Hyannis, Massachusetts, together with certain personal
     property of the undersigned.

     In addition to the above property, all other property belonging to,
standing in the name of or pledged on behalf of the undersigned which is now or
may hereafter be in the possession of the Bank for any purpose, and also any
other property described in one or more agreements or mortgages which have been
or shall be delivered or caused to be delivered, to the Bank by the undersigned,
together with all additions or accessions thereto (all of the foregoing being
hereinafter called "Collateral") , shall constitute continuing security for any
and all obligations.

     In the event the undersigned is in default under the terms and provisions
of the loan, or the unpaid principal and interest and other charges due the Bank
are not paid when due, including acceleration after default, then the default
rate of interest on the unpaid principal and interest then due shall be equal to
the aggregate of the Rate of interest recited herein from time to time plus
three (3.00%) percent per annum until such amount shall be paid in full (whether
before or after judgment).

     In the event the Borrower pays the Note in full in or within three (3)
years from the date hereof, the Borrower shall pay the Bank an exit fee in the
amount of one-half (.50%) percent of the then outstanding principal balance.

     The entries on the records of the Bank (including any appearing on this
Note) shall be prima facie evidence of the aggregate principal amount
outstanding under this note and interest accrued thereon.

     The Borrower agrees that it will not permit the outstanding balance of the
Loan to exceed 80% of the Bank's then current appraised value of the portion of
the Collateral known as 60, 70 and 80 Perseverance Way, Hyannis, Massachusetts
02601.  Any appraisal required by the Bank shall be performed by an appraiser of
the Banks choice and shall be at the cost of the Borrower.  Notwithstanding any
provision to the contrary, in the event of a default hereunder, the Bank shall
notify the Borrower in writing and Borrower shall have 30 days to cure by
furnishing additional collateral satisfactory to the Bank.

     The undersigned represents and warrants that (a) all Collateral is owned by
the undersigned or by the person(s) delivering all or any part of the property
to the Bank to be held as Collateral and is not subject to any liens, security
interests or rights of others, except those approved by the Bank in writing, and
its delivery to the Bank has been duly authorized by all necessary action, and
that (b) the Collateral is genuine and is what it purports to be.

     The Bank may at its option, whether or not this note is due, demand, sue
for, collect, or make any compromise or settlement it deems desirable with
reference to any Collateral.  Right is expressly granted to the Bank at its
option to transfer at any time to itself or to its nominee any securities,
documents or other property pledged hereunder and to receive the income thereon
and hold the same as security therefor, or apply it on the principal or interest
due hereon or due on 

 
any liability secured hereby. The Bank shall have no duty as to the protection
or collection of any Collateral or any income thereon, and shall be bound to
take any steps necessary to preserve any rights in any Collateral against prior
parties. The Bank shall not exercise its right to vote any voting securities
comprising Collateral unless an event of default under this note has occurred
and the Bank had notified the undersigned or successors and assigns thereof, in
writing of its intention to vote such securities.

     The undersigned shall furnish the Bank from time to time, and at least
annually within one hundred fifty (150) days after the end of the Borrower's
fiscal year-end, with such financial statements as the Bank may require in form
satisfactory to the Bank.  Financial information furnished to the Bank shall be
true and correct and fairly represent the financial condition of the undersigned
as of the date(s) furnished and the operating results of the undersigned for the
periods for which the same are furnished.  The undersigned shall permit the
representatives of the Bank to inspect its properties and its books and records,
and to make copies or abstracts thereof.

     If the undersigned, as registered Bank of securities comprising Collateral,
received (a) any dividend or other distribution in cash or other property in
connection with the liquidation or dissolution of the issuer of such securities
or (b) any stock certificate, option or right, whether as an addition to, in
substitution of, or in exchange for, such securities, or otherwise, the
undersigned agrees to accept same in trust for the Bank, and to forthwith
deliver same to the Bank in the exact form received, with the undersigned's
endorsement and/or assignment when necessary, to be held by the Bank as
collateral.

     Upon the occurrence of any of the following events of default: (a) default
in the payment or performance of any of the Obligations (including any failure
to pay any installment of principal or interest hereunder when due) or of any
obligations of any Obligor to others for borrowed money or in respect of any
extension of credit or accommodation; (b) failure of any representation and
warranty hereunder or of any representation or warranty, statement or
information in any documents or financial statements delivered to the Bank for
the purpose of inducing it to make or maintain the loan under this note to be
true and correct; (c) failure of the undersigned to file any tax return, or to
pay or remit any tax, when due; (d) failure to furnish the Bank promptly on
request with financial information about, or to permit inspection by the Bank of
books, records and properties of, any Obligor; (e) any financial information
furnished to the Bank reflecting operating loss and/or total liabilities in
excess of total assets, as determined by generally accepted accounting
principles; (f) loss, theft, substantial damage, sale or encumbrance to or of
any property constituting collateral or the making of any levy, seizure or
attachment thereof or thereon or the failure to pay when due any tax thereon or,
with respect to any insurance policy, any premium therefor; (g) default under
any instrument constituting, or under any agreement relating, to Collateral; (h)
any Obligor generally not paying its debts as they become due; (i) death,
dissolution, termination of existence, business failure, appointment of a
receiver or other custodian of any part of the property of, assignment for the
benefit of creditors by, or the commencement of any proceedings under any
bankruptcy or insolvency laws by or against, any Obligor; (j) change in the
condition or affairs (financial or otherwise) of any Obligor which in the
opinion of the Bank will impair its security or increase its risk (thereupon or
at any time thereafter such default not having been previously cured), at the
option of the Bank, all 

 
Obligations of the undersigned shall become immediately due and payable without
notice or demand and the Bank shall then have in any jurisdiction where
enforcement hereof is sought, in addition to all other rights and remedies, the
rights and remedies of a secured party under the Uniform Commercial Code of
Massachusetts.

     Without limiting the foregoing and in addition thereto, a failure to pay
when due two or more installments of principal or payments of interest (whether
consecutive or not) under this note shall be a default which shall not be deemed
waived by the Bank by its acceptance of such payments.

     Any sums from time to time credited by or due from the Bank to any Obligor
and any property of any Obligor in which the Bank has from time to time any
security interest or which from time to time may be in the possession of the
Bank for any purpose shall also constitute collateral for the payment or
performance of the obligations of such Obligor, and the undersigned hereby
grants the Bank a continuing security interest in such sums and property.
Regardless of the adequacy of Collateral the Bank may apply such sums or
