          claimed to have been performed at the direction of the Lessee and
          shall cause any such lien to be released of record forthwith
          without cost to the Lessor.  Any alterations or improvements made
          by the Lessee shall become the property of the Lessor at the
          termination of the occupancy as provided therein, except for
          ordinary removable trade fixtures.  At the conclusion of the
          lease term, the Lessor reserves the right to require the Lessee
          to remove any alterations that it made during the lease term.

               20.  LESSEE'S LIABILITY INSURANCE.  The Lessee shall
          maintain with respect to the leased premises and the property of
          which the leased premises are a part comprehensive public
          liability insurance in the amount of $1,000,000 with property
          damage insurance in limits of $500,000 in responsible companies
          qualified to do business in New Hampshire and in good standing
          therein, insuring the Lessor as well as Lessee against injury to
          persons or damage to property as provided.  The Lessee shall
          deposit with the Lessor certificates for such insurance at or
          prior to the commencement of the term, and thereafter within
          thirty (30) days prior to the expiration of any such policies. 
          All such insurance certificates shall provide that such policies
          shall not be canceled without at least ten (10) days prior
          written notice to each insured named therein.

               21.  DESTRUCTION BY FIRE.

               21.01      DUTY TO REPAIR.  If the Premises should be
          damaged during the Term by fire or other casualty covered by the
          usual extended coverage carried by Lessor, Lessor shall (except
          as hereinafter provided) repair the Premises.

               21.02      RIGHT TO TERMINATE.  If, however, the Premises or
          the Building of which the Premises are a part should be damaged
          or destroyed:

               (a)  by fire or other casualty covered by the usual extended
          coverage carried by Lessor (i) to the extent of thirty (30%)
          percent or more of the cost of replacement of either the Premises
          or the Building, or (ii) so that thirty percent (30%) or more of
          the Gross Leasable Area contained in either thereof shall be
          rendered untenantable; or

               (b)  by any casualty other than those covered by standard
          fire and extended coverage insurance policies; or

               (c)  the Premises shall be damaged in whole or in part
          during the last year of the term; or

               (d)  if Lessor s insurer shall refuse, for any reason, to
          settle a covered claim; or

               (e)  if any Mortgagee shall require that the insurance
          recovery arising from the damage or destruction be applied
          against the principal balance due on such Mortgage; then, in any
          such event, Lessor may, at its option, either terminate this
          lease or elect to repair the Premises.  Lessor shall notify
          Lessee as to its election within ninety (90) days after the
          occurrence of the damage in the event of an uninsured casualty. 
          If Lessor elects to terminate this Lease, the term hereof shall
          end at the end of the calendar month in which such election is
          made.  If Lessor does not elect to terminate this Lease, then
          Lessor shall perform such repairs and rebuilding as is necessary
          to provide Lessee with the same or nearly the same demised
          premises as was delivered at the commencement of the Lease (or as
          altered during the term by mutual consent); and the term shall
          continue without interruption and this Lease shall remain in full
          force and effect.  If the Premises are not repaired within one
          hundred eighty days after casualty, Lessee will have the option
          to terminate this lease.

               21.03  RENT ABATEMENT.  If this Lease is not terminated as
          above provided, then from and after such damage and until the
          Premises are restored as above provided, the rent reserved herein
          shall abate, either wholly or proportionately, according to the
          extent that the Premises have been rendered untenantable by such
          damage or destruction.

               22.  INDEMNIFICATION AND LIABILITY.  Lessee shall save
          harmless and indemnify Lessor from any liability for injury,
          loss, accident, or damage to any person or property, and from any
          claims, actions, proceedings and expenses and costs in connection
          therewith, including without limitation reasonable counsel fees
          (i) arising from the omission, fault, willful act, negligence, or
          other misconduct of Lessee or its employees, servants, agents,
          licensees or invitees or from any use made or occurrence on or
          about the Premises.  Lessee shall also indemnify and hold Lessor
          harmless from and against any losses, costs, damages or claims of
          whatever nature, arising out of or in connection with the
          compliance requirements set forth in the Americans with
          Disabilities Act of 1990, Title III, relating to Lessee's design,
          renovations, alteration and/or construction of the Premises.

               23.  LESSOR'S ACCESS.  The Lessor or agents of the Lessor
          may, at reasonable times, enter to view the Premises and may
          remove placards and signs not approved and affixed as herein
          provided, and make repairs and alterations as Lessor should elect
          to do subject to paragraph 14 excepting those repairs necessary
          to protect the building or people from damage and may show the
          Premises to others at any time within one hundred twenty (120)
          days before the expiration of the term.

               24.  SUBORDINATION.  This Lease shall be subject and
          subordinate to any and all mortgages, deeds of trust and other
          instruments in the nature of a mortgage, now or at any time
          hereafter, a lien or liens on the property of which the Premises
          are a part.  Lessee shall upon request promptly execute and
          deliver such written instruments as shall be necessary to show
          the subordination of this Lease to said mortgages, deeds of trust
          or other such instruments in the nature of a mortgage, provided
          that in the instruments of subordination, the mortgagee or
          trustee or assignee shall agree that so long as the Lessee shall
          not be in default of the Lease, the Lessee shall not be disturbed
          in the quiet enjoyment of the Premises.

               25.  DEFAULT AND BANKRUPTCY.  In the event that:

               (a)  the Lessee shall default in the payment of any
          installment of rent or other sum herein specified and such
          default shall continue for five (5) days after written notice
          thereof; or

               (b)  the Lessee shall default in the observance or
          performance of any other of the Lessee's covenants, agreements,
          or obligations hereunder and such default shall not be corrected
          within twenty (20) days after written notice theretofor.

               (c)  the Lessee shall be declared bankrupt or insolvent
          according to law, or, if any assignment shall be made of Lessee's
          property for the benefit of creditors, then the Lessor shall have
          the right thereafter, while such default continues, to re-enter
          and take complete possession of the Premises, to declare the Term
          of this Lease ended, and remove the Lessee's effects without
          prejudice to any remedies which might be otherwise used for
          arrears of rent or other default.  The Lessee shall indemnify the
          Lessor against all loss of rent and other payments which the
          Lessor may incur by reason of such termination during the residue
          of the term.  If the Lessee shall default, after reasonable
          notice thereof, in the observance or performance of any
          conditions or covenants or Lessee's part to be observed or
          performed under or by virtue of any of the provisions in any
          article of this lease, the Lessor, without being under any
          obligation to do so and without thereby waiving such default, may
          remedy such default for the account and at the expense of the
          Lessee.  If the Lessor makes any expenditures or incurs any
          obligations for the payment of money in connection therewith,
          including but not limited to reasonable attorney's fees, in
          instituting, prosecuting or defending any action or legal
          proceeding, such sums paid or obligations incurred, with interest
          at the rate of eighteen percent (18%) per annum and costs, shall
          be paid to the Lessor by the Lessee as damages for Lessee's
          breach.

               26.  NOTICE TO PARTIES.  Any notice from the Lessor to the
          Lessee relating to the Premises or to the occupancy thereof
          (including but not limited to any notice of default or
          termination pursuant to Section 24, or any legal process relating
          thereto for possession or for rent due), shall be deemed duly
          served, if mailed to the Premises, to the attention of the
          President, registered or certified mail, return receipt
          requested, postage prepaid, addressed to the Lessee.

               Any notice from the Lessee to the Lessor relating to the
          Premises or to the occupancy thereof, shall be deemed duly
          served, if mailed to the Lessor by registered or certified mail,
          return receipt requested, postage prepaid, at 400 Amherst St.,
          Suite 202, Nashua, NH 03063.

               27.  LIMITATION OF LIABILITY.  In the event Lessor shall
          default in the performance of its obligations hereunder, Lessee
          shall look only to Lessor's then equity interest in the Building
          for the satisfaction of any judgement; and in no event shall
          Lessor be liable for any consequential damages.  In the event of
          any sale of the Premises or Lessor s assignment of this Lease,
          the Lessor shall be and hereby is entirely released and
          discharged from any and all further liability and obligations of
          the Lessor hereunder, except for such thereof as may have
          theretofore accrued.

               28.  SURRENDER.  The Lessee shall at the expiration or other
          termination of this Lease remove all Lessee's goods and effects
          from the Premises, including, without hereby limiting the
          generality of the foregoing, all signs and lettering affixed or
          painted by the Lessee, either inside or outside the Premises. 
          Lessee shall deliver to the Lessor the Premises and all keys,
          locks thereto, and other fixtures connected therewith and all
          alterations and additions made to or upon the leased premises, in
          good condition, damage by fire or other casualty only excepted. 
          In the event of the Lessee's failure to remove any of Lessee's
          property from the Premises, Lessor is hereby authorized, without
          liability to Lessee for loss or damage thereto, and at the sole
          risk of Lessee, to remove and store any of the property at
          Lessee's expense, or to retain same under Lessor s control or to
          sell at public or private sale without notice any or all of the
          property not so removed and to apply the net proceeds of such
          sale to the payment of any sum due hereunder, or to destroy such
          property.

               29.  LESSOR'S FAILURE TO ACT UPON LESSEE'S BREACH.  The
          failure of the Lessor to insist in any one or more instances upon
          a strict performance or observance of any of the terms,
          provisions or covenants of the Lease or to exercise any right
          therein contained shall not be construed or deemed to be a waiver
          or relinquishment for the future of such terms, provisions,
          covenant or right; but the same shall continue and remain in full
          force and effect.  Receipt by the Lessor of rent with knowledge
          of the breach of any provision of the foregoing Lease shall not
          be deemed a waiver of such breach.

               30.  SERVICES PROVIDED BY LESSOR.  With respect to any
          services to be furnished to Lessee, the Lessor shall in no event
          be liable for failure or delay to furnish the same when prevented
          from so doing by war, strikes, labor difficulties, lockouts,
          breakdown, accident, order or regulation of governmental
          authority, failure of supply, or inability by exercise of
          reasonable diligence, to obtain supplies, parts or employees
          necessary to perform such services, or for any cause beyond
          Lessor s reasonable control, or of any cause due to any act or
          neglect on the part of the Lessee or its servants, agents,
          employees, licensees or any person claiming by, through or under
          the Lessee.

               31.  ASSIGNMENT, SUBLETTING.  Lessee shall not assign,
          mortgage, pledge, or otherwise encumber this Lease or sublet the
          Premises (or any portion thereof) without first obtaining the
          written consent of the Lessor.  Notwithstanding any assignment or
          subletting hereunder, Lessee shall continue to be liable for the
          performance and/or observance of the covenants, agreements,
          terms, and provisions of this Lease.  If the Lessee is a
          corporation or a trust, the sale or transfer at any time during
          the term of this Lease of more than fifty percent (50%) of the
          corporate stock or of the beneficial interest of the trust shall
          be deemed an assignment of the Lease requiring Lessor s prior
          written consent.

               32.  CERTIFICATE OF ESTOPPEL.  The Lessee shall, at the
          request of the Lessor, provide to whomsoever the Lessor shall
          name, a Certificate of Estoppel regarding the terms, covenants,
          and conditions of the Lease.

               33.  MARGINAL HEADINGS.  The marginal headings appearing in
          this Lease are for purposes of easy reference and shall not be
          considered a part of this Lease or in any way to modify, to
          amend, or to affect the provisions thereof.

               34.  ENTIRE AGREEMENT.  This Lease and any exhibit attached
          hereto and forming a part hereof sets forth all of the covenants,
          promises, agreements, conditions and understandings between
          Lessor and Lessee concerning the Premises and there are no
          covenants, promises, agreements, conditions or understandings,
          either oral or written, between them other than herein set forth. 
          No subsequent alteration, amendment, change or addition to the
          Lease shall be binding upon Lessor or Lessee unless reduced to
          writing and signed by them.

               35.  HEIRS, EXECUTORS, ETC.  The covenants, conditions and
          agreements contained in this Lease shall bind and enure to the
          benefit of Lessor and Lessee and their respective heirs,
          distributees, executors, administrators, successors and assigns,
          except as otherwise provided in this Lease.

               36.  REPRESENTATION AS TO BROKERS.  Lessee materially
          warrants and represents to Lessor that it has dealt with no
          broker or agent in connection with this transaction other than
          Hirsch & Company, Inc. and Lessee agrees to indemnify and hold
          Lessor harmless from and against any cost, liability or damage
          including reasonable attorney's fees and expenses) incurred by
          Lessor arising from a claim by any person or firm other than
          Hirsch & Company, Inc. alleging entitlement to a broker's
          commission or finder s fee for the rental of the Premises.

               37.  JOINT AND SEVERAL LIABILITY.  If Lessee shall at any
          time comprise or include more than one person, firm, corporation
          or entity, the liability of each thereof shall be joint and
          several.

               38.  GOVERNING LAW.  This Lease shall be construed and
          interpreted in accordance with the laws of the State of New
          Hampshire.

               39.  PREPARATORY WORK

               (a)  Lessor shall perform in a diligent, workmanlike manner
          at its sole cost and expense the renovation of the Premises in
          accordance with the specifications set forth in Exhibit B
          attached hereto.

               (b)  Lessee shall perform in a diligent, workmanlike manner

          accordance with the specifications set forth in Exhibit C
          attached hereto.

               (c)  In connection with the plans and construction

               40.  RECORDING.  Lessee shall not record this Lease in any
          Registry of Deeds or public registration office.  Any recording
          of this Lease shall constitute a material breach by Lessee,
          entitling Lessor, at its election, to immediately terminate this
          Lease.

               41.  COMPLIANCE WITH ADA.  If the Premises are now, or at
          any time during the Lease Term become a  Public Accommodation 
          under the Americans with Disabilities Act of 1990 (hereinafter
          "ADA"), Lessee shall at its sole expense be responsible for (a)
          compliance with Title III of the ADA to the extent that the ADA
          imposes obligations on the procedure and design of any
          alterations to the Premises made by Lessee, including but not
          limited to partitions, furnishings, doors, door frames and all
          accessories thereof, and (b) drawing and implementing
          modifications in its policies, practices and procedures in
          connection with the operation of Lessee's business and occupancy
          of the Premises.  If Lessee fails to comply with its obligations
          hereunder and such noncompliance constitutes a violation of the
          ADA, Lessee shall indemnify and hold harmless Lessor from and
          against all claims, expenses or liability suffered or incurred by
          Lessor resulting therefrom.

               42.  SECURITY DEPOSIT.  Coincidental with the execution of
          this Lease, Lessee shall deliver to Lessor a security deposit in
          the amount of $3,827.98 which shall be held in security for
          Lessee's full, faithful and diligent performance under this
          Lease.  Said deposit shall be non-interest bearing and shall be
          refunded to Lessee at the expiration of the Lease, subject to
          Lessee's satisfactory compliance with the terms and conditions
          hereof.

               43.  OPTION TO EXTEND LEASE Lessee shall have the option to
          extend the term of the Lease for one additional term of three (3)
          years provided that: (a) Lessee is not in default (beyond the
          expiration of any grace period granted herein for the curing of
          same) under any of the terms and conditions of the Lease at the
          time it elects to extend the term and at the commencement of the
          Extension Term, and (b) Lessee has given Lessor written notice of
          its election to extend the term no later than six months prior to
          the Expiration Date of the Lease.  In the event that Lessee shall
          extend the term as aforesaid, such extension shall be upon the
          same terms and conditions as set forth herein, except that no
          further right to extend shall be deemed to be included, and
          except for the Base Rent, which shall be determined as
          hereinafter set forth.

               The Base Rent during the Extension Term shall be the Base
          Rent in effect during the last year of the Term or the "Market
          Rent" (as hereinafter defined), whichever is greater.  The term
          "Market Rent" shall mean the rent being charged for comparable
          existing space at the time the extension option is exercised, as
          reasonably determined by the Lessor.  Lessor shall send a written
          notice to Lessee specifying the rent for the extension term
          within thirty (30) days of its receipt of Lessee's exercise of
          option to extend.  Lessee shall be deemed to have rejected the
          new rent level if it has not sent Lessor a notice approving the
          same within ten (10) days of receipt of Lessor s notice.  In the
          event Lessee disapproves the new rent level, then  Market Rent 
          shall be determined as follows:

               Each party shall within ten (10) days of Lessee's
          disapproval appoint an arbitrator to act on its behalf, which
          person shall be a real estate broker or other person experienced
          in the appraisal or management of real estate within the Nashua
          metropolitan area.  If the two arbitrators are unable to reach
          agreement within ten (10) days after their appointment, then the
          two arbitrators shall appoint a third arbitrator and the decision
          by a majority of the arbitrators shall be binding upon the
          parties.  Each party shall each bear the cost of the arbitrators
          selected by it and shall jointly bear the cost of any third
          arbitrator.  In the event the arbitrators have failed to
