liability company, 801 Grand Avenue, Des Moines, IA 50392-1370, ("Landlord"),
and Teledigital Inc., a Minnesota corporation, whose address for the purpose of
this lease ("Lease") shall be 1325 East 79th Street, Suite 6, Bloomington, MN
55425 , ("Tenant").

IT IS AGREED AS FOLLOWS:

1. DEMISE.

         Landlord does hereby lease to Tenant and Tenant hereby rents the
         premises ("Premises") described as: 5,106 square feet of net rentable
         area consisting of approximately 4,436 square feet of office space and
         670 square feet of warehouse space located at 1325 East 79th Street,
         Suite 6, Bloomington, MN 55425 which, more particularly, includes the
         space and Premises shown on the site plan attached hereto and marked
         Exhibit "A".

         Improvements. Landlord or shall prepare and furnish the drawings and
         specifications as needed for all improvements set forth in Exhibit "B"
         which is attached hereto and made a part hereof. The total cost for
         space planning, construction drawings, the actual construction and
         construction management is to be paid by Landlord up to a maximum
         amount of $0.00 ("Allowance"). In the event total costs exceed the
         Allowance, Tenant shall be responsible for paying to Landlord within 30
         days of the lease commencement date, costs exceeding the Allowance or,
         at the sole option of Landlord, execute a lease amendment providing for
         an increase in Base Rent over the lease term equal to the costs that
         exceed the Allowance when amortized at 14 %.

2. TERM.

         The term of this Lease shall be for a period of Five (5) years,
         commencing on the 1st day of January, 2000 and ending at midnight on
         the 31st day of December, 2004 ("Lease Term"). Notwithstanding said
         commencement date, if for any reason Landlord cannot deliver possession
         of the leased Premises to the Tenant on or by January 1, 2000, Tenant
         shall not be obligated to pay rent until possession of the Premises is
         tendered to Tenant. In such event, the term of the Lease shall be
         extended so that the term remains Sixty (60) months. If the leased
         Premises are delivered on a date other than the 1st day of the month,
         rent for that month shall be prorated and the term extended for the
         full term from the first day of the following month. In the event that
         the delay of delivery of possession results from Tenant's failure to
         perform work for which Tenant is responsible, or fails to furnish or
         approve, as agreed, the plans and specifications as provided above, or
         fails to make timely selections of materials, color choices or other
         matters for which Tenant is responsible, the rent shall, nonetheless,
         commence on the commencement date stated above. If Tenant occupies the
         Premises prior to said commencement date, such occupancy shall be
         subject to all provisions hereof and shall not advance the termination
         date, and Tenant shall pay rent for such period at the initial monthly
         rate set forth below.

3. RENT.

         (A) Rent. Tenant shall pay for the use and occupancy of the Premises a
         base rental (Rent) sum, payable in equal monthly installments on the
         first day of each month in advance without demand during the Lease
         Term. Tenant's base rental sum during the Lease shall be paid as
         follows:

                                                                    Monthly
                                                                    -------
             January 1, 2000 - December 31, 2004                  $4,106.08

         Rent of any period during the Lease Term hereof which is less than one
         month shall be a pro-rata portion of the monthly installment. Rent
         shall be payable in lawful money of the United States to Landlord at
         the address stated herein or to such other persons or at such other
         places as Landlord may designate in writing.

         (B) Place of Payment. All such rentals shall be paid to Landlord at CB
         Richard Ellis, PO Box 1450, NW 7196-5650, Minneapolis, MN 55485-7196 or
         at such place as Landlord may designate from time to time, in writing
         addressed to Tenant.

         (C) Late Charge. Tenant hereby acknowledges that late payment by Tenant
         of Rent or other sums due thereunder will cause Landlord to incur costs
         not contemplated by this Lease. Therefore, if any installment of Rent
         or any other sum due from Tenant shall not be received by Landlord
         within ten (10) days after such amount is due, Tenant shall pay to
         Landlord a late charge of six percent (6%) of such overdue amount.
         Acceptance of such late charge by Landlord shall in no event constitute
         a waiver of Tenants default with respect to such overdue amount or
         prevent Landlord from exercising any other right or remedy available to
         Landlord.

         (D) Receipt. Receipt is hereby acknowledged of the sum of $0.00 in
         payment of the monthly base and operating expense Rents for the first
         month of the Lease Term.

         (E) Security Deposit. Tenant shall deposit with Landlord upon execution
         hereof $5,752.76 as security for Tenant's faithful performance of
         Tenant's obligations hereunder. If Tenant fails to pay Rent or other
         charges due hereunder or otherwise defaults with respect to any
         provision of the Lease, Landlord may use, apply or retain all or any
         portion of said deposit for the payment of any Rent or other charge in
         default or for the payment of any other sum to which Landlord may
         become obligated by reason of Tenant's default, or to compensate
         Landlord for any loss or damage which Lessor may suffer thereby. If
         Landlord so uses or applies all or any portion of said deposit, Tenant
         shall within ten (10) days after written demand therefor deposit cash
         with Landlord in an amount sufficient to restore said deposit to the
         full amount herein above stated and Tenant's failure to do so shall be
         a material breach of this Lease. If the monthly Rent shall, from time
         to time increase during the Lease Term, Tenant shall thereupon deposit
         with Landlord additional security deposit so that the amount of
         security deposit held by Landlord shall at all times bear the same
         proportion to current rent as the original security deposit bears to
         the original monthly Rent set forth in Paragraph 3A

                                                                   EXHIBIT 10.26


         hereof. Landlord shall not be required to keep said deposit separate
         from its general accounts. If Tenant performs all of Tenant's
         obligations hereunder, said deposit, or so much thereof as has not
         theretofore been applied by Landlord shall be returned, without payment
         of interest or other increment for its use to Tenant (or at Landlord's
         option, to the last assignee, if any, of Tenant's interest hereunder)
         at the expiration of the Lease Term hereof and after Tenant has vacated
         the Premises. No trust relationship is created herein between Landlord
         and Tenant with respect to said Security Deposit.

         Tenant hereby agrees not to look to any mortgagee as mortgagee,
         mortgagee-in-possession or successor in title to the Premises for
         accountability for any security deposit required by Landlord hereunder,
         unless said sums have actually been received by said mortgagee as
         security for Tenant's performance of this Lease. Landlord may deliver
         the funds deposited hereunder by Tenant to the purchaser of Landlord's
         interest in the Premises, in the event that such interest is sold, and
         thereupon Landlord shall be discharged from any further liability with
         respect to said security deposit.

         (F) Pro Rata Share. Tenant's proportionate share shall be the
         percentage which the square footage of the Premises bears to the total
         square footage of the following-described building(s) Olympia Business
         Center (54,794 square feet)

4. PERMITTED USE.

         Tenant covenants that the Premises will be used as general office and
         warehouse ("Permitted Use") together with the incidental activities of
         Tenant, its affiliated companies or other subsidiary companies and for
         no other use or purpose. Tenant further covenants that the Premises
         will not be used or occupied for any unlawful purposes. Tenant agrees
         to and shall use the Premises solely for the purpose of conducting the
         Permitted Use and for no other business or purpose. Tenant also agrees
         not to conduct any catalogue, mail or telephone order sales in or from
         the Premises, except of merchandise which Tenant is permitted to sell
         "over the counter" in the Premises. Tenant agrees to conduct Tenant's
         business in the Premises under Tenant's Trade Name, which Tenant
         represents that it has the right to use. Tenant acknowledges that the
         Permitted Use is not a use granted exclusively to Tenant and that
         Landlord reserves the right to lease premises in the building to others
         for the same or a similar Permitted Use. Tenant further acknowledges
         that it has received no written or oral inducements from Landlord or
         any of Landlord's representatives concerning this Lease (other than as
         specifically set forth herein) or that Tenant will be granted any such
         exclusive rights. Tenant further covenants that the Premises will not
         be used or occupied for any unlawful purposes. The Tenant will not make
         or permit to be made any use of the Premises or any part thereof which
         would violate any of the covenants, agreements, terms, provisions and
         conditions of this Lease or which directly or indirectly is forbidden
         by public law, ordinance or governmental regulation; or make or permit
         any use of the Premises which may be dangerous, noxious or offensive or
         create or maintain any nuisance or disturbance in, at or on the
         Premises; or make or permit any use of the Premises which may
         invalidate, or increase the premium cost of any policy of insurance
         carried on the Building and

         Expenses."

6. ADDITIONAL RENT (NET CLAUSE).

         It is understood that the Rent set forth in paragraph 3 of the Lease
         was negotiated in anticipation that the Tenant pays for a pro-rata
         share of the Operating Expenses not paid directly by Tenant, defined in
         paragraph 5 of the Lease. Therefore, in order that Rent payable
         throughout the term of this Lease shall reflect such costs, Tenant
         shall pay its pro-rata share of the Operating Expenses defined in
         paragraph 5 which are estimated to be $3.67 per square foot per annum
         or One thousand Five Hundred Sixty One and 59/100 ($1,561.59) per month
         in 1999. At the beginning of the Lease Term and within 60 days after
         the first day of each calendar year, Landlord shall furnish to Tenant
         an estimate of Tenant's pro-rata share of Operating Expenses, not paid
         directly by Tenant, defined in Paragraph 5 for the ensuing calendar
         year. Tenant shall pay to Landlord 1/12th of said estimate at the same
         time and place as the base rent is to be paid pursuant to paragraph 3,
         above. Landlord will furnish a statement of the actual cost with
         respect to the reimbursable expenses no later than sixty (60) days
         following the calendar year-end including the year following the year
         in which the Lease terminates. In the event that Landlord is, for any
         reason, unable to furnish the accounting for the prior year within the
         time specified above, the Landlord will furnish such accounting as soon
         thereafter as practicable with the same force and effect as the
         statement would have had if delivered within the time specified above.
         Tenant will pay any deficiency to Landlord as shown by such statement
         within thirty (30) days after receipt of statement. If the total amount
         paid by Tenant during any calendar year exceeds the actual amount of
         its share of the Operating Expenses due for such calendar year, the
         excess will be refunded by Landlord within thirty (30) days of the date
         of the statement. Landlord will keep books and records showing the
         Operating Expenses in accordance with generally accepted accounting
         principles. Upon five (5) business days notice, Tenant shall have the
         right to inspect the books and records at the office of the Landlord or
         its Manager.

7. REPAIRS AND MAINTENANCE

         Notwithstanding anything to the contrary contained herein, the Tenant
         will keep, maintain and preserve the Premises in a first class
         condition. The Tenant at its sole cost and expense will provide
         janitorial and window washing for the interior of the Premises. In
         addition, Tenant shall be responsible for all utility services for
         which the Tenant is separately metered. When and if needed, at the
         Tenant's sole cost and expense, the Tenant will make all interior
         repairs and replacements including but not limited to interior walls,
         doors and windows, floors, floor coverings, light bulbs, plumbing
         fixtures, heating/air conditioning systems, hot water systems, and
         electrical fixtures. Tenant shall also make all repairs and
         replacements to Tenant's overhead garage and exterior pedestrian doors.
         The Tenant will also repair and replace at its sole cost and expense
         any broken windows and/or damage to the building or Premises caused by
         the negligence of the Tenant or its employees, agents, guests or
         invitees during the Lease Term hereof. The above repairs, replacements,
         and/or services must be performed by an approved contractor of the
         Landlord. Should Tenant fail to perform all interior repairs and
         replacements to Tenant's Premises such repairs may be performed by the
         Landlord and charged to the Tenant at the Tenant's sole cost and
         expense. Tenant will comply with all ordinances of the City of
         Bloomington, rules and regulations of the Board of Health and the laws
         of the State of Minnesota. The tenant is also responsible for
         compliance with all laws, rules and regulations of any governmental
         authority required of either the Landlord or the Tenant relative to the
         repair, maintenance and replacement in the Premises.

8. SORTING AND SEPARATION OF REFUSE AND TRASH.

         (A) The Tenant covenants and agrees, as its sole cost and expense, to
         comply with all present and future laws, orders and regulations of all
         state, federal, municipal and local governments, departments,
         commissions and boards regarding the collection, sorting, separation
         and recycling of waste products, garbage, refuse and trash. The Tenant
         shall sort and separate waste products, garbage, refuge and trash into
         such categories as provided by law. Each separately sorted category of
         waste products, garbage, refuse and trash shall be placed in separate
         receptacles reasonably approved by the Landlord. Such separate
         receptacles may, at the Landlord's option, be removed from the Premises
         in accordance with a collection schedule prescribed by law.

         (B) The Landlord reserves the right to refuse to collect or accept from
         the Tenant any waste products, garbage, refuse or trash that is not
         separated and sorted as required by law, and to require the Tenant
         arrange for such collection at the Tenant's sole cost and expense,
         utilizing a contractor satisfactory to the Landlord. The Tenant shall
         pay all costs, expenses, fines, penalties or damages that may be
         imposed on the Landlord or the Tenant by reason of the Tenant's failure
         to comply with the provisions of this paragraph 8B, and, at the
         Tenant's sole cost and expense, shall indemnify, defend and hold the
         Landlord harmless (including legal fees and expenses) from and against
         any actions, claims and suits arising from such noncompliance,
         utilizing counsel reasonably satisfactory to the Landlord.

         The term "Hazardous Substances", as used in this lease shall mean
         pollutants, contaminants, toxic or hazardous wastes, or any other
         substances, the use and/or the removal of which is required or the use

         by any governmental agency; (C) no portion of the Premises will be used
         as a landfill or a dump; (D) Tenant will not install any underground
         tanks of any type; (E) Tenant will not allow any surface or subsurface
         conditions to exist or come into existence that constitute, or with the
         passage of time may constitute a public or private nuisance; (F) Tenant
         will not permit any Hazardous Substances to be brought onto the
         Premises, except for the Permitted Materials described above, and if so

         shall be diligently undertaken pursuant to all Environmental Laws.
         Landlord or Landlord's representative shall have the right but not the
         obligation to enter the Premises for the purpose of inspecting the
         storage, use and disposal of Permitted Materials to ensure compliance
         with all Environmental Laws. Should it be determined, in Landlord's
         sole opinion, that said Permitted Materials are being improperly

         after the term of the Lease Term, the Premises are found to be so
         contaminated or subject to said conditions, Tenant shall diligently
         institute proper and thorough cleanup procedures at Tenant's sole cost,
         and Tenant agrees to indemnify, defend and hold harmless Landlord, its

         termination or expiration of this Lease.

         During the Lease Term, Tenant shall promptly provide Landlord with

                  Such insurance shall have a combined single limit of not less
                  than One Million Dollars ($1,000,000) per occurrence per

                  The minimum limited specified above are the minimum amounts

                  to time to meet changed circumstances, including without

                  thereto.

                  (3) Other. Such other insurance as required by law, including,
                  without limitation, workers' compensation insurance.

                  (4) Form of the Policies. The policies required to be
                  maintained by Tenant pursuant to Paragraphs 10(B)(l), (2), and

                  Minnesota and domiciled in USA, on forms, with deductible
                  amounts (if any), and loss payable clauses satisfactory to
                  Landlord, shall include Landlord and the beneficiary or
                  mortgagee of any deed of trust or mortgage encumbering the
                  Premises as additional insureds, and shall provide that such
                  parties may, although additional insureds, recover for any
                  loss suffered by Tenant's negligence. Certified copies of
                  policies or certificates of insurance shall be delivered to

                  Tenant shall have the right to provide insurance coverage
                  which it is obligated to carry pursuant to the terms hereof in
                  a blanket policy, provided such blanket policy expressly
                  affords coverage to the Premises and to Tenant as required by
                  this Lease. Tenant shall obtain a written obligation on the
                  part of Tenant's insurer(s) to notify Landlord and any
                  beneficiary or mortgagee of a deed of trust or mortgage
                  encumbering the Premises in writing of any delinquency in
                  premium payments and at least thirty (30) days prior to any

                                       9
<PAGE>


                                                                   EXHIBIT 10.26


                  fails to deliver to Landlord a current certificate(s)
                  evidencing that the insurance required hereunder is being
                  maintained. Each such policy and certificate shall provide for
                  at least thirty (30) days prior written notice to Landlord in
                  the event of cancellation.

         (C) FAILURE BY TENANT TO OBTAIN INSURANCE.

                  If Tenant does not take out the insurance required pursuant to
                  Paragraph 10(B) or keep the same in full force and effect,
                  Landlord may, but shall not be obligated to take out the
                  necessary insurance and pay the premium therefor, and Tenant
                  shall repay to Landlord, as additional Rent, the amount so
                  paid promptly upon demand. In addition, Landlord may recover
                  from Tenant and Tenant agrees to pay, as additional Rent, any
                  and all reasonable expenses (including attorneys' fees) and
                  damages which Landlord may sustain by reason of the failure to
                  Tenant to obtain and maintain such insurance, it being
                  expressly declared that the expenses and damages of Landlord
                  shall not be limited to the amount of the premiums thereon.

         (D) SUBROGATION.

                  In the event of loss or damage to the Premises, each party
                  will look first to any insurance in its favor before making
                  any claim against the other party. The Tenant will obtain for
                  each policy in effect a provision permitting waiver of any
                  claim against the Landlord for loss or damage within the scope
                  of the insurance. In addition, each party, its agents,
                  employees or guests to the extent permitted, for itself and
                  its insurers waives all such insured claims against the other
                  party.

11. DAMAGE OR RESTORATION.

         If, prior to or during the Lease Term, or any extension thereof, the
         Premises or the building of which the Premises may be a part, shall be
         so damaged or destroyed by fire or other casualty so as to render them
         untenantable for the purposes set forth in Paragraph 4 hereof, then
         Landlord, at its sole option, shall have the right to cancel and
         terminate this Lease. If not terminated, then Landlord shall repair and
         restore the Premises with all reasonable speed to substantially the
         same condition as immediately prior to such damage or destruction, and
         the Rent or a just and proportionate part thereof, according to
         Tenant's ability to utilize the Premises in its damaged condition,
         shall be abated until the Premises shall have been repaired and
         restored by Landlord. But if the Premises shall be so lightly damaged
         by fire or other casualty as not to be rendered untenantable, then
         Landlord agrees to repair the Premises with reasonable promptness and
         the rent accrued and accruing, shall not cease. "Untenantable" Premises
         shall be such as to not allow Tenant to transact and effectuate its
         operations in the ordinary course of business.

12. INDEMNIFICATION.

         Tenant shall indemnify, hold harmless, and defend Landlord (except for
         Landlord's gross negligence or willful misconduct) against all claims,
         losses or liabilities for injury or death to any person or for damage
         to or loss of use of any property arising out of any occurrence in, on
         or about the Building or land, if caused or contributed to by Tenant or


                                       10

                                                                   EXHIBIT 10.26


         Tenant's agents, or arising out of any occurrence in, upon or at the
         Premises or on account of the use, condition, occupational safety or
         occupancy of the Premises. It is the intent of the parties hereto that
         the indemnity contained in this Paragraph shall not be limited or
         barred by reason of any negligence on the part of Landlord or
         Landlord's agents, except as expressly provided herein. Such
         indemnification shall include and apply to attorneys' fees,
         investigation costs, and other costs actually incurred by Landlord.
         Tenant shall further indemnify, defend and hold harmless Landlord from
         and against any and all claims arising from any breach or default in
         the performance of any obligation on Tenant's part to be performed
         under the terms of this Lease. The provisions of this Paragraph shall
         survive Lease Termination with respect to any damage, injury, death,
         breach or default occurring prior to such termination. This Lease is
         made on the express conditions that Landlord shall not be liable for,
         or suffer loss by reason of, injury to person or property, from
         whatever cause, in any way connected with the condition, use,
         occupational safety or occupancy of the Premises specifically
         including, without limitation, any liability for injury to the person
         or property of Tenant or Tenant's agents.

13. ASSIGNMENT AND SUBLETTING.

         Tenant may assign, sublet or transfer this Lease to any person, firm or
         corporation with the written consent of Landlord which consent shall
         not be unreasonably withheld, provided, however, that no such
         assignment, sublease or transfer shall act as a release of Tenant from
         any of the obligations and agreements on its part to be kept and
         performed hereunder. Any assignment, sublease or transfer without the
         prior written consent of Landlord shall be null and void at Landlord's
         option. Landlord's approval of any subtenant or assignee is conditioned
         upon there being no additional compliance required with any laws, rules
         and regulations of any governmental authority required of either the
         Landlord or the Tenant and such approval shall create no responsibility
         or liability on the part of the Landlord for any non-compliance with
         laws, rules and regulations of any governmental authority.

         Request for consent to assign Tenant's interest or to sublease the
         Premises shall be accompanied by a statement setting forth the name of
         the prospective assignee or sublessee, the financial details of the
         assignment or sublease (i.e. the rental and security deposit), the
         term, other relevant information concerning the proposed assignee or
         sublessee. Landlord shall have the right within ten (10) days after
         receipt of such written request from Tenant to (A) withhold consent to
         the assignment or sublease if the withholding of such consent is
         reasonable, or (B) consent to such sublease or Assignment, in which
         case any rent payable by the assignee or sublessee (including any lump
         sum of additional payment or other consideration for the assignment or
         sublease) which exceeds the rent payable by Tenant hereunder shall be
         shared fifty percent (50%) by Tenant and fifty percent (50%) by
         Landlord, or (C) terminate this Lease, effective as of the commencement
         date of the term of such sublease or the effective date of such
         assignment in which case Landlord shall have the right to enter into a
         direct Lease with such proposed assignee or sublessee. If Landlord
         elects to so terminate the Lease, then this Lease shall be canceled and
         terminated as of the effective date of the proposed


                                       11

                                                                   EXHIBIT 10.26


         assignment or the commencement date of the proposed sublease, as set
         forth in Tenant's notice.

14. CARE OF PREMISES.

         Tenant further covenants and agrees that during said Lease Term it will
         keep said Premises and every part thereof and all buildings at any time
         situated thereon in a clean and wholesome condition and generally that
         it will in all respects and at all times duly comply with all lawful
         health and police regulations and also that it will keep the
         improvements at any time situated upon the Premises safe, secure and
         comfortable to the lawful and valid requirements applicable thereto.

15. ALTERATION BY TENANT.

         (A) Tenant is hereby given the right, at its sole cost and expense, at
         any time during the term hereof, to make any alterations or
         improvements to the interior of the demised premises which the Tenant
         may deem necessary or desirable for its purposes; provided, however,
         that no alterations or improvements shall be made without the written
         approval of the Landlord, which written approval shall not be
         unreasonably withheld. Landlord's approval of any plans, specifications
         or work drawings shall create no responsibility or liability on the
         part of the Landlord for their completeness, design sufficiency or
         compliance with any laws, rules and regulations of governmental
         agencies or authorities.

         (B) All work herein permitted shall be done and completed by the Tenant
         in a good and workmanlike manner and in compliance with all
         requirements of law and of governmental rules and regulations. Tenant
         agrees to indemnify the Landlord against all mechanics' or other liens
         arising out of any of such work, and also against any and all claims
         for damages or injury which may occur during the course of any such
         work. The Landlord agrees to join with the Tenant in applying for all
         permits necessary to be secured from governmental authorities and to
         promptly execute such consents as such authorities may require in
         connection with any of the foregoing work.

         (C) Landlord may require that Tenant remove any or all said
         alterations, improvements or additions at the expiration of the term,
         and restore the Premises to their prior condition. Unless Landlord
         requires their removal, all alterations, additions and improvements
         which may be made on the Premises, shall become the property of
         Landlord and remain upon and be surrendered with the Premises at the
         expiration of the Lease Term. Tenant shall repair any damage to the
         Premises caused by the installation or removal of Tenant's trade
         fixtures, furnishings and equipment.

16. CONDEMNATION.

         (A) If the leased Premises shall be wholly taken by exercise of right
         of eminent domain, then this Lease shall terminate from the day the
         possession of the whole of the Premises shall be required under the
         exercise of such power of eminent


                                       12
<PAGE>


                                                                   EXHIBIT 10.26


         domain. Any award for the taking of all or part of the Premises under
         the power of eminent domain or any payment made under threat of the
         exercise of such power shall be the property of the Landlord. Tenant
         reserves such separate rights as it may have against the condemning
         authority to claim damages for loss of its trade fixtures and the cost
         of removal and relocation expenses.

         (B) If such part of the building or buildings in which Tenant's
         business is operated shall be condemned so as to the substantially and
         materially hamper the operation of Tenant's business, then the Rent
         payable hereunder shall be reduced in the proportion that the remaining
         area of the Premises bears to the original area of the entire Premises
         leased hereunder. If the parties are unable to agree upon the amount of
         the reduction in Rent within seven (7) days from the date the Tenant's
         business is substantially and materially hampered, then it shall be
         arrived at by arbitration, each party to select an arbitrator and if
         the two arbitrators are unable to agree they shall select a third
         arbitrator and the three arbitrators so selected shall determine the
         amount of such reasonable reduction. It is agreed that the findings of
         the arbitrators shall be binding upon the parties.

17. SUBORDINATION.

         Tenant shall, upon the written request of Landlord, agree to the
         subordination of this Lease and the lien hereof to the lien of any
         present or future mortgage upon the premises irrespective of the time
         of execution or the time of recording of any such mortgage. In the
         event of subordination of this Lease, Landlord will attempt to obtain
         from the holder of any such mortgage, a written agreement with Tenant
         to the effect that (A) in the event of a foreclosure or other action
         taken under the mortgage by the holder thereof, this Lease and the
         rights of Tenant hereunder shall not be disturbed but shall continue in
         full force and effect so long as Tenant shall not be in default
         hereunder; and (B) such holder will agree that in the event it or any
         successor assign shall be in possession of the premises, that so long
         as Tenant shall observe and perform all of the obligations of Tenant to
         be performed pursuant to this Lease, such Mortgagee will perform all
         obligations of Landlord required to be performed under this Lease. The
         word "Mortgage" as used herein includes mortgages, deeds of trust and
         any sale-leaseback transactions, or other similar instruments, and
         modifications, extensions, renewals, and replacements thereof, and any
         and all advances thereunder.

18. ACCESS TO PREMISES

         Landlord and its authorized agents shall have free access to said
         Premises at any and all reasonable times to inspect the same and for
         the purposes pertaining to the rights of the Landlord.

19. RULES AND REGULATIONS.

         Tenant agrees to comply with all rules and regulations promulgated by
         Landlord concerning the use and enjoyment of the Premises. Among other
         things, the rules and regulations specifically prohibit outdoor
         storage.

20. COVENANTS OF RIGHT TO LEASE.

         Landlord covenants that it has good and sufficient right to enter into
         this Lease and that they alone have full right to lease the Premises
         for the Lease Term aforesaid. Landlord further covenants that upon
         performing the terms and obligations of Tenant under this Lease, Tenant
         will have quite enjoyment throughout the Lease Term and any renewal or
         extension thereof.

21. MECHANIC'S LIENS.

         Neither the Tenant nor anyone claiming by, through, or under the lease,
         shall have the right to file or place any mechanic's lien or other lien
         of any kind or character whatsoever upon said Premises or upon any
         building or improvement thereon, or upon the leasehold interest of the
         Tenant therein, and notice is hereby given that no contractor,
         subcontractor, or anyone else who may furnish any material, service or
         labor for any building, improvements, alteration repairs or any part
         thereof, shall at any time be or become entitled to any lien thereon,
         and for the further security of the Landlord, the Tenant covenants and
         agrees to give actual notice thereof in advance, to any and all
         contractors and subcontractors who may furnish or agree to furnish any
         such material, service or labor.

22. EXPIRATION OF LEASE AND SURRENDER OF POSSESSION.

         (A) Holding Over. Tenant will, at the termination of this Lease by
         lapse of time or otherwise, yield up immediate possession to Landlord.
         If Tenant retains possession of the Premises or any part thereof after
         such termination, then Landlord may, at its option, serve written
         notice upon Tenant that such holding over constitutes any one of (i)
         renewal of this Lease for one year, and from year to year thereafter,
         or (ii) creation of a month-to-month tenancy, upon the terms and
         conditions set forth in this Lease, or (iii) creation of a tenancy at
         sufferance, in any case upon the terms and conditions set forth in this
         Lease; provided, however, that the monthly Rent (or daily Rent under
         (iii)) shall, in addition to all other sums which are to be paid by
         Tenant hereunder, whether or not as additional Rent, be equal to double
         the Rent being paid monthly to Landlord under this Lease immediately
         prior to such termination (prorated in the case of (iii) on the basis
         of a 365-day year for each day Tenant remains in possession). If no
         such notice is served, then a tenancy at sufferance shall be deemed to
         be created at the Rent in the preceding sentence. Tenant shall also pay
         to Landlord all damages sustained by Landlord resulting from retention
         of possession by Tenant, including the loss of any proposed subsequent
         tenant for any portion of the Premises. The provisions of this
         paragraph shall not constitute a waiver by Landlord of any right of
         re-entry as herein set forth; nor shall receipt of any Rent or any
         other act in apparent affirmance of the tenancy operate as a waiver of
         the right to terminate this Lease for a breach of any of the terms,
         covenants, or obligations herein on Tenant's part to be performed.

         (B) Upon the expiration of this Lease, by lapse of time or otherwise,
         any and all buildings, improvements or additions erected on said
         Premises by Tenant shall be and become the property of the Landlord
         without any payment therefor and Tenant shall surrender said Premises,
         together with all buildings and improvements thereon, whether erected
         by Tenant or Landlord, ordinary wear and tear and damage by fire or
         other casualty excepted.

         (C) Tenant may install adequate equipment, fixtures and machinery for
         the carrying on of its business and upon the termination of this Lease
         by lapse of time or otherwise, provided all Rents and other amounts
         that may be due and owing to Landlord have been paid and the provisions
         of this Lease complied with, the Tenant may remove such equipment,
         fixtures and machinery installed by it at Tenant's cost. However, upon
         removal of such equipment, fixtures and machinery, the Tenant shall
         also repair any damage caused by such removal or installation.

23. DEFAULT-REMEDIES.

         The occurrence of one or more of the following events shall constitute
         a material default and breach of this Lease by Tenant:

         (A) Failure by Tenant to make payment of any Rent herein agreed to be
         paid or any other payment required to be made by Tenant hereunder, as
         and when due, and such a failure shall continue for a period of ten
         (10) days;

         (B) The making by Tenant of any assignment or arrangement for the
         benefit of creditors;

         (C) The filing by Tenant of a petition in bankruptcy or for any other
         relief under the Federal Bankruptcy Law or any other applicable
         statute;

         (D) The levying of an attachment, execution of other judicial seizure
         upon the Tenant's property in or interest under this lease, which is
         not satisfied or released or the enforcement thereof stayed or
         superseded by an appropriate proceeding within thirty (30) days
         thereafter;

         (E) The filing of an involuntary petition in bankruptcy or for
         reorganization or arrangement under the Federal Bankruptcy Law against
         Tenant and such involuntary petition is not withdrawn, dismissed,
         stayed or discharged within sixty (60) days from the filing thereof;

         (F) The appointment of a Receiver or Trustee to take possession of the
         property of Tenant or of Tenant's business or assets and the order or
         decree appointing such Receiver or Trustee shall have remained in force

         order or decree;

         (G) The vacating or abandonment of the Premises.

                                                                   EXHIBIT 10.26


         (H) The failure by Tenant to perform or observe any other term,
         covenant, agreement or condition to be performed or kept by the Tenant
         under the terms, conditions, or provisions of this lease, and such a
         failure shall continue uncorrected for thirty (30) days after written
         notice thereof has been given by Landlord to the Tenant.

         Then and in any such event Landlord shall have the right, at the option
         of the Landlord, then or at any time thereafter while such default or
         defaults shall continue, to elect either (1) to cure such default or
         defaults at its own expense and without prejudice to any other remedies
         which it might otherwise have, any payment made or expenses incurred by
         Landlord in curing such default with interest thereon at eighteen
         percent (18%) per annum to be and become additional Rent to be paid by
         Tenant with the next installment of Rent falling due thereafter; or (2)
         to re-enter the Premises, without notice, and dispossess Tenant and
         anyone claiming under Tenant by summary proceedings or otherwise, and
         remove their effects, and take complete possession of the Premises and
         either (a) declare this Lease forfeited and the Lease Term ended, or
         (b) elect to continue this Lease in full force and effect, but with the
         right at any time thereafter to declare this Lease forfeited and the
         Lease Term ended. In such re-entry the Landlord may, with or without
         process of law, remove all persons from the Premises, and Tenant hereby
         covenants in such event, for itself and all others occupying the
         Premises under Tenant, to peacefully yield up and surrender the
         Premises to the Landlord. Should Landlord declare this Lease forfeited
         and the Lease Term ended, the Landlord shall be entitled to recover
         from Tenant the Rent and all other sums due and owing by Tenant to the
         date of termination, plus the costs of curing all of Tenant's defaults
         existing at or prior to the date of termination, plus the cost of
         recovering possession of the Premises, plus the deficiency, if any,
         between Tenant's Rent for the balance of the Lease Term provided
         hereunder and the Rent obtained by Landlord under another lease for the
         Premises for the balance of the Lease Term remaining under this lease.
         Landlord shall use its best efforts to rent the Premises with or
         without advertising, and on the best tams available for the remainder
         of the Lease Term hereof, or for such longer or shorter period as
         Landlord shall deem advisable. Tenant shall remain liable for payments
         of all Rent and other charges and costs imposed on Tenant herein, in
         the amounts, at the times and upon the conditions as herein provided,
         but Landlord shall credit against such liability of the Tenant all
         amounts received by Landlord from such reletting after first
         reimbursing itself for all costs incurred in curing Tenant's defaults
         and re-entering, preparing and refinishing the Premises for reletting,
         and reletting the Premises, and for the payment of any procurement fee
         or commission paid to obtain another tenant, and for the attorney fees
         and legal costs incurred by Landlord.

24. RE-ENTRY BY LANDLORD.

         No re-entry by Landlord or any action brought by Landlord to oust
         Tenant from the Premises shall operate to terminate this Lease unless
         Landlord shall have given written notice of termination to Tenant, in
         which event Tenant's liability shall be as above provided. No right or
         remedy granted to Landlord herein is intended to be exclusive of any
         other right or remedy, and each and every right and remedy herein
         provided shall be cumulative and in addition to any other right or
         remedy hereunder or now or hereafter

         existing in law or equity or by statute. In the event of termination of
         this Lease, Tenant waives any and all rights to redeem the Premises
         either given by any statute now in effect or hereafter enacted.

25. ADDITIONAL RIGHTS TO LANDLORD.

         (A) In addition to any and all other remedies, Landlord may restrain
         any threatened breach of any covenant, condition or agreement herein
         contained but the mention herein of any particular remedy or right
         shall not preclude the Landlord from any other remedy or right it may
         have either at law or equity, or by virtue of some other provision of
         this Lease; nor shall the consent to one act, which would otherwise be
         a violation or waiver of or redress for one violation either of
         covenant, promise agreement undertaking or condition, prevent a
         subsequent act which would originally have constituted a violation from
         having all the force and effect of any original violation.

         (B) Receipt by Landlord of Rent or other payments from the Tenant shall
         not be deemed to operate as a waiver of any rights of the Landlord to
         enforce payment of any Rent, additional Rent, or other payments
         previously due or which may thereafter become due, or of any rights of
         the Landlord to terminate this Lease or to exercise any remedy or right
         which otherwise might be available to the Landlord, the right of
         Landlord to declare a forfeiture for each and every breach of this
         Lease is a continuing one for the life of this Lease.

26. SUCCESSORS, ASSIGNS AND LIABILITY.

         The terms, covenants, conditions and agreements herein contained and as
         the same may from time to time hereafter be supplemented, modified or
         amended, shall apply to, bind, and inure to the benefit of the parties
         hereto and their legal representatives, successors and assigns,
         respectively. In the event either party now or hereafter shall consist
         of more than one person, firm or corporation, then and in such event
         all such person, firms and/or corporations shall be jointly and
         severally liable as parties hereunder.

27. NOTICES.

         deemed to be properly served when posted by certified United States
         mail, postage prepaid, return receipt requested, addressed to the party
         to whom directed at the address herein set forth or at such other

28. MORTGAGEE'S APPROVAL.

         If Landlord's mortgagee shall require modifications of the terms and
         provisions of this Lease, Tenant agrees to execute and deliver to
         Landlord the agreements required to affect such Lease modification
         within thirty (30) days after Landlord's request therefor. In no event,
         however, shall Tenant be required to agree to any modification of the
         provision of this Lease relating to: the amount of Rent or other
         charges reserved herein; the size and/or general location of the
         Premises; the duration and/or commencement date of the Lease Term; or
         reducing the improvements to be made by Landlord to the Premises prior
         to the delivery of possession.

29. ESTOPPEL CERTIFICATES.

         Tenant agrees that at any time within ten (10) days following written
         notice from Landlord, it will execute, acknowledge and deliver to
         Landlord or any proposed mortgagee or purchaser a statement in writing
         certifying whether this Lease is in full force and effect and, if it is
         in full force and effect, what modifications have been made to the date
         of the certificates and whether or not any defaults or offsets exist
         with respect to this Lease and, if there are, what they are claimed to
         be and setting forth dates to which Rent or other charges have been
         paid in advance, if any, and stating whether or not Landlord is in
         default, if so, specifying what the default may be. The failure of
         Tenant to execute, acknowledge, and deliver to Landlord a statement as
         above shall constitute an acknowledgment by Tenant that this Lease is
         unmodified and in full force and effect and that the Rent and other
         charges have been duly and fully paid to and including the respective
         due dates immediately preceding the date of Landlord's notice to Tenant
         and shall constitute as to any person, a waiver of any defaults which
         may exist prior to such notice.

30. MISCELLANEOUS.

         (A) In the event that Tenant desires to store or maintain the type or
         character of goods or materials in the Premises which cause an increase
         in insurance premiums, Tenant shall first obtain the written consent of
         Landlord and Tenant shall reimburse Landlord for any increase in
         premiums caused thereby.

         (B) If any term or provision of this Lease is declared invalid or
         unenforceable, the remainder of this Lease shall not be affected by
         such determination and shall continue to be valid and enforceable.

         (C) This agreement contains the entire Lease contract between the
         parties hereto. A short form of this Lease, for the purpose of
         recording, may be executed by the

         parties simultaneously herewith and if either party desires to record
         this Lease, the short form shall be used for that purpose.

         (D) The parties executing this Lease warrant that this agreement is
         being executed with full corporate authority and that the officers
         whose signatures appear hereon are duly authorized and empowered to
         make and execute this Lease in the name of the corporation by
         appropriate and legal resolution of its Board of Directors.

         (E) Unless the context clearly denotes the contrary, the word "Rent" or
         "Rental" as used in this Lease not only includes cash Rental, but also
         all other payments and obligations to pay assumed by the Tenant,
         whether such obligations to pay run to the Landlord or to other
         parties.

         (F) It is mutually agreed by and between Landlord and Tenant that the
         respective parties hereto shall, and they hereby do, waive trial by
         jury in any action, proceeding or counterclaim brought by either of the
         parties hereto against the other on any matter whatsoever arising out
         of or in any way connected with this Lease, the relationship of
         Landlord and Tenant, Tenant's use of or occupancy of the Premises or
         any claim of injury or damage and any emergency statutory or any other
         statutory remedy. If Landlord commences any summary proceeding for
         nonpayment of Rent, Tenant will not interpose any counterclaim of
         whatever nature or description in any such proceeding.

31. DEFAULT RATE OF INTEREST

         All amounts owed by Tenant to Landlord pursuant to any provision of
         this Lease shall bear interest from the date due until paid at eighteen
         percent (18%) per annum, unless a lesser rate shall then be the maximum
         rate permissible by law with respect thereto, in which event said
         lesser rate shall be charged.

32. EXCULPATORY PROVISIONS

         It is expressly understood and agreed by and between the parties
         hereto, anything herein to the contrary notwithstanding, that each and
         all of the representations, warranties, covenants, undertakings and
         agreements herein made on the part of Landlord while in form purporting
         to be the representations, warranties, covenants, undertakings and
         agreements of Landlord are nevertheless each and every one of them made
         and intended, not as personal representations, warranties, covenants,
         undertakings and agreements by Landlord or for the purpose or with the
         intention of binding Landlord personally, but are made and intended for
         the purpose only of subjecting Landlord's interest in the Premises to
         the terms of this Lease and for no other purpose whatsoever, and in
         case of default hereunder by Landlord, Tenant shall look solely to the
         interests of Landlord in the Premises; and that Landlord shall not have
         any personal liability to pay any indebtedness accruing hereunder or to
         perform any covenant, either express or implied, herein contained, all
         such personal liability, if any, being expressly waived and released by
         Tenant and by all persons claiming by, through or under Tenant.

33. MORTGAGE PROTECTION

         Tenant agrees to give any holder of any first mortgage or first trust
         deed in the nature of a mortgage (both hereinafter referred to as a
         "First Mortgage") against the Premises, or any interest therein, by
         registered or certified mail, a copy of any notice or claim of default
         served upon Landlord by Tenant, provided that prior to such notice
         Tenant has been notified in writing (by way of service on Tenant of a
         copy of an assignment of Landlord's interest in leases, or otherwise)
         of the address of such First Mortgage holder. Tenant further agrees
         that if Landlord shall have failed to cure any such default within
         twenty (20) days after such notice to Landlord (or if such default
         cannot be cured or corrected within that time, then such additional
         time as may be necessary if Landlord has commenced within such twenty
