Dear Rich:

      This letter, when accepted by you, shall constitute an amendment to the
employment agreement (the "Agreement") dated January 2, 2001, between Wire One
Technologies, Inc. (the "Company") and you. Capitalized terms not defined herein
shall have the respective meanings ascribed to them under the Agreement. The
Company and you hereby agree as follows:

1.    The first sentence of Paragraph 1 of the Agreement is, effective as of the
      date of this amendment, amended by deleting the phrase "President and"
      therefrom.

2.    Paragraph 2(b) of the Agreement is amended, effective commencing with the
      second calendar quarter of 2002, to read in its entirety as follows:

      "You shall be entitled to receive such cash bonuses as the Company may,
      from time to time and in its sole discretion, determine. You shall, in any
      event, be entitled to receive a cash bonus (the "Formula Bonus") with
      respect to any calendar year of the Employment Period (each a "Year"),
      based upon the performance criteria set forth below, of up to a maximum
      for such Year as follows:

                           Year                      Maximum Formula Bonus
                           ----                      ---------------------
                           2002                             165,000
                           2003                             195,000

      The Formula Bonus for each Year shall be payable in four equal calendar
      quarterly installments; however, the installment with respect to any
      calendar quarter shall be payable only upon satisfaction of the following
      conditions (the "Performance Conditions"): (i) the Company's net revenues
      exclusive of revenues from discontinued operations ("Continuing Revenues")
      for such quarter, as reported in the Company's filings with the Securities
      and Exchange Commission, are greater than the Continuing Revenues for the
      corresponding quarter of the preceding calendar year as so reported and
      (ii) the Company has at least $500,000 of "EBITDA" (that is, earnings
      before interest, taxes, depreciation and amortization, exclusive of
      non-recurring items and otherwise computed on a basis consistent with past
      practice, as the Company publicly discloses that figure) from continuing
      operations during such quarter (it being understood that, if any Formula
      Bonus installment has not been earned by you as a result of the failure of
      either of the Performance Conditions to be satisfied for that quarter,
      such unpaid installment shall be permanently forfeited). All
      determinations of satisfaction of the Performance
<PAGE>

      Condition shall be made by the Compensation Committee of the Board of
      Directors in accordance with the criteria set forth in this subparagraph
      (b).

3.    Except as modified hereby, the Agreement remains in full force and effect.

                                    Yours very truly,

                                    WIRE ONE TECHNOLOGIES, INC.

                                 CORPOREX CENTER
                                MIAMISBURG, OHIO

THIS LEASE AGREEMENT, hereinafter known as the "Lease," entered into effect this
21st day of December, 2001, between Key Property Development Corporation, a
Kentucky corporation, whose principal place of business is 100 East RiverCenter
Blvd., Suite 1100, Covington, Kentucky 41011, hereinafter known as "Landlord,"
and WIRE ONE TECHNOLOGIES, INC., a Delaware corporation, whose principal place
of business is 225 Long Avenue; Hillside, New Jersey 07205, hereinafter known as
"Tenant."

                                   WITNESSETH:

In consideration of the rent hereafter reserved and the covenants herein
contained, each party to this Lease hereby agrees:

(1)   PREMISES:

      Landlord does hereby lease and demise to the Tenant and Tenant does hereby
      take and rent of Landlord, the following Leased Premises:

            Forty-Nine Thousand Two Hundred and Seventy-Seven (49,277) square
            feet of an Eighty-Five Thousand Six Hundred and Twenty-Nine (85,629)
            square foot building located at the intersection of Maue Road, Lyons
            Road and Byers Road in Miamisburg, Montgomery County, Ohio, which
            property is more specifically described in Exhibit "B" attached
            hereto and made a part hereof. That portion which is leased to
            Tenant is designated on the floor plan attached as Exhibit "A" and
            is hereinafter known as the "Leased Premises." The measurements of
            the Leased Premises are based on the dimensions shown on the blue
            print attached to this Lease as Exhibit "E" and the Tenant accepts
            the measurements as shown. The entire building, of which the Leased
            Premises form a part, is hereinafter known as the "Building." The
            Building is situated upon a tract of land hereinafter known as the
            "Developed Parcel," which is more particularly described in Exhibit
            "B."

(2)   PARKING AND LOADING:

      Landlord designates and reserves 120 parking spaces for Tenant's exclusive
      use, which reserved spaces shall be located within the area shown on
      Exhibit "E" and which reserved spaces shall be available at the
      commencement of this Lease. Landlord shall have the obligation to enforce
      Tenant's parking rights and, in furtherance of this obligation, Landlord
      shall install reasonably appropriate signage or other identification
      mutually acceptable to Landlord and Tenant designating the spaces and/or
      areas reserved for Tenant's exclusive use. Landlord shall not be obligated
      to mark or place a sign on each space reserved for Tenant's

                                       1
<PAGE>

      exclusive use. In consideration of this grant, and in recognition of the
      fact that the Building houses two tenants, Tenant understands and agrees
      that Landlord reserves the right to reserve some or all of the parking
      which is not reserved for Tenant's exclusive use, for the exclusive use of
      the other tenant in the Building. Until such time as Landlord delivers
      written notice of any such reservation, Landlord hereby grants to Tenant
      the right to use the off street parking located on the Developed Parcel
      surrounding the Building in a manner conducive to good business practice
      whereby Tenant uses parking spaces at no charge on a non-exclusive basis
      in common with other tenants of the Building. Such parking, in conjunction
      with the visitors parking area, shall be for the use of the Tenant's
      officers, agents, employees, and visitors on a non-reserved basis.

      If the Landlord designates a portion of the parking area for employee
      parking, employees of the Tenant shall use that portion of the parking
      area, thereby leaving the remaining parking spaces in the parking area
      open for visitor in and out traffic.

      The Leased Premises include existing dock doors at the rear of the
      Building and the right to exclusive use of the concrete truck aprons at
      the rear of the Leased Premises, as shown on Exhibit "E".

(3)   TERM:

      The term of this Lease shall be for approximately six (6) years beginning
      on the ___ business day after the date of this Lease (the "Commencement
      Date") and ending on December 31, 2007, subject however to the terms of
      Paragraph 4 and further subject to any of the other conditions or
      covenants of this Lease or pursuant to law.

(4)   CONDITIONS OF AND IMPROVEMENTS TO LEASED PREMISES:

      Immediately upon execution of this Lease, Landlord shall commence the
      alterations or improvements to the Leased Premises indicated on Exhibit
      "C" ("Landlord's Work"). Landlord shall proceed diligently with the
      Landlord's Work and use its best efforts to complete same within five (5)
      business days after the date of this Lease; but, if the Landlord's Work is
      not substantially completed or the Leased Premises be not available for
      occupancy by said date, Tenant shall have no claim against Landlord due to
      such delay, excepting only that the term of this Lease shall not commence
      until the Leased Premises are deemed to be available to Tenant, and the
      term shall expire six (6) years thereafter (plus the number of days until
      the end of the calendar month in which the Lease would otherwise expire);
      and excepting that if the Landlord's Work is not completed by January 15,
      2002, Tenant shall have the right to terminate this Lease by written
      notice to Landlord. The Leased Premises shall be deemed to be available to
      Tenant at the earlier of the time when:

      (a)   the Landlord's Work is substantially completed (notwithstanding that
            Tenant might not have completed installation and/or connection of
            its fixtures and/or equipment) and Landlord has delivered a
            certificate of occupancy for the Leased Premises in its "as is"
            current condition; or

      (b)   the Tenant actually takes possession of the Leased Premises.

                                       2
<PAGE>

      Landlord represents and warrants to Tenant that, effective as of the
      Commencement Date: (i) the Leased Premises shall be clean and the
      plumbing, electrical and mechanical systems in the Leased Premises shall
      be in good operating condition; and (ii) the Leased Premises shall comply
      with all applicable federal, state and local laws and regulations,
      including but not limited to provisions enacted for the protection of the
      environment and the Americans with Disabilities Act. Tenant shall have
      thirty (30) days following the Commencement Date to deliver a punch list
      itemizing defects in the Landlord's Work, and Landlord shall promptly
      correct all such defects. Landlord further represents and warrants that
      all Building systems in the Leased Premises, including but not limited to
      plumbing, electrical, mechanical and heating, ventilating and
      air-conditioning systems serving the Leased Premises shall remain in good
      operating order and condition for a period of eighteen (18) months
      following the Commencement Date, except for damage, repairs or
      replacements incurred or necessitated due to Tenant's failure to maintain
      such equipment and systems in accordance with the terms of this Lease
      Agreement or resulting from Tenant's extraordinary use of the Leased
      Premises. Tenant represents that it shall primarily be operating one shift
      only within the Leased Premises.

      Immediately after the Commencement Date of this Lease has been determined,
      if at variance with Paragraph 3, Landlord and Tenant shall execute a
      written instrument fixing the commencement and termination dates of this
      Lease.

      Tenant's taking of possession shall be conclusive evidence that Leased
      Premises were then in good order and satisfactory condition, except for
      defects in Landlord's Work, if any.

      Notwithstanding anything else to the contrary in this Paragraph 4, if
      Landlord is not able to complete the Landlord's Work due to delays caused
      by Tenant, its employees, agents or contractors, the term of this Lease
      shall not be delayed, but shall commence according to Paragraph 3.

(5)   OCCUPANCY PRIOR TO TERM

      If permitted by law, landlord may allow Tenant to occupy the Leased
      Premises prior to the commencement of the term stated in Paragraph (3). If
      Tenant occupies the Leased Premises on a day other than the first day of
      the month, the Monthly Base Rent provided for in Paragraph (8) and the
      Additional Rent provided for in Paragraph (10) shall be adjusted and
      prorated so the Tenant shall only pay rent for the actual number of days
      in the month. Tenant shall also comply with all other terms and provisions
      of this Lease in the same manner as if the term had, in fact commenced.

(6)   CONTINUANCE OF OCCUPANCY:

      It is further agreed by Landlord and Tenant that Tenant shall physically
      occupy the Leased Premises during the entire original term and renewal
      term, if any, inasmuch as the appearance of continued occupancy of the
      Leased Premises is of utmost importance to the Landlord in the renewal of
      other leases in the Building, in the renting of vacant space to other
      tenants and in the maintenance of the character and quality of the
      Building. Tenant shall be

                                       3
<PAGE>

      construed to have complied with this requirement so long as Tenant
      maintains its furniture in the lobby area of the Leased Premises and keeps
      the Leased Premises lighted during regular business hours. Tenant's
      failure to comply with the requirements of this Section shall constitute
      an event of Non-Monetary Default under the Lease (as defined in Section
      27(b), below).

(7)   SECURITY DEPOSIT:

      Tenant shall deposit with Landlord upon execution hereof the sum of
      Fourteen Thousand Three Hundred Seventy-Two and 46/100 Dollars
      ($14,372.46) 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 this
      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 Landlord 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 previously stated. Said
      Security Deposit shall not earn interest thereon for the benefit of
      Tenant. No trust relationship is created herein between Landlord and
      Tenant with respect to said Security Deposit.

      If and when Tenant has performed all of its obligations hereunder, said
      Security Deposit (or so much thereof as has not been used up and applied
      by Landlord as provided above) shall be returned to Tenant within fifteen
      (15) days after Landlord's receipt of written notice from Tenant
      indicating that Tenant has vacated the Leased Premises and requesting the
      return of the Security Deposit, and after an inspection by Landlord
      establishing that Tenant vacated the Leased Premises in substantially the
      same condition in which it was received by Tenant, ordinary wear and tear
      excepted. The parties shall use their best efforts to conduct this
      inspection within five (5) business days after Tenant vacates the Leased
      Premises. The Security Deposit, which is returned to Tenant, may, at
      Landlord's option, be returned to the last assignee, if any, of Tenant's
      interest hereunder.

(8)   BASE RENT:

      (a)   As annual base rent for the use and occupancy of the Leased Premises
            during the initial term, Tenant shall pay to Landlord rent pursuant
            to the schedule attached as Exhibit "D."

            The annual base rent is to be payable in equal monthly installments,
            ("Monthly Base Rent") in advance on the first day of each and every
            month during the initial or extended term of this Lease, except that
            Tenant shall pay the first installment of Monthly Base Rent upon the
            execution of this Lease.

      (b)   Tenant agrees to pay as supplemental base rent for the use of said
            Leased Premises an amount equal to ten percent (10%) of any Monthly
            Base Rent payment which is not received by Landlord within five (5)
            days of the date said Monthly Base Rent is due;

                                       4
<PAGE>

            except that because this charge is imposed in order to deter
            "frequent" offences, Landlord agrees to waive any such supplemental
            base rent once during each calendar year of the Lease term and any
            renewal terms. Said supplemental base rent shall be in addition to
            any other amounts due under this Lease.

      (c)   If this Lease commences on a day other than the first day of the
            month, the first and last monthly installments of rent provided for
            in Paragraph 8(a) shall be adjusted and pro-rated so that Tenant
            shall only pay rent for the actual number of days in the first and
            last months of said term; but for all other months, Tenant shall pay
            the full monthly installment on the first day of each and every
            month.

      (d)   Rent shall be mailed by Tenant to Landlord at Landlord's principal
            place of business or at such other place as Landlord may designate
            in writing. Rent shall be payable promptly without deduction or
            setoff or prior demand thereof by Landlord. All payments shall be in
            U.S. dollars, in cash or by check, all checks subject to collection.

(9)   ESCALATION OF BASE RENT:

      (a)   At the beginning of and for each Lease Year, as hereinafter defined,
            commencing with the first month of the second Lease Year (i.e.
            January, 2003), the annual base rent (and the corresponding Monthly
            Base Rent as defined in Paragraph 8(a)) shall be adjusted as set
            forth in Exhibit "D."

      (b)   Intentionally Omitted.

      (c)   As used herein, the term "Lease Year" means each calendar year
            during the Lease Term, except that the first Lease Year shall
            include the period of time from the Commencement Date until December
            31, 2001.

(10)  ADDITIONAL RENT:

      In addition to the amounts imposed in Paragraphs 8 and 9, Tenant agrees to
      pay as additional rent for each month during the term of this Lease, the
      amounts required by Paragraphs 11, 12 and 13.

(11)  MAINTENANCE OF COMMON AREAS; OTHER SERVICES; AND UTILITIES:

      (a)   Landlord shall arrange to keep the exterior parking lot, driveways,
            and sidewalks in good condition and repair consistent with standards
            for Class A level buildings of similar type in the Montgomery County
            area, clean and free from snow, ice, rubbish and other obstructions;
            provide water; arrange periodically for grass cutting, landscaping
            and yard maintenance; and arrange for illumination of the parking
            lot, grounds, and common exterior Building signs serving the
            Developed Parcel. Landlord shall also pay property management fees,
            licenses, permits, inspection fees, and the cost of all labor,
            contracted labor, materials and other services paid or incurred by
            Landlord in the operation and maintenance of the Building and

                                       5
<PAGE>

            Developed Parcel. Landlord shall also provide the following services
            to the Building and the Leased Premises, subject, however, to the
            provisions of Subsection 11(d) below herein, consistent with
            standards for Class A level buildings of similar type in the
            Montgomery County area: (i) heating, ventilation and air
            conditioning service as necessary to maintain comfortable
            temperatures in the Leased Premises during regular business hours
            (subject to the provisions of 11(d)); (ii) electric service to the
            Leased Premises, including the average minimum number of watts per
            square foot necessary to support ordinary office use; and (iii) hot
            and cold running water for lavatory and drinking purposes.

      (b)   For each Lease Year Tenant shall reimburse Landlord for (57.55%)
            (hereafter, its "Pro Rata Share") of the actual but reasonable cost
            of the services enumerated in Paragraph 11(a) (the "Operating
            Expenses"). The Operating Expenses shall not exceed fair market
            rates customarily charged in the Montgomery County area between
            independent parties contracting for Class A quality services, and no
            capital expenditures shall be included in the Operating Expenses.
            The amount of Tenant's estimated payment of Tenant's Pro Rata Share
            of Operating Expenses (including taxes and insurance) during the
            first Lease Year (i.e. from the Commencement Date through December
            31, 2002) is $3,647.04 per month (the "Estimated Pro Rata Share").
            At least fifteen (15) days before the beginning of each Lease Year,
            Landlord shall give Tenant written notice of the amount of Tenant's
            Estimated Pro Rata Share for the following Lease Year and Tenant
            shall pay 1/12 of this amount for each calendar month, in addition
            to the Monthly Base Rent set out in Exhibit D.

      (c)   On or before April 30 of each year, Landlord shall deliver to Tenant
            a statement showing the actual amount, on a line-item basis, which
            Landlord has expended for the Operating Expenses and Tenant's
            proportionate share thereof (the "Landlord's Statement"). Within
            thirty (30) days after the delivery by Landlord to Tenant of such
            Landlord's Statement, Tenant shall pay to Landlord the amount by
            which Tenant's Pro Rata Share of the actual Operating Expenses
            exceeds the amount Tenant has paid as Tenant's Estimated Pro Rata
            Share during the previous Lease Year. In the event that in any year
            Tenant has advanced to Landlord sums in excess of Tenant's Pro Rata
            Share, Landlord shall credit Tenant the amount by which the
            Estimated Pro Rata Share exceeded the Tenant's Pro Rata Share of the
            actual Operating Expenses, or if the credit would be payable after
            the termination of this Lease, Landlord shall refund the amount of
            such overpayment to Tenant within thirty (30) days.

            Notwithstanding the foregoing, Tenant shall have six (6) months
            after the receipt of any Landlord's Statement to notify Landlord in
            writing of a dispute as to specific items and/or amounts charged to
            Tenant thereunder. Upon Tenant's giving of forty-five (45) days
            written notice to Landlord at any time thereafter, Tenant, at its
            expense, may examine Landlord's books and records relating to the
            operation of the Building and any other amounts for which Tenant
            pays a Pro Rata Share (such as taxes and insurance) and the items in
            dispute to determine the accuracy of the Landlord's Statement.
            Landlord shall make all these records available to Tenant or its
            agents at Landlord's offices during regular business hours following
            reasonable

                                       6
<PAGE>

            advance written notice. If the audit discloses that Landlord's
            Statement resulted in an overcharge to Tenant greater than: (a) five
            percent (5%) of the total Operating Expenses (excluding taxes); or
            (b) one percent (1%) of the amount charged for real estate taxes;
            then Landlord shall pay Tenant's actual but reasonable costs and
            expenses in connection with the audit up to a maximum of Two
            Thousand Five Hundred ($2,500.00) Dollars. If there is no such
            overcharge, of if any such overcharge is less than five (5%)
            percent, then Tenant shall reimburse Landlord for Landlord's actual
            but reasonable costs and expenses associated with the audit, up to a
            maximum of Two Thousand Five Hundred Dollars ($2,500.00). In any
            case (whether the audit shows an overcharge or an undercharge),
            Tenant's Pro Rata Share of the Operating Expenses shall be adjusted
            to correspond with the figures determined in the audit.

            All computations described in Sections 11(a) through 11(c) shall be
            made on the basis of a calendar year, except that computations for
            the year 2001 shall be made on the basis of the actual number of
            days between the Commencement Date and December 31, 2001. If the
            Lease terminates before the end of any calendar year, computations
            shall be made on the basis of the proportion between the number of
            days that this Lease was in effect during that year and 365.

      (d)   Tenant shall pay for all utilities consumed in the Leased Premises.
            Landlord, at Tenant's expense, shall install separate meters for
            natural gas (if available) and electricity. Notwithstanding
            Subparagraph 11(a), Landlord reserves the right to install a water
            meter, at Tenant's expense, for the purpose of separately charging
            Tenant for water used in the Leased Premises. Tenant shall also
            obtain and pay for janitorial and cleaning services in the Leased
            Premises and for all trash and garbage removal services, including
            the costs and expenses of providing dumpsters and other required
            trash receptacles.

(12)  TAXES AND ASSESSMENTS:

      For each calendar year, Tenant shall reimburse Landlord for its Pro Rata
      Share of all real estate taxes and assessments levied or charged against
      the Building and the Developed Parcel. In the event Tenant has advanced to
      Landlord sums in excess of Tenant's Pro Rata Share, Landlord shall rebate
      Tenant for the difference. In the event Tenant has advanced to Landlord
      less than Tenant's Pro Rata Share, Tenant shall pay to Landlord, upon
      receipt of an invoice, the difference between the Tenant's advances for
      the calendar year and the amount of Tenant's Pro Rata Share.

      All personal property taxes charged or levied against Tenant's furniture,
      fixtures and equipment in the Leased Premises shall be paid by Tenant.

(13)  INSURANCE:

      (a)   Landlord shall keep the Building insured against loss by fire or
            other casualty with extended coverage in an amount determined by the
            Landlord, and said policies shall include a standard waiver of
            subrogation clause against Tenant.

                                       7
<PAGE>

            In the event the cost of premiums on Landlord's fire and extended
            insurance increases due to the hazardous nature of the use and
            occupancy by Tenant of the Leased Premises, then the entire increase
            in insurance cost shall be paid by Tenant in a lump sum upon receipt
            of invoice from the Landlord.

      (b)   Landlord shall at all times maintain public liability insurance for
            the common areas and the exterior of the Building as well as the
            sidewalks and the parking lot of the Developed Parcel, and said
            policies shall include a standard waiver of subrogation clause
            against Tenant.

      (c)   For each calendar year, Tenant shall reimburse Landlord for its Pro
            Rata Share of Landlord's insurance premiums. In the event Tenant has
            advanced to Landlord sums in excess of Tenant's Pro Rata Share,
            Landlord shall rebate Tenant for the difference. In the event Tenant
            has advanced to Landlord less than Tenant's Pro Rata Share, Tenant
            shall pay to Landlord, upon receipt of an invoice, the difference
            between the Tenant's advances for the calendar year and the amount
            of Tenant's Pro Rata Share.

      (d)   The Tenant covenants and agrees that it will, at all times during
            the term hereof, at its own expense, carry and keep in full force
            and effect in companies satisfactory to Landlord, public liability
            insurance in form satisfactory to Landlord, with limits of (a) at
            least ONE MILLION DOLLARS ($1,000,000.00) for injury, including
            death, to any one person, and (b) at least ONE MILLION DOLLARS
            ($1,000,000.00) for injury, including death in any one casualty, and
            (c) at least ONE MILLION DOLLARS ($1,000,000.00) for property damage
            coverage. Landlord may increase the above limits to such greater
            amounts of insurance coverage as Landlord may from time to time
            reasonably require, based on: (i) Landlord's loss experience, or
            (ii) insurance coverages required on similar class A buildings of
            similar type within Montgomery County, Ohio, or, (ii) as may be
            required by Landlord's lenders, but not more often than annually and
            in no case shall Tenant be required to carry insurance in excess of
            $10,000,000. Tenant may comply with these requirements by furnishing
            blanket policies of insurance which list Landlord and the Leased
            Premises as a named insured. Tenant shall also, at its own expense,
            carry plate glass insurance on the Leased Premises. All such
            policies shall name the Landlord and the Tenant as parties insured,
            and shall contain a provision that the same may not be canceled or
            changed without giving to the Landlord at least thirty (30) days
            written notice prior to expiration or cancellation of any such
            policy. Tenant shall furnish to Landlord a certificate of insurance
            with respect to each policy and, within ten (10) days after receipt
            of Landlord's written request, Tenant shall deliver a certified copy
            of the insurance policy.

      (e)   All property in the Leased Premises, in the Building or on the
            Developed Parcel, belonging to Tenant, its agents, employees or
            invitees or to any other person, shall be there at the risk of
            Tenant or such other person only, and Landlord shall not be liable
            for damage thereto or theft, misappropriation, or loss thereof. In
            furtherance of this provision, Tenant shall at all times and at its
            expense maintain insurance against loss by fire or other casualty
            with extended coverage on its furniture, fixtures, inventory,

                                       8
<PAGE>

            equipment, supplies and personal property, in an amount determined
            by Tenant; said policies shall include a standard waiver of
            subrogation clause against Landlord.

      (f)   Landlord, its agents and employees shall not be liable for injury to
            person or damage to property sustained by Tenant, by any occupant of
            the Leased Premises, the Building or the Developed Parcel, or by any
            other person, occurring or resulting directly or indirectly from any
            existing or future condition, defect, matter, or thing in the Leased
            Premises, in the Building or on the Developed Parcel or from
            equipment or appurtenances therein or from accident or from any
            occurrence, act, or from negligence or omission of any Tenant,
            occupant or any other person; but nothing in this Subparagraph (f)
            shall be deemed to relieve Landlord from liability for damages for
            property damage or bodily injuries or death to any person caused by
            or resulting from the gross negligence or willful misconduct of
            Landlord, its agents or employees, or from Landlord's breach of its
            obligations under this Lease.

(14)  FIRE OR OTHER CASUALTY

      Should the Leased Premises be damaged or destroyed by any cause and such
      damage or destruction be of such a nature that it may be repaired or
      restored within a period of one hundred twenty (120) days after the
      occurrence, then this Lease shall not terminate, but it shall be the
      obligation of Landlord to repair or restore the Leased Premises as nearly
      as possible to its condition prior to such damage or destruction, and the
      Landlord shall proceed promptly to make such repairs or restoration;
      provided, however, that such repairs or restoration can be made by
      Landlord for an amount not in excess of the amount recovered by Landlord
      on the fire and extended insurance. There shall be an equitable abatement
      of rent during the period that the Leased Premises may be wholly or
      partially unavailable for use by Tenant for the operation of its business.

      If Landlord determines that the damage or destruction is of a character
      that will not permit repair or restoration of the Leased Premises within
      the one hundred twenty (120) days after the occurrence thereof, or if the
      cost of such repair or restoration exceeds Landlord's insurance recovery
      and Landlord elects not to pay the difference between the insurance
      recovery and the actual cost of the restoration, then Landlord shall
      promptly deliver written notice of this fact to Tenant, in which case
      either Landlord or Tenant shall have the privilege of canceling the
      unexpired term of this Lease upon giving written notice to the other
      within ten (10) business days after the date the notice is delivered to
      Tenant. If the damage or destruction occurs during the last six months of
      the Lease term, or if Landlord fails to complete the restoration following
      any damage or destruction within the one hundred twenty (120) day period
      after the occurrence of the damage or destruction, Tenant shall have the
      right to terminate the Lease by written notice delivered on or before the
      130th day after the casualty.

(15)  USE OF LEASED PREMISES:

      (a)   Tenant shall use and occupy the Leased Premises for general office
            and warehouse use (including but not limited to shipping, receiving
            and distribution activities) and for no other purpose.

                                       9
<PAGE>

      (b)   Landlord covenants and agrees that the Leased Premises, in its state
            existing on the date that the Lease term commences, but without
            regard to the use of which Tenant will use the Leased Premises, does
            not violate and will not, as of the Commencement Date, violate any
            covenant or restrictions of record, or any applicable building code,
            regulation or ordinance in effect on such Lease term Commencement
            Date, including all provisions enacted for the protection of the
            environment, the Americans with Disabilities Act and all
            requirements of the Landlord's insurance carrier.

      (c)   The Tenant hereby covenants and agrees as follows:

            (i)   To comply, from and after the commencement date, with all
                  Federal, State, County and City laws, building codes,
                  ordinances, rules and regulations affecting the use or
                  occupancy of the Leased Premises ("Applicable Laws").
                  Notwithstanding the foregoing, Tenant shall not be required to
                  correct violations of Applicable Laws existing on the
                  Commencement Date or to comply with requirements of any future
                  violations of Applicable Laws unless such compliance is
                  legally required solely because of the unique nature of
                  Tenant's use and occupancy of the Leased Premises (not common
                  to general office and warehouse operations, including
                  shipping, receiving, and distribution) or because of
                  alterations constructed by Tenant in the Leased Premises.

            (ii)  Not to use the Leased Premises for any disorderly or unlawful
                  purpose or use inconsistent with applicable zoning;

            (iii) To obtain from appropriate governmental agencies at the
                  Tenant's expense any and all permits, licenses, and the like,
                  required to permit Tenant to occupy the Leased Premises
                  (except the certificate of occupancy, which shall be furnished
                  by Landlord) and to be at all times in compliance with such
                  permits, licenses, and the like, and all applicable
                  governmental ordinances and regulations;

            (iv)  To keep the Leased Premises clean and free from rubbish and to
                  keep the windows and signs neat, clean, and in good order, all
                  at Tenant's sole expense; or, if Tenant fails to perform these
                  obligations within thirty (30) days after written notice from
                  Landlord, then Landlord, at its sole discretion, shall have
                  the right to perform these maintenance items and Tenant agrees
                  to reimburse Landlord for its actual, but reasonable costs;

            (v)   Not to store any material, trash or refuse of any nature
                  whatever within the Leased Premises or on the exterior of the
                  Leased Premises or Developed Parcel (except in dumpsters or
                  other trash receptacles approved by Landlord) nor to erect any
                  screen or fence without the prior written consent of Landlord;

            (vi)  To refrain from keeping gasoline, other inflammable material,
                  any explosives or any other hazardous material within the
                  Leased Premises or on the Developed Parcel, or from doing any
                  act or thing which may make void or voidable the Landlord's

                                       10
<PAGE>

                  insurance against fire, and to conform to all rules or
                  regulations from time to time established by the appropriate
                  insurance rating organization;

            (vii) To comply with all the Rules and Regulations which have been
                  adopted by Landlord, attached as Exhibit "F," (or which may be
                  hereafter adopted by Landlord and delivered to Tenant) for the
                  protection and welfare of the Building, the Developed Parcel
                  and other tenants; so long as the revisions do not impose
                  material or substantial additional burdens upon Tenant and all
                  such rules and regulations are uniformly enforced against all
                  tenants of the Developed Parcel.

(16)  REPAIRS:

      (a)   Tenant Repairs

            Tenant agrees that during the full term of this Lease or any renewal
            thereof, it will, at its own expense, keep the interior of the
            Leased Premises in good condition and shall not let the Leased
            Premises and equipment, fall out of repair, and that it will
            maintain the Leased Premises and equipment, and make repairs
            promptly as they become necessary. At commencement of this Lease,
            Landlord shall supply the Leased Premises with the required lamps,
            bulbs, ballasts, and starters, but replacements thereof shall be at
            Tenant's expense.

            Interior maintenance shall be deemed to include, but shall not be
            limited to, repairs or replacements required for windows, doors,
            floors, interior walls, ceilings, painting and decorating, and
            repairs to heating, air conditioning, plumbing and electrical
            fixtures, and equipment. Tenant shall change the filters in the
            ventilation system on regular intervals. Notwithstanding, any other
            provisions of this Subparagraph 16(a), Tenant shall not be obliged
            to: (i) make such repairs as are necessitated by fire or other
            perils provided for by extended coverage clauses (whether or not
            caused by the active or passive negligence of the Tenant) for which
            damage or loss insurance is carried by the Landlord; or (ii) pay
            more than $1,500 toward the cost of any single replacement, except
            for damages caused by Tenant's negligence or willful misconduct, for
            which Tenant shall pay the entire cost.

            Landlord covenants and agrees that all equipment on the Leased
            Premises shall be in good working order on the Commencement Date and
            for a period of eighteen (18) months thereafter, except for damage,
            repairs, or replacements incurred or necessitated due to Tenant's
            failure to maintain such equipment and systems in accordance with
            the terms of this Lease Agreement or resulting from Tenant's
            extraordinary use of the Leased Premises. Tenant shall at all times
            after the commencement of Tenant's business operations at the
            Demised Premises maintain, at Tenant's sole cost and expense, a
            service contract with a reputable heating, ventilating and air
            conditioning service and repair firm approved by Landlord for the
            provision of such service and repairs to the Demised Premises, which
            shall provide that such contract may not be canceled, materially
            changed or not renewed without at least thirty (30) days advance
            written notice to Landlord at the address and in the manner set
            forth in Section 25 hereof. A copy of such contract shall be

            with Landlord by Tenant promptly upon commencement of Tenant's
            obligation to procure same, and a copy of each replacement thereof
            shall be deposited with Landlord promptly upon Tenant's execution of
            same.

      (b)   Landlord Repairs

            Landlord shall make all repairs necessary to comply with the
            warranties given in Section 4(b) and 16(a) of this Lease. In
            addition, Landlord agrees that during the full term of this Lease,
            it will, at its own expense, keep the exterior structural parts, the
            roof and the foundation of the Building in good condition and repair
            and that it will make such repairs promptly as they become
            necessary, except that Landlord shall not be required to repair
            damages caused by Tenant's negligence or willful misconduct.
            Exterior repairs shall be deemed to include exterior walls, roof,
            gutters, downspouts, plumbing outside the Building and all paved and
            landscaped areas. In addition, Landlord shall pay the excess amount
            of any replacement which costs more than $1,500. Landlord shall make
            such interior repairs and replacements as are necessitated by fire
            or perils provided for by extended coverage clauses (whether or not
            caused by the active or passive negligence of the Tenant) for which
            damage or loss insurance is carried by the Landlord and for which
            insurance proceeds are recovered, including interior decorating
            caused by such fire or other perils. Landlord shall maintain the
            common areas of the Developed Parcel, including the exterior
            utilities and parking areas in good condition and repair throughout
            the Lease term.

(17)  ALTERATIONS:

      No alterations, modifications, additions or installations to the Leased
      Premises shall be made unless the Landlord shall first have given written
      approval of the plans and specifications thereof, and shall have been
      protected, to the Landlord's satisfaction, against any cost or damage
      incident thereto. Prior to any approved construction, Tenant shall first
      have secured all necessary building and other permits. Tenant agrees to
      make such alterations, modifications, additions or installations to the
      Leased Premises as may be required by building, OSHA, or other applicable
      regulations or local codes in the jurisdiction in which the Leased
      Premises are located. All such alterations, modifications, additions, or
      installations, when made, shall become, unless the Landlord elects
      otherwise as provided in Paragraph 17 hereof, the property of the Landlord
      and shall remain upon and be surrendered with said Leased Premises as a
      part thereof at the end of the term of this Lease.

(18)  FIXTURES AND UNAUTHORIZED USE OF PREMISES:

      Tenant shall not without Landlord's prior written consent attach any
      fixtures in or to the Leased Premises or change, alter, or make additions
      to the Leased Premises nor permit any annoying sound device, install any
      additional locks, overload any floor, or deface the Leased Premises. Any
      attached fixtures or any alterations, additions, or improvements made or
      attached by Tenant shall on the expiration or termination of this Lease,
      if requested by Landlord, be promptly removed at Tenant's expense, and the
      Leased Premises restored by Tenant at its expense to its original
      condition, ordinary wear and tear excepted. Any such fixture, alteration,
      addition and/or improvement not requested to be moved shall remain on

                                       12
<PAGE>

      the Leased Premises and shall become and remain the property of Landlord.
      All Tenant's fixtures, installations, and personal property not removed
      from the Leased Premises upon expiration or termination and not required
      by Landlord to have been removed as provided in this paragraph shall be
      conclusively presumed to have been abandoned by Tenant, and title thereto
      shall pass to Landlord under this Lease as by a bill of sale.

(19)  WINDOW COVERINGS AND SIGNAGE:

      Landlord shall, at Tenant's expense, install signage identifying Tenant's
      occupancy. Signage shall meet Landlord's standard specification for Tenant
      signage, in order to provide harmony of the Building as to the exterior
      and interior appearances and also for safety and fire hazard purposes.

      Tenant shall not install signs in the windows of the Leased Premises or
      any other part of the Building or Developed Parcel without first securing
      Landlord's written consent. Any such signage permitted shall meet
      Landlord's standard specification for Tenant signage. Any signs installed
      by Tenant with Landlord's permission shall be removed by Tenant at the
      expiration of this Lease, at its expense, and the Leased Premises shall be
      restored by Tenant.

(20)  INTERRUPTION OF SERVICE:

      Landlord does not warrant that any services to be provided by Landlord
      will be free from interruption due to causes beyond Landlord's reasonable
      control. Temporary interruption of services or unavoidable delay in the
      making of repairs shall not be deemed an eviction or disturbance of
      Tenant's use and possession nor render Landlord liable to Tenant for
      damage by abatement of rent or otherwise nor relieve Tenant from
      performance of its obligations under this Lease. However, if utilities
      and/or other building services necessary to the customary operation of
      Tenant's business at the Leased Premises ("Essential Services") are
      interrupted or stopped as the result of damage or other factors relating
      to the portion of the service or utility line running from the "main line"
      located in the street right-of-way or adjoining the street right-of-way to
      the exterior wall of the Building ("Exterior Cause"), then Landlord shall
      use commercially reasonable efforts to assure that the Essential Services
      are promptly restored. If the Essential Services interrupted as the result
      of any Exterior Cause are not restored within five (5) business days, then
      Tenant's obligation to pay Rent shall abate on a per diem basis from the
      6th business day until the date that Essential Services are restored, and
      if the Essential Services interrupted as the result of any Exterior Cause
      are not restored within sixty (60) business days, then Tenant shall have
      the right to terminate this Lease (unless the interruption or stoppage is
      the result of Tenant's negligence or willful misconduct, in which case
      Tenant's obligation to pay Rent shall not abate and Tenant shall not have
      the right to terminate the Lease). If Essential Services are interrupted
      or stopped for any other reason and service is not restored within 120
      days, then Tenant shall have the right to terminate this Lease by written
      notice to Landlord.

(21)  INDEMNIFICATION:

      Tenant shall pay all loss or damage occasioned by or growing out of the
      use and occupancy of the Leased Premises by Tenant, its agents, employees
      and contractors, and Tenant will

                                       13
<PAGE>

      indemnify, protect, and save Landlord harmless from and against any loss
      or liability thereby or therefore and from and against any expense, cost,
      and attorney fees incurred in connection with any such claim; except that
      Tenant shall not be required to indemnify Landlord for any costs,
      expenses, damages or other losses to the extent that they arise out of:
      (a) the negligence or willful misconduct or strict or statutory liability
      of Landlord or its employees, agents and contractors; (b) Landlord's
      failure to perform its obligations under this Lease; or (c) any defect or
      deficiency in the Building or the Leased Premises which was not created by
      Tenant's use of the Leased Premises or by improvements installed by Tenant
      or its employees, agents and contractors. Landlord shall indemnify, defend
      and hold Tenant, its agents, employees and contractors harmless from all
      claims, suits, losses, damages, fines, penalties, liabilities and expenses
      (including attorneys' fees) resulting from any actual or alleged injury
      (including death) of any person or from any actual or alleged loss of or
      damage to any property arising out of or in connection with the occupancy
      and use of the common areas in the Building and on the Developed Parcel,
      except to the extent that they arise out of the negligence or willful
      misconduct of Tenant or its employees, agents or contractors.

(22)  WARRANTY OF QUIET ENJOYMENT:

      Tenant, upon paying the rents and keeping and performing the covenants of
      this Lease to be performed by Tenant, shall peacefully and quietly hold,
      occupy, and enjoy said Leased Premises during said term or any renewal
      thereof.

(23)  ASSIGNMENT AND SUBLETTING:

      Tenant shall not assign, mortgage or encumber this Lease nor sublet or
      permit the Leased Premises or any part thereof to be used by others,
      without the prior written consent of Landlord in each instance, which
      Landlord shall not unreasonably withhold, condition or delay. The consent
      by Landlord to an assignment or subletting shall not be construed to
      relieve Tenant from obtaining the consent of the Landlord to any further
      assignment or subletting. The consent by Landlord will not be given
      unless: (a) the subtenant or assignee assumes the Tenant's obligations
      under this Lease; and (b) Tenant remains liable for all its obligations
      under this Lease, including extensions or renewals provided for herein.
      Nor will consent be given if Tenant is in default under this Lease. Tenant
      shall notify Landlord of the name of each proposed assignee or subtenant
      and shall provide information to Landlord pursuant to the financial
      standing of the proposed assignee or subtenant.

      Despite the foregoing, Tenant shall have the absolute right without the
      consent of Landlord, but upon notice to Landlord, to assign all of its
      rights under the Lease or sublet all or a portion of the Leased Premises
      to any (i) parent or subsidiary, including the parent of a parent or the
      subsidiary of a subsidiary; (ii) successor by merger; (iii) any person or
      entity who acquires all or substantially all of the Tenant's assets or a
      majority of the ownership interests or shares in tenants; or (iv) any
      person or entity controlled by, under common control with or controlling
      Tenant (each being an "Affiliate"), provided that Tenant shall remain
      liable for the full performance of all obligations of Tenant under this
      Lease and provided further that Tenant is not, at the time of such
      assignment, in default under this Lease.

                                       14
<PAGE>

      No permitted assignment or sublease on the part of Tenant pursuant to this
      paragraph shall trigger any right of Landlord to terminate this Lease.

      In no event shall any proposed subtenant or assignee (other than an
      Affiliate) be an existing tenant of the Building or its subtenant or
      assignee. In no event shall the proposed subtenant or assignee be a person
      or entity with whom Landlord or its agent is negotiating and to or from
      whom Landlord, or its agent, has given or received any written or oral
      proposal within the past one hundred twenty (120) days regarding a lease
      of space in the Building.

      Landlord reserves the right to require as additional rent, fifty percent
      (50%) of any subtenant or assignee rent which is in excess of the base
      rent and additional rent then being paid by Tenant pursuant to this Lease
      (but only after Tenant has recovered the full amount of all expenses of
      obtaining the assignment or sublease, including but not limited to
      commissions, attorneys' fees and alteration costs), and any other profit
      or gain realized by Tenant from such assignment or subletting. All sums
      payable hereunder by Tenant shall be paid as additional rent upon receipt
      by Tenant or upon request by Landlord.

(24)  EMINENT DOMAIN:

      Tenant agrees that if the Leased Premises, or any part thereof (including
      the exclusive parking spaces or access to the parking area), shall be
      taken or condemned for public or quasi-public use or purpose by any
      competent authority, Tenant shall have no claim against Landlord and shall
      not have any claim or right to any portion of the amount that may be
      awarded as damages or paid as a result of any such condemnation, whether
      such amount be awarded for diminution in value to the leasehold or to the
      fee. It is agreed that the full amount of such award, if any, made by the
      taking authorities shall be paid to and retained by Landlord, free of any
      claim by Tenant to any portion thereof, and all rights of Tenant to
      damages therefor, if any, are hereby assigned by Tenant to Landlord. In
      the event that all or substantially all of the Leased Premises shall be
      taken or condemned by any governmental authority, then the term of this
      Lease shall cease and terminate from the date on which the Tenant is
      required, by such taking authority, to surrender possession of said Leased
      Premises and the Tenant shall not have nor make any claim against Landlord
      for the value of any unexpired term of this Lease. In the event that a
      portion of the Leased Premises shall be taken or condemned by any
      governmental authority, then this Lease shall continue in full force and
      effect, and rent shall abate in an amount which bears the same ratio to
      the annual base rent as the value of the floor space taken bears to the
      value of the total floor space of the Leased Premises. All rentals and
      other sums payable by Tenant hereunder shall be adjusted to the date on
      which Tenant is required, by the taking authority, to surrender possession
      of the Leased Premises or portion of the Leased Premises so taken.

(26)  REDELIVERY OF PREMISES

      Tenant shall, on the expiration of this Lease, deliver up the Leased
      Premises in as good order and condition as it now is or may be put by
      Landlord, reasonable use and ordinary wear and tear thereof and damage by
      fire or other unavoidable casualty, condemnation or appropriation
      excepted. Tenant shall promptly surrender all keys to the Leased Premises
      to Landlord.

(27)  DEFAULT: REMEDIES UPON DEFAULT:

      (a)   It shall be an event of default under this Lease if any voluntary or
            involuntary petition in bankruptcy shall be filed by or against
            Tenant, or any voluntary or involuntary proceeding in any court
            shall be instituted to declare Tenant insolvent or unable to pay
            Tenant's debts, or Tenant makes an assignment for the benefit of its
            creditors, or a trustee or receiver is appointed for Tenant or for
            the major part of Tenant's property; except that in the case of any
            involuntary proceedings, so long as Tenant is not in default for
            payment of rent, and continues to pay its rent on a current basis
            thereafter, Tenant shall have sixty (60) days to obtain an order
            dismissing the proceedings.

      (b)   It shall be an event of default under this Lease (a "Monetary
            Default") if: (i) Tenant fails to pay rent when due; or (ii) there
            is any lapse in the insurance which Tenant is required to carry
            under this Lease; or (iii) Tenant takes any action or causes any
            situation which creates an immediate hazard to the health, safety
            and security of persons or property at the Leased Premises or to the
            safe use and operation of the Building; and such nonpayment, lapse
            or failure shall continue for five days after

                                       17
<PAGE>

            Landlord's notice to Tenant. It shall be an event of default under
            this Lease (a "Non-Monetary Default") if Tenant fails to perform or
            observe any other provisions of this Lease and such failure shall
            continue for thirty (30) days after notice thereof shall have been
            given to Tenant; except that no event of default shall occur if
            Tenant commences a cure of such Non-Monetary Default within this
            thirty (30) day period and diligently and continuously pursues the
            cure thereafter.

      (c)   Following any event of default under this Lease, Landlord shall have
            the right to terminate this Lease. Following any Monetary Default
            under this Lease, Landlord shall also have the option to terminate
            Tenant's right to possession without terminating the Lease or to
            terminate this Lease. In either case, Tenant shall surrender
            possession and vacate the Leased Premises immediately, and Landlord
            may enter the Leased Premises in such event with or without process
            of law and retake possession of the Leased Premises and may expel or
            remove the Tenant and any others who may be occupying or within the
            Leased Premises and remove all property therefrom without
            relinquishing any other right given to the Landlord hereunder or by
            operation of law.

      (d)   If a Monetary Default occurs and the Landlord elects to terminate
            the Tenant's right to possession only without terminating this
            Lease, the Landlord may, at its option, enter into the Leased
            Premises, remove the Tenant's signs and other evidences of tenancy,
            and take and hold possession thereof as provided in Subparagraph (c)
            without such entry terminating this Lease or releasing the Tenant
            from the Tenant's obligation to pay the rent for the full term, and
            in any such case, the Tenant shall pay forthwith to the Landlord a
            sum equal to the present value of the entire amount of the rent
            specified in Paragraphs 8, 9 and 10 of this Lease for the residue of
            the stated term plus any other sums then due hereunder. Upon and
            after entry into possession without termination of this Lease, the
            Landlord shall use commercially reasonable efforts to relet the
            Leased Premises or any part thereof for the account of the Tenant
            for such rent, for such time and upon such terms as the Landlord in
            its sole discretion shall determine. Landlord shall not be required
            to accept any tenant offered by the Tenant or to observe any
            instructions given by the Tenant about such reletting, but Landlord
            agrees to work with Tenant in a commercially reasonable manner to
            mitigate damages. In any such case, the Landlord may make repairs,
            alterations, and additions in or to the Leased Premises and
            redecorate the same to the extent deemed by the Landlord necessary
            or desirable, and the Tenant shall, upon demand, pay the cost
            thereof together with the Landlord's expenses of the reletting. If
            the consideration collected for the remaining term of this Lease by
            the Landlord upon any such reletting for the Tenant's account is not
            sufficient to pay the full amount of unpaid rent reserved in this
            Lease together with cost of repairs, alterations, additions,
            redecorating and the Landlord's expenses, costs, fees, and
            commissions the Tenant shall pay to the Landlord the amount of each
            deficiency upon demand. If the consideration collected for the
            remaining term of this Lease from any such reletting, after
            deducting therefrom the cost of repairs, alterations, additions,
            redecorating and the Landlord's expenses, costs, fees, and
            commissions, is in excess of the full amount of the rent reserved
            herein, the Landlord at the end of the stated term of this Lease
            shall account for the surplus thereof to Tenant. Notwithstanding the
            foregoing, so

                                       18
<PAGE>

            long as Landlord has not entered into good faith negotiations with a
            replacement Tenant, Tenant shall have the right to cure any Monetary
            Default, whereupon Tenant's right to possession shall be
            automatically restored and the Lease reinstated.

      (e)   Any property which may be removed from the Leased Premises by the
            Landlord pursuant to the authority of this Lease or of law to which
            the Tenant is or may be entitled may be handled, removed, or stored
            in a commercial warehouse or otherwise by the Landlord at the risk,
            cost, and expense of the Tenant. Landlord shall in no event be
            responsible for the value, preservation, or safekeeping thereof. The
            Tenant shall pay to the Landlord, upon demand, all expenses incurred
            in such removal and all storage charges against such property. Any
            such property of Tenant not removed from the Leased Premises or
            retaken from storage by Tenant within thirty (30) days after the end
            of the term of this Lease, however terminated, shall be conclusively
            deemed to have been forever abandoned by Tenant.

      (f)   If Tenant violates any of the terms and provisions of this Lease or
            defaults in any of its obligations hereunder other than the payment
            of rent or other sums payable hereunder, such violation may be
            restrained or such obligation enforced by injunction.

      (g)   All rights and remedies of Landlord herein enumerated shall be
            cumulative and none shall exclude any other right or remedy allowed
            by law.

      (h)   Any costs and expenses incurred by Landlord (including, without
            limitation, reasonable attorney's fees) in enforcing any of its
            rights or remedies under this Lease shall be deemed to be Additional
            Rental and shall be repaid to Landlord by Tenant upon demand.

      Landlord shall punctually perform all the obligations imposed upon
      Landlord under this Lease. If Landlord fails to perform any such
      obligation within thirty (30) days after written notice from Tenant
      specifically describing the nature of Landlord's failure to perform (a
      "Landlord Default") (except that it shall not be a Landlords' Default if
      the work to be performed by Landlord cannot be completed within thirty
      days of such notice, and Landlord has commenced such work and diligently
      and continuously pursues the cure or completion of such obligation), then
      Tenant shall have the right to perform the obligations described in the
      notice and set-off the actual and reasonable cost of the performance
      against amounts due to Landlord under this Lease. The Landlord Default
      shall be deemed to have been cured when Tenant's expense has been
      reimbursed in full (whether through payment, set-off or otherwise). The
      rights afforded to Tenant under this paragraph shall be construed to be
      cumulative, and not exclusive of any other lawful right or remedy that
      Tenant may have.

(28)  HOLDING OVER:

      So long as Landlord and Tenant are engaged in good faith negotiations for
      the execution of a new lease or an extension of this Lease, Tenant may
      hold over on the same terms and conditions of this Lease for up to two (2)
      months after the termination date. In any other circumstance, Tenant shall
      pay Landlord for each month, or part thereof, that Tenant retains

                                       19
<PAGE>

      possession of the Leased Premises or any part thereof after termination or
      expiration of the term of this Lease double the amount of the monthly rent
      then required by the terms hereof and also pay all damages sustained by
      Landlord by reason of such retention; but acceptance by Landlord of rent
      after such termination shall not constitute a renewal nor waive Landlord's
      right of re-entry or any other right.

(29)  RIGHTS RESERVED BY LANDLORD:

      Landlord shall have the following rights exercisable without notice and
      without liability to Tenant:

            (a)   To change the name or street address of the Building if
                  dictated by the town or state;

            (b)   To have pass keys to the Leased Premises;

            (c)   To require all persons entering or leaving the Building during
                  such hours as Landlord may from time to time reasonably
                  determine to identify themselves to a watchman by registration
                  or otherwise, and to establish their right to enter or leave,
                  and to exclude or expel any peddler, solicitor or beggar at
                  any time from the Developed Parcel or the Building;

            (d)   To approve the weight, size and location of safes, computers,
                  and other heavy articles or equipment in and about the Leased
                  Premises and to require all such items and other office
                  furniture and equipment to be moved in and out of the Building
                  only at such times and in such manner as Landlord shall direct
                  and in all events at Tenant's sole risk and responsibility;

            (e)   Intentionally Omitted;

            (f)   Landlord or its agents shall have the right to enter the
                  Leased Premises at reasonable times after at least one (1)
                  business day advance notice to Tenant, for the purpose of
                  inspecting the same, showing the same to prospective
                  purchasers and lenders, or making such alterations, repairs,
                  improvements or additions to the Leased Premises as Landlord
                  may deem necessary or desirable. Landlord may at any time
                  place on or about the Leased Premises any ordinary "For Sale"
                  signs; and,

            (g)   Within twelve (12) months prior to the date of the expiration
                  of this Lease, Landlord or its agents shall have the right to
                  enter the Leased Premises at all reasonable times after at
                  least one (1) business day advance notice to Tenant for the
                  purpose of exhibiting the Leased Premises to prospective
                  tenants, but Landlord shall not post a "For Lease" or other
                  similar sign at the Leased Premises until the last six (6)
                  months of the term.

(30)  BROKER'S COMMISSION

                                       20
<PAGE>

      Tenant represents that it has dealt directly with (and only with)
      Landlord's broker (identified in the letter attached as Exhibit I) in
      connection with this Lease and that no other broker negotiated or
      participated in the negotiations of this Lease or submitted or showed the
      Leased Premises to it or is entitled to any commission in connection
      therewith. Landlord shall be liable for the payment of any commission due
      to the broker named in this paragraph; however, if there is a violation of
      the representation herein made by Tenant, and any other broker claims a
      commission from Landlord, Tenant shall indemnify and hold the Landlord
      harmless from such claim.

(31)  ESTOPPEL CERTIFICATE:

      (a)   Tenant shall at any time upon not less than ten (10) days' prior
            written notice from Landlord execute, acknowledge and deliver to
            Landlord a statement in writing: (i) certifying that this Lease is
            unmodified and in full force and effect (or, if modified, stating
            the nature of such modification and certifying that this Lease as so
            modified, is in full force and effect) and the date to which rent
            and other charges are paid in advance, if any, and (ii)
            acknowledging that there are no uncured defaults on the part of
            Landlord hereunder, or specifying such defaults if any are claimed.
            Such statement shall be substantially in the form attached as
            Exhibit G, subject to reasonable modifications as may be required by
            such prospective purchaser, mortgagee, or Landlord mutually
            acceptable to Tenant, Landlord, and the mortgagee or prospective
            purchaser. Any such statement may be conclusively relied upon by any
            prospective purchaser or mortgagee of the Leased Premises.

      (b)   Tenant's failure to deliver such statement within ten (10) business
            days after receipt of Landlord's written request shall be a material
            default under this Lease.

      (c)   Intentionally Omitted.

(32)  LANDLORD'S LIABILITY:

      (a)   The term "Landlord" as used herein shall mean only the owner or
            owners at the time in question of the fee title. In the event of any
            transfer of such title, Landlord herein named (and in case of any
            subsequent transfers, then the grantor) shall be relieved from and
            after the date of such transfer of all liability as respects
            Landlord's obligations thereafter to be performed (but not from
            liability for obligations arising prior to the transfer date, for
            which Landlord shall remain liable to the extent of the net proceeds
            of the sale of the Developed Parcel), provided that: (i) any funds
            in the hands of Landlord or the then grantor at the time of such
            transfer, in which Tenant has an interest, shall be delivered to the
            grantee; (ii) the grantee shall assume and agree to be bound by the
            obligations arising under this Lease from and after the transfer
            date. The obligations contained in this Lease to be performed by
            Landlord shall, subject as aforesaid, be binding on Landlord's
            successors and assigns, only with respect to their respective
            periods of ownership.

      (b)   Tenant shall look solely to the estate and property of Landlord in
            the Developed Parcel for the collection of any judgment (or other
            judicial process) requiring the

                                       21
<PAGE>

            payment of money by Landlord in the event of any default or breach
            by Landlord with respect to any of the terms and provisions of this
            Lease to be kept, observed, and performed by Landlord, subject,
            however, to the prior rights of any mortgagee of all or any part of
            the property; no other assets of Landlord shall be subject to levy,
            execution or other judicial process for the satisfaction of Tenant's
            claim (except that Tenant may set-off the amount of any such
            judgment against rent and other amounts due under this Lease).
            Nothing in this Lease shall be construed in any event whatsoever to
            impose any personal liability upon the trustees, officers or the
            shareholders of the Landlord, or of the general or limited partners
            comprising the Landlord, as Landlord herein or otherwise. Nothing in
            Section 32(b) shall be interpreted to limit Tenant's right to seek
            injunctive relief or specific performance, or Tenant's right to
            claim the proceeds of insurance specifically maintained for Tenant's
            benefit.

(33)  INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS:

      This Lease including any exhibits, schedules or attachments, hereto,
      contains all agreements of the parties with respect to any matter
      mentioned herein. No prior agreement or understanding pertaining to any
      such matter shall be effective. This Lease may be modified in writing
      only, signed by the parties in interest at the time of the modification.
      Except as otherwise stated in this Lease, Tenant hereby acknowledges that
      neither any cooperating broker on this transaction nor the Landlord or any
      employees or agents of any of said persons has made any oral or written
      warranties or representations to Tenant relative to the condition or use
      by Tenant of said Leased Premises, the Building or the Developed Parcel.

(34)  WAIVERS:

      (a)   No waiver by either party of any provision hereof shall be deemed a
            waiver of any other provision hereof or of any subsequent breach by
            the other party of the same or any other provision. Landlord's
            consent to, or approval of, any act shall not be deemed to render
            unnecessary the obtaining of Landlord's consent to or approval of
            any subsequent act by Tenant.

      (b)   The acceptance of rent hereunder by Landlord shall not be a waiver
            of any preceding breach by Tenant of any provision hereof, other
            than the failure of Tenant to pay the particular rent so accepted,
            regardless of Landlord's knowledge of such preceding breach at the
            time of acceptance of such rent.

(35)  SEVERABILITY:

      If any provision of this Lease shall at any time be deemed to be invalid
      or illegal by any court of competent jurisdiction, this Lease shall not be
      invalidated thereby; and in such event this Lease shall be read and
      construed as if such invalid or illegal provision had not been contained
      herein.

(36)  RECORDING:

                                       22
<PAGE>

      This Lease shall not be placed of record; however, either Landlord or
      Tenant shall, upon request of the other, execute, acknowledge and deliver
      to the other a "short form" memorandum of this Lease on the form attached
      as Exhibit H, which may be recorded in Montgomery County, Ohio.

(37)  CUMULATIVE REMEDIES:

      No remedy or election hereunder shall be deemed exclusive but shall,
      wherever possible, be cumulative with all other remedies at law or in
      equity.

(38)  INTEREST ON PAST DUE OBLIGATIONS:

      Any amount owed by Tenant to Landlord which is not paid within five (5)
      days after the date said amount is due shall bear interest at the rate of
      fifteen percent (15%) per annum from the due date of such amount; except
      that because this charge is imposed in order to deter "frequent" offences,
      Landlord agrees to waive any such interest charge once during each
      calendar year of the Lease term and any renewal terms. However, interest
      shall not be payable on late charges to be paid by Tenant under this
      Lease. The payment of interest on such amounts shall not (in and of
      itself) excuse or cure any default by Tenant under this Lease. If the
      interest rate specified in this Lease is higher than the rate permitted by
      law, the interest rate is hereby decreased to the maximum legal interest
      rate permitted by law.

(39)  BINDING EFFECT:

      Subject to any provisions hereof restricting assignment or subletting by
      Tenant, this Lease shall be binding upon and inure to the benefit of the
      parties, their heirs, personal representatives, successors and assigns.

(40)  SUBORDINATION:

      (a)   The Tenant accepts this Lease subject and subordinate to any ground
            lease, mortgage, deed of trust, or any other hypothecation or
            security now or hereafter placed upon the Developed Parcel,
            notwithstanding the recording of the Memorandum of Lease, and to any
            and all advances made on the security thereof and to all renewals,
            modifications, consolidations, replacements and extensions thereof,
            and Landlord warrants that the mortgagee will deliver a
            subordination, non-disturbance and attornment agreement in the form
            attached as Exhibit J. If any mortgagee shall elect to have this
            Lease prior to the lien of its mortgage, and shall give written
            notice thereof to Tenant, this Lease shall be deemed prior to such
            mortgage, whether this Lease is dated prior or subsequent to the
            date of said mortgage, or the date of recording thereof.

      (b)   Although the provisions of Paragraph 40(a) shall be self operative,
            Tenant agrees, upon request of Landlord or Landlord's lender, to
            execute any documents required to effectuate any attornment, a
            subordination or to make this Lease prior to the lien of any
            mortgage, so long as such mortgagee executes a subordination,
            non-disturbance and attornment agreement in a form reasonably
            satisfactory to Tenant and the

                                       23
<PAGE>

            mortgagee. Tenant's failure to execute such documents within ten
            (10) business days after written demand shall constitute a material
            default by Tenant hereunder.

(41)  AUTHORITY:

      Each individual executing this Lease on behalf of either party represents
      and warrants that he or she is duly authorized to execute and deliver this
      Lease on behalf of said party and shall, at the execution of this Lease,
      deliver to the other party, satisfactory evidence of such authority.

(42)  CONFLICT:

      Any conflict between the printed provisions of this Lease and the
      typewritten or handwritten provisions shall be controlled by the
      typewritten or handwritten provision (provided each such change is
      initialed by both parties).

(43)  GOVERNING LAW; FORUM:

      This Lease is made under and is to be governed by the laws of the State of
      Ohio. Any action arising out of this Lease shall be brought only in a
      court of competent jurisdiction in Montgomery County, Ohio.

(44)  MECHANICS' LIEN:

      In the event Tenant performs any alterations in accordance with Paragraph
      17 of this Lease, Tenant will not cause or permit to stand, through any
      action taken by it, any mechanics', laborer's, materialman's or other lien
      against the Leased Premises or the Building or improvement thereon in
      connection with work of any character performed or material furnished to
      the Leased Premises. Nothing in this Lease may be construed as creating an
      agency relationship between Landlord and Tenant for purposes of performing
      alterations, improvements, or repairs. If Tenant in good faith desires to
      contest the validity or amount of any such lien landlord agrees to
      cooperate in the institution, defense and maintenance of any such action
      or proceeding, provided that Tenant will indemnify and hold Landlord
      harmless for and from any and all expenses, costs and liabilities in
      connection with any such contest. Any such action or proceeding may be
      instituted and maintained by Tenant only if and so long as the enforcement
      of any such lien, by sale or otherwise, will be stayed by reason of such
      action or proceeding or by bond filed or a monetary deposit paid into
      court as a part of such action or proceeding. Promptly after the
      determination of any such contest adverse to the Tenant and prior to the
      enforcement of any such lien, Tenant will pay and discharge the amount of
      any such lien, together with any related interest, costs and penalties.

(45)  FINANCIAL STATEMENTS:

      Within twenty (20) days of written request by Landlord, Tenant will
      provide Landlord with its most recent financial statement, certified to be
      true and correct by either Tenant's chief financial officer or an
      independent certified public accountant; provided, however, Landlord may
      share such statements only with its mortgagee, ground lessor, prospective
      mortgagees and ground lessors, purchasers and partners, and attorneys,
      accountants, and other advisors of

                                       24
<PAGE>

      Landlord and each of the foregoing. However, the Tenant is a public
      company trading on the NASDAQ Stock Market (WONE). The Tenant files
      current financial statements and other information with the Securities and
      Exchange Commission, published at www.sec.gov. Landlord agrees that so
      long as this information remains readily available to the public in this
      format (or in any future format similarly designed to facilitate public
      access to the information), then Tenant shall be construed to have
      complied with the financial disclosure requirements of this Section.
      Tenant represents and warrants that the financial statements and
      information presented and maintained on its website shall at all times be
      the most current financial statement for Tenant and that same shall at all
      times be true, accurate and complete and that Landlord shall be entitled
      to rely upon such information for all purposes of this Lease.

(46)  JOINT VENTURE:

      This Lease may not be deemed or construed to create or establish any
      relationship of partnership, agency, or joint venture (or any other
      similar relationship or arrangement) between Landlord and Tenant.

(47)  HAZARDOUS SUBSTANCES:

      The term "Hazardous Substance" shall be interpreted broadly to include
      those substances defined as a "hazardous substance", "pollutant" or
      "contaminant" pursuant to the Compensation Liability Act, 72 U.S.C., 9061
      et sec, as amended and regulations thereunder, or any federal, state or
      local regulation or ordinance; and shall also specifically include without
      limitation petroleum and petroleum based derivatives, distillates and
      byproducts, asbestos; and any hazardous waste or other similar material.

      Tenant warrants and represents that it shall not use, store, treat,
      accumulate or transport Hazardous Substances at, on, to or from the Leased
      Premises during the Lease Term except in the ordinary conduct of its
      business and in a manner that complies with all federal, state, and local
      laws, regulations, and ordinances. Tenant additionally warrants and
      represents that Tenant's occupancy of the Leased Premises and its
      activities thereon shall not cause or result in any release, leak,
      discharge, spill, disposal, or emission of Hazardous Substances at, in,
      on, from or under the Leased Premises during or following the Lease Term.

      Tenant agrees to indemnify and hold Landlord harmless from any and all
      claims, damages, fines, judgements, penalties, costs, liabilities, or
      losses (including, without limitation reasonable sums paid for settlement
      of claims, attorneys fees, consultant and expert fees) arising during or
      after the Lease Term from or in connection with the presence of any
      Hazardous Substances in, on or under the Leased Premises during or after
      the Lease Term where the presence of such Hazardous Substances is caused
      by or arises from Tenant's occupancy of the Leased Premises or otherwise
      from Tenant's activities. Without limitation the foregoing, this
      Indemnification shall include reasonable costs incurred due to any
      investigation of the Leased Premises or any clean-up, removal or
      restoration mandated by a federal, state or local agency or political
      subdivision with respect to any such Hazardous Substance present on the
      Leased Premises during the Lease Term. The provisions of this paragraph
      shall survive the expiration or termination of this Lease.

                                       25
<PAGE>

      Landlord warrants and represents that, to the best of its knowledge, any
      use, storage, treatment, accumulation, or transportation of Hazardous
      Substances which has occurred in or on the Developed Parcel prior to the
      date hereof has been in compliance with the applicable federal, state, or
      local laws, regulations, and ordinances. Landlord additionally warrants
      and represents that, to the best of its knowledge, no release, leak,
      discharge, spill, disposal, or emission of Hazardous Substances has
