Term 4.             The term of this lease shall be for five (5) years,
                    commencing on the Ist day of June, 2006, and ending on the
                    31st day of May, 2011, both dates inclusive. If the leased
                    premises are not available or ready for occupancy at such
                    commencement date, and such unavailability or unreadiness is
                    not occasioned or caused by Tenant, (such as Tenant's
                    failure promptly to approve plans, make material or color
                    selections, make improvements to the leased premises which
                    are to be made by Tenant or make other decisions necessary
                    to the preparation of the leased premises for occupancy),
                    then the commencement date shall be the first day of the
                    month succeeding the month in which the lease premises are
                    available and ready for occupancy, as evidenced by written
                    notice given by Landlord to Tenant, and the termination date
                    should be extended accordingly. After the commencement and
                    termination dates have been determined as aforesaid, and
                    upon the demand of either the Landlord or the Tenant, the
                    parties hereto will execute a written declaration expressing
                    the specific commencement and termination dates. If by
                    mutual consent of the parties Tenant takes possession of the
                    leased premises prior to the commencement date, then during
                    such pre-term occupancy shall not affect the lease term as
                    herein otherwise established. If by mutual consent of
                    parties Tenant shall remain in possession of the leased
                    premises after the expiration of the term of this lease,
                    such possession shall be as a month to month tenancy during
                    which time the rent shall be payable at the same rate as
                    that in effect during the last month of the term, and the
                    provisions of this lease shall be applicable.

Rent 5.             Tenant shall without deduction, abatement or set-off of any
                    nature whatsoever, pay to Landlord as fixed rent for the
                    lease premises the sum of One Hundred Twenty, One Thousand
                    Two Hundred Seventy Five and 00/100 Dollars ($121,275.00)

                    One Hundred and Six and 25/100 Dollars ($10,106.25) each, in

                    month during the term of this lease. Rent may be paid up to
                    the 15th of the month without any penalties.

                           Upon execution of this Lease by both parties, and
                    prior to Tenants occupancy, Tenant shall deposit with
                    Landlord on demand the first month's rent of $10,106.25 and
                    a security deposit of $5000.00. Upon termination of this
                    lease, the security deposit shall be returned to the Tenant
                    if the leased premises are turned over to Landlord in the
                    same condition as at the commencement of this lease,
                    ordinary wear and tear excepted and no adjustment payments
                    are due. If any repairs are required due to Tenants abuse or
                    neglect, Tenant shall be responsible for the cost of the
                    repairs or replacement. Landlord shall use the security
                    deposit for full or partial payment of any repair or
                    replacement costs which are a result of Tenant's abuse or
                    neglect and charge the Tenant for any cost over and above
                    the amount of the security deposit. If costs and adjustments
                    chargeable against the security deposit are less than the
                    amount of the security deposit, the portion of the security
                    deposit in excess of such charges shall be returned to
                    Tenant.

Taxes 6.            The Tenant shall pay to the Landlord, as additional rent,
                    the proportionate part of any increases in real estate taxes

                    the fire and extended coverage insurance premium on the land
                    and building of which the leased premises are a part over
                    and above the amount thereof assessed for the calendar year
                    during which the term of this lease commences. Such
                    additional rent shall be payable by Tenant upon presentation
                    to Tenant of copies of paid statements for the

                                        2


                    year for which payment is demanded and copies of the paid
                    statement for the base year as above determined. The
                    proportion of such increase payable by Tenant shall be based
                    on the ratio which the number of square feet of gross area
                    occupied by the Tenant in the building bears to the total
                    number of square feet of gross area in the entire building.

                    consent of Landlord, which consent shall not be unreasonably
                    withheld. Landlord's consent to one assignment or subletting
                    shall not be deemed a consent to any other or further
                    assignment thereunder and no acceptance by Landlord of any
                    rent or any other sum of money from any assignee or

                    sub-lease. In the event that Tenant shall receive any
                    valuable consideration for an assignment of the Tenant's
                    interest in this lease, then, notwithstanding any other
                    provision contained in this lease to the contrary, Tenant

                           Prior to the commencement of this lease, Landlord
                    shall provide Tenant with proof of property and casualty

                    leased premises: nor for any personal injury to Tenant, its
                    officers, agents, employees and invitees, nor any other
                    occupant of any part of the leased premises, nor for any
                    damages to any property of the Tenant or of any other
                    occupant of any part of the leased premises, Irrespective of
                    how much such injury or damage may be caused, whether from
                    action of the elements or acts by occupants of adjacent
                    properties, but this section does not apply to any acts of
                    negligence of Landlord.

                    Tenant shall indemnify and hold Landlord harmless from any
                    loss, damages and expenses incident thereto arising out of
                    liability to any person on account of loss of or damage to
                    property or injury to persons resulting from the use and
                    occupancy of the leased premises or the parking lot,
                    sidewalks, drives, or common area by Tenant.

Limitation of       Anything contained in this Lease to the contrary
Liability 19.       notwithstanding, Tenant agrees that Tenant shall look solely
                    to the estate and property of Landlord in the land and
                    Buildings of which the Leased Premises forms a part, in the
                    event of any default or breach by Landlord with respect to
                    any of the terms and provisions of this Lease.

Damage or           The destruction of the building and improvements on the
Destruction 20.     leased premises by fire or other casualty or such material
                    Injury thereto so as to render the premises In question
                    untenable for one hundred twenty (120) days shall produce
                    and work a termination of this lease. Provided, however,
                    that if such destruction of or damage to the premises shall
                    be due to the act or negligence of Tenant, its officers,
                    agents, or employees, the Landlord shall have the option to
                    produce and work a termination of this lease or to restore
                    the premises to substantially the same condition in which
                    they existed prior to such destruction or damage.

                           If the Landlord and Tenant cannot agree as to whether
                    said building and improvements are unquestionably untenable
                    for one hundred twenty (120) days, the fact shall be
                    determined by arbitration; the Landlord and Tenant shall
                    each choose an arbitrator within five (5) days after either
                    has notified the other in writing of such damage. The two
                    arbitrators so chosen, before entering on the discharge of
                    their duties, shall elect a third, and the decision of any
                    two of such arbitrators shall be conclusive and binding upon
                    both parties hereto. If it is determined by arbitration, or
                    agreement between the Landlord and Tenant, that said
                    premises are not unquestionably untenable for one hundred
                    twenty (120) days, then Landlord shall restore said premises
                    to substantially the same condition in which they existed
                    prior to such damage, at Landlord's own expense, with all
                    reasonable speed and promptness, and in such case a just and
                    proportionate part of said rental shall be abated until said
                    premises have been restored. In determining what constitutes
                    reasonable speed and promptness, considerations shall be
                    given to delays caused by strikes, adjustment of insurance,
                    and other causes beyond the Landlord's control.

                           In no event shall the Landlord be required to restore
                    any alteration, additions or Improvements made by or for the
                    Tenant and not required by this Lease to be furnished by
                    Landlord, nor any trade fixtures, furniture, equipment or
                    other property belonging to Tenant.

Condemnation 21.           (a)      If the whole of the leased premises shall be
                    taken for any public or any quasi-public use under any
                    statute or by right of eminent domain, or by purchase under
                    threat of condemnation, then this lease shall automatically
                    terminate as of the date that title shall be taken. If any
                    part of the leased premises shall be so taken as to render
                    the remainder thereof unusable for the purposes for which
                    the leased premises were leased, then the Landlord and
                    Tenant shall each have the right to terminate this lease on
                    thirty (30) days notice to the other given within ninety
                    (90) days after the date of such taking. In the event that
                    this lease shall terminate or be terminated, the rental,
                    shall, be adjusted to cease on the date of such termination.

                           (b)      If any part of the leased premises shall be
                    so taken and this lease shall not terminate or be terminated
                    under the provisions of subparagraph (a) above, then the
                    rental shall be equitably apportioned according to the space
                    so taken, and the Landlord shall, at its own cost and
                    expense, restore the remaining portion of the leased
                    premises to the extent necessary to render them reasonably
                    suitable for the purposes for which they were leased, and
                    shall make all repairs to the building in which the leased
                    premises are located to the extent necessary to constitute
                    the building a complete architectural unit.

                           (c)      All compensation awarded or paid upon such a
                    total or partial taking of the leased premises shall belong
                    to and be the property of the Landlord without any
                    participation by the Tenant: provided, however, that nothing
                    contained herein shall be construed to preclude the Tenant
                    from prosecuting any claim directly against the condemning
                    authority in such condemnation proceeding for loss of
                    business, depreciation to, damage to, or cost of removal of,
                    or for the value of stock, trade fixtures, furniture, and
                    other personal property belonging to the Tenant provided,
                    however, that no such claim shall diminish or otherwise
                    adversely affect the Landlord's award.

Default 22.         The following events shall be deemed to be events of default
                    by Tenant under this lease: (i) if Tenant shall fail to pay
                    any fixed or additional rent hereby reserved when due (ii)
                    if Tenant shall fail to comply with any term or provision,
                    or covenant of this lease, other than the payment of rent
                    (iii) if Tenant shall become insolvent, or shall make a
                    transfer In fraud of its creditors, or shall make an
                    assignment for the benefit of its creditors (iv) if Tenant
                    shall file a petition under any section or chapter of the
                    National Bankruptcy Act, as amended, or under any similar
                    law or statute of the United States or any state thereof, or
                    Tenant shall be adjudicated bankrupt or Insolvent in
                    proceedings filed against Tenant thereunder (v) if a
                    receiver or trustee shall be appointed for substantially all
                    of the assets of Tenant, or (vi) if Tenant shall desert or
                    vacate any substantial portion of the leased premises. In
                    all cases above Tenant shall have ten (10) days to cure such
                    failure or default following written notice from Landlord.

                           Upon the occurrence of any such event of default,
                    Landlord shall have the option to pursue any one or more of
                    the following remedies (as well as any other remedies
                    provided by Law) without any notice or demand whatsoever.

                    (a)    Terminate Tenants right to possession of the leased
                           premises (without terminating this lease or Tenants
                           obligations hereunder) and enter upon and take
                           possession of the leased premises by summary
                           proceedings, force or in any other manner, and
                           dispossess, expel, and remove the Tenant or any other
                           person who may be occupying the leased premises or
                           any part thereof (including changing or altering the
                           locks or other security devices) and remove and expel
                           any personal property of trade fixtures located
                           therein, all without being liable to any prosecution
                           therefore or for any damages resulting therefore. In
                           such event Landlord shall also have the option to
                           declare immediately due and payable and to

                           for the balance of the lease term. In the event of
                           such re-entry by Landlord, Landlord shall also have
                           the option to allow the leased premises to remain
                           vacant or relet same for the account of Tenant (in
                           the name of Landlord or in the name of Tenant) at any
                           rent and for any term readily obtainable and receive
                           the rent therefore, in which event all rents that may
                           arise by reason of such relettlng (after first
                           deducting all repossession costs, brokerage
                           commission, legal expenses, attorney's fees and all
                           other expenses in cleaning, altering premises for
                           reletting) shall be paid over to Tenant or credited
                           to Tenant's account.

                    (b)    Forfeit and terminate this lease and Tenant's right
                           to possession of the leased premises. In the event of
                           such termination Tenant shall immediately surrender
                           the leased premises to Landlord and if Tenant fails
                           to do so, Landlord may enter upon and take possession
                           of the leased premises and expel or remove tenant and
                           any other person who may be occupying said premises
                           or any part thereof, and any personal property or
                           trade fixtures located therein. In the event of a
                           forfeiture of the lease as herein provided, Tenant
                           agrees that the security deposit being held by
                           Landlord hereunder shall be forfeited to Landlord as
                           liquidated damages for Tenant's default, which
                           liquidated damages shall be in addition to and not in
                           lieu of any unpaid rent or any other damages accruing
                           to Landlord by reason of the violation by Tenant of
                           any of the terms, provisions and covenants of this
                           lease.

                           Pursuit by Landlord of any of the foregoing remedies
                    or any other remedy provided by law shall not constitute a
                    forfeiture or waiver of any rent due to Landlord hereunder
                    or of any damages accruing to Landlord by reason of the
                    violation by Tenant of any of the terms, provisions and
                    covenants of this lease. In no event shall Tenant be
                    relieved from its obligation to pay the rentals specified in
                    this lease by reason of a surrender of possession,
                    termination of this lease or in any other manner whatsoever,
                    unless specifically agreed to in writing by Landlord.

                    No waiver by Landlord of any violation or breach of any of
                    the terms, provisions and covenants of this lease shall be
                    deemed or construed to constitute a waiver of any other
                    violation or breach of any of the terms, provisions and
                    covenants herein contained. Forbearance by Landlord to
                    enforce one or more of the remedies herein provided upon an
                    event of default shall not be deemed or construed to
                    constitute a waiver of such default.

                           If Landlord incurs any expenses, including court
                    costs and attorney's fees, as a result of a default by
                    Tenant under this lease, then such expenses shall be
                    reimbursed by Tenant as additional rent, whether or not such
                    default is subsequently cured.

                           Tenants delinquent payments shall bear interest at
                    the rate of 18% per annum from the date of delinquency until
                    paid.

                    impairs the health, safety or condition or any person or

                    value of the Premises or the surrounding property. This
                    covenant excludes the storage of small quantity samples

                    this paragraph. Tenant shall indemnify and hold Landlord and

                    interest of Landlord under this Lease, Tenant shall be bound

                    thereof remaining, with the same force and effect as if said

                    execution of any further instrument on the part of either
                    parties hereto, immediately upon the mortgage succeeding to
                    the interest of Landlord under this lease.

                    successors, and assigns of each of the parties, except that
                    no assignment or subletting by Tenant without the written

                    all of its terms and conditions. Such option shall be
                    exercised by written notice to Landlord, not less than six
