State of South Carolina
County of Richland

                                 LEASE AGREEMENT
                                 ---------------

         This Agreement, made this 18th day of October, 2001 by and between T&L
A Partnership of South Carolina, hereinafter referred to as Landlord, and
Advanced Biosensor, Inc., hereinafter referred to as Tenant.

                                   WITNESSETH

         That Landlord, for and in consideration of the rents, covenants and
agreements herein contained to be paid and agreed to be performed by Tenant,
does hereby warrant and lease to Tenant the following described property.

         PREMISES. All of that office space containing approximately 10,080
         square feet as measured from the window surface of the outer building
         walls in the County of Richland, State of South Carolina, and
         hereinafter referred to as the "Leased Premises" located at No. 6
         Woodcross Drive, Harbison Industrial Park, Columbia, SC 29212.

         TERM. The term of this Lease shall be for a period of three (3) years,
         commencing on the 1st day of November, 2001 and expiring on the last
         day of October, 2004.

         RENTAL. Tenant shall pay to Landlord promptly on the first day of each
         month in advance during the term of this Lease a monthly rental which
         shall be payable to T&L A Partnership (See Addendum "A"). In the event
         Tenant shall fail to pay any rental on the due date or within ten (10)
         days thereafter, late charges of six (6) percent of the monthly rental
         shall be added to the rental for each such late payment, and the same
         be treated as additional rent.

         NOTICES. Until otherwise notified in writing by Landlord, Tenant shall
         make payment of rental and give notices to Landlord at 1016 Calks Ferry
         Road, Lexington, SC 29072, attention of Gary L. Traywick, General
         Partner. Landlord shall give notices and other communications to Tenant
         by mailing same to:

                  Advance Biosensor, Inc.
                  No. 6 Woodcross Drive
                  Columbia, SC  29212

         SECURITY DEPOSIT. The Security Deposit of $6,720.00 not on deposit with
         the Landlord will be retained as security during the term of this Lease
         for the faithful performance and observance of Tenant of the terms of
         this Lease. In the event Tenant defaults with respect to any of the
         terms of this Lease including, but not limited to, the payment of rent,
         Landlord may use the whole or any part of the deposit to the extent
         required, but Tenant shall remain liable for any additional amounts
         due. If Tenant shall comply fully with all of the terms of this Lease,
         the security deposit shall be returned to

                                       2
<PAGE>

         Tenant upon the expiration of the lease term. In the event of the sale
         or lease of the property of which the leased premises are a part,
         Landlord shall have the right to transfer the unused security deposit
         to the new purchaser or lessee who shall be responsible to the Tenant
         for the security deposit and Landlord shall be released from all
         liability for its return.

         USE. The premises shall be used for the normal operating practices of
         Tenant's business, but shall not be used for any illegal purpose, nor
         in any way that would increase the rate of insurance or invalidate the
         insurance coverage on the premises, nor in any manner interfere with or
         infringe upon the rights of Landlord. Tenant shall at all times abide
         by the Rules and Regulations which are attached to and hereby expressly
         made a part of this Lease.

         1.       IMPROVEMENTS. Landlord agrees to allow Tenant to make changes
                  to interior floor plan of building with prior notification in
                  writing as to extent and type of modification. Tenant agrees
                  to return building and interior to original configuration or
                  negotiated monetary settlement for reconfiguration if deemed
                  necessary by Landlord, prior to release of responsibilities of
                  this Lease. All additions, alterations, and improvement
                  allowed by Landlord shall be deemed to be the property of the
                  Landlord and shall not be removed by Tenant without Landlord's
                  consent. All additions, alterations, and improvements to
                  grounds and building shall be done at Tenant's expense.

         2.       QUIET POSSESSION. Landlord warrants that is seized with good
                  and sufficient title to the entire premises, and further
                  covenants that if Tenant shall discharge the obligations
                  herein set forth to be performed by Tenant, the Tenant shall
                  have and enjoy the quiet and undisturbed possession of the
                  leased premises without hindrance or interference from
                  Landlord or any other person lawfully claiming by, through or
                  under Landlord.

         3.       SERVICES. Tenant shall provide at his own expense a HVAC
                  service contract for all maintenance and repair of
                  heating/cooling units. Tenant is responsible for all
                  maintenance and repair of the interior and exterior of the
                  building and grounds, with the exception of the roof and
                  structural damage which shall remain the Landlord's
                  responsibility. (See Addendum "A").

         4.       PROPERTY TAXES, INSURANCE AND OPERATING EXPENSES. Landlord
                  agrees to pay property taxes within fifteen (15) days or on
                  before January 15 of each year of lease term. Tenant shall
                  obtain property insurance in at least the same coverage as
                  Landlord provided prior to lease, naming T&L as additional
                  insured, and maintaining such coverage for the term of this
                  Lease or extension.

         5.       DAMAGE TO PREMISES. If the leased premises are damaged or
                  destroyed by fire or other casualty, Landlord shall begin
                  repair or restoration of the leased premises within sixty (60)
                  days after the date full insurance is paid to Landlord and if
                  not begun within this time period the Tenant shall have the
                  option of terminating this Lease; provided, however, that if
                  the said damage shall occur

                                       3
<PAGE>

                  within six (6) months of the expiration date of this Lease,
                  Landlord shall have the right within fifteen (15) days to
                  elect to terminate this Lease; and provided, further, that
                  should the building in which the leased premises are located
                  be damaged by fire or other casualty to such an extent that
                  Landlord determines to discontinue the leasing of office space
                  in the building, then Landlord shall have the right within
                  fifteen (15) days to elect to terminate this Lease. If the
                  damage or destruction to the leased premises was caused
                  without fault of Tenant, the rental required by this Lease
                  shall abate proportionately to the extent that the premises
                  are untenable by Tenant. In the event of the termination of
                  this Lease, the term hereby granted shall cease, rent shall be
                  apportioned and paid to the date of such damage, and Tenant
                  shall not be liable for any further rent after such
                  termination. All furniture, trade fixtures, files and other
                  property of Tenant located at the leased premises shall be at
                  the sole risk of Tenant, and Landlord shall not in any way be
                  liable for damage to such property of Tenant.

                  Except as may be otherwise be provided in this Lease, Landlord
                  and Tenant mutually agree that in the event of loss or damage
                  to the entire premises, the leased premises and/or any
                  contents, each party shall look first to any insurance in its
                  favor before making any claim against the other party, and to
                  the extent possible without additional cost, each part shall
                  obtain for each policy of such insurance provisions permitting
                  waiver of any claim against the other party for loss or damage
                  within the scope of its insurance, and each party to such
                  extent permitted for itself and its insurers waives all such
                  insured claims against the other party.

         6.       MAINTENANCE AND REPAIRS. Tenant shall keep the leased premises
                  in good care during the term of this Lease and shall surrender
                  same with keys thereto at the end of the lease term in good
                  and clean condition, reasonable wear and tear and damage by
                  fire or other casualty excepted.

         7.       RIGHT OF ENTRY. Landlord shall have the right to enter the
                  leased premises at reasonable hours to examine the same, or to
                  install plumbing, electrical, telephone or mechanical lines,
                  or to make such repairs, additions or alterations as it shall
                  deem necessary, or to exhibit the same to prospective
                  purchasers, or to exhibit the premises beginning ninety (90)
                  days prior to the expiration of the lease term to
                  prospectives.

         8.       ASSIGNMENTS. Landlord agrees that Tenant can assign or sublet
                  in whole or in part any portion of the premises. Any assignee
                  or sublessee must agree to abide by all of the terms of this
                  Lease, and Tenant shall not be relieved from any of its
                  obligations assumed under this Lease.

         9.       SUBORDINATION. Tenant agrees that its rights under this Lease
                  shall at all times by subordinated to the lien or any and all
                  mortgages, ground or underlying leases, or to the lien
                  resulting from any other method of financing or financing now
                  or hereafter in force against the land and/or building of
                  which the leased premises are a part provided that the
                  mortgagee or other lienholder shall agree


                                       4
<PAGE>

                  that so long as the Tenant is not in default under the terms
                  hereof, Tenant's rights under said Lease shall not be
                  disturbed and that if on account of foreclosure or sale
                  pursuant to the terms of any such security instruction the new
                  owner will attorn to the Tenant and complete the Landlord's
                  obligations under this Lease provided the Tenant is not then
                  and does not thereafter default under the terms hereof. Tenant
                  agrees to execute any documents which may be required to
                  effectuate the subordination.

         10.      CONDEMNATION. If any time during the term of this Lease the
                  entire property or any such substantial part as may render it
                  unsuitable for its current use is taken for a public or
                  quasi-public use under statute or any right of eminent domain,
                  then in such event, when title vests in the condemning
                  authority, the term of this Lease shall immediately cease and
                  the Lease shall terminate. Tenant shall have no claim against
                  the award made to Landlord for such taking or against Landlord
                  for the value of any unexpected term of this Lease.

         11.      HOLD HARMLESS. Tenant agrees to indemnify and save Landlord
                  harmless against any and all claims, demands, damages, cost
                  and expenses, including reasonable attorney's fees for the
                  defense thereof existing from the conduct of the management of
                  the business operated by Tenant to the leased premises or from
                  any breach or default on the part of Tenant of any covenant or
                  provision of this Lease or from any act of Tenant, its
                  employees or agents, and Tenant agrees to defend any such
                  action or proceeding by counsel reasonably satisfactory to
                  Landlord. Landlord shall not be responsible for the
                  carelessness or negligence of other tenants. Landlord agrees
                  to hold Tenant harmless for injury to any person by virtue of
                  any structural or other defect in the building occupied by
                  Tenant.

         12.      DEFAULT. If Tenant shall fail to pay the base rent or any
                  additional rent as provided within this Lease or shall fail to
                  perform any of the covenants and agreements required under
                  this Lease, or if Tenant shall vacate or abandon the leased
                  premises prior to the expiration of the term of this Lease or
                  suffer the lease to be taken under any writ of execution, or
                  if a petition to bankruptcy, insolvency or for reorganization
                  is filed by or against Tenant, or if Tenant shall make an
                  assignment for the benefit of creditors, then in any of such
                  events, Landlord may deem Tenant to be in default under this
                  Lease and if such default is not remedied to Landlord's
                  satisfaction within fifteen (15) days after written notice of
                  such default is delivered to Tenant, Landlord may at its
                  option terminate this Lease and all rents then due and which
                  would become due during the remainder of the term, together
                  with such special damages that Landlord may suffer, shall
                  immediately become due and payable. Landlord shall also have
                  the right of re-entry and repossession of the leased premises
                  and may expel Tenant and remove all property therefrom with
                  the right to sell same and apply the proceeds against any
                  amounts due under this Lease. Landlord may at its option
                  without terminating this Lease have full right of entry and
                  may make such reasonable alterations and repairs as may be
                  needed in order to relet the leased premises or any part
                  thereof upon such rental, terms and conditions as it deems
                  advisable, and Tenant shall remain liable to Landlord for any
                  deficiency between the rent reserved hereunder


                                       5
<PAGE>

                  for the remainder of the term and the rental, if any, obtained
                  by Landlord in reletting. The failure of Landlord to relet the
                  premises shall not in any way release or reduce Tenant's
                  liability.

         13.      ATTORNEY'S FEES. If Tenant defaults in the performance of any
                  of the covenants of this Lease and by reason thereof Landlord
                  employs the services of an attorney to enforce performance by
                  Tenant, to evict Tenant, to collect monies due by Tenant, or
                  to perform any service based upon said default, then the
                  Tenant shall pay a reasonable attorney's fee and all
                  reasonable expenses and costs incurred by Landlord pertaining
                  thereto.

         14.      NON-WAIVER. The failure of Landlord or Tenant to insist upon
                  strict performance of any of the terms, conditions and
                  covenants herein shall not be deemed to be a waiver of any
                  rights or remedies that Landlord or Tenant may have, and shall
                  not be deemed a waiver of any subsequent breach or default in
                  the term, conditions and covenants herein contained except as
                  may expressly be waived in writing.

         15.      HOLDING OVER. In the event Tenant shall continue to remain in
                  and occupy the premises with the consent of Landlord after the
                  expiration of the term of this Lease, such holding over shall
                  not be deemed in any way to be a renewal or extension of the
                  term of this Lease, but shall constitute a tenancy from month
                  to month only, subject to all the covenants and conditions of
                  this Lease, other than those relating to the term hereof, for
                  which tenancy Tenant agrees to pay Landlord a mutually agreed
                  upon month-by-month rental.

         16.      NON-EASEMENT. It is understood and agreed that this Lease does
                  not grant any rights to light and air over property adjoining
                  the land on which the leased premises are situated.

         17.      GENERAL.

                  A.       This Agreement shall be governed by and construed
                           according to the laws of the State of South Carolina.

                  B.       The captions and titles appearing within this Lease
                           are for reference only and shall not be considered a
                           part of this Lease or in any way to modify, amend or
                           affect the provisions thereof.

                  C.       The proper grammatical changes shall be understood
                           and shall apply where necessary to designate the
                           plural rather than the singular and the masculine or

                           and Tenant, concerning the leased premises. No
                           subsequent alteration or amendment shall be binding
                           upon Landlord or Tenant unless reduced to writing and
                           signed by each party.

                  F.       Landlord does not in any way or for any purpose
                           become a partner of Tenant in the conduct of its
                           business, or otherwise, or a joint venturer or a
                           member of a joint enterprise with Tenant.

                  G.       The conditions, covenants and agreements contained in
                           this Lease shall be binding upon and inure to the

                           successors, heirs, executors, administrators and
                           assigns. No rights, however, shall inure to the
                           benefit of any assignee of Tenant unless the
                           assignment to such assignee has been made in
                           accordance with the provisions set out in this Lease.
