                                 LEASE AGREEMENT

      THIS LEASE AGREEMENT (hereinafter called the "Lease") is made and entered
into this 20th day of December, 2001, by and between MEADOW BROOK NORTH, L.L.C.,
a Delaware limited liability company (hereinafter called "Landlord"); and
EMAGEON, INC., a Delaware corporation (hereinafter called "Tenant").

      1.    PREMISES. Landlord does hereby rent and lease to Tenant and Tenant
does hereby rent and lease from Landlord, for general office purposes of a type
customary for first-class office buildings, the following described space
(hereinafter called the "Premises"):

2,128 rentable square feet of space located on the fourth floor of a five-story
building (the "Building") located on the real property described in Exhibit "A"
attached hereto (the "Property"), said Premises to be located as shown by
diagonal lines on the drawing attached hereto as Exhibit "A-1" and made a part
hereof by reference. The Building is located within a larger office park (the
"Project") consisting of approximately 180 acres, together with any and all
improvements now or hereafter located thereon and together with any additional
land and/or buildings which Landlord hereinafter acquires and makes a part of
the Project. The Premises shall be prepared for Tenant's occupancy in the manner
and subject to the provisions of Exhibit "B" attached hereto and made a part of
hereof. As used in this Lease, "rentable square feet" shall be determined based
upon the ANSI Z.65-1996 standard promulgated by the Building Owners and Managers
Association.

      2.    LEASE TERM. Tenant shall have and hold the Premises for a term
("Term") commencing on January 1, 2002 (the "Commencement Date") and terminating
at midnight on December 31, 2004 (the "Expiration Date"), unless sooner
terminated or extended as hereinafter provided.

      3.    BASE RENT. Tenant shall pay to Landlord, at c/o Daniel Realty
Services, L.L.C., 3595 Grandview Parkway, Suite 400, Birmingham, Alabama 35243,
or at such other place as Landlord shall designate in writing to Tenant, annual
base rent ("Base Rent") in the amounts set forth in the Base Lease Provisions.
The term "Lease Year", as used in the Basic Lease Provisions and throughout this
Lease, shall mean each and every consecutive twelve (12) month period during the
Term of this Lease, with the first such twelve (12) month period commencing on
the Commencement Date; provided, however, if the Commencement Date occurs other
than on the first day of a calendar month the first Lease Year shall be that
partial month plus the first full twelve (12) months thereafter.

      4.    RENT PAYMENT. The Base Rent for each Lease Year shall be payable in
equal monthly installments, due on the first day of each calendar month, in
advance, in legal tender of the United States of America, without abatement,
demand, deduction or offset whatsoever, except as may be expressly provided in
this Lease. One full monthly installment of Base Rent shall be due and payable
on the date of execution of this Lease by Tenant for the first month's Base Rent
and a like monthly installment of Base Rent shall be due and payable on or
before the first day of each calendar month following the Commencement Date
during the Term hereof; provided, that if the Commencement Date should be a date
other than the first day of a calendar month, the monthly Base Rent installment
paid on the date of execution of this Lease by Tenant shall be prorated to that
partial calendar month, and the excess shall be applied as a credit against the
next monthly Base Rent installment. Tenant shall pay, as Additional Rent, all
other sums due from Tenant under this Lease (the term "Rent", as used herein,
means all Base Rent, Additional Rent and all other amounts payable hereunder
from Tenant to Landlord).

      5.    LATE CHARGE. Other remedies for non-payment of Rent notwithstanding,
if any monthly installment of Base Rent or Additional Rent is not received by
Landlord on or before the date due, or if any payment due Landlord by Tenant
which does not have a scheduled due date is not received by Landlord on or
before the tenth (10th) business day following the date Tenant was invoiced, a
late charge of five percent (5%) percent of such past due amount shall be
immediately due and payable as Additional Rent

<PAGE>

and interest shall accrue from the date past due until paid at the lower of
eighteen percent (18%) per annum or the highest rate permitted by applicable
law.

      6.    PARTIAL PAYMENT. No payment by Tenant or acceptance by Landlord of
an amount less than the Rent herein stipulated shall be deemed a waiver of any
other Rent due. No partial payment or endorsement on any check or any letter
accompanying such payment of Rent shall be deemed an accord and satisfaction,
but Landlord may accept such payment without prejudice to Landlord's right to
collect the balance of any Rent due under the terms of this Lease or any late
charge assessed against Tenant hereunder.

      7.    CONSTRUCTION OF THIS AGREEMENT. No failure of Landlord to exercise
any power given Landlord hereunder, or to insist upon strict compliance by
Tenant of his obligations hereunder, and no custom or practice of the parties at
variance with the terms hereof shall constitute a waiver of Landlord's right to
demand exact compliance with the terms hereof. Time is of the essence of this
Lease.

      8.    USE OF PREMISES.

            (a)   Tenant shall use and occupy the Premises for general office
purposes of a type customary for first-class office buildings and for no other
purpose. The Premises shall not be used for any illegal purpose, nor in
violation of any valid regulation of any governmental body, nor in any manner to
create any nuisance or trespass, nor in any manner to vitiate the insurance or
increase the rate of insurance on the Premises or the Building, nor in any
manner inconsistent with the first-class nature of the Building.

            (b)   Tenant shall not cause or permit the receipt, storage, use,
location or handling on the Property (including the Building and Premises) of
any product, material or merchandise which is explosive, highly inflammable, or
a "hazardous or toxic material," as that term is hereafter defined. "Hazardous
or toxic material" shall include all materials or substances which have been
determined to be hazardous to health or the environment, including, without
limitation hazardous waste (as defined in the Resource Conservation and Recovery
Act); hazardous substances (as defined in the Comprehensive Emergency Response,
Compensation and Liability Act, as amended by the Superfund Amendments and
Reauthorization Act); gasoline or any other petroleum product or by-product or
other hydrocarbon derivative; toxic substances, (as defined by the Toxic
Substances Control Act); insecticides, fungicides or rodenticide, (as defined in
the Federal Insecticide, Fungicide, and Rodenticide Act); asbestos and radon and
substances determined to be hazardous under the Occupational Safety and Health
Act or regulations promulgated thereunder. Notwithstanding the foregoing, Tenant
shall not be in breach of this provision as a result of the presence in the
Premises of de minimis amounts of hazardous or toxic materials which are in
compliance with all applicable laws, ordinances and regulations and are
customarily present in a general office use (e.g., copying machine chemicals and
kitchen cleansers).

      9.    DEFINITIONS. "Landlord," as used in this Lease, shall include the
party named in the first paragraph hereof, its representatives, assigns and
successors in title to the Premises. "Tenant" shall include the party named in
the first paragraph hereof, its heirs and representatives, and, if this Lease
shall be validly assigned or sublet, shall also include Tenant's assignees or
subtenants, as to the Premises, or portion thereof, covered by such assignment
or sublease. "Landlord" and "Tenant" include male and female, singular and
plural, corporation, partnership, limited liability company (and the officers,
members, partners, employees or agents of any such entities) or individual, as
may fit the particular parties.

      10.   REPAIRS BY LANDLORD. Tenant, by taking possession of the Premises,
shall accept and shall be held to have accepted the Premises as suitable for the
use intended by this Lease. Landlord shall not be required, after possession of
the Premises has been delivered to Tenant, to make any repairs or improvements
to the Premises, except as set forth in this Lease. Except for damage caused by
casualty and condemnation (which shall be governed by Section 28 and 29 below),
and subject to normal wear and tear, Landlord shall maintain in good repair the
exterior walls, roof, common areas, foundation, structural portions and the
central portions of the Building's mechanical, electrical, plumbing and HVAC
systems

<PAGE>

(i.e., only those portions of central distribution, but not the branches which
serve only one tenant's space), provided such repairs are not occasioned by
Tenant, Tenant's invitees or anyone in the employ or control of Tenant.

      11.   REPAIRS BY TENANT. Except as described in Section 10 above, Tenant
shall, at its own cost and expense, maintain the Premises in good repair and in
a neat and clean, first-class condition, including making all necessary repairs
and replacements. Tenant shall further, at its own cost and expense, repair or
restore any damage or injury to all or any part of the Building caused by Tenant
or Tenant's agents, employees, invitees, licensees, visitors or contractors,
including but not limited to any repairs or replacements necessitated by (i) the
construction or installation of improvements to the Premises by or on behalf of
Tenant, (ii) the moving of any Property into or out of the Premises. If Tenant
fails to make such repairs or replacements promptly, Landlord may, at its
option, make the repairs and replacements and the costs of such repair or
replacements shall be charged to Tenant as Additional Rent and shall become due
and payable by Tenant with the monthly installment of Base Rent next due
hereunder.

      12.   ALTERATIONS AND IMPROVEMENTS. Except for minor, decorative
alterations which do not affect the Building structure or systems, are not
visible from outside the Premises and do not cost in excess of $10,000.00 in the
aggregate, Tenant shall not make or allow to be made any alterations, physical
additions or improvements in or to the Premises without first obtaining in
writing Landlord's written consent for such alterations or additions, which
consent may be granted or withheld in the sole, unfettered discretion of
Landlord (if the alterations will affect the Building structure or systems or
will be visible from outside the Premises), but which consent shall not be
unreasonably withheld (if the alterations will not affect the Building structure
or systems and will not be visible from outside the Premises). Upon Landlord's
request, Tenant will furnish Landlord plans and specifications for any proposed
alterations, additions or improvements and shall reimburse Landlord for its
reasonable cost to review such plans. Any alterations, physical additions or
improvements shall at once become the property of Landlord; provided, however,
Landlord, at its option, may require Tenant to remove any alterations, additions
or improvements in order to restore the Premises to the condition existing on
the Commencement Date. All costs of any such alterations, additions or
improvements shall be borne by Tenant. All alterations, additions or
improvements must be made in a good, first-class, workmanlike manner and in a
manner that does not disturb other tenants (i.e., any loud work must be
performed during non-business hours) and Tenant must maintain appropriate
liability and builder's risk insurance throughout the construction. Tenant does
hereby indemnify and hold Landlord harmless from and against all claims for
damages or death of persons or damage or destruction of property arising out of
the performance of any such alterations, additions or improvements made by or on
behalf of Tenant. Under no circumstances shall Landlord be required to pay,
during the Term of this Lease and any extensions or renewals thereof, any ad
valorem or Property tax on such alterations, additions or improvements, Tenant
hereby covenanting to pay all such taxes when they become due. In the event any
alterations, additions, improvements or repairs are to be performed by
contractors or workmen other than Landlord's contractors or workmen, any such
contractors or workmen must first be approved, in writing, by Landlord. Landlord
agrees to assign to Tenant any rights it may have against the contractor of the
Premises with respect to any work performed by said contractor in connection
with improvements made by Landlord at the request of Tenant.

      13.   OPERATING EXPENSES.

            (a)   Tenant agrees to reimburse Landlord throughout the Term, as
Additional Rent hereunder for Tenant's Share (as defined below) of the annual
Operating Expenses (as defined below) in excess of the Operating Expenses for
calendar year 2001 (hereinafter called the "Base Year Amount"). The term
"Tenant's Share" shall mean the percentage determined by dividing the rentable
square footage of the Premises by the rentable square footage of the Building.
If Tenant does not lease the Premises during the entire full calendar year in
which the Term of this Lease commences or ends, Tenant's Share of excess
Operating Expenses for the applicable calendar year shall be appropriately
prorated for the partial year, based on the number of days Tenant has leased the
Premises during that year.

<PAGE>

            (b)   Operating Expenses shall be all those expenses of operating,
servicing, managing, maintaining and repairing the Property, Building, all
parking areas and related common areas (as well as an allocation of certain
Project or Park expenses, as reasonably allocated by Landlord to the Building
and the other buildings in the Project or Park) in a manner deemed by Landlord
reasonable and appropriate and in the best interest of the tenants of the
Building and in a manner consistent with first-class office buildings in
Birmingham, Alabama. Operating Expenses shall include, without limitation, the
following:

                  (1)   All taxes and assessments, whether general or special,
applicable to the Property and the Building, which shall include real and
personal property ad valorem taxes, and any and all reasonable costs and
expenses incurred by Landlord in seeking a reduction of any such taxes and
assessments. However, Tenant shall not be obligated for taxes on the net income
from the operation of the Building, unless there is imposed in the future a tax
on rental income on the Building in lieu of the real Property ad valorem taxes,
in which event such tax shall be deemed an Operating Expense of the Building.

                  (2)   Insurance premiums and deductible amounts, including,
without limitation, for commercial general liability, "all risks" property, rent
loss and other coverages carried by Landlord on the Building and Property.

                  (3)   All utilities, including, without limitation, water,
power, heating, lighting, ventilation, sanitary sewer and air conditioning of
the Building, but not including those utility charges actually paid by Tenant or
other tenants of the Building.

                  (4)   Janitorial and maintenance expenses, including:

                        (i) Janitorial services and janitorial supplies and
other materials used in the operation and maintenance of the Building;

                        (ii) The cost of maintenance and service agreements on
equipment, window cleaning, grounds maintenance, pest control, security, trash
and snow removal, and other similar services or agreements;

                  (5)   Management fees (or a charge equal to fair market
management fees if Landlord provides its own management services) and the market
rental value of a management office;

                  (6)   The costs, including interest, amortized over its useful
life, of any capital improvement made to the Building by or on behalf of
Landlord after the date of this Lease which is required under any governmental
law or regulation (or any judicial interpretation thereof) that was not
applicable to the Building as of the date of this Lease, and of the acquisition
and installation of any device or equipment designed to improve the operating
efficiency of any system within the Building or which is acquired to improve the
safety of the Building, Park or Project.

                  (7)   All services, supplies, repairs, replacements or other
expenses directly and reasonably associated with servicing, maintaining,
managing and operating the Building, including, but not limited to the lobby,
vehicular and pedestrian traffic areas and other common use areas.

                  (8)   Wages and salaries of Landlord's employees (not above
the level of Building manager) engaged in the maintenance, operation, repair and
services of the Building, including taxes, insurance and customary fringe
benefits.

                  (9)   Legal and accounting costs.

                  (10)  Costs to maintain and repair the Building and Property.

<PAGE>

                  (11)  Landscaping and security costs unless Landlord hires a
third party to provide such services pursuant to a service contract and the cost
of that service contract is already included in Operating Expenses as described
above.

                  (12)  The Building's allocated share (as reasonably be
determined by Landlord) of certain expenses which are incurred on a Project-wide
or Park-wide basis including, without limitation, costs in connection with (i)
landscaping, (ii) utility and road repairs, (iii) security, (iv) signage
installation, replacement and repair and (v) taxes or assessments which are not
assessed against a particular building or the parcel on which it is located.

            (c)   Landlord shall, on or before the Commencement Date and on or
before December 20 of each calendar year, provide Tenant a statement of the
estimated monthly installments of Tenant's Share of excess Operating Expenses
increases which will be due for the remainder of the calendar year in which the
Commencement Date occurs or for the upcoming calendar year, as the case may be.
As soon as practicable after December 31 of each calendar year during the Term
of this Lease, Landlord shall furnish to Tenant an itemized statement of the
Operating Expenses within the Building for the calendar year then ended. Upon
reasonable prior written request given not later than thirty (30) days following
the date Landlord's statement is delivered to Tenant, Landlord will provide
Tenant detailed documentation to support the itemized statement. If Tenant does
not notify Landlord of any objection to Landlord's itemized statement within
thirty (30) days of Landlord's delivery thereof, Tenant shall be deemed to have
accepted such statement as true and correct and shall be deemed to have waived
any right to dispute the excess Operating Expenses due pursuant to that
statement.

                        (i) Tenant shall pay to Landlord, together with its
monthly payment of Base Rent as provided in Sections 3 and 4 hereinabove, as
Additional Rent hereunder, the estimated monthly installment of Tenant's Share
of the excess Operating Expenses for the calendar year in question. At the end
of any calendar year if Tenant has paid to Landlord an amount in excess of
Tenant's Share of excess Operating Expenses for such calendar year, Landlord
shall reimburse to Tenant any such excess amount (or shall apply any such excess
amount to any amount then owing to Landlord hereunder, and if none, to the next
due installment or installments of Additional Rent due hereunder, at the option
of Landlord). At the end of any calendar year if Tenant has paid to Landlord
less than Tenant's Share of excess Operating Expenses for such calendar year,
Tenant shall pay to Landlord any such deficiency within thirty (30) days after
Tenant receives the annual statement.

                        (ii) For the calendar year in which this Lease
terminates, and is not extended or renewed, the provisions of this Section shall
apply, but Tenant's Share for such calendar year shall be subject to a pro rata
adjustment based upon the number of days prior to the expiration of the Term of
this Lease. Tenant shall make monthly estimated payments of the prorata portion
of Tenant's Share for such calendar year (in the manner provided above) and when
the actual prorated Tenant's Share for such calendar year is determined Landlord
shall send a statement to Tenant and if such statements reveals that Tenant's
estimated payments for the prorated Tenant's Share for such calendar year
exceeded the actual prorated Tenant's Share for such calendar year, Landlord
shall include a check for that amount along with the statement. If the statement
reveals that Tenant's estimated payments for the prorated Tenant's Share for
such calendar year were less than the actual prorated Tenant's Share for such
calendar year, Tenant shall pay the shortfall to Landlord within thirty (30)
days of the date Tenant receives Landlord's statement.

                        (iii) If the Building is less than ninety-five percent
(95%) occupied throughout any calendar year of the Term, then the actual
Operating Expenses for the calendar year in question shall be increased to the
amount of Operating Expenses which Landlord reasonably determines would have
been incurred during that calendar year if the Building had been fully occupied
throughout such calendar year. If the provisions of this subsection are applied
in any calendar year the Base Year Amount shall likewise be adjusted for the
calendar year on which it is based.

      14.   LANDLORD'S FAILURE TO GIVE POSSESSION. Landlord shall not be liable
for damages to Tenant for failure to deliver possession of the Premises to
Tenant if such failure is due to no fault of Landlord, to the failure of any
construction or remodeling of the Premises by Tenant to be completed or to the
failure of any previous tenant to vacate the Premises. Landlord will use its
best efforts to give possession to Tenant by the scheduled Commencement Date of
the Term. If Landlord's failure to do so is caused by the act of any previous
tenant holding over, Landlord agrees to transfer to Tenant the right to
prosecute in its own name any cause of action which Landlord may have against
such tenant holding over, Tenant to hold for itself any recovery in such action,
except for any amounts due Landlord as Rent hereunder.

      15.   ACCEPTANCE AND WAIVER. Landlord shall not be liable to Tenant, its
agents, employees, guests or invitees (and, if Tenant is a corporation, its
officers, agents, employees, guests or invitees) for any damage caused to any of
them due to the Building or any part or appurtenances thereof being improperly
constructed or being or becoming out of repair, or arising from the leaking of
gas, water, sewer or steam pipes, or from electricity, but Tenant, by moving
into the Premises and taking possession thereof, shall accept, and shall be held
to have accepted the Premises as suitable for the purposes for which the same
are leased, and shall accept and shall be held to have accepted the Building and
every appurtenances thereof, and Tenant by said act waives any and all defects
therein; provided, however, that this Section shall not apply to any damages or
injury caused by or resulting from the negligence or willful misconduct of
Landlord.

      16.   SIGNS. A Building standard suite entry shall be installed on the
door to the Premises or adjacent to the entry to the Premises as part of the
Work and the cost thereof shall be paid out of the Allowance. Otherwise, Tenant
shall not paint or place signs, placards, or other advertisement of any
character upon the windows or inside walls of the Premises except with the
consent of Landlord which consent may be withheld by Landlord in its absolute
discretion, and Tenant shall place no signs upon the outside walls, common areas
or the roof of the Building.

      17.   ADVERTISING. Landlord may advertise the Premises as being "For Rent"
at any time following a default by Tenant which remains uncured and at any time
within one hundred eighty (180) days prior to the expiration, cancellation or
termination of this Lease for any reason and during any such periods may exhibit
the Premises to prospective tenants.

      18.   REMOVAL OF FIXTURES. If Tenant is not in default hereunder, Tenant
may, prior to the expiration of the Term of this Lease, or any extension
thereof, remove any fixtures and equipment which it has placed in the Premises
which can be removed without significant damage to the Premises, provided Tenant
repairs all damages to the Premises caused by such removal.

      19.   ENTERING PREMISES. Landlord may enter the Premises at reasonable
hours provided that Landlord's entry shall not unreasonably interrupt Tenant's
business operations and that prior notice is given when reasonably possible
(and, if in the opinion of Landlord any emergency exists, at any time and
without notice): (a) to make repairs, perform maintenance and provide other
services described in Section 20 below (no prior notice is required to provide
routine services) which Landlord is obligated to make to the Premises or the
Building pursuant to the terms of this Lease or to the other premises within the
Building pursuant to the leases of other tenants; (b) to inspect the Premises to
see that Tenant is complying with all of the terms and conditions of this Lease

electrical, plumbing or HVAC equipment through the areas behind the walls, below
the floors or above the drop ceilings; and (e) to exercise any other right or
perform any other obligation that Landlord has under this Lease. Landlord shall
be allowed to take all material into and upon the Premises that may be required
to make any repairs, improvements and additions, or any alterations, without in
any way being deemed or held guilty of trespass and without constituting a
constructive eviction of Tenant. The Rent reserved herein shall not abate while
said repairs, alterations or additions are being made and Tenant shall not be
entitled to maintain a set-off or counterclaim for damages

<PAGE>

against Landlord by reason of loss from interruption to the business of Tenant
because of the prosecution of any such work. All such repairs, decorations,
additions and improvements shall be done during ordinary business hours, or, if
any such work is at the request of Tenant to be done during any other hours, the
Tenant shall pay all overtime and other extra costs.

      20.   SERVICES.

cost of such added services; charge Tenant for the cost of any additional
equipment or facilities or modifications thereto, necessary to provide the
additional services; and/or to discontinue providing such excess services to
Tenant.

            (c)   Landlord shall not be liable for any damages directly or
indirectly resulting from the interruption in any of the services described
above, nor shall any such interruption entitle Tenant to any abatement of Rent
or any right to terminate this Lease. Landlord shall use all reasonable efforts
to furnish uninterrupted services as required above.

<PAGE>

      21.   INDEMNITIES. Tenant does hereby indemnify and save harmless Landlord
against all claims for damages to persons or property which are caused anywhere
in the Building or on the property caused by the negligence or willful
misconduct of Tenant, its agents or employees or which occur in the Premises (or
arise out of actions taking place in the Premises) unless such damage is caused
by the negligence or willful misconduct of Landlord, its agents, or employees.
Landlord does hereby indemnify and hold Tenant harmless against all claims for
damaged persons or property if caused by the negligence or willful misconduct of
Landlord, its agents or employees. The indemnities set forth hereinabove shall
include the application to pay reasonable expenses incurred by the indemnified
party, including, without limitation, reasonable, actually incurred attorney's
fees. The indemnities contained herein do not override the waivers contained in
Section 22(d) below.

      22.   TENANT'S INSURANCE; WAIVERS.

            (a)   Tenant further covenants and agrees that from and after the
date of delivery of the Premises from Landlord to Tenant, Tenant will carry and
maintain, at its sole cost and expense, the following types of insurance, in the
amounts specified and in the form hereinafter provided for:

                  (i)   Liability Insurance in the Commercial General Liability
form (or reasonable equivalent thereto) covering the Premises and Tenant's use
thereof against claims for personal injury or death, property damage and product
liability occurring upon, in or about the Premises, such insurance to be written
on an occurrence basis (not a claims made basis), to be in combined single
limits amounts not less than $3,000,000 and to have general aggregate limits of
not less than $5,000,000 for each policy year. The insurance coverage required
under this Section 22(a)(i) shall, in addition, extend to any liability of
Tenant arising out of the indemnities provided for in Section 21 and, if
necessary, the policy shall contain a contractual endorsement to that effect.
The general aggregate limits under the Commercial General Liability insurance
policy or policies must apply separately to the Premises and to Tenant's use
thereof (and not to any other location or use of Tenant) and such policy shall
contain an endorsement to that effect. The certificate of insurance evidencing
the Commercial General Liability form of policy shall specify all endorsements
required herein and shall specify on the face thereof that the limits of such
policy applies separately to the Premises.

                  (ii)  Boiler and machinery insurance in adequate amounts on
all fired objects and other fired pressure vessels and systems serving the
Premises (if any); and if the said objects and the damage that may be caused by
them or result from them are not covered by Tenant's extended coverage
insurance, then such insurance shall be in an amount not less than $250,000 and
be issued on a replacement cost basis.

                  (iii) Insurance covering all of the items included in Tenant's
leasehold improvements, heating, ventilating and air conditioning equipment
maintained by Tenant, trade fixtures, merchandise and personal property from
time to time in, on or upon the Premises, and alterations, additions or changes
made by Tenant pursuant to Section 12, in an amount not less than one hundred
percent (100%) of their full replacement value from time to time during the
Term, providing protection against perils included within the standard form of
"all-risks" fire and casualty insurance policy, together with insurance against
sprinkler damage, vandalism and malicious mischief. Any policy proceeds from
such insurance shall be held in trust by Tenant's insurance company for the
repair, construction and restoration or replacement of the property damaged or
destroyed unless this Lease shall cease and terminate under the provisions of
Section 28 of this Lease.

                  (iv)  Workers' Compensation and Employer's Liability insurance
affording statutory coverage and containing statutory limits with the Employer's
Liability portion thereof to have minimum limits of $500,000.00.

<PAGE>

                  (v)   Business Interruption Insurance equal to not less than
fifty percent (50%) of the estimated gross earnings (as defined in the standard
form of business interruption insurance policy) of Tenant at the Premises which
insurance shall be issued on an "all risks" basis (or its equivalent).

            (b)   All policies of the insurance provided for in Section 22(a)
shall be issued in form acceptable to Landlord by insurance companies with a
rating and financial size of not less than A-X in the most current available
"Best's Insurance Reports", and licensed to do business in the state in which
Landlord's Building is located. Each and every such policy:

                  (i)   shall name Landlord as an additional insured (as well as
any mortgagee of Landlord and any other party reasonably designated by Landlord)
and the coverage in (ii) and (iii) shall also name Landlord as loss payee.

                  (ii)  shall (and a certificate thereof shall be delivered to
Landlord at or prior to the execution of the Lease) be delivered to each of
Landlord and any such other parties in interest within thirty (30) days after
delivery of possession of the Premises to Tenant and thereafter within thirty
(30) days prior to the expiration of each such policy, and, as often as any such
policy shall expire or terminate. Renewal or additional policies shall be
procured and maintained by Tenant in like manner and to like extent;

                  (iii) shall contain a provision that the insurer will give to
Landlord and such other parties in interest at least thirty (30) days notice in
writing in advance of any material change, cancellation, termination or lapse,
or the effective date of any reduction in the amounts of insurance; and

                  (iv)  shall be written as a primary policy which does not
contribute to and is not in excess of coverage which Landlord may carry.

            (c)   Any insurance provided for in Section 22(a) may be maintained
by means of a policy or policies of blanket insurance, covering additional items
or locations or insureds, provided, however, that:

                  (i)   Landlord and any other parties in interest from time to
time designated by Landlord to Tenant shall be named as an additional insured
thereunder as its interest may appear;

                  (ii)  the coverage afforded Landlord and any such other
parties in interest will not be reduced or diminished by reason of the use of
such blanket policy of insurance;

                  (iii) any such policy or policies [except any covering the
risks referred to in Section 22(a)] shall specify therein (or Tenant shall
furnish Landlord with a written statement from the insurers under such policy
specifying) the amount of the total insurance allocated to the Tenant's
improvements and property more specifically detailed in Section 22(a); and

                  (iv)  the requirements set forth in this Section 22 are
otherwise satisfied.

            (d)   Notwithstanding anything to the contrary set forth
hereinabove, Landlord and Tenant do hereby waive any and all claims against one
another for damage to or destruction of real or personal property to the extent
such damage or destruction can be covered by "all risks" property insurance of
the type described in Section 22(a)(iii) above. Each party shall also be
responsible for the payment of any deductible amounts required to be paid under
the applicable "all risks" fire and casualty insurance carried by the party
whose property is damaged. These waivers shall apply if the damage would have
been covered by a customary "all risks" insurance policy, even if the party
fails to obtain such coverage. The intent of this provision is that each party
shall look solely to its insurance with respect to property damage or
destruction which can be covered by "all risks" insurance of the type described
in Section 22(a)(iii). To

<PAGE>

further effectuate the provisions of this Section 22(d), Landlord and Tenant
both agree to provide copies of this Lease (and in particular, these waivers) to
their respective insurance carriers and to require such insurance carriers to
waive all rights of subrogation against the other party with respect to property
damage covered by the applicable "all risks" fire and casualty insurance policy.

      23.   GOVERNMENTAL REQUIREMENTS. Tenant shall, at its own expense,
promptly comply with all requirements of any legally constituted governmental or
public authority made necessary by reason of Tenant's occupancy of the Premises,
including, without limitation, the Americans with Disabilities Act.

      24.   ABANDONMENT OF PREMISES. Tenant agrees not to abandon or vacate the
Premises during the Term of this Lease. If Tenant does abandon or vacate the
Premises for more than ninety (90) days, Landlord may terminate this Lease, by
written notice to Tenant at any time prior to Tenant reoccupying the Premises,
but such termination shall not entitle Landlord to pursue any other remedies
unless an uncured Event of Default then exists, in which case Landlord may
pursue any and all remedies provided by this Lease, at law or in equity.

      25.   ASSIGNMENT AND SUBLETTING. Tenant may not, without the prior written
consent of Landlord, which consent may not be unreasonably withheld by Landlord,
assign this Lease or any interest hereunder, or sublet the Premises or any part
thereof, or permit the use of the Premises by any party other than Tenant.
Landlord will be deemed reasonable in withholding its consent to any such
request based on: (i) the poor business reputation of the proposed assignee,
sublessee or transferee; (ii) the poor financial condition of the proposed
assignee, sublessee or transferee; (iii) the fact that the use of the proposed
assignee, sublessee or transferee is not in keeping with the nature of the
Building or may affect the marketability of the Building; (iv) the fact that
proposed assignee, sublessee or transferee is an existing tenant of the Project,
or is a prospective tenant with respect to space in the Project; or (v) the fact
that the use contemplated by the proposed assignee, sublessee or transferee
would violate an exclusive granted by Landlord to another tenant of the Project
or otherwise. In the event that Tenant is a corporation or entity other than an
individual, any transfer of a majority or controlling interest in Tenant
(whether by stock transfer, merger, operation of law or otherwise) shall be
considered an assignment for purposes of this paragraph and shall require
Landlord's prior written consent. Consent to one assignment or sublease shall
not destroy or waive this provision, and all later assignments and subleases
shall likewise be made only upon the prior written consent of Landlord.
Subtenants or assignees shall become liable to Landlord for all obligations of
Tenant hereunder, without relieving Tenant's liability hereunder and, in the
event of any default by Tenant under this Lease, Landlord may, at its option,
but without any obligation to do so, elect to treat such sublease or assignment
as a direct Lease with Landlord and collect rent directly from the subtenant. In
addition, upon any request by Tenant for Landlord's consent to an assignment or
sublease, Landlord may elect to terminate this Lease and recapture all of the
Premises (in the event of an assignment request) or the applicable portion of
the Premises (in the event of a subleasing request); provided, however, if
Landlord notifies Tenant that Landlord elects to exercise this recapture right,
Tenant may, within five (5) business days of its receipt of Landlord's notice,
notify Landlord that Tenant withdraws its request to sublease or assign, in
which case Tenant shall continue to lease all of the Premises, subject to the
terms of this Lease and Landlord's recapture notice shall be null and void. If
Tenant desires to assign or sublease, Tenant must provide written notice to
Landlord describing the proposed transaction in detail and providing all
documentation (including detailed financial information for the proposed
assignee or subtenant) reasonably necessary to let Landlord evaluate the
proposed transaction. Landlord shall notify Tenant within twenty (20) days of
its receipt of such notice whether Landlord elects to exercise its recapture
right and, if not, whether Landlord consents to the requested assignment or
sublease. If Landlord fails to respond within such twenty (20) day period,
Landlord will be deemed not to have elected to recapture and not to have
consented to the assignment or sublease. If Landlord does consent to any
assignment or sublease request and the assignee or subtenant pays to Tenant an
amount in excess of the Rent due under this Lease (after deducting Tenant's
reasonable, actual expenses in obtaining such assignment or sublease, amortized
in equal monthly installments over the then remainder of the Term), Tenant shall
pay 75% of such excess to Landlord as and when the monthly payments are received
by Tenant.

<PAGE>

      26.   DEFAULT. If Tenant shall default in the payment of Rent herein
reserved when due and fails to cure such default within five (5) business days
after written notice of such default is given to Tenant by Landlord; or if
Tenant shall be in default in performing any of the terms or provisions of this
Lease other than the provisions requiring the payment of Rent, and fails to cure
such default within thirty (30) days after written notice of such default is
given to Tenant by Landlord [or, if such default cannot be cured within thirty
(30) days, Tenant shall not be in default if Tenant promptly commences and
diligently proceeds the cure to completion as soon as possible and in all events
within ninety (90) days]; or if Tenant is adjudicated a bankrupt; or if a
permanent receiver is appointed for Tenant's Property and such receiver is not
removed within sixty (60) days after written notice from Landlord to Tenant to
obtain such removal; or if, whether voluntarily or involuntarily, Tenant takes
advantage of any debtor relief proceedings under any present or future law,
whereby the Rent or any part thereof, is, or is proposed to be, reduced or
payment thereof deferred; or if Tenant's effects should be levied upon or
attached and such levy or attachment is not satisfied or dissolved within thirty
(30) days after written notice from Landlord to Tenant to obtain satisfaction
thereof; or, if Tenant is an individual, in the event of the death of the
individual and the failure of the executor, administrator or personal
representative of the estate of the deceased individual to have assigned the
Lease within three (3) months after the death to an assignee approved by
Landlord; then, and in any of said events, Landlord, at its option, may exercise
any or all of the remedies set forth in Section 27 below.

      27.   REMEDIES. Upon the occurrence of any default set forth in Section 26
above which is not cured by Tenant within the applicable cure period provided
therein, if any, Landlord may exercise all or any of the following remedies:

            (a)   terminate this Lease by giving Tenant written notice of
termination, in which event this Lease shall terminate on the date specified in
such notice and all rights of Tenant under this Lease shall expire and terminate
as of such date, Tenant shall remain liable for all obligations under this Lease
up to the date of such termination and Tenant shall surrender the Premises to
Landlord on the date specified in such notice, and if Tenant fails to so
surrender, Landlord shall have the right, without notice, to enter upon and take
possession of the Premises and to expel and remove Tenant and its effects
without being liable for prosecution or any claim of damages therefor;

            (b)   terminate this Lease as provided in the immediately preceding
subsection and recover from Tenant all damages Landlord may incur by reason of
Tenant's default, including without limitation, the then present value of (i)
the total Rent which would have been payable hereunder by Tenant for the period
beginning with the day following the date of such termination and ending with
the Expiration Date of the term as originally scheduled hereunder, minus (ii)
the aggregate reasonable rental value of the Premises for the same period (as
determined by a real estate broker licensed in the State of Alabama, who has at
least ten (10) years experience, immediately prior to the date in question
evaluating commercial office space, taking into account all relevant factors
including, without limitation, the length of the remaining Term, the then
current market conditions in the general area, the likelihood of reletting for a
period equal to the remainder of the Term, net effective rates then being
obtained by landlords for similar type space in similar buildings in the general
area, vacancy levels in the general area, current levels of new construction in
the general area and how that would affect vacancy and rental rates during the
period equal to the remainder of the Term and inflation), plus (iii) the costs
of recovering the Premises, and all other expenses incurred by Landlord due to
Tenant's default, including, without limitation, reasonable attorneys' fees,
plus (iv) the unpaid Rent earned as of the date of termination, plus interest,
all of which sum shall be immediately due and payable by Tenant to Landlord;

            (c)   without terminating this Lease, and without notice to Tenant,
Landlord may in its own name, but as agent for Tenant enter into and take
possession of the Premises and re-let the Premises, or a portion thereof, as
agent of Tenant, upon any terms and conditions as Landlord may deem necessary or
desirable (Landlord shall have no obligation to attempt to re-let the Premises
or any part thereof. Upon any such re-letting, all rentals received by Landlord
from such re-letting shall be applied first to the costs incurred by Landlord in
accomplishing any such re-letting, and thereafter shall be applied

<PAGE>

to the Rent owed by Tenant to Landlord during the remainder of the term of this
Lease and Tenant shall pay any deficiency between the remaining Rent due
hereunder and the amount received by such re-letting as and when due hereunder;

            (d)   allow the Premises to remain unoccupied and collect Rent from
Tenant as it becomes due; or

            (e)   pursue such other remedies as are available at law or in
equity.

      28.   DESTRUCTION OR DAMAGE.

            (a)   If the Building or the Premises are totally destroyed by
storm, fire, earthquake, or other casualty, or damaged to the extent that, in
Landlord's reasonable opinion the damage cannot be restored within one hundred
eighty (180) days of the date Landlord provides Tenant written notice of
Landlord's reasonable estimate of the time necessary to restore the damage, or
if the damage is not covered by standard "all risks" property insurance, or if
the Landlord's lender requires that the insurance proceeds be applied to its
loan, Landlord shall have the right to terminate this Lease effective as of the
date of such destruction or damage by written notice to Tenant on or before
thirty (30) days following Landlord's notice described in the next sentence and
Rent shall be accounted for as between Landlord and Tenant as of that date.
Landlord shall provide Tenant with notice within sixty (60) days following the
date of the damage of the estimated time needed to restore, whether the loss is
covered by Landlord's insurance coverage and whether or not Landlord's lender
requires the insurance proceeds be applied to its loan.

            (b)   If the Premises are damaged by any such casualty or casualties
but Landlord is not entitled to or does not terminate this Lease as provided in
subparagraph (a) above, this Lease shall remain in full force and effect,
Landlord shall notify Tenant in writing within sixty (60) days of the date of
the damage that the damage will be restored (and will include Landlord's good
faith estimate of the date the restoration will be complete), in which case Rent
shall abate as to any portion of the Premises which is not usable, and Landlord
shall restore the Premises to substantially the same condition as before the
damage occurred as soon as practicable, whereupon full Rent shall recommence.

      29.   EMINENT DOMAIN. If the whole of the Building or Premises, or such
portion thereof as will make the Building or Premises unusable in the reasonable
judgment of Landlord for their intended purposes, is condemned or taken by any
legally constituted authority for any public use or purpose, then in either of
said events, Landlord may terminate this Lease by written notice to Tenant and
the Term hereby granted shall cease from that time when possession thereof is
taken by the condemning authorities, and Rent shall be accounted for as between
Landlord and Tenant as of that date. If a portion of the Building or Premises is
so taken, but not such amount as will make the Premises unusable in the
reasonable judgment of Landlord for the purposes herein leased, or if Landlord
elects not to terminate this Lease, this Lease shall continue in full force and
effect and the Rent shall be reduced prorata in proportion to the amount of the
Premises so taken. Tenant shall have no right or claim to any part of any award
made to or received by Landlord for such condemnation or taking, and all awards
for such condemnation or taking shall be made solely to Landlord. Tenant shall,
however, have the right to pursue any separate award that does not reduce the
award to which Landlord is entitled.

      30.   SERVICE OF NOTICE. Except as otherwise provided by law, Tenant
hereby appoints as its agent to receive the service of all dispossessory or
distraint proceedings and notices thereunder, the person in charge of or
occupying the Premises at the time of such proceeding or notice; and if no
person be in charge or occupying the Premises, then such service may be made by
attaching the same to the front entrance of the Premises.

      31.   MORTGAGEE'S RIGHTS.

<PAGE>

            (a)   Tenant agrees that this Lease shall be subject and subordinate
(i) to any mortgage, deed to secure debt or other security interest now
encumbering the Property and to all advances which may be hereafter made, to the
full extent of all debts and charges secured thereby and to all renewals or
extensions of any part thereof, and to any mortgage, deed to secure debt or
other security interest which any owner of the Property may hereafter, at any
time, elect to place on the Property; (ii) to any assignment of Landlord's
interest in the leases and rents from the Building or Property which includes
the Lease which now exists or which any owner of the Property may hereafter, at
any time, elect to place on the Property; and (iii) to any Uniform Commercial
Code Financing Statement covering the personal property rights of Landlord or
any owner of the Property which now exists or any owner of the Property may
hereafter, at any time, elect to place on the foregoing personal property (all
of the foregoing instruments set forth in (i), (ii) and (iii) above being
hereafter collectively referred to as "Security Documents"). Tenant agrees upon
request of the holder of any Security Documents ("Holder") to hereafter execute
any documents which the counsel for Landlord or Holder may deem necessary to
evidence the subordination of the Lease to the Security Documents. If Tenant
fails to execute any such requested documents, Landlord or Holder is hereby
empowered to execute such documents in the name of Tenant evidencing such
subordination, as the act and deed of Tenant, and this authority is hereby
declared to be coupled with an interest and not revocable.

            (b)   In the event of a foreclosure pursuant to any Security
Documents, Tenant shall at the election of the Landlord, thereafter remain bound
pursuant to the terms of this Lease as if a new and identical Lease between the
purchaser at such foreclosure ("Purchaser"), as landlord, and Tenant, as tenant,
had been entered into for the remainder of the Term hereof and Tenant shall
attorn to the Purchaser upon such foreclosure sale and shall recognize such
Purchaser as the Landlord under the Lease. Such attornment shall be effective
and self-operative without the execution of any further instrument on the part
of any of the parties hereto. Tenant agrees, however, to execute and deliver at
any time and from time to time, upon the request of Landlord or of Holder, any
instrument or certificate that may be necessary or appropriate in any such
foreclosure proceeding or otherwise to evidence such attornment.

            (c)   If the Holder of any Security Document or the Purchaser upon
the foreclosure of any of the Security Documents shall succeed to the interest
of Landlord under the Lease, such Holder or Purchaser shall have the same
remedies, by entry, action or otherwise for the non-performance of any agreement
contained in the Lease, for the recovery of Rent or for any other default or
event of default hereunder that Landlord had or would have had if any such
Holder or Purchaser had not succeeded to the interest of Landlord. Any such
Holder or Purchaser which succeeds to the interest of Landlord hereunder, shall
not be (a) liable for any act or omission of any prior Landlord (including
Landlord); or (b) subject to any offsets or defenses which Tenant might have
against any prior Landlord (including Landlord); or (c) bound by any Rent which
Tenant might have paid for more than the current month to any prior Landlord
(including Landlord); or (d) bound by any amendment or modification of the Lease
made without its consent.

            (d)   Tenant hereby acknowledges that if the interest of Landlord
hereunder is covered by an assignment of Landlord's interest in Lease, Tenant
shall pay all Rent due and payable under the Lease directly to the Holder of the
assignment of Landlord's interest in Lease upon notification of the exercise of
the rights thereunder by the Holder thereof.

            (e)   Notwithstanding anything to the contrary set forth in this
Section 31, the Holder of any Security Documents shall have the right, at any
time, to elect to make this Lease superior and prior to its Security Document.
No documentation, other than written notice to Tenant, shall be required to
evidence that the Lease has been made superior and prior to such Security
Documents, but Tenant hereby agrees to execute any documents reasonably
requested by Landlord or Holder to acknowledge that the Lease has been made
superior and prior to the Security Documents.

      32.   TENANT'S ESTOPPEL. Tenant shall, from time to time, upon not less
than ten (10) days prior written request by Landlord, execute, acknowledge and
deliver to Landlord a written statement

<PAGE>

certifying that this Lease is unmodified and in full force and effect (or, if
there have been modifications, that the same is in full force and effect as
modified and stating the modifications), the dates to which the Rent has been
paid, that Tenant is not in default hereunder and has no offsets or defenses
against Landlord under this Lease, and whether or not to the best of Tenant's
knowledge Landlord is in default hereunder (and if so, specifying the nature of
the default), it being intended that any such statement delivered pursuant to
this paragraph may be relied upon by a prospective purchaser of Landlord's
interest or by a mortgagee of Landlord's interest or assignee of any security
deed upon Landlord's interest in the Premises.

      33.   ATTORNEY'S FEES AND HOMESTEAD. If Landlord exercises any of the
remedies provided to Landlord under this Lease as a result of Tenant's failure
to comply with its obligations, or if Landlord brings any action to enforce its
rights under this Lease, Tenant shall be obligated to reimburse Landlord, on
demand, for all costs and expenses, including reasonable attorneys' fees and
court costs, incurred in connection therewith. Tenant waives all homestead
rights and exemptions which he may have under any law against any obligations
owing under this Lease and Tenant hereby assigns to Landlord his homestead and
exemption.

      34.   PARKING. No rights to specific parking spaces are granted under this
Lease; however, subject to Landlord's rights pursuant to the remainder of this
Section 34, Tenant shall be entitled to use up to three and one half (3.5)
spaces per each 1,000 rentable square feet of space in the initial Premises in
the parking facilities located on the Property. All parking spaces provided to
Tenant shall be unreserved and are to be used by Tenant, its employees and
invitees in common with the other tenants of the Building and their employees
and invitees. Landlord reserves the right to build improvements upon, reduce the
size of, relocate, reconfigure, eliminate, and/or make alterations or additions
to such parking facilities at any time. The use of the parking spaces is
provided by Landlord to Tenant without additional charge.

      35.   STORAGE. If Landlord makes available to Tenant any storage space
outside the Premises, anything stored therein shall be wholly at the risk of
Tenant, and Landlord shall have no responsibility or liability for the items
stored therein.

      36.   WASTE DISPOSAL.

            (a)   All normal trash and waste (i.e., waste that does not require
special handling pursuant to subparagraph (b) below) shall be disposed of
through the janitorial service.

            (b)   Tenant shall be responsible for the removal and disposal of
any waste deemed by any governmental authority having jurisdiction over the
matter to be hazardous or infectious waste or waste requiring special handling,
such removal and disposal to be in accordance with any and all applicable
governmental rules, regulations, codes, orders or requirements. Tenant agrees to
separate and mark appropriately all waste to be removed and disposed of through
the janitorial service pursuant to (a) above and hazardous, infectious or
special waste to be removed and disposed of by Tenant pursuant to this
subparagraph (b). Tenant hereby indemnifies and holds harmless Landlord from and
against any loss, claims, demands, damage or injury Landlord may suffer or
sustain as a result of Tenant's failure to comply with the provisions of this
subparagraph (b).

      37.   SURRENDER OF PREMISES. Whenever under the terms hereof Landlord is
entitled to possession of the Premises, Tenant at once shall surrender the
Premises and the keys thereto to Landlord in the same condition as on the
Commencement Date hereof, natural wear and tear only excepted, and Tenant shall
remove all of its personalty therefrom and shall, if directed to do so by
Landlord, remove all improvements and restore the Premises to its original
condition prior to the construction of any improvements which have been made
therein by or on behalf of Tenant, including any improvements made prior to the
Commencement Date. Landlord may forthwith re-enter the Premises and repossess
itself thereof and remove all persons and effects therefrom, using such force as
may be necessary without being guilty of forcible entry, detainer, trespass or
other tort. Tenant's obligation to observe or perform these covenants shall
survive the expiration or other termination of the Term of this Lease. If the
last day of the

<PAGE>

Term of this Lease or any renewal falls on Sunday or a legal holiday, this Lease
shall expire on the business day immediately preceding.

      38.   CLEANING PREMISES. Upon vacating the Premises, Tenant agrees to
return the Premises to Landlord broom clean and in the same condition when
Tenant's possession commenced, natural wear and tear excepted.

      39.   NO ESTATE IN LAND. This contract shall create the relationship of
landlord and tenant between Landlord and Tenant; no estate shall pass out of
Landlord; Tenant has only a usufruct, not subject to levy or sale, and not
assignable by Tenant except with Landlord's consent.

      40.   CUMULATIVE RIGHTS. All rights, powers and privileges conferred
hereunder upon the parties hereto shall be cumulative but not restrictive to
those given by law.

      41.   PARAGRAPH TITLES; SEVERABILITY. The paragraph titles used herein are
not to be considered a substantive part of this Lease, but merely descriptive
aids to identify the paragraph to which they refer. Use of the masculine gender
includes the feminine and neuter, and vice versa, where necessary to impart
contextual continuity. If any paragraph or provision herein is held invalid by a
court of competent jurisdiction, all other paragraphs or severable provisions of
this Lease shall not be affected thereby, but shall remain in full force and
effect.

      42.   DAMAGE OR THEFT OF PERSONAL PROPERTY. All personal property brought
into the Premises shall be at the risk of the Tenant only and Landlord shall not
be liable for theft thereof or any damage thereto occasioned by any acts of
co-tenants, or other occupants of the Building, or any other person, except,
with respect to damage to the Premises, as may be occasioned by the negligent or
willful act of the Landlord, its employees and agents.

      43.   HOLDING OVER. In the event Tenant remains in possession of the
Premises after the expiration of the Term hereof, or of any renewal term, with
Landlord's written consent, Tenant shall be a tenant at will and such tenancy
shall be subject to all the provisions hereof, except that the monthly rental
shall be at the higher of double the monthly Base Rent payable hereunder upon
such expiration of the Term hereof, or of any renewal term, or double the then
current fair market rental value of the Premises as the same would be adjusted
pursuant to the provisions of Section 3 hereof. In the event Tenant remains in
possession of the Premises after the expiration of the Term hereof, or any
renewal term, without Landlord's written consent, Tenant shall be a tenant at
sufferance and may be evicted by Landlord without any notice, but Tenant shall
be obligated to pay rent for such period that Tenant holds over without written
consent at the same rate provided in the previous sentence and shall also be
liable for any and all other damages Landlord suffers as a result of such
holdover including, without limitation, the loss of a prospective tenant for
such space. There shall be no renewal of this Lease by operation of law or
otherwise. Nothing in this Section shall be construed as a consent by Landlord
for any holding over by Tenant after the expiration of the Term hereof, or any
renewal term.

      44.   NOT USED.

      45.   BUILDING ALLOWANCE AND TENANT FINISHES.

            (a)   Landlord will provide to Tenant an allowance ("Allowance") of
$14.55 per rentable square foot contained within the Premises to be applied to
the cost of the Work described in Exhibit "B". Tenant and Landlord agree that
all costs of the Work in excess of such Allowance shall be paid in accordance
with the Work Letter. Should Tenant fail to pay for such excess costs when due
as herein provided, such amount due shall accrue interest at the rate of one and
one-half (1-1/2%) percent per month or fraction thereof from the date such
payment is due until paid (Annual Percentage Rate - 18%) and the failure to pay
such amount when due shall be a default, subject to the provisions of Section
26.

<PAGE>

            (b)   The Work Letter attached hereto as Exhibit "B" is hereby made
a part of this Lease, and its provisions shall control in the event of a
conflict with the provisions contained in this Lease.

      46.   RULES AND REGULATIONS. The rules and regulations in regard to the
Building, annexed hereto, and all reasonable rules and regulations which
Landlord may hereafter, from time to time, adopt and promulgate for the
government and management of said Building, are hereby made a part of this Lease
and shall, during the said term, be observed and performed by Tenant, his
agents, employees and invitees.

      47.   QUIET ENJOYMENT. Tenant, upon payment in full of the required Rent
and full performance of the terms, conditions, covenants and agreements
contained in this Lease, shall peaceably and quietly have, hold and enjoy the
Premises during the term hereof. Landlord shall not be responsible for the acts
or omissions of any other tenant, Tenant or third party that may interfere with
Tenant's use and enjoyment of the Premises.

      48.   ENTIRE AGREEMENT. This Lease contains the entire agreement of the
parties and no representations, inducements, promises or agreements, oral or
otherwise, between the parties not embodied herein shall be of any force or
effect.

      49.   LIMITATION OF LIABILITY. Landlord's obligations and liability with
respect to this Lease shall be limited solely to Landlord's interest in the
Building, as such interest is constituted from time to time, and neither
Landlord nor any partner of Landlord, or any officer, director, shareholder, or
partner of any partner of Landlord, shall have any personal liability whatsoever
with respect to this Lease.

      50.   SUBMISSION OF AGREEMENT. Submission of this Lease to Tenant for
signature does not constitute a reservation of space or an option to acquire a
right of entry. This Lease is not binding or effective until execution by and
delivery to both Landlord and Tenant.

      51.   AUTHORITY. If Tenant executes this Lease as a corporation, limited
partnership, limited liability company or any other type of entity, each of the
persons executing this Lease on behalf of Tenant does hereby personally
represent and warrant that Tenant is a duly organized and validly existing
corporation, limited partnership, limited liability company or other type of
entity, that Tenant is qualified to do business in the State of Alabama, that
Tenant has full right, power and authority to enter into this Lease, and that
each person signing on behalf of Tenant is authorized to do so. In the event any
such representation and warranty is false, all persons who execute this Lease
shall be individually, jointly and severally, liable as Tenant. Upon Landlord's
request, Tenant shall provide Landlord with evidence reasonably satisfactory to
Landlord confirming the foregoing representations and warranties.

      52.   NOT USED.

broker licensed in the State of Alabama, has acted as agent for Landlord in this
transaction and is to be paid a commission by Landlord pursuant to a separate
agreement. Hazelrig Realty Company, a real estate broker licensed in the State
of Alabama, has acted as agent for Tenant in this transaction and is to be paid
a commission by Landlord pursuant to a separate agreement. Landlord represents
that it has dealt with no other broker other than the broker(s) identified
herein. Landlord agrees that, if any other broker makes a claim for a commission
based upon the actions of Landlord, Landlord shall indemnify, defend and hold
Tenant harmless from any such claim. Tenant represents that it has dealt with no
broker other than the broker(s) identified herein. Tenant agrees that, if any
other broker makes a claim for a commission based upon the actions of Tenant,
Tenant shall indemnify, defend and hold Landlord harmless from any such claim.
Tenant will cause its broker to execute a customary lien waiver, adequate under
Alabama law, to extinguish any lien claims such broker may have in connection
with this Lease.

either party under this Lease shall be in writing and must be given only by

delivery or by nationally recognized overnight courier service at the addresses

the notice is actually received, but refusal to accept delivery or inability to
accomplish delivery because the party can no longer be found at the then current

                                   EXHIBIT "A"

                                    PROPERTY

Lot 1, according to the Map and Survey of Meadow Brook Corporate Park South,
Phase I, recorded in Map Book 11, Page 72 in the Office of the Judge of Probate
of Shelby County, Alabama.

<PAGE>

                                   EXHIBIT "B"
                                 (WORK LETTER)

In consideration of the execution of the Lease and the mutual covenants and
conditions hereinafter contained, Landlord and Tenant agree as follows:

1. Tenant shall accept the Premises "AS-IS, WHERE IS, AND WITH ALL FAULTS".
Except as specifically set forth in the Lease and in this Work Letter, Landlord
is not obligated to deliver any base building improvements, tenant improvements
or tenant improvement allowances. Tenant has inspected the Premises and is fully
aware of its condition.

2. The Premises shall be constructed (the "Work") in accordance with the plans
attached hereto as Exhibit B-l and by this reference made a part hereof (the
"Plans"). If necessary and required by Landlord, further plans or construction
drawings will be prepared and will be deemed to be part of the Plans. The Plans
(and any modifications thereto and any further plans or construction drawings as
aforesaid) shall comply with all governmental standards, regulations and
requirements and shall be subject to Landlord's approval (which approval shall
not be unreasonably withheld).

3.

      a. Using the contractor selected by Landlord (the "Designated
      Contractor"), Landlord shall diligently prosecute the Work to substantial
      completion. "Substantial Completion" shall mean that the Work is
      sufficiently complete so as to allow Tenant to occupy the Premises for the
      use and purposes intended without unreasonable disturbance or interruption
      as reasonably determined by the Designated Contractor, provided that
      Landlord and the Designated Contractor shall be allowed to enter upon the
      Premises at any reasonable times following Substantial Completion as
      necessary to complete any unfinished details and the punch list, and such
      entry shall not constitute an actual or constructive eviction of Tenant,
      in whole or in part, nor shall it entitle Tenant to any abatement or
      diminution of rentals or relieve Tenant from any obligation under the
      Lease. If Tenant desires any changes in the Work after the date hereof,
      Tenant shall be required to sign such change orders as requested by
      Landlord or the Designated Contractor to evidence any such change desired
      by Tenant, prior to the commencement of Work incorporating the relevant
      change order, and may, upon request of Landlord, be required to deliver to
      Landlord evidence of financing or financial capability of Tenant
      sufficient to cover the excess cost, if any, resulting from such change
      order. The additional cost of any such change orders shall be considered a
      cost of the Work. Landlord shall use commercially reasonable efforts to
      Substantially Complete the Work by January 31, 2002. Notwithstanding
      anything contained herein to the contrary, in the event Landlord is unable
      to Substantially Complete the Work by January 31, 2002, the Commencement
      Date, and all obligations under this Lease, shall nevertheless commence as
      of January 1, 2002, with Landlord achieving Substantial Completion as soon
      as possible thereafter, provided that Landlord and the Designated
      Contractor shall be allowed to enter upon the Premises at any reasonable
      times following the Commencement Date as necessary to achieve Substantial
      Completion, and such entry shall not constitute an actual or constructive
      eviction of Tenant, in whole or in part, nor shall it entitle Tenant to
      any abatement or diminution of rentals or relieve Tenant from any
      obligation under the Lease

      b. In the event Tenant, utilizing its own limited service contractors and
      vendors, will undertake certain limited portions of the improvements to
      the Premises, such as relocation, installation of cabling, systems
      furniture and related items, Tenant shall use licensed contractors,
      approved by Landlord, such approval not to be unreasonably withheld.
      Tenant shall advise its contractors and vendors that no interest of the
      Landlord in the Premises, the Building or the Project shall be subject to
      liens to secure payment of any amount due such contractors or vendors.
      Tenant shall also be responsible to ensure that such limited service
      contractors and vendors do not impede the Designated Contractor in
      performance of the Work. Landlord shall not be liable in

<PAGE>

      any way for any injury, loss, damage or delay which may be caused by or
      arise from Tenant or such limited service contractors or vendors. Such
      limited service contractors and vendors shall be obligated to observe
      Landlord's Construction Rules and Regulations for the Buildings, as such
      may be adopted and amended from time to time.

      c. Tenant's limited service contractors and vendors shall be responsible
      for the removal of trash and debris resulting from the performance of
      their work, and such trash and debris removal shall be undertaken at such
      time and in such manner as designated by Landlord.

4.

      a. Prior to funding of the Allowance by Landlord hereunder, Tenant shall
      fund or cause to be funded (as "Tenant's Contribution") the amount by
      which the cost of the Work, including space planning, the Plans, design,
      construction administration, engineering, the build out costs and all
      other costs arising pursuant to this Work Letter, exceeds the Allowance.
      Tenant's Contribution shall be paid upon Substantial Completion of the
      Work.

      b. Provided the Lease is in full force and effect and no default beyond
      the expiration of any applicable notice and cure periods exists (each a
      "Failed Condition"), utilizing the Allowance and Tenant's Contribution, if
      any, Landlord will pay the Designated Contractor in periodic payments as
      construction progresses according to the contract between Designated
      Contractor and Landlord. In the event the cost of the Work as aforesaid is
      less than the Allowance, Landlord shall retain any balance, with Tenant
      hereby releasing any rights or claims thereto. In the event of a Failed
      Condition, all costs associated with the Work and this Work Letter shall
      be payable by Tenant upon demand therefor, together with all applicable
      late charges and interest applicable to the nonpayment of Rent hereunder.

5.    Upon completion of the connection of Tenant's HVAC system to the
      Building's HVAC systems, as part of the Work, Tenant shall be responsible
      for the cost to test and balance such system by Landlord's designated
      testing and balancing engineer for the Building.

6.    Landlord's agent may attend any and all design and preconstruction
      meetings with Tenant as Landlord shall deem necessary to inform the
      various parties of the minimum requirements for design and construction,
      to assure compliance with the terms of this Work Letter, to coordinate
      construction of the Premises or for any other reason deemed necessary by
      Landlord. Landlord shall further have the right to enter onto the Premises
      during construction thereof at any time and from time to time to perform
      its construction administration services as defined in this Work Letter.

7.    Any approval by Landlord of, or consent by Landlord to, any plans,
      specifications or other items to be submitted to and/or reviewed by
      Landlord pursuant to this Lease shall be deemed to be strictly limited to
      an acknowledgment of approval or consent by Landlord thereto, and such
      approval or consent shall not constitute the assumption by Landlord of any
      responsibility for the accuracy, sufficiency or feasibility of any plans,
      specifications or other such items and shall not imply any acknowledgment,
      representation or warranty by Landlord that the design is safe, feasible,
      structurally sound or will comply with any legal or governmental
      requirements, and Tenant shall be responsible for all of the same.
      Furthermore, neither Landlord's approval of the Designated Contractor, nor
      Landlord's assistance in coordinating the Work, shall impose upon Landlord
      any liability for defects in materials or workmanship in connection with
      the Work, and Tenant shall look solely to the Designated Contractor to
      correct or remedy any such defects.

8.
      a. Tenant shall be responsible for any delay in Substantial Completion
      resulting from any of the following causes:

<PAGE>

            1. Tenant's failure to comply with or to respond to time periods
            specified in this Work Letter; or

            2. Tenant's failure to pay any portion of Tenant's Contribution when
            due; or

            3. Tenant's specification of materials or finishes or special
            installations which cannot be delivered or completed within
            Landlord's construction schedule (subject to Landlord's obligation
            to give Tenant notice of same); or

            4. Any change in the Plans following the date hereof caused by
            Tenant, even though Landlord may approve such change; or

            5. The performance of or failure to perform any special work or
            installation by any person or firm employed by Tenant to do any work
            on the Premises; or

            6. Any other delay in Substantial Completion directly attributable
            to the acts or omissions of Tenant, its employees, agents,
            contractors or vendors.

      b.    In the event that any delay caused by Tenant results in or
            contributes to a delay in Substantial Completion, then the date of
            Substantial Completion shall be deemed to have occurred, and
            Tenant's obligations as defined in the Lease shall commence, as of
            the date Landlord would have otherwise achieved Substantial
            Completion but for Tenant's delay.<PAGE>

                                                                  EXHIBIT 10.13A

      WHEREAS, Landlord and Tenant entered into that certain Lease Agreement
dated as of December 20, 2001, as amended by that certain First Amendment to
Lease dated as of December 20, 2001, as amended by that certain Tri-Party

at 1200 Corporate Drive, Hoover, Alabama 35242; and

      WHEREAS, Landlord and Tenant wish to amend the Lease pursuant to the terms
and conditions hereinafter set forth in this Sixth Amendment.

      NOW, THEREFORE, in consideration of the foregoing and the mutual promises
and covenants contained herein and in the Lease, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged,
Landlord and Tenant hereby agree as follows:

1. As of the date hereof, the Original Premises consist of 10,763 rentable
square feet, consisting of the following:

     *     1,154 rentable square feet of storage space designated as Suite G-42
           (the "G-42 Space");

     *     1,290 rentable square feet of storage space designated as Suite G-45
           (the "G-45 Space");

     *     4,277 rentable square feet of office space designated as Suite 200
           (the "Suite 200 Space"); and

     *     4,042 rentable square feet of office space designated as Suite 400
           (the "Suite 400 Space").

      As of the date hereof, Tenant subleases from Data Center that certain
11,539 rentable square feet of space (the "Data Center Space") as more
particularly described on Exhibit A attached hereto and made a part hereof. The
G-42 Space, the G-45 Space and the G-49 Space (as hereinafter defined) are
sometimes referred to collectively herein as the "Storage Space"; the Suite 200
Space, the Suite 400 Space, the Data Center Space, the Suite 210 Space (as
hereinafter defined) and the Suite 250 Space (as hereinafter defined) are
sometimes referred to herein as the "Office Space"; the Storage Space and the
Office Space are collectively referred to herein as the "Premises" and, from and
after September 1, 2004, are deemed to be the "Premises" demised pursuant to the
Lease, as amended hereby.

2. The expiration date of the Data Lease (as defined in the Tri-Party Agreement)
has been accelerated by Landlord and Data to August 31, 2004, whereupon Tenant's
sublease of the Data Center Space shall automatically terminate. Effective as of
September 1, 2004, Landlord shall lease to Tenant, and Tenant shall lease from
Landlord, the Data Center Space on the terms and conditions of the Lease (other
than the construction, work letter and improvement allowance provisions
thereof), as modified by this Sixth Amendment. From and after September 1, 2004,
the Data Center Space shall be deemed to be a part of Suite 400.

3. Effective on September 1, 2004, Landlord shall lease to Tenant, and Tenant
shall lease from Landlord, that certain 1,649 rentable square feet designated as
Suite 210 as more particularly described on

<PAGE>

Exhibit B-l attached hereto and made a part hereof (the "Suite 210 Space") and

(the "Suite 250 Space"). Further, effective on September 1, 2004, Landlord shall
lease to Tenant, and Tenant shall lease from Landlord, that certain 886 rentable
square feet of space designated as Suite G-49 as more particularly described on
Exhibit B-3 attached hereto and made a part hereof (the "G-49 Space").

4.From and after September 1, 2004, following the addition of the Data Center
Space, the Suite 210 Space, the Suite 250 Space and the G-49 Space, the total
space leased from Landlord to Tenant, and by Tenant from Landlord, pursuant to
the Lease, as amended hereby, equals 31,887 rentable square feet.

5.The Term currently expires on December 31, 2004, subject to the provisions of
Section 2 of the Second Amendment to Lease with respect to the G-45 Space. The
Term is hereby extended, with respect to the entire Premises (i.e., the Office
Space and the Storage Space) through a new Expiration Date of March 31, 2010
(the period commencing September 1, 2004 and expiring March 31, 2010 is herein
referred to as the "Extended Term"). Effective as of the date hereof, the
provisions of Section 2 of the Second Amendment to Lease are deemed to be null
and void and of no further force and effect.

6.All obligations for Base Rent, Operating Expenses, Additional Rent and all
other charges applicable to the Original Premises during the Term shall be
applicable to the entire Premises during the Extended Term, calculated at the
same rates, timing and rates of escalations, except that the Base Year Amount

Expenses for calendar year 2005 and except that Base Rent for the entire

      Base Rent for the entire Premises shall be abated for the period September
1, 2004 through March 31, 2005. With respect to each other full or partial month
during the Extended Term, Tenant shall make Base Rent payments as otherwise
provided in the Lease, as amended hereby. Notwithstanding such abatement of Base
Rent (a) all other sums due under the Lease, as amended hereby, including
Additional Rent and Operating Expenses, shall be payable as provided in the
Lease, as amended hereby, during all full or partial months of the Extended
Term, and (b) any increases in Base Rent set forth in the Lease, as amended
hereby, shall occur on the dates scheduled therefor. The abatement of Base Rent
provided for in this provision is conditioned upon Tenant's full and timely
performance of all of its obligations under the Lease, as amended hereby. If at
any time during the current Term or the Extended Term an event of default by
Tenant occurs and continues beyond the expiration of any applicable notice and
cure periods, then the abatement of Base Rent

                                       -2-
<PAGE>

provided for in this paragraph shall immediately become of no further force and
effect and thereafter, Tenant shall make Base Rent payments for all full or
partial months (or partial months) remaining in the current Term and the
Extended Term without regard to this paragraph.

      Tenant's Share shall be adjusted to 24.88% (calculated as 31,887/128,142)
to reflect the entire Premises during the Extended Term

7. Tenant acknowledges that Landlord has fully performed all tenant improvements
to be performed prior to the date hereof and fully funded all tenant improvement
allowances to be funded prior to the date hereof. Except as set forth on Exhibit
C attached hereto and by this reference made a part hereof, the entire Premises
is delivered to Tenant by Landlord "AS IS, WHERE IS AND WITH ALL FAULTS", and
Landlord is not obligated to perform any tenant improvements therein or to
provide any tenant improvement allowances with respect thereto.

8. The provisions of Section 16 of the Lease (signage) and Section 34 of the
Lease (parking) shall be applicable to the entire Premises as of September 1,
2004, permitting Building standard suite entry signage and Building standard
directory entries to be installed as part of the Work at Tenant's request,
subject to Landlord's prior approval, with the cost thereof paid out of the
Allowance (as hereinafter defined) and establishing the parking ratio available
for use under the terms of the Lease, as amended hereby, to 3.5 spaces per 1,000
square feet in the entire Premises.

9. As of September 1, 2004, Tenant will lease directly from Landlord the "Data
Space" and the "Emageon Space" as each is defined in the Tri-Party Agreement.
Accordingly, from and after September 1, 2004, the Tri-Party Agreement shall be
deemed to be of no further force and effect.

10. The provisions of Section 4(b) of the Fifth Amendment regarding the
"Adjacent Space" are deemed to be of no further force and effect. From and after
the date hereof, Tenant shall have no further rights in the Adjacent Space.

11. Right of Refusal.

      (a)During the Extended Term (excluding any holdover period), so long as
the Lease, as amended, is in full force and effect and no default has occurred
beyond the expiration of any applicable notice and cure periods and no facts or
circumstances then exist which, with the giving of notice or the passage of
time, or both, would constitute a default either at the time of the Offer (as
defined below) or as of the effective date of the proposed expansion of the
Premises to include the Refusal Space as set forth herein, Landlord hereby
grants to Tenant a one-time right of refusal (the "Right of Refusal") to expand
the Premises to include that certain space comprising approximately 6,287
rentable square feet as more particularly described on Exhibit D attached hereto
and by this reference made a part hereof (the "Refusal Space") subject to the
terms and conditions set forth herein and subject and subordinate to prior
rights of other tenants.

      (b) After Landlord has received a "bona-fide" offer to lease Refusal Space
from a third party prospective tenant (as determined by Landlord) and which
Landlord is willing to accept in its sole discretion (the "Third Party Offer"),
Landlord shall not lease the Refusal Space without first offering (the "Offer")
Tenant the right to lease such Refusal Space as set forth herein.
Notwithstanding the foregoing, if the Third Party Offer includes space in excess
of the Refusal Space, such space may be included by Landlord in the Offer and if
so, Tenant must exercise its right hereunder, if at all, as to all (and not any
lesser portion) of the space contained in the Offer. Notwithstanding the
foregoing, if the Third Party Offer is for space less than the entire Refusal
Space, the Refusal Space shall be deemed to be such lesser space and if so,
Tenant must exercise the right hereunder, if at all, as to such lesser portion.

      (c) The Offer shall contain (i) all terms and conditions of the Third
Party Offer; (ii) the date on which Landlord expects the Refusal Space to become
available; and (iii) the increase in Tenant's operating expense percentage. Upon
receipt of the Offer, Tenant shall have the right, for a period of seven (7)
calendar days after receipt of the Offer, to exercise the Right of Refusal by
giving Landlord written notice

                                       -3-
<PAGE>

that Tenant desires to lease the Refusal Space (but not any lesser portion) upon
the same terms and conditions contained in this Lease as amended hereby and as
modified by the terms of Offer; provided, however, that any construction
provisions, improvement allowances, rent abatements or other concessions
applicable to the Premises shall not be applicable to the Refusal Space unless
expressly included in the Offer. Time is of the essence with respect to the
foregoing. Unless otherwise stated in the Offer, the term of the Lease with
respect to the Refusal Space shall be coterminous with the then current demised
term of the Lease and shall be leased to Tenant in its "as is" condition.

      (d) If, within such seven (7) calendar day period, Tenant exercises the
Right of Refusal, then Landlord and Tenant shall amend the Lease to include the
Refusal Space subject to the same terms and conditions as the Lease, as amended
hereby and as modified by the terms and conditions of the Offer; provided,
however, that any construction provisions, improvement allowances, rent
abatements or other concessions applicable to the Premises shall not be
applicable to the Refusal Space unless expressly included in the Offer. If the
Lease is guaranteed now or at any time in the future, Tenant simultaneously
shall deliver to Landlord an original, signed reaffirmation of each Guarantor's
guaranty, in form and substance acceptable to Landlord.

      (e) If, within such seven (7) calendar day period, Tenant declines or
fails to exercise the Right of Refusal, Landlord shall then have the right to
lease the Refusal Space in portions or in its entirety to any third party or
parties without regard to the restrictions in this Right of Refusal and on
whatever terms and conditions Landlord may decide in its sole discretion. If
Tenant so declines or so fails to exercise, this Right of Refusal shall
terminate, this Special Stipulation shall be of no further force and effect, and
Tenant shall have no further Right of Refusal on the Refusal Space.

      (f) This Right of Refusal is personal to EMAGEON UV, INC., a Delaware
corporation f/k/a Emageon, Inc., may not be exercised by any party other than
EMAGEON UV, INC., a Delaware corporation f/k/a Emageon, Inc. and shall become
null and void upon the occurrence of an assignment of the Lease or a sublet of
all or a part of the Premises.

12. Not Used.

13. Option to Renew.

      (a) During the Extended Term (excluding any holdover period), so long as,
both as of the exercise date and as of the first day of the Renewal Term (as
hereinafter defined) the Lease, as amended, is in full force and effect and no
default has occurred and continued beyond the expiration of any applicable
notice and cure period and no facts or circumstances then exist which, with the
giving of notice or the passage of time, or both, would constitute a default,
Landlord hereby grants to Tenant one (1) option to further extend the Extended
Term with respect to all but not any lesser portion of the Premises for a period
of five (5) years beginning immediately upon the expiration of the Extended Term
("Renewal Term"), such option to be exercised by Tenant giving written notice of
its exercise to Landlord in the manner provided in the Lease at least two
hundred seventy (270) days prior, but not more than three hundred sixty (360)
days prior, to the expiration of the Extended Term. Time is of the essence with
respect to the foregoing.

      (b) Base Rent for the Renewal Term shall be the prevailing market rate
(the "Prevailing Market Rate") calculated on a per square foot basis for
comparable renewal leases during the Renewal Term covering the Building and
buildings comparable to the Building (as adjusted for any variances between such
buildings and the Building and as adjusted for other relevant factors,
including, but not limited to, size of space, location of space within the
building, signage rights, age, location and quality of building, length of term,
credit standing of tenant, tenant improvement contributions, leasing commissions
and rent concessions) located in the same market area as the Building
(hereinafter referred to as the "Market Area") to which the Base Year Amount
shall be added.

      Landlord shall, within twenty (20) days after the receipt of Tenant's
notice of exercise, notify Tenant in writing of Landlord's reasonable
determination of the Prevailing Market Rate for the Premises for

                                       -4-

<PAGE>

the Renewal Term. Thereafter, Tenant shall have ten (10) days from its receipt
of Landlord's notice to notify Landlord in writing that Tenant does not agree
with Landlord's determination of the Prevailing Market Rate. If Tenant fails to
object as aforesaid, Landlord's determination shall be deemed to be the
Prevailing Market Rate for the Renewal Term. Upon receipt of Tenant's objection,
Landlord and Tenant shall meet for a period of ten (10) additional days (the
"Negotiation Period") to negotiate the Prevailing Market Rate, with each acting
in good faith. If such negotiations are successful, the rate so negotiated by
the parties will be deemed to be the Prevailing Market Rate for the Renewal
Term. If such negotiations are not successful, the Prevailing Market Rate will
be determined in accordance with the following arbitration procedure:

      Within five (5) days after the expiration of the Negotiation Period,
Tenant shall notify Landlord of Tenant's selection of a real estate broker who
shall act on Tenant's behalf in determining the Prevailing Market Rate. After
Tenant delivers its notice to Landlord as set forth above, Landlord shall notify
Tenant of Landlord's selection of a real estate broker who shall act on Landlord
behalf in determining the Prevailing Market Rate. Within twenty (20) days after
the selection of Tenant's and Landlord's broker, the two (2) brokers shall
render a joint written determination of the Prevailing Market Rate, which joint
determination shall be final, conclusive and binding for the Renewal Term. If
the two (2) brokers are unable to agree upon a joint written determination
within said twenty (20) day period, the two brokers shall select a third broker
within such twenty (20) day period and shall each submit a determination of the
Prevailing Market Rate to such third broker. In the event the two brokers cannot
agree on a third, Landlord or Tenant may request that the local chapter of the
Board of Realtors appoint a party to act as the third broker. Within ten (10)
days after the appointment of the third broker, the third broker shall render a
written determination of the Prevailing Market Rate, which must be either the
Landlord's broker's determination as submitted or the Tenant's broker's
determination as submitted, but no other amount and no compromise between the
two, with the third broker's determination being final, conclusive and binding
on both parties. All brokers selected or appointed in accordance with this
subparagraph shall have at least ten (10) years prior experience in the
commercial office leasing market of the Market Area. If either Landlord or
Tenant fails or refuses to select a broker, the other broker shall alone
determine the Prevailing Market Rate. Landlord and Tenant agree that they shall
be bound by the determination of Prevailing Market Rate pursuant to this
paragraph. Landlord shall bear the fee and expenses of its broker; Tenant shall
bear the fee and expenses of its broker; and Landlord and Tenant shall share
equally the fee and expenses of the third broker, if any.

      (c) Except for the Base Rent, which shall be determined as set forth in
subparagraph B above, leasing of the Premises by Tenant for the Renewal Term
shall be subject to all of the same terms and conditions set forth in the Lease,
as amended; provided, however, that any construction provisions, improvement
allowances, rent abatements or other concessions applicable to the Premises
during the Extended Term shall not be applicable during the Renewal Term (unless
otherwise mutually acceptable to both Landlord and Tenant in the sole discretion
of each at the time Tenant exercises its option to extend). Landlord and Tenant
shall enter into an amendment to the Lease to evidence Tenant's exercise of this
extension option. If the Lease is guaranteed now or at any time in the future,
Tenant simultaneously shall deliver to Landlord an original, signed
reaffirmation of each guarantor's guaranty, in form and substance acceptable to
Landlord.

14. Section 25 of the Lease is hereby modified to provide that Tenant shall
reimburse Landlord for its legal and administrative costs in reviewing any such
proposed assignment or sublease. Section 32 of the Lease is hereby modified to
provide that any estoppel certificate shall include the items listed in such
Section 32 and such other statements as Landlord shall reasonably request.

15. Tenant warrants and represents to Landlord that except for Daniel Realty
Services, L.L.C. and Hazelrig Realty Company, no broker, finder, real estate
agent or other person is entitled to a commission, fee or other compensation in
connection with or as a result of the Lease or the transactions contemplated
hereby or hereunder. The commission of the broker(s) identified above shall be
paid by Landlord pursuant to a separate agreement. Tenant hereby indemnifies and
holds harmless Landlord from any and all claims, losses, costs and damages
(including reasonable attorneys' fees) arising in connection with any claims
against Landlord for broker commissions, fees, or other compensation; the
foregoing indemnity shall not

                                       -5-
<PAGE>

include the fees of the broker(s) identified above if Landlord is responsible
for the commission of such broker(s) as described above.

16. Landlord and Tenant affirm and covenant that each has the authority to enter
into this Sixth Amendment, to abide by the terms hereof, and that the
signatories hereto are authorized representatives of their respective entities
empowered by their respective entities to execute this Sixth Amendment. Upon
Landlord's request, Tenant shall provide evidence of the foregoing to Landlord.

17. To the extent the provisions of this Sixth Amendment are inconsistent with
the Lease, the terms of this Sixth Amendment shall control. Except as expressly
amended or modified herein, all other terms, covenants and conditions of the
Lease shall remain in full force and effect and this Sixth Amendment shall be
binding upon the parties hereto and their respective successors and assigns.
This Sixth Amendment shall be governed by the laws of the State in which the
Building is located. Any terms used in this Sixth Amendment as defined terms,
but which are not defined herein, shall have the meanings attributed to those
terms in the Lease. The submission of this Sixth Amendment to Tenant for
examination or consideration does not constitute an offer to amend the Lease,
and this Sixth Amendment shall become effective only upon the execution and
delivery thereof by both Landlord and Tenant. The Lease, as amended hereby,
contains the entire agreement between the parties with respect to the space
demised by the Lease, as amended, and no representations, inducements, promises,
agreements, oral or otherwise, between the parties not embodied in the Lease, as
amended hereby, shall be of any force and effect. Time is of the essence as to
all of the obligations of Tenant under the Lease and this Sixth Amendment. This
Sixth Amendment has been negotiated "at arm's length" by Landlord and Tenant,
each having the opportunity to be represented by legal counsel. Therefore, this
Sixth Amendment shall not be more strictly construed against either party by
reason of the fact that one party may have drafted this Sixth Amendment. This
Sixth Amendment may be executed by the parties signing different counterparts of
this Sixth Amendment, which counterparts together shall constitute the agreement
of the parties.

                                   EXHIBIT C

                                  WORK LETTER

This WORK LETTER ("Work Letter") is attached to and made part of that certain
Sixth Amendment (to which this Exhibit C is attached). The terms, definitions
and other provisions of the Lease, as amended hereby, are hereby incorporated
into this Work Letter by reference.

In consideration of the execution of the Sixth Amendment and the mutual
covenants and conditions hereinafter contained, Landlord and Tenant agree as
follows:

1. The Work (as hereinafter defined) shall be constructed by Landlord utilizing
"Building Standard" improvements in accordance with the provisions hereof, and
Landlord shall provide to Tenant the allowance set forth below:

      (a) Landlord will provide Tenant a planning allowance (the "Planning
      Allowance") of up to $8,490.00 to be applied to the cost of the Plans (as
      hereinafter defined) for the Suite 210 Space, the Suite 250 Space and the
      G-49 Space. Prior to funding of the Allowance by Landlord hereunder,
      Tenant shall fund or cause to be funded ("Tenant's Planning Contribution")
      the amount by which the cost of the Plans exceeds the Planning Allowance.
      Tenant's Planning Contribution shall be paid prior to the commencement of
      construction of the Work or promptly upon demand therefor by Landlord, if
      such excess (or the exact amount thereof) is not known or anticipated as
      of the commencement of the construction of the Work. So long as the Lease,
      as amended, is in full force and effect and Tenant is not in default
      hereunder (a "Failed Condition"), utilizing the Planning Allowance and
      Tenant's Planning Contribution, if any, Landlord will pay the Architect
      according to the contract with the Architect. In the event of a Failed
      Condition, all costs associated with the Plans shall be payable by Tenant
      upon demand therefor, together with all applicable late charges and
      interest applicable to the nonpayment of Rent hereunder.

      (b) On the terms and conditions set forth in Section 9 below, Landlord
      will provide Tenant an allowance (the "Allowance") of up to $255,285.00 to
      be applied to the costs of the Work. Any portion of the Allowance not
      exhausted by the cost of the Work up to $5.00 per rentable square foot in
      the Premises shall be available to Tenant for reimbursement of actual,
      third-party, documented moving expenses within the Premises,
      telecommunication and computer cabling installation expenses within the
      Premises and/or the cost to purchase furniture, fixtures or equipment
      installed in the Premises as necessary to ready the Premises for Tenant's
      continued occupancy thereof or expansion therein, as applicable, so long
      as Tenant has otherwise complied with the provisions of this Work Letter,
      this Sixth Amendment and the Lease. Tenant shall be eligible for such
      reimbursement upon its presentation to Landlord, on or before the
      expiration of the ninety (90) days following completion of the Work, of
      paid invoices, receipts or other reasonable evidence supporting actual,
      third party expenses incurred by Tenant eligible for this reimbursement
      and any lien waivers or other customary documentation requested by
      Landlord. Time is of the essence with respect to the foregoing. To the
      extent the Allowance is not fully exhausted by the foregoing, Landlord
      shall not be required to fund such excess, with Tenant hereby agreeing to
      release any and all rights thereto. Any costs and expenses for the Work in
      excess of the Allowance shall be paid solely by Tenant.

The term "Building Standard" or "Building standard" as used in this Sixth
Amendment shall mean the standards, materials and specifications set forth by
Landlord for construction of occupied tenant spaces within the Building,
including but not limited to such items as partition standards and details,
doors and door hardware, ceiling grid and tile, HVAC equipment and materials,
light fixtures, carpet and flooring, sprinkler heads, sill finishes and signage.
The Work shall at all time remain the property of the Landlord, subject to
Landlord's rights as set forth in Section 12 and Section 37 of the Lease.

2. With Tenant's cooperation and in accordance with the floor plans attached
hereto , Landlord shall cause Ray Harsh Architects (the "Architect") to prepare,
or cause to be prepared, working drawings for the

                                     - 12 -

<PAGE>

construction of the Building standard items and improvements (together with the
floor plan and all modifications thereof, such drawings are referred to as the
"Plans"). The Plans be subject to compliance with all governmental laws,
regulations and requirements and shall be subject to Landlord's and Tenant's
approval (which approval by each party shall not be unreasonably withheld,
except with respect to items which impact Building systems or structure or which
are visible from the Building's exterior or common areas, in which event
Landlord's prior approval may be withheld in Landlord's sole discretion).
Tenant's failure to approve or disapprove (with specificity) the Plans (or any
modifications thereto) within five (5) days of submission shall be deemed an
approval. In the event Landlord or Tenant disapproves the Plans, Landlord and
Tenant shall meet to promptly resolve any disputes in good faith. The cost of
the Plans shall not be deemed to be a cost of the Work; instead, the Planning
Allowance shall be applied to the cost of the Plans and any amount in excess of
the Planning Allowance shall be paid by Tenant.

3. Utilizing Adams Gilmore & Lynch (the "Designated Contractor"), Landlord shall
diligently prosecute the tenant improvements described in the final, approved
Plans (the "Work") to completion, subject to compliance with all governmental
laws, regulations and requirements. Landlord shall not be obligated to complete
the Work by any particular date, and Landlord and Tenant shall jointly determine
the construction schedule for the Work. In the event completion of the Work (or
any portion thereof) continues beyond September 1, 2004, Landlord and the
Designated Contractor shall be allowed to enter upon the Premises at any
reasonable times thereafter as necessary to complete such Work (or portion
thereof), and such entry shall not constitute an actual or constructive eviction
of Tenant, in whole or in part, nor shall it entitle Tenant to any abatement or
diminution of rentals or relieve Tenant from any obligation under the Lease, as
amended hereby.

4. Subject to the provisions of Section 10 below, in the event Tenant, utilizing
its own limited service contractors and vendors, will undertake certain limited
portions of the improvements to the Premises, such as relocation or installation
of cabling, systems, furniture and related items, Tenant shall use licensed
contractors, approved by Landlord, such approval not to be unreasonably
withheld. Tenant shall advise its contractors and vendors that no interest of
the Landlord in the Premises, the Building or the Project shall be subject to
liens to secure payment of any amount due such contractors or vendors. Tenant
shall also be responsible to ensure that such limited service contractors and
vendors do not impede the Designated Contractor in performance of the Work.
Landlord shall not be liable in any way for any injury, loss, damage or delay
which may be caused by or arise from Tenant or such limited service contractors
or vendors. Such limited service contractors and vendors shall be obligated to
observe Landlord's construction rules and regulations for the Building, as such
may be adopted and amended from time to time. Tenant's limited service
contractors and vendors shall be responsible for the removal of trash and debris
resulting from the performance of their work, and such trash and debris removal
shall be undertaken at such time and in such manner as designated by Landlord.

5. Landlord or its agent may attend any and all design and preconstruction
meetings with Tenant and the Architect or their representatives as Landlord
shall deem necessary to inform the various parties of the minimum requirements
for design and construction, to assure compliance with the terms of this Work
Letter, to coordinate construction of the Premises or for any other reason
deemed necessary by Landlord.

6. Any approval by Landlord of, or consent by Landlord to, any plans,
specifications or other items to be submitted to and/or reviewed by Landlord
pursuant to this Sixth Amendment shall be deemed to be strictly limited to an
acknowledgment of approval or consent by Landlord thereto, and such approval or
consent shall not constitute the assumption by Landlord of any responsibility
for the accuracy, sufficiency or feasibility of any plans, specifications or
other such items and shall not imply any acknowledgment, representation or
warranty by Landlord that the design is safe, feasible, structurally sound or
will comply with any legal or governmental requirements, with Tenant being
responsible for all of the same. Subject to the provisions of Section 12 and 37
of the Lease, the Work shall at all time remain the property of the Landlord and
shall not be subject to levy, sale or other encumbrance or transfer by Tenant.

7. If Tenant desires any changes in the Work after having approved the initial
Plans, Tenant shall be required to sign such change orders as requested by
Landlord or the Designated Contractor prior to the commencement of Work
incorporating the relevant change order, and may, upon request of Landlord, be

                                      -13-
<PAGE>

required to deliver to Landlord evidence of financing or financial capability of
Tenant sufficient to cover the excess cost, if any, resulting from such change
order. Any such changes shall be subject to Landlord's approval in accordance
with the standards set forth in Section 2 above. The additional cost of any such
change orders shall be considered a cost of the Work.

8. Notwithstanding anything provided in the Lease or herein to the contrary, in
the event Tenant elects (with Landlord's approval) to use materials other than
Building Standard, Landlord shall have no obligation to provide services which
are materially different from those provided for Building Standard improvements
(including, without limitation, janitorial and cleaning services) for any
non-Building standard improvements installed, constructed or used in the
Premises.

9. Prior to funding of the Allowance by Landlord hereunder, Tenant shall fund or
cause to be funded (as "Tenant's Contribution") the amount by which the cost of
the Work and all other costs arising pursuant to this Work Letter, exceeds the
Allowance. Tenant's Contribution shall be paid prior to the commencement of
construction of the Work or promptly upon demand therefor by Landlord, if such
excess (or the exact amount thereof) is not known or anticipated as of the
commencement of the construction of the Work. So a Failed Condition has not
occurred, utilizing the Allowance and Tenant's Contribution, if any, Landlord
will pay the Designated Contractor in periodic payments as construction
progresses according to the contract with the Designated Contractor. In the
event of a Failed Condition, all costs associated with the Work, the Plans and
this Work Letter shall be payable by Tenant upon demand therefor, together with
all applicable late charges and interest applicable to the nonpayment of Rent
hereunder.

10. Landlord, at Landlord's discretion (not to be unreasonably withheld), may
permit Tenant and Tenant's agents to enter the Suite 210 Space, the Suite 250
Space and/or the G-49 Space prior to September 1, 2004 in order that Tenant may
do such other work as may be required by Tenant to make the Suite 210 Space, the
Suite 250 Space and/or the G-49 Space ready for Tenant's use and occupancy. If
Landlord permits such early entry, such permission is conditioned upon Tenant
and its agents, contractors, employees and invitees working in harmony and not
interfering with Landlord and its agents, contractors and employees in doing the
Work or for other tenants and occupants of the Building. If at any time such
entry shall cause or threaten to cause disharmony or interference, Landlord
shall have the right to withdraw such permission upon 24 hours notice to Tenant.
Tenant agrees that any such entry into and occupation of the Suite 210 Space,
the Suite 250 Space and/or the G-49 Space shall be deemed to be under all of the
terms, covenants, conditions and provisions of the Lease, as amended hereby,
except as to the covenant to pay Base Rent and Operating Expenses, and further
agrees Landlord shall not be liable in any way for any injury, loss or damage
which may occur to any of Tenant's work and installations made in the Premises
or to property placed therein prior to September 1, 2004, the same being at
Tenant's sole risk.
