                                 LEASE AGREEMENT

         THIS LEASE AGREEMENT (this "Lease") is made and entered into between
SPALDING TRIANGLE, L.L.C., a Georgia limited liability company (hereinafter
referred to as "Landlord") and SEROLOGICALS CORPORATION, a Delaware corporation
(hereinafter referred to as "Tenant"):

WITNESSETH:

         1.       LEASED PREMISES.

         In consideration of the rents, terms, provisions and covenants of this
Lease, Landlord hereby leases lets and demises to Tenant and Tenant hereby
leases and takes, the following described premises (herein referred to as the "
Premises"): that certain office building, excluding the roof thereof, located at
5655 Spalding Drive, Norcross, Georgia (herein sometimes referred to as the
"Building"), containing approximately 49,720 square feet of rentable area. The
Building is a part of the three-building project commonly known as Spalding
Triangle Phase I (the land and the improvements of said three-building project
which are generally located at 3770 Data Drive, 3790 Data Drive, and 5655
Spalding Drive, are herein sometimes collectively referred to as the "Project").
A floor plan of the interior of the Premises is attached hereto as Exhibit "A".
Tenant shall have no right of access to, and no right to utilize or install any
machinery, signs or equipment upon, the roof of the Building for any purpose
without the prior written consent of Landlord in Landlord's sole discretion.
Upon and subject to the provisions of Section 9 below and Section 10 of Exhibit
"C" attached hereto, Tenant is granted access to the roof of the Building for
purposes of maintaining, repairing and replacing the air conditioning units
servicing the Premises and for installing and using a satellite dish. Landlord
and Tenant agree that the Premises consist of 49,720 square feet of rentable
area regardless of the actual number of square feet of rentable area, and
neither Landlord nor Tenant shall have the right to demand a change in the rent
or terms of this Lease based on any remeasurement of the Premises, change in
commonly-used measurement standards, or otherwise. In addition to the interest
in the Premises demised to Tenant under this Lease, Landlord hereby grants
Tenant a nonexclusive license for so long as this Lease is in full force and
effect to use the "Common Areas", hereinafter defined, of the Project in common
with others entitled to use the Common Areas, including Landlord and other
tenants of the Project and their respective employees and invitees and other
persons authorized by Landlord, subject to the terms and conditions of this
Lease (including, without limitation, subject to the provisions of Section 6 of
Exhibit "C" attached hereto), including any and all rules and regulations
promulgated by Landlord in accordance with the terms of this Lease. As used
herein, the term "Common Areas" means all areas and facilities in the Project
that are provided and designated from time to time by Landlord for the general
nonexclusive use and convenience of Landlord, Tenant, and all other tenants of
the Project and their respective employees, invitees, licensees, or other
visitors, and may include, without limitation, the driveways and loading areas
of the Building, and the walkways, parking and landscaped areas of the Project.
Landlord may from time to time change the size, use, shape, configuration or
nature of any portion of the Common Areas, so long as such change does not
materially deprive Tenant of the benefit and enjoyment of the Premises. Neither
Landlord nor Landlord's agents have made any representations, warranties or
promises with respect to the Project, the physical condition of the Building,
the land upon which it is erected, or the Premises, or any matter or thing
affecting or related to the Premises except as expressly and specifically set
forth in this Lease. Subject to the other terms and conditions of this Lease,
Landlord grants Tenant access to the Premises twenty-four (24) hours per day
commencing on the Commencement Date.

         2.       TERM.

         Subject to and upon the conditions set forth below, the term of this
Lease shall be for one hundred twenty-two (122) months, and shall commence at
12:01 A.M. on January 1, 2001 (the "Commencement Date"); provided, however, if
Landlord is unable to deliver the Premises to Tenant with the Initial
Improvements (as defined in Exhibit B) substantially completed on or before
January 1, 2001 for any reason other than Tenant Delay (as defined herein), then
the Commencement Date shall be delayed until the date on which the Initial
Improvements are substantially complete, and the term of this Lease shall end at
midnight on the last day of the 122nd full calendar month following the
Commencement Date, unless sooner terminated as hereinafter provided (herein
called the "Lease Term" or the "Term"). If the Commencement Date does not occur
on or before March 1, 2001, for any reason other than Tenant Delay or Force
Majeure Delay (as defined herein), Landlord shall grant to Tenant as a credit
against Base Rent, as liquidated damages, the amount of $1,000.00 for each day
between March 1, 2001 and the date the Premises are delivered to Tenant by
Landlord with the Initial Improvements therein substantially completed. The
total amount of such liquidated damages shall be applied against the Base Rent
first accruing under this Lease. Any such liquidated damages shall be in
addition to the delay in the Commencement Date. Landlord's grant of such
liquidated damages to Tenant pursuant to this paragraph shall be Tenant's sole
remedy against Landlord as a result of such delay in the Commencement Date and
Tenant shall have no right to terminate this Lease as a result of such delay
except as otherwise expressly and specifically provided in the immediately
following sentence. If the Commencement Date does not occur on or before June 1,
2001, for any reason other than Tenant Delay or Force Majeure Delay, Tenant
shall have the right to terminate this Lease by giving Landlord written notice
of termination on or before the date on which the Initial Improvements are
substantially complete, and Landlord and Tenant shall thereupon be released from
all obligations under this Lease; provided, however, if the Initial Improvements
shall have been substantially completed on or before the date which is ten (10)
days after Landlord's receipt of such notice, then such termination notice shall
be deemed null and void and this Lease shall remain in full force and effect.

         3.       BASE RENT

         (a)      Throughout the full Term of this Lease, Tenant hereby agrees
to pay to Landlord a base annual rental (herein referred to as "Base Rent") in

The Base Rent shall be due and payable on the first day of each calendar month
during the initial Lease Term and any extensions or renewals hereof, and Tenant
hereby agrees to so pay such rent and all other rental hereunder to Landlord at
c/o ELV Associates, Inc., P.O. Box 84-5028, Boston, MA 02284-5028 (or such other
address as may be designated by Landlord from time to time) monthly in advance
without deduction, setoff, or prior demand. A prorated monthly installment,
based on a thirty (30) day month, shall be paid in advance of any fraction of a
month if the Lease Term shall begin on any date except the first day or shall be
terminated on any date except the first day or shall be terminated on any date
except the last day of any month. At all times that Landlord shall direct Tenant
to pay Base Rent or Additional Rent to a "lockbox" or other depository whereby
checks issued in payment of rental are initially cashed or deposited by a person
or entity other than Landlord (albeit on Landlord's authority), then, for any
and all purposes under this Lease, in the event Landlord contends Tenant is in
default under this Lease or Tenant tenders less than the full amount of Base
Rent or Additional Rent due Landlord upon any payment to Landlord, then: (i)
Landlord shall not be deemed to have accepted such payment until ten (10) days
after the date on which Landlord shall have actually received such funds, and
(ii) Landlord shall be deemed to have accepted such payment if (and only if)
within said ten (10) day period, Landlord shall not have refunded (or attempted
to refund) such payment to Tenant. Nothing contained in the immediately
preceding sentence shall be construed to place Tenant in default of Tenant's
obligation to pay rent, or to require Tenant to pay any late charge or default
interest, if and for so long as Tenant shall timely pay the rent required
pursuant to this Lease in the manner designated by Landlord.

         Notwithstanding the foregoing to the contrary, the payment of Base Rent
described in this subsection 3(a) above shall be excused during the first sixty
(60) days of the initial Lease Term (although Base Rent shall continue to accrue
during such period). However, if Tenant defaults under this Lease beyond any
applicable period of notice and cure with respect to any monetary or material
non-monetary obligation of Tenant under this Lease, any remaining excused Base
Rent shall cease from the date of such default. Except for the sixty (60) days
of Base Rent which may be excused pursuant to the provisions of this subsection
3(a), no other Base Rent or Additional Rent payable by Tenant under this Lease
shall be excused or abated, and without limiting the generality of the
foregoing, no Base Rent shall be excused during any Renewal Term.

         (b)      [Intentionally Omitted].

         (c)      Other remedies for nonpayment of rent notwithstanding, if the
monthly Base Rent payment or any other rental due hereunder is not received by
Landlord on or before the tenth day of the month for which rent is due, a
service charge of five percent (5%) per month of all past due amounts owed on
such date shall become due and payable in addition to the regular rent owed
under this Lease and shall be treated as Additional Rent.

         (d)      In the event Tenant owes any sums to Landlord pursuant to the
terms of this Lease, and the same are not timely paid within applicable notice
and cure periods, Tenant agrees that such sums shall accrue interest until paid
at the Prime Rate plus four percent (4%) per annum (herein referred to as the
"Default Rate"). As used herein, the term "Prime Rate" means the prime rate of
interest published in the Money Rates Table in the Wall Street Journal, or if
unavailable in the Wall Street Journal, as published in the Money Rates Table in
the New York Times, or if unavailable in the New York Times, the prime rate of
interest announced publicly from time to time by Citibank, N.A., New York, New
York, or its successor, or should Citibank, N.A., or its successor, abolish or
abandon the practice of publishing its prime rate at any time during the Term,
then Landlord and Tenant shall mutually agree upon a comparable reference rate
which shall be deemed to be the Prime Rate hereunder.

4.       ADDITIONAL RENT OPERATING EXPENSES.

         All sums other than the Base Rent due hereunder shall constitute
"Additional Rent" including without limitation:

         (a)      Taxes.

                  (i) During the Lease Term, Tenant shall pay to Landlord, as
Additional Rent, Tenant's Share (as such term is hereinafter defined) of taxes
and assessments (as hereinafter defined) for the Project (the "Tax Charges").
The term "taxes and assessments" shall include all real estate taxes,
assessments, sewer rents and water charges, governmental levies, municipal
taxes, county taxes or any other governmental charge, general or special,
ordinary or extraordinary, unforseen as well as foreseen, of any kind or nature
whatsoever, which may be assessed, levied or imposed upon all or any part of the
Project and the sidewalks, plazas or streets in front of or adjacent thereto,
and levied against Landlord and/or the Project and/or the real estate upon which
the Project is located, or upon the operation of the Project, or any part
thereof, under the laws of the United States, the State of Georgia, or any
political subdivision thereof, or the County of Gwinnett, or any political
subdivision thereof, and any charge by any business improvement district. Taxes
shall not include any penalties or interest imposed upon Landlord in connection
with the late payment thereof. Currently there are no tax exemptions or
abatements in effect affecting the taxes and assessments. Reasonable fees and
expenses incurred by Landlord in obtaining or attempting to obtain a reduction
of or in the contest of any taxes or assessments shall be added to and included
in the amount of taxes and assessments. The term "taxes and assessments" shall,
notwithstanding anything to the contrary contained herein, exclude any net
income, sales, transfer or "value added" tax, inheritance tax or estate tax
imposed or constituting a lien upon Landlord or all or any part of the Project,
except to the extent that any of the foregoing are hereafter assessed against
owners or lessees of real property in their capacity as such (as opposed to any
such taxes which are of general applicability). The term "taxes and assessments"
shall also exclude any taxes are separately and specifically assessed against
any above building-standard leasehold improvements in another tenant's leased
premises at the Project. Further, notwithstanding anything to the contrary
contained herein, the term "taxes and assessments" shall in no event include
charges for steam, gas, electricity or other utilities.

                  (ii) If at any time during the Term of this Lease, the present
method of taxation shall be changed so that in lieu of the whole or any part of
any taxes, assessments of governmental charges levied, assessed, or imposed on
real estate and the improvements thereon, there shall be levied, assessed or
imposed on Landlord a capital levy or other tax directly on the rents received
therefrom and/or a franchise tax, assessment, levy or charge measured by or
based, in whole or in part, upon such rents for the present or any future
building or buildings on the Premises, then all such taxes, assessments, levies
or charges, or the part thereof so measured or based, shall be deemed to be
included within the term "taxes and assessments" for the purposes hereof.

                  (iii) Tenant shall pay, or cause to be paid, before
delinquency, any and all taxes levied or assessed during the Term of this Lease
upon all improvements installed by Tenant in the Premises (expressly excluding
the Initial Improvements), Tenant's other leasehold improvements, equipment,
furniture, fixtures and any other personal property located on the Premises. In
the event any or all of said improvements, Tenant's other leasehold
improvements, equipment, furniture, fixtures and other personal property shall
be assessed and taxed with the Premises or the Project, Tenant shall pay to
Landlord its share of such taxes within ten (10) calendar days after delivery to
Tenant by Landlord of a statement in writing setting forth the amount of such
taxes attributable to the above property.


                                       4
<PAGE>   5

                  (iv) Landlord shall provide Tenant with a copy of the annual
tax bill(s) for the Project promptly upon Landlord's receipt of the same from
the applicable taxing authority each year during the Term of this Lease. For so
long as Tenant leases all of the rentable square feet in the Building, Tenant
shall have the right, upon written notice to Landlord, to require Landlord to
contest the validity and/or amount of any taxes and assessments, provided that
(x) Tenant agrees (and Tenant hereby so covenants and agrees) to indemnify and
hold Landlord harmless from and against any and all loss, cost and expense
(including reasonable attorneys' fees) incurred by Landlord in connection with
such proceedings, and (y) in the event any such taxes or assessments on all or
any part of the Project are increased as a result of such contest, Tenant shall
pay the entire amount of any such increase in taxes and assessments on the
Project to Landlord within ten (10) days of Tenant's receipt of written demand
therefor. Notwithstanding the foregoing, in the event any other tenant in the
Project has the right to contest taxes and assessments with respect to all or a
portion of the Project and taxes and assessments are increased as a direct
result of such contest maintained by another tenant in the Project, Tenant's
share of taxes and assessments on the Project shall not include any portion of
such increase in taxes and assessments.

         (b)      Insurance. During the Term of this Lease, Tenant shall pay to
Landlord, as Additional Rent, Tenant's Share of insurance (as hereinafter
defined) for the Project (the "Insurance Charges"). The term "insurance" shall
include all fire and extended casualty insurance on the Project and all
liability coverage on the grounds, sidewalks, driveways, parking areas, and any
other exterior or interior areas of the Project, together with such other
insurance protections, including, but not limited to, rents insurance (not
exceeding twelve (12) months), as are from time to time obtained by Landlord.
The term "insurance" shall also include any deductible amount paid by Landlord
in connection with any insured loss.

         (c)      CAM. During the Term of this Lease, Tenant shall pay to
Landlord, as Additional Rent, Tenant's Share of all direct costs of managing,
operating and maintaining the Project, the Common Areas and any appurtenances
thereto (the "CAM Charges"), including, without limitation, all Common Area
electrical, grounds maintenance charges, security services and other common area
charges and expenses for the Project, as provided in subsection (d) below. The
term "grounds maintenance" shall include, without limitation, all landscaping,
planting, lawn and grounds care, all repairs, maintenance, replacements and
improvements to the grounds and other common areas adjacent to the Premises and
to all Common Areas, including without limitation all sidewalks, driveways,
loading areas and parking areas. The term "CAM Charges," as used and defined
under this Lease, shall not, however, include the following items:

                  amortization of capital items permitted pursuant to Section
                  4(d) hereinbelow);

                  the Project, whether at the expense of Landlord or such
                  tenant, to the extent that such work or services are in excess
                  of the work or services which Landlord is required to furnish
                  or is furnishing to Tenant under this Lease;

         (7)      the cost of any repairs made by Landlord to remedy damage to

                  the Project.

         (d)      Capital Expenditures /Mandated Alterations.

                  If, for any reason, including imposition of governmental
requirements, laws or regulations, Landlord shall expend monies directly or
indirectly which are intended to reduce the energy consumption of the Project
and which, by generally accepted accounting principles are treated as capital
expenditures, the annual CAM Charges of the Project shall also include the
amortization of such capital expenditures based upon a useful life acceptable to
the appropriate taxing authority provided Tenant receives the benefit of such
reduced consumption by way of a percentage reduction in Tenant's monthly prorata
share of CAM Charges. In the event that any local, state or federal government
shall, by any legally enforceable legislative, administrative or judicial
action, whether by ordinance, act, statute, order, mandate, rule, regulation or
otherwise, require during the Term of this Lease any alteration of or
improvement to any portion of the Project, excluding the Premises (a "Mandated
Alteration"), which, by generally accepted accounting principles would be
treated as a capital expenditure, then, provided that such Mandated Alteration
is the result of the adoption of a new or changed ordinance, act, statute,
order, mandate, rule or regulation or interpretation thereof not existing on the
Commencement Date of this Lease, the annual CAM Charges shall also include the
annual amortization of such capital expenditure based upon a useful life of not
less than five (5) years; provided however, that in no event shall the annual
Additional Rent assessed to Tenant that is attributable to such Mandated
Alteration exceed twenty cents ($.20) multiplied by the rentable square footage
of the Premises. To avoid any doubt, Landlord will not double charge Tenant for
any cost permitted to be passed through to Tenant under Section 4(c) above and
under this Section 4(d).

         (e)      Estimated Payments.

                  (i) Prior to the Commencement Date and prior to January 1 of
each subsequent calendar year during the Term of this Lease, or as soon
thereafter as possible, Landlord shall deliver to Tenant an estimate of (A) the
Tax Charges for that calendar year (the "Tax Estimate"), (B) the Insurance
Charges for that calendar year (the "Insurance Estimate"), and (C) the total CAM
Charges for that calendar year (the "CAM Estimate") and Tenant's Share thereof.
Landlord shall use commercially reasonable efforts to deliver such estimate to
Tenant by no later than April 1 of each year during the Term. The Tax Estimate,
the Insurance Estimate and the CAM Estimate are sometimes referred to
hereinafter collectively as the "Common Cost Estimates". The initial Common Cost
Estimates for calendar year 2000 is $1.41 per rentable square foot of the
Premises. The Common Cost Estimates for any subsequent calendar year shall not
exceed 103% of the Common Cost Estimates for the immediately


                                       7
<PAGE>   8

preceding calendar year, on an aggregate basis (as opposed to a line-by-line or
component basis), unless there is a reason for a greater percentage increase and
Landlord provides Tenant with information relating thereto. The preceding
sentence is not intended and shall not be construed to limit or cap in any way
the amount of Additional Rent which may become due and payable pursuant to the
provisions of subsection 4(e)(ii) below. Tenant shall thereafter during that
calendar year pay to Landlord one-twelfth (1/12) of the amount of Tenant's Share
of the Common Cost Estimates at the same time its monthly installments of Base
Rent hereunder are due and payable. In the event Landlord shall not have
furnished the Common Cost Estimates to Tenant by January 1 of any calendar year,
then until the first day of the second month next following the month in which
the Common Cost Estimates are furnished to Tenant, Tenant shall pay to Landlord
on the first day of each calendar month an amount equal to the aggregate monthly
installment of Tenant's Share of the Tax Charges, Insurance Charges and CAM
Charges which was payable by Tenant to Landlord with respect to the last month
of the preceding calendar year. In such event, at such time as Landlord
furnishes the Common Cost Estimates to Tenant, Landlord shall give Tenant notice
stating whether the aggregate amount of the installments of Tenant's Share of
the Tax Charges, Insurance Charges and CAM Charges previously paid for such
calendar year is more or less than the aggregate amount of the installments due
for such portion of the calendar year as computed in accordance with the Common
Cost Estimates, and (A) if there shall be a deficiency, then within thirty (30)
days after the Tenant receives the Common Cost Estimates, Tenant shall pay the
amount of such deficiency, (B) if there shall have been an overpayment, Landlord
shall credit Tenant in the amount thereof toward the subsequent installments of
the Tax Charges, Insurance Charges and CAM Charges, and (C) on the first day of
the second month next following the month in which the Common Cost Estimates are
furnished to Tenant, and monthly thereafter for the balance of such calendar
year, Tenant shall pay to Landlord one-twelfth (1/12) of the amount of Tenant's
Share of the Tax Charges, Insurance Charges and CAM Charges as set forth in the
Common Cost Estimates.

                  (ii) At such time as Landlord is able to determine the actual
Tax Charges, Insurance Charges and CAM Charges for each calendar year, Landlord
shall deliver to Tenant a statement thereof (including a break down of the
charges) and, in the event the estimated Tax Charges, Insurance Charges and CAM
Charges differ from the actual Tax Charges, Insurance Charges and CAM Charges,
then (A) if there shall be a deficiency, then within thirty (30) days after
Tenant receives the statement of the actual Tax Charges, Insurance Charges and
CAM Charges, Tenant shall pay the amount of such deficiency, and (B) if there
shall have been an overpayment, Landlord shall credit Tenant in the amount
thereof toward the subsequent installments of the Tax Charges, Insurance Charges
and CAM Charges coming due in the next calendar year. Landlord shall use
commercially reasonable efforts to deliver such statement to Tenant by no later
than April 1 of each year during the Term commencing in calendar year 2002, but
Landlord's failure to deliver any such statement to Tenant by April 1 of any
calendar year shall not affect Tenant's obligation to pay the amount of any such
deficiency. If such statement is not delivered to Tenant by April 1 of any
calendar year and if Tenant shall have made an overpayment requiring a credit as
provided in (B) above, then, in those events, there shall be added to such
credit interest at the Default Rate from April 1 to the date on which such
statement is delivered to Tenant. If such statement with respect to any calendar
year of the Term is not delivered to Tenant on or before the date which is two
(2) years after the end of the Term, then Tenant shall not be responsible for
any deficiency described in (A) above which is applicable to the calendar year
for which Tenant has not received such statement.

         (f)      "Tenant's Share", as used herein, shall mean the number,
stated as a percentage, determined by dividing the rentable square footage of
the Premises as stated in Section 1 by the number rentable square feet in the
improvements in the Project. Landlord represents and warrants that as of the
date of this Lease, the Project contains approximately 91,213 square feet of
rentable area; therefore, the parties


                                       8
<PAGE>   9

thereto stipulate and agree that the initial Tenant's Share shall be 54.51%. In
the event of any change in the area (in rentable square feet) of the Premises or
the Project, Tenant's Share shall be adjusted to reflect such change on a
prorated, daily basis. Without limiting the generality of the foregoing, if the
physical size of the rentable area of the improvements in the Project increases,
then Tenant's Share shall be adjusted to reflect such change in accordance with
the foregoing formula.

         (g)      Any payment to be made pursuant to this Section 4 with respect
to the calendar year in which this Lease commences or terminates shall be
prorated.

         (h)      Subject to the terms and conditions in this paragraph, Tenant
shall have the right to cause an audit of Landlord's books and records for the
purpose of determining the accuracy of the CAM Charges charged to Tenant and
Landlord's compliance with this Lease with respect thereto. In addition, from
time to time upon demand of Tenant, Landlord shall provide Tenant with
reasonably satisfactory backup documentation as to applicable costs and
expenses. Tenant and a commercially recognized certified public accounting firm
shall have the right to inspect and/or audit Landlord's records at Landlord's
office upon at least ten (10) days' prior notice during normal business hours
during the one hundred eighty (180) days following the respective delivery of
Landlord's annual statement of actual CAM Charges for the preceding calendar
year. Tenant agrees that such inspection and/or audit shall be conducted in a
manner designed not to unreasonably interfere with the conduct of Landlord's
business. The inspection and/or audit shall be limited to that portion of
Landlord's books and records pertaining only to the CAM Charges for the
preceding calendar year, unless the inspection and/or audit proves that
Landlord's calculation of CAM Charges was in error, in which case Tenant shall
have the right to inspect and/or audit Landlord's books and records for prior
years pertaining only to such erroneous component of CAM Charges. Tenant and
such certified public accountant must agree, in their contract for such
services, to such confidentiality restrictions and shall specifically agree that
the results shall not be made available to any other tenant of the Project. The
results of any such inspection and/or audit shall be kept confidential by Tenant
and its officers and employees (except for such disclosures required by law or
in connection with any arbitration with Landlord as provided in this paragraph
below). Unless Tenant sends to Landlord any written exception to Landlord's
annual report within said one hundred eighty (180) day period, along with a
written copy of Tenant's audit results, such report shall be deemed final and
accepted by Tenant. Tenant shall pay the amount shown on Landlord's annual
statement of actual CAM Charges in the manner prescribed in this Lease, whether
or not Tenant takes any such written exception, without any prejudice to such
exception. If Tenant makes a timely exception, Landlord may cause its
independent certified public accountant or shall select and cause another firm
with at least five (5) years of experience in auditing the books and records of
commercial office projects to issue a report in response to Tenant's exception.
Any dispute between Landlord and Tenant with respect to CAM Charges arising by
reason of Tenant's audit shall be determined by arbitration by a panel of three
arbitrators in accordance with the then current rules and regulations for
commercial matters of the American Arbitration Association or its successor
(hereinafter referred to as the "AAA"). The determination of the arbitrators
shall be final, binding and conclusive on Landlord and Tenant, and judgment may
be rendered thereon by any court having jurisdiction, upon application of either
Landlord or Tenant. Each party shall have the right to select one of the
arbitrators, and the third arbitrator, who shall be a competent and impartial
person with at least ten (10) years' experience in office management accounting
in the metropolitan Atlanta area, shall be selected by the other two arbitrators
or, failing agreement by them, the AAA. The fees and expenses of the arbitrators
under this subsection shall be borne equally by both parties.

         5.       SIGNS; LIGHTING.

         Tenant shall not, without Landlord's prior written consent:

                  (a)      install, alter or replace any exterior lighting,
decorations, exterior paintings, awnings, canopies or the like, or

                  (b)      erect, install, alter or replace any signs, window or
door lettering, placards, decorations or advertising media of any type which can
be viewed from the exterior of the Premises, except for Tenant's illuminated
logo to be placed in the lobby of the Premises which Landlord hereby approves.
All of the same shall be subject to the sign criteria established by Landlord
for the Project from time to time in the exercise of its sole discretion, and
shall be subject to the prior written approval of Landlord as to construction,
method of attachment, size, shape, height, lighting, color and general
appearance. Tenant shall be solely responsible for all costs associated with the
installation and maintenance of such signs. All signs are subject to applicable
laws and deed restrictions and shall conform to any national, local or municipal
ordinance or regulation. All signs shall be kept in good condition and in proper
operating order at all times. At Landlord's option and request, Tenant shall
remove all signs at the termination of this Lease, and shall repair any damage
and close any holes caused by such removal, with such repairs to be made in a
good workmanlike manner. Tenant shall not erect any signs on the roof or paint
or otherwise deface the exterior walls of the Building.

         6.       USAGE AND INSURANCE.

         The Premises shall be used only for the purpose of general office use
and other customary uses related to the use of the Premises as a first-class
office building, including the operation of a data center, the operation of a
copy center for Tenant's internal use, and the operation of a lunchroom or
cafeteria for use by Tenant's employees and invitees (but not for the sale of
food or other products to the general public). Under no circumstances shall
Tenant be permitted to use, maintain, store or dispose of any blood or plasma
products within the Project or the Premises, whether in connection with Tenant's
business operations or otherwise. Tenant shall comply with all governmental
laws, ordinances and regulations applicable to the use of the Premises, and
shall promptly comply with all governmental orders and directives for the
correction, prevention and abatement of nuisances in, upon, or connected with
the Premises, all at Tenant's sole expense. Without Landlord's prior written
consent, Tenant shall not receive, store or otherwise handle any product,
material or merchandise which is explosive or highly inflammable or any other
hazardous substance, other than customary cleaning products and office supplies
in reasonable quantities, subject always to the provisions of Section 22 below.
Tenant will not permit the Premises to be used for any purpose which would
render the insurance thereon void or the insurance risk more hazardous (unless
Tenant pays the entire amount of any increase in Landlord's Insurance Charges
resulting from such increased risk); nor shall the Premises be used for any
illegal purposes; nor in violation of any regulation of governmental body; nor
in any manner to create any nuisance or trespass. If the insurance premiums on
the building in which premises are located are increased due to Tenant's use of
the Premises, then, Tenant shall pay such increase in premium as Additional
Rent.

         7.       JANITORIAL SERVICE.

         Tenant, at its own cost and expense, shall pay all charges for
janitorial services performed in the Premises during the Term of this Lease.
Tenant shall contract with a the janitorial services company.


                                       10
<PAGE>   11

         8.       SERVICES.

         (a)      Tenant, at its sole cost and expense, shall pay all charges
for gas and electricity used or consumed by Tenant or others from the Premises
or any portion thereof during the Term of this Lease. Such charges shall be paid
by Tenant directly to the applicable utility company. Upon Landlord's request
from time to time no more than twice annually (or at any time in the event
Landlord receives notice from any utility provider that such charges have not
been timely paid by Tenant), Tenant shall provide evidence to Landlord that
Tenant has paid such utility charges in full to the applicable utility company.
In addition, Tenant agrees to reimburse Landlord semi-annually and immediately
upon ten (10) business days' notice, as Additional Rent hereunder, Tenant's
Share of any and all water charges incurred by, at or from the Building. If the
water to the Building is separately metered, then notwithstanding anything
contained to the contrary in this Lease, Tenant's Share of such water charges
shall be 100%.

         (b)      Tenant shall pay all telephone charges for services contracted
for by or on behalf of Tenant or other occupant of the Premises or any portion
thereof.

         (c)      Failure in the provision or furnishment of any of said
services, or any cessation thereof, resulting from any cause whatsoever shall
neither render Landlord liable in any respect for damages to either person or
property, be construed as an eviction of Tenant, work an abatement of rent nor
relieve Tenant from fulfillment of any covenant of this Lease. Landlord agrees
that Landlord shall not divert or otherwise reduce the present electrical
capacity of the Building during the Term of this Lease for use by any other
portion of the Project or other tenant therein. Should any of the equipment or
machinery break down, or for any cause cease to function properly, Tenant shall
repair the same properly, and Tenant shall have no claim for rebate of rent or
damages on account of any interruptions in service occasioned from the repairs.

         9.       REPAIRS AND MAINTENANCE.

         (a)      Landlord agrees that it shall at all times, at its sole cost
and expense, keep the roof of the Building and the structural walls (excluding
windows, window glass, plate glass and all doors), the structural floors, the
structural beams/columns of the Building, and the foundation of the Building in
good repair and condition, reasonable wear and tear and any damage caused by
Tenant or Tenant's employees, officers, servants, agents, contractors,
subcontractors, assignees, sublessees, licensees or invitees or persons employed
by any of them excepted. If any exterior glass is destroyed or displaced as a
result of a defect in the structure of the Building or as a result of needed
maintenance or repairs to the structure of the Building, then Landlord shall, at
its expense, repair or replace any such exterior glass as needed. In addition,
Landlord agrees that it shall at all times, keep the Common Areas in good repair
and condition, reasonable wear and tear excepted, and will promptly make all
repairs thereto which may be necessary during the Term of this Lease. Tenant
agrees that the costs associated with the immediately preceding sentence shall
be included in CAM Charges and paid by Tenant to Landlord as set forth in
Section 4 above and subject to the limitations set forth in Section 4 above. In
addition, subject to the provisions of Exhibit "B" attached hereto, prior to the
date on which Landlord delivers possession of the Premises to Tenant, Landlord
shall test and evaluate the HVAC systems of the Building and cause such HVAC
system to be in good working order prior to such date. Except as specifically
set forth herein, Tenant shall be responsible for all other maintenance, repair
and replacements required to the Premises and in connection with the Premises.
Landlord shall not be liable to Tenant for any damage or inconvenience, and
Tenant shall not be entitled to any abatement or reduction of rent, by reason of
any repairs, alterations or additions made by Landlord under this Lease.


                                       11
<PAGE>   12

         (b)      Other than those items for which Landlord shall be responsible
in accordance with the provisions in Section 9(a) above, Tenant shall, at its
own cost and expense, perform all maintenance, make all repairs, and replace any
and all damages or injury to all or any part of the Premises, in order to keep
the Premises in good, safe and clean condition and repair at all times,
including, but not limited to repairing any damage or injury caused by Tenant or
Tenant's agent, employees, invitees, licensees or visitors; provided, however,
if Tenant fails to make the repairs or replacements within thirty (30) days of
receipt of notice of the need for such repairs or replacements (or such longer
or shorter period as may be reasonable under the circumstances), Landlord may,
at Landlord's option, make the repairs or replacements and Tenant shall
reimburse the actual cost plus fifteen (15%) percent overhead and administrative
to Landlord on demand. Landlord hereby grants Tenant the license to have access
to the roof of the Building solely for purposes of Tenant repairing, maintaining
and replacing the air conditioning units serving the Premises, provided that
Tenant shall be responsible for repairing any damage to the roof caused by
Tenant or Tenant's employees, officers, servants, agents, contractors,
subcontractors, assignees, sublessees, licensees or invitees or persons employed
by any of them, and provided further that Tenant shall not cause or permit any
act to occur which would invalidate any roof warranty or bond.

         (c)      Tenant shall not commit or allow any waste or damage to be
committed on any portion of the Premises, and at the termination of this Lease,
by lapse of time or otherwise, Tenant shall deliver the Premises to Landlord in
as good condition as at the date of first possession of Tenant, only ordinary
wear and tear excepted. The actual cost and expense plus fifteen (15%) percent
overhead and administrative of any repairs necessary to restore the condition of
the Premises shall be borne by Tenant, and if Landlord undertakes to restore the
Premises, it shall have the right of reimbursement against Tenant.

         (d)      Throughout the Term of this Lease, Tenant shall be responsible
for, among other items, the repairing or replacement of all fixtures installed
by Tenant, windows (other than any exterior glass for which Landlord shall be
responsible in accordance with the provisions in Section 9(a) above), glass
(other than any exterior glass for which Landlord shall be responsible in
accordance with the provisions in Section 9(a) above), plate glass (other than
any exterior glass for which Landlord shall be responsible in accordance with
the provisions in Section 9(a) above), locks, interior walls, floors, preventive
and routine maintenance of and repair/replacement to the heating, ventilating
and air conditioning systems and to the electrical, plumbing and sprinkler
systems serving the Premises. Maintenance made under this subsection shall be
made at Tenant's expense. Said mechanical unit requires periodic filter change
and routine service and adjustments at least four times annually. Tenant agrees
to enter into a preventive maintenance agreement with a service firm reasonably
approved by Landlord to provide said maintenance during the Term of this Lease
and any extensions thereof. A copy of said agreement or contract shall be
supplied to the Landlord within thirty (30) days after occupancy and Tenant is
subject to audit or inspection at all times to determine compliance. Provided
that Tenant shall have fully and strictly complied with its obligations
hereunder, if the compressor, condenser or other major components of the
existing 20-ton or 5-ton air conditioning units servicing the Premises become in
need of repair or replacement during the Term of this Lease, then the first
$1,000 of repair or replacement cost per occurrence in the case of the 20-ton
units and the first $500 in repair or replacement cost per occurrence in the
case of the 5-ton unit shall be paid by Tenant and Landlord, at Landlord's cost
and expense and not as a component of CAM Charges, shall pay the reasonable
repair and/or replacement costs per occurrence in excess thereof, provided that
Landlord's prior written consent of the nature and scope of the repair and
replacement and cost thereof is obtained by Tenant, which consent by Landlord
shall not be unreasonably withheld. Tenant shall further enter into a pest
control maintenance contract with a professional pest control company.


                                       12
<PAGE>   13

         (e)      The following event shall be deemed to be an event of default
by Landlord under this Lease: Landlord shall fail to comply with the covenant
made by Landlord under Section 9(a) above to maintain and repair the roof of the
Building in accordance with the terms and provisions of Section 9(a) of this
Lease and shall not cure such failure within thirty (30) days after receipt by
Landlord and any mortgagee of Landlord of written notice thereof by Tenant;
provided, however, if such default is of a nature that it can be cured and if
Landlord in good faith commences to cure such default within such cure period,
but due to the nature of such default it could not be cured within such cure
period after due diligence, no event of default shall be deemed to have occurred
at the end of the cure period if Landlord is then diligently pursuing such cure
to completion and completes such cure as promptly as reasonably possible under
all of the circumstances. Upon the occurrence of the aforesaid event of default
by Landlord, while the condition which gave rise to the event of default
continues, Tenant shall have the option to perform such obligation which
Landlord has failed to perform, and the actual reasonable amount of the cost and
expense incurred by Tenant to perform such obligation shall be paid by Landlord
to Tenant. Tenant shall provide Landlord with copies of the invoice or other
written evidence of the costs and expenses incurred by Tenant for which Tenant
claims reimbursement. If Landlord shall fail to pay such costs and expenses
within thirty (30) days after written demand therefor, Tenant shall have the
right to deduct the amount due by Landlord to Tenant hereunder as an offset from
Base Rent next due hereunder.

         10.      COMPLIANCE WITH LAWS, RULES AND REGULATIONS.

         Tenant shall comply with all laws, ordinances, orders, rules and
regulations of state, federal, municipal or other agencies or bodies having
jurisdiction relating to the use, condition and occupancy of the Premises.
Landlord represents and warrants that to the best of Landlord's actual
knowledge, Landlord has not received written notice from any applicable
governmental authority that the Premises is in violation of any laws,
ordinances, orders, rules or regulations of state, federal, municipal or other
agencies or bodies having jurisdiction relating to the use, condition and
occupancy thereof. Tenant will comply with the rules of the Building adopted by
Landlord, which are set forth on Exhibit "D" attached to this Lease. Landlord
shall have the right at all times to change the rules and regulations of the
Building or to amend them in any reasonable manner as may be deemed advisable
for the safety, care and cleanliness, and for the preservation of good order, of
the Premises. All changes and amendments in the rules and regulations of the
Building will be sent by Landlord or Tenant in writing and shall thereafter be
carried out and observed by Tenant.

         11.      LANDLORD IMPROVEMENTS.

         Construction is to be done by Landlord on the Premises prior to
Tenant's occupancy pursuant to the terms and provisions of Exhibit "B". Upon
"substantial completion" of the Initial Improvements (as defined in Exhibit
"B"), Tenant agrees to accept delivery of the Premises and to execute and
deliver to Landlord a letter of acceptance accepting delivery of the Premises
(an "Acceptance Letter"). "Substantial Completion" of the Initial Improvements
shall be deemed to occur when the Initial Improvements shall have been
substantially completed, a certificate of occupancy (either temporary or final)
or other governmental permit shall have been issued for the Premises permitting
legal use of the Premises, and there are no punch list item defects in the
Initial Improvements which materially interfere with Tenant's use of the
Premises for the purposes specified in this Lease. Subject to the provisions of
Section 2 above granting Tenant liquidated damages in certain circumstances, if
the Initial Improvements have not been substantially completed on or before
January 1, 2001, Landlord shall not be liable to Tenant in any manner for such
delay. Other than such construction prior to occupancy and other than Landlord's
maintenance obligations set forth in Section 9(a) above, Landlord shall have no
obligation to alter, remodel, improve, repair, decorate or paint the Premises.
By taking possession of the Premises, Tenant


                                       13
<PAGE>   14

accepts the Premises as being in good order, condition and repair, and in the
condition which Landlord is obligated to deliver them to Tenant, except for such
items as Tenant may set forth on in the Acceptance Letter or a punch list to be
provided from Tenant to Landlord in accordance with the Notices provision of
this Lease within thirty (30) days after Landlord's delivery of possession of
the Premises to Tenant. Tenant hereby expressly acknowledges and agrees that no
representations concerning the condition of the Building or the Project have
been made by Landlord to Tenant, except as may be specifically set forth in this
Lease. Landlord shall not be liable for any failure to make any repairs or to
perform any maintenance required of Landlord hereunder, unless such failure
shall persist for an unreasonable period of time after written notice of the
need for such repairs or maintenance is given to Landlord by Tenant in
accordance with the Notices provision of this Lease.

         12.      ALTERATIONS, LIENS.

         The obligations of Landlord and Tenant to perform work and supply
necessary materials and labor to prepare the Premises for occupancy are set
forth in the Tenant Improvement Agreement attached hereto as Exhibit "B" and
incorporated herein. Landlord and Tenant shall respectively expend such funds
and do all acts required of each of them in the Tenant Improvement Agreement.
Other than the matters specified in the Tenant Improvement Agreement, Tenant
shall not make any alterations, additions or improvements in or to the Premises,
nor install or attach fixtures in or to the Premises, without the prior written
consent of Landlord, which consent shall not be unreasonably withheld or denied;
provided, however, that with respect to any alterations, additions or
improvements which affect the structure of the Building, materially adversely
affect any of the Building's systems (e.g., mechanical, electrical or plumbing),
are visible from the exterior of the Building, or do not comply with all laws,
orders, ordinances, directions, requirements, rules and regulations of all
governmental authorities, such consent shall be in Landlord's sole and absolute
discretion. Notwithstanding the foregoing, Landlord's consent shall not be
required (but prior notice from Tenant to Landlord shall be required) for any
proposed minor, interior, non-structural alteration, addition or improvement
which does not affect the structure of the Building, does not materially
adversely affect any of the Building's systems (e.g., mechanical, electrical or
plumbing), does not require the use of materials, finishes or installations
other than Building standard items, is not visible from the common areas or
exterior of the Building, is in full compliance with all laws, orders,
ordinances, directions, requirements, rules and regulations of all governmental
authorities, and does not exceed Fifty Thousand Dollars ($50,000.00) in cost in
the aggregate in each instance. Notwithstanding the foregoing, no such prior
notice to Landlord shall be required for any painting, carpeting and/or purely
decorative changes made to the interior of the Premises, regardless of the cost
thereof. All alterations, additions or improvements made, installed in or
attached to the Premises by Tenant, upon the consent specified above, shall be
made at Tenant's expense in a good and workmanlike manner, in accordance with
the plans and specifications prepared for Tenant by a registered architect and
approved by Landlord, all applicable laws, ordinances, regulations and other
requirements of any appropriate governmental authority, and any applicable
covenants or other restrictions prior to the commencement of any work permitted
in accordance with this Section, Tenant shall deliver to Landlord a certificate
of insurance in favor of Landlord from the contractor or contractors which will
perform the work certifying that insurance coverage reasonably satisfactory to
Landlord is in effect.

         Tenant shall keep the Premises free from all liens, rights to liens or
claims of liens of contractors, subcontractors, mechanics or materialmen for
work done or materials furnished to the Property at the request of Tenant;
whenever and so often as any such lien shall attach or claims therefor shall be
filed against the Property or any part thereof as a result of work done or
materials furnished to the Property at the request of Tenant, Tenant shall,
within thirty (30) days after Tenant has notice of the claim for lien, cause the
same to be discharged of record, which discharge may be accomplished by payment,
deposit or bonding proceedings. If Tenant shall fail to cause such lien to be
discharged within the period aforesaid, then, Tenant shall be in default of its
obligations hereunder and, in addition to any other right or


                                       14
<PAGE>   15

remedy, Landlord may, but shall not be obligated to, discharge the same either
by paying the amount claimed to be due or by procuring the discharge of such
lien by deposit or by bonding proceedings. Any amount so paid by Landlord and
all costs and expenses, including without limitation attorneys' fees, incurred
by Landlord in connection therewith shall constitute Additional Rent payable by
Tenant under this Lease and shall be paid by Tenant in full within ten (10)
business days of demand of Landlord, together with interest at the Default Rate
thereon from the date the same was paid by Landlord as provided herein. Tenant
shall not have the authority to subject the interest or estate of Landlord to
any liens, rights to liens or claims of liens for services, material, supplies
or equipment furnished to Tenant, and all persons contracting with Tenant are
hereby charged with notice that they must look to Tenant and to Tenant's
interest only to secure payment.

         Except for items which are easily removable, or which can be removed
but require remediation of the Premises which Tenant agrees to perform at
Tenant's cost and expense, all alterations, additions or improvements,
including, but not limited to, fixtures, partitions, counters and window and
floor coverings, which may be made or installed by either of the parties hereto
upon the Premises, irrespective of the manner of annexation, and irrespective of
which party may have paid the cost thereof, shall be the property of Landlord,
and shall remain upon and be surrendered with the Premises as a part thereof at
the termination of this Lease, without disturbance, molestation or injury;
provided, however, Tenant shall have the right to remove from the Premises
movable office furniture, movable partitions, data processing and related
equipment and improvements put in at the expense of Tenant, but only if such
furniture, equipment and improvements were not constructed or installed as part
of the "Initial Improvements" pursuant to the Tenant Improvement Agreement or
other written consent by Landlord. Tenant shall, prior to the termination of
this Lease, restore any areas damaged or affected by the removal of any such
furniture, equipment and improvements to the condition existing prior to the
installation of such furniture, equipment and improvements. The parties
acknowledge and agree that any improvements, alteration, additions, equipment or
facilities constructed or installed as part of the "Initial Improvements"
pursuant to the Tenant Improvement Agreement provided herein or other written
consent by Landlord, shall be the property of Landlord and shall remain upon and
be surrendered with the Premises as a part thereof at the termination of this
Lease. Notwithstanding the foregoing, however, upon written notice delivered to
Tenant at the time of Landlord's approval of Tenant's plans and specifications,
Landlord may elect that any or all installations made or installed by or on
behalf of Tenant after the Commencement Date that are non-standard for general
office use be removed at the end of the Lease Term and, if Landlord so elects,
Tenant shall restore the Premises to the condition they were in previous to such
alterations, additions, improvements, partitions and fixtures on or before the
termination of this Lease, reasonable wear and tear excepted. Such removal and
restoration shall be at the sole expense of Tenant. Further, notwithstanding
anything herein contained, Landlord shall be under no obligation to insure such
alterations, additions, improvements, partitions and fixtures or anything in the
nature of a leasehold improvement made or installed by or on behalf of Tenant,
and all property of Tenant, Tenant's agents, servants, employees, invitees,
licensees, contractors, subcontractors or any other person, shall be on the
Premises at the risk of Tenant only, and Landlord, shall not be responsible for
any damage, destruction, or theft thereof.

         13.      CONDEMNATION.

         In the event any material portion of the Building or substantially all
of the parking available for use by Tenant, or all of the means of ingress and
egress to the Building, shall be taken by condemnation or the exercise of the
right of eminent domain, or if in lieu of any formal condemnation proceedings or
actions, if any, Landlord shall sell any material portion thereof, to the
governmental or other public


                                       15
<PAGE>   16

authority, agency, body or public utility, seeking to take said land, thereby
rendering the Premises unsuitable for the continuation of Tenant's business
operations therein, as determined by Landlord or Tenant in either of their
reasonable discretion, then either party, at its option, may terminate this
Lease upon ten (10) days' prior written notice to the other, provided such
notice is delivered within thirty (30) days from the date of possession by the
condemning authority and prepaid rent shall be proportionately refunded from the
date of possession by the condemning authority. All damages awarded for such
taking, or paid as the purchase price for such sale and conveyance in lieu of
formal condemnation proceedings, whether for the fee or the leasehold interest,
shall belong to and be the property of Landlord; provided, however, Tenant shall
have the sole right to reclaim and recover from the condemning authority, but
not from Landlord, such condemnation as may be separately awarded or recoverable
by Tenant in Tenant's own right on account of any and all costs or loss
(including loss of business) to which Tenant might be put in removing Tenant's
merchandise, furniture, fixtures, leasehold improvements and equipment to a new
location. Tenant shall execute and deliver any instruments, at the expense of
Landlord, as Landlord may deem necessary to expedite any condemnation
proceedings or to effectuate a proper transfer of title to such governmental or
other public authority, agency, body or public utility seeking to take or
acquire the said lands and Premises or any portion thereof. Tenant shall vacate
the Premises, remove all Tenant's personal property therefrom and deliver up
peaceable possession thereof to Landlord or to such other party designated by
Landlord in the aforementioned notice. Failure by Tenant to comply with any
provisions of this Section shall subject Tenant to such costs, expenses, damages
and losses as Landlord may incur by reason of Tenant's breach hereof. If neither
party chooses to terminate this Lease, then to the extent and availability of
condemnation proceeds received by Landlord and subject to the rights of any
mortgagee thereto, Landlord shall at the sole cost and expense of Landlord and
with due diligence and in good and workmanlike manner, restore and reconstruct
the Premises (including the Initial Improvements) within a period of one hundred
eighty (180) working days after the date of the physical taking, and such
restoration and reconstruction shall make the same reasonable tenantable and
suitable for the general use being made by Tenant prior to the taking; provided,
however, that Landlord shall have no obligation to restore and reconstruct
Tenant's leasehold improvements (other than the Initial Improvements) unless and
to the extent that Landlord receives an award of condemnation proceeds
specifically designated as compensation for such improvements and receives any
mortgagees consent to do so. Notwithstanding the foregoing, if Landlord has not
completed such restoration and reconstruction on or before one hundred eighty
(180) working days after the date of physical taking, Tenant, in addition to any
other rights and remedies Tenant may have, shall have the right to cancel this
Lease. If this Lease continues in effect after such physical taking, the rent
which is payable hereunder shall be equitably adjusted both during the period of
restoration and reconstruction operations of Landlord and during the unexpired
portion of the Lease Term.

         In the event Landlord, during the Lease Term, shall be required by any
governmental authority or the order of decree of any court, to repair, alter,
remove, reconstruct or improve any part of the Premises, other than those
repairs, alterations or improvements required as a result of Tenant's use,
occupancy and operation at the Premises, then such repairs, alterations,
removal, reconstruction or improvement may be made by and at the expense of
Landlord and shall not in any way affect the obligations or covenants of Tenant
herein contained, and Tenant hereby waives all claims for damages or abatement
of rent because of such repairs, alterations, removal, reconstruction or
improvement, except that rent shall abate during the period of and to the extent
of untenantability; provided, if the repairs, alterations, removal,
reconstruction or improvement required, ordered or decreed shall render the
Premises untenantable, then unless said repairs, alteration, removal,
reconstruction or improvement is completed within one hundred eighty (180)
working days after the date of the notice, requirement, order or decree, either
party hereto upon written notice to the other party given not later than two
hundred ten (210) working days after the date of said notice, requirement, order
or decree, may terminate this Lease, in which case rent shall be apportioned and
paid to the date the Premises were rendered untenantable;


                                       16
<PAGE>   17

provided however that where the requirement by a governmental authority having
jurisdiction to repair, alter, remove, reconstruct or improve any part of the
Premises arises out of any act of omission or commission by Tenant, or out of
Tenant's specific use of the Premises, then such repair, alteration, removal,
reconstruction of improvement shall be effected promptly at the sole cost and
expense of Tenant and there shall not, in any event, be any abatement of rent
nor any right in Tenant to terminate this Lease whether or not the completion of
such repair, alteration, removal, reconstruction or improvement takes more than
one hundred eighty (180) working days.

         14.      FIRE AND CASUALTY.

         (a)      If the Premises shall be partially or totally damaged or
destroyed by fire or other casualty, then whether or not the damage or
destruction shall have resulted from the fault or neglect of Tenant, or its
employees, agents or visitors, and if this Lease shall not have been terminated
as in this Section 14 hereinafter provided, then Landlord shall repair the
damage and restore and rebuild the Premises, without limiting the rights of
Landlord under any other provisions of this Lease, with reasonable dispatch
after notice to it of the damage or destruction; provided, however, that
Landlord shall not be required to repair or replace any of Tenant's personal
property or any leasehold improvements made after the Commencement Date.

         (b)      If the Premises shall be partially damaged or partially
destroyed by fire or other casualty, then whether or not such fire or damage
shall have resulted from the negligence of Tenant, the rents payable hereunder
shall be abated to the extent that the Premises shall have been rendered
untenantable and are in fact not occupied by Tenant for the period from the date
of such damage or destruction to the date the damage shall be repaired or
restored. If the Premises or a major part thereof shall be totally (which shall
be deemed to include substantially totally) damaged or destroyed and rendered
completely (which shall be deemed to include substantially completely)
untenantable on account of fire or other casualty, the rents shall abate as of
the date of the damage or destruction and until Landlord shall repair, restore
and rebuild the Building and the Premises; provided, however, that should Tenant
reoccupy a portion of the Premises during the period the restoration work is
taking place and prior to the date that the same are made in all material
respects tenantable, rents allocable to such portion shall be payable by Tenant
from the date of such occupancy.

         (c)      If the Premises shall be totally damaged or destroyed by fire
or other casualty, or if the Premises shall be so damaged or destroyed by fire
or other casualty as to require a reasonably estimated expenditure of more than
forty percent (40%) of the full insurable value of the Building immediately
prior to the casualty, or if there shall be damage to the Premises resulting
from a risk other than an insured risk to an extent greater than twenty-five
percent (25%) of the replacement cost of the Premises above the foundation, then
in any such case Landlord may terminate this Lease by giving Tenant notice to
such effect within ninety (90) days after the date of the casualty. In case of
any damage or destruction mentioned in this Section 14, if Landlord has not
substantially completed the making of the required repairs and restored and
rebuilt the Premises and access thereto for any reason other than Force Majeure
Delay or Tenant Delay within three hundred sixty-five (365) days from the date
of the commencement of the restoration work, then Tenant may terminate this
Lease upon not less than thirty (30) days' written notice to Landlord given at
any time prior to substantial completion of the restoration work; provided,
however, in the event Landlord substantially completes the repairs and
restoration of the Premises and access thereto within the thirty (30) day period
following Landlord's receipt of Tenant's written notice electing to terminate
this Lease, Tenant's termination notice shall be void and of no force or effect
and this Lease shall continue in full force and effect for the remainder of the
Term, unless earlier terminated pursuant to any other provision of this Lease.
In the case of any damage or destruction to the Premises occurring during the
last twelve (12) months of the Term of this Lease, either Landlord or Tenant may


                                       17
<PAGE>   18

terminate this Lease by written notice to the other if Landlord reasonably
estimates that more than sixty (60) days shall be required to substantially
complete the making of the required repairs and restore and rebuild the
Premises.

         (d)      In the case of any damage or destruction mentioned in Section
14, Landlord, within sixty (60) days after such damage or destruction, or within
such longer period as may be reasonably required, shall deliver to Tenant an
estimate (the "Estimate") of the time (the "Estimated Time") required to repair
or restore the damage or destruction, prepared by an independent contractor or
architect selected by Landlord. In addition to Tenant's rights to terminate this
Lease as provided in Section 14(c), if the Estimated Time set forth in the
Estimate exceeds three hundred sixty-five (365) days from the date of the
Estimate, Tenant may terminate this Lease by notice to Landlord delivered by
Tenant within ten (10) days after Tenant's receipt of the Estimate.

         (e)      No damages, compensation or claim shall be payable by Landlord
for inconvenience, loss of business, annoyance or otherwise arising from any
repair or restoration of any portion of the Premises pursuant to this Section
14(c) above.

         (f)      Landlord will not carry separate insurance of any kind on
Tenant's property or improvements constructed after the Commencement Date, and
shall not be obligated to repair any damage thereto or replace the same. Tenant
shall maintain insurance on Tenant's property and on any improvements made after
the Commencement Date, and Landlord shall not be obligated to repair any damage
thereto or replace the same.

         (g)      Landlord and Tenant shall each look first to any insurance in
its favor before making any claim against the other party for recovery for loss
or damage resulting from fire or other casualty.

         (h)      Landlord agrees to include in its fire insurance policies
appropriate clauses pursuant to which the insurance companies (i) waive all
right of subrogation against Tenant with respect to losses payable under such
policies and/or (ii) agree that such policies shall not be invalidated should
the insured waive in writing prior to a loss any or all right of recovery
against any party for losses covered by such policies. Tenant agrees to include
in its fire insurance policy or policies on its furniture, furnishings, fixtures
and other property removable by Tenant under the provisions of this Lease
appropriate clauses pursuant to which the insurance company or companies (i)
waive the right of subrogation against Landlord with respect to losses payable
under such policy or policies, and/or (ii) agree that such policy or policies
shall not be invalidated should the insured waive in writing prior to a loss any
or all right of recovery against any party for losses covered by such policy or
policies. Provided that Landlord's right of full recovery under its policy or
policies aforesaid is not adversely affected or prejudiced thereby, Landlord
hereby waives any and all right of recovery which it might otherwise have
against Tenant, its servants, agents and employees, for loss or damage occurring
to the Building and the fixtures, appurtenances and equipment therein, to the
extent the same is covered by Landlord's insurance, notwithstanding that such
loss or damage may result from the negligence or fault of Tenant, its servants,
agents or employees. Provided that Tenant's right of full recovery under its
aforesaid policy or policies is not adversely affected or prejudiced thereby,
Tenant hereby waives any and all right of recovery which it might otherwise have
against Landlord, its servants, agents and employees, for loss or damage to
Tenant's furniture, furnishings, fixtures and other property removable by Tenant
under the provisions hereof to the extent that same is covered by Tenant's
insurance, or would have been covered by Tenant's insurance had Tenant complied
with Tenant's insurance obligations under this Lease, notwithstanding that such
loss or damage may result from the negligence or fault of Landlord, its
servants, agents or employees, or such other tenant and the servants, agents or
employees thereof. Landlord and Tenant hereby agree to advise the other promptly
if the clauses to be included in their respective insurance policies pursuant to
this


                                       18
<PAGE>   19

Section 14 cannot be obtained. Landlord and Tenant hereby also agree to notify
the other promptly of any cancellation or change of the terms of any such policy
which would affect such clauses.

         15.      INSURANCE.

         (a)      Throughout the Lease Term, or any extension thereof, Landlord
will insure the Building (excluding foundations and excavations) and the
machinery and equipment contained therein owned by Landlord (excluding any
property with respect to which Tenant is obliged to insure) against damage by
fire, explosion and extended coverage, and other risks customarily insured
against by owners of comparable office parks in the Atlanta, Georgia,
metropolitan area. Landlord may, but shall not be obligated to, take out and
carry any other form or forms of insurance as it or its mortgagee may determine
advisable.

         (b)      Tenant shall comply with all insurance regulations, and after
Tenant has been notified of same nothing shall be done or kept in or on the
Premises by Tenant which will cause cancellation of any such insurance. If any
insurance policy upon the Premises or the Project or any part thereof shall be
canceled or shall be threatened by the insurer to be canceled, the coverage
thereunder reduced or threatened to be reduced or the cost thereof increased or
threatened to be increased in any way by the insurer by reason of the use and
occupation of the Premises by Tenant or by any assignee or subtenant of Tenant,
other than in strict conformity with this Lease, the bringing onto or within the
Building of any flammable, noxious or otherwise dangerous substance by Tenant or
the conduct of any other activity in or about the Premises which in any way
increases the hazard or risk beyond that for which the insurance was written and
for the uses herein provided for, and if Tenant fails to remedy the condition
giving rise to such cancellation, reduction on cost increase or threat thereof
within five (5) business days after written notice thereof by Landlord, Landlord
may, at its option, do any one of the following:

         (i)      Declare a default by Tenant, and thereupon the provisions of
         this Lease with respect thereto shall apply; or

         (ii)     If the sole action taken by such insurer is to raise the
         premium or other monetary cost of such insurance, demand payment from
         Tenant of such amount of the increase in the premium or other cost
         (over the previous base amount) as Additional Rent hereunder, and if
         Tenant fails to make payment of same to Landlord within thirty (30)
         days of such demand by Landlord in writing, Landlord may declare a
         default by Tenant and thereupon the provisions of this lease with
         respect thereto shall apply. Notwithstanding any contribution by Tenant
         to the cost of insurance premiums, as provided herein, Tenant
         acknowledges that it has no right to receive any proceeds from any such
         insurance policies carried by Landlord and that such insurance will be
         for the sole benefit of Landlord with no coverage for Tenant for any
         risk insured against.

         (c)      Tenant shall, during its occupancy of the Premises and during
the entire Lease Term, at its sole cost and expense, obtain, maintain and keep
in full force and effect, and with Tenant, Landlord and Landlord's mortgagees
named as additional insured therein as their respective interests may appear,
the following types and kinds of insurance:

         (i)      Property Insurance upon property of every description and kind
         owned by Tenant and located in the Building or for which Tenant is
         legally liable or installed by or on behalf or Tenant, including,
         without limitation, furniture, fittings, installations, alteration,
         additions, partitions and fixtures, in an amount not less than one
         hundred percent (100%) of the full replacement cost thereof; and in the
         event that there shall be a dispute as to the amount which comprise
         full replacement cost, the decision of Landlord shall be conclusive.


                                       19
<PAGE>   20

         (ii)     Commercial general liability insurance in an amount not less
         than $1,000,000.00 for any one occurrence or such higher limits as
         Landlord may reasonably require from time to time; such insurance shall
         include coverage for "Fire Legal" liability (coverage against damage to
         the property of any other tenant of the Building for which Tenant would
         be liable) with respect to the Premises.

         (iii)    Worker's compensation insurance in the amount required by law
         to protect Tenant's employees.

         (iv)     Any other form or forms of insurance as Tenant or Landlord may
         reasonably require from time to time, in form, in amounts and for
         insurance risks against which a prudent tenant would protect itself,
         provided such additional coverage is appropriate, customary and
         generally required for like premises utilized for similar purpose in
         the Metropolitan Atlanta area.

         (d)      All insurance policies shall be taken out with companies
licensed and registered to operate in the State of Georgia (or if not licensed
in the State of Georgia, a national company with a Best Rating of no less than
A-) acceptable to Landlord in its reasonable discretion and in form satisfactory
to Landlord in its reasonable discretion. Such insurance may be by blanket
insurance policy or policies. Tenant shall deliver certificates evidencing such
insurance policies, and any endorsement, rider or renewal thereof, to Landlord;
certificates evidencing renewals shall be delivered to Landlord no later than
fifteen (15) days after each renewal, as often as renewal occurs, and in no
event less than fifteen (15) days prior to the date on which the policy would
otherwise expire. All such insurance policies shall require said insurance
companies to notify Landlord and Landlord's mortgagees in writing thirty (30)
days prior to any material change, cancellation or sooner termination thereof.
In addition to the foregoing, if Tenant performs any work on the Premises, prior
to the commencement of any such work, Tenant shall deliver to Landlord
certificates issued by insurance companies licensed and registered to operate in
the State of Georgia, evidencing that workers' compensation insurance, public
liability insurance and property damage insurance, all in amounts reasonably
satisfactory to Landlord, are in force and effect and maintained by all
contractors and subcontractors engaged by Tenant to perform such work. Landlord
agrees to act reasonably and in good faith with respect to the decisions
required of Landlord under this Section 15. The reasonableness of any consent or
approval (or denial thereof) or of the exercise of Landlord's discretion shall
be determined in accordance with generally accepted management, leasing, and
operating practices for similar tenants in similar office buildings in the
Metropolitan Atlanta area. The parties hereto intend that such reasonableness
standard shall be implemented on an objective standard, instead of a subjective
one, and such concept of reasonableness does not include or comprehend arbitrary
or capricious reasons or considerations based on such factors such as pecuniary
gain or mere personal preferences.

         16.      WAIVER OF SUBROGATION.

         Anything in this Lease to the contrary notwithstanding, Landlord and
Tenant hereby waive and release each other of and from any and all rights of
recovery, claim, action or cause of action, against each other, their agents,
officers and employees, for any loss or damage that may occur to the Premises,
improvements to the Building, or personal property (building contents) within
the Building or the Project, by reason of fire, the elements or any other cause
which could be insured against under the terms of standard fire and extended
coverage insurance policies, regardless of cause of origin, including


                                       20
<PAGE>   21

negligence of Landlord or Tenant and their agents, officers and employees.
Because this Section will preclude the assignment of any claim mentioned in it
by way of subrogation (or otherwise) to an insurance company (or any other
person), each party to this Lease agrees immediately to give to each insurance
company which has issued to it policies of fire and extended coverage insurance,
written notice of the terms of the mutual waivers contained in this Section, and
to have the insurance policies properly endorsed, if necessary, to prevent the
invalidation of the insurance coverages by reason of the mutual waivers
contained in this Section.

         17.      INDEMNIFICATION.

         (a)      Subject to the provisions of Sections 14(h) and 16 above, and
notwithstanding that joint or concurrent liability may be imposed upon Landlord
by law, Tenant shall indemnify, defend and hold harmless Landlord and the
Project, at Tenant's expense, against (i) any default by Tenant or permitted
subtenant hereunder; (ii) any negligence or wilful misconduct of Tenant or its
agents, contractors, employees, invitees or licensees; and (iii) all claims for
damages to persons or property by reason of the use or occupancy of the Premises
not caused by Landlord. Moreover, Landlord shall not be liable for any damage or
injury to the Premises, to Tenant's property, to Tenant, its agents,
contractors, employees, invitees or licensees, arising from any use or
conditions of the Premises, or any sidewalks or entrance ways serving the
Premises, or the act or neglect of co-tenants or any other person, or the
malfunction of any equipment or apparatus serving the Premises, or any loss
thereof by mysterious disappearance or otherwise. Any and all claims against
Landlord for any damage referred to in this Section are hereby waived and
released by Tenant, unless arising from the gross negligence or wilful
misconduct of Landlord.

         (b)      Subject to the provisions of Sections 14(h) and16 above,
Landlord shall indemnify, defend and hold harmless Tenant, at Landlord's
expense, against any and all claims, losses, liability, expenses or attorneys'
fees for any injury or death to any person or damage to property caused by the
negligence or willful misconduct Landlord or its agents, contractors, employees
or licensees (but excepting those resulting from the negligence of Tenant, its
agents, contractors, employees, invitees, licensees, subtenants, and assignees)
occurring in the common areas of the Project or in the Premises, but only to the
extent of the proceeds actually received by Landlord from Landlord's commercial
general liability insurance with respect to the Project. The indemnity, defense
and hold harmless agreement in the preceding sentence shall not be applicable to
any such liability, loss, cost, damage or expense imposed on Tenant by any
employee, partner, agent, or contractor of Tenant unless such liability, loss,
cost, damage, or expense was caused by the willful misconduct or negligence of
Landlord or any of its agents, servants, employees, contractors or
representatives acting within the scope of their agency, employment, contract or
representation and not from the negligence of Tenant, its employees,
contractors, servants, agents, representatives, invitees, subtenants, and
assignees.

         18.      QUIET ENJOYMENT.

         Landlord warrants that it has full right to execute and to perform this
Lease and that Tenant, upon payment of the required rents and performing the
terms, conditions, covenants and agreements contained in this Lease, and so long
as no default occurs and continues beyond any applicable grace periods, shall
peaceably and quietly have, hold and enjoy the Premises during the full Term of
this Lease as well as any extension or renewal without hindrance by Landlord or
its agents, subject to other provisions of this Lease; provided, however, that,
subject to the provisions of Section 28 below, Tenant accepts this Lease subject
and subordinate to any recorded deed to secure debt, mortgage, deed of trust or
other lien presently existing upon the Premises and to any deed to secure debt,
mortgage, deed of trust or other lien hereafter placed on the Premises, and
Tenant agrees upon demand to execute additional instruments subordinating this
Lease as Landlord may reasonably require.


                                       21
<PAGE>   22

         19.      LANDLORD'S RIGHT OF ENTRY.

         Landlord shall have the right, at all reasonable hours, provided
Landlord gives Tenant reasonable prior notice and gives Tenant the opportunity
to have a representative of Tenant present (except in the event of an
emergency), to enter the Premises for the following: emergency inspection;
making repairs as Landlord may deem necessary or desirable; determining Tenant's
use of the Premises; or determining if an act of default under this Lease has
occurred or upon the occurrence of a default; or to exhibit the Premises to
mortgagees, prospective mortgagees and prospective purchasers; or to exhibit the
Premises to prospective tenants during the last nine (9) months of the Lease
Term or at any other time that Tenant is in default hereunder beyond applicable
notice and cure periods. During such time as work is being performed in or about
the Premises, payments provided herein shall not abate and Tenant waives any
claim or cause of action against Landlord by reason of interruption of Tenant's
business or loss of profits resulting therefrom, provided that Landlord shall
use reasonable efforts not to materially interfere with Tenant's daily operation
of its business in the Premises. Notwithstanding the foregoing, subject to the
provisions below, Tenant shall be permitted to install locks or other access
control devices for high security areas in the Premises (such areas designated
by Tenant in writing to Landlord are herein referred to as the "Secured Areas"),
and Tenant shall not be required to furnish Landlord with a duplicate set of
keys or access control devices to the Secured Areas (unless Landlord is required
by law to have keys or other means of access to such Secure Areas), and Landlord
shall not be permitted to enter the Secured Areas (i) unless with the prior
written consent of Tenant, which consent Tenant shall not unreasonably withhold
or delay, or (ii) except in the case of an emergency. The Secured Areas shall
not constitute more than ten percent (10%) of the total rentable area of the
Premises and shall not eliminate access to the portion of the Premises which is
not a Secured Area. To the extent Landlord is otherwise obligated to do so
pursuant to this Lease, Landlord shall not be required to perform any service to
any Secured Area to which Landlord does not have access and for which access is
necessary for the provision of such service. The Secured Areas shall not prevent
access to the roof of the Building.

         20.      ASSIGNMENT OR SUBLEASE.

         Tenant shall not assign this Lease, or any interest herein, or
mortgage, pledge, encumber, hypothecate or otherwise transfer or sublet or allow
any other person, firm or corporation to use or occupy the Premises, or any part
thereof, without the prior written consent of Landlord, which consent shall not
be unreasonably withheld or denied; provided however that Landlord shall have
the right to apply such tests and make such investigations as it deems
reasonable and necessary in determining the acceptability of any proposed
assignee or subtenant, and without limiting the generality of the foregoing,
such tests may include the financial background and business history; provided
further that Tenant shall provide to Landlord such information as Landlord may
reasonably require to enable it to determine the acceptability of the proposed
assignee or subtenant, including information concerning all of the foregoing
matters, and Landlord shall have no obligation to consent to any assignment or
subletting unless it has received from Tenant (at no cost or expense to
Landlord) the most recent financial statements (audited if and to the extent
available) of the proposed assignee or subtenant and such other information as
Landlord reasonably requires (all of the foregoing information is herein
sometimes collectively referred to as the "Proposed Transfer Information"). It
shall be reasonable for Landlord to withhold its consent to any assignment or
sublease if (i) Tenant is in default under this Lease beyond any applicable
notice and cure period, (ii) the proposed assignee or sublessee is a tenant in
the Project and Landlord can accommodate such tenant's space needs in the
Project, (iii) the financial responsibility, nature of business, and character
of the proposed assignee or subtenant are not all reasonably satisfactory to
Landlord, it being agreed that the net worth and credit rating of Tenant shall
be taken into account by Landlord in its review of the financial responsibility
of the proposed assignee or subtenant, (iv) in the reasonable judgment of
Landlord the purpose for which the assignee or subtenant intends to use the
Premises (or a portion thereof) is not in keeping with Landlord's standards for
the Building or are in violation of the terms of this Lease or any


                                       22
<PAGE>   23

other leases in the Project, (v) the proposed assignee or subtenant is a
governmental entity, or (vi) the proposed assignment (as opposed to a sublease)
is for less than the entire Premises or for less than the remaining Term of this
Lease. The foregoing shall not exclude any other reasonable basis for Landlord
to withhold its consent. In the event Landlord fails to approve or disapprove
any such sublease or assignment request within twenty (20) days after Landlord's
receipt of all Proposed Transfer Information from Tenant, such sublease or
assignment shall be deemed to be approved. If Tenant is a corporation, any
dissolution, merger, consolidation or other reorganization of Tenant, or the
sale or transfer of a controlling interest in the capital stock of Tenant,
whether in a single transaction or in a series of transactions, shall be deemed
a voluntary assignment of this Lease and subject to the foregoing provisions,
except that the transfer of the outstanding capital stock of any corporate
tenant (including Serologicals Corporation) shall not be deemed to include the
sale of such stock by persons or parties through the "over-the-counter market"
(i.e., Nasdaq) or through the New York Stock Exchange. No assignment or
subletting (with or without the consent of Landlord or as permitted as provided
below) shall release Tenant from its obligations under this Lease nor shall
Tenant permit this Lease or any interest herein or in the tenancy hereby created
to become vested in or owned by any other person, firm or corporation by
operation of law or otherwise. The power of Landlord to give or withhold its
consent to any assignment or subletting shall not be exhausted by the exercise
thereof on one or more occasions, but the same shall be a continuing right and
power with respect to any type of transfer, assignment or subletting. Consent to
one or more such transfers or subleases shall not destroy or waive this
provision, and all subsequent transfers and subleases shall likewise be made
only upon obtaining the prior written consent of Landlord. No assignment of this
Lease consented to by Landlord shall be effective unless and until Landlord
shall receive an original assignment and assumption agreement, in form and
substance satisfactory to Landlord in its reasonable discretion, signed by
Tenant and Tenant's proposed assignee, whereby the assignee assumes due
performance of this Lease to be done and performed for the balance of the then
remaining Lease Term of this Lease. No subletting of the Premises, or any part
thereof, shall be effective unless and until there shall have been delivered to
Landlord an agreement, in form and substance satisfactory to Landlord in its
reasonable discretion, signed by Tenant and the proposed sublessee, whereby the
sublessee acknowledges the right of Landlord to continue or terminate any
sublease, in Landlord's sole discretion, upon termination of this Lease, and
such sublessee agrees to recognize and attorn to Landlord in the event that
Landlord elects under such circumstances to continue such sublease.

         Provided Tenant is not in default under this Lease beyond any
applicable notice and cure period, and subject to the terms and conditions
contained herein, Tenant shall have the right, upon at least five (5) days'
prior written notice to Landlord, to sublease any portion of the Premises to an
Affiliate (defined below) and to assign this Lease to an Affiliate having a
demonstrated net worth determined in accordance with generally accepted
accounting principles and credit rating which is equal to or greater than the
demonstrated net worth determined in accordance with generally accepted
accounting principles and credit rating of Tenant on the date of execution
hereof, without Landlord's consent. The term "Affiliate" as used herein shall
mean (i) any person or entity controlling, controlled by or under common control
with Tenant, or (ii) any corporation or other entity in which or with which
Tenant is merged or consolidated, or (iii) any person or entity which acquires
all or substantially all of the assets or stock of Tenant. The term "control"
shall mean the power directly or indirectly, by contract or otherwise, to direct
the management and policies of the applicable entity. Provided, however, (i) no
assignment or subletting shall relieve Tenant of any of its obligations and
liabilities to Landlord under this Lease (as same may be amended, modified,
assigned, extended or renewed) and Tenant shall remain fully liable for the
faithful performance of all covenants, terms and conditions of this Lease (as
same may be amended, modified, assigned, extended or renewed) on the part of
Tenant to be performed, (ii) such Affiliate of Tenant must be capable of
fulfilling the obligations of Tenant under this Lease (as same may be amended,
modified, assigned, extended or renewed), (iii) it must be demonstrated by
Tenant to Landlord's reasonable satisfaction that such merger, consolidation, or
transfer is being consummated for a valid business purpose, and not principally
for the purpose of transferring Tenant's interest in this Lease, and (iv) such


                                       23
<PAGE>   24

Affiliate of Tenant must execute an assignment and assumption agreement
reasonably acceptable to Landlord. Any such assignment agreement shall provide
that the assignee has assumed all of Tenant's obligations, liabilities and
agreements under this Lease and that this Lease may not be further assigned
without the prior written consent of Landlord, except as otherwise expressly
permitted by this Section 20.

         Seventy-five percent (75%) of any consideration (net of Tenant's
Transfer Costs, as defined below) in excess of the Base Rent and other charges
and sums due and payable by Tenant under this Lease, paid to Tenant by any
assignee of this Lease for its assignment, or by any sublessee under or in
connection with its sublease, or otherwise paid to Tenant by another party for
use and occupancy of the Premises or any portion thereof (any such excess amount
being herein called the "Transfer Profit"), shall be promptly remitted by Tenant
to Landlord as Additional Rent hereunder and Tenant shall have no right or claim
thereto as against Landlord. Landlord may require that any such Transfer Profit
paid by a subtenant or assignee be paid directly to Landlord as Additional Rent
as and when such sums are received. "Tenant's Transfer Costs" means the
outstanding balance from time to time of the sum of the following items: (1) the
reasonable cost of any additional tenant improvements required for the
assignment of this Lease or the subleasing of such portion of the Premises paid
by Tenant; (2) reasonable leasing commissions paid by Tenant in connection with
the assignment or sublease to the transferee, not to exceed the amount of such
commissions customarily payable with respect to the leasing of second-generation
office space in the metropolitan Atlanta area; (3) rent abatements and other
reasonable concessions granted by Tenant in connection with such assignment or
sublease; (4) reasonable marketing expenses paid directly by Tenant to assign
this Lease or sublease the space (to the extent not included in a brokerage
commission paid by Tenant); and (5) reasonable attorneys' fees incurred by
Tenant in connection with such assignment or sublease.

         If Tenant shall make any assignment of this Lease or shall make any
subletting hereunder in any way not authorized by the terms hereof, the
acceptance by Landlord of any rent from any person claiming as assignee,
subtenant or otherwise shall not be construed as a recognition of or consent to
such assignment or subletting or as a waiver of the right of Landlord thereafter
to collect any rent from Tenant, it being acknowledged that Landlord may at any
time accept rent under this Lease from any person offering to pay the same
without thereby acknowledging the person so paying as a Tenant in place of
Tenant hereinabove named, and without releasing said Tenant from the obligations
of this Lease, and without recognizing the claims under which such person offers
to pay said rent, but the same shall be taken to be a payment on account by
Tenant. In the event Landlord consents to an assignment or sublease, Tenant
shall pay to Landlord a fee to cover Landlord's accounting costs plus any
reasonable legal fees actually incurred by Landlord (at such attorneys' normal
and customary hourly rates) as a result of the assignment or sublease.

         Either Landlord or Tenant may require that any dispute of any matter
described pursuant to this Section 20 above be submitted to arbitration pursuant
to this paragraph. All arbitrations shall occur at a location in Atlanta,
Georgia, chosen by the arbitrators and shall be conducted pursuant to the rules
of the American Arbitration Association (or the successor organization, or if no
such organization exists, then from persons of similar professional
qualifications). The party desiring such arbitration shall give written notice
to that effect to the other party and simultaneously therewith also shall give
written notice to the American Arbitration Association, requesting such
organization to select, as soon as possible but in any event within the next ten
(10) days, three arbitrators who are unaffiliated with Landlord and Tenant with,
if reasonably possible, recognized expertise in the subject matter of the
arbitration and at least ten (10)


                                       24
<PAGE>   25

years experience in commercial real estate in Atlanta, Georgia in any capacity,
including without limitation as an attorney, broker, accountant, commercial
property owner or property management agent. Within three (3) working days after
the appointment of the arbitrators, each party shall have the right to object to
the appointment of one (1) of the arbitrators, which objection can only be based
on such arbitrator's failure to meet the selection criteria set forth above, and
to require that the American Arbitration Association select a substitute
arbitrator within five (5) days of such notice of objection to the American
Arbitration Association. Within ten (10) days after the original appointment,
the arbitrators so chosen shall hold a hearing at which each party may submit
evidence, be heard and cross-examine witnesses, with each party having at least
five (5) days advance notice of the hearing. The hearing shall be conducted such
that each of Landlord and Tenant shall have reasonably adequate time to present
oral evidence or argument, but either party may present whatever written
evidence its deems appropriate prior to the hearing (with copies thereof being
sent to the other party). In the event of the failure, refusal or inability of
any arbitrator to act, a new arbitrator shall be appointed in his stead, which
appointment shall be made in the same manner as hereinabove provided. The
decision of the arbitrators so chosen shall be given within a period of ten (10)
days after the conclusion of such hearing, and shall be accompanied by
conclusions of law and findings of fact. The decision in which any two
arbitrators so appointed and acting hereunder concur shall in all cases be
binding and conclusive upon the parties and shall be the basis for a judgment
entered in any court of competent jurisdiction. The fees and expenses of the
arbitration under this paragraph shall be borne equally by both parties;
provided, however, in the event the arbitrators conclude that Landlord withheld
its consent to a proposed assignment or subletting in bad faith (as opposed to a
conclusion that such consent was unreasonably withheld but made in good faith),
Landlord shall pay such fees and expenses. Landlord and Tenant may at any time
by mutual written agreement discontinue arbitration proceedings and themselves
agree upon any such matter submitted to arbitration. Tenant agrees that if
Tenant shall request Landlord's consent under this Lease and Landlord shall fail
or refuse to give such consent, Tenant shall not be entitled to any damages for
the withholding of its consent, it being intended that Tenant's sole remedy
shall be an action for specific performance or injunction and that such remedy
shall be available only in those cases where Landlord has expressly agreed in
writing not to unreasonably withhold its consent or where, as a matter of law,
Landlord may not unreasonably withhold its consent.

         21.      RECAPTURE UPON ABANDONMENT.

         In the event Tenant shall desert, vacate or not use on a regular or
consistent basis, any substantial portion of the Premises for a period of
twenty-four (24) or more consecutive months even though Tenant shall pay
stipulated Base Rent and Additional Rent, Landlord shall have the right, but not
the obligation to terminate this Lease, without declaring a default hereunder,
and recapture the Premises from Tenant upon not less than thirty (30) days'
written notice to Tenant, whereupon Tenant shall peacefully vacate and surrender
possession of the Premises as if the Term of this Lease had expired by its own
terms.

         22.      HAZARDOUS SUBSTANCES.

         Tenant hereby covenants and agrees that Tenant shall not cause or
permit any "Hazardous Substances" (as hereinafter defined) to be generated,
placed, held, stored, used, located or disposed of at the Project or any part
thereof, except for Hazardous Substances as are commonly and legally used or
stored as a consequence of using the Premises for office and administrative
purposes, but only so long as the quantities thereof do not pose a threat to
public health or to the environment or would necessitate a "response action", as
that term is defined in CERCLA (as hereinafter defined), and so long as Tenant
strictly complies or causes compliance with all applicable governmental rules
and regulations concerning the use, storage, production, transportation and
disposal of such Hazardous Substances. Promptly upon receipt of Landlord's
request, Tenant shall submit to Landlord true and correct copies of any reports
filed by Tenant with any governmental or quasi-governmental authority regarding
the generation, placement,


                                       25
<PAGE>   26

storage, use, treatment or disposal of Hazardous Substances on or about the
Project. For purposes of this Section, "Hazardous Substances" shall mean and
include those elements or compounds which are contained in the list of Hazardous
Substances adopted by the United States Environmental Protection Agency (EPA) or
in any list of toxic pollutants designated by Congress or the EPA or which are
defined as hazardous, toxic, pollutant, infectious (including infectious or
hazardous medical waste) or radioactive by any other federal, state or local
statute, law, ordinance, code, rule, regulation, order or decree regulating,
relating to or imposing liability (including, without limitation, strict
liability) or standards of conduct concerning, any hazardous, toxic or dangerous
waste, substance or material, as now or at any time hereinafter in effect
(collectively "Environmental Laws"). Tenant hereby agrees to indemnify Landlord
and hold Landlord harmless from and against any and all losses, liabilities,
including strict liability, damages, injuries, expenses, including reasonable
attorneys' fees, costs of settlement or judgment and claims of any and every
kind whatsoever paid, incurred or suffered by, or asserted against, Landlord by
any person, entity or governmental agency for, with respect to, or as a direct
or indirect result of, the presence in, or the disposal, escape, leakage,
spillage, discharge, emission or release from, the Project of any Hazardous
Substances (including, without limitation, any losses, liabilities, including
strict liability, damages, injuries, expenses, including reasonable attorneys'
fees, costs of any settlement or judgment or claims asserted or arising under
the Comprehensive Environmental Response, Compensation and Liability Act
["CERCLA"], any so-called federal, state or local "Superfund" or "Superlien"
laws or any other Environmental Law); provided, however, that the foregoing
indemnity is limited to matters arising solely from Tenant's violation of the
covenant contained in this Section. The obligations of Tenant under this Section
shall survive any expiration or termination of this Lease.

         Tenant shall not in any manner be liable for, required to contain,
remediate, remove or clean up, bear any costs or expenses regarding or have any
responsibility whatsoever with respect to, nor does Tenant indemnify Landlord or
any other party regarding, any hazardous or toxic substances, materials or
wastes or other environmental contaminants which either (a) were already on the
Premises prior to the Term of this Lease or (b) are bought, generated, emitted,
discharged, released, spilled or disposed of on or from the Premises at any time
whatsoever by any persons, entities or parties other than Tenant or Tenant's
employees, officers, servants, agents, contractors, subcontractors, assignees,
sublessees, licensees or invitees or persons employed by any of them.

         Tenant acknowledges that Landlord has delivered to Tenant a copy of
Landlord's Phase I Environmental Site Assessment for the Project, dated March
21, 1995 and prepared by Environmental Management Group, Inc. (the "Phase I
Report"). Tenant further acknowledges that the Phase I Report is being provided
to Tenant by Landlord as an accommodation to the Tenant and is provided without
recourse, representation or guaranty by Landlord or Environmental Management
Group, Inc., as to the accuracy or completeness of its contents or conclusions.
Tenant is not authorized to rely upon the Phase I Report or the information it
contains in any decision the Tenant may make concerning the Project. Under no
circumstances does Landlord recommend Tenant's reliance on the Phase I Report or
suggest that review of the Phase I Report constitutes appropriate inquiry into
the environmental condition of the Project.

         23.      DEFAULTS BY TENANT.

         The occurrence of any of the following shall constitute an event of
default hereunder by Tenant, in addition to those provided elsewhere in this
Lease:

         (a)      Tenant shall fail to pay any installment of rent hereby
reserved when due, including without limitation the Base Rent and any Additional
Rent, and such failure shall continue for a period of ten (10) days after
written notice of such failure to pay on the due date.

         (b)      Tenant fails to observe, perform and keep each and every of
the covenants, agreements, provisions, stipulations and conditions contained in
this Lease to be observed, performed and kept by Tenant, other than the payment
of Base Rent, Additional Rent and any other sum due and payable hereunder,
including without limitation the "Rules and Regulations" for the Project of
which the Premises is a part, and unless otherwise specified herein, Tenant
persists in such failure for thirty (30) days after written notice by Landlord
requiring that Tenant correct such failure; provided, that in the event any such
failure is not reasonably susceptible of cure within such thirty (30) day
period, Tenant shall have a reasonable time to cure such failure, provided
Tenant commences cure as soon as is reasonably possible and prosecutes such cure
diligently to completion.

         (c)      Tenant shall become insolvent, or shall make a transfer in
fraud of creditors, or shall make an assignment for the benefit of creditors.

         (d)      Any petition is held against Tenant, Tenant shall file a
petition for debt relief, under any section or chapter of the national or
federal bankruptcy code, as amended, or under any applicable federal or state
bankruptcy, insolvency or other similar act, and not dismissed or vacated within
sixty (60) days of the filing thereof, or Tenant shall be adjudged bankrupt or
insolvent in proceedings filed against Tenant thereunder.

         (e)      A receiver or trustee shall be appointed for all or
substantially any of the assets of Tenant.

         (f)      [Intentionally Omitted].

         (g)      [Intentionally Omitted].

         (h)      Tenant or any guarantor of this Lease shall make a material
misrepresentation to Landlord prior to or contemporaneously with the execution
of this Lease.

         (i)      A lien is filed against the Premises, Building or Project or
Landlord's estate therein by reason of any work, labor, services or materials
performed or furnished or alleged to have been performed or furnished by Tenant
or anyone holding the Premises by, through or under Tenant and Tenant fails to
have the same canceled of record, vacated or bonded within thirty (30) days
after filing thereof.

         24.      REMEDIES.

         Upon the occurrence of any such events described in Section 23 above,
Landlord shall have the option, but not the obligation, to do any one or more of
the following in addition to, and not in limitation of, any other remedy
permitted by law, in equity or by this Lease:


                                       27
<PAGE>   28

         (a)      Terminate this Lease, in which event Tenant shall surrender
the Premises to Landlord immediately upon expiration of thirty (30) days from
the date of the service upon Tenant of written notice to that effect, without
any further notice or demand; and further, that in case Landlord shall become
entitled to the possession of the Premises by any termination of this Lease
herein provided for, and Tenant shall refuse to surrender or deliver up the
possession of the Premises after the service of notice as aforesaid, then and in
that event Landlord may, without further notice or demand and without breach of
the peace, enter into and upon the Premises, or any part thereof, and take
possession of and repossess the same as of the Landlord's former estate, and
expel, remove and put out of possession Tenant and its effects, without
prejudice to any remedy allowed by law, available in such cases; and Tenant
shall indemnify Landlord for all loss, cost, expense and damage which Landlord
may suffer by reason of such termination, whether through inability to relet the
Premises, or through decrease in rent or otherwise;

         (b)      Terminate Tenant's right of possession (but not this Lease)
and enter upon and take possession of the Premises and expel or remove Tenant
and any other person who may be occupying the Premises or any part thereof, by
entry (including the use of force, if necessary), dispossessory suit or
otherwise, without thereby releasing Tenant from any liability hereunder,
without terminating this Lease, and without being liable for prosecution or any
claim of damages therefor and, if Landlord so elects, make such alterations,
redecorations and repairs as, in Landlord's judgment, may be necessary to relet
the Premises, and Landlord may, but shall be under no obligation to do so
(except to the extent specifically required by the laws of the State of
Georgia), relet the Premises or any portion thereof in Landlord's or Tenant's
name, but for the account of Tenant, for such term or terms (which may be for a
term extending beyond the Lease Term) and at such rental or rentals and upon
such other terms as Landlord may deem advisable, with or without advertisement,
and by private negotiations, and receive the rent therefor, Tenant hereby
agreeing to pay to Landlord the deficiency, if any, between all rent reserved
hereunder and the total rental applicable to the Lease Term hereof obtained by
Landlord re-letting, and Tenant shall be liable for Landlord's reasonable
expenses in redecorating and restoring the Demised Premises and all reasonable
costs incident to such re-letting, including broker's commissions and lease
assumptions, and in no event shall Tenant be entitled to any rentals received by
Landlord in excess of the amounts due by Tenant hereunder. Tenant shall remain
liable for the payment of all Base Rent, Additional Rent and other sums due and
payable hereunder accruing after any writ of possession as to the Premises is
issued to Landlord;

         (c)      Correct or cure such default and recover such amount expended,
together with interest thereon until paid at the Default Rate, and without
limiting the generality of the foregoing, Landlord shall have the right to enter
upon the Premises by force, if necessary, without being liable for prosecution
or any claim of damages therefor, and do whatever Tenant is obligated to do
under the terms of this Lease; and Tenant agrees to reimburse Landlord on demand
for any expenses including, without limitation, reasonable attorneys' fees which
Landlord may incur in thus effecting compliance with Tenant's obligations under
this Lease and Tenant further agrees that Landlord shall not be liable for any
damages resulting to Tenant from such action, unless caused by gross negligence
or intentional misconduct of Landlord;

         (d)      Recover any and all reasonable costs incurred by Landlord
resulting directly, indirectly, approximately or remotely from such default,
including but not limited to reasonable attorneys' fees.

         In the event of a default or threatened default of this Lease by
Tenant, Landlord shall be entitled to all equitable remedies, including without
limitation, injunction and specific performance.

         In the event Tenant fails to pay any installment of rent hereunder as
and when such installment is due, Tenant shall pay to Landlord on demand a late
charge in the amount equal to five percent (5%) of


                                       28
<PAGE>   29

such installment; and the failure to pay such late charge within ten (10) days
after written demand therefor shall be an event of default hereunder. The
provision for such late charge shall be in addition to all of Landlord's other
rights and remedies hereunder or at law and shall not be construed as liquidated
damages or as limiting Landlord's remedies in any manner.

         Pursuit of any of the foregoing remedies shall not preclude pursuit of
any of the other remedies herein provided or any other remedies provided by law,
nor shall pursuit of any remedy herein provided constitute a forfeiture or
waiver of any rent due to Landlord hereunder or of any damages accruing to
Landlord by reason of the violation of any of the terms, provisions and
covenants herein contained. No waiver by Landlord of any violation or breach of
any of the terms, provisions and covenants herein contained shall be deemed or
construed to constitute a waiver of any other violation or breach of any of the
terms, provision and covenants herein contained. Landlord's acceptance of the
payment of rental or other payments hereunder after the occurrence of an event
of default shall not be construed as a waiver of such default, unless Landlord
so notifies Tenant in writing. Forbearance by Landlord to enforce one or more of
the remedies herein provided upon an event of default shall not be deemed or
construed to constitute a waiver of such default. If on account of any breach or
default by Tenant in Tenant's obligation under the terms and conditions of this
lease, it shall become necessary or appropriate for Landlord to employ or
consult with an attorney concerning or to enforce or defend any of Landlord's
rights or remedies hereunder, Tenant agrees to pay any reasonable attorney's
fees. No act or thing done by the Landlord or its agents during the term hereby
granted shall be deemed an acceptance of the surrender of the Premises, and no
agreement to accept a surrender of the Premises shall be valid unless in writing
signed by Landlord. The receipt by Landlord of rent with knowledge of the breach
of any covenant or other provision contained in this lease shall not be deemed
or construed to constitute a waiver of any other violation or breach of any of
the terms, provisions and covenants contained herein.

         No termination of this Lease prior to the normal ending thereof by
lapse of time or otherwise shall affect Landlord's rights to collect sums due
hereunder for the period prior to termination thereof.

         In the event Landlord owes any sums to Tenant pursuant to the terms of
this Lease, and the same are not timely paid or credit to Tenant as provided
herein, Landlord agrees that such sums shall accrue interest until paid or
credited at the Default Rate.

         25.      FORCE MAJEURE.

         In the event that either party hereto shall be delayed or hindered in
or prevented from the performance of any act required hereunder or the
completion or performance of any work required hereunder by reason of strikes,
lock-outs, labor troubles, civil commotion, inability to procure materials,
failure of power, restrictive government laws or regulation, riots,
insurrection, war, acts of God or other reason beyond the reasonable control of
such party (other than inability to obtain funds), then performance or
completion of such act or work shall be extended for a period equivalent to the
period of such delay (hereinafter sometimes referred to as "Force Majeure
Delay"). The provisions of this Section shall not cancel or postpone or delay
the due date of any payment to be made by Tenant hereunder, or operate to excuse
Tenant from prompt payment of Base Rent, Additional Rent or any other amount due
required by the terms of this Lease.


                                       29
<PAGE>   30

         26.      ATTORNEYS' FEES.

         In the event either party institutes legal proceedings against the
other for breach of or interpretation of any of the terms, conditions or
covenants of this Lease, the party against whom a judgment is entered shall pay
all reasonable costs and expenses relative thereto, including reasonable
attorneys' fees of the prevailing party. Further, in the event Landlord engages
the services of an attorney to collect any rent due or recovery of the
possession of the Premises from Tenant, Tenant agrees to pay Landlord reasonable
attorney's fees and expenses for the services of the attorney, whether suit is
actually filed or not and other reasonable costs of collection.

         27.      ESTOPPEL CERTIFICATE.

         Tenant shall, at any time and from time to time, upon not less than
fifteen (15) days' prior written notice from Landlord, execute, acknowledge and
deliver to Landlord a statement in writing certifying that this Lease is
unmodified and in full force and effect (or if modified, stating the nature of
such modification and certifying that this Lease, as so modified, is in full
force and effect) and the dates to which the rent and other charges are paid,
and acknowledging that Tenant is paying rent on a current basis with no offsets
or claims, and that there are not, to Tenant's knowledge, any uncured defaults
on the part of Landlord hereunder (or specifying such offsets, claims or
defaults, if any are claimed) and such other information reasonably required by
Landlord. It is expressly understood and acknowledged that any such statement
may be relied upon by any prospective purchaser or encumbrancer of all or any
portion of the Project or by any other person to whom it is delivered.

         Landlord shall, at any time and from time to time, but not more often
than three (3) times in any calendar year during the Term, upon not less than
fifteen (15) days' prior written notice from Tenant, execute, acknowledge and
deliver to Tenant a statement in writing certifying that this Lease is
unmodified and in full force and effect (or if modified, stating the nature of
such modification and certifying that this Lease, as so modified, is in full
force and effect) and the dates to which the rent and other charges are paid,
and that there are not, to Landlord's knowledge, any uncured defaults on the
part of Tenant hereunder (or specifying such default, if any) and such other
information reasonably required by Tenant. It is expressly understood and
acknowledged that any such statement may be relied upon by any prospective
assignee or sublessee of all or any portion of the Premises or by any other
person to whom it is delivered.

         28.      SUBORDINATION.

         This Lease and Tenant's interest hereunder shall at all times be
subject and subordinate to the lien and security title of any deeds to secure
debt, deeds of trust, mortgages or other interests heretofore or hereafter
granted by Landlord or which otherwise encumber or affect the Premises and to
any and all advances to be made thereunder and to all renewals, modifications,
consolidations, replacements, substitutions and extensions thereof (all of which
are hereinafter called the "Mortgage"). This clause shall be self-operative and
no further instrument of subordination need be required by any holder of any
Mortgage. In confirmation of such subordination, however, Tenant shall, at
Landlord's reasonable request, promptly execute, acknowledge and deliver any
instrument which may be reasonably required to evidence subordination to any
Mortgage and to the holder thereof, and, in the event of a failure so to do,
Tenant shall be in default of this Lease.


                                       30
<PAGE>   31

         Landlord shall obtain and deliver to Tenant from the holder of any
Mortgage superior to this Lease (a "Superior Interest") a commercially
reasonable, written subordination, non-disturbance and attornment agreement
("SNDA") in recordable form providing in essence that so long as Tenant performs
all of the terms, covenants and conditions of this Lease and agrees to attorn to
the mortgagee, beneficiary of the deed of trust, purchaser at a foreclosure
sale, prime lessor or fee owner, Tenant's rights under this Lease shall not be
disturbed and shall remain in full force and effect for the Term, and Tenant
shall not be joined by the holder of any Mortgage unless required by law. Tenant
acknowledges and agrees that Tenant shall, without limitation, execute and
deliver the form of SNDA attached hereto as Exhibit "E", or such other
commercially reasonable form of SNDA which may be required by any present or
future mortgagee, trustee, fee owner, prime lessor or any person having a
Superior Interest to this Lease. Landlord represents and warrants that, as of
the date hereof, the only Superior Interest to this Lease is that certain deed
to secure debt made and entered into by Landlord in favor of Century Life
Insurance Company. Tenant acknowledges and confirms that the form of SNDA
attached hereto as Exhibit "E" is acceptable to Tenant and Tenant agrees to
execute and deliver such SNDA to Landlord and any mortgagee upon request.

         Subject to the terms of the SNDA among Landlord, Tenant and the holder
of any Mortgage, if the holder of any Mortgage shall hereafter succeed to the
right of Landlord under this Lease, whether through possession or foreclosure
action or otherwise, Tenant shall attorn to and recognize such successor as
Tenant's Landlord under this Lease and shall promptly execute and deliver any
instrument that may be necessary to evidence such attornment. Upon such
attornment, this Lease shall continue in full force and effect as a direct Lease
between such successor Landlord and Tenant, subject to all of the terms,
covenants and conditions of this Lease. In the event of a sale or conveyance by
Landlord of Landlord's interest in the Premises other than a transfer for
security purposes only, Landlord shall be relieved, from and after the date of
transfer, of all obligations and liabilities accruing thereafter on the part of
Landlord, provided that (i) any funds in the hands of Landlord at the time of
transfer in which Tenant has an interest shall be delivered to the successor of
Landlord and (ii) subject to the terms of the SNDA among Landlord, Tenant and
the holder of any Mortgage, the purchaser or assignee has assumed in writing all
obligations of Landlord under this Lease arising after the date of the transfer.
This Lease shall not be affected by any such sale and Tenant shall attorn to the
purchaser or assignee.

         29.      DEFINITIONS.

         These definitions apply to the terms defined as those terms are used
throughout this Lease:

         (a)      "Abandon" means the vacating of all or a substantial portion
of the Premises by Tenant, whether or not Tenant is in default of the rental
payments due under this Lease.

         (b)      An "act of God" or "force majeure" or "Force Majeure" is
defined for purposes of this Lease as strikes, lockouts, sit-downs, material or
labor restrictions by a governmental authority, riots, floods, washouts,
explosions, earthquakes, fire, storms, acts of the public enemy, wars,
insurrections and any other cause not reasonably within the control of Landlord
and which by the exercise of due diligence Landlord is unable, wholly or in
part, to prevent or overcome.

         (c)      The "Commencement Date" shall be the date set forth in Section
2. The Commencement Date shall constitute the commencement of this Lease for all
purposes. The Commencement Date is subject to delay as provided in Section 3 of
Exhibit "B."


                                       31
<PAGE>   32

         (d)      The "Completion Date" is defined in provided in Section 3 of
Exhibit "B." In the event that the improvements have not in fact been
substantially completed for occupancy as of January 1, 2001, Landlord shall not
be liable to Tenant for any loss or damage, except for any applicable liquidated
damages as expressly and specifically provided in Section 2 above.

         30.      SUCCESSORS.

         This Lease shall be binding and inure to the benefit of Landlord and
Tenant and their respective heirs, personal representatives, successors and
assigns, subject always in the case of Tenant to the provisions of Section 20
above. It is hereby covenanted and agreed that should Landlord's interest in the
Premises cease to exist for any reason during the Term of this Lease, then
notwithstanding the happening of such event this Lease nevertheless shall remain
unimpaired and in full force and effect and Tenant hereunder agrees to attorn to
the then owner of the Premises.

         31.      ENTIRE AGREEMENT.

         Tenant acknowledges that there are no covenants, representations,
warranties or conditions, express or implied, collateral or otherwise, forming
part of or in any way affecting or relating to this Lease save as expressly set
out in this Lease. This Lease, including all attachments, exhibits and schedules
attached hereto (all of which are incorporated herein by reference), contains
the entire agreement between the parties. No failure of Landlord to exercise any
power given Landlord hereunder or to insist upon strict compliance by Tenant of
any obligation 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
strict compliance with the terms hereof.

         32.      NOTICE.

         (a)      All rent and other payments required to be made by Tenant

         33.      REAL ESTATE COMMISSION and AGENCY DISCLOSURE.

         Important notice concerning agency relationships and payment of
commissions and fees:

         (a)      Lavista Associates, Inc. ("Lavista") has acted as agent for
the Landlord in this transaction and is to be paid a commission by Landlord upon
and subject to the terms and conditions of a written agreement between Landlord
and Lavista. Lavista has not acted as agent in this transaction for the Tenant.

         (b)      Icon Commercial Interests, L.L.C. ("Icon") has acted as agent
for the Tenant in this transaction and is to be paid a commission by Landlord
upon and subject to the terms and conditions of a written agreement between
Landlord and Icon. Icon has not acted as agent for Landlord in this transaction
for the Landlord. Icon and Lavista are herein sometimes collectively referred to
as "Brokers."

         (c)      Landlord and Tenant each represent to the other that they have
dealt with no broker, agent or finder in connection with this Lease other than
Brokers. Landlord and Tenant each hereby indemnify the other and agree to hold
the other harmless from and against any and all claims, causes, demands, losses,
liabilities, fees, commissions, settlements, judgments, damages, expenses and
fees (including attorney's fees and court costs) in connection with any claim
for commission, fees, compensation or other charge relating in any way to this
Lease, or to the consummations of the transactions contemplated hereunder, which
may be made by any person, firm or entity (other than Brokers) based upon any
agreement or agreements made or alleged to have been made by such party or its
representatives. The provisions of this Section shall survive termination or
expiration of this Lease.

         34.      SURVIVAL.

         Any claim, cause of action, liability or obligation arising under the
Term of this Lease and under the provisions hereof in favor of a party hereto
against or obligating the other party hereto shall survive the expiration or any
earlier termination of this Lease. Provided, however, Landlord shall have no
right to commence an action against Tenant after the second anniversary of the
end of the term of this Lease for Tenant's failure to pay Base Rent, CAM
Charges, Tax Charges or Insurance Charges.

         35.      SEVERABILITY.

         The terms, conditions, covenants and provisions of this Lease shall be
deemed to be severable. If any clause or provision herein contained shall be
adjudged to be invalid or unenforceable by a court of competent jurisdiction or
by operation of any applicable law, it shall not affect the validity of any
other clause or provision herein, but such other clauses or provisions shall
remain in full force and effect.

         36.      EXTERIOR COMMON AREAS.

         Tenant acknowledges and agrees that the Common Areas of the Building
including, without limiting the generality of the foregoing, lawns, gardens,
parking areas, sidewalks, and driveways, shall at all times be subject to
Landlord's right to change the area, level, location and arrangement of the
Common Areas so long as in so doing Landlord does not materially and adversely
affect ingress to and egress from the Building. Landlord shall have the right
from time to time to close all or any portion of the same to such extent as may
in the opinion of Landlord's counsel be legally sufficient to prevent a
dedication thereof or the accrual or creation of any rights to any person or the
public therein, and to obstruct or close off any or all of the exterior Common
Areas for the purposes of maintenance or repair and to do and perform such other
acts and things in and to the Common Areas as, in the use of good business
judgement, Landlord deems desirable. Tenant, for itself, its servants, agents,
employees, contractors, subcontractors, licensees and invitees, covenants,
acknowledges and agrees that its indemnification of Landlord set forth herein
shall extend to and include any occurrence upon or within the exterior Common
Areas, including the parking lot, and the insurance required to be obtained and
maintained in force by Tenant shall extend to and include occurrences involving
Tenant, its servants, agents, employees, contractors, subcontractors, licensees
and invitees upon or within the exterior Common Areas of the Building, including
the parking lots, to the fullest extent of Landlord's insurable interest
therein.

         37.      RECORDING.

         Neither this Lease, nor any portion hereof, shall be recorded.

         38.      TIME IS ESSENCE.

         Time is of the essence of this Lease.


         39.      NO ESTATE IN LAND.

         This Lease shall create the relationship of landlord and tenant between
Landlord and Tenant, and nothing contained herein shall be deemed or constructed
by the parties hereto, or by any third party, as creating the relationship of
principal and agent, or of partnership, or of joint venture, or of any
relationship other than landlord and tenant, between the parties hereto; no
estate shall pass out of Landlord; Tenant has only a usufruct not subject to
levy and sale.

         40.      LIMITATION OF LIABILITY.

         Excepting for the gross negligence or willful misconduct of Landlord,
its agents and employees, and to the extent not covered by Tenant's insurance,
Landlord shall not be liable to Tenant in any manner whatsoever for failure or
delay in furnishing any service required of Landlord, if any, provided for in
this Lease, and no such failure or delay to furnish any service or services by
Landlord shall be an actual or constructive eviction of Tenant nor shall any
such event operate to relieve Tenant from the prompt and punctual performance of
each and all the covenants to be performed herein by Tenant; nor shall Landlord
be liable to Tenant for damage to person or property caused by defects in the
cooling, heating, electric, water, elevator or other apparatus or systems or by
water discharged from sprinkler systems, if any, in the Building; nor shall
Landlord be liable to Tenant for the theft, or loss of any property of Tenant
whether from the Premises or any part of the Building or property adjoining the
Building containing the Premises. Landlord agrees to make reasonable efforts to
protect Tenant from interference or disturbance of third persons including other
tenants, however, Landlord shall not be liable


                                       34
<PAGE>   35

for any such interference or disturbance whether caused by another tenant or
tenants or Landlord or other person, nor shall Tenant be relieved from any
obligation herein because of such interference, disturbance or breach.
Notwithstanding anything contained in this Lease to the contrary, Landlord's
liability under this Lease shall be limited solely to fifty-four percent (54%)
of Landlord's equity interest in the Project, as such equity interest is
constituted from time to time, including the proceeds of the sale or other
transfer thereof, and Landlord shall not have any personal liability with
respect to this Lease.

         41.      MISCELLANEOUS.

         Words of any gender used in this Lease shall be held and construed to
include any other gender, and words in the singular number shall be held to
include the plural unless the context otherwise requires. The captions are
inserted in this Lease for convenience only, and in no way define, limit or
describe the scope or intent of this Lease, or of any provision hereof, nor in
any way affect the interpretation of this Lease. This Lease is made and
delivered in the State of Georgia and shall be governed by and construed in
accordance with the laws of the State of Georgia. The submission or delivery of
this document for examination and review does not constitute an option, an offer
to lease space in the Building or an agreement to lease. This document shall
have no binding effect on the parties unless and until executed by both Landlord
and Tenant. This Lease may be executed in any number of counterparts, each of
which shall be deemed an original and any of which shall be deemed to be
complete in itself and may be introduced into evidence or used for any purpose
without the production of the other counterparts.

         42.      HOLDING OVER.

         If Tenant remains in possession of all or any portion of the Premises
after the expiration or earlier termination of the Term of this Lease, without
Landlord's acquiescence and without any distinct written agreement of the
parties, Tenant shall be a Tenant at sufferance, and there shall be no renewal
of this Lease by operation of law. During the initial 30 days of such holdover
period, Tenant shall pay holdover rent equal to 125% of the amount of the last
Base Rent and Additional Rent due from Tenant prior to such holdover. During the
balance of any such holdover period, Tenant shall pay holdover rent equal to
150% of the amount of the last Base Rent and Additional Rent due from Tenant
prior to such holdover. The inclusion of the two immediately preceding sentences
shall not be construed as Landlord's consent for Tenant to hold over.

         43.      SURRENDER OF LEASED PREMISES.

         Subject to the provisions of Section 12 above, at the termination of
this Lease, Tenant shall surrender the Premises and keys thereto to Landlord in
same condition as at commencement of the Lease Term, normal wear and tear only
excepted.

         44.      RULES AND REGULATIONS.

         The rules and regulations with regard to the Project, 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 Project
on a non-discriminatory basis, are hereby made a part of this Lease as Exhibit
"D" and shall, during the Term of this Lease, be in all things observed and
performed by Tenant and by Tenant's employees, servants and agents.


                                       35
<PAGE>   36

         45.      [INTENTIONALLY OMITTED].

         46.      AUTHORITY.

         If Tenant is a corporation, each individual executing this Lease on
behalf of said corporation represents and warrants that he is duly authorized to
execute and deliver this Lease on behalf of said corporation, in accordance with
the bylaws and resolutions of said corporation, and that this Lease is binding
upon said corporation.

         47.      SPECIAL STIPULATIONS.

         The special stipulations attached hereto as Exhibit "C" are hereby
incorporated herein by this reference as though fully set forth. To the extent
the special stipulations conflict with or are inconsistent with the foregoing
provisions of this Lease or any exhibit to this Lease, the special stipulations
shall control.

         IN WITNESS WHEREOF, the parties herein have hereunto set their hands
and seals as of the 6th day of October, 2000.

                                    EXHIBIT B
                          TENANT IMPROVEMENT AGREEMENT

1.       INITIAL IMPROVEMENTS. Notwithstanding anything to the contrary
contained or implied in this Lease, except as otherwise expressly and
specifically provided in this Lease, (i) Tenant agrees that it is leasing the
Premises in an "as is, where is" condition, and that no representations,
warranties, or inducements, with respect to any condition of the Premises have
been made by Landlord, or its designated representatives, to Tenant, or its
designated representatives, and (ii) Tenant hereby acknowledges that no promises
to decorate, alter, repair or improve the Premises, either before or after the
execution of this Lease have been made to Tenant, or its designated
representatives, by Landlord, or its designated representatives. Landlord shall
cause to be performed the improvements (the "Initial Improvements") in the
Premises in accordance with the Plans (as such term is hereinafter defined). As
used herein, the term "Plans" means and refers to those certain plans and
specifications prepared by Crowley & Luckett Architects, Inc., dated September
19, 2000 (Project number 20168, sheets A-1 through A-6), approved by Tenant
(initialed by Tenant on September 20, 2000) and Landlord. The Initial
Improvements shall be performed at the Landlord's cost, except as otherwise
provided below.

         Landlord's approval of any of the Plans (or any modifications or
changes thereto) shall not impose upon Landlord or its agents or representatives
any obligation with respect to the design of the Initial Improvements or the
compliance of such Initial Improvements or the Plans with applicable
governmental requirements.

         Landlord shall select a contractor (the "Contractor") to perform the
construction of the Initial Improvements. Landlord shall use commercially
reasonable efforts (which may include, but need not necessarily require, the use
of overtime labor), to cause the Initial Improvements to be substantially
completed, except for minor "Punch List" items, on or before January 1, 2001,
subject to Tenant Delay (as defined below) and Force Majeure.

         Landlord, or an agent of Landlord, shall provide project management
services in connection with the construction of the Initial Improvements and the
Change Orders (hereinafter defined), if any. Such project management services
shall be performed, at Tenant's cost, for a fee of five percent (5%) of all
costs related to the construction of any Change Orders.

2.       CHANGE ORDERS. If, prior to the Commencement Date, Tenant shall require
improvements or changes (individually or collectively, "Change Orders") to the
Premises in addition to, revision of or substitution for the Initial
Improvements, Tenant shall deliver to Landlord for its reasonable approval plans
and specifications for such Change Orders. If Landlord does not approve of the
plans for Change Orders, Landlord shall advise Tenant of the revisions required.
Tenant shall revise and redeliver the plans and specifications to Landlord
within five (5) business days of Landlord's advice or Tenant shall be deemed to
have abandoned its request for such Change Orders. Tenant shall pay to Landlord
upon demand as Additional Rent for all preparations and revisions of plans and
specifications relating to Change Orders and for the construction of all Change
Orders. Landlord has no obligation to pay for costs of any Change Orders. Tenant
shall pay such costs to Landlord as Additional Rent prior to commencement of
construction of Change Orders.


                                       39
<PAGE>   40

3.       COMMENCEMENT DATE DELAY. The Commencement Date shall be delayed until
the Initial Improvements have been substantially completed (the "Completion
Date"), except to the extent that the delay shall be caused by any one or more
of the following (a "Tenant Delay"):

(a)      Tenant's request for Change Orders whether or not any such Change
Orders are actually performed; or

(b)      Contractor's performance of any Change Orders; or

(c)      Tenant's request for materials, finishes or installations requiring
unusually long lead times (it being agreed by Landlord that, provided that
Tenant makes selections of materials and finishes from Landlord's existing list
of Building standard items that are currently available, the initially approved
Plans do not require materials, finishes or installations requiring unusually
long lead times); or

(d)      [Intentionally Omitted]; or

(e)      Tenant's delay in providing information necessary to the normal
progression of the project. Tenant shall provide such information not later than
three business days after receipt of such request for information from the
Landlord; or

(f)      Tenant's delay beyond applicable notice and cure periods in making
payments to Landlord for costs of Change Orders; or

(g)      Any other act or omission by Tenant, its agents, contractors or persons
employed by any of such persons; or

(h)      Tenant's failure to duly execute and unconditionally execute this Lease
to Landlord on or before October 6, 2000.

If the Commencement Date is delayed for any of the aforementioned reasons, then
Landlord shall cause Landlord's architect to certify the date on which the
Initial Improvements would have been completed but for such Tenant Delay, or
were in fact completed without any Tenant Delay. Landlord or Landlord's agent,
Dean Weaver of LaVista Associates, shall notify Tenant of any Tenant Delay
within five (5) days of the occurrence of the event causing such delay, unless
Tenant is already aware or should have been aware of the existence of such
Tenant Delay, it being the intention that such requirement to give notice shall
be applicable only in circumstances that Tenant would not reasonably be expected
to know that an event has caused or will cause a Tenant Delay. If Landlord or
Landlord's agent fails to timely give such notice of a Tenant Delay in
circumstances that Tenant would not reasonably be expected to know that an event
has caused or will cause a Tenant Delay, such failure shall result in the delay
not being a Tenant Delay. Landlord and Tenant expressly agree that,
notwithstanding anything to the contrary in Section 32 of the Lease, (i) for
purposes of providing notices to Tenant of a Tenant Delay, Landlord shall be
permitted to send such notices to Tenant via facsimile to Tenant at facsimile
number 404.297.8588, Attn: Mr. Samuel Schwartz, and via any other method
specifically permitted for the delivery of notices under this Lease, at the
following address: Serologicals Corporation, 780 Park North Boulevard, Suite
110, Atlanta, Georgia 30021, Attn: Mr. Samuel Schwartz, and (ii) any such notice
sent by facsimile only shall be deemed sufficient notice.

4.       ACCESS BY TENANT PRIOR TO COMMENCEMENT OF TERM. Landlord at its
discretion may permit Tenant and its agents to enter the Premises prior to the
Commencement Date to prepare


                                       40
<PAGE>   41

the Premises for Tenant's use and occupancy. Any such permission shall
constitute a license only, conditioned upon Tenant's:

(a)      working in harmony with Landlord and Landlord's agents, contractors,
workmen, mechanics and suppliers and with other tenants and occupants of the
Project;

(b)      obtaining in advance Landlord's approval of the contractors proposed to
be used by Tenant and delivering to Landlord the contractor's affidavit of
payment for the proposed work and the waivers of lien from the contractor and
all subcontractors and suppliers of material; and

(c)      furnishing Landlord with such insurance as Landlord may require against
liabilities which may arise out of such entry.

Landlord shall have the right to withdraw or limit such license for cause upon
two (2) business days' written notice to Tenant (or immediately in the case of a
hazardous condition or emergency situation). Landlord shall not be liable in any
way for any injury, loss or damage which may occur to any of Tenant's property
or installations in the Premises prior to the Commencement Date, unless arising
as a result of Landlord's gross negligence or intentional misconduct. Tenant
shall protect, defend, indemnify and save harmless Landlord from all
liabilities, costs, damages, fees and expenses arising out of the activities of
Tenant or its agents, contractors, suppliers or workmen in the Premises or the
Project. Any entry and occupation permitted under this Section shall be governed
by all other terms of this Lease.

5.       MISCELLANEOUS.

Terms used in this Exhibit B shall have the meanings assigned to them in the
Lease. The terms of this Exhibit B are subject to the terms of the Lease. If
either party hereto reasonably believes that there is a good faith dispute
concerning the obligations of the other party under this Exhibit "B", such party
may (but shall be under no obligation to) give the other party written notice of
any such dispute within three (3) days after the party giving notice becomes
aware of the existence of such dispute. If the parties are unable, after good
faith negotiations, to resolve such dispute within three (3) working days after
the second party's receipt of such notice, the matter shall be submitted to and
conclusively resolved by an architect selected by mutual agreement of Landlord
and Tenant within two (2) working days after the end of such second three
working day period. If Landlord and Tenant cannot mutually agree upon such
architect within such two day period, then the Landlord's architect for the
Initial Improvements shall select the architect.

                                   EXHIBIT "C"
                              SPECIAL STIPULATIONS

1.       RENEWAL OPTION.

         (a)      Provided this Lease is in full force and effect and Tenant
shall not have been in default of any of its agreements, obligations, duties, or
covenants under this Lease beyond applicable notice and cure periods more than
twice during the Term of this Lease, and further provided that Tenant shall not
then be in default of any of its agreements, obligations, duties, or covenants
under this Lease beyond applicable notice and cure periods at the time of its
exercise of the below described Renewal Option, Tenant is hereby granted the
option to renew (the "Renewal Option") the Term of this Lease for one period of
five (5) additional years (the "Renewal Term"). Tenant shall exercise the
Renewal Option by delivering irrevocable written notice of such election to
Landlord at least six (6) months, but not more than nine (9) months, prior to
the expiration of the initial Term of this Lease. The renewal of this Lease
shall be upon the same terms and conditions of this Lease, except (i) the Base
Rent during the Renewal Term shall be calculated based on the prevailing Market
Base Rental Rate (as such term is defined below) at the time the Renewal Term
commences (provided in no event shall the Base Rent be less than 95% of the then
prevailing Base Rent reserved in this Lease at the expiration of the initial
Lease Term), (ii) Tenant shall have no option to renew this Lease beyond the
expiration of the Renewal Term, (iii) Tenant shall not have the right to assign
its renewal rights to any sublessee of all or any portion of the Premises or
assignee of this Lease (except with respect to an Affiliate assignee or, in the
event and only in the event that there has been a permitted assignment of this
Lease during the last two years of the initial Lease Term, a non-Affiliate
assignee), nor may any such sublessee or assignee (other than an Affiliate
assignee or, in the event and only in the event that there has been a permitted
assignment of this Lease during the last two years of the initial Lease Term, a
non-Affiliate assignee) exercise or enjoy the benefit of such renewal rights,
(iv) the leasehold improvements will be provided in their then-existing
condition (on an "as is" basis in the broadest sense of the term) at the time
the Renewal Term commences, and (v) there shall not be any rent abatement period
and Tenant shall not be entitled to cash payment or allowance of any nature or
amount whatsoever. If Tenant shall fail to exercise the Renewal Option within
the time permitted, or the conditions set forth above are not entirely
satisfied, the Renewal Option shall automatically terminate, this Lease shall
expire at the expiration of the initial Lease Term and Tenant shall have no
further right thereafter to renew this Lease or to acquire any interest
whatsoever in the Premises. If Tenant shall remain in possession of the Premises
after the expiration of the original Term without there having been executed
between Landlord and Tenant an amendment to this Lease as contemplated by the
terms of this Section, then Tenant shall be a Tenant holding over as provided in
this Lease. Whenever used in this Lease, the term "Market Base Rental Rate"
shall mean the then prevailing annual rental rate per square foot (exclusive of
expense pass-through additions) of rentable area then being charged in
comparable office buildings located in the Peachtree Corners submarket of
Atlanta, Georgia, for space comparable to the space for which the Market Base
Rental Rate is being determined (taking into consideration use, location and/or
floor level within the applicable building, the definition of rentable area,
leasehold improvements provided, remodeling credits or allowances granted,
quality, age and location of the applicable building, rental concessions (such
as abatements or lease assumptions), the provision of free or paid unassigned
parking, the time the particular rate under consideration became effective, size
of tenant, relative operating expenses, relative services provided, etc.). It is
agreed that bona fide written offers to lease comparable space located elsewhere
in the Project from unaffiliated third parties (at arms length) may be used by
Landlord as an indication of Market Base Rental Rate.


                                       42
<PAGE>   43

         (b)      Market Base Rental Rate shall be determined as follows:

         (i) If Tenant provides Landlord with its binding notice of exercise
pursuant to Subsection (a) above, then within thirty (30) days after the date of
Landlord's receipt of Tenant's election to exercise the Renewal Option, Landlord
shall calculate and inform Tenant of the Market Base Rental Rate. If Tenant
rejects the Market Base Rental Rate as calculated by Landlord, Tenant shall
inform Landlord of its rejection within ten (10) days after Tenant's receipt of
Landlord's calculation, and Landlord and Tenant shall commence negotiations to
agree upon the Market Base Rental Rate. If Tenant fails to timely reject
Landlord's calculation of the Market Base Rental Rate it will be deemed to have
accepted such calculation. If Landlord and Tenant are unable to reach agreement
within twenty-one (21) days after Landlord's receipt of Tenant's notice of
rejection, then the Market Base Rental Rate shall be determined in accordance
with (ii) below.

         (ii) If Landlord and Tenant are unable to reach agreement on the Market
Base Rental Rate within said twenty-one (21) day period, then within seven (7)
days, Landlord and Tenant shall each simultaneously submit to the other in a
sealed envelope its good faith estimate of the Market Base Rental Rate. If the
higher of such estimates is not more than one hundred five percent (105%) of the
lower, then the Market Base Rental Rate shall be the average of the two.
Otherwise, the dispute shall be resolved by arbitration in accordance with (iii)
and (iv) below.

         (iii) Within seven (7) days after the exchange of estimates, the
parties shall select as an arbitrator an independent MAI appraiser with at least
five (5) years of experience in appraising office space in the metropolitan area
in which the Project is located (a "Qualified Appraiser"). If the parties cannot
agree on a Qualified Appraiser, then within a second period of seven (7) days,
each shall select a Qualified Appraiser and within ten (10) days thereafter the
two appointed Qualified Appraisers shall select a third Qualified Appraiser and
the third Qualified Appraiser shall be the sole arbitrator. If one party shall
fail to select a Qualified Appraiser within the second seven (7) day period,
then the Qualified Appraiser chosen by the other party shall be the sole
arbitrator.

         (iv) Within twenty-one (21) days after submission of the matter to the
arbitrator, the arbitrator shall determine the Market Base Rental Rate by
choosing whichever of the estimates submitted by Landlord and Tenant the
arbitrator judges to be more accurate. The arbitrator shall notify Landlord and
Tenant of its decision, which shall be final and binding. Landlord and Tenant
agree that in no event shall the Market Base Rental Rate be less than 95% of the
then prevailing Base Rent reserved in this Lease at the expiration of the
initial Lease Term. If the arbitrator believes that expert advice would
materially assist him, the arbitrator may retain one or more qualified persons
to provide expert advice. The fees of the arbitrator and the expenses of the
arbitration proceeding, including the fees of any expert witnesses retained by
the arbitrator, shall be paid by the party whose estimate is not selected. Each
party shall pay the fees of its respective counsel and the fees of any witness
called by that party.

2.       RIGHT OF FIRST OFFER TO PURCHASE PROJECT.

(a)      Except as hereinafter provided, during the Lease Term and provided that
(i) Tenant shall not have defaulted in the performance of any of its agreements,
obligations, duties, or covenants under this Lease beyond any applicable notice
and cure period more than three time, (ii) Tenant shall not then be in default
in the performance of any of its agreements, obligations, duties, or covenants
under this Lease beyond any applicable notice and cure period at the time of any
proposed transfer of the Project which is subject to the terms of this Special
Stipulation, (iii) the original named Tenant herein is leasing and occupying all
of the rentable square feet in the Building, and (iv) Tenant shall not have
assigned this Lease to any person or entity, other than an Affiliate, Landlord
shall not transfer or convey its fee title to the Project in a Single Asset
Transaction (as such term is hereinafter defined) without first complying with
the provisions of this Section. As used herein, the term "Single Asset
Transaction" shall mean a sale transaction that does not involve any land or
improvements other than the Project. Should Landlord desire to so transfer or
convey the Project in a Single Asset Transaction, Landlord shall give Tenant
notice thereof, which notice shall specify the cash consideration which Landlord
would accept for the transfer and conveyance of the Project to Tenant, free of
mortgage debt. Tenant shall have thirty (30) calendar days after such notice
(the "Due Diligence Period") in which to elect either to purchase the Project
for such cash consideration or to elect not to so purchase. During the Due
Diligence Period, subject to the rights of other tenants of the Project, Tenant
shall, if and to the extent it desires to do so, independently obtain, perform
and approve at its sole expense:

         (i)      engineering reports, including, without limitation, an
         inspection of the structure and integrity of the buildings in the
         portions of the Project in question, including foundation, walls, roof,
         floors and supports; inspection of all mechanical systems, including
         heat, HVAC and electrical; and inspection of water and sewer systems;

         (ii)     all architectural reports and surveys as Tenant deems
         necessary;

         (iii)    all environmental inspections and reports as Tenant and its
         inspectors deem necessary of the portions of the Project in question;
         and

         (iv)     title examinations, reports and commitments for title
         insurance.

Upon request, Landlord shall furnish to Tenant, at Tenant's expense, copies of
the foregoing due diligence items which are in Landlord's possession. All of the
above inspections and reports shall be performed at reasonable times during
normal business hours upon no less than forty-eight (48) hours prior notice to
Landlord and shall not interfere with Landlord's business operations at the
Project. Tenant may not perform any soil boring tests without the prior written
consent of Landlord. Tenant shall, at Tenant's sole expense, repair any damage
caused by such soil boring tests to the reasonable satisfaction of Landlord.
Tenant further agrees to repair any damage to the Project, or any portion
thereof, and to defend, indemnify and hold Landlord harmless for any damage,
loss, cost, claim or fee (including attorney's fees) arising from any and all of
the above inspections and reports and any other inspections and reports
performed by or at the request of Tenant, its agents, contractors and employees
(including, but not limited to, accountants, appraisers, engineers and
architects). This indemnity shall survive the end of Tenant's inspections during
the Due Diligence Period and the closing. Failure of Tenant to respond to
Landlord within the Due Diligence Period shall be conclusively deemed to
constitute Tenant's election not to so purchase. If Tenant elects not to so
purchase or is deemed to have elected not to so purchase, Landlord will, upon
Tenant's request, furnish Tenant with a copy of the investment property offering
which Landlord may send to prospective purchasers of the Project at the time
Landlord markets the Project for sale, subject to any terms or conditions which
are applicable to other prospective purchasers (e.g., if a prospective


                                       44
<PAGE>   45

purchaser is required to executed Landlord's form Confidentiality and Disclaimer
Agreement as a condition precedent to receiving such investment property
offering, then Tenant shall be required to execute Landlord's form
Confidentiality and Disclaimer Agreement as a condition precedent to receiving
such investment property offering). The provisions of the immediately preceding
sentence are not intended and shall not be construed to grant to Tenant any
option or preferential right.

(b)      If Tenant elects to so purchase, then a closing of such purchase and
sale shall be held within thirty (30) days of the expiration of the Due
Diligence Period at a time and place in Atlanta, Georgia selected by Landlord.
At such closing, Landlord shall transfer by limited warranty deed fee simple
title to the Project, subject to the following matters: (i) matters of record
encumbering such title; (ii) zoning regulations, building codes and similar
ordinances (including any violations thereof); (iii) all matters which would be
disclosed by a current and accurate survey and inspection of said property; (iv)
rights of parties in possession of said property; (v) the lien of current years
ad valorem taxes; (vi) tenant leases; and (vii) inchoate mechanics and
materialmen' liens. All mortgages shall be paid out of the sales proceeds if not
discharged by Landlord prior to such conveyance. Tenant shall assume all of
Landlord's duties and obligations under all leases and service contracts for
such property from and after the date of closing. Rent, taxes, utilities and
service charges shall be prorated as of the date of closing. All recording
costs, taxes and fees shall be borne by Tenant, with the exception of the
Georgia transfer tax, which shall be paid by Landlord. Landlord and Tenant agree
to execute such other and further documentation as shall be necessary or
advisable to effectuate the foregoing as reasonably requested by the other
party.

(c)      If Tenant elects not to so purchase or is deemed to have elected not to
so purchase, Landlord shall be free to sell such property to any person or
entity within one (1) year of Landlord's notice to Tenant so long as the
consideration paid by the purchaser is not less than ninety percent (90%) of the
amount stated in Landlord's notice to Tenant, even if such consideration is not
all cash, as, for example, purchase money financing or a property exchange, but
in such cases, the non-cash consideration shall be converted to the reasonable
cash equivalent thereof for purposes of determining whether such 90% test has
been met. At any time, Landlord may send a new notice to Tenant, and if Tenant
elects not to so purchase, such one year period shall commence anew. While no
consent or waiver of Tenant shall be required, Tenant agrees to certify to any
such purchaser in writing whether the provisions hereof have been complied with
by Landlord.

(d)      This Section shall not apply to any sale, leasing of the entire Project
or other transfer between or among any current or future members or partners in
Landlord, the successors of current or future members or partners, or entities
which are affiliated with any such members, partners or successors. This Section
shall not apply to any leasing of less than all of the Project or to the grant
of easements, covenants or other encumbrances which do not result in the
divestment of substantially all of the interest of Landlord in the Project and
this Section shall not apply to any sale transaction that involves land and/or
improvements in addition to the Project. If the property is sold or transferred
after a right of first offer to purchase is afforded to Tenant under this
Section and Tenant either waives or declines to purchase, then this provision
shall expire and become null and void, and the purchaser or grantee shall take
free of this Section. Further, this Section shall not be applicable to any
financing transaction where a deed to secure debt, security deed, security
agreement, mortgage, sale and leaseback or other financing instrument
(hereinafter referred to as a "security instrument") is granted to encumber the
Project or any portion thereof or parts thereof or interests therein or
interests in


                                       45
<PAGE>   46

Landlord as security for debt and/or obligations, and it shall not apply to any
foreclosure sale or deed in lieu of foreclosure under any such security
instrument. It is intended that this Section is unconditionally subordinate and
inferior to any security instrument now or hereafter granted on any of the
aforementioned properties or interests, and this Section shall be extinguished
upon a foreclosure sale or deed in lieu of foreclosure under a security
instrument.

3.       MONUMENT SIGN. Tenant shall have the right to procure, install, and
maintain, all at Tenant's sole cost and expense except as otherwise expressly

<PAGE>   47

have the right to use or allow any other person or entity to use the Generator
for a fee. The rights under this Section are personal to the Tenant named herein
and are not assignable except to a permitted assignee of this Lease approved by
Landlord. The Generator installed shall be and remain the property of Landlord
at the end of the Term of this Lease. Notwithstanding the foregoing, in the
event Tenant, at Tenant's cost and expense, replaces the Generator in its
entirety during the last three (3) years of the Term of this Lease, Tenant shall
be entitled to remove the Generator at the end of the Term of this Lease,
provided that Tenant


                                       48
<PAGE>   49

shall surrender the Generator Area in substantially the same condition existing
prior to the installation of the Generator. Tenant shall be liable for, and
shall promptly reimburse Landlord for, the cost of repairing all damage done to
the Generator Area or to any other portion of the Project by the removal of the
Generator, including restoring the landscape to its previous condition. Other

requirement of a Governmental Authority. "Governmental Authority" shall mean the
United States, the state, county, city and political subdivision in which the
Building is located or which exercises jurisdiction over the Building, and any
agency, department, commission, board, bureau or instrumentality of any of them
which exercises jurisdiction over the Building. Landlord shall cause the
Generator to be acquired and installed at Tenant's expense (subject to
Landlord's Generator Contribution), all in a good and workmanlike manner and in
compliance with all applicable Governmental Requirements, including, but not
limited to, all building, electric, communications, and safety codes,
ordinances, standards, regulations and requirements of any governmental
authority. Tenant shall cause the maintenance of the Generator to be made in a
good and workmanlike manner so as to not interfere with any other tenant or
occupant of the Project. Unless the parties otherwise agree, Cummins South Inc.
will be selected as the contractor to install the Generator. Tenant shall use
best efforts to cause Cummins South Inc. to deliver, on or before October 13,
2000, plans and specifications for the Generator and the aesthetic screening of
the same to Landlord and Tenant. Such plans and specifications are subject to
Landlord's consent, such consent not to be unreasonably withheld. Landlord and
Tenant agree to act in good faith to attempt to mutually approve such plans and
specifications within seven (7) days after Cummins South Inc. delivers such
plans and specifications to Landlord and Tenant. The operation of the Generator
shall not disturb or interfere with the systems of the Project or with any other
tenant or occupant of the Project. Tenant covenants that in no event shall the
operation of the Generator damage the Project or any portion thereof or existing
structure on the Building, or interfere with the maintenance of the Project, any
system currently serving the Project, any equipment currently being operated
from or within the Project or portion thereof, or in any manner invalidate or
otherwise adversely affect any existing warranties in place on the Building or
on any improvements to the Building. Tenant shall pay for all preparations and
revisions of plans and specifications relating to the Generator, and for the
acquisition and installation of the Generator, subject to Landlord's Generator
Contribution. Provided Tenant is not in default hereunder, Landlord shall
contribute an amount up to $50,000.00 ("Landlord's Generator Contribution")
toward the costs incurred for the acquisition and installation of the Generator,
including all related equipment such as cabling, transfer switch, electrical
phasing panels, fuel source and aesthetic screening as shall be required for the
installation of the Generator. Landlord has no obligation to pay for any costs
relating the Generator in excess of Landlord's Generator Contribution. Any costs
in excess of Landlord's Generator Contribution (herein, the "Excess


                                       49
<PAGE>   50

Generator Costs") shall be paid by Tenant to Landlord upon substantial
completion of the installation of the Generator. Tenant acknowledges that the
Excess Generator Costs are estimated to be no less than $26,000 and may in fact
be in excess of such amount. To avoid any doubt, the Completion Date (as defined
in Exhibit "B") (i.e., the date of substantial completion of the Initial
Improvements) shall not be affected in any way by the date on which the
installation of the Generator is complete, and in no event shall the Generator
installation work result in any extension or delay in the Commencement Date.

         (d)      Landlord shall not be liable to Tenant for any stoppages or
shortages of power furnished to the Generator or to the Generator Area because
of any act, omission or requirement of the public utility serving the Building,
or the act or omission of any other tenant, licensee or contractor of the
Building, or for any other cause beyond the control of Landlord, and Tenant
shall not be entitled to any rental abatement for any such stoppage or shortage
of power. Tenant shall operate the Generator in strict compliance with
Landlord's rules and regulations, now or hereafter promulgated, and all
applicable Governmental Requirements. Tenant shall, at Tenant's expense, be
solely responsible throughout the Term for maintaining, servicing and repairing
the Generator and for repairing any damage to the Building or any systems or
equipment serving the Building caused by the Generator or by any act, negligence
or misconduct of Tenant, Tenant's employees, agents or contractors, while
installing, using, servicing, repairing, maintaining or removing the Generator.
Tenant shall protect, defend, indemnify and save Landlord and its officers,
directors, agents, employees, other tenants, licensees and invitees harmless
from and against any and all obligations, costs (including costs of litigation
and attorneys' fees), expenses, claims, damages and liabilities of any nature
whatsoever arising out of or in connection with the existence, installation,
construction, operation, repair, maintenance and/or removal of the Generator,
unless arising as a result of the gross negligence or intentional misconduct of
Landlord. Tenant's license under this Section shall automatically terminate upon
the earlier to occur of the end of the Term of this Lease.

         10.      SATELLITE DISH/ANTENNA.

         (a)      During the Term, Landlord shall grant to Tenant a
non-exclusive license to install, maintain, repair, replace and operate one (1)
satellite dish and/or antenna (together with any related wires, conduits and
other equipment necessary or desirable for the proper operation of such
satellite dish and/or antenna, collectively the "Satellite") in a location on
the roof of the Building designated by Landlord and reasonably acceptable to
Tenant (the "Equipment Space Area") upon and subject to all of the terms and
conditions set forth herein. The Satellite shall be used only by Tenant solely

its employees, agents and contractors shall have the right, upon prior
reasonable notice to Landlord's managing agent, to enter or leave the roof for
purposes of accessing the Satellite, subject to the terms of this Special
Stipulation 10. The Satellite installed shall be and remain the property of
Tenant, and Tenant shall, prior to the expiration or termination of this
license, remove the Satellite (including all installation and anchoring
hardware) installed in the Equipment Space Area and elsewhere in the Building,
and surrender the Equipment Space Area in substantially the same condition
existing prior to the installation of the Satellite. Tenant shall be liable for,
and shall promptly reimburse Landlord for, the cost of repairing all damage done
to the Equipment Space Area or to the Building (including the roof thereof) by
such installation or removal, including filling and sealing any holes or
cavities left by the removal of installation or anchoring hardware. Tenant
shall, at its sole cost and expense, obtain all

Lease and all applicable Legal Requirements (defined below) in effect from time

all applicable Legal Requirements, including, but not limited to, all building,
electric, communications, and safety codes, ordinances, standards, regulations
and requirements of the Federal Communications Commission and any other

specifications approved by Landlord, and the installation shall be performed by
contractors approved by Landlord, which approval shall not be unreasonably
withheld or delayed. Landlord shall not be liable to Tenant for any stoppages or
shortages of electrical power furnished to the Satellite or to the Equipment
Space Area because of any act, omission or requirement of the public utility
serving the Building, or the act or omission of any other tenant, licensee or
contractor of the Project or for any other cause beyond the reasonable control
of Landlord, and Tenant shall not be entitled to any rental abatement for any
such stoppage or shortage of electric power. Tenant shall operate the Satellite
in strict compliance with Landlord's rules and regulations, now or hereafter
promulgated, and all applicable Legal Requirements. Tenant shall, at Tenant's
expense, be solely responsible throughout the Term for maintaining, servicing
and repairing the Satellite and for repairing any damage to the Building or any
systems or equipment serving the Building caused by the Satellite or by any act,
negligence or misconduct of Tenant, Tenant's employees, agents or contractors,
while installing, using, servicing, repairing, maintaining or removing the
Satellite. Tenant shall protect, defend, indemnify and save Landlord and its
trustees, agents, employees, other tenants, licensees and invitees harmless from
and against any and all obligations, costs (including costs of litigation and
attorneys' fees), expenses, claims, damages and liabilities of any nature
whatsoever arising out of or in connection with the existence, installation,
construction, operation, repair, maintenance and/or removal of the Satellite. As

other individual or entity, including without limitation Landlord or any other
tenant of the Project, from installing communications equipment on the roof of
the Building (with related wiring, conduits and other equipment in and through
the core of the Building as necessary or desirable for the proper operation of
such communications equipment), or from using the roof for any other purpose, it
being agreed that Landlord and its designees shall have the right to do the
same; provided, however, Landlord shall not install or permit the installation
of communications equipment on the roof of the Building if the proposed

                  (i) Tenant desires to assign this Lease to an Affiliate in the
context of a merger or consolidation of Tenant or sale of all or substantially
all of the assets or stock of Tenant, and

                  (ii) the proposed Affiliate does not have a demonstrated net
worth determined in accordance with generally accepted accounting principles and
credit rating which is equal to or greater than the demonstrated net worth
determined in accordance with generally accepted accounting principles and
credit rating of Tenant on the date of execution of this Lease, and

                  (iii) the proposed Affiliate is a corporation (x) having a
net worth (calculated using generally accepted accounting principles
consistently applied and as reflected by audited financial statements prepared
by a "Big Five" accounting firm) of more than $60,000,000 (USD), and (y) having
(A) a Standard & Poor's long-term issue credit rating of "BBB" or higher on the
proposed effective date of the assignment of this Lease to the Affiliate or a
Moody's long-term issue credit rating of "BAA-3" or higher on the proposed
effective date of the assignment of this Lease to the Affiliate, or (B) if the
proposed assignee does not have a Standard & Poor's or a Moody's credit rating
on any publicly traded debt, investment grade credit worthiness equal to or
better than the creditworthiness rating as described in the immediately
preceding clause (A), as determined by Landlord in the exercise of Landlord's
reasonable business judgment after having reviewed the current financial
information on the proposed assignee made available to Landlord by the proposed
assignee and from other sources (e.g., Dun & Bradstreet) (any such Affiliate
satisfying the requirements of this clause (iii) is herein referred to as a
"Credit Worthy Affiliate"), and

                  (iv) Tenant is not in default under this Lease beyond any
applicable notice and cure period,

then, in those events and subject to the other terms and conditions contained in
Section 20 of the Lease, Landlord will consent to the assignment of the Lease to
such Affiliate.

(b)      In the event:

                  (i) Tenant desires to assign this Lease to an Affiliate in the
context of a merger or consolidation of Tenant or sale of all or substantially
all of the assets or stock of Tenant, and

                  (ii) the proposed Affiliate does not have a demonstrated net
worth determined in accordance with generally accepted accounting principles and
credit rating which is equal to or greater than the demonstrated net worth
determined in accordance with generally accepted accounting principles and
credit rating of Tenant on the date of execution of this Lease, and

                  (iii) the proposed Affiliate is not a Credit Worthy Affiliate
(as defined above), and

                  (iv) Tenant is not in default under this Lease beyond any
applicable notice and cure period, and


                                       52
<PAGE>   53

                  (v) Tenant shall have delivered or caused to be delivered to
Landlord the Letter of Credit (as defined below) prior to the assignment of the
Lease in accordance with the terms and conditions hereinbelow,

then, in those events and subject to the other terms and conditions contained in
Section 20 of the Lease, Landlord will consent to the assignment of the Lease to
such Affiliate. As a condition precedent to the requirement that Landlord grant
its consent to the assignment of this Lease to the Affiliate as provided in the
preceding sentence, Tenant shall deposit or caused to be deposited with Landlord
an irrevocable letter of credit (the "Letter of Credit"), in an amount (the
"Initial Amount") equal to the sum of the aggregate amount of Base Rent and
Additional Rent which is scheduled to become due and payable under this Lease
from and after the date of the subject assignment of this Lease through the end
of the Lease Term (including any exercised Renewal Term). For purposes of making
the calculation of such amount of Additional Rent, the CAM Charges, Insurance
Charges and Tax Charges components of such Additional Rent shall equal the
aggregate amount of CAM Charges, Insurance Charges and Tax Charges for the last
full calendar year prior to the date of such assignment, with such aggregate
amount increased by 4% per annum on a cumulative basis for the remainder of the
Lease Term (including any exercised Renewal Term). The Letter of Credit shall
(i) be issued by a commercial bank reasonably satisfactory to Landlord
("Issuer"); (ii) be an irrevocable letter of credit; (iii) be payable to
Landlord: (iv) require that any draw on the Letter of Credit shall be made only
upon receipt by the Issuer of a written certification from Landlord certifying
that the Tenant is in default under the Lease and has not cured such default;
(v) provide that it is governed by the Uniform Customs and Practice for
Documentary Credits (1993 revisions), International Chamber of Commerce
Publication No. 500; and (vi) otherwise be in a form acceptable to Landlord.
Tenant shall keep the Letter of Credit in effect during the entire Lease Term,
as the same may be extended, plus a period of four (4) weeks thereafter. At
least thirty (30) days prior to the expiration of the Letter of Credit, the term
thereof shall be renewed or extended pursuant to an amendment thereto acceptable
to the Landlord and any failure to so renew or extend the Letter of Credit shall
entitle Landlord to immediately draw down all sums available thereunder. At
least thirty (30) days prior to the commencement of any exercised Renewal Term,
the term of the Letter of Credit shall be renewed or extended in an amount equal
to the sum of the aggregate amount of Base Rent and Additional Rent which is
scheduled to become due and payable under this Lease throughout the entire
Renewal Term (and for purposes of making the calculation of such amount of
Additional Rent, the CAM Charges, Insurance Charges and Tax Charges components
of such Additional Rent shall equal the aggregate amount of CAM Charges,
Insurance Charges and Tax Charges for the last full calendar year of the initial
Lease Term, with such aggregate amount increased by 4% per annum on a cumulative
basis for the remainder of the Renewal Term) pursuant to an amendment thereto
acceptable to the Landlord and any failure to so renew or extend the Letter of
Credit shall entitle Landlord to immediately draw down all sums available under
the Letter of Credit and the Renewal Option shall, at Landlord's option, be void
notwithstanding anything contained to the contrary in Special Stipulation 1
above. Tenant may annually reduce the amount of the Letter of Credit by ten
percent (10%) of the Initial Amount on each anniversary date of the subject
assignment of this Lease to the Affiliate by an amendment or by substitution of
a new letter of credit which complies with the requirements of this paragraph,
which reflects such reduced amount (the "Amended Amount"). If a default by
Tenant has occurred beyond any applicable notice and cure period, then Landlord
shall be entitled to draw upon the Letter of Credit in the amount determined by
Landlord necessary to cure such default and compensate Landlord for any damages
suffered by Landlord as a result thereof.
