                               STOCK PURCHASE PLAN

--------------------------------------------------------------------------------

     1.   Establishment of Plan.  Applied Genetic Ventures, Inc., a Nevada
corporation (the "Company"), intends to grant to selected employees, and
advisers ("Purchaser") of the Company or any of its subsidiaries, options
("Options") to purchase shares of the Company's $.0001 par value common stock
("Common Stock"), with the flexibility to make payments on a deferred basis.
Such purchases shall be made pursuant to this Stock Purchase Plan (the "Plan").

     2.   Purpose of Plan. The purpose of the Plan is to aid in maintaining
and developing personnel to help assure the success of the Company. The Plan is
designed to help the Company retain the services of executives, advisors and key
employees and attract new personnel when needed for future operations and
growth; to offer such personnel additional incentives to put forth maximum
efforts for the success of the business; and to afford them opportunities to
obtain or increase a proprietary interest in the Company on a favorable basis
and, thereby, to have an opportunity to share in its success.

     3.   Administration of the Plan. (a) The Plan shall be administered by
the Board of Directors of the Company (the "Board") as such shall exist from
time to time. Subject to authority in its discretion (i) to interpret the Plan
and all purchases made thereunder, (ii) to prescribe, adopt, amend and rescind
rules and regulations relating to the Plan, (iii) to define the terms used in
the Plan and in the purchases granted thereunder, (iv) to determine the
individuals to whom and the time or times at which the right to purchase Common
Stock shall be granted, the number of shares subject to each purchase, the
purchase price, and all other terms and provisions thereof, which may or may not
be identical, and (v) to make all other determinations necessary or advisable
for the administration of the Plan. No member of the Board shall have the power
to vote on any matter which affects solely his own interests as a purchaser or
prospective purchaser of Common Stock hereunder. All determinations made by the
Board shall be binding on all Purchasers and on their legal representatives and
assigns.

          (b)  On grant of the right to purchase Common Stock, the Company shall
enter into a Stock Purchase Agreement with the Purchaser. The Stock Purchase
Agreement shall contain the terms and conditions of the purchase and sale.

     4.   Total Number of Shares. Subject to adjustment as provided in Section
12, the total number of shares reserved at the Effective Date (as hereinafter
defined) for purchase and sale under the Plan is 25,000,000 shares of Common
Stock. The shares so reserved may be either authorized but unissued or treasury
shares of the Company.

     5.   Eligibility. The right to purchase common stock may be granted to
any present or future employee, officer, director, or adviser (including
independent contractors) of the Company and of its subsidiary corporations. In
determining the identity of Purchasers, the number of shares

<PAGE>

available for purchase and the other terms and provisions of each purchase, the
Board may take into account the nature of the services rendered by the
respective Purchaser, their contributions to the success of the Company and such
other factors as the Board in its discretion shall deem relevant.

     6.   Purchase Price.  The purchase price of each share shall be determined
from time to time by the Board in its discretion.  In no event shall the
purchase price be less than the par value of the Stock.

     7.   Issuance of Shares and Payment Therefor. (a) As soon as possible
after receipt of an application from an eligible Purchaser, the Company will
notify him of the total amount due in connection with his purchase, and the
payment amount due in connection with his purchase, and the payment program
available to the Purchaser. The Board is not required to offer a deferred
payment program to any Purchaser, but may do so in its discretion. The stock
certificates will be registered in the name of and delivered to the Purchaser
when full and final payment is made, provided, that the Purchaser shall have the
option to have the respective number of shares registered and delivered to the
Purchaser as the payments are actually made by the Purchaser.

          (b)  In the case of a Purchaser participating in the Plan through a
deferred payment arrangement, payroll deductions may be made pursuant to the
employee's authorization beginning with the last pay period of the month
in which the employee's application is received by the Company. If a payroll
deduction is not available or not elected, the Purchaser will pay the first
installment 15 days after the date of the notice of the amount due given by the
Company and will pay succeeding payments on the same calendar day of each
succeeding month thereafter until the purchase price had been paid in full. In
no event shall deferred payment extend beyond one year from the purchase date.

          (c)  The Purchaser will have the right to prepay all or any part of
the purchase price by cash payments made to the Company at any time. No
interest will be charged to the Purchaser on the unpaid balance of the purchase
price.

     8.   Default in Payment. In the event that a Purchaser shall at any time
default in his agreements under the Plan, including withdraw his authorization
for payroll deductions, or shall fail to pay any installment within five days
after its due date, the Company, without demand and without notice to the
Purchaser, may immediately terminate the defaulting Purchaser's rights under the
Plan and commence an action for damages. Such termination shall not affect any
shares that have been fully paid by the Purchaser.

     9.   Purchaser's Rights as Shareholder.  The Purchaser will only become a
shareholder of record, and will only have the right to vote such shares at any
meeting of the shareholders as and when such shares become fully paid for by the
Purchaser.

     10.  Rights Not Transferrable. No Purchaser shall be permitted to sell,
assign, transfer, pledge, otherwise dispose of or encumber either his right to
participate in the Plan or his interest in any shares subject to purchase but
not yet fully paid for, and, such right and interest shall not be liable for or
subject to the debts of the Purchaser. If any such action is taken by the
Purchaser, or any

                                       2
<PAGE>

claim is asserted by any other party in respect of such right and interest, such
action or claim will be treated as a default by the Purchaser.

     11.  Termination of Employment or Association. Upon termination of
employment or association for any reason whatsoever, including retirement or
death, all rights of the Purchaser under the Plan shall immediately terminate,
but such termination shall not affect the Purchaser's rights to shares that have
been fully paid for prior to such termination.

     12.  Adjustments. (a) If the outstanding shares of the Common Stock of
the Company are increased, decreased, changed into or exchanged for a different
number or kind of securities of the Company, through reorganization,
recapitalization, reclassification, stock dividend, stock split, amendment to
the Company's Articles of Incorporation or other change in corporate structure,
an appropriate and proportionate adjustment shall be made in the numbers and
prices of the Purchases granted under the Plan (but not in the aggregate
purchase price), and in the total number of shares of Common Stock with respect
to which Purchases may be purchased hereunder.

          (b)  Upon the effective date of the dissolution of the Company,
or of a reorganization or merger of the Company with one or more corporations in
which the Company is not the surviving corporations, or of a transfer of all or
substantially all the assets of the Company or more than fifty percent of the
outstanding shares of Common Stock of the Company to another person (as such
term is defined in Section 13(d)(3) of the Securities Exchange Act of 1934),
unless provision has been made for continuance of the Plan, the Plan and all
deferred payment arrangements shall terminate, but, in case of such termination,
each Purchaser shall have the right to immediately pay in full any deferred
payments remaining pursuant to then existing arrangements with the Corporation.

          (c)  Adjustments under this Section shall be made by the Board,
whose determination as to what adjustments shall be made, and the extent
thereof, shall be final. No fractional shares of stock shall be issued under the
Plan.

     13.  Term of Plan. The Plan shall become effective upon its adoption by
the Board, which was accomplished at the Board of Directors meeting on December
18, 1986 and by the approval of the majority of the shareholders which was
accomplished July 22, 1988. Except as set forth above, the Plan shall continue
in effect until termination under Section 14 below or until all shares subject
to the Plan shall be issued under the Plan.

     14.  Termination and Amendment. The Board may at any time suspend or
terminate the Plan. The Board may also at any time amend or revise the terms of
the Plan, including, without limitation, the making of such amendments or
revisions as the Board shall deem advisable in order to conform to any change in
any law or regulation applicable thereto; provided, however, that the Board may
not, without approval by the shareholders of the Company (i) increase the
maximum number of shares which may be sold under the Plan, except as provided in
Section 12, or (ii) permit the purchase of common stock to anyone other than as
provided in Section 5. Any termination, suspension, revision or amendment of the
Plan may, without the consent of the Purchaser making payments under an approved
deferred payment arrangement, adversely affect the rights of such

                                       3
<PAGE>

Purchaser under such arrangement, provided, that the rights of the Purchaser to
shares that have been fully paid for shall not be affected.

     15.  Indemnification. In addition to such other rights of indemnification
as they may have as shareholders, the Directors of the Board of Directors shall
be indemnified by the Company against all costs and expenses reasonably incurred
by them in connection with any action, suit or proceeding to which they or any
of them may be a party by reason of any action taken or failure to act under or
in connection with the Plan or any purchase granted thereunder, and against all
amounts paid by them in settlement thereof (provided such settlement is approved
by legal counsel selected by the Company) or paid by them in satisfaction of a
judgement in any such action, suit or proceeding, except a judgement based upon
the finding of bad faith; provided that upon the institution of any such action,
suit or proceedings, such member of the Board shall in writing give the Company
notice thereof and an opportunity, at its own expense, to handle and defend the
same before such member undertakes to handle and defend it on his/her own
behalf. Each member of the Board and each officer and employee of the Company
shall be fully justified in relying or acting in good faith upon any information
furnished in connection with the administration of the Plan by any person or
persons other than himself. In no case shall any person who is or shall have
been a member of the Board of an officer or employee of the Company, be liable
for any determination made or any action taken or any omission to act in
reliance upon such information, or for any action (including furnishing of
information) taken or any failure to act, if in good faith.

     16.  Conditions Upon Issuance of Shares. Shares shall not be issued
under the Plan unless the purchase and sale and the issuance and delivery of
such shares pursuant thereto shall comply with all relevant provisions of law,

and regulations promulgated thereunder, and any applicable state securities

State without giving effect to the principles of conflict of laws.

List shall be determined by an independent professional engineer employed by the
mutual agreement of Landlord and Tenant. Notwithstanding the above Punch List
items, if Tenant takes possession of and occupies the Leased Premises, Tenant

the permitting of any such work it performs.

workmanlike manner, and in compliance with all governmental regulations. Tenant
covenants and agrees that all contractors, subcontractors and other persons or

     Tenant hereby indemnifies Landlord against, and shall keep all portions of
the Leased Premises, the Building and the Land free from liens for any work
performed, material furnished or obligations incurred by Tenant. Should any
liens or claims be filed against all or any portion of the Leased Premises, the
Building or the Land by reason of Tenant's acts, omissions or work performed by
any person or entity on behalf of Tenant, Tenant shall cause same to be
discharged by bond or otherwise within thirty (30) days following notice
thereof. If Tenant fails to cause any such lien or claim to be discharged within
the required time, Landlord may cause same to be discharged and may make any
payment that Landlord, in its reasonable judgment, considers necessary,
desirable or proper in order to do so. All amounts paid by Landlord shall bear
interest at the lower of (i) eighteen percent (18%) per annum, or (ii) the
highest rate permitted under applicable law, from the date of payment by
Landlord and shall be payable by Tenant to Landlord upon written demand.

     Notwithstanding the foregoing, Tenant shall be required to obtain
Landlord's prior written consent for any improvements, alterations, additional
or installments upon the Leased Premises as set forth in Section 7.03 herein.

     Section 2.03.  Surrender of the Premises. Upon the expiration or earlier
termination of this Lease, Tenant shall immediately surrender the Leased
Premises to Landlord in broom-clean condition and in good condition and repair,

also remove its personal property, trade fixtures and any of Tenant's
alterations designated by Landlord at the time of approval, promptly repair any
damage caused by such removal, and restore the Leased Premises to the condition
existing prior to the installation of such items. If Tenant fails to do so,
Landlord may restore the Leased Premises to such condition at Tenant's expense,
Landlord may cause all of said property to be removed at Tenant's expense, and
Tenant hereby agrees to pay all the costs and expenses thereby reasonably
incurred. All Tenant property, excluding the raised computer floor, which is not
removed within ten (10) days following Landlord's written demand therefor shall
be conclusively deemed to have been abandoned by Tenant, and Landlord shall be
entitled to dispose of such property at Tenant's cost without thereby incurring
any liability to Tenant. The provisions of this section shall survive the
expiration or other termination of this Lease. It is expressly understood that
Tenant is leasing the Leased Premises with the raised computer floor installed
by Sunguard and acquired by Tenant from Sunguard. Tenant will be required to
remove said floor within forty five (45) days of lease termination and shall
return the Leased Premises to Landlord in the same condition as when rented to
Tenant, with no damage to the Leased Premises caused by such removal.

     Section 2.04.  Holding Over. If Tenant retains possession of the Leased
Premises after the expiration or earlier termination of this Lease, Tenant shall
become a tenant from month to month at twice the Monthly Rental Installment in
effect at the end of the Lease Term, and otherwise upon the terms, covenants and
conditions herein specified, so far as applicable. Acceptance by Landlord of
rent in such event shall not result in a renewal of this Lease, and Tenant shall
vacate and surrender the Leased Premises to Landlord upon Tenant being given
thirty (30) days' prior written notice from Landlord to vacate whether or not
said notice is given on the rent paying date. This Section 2.04 shall in no way
constitute a consent by Landlord to any holding over by Tenant upon the
expiration or earlier termination of this Lease, nor limit Landlord's remedies
in such event.

                                ----------------

     Section 3.01.  Base Rent. Tenant shall pay to Landlord the Minimum Annual
Rent in the Monthly Rental Installments, in advance, without deduction or
offset, beginning on the Commencement Date and on or before the first day of
each and every calendar month thereafter during the Lease Term. The Monthly
Rental Installment for partial calendar months shall be prorated.

     Section 3.02.  Additional Rent. In addition to the Minimum Annual Rent
Tenant shall pay to Landlord for each calendar year during the Lease Term, as
"Additional Rent,": (a) Tenant's Proportionate Share of all costs and expenses
incurred by Landlord during the Lease Term for Operating Expenses for the
Building and common areas (collectively "Common Area Charges"); (b) any increase
in insurance premiums payable by Landlord over the base amount of $.02 per
square foot of rentable area in the Building; and (c) the amount by which all
Real Estate Taxes (as herein defined) for each tax year exceeds $73 per square
foot of rentable area in the Building. The rentable area in the Building is
52,224 square feet.

     "Operating Expenses" shall mean all of Landlord's expenses for operation,
repair and maintenance to keep the common areas of the Building and Park in good
order, condition and repair (including all additional direct costs and expenses
of operation and maintenance of the common areas of the Building and Park which
Landlord reasonably determines it would have paid or incurred during each year
if the Building had been fully occupied), including, but not limited to, any
increase in management or administrative fees which exceed $.25 per square foot
of rentable area in the Building; utilities; storm water discharge fees;
license, permit, inspection and other fees; fees and assessments imposed by any
covenants or owners' association; security services; and maintenance (including
snow removal) and repair of exterior lighting and landscaped areas, excluding
capital improvement expenses which are reimbursed by third parties (such as
insurance proceeds and other tenants) and other expenses incurred in connection
with leasing or improvement of other tenant space in the Building. The cost of
any capital improvement shall be amortized over the useful life of such
improvement (as reasonably determined by Landlord), and only the amortized
portion shall be included in Operating Expenses.

     "Real Estate Taxes" shall include any form of real estate tax or assessment
or service payments in lieu thereof, and any license fee, commercial rental tax,
improvement bond or other similar charge or tax (other than inheritance,
personal income or estate taxes) imposed upon the Building or common areas (or
against Landlord's business of leasing the Building) by any authority having the
power to so charge or tax, together with costs and expenses of contesting the
validity or amount of Real Estate Taxes, provided that Tenant gets the benefit
of any reduction or refund obtained thereby, which at Landlord's option may be
calculated as if such contesting work had been performed on a contingent fee
basis (whether charged by Landlord's counsel or representative; provided,
however, that said fees are reasonably comparable to the fees charged for
similar services by others not affiliated with Landlord, but in no event shall
fees exceed thirty-three percent (33%) of the good faith estimated tax savings).
Additionally, Tenant shall pay, prior to delinquency, all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all personal property
of Tenant contained in the Leased Premises.

     Section 3.03.  Payment of Additional Rent. Landlord shall estimate the
total amount of Additional Rent to be paid by Tenant during each calendar year
of the Lease Term, pro-rated for any partial years. Commencing on the
Commencement Date, Tenant shall pay to Landlord each month, at the same time the
Monthly Rental Installment is due, an amount equal to one-twelfth (1/12) of the
estimated Additional Rent for such year. Within a reasonable time after the end
of each calendar year, Landlord shall submit to Tenant a certified statement of
the actual amount of such Additional Rent and within thirty (30) days after
receipt of such statement, Tenant shall pay any deficiency between the actual
amount owed and the estimates paid during such calendar year. In the event of
overpayment, Landlord shall credit the amount of such overpayment toward the
next installments of Additional Rent or if this Lease has expired or terminated,
refund the amount of such overpayment within thirty (30) days.

     Notwithstanding the foregoing, Tenant shall, at its sole cost and expense,
during the term of this Lease, have the option to review Landlord's books and
records relating to the Additional Rent. Such review must be completed within
thirty (30) days of receipt of final statement. In the event of any errors
discovered by such review, the appropriate party shall make a correction payment
in full to the other party within thirty (30) days after the determination and
communication to both parties of the amount of such error.

     Section 3.04.  Late Charges. Tenant acknowledges that Landlord shall incur
certain additional unanticipated administrative and legal costs and expenses if
Tenant fails to timely pay any payment required hereunder. Therefore, in
addition to the other remedies available to Landlord hereunder, if any payment
required to be paid by Tenant to Landlord hereunder shall become overdue by more
than five (5) days, such unpaid amount shall bear interest from the due date
thereof to the date of payment at the annual prime rate (as reported in the Wall
Street Journal) of interest ("Prime Rate") plus six percent (6%) per annum.

                          ARTICLE 4 - SECURITY DEPOSIT
                          ----------------------------

     Upon execution of this Lease, Tenant shall deposit with Landlord an amount
such that Landlord shall have as a security deposit a sum equal to the last
month's Monthly Rental Installment. Landlord shall transfer Tenant's Security
Deposit from the existing lease between Eclipse Computer Systems, Inc. and Weeks
Realty, L.P., predecessor to Landlord, for the space commonly known as 1327
Northmeadow Parkway, Suite 132, Roswell, Georgia ("Old Premises"), as security
for the performance by Tenant of all of Tenant's obligations contained in this
Lease. In the event of a default by Tenant Landlord may apply all or any part of
the Security Deposit to cure all or any part of such default; and Tenant agrees
to promptly, upon demand, deposit such additional sum with Landlord as may be
required to maintain the full amount of the Security Deposit. All sums held by
Landlord pursuant to this section shall be held in an interest bearing account
with a major national or regional bank located in Atlanta, Georgia. All interest
earned thereon shall be the property of Tenant and shall be paid to Tenant upon
termination or expiration of this Lease. At the end of the Lease Term, provided
that there is then no uncured default, Landlord shall return the Security
Deposit to Tenant.

                                 ---------------

     Section 5.01.  Use of Leased Premises. The Leased Premises are to be used
by Tenant solely for the Permitted Use and for no other purposes without the
prior written consent of Landlord, which consent shall not be unreasonably
withheld, delayed or conditioned.

     Section 5.02.  Covenants of Tenant Regarding Use. Tenant shall (i) use and
maintain the Leased Premises and conduct its business thereon in a safe,
careful, reputable and lawful manner, (ii) comply with all laws, rules,
regulations, orders, ordinances, directions and requirements of any governmental
authority or agency, now in force or which may hereafter be in force, including
without limitation those which shall impose upon Landlord or Tenant any duty
with respect to or triggered by a change in the use or occupation of, or any
improvement or alteration to, the Leased Premises, (iii) any protective
covenants applicable to the Park which are in effect and as may hereafter be
adopted and promulgated of which Tenant has received written notice and (iv)
comply with and obey all reasonable directions of the Landlord, including any
reasonable rules and regulations that may be adopted by Landlord from time to
time of which Tenant has received written notice. Tenant shall not do or permit
anything to be done in or about the Leased Premises or common areas which will
in any way obstruct or interfere with the rights of other tenants or occupants
of the Building or injure or annoy them. Landlord shall not be responsible to
Tenant for the nonperformance by any other tenant or occupant of the Building of
its lease or of any rules and regulations provided however, that Landlord shall
enforce the rules and regulations in a non-discriminatory fashion. Tenant shall
not overload the floors of the Leased Premises. All damage to the floor
structure or foundation of the Building due to improper positioning or storage
of items or materials shall be repaired by Landlord at the sole expense of
Tenant, who shall reimburse Landlord immediately therefor upon demand. Tenant
shall not use the Leased Premises, or allow the Leased Premises to be used, for
any purpose or in any manner which would invalidate any policy of insurance now
or hereafter carried on the Building or increase the rate of premiums payable on
any such insurance policy unless Tenant reimburses Landlord as Additional Rent
for any increase in premiums charged. On or before the Commencement Date, Tenant
shall take possession of, and, thereafter, continuously occupy the Leased
Premises during the term of this Lease, and operate thereon the normal business
operations of Tenant.

     Section 5.03.  Landlord's Rights Regarding Use. In addition to the rights
specified elsewhere in this Lease, Landlord shall have the following rights
regarding the use of the Leased Premises or the common areas, each of which may
be exercised without notice or liability to Tenant, (a) Landlord may install
such signs, advertisements, notices or tenant identification information as it
shall deem necessary or proper; (b) Landlord shall have the right at any time to
control, change or otherwise alter the common areas as it shall deem necessary
or proper, provided that Landlord shall not reduce the number of tenant parking
spaces; and (c) Landlord or Landlord's agent shall be permitted to inspect or
examine the Leased Premises at any reasonable time upon reasonable notice
(except in an emergency when no notice shall be required), and Landlord shall
have the right to make any repairs to the Leased Premises which are necessary
for its preservation; provided, however, that any repairs made by Landlord shall
be at Tenant's expense, except as provided in Section 7.02 hereof. Landlord
shall incur no liability to Tenant for such entry, nor shall such entry
constitute an eviction of Tenant or a termination of this Lease, or entitle
Tenant to any abatement of rent therefor.

                       ----------------------------------

     Tenant shall obtain in its own name and pay directly to the appropriate
supplier the cost of all utilities and services serving the Leased Premises.
However, if any services or utilities are jointly metered with other property,
Landlord shall make a reasonable determination of Tenant's proportionate share
of the cost of such utilities and services without any premium to Landlord and
Tenant shall pay such share to Landlord within fifteen (15) days after receipt
of Landlord's written statement delivered by registered or certified mail.
Landlord shall not be liable in damages or otherwise for any failure or
interruption of any utility or other Building service and no such failure or
interruption shall entitle Tenant to terminate this Lease or withhold sums due
hereunder. In the event of utility "deregulation", Landlord shall choose the
service provider.

                       ARTICLE 7 - MAINTENANCE AND REPAIRS
                       -----------------------------------

     Section 7.01.  Tenant's Responsibility. During Lease Term, Tenant shall, at
its own cost and expense, maintain the Leased Premises in good condition,
regularly servicing and promptly making all repairs thereto, including but not
limited to the electrical systems, heating and air conditioning systems, plate
glass, windows and doors, and shall obtain a preventive maintenance contract on
the heating, ventilating and air-conditioning systems serving the Leased
Premises (hereinafter referred to as "HVAC System"), and provide Landlord with a
copy thereof. The preventive maintenance contract shall meet or exceed
Landlord's standard maintenance criteria, and shall provide for the inspection
and maintenance of the HVAC System on not less than a semi-annual basis. In the
event Tenant fails to maintain the Leased Premises in any material respect as
required herein or fails to commence repairs (requested by Landlord in writing)
within thirty (30) days after such request, or fails diligently to proceed
thereafter to complete such repairs, Landlord shall have the right in order to
preserve the Leased Premises or portion thereof, and/or the appearance thereof,
to make such repairs or have a contractor make such repairs and charge Tenant
for the cost thereof as additional rent, together with interest at the rate of
eight percent (8%) per annum from the date of making such payments. Provided
however, at Landlord's sole expense, Landlord agrees to hire Shumate Mechanical
to inspect the HVAC system and to cause it to be in excellent working order at
lease commencement and at its cost and expense make, any repairs or replacements
of the HVAC system required during the first twelve (12) months of the Lease
term, except any repairs necessary because of Tenant's negligent or tortuous
actions or omissions. During the term of the Lease, Tenant agrees to reimburse
Landlord for a fraction of the replacement cost of any compressor equal to the
number of years remaining on the Lease divided by the useful life of the HVAC
compressor.

     Section 7.02.  Landlord's Responsibility. During Lease Term, Landlord shall
maintain in good condition and repair, and replace as necessary, the roof,
exterior walls, foundation and structural frame of the Building and the parking
and landscaped areas, the costs of which shall not be included in Operating
Expenses; provided, however, that to the extent any of the foregoing items
require repair because of the negligence, misuse, or default of Tenant, its
employees, agents, customers or invitees, Landlord shall make such repairs
solely at Tenant's expense.

<PAGE>

     Section 7.03.  Alterations. Tenant shall not permit alterations in or to
the Leased Premises unless and until the plans and the contractor have been
approved by Landlord in writing. As a condition of such approval, Landlord may
require Tenant to remove the alterations and restore the Leased Premises upon
termination of this Lease (if Landlord notifies Tenant of such removal
requirement at the time of Landlord's approval of such alteration); otherwise,
all such alterations shall at Landlord's option become a part of the realty and
the property of Landlord, and shall not be removed by Tenant. Tenant shall
ensure that all alterations shall be made in accordance with all applicable
laws, regulations and building codes, in a good and workmanlike manner and of
quality equal to or better than the original construction of the Building. Upon
completion of the work, Tenant shall provide lien waivers from the
subcontractors or a final affidavit of lien waiver from the general contractor,
and such lien waiver shall be in a form acceptable to Landlord. No person shall
be entitled to any lien derived through or under Tenant for any labor or
material furnished to the Leased Premises, and nothing in this Lease shall be
construed to constitute a consent by Landlord to the creation of any lien. If
any lien is filed against the Leased Premises for work claimed to have been done
for or material claimed to have been furnished to Tenant, Tenant shall cause
such lien to be discharged of record or by bond or other security or title
indemnity within thirty (30) days after filing. Tenant shall indemnify Landlord
from all reasonable costs, losses, expenses and attorneys' fees in connection
with any construction or alteration and any related lien. Landlord hereby
confirms that it has approved the alterations proposed by Tenant to construct a
data center including, without limitation, the installation of additional raised
flooring, upgraded wiring, a security system and a fire safety system and diesel
generators, all of which shall be removed by Tenant upon expiration or earlier
termination of this Lease.

                              ARTICLE 8 - CASUALTY
                              --------------------

     Section 8.01.  Casualty. In the event of total or partial destruction of
the Building or the Leased Premises by fire or other casualty, Landlord agrees
to promptly restore and repair the Leased Premises; provided, however,
Landlord's obligation hereunder shall be limited to the reconstruction of such
of the tenant finish improvements as were originally provided by Landlord, if
any. Rent shall proportionately abate during the time that the Leased Premises
or part thereof are unusable because of any such damage. Notwithstanding the
foregoing, if the Leased Premises are (i) so destroyed that they cannot be
repaired or rebuilt within one hundred eighty (180) days from the casualty date;
or (ii) destroyed by a casualty which is not covered by the insurance required
hereunder or, if covered, such insurance proceeds are not released by any
mortgagee entitled thereto or, together with the amount of any deductible, are
insufficient to rebuild the Building and the Leased Premises; then, in case of a
clause (i) casualty, either Landlord or Tenant may, or, in the case of a clause
(ii) casualty, then Landlord may, upon thirty (30) days' written notice to the
other party, terminate this Lease, effective as of the date of such fire or
other casualty with respect to matters thereafter accruing. Tenant waives any
right under applicable laws inconsistent with the terms of this paragraph and in
the event of a destruction agrees to accept any offer by Landlord to provide
Tenant with comparable space within the project in which the Leased Premises are
located on the same terms as this Lease. Notwithstanding the provisions of this
paragraph, if any such damage or destruction occurs within the final two (2)
years of the term hereof, then Landlord, in its sole discretion, may, without
regard to the aforesaid 180-day period, terminate this Lease by written notice
to Tenant.

     Section 8.02.  All Risk Coverage Insurance. During the Lease Term, Landlord
shall maintain all risk coverage insurance on the Building, but shall not
protect Tenant's property on the Leased Premises; and, notwithstanding the
provisions of Section 9.01, Landlord shall not be liable for any damage to
Tenant's property, regardless of cause, which is covered by Tenant's personal
property insurance, including the negligence of Landlord and its employees,
agents and invitees. Tenant hereby expressly waives any right of recovery
against Landlord for damage to any property of Tenant located in or about the
Leased Premises, which is covered by Tenant's personal property insurance,
however caused, including the negligence of Landlord and its employees, agents
and invitees. Notwithstanding the provisions of Section 9.01 below, Landlord
hereby expressly waives any rights of recovery against Tenant for damage to the
Leased Premises or the Building which is insured against under Landlord's all
risk coverage insurance. All insurance policies maintained by Landlord or Tenant
as provided in this Lease shall contain an agreement by the insurer waiving the
insurer's right of subrogation against the other party to this Lease.

                         ARTICLE 9 - LIABILITY INSURANCE
                         -------------------------------

     Section 9.01.  Tenant's Responsibility. Landlord shall not be liable to
Tenant or to any other person for (i) damage to property or injury or death to
persons due to the condition of the Leased Premises, the Building or the common
areas, or (ii) the occurrence of any accident in or about the Leased Premises or
the common areas, or (iii) any act or neglect of Tenant or any other tenant or
occupant of the Building or of any other person, unless such damage, injury or
death is directly and solely the result of Landlord's negligence; and Tenant
hereby releases Landlord from any and all liability for the same. Tenant shall
be liable for, and shall indemnify and defend Landlord from, any and all
liability for (i) any act or neglect of Tenant and any person coming on the
Leased Premises or common areas by the license of Tenant, express or implied,
(ii) any damage to the Leased Premises, and (iii) any loss of or damage or
injury to any person (including death resulting therefrom) or property occurring
in, on or about the Leased Premises, regardless of cause, except for any loss or
damage covered by Landlord's all risk coverage insurance as provided in Section
8.02 and except for that caused solely and directly by Landlord's or its agent's
or employee's negligence. This provision shall survive the expiration or earlier
termination of this Lease.

     Section 9.02.  Tenant's Insurance.  Tenant shall carry general public
liability and property damage insurance, issued by one or more insurance
companies acceptable to Landlord, with the following minimum coverages:

A.   Worker's Compensation: minimum statutory amount.

B.   Commercial General Liability Insurance, including blanket, contractual
     liability, broad form property damage, personal injury, completed
     operations, products liability, and fire damage: Not less than $3,000,000
     Combined Single Limit for both bodily injury and property damage.

                                      -11-

<PAGE>

C.   All Risk Coverage, Vandalism and Malicious Mischief, and Sprinkler Leakage
     insurance, if applicable, for the full cost of replacement of Tenant's
     property.

D.   Business interruption insurance.

The insurance policies shall protect Tenant and Landlord as their interests may
appear, naming, Landlord and Landlord's managing agent and mortgagee as
additional insureds, and shall provide that they may not be canceled on less
than thirty (30) days' prior written notice to Landlord. Tenant shall furnish
Landlord with Certificates of Insurance evidencing all required coverages on or
before the Commencement Date. If Tenant fails to carry such insurance and
furnish Landlord with such Certificates of Insurance within fifteen (15) days
after a request to do so, Landlord may obtain such insurance and collect the
reasonable cost thereof from Tenant.

                           ARTICLE 10 - EMINENT DOMAIN
                           ---------------------------

     If all or any substantial part of the Building or common areas shall be
acquired by the exercise of eminent domain, Landlord may terminate this Lease by
giving written notice to Tenant on or before the date that actual possession
thereof is so taken. If all or any part of the Leased Premises or access to the
Leased Premises shall be acquired by the exercise of eminent domain so that the
Leased Premises shall become impractical for Tenant to use for the Permitted
Use, Tenant may terminate this Lease as of the date that actual possession
thereof is so taken by giving written notice to Landlord. All damages awarded
shall belong to Landlord; provided, however, that Tenant may claim dislocation
damages if such amount is not subtracted from Landlord's award.

                      ARTICLE 11 - ASSIGNMENT AND SUBLEASE
                      ------------------------------------

     Tenant shall not assign this Lease or sublet the Leased Premises in whole
or in part without Landlord's prior written consent, which consent shall not be
unreasonably withheld, delayed or denied (provided that it shall not be
unreasonable for Landlord to withhold or deny its consent with respect to any
proposed assignment or subletting to a third party that is already a tenant in
the Building or the Park). In the event Landlord consents to the assignment or
sublease, Landlord shall notify Tenant within ten (10) business days of receipt
of written notice by Tenant of its intent to assign or sublease. In the event of
any assignment or subletting, Tenant shall remain primarily liable hereunder,
and any extension, expansion, rights of first offer, rights of first refusal or
other options granted to Tenant under this Lease shall be rendered void and of
no further force or effect. The acceptance of rent from any other person shall
not be deemed to be a waiver of any of the provisions of this Lease or to be a
consent to the assignment of this Lease or the subletting of the Leased
Premises. Without in any way limiting Landlord's right to refuse to consent to
any assignment or subletting of this Lease, Landlord reserves the right to
refuse to give such consent if in Landlord's opinion (i) the Leased Premises are
or may be in any way materially adversely affected; (ii) the business reputation
of the proposed assignee or subtenant is unacceptable; or (iii) the financial
worth of the proposed assignee or subtenant is insufficient to meet the
obligations hereunder. Landlord further expressly reserves the right to refuse
to give its consent to any subletting if the proposed rent is to be less than
the then current rent for similar premises in the Park. In the event that Tenant
sublets greater than 33% of the Leased Premises, or assigns this Lease and at
any time receives rent

                                      -12-

<PAGE>

and/or consideration which exceeds that which Tenant would at that time be
obligated to pay to Landlord, Tenant shall pay to Landlord 100% of the gross
excess in such rent as such rent is received by Tenant and 50% of the "net
excess" (as hereinafter defined) of any other consideration received by Tenant
from such subtenant in connection with and solely for such sublease or, in the
case of any assignment of this Lease by Tenant, Landlord shall receive 50% of
any consideration paid to Tenant by such assignee in connection and solely for
with such assignment. Tenant agrees to reimburse Landlord for reasonable
accounting and attorneys' fees incurred in conjunction with the processing and
documentation of any such requested assignment, subletting or any other
hypothecation of this Lease or Tenant's interest in and to the Leased Premises
not to exceed $500.00 per transaction. "Net excess" shall mean gross rent as
reduced by all reasonable expenses of such assignment including commissions,
tenant improvement costs or re-leasing and rent paid by Tenant while the Leased
Premises was unoccupied. Landlord hereby acknowledges that the business to be
conducted by Tenant in the Leased Premises requires the installation of certain
equipment owned by customers of Tenant and third party telecommunications
providers (collectively "Collocators") in order for such Collocators to
interconnect with Tenant's telecommunications facilities in the Leased Premises.
Notwithstanding anything to the contrary contained in the Lease, to expedite
access to the Leased Premises, Landlord agrees that Tenant may license use of a
portion of the Leased Premises to such Collocators, or enter into, Collocation
Agreements with the Collocators without Landlord's prior consent. Collocation
shall not be considered an assignment or sublease for purposes of the Lease and
Landlord shall not have any rights to any portion of Tenant's income therefrom.
Tenant represents and warrants that it will require all Collocators to obtain
appropriate property and general liability insurance covering the full value of
the Collocator's equipment. Tenant agrees to indemnify and hold Landlord
harmless from and against any damage or loss to such Collocator's equipment or
use of the Leased Premises by such Collocators.

                       ARTICLE 12 - TRANSFERS BY LANDLORD
                       ----------------------------------

     Landlord shall have the right to subordinate this Lease to any mortgage
presently existing or hereafter placed upon the Building by so declaring in such
mortgage. In the event of a sale or transfer of such interest (except a mortgage
or other transfer as security for a debt), the "Landlord" named herein, or in
the case of a subsequent transfer, the transferor shall, after the date of such
transfer, be automatically released from all personal liability for the
performance or observance of any term, condition, covenant or obligation
required to be performed or observed by Landlord hereunder after the date of
such transfer, and the transferee shall be deemed to have assumed all of such
terms, conditions, covenants and obligations. Within ten (10) business days
following receipt of a written request from Landlord, Tenant shall execute and
deliver to Landlord, without cost, any instrument which Landlord deems necessary
or desirable to confirm the subordination of this Lease and an estoppel
certificate in such form as Landlord may reasonably request certifying (i) that
this Lease is in full force and effect and unmodified or stating the nature of
any modification, (ii) the date to which rent has been paid, (iii) that there
are not, to Tenant's knowledge, any uncured defaults or specifying such defaults
if any are claimed, and (iv) any other matters or state of facts reasonably
required respecting the Lease. Such estoppel may be relied upon by Landlord and
by any purchaser or mortgagee of the Building. Notwithstanding the foregoing, if
the mortgagee shall take title to the Leased Premises through foreclosure or
deed in lieu of foreclosure, Tenant shall be allowed to

                                      -13-

<PAGE>

continue in possession of the Leased Premises as provided for in this Lease so
long as Tenant shall not be in default after the expiration of any grace or cure
period therefor.

                         ARTICLE 13 - DEFAULT AND REMEDY
                         -------------------------------

     Section 13.01. Default. The occurrence of any of the following shall be a
"Default":

     (a)  Tenant fails to pay any Monthly Rental Installment or Additional
Rent within five (5) days after the same is due, or Tenant fails to pay any
other amounts due Landlord from Tenant within ten (10) days after receipt of
notice that the same is due.

     (b)  Tenant fails to perform or observe any other material term, condition,
covenant or obligation required under this Lease for a period of thirty (30)
days after notice thereof from Landlord; provided, however, that if the nature
of Tenant's default is such that more than thirty days are reasonably required
to cure, then such default shall be deemed to have been cured if Tenant
commences such performance within said thirty-day period and thereafter
diligently completes the required action within a reasonable time.

     (c)  Tenant shall assign or sublet all or a portion of the Leased Premises
in contravention of the provisions of Article 11 of this Lease.

     (d)  All or substantially all of Tenant's assets in the Leased Premises
or Tenant's interest in this Lease are attached or levied under execution (and
Tenant does not discharge the same within sixty (60) days thereafter); a
petition in bankruptcy, insolvency or for reorganization or arrangement is filed
by or against Tenant (and Tenant fails to secure a stay or discharge thereof
within sixty (60) days thereafter); Tenant is insolvent and unable to pay its
debts as they become due; Tenant makes a general assignment for the benefit of
creditors; Tenant takes the benefit of any insolvency action or law; the
appointment of a receiver or trustee in bankruptcy for Tenant or its assets if

if Tenant is a corporation.

     Section 13.02. Remedies. Upon the occurrence of any Default, Landlord shall
have the following rights and remedies, in addition to those allowed by law or
in equity, any one or more of which may be exercised without further notice to
Tenant:

     (a)  Landlord may apply the Security Deposit or re-enter the Leased
Premises and cure any default of Tenant, and Tenant shall reimburse Landlord as
additional rent for any costs and expenses which Landlord thereby incurs; and
Landlord shall not be liable to Tenant for any loss or damage which Tenant may
sustain by reason of Landlord's action.

     (b)  Landlord may terminate this Lease or, without terminating this Lease,
terminate Tenant's right to possession of the Leased Premises as of the date of
such Default, and thereafter (i) neither Tenant nor any person claiming under or
through Tenant shall be entitled to possession of the Leased Premises, and
Tenant shall immediately surrender the Leased Premises to Landlord; and (ii)
Landlord may re-enter the Leased Premises and dispossess Tenant and any other
occupants

                                      -14-

<PAGE>

of the Leased Premises by any lawful means and may remove their effects, without
prejudice to any other remedy which Landlord may have. Upon the termination of
this Lease, Landlord may declare the present value (discounted at the Prime Rate
of interest) of all rent which would have been due under this Lease for the
balance of the Lease Term to be immediately due and payable, whereupon Tenant
shall be obligated to pay the same to Landlord, together with all loss or damage
which Landlord may sustain by reason of Tenant's default ("Default Damages"),
which shall include without limitation reasonable expenses of preparing the
Leased Premises for re-letting, demolition, repairs, tenant finish improvements,
brokers' commissions and attorneys' fees, such payment shall not constitute a
penalty, or forfeiture, but shall constitute full liquidated damages due to
Landlord as a result of Tenant's default. Landlord and Tenant acknowledge that
Landlord's actual damages in the event of a default by Tenant under this Lease
will be difficult to ascertain, and that the liquidated damages provided above
represent the parties' best estimate of such damages. The parties expressly
acknowledge that the foregoing liquidated damages are intended not as a penalty,
but as full liquidated damages, as permitted by Section 13-6-7 of the Official
Code of Ga. Annotated it being expressly understood and agreed that the
liabilities and remedies specified in this subsection (b) shall survive the
termination of this Lease.

     (c)  Landlord may, without terminating this Lease, re-enter the Leased
Premises and re-let all or any part thereof for a term different from that which
would otherwise have constituted the balance of the Lease Term and for rent and
on terms and conditions different from those contained herein, whereupon Tenant
shall be immediately obligated to pay to Landlord as liquidated damages the
difference between the rent provided for herein and that provided for in any
lease covering a subsequent re-letting of the Leased Premises, for the period
which would otherwise have constituted the balance of the Lease Term, together
with all of Landlord's Default Damages.

     (d)  Landlord may sue for injunctive relief or to recover damages for any
loss resulting from the Default.

     Section 13.03. Landlord's Default and Tenant's Remedies. Landlord shall be
in default if it fails to perform any term, condition, covenant or obligation
required under this Lease for a period of thirty (30) days after written notice
thereof from Tenant to Landlord; provided, however, that if the term, condition,
covenant or obligation to be performed by Landlord is such that it cannot
reasonably be performed within thirty (30) days, such default shall be deemed to
have been cured if Landlord commences such performance within said thirty-day
period and thereafter diligently undertakes to complete the same. Upon the
occurrence of any such default, Tenant may sue for injunctive relief or to
recover damages for any loss directly resulting from the breach, but Tenant
shall not be entitled to terminate this Lease or withhold, offset or abate any
sums due hereunder.

     Section 13.04. Limitation of Landlord's Liability. If Landlord shall fail
to perform any term, condition, covenant or obligation required to be performed
by it under this Lease and if Tenant shall, as a consequence thereof, recover a
money judgment against Landlord, Tenant agrees that it shall look solely to
Landlord's right, title and interest in and to the Building for the collection
of such judgment; and Tenant further agrees that no other assets of Landlord
shall be subject to levy, execution or other process for the satisfaction of
Tenant's judgment.

     Section 13.05. Nonwaiver of Defaults. Neither party's failure or delay in
exercising any of its rights or remedies or other provisions of this Lease shall
constitute a waiver thereof or affect its right thereafter to exercise or
enforce such right or remedy or other provision. No waiver of any default shall
be deemed to be a waiver of any other default. Landlord's receipt of less than
the full rent due shall not be construed to be other than a payment on account
of rent then due, nor shall any statement on Tenant's check or any letter
accompanying Tenant's check be deemed an accord and satisfaction. No act or
omission by Landlord or its employees or agents during the Lease Term shall be
deemed an acceptance of a surrender of the Leased Premises, and no agreement to
accept such a surrender shall be valid unless in writing and signed by Landlord.

     Section 13.06. Attorneys' Fees. If either party defaults in the performance
or observance of any of the terms, conditions, covenants or obligations
contained in this Lease and the non-defaulting party obtains a judgment against
the defaulting party, then the defaulting party agrees to reimburse the
non-defaulting party for reasonable attorneys' fees incurred in connection
therewith.

Landlord, at its expense, with improvements at least equal in quantity and
quality to those in the Leased Premises. Landlord shall reimburse Tenant for all
reasonable expenses incurred with and caused by such relocation. In no event
shall Landlord be liable to Tenant for any consequential damages as a result of
any such relocation, including, but not limited to, loss of business income or
opportunity. Such right shall not be exercised more than once during the Lease
term.

with a Phase I Environmental Assessment of the Leased Premises, prepared by
Atlanta Testing and Engineering and dated October 19, 1993, and updated on June

respects. To the best knowledge of Landlord, the Leased Premises and its
existing and prior uses and activities thereon, including but not limited to the
use, maintenance and operation of the Leased Premises and all activities and
conduct of business related to it, have complied with all federal, state and
local environmental laws, ordinances and regulations. The Landlord has never
received any notice or other communications concerning any alleged material
violation of any environmental laws or regulations affecting the Leased
Premises. Landlord represents and warrants that there are no underground storage
tanks on the Leased Premises. Tenant, at its sole cost and expense, shall
promptly comply with the Environmental Laws including any notice from any source
issued pursuant to the Environmental Laws or issued by any insurance company

Landlord of (i) any violation by Tenant, its employees, agents, representatives,
customers, invitees or contractors of the Environmental Laws on, under or about

suspected presence of any Hazardous Substances on, under or about the Leased
Premises and shall immediately deliver to Landlord any notice received by Tenant
relating to (i) and (ii) above from any source. Tenant shall execute affidavits,
representations and the like within five (5) days of Landlord's request therefor
concerning Tenant's knowledge and belief without extraordinary inquiry or
investigation regarding the presence of any Hazardous Substances on, under or
about the Leased Premises.

     Section 15.05. Landlord's Rights. Landlord and its agents shall have the
right, but not the duty, upon advance notice (except in the case of emergency
when no notice shall be required) to inspect the Leased Premises and conduct
tests thereon to determine whether or the extent to which there has been a
violation of Environmental Laws by Tenant or whether there are Hazardous
Substances on, under or about the Leased Premises. In exercising its rights
herein, Landlord shall use reasonable efforts to minimize interference with
Tenant's business but such entry shall not constitute an eviction of Tenant, in
whole or in part, and Landlord shall not be liable for any interference, loss,
or damage to Tenant's property or business caused thereby.

contained in this Article 15 to the contrary, Tenant shall not have any
liability to Landlord under this Article 15 resulting from any conditions
