                  Sublandlord to enforce one or more of the remedies upon an
                  event of default shall not constitute a waiver of such
                  default.

11.      PEACEFUL ENJOYMENT.

         Subtenant shall, and may peacefully enjoy the Subleased Premises
         against all persons claiming by, through or under Sublandlord, subject
         to the other terms hereof, provided that Subtenant pays the rent and
         other sums herein recited to be paid by Subtenant and performs all of
         Subtenant's covenants and agreements in this Sublease Agreement.

12.      HOLDING OVER.

         12.1     RENTAL AMOUNT. If Subtenant holds over without Sublandlord's
                  or Owner's written consent after expiration or other
                  termination of this Sublease Agreement, or if Subtenant
                  continues to occupy the Subleased Premises after termination
                  of Subtenant's right of possession, Subtenant shall
                  throughout the entire holdover period pay rent at a rate
                  equal to the greater of (a) two (2) times the Basic Rent paid
                  by Subtenant during the last preceding Lease Year; or (b)
                  rent, damages and expenses owed to the Owner by the
                  Sublandlord arising as a result of Subtenant's holding over.

         12.2     NO EXTENSION OF TERM. No possession by Subtenant after the
                  expiration of the term of this Sublease Agreement shall be
                  construed to extend the term of this Sublease Agreement
                  unless Sublandlord has consented to such possession in
                  writing.

13.      ATTORNEY'S FEES.

         In any legal or other proceeding which Sublandlord or Subtenant may
         pursue to enforce its rights hereunder, the unsuccessful or
         non-prevailing party shall pay all costs incurred by the successful or
         prevailing party in such action, including court costs and reasonable
         attorneys' fees, whether such fees and costs be incurred out of court,
         at trial, on appeal or in bankruptcy proceedings.

14.      PERSONAL LIABILITY.

         Except as to the timely and full performance by Sublandlord of its
         obligations and responsibilities to (a) remit all of Subtenant's rent
         payments and other amounts received hereunder by Sublandlord to the
         Primary Landlord, and (b) remit to the Primary Landlord the balance of
         rents and other amounts due under the Primary Lease which are in
         excess of rents due under this Sublease from Subtenant, and (c)

         any further liability of Sublandlord to Subtenant for any default by
         Sublandlord under this Sublease Agreement shall be limited to the
         interest of Sublandlord in the Subleased Premises, and Subtenant
         agrees to look solely to Sublandlord's interest in the Subleased
         Premises for the recovery of any judgment from the Sublandlord, it
         being intended that Sublandlord shall not be personally liable for any
         judgment or deficiency.

15.      RELATIONSHIP OF PARTIES.

         Nothing contained in this Sublease Agreement shall be deemed or
         construed by the parties hereto, nor by any third party, as creating
         the relationship of principal and agent or of partnership or of joint
         venture between the parties hereto, it being understood and agreed
         that neither the method of computation of rent, nor any other
         provisions contained herein, nor any acts of the parties herein, shall
         be deemed to create any relationship between the parties hereto other
         than the relationship of Sublandlord and Subtenant.

16.      MISCELLANEOUS.

         16.1     SEVERABILITY. If any term or provision of this Sublease
                  Agreement, or the application thereof to any person or

                  Sublandlord and Cushman & Wakefield of Florida, Inc.
                  represents the Subtenant (collectively the "Real Estate
                  Brokers") on the Sublease. Sublandlord shall pay the Real
                  Estate Brokers a commission on this transaction in accordance
                  with a separate agreement. Subtenant and Sublandlord each

                  indemnify and agree to hold each other harmless against any

                  commissions or brokerage fees that may be claimed by such

                  responsibilities which have been specifically modified by the
                  provisions included in this Sublease, which Sublease
                  provisions shall control in the event of any conflict between

                                  CORNERSTONE


This Lease is dated as of July 31, 1977 by and between TALCOTT REALTY I LIMITED
PARTNERSHIP, a Connecticut limited partnership, having an office at Hartford,
Connecticut (Landlord), and MEDPARTNERS ACQUISITION CORPORATION, a Delaware
corporation, having an office at Birmingham, Alabama (Tenant). Landlord's
predecessor-in-interest, Hartford Fire Insurance Company, and Tenant's
predecessor-in-interest, Emergency Medical Services Associates, Inc., entered
into a lease dated March 16, 1992, as amended, for a portion of the Premises
(Original Lease). Landlord and Tenant have agreed to expand the Premises and
change the termination date and other material terms of the Original Lease. The
parties deem it appropriate to replace the Original Lease with this restated
Lease and, upon the Initial Space Commencement Date hereof, the Original Lease
shall terminate as if that date were the termination date originally stated in
the Original Lease.


                             I. DEMISE OF PREMISES

Landlord hereby leases to Tenant and Tenant leases from Landlord the Premises
located in the Building, together with the nonexclusive right to use, in common
with Landlord and others, the following portions of the Building and Land: the
entrance foyer and lobby; the stairways, elevators, shipping and receiving
areas; the exterior sidewalks and driveways; and the corridors and lavatories
on the floors on which the Premises are situated; provided, however, so long as
Tenant shall occupy the entire 5th floor, the entire 6th floor and/or the
entire 8th floor of the Building, Tenant shall have the exclusive use of the
corridors and lavatories on each such full floor so occupied by Tenant, which
exclusive use shall, notwithstanding the previous provision, be subject to
Landlord's rights of use and access hereunder.


                             II. SUMMARY OF TERMS

As used in this Lease, the following terms shall have the following meanings:

A.       PREMISES: That part of the Building outlined on the attached Plan
         showing the Premises, called Suites 150, 500, 600, 700, 770 on the
         1st, 5th, 6th and 7th floors of the Building (Initial Space) and Suite
         800 on the 8th floor of the Building (Suite 800), including all tenant
         improvements in existence at the execution date of this Lease. Tenant
         is accepting the Premises in an "as is" condition; Landlord shall have
         no responsibility for making any tenant improvements to the Premises,
         except that Landlord shall remove the phone and computer lines and the
         demountable walls existing in Suite 800 as of the date hereof.



<PAGE>   13
 1.       At the date of any notice required herein, if this Lease shall be in
full force and effect and if Tenant named herein shall be in occupancy of at
least 90 percent of the Premises and shall not be in default of any of the
provisions of this Lease, Tenant may lease certain additional space on the 4th
floor of the Budding, designated "Expansion Space" on the Plan showing the
Expansion Space, commencing on a date to be determined by Landlord in its
reasonable discretion, giving due consideration to then current circumstances,
including items such as the time needed to construct tenant improvements, for a
term to expire at the Termination Date. The base rent, improvement allowance,
and all other fees and charges for the Expansion Space shall be at the market
rate for the Building then being offered by Landlord for like space and for such
a term Market Rate). If Tenant desires to exercise its option to lease the
Expansion Space, it must give Landlord notice of exercise (Expansion Space
Notice) not earlier than May 1, 1999 and not later than October 31, 1999
(Expansion Space Notice Window). Within 15 days after Landlord's receipt of the
Expansion Space Notice, Landlord shall deliver to Tenant a notice setting forth
the Market Rate for the Expansion Space (Expansion Space Market Rate Notice).
Tenant shall approve or disapprove the Market Rate within 15 days after Tenant's
receipt of the Expansion Space Market Rate Notice (Expansion Space Approval
Period). If Tenant approves the Market Rate within the Expansion Space Approval
Period (by notice to Landlord), the Parties shall enter into either a
supplemental agreement to this Lease incorporating the Expansion Space as part
of the Premises or, at Landlord's option, a separate lease agreement. If Tenant
fails to approve the Market Rate within the Expansion Space Approval Period
(either by notice of disapproval or by failing to give any such notice), then
this option shall be void and Tenant shall have no further option to lease the
Expansion Space except as set forth in Section II.A.2.; provided, however, if
Tenant disapproves the Market Rate, Tenant can avoid termination of this option
by giving Landlord notice (Appraisal Notice) within the Approval Period that
Tenant elects to determine the Market Rate by appraisal. The appraisal shall be
made as follows:

                  (a)      The Appraisal Notice must contain the name of the
         appraiser appointed by Tenant to determine the Market Rate. Within 15
         days after Landlord receipt of the Appraisal Notice, Landlord shall
         give Tenant notice of the name of the appraiser appointed by Landlord
         to determined the Market Rate. The two appraisers so appointed shall
         promptly appoint a third appraiser; if they fail to appoint such third
         appraiser within 15 days after they receive notice of their joint
         appointment, then either Landlord or Tenant, upon notice to the other,
         may request the assignment of a third appraiser by the then President
         of the local chapter of the American Institute of Real Estate
         Appraisers. All appraisers shall have at least 10 years experience and
         be familiar with commercial office rentals in buildings comparable to
         the Building in the Plantation area.

                  (b)      The 3 appraisers shall jointly establish the Market
         Rate within 30 days after the appointment of the third appraiser and
         if they cannot agree, the average of the 2 closest estimates will be
         accepted by the parties as the Market Rate, unless the average of all
         3 estimates equals one of the 3 estimates, in which case such average
         estimate shall be accepted by the parties as the Market Rate.



<PAGE>   14

                  (c)      If Landlord fails to appoint an appraiser within the
         period permitted above, then the appraiser appointed by Tenant shall
         have the power to proceed as sole appraiser to establish the Market
         Rate.

                  (d)      Landlord and Tenant shall each pay the fees of the
         appraiser appointed by it and one-half of the fees of the third
         appraiser and the general expenses of the appraisal except that Tenant
         may elect to reject the Market Rate, and if Tenant does so reject,
         then Tenant shall pay the fees of all three appraisers and the general
         expenses of the appraisal and this option shall be void.

                  (e)      After determination of the Market Rate, the parties
         shall execute an agreement, in form reasonably satisfactory to both,
         modifying the Premises, the Base Rent, the Monthly Installments of
         Base Rent, Tenant's Proportionate Share and all other relevant
         matters.

2.       Subject to existing rights under leases of space in the Building as of
the date hereof, and subject to renewals of leases or extensions of terms of
leases of existing tenants of the Additional Office Space (as hereinafter
defined) in Landlord's sole discretion, if at the date of any notice required
herein this Lease shall be in full force and effect and Tenant named herein
shall be in occupancy of at least 90 percent of the Premises and shall not be
in default of any of the provisions of this Lease, Landlord shall notify Tenant
(Landlord's Refusal Space Notice) of the availability of any portion (or all)
of the Expansion Space or certain additional office space on the 4th and 7th
floors of the Building, indicated as "Additional Office Space" on the attached
Plan showing the Additional Space (the space delineated in Landlord's Refusal
Space Notice is referred to as Refusal Space). Landlord's Refusal Space Notice
shall include the base rent, improvement allowance, and all other fees and
charges for the Refusal Space which shall be at the Market Rate. If Tenant
desires to exercise its option to lease the Refusal Space, Tenant shall approve
or disapprove the Market Rate within 15 days after Tenant's receipt of
Landlord's Refusal Space Notice (Refusal Space Approval Period). If Tenant
approves the Market Rate within the Refusal Space Approval Period (by notice to
Landlord), the parties shall enter into either a supplemental agreement to this
Lease incorporating the Refusal Space as part of the Premises or, at Landlord's
option, a separate lease agreement. If Tenant fails to approve the Market Rate
within the Refusal Space Approval Period (either by notice of disapproval or by
failing to give any such notice), then this option shall be void and Tenant
shall have no further option to lease the Refusal Space; provided, however, if
Tenant disapproves the Market Rate, Tenant can avoid termination of this option
by giving Landlord an Appraisal Notice within the Refusal Space Approval Period
Tenant elects to determine the Market Rate by that appraisal. The appraisal
shall be made in accordance with Section II.A.1. above.

         (1)      The commencement date for the Initial Space (Initial Space
         Commencement Date) shall be August 1, 1997.

         (2)      The commencement date for Suite 800 (Suite 800 Commencement
         Date) shall be the later of August 1, 1997 or that date on which
         Landlord delivers possession of Suite 800 to Tenant. Sections l(a) and

G.       TERMINATION DATE: July 31, 2002, unless extended as provided in this
         Lease. At the date of any notice required herein, if this Lease shall
         be in full force and effect and if Tenant named herein shall occupy
         the entire premises and shall not be in default of any of the material
         provisions of this lease, Tenant may extend the Term for an additional
         term of 5 years. The Base Rent and all other fees and charges during
         the extended Term shall be at the Market Rate. Notwithstanding the
         foregoing, no allowance shall be provided to Tenant for improvements
         to the Premises; for purposes of determining the Base Rent for the
         extended Term, however, the Market Rate shall be deemed to include a
         standard allowance. Tenant shall be responsible for any commission or
         fee due to any broker or other agent employed by Tenant. If Tenant
         desires to exercise its option to extend the Term, it must give
         Landlord notice of exercise (Extension Notice) not more than 12 months
         and not less than 6 months prior to the Termination Date (Notice
         Window). Within 15 days after Landlord's receipt of the Extension
         Notice, Landlord shall deliver to Tenant a notice setting forth the
         Market Rate for the extended Term (Market Rate Notice). Tenant shall
         approve or disapprove the Market Rate within 30 days after Tenant's
         receipt of the Market Rate Notice (Approval Period). If Tenant
         approves the Market Rate within the Approval Period (by notice to
         Landlord), the parties shall execute an amendment to this Lease, in
         form reasonably satisfactory to both, modifying the Termination Date,
         the Base Rent, the Monthly Installments of Base Rent and all other
         relevant matters. Tenant's occupancy during the extended Term shall be
         governed by the same provisions of this Lease, except as otherwise
         provided in this Section. If Tenant fails to deliver the Extension
         Notice during the Notice Window or fails to approve the Market Rate
         within the Approval Period (either by notice of disapproval or by
         failing to give any such notice), then this option shall be void and
         Tenant shall have no further option to extend the Term; provided,
         however, if Tenant disapproves the Market Rate, Tenant can avoid
         termination of this option by giving Landlord notice (Appraisal
         Notice) within the Notice Window that Tenant elects to determine the
         Market Rate by appraisal. The appraisal shall be made in accordance
         with Section II.A.1. After determination of the Market Rate, the
         parties shall execute an



<PAGE>   16

         agreement, in form reasonably satisfactory to both, modifying the Base
         Rent, the Monthly Installments of Base Rent and all other relevant
         matters.

2.       If the Term has been extended in accordance with Section II.G.1,

the same procedures and subject to the same conditions as provided in Section
II.G.1. Tenant shall have no further option to extend the Term.

H.       LEASE YEAR: A 12 month period, the first of which shall commence on

         (a)      The Premises shall be deemed substantially completed upon the
issuance of a certificate of substantial completion by Landlord's architect or
a certificate of occupancy by the local building authority, notwithstanding
that minor or insubstantial details of construction, mechanical adjustment or
decoration remain to be performed. If the substantial completion of the
Premises by Landlord is delayed in any way by Tenant or Tenant's
Representatives, the Premises shall be deemed substantially completed for
purposes of this Section on the date when they would have been substantially
completed but for such delay.

         (b)      Tenant's taking possession of the Premises shall be
conclusive evidence that the Premises were in good order, condition and repair
when Tenant took possession, except for those matters (for which Landlord is
responsible as provided in this Lease) of which Tenant gives Landlord notice
within 10 days after taking possession. Landlord shall complete or repair such
matters as soon as reasonably possible.

         (c)      If Landlord is unable to deliver possession of the Premises
to Tenant within 180 days after the Expected Commencement Date (the Outside

described in Section 1(a). Landlord shall not be liable to Tenant or any third
party for its failure to deliver possession of the Premises to Tenant. If the
Commencement Date does not occur within one year after the Expected
Commencement Date, this Lease shall terminate and Landlord and Tenant shall
have no further obligations to the other, except as may otherwise be provided
in this Lease.

         (d)      After the Commencement Date has been determined, Landlord and
Tenant shall execute a supplemental agreement specifying the Commencement Date,
Termination Date and such other information as Landlord shall reasonably
require.

agrees to pay and any other sum payable by Tenant pursuant to this Lease shall
be deemed additional rent (together with Base Rent referred to as the Rent).

cost of all repairs and alterations to the Building's mechanical and electrical
systems (including the installation of meters) and the cost of the additional
electricity made available to Tenant, if any. Tenant shall pay such costs
within 10 days of Landlord's demand therefor and as periodically billed to
Tenant thereafter.

         (d)      Landlord does not warrant that the services supplied by
Landlord will be free from interruption. any interruption or discontinuance of
service shall not be deemed an eviction or disturbance of Tenant's use or
possession of the Premises, or any part thereof, nor render Landlord liable to

maintenance shall be performed with reasonable promptness and in a good and
workmanlike manner.

8.       ALTERNATIONS.

         (a)      Alterations to the Premises shall not be made without the
prior consent of Landlord, which shall not be unreasonably withheld. Unless
Landlord permits Tenant to make approved alterations (which permission may be
withheld in Landlord's sole discretion), alterations shall be made by Landlord
and Tenant shall pay Landlord the cost thereof plus 15 percent for Landlord's
overhead and profit within 10 days of Landlord's demand. If Tenant is permitted
to make alterations, the work shall be done in accordance with such
requirements as Landlord may reasonably impose. Any review or approval by
Landlord of plans or specifications with respect to any alteration is solely
for Landlord's benefit, and without any representation or warranty whatsoever
to Tenant with respect to the adequacy, correctness or efficiency thereof. If
required by Landlord, alterations shall be removed by Tenant upon the
termination of the Term and Tenant shall at its expense repair any damage to
the Premises or the Building caused by the removal.

         (b)      Tenant shall indemnify and defend Landlord for, from and
against any and all mechanics' and other liens and encumbrances filed by any
person claiming through or under Tenant and against all costs, expenses, losses
and liabilities (including reasonable attorneys' fees) incurred by Landlord in
connection with any such lien or encumbrance or any action or proceeding
brought thereon. Tenant at its expense shall procure the discharge of record of
all such liens and encumbrances within 20 days after notice thereof.

judgment. All such insurance shall be issued by insurers authorized to do
business in the State, shall name Landlord as an additional insured or shall
contain appropriate endorsements denying Tenant's insurers the right of
subrogation against Landlord. Tenant shall, upon request, furnish Landlord with
certificates evidencing such insurance coverages. If during the Term insurance

insurance premiums within 10 days after Landlord's demand (accompanied by

provided in Section 11). Anything in this Lease to the contrary
notwithstanding, Landlord and Tenant each waive any claims (except claims
arising under Section 11) that either of them may have against the other for
any damage or injury to property caused by the other's negligence, including
the premises and the Building arising from a peril coverable by fire or
extended coverage insurance, whether or not caused by the other, or its agents,
employees or contractors. Neither party shall in any event (except as provided
in Sections 13 and 23) be liable to the other for indirect or consequential
damages for any breach of this Lease. The provisions of this Section shall
survive the termination or expiration of this Lease.

11.      OBSERVANCE OF LAWS.

         Tenant shall at its expense comply with all laws, including the
requirements and regulations of any governmental authority having jurisdiction
(collectively, the Laws), including those which relate to: (a) the
partitioning, equipment operation, alteration, occupancy and use of the
Premises, (b) environmental matters (including the storage, disposal or
generation of hazardous materials), (c) the making of any repairs, replacements
or improvements to the Premises and (d) any business conducted in the Premises.
Except as provided in the preceding sentence, Landlord shall comply with all
Laws which relate to the Building, provided nevertheless, that structural
changes shall be the responsibility of Tenant if



<PAGE>   23

they are changes required by reason of a condition which has been created or
caused by Tenant, or are required by reason of a default by Tenant.

12.      SURRENDER OF THE PREMISES.

         Tenant, on the Termination Date or earlier expiration of the Term,
shall surrender the Premises in as good condition as when Tenant took
possession, except for reasonable wear and tear. Any of Tenant's property
(except money and securities) left on the Premises shall be deemed abandoned
and, at Landlord's option, title shall pass to Landlord under this Lease as by
a bill of sale, or, if Landlord elects to remove all or any part of Tenant's
property, the cost of such removal, including repairing any damage to the
Premises or Building caused by the removal and the cost of storage and sale,
shall be paid by Tenant within 10 days of Landlord's demand.

13.      HOLDING OVER.

         If Tenant retains possession of all or part of the premises after the
Termination Date, Tenant's occupancy shall be as a tenant at sufferance,
terminable at any time by Landlord. Tenant shall pay Landlord rent for such
time as Tenant remains in possession at the monthly rate of 150 percent of the
Base Rent payable hereunder for the month immediately preceding the Termination
Date plus all other Rent required by the terms of this Lease. And, in addition
thereto, shall pay Landlord for all damages including consequential damages)
sustained by reason of Tenant's retention of possession. The provisions of this
Section do not exclude Landlord's rights of reentry or any other right
hereunder.

14.      DAMAGE.

         (a)      If the Building, Land or Premises are damaged by fire or
other casualty and this Lease is not terminated as provided below, Landlord
shall repair the damage at its expense (except for excess costs related to
above-standard leasehold improvements in the Premises which shall be at
Tenant's expense), with reasonable promptness after notice to it of the damage;
provided, however, that Landlord shall not be required to repair or replace any
of Tenant's property or any alteration or improvements made by Tenant. If the
Premises are damaged by fire or other casualty, then to the extent that the
premises are rendered untenantable, the Rent shall equitably abate from the
date of the damage to the date the damage is repaired. If repairs are delayed
in any way by Tenant or Tenant's Representatives, the damage shall be deemed
repaired for purposes of this Section on the date when they would have been
repaired but for such delay.

         (b)      If the Building, Land or Premises are substantially damaged
by fire or other casualty, landlord may terminate this Lease by notice to
Tenant within 90 days after the date of the damage and this Lease shall
terminate upon the 30th day after such notice by which dated Tenant shall
vacate and surrender the Premises to Landlord. The Rent shall be equitably
prorated to the date of termination. The Building, Land or Premises (whether or
not the Premises are damaged) shall be deemed substantially damaged if: (1)
Landlord is required to expend for repairs more than 20 percent of the
replacement value of the Building immediately



<PAGE>   24

prior to the damage, or (2) repair is not possible in accordance, with
landlord's reasonable estimate within 180 days following the date of the
damage.

         (c)      If this Lease has not been terminated and Landlord does not
substantially complete the repair or restoration of the Building, Land or
Premises within 180 days after the date of the casualty, and if such failure
has a material, adverse effect on Tenant's business in the Premises, Tenant may
(provided such failure is not due to any fault of Tenant or Tenant's
Representatives) terminate this Lease by notice to Landlord given within 10
days after the end of the 180-day period. Termination shall be effective 30
days after such notice is given unless Landlord shall substantially complete
the repair or restoration within the 30-day period, in which case Tenant's
notice of termination shall be deemed withdrawn. This Section is intended to
provide the only remedies available to Tenant for damage caused by casualty
and, therefore, to the extent permitted by Law, Tenant waives the provisions of
any Laws which would provide alternative or additional remedies in the event of
such damage.

15.      CONDEMNATION.

         (a)      If the Building, land or Premises are taken for more than 180
days by condemnation or under threat thereof for any public or quasi-public
purpose, this Lease shall terminate as of the date Tenant is required to vacate
the Premises by reason of the taking and the Rent shall be equitably prorated
to such date. If any part of the Building or Land is so taken, this Lease shall
be unaffected by such taking if (A) the cost of restoration will exceed the
award received as a result of the taking, (B) repair is not possible in
accordance with Landlord's reasonable estimate within 180 days following the
date of the taking, or (C) in Landlord's reasonable judgment, it will be unable
to economically operate the Building in light of Landlord's agreements and
obligations regarding the Building, and (2) Tenant may terminate this Lease by
notice to Landlord within 90 days after the date of taking if 20 percent or
more of the premises shall be taken and the remaining area of the Premises
shall not be reasonably sufficient for Tenant to continue operation of its
business. This Lease shall terminate on the 30th day after such notice by which
date Tenant shall vacate and surrender the Premises to Landlord and the Rent
shall be equitably prorated to such date. If this Lease continues in force upon
a temporary taking (180 days or less) or a partial taking, the Base Rent,
Tenant's Proportionate share and other relevant items shall be equitably
adjusted accordingly to the rentable area of the Premises and Building
remaining.

         (b)      In the event of any taking, all of the proceeds of any award
payable by the condemning authority shall be and remain the sole and exclusive
property of Landlord, and Tenant hereby assigns all of its right, title and
interest in and to any award to Landlord. Tenant, however, shall have the
right, to the extent that the same shall not reduce, delay or prejudice
Landlord's award, to claim from the condemning authority, but not from
Landlord, such compensation as may be recoverable by Tenant in its own right
for moving expenses.

16.      ASSIGNMENT AND SUBLETTING.

         (a)      Tenant shall not, either directly or indirectly (including
transfers of interests in Tenant), assign or encumber this Lease or any
interest therein or sublet the Premises or any part



<PAGE>   25

thereof without the prior consent of Landlord in each instance, which consent
shall not be unreasonably withheld; provided, however, in no event may this
Lease be assigned or the Premises sublet to any governmental authority or
agency or to any tenant or occupant of the Building, nor may the rental rate of
any sublease be less than the market rate of such space. The consent by
landlord to an assignment or subletting shall not be construed to relieve
Tenant from obtaining Landlord's consent to any further assignment or
subletting.

         (b)      Tenant shall give Landlord notice of Tenant's intent to
assign this lease or sublet the Premises in whole or in part (including
Tenant's estimate of the date of assignment or sublease will be effective
(Estimated Date) and, in the case of a sublease, the area affected and the
intended period of the sublease) and Landlord shall have the option,
exercisable by delivery to Tenant of notice within 90 days after receipt of
Tenant's notice, to terminate this Lease (in the case of a proposed assignment)
or to terminate or suspend this Lease as to that portion of the Premises which
Tenant seeks to sublet (if Landlord elects to suspend, the Lease with respect
to the sublet area shall be suspended only during the period specified by
Tenant in its notice and the Rent shall be equitably reduced only for such
period). If Landlord fails to give such notice, Landlord shall be deemed to
have rejected its option to terminate or suspend and Tenant may proceed to
attempt to assign or sublet, subject to the requirements of this Section 16,
including Landlord's prior consent. If Landlord exercises its option to
terminate or suspend, Landlord shall be entitled to recover possession of all
or such portion of the Premises as is applicable and Tenant shall vacate the
same on the later of the date which is 60 days after the giving of Landlord's
notice of termination (or suspension) or the Estimated Date, the Rent shall be
adjusted to the date of vacation and thereafter (or for the period of the
suspension) Tenant shall be relieved of all liability for the vacated portion
of the Premises. In the case of a suspension, Landlord shall redeliver
possession of the suspended portion of the Premises to Tenant "as is" at the
expiration thereof.

         (c)      If Landlord gives its consent to any assignment of this lease
or to any sublease, Tenant shall in consideration therefor, pay to Landlord, as
additional rent: (1) in the case of an assignment, an amount equal to all sums
and other consideration paid to Tenant by the assignee for or by reason of such
assignment (including any sums paid for the sale, rental or use of Tenant's
property in excess of the then market value of Tenant's property), less the
reasonable expenses actually paid by Tenant in connection with the assignment;
and (2) in the case of a sublease, any rents, additional charges or other
consideration payable under the sublease to Tenant by the subtentant (including
any sums paid for the sale, rental or use of Tenant's property in excess of the
then market value of Tenant's property) which are in excess of the Rent during
the term of the sublease in respect of the subleased space, less the reasonable
expenses actually paid by Tenant in connection with the subletting. The sums
payable hereunder shall be paid to Landlord as an when payable by the assignee
or subtenant to Tenant.

         (d)      No assignment or subletting shall affect the continuing
primary liability of Tenant (which, following an assignment, shall be joint and
several with the assignee), and Tenant shall not be released from performing
any of the terms, covenants and conditions of this Lease.



<PAGE>   26

17.      SUBORDINATION.

         This Lease and all rights of Tenant hereunder shall be, at the option
and designation of Landlord, subordinate or superior to any lease of the
Building or Land (an Underlying Lease) and to any mortgage or deed of trust (a
Mortgage) which may now or hereafter affect the Building or Land. If Landlord
designates this Lease as subordinate or superior to any Underlying Lease or
Mortgage, this Section shall be self-operative and no further agreements of
subordination or superiority shall be required but, in confirmation of such
subordination or superiority, Tenant shall promptly execute, acknowledge and
deliver any agreement that Landlord, the lessor under any Underlying Lease
(Lessor) or the holder of any Mortgage (Mortgagee) or any of their respective
assigns or successors in interest may reasonably request to evidence such
subordination or superiority. If any Lessor or Mortgagee (or any purchaser at a
foreclosure sale) succeeds to the rights of Landlord under this Lease, whether
through possession or foreclosure action or delivery of a new lease or deed (a
Successor Landlord), Tenant shall, upon request, attorn to and recognize the
Successor Landlord as Tenant's landlord under this Lease and shall promptly
execute and deliver any agreement that the Successor Landlord may reasonably
request to evidence such attornment. If a Lessor, Mortgagee or Successor
Landlord requires that an agreement of subordination, superiority or attornment
be executed by Tenant in accordance with this Section, Tenant's failure to do
so within 15 days after Landlord's request shall be deemed an event of default
under this Lease.

18.      ESTOPPEL CERTIFICATE.

         Tenant shall from time to time deliver to Landlord a statement in
writing certifying the status of this Lease and any options contained herein,
the performance hereunder of Landlord and Tenant and such other matters as
Landlord shall reasonably request. Tenant's failure to do so within 15 days
after Landlord's request shall be deemed an event of default under this Lease.

19.      TRANSFER OF LANDLORD'S INTEREST.

         The term "Landlord" as used in this Lease shall be limited to mean and
include only the owners of Landlord's interest in this Lease at the time in
question. Upon any transfer of such interest, Landlord herein named (and in
case of any subsequent transfer, the then transferor) shall thereafter be
relieved of all liability for the performance of any obligations on the part of
Landlord contained in this Lease.

20.      QUIET ENJOYMENT.

         Tenant, upon paying the Rent and performing all of the terms,
covenants and conditions on its part to be performed, shall peaceably and
quietly enjoy the Premises subject, nevertheless, to the terms of this Lease.

21.      RIGHTS RESERVED TO THE LANDLORD.

         Landlord reserves the right: (a) to name the Building and Office Park,
to change the name or street address of the Building and Office Park, and to
install and maintain all signs in the Office Park (including the exterior and
interior of the Building); (b) on reasonable prior notice to Tenant, to exhibit
the Premises to any prospective purchaser or mortgagee of the



<PAGE>   27

Building or Land and to others having an interest therein at any time during
the Term, and to prospective tenants during the last 12 months of the Term; (c)
to enter the Premises to make necessary inspections repairs and adjustments or
otherwise to comply with the terms of this Lease; and (d) to relocate, alter,
improve, reduce or add to the configuration of and the various facilities and
improvements within the Building, the Land and the Office Park, provided that
the change shall not materially restrict Tenant's access to or use of the
Premises.

22.      DEFAULT.

         The following shall be deemed event of default under this Lease: (a)
Tenant's failure to make any payment of Rent when it is due and payable
(provided that Tenant shall be entitled to 10 days notice of nonpayment during
which Tenant may cure the default, unless on 2 prior occasions within the same
12-month period there has been a default in the payment of Rent which has been
cured after notice has been given by Landlord, in which case no such notice
need be given for the remainder of the 12-month period and no such default in
the payment of Rent shall be curable, except as may be required by applicable
Laws), (b) any matter defined as an event of default in this Lease, (c)
Tenant's failure to cure a default in the performance of any other covenant or
obligation of Tenant under this Lease within a period of 30 days after notice
from Landlord specifying the default (or if the specified default is not
capable of cure within the 30-day period, if Tenant fails immediately after
notice from Landlord to commence to cure the default and diligently to pursue
completion of the cure during and after the 30-day period), and (d) Tenant's
failure to occupy substantially all of the Premises within 30 days after
Landlord delivers the Premises to Tenant in the condition required by this
Lease or Tenant's vacation of more than 50 percent of the Premises for more
than 30 days except in accordance with an approved assignment or sublease.

23.      REMEDIES.

         (a)      If any event of default occurs, Landlord may, without
prejudice to Landlord's other rights hereunder and in addition to all other
rights and remedies which Landlord may have under the Laws:

                  (1)      cure such default and any reasonable costs and
expenses incurred by Landlord therefor shall be deemed additional rent payable
on demand; or

                  (2)      with or without terminating this Lease, reenter the
Premises and take possession thereof from Tenant by legal proceedings or
otherwise. If Landlord takes possession of the Premises and if the remedy
provided in this Section 23(a)(2) is permitted under the Laws after termination
of a lease, this Lease shall terminate, otherwise it shall remain in full force
and effect. Thereafter Landlord may recover from Tenant: (A) the worth at the
time of award of the unpaid Rent which had been earned at the time of such
termination; (B) the worth at the time of the award of the amount by which the
unpaid Rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; (C) the worth at the time of award of the amount by which
the unpaid Rent for the balance of the Term after the time of award exceeds the
amount of such rental loss that Tenant proves could be reasonably avoided; and
(D) any other amount necessary



<PAGE>   28

to compensate Landlord for all the detriment proximately caused by Tenant's
failure to perform its obligations under this Lease or which in the ordinary
course of things would be likely to result therefrom. The "worth at the time of
the award" of the amounts referred to in Subdivisions (A) and (B) is computed
by allowing interest at the lesser of 12 percent per annum or the maximum rate
which Landlord may lawfully charge Tenant. The worth at the time of award of
the amount referred to in Subdivision (C) is computed by discounting such
amount at the discount rate of the nearest Federal Reserve Bank at the time of
award plus one percent. Efforts by Landlord to mitigate the damages caused by
Tenant's breach of this Lease shall not constitute a waiver of Landlord's right
to recover damages under this or any other Section. Nothing in this Section
shall affect Landlord's rights to indemnification under any of the other
provisions of this Lease; or

         (3)      continue this Lease in full force and effect for so long as
Landlord does not exercise Landlord's right to terminate this Lease and
Landlord may enforce all Landlord's rights and remedies under this Lease,
including the right to recover the Rent as it becomes due. For purposes of this
Section, the following acts by Landlord shall not constitute a termination of
Tenant's right to possession of the Premises or a termination of the Lease: (A)
Acts of maintenance or preservation or efforts to relet the Premises; or (B)
the appointment of a receiver upon the initiative of Landlord to protect
Landlord's interest under this Lease.

                  (b)      Landlord shall use reasonable efforts to mitigate
its damages in the event of Tenant's default. If Tenant has vacated the
Premises, Landlord shall be deemed to have satisfied its obligation under this
provision if it markets the Premises in the same manner as it markets other
available space in the Building or the Office Park (if applicable). Landlord,
however, shall not be required to prefer the Premises over such other available
space.

                  (c)      Except as provided in Section 23(a)(2), no reentry
or taking possession of the Premises by Landlord shall be construed as an
election to terminate this Lease, unless notice to such effect is given by
Landlord to Tenant. If Landlord does reenter or take possession without
terminating this Lease, Landlord may, at any time thereafter, terminate this
Lease by giving notice to Tenant. All of the remedies given to Landlord in this
Lease upon any event of default are in addition to all other rights or remedies
to which Landlord may be entitled under the Laws, including, if available, the
right to restrict Tenant's access to the Premises; all such remedies shall be
deemed cumulative and the election of one shall not be deemed a waiver of any
other or further rights or remedies. Unless otherwise expressly provided
herein, Tenant's obligation to pay all the Rent due through the Termination
Date shall survive any termination or expiration of this Lease.

24.      SECURITY DEPOSIT.

         Tenant has deposited with Landlord the Security Deposit as security
for the faithful performance of every provision of this Lease to be performed
by Tenant. If Tenant defaults with respect to any provision of this Lease,
including payment of the Rent, Landlord may apply all or any part of the
Security Deposit for the payment of any Rent or to compensate Landlord for any
other loss, cost or liability which Landlord may incur by reason of Tenant's
default. If



<PAGE>   29

any portion of the Security Deposit is so applied, Tenant shall, within 10 days
after notice thereof, deposit cash with Landlord in an amount sufficient to
restore the Security Deposit to its original amount and Tenant's failure to do
so shall be deemed an event of default under this Lease. The Security Deposit
or any balance thereof shall be returned to Tenant without interest (or, at
Landlord's option, to the last transferee of Tenant's interest hereunder) at
the expiration of the Term and upon Tenant's vacation of the Premises in
accordance with the terms of this Lease. If the Building is sold, the Security
Deposit may be transferred to the new owner and Landlord shall be discharged
from further liability with respect thereto.

25.      BANKRUPTCY.

         If Tenant files a voluntary petition pursuant to the Bankruptcy Code
(including any successor code) or takes the benefit of any insolvency act or is
dissolved, or if an involuntary petition is filed against Tenant pursuant to
the Bankruptcy Code and the petition is not dismissed within 60 days after the
filing, if a receiver is appointed for Tenant's business or assets and the
appointment of the receiver is not vacated within 60 days after the
appointment, or if Tenant shall make an assignment for the benefit of
creditors, then Landlord shall have all of the rights provided in Section 23
for nonpayment of the Rent to the extent permitted by the Laws.

26.      FORCE MAJEURE.

         Landlord shall be excused for the period of any delay in the
performance of any obligation hereunder when prevented from so doing by causes
beyond its control, including labor disputes, civil commotion, hostilities,
sabotage, governmental regulations or controls, fire or other casualty,
inability to obtain any material, financing or services, and acts of God.
Tenant shall similarly be excused for delay in the performance of any
obligation hereunder, provided that nothing contained in this Section shall be
deemed to excuse or permit any delay in the payment of Rent or any delay in the
cure of any default which may be cured by the payment of money.

27.      LIMITATION OF LIABILITY

         If Landlord becomes obligated to pay Tenant a money judgment arising
out of any failure by Landlord to perform any of its obligations under this
Lease, Tenant shall be limited for the satisfaction of the money judgment
solely to Landlord's interest in the Building and Land and no other property or
assets of Landlord or the individual partners, directors, officers, or
shareholders of Landlord shall be subject to levy, execution or other
enforcement procedure whatsoever for the satisfaction of the money judgment.

28.      PARKING.

         (a)      Landlord hereby permits Tenant the right to use the Parking
Spaces. Landlord, at its sole election, may designate the types and locations
of the Parking Spaces and Landlord shall have the right, at Landlord's sole
election, to change the types and locations from time to



<PAGE>   30

time; provided, however, such designation shall not reduce the number of
Parking Spaces permitted Tenant by this Lease. If Landlord institutes an
automobile identification procedure, Tenant shall cooperate with Landlord's
reasonable requirements therefor.

         (b)      Commencing on the Commencement Date, Tenant shall pay
Landlord the Parking Fee, if any, as additional rent, payable monthly in
advance with Monthly Installments of Base Rent. Thereafter, and throughout the
Term, the Parking Fee may be changed from time to time based on Landlord's
standard parking rates (plus any amounts assessed or required to be paid to any
governmental authority on account of the parking of motor vehicles) for each
type of parking space provided to Tenant.

29.      RELOCATION.

         Landlord may elect by notice to Tenant to substitute for the Premises
other office space in the Building or the Office Park (the Substitute Premises)
designated by Landlord and reasonably satisfactory to Tenant, provided that the
Substitute Premises shall contain at least the same usable area as the Premises
and have a configuration substantially similar to the Premises. Landlord shall,
at Landlord's expense, be responsible for: (a) completion of all improvements
to the Substitute Premises to Tenant's reasonable satisfaction, (b) moving all
of Tenant's property, (c) prompt reimbursement of all Tenant's reasonable
out-of-pocket expenses incurred by Tenant in connection with Tenant's move from
the Premises to the Substitute Premises provided such costs are approved by
Landlord in advance, which approval shall not be unreasonably withheld. Tenant
shall vacate and surrender the Premises and shall occupy the Substitute
Premises within 15 days after Landlord has substantially completed the work to
be performed by Landlord in the Substitute Premises pursuant to this Section.
Tenant shall pay the same Rent with respect to the Substitute Premises as was
payable with respect to the Premises, notwithstanding that the usable area of
the Substitute Premises may be greater than that of the Premises. This Lease
shall remain in full force and effect, and the Substitute Premises shall
thereafter be deemed to be the Premises.

30.      BROKERAGE FEES.

         Tenant warrants and represents that it has not dealt with any other
party (including a broker or other agent) in connection with this Lease except
Broker. Tenant shall indemnify and defend Landlord for, from and against any
claims, expenses, liabilities and losses (including reasonable attorneys' fees)
resulting from any compensation, commissions or charges claimed by or owing to
any other party in connection with this Lease by reason of any act of Tenant.

31.      NOTICES.

         All notices, demands, consents, approvals, elections or other
communications permitted or required to be given hereunder (a notice or
notices) shall be in writing and shall be deemed given on the date of actual
receipt by the party to which it is directed, notwithstanding any further
direction to the attention of any individual or department; provided that if
notices are required by this Lease to be sent to the attention of any
individual or department, the notice



<PAGE>   31

shall be effective only if the envelope or wrapper in which it is sent is so
addressed. Notices shall be addressed as follows: (a) if to Landlord, to the
Landlord's Mailing Address and to the Building Manager, and (b) if to Tenant,
to the Tenant's Mailing Address. Any address or name specified above may be
changed by a notice given to the addressee by the other party in accordance
with this Section. The inability to deliver a notice because of a changed
address for which no prior notice was given or rejection or other refusal to
accept any notice shall be deemed to be the receipt of the notice as of the
date of such inability to deliver or rejection or refusal to accept.

32.      MISCELLANEOUS

         (a)      This Lease shall be deemed to have been made in and shall be
construed in accordance with the Laws of the State. This Lease has been
executed in several counterparts, all of which constitute one and the same
instrument. The captions appearing within the body of this Lease have been
inserted as a matter of convenience and for reference only and in no way
define, limit or enlarge the scope or meaning of this Lease or of any provision
hereof. This Lease sets forth all the agreements and understandings between
Landlord and Tenant and there are no agreements or understandings, either oral
or written, between them other than as are herein set forth. No amendment or
change to this Lease shall be binding upon Landlord or Tenant unless reduced to
writing and signed by both of them.

         (b)      As used in this Lease, any list of one or more items preceded
by the word "including" shall not be deemed limited to the stated items but
shall be deemed without limitation.

         (c)      If any provision of this Lease is or becomes illegal or
unenforceable because of current or future Laws effective during the Term, the
intention of the parties hereto is that the remaining parts of this Lease shall
not be affected thereby.

         (d)      The failure of either party to exercise any remedy or
election shall not be construed as a waiver for the future of such remedy or
election, but the same shall remain in full force and effect. The receipt by
Landlord of full or partial Rent with knowledge of a breach of this Lease shall
not be deemed a waiver of such breach. No payment of a lesser amount than the
Rent due Landlord shall be deemed to be other than on account of the Rent and
Landlord may accept payment without prejudice to Landlord's right to recover
the balance of such Rent or pursue any other remedy provided in this Lease,
notwithstanding any endorsement or statement accompanying the payment to the
contrary.

         (e)      In any proceeding which Landlord or Tenant may prosecute to
enforce its rights hereunder, the unsuccessful party shall pay all costs
incurred by the prevailing party (as such parties are hereafter defined),
including reasonable attorneys' fees. Prior to commencing any proceeding the
parties shall each submit to the other a final offer of settlement. The failure
of a party (as plaintiff) to submit a settlement offer shall be deemed a demand
for all the relief requested in its complaint and the failure of a party (as
defendant) to submit a responding settlement offer within 10 days after its
receipt of a settlement offer shall be deemed a rejection



<PAGE>   32

of any relief for the benefit of the plaintiff. If the forum in which the
proceeding is heard renders a judgment at least as favorable to a party as its
settlement offer, such party shall be deemed the prevailing party for purposes
of this Section.

         (f)      If any proceeding is commenced between the parties to settle
any dispute, neither Landlord nor Tenant shall permit its attorneys to engage
in any dilatory conduct. At the conclusion thereof and regardless of the
outcome, the attorneys appearing of record for both parties shall be required
to submit themselves to the judge or other adjudicator for a review of their
conduct during the proceeding. If any such attorney is found to have engaged in
dilatory conduct, that attorney shall agree to perform up to 10 hours of
community or pro bono service, as directed by the judge or adjudicator.

         (g)      If Landlord commences any summary proceeding (or equivalent)
or an action for nonpayment of Rent, Tenant shall not interpose any
non-mandatory counterclaim of any nature or description in the proceeding or
action, provided that this prohibition shall not prevent Tenant from raising
any appropriate defense in such proceeding or action and any such underlying
claim shall be preserved for any subsequent action commenced by Tenant against
Landlord. Tenant and Landlord both waive a trial by jury of any or all issues
arising in any action or proceeding between the parties under this Lease.

         (h)      All the terms and provisions of this Lease shall be binding
