                           CERTIFICATE OF DESIGNATION
                                       OF
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                         (PURSUANT TO SECTION 151 OF THE
                        DELAWARE GENERAL CORPORATION LAW)

         AURORA BIOSCIENCES CORPORATION, a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Company"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Company as required by Section 151 of the General
Corporation Law at a meeting duly called and held on March 30, 2001:

                           RESOLVED, that pursuant to the authority granted to
                  and vested in the Board of Directors of the Company in
                  accordance with the provisions of its Amended and Restated
                  Certificate of Incorporation, the Board of Directors hereby
                  creates a series of Preferred Stock, par value $.001 per
                  share, of the Company and hereby states the designation and
                  number of shares, and fixes the relative designations and the
                  powers, preferences and rights, and the qualifications,
                  limitations and restrictions thereof (in addition to the
                  provisions set forth in the Certificate of Incorporation of
                  the Company, which are applicable to the Preferred Stock of
                  all classes and series), as follows:

Series A Junior Participating Preferred Stock:

         SECTION 1. DESIGNATION AND AMOUNT. One million five hundred thousand
(1,500,000) shares of Preferred Stock, $.001 par value, are designated "Series A
Junior Participating Preferred Stock" with the designations and the powers,
preferences and rights, and the qualifications, limitations and restrictions
specified herein (the "Junior Preferred Stock"). Such number of shares may be
increased or decreased by resolution of the Board of Directors; provided, that
no decrease shall reduce the number of shares of Junior Preferred Stock to a
number less than the number of shares then outstanding plus the number of shares
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Company convertible into Junior Preferred Stock.

         SECTION 2. DIVIDENDS AND DISTRIBUTIONS.

                  (A) Subject to the rights of the holders of any shares of any
series of Preferred Stock (or any similar stock) ranking prior and superior to
the Junior Preferred Stock with respect to dividends, the holders of shares of
Junior Preferred Stock, in preference to the holders of

                                       1
<PAGE>   2

Common Stock, par value $.001 per share (the "Common Stock"), of the Company,
and of any other junior stock, shall be entitled to receive, when, as and if
declared by the Board of Directors out of funds legally available for the
purpose, quarterly dividends payable in cash on the first day of April, July,
October and January in each year (each such date being referred to herein as a
"Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend
Payment Date after the first issuance of a share or fraction of a share of
Junior Preferred Stock, in an amount per share (rounded to the nearest cent)
equal to the greater of (a) $l.00 or (b) subject to the provision for adjustment
hereinafter set forth, 100 times the aggregate per share amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash dividends or other distributions, other than a dividend payable in
shares of Common Stock or a subdivision of the outstanding shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Junior Preferred Stock. In the event the Company shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the amount to which holders of
shares of Junior Preferred Stock were entitled immediately prior to such event
under clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

         (B) The Company shall declare a dividend or distribution on the Junior
Preferred Stock as provided in paragraph (A) of this Section immediately after
it declares a dividend or distribution on the Common Stock (other than a
dividend payable in shares of Common Stock); provided, that in the event no
dividend or distribution shall have been declared on the Common Stock during the
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $1.00 per share on the Junior
Preferred Stock shall nevertheless be payable on such subsequent Quarterly
Dividend Payment Date.

         (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Junior Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares, unless the date of issue of such
shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Junior Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative from such Quarterly Dividend
Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends
paid on the shares of Junior Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Junior Preferred

                                       2
<PAGE>   3

Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be not more than 60 days prior to the date
fixed for the payment thereof.

         SECTION 3. VOTING RIGHTS. The holders of shares of Junior Preferred
Stock shall have the following voting rights:

                  (A) Subject to the provision for adjustment hereinafter set
forth, each share of Junior Preferred Stock shall entitle the holder thereof to
100 votes on all matters submitted to a vote of the stockholders of the Company.
In the event the Company shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares of Junior
Preferred Stock were entitled immediately prior to such event shall be adjusted
by multiplying such number by a fraction, the numerator of which is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  (B) Except as otherwise provided herein, in any other
Certificate of Designation creating a series of Preferred Stock or any similar
stock, or by law, the holders of shares of Junior Preferred Stock and the
holders of shares of Common Stock and any other capital stock of the Company
having general voting rights shall vote together as one class on all matters
submitted to a vote of stockholders of the Company.

                  (C) Except as set forth herein, or as otherwise provided by
law, holders of Junior Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for taking any corporate
action.

         SECTION 4. CERTAIN RESTRICTIONS.

                  (A) Whenever quarterly dividends or other dividends or
distributions payable on the Junior Preferred Stock as provided in Section 2 are
in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Junior Preferred Stock
outstanding shall have been paid in full, the Company shall not:

                           (i) declare or pay dividends, or make any other
distributions, on any shares of stock ranking junior (either as to dividends or
upon liquidation, dissolution or winding up) to the Junior Preferred Stock;

                           (ii) declare or pay dividends, or make any other
distributions, on any shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Junior
Preferred Stock, except dividends paid ratably on the Junior Preferred Stock and
all such parity stock on which dividends are payable or in arrears in proportion
to the total amounts to which the holders of all such shares are then entitled;

                                       3
<PAGE>   4

                           (iii) redeem or purchase or otherwise acquire for
consideration shares of any stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Junior Preferred Stock, provided
that the Company may at any time redeem, purchase or otherwise acquire shares of
any such junior stock in exchange for shares of any stock of the Company ranking
junior (either as to dividends or upon dissolution, liquidation or winding up)
to the Junior Preferred Stock; or

                           (iv) redeem or purchase or otherwise acquire for
consideration any shares of Junior Preferred Stock, or any shares of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or
winding up) with the Junior Preferred Stock, except in accordance with a
purchase offer made in writing or by publication (as determined by the Board of
Directors) to all holders of such shares upon such terms as the Board of
Directors, after consideration of the respective annual dividend rates and other
relative rights and preferences of the respective series and classes, shall
determine in good faith will result in fair and equitable treatment among the
respective series or classes.

                  (B) The Company shall not permit any subsidiary of the Company
to purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

         SECTION 5. REACQUIRED SHARES. Any shares of Junior Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of Preferred
Stock and may be reissued as part of a new series of Preferred Stock subject to
the conditions and restrictions on issuance set forth herein, in the Amended and
Restated Certificate of Incorporation, or in any other Certificate of
Designation creating a series of Preferred Stock or any similar stock or as
otherwise required by law.

         SECTION 6. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Junior
Preferred Stock unless, prior thereto, the holders of shares of Junior Preferred
Stock shall have received $100 per share, plus an amount equal to accrued and
unpaid dividends and distributions thereon, whether or not declared, to the date
of such payment, provided that the holders of shares of Junior Preferred Stock
shall be entitled to receive an aggregate amount per share, subject to the
provision for adjustment hereinafter set forth, equal to 100 times the aggregate
amount to be distributed per share to holders of shares of Common Stock, or (2)
to the holders of shares of stock ranking on a parity (either as to dividends or
upon liquidation, dissolution or winding up) with the Junior Preferred Stock,
except distributions made ratably on the Junior Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled upon such liquidation, dissolution or winding up. In the
event the Company shall at any time declare or pay any dividend on the Common
Stock payable in shares of Common Stock, or effect a subdivision or combination
or consolidation of the outstanding shares of Common Stock (by reclassification
or otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of Junior

                                       4
<PAGE>   5

Preferred Stock were entitled immediately prior to such event under the proviso
in clause (1) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

         SECTION 7. CONSOLIDATION, MERGER, ETC. In case the Company shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Junior Preferred Stock shall at the same time be similarly exchanged or changed
into an amount per share, subject to the provision for adjustment hereinafter
set forth, equal to 100 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is changed or exchanged. In the event the
Company shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
amount set forth in the preceding sentence with respect to the exchange or
change of shares of Junior Preferred Stock shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

         SECTION 8. NO REDEMPTION. The shares of Junior Preferred Stock shall
not be redeemable.

         SECTION 9. RANK. The Junior Preferred Stock shall rank, with respect to
the payment of dividends and the distribution of assets, junior to all series of
any other class of the Company's Preferred Stock.

         SECTION 10. AMENDMENT. The Amended and Restated Certificate of
Incorporation of the Company shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Junior Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of at least two-thirds of the outstanding shares of Junior
Preferred Stock, voting together as a single class.

and are hereby assented to by the Lessee:

         FIRST: The Lessee shall not assign this Lease, nor sub-let the

the same, or any part thereof, to be used for any other purpose than as above
stipulated, nor make any alterations therein, and all additions thereto, without

will be approximately 5,000 square feet ("Sub-Let") which Sub-Let shall be
subject to the Lessor's prior written consent, which consent shall not be
unreasonably withheld or delayed.

                                       1

<PAGE>

         SECOND: All personal property placed or moved in the Premises above
described shall be at the risk of the Lessee or owner thereof, and Lessor shall
not be liable for any damage to said personal property, or to the Lessee arising
from the bursting or leaking of water pipes, or from any act of negligence of
any co-tenant or occupants of the Building or of any other person whomsoever,
except for Lessor's willful misconduct or gross negligence.

         THIRD: That the Lessee shall promptly execute and comply with all
statutes, ordinances, rules, orders, regulations and requirements of the
Federal, State and City Government and of any and all their Departments and
Bureaus applicable to said Premises, for the correction, prevention, and
abatement of nuisances or other grievances, in, upon, or connected with said
Premises during said term.

         FOURTH: In the event the Premises shall be destroyed or so damaged or
injured by fire or other casualty during the life of this Lease, whereby the
same shall be rendered untenantable, then the Lessor shall have the right to
render said Premises tenantable by repairs within 180 days therefrom. If said
Premises are not rendered tenantable within said time, it shall be optional with
either party hereto to cancel this Lease, and in the event of such cancellation
the rent shall be paid only to the date of such fire or casualty. The
cancellation herein mentioned shall be evidenced in writing.

         FIFTH: The prompt payment of the rent for said Premises upon the dates
named, and the faithful observance of the rules and regulations printed upon
this Lease, and which are hereby made a part of this covenant, are the
conditions upon which this Lease is made and accepted and any failure on the
part of the Lessee to comply with the terms of said Lease, or any of said rules,
shall at the option of the Lessor, be deemed a default of this Lease.

         SIXTH: If the Lessee shall be in default under this Lease or shall
abandon or vacate said Premises before the end of the term of this Lease (and
Lessee shall fail to pay rent or maintain the Premises as required hereunder),
or shall suffer the rent to be in arrears, the Lessor may, at his option,
forthwith cancel this Lease or he may enter said Premises as the agent of the
Lessee, by force or otherwise (all in accordance with local law), and relet the
Premises with or without any furniture that may be therein, as the agent of the
Lessee, at such price and upon such terms and for such duration of time as the
Lessor may determine, and receive the rent therefor, applying the same to the
payment of the rent due by these presents, and if the full rental herein
provided shall not be realized by Lessor over and above the expenses to Lessor
in such re-letting, the said Lessee shall pay any deficiency, and if more than
the full rental is realized Lessor will pay over to said Lessee the excess of
demand. In the alternative, Lessor may elect to declare the entire rent for the
balance of the Lease Term, or any part thereof, due and payable forthwith, and
to bring an action for the recovery thereof.

         SEVENTH: Lessee agrees to pay the cost of collection and reasonable
attorney's fees on any part of said rental that may be collected by suit or by
attorney, after the same is past due.

         EIGHTH: The Lessee agrees that it will pay all charges for rent, gas,
electricity or other illumination used on said Premises, and should said charges
for rent or light herein provided for at any time remain due and unpaid for the
space of five days after the same shall have become due, the Lessor may at its
option consider the said Lessee tenant at sufferance and immediately re-enter
upon said Premises and the entire rent for the rental period then next ensuing
shall at once be due and payable and may forthwith be collected by distress or
otherwise. In addition, it shall be considered a default of this Lease in the
event a lien is placed against the Building or premises as the result of the
work performed by Lessee or Lessee's contractors, subcontractors or agents and
such lien is not released within thirty (30) days of Lessee receiving notice of
such lien. Lessor represents that the electric utility for the Premises is
separately metered and Lessee may connect same in the name of the Lessee.

         NINTH: The said Lessee hereby pledges and assigns to the Lessor all the
furniture, fixtures, goods, and chattels of said Lessee, which shall or may be
brought or put on said Premises as security for the payment of the rent herein
reserved, and the Lessee agrees that the said lien may be enforced by distress
foreclosure or otherwise at the election of the said Lessor, and does hereby
agree to pay reasonable attorney's fees not to exceed ten percent of the amount
so collected or found to be due, together with all costs and charges therefore
incurred or paid by Lessor.

         TENTH:  [INTENTIONALLY DELETED]

         ELEVENTH: The Lessor, or any of its agents, shall have the right to
enter said Premises during all reasonable business hours, to examine the same to
make such repairs, additions or alterations as may be deemed necessary for the
safety, comfort, or preservation thereof, or of said Building, or to exhibit
said Premises, and to put or keep upon the doors or windows thereof a notice
"FOR RENT" at any time within thirty (30) days before the expiration of this
Lease; provided that Lessor's entry shall not unreasonably interfere with the
business of Lessee. The right of entry shall likewise exist for the purpose of
removing placards, signs, fixtures, alterations, or additions, which do not
conform to this Lease, or to the rules and regulations of the Building.

         TWELFTH: Lessee hereby accepts the Premises in the condition they are
in at date of execution of this Lease and Lessor shall deliver the Premises to
Lessee in the same condition at the commencement of the term of this Lease.
Notwithstanding the foregoing, Lessee acknowledges that the out-going tenant
shall be removing its personal property from the Premises (which may include but

term of this Lease. Lessee agrees to maintain said Premises in the same
condition, order and repair as they are at the commencement of said term,
excepting only reasonable wear and tear arising from the use thereof under this
Lease, and to make good to said Lessor immediately upon demand, any damage to
water apparatus, or electric lights, or any fixtures, appliances or
appurtenances of said Premises, or of the Building, caused by any act or neglect

Lessor, to comply with the terms of this Lease.

         NINETEENTH: The rights of the Lessor under the foregoing shall be
cumulative, and failure on the part of the Lessor to exercise promptly any
rights given hereunder shall not operate to forfeit any of the said rights.

         TWENTIETH: It is further understood and agreed between the parties
hereto that any charges against the Lessee by the Lessor for services or for
work done on the Premises by order of the Lessee or otherwise accruing under

employees. Lessee agrees to obtain liability insurance containing a single limit
of not less than $500,000.00 for both property (including but not limited to
fire hazard) and bodily injury, at its own cost. Lessee consents to provide
Lessor with a Certificate of Insurance, as above described, naming Lessor as

commission, fee or other sum which is now or in the future may be due and
payable with regard to leasing, acquisition or other such matters related to the
Demised Premises. Said fee shall be paid by Lessor. Lessor represents and
warrants that no broker has represented Lessor or that Lessor will be
responsible for any commission by any broker claiming to represent Lessor.
Lessor and Lessee each agree to indemnify and hold each other harmless from any
and all liability for the payment of any other such commissions, fees and other
sums.

         TWENTY-FIFTH: Lessor agrees to provide water and sewer service to the
Building and Premises, maintain the roof, landscaping, irrigation system, the
exterior of the Building, the adjacent lake bank, lighting, loading areas,
parking areas, sidewalks and driveways, and to keep the common areas reasonably

Lessee's Proportionate Share of such costs (which costs include a management fee
that shall not exceed five percent (5%) of rent collected from all of the
lessees of the Building (the "Management Fee"). "Lessee's Proportionate Share"
shall be the fraction or ratio of the floor area of the Lessee's Premises
divided by the total floor area of the Building. (18,509 square feet/173,085
square feet = 10.43%). Lessor represents and warrants to Lessee that Lessee's
Proportionate Share of 10.43% is accurate. Notwithstanding the foregoing, the
Lessee's Proportionate Share shall not include any of the Exclusions to Lessee's
Proportionate Share described in Exhibit E attached hereto.

not to exceed the full replacement cost of the improvements constituting the
Building from time to time. Lessee agrees to pay as additional rent, without
relief from valuation or appraisement laws, Lessee's Proportionate Share of any
such taxes, of any premiums payable in respect of such insurance coverage, and
of any

                                       3

<PAGE>

premiums payable in respect of public liability insurance and rental insurance
maintained by or for the Lessor in respect of the land and the Building. Lessor
shall diligently challenge any Taxes each year when appropriate and any rebates
or refunds ("Refunds"), less the reasonable cost of Lessor's challenge, shall
operate to reduce Lessee's Proportionate Share. In the event that Taxes are
challenged for a year when this Lease was in effect and included in Lessee's
Proportionate Share and a Refund is obtained in a subsequent year, then: (i) if
this Lease is still in effect Lessee's Proportionate Share of such Refund shall
operate to reduce Lessee's Proportionate Share in the year in which received;
and, (ii) if this Lease is not still in effect, Lessee's Proportionate Share of
such Refund shall be paid by Lessor to Lessee upon Lessor's receipt of such
Refund.

certain Declaration of Protective Covenants and Restrictions for Miramar Park of
Commerce. Under the Declaration, Sunbeam Properties, Inc. currently enforces the
Declaration and operates and maintains the Common Area referred to therein. The
Lessee agrees to pay on behalf of Lessor, Lessee's Proportionate Share of any
and all maintenance or other assessments imposed by Sunbeam Properties, Inc. (or
its successor) on the Lessor as owner of the Building as provided in the
Declaration. Based on the current cap under the Declaration, Lessees'
Proportionate Share of the assessments shall not exceed $3,600.00 per year.

         TWENTY-EIGHTH: (a) Lessee shall pay $3,053.99 per month plus State
Sales Tax as an estimate of Lessee's Proportionate Share of the expenses
described in Paragraphs 25, 26 AND 27. Said payment is in addition to all other
sums to be paid by Lessee including but not limited to rent. On an annual basis,
Lessor shall notify Lessee what the actual expenses were over the previous
calendar year and within ten (10) days of such notice, Lessee shall pay (or
receive a reimbursement) for the difference, if any, plus State Sales Tax,
between what Lessee paid as an estimate and the actual expenses. Lessee's share
for a partial calendar year at the beginning or end of the term of this Lease
shall be prorated on a per diem basis. In the event that Lessor adjusts its
estimate of the expenses described in Paragraphs 25, 26 and 27 to more
accurately reflect the actual expenses incurred, Lessee's monthly estimated
payment of its Proportionate Share of such expenses shall be appropriately
adjusted.

                              (b)  Notwithstanding anything to the contrary
contained hereinabove, Lessee's Proportionate Share of Expenses described in
Paragraphs 25 and 27 shall not unreasonably exceed what is typical for similar
quality buildings located in first class business parks in Southwest Broward
County.

                              (c) Lessee reserves the right to inspect and audit
Lessor's records with respect to the Lessee's Proportionate Share and to set
forth objections thereof. Lessor shall keep or cause to be kept books and
records showing Lessee's Proportionate Share for each calendar year in
accordance with generally accepted accounting principles consistently applied.
If such inspection and audit reveals overstated charges of the Lessee's
Proportionate Share, Lessor shall remit the overstated amount to Lessee within
thirty (30) days of demand therefor. In addition, if such overstated amount
equals or exceeds five percent (5%) of the Lessee's Proportionate Share for that
calendar year, Lessor shall also pay the reasonable costs of Lessee's inspection
and audit to Lessee with such payment.

         TWENTY-NINTH: (a) If the whole or any substantial part of the Premises
should be taken for any public or quasi-public use under governmental law,
ordinance or regulation, or by right of eminent domain, or by private purchase
in lieu thereof after a condemnation action has been actually commenced, and the
taking would prevent or materially interfere with the use of the Premises for
the purpose of which they are then being used, this Lease shall terminate and
the rent shall be abated during the unexpired portion of this Lease, effective
when the physical taking shall occur.

                       (b) If part of the Premises shall be taken for any public
or quasi-public use under any governmental law, ordinance or regulation, or by
right of eminent domain, or by private purchase in lieu thereof after a
condemnation action has been actually commenced, and this Lease is not
terminated as provided in the Subparagraph above, this Lease shall not terminate
but the rent payable hereunder during the unexpired portion of this Lease shall
be reduced to such extent as may be fair and reasonable under all of the
circumstances and Lessor shall undertake to restore the Premises to a condition
suitable for the Lessee's use, as near to the condition thereof immediately
prior to such taking as is a reasonably feasible under all the circumstances.

                       (c) In the event of any such taking, or by private
purchase in lieu thereof after a condemnation action has been actually
commenced, Lessor and Lessee shall each be entitled to receive and retain such
separate awards and/or portion of lump sum awards as may be allocated to their
respective interest in any condemnation proceedings; provided that Lessee shall
not be entitled to receive any award for Lessee's loss of its Leasehold
interest, the right to such award being hereby assigned by Lessee to Lessor.

         THIRTIETH: Should Lessee hold over and remain in possession of the
Premises at the expiration of any term hereby created, Lessee shall, by virtue
of this paragraph, become a Lessee by the month at twice the Rent per month of
the last monthly installment of Rent above provided to be paid, which said
monthly tenancy shall be subject to all the conditions and covenants of this
Lease as though the same had been a monthly tenancy instead of a tenancy as
provided herein, and Lessee shall give to Lessor at least fifteen (15) days'
written notice of any intention to remove from the Premises, and shall be
entitled to ten (10) days' notice from Lessor in the event Lessor desires
possession of the Premises; provided, however, that said Lessee by the month
shall not be entitled to ten (10) days' notice in the event the said Rent is not
paid in advance without demand, the usual ten (10) days' written notice being
hereby expressly waived.

         THIRTY-FIRST:  [INTENTIONALLY DELETED].

         THIRTY-SECOND: Lessee shall be entitled to the use of 30 parking spaces

employees or guests, as the Lessee shall determine from time to time. In its
normal course of business, Lessee will not cause more than said number of
parking spaces to be occupied at any one time by its employees or invitees.

         THIRTY-THIRD: Lessee, its successors and assigns shall comply with all
of the laws, rules and regulations regarding the use of hazardous materials in,

or any agency or instrumentality thereof.

         THIRTY-FOURTH: Radon is a naturally occurring radioactive gas that,
when it has accumulated in a building in sufficient quantities, may present
health risks to persons who are exposed to it over time. Levels of radon that
exceed federal and state guidelines have been found in buildings in Florida.
Additional information may be obtained from your county public health unit.

         THIRTY-FIFTH: In any case, where either party hereto is required to do
any act, except the payment of rent or other money, the term for the performance
thereof shall be extended by a period equal to any delay caused by or resulting
from acts of God, the elements, weather, war, civil commotion, fire or other
casualty, strikes, lockouts, labor disturbances, inability to procure labor or
materials, failure of power, government regulations or other causes beyond such
party's reasonable control, whether such time be designated by a fixed date, a

fixtures as it may deem advisable, without altering the basic character of the
Building or improvements and without overloading or damaging such Building or
improvements, and in each case after complying with all applicable governmental
laws, ordinances, regulations and other requirements. All alterations,
additions, improvements and partitions erected by Lessee shall be and remain the
property of Lessee during the term of this Lease and shall become the property
of Lessor as of the date of termination of this Lease, or upon earlier vacating
of the Premises, and title shall pass to Lessor under this Lease as by a bill of
sale. All shelves, bins, machinery and trade fixtures installed by Lessee may be
removed by the Lessee prior to the termination of this Lease, if the Lessee so
elects, and shall be removed by the date of termination of this Lease or upon
earlier vacating of the Premises if required by Lessor; upon any such removal
Lessee shall restore the Premises to a good and Leaseable condition, less
ordinary wear and tear. All such removals and restoration shall be accomplished
in a good workmanlike manner so as not to damage the primary structure, roof or
structural qualities of the Building and other improvements within which the
Premises are situated. If Lessor shall consent to any alterations, additions or
improvements proposed by Lessee, Lessee shall construct and maintain the same to
comply with all then existing governmental laws, ordinances, rules and

                  (2) Subcontracts. Enter into a contract with its contractor
and/or other persons who will do the work and install the equipment referred to,

licenses previously obtained and which contract shall provide that the
contractor, subcontractor, or other person referred to above will look solely to
Lessee for payment and will hold Lessor and the premises free from all liens and
claims of all persons furnishing labor or materials therefor, and will also
provide that similar waivers of the rights to file liens shall be obtained from
any and all said contractors or materialmen. A copy of said contract, together
with a duly executed waiver of the right to file liens executed by the
contractor, subcontractor, or other persons referred above, shall be furnished
to Lessor as a condition of Lessor approving such alterations or installations.

insuring that Lessee and Lessee's contractors, suppliers, and materialman comply

                  (6) Impact Fees. In the event Lessee's alterations to the
Premises cause the City of Miramar to assess impact fees, Lessee shall be solely
responsible for paying same. (In particular, Lessee acknowledges that the
addition of plumbing fixtures may result in water and sewer impact fees being
assessed by the City and that such fees shall be Lessee's sole responsibility to
pay.

              THIRTY-EIGHTH: Tenant Improvements. (a) Lessee and Lessor agree to

Improvements.
