LEASE AGREEMENT

1. PARTIES

     This Lease, dated February 1, 1984, for reference purposes only, is made by
and between Carroll Ridge Park, a California General Partnership (herein called
"Lessor"), and Elgar Corporation, a California Corporation (herein called
"Lessee"). 

2. DESCRIPTION OF PREMISES

     Lessor hereby leases to Lessee and Lessee hires from Lessor on the terms,
covenants and conditions hereinafter set forth, the real property described in
Exhibit "A" attached hereto together with the improvements described below. Said
real property and improvements are described in the map and floor plan attached
hereto as Exhibit "B."  Said real property and improvements are hereinafter
referred to as the leased premises.  Effective on the vacation by the City of
San Diego of Carroll Park Court, the leased premises shall include said Carroll
Park Court. The leased premises are being transferred to Lessee subject to all
those matters set forth in Exhibit "C" attached hereto. 

3. TERM

     3.1  INITIAL TERM - The initial term of this Lease shall be for ten (10)
years commencing on August 1, 1984 (the "commencement date") and ending on July
31, 1994, unless sooner terminated pursuant to any provision hereof.

     3.2  OPTION TO RENEW - Lessee shall have the option to extend the Lease for
two (2) additional periods of five (5) years each. Lessee may exercise its right
to extend for the first option term by notifying Lessor of its election to so
extend no later than sixty (60) days prior to the termination of the initial
Lease term period and no earlier than six (6) months prior to said termination
and for the second option term by giving notice not later than sixty (60) days
prior to the termination of the term under the first option and no earlier than
six (6) months prior to said termination. Provided, however, Lessee shall have
no extension right if at the time for giving such notice or at the commencement
of such extension there exists any uncured default hereunder by Lessee for which
Lessee has received ten (10) days prior written notice from Landlord. All terms
and conditions of this Lease shall remain in full force and effect during the
option term except that the rent payable hereunder by Lessee to Lessor for the
first year of each option term shall be adjusted to the fair market rental of
the land and building (but excluding all Lessee's Improvements) as of the
commencement of each option term. For purposes of this Lease, unfair market
rental shall be determined by agreement between the parties within ten (10) days
after Lessee notifies Lessor of its intention to exercise the Option hereunder.
If within said ten (10) days the parties are unable to agree upon a "fair market
rental," then each shall select an appraiser within five (5) days thereafter
with a designation of "M.A.I." or in the event M.A.I., appraisers are no longer
available, a comparable designation and within five (5) days after such
appointment, the two appraisers shall agree upon a third appraiser. Within
thirty (30) days thereafter, the appraisers shall notify the parties in writing
their appraisal of the fair market rental and the average of the two




appraisals, which are closest in amount shall be deemed the fair market rental.
Each party shall pay the cost of its own appraiser and the parties shall share
the cost of the third appraiser. In the event the appraisals are not returned to
the parties prior to the commencement of the option term, Lessee shall continue
to pay rent at the then current rate until the determination of the fair rental
value whereupon the rent shall be adjusted retroactively to the fair market
rental and any additional amounts shall be paid to the Lessor by Lessee with the
next regular monthly payment following such determination. For a period of one
hundred twenty (120) days after the determination of the fair market rental by
the parties, as set forth above Lessee shall have the right to terminate the
Lease by delivering written notice to Lessor of its election to so terminate. In
the event, such notice is delivered to Lessor within said one-hundred twenty
(120) day period; the Lease shall terminate sixty (60) days thereafter. Lessee
shall be responsible for the payment of rent to Lessor in the amount determined
to be the fair market rental until the date of such termination.

     3.3       COMMENCEMENT AND POSSESSION - Notwithstanding the commencement
date, Lessor shall deliver to Lessee Possession (as defined below) of the
manufacturing warehouse portion of the leased premises consisting of
approximately 44,000 square feet on or before July 1, 1984 and Possession of the
office portion of the leased premises consisting of approximately 43,000 square
feet on or before September 1, 1984. For purposes of this Section 3.3, the term
"Possession" shall mean the earlier to occur of (i) the tender of actual
physical possession of the leased premises by Lessor to Lessee accompanied by a
Certificate of occupancy from the City of San Diego or an agreement from the
City of San Diego that the leased premises may be occupied without such
Certificate, or (ii) the operation of Lessee's business from the leased
premises. If Lessor shall not have completed and delivered Possession of the
entire leased premises within one hundred twenty (120) days from the
commencement date, Lessee may, at Lessee's option, by notice in writing to
Lessor within ten (10) days thereafter, cancel this Lease, in which event the
Parties shall be discharged from all obligations hereunder. If Lessee occupies
the leased premises prior to the commencement date, such occupancy shall be
subject to all provisions hereof except payment of rent. Notwithstanding
occupancy or the date of delivery of Possession, neither the commencement date
nor the termination date hereunder shall be delayed or advanced. Lessor
acknowledges and agrees that its failure to deliver Possession of the leased
premises to Lessee at the time and in the manner set forth above shall cause
Lessee damage in an amount which would be impractical or difficult to calculate,
but a reasonable estimate of, which would be Five Hundred Dollars ($500.00) for
each day after July 1, 1984 and until delivery of Possession of the
manufacturing warehouse, and Two Hundred Dollars ($200.00) for each day after
September l, 1984 and until delivery of Possession of the office facilities.
Therefore, Lessor and Lessee agree that, in addition to Lessee's right to cancel
the Lease as set forth above and the reduction of rent as set forth in Section
4.1, in the event of the delay in delivery of Possession to Lessee, Lessor shall
pay liquidated damages to Lessee in the amount of Five Hundred Dollars ($500.00)
per day for each day of delay after July 1, 1984 with respect to the
manufacturing warehouse and Two Hundred Dollars ($200.00) per day for each day
after September 11, 1984, with respect to the office building until the Lease is
terminated if terminated as set forth above. Lessor's obligations hereunder are
subject to any extensions pursuant to the force majeure clause set forth in the
General Provisions below. 


                                          2


4. RENT

     4.1  MONTHLY RENTAL - Lessee agrees to pay Lessor fixed monthly rent for
the building structure of $0.54 per square foot based upon the number of square
feet of the entire leased premises as built. Based upon the agreed area of the
entire leased premises of 87,000 square feet, the total fixed monthly rent shall
be $46,980. Fixed monthly rent shall be payable in advance, without prior notice
or demand and without set off or deduction, in lawful money of the United States
of America. Subject to Section 3.2 above, rent shall commence on August 1, 1984
with the first payment thereof due on August 10, 1984 in the amount of
Fifty-Eight Thousand Seven Hundred Twenty-Five Dollars ($58,725.00) for the
period from August 1, 1984 to September 9, 1984 and thereafter rent in the
amount of Forty-Six Thousand Nine Hundred Eighty Dollars ($46,980.00) per month
for the period from the 10th of such month to the 10th of the next month shall
be paid on the 10th day of each and every calendar month during the term hereof.
Provided however, if Possession of the office portion of the leased premises is
not tendered to Lessee on or before September 1, 1984, a pro-rata portion of the
rent here under shall be abated by 49.4% for each day of delay retroactive to
August 1, 1984, until the time such Possession is tendered to Lessee; and if
Possession of the manufacturing portion of the leased premises is not tendered
to Lessee on or before July 1, 1984, a pro-rata portion of the rent hereunder
shall be abated by 50.6% for each day from July 1, 1984, until the time such
Possession is tendered to Lessee. Provided further, if Possession of the office
portion of the leased premises is tendered to Lessee on or before September 1,
1984, Lessee shall pay as additional rent to Lessor an amount equal to 49.4% of
a pro-rata portion of the rent for each day prior to September 1, 1984 that such
Possession is tendered to Lessee.

     4.2       RENTAL ADJUSTMENT - The fixed monthly rent under Section 4.1 of
this Lease shall be subject to adjustment upwards only at the end of each one
year period of the lease term hereof including option periods, if any. For the
first month of the second year, as determined by Section 3.1 of this Lease, and
the first month of every year thereafter for the duration of this Lease the
monthly rental for the ensuing twelve (12) months shall be adjusted upward only
at the rate of five percent (5%) per year, using the monthly rental of the
previous year as the base to calculate such increase. The rent so fixed and
adjusted shall be the rent for the one-year period commencing with the date on
which said rent is to be adjusted as herein provided. The rent for the last
month prior to the adjustment date shall be increased by the pro-rata increase
in the rent for the first ten (10) day of the next succeeding month. Provided,
however, if one or both of the options to extend the Lease are exercised by
Lessee the adjustment for the first year of each option term shall be as
provided in Section 3.2 rather than this Section 4.2. 

5. CONSTRUCTION

     5.1       LESSOR'S IMPROVEMENTS - Lessor agrees that subject to the force
majeure clause in the General Provisions below, it will at its own cost and
expense construct and deliver possession of a building and other improvements
on, the leased premises to Lessee on the dates specified in Section 3.3 above
consisting of all specifications (the "Lessor's improvements") set forth in the
following plans:

          (d)  Beckett and Wong pages Sl-10 inclusive Job #2881.

          (e)  Landscaping Plans and Specifications prepared by Lessor and
approved by Lessee, which approval will not be unreasonably withheld. Lessor
shall deliver such plans and specifications to Lessee on or before February 15,
1984 and Lessee shall have ten (10) working days thereafter to notify Lessor of
its disapproval of such plans and specifications or the same shall be deemed
approved. The term "working days" shall include the days Monday through Friday
only. If Lessee disapproves said plans and specifications within said ten (10)
working day period and the parties are unable to agree upon plans and
specifications within five (5) days thereafter, they shall submit the matter to
arbitration in San Diego County within twenty (20) days thereafter in accordance
with the rules of the American Arbitration Association. Any delays caused
hereunder shall not relieve the Lessor of its obligations under Section 3.3
hereof nor affect Lessee's right to liquidated damages and abatement of rent.

     The above plans and specifications may not be altered or modified except
for nonmaterial field changes or requirements of the City of San Diego, without
the prior written consent of Lessee, which consent shall not be unreasonably
withheld.

     5.2  LESSEE'S IMPROVEMENTS - Lessee shall, at its own cost and expense,
provide Lessor with plans and specifications for completion of interior
improvements to the building on the leased premises to the satisfaction of
Lessee (hereinafter referred to as "Lessee's Improvements"). Lessee shall
deliver to Lessor the plans and specifications for Lessee's Improvements in the
manufacturing portion of the leased premises on or before February 15, 1984 and
in the office portion of the leased premises on or before April 1, 1984, thirty
(30) days after receipt of the respective plans and specifications, Lessor shall
provide Lessee with a written construction cost bid on the Lessee's Improvements
from Lessor's contractor. Within fifteen (15) days thereafter, Lessee shall have
the right to approve or disapprove such bid. Failure of Lessee to either approve
or disapprove such bid in writing within said fifteen (15) day period shall be
deemed an approval by Lessee. In the event, Lessee disapproves such bid, Lessor
shall have no responsibility with respect to the Lessee's Improvements and
Lessee will be required to construct Lessee's Improvements without the
assistance of Lessor. Also, in the event Lessee disapproves such bid, the term
"Possession" as used in Section 3.3 shall be redefined to mean actual tender
possession of the premises with substantial completion and the recordation of a
Notice of Completion. If Lessee elects to provide its own Lessee's improvements,
Lessor shall allow Lessee access to the building on or before June 1, 1984 for
installation of Lessee's Improvements. Lessee and Lessor shall cooperate in
installation of the Lessee's Improvements and Lessee shall do nothing to delay,
hinder, or interfere with Lessor's construction hereunder. In the event, Lessee
approves such bid; Lessor shall have the responsibility to construct Lessee's
Improvements on the terms set forth below:


                                          4


          (a)  Lessor shall construct Lessee's Improvements in accordance with
     the plans and specifications submitted by Lessee prior to the dates upon
     which Lessor is to tender possession of the Leased Premises to Lessee under
     Section 3.3. Lessor's failure to complete the Lessee's Improvements at the
     times set forth in Section 3.3 shall entitle Lessee to all rights and
     remedies under Section 3.3 including liquidated damages. Provided, however,
     it shall be Lessee's responsibility to obtain from the City of San Diego
     approval for such plans and specifications for Lessee's Improvements in the
     manufacturing warehouse portion of the leased premises and deliver the same
     to Lessor on or before April 1, 1984 and for Lessee's Improvements in the
     office portion of the leased premises and deliver the same to Lessor on or
     before June 1, 1984. In the event Lessee fails to obtain such approvals by
     such dates, the dates upon which possession is to be tendered under Section
     3.3 hereof shall be delayed one day for each day such approvals are
     delayed.

          (b)  Lessor shall complete the Lessee's Improvements for a cost not to
     exceed the bid price plus any change orders approved in writing by Lessee,
     which approval will not be unreasonably withheld. Lessee shall be
     responsible to pay all City and utility fees with respect to the
     construction of Lessee's Improvements directly to the City. All other costs
     and fees for Lessee's Improvements shall be paid by Lessor to the
     contractor. Lessee agrees to pay Lessor the amounts required by the
     contractor (to the extent those amounts do not exceed the bid price or any
     approved changes) within twenty (20) days after receipt from Lessor of
     invoices from the contractor.

     All Lessees' Improvements shall be and remain the property of Lessee until
termination or expiration of the Lease at which time they shall immediately
become the property of Lessor. Provided, however, if the Lease is terminated by
Lessee pursuant to Section 3.3 hereof, Lessor shall reimburse Lessee the amounts
paid by Lessee to Lessor for such Improvements to the extent Lessor is benefited
by such Improvements.

6.  USE AND QUIET ENJOYMENT

     6.1  The Lessee may use and occupy the leased premises for manufacturing

nor for any business, use or purpose deemed disreputable or extra-hazardous, nor

17. ASSIGNMENT AND SUBLETTING

     CONSENT REQUIRED - Lessee will not assign this Lease in whole or in part,
nor sublet all or any part of the leased premises, without the prior written
consent of Lessor in each instance, which prior written consent Lessor agrees it
will not unreasonably withhold or delay.  The consent by Lessor to any
assignment or subletting shall not constitute a waiver of the necessity for such
consent to any subsequent assignment or subletting. This prohibition against
assigning or subletting shall be construed to include a prohibition against any
assignment or subletting by operation of law. If this Lease be assigned, or if
the leased premises or any part thereof be sublet or occupied by anybody other
than Lessee, Lessor may collect rent from the assignee, sublessee or occupant,
and apply the net amount collected to the rent herein reserved, but no such
assignment, subletting, occupancy or collection shall be deemed a waiver of this
covenant, or the acceptance of the assignee, sublessee or occupant as Lessee, or
a release of Lessee from the further performance by Lessee of covenants on the
part of Lessee herein contained. Notwithstanding any assignment or sublease,
Lessee shall remain fully liable on this Lease and shall not be released from
performing any of the terms, covenants and conditions of this Lease. Lessee may
assign this Lease as part of a merger, sale of assets or other corporation
reorganization to a parent subsidiary or successor corporation. 

18. DEFAULT OF THE LESSEE

     18.1      DEFAULT - The occurrence of any of the following shall constitute
a material default of this Lease by Lessee:

          (a)  Any failure by Lessee to pay the rent or any other monetary sums
     required to be paid hereunder;

          (b)  The abandonment or vacation of the leased premises by Lessee;

          (c)  A failure by Lessee to observe and perform any other provision of
     this Lease to be observed or performed by Lessee where such failure
     continues for thirty (30) days after written notice thereof by Lessor to
     Lessor provided however, that if the nature of such default is such that
     the same cannot reasonably be cured within such thirty (30) day period,
     Lessee shall within such period commence such cure and thereafter
     diligently prosecute the same to completion;

          (d)  The making by Lessee of any general assignment or general
     arrangement for the benefit of creditors; the filing by or against Lessee
     of a petition to have Lessee adjudged a bankrupt or of a petition for
     reorganization or arrangement under any law relating to bankruptcy (unless,
     in the case of a petition filed against Lessee, the same is dismissed
     within sixty (60) days); the appointment of a trustee, or receiver to take
     possession of substantially all of Lessee's assets located at the leased
     premises or of Lessee's interest in this Lease where possession is not
     restored to Lessee within sixty (60) days; or the attachment execution or
     other judicial seizure of substantially all of Lessee's assets located at
     the leased premises or of Lessee's interest in this Lease, where such
     seizure is not discharged within sixty (60) days.


                                          10


     18.2      REMEDIES IN EVENT OF DEFAULT - In the event of any such material
default by Lessee, Lessor may at any time thereafter, with or without notice and
demand and without limiting Lessor in the exercise of any right or remedy at law
or in equity which Lessor may have by reason of such default or breach:

          (a)  Maintain this Lease in full force and recover the rent and other
     monetary charges as they become due, with the right to sue monthly or
     periodically at its election, without terminating the Lessee's right of
     possession, irrespective of whether Lessee shall have abandoned the leased
     premises. In the event Lessor elects not to terminate the Lease, Lessor
     shall have the right to attempt to relet the leased premises at such rent
     and upon such conditions and for such a term and to do all acts necessary
     to maintain or preserve the leased premises as Lessor deems reasonable and
     necessary without being deemed to have elected to terminate the Lease
     including removal of all persons and property from the leased premises;
     such property may be removed and stored in a public warehouse or elsewhere
     at the cost of and for the account off Lessee. In the event any such
     releting occurs, this Lease shall terminate automatically upon the new
     Lessee taking possession of the leased premises. Notwithstanding that
     Lessor, fails to elect to terminate the Lease initially, Lessor at any time
     during the term of this Lease may elect to terminate this Lease by virtue
     of such previous default of Lessee.

          (b)  Terminate Lessee's right to possession by any lawful means, in
     which case this Lease shall terminate and Lessee shall immediately
     surrender possession of the leased premises to Lessor. In such event Lessor
     shall be entitled to recover from Lessee all damages incurred by Lessor by
     reason of Lessee's default including without limitation thereto, the
     following: (i) the worth at the time of award of any unpaid rent which had
     been earned at the time of such termination; plus, (ii) the worth at the
     time of 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 is proved by Lessee could have been reasonably avoided;
     plus, (iii) the worth at the time of award of the amount, which the unpaid
     rent for the balance of the term after the time of award exceeds the amount
     of such rental loss that is provided by Lessee could be reasonably avoided;
     plus (iv) any other amount necessary to compensate Lessor for all the
     detriment proximately caused by Lessee's failure to perform his obligation
     under the Lease or which in the ordinary course of things would be likely
     to result  therefrom; plus (v) at Lessor's electric, such other amounts in
     addition to or in lieu of the foregoing is may be permitted from time to
     time by applicable state law. Upon any such reentry, Lessor shall have the
     right to make any reasonable repairs, alterations or modifications to the
     leased premises, which Lessor in its sole discretion deems reasonable and
     necessary. As used in the subparagraphs (i) and (ii) above, the "worth at
     the time of award" is computed by allowing interest at the rate of ten
     percent (10%) per annum from the date of default. As used in subparagraph
     (iii) above, the "worth at the time of award" is computed by discounting
     such amount at the discount rate of the Federal Reserve Bank of San
     Francisco at the time of award plus one percent (1%). The term "rent," as
     used in this Section, shall be deemed to be and to mean the rent to be


                                          11


     paid pursuant to Section 4 and all other monetary sums required to be paid
     by Lessee pursuant to the terms of this Lease.

     18.3      LEGAL EXPENSE -  In case suit shall be brought for enforcement
rights under this Lease, or because of the breach of any other covenant herein
contained, the losing party shall pay to the prevailing party all expenses
incurred therefore, including reasonable attorneys' fees. 

19. DESTRUCTION

     In the event of (a) a partial or total destruction of the leased premises
or the building containing same during said term which requires repairs to
either the leased premises or said building, or (b) the leased premises or said
building being declared unsafe or unfit for occupancy by any authorized public
authority for any reason other than Lessee's act, use or occupation which
declaration requires repairs to either the leased premises or said building.
Lessor shall forthwith make such repairs, including Lessee's Improvements and
alterations (unless Lessee elects to make such repairs), provided such repairs
can be made within one hundred twenty (120) days under the laws and regulation
or authorized public authorities, but such destruction (including any
destruction necessary in order to make repairs required by any such declaration)
shall in no way annul or void this Lease, except that Lessee shall be entitled
to a proportionate reduction of rent while such repairs are being made, such
proportionate reduction to be based upon the extent to which the damage and
making of such repairs shall interfere with the business carried on by Lessee on
the leased premises; provided that in making such repairs, with regard to
glazing Lessor shall be obligated to replace only such glazing as shall have
been damaged by fire and other damaged glazing shall be replaced by Lessee. In
making such repairs, Lessor shall be entitled to all insurance proceeds from any
policies hereunder, which are applicable to such repairs. Within thirty (30)
days from the date of such destruction if Lessor determines in good faith such
repairs cannot be made within one hundred twenty (120) days, it shall so notify
Lessee in writing and state the estimated number of days for repair. Within
seven (7) days after receipt of Lessor's notice Lessee may terminate the Lease
upon thirty (30) days notice to Lessor if Lessee does not terminate the Lease in
this manner, Lessor shall use its best efforts to make all repairs in the time
set forth in its notice to Lessee. Notwithstanding the above, Lessor shall not
be required to proceed with repairs if there are not sufficient insurance
proceeds to cover such repairs. In such event Lessee shall have the right to (i)
terminate the Lease upon thirty (30) days notice to Lessor, (ii) continue the
Lease without repair, or (iii) to pay for that portion of the repairs not
covered by insurance. 

20. SURRENDER OF LEASE NOT MERGER

     The voluntary or other surrender of this Lease by Lessee, or a mutual
cancellation thereof, shall not work a merger, and shall, at the option of
Lessor, terminate all or any existing subleases, and/or subtenancies, or may, at
the option of Lessor, operate as an assignment to them of any or all of such
subleases or subtenancies. 

21. CONDEMNATION


                                          12


     If any part of the leased premises shall be taken or condemned for a public
or quasi-public use, and a part thereof remains which is susceptible of
occupation hereunder, this Lease shall, as to the part so taken, terminate as of
the date title shall vest in the condemnor, and the rent payable hereunder
shall, be adjusted so that the Lessee shall be required to pay for the remainder
of the term only such portion of such rent as the fair market value of the part
remaining after the condemnation bears to the rental value of the entire leased
premises at the date of condemnation; but in such event Lessor shall have the
option to terminate this Lease as of the date when title to the part so
condemned vests in the condemnor. If all the leased premises or such part
thereof be taken or condemned so that there does not remain a
portion-susceptible for occupation hereunder, this Lease shall thereupon
terminate. If a part or all of the leased premises be taken or condemned, all
compensation awarded upon such condemnation or taking shall go to the Lessor and
the Lessee shall have no claim thereto, and the Lessee hereby irrevocably
assigns and transfers to the Lessor any right to compensation or damages to
which the Lessee may be entitled during the term hereof by reason of the
condemnation of all, or a part of the leased premises. Any dispute between
Lessor and Lessee concerning the provisions of this paragraph shall be submitted
to arbitration in accordance with the rules of the American Arbitration
Association. However, Lessee shall be entitled to any award for its trade
fixtures, relocation expenses, business losses and disruption. 

22. GENERAL PROVISIONS

subsequent transfers the then grantor) shall be relieved from and after the date
of such transfer of all liability as respects Lessor's obligations thereafter to
be performed, provided that any funds in the hands of Lessor or then grantor at
the time of such transfer, in which Lessee has as interest, shall be delivered

shall be in writing and may be served personally or by certified mail, return

after deposit in the United States mail. Either party may by notice to the other
specify a different address for notice purposes except that upon Lessee's taking
possession of the leased premises, the leased premises and Lessee's address
beneath its signature at the end of this Lease shall both constitute Lessee's
addresses for notice purposes.

     22.9      WAIVER - No waiver by Lessor of any provision hereof shall be
deemed a waiver of any other provision hereof or of any subsequent breach by
Lessee of the same or any other provision. Lessor's consent to or approval of
any act shall not be deemed to render unnecessary the obtaining of Lessor's
consent to or approval of any subsequent act by Lessee.

personal representatives, successors and assigns; it shall be governed by the
laws of the State of California.

trust or any other hypothecation for security now or hereafter placed upon the
real property of which the leased premises are a part and to any and all
advances made on the security, thereof and to all renewals, modifications,
consolidations, replacements and extensions, thereof. Notwithstanding such
subordination, Lessee's right to quiet possession of the leased premises shall
not be disturbed if Lessee is not in default and so long as Lessee shall pay the
rent and observe and perform all of the provisions of this Lease, unless this
Lease is otherwise terminated pursuant to its terms. If any mortgagee, trustee
or ground Lessor shall elect to have this Lease prior to the lien of its
mortgage, deed of trust or ground lease, and shall give written notice thereof
to Lessee, this Lease shall be deemed prior to such mortgage, deed of trust, or
ground lease, whether this Lease is dated prior or subsequent to the date of
said mortgage, deed of trust or ground lease or the date of recording thereof.

required to effectuate such subordination or to make this Lease prior to the
lien of any ground lease, mortgage or deed of trust, as the case may be, within
ten (10) days after written demand. Provided, any such document reflects the
fact that Lessee may continue its right of quiet possession in the leased
premises in the event of any foreclosure if it attorns to the purchaser at any
foreclosure sale.

     22.16     FORCE MAJEURE - Any prevention, delay or stoppage due to enemy or
hostile governmental action, civil commotion, fire or other casualty, other
similar acts of God, or extraordinary material shortages, which are-beyond the
reasonable control of the party obligated to perform, or which are caused by the
acts of the other party or the failure of the other party to fulfill its
obligations under this Lease, shall excuse the performance by such party for a
period equal to any such prevention, delay or stoppage.

     22.17     NO OPTION - The submission of this Lease for examination does not
constitute a reservation of or option for the leased premises and this Lease
becomes effective as a Lease only upon execution and delivery thereof by Lessor
and Lessee.


                                          15


     22.18     COVENANT AND WARRANTY OF PRIOR USE - Lessor hereby covenants,
represents and warrants to Lessee that to Lessor's knowledge the leased premises
have been raw acreage and not used in any other manner, and will not be used in
any other manner, prior to the commencement of the Lease. Specifically, Lessor
represents and warrants that it has no knowledge of any toxic waste or other
dumping that has taken place on the leased premises.

23. OPTION TO PURCHASE

     Lessor hereby grants to Lessee an option to purchase the leased premises on
or before July 31, 1984 for a purchase price and on terms and conditions
mutually agreeable between the parties. Lessee may exercise this option by
delivering notice of such exercise to Lessor on or before July 1, 1984. Within
thirty (30) days after receipt of said notice, the parties agree to negotiate in
good faith to attempt to establish the price, terms and conditions of the sale
of the leased premises from Lessor to Lessee. The parties agree and acknowledge
that the covenants set forth in this Section 24 are independent of those set
forth elsewhere in the Lease. In the event, the provisions of this Section 24
are held to be invalid or unenforceable for any reason, it shall in no way
affect any other provision of this Lease. 

24. RIGHT OF FIRST REFUSAL

     If Lessor desires to exchange, sell, ground lease, option or otherwise
transfer excluding encumbrances, ("Transfer") or agree to Transfer all or any
part of the leased premises, Lessor shall first notify Lessee in writing of the
price and/or terms on which Lessor will Transfer. If Lessee, within thirty (30)
days after Lessor's notice has been delivered indicates in writing its agreement
to acquire the leased premises, on the terms stated in Lessor's notice, Lessor
shall Transfer the leased premises to for the price and/or on the terms stated
in Lessor's notice, except that in the event of an exchange Lessee may elect to
pay Lessor the equity value of Lessor's property rather than exchange for "like
kind" property; provided that Lessee will reasonably cooperate with Lessor in
any exchange if it is at no added cost or expense to Lessee. If Lessee does not
indicate its agreement in writing within said thirty (30) days; Lessor shall
have the right to transfer the leased premises to any purchaser, tenant or
optionee on the-same terms as stated in the notice in the event of a proposed
Transfer of the property, if Lessor does not enter into a binding contract and
escrow to Transfer within six (6) months from the date Lessor's notice is
delivered to Lessee, or in any event, if Lessor does not actually Transfer the
property within nine (9) months after Lessor's notice is delivered to Lessee any
further transaction shall be deemed a new determination by Lessor to Transfer
the leased premises and the provisions of this right of first refusal shall be
applicable. If Lessor receives an offer with respect to a Transfer of the leased
premises within said six (6) month period which is on price or financial terms
different from those set forth in Lessor's notice to Lessee, before accepting
such offer Lessor shall first notify Lessee in writing of the terms of the
offer. If Lessee, within fifteen (15) days after Lessor's notice of such
different terms has been delivered, indicates in writing its agreement to accept
the Transfer of the leased premises, Lessor shall Transfer the leased premises
to Lessee for the price and on the terms stated in the notice. If Lessee does
not indicate its agreement within said fifteen (15) days, Lessor shall have the
right


                                          16


to Transfer the leased premises to the purchaser on the terms of the notice
provided such Transfer is completed within the nine (9) month period mentioned
above.

     IN WITNESS WHEREOF, Lessor and Lessee each by its duly authorized officer
have signed and sealed this Lease as of the day and year first above written.
