ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On June 17, 1996, the Company completed the sale of all of the issued
and outstanding capital stock of Morehouse-COWLES, Inc. to J.B. Jennings and
Bret Lewis, a private investment group based in Michigan. The Closing of the
sale of Morehouse-COWLES, Inc. by the Company was publicly announced on June 17,
1996, by means of the press release attached hereto as Exhibit 99 and
incorporated herein by this reference. The Company will not report a gain or
loss on the sale.

         In exchange for all of the capital stock of Morehouse-COWLES, Inc., the
Company was paid $750,000 in cash and will be paid an additional $1,771,000 on
the terms and conditions set forth in a subordinated promissory note.  The
subordinated note provides for the payment of interest monthly at the rate of 7%
per annum through June, 2001, and at the rate of 9% per annum through June 2006,
and provides for monthly principal payments commencing July 2001 utilizing a 10-
year amortization schedule with all unpaid interest and principal due and
payable by June 30, 2006.  The note is subordinated to the investors' bank
credit agreement, permits optional prepayments, contains certain covenants and
default provisions and remedies and is secured by a pledge of all of the
outstanding capital stock of Morehouse-COWLES purchased by the investors, as
well as by the assets of Morehouse-COWLES, Inc.  Additionally, the investment
group entered into a new lease with the wholly-owned subsidiary of the Company
that holds title to the Company's Fullerton facilities, in which the operations
of Morehouse-COWLES also have been conducted.  The lease is for a period of ten
years, with an option to extend the term of the lease for an additional five
years.  The monthly rent, on a "triple net basis," will be $4,000 during the
first five years of the lease, increasing to $5,000 per month during the second
five years of the original lease term.

         On January 30, 1996, the Company had previously announced that it had
entered into a letter of intent to sell Morehouse-COWLES to another prospective
purchaser, but negotiations with that buyer were subsequently terminated as
reported in the Company's Quarterly Report on Form 10-Q for the quarter ended
February 29, 1996.  However, as also reported in that Quarterly Report on Form
10-Q, the Company announced that it would continue seek to sell the industrial
process equipment business conducted by Morehouse-COWLES, Inc.  Accordingly, the
Company announced that Morehouse-COWLES, Inc. would be treated for accounting
purposes as a discontinued operation, and the results of its operations were
segregated in the financial statements of the Company set forth in the Quarterly
Report.

default of any obligation to be performed under a Benefit Plan or has done any
act which solely by notice and/or passage of time will become a material default
of any obligation to be performed thereunder.

     Each Benefit Plan listed in the Disclosure Schedule which is subject to
ERISA ("ERISA Plans") complies in all material respects with the requirements of
ERISA.  Each such ERISA Plan which is a pension plan has been determined by the
Internal Revenue Service to be qualified under Section 401(a) of the Code; no
such pension plan has engaged in a "prohibited transaction", as that term is
defined in Section 4975 of the Code, which could subject the Company to a
material tax or penalty on prohibited transactions under Section 4975 of the
Code; all required reports and returns have been filed with the appropriate
governmental authorities, there has not been a complete termination of any of
the pension plans, and no proceeding to bring about any such termination has
been instituted; except as listed on the Disclosure Schedule, there have not
been any "reportable events", as that phrase is defined in Section 4043 of
ERISA, for which the 30-day requirement period has not been waived under
regulations promulgated by the Pension Benefit Guaranty Corporation; no
liability to the Pension Benefit Guaranty Corporation has been incurred with
respect to the pension plans except for required premium payments which have
been paid when due; and except as listed on the Disclosure Schedule, none of the
pension plans has incurred any "accumulated funding deficiency", as that phrase
is defined in Section 302 of ERISA (whether or not waived), since the effective
date of that Section.  None of the ERISA Plans is a multiemployer plan within
the meaning of section 3(37) of ERISA, and the Company has never contributed to,
or otherwise participated in, such a plan.  Except as set forth in the
Disclosure Schedule or elsewhere in this Agreement, the Company is not a party
to any written or oral (a) contract or agreement with any labor organization;
(b) contract for the employment of any officer or employee or group of the
Company's employees; (c) consulting or non-competition agreement; (d) agreement
for the construction of plants or facilities or associated architectural,
engineering or other services; (e) distributor, dealer, vendor, manufacturer's
representative, sales agency or advertising contract which is not cancelable on
thirty (30) days' (or less) notice without premium or penalty; (f) contract for
the purchase or sale of materials, supplies, merchandise or other assets or
services involving in the aggregate an obligation of more than $10,000 or
extending (or which may extend) beyond December 31, 1996; (g) agreement granting
any preferential rights to purchase any of its assets, property or rights or
requiring the consent of any party to the transfer or assignment of such assets,
property or rights or limiting or restricting in any other way Company's ability
to transfer or assign such rights; (h) agreement, contract or indenture relating
to the borrowing or lending of money or guarantee of any obligation for borrowed
money or otherwise; (i) any license or other Intellectual Property agreement; or
(j) any other contract, agreement or arrangement, whether or not entered into in
the ordinary course of business, involving in the aggregate, an estimated total
payment in excess of $10,000.  Except as otherwise disclosed in this Agreement
or in the Disclosure Schedule, there is no contract, agreement, plan or other
instrument referred to above that (assuming any notice required by the terms of
such contract, agreement, plan or other instrument is timely given, and the
Seller hereby agrees to provide any such notice) would be modified, subject to
termination or otherwise affected by the transactions contemplated hereby.

harmless the Buyer and any affiliate thereof and the directors, officers, and

claims, costs, damages or liabilities, including reasonable attorneys' fees,
arising out of or relating to (i) the untruth or inaccuracy of any
representation or warranty given in this Agreement by the Seller; (ii) any
breach of any covenant or obligation made by Seller herein; (iii) any and all
damages, losses, costs and expenses resulting from, occasioned by or arising out
of the breach of any representation or warranty, or the nonfulfillment of any

                                       15
<PAGE>
 
               (i) with respect to any and all liabilities and obligations of
     the Company for products liability and similar claims, Seller shall only be
     liable to indemnify Buyer on account thereof if the injury giving rise to
     the claim occurred prior to the Closing and an executive officer of Seller
     had received actual notice of such claim prior to Closing and Seller failed
     to disclose such claim in writing to Buyer on or before the Closing date;
     and

               (ii) Seller shall not be obligated to indemnify Buyer until the
     aggregate amount subject to indemnity exceeds all amounts received as
     insurance reimbursements and/or reflected as reserves on the Financial
     Statements (no matter how characterized thereon) by $25,000, and then only
     to the extent of such excess.

          (c)  Procedure.  Any party seeking indemnification hereunder (the
               ---------                                                   
"Indemnitee") agrees to notify the other (the "Indemnitor") promptly (but in no
event later than sixty (60) days) after discovery of any fact or circumstance
reasonably indicating that there may be a basis for a claim of indemnification
pursuant to this Section 9 (the "Claim" or "Claims").  Any such notice must be
sent by the Indemnitee prior to the expiration of the periods specified in
Section 9(a) hereof.  The notice, to the extent the Indemnitee practically can,
shall describe the nature of the Claim, if the Claim is determinable, the amount
of the Claim, or if not determinable, the Indemnitee's estimate of the amount of
the Claim.  Indemnitee further agrees to minimize the amount of its loss or
injury for which it is entitled to indemnification pursuant to this Section 9 to
the extent practicable.  If Indemnitee, in order to fulfill its obligations to
the Indemnitor under the preceding sentence, must take legal action or if
Indemnitee is involved in any legal action, the outcome of which could give rise
to its seeking indemnification from the Indemnitor pursuant to this Section 9,
and the Indemnitor shall have acknowledged its obligations to indemnify
Indemnitee hereunder, the Indemnitor shall have the right (but not the
obligation) to control any such legal action and proceedings at its own cost and
expense.  The Indemnitee shall nevertheless have the right to participate in all
phases of any such controlled legal action at its own expense.  No settlement,
compromise or other resolution of such controlled litigation shall be had
without the written consent of the Indemnitee, such consent not to be
unreasonably withheld.  The Indemnitor will not be liable under this Section 9
for any Claim in respect of which no such notice is given with the applicable
time period set forth in Section 9(a) and (c).

     No Claim for which indemnification is asserted hereunder shall be settled
or compromised without the written consent of the Indemnitor.

          (d)  Suspension of Limitation Period.  Notwithstanding anything
               -------------------------------                           
contained in this Section 9 to the contrary with respect to the time periods for
indemnification, if a written notice is sent to a party prior to the end of any
applicable time period specified in Section 9(a), the provisions of this Section
9 shall survive the end of any such time period and continue in full force and
effect with respect to any demands, suits, claims, actions or causes of action,
assessments, losses, damages, liabilities, costs and expenses including, without
limitation, interest, penalties and attorneys' fees asserted against, resulting
to, imposed upon or incurred by Indemnitee by reason of or resulting from the
subject matter contained in such notice.

                                       16

          (e) In the event either party seeks indemnity payments from the other,
the parties will, for a period of 30 days after receipt of demand for such
payment, use their respective best efforts to arrive, in good faith, upon an
agreeable resolution of the claim.  In the event that no agreement is reached
during such 30-day period, the party seeking indemnification shall be entitled
to pursue whatever legal remedies it may have.

          (f) Set Off.  Each party shall have the right to set off any amounts
              -------                                                         
finally determined by a competent tribunal to be due to the other under this
Section against any amount owed such party to the other.

          (g) Limitation on Indemnification.  Except as otherwise expressly
              ------------------------------                               
provided below in this subsection 9(g), the maximum aggregate liability of
Seller to Buyer as a consequence of any one or more breach or breaches of one or
more of the representations and warranties of Seller contained herein shall be
limited to the aggregate amount paid and payable to Seller as the aggregate
Purchase Price for the Shares. In the case of actual fraud, Buyer may, in
addition to the foregoing right of indemnification, pursue any and all legal and
equitable remedies it may have against Seller.

reasonable services as Seller may reasonably request to facilitate the
relocation of Seller's executive offices from the premises that are the subject
of the Lease, it being understood and agreed that Seller will reimburse the
Company for any and all out-of-pocket direct costs paid by the Company in

at no charge except for reimbursement to the Company for any and all out-of-
pocket direct costs incurred in connection therewith.

          (f) Any and all payments made by Buyer to Seller, no matter how
designated or described by Buyer, shall be applied to amounts owing by Buyer to
Seller first to any and all payments then due and payable under the Note, then
to any and all payments then due and owing under the Lease; and then to any and
all payments then due and owing under the License Agreement; and

          (g) The Company shall provide to Seller quarterly financial statements

Purchase Price (as defined therein) for the Shares is to be paid by Makers to
Payee pursuant to the terms and conditions this Agreement, the form of which is
attached as Exhibit B to the Stock Purchase Agreement.

     B.  This Agreement is being executed and delivered in order to set forth
the terms and conditions upon which the indebtedness evidenced hereby is to be
paid to Payee by Makers, together with interest thereon as set forth herein, to
provide for the subordination of such payment in certain circumstances, and to
provide for a guarantee of and security for the payment all amounts due Payee
from Makers hereunder;

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants herein contained, the parties hereto agree as follows:

     1.  Promise to Pay.  Makers hereby jointly and severally promise to pay to
         ---------------

may designate and so notify Makers, the principal sum of ONE MILLION SEVEN
HUNDRED SEVENTY-ONE THOUSAND DOLLARS ($1,771,000.00), with interest thereon from
the date hereof at the rate of seven percent (7%) per annum through June 30,
2001 and at the rate of nine percent (9%) per annum from July 1, 2001 through
June 30, 2006, principal and interest payable as follows:

                                       
<PAGE>
 
          (a) Unless sooner due as hereinafter provided, but subject in all
events to the provisions of Section 2 below, in sixty (60) payments of interest
only, with each such payment due and payable on the last day of each succeeding
calendar month commencing on July 31, 1996 and continuing through and until June
30, 2001, followed by sixty (60) equal monthly installments of principal and
accrued interest the amount of which will be determined by calculating the
amount necessary to fully amortized the principal remaining on the note as of
June 30, 2001 over 120 months with interest on the unpaid balance accruing from
June 30, 2001 at the rate of nine percent (9%) per annum. Each such installment
shall be due and payable on the last day of each succeeding calendar month
commencing on July 31, 2001 and continuing through and until June 30, 2006, on
which date the any and all unpaid principal and accrued interest, shall be due
and payable. Any payment pursuant hereto shall first be applied to interest due
and owing at the date of such payment, and whatever remains after the amount of
such interest is deducted from such payment shall be applied to the principal
balance due hereunder, and the interest upon the portion of principal so
credited shall thereupon cease.

          (b) Subject in all events to the provisions of Section 2 below, Makers
shall have the right, without penalty, and to prepay the indebtedness
represented hereby in part or in full at any time or times during the term
hereof.  Any prepayment pursuant hereto shall first be applied to interest due
and owing at the date of such payment, and whatever remains after the amount of
such interest is deducted from such prepayment shall be applied to the principal
balance due hereunder, and the interest upon the portion of principal so
credited shall thereupon cease. In the event that Makers desire to cause the
Company to make any payment to either or both of them that would otherwise
constitute an event of default under the provisions of Section 3(h) below,

of the Facilities Lease for an additional period of five full years.  In the
event that any payment(s) required to be made by the Company under the
Facilities Lease have not been timely made and remain unpaid as of the date on
which any amounts are paid by Makers to Payee hereunder or otherwise, any and
all amounts so paid by Makers to Payee, no matter how designated or described by
Makers, shall first be applied to satisfy all past-due payments payable by the
Company under the Facilities Lease, and whatever remains after the past-due
amount payable under the Facilities Lease is deducted from such payment shall be
applied in satisfaction of amounts payable hereunder.

          (d) If the indebtedness represented hereby is not paid in full at
maturity (or earlier upon the acceleration thereof as provided in Section 4
below), it shall thereupon accrue, and Makers hereby expressly agree to jointly
and severally pay as liquidated damages and not as a penalty, interest on the
remaining unpaid balance of principal and accrued but unpaid interest at the
rate stated above or the highest rate then permitted by law, whichever is
greater, until all unpaid principal and interest is paid in full.

notice of protest, notice of nonpayment and diligence in collecting the
indebtedness represented hereby.

     2.   Subordination.  The payment of principal and interest hereunder is
          --------------

effective for a period of ten full years from the date hereof.  Concurrently
with the execution and delivery hereof, Payee and the Bank are entering into a
mutually acceptable agreement setting forth in more detail the terms and
conditions upon which payments hereunder shall be subordinated to the Senior
Debt.  It is expressly understood, however, that so long as there is no default
in payment of principal or interest on the Senior Debt, Makers shall make
payments hereunder when due, and may make prepayments of principal and interest
hereunder.

     3.   Default.  The failure of Makers to fully pay or perform or observe, on
          --------                                                              
a timely basis, any of their obligations hereunder shall constitute a default
hereunder and shall entitle Payee to the rights and remedies provided in Section
4 below.  Without limiting the foregoing, a default hereunder shall occur in the
event that, without the prior written consent of Payee:

          (a) A voluntary or involuntary petition is filed for the bankruptcy or
reorganization of either of the Makers or of the Company under the Federal
bankruptcy or reorganization laws, or if a receiver or keeper is appointed for
either of the Makers or the Company or any of their respective assets, or if
either of the Makers or the Company makes a voluntary assignment for the benefit
of unsecured creditors, or if an attachment is levied against a substantial part
of the assets of either of the Makers or of the Company, and any such event or
condition has not terminated or been removed within thirty (30) days after
commencement of such event or condition;

expenditures exceeding $2,000,000 in the aggregate;

          (d) The Company shall acquire another company for a purchase price of
$1,000,000 or more, whether as an acquisition of stock or assets;

          (e) The Quick Ratio (as defined below) of the Company shall be less
than 0.55 at any time during the first full year following the date hereof, less
than 0.65 at any time during the second full year following the date hereof, or
less than 0.75 at any time thereafter during the continuance hereof, in each
case as reflected in the financial reports from the Company to

                                       3
<PAGE>
 
Payee specified in Section 3(g) below.  For purposes of this Section 3(e), the
Quick Ratio of the Company shall be calculated by dividing (i) the sum of all
cash and cash equivalents and all trade accounts receivable not greater than
sixty (60) days old, by (ii) the sum of all current liabilities, including
principal payments due to the Bank and/or the Makers within twelve (12) months;

          (f) The net tangible net worth of the Company shall at any time be

quarter, and an aged receivables listing as of the end of the calendar quarter,
and (ii) annual financial statements of the Company (within 120 days following
the end of each fiscal year) which have been reviewed by an independent
certified public accounting firm reasonably acceptable to Payee, in all case
prepared in accordance with generally accepted accounting principles applied on
a basis consistent with that on which the historical financial statements of the
Company were prepared prior to the date hereof.

          (h) Makers shall fail to provide to Buyer within 120 days after
December 31 of each suceeding calendar year the personal financial statement of
each of the Makers, prepared on the same basis as the financial statements of
Makers provided in connection with the execution and delivery of the Stock
Purchase Agreement were prepared, and certified in writing by Makers as to the
same level of accuracy as represented in the Stock Purchase Agreement

          (i) The Company shall make any payment or other distribution of any
kind to or for the account or benefit of either or both of the Makers, whether
as salary, fees, expenses, or other remuneration, principal or interest on
loans, dividends, repurchases or redemptions of capital stock, or otherwise,

that the Company shall be entitled to pay or distribute additional amounts to or
for the benefit of either or both of the Makers (subject in all events to any
restrictions imposed thereon by the Bank) if, and only if, an equivalent amount

of principal and interest payable by Makers during the year in question pursuant
to Section 1(a) of this Agreement, and (B) the amount payable by Makers as
income taxes (as reported on their IRS forms K-1) in respect of any year in
question during which an effective "S" election has been made under the Internal
Revenue Code of 1986, as amended.

                                       4
<PAGE>
 
          (j) There shall have occurred an event which constitutes, or with the
passage of time or the giving of notice would constitute, a default under the
Credit Agreement or the Revolving Credit Agreement, and any such event has not
terminated or been removed within ten (10) days after commencement of such
event; or

          (k) There shall have occurred an event which constitutes, or with the
passage of time or the giving of notice would constitute, a default under any or
all of the Stock Purchase Agreement, the Facilities Lease, or any other
agreement to which either the Company or either of the Makers is a party, or by
which any of their respective assets or propertied may be bound, involving an
amount in excess of $100,000 or having a term of six( 6) months or more.

     4.   Remedies of Payee.  Upon the occurrence of a default specified in
          ------------------                                               
Section 3 above, but subject in all events to the provisions of Section 2 above,
the principal amount of the indebtedness then owing hereunder and all unpaid
accrued interest thereon, together with any and all additional indebtedness owed
by Makers to Payee, shall become immediately due and payable, without notice,
presentment or demand of any kind, all of which are expressly waived by Makers.
In such event, Payee may proceed to satisfy such default by enforcing its rights
hereunder in any manner provided by law, which may include, without limitation,
proceeding against the Pledged Stock, the Company and/or the Collateral pursuant
to the provisions of Sections 5, 6 and 7 below.  The amount involved in the
default shall include the costs and expenses, including reasonable attorney's
fees, incurred by Payee in enforcing its rights hereunder.  Payee may exercise
all of his rights and remedies concurrently or in such order as he may
determine, and the failure of Payee to exercise any rights or remedies he may
have upon a default by Makers hereunder shall not be deemed a waiver of any
rights, or a release of the Company or either of the Makers from any obligation,
hereunder unless such waiver or release is given in writing by Payee, and in
such event, no such waiver shall be deemed to constitute a waiver of any
succeeding default.  In the event that Payee is precluded from enforcing any of
its rights hereunder by virtue of the provisions of Section 2 above, and for so
long as the restrictions imposed under Section 2 shall continue, the Company
shall not incur any new interest bearing indebtedness for borrowed money, make
any new capital expenditures, acquire any other company, whether as an
acquisition of stock or assets, or enter into any transaction specified in
Section 3(b) above.

     5.   Pledged Stock.
          --------------

          (a) As security for the prompt and full performance by Makers of all
of their obligations hereunder, Makers hereby jointly and severally grant a

in the Shares.  The Shares, together with any substituted or additional shares
of other securities issued on account of any securities subject to this
Agreement pursuant

                                       5

losses, claims, damages, liabilities, costs and expenses, including reasonable

upon advice of its counsel given with respect to any questions relating to the
duties and responsibilities of the Pledgeholder hereunder, or (ii) any action
taken or omitted in reliance upon any instrument, including the written advice
provided for herein, not only as to its due execution and the validity and
effectiveness of its provisions, but also as to the truth and accuracy of any
information contained therein, which the Pledgeholder shall in good faith
believe to be genuine, to have been signed or presented by proper person or
persons, and to conform with the provisions hereof. If at any time a dispute
shall exist as to the duties of the Pledgeholder hereunder or the terms hereof,
the Pledgeholder may in its discretion deposit the Pledged Stock with the Clerk
of the Superior Court of the County of Orange, State of California, and may
interplead the parties hereto not later than thirty (30) calendar days
thereafter.  Upon so depositing the Pledged Stock and filing its complaint in

kind, and shall retain all dividend, voting and other rights with respect to any
securities subject hereto, except for the right to sell, assign, encumber or
otherwise transfer the Pledged Stock or any interest therein without the prior
written consent of Payee.

          (d) During the term of this Agreement, the security interest granted
hereby shall also cover any present or future indebtedness or obligations of
Makers to Payee, whether absolute or contingent, which Payee may permit Makers
to incur during the continuance hereof.

<PAGE>
 
          (e) Upon the full and complete discharge of all of the indebtedness
and obligations guaranteed hereby, the Pledged Stock shall be released from the
security interest created hereby.  Pledgeholder will thereupon promptly take
such actions and deliver such documents and instruments as may be necessary to
reconvey and return the Pledged Stock to Makers and to release the security
interest therein created hereby, and this Agreement shall thereafter terminate.

     6.   Guarantee.  Subject in all events to the provisions of Section 2
          ----------                                                      
above, the Company hereby unconditionally guarantees to Payee the payment and
performance of all of the obligations of Makers hereunder.  The obligations of
the Company shall be independent of the obligations of Makers and a separate
action or actions may be brought and prosecuted by Payee against the Company.

or release additional security for the performance of this guarantee or the
payment of the indebtedness and obligations of Makers guaranteed hereby, or to
apply any and all security in whatever manner Payee may determine.  The Company
waives any right to require Payee to proceed against Makers or either of them,
to proceed against or exhaust any security, including without limitation the
Pledged Stock specified in Section 5 above and the Collateral specified in
Section 7 below, or to pursue any other remedy in Payee's power whatsoever.  The
Company waives all demand or notice of nonpayment or nonperformance by Makers of
the indebtedness and obligations hereby guaranteed.  Any indebtedness of Makers
now or hereafter owed to the Company is hereby subordinated to any amounts or
other monies due and payable by Makers to Payee.  The Company agrees to pay
reasonable attorney's fees and all other costs and expenses which may be
incurred by Payee in enforcement of this guarantee.  In the event that the right
to receive the payment and performance of Makers guaranteed hereby is assigned,
this guarantee shall continue and the assignee shall be entitled to the full
benefits hereof.

                                FACILITIES  LEASE
                                -----------------


     This Facilities Lease (the "Lease") is made June 17, 1996, between
Fullerton Holdings, Inc., a California corporation  ("Landlord") and Morehouse-
COWLES, Inc., a California corporation ("Tenant").

     1.   Premises.
          -------- 

          1.1      Description.  Landlord leases to Tenant and Tenant leases
                   -----------                                              
from Landlord the real property and all improvements thereon located at 1600
West Commonwealth Avenue, Fullerton, California 92633 and more particularly
described in Exhibit A hereto  (the "Premises").
             ---------                          

          1.2      Acceptance.  Tenant acknowledges that it has made such
                   ----------                                            
inspections of the Premises as it deems necessary to determine the condition
thereof and that no representations or warranties have been made by Landlord or
its representatives with respect thereto.  Tenant acknowledges that it is
relying solely on its inspections in determining the condition of the Premises
and that it accepts the same in an "as is" condition, except to the extent of
the environmental indemnification made by Landlord for the benefit of Tenant as
set forth in Section 16 hereof.

     2.   Term.
          ---- 

          2.1      Initial Term.  The initial term of this lease shall commence
                   ------------                                                
on June 17, 1996 and end on July 31, 2006, unless sooner terminated pursuant to
any provision hereof.

          2.2      Option to Extend.  Tenant is given the option to extend the
                   ----------------                                           
term of this Lease for a period of five years commencing on the expiration of
the initial term.  The option must be exercised by giving written notice of
exercise to Landlord at least six months, but not more than nine months before
the expiration of the then initial term.  If Tenant is in "Default" (as defined
in Section 17 at either the time of giving the notice of exercise of its option
to extend or on the date the term of extended term is to commence, the exercise
of such option shall be deemed to be ineffective and such option shall
automatically terminate unexercised.  All of the provisions of this Lease shall
remain in effect during any extension of the term of this Lease.

     3.   Rent.
          ---- 

          3.1      Monthly Rent.  Tenant shall pay to Landlord in advance on the
                   ------------                                                 
first day of each month as monthly rent, without deduction, setoff, prior
notice, or demand (a) the sum of Four Thousand Dollars ($4,000) per month
commencing on July 1, 1996 and continuing through the June 30, 2001; and (b) the
sum of Five Thousand Five Hundred Dollars ($5,500) per

                                       1
<PAGE>
 
month commencing on July 1, 2001 and continuing through July 31, 2006. Rent
during any extension of the initial term shall be as set forth in Exhibit B
                                                                  ---------
hereto. Rent for any period which is for less than one full month shall
be pro rated on a daily basis.

       All rent shall be payable in lawful money of the United States to
Landlord at the address to which notices to Landlord are to be given.
 
         3.2    Late Payments.  If Tenant shall neglect or fail to pay the
                -------------                                             
monthly rent or any other amount required to be paid by it under this Lease
within ten days following the date when the same is due and payable, Tenant
shall pay to Landlord, in addition to such unpaid amounts, a late charge equal
to 10% of the past due installment. Tenant acknowledges that the late payment by
Tenant of any installment of any rent or any other sum of money required to be
paid by Tenant under this Lease will cause Landlord to incur certain costs and
expenses not contemplated under this Lease, the exact amount of which costs
being extremely difficult and impractical to fix.  Such costs and expenses shall
include, without limitation, administrative and collection costs, and processing
and accounting expenses and other costs and expenses necessary and incidental
thereto.  Landlord and Tenant agree that the late charge set forth in  this
Section represents a reasonable estimate of such costs and expenses and is fair
compensation to Landlord for its loss suffered by such non-payment by the tenth
day of the month by Tenant.  The interest and late charge provisions contained
herein are in addition to and do not diminish or represent a substitute for any
or all of Landlord's rights contained in this Lease or under applicable law..

         3.3    Net Rental.  It is the intent of Landlord and Tenant that the
                ----------                                                   
monthly rent  payable to Landlord hereunder shall be net to Landlord so that
this Lease shall yield to Landlord the total rent specified in subsection 3.1
each month during the term of this Lease.  Unless otherwise specifically
provided in this Lease, all costs, expenses, and charges of every kind and
nature relating to the Premises which may be attributed to, or become due during
the term of this Lease shall be paid by Tenant as additional rent hereunder.
Such costs, charges and expenses shall be payable upon commencement of this
Lease, notwithstanding the fact that the monthly rent  does not commence at such
time.


     4.  Taxes.
         ----- 

         4.1    Tenant's Obligation.  Commencing on the date hereof, and
                -------------------                                     
continuing thereafter throughout the term of this Lease, Tenant shall pay as
additional rent an amount equal to all taxes (real and personal), excises,
license and permit fees, assessments, utility levies and charges, and other
governmental charges, general and special, ordinary and extraordinary,
unforeseen as well as foreseen, of any kind or nature whatsoever (including, but
not limited to, assessments for public improvements or benefits) which prior to
or during the term of this Lease are assessed, levied or imposed upon, or become
due and payable as a lien against the Premises or any part thereof; upon any
personal property, equipment or other facility used in the operation thereof
(whether or not owned by Tenant); upon the rent and/or income received from
subtenants or licensees of Tenant; and upon any use or occupancy of the Premises
and of

                                       2
<PAGE>
 
any rights, obligations, easements and franchises as may now or hereafter
be appurtenant, or appertain, to the use of the Premises (all of the foregoing
being collectively referred to herein as "Taxes").  If any such Taxes are
payable or may at the option of the taxpayer be paid, in installments, Tenant
may pay the same together with any accrued interest on the unpaid balance of
such Taxes in installments as the same respectively become due.  Any Taxes
relating to a fiscal period of the taxing authority, only a part of which period
is included within the term of this Lease, shall be adjusted as between Landlord
and Tenant as of the commencement and termination of the term of this Lease, so
that Tenant shall pay only that portion of said Taxes relating to the term of
this Lease.  For the purposes of this Section 4, Taxes shall also include any
tax assessed upon or measured by rents, additional rent or other Landlord
receipts from Tenant, and any tax, fee, or license assessed or measured by
expenditures made by Tenant on behalf of Landlord under or in connection with
this Lease.

         4.2    Payment of Taxes.  All Taxes (except real property taxes)
                ----------------                                         
shall be paid directly to the appropriate governmental authority prior to the
delinquency date established by such authority and Tenant shall provide Landlord
with reasonable proof of payment within five days after payment.

                Landlord shall pay all real property taxes attributable to the
Premises and invoice Tenant for the same.  Tenant shall reimburse Landlord
within ten business days of the receipt of each invoice for property taxes.
Landlord may, at its option, invoice Tenant for real property taxes not more
than twenty days' prior to the due date of the then current installment.

                The failure of Tenant to pay the Taxes as and when herein
specified shall, in addition to all other rights and remedies of Landlord
hereunder, subject Tenant to any fine, penalty, interest or costs which Landlord
may incur as a result thereof. If Tenant fails to pay any Taxes as herein
required, Landlord may, at its option, pay the same. Tenant shall pay to
Landlord on demand the amount of the Taxes so paid together with interest
thereon from the date of Landlord's payment to the date of reimbursement by
Tenant at the lesser of 10% per annum or the maximum interest permitted by law.

         4.3    Other Taxes.  If at any time during the term of this Lease
                -----------                                               
the methods of taxation shall be altered so that in lieu of, or as a supplement
to, the whole or any part of the Taxes now levied, assessed or imposed on the
Premises, there shall be levied, assessed or imposed a tax, assessment, levy,
imposition or charge, wholly or partially as a capital levy or otherwise, on the
rents received therefrom, or a tax, assessment, levy (including but not limited
to any municipal, state or federal levy), imposition or charge measured by or
based in whole or in part upon the Premises, this Lease transaction or any
document to which Tenant is a party, creating or transferring an interest or an
estate in the Premises, and imposed upon Landlord, or a license fee measured by
the rent payable under this Lease, then all such taxes, assessments, levies,
impositions, charges or the part thereof so measured or based, shall be deemed
to be included within the term "Taxes" as defined in subsection 4.1, and Tenant
shall pay and discharge the same as herein provided in respect of the payment of
Taxes, it being the intention of the parties hereto

                                       3
<PAGE>
 
that the rent to be paid hereunder shall be paid to Landlord absolutely net
without deduction of any nature whatsoever, foreseeable or unforeseeable.

         4.5    Exclusion from Taxes.  Nothing contained in this Lease shall
                --------------------                                        
require Tenant to pay any franchise, or income tax of Landlord.

     5.  Insurance.
         --------- 

         5.1    Non-Liability of Landlord.  Landlord shall not be liable to
                -------------------------                                  
Tenant for any damage to Tenant or Tenant's property from any cause and Tenant
waives all claims against Landlord for damage to person or property arising for
any reason, except that Landlord shall be liable to Tenant for damage to Tenant
or Tenant's property resulting from the gross negligence or willful misconduct
of Landlord.  The non-liability of Landlord contained in this subsection and
Tenant's indemnification of Landlord in subsection 5.2 shall extend to the
officer, directors,  agents, employees and authorized representatives of
Landlord.

         5.2    Indemnity.  Tenant shall indemnify and hold Landlord harmless
                ---------                                                    
from any and all damages and liability arising out of, connected with or
incidental to the use or occupancy of the Premises (including without
limitation, the construction of any "Improvements" thereto as defined in
subsection 11.5), except that Tenant shall not be liable for any damage arising
out of the gross negligence or willful misconduct of Landlord unless (and only
to the extent) covered by insurance that Tenant is required to provide under the
terms of this Lease.

                The obligation to indemnify shall include reasonable attorneys'
fees and investigation costs and all other reasonable costs, expenses and
liabilities.

         5.3    Insurance by Tenant.  Tenant will carry and maintain
                -------------------                                 
throughout the term of this Lease, at Tenant's sole cost and expense, the
insurance currently maintained on the Premises, as set forth in Exhibit C
                                                                ---------
hereto, subject to increases in the liability limits as may be recommended from
time to time by Landlord's insurance agent or consultant, provided such
recommendations are consistent with industry practices.

         5.4    Failure by Tenant to Maintain Insurance.  If Tenant fails to
                ---------------------------------------                     
maintain the insurance policies required under the provisions of Section 5,
Landlord, may, at its option, secure and maintain such insurance policies and
Tenant shall reimburse Landlord on demand for the cost of such policies together
with interest thereon from the date of purchase by Landlord to the date of
reimbursement by Tenant at the lesser of 10% per annum or the maximum amount
permitted by law.

     6.  Destruction.
         ----------- 

         6.1      Risk Fully or Partially Covered by Insurance.  If, during the
                  --------------------------------------------                 
term of this Lease, the Premises are totally or partially destroyed or damaged
from a risk covered by the insurance described in Section 5, such damage or
destruction shall not terminate this Lease, and

                                       4
<PAGE>
 
Tenant shall restore the Premises to the extent of the available insurance
proceeds. If the cost of the restoration exceeds the amount of insurance
proceeds received, if any, (the "Shortfall") and Tenant did not comply with its
insurance obligations herein, Tenant shall be responsible for the Shortfall. If
Tenant complied with its insurance obligations hereunder, Landlord may, at its
option, either (a) accept responsibility for the Shortfall, in which case this
Lease shall continue in full force and effect, or (b) notify Tenant of its
intent to terminate this Lease immediately. Landlord shall advise Tenant of its
election in writing within 30 days after the amount of the Shortfall has been
determined.

          Restoration of the Premises by Tenant shall include restoration of all
furniture, fixtures, equipment, improvements, alterations, additions, and
personal property located at the Premises.

     6.2  Risk Not Covered by Insurance.  If, during the term of this
          -----------------------------                              
Lease, the Premises are totally or partially destroyed or damaged from a risk
not covered by the insurance described in Section 5, Landlord may, at its
option, either (a) restore the Premises at Landlord's expense, as soon as
reasonably possible, in which case this Lease shall continue in full force and
effect; or (b) notify Tenant of its intent to terminate this Lease immediately.
Landlord shall advise Tenant of its election in writing within 30 days after the
date of the damage or destruction.

          If Landlord elects to terminate this Lease, Tenant, within 30 days
after receiving Landlord's notice to terminate, may pay into a joint bank
account (with Landlord or its representative as a required co-signor) the full
amount of the estimated cost of restoration, in which event Tenant may proceed
to restore the Premises at its expense.  In such case this Lease shall not
terminate.

          If Landlord elects to terminate this Lease and Tenant does not deposit
the estimated cost of the restoration in the bank account described above, this
Lease shall then terminate.

          If Landlord elects to restore the Premises, Landlord shall not be
required to restore alterations or improvements made by Tenant, Tenant's trade
fixtures or other personal property, such excluded items being the sole
responsibility of Tenant to restore.  If Landlord does not complete restoration
of the Premises within six months from the date of damage or destruction, Tenant
may then terminate this Lease.

     6.3  Loss During Last Part of Term. Notwithstanding the provisions of
          -----------------------------                      
subsections 6.1 and 6.2, if the Premises are totally or partially destroyed or
damaged during the last six months of the term of this Lease rendering the
Premises totally or significantly inaccessible or unusable, Tenant may terminate
this Lease by giving written notice to Landlord not more than 20 days after the
destruction.

                                       5
<PAGE>
 
          6.4      Abatement of Rent.  In the event of damage or destruction
                   -----------------                                        
there shall be no abatement or reduction of rent for the first six (6) months of
any time in which the Premise, in part of whole, cannot be used.  Thereafter,
however, rent shall abate in proportion to the portion of the Premises that is
still not usable; provided that to the extent that Tenant is obligated to
restore the Premises, it is diligently pursuing completion of such restoration.

          6.5      Waiver.  Tenant waives any rights it might otherwise have
                   ------                                                   
under applicable law to terminate this Lease due to any damage or destruction of
the Premises.

          6.6      Legal Restrictions.  If existing laws do not permit
                   ------------------                                 
restoration of the Premises following damage or destruction, either party can
terminate this Lease immediately by giving notice to the other party.

     7.   Utilities, Etc.  Tenant shall be responsible for obtaining and the
          --------------                                                    
payment of  all  utilities  provided to the Premises, including, without
limitation, water, sewer, electrical, telephone and gas.

     8.   Conduct of Business.
          ------------------- 

          8.1      Permitted Use.  Tenant shall use the Premises for the purpose
                   -------------                                                
of conducting a business of the type and quality presently operated from the
Premises, and for no other use without Landlord's consent.

          8.2      Limitations on Use.  Tenant's use of the Premises as provided
                   ------------------                                           
in this Lease shall be in accordance with the following:

                   a.   Cancellation of Insurance.  Tenant shall not do, grant
                        -------------------------                             
or keep anything in, on or about the Premises that will cause a cancellation of
any insurance covering the Premises.

                   b.   Compliance with Laws.  Tenant shall obtain at its sole
                        --------------------                                  
cost all licenses, permits, certificates, variances and approvals  necessary for
the operation of its business and shall comply with all other laws, ordinances,
regulations and orders of all governmental entities concerning the Premises or
Tenant's uses of the same, including, without limitation, (i) those pertaining
to the protection of the environment and the handling, storage,  and/or
disposition of hazardous waste materials, and (ii) the obligation at Tenant's
cost to alter, maintain or restore the Premises in compliance and conformity
with all laws (whether now existing or hereafter enacted) relating to the
condition, use or occupancy of the Premises during the term of this Lease.  The
judgment of any court of competent jurisdiction or the admission of Tenant in
any action or proceeding against it, that Tenant has violated any such laws,
ordinances or regulations shall be conclusive as between Landlord and Tenant.

                   c.   Waste.  Tenant shall not use the Premises in any manner
                        -----                                                  
that will constitute waste, nuisance or unreasonable annoyance.

                                       6
<PAGE>
 
                   d.   Overloading.  Tenant shall not do anything on the
                        -----------                                      
Premises that will cause damage to it, reasonable wear and tear excepted.  The
Premises' foundations, floors, and other structural components shall not be
overloaded.  No machinery, apparatus or other appliance shall be used or
operated in or on the Premises that will in any manner injure the Premises,
whether by vibration or otherwise.

                   e.   Maintenance.  The Premises shall be kept by Tenant in
                        -----------                                          
clean condition, free from any objectionable noises, odors or nuisances, and all
health and police regulations shall in all respects and at all times be fully
complied with by Tenant.

       9.   Assignment or Sublease. Tenant shall not (voluntarily or
            ----------------------                                  
involuntarily) transfer, assign, sublet, enter into license or concession
agreements, change ownership, mortgage, encumber  hypothecate or otherwise
transfer this Lease or Tenant's interest in and to the Premises (collectively
"Assignment") to any third party ("Assignee") without the prior written consent
of Landlord, which consent shall not be unreasonably withheld.  By way of
example and not limitation, Landlord may take into account in determining
whether to grant its consent to a proposed Assignment, the proposed Assignee's
business reputation, experience, and financial condition.  Tenant shall not be
entitled to an Assignment of this Lease while it is in Default hereunder.  Any
Assignment made without Landlord's consent shall be voidable and, at Landlord's
election, shall constitute a "Default" under Section 17.   No Assignment,
whether with or without Landlord's consent, shall relieve Tenant from its
covenants and obligations for the term of this Lease.  In the event any payments
are to be made by an Assignee to Tenant in connection with this Lease or the
Assignment thereof in excess of the rent provided for hereunder, such payments
shall be deemed to be additional rent due Landlord hereunder and shall be
promptly paid by Tenant to Landlord.  If Assignee's tenancy terminates prior to
the expiration of this Lease for any reason, Tenant shall be given a credit
against the remaining monthly rent due under Section 3.1 hereof equal to the
amount of any excess monthly rent actually paid by Assignee.  Such credit shall
be applied against future monthly rent installments in inverse order of
maturity.  It shall not be applied to any other obligations of Tenant hereunder,
including, without limitation, payment of Taxes, insurance, utilities and
maintenance costs.

       10.  Personal Property and Equipment.  Any trade fixtures, equipment and
            -------------------------------                                    
other personal property of Tenant not permanently affixed to the Premises shall
remain the property of Tenant.  Tenant shall have the right to remove any of its
personal property from time to time.


       11.  Maintenance, Repairs and Alterations.
            ------------------------------------ 

            11.1   Tenant's Obligations.  Tenant shall keep in good order,
                   --------------------                                   
condition and repair the Premises and every part thereof, structural and
nonstructural ordinary wear and tear excepted (whether or not such portion of
the Premises requiring repair, or the means of repairing the same are reasonably
or readily accessible to Tenant, and whether or not the need for such repairs
occurs as the result of Tenant's use, any prior use, the elements or age of such
portion of the Premises).

                                       7
<PAGE>
 
          11.2     Landlord's Rights.  If Tenant fails to perform Tenant's
                   -----------------                                      
obligations under this Section 11, Landlord may at its option (but shall not be
required to) enter upon the Premises after five days prior written notice to
Tenant, and put the same in good order, condition and repair and the cost
thereof together with interest thereon at the rate of the lesser of 10% per
annum or the maximum amount permitted by law shall become due and payable as
additional rent to Landlord together with Tenant's next rental installment.  In
the event of emergency repairs, no prior notice shall be required.

          11.3     Landlord's Obligations.  It is intended by the parties hereto
                   ----------------------                                       
that Landlord shall have no obligation, in any manner whatsoever, to repair and
maintain the Premises, whether structural or nonstructural, all of which
obligations are intended to be that of Tenant.  Tenant expressly waives the
benefit of any statute now or hereinafter in effect which would otherwise afford
Tenant the right to make repairs at Landlord's expense or to terminate this
Lease because of Landlord's failure to keep the Premises in good order,
condition and repair.

          11.4     Alterations and Additions.  Tenant may at its own expense and
                   -------------------------                                    
upon prior written notice to Landlord, from time to time during the term hereof,
make alterations, improvements and additions in and to the interior of the
Premises (except those of a structural nature) at a time necessary or convenient
for its purposes provided that the value of the Premises is not hereby
diminished and provided further that no alterations, additions or improvements
(collectively "Improvements") costing in excess of $10,000 may be made without
prior written approval of Landlord.  All Improvements shall be in conformance
with all applicable zoning and related usage laws, and any and all applicable
building and construction codes.

                   All Improvements which require the approval of Landlord
(structural or those costing in excess of $10,000) shall be under the
supervision of a licensed contractor (or licensed architect or licensed
structural engineer, if required by the contractor) and the Improvements shall
be made in accordance with detailed plans and specifications with respect
thereto, approved in writing by Landlord before the commencement of work. All
work with respect to any Improvements must be done in a workmanlike manner and
diligently prosecuted to completion.

                   Tenant shall pay, when due, all claims for labor and
materials furnished or alleged to have been furnished to or for Tenant at or for
use on the Premises, which claims are or may be secured by a mechanic's or
materialmen's lien against the Premises or any interest therein. Tenant shall
give Landlord not less than ten days notice prior to the commencement of any
work on the Premises, and Landlord shall have the right to post notices of
nonresponsibility in and on the Premises as provided by law. If required or
requested by Landlord or its mortgage lender, Tenant shall cause performance and
payment bonds to be posted by a surety licensed and qualified to do business in
the State of California.

                   Any Improvements made shall remain on and be surrendered with
the Premises on expiration or termination of the term, except that Landlord can
elect within 30 days before expiration of the term, or within five days after
termination thereof, to require Tenant

                                       8
<PAGE>
 
to remove any Improvements that Tenant has made to the Premises. If Landlord so
elects, Tenant at its cost shall restore the Premises to the condition existing
prior to the installation of the Improvements to be removed, before the last day
of the term, or within 30 days after notice of election is given, whichever is
later.

       12.  Mechanics' Liens.  Tenant will keep the Premises, the Improvements
            ----------------                                                  
thereon, and Tenant's leasehold interest free and clear of all mechanics' liens
and other liens on account of work done for Tenant or persons claiming under it.
Tenant may contest any lien if, immediately on demand by Landlord, Tenant
obtains and records a lien release bond issued by a surety authorized to issue
surety bonds in California in such amount and form as is required by applicable
law.

       13.  Right of Entry.  Landlord and its authorized representatives shall
            --------------                                                    
have the right to enter the Premises at all reasonable times for any of the
following purposes:  1) to determine whether the Premises are in good condition
and whether Tenant is complying with its obligations under this Lease; 2) to do
any necessary maintenance and make any restoration to the Premises that Landlord
has the right or obligation to perform; 3) to serve, post or keep posted any
notices required or allowed under the provisions of this Lease; 4) to post "for
sale" signs at any time during the term, to post "for rent" or "for lease"
during the last six months of the term, or during any period in which Tenant is
in Default; 5) to show the Premises to prospective brokers, agents, buyers,
tenants or persons interested in an exchange, at any time during the term; 6) to
shore the foundations, footings and walls of the building and other improvements
that are a part of the Premises and to erect scaffolding and protective
barricades around and about the Premises and to do any other act or thing
necessary for the safety or preservation of the Premises if any excavation or
other construction is undertaken or is about to be undertaken or performed on
any adjacent property or nearby street.

            Landlord shall not be liable in any manner for any inconvenience,
disturbance, loss of business, nuisance or other damage arising out of
Landlord's entry on the Premises as provided in this Section, except damage
resulting from the gross negligence or willful misconduct of Landlord.

            Tenant shall not be entitled to an abatement or reduction of rent if
Landlord exercises any rights reserved in this section.

       14.  Condemnation.
            ------------ 

            14.1   Condemnation of Entire Premises.  In the event the entire
                   -------------------------------                          
Premises shall be appropriated or taken under the power of eminent domain by any
public or quasi-public authority, the leasehold estate of Tenant shall cease
upon, but not prior to the date when Tenant shall be actually required to yield
possession of the Premises, and all liabilities of Landlord and Tenant hereunder
accruing subsequent to such date shall cease.

            14.2   Partial Condemnation.  In the event more than 25% of the
                   --------------------                                    
square footage of the Premises is taken under the power of eminent domain by any
public or quasi-public

                                       9
<PAGE>
 
authority, or if because of any appropriation or taking regardless of the amount
so taken the continued conduct of Tenant's business on the Premises would be
prevented or substantially impaired, either Landlord or Tenant shall have the
right to terminate this Lease as of the date of such taking; provided, however,
that this right shall be exercisable only if notice of election to exercise it
is given within 15 days after receipt of notice of the appropriation or taking.
Tenant hereby waives any statutory rights of termination which may arise by
reason of any partial taking of the Premises under the power of eminent domain.

            14.3   Continuation of Lease.  In the event this Lease is not
                   ---------------------                                 
terminated in accordance with the provisions of subsection 14.1 or 14.2, this
Lease shall remain in full force and effect as to the portion of the Premises
remaining after the taking, except that the minimum monthly rent shall be
reduced proportionately to the degree the square footage of the building on the
Premises prior to the taking bears to the square footage of such area after the
taking.

            14.4   Condemnation Award.  Any award for the taking of all or any
                   ------------------                                         
part of the Premises under the power of eminent domain, or any payment made
under threat of the exercise of such power, shall be the sole property of
Landlord.  Tenant shall have no claim thereto and hereby irrevocably assigns and
transfers any right it may have to share in the award to Landlord; provided,
however, that Tenant shall be entitled to apply for a separate award expressly
made for the taking of or damage to leasehold improvements made by Tenant and
Tenant's trade fixtures and personal property, so long as such award does not
otherwise diminish Landlord's award.

       15.  Bankruptcy and Insolvency.  It is specifically recognized between
            -------------------------                                        
Landlord and Tenant that this Lease is entered into to a material extent because
of the unique quality and individuality of Tenant and that the continuing
capacity of Tenant to fulfill each and all of its obligations under this Lease
is essential to Landlord.  Accordingly, it is agreed that as an inducement for
Landlord's entering into this Lease, that in the event any of the following
shall occur, neither this Lease nor any interest therein, nor any interest in or
to the Premises shall become an asset of, to, or in any of the below-mentioned
proceedings, nor be passed, transferred or conveyed to any party whatsoever,
whether by operation of law, by judicial order or otherwise (moreover, in any of
the below-enumerated events, Landlord may elect, with or without notice of such
election and with or without entry or other action by Landlord, forthwith to
terminate this Lease; provided, however, that if Landlord should give notice of
such election, it shall be deemed given, and this Lease terminated, upon
transmittal of such notice);

            a.  Should Tenant institute any proceedings under the
Bankruptcy Act, as such now exists or under any amendments or replacements
thereof or under any other act relating to the subject of insolvency or
bankruptcy;

                                       10
<PAGE>
 
                   b.  Should any involuntary proceeding be filed against Tenant
under any such bankruptcy laws and not be dismissed within 60 days;

                   c.  Should Tenant become insolvent or be adjudicated a
bankrupt in any court of competent jurisdiction, or should a receiver or trustee
be appointed of Tenant's property and not removed within 60 days, or should
Tenant make an assignment for the benefit of creditors;

                   d.  Should there occur the attachment, execution or other
judicial seizure of substantially all of Tenant's assets located at the
Premises, or if a writ of attachment is executed on this Lease, and any of the
foregoing are not removed within ten days; or

                   e.  Should this Lease, or any interest therein or to the
Premises, otherwise by operation of law pass to any person or persons other than
Tenant's permitted assigns, unless consented to by Landlord.

       16.  Environmental Indemnity.  Landlord shall indemnify Tenant from all
            -----------------------                                           
costs or liabilities incurred by Tenant as a result of any actions Tenant is
legally required to take following any discovery of  contamination of the
Premises by any hazardous or toxic substance, material or waste which is
regulated by any local governmental authority, the State of California, or the
United States Government; other than contamination that can reasonably be
demonstrated to have been caused by Tenant, its agents, employees, customers,
suppliers, invitees or contractors, or by any third parties following the date
hereof.

       17.  Defaults by Tenant.
            ------------------ 

            17.1   Types of Default.  The occurrence of any of the following
                   ----------------                                         
shall constitute a material default and breach of this Lease by Tenant
("Default"):

                   a.   Rent Default.  The failure by Tenant to make, as and
                        ------------                                        
when due, any payment of rent, additional rent or other charges payable by
Tenant hereunder or to timely discharge any other monetary obligation hereunder.

                   b.   Abandonment.  The abandonment or vacation of the
                        -----------                                     
Premises by Tenant.  As used herein, abandonment and vacation is defined to
include, without limitation, any absence of Tenant's personnel from the Premises
for five consecutive days unless due to damage or destruction of the Premises or
for other causes beyond Tenant's reasonable control which prevent Tenant from
gaining access to the Premises.

                   c.   Assignment.  The failure of Tenant to obtain Landlord's
                        ----------                                             
consent, if required, to an Assignment.  Such failure shall be deemed incurable
and, at Landlord's option, shall constitute an immediate termination of Tenant's
right to possession of the Premises.

                                       11
<PAGE>
 
                   d.   Stock Purchase Transaction.  The occurrence of an event
                        --------------------------                             
which constitutes, or with the passage of time or the giving of notice, or both,
would constitute a default under that certain Stock Purchase Agreement between
Tenant and Summa Industries, a California corporation, dated May 24, 1996 (the
"Stock Purchase Agreement") or  the  instruments or agreements executed pursuant
thereto.

                   e.   Other.  The failure to perform any other provisions of
                        -----                                                 
this Lease where the failure to perform is not cured within 30 days after notice
has been given to Tenant; provided, however, that such notice shall be in lieu
of, and not in addition to, any notice required under California law.  If the
breach cannot be reasonably cured within 30 days, Tenant shall not be in Default
of this Lease if it commences to cure the breach within the 30 day period and
diligently and in good faith continues to cure the breach.

          17.2     Effect of Notices.  The notices specified in Section 19.1
                   -----------------                                        
shall meet the requirements of California law and no further notice shall be
necessary prior to Landlord's assertion of any rights respecting regaining
possession of Premises.  The purpose of the 30 day notice specified in Section
17.1(d) is to extend the notice time requirements of the unlawful detainer
statutes of California.  In all other respects the statutory notice period shall
apply.  Except as might otherwise be provided at law, no notice of default shall
be required under Section 17.1(d).  No notice shall be deemed a forfeiture or a
termination of this Lease unless Landlord so elects in the notice.

     18.  Remedies Upon Default.  Landlord shall have the following remedies
          ---------------------                                             
if Tenant commits a Default.  These remedies are not exclusive.  They are
cumulative and in addition to any other remedies Landlord may have by agreement
or which are now or later allowed by law.

                   a.   Continuation of Lease.  Landlord can continue this Lease
                        ---------------------                                   
in full force and effect, and the Lease will continue in effect as long as
Landlord does not terminate Tenant's right to possession, and Landlord shall
have the right to collect rent when due.  During the period Tenant is in
Default, Landlord can enter the Premises and relet them, or any part of them, to
third parties for Tenant's account.  Tenant shall be liable immediately to
Landlord for all reasonable costs Landlord incurs in reletting the Premises,
including, without limitation, brokers' commissions, expenses of remodeling the
Premises required by the reletting, and like costs.  The reletting can be for a
period shorter or longer than the remaining term of this Lease, subject to
Landlord's duty to mitigate damages.  Tenant shall pay the Landlord the rent
when due under this Lease on the dates the rent is due, less the rent Landlord
receives from any reletting.  No act by Landlord allowed by this section shall
terminate this Lease unless Landlord notifies Tenant that Landlord elects to
terminate this Lease.

                   b.   Termination of Right to Possession.  Landlord can
                        ----------------------------------               
terminate Tenant's right to possession of the Premises at any time.  No act by
Landlord other than giving notice to Tenant shall terminate this Lease.  Acts of
maintenance, efforts to relet the Premises, or the appointment of receiver on
Landlord's initiative to protect Landlord's interest under this Lease shall not
constitute a termination of Tenant's right to possession.

                                       12
<PAGE>
 
          On termination Landlord may re-enter the Premises and take possession
thereof, remove all persons from the Premises, and Tenant shall have no further
claim under the Lease.  Landlord may further take possession of all property of
Tenant and others located on the Premises.  Tenant shall have 5 days after
Landlord takes possession of the Premises within which to recover its property
by paying to Landlord all sums owed to it as well as all costs incurred, if any,
by Landlord in storing the property.  Should Tenant fail to reclaim the property
in such manner, Landlord may sell or dispose of it in any manner Landlord
chooses and apply the proceeds, if any, first against the cost of storage, then
against any other sums owed to Landlord.

          On termination, Landlord also has the right to recover from Tenant:
(i) the worth at the time of the award of the unpaid rent that had been earned
at the time of termination of this Lease; (ii) the worth at the time of the
award of the amount by which the unpaid rent would have been earned after the
date of termination of this Lease until the time of award exceeds the amount of
loss of rent that Tenant proves could have been reasonably avoided; (iii) the
worth at the time of the award of the amount by which the unpaid rent for the
balance of the term after the time of award exceeds the amount of the loss of
rent that Tenant proves could have been reasonably avoided; and (iv) any other
amount, and court costs necessary to compensate Landlord for all detriment
proximately caused by Tenant's default.  The "worth at the time of the award" as
used in (i) and (ii) of this subsection is computed by allowing interest at the
rate of 10% per annum.  "The worth at the time of the award" as referred to in
(iii) of this subsection is computed by discounting the amount at the discount
rate of the Federal Reserve Bank of San Francisco at the time of the award, plus
1%.

          c.  Cure of Tenant's Default.  Landlord, at any time, can
              ------------------------                             
cure the Default at Tenant's cost.  If Landlord, by reason of the Default, pays
any sum or does any act that requires the payment of any sum, the sum paid by
Landlord shall be immediately due from Tenant to Landlord at the time the sum is
paid, and if paid at a later date shall bear interest at the lesser of 10% per
annum or the maximum amount permitted by law from the date the sum is paid by
Landlord until Landlord is reimbursed by Tenant.  The sum, together with
interest upon it, shall be additional rent.

          d.  Waiver.  No delay or omission in the exercise of any
              ------                                              
right or remedy of either party on any breach or Default by the other shall
impair such right or remedy or be construed as a waiver.  All waivers must be in
writing.  The waiver of any single breach or Default shall not be deemed to be a
waiver of any subsequent breach or Default.

     19.  Sale of the Premises.  If Landlord sells or otherwise transfers all
          --------------------                                               
or any portion of the Premises, Landlord, on consummation of the sale or
transfer, shall be released from any liability thereafter asserted under this
Lease.  If any security deposit or prepaid rent has been paid by Tenant,
Landlord can transfer the security deposit or prepaid rent to Landlord's
successor, subject to Tenant's right thereto, and on such transfer Landlord
shall be discharged from any further liability in reference to the security
deposit or prepaid rent.

       20.  Subordination, Attornment and Estoppel Certificate.
            -------------------------------------------------- 

            20.1   Subordination.  Upon written request of Landlord, Tenant
                   -------------                                           
shall subordinate its rights hereunder to the lien of any mortgagee or trustee
under a deed of trust to any bank, insurance company or other lending
institution, or the lien resulting from any other method of financing or
refinancing now or hereafter enforced against the Premises or any portions
thereof, whether now in existence or in the future acquired or constructed, and
to all advances made or hereafter to be made upon the security therefore;
provided, however, such instrument of subordination shall provide that in the
event of foreclosure, or in the event of the exercise of power of sale, a
purchaser shall recognize Tenant's rights under this Lease, provided, Tenant is
not in Default hereunder.

            20.2   Attornment by Tenant.  In the event any proceedings are
                   --------------------                                   
brought for foreclosure or in the event of the exercise of the power of sale
under any mortgage or deed of trust made by Landlord covering the Premises,
Tenant shall attorn to the purchaser upon such foreclosure or sale and recognize
such purchaser as Landlord under this Lease, provided that the purchaser shall
acquire and accept the Premises subject to this Lease.

            20.3   Estoppel Certificate.  Within ten days after request from
                   --------------------                                     
Landlord, Tenant shall execute and deliver, in recordable form, a certificate
stating that this Lease is unmodified and in full force and effect, or in full
force and effect as modified, and stating the modifications.  The certificate
also shall state the amount of minimum monthly rent, the dates to which the rent
has been paid in advance, and the amount of any security deposit or prepaid
rent.

                   Failure to deliver the certificate within such ten days shall
be conclusive upon Tenant that this Lease is in full force and effect and has
not been modified, except as may be represented by Landlord. If Tenant fails to
deliver the certificate within the ten-day period, it shall be deemed to have
irrevocably constituted and appointed Landlord as its special attorney-in-fact
to execute and deliver the certificate to any third party.

     21.    Quitclaim Deed.  Tenant shall execute and deliver to Landlord on the
            --------------                                                      
expiration or termination of this Lease, immediately on Landlord's request, a
quitclaim deed to the Premises in recordable form, designating Landlord as
transferee.

     22.    Holding Over, Successors and Surrender.
            -------------------------------------- 

            22.1   Holding Over.  If Tenant remains in possession of the
                   ------------                                         
Premises after the expiration of the tenancy created hereunder without
Landlord's written consent and without the execution of a new Lease, Tenant, at
the option of Landlord, shall be deemed to be occupying the Premises from month
to month, subject to all the terms and conditions of this Lease insofar as the
same are applicable to a month-to-month tenancy, except for minimum monthly
rent.  The minimum monthly rent for each month of any such month-to-month
tenancy shall be twice the highest monthly rent for the immediately preceding
12-month period.

                                       14
<PAGE>
 
          If Tenant receives Landlord's consent to hold over, Tenant shall be
deemed to be occupying the Premises on a month-to-month basis, subject to all
the terms and conditions of this Lease, except as expressly modified in the
consent.

          22.2     Surrender.  On the last day of the term hereof or two days
                   ---------                                                 
after any sooner termination, Tenant shall surrender the Premises and all
Improvements to Landlord in good condition and repair, broom clean, ordinary
wear and tear excepted.  Within such time periods, Tenant shall have removed its
personal property from the Premises (unless Landlord has exercised its rights
against such property arising out of a Default hereunder) and repaired any
damage to the Premises occasioned by such removal, which repairs shall include
the patching and filling of holes and repair of structural damage.

          Landlord can elect to retain or dispose of in any manner any of
Tenant's personal property that Tenant does not remove from the Premises within
the time periods stated in the preceding paragraph by giving at least five days
notice to Tenant.  Tenant may recover its property during such five-day period
by paying to Landlord all sums owed to it as well as Landlord's reasonable costs
of removing and storing the property.  Title to the personal property that
Tenant does not recover and that Landlord elects to retain or dispose of on
expiration of the five-day period shall vest in Landlord.  Tenant waives all
claims against Landlord for any damage to Tenant resulting from Landlord's
retention or disposition of any personal property.  Regardless of whether Tenant
recovers its personal property, Tenant shall be liable to Landlord for
Landlord's reasonable costs of storing, removing and disposing of any personal
property.

          If Tenant fails to surrender the Premises to Landlord on expiration or
two days after termination of the term as required by this subsection, Tenant
shall hold Landlord harmless from all damages resulting from Tenant's failure to
surrender the Premises, including, without limitation, claims made by a
succeeding tenant resulting from Tenant's failure to surrender the Premises,
unless Landlord has consented to Tenant's holding over.

       23.  Dedication.
            ---------- 

            23.1   Dedication.  Tenant covenants and agrees to join with

district of which said Premises are or may become a part, or in any other
similar action affecting the Premises.  Tenant also agrees to join in the
execution and/or recordation of any instrument or document necessary in
connection with any of the foregoing.

                      SUMMA INDUSTRIES DIVESTS SUBSIDIARY


June 17, 1996
Fullerton, California


SUMMA INDUSTRIES (NNM:SUMX) announced today that it has completed the sale of
its subsidiary, Morehouse-COWLES, Inc., to a private investment group, for
$750,000 in cash and $1,771,000 in subordinated notes.  SUMMA will not report a
gain or a loss on the sale.  Morehouse-COWLES will continue operations at the
Fullerton facility, which is owned by SUMMA, under a new 10-year lease.

Since SUMMA has reported the results of Morehouse-COWLES as discontinued
operations, the sale will not have a material impact on earnings from continuing
operations.

The office of SUMMA INDUSTRIES, currently located at the Fullerton facility,
will be relocated in Southern California.
